XML-RPC Bug?

[Jesper Olsen]

Hola,

With xmlrpclib & SimpleXMLRPCServer it is possible to
call procedures remotly, which return various simple
python types.

If I call a procedure that returns nothing, I get a 
"<ProtocolError: 500 Internal error>"

Surely that is a bug?

Example:

Server:

    from SimpleXMLRPCServer import *

    class MyClass:
        def __init__(self):
            self.i=0

        def inc(self):
            self.i+=1

    def simpel_server(port=50000):
        myobj=MyClass()
        server=SimpleXMLRPCServer(("",port))
        server.register_instance(myobj)
        while myobj.i<5:
            server.handle_request()

    simpel_server(50000)


Client:

    import xmlrpclib
    srv=xmlrpclib.ServerProxy("http://localhost:50000")
    try:
        srv.inc()
        srv.inc()
        srv.inc()
        srv.inc()
        srv.inc()
    except xmlrpclib.Error, v:
        print "Error", v


The example works correctly if MyClass.inc() is changed to
always return a dummy value...

Cheers
