Concurrency for Icicle
True concurrency using native threading and multiprocessing for parallelizing code, without blocking.
This library is a component for Icicle that provides native threading, multiprocessing, process synchronization, shared memory, and task workers. Like other Icicle components, this library uses Coroutines built from Awaitables and Generators to make writing asynchronous code more like writing synchronous code.
This library provides a means of parallelizing code without littering your application with complicated lock checking and inter-process communication.
To be as flexible as possible, this library comes with a collection of non-blocking concurrency tools that can be used independently as needed, as well as an "opinionated" worker API that allows you to assign units of work to a pool of worker threads or processes.
Documentation and Support
Requirements
- PHP 5.5+ for v0.3.x branch (current stable) and v1.x branch (mirrors current stable)
- PHP 7 for v2.0 (master) branch supporting generator delegation and return expressions
Suggested
- pthreads extension: Best extension option for concurrency in PHP, but it requires PHP to be compiled with
--enable-maintainer-zts
to enable thread-safety. - pcntl extension: Enables forking concurrency method.
- sysvmsg extension: Required for sharing memory between forks or processes.

Development and Contributing
Interested in contributing to Icicle? Please see our contributing guidelines in the Icicle repository.
Want to hack on the source? A Vagrant box is provided with the repository to give a common development environment for running concurrent threads and processes, and comes with a bunch of handy tools and scripts for testing and experimentation.
Starting up and logging into the virtual machine is as simple as
vagrant up && vagrant ssh
Once inside the VM, you can install PHP extensions with Pickle, switch versions with newphp VERSION
, and test for memory leaks with Valgrind.
