[Zope3-Users] Issue with xmlrpc call to zope3 xmlrpc view hanging, until original call interupted.

[Tim Hoffman]

Hi

I wonder if anyone can shed some light  on a problem I am having with
xmlrpc calls to a zope3 server.

I am running zope3 from buildout on python2.5 on unbuntu.

I have a view defined for xmlrpc (zope.app.publisher 3.5.0)  the same
view is also defined for jsonrpc using z3c.jsonrpc

I am testing with xmlrpclib and the z3c.jsonrpc proxy

Everything works fine when testing the jsonrpc call. However when
performing the xmlrpc call
the call hangs, until I either kill the server, or the ctl ^c the test.

I know the zcml registration for the view is correct as I end up in
the method of the view on the server,because
I can put

import pdb
pdb.set_trace()

in the method in question, and when I kill the client socket the
server thread advances to the set_trace call
and I get the stacktrace on the client as follows

Traceback (most recent call last):
  File "bin/python", line 136, in <module>
    execfile(sys.argv[0])
  File "x.py", line 6, in <module>
    print x.iba.stores.name()
  File "/usr/lib/python2.5/xmlrpclib.py", line 1147, in __call__
    return self.__send(self.__name, args)
  File "/usr/lib/python2.5/xmlrpclib.py", line 1437, in __request
    verbose=self.__verbose
  File "/usr/lib/python2.5/xmlrpclib.py", line 1185, in request
    errcode, errmsg, headers = h.getreply()
  File "/usr/lib/python2.5/httplib.py", line 1199, in getreply
    response = self._conn.getresponse()
  File "/usr/lib/python2.5/httplib.py", line 928, in getresponse
    response.begin()
  File "/usr/lib/python2.5/httplib.py", line 385, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.5/httplib.py", line 343, in _read_status
    line = self.fp.readline()
  File "/usr/lib/python2.5/socket.py", line 331, in readline
    data = recv(1)
KeyboardInterrupt


It seems as if the publisher for xmlrpc is not reading everything from
the socket.

I have been using xmlrpclib for years against zope2 and never
experienced sort of problem, and my current python 2.4 and 2.5
xmlrpclib in ubuntu
works fine against existing zope2 servers.

I am using paste.httpserver .

Any ideas, things I could try to diagnose the problem?
