I found Chris Liechti's example very helpful when working on a similar project. See http://groups-beta.google.com/group/comp.lang.python/msg/d647a830de39d1db . Also, I strongly suggest using threading.RLock() objects instead of primitive locks. With Rlocks one thread can acquire the same lock multiple times without blocking. This is useful if one synchronized method calls another synchronized method. > Obviously, my classes have to instantiate the _lock in __init__ in > order for this to work. The great thing about Chris's example is that the first time a synchronized method is called a lock is instantiated, so you don't have to worry about this step. > Problem: > > When iterating through klass.__dict__.items() in the convenience > method, I only get the instance variables of the class. No functions. > I've found a way to get the function list, by iterating through > klass.__class__.__dict__ . I'm not sure why klass.__dict__.items() isn't working for you. I tried a simple example: class simple(object): def hello(self): print "Hello World" def methods(cls): for name,value in cls.__dict__.items(): if callable(value): print name >>> methods(simple) hello Chris -- http://mail.python.org/mailman/listinfo/python-list
