Java & openjdk

TCK

  • Analysis of networking tests failing only on Ubuntu Desktop (the 127.0.1.1 entry in /etc/hosts).
    Documented my understanding in the tck-17 & tck-21 repositories’ READMEs.
  • Ran tck-17 & tck-21 on noble-arm64 (RPi5 board), all well

openjdk-8 security release

  • Spent time on triage of new JTREG failures on mantic, jammy, focal, bionic (a large armhf list is still pending)

FIPS crypto provider prototype

  • prototyped a Java wrapper and tests for Message Authentication Codes

Very short week (2 days).

Distro

  • MIR libtraceevent (see LP #2051916)
    • Patch to fix TODOs waiting for sponsoring.
  • MIR libtracefs (see LP #2051925)
    • Trying to diagnose why tests are failing (they never ran before in CI so maybe some never passed)

ubuntu-image

  • PR #192 - Enable not generating artifacts
    • WIP. I potentially uncovered another unrelated issue, so it might need more investigation than anticipated.

imagecraft

  • Refine imagecraft.yaml spec with @sil2100

Misc.

  • catching up after 3 days OOO
  • setting up a RPi5 to have a local arm64 builder
  • 360 reviews

Distro

  • Resumed work on the crypto-config specification with a strong goal of having it validated and published by the end of this cycle
  • Some time spent on openssl 3.0.13 which is waiting for the t64 transition to conclude first
  • More review of FIPS patches that we would like to integrate into Noble and SRU to previous releases (no behavior change when not running with the kernel in FIPS mode, don’t worry)

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

  • Tests on Ubuntu, mostly done but I need to fine-tune the package list; haven’t looked at statistics yet

Misc

  • A day off at last
  • Experimented with ways to reduce memory usage of the excuses page (50% lower for the global one, smaller improvements for the by_team one) while also improving the UI and UX (results shown in tables!)
  • Created next week’s status post: Foundations Team Updates - Thursday 2024/03/14
  • Toyed with data retrieval and extraction from our status posts along with AI and LLMs but finally used word clouds to come up with some “highlights” for the team members during this cycle:

General

  • 64-bit time_t
  • the NMUs to unstable landed, and have mostly made their way into noble-proposed via autosync. A few libraries will still need merges, but the core set (that make the most mess for rebootstrapping) appear to have now landed.
  • Worked on bootstrapping against the new libraries: perl and python are bootstrapped, apt is bootstrapped
  • added a hack to apt in the form of an artificial Conflicts: libnettle8 to hint the resolver in the buildd chroots to remove libraries and let apt upgrade. Seems to be working now in the bootstrap ppa.
  • working on bootstrapping rustc against an out-of-archive build to get around the self-build-dep on cargo (via dh-cargo). This blocks a lot of things via python-cryptography. Maybe will work now that apt is upgradeable.
  • Had done part of the bootstrap of glib2.0 but then got sucked into other parts of the graph and unfortunately left it broken on !armhf for a long time in noble-proposed, breaking builds of other things. Jeremy BĂ­cha took care of cleaning this up, but glib2.0 bootstrap is still a big project.
  • Doing a lot of binNMUs in Debian on armel and armhf, as they have the same bootstrap requirements there

Release

  • Did an early NBS removal of libefivars1 and libefiboot1 from noble because these were breaking image builds because something wanted to pull in the real package during an image build instead of the virtual package now provided by libefivars1t64, causing a conflict.

I’ve been off for the last 2 Thursdays, so I missed the last 2 Ubuntu meetings. I’m consolidating everything in this post:

dotnet

  • Worked on building .NET 8 on s390x
  • Tested and validated the s390x .NET build
    • Ran the Red Hat testsuite and worked on fixing some failing tests and skipping ones that don’t apply
    • Ran our own autopkgtests with positive results
  • Worked on the new .NET snaps and the .NET installer tool:
    • Investigated installability of .NET workloads in the new snap format, which now works
    • Implemented “update available” logic when listing available .NET versions
    • Implemented reverse-dependency lookup and removal when uninstalling a .NET component with the installer tool.

Go

  • Go 1.22.1 & 1.21.8 release.

  • Go 1.22 transition
    Look at some packages that need special attention when doing archive rebuild with golang-1.22.
