Yes, I see, here is an example, it's using twisted, but I think it's a
python problem (that's why I wrote here). The code for the parent
classes is here
(http://twistedmatrix.com/trac/browser/trunk/twisted/words/xish/xmlstream.py)
xmlstream.XmlStreamFactory in the following code is supposed to be
MyFactory in the previous example, and MyXmlFactory is supposed to be
(xmlstream.XmlStreamFactory. If you uncomment the two commented lines in
MyXmlStreamFactory it works, if they are commented it doesn't. The
parent class (XmlStreamFactory) inherits from two classes :
XmlStreamFactoryMixin (where args and kwargs are defined)
and
protocol.ReconnectingClientFactory.
I think it may be because of the multiple inheritance that I'm getting
this, maybe since the child class doesn't define the __init__() method.
To test, run the following code in one terminal, and run :
netcat localhost 4321
in another (it will crash right away with the lines commented).
Thanks,
Gabriel
