Reproducible Builds: Weekly report #173

Here’s what happened in the Reproducible Builds effort between Sunday August 12 and Saturday August 18 2018:

• Christoph Berg merged support for reproducible builds in the PostGIS spatial database extensions for the PostgreSQL database.

• Arnout Engelen et al., continued an interesting discussion on our mailing list which compares the approaches Debian and Arch with respect to .buildinfo files. intrigeri added a description of the closest thing Tails has to a .buildinfo file.

• Alexis Murzeau updated diffoscope (our in-depth “diff-on-steroids” utility which helps us diagnose reproducibility issues in packages) to fix matching for .deb archive members, closing Debian bug #903565. In addition, Joannis Valasakis filed an ITP (Intent To Package) bug in Debian for fsdiff, a tool to compare two filesystems which may be useful to incorporate.

• A patch to was merged to the LLVM compiler addressing an ordering issue in Objective-C binaries. It now sorts a hash that varied from Address space layout randomization (ASLR).

• A long-open bug in the Gconf configuration management system for GNOME was finally marked as WONTFIX.

• Two package reviews were added, three were updated and 11 were removed in this week, adding to our knowledge about identified issues in Debian. A new jekyll_site_time_timestamp toolchain issue was identified by Chris Lamb.

Packages reviewed and fixed, and bugs filed

• Chris Lamb:

  • jekyll: Use SOURCE_DATE_EPOCH as the value of site.time.

• Bernhard M. Wiedemann:

  • benchmark (fix FTBFS-j1)
  • ffado (CPU)
  • gtk (sort readdir(2), for balsa font cache)
  • ldc (drop CPU type, random-FTBFS)
  • liquid-dsp (CPU, FTBFS-SSE2)
  • nut (parallelism race, sort readdir(2))
  • purple-rocketchat (date)
  • rlwrap (parallelism race)
  • upsm (convert -strip .png)

• Nico Weber:

  • chromium (use date of last Git commit)

tests.reproducible-builds.org development

There were a number of updates to our Jenkins-based testing framework that powers tests.reproducible-builds.org, including:

• Chris Lamb:
  • Print zero (not an empty) string when division denomination is zero.
• Holger Levsen:
  • Be more verbose if some services are not running.
  • Don’t show “known-offline” nodes as problematic.
  • Drop experimental schroot setup jobs from health overview.

Misc.

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