Weekly QA work

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

• Chris Lamb (5)
• Lucas Nussbaum (8)
• Santiago Vila (1)

diffoscope development

• diffoscope 63 was uploaded to unstable by Ximin Luo:

  • Greatly improve speed for large archives by fixing O(n^2) complexity for archive member lookup.
  • add +/- buttons to toggle visibility of parts of the diff
  • Output coloured diff using colordiff(1) via –text-color={never,auto,always}

Is is available now in Debian, Archlinux and on PyPI.

strip-nondeterminism development

• At the Reproducible Builds Boston hackathon Anders Kaseorg filed #846895 treat .par files as Zip archives, including a patch which was merged into master.

reprotest development

• reprotest 0.4 was uploaded to unstable by Ximin Luo:

  • disorderfs variation: don’t query the testbed, put that in the script instead
  • Add a build_path_same variation to run builds from the same path
  • Fix auto-presets in the case of a file in the current directory
  • Fix d/control so reprotesting reprotest in sbuild works (6 reproductions)
  • Add util-linux to Recommends since we use it to vary some things

tests.reproducible-builds.org

• Holger made a couple of changes:

  • Group all “done” and all “open” usertagged bugs together in the bugs graphs and move the “done bugs” from the bottom of these gaps.
  • Update list of packages installed on .debian.org machines.
  • Made the maintenance jobs run every 2h instead of 3h.
  • Various bug fixes and minor improvements.

• After thorough review by Mattia, some patches by Valerie were merged in preparation of the switch from sqlite to Postgresql, most notably a conversion to the sqlalchemy expression language.

• Holger gave a talk at Profitbricks about how Debian is using 168 cores, 503 GB RAM and 5 TB storage to make jenkins.debian.net and tests.reproducible-builds.org run. Many thanks to Profitbricks for supporting jenkins.debian.net since August 2012!

• Holger created a Jenkins job to build reprotest from git master branch.

• Finally, the Jenkins Naginator plugin was installed to retry git cloning in case of Alioth/network failures, this will benefit all jobs using Git on jenkins.debian.net.

Misc.

This week’s edition was written by Chris Lamb, Valerie Young, Vagrant Cascadian, Holger Levsen and reviewed by a bunch of Reproducible Builds folks on IRC.
