New submission from Vlastimil Zíma: Sentinels lose their identity when they are pickled, meaning they are no longer equal to sentinel with the same name.
>>> from mock import sentinel >>> import pickle >>> sentinel.foo == sentinel.foo True >>> pickle.loads(pickle.dumps(sentinel.foo)) == sentinel.foo False I found this bug using Python 2.7.3 and python-mock 1.0.1. Since mock 1.0 is part of Python 3.3 and 3.4 it affects these versions (tested in 3.3.3). This behavior is tricky to find out if encountered in tests and sentinels can not be used in tests of code which uses pickle and possibly other serializations. ---------- components: Tests messages: 212417 nosy: Vlastimil.Zíma priority: normal severity: normal status: open title: Sentinels identity lost when pickled (unittest.mock) type: behavior versions: Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20804> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
