logilab-astng #23986 False positive: E1101 [validation pending]

This is pylint 1.9 on ubuntu lucid.

I am inheriting from defaultdict, and in the implementation of my class I use defaultdict methods - they are all declared as non-existant.

Example:

from collections import defaultdict

class IntDict(defaultdict):

    def __init__(self):
        defaultdict.__init__(self, int)

    def copy(self):
        result = IntDict()
        result.update(self)
        return result

    Same kind of false positive here :
    I'm using pyserial-2.5_rc2 with python 2.6.5 on Archlinux

    import serial
    a = serial.PARITY_NONE

    E: 5: Module 'serial' has no 'PARITY_NONE' member

    This is obviously false as I'm running this test successfully on my machine.

    I get lots of these errors working with Google App Engine. It's pretty frustrating because they overwhelm warnings about real problems. When I do:

    from google.appengine.ext import deferred
def f():
  pass
deferred.defer(f)

    I get an error like:

    [E1101, ...] Module 'google.appengine.ext.deferred' has no 'defer' member

    But of course it does. This seems to happen in cases where the module has a __init__.py file with contents like:

    from deferred import *

    and also a deferred.py file:

    def defer(callable, *args, **kwargs):

      hum pylint should be able to follow such things. May be the pb is related
      to relative import (eg 'from defererred import *' instead of
      'from google.appengine.ext.deferred import *').

      You can file a specific ticket for this pb.

    I don't know if this is pertinent, but I get a E1101 false positive when using "self.__dict__['mykey'] = 'myvalue'" in place of self.mykey = 'myvalue'.

    Hope it could help ...
