New submission from Ronald Oussoren: If a class implements __dir__ to also return a number of attributes that aren't present in the class __dict__ inspect.classify_class_attrs gets confused and assumes the home class is None.
This in turn confused pydoc, docclass in pydoc assumes that the 'class' slot in the sequence returned by classify_class_attrs is actually a class and fails when it None (because None doesn't have a __name__ attribute). I've classified this as "low" because I've found a useable workaround: I have implemented a "__objclass__" property for my custom descriptor and with that pydoc works. It would be nice if pydoc wouldn't crash on this. One possible workaround: assume that the class is the inspected class when a name returned by dir(cls) cannot be found in one of the classes on the mro. I'll provide a patch if this would be acceptable behavior. ---------- components: Library (Lib) messages: 179738 nosy: ronaldoussoren priority: low severity: normal stage: test needed status: open title: pydoc confused by __dir__ type: behavior versions: Python 2.7, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16938> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
