New submission from Miroslav Stampar:
httplib module's auxiliary class LineAndFileWrapper contains a readline()
method having no arguments (than self). It's being used in code where commented
with "assume it's a Simple-Response from an 0.9 server" as a wrapper for
response stream ("self.fp = LineAndFileWrapper(line, self.fp)").
In some cases readline() method requires a size argument (e.g. used with size
argument inside HTTPMessage/readheaders(), HTTPResponse/begin(),
HTTPResponse/_read_chunked, HTTPConnection/_tunnel, at least in "Python 2.7.1+
(r271:86832, Sep 27 2012, 21:12:17)").
This bug is hard to be reproduced as it requires a little help of "divine
intervention".
One such exception looks like (reproduced on one user machine):
...
conn = urllib2.urlopen(req)
File "/usr/lib/python2.7/urllib2.py", line 127, in urlopen
return _opener.open(url, data, timeout)
File "/usr/lib/python2.7/urllib2.py", line 401, in open
response = self._open(req, data)
File "/usr/lib/python2.7/urllib2.py", line 419, in _open
'_open', req)
File "/usr/lib/python2.7/urllib2.py", line 379, in _call_chain
