我有一个使用线程的 python 瓶应用程序。由于我使用的是monkey.patch,线程正在阻止应用程序执行(从线程触发的对话框正在阻止瓶子路由响应客户端,直到被解散。)
这里的一个小研究表明我应该使用猴子补丁而不尝试修补线程:
# Patch python's threads with greenlets
from gevent import monkey
monkey.patch_all(thread=False)
这不会阻止我写的一个最小的例子。
但是在密集使用线程时会引发这些错误,方法如下threading.setEvent()
:这是我得到的错误:

这是 gevent.monkeypatch 的已知问题吗?有任何想法吗?
