v0.6.1

• Add extfs in the fs module

This allows you to operate a disk file filled with ext4 filesystem from user space.

To enable this feature, you should set ENABLE_EXTFS when building with CMake. Package e2fsprogs is also required.

v0.6.0

Version 0.6 is released. New features are:

• Now Photon is able to run on DPDK when enabling the FSTACK_DPDK IO engine. F-Stack is an open-source project from Tencent. It has ported the entire FreeBSD network stack on top of DPDK, and provided userspace sockets and events API. We have integrated Photon's coroutine scheduler with F-Stack, and made a busy-polling program more friendly to DPDK developers than ever before. In terms of performance, the network app has seen the improvement of 20% ~ 40%, compared with the Linux kernel based on interrupt.
• io_uring added support of send_zc and register_files
• RPC added support of complicated user-defined types and map
• Datagram based socket, supports UDP and DomainSocket

v0.5.7

• Fix a compiling issue in aarch64 when gcc version < 8

v0.5.6

• alog use localtime

v0.5.5

• alog with throttler (like the glog interface)
• zerocopy socket minor fix
• io_uring fixed_file flag

v0.5.4

• New behavior of photon::init()
• io_uring engine introduced register_files and IORING_SETUP_COOP_TASKRUN
• http fixed a tiny bug

v0.5.3

v0.5.3 fixed some compiling issues on macOS. And a new macOS CI workflow is added.

v0.5.2

• Fix a thread-pool hang bug

v0.5.1

• Some bug fixes for HTTP module

v0.5.0

v0.5 has come! The changes are:

• New http server. We have completely removed boost dependency from Photon.
• Asymmetric spinlock, different lock routine in foreground condition and background, brings better performance for foreground lock situation.
• New context switch implemention, using inline assembly code clobbers to store and reload status registers during context switch.
• Photon thread atomic run queue using asymmetric spinlock, less time spent on acquiring lock during scheduling.
