Issue #157 resolved

PyPI XMLRPC interface no longer works with Python 2.6

I just tried the documented interfaces for PyPI (https://wiki.python.org/moin/PyPIXmlRpc) with Python 2.6 and it fails with an error:

> python pypirpc.py
Traceback (most recent call last):
  File "pypirpc.py", line 7, in <module>
  File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1199, in __call__
    return self.__send(self.__name, args)
  File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1489, in __request
  File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1253, in request
    return self._parse_response(h.getfile(), sock)
  File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 1390, in _parse_response
  File "/usr/local/python-2.6-ucs2/lib/python2.6/xmlrpclib.py", line 604, in close
    self._parser.Parse("", 1) # end of data
xml.parsers.expat.ExpatError: no element found: line 1, column 0

The call works with Python 2.7. It appears that xmlrpclib is not receiving any body data from the server.

The returned data in 2.7 looks completely harmless:

send: "POST /pypi HTTP/1.1\r\nHost: pypi.python.org\r\nAccept-Encoding: gzip\r\nUser-Agent:
xmlrpclib.py/1.0.1 (by www.pythonware.com)\r\nContent-Type: text/xml\r\nContent-Length:

Could this be a network error rather than a program one ?

The code in 2.7 does a retry in case of a connection reset or abort, which code in 2.6 and earlier does not apply.
