New submission from dmitry-bychkov <iamdbych...@gmail.com>:
Hello! If you use multiprocessing logger with logging.handlers.QueueHandler it will deadlock on first attempt at logging. First attempt will initialize queue's background thread, which uses multiprocessing logger itself which will result in something what looks like deadlock :) There are workarounds and I'm not sure if it can be classified as a bug, prehaps a little note in documentation about this behaviour will do? I've attached example script. ---------- files: logger_deadlock.py messages: 409088 nosy: iamdbychkov priority: normal severity: normal status: open title: multiprocessing logger deadlocks if used with logging.handlers.QueueHandler versions: Python 3.9 Added file: https://bugs.python.org/file50513/logger_deadlock.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46163> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
