STINNER Victor <vstin...@python.org> added the comment:
Thomas Moreau: "One solution would be to use the `self._shutdown_lock` from the executor to protect the call to `close` in `terminate_broken` and the call to `self._thread_wakeup.wakeup` in `shutdown`. That way, the lock is only acquired at critical points without being used all the time. This could also be done by adding `lock=True/False` to only lock the potentially dangerous calls." I wrote a conservative PR 19760 which always lock ProcessPoolExecutor._shutdown_lock while accessing _ThreadWakeup. PR 19760 fix test_killed_child(): it doesn't fail anymore, even with my msg367463 patch (add sleep). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39995> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
