Can you provide a SF id? I can't seem to find it.
It had been closed or moved out of the SF bug queue by Fred about the same time he left python-dev, I believe. I had sent the HTTPTransport source to Fred, but that sounds like a dead end these days.
Found it: 648658

Does it handle subclasses of str?
I haven't tested, but looking at the implementation, I don't think it will.
In my case, I'm using xmlrpclib in the context of a Cocoa/Python based application that frequently uses Objective-C sourced strings as a part of the RPC request. The PyObjC bridge now bridges NSStrings as a subclass of unicode.
Currently, the Marshaller class in xmlrpclib builds a simple dictionary of types used to encode raw objects to XML.
class Marshaller: ... dispatch = {} ... def dump_string(self, value, escape=escape): self.write("<value><string>%s</string></value>\n" % escape(value)) dispatch[StringType] = dump_string if unicode: def dump_unicode(self, value, escape=escape): value = value.encode(self.encoding) self.write("<value><string>%s</string></value>\n" % escape(value)) dispatch[UnicodeType] = dump_unicode ...
Where the dump method is:
def __dump(self, value): try: f = self.dispatch[type(value)] except KeyError: raise TypeError, "cannot marshal %s objects" % type(value) else: f(self, value)
So, no, it doesn't do subclasses properly. The workaround [for me] was easy... and bogus:
import xmlrpclib Marshaller.dispatch[type(NSString.stringWithString_(''))] = Marshaller.dispatch[type(u'')]
