New submission from Marco Dickert <ma...@misterunknown.de>:
I guess I found a bug in the documented Queue.join() example [1]. The problem is the break condition for the while loop of the worker. If the item is None, the loop breaks, but the worker never calls item.task_done(). Thus the q.join() statement never returns, because the last task (None) remains unfinished. This should solve the issue: ``` if item is None: item.task_done() break ``` [1] https://docs.python.org/3/library/queue.html#queue.Queue.join ---------- assignee: docs@python components: Documentation messages: 347310 nosy: docs@python, misterunknown priority: normal severity: normal status: open title: Queue.join(): Broken example in documentation versions: Python 3.5, Python 3.6, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37503> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
