Trustin Lee updated DIRMINA-45:
-------------------------------
Summary: DemuxingProtocolCodecFactory.doDecode is called even if the buffer
became empty. (was: DemuxingProtocolCodecFactory.doDecode returns wrong value)

> Key: DIRMINA-45
> URL: http://issues.apache.org/jira/browse/DIRMINA-45
> Project: Directory MINA
> Type: Bug
> Versions: 0.7.1
> Environment: JDK1.4.2
> Reporter: Alex
> Assignee: Trustin Lee
> Fix For: 0.7.2
>
> I am not sure if it is a bug or I just misunderstood something.
> I am implementing a protocol and use Demuxing* classes.
> When I return MessageDecoder.OK from my MessageDecoder's decode method, MINA
> tries repeatedly calls this method again. If I return
> MessageDecoder.NEED_DATA everything goes fine.
> So, I would expect completely reversal behaviour.
> I checked CumulativeProtocolDecoder and DemuxingProtocolCodecFactory classes.
> In CumulativeProtocolDecoder.decode it says that doDecode is invoked
> repeatedly until it returns false. Fine. But what "false" means here? I would
> guess that it means that buffer was completely decoded and no more data is
> needed. But DemuxingProtocolCodedFactory.doDecode returns true if decoder
> returned MessageDecoder.OK and false if decoder returned
> MessageDecoder.NEED_DATA. Isn't wrong here?
