PostgreSQL recently published new point releases which fix the usual range of important bugs (data loss/wrong results, etc.) and additionally fix another case of insecure “security definer” functions (the analogon to setuid programs in file system space for SQL functions) (CVE-2007-6600). Please see the complete changes for 8.1.18 (Ubuntu 6.06 LTS), 8.3.8 (Ubuntu 8.04 LTS, 8.10, and 9.04), and 8.4.1 (Ubuntu 9.10). 8.4.1 is already in Ubuntu 9.10 and in my PostgreSQL Backports PPA for Ubuntu 8. ...

It has been broken for two months, since we upgraded to the “new” (not quite any more) gdm in Karmic: But I finally got around to re-doing the gdm patch for supporting a guest session for 2.27. I use it myself a lot for testing stuff with a clean user profile, so I can finally delete my herd of test users again. One known drawback is that the guest session is not currently restricted by AppArmor rules yet. ... Read More
I moved my blog from its old home to my own server, replacing my ancient home page. — Mein Blog ist von seiner alten auf meinen eigenen Server umgezogen, und hat damit auch gleich meine Uralt-Homepage ersetzt.
I often do upstream releases of my upstream projects that I do on Launchpad, mostly for Apport and jockey. But doing this has been quite tedious until now: You have to go to the project page, pick the series (usually “trunk”), create a new release, create a new milestone along the way, then go to “add download file”, and upload your .tar.gz and .tar.gz.asc. Because this is rather inconvenient, I don’t do as many upstream releases as I should. ... Read More
Today I returned from a great mini-vacation (long weekend). My parents and I visited my sister, in-law, niece, and nephew in Bavaria. We don’t see each other very often, it’s always great for me to see my niece and nephew grow, and play with them. The highlight of the vacation was on Sunday, when my father, my in-law, and me went to Insbruck, Austria, on a 5-hour fixed-rope route climbing tour. ... Read More

gvfs: Buh-bye, hal!
3 July 2009

In the merciless vendetta for purging hal we now reached another major milestone: gvfs, GNOME’s file system layer which handles USB storage as well as virtual file systems for libgphoto2 cameras, Bluetooth devices, audio CDs, or ftp/sftp/cifs mounts, is now fully ported to libgudev and doesn’t need hal at all any more. These long nights of porting weren’t in vain, after all \o/. Now I just need to hassle David Zeuthen to apply the patches soon. ... Read More
So far, Apport package hooks were limited to collecting data from the local system. However, a lot of debugging recipes and standard bug triage ping pong involves asking the reporter further questions which need reponses from a human. This can range from a very simple information message box “Now, please plug in the camera which is not detected” until a complex decision tree based on the symptoms the user sees. ... Read More

hal-sectomy continues
3 June 2009

The migration away from hal continues. Yesterday I uploaded new udev-extras and hal packages which move the handling of local device access from hal to /lib/udev/rules.d/70-acl.rules. Note that this temporarily breaks device access to old cameras which don’t speak the standard PTP protocol yet (and aren’t mass-storage). Most devices should work fine, though, please let me know if something fails (ubuntu-bug udev-extras). I started a discussion with upstream about how to migrate the libgphoto bits away from hal to udev rules. ... Read More
This morning I added a test script to the Apport bug patterns. This finally allows you to reliably test a new bug pattern before you actually commit/push it. You can invoke it with either a .crash file, or a Launchpad bug number: `This morning I added a test script to the Apport bug patterns. This finally allows you to reliably test a new bug pattern before you actually commit/push it. You can invoke it with either a . ... Read More
I recently started working on packaging pieces of the new DeviceKit world, which is gradually replacing hal. In particular, DeviceKit-disks and DeviceKit-power are in Karmic now, and gnome-disk-utility and a patches gvfs are in the ubuntu-desktop PPA. A few days ago I wondered what the replacement of hal-setup-keymap would be. This is the bit that makes your laptop’s magic Fn keys work, such as “brightness up”, “next song”, “WWW browser”. I became quite acquainted with this component in the last six months and committed a fair share of fixes to hal-info for those. ... Read More
