Armhf 64-bit time_t analysis

  • lots of work on the script
  • dumps now contain apt logs along with abi-compliance-checker input and output files
  • all files created now have unique names/paths
  • added logic to skip already dumped or failed or skipped or known-uninstallable packages when doing the ABI dumps
  • created scripts to do the ABI diffs, possibly on a machine that wasn’t used for the dumps, and possibly parallelized
  • fixed the analysis for a few dozen packages: r-(cran|bioc)-* (missing dep and -I flag) and skip gnustep/objc packages
  • massaged the script until it managed to attempt dumping the ABI of every 5500 package from our list
  • reverted to assuming there is always enough memory to run every dump in parallel and set up zram locally for that to be true on a pi5
  • TODO: commit and upload that; start the dump step again

autopkgtest

  • Investigation into issues with our armhf test runners discovered that multiple arm64 instances, with armhf containers, were OOM’ing.

  • Reviewed @skia’s graphviz MP for the autopkgtest environment.
  • Submitted an RT regarding latency between PS5 and bos02.scalingstack which is affecting the armhf test runners.

  • Submitted a bug regarding errors (context deadline) seen in log files for the armhf test runner services.
