What's New

We present an article to illustrate the theory of Photon's coroutine. Stackful Coroutine Made Fast
Version 0.8 has been released in August 2024

Since 0.7, Photon will use release branches to enhance the reliability of software delivery. Bugfix will be merged into a stable release at first, then to higher release versions, and finally main.
Since version 0.6, Photon can run with a userspace TCP/IP stack on top of DPDK. En / 中文.

Version 0.5 is released. Except for various performance improvements, including spinlock, context switch, and new run queue for coroutine scheduling, we have re-implemented the HTTP module so that there is no boost dependency anymore.
Version 0.4 has come, bringing us these three major features:
1. Support coroutine local variables. Similar to the C++11 thread_local keyword. See doc.
2. Support running on macOS platform, both Intel x86_64 and Apple M1 included.
3. Support LLVM Clang/Apple Clang/GCC compilers.
Photon 0.3 was released on 2 Sep 2022. Except for bug fixes and improvements, a new photon_std namespace is added. Developers can search for std::thread, std::mutex in their own projects, and replace them all into the equivalents of photon_std::<xxx>. It's a quick way to transform thread-based programs to coroutine-based ones.
Photon 0.2 was released on 28 Jul 2022. This release was mainly focused on network socket, security context and multi-vcpu support. We re-worked the WorkPool so it's more friendly now to write multi-vcpu programs.
Made the first tag on 27 Jul 2022. Fix the compatibility for ARM CPU. Throughly compared the TCP echo server performance with other libs.
