dotnet

  • Worked on the new .NET snap:
    • Worked on setting up the snap hooks to install the latest SDK on first install and update components on subsequent refreshes using the installer tool shipped in the snap (PR #5).
    • Set up the install command so that only one version of the runtime/SDK is kept per major/feature band (PR #6).
    • Started adding unit tests to the installer project to get some coverage going (PR #7).
    • Set up a CI pipeline to run these tests and publish coverage information to a GitHub Pages website.
    • Refactored some components of the installer project into dependency-injected services to achieve better code testability (PR #8)
  • Experimented building current snapcraft.yaml from Microsoft for the dotnet-sdk snap.
  • Attended weekly .NET partners sync meeting

Misc

Distro

  • Final changes before openssl 3.0.13 was uploaded; thanks @tobhe and @schopin in particular
  • Triggering tests again dozen of times, targetting tests with only armhf failures as soon as logs say “badpkg” or something like that
  • Doing the same for arm64 and ppc64el because queues are empty

armhf Y2038 support (a.k.a armhf 64-bit time_t)

  • Went over a list of packages needing merges in Ubuntu and dumped/diffed the ABI for more than a dozen in order to know if we can skip merging them (around 10 could be skipped)

proposed migration

  • freetype: only failing armhf autopkgtests. I checked some of the failures. All of those were caused by badpkg. So these test needs to run against all-proposed (due to the time_t transition).

64-bit time_t transition

  • Sync zbar 0.23.93-4 to get a rebuild against libv4l-0t
  • Retried mjpegtools 1:2.1.0+debian-8.1
  • gr-fosphor, gr-iqbal, and gr-radar → python3-pyqt6 (pyqt6) → retried since libqt6widgets6 (qt6-base) → waits on qt6-webengine rebuild
  • Uploaded ucommon 7.0.1-0.2ubuntu3 to fix symbols
  • Please remove minizip
  • Uploaded mapnik 3.1.0+ds-7ubuntu1 to use scons from the Debian package (for Python 3.12 support)
  • libapache2-mod-tile → mapnik
  • Uploaded poppler 24.02.0-1ubuntu8 to rename libraries for 64-bit time_t transition
  • sndobj 2.6.7+ds1-4 for Python 3.12 fix
  • Uploaded polylib 5.22.5-4.2+dfsg to Debian
  • Synced pacman-package-manager 6.0.2-6

Distro

  • cryptsetup & jq migration. Retry the tests and they are waiting the results and openssl to be migrated first.
  • Rename the bamf library name for time_t transition. Ubuntu version is newer than Debian, so the time_t change is not synced.
  • Rename libcupsfilter library name for time_t transition. The cups package is split in Ubuntu, so the time_t change is not synced.
  • Continue debugging kmod on armhf after time_t changes. The test failures still exist and are suspicious.

auto upgrade testing

  • PR to support double LTS upgrades
  • Opened bug regarding apt-xapian-index crash.

autopkgtest-cloud

  • Investigated an issue with noble images being old on LXD armhf remote, and starting to behave strangely. As they’re not updated regularly, we split the work in the team to update all the armhf LXD remotes with both a new autopkgtest branch supporting deb822, and updated the noble image, in the hope of having things more stable over the week-end
  • Lots of issue during the week-end and beginning of the week, but everything was stabilized by Tuesday afternoon.
  • Added 14 new armhf workers in bos03, along with all the issues that needed to be addressed, like disk device block name that changed, network device changed, LXD images building issues, etc… Throughput for armhf has now increased consequently, and is being much more stable.
  • Couple of MP opened and reviewed

+1

  • Investigated gvmd dependency issue related to time_t transition. Thanks @bdrung for the upload :slight_smile:

  • Fixed startup of software-properties
  • Some grub review stuff
  • Seriously extended my dose-distcheck human report script so that you see conflicting chains, have results for armhf, as well as binary uninstallability.
  • Used report output to fix some time_t issues on armhf by uploading rebuilds :slight_smile:

glibc:

  • AppArmor vs glibc:
    • patch sent upstream to mark tests as unsupported if running when apparmor userns mitigation is enabled
    • tweaked autopkgtests to disable userns mitigation entirely. We want those tests to run!
  • filed a bug to track a ppc64el test regression
  • Conformance tests in t64

misc:

  • gtk+3.0: fixed FTBFS due to implicit function declaration (t64 transition)
  • qtwebengine-opensource-src: fix Py 3.12 FTBFS (t64 transition)
  • GH work
  • openssl upload.
