Emmanuel Lecharny commented on DIRMINA-1101:
--------------------------------------------
As Jonathan said, the risk is that it breaks something in existing use code
base, something I really can't guarantee with a modified 2.0.X.
OTOH, 2.1 is really close to 2.0, and there should be no impact on your code if
you switch to this version. All in all, we just added an event, which is
handled by default in the \{IoHandlerAdapter}, so your \{IoHandler}
implementation should not be hit unless you were using the SSL notification
(check that: [http://mina.apache.org/mina-project/2.1-vs-2.0.html).]
Is that the case ?

> Key: DIRMINA-1101
> URL: https://issues.apache.org/jira/browse/DIRMINA-1101
> Project: MINA
> Issue Type: Bug
> Affects Versions: 2.0.20
> Reporter: Jörg Michelberger
> Assignee: Emmanuel Lecharny
> Priority: Major
>
> I'm updated from a MINA 2.0.7 to the 2.0.20 and am a user of
> CompressionFilter. Writing of Messages fails with a InvalidMarkException.
> Reproducible Test is:
> * Copy MINA Core Test org.apache.mina.core.service.AbstractIoServiceTest to
> MINA Compression Filter org.apache.mina.filter.compression Test Packages
> package.
> * Adapt package statement to org.apache.mina.filter.compression.
> * Add Compression to acceptor and connector
> * acceptor.getFilterChain().addLast("compression", new
> CompressionFilter());
> acceptor.getFilterChain().addLast("logger", new LoggingFilter());
> acceptor.getFilterChain().addLast("codec",
> new ProtocolCodecFilter(new
> TextLineCodecFactory(StandardCharsets.UTF_8)));
> * connector.getFilterChain().addLast("compression", new
> CompressionFilter());
> connector.getFilterChain().addLast("logger", new LoggingFilter());
> connector.getFilterChain().addLast("codec",
> new ProtocolCodecFilter(new
> TextLineCodecFactory(StandardCharsets.UTF_8)));
> * Set a Breakpoint to java.nio.Buffer.reset() method, where the
> InvalidMarkException is thrown.
> * Run Debug Testfile on
> org.apache.mina.filter.compression.AbstractIoServiceTest
> After the Exception the session is immediatelly scheduled for disconnect.
> It seems that there is a discrepancy between the mark() and reset() calls on
> the underlaying Buffer. In case of compression, a Buffer with the compressed
> content is created and is wrapped with the original Buffer in a
> FilteredWriteRequest, because CompressionFilter is a WriteRequestFilter. This
> is in WriteRequestFilter.filterWrite()
> In DefaultIoFilterChain$HeadFilter.filterWrite() is then the mark() call,
> which is done on the compressed Buffer.
> In AbstractPollingIoProcessor.writeBuffer() is the reset() call, which is in
> this case done on the original Buffer, leading to the Exception.
> It seems that the change at date 16.02.2016
> SHA-1: 44b58469f84ce991074cdc187b1c1f23b94cf445
> * Don't try to reset a message when it's not a IoBuffer
> which reassignes the buf before reset() is called broke it. The buf before
> reassign looks much better as the right to reset() in this case.
