[issue23293] [Windows] asyncio: race condition related in IocpProactor.connect_pipe()
New submission from STINNER Victor: Currently, IocpProactor.connect_pipe() is implemented with QueueUserWorkItem() which starts a thread that cannot be interrupted. Because of that, this function requires special cases in _register() and close() methods of IocpProactor. While fixing the issue #23095, I saw that IocpProactor.connect_pipe() causes GetQueuedCompletionStatus() returned an unexpected event messages to be logged, but also to hang the test suite. I propose a solution to reimplement IocpProactor.connect_pipe() without a thread: https://code.google.com/p/tulip/issues/detail?id=197 It should fix this issue. -- components: Windows, asyncio messages: 234448 nosy: gvanrossum, haypo, steve.dower, tim.golden, yselivanov, zach.ware priority: normal severity: normal status: open title: [Windows] asyncio: race condition related in IocpProactor.connect_pipe() versions: Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23293 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
