> 【那个bthread用std::mutex导致死锁的问题】请问这个是什么问题，现有的 issue 上也没有搜到 https://github.com/apache/incubator-brpc/blob/master/docs/cn/bthread.md “但这个机制更多是为了规避在一些极端情况下的死锁, 比如所有的用户代码都lock在一个pthread mutex上, 并且这个mutex需要在某个RPC回调中unlock, 如果所有的worker都被阻塞, 那么就没有线程来处理RPC回调了, 整个程序就死锁了. 虽然绝大部分的RPC实现都有这个潜在问题, 但实际出现频率似乎很低, 只要养成不在锁内做RPC的好习惯, 这是完全可以规避的.” ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
