用timerfd实现非阻塞的sleep()/usleep()/nanosleep() #30

Open

yueshuaijie wants to merge 2 commits into douban:master from yueshuaijie:patch_sleep

yueshuaijie commented Dec 17, 2024

我用到的一个c库除了网络IO block，还有sleep()等其他block，所以我fork了greenify来实现非阻塞的sleep。原理是把常用的sleep()函数替换为timerfd，加入事件循环，监听read()。
（未解决信号中断sleep的问题）

用法：patch_lib()增加了个默认参数：patch_sleep=False，默认不patch sleep()
如需patch：
greenify.patch_lib('/usr/lib/libmemcached.so', patch_sleep=True)
