autopkgtest-cloud

  • Investigating issues in production with various datacentres
  • Made an MP to hopefully fix the issue of missing tests
  • Made an MP to migrate our amqp-status-collector script (the thing that populates running.json) to be a oneshot service, rather than long running
  • Continuing work on migrating from mojo to terraform - pretty much done, just having an issue running tflint in LPCI
  • MP improving the admin experience of using our cleanup-ppa-containers script

proposed-migration

  • Daily runs of retry-autopkgtest-regressions, since there’s some infra issues atm
  • Britney MP to not attempt to remove NBS kernel packages needlessly

ubuntu-archive-tools
Modified my MP with my britney-log-parser script to handle both compressed and uncompressed log files.

Installer Testing

  • Continuing trying to iron out edge case failures in my suite of desktop installer tests
  • Liaising with desktop and kernel teams r.e. installer testing and TPM FDE testing

autopkgtest

  • Made an MP changing schroot tests to run on Ubuntu chroots when running on Ubuntu hosts, which also fixes the suite on armhf.

autopkgtest-cloud

  • Setup new grafana panels to display stats for total number of packages we run autopkgtest for, and the percent of these packages which have successful baselines.
  • Incidental to getting the stats to feed to grafana, reduced autopkgtest.ubuntu.com/statistics loading time drastically (over 99% by my count).

auto-upgrade-testing

  • Experimenting with templated cloud-init configs to create custom images for different upgrade paths.

Misc

  • Got access to the engineering bastion, all arches are now able to create and use VMs from the bastion.
  • Retried a few hundred test regressions due to infra flakiness.

gradle upgrade:

  • investigating ways to bring up Gradle up to date. Considering building using binary bootstraps as other options (iterative upgrade, covert build to Maven) will require extreme effort.

Rocks:

O3 testing:

  • reran benchmarks for Oracular. The results require additional profiling to understand regressions.
