Quick news: dpkg, collab-maint, alioth and the future

July 22, 2010 by Raphaël Hertzog

Dpkg got rid of Perl

Let’s start with the interesting part and the great news: dpkg 1.15.8 (to be uploaded soon) will no longer need perl! After my changes to rewrite update-alternatives in C, Guillem recently pushed the rewrite of dpkg-divert/mksplit in C. Please test it out (binary package for i386 or .dsc).

This is rather exciting news for those who would like to use dpkg in embedded contexts. And it’s great to see this completed in time for Squeeze. In Squeeze+1, we might go one step further and merge cdebconf, the C replacement for debconf.

I got rid of some recurring administrative tasks

I have been administrating the Alioth server since its inception (see the announce I sent in 2003) but I’m no longer enjoying the day-to-day administrative work that it represents. That’s why I just retired from the team. We recently recruited Tollef Fog Heen so the number of admins is still the same (that said, Alioth could benefit from some more help, if you’re a DD and interested, drop a mail to admin@alioth.debian.org or come to #alioth).

Same goes for the collab-maint project. I have dealt with hundreds of requests to add new contributors to the project since it’s the central repository where all Debian developers have write access and where they put the VCS for their packages that do not belong to a more specialized team. The new administrator that will approve the requests is Xavier Oswald and he’s doing the work under the umbrella of the New Maintainer’s Front Desk.

The future

I will continue to spend the same amount of time on Debian, the time freed will quickly be reallocated to other Debian and free software related projects. In fact, I even anticipated a bit by launching Flattr FOSS last week but that’s a relatively simple project. 🙂

The other projects that will never all fit in the freed time: I want to spend more time working on dpkg. I do plan to blog more often too, but I’m sure you’ll notice that yourself soon. I would like to see my Debian book translated into English (another post coming on the topic sometimes soon). In my dreams, I could even start yet another software project, I have some ideas that I really would like to see implemented but I don’t see how that could fit in this year’s planning… unless I can convince someone else to implement them! Maybe I should blog about them.

Joining Ubuntu as a Debian developer

July 7, 2010 by Raphaël Hertzog

I’m a Debian developer since 1998 and have been fostering cooperation between Debian and Ubuntu since its inception with various levels of success.

I recently decided to go one step further and join Ubuntu as an official member. I wanted to be able to vote and to promote best cooperation practices from the Ubuntu side as well (and not only in Debian). Joining as a Debian developer should be relatively easy, it is well known in the Debian community that Mark Shuttleworth once said:

Every Debian developer is also an Ubuntu developer, because one way to contribute to Ubuntu is to contribute to Debian.

So I sought to verify that too! Here’s the result.

I prepared my application page collecting 2 testimonials from Lucas Nussbaum and Colin Watson, I registered for the next EMEA membership meeting (which happened yesterday, irc logs here), and I attended. (I just followed the instructions on the wiki)

During the meeting, when it was my turn, I pasted my short introduction and got immediately +1 votes from several board members, they didn’t even want to hear from me, they were already convinced. 🙂 I still responded to a few questions and elaborated on my goals and was promptly accepted even if I made it clear that my technical contributions will continue to be done within Debian.

A few minutes later I was added to the ubuntumembers launchpad group and this morning I followed the instructions to add my feed to Planet Ubuntu and here I am…

The whole process has been very smooth and the meeting shows a very welcoming attitude. Even someone who was denied the Ubuntu member status was cheered for his work and encouraged to try again when he can present some testimonials from other members.

Hello Planet Ubuntu!

Rewriting update-alternatives in C

May 27, 2010 by Raphaël Hertzog

Among the goals listed in dpkg’s roadmap, there’s the C rewrite of the remaining perl scripts provided by the dpkg binary package (dpkg-dev is not concerned, it will remain a collection of perl scripts). Of the remaining scripts, update-alternatives was the largest piece of code (~1100 lines of perl) and I started converting it to C a few weeks ago (based on preliminary work of Guillem). It’s now 2200 lines of C…

Thanks to the relatively extensive test-suite that I wrote last year, I’m relatively confident that this new update-alternatives won’t break your system. That said, it still needs some real-life usage to ensure everything is really ok (and users actively trying to break it are even better). Thus I would be glad if you could try it out ( binary package for i386 or .dsc) and report back to debian-dpkg@lists.debian.org.

The rewrite of the 2 other remaining scripts is almost completed in a branch of Guillem. Hopefully this can be our last project completed in time for Squeeze as far as dpkg goes. It would be a great achievement for people that would like to use dpkg in embedded environments and avoid perl due to its size.

Note: nobody sponsored that work. But it’s not too late 🙂

New source formats allowed in testing/unstable

November 2, 2009 by Raphaël Hertzog

The ftpmasters merged my dak branch last week during their meeting and have enabled the support of new source formats “3.0 (quilt)” and “3.0 (native)” in testing, unstable and testing-proposed-updates. I have uploaded 3 packages using the new formats already: logidee-tools using “3.0 (native)”, quilt and ftplib using “3.0 (quilt)”. The latter is arch any and has been successfully built on all architectures even those that still use an old version of sbuild (it looks like the fears that the old version would not cope with the new format were unfounded). For logidee-tools I built it with “-Zbzip2” in order to use bzip2 compression on the native tarball.

I have updated the wiki page and the release goal page with latest information. Feel free to convert some of your packages to give it a try. For ftplib, it led me to discover a Debian specific patch that I completely missed when I took the package over. This is precisely the kind of benefit that I expect from generalizing this format, it will encourage us to have separate documented patches instead of keeping everything hidden inside the usual .diff.gz. Combined with DEP-3 (patch tagging guidelines), we have a better infrastructure to share our patches with the rest of the free software community.

The next step is to fix all bugs listed here and make dpkg-source use the new source formats by default (#553928). Feel free to help by preparing patches (and offering NMUs), it’s a release goal to have all packages buildable with new source formats.
