IPv6 sockets not supported

[Carst-Tankink]

When a WebSocket is created using an underlying IPv6 socket, its local_address (and, I assume, the peer address) returns a 4-tuple instead of a 2-tuple.

This means that automatic unpacking of the address into hostname, port throws a ValueError.

Minimal example (using the cherrypy tools)

import cherrypy
from ws4py.server.cherrypyserver import WebSocketPlugin, WebSocketTool
from ws4py.websocket import EchoWebSocket

cherrypy.config.update({'server.socket_port': 9000})
cherrypy.config.update({'server.socket_host': "::1"})
WebSocketPlugin(cherrypy.engine).subscribe()
cherrypy.tools.websocket = WebSocketTool()

class Root(object):
    @cherrypy.expose
    def index(self):
        return """<script type="text/javascript">
      var sock = new WebSocket("ws://localhost:9000/ws");</script>"""

    @cherrypy.expose
    def ws(self):
      pass

cherrypy.quickstart(Root(), '/', config={'/ws': {'tools.websocket.on': True,
                                                 'tools.websocket.handler_cls': EchoWebSocket}})

This throws a ValueError when navigating to localhost:9000

The obvious workaround is not using IPv6 addresses in the server deployment.

A fix would be to have WebSocket.local_address and WebSocket.peer_address return the first two elements of the underlying socket's name.

Good catch. I never recall to perform tests against IPv6. I will have a look.

I've re-worked the client as well as so that it handles ipv6 addresses such as ws://[::6]:9000
