Re: How can I call a subclass method from parent class ?
If you use a newstyle class, e.g. class A(object), then you can get the superclass with cls.__base__. You could also use super(cls,cls), although note that it returns a object that isn't exactly the same thing as a class -- but good enough for just accessing attributes. Make sure to check that your superclass isn't , otherwise it'll complain about not having a foo attribute. __base__ is probably easier for this purpose. Also be careful with multiple inheritance. No such thing as __super though. -- http://mail.python.org/mailman/listinfo/python-list
Re: C replacement for Queue module
How about Python 2.4's collections.deque class? Supposedly it's thread-safe, and it's implemented in C. - Jason -- http://mail.python.org/mailman/listinfo/python-list
Re: C replacement for Queue module
As far as Queues go, the adding/popping is apparently done with deque which are implemented in C. The Queue class pretty much just provides blocking operations and is otherwise a very thin layer around deque. As far as primitives go, only threading.Lock is written in C and the others are pure Python, so they're not that fast, which might be a reason for Queue's slowness. As far as writing a custom C module, you could probably leave most of the work to deque and just implement blocking. If you stick to a simple lock primative, you can keep it portable and use Python's abstracted thread interface with an amazing choice of two whole functions: acquire and release. -- http://mail.python.org/mailman/listinfo/python-list
