Implementing tornado chat server with web2py

[Saurabh Kumar]

 Hi,

We are planning to implement an omegle.com like chatting server. We have decided to use webpy for the same. Which out of tornado or twisted framework would be advisable? Is there any other framework especially suitable for this particular application?


Thanks

Saurabh

Look into this:

http://code.google.com/p/web2py/source/browse/gluon/contrib/comet_messaging.py

I would go with tornado or gevent. They seems much simpler then
twisted and more in line with the web2py keep-it-simple phylosophy.

Are you aware of comet_messaging.py (http://code.google.com/p/web2py/source/browse/gluon/contrib/comet_messaging.py) -- it uses Tornado? Here's a three part tutorial on using it with Socket.IO for a chat application: http://greg.thehellings.com/2011/04/web2py-websockets-and-socket-io-part-i-basic-display/

Hi,

Thanks for the replies. So we will decide upon tornado or gevent.
One particular concern in our project is to implement the server
efficiently. We want a server that can handle thousands of users
chatting simultaneously. Would a simple code like comet_messaging.py
be that capable or we need to think of some other improvements over
this?

Thanks

For a chatting server comet_messaging.py is all you need. It already
support groups which you can think of as chat-rooms.

Thanks again for the reply.
The chat room thing is OK. Instead what I am concerned about is if the
code is efficient enough to handle thousands of request.

It should be. That's why Tornado is used -- it is a non-blocking web server. See http://www.tornadoweb.org/.

looks like websockets dont work any more with the couple chrome/tornado => error : Unexpected response code: 426

[Red Arrow]

for chatting, usually use XMPP like Gtalk or facebook chat. If
choosing between gevent or tornado, gevent can handle better than
tornado.

I implemented a similar solution, but the user keeps on getting disconnected from the tornado server. This happens frequently with chrome. Any guesses, so as why the user is being disconnected so often (in every 4-5 secs).

Websocket is not ready , it is just a draft protocol. i wont recommend any serious use on it.

Regarding the error 426 mentionned, I don't know if you tried to use chromium instead of chrome. At least I has the 426 error in chromium, but NOT with chrome. Hope this helps.
