My Free Software Activities in April 2016

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

I handled a new LTS sponsor that wanted to see wheezy keep supporting armel and armhf. This was not part of our initial plans (set during last Debconf) and I thus mailed all teams that were impacted if we were to collectively decide that it was OK to support those architectures. While I was hoping to get a clear answer rather quickly, it turns out that we never managed to get an answer to the question from all parties. Instead the discussion drifted on the more general topic of how we handle sponsorship/funding in the LTS project.

Fortunately, the buildd maintainers said they were OK with this and the ftpmasters had no objections, and they both implicitly enacted the decision: Ansgar Burchardt kept the armel/armhf architectures in the wheezy/updates suite when he handled the switch to the LTS team, and Aurélien Jarno also configured wanna-build to keep building armel/armhf for the suite. The DSA team did not confirm that this change was not interfering with one of their plans to decommission some hardware. Build daemons are a shared resource anyway and a single server is likely to handle builds for multiple releases.

DebConf 16

This month I registered for DebConf 16 and submitted multiple talk/BoF proposals:

  • Kali Linux’s Experience of a Debian Derivative Based on Testing (Talk)
  • 2 Years of Work of Paid Contributors in the Debian LTS Project (Talk)
  • Using Debian Money to Fund Debian Projects (BoF)

I want to share the setup we use in Kali as it can be useful for other derivatives and also for Debian itself to help smooth the relationship with derivatives.

I also want to open again the debate on the usage of money within Debian. It’s a hard topic but we should really strive to take some official position on what’s possible and what’s not possible. With Debian LTS and its sponsorship we have seen that we can use money to some extent without hurting the Debian project as a whole. Can this be transposed to other teams or projects? What are the limits? Can we define a framework and clear rules? I expect the discussion to be very interesting in the BoF. Mehdi Dogguy has agreed to handle this BoF with me.

Packaging

Django. I uploaded 1.8.12 to jessie-backports and 1.9.5 to unstable. I filed two upstream bugs (26473 and 26474) for two problems spotted by lintian.

Unfortunately, when I wanted to upload it to unstable, the test suite did not ran. I pinned this down to a sqlite regression. Chris Lamb filed #820225 and I contacted the SQLite and Django upstream developers by email to point them to this issue. I helped the SQLite upstream author (Richard Hipp) to reproduce the issue and he was quick to provide a patch which landed in 3.12.1.

Later in the month I made another upload to fix an upgrade bug (#821789).

GNOME 3.20. As for each new version, I updated gnome-shell-timer to ensure it works with the new GNOME. This time I spent a bit more time to fix a regression (805347) that dates back to a while and that would never be fixed otherwise since the upstream author orphaned this extension (as he no longer uses GNOME).

I have also been bitten by display problems where accented characters would be displayed below the character that follows. With the help of members of the GNOME team, we found out that this was a problem specific to the cantarell font and was only triggered with Harfbuzz 1.2. This is tracked in Debian with #822682 on harfbuzz and #822762 in fonts-cantarell. There’s a new upstream release (with the fix) ready to be packaged but unfortunately it is blocked by the lack of a recent fontforge in Debian. I thus mailed debian-mentors in the hope to find volunteers to help the pkg-fonts team to package a newer version…

Misc Debian/Kali work

Distro Tracker. I started to mentor Vladimir Likic who contacted me because he wants to contribute to Distro Tracker. I helped him to setup his development environment and we fixed a few issues in the process.

Bug reports. I filed many bug reports, most of them due to my work on Kali:

  • #820288: a request to keep the wordpress package installable in older releases (due to renaming of many php packages)
  • #820660: request support of by-hash indices in reprepro
  • #820867: possibility to apply overrides on already installed packages in reprepro
  • #821070: jessie to stretch upgrade problem with samba-vfs-modules
  • #822157: python-future hides and breaks python-configparser
  • #822669: dh_installinit inserts useless autoscript for System V init script when package doesn’t contain any
  • #822670: dh-systemd should be merged into debhelper, we have systemd by default and debhelper should have proper support for it by default

I also investigated #819958 that was affecting testing since it has been reported to Kali as well. And I made an NMU of dh-make-golang to fix #819472 that I reported earlier.

My Free Software Activities in December 2015

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

This month I have been paid to work 21.25 hours on Debian LTS. During this time I worked on the following things:

  • Sent a first patch and later an updated patch to modify DAK so that it can send the accept/reject mails to the signer of the upload instead of the maintainer. Details in #796784.
  • Uploaded MySQL 5.5 compabitility fixes for phpmyadmin and postfix-policyd so that we could release MySQL 5.5 as an upgrade option MySQL 5.1 (see DLA 359-1).
  • Released DLA 361-1 on bouncycastle after having gotten the green light from upstream.
  • Released DLA 362-1 on dhcpd fixing three CVE.
  • Released DLA 366-1 on arts fixing one CVE.
  • Released DLA 367-1 on kdelibs fixing one CVE.
  • Handled the LTS frontdesk for a whole week.
  • Sponsored the upload of foomatic-filters for DLA 371-1.
  • Filed #808256 and #808257 to get libnsbmp/libnsgif removed. Both packages had recent CVE and were sitting unused in Debian since their introduction 6 years ago…
  • Released DLA 372-1 announcing the end of support of virtualbox-ose.
  • Updated git repository of debian-security-support to account for the former change and also took care of a few pending issues.
  • Released DLA 376-1 on mono to fix one CVE.
  • Added some initial DEP-8 tests to python-django that will help to ensure that a security update doesn’t break the package.

Distro Tracker

I put a big focus on tracker.debian.org work this month. I completed the switch of the mail interface from packages.qa.debian.org to tracker.debian.org and I announced the change on debian-devel-announce.

The changes resulted in a few problems that I quickly fixed (like #807073) and some other failures seen only by me and that were generated by weird spam messages (did you know that a subject can’t have a newline character but that it can be encoded and folded over multiple lines?).

Related to that I fixed some services so that they send their mails to tracker.debian.org directly instead of relying on the old emails (they get forwarded for now but it would be nice to be able to get rid of that forward). I updated (with the help of Lucas Nussbaum) the service that forwards the Launchpad bugs to the tracker, I sent a patch to update the @packages.debian.org aliases (not yet applied), I updated the configuration of all git commit notice scripts in the Alioth collab-maint and python-modules project (many remain to be done). I asked Ubuntu’s Merge-O-Matic to use the new emails as well (see LP 1525497). DAK and the Debian BTS still have to be updated, as of yet nobody reacted to my announce… last but not least I updated many wiki pages which duplicated the instructions to setup the commit notice sent to the PTS.

While on a good track I opted to tackle the long-standing RC bug that was plaguing tracker.debian.org (#789183), so I updated the codebase to rely on Twitter’s bootstrap v4 instead of v2. I had to switch to something else for the icons since glyphicons is no longer provided as part of bootstrap and the actual license for the standalone version was not suitable for use. I opted for Github’s Octicons. I made numerous little improvements while doing that (closing some bugs in the process) and I believe that the result is more pleasant to use.

I also did a lot of bug triage and fixed a few small issues like the incomplete architecture list (#793547), or fixing a page used only by people with javascript disabled that was not working. Or the invalid links for packages still using CVS (ugh, see #561228).

Misc packaging

Django. After having added DEP-8 tests (as part of my LTS work, see above), I discovered that the current version in unstable did not pass its test suite… so I filed the issue upstream (ticket 26016) and added the corresponding patch. And I encouraged others to update python-bcrypt in Debian to a newer version that would have worked with Django 1.9 (see #803096). I also fixed another small issue in Django (see ticket 26017 with my pull request that got accepted).

I asked the release managers to consider accepting the latest 1.7.x version in jessie (see #807654) but I have gotten zero answer so far. And I’m not the only one waiting an answer. It’s a bit of a sad situation… we still have a few weeks until the next point release but for once I do it in advance and I would love to have timely feedback.

Last but not least, I started the maintaining the current LTS release (1.8.x) in jessie-backports.

Tryton. I upgraded to Tryton 3.8 and discovered an issue that I filed in #806781. I sponsored 5 new tryton modules for Matthias Behrle (who is DM) as well as one security upload (for CVE-2015-0861).

Debian Handbook. I uploaded a new version to Debian Unstable and requested (to the release managers) the permission to upload a backport of it to jessie so that jessie has a version of the package that documents jessie and not wheezy… contrary to my other Django request, this one should be non-controversial but I also have had zero answer so far, see #807515.

Misc. I filed #808583 when sbuild stopped working with Perl 5.22. I handled #807860 on publican, I found the corresponding upstream ticket and discovered a work around with the help of upstream (see here).

Kali related work

I reported a bug to #debian-apt about apt miscalculating download size (ending up with 18 EB!) which resulted in a fix here in version 1.1.4. Installing a meta-package that needed more than 2GB was no longer possible without this fix and we have a kali-linux-all metapackage in that situation that gets regularly installed in a Jenkins test.

I added captcha support to Distro Tracker and enabled this feature on pkg.kali.org.

I filed #808863 against uhd-host because it was not possible to install the package in a systemd-nspawn’s managed chroot where /proc is read-only. And we started using this to test dist-upgrade from one version of Kali to the next…

My Free Software Activities in November 2015

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

This month I have been paid to work 21.25 hours on Debian LTS. During this time I worked on the following things:

  • From November 2nd to November 8th, I was handling the LTS frontdesk, triaging new CVE, filing bugs, and ensuring timely answers on the mailing list. I pushed 26 commits to the security tracker. While investigating CVE-2015-7183 I discovered more embedded copies of nspr (which resulted in #804058). I also commented on the upstream fix for CVE-2015-5602 which looked like insufficient.
  • Prepared and released DLA-339-1 on libhtml-scrubber-perl fixing one CVE.
  • Prepared and released DLA-350-1 on eglibc with a non-trivial backport fixing one CVE.
  • Prepared and released DLA-353-1 on imagemagick fixing two security issues without CVE yet (and marking one as not-affecting squeeze).
  • Added a third patch after review by the upstream author on my still pending bouncycastle update. The upstream author asked me to further defer the update as they have some related fixes coming up.
  • I did preparatory work for DLA-352-1 by identifying the upstream commits that fixed the security issue.
  • I spent some time checking issues that have been assigned for a long time without any visible progress being made in the hope to unblock them (libvncserver, pound, quassel).

The Debian Administrator’s Handbook

Now that the English version has been finalized for Debian 8 Jessie (I uploaded the package to Debian Unstable), I concentrated my efforts on the French version. The book has been fully translated and we’re now finalizing the print version that Eyrolles will again edit.

Paris Open Source Summit

On November 18th and 19th, I was in Paris for the Paris Open Source Summit. I helped to hold a booth for Debian France during two days (with the help of François-Régis and several others).

François Vuillemin, Juliette Belin and Raphaël Hertzog

On the booth, we had the visit of Juliette Belin who created the theme and the artwork of Debian 8 Jessie. We lacked goodies but we organized a lottery to win 12 copies of my French book.

Debian packaging work

Django. After two weeks of preparation for revers dependencies, I uploaded Django 1.8 to unstable and raised the severity of remaining bugs. Later I uploaded a new upstream point release (1.8.6). I also handled a release critical bug first by opening a ticket upstream and then by writing a patch and submitting it upstream. I uploaded 1.8.7-2 to Debian with my patch.

I also submittted another small fix which has been rejected because the manual page is generated via Sphinx and I thus had to file a bug against Sphinx (which I did). A work-around has been found in the mean time.

apt-xapian-index NMU. A long time ago, I filed a release critical bug against that package (#793681) but the maintainer did not handle it. Fortunately Sven Joachim prepared an NMU and I just uploaded his work. This resulted in another problem due bash-completion changes that Sven promptly fixed and I uploaded a second NMU a few days later.

Gnome-shell-timer. I forwarded #805347 to gnome-shell-timer issue #29 but gnome-shell-timer is abandoned upstream. On a suggestion of Paul Wise, I tried to get this nice extension integrated into gnome-shell-extensions but the request has been turned down. Is there anyone with javascript skills who would like to adopt this project as an upstream developer? It’s a low maintenance project with a decent and loyal user base.

Misc. I fixed bug #804763 in zim which was the result of a bad Debian-specific patch.
I sponsored pylint-plugin-utils_0.2.3-2.dsc for Joseph Herlant to fix a release critical bug. I filed 806237 against lintian. I filed more tickets upstream, related to my Kali packaging work: one against sddm, one against john

Other Debian-related work

Distro-Tracker. I finally merged the work of Orestis Ioannou on bug #756766 which added the possibility to browse old news of each package.

Debian Installer. I implemented two small features that we wanted in Kali: I fixed #647405 to have a way to disable “deb-src” lines in generated sources.list files. I also filed #805291 to see how to allow kernel command line preseeding to override initrd preseeding… the fix is trivial and it works in Kali. I just have to commit it in Debian, I was hoping to get an ack from someone in charge before doing it.

My Free Software Activities in October 2015

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donators (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

This month I have been paid to work 13.25 hours on Debian LTS. During this time I worked on the following things:

  • I prepared and released DLA 330-1 fixing two CVE on unzip.
  • I prepared a bouncycastle update fixing CVE-2015-7940 (after having requested that CVE assignment since nobody had done it yet) but I have not yet released the corresponding DLA yet since I’m waiting for a review by the upstream author. This is hairy cryptographic Java code that was non-trivial to backport and I’d rather make sure that I do not mess anything. The patches are available in the bug report #802671 that I opened.
  • I tested the update to MySQL 5.5 with multiple packages and sent back my findings to the debian-lts mailing list.

I also started a conversation about what paid contributors could work on if they have some spare cycle as the current funding level might allow us to invest some time on work outside of just plain security updates.

The Debian Administrator’s Handbook

I spent quite some time finalizing the Jessie book update, both for the content and for the layout of the printed book.

Debian Handbook: cover of the jessie edition

Misc Debian work

GNOME 3.18. I uploaded a new gnome-shell-timer working with GNOME Shell 3.18 and I filed bugs #800660 and #802480 about an annoying gnome-keyring regression… I did multiple test rounds with the Debian maintainers (Dmitry Shachnev, kudos to him!) and the upstream developers (see here and here). Apart from those regressions, I like GNOME 3.18!

Python-modules team migration to Git. After the Git migration, and since the team policy now imposes usage of git-dpm on all members, I made some tries with it on the python-django package while pushing version 1.8.5 to experimental. And the least I can say is that I’m not pleased with the result. I thus filed 3 bugs summarizing the problems I have with git-dpm: #801666 (no way to set the upstream branch names from within the repository), #801667 (no clean way to merge between packaging branches), #801668 (does not create upstream tag immediately on tarball import). That is on top of other randomly stupid bugs that were already reported like #801548 (does not work with perfectly valid pre-existing upstream tags).

Django packaging. I filed bugs on all packages build-depending on python-django that fail to build with Django 1.8 and informed them that I would upload Django 1.8 to unstable in early November (it’s done already). Then I fixed python-django-jsonfield myself since Distro Tracker relies on this package.

Following this small mass-bug filing, I filed a wishlist bug on devscripts to improve the “mass-bug” helper script (see #801926). And since I used “ratt” to rebuild the packages, I filed a wishlist issue on this new tool as well.

Tryton 3.6 upgrade. I upgraded my own Tryton installation to version 3.6 and filed bug #803066 because the SysV init script was not working properly. That also reminded me that the DD process of Matthias Behrle (the tryton package maintainer) was stalled due to a bug in the NM infrastructure so I pinged the NM team and we sorted out a way for me to advocate him and get his process going…

Distro Tracker. I continued my work to refactor the way we handle incoming mail processing (branch people/hertzog/mailprocessing). It’s now mostly finished and I need to deploy it in a test environment before being able to roll it out on tracker.debian.org.

Thanks
