Long Overdue Update

  • September 7, 2009
  • Jannis Pohlmann

I haven't posted anything in a while, but I'm not complaining. The last month I've been mostly busy pretending to be busy. Ok, to be honest, that's not entirely true. Over at Xfce, we have achieved a lot in August:

  • We've moved all Xfce repositories (including the goodies) over to Git. Kudos to Brian for doing most of the work.
  • All Xfce translation updates are now submitted via Transifex. Thanks to the Transifex developers for all the support and for being such a friendly bunch. It amazes me that Dimitris, the founder of Indifex, is also active on our translations mailing list to support people!
  • The migration of the Thunar core to GIO is complete and has been merged into the main development branch. The overall delta was 2.9MB, although admittedly, a big part of that is due to the removal of ThunarVFS, so I can only take credit for about 16,000 of the 24,335 insertions and 6,000 of the 41,356 deletions.
  • We've kicked off the Xfce 4.8 development cycle on August 16th. The schedule and all other details are available on the wiki. Xfce 4.8 is scheduled for April 12th, 2010. Expect development releases of the various core components soon!

Other things I've been planning to blog about but didn't have the time to:

  • Samuel is still busy setting up Buildbot. With less time than he had hoped for at hands this might still take a while.
  • I was provided with a free Linutop 2 in June. I'd like to thank the Linutop company again for this gift! So far, I've only found the time to give it a few test boots but I'm planning to set it up as a Xfce test machine soon. Its limited hardware makes it much better platform than my rather powerful laptop and/or virtual machines for testing the speed and memory demand of Xfce.
  • My thesis is progressing slowly. I think I have at least 3/4 finished now. I'll keep you posted about the result. I'm hoping to kick off the six month learning phase for my final exams before October because a friend of mine is already waiting for me. ;)

The new Xfce release manager for users and packagers

  • August 3, 2009
  • Jannis Pohlmann

I deleted the last post about the release manager because due to the high number of changes I made it was soon out of date. So let's get back to the topic again. I'll split it up into two posts: this one which is for users and packagers mostly, and another one directed to developers or, more precisely, maintainers.

Let's start with a simple question (with a long answer): what am I talking about and what is this release manager anyway?

First, a bit of background. At Xfce, we are currently working on improving our infrastructure. We are about to switch to git and along with that, our repository layout will change. Xfce and goodie repositories will no longer be found in separate locations. We thought it would be nice to implement the same layout in other places as well, like Bugzilla and our download archive.

Nick went ahead and enabled so-called bugzilla classifications and used those to resemble the repository layout on bugzilla.xfce.org.

That still left us with separate download archives for core Xfce, goodies and other stuff. For goodies, we had a very simple release manager web application written in PHP that uploaded tarballs to http://goodies.xfce.org/releases/ and was able to send release announcements to mailing lists. The design however was very limited. For Xfce releases we had nothing like that. Uploading and copying tarballs around manually for each release was what we had to do.

And this is where the new all-in-one release manager comes into play. It's called Moka, it is written in Ruby using Sinatra, ERB and JSON and the source code can be found here.

For you as a user or packager, it does two things:

  1. it uploads all (core and goodies) tarballs to http://archive.xfce.org which uses the same layout as our future git repositories and bugzilla
  2. it pushes release announcements out to mailinglists, Atom feeds, identi.ca and Twitter.

Download archive

The layout is described in the archive reorganization section of this mail. It contains releases of all projects, be they goodies, core components or something else. Again, we use classifications like apps, libs, bindings or core to add semantics the archive layout.

All tarballs are accompanied by an MD5 and SHA1 checksum file. In the future, we're hoping to also support PGP signing of tarballs. So, for the 0.4.0 release of terminal, you'll get these three files:

  • Terminal-0.4.0.tar.bz2
  • Terminal-0.4.0.tar.bz2.md5
  • Terminal-0.4.0.tar.bz2.sha1

If you download one of the checksum files along with the tarball you can verify the download went fine with md5sum -c Terminal-0.4.0.tar.bz2.md5 or sha1sum -c Terminal-0.4.0.tar.bz2.sha1.

Announcements

Release announcements are sent to different mailinglists (almost always to xfce@xfce.org, so you're on the safe side subscribing to that one), identi.ca/xfce and twitter.com/xfceofficial.

The status updates on identi.ca/xfce and twitter.com/xfceofficial use the following format:

terminal 0.4.0 released! http://releases.xfce.org/feeds/project/terminal !Xfce

Atom feeds for all projects are available on http://releases.xfce.org/feeds/project/. There also is a dedicated feed for bundle releases of Xfce core components available on http://releases.xfce.org/feeds/collection/xfce. These feeds provide more information about the releases than the posts on identi.ca or Twitter do. There's no central feed for all releases yet, but you can as well subscribe to the feeds offered to you by identi.ca or Twitter.

Mailinglist announcements and feed posts use the same format. Here's a good example for a project release announcement:

xfce4-power-manager 0.8.3 is now available for download from

What is xfce4-power-manager?
============================

This software is a power manager for the Xfce desktop, Xfce power
manager manages the power sources on the computer and the devices that
can be controlled to reduce their power consumption (such as LCD
brightness level, monitor sleep, CPU frequency scaling). In addition,
xfce4-power-manager provides a set of freedesktop-compliant DBus
interfaces to inform other applications about current power level so
that they can adjust their power consumption, and it provides the
inhibit interface which allows applications to prevent automatic sleep
actions via the power manager; as an example, the operating system’s
package manager should make use of this interface while it is performing
update operations.

Release notes for 0.8.3
=======================

- Provides more standard org.fd.PowerManagement DBus methods and signal
(bug #5569).
- Make it possible to compile without network manager support.
- Add never show icon to the system tray configuration (bug #5613).
- Fix a typo that prevents from getting the correct critical
configuration (bug #5619).
- Use Gtk as a popup indicator to show the brightness level as the cairo
seems to be 
  problematic on some hardware. (bug #5544 #5632).
- Better alignement in the interface file, worked by Josef Havran.

This is what the new release manager does for you. I think or rather hope that it provides an efficient way to to keep you posted about what's going on. And hopefully, all of you enjoy our efforts to unify our infrastructure and by that make things more transparent. As always, if you have any ideas for improvements, let us know!

I'm on Twitter now. My username is jannispohlmann. I guess I'll be microblogging about software (Xfce!) mostly and post the personal stuff on Facebook were only my friends can read it (hopefully). Follow me if you're interested.

Edit: Ok, I'm also on identi.ca now: identi.ca profile. I'll be forwarding anything from ident.ca to twitter, so you can follow me wherever you want.
