Changes

This new version comes with complete rewrite of the SSL/TLS layer. The previous implementation had some flaws that were difficult to fix or workaround, and with the arrival of TLS-1.3, it was the opportunity to review and recode this part, which is the main change.

It also contain some minor fixes (ignored tests being fixed, a minor infinite loop fixed in the Buffer toString() method if used in some corner case, etc)

For any information about the API modifications and the impact on existing application, please read the 2.1 vs 2.0 page.

MINA 2.1.3 released posted on June, 2, 2019

The MINA project is pleased to announce a new release, MINA 2.1.3. This is a bug fix release: it fixes a 100% CPU usage in some corner case. Here are the fixed issues :

• DIRMINA-1095 Seems like the management f UDP sessions is really unneficient
• DIRMINA-1107 SslHandler flushScheduledEvents race condition, redux
• DIRMINA-1111 100% CPU (epoll bug) on 2.1.x, Linux only

For any information about the API modifications and the impact on existing application, please read the 2.1 vs 2.0 page.

MINA 2.1.2 released posted on April, 20, 2019

The MINA project is pleased to announce a new release, MINA 2.1.2. This is a bug fix release: it fixes an issue for applications using SSL/TLS, which will stall waiting on a WriteFuture because it does not get signaled when the message has been fully sent.

For any information about the API modifications and the impact on existing application, please read the 2.1 vs 2.0 page.

MINA 2.1.1 & MINA 2.0.21 released posted on April, 14, 2019

The MINA project is pleased to announce two new releases, MINA 2.1.1 and MINA 2.0.21.

These are fixing a critical issue, CVE-2019-0231

CVE-2019-0231: ‘Handling of the close_notify SSL/TLS message does not lead to a connection closure, leading the server to retain the socket opened and to have the client potentially receive clear-text messages which were supposed to be encrypted.’

MINA 2.1.1 also fixes the CompressionFilter usage, by simplifying the way we proceed with writes. A side effect is that it should be slightly faster to write data from an application. (This fix is not included in 2.0.21)

We urge anyone using any previous MINA version to migrate to one of those two new versions

MINA 2.1.0 released posted on March, 14, 2019

The MINA project is pleased to announce a new release, MINA 2.1.0. This is a evolution over the 2.0.x branch, with some API modifications that makes it incompatible.

That means some effort will be required from applications to be able to use Apache MINA 2.1.0 as a replacement for Apache MINA 2.0.20.

Otherwise, every fix applied in Apache MINA 2.0.20 has been ported to this version, so one can still keep going with Apache MINA 2.0.20 which will be maintained for the coming months.

For any information about the API modifications and the impact on existing application, please read the 2.1 vs 2.0 page.

MINA 2.0.20 released posted on February, 24, 2019

The MINA project is pleased to announce a new release, MINA 2.0.20, fixing some API issues:

• DIRMINA-1092 Removed a spurious printstacktrace
• DIRMINA-1098 handshakeStatus variable has been wrongly made global
• DIRMINA-1088 the OrderedThreadPool implementation has been made Java 10 compatible

We urge you to switch to this version if you were using MINA 2.0.19 or any older version.

MINA 2.0.19 released posted on June, 11, 2018

The MINA project is pleased to announce a new release, MINA 2.0.19, fixing some API regression:

• the ‘event’ message has been removed from the IoHandler interface
• the SESSION_SECURED/SESSION_UNSECURED message are back

Those changes have been introduced in MINA 2.0.18 by mistake, and break applications that were working with MINA 2.0.17.

They will be reintroduced in MINA 2.1.0

We urge you to switch to this version if you were using MINA 2.0.17 or any older version.

MINA 2.0.18 released posted on June, 1, 2018

The MINA project is pleased to announce a new bug fix release, MINA 2.0.18.

There is some important addition in this version, the IoHandler interface now exposes a new method :

void event(IoSession session, FilterEvent event) throws Exception;

This can be used by any filter to generate a specific event (which will be handled on demand by the application).

Currently, the only added event is defined in SslEvent, and it tells if the session has been secured (ie the Handshake has completed) or isn’t anymore.

It changes one thing in your application: if you were implementing IoHandler, you have to add this method. You may also extends IoHandlerAdapter which has a void implementation of this event() method.

The few fixes bugs/added features are:

• Added a flag to tell the Handshake to start immediately or not
• The IoBufferHexDumper implementation now does not modify the IoBuffer position
• Some missing synchronization have been added in teh SslFilter
• The suspendRead call is handled for Datagrams, instead of throwing an exception

We urge you to switch to this version if you were using MINA 2.0.17 or any older version.

MINA 2.0.17 released posted on March, 15, 2018

• DIRMINA-1002 - Mina IoHandlerEvents missing inputClosed enum item.

You can check the list of fixes for this version there :

Release note

MINA 2.0.8 released posted on September, 22, 2014

It’s 2 years we haven’t had a release of MINA 2.0, it’s about time.

We have tried to fix as much issues as we could in the last 3 weeks. As a result, we have closed around 90 JIRAs (fixed, postponed or simply discarded).

There is one change that might break the build for those switching from MINA 2.0.7 to MINA 2.0.8 : the IoHandler interface now has a method called inputClosed(), so either you have to implement this method if you are directly implementing the IoHandler interface, or better, you can extends IoHandlerAdapter, which implements a placeholder for this method.

You can check the list of fixes for this version there :
