[jira] [Commented] (DIRMINA-1116) Session Message Order Is Mixed Up
Using NioSocketAcceptor
[ https://issues.apache.org/jira/browse/DIRMINA-1116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16854095#comment-16854095 ]
Jonathan Valliere commented on DIRMINA-1116:
--------------------------------------------
You sure there isn't a {{ExecutorFilter}} somewhere in there, on either side? There is no way for anything to be out of order unless it is the fault of the user-application.
> Session Message Order Is Mixed Up Using NioSocketAcceptor
> ---------------------------------------------------------
>
> Key: DIRMINA-1116
> URL: https://issues.apache.org/jira/browse/DIRMINA-1116
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.1.2
> Environment: Windows
> Reporter: Charlie
> Priority: Major
>
> The application requires clients to send communications in a specific sequence.
> For some reason the messages received by a session sometimes get processed out of order by MINA.
> Here is my usage of MINA:
> {code:java}
> //Setup filter chain
> DefaultIoFilterChainBuilder chain;
> acceptor = new NioSocketAcceptor(Runtime.getRuntime().availableProcessors() + 1);
> chain = acceptor.getFilterChain();
> chain.addLast("codec", new ProtocolCodecFilter(new ApplicationProtocolCodecFactory()));
> chain.addLast("authentication", new AuthenticationFilter());
> chain.addLast("inputVerification", new InputValidatorFilter());
> acceptor.setHandler(handler);{code}
> The messages are already out of order in the protocol decoder filter.
> The client application sends messages using one thread and uses tcp so it can't be sending out of order.
> Is this intended behavior due to the async model?
