Weekly QA work

During our reproducibility testing, the following FTBFS bugs have been detected and reported by:

• Chris West (19)
• Chris Lamb (7)
• Rob Browning (1)

diffoscope development

• Chris Lamb:
  • Optimisations:
    • Avoid unnecessary string manipulation writing –text output (~20x speedup).
    • Avoid n iterations over archive files (~8x speedup).
    • Memoize calls to distutils.spawn.find_executable to avoid excessive stat(1) syscalls.
  • Progress bar:
    • Show current file / ELF section under analysis etc. in progress bar.
    • Move the --status-fd output to use JSON and to include the current filename.
  • Code tidying:
    • Split out the try.diffoscope.org client so that it can be released separately on PyPI.
    • Completely rework the diffoscope and diffoscope.comparators modules, grouping similar utilities into their own modules, etc.
  • Miscellaneous:
    • Ensure that running from Git will always use that checkout’s Python modules.
• Mattia Rizzolo:
  • Follow the rename of the debian package ‘python-jsbeautifier’ to ‘jsbeautifier’
• Reiner Herrmann:
  • apk: Extend recognition regex to also match zip archives
• siamezzze:
  • Fixed no newline being classified as order-like difference.

strip-nondeterminism development

• strip-nondeterminism 0.029-2 was uploaded to unstable by Mattia Rizzolo to include a fix by Chris Lamb to fix the autopkgtest tests.

try.diffoscope.org development

• Chris Lamb:
  • Show progress bar and position in queue, etc.
  • Promote command-line client with PyPI instructions.
  • Increase comparison time limit to 90 seconds.

tests.reproducible-builds.org

• Run half of the arm64 build nodes in the future. (h01ger)
