"Resharding" means migrating the data in one slot from one redis server to another, usually happens while increasing/decreasing the number of redis servers. ## Other Features * GUI website dashboard & admin tools * Supports most of Redis commands, Fully compatible with Twemproxy(https://github.com/twitter/twemproxy) * Proxies can register on zk/etcd, clients can avoid dead proxies, see "High Availability" section. ## Tutorial [简体中文](doc/tutorial_zh.md) [English (WIP) ](doc/tutorial_en.md) ## FAQ [简体中文](doc/FAQ_zh.md) [English (WIP) ](FAQ_en.md) ## High Availability [简体中文](doc/tutorial_zh.md#3-jodis-与-ha) [English (WIP) ](doc/tutorial_en.md#ha) ## Architecture ![architecture](doc/pictures/architecture.png) ## Snapshots Proxy ![proxy](doc/pictures/snapshots1.png) Slots ![slots](doc/pictures/snapshots2.png) Group ![group](doc/pictures/snapshots3.png) Sentinel ![sentinel](doc/pictures/snapshots4.png) ## Benchmarks [See benchmark results](doc/benchmark.md) ## Authors Active authors: * [@spinlock9](https://github.com/spinlock) [微博@斯宾洛克](http://weibo.com/spinlock9) * [@yangzhe1991](https://github.com/yangzhe1991) [微博@\_杨肉\_](http://weibo.com/yangzhe1991) Emeritus authors: * [@goroutine](https://github.com/ngaut) [微博@goroutine](http://weibo.com/u/1923497393) * [@c4pt0r](https://github.com/c4pt0r) [微博@Dongxu\_Huang](http://weibo.com/c4pt0r) Thanks: * [@ivanzhaowy](https://github.com/ivanzhaowy) * [@Apache9](https://github.com/apache9) [微博@Apache9](http://weibo.com/u/1876829375) ## License Codis is licensed under MIT， see MIT-LICENSE.txt ------------- *You are welcome to use Codis in your product, and feel free to let us know~ :)* ================================================ FILE: admin/codis-dashboard-admin.sh ================================================ #!/usr/bin/env bash CODIS_ADMIN="${BASH_SOURCE-$0}" CODIS_ADMIN="$(dirname "${CODIS_ADMIN}")" CODIS_ADMIN_DIR="$(cd "${CODIS_ADMIN}"; pwd)" CODIS_BIN_DIR=$CODIS_ADMIN_DIR/../bin CODIS_LOG_DIR=$CODIS_ADMIN_DIR/../log CODIS_CONF_DIR=$CODIS_ADMIN_DIR/../config CODIS_DASHBOARD_BIN=$CODIS_BIN_DIR/codis-dashboard CODIS_ADMIN_TOOL_BIN=$CODIS_BIN_DIR/codis-admin CODIS_DASHBOARD_PID_FILE=$CODIS_BIN_DIR/codis-dashboard.pid CODIS_DASHBOARD_LOG_FILE=$CODIS_LOG_DIR/codis-dashboard.log CODIS_DASHBOARD_DAEMON_FILE=$CODIS_LOG_DIR/codis-dashboard.out CODIS_DASHBOARD_CONF_FILE=$CODIS_CONF_DIR/dashboard.toml echo $CODIS_DASHBOARD_CONF_FILE if [ ! -d $CODIS_LOG_DIR ]; then mkdir -p $CODIS_LOG_DIR fi case $1 in start) echo "starting codis-dashboard ...

Use slaveof to make a Redis instance a copy of # another Redis server. A few things to understand ASAP about Redis replication. # # 1) Redis replication is asynchronous, but you can configure a master to # stop accepting writes if it appears to be not connected with at least # a given number of slaves. # 2) Redis slaves are able to perform a partial resynchronization with the # master if the replication link is lost for a relatively small amount of # time. You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. After a # network partition slaves automatically try to reconnect to masters # and resynchronize with them. # # slaveof # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the slave to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the slave request. # masterauth {{ product_auth }} # When a slave loses its connection with the master, or when the replication # is still in progress, the slave can act in two different ways: # # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will # still reply to client requests, possibly with out of date data, or the # data set may just be empty if this is the first synchronization. # # 2) if slave-serve-stale-data is set to 'no' the slave will reply with # an error "SYNC with master in progress" to all the kind of commands # but to INFO and SLAVEOF. # slave-serve-stale-data yes # You can configure a slave instance to accept writes or not. Writing against # a slave instance may be useful to store some ephemeral data (because data # written on a slave will be easily deleted after resync with the master) but # may also cause problems if clients are writing to it because of a # misconfiguration. # # Since Redis 2.6 by default slaves are read-only. # # Note: read only slaves are not designed to be exposed to untrusted clients # on the internet. It's just a protection layer against misuse of the instance. # Still a read only slave exports by default all the administrative commands # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve # security of read only slaves using 'rename-command' to shadow all the # administrative / dangerous commands. slave-read-only yes # Replication SYNC strategy: disk or socket. # # ------------------------------------------------------- # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY # ------------------------------------------------------- # # New slaves and reconnecting slaves that are not able to continue the replication # process just receiving differences, need to do what is called a "full # synchronization". An RDB file is transmitted from the master to the slaves. # The transmission can happen in two different ways: # # 1) Disk-backed: The Redis master creates a new process that writes the RDB # file on disk. Later the file is transferred by the parent # process to the slaves incrementally. # 2) Diskless: The Redis master creates a new process that directly writes the # RDB file to slave sockets, without touching the disk at all. # # With disk-backed replication, while the RDB file is generated, more slaves # can be queued and served with the RDB file as soon as the current child producing # the RDB file finishes its work. With diskless replication instead once # the transfer starts, new slaves arriving will be queued and a new transfer # will start when the current one terminates. # # When diskless replication is used, the master waits a configurable amount of # time (in seconds) before starting the transfer in the hope that multiple slaves # will arrive and the transfer can be parallelized. # # With slow disks and fast (large bandwidth) networks, diskless replication # works better. repl-diskless-sync no # When diskless replication is enabled, it is possible to configure the delay # the server waits in order to spawn the child that transfers the RDB via socket # to the slaves. # # This is important since once the transfer starts, it is not possible to serve # new slaves arriving, that will be queued for the next RDB transfer, so the server # waits a delay in order to let more slaves arrive. # # The delay is specified in seconds, and by default is 5 seconds. To disable # it entirely just set it to 0 seconds and the transfer will start ASAP. repl-diskless-sync-delay 5 # Slaves send PINGs to server in a predefined interval. It's possible to change # this interval with the repl_ping_slave_period option. The default value is 10 # seconds. # # repl-ping-slave-period 10 # The following option sets the replication timeout for: # # 1) Bulk transfer I/O during SYNC, from the point of view of slave. # 2) Master timeout from the point of view of slaves (data, pings). # 3) Slave timeout from the point of view of masters (REPLCONF ACK pings). # # It is important to make sure that this value is greater than the value # specified for repl-ping-slave-period otherwise a timeout will be detected # every time there is low traffic between the master and the slave. # # repl-timeout 60 # Disable TCP_NODELAY on the slave socket after SYNC? # # If you select "yes" Redis will use a smaller number of TCP packets and # less bandwidth to send data to slaves. But this can add a delay for # the data to appear on the slave side, up to 40 milliseconds with # Linux kernels using a default configuration. # # If you select "no" the delay for data to appear on the slave side will # be reduced but more bandwidth will be used for replication. # # By default we optimize for low latency, but in very high traffic conditions # or when the master and slaves are many hops away, turning this to "yes" may # be a good idea. repl-disable-tcp-nodelay no # Set the replication backlog size. The backlog is a buffer that accumulates # slave data when slaves are disconnected for some time, so that when a slave # wants to reconnect again, often a full resync is not needed, but a partial # resync is enough, just passing the portion of data the slave missed while # disconnected. # # The bigger the replication backlog, the longer the time the slave can be # disconnected and later be able to perform a partial resynchronization. # # The backlog is only allocated once there is at least a slave connected. # # repl-backlog-size 1mb # After a master has no longer connected slaves for some time, the backlog # will be freed. The following option configures the amount of seconds that # need to elapse, starting from the time the last slave disconnected, for # the backlog buffer to be freed. # # A value of 0 means to never release the backlog. # # repl-backlog-ttl 3600 # The slave priority is an integer number published by Redis in the INFO output. # It is used by Redis Sentinel in order to select a slave to promote into a # master if the master is no longer working correctly. # # A slave with a low priority number is considered better for promotion, so # for instance if there are three slaves with priority 10, 100, 25 Sentinel will # pick the one with priority 10, that is the lowest. # # However a special priority of 0 marks the slave as not able to perform the # role of master, so a slave with priority of 0 will never be selected by # Redis Sentinel for promotion. # # By default the priority is 100. slave-priority 100 # It is possible for a master to stop accepting writes if there are less than # N slaves connected, having a lag less or equal than M seconds. # # The N slaves need to be in "online" state. # # The lag in seconds, that must be <= the specified value, is calculated from # the last ping received from the slave, that is usually sent every second. # # This option does not GUARANTEE that N replicas will accept the write, but # will limit the window of exposure for lost writes in case not enough slaves # are available, to the specified number of seconds. # # For example to require at least 3 slaves with a lag <= 10 seconds use: # # min-slaves-to-write 3 # min-slaves-max-lag 10 # # Setting one or the other to 0 disables the feature. # # By default min-slaves-to-write is set to 0 (feature disabled) and # min-slaves-max-lag is set to 10. # A Redis master is able to list the address and port of the attached # slaves in different ways. For example the "INFO replication" section # offers this information, which is used, among other tools, by # Redis Sentinel in order to discover slave instances. # Another place where this info is available is in the output of the # "ROLE" command of a masteer. # # The listed IP and address normally reported by a slave is obtained # in the following way: # # IP: The address is auto detected by checking the peer address # of the socket used by the slave to connect with the master. # # Port: The port is communicated by the slave during the replication # handshake, and is normally the port that the slave is using to # list for connections. # # However when port forwarding or Network Address Translation (NAT) is # used, the slave may be actually reachable via different IP and port # pairs. The following two options can be used by a slave in order to # report to its master a specific set of IP and port, so that both INFO # and ROLE will report those values. # # There is no need to use both the options if you need to override just # the port or the IP address. # # slave-announce-ip 5.5.5.5 # slave-announce-port 1234 ################################## SECURITY ################################### # Require clients to issue AUTH before processing any other # commands. This might be useful in environments in which you do not trust # others with access to the host running redis-server. # # This should stay commented out for backward compatibility and because most # people do not need auth (e.g. they run their own servers). # # Warning: since Redis is pretty fast an outside user can try up to # 150k passwords per second against a good box. This means that you should # use a very strong password otherwise it will be very easy to break. # requirepass {{ product_auth }} # Command renaming. # # It is possible to change the name of dangerous commands in a shared # environment. For instance the CONFIG command may be renamed into something # hard to guess so that it will still be available for internal-use tools # but not available for general clients. # # Example: # # rename-command CONFIG b840fc02d524045429941cc15f59e41cb7be6c52 # # It is also possible to completely kill a command by renaming it into # an empty string: # # rename-command CONFIG "" # # Please note that changing the name of commands that are logged into the # AOF file or transmitted to slaves may cause problems. ################################### LIMITS #################################### # Set the max number of connected clients at the same time. By default # this limit is set to 10000 clients, however if the Redis server is not # able to configure the process file limit to allow for the specified limit # the max number of allowed clients is set to the current file limit # minus 32 (as Redis reserves a few file descriptors for internal uses). # # Once the limit is reached Redis will close all the new connections sending # an error 'max number of clients reached'. # # maxclients 10000 # Don't use more memory than the specified amount of bytes. # When the memory limit is reached Redis will try to remove keys # according to the eviction policy selected (see maxmemory-policy). # # If Redis can't remove keys according to the policy, or if the policy is # set to 'noeviction', Redis will start to reply with errors to commands # that would use more memory, like SET, LPUSH, and so on, and will continue # to reply to read-only commands like GET. # # This option is usually useful when using Redis as an LRU cache, or to set # a hard memory limit for an instance (using the 'noeviction' policy). # # WARNING: If you have slaves attached to an instance with maxmemory on, # the size of the output buffers needed to feed the slaves are subtracted # from the used memory count, so that network problems / resyncs will # not trigger a loop where keys are evicted, and in turn the output # buffer of slaves is full with DELs of keys evicted triggering the deletion # of more keys, and so forth until the database is completely emptied. # # In short... if you have slaves attached it is suggested that you set a lower # limit for maxmemory so that there is some free RAM on the system for slave # output buffers (but this is not needed if the policy is 'noeviction'). # # maxmemory # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory # is reached. You can select among five behaviors: # # volatile-lru -> remove the key with an expire set using an LRU algorithm # allkeys-lru -> remove any key according to the LRU algorithm # volatile-random -> remove a random key with an expire set # allkeys-random -> remove a random key, any key # volatile-ttl -> remove the key with the nearest expire time (minor TTL) # noeviction -> don't expire at all, just return an error on write operations # # Note: with any of the above policies, Redis will return an error on write # operations, when there are no suitable keys for eviction. # # At the date of writing these commands are: set setnx setex append # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby # getset mset msetnx exec sort # # The default is: # # maxmemory-policy noeviction # LRU and minimal TTL algorithms are not precise algorithms but approximated # algorithms (in order to save memory), so you can tune it for speed or # accuracy. For default Redis will check five keys and pick the one that was # used less recently, you can change the sample size using the following # configuration directive. # # The default of 5 produces good enough results. 10 Approximates very closely # true LRU but costs a bit more CPU. 3 is very fast but not very accurate. # # maxmemory-samples 5 ############################## APPEND ONLY MODE ############################### # By default Redis asynchronously dumps the dataset on disk. This mode is # good enough in many applications, but an issue with the Redis process or # a power outage may result into a few minutes of writes lost (depending on # the configured save points). # # The Append Only File is an alternative persistence mode that provides # much better durability. For instance using the default data fsync policy # (see later in the config file) Redis can lose just one second of writes in a # dramatic event like a server power outage, or a single write if something # wrong with the Redis process itself happens, but the operating system is # still running correctly. # # AOF and RDB persistence can be enabled at the same time without problems. # If the AOF is enabled on startup Redis will load the AOF, that is the file # with the better durability guarantees. # # Please check http://redis.io/topics/persistence for more information. appendonly no # The name of the append only file (default: "appendonly.aof") appendfilename "appendonly.aof" # The fsync() call tells the Operating System to actually write data on disk # instead of waiting for more data in the output buffer. Some OS will really flush # data on disk, some other OS will just try to do it ASAP. # # Redis supports three different modes: # # no: don't fsync, just let the OS flush the data when it wants.

In order to start a Redis instance as a # cluster node enable the cluster support uncommenting the following: # # cluster-enabled yes # Every cluster node has a cluster configuration file. This file is not # intended to be edited by hand. It is created and updated by Redis nodes. # Every Redis Cluster node requires a different cluster configuration file. # Make sure that instances running in the same system do not have # overlapping cluster configuration file names. # # cluster-config-file nodes-6379.conf # Cluster node timeout is the amount of milliseconds a node must be unreachable # for it to be considered in failure state. # Most other internal time limits are multiple of the node timeout. # # cluster-node-timeout 15000 # A slave of a failing master will avoid to start a failover if its data # looks too old. # # There is no simple way for a slave to actually have a exact measure of # its "data age", so the following two checks are performed: # # 1) If there are multiple slaves able to failover, they exchange messages # in order to try to give an advantage to the slave with the best # replication offset (more data from the master processed). # Slaves will try to get their rank by offset, and apply to the start # of the failover a delay proportional to their rank. # # 2) Every single slave computes the time of the last interaction with # its master. This can be the last ping or command received (if the master # is still in the "connected" state), or the time that elapsed since the # disconnection with the master (if the replication link is currently down). # If the last interaction is too old, the slave will not try to failover # at all. # # The point "2" can be tuned by user. Specifically a slave will not perform # the failover if, since the last interaction with the master, the time # elapsed is greater than: # # (node-timeout * slave-validity-factor) + repl-ping-slave-period # # So for example if node-timeout is 30 seconds, and the slave-validity-factor # is 10, and assuming a default repl-ping-slave-period of 10 seconds, the # slave will not try to failover if it was not able to talk with the master # for longer than 310 seconds. # # A large slave-validity-factor may allow slaves with too old data to failover # a master, while a too small value may prevent the cluster from being able to # elect a slave at all. # # For maximum availability, it is possible to set the slave-validity-factor # to a value of 0, which means, that slaves will always try to failover the # master regardless of the last time they interacted with the master. # (However they'll always try to apply a delay proportional to their # offset rank). # # Zero is the only value able to guarantee that when all the partitions heal # the cluster will always be able to continue. # # cluster-slave-validity-factor 10 # Cluster slaves are able to migrate to orphaned masters, that are masters # that are left without working slaves. This improves the cluster ability # to resist to failures as otherwise an orphaned master can't be failed over # in case of failure if it has no working slaves. # # Slaves migrate to orphaned masters only if there are still at least a # given number of other working slaves for their old master. This number # is the "migration barrier". A migration barrier of 1 means that a slave # will migrate only if there is at least 1 other working slave for its master # and so forth. It usually reflects the number of slaves you want for every # master in your cluster. # # Default is 1 (slaves migrate only if their masters remain with at least # one slave). To disable migration just set it to a very large value. # A value of 0 can be set but is useful only for debugging and dangerous # in production. # # cluster-migration-barrier 1 # By default Redis Cluster nodes stop accepting queries if they detect there # is at least an hash slot uncovered (no available node is serving it). # This way if the cluster is partially down (for example a range of hash slots # are no longer covered) all the cluster becomes, eventually, unavailable. # It automatically returns available as soon as all the slots are covered again. # # However sometimes you want the subset of the cluster which is working, # to continue to accept queries for the part of the key space that is still # covered. In order to do so, just set the cluster-require-full-coverage # option to no. # # cluster-require-full-coverage yes # In order to setup your cluster make sure to read the documentation # available at http://redis.io web site. ################################## SLOW LOG ################################### # The Redis Slow Log is a system to log queries that exceeded a specified # execution time. The execution time does not include the I/O operations # like talking with the client, sending the reply and so forth, # but just the time needed to actually execute the command (this is the only # stage of command execution where the thread is blocked and can not serve # other requests in the meantime). # # You can configure the slow log with two parameters: one tells Redis # what is the execution time, in microseconds, to exceed in order for the # command to get logged, and the other parameter is the length of the # slow log. When a new command is logged the oldest one is removed from the # queue of logged commands. # The following time is expressed in microseconds, so 1000000 is equivalent # to one second. Note that a negative number disables the slow log, while # a value of zero forces the logging of every command. slowlog-log-slower-than 10000 # There is no limit to this length.

This is useful if you # have a standard template that goes to all Redis servers but also need # to customize a few per-server settings. Include files can include # other files, so use this wisely. # # Notice option "include" won't be rewritten by command "CONFIG REWRITE" # from admin or Redis Sentinel. Since Redis always uses the last processed # line as value of a configuration directive, you'd better put includes # at the beginning of this file to avoid overwriting config change at runtime. # # If instead you are interested in using includes to override configuration # options, it is better to use include as the last line. # # include /path/to/local.conf # include /path/to/other.conf ################################## NETWORK ##################################### # By default, if no "bind" configuration directive is specified, Redis listens # for connections from all the network interfaces available on the server. # It is possible to listen to just one or multiple selected interfaces using # the "bind" configuration directive, followed by one or more IP addresses. # # Examples: # # bind 192.168.1.100 10.0.0.1 # bind 127.0.0.1 ::1 # # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the # internet, binding to all the interfaces is dangerous and will expose the # instance to everybody on the internet. So by default we uncomment the # following bind directive, that will force Redis to listen only into # the IPv4 lookback interface address (this means Redis will be able to # accept connections only from clients running into the same computer it # is running). # # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES # JUST COMMENT THE FOLLOWING LINE. # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bind 127.0.0.1 # Protected mode is a layer of security protection, in order to avoid that # Redis instances left open on the internet are accessed and exploited. # # When protected mode is on and if: # # 1) The server is not binding explicitly to a set of addresses using the # "bind" directive. # 2) No password is configured. # # The server only accepts connections from clients connecting from the # IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain # sockets. # # By default protected mode is enabled. You should disable it only if # you are sure you want clients from other hosts to connect to Redis # even if no authentication is configured, nor a specific set of interfaces # are explicitly listed using the "bind" directive. protected-mode yes # Accept connections on the specified port, default is 6379 (IANA #815344). # If port 0 is specified Redis will not listen on a TCP socket. port 6379 # TCP listen() backlog. # # In high requests-per-second environments you need an high backlog in order # to avoid slow clients connections issues.

Use slaveof to make a Redis instance a copy of # another Redis server. A few things to understand ASAP about Redis replication. # # 1) Redis replication is asynchronous, but you can configure a master to # stop accepting writes if it appears to be not connected with at least # a given number of slaves. # 2) Redis slaves are able to perform a partial resynchronization with the # master if the replication link is lost for a relatively small amount of # time. You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. After a # network partition slaves automatically try to reconnect to masters # and resynchronize with them. # # slaveof # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the slave to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the slave request. # # masterauth # When a slave loses its connection with the master, or when the replication # is still in progress, the slave can act in two different ways: # # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will # still reply to client requests, possibly with out of date data, or the # data set may just be empty if this is the first synchronization. # # 2) if slave-serve-stale-data is set to 'no' the slave will reply with # an error "SYNC with master in progress" to all the kind of commands # but to INFO and SLAVEOF. # slave-serve-stale-data yes # You can configure a slave instance to accept writes or not. Writing against # a slave instance may be useful to store some ephemeral data (because data # written on a slave will be easily deleted after resync with the master) but # may also cause problems if clients are writing to it because of a # misconfiguration. # # Since Redis 2.6 by default slaves are read-only. # # Note: read only slaves are not designed to be exposed to untrusted clients # on the internet. It's just a protection layer against misuse of the instance. # Still a read only slave exports by default all the administrative commands # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve # security of read only slaves using 'rename-command' to shadow all the # administrative / dangerous commands. slave-read-only yes # Replication SYNC strategy: disk or socket. # # ------------------------------------------------------- # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY # ------------------------------------------------------- # # New slaves and reconnecting slaves that are not able to continue the replication # process just receiving differences, need to do what is called a "full # synchronization". An RDB file is transmitted from the master to the slaves. # The transmission can happen in two different ways: # # 1) Disk-backed: The Redis master creates a new process that writes the RDB # file on disk. Later the file is transferred by the parent # process to the slaves incrementally. # 2) Diskless: The Redis master creates a new process that directly writes the # RDB file to slave sockets, without touching the disk at all. # # With disk-backed replication, while the RDB file is generated, more slaves # can be queued and served with the RDB file as soon as the current child producing # the RDB file finishes its work. With diskless replication instead once # the transfer starts, new slaves arriving will be queued and a new transfer # will start when the current one terminates. # # When diskless replication is used, the master waits a configurable amount of # time (in seconds) before starting the transfer in the hope that multiple slaves # will arrive and the transfer can be parallelized. # # With slow disks and fast (large bandwidth) networks, diskless replication # works better. repl-diskless-sync no # When diskless replication is enabled, it is possible to configure the delay # the server waits in order to spawn the child that transfers the RDB via socket # to the slaves. # # This is important since once the transfer starts, it is not possible to serve # new slaves arriving, that will be queued for the next RDB transfer, so the server # waits a delay in order to let more slaves arrive. # # The delay is specified in seconds, and by default is 5 seconds. To disable # it entirely just set it to 0 seconds and the transfer will start ASAP. repl-diskless-sync-delay 5 # Slaves send PINGs to server in a predefined interval. It's possible to change # this interval with the repl_ping_slave_period option. The default value is 10 # seconds. # # repl-ping-slave-period 10 # The following option sets the replication timeout for: # # 1) Bulk transfer I/O during SYNC, from the point of view of slave. # 2) Master timeout from the point of view of slaves (data, pings). # 3) Slave timeout from the point of view of masters (REPLCONF ACK pings). # # It is important to make sure that this value is greater than the value # specified for repl-ping-slave-period otherwise a timeout will be detected # every time there is low traffic between the master and the slave. # # repl-timeout 60 # Disable TCP_NODELAY on the slave socket after SYNC? # # If you select "yes" Redis will use a smaller number of TCP packets and # less bandwidth to send data to slaves. But this can add a delay for # the data to appear on the slave side, up to 40 milliseconds with # Linux kernels using a default configuration. # # If you select "no" the delay for data to appear on the slave side will # be reduced but more bandwidth will be used for replication. # # By default we optimize for low latency, but in very high traffic conditions # or when the master and slaves are many hops away, turning this to "yes" may # be a good idea. repl-disable-tcp-nodelay no # Set the replication backlog size. The backlog is a buffer that accumulates # slave data when slaves are disconnected for some time, so that when a slave # wants to reconnect again, often a full resync is not needed, but a partial # resync is enough, just passing the portion of data the slave missed while # disconnected. # # The bigger the replication backlog, the longer the time the slave can be # disconnected and later be able to perform a partial resynchronization. # # The backlog is only allocated once there is at least a slave connected. # # repl-backlog-size 1mb # After a master has no longer connected slaves for some time, the backlog # will be freed. The following option configures the amount of seconds that # need to elapse, starting from the time the last slave disconnected, for # the backlog buffer to be freed. # # A value of 0 means to never release the backlog. # # repl-backlog-ttl 3600 # The slave priority is an integer number published by Redis in the INFO output. # It is used by Redis Sentinel in order to select a slave to promote into a # master if the master is no longer working correctly. # # A slave with a low priority number is considered better for promotion, so # for instance if there are three slaves with priority 10, 100, 25 Sentinel will # pick the one with priority 10, that is the lowest. # # However a special priority of 0 marks the slave as not able to perform the # role of master, so a slave with priority of 0 will never be selected by # Redis Sentinel for promotion. # # By default the priority is 100. slave-priority 100 # It is possible for a master to stop accepting writes if there are less than # N slaves connected, having a lag less or equal than M seconds. # # The N slaves need to be in "online" state. # # The lag in seconds, that must be <= the specified value, is calculated from # the last ping received from the slave, that is usually sent every second. # # This option does not GUARANTEE that N replicas will accept the write, but # will limit the window of exposure for lost writes in case not enough slaves # are available, to the specified number of seconds. # # For example to require at least 3 slaves with a lag <= 10 seconds use: # # min-slaves-to-write 3 # min-slaves-max-lag 10 # # Setting one or the other to 0 disables the feature. # # By default min-slaves-to-write is set to 0 (feature disabled) and # min-slaves-max-lag is set to 10. # A Redis master is able to list the address and port of the attached # slaves in different ways. For example the "INFO replication" section # offers this information, which is used, among other tools, by # Redis Sentinel in order to discover slave instances. # Another place where this info is available is in the output of the # "ROLE" command of a masteer. # # The listed IP and address normally reported by a slave is obtained # in the following way: # # IP: The address is auto detected by checking the peer address # of the socket used by the slave to connect with the master. # # Port: The port is communicated by the slave during the replication # handshake, and is normally the port that the slave is using to # list for connections. # # However when port forwarding or Network Address Translation (NAT) is # used, the slave may be actually reachable via different IP and port # pairs. The following two options can be used by a slave in order to # report to its master a specific set of IP and port, so that both INFO # and ROLE will report those values. # # There is no need to use both the options if you need to override just # the port or the IP address. # # slave-announce-ip 5.5.5.5 # slave-announce-port 1234 ################################## SECURITY ################################### # Require clients to issue AUTH before processing any other # commands. This might be useful in environments in which you do not trust # others with access to the host running redis-server. # # This should stay commented out for backward compatibility and because most # people do not need auth (e.g. they run their own servers). # # Warning: since Redis is pretty fast an outside user can try up to # 150k passwords per second against a good box.

By default # this limit is set to 10000 clients, however if the Redis server is not # able to configure the process file limit to allow for the specified limit # the max number of allowed clients is set to the current file limit # minus 32 (as Redis reserves a few file descriptors for internal uses). # # Once the limit is reached Redis will close all the new connections sending # an error 'max number of clients reached'. # # maxclients 10000 # Don't use more memory than the specified amount of bytes. # When the memory limit is reached Redis will try to remove keys # according to the eviction policy selected (see maxmemory-policy). # # If Redis can't remove keys according to the policy, or if the policy is # set to 'noeviction', Redis will start to reply with errors to commands # that would use more memory, like SET, LPUSH, and so on, and will continue # to reply to read-only commands like GET. # # This option is usually useful when using Redis as an LRU cache, or to set # a hard memory limit for an instance (using the 'noeviction' policy). # # WARNING: If you have slaves attached to an instance with maxmemory on, # the size of the output buffers needed to feed the slaves are subtracted # from the used memory count, so that network problems / resyncs will # not trigger a loop where keys are evicted, and in turn the output # buffer of slaves is full with DELs of keys evicted triggering the deletion # of more keys, and so forth until the database is completely emptied. # # In short... if you have slaves attached it is suggested that you set a lower # limit for maxmemory so that there is some free RAM on the system for slave # output buffers (but this is not needed if the policy is 'noeviction'). # # maxmemory # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory # is reached. You can select among five behaviors: # # volatile-lru -> remove the key with an expire set using an LRU algorithm # allkeys-lru -> remove any key according to the LRU algorithm # volatile-random -> remove a random key with an expire set # allkeys-random -> remove a random key, any key # volatile-ttl -> remove the key with the nearest expire time (minor TTL) # noeviction -> don't expire at all, just return an error on write operations # # Note: with any of the above policies, Redis will return an error on write # operations, when there are no suitable keys for eviction. # # At the date of writing these commands are: set setnx setex append # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby # getset mset msetnx exec sort # # The default is: # # maxmemory-policy noeviction # LRU and minimal TTL algorithms are not precise algorithms but approximated # algorithms (in order to save memory), so you can tune it for speed or # accuracy. For default Redis will check five keys and pick the one that was # used less recently, you can change the sample size using the following # configuration directive. # # The default of 5 produces good enough results. 10 Approximates very closely # true LRU but costs a bit more CPU. 3 is very fast but not very accurate. # # maxmemory-samples 5 ############################## APPEND ONLY MODE ############################### # By default Redis asynchronously dumps the dataset on disk. This mode is # good enough in many applications, but an issue with the Redis process or # a power outage may result into a few minutes of writes lost (depending on # the configured save points). # # The Append Only File is an alternative persistence mode that provides # much better durability. For instance using the default data fsync policy # (see later in the config file) Redis can lose just one second of writes in a # dramatic event like a server power outage, or a single write if something # wrong with the Redis process itself happens, but the operating system is # still running correctly. # # AOF and RDB persistence can be enabled at the same time without problems. # If the AOF is enabled on startup Redis will load the AOF, that is the file # with the better durability guarantees. # # Please check http://redis.io/topics/persistence for more information. appendonly no # The name of the append only file (default: "appendonly.aof") appendfilename "appendonly.aof" # The fsync() call tells the Operating System to actually write data on disk # instead of waiting for more data in the output buffer. Some OS will really flush # data on disk, some other OS will just try to do it ASAP. # # Redis supports three different modes: # # no: don't fsync, just let the OS flush the data when it wants. Faster. # always: fsync after every write to the append only log. Slow, Safest. # everysec: fsync only one time every second. Compromise. # # The default is "everysec", as that's usually the right compromise between # speed and data safety. It's up to you to understand if you can relax this to # "no" that will let the operating system flush the output buffer when # it wants, for better performances (but if you can live with the idea of # some data loss consider the default persistence mode that's snapshotting), # or on the contrary, use "always" that's very slow but a bit safer than # everysec. # # More details please check the following article: # http://antirez.com/post/redis-persistence-demystified.html # # If unsure, use "everysec". # appendfsync always appendfsync everysec # appendfsync no # When the AOF fsync policy is set to always or everysec, and a background # saving process (a background save or AOF log background rewriting) is # performing a lot of I/O against the disk, in some Linux configurations # Redis may block too long on the fsync() call. Note that there is no fix for # this currently, as even performing fsync in a different thread will block # our synchronous write(2) call. # # In order to mitigate this problem it's possible to use the following option # that will prevent fsync() from being called in the main process while a # BGSAVE or BGREWRITEAOF is in progress. # # This means that while another child is saving, the durability of Redis is # the same as "appendfsync none". In practical terms, this means that it is # possible to lose up to 30 seconds of log in the worst scenario (with the # default Linux settings). # # If you have latency problems turn this to "yes". Otherwise leave it as # "no" that is the safest pick from the point of view of durability. no-appendfsync-on-rewrite no # Automatic rewrite of the append only file. # Redis is able to automatically rewrite the log file implicitly calling # BGREWRITEAOF when the AOF log size grows by the specified percentage. # # This is how it works: Redis remembers the size of the AOF file after the # latest rewrite (if no rewrite has happened since the restart, the size of # the AOF at startup is used). # # This base size is compared to the current size. If the current size is # bigger than the specified percentage, the rewrite is triggered. Also # you need to specify a minimal size for the AOF file to be rewritten, this # is useful to avoid rewriting the AOF file even if the percentage increase # is reached but it is still pretty small. # # Specify a percentage of zero in order to disable the automatic AOF # rewrite feature. auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb # An AOF file may be found to be truncated at the end during the Redis # startup process, when the AOF data gets loaded back into memory. # This may happen when the system where Redis is running # crashes, especially when an ext4 filesystem is mounted without the # data=ordered option (however this can't happen when Redis itself # crashes or aborts but the operating system still works correctly). # # Redis can either exit with an error when this happens, or load as much # data as possible (the default now) and start if the AOF file is found # to be truncated at the end.

In order to start a Redis instance as a # cluster node enable the cluster support uncommenting the following: # # cluster-enabled yes # Every cluster node has a cluster configuration file. This file is not # intended to be edited by hand. It is created and updated by Redis nodes. # Every Redis Cluster node requires a different cluster configuration file. # Make sure that instances running in the same system do not have # overlapping cluster configuration file names. # # cluster-config-file nodes-6379.conf # Cluster node timeout is the amount of milliseconds a node must be unreachable # for it to be considered in failure state. # Most other internal time limits are multiple of the node timeout. # # cluster-node-timeout 15000 # A slave of a failing master will avoid to start a failover if its data # looks too old. # # There is no simple way for a slave to actually have a exact measure of # its "data age", so the following two checks are performed: # # 1) If there are multiple slaves able to failover, they exchange messages # in order to try to give an advantage to the slave with the best # replication offset (more data from the master processed). # Slaves will try to get their rank by offset, and apply to the start # of the failover a delay proportional to their rank. # # 2) Every single slave computes the time of the last interaction with # its master. This can be the last ping or command received (if the master # is still in the "connected" state), or the time that elapsed since the # disconnection with the master (if the replication link is currently down). # If the last interaction is too old, the slave will not try to failover # at all. # # The point "2" can be tuned by user. Specifically a slave will not perform # the failover if, since the last interaction with the master, the time # elapsed is greater than: # # (node-timeout * slave-validity-factor) + repl-ping-slave-period # # So for example if node-timeout is 30 seconds, and the slave-validity-factor # is 10, and assuming a default repl-ping-slave-period of 10 seconds, the # slave will not try to failover if it was not able to talk with the master # for longer than 310 seconds. # # A large slave-validity-factor may allow slaves with too old data to failover # a master, while a too small value may prevent the cluster from being able to # elect a slave at all. # # For maximum availability, it is possible to set the slave-validity-factor # to a value of 0, which means, that slaves will always try to failover the # master regardless of the last time they interacted with the master. # (However they'll always try to apply a delay proportional to their # offset rank). # # Zero is the only value able to guarantee that when all the partitions heal # the cluster will always be able to continue. # # cluster-slave-validity-factor 10 # Cluster slaves are able to migrate to orphaned masters, that are masters # that are left without working slaves. This improves the cluster ability # to resist to failures as otherwise an orphaned master can't be failed over # in case of failure if it has no working slaves. # # Slaves migrate to orphaned masters only if there are still at least a # given number of other working slaves for their old master. This number # is the "migration barrier". A migration barrier of 1 means that a slave # will migrate only if there is at least 1 other working slave for its master # and so forth. It usually reflects the number of slaves you want for every # master in your cluster. # # Default is 1 (slaves migrate only if their masters remain with at least # one slave). To disable migration just set it to a very large value. # A value of 0 can be set but is useful only for debugging and dangerous # in production. # # cluster-migration-barrier 1 # By default Redis Cluster nodes stop accepting queries if they detect there # is at least an hash slot uncovered (no available node is serving it). # This way if the cluster is partially down (for example a range of hash slots # are no longer covered) all the cluster becomes, eventually, unavailable. # It automatically returns available as soon as all the slots are covered again. # # However sometimes you want the subset of the cluster which is working, # to continue to accept queries for the part of the key space that is still # covered. In order to do so, just set the cluster-require-full-coverage # option to no. # # cluster-require-full-coverage yes # In order to setup your cluster make sure to read the documentation # available at http://redis.io web site. ################################## SLOW LOG ################################### # The Redis Slow Log is a system to log queries that exceeded a specified # execution time. The execution time does not include the I/O operations # like talking with the client, sending the reply and so forth, # but just the time needed to actually execute the command (this is the only # stage of command execution where the thread is blocked and can not serve # other requests in the meantime). # # You can configure the slow log with two parameters: one tells Redis # what is the execution time, in microseconds, to exceed in order for the # command to get logged, and the other parameter is the length of the # slow log. When a new command is logged the oldest one is removed from the # queue of logged commands. # The following time is expressed in microseconds, so 1000000 is equivalent # to one second.

These thresholds can be configured using the following directives. hash-max-ziplist-entries 512 hash-max-ziplist-value 64 # Lists are also encoded in a special way to save a lot of space. # The number of entries allowed per internal list node can be specified # as a fixed maximum size or a maximum number of elements. # For a fixed maximum size, use -5 through -1, meaning: # -5: max size: 64 Kb <-- not recommended for normal workloads # -4: max size: 32 Kb <-- not recommended # -3: max size: 16 Kb <-- probably not recommended # -2: max size: 8 Kb <-- good # -1: max size: 4 Kb <-- good # Positive numbers mean store up to _exactly_ that number of elements # per list node. # The highest performing option is usually -2 (8 Kb size) or -1 (4 Kb size), # but if your use case is unique, adjust the settings as necessary. list-max-ziplist-size -2 # Lists may also be compressed. # Compress depth is the number of quicklist ziplist nodes from *each* side of # the list to *exclude* from compression. The head and tail of the list # are always uncompressed for fast push/pop operations. Settings are: # 0: disable all list compression # 1: depth 1 means "don't start compressing until after 1 node into the list, # going from either the head or tail" # So: [head]->node->node->...->node->[tail] # [head], [tail] will always be uncompressed; inner nodes will compress. # 2: [head]->[next]->node->node->...->node->[prev]->[tail] # 2 here means: don't compress head or head->next or tail->prev or tail, # but compress all nodes between them. # 3: [head]->[next]->[next]->node->node->...->node->[prev]->[prev]->[tail] # etc. list-compress-depth 0 # Sets have a special encoding in just one case: when a set is composed # of just strings that happen to be integers in radix 10 in the range # of 64 bit signed integers. # The following configuration setting sets the limit in the size of the # set in order to use this special memory saving encoding. set-max-intset-entries 512 # Similarly to hashes and lists, sorted sets are also specially encoded in # order to save a lot of space.

The limit includes the # 16 bytes header. When an HyperLogLog using the sparse representation crosses # this limit, it is converted into the dense representation. # # A value greater than 16000 is totally useless, since at that point the # dense representation is more memory efficient. # # The suggested value is ~ 3000 in order to have the benefits of # the space efficient encoding without slowing down too much PFADD, # which is O(N) with the sparse encoding. The value can be raised to # ~ 10000 when CPU is not a concern, but space is, and the data set is # composed of many HyperLogLogs with cardinality in the 0 - 15000 range. hll-sparse-max-bytes 3000 # Active rehashing uses 1 millisecond every 100 milliseconds of CPU time in # order to help rehashing the main Redis hash table (the one mapping top-level # keys to values). The hash table implementation Redis uses (see dict.c) # performs a lazy rehashing: the more operation you run into a hash table # that is rehashing, the more rehashing "steps" are performed, so if the # server is idle the rehashing is never complete and some more memory is used # by the hash table. # # The default is to use this millisecond 10 times every second in order to # actively rehash the main dictionaries, freeing memory when possible. # # If unsure: # use "activerehashing no" if you have hard latency requirements and it is # not a good thing in your environment that Redis can reply from time to time # to queries with 2 milliseconds delay. # # use "activerehashing yes" if you don't have such hard requirements but # want to free memory asap when possible. activerehashing yes # The client output buffer limits can be used to force disconnection of clients # that are not reading data from the server fast enough for some reason (a # common reason is that a Pub/Sub client can't consume messages as fast as the # publisher can produce them). # # The limit can be set differently for the three different classes of clients: # # normal -> normal clients including MONITOR clients # slave -> slave clients # pubsub -> clients subscribed to at least one pubsub channel or pattern # # The syntax of every client-output-buffer-limit directive is the following: # # client-output-buffer-limit # # A client is immediately disconnected once the hard limit is reached, or if # the soft limit is reached and remains reached for the specified number of # seconds (continuously). # So for instance if the hard limit is 32 megabytes and the soft limit is # 16 megabytes / 10 seconds, the client will get disconnected immediately # if the size of the output buffers reach 32 megabytes, but will also get # disconnected if the client reaches 16 megabytes and continuously overcomes # the limit for 10 seconds. # # By default normal clients are not limited because they don't receive data # without asking (in a push way), but just after a request, so only # asynchronous clients may create a scenario where data is requested faster # than it can read. # # Instead there is a default limit for pubsub and slave clients, since # subscribers and slaves receive data in a push fashion. # # Both the hard or the soft limit can be disabled by setting them to zero. client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 # Redis calls an internal function to perform many background tasks, like # closing connections of clients in timeout, purging expired keys that are # never requested, and so forth. # # Not all tasks are performed with the same frequency, but Redis checks for # tasks to perform according to the specified "hz" value. # # By default "hz" is set to 10. Raising the value will use more CPU when # Redis is idle, but at the same time will make Redis more responsive when # there are many keys expiring at the same time, and timeouts may be # handled with more precision. # # The range is between 1 and 500, however a value over 100 is usually not # a good idea.

If only announce-port is provided, the # Sentinel will announce the auto-detected local IP and the specified port. # # Example: # # sentinel announce-ip 1.2.3.4 # dir # Every long running process should have a well-defined working directory. # For Redis Sentinel to chdir to /tmp at startup is the simplest thing # for the process to don't interfere with administrative tasks such as # unmounting filesystems. dir /tmp # sentinel monitor # # Tells Sentinel to monitor this master, and to consider it in O_DOWN # (Objectively Down) state only if at least sentinels agree. # # Note that whatever is the ODOWN quorum, a Sentinel will require to # be elected by the majority of the known Sentinels in order to # start a failover, so no failover can be performed in minority. # # Slaves are auto-discovered, so you don't need to specify slaves in # any way. Sentinel itself will rewrite this configuration file adding # the slaves using additional configuration options. # Also note that the configuration file is rewritten when a # slave is promoted to master. # # Note: master name should not include special characters or spaces. # The valid charset is A-z 0-9 and the three characters ".-_". # sentinel monitor mymaster 127.0.0.1 6379 2 # sentinel auth-pass # # Set the password to use to authenticate with the master and slaves. # Useful if there is a password set in the Redis instances to monitor. # # Note that the master password is also used for slaves, so it is not # possible to set a different password in masters and slaves instances # if you want to be able to monitor these instances with Sentinel. # # However you can have Redis instances without the authentication enabled # mixed with Redis instances requiring the authentication (as long as the # password set is the same for all the instances requiring the password) as # the AUTH command will have no effect in Redis instances with authentication # switched off. # # Example: # # sentinel auth-pass mymaster MySUPER--secret-0123passw0rd # sentinel down-after-milliseconds # # Number of milliseconds the master (or any attached slave or sentinel) should # be unreachable (as in, not acceptable reply to PING, continuously, for the # specified period) in order to consider it in S_DOWN state (Subjectively # Down). # # Default is 30 seconds. # sentinel down-after-milliseconds mymaster 30000 # sentinel parallel-syncs # # How many slaves we can reconfigure to point to the new slave simultaneously # during the failover. Use a low number if you use the slaves to serve query # to avoid that all the slaves will be unreachable at about the same # time while performing the synchronization with the master. # sentinel parallel-syncs mymaster 1 # sentinel failover-timeout # # Specifies the failover timeout in milliseconds. It is used in many ways: # # - The time needed to re-start a failover after a previous failover was # already tried against the same master by a given Sentinel, is two # times the failover timeout. # # - The time needed for a slave replicating to a wrong master according # to a Sentinel current configuration, to be forced to replicate # with the right master, is exactly the failover timeout (counting since # the moment a Sentinel detected the misconfiguration). # # - The time needed to cancel a failover that is already in progress but # did not produced any configuration change (SLAVEOF NO ONE yet not # acknowledged by the promoted slave). # # - The maximum time a failover in progress waits for all the slaves to be # reconfigured as slaves of the new master. However even after this time # the slaves will be reconfigured by the Sentinels anyway, but not with # the exact parallel-syncs progression as specified. # # Default is 3 minutes. # sentinel failover-timeout mymaster 180000 # SCRIPTS EXECUTION # # sentinel notification-script and sentinel reconfig-script are used in order # to configure scripts that are called to notify the system administrator # or to reconfigure clients after a failover. The scripts are executed # with the following rules for error handling: # # If script exits with "1" the execution is retried later (up to a maximum # number of times currently set to 10). # # If script exits with "2" (or an higher value) the script execution is # not retried. # # If script terminates because it receives a signal the behavior is the same # as exit code 1. # # A script has a maximum running time of 60 seconds. After this limit is # reached the script is terminated with a SIGKILL and the execution retried. # NOTIFICATION SCRIPT # # sentinel notification-script # # Call the specified notification script for any sentinel event that is # generated in the WARNING level (for instance -sdown, -odown, and so forth). # This script should notify the system administrator via email, SMS, or any # other messaging system, that there is something wrong with the monitored # Redis systems. # # The script is called with just two arguments: the first is the event type # and the second the event description. # # The script must exist and be executable in order for sentinel to start if # this option is provided. # # Example: # # sentinel notification-script mymaster /var/redis/notify.sh # CLIENTS RECONFIGURATION SCRIPT # # sentinel client-reconfig-script # # When the master changed because of a failover a script can be called in # order to perform application-specific tasks to notify the clients that the # configuration has changed and the master is at a different address. # # The following arguments are passed to the script: # # # # is currently always "failover" # is either "leader" or "observer" # # The arguments from-ip, from-port, to-ip, to-port are used to communicate # the old address of the master and the new address of the elected slave # (now a master). # # This script should be resistant to multiple invocations. # # Example: # # sentinel client-reconfig-script mymaster /var/redis/reconfig.sh ================================================ FILE: deploy/Makefile

Codis is a distributed redis service developed by wandoujia infrasstructure team, codis can be viewed as an redis server with infinite memory, have the ability of dynamically elastic scaling, it's more fit for storage business, if you need SUBPUB-like command, Codis is not supported, always remember Codis is a distributed storage system. ###Does Codis support etcd ? Yes, please read the tutorial ####Can I use Codis directly in my existing services? That depends. Two cases: 1) Twemproxy users: Yes, codis fully support twemproxy commands, further more, using redis-port tool, you can synchronization the data on twemproxy onto your Codis cluster. 2) Raw redis users: That depends, if you use the following commands: BGREWRITEAOF, BGSAVE, BITOP, BLPOP, BRPOP, BRPOPLPUSH, CLIENT, CONFIG, DBSIZE, DEBUG, DISCARD, EXEC, FLUSHALL, FLUSHDB, KEYS, LASTSAVE, MIGRATE, MONITOR, MOVE, MSETNX, MULTI, OBJECT, PSUBSCRIBE, PUBLISH, PUNSUBSCRIBE, RANDOMKEY, RENAME, RENAMENX, RESTORE, SAVE, SCAN, SCRIPT, SHUTDOWN, SLAVEOF, SLOTSCHECK, SLOTSDEL, SLOTSINFO, SLOTSMGRTONE, SLOTSMGRTSLOT, SLOTSMGRTTAGONE, SLOTSMGRTTAGSLOT, SLOWLOG, SUBSCRIBE, SYNC, TIME, UNSUBSCRIBE, UNWATCH, WATCH you should modify your code, because Codis does not support these commands. ================================================ FILE: doc/FAQ_zh.md ================================================ ### Codis 是什么? Codis 是 Wandoujia Infrastructure Team 开发的一个分布式 Redis 服务, 用户可以看成是一个无限内存的 Redis 服务, 有动态扩/缩容的能力. 对偏存储型的业务更实用, 如果你需要 SUBPUB 之类的指令, Codis 是不支持的. 时刻记住 Codis 是一个分布式存储的项目. 对于海量的 key, value不太大( <= 1M ), 随着业务扩展缓存也要随之扩展的业务场景有特效. ### 使用 Codis 有什么好处? Redis获得动态扩容/缩容的能力，增减redis实例对client完全透明、不需要重启服务，不需要业务方担心 Redis 内存爆掉的问题. 也不用担心申请太大, 造成浪费. 业务方也不需要自己维护 Redis. Codis支持水平扩容/缩容，扩容可以直接界面的 "Auto Rebalance" 按钮，缩容只需要将要下线的实例拥有的slot迁移到其它实例，然后在界面上删除下线的group即可。 ### 我的服务能直接迁移到 Codis 上吗? 分两种情况: 1) 原来使用 twemproxy 的用户: 可以, 使用codis项目内的redis-port工具, 可以实时的同步 twemproxy 底下的 redis 数据到你的 codis 集群上. 搞定了以后, 只需要你修改一下你的配置, 将 twemproxy 的地址改成 codis 的地址就好了. 除此之外, 你什么事情都不用做. 2) 原来使用 Redis 的用户: 如果你使用了[doc/unsupported_cmds](https://github.com/CodisLabs/codis/blob/master/doc/unsupported_cmds.md)中提到的命令，是无法直接迁移到 Codis 上的. 你需要修改你的代码, 用其他的方式实现. ### 相对于twemproxy的优劣？ codis和twemproxy最大的区别有两个：一个是codis支持动态水平扩展，对client完全透明不影响服务的情况下可以完成增减redis实例的操作；一个是codis是用go语言写的并支持多线程而twemproxy用C并只用单线程。 后者又意味着：codis在多核机器上的性能会好于twemproxy；codis的最坏响应时间可能会因为GC的STW而变大，不过go1.5发布后会显著降低STW的时间；如果只用一个CPU的话go语言的性能不如C，因此在一些短连接而非长连接的场景中，整个系统的瓶颈可能变成accept新tcp连接的速度，这时codis的性能可能会差于twemproxy。 ### 相对于redis cluster的优劣？ redis cluster基于smart client和无中心的设计，client必须按key的哈希将请求直接发送到对应的节点。这意味着：使用官方cluster必须要等对应语言的redis driver对cluster支持的开发和不断成熟；client不能直接像单机一样使用pipeline来提高效率，想同时执行多个请求来提速必须在client端自行实现异步逻辑。 而codis因其有中心节点、基于proxy的设计，对client来说可以像对单机redis一样去操作proxy（除了一些命令不支持），还可以继续使用pipeline并且如果后台redis有多个的话速度会显著快于单redis的pipeline。同时codis使用zookeeper来作为辅助，这意味着单纯对于redis集群来说需要额外的机器搭zk，不过对于很多已经在其他服务上用了zk的公司来说这不是问题：） ### Codis是如何分片的？ Codis 采用 Pre-sharding 的技术来实现数据的分片, 默认分成 1024 个 slots (0-1023), 对于每个key来说, 通过以下公式确定所属的 Slot Id : SlotId = crc32(key) % 1024。 每一个 slot 都会有一个且必须有一个特定的 server group id 来表示这个 slot 的数据由哪个 server group 来提供。数据的迁移也是以slot为单位的。 ### Codis 可以当队列使用吗? 可以, Codis 还是支持 LPUSH LPOP这样的指令, 但是注意, 并不是说你用了 Codis 就有了一个分布式队列. 对于单个 key, 它的 value 还是会在一台机器上, 所以, 如果你的队列特别大, 而且整个业务就用了几个 key, 那么就几乎退化成了单个 redis 了, 所以, 如果你是希望有一个队列服务, 那么我建议你: 1. List key 里存放的是任务id, 用另一个key-value pair来存放具体任务信息 2. 使用 Pull 而不是 Push, 由消费者主动拉取数据, 而不是生产者推送数据. 3. 监控好你的消费者, 当队列过长的时候, 及时报警. 4. 可以将一个大队列拆分成多个小的队列, 放在不同的key中 ### Codis 支持 MSET, MGET吗? 支持, 在比较早的版本中MSET/MGET的性能较差，甚至可能差过单机redis，但2.0开始会因为后台并发执行而比单机的mset/mget快很多。 ### Codis 是多线程的吗? 虽然Redis是单线程的，但Codis proxy 是多线程的(严格来说是 goroutine), 启动的线程数是 CPU 的核数, 是可以充分利用起多核的性能的。 ### Codis 支持 CAS 吗? 支持 Lua 脚本吗? CAS 暂时不支持, 目前只支持eval的方式来跑lua脚本，需要配合TAG使用. ### 有没有 zookeeper 的教程？ [请参考这里](http://www.juvenxu.com/2015/03/20/experiences-on-zookeeper-ops/) ### Codis的性能如何? 见Readme中的[Benchmark一节](https://github.com/CodisLabs/codis#performance-benchmark)。 ### 我的数据在 Codis 上是安全的吗? 首先, 安全的定义有很多个级别, Codis 并不是一个多副本的系统 (用纯内存来做多副本还是很贵的), 如果 Codis 底下的 redis 机器没有配从, 也没开 bgsave, 如果挂了, 那么最坏情况下会丢失这部分的数据, 但是集群的数据不会全失效 (即使这样的, 也比以前单点故障, 一下全丢的好...-_-|||). 如果上一种情况下配了从, 这种情况, 主挂了, 到从切上来这段时间, 客户端的部分写入会失败. 主从之前没来得及同步的小部分数据会丢失. 第二种情况, 业务短时间内爆炸性增长, 内存短时间内不可预见的暴涨(就和你用数据库磁盘满了一样), Codis还没来得及扩容, 同时数据迁移的速度小于暴涨的速度, 此时会触发 Redis 的 LRU 策略, 会淘汰老的 Key. 这种情况也是无解...不过按照现在的运维经验, 我们会尽量预分配一些 buffer, 内存使用量大概 80% 的时候, 我们就会开始扩容. 除此之外, 正常的数据迁移, 扩容缩容, 数据都是安全的. ### 你们如何保证数据迁移的过程中多个 Proxy 不会读到老的数据 (迁移的原子性) ? 见 [Codis 数据迁移流程](http://0xffff.me/blog/2014/11/11/codis-de-she-ji-yu-shi-xian-part-2/) ### Codis支持etcd吗 ? 支持，请参考使用教程，需要将配置文件中的coordinator=zookeeper改为etcd。 但是需要注意：请使用codis2.0.10或更新的版本，旧版对etcd的支持有一些问题；由于etcd在2.2引入了一个与旧版不兼容的坑爹改动，导致如果使用etcd的版本>=2.2.0，暂时需要手动改一处代码，详情见[相关issue](https://github.com/CodisLabs/codis/issues/488)。 ### 现有redis集群上有上T的数据，如何迁移到Codis上来？ 为了提高 Codis 推广和部署上的效率，我们为数据迁移提供了一个叫做 [redis-port](https://github.com/CodisLabs/redis-port) 的命令行工具，它能够： + 静态分析 RDB 文件，包括解析以及恢复 RDB 数据到 redis + 从 redis 上 dump RDB 文件以及从 redis 和 codis 之间动态同步数据 ### 如果需要迁移现有 redis 数据到 codis，该如何操作？ + 先搭建好 codis 集群并让 codis-proxy 正确运行起来 + 对线上每一个 redis 实例运行一个 redis-port 来向 codis 导入数据，例如： for port in {6379,6380,6479,6480}; do nohup redis-port sync --ncpu=4 --from=redis-server:${port} \ --target=codis-proxy:19000 > ${port}.log 2>&1 & sleep 5 done tail -f *.log - 每个 redis-port 负责将对应的 redis 数据导入到 codis - 多个 redis-port 之间不互相干扰，除非多个 redis 上的 key 本身出现冲突 - 单个 redis-port 可以将负责的数据并行迁移以提高速度，通过 --ncpu 来指定并行数 - 导入速度受带宽以及 codis-proxy 处理速度限制(本质是大量的 slotsrestore 操作) + 完成数据迁移，在适当的时候将服务指向 Codis，并将原 redis 下线 - 旧 redis 下线时，会导致 reids-port 链接断开，于是自动退出 ### redis-port 是如何在线迁移数据的？ + redis-port 本质是以 slave 的形式挂载到现有 redis 服务上去的 1. redis 会生成 RDB DUMP 文件给作为 slave 的 redis-port 2. redis-port 分析 RDB 文件，并拆分成 key-value 对，通过 [slotsrestore](https://github.com/CodisLabs/codis/blob/master/doc/redis_change_zh.md#slotsrestore-key1-ttl1-val1-key2-ttl2-val2-) 指令发给 codis 3. 迁移过程中发生的修改，redis 会将这些指令在 RDB DUMP 发送完成后，再发给 redis-port，而 redis-port 收到这些指令后不作处理，而直接转发给 Codis + redis-port 处理还是很快的，参考： - https://github.com/sripathikrishnan/redis-rdb-tools - https://github.com/cupcake/rdb ### Dashboard 中 Ops 一直是 0？ 检查你的启动 dashboard 进程的机器，看是否可以访问proxy的地址，对应的地址是 proxy 启动参数中的 debug_var_addr 中填写的地址。 ### zk: node already exists 无论是proxy还是dashboard，都会在zk上注册自己的节点，同时在程序正常退出的时候会删掉对应的节点，但如果异常退出或试用`kill -9 {pid}`就会导致zk的节点无法删除，在下一次启动的时候会报“zk: node already exists”的错误。 因此关闭服务的时候直接用`kill {pid}`不要-9，同时如果无法启动并且确认没有其他运行中的进程占用zk上的节点，可以在zk上手动删除/zk/codis/db_test/dashboard 或/zk/codis/db_test/fence/{host:port}. ### 编译报错 undefined: utils.Version 说明没有正确的设置go项目路径导致生成的文件找不到。见[安装教程](https://github.com/CodisLabs/codis/blob/master/doc/tutorial_zh.md#build-codis-proxy--codis-config)来正确配置环境变量并用正确的方式下载代码。 ### zk: session has been expired by the server 因为使用的go-zookeeper库代码注释里写的session超时时间参数单位是秒，但实际上该参数的单位是毫秒，所以<=2.0.7的版本错误的将默认配置设成30。因此请将配置文件修改为30000。此外2.0.8起如果配置文件中的参数过小则自动将秒转化为毫秒。 Codis的proxy会注册在zk上并监听新的zk事件。因为涉及到数据一致性的问题，所有proxy必须能尽快知道slot状态的改变，因此一旦和zk的连接出了问题就无法知道最新的slot信息从而可能不得不阻塞一些请求以防止数据错误或丢失。 Proxy会每几秒给zk发心跳，proxy的load太高可能导致timeout时间内（默认30秒，配置文件中可以修改）没有成功发心跳导致zk认为proxy已经挂了（当然也可能proxy确实挂了）， 这时如果client用了我们修改的Jedis, [Jodis](https://github.com/CodisLabs/jodis)，是会监控到zk节点上proxy少了一个从而自动避开请求这个proxy以保证客户端业务的可用性。如果用非Java语言可以根据Jodis代码DIY一个监听zk的客户端。 另外，如果需要异步请求，可以使用我们基于Netty开发的[Nedis](https://github.com/CodisLabs/nedis)。 当然，proxy收到session expired的错误也不意味着proxy一定要强制退出，但是这是最方便、安全的实现方式。而且实际使用中出现错误的情况通常是zk或proxy的load过高导致的，即使这时不退出可能业务的请求也会受影响，因此出现这个问题通常意味着需要加机器了。 如果不依赖zk/Jodis来做proxy的高可用性（虽然我们建议这样做），可以适当延长配置文件中的超时时间以降低出这个错误的概率。 ### proxy异常退出 目前proxy异常退出主要有两种可能，一种是zk的session expired错误，原因见前一节；另一种是从zk获取集群信息时超时或者报错。总体来说都是因为proxy和zk的连接不稳定导致的，而现在还没有加上重试等逻辑。 不过，最新版的codis已经可以实现proxy自动启动、自动标记为online。因此可以外部通过脚本或supervisor等服务来监控proxy的进程，一旦进程退出可以直接自动重启。 ================================================ FILE: doc/bench1/Makefile

================================================ FILE: doc/redis_change_zh.md ================================================ ### redis 修改部分（增加若干指令） -------------------------------- ##### SLOTSINFO [start] [count] + 命令说明：获取 redis 中 slot 的个数以及每个 slot 的大小 + 命令参数：缺省查询 [0, MAX\_SLOT\_NUM) - start - 起始的 slot 序号 缺省 = 0 - count - 查询的区间的大小，即查询范围为 [start, start + count) 缺省 = MAX\_SLOT\_NUM + 返回结果：返回结果是 slotinfo 的 array；slotinfo 本身也是一个 array。 response := []slotinfo{slot1, slot2, slot3, ...} slotinfo := []int{slotnum, slotsize} 其中： INT slotnum : slot 序号 INT slotsize : slot 内数据个数 + 例如： localhost:6379> slotsinfo 0 128 1) 1) (integer) 23 2) (integer) 2 2) 1) (integer) 29 2) (integer) 1 ##### SLOTSSCAN slotnum cursor [COUNT count] + 命令说明：获取指定 slotnum 下的 key 列表 + 命令参数：参数说明类似 SCAN 命令 - slotnum - 查询的 slot 序号，[0, MAX\_SLOT\_NUM） - cursor - 说明参考 SCAN 命令 - [COUNT count) - 说明参考 SCAN 命令 - 暂不支持 MATCH 查询 + 返回结果：参考 SCAN 命令 - 返回更新后的 cursor 以及一组 key 列表 + 例如: localhost:6379> slotsscan 579 0 COUNT 10 1) "10752" 2) 1) "{a}7836" 2) "{a}2167" 3) "{a}5332" 4) "{a}6292" 5) "{a}600" 6) "{a}6094" 7) "{a}7754" 8) "{a}4929" 9) "{a}9211" 10) "{a}6596" ##### SLOTSDEL slot1 [slot2 …] + 命令说明：删除 redis 中若干 slot 下的全部 key-value + 命令参数：接受至少 1 个 slotnum 作为参数 + 返回结果：格式参见 slotsinfo，不同的是：slotsize 表示删除后剩余大小，通常为 0。 + 例如： localhost:6379> slotsdel 1013 990 1) 1) (integer) 1013 2) (integer) 0 2) 1) (integer) 990 2) (integer) 0 #### 数据迁移 --------------- **以下4个命令是一族命令：** + SLOTSMGRTSLOT - *O(1)* 随机在某个 slot 下迁移一个 key-value 到目标机器 + SLOTSMGRTONE - *O(1)* 将指定的 key-value 迁移到目标机 + SLOTSMGRTTAGSLOT - *O(log(n))* 随机在某个 slot 下选择一个 key，并将与之有相同 tag 的 key-value 对全部迁移到目标机 + SLOTSMGRTTAGONE - *O(log(n))* 将与指定 key 具有相同 tag 的所有 key-value 对迁移到目标机 ##### SLOTSMGRTSLOT host port timeout slot + 命令说明：随机选择 slot 下的 1 个 key-value 到迁移到目标机（同步 IO 操作） - 如果当前 slot 已经空了或者选择的 key 刚好过期，返回 0 - 如果当前 slot 下面还有 key 则选择一个进行迁移 - 同时返回当前 slot 剩余 key 的个数 - 迁移过程在目标机器调用 slotsrestore 命令，迁移会 **覆盖旧值** + 命令参数： - host:port - 目标机 redis 内部缓存到 host:port 的连接 30s，超时或错误则关闭 - timeout - 操作超时，单位 ms 过程需要 3 个同步操作： 1. 建立连接（可被缓存优化） 2. 发送 key-value 数据 3. 接受目标机返回 指令保证每个操作不超过 timeout - slot - 指定迁移的 slot 序号 + 返回结果： 操作返回 int response := []int{succ,size} 其中： INT succ : 表示迁移是否成功。 0 表示当前 slot 已经空了（迁移成功个数=0） 1 表示迁移一个 key 成功，并从本地删除（迁移成功个数=1） INT size : 表示 slot 下剩余 key 的个数 + 例如： localhost:6379> set a 100 # set OK localhost:6379> slotsinfo # slot 大小为 1 1) 1)

a distributed Redis solution, there is no obvious difference between connecting to a Codis proxy and an original Redis server, top layer application can connect to Codis as normal standalone Redis, Codis will forward low layer requests. Hot data migration and all things in the shadow are transparent to client. Simply treat Codis as a Redis service with unlimited RAM. Codis 3.x consists of the following components: * **Codis Server**: based on redis-3.2.8 branch development. Added additional data structures to support slot-related operations and data migration instructions. Specific changes can refer to the document [redis changes](redis_change_zh.md). * **Codis Proxy**: is the proxy service of client connections. Codis Proxy Implements Redis Protocol. In addition to some commands do not support ([unsupported command list](unsupported_cmds.md)). + For the same product cluster, you can deploy multiple codis-proxy instances at the same time; + Different codis-proxy by codis-dashboard to ensure state synchronization. * **Codis Dashboard**: cluster management tools, support codis-proxy, codis-server add, delete, slot migrate(sync/async), and other operations. When a cluster state changes, the codis-dashboard maintains the consistency of all codis-proxy states under the cluster. + For the same product cluster, the same time codis-dashboard can only have 0 or 1; + All changes to the cluster must be done via codis-dashboard. * **Codis Admin**: Command-line tool for cluster management. + Can be used to control the codis-proxy, codis-dashboard status, and access external storage. * **Codis FE**: cluster management Web Interface. + Multiple cluster instances can share the same front-end display page; + FE reads all cluster instances name from external storage. * **Storage**: Provides external storage for cluster status, and saves cluster metadata. + Provide the concept of Namespace, different clusters will be organized according to different product name; + Currently only provides Zookeeper, Etcd, Fs three implementations, but provides an abstract interface can be self-expansion. ## Getting Codis ### Download Pre-built Release Binaries The easiest way to get codis is to use one of the pre-built release binaries which are available for OSX, Linux. Instructions for using these binaries are on the [GitHub releases page][github-release]. ### Compile Source Code For those wanting to try the very latest version, build the latest version of codis from the `master` branch. This first needs [*Go*](https://golang.org/) installed (version 1.7+ is required). All development occurs on `master`, including new features and bug fixes. Bug fixes are first targeted at `master` and subsequently ported to release branches. #### 1. Install Go Environment [reference](https://golang.org/doc/install) After the installation is complete, you can run the following command to detect： ```bash $ go version go version go1.7.3 linux/amd64 ``` #### 2. Set the compilation environment Add `$GOPATH/bin` To `$PATH`，For Example：`PATH=$PATH:$GOPATH/bin`。 ```bash $ go env GOPATH /home/codis/gopath ``` #### 3. Download Codis Source Code The Codis source code needs to be downloaded to `$GOPATH/src/github.com/CodisLabs/codis`： ```bash $ mkdir -p $GOPATH/src/github.com/CodisLabs $ cd $_ && git clone https://github.com/CodisLabs/codis.git -b release3.2 ``` #### 4. Compile Codis Source Code * use make tool to compile： ```bash $ cd $GOPATH/src/github.com/CodisLabs/codis $ make make -j -C extern/redis-3.2.8/ ... ... go build -i -o bin/codis-dashboard ./cmd/dashboard go build -i -o bin/codis-proxy ./cmd/proxy go build -i -o bin/codis-admin ./cmd/admin go build -i -o bin/codis-fe ./cmd/fe $ ls bin/ total 69124 drwxr-xr-x 4 codis codis 4096 Jan 4 14:55 assets -rwxr-xr-x 1 codis codis 17600752 Jan 4 14:55 codis-admin -rwxr-xr-x 1 codis codis 18416320 Jan 4 14:55 codis-dashboard -rwxr-xr-x 1 codis codis 9498040 Jan 4 14:55 codis-fe -rwxr-xr-x 1 codis codis 11057280 Jan 4 14:55 codis-proxy -rwxr-xr-x 1 codis codis 4234432 Jan 4 14:55 codis-server -rw-r--r-- 1 codis codis 148 Jan 4 14:55 version ... ... $ cat bin/version version = 2016-01-03 14:53:22 +0800 @51f06ae3b58a256a58f857f590430977638846a3 compile = 2016-01-04 15:00:17 +0800 by go version go1.5.2 linux/amd64 ``` ## Running Codis Cluster Build a standalone codis cluster in 2 minutes,without any external component dependencies. The admin folder in the source code provides a series of scripts to quickly start, stop the codis components, improve the efficiency of operation and maintenance. ### Start codis-dashboard Use codis-dashboard-admin.sh script to start dashboard and check the dashboard log to confirm whether there is an exception. ``` ./admin/codis-dashboard-admin.sh start tail -100 ./log/codis-dashboard.log.2017-04-08 ``` ``` 2017/04/08 15:16:57 fsclient.go:197: [INFO] fsclient - create /codis3/codis-demo/topom OK 2017/04/08 15:16:57 main.go:140: [WARN] [0xc42025f7a0] dashboard is working ... 2017/04/08 15:16:57 topom.go:424: [WARN] admin start service on [::]:18080 ``` The default external storage Uses filesystem, the default data path is saved in /tmp/codis. If the startup fails, please check whether the current user has read/write access to the path. ### Start codis-proxy Use codis-proxy-admin.sh script to start codis-proxy and check the proxy log to confirm whether there is an exception. ``` ./admin/codis-proxy-admin.sh start tail -100 ./log/codis-proxy.log.2017-04-08 ``` ``` 2017/04/08 15:39:37 proxy.go:293: [WARN] [0xc4200df760] set sentinels = [] 2017/04/08 15:39:37 main.go:320: [WARN] rpc online proxy seems OK 2017/04/08 15:39:38 main.go:210: [WARN] [0xc4200df760] proxy is working ... ``` ### Start codis-server Use codis-server-admin.sh script to start codis-server and check the redis log to confirm whether there is an exception. ``` ./admin/codis-server-admin.sh start tail -100 /tmp/redis_6379.log ``` ``` 5706:M 08 Apr 16:04:11.748 * DB loaded from disk: 0.000 seconds 5706:M 08 Apr 16:04:11.748 * The server is now ready to accept connections on port 6379 ``` redis.conf pidfile,logfile default saves in the /tmp directory. If the startup fails, please check whether the current user has read/write access to the path. ### Start codis-fe Use codis-fe-admin.sh script to start codis-fe and check the redis log to confirm whether there is an exception. ``` ./admin/codis-fe-admin.sh start tail -100 ./log/codis-fe.log.2017-04-08 ``` ``` 2017/04/08 16:12:13 main.go:100: [WARN] set ncpu = 1 2017/04/08 16:12:13 main.go:103: [WARN] set listen = 0.0.0.0:9090 2017/04/08 16:12:13 main.go:115: [WARN] set assets = /home/codis/go/src/github.com/CodisLabs/codis/admin/../bin/assets 2017/04/08 16:12:13 main.go:153: [WARN] set --filesystem = /tmp/codis ``` ### Add group by fe Please visit the cluster management web page(fe url:127.0.0.1:9090) Select the cluster(codis-demo) we have just built, in the Proxy column we can see that we have activated the Proxy, But the Group column is empty, because codis-server is not joined the cluster. Add NEW GROUP In the `NEW GROUP` row, please input a number such as 1, and click NEWGROUP Add Codis Server In the `Add Server` row, please input the codis-server address we just started, add it to GROUP, and then click the Add Server button, as shown below ![addgroup](pictures/addgroup.jpg) ### Initialize slot by fe The new cluster slot status is offline, so we need to initialize it (allocate 1024 slots to each group), and the fastest way to initialize a cluster is to click the `rebalance all slots` button provided by fe, as shown in the following figure. ![rebalance_slots](pictures/rebalance_slots.jpg) ## Quickly deploy the cluster by ansible Use ansible to quickly deploy multiple clusters in standalone and multi-machine environment. The ansible folder contains the playbook for deploying the codis cluster, modifying the parameters in the groups_var / all file according to your own deployment environment, and modifying the hosts file to add the deployed environment IP. Ansible installation is simple.Once Ansible is installed, there will be no daemons to start or keep running. You only need to install it on one machine and it can manage an entire fleet of remote machines from that central point. Ansible by default manages machines over the SSH protocol. ``` git clone https://github.com/ansible/ansible.git -b stable-2.3 cd ./ansible source ./hacking/env-setup cd $codis_dir/ansible ansible-playbook -i hosts site.yml ``` ## Codis HA Codis's proxy is stateless so you can run more than one proxies to get high availability and horizontal scalability. For Java users, you can use a modified Jedis, [Jodis](https://github.com/CodisLabs/jodis). It will watch the ZooKeeper to get the real-time available proxies, then query via them using a round robin policy to balance load and detect proxy online and offline automatically. If asynchronous request is required, you can use [Nedis](https://github.com/CodisLabs/nedis) which is implemented based on Netty. Codis-server is stateful.Redis Sentinel provides high availability for Codis-Server.Codis uses it to check master and slave instances are working as expected and start a failover process where a slave is promoted to master, the other additional slaves are reconfigured to use the new master. ================================================ FILE: doc/tutorial_zh.md ================================================ # Codis 使用文档 Codis 是一个分布式 Redis 解决方案, 对于上层的应用来说, 连接到 Codis Proxy 和连接原生的 Redis Server 没有显著区别 ([不支持的命令列表](unsupported_cmds.md)), 上层应用可以像使用单机的 Redis 一样使用, Codis 底层会处理请求的转发, 不停机的数据迁移等工作, 所有后边的一切事情, 对于前面的客户端来说是透明的, 可以简单的认为后边连接的是一个内存无限大的 Redis 服务。 ## codis版本简介 codis目前主要release版本如下: ### codis 1.9 > * codis-server 基于 redis-2.8.13 > * codis-proxy 对 pipeline 支持不友好 > * codis-proxy 对 zk 强依赖 > * 同步迁移性能差，不支持大 key 迁移 ### codis 2.0 > * codis-server 基于 redis-2.8.21 > * 重构了codis-proxy，性能大幅提升，对 pipeline 支持比较好 > * codis-proxy 对 zk 强依赖 > * 同步迁移性能差，不支持大key迁移 ### codis 3.x > * 最新 release 版本为 codis-3.2，codis-server 基于 redis-3.2.8 > * 支持 slot 同步迁移、异步迁移和并发迁移，对 key 大小无任何限制，迁移性能大幅度提升 > * 相比 2.0：重构了整个集群组件通信方式，codis-proxy 与 zookeeper 实现了解耦，废弃了codis-config 等 > * 元数据存储支持 etcd/zookeeper/filesystem 等，可自行扩展支持新的存储，集群正常运行期间，即便元存储故障也不再影响 codis 集群，大大提升 codis-proxy 稳定性 > * 对 codis-proxy 进行了大量性能优化,通过控制GC频率、减少对象创建、内存预分配、引入 `cgo`、`jemalloc` 等，使其吞吐还是延迟，都已达到 codis 项目中最佳 > * proxy 实现 select 命令，支持多 DB > * proxy 支持读写分离、优先读同 IP/同 DC 下副本功能 > * 基于 redis-sentinel 实现主备自动切换 > * 实现动态 pipeline 缓存区（减少内存分配以及所引起的 GC 问题） > * proxy 支持通过 HTTP 请求实时获取 runtime metrics，便于监控、运维 > * 支持通过 influxdb 和 statsd 采集 proxy metrics > * slot auto rebalance 算法从 2.0 的基于 max memory policy 变更成基于 group 下 slot 数量 > * 提供了更加友好的 dashboard 和 fe 界面，新增了很多按钮、跳转链接、错误状态等，有利于快速发现、处理集群故障 > * 新增 `SLOTSSCAN` 指令，便于获取集群各个 slot 下的所有 key > * codis-proxy 与 codis-dashbaord 支持 docker 部署 Codis 3.x 由以下组件组成： * **Codis Server**：基于 redis-3.2.8 分支开发。增加了额外的数据结构，以支持 slot 有关的操作以及数据迁移指令。具体的修改可以参考文档 [redis 的修改](redis_change_zh.md)。 * **Codis Proxy**：客户端连接的 Redis 代理服务, 实现了 Redis 协议。 除部分命令不支持以外([不支持的命令列表](unsupported_cmds.md))，表现的和原生的 Redis 没有区别（就像 Twemproxy）。 + 对于同一个业务集群而言，可以同时部署多个 codis-proxy 实例； + 不同 codis-proxy 之间由 codis-dashboard 保证状态同步。 * **Codis Dashboard**：集群管理工具，支持 codis-proxy、codis-server 的添加、删除，以及据迁移等操作。在集群状态发生改变时，codis-dashboard 维护集群下所有 codis-proxy 的状态的一致性。 + 对于同一个业务集群而言，同一个时刻 codis-dashboard 只能有 0个或者1个； + 所有对集群的修改都必须通过 codis-dashboard 完成。 * **Codis Admin**：集群管理的命令行工具。 + 可用于控制 codis-proxy、codis-dashboard 状态以及访问外部存储。 * **Codis FE**：集群管理界面。 + 多个集群实例共享可以共享同一个前端展示页面； + 通过配置文件管理后端 codis-dashboard 列表，配置文件可自动更新。 * **Storage**：为集群状态提供外部存储。 + 提供 Namespace 概念，不同集群的会按照不同 product name 进行组织； + 目前仅提供了 Zookeeper、Etcd、Fs 三种实现，但是提供了抽象的 interface 可自行扩展。 ## 0. 下载与编译 ### 下载[release binary](https://github.com/CodisLabs/codis/releases)文件安装 如果是重要的生产环境使用，尽量不要选择alpha、rc版本。 根据自己的部署平台，选择相应的文件下载即可。 ### 编译源码安装 #### 1. 安装 Go 运行环境 [参考这里](https://golang.org/doc/install) 安装完成后可以运行下列命令进行检测： ```bash $ go version go version go1.7.3 linux/amd64 ``` #### 2. 设置编译环境 **注意 `$GOPATH` 是本机所有第三方库 go 项目所在目录，Codis 仅是其中之一。** 添加 `$GOPATH/bin` 到 `$PATH`，例如：`PATH=$PATH:$GOPATH/bin`。 ```bash $ go env GOPATH /home/codis/gopath ``` #### 3. 下载 Codis 源代码 Codis 源代码需要下载到 `$GOPATH/src/github.com/CodisLabs/codis`： ```bash $ mkdir -p $GOPATH/src/github.com/CodisLabs $ cd $_ && git clone https://github.com/CodisLabs/codis.git -b release3.2 ``` #### 4. 编译 Codis 源代码 * 直接通过 make 进行编译，会看到如下输出： ```bash $ cd $GOPATH/src/github.com/CodisLabs/codis $ make make -j -C extern/redis-3.2.8/ ... ... go build -i -o bin/codis-dashboard ./cmd/dashboard go build -i -o bin/codis-proxy ./cmd/proxy go build -i -o bin/codis-admin ./cmd/admin go build -i -o bin/codis-fe ./cmd/fe $ ls bin/ total 69124 drwxr-xr-x 4 codis codis 4096 Jan 4 14:55 assets -rwxr-xr-x 1 codis codis 17600752 Jan 4 14:55 codis-admin -rwxr-xr-x 1 codis codis 18416320 Jan 4 14:55 codis-dashboard -rwxr-xr-x 1 codis codis 9498040 Jan 4 14:55 codis-fe -rwxr-xr-x 1 codis codis 11057280 Jan 4 14:55 codis-proxy -rwxr-xr-x 1 codis codis 4234432 Jan 4 14:55 codis-server -rw-r--r-- 1 codis codis 148 Jan 4 14:55 version ... ... $ cat bin/version version = 2016-01-03 14:53:22 +0800 @51f06ae3b58a256a58f857f590430977638846a3 compile = 2016-01-04 15:00:17 +0800 by go version go1.5.2 linux/amd64 ``` ## 1. 快速启动 2分钟快速构建一个单机版测试 codis 集群，无任何外部组件依赖. 源码中 admin 文件夹提供了一系列脚本以便快速启动、停止各个组件，提高运维效率。 ### 启动codis-dashboard 使用 `codis-dashboard-admin.sh` 脚本启动 dashboard，并查看 dashboard 日志确认启动是否有异常。 ``` ./admin/codis-dashboard-admin.sh start tail -100 ./log/codis-dashboard.log.2017-04-08 ``` ``` 2017/04/08 15:16:57 fsclient.go:197: [INFO] fsclient - create /codis3/codis-demo/topom OK 2017/04/08 15:16:57 main.go:140: [WARN] [0xc42025f7a0] dashboard is working ... 2017/04/08 15:16:57 topom.go:424: [WARN] admin start service on [::]:18080 ``` 快速启动集群元数据存储使用 `filesystem`，默认数据路径保存在 `/tmp/codis`，若启动失败，请检查当前用户是否对该路径拥有读写权限。 ### 启动codis-proxy 使用 `codis-proxy-admin.sh` 脚本启动 codis-proxy，并查看 proxy 日志确认启动是否有异常。 ``` ./admin/codis-proxy-admin.sh start tail -100 ./log/codis-proxy.log.2017-04-08 ``` ``` 2017/04/08 15:39:37 proxy.go:293: [WARN] [0xc4200df760] set sentinels = [] 2017/04/08 15:39:37 main.go:320: [WARN] rpc online proxy seems OK 2017/04/08 15:39:38 main.go:210: [WARN] [0xc4200df760] proxy is working ... ``` ### 启动codis-server 使用 `codis-server-admin.sh` 脚本启动 codis-server，并查看 redis 日志确认启动是否有异常。 ``` ./admin/codis-server-admin.sh start tail -100 /tmp/redis_6379.log ``` ``` 5706:M 08 Apr 16:04:11.748 * DB loaded from disk: 0.000 seconds 5706:M 08 Apr 16:04:11.748 * The server is now ready to accept connections on port 6379 ``` redis.conf 配置中 pidfile、logfile 默认保存在 `/tmp` 目录，若启动失败，请检查当前用户是否有该目录的读写权限。 ### 启动codis-fe 使用 `codis-fe-admin.sh` 脚本启动 codis-fe，并查看 fe 日志确认启动是否有异常。 ``` ./admin/codis-fe-admin.sh start tail -100 ./log/codis-fe.log.2017-04-08 ``` ``` 2017/04/08 16:12:13 main.go:100: [WARN] set ncpu = 1 2017/04/08 16:12:13 main.go:103: [WARN] set listen = 0.0.0.0:9090 2017/04/08 16:12:13 main.go:115: [WARN] set assets = /home/codis/go/src/github.com/CodisLabs/codis/admin/../bin/assets 2017/04/08 16:12:13 main.go:153: [WARN] set --filesystem = /tmp/codis ``` ### 通过fe添加group 通过web浏览器访问集群管理页面(fe地址:127.0.0.1:9090) 选择我们刚搭建的集群 codis-demo，在 Proxy 栏可看到我们已经启动的 Proxy， 但是 Group 栏为空，因为我们启动的 codis-server 并未加入到集群 添加 `NEW GROUP`，`NEW GROUP` 行输入 1，再点击 `NEW GROUP` 即可 添加 Codis Server，`Add Server` 行输入我们刚刚启动的 codis-server 地址，添加到我们刚新建的 Group，然后再点击 `Add Server` 按钮即可，如下图所示 ![addgroup](pictures/addgroup.jpg) ### 通过fe初始化slot 新增的集群 slot 状态是 offline，因此我们需要对它进行初始化（将 1024 个 slot 分配到各个 group），而初始化最快的方法可通过 fe 提供的 `rebalance all slots` 按钮来做，如下图所示，点击此按钮，我们即快速完成了一个集群的搭建。 ![rebalance_slots](pictures/rebalance_slots.jpg) ## 通过 ansible 快速部署集群 使用 ansible 可快速在单机、多机部署多套 codis 集群。 ansible 文件夹包含了部署 codis 集群的 playbook，根据自己部署环境修改 `groups_var/all` 文件里参数，修改 hosts 文件添加部署的环境 IP 即可。 ansible 安装也及其简单，各部署机器无需安装任何额外的 agent，彼此之间通过 ssh 通信。 ``` git clone https://github.com/ansible/ansible.git -b stable-2.3 cd ./ansible source ./hacking/env-setup cd $codis_dir/ansible ansible-playbook -i hosts site.yml ``` ## 2. 启动及参数 **注意：请按照顺序逐步完成操作。生产环境建议修改dashboard coordinator_name配置，使用 `zookeeper` 或`etctd`作为外部存储。** **注意：Codis 3.x 支持 AUTH，但是要求所有组件使用的 AUTH 必须完全相同。** #### 2.1 Codis Dashboard ##### 2.1.1 启动命令： ```bash $ nohup ./bin/codis-dashboard --ncpu=4 --config=dashboard.toml \ --log=dashboard.log --log-level=WARN & ``` 默认配置文件 `dashboard.toml` 可由 codis-dashboard 生成。 ##### 2.1.2 详细说明： + 启动参数说明： ```bash $ ./bin/codis-dashboard -h Usage: codis-dashboard [--ncpu=N] [--config=CONF] [--log=FILE] [--log-level=LEVEL] [--host-admin=ADDR] codis-dashboard --default-config codis-dashboard --version Options: --ncpu=N 最大使用 CPU 个数 -c CONF, --config=CONF 指定启动配置文件 -l FILE, --log=FILE 设置 log 输出文件 --log-level=LEVEL 设置 log 输出等级：INFO,WARN,DEBUG,ERROR；默认INFO，推荐WARN ``` 参数 `--host-admin` 请参见与 Docker 有关章节。 + 默认配置文件： ```bash $ ./bin/codis-dashboard --default-config | tee dashboard.toml ################################################## # # # Codis-Dashboard # # # ################################################## # Set Coordinator, only accept "zookeeper" & "etcd" coordinator_name = "zookeeper" coordinator_addr = "127.0.0.1:2181" # Set Codis Product {Name/Auth}. product_name = "codis-demo" product_auth = "" # Set bind address for admin(rpc), tcp only. admin_addr = "0.0.0.0:18080" ``` | 参数 | 说明 | |:----------------- |:---------------------------------- | | coordinator\_name | 外部存储类型，接受 zookeeper/etcd | | coordinator\_addr | 外部存储地址 | | product\_name | 集群名称，满足正则 `\w[\w\.\-]*` | | product\_auth | 集群密码，默认为空 | | admin\_addr | RESTful API 端口 | #### 2.2 Codis Proxy ##### 2.2.1 启动命令： ```bash $ nohup ./bin/codis-proxy --ncpu=4 --config=proxy.toml \ --log=proxy.log --log-level=WARN & ``` 默认配置文件 `proxy.toml` 可由 codis-proxy 生成。 codis-proxy 启动后，处于 `waiting` 状态，监听 `proxy_addr` 地址，但是不会 `accept` 连接，添加到集群并完成集群状态的同步，才能改变状态为 `online`。添加的方法有以下两种： + 通过 codis-fe 添加：通过 `Add Proxy` 按钮，将 `admin_addr` 加入到集群中； + 通过 codis-admin 命令行工具添加，方法如下： ```bash $ ./bin/codis-admin --dashboard=127.0.0.1:18080 --create-proxy -x 127.0.0.1:11080 ``` 其中 `127.0.0.1:18080` 以及 `127.0.0.1:11080` 分别为 dashboard 和 proxy 的 `admin_addr` 地址； 添加过程中，dashboard 会完成如下一系列动作： + 获取 proxy 信息，对集群 name 以及 auth 进行验证，并将其信息写入到外部存储中； + 同步 slots 状态； + 标记 proxy 状态为 `online`，此后 proxy 开始 `accept` 连接并开始提供服务； ##### 2.2.2 详细说明： + 启动参数说明： ```bash $ ./bin/codis-proxy -h Usage: codis-proxy [--ncpu=N] [--config=CONF] [--log=FILE] [--log-level=LEVEL] [--host-admin=ADDR] [--host-proxy=ADDR] [--ulimit=NLIMIT] codis-proxy --default-config codis-proxy --version Options: --ncpu=N 最大使用 CPU 个数 -c CONF, --config=CONF 指定启动配置文件 -l FILE, --log=FILE 设置 log 输出文件 --log-level=LEVEL 设置 log 输出等级：INFO,WARN,DEBUG,ERROR；默认INFO，推荐WARN --ulimit=NLIMIT 检查 ulimit -n 的结果，确保运行时最大文件描述不少于 NLIMIT ``` 参数 `--host-proxy` 以及 `--host-admin` 请参见与 Docker 有关章节。 + 默认配置文件： ```bash $ ./bin/codis-proxy --default-config | tee proxy.toml ################################################## # # # Codis-Proxy # # # ################################################## # Set Codis Product {Name/Auth}. product_name = "codis-demo" product_auth = "" # Set bind address for admin(rpc), tcp only. admin_addr = "0.0.0.0:11080" # Set bind address for proxy, proto_type can be "tcp", "tcp4", "tcp6", "unix" or "unixpacket". proto_type = "tcp4" proxy_addr = "0.0.0.0:19000" # Set jodis address & session timeout. jodis_addr = "" jodis_timeout = 10 jodis_compatible = false # Proxy will ping-pong backend redis periodly to keep-alive backend_ping_period = 5 # If there is no request from client for a long time, the connection will be droped.

Jodis 与 HA 因为 codis-proxy 是无状态的，可以比较容易的搭多个实例，达到高可用性和横向扩展。 对 Java 用户来说，可以使用基于 Jedis 的实现 [Jodis](https://github.com/CodisLabs/jodis) ，来实现 proxy 层的 HA： + 它会通过监控 zookeeper 上的注册信息来实时获得当前可用的 proxy 列表，既可以保证高可用性； + 也可以通过轮流请求所有的proxy实现负载均衡。 如果需要异步请求，可以使用我们基于Netty开发的 [Nedis](https://github.com/CodisLabs/nedis)。 对下层的 redis 实例来说，当一个 group 的 master 挂掉的时候，应该让管理员清楚，并手动的操作，因为这涉及到了数据一致性等问题（redis的主从同步是最终一致性的）。因此 codis 不会自动的将某个 slave 升级成 master。关于外部 codis-ha 工具（具体可以参考之前的章节），这是一个通过 codis-dashboard 开放的 RESTful API 实现自动切换主从的工具。该工具会在检测到 master 挂掉的时候主动应用主从切换策略，提升单个 slave 成为新的 master。 需要注意，codis 将其中一个 slave 升级为 master 时，该组内其他 slave 实例是不会自动改变状态的，这些 slave 仍将试图从旧的 master 上同步数据，因而会导致组内新的 master 和其他 slave 之间的数据不一致。因此当出现主从切换时，需要管理员手动创建新的 sync action 来完成新 master 与 slave 之间的数据同步（codis-ha 不提供自动操作的工具，因为这样太不安全了）。 ## 4. Docker 部署 Codis 3.x 起，开始正式支持 Docker 部署。这就需要 codis-dashboard 以及 codis-proxy 能够外部的 `listen` 地址暴露出来并保存在外部存储中。 + codis-proxy 增加了 `--host-admin` 以及 `--host-proxy` 参数； + codis-dashboard 增加了 `--host-admin` 参数； 以 codis-proxy 的 Docker 为例： ```bash $ docker run --name "Codis-Proxy" -d -p 29000:19000 -p 21080:11080 codis-image \ codis-proxy -c proxy.toml --host-admin 100.0.1.100:29000 --host-proxy 100.0.1.100:21080 ``` codis-proxy 在启动后，会使用 `--host-admin` 和 `--host-proxy` 参数所指定的实际地址替换 Docker 内监听的地址，向 codis-dashboard 注册。这样，例如使用 Jodis 的过程中，客户端就能够通过 `100.0.1.100:29000` 来访问 proxy 实例。 codis-dashboard 也是相同的道理，会使用 `--host-admin` 地址向外部存储注册，这样 codis-fe 也能通过该地址正确的对 codis-dashboard 进行操作。 具体样例可以参考 `scripts/docker.sh`。 ## 5. 从Codis 2.x 升级 Codis 3.x 修改了 codis-dashboard 与 codis-proxy 之间的通信方式，因此 Codis 2.x 并不兼容。但是我们提供了手动升级方案。 **注意1：升级时，需要保证所有 slot 都处在 `online` 状态。即没有任何数据迁移操作正在进行。** **注意2：升级完成后，需要手动关闭 Codis 2.x 的所有 proxy 和 config 组件。** #### step 1. 导出配置文件 ```bash $ ./bin/codis-admin --config-dump --product=codis_v2.0 --zookeeper=127.0.0.1:2181 -1 | tee codis_v2.0.json ``` 该命令会从 zookeeper 上拉取 `/zk/codis/db_codis_v2.0` 下全部的文件，并组织成 json 格式并输出。 选项 `-1` 表示配置文件是 Codis 1.x 版本，缺省是 Codis 3.x 版本。 #### step 2. 转换配置文件 ```bash $ ./bin/codis-admin --config-convert codis_v2.0.json | tee codis_v3.0.json ``` 该命令会将 Codis 1.x 版本的配置文件中有效信息提取出来，并转成 Codis 3.x 版本的配置文件并输出。 #### step 3. 更新配置文件 **注意：更新配置文件时，请确保 Codis 3.x 中该集群不存在，否则可能导致更新失败或者集群状态异常。** ```bash $ ./bin/codis-admin --config-restore=codis_v3.0.json --product=codis_v3.0 --zookeeper=127.0.0.1:2181 --confirm ``` 该命令会将 Codis 3.x 版本的配置文件提交到 `/codis3/codis_v3.0` 目录下。 选项 `--confirm` 选项表示确认提交，缺省时该命令仅仅打印配置文件作为调试。 #### step 4. 启动 Codis 3.x dashboard 以及 proxy 过程参考之前章节。因为集群信息已经存在，所以可以安全启动 codis-dashboard，并逐一添加 codis-proxy 到集群中。 #### step 5. 关闭 Codis 2.x dashboard 以及 proxy Codis 3.x 的组件兼容 Jodis 协议。 因为 Codis 2.x 与 Codis 3.x 在外部存储中的组织结构不同，所以可以安全的 `kill` 掉全部 Codis 2.x 组件。 **注意：关闭过程请不要使用 `kill -9`，因为旧组件在退出时会自动清理部分注册信息。** ================================================ FILE: doc/unsupported_cmds.md ================================================ These commands are disallowed in codis proxy, if you use them, proxy will close the connection to warn you. | Command Type | Command Name | |:----------------:|:---------------- | | Keys | KEYS | | | MIGRATE | | | MOVE | | | OBJECT | | | RANDOMKEY | | | RENAME | | | RENAMENX | | | SCAN | | | | | Strings | BITOP | | | MSETNX | | | | | Lists | BLPOP | | | BRPOP | | | BRPOPLPUSH | | | | | Pub/Sub | PSUBSCRIBE | | | PUBLISH | | | PUNSUBSCRIBE | | | SUBSCRIBE | | | UNSUBSCRIBE | | | | | Transactions | DISCARD | | | EXEC | | | MULTI | | | UNWATCH | | | WATCH | | | | | Scripting | SCRIPT | | | | | Server | BGREWRITEAOF | | | BGSAVE | | | CLIENT | | | CONFIG | | | DBSIZE | | | DEBUG | | | FLUSHALL | | | FLUSHDB | | | LASTSAVE | | | LATENCY | | | MONITOR | | | PSYNC | | | REPLCONF | | | RESTORE | | | SAVE | | | SHUTDOWN | | | SLAVEOF | | | SLOWLOG | | | SYNC | | | TIME | | | | | Codis Slot | SLOTSCHECK | | | SLOTSDEL | | | SLOTSINFO | | | SLOTSMGRTONE | | | SLOTSMGRTSLOT | | | SLOTSMGRTTAGONE | | | SLOTSMGRTTAGSLOT | These commands is "half-supported".

Codis does not check if the keys have same tag, so if you don't use tag, your program will get wrong response. | Command Type | Command Name | |:----------------:|:---------------- | | Lists |

(antirez) --[ Redis 2.8.18 ] Release date: 4 Dec 2014 # UPGRADE URGENCY: LOW for both Redis and Sentinel. This release mostly adds new features to Redis, and contains non critical fixes. * [FIX] Linenoise updated to be more VT100 compatible. (Salvatore Sanfilippo) * [FIX] A number of typos fixed inside comments. (Various authors) * [FIX] redis-cli no longer quits after long timeouts. (Matt Stancliff) * [FIX] Test framework improved to detect never terminating scripts, cleanup instances on crashes. (Salvatore Sanfilippo) * [FIX] PFCOUNT can be used on slaves now. (Salvatore Sanfilippo) * [FIX] ZSCAN no longer report very small scores as 0. (Matt Stancliff, Michael Grunder, Salvatore Sanfilippo) * [FIX] Don't show the ASCII logo if syslog is enabled. Redis is now an Enterprise Grade product. (Salvatore Sanfilippo) * [NEW] EXPERIMENTAL: Diskless replication, for more info check the doc at http://redis.io/topics/replication. (Salvatore Sanfilippo). * [NEW] Transparent Huge Pages detection and reporting in logs and LATENCY DOCTOR output. (Salvatore Sanfilippo) * [NEW] Many Lua scripting enhancements: Bitops API, cjson upgrade and tests, cmsgpack upgrade. (Matt Stancliff) * [NEW] Total and instantaneous Network bandwidth tracking in INFO. * [NEW] DEBUG POPULATE two args form implemented (old form still works). The second argument is the key prefix. Default is "key:" (Salvatore Sanfilippo) * [NEW] Check that tcp-backlog is matched by /proc/sys/net/core/somaxconn, and warn about it if not. (Salvatore Sanfilippo) --[ Redis 2.8.17 ] Release date: 19 Sep 2014 # UPGRADE URGENCY: HIGH for Redis Sentinel. LOW for Redis Server (unmodified compared to 2.8.16). * [FIX] Resolved a memory leak in the hiredis library causing a memory leak in Redis Sentinel when a monitored instance or another Sentinel is unavailable. Every reconnection attempt will leak a small amount of memory, but in the long run the process can reach a considerable size. --[ Redis 2.8.16 ] Release date: 16 Sep 2014 # UPGRADE URGENCY: HIGH for Redis if you are using 2.8.15 + AOF. LOW for Sentinel. * [FIX] The ability to load truncated AOF files introduced with Redis 2.8.15 contains a bug fixed in this release: after loading the file was not truncated to the last valid command, so the new commands are appended after a non well formed command. This means that: 1) The first AOF rewrite triggered by the server will automatically fix the problem. 2) However, if the server is restarted before the rewrite, Redis may not be able to load the file and you need to manually fix it. In order to fix a corrupted file you should start the redis-check-aof utility WITHOUT the --fix option, just to check the offset where the corruption is found. Around the offset reported by the check utility you'll find, inside your AOF file, a command which is not complete according to the Redis protocol. Just remove this incomplete command leafing the file unaltered before and after the offending command, and restart the server. IMPORTANT #1: Redis 2.8.15 is the only stable version of Redis with this bug so probably no actual real-world problem happened since the problem is automatically fixed at the first automatic AOF rewrite. IMPORTANT #2: Before upgrading to Redis 2.8.16, if you are using Redis 2.8.15 with AOF enabled, make sure to trigger a manual AOF rewrite using the BGREWRITEAOF command. * [FIX] SAVE is no longer propagated to AOF / slaves. --[ Redis 2.8.15 ] Release date: 12 Sep 2014 # UPGRADE URGENCY: LOW for Redis, HIGH for Sentinel. * [FIX] Sentinel critical bug fixed: the absolute majority was computed in a wrong way because of a programming error. Now the implementation does what the specification says and the majority to authorize a failover (that should not be confused with the ODOWN quorum) is the majority of *all* the Sentinels ever seen for a given master, regardless of their current state. * [FIX] GETRANGE test no longer fails for 32 bit builds (Matt Stancliff). * [FIX] Limit SCAN latency when the hash table is in an odd state (very few populted buckets because rehashing is in progress). (Xiaost and Salvatore Sanfilippo) * [NEW] Redis is now able to load truncated AOF files without requiring a redis-check-aof utility run. The default now is to load truncated (but apparently not corrupted) AOFs, you can change this in redis.conf. (Salvatore Sanfilippo). * [NEW] Sentinel: ability to announce itself with an arbitrary IP/port to work in the context of natted networks. However this is probably still not enough since there is no equivalent mechanism for slaves listed in the master INFO output. (Dara Kong and Salvatore Sanfilippo) --[ Redis 2.8.14 ] Release date: 1 Sep 2014 # UPGRADE URGENCY: HIGH for Lua scripting users, the server could crash because of a bug introduced in Redis 2.8.10, otherwise LOW. LOW for Redis Sentinel. * [FIX] Don't prevent use of shared integers if maxmemory policy is non-LRU. (Salvatore Sanfilippo) * [FIX] Fail SYNC if background save child aborted due to a signal. (Yossi Gottlieb) * [FIX] Different small redis-cli fixes. (Dov Murik, Charsyam, cubicdaiya, Kashif Rasul, Jan-Erik Rediger, Matt Stancliff) * [FIX] AIX compilation fixes. (Siah Lyimo) * [FIX] A number of other smaller issues. * [FIX] Improved SIGINT handling (Matt Stancliff, Salvatore Sanfilippo) * [FIX] Use unsigned types in SDS header to raise limit to 4GB. (Matt Stancliff, Salvatore Sanfilippo) * [FIX] Handle signed/unsigned comparisons with more care around the code. (Salvatore Sanfilippo) * [FIX] Colorized test output fixed to don't change the background color. (Mariano Pérez Rodríguez) * [FIX] More Sentinel IPv6 fixes. (Eiichi Sato) * [FIX] Deny CLIENT command in scripts. (Matt Stancliff) * [FIX] Allow datasets with more than 2 billion of keys, initial work. * [FIX] Fix a Lua scripting crash by storing the length of the static argv when first allocated. (Paddy Byers) * [NEW] Pub/Sub PING. (Salvatore Sanfilippo) * [NEW] Much faster ZUNIONSTORE. (Kyle Hubert, Salvatore Sanfilippo) * [NEW] Faster ll2string() implementation. (Salvatore Sanfilippo) * [NEW] **WARNING, minor API change**: PUBSUB NUMSUB: return type modified to integer. (Matt Stancliff) * [NEW] redis-benchmark support for AUTH. (CharSyam) --[ Redis 2.8.13 ] Release date: 14 Jul 2014 # UPGRADE URGENCY: LOW for Redis and Sentinel, this is a features enhancement release mostly. Since this release introduces the latency monitoring feature, Redis 2.8 users experiencing latency issues are strongly encouraged to upgrade. * [FIX] CLIENT KILL minor backward compatibility fixes. (Salvatore Sanfilippo) * [FIX] Enable HAVE_ATOMIC for PowerPC. (Matt Stancliff) * [FIX] More robust PSYNC and AOF rewrites tests. (Salvatore Sanfilippo) * [FIX] Solaris build fixed. (Matt Stancliff, Salvatore Sanfilippo) * [NEW] The new latency monitoring feature, as documented at http://redis.io/topics/latency-monitor (Salvatore Sanfilippo) * [NEW] The COMMAND command, exposing the Redis command table as an API. (Matt Stancliff) * [NEW] Update used memory with C11 __atomic. (Matt Stancliff) --[ Redis 2.8.12 ] Release date: 23 Jun 2014 # UPGRADE URGENCY: HIGH for Redis, CRITICAL for Sentinel. # WARNING: This release contains a non backward compatible semantical change to Lua script that should affect an almost zero number of users. * [FIX / BREAKS BACKWARD COMPATIBILITY] Using SELECT inside Lua scripts no longer makes the selected DB to be set in the calling client. So Lua can still use SELECT, but the client calling the script will remain set to the original DB. Thix fixes an issue with Redis replication of Lua scripts that called SELECT without reverting the selected DB to the original one. (Salvatore Sanfilippo) * [FIX] Sentinel failover was instalbe if the master was detected as available during the failover (especially during manual failovers) because of an implementation error (lack of checking of SRI_PROMOTED flag). (Salvatore Sanfilippo) * [FIX] Cancel SHUTDOWN if initial AOF is being written. (Matt Stancliff) * [FIX] Sentinel: bind source address for outcoming connections. (Matt Stancliff). * [FIX] Less timing sensitive Sentinel tests. (Salvatore Sanfilippo). * [NEW] redis-cli --intrinsic-latency stopped with SIGINT still reports stats (Matt Stancliff) * [NEW] Sentinels broadcast an HELLO message ASAP after a failover in order to reach a consistent state faster (before it relied for periodic HELLO messages). (Salvatore Sanfilippo). * [NEW] Jemalloc updated to 3.6.0. (Salvatore Sanfilippo) * [NEW] CLIENT LIST speedup. (Salvatore Sanfilippo) * [NEW] CLIENT LIST new unique incremental ID to every client. (Salvatore Sanfilippo) * [NEW] ROLE command added. (Salvatore Sanfilippo) * [NEW] CLIENT KILL new form to kill by client type and ID (see doc at redis.io for more info). (Salvatore Sanfilippo) * [NEW] Sentinel now disconnects clients when instances are reconfigured (see http://redis.io/topics/sentinel-clients). (Salvatore Sanfilippo) * [NEW] Hiredis update to latest version. (Matt Stancliff) --[ Redis 2.8.11 ] Release date: 11 Jun 2014 # UPGRADE URGENCY: HIGH if you use Lua scripting, LOW otherwise. * [FIX] A previous fix for Lua -> Redis numerical precision enhancement introduced a new problem. In Redis 2.8.10 commands called from Lua passing a string that "looks like" a very large number, may actually use as argument the string converted as a float. This bug is now fixed. * [FIX] Now commands other than *PUSH* adding elements to a list will be able to awake clients blocked in a blocking POP operation. * [FIX] Cygwin compilation fixes. --[ Redis 2.8.10 ] Release date: 5 Jun 2014 # UPGRADE URGENCY: HIGH if you use min-slaves-to-write option. * [FIX] IMPORTANT! A min-slaves-to-write option active in a slave totally prevented the slave from acception the master stream of commands. This release includes testes for min-slaves-to-write, and a fix for this issue. * [FIX] Sometimes DEL returned 1 for already expired keys. Fixed. * [FIX] Fix test false positive because new osx 'leaks' output. * [FIX] PFCOUNT HLL cache invalidation fixed: no wrong value was reported but the cache was not used at all, leading to lower performances. * [FIX] Accept(2) multiple clients per readable-event invocation, and better processing of I/O while loading or busy running a timedout script. Basically now the LOADING / BUSY errors are reported at a decent speed. * [FIX] A softwaer watchdog crash fixed. * [FIX] Fixed a Lua -> Redis numerical precision loss. * [NEW] Lua scripting engine speed improved. * [NEW] Sentinel generates one new event for humans to understand better what is happening during a failover: +config-update-from. Also the time at which a failover will be re-attempted is logged. --[ Redis 2.8.9 ] Release date: 22 Apr 2014 # UPGRADE URGENCY: LOW, only new features introduced, no bugs fixed. * [NEW] The HyperLogLog data structure. You can read more about it in this blog post. http://antirez.com/news/75 * [NEW] The Sorted Set data type has now support for lexicographic range queries, check the new commands ZRANGEBYLEX, ZLEXCOUNT and ZREMRANGEBYLEX, which are documented at http://redis.io. --[ Redis 2.8.8 ] Release date: 25 Mar 2014 # UPGRADE URGENCY: HIGH for Redis, LOW for Sentinel. There is a potentially critical bug fix causing data loss in Redis but it requires a combination of disk full and the use of the SHUTDOWN command. * [FIX] Fixed data loss when SHUTDOWN was used with a disk full condition. * [FIX] Fixed a memory leak in the SORT syntax error processing. * [FIX] When Sentinel down-after-milliseconds parameter is modified at runtime now it gets propagated to all the slaves and sentinel instances of the master. * [FIX] `install_server.sh` script finally fixed. * [FIX] Different fixes to maxclients handling. * [NEW] Sentinels are now able to send update messages in a peer-to-peer fashion even if no Redis instances are available. Now the Sentinel liveness property that the most updated configuration in a given partition is propagated to all the Sentinels is extended to partitions without reachable instances. * [NEW] Sentinel safety properties are now ensured in a crash-recovery system model since some state is persisted on disk before replying to other nodes, and reloaded at startup. * [NEW] Sentinel now uses CLIENT SETNAME so that it is easy to identify Sentinels using CLIENT LIST among other clients. * [NEW] Sentinel failure detection and reconnection code improved. * [NEW] Use all 24 bits (instead of 22) for the Redis objects LRU field. Note that the new LRU algorithm using eviction pools was not backported from unstable for safery / code maturity concerns. * [NEW] Majory speedup for the INFO command (it is now 6 times faster). * [NEW] More Sentinel unit tests. * [NEW] New command DEBUG ERROR returns the specified error. Example: DEBUG ERROR "LOADING database". This is handy to write Redis client libraries unit tests. * [NEW] redis-cli now supports multi-line editing via updated linenoise lib. Thanks to Matt Stancliff and Jan-Erik Rediger for the work done in the context of this release. --[ Redis 2.8.7 ] Release date: 5 Mar 2014 # UPGRADE URGENCY: LOW for Redis, LOW for Sentinel. However this release adds new features so users may want to upgrade in order to exploit the new functionalities. * [FIX] Sometimes the absolute config file path was obtained in a wrong way. This happened when there was a "dir" directive inside the config file and at the same time the configuration file was given as a relative path to redis-server or redis-sentinel executables. * [FIX] redis-cli: Automatically enter --slave mode when SYNC or PSYNC are called during an interactive session. * [FIX] Sentinel "IDONTKNOW" error removed as it does not made sense with the new Sentinel design. This error was actually a fix for a design error in the first implementation of Sentinel. * [FIX] Sentinel: added a missing exit() call to abort after config file checks at startup. This error was introduced with an improvement in a previous 2.8 release. * [FIX] BITCOUNT: fixed unaligned access causing issues in sparc and other archs not capable of dealing with unaligned accesses. This also makes the code faster in archs where unaligned accesses are allowed. * [FIX] Sentinel: better nodes fail over start time desynchronization to avoid split-brain during the voting process needed to get authorization to fail over. This means the system is less likely to need to retry and will fail over faster. No changes in behavior / correctness. * [FIX] Force INFO used_memory_peak to match peak memory. This generated some confusion among users even if it was not an actual bug. * [NEW] Sentinel unit tests and framework. More tests needed and units must be improved in order to have less false positives, but it is a start and features a debugging console that is useful to fix tests or to inspect bugs causing tests failures. * [NEW] New Sentinel events: +/-monitor and +set used to monitor when an instance to monitor is added or removed, or when a configuration is modified via SENTINEL SET. * [NEW] Redis-cli updated to use SCAN instead of random sampling via RANDOMKEY in order to implement --bigkeys feature. Moreover the implementation now supports pipelining and reports more information at the end of the scan. Much faster, much better. A special thank you to Michael Grunder for this improvement. * [NEW] redis-cli now supports a new --intrinsic-latency mode that is able to meter the latency of a system due to kernel / hypervisor. How to use it is explained at http://redis.io/topics/latency. * [NEW] New command BITPOS: find first bit set or clear in a bitmap. * [NEW] CONFIG REWRITE calls are now logged. --[ Redis 2.8.6 ] Release date: 13 Feb 2014 # UPGRADE URGENCY: HIGH for Redis, LOW for Sentinel. Redis users using Lua scripts with EVALSHA and attached slaves and/or AOF persistence should consider upgrading ASAP. * [FIX] Fixed an critical EVALSHA script cache bug: scripts executed may not propagate to AOF / Slaves correctly under certain conditions. See issue #1549 at Github for more information. * [FIX] Fixed multiple bugs resulting into closing the link with master or slave during replication without good reasons. This will result in useless resynchronizations, or infinite loops where the replication link can't be established. * [FIX] Don't count the time needed to populate the buffers of clients waiting in MONITOR mode when populating the Slow Log entries. * [NEW] AOF write errors (like no space on device) no longer abort Redis if the fsync policy is none or every second. The database enters a read-only mode where every write is refused with an error. Normal operations are restored as soon as Redis is able to append again data to the AOF file. * [NEW] Sentinel now accepts SHUTDOWN command. --[ Redis 2.8.5 ] Release date: 4 Feb 2014 # UPGRADE URGENCY: HIGH for Redis, LOW for Sentinel. Redis users using Lua scripts with expires, and Redis users relying on the ability of Redis to block writes on RDB saving errors should plan to upgrade ASAP. * [FIX] Fixed a replication bug caused by Lua scripts + expired keys: keys could expire in the middle of scripts causing non-deterministic behavior. * [FIX] MISCONFIG error if condition fixed, the server was no longer able to stop writes on RDB misconfiguration after this error was introduced. * [FIX] REDIS_AOF_REWRITE_MIN_SIZE is now 64mb like example redis.conf default. * [FIX] Perform fflush() before fsync() in rio.c (bug without actual effects). * [FIX] Don't log MONITOR clients as disconnecting slaves. * [FIX] SENTINEL MASTER arity check fixed. Crashed the Sentinel instance when the command was given without arguments. * [NEW] Allow CONFIG and SHUTDOWN while in stale-slave state. * [NEW] Support for configurable TCP listen(2) backlog size. * [NEW] redis-cli supports SCAN via the --scan and --pattern options. * [NEW] SENTINEL SET master quorum via runtime API implemented. --[ Redis 2.8.4 ] Release date: 13 Jan 2014 # UPGRADE URGENCY: MODERATE for Redis and Sentinel. * [FIX] Makefile compatibility with non common make variants improved. * [FIX] SDIFF crash in very unlikely to trigger state fixed. * [FIX] Config rewriting fixed: don't wipe options unknown to the rewrite process. * [FIX] Set TCP port to 0 works again to disable TCP networking. * [FIX] Fixed replication with old Redis instances as masters by not sending REPLCONF ACK to them. * [FIX] Fix keyspace notifications rewrite and CONFIG GET output. * [FIX] Fix RESTORE TTL handling in 32 bit systems (32 bit overflow). * [NEW] Sentinel now has a run time configuration API. * [NEW] Log when we lost connection with master or slave. * [NEW] When instance is turned from slave to master now inherits the old master replication offset when possible. This improves the Sentinel failover procedure. --[ Redis 2.8.3 ] Release date: 11 Dec 2013 # UPGRADE URGENCY: MODERATE for Redis, HIGH for Sentinel. * [FIX] Sentinel instance role sampling fixed, the system is now more reliable during failover and when reconfiguring instances with non matching configuration. * [FIX] Inline requests are now handled even when terminated with just LF. * [FIX] Replication timeout handling greatly improved, now the slave is able to ping the master while removing the old data from memory, and while loading the new RDB file. This avoid false timeouts sensed by masters. * [FIX] Fixed a replication bug involving 32 bit instances and big datasets hard to compress that resulted into more than 2GB of RDB file sent. * [FIX] Return error for inline requests with unbalanced quotes. * [FIX] Publish the slave replication offset even when disconnected from the master if there is still a cached master instance. --[ Redis 2.8.2 ] Release date: 2 Dec 2013 # UPGRADE URGENCY: MODERATE for both Redis and Sentinel. * [FIX] Sentinel better desynchronization to avoid split-brain elections where no Sentinel managed to get elected. * [FIX] Stop accepting writes on "MISCONF" error only if master, not slave. * [FIX] Reply to PING with an error on "MISCONF" errors. --[ Redis 2.8.1 ] Release date: 25 Nov 2013 # UPGRADE URGENCY: LOW for Redis, CRITICAL for Senitnel. You don't need to upgrade your Redis instances but it is highly recommended to upgrade and restart all the Sentinel processes. * [FIX] Fixed a bug in "new Sentinel" config propagation. * [FIX] Fixed a false positive in Redis tests. --[ Redis 2.8.0 ] Release date: 22 Nov 2013 # UPGRADE URGENCY: LOW, unless you want to upgrade to new Sentinel code. * [FIX] Fixed an error in rdbWriteRaw() that should have no practical impact. * [NEW] Log the new master when SLAVEOF command is used. * [NEW] Sentinel code synchronized with the unstable branch, the new Sentinel is a reimplementation that uses more reliable algorithms. --[ Redis 2.8 Release Candidate 6 (2.7.106) ] Release date: 6 Nov 2013 This is the 6th release candidate of Redis 2.8 (official version is 2.7.106). # UPGRADE URGENCY: LOW, only new features back ported, no fixes. * [NEW] SCAN, SSCAN, HSCAN, ZSCAN commands. --[ Redis 2.8 Release Candidate 5 (2.7.105) ] Release date: 9 Oct 2013 This is the 5th release candidate of Redis 2.8 (official version is 2.7.105). Important bugs fixed inside. # UPGRADE URGENCY: HIGH because of many non critical replication bugs fixed. * [FIX] redis-cli: don't crash with --bigkeys when the key no longer exist. * [FIX] Allow AUTH / PING when disconnected from slave and serve-stale-data is no. * [FIX] PSYNC: safer handling of PSYNC requests with offsets in the future. * [FIX] Replication: Fix master timeout detection. * [FIX] Replication: Correctly install the write handler after successful PSYNC. --[ Redis 2.8 Release Candidate 4 (2.7.104) ] Release date: 30 Aug 2013 This is the fourth release candidate of Redis 2.8 (official version is 2.7.104). Important bugs fixed inside. # UPGRADE URGENCY: HIGH because of the EVAL memory leak. * [FIX] Fixed a serious EVAL memory leak in the Lua stack. * [FIX] Fixed server startup when no IPv6 address exists in any interface. * [FIX] Send MISCONFIG error when BGSAVE fails because can't fork. * [FIX] Memory efficiency with large (> a few kbytes) values improved considerably. * [NEW] DEBUG SDSLEN for sds memory debugging. --[ Redis 2.8 Release Candidate 3 (2.7.103) ] Release date: 19 Aug 2013 This is the third release candidate of Redis 2.8 (official version is 2.7.103). Important bugs fixed inside. # UPGRADE URGENCY: HIGH * [FIX] Improved expired keys collection algorithm. Even under heavy load keys to be expired can't accumulate because of lack of CPU time. * [FIX] Replication speed regression fixed (issue #1238). * [FIX] Fixed an hard to trigger PSYNC bug. * [FIX] Fixed Issue #1240, ZUNIONSTORE could lead to wrong result. * [NEW] Add per-db average TTL information in INFO output. * [NEW] redis-benchmark improvements. * [NEW] dict.c API wrong usage detection. --[ Redis 2.8 Release Candidate 2 (2.7.102) ] Release date: 30 Jul 2013 This is the second release candidate of Redis 2.8 (official version is 2.7.102). Important bugs fixed inside. # UPGRADE URGENCY: HIGH * [FIX] Fixed a critical replication bug, see issue #1221. * [NEW] The new inline protocol now accepts quoted strings like, for example you can now type in a telnet session: set 'foo bar' "hello world\n". --[ Redis 2.8 Release Candidate 1 (2.7.101) ] Release date: 18 Jul 2013 This is the first release candidate of Redis 2.8 (official version is 2.7.101). The following is a list of improvements in Redis 2.8, compared to Redis 2.6. * [NEW] Slaves are now able to partially resynchronize with the master, so most of the times a full resynchronization with the RDB creation in the master side is not needed when the master-slave link is disconnected for a short amount of time. * [NEW] Experimental IPv6 support. * [NEW] Slaves explicitly ping masters now, a master is able to detect a timed out slave independently. * [NEW] Masters can stop accepting writes if not enough slaves with a given maximum latency are connected. * [NEW] Keyspace changes notifications via Pub/Sub. * [NEW] CONFIG SET maxclients is now available. * [NEW] Ability to bind multiple IP addresses. * [NEW] Set process names so that you can recognize, in the "ps" command output, the listening port of an instance, or if it is a saving child. * [NEW] Automatic memory check on crash. * [NEW] CONFIG REWRITE is able to materialize the changes in the configuration operated using CONFIG SET into the redis.conf file. * [NEW] More NetBSD friendly code base. * [NEW] PUBSUB command for Pub/Sub introspection capabilities. * [NEW] EVALSHA can now be replicated as such, without requiring to be expanded to a full EVAL for the replication link. * [NEW] Better Lua scripts error reporting. * [NEW] SDIFF performance improved. * [FIX] A number of bugfixes. Migrating from 2.6 to 2.8 ========================= Redis 2.6 is mostly a strict subset of 2.8. However there are a few things that you should be aware of: The following commands changed behavior: * The TTL and PTTL commands now return -2 if the key does not exist and -1 if it exists but has no associated expire. Redis 2.6 and previous versions used to return -1 for both the conditions. * SORT with ALPHA now sorts according to local collation locale if no STORE option is used. * ZADD/ZINCRBY are now able to accept a bigger range of values as valid scores, that is, all the values you may end having as a result of calling ZINCRBY multiple times. * Many errors are now prefixed by a more specific error code instead of the generic -ERR, for example -WRONGTYPE, -NOAUTH, ... * PUBLISH called inside Lua scripts is now correctly propagated to slaves. The following redis.conf and CONFIG GET / SET parameters changed: * logfile now uses the empty string in order to log to standard output, so 'logfile stdout' is now invalid, use 'logfile ""' instead. The following INFO fields changed format in a non-backward compatible way: * The list of slaves in INFO is now in field=value format. Replication: Redis 2.8 can be used as slave for Redis 2.6, but doing this is only a good idea for the short amount of time needed to upgrade your servers. We suggest to update both master and slaves at about the same time. -------------------------------------------------------------------------------- Credits: Where not specified the implementation and design is done by Salvatore Sanfilippo.

Redis is a DSL (Domain Specific Language) that manipulates abstract data types and implemented as a TCP daemon. Commands manipulate a key space where keys are binary-safe strings and values are different kinds of abstract data types. Every data type represents an abstract version of a fundamental data structure. For instance Redis Lists are an abstract representation of linked lists. In Redis, the essence of a data type isn't just the kind of operations that the data types support, but also the space and time complexity of the data type and the operations performed upon it. 2 - Memory storage is #1. The Redis data set, composed of defined key-value pairs, is primarily stored in the computer's memory. The amount of memory in all kinds of computers, including entry-level servers, is increasing significantly each year. Memory is fast, and allows Redis to have very predictable performance. Datasets composed of 10k or 40 millions keys will perform similarly. Complex data types like Redis Sorted Sets are easy to implement and manipulate in memory with good performance, making Redis very simple. Redis will continue to explore alternative options (where data can be optionally stored on disk, say) but the main goal of the project remains the development of an in-memory database. 3 - Fundamental data structures for a fundamental API. The Redis API is a direct consequence of fundamental data structures. APIs can often be arbitrary but not an API that resembles the nature of fundamental data structures. If we ever meet intelligent life forms from another part of the universe, they'll likely know, understand and recognize the same basic data structures we have in our computer science books. Redis will avoid intermediate layers in API, so that the complexity is obvious and more complex operations can be performed as the sum of the basic operations. 4 - Code is like a poem; it's not just something we write to reach some practical result. Sometimes people that are far from the Redis philosophy suggest using other code written by other authors (frequently in other languages) in order to implement something Redis currently lacks. But to us this is like if Shakespeare decided to end Enrico IV using the Paradiso from the Divina Commedia. Is using any external code a bad idea? Not at all. Like in "One Thousand and One Nights" smaller self contained stories are embedded in a bigger story, we'll be happy to use beautiful self contained libraries when needed. At the same time, when writing the Redis story we're trying to write smaller stories that will fit in to other code. 5 - We're against complexity. We believe designing systems is a fight against complexity. We'll accept to fight the complexity when it's worthwhile but we'll try hard to recognize when a small feature is not worth 1000s of lines of code. Most of the time the best way to fight complexity is by not creating it at all. 6 - Two levels of API. The Redis API has two levels: 1) a subset of the API fits naturally into a distributed version of Redis and 2) a more complex API that supports multi-key operations. Both are useful if used judiciously but there's no way to make the more complex multi-keys API distributed in an opaque way without violating our other principles. We don't want to provide the illusion of something that will work magically when actually it can't in all cases. Instead we'll provide commands to quickly migrate keys from one instance to another to perform multi-key operations and expose the tradeoffs to the user. 7 - We optimize for joy. We believe writing code is a lot of hard work, and the only way it can be worth is by enjoying it. When there is no longer joy in writing code, the best thing to do is stop. To prevent this, we'll avoid taking paths that will make Redis less of a joy to develop. ================================================ FILE: extern/deprecated/redis-2.8.21/Makefile ================================================ # Top level makefile, the real shit is at src/Makefile default: all .DEFAULT: cd src && $(MAKE) $@ install: cd src && $(MAKE) $@ .PHONY: install ================================================ FILE: extern/deprecated/redis-2.8.21/README ================================================ Where to find complete Redis documentation? ------------------------------------------- This README is just a fast "quick start" document. You can find more detailed documentation at http://redis.io Building Redis -------------- Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD. We support big endian and little endian architectures. It may compile on Solaris derived systems (for instance SmartOS) but our support for this platform is "best effort" and Redis is not guaranteed to work as well as in Linux, OSX, and *BSD there. It is as simple as: % make You can run a 32 bit Redis binary using: % make 32bit After building Redis is a good idea to test it, using: % make test Fixing build problems with dependencies or cached build options —-------- Redis has some dependencies which are included into the "deps" directory. "make" does not rebuild dependencies automatically, even if something in the source code of dependencies is changes. When you update the source code with `git pull` or when code inside the dependencies tree is modified in any other way, make sure to use the following command in order to really clean everything and rebuild from scratch: make distclean This will clean: jemalloc, lua, hiredis, linenoise. Also if you force certain build options like 32bit target, no C compiler optimizations (for debugging purposes), and other similar build time options, those options are cached indefinitely until you issue a "make distclean" command. Fixing problems building 32 bit binaries --------- If after building Redis with a 32 bit target you need to rebuild it with a 64 bit target, or the other way around, you need to perform a "make distclean" in the root directory of the Redis distribution. In case of build errors when trying to build a 32 bit binary of Redis, try the following steps: * Install the packages libc6-dev-i386 (also try g++-multilib). * Try using the following command line instead of "make 32bit": make CFLAGS="-m32 -march=native" LDFLAGS="-m32" Allocator --------- Selecting a non-default memory allocator when building Redis is done by setting the `MALLOC` environment variable. Redis is compiled and linked against libc malloc by default, with the exception of jemalloc being the default on Linux systems. This default was picked because jemalloc has proven to have fewer fragmentation problems than libc malloc. To force compiling against libc malloc, use: % make MALLOC=libc To compile against jemalloc on Mac OS X systems, use: % make MALLOC=jemalloc Verbose build ------------- Redis will build with a user friendly colorized output by default. If you want to see a more verbose output use the following: % make V=1 Running Redis ------------- To run Redis with the default configuration just type: % cd src % ./redis-server If you want to provide your redis.conf, you have to run it using an additional parameter (the path of the configuration file): % cd src % ./redis-server /path/to/redis.conf It is possible to alter the Redis configuration passing parameters directly as options using the command line. Examples: % ./redis-server --port 9999 --slaveof 127.0.0.1 6379 % ./redis-server /etc/redis/6379.conf --loglevel debug All the options in redis.conf are also supported as options using the command line, with exactly the same name. Playing with Redis ------------------ You can use redis-cli to play with Redis. Start a redis-server instance, then in another terminal try the following: % cd src % ./redis-cli redis> ping PONG redis> set foo bar OK redis> get foo "bar" redis> incr mycounter (integer) 1 redis> incr mycounter (integer) 2 redis> You can find the list of all the available commands here: http://redis.io/commands Installing Redis ----------------- In order to install Redis binaries into /usr/local/bin just use: % make install You can use "make PREFIX=/some/other/directory install" if you wish to use a different destination. Make install will just install binaries in your system, but will not configure init scripts and configuration files in the appropriate place. This is not needed if you want just to play a bit with Redis, but if you are installing it the proper way for a production system, we have a script doing this for Ubuntu and Debian systems: % cd utils % ./install_server.sh The script will ask you a few questions and will setup everything you need to run Redis properly as a background daemon that will start again on system reboots. You'll be able to stop and start Redis using the script named /etc/init.d/redis_, for instance /etc/init.d/redis_6379.

It is minimalistic because it just adds minimal support for the protocol, but at the same time it uses an high level printf-alike API in order to make it much higher level than otherwise suggested by its minimal code base and the lack of explicit bindings for every Redis command. Apart from supporting sending commands and receiving replies, it comes with a reply parser that is decoupled from the I/O layer. It is a stream parser designed for easy reusability, which can for instance be used in higher level language bindings for efficient reply parsing. Hiredis only supports the binary-safe Redis protocol, so you can use it with any Redis version >= 1.2.0. The library comes with multiple APIs. There is the *synchronous API*, the *asynchronous API* and the *reply parsing API*. ## UPGRADING Version 0.9.0 is a major overhaul of hiredis in every aspect. However, upgrading existing code using hiredis should not be a big pain. The key thing to keep in mind when upgrading is that hiredis >= 0.9.0 uses a `redisContext*` to keep state, in contrast to the stateless 0.0.1 that only has a file descriptor to work with. ## Synchronous API To consume the synchronous API, there are only a few function calls that need to be introduced: redisContext *redisConnect(const char *ip, int port); void *redisCommand(redisContext *c, const char *format, ...); void freeReplyObject(void *reply); ### Connecting The function `redisConnect` is used to create a so-called `redisContext`. The context is where Hiredis holds state for a connection. The `redisContext` struct has an integer `err` field that is non-zero when an the connection is in an error state. The field `errstr` will contain a string with a description of the error. More information on errors can be found in the **Errors** section. After trying to connect to Redis using `redisConnect` you should check the `err` field to see if establishing the connection was successful: redisContext *c = redisConnect("127.0.0.1", 6379); if (c != NULL && c->err) { printf("Error: %s\n", c->errstr); // handle error } ### Sending commands There are several ways to issue commands to Redis. The first that will be introduced is `redisCommand`. This function takes a format similar to printf. In the simplest form, it is used like this: reply = redisCommand(context, "SET foo bar"); The specifier `%s` interpolates a string in the command, and uses `strlen` to determine the length of the string: reply = redisCommand(context, "SET foo %s", value); When you need to pass binary safe strings in a command, the `%b` specifier can be used. Together with a pointer to the string, it requires a `size_t` length argument of the string: reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen); Internally, Hiredis splits the command in different arguments and will convert it to the protocol used to communicate with Redis. One or more spaces separates arguments, so you can use the specifiers anywhere in an argument: reply = redisCommand(context, "SET key:%s %s", myid, value); ### Using replies The return value of `redisCommand` holds a reply when the command was successfully executed. When an error occurs, the return value is `NULL` and the `err` field in the context will be set (see section on **Errors**). Once an error is returned the context cannot be reused and you should set up a new connection. The standard replies that `redisCommand` are of the type `redisReply`. The `type` field in the `redisReply` should be used to test what kind of reply was received: * **`REDIS_REPLY_STATUS`**: * The command replied with a status reply. The status string can be accessed using `reply->str`. The length of this string can be accessed using `reply->len`. * **`REDIS_REPLY_ERROR`**: * The command replied with an error. The error string can be accessed identical to `REDIS_REPLY_STATUS`. * **`REDIS_REPLY_INTEGER`**: * The command replied with an integer. The integer value can be accessed using the `reply->integer` field of type `long long`. * **`REDIS_REPLY_NIL`**: * The command replied with a **nil** object. There is no data to access. * **`REDIS_REPLY_STRING`**: * A bulk (string) reply. The value of the reply can be accessed using `reply->str`. The length of this string can be accessed using `reply->len`. * **`REDIS_REPLY_ARRAY`**: * A multi bulk reply. The number of elements in the multi bulk reply is stored in `reply->elements`. Every element in the multi bulk reply is a `redisReply` object as well and can be accessed via `reply->element[..index..]`. Redis may reply with nested arrays but this is fully supported. Replies should be freed using the `freeReplyObject()` function. Note that this function will take care of freeing sub-replies objects contained in arrays and nested arrays, so there is no need for the user to free the sub replies (it is actually harmful and will corrupt the memory). **Important:** the current version of hiredis (0.10.0) free's replies when the asynchronous API is used. This means you should not call `freeReplyObject` when you use this API. The reply is cleaned up by hiredis _after_ the callback returns. This behavior will probably change in future releases, so make sure to keep an eye on the changelog when upgrading (see issue #39). ### Cleaning up To disconnect and free the context the following function can be used: void redisFree(redisContext *c); This function immediately closes the socket and then free's the allocations done in creating the context. ### Sending commands (cont'd) Together with `redisCommand`, the function `redisCommandArgv` can be used to issue commands. It has the following prototype: void *redisCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen); It takes the number of arguments `argc`, an array of strings `argv` and the lengths of the arguments `argvlen`. For convenience, `argvlen` may be set to `NULL` and the function will use `strlen(3)` on every argument to determine its length. Obviously, when any of the arguments need to be binary safe, the entire array of lengths `argvlen` should be provided. The return value has the same semantic as `redisCommand`. ### Pipelining To explain how Hiredis supports pipelining in a blocking connection, there needs to be understanding of the internal execution flow. When any of the functions in the `redisCommand` family is called, Hiredis first formats the command according to the Redis protocol. The formatted command is then put in the output buffer of the context. This output buffer is dynamic, so it can hold any number of commands. After the command is put in the output buffer, `redisGetReply` is called. This function has the following two execution paths: 1. The input buffer is non-empty: * Try to parse a single reply from the input buffer and return it * If no reply could be parsed, continue at *2* 2. The input buffer is empty: * Write the **entire** output buffer to the socket * Read from the socket until a single reply could be parsed The function `redisGetReply` is exported as part of the Hiredis API and can be used when a reply is expected on the socket. To pipeline commands, the only things that needs to be done is filling up the output buffer. For this cause, two commands can be used that are identical to the `redisCommand` family, apart from not returning a reply: void redisAppendCommand(redisContext *c, const char *format, ...); void redisAppendCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen); After calling either function one or more times, `redisGetReply` can be used to receive the subsequent replies. The return value for this function is either `REDIS_OK` or `REDIS_ERR`, where the latter means an error occurred while reading a reply. Just as with the other commands, the `err` field in the context can be used to find out what the cause of this error is. The following examples shows a simple pipeline (resulting in only a single call to `write(2)` and a single call to `read(2)`): redisReply *reply; redisAppendCommand(context,"SET foo bar"); redisAppendCommand(context,"GET foo"); redisGetReply(context,&reply); // reply for SET freeReplyObject(reply); redisGetReply(context,&reply); // reply for GET freeReplyObject(reply); This API can also be used to implement a blocking subscriber: reply = redisCommand(context,"SUBSCRIBE foo"); freeReplyObject(reply); while(redisGetReply(context,&reply) == REDIS_OK) { // consume message freeReplyObject(reply); } ### Errors When a function call is not successful, depending on the function either `NULL` or `REDIS_ERR` is returned. The `err` field inside the context will be non-zero and set to one of the following constants: * **`REDIS_ERR_IO`**: There was an I/O error while creating the connection, trying to write to the socket or read from the socket. If you included `errno.h` in your application, you can use the global `errno` variable to find out what is wrong. * **`REDIS_ERR_EOF`**: The server closed the connection which resulted in an empty read. * **`REDIS_ERR_PROTOCOL`**: There was an error while parsing the protocol. * **`REDIS_ERR_OTHER`**: Any other error. Currently, it is only used when a specified hostname to connect to cannot be resolved. In every case, the `errstr` field in the context will be set to hold a string representation of the error. ## Asynchronous API Hiredis comes with an asynchronous API that works easily with any event library. Examples are bundled that show using Hiredis with [libev](http://software.schmorp.de/pkg/libev.html) and [libevent](http://monkey.org/~provos/libevent/). ### Connecting The function `redisAsyncConnect` can be used to establish a non-blocking connection to Redis. It returns a pointer to the newly created `redisAsyncContext` struct. The `err` field should be checked after creation to see if there were errors creating the connection. Because the connection that will be created is non-blocking, the kernel is not able to instantly return if the specified host and port is able to accept a connection. redisAsyncContext *c = redisAsyncConnect("127.0.0.1", 6379); if (c->err) { printf("Error: %s\n", c->errstr); // handle error } The asynchronous context can hold a disconnect callback function that is called when the connection is disconnected (either because of an error or per user request). This function should have the following prototype: void(const redisAsyncContext *c, int status); On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err` field in the context can be accessed to find out the cause of the error. The context object is always free'd after the disconnect callback fired. When a reconnect is needed, the disconnect callback is a good point to do so. Setting the disconnect callback can only be done once per context. For subsequent calls it will return `REDIS_ERR`. The function to set the disconnect callback has the following prototype: int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn); ### Sending commands and their callbacks In an asynchronous context, commands are automatically pipelined due to the nature of an event loop. Therefore, unlike the synchronous API, there is only a single way to send commands. Because commands are sent to Redis asynchronously, issuing a command requires a callback function that is called when the reply is received. Reply callbacks should have the following prototype: void(redisAsyncContext *c, void *reply, void *privdata); The `privdata` argument can be used to curry arbitrary data to the callback from the point where the command is initially queued for execution. The functions that can be used to issue commands in an asynchronous context are: int redisAsyncCommand( redisAsyncContext *ac, redisCallbackFn *fn, void *privdata, const char *format, ...); int redisAsyncCommandArgv( redisAsyncContext *ac, redisCallbackFn *fn, void *privdata, int argc, const char **argv, const size_t *argvlen); Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is returned on calls to the `redisAsyncCommand` family. If the reply for a command with a `NULL` callback is read, it is immediately free'd. When the callback for a command is non-`NULL`, the memory is free'd immediately following the callback: the reply is only valid for the duration of the callback. All pending callbacks are called with a `NULL` reply when the context encountered an error. ### Disconnecting An asynchronous connection can be terminated using: void redisAsyncDisconnect(redisAsyncContext *ac); When this function is called, the connection is **not** immediately terminated. Instead, new commands are no longer accepted and the connection is only terminated when all pending commands have been written to the socket, their respective replies have been read and their respective callbacks have been executed. After this, the disconnection callback is executed with the `REDIS_OK` status and the context object is free'd. ### Hooking it up to event library *X* There are a few hooks that need to be set on the context object after it is created. See the `adapters/` directory for bindings to *libev* and *libevent*. ## Reply parsing API Hiredis comes with a reply parsing API that makes it easy for writing higher level language bindings. The reply parsing API consists of the following functions: redisReader *redisReaderCreate(void); void redisReaderFree(redisReader *reader); int redisReaderFeed(redisReader *reader, const char *buf, size_t len); int redisReaderGetReply(redisReader *reader, void **reply); The same set of functions are used internally by hiredis when creating a normal Redis context, the above API just exposes it to the user for a direct usage. ### Usage The function `redisReaderCreate` creates a `redisReader` structure that holds a buffer with unparsed data and state for the protocol parser. Incoming data -- most likely from a socket -- can be placed in the internal buffer of the `redisReader` using `redisReaderFeed`. This function will make a copy of the buffer pointed to by `buf` for `len` bytes. This data is parsed when `redisReaderGetReply` is called. This function returns an integer status and a reply object (as described above) via `void **reply`. The returned status can be either `REDIS_OK` or `REDIS_ERR`, where the latter means something went wrong (either a protocol error, or an out of memory error). The parser limits the level of nesting for multi bulk payloads to 7. If the multi bulk nesting level is higher than this, the parser returns an error. ### Customizing replies The function `redisReaderGetReply` creates `redisReply` and makes the function argument `reply` point to the created `redisReply` variable. For instance, if the response of type `REDIS_REPLY_STATUS` then the `str` field of `redisReply` will hold the status as a vanilla C string. However, the functions that are responsible for creating instances of the `redisReply` can be customized by setting the `fn` field on the `redisReader` struct. This should be done immediately after creating the `redisReader`. For example, [hiredis-rb](https://github.com/pietern/hiredis-rb/blob/master/ext/hiredis_ext/reader.c) uses customized reply object functions to create Ruby objects. ### Reader max buffer Both when using the Reader API directly or when using it indirectly via a normal Redis context, the redisReader structure uses a buffer in order to accumulate data from the server. Usually this buffer is destroyed when it is empty and is larger than 16 kb in order to avoid wasting memory in unused buffers However when working with very big payloads destroying the buffer may slow down performances considerably, so it is possible to modify the max size of an idle buffer changing the value of the `maxbuf` field of the reader structure to the desired value. The special value of 0 means that there is no maximum value for an idle buffer, so the buffer will never get freed. For instance if you have a normal Redis context you can set the maximum idle buffer to zero (unlimited) just with: context->reader->maxbuf = 0; This should be done only in order to maximize performances when working with large payloads.

Important bug fixes are all mentioned, but internal enhancements are omitted here for brevity (even though they are more fun to write about). Much more detail can be found in the git revision history: https://github.com/jemalloc/jemalloc * 3.6.0 (March 31, 2014) This version contains a critical bug fix for a regression present in 3.5.0 and 3.5.1. Bug fixes: - Fix a regression in arena_chunk_alloc() that caused crashes during small/large allocation if chunk allocation failed. In the absence of this bug, chunk allocation failure would result in allocation failure, e.g. NULL return from malloc(). This regression was introduced in 3.5.0. - Fix backtracing for gcc intrinsics-based backtracing by specifying -fno-omit-frame-pointer to gcc. Note that the application (and all the libraries it links to) must also be compiled with this option for backtracing to be reliable. - Use dss allocation precedence for huge allocations as well as small/large allocations. - Fix test assertion failure message formatting. This bug did not manifect on x86_64 systems because of implementation subtleties in va_list. - Fix inconsequential test failures for hash and SFMT code. New features: - Support heap profiling on FreeBSD. This feature depends on the proc filesystem being mounted during heap profile dumping. * 3.5.1 (February 25, 2014) This version primarily addresses minor bugs in test code. Bug fixes: - Configure Solaris/Illumos to use MADV_FREE. - Fix junk filling for mremap(2)-based huge reallocation. This is only relevant if configuring with the --enable-mremap option specified. - Avoid compilation failure if 'restrict' C99 keyword is not supported by the compiler. - Add a configure test for SSE2 rather than assuming it is usable on i686 systems. This fixes test compilation errors, especially on 32-bit Linux systems. - Fix mallctl argument size mismatches (size_t vs. uint64_t) in the stats unit test. - Fix/remove flawed alignment-related overflow tests. - Prevent compiler optimizations that could change backtraces in the prof_accum unit test. * 3.5.0 (January 22, 2014) This version focuses on refactoring and automated testing, though it also includes some non-trivial heap profiling optimizations not mentioned below. New features: - Add the *allocx() API, which is a successor to the experimental *allocm() API. The *allocx() functions are slightly simpler to use because they have fewer parameters, they directly return the results of primary interest, and mallocx()/rallocx() avoid the strict aliasing pitfall that allocm()/rallocm() share with posix_memalign(). Note that *allocm() is slated for removal in the next non-bugfix release. - Add support for LinuxThreads. Bug fixes: - Unless heap profiling is enabled, disable floating point code and don't link with libm. This, in combination with e.g. EXTRA_CFLAGS=-mno-sse on x64 systems, makes it possible to completely disable floating point register use. Some versions of glibc neglect to save/restore caller-saved floating point registers during dynamic lazy symbol loading, and the symbol loading code uses whatever malloc the application happens to have linked/loaded with, the result being potential floating point register corruption. - Report ENOMEM rather than EINVAL if an OOM occurs during heap profiling backtrace creation in imemalign(). This bug impacted posix_memalign() and aligned_alloc(). - Fix a file descriptor leak in a prof_dump_maps() error path. - Fix prof_dump() to close the dump file descriptor for all relevant error paths. - Fix rallocm() to use the arena specified by the ALLOCM_ARENA(s) flag for allocation, not just deallocation. - Fix a data race for large allocation stats counters. - Fix a potential infinite loop during thread exit. This bug occurred on Solaris, and could affect other platforms with similar pthreads TSD implementations. - Don't junk-fill reallocations unless usable size changes. This fixes a violation of the *allocx()/*allocm() semantics. - Fix growing large reallocation to junk fill new space. - Fix huge deallocation to junk fill when munmap is disabled. - Change the default private namespace prefix from empty to je_, and change --with-private-namespace-prefix so that it prepends an additional prefix rather than replacing je_. This reduces the likelihood of applications which statically link jemalloc experiencing symbol name collisions. - Add missing private namespace mangling (relevant when --with-private-namespace is specified). - Add and use JEMALLOC_INLINE_C so that static inline functions are marked as static even for debug builds. - Add a missing mutex unlock in a malloc_init_hard() error path. In practice this error path is never executed. - Fix numerous bugs in malloc_strotumax() error handling/reporting. These bugs had no impact except for malformed inputs. - Fix numerous bugs in malloc_snprintf(). These bugs were not exercised by existing calls, so they had no impact. * 3.4.1 (October 20, 2013) Bug fixes: - Fix a race in the "arenas.extend" mallctl that could cause memory corruption of internal data structures and subsequent crashes. - Fix Valgrind integration flaws that caused Valgrind warnings about reads of uninitialized memory in: + arena chunk headers + internal zero-initialized data structures (relevant to tcache and prof code) - Preserve errno during the first allocation. A readlink(2) call during initialization fails unless /etc/malloc.conf exists, so errno was typically set during the first allocation prior to this fix. - Fix compilation warnings reported by gcc 4.8.1. * 3.4.0 (June 2, 2013) This version is essentially a small bugfix release, but the addition of aarch64 support requires that the minor version be incremented. Bug fixes: - Fix race-triggered deadlocks in chunk_record(). These deadlocks were typically triggered by multiple threads concurrently deallocating huge objects. New features: - Add support for the aarch64 architecture. * 3.3.1 (March 6, 2013) This version fixes bugs that are typically encountered only when utilizing custom run-time options. Bug fixes: - Fix a locking order bug that could cause deadlock during fork if heap profiling were enabled. - Fix a chunk recycling bug that could cause the allocator to lose track of whether a chunk was zeroed. On FreeBSD, NetBSD, and OS X, it could cause corruption if allocating via sbrk(2) (unlikely unless running with the "dss:primary" option specified). This was completely harmless on Linux unless using mlockall(2) (and unlikely even then, unless the --disable-munmap configure option or the "dss:primary" option was specified). This regression was introduced in 3.1.0 by the mlockall(2)/madvise(2) interaction fix. - Fix TLS-related memory corruption that could occur during thread exit if the thread never allocated memory. Only the quarantine and prof facilities were susceptible. - Fix two quarantine bugs: + Internal reallocation of the quarantined object array leaked the old array. + Reallocation failure for internal reallocation of the quarantined object array (very unlikely) resulted in memory corruption. - Fix Valgrind integration to annotate all internally allocated memory in a way that keeps Valgrind happy about internal data structure access. - Fix building for s390 systems. * 3.3.0 (January 23, 2013) This version includes a few minor performance improvements in addition to the listed new features and bug fixes. New features: - Add clipping support to lg_chunk option processing. - Add the --enable-ivsalloc option. - Add the --without-export option. - Add the --disable-zone-allocator option. Bug fixes: - Fix "arenas.extend" mallctl to output the number of arenas. - Fix chunk_recycle() to unconditionally inform Valgrind that returned memory is undefined. - Fix build break on FreeBSD related to alloca.h. * 3.2.0 (November 9, 2012) In addition to a couple of bug fixes, this version modifies page run allocation and dirty page purging algorithms in order to better control page-level virtual memory fragmentation. Incompatible changes: - Change the "opt.lg_dirty_mult" default from 5 to 3 (32:1 to 8:1). Bug fixes: - Fix dss/mmap allocation precedence code to use recyclable mmap memory only after primary dss allocation fails. - Fix deadlock in the "arenas.purge" mallctl. This regression was introduced in 3.1.0 by the addition of the "arena..purge" mallctl. * 3.1.0 (October 16, 2012) New features: - Auto-detect whether running inside Valgrind, thus removing the need to manually specify MALLOC_CONF=valgrind:true. - Add the "arenas.extend" mallctl, which allows applications to create manually managed arenas. - Add the ALLOCM_ARENA() flag for {,r,d}allocm(). - Add the "opt.dss", "arena..dss", and "stats.arenas..dss" mallctls, which provide control over dss/mmap precedence. - Add the "arena..purge" mallctl, which obsoletes "arenas.purge". - Define LG_QUANTUM for hppa. Incompatible changes: - Disable tcache by default if running inside Valgrind, in order to avoid making unallocated objects appear reachable to Valgrind. - Drop const from malloc_usable_size() argument on Linux. Bug fixes: - Fix heap profiling crash if sampled object is freed via realloc(p, 0). - Remove const from __*_hook variable declarations, so that glibc can modify them during process forking. - Fix mlockall(2)/madvise(2) interaction. - Fix fork(2)-related deadlocks. - Fix error return value for "thread.tcache.enabled" mallctl. * 3.0.0 (May 11, 2012) Although this version adds some major new features, the primary focus is on internal code cleanup that facilitates maintainability and portability, most of which is not reflected in the ChangeLog. This is the first release to incorporate substantial contributions from numerous other developers, and the result is a more broadly useful allocator (see the git revision history for contribution details). Note that the license has been unified, thanks to Facebook granting a license under the same terms as the other copyright holders (see COPYING). New features: - Implement Valgrind support, redzones, and quarantine. - Add support for additional platforms: + FreeBSD + Mac OS X Lion + MinGW + Windows (no support yet for replacing the system malloc) - Add support for additional architectures: + MIPS + SH4 + Tilera - Add support for cross compiling. - Add nallocm(), which rounds a request size up to the nearest size class without actually allocating. - Implement aligned_alloc() (blame C11). - Add the "thread.tcache.enabled" mallctl. - Add the "opt.prof_final" mallctl. - Update pprof (from gperftools 2.0). - Add the --with-mangling option. - Add the --disable-experimental option. - Add the --disable-munmap option, and make it the default on Linux. - Add the --enable-mremap option, which disables use of mremap(2) by default. Incompatible changes: - Enable stats by default. - Enable fill by default. - Disable lazy locking by default. - Rename the "tcache.flush" mallctl to "thread.tcache.flush". - Rename the "arenas.pagesize" mallctl to "arenas.page". - Change the "opt.lg_prof_sample" default from 0 to 19 (1 B to 512 KiB). - Change the "opt.prof_accum" default from true to false. Removed features: - Remove the swap feature, including the "config.swap", "swap.avail", "swap.prezeroed", "swap.nfds", and "swap.fds" mallctls. - Remove highruns statistics, including the "stats.arenas..bins..highruns" and "stats.arenas..lruns..highruns" mallctls. - As part of small size class refactoring, remove the "opt.lg_[qc]space_max", "arenas.cacheline", "arenas.subpage", "arenas.[tqcs]space_{min,max}", and "arenas.[tqcs]bins" mallctls. - Remove the "arenas.chunksize" mallctl. - Remove the "opt.lg_prof_tcmax" option. - Remove the "opt.lg_prof_bt_max" option. - Remove the "opt.lg_tcache_gc_sweep" option. - Remove the --disable-tiny option, including the "config.tiny" mallctl. - Remove the --enable-dynamic-page-shift configure option. - Remove the --enable-sysv configure option. Bug fixes: - Fix a statistics-related bug in the "thread.arena" mallctl that could cause invalid statistics and crashes. - Work around TLS deallocation via free() on Linux. This bug could cause write-after-free memory corruption. - Fix a potential deadlock that could occur during interval- and growth-triggered heap profile dumps. - Fix large calloc() zeroing bugs due to dropping chunk map unzeroed flags. - Fix chunk_alloc_dss() to stop claiming memory is zeroed. This bug could cause memory corruption and crashes with --enable-dss specified. - Fix fork-related bugs that could cause deadlock in children between fork and exec. - Fix malloc_stats_print() to honor 'b' and 'l' in the opts parameter. - Fix realloc(p, 0) to act like free(p). - Do not enforce minimum alignment in memalign(). - Check for NULL pointer in malloc_usable_size(). - Fix an off-by-one heap profile statistics bug that could be observed in interval- and growth-triggered heap profiles. - Fix the "epoch" mallctl to update cached stats even if the passed in epoch is 0. - Fix bin->runcur management to fix a layout policy bug.

This is a serious bug that could cause memory corruption and/or crashes. - Fix huge_ralloc() to maintain chunk statistics. - Fix malloc_stats_print(..., "a") output. * 2.2.4 (November 5, 2011) Bug fixes: - Initialize arenas_tsd before using it. This bug existed for 2.2.[0-3], as well as for --disable-tls builds in earlier releases. - Do not assume a 4 KiB page size in test/rallocm.c. * 2.2.3 (August 31, 2011) This version fixes numerous bugs related to heap profiling. Bug fixes: - Fix a prof-related race condition. This bug could cause memory corruption, but only occurred in non-default configurations (prof_accum:false). - Fix off-by-one backtracing issues (make sure that prof_alloc_prep() is excluded from backtraces). - Fix a prof-related bug in realloc() (only triggered by OOM errors). - Fix prof-related bugs in allocm() and rallocm(). - Fix prof_tdata_cleanup() for --disable-tls builds. - Fix a relative include path, to fix objdir builds. * 2.2.2 (July 30, 2011) Bug fixes: - Fix a build error for --disable-tcache. - Fix assertions in arena_purge() (for real this time). - Add the --with-private-namespace option. This is a workaround for symbol conflicts that can inadvertently arise when using static libraries. * 2.2.1 (March 30, 2011) Bug fixes: - Implement atomic operations for x86/x64. This fixes compilation failures for versions of gcc that are still in wide use. - Fix an assertion in arena_purge(). * 2.2.0 (March 22, 2011) This version incorporates several improvements to algorithms and data structures that tend to reduce fragmentation and increase speed. New features: - Add the "stats.cactive" mallctl. - Update pprof (from google-perftools 1.7). - Improve backtracing-related configuration logic, and add the --disable-prof-libgcc option. Bug fixes: - Change default symbol visibility from "internal", to "hidden", which decreases the overhead of library-internal function calls. - Fix symbol visibility so that it is also set on OS X. - Fix a build dependency regression caused by the introduction of the .pic.o suffix for PIC object files. - Add missing checks for mutex initialization failures. - Don't use libgcc-based backtracing except on x64, where it is known to work. - Fix deadlocks on OS X that were due to memory allocation in pthread_mutex_lock(). - Heap profiling-specific fixes: + Fix memory corruption due to integer overflow in small region index computation, when using a small enough sample interval that profiling context pointers are stored in small run headers. + Fix a bootstrap ordering bug that only occurred with TLS disabled. + Fix a rallocm() rsize bug. + Fix error detection bugs for aligned memory allocation. * 2.1.3 (March 14, 2011) Bug fixes: - Fix a cpp logic regression (due to the "thread.{de,}allocatedp" mallctl fix for OS X in 2.1.2). - Fix a "thread.arena" mallctl bug. - Fix a thread cache stats merging bug. * 2.1.2 (March 2, 2011) Bug fixes: - Fix "thread.{de,}allocatedp" mallctl for OS X. - Add missing jemalloc.a to build system. * 2.1.1 (January 31, 2011) Bug fixes: - Fix aligned huge reallocation (affected allocm()). - Fix the ALLOCM_LG_ALIGN macro definition. - Fix a heap dumping deadlock. - Fix a "thread.arena" mallctl bug. * 2.1.0 (December 3, 2010) This version incorporates some optimizations that can't quite be considered bug fixes. New features: - Use Linux's mremap(2) for huge object reallocation when possible. - Avoid locking in mallctl*() when possible. - Add the "thread.[de]allocatedp" mallctl's. - Convert the manual page source from roff to DocBook, and generate both roff and HTML manuals. Bug fixes: - Fix a crash due to incorrect bootstrap ordering. This only impacted --enable-debug --enable-dss configurations. - Fix a minor statistics bug for mallctl("swap.avail", ...). * 2.0.1 (October 29, 2010) Bug fixes: - Fix a race condition in heap profiling that could cause undefined behavior if "opt.prof_accum" were disabled. - Add missing mutex unlocks for some OOM error paths in the heap profiling code. - Fix a compilation error for non-C99 builds. * 2.0.0 (October 24, 2010) This version focuses on the experimental *allocm() API, and on improved run-time configuration/introspection. Nonetheless, numerous performance improvements are also included. New features: - Implement the experimental {,r,s,d}allocm() API, which provides a superset of the functionality available via malloc(), calloc(), posix_memalign(), realloc(), malloc_usable_size(), and free(). These functions can be used to allocate/reallocate aligned zeroed memory, ask for optional extra memory during reallocation, prevent object movement during reallocation, etc. - Replace JEMALLOC_OPTIONS/JEMALLOC_PROF_PREFIX with MALLOC_CONF, which is more human-readable, and more flexible. For example: JEMALLOC_OPTIONS=AJP is now: MALLOC_CONF=abort:true,fill:true,stats_print:true - Port to Apple OS X. Sponsored by Mozilla. - Make it possible for the application to control thread-->arena mappings via the "thread.arena" mallctl. - Add compile-time support for all TLS-related functionality via pthreads TSD. This is mainly of interest for OS X, which does not support TLS, but has a TSD implementation with similar performance. - Override memalign() and valloc() if they are provided by the system. - Add the "arenas.purge" mallctl, which can be used to synchronously purge all dirty unused pages. - Make cumulative heap profiling data optional, so that it is possible to limit the amount of memory consumed by heap profiling data structures. - Add per thread allocation counters that can be accessed via the "thread.allocated" and "thread.deallocated" mallctls. Incompatible changes: - Remove JEMALLOC_OPTIONS and malloc_options (see MALLOC_CONF above). - Increase default backtrace depth from 4 to 128 for heap profiling. - Disable interval-based profile dumps by default. Bug fixes: - Remove bad assertions in fork handler functions. These assertions could cause aborts for some combinations of configure settings. - Fix strerror_r() usage to deal with non-standard semantics in GNU libc. - Fix leak context reporting. This bug tended to cause the number of contexts to be underreported (though the reported number of objects and bytes were correct). - Fix a realloc() bug for large in-place growing reallocation. This bug could cause memory corruption, but it was hard to trigger. - Fix an allocation bug for small allocations that could be triggered if multiple threads raced to create a new run of backing pages. - Enhance the heap profiler to trigger samples based on usable size, rather than request size. - Fix a heap profiling bug due to sometimes losing track of requested object size for sampled objects. * 1.0.3 (August 12, 2010) Bug fixes: - Fix the libunwind-based implementation of stack backtracing (used for heap profiling). This bug could cause zero-length backtraces to be reported. - Add a missing mutex unlock in library initialization code. If multiple threads raced to initialize malloc, some of them could end up permanently blocked. * 1.0.2 (May 11, 2010) Bug fixes: - Fix junk filling of large objects, which could cause memory corruption. - Add MAP_NORESERVE support for chunk mapping, because otherwise virtual memory limits could cause swap file configuration to fail. Contributed by Jordan DeLong. * 1.0.1 (April 14, 2010) Bug fixes: - Fix compilation when --enable-fill is specified. - Fix threads-related profiling bugs that affected accuracy and caused memory to be leaked during thread exit. - Fix dirty page purging race conditions that could cause crashes. - Fix crash in tcache flushing code during thread destruction. * 1.0.0 (April 11, 2010) This release focuses on speed and run-time introspection. Numerous algorithmic improvements make this release substantially faster than its predecessors. New features: - Implement autoconf-based configuration system. - Add mallctl*(), for the purposes of introspection and run-time configuration. - Make it possible for the application to manually flush a thread's cache, via the "tcache.flush" mallctl. - Base maximum dirty page count on proportion of active memory. - Compute various addtional run-time statistics, including per size class statistics for large objects. - Expose malloc_stats_print(), which can be called repeatedly by the application. - Simplify the malloc_message() signature to only take one string argument, and incorporate an opaque data pointer argument for use by the application in combination with malloc_stats_print(). - Add support for allocation backed by one or more swap files, and allow the application to disable over-commit if swap files are in use. - Implement allocation profiling and leak checking. Removed features: - Remove the dynamic arena rebalancing code, since thread-specific caching reduces its utility. Bug fixes: - Modify chunk allocation to work when address space layout randomization (ASLR) is in use. - Fix thread cleanup bugs related to TLS destruction. - Handle 0-size allocation requests in posix_memalign(). - Fix a chunk leak. The leaked chunks were never touched, so this impacted virtual memory usage, but not physical memory usage. * linux_2008082[78]a (August 27/28, 2008) These snapshot releases are the simple result of incorporating Linux-specific support into the FreeBSD malloc sources. -------------------------------------------------------------------------------- vim:filetype=text:textwidth=80 ================================================ FILE: extern/deprecated/redis-2.8.21/deps/jemalloc/INSTALL ================================================ Building and installing jemalloc can be as simple as typing the following while in the root directory of the source tree: ./configure make make install === Advanced configuration ===================================================== The 'configure' script supports numerous options that allow control of which functionality is enabled, where jemalloc is installed, etc. Optionally, pass any of the following arguments (not a definitive list) to 'configure': --help Print a definitive list of options. --prefix= Set the base directory in which to install. For example: ./configure --prefix=/usr/local will cause files to be installed into /usr/local/include, /usr/local/lib, and /usr/local/man. --with-rpath= Embed one or more library paths, so that libjemalloc can find the libraries it is linked to. This works only on ELF-based systems. --with-mangling= Mangle public symbols specified in which is a comma-separated list of name:mangled pairs. For example, to use ld's --wrap option as an alternative method for overriding libc's malloc implementation, specify something like: --with-mangling=malloc:__wrap_malloc,free:__wrap_free[...] Note that mangling happens prior to application of the prefix specified by --with-jemalloc-prefix, and mangled symbols are then ignored when applying the prefix. --with-jemalloc-prefix= Prefix all public APIs with . For example, if is "prefix_", API changes like the following occur: malloc() --> prefix_malloc() malloc_conf --> prefix_malloc_conf /etc/malloc.conf --> /etc/prefix_malloc.conf MALLOC_CONF --> PREFIX_MALLOC_CONF This makes it possible to use jemalloc at the same time as the system allocator, or even to use multiple copies of jemalloc simultaneously. By default, the prefix is "", except on OS X, where it is "je_". On OS X, jemalloc overlays the default malloc zone, but makes no attempt to actually replace the "malloc", "calloc", etc. symbols. --without-export Don't export public APIs. This can be useful when building jemalloc as a static library, or to avoid exporting public APIs when using the zone allocator on OSX. --with-private-namespace= Prefix all library-private APIs with je_. For shared libraries, symbol visibility mechanisms prevent these symbols from being exported, but for static libraries, naming collisions are a real possibility. By default, is empty, which results in a symbol prefix of je_ . --with-install-suffix= Append to the base name of all installed files, such that multiple versions of jemalloc can coexist in the same installation directory. For example, libjemalloc.so.0 becomes libjemalloc.so.0. --enable-cc-silence Enable code that silences non-useful compiler warnings. This is helpful when trying to tell serious warnings from those due to compiler limitations, but it potentially incurs a performance penalty. --enable-debug Enable assertions and validation code. This incurs a substantial performance hit, but is very useful during application development. Implies --enable-ivsalloc. --enable-code-coverage Enable code coverage support, for use during jemalloc test development. Additional testing targets are available if this option is enabled: coverage coverage_unit coverage_integration coverage_stress These targets do not clear code coverage results from previous runs, and there are interactions between the various coverage targets, so it is usually advisable to run 'make clean' between repeated code coverage runs. --enable-ivsalloc Enable validation code, which verifies that pointers reside within jemalloc-owned chunks before dereferencing them. This incurs a substantial performance hit. --disable-stats Disable statistics gathering functionality. See the "opt.stats_print" option documentation for usage details. --enable-prof Enable heap profiling and leak detection functionality. See the "opt.prof" option documentation for usage details. When enabled, there are several approaches to backtracing, and the configure script chooses the first one in the following list that appears to function correctly: + libunwind (requires --enable-prof-libunwind) + libgcc (unless --disable-prof-libgcc) + gcc intrinsics (unless --disable-prof-gcc) --enable-prof-libunwind Use the libunwind library (http://www.nongnu.org/libunwind/) for stack backtracing. --disable-prof-libgcc Disable the use of libgcc's backtracing functionality. --disable-prof-gcc Disable the use of gcc intrinsics for backtracing. --with-static-libunwind= Statically link against the specified libunwind.a rather than dynamically linking with -lunwind. --disable-tcache Disable thread-specific caches for small objects. Objects are cached and released in bulk, thus reducing the total number of mutex operations. See the "opt.tcache" option for usage details. --enable-mremap Enable huge realloc() via mremap(2). mremap() is disabled by default because the flavor used is specific to Linux, which has a quirk in its virtual memory allocation algorithm that causes semi-permanent VM map holes under normal jemalloc operation. --disable-munmap Disable virtual memory deallocation via munmap(2); instead keep track of the virtual memory for later use. munmap() is disabled by default (i.e. --disable-munmap is implied) on Linux, which has a quirk in its virtual memory allocation algorithm that causes semi-permanent VM map holes under normal jemalloc operation. --enable-dss Enable support for page allocation/deallocation via sbrk(2), in addition to mmap(2). --disable-fill Disable support for junk/zero filling of memory, quarantine, and redzones. See the "opt.junk", "opt.zero", "opt.quarantine", and "opt.redzone" option documentation for usage details. --disable-valgrind Disable support for Valgrind. --disable-experimental Disable support for the experimental API (*allocm()). --disable-zone-allocator Disable zone allocator for Darwin. This means jemalloc won't be hooked as the default allocator on OSX/iOS. --enable-utrace Enable utrace(2)-based allocation tracing. This feature is not broadly portable (FreeBSD has it, but Linux and OS X do not). --enable-xmalloc Enable support for optional immediate termination due to out-of-memory errors, as is commonly implemented by "xmalloc" wrapper function for malloc. See the "opt.xmalloc" option documentation for usage details. --enable-lazy-lock Enable code that wraps pthread_create() to detect when an application switches from single-threaded to multi-threaded mode, so that it can avoid mutex locking/unlocking operations while in single-threaded mode. In practice, this feature usually has little impact on performance unless thread-specific caching is disabled. --disable-tls Disable thread-local storage (TLS), which allows for fast access to thread-local variables via the __thread keyword. If TLS is available, jemalloc uses it for several purposes. --with-xslroot= Specify where to find DocBook XSL stylesheets when building the documentation. The following environment variables (not a definitive list) impact configure's behavior: CFLAGS="?" Pass these flags to the compiler. You probably shouldn't define this unless you know what you are doing. (Use EXTRA_CFLAGS instead.) EXTRA_CFLAGS="?" Append these flags to CFLAGS. This makes it possible to add flags such as -Werror, while allowing the configure script to determine what other flags are appropriate for the specified configuration. The configure script specifically checks whether an optimization flag (-O*) is specified in EXTRA_CFLAGS, and refrains from specifying an optimization level if it finds that one has already been specified. CPPFLAGS="?" Pass these flags to the C preprocessor. Note that CFLAGS is not passed to 'cpp' when 'configure' is looking for include files, so you must use CPPFLAGS instead if you need to help 'configure' find header files. LD_LIBRARY_PATH="?" 'ld' uses this colon-separated list to find libraries. LDFLAGS="?" Pass these flags when linking. PATH="?" 'configure' uses this to find programs. === Advanced compilation ======================================================= To build only parts of jemalloc, use the following targets: build_lib_shared build_lib_static build_lib build_doc_html build_doc_man build_doc To install only parts of jemalloc, use the following targets: install_bin install_include install_lib_shared install_lib_static install_lib install_doc_html install_doc_man install_doc To clean up build results to varying degrees, use the following make targets: clean distclean relclean === Advanced installation ====================================================== Optionally, define make variables when invoking make, including (not exclusively): INCLUDEDIR="?" Use this as the installation prefix for header files. LIBDIR="?" Use this as the installation prefix for libraries. MANDIR="?" Use this as the installation prefix for man pages. DESTDIR="?" Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR. This is useful when installing to a different path than was specified via --prefix. CC="?" Use this to invoke the C compiler. CFLAGS="?" Pass these flags to the compiler. CPPFLAGS="?" Pass these flags to the C preprocessor. LDFLAGS="?" Pass these flags when linking. PATH="?" Use this to search for programs used during configuration and building. === Development ================================================================ If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh' script rather than 'configure'. This re-generates 'configure', enables configuration dependency rules, and enables re-generation of automatically generated source files. The build system supports using an object directory separate from the source tree. For example, you can create an 'obj' directory, and from within that directory, issue configuration and build commands: autoconf mkdir obj cd obj ../configure --enable-autogen make === Documentation ============================================================== The manual page is generated in both html and roff formats. Any web browser can be used to view the html manual. The roff manual page can be formatted prior to installation via the following command: nroff -man -t doc/jemalloc.3 ================================================ FILE: extern/deprecated/redis-2.8.21/deps/jemalloc/Makefile.in ================================================ # Clear out all vpaths, then set just one (default vpath) for the main build # directory. vpath vpath % . # Clear the default suffixes, so that built-in rules are not used. .SUFFIXES : SHELL := /bin/sh CC := @CC@ # Configuration parameters.

In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling, Valgrind integration, and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release.

For instance: pprof http://myserver.com:80$HEAP_PAGE If / is omitted, the service defaults to $PROFILE_PAGE (cpu profiling). pprof --symbols Maps addresses to symbol names. In this mode, stdin should be a list of library mappings, in the same format as is found in the heap- and cpu-profile files (this loosely matches that of /proc/self/maps on linux), followed by a list of hex addresses to map, one per line.

The allocated space is suitably aligned (after possible pointer coercion) for storage of any type of object. The calloc function allocates space for number objects, each size bytes in length. The result is identical to calling malloc with an argument of number * size, with the exception that the allocated memory is explicitly initialized to zero bytes. The posix_memalign function allocates size bytes of memory such that the allocation's base address is an even multiple of alignment, and returns the allocation in the value pointed to by ptr. The requested alignment must be a power of 2 at least as large as sizeof(void *). The aligned_alloc function allocates size bytes of memory such that the allocation's base address is an even multiple of alignment. The requested alignment must be a power of 2. Behavior is undefined if size is not an integral multiple of alignment. The realloc function changes the size of the previously allocated memory referenced by ptr to size bytes. The contents of the memory are unchanged up to the lesser of the new and old sizes. If the new size is larger, the contents of the newly allocated portion of the memory are undefined. Upon success, the memory referenced by ptr is freed and a pointer to the newly allocated memory is returned. Note that realloc may move the memory allocation, resulting in a different return value than ptr. If ptr is NULL, the realloc function behaves identically to malloc for the specified size. The free function causes the allocated memory referenced by ptr to be made available for future allocations. If ptr is NULL, no action occurs. Non-standard API The mallocx, rallocx, xallocx, sallocx, dallocx, and nallocx functions all have a flags argument that can be used to specify options. The functions only check the options that are contextually relevant. Use bitwise or (|) operations to specify one or more of the following: MALLOCX_LG_ALIGN(la) Align the memory allocation to start at an address that is a multiple of (1 << la). This macro does not validate that la is within the valid range. MALLOCX_ALIGN(a) Align the memory allocation to start at an address that is a multiple of a, where a is a power of two. This macro does not validate that a is a power of 2. MALLOCX_ZERO Initialize newly allocated memory to contain zero bytes. In the growing reallocation case, the real size prior to reallocation defines the boundary between untouched bytes and those that are initialized to contain zero bytes. If this macro is absent, newly allocated memory is uninitialized. MALLOCX_ARENA(a) Use the arena specified by the index a (and by necessity bypass the thread cache). This macro has no effect for huge regions, nor for regions that were allocated via an arena other than the one specified. This macro does not validate that a specifies an arena index in the valid range. The mallocx function allocates at least size bytes of memory, and returns a pointer to the base address of the allocation. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The rallocx function resizes the allocation at ptr to be at least size bytes, and returns a pointer to the base address of the resulting allocation, which may or may not have moved from its original location. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The xallocx function resizes the allocation at ptr in place to be at least size bytes, and returns the real size of the allocation. If extra is non-zero, an attempt is made to resize the allocation to be at least (size + extra) bytes, though inability to allocate the extra byte(s) will not by itself result in failure to resize. Behavior is undefined if size is 0, or if (size + extra > SIZE_T_MAX). The sallocx function returns the real size of the allocation at ptr. The dallocx function causes the memory referenced by ptr to be made available for future allocations. The nallocx function allocates no memory, but it performs the same size computation as the mallocx function, and returns the real size of the allocation that would result from the equivalent mallocx function call. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The mallctl function provides a general interface for introspecting the memory allocator, as well as setting modifiable parameters and triggering actions. The period-separated name argument specifies a location in a tree-structured namespace; see the section for documentation on the tree contents. To read a value, pass a pointer via oldp to adequate space to contain the value, and a pointer to its length via oldlenp; otherwise pass NULL and NULL. Similarly, to write a value, pass a pointer to the value via newp, and its length via newlen; otherwise pass NULL and 0. The mallctlnametomib function provides a way to avoid repeated name lookups for applications that repeatedly query the same portion of the namespace, by translating a name to a “Management Information Base” (MIB) that can be passed repeatedly to mallctlbymib. Upon successful return from mallctlnametomib, mibp contains an array of *miblenp integers, where *miblenp is the lesser of the number of components in name and the input value of *miblenp. Thus it is possible to pass a *miblenp that is smaller than the number of period-separated name components, which results in a partial MIB that can be used as the basis for constructing a complete MIB. For name components that are integers (e.g. the 2 in arenas.bin.2.size), the corresponding MIB component will always be that integer. Therefore, it is legitimate to construct code like the following: The malloc_stats_print function writes human-readable summary statistics via the write_cb callback function pointer and cbopaque data passed to write_cb, or malloc_message if write_cb is NULL. This function can be called repeatedly. General information that never changes during execution can be omitted by specifying "g" as a character within the opts string. Note that malloc_message uses the mallctl* functions internally, so inconsistent statistics can be reported if multiple threads use these functions simultaneously. If is specified during configuration, “m” and “a” can be specified to omit merged arena and per arena statistics, respectively; “b” and “l” can be specified to omit per size class statistics for bins and large objects, respectively. Unrecognized characters are silently ignored. Note that thread caching may prevent some statistics from being completely up to date, since extra locking would be required to merge counters that track thread cache operations. The malloc_usable_size function returns the usable size of the allocation pointed to by ptr. The return value may be larger than the size that was requested during allocation. The malloc_usable_size function is not a mechanism for in-place realloc; rather it is provided solely as a tool for introspection purposes. Any discrepancy between the requested allocation size and the size reported by malloc_usable_size should not be depended on, since such behavior is entirely implementation-dependent. Experimental API The experimental API is subject to change or removal without regard for backward compatibility. If is specified during configuration, the experimental API is omitted. The allocm, rallocm, sallocm, dallocm, and nallocm functions all have a flags argument that can be used to specify options. The functions only check the options that are contextually relevant. Use bitwise or (|) operations to specify one or more of the following: ALLOCM_LG_ALIGN(la) Align the memory allocation to start at an address that is a multiple of (1 << la). This macro does not validate that la is within the valid range. ALLOCM_ALIGN(a) Align the memory allocation to start at an address that is a multiple of a, where a is a power of two. This macro does not validate that a is a power of 2. ALLOCM_ZERO Initialize newly allocated memory to contain zero bytes. In the growing reallocation case, the real size prior to reallocation defines the boundary between untouched bytes and those that are initialized to contain zero bytes. If this macro is absent, newly allocated memory is uninitialized. ALLOCM_NO_MOVE For reallocation, fail rather than moving the object. This constraint can apply to both growth and shrinkage. ALLOCM_ARENA(a) Use the arena specified by the index a (and by necessity bypass the thread cache). This macro has no effect for huge regions, nor for regions that were allocated via an arena other than the one specified. This macro does not validate that a specifies an arena index in the valid range. The allocm function allocates at least size bytes of memory, sets *ptr to the base address of the allocation, and sets *rsize to the real size of the allocation if rsize is not NULL. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The rallocm function resizes the allocation at *ptr to be at least size bytes, sets *ptr to the base address of the allocation if it moved, and sets *rsize to the real size of the allocation if rsize is not NULL. If extra is non-zero, an attempt is made to resize the allocation to be at least (size + extra) bytes, though inability to allocate the extra byte(s) will not by itself result in failure. Behavior is undefined if size is 0, if request size overflows due to size class and/or alignment constraints, or if (size + extra > SIZE_T_MAX). The sallocm function sets *rsize to the real size of the allocation. The dallocm function causes the memory referenced by ptr to be made available for future allocations. The nallocm function allocates no memory, but it performs the same size computation as the allocm function, and if rsize is not NULL it sets *rsize to the real size of the allocation that would result from the equivalent allocm function call. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. TUNING Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile- or run-time. The string pointed to by the global variable malloc_conf, the “name” of the file referenced by the symbolic link named /etc/malloc.conf, and the value of the environment variable MALLOC_CONF, will be interpreted, in that order, from left to right as options. Note that malloc_conf may be read before main is entered, so the declaration of malloc_conf should specify an initializer that contains the final value to be read by jemalloc. malloc_conf is a compile-time setting, whereas /etc/malloc.conf and MALLOC_CONF can be safely set any time prior to program invocation. An options string is a comma-separated list of option:value pairs. There is one key corresponding to each opt.* mallctl (see the section for options documentation). For example, abort:true,narenas:1 sets the opt.abort and opt.narenas options. Some options have boolean values (true/false), others have integer values (base 8, 10, or 16, depending on prefix), and yet others have raw string values. IMPLEMENTATION NOTES Traditionally, allocators have used sbrk 2 to obtain memory, which is suboptimal for several reasons, including race conditions, increased fragmentation, and artificial limitations on maximum usable memory. If is specified during configuration, this allocator uses both mmap 2 and sbrk 2, in that order of preference; otherwise only mmap 2 is used. This allocator uses multiple arenas in order to reduce lock contention for threaded programs on multi-processor systems. This works well with regard to threading scalability, but incurs some costs. There is a small fixed per-arena overhead, and additionally, arenas manage memory completely independently of each other, which means a small fixed increase in overall memory fragmentation. These overheads are not generally an issue, given the number of arenas normally used. Note that using substantially more arenas than the default is not likely to improve performance, mainly due to reduced cache performance. However, it may make sense to reduce the number of arenas if an application does not make much use of the allocation functions. In addition to multiple arenas, unless is specified during configuration, this allocator supports thread-specific caching for small and large objects, in order to make it possible to completely avoid synchronization for most allocation requests. Such caching allows very fast allocation in the common case, but it increases memory usage and fragmentation, since a bounded number of objects can remain allocated in each thread cache. Memory is conceptually broken into equal-sized chunks, where the chunk size is a power of two that is greater than the page size. Chunks are always aligned to multiples of the chunk size. This alignment makes it possible to find metadata for user objects very quickly. User objects are broken into three categories according to size: small, large, and huge. Small objects are smaller than one page. Large objects are smaller than the chunk size. Huge objects are a multiple of the chunk size. Small and large objects are managed by arenas; huge objects are managed separately in a single data structure that is shared by all threads. Huge objects are used by applications infrequently enough that this single data structure is not a scalability issue. Each chunk that is managed by an arena tracks its contents as runs of contiguous pages (unused, backing a set of small objects, or backing one large object). The combination of chunk alignment and chunk page maps makes it possible to determine all metadata regarding small and large allocations in constant time. Small objects are managed in groups by page runs. Each run maintains a frontier and free list to track which regions are in use. Allocation requests that are no more than half the quantum (8 or 16, depending on architecture) are rounded up to the nearest power of two that is at least sizeof(double). All other small object size classes are multiples of the quantum, spaced such that internal fragmentation is limited to approximately 25% for all but the smallest size classes. Allocation requests that are larger than the maximum small size class, but small enough to fit in an arena-managed chunk (see the opt.lg_chunk option), are rounded up to the nearest run size. Allocation requests that are too large to fit in an arena-managed chunk are rounded up to the nearest multiple of the chunk size. Allocations are packed tightly together, which can be an issue for multi-threaded applications. If you need to assure that allocations do not suffer from cacheline sharing, round your allocation requests up to the nearest multiple of the cacheline size, or specify cacheline alignment when allocating. Assuming 4 MiB chunks, 4 KiB pages, and a 16-byte quantum on a 64-bit system, the size classes in each category are as shown in .

MALLCTL NAMESPACE The following names are defined in the namespace accessible via the mallctl* functions. Value types are specified in parentheses, their readable/writable statuses are encoded as rw, r-, -w, or --, and required build configuration flags follow, if any. A name element encoded as <i> or <j> indicates an integer component, where the integer varies from 0 to some upper value that must be determined via introspection. In the case of stats.arenas.<i>.*, <i> equal to arenas.narenas can be used to access the summation of statistics from all arenas. Take special note of the epoch mallctl, which controls refreshing of cached dynamic statistics. version (const char *) r- Return the jemalloc version string. epoch (uint64_t) rw If a value is passed in, refresh the data from which the mallctl* functions report values, and increment the epoch. Return the current epoch. This is useful for detecting whether another thread caused a refresh. config.debug (bool) r- was specified during build configuration. config.dss (bool) r- was specified during build configuration. config.fill (bool) r- was specified during build configuration. config.lazy_lock (bool) r- was specified during build configuration. config.mremap (bool) r- was specified during build configuration. config.munmap (bool) r- was specified during build configuration. config.prof (bool) r- was specified during build configuration. config.prof_libgcc (bool) r- was not specified during build configuration. config.prof_libunwind (bool) r- was specified during build configuration. config.stats (bool) r- was specified during build configuration. config.tcache (bool) r- was not specified during build configuration. config.tls (bool) r- was not specified during build configuration. config.utrace (bool) r- was specified during build configuration. config.valgrind (bool) r- was specified during build configuration. config.xmalloc (bool) r- was specified during build configuration. opt.abort (bool) r- Abort-on-warning enabled/disabled. If true, most warnings are fatal. The process will call abort 3 in these cases. This option is disabled by default unless is specified during configuration, in which case it is enabled by default. opt.dss (const char *) r- dss (sbrk 2) allocation precedence as related to mmap 2 allocation. The following settings are supported: “disabled”, “primary”, and “secondary”. The default is “secondary” if config.dss is true, “disabled” otherwise. opt.lg_chunk (size_t) r- Virtual memory chunk size (log base 2). If a chunk size outside the supported size range is specified, the size is silently clipped to the minimum/maximum supported size. The default chunk size is 4 MiB (2^22). opt.narenas (size_t) r- Maximum number of arenas to use for automatic multiplexing of threads and arenas. The default is four times the number of CPUs, or one if there is a single CPU. opt.lg_dirty_mult (ssize_t) r- Per-arena minimum ratio (log base 2) of active to dirty pages. Some dirty unused pages may be allowed to accumulate, within the limit set by the ratio (or one chunk worth of dirty pages, whichever is greater), before informing the kernel about some of those pages via madvise 2 or a similar system call. This provides the kernel with sufficient information to recycle dirty pages if physical memory becomes scarce and the pages remain unused. The default minimum ratio is 8:1 (2^3:1); an option value of -1 will disable dirty page purging. opt.stats_print (bool) r- Enable/disable statistics printing at exit. If enabled, the malloc_stats_print function is called at program exit via an atexit 3 function. If is specified during configuration, this has the potential to cause deadlock for a multi-threaded process that exits while one or more threads are executing in the memory allocation functions. Therefore, this option should only be used with care; it is primarily intended as a performance tuning aid during application development. This option is disabled by default. opt.junk (bool) r- [] Junk filling enabled/disabled. If enabled, each byte of uninitialized allocated memory will be initialized to 0xa5. All deallocated memory will be initialized to 0x5a. This is intended for debugging and will impact performance negatively. This option is disabled by default unless is specified during configuration, in which case it is enabled by default unless running inside Valgrind. opt.quarantine (size_t) r- [] Per thread quarantine size in bytes. If non-zero, each thread maintains a FIFO object quarantine that stores up to the specified number of bytes of memory. The quarantined memory is not freed until it is released from quarantine, though it is immediately junk-filled if the opt.junk option is enabled. This feature is of particular use in combination with Valgrind, which can detect attempts to access quarantined objects. This is intended for debugging and will impact performance negatively. The default quarantine size is 0 unless running inside Valgrind, in which case the default is 16 MiB. opt.redzone (bool) r- [] Redzones enabled/disabled. If enabled, small allocations have redzones before and after them. Furthermore, if the opt.junk option is enabled, the redzones are checked for corruption during deallocation. However, the primary intended purpose of this feature is to be used in combination with Valgrind, which needs redzones in order to do effective buffer overflow/underflow detection. This option is intended for debugging and will impact performance negatively. This option is disabled by default unless running inside Valgrind. opt.zero (bool) r- [] Zero filling enabled/disabled. If enabled, each byte of uninitialized allocated memory will be initialized to 0. Note that this initialization only happens once for each byte, so realloc, rallocx and rallocm calls do not zero memory that was previously allocated. This is intended for debugging and will impact performance negatively. This option is disabled by default. opt.utrace (bool) r- [] Allocation tracing based on utrace 2 enabled/disabled. This option is disabled by default. opt.valgrind (bool) r- [] Valgrind support enabled/disabled. This option is vestigal because jemalloc auto-detects whether it is running inside Valgrind. This option is disabled by default, unless running inside Valgrind. opt.xmalloc (bool) r- [] Abort-on-out-of-memory enabled/disabled. If enabled, rather than returning failure for any allocation function, display a diagnostic message on STDERR_FILENO and cause the program to drop core (using abort 3). If an application is designed to depend on this behavior, set the option at compile time by including the following in the source code: This option is disabled by default. opt.tcache (bool) r- [] Thread-specific caching enabled/disabled. When there are multiple threads, each thread uses a thread-specific cache for objects up to a certain size. Thread-specific caching allows many allocations to be satisfied without performing any thread synchronization, at the cost of increased memory use. See the opt.lg_tcache_max option for related tuning information. This option is enabled by default unless running inside Valgrind. opt.lg_tcache_max (size_t) r- [] Maximum size class (log base 2) to cache in the thread-specific cache. At a minimum, all small size classes are cached, and at a maximum all large size classes are cached. The default maximum is 32 KiB (2^15). opt.prof (bool) r- [] Memory profiling enabled/disabled. If enabled, profile memory allocation activity. See the opt.prof_active option for on-the-fly activation/deactivation. See the opt.lg_prof_sample option for probabilistic sampling control. See the opt.prof_accum option for control of cumulative sample reporting. See the opt.lg_prof_interval option for information on interval-triggered profile dumping, the opt.prof_gdump option for information on high-water-triggered profile dumping, and the opt.prof_final option for final profile dumping. Profile output is compatible with the included pprof Perl script, which originates from the gperftools package. opt.prof_prefix (const char *) r- [] Filename prefix for profile dumps. If the prefix is set to the empty string, no automatic dumps will occur; this is primarily useful for disabling the automatic final heap dump (which also disables leak reporting, if enabled). The default prefix is jeprof. opt.prof_active (bool) rw [] Profiling activated/deactivated. This is a secondary control mechanism that makes it possible to start the application with profiling enabled (see the opt.prof option) but inactive, then toggle profiling at any time during program execution with the prof.active mallctl. This option is enabled by default. opt.lg_prof_sample (ssize_t) r- [] Average interval (log base 2) between allocation samples, as measured in bytes of allocation activity. Increasing the sampling interval decreases profile fidelity, but also decreases the computational overhead. The default sample interval is 512 KiB (2^19 B). opt.prof_accum (bool) r- [] Reporting of cumulative object/byte counts in profile dumps enabled/disabled. If this option is enabled, every unique backtrace must be stored for the duration of execution. Depending on the application, this can impose a large memory overhead, and the cumulative counts are not always of interest. This option is disabled by default. opt.lg_prof_interval (ssize_t) r- [] Average interval (log base 2) between memory profile dumps, as measured in bytes of allocation activity. The actual interval between dumps may be sporadic because decentralized allocation counters are used to avoid synchronization bottlenecks. Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.i<iseq>.heap, where <prefix> is controlled by the opt.prof_prefix option. By default, interval-triggered profile dumping is disabled (encoded as -1). opt.prof_gdump (bool) r- [] Trigger a memory profile dump every time the total virtual memory exceeds the previous maximum. Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.u<useq>.heap, where <prefix> is controlled by the opt.prof_prefix option. This option is disabled by default. opt.prof_final (bool) r- [] Use an atexit 3 function to dump final memory usage to a file named according to the pattern <prefix>.<pid>.<seq>.f.heap, where <prefix> is controlled by the opt.prof_prefix option. This option is enabled by default. opt.prof_leak (bool) r- [] Leak reporting enabled/disabled. If enabled, use an atexit 3 function to report memory leaks detected by allocation sampling. See the opt.prof option for information on analyzing heap profile output. This option is disabled by default. thread.arena (unsigned) rw Get or set the arena associated with the calling thread. If the specified arena was not initialized beforehand (see the arenas.initialized mallctl), it will be automatically initialized as a side effect of calling this interface. thread.allocated (uint64_t) r- [] Get the total number of bytes ever allocated by the calling thread. This counter has the potential to wrap around; it is up to the application to appropriately interpret the counter in such cases. thread.allocatedp (uint64_t *) r- [] Get a pointer to the the value that is returned by the thread.allocated mallctl. This is useful for avoiding the overhead of repeated mallctl* calls. thread.deallocated (uint64_t) r- [] Get the total number of bytes ever deallocated by the calling thread. This counter has the potential to wrap around; it is up to the application to appropriately interpret the counter in such cases. thread.deallocatedp (uint64_t *) r- [] Get a pointer to the the value that is returned by the thread.deallocated mallctl. This is useful for avoiding the overhead of repeated mallctl* calls. thread.tcache.enabled (bool) rw [] Enable/disable calling thread's tcache. The tcache is implicitly flushed as a side effect of becoming disabled (see thread.tcache.flush). thread.tcache.flush (void) -- [] Flush calling thread's tcache. This interface releases all cached objects and internal data structures associated with the calling thread's thread-specific cache. Ordinarily, this interface need not be called, since automatic periodic incremental garbage collection occurs, and the thread cache is automatically discarded when a thread exits. However, garbage collection is triggered by allocation activity, so it is possible for a thread that stops allocating/deallocating to retain its cache indefinitely, in which case the developer may find manual flushing useful. arena.<i>.purge (unsigned) -- Purge unused dirty pages for arena <i>, or for all arenas if <i> equals arenas.narenas. arena.<i>.dss (const char *) rw Set the precedence of dss allocation as related to mmap allocation for arena <i>, or for all arenas if <i> equals arenas.narenas. Note that even during huge allocation this setting is read from the arena that would be chosen for small or large allocation so that applications can depend on consistent dss versus mmap allocation regardless of allocation size. See opt.dss for supported settings. arenas.narenas (unsigned) r- Current limit on number of arenas. arenas.initialized (bool *) r- An array of arenas.narenas booleans. Each boolean indicates whether the corresponding arena is initialized. arenas.quantum (size_t) r- Quantum size. arenas.page (size_t) r- Page size. arenas.tcache_max (size_t) r- [] Maximum thread-cached size class. arenas.nbins (unsigned) r- Number of bin size classes. arenas.nhbins (unsigned) r- [] Total number of thread cache bin size classes. arenas.bin.<i>.size (size_t) r- Maximum size supported by size class. arenas.bin.<i>.nregs (uint32_t) r- Number of regions per page run. arenas.bin.<i>.run_size (size_t) r- Number of bytes per page run. arenas.nlruns (size_t) r- Total number of large size classes. arenas.lrun.<i>.size (size_t) r- Maximum size supported by this large size class. arenas.purge (unsigned) -w Purge unused dirty pages for the specified arena, or for all arenas if none is specified. arenas.extend (unsigned) r- Extend the array of arenas by appending a new arena, and returning the new arena index. prof.active (bool) rw [] Control whether sampling is currently active. See the opt.prof_active option for additional information. prof.dump (const char *) -w [] Dump a memory profile to the specified file, or if NULL is specified, to a file according to the pattern <prefix>.<pid>.<seq>.m<mseq>.heap, where <prefix> is controlled by the opt.prof_prefix option. prof.interval (uint64_t) r- [] Average number of bytes allocated between inverval-based profile dumps. See the opt.lg_prof_interval option for additional information. stats.cactive (size_t *) r- [] Pointer to a counter that contains an approximate count of the current number of bytes in active pages. The estimate may be high, but never low, because each arena rounds up to the nearest multiple of the chunk size when computing its contribution to the counter. Note that the epoch mallctl has no bearing on this counter. Furthermore, counter consistency is maintained via atomic operations, so it is necessary to use an atomic operation in order to guarantee a consistent read when dereferencing the pointer. stats.allocated (size_t) r- [] Total number of bytes allocated by the application. stats.active (size_t) r- [] Total number of bytes in active pages allocated by the application. This is a multiple of the page size, and greater than or equal to stats.allocated. This does not include stats.arenas.<i>.pdirty and pages entirely devoted to allocator metadata. stats.mapped (size_t) r- [] Total number of bytes in chunks mapped on behalf of the application. This is a multiple of the chunk size, and is at least as large as stats.active. This does not include inactive chunks. stats.chunks.current (size_t) r- [] Total number of chunks actively mapped on behalf of the application. This does not include inactive chunks. stats.chunks.total (uint64_t) r- [] Cumulative number of chunks allocated. stats.chunks.high (size_t) r- [] Maximum number of active chunks at any time thus far. stats.huge.allocated (size_t) r- [] Number of bytes currently allocated by huge objects. stats.huge.nmalloc (uint64_t) r- [] Cumulative number of huge allocation requests. stats.huge.ndalloc (uint64_t) r- [] Cumulative number of huge deallocation requests. stats.arenas.<i>.dss (const char *) r- dss (sbrk 2) allocation precedence as related to mmap 2 allocation. See opt.dss for details. stats.arenas.<i>.nthreads (unsigned) r- Number of threads currently assigned to arena. stats.arenas.<i>.pactive (size_t) r- Number of pages in active runs. stats.arenas.<i>.pdirty (size_t) r- Number of pages within unused runs that are potentially dirty, and for which madvise... MADV_DONTNEED or similar has not been called. stats.arenas.<i>.mapped (size_t) r- [] Number of mapped bytes. stats.arenas.<i>.npurge (uint64_t) r- [] Number of dirty page purge sweeps performed. stats.arenas.<i>.nmadvise (uint64_t) r- [] Number of madvise... MADV_DONTNEED or similar calls made to purge dirty pages. stats.arenas.<i>.purged (uint64_t) r- [] Number of pages purged. stats.arenas.<i>.small.allocated (size_t) r- [] Number of bytes currently allocated by small objects. stats.arenas.<i>.small.nmalloc (uint64_t) r- [] Cumulative number of allocation requests served by small bins. stats.arenas.<i>.small.ndalloc (uint64_t) r- [] Cumulative number of small objects returned to bins. stats.arenas.<i>.small.nrequests (uint64_t) r- [] Cumulative number of small allocation requests. stats.arenas.<i>.large.allocated (size_t) r- [] Number of bytes currently allocated by large objects. stats.arenas.<i>.large.nmalloc (uint64_t) r- [] Cumulative number of large allocation requests served directly by the arena. stats.arenas.<i>.large.ndalloc (uint64_t) r- [] Cumulative number of large deallocation requests served directly by the arena. stats.arenas.<i>.large.nrequests (uint64_t) r- [] Cumulative number of large allocation requests. stats.arenas.<i>.bins.<j>.allocated (size_t) r- [] Current number of bytes allocated by bin. stats.arenas.<i>.bins.<j>.nmalloc (uint64_t) r- [] Cumulative number of allocations served by bin. stats.arenas.<i>.bins.<j>.ndalloc (uint64_t) r- [] Cumulative number of allocations returned to bin. stats.arenas.<i>.bins.<j>.nrequests (uint64_t) r- [] Cumulative number of allocation requests. stats.arenas.<i>.bins.<j>.nfills (uint64_t) r- [ ] Cumulative number of tcache fills. stats.arenas.<i>.bins.<j>.nflushes (uint64_t) r- [ ] Cumulative number of tcache flushes. stats.arenas.<i>.bins.<j>.nruns (uint64_t) r- [] Cumulative number of runs created. stats.arenas.<i>.bins.<j>.nreruns (uint64_t) r- [] Cumulative number of times the current run from which to allocate changed. stats.arenas.<i>.bins.<j>.curruns (size_t) r- [] Current number of runs. stats.arenas.<i>.lruns.<j>.nmalloc (uint64_t) r- [] Cumulative number of allocation requests for this size class served directly by the arena. stats.arenas.<i>.lruns.<j>.ndalloc (uint64_t) r- [] Cumulative number of deallocation requests for this size class served directly by the arena. stats.arenas.<i>.lruns.<j>.nrequests (uint64_t) r- [] Cumulative number of allocation requests for this size class. stats.arenas.<i>.lruns.<j>.curruns (size_t) r- [] Current number of runs for this size class. DEBUGGING MALLOC PROBLEMS When debugging, it is a good idea to configure/build jemalloc with the and options, and recompile the program with suitable options and symbols for debugger support. When so configured, jemalloc incorporates a wide variety of run-time assertions that catch application errors such as double-free, write-after-free, etc. Programs often accidentally depend on “uninitialized” memory actually being filled with zero bytes. Junk filling (see the opt.junk option) tends to expose such bugs in the form of obviously incorrect results and/or coredumps. Conversely, zero filling (see the opt.zero option) eliminates the symptoms of such bugs. Between these two options, it is usually possible to quickly detect, diagnose, and eliminate such bugs. This implementation does not provide much detail about the problems it detects, because the performance impact for storing such information would be prohibitive. However, jemalloc does integrate with the most excellent Valgrind tool if the configuration option is enabled. DIAGNOSTIC MESSAGES If any of the memory allocation/deallocation functions detect an error or warning condition, a message will be printed to file descriptor STDERR_FILENO. Errors will result in the process dumping core. If the opt.abort option is set, most warnings are treated as errors. The malloc_message variable allows the programmer to override the function which emits the text strings forming the errors and warnings if for some reason the STDERR_FILENO file descriptor is not suitable for this. malloc_message takes the cbopaque pointer argument that is NULL unless overridden by the arguments in a call to malloc_stats_print, followed by a string pointer. Please note that doing anything which tries to allocate memory in this function is likely to result in a crash or deadlock. All messages are prefixed by “<jemalloc>: ”. RETURN VALUES Standard API The malloc and calloc functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set to ENOMEM. The posix_memalign function returns the value 0 if successful; otherwise it returns an error value. The posix_memalign function will fail if: EINVAL The alignment parameter is not a power of 2 at least as large as sizeof(void *). ENOMEM Memory allocation error. The aligned_alloc function returns a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set. The aligned_alloc function will fail if: EINVAL The alignment parameter is not a power of 2. ENOMEM Memory allocation error. The realloc function returns a pointer, possibly identical to ptr, to the allocated memory if successful; otherwise a NULL pointer is returned, and errno is set to ENOMEM if the error was the result of an allocation failure. The realloc function always leaves the original buffer intact when an error occurs. The free function returns no value. Non-standard API The mallocx and rallocx functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned to indicate insufficient contiguous memory was available to service the allocation request. The xallocx function returns the real size of the resulting resized allocation pointed to by ptr, which is a value less than size if the allocation could not be adequately grown in place. The sallocx function returns the real size of the allocation pointed to by ptr. The nallocx returns the real size that would result from a successful equivalent mallocx function call, or zero if insufficient memory is available to perform the size computation. The mallctl, mallctlnametomib, and mallctlbymib functions return 0 on success; otherwise they return an error value. The functions will fail if: EINVAL newp is not NULL, and newlen is too large or too small. Alternatively, *oldlenp is too large or too small; in this case as much data as possible are read despite the error. ENOENT name or mib specifies an unknown/invalid value. EPERM Attempt to read or write void value, or attempt to write read-only value. EAGAIN A memory allocation failure occurred. EFAULT An interface with side effects failed in some way not directly related to mallctl* read/write processing. The malloc_usable_size function returns the usable size of the allocation pointed to by ptr. Experimental API The allocm, rallocm, sallocm, dallocm, and nallocm functions return ALLOCM_SUCCESS on success; otherwise they return an error value. The allocm, rallocm, and nallocm functions will fail if: ALLOCM_ERR_OOM Out of memory. Insufficient contiguous memory was available to service the allocation request. The allocm function additionally sets *ptr to NULL, whereas the rallocm function leaves *ptr unmodified. The rallocm function will also fail if: ALLOCM_ERR_NOT_MOVED ALLOCM_NO_MOVE was specified, but the reallocation request could not be serviced without moving the object. ENVIRONMENT The following environment variable affects the execution of the allocation functions: MALLOC_CONF If the environment variable MALLOC_CONF is set, the characters it contains will be interpreted as options.

Line editing with some support for history is a really important feature for command line utilities. Instead of retyping almost the same stuff again and again it's just much better to hit the up arrow and edit on syntax errors, or in order to try a slightly different command. But apparently code dealing with terminals is some sort of Black Magic: readline is 30k lines of code, libedit 20k. Is it reasonable to link small utilities to huge libraries just to get a minimal support for line editing? So what usually happens is either: * Large programs with configure scripts disabling line editing if readline is not present in the system, or not supporting it at all since readline is GPL licensed and libedit (the BSD clone) is not as known and available as readline is (Real world example of this problem: Tclsh). * Smaller programs not using a configure script not supporting line editing at all (A problem we had with Redis-cli for instance). The result is a pollution of binaries without line editing support. So I spent more or less two hours doing a reality check resulting in this little library: is it *really* needed for a line editing library to be 20k lines of code? Apparently not, it is possibe to get a very small, zero configuration, trivial to embed library, that solves the problem. Smaller programs will just include this, supporing line editing out of the box. Larger programs may use this little library or just checking with configure if readline/libedit is available and resorting to linenoise if not. ## Terminals, in 2010. Apparently almost every terminal you can happen to use today has some kind of support for basic VT100 escape sequences. So I tried to write a lib using just very basic VT100 features. The resulting library appears to work everywhere I tried to use it, and now can work even on ANSI.SYS compatible terminals, since no VT220 specific sequences are used anymore. The library is currently about 1100 lines of code. In order to use it in your project just look at the *example.c* file in the source distribution, it is trivial. Linenoise is BSD code, so you can use both in free software and commercial software. ## Tested with... * Linux text only console ($TERM = linux) * Linux KDE terminal application ($TERM = xterm) * Linux xterm ($TERM = xterm) * Linux Buildroot ($TERM = vt100) * Mac OS X iTerm ($TERM = xterm) * Mac OS X default Terminal.app ($TERM = xterm) * OpenBSD 4.5 through an OSX Terminal.app ($TERM = screen) * IBM AIX 6.1 * FreeBSD xterm ($TERM = xterm) * ANSI.SYS Please test it everywhere you can and report back! ## Let's push this forward! Patches should be provided in the respect of linenoise sensibility for small easy to understand code.

Implementation: + new configuration scheme via luaconf.h. + incremental garbage collection. + better handling of end-of-line in the lexer. + fully reentrant parser (new Lua function `load') + better support for 64-bit machines. + native loadlib support for Mac OS X. + standard distribution in only one library (lualib.a merged into lua.a) * Changes from version 4.0 to 5.0 ------------------------------- Language: + lexical scoping. + Lua coroutines. + standard libraries now packaged in tables. + tags replaced by metatables and tag methods replaced by metamethods, stored in metatables. + proper tail calls. + each function can have its own global table, which can be shared. + new __newindex metamethod, called when we insert a new key into a table. + new block comments: --[[ ... ]]. + new generic for. + new weak tables. + new boolean type. + new syntax "local function". + (f()) returns the first value returned by f. + {f()} fills a table with all values returned by f. + \n ignored in [[\n . + fixed and-or priorities. + more general syntax for function definition (e.g. function a.x.y:f()...end). + more general syntax for function calls (e.g. (print or write)(9)). + new functions (time/date, tmpfile, unpack, require, load*, etc.). API: + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer. + introduced lightweight userdata, a simple "void*" without a metatable. + new error handling protocol: the core no longer prints error messages; all errors are reported to the caller on the stack. + new lua_atpanic for host cleanup. + new, signal-safe, hook scheme. Implementation: + new license: MIT. + new, faster, register-based virtual machine. + support for external multithreading and coroutines. + new and consistent error message format. + the core no longer needs "stdio.h" for anything (except for a single use of sprintf to convert numbers to strings). + lua.c now runs the environment variable LUA_INIT, if present. It can be "@filename", to run a file, or the chunk itself. + support for user extensions in lua.c. sample implementation given for command line editing. + new dynamic loading library, active by default on several platforms. + safe garbage-collector metamethods. + precompiled bytecodes checked for integrity (secure binary dostring). + strings are fully aligned. + position capture in string.find. + read('*l') can read lines with embedded zeros. * Changes from version 3.2 to 4.0 ------------------------------- Language: + new "break" and "for" statements (both numerical and for tables). + uniform treatment of globals: globals are now stored in a Lua table. + improved error messages. + no more '$debug': full speed *and* full debug information. + new read form: read(N) for next N bytes. + general read patterns now deprecated. (still available with -DCOMPAT_READPATTERNS.) + all return values are passed as arguments for the last function (old semantics still available with -DLUA_COMPAT_ARGRET) + garbage collection tag methods for tables now deprecated. + there is now only one tag method for order. API: + New API: fully re-entrant, simpler, and more efficient. + New debug API. Implementation: + faster than ever: cleaner virtual machine and new hashing algorithm. + non-recursive garbage-collector algorithm. + reduced memory usage for programs with many strings. + improved treatment for memory allocation errors. + improved support for 16-bit machines (we hope). + code now compiles unmodified as both ANSI C and C++. + numbers in bases other than 10 are converted using strtoul. + new -f option in Lua to support #! scripts. + luac can now combine text and binaries. * Changes from version 3.1 to 3.2 ------------------------------- + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT. + increased limit on the number of constants and globals per function (from 2^16 to 2^24). + debugging info (lua_debug and hooks) moved into lua_state and new API functions provided to get and set this info. + new debug lib gives full debugging access within Lua. + new table functions "foreachi", "sort", "tinsert", "tremove", "getn". + new io functions "flush", "seek". * Changes from version 3.0 to 3.1 ------------------------------- + NEW FEATURE: anonymous functions with closures (via "upvalues"). + new syntax: - local variables in chunks. - better scope control with DO block END. - constructors can now be also written: { record-part; list-part }. - more general syntax for function calls and lvalues, e.g.: f(x).y=1 o:f(x,y):g(z) f"string" is sugar for f("string") + strings may now contain arbitrary binary data (e.g., embedded zeros). + major code re-organization and clean-up; reduced module interdependecies. + no arbitrary limits on the total number of constants and globals. + support for multiple global contexts. + better syntax error messages. + new traversal functions "foreach" and "foreachvar". + the default for numbers is now double. changing it to use floats or longs is easy. + complete debug information stored in pre-compiled chunks. + sample interpreter now prompts user when run interactively, and also handles control-C interruptions gracefully. * Changes from version 2.5 to 3.0 ------------------------------- + NEW CONCEPT: "tag methods". Tag methods replace fallbacks as the meta-mechanism for extending the semantics of Lua. Whereas fallbacks had a global nature, tag methods work on objects having the same tag (e.g., groups of tables). Existing code that uses fallbacks should work without change. + new, general syntax for constructors {[exp] = exp, ... }. + support for handling variable number of arguments in functions (varargs). + support for conditional compilation ($if ... $else ... $end). + cleaner semantics in API simplifies host code. + better support for writing libraries (auxlib.h). + better type checking and error messages in the standard library. + luac can now also undump. * Changes from version 2.4 to 2.5 ------------------------------- + io and string libraries are now based on pattern matching; the old libraries are still available for compatibility + dofile and dostring can now return values (via return statement) + better support for 16- and 64-bit machines + expanded documentation, with more examples * Changes from version 2.2 to 2.4 ------------------------------- + external compiler creates portable binary files that can be loaded faster + interface for debugging and profiling + new "getglobal" fallback + new functions for handling references to Lua objects + new functions in standard lib + only one copy of each string is stored + expanded documentation, with more examples * Changes from version 2.1 to 2.2 ------------------------------- + functions now may be declared with any "lvalue" as a name + garbage collection of functions + support for pipes * Changes from version 1.1 to 2.1 ------------------------------- + object-oriented support + fallbacks + simplified syntax for tables + many internal improvements (end of HISTORY) ================================================ FILE: extern/deprecated/redis-2.8.21/deps/lua/INSTALL ================================================ INSTALL for Lua 5.1 * Building Lua ------------ Lua is built in the src directory, but the build process can be controlled from the top-level Makefile. Building Lua on Unix systems should be very easy. First do "make" and see if your platform is listed. If so, just do "make xxx", where xxx is your platform name. The platforms currently supported are: aix ansi bsd freebsd generic linux macosx mingw posix solaris If your platform is not listed, try the closest one or posix, generic, ansi, in this order. See below for customization instructions and for instructions on how to build with other Windows compilers. If you want to check that Lua has been built correctly, do "make test" after building Lua. Also, have a look at the example programs in test. * Installing Lua -------------- Once you have built Lua, you may want to install it in an official place in your system. In this case, do "make install". The official place and the way to install files are defined in Makefile. You must have the right permissions to install files. If you want to build and install Lua in one step, do "make xxx install", where xxx is your platform name. If you want to install Lua locally, then do "make local". This will create directories bin, include, lib, man, and install Lua there as follows: bin: lua luac include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp lib: liblua.a man/man1: lua.1 luac.1 These are the only directories you need for development. There are man pages for lua and luac, in both nroff and html, and a reference manual in html in doc, some sample code in test, and some useful stuff in etc. You don't need these directories for development. If you want to install Lua locally, but in some other directory, do "make install INSTALL_TOP=xxx", where xxx is your chosen directory. See below for instructions for Windows and other systems. * Customization ------------- Three things can be customized by editing a file: - Where and how to install Lua -- edit Makefile. - How to build Lua -- edit src/Makefile. - Lua features -- edit src/luaconf.h. You don't actually need to edit the Makefiles because you may set the relevant variables when invoking make. On the other hand, if you need to select some Lua features, you'll need to edit src/luaconf.h. The edited file will be the one installed, and it will be used by any Lua clients that you build, to ensure consistency. We strongly recommend that you enable dynamic loading. This is done automatically for all platforms listed above that have this feature (and also Windows). See src/luaconf.h and also src/Makefile. * Building Lua on Windows and other systems ----------------------------------------- If you're not using the usual Unix tools, then the instructions for building Lua depend on the compiler you use. You'll need to create projects (or whatever your compiler uses) for building the library, the interpreter, and the compiler, as follows: library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c ltm.c lundump.c lvm.c lzio.c lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c ltablib.c lstrlib.c loadlib.c linit.c interpreter: library, lua.c compiler: library, luac.c print.c If you use Visual Studio .NET, you can use etc/luavs.bat in its "Command Prompt". If all you want is to build the Lua interpreter, you may put all .c files in a single project, except for luac.c and print.c. Or just use etc/all.c. To use Lua as a library in your own programs, you'll need to know how to create and use libraries with your compiler. As mentioned above, you may edit luaconf.h to select some features before building Lua.

NAME

lua - Lua interpreter

SYNOPSIS

lua [ options ] [ script [ args ] ]

DESCRIPTION

lua is the stand-alone Lua interpreter. It loads and executes Lua programs, either in textual source form or in precompiled binary form. (Precompiled binaries are output by luac, the Lua compiler.) lua can be used as a batch interpreter and also interactively.

The given options (see below) are executed and then the Lua program in file script is loaded and executed. The given args are available to script as strings in a global table named arg. If these arguments contain spaces or other characters special to the shell, then they should be quoted (but note that the quotes will be removed by the shell). The arguments in arg start at 0, which contains the string 'script'. The index of the last argument is stored in arg.n. The arguments given in the command line before script, including the name of the interpreter, are available in negative indices in arg.

At the very start, before even handling the command line, lua executes the contents of the environment variable LUA_INIT, if it is defined. If the value of LUA_INIT is of the form '@filename', then filename is executed. Otherwise, the string is assumed to be a Lua statement and is executed.

Options start with '-' and are described below. You can use '--' to signal the end of options.

If no arguments are given, then "-v -i" is assumed when the standard input is a terminal; otherwise, "-" is assumed.

In interactive mode, lua prompts the user, reads lines from the standard input, and executes them as they are read. If a line does not contain a complete statement, then a secondary prompt is displayed and lines are read until a complete statement is formed or a syntax error is found. So, one way to interrupt the reading of an incomplete statement is to force a syntax error: adding a ';' in the middle of a statement is a sure way of forcing a syntax error (except inside multiline strings and comments; these must be closed explicitly). If a line starts with '=', then lua displays the values of all the expressions in the remainder of the line. The expressions must be separated by commas. The primary prompt is the value of the global variable _PROMPT, if this value is a string; otherwise, the default prompt is used. Similarly, the secondary prompt is the value of the global variable _PROMPT2. So, to change the prompts, set the corresponding variable to a string of your choice. You can do that after calling the interpreter or on the command line (but in this case you have to be careful with quotes if the prompt string contains a space; otherwise you may confuse the shell.) The default prompts are "> " and ">> ".

OPTIONS

- load and execute the standard input as a file, that is, not interactively, even when the standard input is a terminal.

-e stat execute statement stat. You need to quote stat if it contains spaces, quotes, or other characters special to the shell.

-i enter interactive mode after script is executed.

-l name call require('name') before executing script. Typically used to load libraries.

-v show version information.

NAME

luac - Lua compiler

SYNOPSIS

luac [ options ] [ filenames ]

DESCRIPTION

luac is the Lua compiler. It translates programs written in the Lua programming language into binary files that can be later loaded and executed.

The main advantages of precompiling chunks are: faster loading, protecting source code from accidental user changes, and off-line syntax checking.

Precompiling does not imply faster execution because in Lua chunks are always compiled into bytecodes before being executed. luac simply allows those bytecodes to be saved in a file for later execution.

Precompiled chunks are not necessarily smaller than the corresponding source. The main goal in precompiling is faster loading.

The binary files created by luac are portable only among architectures with the same word size and byte order.

luac produces a single output file containing the bytecodes for all source files given. By default, the output file is named luac.out, but you can change this with the -o option.

In the command line, you can mix text files containing Lua source and binary files containing precompiled chunks. This is useful because several precompiled chunks, even from different (but compatible) platforms, can be combined into a single precompiled chunk.

You can use '-' to indicate the standard input as a source file and '--' to signal the end of options (that is, all remaining arguments will be treated as files even if they start with '-').

The internal format of the binary files produced by luac is likely to change when a new version of Lua is released. So, save the source files of all Lua programs that you precompile.

OPTIONS

Options must be separate.

-l produce a listing of the compiled bytecode for Lua's virtual machine. Listing bytecodes is useful to learn about Lua's virtual machine. If no files are given, then luac loads luac.out and lists its contents.

-o file output to file, instead of the default luac.out. (You can use '-' for standard output, but not on platforms that open standard output in text mode.) The output file may be a source file because all files are loaded before the output file is written. Be careful not to overwrite precious files.

-p load files but do not generate any output file. Used mainly for syntax checking and for testing precompiled chunks: corrupted files will probably generate errors when loaded. Lua always performs a thorough integrity test on precompiled chunks. Bytecode that passes this test is completely safe, in the sense that it will not break the interpreter. However, there is no guarantee that such code does anything sensible. (None can be given, because the halting problem is unsolvable.) If no files are given, then luac loads luac.out and tests its contents. No messages are displayed if the file passes the integrity test.

-s strip debug information before writing the output file. This saves some space in very large chunks, but if errors occur when running a stripped chunk, then the error messages may not contain the full information they usually do. For instance, line numbers and names of local variables are lost.

-v show version information.

1 - Introduction

Lua is an extension programming language designed to support general procedural programming with data description facilities. It also offers good support for object-oriented programming, functional programming, and data-driven programming. Lua is intended to be used as a powerful, light-weight scripting language for any program that needs one. Lua is implemented as a library, written in clean C (that is, in the common subset of ANSI C and C++).

Being an extension language, Lua has no notion of a "main" program: it only works embedded in a host client, called the embedding program or simply the host. This host program can invoke functions to execute a piece of Lua code, can write and read Lua variables, and can register C functions to be called by Lua code. Through the use of C functions, Lua can be augmented to cope with a wide range of different domains, thus creating customized programming languages sharing a syntactical framework. The Lua distribution includes a sample host program called lua, which uses the Lua library to offer a complete, stand-alone Lua interpreter.

Lua is free software, and is provided as usual with no guarantees, as stated in its license. The implementation described in this manual is available at Lua's official web site, www.lua.org.

Like any other reference manual, this document is dry in places. For a discussion of the decisions behind the design of Lua, see the technical papers available at Lua's web site. For a detailed introduction to programming in Lua, see Roberto's book, Programming in Lua (Second Edition).

2 - The Language

This section describes the lexis, the syntax, and the semantics of Lua. In other words, this section describes which tokens are valid, how they can be combined, and what their combinations mean.

The language constructs will be explained using the usual extended BNF notation, in which {a} means 0 or more a's, and [a] means an optional a. Non-terminals are shown like non-terminal, keywords are shown like kword, and other terminal symbols are shown like `=´. The complete syntax of Lua can be found in §8 at the end of this manual.

2.1 - Lexical Conventions

Names (also called identifiers) in Lua can be any string of letters, digits, and underscores, not beginning with a digit. This coincides with the definition of names in most languages. (The definition of letter depends on the current locale: any character considered alphabetic by the current locale can be used in an identifier.) Identifiers are used to name variables and table fields.

The following keywords are reserved and cannot be used as names: 

     and       break     do        else      elseif
     end       false     for       function  if
     in        local     nil       not       or
     repeat    return    then      true      until     while

Lua is a case-sensitive language: and is a reserved word, but And and AND are two different, valid names. As a convention, names starting with an underscore followed by uppercase letters (such as _VERSION) are reserved for internal global variables used by Lua.

The following strings denote other tokens: 

     +     -     *     /     %     ^     #
     ==    ~=    <=    >=    <     >     =
     (     )     {     }     [     ]
     ;     :     ,     .     ..    ...

Literal strings can be delimited by matching single or double quotes, and can contain the following C-like escape sequences: '\a' (bell), '\b' (backspace), '\f' (form feed), '\n' (newline), '\r' (carriage return), '\t' (horizontal tab), '\v' (vertical tab), '\\' (backslash), '\"' (quotation mark [double quote]), and '\'' (apostrophe [single quote]). Moreover, a backslash followed by a real newline results in a newline in the string. A character in a string can also be specified by its numerical value using the escape sequence \ddd, where ddd is a sequence of up to three decimal digits. (Note that if a numerical escape is to be followed by a digit, it must be expressed using exactly three digits.) Strings in Lua can contain any 8-bit value, including embedded zeros, which can be specified as '\0'.

Literal strings can also be defined using a long format enclosed by long brackets. We define an opening long bracket of level n as an opening square bracket followed by n equal signs followed by another opening square bracket. So, an opening long bracket of level 0 is written as [[, an opening long bracket of level 1 is written as [=[, and so on. A closing long bracket is defined similarly; for instance, a closing long bracket of level 4 is written as ]====]. A long string starts with an opening long bracket of any level and ends at the first closing long bracket of the same level. Literals in this bracketed form can run for several lines, do not interpret any escape sequences, and ignore long brackets of any other level. They can contain anything except a closing bracket of the proper level.

For convenience, when the opening long bracket is immediately followed by a newline, the newline is not included in the string. As an example, in a system using ASCII (in which 'a' is coded as 97, newline is coded as 10, and '1' is coded as 49), the five literal strings below denote the same string: 

     a = 'alo\n123"'
     a = "alo\n123\""
     a = '\97lo\10\04923"'
     a = [[alo
     123"]]
     a = [==[
     alo
     123"]==]

A numerical constant can be written with an optional decimal part and an optional decimal exponent. Lua also accepts integer hexadecimal constants, by prefixing them with 0x. Examples of valid numerical constants are 

     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56

A comment starts with a double hyphen (--) anywhere outside a string. If the text immediately after -- is not an opening long bracket, the comment is a short comment, which runs until the end of the line. Otherwise, it is a long comment, which runs until the corresponding closing long bracket. Long comments are frequently used to disable code temporarily.

2.2 - Values and Types

Lua is a dynamically typed language. This means that variables do not have types; only values do. There are no type definitions in the language. All values carry their own type.

All values in Lua are first-class values. This means that all values can be stored in variables, passed as arguments to other functions, and returned as results.

There are eight basic types in Lua: nil, boolean, number, string, function, userdata, thread, and table. Nil is the type of the value nil, whose main property is to be different from any other value; it usually represents the absence of a useful value. Boolean is the type of the values false and true. Both nil and false make a condition false; any other value makes it true. Number represents real (double-precision floating-point) numbers. (It is easy to build Lua interpreters that use other internal representations for numbers, such as single-precision float or long integers; see file luaconf.h.) String represents arrays of characters. Lua is 8-bit clean: strings can contain any 8-bit character, including embedded zeros ('\0') (see §2.1).

Lua can call (and manipulate) functions written in Lua and functions written in C (see §2.5.8).

The type userdata is provided to allow arbitrary C data to be stored in Lua variables. This type corresponds to a block of raw memory and has no pre-defined operations in Lua, except assignment and identity test. However, by using metatables, the programmer can define operations for userdata values (see §2.8). Userdata values cannot be created or modified in Lua, only through the C API. This guarantees the integrity of data owned by the host program.

The type thread represents independent threads of execution and it is used to implement coroutines (see §2.11). Do not confuse Lua threads with operating-system threads. Lua supports coroutines on all systems, even those that do not support threads.

The type table implements associative arrays, that is, arrays that can be indexed not only with numbers, but with any value (except nil). Tables can be heterogeneous; that is, they can contain values of all types (except nil). Tables are the sole data structuring mechanism in Lua; they can be used to represent ordinary arrays, symbol tables, sets, records, graphs, trees, etc. To represent records, Lua uses the field name as an index. The language supports this representation by providing a.name as syntactic sugar for a["name"]. There are several convenient ways to create tables in Lua (see §2.5.7).

Like indices, the value of a table field can be of any type (except nil). In particular, because functions are first-class values, table fields can contain functions. Thus tables can also carry methods (see §2.5.9).

Tables, functions, threads, and (full) userdata values are objects: variables do not actually contain these values, only references to them. Assignment, parameter passing, and function returns always manipulate references to such values; these operations do not imply any kind of copy.

The library function type returns a string describing the type of a given value.

2.2.1 - Coercion

Lua provides automatic conversion between string and number values at run time. Any arithmetic operation applied to a string tries to convert this string to a number, following the usual conversion rules. Conversely, whenever a number is used where a string is expected, the number is converted to a string, in a reasonable format. For complete control over how numbers are converted to strings, use the format function from the string library (see string.format).

2.3 - Variables

Variables are places that store values. There are three kinds of variables in Lua: global variables, local variables, and table fields.

A single name can denote a global variable or a local variable (or a function's formal parameter, which is a particular kind of local variable): 

	var ::= Name

Name denotes identifiers, as defined in §2.1.

Any variable is assumed to be global unless explicitly declared as a local (see §2.4.7). Local variables are lexically scoped: local variables can be freely accessed by functions defined inside their scope (see §2.6).

Before the first assignment to a variable, its value is nil.

Square brackets are used to index a table: 

	var ::= prefixexp `[´ exp `]´

The meaning of accesses to global variables and table fields can be changed via metatables. An access to an indexed variable t[i] is equivalent to a call gettable_event(t,i). (See §2.8 for a complete description of the gettable_event function. This function is not defined or callable in Lua. We use it here only for explanatory purposes.)

The syntax var.Name is just syntactic sugar for var["Name"]: 

	var ::= prefixexp `.´ Name

All global variables live as fields in ordinary Lua tables, called environment tables or simply environments (see §2.9). Each function has its own reference to an environment, so that all global variables in this function will refer to this environment table. When a function is created, it inherits the environment from the function that created it. To get the environment table of a Lua function, you call getfenv. To replace it, you call setfenv. (You can only manipulate the environment of C functions through the debug library; (see §5.9).)

An access to a global variable x is equivalent to _env.x, which in turn is equivalent to 

     gettable_event(_env, "x")

where _env is the environment of the running function. (See §2.8 for a complete description of the gettable_event function. This function is not defined or callable in Lua. Similarly, the _env variable is not defined in Lua. We use them here only for explanatory purposes.)

2.4 - Statements

Lua supports an almost conventional set of statements, similar to those in Pascal or C. This set includes assignments, control structures, function calls, and variable declarations.

2.4.1 - Chunks

The unit of execution of Lua is called a chunk. A chunk is simply a sequence of statements, which are executed sequentially. Each statement can be optionally followed by a semicolon: 

	chunk ::= {stat [`;´]}

There are no empty statements and thus ';;' is not legal.

Lua handles a chunk as the body of an anonymous function with a variable number of arguments (see §2.5.9). As such, chunks can define local variables, receive arguments, and return values.

A chunk can be stored in a file or in a string inside the host program. To execute a chunk, Lua first pre-compiles the chunk into instructions for a virtual machine, and then it executes the compiled code with an interpreter for the virtual machine.

Chunks can also be pre-compiled into binary form; see program luac for details. Programs in source and compiled forms are interchangeable; Lua automatically detects the file type and acts accordingly.

2.4.2 - Blocks

A block is a list of statements; syntactically, a block is the same as a chunk: 

	block ::= chunk

A block can be explicitly delimited to produce a single statement: 

	stat ::= do block end

Explicit blocks are useful to control the scope of variable declarations. Explicit blocks are also sometimes used to add a return or break statement in the middle of another block (see §2.4.4).

2.4.3 - Assignment

Lua allows multiple assignments. Therefore, the syntax for assignment defines a list of variables on the left side and a list of expressions on the right side. The elements in both lists are separated by commas: 

	stat ::= varlist `=´ explist
	varlist ::= var {`,´ var}
	explist ::= exp {`,´ exp}

Expressions are discussed in §2.5.

Before the assignment, the list of values is adjusted to the length of the list of variables. If there are more values than needed, the excess values are thrown away. If there are fewer values than needed, the list is extended with as many nil's as needed. If the list of expressions ends with a function call, then all values returned by that call enter the list of values, before the adjustment (except when the call is enclosed in parentheses; see §2.5).

The assignment statement first evaluates all its expressions and only then are the assignments performed. Thus the code 

     i = 3
     i, a[i] = i+1, 20

sets a[3] to 20, without affecting a[4] because the i in a[i] is evaluated (to 3) before it is assigned 4. Similarly, the line 

     x, y = y, x

exchanges the values of x and y, and 

     x, y, z = y, z, x

cyclically permutes the values of x, y, and z.

The meaning of assignments to global variables and table fields can be changed via metatables. An assignment to an indexed variable t[i] = val is equivalent to settable_event(t,i,val). (See §2.8 for a complete description of the settable_event function. This function is not defined or callable in Lua. We use it here only for explanatory purposes.)

An assignment to a global variable x = val is equivalent to the assignment _env.x = val, which in turn is equivalent to 

     settable_event(_env, "x", val)

where _env is the environment of the running function. (The _env variable is not defined in Lua. We use it here only for explanatory purposes.)

2.4.4 - Control Structures

The control structures if, while, and repeat have the usual meaning and familiar syntax: 

	stat ::= while exp do block end
	stat ::= repeat block until exp
	stat ::= if exp then block {elseif exp then block} [else block] end

Lua also has a for statement, in two flavors (see §2.4.5).

The condition expression of a control structure can return any value. Both false and nil are considered false. All values different from nil and false are considered true (in particular, the number 0 and the empty string are also true).

In the repeat–until loop, the inner block does not end at the until keyword, but only after the condition. So, the condition can refer to local variables declared inside the loop block.

The return statement is used to return values from a function or a chunk (which is just a function). Functions and chunks can return more than one value, and so the syntax for the return statement is 

	stat ::= return [explist]

The break statement is used to terminate the execution of a while, repeat, or for loop, skipping to the next statement after the loop: 

	stat ::= break

A break ends the innermost enclosing loop.

The return and break statements can only be written as the last statement of a block. If it is really necessary to return or break in the middle of a block, then an explicit inner block can be used, as in the idioms do return end and do break end, because now return and break are the last statements in their (inner) blocks.

2.4.5 - For Statement

The for statement has two forms: one numeric and one generic.

The numeric for loop repeats a block of code while a control variable runs through an arithmetic progression. It has the following syntax: 

	stat ::= for Name `=´ exp `,´ exp [`,´ exp] do block end

The block is repeated for name starting at the value of the first exp, until it passes the second exp by steps of the third exp. More precisely, a for statement like 

     for v = e1, e2, e3 do block end

is equivalent to the code: 

     do
       local var, limit, step = tonumber(e1), tonumber(e2), tonumber(e3)
       if not (var and limit and step) then error() end
       while (step > 0 and var <= limit) or (step <= 0 and var >= limit) do
         local v = var
         block
         var = var + step
       end
     end

Note the following:

  • All three control expressions are evaluated only once, before the loop starts. They must all result in numbers.
  • var, limit, and step are invisible variables. The names shown here are for explanatory purposes only.
  • If the third expression (the step) is absent, then a step of 1 is used.
  • You can use break to exit a for loop.
  • The loop variable v is local to the loop; you cannot use its value after the for ends or is broken. If you need this value, assign it to another variable before breaking or exiting the loop.

The generic for statement works over functions, called iterators. On each iteration, the iterator function is called to produce a new value, stopping when this new value is nil. The generic for loop has the following syntax: 

	stat ::= for namelist in explist do block end
	namelist ::= Name {`,´ Name}

A for statement like 

     for var_1, ···, var_n in explist do block end

is equivalent to the code: 

     do
       local f, s, var = explist
       while true do
         local var_1, ···, var_n = f(s, var)
         var = var_1
         if var == nil then break end
         block
       end
     end

Note the following:

  • explist is evaluated only once. Its results are an iterator function, a state, and an initial value for the first iterator variable.
  • f, s, and var are invisible variables. The names are here for explanatory purposes only.
  • You can use break to exit a for loop.
  • The loop variables var_i are local to the loop; you cannot use their values after the for ends. If you need these values, then assign them to other variables before breaking or exiting the loop.

2.4.6 - Function Calls as Statements

To allow possible side-effects, function calls can be executed as statements: 

	stat ::= functioncall

In this case, all returned values are thrown away. Function calls are explained in §2.5.8.

2.4.7 - Local Declarations

Local variables can be declared anywhere inside a block. The declaration can include an initial assignment: 

	stat ::= local namelist [`=´ explist]

If present, an initial assignment has the same semantics of a multiple assignment (see §2.4.3). Otherwise, all variables are initialized with nil.

A chunk is also a block (see §2.4.1), and so local variables can be declared in a chunk outside any explicit block. The scope of such local variables extends until the end of the chunk.

The visibility rules for local variables are explained in §2.6.

2.5 - Expressions

The basic expressions in Lua are the following: 

	exp ::= prefixexp
	exp ::= nil | false | true
	exp ::= Number
	exp ::= String
	exp ::= function
	exp ::= tableconstructor
	exp ::= `...´
	exp ::= exp binop exp
	exp ::= unop exp
	prefixexp ::= var | functioncall | `(´ exp `)´

Numbers and literal strings are explained in §2.1; variables are explained in §2.3; function definitions are explained in §2.5.9; function calls are explained in §2.5.8; table constructors are explained in §2.5.7. Vararg expressions, denoted by three dots ('...'), can only be used when directly inside a vararg function; they are explained in §2.5.9.

Binary operators comprise arithmetic operators (see §2.5.1), relational operators (see §2.5.2), logical operators (see §2.5.3), and the concatenation operator (see §2.5.4). Unary operators comprise the unary minus (see §2.5.1), the unary not (see §2.5.3), and the unary length operator (see §2.5.5).

Both function calls and vararg expressions can result in multiple values. If an expression is used as a statement (only possible for function calls (see §2.4.6)), then its return list is adjusted to zero elements, thus discarding all returned values. If an expression is used as the last (or the only) element of a list of expressions, then no adjustment is made (unless the call is enclosed in parentheses). In all other contexts, Lua adjusts the result list to one element, discarding all values except the first one.

Here are some examples: 

     f()                -- adjusted to 0 results
     g(f(), x)          -- f() is adjusted to 1 result
     g(x, f())          -- g gets x plus all results from f()
     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
     a,b = ...          -- a gets the first vararg parameter, b gets
                        -- the second (both a and b can get nil if there
                        -- is no corresponding vararg parameter)
     
     a,b,c = x, f()     -- f() is adjusted to 2 results
     a,b,c = f()        -- f() is adjusted to 3 results
     return f()         -- returns all results from f()
     return ...         -- returns all received vararg parameters
     return x,y,f()     -- returns x, y, and all results from f()
     {f()}              -- creates a list with all results from f()
     {...}              -- creates a list with all vararg parameters
     {f(), nil}         -- f() is adjusted to 1 result

Any expression enclosed in parentheses always results in only one value. Thus, (f(x,y,z)) is always a single value, even if f returns several values. (The value of (f(x,y,z)) is the first value returned by f or nil if f does not return any values.)

2.5.1 - Arithmetic Operators

Lua supports the usual arithmetic operators: the binary + (addition), - (subtraction), * (multiplication), / (division), % (modulo), and ^ (exponentiation); and unary - (negation). If the operands are numbers, or strings that can be converted to numbers (see §2.2.1), then all operations have the usual meaning. Exponentiation works for any exponent. For instance, x^(-0.5) computes the inverse of the square root of x. Modulo is defined as 

     a % b == a - math.floor(a/b)*b

That is, it is the remainder of a division that rounds the quotient towards minus infinity.

2.5.2 - Relational Operators

The relational operators in Lua are 

     ==    ~=    <     >     <=    >=

These operators always result in false or true.

Equality (==) first compares the type of its operands. If the types are different, then the result is false. Otherwise, the values of the operands are compared. Numbers and strings are compared in the usual way. Objects (tables, userdata, threads, and functions) are compared by reference: two objects are considered equal only if they are the same object. Every time you create a new object (a table, userdata, thread, or function), this new object is different from any previously existing object.

You can change the way that Lua compares tables and userdata by using the "eq" metamethod (see §2.8).

The conversion rules of §2.2.1 do not apply to equality comparisons. Thus, "0"==0 evaluates to false, and t[0] and t["0"] denote different entries in a table.

The operator ~= is exactly the negation of equality (==).

The order operators work as follows. If both arguments are numbers, then they are compared as such. Otherwise, if both arguments are strings, then their values are compared according to the current locale. Otherwise, Lua tries to call the "lt" or the "le" metamethod (see §2.8). A comparison a > b is translated to b < a and a >= b is translated to b <= a.

2.5.3 - Logical Operators

The logical operators in Lua are and, or, and not. Like the control structures (see §2.4.4), all logical operators consider both false and nil as false and anything else as true.

The negation operator not always returns false or true. The conjunction operator and returns its first argument if this value is false or nil; otherwise, and returns its second argument. The disjunction operator or returns its first argument if this value is different from nil and false; otherwise, or returns its second argument. Both and and or use short-cut evaluation; that is, the second operand is evaluated only if necessary. Here are some examples: 

     10 or 20            --> 10
     10 or error()       --> 10
     nil or "a"          --> "a"
     nil and 10          --> nil
     false and error()   --> false
     false and nil       --> false
     false or nil        --> nil
     10 and 20           --> 20

(In this manual, --> indicates the result of the preceding expression.)

2.5.4 - Concatenation

The string concatenation operator in Lua is denoted by two dots ('..'). If both operands are strings or numbers, then they are converted to strings according to the rules mentioned in §2.2.1. Otherwise, the "concat" metamethod is called (see §2.8).

2.5.5 - The Length Operator

The length operator is denoted by the unary operator #. The length of a string is its number of bytes (that is, the usual meaning of string length when each character is one byte).

The length of a table t is defined to be any integer index n such that t[n] is not nil and t[n+1] is nil; moreover, if t[1] is nil, n can be zero. For a regular array, with non-nil values from 1 to a given n, its length is exactly that n, the index of its last value. If the array has "holes" (that is, nil values between other non-nil values), then #t can be any of the indices that directly precedes a nil value (that is, it may consider any such nil value as the end of the array).

2.5.6 - Precedence

Operator precedence in Lua follows the table below, from lower to higher priority: 

     or
     and
     <     >     <=    >=    ~=    ==
     ..
     +     -
     *     /     %
     not   #     - (unary)
     ^

As usual, you can use parentheses to change the precedences of an expression. The concatenation ('..') and exponentiation ('^') operators are right associative. All other binary operators are left associative.

2.5.7 - Table Constructors

Table constructors are expressions that create tables. Every time a constructor is evaluated, a new table is created. A constructor can be used to create an empty table or to create a table and initialize some of its fields. The general syntax for constructors is 

	tableconstructor ::= `{´ [fieldlist] `}´
	fieldlist ::= field {fieldsep field} [fieldsep]
	field ::= `[´ exp `]´ `=´ exp | Name `=´ exp | exp
	fieldsep ::= `,´ | `;´

Each field of the form [exp1] = exp2 adds to the new table an entry with key exp1 and value exp2. A field of the form name = exp is equivalent to ["name"] = exp. Finally, fields of the form exp are equivalent to [i] = exp, where i are consecutive numerical integers, starting with 1. Fields in the other formats do not affect this counting. For example, 

     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }

is equivalent to 

     do
       local t = {}
       t[f(1)] = g
       t[1] = "x"         -- 1st exp
       t[2] = "y"         -- 2nd exp
       t.x = 1            -- t["x"] = 1
       t[3] = f(x)        -- 3rd exp
       t[30] = 23
       t[4] = 45          -- 4th exp
       a = t
     end

If the last field in the list has the form exp and the expression is a function call or a vararg expression, then all values returned by this expression enter the list consecutively (see §2.5.8). To avoid this, enclose the function call or the vararg expression in parentheses (see §2.5).

The field list can have an optional trailing separator, as a convenience for machine-generated code.

2.5.8 - Function Calls

A function call in Lua has the following syntax: 

	functioncall ::= prefixexp args

In a function call, first prefixexp and args are evaluated. If the value of prefixexp has type function, then this function is called with the given arguments. Otherwise, the prefixexp "call" metamethod is called, having as first parameter the value of prefixexp, followed by the original call arguments (see §2.8).

The form 

	functioncall ::= prefixexp `:´ Name args

can be used to call "methods". A call v:name(args) is syntactic sugar for v.name(v,args), except that v is evaluated only once.

Arguments have the following syntax: 

	args ::= `(´ [explist] `)´
	args ::= tableconstructor
	args ::= String

All argument expressions are evaluated before the call. A call of the form f{fields} is syntactic sugar for f({fields}); that is, the argument list is a single new table. A call of the form f'string' (or f"string" or f[[string]]) is syntactic sugar for f('string'); that is, the argument list is a single literal string.

As an exception to the free-format syntax of Lua, you cannot put a line break before the '(' in a function call. This restriction avoids some ambiguities in the language. If you write 

     a = f
     (g).x(a)

Lua would see that as a single statement, a = f(g).x(a). So, if you want two statements, you must add a semi-colon between them. If you actually want to call f, you must remove the line break before (g).

A call of the form return functioncall is called a tail call. Lua implements proper tail calls (or proper tail recursion): in a tail call, the called function reuses the stack entry of the calling function. Therefore, there is no limit on the number of nested tail calls that a program can execute. However, a tail call erases any debug information about the calling function. Note that a tail call only happens with a particular syntax, where the return has one single function call as argument; this syntax makes the calling function return exactly the returns of the called function. So, none of the following examples are tail calls: 

     return (f(x))        -- results adjusted to 1
     return 2 * f(x)
     return x, f(x)       -- additional results
     f(x); return         -- results discarded
     return x or f(x)     -- results adjusted to 1

2.5.9 - Function Definitions

The syntax for function definition is 

	function ::= function funcbody
	funcbody ::= `(´ [parlist] `)´ block end

The following syntactic sugar simplifies function definitions: 

	stat ::= function funcname funcbody
	stat ::= local function Name funcbody
	funcname ::= Name {`.´ Name} [`:´ Name]

The statement 

     function f () body end

translates to 

     f = function () body end

The statement 

     function t.a.b.c.f () body end

translates to 

     t.a.b.c.f = function () body end

The statement 

     local function f () body end

translates to 

     local f; f = function () body end

not to 

     local f = function () body end

(This only makes a difference when the body of the function contains references to f.)

A function definition is an executable expression, whose value has type function. When Lua pre-compiles a chunk, all its function bodies are pre-compiled too. Then, whenever Lua executes the function definition, the function is instantiated (or closed). This function instance (or closure) is the final value of the expression. Different instances of the same function can refer to different external local variables and can have different environment tables.

Parameters act as local variables that are initialized with the argument values: 

	parlist ::= namelist [`,´ `...´] | `...´

When a function is called, the list of arguments is adjusted to the length of the list of parameters, unless the function is a variadic or vararg function, which is indicated by three dots ('...') at the end of its parameter list. A vararg function does not adjust its argument list; instead, it collects all extra arguments and supplies them to the function through a vararg expression, which is also written as three dots. The value of this expression is a list of all actual extra arguments, similar to a function with multiple results. If a vararg expression is used inside another expression or in the middle of a list of expressions, then its return list is adjusted to one element. If the expression is used as the last element of a list of expressions, then no adjustment is made (unless that last expression is enclosed in parentheses).

As an example, consider the following definitions: 

     function f(a, b) end
     function g(a, b, ...) end
     function r() return 1,2,3 end

Then, we have the following mapping from arguments to parameters and to the vararg expression: 

     CALL            PARAMETERS
     
     f(3)             a=3, b=nil
     f(3, 4)          a=3, b=4
     f(3, 4, 5)       a=3, b=4
     f(r(), 10)       a=1, b=10
     f(r())           a=1, b=2
     
     g(3)             a=3, b=nil, ... -->  (nothing)
     g(3, 4)          a=3, b=4,   ... -->  (nothing)
     g(3, 4, 5, 8)    a=3, b=4,   ... -->  5  8
     g(5, r())        a=5, b=1,   ... -->  2  3

Results are returned using the return statement (see §2.4.4). If control reaches the end of a function without encountering a return statement, then the function returns with no results.

The colon syntax is used for defining methods, that is, functions that have an implicit extra parameter self. Thus, the statement 

     function t.a.b.c:f (params) body end

is syntactic sugar for 

     t.a.b.c.f = function (self, params) body end

2.6 - Visibility Rules

Lua is a lexically scoped language. The scope of variables begins at the first statement after their declaration and lasts until the end of the innermost block that includes the declaration. Consider the following example: 

     x = 10                -- global variable
     do                    -- new block
       local x = x         -- new 'x', with value 10
       print(x)            --> 10
       x = x+1
       do                  -- another block
         local x = x+1     -- another 'x'
         print(x)          --> 12
       end
       print(x)            --> 11
     end
     print(x)              --> 10  (the global one)

Notice that, in a declaration like local x = x, the new x being declared is not in scope yet, and so the second x refers to the outside variable.

Because of the lexical scoping rules, local variables can be freely accessed by functions defined inside their scope. A local variable used by an inner function is called an upvalue, or external local variable, inside the inner function.

Notice that each execution of a local statement defines new local variables. Consider the following example: 

     a = {}
     local x = 20
     for i=1,10 do
       local y = 0
       a[i] = function () y=y+1; return x+y end
     end

The loop creates ten closures (that is, ten instances of the anonymous function). Each of these closures uses a different y variable, while all of them share the same x.

2.7 - Error Handling

Because Lua is an embedded extension language, all Lua actions start from C code in the host program calling a function from the Lua library (see lua_pcall). Whenever an error occurs during Lua compilation or execution, control returns to C, which can take appropriate measures (such as printing an error message).

Lua code can explicitly generate an error by calling the error function. If you need to catch errors in Lua, you can use the pcall function.

2.8 - Metatables

Every value in Lua can have a metatable. This metatable is an ordinary Lua table that defines the behavior of the original value under certain special operations. You can change several aspects of the behavior of operations over a value by setting specific fields in its metatable. For instance, when a non-numeric value is the operand of an addition, Lua checks for a function in the field "__add" in its metatable. If it finds one, Lua calls this function to perform the addition.

We call the keys in a metatable events and the values metamethods. In the previous example, the event is "add" and the metamethod is the function that performs the addition.

You can query the metatable of any value through the getmetatable function.

You can replace the metatable of tables through the setmetatable function. You cannot change the metatable of other types from Lua (except by using the debug library); you must use the C API for that.

Tables and full userdata have individual metatables (although multiple tables and userdata can share their metatables). Values of all other types share one single metatable per type; that is, there is one single metatable for all numbers, one for all strings, etc.

A metatable controls how an object behaves in arithmetic operations, order comparisons, concatenation, length operation, and indexing. A metatable also can define a function to be called when a userdata is garbage collected. For each of these operations Lua associates a specific key called an event. When Lua performs one of these operations over a value, it checks whether this value has a metatable with the corresponding event. If so, the value associated with that key (the metamethod) controls how Lua will perform the operation.

Metatables control the operations listed next. Each operation is identified by its corresponding name. The key for each operation is a string with its name prefixed by two underscores, '__'; for instance, the key for operation "add" is the string "__add". The semantics of these operations is better explained by a Lua function describing how the interpreter executes the operation.

The code shown here in Lua is only illustrative; the real behavior is hard coded in the interpreter and it is much more efficient than this simulation. All functions used in these descriptions (rawget, tonumber, etc.) are described in §5.1. In particular, to retrieve the metamethod of a given object, we use the expression 

     metatable(obj)[event]

This should be read as 

     rawget(getmetatable(obj) or {}, event)

That is, the access to a metamethod does not invoke other metamethods, and the access to objects with no metatables does not fail (it simply results in nil).

  • "add": the + operation.

    The function getbinhandler below defines how Lua chooses a handler for a binary operation. First, Lua tries the first operand. If its type does not define a handler for the operation, then Lua tries the second operand. 

         function getbinhandler (op1, op2, event)
       return metatable(op1)[event] or metatable(op2)[event]
     end

    By using this function, the behavior of the op1 + op2 is 

         function add_event (op1, op2)
       local o1, o2 = tonumber(op1), tonumber(op2)
       if o1 and o2 then  -- both operands are numeric?
         return o1 + o2   -- '+' here is the primitive 'add'
       else  -- at least one of the operands is not numeric
         local h = getbinhandler(op1, op2, "__add")
         if h then
           -- call the handler with both operands
           return (h(op1, op2))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

  • "sub": the - operation. Behavior similar to the "add" operation.
  • "mul": the * operation. Behavior similar to the "add" operation.
  • "div": the / operation. Behavior similar to the "add" operation.
  • "mod": the % operation. Behavior similar to the "add" operation, with the operation o1 - floor(o1/o2)*o2 as the primitive operation.
  • "pow": the ^ (exponentiation) operation. Behavior similar to the "add" operation, with the function pow (from the C math library) as the primitive operation.
  • "unm": the unary - operation. 
         function unm_event (op)
       local o = tonumber(op)
       if o then  -- operand is numeric?
         return -o  -- '-' here is the primitive 'unm'
       else  -- the operand is not numeric.
         -- Try to get a handler from the operand
         local h = metatable(op).__unm
         if h then
           -- call the handler with the operand
           return (h(op))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

  • "concat": the .. (concatenation) operation. 
         function concat_event (op1, op2)
       if (type(op1) == "string" or type(op1) == "number") and
          (type(op2) == "string" or type(op2) == "number") then
         return op1 .. op2  -- primitive string concatenation
       else
         local h = getbinhandler(op1, op2, "__concat")
         if h then
           return (h(op1, op2))
         else
           error(···)
         end
       end
     end

  • "len": the # operation. 
         function len_event (op)
       if type(op) == "string" then
         return strlen(op)         -- primitive string length
       elseif type(op) == "table" then
         return #op                -- primitive table length
       else
         local h = metatable(op).__len
         if h then
           -- call the handler with the operand
           return (h(op))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

    See §2.5.5 for a description of the length of a table.

  • "eq": the == operation. The function getcomphandler defines how Lua chooses a metamethod for comparison operators. A metamethod only is selected when both objects being compared have the same type and the same metamethod for the selected operation. 
         function getcomphandler (op1, op2, event)
       if type(op1) ~= type(op2) then return nil end
       local mm1 = metatable(op1)[event]
       local mm2 = metatable(op2)[event]
       if mm1 == mm2 then return mm1 else return nil end
     end

    The "eq" event is defined as follows: 

         function eq_event (op1, op2)
       if type(op1) ~= type(op2) then  -- different types?
         return false   -- different objects
       end
       if op1 == op2 then   -- primitive equal?
         return true   -- objects are equal
       end
       -- try metamethod
       local h = getcomphandler(op1, op2, "__eq")
       if h then
         return (h(op1, op2))
       else
         return false
       end
     end

    a ~= b is equivalent to not (a == b).

  • "lt": the < operation. 
         function lt_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 < op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 < op2   -- lexicographic comparison
       else
         local h = getcomphandler(op1, op2, "__lt")
         if h then
           return (h(op1, op2))
         else
           error(···)
         end
       end
     end

    a > b is equivalent to b < a.

  • "le": the <= operation. 
         function le_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 <= op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 <= op2   -- lexicographic comparison
       else
         local h = getcomphandler(op1, op2, "__le")
         if h then
           return (h(op1, op2))
         else
           h = getcomphandler(op1, op2, "__lt")
           if h then
             return not h(op2, op1)
           else
             error(···)
           end
         end
       end
     end

    a >= b is equivalent to b <= a. Note that, in the absence of a "le" metamethod, Lua tries the "lt", assuming that a <= b is equivalent to not (b < a).

  • "index": The indexing access table[key]. 
         function gettable_event (table, key)
       local h
       if type(table) == "table" then
         local v = rawget(table, key)
         if v ~= nil then return v end
         h = metatable(table).__index
         if h == nil then return nil end
       else
         h = metatable(table).__index
         if h == nil then
           error(···)
         end
       end
       if type(h) == "function" then
         return (h(table, key))     -- call the handler
       else return h[key]           -- or repeat operation on it
       end
     end

  • "newindex": The indexing assignment table[key] = value. 
         function settable_event (table, key, value)
       local h
       if type(table) == "table" then
         local v = rawget(table, key)
         if v ~= nil then rawset(table, key, value); return end
         h = metatable(table).__newindex
         if h == nil then rawset(table, key, value); return end
       else
         h = metatable(table).__newindex
         if h == nil then
           error(···)
         end
       end
       if type(h) == "function" then
         h(table, key,value)           -- call the handler
       else h[key] = value             -- or repeat operation on it
       end
     end

  • "call": called when Lua calls a value. 
         function function_event (func, ...)
       if type(func) == "function" then
         return func(...)   -- primitive call
       else
         local h = metatable(func).__call
         if h then
           return h(func, ...)
         else
           error(···)
         end
       end
     end

2.9 - Environments

Besides metatables, objects of types thread, function, and userdata have another table associated with them, called their environment. Like metatables, environments are regular tables and multiple objects can share the same environment.

Threads are created sharing the environment of the creating thread. Userdata and C functions are created sharing the environment of the creating C function. Non-nested Lua functions (created by loadfile, loadstring or load) are created sharing the environment of the creating thread. Nested Lua functions are created sharing the environment of the creating Lua function.

Environments associated with userdata have no meaning for Lua. It is only a convenience feature for programmers to associate a table to a userdata.

Environments associated with threads are called global environments. They are used as the default environment for threads and non-nested Lua functions created by the thread and can be directly accessed by C code (see §3.3).

The environment associated with a C function can be directly accessed by C code (see §3.3). It is used as the default environment for other C functions and userdata created by the function.

Environments associated with Lua functions are used to resolve all accesses to global variables within the function (see §2.3). They are used as the default environment for nested Lua functions created by the function.

You can change the environment of a Lua function or the running thread by calling setfenv. You can get the environment of a Lua function or the running thread by calling getfenv. To manipulate the environment of other objects (userdata, C functions, other threads) you must use the C API.

2.10 - Garbage Collection

Lua performs automatic memory management. This means that you have to worry neither about allocating memory for new objects nor about freeing it when the objects are no longer needed. Lua manages memory automatically by running a garbage collector from time to time to collect all dead objects (that is, objects that are no longer accessible from Lua). All memory used by Lua is subject to automatic management: tables, userdata, functions, threads, strings, etc.

Lua implements an incremental mark-and-sweep collector. It uses two numbers to control its garbage-collection cycles: the garbage-collector pause and the garbage-collector step multiplier. Both use percentage points as units (so that a value of 100 means an internal value of 1).

The garbage-collector pause controls how long the collector waits before starting a new cycle. Larger values make the collector less aggressive. Values smaller than 100 mean the collector will not wait to start a new cycle. A value of 200 means that the collector waits for the total memory in use to double before starting a new cycle.

The step multiplier controls the relative speed of the collector relative to memory allocation. Larger values make the collector more aggressive but also increase the size of each incremental step. Values smaller than 100 make the collector too slow and can result in the collector never finishing a cycle. The default, 200, means that the collector runs at "twice" the speed of memory allocation.

You can change these numbers by calling lua_gc in C or collectgarbage in Lua. With these functions you can also control the collector directly (e.g., stop and restart it).

2.10.1 - Garbage-Collection Metamethods

Using the C API, you can set garbage-collector metamethods for userdata (see §2.8). These metamethods are also called finalizers. Finalizers allow you to coordinate Lua's garbage collection with external resource management (such as closing files, network or database connections, or freeing your own memory).

Garbage userdata with a field __gc in their metatables are not collected immediately by the garbage collector. Instead, Lua puts them in a list. After the collection, Lua does the equivalent of the following function for each userdata in that list: 

     function gc_event (udata)
       local h = metatable(udata).__gc
       if h then
         h(udata)
       end
     end

At the end of each garbage-collection cycle, the finalizers for userdata are called in reverse order of their creation, among those collected in that cycle. That is, the first finalizer to be called is the one associated with the userdata created last in the program. The userdata itself is freed only in the next garbage-collection cycle.

2.10.2 - Weak Tables

A weak table is a table whose elements are weak references. A weak reference is ignored by the garbage collector. In other words, if the only references to an object are weak references, then the garbage collector will collect this object.

A weak table can have weak keys, weak values, or both. A table with weak keys allows the collection of its keys, but prevents the collection of its values. A table with both weak keys and weak values allows the collection of both keys and values. In any case, if either the key or the value is collected, the whole pair is removed from the table. The weakness of a table is controlled by the __mode field of its metatable. If the __mode field is a string containing the character 'k', the keys in the table are weak. If __mode contains 'v', the values in the table are weak.

After you use a table as a metatable, you should not change the value of its __mode field. Otherwise, the weak behavior of the tables controlled by this metatable is undefined.

2.11 - Coroutines

Lua supports coroutines, also called collaborative multithreading. A coroutine in Lua represents an independent thread of execution. Unlike threads in multithread systems, however, a coroutine only suspends its execution by explicitly calling a yield function.

You create a coroutine with a call to coroutine.create. Its sole argument is a function that is the main function of the coroutine. The create function only creates a new coroutine and returns a handle to it (an object of type thread); it does not start the coroutine execution.

When you first call coroutine.resume, passing as its first argument a thread returned by coroutine.create, the coroutine starts its execution, at the first line of its main function. Extra arguments passed to coroutine.resume are passed on to the coroutine main function. After the coroutine starts running, it runs until it terminates or yields.

A coroutine can terminate its execution in two ways: normally, when its main function returns (explicitly or implicitly, after the last instruction); and abnormally, if there is an unprotected error. In the first case, coroutine.resume returns true, plus any values returned by the coroutine main function. In case of errors, coroutine.resume returns false plus an error message.

A coroutine yields by calling coroutine.yield. When a coroutine yields, the corresponding coroutine.resume returns immediately, even if the yield happens inside nested function calls (that is, not in the main function, but in a function directly or indirectly called by the main function). In the case of a yield, coroutine.resume also returns true, plus any values passed to coroutine.yield. The next time you resume the same coroutine, it continues its execution from the point where it yielded, with the call to coroutine.yield returning any extra arguments passed to coroutine.resume.

Like coroutine.create, the coroutine.wrap function also creates a coroutine, but instead of returning the coroutine itself, it returns a function that, when called, resumes the coroutine. Any arguments passed to this function go as extra arguments to coroutine.resume. coroutine.wrap returns all the values returned by coroutine.resume, except the first one (the boolean error code). Unlike coroutine.resume, coroutine.wrap does not catch errors; any error is propagated to the caller.

As an example, consider the following code: 

     function foo (a)
       print("foo", a)
       return coroutine.yield(2*a)
     end
     
     co = coroutine.create(function (a,b)
           print("co-body", a, b)
           local r = foo(a+1)
           print("co-body", r)
           local r, s = coroutine.yield(a+b, a-b)
           print("co-body", r, s)
           return b, "end"
     end)
            
     print("main", coroutine.resume(co, 1, 10))
     print("main", coroutine.resume(co, "r"))
     print("main", coroutine.resume(co, "x", "y"))
     print("main", coroutine.resume(co, "x", "y"))

When you run it, it produces the following output: 

     co-body 1       10
     foo     2
     
     main    true    4
     co-body r
     main    true    11      -9
     co-body x       y
     main    true    10      end
     main    false   cannot resume dead coroutine

3 - The Application Program Interface

This section describes the C API for Lua, that is, the set of C functions available to the host program to communicate with Lua. All API functions and related types and constants are declared in the header file lua.h.

Even when we use the term "function", any facility in the API may be provided as a macro instead. All such macros use each of their arguments exactly once (except for the first argument, which is always a Lua state), and so do not generate any hidden side-effects.

As in most C libraries, the Lua API functions do not check their arguments for validity or consistency. However, you can change this behavior by compiling Lua with a proper definition for the macro luai_apicheck, in file luaconf.h.

3.1 - The Stack

Lua uses a virtual stack to pass values to and from C. Each element in this stack represents a Lua value (nil, number, string, etc.).

Whenever Lua calls C, the called function gets a new stack, which is independent of previous stacks and of stacks of C functions that are still active. This stack initially contains any arguments to the C function and it is where the C function pushes its results to be returned to the caller (see lua_CFunction).

For convenience, most query operations in the API do not follow a strict stack discipline. Instead, they can refer to any element in the stack by using an index: A positive index represents an absolute stack position (starting at 1); a negative index represents an offset relative to the top of the stack. More specifically, if the stack has n elements, then index 1 represents the first element (that is, the element that was pushed onto the stack first) and index n represents the last element; index -1 also represents the last element (that is, the element at the top) and index -n represents the first element. We say that an index is valid if it lies between 1 and the stack top (that is, if 1 ≤ abs(index) ≤ top).

3.2 - Stack Size

When you interact with Lua API, you are responsible for ensuring consistency. In particular, you are responsible for controlling stack overflow. You can use the function lua_checkstack to grow the stack size.

Whenever Lua calls C, it ensures that at least LUA_MINSTACK stack positions are available. LUA_MINSTACK is defined as 20, so that usually you do not have to worry about stack space unless your code has loops pushing elements onto the stack.

Most query functions accept as indices any value inside the available stack space, that is, indices up to the maximum stack size you have set through lua_checkstack. Such indices are called acceptable indices. More formally, we define an acceptable index as follows: 

     (index < 0 && abs(index) <= top) ||
     (index > 0 && index <= stackspace)

Note that 0 is never an acceptable index.

3.3 - Pseudo-Indices

Unless otherwise noted, any function that accepts valid indices can also be called with pseudo-indices, which represent some Lua values that are accessible to C code but which are not in the stack. Pseudo-indices are used to access the thread environment, the function environment, the registry, and the upvalues of a C function (see §3.4).

The thread environment (where global variables live) is always at pseudo-index LUA_GLOBALSINDEX. The environment of the running C function is always at pseudo-index LUA_ENVIRONINDEX.

To access and change the value of global variables, you can use regular table operations over an environment table. For instance, to access the value of a global variable, do 

     lua_getfield(L, LUA_GLOBALSINDEX, varname);

3.4 - C Closures

When a C function is created, it is possible to associate some values with it, thus creating a C closure; these values are called upvalues and are accessible to the function whenever it is called (see lua_pushcclosure).

Whenever a C function is called, its upvalues are located at specific pseudo-indices. These pseudo-indices are produced by the macro lua_upvalueindex. The first value associated with a function is at position lua_upvalueindex(1), and so on. Any access to lua_upvalueindex(n), where n is greater than the number of upvalues of the current function (but not greater than 256), produces an acceptable (but invalid) index.

3.5 - Registry

Lua provides a registry, a pre-defined table that can be used by any C code to store whatever Lua value it needs to store. This table is always located at pseudo-index LUA_REGISTRYINDEX. Any C library can store data into this table, but it should take care to choose keys different from those used by other libraries, to avoid collisions. Typically, you should use as key a string containing your library name or a light userdata with the address of a C object in your code.

The integer keys in the registry are used by the reference mechanism, implemented by the auxiliary library, and therefore should not be used for other purposes.

3.6 - Error Handling in C

Internally, Lua uses the C longjmp facility to handle errors. (You can also choose to use exceptions if you use C++; see file luaconf.h.) When Lua faces any error (such as memory allocation errors, type errors, syntax errors, and runtime errors) it raises an error; that is, it does a long jump. A protected environment uses setjmp to set a recover point; any error jumps to the most recent active recover point.

Most functions in the API can throw an error, for instance due to a memory allocation error. The documentation for each function indicates whether it can throw errors.

Inside a C function you can throw an error by calling lua_error.

3.7 - Functions and Types

Here we list all functions and types from the C API in alphabetical order. Each function has an indicator like this: [-o, +p, x]

The first field, o, is how many elements the function pops from the stack. The second field, p, is how many elements the function pushes onto the stack. (Any function always pushes its results after popping its arguments.) A field in the form x|y means the function can push (or pop) x or y elements, depending on the situation; an interrogation mark '?' means that we cannot know how many elements the function pops/pushes by looking only at its arguments (e.g., they may depend on what is on the stack). The third field, x, tells whether the function may throw errors: '-' means the function never throws any error; 'm' means the function may throw an error only due to not enough memory; 'e' means the function may throw other kinds of errors; 'v' means the function may throw an error on purpose.

lua_Alloc

typedef void * (*lua_Alloc) (void *ud,
                             void *ptr,
                             size_t osize,
                             size_t nsize);

The type of the memory-allocation function used by Lua states. The allocator function must provide a functionality similar to realloc, but not exactly the same. Its arguments are ud, an opaque pointer passed to lua_newstate; ptr, a pointer to the block being allocated/reallocated/freed; osize, the original size of the block; nsize, the new size of the block. ptr is NULL if and only if osize is zero. When nsize is zero, the allocator must return NULL; if osize is not zero, it should free the block pointed to by ptr. When nsize is not zero, the allocator returns NULL if and only if it cannot fill the request. When nsize is not zero and osize is zero, the allocator should behave like malloc. When nsize and osize are not zero, the allocator behaves like realloc. Lua assumes that the allocator never fails when osize >= nsize.

Here is a simple implementation for the allocator function. It is used in the auxiliary library by luaL_newstate. 

     static void *l_alloc (void *ud, void *ptr, size_t osize,
                                                size_t nsize) {
       (void)ud;  (void)osize;  /* not used */
       if (nsize == 0) {
         free(ptr);
         return NULL;
       }
       else
         return realloc(ptr, nsize);
     }

This code assumes that free(NULL) has no effect and that realloc(NULL, size) is equivalent to malloc(size). ANSI C ensures both behaviors.

lua_atpanic

[-0, +0, -] 

lua_CFunction lua_atpanic (lua_State *L, lua_CFunction panicf);

Sets a new panic function and returns the old one.

If an error happens outside any protected environment, Lua calls a panic function and then calls exit(EXIT_FAILURE), thus exiting the host application. Your panic function can avoid this exit by never returning (e.g., doing a long jump).

The panic function can access the error message at the top of the stack.

lua_call

[-(nargs + 1), +nresults, e] 

void lua_call (lua_State *L, int nargs, int nresults);

Calls a function.

To call a function you must use the following protocol: first, the function to be called is pushed onto the stack; then, the arguments to the function are pushed in direct order; that is, the first argument is pushed first. Finally you call lua_call; nargs is the number of arguments that you pushed onto the stack. All arguments and the function value are popped from the stack when the function is called. The function results are pushed onto the stack when the function returns. The number of results is adjusted to nresults, unless nresults is LUA_MULTRET. In this case, all results from the function are pushed. Lua takes care that the returned values fit into the stack space. The function results are pushed onto the stack in direct order (the first result is pushed first), so that after the call the last result is on the top of the stack.

Any error inside the called function is propagated upwards (with a longjmp).

The following example shows how the host program can do the equivalent to this Lua code: 

     a = f("how", t.x, 14)

Here it is in C: 

     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
     lua_pushstring(L, "how");                        /* 1st argument */
     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
     lua_remove(L, -2);                  /* remove 't' from the stack */
     lua_pushinteger(L, 14);                          /* 3rd argument */
     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */

Note that the code above is "balanced": at its end, the stack is back to its original configuration. This is considered good programming practice.

lua_CFunction

typedef int (*lua_CFunction) (lua_State *L);

Type for C functions.

In order to communicate properly with Lua, a C function must use the following protocol, which defines the way parameters and results are passed: a C function receives its arguments from Lua in its stack in direct order (the first argument is pushed first). So, when the function starts, lua_gettop(L) returns the number of arguments received by the function. The first argument (if any) is at index 1 and its last argument is at index lua_gettop(L). To return values to Lua, a C function just pushes them onto the stack, in direct order (the first result is pushed first), and returns the number of results. Any other value in the stack below the results will be properly discarded by Lua. Like a Lua function, a C function called by Lua can also return many results.

As an example, the following function receives a variable number of numerical arguments and returns their average and sum: 

     static int foo (lua_State *L) {
       int n = lua_gettop(L);    /* number of arguments */
       lua_Number sum = 0;
       int i;
       for (i = 1; i <= n; i++) {
         if (!lua_isnumber(L, i)) {
           lua_pushstring(L, "incorrect argument");
           lua_error(L);
         }
         sum += lua_tonumber(L, i);
       }
       lua_pushnumber(L, sum/n);        /* first result */
       lua_pushnumber(L, sum);         /* second result */
       return 2;                   /* number of results */
     }

lua_checkstack

[-0, +0, m] 

int lua_checkstack (lua_State *L, int extra);

Ensures that there are at least extra free stack slots in the stack. It returns false if it cannot grow the stack to that size. This function never shrinks the stack; if the stack is already larger than the new size, it is left unchanged.

lua_close

[-0, +0, -] 

void lua_close (lua_State *L);

Destroys all objects in the given Lua state (calling the corresponding garbage-collection metamethods, if any) and frees all dynamic memory used by this state. On several platforms, you may not need to call this function, because all resources are naturally released when the host program ends. On the other hand, long-running programs, such as a daemon or a web server, might need to release states as soon as they are not needed, to avoid growing too large.

lua_concat

[-n, +1, e] 

void lua_concat (lua_State *L, int n);

Concatenates the n values at the top of the stack, pops them, and leaves the result at the top. If n is 1, the result is the single value on the stack (that is, the function does nothing); if n is 0, the result is the empty string. Concatenation is performed following the usual semantics of Lua (see §2.5.4).

lua_cpcall

[-0, +(0|1), -] 

int lua_cpcall (lua_State *L, lua_CFunction func, void *ud);

Calls the C function func in protected mode. func starts with only one element in its stack, a light userdata containing ud. In case of errors, lua_cpcall returns the same error codes as lua_pcall, plus the error object on the top of the stack; otherwise, it returns zero, and does not change the stack. All values returned by func are discarded.

lua_createtable

[-0, +1, m] 

void lua_createtable (lua_State *L, int narr, int nrec);

Creates a new empty table and pushes it onto the stack. The new table has space pre-allocated for narr array elements and nrec non-array elements. This pre-allocation is useful when you know exactly how many elements the table will have. Otherwise you can use the function lua_newtable.

lua_dump

[-0, +0, m] 

int lua_dump (lua_State *L, lua_Writer writer, void *data);

Dumps a function as a binary chunk. Receives a Lua function on the top of the stack and produces a binary chunk that, if loaded again, results in a function equivalent to the one dumped. As it produces parts of the chunk, lua_dump calls function writer (see lua_Writer) with the given data to write them.

The value returned is the error code returned by the last call to the writer; 0 means no errors.

This function does not pop the Lua function from the stack.

lua_equal

[-0, +0, e] 

int lua_equal (lua_State *L, int index1, int index2);

Returns 1 if the two values in acceptable indices index1 and index2 are equal, following the semantics of the Lua == operator (that is, may call metamethods). Otherwise returns 0. Also returns 0 if any of the indices is non valid.

lua_error

[-1, +0, v] 

int lua_error (lua_State *L);

Generates a Lua error. The error message (which can actually be a Lua value of any type) must be on the stack top. This function does a long jump, and therefore never returns. (see luaL_error).

lua_gc

[-0, +0, e] 

int lua_gc (lua_State *L, int what, int data);

Controls the garbage collector.

This function performs several tasks, according to the value of the parameter what:

  • LUA_GCSTOP: stops the garbage collector.
  • LUA_GCRESTART: restarts the garbage collector.
  • LUA_GCCOLLECT: performs a full garbage-collection cycle.
  • LUA_GCCOUNT: returns the current amount of memory (in Kbytes) in use by Lua.
  • LUA_GCCOUNTB: returns the remainder of dividing the current amount of bytes of memory in use by Lua by 1024.
  • LUA_GCSTEP: performs an incremental step of garbage collection. The step "size" is controlled by data (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of data. The function returns 1 if the step finished a garbage-collection cycle.
  • LUA_GCSETPAUSE: sets data as the new value for the pause of the collector (see §2.10). The function returns the previous value of the pause.
  • LUA_GCSETSTEPMUL: sets data as the new value for the step multiplier of the collector (see §2.10). The function returns the previous value of the step multiplier.

lua_getallocf

[-0, +0, -] 

lua_Alloc lua_getallocf (lua_State *L, void **ud);

Returns the memory-allocation function of a given state. If ud is not NULL, Lua stores in *ud the opaque pointer passed to lua_newstate.

lua_getfenv

[-0, +1, -] 

void lua_getfenv (lua_State *L, int index);

Pushes onto the stack the environment table of the value at the given index.

lua_getfield

[-0, +1, e] 

void lua_getfield (lua_State *L, int index, const char *k);

Pushes onto the stack the value t[k], where t is the value at the given valid index. As in Lua, this function may trigger a metamethod for the "index" event (see §2.8).

lua_getglobal

[-0, +1, e] 

void lua_getglobal (lua_State *L, const char *name);

Pushes onto the stack the value of the global name. It is defined as a macro: 

     #define lua_getglobal(L,s)  lua_getfield(L, LUA_GLOBALSINDEX, s)

lua_getmetatable

[-0, +(0|1), -] 

int lua_getmetatable (lua_State *L, int index);

Pushes onto the stack the metatable of the value at the given acceptable index. If the index is not valid, or if the value does not have a metatable, the function returns 0 and pushes nothing on the stack.

lua_gettable

[-1, +1, e] 

void lua_gettable (lua_State *L, int index);

Pushes onto the stack the value t[k], where t is the value at the given valid index and k is the value at the top of the stack.

This function pops the key from the stack (putting the resulting value in its place). As in Lua, this function may trigger a metamethod for the "index" event (see §2.8).

lua_gettop

[-0, +0, -] 

int lua_gettop (lua_State *L);

Returns the index of the top element in the stack. Because indices start at 1, this result is equal to the number of elements in the stack (and so 0 means an empty stack).

lua_insert

[-1, +1, -] 

void lua_insert (lua_State *L, int index);

Moves the top element into the given valid index, shifting up the elements above this index to open space. Cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.

lua_Integer

typedef ptrdiff_t lua_Integer;

The type used by the Lua API to represent integral values.

By default it is a ptrdiff_t, which is usually the largest signed integral type the machine handles "comfortably".

lua_isboolean

[-0, +0, -] 

int lua_isboolean (lua_State *L, int index);

Returns 1 if the value at the given acceptable index has type boolean, and 0 otherwise.

lua_iscfunction

[-0, +0, -] 

int lua_iscfunction (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a C function, and 0 otherwise.

lua_isfunction

[-0, +0, -] 

int lua_isfunction (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a function (either C or Lua), and 0 otherwise.

lua_islightuserdata

[-0, +0, -] 

int lua_islightuserdata (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a light userdata, and 0 otherwise.

lua_isnil

[-0, +0, -] 

int lua_isnil (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is nil, and 0 otherwise.

lua_isnone

[-0, +0, -] 

int lua_isnone (lua_State *L, int index);

Returns 1 if the given acceptable index is not valid (that is, it refers to an element outside the current stack), and 0 otherwise.

lua_isnoneornil

[-0, +0, -] 

int lua_isnoneornil (lua_State *L, int index);

Returns 1 if the given acceptable index is not valid (that is, it refers to an element outside the current stack) or if the value at this index is nil, and 0 otherwise.

lua_isnumber

[-0, +0, -] 

int lua_isnumber (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a number or a string convertible to a number, and 0 otherwise.

lua_isstring

[-0, +0, -] 

int lua_isstring (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a string or a number (which is always convertible to a string), and 0 otherwise.

lua_istable

[-0, +0, -] 

int lua_istable (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a table, and 0 otherwise.

lua_isthread

[-0, +0, -] 

int lua_isthread (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a thread, and 0 otherwise.

lua_isuserdata

[-0, +0, -] 

int lua_isuserdata (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a userdata (either full or light), and 0 otherwise.

lua_lessthan

[-0, +0, e] 

int lua_lessthan (lua_State *L, int index1, int index2);

Returns 1 if the value at acceptable index index1 is smaller than the value at acceptable index index2, following the semantics of the Lua < operator (that is, may call metamethods). Otherwise returns 0. Also returns 0 if any of the indices is non valid.

lua_load

[-0, +1, -] 

int lua_load (lua_State *L,
              lua_Reader reader,
              void *data,
              const char *chunkname);

Loads a Lua chunk. If there are no errors, lua_load pushes the compiled chunk as a Lua function on top of the stack. Otherwise, it pushes an error message. The return values of lua_load are:

This function only loads a chunk; it does not run it.

lua_load automatically detects whether the chunk is text or binary, and loads it accordingly (see program luac).

The lua_load function uses a user-supplied reader function to read the chunk (see lua_Reader). The data argument is an opaque value passed to the reader function.

The chunkname argument gives a name to the chunk, which is used for error messages and in debug information (see §3.8).

lua_newstate

[-0, +0, -] 

lua_State *lua_newstate (lua_Alloc f, void *ud);

Creates a new, independent state. Returns NULL if cannot create the state (due to lack of memory). The argument f is the allocator function; Lua does all memory allocation for this state through this function. The second argument, ud, is an opaque pointer that Lua simply passes to the allocator in every call.

lua_newtable

[-0, +1, m] 

void lua_newtable (lua_State *L);

Creates a new empty table and pushes it onto the stack. It is equivalent to lua_createtable(L, 0, 0).

lua_newthread

[-0, +1, m] 

lua_State *lua_newthread (lua_State *L);

Creates a new thread, pushes it on the stack, and returns a pointer to a lua_State that represents this new thread. The new state returned by this function shares with the original state all global objects (such as tables), but has an independent execution stack.

There is no explicit function to close or to destroy a thread. Threads are subject to garbage collection, like any Lua object.

lua_newuserdata

[-0, +1, m] 

void *lua_newuserdata (lua_State *L, size_t size);

This function allocates a new block of memory with the given size, pushes onto the stack a new full userdata with the block address, and returns this address.

Userdata represent C values in Lua. A full userdata represents a block of memory. It is an object (like a table): you must create it, it can have its own metatable, and you can detect when it is being collected. A full userdata is only equal to itself (under raw equality).

When Lua collects a full userdata with a gc metamethod, Lua calls the metamethod and marks the userdata as finalized. When this userdata is collected again then Lua frees its corresponding memory.

lua_next

[-1, +(2|0), e] 

int lua_next (lua_State *L, int index);

Pops a key from the stack, and pushes a key-value pair from the table at the given index (the "next" pair after the given key). If there are no more elements in the table, then lua_next returns 0 (and pushes nothing).

A typical traversal looks like this: 

     /* table is in the stack at index 't' */
     lua_pushnil(L);  /* first key */
     while (lua_next(L, t) != 0) {
       /* uses 'key' (at index -2) and 'value' (at index -1) */
       printf("%s - %s\n",
              lua_typename(L, lua_type(L, -2)),
              lua_typename(L, lua_type(L, -1)));
       /* removes 'value'; keeps 'key' for next iteration */
       lua_pop(L, 1);
     }

While traversing a table, do not call lua_tolstring directly on a key, unless you know that the key is actually a string. Recall that lua_tolstring changes the value at the given index; this confuses the next call to lua_next.

lua_Number

typedef double lua_Number;

The type of numbers in Lua. By default, it is double, but that can be changed in luaconf.h.

Through the configuration file you can change Lua to operate with another type for numbers (e.g., float or long).

lua_objlen

[-0, +0, -] 

size_t lua_objlen (lua_State *L, int index);

Returns the "length" of the value at the given acceptable index: for strings, this is the string length; for tables, this is the result of the length operator ('#'); for userdata, this is the size of the block of memory allocated for the userdata; for other values, it is 0.

lua_pcall

[-(nargs + 1), +(nresults|1), -] 

int lua_pcall (lua_State *L, int nargs, int nresults, int errfunc);

Calls a function in protected mode.

Both nargs and nresults have the same meaning as in lua_call. If there are no errors during the call, lua_pcall behaves exactly like lua_call. However, if there is any error, lua_pcall catches it, pushes a single value on the stack (the error message), and returns an error code. Like lua_call, lua_pcall always removes the function and its arguments from the stack.

If errfunc is 0, then the error message returned on the stack is exactly the original error message. Otherwise, errfunc is the stack index of an error handler function. (In the current implementation, this index cannot be a pseudo-index.) In case of runtime errors, this function will be called with the error message and its return value will be the message returned on the stack by lua_pcall.

Typically, the error handler function is used to add more debug information to the error message, such as a stack traceback. Such information cannot be gathered after the return of lua_pcall, since by then the stack has unwound.

The lua_pcall function returns 0 in case of success or one of the following error codes (defined in lua.h):

  • LUA_ERRRUN: a runtime error.
  • LUA_ERRMEM: memory allocation error. For such errors, Lua does not call the error handler function.
  • LUA_ERRERR: error while running the error handler function.

lua_pop

[-n, +0, -] 

void lua_pop (lua_State *L, int n);

Pops n elements from the stack.

lua_pushboolean

[-0, +1, -] 

void lua_pushboolean (lua_State *L, int b);

Pushes a boolean value with value b onto the stack.

lua_pushcclosure

[-n, +1, m] 

void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);

Pushes a new C closure onto the stack.

When a C function is created, it is possible to associate some values with it, thus creating a C closure (see §3.4); these values are then accessible to the function whenever it is called. To associate values with a C function, first these values should be pushed onto the stack (when there are multiple values, the first value is pushed first). Then lua_pushcclosure is called to create and push the C function onto the stack, with the argument n telling how many values should be associated with the function. lua_pushcclosure also pops these values from the stack.

The maximum value for n is 255.

lua_pushcfunction

[-0, +1, m] 

void lua_pushcfunction (lua_State *L, lua_CFunction f);

Pushes a C function onto the stack. This function receives a pointer to a C function and pushes onto the stack a Lua value of type function that, when called, invokes the corresponding C function.

Any function to be registered in Lua must follow the correct protocol to receive its parameters and return its results (see lua_CFunction).

lua_pushcfunction is defined as a macro: 

     #define lua_pushcfunction(L,f)  lua_pushcclosure(L,f,0)

lua_pushfstring

[-0, +1, m] 

const char *lua_pushfstring (lua_State *L, const char *fmt, ...);

Pushes onto the stack a formatted string and returns a pointer to this string. It is similar to the C function sprintf, but has some important differences:

  • You do not have to allocate space for the result: the result is a Lua string and Lua takes care of memory allocation (and deallocation, through garbage collection).
  • The conversion specifiers are quite restricted. There are no flags, widths, or precisions. The conversion specifiers can only be '%%' (inserts a '%' in the string), '%s' (inserts a zero-terminated string, with no size restrictions), '%f' (inserts a lua_Number), '%p' (inserts a pointer as a hexadecimal numeral), '%d' (inserts an int), and '%c' (inserts an int as a character).

lua_pushinteger

[-0, +1, -] 

void lua_pushinteger (lua_State *L, lua_Integer n);

Pushes a number with value n onto the stack.

lua_pushlightuserdata

[-0, +1, -] 

void lua_pushlightuserdata (lua_State *L, void *p);

Pushes a light userdata onto the stack.

Userdata represent C values in Lua. A light userdata represents a pointer. It is a value (like a number): you do not create it, it has no individual metatable, and it is not collected (as it was never created). A light userdata is equal to "any" light userdata with the same C address.

lua_pushliteral

[-0, +1, m] 

void lua_pushliteral (lua_State *L, const char *s);

This macro is equivalent to lua_pushlstring, but can be used only when s is a literal string. In these cases, it automatically provides the string length.

lua_pushlstring

[-0, +1, m] 

void lua_pushlstring (lua_State *L, const char *s, size_t len);

Pushes the string pointed to by s with size len onto the stack. Lua makes (or reuses) an internal copy of the given string, so the memory at s can be freed or reused immediately after the function returns. The string can contain embedded zeros.

lua_pushnil

[-0, +1, -] 

void lua_pushnil (lua_State *L);

Pushes a nil value onto the stack.

lua_pushnumber

[-0, +1, -] 

void lua_pushnumber (lua_State *L, lua_Number n);

Pushes a number with value n onto the stack.

lua_pushstring

[-0, +1, m] 

void lua_pushstring (lua_State *L, const char *s);

Pushes the zero-terminated string pointed to by s onto the stack. Lua makes (or reuses) an internal copy of the given string, so the memory at s can be freed or reused immediately after the function returns. The string cannot contain embedded zeros; it is assumed to end at the first zero.

lua_pushthread

[-0, +1, -] 

int lua_pushthread (lua_State *L);

Pushes the thread represented by L onto the stack. Returns 1 if this thread is the main thread of its state.

lua_pushvalue

[-0, +1, -] 

void lua_pushvalue (lua_State *L, int index);

Pushes a copy of the element at the given valid index onto the stack.

lua_pushvfstring

[-0, +1, m] 

const char *lua_pushvfstring (lua_State *L,
                              const char *fmt,
                              va_list argp);

Equivalent to lua_pushfstring, except that it receives a va_list instead of a variable number of arguments.

lua_rawequal

[-0, +0, -] 

int lua_rawequal (lua_State *L, int index1, int index2);

Returns 1 if the two values in acceptable indices index1 and index2 are primitively equal (that is, without calling metamethods). Otherwise returns 0. Also returns 0 if any of the indices are non valid.

lua_rawget

[-1, +1, -] 

void lua_rawget (lua_State *L, int index);

Similar to lua_gettable, but does a raw access (i.e., without metamethods).

lua_rawgeti

[-0, +1, -] 

void lua_rawgeti (lua_State *L, int index, int n);

Pushes onto the stack the value t[n], where t is the value at the given valid index. The access is raw; that is, it does not invoke metamethods.

lua_rawset

[-2, +0, m] 

void lua_rawset (lua_State *L, int index);

Similar to lua_settable, but does a raw assignment (i.e., without metamethods).

lua_rawseti

[-1, +0, m] 

void lua_rawseti (lua_State *L, int index, int n);

Does the equivalent of t[n] = v, where t is the value at the given valid index and v is the value at the top of the stack.

This function pops the value from the stack. The assignment is raw; that is, it does not invoke metamethods.

lua_Reader

typedef const char * (*lua_Reader) (lua_State *L,
                                    void *data,
                                    size_t *size);

The reader function used by lua_load. Every time it needs another piece of the chunk, lua_load calls the reader, passing along its data parameter. The reader must return a pointer to a block of memory with a new piece of the chunk and set size to the block size. The block must exist until the reader function is called again. To signal the end of the chunk, the reader must return NULL or set size to zero. The reader function may return pieces of any size greater than zero.

lua_register

[-0, +0, e] 

void lua_register (lua_State *L,
                   const char *name,
                   lua_CFunction f);

Sets the C function f as the new value of global name. It is defined as a macro: 

     #define lua_register(L,n,f) \
            (lua_pushcfunction(L, f), lua_setglobal(L, n))

lua_remove

[-1, +0, -] 

void lua_remove (lua_State *L, int index);

Removes the element at the given valid index, shifting down the elements above this index to fill the gap. Cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.

lua_replace

[-1, +0, -] 

void lua_replace (lua_State *L, int index);

Moves the top element into the given position (and pops it), without shifting any element (therefore replacing the value at the given position).

lua_resume

[-?, +?, -] 

int lua_resume (lua_State *L, int narg);

Starts and resumes a coroutine in a given thread.

To start a coroutine, you first create a new thread (see lua_newthread); then you push onto its stack the main function plus any arguments; then you call lua_resume, with narg being the number of arguments. This call returns when the coroutine suspends or finishes its execution. When it returns, the stack contains all values passed to lua_yield, or all values returned by the body function. lua_resume returns LUA_YIELD if the coroutine yields, 0 if the coroutine finishes its execution without errors, or an error code in case of errors (see lua_pcall). In case of errors, the stack is not unwound, so you can use the debug API over it. The error message is on the top of the stack. To restart a coroutine, you put on its stack only the values to be passed as results from yield, and then call lua_resume.

lua_setallocf

[-0, +0, -] 

void lua_setallocf (lua_State *L, lua_Alloc f, void *ud);

Changes the allocator function of a given state to f with user data ud.

lua_setfenv

[-1, +0, -] 

int lua_setfenv (lua_State *L, int index);

Pops a table from the stack and sets it as the new environment for the value at the given index. If the value at the given index is neither a function nor a thread nor a userdata, lua_setfenv returns 0. Otherwise it returns 1.

lua_setfield

[-1, +0, e] 

void lua_setfield (lua_State *L, int index, const char *k);

Does the equivalent to t[k] = v, where t is the value at the given valid index and v is the value at the top of the stack.

This function pops the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event (see §2.8).

lua_setglobal

[-1, +0, e] 

void lua_setglobal (lua_State *L, const char *name);

Pops a value from the stack and sets it as the new value of global name. It is defined as a macro: 

     #define lua_setglobal(L,s)   lua_setfield(L, LUA_GLOBALSINDEX, s)

lua_setmetatable

[-1, +0, -] 

int lua_setmetatable (lua_State *L, int index);

Pops a table from the stack and sets it as the new metatable for the value at the given acceptable index.

lua_settable

[-2, +0, e] 

void lua_settable (lua_State *L, int index);

Does the equivalent to t[k] = v, where t is the value at the given valid index, v is the value at the top of the stack, and k is the value just below the top.

This function pops both the key and the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event (see §2.8).

lua_settop

[-?, +?, -] 

void lua_settop (lua_State *L, int index);

Accepts any acceptable index, or 0, and sets the stack top to this index. If the new top is larger than the old one, then the new elements are filled with nil. If index is 0, then all stack elements are removed.

lua_State

typedef struct lua_State lua_State;

Opaque structure that keeps the whole state of a Lua interpreter. The Lua library is fully reentrant: it has no global variables. All information about a state is kept in this structure.

A pointer to this state must be passed as the first argument to every function in the library, except to lua_newstate, which creates a Lua state from scratch.

lua_status

[-0, +0, -] 

int lua_status (lua_State *L);

Returns the status of the thread L.

The status can be 0 for a normal thread, an error code if the thread finished its execution with an error, or LUA_YIELD if the thread is suspended.

lua_toboolean

[-0, +0, -] 

int lua_toboolean (lua_State *L, int index);

Converts the Lua value at the given acceptable index to a C boolean value (0 or 1). Like all tests in Lua, lua_toboolean returns 1 for any Lua value different from false and nil; otherwise it returns 0. It also returns 0 when called with a non-valid index. (If you want to accept only actual boolean values, use lua_isboolean to test the value's type.)

lua_tocfunction

[-0, +0, -] 

lua_CFunction lua_tocfunction (lua_State *L, int index);

Converts a value at the given acceptable index to a C function. That value must be a C function; otherwise, returns NULL.

lua_tointeger

[-0, +0, -] 

lua_Integer lua_tointeger (lua_State *L, int index);

Converts the Lua value at the given acceptable index to the signed integral type lua_Integer. The Lua value must be a number or a string convertible to a number (see §2.2.1); otherwise, lua_tointeger returns 0.

If the number is not an integer, it is truncated in some non-specified way.

lua_tolstring

[-0, +0, m] 

const char *lua_tolstring (lua_State *L, int index, size_t *len);

Converts the Lua value at the given acceptable index to a C string. If len is not NULL, it also sets *len with the string length. The Lua value must be a string or a number; otherwise, the function returns NULL. If the value is a number, then lua_tolstring also changes the actual value in the stack to a string. (This change confuses lua_next when lua_tolstring is applied to keys during a table traversal.)

lua_tolstring returns a fully aligned pointer to a string inside the Lua state. This string always has a zero ('\0') after its last character (as in C), but can contain other zeros in its body. Because Lua has garbage collection, there is no guarantee that the pointer returned by lua_tolstring will be valid after the corresponding value is removed from the stack.

lua_tonumber

[-0, +0, -] 

lua_Number lua_tonumber (lua_State *L, int index);

Converts the Lua value at the given acceptable index to the C type lua_Number (see lua_Number). The Lua value must be a number or a string convertible to a number (see §2.2.1); otherwise, lua_tonumber returns 0.

lua_topointer

[-0, +0, -] 

const void *lua_topointer (lua_State *L, int index);

Converts the value at the given acceptable index to a generic C pointer (void*). The value can be a userdata, a table, a thread, or a function; otherwise, lua_topointer returns NULL. Different objects will give different pointers. There is no way to convert the pointer back to its original value.

Typically this function is used only for debug information.

lua_tostring

[-0, +0, m] 

const char *lua_tostring (lua_State *L, int index);

Equivalent to lua_tolstring with len equal to NULL.

lua_tothread

[-0, +0, -] 

lua_State *lua_tothread (lua_State *L, int index);

Converts the value at the given acceptable index to a Lua thread (represented as lua_State*). This value must be a thread; otherwise, the function returns NULL.

lua_touserdata

[-0, +0, -] 

void *lua_touserdata (lua_State *L, int index);

If the value at the given acceptable index is a full userdata, returns its block address. If the value is a light userdata, returns its pointer. Otherwise, returns NULL.

lua_type

[-0, +0, -] 

int lua_type (lua_State *L, int index);

Returns the type of the value in the given acceptable index, or LUA_TNONE for a non-valid index (that is, an index to an "empty" stack position). The types returned by lua_type are coded by the following constants defined in lua.h: LUA_TNIL, LUA_TNUMBER, LUA_TBOOLEAN, LUA_TSTRING, LUA_TTABLE, LUA_TFUNCTION, LUA_TUSERDATA, LUA_TTHREAD, and LUA_TLIGHTUSERDATA.

lua_typename

[-0, +0, -] 

const char *lua_typename  (lua_State *L, int tp);

Returns the name of the type encoded by the value tp, which must be one the values returned by lua_type.

lua_Writer

typedef int (*lua_Writer) (lua_State *L,
                           const void* p,
                           size_t sz,
                           void* ud);

The type of the writer function used by lua_dump. Every time it produces another piece of chunk, lua_dump calls the writer, passing along the buffer to be written (p), its size (sz), and the data parameter supplied to lua_dump.

The writer returns an error code: 0 means no errors; any other value means an error and stops lua_dump from calling the writer again.

lua_xmove

[-?, +?, -] 

void lua_xmove (lua_State *from, lua_State *to, int n);

Exchange values between different threads of the same global state.

This function pops n values from the stack from, and pushes them onto the stack to.

lua_yield

[-?, +?, -] 

int lua_yield  (lua_State *L, int nresults);

Yields a coroutine.

This function should only be called as the return expression of a C function, as follows: 

     return lua_yield (L, nresults);

When a C function calls lua_yield in that way, the running coroutine suspends its execution, and the call to lua_resume that started this coroutine returns. The parameter nresults is the number of values from the stack that are passed as results to lua_resume.

3.8 - The Debug Interface

Lua has no built-in debugging facilities. Instead, it offers a special interface by means of functions and hooks. This interface allows the construction of different kinds of debuggers, profilers, and other tools that need "inside information" from the interpreter.

lua_Debug

typedef struct lua_Debug {
  int event;
  const char *name;           /* (n) */
  const char *namewhat;       /* (n) */
  const char *what;           /* (S) */
  const char *source;         /* (S) */
  int currentline;            /* (l) */
  int nups;                   /* (u) number of upvalues */
  int linedefined;            /* (S) */
  int lastlinedefined;        /* (S) */
  char short_src[LUA_IDSIZE]; /* (S) */
  /* private part */
  other fields
} lua_Debug;

A structure used to carry different pieces of information about an active function. lua_getstack fills only the private part of this structure, for later use. To fill the other fields of lua_Debug with useful information, call lua_getinfo.

The fields of lua_Debug have the following meaning:

  • source: If the function was defined in a string, then source is that string. If the function was defined in a file, then source starts with a '@' followed by the file name.
  • short_src: a "printable" version of source, to be used in error messages.
  • linedefined: the line number where the definition of the function starts.
  • lastlinedefined: the line number where the definition of the function ends.
  • what: the string "Lua" if the function is a Lua function, "C" if it is a C function, "main" if it is the main part of a chunk, and "tail" if it was a function that did a tail call. In the latter case, Lua has no other information about the function.
  • currentline: the current line where the given function is executing. When no line information is available, currentline is set to -1.
  • name: a reasonable name for the given function. Because functions in Lua are first-class values, they do not have a fixed name: some functions can be the value of multiple global variables, while others can be stored only in a table field. The lua_getinfo function checks how the function was called to find a suitable name. If it cannot find a name, then name is set to NULL.
  • namewhat: explains the name field. The value of namewhat can be "global", "local", "method", "field", "upvalue", or "" (the empty string), according to how the function was called. (Lua uses the empty string when no other option seems to apply.)
  • nups: the number of upvalues of the function.

lua_gethook

[-0, +0, -] 

lua_Hook lua_gethook (lua_State *L);

Returns the current hook function.

lua_gethookcount

[-0, +0, -] 

int lua_gethookcount (lua_State *L);

Returns the current hook count.

lua_gethookmask

[-0, +0, -] 

int lua_gethookmask (lua_State *L);

Returns the current hook mask.

lua_getinfo

[-(0|1), +(0|1|2), m] 

int lua_getinfo (lua_State *L, const char *what, lua_Debug *ar);

Returns information about a specific function or function invocation.

To get information about a function invocation, the parameter ar must be a valid activation record that was filled by a previous call to lua_getstack or given as argument to a hook (see lua_Hook).

To get information about a function you push it onto the stack and start the what string with the character '>'. (In that case, lua_getinfo pops the function in the top of the stack.) For instance, to know in which line a function f was defined, you can write the following code: 

     lua_Debug ar;
     lua_getfield(L, LUA_GLOBALSINDEX, "f");  /* get global 'f' */
     lua_getinfo(L, ">S", &ar);
     printf("%d\n", ar.linedefined);

Each character in the string what selects some fields of the structure ar to be filled or a value to be pushed on the stack:

  • 'n': fills in the field name and namewhat;
  • 'S': fills in the fields source, short_src, linedefined, lastlinedefined, and what;
  • 'l': fills in the field currentline;
  • 'u': fills in the field nups;
  • 'f': pushes onto the stack the function that is running at the given level;
  • 'L': pushes onto the stack a table whose indices are the numbers of the lines that are valid on the function. (A valid line is a line with some associated code, that is, a line where you can put a break point. Non-valid lines include empty lines and comments.)

This function returns 0 on error (for instance, an invalid option in what).

lua_getlocal

[-0, +(0|1), -] 

const char *lua_getlocal (lua_State *L, lua_Debug *ar, int n);

Gets information about a local variable of a given activation record. The parameter ar must be a valid activation record that was filled by a previous call to lua_getstack or given as argument to a hook (see lua_Hook). The index n selects which local variable to inspect (1 is the first parameter or active local variable, and so on, until the last active local variable). lua_getlocal pushes the variable's value onto the stack and returns its name.

Variable names starting with '(' (open parentheses) represent internal variables (loop control variables, temporaries, and C function locals).

Returns NULL (and pushes nothing) when the index is greater than the number of active local variables.

lua_getstack

[-0, +0, -] 

int lua_getstack (lua_State *L, int level, lua_Debug *ar);

Get information about the interpreter runtime stack.

This function fills parts of a lua_Debug structure with an identification of the activation record of the function executing at a given level. Level 0 is the current running function, whereas level n+1 is the function that has called level n. When there are no errors, lua_getstack returns 1; when called with a level greater than the stack depth, it returns 0.

lua_getupvalue

[-0, +(0|1), -] 

const char *lua_getupvalue (lua_State *L, int funcindex, int n);

Gets information about a closure's upvalue. (For Lua functions, upvalues are the external local variables that the function uses, and that are consequently included in its closure.) lua_getupvalue gets the index n of an upvalue, pushes the upvalue's value onto the stack, and returns its name. funcindex points to the closure in the stack. (Upvalues have no particular order, as they are active through the whole function. So, they are numbered in an arbitrary order.)

Returns NULL (and pushes nothing) when the index is greater than the number of upvalues. For C functions, this function uses the empty string "" as a name for all upvalues.

lua_Hook

typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);

Type for debugging hook functions.

Whenever a hook is called, its ar argument has its field event set to the specific event that triggered the hook. Lua identifies these events with the following constants: LUA_HOOKCALL, LUA_HOOKRET, LUA_HOOKTAILRET, LUA_HOOKLINE, and LUA_HOOKCOUNT. Moreover, for line events, the field currentline is also set. To get the value of any other field in ar, the hook must call lua_getinfo. For return events, event can be LUA_HOOKRET, the normal value, or LUA_HOOKTAILRET. In the latter case, Lua is simulating a return from a function that did a tail call; in this case, it is useless to call lua_getinfo.

While Lua is running a hook, it disables other calls to hooks. Therefore, if a hook calls back Lua to execute a function or a chunk, this execution occurs without any calls to hooks.

lua_sethook

[-0, +0, -] 

int lua_sethook (lua_State *L, lua_Hook f, int mask, int count);

Sets the debugging hook function.

Argument f is the hook function. mask specifies on which events the hook will be called: it is formed by a bitwise or of the constants LUA_MASKCALL, LUA_MASKRET, LUA_MASKLINE, and LUA_MASKCOUNT. The count argument is only meaningful when the mask includes LUA_MASKCOUNT. For each event, the hook is called as explained below:

  • The call hook: is called when the interpreter calls a function. The hook is called just after Lua enters the new function, before the function gets its arguments.
  • The return hook: is called when the interpreter returns from a function. The hook is called just before Lua leaves the function. You have no access to the values to be returned by the function.
  • The line hook: is called when the interpreter is about to start the execution of a new line of code, or when it jumps back in the code (even to the same line). (This event only happens while Lua is executing a Lua function.)
  • The count hook: is called after the interpreter executes every count instructions. (This event only happens while Lua is executing a Lua function.)

A hook is disabled by setting mask to zero.

lua_setlocal

[-(0|1), +0, -] 

const char *lua_setlocal (lua_State *L, lua_Debug *ar, int n);

Sets the value of a local variable of a given activation record. Parameters ar and n are as in lua_getlocal (see lua_getlocal). lua_setlocal assigns the value at the top of the stack to the variable and returns its name. It also pops the value from the stack.

Returns NULL (and pops nothing) when the index is greater than the number of active local variables.

lua_setupvalue

[-(0|1), +0, -] 

const char *lua_setupvalue (lua_State *L, int funcindex, int n);

Sets the value of a closure's upvalue. It assigns the value at the top of the stack to the upvalue and returns its name. It also pops the value from the stack. Parameters funcindex and n are as in the lua_getupvalue (see lua_getupvalue).

Returns NULL (and pops nothing) when the index is greater than the number of upvalues.

4 - The Auxiliary Library

The auxiliary library provides several convenient functions to interface C with Lua. While the basic API provides the primitive functions for all interactions between C and Lua, the auxiliary library provides higher-level functions for some common tasks.

All functions from the auxiliary library are defined in header file lauxlib.h and have a prefix luaL_.

All functions in the auxiliary library are built on top of the basic API, and so they provide nothing that cannot be done with this API.

Several functions in the auxiliary library are used to check C function arguments. Their names are always luaL_check* or luaL_opt*. All of these functions throw an error if the check is not satisfied. Because the error message is formatted for arguments (e.g., "bad argument #1"), you should not use these functions for other stack values.

4.1 - Functions and Types

Here we list all functions and types from the auxiliary library in alphabetical order.

luaL_addchar

[-0, +0, m] 

void luaL_addchar (luaL_Buffer *B, char c);

Adds the character c to the buffer B (see luaL_Buffer).

luaL_addlstring

[-0, +0, m] 

void luaL_addlstring (luaL_Buffer *B, const char *s, size_t l);

Adds the string pointed to by s with length l to the buffer B (see luaL_Buffer). The string may contain embedded zeros.

luaL_addsize

[-0, +0, m] 

void luaL_addsize (luaL_Buffer *B, size_t n);

Adds to the buffer B (see luaL_Buffer) a string of length n previously copied to the buffer area (see luaL_prepbuffer).

luaL_addstring

[-0, +0, m] 

void luaL_addstring (luaL_Buffer *B, const char *s);

Adds the zero-terminated string pointed to by s to the buffer B (see luaL_Buffer). The string may not contain embedded zeros.

luaL_addvalue

[-1, +0, m] 

void luaL_addvalue (luaL_Buffer *B);

Adds the value at the top of the stack to the buffer B (see luaL_Buffer). Pops the value.

This is the only function on string buffers that can (and must) be called with an extra element on the stack, which is the value to be added to the buffer.

luaL_argcheck

[-0, +0, v] 

void luaL_argcheck (lua_State *L,
                    int cond,
                    int narg,
                    const char *extramsg);

Checks whether cond is true. If not, raises an error with the following message, where func is retrieved from the call stack: 

     bad argument #<narg> to <func> (<extramsg>)

luaL_argerror

[-0, +0, v] 

int luaL_argerror (lua_State *L, int narg, const char *extramsg);

Raises an error with the following message, where func is retrieved from the call stack: 

     bad argument #<narg> to <func> (<extramsg>)

This function never returns, but it is an idiom to use it in C functions as return luaL_argerror(args).

luaL_Buffer

typedef struct luaL_Buffer luaL_Buffer;

Type for a string buffer.

A string buffer allows C code to build Lua strings piecemeal. Its pattern of use is as follows:

  • First you declare a variable b of type luaL_Buffer.
  • Then you initialize it with a call luaL_buffinit(L, &b).
  • Then you add string pieces to the buffer calling any of the luaL_add* functions.
  • You finish by calling luaL_pushresult(&b). This call leaves the final string on the top of the stack.

During its normal operation, a string buffer uses a variable number of stack slots. So, while using a buffer, you cannot assume that you know where the top of the stack is. You can use the stack between successive calls to buffer operations as long as that use is balanced; that is, when you call a buffer operation, the stack is at the same level it was immediately after the previous buffer operation. (The only exception to this rule is luaL_addvalue.) After calling luaL_pushresult the stack is back to its level when the buffer was initialized, plus the final string on its top.

luaL_buffinit

[-0, +0, -] 

void luaL_buffinit (lua_State *L, luaL_Buffer *B);

Initializes a buffer B. This function does not allocate any space; the buffer must be declared as a variable (see luaL_Buffer).

luaL_callmeta

[-0, +(0|1), e] 

int luaL_callmeta (lua_State *L, int obj, const char *e);

Calls a metamethod.

If the object at index obj has a metatable and this metatable has a field e, this function calls this field and passes the object as its only argument. In this case this function returns 1 and pushes onto the stack the value returned by the call. If there is no metatable or no metamethod, this function returns 0 (without pushing any value on the stack).

luaL_checkany

[-0, +0, v] 

void luaL_checkany (lua_State *L, int narg);

Checks whether the function has an argument of any type (including nil) at position narg.

luaL_checkint

[-0, +0, v] 

int luaL_checkint (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to an int.

luaL_checkinteger

[-0, +0, v] 

lua_Integer luaL_checkinteger (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to a lua_Integer.

luaL_checklong

[-0, +0, v] 

long luaL_checklong (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to a long.

luaL_checklstring

[-0, +0, v] 

const char *luaL_checklstring (lua_State *L, int narg, size_t *l);

Checks whether the function argument narg is a string and returns this string; if l is not NULL fills *l with the string's length.

This function uses lua_tolstring to get its result, so all conversions and caveats of that function apply here.

luaL_checknumber

[-0, +0, v] 

lua_Number luaL_checknumber (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number.

luaL_checkoption

[-0, +0, v] 

int luaL_checkoption (lua_State *L,
                      int narg,
                      const char *def,
                      const char *const lst[]);

Checks whether the function argument narg is a string and searches for this string in the array lst (which must be NULL-terminated). Returns the index in the array where the string was found. Raises an error if the argument is not a string or if the string cannot be found.

If def is not NULL, the function uses def as a default value when there is no argument narg or if this argument is nil.

This is a useful function for mapping strings to C enums. (The usual convention in Lua libraries is to use strings instead of numbers to select options.)

luaL_checkstack

[-0, +0, v] 

void luaL_checkstack (lua_State *L, int sz, const char *msg);

Grows the stack size to top + sz elements, raising an error if the stack cannot grow to that size. msg is an additional text to go into the error message.

luaL_checkstring

[-0, +0, v] 

const char *luaL_checkstring (lua_State *L, int narg);

Checks whether the function argument narg is a string and returns this string.

This function uses lua_tolstring to get its result, so all conversions and caveats of that function apply here.

luaL_checktype

[-0, +0, v] 

void luaL_checktype (lua_State *L, int narg, int t);

Checks whether the function argument narg has type t. See lua_type for the encoding of types for t.

luaL_checkudata

[-0, +0, v] 

void *luaL_checkudata (lua_State *L, int narg, const char *tname);

Checks whether the function argument narg is a userdata of the type tname (see luaL_newmetatable).

luaL_dofile

[-0, +?, m] 

int luaL_dofile (lua_State *L, const char *filename);

Loads and runs the given file. It is defined as the following macro: 

     (luaL_loadfile(L, filename) || lua_pcall(L, 0, LUA_MULTRET, 0))

It returns 0 if there are no errors or 1 in case of errors.

luaL_dostring

[-0, +?, m] 

int luaL_dostring (lua_State *L, const char *str);

Loads and runs the given string. It is defined as the following macro: 

     (luaL_loadstring(L, str) || lua_pcall(L, 0, LUA_MULTRET, 0))

It returns 0 if there are no errors or 1 in case of errors.

luaL_error

[-0, +0, v] 

int luaL_error (lua_State *L, const char *fmt, ...);

Raises an error. The error message format is given by fmt plus any extra arguments, following the same rules of lua_pushfstring. It also adds at the beginning of the message the file name and the line number where the error occurred, if this information is available.

This function never returns, but it is an idiom to use it in C functions as return luaL_error(args).

luaL_getmetafield

[-0, +(0|1), m] 

int luaL_getmetafield (lua_State *L, int obj, const char *e);

Pushes onto the stack the field e from the metatable of the object at index obj. If the object does not have a metatable, or if the metatable does not have this field, returns 0 and pushes nothing.

luaL_getmetatable

[-0, +1, -] 

void luaL_getmetatable (lua_State *L, const char *tname);

Pushes onto the stack the metatable associated with name tname in the registry (see luaL_newmetatable).

luaL_gsub

[-0, +1, m] 

const char *luaL_gsub (lua_State *L,
                       const char *s,
                       const char *p,
                       const char *r);

Creates a copy of string s by replacing any occurrence of the string p with the string r. Pushes the resulting string on the stack and returns it.

luaL_loadbuffer

[-0, +1, m] 

int luaL_loadbuffer (lua_State *L,
                     const char *buff,
                     size_t sz,
                     const char *name);

Loads a buffer as a Lua chunk. This function uses lua_load to load the chunk in the buffer pointed to by buff with size sz.

This function returns the same results as lua_load. name is the chunk name, used for debug information and error messages.

luaL_loadfile

[-0, +1, m] 

int luaL_loadfile (lua_State *L, const char *filename);

Loads a file as a Lua chunk. This function uses lua_load to load the chunk in the file named filename. If filename is NULL, then it loads from the standard input. The first line in the file is ignored if it starts with a #.

This function returns the same results as lua_load, but it has an extra error code LUA_ERRFILE if it cannot open/read the file.

As lua_load, this function only loads the chunk; it does not run it.

luaL_loadstring

[-0, +1, m] 

int luaL_loadstring (lua_State *L, const char *s);

Loads a string as a Lua chunk. This function uses lua_load to load the chunk in the zero-terminated string s.

This function returns the same results as lua_load.

Also as lua_load, this function only loads the chunk; it does not run it.

luaL_newmetatable

[-0, +1, m] 

int luaL_newmetatable (lua_State *L, const char *tname);

If the registry already has the key tname, returns 0. Otherwise, creates a new table to be used as a metatable for userdata, adds it to the registry with key tname, and returns 1.

In both cases pushes onto the stack the final value associated with tname in the registry.

luaL_newstate

[-0, +0, -] 

lua_State *luaL_newstate (void);

Creates a new Lua state. It calls lua_newstate with an allocator based on the standard C realloc function and then sets a panic function (see lua_atpanic) that prints an error message to the standard error output in case of fatal errors.

Returns the new state, or NULL if there is a memory allocation error.

luaL_openlibs

[-0, +0, m] 

void luaL_openlibs (lua_State *L);

Opens all standard Lua libraries into the given state.

luaL_optint

[-0, +0, v] 

int luaL_optint (lua_State *L, int narg, int d);

If the function argument narg is a number, returns this number cast to an int. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optinteger

[-0, +0, v] 

lua_Integer luaL_optinteger (lua_State *L,
                             int narg,
                             lua_Integer d);

If the function argument narg is a number, returns this number cast to a lua_Integer. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optlong

[-0, +0, v] 

long luaL_optlong (lua_State *L, int narg, long d);

If the function argument narg is a number, returns this number cast to a long. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optlstring

[-0, +0, v] 

const char *luaL_optlstring (lua_State *L,
                             int narg,
                             const char *d,
                             size_t *l);

If the function argument narg is a string, returns this string. If this argument is absent or is nil, returns d. Otherwise, raises an error.

If l is not NULL, fills the position *l with the results's length.

luaL_optnumber

[-0, +0, v] 

lua_Number luaL_optnumber (lua_State *L, int narg, lua_Number d);

If the function argument narg is a number, returns this number. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optstring

[-0, +0, v] 

const char *luaL_optstring (lua_State *L,
                            int narg,
                            const char *d);

If the function argument narg is a string, returns this string. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_prepbuffer

[-0, +0, -] 

char *luaL_prepbuffer (luaL_Buffer *B);

Returns an address to a space of size LUAL_BUFFERSIZE where you can copy a string to be added to buffer B (see luaL_Buffer). After copying the string into this space you must call luaL_addsize with the size of the string to actually add it to the buffer.

luaL_pushresult

[-?, +1, m] 

void luaL_pushresult (luaL_Buffer *B);

Finishes the use of buffer B leaving the final string on the top of the stack.

luaL_ref

[-1, +0, m] 

int luaL_ref (lua_State *L, int t);

Creates and returns a reference, in the table at index t, for the object at the top of the stack (and pops the object).

A reference is a unique integer key. As long as you do not manually add integer keys into table t, luaL_ref ensures the uniqueness of the key it returns. You can retrieve an object referred by reference r by calling lua_rawgeti(L, t, r). Function luaL_unref frees a reference and its associated object.

If the object at the top of the stack is nil, luaL_ref returns the constant LUA_REFNIL. The constant LUA_NOREF is guaranteed to be different from any reference returned by luaL_ref.

luaL_Reg

typedef struct luaL_Reg {
  const char *name;
  lua_CFunction func;
} luaL_Reg;

Type for arrays of functions to be registered by luaL_register. name is the function name and func is a pointer to the function. Any array of luaL_Reg must end with an sentinel entry in which both name and func are NULL.

luaL_register

[-(0|1), +1, m] 

void luaL_register (lua_State *L,
                    const char *libname,
                    const luaL_Reg *l);

Opens a library.

When called with libname equal to NULL, it simply registers all functions in the list l (see luaL_Reg) into the table on the top of the stack.

When called with a non-null libname, luaL_register creates a new table t, sets it as the value of the global variable libname, sets it as the value of package.loaded[libname], and registers on it all functions in the list l. If there is a table in package.loaded[libname] or in variable libname, reuses this table instead of creating a new one.

In any case the function leaves the table on the top of the stack.

luaL_typename

[-0, +0, -] 

const char *luaL_typename (lua_State *L, int index);

Returns the name of the type of the value at the given index.

luaL_typerror

[-0, +0, v] 

int luaL_typerror (lua_State *L, int narg, const char *tname);

Generates an error with a message like the following: 

     location: bad argument narg to 'func' (tname expected, got rt)

where location is produced by luaL_where, func is the name of the current function, and rt is the type name of the actual argument.

luaL_unref

[-0, +0, -] 

void luaL_unref (lua_State *L, int t, int ref);

Releases reference ref from the table at index t (see luaL_ref). The entry is removed from the table, so that the referred object can be collected. The reference ref is also freed to be used again.

If ref is LUA_NOREF or LUA_REFNIL, luaL_unref does nothing.

luaL_where

[-0, +1, m] 

void luaL_where (lua_State *L, int lvl);

Pushes onto the stack a string identifying the current position of the control at level lvl in the call stack. Typically this string has the following format: 

     chunkname:currentline:

Level 0 is the running function, level 1 is the function that called the running function, etc.

This function is used to build a prefix for error messages.

5 - Standard Libraries

The standard Lua libraries provide useful functions that are implemented directly through the C API. Some of these functions provide essential services to the language (e.g., type and getmetatable); others provide access to "outside" services (e.g., I/O); and others could be implemented in Lua itself, but are quite useful or have critical performance requirements that deserve an implementation in C (e.g., table.sort).

All libraries are implemented through the official C API and are provided as separate C modules. Currently, Lua has the following standard libraries:

  • basic library, which includes the coroutine sub-library;
  • package library;
  • string manipulation;
  • table manipulation;
  • mathematical functions (sin, log, etc.);
  • input and output;
  • operating system facilities;
  • debug facilities.

Except for the basic and package libraries, each library provides all its functions as fields of a global table or as methods of its objects.

To have access to these libraries, the C host program should call the luaL_openlibs function, which opens all standard libraries. Alternatively, it can open them individually by calling luaopen_base (for the basic library), luaopen_package (for the package library), luaopen_string (for the string library), luaopen_table (for the table library), luaopen_math (for the mathematical library), luaopen_io (for the I/O library), luaopen_os (for the Operating System library), and luaopen_debug (for the debug library). These functions are declared in lualib.h and should not be called directly: you must call them like any other Lua C function, e.g., by using lua_call.

5.1 - Basic Functions

The basic library provides some core functions to Lua. If you do not include this library in your application, you should check carefully whether you need to provide implementations for some of its facilities.

assert (v [, message])

Issues an error when the value of its argument v is false (i.e., nil or false); otherwise, returns all its arguments. message is an error message; when absent, it defaults to "assertion failed!"

collectgarbage ([opt [, arg]])

This function is a generic interface to the garbage collector. It performs different functions according to its first argument, opt:

  • "collect": performs a full garbage-collection cycle. This is the default option.
  • "stop": stops the garbage collector.
  • "restart": restarts the garbage collector.
  • "count": returns the total memory in use by Lua (in Kbytes).
  • "step": performs a garbage-collection step. The step "size" is controlled by arg (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of arg. Returns true if the step finished a collection cycle.
  • "setpause": sets arg as the new value for the pause of the collector (see §2.10). Returns the previous value for pause.
  • "setstepmul": sets arg as the new value for the step multiplier of the collector (see §2.10). Returns the previous value for step.

dofile ([filename])

Opens the named file and executes its contents as a Lua chunk. When called without arguments, dofile executes the contents of the standard input (stdin). Returns all values returned by the chunk. In case of errors, dofile propagates the error to its caller (that is, dofile does not run in protected mode).

error (message [, level])

Terminates the last protected function called and returns message as the error message. Function error never returns.

Usually, error adds some information about the error position at the beginning of the message. The level argument specifies how to get the error position. With level 1 (the default), the error position is where the error function was called. Level 2 points the error to where the function that called error was called; and so on. Passing a level 0 avoids the addition of error position information to the message.

_G

A global variable (not a function) that holds the global environment (that is, _G._G = _G). Lua itself does not use this variable; changing its value does not affect any environment, nor vice-versa. (Use setfenv to change environments.)

getfenv ([f])

Returns the current environment in use by the function. f can be a Lua function or a number that specifies the function at that stack level: Level 1 is the function calling getfenv. If the given function is not a Lua function, or if f is 0, getfenv returns the global environment. The default for f is 1.

getmetatable (object)

If object does not have a metatable, returns nil. Otherwise, if the object's metatable has a "__metatable" field, returns the associated value. Otherwise, returns the metatable of the given object.

ipairs (t)

Returns three values: an iterator function, the table t, and 0, so that the construction 

     for i,v in ipairs(t) do body end

will iterate over the pairs (1,t[1]), (2,t[2]), ···, up to the first integer key absent from the table.

load (func [, chunkname])

Loads a chunk using function func to get its pieces. Each call to func must return a string that concatenates with previous results. A return of an empty string, nil, or no value signals the end of the chunk.

If there are no errors, returns the compiled chunk as a function; otherwise, returns nil plus the error message. The environment of the returned function is the global environment.

chunkname is used as the chunk name for error messages and debug information. When absent, it defaults to "=(load)".

loadfile ([filename])

Similar to load, but gets the chunk from file filename or from the standard input, if no file name is given.

loadstring (string [, chunkname])

Similar to load, but gets the chunk from the given string.

To load and run a given string, use the idiom 

     assert(loadstring(s))()

When absent, chunkname defaults to the given string.

next (table [, index])

Allows a program to traverse all fields of a table. Its first argument is a table and its second argument is an index in this table. next returns the next index of the table and its associated value. When called with nil as its second argument, next returns an initial index and its associated value. When called with the last index, or with nil in an empty table, next returns nil. If the second argument is absent, then it is interpreted as nil. In particular, you can use next(t) to check whether a table is empty.

The order in which the indices are enumerated is not specified, even for numeric indices. (To traverse a table in numeric order, use a numerical for or the ipairs function.)

The behavior of next is undefined if, during the traversal, you assign any value to a non-existent field in the table. You may however modify existing fields. In particular, you may clear existing fields.

pairs (t)

Returns three values: the next function, the table t, and nil, so that the construction 

     for k,v in pairs(t) do body end

will iterate over all key–value pairs of table t.

See function next for the caveats of modifying the table during its traversal.

pcall (f, arg1, ···)

Calls function f with the given arguments in protected mode. This means that any error inside f is not propagated; instead, pcall catches the error and returns a status code. Its first result is the status code (a boolean), which is true if the call succeeds without errors. In such case, pcall also returns all results from the call, after this first result. In case of any error, pcall returns false plus the error message.

print (···)

Receives any number of arguments, and prints their values to stdout, using the tostring function to convert them to strings. print is not intended for formatted output, but only as a quick way to show a value, typically for debugging. For formatted output, use string.format.

rawequal (v1, v2)

Checks whether v1 is equal to v2, without invoking any metamethod. Returns a boolean.

rawget (table, index)

Gets the real value of table[index], without invoking any metamethod. table must be a table; index may be any value.

rawset (table, index, value)

Sets the real value of table[index] to value, without invoking any metamethod. table must be a table, index any value different from nil, and value any Lua value.

This function returns table.

select (index, ···)

If index is a number, returns all arguments after argument number index. Otherwise, index must be the string "#", and select returns the total number of extra arguments it received.

setfenv (f, table)

Sets the environment to be used by the given function. f can be a Lua function or a number that specifies the function at that stack level: Level 1 is the function calling setfenv. setfenv returns the given function.

As a special case, when f is 0 setfenv changes the environment of the running thread. In this case, setfenv returns no values.

setmetatable (table, metatable)

Sets the metatable for the given table. (You cannot change the metatable of other types from Lua, only from C.) If metatable is nil, removes the metatable of the given table. If the original metatable has a "__metatable" field, raises an error.

This function returns table.

tonumber (e [, base])

Tries to convert its argument to a number. If the argument is already a number or a string convertible to a number, then tonumber returns this number; otherwise, it returns nil.

An optional argument specifies the base to interpret the numeral. The base may be any integer between 2 and 36, inclusive. In bases above 10, the letter 'A' (in either upper or lower case) represents 10, 'B' represents 11, and so forth, with 'Z' representing 35. In base 10 (the default), the number can have a decimal part, as well as an optional exponent part (see §2.1). In other bases, only unsigned integers are accepted.

tostring (e)

Receives an argument of any type and converts it to a string in a reasonable format. For complete control of how numbers are converted, use string.format.

If the metatable of e has a "__tostring" field, then tostring calls the corresponding value with e as argument, and uses the result of the call as its result.

type (v)

Returns the type of its only argument, coded as a string. The possible results of this function are "nil" (a string, not the value nil), "number", "string", "boolean", "table", "function", "thread", and "userdata".

unpack (list [, i [, j]])

Returns the elements from the given table. This function is equivalent to 
     return list[i], list[i+1], ···, list[j]

except that the above code can be written only for a fixed number of elements. By default, i is 1 and j is the length of the list, as defined by the length operator (see §2.5.5).

_VERSION

A global variable (not a function) that holds a string containing the current interpreter version. The current contents of this variable is "Lua 5.1".

xpcall (f, err)

This function is similar to pcall, except that you can set a new error handler.

xpcall calls function f in protected mode, using err as the error handler. Any error inside f is not propagated; instead, xpcall catches the error, calls the err function with the original error object, and returns a status code. Its first result is the status code (a boolean), which is true if the call succeeds without errors. In this case, xpcall also returns all results from the call, after this first result. In case of any error, xpcall returns false plus the result from err.

5.2 - Coroutine Manipulation

The operations related to coroutines comprise a sub-library of the basic library and come inside the table coroutine. See §2.11 for a general description of coroutines.

coroutine.create (f)

Creates a new coroutine, with body f. f must be a Lua function. Returns this new coroutine, an object with type "thread".

coroutine.resume (co [, val1, ···])

Starts or continues the execution of coroutine co. The first time you resume a coroutine, it starts running its body. The values val1, ··· are passed as the arguments to the body function. If the coroutine has yielded, resume restarts it; the values val1, ··· are passed as the results from the yield.

If the coroutine runs without any errors, resume returns true plus any values passed to yield (if the coroutine yields) or any values returned by the body function (if the coroutine terminates). If there is any error, resume returns false plus the error message.

coroutine.running ()

Returns the running coroutine, or nil when called by the main thread.

coroutine.status (co)

Returns the status of coroutine co, as a string: "running", if the coroutine is running (that is, it called status); "suspended", if the coroutine is suspended in a call to yield, or if it has not started running yet; "normal" if the coroutine is active but not running (that is, it has resumed another coroutine); and "dead" if the coroutine has finished its body function, or if it has stopped with an error.

coroutine.wrap (f)

Creates a new coroutine, with body f. f must be a Lua function. Returns a function that resumes the coroutine each time it is called. Any arguments passed to the function behave as the extra arguments to resume. Returns the same values returned by resume, except the first boolean. In case of error, propagates the error.

coroutine.yield (···)

Suspends the execution of the calling coroutine. The coroutine cannot be running a C function, a metamethod, or an iterator. Any arguments to yield are passed as extra results to resume.

5.3 - Modules

The package library provides basic facilities for loading and building modules in Lua. It exports two of its functions directly in the global environment: require and module. Everything else is exported in a table package.

module (name [, ···])

Creates a module. If there is a table in package.loaded[name], this table is the module. Otherwise, if there is a global table t with the given name, this table is the module. Otherwise creates a new table t and sets it as the value of the global name and the value of package.loaded[name]. This function also initializes t._NAME with the given name, t._M with the module (t itself), and t._PACKAGE with the package name (the full module name minus last component; see below). Finally, module sets t as the new environment of the current function and the new value of package.loaded[name], so that require returns t.

If name is a compound name (that is, one with components separated by dots), module creates (or reuses, if they already exist) tables for each component. For instance, if name is a.b.c, then module stores the module table in field c of field b of global a.

This function can receive optional options after the module name, where each option is a function to be applied over the module.

require (modname)

Loads the given module. The function starts by looking into the package.loaded table to determine whether modname is already loaded. If it is, then require returns the value stored at package.loaded[modname]. Otherwise, it tries to find a loader for the module.

To find a loader, require is guided by the package.loaders array. By changing this array, we can change how require looks for a module. The following explanation is based on the default configuration for package.loaders.

First require queries package.preload[modname]. If it has a value, this value (which should be a function) is the loader. Otherwise require searches for a Lua loader using the path stored in package.path. If that also fails, it searches for a C loader using the path stored in package.cpath. If that also fails, it tries an all-in-one loader (see package.loaders).

Once a loader is found, require calls the loader with a single argument, modname. If the loader returns any value, require assigns the returned value to package.loaded[modname]. If the loader returns no value and has not assigned any value to package.loaded[modname], then require assigns true to this entry. In any case, require returns the final value of package.loaded[modname].

If there is any error loading or running the module, or if it cannot find any loader for the module, then require signals an error.

package.cpath

The path used by require to search for a C loader.

Lua initializes the C path package.cpath in the same way it initializes the Lua path package.path, using the environment variable LUA_CPATH or a default path defined in luaconf.h.

package.loaded

A table used by require to control which modules are already loaded. When you require a module modname and package.loaded[modname] is not false, require simply returns the value stored there.

package.loaders

A table used by require to control how to load modules.

Each entry in this table is a searcher function. When looking for a module, require calls each of these searchers in ascending order, with the module name (the argument given to require) as its sole parameter. The function can return another function (the module loader) or a string explaining why it did not find that module (or nil if it has nothing to say). Lua initializes this table with four functions.

The first searcher simply looks for a loader in the package.preload table.

The second searcher looks for a loader as a Lua library, using the path stored at package.path. A path is a sequence of templates separated by semicolons. For each template, the searcher will change each interrogation mark in the template by filename, which is the module name with each dot replaced by a "directory separator" (such as "/" in Unix); then it will try to open the resulting file name. So, for instance, if the Lua path is the string 

     "./?.lua;./?.lc;/usr/local/?/init.lua"

the search for a Lua file for module foo will try to open the files ./foo.lua, ./foo.lc, and /usr/local/foo/init.lua, in that order.

The third searcher looks for a loader as a C library, using the path given by the variable package.cpath. For instance, if the C path is the string 

     "./?.so;./?.dll;/usr/local/?/init.so"

the searcher for module foo will try to open the files ./foo.so, ./foo.dll, and /usr/local/foo/init.so, in that order. Once it finds a C library, this searcher first uses a dynamic link facility to link the application with the library. Then it tries to find a C function inside the library to be used as the loader. The name of this C function is the string "luaopen_" concatenated with a copy of the module name where each dot is replaced by an underscore. Moreover, if the module name has a hyphen, its prefix up to (and including) the first hyphen is removed. For instance, if the module name is a.v1-b.c, the function name will be luaopen_b_c.

The fourth searcher tries an all-in-one loader. It searches the C path for a library for the root name of the given module. For instance, when requiring a.b.c, it will search for a C library for a. If found, it looks into it for an open function for the submodule; in our example, that would be luaopen_a_b_c. With this facility, a package can pack several C submodules into one single library, with each submodule keeping its original open function.

package.loadlib (libname, funcname)

Dynamically links the host program with the C library libname. Inside this library, looks for a function funcname and returns this function as a C function. (So, funcname must follow the protocol (see lua_CFunction)).

This is a low-level function. It completely bypasses the package and module system. Unlike require, it does not perform any path searching and does not automatically adds extensions. libname must be the complete file name of the C library, including if necessary a path and extension. funcname must be the exact name exported by the C library (which may depend on the C compiler and linker used).

This function is not supported by ANSI C. As such, it is only available on some platforms (Windows, Linux, Mac OS X, Solaris, BSD, plus other Unix systems that support the dlfcn standard).

package.path

The path used by require to search for a Lua loader.

At start-up, Lua initializes this variable with the value of the environment variable LUA_PATH or with a default path defined in luaconf.h, if the environment variable is not defined. Any ";;" in the value of the environment variable is replaced by the default path.

package.preload

A table to store loaders for specific modules (see require).

package.seeall (module)

Sets a metatable for module with its __index field referring to the global environment, so that this module inherits values from the global environment. To be used as an option to function module.

5.4 - String Manipulation

This library provides generic functions for string manipulation, such as finding and extracting substrings, and pattern matching. When indexing a string in Lua, the first character is at position 1 (not at 0, as in C). Indices are allowed to be negative and are interpreted as indexing backwards, from the end of the string. Thus, the last character is at position -1, and so on.

The string library provides all its functions inside the table string. It also sets a metatable for strings where the __index field points to the string table. Therefore, you can use the string functions in object-oriented style. For instance, string.byte(s, i) can be written as s:byte(i).

The string library assumes one-byte character encodings.

string.byte (s [, i [, j]])

Returns the internal numerical codes of the characters s[i], s[i+1], ···, s[j]. The default value for i is 1; the default value for j is i.

Note that numerical codes are not necessarily portable across platforms.

string.char (···)

Receives zero or more integers. Returns a string with length equal to the number of arguments, in which each character has the internal numerical code equal to its corresponding argument.

Note that numerical codes are not necessarily portable across platforms.

string.dump (function)

Returns a string containing a binary representation of the given function, so that a later loadstring on this string returns a copy of the function. function must be a Lua function without upvalues.

string.find (s, pattern [, init [, plain]])

Looks for the first match of pattern in the string s. If it finds a match, then find returns the indices of s where this occurrence starts and ends; otherwise, it returns nil. A third, optional numerical argument init specifies where to start the search; its default value is 1 and can be negative. A value of true as a fourth, optional argument plain turns off the pattern matching facilities, so the function does a plain "find substring" operation, with no characters in pattern being considered "magic". Note that if plain is given, then init must be given as well.

If the pattern has captures, then in a successful match the captured values are also returned, after the two indices.

string.format (formatstring, ···)

Returns a formatted version of its variable number of arguments following the description given in its first argument (which must be a string). The format string follows the same rules as the printf family of standard C functions. The only differences are that the options/modifiers *, l, L, n, p, and h are not supported and that there is an extra option, q. The q option formats a string in a form suitable to be safely read back by the Lua interpreter: the string is written between double quotes, and all double quotes, newlines, embedded zeros, and backslashes in the string are correctly escaped when written. For instance, the call 
     string.format('%q', 'a string with "quotes" and \n new line')

will produce the string: 

     "a string with \"quotes\" and \
      new line"

The options c, d, E, e, f, g, G, i, o, u, X, and x all expect a number as argument, whereas q and s expect a string.

This function does not accept string values containing embedded zeros, except as arguments to the q option.

string.gmatch (s, pattern)

Returns an iterator function that, each time it is called, returns the next captures from pattern over string s. If pattern specifies no captures, then the whole match is produced in each call.

As an example, the following loop 

     s = "hello world from Lua"
     for w in string.gmatch(s, "%a+") do
       print(w)
     end

will iterate over all the words from string s, printing one per line. The next example collects all pairs key=value from the given string into a table: 

     t = {}
     s = "from=world, to=Lua"
     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
       t[k] = v
     end

For this function, a '^' at the start of a pattern does not work as an anchor, as this would prevent the iteration.

string.gsub (s, pattern, repl [, n])

Returns a copy of s in which all (or the first n, if given) occurrences of the pattern have been replaced by a replacement string specified by repl, which can be a string, a table, or a function. gsub also returns, as its second value, the total number of matches that occurred.

If repl is a string, then its value is used for replacement. The character % works as an escape character: any sequence in repl of the form %n, with n between 1 and 9, stands for the value of the n-th captured substring (see below). The sequence %0 stands for the whole match. The sequence %% stands for a single %.

If repl is a table, then the table is queried for every match, using the first capture as the key; if the pattern specifies no captures, then the whole match is used as the key.

If repl is a function, then this function is called every time a match occurs, with all captured substrings passed as arguments, in order; if the pattern specifies no captures, then the whole match is passed as a sole argument.

If the value returned by the table query or by the function call is a string or a number, then it is used as the replacement string; otherwise, if it is false or nil, then there is no replacement (that is, the original match is kept in the string).

Here are some examples: 

     x = string.gsub("hello world", "(%w+)", "%1 %1")
     --> x="hello hello world world"
     
     x = string.gsub("hello world", "%w+", "%0 %0", 1)
     --> x="hello hello world"
     
     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
     --> x="world hello Lua from"
     
     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
     --> x="home = /home/roberto, user = roberto"
     
     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
           return loadstring(s)()
         end)
     --> x="4+5 = 9"
     
     local t = {name="lua", version="5.1"}
     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
     --> x="lua-5.1.tar.gz"

string.len (s)

Receives a string and returns its length. The empty string "" has length 0. Embedded zeros are counted, so "a\000bc\000" has length 5.

string.lower (s)

Receives a string and returns a copy of this string with all uppercase letters changed to lowercase. All other characters are left unchanged. The definition of what an uppercase letter is depends on the current locale.

string.match (s, pattern [, init])

Looks for the first match of pattern in the string s. If it finds one, then match returns the captures from the pattern; otherwise it returns nil. If pattern specifies no captures, then the whole match is returned. A third, optional numerical argument init specifies where to start the search; its default value is 1 and can be negative.

string.rep (s, n)

Returns a string that is the concatenation of n copies of the string s.

string.reverse (s)

Returns a string that is the string s reversed.

string.sub (s, i [, j])

Returns the substring of s that starts at i and continues until j; i and j can be negative. If j is absent, then it is assumed to be equal to -1 (which is the same as the string length). In particular, the call string.sub(s,1,j) returns a prefix of s with length j, and string.sub(s, -i) returns a suffix of s with length i.

string.upper (s)

Receives a string and returns a copy of this string with all lowercase letters changed to uppercase. All other characters are left unchanged. The definition of what a lowercase letter is depends on the current locale.

5.4.1 - Patterns

Character Class:

A character class is used to represent a set of characters. The following combinations are allowed in describing a character class:

  • x: (where x is not one of the magic characters ^$()%.[]*+-?) represents the character x itself.
  • .: (a dot) represents all characters.
  • %a: represents all letters.
  • %c: represents all control characters.
  • %d: represents all digits.
  • %l: represents all lowercase letters.
  • %p: represents all punctuation characters.
  • %s: represents all space characters.
  • %u: represents all uppercase letters.
  • %w: represents all alphanumeric characters.
  • %x: represents all hexadecimal digits.
  • %z: represents the character with representation 0.
  • %x: (where x is any non-alphanumeric character) represents the character x. This is the standard way to escape the magic characters. Any punctuation character (even the non magic) can be preceded by a '%' when used to represent itself in a pattern.
  • [set]: represents the class which is the union of all characters in set. A range of characters can be specified by separating the end characters of the range with a '-'. All classes %x described above can also be used as components in set. All other characters in set represent themselves. For example, [%w_] (or [_%w]) represents all alphanumeric characters plus the underscore, [0-7] represents the octal digits, and [0-7%l%-] represents the octal digits plus the lowercase letters plus the '-' character.

    The interaction between ranges and classes is not defined. Therefore, patterns like [%a-z] or [a-%%] have no meaning.

  • [^set]: represents the complement of set, where set is interpreted as above.

For all classes represented by single letters (%a, %c, etc.), the corresponding uppercase letter represents the complement of the class. For instance, %S represents all non-space characters.

The definitions of letter, space, and other character groups depend on the current locale. In particular, the class [a-z] may not be equivalent to %l.

Pattern Item:

A pattern item can be

  • a single character class, which matches any single character in the class;
  • a single character class followed by '*', which matches 0 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence;
  • a single character class followed by '+', which matches 1 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence;
  • a single character class followed by '-', which also matches 0 or more repetitions of characters in the class. Unlike '*', these repetition items will always match the shortest possible sequence;
  • a single character class followed by '?', which matches 0 or 1 occurrence of a character in the class;
  • %n, for n between 1 and 9; such item matches a substring equal to the n-th captured string (see below);
  • %bxy, where x and y are two distinct characters; such item matches strings that start with x, end with y, and where the x and y are balanced. This means that, if one reads the string from left to right, counting +1 for an x and -1 for a y, the ending y is the first y where the count reaches 0. For instance, the item %b() matches expressions with balanced parentheses.

Pattern:

A pattern is a sequence of pattern items. A '^' at the beginning of a pattern anchors the match at the beginning of the subject string. A '$' at the end of a pattern anchors the match at the end of the subject string. At other positions, '^' and '$' have no special meaning and represent themselves.

Captures:

A pattern can contain sub-patterns enclosed in parentheses; they describe captures. When a match succeeds, the substrings of the subject string that match captures are stored (captured) for future use. Captures are numbered according to their left parentheses. For instance, in the pattern "(a*(.)%w(%s*))", the part of the string matching "a*(.)%w(%s*)" is stored as the first capture (and therefore has number 1); the character matching "." is captured with number 2, and the part matching "%s*" has number 3.

As a special case, the empty capture () captures the current string position (a number). For instance, if we apply the pattern "()aa()" on the string "flaaap", there will be two captures: 3 and 5.

A pattern cannot contain embedded zeros. Use %z instead.

5.5 - Table Manipulation

This library provides generic functions for table manipulation. It provides all its functions inside the table table.

Most functions in the table library assume that the table represents an array or a list. For these functions, when we talk about the "length" of a table we mean the result of the length operator.

table.concat (table [, sep [, i [, j]]])

Given an array where all elements are strings or numbers, returns table[i]..sep..table[i+1] ··· sep..table[j]. The default value for sep is the empty string, the default for i is 1, and the default for j is the length of the table. If i is greater than j, returns the empty string.

table.insert (table, [pos,] value)

Inserts element value at position pos in table, shifting up other elements to open space, if necessary. The default value for pos is n+1, where n is the length of the table (see §2.5.5), so that a call table.insert(t,x) inserts x at the end of table t.

table.maxn (table)

Returns the largest positive numerical index of the given table, or zero if the table has no positive numerical indices. (To do its job this function does a linear traversal of the whole table.)

table.remove (table [, pos])

Removes from table the element at position pos, shifting down other elements to close the space, if necessary. Returns the value of the removed element. The default value for pos is n, where n is the length of the table, so that a call table.remove(t) removes the last element of table t.

table.sort (table [, comp])

Sorts table elements in a given order, in-place, from table[1] to table[n], where n is the length of the table. If comp is given, then it must be a function that receives two table elements, and returns true when the first is less than the second (so that not comp(a[i+1],a[i]) will be true after the sort). If comp is not given, then the standard Lua operator < is used instead.

The sort algorithm is not stable; that is, elements considered equal by the given order may have their relative positions changed by the sort.

5.6 - Mathematical Functions

This library is an interface to the standard C math library. It provides all its functions inside the table math.

math.abs (x)

Returns the absolute value of x.

math.acos (x)

Returns the arc cosine of x (in radians).

math.asin (x)

Returns the arc sine of x (in radians).

math.atan (x)

Returns the arc tangent of x (in radians).

math.atan2 (y, x)

Returns the arc tangent of y/x (in radians), but uses the signs of both parameters to find the quadrant of the result. (It also handles correctly the case of x being zero.)

math.ceil (x)

Returns the smallest integer larger than or equal to x.

math.cos (x)

Returns the cosine of x (assumed to be in radians).

math.cosh (x)

Returns the hyperbolic cosine of x.

math.deg (x)

Returns the angle x (given in radians) in degrees.

math.exp (x)

Returns the value ex.

math.floor (x)

Returns the largest integer smaller than or equal to x.

math.fmod (x, y)

Returns the remainder of the division of x by y that rounds the quotient towards zero.

math.frexp (x)

Returns m and e such that x = m2e, e is an integer and the absolute value of m is in the range [0.5, 1) (or zero when x is zero).

math.huge

The value HUGE_VAL, a value larger than or equal to any other numerical value.

math.ldexp (m, e)

Returns m2e (e should be an integer).

math.log (x)

Returns the natural logarithm of x.

math.log10 (x)

Returns the base-10 logarithm of x.

math.max (x, ···)

Returns the maximum value among its arguments.

math.min (x, ···)

Returns the minimum value among its arguments.

math.modf (x)

Returns two numbers, the integral part of x and the fractional part of x.

math.pi

The value of pi.

math.pow (x, y)

Returns xy. (You can also use the expression x^y to compute this value.)

math.rad (x)

Returns the angle x (given in degrees) in radians.

math.random ([m [, n]])

This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. (No guarantees can be given for its statistical properties.)

When called without arguments, returns a uniform pseudo-random real number in the range [0,1). When called with an integer number m, math.random returns a uniform pseudo-random integer in the range [1, m]. When called with two integer numbers m and n, math.random returns a uniform pseudo-random integer in the range [m, n].

math.randomseed (x)

Sets x as the "seed" for the pseudo-random generator: equal seeds produce equal sequences of numbers.

math.sin (x)

Returns the sine of x (assumed to be in radians).

math.sinh (x)

Returns the hyperbolic sine of x.

math.sqrt (x)

Returns the square root of x. (You can also use the expression x^0.5 to compute this value.)

math.tan (x)

Returns the tangent of x (assumed to be in radians).

math.tanh (x)

Returns the hyperbolic tangent of x.

5.7 - Input and Output Facilities

The I/O library provides two different styles for file manipulation. The first one uses implicit file descriptors; that is, there are operations to set a default input file and a default output file, and all input/output operations are over these default files. The second style uses explicit file descriptors.

When using implicit file descriptors, all operations are supplied by table io. When using explicit file descriptors, the operation io.open returns a file descriptor and then all operations are supplied as methods of the file descriptor.

The table io also provides three predefined file descriptors with their usual meanings from C: io.stdin, io.stdout, and io.stderr. The I/O library never closes these files.

Unless otherwise stated, all I/O functions return nil on failure (plus an error message as a second result and a system-dependent error code as a third result) and some value different from nil on success.

io.close ([file])

Equivalent to file:close(). Without a file, closes the default output file.

io.flush ()

Equivalent to file:flush over the default output file.

io.input ([file])

When called with a file name, it opens the named file (in text mode), and sets its handle as the default input file. When called with a file handle, it simply sets this file handle as the default input file. When called without parameters, it returns the current default input file.

In case of errors this function raises the error, instead of returning an error code.

io.lines ([filename])

Opens the given file name in read mode and returns an iterator function that, each time it is called, returns a new line from the file. Therefore, the construction 

     for line in io.lines(filename) do body end

will iterate over all lines of the file. When the iterator function detects the end of file, it returns nil (to finish the loop) and automatically closes the file.

The call io.lines() (with no file name) is equivalent to io.input():lines(); that is, it iterates over the lines of the default input file. In this case it does not close the file when the loop ends.

io.open (filename [, mode])

This function opens a file, in the mode specified in the string mode. It returns a new file handle, or, in case of errors, nil plus an error message.

The mode string can be any of the following:

  • "r": read mode (the default);
  • "w": write mode;
  • "a": append mode;
  • "r+": update mode, all previous data is preserved;
  • "w+": update mode, all previous data is erased;
  • "a+": append update mode, previous data is preserved, writing is only allowed at the end of file.

The mode string can also have a 'b' at the end, which is needed in some systems to open the file in binary mode. This string is exactly what is used in the standard C function fopen.

io.output ([file])

Similar to io.input, but operates over the default output file.

io.popen (prog [, mode])

Starts program prog in a separated process and returns a file handle that you can use to read data from this program (if mode is "r", the default) or to write data to this program (if mode is "w").

This function is system dependent and is not available on all platforms.

io.read (···)

Equivalent to io.input():read.

io.tmpfile ()

Returns a handle for a temporary file. This file is opened in update mode and it is automatically removed when the program ends.

io.type (obj)

Checks whether obj is a valid file handle. Returns the string "file" if obj is an open file handle, "closed file" if obj is a closed file handle, or nil if obj is not a file handle.

io.write (···)

Equivalent to io.output():write.

file:close ()

Closes file. Note that files are automatically closed when their handles are garbage collected, but that takes an unpredictable amount of time to happen.

file:flush ()

Saves any written data to file.

file:lines ()

Returns an iterator function that, each time it is called, returns a new line from the file. Therefore, the construction 

     for line in file:lines() do body end

will iterate over all lines of the file. (Unlike io.lines, this function does not close the file when the loop ends.)

file:read (···)

Reads the file file, according to the given formats, which specify what to read. For each format, the function returns a string (or a number) with the characters read, or nil if it cannot read data with the specified format. When called without formats, it uses a default format that reads the entire next line (see below).

The available formats are

  • "*n": reads a number; this is the only format that returns a number instead of a string.
  • "*a": reads the whole file, starting at the current position. On end of file, it returns the empty string.
  • "*l": reads the next line (skipping the end of line), returning nil on end of file. This is the default format.
  • number: reads a string with up to this number of characters, returning nil on end of file. If number is zero, it reads nothing and returns an empty string, or nil on end of file.

file:seek ([whence] [, offset])

Sets and gets the file position, measured from the beginning of the file, to the position given by offset plus a base specified by the string whence, as follows:

  • "set": base is position 0 (beginning of the file);
  • "cur": base is current position;
  • "end": base is end of file;

In case of success, function seek returns the final file position, measured in bytes from the beginning of the file. If this function fails, it returns nil, plus a string describing the error.

The default value for whence is "cur", and for offset is 0. Therefore, the call file:seek() returns the current file position, without changing it; the call file:seek("set") sets the position to the beginning of the file (and returns 0); and the call file:seek("end") sets the position to the end of the file, and returns its size.

file:setvbuf (mode [, size])

Sets the buffering mode for an output file. There are three available modes:

  • "no": no buffering; the result of any output operation appears immediately.
  • "full": full buffering; output operation is performed only when the buffer is full (or when you explicitly flush the file (see io.flush)).
  • "line": line buffering; output is buffered until a newline is output or there is any input from some special files (such as a terminal device).

For the last two cases, size specifies the size of the buffer, in bytes. The default is an appropriate size.

file:write (···)

Writes the value of each of its arguments to the file. The arguments must be strings or numbers. To write other values, use tostring or string.format before write.

5.8 - Operating System Facilities

This library is implemented through table os.

os.clock ()

Returns an approximation of the amount in seconds of CPU time used by the program.

os.date ([format [, time]])

Returns a string or a table containing date and time, formatted according to the given string format.

If the time argument is present, this is the time to be formatted (see the os.time function for a description of this value). Otherwise, date formats the current time.

If format starts with '!', then the date is formatted in Coordinated Universal Time. After this optional character, if format is the string "*t", then date returns a table with the following fields: year (four digits), month (1--12), day (1--31), hour (0--23), min (0--59), sec (0--61), wday (weekday, Sunday is 1), yday (day of the year), and isdst (daylight saving flag, a boolean).

If format is not "*t", then date returns the date as a string, formatted according to the same rules as the C function strftime.

When called without arguments, date returns a reasonable date and time representation that depends on the host system and on the current locale (that is, os.date() is equivalent to os.date("%c")).

os.difftime (t2, t1)

Returns the number of seconds from time t1 to time t2. In POSIX, Windows, and some other systems, this value is exactly t2-t1.

os.execute ([command])

This function is equivalent to the C function system. It passes command to be executed by an operating system shell. It returns a status code, which is system-dependent. If command is absent, then it returns nonzero if a shell is available and zero otherwise.

os.exit ([code])

Calls the C function exit, with an optional code, to terminate the host program. The default value for code is the success code.

os.getenv (varname)

Returns the value of the process environment variable varname, or nil if the variable is not defined.

os.remove (filename)

Deletes the file or directory with the given name. Directories must be empty to be removed. If this function fails, it returns nil, plus a string describing the error.

os.rename (oldname, newname)

Renames file or directory named oldname to newname. If this function fails, it returns nil, plus a string describing the error.

os.setlocale (locale [, category])

Sets the current locale of the program. locale is a string specifying a locale; category is an optional string describing which category to change: "all", "collate", "ctype", "monetary", "numeric", or "time"; the default category is "all". The function returns the name of the new locale, or nil if the request cannot be honored.

If locale is the empty string, the current locale is set to an implementation-defined native locale. If locale is the string "C", the current locale is set to the standard C locale.

When called with nil as the first argument, this function only returns the name of the current locale for the given category.

os.time ([table])

Returns the current time when called without arguments, or a time representing the date and time specified by the given table. This table must have fields year, month, and day, and may have fields hour, min, sec, and isdst (for a description of these fields, see the os.date function).

The returned value is a number, whose meaning depends on your system. In POSIX, Windows, and some other systems, this number counts the number of seconds since some given start time (the "epoch"). In other systems, the meaning is not specified, and the number returned by time can be used only as an argument to date and difftime.

os.tmpname ()

Returns a string with a file name that can be used for a temporary file. The file must be explicitly opened before its use and explicitly removed when no longer needed.

On some systems (POSIX), this function also creates a file with that name, to avoid security risks. (Someone else might create the file with wrong permissions in the time between getting the name and creating the file.) You still have to open the file to use it and to remove it (even if you do not use it).

When possible, you may prefer to use io.tmpfile, which automatically removes the file when the program ends.

5.9 - The Debug Library

This library provides the functionality of the debug interface to Lua programs. You should exert care when using this library. The functions provided here should be used exclusively for debugging and similar tasks, such as profiling. Please resist the temptation to use them as a usual programming tool: they can be very slow. Moreover, several of these functions violate some assumptions about Lua code (e.g., that variables local to a function cannot be accessed from outside or that userdata metatables cannot be changed by Lua code) and therefore can compromise otherwise secure code.

All functions in this library are provided inside the debug table. All functions that operate over a thread have an optional first argument which is the thread to operate over. The default is always the current thread.

debug.debug ()

Enters an interactive mode with the user, running each string that the user enters. Using simple commands and other debug facilities, the user can inspect global and local variables, change their values, evaluate expressions, and so on. A line containing only the word cont finishes this function, so that the caller continues its execution.

Note that commands for debug.debug are not lexically nested within any function, and so have no direct access to local variables.

debug.getfenv (o)

Returns the environment of object o.

debug.gethook ([thread])

Returns the current hook settings of the thread, as three values: the current hook function, the current hook mask, and the current hook count (as set by the debug.sethook function).

debug.getinfo ([thread,] function [, what])

Returns a table with information about a function. You can give the function directly, or you can give a number as the value of function, which means the function running at level function of the call stack of the given thread: level 0 is the current function (getinfo itself); level 1 is the function that called getinfo; and so on. If function is a number larger than the number of active functions, then getinfo returns nil.

The returned table can contain all the fields returned by lua_getinfo, with the string what describing which fields to fill in. The default for what is to get all information available, except the table of valid lines. If present, the option 'f' adds a field named func with the function itself. If present, the option 'L' adds a field named activelines with the table of valid lines.

For instance, the expression debug.getinfo(1,"n").name returns a table with a name for the current function, if a reasonable name can be found, and the expression debug.getinfo(print) returns a table with all available information about the print function.

debug.getlocal ([thread,] level, local)

This function returns the name and the value of the local variable with index local of the function at level level of the stack. (The first parameter or local variable has index 1, and so on, until the last active local variable.) The function returns nil if there is no local variable with the given index, and raises an error when called with a level out of range. (You can call debug.getinfo to check whether the level is valid.)

Variable names starting with '(' (open parentheses) represent internal variables (loop control variables, temporaries, and C function locals).

debug.getmetatable (object)

Returns the metatable of the given object or nil if it does not have a metatable.

debug.getregistry ()

Returns the registry table (see §3.5).

debug.getupvalue (func, up)

This function returns the name and the value of the upvalue with index up of the function func. The function returns nil if there is no upvalue with the given index.

debug.setfenv (object, table)

Sets the environment of the given object to the given table. Returns object.

debug.sethook ([thread,] hook, mask [, count])

Sets the given function as a hook. The string mask and the number count describe when the hook will be called. The string mask may have the following characters, with the given meaning:

  • "c": the hook is called every time Lua calls a function;
  • "r": the hook is called every time Lua returns from a function;
  • "l": the hook is called every time Lua enters a new line of code.

With a count different from zero, the hook is called after every count instructions.

When called without arguments, debug.sethook turns off the hook.

When the hook is called, its first parameter is a string describing the event that has triggered its call: "call", "return" (or "tail return", when simulating a return from a tail call), "line", and "count". For line events, the hook also gets the new line number as its second parameter. Inside a hook, you can call getinfo with level 2 to get more information about the running function (level 0 is the getinfo function, and level 1 is the hook function), unless the event is "tail return". In this case, Lua is only simulating the return, and a call to getinfo will return invalid data.

debug.setlocal ([thread,] level, local, value)

This function assigns the value value to the local variable with index local of the function at level level of the stack. The function returns nil if there is no local variable with the given index, and raises an error when called with a level out of range. (You can call getinfo to check whether the level is valid.) Otherwise, it returns the name of the local variable.

debug.setmetatable (object, table)

Sets the metatable for the given object to the given table (which can be nil).

debug.setupvalue (func, up, value)

This function assigns the value value to the upvalue with index up of the function func. The function returns nil if there is no upvalue with the given index. Otherwise, it returns the name of the upvalue.

debug.traceback ([thread,] [message [, level]])

Returns a string with a traceback of the call stack. An optional message string is appended at the beginning of the traceback. An optional level number tells at which level to start the traceback (default is 1, the function calling traceback).

6 - Lua Stand-alone

Although Lua has been designed as an extension language, to be embedded in a host C program, it is also frequently used as a stand-alone language. An interpreter for Lua as a stand-alone language, called simply lua, is provided with the standard distribution. The stand-alone interpreter includes all standard libraries, including the debug library. Its usage is: 

     lua [options] [script [args]]

The options are:

  • -e stat: executes string stat;
  • -l mod: "requires" mod;
  • -i: enters interactive mode after running script;
  • -v: prints version information;
  • --: stops handling options;
  • -: executes stdin as a file and stops handling options.

After handling its options, lua runs the given script, passing to it the given args as string arguments. When called without arguments, lua behaves as lua -v -i when the standard input (stdin) is a terminal, and as lua - otherwise.

Before running any argument, the interpreter checks for an environment variable LUA_INIT. If its format is @filename, then lua executes the file. Otherwise, lua executes the string itself.

All options are handled in order, except -i. For instance, an invocation like 

     $ lua -e'a=1' -e 'print(a)' script.lua

will first set a to 1, then print the value of a (which is '1'), and finally run the file script.lua with no arguments. (Here $ is the shell prompt. Your prompt may be different.)

Before starting to run the script, lua collects all arguments in the command line in a global table called arg. The script name is stored at index 0, the first argument after the script name goes to index 1, and so on. Any arguments before the script name (that is, the interpreter name plus the options) go to negative indices. For instance, in the call 

     $ lua -la b.lua t1 t2

the interpreter first runs the file a.lua, then creates a table 

     arg = { [-2] = "lua", [-1] = "-la",
             [0] = "b.lua",
             [1] = "t1", [2] = "t2" }

and finally runs the file b.lua. The script is called with arg[1], arg[2], ··· as arguments; it can also access these arguments with the vararg expression '...'.

In interactive mode, if you write an incomplete statement, the interpreter waits for its completion by issuing a different prompt.

If the global variable _PROMPT contains a string, then its value is used as the prompt. Similarly, if the global variable _PROMPT2 contains a string, its value is used as the secondary prompt (issued during incomplete statements). Therefore, both prompts can be changed directly on the command line or in any Lua programs by assigning to _PROMPT. See the next example: 

     $ lua -e"_PROMPT='myprompt> '" -i

(The outer pair of quotes is for the shell, the inner pair is for Lua.) Note the use of -i to enter interactive mode; otherwise, the program would just end silently right after the assignment to _PROMPT.

To allow the use of Lua as a script interpreter in Unix systems, the stand-alone interpreter skips the first line of a chunk if it starts with #. Therefore, Lua scripts can be made into executable programs by using chmod +x and the #! form, as in 

     #!/usr/local/bin/lua

(Of course, the location of the Lua interpreter may be different in your machine. If lua is in your PATH, then 

     #!/usr/bin/env lua

is a more portable solution.)

7 - Incompatibilities with the Previous Version

Here we list the incompatibilities that you may find when moving a program from Lua 5.0 to Lua 5.1. You can avoid most of the incompatibilities compiling Lua with appropriate options (see file luaconf.h). However, all these compatibility options will be removed in the next version of Lua.

7.1 - Changes in the Language

  • The vararg system changed from the pseudo-argument arg with a table with the extra arguments to the vararg expression. (See compile-time option LUA_COMPAT_VARARG in luaconf.h.)
  • There was a subtle change in the scope of the implicit variables of the for statement and for the repeat statement.
  • The long string/long comment syntax ([[string]]) does not allow nesting. You can use the new syntax ([=[string]=]) in these cases. (See compile-time option LUA_COMPAT_LSTR in luaconf.h.)

7.2 - Changes in the Libraries

  • Function string.gfind was renamed string.gmatch. (See compile-time option LUA_COMPAT_GFIND in luaconf.h.)
  • When string.gsub is called with a function as its third argument, whenever this function returns nil or false the replacement string is the whole match, instead of the empty string.
  • Function table.setn was deprecated. Function table.getn corresponds to the new length operator (#); use the operator instead of the function. (See compile-time option LUA_COMPAT_GETN in luaconf.h.)
  • Function loadlib was renamed package.loadlib. (See compile-time option LUA_COMPAT_LOADLIB in luaconf.h.)
  • Function math.mod was renamed math.fmod. (See compile-time option LUA_COMPAT_MOD in luaconf.h.)
  • Functions table.foreach and table.foreachi are deprecated. You can use a for loop with pairs or ipairs instead.
  • There were substantial changes in function require due to the new module system. However, the new behavior is mostly compatible with the old, but require gets the path from package.path instead of from LUA_PATH.
  • Function collectgarbage has different arguments. Function gcinfo is deprecated; use collectgarbage("count") instead.

7.3 - Changes in the API

  • The luaopen_* functions (to open libraries) cannot be called directly, like a regular C function. They must be called through Lua, like a Lua function.
  • Function lua_open was replaced by lua_newstate to allow the user to set a memory-allocation function. You can use luaL_newstate from the standard library to create a state with a standard allocation function (based on realloc).
  • Functions luaL_getn and luaL_setn (from the auxiliary library) are deprecated. Use lua_objlen instead of luaL_getn and nothing instead of luaL_setn.
  • Function luaL_openlib was replaced by luaL_register.
  • Function luaL_checkudata now throws an error when the given value is not a userdata of the expected type. (In Lua 5.0 it returned NULL.)

8 - The Complete Syntax of Lua

Here is the complete syntax of Lua in extended BNF. (It does not describe operator precedences.) 


	chunk ::= {stat [`;´]} [laststat [`;´]]

	block ::= chunk

	stat ::=  varlist `=´ explist | 
		 functioncall | 
		 do block end | 
		 while exp do block end | 
		 repeat block until exp | 
		 if exp then block {elseif exp then block} [else block] end | 
		 for Name `=´ exp `,´ exp [`,´ exp] do block end | 
		 for namelist in explist do block end | 
		 function funcname funcbody | 
		 local function Name funcbody | 
		 local namelist [`=´ explist] 

	laststat ::= return [explist] | break

	funcname ::= Name {`.´ Name} [`:´ Name]

	varlist ::= var {`,´ var}

	var ::=  Name | prefixexp `[´ exp `]´ | prefixexp `.´ Name 

	namelist ::= Name {`,´ Name}

	explist ::= {exp `,´} exp

	exp ::=  nil | false | true | Number | String | `...´ | function | 
		 prefixexp | tableconstructor | exp binop exp | unop exp 

	prefixexp ::= var | functioncall | `(´ exp `)´

	functioncall ::=  prefixexp args | prefixexp `:´ Name args 

	args ::=  `(´ [explist] `)´ | tableconstructor | String 

	function ::= function funcbody

	funcbody ::= `(´ [parlist] `)´ block end

	parlist ::= namelist [`,´ `...´] | `...´

	tableconstructor ::= `{´ [fieldlist] `}´

	fieldlist ::= field {fieldsep field} [fieldsep]

	field ::= `[´ exp `]´ `=´ exp | Name `=´ exp | exp

	fieldsep ::= `,´ | `;´

	binop ::= `+´ | `-´ | `*´ | `/´ | `^´ | `%´ | `..´ | 
		 `<´ | `<=´ | `>´ | `>=´ | `==´ | `~=´ |

Drawn by hand by Markus Gritsch . lua.pc pkg-config data for Lua luavs.bat Script to build Lua under "Visual Studio .NET Command Prompt". Run it from the toplevel as etc\luavs.bat. min.c A minimal Lua interpreter. Good for learning and for starting your own. Do "make min" for a demo. noparser.c Linking with noparser.o avoids loading the parsing modules in lualib.a. Do "make noparser" for a demo. strict.lua Traps uses of undeclared global variables.

You can specify a custom pid file location here. pidfile /var/run/redis.pid # Accept connections on the specified port, default is 6379. # If port 0 is specified Redis will not listen on a TCP socket. port 6379 # TCP listen() backlog. # # In high requests-per-second environments you need an high backlog in order # to avoid slow clients connections issues. Note that the Linux kernel # will silently truncate it to the value of /proc/sys/net/core/somaxconn so # make sure to raise both the value of somaxconn and tcp_max_syn_backlog # in order to get the desired effect. tcp-backlog 511 # By default Redis listens for connections from all the network interfaces # available on the server. It is possible to listen to just one or multiple # interfaces using the "bind" configuration directive, followed by one or # more IP addresses. # # Examples: # # bind 192.168.1.100 10.0.0.1 # bind 127.0.0.1 # Specify the path for the Unix socket that will be used to listen for # incoming connections. There is no default, so Redis will not listen # on a unix socket when not specified. # # unixsocket /tmp/redis.sock # unixsocketperm 700 # Close the connection after a client is idle for N seconds (0 to disable) timeout 0 # TCP keepalive. # # If non-zero, use SO_KEEPALIVE to send TCP ACKs to clients in absence # of communication. This is useful for two reasons: # # 1) Detect dead peers. # 2) Take the connection alive from the point of view of network # equipment in the middle. # # On Linux, the specified value (in seconds) is the period used to send ACKs. # Note that to close the connection the double of the time is needed. # On other kernels the period depends on the kernel configuration. # # A reasonable value for this option is 60 seconds. tcp-keepalive 0 # Specify the server verbosity level. # This can be one of: # debug (a lot of information, useful for development/testing) # verbose (many rarely useful info, but not a mess like the debug level) # notice (moderately verbose, what you want in production probably) # warning (only very important / critical messages are logged) loglevel notice # Specify the log file name. Also the empty string can be used to force # Redis to log on the standard output. Note that if you use standard # output for logging but daemonize, logs will be sent to /dev/null logfile "" # To enable logging to the system logger, just set 'syslog-enabled' to yes, # and optionally update the other syslog parameters to suit your needs. # syslog-enabled no # Specify the syslog identity. # syslog-ident redis # Specify the syslog facility.

Use slaveof to make a Redis instance a copy of # another Redis server. A few things to understand ASAP about Redis replication. # # 1) Redis replication is asynchronous, but you can configure a master to # stop accepting writes if it appears to be not connected with at least # a given number of slaves. # 2) Redis slaves are able to perform a partial resynchronization with the # master if the replication link is lost for a relatively small amount of # time. You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. After a # network partition slaves automatically try to reconnect to masters # and resynchronize with them. # # slaveof # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the slave to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the slave request. # # masterauth # When a slave loses its connection with the master, or when the replication # is still in progress, the slave can act in two different ways: # # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will # still reply to client requests, possibly with out of date data, or the # data set may just be empty if this is the first synchronization. # # 2) if slave-serve-stale-data is set to 'no' the slave will reply with # an error "SYNC with master in progress" to all the kind of commands # but to INFO and SLAVEOF. # slave-serve-stale-data yes # You can configure a slave instance to accept writes or not. Writing against # a slave instance may be useful to store some ephemeral data (because data # written on a slave will be easily deleted after resync with the master) but # may also cause problems if clients are writing to it because of a # misconfiguration. # # Since Redis 2.6 by default slaves are read-only. # # Note: read only slaves are not designed to be exposed to untrusted clients # on the internet. It's just a protection layer against misuse of the instance. # Still a read only slave exports by default all the administrative commands # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve # security of read only slaves using 'rename-command' to shadow all the # administrative / dangerous commands. slave-read-only yes # Replication SYNC strategy: disk or socket. # # ------------------------------------------------------- # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY # ------------------------------------------------------- # # New slaves and reconnecting slaves that are not able to continue the replication # process just receiving differences, need to do what is called a "full # synchronization". An RDB file is transmitted from the master to the slaves. # The transmission can happen in two different ways: # # 1) Disk-backed: The Redis master creates a new process that writes the RDB # file on disk. Later the file is transferred by the parent # process to the slaves incrementally. # 2) Diskless: The Redis master creates a new process that directly writes the # RDB file to slave sockets, without touching the disk at all. # # With disk-backed replication, while the RDB file is generated, more slaves # can be queued and served with the RDB file as soon as the current child producing # the RDB file finishes its work. With diskless replication instead once # the transfer starts, new slaves arriving will be queued and a new transfer # will start when the current one terminates. # # When diskless replication is used, the master waits a configurable amount of # time (in seconds) before starting the transfer in the hope that multiple slaves # will arrive and the transfer can be parallelized. # # With slow disks and fast (large bandwidth) networks, diskless replication # works better. repl-diskless-sync no # When diskless replication is enabled, it is possible to configure the delay # the server waits in order to spawn the child that trnasfers the RDB via socket # to the slaves. # # This is important since once the transfer starts, it is not possible to serve # new slaves arriving, that will be queued for the next RDB transfer, so the server # waits a delay in order to let more slaves arrive. # # The delay is specified in seconds, and by default is 5 seconds. To disable # it entirely just set it to 0 seconds and the transfer will start ASAP. repl-diskless-sync-delay 5 # Slaves send PINGs to server in a predefined interval. It's possible to change # this interval with the repl_ping_slave_period option.

But this can add a delay for # the data to appear on the slave side, up to 40 milliseconds with # Linux kernels using a default configuration. # # If you select "no" the delay for data to appear on the slave side will # be reduced but more bandwidth will be used for replication. # # By default we optimize for low latency, but in very high traffic conditions # or when the master and slaves are many hops away, turning this to "yes" may # be a good idea. repl-disable-tcp-nodelay no # Set the replication backlog size. The backlog is a buffer that accumulates # slave data when slaves are disconnected for some time, so that when a slave # wants to reconnect again, often a full resync is not needed, but a partial # resync is enough, just passing the portion of data the slave missed while # disconnected. # # The bigger the replication backlog, the longer the time the slave can be # disconnected and later be able to perform a partial resynchronization. # # The backlog is only allocated once there is at least a slave connected. # # repl-backlog-size 1mb # After a master has no longer connected slaves for some time, the backlog # will be freed.

This might be useful in environments in which you do not trust # others with access to the host running redis-server. # # This should stay commented out for backward compatibility and because most # people do not need auth (e.g. they run their own servers). # # Warning: since Redis is pretty fast an outside user can try up to # 150k passwords per second against a good box. This means that you should # use a very strong password otherwise it will be very easy to break. # # requirepass foobared # Command renaming. # # It is possible to change the name of dangerous commands in a shared # environment.

By default # this limit is set to 10000 clients, however if the Redis server is not # able to configure the process file limit to allow for the specified limit # the max number of allowed clients is set to the current file limit # minus 32 (as Redis reserves a few file descriptors for internal uses). # # Once the limit is reached Redis will close all the new connections sending # an error 'max number of clients reached'. # # maxclients 10000 # Don't use more memory than the specified amount of bytes. # When the memory limit is reached Redis will try to remove keys # according to the eviction policy selected (see maxmemory-policy). # # If Redis can't remove keys according to the policy, or if the policy is # set to 'noeviction', Redis will start to reply with errors to commands # that would use more memory, like SET, LPUSH, and so on, and will continue # to reply to read-only commands like GET. # # This option is usually useful when using Redis as an LRU cache, or to set # a hard memory limit for an instance (using the 'noeviction' policy). # # WARNING: If you have slaves attached to an instance with maxmemory on, # the size of the output buffers needed to feed the slaves are subtracted # from the used memory count, so that network problems / resyncs will # not trigger a loop where keys are evicted, and in turn the output # buffer of slaves is full with DELs of keys evicted triggering the deletion # of more keys, and so forth until the database is completely emptied. # # In short... if you have slaves attached it is suggested that you set a lower # limit for maxmemory so that there is some free RAM on the system for slave # output buffers (but this is not needed if the policy is 'noeviction'). # # maxmemory # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory # is reached. You can select among five behaviors: # # volatile-lru -> remove the key with an expire set using an LRU algorithm # allkeys-lru -> remove any key according to the LRU algorithm # volatile-random -> remove a random key with an expire set # allkeys-random -> remove a random key, any key # volatile-ttl -> remove the key with the nearest expire time (minor TTL) # noeviction -> don't expire at all, just return an error on write operations # # Note: with any of the above policies, Redis will return an error on write # operations, when there are no suitable keys for eviction. # # At the date of writing these commands are: set setnx setex append # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby # getset mset msetnx exec sort # # The default is: # # maxmemory-policy volatile-lru # LRU and minimal TTL algorithms are not precise algorithms but approximated # algorithms (in order to save memory), so you can select as well the sample # size to check.

This mode is # good enough in many applications, but an issue with the Redis process or # a power outage may result into a few minutes of writes lost (depending on # the configured save points). # # The Append Only File is an alternative persistence mode that provides # much better durability. For instance using the default data fsync policy # (see later in the config file) Redis can lose just one second of writes in a # dramatic event like a server power outage, or a single write if something # wrong with the Redis process itself happens, but the operating system is # still running correctly. # # AOF and RDB persistence can be enabled at the same time without problems. # If the AOF is enabled on startup Redis will load the AOF, that is the file # with the better durability guarantees. # # Please check http://redis.io/topics/persistence for more information. appendonly no # The name of the append only file (default: "appendonly.aof") appendfilename "appendonly.aof" # The fsync() call tells the Operating System to actually write data on disk # instead of waiting for more data in the output buffer. Some OS will really flush # data on disk, some other OS will just try to do it ASAP. # # Redis supports three different modes: # # no: don't fsync, just let the OS flush the data when it wants. Faster. # always: fsync after every write to the append only log. Slow, Safest. # everysec: fsync only one time every second. Compromise. # # The default is "everysec", as that's usually the right compromise between # speed and data safety. It's up to you to understand if you can relax this to # "no" that will let the operating system flush the output buffer when # it wants, for better performances (but if you can live with the idea of # some data loss consider the default persistence mode that's snapshotting), # or on the contrary, use "always" that's very slow but a bit safer than # everysec. # # More details please check the following article: # http://antirez.com/post/redis-persistence-demystified.html # # If unsure, use "everysec". # appendfsync always appendfsync everysec # appendfsync no # When the AOF fsync policy is set to always or everysec, and a background # saving process (a background save or AOF log background rewriting) is # performing a lot of I/O against the disk, in some Linux configurations # Redis may block too long on the fsync() call.

In practical terms, this means that it is # possible to lose up to 30 seconds of log in the worst scenario (with the # default Linux settings). # # If you have latency problems turn this to "yes".

If the current size is # bigger than the specified percentage, the rewrite is triggered. Also # you need to specify a minimal size for the AOF file to be rewritten, this # is useful to avoid rewriting the AOF file even if the percentage increase # is reached but it is still pretty small. # # Specify a percentage of zero in order to disable the automatic AOF # rewrite feature. auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb # An AOF file may be found to be truncated at the end during the Redis # startup process, when the AOF data gets loaded back into memory. # This may happen when the system where Redis is running # crashes, especially when an ext4 filesystem is mounted without the # data=ordered option (however this can't happen when Redis itself # crashes or aborts but the operating system still works correctly). # # Redis can either exit with an error when this happens, or load as much # data as possible (the default now) and start if the AOF file is found # to be truncated at the end.

When a new command is logged the oldest one is removed from the # queue of logged commands. # The following time is expressed in microseconds, so 1000000 is equivalent # to one second.

After this limit is # reached the script is terminated with a SIGKILL and the execution retried. # NOTIFICATION SCRIPT # # sentinel notification-script # # Call the specified notification script for any sentinel event that is # generated in the WARNING level (for instance -sdown, -odown, and so forth). # This script should notify the system administrator via email, SMS, or any # other messaging system, that there is something wrong with the monitored # Redis systems. # # The script is called with just two arguments: the first is the event type # and the second the event description. # # The script must exist and be executable in order for sentinel to start if # this option is provided. # # Example: # # sentinel notification-script mymaster /var/redis/notify.sh # CLIENTS RECONFIGURATION SCRIPT # # sentinel client-reconfig-script # # When the master changed because of a failover a script can be called in # order to perform application-specific tasks to notify the clients that the # configuration has changed and the master is at a different address. # # The following arguments are passed to the script: # # # # is currently always "failover" # is either "leader" or "observer" # # The arguments from-ip, from-port, to-ip, to-port are used to communicate # the old address of the master and the new address of the elected slave # (now a master). # # This script should be resistant to multiple invocations. # # Example: # # sentinel client-reconfig-script mymaster /var/redis/reconfig.sh ================================================ FILE: extern/deprecated/redis-2.8.21/src/.gitignore ================================================ *.gcda *.gcno *.gcov redis.info lcov-html ================================================ FILE: extern/deprecated/redis-2.8.21/src/Makefile ================================================ # Redis Makefile # Copyright (C) 2009 Salvatore Sanfilippo # This file is released under the BSD license, see the COPYING file # # The Makefile composes the final FINAL_CFLAGS and FINAL_LDFLAGS using # what is needed for Redis plus the standard CFLAGS and LDFLAGS passed. # However when building the dependencies (Jemalloc, Lua, Hiredis, ...) # CFLAGS and LDFLAGS are propagated to the dependencies, so to pass # flags only to be used when compiling / linking Redis itself REDIS_CFLAGS # and REDIS_LDFLAGS are used instead (this is the case of 'make gcov'). # # Dependencies are stored in the Makefile.dep file.

That is, instead of incrementing the cursor normally, the bits * of the cursor are reversed, then the cursor is incremented, and finally * the bits are reversed again. * * This strategy is needed because the hash table may be resized between * iteration calls. * * dict.c hash tables are always power of two in size, and they * use chaining, so the position of an element in a given table is given * by computing the bitwise AND between Hash(key) and SIZE-1 * (where SIZE-1 is always the mask that is equivalent to taking the rest * of the division between the Hash of the key and SIZE). * * For example if the current hash table size is 16, the mask is * (in binary) 1111. The position of a key in the hash table will always be * the last four bits of the hash output, and so forth. * * WHAT HAPPENS IF THE TABLE CHANGES IN SIZE? * * If the hash table grows, elements can go anywhere in one multiple of * the old bucket: for example let's say we already iterated with * a 4 bit cursor 1100 (the mask is 1111 because hash table size = 16). * * If the hash table will be resized to 64 elements, then the new mask will * be 111111. The new buckets you obtain by substituting in ??1100 * with either 0 or 1 can be targeted only by keys we already visited * when scanning the bucket 1100 in the smaller hash table. * * By iterating the higher bits first, because of the inverted counter, the * cursor does not need to restart if the table size gets bigger. It will * continue iterating using cursors without '1100' at the end, and also * without any other combination of the final 4 bits already explored. * * Similarly when the table size shrinks over time, for example going from * 16 to 8, if a combination of the lower three bits (the mask for size 8 * is 111) were already completely explored, it would not be visited again * because we are sure we tried, for example, both 0111 and 1111 (all the * variations of the higher bit) so we don't need to test it again. * * WAIT... YOU HAVE *TWO* TABLES DURING REHASHING! * * Yes, this is true, but we always iterate the smaller table first, then * we test all the expansions of the current cursor into the larger * table. For example if the current cursor is 101 and we also have a * larger table of size 16, we also test (0)101 and (1)101 inside the larger * table. This reduces the problem back to having only one table, where * the larger one, if it exists, is just an expansion of the smaller one. * * LIMITATIONS * * This iterator is completely stateless, and this is a huge advantage, * including no additional memory used. * * The disadvantages resulting from this design are: * * 1) It is possible we return elements more than once. However this is usually * easy to deal with in the application level. * 2) The iterator must return multiple elements per call, as it needs to always * return all the keys chained in a given bucket, and all the expansions, so * we are sure we don't miss keys moving during rehashing. * 3) The reverse cursor is somewhat hard to understand at first, but this * comment is supposed to help. */ unsigned long dictScan(dict *d, unsigned long v, dictScanFunction *fn, void *privdata) { dictht *t0, *t1; const dictEntry *de; unsigned long m0, m1; if (dictSize(d) == 0) return 0; if (!dictIsRehashing(d)) { t0 = &(d->ht[0]); m0 = t0->sizemask; /* Emit entries at cursor */ de = t0->table[v & m0]; while (de) { fn(privdata, de); de = de->next; } } else { t0 = &d->ht[0]; t1 = &d->ht[1]; /* Make sure t0 is the smaller and t1 is the bigger table */ if (t0->size > t1->size) { t0 = &d->ht[1]; t1 = &d->ht[0]; } m0 = t0->sizemask; m1 = t1->sizemask; /* Emit entries at cursor */ de = t0->table[v & m0]; while (de) { fn(privdata, de); de = de->next; } /* Iterate over indices in larger table that are the expansion * of the index pointed to by the cursor in the smaller table */ do { /* Emit entries at cursor */ de = t1->table[v & m1]; while (de) { fn(privdata, de); de = de->next; } /* Increment bits not covered by the smaller mask */ v = (((v | m0) + 1) & ~m0) | (v & m0); /* Continue while bits covered by mask difference is non-zero */ } while (v & (m0 ^ m1)); } /* Set unmasked bits so incrementing the reversed cursor * operates on the masked bits of the smaller table */ v |= ~m0; /* Increment the reverse cursor */ v = rev(v); v++; v = rev(v); return v; } /* ------------------------- private functions ------------------------------ */ /* Expand the hash table if needed */ static int _dictExpandIfNeeded(dict *d) { /* Incremental rehashing already in progress.

No new type is introduced. * * No attempt is made to compress the data structure as in [1]. Also the * algorithm used is the original HyperLogLog Algorithm as in [2], with * the only difference that a 64 bit hash function is used, so no correction * is performed for values near 2^32 as in [1]. * * [1] Heule, Nunkesser, Hall: HyperLogLog in Practice: Algorithmic * Engineering of a State of The Art Cardinality Estimation Algorithm. * * [2] P. Flajolet, Éric Fusy, O. Gandouet, and F. Meunier. Hyperloglog: The * analysis of a near-optimal cardinality estimation algorithm. * * Redis uses two representations: * * 1) A "dense" representation where every entry is represented by * a 6-bit integer. * 2) A "sparse" representation using run length compression suitable * for representing HyperLogLogs with many registers set to 0 in * a memory efficient way. * * * HLL header * === * * Both the dense and sparse representation have a 16 byte header as follows: * * +------+---+-----+----------+ * | HYLL | E | N/U | Cardin. | * +------+---+-----+----------+ * * The first 4 bytes are a magic string set to the bytes "HYLL". * "E" is one byte encoding, currently set to HLL_DENSE or * HLL_SPARSE. N/U are three not used bytes. * * The "Cardin." field is a 64 bit integer stored in little endian format * with the latest cardinality computed that can be reused if the data * structure was not modified since the last computation (this is useful * because there are high probabilities that HLLADD operations don't * modify the actual data structure and hence the approximated cardinality). * * When the most significant bit in the most significant byte of the cached * cardinality is set, it means that the data structure was modified and * we can't reuse the cached value that must be recomputed. * * Dense representation * === * * The dense representation used by Redis is the following: * * +--------+--------+--------+------// //--+ * |11000000|22221111|33333322|55444444 .... | * +--------+--------+--------+------// //--+ * * The 6 bits counters are encoded one after the other starting from the * LSB to the MSB, and using the next bytes as needed. * * Sparse representation * === * * The sparse representation encodes registers using a run length * encoding composed of three opcodes, two using one byte, and one using * of two bytes. The opcodes are called ZERO, XZERO and VAL. * * ZERO opcode is represented as 00xxxxxx. The 6-bit integer represented * by the six bits 'xxxxxx', plus 1, means that there are N registers set * to 0. This opcode can represent from 1 to 64 contiguous registers set * to the value of 0. * * XZERO opcode is represented by two bytes 01xxxxxx yyyyyyyy. The 14-bit * integer represented by the bits 'xxxxxx' as most significant bits and * 'yyyyyyyy' as least significant bits, plus 1, means that there are N * registers set to 0. This opcode can represent from 0 to 16384 contiguous * registers set to the value of 0. * * VAL opcode is represented as 1vvvvvxx. It contains a 5-bit integer * representing the value of a register, and a 2-bit integer representing * the number of contiguous registers set to that value 'vvvvv'. * To obtain the value and run length, the integers vvvvv and xx must be * incremented by one. This opcode can represent values from 1 to 32, * repeated from 1 to 4 times. * * The sparse representation can't represent registers with a value greater * than 32, however it is very unlikely that we find such a register in an * HLL with a cardinality where the sparse representation is still more * memory efficient than the dense representation. When this happens the * HLL is converted to the dense representation. * * The sparse representation is purely positional. For example a sparse * representation of an empty HLL is just: XZERO:16384. * * An HLL having only 3 non-zero registers at position 1000, 1020, 1021 * respectively set to 2, 3, 3, is represented by the following three * opcodes: * * XZERO:1000 (Registers 0-999 are set to 0) * VAL:2,1 (1 register set to value 2, that is register 1000) * ZERO:19 (Registers 1001-1019 set to 0) * VAL:3,2 (2 registers set to value 3, that is registers 1020,1021) * XZERO:15362 (Registers 1022-16383 set to 0) * * In the example the sparse representation used just 7 bytes instead * of 12k in order to represent the HLL registers. In general for low * cardinality there is a big win in terms of space efficiency, traded * with CPU time since the sparse representation is slower to access: * * The following table shows average cardinality vs bytes used, 100 * samples per cardinality (when the set was not representable because * of registers with too big value, the dense representation size was used * as a sample). * * 100 267 * 200 485 * 300 678 * 400 859 * 500 1033 * 600 1205 * 700 1375 * 800 1544 * 900 1713 * 1000 1882 * 2000 3480 * 3000 4879 * 4000 6089 * 5000 7138 * 6000 8042 * 7000 8823 * 8000 9500 * 9000 10088 * 10000 10591 * * The dense representation uses 12288 bytes, so there is a big win up to * a cardinality of ~2000-3000. For bigger cardinalities the constant times * involved in updating the sparse representation is not justified by the * memory savings. The exact maximum length of the sparse representation * when this implementation switches to the dense representation is * configured via the define server.hll_sparse_max_bytes. */ struct hllhdr { char magic[4]; /* "HYLL" */ uint8_t encoding; /* HLL_DENSE or HLL_SPARSE. */ uint8_t notused[3]; /* Reserved for future use, must be zero. */ uint8_t card[8]; /* Cached cardinality, little endian. */ uint8_t registers[]; /* Data bytes. */ }; /* The cached cardinality MSB is used to signal validity of the cached value. */ #define HLL_INVALIDATE_CACHE(hdr) (hdr)->card[7] |= (1<<7) #define HLL_VALID_CACHE(hdr) (((hdr)->card[7] & (1<<7)) == 0) #define HLL_P 14 /* The greater is P, the smaller the error. */ #define HLL_REGISTERS (1< 6 * * Right shift b0 of 'fb' bits. * * +--------+ * |11000000| <- Initial value of b0 * |00000011| <- After right shift of 6 pos. * +--------+ * * Left shift b1 of bits 8-fb bits (2 bits) * * +--------+ * |22221111| <- Initial value of b1 * |22111100| <- After left shift of 2 bits. * +--------+ * * OR the two bits, and finally AND with 111111 (63 in decimal) to * clean the higher order bits we are not interested in: * * +--------+ * |00000011| <- b0 right shifted * |22111100| <- b1 left shifted * |22111111| <- b0 OR b1 * | 111111| <- (b0 OR b1) AND 63, our value. * +--------+ * * We can try with a different example, like pos = 0.

The allocated space is suitably aligned (after possible pointer coercion) for storage of any type of object. The calloc function allocates space for number objects, each size bytes in length. The result is identical to calling malloc with an argument of number * size, with the exception that the allocated memory is explicitly initialized to zero bytes. The posix_memalign function allocates size bytes of memory such that the allocation's base address is a multiple of alignment, and returns the allocation in the value pointed to by ptr. The requested alignment must be a power of 2 at least as large as sizeof(void *). The aligned_alloc function allocates size bytes of memory such that the allocation's base address is a multiple of alignment. The requested alignment must be a power of 2. Behavior is undefined if size is not an integral multiple of alignment. The realloc function changes the size of the previously allocated memory referenced by ptr to size bytes. The contents of the memory are unchanged up to the lesser of the new and old sizes. If the new size is larger, the contents of the newly allocated portion of the memory are undefined. Upon success, the memory referenced by ptr is freed and a pointer to the newly allocated memory is returned. Note that realloc may move the memory allocation, resulting in a different return value than ptr. If ptr is NULL, the realloc function behaves identically to malloc for the specified size. The free function causes the allocated memory referenced by ptr to be made available for future allocations. If ptr is NULL, no action occurs. Non-standard API The mallocx, rallocx, xallocx, sallocx, dallocx, sdallocx, and nallocx functions all have a flags argument that can be used to specify options. The functions only check the options that are contextually relevant. Use bitwise or (|) operations to specify one or more of the following: MALLOCX_LG_ALIGN(la) Align the memory allocation to start at an address that is a multiple of (1 << la). This macro does not validate that la is within the valid range. MALLOCX_ALIGN(a) Align the memory allocation to start at an address that is a multiple of a, where a is a power of two. This macro does not validate that a is a power of 2. MALLOCX_ZERO Initialize newly allocated memory to contain zero bytes. In the growing reallocation case, the real size prior to reallocation defines the boundary between untouched bytes and those that are initialized to contain zero bytes. If this macro is absent, newly allocated memory is uninitialized. MALLOCX_TCACHE(tc) Use the thread-specific cache (tcache) specified by the identifier tc, which must have been acquired via the tcache.create mallctl. This macro does not validate that tc specifies a valid identifier. MALLOCX_TCACHE_NONE Do not use a thread-specific cache (tcache). Unless MALLOCX_TCACHE(tc) or MALLOCX_TCACHE_NONE is specified, an automatically managed tcache will be used under many circumstances. This macro cannot be used in the same flags argument as MALLOCX_TCACHE(tc). MALLOCX_ARENA(a) Use the arena specified by the index a. This macro has no effect for regions that were allocated via an arena other than the one specified. This macro does not validate that a specifies an arena index in the valid range. The mallocx function allocates at least size bytes of memory, and returns a pointer to the base address of the allocation. Behavior is undefined if size is 0. The rallocx function resizes the allocation at ptr to be at least size bytes, and returns a pointer to the base address of the resulting allocation, which may or may not have moved from its original location. Behavior is undefined if size is 0. The xallocx function resizes the allocation at ptr in place to be at least size bytes, and returns the real size of the allocation. If extra is non-zero, an attempt is made to resize the allocation to be at least (size + extra) bytes, though inability to allocate the extra byte(s) will not by itself result in failure to resize. Behavior is undefined if size is 0, or if (size + extra > SIZE_T_MAX). The sallocx function returns the real size of the allocation at ptr. The dallocx function causes the memory referenced by ptr to be made available for future allocations. The sdallocx function is an extension of dallocx with a size parameter to allow the caller to pass in the allocation size as an optimization. The minimum valid input size is the original requested size of the allocation, and the maximum valid input size is the corresponding value returned by nallocx or sallocx. The nallocx function allocates no memory, but it performs the same size computation as the mallocx function, and returns the real size of the allocation that would result from the equivalent mallocx function call, or 0 if the inputs exceed the maximum supported size class and/or alignment. Behavior is undefined if size is 0. The mallctl function provides a general interface for introspecting the memory allocator, as well as setting modifiable parameters and triggering actions. The period-separated name argument specifies a location in a tree-structured namespace; see the section for documentation on the tree contents. To read a value, pass a pointer via oldp to adequate space to contain the value, and a pointer to its length via oldlenp; otherwise pass NULL and NULL. Similarly, to write a value, pass a pointer to the value via newp, and its length via newlen; otherwise pass NULL and 0. The mallctlnametomib function provides a way to avoid repeated name lookups for applications that repeatedly query the same portion of the namespace, by translating a name to a “Management Information Base” (MIB) that can be passed repeatedly to mallctlbymib. Upon successful return from mallctlnametomib, mibp contains an array of *miblenp integers, where *miblenp is the lesser of the number of components in name and the input value of *miblenp. Thus it is possible to pass a *miblenp that is smaller than the number of period-separated name components, which results in a partial MIB that can be used as the basis for constructing a complete MIB. For name components that are integers (e.g. the 2 in arenas.bin.2.size), the corresponding MIB component will always be that integer. Therefore, it is legitimate to construct code like the following: The malloc_stats_print function writes human-readable summary statistics via the write_cb callback function pointer and cbopaque data passed to write_cb, or malloc_message if write_cb is NULL. This function can be called repeatedly. General information that never changes during execution can be omitted by specifying "g" as a character within the opts string. Note that malloc_message uses the mallctl* functions internally, so inconsistent statistics can be reported if multiple threads use these functions simultaneously. If is specified during configuration, “m” and “a” can be specified to omit merged arena and per arena statistics, respectively; “b”, “l”, and “h” can be specified to omit per size class statistics for bins, large objects, and huge objects, respectively. Unrecognized characters are silently ignored. Note that thread caching may prevent some statistics from being completely up to date, since extra locking would be required to merge counters that track thread cache operations. The malloc_usable_size function returns the usable size of the allocation pointed to by ptr. The return value may be larger than the size that was requested during allocation. The malloc_usable_size function is not a mechanism for in-place realloc; rather it is provided solely as a tool for introspection purposes. Any discrepancy between the requested allocation size and the size reported by malloc_usable_size should not be depended on, since such behavior is entirely implementation-dependent. TUNING Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile- or run-time. The string specified via , the string pointed to by the global variable malloc_conf, the “name” of the file referenced by the symbolic link named /etc/malloc.conf, and the value of the environment variable MALLOC_CONF, will be interpreted, in that order, from left to right as options. Note that malloc_conf may be read before main is entered, so the declaration of malloc_conf should specify an initializer that contains the final value to be read by jemalloc. and malloc_conf are compile-time mechanisms, whereas /etc/malloc.conf and MALLOC_CONF can be safely set any time prior to program invocation. An options string is a comma-separated list of option:value pairs. There is one key corresponding to each opt.* mallctl (see the section for options documentation). For example, abort:true,narenas:1 sets the opt.abort and opt.narenas options. Some options have boolean values (true/false), others have integer values (base 8, 10, or 16, depending on prefix), and yet others have raw string values. IMPLEMENTATION NOTES Traditionally, allocators have used sbrk 2 to obtain memory, which is suboptimal for several reasons, including race conditions, increased fragmentation, and artificial limitations on maximum usable memory. If sbrk 2 is supported by the operating system, this allocator uses both mmap 2 and sbrk 2, in that order of preference; otherwise only mmap 2 is used. This allocator uses multiple arenas in order to reduce lock contention for threaded programs on multi-processor systems. This works well with regard to threading scalability, but incurs some costs. There is a small fixed per-arena overhead, and additionally, arenas manage memory completely independently of each other, which means a small fixed increase in overall memory fragmentation. These overheads are not generally an issue, given the number of arenas normally used. Note that using substantially more arenas than the default is not likely to improve performance, mainly due to reduced cache performance. However, it may make sense to reduce the number of arenas if an application does not make much use of the allocation functions. In addition to multiple arenas, unless is specified during configuration, this allocator supports thread-specific caching for small and large objects, in order to make it possible to completely avoid synchronization for most allocation requests. Such caching allows very fast allocation in the common case, but it increases memory usage and fragmentation, since a bounded number of objects can remain allocated in each thread cache. Memory is conceptually broken into equal-sized chunks, where the chunk size is a power of two that is greater than the page size. Chunks are always aligned to multiples of the chunk size. This alignment makes it possible to find metadata for user objects very quickly. User objects are broken into three categories according to size: small, large, and huge. Multiple small and large objects can reside within a single chunk, whereas huge objects each have one or more chunks backing them. Each chunk that contains small and/or large objects tracks its contents as runs of contiguous pages (unused, backing a set of small objects, or backing one large object). The combination of chunk alignment and chunk page maps makes it possible to determine all metadata regarding small and large allocations in constant time. Small objects are managed in groups by page runs. Each run maintains a bitmap to track which regions are in use. Allocation requests that are no more than half the quantum (8 or 16, depending on architecture) are rounded up to the nearest power of two that is at least sizeof(double). All other object size classes are multiples of the quantum, spaced such that there are four size classes for each doubling in size, which limits internal fragmentation to approximately 20% for all but the smallest size classes. Small size classes are smaller than four times the page size, large size classes are smaller than the chunk size (see the opt.lg_chunk option), and huge size classes extend from the chunk size up to the largest size class that does not exceed PTRDIFF_MAX. Allocations are packed tightly together, which can be an issue for multi-threaded applications. If you need to assure that allocations do not suffer from cacheline sharing, round your allocation requests up to the nearest multiple of the cacheline size, or specify cacheline alignment when allocating. The realloc, rallocx, and xallocx functions may resize allocations without moving them under limited circumstances. Unlike the *allocx API, the standard API does not officially round up the usable size of an allocation to the nearest size class, so technically it is necessary to call realloc to grow e.g. a 9-byte allocation to 16 bytes, or shrink a 16-byte allocation to 9 bytes. Growth and shrinkage trivially succeeds in place as long as the pre-size and post-size both round up to the same size class. No other API guarantees are made regarding in-place resizing, but the current implementation also tries to resize large and huge allocations in place, as long as the pre-size and post-size are both large or both huge. In such cases shrinkage always succeeds for large size classes, but for huge size classes the chunk allocator must support splitting (see arena.<i>.chunk_hooks). Growth only succeeds if the trailing memory is currently available, and additionally for huge size classes the chunk allocator must support merging. Assuming 2 MiB chunks, 4 KiB pages, and a 16-byte quantum on a 64-bit system, the size classes in each category are as shown in .

MALLCTL NAMESPACE The following names are defined in the namespace accessible via the mallctl* functions. Value types are specified in parentheses, their readable/writable statuses are encoded as rw, r-, -w, or --, and required build configuration flags follow, if any. A name element encoded as <i> or <j> indicates an integer component, where the integer varies from 0 to some upper value that must be determined via introspection. In the case of stats.arenas.<i>.*, <i> equal to arenas.narenas can be used to access the summation of statistics from all arenas. Take special note of the epoch mallctl, which controls refreshing of cached dynamic statistics. version (const char *) r- Return the jemalloc version string. epoch (uint64_t) rw If a value is passed in, refresh the data from which the mallctl* functions report values, and increment the epoch. Return the current epoch. This is useful for detecting whether another thread caused a refresh. config.cache_oblivious (bool) r- was specified during build configuration. config.debug (bool) r- was specified during build configuration. config.fill (bool) r- was specified during build configuration. config.lazy_lock (bool) r- was specified during build configuration. config.malloc_conf (const char *) r- Embedded configure-time-specified run-time options string, empty unless was specified during build configuration. config.munmap (bool) r- was specified during build configuration. config.prof (bool) r- was specified during build configuration. config.prof_libgcc (bool) r- was not specified during build configuration. config.prof_libunwind (bool) r- was specified during build configuration. config.stats (bool) r- was specified during build configuration. config.tcache (bool) r- was not specified during build configuration. config.tls (bool) r- was not specified during build configuration. config.utrace (bool) r- was specified during build configuration. config.valgrind (bool) r- was specified during build configuration. config.xmalloc (bool) r- was specified during build configuration. opt.abort (bool) r- Abort-on-warning enabled/disabled. If true, most warnings are fatal. The process will call abort 3 in these cases. This option is disabled by default unless is specified during configuration, in which case it is enabled by default. opt.dss (const char *) r- dss (sbrk 2) allocation precedence as related to mmap 2 allocation. The following settings are supported if sbrk 2 is supported by the operating system: “disabled”, “primary”, and “secondary”; otherwise only “disabled” is supported. The default is “secondary” if sbrk 2 is supported by the operating system; “disabled” otherwise. opt.lg_chunk (size_t) r- Virtual memory chunk size (log base 2). If a chunk size outside the supported size range is specified, the size is silently clipped to the minimum/maximum supported size. The default chunk size is 2 MiB (2^21). opt.narenas (unsigned) r- Maximum number of arenas to use for automatic multiplexing of threads and arenas. The default is four times the number of CPUs, or one if there is a single CPU. opt.purge (const char *) r- Purge mode is “ratio” (default) or “decay”. See opt.lg_dirty_mult for details of the ratio mode. See opt.decay_time for details of the decay mode. opt.lg_dirty_mult (ssize_t) r- Per-arena minimum ratio (log base 2) of active to dirty pages. Some dirty unused pages may be allowed to accumulate, within the limit set by the ratio (or one chunk worth of dirty pages, whichever is greater), before informing the kernel about some of those pages via madvise 2 or a similar system call. This provides the kernel with sufficient information to recycle dirty pages if physical memory becomes scarce and the pages remain unused. The default minimum ratio is 8:1 (2^3:1); an option value of -1 will disable dirty page purging. See arenas.lg_dirty_mult and arena.<i>.lg_dirty_mult for related dynamic control options. opt.decay_time (ssize_t) r- Approximate time in seconds from the creation of a set of unused dirty pages until an equivalent set of unused dirty pages is purged and/or reused. The pages are incrementally purged according to a sigmoidal decay curve that starts and ends with zero purge rate. A decay time of 0 causes all unused dirty pages to be purged immediately upon creation. A decay time of -1 disables purging. The default decay time is 10 seconds. See arenas.decay_time and arena.<i>.decay_time for related dynamic control options. opt.stats_print (bool) r- Enable/disable statistics printing at exit. If enabled, the malloc_stats_print function is called at program exit via an atexit 3 function. If is specified during configuration, this has the potential to cause deadlock for a multi-threaded process that exits while one or more threads are executing in the memory allocation functions. Furthermore, atexit may allocate memory during application initialization and then deadlock internally when jemalloc in turn calls atexit, so this option is not universally usable (though the application can register its own atexit function with equivalent functionality). Therefore, this option should only be used with care; it is primarily intended as a performance tuning aid during application development. This option is disabled by default. opt.junk (const char *) r- [] Junk filling. If set to "alloc", each byte of uninitialized allocated memory will be initialized to 0xa5. If set to "free", all deallocated memory will be initialized to 0x5a. If set to "true", both allocated and deallocated memory will be initialized, and if set to "false", junk filling be disabled entirely. This is intended for debugging and will impact performance negatively. This option is "false" by default unless is specified during configuration, in which case it is "true" by default unless running inside Valgrind. opt.quarantine (size_t) r- [] Per thread quarantine size in bytes. If non-zero, each thread maintains a FIFO object quarantine that stores up to the specified number of bytes of memory. The quarantined memory is not freed until it is released from quarantine, though it is immediately junk-filled if the opt.junk option is enabled. This feature is of particular use in combination with Valgrind, which can detect attempts to access quarantined objects. This is intended for debugging and will impact performance negatively. The default quarantine size is 0 unless running inside Valgrind, in which case the default is 16 MiB. opt.redzone (bool) r- [] Redzones enabled/disabled. If enabled, small allocations have redzones before and after them. Furthermore, if the opt.junk option is enabled, the redzones are checked for corruption during deallocation. However, the primary intended purpose of this feature is to be used in combination with Valgrind, which needs redzones in order to do effective buffer overflow/underflow detection. This option is intended for debugging and will impact performance negatively. This option is disabled by default unless running inside Valgrind. opt.zero (bool) r- [] Zero filling enabled/disabled. If enabled, each byte of uninitialized allocated memory will be initialized to 0. Note that this initialization only happens once for each byte, so realloc and rallocx calls do not zero memory that was previously allocated. This is intended for debugging and will impact performance negatively. This option is disabled by default. opt.utrace (bool) r- [] Allocation tracing based on utrace 2 enabled/disabled. This option is disabled by default. opt.xmalloc (bool) r- [] Abort-on-out-of-memory enabled/disabled. If enabled, rather than returning failure for any allocation function, display a diagnostic message on STDERR_FILENO and cause the program to drop core (using abort 3). If an application is designed to depend on this behavior, set the option at compile time by including the following in the source code: This option is disabled by default. opt.tcache (bool) r- [] Thread-specific caching (tcache) enabled/disabled. When there are multiple threads, each thread uses a tcache for objects up to a certain size. Thread-specific caching allows many allocations to be satisfied without performing any thread synchronization, at the cost of increased memory use. See the opt.lg_tcache_max option for related tuning information. This option is enabled by default unless running inside Valgrind, in which case it is forcefully disabled. opt.lg_tcache_max (size_t) r- [] Maximum size class (log base 2) to cache in the thread-specific cache (tcache). At a minimum, all small size classes are cached, and at a maximum all large size classes are cached. The default maximum is 32 KiB (2^15). opt.prof (bool) r- [] Memory profiling enabled/disabled. If enabled, profile memory allocation activity. See the opt.prof_active option for on-the-fly activation/deactivation. See the opt.lg_prof_sample option for probabilistic sampling control. See the opt.prof_accum option for control of cumulative sample reporting. See the opt.lg_prof_interval option for information on interval-triggered profile dumping, the opt.prof_gdump option for information on high-water-triggered profile dumping, and the opt.prof_final option for final profile dumping. Profile output is compatible with the jeprof command, which is based on the pprof that is developed as part of the gperftools package. See HEAP PROFILE FORMAT for heap profile format documentation. opt.prof_prefix (const char *) r- [] Filename prefix for profile dumps. If the prefix is set to the empty string, no automatic dumps will occur; this is primarily useful for disabling the automatic final heap dump (which also disables leak reporting, if enabled). The default prefix is jeprof. opt.prof_active (bool) r- [] Profiling activated/deactivated. This is a secondary control mechanism that makes it possible to start the application with profiling enabled (see the opt.prof option) but inactive, then toggle profiling at any time during program execution with the prof.active mallctl. This option is enabled by default. opt.prof_thread_active_init (bool) r- [] Initial setting for thread.prof.active in newly created threads. The initial setting for newly created threads can also be changed during execution via the prof.thread_active_init mallctl. This option is enabled by default. opt.lg_prof_sample (size_t) r- [] Average interval (log base 2) between allocation samples, as measured in bytes of allocation activity. Increasing the sampling interval decreases profile fidelity, but also decreases the computational overhead. The default sample interval is 512 KiB (2^19 B). opt.prof_accum (bool) r- [] Reporting of cumulative object/byte counts in profile dumps enabled/disabled. If this option is enabled, every unique backtrace must be stored for the duration of execution. Depending on the application, this can impose a large memory overhead, and the cumulative counts are not always of interest. This option is disabled by default. opt.lg_prof_interval (ssize_t) r- [] Average interval (log base 2) between memory profile dumps, as measured in bytes of allocation activity. The actual interval between dumps may be sporadic because decentralized allocation counters are used to avoid synchronization bottlenecks. Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.i<iseq>.heap, where <prefix> is controlled by the opt.prof_prefix option. By default, interval-triggered profile dumping is disabled (encoded as -1). opt.prof_gdump (bool) r- [] Set the initial state of prof.gdump, which when enabled triggers a memory profile dump every time the total virtual memory exceeds the previous maximum. This option is disabled by default. opt.prof_final (bool) r- [] Use an atexit 3 function to dump final memory usage to a file named according to the pattern <prefix>.<pid>.<seq>.f.heap, where <prefix> is controlled by the opt.prof_prefix option. Note that atexit may allocate memory during application initialization and then deadlock internally when jemalloc in turn calls atexit, so this option is not universally usable (though the application can register its own atexit function with equivalent functionality). This option is disabled by default. opt.prof_leak (bool) r- [] Leak reporting enabled/disabled. If enabled, use an atexit 3 function to report memory leaks detected by allocation sampling. See the opt.prof option for information on analyzing heap profile output. This option is disabled by default. thread.arena (unsigned) rw Get or set the arena associated with the calling thread. If the specified arena was not initialized beforehand (see the arenas.initialized mallctl), it will be automatically initialized as a side effect of calling this interface. thread.allocated (uint64_t) r- [] Get the total number of bytes ever allocated by the calling thread. This counter has the potential to wrap around; it is up to the application to appropriately interpret the counter in such cases. thread.allocatedp (uint64_t *) r- [] Get a pointer to the the value that is returned by the thread.allocated mallctl. This is useful for avoiding the overhead of repeated mallctl* calls. thread.deallocated (uint64_t) r- [] Get the total number of bytes ever deallocated by the calling thread. This counter has the potential to wrap around; it is up to the application to appropriately interpret the counter in such cases. thread.deallocatedp (uint64_t *) r- [] Get a pointer to the the value that is returned by the thread.deallocated mallctl. This is useful for avoiding the overhead of repeated mallctl* calls. thread.tcache.enabled (bool) rw [] Enable/disable calling thread's tcache. The tcache is implicitly flushed as a side effect of becoming disabled (see thread.tcache.flush). thread.tcache.flush (void) -- [] Flush calling thread's thread-specific cache (tcache). This interface releases all cached objects and internal data structures associated with the calling thread's tcache. Ordinarily, this interface need not be called, since automatic periodic incremental garbage collection occurs, and the thread cache is automatically discarded when a thread exits. However, garbage collection is triggered by allocation activity, so it is possible for a thread that stops allocating/deallocating to retain its cache indefinitely, in which case the developer may find manual flushing useful. thread.prof.name (const char *) r- or -w [] Get/set the descriptive name associated with the calling thread in memory profile dumps. An internal copy of the name string is created, so the input string need not be maintained after this interface completes execution. The output string of this interface should be copied for non-ephemeral uses, because multiple implementation details can cause asynchronous string deallocation. Furthermore, each invocation of this interface can only read or write; simultaneous read/write is not supported due to string lifetime limitations. The name string must be nil-terminated and comprised only of characters in the sets recognized by isgraph 3 and isblank 3. thread.prof.active (bool) rw [] Control whether sampling is currently active for the calling thread. This is an activation mechanism in addition to prof.active; both must be active for the calling thread to sample. This flag is enabled by default. tcache.create (unsigned) r- [] Create an explicit thread-specific cache (tcache) and return an identifier that can be passed to the MALLOCX_TCACHE(tc) macro to explicitly use the specified cache rather than the automatically managed one that is used by default. Each explicit cache can be used by only one thread at a time; the application must assure that this constraint holds. tcache.flush (unsigned) -w [] Flush the specified thread-specific cache (tcache). The same considerations apply to this interface as to thread.tcache.flush, except that the tcache will never be automatically discarded. tcache.destroy (unsigned) -w [] Flush the specified thread-specific cache (tcache) and make the identifier available for use during a future tcache creation. arena.<i>.purge (void) -- Purge all unused dirty pages for arena <i>, or for all arenas if <i> equals arenas.narenas. arena.<i>.decay (void) -- Trigger decay-based purging of unused dirty pages for arena <i>, or for all arenas if <i> equals arenas.narenas. The proportion of unused dirty pages to be purged depends on the current time; see opt.decay_time for details. arena.<i>.reset (void) -- Discard all of the arena's extant allocations. This interface can only be used with arenas created via arenas.extend. None of the arena's discarded/cached allocations may accessed afterward. As part of this requirement, all thread caches which were used to allocate/deallocate in conjunction with the arena must be flushed beforehand. This interface cannot be used if running inside Valgrind, nor if the quarantine size is non-zero. arena.<i>.dss (const char *) rw Set the precedence of dss allocation as related to mmap allocation for arena <i>, or for all arenas if <i> equals arenas.narenas. See opt.dss for supported settings. arena.<i>.lg_dirty_mult (ssize_t) rw Current per-arena minimum ratio (log base 2) of active to dirty pages for arena <i>. Each time this interface is set and the ratio is increased, pages are synchronously purged as necessary to impose the new ratio. See opt.lg_dirty_mult for additional information. arena.<i>.decay_time (ssize_t) rw Current per-arena approximate time in seconds from the creation of a set of unused dirty pages until an equivalent set of unused dirty pages is purged and/or reused. Each time this interface is set, all currently unused dirty pages are considered to have fully decayed, which causes immediate purging of all unused dirty pages unless the decay time is set to -1 (i.e. purging disabled). See opt.decay_time for additional information. arena.<i>.chunk_hooks (chunk_hooks_t) rw Get or set the chunk management hook functions for arena <i>. The functions must be capable of operating on all extant chunks associated with arena <i>, usually by passing unknown chunks to the replaced functions. In practice, it is feasible to control allocation for arenas created via arenas.extend such that all chunks originate from an application-supplied chunk allocator (by setting custom chunk hook functions just after arena creation), but the automatically created arenas may have already created chunks prior to the application having an opportunity to take over chunk allocation. The chunk_hooks_t structure comprises function pointers which are described individually below. jemalloc uses these functions to manage chunk lifetime, which starts off with allocation of mapped committed memory, in the simplest case followed by deallocation. However, there are performance and platform reasons to retain chunks for later reuse. Cleanup attempts cascade from deallocation to decommit to purging, which gives the chunk management functions opportunities to reject the most permanent cleanup operations in favor of less permanent (and often less costly) operations. The chunk splitting and merging operations can also be opted out of, but this is mainly intended to support platforms on which virtual memory mappings provided by the operating system kernel do not automatically coalesce and split, e.g. Windows. typedef void *(chunk_alloc_t) void *chunk size_t size size_t alignment bool *zero bool *commit unsigned arena_ind A chunk allocation function conforms to the chunk_alloc_t type and upon success returns a pointer to size bytes of mapped memory on behalf of arena arena_ind such that the chunk's base address is a multiple of alignment, as well as setting *zero to indicate whether the chunk is zeroed and *commit to indicate whether the chunk is committed. Upon error the function returns NULL and leaves *zero and *commit unmodified. The size parameter is always a multiple of the chunk size. The alignment parameter is always a power of two at least as large as the chunk size. Zeroing is mandatory if *zero is true upon function entry. Committing is mandatory if *commit is true upon function entry. If chunk is not NULL, the returned pointer must be chunk on success or NULL on error. Committed memory may be committed in absolute terms as on a system that does not overcommit, or in implicit terms as on a system that overcommits and satisfies physical memory needs on demand via soft page faults. Note that replacing the default chunk allocation function makes the arena's arena.<i>.dss setting irrelevant. typedef bool (chunk_dalloc_t) void *chunk size_t size bool committed unsigned arena_ind A chunk deallocation function conforms to the chunk_dalloc_t type and deallocates a chunk of given size with committed/decommited memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates opt-out from deallocation; the virtual memory mapping associated with the chunk remains mapped, in the same commit state, and available for future use, in which case it will be automatically retained for later reuse. typedef bool (chunk_commit_t) void *chunk size_t size size_t offset size_t length unsigned arena_ind A chunk commit function conforms to the chunk_commit_t type and commits zeroed physical memory to back pages within a chunk of given size at offset bytes, extending for length on behalf of arena arena_ind, returning false upon success. Committed memory may be committed in absolute terms as on a system that does not overcommit, or in implicit terms as on a system that overcommits and satisfies physical memory needs on demand via soft page faults. If the function returns true, this indicates insufficient physical memory to satisfy the request. typedef bool (chunk_decommit_t) void *chunk size_t size size_t offset size_t length unsigned arena_ind A chunk decommit function conforms to the chunk_decommit_t type and decommits any physical memory that is backing pages within a chunk of given size at offset bytes, extending for length on behalf of arena arena_ind, returning false upon success, in which case the pages will be committed via the chunk commit function before being reused. If the function returns true, this indicates opt-out from decommit; the memory remains committed and available for future use, in which case it will be automatically retained for later reuse. typedef bool (chunk_purge_t) void *chunk size_tsize size_t offset size_t length unsigned arena_ind A chunk purge function conforms to the chunk_purge_t type and optionally discards physical pages within the virtual memory mapping associated with chunk of given size at offset bytes, extending for length on behalf of arena arena_ind, returning false if pages within the purged virtual memory range will be zero-filled the next time they are accessed. typedef bool (chunk_split_t) void *chunk size_t size size_t size_a size_t size_b bool committed unsigned arena_ind A chunk split function conforms to the chunk_split_t type and optionally splits chunk of given size into two adjacent chunks, the first of size_a bytes, and the second of size_b bytes, operating on committed/decommitted memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates that the chunk remains unsplit and therefore should continue to be operated on as a whole. typedef bool (chunk_merge_t) void *chunk_a size_t size_a void *chunk_b size_t size_b bool committed unsigned arena_ind A chunk merge function conforms to the chunk_merge_t type and optionally merges adjacent chunks, chunk_a of given size_a and chunk_b of given size_b into one contiguous chunk, operating on committed/decommitted memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates that the chunks remain distinct mappings and therefore should continue to be operated on independently. arenas.narenas (unsigned) r- Current limit on number of arenas. arenas.initialized (bool *) r- An array of arenas.narenas booleans. Each boolean indicates whether the corresponding arena is initialized. arenas.lg_dirty_mult (ssize_t) rw Current default per-arena minimum ratio (log base 2) of active to dirty pages, used to initialize arena.<i>.lg_dirty_mult during arena creation. See opt.lg_dirty_mult for additional information. arenas.decay_time (ssize_t) rw Current default per-arena approximate time in seconds from the creation of a set of unused dirty pages until an equivalent set of unused dirty pages is purged and/or reused, used to initialize arena.<i>.decay_time during arena creation. See opt.decay_time for additional information. arenas.quantum (size_t) r- Quantum size. arenas.page (size_t) r- Page size. arenas.tcache_max (size_t) r- [] Maximum thread-cached size class. arenas.nbins (unsigned) r- Number of bin size classes. arenas.nhbins (unsigned) r- [] Total number of thread cache bin size classes. arenas.bin.<i>.size (size_t) r- Maximum size supported by size class. arenas.bin.<i>.nregs (uint32_t) r- Number of regions per page run. arenas.bin.<i>.run_size (size_t) r- Number of bytes per page run. arenas.nlruns (unsigned) r- Total number of large size classes. arenas.lrun.<i>.size (size_t) r- Maximum size supported by this large size class. arenas.nhchunks (unsigned) r- Total number of huge size classes. arenas.hchunk.<i>.size (size_t) r- Maximum size supported by this huge size class. arenas.extend (unsigned) r- Extend the array of arenas by appending a new arena, and returning the new arena index. prof.thread_active_init (bool) rw [] Control the initial setting for thread.prof.active in newly created threads. See the opt.prof_thread_active_init option for additional information. prof.active (bool) rw [] Control whether sampling is currently active. See the opt.prof_active option for additional information, as well as the interrelated thread.prof.active mallctl. prof.dump (const char *) -w [] Dump a memory profile to the specified file, or if NULL is specified, to a file according to the pattern <prefix>.<pid>.<seq>.m<mseq>.heap, where <prefix> is controlled by the opt.prof_prefix option. prof.gdump (bool) rw [] When enabled, trigger a memory profile dump every time the total virtual memory exceeds the previous maximum. Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.u<useq>.heap, where <prefix> is controlled by the opt.prof_prefix option. prof.reset (size_t) -w [] Reset all memory profile statistics, and optionally update the sample rate (see opt.lg_prof_sample and prof.lg_sample). prof.lg_sample (size_t) r- [] Get the current sample rate (see opt.lg_prof_sample). prof.interval (uint64_t) r- [] Average number of bytes allocated between interval-based profile dumps. See the opt.lg_prof_interval option for additional information. stats.cactive (size_t *) r- [] Pointer to a counter that contains an approximate count of the current number of bytes in active pages. The estimate may be high, but never low, because each arena rounds up when computing its contribution to the counter. Note that the epoch mallctl has no bearing on this counter. Furthermore, counter consistency is maintained via atomic operations, so it is necessary to use an atomic operation in order to guarantee a consistent read when dereferencing the pointer. stats.allocated (size_t) r- [] Total number of bytes allocated by the application. stats.active (size_t) r- [] Total number of bytes in active pages allocated by the application. This is a multiple of the page size, and greater than or equal to stats.allocated. This does not include stats.arenas.<i>.pdirty, nor pages entirely devoted to allocator metadata. stats.metadata (size_t) r- [] Total number of bytes dedicated to metadata, which comprise base allocations used for bootstrap-sensitive internal allocator data structures, arena chunk headers (see stats.arenas.<i>.metadata.mapped), and internal allocations (see stats.arenas.<i>.metadata.allocated). stats.resident (size_t) r- [] Maximum number of bytes in physically resident data pages mapped by the allocator, comprising all pages dedicated to allocator metadata, pages backing active allocations, and unused dirty pages. This is a maximum rather than precise because pages may not actually be physically resident if they correspond to demand-zeroed virtual memory that has not yet been touched. This is a multiple of the page size, and is larger than stats.active. stats.mapped (size_t) r- [] Total number of bytes in active chunks mapped by the allocator. This is a multiple of the chunk size, and is larger than stats.active. This does not include inactive chunks, even those that contain unused dirty pages, which means that there is no strict ordering between this and stats.resident. stats.retained (size_t) r- [] Total number of bytes in virtual memory mappings that were retained rather than being returned to the operating system via e.g. munmap 2. Retained virtual memory is typically untouched, decommitted, or purged, so it has no strongly associated physical memory (see chunk hooks for details). Retained memory is excluded from mapped memory statistics, e.g. stats.mapped. stats.arenas.<i>.dss (const char *) r- dss (sbrk 2) allocation precedence as related to mmap 2 allocation. See opt.dss for details. stats.arenas.<i>.lg_dirty_mult (ssize_t) r- Minimum ratio (log base 2) of active to dirty pages. See opt.lg_dirty_mult for details. stats.arenas.<i>.decay_time (ssize_t) r- Approximate time in seconds from the creation of a set of unused dirty pages until an equivalent set of unused dirty pages is purged and/or reused. See opt.decay_time for details. stats.arenas.<i>.nthreads (unsigned) r- Number of threads currently assigned to arena. stats.arenas.<i>.pactive (size_t) r- Number of pages in active runs. stats.arenas.<i>.pdirty (size_t) r- Number of pages within unused runs that are potentially dirty, and for which madvise... MADV_DONTNEED or similar has not been called. stats.arenas.<i>.mapped (size_t) r- [] Number of mapped bytes. stats.arenas.<i>.retained (size_t) r- [] Number of retained bytes. See stats.retained for details. stats.arenas.<i>.metadata.mapped (size_t) r- [] Number of mapped bytes in arena chunk headers, which track the states of the non-metadata pages. stats.arenas.<i>.metadata.allocated (size_t) r- [] Number of bytes dedicated to internal allocations. Internal allocations differ from application-originated allocations in that they are for internal use, and that they are omitted from heap profiles. This statistic is reported separately from stats.metadata and stats.arenas.<i>.metadata.mapped because it overlaps with e.g. the stats.allocated and stats.active statistics, whereas the other metadata statistics do not. stats.arenas.<i>.npurge (uint64_t) r- [] Number of dirty page purge sweeps performed. stats.arenas.<i>.nmadvise (uint64_t) r- [] Number of madvise... MADV_DONTNEED or similar calls made to purge dirty pages. stats.arenas.<i>.purged (uint64_t) r- [] Number of pages purged. stats.arenas.<i>.small.allocated (size_t) r- [] Number of bytes currently allocated by small objects. stats.arenas.<i>.small.nmalloc (uint64_t) r- [] Cumulative number of allocation requests served by small bins. stats.arenas.<i>.small.ndalloc (uint64_t) r- [] Cumulative number of small objects returned to bins. stats.arenas.<i>.small.nrequests (uint64_t) r- [] Cumulative number of small allocation requests. stats.arenas.<i>.large.allocated (size_t) r- [] Number of bytes currently allocated by large objects. stats.arenas.<i>.large.nmalloc (uint64_t) r- [] Cumulative number of large allocation requests served directly by the arena. stats.arenas.<i>.large.ndalloc (uint64_t) r- [] Cumulative number of large deallocation requests served directly by the arena. stats.arenas.<i>.large.nrequests (uint64_t) r- [] Cumulative number of large allocation requests. stats.arenas.<i>.huge.allocated (size_t) r- [] Number of bytes currently allocated by huge objects. stats.arenas.<i>.huge.nmalloc (uint64_t) r- [] Cumulative number of huge allocation requests served directly by the arena. stats.arenas.<i>.huge.ndalloc (uint64_t) r- [] Cumulative number of huge deallocation requests served directly by the arena. stats.arenas.<i>.huge.nrequests (uint64_t) r- [] Cumulative number of huge allocation requests. stats.arenas.<i>.bins.<j>.nmalloc (uint64_t) r- [] Cumulative number of allocations served by bin. stats.arenas.<i>.bins.<j>.ndalloc (uint64_t) r- [] Cumulative number of allocations returned to bin. stats.arenas.<i>.bins.<j>.nrequests (uint64_t) r- [] Cumulative number of allocation requests. stats.arenas.<i>.bins.<j>.curregs (size_t) r- [] Current number of regions for this size class. stats.arenas.<i>.bins.<j>.nfills (uint64_t) r- [ ] Cumulative number of tcache fills. stats.arenas.<i>.bins.<j>.nflushes (uint64_t) r- [ ] Cumulative number of tcache flushes. stats.arenas.<i>.bins.<j>.nruns (uint64_t) r- [] Cumulative number of runs created. stats.arenas.<i>.bins.<j>.nreruns (uint64_t) r- [] Cumulative number of times the current run from which to allocate changed. stats.arenas.<i>.bins.<j>.curruns (size_t) r- [] Current number of runs. stats.arenas.<i>.lruns.<j>.nmalloc (uint64_t) r- [] Cumulative number of allocation requests for this size class served directly by the arena. stats.arenas.<i>.lruns.<j>.ndalloc (uint64_t) r- [] Cumulative number of deallocation requests for this size class served directly by the arena. stats.arenas.<i>.lruns.<j>.nrequests (uint64_t) r- [] Cumulative number of allocation requests for this size class. stats.arenas.<i>.lruns.<j>.curruns (size_t) r- [] Current number of runs for this size class. stats.arenas.<i>.hchunks.<j>.nmalloc (uint64_t) r- [] Cumulative number of allocation requests for this size class served directly by the arena. stats.arenas.<i>.hchunks.<j>.ndalloc (uint64_t) r- [] Cumulative number of deallocation requests for this size class served directly by the arena. stats.arenas.<i>.hchunks.<j>.nrequests (uint64_t) r- [] Cumulative number of allocation requests for this size class. stats.arenas.<i>.hchunks.<j>.curhchunks (size_t) r- [] Current number of huge allocations for this size class. HEAP PROFILE FORMAT Although the heap profiling functionality was originally designed to be compatible with the pprof command that is developed as part of the gperftools package, the addition of per thread heap profiling functionality required a different heap profile format. The jeprof command is derived from pprof, with enhancements to support the heap profile format described here. In the following hypothetical heap profile, [...] indicates elision for the sake of compactness. The following matches the above heap profile, but most tokens are replaced with <description> to indicate descriptions of the corresponding fields. / : : [: ] [...] : : [: ] [...] : : [: ] [...] @ [...] [...] : : [: ] : : [: ] : : [: ] [...] MAPPED_LIBRARIES: /maps>]]> DEBUGGING MALLOC PROBLEMS When debugging, it is a good idea to configure/build jemalloc with the and options, and recompile the program with suitable options and symbols for debugger support. When so configured, jemalloc incorporates a wide variety of run-time assertions that catch application errors such as double-free, write-after-free, etc. Programs often accidentally depend on “uninitialized” memory actually being filled with zero bytes. Junk filling (see the opt.junk option) tends to expose such bugs in the form of obviously incorrect results and/or coredumps. Conversely, zero filling (see the opt.zero option) eliminates the symptoms of such bugs. Between these two options, it is usually possible to quickly detect, diagnose, and eliminate such bugs. This implementation does not provide much detail about the problems it detects, because the performance impact for storing such information would be prohibitive. However, jemalloc does integrate with the most excellent Valgrind tool if the configuration option is enabled. DIAGNOSTIC MESSAGES If any of the memory allocation/deallocation functions detect an error or warning condition, a message will be printed to file descriptor STDERR_FILENO. Errors will result in the process dumping core. If the opt.abort option is set, most warnings are treated as errors. The malloc_message variable allows the programmer to override the function which emits the text strings forming the errors and warnings if for some reason the STDERR_FILENO file descriptor is not suitable for this. malloc_message takes the cbopaque pointer argument that is NULL unless overridden by the arguments in a call to malloc_stats_print, followed by a string pointer. Please note that doing anything which tries to allocate memory in this function is likely to result in a crash or deadlock. All messages are prefixed by “<jemalloc>: ”. RETURN VALUES Standard API The malloc and calloc functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set to ENOMEM. The posix_memalign function returns the value 0 if successful; otherwise it returns an error value. The posix_memalign function will fail if: EINVAL The alignment parameter is not a power of 2 at least as large as sizeof(void *). ENOMEM Memory allocation error. The aligned_alloc function returns a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set. The aligned_alloc function will fail if: EINVAL The alignment parameter is not a power of 2. ENOMEM Memory allocation error. The realloc function returns a pointer, possibly identical to ptr, to the allocated memory if successful; otherwise a NULL pointer is returned, and errno is set to ENOMEM if the error was the result of an allocation failure. The realloc function always leaves the original buffer intact when an error occurs. The free function returns no value. Non-standard API The mallocx and rallocx functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned to indicate insufficient contiguous memory was available to service the allocation request. The xallocx function returns the real size of the resulting resized allocation pointed to by ptr, which is a value less than size if the allocation could not be adequately grown in place. The sallocx function returns the real size of the allocation pointed to by ptr. The nallocx returns the real size that would result from a successful equivalent mallocx function call, or zero if insufficient memory is available to perform the size computation. The mallctl, mallctlnametomib, and mallctlbymib functions return 0 on success; otherwise they return an error value. The functions will fail if: EINVAL newp is not NULL, and newlen is too large or too small. Alternatively, *oldlenp is too large or too small; in this case as much data as possible are read despite the error. ENOENT name or mib specifies an unknown/invalid value. EPERM Attempt to read or write void value, or attempt to write read-only value. EAGAIN A memory allocation failure occurred. EFAULT An interface with side effects failed in some way not directly related to mallctl* read/write processing. The malloc_usable_size function returns the usable size of the allocation pointed to by ptr. ENVIRONMENT The following environment variable affects the execution of the allocation functions: MALLOC_CONF If the environment variable MALLOC_CONF is set, the characters it contains will be interpreted as options.

Line editing with some support for history is a really important feature for command line utilities. Instead of retyping almost the same stuff again and again it's just much better to hit the up arrow and edit on syntax errors, or in order to try a slightly different command. But apparently code dealing with terminals is some sort of Black Magic: readline is 30k lines of code, libedit 20k. Is it reasonable to link small utilities to huge libraries just to get a minimal support for line editing? So what usually happens is either: * Large programs with configure scripts disabling line editing if readline is not present in the system, or not supporting it at all since readline is GPL licensed and libedit (the BSD clone) is not as known and available as readline is (Real world example of this problem: Tclsh). * Smaller programs not using a configure script not supporting line editing at all (A problem we had with Redis-cli for instance). The result is a pollution of binaries without line editing support. So I spent more or less two hours doing a reality check resulting in this little library: is it *really* needed for a line editing library to be 20k lines of code? Apparently not, it is possibe to get a very small, zero configuration, trivial to embed library, that solves the problem. Smaller programs will just include this, supporing line editing out of the box. Larger programs may use this little library or just checking with configure if readline/libedit is available and resorting to Linenoise if not. ## Terminals, in 2010. Apparently almost every terminal you can happen to use today has some kind of support for basic VT100 escape sequences. So I tried to write a lib using just very basic VT100 features. The resulting library appears to work everywhere I tried to use it, and now can work even on ANSI.SYS compatible terminals, since no VT220 specific sequences are used anymore. The library is currently about 1100 lines of code. In order to use it in your project just look at the *example.c* file in the source distribution, it is trivial. Linenoise is BSD code, so you can use both in free software and commercial software. ## Tested with... * Linux text only console ($TERM = linux) * Linux KDE terminal application ($TERM = xterm) * Linux xterm ($TERM = xterm) * Linux Buildroot ($TERM = vt100) * Mac OS X iTerm ($TERM = xterm) * Mac OS X default Terminal.app ($TERM = xterm) * OpenBSD 4.5 through an OSX Terminal.app ($TERM = screen) * IBM AIX 6.1 * FreeBSD xterm ($TERM = xterm) * ANSI.SYS * Emacs comint mode ($TERM = dumb) Please test it everywhere you can and report back! ## Let's push this forward! Patches should be provided in the respect of Linenoise sensibility for small easy to understand code. Send feedbacks to antirez at gmail # The API Linenoise is very easy to use, and reading the example shipped with the library should get you up to speed ASAP. Here is a list of API calls and how to use them. char *linenoise(const char *prompt); This is the main Linenoise call: it shows the user a prompt with line editing and history capabilities. The prompt you specify is used as a prompt, that is, it will be printed to the left of the cursor. The library returns a buffer with the line composed by the user, or NULL on end of file or when there is an out of memory condition. When a tty is detected (the user is actually typing into a terminal session) the maximum editable line length is `LINENOISE_MAX_LINE`. When instead the standard input is not a tty, which happens every time you redirect a file to a program, or use it in an Unix pipeline, there are no limits to the length of the line that can be returned. The returned line should be freed with the `free()` standard system call. However sometimes it could happen that your program uses a different dynamic allocation library, so you may also used `linenoiseFree` to make sure the line is freed with the same allocator it was created. The canonical loop used by a program using Linenoise will be something like this: while((line = linenoise("hello> ")) != NULL) { printf("You wrote: %s\n", line); linenoiseFree(line); /* Or just free(line) if you use libc malloc. */ } ## Single line VS multi line editing By default, Linenoise uses single line editing, that is, a single row on the screen will be used, and as the user types more, the text will scroll towards left to make room. This works if your program is one where the user is unlikely to write a lot of text, otherwise multi line editing, where multiple screens rows are used, can be a lot more comfortable. In order to enable multi line editing use the following API call: linenoiseSetMultiLine(1); You can disable it using `0` as argument. ## History Linenoise supporst history, so that the user does not have to retype again and again the same things, but can use the down and up arrows in order to search and re-edit already inserted lines of text. The followings are the history API calls: int linenoiseHistoryAdd(const char *line); int linenoiseHistorySetMaxLen(int len); int linenoiseHistorySave(const char *filename); int linenoiseHistoryLoad(const char *filename); Use `linenoiseHistoryAdd` every time you want to add a new element to the top of the history (it will be the first the user will see when using the up arrow). Note that for history to work, you have to set a length for the history (which is zero by default, so history will be disabled if you don't set a proper one). This is accomplished using the `linenoiseHistorySetMaxLen` function. Linenoise has direct support for persisting the history into an history file. The functions `linenoiseHistorySave` and `linenoiseHistoryLoad` do just that. Both functions return -1 on error and 0 on success. ## Completion Linenoise supports completion, which is the ability to complete the user input when she or he presses the `` key. In order to use completion, you need to register a completion callback, which is called every time the user presses ``. Your callback will return a list of items that are completions for the current string. The following is an example of registering a completion callback: linenoiseSetCompletionCallback(completion); The completion must be a function returning `void` and getting as input a `const char` pointer, which is the line the user has typed so far, and a `linenoiseCompletions` object pointer, which is used as argument of `linenoiseAddCompletion` in order to add completions inside the callback. An example will make it more clear: void completion(const char *buf, linenoiseCompletions *lc) { if (buf[0] == 'h') { linenoiseAddCompletion(lc,"hello"); linenoiseAddCompletion(lc,"hello there"); } } Basically in your completion callback, you inspect the input, and return a list of items that are good completions by using `linenoiseAddCompletion`. If you want to test the completion feature, compile the example program with `make`, run it, type `h` and press ``. ## Hints Linenoise has a feature called *hints* which is very useful when you use Linenoise in order to implement a REPL (Read Eval Print Loop) for a program that accepts commands and arguments, but may also be useful in other conditions. The feature shows, on the right of the cursor, as the user types, hints that may be useful. The hints can be displayed using a different color compared to the color the user is typing, and can also be bold. For example as the user starts to type `"git remote add"`, with hints it's possible to show on the right of the prompt a string ` `. The feature works similarly to the history feature, using a callback. To register the callback we use: linenoiseSetHintsCallback(hints); The callback itself is implemented like this: char *hints(const char *buf, int *color, int *bold) { if (!strcasecmp(buf,"git remote add")) { *color = 35; *bold = 0; return " "; } return NULL; } The callback function returns the string that should be displayed or NULL if no hint is available for the text the user currently typed. The returned string will be trimmed as needed depending on the number of columns available on the screen. It is possible to return a string allocated in dynamic way, by also registering a function to deallocate the hint string once used: void linenoiseSetFreeHintsCallback(linenoiseFreeHintsCallback *); The free hint callback will just receive the pointer and free the string as needed (depending on how the hits callback allocated it). As you can see in the example above, a `color` (in xterm color terminal codes) can be provided together with a `bold` attribute. If no color is set, the current terminal foreground color is used. If no bold attribute is set, non-bold text is printed. Color codes are: red = 31 green = 32 yellow = 33 blue = 34 magenta = 35 cyan = 36 white = 37; ## Screen handling Sometimes you may want to clear the screen as a result of something the user typed. You can do this by calling the following function: void linenoiseClearScreen(void); ================================================ FILE: extern/deprecated/redis-3.2.4/deps/linenoise/example.c ================================================ #include #include #include #include "linenoise.h" void completion(const char *buf, linenoiseCompletions *lc) { if (buf[0] == 'h') { linenoiseAddCompletion(lc,"hello"); linenoiseAddCompletion(lc,"hello there"); } } char *hints(const char *buf, int *color, int *bold) { if (!strcasecmp(buf,"hello")) { *color = 35; *bold = 0; return " World"; } return NULL; } int main(int argc, char **argv) { char *line; char *prgname = argv[0]; /* Parse options, with --multiline we enable multi line editing. */ while(argc > 1) { argc--; argv++; if (!strcmp(*argv,"--multiline")) { linenoiseSetMultiLine(1); printf("Multi-line mode enabled.\n"); } else if (!strcmp(*argv,"--keycodes")) { linenoisePrintKeyCodes(); exit(0); } else { fprintf(stderr, "Usage: %s [--multiline] [--keycodes]\n", prgname); exit(1); } } /* Set the completion callback.

API: + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer. + introduced lightweight userdata, a simple "void*" without a metatable. + new error handling protocol: the core no longer prints error messages; all errors are reported to the caller on the stack. + new lua_atpanic for host cleanup. + new, signal-safe, hook scheme. Implementation: + new license: MIT. + new, faster, register-based virtual machine. + support for external multithreading and coroutines. + new and consistent error message format. + the core no longer needs "stdio.h" for anything (except for a single use of sprintf to convert numbers to strings). + lua.c now runs the environment variable LUA_INIT, if present. It can be "@filename", to run a file, or the chunk itself. + support for user extensions in lua.c. sample implementation given for command line editing. + new dynamic loading library, active by default on several platforms. + safe garbage-collector metamethods. + precompiled bytecodes checked for integrity (secure binary dostring). + strings are fully aligned. + position capture in string.find. + read('*l') can read lines with embedded zeros. * Changes from version 3.2 to 4.0 ------------------------------- Language: + new "break" and "for" statements (both numerical and for tables). + uniform treatment of globals: globals are now stored in a Lua table. + improved error messages. + no more '$debug': full speed *and* full debug information. + new read form: read(N) for next N bytes. + general read patterns now deprecated. (still available with -DCOMPAT_READPATTERNS.) + all return values are passed as arguments for the last function (old semantics still available with -DLUA_COMPAT_ARGRET) + garbage collection tag methods for tables now deprecated. + there is now only one tag method for order. API: + New API: fully re-entrant, simpler, and more efficient. + New debug API. Implementation: + faster than ever: cleaner virtual machine and new hashing algorithm. + non-recursive garbage-collector algorithm. + reduced memory usage for programs with many strings. + improved treatment for memory allocation errors. + improved support for 16-bit machines (we hope). + code now compiles unmodified as both ANSI C and C++. + numbers in bases other than 10 are converted using strtoul. + new -f option in Lua to support #! scripts. + luac can now combine text and binaries. * Changes from version 3.1 to 3.2 ------------------------------- + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT. + increased limit on the number of constants and globals per function (from 2^16 to 2^24). + debugging info (lua_debug and hooks) moved into lua_state and new API functions provided to get and set this info. + new debug lib gives full debugging access within Lua. + new table functions "foreachi", "sort", "tinsert", "tremove", "getn". + new io functions "flush", "seek". * Changes from version 3.0 to 3.1 ------------------------------- + NEW FEATURE: anonymous functions with closures (via "upvalues"). + new syntax: - local variables in chunks. - better scope control with DO block END. - constructors can now be also written: { record-part; list-part }. - more general syntax for function calls and lvalues, e.g.: f(x).y=1 o:f(x,y):g(z) f"string" is sugar for f("string") + strings may now contain arbitrary binary data (e.g., embedded zeros). + major code re-organization and clean-up; reduced module interdependecies. + no arbitrary limits on the total number of constants and globals. + support for multiple global contexts. + better syntax error messages. + new traversal functions "foreach" and "foreachvar". + the default for numbers is now double. changing it to use floats or longs is easy. + complete debug information stored in pre-compiled chunks. + sample interpreter now prompts user when run interactively, and also handles control-C interruptions gracefully. * Changes from version 2.5 to 3.0 ------------------------------- + NEW CONCEPT: "tag methods". Tag methods replace fallbacks as the meta-mechanism for extending the semantics of Lua. Whereas fallbacks had a global nature, tag methods work on objects having the same tag (e.g., groups of tables). Existing code that uses fallbacks should work without change. + new, general syntax for constructors {[exp] = exp, ... }. + support for handling variable number of arguments in functions (varargs). + support for conditional compilation ($if ... $else ... $end). + cleaner semantics in API simplifies host code. + better support for writing libraries (auxlib.h). + better type checking and error messages in the standard library. + luac can now also undump. * Changes from version 2.4 to 2.5 ------------------------------- + io and string libraries are now based on pattern matching; the old libraries are still available for compatibility + dofile and dostring can now return values (via return statement) + better support for 16- and 64-bit machines + expanded documentation, with more examples * Changes from version 2.2 to 2.4 ------------------------------- + external compiler creates portable binary files that can be loaded faster + interface for debugging and profiling + new "getglobal" fallback + new functions for handling references to Lua objects + new functions in standard lib + only one copy of each string is stored + expanded documentation, with more examples * Changes from version 2.1 to 2.2 ------------------------------- + functions now may be declared with any "lvalue" as a name + garbage collection of functions + support for pipes * Changes from version 1.1 to 2.1 ------------------------------- + object-oriented support + fallbacks + simplified syntax for tables + many internal improvements (end of HISTORY) ================================================ FILE: extern/deprecated/redis-3.2.4/deps/lua/INSTALL ================================================ INSTALL for Lua 5.1 * Building Lua ------------ Lua is built in the src directory, but the build process can be controlled from the top-level Makefile. Building Lua on Unix systems should be very easy. First do "make" and see if your platform is listed. If so, just do "make xxx", where xxx is your platform name. The platforms currently supported are: aix ansi bsd freebsd generic linux macosx mingw posix solaris If your platform is not listed, try the closest one or posix, generic, ansi, in this order. See below for customization instructions and for instructions on how to build with other Windows compilers. If you want to check that Lua has been built correctly, do "make test" after building Lua. Also, have a look at the example programs in test. * Installing Lua -------------- Once you have built Lua, you may want to install it in an official place in your system. In this case, do "make install". The official place and the way to install files are defined in Makefile. You must have the right permissions to install files. If you want to build and install Lua in one step, do "make xxx install", where xxx is your platform name. If you want to install Lua locally, then do "make local". This will create directories bin, include, lib, man, and install Lua there as follows: bin: lua luac include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp lib: liblua.a man/man1: lua.1 luac.1 These are the only directories you need for development. There are man pages for lua and luac, in both nroff and html, and a reference manual in html in doc, some sample code in test, and some useful stuff in etc. You don't need these directories for development. If you want to install Lua locally, but in some other directory, do "make install INSTALL_TOP=xxx", where xxx is your chosen directory. See below for instructions for Windows and other systems. * Customization ------------- Three things can be customized by editing a file: - Where and how to install Lua -- edit Makefile. - How to build Lua -- edit src/Makefile. - Lua features -- edit src/luaconf.h. You don't actually need to edit the Makefiles because you may set the relevant variables when invoking make. On the other hand, if you need to select some Lua features, you'll need to edit src/luaconf.h. The edited file will be the one installed, and it will be used by any Lua clients that you build, to ensure consistency. We strongly recommend that you enable dynamic loading. This is done automatically for all platforms listed above that have this feature (and also Windows). See src/luaconf.h and also src/Makefile. * Building Lua on Windows and other systems ----------------------------------------- If you're not using the usual Unix tools, then the instructions for building Lua depend on the compiler you use. You'll need to create projects (or whatever your compiler uses) for building the library, the interpreter, and the compiler, as follows: library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c ltm.c lundump.c lvm.c lzio.c lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c ltablib.c lstrlib.c loadlib.c linit.c interpreter: library, lua.c compiler: library, luac.c print.c If you use Visual Studio .NET, you can use etc/luavs.bat in its "Command Prompt". If all you want is to build the Lua interpreter, you may put all .c files in a single project, except for luac.c and print.c. Or just use etc/all.c. To use Lua as a library in your own programs, you'll need to know how to create and use libraries with your compiler. As mentioned above, you may edit luaconf.h to select some features before building Lua.

The given .I args are available to .I script as strings in a global table named .BR arg . If these arguments contain spaces or other characters special to the shell, then they should be quoted (but note that the quotes will be removed by the shell). The arguments in .B arg start at 0, which contains the string .RI ' script '. The index of the last argument is stored in .BR arg.n . The arguments given in the command line before .IR script , including the name of the interpreter, are available in negative indices in .BR arg . .LP At the very start, before even handling the command line, .B lua executes the contents of the environment variable .BR LUA_INIT , if it is defined. If the value of .B LUA_INIT is of the form .RI '@ filename ', then .I filename is executed. Otherwise, the string is assumed to be a Lua statement and is executed. .LP Options start with .B '\-' and are described below. You can use .B "'\--'" to signal the end of options. .LP If no arguments are given, then .B "\-v \-i" is assumed when the standard input is a terminal; otherwise, .B "\-" is assumed. .LP In interactive mode, .B lua prompts the user, reads lines from the standard input, and executes them as they are read. If a line does not contain a complete statement, then a secondary prompt is displayed and lines are read until a complete statement is formed or a syntax error is found. So, one way to interrupt the reading of an incomplete statement is to force a syntax error: adding a .B ';' in the middle of a statement is a sure way of forcing a syntax error (except inside multiline strings and comments; these must be closed explicitly). If a line starts with .BR '=' , then .B lua displays the values of all the expressions in the remainder of the line. The expressions must be separated by commas. The primary prompt is the value of the global variable .BR _PROMPT , if this value is a string; otherwise, the default prompt is used. Similarly, the secondary prompt is the value of the global variable .BR _PROMPT2 . So, to change the prompts, set the corresponding variable to a string of your choice. You can do that after calling the interpreter or on the command line (but in this case you have to be careful with quotes if the prompt string contains a space; otherwise you may confuse the shell.) The default prompts are "> " and ">> ". .SH OPTIONS .TP .B \- load and execute the standard input as a file, that is, not interactively, even when the standard input is a terminal. .TP .BI \-e " stat" execute statement .IR stat .

NAME

lua - Lua interpreter

SYNOPSIS

lua [ options ] [ script [ args ] ]

DESCRIPTION

lua is the stand-alone Lua interpreter. It loads and executes Lua programs, either in textual source form or in precompiled binary form. (Precompiled binaries are output by luac, the Lua compiler.) lua can be used as a batch interpreter and also interactively.

The given options (see below) are executed and then the Lua program in file script is loaded and executed. The given args are available to script as strings in a global table named arg. If these arguments contain spaces or other characters special to the shell, then they should be quoted (but note that the quotes will be removed by the shell). The arguments in arg start at 0, which contains the string 'script'. The index of the last argument is stored in arg.n. The arguments given in the command line before script, including the name of the interpreter, are available in negative indices in arg.

At the very start, before even handling the command line, lua executes the contents of the environment variable LUA_INIT, if it is defined. If the value of LUA_INIT is of the form '@filename', then filename is executed. Otherwise, the string is assumed to be a Lua statement and is executed.

Options start with '-' and are described below. You can use '--' to signal the end of options.

If no arguments are given, then "-v -i" is assumed when the standard input is a terminal; otherwise, "-" is assumed.

In interactive mode, lua prompts the user, reads lines from the standard input, and executes them as they are read. If a line does not contain a complete statement, then a secondary prompt is displayed and lines are read until a complete statement is formed or a syntax error is found. So, one way to interrupt the reading of an incomplete statement is to force a syntax error: adding a ';' in the middle of a statement is a sure way of forcing a syntax error (except inside multiline strings and comments; these must be closed explicitly). If a line starts with '=', then lua displays the values of all the expressions in the remainder of the line. The expressions must be separated by commas. The primary prompt is the value of the global variable _PROMPT, if this value is a string; otherwise, the default prompt is used. Similarly, the secondary prompt is the value of the global variable _PROMPT2. So, to change the prompts, set the corresponding variable to a string of your choice. You can do that after calling the interpreter or on the command line (but in this case you have to be careful with quotes if the prompt string contains a space; otherwise you may confuse the shell.) The default prompts are "> " and ">> ".

OPTIONS

- load and execute the standard input as a file, that is, not interactively, even when the standard input is a terminal.

-e stat execute statement stat. You need to quote stat if it contains spaces, quotes, or other characters special to the shell.

-i enter interactive mode after script is executed.

-l name call require('name') before executing script. Typically used to load libraries.

-v show version information.

NAME

luac - Lua compiler

SYNOPSIS

luac [ options ] [ filenames ]

DESCRIPTION

luac is the Lua compiler. It translates programs written in the Lua programming language into binary files that can be later loaded and executed.

The main advantages of precompiling chunks are: faster loading, protecting source code from accidental user changes, and off-line syntax checking.

Precompiling does not imply faster execution because in Lua chunks are always compiled into bytecodes before being executed. luac simply allows those bytecodes to be saved in a file for later execution.

Precompiled chunks are not necessarily smaller than the corresponding source. The main goal in precompiling is faster loading.

The binary files created by luac are portable only among architectures with the same word size and byte order.

luac produces a single output file containing the bytecodes for all source files given. By default, the output file is named luac.out, but you can change this with the -o option.

In the command line, you can mix text files containing Lua source and binary files containing precompiled chunks. This is useful because several precompiled chunks, even from different (but compatible) platforms, can be combined into a single precompiled chunk.

You can use '-' to indicate the standard input as a source file and '--' to signal the end of options (that is, all remaining arguments will be treated as files even if they start with '-').

The internal format of the binary files produced by luac is likely to change when a new version of Lua is released. So, save the source files of all Lua programs that you precompile.

OPTIONS

Options must be separate.

-l produce a listing of the compiled bytecode for Lua's virtual machine. Listing bytecodes is useful to learn about Lua's virtual machine. If no files are given, then luac loads luac.out and lists its contents.

-o file output to file, instead of the default luac.out. (You can use '-' for standard output, but not on platforms that open standard output in text mode.) The output file may be a source file because all files are loaded before the output file is written. Be careful not to overwrite precious files.

-p load files but do not generate any output file. Used mainly for syntax checking and for testing precompiled chunks: corrupted files will probably generate errors when loaded. Lua always performs a thorough integrity test on precompiled chunks. Bytecode that passes this test is completely safe, in the sense that it will not break the interpreter. However, there is no guarantee that such code does anything sensible. (None can be given, because the halting problem is unsolvable.) If no files are given, then luac loads luac.out and tests its contents. No messages are displayed if the file passes the integrity test.

-s strip debug information before writing the output file. This saves some space in very large chunks, but if errors occur when running a stripped chunk, then the error messages may not contain the full information they usually do. For instance, line numbers and names of local variables are lost.

-v show version information.

1 - Introduction

Lua is an extension programming language designed to support general procedural programming with data description facilities. It also offers good support for object-oriented programming, functional programming, and data-driven programming. Lua is intended to be used as a powerful, light-weight scripting language for any program that needs one. Lua is implemented as a library, written in clean C (that is, in the common subset of ANSI C and C++).

Being an extension language, Lua has no notion of a "main" program: it only works embedded in a host client, called the embedding program or simply the host. This host program can invoke functions to execute a piece of Lua code, can write and read Lua variables, and can register C functions to be called by Lua code. Through the use of C functions, Lua can be augmented to cope with a wide range of different domains, thus creating customized programming languages sharing a syntactical framework. The Lua distribution includes a sample host program called lua, which uses the Lua library to offer a complete, stand-alone Lua interpreter.

Lua is free software, and is provided as usual with no guarantees, as stated in its license. The implementation described in this manual is available at Lua's official web site, www.lua.org.

Like any other reference manual, this document is dry in places. For a discussion of the decisions behind the design of Lua, see the technical papers available at Lua's web site. For a detailed introduction to programming in Lua, see Roberto's book, Programming in Lua (Second Edition).

2 - The Language

This section describes the lexis, the syntax, and the semantics of Lua. In other words, this section describes which tokens are valid, how they can be combined, and what their combinations mean.

The language constructs will be explained using the usual extended BNF notation, in which {a} means 0 or more a's, and [a] means an optional a. Non-terminals are shown like non-terminal, keywords are shown like kword, and other terminal symbols are shown like `=´. The complete syntax of Lua can be found in §8 at the end of this manual.

2.1 - Lexical Conventions

Names (also called identifiers) in Lua can be any string of letters, digits, and underscores, not beginning with a digit. This coincides with the definition of names in most languages. (The definition of letter depends on the current locale: any character considered alphabetic by the current locale can be used in an identifier.) Identifiers are used to name variables and table fields.

The following keywords are reserved and cannot be used as names: 

     and       break     do        else      elseif
     end       false     for       function  if
     in        local     nil       not       or
     repeat    return    then      true      until     while

Lua is a case-sensitive language: and is a reserved word, but And and AND are two different, valid names. As a convention, names starting with an underscore followed by uppercase letters (such as _VERSION) are reserved for internal global variables used by Lua.

The following strings denote other tokens: 

     +     -     *     /     %     ^     #
     ==    ~=    <=    >=    <     >     =
     (     )     {     }     [     ]
     ;     :     ,     .     ..    ...

Literal strings can be delimited by matching single or double quotes, and can contain the following C-like escape sequences: '\a' (bell), '\b' (backspace), '\f' (form feed), '\n' (newline), '\r' (carriage return), '\t' (horizontal tab), '\v' (vertical tab), '\\' (backslash), '\"' (quotation mark [double quote]), and '\'' (apostrophe [single quote]). Moreover, a backslash followed by a real newline results in a newline in the string. A character in a string can also be specified by its numerical value using the escape sequence \ddd, where ddd is a sequence of up to three decimal digits. (Note that if a numerical escape is to be followed by a digit, it must be expressed using exactly three digits.) Strings in Lua can contain any 8-bit value, including embedded zeros, which can be specified as '\0'.

Literal strings can also be defined using a long format enclosed by long brackets. We define an opening long bracket of level n as an opening square bracket followed by n equal signs followed by another opening square bracket. So, an opening long bracket of level 0 is written as [[, an opening long bracket of level 1 is written as [=[, and so on. A closing long bracket is defined similarly; for instance, a closing long bracket of level 4 is written as ]====]. A long string starts with an opening long bracket of any level and ends at the first closing long bracket of the same level. Literals in this bracketed form can run for several lines, do not interpret any escape sequences, and ignore long brackets of any other level. They can contain anything except a closing bracket of the proper level.

For convenience, when the opening long bracket is immediately followed by a newline, the newline is not included in the string. As an example, in a system using ASCII (in which 'a' is coded as 97, newline is coded as 10, and '1' is coded as 49), the five literal strings below denote the same string: 

     a = 'alo\n123"'
     a = "alo\n123\""
     a = '\97lo\10\04923"'
     a = [[alo
     123"]]
     a = [==[
     alo
     123"]==]

A numerical constant can be written with an optional decimal part and an optional decimal exponent. Lua also accepts integer hexadecimal constants, by prefixing them with 0x. Examples of valid numerical constants are 

     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56

A comment starts with a double hyphen (--) anywhere outside a string. If the text immediately after -- is not an opening long bracket, the comment is a short comment, which runs until the end of the line. Otherwise, it is a long comment, which runs until the corresponding closing long bracket. Long comments are frequently used to disable code temporarily.

2.2 - Values and Types

Lua is a dynamically typed language. This means that variables do not have types; only values do. There are no type definitions in the language. All values carry their own type.

All values in Lua are first-class values. This means that all values can be stored in variables, passed as arguments to other functions, and returned as results.

There are eight basic types in Lua: nil, boolean, number, string, function, userdata, thread, and table. Nil is the type of the value nil, whose main property is to be different from any other value; it usually represents the absence of a useful value. Boolean is the type of the values false and true. Both nil and false make a condition false; any other value makes it true. Number represents real (double-precision floating-point) numbers. (It is easy to build Lua interpreters that use other internal representations for numbers, such as single-precision float or long integers; see file luaconf.h.) String represents arrays of characters. Lua is 8-bit clean: strings can contain any 8-bit character, including embedded zeros ('\0') (see §2.1).

Lua can call (and manipulate) functions written in Lua and functions written in C (see §2.5.8).

The type userdata is provided to allow arbitrary C data to be stored in Lua variables. This type corresponds to a block of raw memory and has no pre-defined operations in Lua, except assignment and identity test. However, by using metatables, the programmer can define operations for userdata values (see §2.8). Userdata values cannot be created or modified in Lua, only through the C API. This guarantees the integrity of data owned by the host program.

The type thread represents independent threads of execution and it is used to implement coroutines (see §2.11). Do not confuse Lua threads with operating-system threads. Lua supports coroutines on all systems, even those that do not support threads.

The type table implements associative arrays, that is, arrays that can be indexed not only with numbers, but with any value (except nil). Tables can be heterogeneous; that is, they can contain values of all types (except nil). Tables are the sole data structuring mechanism in Lua; they can be used to represent ordinary arrays, symbol tables, sets, records, graphs, trees, etc. To represent records, Lua uses the field name as an index. The language supports this representation by providing a.name as syntactic sugar for a["name"]. There are several convenient ways to create tables in Lua (see §2.5.7).

Like indices, the value of a table field can be of any type (except nil). In particular, because functions are first-class values, table fields can contain functions. Thus tables can also carry methods (see §2.5.9).

Tables, functions, threads, and (full) userdata values are objects: variables do not actually contain these values, only references to them. Assignment, parameter passing, and function returns always manipulate references to such values; these operations do not imply any kind of copy.

The library function type returns a string describing the type of a given value.

2.2.1 - Coercion

Lua provides automatic conversion between string and number values at run time. Any arithmetic operation applied to a string tries to convert this string to a number, following the usual conversion rules. Conversely, whenever a number is used where a string is expected, the number is converted to a string, in a reasonable format. For complete control over how numbers are converted to strings, use the format function from the string library (see string.format).

2.3 - Variables

Variables are places that store values. There are three kinds of variables in Lua: global variables, local variables, and table fields.

A single name can denote a global variable or a local variable (or a function's formal parameter, which is a particular kind of local variable): 

	var ::= Name

Name denotes identifiers, as defined in §2.1.

Any variable is assumed to be global unless explicitly declared as a local (see §2.4.7). Local variables are lexically scoped: local variables can be freely accessed by functions defined inside their scope (see §2.6).

Before the first assignment to a variable, its value is nil.

Square brackets are used to index a table: 

	var ::= prefixexp `[´ exp `]´

The meaning of accesses to global variables and table fields can be changed via metatables. An access to an indexed variable t[i] is equivalent to a call gettable_event(t,i). (See §2.8 for a complete description of the gettable_event function. This function is not defined or callable in Lua. We use it here only for explanatory purposes.)

The syntax var.Name is just syntactic sugar for var["Name"]: 

	var ::= prefixexp `.´ Name

All global variables live as fields in ordinary Lua tables, called environment tables or simply environments (see §2.9). Each function has its own reference to an environment, so that all global variables in this function will refer to this environment table. When a function is created, it inherits the environment from the function that created it. To get the environment table of a Lua function, you call getfenv. To replace it, you call setfenv. (You can only manipulate the environment of C functions through the debug library; (see §5.9).)

An access to a global variable x is equivalent to _env.x, which in turn is equivalent to 

     gettable_event(_env, "x")

where _env is the environment of the running function. (See §2.8 for a complete description of the gettable_event function. This function is not defined or callable in Lua. Similarly, the _env variable is not defined in Lua. We use them here only for explanatory purposes.)

2.4 - Statements

Lua supports an almost conventional set of statements, similar to those in Pascal or C. This set includes assignments, control structures, function calls, and variable declarations.

2.4.1 - Chunks

The unit of execution of Lua is called a chunk. A chunk is simply a sequence of statements, which are executed sequentially. Each statement can be optionally followed by a semicolon: 

	chunk ::= {stat [`;´]}

There are no empty statements and thus ';;' is not legal.

Lua handles a chunk as the body of an anonymous function with a variable number of arguments (see §2.5.9). As such, chunks can define local variables, receive arguments, and return values.

A chunk can be stored in a file or in a string inside the host program. To execute a chunk, Lua first pre-compiles the chunk into instructions for a virtual machine, and then it executes the compiled code with an interpreter for the virtual machine.

Chunks can also be pre-compiled into binary form; see program luac for details. Programs in source and compiled forms are interchangeable; Lua automatically detects the file type and acts accordingly.

2.4.2 - Blocks

A block is a list of statements; syntactically, a block is the same as a chunk: 

	block ::= chunk

A block can be explicitly delimited to produce a single statement: 

	stat ::= do block end

Explicit blocks are useful to control the scope of variable declarations. Explicit blocks are also sometimes used to add a return or break statement in the middle of another block (see §2.4.4).

2.4.3 - Assignment

Lua allows multiple assignments. Therefore, the syntax for assignment defines a list of variables on the left side and a list of expressions on the right side. The elements in both lists are separated by commas: 

	stat ::= varlist `=´ explist
	varlist ::= var {`,´ var}
	explist ::= exp {`,´ exp}

Expressions are discussed in §2.5.

Before the assignment, the list of values is adjusted to the length of the list of variables. If there are more values than needed, the excess values are thrown away. If there are fewer values than needed, the list is extended with as many nil's as needed. If the list of expressions ends with a function call, then all values returned by that call enter the list of values, before the adjustment (except when the call is enclosed in parentheses; see §2.5).

The assignment statement first evaluates all its expressions and only then are the assignments performed. Thus the code 

     i = 3
     i, a[i] = i+1, 20

sets a[3] to 20, without affecting a[4] because the i in a[i] is evaluated (to 3) before it is assigned 4. Similarly, the line 

     x, y = y, x

exchanges the values of x and y, and 

     x, y, z = y, z, x

cyclically permutes the values of x, y, and z.

The meaning of assignments to global variables and table fields can be changed via metatables. An assignment to an indexed variable t[i] = val is equivalent to settable_event(t,i,val). (See §2.8 for a complete description of the settable_event function. This function is not defined or callable in Lua. We use it here only for explanatory purposes.)

An assignment to a global variable x = val is equivalent to the assignment _env.x = val, which in turn is equivalent to 

     settable_event(_env, "x", val)

where _env is the environment of the running function. (The _env variable is not defined in Lua. We use it here only for explanatory purposes.)

2.4.4 - Control Structures

The control structures if, while, and repeat have the usual meaning and familiar syntax: 

	stat ::= while exp do block end
	stat ::= repeat block until exp
	stat ::= if exp then block {elseif exp then block} [else block] end

Lua also has a for statement, in two flavors (see §2.4.5).

The condition expression of a control structure can return any value. Both false and nil are considered false. All values different from nil and false are considered true (in particular, the number 0 and the empty string are also true).

In the repeat–until loop, the inner block does not end at the until keyword, but only after the condition. So, the condition can refer to local variables declared inside the loop block.

The return statement is used to return values from a function or a chunk (which is just a function). Functions and chunks can return more than one value, and so the syntax for the return statement is 

	stat ::= return [explist]

The break statement is used to terminate the execution of a while, repeat, or for loop, skipping to the next statement after the loop: 

	stat ::= break

A break ends the innermost enclosing loop.

The return and break statements can only be written as the last statement of a block. If it is really necessary to return or break in the middle of a block, then an explicit inner block can be used, as in the idioms do return end and do break end, because now return and break are the last statements in their (inner) blocks.

2.4.5 - For Statement

The for statement has two forms: one numeric and one generic.

The numeric for loop repeats a block of code while a control variable runs through an arithmetic progression. It has the following syntax: 

	stat ::= for Name `=´ exp `,´ exp [`,´ exp] do block end

The block is repeated for name starting at the value of the first exp, until it passes the second exp by steps of the third exp. More precisely, a for statement like 

     for v = e1, e2, e3 do block end

is equivalent to the code: 

     do
       local var, limit, step = tonumber(e1), tonumber(e2), tonumber(e3)
       if not (var and limit and step) then error() end
       while (step > 0 and var <= limit) or (step <= 0 and var >= limit) do
         local v = var
         block
         var = var + step
       end
     end

Note the following:

  • All three control expressions are evaluated only once, before the loop starts. They must all result in numbers.
  • var, limit, and step are invisible variables. The names shown here are for explanatory purposes only.
  • If the third expression (the step) is absent, then a step of 1 is used.
  • You can use break to exit a for loop.
  • The loop variable v is local to the loop; you cannot use its value after the for ends or is broken. If you need this value, assign it to another variable before breaking or exiting the loop.

The generic for statement works over functions, called iterators. On each iteration, the iterator function is called to produce a new value, stopping when this new value is nil. The generic for loop has the following syntax: 

	stat ::= for namelist in explist do block end
	namelist ::= Name {`,´ Name}

A for statement like 

     for var_1, ···, var_n in explist do block end

is equivalent to the code: 

     do
       local f, s, var = explist
       while true do
         local var_1, ···, var_n = f(s, var)
         var = var_1
         if var == nil then break end
         block
       end
     end

Note the following:

  • explist is evaluated only once. Its results are an iterator function, a state, and an initial value for the first iterator variable.
  • f, s, and var are invisible variables. The names are here for explanatory purposes only.
  • You can use break to exit a for loop.
  • The loop variables var_i are local to the loop; you cannot use their values after the for ends. If you need these values, then assign them to other variables before breaking or exiting the loop.

2.4.6 - Function Calls as Statements

To allow possible side-effects, function calls can be executed as statements: 

	stat ::= functioncall

In this case, all returned values are thrown away. Function calls are explained in §2.5.8.

2.4.7 - Local Declarations

Local variables can be declared anywhere inside a block. The declaration can include an initial assignment: 

	stat ::= local namelist [`=´ explist]

If present, an initial assignment has the same semantics of a multiple assignment (see §2.4.3). Otherwise, all variables are initialized with nil.

A chunk is also a block (see §2.4.1), and so local variables can be declared in a chunk outside any explicit block. The scope of such local variables extends until the end of the chunk.

The visibility rules for local variables are explained in §2.6.

2.5 - Expressions

The basic expressions in Lua are the following: 

	exp ::= prefixexp
	exp ::= nil | false | true
	exp ::= Number
	exp ::= String
	exp ::= function
	exp ::= tableconstructor
	exp ::= `...´
	exp ::= exp binop exp
	exp ::= unop exp
	prefixexp ::= var | functioncall | `(´ exp `)´

Numbers and literal strings are explained in §2.1; variables are explained in §2.3; function definitions are explained in §2.5.9; function calls are explained in §2.5.8; table constructors are explained in §2.5.7. Vararg expressions, denoted by three dots ('...'), can only be used when directly inside a vararg function; they are explained in §2.5.9.

Binary operators comprise arithmetic operators (see §2.5.1), relational operators (see §2.5.2), logical operators (see §2.5.3), and the concatenation operator (see §2.5.4). Unary operators comprise the unary minus (see §2.5.1), the unary not (see §2.5.3), and the unary length operator (see §2.5.5).

Both function calls and vararg expressions can result in multiple values. If an expression is used as a statement (only possible for function calls (see §2.4.6)), then its return list is adjusted to zero elements, thus discarding all returned values. If an expression is used as the last (or the only) element of a list of expressions, then no adjustment is made (unless the call is enclosed in parentheses). In all other contexts, Lua adjusts the result list to one element, discarding all values except the first one.

Here are some examples: 

     f()                -- adjusted to 0 results
     g(f(), x)          -- f() is adjusted to 1 result
     g(x, f())          -- g gets x plus all results from f()
     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
     a,b = ...          -- a gets the first vararg parameter, b gets
                        -- the second (both a and b can get nil if there
                        -- is no corresponding vararg parameter)
     
     a,b,c = x, f()     -- f() is adjusted to 2 results
     a,b,c = f()        -- f() is adjusted to 3 results
     return f()         -- returns all results from f()
     return ...         -- returns all received vararg parameters
     return x,y,f()     -- returns x, y, and all results from f()
     {f()}              -- creates a list with all results from f()
     {...}              -- creates a list with all vararg parameters
     {f(), nil}         -- f() is adjusted to 1 result

Any expression enclosed in parentheses always results in only one value. Thus, (f(x,y,z)) is always a single value, even if f returns several values. (The value of (f(x,y,z)) is the first value returned by f or nil if f does not return any values.)

2.5.1 - Arithmetic Operators

Lua supports the usual arithmetic operators: the binary + (addition), - (subtraction), * (multiplication), / (division), % (modulo), and ^ (exponentiation); and unary - (negation). If the operands are numbers, or strings that can be converted to numbers (see §2.2.1), then all operations have the usual meaning. Exponentiation works for any exponent. For instance, x^(-0.5) computes the inverse of the square root of x. Modulo is defined as 

     a % b == a - math.floor(a/b)*b

That is, it is the remainder of a division that rounds the quotient towards minus infinity.

2.5.2 - Relational Operators

The relational operators in Lua are 

     ==    ~=    <     >     <=    >=

These operators always result in false or true.

Equality (==) first compares the type of its operands. If the types are different, then the result is false. Otherwise, the values of the operands are compared. Numbers and strings are compared in the usual way. Objects (tables, userdata, threads, and functions) are compared by reference: two objects are considered equal only if they are the same object. Every time you create a new object (a table, userdata, thread, or function), this new object is different from any previously existing object.

You can change the way that Lua compares tables and userdata by using the "eq" metamethod (see §2.8).

The conversion rules of §2.2.1 do not apply to equality comparisons. Thus, "0"==0 evaluates to false, and t[0] and t["0"] denote different entries in a table.

The operator ~= is exactly the negation of equality (==).

The order operators work as follows. If both arguments are numbers, then they are compared as such. Otherwise, if both arguments are strings, then their values are compared according to the current locale. Otherwise, Lua tries to call the "lt" or the "le" metamethod (see §2.8). A comparison a > b is translated to b < a and a >= b is translated to b <= a.

2.5.3 - Logical Operators

The logical operators in Lua are and, or, and not. Like the control structures (see §2.4.4), all logical operators consider both false and nil as false and anything else as true.

The negation operator not always returns false or true. The conjunction operator and returns its first argument if this value is false or nil; otherwise, and returns its second argument. The disjunction operator or returns its first argument if this value is different from nil and false; otherwise, or returns its second argument. Both and and or use short-cut evaluation; that is, the second operand is evaluated only if necessary. Here are some examples: 

     10 or 20            --> 10
     10 or error()       --> 10
     nil or "a"          --> "a"
     nil and 10          --> nil
     false and error()   --> false
     false and nil       --> false
     false or nil        --> nil
     10 and 20           --> 20

(In this manual, --> indicates the result of the preceding expression.)

2.5.4 - Concatenation

The string concatenation operator in Lua is denoted by two dots ('..'). If both operands are strings or numbers, then they are converted to strings according to the rules mentioned in §2.2.1. Otherwise, the "concat" metamethod is called (see §2.8).

2.5.5 - The Length Operator

The length operator is denoted by the unary operator #. The length of a string is its number of bytes (that is, the usual meaning of string length when each character is one byte).

The length of a table t is defined to be any integer index n such that t[n] is not nil and t[n+1] is nil; moreover, if t[1] is nil, n can be zero. For a regular array, with non-nil values from 1 to a given n, its length is exactly that n, the index of its last value. If the array has "holes" (that is, nil values between other non-nil values), then #t can be any of the indices that directly precedes a nil value (that is, it may consider any such nil value as the end of the array).

2.5.6 - Precedence

Operator precedence in Lua follows the table below, from lower to higher priority: 

     or
     and
     <     >     <=    >=    ~=    ==
     ..
     +     -
     *     /     %
     not   #     - (unary)
     ^

As usual, you can use parentheses to change the precedences of an expression. The concatenation ('..') and exponentiation ('^') operators are right associative. All other binary operators are left associative.

2.5.7 - Table Constructors

Table constructors are expressions that create tables. Every time a constructor is evaluated, a new table is created. A constructor can be used to create an empty table or to create a table and initialize some of its fields. The general syntax for constructors is 

	tableconstructor ::= `{´ [fieldlist] `}´
	fieldlist ::= field {fieldsep field} [fieldsep]
	field ::= `[´ exp `]´ `=´ exp | Name `=´ exp | exp
	fieldsep ::= `,´ | `;´

Each field of the form [exp1] = exp2 adds to the new table an entry with key exp1 and value exp2. A field of the form name = exp is equivalent to ["name"] = exp. Finally, fields of the form exp are equivalent to [i] = exp, where i are consecutive numerical integers, starting with 1. Fields in the other formats do not affect this counting. For example, 

     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }

is equivalent to 

     do
       local t = {}
       t[f(1)] = g
       t[1] = "x"         -- 1st exp
       t[2] = "y"         -- 2nd exp
       t.x = 1            -- t["x"] = 1
       t[3] = f(x)        -- 3rd exp
       t[30] = 23
       t[4] = 45          -- 4th exp
       a = t
     end

If the last field in the list has the form exp and the expression is a function call or a vararg expression, then all values returned by this expression enter the list consecutively (see §2.5.8). To avoid this, enclose the function call or the vararg expression in parentheses (see §2.5).

The field list can have an optional trailing separator, as a convenience for machine-generated code.

2.5.8 - Function Calls

A function call in Lua has the following syntax: 

	functioncall ::= prefixexp args

In a function call, first prefixexp and args are evaluated. If the value of prefixexp has type function, then this function is called with the given arguments. Otherwise, the prefixexp "call" metamethod is called, having as first parameter the value of prefixexp, followed by the original call arguments (see §2.8).

The form 

	functioncall ::= prefixexp `:´ Name args

can be used to call "methods". A call v:name(args) is syntactic sugar for v.name(v,args), except that v is evaluated only once.

Arguments have the following syntax: 

	args ::= `(´ [explist] `)´
	args ::= tableconstructor
	args ::= String

All argument expressions are evaluated before the call. A call of the form f{fields} is syntactic sugar for f({fields}); that is, the argument list is a single new table. A call of the form f'string' (or f"string" or f[[string]]) is syntactic sugar for f('string'); that is, the argument list is a single literal string.

As an exception to the free-format syntax of Lua, you cannot put a line break before the '(' in a function call. This restriction avoids some ambiguities in the language. If you write 

     a = f
     (g).x(a)

Lua would see that as a single statement, a = f(g).x(a). So, if you want two statements, you must add a semi-colon between them. If you actually want to call f, you must remove the line break before (g).

A call of the form return functioncall is called a tail call. Lua implements proper tail calls (or proper tail recursion): in a tail call, the called function reuses the stack entry of the calling function. Therefore, there is no limit on the number of nested tail calls that a program can execute. However, a tail call erases any debug information about the calling function. Note that a tail call only happens with a particular syntax, where the return has one single function call as argument; this syntax makes the calling function return exactly the returns of the called function. So, none of the following examples are tail calls: 

     return (f(x))        -- results adjusted to 1
     return 2 * f(x)
     return x, f(x)       -- additional results
     f(x); return         -- results discarded
     return x or f(x)     -- results adjusted to 1

2.5.9 - Function Definitions

The syntax for function definition is 

	function ::= function funcbody
	funcbody ::= `(´ [parlist] `)´ block end

The following syntactic sugar simplifies function definitions: 

	stat ::= function funcname funcbody
	stat ::= local function Name funcbody
	funcname ::= Name {`.´ Name} [`:´ Name]

The statement 

     function f () body end

translates to 

     f = function () body end

The statement 

     function t.a.b.c.f () body end

translates to 

     t.a.b.c.f = function () body end

The statement 

     local function f () body end

translates to 

     local f; f = function () body end

not to 

     local f = function () body end

(This only makes a difference when the body of the function contains references to f.)

A function definition is an executable expression, whose value has type function. When Lua pre-compiles a chunk, all its function bodies are pre-compiled too. Then, whenever Lua executes the function definition, the function is instantiated (or closed). This function instance (or closure) is the final value of the expression. Different instances of the same function can refer to different external local variables and can have different environment tables.

Parameters act as local variables that are initialized with the argument values: 

	parlist ::= namelist [`,´ `...´] | `...´

When a function is called, the list of arguments is adjusted to the length of the list of parameters, unless the function is a variadic or vararg function, which is indicated by three dots ('...') at the end of its parameter list. A vararg function does not adjust its argument list; instead, it collects all extra arguments and supplies them to the function through a vararg expression, which is also written as three dots. The value of this expression is a list of all actual extra arguments, similar to a function with multiple results. If a vararg expression is used inside another expression or in the middle of a list of expressions, then its return list is adjusted to one element. If the expression is used as the last element of a list of expressions, then no adjustment is made (unless that last expression is enclosed in parentheses).

As an example, consider the following definitions: 

     function f(a, b) end
     function g(a, b, ...) end
     function r() return 1,2,3 end

Then, we have the following mapping from arguments to parameters and to the vararg expression: 

     CALL            PARAMETERS
     
     f(3)             a=3, b=nil
     f(3, 4)          a=3, b=4
     f(3, 4, 5)       a=3, b=4
     f(r(), 10)       a=1, b=10
     f(r())           a=1, b=2
     
     g(3)             a=3, b=nil, ... -->  (nothing)
     g(3, 4)          a=3, b=4,   ... -->  (nothing)
     g(3, 4, 5, 8)    a=3, b=4,   ... -->  5  8
     g(5, r())        a=5, b=1,   ... -->  2  3

Results are returned using the return statement (see §2.4.4). If control reaches the end of a function without encountering a return statement, then the function returns with no results.

The colon syntax is used for defining methods, that is, functions that have an implicit extra parameter self. Thus, the statement 

     function t.a.b.c:f (params) body end

is syntactic sugar for 

     t.a.b.c.f = function (self, params) body end

2.6 - Visibility Rules

Lua is a lexically scoped language. The scope of variables begins at the first statement after their declaration and lasts until the end of the innermost block that includes the declaration. Consider the following example: 

     x = 10                -- global variable
     do                    -- new block
       local x = x         -- new 'x', with value 10
       print(x)            --> 10
       x = x+1
       do                  -- another block
         local x = x+1     -- another 'x'
         print(x)          --> 12
       end
       print(x)            --> 11
     end
     print(x)              --> 10  (the global one)

Notice that, in a declaration like local x = x, the new x being declared is not in scope yet, and so the second x refers to the outside variable.

Because of the lexical scoping rules, local variables can be freely accessed by functions defined inside their scope. A local variable used by an inner function is called an upvalue, or external local variable, inside the inner function.

Notice that each execution of a local statement defines new local variables. Consider the following example: 

     a = {}
     local x = 20
     for i=1,10 do
       local y = 0
       a[i] = function () y=y+1; return x+y end
     end

The loop creates ten closures (that is, ten instances of the anonymous function). Each of these closures uses a different y variable, while all of them share the same x.

2.7 - Error Handling

Because Lua is an embedded extension language, all Lua actions start from C code in the host program calling a function from the Lua library (see lua_pcall). Whenever an error occurs during Lua compilation or execution, control returns to C, which can take appropriate measures (such as printing an error message).

Lua code can explicitly generate an error by calling the error function. If you need to catch errors in Lua, you can use the pcall function.

2.8 - Metatables

Every value in Lua can have a metatable. This metatable is an ordinary Lua table that defines the behavior of the original value under certain special operations. You can change several aspects of the behavior of operations over a value by setting specific fields in its metatable. For instance, when a non-numeric value is the operand of an addition, Lua checks for a function in the field "__add" in its metatable. If it finds one, Lua calls this function to perform the addition.

We call the keys in a metatable events and the values metamethods. In the previous example, the event is "add" and the metamethod is the function that performs the addition.

You can query the metatable of any value through the getmetatable function.

You can replace the metatable of tables through the setmetatable function. You cannot change the metatable of other types from Lua (except by using the debug library); you must use the C API for that.

Tables and full userdata have individual metatables (although multiple tables and userdata can share their metatables). Values of all other types share one single metatable per type; that is, there is one single metatable for all numbers, one for all strings, etc.

A metatable controls how an object behaves in arithmetic operations, order comparisons, concatenation, length operation, and indexing. A metatable also can define a function to be called when a userdata is garbage collected. For each of these operations Lua associates a specific key called an event. When Lua performs one of these operations over a value, it checks whether this value has a metatable with the corresponding event. If so, the value associated with that key (the metamethod) controls how Lua will perform the operation.

Metatables control the operations listed next. Each operation is identified by its corresponding name. The key for each operation is a string with its name prefixed by two underscores, '__'; for instance, the key for operation "add" is the string "__add". The semantics of these operations is better explained by a Lua function describing how the interpreter executes the operation.

The code shown here in Lua is only illustrative; the real behavior is hard coded in the interpreter and it is much more efficient than this simulation. All functions used in these descriptions (rawget, tonumber, etc.) are described in §5.1. In particular, to retrieve the metamethod of a given object, we use the expression 

     metatable(obj)[event]

This should be read as 

     rawget(getmetatable(obj) or {}, event)

That is, the access to a metamethod does not invoke other metamethods, and the access to objects with no metatables does not fail (it simply results in nil).

  • "add": the + operation.

    The function getbinhandler below defines how Lua chooses a handler for a binary operation. First, Lua tries the first operand. If its type does not define a handler for the operation, then Lua tries the second operand. 

         function getbinhandler (op1, op2, event)
       return metatable(op1)[event] or metatable(op2)[event]
     end

    By using this function, the behavior of the op1 + op2 is 

         function add_event (op1, op2)
       local o1, o2 = tonumber(op1), tonumber(op2)
       if o1 and o2 then  -- both operands are numeric?
         return o1 + o2   -- '+' here is the primitive 'add'
       else  -- at least one of the operands is not numeric
         local h = getbinhandler(op1, op2, "__add")
         if h then
           -- call the handler with both operands
           return (h(op1, op2))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

  • "sub": the - operation. Behavior similar to the "add" operation.
  • "mul": the * operation. Behavior similar to the "add" operation.
  • "div": the / operation. Behavior similar to the "add" operation.
  • "mod": the % operation. Behavior similar to the "add" operation, with the operation o1 - floor(o1/o2)*o2 as the primitive operation.
  • "pow": the ^ (exponentiation) operation. Behavior similar to the "add" operation, with the function pow (from the C math library) as the primitive operation.
  • "unm": the unary - operation. 
         function unm_event (op)
       local o = tonumber(op)
       if o then  -- operand is numeric?
         return -o  -- '-' here is the primitive 'unm'
       else  -- the operand is not numeric.
         -- Try to get a handler from the operand
         local h = metatable(op).__unm
         if h then
           -- call the handler with the operand
           return (h(op))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

  • "concat": the .. (concatenation) operation. 
         function concat_event (op1, op2)
       if (type(op1) == "string" or type(op1) == "number") and
          (type(op2) == "string" or type(op2) == "number") then
         return op1 .. op2  -- primitive string concatenation
       else
         local h = getbinhandler(op1, op2, "__concat")
         if h then
           return (h(op1, op2))
         else
           error(···)
         end
       end
     end

  • "len": the # operation. 
         function len_event (op)
       if type(op) == "string" then
         return strlen(op)         -- primitive string length
       elseif type(op) == "table" then
         return #op                -- primitive table length
       else
         local h = metatable(op).__len
         if h then
           -- call the handler with the operand
           return (h(op))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

    See §2.5.5 for a description of the length of a table.

  • "eq": the == operation. The function getcomphandler defines how Lua chooses a metamethod for comparison operators. A metamethod only is selected when both objects being compared have the same type and the same metamethod for the selected operation. 
         function getcomphandler (op1, op2, event)
       if type(op1) ~= type(op2) then return nil end
       local mm1 = metatable(op1)[event]
       local mm2 = metatable(op2)[event]
       if mm1 == mm2 then return mm1 else return nil end
     end

    The "eq" event is defined as follows: 

         function eq_event (op1, op2)
       if type(op1) ~= type(op2) then  -- different types?
         return false   -- different objects
       end
       if op1 == op2 then   -- primitive equal?
         return true   -- objects are equal
       end
       -- try metamethod
       local h = getcomphandler(op1, op2, "__eq")
       if h then
         return (h(op1, op2))
       else
         return false
       end
     end

    a ~= b is equivalent to not (a == b).

  • "lt": the < operation. 
         function lt_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 < op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 < op2   -- lexicographic comparison
       else
         local h = getcomphandler(op1, op2, "__lt")
         if h then
           return (h(op1, op2))
         else
           error(···)
         end
       end
     end

    a > b is equivalent to b < a.

  • "le": the <= operation. 
         function le_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 <= op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 <= op2   -- lexicographic comparison
       else
         local h = getcomphandler(op1, op2, "__le")
         if h then
           return (h(op1, op2))
         else
           h = getcomphandler(op1, op2, "__lt")
           if h then
             return not h(op2, op1)
           else
             error(···)
           end
         end
       end
     end

    a >= b is equivalent to b <= a. Note that, in the absence of a "le" metamethod, Lua tries the "lt", assuming that a <= b is equivalent to not (b < a).

  • "index": The indexing access table[key]. 
         function gettable_event (table, key)
       local h
       if type(table) == "table" then
         local v = rawget(table, key)
         if v ~= nil then return v end
         h = metatable(table).__index
         if h == nil then return nil end
       else
         h = metatable(table).__index
         if h == nil then
           error(···)
         end
       end
       if type(h) == "function" then
         return (h(table, key))     -- call the handler
       else return h[key]           -- or repeat operation on it
       end
     end

  • "newindex": The indexing assignment table[key] = value. 
         function settable_event (table, key, value)
       local h
       if type(table) == "table" then
         local v = rawget(table, key)
         if v ~= nil then rawset(table, key, value); return end
         h = metatable(table).__newindex
         if h == nil then rawset(table, key, value); return end
       else
         h = metatable(table).__newindex
         if h == nil then
           error(···)
         end
       end
       if type(h) == "function" then
         h(table, key,value)           -- call the handler
       else h[key] = value             -- or repeat operation on it
       end
     end

  • "call": called when Lua calls a value. 
         function function_event (func, ...)
       if type(func) == "function" then
         return func(...)   -- primitive call
       else
         local h = metatable(func).__call
         if h then
           return h(func, ...)
         else
           error(···)
         end
       end
     end

2.9 - Environments

Besides metatables, objects of types thread, function, and userdata have another table associated with them, called their environment. Like metatables, environments are regular tables and multiple objects can share the same environment.

Threads are created sharing the environment of the creating thread. Userdata and C functions are created sharing the environment of the creating C function. Non-nested Lua functions (created by loadfile, loadstring or load) are created sharing the environment of the creating thread. Nested Lua functions are created sharing the environment of the creating Lua function.

Environments associated with userdata have no meaning for Lua. It is only a convenience feature for programmers to associate a table to a userdata.

Environments associated with threads are called global environments. They are used as the default environment for threads and non-nested Lua functions created by the thread and can be directly accessed by C code (see §3.3).

The environment associated with a C function can be directly accessed by C code (see §3.3). It is used as the default environment for other C functions and userdata created by the function.

Environments associated with Lua functions are used to resolve all accesses to global variables within the function (see §2.3). They are used as the default environment for nested Lua functions created by the function.

You can change the environment of a Lua function or the running thread by calling setfenv. You can get the environment of a Lua function or the running thread by calling getfenv. To manipulate the environment of other objects (userdata, C functions, other threads) you must use the C API.

2.10 - Garbage Collection

Lua performs automatic memory management. This means that you have to worry neither about allocating memory for new objects nor about freeing it when the objects are no longer needed. Lua manages memory automatically by running a garbage collector from time to time to collect all dead objects (that is, objects that are no longer accessible from Lua). All memory used by Lua is subject to automatic management: tables, userdata, functions, threads, strings, etc.

Lua implements an incremental mark-and-sweep collector. It uses two numbers to control its garbage-collection cycles: the garbage-collector pause and the garbage-collector step multiplier. Both use percentage points as units (so that a value of 100 means an internal value of 1).

The garbage-collector pause controls how long the collector waits before starting a new cycle. Larger values make the collector less aggressive. Values smaller than 100 mean the collector will not wait to start a new cycle. A value of 200 means that the collector waits for the total memory in use to double before starting a new cycle.

The step multiplier controls the relative speed of the collector relative to memory allocation. Larger values make the collector more aggressive but also increase the size of each incremental step. Values smaller than 100 make the collector too slow and can result in the collector never finishing a cycle. The default, 200, means that the collector runs at "twice" the speed of memory allocation.

You can change these numbers by calling lua_gc in C or collectgarbage in Lua. With these functions you can also control the collector directly (e.g., stop and restart it).

2.10.1 - Garbage-Collection Metamethods

Using the C API, you can set garbage-collector metamethods for userdata (see §2.8). These metamethods are also called finalizers. Finalizers allow you to coordinate Lua's garbage collection with external resource management (such as closing files, network or database connections, or freeing your own memory).

Garbage userdata with a field __gc in their metatables are not collected immediately by the garbage collector. Instead, Lua puts them in a list. After the collection, Lua does the equivalent of the following function for each userdata in that list: 

     function gc_event (udata)
       local h = metatable(udata).__gc
       if h then
         h(udata)
       end
     end

At the end of each garbage-collection cycle, the finalizers for userdata are called in reverse order of their creation, among those collected in that cycle. That is, the first finalizer to be called is the one associated with the userdata created last in the program. The userdata itself is freed only in the next garbage-collection cycle.

2.10.2 - Weak Tables

A weak table is a table whose elements are weak references. A weak reference is ignored by the garbage collector. In other words, if the only references to an object are weak references, then the garbage collector will collect this object.

A weak table can have weak keys, weak values, or both. A table with weak keys allows the collection of its keys, but prevents the collection of its values. A table with both weak keys and weak values allows the collection of both keys and values. In any case, if either the key or the value is collected, the whole pair is removed from the table. The weakness of a table is controlled by the __mode field of its metatable. If the __mode field is a string containing the character 'k', the keys in the table are weak. If __mode contains 'v', the values in the table are weak.

After you use a table as a metatable, you should not change the value of its __mode field. Otherwise, the weak behavior of the tables controlled by this metatable is undefined.

2.11 - Coroutines

Lua supports coroutines, also called collaborative multithreading. A coroutine in Lua represents an independent thread of execution. Unlike threads in multithread systems, however, a coroutine only suspends its execution by explicitly calling a yield function.

You create a coroutine with a call to coroutine.create. Its sole argument is a function that is the main function of the coroutine. The create function only creates a new coroutine and returns a handle to it (an object of type thread); it does not start the coroutine execution.

When you first call coroutine.resume, passing as its first argument a thread returned by coroutine.create, the coroutine starts its execution, at the first line of its main function. Extra arguments passed to coroutine.resume are passed on to the coroutine main function. After the coroutine starts running, it runs until it terminates or yields.

A coroutine can terminate its execution in two ways: normally, when its main function returns (explicitly or implicitly, after the last instruction); and abnormally, if there is an unprotected error. In the first case, coroutine.resume returns true, plus any values returned by the coroutine main function. In case of errors, coroutine.resume returns false plus an error message.

A coroutine yields by calling coroutine.yield. When a coroutine yields, the corresponding coroutine.resume returns immediately, even if the yield happens inside nested function calls (that is, not in the main function, but in a function directly or indirectly called by the main function). In the case of a yield, coroutine.resume also returns true, plus any values passed to coroutine.yield. The next time you resume the same coroutine, it continues its execution from the point where it yielded, with the call to coroutine.yield returning any extra arguments passed to coroutine.resume.

Like coroutine.create, the coroutine.wrap function also creates a coroutine, but instead of returning the coroutine itself, it returns a function that, when called, resumes the coroutine. Any arguments passed to this function go as extra arguments to coroutine.resume. coroutine.wrap returns all the values returned by coroutine.resume, except the first one (the boolean error code). Unlike coroutine.resume, coroutine.wrap does not catch errors; any error is propagated to the caller.

As an example, consider the following code: 

     function foo (a)
       print("foo", a)
       return coroutine.yield(2*a)
     end
     
     co = coroutine.create(function (a,b)
           print("co-body", a, b)
           local r = foo(a+1)
           print("co-body", r)
           local r, s = coroutine.yield(a+b, a-b)
           print("co-body", r, s)
           return b, "end"
     end)
            
     print("main", coroutine.resume(co, 1, 10))
     print("main", coroutine.resume(co, "r"))
     print("main", coroutine.resume(co, "x", "y"))
     print("main", coroutine.resume(co, "x", "y"))

When you run it, it produces the following output: 

     co-body 1       10
     foo     2
     
     main    true    4
     co-body r
     main    true    11      -9
     co-body x       y
     main    true    10      end
     main    false   cannot resume dead coroutine

3 - The Application Program Interface

This section describes the C API for Lua, that is, the set of C functions available to the host program to communicate with Lua. All API functions and related types and constants are declared in the header file lua.h.

Even when we use the term "function", any facility in the API may be provided as a macro instead. All such macros use each of their arguments exactly once (except for the first argument, which is always a Lua state), and so do not generate any hidden side-effects.

As in most C libraries, the Lua API functions do not check their arguments for validity or consistency. However, you can change this behavior by compiling Lua with a proper definition for the macro luai_apicheck, in file luaconf.h.

3.1 - The Stack

Lua uses a virtual stack to pass values to and from C. Each element in this stack represents a Lua value (nil, number, string, etc.).

Whenever Lua calls C, the called function gets a new stack, which is independent of previous stacks and of stacks of C functions that are still active. This stack initially contains any arguments to the C function and it is where the C function pushes its results to be returned to the caller (see lua_CFunction).

For convenience, most query operations in the API do not follow a strict stack discipline. Instead, they can refer to any element in the stack by using an index: A positive index represents an absolute stack position (starting at 1); a negative index represents an offset relative to the top of the stack. More specifically, if the stack has n elements, then index 1 represents the first element (that is, the element that was pushed onto the stack first) and index n represents the last element; index -1 also represents the last element (that is, the element at the top) and index -n represents the first element. We say that an index is valid if it lies between 1 and the stack top (that is, if 1 ≤ abs(index) ≤ top).

3.2 - Stack Size

When you interact with Lua API, you are responsible for ensuring consistency. In particular, you are responsible for controlling stack overflow. You can use the function lua_checkstack to grow the stack size.

Whenever Lua calls C, it ensures that at least LUA_MINSTACK stack positions are available. LUA_MINSTACK is defined as 20, so that usually you do not have to worry about stack space unless your code has loops pushing elements onto the stack.

Most query functions accept as indices any value inside the available stack space, that is, indices up to the maximum stack size you have set through lua_checkstack. Such indices are called acceptable indices. More formally, we define an acceptable index as follows: 

     (index < 0 && abs(index) <= top) ||
     (index > 0 && index <= stackspace)

Note that 0 is never an acceptable index.

3.3 - Pseudo-Indices

Unless otherwise noted, any function that accepts valid indices can also be called with pseudo-indices, which represent some Lua values that are accessible to C code but which are not in the stack. Pseudo-indices are used to access the thread environment, the function environment, the registry, and the upvalues of a C function (see §3.4).

The thread environment (where global variables live) is always at pseudo-index LUA_GLOBALSINDEX. The environment of the running C function is always at pseudo-index LUA_ENVIRONINDEX.

To access and change the value of global variables, you can use regular table operations over an environment table. For instance, to access the value of a global variable, do 

     lua_getfield(L, LUA_GLOBALSINDEX, varname);

3.4 - C Closures

When a C function is created, it is possible to associate some values with it, thus creating a C closure; these values are called upvalues and are accessible to the function whenever it is called (see lua_pushcclosure).

Whenever a C function is called, its upvalues are located at specific pseudo-indices. These pseudo-indices are produced by the macro lua_upvalueindex. The first value associated with a function is at position lua_upvalueindex(1), and so on. Any access to lua_upvalueindex(n), where n is greater than the number of upvalues of the current function (but not greater than 256), produces an acceptable (but invalid) index.

3.5 - Registry

Lua provides a registry, a pre-defined table that can be used by any C code to store whatever Lua value it needs to store. This table is always located at pseudo-index LUA_REGISTRYINDEX. Any C library can store data into this table, but it should take care to choose keys different from those used by other libraries, to avoid collisions. Typically, you should use as key a string containing your library name or a light userdata with the address of a C object in your code.

The integer keys in the registry are used by the reference mechanism, implemented by the auxiliary library, and therefore should not be used for other purposes.

3.6 - Error Handling in C

Internally, Lua uses the C longjmp facility to handle errors. (You can also choose to use exceptions if you use C++; see file luaconf.h.) When Lua faces any error (such as memory allocation errors, type errors, syntax errors, and runtime errors) it raises an error; that is, it does a long jump. A protected environment uses setjmp to set a recover point; any error jumps to the most recent active recover point.

Most functions in the API can throw an error, for instance due to a memory allocation error. The documentation for each function indicates whether it can throw errors.

Inside a C function you can throw an error by calling lua_error.

3.7 - Functions and Types

Here we list all functions and types from the C API in alphabetical order. Each function has an indicator like this: [-o, +p, x]

The first field, o, is how many elements the function pops from the stack. The second field, p, is how many elements the function pushes onto the stack. (Any function always pushes its results after popping its arguments.) A field in the form x|y means the function can push (or pop) x or y elements, depending on the situation; an interrogation mark '?' means that we cannot know how many elements the function pops/pushes by looking only at its arguments (e.g., they may depend on what is on the stack). The third field, x, tells whether the function may throw errors: '-' means the function never throws any error; 'm' means the function may throw an error only due to not enough memory; 'e' means the function may throw other kinds of errors; 'v' means the function may throw an error on purpose.

lua_Alloc

typedef void * (*lua_Alloc) (void *ud,
                             void *ptr,
                             size_t osize,
                             size_t nsize);

The type of the memory-allocation function used by Lua states. The allocator function must provide a functionality similar to realloc, but not exactly the same. Its arguments are ud, an opaque pointer passed to lua_newstate; ptr, a pointer to the block being allocated/reallocated/freed; osize, the original size of the block; nsize, the new size of the block. ptr is NULL if and only if osize is zero. When nsize is zero, the allocator must return NULL; if osize is not zero, it should free the block pointed to by ptr. When nsize is not zero, the allocator returns NULL if and only if it cannot fill the request. When nsize is not zero and osize is zero, the allocator should behave like malloc. When nsize and osize are not zero, the allocator behaves like realloc. Lua assumes that the allocator never fails when osize >= nsize.

Here is a simple implementation for the allocator function. It is used in the auxiliary library by luaL_newstate. 

     static void *l_alloc (void *ud, void *ptr, size_t osize,
                                                size_t nsize) {
       (void)ud;  (void)osize;  /* not used */
       if (nsize == 0) {
         free(ptr);
         return NULL;
       }
       else
         return realloc(ptr, nsize);
     }

This code assumes that free(NULL) has no effect and that realloc(NULL, size) is equivalent to malloc(size). ANSI C ensures both behaviors.

lua_atpanic

[-0, +0, -] 

lua_CFunction lua_atpanic (lua_State *L, lua_CFunction panicf);

Sets a new panic function and returns the old one.

If an error happens outside any protected environment, Lua calls a panic function and then calls exit(EXIT_FAILURE), thus exiting the host application. Your panic function can avoid this exit by never returning (e.g., doing a long jump).

The panic function can access the error message at the top of the stack.

lua_call

[-(nargs + 1), +nresults, e] 

void lua_call (lua_State *L, int nargs, int nresults);

Calls a function.

To call a function you must use the following protocol: first, the function to be called is pushed onto the stack; then, the arguments to the function are pushed in direct order; that is, the first argument is pushed first. Finally you call lua_call; nargs is the number of arguments that you pushed onto the stack. All arguments and the function value are popped from the stack when the function is called. The function results are pushed onto the stack when the function returns. The number of results is adjusted to nresults, unless nresults is LUA_MULTRET. In this case, all results from the function are pushed. Lua takes care that the returned values fit into the stack space. The function results are pushed onto the stack in direct order (the first result is pushed first), so that after the call the last result is on the top of the stack.

Any error inside the called function is propagated upwards (with a longjmp).

The following example shows how the host program can do the equivalent to this Lua code: 

     a = f("how", t.x, 14)

Here it is in C: 

     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
     lua_pushstring(L, "how");                        /* 1st argument */
     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
     lua_remove(L, -2);                  /* remove 't' from the stack */
     lua_pushinteger(L, 14);                          /* 3rd argument */
     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */

Note that the code above is "balanced": at its end, the stack is back to its original configuration. This is considered good programming practice.

lua_CFunction

typedef int (*lua_CFunction) (lua_State *L);

Type for C functions.

In order to communicate properly with Lua, a C function must use the following protocol, which defines the way parameters and results are passed: a C function receives its arguments from Lua in its stack in direct order (the first argument is pushed first). So, when the function starts, lua_gettop(L) returns the number of arguments received by the function. The first argument (if any) is at index 1 and its last argument is at index lua_gettop(L). To return values to Lua, a C function just pushes them onto the stack, in direct order (the first result is pushed first), and returns the number of results. Any other value in the stack below the results will be properly discarded by Lua. Like a Lua function, a C function called by Lua can also return many results.

As an example, the following function receives a variable number of numerical arguments and returns their average and sum: 

     static int foo (lua_State *L) {
       int n = lua_gettop(L);    /* number of arguments */
       lua_Number sum = 0;
       int i;
       for (i = 1; i <= n; i++) {
         if (!lua_isnumber(L, i)) {
           lua_pushstring(L, "incorrect argument");
           lua_error(L);
         }
         sum += lua_tonumber(L, i);
       }
       lua_pushnumber(L, sum/n);        /* first result */
       lua_pushnumber(L, sum);         /* second result */
       return 2;                   /* number of results */
     }

lua_checkstack

[-0, +0, m] 

int lua_checkstack (lua_State *L, int extra);

Ensures that there are at least extra free stack slots in the stack. It returns false if it cannot grow the stack to that size. This function never shrinks the stack; if the stack is already larger than the new size, it is left unchanged.

lua_close

[-0, +0, -] 

void lua_close (lua_State *L);

Destroys all objects in the given Lua state (calling the corresponding garbage-collection metamethods, if any) and frees all dynamic memory used by this state. On several platforms, you may not need to call this function, because all resources are naturally released when the host program ends. On the other hand, long-running programs, such as a daemon or a web server, might need to release states as soon as they are not needed, to avoid growing too large.

lua_concat

[-n, +1, e] 

void lua_concat (lua_State *L, int n);

Concatenates the n values at the top of the stack, pops them, and leaves the result at the top. If n is 1, the result is the single value on the stack (that is, the function does nothing); if n is 0, the result is the empty string. Concatenation is performed following the usual semantics of Lua (see §2.5.4).

lua_cpcall

[-0, +(0|1), -] 

int lua_cpcall (lua_State *L, lua_CFunction func, void *ud);

Calls the C function func in protected mode. func starts with only one element in its stack, a light userdata containing ud. In case of errors, lua_cpcall returns the same error codes as lua_pcall, plus the error object on the top of the stack; otherwise, it returns zero, and does not change the stack. All values returned by func are discarded.

lua_createtable

[-0, +1, m] 

void lua_createtable (lua_State *L, int narr, int nrec);

Creates a new empty table and pushes it onto the stack. The new table has space pre-allocated for narr array elements and nrec non-array elements. This pre-allocation is useful when you know exactly how many elements the table will have. Otherwise you can use the function lua_newtable.

lua_dump

[-0, +0, m] 

int lua_dump (lua_State *L, lua_Writer writer, void *data);

Dumps a function as a binary chunk. Receives a Lua function on the top of the stack and produces a binary chunk that, if loaded again, results in a function equivalent to the one dumped. As it produces parts of the chunk, lua_dump calls function writer (see lua_Writer) with the given data to write them.

The value returned is the error code returned by the last call to the writer; 0 means no errors.

This function does not pop the Lua function from the stack.

lua_equal

[-0, +0, e] 

int lua_equal (lua_State *L, int index1, int index2);

Returns 1 if the two values in acceptable indices index1 and index2 are equal, following the semantics of the Lua == operator (that is, may call metamethods). Otherwise returns 0. Also returns 0 if any of the indices is non valid.

lua_error

[-1, +0, v] 

int lua_error (lua_State *L);

Generates a Lua error. The error message (which can actually be a Lua value of any type) must be on the stack top. This function does a long jump, and therefore never returns. (see luaL_error).

lua_gc

[-0, +0, e] 

int lua_gc (lua_State *L, int what, int data);

Controls the garbage collector.

This function performs several tasks, according to the value of the parameter what:

  • LUA_GCSTOP: stops the garbage collector.
  • LUA_GCRESTART: restarts the garbage collector.
  • LUA_GCCOLLECT: performs a full garbage-collection cycle.
  • LUA_GCCOUNT: returns the current amount of memory (in Kbytes) in use by Lua.
  • LUA_GCCOUNTB: returns the remainder of dividing the current amount of bytes of memory in use by Lua by 1024.
  • LUA_GCSTEP: performs an incremental step of garbage collection. The step "size" is controlled by data (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of data. The function returns 1 if the step finished a garbage-collection cycle.
  • LUA_GCSETPAUSE: sets data as the new value for the pause of the collector (see §2.10). The function returns the previous value of the pause.
  • LUA_GCSETSTEPMUL: sets data as the new value for the step multiplier of the collector (see §2.10). The function returns the previous value of the step multiplier.

lua_getallocf

[-0, +0, -] 

lua_Alloc lua_getallocf (lua_State *L, void **ud);

Returns the memory-allocation function of a given state. If ud is not NULL, Lua stores in *ud the opaque pointer passed to lua_newstate.

lua_getfenv

[-0, +1, -] 

void lua_getfenv (lua_State *L, int index);

Pushes onto the stack the environment table of the value at the given index.

lua_getfield

[-0, +1, e] 

void lua_getfield (lua_State *L, int index, const char *k);

Pushes onto the stack the value t[k], where t is the value at the given valid index. As in Lua, this function may trigger a metamethod for the "index" event (see §2.8).

lua_getglobal

[-0, +1, e] 

void lua_getglobal (lua_State *L, const char *name);

Pushes onto the stack the value of the global name. It is defined as a macro: 

     #define lua_getglobal(L,s)  lua_getfield(L, LUA_GLOBALSINDEX, s)

lua_getmetatable

[-0, +(0|1), -] 

int lua_getmetatable (lua_State *L, int index);

Pushes onto the stack the metatable of the value at the given acceptable index. If the index is not valid, or if the value does not have a metatable, the function returns 0 and pushes nothing on the stack.

lua_gettable

[-1, +1, e] 

void lua_gettable (lua_State *L, int index);

Pushes onto the stack the value t[k], where t is the value at the given valid index and k is the value at the top of the stack.

This function pops the key from the stack (putting the resulting value in its place). As in Lua, this function may trigger a metamethod for the "index" event (see §2.8).

lua_gettop

[-0, +0, -] 

int lua_gettop (lua_State *L);

Returns the index of the top element in the stack. Because indices start at 1, this result is equal to the number of elements in the stack (and so 0 means an empty stack).

lua_insert

[-1, +1, -] 

void lua_insert (lua_State *L, int index);

Moves the top element into the given valid index, shifting up the elements above this index to open space. Cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.

lua_Integer

typedef ptrdiff_t lua_Integer;

The type used by the Lua API to represent integral values.

By default it is a ptrdiff_t, which is usually the largest signed integral type the machine handles "comfortably".

lua_isboolean

[-0, +0, -] 

int lua_isboolean (lua_State *L, int index);

Returns 1 if the value at the given acceptable index has type boolean, and 0 otherwise.

lua_iscfunction

[-0, +0, -] 

int lua_iscfunction (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a C function, and 0 otherwise.

lua_isfunction

[-0, +0, -] 

int lua_isfunction (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a function (either C or Lua), and 0 otherwise.

lua_islightuserdata

[-0, +0, -] 

int lua_islightuserdata (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a light userdata, and 0 otherwise.

lua_isnil

[-0, +0, -] 

int lua_isnil (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is nil, and 0 otherwise.

lua_isnone

[-0, +0, -] 

int lua_isnone (lua_State *L, int index);

Returns 1 if the given acceptable index is not valid (that is, it refers to an element outside the current stack), and 0 otherwise.

lua_isnoneornil

[-0, +0, -] 

int lua_isnoneornil (lua_State *L, int index);

Returns 1 if the given acceptable index is not valid (that is, it refers to an element outside the current stack) or if the value at this index is nil, and 0 otherwise.

lua_isnumber

[-0, +0, -] 

int lua_isnumber (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a number or a string convertible to a number, and 0 otherwise.

lua_isstring

[-0, +0, -] 

int lua_isstring (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a string or a number (which is always convertible to a string), and 0 otherwise.

lua_istable

[-0, +0, -] 

int lua_istable (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a table, and 0 otherwise.

lua_isthread

[-0, +0, -] 

int lua_isthread (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a thread, and 0 otherwise.

lua_isuserdata

[-0, +0, -] 

int lua_isuserdata (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a userdata (either full or light), and 0 otherwise.

lua_lessthan

[-0, +0, e] 

int lua_lessthan (lua_State *L, int index1, int index2);

Returns 1 if the value at acceptable index index1 is smaller than the value at acceptable index index2, following the semantics of the Lua < operator (that is, may call metamethods). Otherwise returns 0. Also returns 0 if any of the indices is non valid.

lua_load

[-0, +1, -] 

int lua_load (lua_State *L,
              lua_Reader reader,
              void *data,
              const char *chunkname);

Loads a Lua chunk. If there are no errors, lua_load pushes the compiled chunk as a Lua function on top of the stack. Otherwise, it pushes an error message. The return values of lua_load are:

This function only loads a chunk; it does not run it.

lua_load automatically detects whether the chunk is text or binary, and loads it accordingly (see program luac).

The lua_load function uses a user-supplied reader function to read the chunk (see lua_Reader). The data argument is an opaque value passed to the reader function.

The chunkname argument gives a name to the chunk, which is used for error messages and in debug information (see §3.8).

lua_newstate

[-0, +0, -] 

lua_State *lua_newstate (lua_Alloc f, void *ud);

Creates a new, independent state. Returns NULL if cannot create the state (due to lack of memory). The argument f is the allocator function; Lua does all memory allocation for this state through this function. The second argument, ud, is an opaque pointer that Lua simply passes to the allocator in every call.

lua_newtable

[-0, +1, m] 

void lua_newtable (lua_State *L);

Creates a new empty table and pushes it onto the stack. It is equivalent to lua_createtable(L, 0, 0).

lua_newthread

[-0, +1, m] 

lua_State *lua_newthread (lua_State *L);

Creates a new thread, pushes it on the stack, and returns a pointer to a lua_State that represents this new thread. The new state returned by this function shares with the original state all global objects (such as tables), but has an independent execution stack.

There is no explicit function to close or to destroy a thread. Threads are subject to garbage collection, like any Lua object.

lua_newuserdata

[-0, +1, m] 

void *lua_newuserdata (lua_State *L, size_t size);

This function allocates a new block of memory with the given size, pushes onto the stack a new full userdata with the block address, and returns this address.

Userdata represent C values in Lua. A full userdata represents a block of memory. It is an object (like a table): you must create it, it can have its own metatable, and you can detect when it is being collected. A full userdata is only equal to itself (under raw equality).

When Lua collects a full userdata with a gc metamethod, Lua calls the metamethod and marks the userdata as finalized. When this userdata is collected again then Lua frees its corresponding memory.

lua_next

[-1, +(2|0), e] 

int lua_next (lua_State *L, int index);

Pops a key from the stack, and pushes a key-value pair from the table at the given index (the "next" pair after the given key). If there are no more elements in the table, then lua_next returns 0 (and pushes nothing).

A typical traversal looks like this: 

     /* table is in the stack at index 't' */
     lua_pushnil(L);  /* first key */
     while (lua_next(L, t) != 0) {
       /* uses 'key' (at index -2) and 'value' (at index -1) */
       printf("%s - %s\n",
              lua_typename(L, lua_type(L, -2)),
              lua_typename(L, lua_type(L, -1)));
       /* removes 'value'; keeps 'key' for next iteration */
       lua_pop(L, 1);
     }

While traversing a table, do not call lua_tolstring directly on a key, unless you know that the key is actually a string. Recall that lua_tolstring changes the value at the given index; this confuses the next call to lua_next.

lua_Number

typedef double lua_Number;

The type of numbers in Lua. By default, it is double, but that can be changed in luaconf.h.

Through the configuration file you can change Lua to operate with another type for numbers (e.g., float or long).

lua_objlen

[-0, +0, -] 

size_t lua_objlen (lua_State *L, int index);

Returns the "length" of the value at the given acceptable index: for strings, this is the string length; for tables, this is the result of the length operator ('#'); for userdata, this is the size of the block of memory allocated for the userdata; for other values, it is 0.

lua_pcall

[-(nargs + 1), +(nresults|1), -] 

int lua_pcall (lua_State *L, int nargs, int nresults, int errfunc);

Calls a function in protected mode.

Both nargs and nresults have the same meaning as in lua_call. If there are no errors during the call, lua_pcall behaves exactly like lua_call. However, if there is any error, lua_pcall catches it, pushes a single value on the stack (the error message), and returns an error code. Like lua_call, lua_pcall always removes the function and its arguments from the stack.

If errfunc is 0, then the error message returned on the stack is exactly the original error message. Otherwise, errfunc is the stack index of an error handler function. (In the current implementation, this index cannot be a pseudo-index.) In case of runtime errors, this function will be called with the error message and its return value will be the message returned on the stack by lua_pcall.

Typically, the error handler function is used to add more debug information to the error message, such as a stack traceback. Such information cannot be gathered after the return of lua_pcall, since by then the stack has unwound.

The lua_pcall function returns 0 in case of success or one of the following error codes (defined in lua.h):

  • LUA_ERRRUN: a runtime error.
  • LUA_ERRMEM: memory allocation error. For such errors, Lua does not call the error handler function.
  • LUA_ERRERR: error while running the error handler function.

lua_pop

[-n, +0, -] 

void lua_pop (lua_State *L, int n);

Pops n elements from the stack.

lua_pushboolean

[-0, +1, -] 

void lua_pushboolean (lua_State *L, int b);

Pushes a boolean value with value b onto the stack.

lua_pushcclosure

[-n, +1, m] 

void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);

Pushes a new C closure onto the stack.

When a C function is created, it is possible to associate some values with it, thus creating a C closure (see §3.4); these values are then accessible to the function whenever it is called. To associate values with a C function, first these values should be pushed onto the stack (when there are multiple values, the first value is pushed first). Then lua_pushcclosure is called to create and push the C function onto the stack, with the argument n telling how many values should be associated with the function. lua_pushcclosure also pops these values from the stack.

The maximum value for n is 255.

lua_pushcfunction

[-0, +1, m] 

void lua_pushcfunction (lua_State *L, lua_CFunction f);

Pushes a C function onto the stack. This function receives a pointer to a C function and pushes onto the stack a Lua value of type function that, when called, invokes the corresponding C function.

Any function to be registered in Lua must follow the correct protocol to receive its parameters and return its results (see lua_CFunction).

lua_pushcfunction is defined as a macro: 

     #define lua_pushcfunction(L,f)  lua_pushcclosure(L,f,0)

lua_pushfstring

[-0, +1, m] 

const char *lua_pushfstring (lua_State *L, const char *fmt, ...);

Pushes onto the stack a formatted string and returns a pointer to this string. It is similar to the C function sprintf, but has some important differences:

  • You do not have to allocate space for the result: the result is a Lua string and Lua takes care of memory allocation (and deallocation, through garbage collection).
  • The conversion specifiers are quite restricted. There are no flags, widths, or precisions. The conversion specifiers can only be '%%' (inserts a '%' in the string), '%s' (inserts a zero-terminated string, with no size restrictions), '%f' (inserts a lua_Number), '%p' (inserts a pointer as a hexadecimal numeral), '%d' (inserts an int), and '%c' (inserts an int as a character).

lua_pushinteger

[-0, +1, -] 

void lua_pushinteger (lua_State *L, lua_Integer n);

Pushes a number with value n onto the stack.

lua_pushlightuserdata

[-0, +1, -] 

void lua_pushlightuserdata (lua_State *L, void *p);

Pushes a light userdata onto the stack.

Userdata represent C values in Lua. A light userdata represents a pointer. It is a value (like a number): you do not create it, it has no individual metatable, and it is not collected (as it was never created). A light userdata is equal to "any" light userdata with the same C address.

lua_pushliteral

[-0, +1, m] 

void lua_pushliteral (lua_State *L, const char *s);

This macro is equivalent to lua_pushlstring, but can be used only when s is a literal string. In these cases, it automatically provides the string length.

lua_pushlstring

[-0, +1, m] 

void lua_pushlstring (lua_State *L, const char *s, size_t len);

Pushes the string pointed to by s with size len onto the stack. Lua makes (or reuses) an internal copy of the given string, so the memory at s can be freed or reused immediately after the function returns. The string can contain embedded zeros.

lua_pushnil

[-0, +1, -] 

void lua_pushnil (lua_State *L);

Pushes a nil value onto the stack.

lua_pushnumber

[-0, +1, -] 

void lua_pushnumber (lua_State *L, lua_Number n);

Pushes a number with value n onto the stack.

lua_pushstring

[-0, +1, m] 

void lua_pushstring (lua_State *L, const char *s);

Pushes the zero-terminated string pointed to by s onto the stack. Lua makes (or reuses) an internal copy of the given string, so the memory at s can be freed or reused immediately after the function returns. The string cannot contain embedded zeros; it is assumed to end at the first zero.

lua_pushthread

[-0, +1, -] 

int lua_pushthread (lua_State *L);

Pushes the thread represented by L onto the stack. Returns 1 if this thread is the main thread of its state.

lua_pushvalue

[-0, +1, -] 

void lua_pushvalue (lua_State *L, int index);

Pushes a copy of the element at the given valid index onto the stack.

lua_pushvfstring

[-0, +1, m] 

const char *lua_pushvfstring (lua_State *L,
                              const char *fmt,
                              va_list argp);

Equivalent to lua_pushfstring, except that it receives a va_list instead of a variable number of arguments.

lua_rawequal

[-0, +0, -] 

int lua_rawequal (lua_State *L, int index1, int index2);

Returns 1 if the two values in acceptable indices index1 and index2 are primitively equal (that is, without calling metamethods). Otherwise returns 0. Also returns 0 if any of the indices are non valid.

lua_rawget

[-1, +1, -] 

void lua_rawget (lua_State *L, int index);

Similar to lua_gettable, but does a raw access (i.e., without metamethods).

lua_rawgeti

[-0, +1, -] 

void lua_rawgeti (lua_State *L, int index, int n);

Pushes onto the stack the value t[n], where t is the value at the given valid index. The access is raw; that is, it does not invoke metamethods.

lua_rawset

[-2, +0, m] 

void lua_rawset (lua_State *L, int index);

Similar to lua_settable, but does a raw assignment (i.e., without metamethods).

lua_rawseti

[-1, +0, m] 

void lua_rawseti (lua_State *L, int index, int n);

Does the equivalent of t[n] = v, where t is the value at the given valid index and v is the value at the top of the stack.

This function pops the value from the stack. The assignment is raw; that is, it does not invoke metamethods.

lua_Reader

typedef const char * (*lua_Reader) (lua_State *L,
                                    void *data,
                                    size_t *size);

The reader function used by lua_load. Every time it needs another piece of the chunk, lua_load calls the reader, passing along its data parameter. The reader must return a pointer to a block of memory with a new piece of the chunk and set size to the block size. The block must exist until the reader function is called again. To signal the end of the chunk, the reader must return NULL or set size to zero. The reader function may return pieces of any size greater than zero.

lua_register

[-0, +0, e] 

void lua_register (lua_State *L,
                   const char *name,
                   lua_CFunction f);

Sets the C function f as the new value of global name. It is defined as a macro: 

     #define lua_register(L,n,f) \
            (lua_pushcfunction(L, f), lua_setglobal(L, n))

lua_remove

[-1, +0, -] 

void lua_remove (lua_State *L, int index);

Removes the element at the given valid index, shifting down the elements above this index to fill the gap. Cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.

lua_replace

[-1, +0, -] 

void lua_replace (lua_State *L, int index);

Moves the top element into the given position (and pops it), without shifting any element (therefore replacing the value at the given position).

lua_resume

[-?, +?, -] 

int lua_resume (lua_State *L, int narg);

Starts and resumes a coroutine in a given thread.

To start a coroutine, you first create a new thread (see lua_newthread); then you push onto its stack the main function plus any arguments; then you call lua_resume, with narg being the number of arguments. This call returns when the coroutine suspends or finishes its execution. When it returns, the stack contains all values passed to lua_yield, or all values returned by the body function. lua_resume returns LUA_YIELD if the coroutine yields, 0 if the coroutine finishes its execution without errors, or an error code in case of errors (see lua_pcall). In case of errors, the stack is not unwound, so you can use the debug API over it. The error message is on the top of the stack. To restart a coroutine, you put on its stack only the values to be passed as results from yield, and then call lua_resume.

lua_setallocf

[-0, +0, -] 

void lua_setallocf (lua_State *L, lua_Alloc f, void *ud);

Changes the allocator function of a given state to f with user data ud.

lua_setfenv

[-1, +0, -] 

int lua_setfenv (lua_State *L, int index);

Pops a table from the stack and sets it as the new environment for the value at the given index. If the value at the given index is neither a function nor a thread nor a userdata, lua_setfenv returns 0. Otherwise it returns 1.

lua_setfield

[-1, +0, e] 

void lua_setfield (lua_State *L, int index, const char *k);

Does the equivalent to t[k] = v, where t is the value at the given valid index and v is the value at the top of the stack.

This function pops the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event (see §2.8).

lua_setglobal

[-1, +0, e] 

void lua_setglobal (lua_State *L, const char *name);

Pops a value from the stack and sets it as the new value of global name. It is defined as a macro: 

     #define lua_setglobal(L,s)   lua_setfield(L, LUA_GLOBALSINDEX, s)

lua_setmetatable

[-1, +0, -] 

int lua_setmetatable (lua_State *L, int index);

Pops a table from the stack and sets it as the new metatable for the value at the given acceptable index.

lua_settable

[-2, +0, e] 

void lua_settable (lua_State *L, int index);

Does the equivalent to t[k] = v, where t is the value at the given valid index, v is the value at the top of the stack, and k is the value just below the top.

This function pops both the key and the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event (see §2.8).

lua_settop

[-?, +?, -] 

void lua_settop (lua_State *L, int index);

Accepts any acceptable index, or 0, and sets the stack top to this index. If the new top is larger than the old one, then the new elements are filled with nil. If index is 0, then all stack elements are removed.

lua_State

typedef struct lua_State lua_State;

Opaque structure that keeps the whole state of a Lua interpreter. The Lua library is fully reentrant: it has no global variables. All information about a state is kept in this structure.

A pointer to this state must be passed as the first argument to every function in the library, except to lua_newstate, which creates a Lua state from scratch.

lua_status

[-0, +0, -] 

int lua_status (lua_State *L);

Returns the status of the thread L.

The status can be 0 for a normal thread, an error code if the thread finished its execution with an error, or LUA_YIELD if the thread is suspended.

lua_toboolean

[-0, +0, -] 

int lua_toboolean (lua_State *L, int index);

Converts the Lua value at the given acceptable index to a C boolean value (0 or 1). Like all tests in Lua, lua_toboolean returns 1 for any Lua value different from false and nil; otherwise it returns 0. It also returns 0 when called with a non-valid index. (If you want to accept only actual boolean values, use lua_isboolean to test the value's type.)

lua_tocfunction

[-0, +0, -] 

lua_CFunction lua_tocfunction (lua_State *L, int index);

Converts a value at the given acceptable index to a C function. That value must be a C function; otherwise, returns NULL.

lua_tointeger

[-0, +0, -] 

lua_Integer lua_tointeger (lua_State *L, int index);

Converts the Lua value at the given acceptable index to the signed integral type lua_Integer. The Lua value must be a number or a string convertible to a number (see §2.2.1); otherwise, lua_tointeger returns 0.

If the number is not an integer, it is truncated in some non-specified way.

lua_tolstring

[-0, +0, m] 

const char *lua_tolstring (lua_State *L, int index, size_t *len);

Converts the Lua value at the given acceptable index to a C string. If len is not NULL, it also sets *len with the string length. The Lua value must be a string or a number; otherwise, the function returns NULL. If the value is a number, then lua_tolstring also changes the actual value in the stack to a string. (This change confuses lua_next when lua_tolstring is applied to keys during a table traversal.)

lua_tolstring returns a fully aligned pointer to a string inside the Lua state. This string always has a zero ('\0') after its last character (as in C), but can contain other zeros in its body. Because Lua has garbage collection, there is no guarantee that the pointer returned by lua_tolstring will be valid after the corresponding value is removed from the stack.

lua_tonumber

[-0, +0, -] 

lua_Number lua_tonumber (lua_State *L, int index);

Converts the Lua value at the given acceptable index to the C type lua_Number (see lua_Number). The Lua value must be a number or a string convertible to a number (see §2.2.1); otherwise, lua_tonumber returns 0.

lua_topointer

[-0, +0, -] 

const void *lua_topointer (lua_State *L, int index);

Converts the value at the given acceptable index to a generic C pointer (void*). The value can be a userdata, a table, a thread, or a function; otherwise, lua_topointer returns NULL. Different objects will give different pointers. There is no way to convert the pointer back to its original value.

Typically this function is used only for debug information.

lua_tostring

[-0, +0, m] 

const char *lua_tostring (lua_State *L, int index);

Equivalent to lua_tolstring with len equal to NULL.

lua_tothread

[-0, +0, -] 

lua_State *lua_tothread (lua_State *L, int index);

Converts the value at the given acceptable index to a Lua thread (represented as lua_State*). This value must be a thread; otherwise, the function returns NULL.

lua_touserdata

[-0, +0, -] 

void *lua_touserdata (lua_State *L, int index);

If the value at the given acceptable index is a full userdata, returns its block address. If the value is a light userdata, returns its pointer. Otherwise, returns NULL.

lua_type

[-0, +0, -] 

int lua_type (lua_State *L, int index);

Returns the type of the value in the given acceptable index, or LUA_TNONE for a non-valid index (that is, an index to an "empty" stack position). The types returned by lua_type are coded by the following constants defined in lua.h: LUA_TNIL, LUA_TNUMBER, LUA_TBOOLEAN, LUA_TSTRING, LUA_TTABLE, LUA_TFUNCTION, LUA_TUSERDATA, LUA_TTHREAD, and LUA_TLIGHTUSERDATA.

lua_typename

[-0, +0, -] 

const char *lua_typename  (lua_State *L, int tp);

Returns the name of the type encoded by the value tp, which must be one the values returned by lua_type.

lua_Writer

typedef int (*lua_Writer) (lua_State *L,
                           const void* p,
                           size_t sz,
                           void* ud);

The type of the writer function used by lua_dump. Every time it produces another piece of chunk, lua_dump calls the writer, passing along the buffer to be written (p), its size (sz), and the data parameter supplied to lua_dump.

The writer returns an error code: 0 means no errors; any other value means an error and stops lua_dump from calling the writer again.

lua_xmove

[-?, +?, -] 

void lua_xmove (lua_State *from, lua_State *to, int n);

Exchange values between different threads of the same global state.

This function pops n values from the stack from, and pushes them onto the stack to.

lua_yield

[-?, +?, -] 

int lua_yield  (lua_State *L, int nresults);

Yields a coroutine.

This function should only be called as the return expression of a C function, as follows: 

     return lua_yield (L, nresults);

When a C function calls lua_yield in that way, the running coroutine suspends its execution, and the call to lua_resume that started this coroutine returns. The parameter nresults is the number of values from the stack that are passed as results to lua_resume.

3.8 - The Debug Interface

Lua has no built-in debugging facilities. Instead, it offers a special interface by means of functions and hooks. This interface allows the construction of different kinds of debuggers, profilers, and other tools that need "inside information" from the interpreter.

lua_Debug

typedef struct lua_Debug {
  int event;
  const char *name;           /* (n) */
  const char *namewhat;       /* (n) */
  const char *what;           /* (S) */
  const char *source;         /* (S) */
  int currentline;            /* (l) */
  int nups;                   /* (u) number of upvalues */
  int linedefined;            /* (S) */
  int lastlinedefined;        /* (S) */
  char short_src[LUA_IDSIZE]; /* (S) */
  /* private part */
  other fields
} lua_Debug;

A structure used to carry different pieces of information about an active function. lua_getstack fills only the private part of this structure, for later use. To fill the other fields of lua_Debug with useful information, call lua_getinfo.

The fields of lua_Debug have the following meaning:

  • source: If the function was defined in a string, then source is that string. If the function was defined in a file, then source starts with a '@' followed by the file name.
  • short_src: a "printable" version of source, to be used in error messages.
  • linedefined: the line number where the definition of the function starts.
  • lastlinedefined: the line number where the definition of the function ends.
  • what: the string "Lua" if the function is a Lua function, "C" if it is a C function, "main" if it is the main part of a chunk, and "tail" if it was a function that did a tail call. In the latter case, Lua has no other information about the function.
  • currentline: the current line where the given function is executing. When no line information is available, currentline is set to -1.
  • name: a reasonable name for the given function. Because functions in Lua are first-class values, they do not have a fixed name: some functions can be the value of multiple global variables, while others can be stored only in a table field. The lua_getinfo function checks how the function was called to find a suitable name. If it cannot find a name, then name is set to NULL.
  • namewhat: explains the name field. The value of namewhat can be "global", "local", "method", "field", "upvalue", or "" (the empty string), according to how the function was called. (Lua uses the empty string when no other option seems to apply.)
  • nups: the number of upvalues of the function.

lua_gethook

[-0, +0, -] 

lua_Hook lua_gethook (lua_State *L);

Returns the current hook function.

lua_gethookcount

[-0, +0, -] 

int lua_gethookcount (lua_State *L);

Returns the current hook count.

lua_gethookmask

[-0, +0, -] 

int lua_gethookmask (lua_State *L);

Returns the current hook mask.

lua_getinfo

[-(0|1), +(0|1|2), m] 

int lua_getinfo (lua_State *L, const char *what, lua_Debug *ar);

Returns information about a specific function or function invocation.

To get information about a function invocation, the parameter ar must be a valid activation record that was filled by a previous call to lua_getstack or given as argument to a hook (see lua_Hook).

To get information about a function you push it onto the stack and start the what string with the character '>'. (In that case, lua_getinfo pops the function in the top of the stack.) For instance, to know in which line a function f was defined, you can write the following code: 

     lua_Debug ar;
     lua_getfield(L, LUA_GLOBALSINDEX, "f");  /* get global 'f' */
     lua_getinfo(L, ">S", &ar);
     printf("%d\n", ar.linedefined);

Each character in the string what selects some fields of the structure ar to be filled or a value to be pushed on the stack:

  • 'n': fills in the field name and namewhat;
  • 'S': fills in the fields source, short_src, linedefined, lastlinedefined, and what;
  • 'l': fills in the field currentline;
  • 'u': fills in the field nups;
  • 'f': pushes onto the stack the function that is running at the given level;
  • 'L': pushes onto the stack a table whose indices are the numbers of the lines that are valid on the function. (A valid line is a line with some associated code, that is, a line where you can put a break point. Non-valid lines include empty lines and comments.)

This function returns 0 on error (for instance, an invalid option in what).

lua_getlocal

[-0, +(0|1), -] 

const char *lua_getlocal (lua_State *L, lua_Debug *ar, int n);

Gets information about a local variable of a given activation record. The parameter ar must be a valid activation record that was filled by a previous call to lua_getstack or given as argument to a hook (see lua_Hook). The index n selects which local variable to inspect (1 is the first parameter or active local variable, and so on, until the last active local variable). lua_getlocal pushes the variable's value onto the stack and returns its name.

Variable names starting with '(' (open parentheses) represent internal variables (loop control variables, temporaries, and C function locals).

Returns NULL (and pushes nothing) when the index is greater than the number of active local variables.

lua_getstack

[-0, +0, -] 

int lua_getstack (lua_State *L, int level, lua_Debug *ar);

Get information about the interpreter runtime stack.

This function fills parts of a lua_Debug structure with an identification of the activation record of the function executing at a given level. Level 0 is the current running function, whereas level n+1 is the function that has called level n. When there are no errors, lua_getstack returns 1; when called with a level greater than the stack depth, it returns 0.

lua_getupvalue

[-0, +(0|1), -] 

const char *lua_getupvalue (lua_State *L, int funcindex, int n);

Gets information about a closure's upvalue. (For Lua functions, upvalues are the external local variables that the function uses, and that are consequently included in its closure.) lua_getupvalue gets the index n of an upvalue, pushes the upvalue's value onto the stack, and returns its name. funcindex points to the closure in the stack. (Upvalues have no particular order, as they are active through the whole function. So, they are numbered in an arbitrary order.)

Returns NULL (and pushes nothing) when the index is greater than the number of upvalues. For C functions, this function uses the empty string "" as a name for all upvalues.

lua_Hook

typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);

Type for debugging hook functions.

Whenever a hook is called, its ar argument has its field event set to the specific event that triggered the hook. Lua identifies these events with the following constants: LUA_HOOKCALL, LUA_HOOKRET, LUA_HOOKTAILRET, LUA_HOOKLINE, and LUA_HOOKCOUNT. Moreover, for line events, the field currentline is also set. To get the value of any other field in ar, the hook must call lua_getinfo. For return events, event can be LUA_HOOKRET, the normal value, or LUA_HOOKTAILRET. In the latter case, Lua is simulating a return from a function that did a tail call; in this case, it is useless to call lua_getinfo.

While Lua is running a hook, it disables other calls to hooks. Therefore, if a hook calls back Lua to execute a function or a chunk, this execution occurs without any calls to hooks.

lua_sethook

[-0, +0, -] 

int lua_sethook (lua_State *L, lua_Hook f, int mask, int count);

Sets the debugging hook function.

Argument f is the hook function. mask specifies on which events the hook will be called: it is formed by a bitwise or of the constants LUA_MASKCALL, LUA_MASKRET, LUA_MASKLINE, and LUA_MASKCOUNT. The count argument is only meaningful when the mask includes LUA_MASKCOUNT. For each event, the hook is called as explained below:

  • The call hook: is called when the interpreter calls a function. The hook is called just after Lua enters the new function, before the function gets its arguments.
  • The return hook: is called when the interpreter returns from a function. The hook is called just before Lua leaves the function. You have no access to the values to be returned by the function.
  • The line hook: is called when the interpreter is about to start the execution of a new line of code, or when it jumps back in the code (even to the same line). (This event only happens while Lua is executing a Lua function.)
  • The count hook: is called after the interpreter executes every count instructions. (This event only happens while Lua is executing a Lua function.)

A hook is disabled by setting mask to zero.

lua_setlocal

[-(0|1), +0, -] 

const char *lua_setlocal (lua_State *L, lua_Debug *ar, int n);

Sets the value of a local variable of a given activation record. Parameters ar and n are as in lua_getlocal (see lua_getlocal). lua_setlocal assigns the value at the top of the stack to the variable and returns its name. It also pops the value from the stack.

Returns NULL (and pops nothing) when the index is greater than the number of active local variables.

lua_setupvalue

[-(0|1), +0, -] 

const char *lua_setupvalue (lua_State *L, int funcindex, int n);

Sets the value of a closure's upvalue. It assigns the value at the top of the stack to the upvalue and returns its name. It also pops the value from the stack. Parameters funcindex and n are as in the lua_getupvalue (see lua_getupvalue).

Returns NULL (and pops nothing) when the index is greater than the number of upvalues.

4 - The Auxiliary Library

The auxiliary library provides several convenient functions to interface C with Lua. While the basic API provides the primitive functions for all interactions between C and Lua, the auxiliary library provides higher-level functions for some common tasks.

All functions from the auxiliary library are defined in header file lauxlib.h and have a prefix luaL_.

All functions in the auxiliary library are built on top of the basic API, and so they provide nothing that cannot be done with this API.

Several functions in the auxiliary library are used to check C function arguments. Their names are always luaL_check* or luaL_opt*. All of these functions throw an error if the check is not satisfied. Because the error message is formatted for arguments (e.g., "bad argument #1"), you should not use these functions for other stack values.

4.1 - Functions and Types

Here we list all functions and types from the auxiliary library in alphabetical order.

luaL_addchar

[-0, +0, m] 

void luaL_addchar (luaL_Buffer *B, char c);

Adds the character c to the buffer B (see luaL_Buffer).

luaL_addlstring

[-0, +0, m] 

void luaL_addlstring (luaL_Buffer *B, const char *s, size_t l);

Adds the string pointed to by s with length l to the buffer B (see luaL_Buffer). The string may contain embedded zeros.

luaL_addsize

[-0, +0, m] 

void luaL_addsize (luaL_Buffer *B, size_t n);

Adds to the buffer B (see luaL_Buffer) a string of length n previously copied to the buffer area (see luaL_prepbuffer).

luaL_addstring

[-0, +0, m] 

void luaL_addstring (luaL_Buffer *B, const char *s);

Adds the zero-terminated string pointed to by s to the buffer B (see luaL_Buffer). The string may not contain embedded zeros.

luaL_addvalue

[-1, +0, m] 

void luaL_addvalue (luaL_Buffer *B);

Adds the value at the top of the stack to the buffer B (see luaL_Buffer). Pops the value.

This is the only function on string buffers that can (and must) be called with an extra element on the stack, which is the value to be added to the buffer.

luaL_argcheck

[-0, +0, v] 

void luaL_argcheck (lua_State *L,
                    int cond,
                    int narg,
                    const char *extramsg);

Checks whether cond is true. If not, raises an error with the following message, where func is retrieved from the call stack: 

     bad argument #<narg> to <func> (<extramsg>)

luaL_argerror

[-0, +0, v] 

int luaL_argerror (lua_State *L, int narg, const char *extramsg);

Raises an error with the following message, where func is retrieved from the call stack: 

     bad argument #<narg> to <func> (<extramsg>)

This function never returns, but it is an idiom to use it in C functions as return luaL_argerror(args).

luaL_Buffer

typedef struct luaL_Buffer luaL_Buffer;

Type for a string buffer.

A string buffer allows C code to build Lua strings piecemeal. Its pattern of use is as follows:

  • First you declare a variable b of type luaL_Buffer.
  • Then you initialize it with a call luaL_buffinit(L, &b).
  • Then you add string pieces to the buffer calling any of the luaL_add* functions.
  • You finish by calling luaL_pushresult(&b). This call leaves the final string on the top of the stack.

During its normal operation, a string buffer uses a variable number of stack slots. So, while using a buffer, you cannot assume that you know where the top of the stack is. You can use the stack between successive calls to buffer operations as long as that use is balanced; that is, when you call a buffer operation, the stack is at the same level it was immediately after the previous buffer operation. (The only exception to this rule is luaL_addvalue.) After calling luaL_pushresult the stack is back to its level when the buffer was initialized, plus the final string on its top.

luaL_buffinit

[-0, +0, -] 

void luaL_buffinit (lua_State *L, luaL_Buffer *B);

Initializes a buffer B. This function does not allocate any space; the buffer must be declared as a variable (see luaL_Buffer).

luaL_callmeta

[-0, +(0|1), e] 

int luaL_callmeta (lua_State *L, int obj, const char *e);

Calls a metamethod.

If the object at index obj has a metatable and this metatable has a field e, this function calls this field and passes the object as its only argument. In this case this function returns 1 and pushes onto the stack the value returned by the call. If there is no metatable or no metamethod, this function returns 0 (without pushing any value on the stack).

luaL_checkany

[-0, +0, v] 

void luaL_checkany (lua_State *L, int narg);

Checks whether the function has an argument of any type (including nil) at position narg.

luaL_checkint

[-0, +0, v] 

int luaL_checkint (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to an int.

luaL_checkinteger

[-0, +0, v] 

lua_Integer luaL_checkinteger (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to a lua_Integer.

luaL_checklong

[-0, +0, v] 

long luaL_checklong (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to a long.

luaL_checklstring

[-0, +0, v] 

const char *luaL_checklstring (lua_State *L, int narg, size_t *l);

Checks whether the function argument narg is a string and returns this string; if l is not NULL fills *l with the string's length.

This function uses lua_tolstring to get its result, so all conversions and caveats of that function apply here.

luaL_checknumber

[-0, +0, v] 

lua_Number luaL_checknumber (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number.

luaL_checkoption

[-0, +0, v] 

int luaL_checkoption (lua_State *L,
                      int narg,
                      const char *def,
                      const char *const lst[]);

Checks whether the function argument narg is a string and searches for this string in the array lst (which must be NULL-terminated). Returns the index in the array where the string was found. Raises an error if the argument is not a string or if the string cannot be found.

If def is not NULL, the function uses def as a default value when there is no argument narg or if this argument is nil.

This is a useful function for mapping strings to C enums. (The usual convention in Lua libraries is to use strings instead of numbers to select options.)

luaL_checkstack

[-0, +0, v] 

void luaL_checkstack (lua_State *L, int sz, const char *msg);

Grows the stack size to top + sz elements, raising an error if the stack cannot grow to that size. msg is an additional text to go into the error message.

luaL_checkstring

[-0, +0, v] 

const char *luaL_checkstring (lua_State *L, int narg);

Checks whether the function argument narg is a string and returns this string.

This function uses lua_tolstring to get its result, so all conversions and caveats of that function apply here.

luaL_checktype

[-0, +0, v] 

void luaL_checktype (lua_State *L, int narg, int t);

Checks whether the function argument narg has type t. See lua_type for the encoding of types for t.

luaL_checkudata

[-0, +0, v] 

void *luaL_checkudata (lua_State *L, int narg, const char *tname);

Checks whether the function argument narg is a userdata of the type tname (see luaL_newmetatable).

luaL_dofile

[-0, +?, m] 

int luaL_dofile (lua_State *L, const char *filename);

Loads and runs the given file. It is defined as the following macro: 

     (luaL_loadfile(L, filename) || lua_pcall(L, 0, LUA_MULTRET, 0))

It returns 0 if there are no errors or 1 in case of errors.

luaL_dostring

[-0, +?, m] 

int luaL_dostring (lua_State *L, const char *str);

Loads and runs the given string. It is defined as the following macro: 

     (luaL_loadstring(L, str) || lua_pcall(L, 0, LUA_MULTRET, 0))

It returns 0 if there are no errors or 1 in case of errors.

luaL_error

[-0, +0, v] 

int luaL_error (lua_State *L, const char *fmt, ...);

Raises an error. The error message format is given by fmt plus any extra arguments, following the same rules of lua_pushfstring. It also adds at the beginning of the message the file name and the line number where the error occurred, if this information is available.

This function never returns, but it is an idiom to use it in C functions as return luaL_error(args).

luaL_getmetafield

[-0, +(0|1), m] 

int luaL_getmetafield (lua_State *L, int obj, const char *e);

Pushes onto the stack the field e from the metatable of the object at index obj. If the object does not have a metatable, or if the metatable does not have this field, returns 0 and pushes nothing.

luaL_getmetatable

[-0, +1, -] 

void luaL_getmetatable (lua_State *L, const char *tname);

Pushes onto the stack the metatable associated with name tname in the registry (see luaL_newmetatable).

luaL_gsub

[-0, +1, m] 

const char *luaL_gsub (lua_State *L,
                       const char *s,
                       const char *p,
                       const char *r);

Creates a copy of string s by replacing any occurrence of the string p with the string r. Pushes the resulting string on the stack and returns it.

luaL_loadbuffer

[-0, +1, m] 

int luaL_loadbuffer (lua_State *L,
                     const char *buff,
                     size_t sz,
                     const char *name);

Loads a buffer as a Lua chunk. This function uses lua_load to load the chunk in the buffer pointed to by buff with size sz.

This function returns the same results as lua_load. name is the chunk name, used for debug information and error messages.

luaL_loadfile

[-0, +1, m] 

int luaL_loadfile (lua_State *L, const char *filename);

Loads a file as a Lua chunk. This function uses lua_load to load the chunk in the file named filename. If filename is NULL, then it loads from the standard input. The first line in the file is ignored if it starts with a #.

This function returns the same results as lua_load, but it has an extra error code LUA_ERRFILE if it cannot open/read the file.

As lua_load, this function only loads the chunk; it does not run it.

luaL_loadstring

[-0, +1, m] 

int luaL_loadstring (lua_State *L, const char *s);

Loads a string as a Lua chunk. This function uses lua_load to load the chunk in the zero-terminated string s.

This function returns the same results as lua_load.

Also as lua_load, this function only loads the chunk; it does not run it.

luaL_newmetatable

[-0, +1, m] 

int luaL_newmetatable (lua_State *L, const char *tname);

If the registry already has the key tname, returns 0. Otherwise, creates a new table to be used as a metatable for userdata, adds it to the registry with key tname, and returns 1.

In both cases pushes onto the stack the final value associated with tname in the registry.

luaL_newstate

[-0, +0, -] 

lua_State *luaL_newstate (void);

Creates a new Lua state. It calls lua_newstate with an allocator based on the standard C realloc function and then sets a panic function (see lua_atpanic) that prints an error message to the standard error output in case of fatal errors.

Returns the new state, or NULL if there is a memory allocation error.

luaL_openlibs

[-0, +0, m] 

void luaL_openlibs (lua_State *L);

Opens all standard Lua libraries into the given state.

luaL_optint

[-0, +0, v] 

int luaL_optint (lua_State *L, int narg, int d);

If the function argument narg is a number, returns this number cast to an int. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optinteger

[-0, +0, v] 

lua_Integer luaL_optinteger (lua_State *L,
                             int narg,
                             lua_Integer d);

If the function argument narg is a number, returns this number cast to a lua_Integer. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optlong

[-0, +0, v] 

long luaL_optlong (lua_State *L, int narg, long d);

If the function argument narg is a number, returns this number cast to a long. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optlstring

[-0, +0, v] 

const char *luaL_optlstring (lua_State *L,
                             int narg,
                             const char *d,
                             size_t *l);

If the function argument narg is a string, returns this string. If this argument is absent or is nil, returns d. Otherwise, raises an error.

If l is not NULL, fills the position *l with the results's length.

luaL_optnumber

[-0, +0, v] 

lua_Number luaL_optnumber (lua_State *L, int narg, lua_Number d);

If the function argument narg is a number, returns this number. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optstring

[-0, +0, v] 

const char *luaL_optstring (lua_State *L,
                            int narg,
                            const char *d);

If the function argument narg is a string, returns this string. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_prepbuffer

[-0, +0, -] 

char *luaL_prepbuffer (luaL_Buffer *B);

Returns an address to a space of size LUAL_BUFFERSIZE where you can copy a string to be added to buffer B (see luaL_Buffer). After copying the string into this space you must call luaL_addsize with the size of the string to actually add it to the buffer.

luaL_pushresult

[-?, +1, m] 

void luaL_pushresult (luaL_Buffer *B);

Finishes the use of buffer B leaving the final string on the top of the stack.

luaL_ref

[-1, +0, m] 

int luaL_ref (lua_State *L, int t);

Creates and returns a reference, in the table at index t, for the object at the top of the stack (and pops the object).

A reference is a unique integer key. As long as you do not manually add integer keys into table t, luaL_ref ensures the uniqueness of the key it returns. You can retrieve an object referred by reference r by calling lua_rawgeti(L, t, r). Function luaL_unref frees a reference and its associated object.

If the object at the top of the stack is nil, luaL_ref returns the constant LUA_REFNIL. The constant LUA_NOREF is guaranteed to be different from any reference returned by luaL_ref.

luaL_Reg

typedef struct luaL_Reg {
  const char *name;
  lua_CFunction func;
} luaL_Reg;

Type for arrays of functions to be registered by luaL_register. name is the function name and func is a pointer to the function. Any array of luaL_Reg must end with an sentinel entry in which both name and func are NULL.

luaL_register

[-(0|1), +1, m] 

void luaL_register (lua_State *L,
                    const char *libname,
                    const luaL_Reg *l);

Opens a library.

When called with libname equal to NULL, it simply registers all functions in the list l (see luaL_Reg) into the table on the top of the stack.

When called with a non-null libname, luaL_register creates a new table t, sets it as the value of the global variable libname, sets it as the value of package.loaded[libname], and registers on it all functions in the list l. If there is a table in package.loaded[libname] or in variable libname, reuses this table instead of creating a new one.

In any case the function leaves the table on the top of the stack.

luaL_typename

[-0, +0, -] 

const char *luaL_typename (lua_State *L, int index);

Returns the name of the type of the value at the given index.

luaL_typerror

[-0, +0, v] 

int luaL_typerror (lua_State *L, int narg, const char *tname);

Generates an error with a message like the following: 

     location: bad argument narg to 'func' (tname expected, got rt)

where location is produced by luaL_where, func is the name of the current function, and rt is the type name of the actual argument.

luaL_unref

[-0, +0, -] 

void luaL_unref (lua_State *L, int t, int ref);

Releases reference ref from the table at index t (see luaL_ref). The entry is removed from the table, so that the referred object can be collected. The reference ref is also freed to be used again.

If ref is LUA_NOREF or LUA_REFNIL, luaL_unref does nothing.

luaL_where

[-0, +1, m] 

void luaL_where (lua_State *L, int lvl);

Pushes onto the stack a string identifying the current position of the control at level lvl in the call stack. Typically this string has the following format: 

     chunkname:currentline:

Level 0 is the running function, level 1 is the function that called the running function, etc.

This function is used to build a prefix for error messages.

5 - Standard Libraries

The standard Lua libraries provide useful functions that are implemented directly through the C API. Some of these functions provide essential services to the language (e.g., type and getmetatable); others provide access to "outside" services (e.g., I/O); and others could be implemented in Lua itself, but are quite useful or have critical performance requirements that deserve an implementation in C (e.g., table.sort).

All libraries are implemented through the official C API and are provided as separate C modules. Currently, Lua has the following standard libraries:

  • basic library, which includes the coroutine sub-library;
  • package library;
  • string manipulation;
  • table manipulation;
  • mathematical functions (sin, log, etc.);
  • input and output;
  • operating system facilities;
  • debug facilities.

Except for the basic and package libraries, each library provides all its functions as fields of a global table or as methods of its objects.

To have access to these libraries, the C host program should call the luaL_openlibs function, which opens all standard libraries. Alternatively, it can open them individually by calling luaopen_base (for the basic library), luaopen_package (for the package library), luaopen_string (for the string library), luaopen_table (for the table library), luaopen_math (for the mathematical library), luaopen_io (for the I/O library), luaopen_os (for the Operating System library), and luaopen_debug (for the debug library). These functions are declared in lualib.h and should not be called directly: you must call them like any other Lua C function, e.g., by using lua_call.

5.1 - Basic Functions

The basic library provides some core functions to Lua. If you do not include this library in your application, you should check carefully whether you need to provide implementations for some of its facilities.

assert (v [, message])

Issues an error when the value of its argument v is false (i.e., nil or false); otherwise, returns all its arguments. message is an error message; when absent, it defaults to "assertion failed!"

collectgarbage ([opt [, arg]])

This function is a generic interface to the garbage collector. It performs different functions according to its first argument, opt:

  • "collect": performs a full garbage-collection cycle. This is the default option.
  • "stop": stops the garbage collector.
  • "restart": restarts the garbage collector.
  • "count": returns the total memory in use by Lua (in Kbytes).
  • "step": performs a garbage-collection step. The step "size" is controlled by arg (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of arg. Returns true if the step finished a collection cycle.
  • "setpause": sets arg as the new value for the pause of the collector (see §2.10). Returns the previous value for pause.
  • "setstepmul": sets arg as the new value for the step multiplier of the collector (see §2.10). Returns the previous value for step.

dofile ([filename])

Opens the named file and executes its contents as a Lua chunk. When called without arguments, dofile executes the contents of the standard input (stdin). Returns all values returned by the chunk. In case of errors, dofile propagates the error to its caller (that is, dofile does not run in protected mode).

error (message [, level])

Terminates the last protected function called and returns message as the error message. Function error never returns.

Usually, error adds some information about the error position at the beginning of the message. The level argument specifies how to get the error position. With level 1 (the default), the error position is where the error function was called. Level 2 points the error to where the function that called error was called; and so on. Passing a level 0 avoids the addition of error position information to the message.

_G

A global variable (not a function) that holds the global environment (that is, _G._G = _G). Lua itself does not use this variable; changing its value does not affect any environment, nor vice-versa. (Use setfenv to change environments.)

getfenv ([f])

Returns the current environment in use by the function. f can be a Lua function or a number that specifies the function at that stack level: Level 1 is the function calling getfenv. If the given function is not a Lua function, or if f is 0, getfenv returns the global environment. The default for f is 1.

getmetatable (object)

If object does not have a metatable, returns nil. Otherwise, if the object's metatable has a "__metatable" field, returns the associated value. Otherwise, returns the metatable of the given object.

ipairs (t)

Returns three values: an iterator function, the table t, and 0, so that the construction 

     for i,v in ipairs(t) do body end

will iterate over the pairs (1,t[1]), (2,t[2]), ···, up to the first integer key absent from the table.

load (func [, chunkname])

Loads a chunk using function func to get its pieces. Each call to func must return a string that concatenates with previous results. A return of an empty string, nil, or no value signals the end of the chunk.

If there are no errors, returns the compiled chunk as a function; otherwise, returns nil plus the error message. The environment of the returned function is the global environment.

chunkname is used as the chunk name for error messages and debug information. When absent, it defaults to "=(load)".

loadfile ([filename])

Similar to load, but gets the chunk from file filename or from the standard input, if no file name is given.

loadstring (string [, chunkname])

Similar to load, but gets the chunk from the given string.

To load and run a given string, use the idiom 

     assert(loadstring(s))()

When absent, chunkname defaults to the given string.

next (table [, index])

Allows a program to traverse all fields of a table. Its first argument is a table and its second argument is an index in this table. next returns the next index of the table and its associated value. When called with nil as its second argument, next returns an initial index and its associated value. When called with the last index, or with nil in an empty table, next returns nil. If the second argument is absent, then it is interpreted as nil. In particular, you can use next(t) to check whether a table is empty.

The order in which the indices are enumerated is not specified, even for numeric indices. (To traverse a table in numeric order, use a numerical for or the ipairs function.)

The behavior of next is undefined if, during the traversal, you assign any value to a non-existent field in the table. You may however modify existing fields. In particular, you may clear existing fields.

pairs (t)

Returns three values: the next function, the table t, and nil, so that the construction 

     for k,v in pairs(t) do body end

will iterate over all key–value pairs of table t.

See function next for the caveats of modifying the table during its traversal.

pcall (f, arg1, ···)

Calls function f with the given arguments in protected mode. This means that any error inside f is not propagated; instead, pcall catches the error and returns a status code. Its first result is the status code (a boolean), which is true if the call succeeds without errors. In such case, pcall also returns all results from the call, after this first result. In case of any error, pcall returns false plus the error message.

print (···)

Receives any number of arguments, and prints their values to stdout, using the tostring function to convert them to strings. print is not intended for formatted output, but only as a quick way to show a value, typically for debugging. For formatted output, use string.format.

rawequal (v1, v2)

Checks whether v1 is equal to v2, without invoking any metamethod. Returns a boolean.

rawget (table, index)

Gets the real value of table[index], without invoking any metamethod. table must be a table; index may be any value.

rawset (table, index, value)

Sets the real value of table[index] to value, without invoking any metamethod. table must be a table, index any value different from nil, and value any Lua value.

This function returns table.

select (index, ···)

If index is a number, returns all arguments after argument number index. Otherwise, index must be the string "#", and select returns the total number of extra arguments it received.

setfenv (f, table)

Sets the environment to be used by the given function. f can be a Lua function or a number that specifies the function at that stack level: Level 1 is the function calling setfenv. setfenv returns the given function.

As a special case, when f is 0 setfenv changes the environment of the running thread. In this case, setfenv returns no values.

setmetatable (table, metatable)

Sets the metatable for the given table. (You cannot change the metatable of other types from Lua, only from C.) If metatable is nil, removes the metatable of the given table. If the original metatable has a "__metatable" field, raises an error.

This function returns table.

tonumber (e [, base])

Tries to convert its argument to a number. If the argument is already a number or a string convertible to a number, then tonumber returns this number; otherwise, it returns nil.

An optional argument specifies the base to interpret the numeral. The base may be any integer between 2 and 36, inclusive. In bases above 10, the letter 'A' (in either upper or lower case) represents 10, 'B' represents 11, and so forth, with 'Z' representing 35. In base 10 (the default), the number can have a decimal part, as well as an optional exponent part (see §2.1). In other bases, only unsigned integers are accepted.

tostring (e)

Receives an argument of any type and converts it to a string in a reasonable format. For complete control of how numbers are converted, use string.format.

If the metatable of e has a "__tostring" field, then tostring calls the corresponding value with e as argument, and uses the result of the call as its result.

type (v)

Returns the type of its only argument, coded as a string. The possible results of this function are "nil" (a string, not the value nil), "number", "string", "boolean", "table", "function", "thread", and "userdata".

unpack (list [, i [, j]])

Returns the elements from the given table. This function is equivalent to 
     return list[i], list[i+1], ···, list[j]

except that the above code can be written only for a fixed number of elements. By default, i is 1 and j is the length of the list, as defined by the length operator (see §2.5.5).

_VERSION

A global variable (not a function) that holds a string containing the current interpreter version. The current contents of this variable is "Lua 5.1".

xpcall (f, err)

This function is similar to pcall, except that you can set a new error handler.

xpcall calls function f in protected mode, using err as the error handler. Any error inside f is not propagated; instead, xpcall catches the error, calls the err function with the original error object, and returns a status code. Its first result is the status code (a boolean), which is true if the call succeeds without errors. In this case, xpcall also returns all results from the call, after this first result. In case of any error, xpcall returns false plus the result from err.

5.2 - Coroutine Manipulation

The operations related to coroutines comprise a sub-library of the basic library and come inside the table coroutine. See §2.11 for a general description of coroutines.

coroutine.create (f)

Creates a new coroutine, with body f. f must be a Lua function. Returns this new coroutine, an object with type "thread".

coroutine.resume (co [, val1, ···])

Starts or continues the execution of coroutine co. The first time you resume a coroutine, it starts running its body. The values val1, ··· are passed as the arguments to the body function. If the coroutine has yielded, resume restarts it; the values val1, ··· are passed as the results from the yield.

If the coroutine runs without any errors, resume returns true plus any values passed to yield (if the coroutine yields) or any values returned by the body function (if the coroutine terminates). If there is any error, resume returns false plus the error message.

coroutine.running ()

Returns the running coroutine, or nil when called by the main thread.

coroutine.status (co)

Returns the status of coroutine co, as a string: "running", if the coroutine is running (that is, it called status); "suspended", if the coroutine is suspended in a call to yield, or if it has not started running yet; "normal" if the coroutine is active but not running (that is, it has resumed another coroutine); and "dead" if the coroutine has finished its body function, or if it has stopped with an error.

coroutine.wrap (f)

Creates a new coroutine, with body f. f must be a Lua function. Returns a function that resumes the coroutine each time it is called. Any arguments passed to the function behave as the extra arguments to resume. Returns the same values returned by resume, except the first boolean. In case of error, propagates the error.

coroutine.yield (···)

Suspends the execution of the calling coroutine. The coroutine cannot be running a C function, a metamethod, or an iterator. Any arguments to yield are passed as extra results to resume.

5.3 - Modules

The package library provides basic facilities for loading and building modules in Lua. It exports two of its functions directly in the global environment: require and module. Everything else is exported in a table package.

module (name [, ···])

Creates a module. If there is a table in package.loaded[name], this table is the module. Otherwise, if there is a global table t with the given name, this table is the module. Otherwise creates a new table t and sets it as the value of the global name and the value of package.loaded[name]. This function also initializes t._NAME with the given name, t._M with the module (t itself), and t._PACKAGE with the package name (the full module name minus last component; see below). Finally, module sets t as the new environment of the current function and the new value of package.loaded[name], so that require returns t.

If name is a compound name (that is, one with components separated by dots), module creates (or reuses, if they already exist) tables for each component. For instance, if name is a.b.c, then module stores the module table in field c of field b of global a.

This function can receive optional options after the module name, where each option is a function to be applied over the module.

require (modname)

Loads the given module. The function starts by looking into the package.loaded table to determine whether modname is already loaded. If it is, then require returns the value stored at package.loaded[modname]. Otherwise, it tries to find a loader for the module.

To find a loader, require is guided by the package.loaders array. By changing this array, we can change how require looks for a module. The following explanation is based on the default configuration for package.loaders.

First require queries package.preload[modname]. If it has a value, this value (which should be a function) is the loader. Otherwise require searches for a Lua loader using the path stored in package.path. If that also fails, it searches for a C loader using the path stored in package.cpath. If that also fails, it tries an all-in-one loader (see package.loaders).

Once a loader is found, require calls the loader with a single argument, modname. If the loader returns any value, require assigns the returned value to package.loaded[modname]. If the loader returns no value and has not assigned any value to package.loaded[modname], then require assigns true to this entry. In any case, require returns the final value of package.loaded[modname].

If there is any error loading or running the module, or if it cannot find any loader for the module, then require signals an error.

package.cpath

The path used by require to search for a C loader.

Lua initializes the C path package.cpath in the same way it initializes the Lua path package.path, using the environment variable LUA_CPATH or a default path defined in luaconf.h.

package.loaded

A table used by require to control which modules are already loaded. When you require a module modname and package.loaded[modname] is not false, require simply returns the value stored there.

package.loaders

A table used by require to control how to load modules.

Each entry in this table is a searcher function. When looking for a module, require calls each of these searchers in ascending order, with the module name (the argument given to require) as its sole parameter. The function can return another function (the module loader) or a string explaining why it did not find that module (or nil if it has nothing to say). Lua initializes this table with four functions.

The first searcher simply looks for a loader in the package.preload table.

The second searcher looks for a loader as a Lua library, using the path stored at package.path. A path is a sequence of templates separated by semicolons. For each template, the searcher will change each interrogation mark in the template by filename, which is the module name with each dot replaced by a "directory separator" (such as "/" in Unix); then it will try to open the resulting file name. So, for instance, if the Lua path is the string 

     "./?.lua;./?.lc;/usr/local/?/init.lua"

the search for a Lua file for module foo will try to open the files ./foo.lua, ./foo.lc, and /usr/local/foo/init.lua, in that order.

The third searcher looks for a loader as a C library, using the path given by the variable package.cpath. For instance, if the C path is the string 

     "./?.so;./?.dll;/usr/local/?/init.so"

the searcher for module foo will try to open the files ./foo.so, ./foo.dll, and /usr/local/foo/init.so, in that order. Once it finds a C library, this searcher first uses a dynamic link facility to link the application with the library. Then it tries to find a C function inside the library to be used as the loader. The name of this C function is the string "luaopen_" concatenated with a copy of the module name where each dot is replaced by an underscore. Moreover, if the module name has a hyphen, its prefix up to (and including) the first hyphen is removed. For instance, if the module name is a.v1-b.c, the function name will be luaopen_b_c.

The fourth searcher tries an all-in-one loader. It searches the C path for a library for the root name of the given module. For instance, when requiring a.b.c, it will search for a C library for a. If found, it looks into it for an open function for the submodule; in our example, that would be luaopen_a_b_c. With this facility, a package can pack several C submodules into one single library, with each submodule keeping its original open function.

package.loadlib (libname, funcname)

Dynamically links the host program with the C library libname. Inside this library, looks for a function funcname and returns this function as a C function. (So, funcname must follow the protocol (see lua_CFunction)).

This is a low-level function. It completely bypasses the package and module system. Unlike require, it does not perform any path searching and does not automatically adds extensions. libname must be the complete file name of the C library, including if necessary a path and extension. funcname must be the exact name exported by the C library (which may depend on the C compiler and linker used).

This function is not supported by ANSI C. As such, it is only available on some platforms (Windows, Linux, Mac OS X, Solaris, BSD, plus other Unix systems that support the dlfcn standard).

package.path

The path used by require to search for a Lua loader.

At start-up, Lua initializes this variable with the value of the environment variable LUA_PATH or with a default path defined in luaconf.h, if the environment variable is not defined. Any ";;" in the value of the environment variable is replaced by the default path.

package.preload

A table to store loaders for specific modules (see require).

package.seeall (module)

Sets a metatable for module with its __index field referring to the global environment, so that this module inherits values from the global environment. To be used as an option to function module.

5.4 - String Manipulation

This library provides generic functions for string manipulation, such as finding and extracting substrings, and pattern matching. When indexing a string in Lua, the first character is at position 1 (not at 0, as in C). Indices are allowed to be negative and are interpreted as indexing backwards, from the end of the string. Thus, the last character is at position -1, and so on.

The string library provides all its functions inside the table string. It also sets a metatable for strings where the __index field points to the string table. Therefore, you can use the string functions in object-oriented style. For instance, string.byte(s, i) can be written as s:byte(i).

The string library assumes one-byte character encodings.

string.byte (s [, i [, j]])

Returns the internal numerical codes of the characters s[i], s[i+1], ···, s[j]. The default value for i is 1; the default value for j is i.

Note that numerical codes are not necessarily portable across platforms.

string.char (···)

Receives zero or more integers. Returns a string with length equal to the number of arguments, in which each character has the internal numerical code equal to its corresponding argument.

Note that numerical codes are not necessarily portable across platforms.

string.dump (function)

Returns a string containing a binary representation of the given function, so that a later loadstring on this string returns a copy of the function. function must be a Lua function without upvalues.

string.find (s, pattern [, init [, plain]])

Looks for the first match of pattern in the string s. If it finds a match, then find returns the indices of s where this occurrence starts and ends; otherwise, it returns nil. A third, optional numerical argument init specifies where to start the search; its default value is 1 and can be negative. A value of true as a fourth, optional argument plain turns off the pattern matching facilities, so the function does a plain "find substring" operation, with no characters in pattern being considered "magic". Note that if plain is given, then init must be given as well.

If the pattern has captures, then in a successful match the captured values are also returned, after the two indices.

string.format (formatstring, ···)

Returns a formatted version of its variable number of arguments following the description given in its first argument (which must be a string). The format string follows the same rules as the printf family of standard C functions. The only differences are that the options/modifiers *, l, L, n, p, and h are not supported and that there is an extra option, q. The q option formats a string in a form suitable to be safely read back by the Lua interpreter: the string is written between double quotes, and all double quotes, newlines, embedded zeros, and backslashes in the string are correctly escaped when written. For instance, the call 
     string.format('%q', 'a string with "quotes" and \n new line')

will produce the string: 

     "a string with \"quotes\" and \
      new line"

The options c, d, E, e, f, g, G, i, o, u, X, and x all expect a number as argument, whereas q and s expect a string.

This function does not accept string values containing embedded zeros, except as arguments to the q option.

string.gmatch (s, pattern)

Returns an iterator function that, each time it is called, returns the next captures from pattern over string s. If pattern specifies no captures, then the whole match is produced in each call.

As an example, the following loop 

     s = "hello world from Lua"
     for w in string.gmatch(s, "%a+") do
       print(w)
     end

will iterate over all the words from string s, printing one per line. The next example collects all pairs key=value from the given string into a table: 

     t = {}
     s = "from=world, to=Lua"
     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
       t[k] = v
     end

For this function, a '^' at the start of a pattern does not work as an anchor, as this would prevent the iteration.

string.gsub (s, pattern, repl [, n])

Returns a copy of s in which all (or the first n, if given) occurrences of the pattern have been replaced by a replacement string specified by repl, which can be a string, a table, or a function. gsub also returns, as its second value, the total number of matches that occurred.

If repl is a string, then its value is used for replacement. The character % works as an escape character: any sequence in repl of the form %n, with n between 1 and 9, stands for the value of the n-th captured substring (see below). The sequence %0 stands for the whole match. The sequence %% stands for a single %.

If repl is a table, then the table is queried for every match, using the first capture as the key; if the pattern specifies no captures, then the whole match is used as the key.

If repl is a function, then this function is called every time a match occurs, with all captured substrings passed as arguments, in order; if the pattern specifies no captures, then the whole match is passed as a sole argument.

If the value returned by the table query or by the function call is a string or a number, then it is used as the replacement string; otherwise, if it is false or nil, then there is no replacement (that is, the original match is kept in the string).

Here are some examples: 

     x = string.gsub("hello world", "(%w+)", "%1 %1")
     --> x="hello hello world world"
     
     x = string.gsub("hello world", "%w+", "%0 %0", 1)
     --> x="hello hello world"
     
     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
     --> x="world hello Lua from"
     
     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
     --> x="home = /home/roberto, user = roberto"
     
     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
           return loadstring(s)()
         end)
     --> x="4+5 = 9"
     
     local t = {name="lua", version="5.1"}
     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
     --> x="lua-5.1.tar.gz"

string.len (s)

Receives a string and returns its length. The empty string "" has length 0. Embedded zeros are counted, so "a\000bc\000" has length 5.

string.lower (s)

Receives a string and returns a copy of this string with all uppercase letters changed to lowercase. All other characters are left unchanged. The definition of what an uppercase letter is depends on the current locale.

string.match (s, pattern [, init])

Looks for the first match of pattern in the string s. If it finds one, then match returns the captures from the pattern; otherwise it returns nil. If pattern specifies no captures, then the whole match is returned. A third, optional numerical argument init specifies where to start the search; its default value is 1 and can be negative.

string.rep (s, n)

Returns a string that is the concatenation of n copies of the string s.

string.reverse (s)

Returns a string that is the string s reversed.

string.sub (s, i [, j])

Returns the substring of s that starts at i and continues until j; i and j can be negative. If j is absent, then it is assumed to be equal to -1 (which is the same as the string length). In particular, the call string.sub(s,1,j) returns a prefix of s with length j, and string.sub(s, -i) returns a suffix of s with length i.

string.upper (s)

Receives a string and returns a copy of this string with all lowercase letters changed to uppercase. All other characters are left unchanged. The definition of what a lowercase letter is depends on the current locale.

5.4.1 - Patterns

Character Class:

A character class is used to represent a set of characters. The following combinations are allowed in describing a character class:

  • x: (where x is not one of the magic characters ^$()%.[]*+-?) represents the character x itself.
  • .: (a dot) represents all characters.
  • %a: represents all letters.
  • %c: represents all control characters.
  • %d: represents all digits.
  • %l: represents all lowercase letters.
  • %p: represents all punctuation characters.
  • %s: represents all space characters.
  • %u: represents all uppercase letters.
  • %w: represents all alphanumeric characters.
  • %x: represents all hexadecimal digits.
  • %z: represents the character with representation 0.
  • %x: (where x is any non-alphanumeric character) represents the character x. This is the standard way to escape the magic characters. Any punctuation character (even the non magic) can be preceded by a '%' when used to represent itself in a pattern.
  • [set]: represents the class which is the union of all characters in set. A range of characters can be specified by separating the end characters of the range with a '-'. All classes %x described above can also be used as components in set. All other characters in set represent themselves. For example, [%w_] (or [_%w]) represents all alphanumeric characters plus the underscore, [0-7] represents the octal digits, and [0-7%l%-] represents the octal digits plus the lowercase letters plus the '-' character.

    The interaction between ranges and classes is not defined. Therefore, patterns like [%a-z] or [a-%%] have no meaning.

  • [^set]: represents the complement of set, where set is interpreted as above.

For all classes represented by single letters (%a, %c, etc.), the corresponding uppercase letter represents the complement of the class. For instance, %S represents all non-space characters.

The definitions of letter, space, and other character groups depend on the current locale. In particular, the class [a-z] may not be equivalent to %l.

Pattern Item:

A pattern item can be

  • a single character class, which matches any single character in the class;
  • a single character class followed by '*', which matches 0 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence;
  • a single character class followed by '+', which matches 1 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence;
  • a single character class followed by '-', which also matches 0 or more repetitions of characters in the class. Unlike '*', these repetition items will always match the shortest possible sequence;
  • a single character class followed by '?', which matches 0 or 1 occurrence of a character in the class;
  • %n, for n between 1 and 9; such item matches a substring equal to the n-th captured string (see below);
  • %bxy, where x and y are two distinct characters; such item matches strings that start with x, end with y, and where the x and y are balanced. This means that, if one reads the string from left to right, counting +1 for an x and -1 for a y, the ending y is the first y where the count reaches 0. For instance, the item %b() matches expressions with balanced parentheses.

Pattern:

A pattern is a sequence of pattern items. A '^' at the beginning of a pattern anchors the match at the beginning of the subject string. A '$' at the end of a pattern anchors the match at the end of the subject string. At other positions, '^' and '$' have no special meaning and represent themselves.

Captures:

A pattern can contain sub-patterns enclosed in parentheses; they describe captures. When a match succeeds, the substrings of the subject string that match captures are stored (captured) for future use. Captures are numbered according to their left parentheses. For instance, in the pattern "(a*(.)%w(%s*))", the part of the string matching "a*(.)%w(%s*)" is stored as the first capture (and therefore has number 1); the character matching "." is captured with number 2, and the part matching "%s*" has number 3.

As a special case, the empty capture () captures the current string position (a number). For instance, if we apply the pattern "()aa()" on the string "flaaap", there will be two captures: 3 and 5.

A pattern cannot contain embedded zeros. Use %z instead.

5.5 - Table Manipulation

This library provides generic functions for table manipulation. It provides all its functions inside the table table.

Most functions in the table library assume that the table represents an array or a list. For these functions, when we talk about the "length" of a table we mean the result of the length operator.

table.concat (table [, sep [, i [, j]]])

Given an array where all elements are strings or numbers, returns table[i]..sep..table[i+1] ··· sep..table[j]. The default value for sep is the empty string, the default for i is 1, and the default for j is the length of the table. If i is greater than j, returns the empty string.

table.insert (table, [pos,] value)

Inserts element value at position pos in table, shifting up other elements to open space, if necessary. The default value for pos is n+1, where n is the length of the table (see §2.5.5), so that a call table.insert(t,x) inserts x at the end of table t.

table.maxn (table)

Returns the largest positive numerical index of the given table, or zero if the table has no positive numerical indices. (To do its job this function does a linear traversal of the whole table.)

table.remove (table [, pos])

Removes from table the element at position pos, shifting down other elements to close the space, if necessary. Returns the value of the removed element. The default value for pos is n, where n is the length of the table, so that a call table.remove(t) removes the last element of table t.

table.sort (table [, comp])

Sorts table elements in a given order, in-place, from table[1] to table[n], where n is the length of the table. If comp is given, then it must be a function that receives two table elements, and returns true when the first is less than the second (so that not comp(a[i+1],a[i]) will be true after the sort). If comp is not given, then the standard Lua operator < is used instead.

The sort algorithm is not stable; that is, elements considered equal by the given order may have their relative positions changed by the sort.

5.6 - Mathematical Functions

This library is an interface to the standard C math library. It provides all its functions inside the table math.

math.abs (x)

Returns the absolute value of x.

math.acos (x)

Returns the arc cosine of x (in radians).

math.asin (x)

Returns the arc sine of x (in radians).

math.atan (x)

Returns the arc tangent of x (in radians).

math.atan2 (y, x)

Returns the arc tangent of y/x (in radians), but uses the signs of both parameters to find the quadrant of the result. (It also handles correctly the case of x being zero.)

math.ceil (x)

Returns the smallest integer larger than or equal to x.

math.cos (x)

Returns the cosine of x (assumed to be in radians).

math.cosh (x)

Returns the hyperbolic cosine of x.

math.floor (x)

Returns the largest integer smaller than or equal to x.

math.fmod (x, y)

Returns the remainder of the division of x by y that rounds the quotient towards zero.

math.frexp (x)

Returns m and e such that x = m2e, e is an integer and the absolute value of m is in the range [0.5, 1) (or zero when x is zero).

math.huge

The value HUGE_VAL, a value larger than or equal to any other numerical value.

math.ldexp (m, e)

Returns the minimum value among its arguments.

math.modf (x)

Returns two numbers, the integral part of x and the fractional part of x.

math.pi

The value of pi.

math.pow (x, y)

Returns xy. (You can also use the expression x^y to compute this value.)

math.rad (x)

Returns the angle x (given in degrees) in radians.

math.random ([m [, n]])

This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. (No guarantees can be given for its statistical properties.)

When called without arguments, returns a uniform pseudo-random real number in the range [0,1). When called with an integer number m, math.random returns a uniform pseudo-random integer in the range [1, m]. When called with two integer numbers m and n, math.random returns a uniform pseudo-random integer in the range [m, n].

math.randomseed (x)

Sets x as the "seed" for the pseudo-random generator: equal seeds produce equal sequences of numbers.

math.sin (x)

Returns the sine of x (assumed to be in radians).

math.sinh (x)

Returns the hyperbolic sine of x.

math.sqrt (x)

Returns the square root of x. (You can also use the expression x^0.5 to compute this value.)

math.tan (x)

Returns the tangent of x (assumed to be in radians).

math.tanh (x)

Returns the hyperbolic tangent of x.

5.7 - Input and Output Facilities

The I/O library provides two different styles for file manipulation. The first one uses implicit file descriptors; that is, there are operations to set a default input file and a default output file, and all input/output operations are over these default files. The second style uses explicit file descriptors.

When using implicit file descriptors, all operations are supplied by table io. When using explicit file descriptors, the operation io.open returns a file descriptor and then all operations are supplied as methods of the file descriptor.

The table io also provides three predefined file descriptors with their usual meanings from C: io.stdin, io.stdout, and io.stderr. The I/O library never closes these files.

Unless otherwise stated, all I/O functions return nil on failure (plus an error message as a second result and a system-dependent error code as a third result) and some value different from nil on success.

io.close ([file])

Equivalent to file:close(). Without a file, closes the default output file.

io.flush ()

Equivalent to file:flush over the default output file.

io.input ([file])

When called with a file name, it opens the named file (in text mode), and sets its handle as the default input file. When called with a file handle, it simply sets this file handle as the default input file. When called without parameters, it returns the current default input file.

In case of errors this function raises the error, instead of returning an error code.

io.lines ([filename])

Opens the given file name in read mode and returns an iterator function that, each time it is called, returns a new line from the file. Therefore, the construction 

     for line in io.lines(filename) do body end

will iterate over all lines of the file. When the iterator function detects the end of file, it returns nil (to finish the loop) and automatically closes the file.

The call io.lines() (with no file name) is equivalent to io.input():lines(); that is, it iterates over the lines of the default input file. In this case it does not close the file when the loop ends.

io.open (filename [, mode])

This function opens a file, in the mode specified in the string mode. It returns a new file handle, or, in case of errors, nil plus an error message.

The mode string can be any of the following:

  • "r": read mode (the default);
  • "w": write mode;
  • "a": append mode;
  • "r+": update mode, all previous data is preserved;
  • "w+": update mode, all previous data is erased;
  • "a+": append update mode, previous data is preserved, writing is only allowed at the end of file.

The mode string can also have a 'b' at the end, which is needed in some systems to open the file in binary mode. This string is exactly what is used in the standard C function fopen.

io.output ([file])

Similar to io.input, but operates over the default output file.

io.popen (prog [, mode])

Starts program prog in a separated process and returns a file handle that you can use to read data from this program (if mode is "r", the default) or to write data to this program (if mode is "w").

This function is system dependent and is not available on all platforms.

io.read (···)

Equivalent to io.input():read.

io.tmpfile ()

Returns a handle for a temporary file. This file is opened in update mode and it is automatically removed when the program ends.

io.type (obj)

Checks whether obj is a valid file handle. Returns the string "file" if obj is an open file handle, "closed file" if obj is a closed file handle, or nil if obj is not a file handle.

io.write (···)

Equivalent to io.output():write.

file:close ()

Closes file. Note that files are automatically closed when their handles are garbage collected, but that takes an unpredictable amount of time to happen.

file:flush ()

Saves any written data to file.

file:lines ()

Returns an iterator function that, each time it is called, returns a new line from the file. Therefore, the construction 

     for line in file:lines() do body end

will iterate over all lines of the file. (Unlike io.lines, this function does not close the file when the loop ends.)

file:read (···)

Reads the file file, according to the given formats, which specify what to read. For each format, the function returns a string (or a number) with the characters read, or nil if it cannot read data with the specified format. When called without formats, it uses a default format that reads the entire next line (see below).

The available formats are

  • "*n": reads a number; this is the only format that returns a number instead of a string.
  • "*a": reads the whole file, starting at the current position. On end of file, it returns the empty string.
  • "*l": reads the next line (skipping the end of line), returning nil on end of file. This is the default format.
  • number: reads a string with up to this number of characters, returning nil on end of file. If number is zero, it reads nothing and returns an empty string, or nil on end of file.

file:seek ([whence] [, offset])

Sets and gets the file position, measured from the beginning of the file, to the position given by offset plus a base specified by the string whence, as follows:

  • "set": base is position 0 (beginning of the file);
  • "cur": base is current position;
  • "end": base is end of file;

In case of success, function seek returns the final file position, measured in bytes from the beginning of the file. If this function fails, it returns nil, plus a string describing the error.

The default value for whence is "cur", and for offset is 0. Therefore, the call file:seek() returns the current file position, without changing it; the call file:seek("set") sets the position to the beginning of the file (and returns 0); and the call file:seek("end") sets the position to the end of the file, and returns its size.

file:setvbuf (mode [, size])

Sets the buffering mode for an output file. There are three available modes:

  • "no": no buffering; the result of any output operation appears immediately.
  • "full": full buffering; output operation is performed only when the buffer is full (or when you explicitly flush the file (see io.flush)).
  • "line": line buffering; output is buffered until a newline is output or there is any input from some special files (such as a terminal device).

For the last two cases, size specifies the size of the buffer, in bytes. The default is an appropriate size.

file:write (···)

Writes the value of each of its arguments to the file. The arguments must be strings or numbers. To write other values, use tostring or string.format before write.

5.8 - Operating System Facilities

This library is implemented through table os.

os.clock ()

Returns an approximation of the amount in seconds of CPU time used by the program.

os.date ([format [, time]])

Returns a string or a table containing date and time, formatted according to the given string format.

If the time argument is present, this is the time to be formatted (see the os.time function for a description of this value). Otherwise, date formats the current time.

If format starts with '!', then the date is formatted in Coordinated Universal Time. After this optional character, if format is the string "*t", then date returns a table with the following fields: year (four digits), month (1--12), day (1--31), hour (0--23), min (0--59), sec (0--61), wday (weekday, Sunday is 1), yday (day of the year), and isdst (daylight saving flag, a boolean).

If format is not "*t", then date returns the date as a string, formatted according to the same rules as the C function strftime.

When called without arguments, date returns a reasonable date and time representation that depends on the host system and on the current locale (that is, os.date() is equivalent to os.date("%c")).

os.difftime (t2, t1)

Returns the number of seconds from time t1 to time t2. In POSIX, Windows, and some other systems, this value is exactly t2-t1.

os.execute ([command])

This function is equivalent to the C function system. It passes command to be executed by an operating system shell. It returns a status code, which is system-dependent. If command is absent, then it returns nonzero if a shell is available and zero otherwise.

os.exit ([code])

Calls the C function exit, with an optional code, to terminate the host program. The default value for code is the success code.

os.getenv (varname)

Returns the value of the process environment variable varname, or nil if the variable is not defined.

os.remove (filename)

Deletes the file or directory with the given name. Directories must be empty to be removed. If this function fails, it returns nil, plus a string describing the error.

os.rename (oldname, newname)

Renames file or directory named oldname to newname. If this function fails, it returns nil, plus a string describing the error.

os.setlocale (locale [, category])

Sets the current locale of the program. locale is a string specifying a locale; category is an optional string describing which category to change: "all", "collate", "ctype", "monetary", "numeric", or "time"; the default category is "all". The function returns the name of the new locale, or nil if the request cannot be honored.

If locale is the empty string, the current locale is set to an implementation-defined native locale. If locale is the string "C", the current locale is set to the standard C locale.

When called with nil as the first argument, this function only returns the name of the current locale for the given category.

os.time ([table])

Returns the current time when called without arguments, or a time representing the date and time specified by the given table. This table must have fields year, month, and day, and may have fields hour, min, sec, and isdst (for a description of these fields, see the os.date function).

The returned value is a number, whose meaning depends on your system. In POSIX, Windows, and some other systems, this number counts the number of seconds since some given start time (the "epoch"). In other systems, the meaning is not specified, and the number returned by time can be used only as an argument to date and difftime.

os.tmpname ()

Returns a string with a file name that can be used for a temporary file. The file must be explicitly opened before its use and explicitly removed when no longer needed.

On some systems (POSIX), this function also creates a file with that name, to avoid security risks. (Someone else might create the file with wrong permissions in the time between getting the name and creating the file.) You still have to open the file to use it and to remove it (even if you do not use it).

When possible, you may prefer to use io.tmpfile, which automatically removes the file when the program ends.

5.9 - The Debug Library

This library provides the functionality of the debug interface to Lua programs. You should exert care when using this library. The functions provided here should be used exclusively for debugging and similar tasks, such as profiling. Please resist the temptation to use them as a usual programming tool: they can be very slow. Moreover, several of these functions violate some assumptions about Lua code (e.g., that variables local to a function cannot be accessed from outside or that userdata metatables cannot be changed by Lua code) and therefore can compromise otherwise secure code.

All functions in this library are provided inside the debug table. All functions that operate over a thread have an optional first argument which is the thread to operate over. The default is always the current thread.

debug.debug ()

Enters an interactive mode with the user, running each string that the user enters. Using simple commands and other debug facilities, the user can inspect global and local variables, change their values, evaluate expressions, and so on. A line containing only the word cont finishes this function, so that the caller continues its execution.

Note that commands for debug.debug are not lexically nested within any function, and so have no direct access to local variables.

debug.getfenv (o)

Returns the environment of object o.

debug.gethook ([thread])

Returns the current hook settings of the thread, as three values: the current hook function, the current hook mask, and the current hook count (as set by the debug.sethook function).

debug.getinfo ([thread,] function [, what])

Returns a table with information about a function. You can give the function directly, or you can give a number as the value of function, which means the function running at level function of the call stack of the given thread: level 0 is the current function (getinfo itself); level 1 is the function that called getinfo; and so on. If function is a number larger than the number of active functions, then getinfo returns nil.

The returned table can contain all the fields returned by lua_getinfo, with the string what describing which fields to fill in. The default for what is to get all information available, except the table of valid lines. If present, the option 'f' adds a field named func with the function itself. If present, the option 'L' adds a field named activelines with the table of valid lines.

For instance, the expression debug.getinfo(1,"n").name returns a table with a name for the current function, if a reasonable name can be found, and the expression debug.getinfo(print) returns a table with all available information about the print function.

debug.getlocal ([thread,] level, local)

This function returns the name and the value of the local variable with index local of the function at level level of the stack. (The first parameter or local variable has index 1, and so on, until the last active local variable.) The function returns nil if there is no local variable with the given index, and raises an error when called with a level out of range. (You can call debug.getinfo to check whether the level is valid.)

Variable names starting with '(' (open parentheses) represent internal variables (loop control variables, temporaries, and C function locals).

debug.getmetatable (object)

Returns the metatable of the given object or nil if it does not have a metatable.

debug.getregistry ()

Returns the registry table (see §3.5).

debug.getupvalue (func, up)

This function returns the name and the value of the upvalue with index up of the function func. The function returns nil if there is no upvalue with the given index.

debug.setfenv (object, table)

Sets the environment of the given object to the given table. Returns object.

debug.sethook ([thread,] hook, mask [, count])

Sets the given function as a hook. The string mask and the number count describe when the hook will be called. The string mask may have the following characters, with the given meaning:

  • "c": the hook is called every time Lua calls a function;
  • "r": the hook is called every time Lua returns from a function;
  • "l": the hook is called every time Lua enters a new line of code.

With a count different from zero, the hook is called after every count instructions.

When called without arguments, debug.sethook turns off the hook.

When the hook is called, its first parameter is a string describing the event that has triggered its call: "call", "return" (or "tail return", when simulating a return from a tail call), "line", and "count". For line events, the hook also gets the new line number as its second parameter. Inside a hook, you can call getinfo with level 2 to get more information about the running function (level 0 is the getinfo function, and level 1 is the hook function), unless the event is "tail return". In this case, Lua is only simulating the return, and a call to getinfo will return invalid data.

debug.setlocal ([thread,] level, local, value)

This function assigns the value value to the local variable with index local of the function at level level of the stack. The function returns nil if there is no local variable with the given index, and raises an error when called with a level out of range. (You can call getinfo to check whether the level is valid.) Otherwise, it returns the name of the local variable.

debug.setmetatable (object, table)

Sets the metatable for the given object to the given table (which can be nil).

debug.setupvalue (func, up, value)

This function assigns the value value to the upvalue with index up of the function func. The function returns nil if there is no upvalue with the given index. Otherwise, it returns the name of the upvalue.

debug.traceback ([thread,] [message [, level]])

Returns a string with a traceback of the call stack. An optional message string is appended at the beginning of the traceback. An optional level number tells at which level to start the traceback (default is 1, the function calling traceback).

6 - Lua Stand-alone

Although Lua has been designed as an extension language, to be embedded in a host C program, it is also frequently used as a stand-alone language. An interpreter for Lua as a stand-alone language, called simply lua, is provided with the standard distribution. The stand-alone interpreter includes all standard libraries, including the debug library. Its usage is: 

     lua [options] [script [args]]

The options are:

  • -e stat: executes string stat;
  • -l mod: "requires" mod;
  • -i: enters interactive mode after running script;
  • -v: prints version information;
  • --: stops handling options;
  • -: executes stdin as a file and stops handling options.

After handling its options, lua runs the given script, passing to it the given args as string arguments. When called without arguments, lua behaves as lua -v -i when the standard input (stdin) is a terminal, and as lua - otherwise.

Before running any argument, the interpreter checks for an environment variable LUA_INIT. If its format is @filename, then lua executes the file. Otherwise, lua executes the string itself.

All options are handled in order, except -i. For instance, an invocation like 

     $ lua -e'a=1' -e 'print(a)' script.lua

will first set a to 1, then print the value of a (which is '1'), and finally run the file script.lua with no arguments. (Here $ is the shell prompt. Your prompt may be different.)

Before starting to run the script, lua collects all arguments in the command line in a global table called arg. The script name is stored at index 0, the first argument after the script name goes to index 1, and so on. Any arguments before the script name (that is, the interpreter name plus the options) go to negative indices. For instance, in the call 

     $ lua -la b.lua t1 t2

the interpreter first runs the file a.lua, then creates a table 

     arg = { [-2] = "lua", [-1] = "-la",
             [0] = "b.lua",
             [1] = "t1", [2] = "t2" }

and finally runs the file b.lua. The script is called with arg[1], arg[2], ··· as arguments; it can also access these arguments with the vararg expression '...'.

In interactive mode, if you write an incomplete statement, the interpreter waits for its completion by issuing a different prompt.

If the global variable _PROMPT contains a string, then its value is used as the prompt. Similarly, if the global variable _PROMPT2 contains a string, its value is used as the secondary prompt (issued during incomplete statements). Therefore, both prompts can be changed directly on the command line or in any Lua programs by assigning to _PROMPT. See the next example: 

     $ lua -e"_PROMPT='myprompt> '" -i

(The outer pair of quotes is for the shell, the inner pair is for Lua.) Note the use of -i to enter interactive mode; otherwise, the program would just end silently right after the assignment to _PROMPT.

To allow the use of Lua as a script interpreter in Unix systems, the stand-alone interpreter skips the first line of a chunk if it starts with #. Therefore, Lua scripts can be made into executable programs by using chmod +x and the #! form, as in 

     #!/usr/local/bin/lua

(Of course, the location of the Lua interpreter may be different in your machine. If lua is in your PATH, then 

     #!/usr/bin/env lua

is a more portable solution.)

7 - Incompatibilities with the Previous Version

Here we list the incompatibilities that you may find when moving a program from Lua 5.0 to Lua 5.1. You can avoid most of the incompatibilities compiling Lua with appropriate options (see file luaconf.h). However, all these compatibility options will be removed in the next version of Lua.

7.1 - Changes in the Language

  • The vararg system changed from the pseudo-argument arg with a table with the extra arguments to the vararg expression. (See compile-time option LUA_COMPAT_VARARG in luaconf.h.)
  • There was a subtle change in the scope of the implicit variables of the for statement and for the repeat statement.
  • The long string/long comment syntax ([[string]]) does not allow nesting. You can use the new syntax ([=[string]=]) in these cases. (See compile-time option LUA_COMPAT_LSTR in luaconf.h.)

7.2 - Changes in the Libraries

  • Function string.gfind was renamed string.gmatch. (See compile-time option LUA_COMPAT_GFIND in luaconf.h.)
  • When string.gsub is called with a function as its third argument, whenever this function returns nil or false the replacement string is the whole match, instead of the empty string.
  • Function table.setn was deprecated. Function table.getn corresponds to the new length operator (#); use the operator instead of the function. (See compile-time option LUA_COMPAT_GETN in luaconf.h.)
  • Function loadlib was renamed package.loadlib. (See compile-time option LUA_COMPAT_LOADLIB in luaconf.h.)
  • Function math.mod was renamed math.fmod. (See compile-time option LUA_COMPAT_MOD in luaconf.h.)
  • Functions table.foreach and table.foreachi are deprecated. You can use a for loop with pairs or ipairs instead.
  • There were substantial changes in function require due to the new module system. However, the new behavior is mostly compatible with the old, but require gets the path from package.path instead of from LUA_PATH.
  • Function collectgarbage has different arguments. Function gcinfo is deprecated; use collectgarbage("count") instead.

7.3 - Changes in the API

  • The luaopen_* functions (to open libraries) cannot be called directly, like a regular C function. They must be called through Lua, like a Lua function.
  • Function lua_open was replaced by lua_newstate to allow the user to set a memory-allocation function. You can use luaL_newstate from the standard library to create a state with a standard allocation function (based on realloc).
  • Functions luaL_getn and luaL_setn (from the auxiliary library) are deprecated. Use lua_objlen instead of luaL_getn and nothing instead of luaL_setn.
  • Function luaL_openlib was replaced by luaL_register.
  • Function luaL_checkudata now throws an error when the given value is not a userdata of the expected type. (In Lua 5.0 it returned NULL.)

This is useful if you # have a standard template that goes to all Redis servers but also need # to customize a few per-server settings. Include files can include # other files, so use this wisely. # # Notice option "include" won't be rewritten by command "CONFIG REWRITE" # from admin or Redis Sentinel.

So by default we uncomment the # following bind directive, that will force Redis to listen only into # the IPv4 lookback interface address (this means Redis will be able to # accept connections only from clients running into the same computer it # is running). # # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES # JUST COMMENT THE FOLLOWING LINE. # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bind 127.0.0.1 # Protected mode is a layer of security protection, in order to avoid that # Redis instances left open on the internet are accessed and exploited. # # When protected mode is on and if: # # 1) The server is not binding explicitly to a set of addresses using the # "bind" directive. # 2) No password is configured. # # The server only accepts connections from clients connecting from the # IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain # sockets. # # By default protected mode is enabled. You should disable it only if # you are sure you want clients from other hosts to connect to Redis # even if no authentication is configured, nor a specific set of interfaces # are explicitly listed using the "bind" directive. protected-mode yes # Accept connections on the specified port, default is 6379 (IANA #815344). # If port 0 is specified Redis will not listen on a TCP socket. port 6379 # TCP listen() backlog. # # In high requests-per-second environments you need an high backlog in order # to avoid slow clients connections issues.

Use slaveof to make a Redis instance a copy of # another Redis server. A few things to understand ASAP about Redis replication. # # 1) Redis replication is asynchronous, but you can configure a master to # stop accepting writes if it appears to be not connected with at least # a given number of slaves. # 2) Redis slaves are able to perform a partial resynchronization with the # master if the replication link is lost for a relatively small amount of # time. You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. After a # network partition slaves automatically try to reconnect to masters # and resynchronize with them. # # slaveof # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the slave to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the slave request. # # masterauth # When a slave loses its connection with the master, or when the replication # is still in progress, the slave can act in two different ways: # # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will # still reply to client requests, possibly with out of date data, or the # data set may just be empty if this is the first synchronization. # # 2) if slave-serve-stale-data is set to 'no' the slave will reply with # an error "SYNC with master in progress" to all the kind of commands # but to INFO and SLAVEOF. # slave-serve-stale-data yes # You can configure a slave instance to accept writes or not. Writing against # a slave instance may be useful to store some ephemeral data (because data # written on a slave will be easily deleted after resync with the master) but # may also cause problems if clients are writing to it because of a # misconfiguration. # # Since Redis 2.6 by default slaves are read-only. # # Note: read only slaves are not designed to be exposed to untrusted clients # on the internet. It's just a protection layer against misuse of the instance. # Still a read only slave exports by default all the administrative commands # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve # security of read only slaves using 'rename-command' to shadow all the # administrative / dangerous commands. slave-read-only yes # Replication SYNC strategy: disk or socket. # # ------------------------------------------------------- # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY # ------------------------------------------------------- # # New slaves and reconnecting slaves that are not able to continue the replication # process just receiving differences, need to do what is called a "full # synchronization". An RDB file is transmitted from the master to the slaves. # The transmission can happen in two different ways: # # 1) Disk-backed: The Redis master creates a new process that writes the RDB # file on disk. Later the file is transferred by the parent # process to the slaves incrementally. # 2) Diskless: The Redis master creates a new process that directly writes the # RDB file to slave sockets, without touching the disk at all. # # With disk-backed replication, while the RDB file is generated, more slaves # can be queued and served with the RDB file as soon as the current child producing # the RDB file finishes its work. With diskless replication instead once # the transfer starts, new slaves arriving will be queued and a new transfer # will start when the current one terminates. # # When diskless replication is used, the master waits a configurable amount of # time (in seconds) before starting the transfer in the hope that multiple slaves # will arrive and the transfer can be parallelized. # # With slow disks and fast (large bandwidth) networks, diskless replication # works better. repl-diskless-sync no # When diskless replication is enabled, it is possible to configure the delay # the server waits in order to spawn the child that transfers the RDB via socket # to the slaves. # # This is important since once the transfer starts, it is not possible to serve # new slaves arriving, that will be queued for the next RDB transfer, so the server # waits a delay in order to let more slaves arrive. # # The delay is specified in seconds, and by default is 5 seconds. To disable # it entirely just set it to 0 seconds and the transfer will start ASAP. repl-diskless-sync-delay 5 # Slaves send PINGs to server in a predefined interval. It's possible to change # this interval with the repl_ping_slave_period option. The default value is 10 # seconds. # # repl-ping-slave-period 10 # The following option sets the replication timeout for: # # 1) Bulk transfer I/O during SYNC, from the point of view of slave. # 2) Master timeout from the point of view of slaves (data, pings). # 3) Slave timeout from the point of view of masters (REPLCONF ACK pings). # # It is important to make sure that this value is greater than the value # specified for repl-ping-slave-period otherwise a timeout will be detected # every time there is low traffic between the master and the slave. # # repl-timeout 60 # Disable TCP_NODELAY on the slave socket after SYNC? # # If you select "yes" Redis will use a smaller number of TCP packets and # less bandwidth to send data to slaves. But this can add a delay for # the data to appear on the slave side, up to 40 milliseconds with # Linux kernels using a default configuration. # # If you select "no" the delay for data to appear on the slave side will # be reduced but more bandwidth will be used for replication. # # By default we optimize for low latency, but in very high traffic conditions # or when the master and slaves are many hops away, turning this to "yes" may # be a good idea. repl-disable-tcp-nodelay no # Set the replication backlog size. The backlog is a buffer that accumulates # slave data when slaves are disconnected for some time, so that when a slave # wants to reconnect again, often a full resync is not needed, but a partial # resync is enough, just passing the portion of data the slave missed while # disconnected. # # The bigger the replication backlog, the longer the time the slave can be # disconnected and later be able to perform a partial resynchronization. # # The backlog is only allocated once there is at least a slave connected. # # repl-backlog-size 1mb # After a master has no longer connected slaves for some time, the backlog # will be freed. The following option configures the amount of seconds that # need to elapse, starting from the time the last slave disconnected, for # the backlog buffer to be freed. # # A value of 0 means to never release the backlog. # # repl-backlog-ttl 3600 # The slave priority is an integer number published by Redis in the INFO output. # It is used by Redis Sentinel in order to select a slave to promote into a # master if the master is no longer working correctly. # # A slave with a low priority number is considered better for promotion, so # for instance if there are three slaves with priority 10, 100, 25 Sentinel will # pick the one with priority 10, that is the lowest. # # However a special priority of 0 marks the slave as not able to perform the # role of master, so a slave with priority of 0 will never be selected by # Redis Sentinel for promotion. # # By default the priority is 100. slave-priority 100 # It is possible for a master to stop accepting writes if there are less than # N slaves connected, having a lag less or equal than M seconds. # # The N slaves need to be in "online" state. # # The lag in seconds, that must be <= the specified value, is calculated from # the last ping received from the slave, that is usually sent every second. # # This option does not GUARANTEE that N replicas will accept the write, but # will limit the window of exposure for lost writes in case not enough slaves # are available, to the specified number of seconds. # # For example to require at least 3 slaves with a lag <= 10 seconds use: # # min-slaves-to-write 3 # min-slaves-max-lag 10 # # Setting one or the other to 0 disables the feature. # # By default min-slaves-to-write is set to 0 (feature disabled) and # min-slaves-max-lag is set to 10. # A Redis master is able to list the address and port of the attached # slaves in different ways. For example the "INFO replication" section # offers this information, which is used, among other tools, by # Redis Sentinel in order to discover slave instances. # Another place where this info is available is in the output of the # "ROLE" command of a masteer. # # The listed IP and address normally reported by a slave is obtained # in the following way: # # IP: The address is auto detected by checking the peer address # of the socket used by the slave to connect with the master. # # Port: The port is communicated by the slave during the replication # handshake, and is normally the port that the slave is using to # list for connections. # # However when port forwarding or Network Address Translation (NAT) is # used, the slave may be actually reachable via different IP and port # pairs. The following two options can be used by a slave in order to # report to its master a specific set of IP and port, so that both INFO # and ROLE will report those values. # # There is no need to use both the options if you need to override just # the port or the IP address. # # slave-announce-ip 5.5.5.5 # slave-announce-port 1234 ################################## SECURITY ################################### # Require clients to issue AUTH before processing any other # commands.

By default # this limit is set to 10000 clients, however if the Redis server is not # able to configure the process file limit to allow for the specified limit # the max number of allowed clients is set to the current file limit # minus 32 (as Redis reserves a few file descriptors for internal uses). # # Once the limit is reached Redis will close all the new connections sending # an error 'max number of clients reached'. # # maxclients 10000 # Don't use more memory than the specified amount of bytes. # When the memory limit is reached Redis will try to remove keys # according to the eviction policy selected (see maxmemory-policy). # # If Redis can't remove keys according to the policy, or if the policy is # set to 'noeviction', Redis will start to reply with errors to commands # that would use more memory, like SET, LPUSH, and so on, and will continue # to reply to read-only commands like GET. # # This option is usually useful when using Redis as an LRU cache, or to set # a hard memory limit for an instance (using the 'noeviction' policy). # # WARNING: If you have slaves attached to an instance with maxmemory on, # the size of the output buffers needed to feed the slaves are subtracted # from the used memory count, so that network problems / resyncs will # not trigger a loop where keys are evicted, and in turn the output # buffer of slaves is full with DELs of keys evicted triggering the deletion # of more keys, and so forth until the database is completely emptied. # # In short... if you have slaves attached it is suggested that you set a lower # limit for maxmemory so that there is some free RAM on the system for slave # output buffers (but this is not needed if the policy is 'noeviction'). # # maxmemory # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory # is reached. You can select among five behaviors: # # volatile-lru -> remove the key with an expire set using an LRU algorithm # allkeys-lru -> remove any key according to the LRU algorithm # volatile-random -> remove a random key with an expire set # allkeys-random -> remove a random key, any key # volatile-ttl -> remove the key with the nearest expire time (minor TTL) # noeviction -> don't expire at all, just return an error on write operations # # Note: with any of the above policies, Redis will return an error on write # operations, when there are no suitable keys for eviction. # # At the date of writing these commands are: set setnx setex append # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby # getset mset msetnx exec sort # # The default is: # # maxmemory-policy noeviction # LRU and minimal TTL algorithms are not precise algorithms but approximated # algorithms (in order to save memory), so you can tune it for speed or # accuracy. For default Redis will check five keys and pick the one that was # used less recently, you can change the sample size using the following # configuration directive. # # The default of 5 produces good enough results. 10 Approximates very closely # true LRU but costs a bit more CPU. 3 is very fast but not very accurate. # # maxmemory-samples 5 ############################## APPEND ONLY MODE ############################### # By default Redis asynchronously dumps the dataset on disk. This mode is # good enough in many applications, but an issue with the Redis process or # a power outage may result into a few minutes of writes lost (depending on # the configured save points). # # The Append Only File is an alternative persistence mode that provides # much better durability. For instance using the default data fsync policy # (see later in the config file) Redis can lose just one second of writes in a # dramatic event like a server power outage, or a single write if something # wrong with the Redis process itself happens, but the operating system is # still running correctly. # # AOF and RDB persistence can be enabled at the same time without problems. # If the AOF is enabled on startup Redis will load the AOF, that is the file # with the better durability guarantees. # # Please check http://redis.io/topics/persistence for more information. appendonly no # The name of the append only file (default: "appendonly.aof") appendfilename "appendonly.aof" # The fsync() call tells the Operating System to actually write data on disk # instead of waiting for more data in the output buffer. Some OS will really flush # data on disk, some other OS will just try to do it ASAP. # # Redis supports three different modes: # # no: don't fsync, just let the OS flush the data when it wants. Faster. # always: fsync after every write to the append only log. Slow, Safest. # everysec: fsync only one time every second. Compromise. # # The default is "everysec", as that's usually the right compromise between # speed and data safety. It's up to you to understand if you can relax this to # "no" that will let the operating system flush the output buffer when # it wants, for better performances (but if you can live with the idea of # some data loss consider the default persistence mode that's snapshotting), # or on the contrary, use "always" that's very slow but a bit safer than # everysec. # # More details please check the following article: # http://antirez.com/post/redis-persistence-demystified.html # # If unsure, use "everysec". # appendfsync always appendfsync everysec # appendfsync no # When the AOF fsync policy is set to always or everysec, and a background # saving process (a background save or AOF log background rewriting) is # performing a lot of I/O against the disk, in some Linux configurations # Redis may block too long on the fsync() call.

In practical terms, this means that it is # possible to lose up to 30 seconds of log in the worst scenario (with the # default Linux settings). # # If you have latency problems turn this to "yes".

If the current size is # bigger than the specified percentage, the rewrite is triggered. Also # you need to specify a minimal size for the AOF file to be rewritten, this # is useful to avoid rewriting the AOF file even if the percentage increase # is reached but it is still pretty small. # # Specify a percentage of zero in order to disable the automatic AOF # rewrite feature. auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb # An AOF file may be found to be truncated at the end during the Redis # startup process, when the AOF data gets loaded back into memory. # This may happen when the system where Redis is running # crashes, especially when an ext4 filesystem is mounted without the # data=ordered option (however this can't happen when Redis itself # crashes or aborts but the operating system still works correctly). # # Redis can either exit with an error when this happens, or load as much # data as possible (the default now) and start if the AOF file is found # to be truncated at the end.

In order to start a Redis instance as a # cluster node enable the cluster support uncommenting the following: # # cluster-enabled yes # Every cluster node has a cluster configuration file. This file is not # intended to be edited by hand. It is created and updated by Redis nodes. # Every Redis Cluster node requires a different cluster configuration file. # Make sure that instances running in the same system do not have # overlapping cluster configuration file names. # # cluster-config-file nodes-6379.conf # Cluster node timeout is the amount of milliseconds a node must be unreachable # for it to be considered in failure state. # Most other internal time limits are multiple of the node timeout. # # cluster-node-timeout 15000 # A slave of a failing master will avoid to start a failover if its data # looks too old. # # There is no simple way for a slave to actually have a exact measure of # its "data age", so the following two checks are performed: # # 1) If there are multiple slaves able to failover, they exchange messages # in order to try to give an advantage to the slave with the best # replication offset (more data from the master processed). # Slaves will try to get their rank by offset, and apply to the start # of the failover a delay proportional to their rank. # # 2) Every single slave computes the time of the last interaction with # its master. This can be the last ping or command received (if the master # is still in the "connected" state), or the time that elapsed since the # disconnection with the master (if the replication link is currently down). # If the last interaction is too old, the slave will not try to failover # at all. # # The point "2" can be tuned by user. Specifically a slave will not perform # the failover if, since the last interaction with the master, the time # elapsed is greater than: # # (node-timeout * slave-validity-factor) + repl-ping-slave-period # # So for example if node-timeout is 30 seconds, and the slave-validity-factor # is 10, and assuming a default repl-ping-slave-period of 10 seconds, the # slave will not try to failover if it was not able to talk with the master # for longer than 310 seconds. # # A large slave-validity-factor may allow slaves with too old data to failover # a master, while a too small value may prevent the cluster from being able to # elect a slave at all. # # For maximum availability, it is possible to set the slave-validity-factor # to a value of 0, which means, that slaves will always try to failover the # master regardless of the last time they interacted with the master. # (However they'll always try to apply a delay proportional to their # offset rank). # # Zero is the only value able to guarantee that when all the partitions heal # the cluster will always be able to continue. # # cluster-slave-validity-factor 10 # Cluster slaves are able to migrate to orphaned masters, that are masters # that are left without working slaves. This improves the cluster ability # to resist to failures as otherwise an orphaned master can't be failed over # in case of failure if it has no working slaves. # # Slaves migrate to orphaned masters only if there are still at least a # given number of other working slaves for their old master. This number # is the "migration barrier". A migration barrier of 1 means that a slave # will migrate only if there is at least 1 other working slave for its master # and so forth. It usually reflects the number of slaves you want for every # master in your cluster. # # Default is 1 (slaves migrate only if their masters remain with at least # one slave). To disable migration just set it to a very large value. # A value of 0 can be set but is useful only for debugging and dangerous # in production. # # cluster-migration-barrier 1 # By default Redis Cluster nodes stop accepting queries if they detect there # is at least an hash slot uncovered (no available node is serving it). # This way if the cluster is partially down (for example a range of hash slots # are no longer covered) all the cluster becomes, eventually, unavailable. # It automatically returns available as soon as all the slots are covered again. # # However sometimes you want the subset of the cluster which is working, # to continue to accept queries for the part of the key space that is still # covered. In order to do so, just set the cluster-require-full-coverage # option to no. # # cluster-require-full-coverage yes # In order to setup your cluster make sure to read the documentation # available at http://redis.io web site. ################################## SLOW LOG ################################### # The Redis Slow Log is a system to log queries that exceeded a specified # execution time. The execution time does not include the I/O operations # like talking with the client, sending the reply and so forth, # but just the time needed to actually execute the command (this is the only # stage of command execution where the thread is blocked and can not serve # other requests in the meantime). # # You can configure the slow log with two parameters: one tells Redis # what is the execution time, in microseconds, to exceed in order for the # command to get logged, and the other parameter is the length of the # slow log. When a new command is logged the oldest one is removed from the # queue of logged commands. # The following time is expressed in microseconds, so 1000000 is equivalent # to one second.

The limit includes the # 16 bytes header. When an HyperLogLog using the sparse representation crosses # this limit, it is converted into the dense representation. # # A value greater than 16000 is totally useless, since at that point the # dense representation is more memory efficient. # # The suggested value is ~ 3000 in order to have the benefits of # the space efficient encoding without slowing down too much PFADD, # which is O(N) with the sparse encoding. The value can be raised to # ~ 10000 when CPU is not a concern, but space is, and the data set is # composed of many HyperLogLogs with cardinality in the 0 - 15000 range. hll-sparse-max-bytes 3000 # Active rehashing uses 1 millisecond every 100 milliseconds of CPU time in # order to help rehashing the main Redis hash table (the one mapping top-level # keys to values). The hash table implementation Redis uses (see dict.c) # performs a lazy rehashing: the more operation you run into a hash table # that is rehashing, the more rehashing "steps" are performed, so if the # server is idle the rehashing is never complete and some more memory is used # by the hash table. # # The default is to use this millisecond 10 times every second in order to # actively rehash the main dictionaries, freeing memory when possible. # # If unsure: # use "activerehashing no" if you have hard latency requirements and it is # not a good thing in your environment that Redis can reply from time to time # to queries with 2 milliseconds delay. # # use "activerehashing yes" if you don't have such hard requirements but # want to free memory asap when possible. activerehashing yes # The client output buffer limits can be used to force disconnection of clients # that are not reading data from the server fast enough for some reason (a # common reason is that a Pub/Sub client can't consume messages as fast as the # publisher can produce them). # # The limit can be set differently for the three different classes of clients: # # normal -> normal clients including MONITOR clients # slave -> slave clients # pubsub -> clients subscribed to at least one pubsub channel or pattern # # The syntax of every client-output-buffer-limit directive is the following: # # client-output-buffer-limit # # A client is immediately disconnected once the hard limit is reached, or if # the soft limit is reached and remains reached for the specified number of # seconds (continuously). # So for instance if the hard limit is 32 megabytes and the soft limit is # 16 megabytes / 10 seconds, the client will get disconnected immediately # if the size of the output buffers reach 32 megabytes, but will also get # disconnected if the client reaches 16 megabytes and continuously overcomes # the limit for 10 seconds. # # By default normal clients are not limited because they don't receive data # without asking (in a push way), but just after a request, so only # asynchronous clients may create a scenario where data is requested faster # than it can read. # # Instead there is a default limit for pubsub and slave clients, since # subscribers and slaves receive data in a push fashion. # # Both the hard or the soft limit can be disabled by setting them to zero. client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 # Redis calls an internal function to perform many background tasks, like # closing connections of clients in timeout, purging expired keys that are # never requested, and so forth. # # Not all tasks are performed with the same frequency, but Redis checks for # tasks to perform according to the specified "hz" value. # # By default "hz" is set to 10.

This collision resolution code allows nodes to automatically * end with a different configEpoch at startup automatically. * * In all the cases, we want a mechanism that resolves this issue automatically * as a safeguard.

The allocated space is suitably aligned (after possible pointer coercion) for storage of any type of object. The calloc function allocates space for number objects, each size bytes in length. The result is identical to calling malloc with an argument of number * size, with the exception that the allocated memory is explicitly initialized to zero bytes. The posix_memalign function allocates size bytes of memory such that the allocation's base address is a multiple of alignment, and returns the allocation in the value pointed to by ptr. The requested alignment must be a power of 2 at least as large as sizeof(void *). The aligned_alloc function allocates size bytes of memory such that the allocation's base address is a multiple of alignment. The requested alignment must be a power of 2. Behavior is undefined if size is not an integral multiple of alignment. The realloc function changes the size of the previously allocated memory referenced by ptr to size bytes. The contents of the memory are unchanged up to the lesser of the new and old sizes. If the new size is larger, the contents of the newly allocated portion of the memory are undefined. Upon success, the memory referenced by ptr is freed and a pointer to the newly allocated memory is returned. Note that realloc may move the memory allocation, resulting in a different return value than ptr. If ptr is NULL, the realloc function behaves identically to malloc for the specified size. The free function causes the allocated memory referenced by ptr to be made available for future allocations. If ptr is NULL, no action occurs. Non-standard API The mallocx, rallocx, xallocx, sallocx, dallocx, sdallocx, and nallocx functions all have a flags argument that can be used to specify options. The functions only check the options that are contextually relevant. Use bitwise or (|) operations to specify one or more of the following: MALLOCX_LG_ALIGN(la) Align the memory allocation to start at an address that is a multiple of (1 << la). This macro does not validate that la is within the valid range. MALLOCX_ALIGN(a) Align the memory allocation to start at an address that is a multiple of a, where a is a power of two. This macro does not validate that a is a power of 2. MALLOCX_ZERO Initialize newly allocated memory to contain zero bytes. In the growing reallocation case, the real size prior to reallocation defines the boundary between untouched bytes and those that are initialized to contain zero bytes. If this macro is absent, newly allocated memory is uninitialized. MALLOCX_TCACHE(tc) Use the thread-specific cache (tcache) specified by the identifier tc, which must have been acquired via the tcache.create mallctl. This macro does not validate that tc specifies a valid identifier. MALLOCX_TCACHE_NONE Do not use a thread-specific cache (tcache). Unless MALLOCX_TCACHE(tc) or MALLOCX_TCACHE_NONE is specified, an automatically managed tcache will be used under many circumstances. This macro cannot be used in the same flags argument as MALLOCX_TCACHE(tc). MALLOCX_ARENA(a) Use the arena specified by the index a. This macro has no effect for regions that were allocated via an arena other than the one specified. This macro does not validate that a specifies an arena index in the valid range. The mallocx function allocates at least size bytes of memory, and returns a pointer to the base address of the allocation. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The rallocx function resizes the allocation at ptr to be at least size bytes, and returns a pointer to the base address of the resulting allocation, which may or may not have moved from its original location. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The xallocx function resizes the allocation at ptr in place to be at least size bytes, and returns the real size of the allocation. If extra is non-zero, an attempt is made to resize the allocation to be at least (size + extra) bytes, though inability to allocate the extra byte(s) will not by itself result in failure to resize. Behavior is undefined if size is 0, or if (size + extra > SIZE_T_MAX). The sallocx function returns the real size of the allocation at ptr. The dallocx function causes the memory referenced by ptr to be made available for future allocations. The sdallocx function is an extension of dallocx with a size parameter to allow the caller to pass in the allocation size as an optimization. The minimum valid input size is the original requested size of the allocation, and the maximum valid input size is the corresponding value returned by nallocx or sallocx. The nallocx function allocates no memory, but it performs the same size computation as the mallocx function, and returns the real size of the allocation that would result from the equivalent mallocx function call. Behavior is undefined if size is 0, or if request size overflows due to size class and/or alignment constraints. The mallctl function provides a general interface for introspecting the memory allocator, as well as setting modifiable parameters and triggering actions. The period-separated name argument specifies a location in a tree-structured namespace; see the section for documentation on the tree contents. To read a value, pass a pointer via oldp to adequate space to contain the value, and a pointer to its length via oldlenp; otherwise pass NULL and NULL. Similarly, to write a value, pass a pointer to the value via newp, and its length via newlen; otherwise pass NULL and 0. The mallctlnametomib function provides a way to avoid repeated name lookups for applications that repeatedly query the same portion of the namespace, by translating a name to a “Management Information Base” (MIB) that can be passed repeatedly to mallctlbymib. Upon successful return from mallctlnametomib, mibp contains an array of *miblenp integers, where *miblenp is the lesser of the number of components in name and the input value of *miblenp. Thus it is possible to pass a *miblenp that is smaller than the number of period-separated name components, which results in a partial MIB that can be used as the basis for constructing a complete MIB. For name components that are integers (e.g. the 2 in arenas.bin.2.size), the corresponding MIB component will always be that integer. Therefore, it is legitimate to construct code like the following: The malloc_stats_print function writes human-readable summary statistics via the write_cb callback function pointer and cbopaque data passed to write_cb, or malloc_message if write_cb is NULL. This function can be called repeatedly. General information that never changes during execution can be omitted by specifying "g" as a character within the opts string. Note that malloc_message uses the mallctl* functions internally, so inconsistent statistics can be reported if multiple threads use these functions simultaneously. If is specified during configuration, “m” and “a” can be specified to omit merged arena and per arena statistics, respectively; “b”, “l”, and “h” can be specified to omit per size class statistics for bins, large objects, and huge objects, respectively. Unrecognized characters are silently ignored. Note that thread caching may prevent some statistics from being completely up to date, since extra locking would be required to merge counters that track thread cache operations. The malloc_usable_size function returns the usable size of the allocation pointed to by ptr. The return value may be larger than the size that was requested during allocation. The malloc_usable_size function is not a mechanism for in-place realloc; rather it is provided solely as a tool for introspection purposes. Any discrepancy between the requested allocation size and the size reported by malloc_usable_size should not be depended on, since such behavior is entirely implementation-dependent. TUNING Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile- or run-time. The string pointed to by the global variable malloc_conf, the “name” of the file referenced by the symbolic link named /etc/malloc.conf, and the value of the environment variable MALLOC_CONF, will be interpreted, in that order, from left to right as options. Note that malloc_conf may be read before main is entered, so the declaration of malloc_conf should specify an initializer that contains the final value to be read by jemalloc. malloc_conf is a compile-time setting, whereas /etc/malloc.conf and MALLOC_CONF can be safely set any time prior to program invocation. An options string is a comma-separated list of option:value pairs. There is one key corresponding to each opt.* mallctl (see the section for options documentation). For example, abort:true,narenas:1 sets the opt.abort and opt.narenas options. Some options have boolean values (true/false), others have integer values (base 8, 10, or 16, depending on prefix), and yet others have raw string values. IMPLEMENTATION NOTES Traditionally, allocators have used sbrk 2 to obtain memory, which is suboptimal for several reasons, including race conditions, increased fragmentation, and artificial limitations on maximum usable memory. If sbrk 2 is supported by the operating system, this allocator uses both mmap 2 and sbrk 2, in that order of preference; otherwise only mmap 2 is used. This allocator uses multiple arenas in order to reduce lock contention for threaded programs on multi-processor systems. This works well with regard to threading scalability, but incurs some costs. There is a small fixed per-arena overhead, and additionally, arenas manage memory completely independently of each other, which means a small fixed increase in overall memory fragmentation. These overheads are not generally an issue, given the number of arenas normally used. Note that using substantially more arenas than the default is not likely to improve performance, mainly due to reduced cache performance. However, it may make sense to reduce the number of arenas if an application does not make much use of the allocation functions. In addition to multiple arenas, unless is specified during configuration, this allocator supports thread-specific caching for small and large objects, in order to make it possible to completely avoid synchronization for most allocation requests. Such caching allows very fast allocation in the common case, but it increases memory usage and fragmentation, since a bounded number of objects can remain allocated in each thread cache. Memory is conceptually broken into equal-sized chunks, where the chunk size is a power of two that is greater than the page size. Chunks are always aligned to multiples of the chunk size. This alignment makes it possible to find metadata for user objects very quickly. User objects are broken into three categories according to size: small, large, and huge. Small and large objects are managed entirely by arenas; huge objects are additionally aggregated in a single data structure that is shared by all threads. Huge objects are typically used by applications infrequently enough that this single data structure is not a scalability issue. Each chunk that is managed by an arena tracks its contents as runs of contiguous pages (unused, backing a set of small objects, or backing one large object). The combination of chunk alignment and chunk page maps makes it possible to determine all metadata regarding small and large allocations in constant time. Small objects are managed in groups by page runs. Each run maintains a bitmap to track which regions are in use. Allocation requests that are no more than half the quantum (8 or 16, depending on architecture) are rounded up to the nearest power of two that is at least sizeof(double). All other object size classes are multiples of the quantum, spaced such that there are four size classes for each doubling in size, which limits internal fragmentation to approximately 20% for all but the smallest size classes. Small size classes are smaller than four times the page size, large size classes are smaller than the chunk size (see the opt.lg_chunk option), and huge size classes extend from the chunk size up to one size class less than the full address space size. Allocations are packed tightly together, which can be an issue for multi-threaded applications. If you need to assure that allocations do not suffer from cacheline sharing, round your allocation requests up to the nearest multiple of the cacheline size, or specify cacheline alignment when allocating. The realloc, rallocx, and xallocx functions may resize allocations without moving them under limited circumstances. Unlike the *allocx API, the standard API does not officially round up the usable size of an allocation to the nearest size class, so technically it is necessary to call realloc to grow e.g. a 9-byte allocation to 16 bytes, or shrink a 16-byte allocation to 9 bytes. Growth and shrinkage trivially succeeds in place as long as the pre-size and post-size both round up to the same size class. No other API guarantees are made regarding in-place resizing, but the current implementation also tries to resize large and huge allocations in place, as long as the pre-size and post-size are both large or both huge. In such cases shrinkage always succeeds for large size classes, but for huge size classes the chunk allocator must support splitting (see arena.<i>.chunk_hooks). Growth only succeeds if the trailing memory is currently available, and additionally for huge size classes the chunk allocator must support merging. Assuming 2 MiB chunks, 4 KiB pages, and a 16-byte quantum on a 64-bit system, the size classes in each category are as shown in .

MALLCTL NAMESPACE The following names are defined in the namespace accessible via the mallctl* functions. Value types are specified in parentheses, their readable/writable statuses are encoded as rw, r-, -w, or --, and required build configuration flags follow, if any. A name element encoded as <i> or <j> indicates an integer component, where the integer varies from 0 to some upper value that must be determined via introspection. In the case of stats.arenas.<i>.*, <i> equal to arenas.narenas can be used to access the summation of statistics from all arenas. Take special note of the epoch mallctl, which controls refreshing of cached dynamic statistics. version (const char *) r- Return the jemalloc version string. epoch (uint64_t) rw If a value is passed in, refresh the data from which the mallctl* functions report values, and increment the epoch. Return the current epoch. This is useful for detecting whether another thread caused a refresh. config.cache_oblivious (bool) r- was specified during build configuration. config.debug (bool) r- was specified during build configuration. config.fill (bool) r- was specified during build configuration. config.lazy_lock (bool) r- was specified during build configuration. config.munmap (bool) r- was specified during build configuration. config.prof (bool) r- was specified during build configuration. config.prof_libgcc (bool) r- was not specified during build configuration. config.prof_libunwind (bool) r- was specified during build configuration. config.stats (bool) r- was specified during build configuration. config.tcache (bool) r- was not specified during build configuration. config.tls (bool) r- was not specified during build configuration. config.utrace (bool) r- was specified during build configuration. config.valgrind (bool) r- was specified during build configuration. config.xmalloc (bool) r- was specified during build configuration. opt.abort (bool) r- Abort-on-warning enabled/disabled. If true, most warnings are fatal. The process will call abort 3 in these cases. This option is disabled by default unless is specified during configuration, in which case it is enabled by default. opt.dss (const char *) r- dss (sbrk 2) allocation precedence as related to mmap 2 allocation. The following settings are supported if sbrk 2 is supported by the operating system: “disabled”, “primary”, and “secondary”; otherwise only “disabled” is supported. The default is “secondary” if sbrk 2 is supported by the operating system; “disabled” otherwise. opt.lg_chunk (size_t) r- Virtual memory chunk size (log base 2). If a chunk size outside the supported size range is specified, the size is silently clipped to the minimum/maximum supported size. The default chunk size is 2 MiB (2^21). opt.narenas (size_t) r- Maximum number of arenas to use for automatic multiplexing of threads and arenas. The default is four times the number of CPUs, or one if there is a single CPU. opt.lg_dirty_mult (ssize_t) r- Per-arena minimum ratio (log base 2) of active to dirty pages. Some dirty unused pages may be allowed to accumulate, within the limit set by the ratio (or one chunk worth of dirty pages, whichever is greater), before informing the kernel about some of those pages via madvise 2 or a similar system call. This provides the kernel with sufficient information to recycle dirty pages if physical memory becomes scarce and the pages remain unused. The default minimum ratio is 8:1 (2^3:1); an option value of -1 will disable dirty page purging. See arenas.lg_dirty_mult and arena.<i>.lg_dirty_mult for related dynamic control options. opt.stats_print (bool) r- Enable/disable statistics printing at exit. If enabled, the malloc_stats_print function is called at program exit via an atexit 3 function. If is specified during configuration, this has the potential to cause deadlock for a multi-threaded process that exits while one or more threads are executing in the memory allocation functions. Furthermore, atexit may allocate memory during application initialization and then deadlock internally when jemalloc in turn calls atexit, so this option is not univerally usable (though the application can register its own atexit function with equivalent functionality). Therefore, this option should only be used with care; it is primarily intended as a performance tuning aid during application development. This option is disabled by default. opt.junk (const char *) r- [] Junk filling. If set to "alloc", each byte of uninitialized allocated memory will be initialized to 0xa5. If set to "free", all deallocated memory will be initialized to 0x5a. If set to "true", both allocated and deallocated memory will be initialized, and if set to "false", junk filling be disabled entirely. This is intended for debugging and will impact performance negatively. This option is "false" by default unless is specified during configuration, in which case it is "true" by default unless running inside Valgrind. opt.quarantine (size_t) r- [] Per thread quarantine size in bytes. If non-zero, each thread maintains a FIFO object quarantine that stores up to the specified number of bytes of memory. The quarantined memory is not freed until it is released from quarantine, though it is immediately junk-filled if the opt.junk option is enabled. This feature is of particular use in combination with Valgrind, which can detect attempts to access quarantined objects. This is intended for debugging and will impact performance negatively. The default quarantine size is 0 unless running inside Valgrind, in which case the default is 16 MiB. opt.redzone (bool) r- [] Redzones enabled/disabled. If enabled, small allocations have redzones before and after them. Furthermore, if the opt.junk option is enabled, the redzones are checked for corruption during deallocation. However, the primary intended purpose of this feature is to be used in combination with Valgrind, which needs redzones in order to do effective buffer overflow/underflow detection. This option is intended for debugging and will impact performance negatively. This option is disabled by default unless running inside Valgrind. opt.zero (bool) r- [] Zero filling enabled/disabled. If enabled, each byte of uninitialized allocated memory will be initialized to 0. Note that this initialization only happens once for each byte, so realloc and rallocx calls do not zero memory that was previously allocated. This is intended for debugging and will impact performance negatively. This option is disabled by default. opt.utrace (bool) r- [] Allocation tracing based on utrace 2 enabled/disabled. This option is disabled by default. opt.xmalloc (bool) r- [] Abort-on-out-of-memory enabled/disabled. If enabled, rather than returning failure for any allocation function, display a diagnostic message on STDERR_FILENO and cause the program to drop core (using abort 3). If an application is designed to depend on this behavior, set the option at compile time by including the following in the source code: This option is disabled by default. opt.tcache (bool) r- [] Thread-specific caching (tcache) enabled/disabled. When there are multiple threads, each thread uses a tcache for objects up to a certain size. Thread-specific caching allows many allocations to be satisfied without performing any thread synchronization, at the cost of increased memory use. See the opt.lg_tcache_max option for related tuning information. This option is enabled by default unless running inside Valgrind, in which case it is forcefully disabled. opt.lg_tcache_max (size_t) r- [] Maximum size class (log base 2) to cache in the thread-specific cache (tcache). At a minimum, all small size classes are cached, and at a maximum all large size classes are cached. The default maximum is 32 KiB (2^15). opt.prof (bool) r- [] Memory profiling enabled/disabled. If enabled, profile memory allocation activity. See the opt.prof_active option for on-the-fly activation/deactivation. See the opt.lg_prof_sample option for probabilistic sampling control. See the opt.prof_accum option for control of cumulative sample reporting. See the opt.lg_prof_interval option for information on interval-triggered profile dumping, the opt.prof_gdump option for information on high-water-triggered profile dumping, and the opt.prof_final option for final profile dumping. Profile output is compatible with the jeprof command, which is based on the pprof that is developed as part of the gperftools package. opt.prof_prefix (const char *) r- [] Filename prefix for profile dumps. If the prefix is set to the empty string, no automatic dumps will occur; this is primarily useful for disabling the automatic final heap dump (which also disables leak reporting, if enabled). The default prefix is jeprof. opt.prof_active (bool) r- [] Profiling activated/deactivated. This is a secondary control mechanism that makes it possible to start the application with profiling enabled (see the opt.prof option) but inactive, then toggle profiling at any time during program execution with the prof.active mallctl. This option is enabled by default. opt.prof_thread_active_init (bool) r- [] Initial setting for thread.prof.active in newly created threads. The initial setting for newly created threads can also be changed during execution via the prof.thread_active_init mallctl. This option is enabled by default. opt.lg_prof_sample (size_t) r- [] Average interval (log base 2) between allocation samples, as measured in bytes of allocation activity. Increasing the sampling interval decreases profile fidelity, but also decreases the computational overhead. The default sample interval is 512 KiB (2^19 B). opt.prof_accum (bool) r- [] Reporting of cumulative object/byte counts in profile dumps enabled/disabled. If this option is enabled, every unique backtrace must be stored for the duration of execution. Depending on the application, this can impose a large memory overhead, and the cumulative counts are not always of interest. This option is disabled by default. opt.lg_prof_interval (ssize_t) r- [] Average interval (log base 2) between memory profile dumps, as measured in bytes of allocation activity. The actual interval between dumps may be sporadic because decentralized allocation counters are used to avoid synchronization bottlenecks. Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.i<iseq>.heap, where <prefix> is controlled by the opt.prof_prefix option. By default, interval-triggered profile dumping is disabled (encoded as -1). opt.prof_gdump (bool) r- [] Set the initial state of prof.gdump, which when enabled triggers a memory profile dump every time the total virtual memory exceeds the previous maximum. This option is disabled by default. opt.prof_final (bool) r- [] Use an atexit 3 function to dump final memory usage to a file named according to the pattern <prefix>.<pid>.<seq>.f.heap, where <prefix> is controlled by the opt.prof_prefix option. Note that atexit may allocate memory during application initialization and then deadlock internally when jemalloc in turn calls atexit, so this option is not univerally usable (though the application can register its own atexit function with equivalent functionality). This option is disabled by default. opt.prof_leak (bool) r- [] Leak reporting enabled/disabled. If enabled, use an atexit 3 function to report memory leaks detected by allocation sampling. See the opt.prof option for information on analyzing heap profile output. This option is disabled by default. thread.arena (unsigned) rw Get or set the arena associated with the calling thread. If the specified arena was not initialized beforehand (see the arenas.initialized mallctl), it will be automatically initialized as a side effect of calling this interface. thread.allocated (uint64_t) r- [] Get the total number of bytes ever allocated by the calling thread. This counter has the potential to wrap around; it is up to the application to appropriately interpret the counter in such cases. thread.allocatedp (uint64_t *) r- [] Get a pointer to the the value that is returned by the thread.allocated mallctl. This is useful for avoiding the overhead of repeated mallctl* calls. thread.deallocated (uint64_t) r- [] Get the total number of bytes ever deallocated by the calling thread. This counter has the potential to wrap around; it is up to the application to appropriately interpret the counter in such cases. thread.deallocatedp (uint64_t *) r- [] Get a pointer to the the value that is returned by the thread.deallocated mallctl. This is useful for avoiding the overhead of repeated mallctl* calls. thread.tcache.enabled (bool) rw [] Enable/disable calling thread's tcache. The tcache is implicitly flushed as a side effect of becoming disabled (see thread.tcache.flush). thread.tcache.flush (void) -- [] Flush calling thread's thread-specific cache (tcache). This interface releases all cached objects and internal data structures associated with the calling thread's tcache. Ordinarily, this interface need not be called, since automatic periodic incremental garbage collection occurs, and the thread cache is automatically discarded when a thread exits. However, garbage collection is triggered by allocation activity, so it is possible for a thread that stops allocating/deallocating to retain its cache indefinitely, in which case the developer may find manual flushing useful. thread.prof.name (const char *) r- or -w [] Get/set the descriptive name associated with the calling thread in memory profile dumps. An internal copy of the name string is created, so the input string need not be maintained after this interface completes execution. The output string of this interface should be copied for non-ephemeral uses, because multiple implementation details can cause asynchronous string deallocation. Furthermore, each invocation of this interface can only read or write; simultaneous read/write is not supported due to string lifetime limitations. The name string must nil-terminated and comprised only of characters in the sets recognized by isgraph 3 and isblank 3. thread.prof.active (bool) rw [] Control whether sampling is currently active for the calling thread. This is an activation mechanism in addition to prof.active; both must be active for the calling thread to sample. This flag is enabled by default. tcache.create (unsigned) r- [] Create an explicit thread-specific cache (tcache) and return an identifier that can be passed to the MALLOCX_TCACHE(tc) macro to explicitly use the specified cache rather than the automatically managed one that is used by default. Each explicit cache can be used by only one thread at a time; the application must assure that this constraint holds. tcache.flush (unsigned) -w [] Flush the specified thread-specific cache (tcache). The same considerations apply to this interface as to thread.tcache.flush, except that the tcache will never be automatically be discarded. tcache.destroy (unsigned) -w [] Flush the specified thread-specific cache (tcache) and make the identifier available for use during a future tcache creation. arena.<i>.purge (void) -- Purge unused dirty pages for arena <i>, or for all arenas if <i> equals arenas.narenas. arena.<i>.dss (const char *) rw Set the precedence of dss allocation as related to mmap allocation for arena <i>, or for all arenas if <i> equals arenas.narenas. See opt.dss for supported settings. arena.<i>.lg_dirty_mult (ssize_t) rw Current per-arena minimum ratio (log base 2) of active to dirty pages for arena <i>. Each time this interface is set and the ratio is increased, pages are synchronously purged as necessary to impose the new ratio. See opt.lg_dirty_mult for additional information. arena.<i>.chunk_hooks (chunk_hooks_t) rw Get or set the chunk management hook functions for arena <i>. The functions must be capable of operating on all extant chunks associated with arena <i>, usually by passing unknown chunks to the replaced functions. In practice, it is feasible to control allocation for arenas created via arenas.extend such that all chunks originate from an application-supplied chunk allocator (by setting custom chunk hook functions just after arena creation), but the automatically created arenas may have already created chunks prior to the application having an opportunity to take over chunk allocation. The chunk_hooks_t structure comprises function pointers which are described individually below. jemalloc uses these functions to manage chunk lifetime, which starts off with allocation of mapped committed memory, in the simplest case followed by deallocation. However, there are performance and platform reasons to retain chunks for later reuse. Cleanup attempts cascade from deallocation to decommit to purging, which gives the chunk management functions opportunities to reject the most permanent cleanup operations in favor of less permanent (and often less costly) operations. The chunk splitting and merging operations can also be opted out of, but this is mainly intended to support platforms on which virtual memory mappings provided by the operating system kernel do not automatically coalesce and split, e.g. Windows. typedef void *(chunk_alloc_t) void *chunk size_t size size_t alignment bool *zero bool *commit unsigned arena_ind A chunk allocation function conforms to the chunk_alloc_t type and upon success returns a pointer to size bytes of mapped memory on behalf of arena arena_ind such that the chunk's base address is a multiple of alignment, as well as setting *zero to indicate whether the chunk is zeroed and *commit to indicate whether the chunk is committed. Upon error the function returns NULL and leaves *zero and *commit unmodified. The size parameter is always a multiple of the chunk size. The alignment parameter is always a power of two at least as large as the chunk size. Zeroing is mandatory if *zero is true upon function entry. Committing is mandatory if *commit is true upon function entry. If chunk is not NULL, the returned pointer must be chunk on success or NULL on error. Committed memory may be committed in absolute terms as on a system that does not overcommit, or in implicit terms as on a system that overcommits and satisfies physical memory needs on demand via soft page faults. Note that replacing the default chunk allocation function makes the arena's arena.<i>.dss setting irrelevant. typedef bool (chunk_dalloc_t) void *chunk size_t size bool committed unsigned arena_ind A chunk deallocation function conforms to the chunk_dalloc_t type and deallocates a chunk of given size with committed/decommited memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates opt-out from deallocation; the virtual memory mapping associated with the chunk remains mapped, in the same commit state, and available for future use, in which case it will be automatically retained for later reuse. typedef bool (chunk_commit_t) void *chunk size_t size size_t offset size_t length unsigned arena_ind A chunk commit function conforms to the chunk_commit_t type and commits zeroed physical memory to back pages within a chunk of given size at offset bytes, extending for length on behalf of arena arena_ind, returning false upon success. Committed memory may be committed in absolute terms as on a system that does not overcommit, or in implicit terms as on a system that overcommits and satisfies physical memory needs on demand via soft page faults. If the function returns true, this indicates insufficient physical memory to satisfy the request. typedef bool (chunk_decommit_t) void *chunk size_t size size_t offset size_t length unsigned arena_ind A chunk decommit function conforms to the chunk_decommit_t type and decommits any physical memory that is backing pages within a chunk of given size at offset bytes, extending for length on behalf of arena arena_ind, returning false upon success, in which case the pages will be committed via the chunk commit function before being reused. If the function returns true, this indicates opt-out from decommit; the memory remains committed and available for future use, in which case it will be automatically retained for later reuse. typedef bool (chunk_purge_t) void *chunk size_tsize size_t offset size_t length unsigned arena_ind A chunk purge function conforms to the chunk_purge_t type and optionally discards physical pages within the virtual memory mapping associated with chunk of given size at offset bytes, extending for length on behalf of arena arena_ind, returning false if pages within the purged virtual memory range will be zero-filled the next time they are accessed. typedef bool (chunk_split_t) void *chunk size_t size size_t size_a size_t size_b bool committed unsigned arena_ind A chunk split function conforms to the chunk_split_t type and optionally splits chunk of given size into two adjacent chunks, the first of size_a bytes, and the second of size_b bytes, operating on committed/decommitted memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates that the chunk remains unsplit and therefore should continue to be operated on as a whole. typedef bool (chunk_merge_t) void *chunk_a size_t size_a void *chunk_b size_t size_b bool committed unsigned arena_ind A chunk merge function conforms to the chunk_merge_t type and optionally merges adjacent chunks, chunk_a of given size_a and chunk_b of given size_b into one contiguous chunk, operating on committed/decommitted memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates that the chunks remain distinct mappings and therefore should continue to be operated on independently. arenas.narenas (unsigned) r- Current limit on number of arenas. arenas.initialized (bool *) r- An array of arenas.narenas booleans. Each boolean indicates whether the corresponding arena is initialized. arenas.lg_dirty_mult (ssize_t) rw Current default per-arena minimum ratio (log base 2) of active to dirty pages, used to initialize arena.<i>.lg_dirty_mult during arena creation. See opt.lg_dirty_mult for additional information. arenas.quantum (size_t) r- Quantum size. arenas.page (size_t) r- Page size. arenas.tcache_max (size_t) r- [] Maximum thread-cached size class. arenas.nbins (unsigned) r- Number of bin size classes. arenas.nhbins (unsigned) r- [] Total number of thread cache bin size classes. arenas.bin.<i>.size (size_t) r- Maximum size supported by size class. arenas.bin.<i>.nregs (uint32_t) r- Number of regions per page run. arenas.bin.<i>.run_size (size_t) r- Number of bytes per page run. arenas.nlruns (unsigned) r- Total number of large size classes. arenas.lrun.<i>.size (size_t) r- Maximum size supported by this large size class. arenas.nhchunks (unsigned) r- Total number of huge size classes. arenas.hchunk.<i>.size (size_t) r- Maximum size supported by this huge size class. arenas.extend (unsigned) r- Extend the array of arenas by appending a new arena, and returning the new arena index. prof.thread_active_init (bool) rw [] Control the initial setting for thread.prof.active in newly created threads. See the opt.prof_thread_active_init option for additional information. prof.active (bool) rw [] Control whether sampling is currently active. See the opt.prof_active option for additional information, as well as the interrelated thread.prof.active mallctl. prof.dump (const char *) -w [] Dump a memory profile to the specified file, or if NULL is specified, to a file according to the pattern <prefix>.<pid>.<seq>.m<mseq>.heap, where <prefix> is controlled by the opt.prof_prefix option. prof.gdump (bool) rw [] When enabled, trigger a memory profile dump every time the total virtual memory exceeds the previous maximum. Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.u<useq>.heap, where <prefix> is controlled by the opt.prof_prefix option. prof.reset (size_t) -w [] Reset all memory profile statistics, and optionally update the sample rate (see opt.lg_prof_sample and prof.lg_sample). prof.lg_sample (size_t) r- [] Get the current sample rate (see opt.lg_prof_sample). prof.interval (uint64_t) r- [] Average number of bytes allocated between inverval-based profile dumps. See the opt.lg_prof_interval option for additional information. stats.cactive (size_t *) r- [] Pointer to a counter that contains an approximate count of the current number of bytes in active pages. The estimate may be high, but never low, because each arena rounds up when computing its contribution to the counter. Note that the epoch mallctl has no bearing on this counter. Furthermore, counter consistency is maintained via atomic operations, so it is necessary to use an atomic operation in order to guarantee a consistent read when dereferencing the pointer. stats.allocated (size_t) r- [] Total number of bytes allocated by the application. stats.active (size_t) r- [] Total number of bytes in active pages allocated by the application. This is a multiple of the page size, and greater than or equal to stats.allocated. This does not include stats.arenas.<i>.pdirty, nor pages entirely devoted to allocator metadata. stats.metadata (size_t) r- [] Total number of bytes dedicated to metadata, which comprise base allocations used for bootstrap-sensitive internal allocator data structures, arena chunk headers (see stats.arenas.<i>.metadata.mapped), and internal allocations (see stats.arenas.<i>.metadata.allocated). stats.resident (size_t) r- [] Maximum number of bytes in physically resident data pages mapped by the allocator, comprising all pages dedicated to allocator metadata, pages backing active allocations, and unused dirty pages. This is a maximum rather than precise because pages may not actually be physically resident if they correspond to demand-zeroed virtual memory that has not yet been touched. This is a multiple of the page size, and is larger than stats.active. stats.mapped (size_t) r- [] Total number of bytes in active chunks mapped by the allocator. This is a multiple of the chunk size, and is larger than stats.active. This does not include inactive chunks, even those that contain unused dirty pages, which means that there is no strict ordering between this and stats.resident. stats.arenas.<i>.dss (const char *) r- dss (sbrk 2) allocation precedence as related to mmap 2 allocation. See opt.dss for details. stats.arenas.<i>.lg_dirty_mult (ssize_t) r- Minimum ratio (log base 2) of active to dirty pages. See opt.lg_dirty_mult for details. stats.arenas.<i>.nthreads (unsigned) r- Number of threads currently assigned to arena. stats.arenas.<i>.pactive (size_t) r- Number of pages in active runs. stats.arenas.<i>.pdirty (size_t) r- Number of pages within unused runs that are potentially dirty, and for which madvise... MADV_DONTNEED or similar has not been called. stats.arenas.<i>.mapped (size_t) r- [] Number of mapped bytes. stats.arenas.<i>.metadata.mapped (size_t) r- [] Number of mapped bytes in arena chunk headers, which track the states of the non-metadata pages. stats.arenas.<i>.metadata.allocated (size_t) r- [] Number of bytes dedicated to internal allocations.

DEBUGGING MALLOC PROBLEMS When debugging, it is a good idea to configure/build jemalloc with the and options, and recompile the program with suitable options and symbols for debugger support. When so configured, jemalloc incorporates a wide variety of run-time assertions that catch application errors such as double-free, write-after-free, etc. Programs often accidentally depend on “uninitialized” memory actually being filled with zero bytes. Junk filling (see the opt.junk option) tends to expose such bugs in the form of obviously incorrect results and/or coredumps. Conversely, zero filling (see the opt.zero option) eliminates the symptoms of such bugs. Between these two options, it is usually possible to quickly detect, diagnose, and eliminate such bugs. This implementation does not provide much detail about the problems it detects, because the performance impact for storing such information would be prohibitive. However, jemalloc does integrate with the most excellent Valgrind tool if the configuration option is enabled. DIAGNOSTIC MESSAGES If any of the memory allocation/deallocation functions detect an error or warning condition, a message will be printed to file descriptor STDERR_FILENO. Errors will result in the process dumping core. If the opt.abort option is set, most warnings are treated as errors. The malloc_message variable allows the programmer to override the function which emits the text strings forming the errors and warnings if for some reason the STDERR_FILENO file descriptor is not suitable for this. malloc_message takes the cbopaque pointer argument that is NULL unless overridden by the arguments in a call to malloc_stats_print, followed by a string pointer. Please note that doing anything which tries to allocate memory in this function is likely to result in a crash or deadlock. All messages are prefixed by “<jemalloc>: ”. RETURN VALUES Standard API The malloc and calloc functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set to ENOMEM. The posix_memalign function returns the value 0 if successful; otherwise it returns an error value. The posix_memalign function will fail if: EINVAL The alignment parameter is not a power of 2 at least as large as sizeof(void *). ENOMEM Memory allocation error. The aligned_alloc function returns a pointer to the allocated memory if successful; otherwise a NULL pointer is returned and errno is set. The aligned_alloc function will fail if: EINVAL The alignment parameter is not a power of 2. ENOMEM Memory allocation error. The realloc function returns a pointer, possibly identical to ptr, to the allocated memory if successful; otherwise a NULL pointer is returned, and errno is set to ENOMEM if the error was the result of an allocation failure. The realloc function always leaves the original buffer intact when an error occurs. The free function returns no value. Non-standard API The mallocx and rallocx functions return a pointer to the allocated memory if successful; otherwise a NULL pointer is returned to indicate insufficient contiguous memory was available to service the allocation request. The xallocx function returns the real size of the resulting resized allocation pointed to by ptr, which is a value less than size if the allocation could not be adequately grown in place. The sallocx function returns the real size of the allocation pointed to by ptr. The nallocx returns the real size that would result from a successful equivalent mallocx function call, or zero if insufficient memory is available to perform the size computation. The mallctl, mallctlnametomib, and mallctlbymib functions return 0 on success; otherwise they return an error value. The functions will fail if: EINVAL newp is not NULL, and newlen is too large or too small. Alternatively, *oldlenp is too large or too small; in this case as much data as possible are read despite the error. ENOENT name or mib specifies an unknown/invalid value. EPERM Attempt to read or write void value, or attempt to write read-only value. EAGAIN A memory allocation failure occurred. EFAULT An interface with side effects failed in some way not directly related to mallctl* read/write processing. The malloc_usable_size function returns the usable size of the allocation pointed to by ptr. ENVIRONMENT The following environment variable affects the execution of the allocation functions: MALLOC_CONF If the environment variable MALLOC_CONF is set, the characters it contains will be interpreted as options. EXAMPLES To dump core whenever a problem occurs: ln -s 'abort:true' /etc/malloc.conf To specify in the source a chunk size that is 16 MiB: SEE ALSO madvise 2, mmap 2, sbrk 2, utrace 2, alloca 3, atexit 3, getpagesize 3 STANDARDS The malloc, calloc, realloc, and free functions conform to ISO/IEC 9899:1990 (“ISO C90”).

Line editing with some support for history is a really important feature for command line utilities. Instead of retyping almost the same stuff again and again it's just much better to hit the up arrow and edit on syntax errors, or in order to try a slightly different command. But apparently code dealing with terminals is some sort of Black Magic: readline is 30k lines of code, libedit 20k. Is it reasonable to link small utilities to huge libraries just to get a minimal support for line editing? So what usually happens is either: * Large programs with configure scripts disabling line editing if readline is not present in the system, or not supporting it at all since readline is GPL licensed and libedit (the BSD clone) is not as known and available as readline is (Real world example of this problem: Tclsh). * Smaller programs not using a configure script not supporting line editing at all (A problem we had with Redis-cli for instance). The result is a pollution of binaries without line editing support. So I spent more or less two hours doing a reality check resulting in this little library: is it *really* needed for a line editing library to be 20k lines of code? Apparently not, it is possibe to get a very small, zero configuration, trivial to embed library, that solves the problem. Smaller programs will just include this, supporing line editing out of the box. Larger programs may use this little library or just checking with configure if readline/libedit is available and resorting to Linenoise if not. ## Terminals, in 2010. Apparently almost every terminal you can happen to use today has some kind of support for basic VT100 escape sequences. So I tried to write a lib using just very basic VT100 features. The resulting library appears to work everywhere I tried to use it, and now can work even on ANSI.SYS compatible terminals, since no VT220 specific sequences are used anymore. The library is currently about 1100 lines of code. In order to use it in your project just look at the *example.c* file in the source distribution, it is trivial. Linenoise is BSD code, so you can use both in free software and commercial software. ## Tested with... * Linux text only console ($TERM = linux) * Linux KDE terminal application ($TERM = xterm) * Linux xterm ($TERM = xterm) * Linux Buildroot ($TERM = vt100) * Mac OS X iTerm ($TERM = xterm) * Mac OS X default Terminal.app ($TERM = xterm) * OpenBSD 4.5 through an OSX Terminal.app ($TERM = screen) * IBM AIX 6.1 * FreeBSD xterm ($TERM = xterm) * ANSI.SYS * Emacs comint mode ($TERM = dumb) Please test it everywhere you can and report back! ## Let's push this forward! Patches should be provided in the respect of Linenoise sensibility for small easy to understand code. Send feedbacks to antirez at gmail # The API Linenoise is very easy to use, and reading the example shipped with the library should get you up to speed ASAP. Here is a list of API calls and how to use them. char *linenoise(const char *prompt); This is the main Linenoise call: it shows the user a prompt with line editing and history capabilities. The prompt you specify is used as a prompt, that is, it will be printed to the left of the cursor. The library returns a buffer with the line composed by the user, or NULL on end of file or when there is an out of memory condition. When a tty is detected (the user is actually typing into a terminal session) the maximum editable line length is `LINENOISE_MAX_LINE`. When instead the standard input is not a tty, which happens every time you redirect a file to a program, or use it in an Unix pipeline, there are no limits to the length of the line that can be returned. The returned line should be freed with the `free()` standard system call. However sometimes it could happen that your program uses a different dynamic allocation library, so you may also used `linenoiseFree` to make sure the line is freed with the same allocator it was created. The canonical loop used by a program using Linenoise will be something like this: while((line = linenoise("hello> ")) != NULL) { printf("You wrote: %s\n", line); linenoiseFree(line); /* Or just free(line) if you use libc malloc. */ } ## Single line VS multi line editing By default, Linenoise uses single line editing, that is, a single row on the screen will be used, and as the user types more, the text will scroll towards left to make room. This works if your program is one where the user is unlikely to write a lot of text, otherwise multi line editing, where multiple screens rows are used, can be a lot more comfortable. In order to enable multi line editing use the following API call: linenoiseSetMultiLine(1); You can disable it using `0` as argument. ## History Linenoise supporst history, so that the user does not have to retype again and again the same things, but can use the down and up arrows in order to search and re-edit already inserted lines of text. The followings are the history API calls: int linenoiseHistoryAdd(const char *line); int linenoiseHistorySetMaxLen(int len); int linenoiseHistorySave(const char *filename); int linenoiseHistoryLoad(const char *filename); Use `linenoiseHistoryAdd` every time you want to add a new element to the top of the history (it will be the first the user will see when using the up arrow). Note that for history to work, you have to set a length for the history (which is zero by default, so history will be disabled if you don't set a proper one). This is accomplished using the `linenoiseHistorySetMaxLen` function. Linenoise has direct support for persisting the history into an history file. The functions `linenoiseHistorySave` and `linenoiseHistoryLoad` do just that. Both functions return -1 on error and 0 on success. ## Completion Linenoise supports completion, which is the ability to complete the user input when she or he presses the `` key. In order to use completion, you need to register a completion callback, which is called every time the user presses ``. Your callback will return a list of items that are completions for the current string. The following is an example of registering a completion callback: linenoiseSetCompletionCallback(completion); The completion must be a function returning `void` and getting as input a `const char` pointer, which is the line the user has typed so far, and a `linenoiseCompletions` object pointer, which is used as argument of `linenoiseAddCompletion` in order to add completions inside the callback. An example will make it more clear: void completion(const char *buf, linenoiseCompletions *lc) { if (buf[0] == 'h') { linenoiseAddCompletion(lc,"hello"); linenoiseAddCompletion(lc,"hello there"); } } Basically in your completion callback, you inspect the input, and return a list of items that are good completions by using `linenoiseAddCompletion`. If you want to test the completion feature, compile the example program with `make`, run it, type `h` and press ``. ## Hints Linenoise has a feature called *hints* which is very useful when you use Linenoise in order to implement a REPL (Read Eval Print Loop) for a program that accepts commands and arguments, but may also be useful in other conditions. The feature shows, on the right of the cursor, as the user types, hints that may be useful. The hints can be displayed using a different color compared to the color the user is typing, and can also be bold. For example as the user starts to type `"git remote add"`, with hints it's possible to show on the right of the prompt a string ` `. The feature works similarly to the history feature, using a callback. To register the callback we use: linenoiseSetHintsCallback(hints); The callback itself is implemented like this: char *hints(const char *buf, int *color, int *bold) { if (!strcasecmp(buf,"git remote add")) { *color = 35; *bold = 0; return " "; } return NULL; } The callback function returns the string that should be displayed or NULL if no hint is available for the text the user currently typed. The returned string will be trimmed as needed depending on the number of columns available on the screen. It is possible to return a string allocated in dynamic way, by also registering a function to deallocate the hint string once used: void linenoiseSetFreeHintsCallback(linenoiseFreeHintsCallback *); The free hint callback will just receive the pointer and free the string as needed (depending on how the hits callback allocated it). As you can see in the example above, a `color` (in xterm color terminal codes) can be provided together with a `bold` attribute. If no color is set, the current terminal foreground color is used. If no bold attribute is set, non-bold text is printed. Color codes are: red = 31 green = 32 yellow = 33 blue = 34 magenta = 35 cyan = 36 white = 37; ## Screen handling Sometimes you may want to clear the screen as a result of something the user typed. You can do this by calling the following function: void linenoiseClearScreen(void); ================================================ FILE: extern/deprecated/redis-3.2.8/deps/linenoise/example.c ================================================ #include #include #include #include "linenoise.h" void completion(const char *buf, linenoiseCompletions *lc) { if (buf[0] == 'h') { linenoiseAddCompletion(lc,"hello"); linenoiseAddCompletion(lc,"hello there"); } } char *hints(const char *buf, int *color, int *bold) { if (!strcasecmp(buf,"hello")) { *color = 35; *bold = 0; return " World"; } return NULL; } int main(int argc, char **argv) { char *line; char *prgname = argv[0]; /* Parse options, with --multiline we enable multi line editing. */ while(argc > 1) { argc--; argv++; if (!strcmp(*argv,"--multiline")) { linenoiseSetMultiLine(1); printf("Multi-line mode enabled.\n"); } else if (!strcmp(*argv,"--keycodes")) { linenoisePrintKeyCodes(); exit(0); } else { fprintf(stderr, "Usage: %s [--multiline] [--keycodes]\n", prgname); exit(1); } } /* Set the completion callback.

Implementation: + new configuration scheme via luaconf.h. + incremental garbage collection. + better handling of end-of-line in the lexer. + fully reentrant parser (new Lua function `load') + better support for 64-bit machines. + native loadlib support for Mac OS X. + standard distribution in only one library (lualib.a merged into lua.a) * Changes from version 4.0 to 5.0 ------------------------------- Language: + lexical scoping. + Lua coroutines. + standard libraries now packaged in tables. + tags replaced by metatables and tag methods replaced by metamethods, stored in metatables. + proper tail calls. + each function can have its own global table, which can be shared. + new __newindex metamethod, called when we insert a new key into a table. + new block comments: --[[ ... ]]. + new generic for. + new weak tables. + new boolean type. + new syntax "local function". + (f()) returns the first value returned by f. + {f()} fills a table with all values returned by f. + \n ignored in [[\n . + fixed and-or priorities. + more general syntax for function definition (e.g. function a.x.y:f()...end). + more general syntax for function calls (e.g. (print or write)(9)). + new functions (time/date, tmpfile, unpack, require, load*, etc.). API: + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer. + introduced lightweight userdata, a simple "void*" without a metatable. + new error handling protocol: the core no longer prints error messages; all errors are reported to the caller on the stack. + new lua_atpanic for host cleanup. + new, signal-safe, hook scheme. Implementation: + new license: MIT. + new, faster, register-based virtual machine. + support for external multithreading and coroutines. + new and consistent error message format. + the core no longer needs "stdio.h" for anything (except for a single use of sprintf to convert numbers to strings). + lua.c now runs the environment variable LUA_INIT, if present. It can be "@filename", to run a file, or the chunk itself. + support for user extensions in lua.c. sample implementation given for command line editing. + new dynamic loading library, active by default on several platforms. + safe garbage-collector metamethods. + precompiled bytecodes checked for integrity (secure binary dostring). + strings are fully aligned. + position capture in string.find. + read('*l') can read lines with embedded zeros. * Changes from version 3.2 to 4.0 ------------------------------- Language: + new "break" and "for" statements (both numerical and for tables). + uniform treatment of globals: globals are now stored in a Lua table. + improved error messages. + no more '$debug': full speed *and* full debug information. + new read form: read(N) for next N bytes. + general read patterns now deprecated. (still available with -DCOMPAT_READPATTERNS.) + all return values are passed as arguments for the last function (old semantics still available with -DLUA_COMPAT_ARGRET) + garbage collection tag methods for tables now deprecated. + there is now only one tag method for order. API: + New API: fully re-entrant, simpler, and more efficient. + New debug API. Implementation: + faster than ever: cleaner virtual machine and new hashing algorithm. + non-recursive garbage-collector algorithm. + reduced memory usage for programs with many strings. + improved treatment for memory allocation errors. + improved support for 16-bit machines (we hope). + code now compiles unmodified as both ANSI C and C++. + numbers in bases other than 10 are converted using strtoul. + new -f option in Lua to support #! scripts. + luac can now combine text and binaries. * Changes from version 3.1 to 3.2 ------------------------------- + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT. + increased limit on the number of constants and globals per function (from 2^16 to 2^24). + debugging info (lua_debug and hooks) moved into lua_state and new API functions provided to get and set this info. + new debug lib gives full debugging access within Lua. + new table functions "foreachi", "sort", "tinsert", "tremove", "getn". + new io functions "flush", "seek". * Changes from version 3.0 to 3.1 ------------------------------- + NEW FEATURE: anonymous functions with closures (via "upvalues"). + new syntax: - local variables in chunks. - better scope control with DO block END. - constructors can now be also written: { record-part; list-part }. - more general syntax for function calls and lvalues, e.g.: f(x).y=1 o:f(x,y):g(z) f"string" is sugar for f("string") + strings may now contain arbitrary binary data (e.g., embedded zeros). + major code re-organization and clean-up; reduced module interdependecies. + no arbitrary limits on the total number of constants and globals. + support for multiple global contexts. + better syntax error messages. + new traversal functions "foreach" and "foreachvar". + the default for numbers is now double. changing it to use floats or longs is easy. + complete debug information stored in pre-compiled chunks. + sample interpreter now prompts user when run interactively, and also handles control-C interruptions gracefully. * Changes from version 2.5 to 3.0 ------------------------------- + NEW CONCEPT: "tag methods". Tag methods replace fallbacks as the meta-mechanism for extending the semantics of Lua. Whereas fallbacks had a global nature, tag methods work on objects having the same tag (e.g., groups of tables). Existing code that uses fallbacks should work without change. + new, general syntax for constructors {[exp] = exp, ... }. + support for handling variable number of arguments in functions (varargs). + support for conditional compilation ($if ... $else ... $end). + cleaner semantics in API simplifies host code. + better support for writing libraries (auxlib.h). + better type checking and error messages in the standard library. + luac can now also undump. * Changes from version 2.4 to 2.5 ------------------------------- + io and string libraries are now based on pattern matching; the old libraries are still available for compatibility + dofile and dostring can now return values (via return statement) + better support for 16- and 64-bit machines + expanded documentation, with more examples * Changes from version 2.2 to 2.4 ------------------------------- + external compiler creates portable binary files that can be loaded faster + interface for debugging and profiling + new "getglobal" fallback + new functions for handling references to Lua objects + new functions in standard lib + only one copy of each string is stored + expanded documentation, with more examples * Changes from version 2.1 to 2.2 ------------------------------- + functions now may be declared with any "lvalue" as a name + garbage collection of functions + support for pipes * Changes from version 1.1 to 2.1 ------------------------------- + object-oriented support + fallbacks + simplified syntax for tables + many internal improvements (end of HISTORY) ================================================ FILE: extern/deprecated/redis-3.2.8/deps/lua/INSTALL ================================================ INSTALL for Lua 5.1 * Building Lua ------------ Lua is built in the src directory, but the build process can be controlled from the top-level Makefile. Building Lua on Unix systems should be very easy. First do "make" and see if your platform is listed. If so, just do "make xxx", where xxx is your platform name. The platforms currently supported are: aix ansi bsd freebsd generic linux macosx mingw posix solaris If your platform is not listed, try the closest one or posix, generic, ansi, in this order. See below for customization instructions and for instructions on how to build with other Windows compilers. If you want to check that Lua has been built correctly, do "make test" after building Lua. Also, have a look at the example programs in test. * Installing Lua -------------- Once you have built Lua, you may want to install it in an official place in your system. In this case, do "make install". The official place and the way to install files are defined in Makefile. You must have the right permissions to install files. If you want to build and install Lua in one step, do "make xxx install", where xxx is your platform name. If you want to install Lua locally, then do "make local". This will create directories bin, include, lib, man, and install Lua there as follows: bin: lua luac include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp lib: liblua.a man/man1: lua.1 luac.1 These are the only directories you need for development. There are man pages for lua and luac, in both nroff and html, and a reference manual in html in doc, some sample code in test, and some useful stuff in etc. You don't need these directories for development. If you want to install Lua locally, but in some other directory, do "make install INSTALL_TOP=xxx", where xxx is your chosen directory. See below for instructions for Windows and other systems. * Customization ------------- Three things can be customized by editing a file: - Where and how to install Lua -- edit Makefile. - How to build Lua -- edit src/Makefile. - Lua features -- edit src/luaconf.h. You don't actually need to edit the Makefiles because you may set the relevant variables when invoking make. On the other hand, if you need to select some Lua features, you'll need to edit src/luaconf.h. The edited file will be the one installed, and it will be used by any Lua clients that you build, to ensure consistency. We strongly recommend that you enable dynamic loading. This is done automatically for all platforms listed above that have this feature (and also Windows). See src/luaconf.h and also src/Makefile. * Building Lua on Windows and other systems ----------------------------------------- If you're not using the usual Unix tools, then the instructions for building Lua depend on the compiler you use. You'll need to create projects (or whatever your compiler uses) for building the library, the interpreter, and the compiler, as follows: library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c ltm.c lundump.c lvm.c lzio.c lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c ltablib.c lstrlib.c loadlib.c linit.c interpreter: library, lua.c compiler: library, luac.c print.c If you use Visual Studio .NET, you can use etc/luavs.bat in its "Command Prompt". If all you want is to build the Lua interpreter, you may put all .c files in a single project, except for luac.c and print.c. Or just use etc/all.c. To use Lua as a library in your own programs, you'll need to know how to create and use libraries with your compiler. As mentioned above, you may edit luaconf.h to select some features before building Lua.

NAME

lua - Lua interpreter

SYNOPSIS

lua [ options ] [ script [ args ] ]

DESCRIPTION

lua is the stand-alone Lua interpreter. It loads and executes Lua programs, either in textual source form or in precompiled binary form. (Precompiled binaries are output by luac, the Lua compiler.) lua can be used as a batch interpreter and also interactively.

The given options (see below) are executed and then the Lua program in file script is loaded and executed. The given args are available to script as strings in a global table named arg. If these arguments contain spaces or other characters special to the shell, then they should be quoted (but note that the quotes will be removed by the shell). The arguments in arg start at 0, which contains the string 'script'. The index of the last argument is stored in arg.n. The arguments given in the command line before script, including the name of the interpreter, are available in negative indices in arg.

At the very start, before even handling the command line, lua executes the contents of the environment variable LUA_INIT, if it is defined. If the value of LUA_INIT is of the form '@filename', then filename is executed. Otherwise, the string is assumed to be a Lua statement and is executed.

Options start with '-' and are described below. You can use '--' to signal the end of options.

If no arguments are given, then "-v -i" is assumed when the standard input is a terminal; otherwise, "-" is assumed.

In interactive mode, lua prompts the user, reads lines from the standard input, and executes them as they are read. If a line does not contain a complete statement, then a secondary prompt is displayed and lines are read until a complete statement is formed or a syntax error is found. So, one way to interrupt the reading of an incomplete statement is to force a syntax error: adding a ';' in the middle of a statement is a sure way of forcing a syntax error (except inside multiline strings and comments; these must be closed explicitly). If a line starts with '=', then lua displays the values of all the expressions in the remainder of the line. The expressions must be separated by commas. The primary prompt is the value of the global variable _PROMPT, if this value is a string; otherwise, the default prompt is used. Similarly, the secondary prompt is the value of the global variable _PROMPT2. So, to change the prompts, set the corresponding variable to a string of your choice. You can do that after calling the interpreter or on the command line (but in this case you have to be careful with quotes if the prompt string contains a space; otherwise you may confuse the shell.) The default prompts are "> " and ">> ".

OPTIONS

- load and execute the standard input as a file, that is, not interactively, even when the standard input is a terminal.

-e stat execute statement stat. You need to quote stat if it contains spaces, quotes, or other characters special to the shell.

-i enter interactive mode after script is executed.

-l name call require('name') before executing script. Typically used to load libraries.

-v show version information.

NAME

luac - Lua compiler

SYNOPSIS

luac [ options ] [ filenames ]

DESCRIPTION

luac is the Lua compiler. It translates programs written in the Lua programming language into binary files that can be later loaded and executed.

The main advantages of precompiling chunks are: faster loading, protecting source code from accidental user changes, and off-line syntax checking.

Precompiling does not imply faster execution because in Lua chunks are always compiled into bytecodes before being executed. luac simply allows those bytecodes to be saved in a file for later execution.

Precompiled chunks are not necessarily smaller than the corresponding source. The main goal in precompiling is faster loading.

The binary files created by luac are portable only among architectures with the same word size and byte order.

luac produces a single output file containing the bytecodes for all source files given. By default, the output file is named luac.out, but you can change this with the -o option.

In the command line, you can mix text files containing Lua source and binary files containing precompiled chunks. This is useful because several precompiled chunks, even from different (but compatible) platforms, can be combined into a single precompiled chunk.

You can use '-' to indicate the standard input as a source file and '--' to signal the end of options (that is, all remaining arguments will be treated as files even if they start with '-').

The internal format of the binary files produced by luac is likely to change when a new version of Lua is released. So, save the source files of all Lua programs that you precompile.

OPTIONS

Options must be separate.

-l produce a listing of the compiled bytecode for Lua's virtual machine. Listing bytecodes is useful to learn about Lua's virtual machine. If no files are given, then luac loads luac.out and lists its contents.

-o file output to file, instead of the default luac.out. (You can use '-' for standard output, but not on platforms that open standard output in text mode.) The output file may be a source file because all files are loaded before the output file is written. Be careful not to overwrite precious files.

-p load files but do not generate any output file. Used mainly for syntax checking and for testing precompiled chunks: corrupted files will probably generate errors when loaded. Lua always performs a thorough integrity test on precompiled chunks. Bytecode that passes this test is completely safe, in the sense that it will not break the interpreter. However, there is no guarantee that such code does anything sensible. (None can be given, because the halting problem is unsolvable.) If no files are given, then luac loads luac.out and tests its contents. No messages are displayed if the file passes the integrity test.

-s strip debug information before writing the output file. This saves some space in very large chunks, but if errors occur when running a stripped chunk, then the error messages may not contain the full information they usually do. For instance, line numbers and names of local variables are lost.

-v show version information.

1 - Introduction

Lua is an extension programming language designed to support general procedural programming with data description facilities. It also offers good support for object-oriented programming, functional programming, and data-driven programming. Lua is intended to be used as a powerful, light-weight scripting language for any program that needs one. Lua is implemented as a library, written in clean C (that is, in the common subset of ANSI C and C++).

Being an extension language, Lua has no notion of a "main" program: it only works embedded in a host client, called the embedding program or simply the host. This host program can invoke functions to execute a piece of Lua code, can write and read Lua variables, and can register C functions to be called by Lua code. Through the use of C functions, Lua can be augmented to cope with a wide range of different domains, thus creating customized programming languages sharing a syntactical framework. The Lua distribution includes a sample host program called lua, which uses the Lua library to offer a complete, stand-alone Lua interpreter.

Lua is free software, and is provided as usual with no guarantees, as stated in its license. The implementation described in this manual is available at Lua's official web site, www.lua.org.

Like any other reference manual, this document is dry in places. For a discussion of the decisions behind the design of Lua, see the technical papers available at Lua's web site. For a detailed introduction to programming in Lua, see Roberto's book, Programming in Lua (Second Edition).

2 - The Language

This section describes the lexis, the syntax, and the semantics of Lua. In other words, this section describes which tokens are valid, how they can be combined, and what their combinations mean.

The language constructs will be explained using the usual extended BNF notation, in which {a} means 0 or more a's, and [a] means an optional a. Non-terminals are shown like non-terminal, keywords are shown like kword, and other terminal symbols are shown like `=´. The complete syntax of Lua can be found in §8 at the end of this manual.

2.1 - Lexical Conventions

Names (also called identifiers) in Lua can be any string of letters, digits, and underscores, not beginning with a digit. This coincides with the definition of names in most languages. (The definition of letter depends on the current locale: any character considered alphabetic by the current locale can be used in an identifier.) Identifiers are used to name variables and table fields.

The following keywords are reserved and cannot be used as names: 

     and       break     do        else      elseif
     end       false     for       function  if
     in        local     nil       not       or
     repeat    return    then      true      until     while

Lua is a case-sensitive language: and is a reserved word, but And and AND are two different, valid names. As a convention, names starting with an underscore followed by uppercase letters (such as _VERSION) are reserved for internal global variables used by Lua.

The following strings denote other tokens: 

     +     -     *     /     %     ^     #
     ==    ~=    <=    >=    <     >     =
     (     )     {     }     [     ]
     ;     :     ,     .     ..    ...

Literal strings can be delimited by matching single or double quotes, and can contain the following C-like escape sequences: '\a' (bell), '\b' (backspace), '\f' (form feed), '\n' (newline), '\r' (carriage return), '\t' (horizontal tab), '\v' (vertical tab), '\\' (backslash), '\"' (quotation mark [double quote]), and '\'' (apostrophe [single quote]). Moreover, a backslash followed by a real newline results in a newline in the string. A character in a string can also be specified by its numerical value using the escape sequence \ddd, where ddd is a sequence of up to three decimal digits. (Note that if a numerical escape is to be followed by a digit, it must be expressed using exactly three digits.) Strings in Lua can contain any 8-bit value, including embedded zeros, which can be specified as '\0'.

Literal strings can also be defined using a long format enclosed by long brackets. We define an opening long bracket of level n as an opening square bracket followed by n equal signs followed by another opening square bracket. So, an opening long bracket of level 0 is written as [[, an opening long bracket of level 1 is written as [=[, and so on. A closing long bracket is defined similarly; for instance, a closing long bracket of level 4 is written as ]====]. A long string starts with an opening long bracket of any level and ends at the first closing long bracket of the same level. Literals in this bracketed form can run for several lines, do not interpret any escape sequences, and ignore long brackets of any other level. They can contain anything except a closing bracket of the proper level.

For convenience, when the opening long bracket is immediately followed by a newline, the newline is not included in the string. As an example, in a system using ASCII (in which 'a' is coded as 97, newline is coded as 10, and '1' is coded as 49), the five literal strings below denote the same string: 

     a = 'alo\n123"'
     a = "alo\n123\""
     a = '\97lo\10\04923"'
     a = [[alo
     123"]]
     a = [==[
     alo
     123"]==]

A numerical constant can be written with an optional decimal part and an optional decimal exponent. Lua also accepts integer hexadecimal constants, by prefixing them with 0x. Examples of valid numerical constants are 

     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56

A comment starts with a double hyphen (--) anywhere outside a string. If the text immediately after -- is not an opening long bracket, the comment is a short comment, which runs until the end of the line. Otherwise, it is a long comment, which runs until the corresponding closing long bracket. Long comments are frequently used to disable code temporarily.

2.2 - Values and Types

Lua is a dynamically typed language. This means that variables do not have types; only values do. There are no type definitions in the language. All values carry their own type.

All values in Lua are first-class values. This means that all values can be stored in variables, passed as arguments to other functions, and returned as results.

There are eight basic types in Lua: nil, boolean, number, string, function, userdata, thread, and table. Nil is the type of the value nil, whose main property is to be different from any other value; it usually represents the absence of a useful value. Boolean is the type of the values false and true. Both nil and false make a condition false; any other value makes it true. Number represents real (double-precision floating-point) numbers. (It is easy to build Lua interpreters that use other internal representations for numbers, such as single-precision float or long integers; see file luaconf.h.) String represents arrays of characters. Lua is 8-bit clean: strings can contain any 8-bit character, including embedded zeros ('\0') (see §2.1).

Lua can call (and manipulate) functions written in Lua and functions written in C (see §2.5.8).

The type userdata is provided to allow arbitrary C data to be stored in Lua variables. This type corresponds to a block of raw memory and has no pre-defined operations in Lua, except assignment and identity test. However, by using metatables, the programmer can define operations for userdata values (see §2.8). Userdata values cannot be created or modified in Lua, only through the C API. This guarantees the integrity of data owned by the host program.

The type thread represents independent threads of execution and it is used to implement coroutines (see §2.11). Do not confuse Lua threads with operating-system threads. Lua supports coroutines on all systems, even those that do not support threads.

The type table implements associative arrays, that is, arrays that can be indexed not only with numbers, but with any value (except nil). Tables can be heterogeneous; that is, they can contain values of all types (except nil). Tables are the sole data structuring mechanism in Lua; they can be used to represent ordinary arrays, symbol tables, sets, records, graphs, trees, etc. To represent records, Lua uses the field name as an index. The language supports this representation by providing a.name as syntactic sugar for a["name"]. There are several convenient ways to create tables in Lua (see §2.5.7).

Like indices, the value of a table field can be of any type (except nil). In particular, because functions are first-class values, table fields can contain functions. Thus tables can also carry methods (see §2.5.9).

Tables, functions, threads, and (full) userdata values are objects: variables do not actually contain these values, only references to them. Assignment, parameter passing, and function returns always manipulate references to such values; these operations do not imply any kind of copy.

The library function type returns a string describing the type of a given value.

2.2.1 - Coercion

Lua provides automatic conversion between string and number values at run time. Any arithmetic operation applied to a string tries to convert this string to a number, following the usual conversion rules. Conversely, whenever a number is used where a string is expected, the number is converted to a string, in a reasonable format. For complete control over how numbers are converted to strings, use the format function from the string library (see string.format).

2.3 - Variables

Variables are places that store values. There are three kinds of variables in Lua: global variables, local variables, and table fields.

A single name can denote a global variable or a local variable (or a function's formal parameter, which is a particular kind of local variable): 

	var ::= Name

Name denotes identifiers, as defined in §2.1.

Any variable is assumed to be global unless explicitly declared as a local (see §2.4.7). Local variables are lexically scoped: local variables can be freely accessed by functions defined inside their scope (see §2.6).

Before the first assignment to a variable, its value is nil.

Square brackets are used to index a table: 

	var ::= prefixexp `[´ exp `]´

The meaning of accesses to global variables and table fields can be changed via metatables. An access to an indexed variable t[i] is equivalent to a call gettable_event(t,i). (See §2.8 for a complete description of the gettable_event function. This function is not defined or callable in Lua. We use it here only for explanatory purposes.)

The syntax var.Name is just syntactic sugar for var["Name"]: 

	var ::= prefixexp `.´ Name

All global variables live as fields in ordinary Lua tables, called environment tables or simply environments (see §2.9). Each function has its own reference to an environment, so that all global variables in this function will refer to this environment table. When a function is created, it inherits the environment from the function that created it. To get the environment table of a Lua function, you call getfenv. To replace it, you call setfenv. (You can only manipulate the environment of C functions through the debug library; (see §5.9).)

An access to a global variable x is equivalent to _env.x, which in turn is equivalent to 

     gettable_event(_env, "x")

where _env is the environment of the running function. (See §2.8 for a complete description of the gettable_event function. This function is not defined or callable in Lua. Similarly, the _env variable is not defined in Lua. We use them here only for explanatory purposes.)

2.4 - Statements

Lua supports an almost conventional set of statements, similar to those in Pascal or C. This set includes assignments, control structures, function calls, and variable declarations.

2.4.1 - Chunks

The unit of execution of Lua is called a chunk. A chunk is simply a sequence of statements, which are executed sequentially. Each statement can be optionally followed by a semicolon: 

	chunk ::= {stat [`;´]}

There are no empty statements and thus ';;' is not legal.

Lua handles a chunk as the body of an anonymous function with a variable number of arguments (see §2.5.9). As such, chunks can define local variables, receive arguments, and return values.

A chunk can be stored in a file or in a string inside the host program. To execute a chunk, Lua first pre-compiles the chunk into instructions for a virtual machine, and then it executes the compiled code with an interpreter for the virtual machine.

Chunks can also be pre-compiled into binary form; see program luac for details. Programs in source and compiled forms are interchangeable; Lua automatically detects the file type and acts accordingly.

2.4.2 - Blocks

A block is a list of statements; syntactically, a block is the same as a chunk: 

	block ::= chunk

A block can be explicitly delimited to produce a single statement: 

	stat ::= do block end

Explicit blocks are useful to control the scope of variable declarations. Explicit blocks are also sometimes used to add a return or break statement in the middle of another block (see §2.4.4).

2.4.3 - Assignment

Lua allows multiple assignments. Therefore, the syntax for assignment defines a list of variables on the left side and a list of expressions on the right side. The elements in both lists are separated by commas: 

	stat ::= varlist `=´ explist
	varlist ::= var {`,´ var}
	explist ::= exp {`,´ exp}

Expressions are discussed in §2.5.

Before the assignment, the list of values is adjusted to the length of the list of variables. If there are more values than needed, the excess values are thrown away. If there are fewer values than needed, the list is extended with as many nil's as needed. If the list of expressions ends with a function call, then all values returned by that call enter the list of values, before the adjustment (except when the call is enclosed in parentheses; see §2.5).

The assignment statement first evaluates all its expressions and only then are the assignments performed. Thus the code 

     i = 3
     i, a[i] = i+1, 20

sets a[3] to 20, without affecting a[4] because the i in a[i] is evaluated (to 3) before it is assigned 4. Similarly, the line 

     x, y = y, x

exchanges the values of x and y, and 

     x, y, z = y, z, x

cyclically permutes the values of x, y, and z.

The meaning of assignments to global variables and table fields can be changed via metatables. An assignment to an indexed variable t[i] = val is equivalent to settable_event(t,i,val). (See §2.8 for a complete description of the settable_event function. This function is not defined or callable in Lua. We use it here only for explanatory purposes.)

An assignment to a global variable x = val is equivalent to the assignment _env.x = val, which in turn is equivalent to 

     settable_event(_env, "x", val)

where _env is the environment of the running function. (The _env variable is not defined in Lua. We use it here only for explanatory purposes.)

2.4.4 - Control Structures

The control structures if, while, and repeat have the usual meaning and familiar syntax: 

	stat ::= while exp do block end
	stat ::= repeat block until exp
	stat ::= if exp then block {elseif exp then block} [else block] end

Lua also has a for statement, in two flavors (see §2.4.5).

The condition expression of a control structure can return any value. Both false and nil are considered false. All values different from nil and false are considered true (in particular, the number 0 and the empty string are also true).

In the repeat–until loop, the inner block does not end at the until keyword, but only after the condition. So, the condition can refer to local variables declared inside the loop block.

The return statement is used to return values from a function or a chunk (which is just a function). Functions and chunks can return more than one value, and so the syntax for the return statement is 

	stat ::= return [explist]

The break statement is used to terminate the execution of a while, repeat, or for loop, skipping to the next statement after the loop: 

	stat ::= break

A break ends the innermost enclosing loop.

The return and break statements can only be written as the last statement of a block. If it is really necessary to return or break in the middle of a block, then an explicit inner block can be used, as in the idioms do return end and do break end, because now return and break are the last statements in their (inner) blocks.

2.4.5 - For Statement

The for statement has two forms: one numeric and one generic.

The numeric for loop repeats a block of code while a control variable runs through an arithmetic progression. It has the following syntax: 

	stat ::= for Name `=´ exp `,´ exp [`,´ exp] do block end

The block is repeated for name starting at the value of the first exp, until it passes the second exp by steps of the third exp. More precisely, a for statement like 

     for v = e1, e2, e3 do block end

is equivalent to the code: 

     do
       local var, limit, step = tonumber(e1), tonumber(e2), tonumber(e3)
       if not (var and limit and step) then error() end
       while (step > 0 and var <= limit) or (step <= 0 and var >= limit) do
         local v = var
         block
         var = var + step
       end
     end

Note the following:

  • All three control expressions are evaluated only once, before the loop starts. They must all result in numbers.
  • var, limit, and step are invisible variables. The names shown here are for explanatory purposes only.
  • If the third expression (the step) is absent, then a step of 1 is used.
  • You can use break to exit a for loop.
  • The loop variable v is local to the loop; you cannot use its value after the for ends or is broken. If you need this value, assign it to another variable before breaking or exiting the loop.

The generic for statement works over functions, called iterators. On each iteration, the iterator function is called to produce a new value, stopping when this new value is nil. The generic for loop has the following syntax: 

	stat ::= for namelist in explist do block end
	namelist ::= Name {`,´ Name}

A for statement like 

     for var_1, ···, var_n in explist do block end

is equivalent to the code: 

     do
       local f, s, var = explist
       while true do
         local var_1, ···, var_n = f(s, var)
         var = var_1
         if var == nil then break end
         block
       end
     end

Note the following:

  • explist is evaluated only once. Its results are an iterator function, a state, and an initial value for the first iterator variable.
  • f, s, and var are invisible variables. The names are here for explanatory purposes only.
  • You can use break to exit a for loop.
  • The loop variables var_i are local to the loop; you cannot use their values after the for ends. If you need these values, then assign them to other variables before breaking or exiting the loop.

2.4.6 - Function Calls as Statements

To allow possible side-effects, function calls can be executed as statements: 

	stat ::= functioncall

In this case, all returned values are thrown away. Function calls are explained in §2.5.8.

2.4.7 - Local Declarations

Local variables can be declared anywhere inside a block. The declaration can include an initial assignment: 

	stat ::= local namelist [`=´ explist]

If present, an initial assignment has the same semantics of a multiple assignment (see §2.4.3). Otherwise, all variables are initialized with nil.

A chunk is also a block (see §2.4.1), and so local variables can be declared in a chunk outside any explicit block. The scope of such local variables extends until the end of the chunk.

The visibility rules for local variables are explained in §2.6.

2.5 - Expressions

The basic expressions in Lua are the following: 

	exp ::= prefixexp
	exp ::= nil | false | true
	exp ::= Number
	exp ::= String
	exp ::= function
	exp ::= tableconstructor
	exp ::= `...´
	exp ::= exp binop exp
	exp ::= unop exp
	prefixexp ::= var | functioncall | `(´ exp `)´

Numbers and literal strings are explained in §2.1; variables are explained in §2.3; function definitions are explained in §2.5.9; function calls are explained in §2.5.8; table constructors are explained in §2.5.7. Vararg expressions, denoted by three dots ('...'), can only be used when directly inside a vararg function; they are explained in §2.5.9.

Binary operators comprise arithmetic operators (see §2.5.1), relational operators (see §2.5.2), logical operators (see §2.5.3), and the concatenation operator (see §2.5.4). Unary operators comprise the unary minus (see §2.5.1), the unary not (see §2.5.3), and the unary length operator (see §2.5.5).

Both function calls and vararg expressions can result in multiple values. If an expression is used as a statement (only possible for function calls (see §2.4.6)), then its return list is adjusted to zero elements, thus discarding all returned values. If an expression is used as the last (or the only) element of a list of expressions, then no adjustment is made (unless the call is enclosed in parentheses). In all other contexts, Lua adjusts the result list to one element, discarding all values except the first one.

Here are some examples: 

     f()                -- adjusted to 0 results
     g(f(), x)          -- f() is adjusted to 1 result
     g(x, f())          -- g gets x plus all results from f()
     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
     a,b = ...          -- a gets the first vararg parameter, b gets
                        -- the second (both a and b can get nil if there
                        -- is no corresponding vararg parameter)
     
     a,b,c = x, f()     -- f() is adjusted to 2 results
     a,b,c = f()        -- f() is adjusted to 3 results
     return f()         -- returns all results from f()
     return ...         -- returns all received vararg parameters
     return x,y,f()     -- returns x, y, and all results from f()
     {f()}              -- creates a list with all results from f()
     {...}              -- creates a list with all vararg parameters
     {f(), nil}         -- f() is adjusted to 1 result

Any expression enclosed in parentheses always results in only one value. Thus, (f(x,y,z)) is always a single value, even if f returns several values. (The value of (f(x,y,z)) is the first value returned by f or nil if f does not return any values.)

2.5.1 - Arithmetic Operators

Lua supports the usual arithmetic operators: the binary + (addition), - (subtraction), * (multiplication), / (division), % (modulo), and ^ (exponentiation); and unary - (negation). If the operands are numbers, or strings that can be converted to numbers (see §2.2.1), then all operations have the usual meaning. Exponentiation works for any exponent. For instance, x^(-0.5) computes the inverse of the square root of x. Modulo is defined as 

     a % b == a - math.floor(a/b)*b

That is, it is the remainder of a division that rounds the quotient towards minus infinity.

2.5.2 - Relational Operators

The relational operators in Lua are 

     ==    ~=    <     >     <=    >=

These operators always result in false or true.

Equality (==) first compares the type of its operands. If the types are different, then the result is false. Otherwise, the values of the operands are compared. Numbers and strings are compared in the usual way. Objects (tables, userdata, threads, and functions) are compared by reference: two objects are considered equal only if they are the same object. Every time you create a new object (a table, userdata, thread, or function), this new object is different from any previously existing object.

You can change the way that Lua compares tables and userdata by using the "eq" metamethod (see §2.8).

The conversion rules of §2.2.1 do not apply to equality comparisons. Thus, "0"==0 evaluates to false, and t[0] and t["0"] denote different entries in a table.

The operator ~= is exactly the negation of equality (==).

The order operators work as follows. If both arguments are numbers, then they are compared as such. Otherwise, if both arguments are strings, then their values are compared according to the current locale. Otherwise, Lua tries to call the "lt" or the "le" metamethod (see §2.8). A comparison a > b is translated to b < a and a >= b is translated to b <= a.

2.5.3 - Logical Operators

The logical operators in Lua are and, or, and not. Like the control structures (see §2.4.4), all logical operators consider both false and nil as false and anything else as true.

The negation operator not always returns false or true. The conjunction operator and returns its first argument if this value is false or nil; otherwise, and returns its second argument. The disjunction operator or returns its first argument if this value is different from nil and false; otherwise, or returns its second argument. Both and and or use short-cut evaluation; that is, the second operand is evaluated only if necessary. Here are some examples: 

     10 or 20            --> 10
     10 or error()       --> 10
     nil or "a"          --> "a"
     nil and 10          --> nil
     false and error()   --> false
     false and nil       --> false
     false or nil        --> nil
     10 and 20           --> 20

(In this manual, --> indicates the result of the preceding expression.)

2.5.4 - Concatenation

The string concatenation operator in Lua is denoted by two dots ('..'). If both operands are strings or numbers, then they are converted to strings according to the rules mentioned in §2.2.1. Otherwise, the "concat" metamethod is called (see §2.8).

2.5.5 - The Length Operator

The length operator is denoted by the unary operator #. The length of a string is its number of bytes (that is, the usual meaning of string length when each character is one byte).

The length of a table t is defined to be any integer index n such that t[n] is not nil and t[n+1] is nil; moreover, if t[1] is nil, n can be zero. For a regular array, with non-nil values from 1 to a given n, its length is exactly that n, the index of its last value. If the array has "holes" (that is, nil values between other non-nil values), then #t can be any of the indices that directly precedes a nil value (that is, it may consider any such nil value as the end of the array).

2.5.6 - Precedence

Operator precedence in Lua follows the table below, from lower to higher priority: 

     or
     and
     <     >     <=    >=    ~=    ==
     ..
     +     -
     *     /     %
     not   #     - (unary)
     ^

As usual, you can use parentheses to change the precedences of an expression. The concatenation ('..') and exponentiation ('^') operators are right associative. All other binary operators are left associative.

2.5.7 - Table Constructors

Table constructors are expressions that create tables. Every time a constructor is evaluated, a new table is created. A constructor can be used to create an empty table or to create a table and initialize some of its fields. The general syntax for constructors is 

	tableconstructor ::= `{´ [fieldlist] `}´
	fieldlist ::= field {fieldsep field} [fieldsep]
	field ::= `[´ exp `]´ `=´ exp | Name `=´ exp | exp
	fieldsep ::= `,´ | `;´

Each field of the form [exp1] = exp2 adds to the new table an entry with key exp1 and value exp2. A field of the form name = exp is equivalent to ["name"] = exp. Finally, fields of the form exp are equivalent to [i] = exp, where i are consecutive numerical integers, starting with 1. Fields in the other formats do not affect this counting. For example, 

     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }

is equivalent to 

     do
       local t = {}
       t[f(1)] = g
       t[1] = "x"         -- 1st exp
       t[2] = "y"         -- 2nd exp
       t.x = 1            -- t["x"] = 1
       t[3] = f(x)        -- 3rd exp
       t[30] = 23
       t[4] = 45          -- 4th exp
       a = t
     end

If the last field in the list has the form exp and the expression is a function call or a vararg expression, then all values returned by this expression enter the list consecutively (see §2.5.8). To avoid this, enclose the function call or the vararg expression in parentheses (see §2.5).

The field list can have an optional trailing separator, as a convenience for machine-generated code.

2.5.8 - Function Calls

A function call in Lua has the following syntax: 

	functioncall ::= prefixexp args

In a function call, first prefixexp and args are evaluated. If the value of prefixexp has type function, then this function is called with the given arguments. Otherwise, the prefixexp "call" metamethod is called, having as first parameter the value of prefixexp, followed by the original call arguments (see §2.8).

The form 

	functioncall ::= prefixexp `:´ Name args

can be used to call "methods". A call v:name(args) is syntactic sugar for v.name(v,args), except that v is evaluated only once.

Arguments have the following syntax: 

	args ::= `(´ [explist] `)´
	args ::= tableconstructor
	args ::= String

All argument expressions are evaluated before the call. A call of the form f{fields} is syntactic sugar for f({fields}); that is, the argument list is a single new table. A call of the form f'string' (or f"string" or f[[string]]) is syntactic sugar for f('string'); that is, the argument list is a single literal string.

As an exception to the free-format syntax of Lua, you cannot put a line break before the '(' in a function call. This restriction avoids some ambiguities in the language. If you write 

     a = f
     (g).x(a)

Lua would see that as a single statement, a = f(g).x(a). So, if you want two statements, you must add a semi-colon between them. If you actually want to call f, you must remove the line break before (g).

A call of the form return functioncall is called a tail call. Lua implements proper tail calls (or proper tail recursion): in a tail call, the called function reuses the stack entry of the calling function. Therefore, there is no limit on the number of nested tail calls that a program can execute. However, a tail call erases any debug information about the calling function. Note that a tail call only happens with a particular syntax, where the return has one single function call as argument; this syntax makes the calling function return exactly the returns of the called function. So, none of the following examples are tail calls: 

     return (f(x))        -- results adjusted to 1
     return 2 * f(x)
     return x, f(x)       -- additional results
     f(x); return         -- results discarded
     return x or f(x)     -- results adjusted to 1

2.5.9 - Function Definitions

The syntax for function definition is 

	function ::= function funcbody
	funcbody ::= `(´ [parlist] `)´ block end

The following syntactic sugar simplifies function definitions: 

	stat ::= function funcname funcbody
	stat ::= local function Name funcbody
	funcname ::= Name {`.´ Name} [`:´ Name]

The statement 

     function f () body end

translates to 

     f = function () body end

The statement 

     function t.a.b.c.f () body end

translates to 

     t.a.b.c.f = function () body end

The statement 

     local function f () body end

translates to 

     local f; f = function () body end

not to 

     local f = function () body end

(This only makes a difference when the body of the function contains references to f.)

A function definition is an executable expression, whose value has type function. When Lua pre-compiles a chunk, all its function bodies are pre-compiled too. Then, whenever Lua executes the function definition, the function is instantiated (or closed). This function instance (or closure) is the final value of the expression. Different instances of the same function can refer to different external local variables and can have different environment tables.

Parameters act as local variables that are initialized with the argument values: 

	parlist ::= namelist [`,´ `...´] | `...´

When a function is called, the list of arguments is adjusted to the length of the list of parameters, unless the function is a variadic or vararg function, which is indicated by three dots ('...') at the end of its parameter list. A vararg function does not adjust its argument list; instead, it collects all extra arguments and supplies them to the function through a vararg expression, which is also written as three dots. The value of this expression is a list of all actual extra arguments, similar to a function with multiple results. If a vararg expression is used inside another expression or in the middle of a list of expressions, then its return list is adjusted to one element. If the expression is used as the last element of a list of expressions, then no adjustment is made (unless that last expression is enclosed in parentheses).

As an example, consider the following definitions: 

     function f(a, b) end
     function g(a, b, ...) end
     function r() return 1,2,3 end

Then, we have the following mapping from arguments to parameters and to the vararg expression: 

     CALL            PARAMETERS
     
     f(3)             a=3, b=nil
     f(3, 4)          a=3, b=4
     f(3, 4, 5)       a=3, b=4
     f(r(), 10)       a=1, b=10
     f(r())           a=1, b=2
     
     g(3)             a=3, b=nil, ... -->  (nothing)
     g(3, 4)          a=3, b=4,   ... -->  (nothing)
     g(3, 4, 5, 8)    a=3, b=4,   ... -->  5  8
     g(5, r())        a=5, b=1,   ... -->  2  3

Results are returned using the return statement (see §2.4.4). If control reaches the end of a function without encountering a return statement, then the function returns with no results.

The colon syntax is used for defining methods, that is, functions that have an implicit extra parameter self. Thus, the statement 

     function t.a.b.c:f (params) body end

is syntactic sugar for 

     t.a.b.c.f = function (self, params) body end

2.6 - Visibility Rules

Lua is a lexically scoped language. The scope of variables begins at the first statement after their declaration and lasts until the end of the innermost block that includes the declaration. Consider the following example: 

     x = 10                -- global variable
     do                    -- new block
       local x = x         -- new 'x', with value 10
       print(x)            --> 10
       x = x+1
       do                  -- another block
         local x = x+1     -- another 'x'
         print(x)          --> 12
       end
       print(x)            --> 11
     end
     print(x)              --> 10  (the global one)

Notice that, in a declaration like local x = x, the new x being declared is not in scope yet, and so the second x refers to the outside variable.

Because of the lexical scoping rules, local variables can be freely accessed by functions defined inside their scope. A local variable used by an inner function is called an upvalue, or external local variable, inside the inner function.

Notice that each execution of a local statement defines new local variables. Consider the following example: 

     a = {}
     local x = 20
     for i=1,10 do
       local y = 0
       a[i] = function () y=y+1; return x+y end
     end

The loop creates ten closures (that is, ten instances of the anonymous function). Each of these closures uses a different y variable, while all of them share the same x.

2.7 - Error Handling

Because Lua is an embedded extension language, all Lua actions start from C code in the host program calling a function from the Lua library (see lua_pcall). Whenever an error occurs during Lua compilation or execution, control returns to C, which can take appropriate measures (such as printing an error message).

Lua code can explicitly generate an error by calling the error function. If you need to catch errors in Lua, you can use the pcall function.

2.8 - Metatables

Every value in Lua can have a metatable. This metatable is an ordinary Lua table that defines the behavior of the original value under certain special operations. You can change several aspects of the behavior of operations over a value by setting specific fields in its metatable. For instance, when a non-numeric value is the operand of an addition, Lua checks for a function in the field "__add" in its metatable. If it finds one, Lua calls this function to perform the addition.

We call the keys in a metatable events and the values metamethods. In the previous example, the event is "add" and the metamethod is the function that performs the addition.

You can query the metatable of any value through the getmetatable function.

You can replace the metatable of tables through the setmetatable function. You cannot change the metatable of other types from Lua (except by using the debug library); you must use the C API for that.

Tables and full userdata have individual metatables (although multiple tables and userdata can share their metatables). Values of all other types share one single metatable per type; that is, there is one single metatable for all numbers, one for all strings, etc.

A metatable controls how an object behaves in arithmetic operations, order comparisons, concatenation, length operation, and indexing. A metatable also can define a function to be called when a userdata is garbage collected. For each of these operations Lua associates a specific key called an event. When Lua performs one of these operations over a value, it checks whether this value has a metatable with the corresponding event. If so, the value associated with that key (the metamethod) controls how Lua will perform the operation.

Metatables control the operations listed next. Each operation is identified by its corresponding name. The key for each operation is a string with its name prefixed by two underscores, '__'; for instance, the key for operation "add" is the string "__add". The semantics of these operations is better explained by a Lua function describing how the interpreter executes the operation.

The code shown here in Lua is only illustrative; the real behavior is hard coded in the interpreter and it is much more efficient than this simulation. All functions used in these descriptions (rawget, tonumber, etc.) are described in §5.1. In particular, to retrieve the metamethod of a given object, we use the expression 

     metatable(obj)[event]

This should be read as 

     rawget(getmetatable(obj) or {}, event)

That is, the access to a metamethod does not invoke other metamethods, and the access to objects with no metatables does not fail (it simply results in nil).

  • "add": the + operation.

    The function getbinhandler below defines how Lua chooses a handler for a binary operation. First, Lua tries the first operand. If its type does not define a handler for the operation, then Lua tries the second operand. 

         function getbinhandler (op1, op2, event)
       return metatable(op1)[event] or metatable(op2)[event]
     end

    By using this function, the behavior of the op1 + op2 is 

         function add_event (op1, op2)
       local o1, o2 = tonumber(op1), tonumber(op2)
       if o1 and o2 then  -- both operands are numeric?
         return o1 + o2   -- '+' here is the primitive 'add'
       else  -- at least one of the operands is not numeric
         local h = getbinhandler(op1, op2, "__add")
         if h then
           -- call the handler with both operands
           return (h(op1, op2))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

  • "sub": the - operation. Behavior similar to the "add" operation.
  • "mul": the * operation. Behavior similar to the "add" operation.
  • "div": the / operation. Behavior similar to the "add" operation.
  • "mod": the % operation. Behavior similar to the "add" operation, with the operation o1 - floor(o1/o2)*o2 as the primitive operation.
  • "pow": the ^ (exponentiation) operation. Behavior similar to the "add" operation, with the function pow (from the C math library) as the primitive operation.
  • "unm": the unary - operation. 
         function unm_event (op)
       local o = tonumber(op)
       if o then  -- operand is numeric?
         return -o  -- '-' here is the primitive 'unm'
       else  -- the operand is not numeric.
         -- Try to get a handler from the operand
         local h = metatable(op).__unm
         if h then
           -- call the handler with the operand
           return (h(op))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

  • "concat": the .. (concatenation) operation. 
         function concat_event (op1, op2)
       if (type(op1) == "string" or type(op1) == "number") and
          (type(op2) == "string" or type(op2) == "number") then
         return op1 .. op2  -- primitive string concatenation
       else
         local h = getbinhandler(op1, op2, "__concat")
         if h then
           return (h(op1, op2))
         else
           error(···)
         end
       end
     end

  • "len": the # operation. 
         function len_event (op)
       if type(op) == "string" then
         return strlen(op)         -- primitive string length
       elseif type(op) == "table" then
         return #op                -- primitive table length
       else
         local h = metatable(op).__len
         if h then
           -- call the handler with the operand
           return (h(op))
         else  -- no handler available: default behavior
           error(···)
         end
       end
     end

    See §2.5.5 for a description of the length of a table.

  • "eq": the == operation. The function getcomphandler defines how Lua chooses a metamethod for comparison operators. A metamethod only is selected when both objects being compared have the same type and the same metamethod for the selected operation. 
         function getcomphandler (op1, op2, event)
       if type(op1) ~= type(op2) then return nil end
       local mm1 = metatable(op1)[event]
       local mm2 = metatable(op2)[event]
       if mm1 == mm2 then return mm1 else return nil end
     end

    The "eq" event is defined as follows: 

         function eq_event (op1, op2)
       if type(op1) ~= type(op2) then  -- different types?
         return false   -- different objects
       end
       if op1 == op2 then   -- primitive equal?
         return true   -- objects are equal
       end
       -- try metamethod
       local h = getcomphandler(op1, op2, "__eq")
       if h then
         return (h(op1, op2))
       else
         return false
       end
     end

    a ~= b is equivalent to not (a == b).

  • "lt": the < operation. 
         function lt_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 < op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 < op2   -- lexicographic comparison
       else
         local h = getcomphandler(op1, op2, "__lt")
         if h then
           return (h(op1, op2))
         else
           error(···)
         end
       end
     end

    a > b is equivalent to b < a.

  • "le": the <= operation. 
         function le_event (op1, op2)
       if type(op1) == "number" and type(op2) == "number" then
         return op1 <= op2   -- numeric comparison
       elseif type(op1) == "string" and type(op2) == "string" then
         return op1 <= op2   -- lexicographic comparison
       else
         local h = getcomphandler(op1, op2, "__le")
         if h then
           return (h(op1, op2))
         else
           h = getcomphandler(op1, op2, "__lt")
           if h then
             return not h(op2, op1)
           else
             error(···)
           end
         end
       end
     end

    a >= b is equivalent to b <= a. Note that, in the absence of a "le" metamethod, Lua tries the "lt", assuming that a <= b is equivalent to not (b < a).

  • "index": The indexing access table[key]. 
         function gettable_event (table, key)
       local h
       if type(table) == "table" then
         local v = rawget(table, key)
         if v ~= nil then return v end
         h = metatable(table).__index
         if h == nil then return nil end
       else
         h = metatable(table).__index
         if h == nil then
           error(···)
         end
       end
       if type(h) == "function" then
         return (h(table, key))     -- call the handler
       else return h[key]           -- or repeat operation on it
       end
     end

  • "newindex": The indexing assignment table[key] = value. 
         function settable_event (table, key, value)
       local h
       if type(table) == "table" then
         local v = rawget(table, key)
         if v ~= nil then rawset(table, key, value); return end
         h = metatable(table).__newindex
         if h == nil then rawset(table, key, value); return end
       else
         h = metatable(table).__newindex
         if h == nil then
           error(···)
         end
       end
       if type(h) == "function" then
         h(table, key,value)           -- call the handler
       else h[key] = value             -- or repeat operation on it
       end
     end

  • "call": called when Lua calls a value. 
         function function_event (func, ...)
       if type(func) == "function" then
         return func(...)   -- primitive call
       else
         local h = metatable(func).__call
         if h then
           return h(func, ...)
         else
           error(···)
         end
       end
     end

2.9 - Environments

Besides metatables, objects of types thread, function, and userdata have another table associated with them, called their environment. Like metatables, environments are regular tables and multiple objects can share the same environment.

Threads are created sharing the environment of the creating thread. Userdata and C functions are created sharing the environment of the creating C function. Non-nested Lua functions (created by loadfile, loadstring or load) are created sharing the environment of the creating thread. Nested Lua functions are created sharing the environment of the creating Lua function.

Environments associated with userdata have no meaning for Lua. It is only a convenience feature for programmers to associate a table to a userdata.

Environments associated with threads are called global environments. They are used as the default environment for threads and non-nested Lua functions created by the thread and can be directly accessed by C code (see §3.3).

The environment associated with a C function can be directly accessed by C code (see §3.3). It is used as the default environment for other C functions and userdata created by the function.

Environments associated with Lua functions are used to resolve all accesses to global variables within the function (see §2.3). They are used as the default environment for nested Lua functions created by the function.

You can change the environment of a Lua function or the running thread by calling setfenv. You can get the environment of a Lua function or the running thread by calling getfenv. To manipulate the environment of other objects (userdata, C functions, other threads) you must use the C API.

2.10 - Garbage Collection

Lua performs automatic memory management. This means that you have to worry neither about allocating memory for new objects nor about freeing it when the objects are no longer needed. Lua manages memory automatically by running a garbage collector from time to time to collect all dead objects (that is, objects that are no longer accessible from Lua). All memory used by Lua is subject to automatic management: tables, userdata, functions, threads, strings, etc.

Lua implements an incremental mark-and-sweep collector. It uses two numbers to control its garbage-collection cycles: the garbage-collector pause and the garbage-collector step multiplier. Both use percentage points as units (so that a value of 100 means an internal value of 1).

The garbage-collector pause controls how long the collector waits before starting a new cycle. Larger values make the collector less aggressive. Values smaller than 100 mean the collector will not wait to start a new cycle. A value of 200 means that the collector waits for the total memory in use to double before starting a new cycle.

The step multiplier controls the relative speed of the collector relative to memory allocation. Larger values make the collector more aggressive but also increase the size of each incremental step. Values smaller than 100 make the collector too slow and can result in the collector never finishing a cycle. The default, 200, means that the collector runs at "twice" the speed of memory allocation.

You can change these numbers by calling lua_gc in C or collectgarbage in Lua. With these functions you can also control the collector directly (e.g., stop and restart it).

2.10.1 - Garbage-Collection Metamethods

Using the C API, you can set garbage-collector metamethods for userdata (see §2.8). These metamethods are also called finalizers. Finalizers allow you to coordinate Lua's garbage collection with external resource management (such as closing files, network or database connections, or freeing your own memory).

Garbage userdata with a field __gc in their metatables are not collected immediately by the garbage collector. Instead, Lua puts them in a list. After the collection, Lua does the equivalent of the following function for each userdata in that list: 

     function gc_event (udata)
       local h = metatable(udata).__gc
       if h then
         h(udata)
       end
     end

At the end of each garbage-collection cycle, the finalizers for userdata are called in reverse order of their creation, among those collected in that cycle. That is, the first finalizer to be called is the one associated with the userdata created last in the program. The userdata itself is freed only in the next garbage-collection cycle.

2.10.2 - Weak Tables

A weak table is a table whose elements are weak references. A weak reference is ignored by the garbage collector. In other words, if the only references to an object are weak references, then the garbage collector will collect this object.

A weak table can have weak keys, weak values, or both. A table with weak keys allows the collection of its keys, but prevents the collection of its values. A table with both weak keys and weak values allows the collection of both keys and values. In any case, if either the key or the value is collected, the whole pair is removed from the table. The weakness of a table is controlled by the __mode field of its metatable. If the __mode field is a string containing the character 'k', the keys in the table are weak. If __mode contains 'v', the values in the table are weak.

After you use a table as a metatable, you should not change the value of its __mode field. Otherwise, the weak behavior of the tables controlled by this metatable is undefined.

2.11 - Coroutines

Lua supports coroutines, also called collaborative multithreading. A coroutine in Lua represents an independent thread of execution. Unlike threads in multithread systems, however, a coroutine only suspends its execution by explicitly calling a yield function.

You create a coroutine with a call to coroutine.create. Its sole argument is a function that is the main function of the coroutine. The create function only creates a new coroutine and returns a handle to it (an object of type thread); it does not start the coroutine execution.

When you first call coroutine.resume, passing as its first argument a thread returned by coroutine.create, the coroutine starts its execution, at the first line of its main function. Extra arguments passed to coroutine.resume are passed on to the coroutine main function. After the coroutine starts running, it runs until it terminates or yields.

A coroutine can terminate its execution in two ways: normally, when its main function returns (explicitly or implicitly, after the last instruction); and abnormally, if there is an unprotected error. In the first case, coroutine.resume returns true, plus any values returned by the coroutine main function. In case of errors, coroutine.resume returns false plus an error message.

A coroutine yields by calling coroutine.yield. When a coroutine yields, the corresponding coroutine.resume returns immediately, even if the yield happens inside nested function calls (that is, not in the main function, but in a function directly or indirectly called by the main function). In the case of a yield, coroutine.resume also returns true, plus any values passed to coroutine.yield. The next time you resume the same coroutine, it continues its execution from the point where it yielded, with the call to coroutine.yield returning any extra arguments passed to coroutine.resume.

Like coroutine.create, the coroutine.wrap function also creates a coroutine, but instead of returning the coroutine itself, it returns a function that, when called, resumes the coroutine. Any arguments passed to this function go as extra arguments to coroutine.resume. coroutine.wrap returns all the values returned by coroutine.resume, except the first one (the boolean error code). Unlike coroutine.resume, coroutine.wrap does not catch errors; any error is propagated to the caller.

As an example, consider the following code: 

     function foo (a)
       print("foo", a)
       return coroutine.yield(2*a)
     end
     
     co = coroutine.create(function (a,b)
           print("co-body", a, b)
           local r = foo(a+1)
           print("co-body", r)
           local r, s = coroutine.yield(a+b, a-b)
           print("co-body", r, s)
           return b, "end"
     end)
            
     print("main", coroutine.resume(co, 1, 10))
     print("main", coroutine.resume(co, "r"))
     print("main", coroutine.resume(co, "x", "y"))
     print("main", coroutine.resume(co, "x", "y"))

When you run it, it produces the following output: 

     co-body 1       10
     foo     2
     
     main    true    4
     co-body r
     main    true    11      -9
     co-body x       y
     main    true    10      end
     main    false   cannot resume dead coroutine

3 - The Application Program Interface

This section describes the C API for Lua, that is, the set of C functions available to the host program to communicate with Lua. All API functions and related types and constants are declared in the header file lua.h.

Even when we use the term "function", any facility in the API may be provided as a macro instead. All such macros use each of their arguments exactly once (except for the first argument, which is always a Lua state), and so do not generate any hidden side-effects.

As in most C libraries, the Lua API functions do not check their arguments for validity or consistency. However, you can change this behavior by compiling Lua with a proper definition for the macro luai_apicheck, in file luaconf.h.

3.1 - The Stack

Lua uses a virtual stack to pass values to and from C. Each element in this stack represents a Lua value (nil, number, string, etc.).

Whenever Lua calls C, the called function gets a new stack, which is independent of previous stacks and of stacks of C functions that are still active. This stack initially contains any arguments to the C function and it is where the C function pushes its results to be returned to the caller (see lua_CFunction).

For convenience, most query operations in the API do not follow a strict stack discipline. Instead, they can refer to any element in the stack by using an index: A positive index represents an absolute stack position (starting at 1); a negative index represents an offset relative to the top of the stack. More specifically, if the stack has n elements, then index 1 represents the first element (that is, the element that was pushed onto the stack first) and index n represents the last element; index -1 also represents the last element (that is, the element at the top) and index -n represents the first element. We say that an index is valid if it lies between 1 and the stack top (that is, if 1 ≤ abs(index) ≤ top).

3.2 - Stack Size

When you interact with Lua API, you are responsible for ensuring consistency. In particular, you are responsible for controlling stack overflow. You can use the function lua_checkstack to grow the stack size.

Whenever Lua calls C, it ensures that at least LUA_MINSTACK stack positions are available. LUA_MINSTACK is defined as 20, so that usually you do not have to worry about stack space unless your code has loops pushing elements onto the stack.

Most query functions accept as indices any value inside the available stack space, that is, indices up to the maximum stack size you have set through lua_checkstack. Such indices are called acceptable indices. More formally, we define an acceptable index as follows: 

     (index < 0 && abs(index) <= top) ||
     (index > 0 && index <= stackspace)

Note that 0 is never an acceptable index.

3.3 - Pseudo-Indices

Unless otherwise noted, any function that accepts valid indices can also be called with pseudo-indices, which represent some Lua values that are accessible to C code but which are not in the stack. Pseudo-indices are used to access the thread environment, the function environment, the registry, and the upvalues of a C function (see §3.4).

The thread environment (where global variables live) is always at pseudo-index LUA_GLOBALSINDEX. The environment of the running C function is always at pseudo-index LUA_ENVIRONINDEX.

To access and change the value of global variables, you can use regular table operations over an environment table. For instance, to access the value of a global variable, do 

     lua_getfield(L, LUA_GLOBALSINDEX, varname);

3.4 - C Closures

When a C function is created, it is possible to associate some values with it, thus creating a C closure; these values are called upvalues and are accessible to the function whenever it is called (see lua_pushcclosure).

Whenever a C function is called, its upvalues are located at specific pseudo-indices. These pseudo-indices are produced by the macro lua_upvalueindex. The first value associated with a function is at position lua_upvalueindex(1), and so on. Any access to lua_upvalueindex(n), where n is greater than the number of upvalues of the current function (but not greater than 256), produces an acceptable (but invalid) index.

3.5 - Registry

Lua provides a registry, a pre-defined table that can be used by any C code to store whatever Lua value it needs to store. This table is always located at pseudo-index LUA_REGISTRYINDEX. Any C library can store data into this table, but it should take care to choose keys different from those used by other libraries, to avoid collisions. Typically, you should use as key a string containing your library name or a light userdata with the address of a C object in your code.

The integer keys in the registry are used by the reference mechanism, implemented by the auxiliary library, and therefore should not be used for other purposes.

3.6 - Error Handling in C

Internally, Lua uses the C longjmp facility to handle errors. (You can also choose to use exceptions if you use C++; see file luaconf.h.) When Lua faces any error (such as memory allocation errors, type errors, syntax errors, and runtime errors) it raises an error; that is, it does a long jump. A protected environment uses setjmp to set a recover point; any error jumps to the most recent active recover point.

Most functions in the API can throw an error, for instance due to a memory allocation error. The documentation for each function indicates whether it can throw errors.

Inside a C function you can throw an error by calling lua_error.

3.7 - Functions and Types

Here we list all functions and types from the C API in alphabetical order. Each function has an indicator like this: [-o, +p, x]

The first field, o, is how many elements the function pops from the stack. The second field, p, is how many elements the function pushes onto the stack. (Any function always pushes its results after popping its arguments.) A field in the form x|y means the function can push (or pop) x or y elements, depending on the situation; an interrogation mark '?' means that we cannot know how many elements the function pops/pushes by looking only at its arguments (e.g., they may depend on what is on the stack). The third field, x, tells whether the function may throw errors: '-' means the function never throws any error; 'm' means the function may throw an error only due to not enough memory; 'e' means the function may throw other kinds of errors; 'v' means the function may throw an error on purpose.

lua_Alloc

typedef void * (*lua_Alloc) (void *ud,
                             void *ptr,
                             size_t osize,
                             size_t nsize);

The type of the memory-allocation function used by Lua states. The allocator function must provide a functionality similar to realloc, but not exactly the same. Its arguments are ud, an opaque pointer passed to lua_newstate; ptr, a pointer to the block being allocated/reallocated/freed; osize, the original size of the block; nsize, the new size of the block. ptr is NULL if and only if osize is zero. When nsize is zero, the allocator must return NULL; if osize is not zero, it should free the block pointed to by ptr. When nsize is not zero, the allocator returns NULL if and only if it cannot fill the request. When nsize is not zero and osize is zero, the allocator should behave like malloc. When nsize and osize are not zero, the allocator behaves like realloc. Lua assumes that the allocator never fails when osize >= nsize.

Here is a simple implementation for the allocator function. It is used in the auxiliary library by luaL_newstate. 

     static void *l_alloc (void *ud, void *ptr, size_t osize,
                                                size_t nsize) {
       (void)ud;  (void)osize;  /* not used */
       if (nsize == 0) {
         free(ptr);
         return NULL;
       }
       else
         return realloc(ptr, nsize);
     }

This code assumes that free(NULL) has no effect and that realloc(NULL, size) is equivalent to malloc(size). ANSI C ensures both behaviors.

lua_atpanic

[-0, +0, -] 

lua_CFunction lua_atpanic (lua_State *L, lua_CFunction panicf);

Sets a new panic function and returns the old one.

If an error happens outside any protected environment, Lua calls a panic function and then calls exit(EXIT_FAILURE), thus exiting the host application. Your panic function can avoid this exit by never returning (e.g., doing a long jump).

The panic function can access the error message at the top of the stack.

lua_call

[-(nargs + 1), +nresults, e] 

void lua_call (lua_State *L, int nargs, int nresults);

Calls a function.

To call a function you must use the following protocol: first, the function to be called is pushed onto the stack; then, the arguments to the function are pushed in direct order; that is, the first argument is pushed first. Finally you call lua_call; nargs is the number of arguments that you pushed onto the stack. All arguments and the function value are popped from the stack when the function is called. The function results are pushed onto the stack when the function returns. The number of results is adjusted to nresults, unless nresults is LUA_MULTRET. In this case, all results from the function are pushed. Lua takes care that the returned values fit into the stack space. The function results are pushed onto the stack in direct order (the first result is pushed first), so that after the call the last result is on the top of the stack.

Any error inside the called function is propagated upwards (with a longjmp).

The following example shows how the host program can do the equivalent to this Lua code: 

     a = f("how", t.x, 14)

Here it is in C: 

     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
     lua_pushstring(L, "how");                        /* 1st argument */
     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
     lua_remove(L, -2);                  /* remove 't' from the stack */
     lua_pushinteger(L, 14);                          /* 3rd argument */
     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */

Note that the code above is "balanced": at its end, the stack is back to its original configuration. This is considered good programming practice.

lua_CFunction

typedef int (*lua_CFunction) (lua_State *L);

Type for C functions.

In order to communicate properly with Lua, a C function must use the following protocol, which defines the way parameters and results are passed: a C function receives its arguments from Lua in its stack in direct order (the first argument is pushed first). So, when the function starts, lua_gettop(L) returns the number of arguments received by the function. The first argument (if any) is at index 1 and its last argument is at index lua_gettop(L). To return values to Lua, a C function just pushes them onto the stack, in direct order (the first result is pushed first), and returns the number of results. Any other value in the stack below the results will be properly discarded by Lua. Like a Lua function, a C function called by Lua can also return many results.

As an example, the following function receives a variable number of numerical arguments and returns their average and sum: 

     static int foo (lua_State *L) {
       int n = lua_gettop(L);    /* number of arguments */
       lua_Number sum = 0;
       int i;
       for (i = 1; i <= n; i++) {
         if (!lua_isnumber(L, i)) {
           lua_pushstring(L, "incorrect argument");
           lua_error(L);
         }
         sum += lua_tonumber(L, i);
       }
       lua_pushnumber(L, sum/n);        /* first result */
       lua_pushnumber(L, sum);         /* second result */
       return 2;                   /* number of results */
     }

lua_checkstack

[-0, +0, m] 

int lua_checkstack (lua_State *L, int extra);

Ensures that there are at least extra free stack slots in the stack. It returns false if it cannot grow the stack to that size. This function never shrinks the stack; if the stack is already larger than the new size, it is left unchanged.

lua_close

[-0, +0, -] 

void lua_close (lua_State *L);

Destroys all objects in the given Lua state (calling the corresponding garbage-collection metamethods, if any) and frees all dynamic memory used by this state. On several platforms, you may not need to call this function, because all resources are naturally released when the host program ends. On the other hand, long-running programs, such as a daemon or a web server, might need to release states as soon as they are not needed, to avoid growing too large.

lua_concat

[-n, +1, e] 

void lua_concat (lua_State *L, int n);

Concatenates the n values at the top of the stack, pops them, and leaves the result at the top. If n is 1, the result is the single value on the stack (that is, the function does nothing); if n is 0, the result is the empty string. Concatenation is performed following the usual semantics of Lua (see §2.5.4).

lua_cpcall

[-0, +(0|1), -] 

int lua_cpcall (lua_State *L, lua_CFunction func, void *ud);

Calls the C function func in protected mode. func starts with only one element in its stack, a light userdata containing ud. In case of errors, lua_cpcall returns the same error codes as lua_pcall, plus the error object on the top of the stack; otherwise, it returns zero, and does not change the stack. All values returned by func are discarded.

lua_createtable

[-0, +1, m] 

void lua_createtable (lua_State *L, int narr, int nrec);

Creates a new empty table and pushes it onto the stack. The new table has space pre-allocated for narr array elements and nrec non-array elements. This pre-allocation is useful when you know exactly how many elements the table will have. Otherwise you can use the function lua_newtable.

lua_dump

[-0, +0, m] 

int lua_dump (lua_State *L, lua_Writer writer, void *data);

Dumps a function as a binary chunk. Receives a Lua function on the top of the stack and produces a binary chunk that, if loaded again, results in a function equivalent to the one dumped. As it produces parts of the chunk, lua_dump calls function writer (see lua_Writer) with the given data to write them.

The value returned is the error code returned by the last call to the writer; 0 means no errors.

This function does not pop the Lua function from the stack.

lua_equal

[-0, +0, e] 

int lua_equal (lua_State *L, int index1, int index2);

Returns 1 if the two values in acceptable indices index1 and index2 are equal, following the semantics of the Lua == operator (that is, may call metamethods). Otherwise returns 0. Also returns 0 if any of the indices is non valid.

lua_error

[-1, +0, v] 

int lua_error (lua_State *L);

Generates a Lua error. The error message (which can actually be a Lua value of any type) must be on the stack top. This function does a long jump, and therefore never returns. (see luaL_error).

lua_gc

[-0, +0, e] 

int lua_gc (lua_State *L, int what, int data);

Controls the garbage collector.

This function performs several tasks, according to the value of the parameter what:

  • LUA_GCSTOP: stops the garbage collector.
  • LUA_GCRESTART: restarts the garbage collector.
  • LUA_GCCOLLECT: performs a full garbage-collection cycle.
  • LUA_GCCOUNT: returns the current amount of memory (in Kbytes) in use by Lua.
  • LUA_GCCOUNTB: returns the remainder of dividing the current amount of bytes of memory in use by Lua by 1024.
  • LUA_GCSTEP: performs an incremental step of garbage collection. The step "size" is controlled by data (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of data. The function returns 1 if the step finished a garbage-collection cycle.
  • LUA_GCSETPAUSE: sets data as the new value for the pause of the collector (see §2.10). The function returns the previous value of the pause.
  • LUA_GCSETSTEPMUL: sets data as the new value for the step multiplier of the collector (see §2.10). The function returns the previous value of the step multiplier.

lua_getallocf

[-0, +0, -] 

lua_Alloc lua_getallocf (lua_State *L, void **ud);

Returns the memory-allocation function of a given state. If ud is not NULL, Lua stores in *ud the opaque pointer passed to lua_newstate.

lua_getfenv

[-0, +1, -] 

void lua_getfenv (lua_State *L, int index);

Pushes onto the stack the environment table of the value at the given index.

lua_getfield

[-0, +1, e] 

void lua_getfield (lua_State *L, int index, const char *k);

Pushes onto the stack the value t[k], where t is the value at the given valid index. As in Lua, this function may trigger a metamethod for the "index" event (see §2.8).

lua_getglobal

[-0, +1, e] 

void lua_getglobal (lua_State *L, const char *name);

Pushes onto the stack the value of the global name. It is defined as a macro: 

     #define lua_getglobal(L,s)  lua_getfield(L, LUA_GLOBALSINDEX, s)

lua_getmetatable

[-0, +(0|1), -] 

int lua_getmetatable (lua_State *L, int index);

Pushes onto the stack the metatable of the value at the given acceptable index. If the index is not valid, or if the value does not have a metatable, the function returns 0 and pushes nothing on the stack.

lua_gettable

[-1, +1, e] 

void lua_gettable (lua_State *L, int index);

Pushes onto the stack the value t[k], where t is the value at the given valid index and k is the value at the top of the stack.

This function pops the key from the stack (putting the resulting value in its place). As in Lua, this function may trigger a metamethod for the "index" event (see §2.8).

lua_gettop

[-0, +0, -] 

int lua_gettop (lua_State *L);

Returns the index of the top element in the stack. Because indices start at 1, this result is equal to the number of elements in the stack (and so 0 means an empty stack).

lua_insert

[-1, +1, -] 

void lua_insert (lua_State *L, int index);

Moves the top element into the given valid index, shifting up the elements above this index to open space. Cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.

lua_Integer

typedef ptrdiff_t lua_Integer;

The type used by the Lua API to represent integral values.

By default it is a ptrdiff_t, which is usually the largest signed integral type the machine handles "comfortably".

lua_isboolean

[-0, +0, -] 

int lua_isboolean (lua_State *L, int index);

Returns 1 if the value at the given acceptable index has type boolean, and 0 otherwise.

lua_iscfunction

[-0, +0, -] 

int lua_iscfunction (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a C function, and 0 otherwise.

lua_isfunction

[-0, +0, -] 

int lua_isfunction (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a function (either C or Lua), and 0 otherwise.

lua_islightuserdata

[-0, +0, -] 

int lua_islightuserdata (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a light userdata, and 0 otherwise.

lua_isnil

[-0, +0, -] 

int lua_isnil (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is nil, and 0 otherwise.

lua_isnone

[-0, +0, -] 

int lua_isnone (lua_State *L, int index);

Returns 1 if the given acceptable index is not valid (that is, it refers to an element outside the current stack), and 0 otherwise.

lua_isnoneornil

[-0, +0, -] 

int lua_isnoneornil (lua_State *L, int index);

Returns 1 if the given acceptable index is not valid (that is, it refers to an element outside the current stack) or if the value at this index is nil, and 0 otherwise.

lua_isnumber

[-0, +0, -] 

int lua_isnumber (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a number or a string convertible to a number, and 0 otherwise.

lua_isstring

[-0, +0, -] 

int lua_isstring (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a string or a number (which is always convertible to a string), and 0 otherwise.

lua_istable

[-0, +0, -] 

int lua_istable (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a table, and 0 otherwise.

lua_isthread

[-0, +0, -] 

int lua_isthread (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a thread, and 0 otherwise.

lua_isuserdata

[-0, +0, -] 

int lua_isuserdata (lua_State *L, int index);

Returns 1 if the value at the given acceptable index is a userdata (either full or light), and 0 otherwise.

lua_lessthan

[-0, +0, e] 

int lua_lessthan (lua_State *L, int index1, int index2);

Returns 1 if the value at acceptable index index1 is smaller than the value at acceptable index index2, following the semantics of the Lua < operator (that is, may call metamethods). Otherwise returns 0. Also returns 0 if any of the indices is non valid.

lua_load

[-0, +1, -] 

int lua_load (lua_State *L,
              lua_Reader reader,
              void *data,
              const char *chunkname);

Loads a Lua chunk. If there are no errors, lua_load pushes the compiled chunk as a Lua function on top of the stack. Otherwise, it pushes an error message. The return values of lua_load are:

This function only loads a chunk; it does not run it.

lua_load automatically detects whether the chunk is text or binary, and loads it accordingly (see program luac).

The lua_load function uses a user-supplied reader function to read the chunk (see lua_Reader). The data argument is an opaque value passed to the reader function.

The chunkname argument gives a name to the chunk, which is used for error messages and in debug information (see §3.8).

lua_newstate

[-0, +0, -] 

lua_State *lua_newstate (lua_Alloc f, void *ud);

Creates a new, independent state. Returns NULL if cannot create the state (due to lack of memory). The argument f is the allocator function; Lua does all memory allocation for this state through this function. The second argument, ud, is an opaque pointer that Lua simply passes to the allocator in every call.

lua_newtable

[-0, +1, m] 

void lua_newtable (lua_State *L);

Creates a new empty table and pushes it onto the stack. It is equivalent to lua_createtable(L, 0, 0).

lua_newthread

[-0, +1, m] 

lua_State *lua_newthread (lua_State *L);

Creates a new thread, pushes it on the stack, and returns a pointer to a lua_State that represents this new thread. The new state returned by this function shares with the original state all global objects (such as tables), but has an independent execution stack.

There is no explicit function to close or to destroy a thread. Threads are subject to garbage collection, like any Lua object.

lua_newuserdata

[-0, +1, m] 

void *lua_newuserdata (lua_State *L, size_t size);

This function allocates a new block of memory with the given size, pushes onto the stack a new full userdata with the block address, and returns this address.

Userdata represent C values in Lua. A full userdata represents a block of memory. It is an object (like a table): you must create it, it can have its own metatable, and you can detect when it is being collected. A full userdata is only equal to itself (under raw equality).

When Lua collects a full userdata with a gc metamethod, Lua calls the metamethod and marks the userdata as finalized. When this userdata is collected again then Lua frees its corresponding memory.

lua_next

[-1, +(2|0), e] 

int lua_next (lua_State *L, int index);

Pops a key from the stack, and pushes a key-value pair from the table at the given index (the "next" pair after the given key). If there are no more elements in the table, then lua_next returns 0 (and pushes nothing).

A typical traversal looks like this: 

     /* table is in the stack at index 't' */
     lua_pushnil(L);  /* first key */
     while (lua_next(L, t) != 0) {
       /* uses 'key' (at index -2) and 'value' (at index -1) */
       printf("%s - %s\n",
              lua_typename(L, lua_type(L, -2)),
              lua_typename(L, lua_type(L, -1)));
       /* removes 'value'; keeps 'key' for next iteration */
       lua_pop(L, 1);
     }

While traversing a table, do not call lua_tolstring directly on a key, unless you know that the key is actually a string. Recall that lua_tolstring changes the value at the given index; this confuses the next call to lua_next.

lua_Number

typedef double lua_Number;

The type of numbers in Lua. By default, it is double, but that can be changed in luaconf.h.

Through the configuration file you can change Lua to operate with another type for numbers (e.g., float or long).

lua_objlen

[-0, +0, -] 

size_t lua_objlen (lua_State *L, int index);

Returns the "length" of the value at the given acceptable index: for strings, this is the string length; for tables, this is the result of the length operator ('#'); for userdata, this is the size of the block of memory allocated for the userdata; for other values, it is 0.

lua_pcall

[-(nargs + 1), +(nresults|1), -] 

int lua_pcall (lua_State *L, int nargs, int nresults, int errfunc);

Calls a function in protected mode.

Both nargs and nresults have the same meaning as in lua_call. If there are no errors during the call, lua_pcall behaves exactly like lua_call. However, if there is any error, lua_pcall catches it, pushes a single value on the stack (the error message), and returns an error code. Like lua_call, lua_pcall always removes the function and its arguments from the stack.

If errfunc is 0, then the error message returned on the stack is exactly the original error message. Otherwise, errfunc is the stack index of an error handler function. (In the current implementation, this index cannot be a pseudo-index.) In case of runtime errors, this function will be called with the error message and its return value will be the message returned on the stack by lua_pcall.

Typically, the error handler function is used to add more debug information to the error message, such as a stack traceback. Such information cannot be gathered after the return of lua_pcall, since by then the stack has unwound.

The lua_pcall function returns 0 in case of success or one of the following error codes (defined in lua.h):

  • LUA_ERRRUN: a runtime error.
  • LUA_ERRMEM: memory allocation error. For such errors, Lua does not call the error handler function.
  • LUA_ERRERR: error while running the error handler function.

lua_pop

[-n, +0, -] 

void lua_pop (lua_State *L, int n);

Pops n elements from the stack.

lua_pushboolean

[-0, +1, -] 

void lua_pushboolean (lua_State *L, int b);

Pushes a boolean value with value b onto the stack.

lua_pushcclosure

[-n, +1, m] 

void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);

Pushes a new C closure onto the stack.

When a C function is created, it is possible to associate some values with it, thus creating a C closure (see §3.4); these values are then accessible to the function whenever it is called. To associate values with a C function, first these values should be pushed onto the stack (when there are multiple values, the first value is pushed first). Then lua_pushcclosure is called to create and push the C function onto the stack, with the argument n telling how many values should be associated with the function. lua_pushcclosure also pops these values from the stack.

The maximum value for n is 255.

lua_pushcfunction

[-0, +1, m] 

void lua_pushcfunction (lua_State *L, lua_CFunction f);

Pushes a C function onto the stack. This function receives a pointer to a C function and pushes onto the stack a Lua value of type function that, when called, invokes the corresponding C function.

Any function to be registered in Lua must follow the correct protocol to receive its parameters and return its results (see lua_CFunction).

lua_pushcfunction is defined as a macro: 

     #define lua_pushcfunction(L,f)  lua_pushcclosure(L,f,0)

lua_pushfstring

[-0, +1, m] 

const char *lua_pushfstring (lua_State *L, const char *fmt, ...);

Pushes onto the stack a formatted string and returns a pointer to this string. It is similar to the C function sprintf, but has some important differences:

  • You do not have to allocate space for the result: the result is a Lua string and Lua takes care of memory allocation (and deallocation, through garbage collection).
  • The conversion specifiers are quite restricted. There are no flags, widths, or precisions. The conversion specifiers can only be '%%' (inserts a '%' in the string), '%s' (inserts a zero-terminated string, with no size restrictions), '%f' (inserts a lua_Number), '%p' (inserts a pointer as a hexadecimal numeral), '%d' (inserts an int), and '%c' (inserts an int as a character).

lua_pushinteger

[-0, +1, -] 

void lua_pushinteger (lua_State *L, lua_Integer n);

Pushes a number with value n onto the stack.

lua_pushlightuserdata

[-0, +1, -] 

void lua_pushlightuserdata (lua_State *L, void *p);

Pushes a light userdata onto the stack.

Userdata represent C values in Lua. A light userdata represents a pointer. It is a value (like a number): you do not create it, it has no individual metatable, and it is not collected (as it was never created). A light userdata is equal to "any" light userdata with the same C address.

lua_pushliteral

[-0, +1, m] 

void lua_pushliteral (lua_State *L, const char *s);

This macro is equivalent to lua_pushlstring, but can be used only when s is a literal string. In these cases, it automatically provides the string length.

lua_pushlstring

[-0, +1, m] 

void lua_pushlstring (lua_State *L, const char *s, size_t len);

Pushes the string pointed to by s with size len onto the stack. Lua makes (or reuses) an internal copy of the given string, so the memory at s can be freed or reused immediately after the function returns. The string can contain embedded zeros.

lua_pushnil

[-0, +1, -] 

void lua_pushnil (lua_State *L);

Pushes a nil value onto the stack.

lua_pushnumber

[-0, +1, -] 

void lua_pushnumber (lua_State *L, lua_Number n);

Pushes a number with value n onto the stack.

lua_pushstring

[-0, +1, m] 

void lua_pushstring (lua_State *L, const char *s);

Pushes the zero-terminated string pointed to by s onto the stack. Lua makes (or reuses) an internal copy of the given string, so the memory at s can be freed or reused immediately after the function returns. The string cannot contain embedded zeros; it is assumed to end at the first zero.

lua_pushthread

[-0, +1, -] 

int lua_pushthread (lua_State *L);

Pushes the thread represented by L onto the stack. Returns 1 if this thread is the main thread of its state.

lua_pushvalue

[-0, +1, -] 

void lua_pushvalue (lua_State *L, int index);

Pushes a copy of the element at the given valid index onto the stack.

lua_pushvfstring

[-0, +1, m] 

const char *lua_pushvfstring (lua_State *L,
                              const char *fmt,
                              va_list argp);

Equivalent to lua_pushfstring, except that it receives a va_list instead of a variable number of arguments.

lua_rawequal

[-0, +0, -] 

int lua_rawequal (lua_State *L, int index1, int index2);

Returns 1 if the two values in acceptable indices index1 and index2 are primitively equal (that is, without calling metamethods). Otherwise returns 0. Also returns 0 if any of the indices are non valid.

lua_rawget

[-1, +1, -] 

void lua_rawget (lua_State *L, int index);

Similar to lua_gettable, but does a raw access (i.e., without metamethods).

lua_rawgeti

[-0, +1, -] 

void lua_rawgeti (lua_State *L, int index, int n);

Pushes onto the stack the value t[n], where t is the value at the given valid index. The access is raw; that is, it does not invoke metamethods.

lua_rawset

[-2, +0, m] 

void lua_rawset (lua_State *L, int index);

Similar to lua_settable, but does a raw assignment (i.e., without metamethods).

lua_rawseti

[-1, +0, m] 

void lua_rawseti (lua_State *L, int index, int n);

Does the equivalent of t[n] = v, where t is the value at the given valid index and v is the value at the top of the stack.

This function pops the value from the stack. The assignment is raw; that is, it does not invoke metamethods.

lua_Reader

typedef const char * (*lua_Reader) (lua_State *L,
                                    void *data,
                                    size_t *size);

The reader function used by lua_load. Every time it needs another piece of the chunk, lua_load calls the reader, passing along its data parameter. The reader must return a pointer to a block of memory with a new piece of the chunk and set size to the block size. The block must exist until the reader function is called again. To signal the end of the chunk, the reader must return NULL or set size to zero. The reader function may return pieces of any size greater than zero.

lua_register

[-0, +0, e] 

void lua_register (lua_State *L,
                   const char *name,
                   lua_CFunction f);

Sets the C function f as the new value of global name. It is defined as a macro: 

     #define lua_register(L,n,f) \
            (lua_pushcfunction(L, f), lua_setglobal(L, n))

lua_remove

[-1, +0, -] 

void lua_remove (lua_State *L, int index);

Removes the element at the given valid index, shifting down the elements above this index to fill the gap. Cannot be called with a pseudo-index, because a pseudo-index is not an actual stack position.

lua_replace

[-1, +0, -] 

void lua_replace (lua_State *L, int index);

Moves the top element into the given position (and pops it), without shifting any element (therefore replacing the value at the given position).

lua_resume

[-?, +?, -] 

int lua_resume (lua_State *L, int narg);

Starts and resumes a coroutine in a given thread.

To start a coroutine, you first create a new thread (see lua_newthread); then you push onto its stack the main function plus any arguments; then you call lua_resume, with narg being the number of arguments. This call returns when the coroutine suspends or finishes its execution. When it returns, the stack contains all values passed to lua_yield, or all values returned by the body function. lua_resume returns LUA_YIELD if the coroutine yields, 0 if the coroutine finishes its execution without errors, or an error code in case of errors (see lua_pcall). In case of errors, the stack is not unwound, so you can use the debug API over it. The error message is on the top of the stack. To restart a coroutine, you put on its stack only the values to be passed as results from yield, and then call lua_resume.

lua_setallocf

[-0, +0, -] 

void lua_setallocf (lua_State *L, lua_Alloc f, void *ud);

Changes the allocator function of a given state to f with user data ud.

lua_setfenv

[-1, +0, -] 

int lua_setfenv (lua_State *L, int index);

Pops a table from the stack and sets it as the new environment for the value at the given index. If the value at the given index is neither a function nor a thread nor a userdata, lua_setfenv returns 0. Otherwise it returns 1.

lua_setfield

[-1, +0, e] 

void lua_setfield (lua_State *L, int index, const char *k);

Does the equivalent to t[k] = v, where t is the value at the given valid index and v is the value at the top of the stack.

This function pops the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event (see §2.8).

lua_setglobal

[-1, +0, e] 

void lua_setglobal (lua_State *L, const char *name);

Pops a value from the stack and sets it as the new value of global name. It is defined as a macro: 

     #define lua_setglobal(L,s)   lua_setfield(L, LUA_GLOBALSINDEX, s)

lua_setmetatable

[-1, +0, -] 

int lua_setmetatable (lua_State *L, int index);

Pops a table from the stack and sets it as the new metatable for the value at the given acceptable index.

lua_settable

[-2, +0, e] 

void lua_settable (lua_State *L, int index);

Does the equivalent to t[k] = v, where t is the value at the given valid index, v is the value at the top of the stack, and k is the value just below the top.

This function pops both the key and the value from the stack. As in Lua, this function may trigger a metamethod for the "newindex" event (see §2.8).

lua_settop

[-?, +?, -] 

void lua_settop (lua_State *L, int index);

Accepts any acceptable index, or 0, and sets the stack top to this index. If the new top is larger than the old one, then the new elements are filled with nil. If index is 0, then all stack elements are removed.

lua_State

typedef struct lua_State lua_State;

Opaque structure that keeps the whole state of a Lua interpreter. The Lua library is fully reentrant: it has no global variables. All information about a state is kept in this structure.

A pointer to this state must be passed as the first argument to every function in the library, except to lua_newstate, which creates a Lua state from scratch.

lua_status

[-0, +0, -] 

int lua_status (lua_State *L);

Returns the status of the thread L.

The status can be 0 for a normal thread, an error code if the thread finished its execution with an error, or LUA_YIELD if the thread is suspended.

lua_toboolean

[-0, +0, -] 

int lua_toboolean (lua_State *L, int index);

Converts the Lua value at the given acceptable index to a C boolean value (0 or 1). Like all tests in Lua, lua_toboolean returns 1 for any Lua value different from false and nil; otherwise it returns 0. It also returns 0 when called with a non-valid index. (If you want to accept only actual boolean values, use lua_isboolean to test the value's type.)

lua_tocfunction

[-0, +0, -] 

lua_CFunction lua_tocfunction (lua_State *L, int index);

Converts a value at the given acceptable index to a C function. That value must be a C function; otherwise, returns NULL.

lua_tointeger

[-0, +0, -] 

lua_Integer lua_tointeger (lua_State *L, int index);

Converts the Lua value at the given acceptable index to the signed integral type lua_Integer. The Lua value must be a number or a string convertible to a number (see §2.2.1); otherwise, lua_tointeger returns 0.

If the number is not an integer, it is truncated in some non-specified way.

lua_tolstring

[-0, +0, m] 

const char *lua_tolstring (lua_State *L, int index, size_t *len);

Converts the Lua value at the given acceptable index to a C string. If len is not NULL, it also sets *len with the string length. The Lua value must be a string or a number; otherwise, the function returns NULL. If the value is a number, then lua_tolstring also changes the actual value in the stack to a string. (This change confuses lua_next when lua_tolstring is applied to keys during a table traversal.)

lua_tolstring returns a fully aligned pointer to a string inside the Lua state. This string always has a zero ('\0') after its last character (as in C), but can contain other zeros in its body. Because Lua has garbage collection, there is no guarantee that the pointer returned by lua_tolstring will be valid after the corresponding value is removed from the stack.

lua_tonumber

[-0, +0, -] 

lua_Number lua_tonumber (lua_State *L, int index);

Converts the Lua value at the given acceptable index to the C type lua_Number (see lua_Number). The Lua value must be a number or a string convertible to a number (see §2.2.1); otherwise, lua_tonumber returns 0.

lua_topointer

[-0, +0, -] 

const void *lua_topointer (lua_State *L, int index);

Converts the value at the given acceptable index to a generic C pointer (void*). The value can be a userdata, a table, a thread, or a function; otherwise, lua_topointer returns NULL. Different objects will give different pointers. There is no way to convert the pointer back to its original value.

Typically this function is used only for debug information.

lua_tostring

[-0, +0, m] 

const char *lua_tostring (lua_State *L, int index);

Equivalent to lua_tolstring with len equal to NULL.

lua_tothread

[-0, +0, -] 

lua_State *lua_tothread (lua_State *L, int index);

Converts the value at the given acceptable index to a Lua thread (represented as lua_State*). This value must be a thread; otherwise, the function returns NULL.

lua_touserdata

[-0, +0, -] 

void *lua_touserdata (lua_State *L, int index);

If the value at the given acceptable index is a full userdata, returns its block address. If the value is a light userdata, returns its pointer. Otherwise, returns NULL.

lua_type

[-0, +0, -] 

int lua_type (lua_State *L, int index);

Returns the type of the value in the given acceptable index, or LUA_TNONE for a non-valid index (that is, an index to an "empty" stack position). The types returned by lua_type are coded by the following constants defined in lua.h: LUA_TNIL, LUA_TNUMBER, LUA_TBOOLEAN, LUA_TSTRING, LUA_TTABLE, LUA_TFUNCTION, LUA_TUSERDATA, LUA_TTHREAD, and LUA_TLIGHTUSERDATA.

lua_typename

[-0, +0, -] 

const char *lua_typename  (lua_State *L, int tp);

Returns the name of the type encoded by the value tp, which must be one the values returned by lua_type.

lua_Writer

typedef int (*lua_Writer) (lua_State *L,
                           const void* p,
                           size_t sz,
                           void* ud);

The type of the writer function used by lua_dump. Every time it produces another piece of chunk, lua_dump calls the writer, passing along the buffer to be written (p), its size (sz), and the data parameter supplied to lua_dump.

The writer returns an error code: 0 means no errors; any other value means an error and stops lua_dump from calling the writer again.

lua_xmove

[-?, +?, -] 

void lua_xmove (lua_State *from, lua_State *to, int n);

Exchange values between different threads of the same global state.

This function pops n values from the stack from, and pushes them onto the stack to.

lua_yield

[-?, +?, -] 

int lua_yield  (lua_State *L, int nresults);

Yields a coroutine.

This function should only be called as the return expression of a C function, as follows: 

     return lua_yield (L, nresults);

When a C function calls lua_yield in that way, the running coroutine suspends its execution, and the call to lua_resume that started this coroutine returns. The parameter nresults is the number of values from the stack that are passed as results to lua_resume.

3.8 - The Debug Interface

Lua has no built-in debugging facilities. Instead, it offers a special interface by means of functions and hooks. This interface allows the construction of different kinds of debuggers, profilers, and other tools that need "inside information" from the interpreter.

lua_Debug

typedef struct lua_Debug {
  int event;
  const char *name;           /* (n) */
  const char *namewhat;       /* (n) */
  const char *what;           /* (S) */
  const char *source;         /* (S) */
  int currentline;            /* (l) */
  int nups;                   /* (u) number of upvalues */
  int linedefined;            /* (S) */
  int lastlinedefined;        /* (S) */
  char short_src[LUA_IDSIZE]; /* (S) */
  /* private part */
  other fields
} lua_Debug;

A structure used to carry different pieces of information about an active function. lua_getstack fills only the private part of this structure, for later use. To fill the other fields of lua_Debug with useful information, call lua_getinfo.

The fields of lua_Debug have the following meaning:

  • source: If the function was defined in a string, then source is that string. If the function was defined in a file, then source starts with a '@' followed by the file name.
  • short_src: a "printable" version of source, to be used in error messages.
  • linedefined: the line number where the definition of the function starts.
  • lastlinedefined: the line number where the definition of the function ends.
  • what: the string "Lua" if the function is a Lua function, "C" if it is a C function, "main" if it is the main part of a chunk, and "tail" if it was a function that did a tail call. In the latter case, Lua has no other information about the function.
  • currentline: the current line where the given function is executing. When no line information is available, currentline is set to -1.
  • name: a reasonable name for the given function. Because functions in Lua are first-class values, they do not have a fixed name: some functions can be the value of multiple global variables, while others can be stored only in a table field. The lua_getinfo function checks how the function was called to find a suitable name. If it cannot find a name, then name is set to NULL.
  • namewhat: explains the name field. The value of namewhat can be "global", "local", "method", "field", "upvalue", or "" (the empty string), according to how the function was called. (Lua uses the empty string when no other option seems to apply.)
  • nups: the number of upvalues of the function.

lua_gethook

[-0, +0, -] 

lua_Hook lua_gethook (lua_State *L);

Returns the current hook function.

lua_gethookcount

[-0, +0, -] 

int lua_gethookcount (lua_State *L);

Returns the current hook count.

lua_gethookmask

[-0, +0, -] 

int lua_gethookmask (lua_State *L);

Returns the current hook mask.

lua_getinfo

[-(0|1), +(0|1|2), m] 

int lua_getinfo (lua_State *L, const char *what, lua_Debug *ar);

Returns information about a specific function or function invocation.

To get information about a function invocation, the parameter ar must be a valid activation record that was filled by a previous call to lua_getstack or given as argument to a hook (see lua_Hook).

To get information about a function you push it onto the stack and start the what string with the character '>'. (In that case, lua_getinfo pops the function in the top of the stack.) For instance, to know in which line a function f was defined, you can write the following code: 

     lua_Debug ar;
     lua_getfield(L, LUA_GLOBALSINDEX, "f");  /* get global 'f' */
     lua_getinfo(L, ">S", &ar);
     printf("%d\n", ar.linedefined);

Each character in the string what selects some fields of the structure ar to be filled or a value to be pushed on the stack:

  • 'n': fills in the field name and namewhat;
  • 'S': fills in the fields source, short_src, linedefined, lastlinedefined, and what;
  • 'l': fills in the field currentline;
  • 'u': fills in the field nups;
  • 'f': pushes onto the stack the function that is running at the given level;
  • 'L': pushes onto the stack a table whose indices are the numbers of the lines that are valid on the function. (A valid line is a line with some associated code, that is, a line where you can put a break point. Non-valid lines include empty lines and comments.)

This function returns 0 on error (for instance, an invalid option in what).

lua_getlocal

[-0, +(0|1), -] 

const char *lua_getlocal (lua_State *L, lua_Debug *ar, int n);

Gets information about a local variable of a given activation record. The parameter ar must be a valid activation record that was filled by a previous call to lua_getstack or given as argument to a hook (see lua_Hook). The index n selects which local variable to inspect (1 is the first parameter or active local variable, and so on, until the last active local variable). lua_getlocal pushes the variable's value onto the stack and returns its name.

Variable names starting with '(' (open parentheses) represent internal variables (loop control variables, temporaries, and C function locals).

Returns NULL (and pushes nothing) when the index is greater than the number of active local variables.

lua_getstack

[-0, +0, -] 

int lua_getstack (lua_State *L, int level, lua_Debug *ar);

Get information about the interpreter runtime stack.

This function fills parts of a lua_Debug structure with an identification of the activation record of the function executing at a given level. Level 0 is the current running function, whereas level n+1 is the function that has called level n. When there are no errors, lua_getstack returns 1; when called with a level greater than the stack depth, it returns 0.

lua_getupvalue

[-0, +(0|1), -] 

const char *lua_getupvalue (lua_State *L, int funcindex, int n);

Gets information about a closure's upvalue. (For Lua functions, upvalues are the external local variables that the function uses, and that are consequently included in its closure.) lua_getupvalue gets the index n of an upvalue, pushes the upvalue's value onto the stack, and returns its name. funcindex points to the closure in the stack. (Upvalues have no particular order, as they are active through the whole function. So, they are numbered in an arbitrary order.)

Returns NULL (and pushes nothing) when the index is greater than the number of upvalues. For C functions, this function uses the empty string "" as a name for all upvalues.

lua_Hook

typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);

Type for debugging hook functions.

Whenever a hook is called, its ar argument has its field event set to the specific event that triggered the hook. Lua identifies these events with the following constants: LUA_HOOKCALL, LUA_HOOKRET, LUA_HOOKTAILRET, LUA_HOOKLINE, and LUA_HOOKCOUNT. Moreover, for line events, the field currentline is also set. To get the value of any other field in ar, the hook must call lua_getinfo. For return events, event can be LUA_HOOKRET, the normal value, or LUA_HOOKTAILRET. In the latter case, Lua is simulating a return from a function that did a tail call; in this case, it is useless to call lua_getinfo.

While Lua is running a hook, it disables other calls to hooks. Therefore, if a hook calls back Lua to execute a function or a chunk, this execution occurs without any calls to hooks.

lua_sethook

[-0, +0, -] 

int lua_sethook (lua_State *L, lua_Hook f, int mask, int count);

Sets the debugging hook function.

Argument f is the hook function. mask specifies on which events the hook will be called: it is formed by a bitwise or of the constants LUA_MASKCALL, LUA_MASKRET, LUA_MASKLINE, and LUA_MASKCOUNT. The count argument is only meaningful when the mask includes LUA_MASKCOUNT. For each event, the hook is called as explained below:

  • The call hook: is called when the interpreter calls a function. The hook is called just after Lua enters the new function, before the function gets its arguments.
  • The return hook: is called when the interpreter returns from a function. The hook is called just before Lua leaves the function. You have no access to the values to be returned by the function.
  • The line hook: is called when the interpreter is about to start the execution of a new line of code, or when it jumps back in the code (even to the same line). (This event only happens while Lua is executing a Lua function.)
  • The count hook: is called after the interpreter executes every count instructions. (This event only happens while Lua is executing a Lua function.)

A hook is disabled by setting mask to zero.

lua_setlocal

[-(0|1), +0, -] 

const char *lua_setlocal (lua_State *L, lua_Debug *ar, int n);

Sets the value of a local variable of a given activation record. Parameters ar and n are as in lua_getlocal (see lua_getlocal). lua_setlocal assigns the value at the top of the stack to the variable and returns its name. It also pops the value from the stack.

Returns NULL (and pops nothing) when the index is greater than the number of active local variables.

lua_setupvalue

[-(0|1), +0, -] 

const char *lua_setupvalue (lua_State *L, int funcindex, int n);

Sets the value of a closure's upvalue. It assigns the value at the top of the stack to the upvalue and returns its name. It also pops the value from the stack. Parameters funcindex and n are as in the lua_getupvalue (see lua_getupvalue).

Returns NULL (and pops nothing) when the index is greater than the number of upvalues.

4 - The Auxiliary Library

The auxiliary library provides several convenient functions to interface C with Lua. While the basic API provides the primitive functions for all interactions between C and Lua, the auxiliary library provides higher-level functions for some common tasks.

All functions from the auxiliary library are defined in header file lauxlib.h and have a prefix luaL_.

All functions in the auxiliary library are built on top of the basic API, and so they provide nothing that cannot be done with this API.

Several functions in the auxiliary library are used to check C function arguments. Their names are always luaL_check* or luaL_opt*. All of these functions throw an error if the check is not satisfied. Because the error message is formatted for arguments (e.g., "bad argument #1"), you should not use these functions for other stack values.

4.1 - Functions and Types

Here we list all functions and types from the auxiliary library in alphabetical order.

luaL_addchar

[-0, +0, m] 

void luaL_addchar (luaL_Buffer *B, char c);

Adds the character c to the buffer B (see luaL_Buffer).

luaL_addlstring

[-0, +0, m] 

void luaL_addlstring (luaL_Buffer *B, const char *s, size_t l);

Adds the string pointed to by s with length l to the buffer B (see luaL_Buffer). The string may contain embedded zeros.

luaL_addsize

[-0, +0, m] 

void luaL_addsize (luaL_Buffer *B, size_t n);

Adds to the buffer B (see luaL_Buffer) a string of length n previously copied to the buffer area (see luaL_prepbuffer).

luaL_addstring

[-0, +0, m] 

void luaL_addstring (luaL_Buffer *B, const char *s);

Adds the zero-terminated string pointed to by s to the buffer B (see luaL_Buffer). The string may not contain embedded zeros.

luaL_addvalue

[-1, +0, m] 

void luaL_addvalue (luaL_Buffer *B);

Adds the value at the top of the stack to the buffer B (see luaL_Buffer). Pops the value.

This is the only function on string buffers that can (and must) be called with an extra element on the stack, which is the value to be added to the buffer.

luaL_argcheck

[-0, +0, v] 

void luaL_argcheck (lua_State *L,
                    int cond,
                    int narg,
                    const char *extramsg);

Checks whether cond is true. If not, raises an error with the following message, where func is retrieved from the call stack: 

     bad argument #<narg> to <func> (<extramsg>)

luaL_argerror

[-0, +0, v] 

int luaL_argerror (lua_State *L, int narg, const char *extramsg);

Raises an error with the following message, where func is retrieved from the call stack: 

     bad argument #<narg> to <func> (<extramsg>)

This function never returns, but it is an idiom to use it in C functions as return luaL_argerror(args).

luaL_Buffer

typedef struct luaL_Buffer luaL_Buffer;

Type for a string buffer.

A string buffer allows C code to build Lua strings piecemeal. Its pattern of use is as follows:

  • First you declare a variable b of type luaL_Buffer.
  • Then you initialize it with a call luaL_buffinit(L, &b).
  • Then you add string pieces to the buffer calling any of the luaL_add* functions.
  • You finish by calling luaL_pushresult(&b). This call leaves the final string on the top of the stack.

During its normal operation, a string buffer uses a variable number of stack slots. So, while using a buffer, you cannot assume that you know where the top of the stack is. You can use the stack between successive calls to buffer operations as long as that use is balanced; that is, when you call a buffer operation, the stack is at the same level it was immediately after the previous buffer operation. (The only exception to this rule is luaL_addvalue.) After calling luaL_pushresult the stack is back to its level when the buffer was initialized, plus the final string on its top.

luaL_buffinit

[-0, +0, -] 

void luaL_buffinit (lua_State *L, luaL_Buffer *B);

Initializes a buffer B. This function does not allocate any space; the buffer must be declared as a variable (see luaL_Buffer).

luaL_callmeta

[-0, +(0|1), e] 

int luaL_callmeta (lua_State *L, int obj, const char *e);

Calls a metamethod.

If the object at index obj has a metatable and this metatable has a field e, this function calls this field and passes the object as its only argument. In this case this function returns 1 and pushes onto the stack the value returned by the call. If there is no metatable or no metamethod, this function returns 0 (without pushing any value on the stack).

luaL_checkany

[-0, +0, v] 

void luaL_checkany (lua_State *L, int narg);

Checks whether the function has an argument of any type (including nil) at position narg.

luaL_checkint

[-0, +0, v] 

int luaL_checkint (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to an int.

luaL_checkinteger

[-0, +0, v] 

lua_Integer luaL_checkinteger (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to a lua_Integer.

luaL_checklong

[-0, +0, v] 

long luaL_checklong (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number cast to a long.

luaL_checklstring

[-0, +0, v] 

const char *luaL_checklstring (lua_State *L, int narg, size_t *l);

Checks whether the function argument narg is a string and returns this string; if l is not NULL fills *l with the string's length.

This function uses lua_tolstring to get its result, so all conversions and caveats of that function apply here.

luaL_checknumber

[-0, +0, v] 

lua_Number luaL_checknumber (lua_State *L, int narg);

Checks whether the function argument narg is a number and returns this number.

luaL_checkoption

[-0, +0, v] 

int luaL_checkoption (lua_State *L,
                      int narg,
                      const char *def,
                      const char *const lst[]);

Checks whether the function argument narg is a string and searches for this string in the array lst (which must be NULL-terminated). Returns the index in the array where the string was found. Raises an error if the argument is not a string or if the string cannot be found.

If def is not NULL, the function uses def as a default value when there is no argument narg or if this argument is nil.

This is a useful function for mapping strings to C enums. (The usual convention in Lua libraries is to use strings instead of numbers to select options.)

luaL_checkstack

[-0, +0, v] 

void luaL_checkstack (lua_State *L, int sz, const char *msg);

Grows the stack size to top + sz elements, raising an error if the stack cannot grow to that size. msg is an additional text to go into the error message.

luaL_checkstring

[-0, +0, v] 

const char *luaL_checkstring (lua_State *L, int narg);

Checks whether the function argument narg is a string and returns this string.

This function uses lua_tolstring to get its result, so all conversions and caveats of that function apply here.

luaL_checktype

[-0, +0, v] 

void luaL_checktype (lua_State *L, int narg, int t);

Checks whether the function argument narg has type t. See lua_type for the encoding of types for t.

luaL_checkudata

[-0, +0, v] 

void *luaL_checkudata (lua_State *L, int narg, const char *tname);

Checks whether the function argument narg is a userdata of the type tname (see luaL_newmetatable).

luaL_dofile

[-0, +?, m] 

int luaL_dofile (lua_State *L, const char *filename);

Loads and runs the given file. It is defined as the following macro: 

     (luaL_loadfile(L, filename) || lua_pcall(L, 0, LUA_MULTRET, 0))

It returns 0 if there are no errors or 1 in case of errors.

luaL_dostring

[-0, +?, m] 

int luaL_dostring (lua_State *L, const char *str);

Loads and runs the given string. It is defined as the following macro: 

     (luaL_loadstring(L, str) || lua_pcall(L, 0, LUA_MULTRET, 0))

It returns 0 if there are no errors or 1 in case of errors.

luaL_error

[-0, +0, v] 

int luaL_error (lua_State *L, const char *fmt, ...);

Raises an error. The error message format is given by fmt plus any extra arguments, following the same rules of lua_pushfstring. It also adds at the beginning of the message the file name and the line number where the error occurred, if this information is available.

This function never returns, but it is an idiom to use it in C functions as return luaL_error(args).

luaL_getmetafield

[-0, +(0|1), m] 

int luaL_getmetafield (lua_State *L, int obj, const char *e);

Pushes onto the stack the field e from the metatable of the object at index obj. If the object does not have a metatable, or if the metatable does not have this field, returns 0 and pushes nothing.

luaL_getmetatable

[-0, +1, -] 

void luaL_getmetatable (lua_State *L, const char *tname);

Pushes onto the stack the metatable associated with name tname in the registry (see luaL_newmetatable).

luaL_gsub

[-0, +1, m] 

const char *luaL_gsub (lua_State *L,
                       const char *s,
                       const char *p,
                       const char *r);

Creates a copy of string s by replacing any occurrence of the string p with the string r. Pushes the resulting string on the stack and returns it.

luaL_loadbuffer

[-0, +1, m] 

int luaL_loadbuffer (lua_State *L,
                     const char *buff,
                     size_t sz,
                     const char *name);

Loads a buffer as a Lua chunk. This function uses lua_load to load the chunk in the buffer pointed to by buff with size sz.

This function returns the same results as lua_load. name is the chunk name, used for debug information and error messages.

luaL_loadfile

[-0, +1, m] 

int luaL_loadfile (lua_State *L, const char *filename);

Loads a file as a Lua chunk. This function uses lua_load to load the chunk in the file named filename. If filename is NULL, then it loads from the standard input. The first line in the file is ignored if it starts with a #.

This function returns the same results as lua_load, but it has an extra error code LUA_ERRFILE if it cannot open/read the file.

As lua_load, this function only loads the chunk; it does not run it.

luaL_loadstring

[-0, +1, m] 

int luaL_loadstring (lua_State *L, const char *s);

Loads a string as a Lua chunk. This function uses lua_load to load the chunk in the zero-terminated string s.

This function returns the same results as lua_load.

Also as lua_load, this function only loads the chunk; it does not run it.

luaL_newmetatable

[-0, +1, m] 

int luaL_newmetatable (lua_State *L, const char *tname);

If the registry already has the key tname, returns 0. Otherwise, creates a new table to be used as a metatable for userdata, adds it to the registry with key tname, and returns 1.

In both cases pushes onto the stack the final value associated with tname in the registry.

luaL_newstate

[-0, +0, -] 

lua_State *luaL_newstate (void);

Creates a new Lua state. It calls lua_newstate with an allocator based on the standard C realloc function and then sets a panic function (see lua_atpanic) that prints an error message to the standard error output in case of fatal errors.

Returns the new state, or NULL if there is a memory allocation error.

luaL_openlibs

[-0, +0, m] 

void luaL_openlibs (lua_State *L);

Opens all standard Lua libraries into the given state.

luaL_optint

[-0, +0, v] 

int luaL_optint (lua_State *L, int narg, int d);

If the function argument narg is a number, returns this number cast to an int. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optinteger

[-0, +0, v] 

lua_Integer luaL_optinteger (lua_State *L,
                             int narg,
                             lua_Integer d);

If the function argument narg is a number, returns this number cast to a lua_Integer. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optlong

[-0, +0, v] 

long luaL_optlong (lua_State *L, int narg, long d);

If the function argument narg is a number, returns this number cast to a long. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optlstring

[-0, +0, v] 

const char *luaL_optlstring (lua_State *L,
                             int narg,
                             const char *d,
                             size_t *l);

If the function argument narg is a string, returns this string. If this argument is absent or is nil, returns d. Otherwise, raises an error.

If l is not NULL, fills the position *l with the results's length.

luaL_optnumber

[-0, +0, v] 

lua_Number luaL_optnumber (lua_State *L, int narg, lua_Number d);

If the function argument narg is a number, returns this number. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_optstring

[-0, +0, v] 

const char *luaL_optstring (lua_State *L,
                            int narg,
                            const char *d);

If the function argument narg is a string, returns this string. If this argument is absent or is nil, returns d. Otherwise, raises an error.

luaL_prepbuffer

[-0, +0, -] 

char *luaL_prepbuffer (luaL_Buffer *B);

Returns an address to a space of size LUAL_BUFFERSIZE where you can copy a string to be added to buffer B (see luaL_Buffer). After copying the string into this space you must call luaL_addsize with the size of the string to actually add it to the buffer.

luaL_pushresult

[-?, +1, m] 

void luaL_pushresult (luaL_Buffer *B);

Finishes the use of buffer B leaving the final string on the top of the stack.

luaL_ref

[-1, +0, m] 

int luaL_ref (lua_State *L, int t);

Creates and returns a reference, in the table at index t, for the object at the top of the stack (and pops the object).

A reference is a unique integer key. As long as you do not manually add integer keys into table t, luaL_ref ensures the uniqueness of the key it returns. You can retrieve an object referred by reference r by calling lua_rawgeti(L, t, r). Function luaL_unref frees a reference and its associated object.

If the object at the top of the stack is nil, luaL_ref returns the constant LUA_REFNIL. The constant LUA_NOREF is guaranteed to be different from any reference returned by luaL_ref.

luaL_Reg

typedef struct luaL_Reg {
  const char *name;
  lua_CFunction func;
} luaL_Reg;

Type for arrays of functions to be registered by luaL_register. name is the function name and func is a pointer to the function. Any array of luaL_Reg must end with an sentinel entry in which both name and func are NULL.

luaL_register

[-(0|1), +1, m] 

void luaL_register (lua_State *L,
                    const char *libname,
                    const luaL_Reg *l);

Opens a library.

When called with libname equal to NULL, it simply registers all functions in the list l (see luaL_Reg) into the table on the top of the stack.

When called with a non-null libname, luaL_register creates a new table t, sets it as the value of the global variable libname, sets it as the value of package.loaded[libname], and registers on it all functions in the list l. If there is a table in package.loaded[libname] or in variable libname, reuses this table instead of creating a new one.

In any case the function leaves the table on the top of the stack.

luaL_typename

[-0, +0, -] 

const char *luaL_typename (lua_State *L, int index);

Returns the name of the type of the value at the given index.

luaL_typerror

[-0, +0, v] 

int luaL_typerror (lua_State *L, int narg, const char *tname);

Generates an error with a message like the following: 

     location: bad argument narg to 'func' (tname expected, got rt)

where location is produced by luaL_where, func is the name of the current function, and rt is the type name of the actual argument.

luaL_unref

[-0, +0, -] 

void luaL_unref (lua_State *L, int t, int ref);

Releases reference ref from the table at index t (see luaL_ref). The entry is removed from the table, so that the referred object can be collected. The reference ref is also freed to be used again.

If ref is LUA_NOREF or LUA_REFNIL, luaL_unref does nothing.

luaL_where

[-0, +1, m] 

void luaL_where (lua_State *L, int lvl);

Pushes onto the stack a string identifying the current position of the control at level lvl in the call stack. Typically this string has the following format: 

     chunkname:currentline:

Level 0 is the running function, level 1 is the function that called the running function, etc.

This function is used to build a prefix for error messages.

5 - Standard Libraries

The standard Lua libraries provide useful functions that are implemented directly through the C API. Some of these functions provide essential services to the language (e.g., type and getmetatable); others provide access to "outside" services (e.g., I/O); and others could be implemented in Lua itself, but are quite useful or have critical performance requirements that deserve an implementation in C (e.g., table.sort).

All libraries are implemented through the official C API and are provided as separate C modules. Currently, Lua has the following standard libraries:

  • basic library, which includes the coroutine sub-library;
  • package library;
  • string manipulation;
  • table manipulation;
  • mathematical functions (sin, log, etc.);
  • input and output;
  • operating system facilities;
  • debug facilities.

Except for the basic and package libraries, each library provides all its functions as fields of a global table or as methods of its objects.

To have access to these libraries, the C host program should call the luaL_openlibs function, which opens all standard libraries. Alternatively, it can open them individually by calling luaopen_base (for the basic library), luaopen_package (for the package library), luaopen_string (for the string library), luaopen_table (for the table library), luaopen_math (for the mathematical library), luaopen_io (for the I/O library), luaopen_os (for the Operating System library), and luaopen_debug (for the debug library). These functions are declared in lualib.h and should not be called directly: you must call them like any other Lua C function, e.g., by using lua_call.

5.1 - Basic Functions

The basic library provides some core functions to Lua. If you do not include this library in your application, you should check carefully whether you need to provide implementations for some of its facilities.

assert (v [, message])

Issues an error when the value of its argument v is false (i.e., nil or false); otherwise, returns all its arguments. message is an error message; when absent, it defaults to "assertion failed!"

collectgarbage ([opt [, arg]])

This function is a generic interface to the garbage collector. It performs different functions according to its first argument, opt:

  • "collect": performs a full garbage-collection cycle. This is the default option.
  • "stop": stops the garbage collector.
  • "restart": restarts the garbage collector.
  • "count": returns the total memory in use by Lua (in Kbytes).
  • "step": performs a garbage-collection step. The step "size" is controlled by arg (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of arg. Returns true if the step finished a collection cycle.
  • "setpause": sets arg as the new value for the pause of the collector (see §2.10). Returns the previous value for pause.
  • "setstepmul": sets arg as the new value for the step multiplier of the collector (see §2.10). Returns the previous value for step.

dofile ([filename])

Opens the named file and executes its contents as a Lua chunk. When called without arguments, dofile executes the contents of the standard input (stdin). Returns all values returned by the chunk. In case of errors, dofile propagates the error to its caller (that is, dofile does not run in protected mode).

error (message [, level])

Terminates the last protected function called and returns message as the error message. Function error never returns.

Usually, error adds some information about the error position at the beginning of the message. The level argument specifies how to get the error position. With level 1 (the default), the error position is where the error function was called. Level 2 points the error to where the function that called error was called; and so on. Passing a level 0 avoids the addition of error position information to the message.

_G

A global variable (not a function) that holds the global environment (that is, _G._G = _G). Lua itself does not use this variable; changing its value does not affect any environment, nor vice-versa. (Use setfenv to change environments.)

getfenv ([f])

Returns the current environment in use by the function. f can be a Lua function or a number that specifies the function at that stack level: Level 1 is the function calling getfenv. If the given function is not a Lua function, or if f is 0, getfenv returns the global environment. The default for f is 1.

getmetatable (object)

If object does not have a metatable, returns nil. Otherwise, if the object's metatable has a "__metatable" field, returns the associated value. Otherwise, returns the metatable of the given object.

ipairs (t)

Returns three values: an iterator function, the table t, and 0, so that the construction 

     for i,v in ipairs(t) do body end

will iterate over the pairs (1,t[1]), (2,t[2]), ···, up to the first integer key absent from the table.

load (func [, chunkname])

Loads a chunk using function func to get its pieces. Each call to func must return a string that concatenates with previous results. A return of an empty string, nil, or no value signals the end of the chunk.

If there are no errors, returns the compiled chunk as a function; otherwise, returns nil plus the error message. The environment of the returned function is the global environment.

chunkname is used as the chunk name for error messages and debug information. When absent, it defaults to "=(load)".

loadfile ([filename])

Similar to load, but gets the chunk from file filename or from the standard input, if no file name is given.

loadstring (string [, chunkname])

Similar to load, but gets the chunk from the given string.

To load and run a given string, use the idiom 

     assert(loadstring(s))()

When absent, chunkname defaults to the given string.

next (table [, index])

Allows a program to traverse all fields of a table. Its first argument is a table and its second argument is an index in this table. next returns the next index of the table and its associated value. When called with nil as its second argument, next returns an initial index and its associated value. When called with the last index, or with nil in an empty table, next returns nil. If the second argument is absent, then it is interpreted as nil. In particular, you can use next(t) to check whether a table is empty.

The order in which the indices are enumerated is not specified, even for numeric indices. (To traverse a table in numeric order, use a numerical for or the ipairs function.)

The behavior of next is undefined if, during the traversal, you assign any value to a non-existent field in the table. You may however modify existing fields. In particular, you may clear existing fields.

pairs (t)

Returns three values: the next function, the table t, and nil, so that the construction 

     for k,v in pairs(t) do body end

will iterate over all key–value pairs of table t.

See function next for the caveats of modifying the table during its traversal.

pcall (f, arg1, ···)

Calls function f with the given arguments in protected mode. This means that any error inside f is not propagated; instead, pcall catches the error and returns a status code. Its first result is the status code (a boolean), which is true if the call succeeds without errors. In such case, pcall also returns all results from the call, after this first result. In case of any error, pcall returns false plus the error message.

print (···)

Receives any number of arguments, and prints their values to stdout, using the tostring function to convert them to strings. print is not intended for formatted output, but only as a quick way to show a value, typically for debugging. For formatted output, use string.format.

rawequal (v1, v2)

Checks whether v1 is equal to v2, without invoking any metamethod. Returns a boolean.

rawget (table, index)

Gets the real value of table[index], without invoking any metamethod. table must be a table; index may be any value.

rawset (table, index, value)

Sets the real value of table[index] to value, without invoking any metamethod. table must be a table, index any value different from nil, and value any Lua value.

This function returns table.

select (index, ···)

If index is a number, returns all arguments after argument number index. Otherwise, index must be the string "#", and select returns the total number of extra arguments it received.

setfenv (f, table)

Sets the environment to be used by the given function. f can be a Lua function or a number that specifies the function at that stack level: Level 1 is the function calling setfenv. setfenv returns the given function.

As a special case, when f is 0 setfenv changes the environment of the running thread. In this case, setfenv returns no values.

setmetatable (table, metatable)

Sets the metatable for the given table. (You cannot change the metatable of other types from Lua, only from C.) If metatable is nil, removes the metatable of the given table. If the original metatable has a "__metatable" field, raises an error.

This function returns table.

tonumber (e [, base])

Tries to convert its argument to a number. If the argument is already a number or a string convertible to a number, then tonumber returns this number; otherwise, it returns nil.

An optional argument specifies the base to interpret the numeral. The base may be any integer between 2 and 36, inclusive. In bases above 10, the letter 'A' (in either upper or lower case) represents 10, 'B' represents 11, and so forth, with 'Z' representing 35. In base 10 (the default), the number can have a decimal part, as well as an optional exponent part (see §2.1). In other bases, only unsigned integers are accepted.

tostring (e)

Receives an argument of any type and converts it to a string in a reasonable format. For complete control of how numbers are converted, use string.format.

If the metatable of e has a "__tostring" field, then tostring calls the corresponding value with e as argument, and uses the result of the call as its result.

type (v)

Returns the type of its only argument, coded as a string. The possible results of this function are "nil" (a string, not the value nil), "number", "string", "boolean", "table", "function", "thread", and "userdata".

unpack (list [, i [, j]])

Returns the elements from the given table. This function is equivalent to 
     return list[i], list[i+1], ···, list[j]

except that the above code can be written only for a fixed number of elements. By default, i is 1 and j is the length of the list, as defined by the length operator (see §2.5.5).

_VERSION

A global variable (not a function) that holds a string containing the current interpreter version. The current contents of this variable is "Lua 5.1".

xpcall (f, err)

This function is similar to pcall, except that you can set a new error handler.

xpcall calls function f in protected mode, using err as the error handler. Any error inside f is not propagated; instead, xpcall catches the error, calls the err function with the original error object, and returns a status code. Its first result is the status code (a boolean), which is true if the call succeeds without errors. In this case, xpcall also returns all results from the call, after this first result. In case of any error, xpcall returns false plus the result from err.

5.2 - Coroutine Manipulation

The operations related to coroutines comprise a sub-library of the basic library and come inside the table coroutine. See §2.11 for a general description of coroutines.

coroutine.create (f)

Creates a new coroutine, with body f. f must be a Lua function. Returns this new coroutine, an object with type "thread".

coroutine.resume (co [, val1, ···])

Starts or continues the execution of coroutine co. The first time you resume a coroutine, it starts running its body. The values val1, ··· are passed as the arguments to the body function. If the coroutine has yielded, resume restarts it; the values val1, ··· are passed as the results from the yield.

If the coroutine runs without any errors, resume returns true plus any values passed to yield (if the coroutine yields) or any values returned by the body function (if the coroutine terminates). If there is any error, resume returns false plus the error message.

coroutine.running ()

Returns the running coroutine, or nil when called by the main thread.

coroutine.status (co)

Returns the status of coroutine co, as a string: "running", if the coroutine is running (that is, it called status); "suspended", if the coroutine is suspended in a call to yield, or if it has not started running yet; "normal" if the coroutine is active but not running (that is, it has resumed another coroutine); and "dead" if the coroutine has finished its body function, or if it has stopped with an error.

coroutine.wrap (f)

Creates a new coroutine, with body f. f must be a Lua function. Returns a function that resumes the coroutine each time it is called. Any arguments passed to the function behave as the extra arguments to resume. Returns the same values returned by resume, except the first boolean. In case of error, propagates the error.

coroutine.yield (···)

Suspends the execution of the calling coroutine. The coroutine cannot be running a C function, a metamethod, or an iterator. Any arguments to yield are passed as extra results to resume.

5.3 - Modules

The package library provides basic facilities for loading and building modules in Lua. It exports two of its functions directly in the global environment: require and module. Everything else is exported in a table package.

module (name [, ···])

Creates a module. If there is a table in package.loaded[name], this table is the module. Otherwise, if there is a global table t with the given name, this table is the module. Otherwise creates a new table t and sets it as the value of the global name and the value of package.loaded[name]. This function also initializes t._NAME with the given name, t._M with the module (t itself), and t._PACKAGE with the package name (the full module name minus last component; see below). Finally, module sets t as the new environment of the current function and the new value of package.loaded[name], so that require returns t.

If name is a compound name (that is, one with components separated by dots), module creates (or reuses, if they already exist) tables for each component. For instance, if name is a.b.c, then module stores the module table in field c of field b of global a.

This function can receive optional options after the module name, where each option is a function to be applied over the module.

require (modname)

Loads the given module. The function starts by looking into the package.loaded table to determine whether modname is already loaded. If it is, then require returns the value stored at package.loaded[modname]. Otherwise, it tries to find a loader for the module.

To find a loader, require is guided by the package.loaders array. By changing this array, we can change how require looks for a module. The following explanation is based on the default configuration for package.loaders.

First require queries package.preload[modname]. If it has a value, this value (which should be a function) is the loader. Otherwise require searches for a Lua loader using the path stored in package.path. If that also fails, it searches for a C loader using the path stored in package.cpath. If that also fails, it tries an all-in-one loader (see package.loaders).

Once a loader is found, require calls the loader with a single argument, modname. If the loader returns any value, require assigns the returned value to package.loaded[modname]. If the loader returns no value and has not assigned any value to package.loaded[modname], then require assigns true to this entry. In any case, require returns the final value of package.loaded[modname].

If there is any error loading or running the module, or if it cannot find any loader for the module, then require signals an error.

package.cpath

The path used by require to search for a C loader.

Lua initializes the C path package.cpath in the same way it initializes the Lua path package.path, using the environment variable LUA_CPATH or a default path defined in luaconf.h.

package.loaded

A table used by require to control which modules are already loaded. When you require a module modname and package.loaded[modname] is not false, require simply returns the value stored there.

package.loaders

A table used by require to control how to load modules.

Each entry in this table is a searcher function. When looking for a module, require calls each of these searchers in ascending order, with the module name (the argument given to require) as its sole parameter. The function can return another function (the module loader) or a string explaining why it did not find that module (or nil if it has nothing to say). Lua initializes this table with four functions.

The first searcher simply looks for a loader in the package.preload table.

The second searcher looks for a loader as a Lua library, using the path stored at package.path. A path is a sequence of templates separated by semicolons. For each template, the searcher will change each interrogation mark in the template by filename, which is the module name with each dot replaced by a "directory separator" (such as "/" in Unix); then it will try to open the resulting file name. So, for instance, if the Lua path is the string 

     "./?.lua;./?.lc;/usr/local/?/init.lua"

the search for a Lua file for module foo will try to open the files ./foo.lua, ./foo.lc, and /usr/local/foo/init.lua, in that order.

The third searcher looks for a loader as a C library, using the path given by the variable package.cpath. For instance, if the C path is the string 

     "./?.so;./?.dll;/usr/local/?/init.so"

the searcher for module foo will try to open the files ./foo.so, ./foo.dll, and /usr/local/foo/init.so, in that order. Once it finds a C library, this searcher first uses a dynamic link facility to link the application with the library. Then it tries to find a C function inside the library to be used as the loader. The name of this C function is the string "luaopen_" concatenated with a copy of the module name where each dot is replaced by an underscore. Moreover, if the module name has a hyphen, its prefix up to (and including) the first hyphen is removed. For instance, if the module name is a.v1-b.c, the function name will be luaopen_b_c.

The fourth searcher tries an all-in-one loader. It searches the C path for a library for the root name of the given module. For instance, when requiring a.b.c, it will search for a C library for a. If found, it looks into it for an open function for the submodule; in our example, that would be luaopen_a_b_c. With this facility, a package can pack several C submodules into one single library, with each submodule keeping its original open function.

package.loadlib (libname, funcname)

Dynamically links the host program with the C library libname. Inside this library, looks for a function funcname and returns this function as a C function. (So, funcname must follow the protocol (see lua_CFunction)).

This is a low-level function. It completely bypasses the package and module system. Unlike require, it does not perform any path searching and does not automatically adds extensions. libname must be the complete file name of the C library, including if necessary a path and extension. funcname must be the exact name exported by the C library (which may depend on the C compiler and linker used).

This function is not supported by ANSI C. As such, it is only available on some platforms (Windows, Linux, Mac OS X, Solaris, BSD, plus other Unix systems that support the dlfcn standard).

package.path

The path used by require to search for a Lua loader.

At start-up, Lua initializes this variable with the value of the environment variable LUA_PATH or with a default path defined in luaconf.h, if the environment variable is not defined. Any ";;" in the value of the environment variable is replaced by the default path.

package.preload

A table to store loaders for specific modules (see require).

package.seeall (module)

Sets a metatable for module with its __index field referring to the global environment, so that this module inherits values from the global environment. To be used as an option to function module.

5.4 - String Manipulation

This library provides generic functions for string manipulation, such as finding and extracting substrings, and pattern matching. When indexing a string in Lua, the first character is at position 1 (not at 0, as in C). Indices are allowed to be negative and are interpreted as indexing backwards, from the end of the string. Thus, the last character is at position -1, and so on.

The string library provides all its functions inside the table string. It also sets a metatable for strings where the __index field points to the string table. Therefore, you can use the string functions in object-oriented style. For instance, string.byte(s, i) can be written as s:byte(i).

The string library assumes one-byte character encodings.

string.byte (s [, i [, j]])

Returns the internal numerical codes of the characters s[i], s[i+1], ···, s[j]. The default value for i is 1; the default value for j is i.

Note that numerical codes are not necessarily portable across platforms.

string.char (···)

Receives zero or more integers. Returns a string with length equal to the number of arguments, in which each character has the internal numerical code equal to its corresponding argument.

Note that numerical codes are not necessarily portable across platforms.

string.dump (function)

Returns a string containing a binary representation of the given function, so that a later loadstring on this string returns a copy of the function. function must be a Lua function without upvalues.

string.find (s, pattern [, init [, plain]])

Looks for the first match of pattern in the string s. If it finds a match, then find returns the indices of s where this occurrence starts and ends; otherwise, it returns nil. A third, optional numerical argument init specifies where to start the search; its default value is 1 and can be negative. A value of true as a fourth, optional argument plain turns off the pattern matching facilities, so the function does a plain "find substring" operation, with no characters in pattern being considered "magic". Note that if plain is given, then init must be given as well.

If the pattern has captures, then in a successful match the captured values are also returned, after the two indices.

string.format (formatstring, ···)

Returns a formatted version of its variable number of arguments following the description given in its first argument (which must be a string). The format string follows the same rules as the printf family of standard C functions. The only differences are that the options/modifiers *, l, L, n, p, and h are not supported and that there is an extra option, q. The q option formats a string in a form suitable to be safely read back by the Lua interpreter: the string is written between double quotes, and all double quotes, newlines, embedded zeros, and backslashes in the string are correctly escaped when written. For instance, the call 
     string.format('%q', 'a string with "quotes" and \n new line')

will produce the string: 

     "a string with \"quotes\" and \
      new line"

The options c, d, E, e, f, g, G, i, o, u, X, and x all expect a number as argument, whereas q and s expect a string.

This function does not accept string values containing embedded zeros, except as arguments to the q option.

string.gmatch (s, pattern)

Returns an iterator function that, each time it is called, returns the next captures from pattern over string s. If pattern specifies no captures, then the whole match is produced in each call.

As an example, the following loop 

     s = "hello world from Lua"
     for w in string.gmatch(s, "%a+") do
       print(w)
     end

will iterate over all the words from string s, printing one per line. The next example collects all pairs key=value from the given string into a table: 

     t = {}
     s = "from=world, to=Lua"
     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
       t[k] = v
     end

For this function, a '^' at the start of a pattern does not work as an anchor, as this would prevent the iteration.

string.gsub (s, pattern, repl [, n])

Returns a copy of s in which all (or the first n, if given) occurrences of the pattern have been replaced by a replacement string specified by repl, which can be a string, a table, or a function. gsub also returns, as its second value, the total number of matches that occurred.

If repl is a string, then its value is used for replacement. The character % works as an escape character: any sequence in repl of the form %n, with n between 1 and 9, stands for the value of the n-th captured substring (see below). The sequence %0 stands for the whole match. The sequence %% stands for a single %.

If repl is a table, then the table is queried for every match, using the first capture as the key; if the pattern specifies no captures, then the whole match is used as the key.

If repl is a function, then this function is called every time a match occurs, with all captured substrings passed as arguments, in order; if the pattern specifies no captures, then the whole match is passed as a sole argument.

If the value returned by the table query or by the function call is a string or a number, then it is used as the replacement string; otherwise, if it is false or nil, then there is no replacement (that is, the original match is kept in the string).

Here are some examples: 

     x = string.gsub("hello world", "(%w+)", "%1 %1")
     --> x="hello hello world world"
     
     x = string.gsub("hello world", "%w+", "%0 %0", 1)
     --> x="hello hello world"
     
     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
     --> x="world hello Lua from"
     
     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
     --> x="home = /home/roberto, user = roberto"
     
     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
           return loadstring(s)()
         end)
     --> x="4+5 = 9"
     
     local t = {name="lua", version="5.1"}
     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
     --> x="lua-5.1.tar.gz"

string.len (s)

Receives a string and returns its length. The empty string "" has length 0. Embedded zeros are counted, so "a\000bc\000" has length 5.

string.lower (s)

Receives a string and returns a copy of this string with all uppercase letters changed to lowercase. All other characters are left unchanged. The definition of what an uppercase letter is depends on the current locale.

string.match (s, pattern [, init])

Looks for the first match of pattern in the string s. If it finds one, then match returns the captures from the pattern; otherwise it returns nil. If pattern specifies no captures, then the whole match is returned. A third, optional numerical argument init specifies where to start the search; its default value is 1 and can be negative.

string.rep (s, n)

Returns a string that is the concatenation of n copies of the string s.

string.reverse (s)

Returns a string that is the string s reversed.

string.sub (s, i [, j])

Returns the substring of s that starts at i and continues until j; i and j can be negative. If j is absent, then it is assumed to be equal to -1 (which is the same as the string length). In particular, the call string.sub(s,1,j) returns a prefix of s with length j, and string.sub(s, -i) returns a suffix of s with length i.

string.upper (s)

Receives a string and returns a copy of this string with all lowercase letters changed to uppercase. All other characters are left unchanged. The definition of what a lowercase letter is depends on the current locale.

5.4.1 - Patterns

Character Class:

A character class is used to represent a set of characters. The following combinations are allowed in describing a character class:

  • x: (where x is not one of the magic characters ^$()%.[]*+-?) represents the character x itself.
  • .: (a dot) represents all characters.
  • %a: represents all letters.
  • %c: represents all control characters.
  • %d: represents all digits.
  • %l: represents all lowercase letters.
  • %p: represents all punctuation characters.
  • %s: represents all space characters.
  • %u: represents all uppercase letters.
  • %w: represents all alphanumeric characters.
  • %x: represents all hexadecimal digits.
  • %z: represents the character with representation 0.
  • %x: (where x is any non-alphanumeric character) represents the character x. This is the standard way to escape the magic characters. Any punctuation character (even the non magic) can be preceded by a '%' when used to represent itself in a pattern.
  • [set]: represents the class which is the union of all characters in set. A range of characters can be specified by separating the end characters of the range with a '-'. All classes %x described above can also be used as components in set. All other characters in set represent themselves. For example, [%w_] (or [_%w]) represents all alphanumeric characters plus the underscore, [0-7] represents the octal digits, and [0-7%l%-] represents the octal digits plus the lowercase letters plus the '-' character.

    The interaction between ranges and classes is not defined. Therefore, patterns like [%a-z] or [a-%%] have no meaning.

  • [^set]: represents the complement of set, where set is interpreted as above.

For all classes represented by single letters (%a, %c, etc.), the corresponding uppercase letter represents the complement of the class. For instance, %S represents all non-space characters.

The definitions of letter, space, and other character groups depend on the current locale. In particular, the class [a-z] may not be equivalent to %l.

Pattern Item:

A pattern item can be

  • a single character class, which matches any single character in the class;
  • a single character class followed by '*', which matches 0 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence;
  • a single character class followed by '+', which matches 1 or more repetitions of characters in the class. These repetition items will always match the longest possible sequence;
  • a single character class followed by '-', which also matches 0 or more repetitions of characters in the class. Unlike '*', these repetition items will always match the shortest possible sequence;
  • a single character class followed by '?', which matches 0 or 1 occurrence of a character in the class;
  • %n, for n between 1 and 9; such item matches a substring equal to the n-th captured string (see below);
  • %bxy, where x and y are two distinct characters; such item matches strings that start with x, end with y, and where the x and y are balanced. This means that, if one reads the string from left to right, counting +1 for an x and -1 for a y, the ending y is the first y where the count reaches 0. For instance, the item %b() matches expressions with balanced parentheses.

Pattern:

A pattern is a sequence of pattern items. A '^' at the beginning of a pattern anchors the match at the beginning of the subject string. A '$' at the end of a pattern anchors the match at the end of the subject string. At other positions, '^' and '$' have no special meaning and represent themselves.

Captures:

A pattern can contain sub-patterns enclosed in parentheses; they describe captures. When a match succeeds, the substrings of the subject string that match captures are stored (captured) for future use. Captures are numbered according to their left parentheses. For instance, in the pattern "(a*(.)%w(%s*))", the part of the string matching "a*(.)%w(%s*)" is stored as the first capture (and therefore has number 1); the character matching "." is captured with number 2, and the part matching "%s*" has number 3.

As a special case, the empty capture () captures the current string position (a number). For instance, if we apply the pattern "()aa()" on the string "flaaap", there will be two captures: 3 and 5.

A pattern cannot contain embedded zeros. Use %z instead.

5.5 - Table Manipulation

This library provides generic functions for table manipulation. It provides all its functions inside the table table.

Most functions in the table library assume that the table represents an array or a list. For these functions, when we talk about the "length" of a table we mean the result of the length operator.

table.concat (table [, sep [, i [, j]]])

Given an array where all elements are strings or numbers, returns table[i]..sep..table[i+1] ··· sep..table[j]. The default value for sep is the empty string, the default for i is 1, and the default for j is the length of the table. If i is greater than j, returns the empty string.

table.insert (table, [pos,] value)

Inserts element value at position pos in table, shifting up other elements to open space, if necessary. The default value for pos is n+1, where n is the length of the table (see §2.5.5), so that a call table.insert(t,x) inserts x at the end of table t.

table.maxn (table)

Returns the largest positive numerical index of the given table, or zero if the table has no positive numerical indices. (To do its job this function does a linear traversal of the whole table.)

table.remove (table [, pos])

Removes from table the element at position pos, shifting down other elements to close the space, if necessary. Returns the value of the removed element. The default value for pos is n, where n is the length of the table, so that a call table.remove(t) removes the last element of table t.

table.sort (table [, comp])

Sorts table elements in a given order, in-place, from table[1] to table[n], where n is the length of the table. If comp is given, then it must be a function that receives two table elements, and returns true when the first is less than the second (so that not comp(a[i+1],a[i]) will be true after the sort). If comp is not given, then the standard Lua operator < is used instead.

The sort algorithm is not stable; that is, elements considered equal by the given order may have their relative positions changed by the sort.

5.6 - Mathematical Functions

This library is an interface to the standard C math library. It provides all its functions inside the table math.

math.abs (x)

Returns the absolute value of x.

math.acos (x)

Returns the arc cosine of x (in radians).

math.asin (x)

Returns the arc sine of x (in radians).

math.atan (x)

Returns the arc tangent of x (in radians).

Returns the angle x (given in degrees) in radians.

math.random ([m [, n]])

This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. (No guarantees can be given for its statistical properties.)

When called without arguments, returns a uniform pseudo-random real number in the range [0,1). When called with an integer number m, math.random returns a uniform pseudo-random integer in the range [1, m]. When called with two integer numbers m and n, math.random returns a uniform pseudo-random integer in the range [m, n].

math.randomseed (x)

Sets x as the "seed" for the pseudo-random generator: equal seeds produce equal sequences of numbers.

math.sin (x)

Returns the sine of x (assumed to be in radians).

math.sinh (x)

Returns the hyperbolic sine of x.

math.sqrt (x)

Returns the square root of x. (You can also use the expression x^0.5 to compute this value.)

math.tan (x)

Returns the tangent of x (assumed to be in radians).

math.tanh (x)

Returns the hyperbolic tangent of x.

5.7 - Input and Output Facilities

The I/O library provides two different styles for file manipulation. The first one uses implicit file descriptors; that is, there are operations to set a default input file and a default output file, and all input/output operations are over these default files. The second style uses explicit file descriptors.

When using implicit file descriptors, all operations are supplied by table io. When using explicit file descriptors, the operation io.open returns a file descriptor and then all operations are supplied as methods of the file descriptor.

The table io also provides three predefined file descriptors with their usual meanings from C: io.stdin, io.stdout, and io.stderr. The I/O library never closes these files.

Unless otherwise stated, all I/O functions return nil on failure (plus an error message as a second result and a system-dependent error code as a third result) and some value different from nil on success.

io.close ([file])

Equivalent to file:close(). Without a file, closes the default output file.

io.flush ()

Equivalent to file:flush over the default output file.

io.input ([file])

When called with a file name, it opens the named file (in text mode), and sets its handle as the default input file. When called with a file handle, it simply sets this file handle as the default input file. When called without parameters, it returns the current default input file.

In case of errors this function raises the error, instead of returning an error code.

io.lines ([filename])

Opens the given file name in read mode and returns an iterator function that, each time it is called, returns a new line from the file. Therefore, the construction 

     for line in io.lines(filename) do body end

will iterate over all lines of the file. When the iterator function detects the end of file, it returns nil (to finish the loop) and automatically closes the file.

The call io.lines() (with no file name) is equivalent to io.input():lines(); that is, it iterates over the lines of the default input file. In this case it does not close the file when the loop ends.

io.open (filename [, mode])

This function opens a file, in the mode specified in the string mode. It returns a new file handle, or, in case of errors, nil plus an error message.

The mode string can be any of the following:

  • "r": read mode (the default);
  • "w": write mode;
  • "a": append mode;
  • "r+": update mode, all previous data is preserved;
  • "w+": update mode, all previous data is erased;
  • "a+": append update mode, previous data is preserved, writing is only allowed at the end of file.

The mode string can also have a 'b' at the end, which is needed in some systems to open the file in binary mode. This string is exactly what is used in the standard C function fopen.

io.output ([file])

Similar to io.input, but operates over the default output file.

io.popen (prog [, mode])

Starts program prog in a separated process and returns a file handle that you can use to read data from this program (if mode is "r", the default) or to write data to this program (if mode is "w").

This function is system dependent and is not available on all platforms.

io.read (···)

Equivalent to io.input():read.

io.tmpfile ()

Returns a handle for a temporary file. This file is opened in update mode and it is automatically removed when the program ends.

io.type (obj)

Checks whether obj is a valid file handle. Returns the string "file" if obj is an open file handle, "closed file" if obj is a closed file handle, or nil if obj is not a file handle.

io.write (···)

Equivalent to io.output():write.

file:close ()

Closes file. Note that files are automatically closed when their handles are garbage collected, but that takes an unpredictable amount of time to happen.

file:flush ()

Saves any written data to file.

file:lines ()

Returns an iterator function that, each time it is called, returns a new line from the file. Therefore, the construction 

     for line in file:lines() do body end

will iterate over all lines of the file. (Unlike io.lines, this function does not close the file when the loop ends.)

file:read (···)

Reads the file file, according to the given formats, which specify what to read. For each format, the function returns a string (or a number) with the characters read, or nil if it cannot read data with the specified format. When called without formats, it uses a default format that reads the entire next line (see below).

The available formats are

  • "*n": reads a number; this is the only format that returns a number instead of a string.
  • "*a": reads the whole file, starting at the current position. On end of file, it returns the empty string.
  • "*l": reads the next line (skipping the end of line), returning nil on end of file. This is the default format.
  • number: reads a string with up to this number of characters, returning nil on end of file. If number is zero, it reads nothing and returns an empty string, or nil on end of file.

file:seek ([whence] [, offset])

Sets and gets the file position, measured from the beginning of the file, to the position given by offset plus a base specified by the string whence, as follows:

  • "set": base is position 0 (beginning of the file);
  • "cur": base is current position;
  • "end": base is end of file;

In case of success, function seek returns the final file position, measured in bytes from the beginning of the file. If this function fails, it returns nil, plus a string describing the error.

The default value for whence is "cur", and for offset is 0. Therefore, the call file:seek() returns the current file position, without changing it; the call file:seek("set") sets the position to the beginning of the file (and returns 0); and the call file:seek("end") sets the position to the end of the file, and returns its size.

file:setvbuf (mode [, size])

Sets the buffering mode for an output file. There are three available modes:

  • "no": no buffering; the result of any output operation appears immediately.
  • "full": full buffering; output operation is performed only when the buffer is full (or when you explicitly flush the file (see io.flush)).
  • "line": line buffering; output is buffered until a newline is output or there is any input from some special files (such as a terminal device).

For the last two cases, size specifies the size of the buffer, in bytes. The default is an appropriate size.

file:write (···)

Writes the value of each of its arguments to the file. The arguments must be strings or numbers. To write other values, use tostring or string.format before write.

5.8 - Operating System Facilities

This library is implemented through table os.

os.clock ()

Returns an approximation of the amount in seconds of CPU time used by the program.

os.date ([format [, time]])

Returns a string or a table containing date and time, formatted according to the given string format.

If the time argument is present, this is the time to be formatted (see the os.time function for a description of this value). Otherwise, date formats the current time.

If format starts with '!', then the date is formatted in Coordinated Universal Time. After this optional character, if format is the string "*t", then date returns a table with the following fields: year (four digits), month (1--12), day (1--31), hour (0--23), min (0--59), sec (0--61), wday (weekday, Sunday is 1), yday (day of the year), and isdst (daylight saving flag, a boolean).

If format is not "*t", then date returns the date as a string, formatted according to the same rules as the C function strftime.

When called without arguments, date returns a reasonable date and time representation that depends on the host system and on the current locale (that is, os.date() is equivalent to os.date("%c")).

os.difftime (t2, t1)

Returns the number of seconds from time t1 to time t2. In POSIX, Windows, and some other systems, this value is exactly t2-t1.

os.execute ([command])

This function is equivalent to the C function system. It passes command to be executed by an operating system shell. It returns a status code, which is system-dependent. If command is absent, then it returns nonzero if a shell is available and zero otherwise.

os.exit ([code])

Calls the C function exit, with an optional code, to terminate the host program. The default value for code is the success code.

os.getenv (varname)

Returns the value of the process environment variable varname, or nil if the variable is not defined.

os.remove (filename)

Deletes the file or directory with the given name. Directories must be empty to be removed. If this function fails, it returns nil, plus a string describing the error.

os.rename (oldname, newname)

Renames file or directory named oldname to newname. If this function fails, it returns nil, plus a string describing the error.

os.setlocale (locale [, category])

Sets the current locale of the program. locale is a string specifying a locale; category is an optional string describing which category to change: "all", "collate", "ctype", "monetary", "numeric", or "time"; the default category is "all". The function returns the name of the new locale, or nil if the request cannot be honored.

If locale is the empty string, the current locale is set to an implementation-defined native locale. If locale is the string "C", the current locale is set to the standard C locale.

When called with nil as the first argument, this function only returns the name of the current locale for the given category.

os.time ([table])

Returns the current time when called without arguments, or a time representing the date and time specified by the given table. This table must have fields year, month, and day, and may have fields hour, min, sec, and isdst (for a description of these fields, see the os.date function).

The returned value is a number, whose meaning depends on your system. In POSIX, Windows, and some other systems, this number counts the number of seconds since some given start time (the "epoch"). In other systems, the meaning is not specified, and the number returned by time can be used only as an argument to date and difftime.

os.tmpname ()

Returns a string with a file name that can be used for a temporary file. The file must be explicitly opened before its use and explicitly removed when no longer needed.

On some systems (POSIX), this function also creates a file with that name, to avoid security risks. (Someone else might create the file with wrong permissions in the time between getting the name and creating the file.) You still have to open the file to use it and to remove it (even if you do not use it).

When possible, you may prefer to use io.tmpfile, which automatically removes the file when the program ends.

5.9 - The Debug Library

This library provides the functionality of the debug interface to Lua programs. You should exert care when using this library. The functions provided here should be used exclusively for debugging and similar tasks, such as profiling. Please resist the temptation to use them as a usual programming tool: they can be very slow. Moreover, several of these functions violate some assumptions about Lua code (e.g., that variables local to a function cannot be accessed from outside or that userdata metatables cannot be changed by Lua code) and therefore can compromise otherwise secure code.

All functions in this library are provided inside the debug table. All functions that operate over a thread have an optional first argument which is the thread to operate over. The default is always the current thread.

debug.debug ()

Enters an interactive mode with the user, running each string that the user enters. Using simple commands and other debug facilities, the user can inspect global and local variables, change their values, evaluate expressions, and so on. A line containing only the word cont finishes this function, so that the caller continues its execution.

Note that commands for debug.debug are not lexically nested within any function, and so have no direct access to local variables.

debug.getfenv (o)

Returns the environment of object o.

debug.gethook ([thread])

Returns the current hook settings of the thread, as three values: the current hook function, the current hook mask, and the current hook count (as set by the debug.sethook function).

debug.getinfo ([thread,] function [, what])

Returns a table with information about a function. You can give the function directly, or you can give a number as the value of function, which means the function running at level function of the call stack of the given thread: level 0 is the current function (getinfo itself); level 1 is the function that called getinfo; and so on. If function is a number larger than the number of active functions, then getinfo returns nil.

The returned table can contain all the fields returned by lua_getinfo, with the string what describing which fields to fill in. The default for what is to get all information available, except the table of valid lines. If present, the option 'f' adds a field named func with the function itself. If present, the option 'L' adds a field named activelines with the table of valid lines.

For instance, the expression debug.getinfo(1,"n").name returns a table with a name for the current function, if a reasonable name can be found, and the expression debug.getinfo(print) returns a table with all available information about the print function.

debug.getlocal ([thread,] level, local)

This function returns the name and the value of the local variable with index local of the function at level level of the stack. (The first parameter or local variable has index 1, and so on, until the last active local variable.) The function returns nil if there is no local variable with the given index, and raises an error when called with a level out of range. (You can call debug.getinfo to check whether the level is valid.)

Variable names starting with '(' (open parentheses) represent internal variables (loop control variables, temporaries, and C function locals).

debug.getmetatable (object)

Returns the metatable of the given object or nil if it does not have a metatable.

debug.getregistry ()

Returns the registry table (see §3.5).

debug.getupvalue (func, up)

This function returns the name and the value of the upvalue with index up of the function func. The function returns nil if there is no upvalue with the given index.

debug.setfenv (object, table)

Sets the environment of the given object to the given table. Returns object.

debug.sethook ([thread,] hook, mask [, count])

Sets the given function as a hook. The string mask and the number count describe when the hook will be called. The string mask may have the following characters, with the given meaning:

  • "c": the hook is called every time Lua calls a function;
  • "r": the hook is called every time Lua returns from a function;
  • "l": the hook is called every time Lua enters a new line of code.

With a count different from zero, the hook is called after every count instructions.

When called without arguments, debug.sethook turns off the hook.

When the hook is called, its first parameter is a string describing the event that has triggered its call: "call", "return" (or "tail return", when simulating a return from a tail call), "line", and "count". For line events, the hook also gets the new line number as its second parameter. Inside a hook, you can call getinfo with level 2 to get more information about the running function (level 0 is the getinfo function, and level 1 is the hook function), unless the event is "tail return". In this case, Lua is only simulating the return, and a call to getinfo will return invalid data.

debug.setlocal ([thread,] level, local, value)

This function assigns the value value to the local variable with index local of the function at level level of the stack. The function returns nil if there is no local variable with the given index, and raises an error when called with a level out of range. (You can call getinfo to check whether the level is valid.) Otherwise, it returns the name of the local variable.

debug.setmetatable (object, table)

Sets the metatable for the given object to the given table (which can be nil).

debug.setupvalue (func, up, value)

This function assigns the value value to the upvalue with index up of the function func. The function returns nil if there is no upvalue with the given index. Otherwise, it returns the name of the upvalue.

debug.traceback ([thread,] [message [, level]])

Returns a string with a traceback of the call stack. An optional message string is appended at the beginning of the traceback. An optional level number tells at which level to start the traceback (default is 1, the function calling traceback).

6 - Lua Stand-alone

Although Lua has been designed as an extension language, to be embedded in a host C program, it is also frequently used as a stand-alone language. An interpreter for Lua as a stand-alone language, called simply lua, is provided with the standard distribution. The stand-alone interpreter includes all standard libraries, including the debug library. Its usage is: 

     lua [options] [script [args]]

The options are:

  • -e stat: executes string stat;
  • -l mod: "requires" mod;
  • -i: enters interactive mode after running script;
  • -v: prints version information;
  • --: stops handling options;
  • -: executes stdin as a file and stops handling options.

After handling its options, lua runs the given script, passing to it the given args as string arguments. When called without arguments, lua behaves as lua -v -i when the standard input (stdin) is a terminal, and as lua - otherwise.

Before running any argument, the interpreter checks for an environment variable LUA_INIT. If its format is @filename, then lua executes the file. Otherwise, lua executes the string itself.

All options are handled in order, except -i. For instance, an invocation like 

     $ lua -e'a=1' -e 'print(a)' script.lua

will first set a to 1, then print the value of a (which is '1'), and finally run the file script.lua with no arguments. (Here $ is the shell prompt. Your prompt may be different.)

Before starting to run the script, lua collects all arguments in the command line in a global table called arg. The script name is stored at index 0, the first argument after the script name goes to index 1, and so on. Any arguments before the script name (that is, the interpreter name plus the options) go to negative indices. For instance, in the call 

     $ lua -la b.lua t1 t2

the interpreter first runs the file a.lua, then creates a table 

     arg = { [-2] = "lua", [-1] = "-la",
             [0] = "b.lua",
             [1] = "t1", [2] = "t2" }

and finally runs the file b.lua. The script is called with arg[1], arg[2], ··· as arguments; it can also access these arguments with the vararg expression '...'.

In interactive mode, if you write an incomplete statement, the interpreter waits for its completion by issuing a different prompt.

If the global variable _PROMPT contains a string, then its value is used as the prompt. Similarly, if the global variable _PROMPT2 contains a string, its value is used as the secondary prompt (issued during incomplete statements). Therefore, both prompts can be changed directly on the command line or in any Lua programs by assigning to _PROMPT. See the next example: 

     $ lua -e"_PROMPT='myprompt> '" -i

(The outer pair of quotes is for the shell, the inner pair is for Lua.) Note the use of -i to enter interactive mode; otherwise, the program would just end silently right after the assignment to _PROMPT.

To allow the use of Lua as a script interpreter in Unix systems, the stand-alone interpreter skips the first line of a chunk if it starts with #. Therefore, Lua scripts can be made into executable programs by using chmod +x and the #! form, as in 

     #!/usr/local/bin/lua

(Of course, the location of the Lua interpreter may be different in your machine. If lua is in your PATH, then 

     #!/usr/bin/env lua

is a more portable solution.)

7 - Incompatibilities with the Previous Version

Here we list the incompatibilities that you may find when moving a program from Lua 5.0 to Lua 5.1. You can avoid most of the incompatibilities compiling Lua with appropriate options (see file luaconf.h). However, all these compatibility options will be removed in the next version of Lua.

7.1 - Changes in the Language

  • The vararg system changed from the pseudo-argument arg with a table with the extra arguments to the vararg expression. (See compile-time option LUA_COMPAT_VARARG in luaconf.h.)
  • There was a subtle change in the scope of the implicit variables of the for statement and for the repeat statement.
  • The long string/long comment syntax ([[string]]) does not allow nesting. You can use the new syntax ([=[string]=]) in these cases. (See compile-time option LUA_COMPAT_LSTR in luaconf.h.)

7.2 - Changes in the Libraries

  • Function string.gfind was renamed string.gmatch. (See compile-time option LUA_COMPAT_GFIND in luaconf.h.)
  • When string.gsub is called with a function as its third argument, whenever this function returns nil or false the replacement string is the whole match, instead of the empty string.
  • Function table.setn was deprecated. Function table.getn corresponds to the new length operator (#); use the operator instead of the function. (See compile-time option LUA_COMPAT_GETN in luaconf.h.)
  • Function loadlib was renamed package.loadlib. (See compile-time option LUA_COMPAT_LOADLIB in luaconf.h.)
  • Function math.mod was renamed math.fmod. (See compile-time option LUA_COMPAT_MOD in luaconf.h.)
  • Functions table.foreach and table.foreachi are deprecated. You can use a for loop with pairs or ipairs instead.
  • There were substantial changes in function require due to the new module system. However, the new behavior is mostly compatible with the old, but require gets the path from package.path instead of from LUA_PATH.
  • Function collectgarbage has different arguments. Function gcinfo is deprecated; use collectgarbage("count") instead.

7.3 - Changes in the API

  • The luaopen_* functions (to open libraries) cannot be called directly, like a regular C function. They must be called through Lua, like a Lua function.
  • Function lua_open was replaced by lua_newstate to allow the user to set a memory-allocation function. You can use luaL_newstate from the standard library to create a state with a standard allocation function (based on realloc).
  • Functions luaL_getn and luaL_setn (from the auxiliary library) are deprecated. Use lua_objlen instead of luaL_getn and nothing instead of luaL_setn.
  • Function luaL_openlib was replaced by luaL_register.
  • Function luaL_checkudata now throws an error when the given value is not a userdata of the expected type. (In Lua 5.0 it returned NULL.)

Use slaveof to make a Redis instance a copy of # another Redis server. A few things to understand ASAP about Redis replication. # # 1) Redis replication is asynchronous, but you can configure a master to # stop accepting writes if it appears to be not connected with at least # a given number of slaves. # 2) Redis slaves are able to perform a partial resynchronization with the # master if the replication link is lost for a relatively small amount of # time. You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. After a # network partition slaves automatically try to reconnect to masters # and resynchronize with them. # # slaveof # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the slave to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the slave request. # # masterauth # When a slave loses its connection with the master, or when the replication # is still in progress, the slave can act in two different ways: # # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will # still reply to client requests, possibly with out of date data, or the # data set may just be empty if this is the first synchronization. # # 2) if slave-serve-stale-data is set to 'no' the slave will reply with # an error "SYNC with master in progress" to all the kind of commands # but to INFO and SLAVEOF. # slave-serve-stale-data yes # You can configure a slave instance to accept writes or not. Writing against # a slave instance may be useful to store some ephemeral data (because data # written on a slave will be easily deleted after resync with the master) but # may also cause problems if clients are writing to it because of a # misconfiguration. # # Since Redis 2.6 by default slaves are read-only. # # Note: read only slaves are not designed to be exposed to untrusted clients # on the internet. It's just a protection layer against misuse of the instance. # Still a read only slave exports by default all the administrative commands # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve # security of read only slaves using 'rename-command' to shadow all the # administrative / dangerous commands. slave-read-only yes # Replication SYNC strategy: disk or socket. # # ------------------------------------------------------- # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY # ------------------------------------------------------- # # New slaves and reconnecting slaves that are not able to continue the replication # process just receiving differences, need to do what is called a "full # synchronization". An RDB file is transmitted from the master to the slaves. # The transmission can happen in two different ways: # # 1) Disk-backed: The Redis master creates a new process that writes the RDB # file on disk. Later the file is transferred by the parent # process to the slaves incrementally. # 2) Diskless: The Redis master creates a new process that directly writes the # RDB file to slave sockets, without touching the disk at all. # # With disk-backed replication, while the RDB file is generated, more slaves # can be queued and served with the RDB file as soon as the current child producing # the RDB file finishes its work. With diskless replication instead once # the transfer starts, new slaves arriving will be queued and a new transfer # will start when the current one terminates. # # When diskless replication is used, the master waits a configurable amount of # time (in seconds) before starting the transfer in the hope that multiple slaves # will arrive and the transfer can be parallelized. # # With slow disks and fast (large bandwidth) networks, diskless replication # works better. repl-diskless-sync no # When diskless replication is enabled, it is possible to configure the delay # the server waits in order to spawn the child that transfers the RDB via socket # to the slaves. # # This is important since once the transfer starts, it is not possible to serve # new slaves arriving, that will be queued for the next RDB transfer, so the server # waits a delay in order to let more slaves arrive. # # The delay is specified in seconds, and by default is 5 seconds. To disable # it entirely just set it to 0 seconds and the transfer will start ASAP. repl-diskless-sync-delay 5 # Slaves send PINGs to server in a predefined interval. It's possible to change # this interval with the repl_ping_slave_period option. The default value is 10 # seconds. # # repl-ping-slave-period 10 # The following option sets the replication timeout for: # # 1) Bulk transfer I/O during SYNC, from the point of view of slave. # 2) Master timeout from the point of view of slaves (data, pings). # 3) Slave timeout from the point of view of masters (REPLCONF ACK pings). # # It is important to make sure that this value is greater than the value # specified for repl-ping-slave-period otherwise a timeout will be detected # every time there is low traffic between the master and the slave. # # repl-timeout 60 # Disable TCP_NODELAY on the slave socket after SYNC? # # If you select "yes" Redis will use a smaller number of TCP packets and # less bandwidth to send data to slaves. But this can add a delay for # the data to appear on the slave side, up to 40 milliseconds with # Linux kernels using a default configuration. # # If you select "no" the delay for data to appear on the slave side will # be reduced but more bandwidth will be used for replication. # # By default we optimize for low latency, but in very high traffic conditions # or when the master and slaves are many hops away, turning this to "yes" may # be a good idea. repl-disable-tcp-nodelay no # Set the replication backlog size. The backlog is a buffer that accumulates # slave data when slaves are disconnected for some time, so that when a slave # wants to reconnect again, often a full resync is not needed, but a partial # resync is enough, just passing the portion of data the slave missed while # disconnected. # # The bigger the replication backlog, the longer the time the slave can be # disconnected and later be able to perform a partial resynchronization. # # The backlog is only allocated once there is at least a slave connected. # # repl-backlog-size 1mb # After a master has no longer connected slaves for some time, the backlog # will be freed. The following option configures the amount of seconds that # need to elapse, starting from the time the last slave disconnected, for # the backlog buffer to be freed. # # A value of 0 means to never release the backlog. # # repl-backlog-ttl 3600 # The slave priority is an integer number published by Redis in the INFO output. # It is used by Redis Sentinel in order to select a slave to promote into a # master if the master is no longer working correctly. # # A slave with a low priority number is considered better for promotion, so # for instance if there are three slaves with priority 10, 100, 25 Sentinel will # pick the one with priority 10, that is the lowest. # # However a special priority of 0 marks the slave as not able to perform the # role of master, so a slave with priority of 0 will never be selected by # Redis Sentinel for promotion. # # By default the priority is 100. slave-priority 100 # It is possible for a master to stop accepting writes if there are less than # N slaves connected, having a lag less or equal than M seconds. # # The N slaves need to be in "online" state. # # The lag in seconds, that must be <= the specified value, is calculated from # the last ping received from the slave, that is usually sent every second. # # This option does not GUARANTEE that N replicas will accept the write, but # will limit the window of exposure for lost writes in case not enough slaves # are available, to the specified number of seconds. # # For example to require at least 3 slaves with a lag <= 10 seconds use: # # min-slaves-to-write 3 # min-slaves-max-lag 10 # # Setting one or the other to 0 disables the feature. # # By default min-slaves-to-write is set to 0 (feature disabled) and # min-slaves-max-lag is set to 10. # A Redis master is able to list the address and port of the attached # slaves in different ways. For example the "INFO replication" section # offers this information, which is used, among other tools, by # Redis Sentinel in order to discover slave instances. # Another place where this info is available is in the output of the # "ROLE" command of a masteer. # # The listed IP and address normally reported by a slave is obtained # in the following way: # # IP: The address is auto detected by checking the peer address # of the socket used by the slave to connect with the master. # # Port: The port is communicated by the slave during the replication # handshake, and is normally the port that the slave is using to # list for connections. # # However when port forwarding or Network Address Translation (NAT) is # used, the slave may be actually reachable via different IP and port # pairs. The following two options can be used by a slave in order to # report to its master a specific set of IP and port, so that both INFO # and ROLE will report those values. # # There is no need to use both the options if you need to override just # the port or the IP address. # # slave-announce-ip 5.5.5.5 # slave-announce-port 1234 ################################## SECURITY ################################### # Require clients to issue AUTH before processing any other # commands.

By default # this limit is set to 10000 clients, however if the Redis server is not # able to configure the process file limit to allow for the specified limit # the max number of allowed clients is set to the current file limit # minus 32 (as Redis reserves a few file descriptors for internal uses). # # Once the limit is reached Redis will close all the new connections sending # an error 'max number of clients reached'. # # maxclients 10000 # Don't use more memory than the specified amount of bytes. # When the memory limit is reached Redis will try to remove keys # according to the eviction policy selected (see maxmemory-policy). # # If Redis can't remove keys according to the policy, or if the policy is # set to 'noeviction', Redis will start to reply with errors to commands # that would use more memory, like SET, LPUSH, and so on, and will continue # to reply to read-only commands like GET. # # This option is usually useful when using Redis as an LRU cache, or to set # a hard memory limit for an instance (using the 'noeviction' policy). # # WARNING: If you have slaves attached to an instance with maxmemory on, # the size of the output buffers needed to feed the slaves are subtracted # from the used memory count, so that network problems / resyncs will # not trigger a loop where keys are evicted, and in turn the output # buffer of slaves is full with DELs of keys evicted triggering the deletion # of more keys, and so forth until the database is completely emptied. # # In short... if you have slaves attached it is suggested that you set a lower # limit for maxmemory so that there is some free RAM on the system for slave # output buffers (but this is not needed if the policy is 'noeviction'). # # maxmemory # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory # is reached. You can select among five behaviors: # # volatile-lru -> remove the key with an expire set using an LRU algorithm # allkeys-lru -> remove any key according to the LRU algorithm # volatile-random -> remove a random key with an expire set # allkeys-random -> remove a random key, any key # volatile-ttl -> remove the key with the nearest expire time (minor TTL) # noeviction -> don't expire at all, just return an error on write operations # # Note: with any of the above policies, Redis will return an error on write # operations, when there are no suitable keys for eviction. # # At the date of writing these commands are: set setnx setex append # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby # getset mset msetnx exec sort # # The default is: # # maxmemory-policy noeviction # LRU and minimal TTL algorithms are not precise algorithms but approximated # algorithms (in order to save memory), so you can tune it for speed or # accuracy. For default Redis will check five keys and pick the one that was # used less recently, you can change the sample size using the following # configuration directive. # # The default of 5 produces good enough results. 10 Approximates very closely # true LRU but costs a bit more CPU. 3 is very fast but not very accurate. # # maxmemory-samples 5 ############################## APPEND ONLY MODE ############################### # By default Redis asynchronously dumps the dataset on disk. This mode is # good enough in many applications, but an issue with the Redis process or # a power outage may result into a few minutes of writes lost (depending on # the configured save points). # # The Append Only File is an alternative persistence mode that provides # much better durability. For instance using the default data fsync policy # (see later in the config file) Redis can lose just one second of writes in a # dramatic event like a server power outage, or a single write if something # wrong with the Redis process itself happens, but the operating system is # still running correctly. # # AOF and RDB persistence can be enabled at the same time without problems. # If the AOF is enabled on startup Redis will load the AOF, that is the file # with the better durability guarantees. # # Please check http://redis.io/topics/persistence for more information. appendonly no # The name of the append only file (default: "appendonly.aof") appendfilename "appendonly.aof" # The fsync() call tells the Operating System to actually write data on disk # instead of waiting for more data in the output buffer. Some OS will really flush # data on disk, some other OS will just try to do it ASAP. # # Redis supports three different modes: # # no: don't fsync, just let the OS flush the data when it wants. Faster. # always: fsync after every write to the append only log. Slow, Safest. # everysec: fsync only one time every second. Compromise. # # The default is "everysec", as that's usually the right compromise between # speed and data safety. It's up to you to understand if you can relax this to # "no" that will let the operating system flush the output buffer when # it wants, for better performances (but if you can live with the idea of # some data loss consider the default persistence mode that's snapshotting), # or on the contrary, use "always" that's very slow but a bit safer than # everysec. # # More details please check the following article: # http://antirez.com/post/redis-persistence-demystified.html # # If unsure, use "everysec". # appendfsync always appendfsync everysec # appendfsync no # When the AOF fsync policy is set to always or everysec, and a background # saving process (a background save or AOF log background rewriting) is # performing a lot of I/O against the disk, in some Linux configurations # Redis may block too long on the fsync() call. Note that there is no fix for # this currently, as even performing fsync in a different thread will block # our synchronous write(2) call. # # In order to mitigate this problem it's possible to use the following option # that will prevent fsync() from being called in the main process while a # BGSAVE or BGREWRITEAOF is in progress. # # This means that while another child is saving, the durability of Redis is # the same as "appendfsync none". In practical terms, this means that it is # possible to lose up to 30 seconds of log in the worst scenario (with the # default Linux settings). # # If you have latency problems turn this to "yes". Otherwise leave it as # "no" that is the safest pick from the point of view of durability. no-appendfsync-on-rewrite no # Automatic rewrite of the append only file. # Redis is able to automatically rewrite the log file implicitly calling # BGREWRITEAOF when the AOF log size grows by the specified percentage. # # This is how it works: Redis remembers the size of the AOF file after the # latest rewrite (if no rewrite has happened since the restart, the size of # the AOF at startup is used). # # This base size is compared to the current size. If the current size is # bigger than the specified percentage, the rewrite is triggered. Also # you need to specify a minimal size for the AOF file to be rewritten, this # is useful to avoid rewriting the AOF file even if the percentage increase # is reached but it is still pretty small. # # Specify a percentage of zero in order to disable the automatic AOF # rewrite feature. auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb # An AOF file may be found to be truncated at the end during the Redis # startup process, when the AOF data gets loaded back into memory. # This may happen when the system where Redis is running # crashes, especially when an ext4 filesystem is mounted without the # data=ordered option (however this can't happen when Redis itself # crashes or aborts but the operating system still works correctly). # # Redis can either exit with an error when this happens, or load as much # data as possible (the default now) and start if the AOF file is found # to be truncated at the end. The following option controls this behavior. # # If aof-load-truncated is set to yes, a truncated AOF file is loaded and # the Redis server starts emitting a log to inform the user of the event. # Otherwise if the option is set to no, the server aborts with an error # and refuses to start. When the option is set to no, the user requires # to fix the AOF file using the "redis-check-aof" utility before to restart # the server. # # Note that if the AOF file will be found to be corrupted in the middle # the server will still exit with an error.

In order to start a Redis instance as a # cluster node enable the cluster support uncommenting the following: # # cluster-enabled yes # Every cluster node has a cluster configuration file. This file is not # intended to be edited by hand. It is created and updated by Redis nodes. # Every Redis Cluster node requires a different cluster configuration file. # Make sure that instances running in the same system do not have # overlapping cluster configuration file names. # # cluster-config-file nodes-6379.conf # Cluster node timeout is the amount of milliseconds a node must be unreachable # for it to be considered in failure state. # Most other internal time limits are multiple of the node timeout. # # cluster-node-timeout 15000 # A slave of a failing master will avoid to start a failover if its data # looks too old. # # There is no simple way for a slave to actually have a exact measure of # its "data age", so the following two checks are performed: # # 1) If there are multiple slaves able to failover, they exchange messages # in order to try to give an advantage to the slave with the best # replication offset (more data from the master processed). # Slaves will try to get their rank by offset, and apply to the start # of the failover a delay proportional to their rank. # # 2) Every single slave computes the time of the last interaction with # its master. This can be the last ping or command received (if the master # is still in the "connected" state), or the time that elapsed since the # disconnection with the master (if the replication link is currently down). # If the last interaction is too old, the slave will not try to failover # at all. # # The point "2" can be tuned by user. Specifically a slave will not perform # the failover if, since the last interaction with the master, the time # elapsed is greater than: # # (node-timeout * slave-validity-factor) + repl-ping-slave-period # # So for example if node-timeout is 30 seconds, and the slave-validity-factor # is 10, and assuming a default repl-ping-slave-period of 10 seconds, the # slave will not try to failover if it was not able to talk with the master # for longer than 310 seconds. # # A large slave-validity-factor may allow slaves with too old data to failover # a master, while a too small value may prevent the cluster from being able to # elect a slave at all. # # For maximum availability, it is possible to set the slave-validity-factor # to a value of 0, which means, that slaves will always try to failover the # master regardless of the last time they interacted with the master. # (However they'll always try to apply a delay proportional to their # offset rank). # # Zero is the only value able to guarantee that when all the partitions heal # the cluster will always be able to continue. # # cluster-slave-validity-factor 10 # Cluster slaves are able to migrate to orphaned masters, that are masters # that are left without working slaves. This improves the cluster ability # to resist to failures as otherwise an orphaned master can't be failed over # in case of failure if it has no working slaves. # # Slaves migrate to orphaned masters only if there are still at least a # given number of other working slaves for their old master. This number # is the "migration barrier". A migration barrier of 1 means that a slave # will migrate only if there is at least 1 other working slave for its master # and so forth. It usually reflects the number of slaves you want for every # master in your cluster. # # Default is 1 (slaves migrate only if their masters remain with at least # one slave). To disable migration just set it to a very large value. # A value of 0 can be set but is useful only for debugging and dangerous # in production. # # cluster-migration-barrier 1 # By default Redis Cluster nodes stop accepting queries if they detect there # is at least an hash slot uncovered (no available node is serving it). # This way if the cluster is partially down (for example a range of hash slots # are no longer covered) all the cluster becomes, eventually, unavailable. # It automatically returns available as soon as all the slots are covered again. # # However sometimes you want the subset of the cluster which is working, # to continue to accept queries for the part of the key space that is still # covered. In order to do so, just set the cluster-require-full-coverage # option to no. # # cluster-require-full-coverage yes # In order to setup your cluster make sure to read the documentation # available at http://redis.io web site. ################################## SLOW LOG ################################### # The Redis Slow Log is a system to log queries that exceeded a specified # execution time. The execution time does not include the I/O operations # like talking with the client, sending the reply and so forth, # but just the time needed to actually execute the command (this is the only # stage of command execution where the thread is blocked and can not serve # other requests in the meantime). # # You can configure the slow log with two parameters: one tells Redis # what is the execution time, in microseconds, to exceed in order for the # command to get logged, and the other parameter is the length of the # slow log. When a new command is logged the oldest one is removed from the # queue of logged commands. # The following time is expressed in microseconds, so 1000000 is equivalent # to one second. Note that a negative number disables the slow log, while # a value of zero forces the logging of every command. slowlog-log-slower-than 10000 # There is no limit to this length.

After this limit is # reached the script is terminated with a SIGKILL and the execution retried. # NOTIFICATION SCRIPT # # sentinel notification-script # # Call the specified notification script for any sentinel event that is # generated in the WARNING level (for instance -sdown, -odown, and so forth). # This script should notify the system administrator via email, SMS, or any # other messaging system, that there is something wrong with the monitored # Redis systems. # # The script is called with just two arguments: the first is the event type # and the second the event description. # # The script must exist and be executable in order for sentinel to start if # this option is provided. # # Example: # # sentinel notification-script mymaster /var/redis/notify.sh # CLIENTS RECONFIGURATION SCRIPT # # sentinel client-reconfig-script # # When the master changed because of a failover a script can be called in # order to perform application-specific tasks to notify the clients that the # configuration has changed and the master is at a different address. # # The following arguments are passed to the script: # # # # is currently always "failover" # is either "leader" or "observer" # # The arguments from-ip, from-port, to-ip, to-port are used to communicate # the old address of the master and the new address of the elected slave # (now a master). # # This script should be resistant to multiple invocations. # # Example: # # sentinel client-reconfig-script mymaster /var/redis/reconfig.sh ================================================ FILE: extern/deprecated/redis-3.2.8/src/.gitignore ================================================ *.gcda *.gcno *.gcov redis.info lcov-html ================================================ FILE: extern/deprecated/redis-3.2.8/src/Makefile ================================================ # Redis Makefile # Copyright (C) 2009 Salvatore Sanfilippo # This file is released under the BSD license, see the COPYING file # # The Makefile composes the final FINAL_CFLAGS and FINAL_LDFLAGS using # what is needed for Redis plus the standard CFLAGS and LDFLAGS passed. # However when building the dependencies (Jemalloc, Lua, Hiredis, ...) # CFLAGS and LDFLAGS are propagated to the dependencies, so to pass # flags only to be used when compiling / linking Redis itself REDIS_CFLAGS # and REDIS_LDFLAGS are used instead (this is the case of 'make gcov'). # # Dependencies are stored in the Makefile.dep file.

This collision resolution code allows nodes to automatically * end with a different configEpoch at startup automatically. * * In all the cases, we want a mechanism that resolves this issue automatically * as a safeguard.
