Toolchains

  • rustc-1.85 update is complete! Currently awaiting review and sponsorship.
  • Introduction and quick conversation with upstream Rust development team regarding the 1.85 update. Will have future focus on building rapport with upstream.
  • Fixed issue with rustc-1.82 backport. Waiting for build to complete before requesting a binary archive copy from the security team.

Other

Questing

  • Finished specification of new A/B boot method (FO-233)
    • For full safety, requires the new mv --exchange flag (introduced in coreutils 9.5, though the kernel support has been around quite a while now)
    • … unfortunately rust coreutils doesn’t support this yet
    • … will rely on GNU coreutils to implement this for now
  • Created test implementation of A/B boot method
    • Testing migration, and various failure modes on a variety of boards
  • Sponsored new PiDNG package (part of the dependencies for picamera2) with some minor changes (LP: #2092277)

Posting updates for the last and the previous week as well.

Merges

  • plocate: Uploaded and migrated to release. (LP #2112057)
  • iputils: Uploaded and migrated to release. (LP #2112014)
  • pam: This is one is under review. MP here. It was an interesting one with pam moving to meson from autotools requiring quite a few updates to the patches. (LP #2112053)

SRU

  • remmina: There was discussion on the bug about adding additional tests to the test plan. The SRU to oracular was also missing. Updated the test plan and prepared an MP for the oracular SRU. (LP #2111952)

Toolchains

  • pylsp snap: This snap was originally a community snap. After approval from the author it has been transferred under ownership of the Toolchains squad. This will ensure it is maintained and kept up to date going forward giving users confidence that they can rely on this snap.

Misc

  • WI grading

My week was marred by a bout of sickness and a day off. I continued with my work on automated ISO testing.
