diffoscope development

Development continued in git, including the following contributions:

• Chris Lamb:
  • Add support for “binwalking” to find (eg.) concatenated CPIO archives. (Closes: #820631)
  • Loosen matching of file(1)’s output to ensure we correctly also match TTF files under file 5.32.
  • Check we identify all CPIO fixtures in tests
  • Make failing a some flake8 tests cause the testsuite to fail. (Currently just “undefined name”)
  • Countless style fixups, eg. remove unused imports, removing blank lines from end of flies, etc.
  • Compare None using identity, not equality.
  • diffoscope.diff: Correct reference to self.buf.
  • comparators.utils.file: Correct reference to path_apparent_size.
• Juliana Rodrigues:
  • Sip html_visuals test if ‘sng’ binary is not available
• Mattia Rizzolo:
  • Numerous PEP8 fixes (eg. E122, E302, E713, etc.)

Mattia Rizzolo also uploaded the version 86 released last week to stretch-backports.

reprotest development

• Santiago Torres:
  • Correct string formatting in get_all_servers
• Ximin Luo:
  • Heavy refactoring towards supporting running more than 2 builds
  • Rename append_command to append_to_build_command

tests.reproducible-builds.org

• h01ger:
  • Don’t update the stretch package sets anymore
  • Update URL for Tails packages list
  • Disabled the OpenWrt at the request of lynxis as they were broken; if no-one shows up to fix them, we’ll probably remove them in the future, as all current development happens within LEDE.
  • Renewed the Let’s Encrypt SSL certificates.
• Mattia Rizzolo:
  • Avoid stale temporary files from reproducible_build.sh
  • Avoid removing the temporary directory twice
  • Fix IRC notifications when somebody asks for artifacts
  • Simplify ‘if’ conditions

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.
