# CocoaAsyncSocket
[](https://travis-ci.org/robbiehanson/CocoaAsyncSocket) [](http://cocoadocs.org/docsets/CocoaAsyncSocket) [](https://github.com/Carthage/Carthage) [](http://cocoapods.org/?q=CocoaAsyncSocket) [](https://en.wikipedia.org/wiki/Public_domain)
CocoaAsyncSocket provides easy-to-use and powerful asynchronous socket libraries for macOS, iOS, and tvOS. The classes are described below.
## Installation
#### CocoaPods
Install using [CocoaPods](https://cocoapods.org) by adding this line to your Podfile:
````ruby
use_frameworks! # Add this if you are targeting iOS 8+ or using Swift
pod 'CocoaAsyncSocket'
````
#### Carthage
CocoaAsyncSocket is [Carthage](https://github.com/Carthage/Carthage) compatible. To include it add the following line to your `Cartfile`
```bash
github "robbiehanson/CocoaAsyncSocket" "master"
```
The project is currently configured to build for **iOS**, **tvOS** and **Mac**. After building with carthage the resultant frameworks will be stored in:
* `Carthage/Build/iOS/CocoaAsyncSocket.framework`
* `Carthage/Build/tvOS/CocoaAsyncSocket.framework`
* `Carthage/Build/Mac/CocoaAsyncSocket.framework`
Select the correct framework(s) and drag it into your project.
#### Swift Package Manager
Simply add the package dependency to your Package.swift and depend on "CocoaAsyncSocket" in the necessary targets:
```swift
dependencies: [
.package(url: "https://github.com/robbiehanson/CocoaAsyncSocket", from: "7.6.4")
]
```
#### Manual
You can also include it into your project by adding the source files directly, but you should probably be using a dependency manager to keep up to date.
### Importing
Using Objective-C:
```obj-c
// When using Clang Modules:
@import CocoaAsyncSocket;
// or when not:
#import "GCDAsyncSocket.h" // for TCP
#import "GCDAsyncUdpSocket.h" // for UDP
```
Using Swift:
```swift
import CocoaAsyncSocket
```
## TCP
**GCDAsyncSocket** is a TCP/IP socket networking library built atop Grand Central Dispatch. Here are the key features available:
- Native Objective-C, fully self-contained in one class.<br/>
_No need to muck around with sockets or streams. This class handles everything for you._
- Full delegate support<br/>
_Errors, connections, read completions, write completions, progress, and disconnections all result in a call to your delegate method._
- Queued non-blocking reads and writes, with optional timeouts.<br/>
_You tell it what to read or write, and it handles everything for you. Queueing, buffering, and searching for termination sequences within the stream - all handled for you automatically._
- Automatic socket acceptance.<br/>
_Spin up a server socket, tell it to accept connections, and it will call you with new instances of itself for each connection._
- Support for TCP streams over IPv4 and IPv6.<br/>
_Automatically connect to IPv4 or IPv6 hosts. Automatically accept incoming connections over both IPv4 and IPv6 with a single instance of this class. No more worrying about multiple sockets._
- Support for TLS / SSL<br/>
_Secure your socket with ease using just a single method call. Available for both client and server sockets._
- Fully GCD based and Thread-Safe<br/>
_It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. Further, the delegate methods are all invoked asynchronously onto a dispatch_queue of your choosing. This means parallel operation of your socket code, and your delegate/processing code._
## UDP
**GCDAsyncUdpSocket** is a UDP/IP socket networking library built atop Grand Central Dispatch. Here are the key features available:
- Native Objective-C, fully self-contained in one class.<br/>
_No need to muck around with low-level sockets. This class handles everything for you._
- Full delegate support.<br/>
_Errors, send completions, receive completions, and disconnections all result in a call to your delegate method._
- Queued non-blocking send and receive operations, with optional timeouts.<br/>
_You tell it what to send or receive, and it handles everything for you. Queueing, buffering, waiting and checking errno - all handled for you automatically._
- Support for IPv4 and IPv6.<br/>
_Automatically send/recv using IPv4 and/or IPv6. No more worrying about multiple sockets._
- Fully GCD based and Thread-Safe<br/>
_It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. Further, the delegate methods are all invoked asynchronously onto a dispatch_queue of your choosing. This means parallel operation of your socket code, and your delegate/processing code._
***
For those new(ish) to networking, it's recommended you **[read the wiki](https://github.com/robbiehanson/CocoaAsyncSocket/wiki)**.<br/>_Sockets might not work exactly like you think they do..._
**Still got questions?** Try the **[CocoaAsyncSocket Mailing List](https://groups.google.com/group/cocoaasyncsocket)**.

* If you set this to YES, then the underlying SecureTransport system will not evaluate the SecTrustRef of the peer.
* Instead it will pause at the moment evaulation would typically occur,
* and allow us to handle the security evaluation however we see fit.
* So GCDAsyncSocket will invoke the delegate method socket:shouldTrustPeer: passing the SecTrustRef.
*
* Note that if you set this option, then all other configuration keys are ignored.
* Evaluation will be completely up to you during the socket:didReceiveTrust:completionHandler: delegate method.
*
* For more information on trust evaluation see:
* Apple's Technical Note TN2232 - HTTPS Server Trust Evaluation
* https://developer.apple.com/library/ios/technotes/tn2232/_index.html
*
* If unspecified, the default value is NO.
*
* - GCDAsyncSocketUseCFStreamForTLS (iOS only)
* The value must be of type NSNumber, encapsulating a BOOL value.
* By default GCDAsyncSocket will use the SecureTransport layer to perform encryption.
* This gives us more control over the security protocol (many more configuration options),
* plus it allows us to optimize things like sys calls and buffer allocation.
*
* However, if you absolutely must, you can instruct GCDAsyncSocket to use the old-fashioned encryption
* technique by going through the CFStream instead. So instead of using SecureTransport, GCDAsyncSocket
* will instead setup a CFRead/CFWriteStream. And then set the kCFStreamPropertySSLSettings property
* (via CFReadStreamSetProperty / CFWriteStreamSetProperty) and will pass the given options to this method.
*
* Thus all the other keys in the given dictionary will be ignored by GCDAsyncSocket,
* and will passed directly CFReadStreamSetProperty / CFWriteStreamSetProperty.
* For more infomation on these keys, please see the documentation for kCFStreamPropertySSLSettings.
*
* If unspecified, the default value is NO.
*
* ==== The available CONFIGURATION KEYS are:
*
* - kCFStreamSSLPeerName
* The value must be of type NSString.
* It should match the name in the X.509 certificate given by the remote party.
* See Apple's documentation for SSLSetPeerDomainName.
*
* - kCFStreamSSLCertificates
* The value must be of type NSArray.
* See Apple's documentation for SSLSetCertificate.
*
* - kCFStreamSSLIsServer

* See Apple's documentation for SSLCreateContext for iOS.
* This is optional for iOS. If not supplied, a NO value is the default.
* This is not needed for Mac OS X, and the value is ignored.
*
* - GCDAsyncSocketSSLPeerID
* The value must be of type NSData.
* You must set this value if you want to use TLS session resumption.
* See Apple's documentation for SSLSetPeerID.
*
* - GCDAsyncSocketSSLProtocolVersionMin

*
* Please refer to Apple's documentation for corresponding SSLFunctions.
*
* If you pass in nil or an empty dictionary, the default settings will be used.
*
* IMPORTANT SECURITY NOTE:
* The default settings will check to make sure the remote party's certificate is signed by a
* trusted 3rd party certificate agency (e.g. verisign) and that the certificate is not expired.
* However it will not verify the name on the certificate unless you
* give it a name to verify against via the kCFStreamSSLPeerName key.
* The security implications of this are important to understand.
* Imagine you are attempting to create a secure connection to MySecureServer.com,
* but your socket gets directed to MaliciousServer.com because of a hacked DNS server.
* If you simply use the default settings, and MaliciousServer.com has a valid certificate,
* the default settings will not detect any problems since the certificate is valid.
* To properly secure your connection in this particular scenario you
* should set the kCFStreamSSLPeerName property to "MySecureServer.com".

/**
* Traditionally sockets are not closed until the conversation is over.
* However, it is technically possible for the remote enpoint to close its write stream.
* Our socket would then be notified that there is no more data to be read,
* but our socket would still be writeable and the remote endpoint could continue to receive our data.
*
* The argument for this confusing functionality stems from the idea that a client could shut down its
* write stream after sending a request to the server, thus notifying the server there are to be no further requests.
* In practice, however, this technique did little to help server developers.
*
* To make matters worse, from a TCP perspective there is no way to tell the difference from a read stream close
* and a full socket close. They both result in the TCP stack receiving a FIN packet. The only way to tell
* is by continuing to write to the socket. If it was only a read stream close, then writes will continue to work.
* Otherwise an error will be occur shortly (when the remote end sends us a RST packet).
*
* In addition to the technical challenges and confusion, many high level socket/stream API's provide
* no support for dealing with the problem. If the read stream is closed, the API immediately declares the
* socket to be closed, and shuts down the write stream as well. In fact, this is what Apple's CFStream API does.
* It might sound like poor design at first, but in fact it simplifies development.
*
* The vast majority of the time if the read stream is closed it's because the remote endpoint closed its socket.
* Thus it actually makes sense to close the socket at this point.
* And in fact this is what most networking developers want and expect to happen.
* However, if you are writing a server that interacts with a plethora of clients,
* you might encounter a client that uses the discouraged technique of shutting down its write stream.
* If this is the case, you can set this property to NO,
* and make use of the socketDidCloseReadStream delegate method.
*
* The default value is YES.

/**
* GCDAsyncSocket maintains thread safety by using an internal serial dispatch_queue.
* In most cases, the instance creates this queue itself.
* However, to allow for maximum flexibility, the internal queue may be passed in the init method.
* This allows for some advanced options such as controlling socket priority via target queues.
* However, when one begins to use target queues like this, they open the door to some specific deadlock issues.
*
* For example, imagine there are 2 queues:
* dispatch_queue_t socketQueue;
* dispatch_queue_t socketTargetQueue;
*
* If you do this (pseudo-code):
* socketQueue.targetQueue = socketTargetQueue;
*
* Then all socketQueue operations will actually get run on the given socketTargetQueue.
* This is fine and works great in most situations.
* But if you run code directly from within the socketTargetQueue that accesses the socket,
* you could potentially get deadlock. Imagine the following code:
*
* - (BOOL)socketHasSomething
* {
* __block BOOL result = NO;
* dispatch_block_t block = ^{
* result = [self someInternalMethodToBeRunOnlyOnSocketQueue];
* }
* if (is_executing_on_queue(socketQueue))
* block();
* else
* dispatch_sync(socketQueue, block);
*
* return result;
* }
*
* What happens if you call this method from the socketTargetQueue? The result is deadlock.
* This is because the GCD API offers no mechanism to discover a queue's targetQueue.
* Thus we have no idea if our socketQueue is configured with a targetQueue.
* If we had this information, we could easily avoid deadlock.
* But, since these API's are missing or unfeasible, you'll have to explicitly set it.
*
* IF you pass a socketQueue via the init method,
* AND you've configured the passed socketQueue with a targetQueue,
* THEN you should pass the end queue in the target hierarchy.
*
* For example, consider the following queue hierarchy:
* socketQueue -> ipQueue -> moduleQueue
*
* This example demonstrates priority shaping within some server.
* All incoming client connections from the same IP address are executed on the same target queue.
* And all connections for a particular module are executed on the same target queue.
* Thus, the priority of all networking for the entire module can be changed on the fly.
* Additionally, networking traffic from a single IP cannot monopolize the module.
*
* Here's how you would accomplish something like that:
* - (dispatch_queue_t)newSocketQueueForConnectionFromAddress:(NSData *)address onSocket:(GCDAsyncSocket *)sock
* {
* dispatch_queue_t socketQueue = dispatch_queue_create("", NULL);
* dispatch_queue_t ipQueue = [self ipQueueForAddress:address];
*
* dispatch_set_target_queue(socketQueue, ipQueue);
* dispatch_set_target_queue(iqQueue, moduleQueue);
*
* return socketQueue;
* }
* - (void)socket:(GCDAsyncSocket *)sock didAcceptNewSocket:(GCDAsyncSocket *)newSocket
* {
* [clientConnections addObject:newSocket];
* [newSocket markSocketQueueTargetQueue:moduleQueue];
* }
*
* Note: This workaround is ONLY needed if you intend to execute code directly on the ipQueue or moduleQueue.
* This is often NOT the case, as such queues are used solely for execution shaping.

* It's not thread-safe to access certain variables from outside the socket's internal queue.

* File descriptors are simply integers which reference an index in the per-process file table.
* However, when one requests a new file descriptor (by opening a file or socket),
* the file descriptor returned is guaranteed to be the lowest numbered unused descriptor.
* So if we're not careful, the following could be possible:
*
* - Thread A invokes a method which returns the socket's file descriptor.
* - The socket is closed via the socket's internal queue on thread B.
* - Thread C opens a file, and subsequently receives the file descriptor that was previously the socket's FD.
* - Thread A is now accessing/altering the file instead of the socket.
*
* In addition to this, other variables are not actually objects,

// 4. Possibly copying overflow into prebuffer (malloc/realloc, memcpy)

// Reading into prebuffer first:
// 1. Possibly resizing prebuffer (malloc/realloc)
// 2. Filling buffer (read)
// 3. Searching for term (memcmp)
// 4. Copying underflow into packet buffer (malloc/realloc, memcpy)
// 5. Removing underflow from prebuffer (memmove)
//
// Comparing the performance of the two we can see that reading
// data into the prebuffer first is slower due to the extra memove.
//
// However:
// The implementation of NSMutableData is open source via core foundation's CFMutableData.
// Decreasing the length of a mutable data object doesn't cause a realloc.
// In other words, the capacity of a mutable data object can grow, but doesn't shrink.
//
// This means the prebuffer will rarely need a realloc.
// The packet buffer, on the other hand, may often need a realloc.
// This is especially true if we are the buffer owner.
// Furthermore, if we are constantly realloc'ing the packet buffer,
// and then moving the overflow into the prebuffer,
// then we're consistently over-allocating memory for each term read.
// And now we get into a bit of a tradeoff between speed and memory utilization.
//
// The end result is that the two perform very similarly.
// And we can answer the original question very simply by another means.
