can't get transports demo to work

[hjwp]

seems to serve the main page OK, as well as socket.io.js. when I click "connect" though, it logs "connecting" but doesn't get any further. same in firefox & chromium.

in the server logs, I see:

2011-11-07 16:35:44,642 INFO:Starting up tornadio server on port '8001'

On the client-side, if I open up the firebug console, I see it tries to make a bunch of ajax GET requests to, eg:

http://localhost:8001/socket.io/1/?t=1320683800628

but it doesn't receive a response.

enabling & disabling the various different transport types doesn't seem to make a difference

python 2.6 on debian, FF 7.0.1, Chromium 14.0.835.202 (Developer Build 103287 Linux)

I realise it's early days! any ideas what might be going wrong?

[mrjoes]

No idea - should work without any problems. Do you see any javascript errors?

[hjwp]

wait! i think i'm being an idiot... am running the server on a different machine to the client...

[hjwp]

hm.... some progress, but still no protocols seem to connect. will post detailed error shortly.

trying with server localhost - websockets works fine, other transports not so good:

flashsocket:

GET http://localhost:8001/socket.io/1/?t=1320684913652
[WebSocket] swfobject.embedSWF failed
console.error("[WebSocket] swfobject.embedSWF failed"); 

fallback to jsonp etc - client side errors:

server-side errors:

Try grabbing new Tornadio2 from github - I found issue which might prevent
transports example from working. It is basically one you reported.

Also, support for hybi17 is not in Tornado yet (well, it is, but in Tornado
head), so you might expect some slow down with websocket transport till it
will switch to the xhr-polling.

Thanks,
Serge.

since websockets works ok with a local server, I thought I'd try it on the server. I modify transports/index.html to use

conn = io.connect('http://' + window.location.hostname + ':8001/', {

and I get the following stack trace on attempting to make a websockets connection:

{'t': ['1320685739774']}

sorry if that was all a bit stream-of-consciousness. hope some of it helps.

[mrjoes]

What version of Tornado you're using?

Thanks for bug report though, if Tornado can't parse websocket handshake,
it still calls on_close.

Hey, just to let you know I finally got a chance to take another look at this, and upgrading tornado to the latest version worked (we had it pinned at 2.0)... things are looking good!

can I make a recommendation for a change to your transports demo: in index.html, line 32:

conn = io.connect('http://localhost:8001/', {

to become

conn = io.connect('http://' + window.location.hostname + ':8001/', {

allows server-based test to work transparently...
