[atmosphere.js] long-polling issue with jQuery Atmosphere 0.9 RC3

[mishoboss]

There is a long-polling issue with the latest jQuery plugin. When call the socket.unsubscribe() the HTTP request is aborted, but a new one is initiated after the timeout passes. So, if you call for example 10 times unsubscribe() and then subscribe(), you will have 10 simultaneous HTTP long-poll connections.

Integrated. Please try it and let me know if you can still reproduce (you haven't mention the browser used).

Thank you, but the bug is still there. I test it with Google Chrome.
This is a snapshot from the Chrome's Developer Tools: http://m-design.bg/Capture.JPG
As you can see there are 5 Pending request, while there must be only one, as all others are terminated. But after the 59 seconds timeout, they are started again.

Hum...I need a way to reproduce as I can't reproduce right now. Can you describe a quick way to reproduce?

[mishoboss]

Yes. This is the pattern I use:

socket.unsubscribe();
socket.subscribe(...);

socket.unsubscribe();
socket.subscribe(...);

socket.unsubscribe();
socket.subscribe(...);
....

When socket.unsubscribe() is called, the previous request is aborted. However after the timeout that is specified in the subscribe() passes, it starts another request.

Ok, I've just tested with

    var subSocket = socket.subscribe(request);
    socket.unsubscribe();
    subSocket = socket.subscribe(request);
    socket.unsubscribe();
    subSocket = socket.subscribe(request);
    socket.unsubscribe();
    subSocket = socket.subscribe(request);
    socket.unsubscribe();
    subSocket = socket.subscribe(request);
    socket.unsubscribe();
    subSocket = socket.subscribe(request);

I'm using 0.9-SNAPSHOT (latest version) so and I don't see any reconnect issue. I'm using Firefox and test with the atmosphere-chat sample (atmosphere/sample/chat/)

OK I just find a way to reproduce.
