[dev] [jira] [Commented] (LIBCLOUD-199) Add http connection timeout to openstack and libcloud connections

Tomaz Muraus commented on LIBCLOUD-199:
---------------------------------------

I just checked the code and it looks like httplib in Python 2.5 doesn't support setting a timeout*.

We need to make sure it also works with 2.5. One of the option would be to set a timeout on a socket, but I don't like this approach, because it's a global setting and also affects other socket operations (e.g. when calling deploy node, etc.)

> Authentication calls to an openstack endpoint (in this case Rackspace) will occasionally create a connection that will stay open indefinitely.  By adding a timeout I can force the connection to close after a few seconds.  That way I can catch this behavior with an exception and log the error before the server request times out.  In this branch I add a timeout kwarg and set a reasonable default of 200 seconds.
