I’m nominated for Top Contributor in 2011 Eclipse Awards

To be honest I haven’t been fallowing anything connected with Eclipse Community Awards, because I was thinking that this isn’t for me as em I a humble EGit commiter. But is seams that some one has different opinion on this, because I was nominated …

You can imagine my surprise when I got an email with information that I’m nominated for Top Contributor. I was totally shock! and can’t believe in this. But then I check Eclipse Community Awards Bulletin and I saw my name on the list of nominated contributors … I believed that this it is true.

I’m honored, I’m truly honored, no mater what the final results would be I’m honored with this nomination!

Finally I want to encourage you to take part in voting for Eclipse Community Awards, especially I encourage to vote on EGit project with was nominated in category: Most Innovative New Feature or Eclipse Project 😉

Show non-workspace resources in Git Change Set

Synchronize view in EGit doesn’t show non-workspace files from its very beginning. This issue seams to be very complicated and also it seams to require lots of hacking on team framework and eclipse API.

Few days ago Ilya Ivanov from Intland pushed into our gerrit a patch that should fix this issue. I was very surprised that this change is so small and simple. It only works partially because the compare editor cannot be launched for non-workspace files. In my opinion this patch cannot be merge into master branch without this core functionality, so today I spent about 3 or 4 hours hacking on that topic … and here are results:

As you can see, there is master pom file (with isn’t imported into eclipse workspace) in synchronize view and on the left hand side there is a compare  editor for it, showing what was changed ;>

Currently both patches are waiting for review in gerrit, but I think that they will be merged into master soon 😉

EGit hackfest @ SAP Walldorf

Last week I spent in Walldorf (Germany) at EGit hackfest. I want to attend on all sessions therefore I’ve decided to go there day before and leave Walldorf day after event. Therefore I had some time that I can spent on short tours in Walldorf and Frankfurt. Here is a short summarization things that we manage to achieve during this time in case of synchronize view in EGit.

With Christian Halstrick we manage to speed up synchronization operation. Our starting point was comparing branch stable-0.7 against stable-0.10 from EGit repository with at the beginning takes around 2 minutes. Then using yourkit profiler we manage to reduce synchronization time down to less then 20 seconds on the same data set! The first set of patches that gives most acceleration were already merged into master and are available in latest nightly build of EGit, but there are also some open change sets in gerrit pending for review that should give some performance boost. Even with this improvements synchronization on some large repositories can take more then 5 minures, therefore this topic is still open for me and I’ll continue to hacking on it in feature. Currently one of the slowest part is mapping path of file/folder from git into eclipse’s workspace resource, but this should be improved by new implementation of IWorkspaceRoot.getFileForLocation()/IWorkspaceRoot.getContainerForLocation() in Eclipse 3.7 ;>

Second task that I manage to start working on during hack sessions is supporting context menu action in synchronization. I didn’t finish it but most of code is currently written. I only need to improve some things and test it. I think that in week or two this change should appear in gerrit.

This was great opportunity for meet persons that I only know from mailing list or code reviews in gerrit, especially to meet Matthias Sohn and Stefan Lay 😉 and also rest of EGit team members ;>

I want to thanks Matthias Sohn for organizing such great event and SAP for hosting it!. Many thanks also for my employer NCDC for refunding me part of my trip.

Java4People 2011 – call for papers!

Java4People is a free polish conference organized in Szczecin (Poland) by and for Java enthusiasts. We already have had two editions in 2008 and 2009, now it is time to launch call for papers for upcoming 2011 edition.

The main topic of this edition is “JVM languages” and everything connected with it (frameworks, IDEs, etc.), but if you have an interesting presentation about other topic connected with Java don’t hesitate to share it with us!

From my point of view I would like to hear about:

and of course about web or application frameworks’ that was build on top of those languages.

We are open for any propositions, if you have one that you would like to present on Java4People don’t hesitate to contact me (dariusz < a t > luksza < dot > org) or leader of Szczecin Java User Group Leszek Gruchala (leszek < a t > gruchala < dot > eu).

Rebase support in EGit

Thanks to Mathias Kinzler EGit have initial support for rebasing. Currently only the simple scenario is supported, when there are no conflicts between actual and given branch. Currently the only place from with rebase action can be launched is in Git Repositories view, the ‘Rebase’ option is available on each branch node for given repository.

If you want to test this new feature you should install EGit for ours “Bleeding Edge Builds” update site.
