Scattering and Gathering strategy for MINA and more

[p v <ic...@yahoo.com>]

Hi *, 

to the core Team, do you provide NIO Scattering and
Gathering I/O strategy ? (reminder: several buffers to
manage message)  -> helpfull to manage message header
and body seperatly with different king of bytes
mapping? (HTTP, SIP ,...) thanks to Mickael and Robert
to let me think about that ... with previous
messages,)

for all, is there any MINA-SIP opensource released
...thinking about a JAIN-SIP implementation ?

Still waiting zero-copy socket from the jdk! ^^)

Re: Need a concrete or mock class of Protocol Session for tests

Hi,

>From what I've seen, mock objects are fantastic - but use them only as
a last resort.  If possible break up your functionality in a way that
you can call it from your unit test without mocking any objects.

If you do go and create a mock object of ProtocolSession, then I'd
advise you to do so against a final MINA release so that you dont have
to keep changing the recorded method calls.

I believe MINA uses easymock for mock objects.

HTH,
Vinod.

Need a concrete or mock class of Protocol Session for tests

[Serkan Demir <se...@oksijen.com>]

Hi guys,

I have implemented a protocol stack with MINA. Now, I have to increase 
my unit tests coverage. I have stuck at the testing of my 
ProtocolHandler's methods (sessionCreated,sessionOpened, sessionClosed 
etc..) Therefore i need a concrete or mock class of Protocol Session for 
my tests. I noticed the TestSession class in your codebase, but it is 
private class like as ProtocolSessionImpl. Is there any session factory 
or a public concrete class of ProtocolSession which I can use for tests? 
If your answer is no, i will pass to my second alternative, JMock.

I am talking about unit tests of such method.Unless i create a session 
in unit test scope, i cannot test its functionality. Could you recommend 
a way for testing such methods?

    public void messageReceived(ProtocolSession session, Object message) {
        if (BaseStackLogger.logger.isDebugEnabled()){
            BaseStackLogger.logger.debug("Message is received. Message 
is:"+message.toString());
        }

 // some other actions have been done
//
//
     if(!message instanceof MyMessageType) {
    session.close();
    }
     resetTimer();
    }

MINA doesn't support gathering write or scattering read at all for now.  We
are considering implementing gathering write, but will there be performance
improvement here?

for all, is there any MINA-SIP opensource released

Not yet unfortunately, AFAIK.

HTH,
Trustin
