diffoscope development

• Chris Lamb:
  • Document the ‘h’ variable in our raw_feeder
  • Split diffoscope.difference into feeders
  • Tidy diffoscope/difference.py
• Ximin Luo:
  • Add a PartialString class
  • More ydiff/linediff from diffoscope.{difference => diff} to group unified_diff related things together
  • difference: has_children -> has_visible_children, and take into account comments
  • Add various traverse_ methods to Difference
  • Move side-by-side and linediff algorithms to difference.py
  • Refactor html-dir presenter to be a class instance, avoiding global state
  • html-dir: show/hide diff comments, which can be very large

As you might have noticed, Debian stretch was released last week. Since then, Mattia and Holger renamed our testing suite to stretch and added a buster suite so that we keep our historic results for stretch visible and can continue our development work as usual. In this sense, happy hacking on buster; may it become the best Debian release ever and hopefully the first reproducible one!

• Vagrant Cascadian:
  • Proposed reducing the number of concurrent builds each armhf machine runs, to reduce out-of-memory errors, crashes and false positives with FTBFS on armhf, reducing the number of armhf build workers from 70 to 51.
• Valerie Young: Add highlighting in navigation for the new nodes health pages.
• Mattia Rizzolo:
  • Do not dump database ACL in the backups.
  • Deduplicate SSLCertificateFile directive into the common-directives-ssl macro
  • Apache: t.r-b.o: redirect /testing/ to /stretch/
  • db: s/testing/stretch/g
  • Start adding code to test buster…
• Holger Levsen:
  • Update README.infrastructure to explain who has root access where.
  • reproducible_nodes_info.sh: correctly recognize zero builds per day.
  • Add build nodes health overview page, then split it in three: health overview, daily munin graphs and weekly munin graphs.
  • reproducible_worker.sh: improve handling of systemctl timeouts.
  • reproducible_build_service: sleep less and thus restart failed workers sooner.

  • Replace ftp.(de

    uk

    us).debian.org with deb.debian.org everywhere.

  • Performance page: also show local problems with _build_service.sh (which are autofixed after a maximum of 133.7 minutes).
  • Rename _nodes_info job to _html_nodes_info.
  • Add new node health check jobs, split off from maintenance jobs, run every 15 minutes.
    • Add two new checks: 1. for correct future (2019 is incorrect atm, and we sometimes got that). 2.) for writeable /tmp (sometimes happens on borked armhf nodes).
  • Add jobs for testing buster.
  • s/testing/stretch/g in all the code.
  • Finish the code to deal with buster.
  • Teach jessie and Ubuntu 16.04 how to debootstrap buster.

Axel Beckert is currently in the process of setting up eight [LeMaker HiKey960 boards]((http://www.96boards.org/product/hikey960/). These boards were sponsored by Hewlett Packard Enterprise and will be hosted by the SOSETH students association at ETH Zurich. Thanks to everyone involved here and also thanks to Martin Michlmayr and Steve Geary who initiated getting these boards to us.

Misc.

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