Websockify "ignoring socket not ready" Firefox 15

I'm using Websockify to connect to a VNC Server (TightVNC) via noVNC. This worked great with Firefox 14.0.1, Chrome 21 and even IE 10. Now I upgraded to Firefox 15 and the problems start:

This is a sample output from websockify:

>websockify.exe 6080 localhost:5900 -v
WARNING: no 'resource' module, daemonizing support disabled
WebSocket server settings:
  - Listen on :6080
  - Flash security policy server
  - No SSL/TLS support (no cert file)
  - proxying from :6080 to localhost:5900

#Connection with Chrome

  1: 79.194.220.16: Plain non-SSL (ws://) WebSocket connection
  1: 79.194.220.16: Version hybi-13, base64: 'True'
  1: connecting to: localhost:5900

Traffic Legend:
    }  - Client receive
    }. - Client receive partial
    {  - Target receive

    >  - Target send
    >. - Target send partial
    <  - Client send
    <. - Client send partial

{<}>{<}>{<}>{<}>{<}>{{<<}>}>{}><}>}>}>}>  1: localhost:5900: Target closed
  1: 79.194.220.16: Client closed, reason: None - None

#Chrome disconnected, Firefox tries to connect

  2: 79.194.220.16: ignoring socket not ready
  3: 79.194.220.16: Plain non-SSL (ws://) WebSocket connection
  3: 79.194.220.16: Version hybi-13, base64: 'True'
  3: connecting to: localhost:5900

Traffic Legend:
    }  - Client receive
    }. - Client receive partial
    {  - Target receive

    >  - Target send
    >. - Target send partial
    <  - Client send
    <. - Client send partial

{<

After the last line websockify hangs, accepting no other connection. Here is the console Ouput from Firefox:

New state 'loaded', was 'disconnected'. Msg: noVNC ready: native WebSockets, canvas rendering

util.js (Zeile 110)

New state 'connect', was 'loaded'.

util.js (Zeile 110)

WebSocket on-error event

util.js (Zeile 110)

New state 'failed', was 'connect'. Msg: Connect timeout


case 'error': Util.Error = function (msg) { console.error(msg); };

util.js (Zeile 111)

Firefox kann keine Verbindung zu dem Server unter ws://ec2-176-34-194-149.eu-west-1.compute.amazonaws.com:6080/websockify aufbauen.


websocket = new WebSocket(uri, 'base64');

websock.js (Zeile 275)

WebSocket on-close event

util.js (Zeile 110)

Received onclose while disconnected (code: 1006)


case 'error': Util.Error = function (msg) { console.error(msg); };

util.js (Zeile 111)

New state 'disconnected', was 'failed'.

As said, this worked perfectly in FF 14.0.1 and still works in Chrome 21 and IE 10.

Any idea why Firefox chrashes websockify? Is this a bug in Firefox Websocket code or a bug in Websockify?

I've replied to your Mozilla bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=789018

In summary, it's a Windows/python problem combined with a mis-feature in firefox 15 (speculative connect).

As a temporary solution you can increase the connect timeout in noVNC.
