Summary: WeakValueDictionary.__init__ is backwards
Initial Comment:
>>> from weakref import WeakValueDictionary as wvd
>>> class A:
... pass
...
>>> wvd({1:A()})
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/weakref.py", line 46, in
__init__
UserDict.UserDict.__init__(self, *args, **kw)
File "/usr/lib/python2.4/UserDict.py", line 7, in
__init__
self.update(dict)
File "/usr/lib/python2.4/weakref.py", line 161, in update
d[key] = KeyedRef(o, self._remove, key)
AttributeError: WeakValueDictionary instance has no
attribute '_remove'
WeakValueDictionary.__init__ calls UserDict.__init__
first and sets self._remove second. It should do it the
other way around. This is a regression from 2.3.
