Reproducible Builds: Weekly report #135

Published: Nov 29, 2017.

Here’s what happened in the Reproducible Builds effort between Sunday November 19 and Saturday November 25 2017:

Upcoming events

Reproducible Builds will have an assembly at 34c3, the “Galactic Congress”. ;-) Currently we are discussing to informally meet there every day at 13:37 UTC.

Reproducible Arch Linux

Since November 23 2017, Arch Linux is again being continuously tested for reproducibility. However, this time a patched pacman is being used which can create reproducible packages. After 4 days of testing, 18% of all packages in the core, extra, multilib and community Arch repos has been tested, with these — very preliminary — results:

  • core: 77.1% reproducible, all 197 packages tested.
  • extra: 75.2% reproducible, 514 packages (of 2250 total) tested.
  • multilib: 82.6% reproducible, all 259 packages tested.
  • community: 76.5% reproducible, 487 packages (of 7739 total) tested.

Jelle van der Waa also wrote a blog post explaining more details detailing how this already had lead to more QA work in Arch.

So all in all, it looks like 77.2% of the tested Arch Linux packages are now reproducible! With an unreleased pacman version and without some variations we apply when testing Debian… still this is a very good start! Kudos to all involved.

    • Disabled ASLR and
    • Building with fixed PIDs.
    • Also the tar wrapper script got a bug fix.

reprotest development

reproducible-website development

  • anthraxx worked on reproducible Arch Linux (19 commits)
  • Holger Levsen did some work on reproducible Debian:
    • aa9ce22d6 - Update email subject of status change mails to use t.r-b.o/debian - thanks to lamby for #882186
  • Holger mostly worked on reproducible Arch Linux that week (56 commits).
  • Misc tests.r-b.o work by Holger:
    • 0d79ab54a - reproducible Fedora: be explicit that this is stalled atm
    • Holger also reviewed and deployed 25 commits from other people.
    • Finally, Holger moved IRC notifications for from #debian-reproducible to #reproducible-builds (and kept them on #debian-qa as well).
  • Johannes Löthberg worked on Arch Linux as well (2 commits)
  • kpcyrd also worked on Arch Linux (5 commits)

Finally there was discussion to how to generalise the database schema for supporting several projects, triggered by the recent work on reproducible Arch, but also previously discussed in the context of openSUSE, LEDE and FreeBSD.


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