[Bug 1517397] [NEW] Gunicorn traceback when downloading “not modified” page

[EOLE team]

Public bug reported:

Hello,

We encounter tracebacks in gunicorn-error.log when a client download a
“not modified” page:

    gunicorn-error.log <==
    2015-06-16 11:39:00 [5565] [ERROR] Socket error processing request.
    Traceback (most recent call last):
      File "/usr/lib/python2.7/dist-packages/gunicorn/workers/async.py", line 42, in handle
        req = six.next(parser)
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/parser.py", line 39, in __next__
        self.mesg = self.mesg_class(self.cfg, self.unreader, self.req_count)
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 152, in __init__
        super(Request, self).__init__(cfg, unreader)
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 49, in __init__
        unused = self.parse(self.unreader)
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 164, in parse
        self.get_data(unreader, buf, stop=True)
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/message.py", line 155, in get_data
        data = unreader.read()
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/unreader.py", line 38, in read
        d = self.chunk()
      File "/usr/lib/python2.7/dist-packages/gunicorn/http/unreader.py", line 65, in chunk
        return self.sock.recv(self.mxchunk)
      File "/usr/lib/python2.7/dist-packages/eventlet/greenio.py", line 251, in recv
        return fd.recv(buflen, flags)
      File "/usr/lib/python2.7/socket.py", line 170, in _dummy
        raise error(EBADF, 'Bad file descriptor')
    error: [Errno 9] Bad file descriptor

This problem is reported and fixed upstream
(https://github.com/benoitc/gunicorn/issues/630).

Is it possible to backport the patch?

Regards.
