Antoine Pitrou added the comment: As a matter of fact, the bug is in Condition (which is used by Event.wait() but not by Event.is_set(), hence your workaround). Here is a reproducer script.
This looks like a hard issue to solve. There is no way to know whether a process that used to be waiting for a Condition was killed. ---------- title: Multiprocessing: Event.set() blocks indefinitely if a process waiting on it has died. -> multiprocessing.Condition.notify_all() blocks indefinitely if a process waiting on it has died Added file: http://bugs.python.org/file47027/WaitersSleepers.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30975> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
