The following code snippet is taken from the Python 2.6 multiprocessing documentation with a simple change and this change does not work. I would like to know how to make it work or something similar. I want to pass a Connection object to the MathsClass. I get the following error on Windows:
Traceback (most recent call last): File "c:\apps\python26\lib\multiprocessing\managers.py", line 214, in serve_cl ient request = recv() TypeError: Required argument 'handle' (pos 1) not found from multiprocessing.managers import BaseManager from multiprocessing import Pipe # I added this class MathsClass(object): def set(self, conn): # I added the set() function self.conn = conn def add(self, x, y): return x + y def mul(self, x, y): return x * y class MyManager(BaseManager): pass MyManager.register('Maths', MathsClass) if __name__ == '__main__': parent_conn, child_conn = Pipe() # I added this manager = MyManager() manager.start() maths = manager.Maths() print maths.add(4, 3) # prints 7 print maths.mul(7, 8) # prints 56 maths.set(child_conn) # I added this, error is thrown here -- http://mail.python.org/mailman/listinfo/python-list
