Once again a glibc week:

  • Sent out an announcement on ubuntu-devel about the upcoming upload and its consequences
    • Followed a few days later by a erratum because apparently I suck at reading dates.
  • Conversation with various folks about the actual timing of the upload
  • Bug investigation: libdfp AFAICT it’s an issue related to some effort to remove malloc from the printf machinery. Investigation still ongoing.
  • 2.39 is out! And with it critical security fixes, yay!
    • Currently working out the last kinks before it is ready for upload tomorrow night.
  • Usual load of hiring-related tasks.

Release

  • autopkgtest db was accidentally lost on Monday, discovered by release team on Tuesday. In process of being regenerated from the swift data but this takes several days and in the meantime proposed-migration is basically not progressing because britney isn’t guaranteed to see the test results.
    • did some work to try to have britney fall back to direct swift access, which is what we used before implementing support for copying autopkgtest.db and accessing results via sqlite; but swift has migrated to a new location and new version since the last time we used that code and it doesn’t work out of the box.

Archive

  • debugging nvidia packages with wrong Phased-Update-Percentage in jammy-updates
  • discussion around rustc-1.74 (re)bootstrapping

SRU

  • out-of-cycle SRU review of livecd-rootfs SRU in jammy which has been lingering, in order to un-break Ubuntu Server daily image builds in run-up to 24.04.4.
