It manages a set of timeouts that, when expired, invoke a callback. It uses features of C++11 in order to avoid platform specific code. It supports one-shot and periodic timeouts. ## Documentation Please see the documentation in [cpptime.h](./cpptime.h) for more detailed information about the implementation. ## Implementation Status We use this timer implementation in some of our products without issues. Judging from the GitHub stars and forks, it seems to be used in other projects as well. Since it was implemented in 2015 and has not seen many issue reports, we assume it is quite stable. But note that this is not a guarantee and if you find any issues, please report them. ## Use Cases and Limitations Naturally the implementation makes some trade-offs. This makes it useful for some cases, and less so for others. - The timer runs completely in user space. This makes it slightly less efficient than other solutions, such as `timer_create()` or `timerfd_create()`. However, in many cases, this overhead is acceptable. - Given a C++11 capable compiler, the code is portable. - The API to add or remove a timeout is arguably nicer than the platform specific alternatives. E.g. ```cpp timer.add(seconds(2), [](CppTime::timer_id) { ... }); ``` - The implementation is small and easy to understand. You can change or extend it to make it better suitable for your use-cases. ## Examples A one shot timer. ~~~ using namespace std::chrono; CppTime::Timer t; t.add(seconds(2), [](CppTime::timer_id) { std::cout << "yes\n"; }); std::this_thread::sleep_for(seconds(3)); ~~~ A periodic timer that is first executed after 2 seconds, and after this every second. The timeout event is then removed after 10 seconds. When a timeout event is removed, its attached handler is also freed to clean-up any attached resources. ~~~ using namespace std::chrono; CppTime::Timer t; auto id = t.add(seconds(2), [](CppTime::timer_id) { std::cout << "yes\n"; }, seconds(1)); std::this_thread::sleep_for(seconds(10)); t.remove(id); ~~~ See the tests for more examples. ## Usage To use the timer component, Simply copy [cpptime.h](./cpptime.h) into you project. Everything is contained in this single header file. Tests can be compiled and executed with the following commands, assuming you are on a POSIX machine. ~~~ g++ -std=c++11 -Wall -Wextra -o test tests/timer_test.cpp -l pthread ./test ~~~ ## Possible Features While the current implementation serves us well, there are some features that might potentially be interesting for other use cases. Contact us in case you are interested. - [x] Ability to have multiple timer components running. - [x] Distribute it as a header only library. - [ ] Optionally avoid locking. - [ ] API to use client thread instead of creating its own. - [ ] API to use client mutex instead of its own. ## Known issues GCC up to version 10 (e.g. used in Ubuntu 20.04 LTS) has [an issue][gcc-clock] where `conditional_variable` doesn't use the monotonic clock. This leads to unreliable programs when the system clock is moved backwards. See #5 for more details. The fix is to update to a GCC version with the fix applied, e.g. version 10 or greater.

It is implemented in * pure C++11. It is therefore very portable given a compliant compiler. * * A timeout can be added with one of the `add()` functions, and removed with * the `remove()` function. A timeout can be set to be either one-shot or * periodic. If it is one-shot, the callback is invoked once and the timeout * event is then automatically removed. If the timeout is periodic, it is * always renewed and never automatically removed. * * When a timeout is removed or when a one-shot timeout expires, the handler * will be deleted to clean-up any resources. * * Removing a timeout is possible from within the callback. In this case, you * must be careful not to access any captured variables, if any, after calling * `remove()`, because they are no longer valid. * * Timeout Units * ------------- * * The preferred functions for adding timeouts are those that take a * `std::chrono::...` argument. However, for convenience, there is also an API * that takes a uint64_t. When using this API, all values are expected to be * given in microseconds (us). * * For periodic timeouts, a separate timeout can be specified for the initial * (first) timeout, and the periodicity after that. * * To avoid drifts, times are added by simply adding the period to the initially * calculated (or provided) time. Also, we use `wait until` type of API to wait * for a timeout instead of a `wait for` API. * * Data Structure * -------------- * * Internally, a std::vector is used to store timeout events. The timer_id * returned from the `add` functions are used as index to this vector. * * In addition, a std::multiset is used that holds all time points when * timeouts expire. * * Using a vector to store timeout events has some implications. It is very * fast to remove an event, because the timer_id is the vector's index. On the * other hand, this makes it also more complicated to manage the timer_ids. The * current solution is to keep track of ids that are freed in order to re-use * them. A stack is used for this. * * Examples * -------- * * More examples can be found in the `tests` folder. * * ~~~ * CppTime::Timer t; * t.add(std::chrono::seconds(1), [](CppTime::timer_id){ std::cout << "got it!"; }); * std::this_thread::sleep_for(std::chrono::seconds(2)); * ~~~ */ // Includes #include #include #include #include #include #include #include #include #include namespace CppTime { // Public types using timer_id = std::size_t; using handler_t = std::function; using clock = std::chrono::steady_clock; using timestamp = std::chrono::time_point; using duration = std::chrono::microseconds; // Private definitions.
