Here's what happened in the Reproducible Builds effort between Sunday October 1 and Saturday October 7 2017:

Media coverage

Documentation updates

Packages reviewed and fixed, and bugs filed

Reviews of unreproducible packages

32 package reviews have been added, 46 have been updated and 62 have been removed in this week, adding to our knowledge about identified issues.

Weekly QA work

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

  • Adrian Bunk (27)

diffoscope development

strip-nondeterminism development

Rob Browning noticed that strip-nondeterminism was causing serious performance regressions in the Clojure programming language within Debian. After some discussion, Chris Lamb also posted a query to debian-devel in case there were any other programming languages that might be suffering from the same problem.

reprotest development

Versions 0.7.1 and 0.7.2 were uploaded to unstable by Ximin Luo:

  • New features:
    • Add a --auto-build option to try to determine which specific variations cause unreproducibility.
    • Add a --source-pattern option to restrict copying of source_root, and set this automatically in our presets.
  • Usability improvements:
    • Improve error messages in some common scenarios.
      • Fiving a source_root or build_command that doesn't exist
      • Using reprotest with default settings after not installing Recommends
    • Output hashes after a successful --auto-build.
    • Print a warning message if we reproduced successfully but didn't vary everything.
  • Fix varying both umask and user_group at the same time.
  • Have dpkg-source extract to different build dir if varying the build-path.
  • Pass --exclude-directory-metadata to diffoscope(1) by default as this is the majority use-case.
  • Various bug fixes to get the basic dsc+schroot example working.

It included contributions already covered by posts of the previous weeks, as well as new ones from:

tests.reproducible-builds.org

Misc.

This week's edition was written by Bernhard M. Wiedemann, Chris Lamb, Holger Levsen, Mattia Rizzolo & reviewed by a bunch of Reproducible Builds folks on IRC & the mailing lists.
