The official JBoss Cache blog

I've just released a minor version on 2.1.0 "Alegrias", with some pretty important bug fixes. These include:

• [ JBCACHE-1329 ] double removal on optimistic locking leaving stale nodes
• [ JBCACHE-1170 ] Leakage of marshalling region stored in ThreadLocal causes partial state transfer to fail when multiple regions present
• [ JBCACHE-1309 ] Unguarded adding of nodes to workspace
• [ JBCACHE-1310 ] Marshalling failure with optimistic PREPARE
• [ JBCACHE-1325 ] ClassLoader and probable memory leak in ReusableObjectInputStream
• [ JBCACHE-1326 ] TxInterceptor leaks MethodCall to thread
• [ JBCACHE-1316 ] recycleQueue.put() could block forever halting evictions and eventually any replications

Other improvements include enhancements to configuration and performance:

• [ JBCACHE-1315 ] Eviction inaccuracy
• [ JBCACHE-1218 ] System property substitution in config file parsing

For a full list of JIRAs included in this release, please see the release note report. As this is the latest and greatest of JBoss Cache 2.X, I would encourage anyone who is using a 2.X release to switch to 2.1.1.GA.

Enjoy!

Labels: 2.1.1.GA, alegrias, release

The much-awaited JBoss Cache 2.1.0.GA release is now public and available.

In addition to a few bugfixes on 2.0.0, 2.1.0 adds a few new features such as a reconnectable TcpDelegatingCacheLoader, some new API convenience methods (reminiscent of the 1.x API), and a new notifier callback to inform listeners when a buddy group changes membership. And a lot of internal refactoring to make the code leaner, faster and more robust/maintainable. See JIRA for the full list of changes and enhancements.

Downloads are in the usual place. Everyone on 2.0.0 should upgrade - there are some pretty significant bug fixes here.

I must give special thanks to Mark Newton, JBoss.org's content lead who has helped with revamping the JBoss Cache documentation making it much more readable and easy to follow. Check out the very cool code-snippet syntax highlighting!!

Finally, a couple of things have changed with our user forums as well - there are now separate forums for Core and POJO editions of the cache; please use the relevant forum when discussing JBoss Cache. It helps us organise information better, helping you find stuff on older threads.

Enjoy!

Yes, I know I've been crap at announcing new releases, but in the past 2 weeks we've released a new SP on the 1.4.1 series as well as a new CR on 2.1.0.

2.1.0.CR2 is moving swiftly along towards GA, although I foresee at least 2 more CRs before release - this is going to be a rock-solid stable GA. I'm planning some pretty significant performance enhancements for CR3 as well, but please download CR2 for now and provide as much feedback as you can. It all helps.

1.4.1.SP8 contains some pretty significant bug fixes, particularly around buddy replication and optimistic locking. Please see the changelog for details.

Downloads on http://labs.jboss.org/jbosscache/downloads as usual, and the forums and JIRA are in the usual places.

Enjoy, and Merry Christmas.

Over the weekend we've released JBoss Cache 2.1.0.CR1 (Alegrias) as well as a patch release on Cayenne, 1.4.1.SP6.

Anyone using the 1.4.x series, especially with buddy replication, is encouraged to upgrade to this patch release.

In addition, I'd encourage everyone to download and try out Alegrias, especially if you use 2.0.0 Habanero. Your feedback on this release is very important, as we hope this is a natural upgrade path from Habanero.

The downloads are available on the JBoss Cache downloads page, and the docs on the JBoss Cache docs page.

Enjoy,

Since releasing Habanero, I've been busy changing a few things around the way the source tree is managed (it was getting pretty messy). Basically, a lot of this revolves around JBCACHE-1142 which involves a number of changes. Let's take these one at a time.


1. Source code repository

We've moved from CVS to subversion. Still hosted on JBoss.org though, the main driver behind this was to be able to move files and directory structures around and not lose revision history.

Details of how to access the new repository are on the JBoss Cache wiki - committer rights have been carried across from CVS.


2. Structure

We've split POJO Cache into a separate module for easier dependency management. So now jbosscache-core and jbosscache-pojo can be built separately. See the wiki link above for more details.



3. Build tool

We've ditched ant in favour of Maven2. This affects the way the project is built and the way deliverables are created, but makes dependency management that much easier. So after a few hair-tearing days getting it to behave just the way I wanted it, we're finally ready here. Details of how to use Maven2 to build JBoss Cache are in the README-maven.txt file in the src tree.


4. TestNG

We're in the process of ditching the ageing JUnit 3.8-based test suite in favour of one based on TestNG. The reason behind this decision is so we can group and parameterise tests better, so that more combinations are tested (E.g., a test can be annotated as transactional and using a cache loader, and the test will be run with every combination of cache loader and transaction manager configured in the suite). The end result here will be a much more robust and well-tested product.


5. Preferred distribution

While we will still upload ZIPs onto SourceForge, we're trying to encourage users to use JBoss Cache using our Maven2 repository (and snapshot repo), to make dependency management easier.

An important point to note is that we've also standardised the groupId and artifactId used to org.jboss.cache and jbosscache-core (or jbosscache-pojo) respectively.


6. JBoss Cache 2.1.0 Alegrias

I had asked for suggestions for naming JBoss Cache 2.1.0 on the dev mail list, and have decided on Alegrias, courtesy of Galder Zamarreno. From Galder's email:

It's a type of very spicy chilli pepper from La Rioja in Spain, the same region from which the best spanish red wine comes.

Alegrias means happiness in plural, but in this case, they're trying to highlight tears of happiness ;)

So with that, I'd like to thank everyone who helped with Habanero and look forward to your participation on Algerias.

Cheers,
Manik Surtani
