Hello all,
A bug in '__getattribute__' - magic methods should be fetched from the
class and not go through '__getattribute__'.
This is making a proxy class I'm writing behave very oddly:
The following code:
def DoNothing(*args):
pass
class Something(object):
def __getattribute__(self, name):
print name
return DoNothing
def __call__(self):
print 'called'
def __getitem__(self, name):
raise Exception('w00t!')
def __setitem__(self, name, value):
raise Exception('w00t!')
s = Something()
s['fish'] = 3
Does this on CPython:
C:\compile\cext\trunk\cext>descriptors.py
Traceback (most recent call last):
File "C:\compile\cext\trunk\cext\descriptors.py", line 20, in ?
s['fish'] = 3
File "C:\compile\cext\trunk\cext\descriptors.py", line 17, in __setitem__
raise Exception('w00t!')
Exception: w00t!
And this on IronPython 2a5:
C:\compile\cext\trunk\cext>C:\compile\IronPython2\ipy.exe -D
-X:TabCompletion -X
:ColorfulConsole descriptors.py
__setitem__
To make things odder - if the class 'Something' doesn't have a
__setitem__ method then an attribute error is correctly raised. For
'__call__' I am *sometimes* seeing that go through '__getattribute__'
and sometimes not...
