STINNER Victor added the comment: Running "runtests.py test_cancel_post_init test_shell" and "runtests.py test_wait_for_handle test_wait_for_handle_cancel" of Tulip show a different behaviour of _WaitHandleFuture. In one case, the cancelled wait is still signaled, on other case, it's never signaled.
Currently, a cancelled _WaitHandleFuture always unregisters the overlapped operation, which causes unexpected event or may lead tests to hang. Never unregisters causes a different issue. Unregistering the overlapped indirectly delete it in memory, which is bad if the completion is still signaled. A workaround is to keep a reference to the unregistered overlopped, but it's an ugly workaround. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23095> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
