Package: python2.2
Version: 2.2.1-4.7
Severity: important
Several of our applications use the XMLRPC for interapplication
communication. After upgrading to python2.2 (2.2.1-4.7), our
applications stopped working. XMLRPC calls receive this type of error:
[EMAIL PROTECTED]:[~/python2.2-bug] python2.2 XMLRPCClient.py
Traceback (most recent call last):
File "XMLRPCClient.py", line 9, in ?
print client.TestAPI("boo")
File "/usr/lib/python2.2/xmlrpclib.py", line 821, in __call__
return self.__send(self.__name, args)
File "/usr/lib/python2.2/xmlrpclib.py", line 975, in __request
verbose=self.__verbose
File "/usr/lib/python2.2/xmlrpclib.py", line 853, in request
return self.parse_response(h.getfile())
File "/usr/lib/python2.2/xmlrpclib.py", line 896, in parse_response
return u.close()
File "/usr/lib/python2.2/xmlrpclib.py", line 571, in close

xmlrpclib.Fault: <Fault 1: 'exceptions.Exception:method "TestAPI" is not
supported'>
Running these applications on 2.2.1-4.6, they work fine.
I've looked at the published patch from python, and I'm not sure why
their patch would cause this problem. So perhaps it is an issue in the
debian patch, or perhaps, the python patch is broken too. Or.. perhaps
I am a moron, and I'm just blind as to why this isn't working. It was
certainly a surprise to us when all of our internal systems stopped
working, so I suspect it might surprise some other folks too. I have
even tried setting allow_dotted_names=True to bypass this problem
(which... supposedly should turn off the security patch), but it's still
broken.
I have attached some sample cases to make this easy for you to
reproduce:
If you run this on a 2.2.1-4.6
python2.2 XMLRPCServer.py 1 &
python2.2 XMLRPCClient.py
it will work fine and dandy
if you run this on a 2.2.1-4.7:
python2.2 XMLRPCServer.py 1 &
python2.2 XMLRPCClient.py
you'll get:
Traceback (most recent call last):
File "XMLRPCClient.py", line 9, in ?
print client.TestAPI("boo")
File "/usr/lib/python2.2/xmlrpclib.py", line 821, in __call__
return self.__send(self.__name, args)
File "/usr/lib/python2.2/xmlrpclib.py", line 975, in __request
verbose=self.__verbose
File "/usr/lib/python2.2/xmlrpclib.py", line 853, in request
return self.parse_response(h.getfile())
File "/usr/lib/python2.2/xmlrpclib.py", line 896, in parse_response
return u.close()
File "/usr/lib/python2.2/xmlrpclib.py", line 571, in close
raise apply(Fault, (), self._stack[0])
xmlrpclib.Fault: <Fault 1: 'exceptions.Exception:method "TestAPI" is not
supported'>
You can change the "1" to a "0" if you want to try the
allow_dotted_names=True flag.. which doesn't appear to do anything to
help.
If you modify the SampleAPI class and add:
def _dispatch(self, method, params):
return apply(getattr(self,method), params)
Everything will work fine... (which is what I did to bootstrap our
systems back into operation).. but obviously this is not supposed to be
necessary.
