我有一个 python Bottle 应用程序,它使用线程。由于我正在使用猴子补丁 http://www.gevent.org/gevent.monkey.html,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,直到被关闭。)
这里的一些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)
这不会阻止最小example https://stackoverflow.com/questions/16505586/python-win32api-blocking-bottle-routes我写。
但在大量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?
