As you might or might not know, the XMPP Standards Foundation has been accepted as a mentoring organization for the 2010 edition of the Google Summer of Code. Amongst others, specific project proposals for the IgniteRealtime community are available. They are being discussed in GSoC 2010 Projects. The deadline for student applications is next Friday (April 9th, 19:00  UTC). If you are interested, head over to the XSF wiki for  more information!

We have just released version 1.2.1 of Tinder. This version is a bugfix release, that improvement the AbstractComponent implementation that was added in version 1.2.0.

We are happy to announce that the clustering plugin is now available as an open source plugin. The clustering plugin adds support for running multiple redundant Openfire servers together in a cluster.  By running Openfire in a cluster, you can distribute the load amongst a number of servers, as well as having some form of redundancy in the event that one of your servers dies.

By making this functionality open source we now made 100% of the old Enterprise plugin open source. The reason why the clustering plugin came last is that it relies on Oracle Coherence, that is a commercial product, so to make it open source was a little tricky. At the end what we did was to open source our implemented functionality but to use this plugin you will need to get a valid Oracle Coherence license. The readme file explains the steps to follow to install this plugin. Moreover, it also explains how to setup your environment if you plan to develop new versions of the plugin.

Have fun,

We've just released a new project, named Tinder. Tinder is a new Java based XMPP library, providing an implementation for XMPP stanzas and components.

Tinders origins lie in code that's shared between Jive Software's Openfire and Whack implementations. The implementation that's provided in Tinder hasn't been written again from scratch. Instead, code has been moved from the original projects into Tinder, preserving al of the existing features and functionality. Most of the code that's now in Tinder is based on the org.xmpp package implementation that previously existed in Openfire and Whack. This is the code that defines classes such as Packet, JID, IQ, Component and their extensions. Additionally, some multi-purpose code (such as the DataForm and Result Set Management implementations have been moved to Tinder as well.

Why a new project?

Parts of the code of Openfire are useful in other contexts than that of an XMPP server implementation. Developers might, for instance, want to use the XMPP stanza implementation within other projects. Having to include Openfire as a dependency of such a project is quite a bit of overkill. In such an example, it would be useful to have a small project that you can include, that offers you a lightweight XMPP object implementation, without the rest of the features that Openfire offers. Enter Tinder. Tinder will allow developers to re-use parts of Openfire, without having to include Openfire itself.

There's other benefits to Tinder though:

Tinder will replace some most of the duplicate code that's currently shared in Openfire, Whack and ConnectionManager projects. Removing duplicate code will make it easier to maintain and develop these projects. By delegating the implementation and maintenance of the low-level XMPP implementation, Openfire, Whack and other developers will be able to focus on the development that adds value to their project.

On the flip-side of that medal, you can argue that the 'core' code that will make up Tinder deserves a bit of dedicated development attention (unit tests, bug-tracking, stuff like that). This would benefit any attempt to really fine-tune the code, for example for high-performance tuning. Currently, the code is a bit put in the shadows of the other projects (of which they are part of).

So, will this replace Smack (the library that provides the base of Spark)?

No, definitely not. Smack offers a full-fledged XMPP client implementation, while Tinder only defines some XMPP building blocks. Tinder provides some basic objects on which a client library such as Smack could be build. However, Smack does not share the same code base as Openfire and Whack do. It's therefor unlikely that Tinder and Smack will be merged in the foreseeable future - there's simply to much difference.

What's next?

We've wrapped up a initial roadmap, in which we capture the first steps of the development of Tinder. As always, you're invited to contribute. We're looking forward to hear your suggestions, thoughts and ideas. If you're interested, you can find more information on the new Tinder-related community space and project page that have been opened on IgniteRealtime.org.

We've released the first beta of Smack 3.1.0. Although it's been about a year since the last release, this version is jam-packed with great new features and bug fixes. Check out the changelog for full details.

We expect the beta process on the release to be relatively quick, but much will depend on the stability feedback we get. There are also a few last changes that we're looking to get in before the final release.

Whack 1.0 has been released. Whack is our Open Source XMPP (Jabber) component library for XMPP components. External components are processes that run outside of the Openfire's process but can connect to the server to register new XMPP service. Whack is an implementation of XEP-0114: Jabber Component Protocol.

Unlike the other igniterealtime products, Whack followed a different evolution path. We started coding Whack around November 2004 and after a few months it was operational. Openfire and Whack share the same component's API so around 2005 we were able to run Fastpath as an internal component (i.e. running in the Openfire's process) or just move it as an external component using Whack. It was impressive seeing the same code running as internal and external. Since then Whack continued to evolve but always at a very slow pace. Whack was always stable in each step but it was just not ready for prime time. We wanted to keep adding more things to it to reach a 1.0 release. Since our collaboration software Clearspace uses Whack to integrate with Openfire we needed to push the boundaries of Whack once again and I'm happy to say that we now reached the 1.0 release. And that is why we decided to make a public release in 2008 after 4 years of continuous but slow growth.

A few months ago we also released a new product called SparkWeb. SparkWeb is our Open Source web-based IM client. SparkWeb is based on XIFF just like Spark is based on Smack. Today we updated the products page to list SparkWeb as an official product. Welcome SparkWeb! The family has grown a little bit now.

You can get Whack from here. Questions could be posted to the Whack forum.

SparkWeb can be downloaded from here. If you want to build from the source code you can read the Getting and Building SparkWeb document.

It took us some time but we finally made it. The Enterprise Edition plugin has been broken into smaller open source plugins as mentioned in the Turning Openfire Enterprise into an open source product blog post.

The new plugins can be found here:

• Monitoring Service (released on Apr 24, 2008)

• Fastpath Service (released on Apr 24, 2008)

• Clustering Plugin (released on May 6, 2008)

• Client Control (released on May 13, 2008)

With these new plugins the total number of official open source plugins is now 17. If we add the clustering plugin that is commercial and the 3 beta plugins that includes the popular Red5 plugin the total number of plugins comes up to 21. Finally, more plugins can be found in the Non-Jive Openfire Plugins document.

Enjoy,

The Openfire Team
