New submission from etuardu <edonan@gmail.com>: The definition of daemon thread in the current documentation reads: «A thread can be flagged as a "daemon thread". The significance of this flag is that the entire Python program exits when only daemon threads are left. [...]» (http://docs.python.org/library/threading.html#thread-objects) I think it's not very clear from this that daemon threads themselves terminate when the program (main thread plus other non-daemon threads) terminates. I think this have to be said more explicitly. I'd propose a change with something like: «A thread can be flagged as a "daemon thread", which means it will get shut down when the overall program terminates. The entire Python program exits when only daemon threads are left.» ---------- assignee: docs@python components: Documentation messages: 144691 nosy: docs@python, etuardu priority: normal severity: normal status: open title: Unclear behavior of daemon threads on main thread exit type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue13077> _______________________________________
