New submission from ProgVal: In Python 3.3, multiprocessing.Process.join() is not blocking with floats lower than 1.0 (not included). It works as expected (ie. blocking for the specified timeout) in Python 2.6->3.2
As you can see in this example, calling join() with 0.99 returns immediately. $ python3.3 Python 3.3.1 (default, Apr 6 2013, 13:58:40) [GCC 4.7.2] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import time >>> import multiprocessing >>> def foo(): ... time.sleep(1000) ... >>> p = multiprocessing.Process(target=foo) >>> p.start() >>> bar = time.time(); p.join(0.99); print(time.time()-bar) 0.015963315963745117 >>> p.is_alive() True >>> bar = time.time(); p.join(1.0); print(time.time()-bar) 1.0011239051818848 >>> p.is_alive() True ---------- components: Library (Lib) messages: 187916 nosy: Valentin.Lorentz priority: normal severity: normal status: open title: multiprocessing.Process.join does not block if timeout is lower than 1 type: behavior versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17856> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
