[issue20611] socket.create_connection() doesn't handle EINTR properly

[Florent Xicluna]

New submission from Florent Xicluna:

I had this sporadic traceback in a project:

  File "test.py", line 62, in <module>
    result = do_lqs(client, str(dnvn))
  File "test.py", line 25, in do_lqs
    qualif_service_id = client.create('ti.qualif.service', {})
  File "/srv/openerp/.buildout/eggs/ERPpeek-1.4.5-py2.6.egg/erppeek.py", line 894, in wrapper
    return self.execute(obj, method, *params, **kwargs)
  File "/srv/openerp/.buildout/eggs/ERPpeek-1.4.5-py2.6.egg/erppeek.py", line 636, in execute
    res = self._execute(obj, method, *params)
  File "/srv/openerp/.buildout/eggs/ERPpeek-1.4.5-py2.6.egg/erppeek.py", line 361, in <lambda>

    self.send(msg)
  File "/usr/lib/python2.6/httplib.py", line 739, in send
    self.connect()
  File "/usr/lib/python2.6/httplib.py", line 1112, in connect
    sock = socket.create_connection((self.host, self.port), self.timeout)
  File "/usr/lib/python2.6/socket.py", line 561, in create_connection
    raise error, msg
socket.error: [Errno 4] Interrupted system call



It seems that the EINTR should be caught by the standard library in all cases: http://bugs.python.org/issue1628205

But it's not the case for the "socket.create_connection" method (verified in 3.3 and 2.7 source code).
