Category: Python Library Group: Python 2.2 Status: Open Resolution: None Priority: 5 Submitted By: Skip Montanaro (montanaro) Assigned to: Nobody/Anonymous (nobody) Summary: xmlrpclib won't marshal new types

Initial Comment: Maybe xmlrpclib should be modified to allow it to marshal subclasses of builtin types (ints, strings, etc). Here's a simple example that demonstrates that it currently won't work with a subclass of str:

import xmlrpclib class MyString(str): ... pass ... s = MyString("sdfsdfsdf") s 'sdfsdfsdf' s.class <class '__main__.MyString'> xmlrpclib.dumps((s,)) Traceback (most recent call last): File "", line 1, in ? File "/usr/local/lib/python2.2/xmlrpclib.py", line 752, in dumps data = m.dumps(params) File "/usr/local/lib/python2.2/xmlrpclib.py", line 448, in dumps self.__dump(v) File "/usr/local/lib/python2.2/xmlrpclib.py", line 459, in __dump raise TypeError, "cannot marshal %s objects" % type(value) TypeError: cannot marshal <class '__main__.MyString'> objects

  1. anything but the base types aren't part of the xmlrpc spec

  2. be very very careful about unmarshalling any but basic objects, because of possible security attacks. See item 471893 for some more info.
