Hi everyone,

(Sorry for the double-send if any, i'm not sure the first send was performed, maybe because of bounce errors according to mailman.)


I'm currently trying to understand an error when using the dokuwikixmlrpc python module, allowing to easily work with DokuWiki RPC interface.

Another description of the problem :
        https://github.com/kynan/dokuwikixmlrpc/issues/8

Here is the code, tailored to work with the DokuWiki RPC interface:

    from urllib.parse import urlencode
    import xmlrpc.client as xmlrpclib

    URL = 'wiki.example.net'
    USER = 'user'
    PASSWD = 'password'
    USER_AGENT = 'DokuWikiXMLRPC  1.0  for testing'

    script = '/lib/exe/xmlrpc.php'
    url = URL + script + '?' + urlencode({'u': USER, 'p': PASSWD})
    xmlrpclib.Transport.user_agent = USER_AGENT
    xmlrpclib.SafeTransport.user_agent = USER_AGENT
    proxy = xmlrpclib.ServerProxy(url)

    v = proxy.dokuwiki.getVersion()
    print(v)

When ran with Python 3.7 (a personnal debian server, or a personal windows computer), i obtain the expected 'Release 2018-04-22a "Greebo"' as ouput. When ran with Python 3.9 (my personnal, manjaro machine), i obtain the following stacktrace:

    Traceback (most recent call last):
      File "/home/project/read.py", line 32, in <module>
        v = proxy.dokuwiki.getVersion()
      File "/usr/lib/python3.9/xmlrpc/client.py", line 1116, in __call__
        return self.__send(self.__name, args)
      File "/usr/lib/python3.9/xmlrpc/client.py", line 1456, in __request
        response = self.__transport.request(
      File "/usr/lib/python3.9/xmlrpc/client.py", line 1160, in request
        return self.single_request(host, handler, request_body, verbose)
File "/usr/lib/python3.9/xmlrpc/client.py", line 1190, in single_request
        raise ProtocolError(
xmlrpc.client.ProtocolError: <ProtocolError for wiki.example.net/lib/exe/xmlrpc.php: 401 Unauthorized>

I don't have the possibility to test this on python 3.8 specifically, but since the XML and XMLRPC modules have been updated in 3.8, and since 3.9 doesn't seems to introduce any change for them, i would expect 3.8 to introduce some change that dokuwikixmlrpc has somehow to take into consideration.

Can anyone help me with that one ? I don't know anything about RPC and XML, i don't know what i need to do know to fix dokuwikixmlrpc.

Best regard,
