autopkgtest

  • After testing s390x instance creation, pinged IS regarding restarting neutron for s0lp4. RT 155441 is the ticket about getting this fixed for reals.
  • Merged @andersson123’s MP which prevents duplicate test combinations from being submitted.

  • Submitted an MP with the change I deployed in production.
  • Reported bug 2028796 regarding the error queueing autopkgtests encountered by an Ubuntu Developer.
  • Reported bug 2028801 regarding the rejection message saying the test was queued when it was in fact running.
  • Stopped running Kinetic autopkgtests as it is EoL. Removed Kinetic autopkgtest images from swift.

Ubuntu

  • Submitted an RT regarding the Ubuntu release KPI collector not being able to communicate with any cdimage servers via rsync any more.
  • Submitted a firewall change giving the Ubuntu KPI server access back to the cdimage mirror servers which then fixes our cdimage size and age KPIs.
  • Reported an issue regarding the timers for the metrics.
  • Submitted a PR which adds support for getting CD image size and age for Ubuntu Studio in the ubuntu-release metrics.
  • Updated the cnf extractor for the EoL of Kinetic.

OpenJDK technical debt

  • Investigated an intermittent test failure (seen only in the CI) and proposed to not skip the failing test.

openjdk-fips

  • Autopkgtests - added sanity FIPS support tests (MR)

Proposed migrations

  • Worked on two proposed migration bugs
    1. python-coverage vs. setuptools
    2. casper vs. systemd

Fixes came in from upstream debian for both. So, I didn’t have to do much. However, these two issues helped me with a nice practical introduction to proposed migrations and autopkgtests.

Misc

  • Adoptium Steering Committee meeting
  • OpenJDK FIPS code review
  • More visa paperwork :sweat:

subiquity

  • brainstormed about the dependency of the source model on other models

distro

  • reworked MP for dbus 1.14.8-2 to address comments. Sponsored by @schopin, thanks!
  • Investigated dbus autopkgtest failures on i386 (was a good opportunity to learn about i386 tooling in Ubuntu). Turned out to be an infrastructure issue. Passed after a retry.

+1 rotation

  • retried python-test-stages on all arches to unblock tox 4.4 - which has now migrated
  • zulucrypt - investigated autopkgtest failures on some types of test beds. Turned out that for some reason, zulucrypt attempts to setuid(SUDO_UID) when the SUDO_UID variable is defined - which causes permission denied errors in the test-suite. Opened a bug report upstream to get the root cause addressed. Worked around the issue in autopkgtest by unsetting the SUDO_UID variable (sponsored by @slyon, thanks!) and forwarded to Debian. The package migrated. See https://launchpad.net/bugs/2023614
  • python-pytest-trio: retried autopkgtest with additional triggers to allow it to migrate alongside python-trio. Migrated.
  • onednn: investigated arm64 build failure with GCC-13. There is an existing bug report upstream and the issue was addressed in onednn 3.1. I backported the changes to onednn 2.7 in Ubuntu (this was sponsored by @tsimonq2, thanks!) and forwarded the delta to Debian. The package migrated. See https://launchpad.net/bugs/2028759

  • Slow week, medical issues
  • Working on udev rule replacements; libcamera relatively simple, GPIO/I2C/SPI simple, UARTs proving a bit harder
  • Reviewed @bdrung’s changes for initramfs-tools, and did some timings on Pi 4 and Pi Zero 2
  • Finished u-boot merge with some extra patches from @xypron (LP: #2027789)
  • Still writing second article on the state of the various desktop flavours on the Pi (if anyone’s wondering about the delay I wound up testing several I hadn’t anticipated, and then redoing everything due to some Wayland related findings)
  • Pi meetings

  • Learning about and making changes to Grafana dashboards - both for daily image metrics and autopkgtest-cloud.
  • Released and tested new charms in autopkgtest-cloud - first since May. Tested in staging and prod and made some amendments based on reported errors from users.
  • Fixing and working on the new usage of the autopkgtest-requestors team implementation in autopkgtest-web.
  • Polished an MP for utah which fixes an issue we’ve been having in venonat - desktop vm’s weren’t getting destroyed and undefined properly, leaving the vm in a shut off state with it’s storage staying on the disk and not getting deleted
  • Added a new suite of HTTP exceptions for autopkgtest-web in an effort to have more uniform responses to the user.
  • Wrote some documentation for contributing openqa tests and running locally
  • Added a timeout argument for a setup script in autopkgtest which can optionally reduce the time waiting for a setup script to run
  • Added functionality in autopkgtest-cloud which maps allowed releases and architectures e.g. trusty is in ESM so we only want to run tests on amd64 for it.
