Libcask can help simplify the complex in async non-block network programs.It can easily create millions tasks concurrently, coder can simply use syncblock style to build the application, libcask will help convert this codeimplicitly into Reactor mode of network program.

For legacy 3rd-party libraries, libcask can hook them into async flows withoutchange codes or re-build libraries.

• Round robin scheduling coroutines (not support work-steal)
• Hook socket IO syscalls and related glibc APIs
• Coroutine-level sync primitives among multiple-threads: mutex, spinlock, barrier, condition variant, Semaphore
• Async task for unhookable blocked syscalls

Platform:

• Linux only (ubuntu 16.04 TLS and redhat 7.1 or above recommended)
• gcc version >= 6.2.0

Build library:

$ cd libcask  $ mkdir output  $ bash build.sh

then libcask.so would be present in libcask/output

Build tests:

$ cd libcask/test    $ bash build_test.sh server [debug]

• [] co_rwlock
• [] multiple-thread scheduling with work-steal (not consider to implement)
• hook getaddrinfo
• hook __poll poll select

libco &libgo &libtask inspired this C style coroutine library.
