Re: [I] bthread在持有了pthread的锁之后，如果遇到bthread_sleep的调用，是否会切换工作线程？？ (brpc)
weingithub commented on issue #2456: URL: https://github.com/apache/brpc/issues/2456#issuecomment-1824251933 > 大概率会。因为调用bthread_sleep时，bthread会被挂起，等时间到了，会随机选择一个worker线程来调度该bthread，这时候可能已经切换了worker线程了。 所以，使用bthread时，不能在pthread锁临界区内执行会挂起bthread的操作（bthread_mutex、rpc、bthread_usleep等）。否则，会导致死锁或者其他未定义行为。 非常感谢你的回答，我看https://www.iquanku.com/read/brpc-0.9.7-zh/adb9e61c135a61a7.md这个链接里面的描述的话，好像是如果在bthread中调用pthread_mutex_lock的话，如果是等待拿锁，那么这个时候，bthread是不会切换工作线程的。不知道是不是可以这么理解？  还有个就是，brpc为什么也会导致bthread协程切换？ -- This is an automated message from the Apache Git Service.
