Upstreaming of reproducibility fixes
Weekly QA work
During our reproducibility testing, the following FTBFS bugs have been detected and reported by:
- Chris Lamb (4)
diffoscope 67 was uploaded to unstable by Chris Lamb. It included contributions from :
[ Chris Lamb ] * Optimisations: - Avoid multiple iterations over archive by unpacking once for an ~8X runtime optimisation. - Avoid unnecessary splitting and interpolating for a ~20X optimisation when writing --text output. - Avoid expensive diff regex parsing until we need it, speeding up diff parsing by 2X. - Alias expensive Config() in diff parsing lookup for a 10% optimisation. * Progress bar: - Show filenames, ELF sections, etc. in progress bar. - Emit JSON on the the status file descriptor output instead of a custom format. * Logging: - Use more-Pythonic logging functions and output based on __name__, etc. - Use Debian-style "I:", "D:" log level format modifier. - Only print milliseconds in output, not microseconds. - Print version in debug output so that saved debug outputs can standalone as bug reports. * Profiling: - Also report the total number of method calls, not just the total time. - Report on the total wall clock taken to execute diffoscope, including cleanup. * Tidying: - Rename "NonExisting" -> "Missing". - Entirely rework diffoscope.comparators module, splitting as many separate concerns into a different utility package, tidying imports, etc. - Split diffoscope.difference into diffoscope.diff, etc. - Update file references in debian/copyright post module reorganisation. - Many other cleanups, etc. * Misc: - Clarify comment regarding why we call python3(1) directly. Thanks to Jérémy Bobbio <firstname.lastname@example.org>. - Raise a clearer error if trying to use --html-dir on a file. - Fix --output-empty when files are identical and no outputs specified. [ Reiner Herrmann ] * Extend .apk recognition regex to also match zip archives (Closes: #849638) [ Mattia Rizzolo ] * Follow the rename of the Debian package "python-jsbeautifier" to "jsbeautifier". [ siamezzze ] * Fixed no newline being classified as order-like difference.
reprotest 0.5 was uploaded to unstable by Chris Lamb. It included contributions from:
[ Ximin Luo ] * Stop advertising variations that we're not actually varying. That is: domain_host, shell, user_group. * Fix auto-presets in the case of a file in the current directory. * Allow disabling build-path variations. (Closes: #833284) * Add a faketime variation, with NO_FAKE_STAT=1 to avoid messing with various buildsystems. This is on by default; if it causes your builds to mess up please do file a bug report. * Add a --store-dir option to save artifacts.
