[Touch-packages] [Bug 1556927] Re: python3 builtin help() fails with exception
so fixed at least in 16.04 LTS and newer releases ** Changed in: python3-defaults (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python3-defaults in Ubuntu. https://bugs.launchpad.net/bugs/1556927 Title: python3 builtin help() fails with exception Status in python3-defaults package in Ubuntu: Fix Released Bug description: The builtin help() function fails with an exception when called on a class that has a data attribute initialized to an object of a class which implements __eq__ in a manner that raises an exception when comparing to None. The attached file, help_bug.py, is a module that illustrates the problem. In an interactive python3 session, importing the module as help_bug and then using the command: help(help_bug) will cause help to fail with a TypeError exception raised by the __eq__ method of the RestrictedCompare class before any help documentation is displayed. In this example, it is the attribute named 'restricted' in the HelpBug class that is causing the problem, specifically its initialization to an object from the RestrictedCompare class. The command help(help_bug.HelpBug) also fails with the exception, although help(help_bug.RestrictedCompare) is successful. This is a result of a comparison of objects that is not protected by try ... except in the classify_class_attrs() function of the standard inspect module. In particular, it is happening at the first comparison of: srch_obj == get_obj when srch_obj is None. The help(help_bug) and help(help_bug.HelpBug) calls successfully display help documentation in Python 2.7. The output of lsb_release -rd is: Description: Ubuntu 14.04.4 LTS Release: 14.04 The package containing the inspect.py file is version libpython3.4-minimal 3.4.3-1ubuntu~14.04.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python3-defaults/+bug/1556927/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
