Server port config lost?

Question

I'm trying to get the Autobahn example to work under a virtual env with Python 3.3 and asyncio 0.4.1, but Chrome keeps displaying a 1006.

After discovering the debug option (factory.debug = True), I encountered the following server output:

[('debug', True, 'WebSocketServerFactory'),
 ('debugCodePaths', False, 'WebSocketServerFactory'),

 ('maxMessagePayloadSize', 0, 'WebSocketServerFactory'),

  'WebSocketServerFactory')]

How can the port be None if it's explicitly set to 9000 in the example?

Answer 1

Uups. We recently merged a patch that allows factories to be defined without providing a WebSocket URL, adjusted the examples, but did no release to PyPi. Sorry.

I just did a release (0.8.6) now. So you can either:

pip install -U autobahn

OR change the example code to

factory = WebSocketServerFactory("ws://localhost:9000")

Sorry again ..
