Question

我在使用PyDev 3.9.2下的PyDev调试器附加基于gevent的进程时遇到问题。

它在PyDev 3.9.1和LiClipse 3.9.1中运行良好，而不是3.9.2这是最新的PyDev（2015年2月6日）。

当一段代码直接从PyDev的调试器运行而不是从外部运行时，它也能正常工作。

请注意，它并不取决于是否设置了断点（启用与否） - 附加到流程的事实足以引发异常。

这是一个重现行为的示例模块以及两个例外 - 一个来自PyDev，另一个来自gevent代码的观点。

任何人都可以对此有所了解吗？非常感谢。

from gevent.monkey import patch_all
patch_all()

import threading
import gevent

def myfunc():
    t = threading.current_thread()
    print(t.name)

while True:
    gevent.spawn(myfunc)
    gevent.sleep(1)
