Hi Dave! Thanks for taking the time to contribute.

Unfortunately, this contribution will almost certainly be lost if you don't open a ticket for it at http://twistedmatrix.com/trac/newticket. Once you've done that, you'll need to mark it for review by adding the "review" keyword and reassigning it to nobody - the empty entry at the top of the "reassign" menu.

Thanks for your thoughtful comments! I created a ticket with a patch and unit test and tried to respond to all of the things you mentioned. The ticket is here:

I had to add to the XMLRPCIntrospection class in order to include my method in the system namespace, even though it is not really an introspection method. It's also possible to subclass XMLRPCIntrospection from outside of xmlrpc.py and use putSubHandler instead of xmlrpc.addIntrospection to create the "system" namespace.

I'm not quite sure what you're getting at here - do you think one of these other approaches would be better!

Well, I'm sort of thinking out loud here, because I'm not sure. As designed, the way to get a "system" namespace in your XML-RPC server is to call xmlrpc.addIntrospection(server). However, the "system.multicall" method belongs to the "system" namespace and is not an introspection method. If I were to add another method called xmlrpc.addMulticall(), the two methods would both be responsible for creating the system namespace. Would the multicall method go in its own class? Or would it be monkey-patched onto the XMLRPCIntrospection class? The latter would avoid breaking existing code, but it would also create an order of operations requirement (first introspection, then multicall), which would be inelegant.

For comparison, this is how SimpleXMLRPCServer does it: http://docs.python.org/library/simplexmlrpcserver.html#SimpleXMLRPCServer.Si...

I'll be around as "ramenboy" - maybe I'll see you around.

Thanks, Dave
