New submission from Martin Panter: Normally there is a Python 3 compatibility warning emitted when a class is based on object, implements __eq__(), but does not define __hash__():
$ python -3 -c 'class C(object): __eq__ = lambda self, other: True' -c:1: DeprecationWarning: Overriding __eq__ blocks inheritance of __hash__ in 3.x But when warnings are raised as exceptions, this warning seems to be suppressed: $ python -3 -Werror -c 'class C(object): __eq__ = lambda self, other: True' Perhaps there is bad exception handling at the warn() call site. ---------- messages: 284539 nosy: martin.panter priority: normal severity: normal stage: needs patch status: open title: No __hash__() inheritance warning with -Werror type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29138> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
