allow_none=True in SimpleXMLRPCServer

[Dody Suria Wijaya]

Hi, I faced the same same situation, and my quick problem solving was 
copying SimpleXMLRPCServer.py to current directory, and "patch" this line:

response = xmlrpclib.dumps(response, methodresponse=1)

into

response = xmlrpclib.dumps(response, methodresponse=1, allow_none=True)


Another better approach is to subclass SimpleXMLRPCDispatcher, and 
override just the method that contains above line (copy paste whole 
function + fix the parameter), then copy paste the whole class 
definition of SimpleXMLRPCServer, but change the mixin to your new 
subclass, then give it a new name ie MySimpleXMLRPCServer. Too much 
hassle I guess.

Another alternative might be subclassing Marshall class in xmlrpclib.py
override the __init__ as so self.allow_none always True, then set 
xmlrpclib.Marshall = yournewsubclass. Ie:

#yourserver.py
import xmlrpclib
class MyMarshall(xmlrpclib.Marshall):
     def __init__(self, encoding=None, allow_none=0):
         self.memo = {}
         self.data = None
         self.encoding = encoding
         self.allow_none = 1
xmlrpclib.Marshall = MyMarshall

#...might work...
