rlotun / txwebsocket Goto Github PK

The protocol mentions that the challenge must be computed with concatenation of the keys as "sent on the wire" (the client should shuffle the headers). The current version always takes the order Sec-WebSocket-Key1, Sec-WebSocket-Key2.

Hello,
Is there a way to get access to "connectionMade" so code can be ran when a socket is opened? I'm new to twisted and tried to expose this function, but couldn't figure it out. Thanks.

del for my websockethandler never gets called, the object is never freed even when connections are lost

I've encountered a bug. I can get clients to connect to the server via websockets but when the client disconnects there is an error :
Traceback (most recent call last):

I'm using http://websocket.org/echo.html connecting to my local server. I can provide you if you want some network traces.

Is it possible to get this patched? It's just a minor "bonus" if it was possible. :)

Firefox 7.0.1 sets 'connection' header not to "Upgrade", but "keep-alive, Upgrade".

The next change in WebSocketRequest.process method fixes the problem:

57 line:

•    if connection != "Upgrade"
  

  •    if connection not in ("Upgrade", "keep-alive, Upgrade")
    

For my project, I'd want to be able to put a factory in the Web Socket hierarchy. Could this be implemented?

I get the error ImportError: cannot import name _IdentityTransferDecoder. Google came up with no results. I have Python 2.7

Newest Chromium uses the hybi-10 version of the WebSocket protocol (http://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-10). See http://code.google.com/p/chromium/issues/detail?id=64470 for details.

Both the handshake and the payload format have changed and currently txWebSocket does not work with Chromium.

I'm working on implementing both tha handshake and the new frame format and will create a pull request as soon as I have it done.

In the simple_server.py example, I added only print "init" under the init method.

class Testhandler(WebSocketHandler):
def init(self, transport):
WebSocketHandler.init(self, transport)
self.periodic_call = task.LoopingCall(self.send_time)
print "init", self, transport

On the client-side this is the only code being executed:

var ws = new WebSocket("ws://109.74.200.181:8090/test");
ws.onopen = function()
{
alert('onopen fired!');
//ws.send("message to send");
};

(As you can see I changed the port in this example, but no other changes were made)

This causes output from ONE connection:

init <main.Testhandler object at 0x9e70a6c> <websocket.WebSocketTransport object at 0x9e7018c>
init <main.Testhandler object at 0x9e7062c> <websocket.WebSocketTransport object at 0x9e7018c>

I'm not good at this but it looks like there's two "selfs" or instances being made. And when the browser is being closed, connectionLost is only fired once. This has led to some strange behaviour in one of my applications. Users getting an increasing number of transports added to their "client", never getting cleaned out or "connectionLost".

Can you replicate this, or is it intended?

Following is the traceback from running the code.
