Jonathan Valliere commented on DIRMINA-1101:
--------------------------------------------
There is some concern that the changes may break some projects built with Mina.
(Which is the reason why 2.1.X was added because the SSL changes broke LDAP)
Ultimately, I'm going to defer to Emmanuel on that one.
> InvalidMarkException on session.write when using CompressionFilter.

> 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.
