 When socket_port is specified as 0, an exception is thrown as follows:

 {{{

 line 247, in wait_for_occupied_port
     raise IOError(msg)
 IOError: Port 0 not bound on 'localhost'
 }}}

 I am using the latest code from the trunk. It appears to me that even
 though wsgiserver is properly passing 0 to socket.bind (and hence binding
 to an unused port), other parts of the code still use "configured" port
 which is 0.

Comment (by draghu...@gmail.com):

 I am attaching a small patch that seems to work with port 0. My only
 intention in uploading the patch is to suggest it as a starting point. It
 will take more time for me to understand all its implications and suggest
 a more thorough solution.

 The web server will update its bind_addr after doing socket.bind() so that
 correct port can be obtained. This port will obviously be different from
 the original port if the original port was 0. Unfortunately, the code that
 started the web server needs to wait for this setting before proceeding
 further. Right now, I just added time.sleep(5) as I don't know of a better
 solution.

Comment:

 That's a good start, but there's no API guarantee that a given httpserver
 will possess a "bind_addr" attribute. So we'd either need to add that to
 the API (which is fine, just needs to be decided) or use some other method
 of passing that information back up to the Server object.

 If we ''did'' add a "bind_addr" requirement, that would mean we could stop
 using a dict for httpservers and use a list instead (and consumers could
 inspect [server.bind_addr for server in httpservers] if they cared). That
 might be the way to go.
