New submission from Attila Nagy <bra at fsn.hu>:
When talking to an Apache XML-RPC library based application via python 2.6.5 xmlrpclib, I get this exception:
Traceback (most recent call last):
File "prb.py", line 4, in <module>
proxy.catv.getEndpointIdByIp('1.1.1.1')
File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 1199, in __call__
return self.__send(self.__name, args)
File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 1491, in __request

return self._parse_response(h.getfile(), sock)
File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 1389, in _parse_response
p.feed(response)
File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 601, in feed
self._parser.Parse(data, 0)
File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 868, in end
return f(self, join(self._data, ""))
File "/tmp/Python-2.6.5/Lib/xmlrpclib.py", line 935, in end_struct
dict[_stringify(items[i])] = items[i+1]
IndexError: list index out of range
The exception is caused by the XML response, which includes a value with "ex:i8" type. According to this: http://ws.apache.org/xmlrpc/types.html, there are a lot more types, which are not understood by python's xmlrpclib.
It's easy to fix the above by adding "ex:i8" to the list of end_int dispatcher:
def end_int(self, data):
self.append(int(data))
self._value = 0
dispatch["i4"] = end_int
dispatch["i8"] = end_int
dispatch["ex:i8"] = end_int
dispatch["int"] = end_int
This makes the error disappear (and the program to work).
Of course, it would be nice to support all other types as well (in both directions).
