Mark Dickinson added the comment: To clarify, here's the bug: the following code should raise an exception, but doesn't:
iwasawa:cpython mdickinson$ ./python.exe -3 Python 2.7.3+ (2.7:333fe4c4897a, Nov 17 2012, 18:01:00) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import warnings; warnings.filterwarnings("error") >>> class A(object): ... def __eq__(self, other): ... return False ... Without "warnings.filterwarnings("error")", the warning gets issued as expected: iwasawa:cpython mdickinson$ ./python.exe -3 Python 2.7.3+ (2.7:333fe4c4897a, Nov 17 2012, 18:01:00) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> class A(object): ... def __eq__(self, object): ... return False ... __main__:1: DeprecationWarning: Overriding __eq__ blocks inheritance of __hash__ in 3.x Brett, is it okay to re-open this? Perhaps a change of title would help? Or I can open a new issue for the remaining problem, if you think that's better. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8627> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
