[jira] [Created] (DIRMINA-907) Create a WebSocket iofilter for use
in Apache Mina TCP servers
dhruv chopra created DIRMINA-907:
------------------------------------
Summary: Create a WebSocket iofilter for use in Apache Mina TCP servers
Key: DIRMINA-907
URL: https://issues.apache.org/jira/browse/DIRMINA-907
Project: MINA
Issue Type: New Feature
Components: Filter, Protocol - HTTP, Transport
Reporter: dhruv chopra
Shephertz has created a websocket iofilter that can be added in Apache mina tcp server chain. The features of this codec are
1) Works with binary data sent/received over websocket
2) Abstracts the client details from the Handler code i.e. the handler need not be aware that the remote endpoint is a browser or native client.
3) Tested with binary data sent/received on latest chrome and firefox browsers. IE 9 doesn't support websockets and we will make changes if required for IE 10 when its released and if it supports websockets.

We don't have standalone test for this.. But I just put together a simple
connect/send/receive one - I'm attaching the client html file to use for a
simple test (open in ff or chrome).
You can use the Mina
TimeServer<http://mina.apache.org/quick-start-guide.html>example to
see the filter code in action (with some minor modifications).
After you've added the websocket codec code to your project. Just replace
'main' function and messageReceived with the following...
*public static void main(String[] args) throws IOException {*
* IoAcceptor acceptor = new SocketAcceptor();*
* SocketAcceptorConfig cfg = new SocketAcceptorConfig();*
* cfg.getFilterChain().addLast("wscodec", new ProtocolCodecFilter(new
WebSocketCodecFactory()));*
* acceptor.bind( new InetSocketAddress(12346), new
TimeServerHandler(), cfg);*
* System.out.println("MINA Time server started.");*
*}*
*
*
* @Override*
* public void messageReceived(IoSession session, Object message) throws
Exception {*
* IoBuffer buf = (IoBuffer)message;*
* System.out.println("received "+buf.array().length+" bytes");*
* // send [0 0 0 1] to the client.*
* byte[] resp = new byte[4];*
* resp[3] = 1;*
* *
* session.write(WebSocketCodecPacket
.buildPacket(IoBuffer.wrap(resp)));*
* }*

Hi,
I took a look at it but it miss tests.
do you have some tests to provide ?

Sorry, I was stuck in MINA release (2.0.7) and two other Apache releases...
Now that 2.0.7 is out, I'm focusing on the site and documentation, but I
will definitively look at your code !
Thanks for the polling and sorry for the delay !

Hi Folks,
Wanted to check if anyone has had a chance to play with the code we
submitted for this filter.
In case some information is incomplete, please let me know.
Looking forward to your feedback.

--------------------------------------
Sorry - I'm still a bit new to MINA but I did a few searches and don't know what exactly you are referring to by mina-http! :)
Is there already a http codec that you are suggesting we insert this in to?
I have currently implemented this in a way that it is stand-alone. Since websocket only do an initial handshake over http and every thing onwards is non-http, wouldn't it be overkill to have to include an entire http module?

dhruv chopra commented on DIRMINA-907:
--------------------------------------
I looked at the http codec. From what I understand it is useful where the client and server are speaking in HTTP and the business logic is built on top of HTTP requests/responses (REST for example).
In the case of websockets, the client (browser) and the server don't speak HTTP when sending/receiving data. Only the connection establishment handshake is done using HTTP. Once the handshake is done, the actual data exchanged on that very IoSession has its own encoding/decoding protocol which has nothing to do with HTTP - in fact it is a binary protocol. I have attached an image in which I've tried to illustrate the two different scenarios - please excuse my poor paintbrush skills :-)
IMHO, there is no real need to make the two codecs work together as they are for two different application scenarios. Mixing them will give us a codec with lots of if/else blocks. e.g.: if(msg is WebSocket HANDSHAKE) if(plain HTTP request) if (Websocket binary data)

We do the handshake ourselves in the decoder. This also hides the handshake from the Handler.
