diffoscope development

Version 87 was uploaded to unstable by Mattia Rizzolo. It included contributions from:

• Ximin Luo:
  • comparators/*:
    • Add a test for fallback_recognizes and improve the behaviour
    • Add a fallback_recognizes to work around file(1) #876316. (Closes: #875272)

    • Add a –force-details flag for debugging
  • presenters.html:
    • Restore the previous more-detailed comment
    • Don’t show pointer-cursor when jQuery is disabled
    • Prune all descendants properly (Closes: #875281)
  • difference.py:
    • Also copy self._comment properly, compare self._visuals in equals()
    • In fmap/map_lines, don’t forget about self._visuals
    • Use diff_split_lines everywhere
  • tests:
    • Add case for #875281
    • Make test_md5sums less brittle
    • Update test_deb for new string
  • readers: Convert bytes to str in the right place
  • config: Force-set a value if it must be < another and it was not set on purpose (Closes: #875451)
  • Bump minimum Python version to 3.5 as we use syntax introduced by PEP 448
• Chris Lamb:
  • Print a debugging message if we are reading diff from stdin.
  • Compare types with identity not equality.
  • diffoscope.presenters.html: Use logging.py’s lazy argument interpolation.
  • debian/control: Bump Standards-Version to 4.1.0.

  • debian/rules: Place “before” commands before “after” commands.

strip-nondeterminism development

• Chris Lamb:
  • Log which handler processed a file. (Closes: #876140)
  • Bump Standards-Version to 4.1.0.

reprotest development

Version 0.7 was uploaded to unstable by Ximin Luo:

• Ximin Luo:
  • Push use of UNIX return codes to the edges of the program
  • Add a –auto-build option to determine which variations cause unreproducibility
  • Allow umask and user_group to both vary at the same time
  • Generate build names in main instead of build, guard against dupes
  • Pull traceback-printing stuff out of the core code
  • More refactoring, make check() contain only logic that would be changed in an auto-detector
  • Split check() into a coroutine producer and consumer, prepares auto-detection

tests.reproducible-builds.org

Vagrant Cascadian and Holger Levsen:

• Re-add and armhf build node that had been disabled due to performance issues, but works linux 4.14-rc1 now! #876212

Holger Levsen:

• Use botch from stretch to fix the jenkins job which create the package sets. (botch is currently uninstallable in sid and from pre-stretch-release times we used a sid schroot to install and use botch.)

Misc.

This week’s edition was written by Bernhard M. Wiedemann, Chris Lamb, Vagrant Cascadian & reviewed by a bunch of Reproducible Builds folks on IRC & the mailing lists.
