[New-bugs-announce] [issue14826] urllib2.urlopen fails to load URL

[Wichert Akkerman]

New submission from Wichert Akkerman <wichert at wiggy.net>:

There appears to be an odd networking issue with how urllib2 sends HTTP requests. Downloading an image from maw.liquifire.com gives an error:

$ python -c 'import urllib2 ; urllib2.urlopen("http://maw.liquifire.com/maw?set=image[2302.000.13314 a]&call=url[file:325x445]")'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.7/urllib2.py", line 400, in open
    response = self._open(req, data)
  File "/usr/lib/python2.7/urllib2.py", line 418, in _open
    '_open', req)
  File "/usr/lib/python2.7/urllib2.py", line 378, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.7/urllib2.py", line 1207, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib/python2.7/urllib2.py", line 1180, in do_open
    r = h.getresponse(buffering=True)
  File "/usr/lib/python2.7/httplib.py", line 1030, in getresponse
    response.begin()
  File "/usr/lib/python2.7/httplib.py", line 407, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.7/httplib.py", line 365, in _read_status
    line = self.fp.readline()
  File "/usr/lib/python2.7/socket.py", line 447, in readline
    data = self._sock.recv(self._rbufsize)
socket.error: [Errno 104] Connection reset by peer

Downloading the same image using wget works fine:

$ wget 'http://maw.liquifire.com/maw?set=image[2302.000.13314 a]&call=url[file:325x445]'
