Julien added the comment: `daemon` flag cannot be changed after thread is started, the documentation is right and the code of the daemon setter is actually:
if self._started.is_set(): raise RuntimeError("cannot set daemon status of active thread") But still it looks like a code review problem: all your daemonic threads should be created as daemonic. Breaking the `daemon` semantics looks like a bug magnet: any future uses of non-daemonic threads (by an "experienced" developer of your team, specifically needing a non-daemon thread for a specific task) will behave as a deamon thread and the specific task may not be correctly executed (like, logging an exception?). ---------- nosy: +sizeof _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10444> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
