What happened in the reproducible builds effort between April 3rd and April 9th 2016: Media coverage Emily Ratliff wrote an article for SecurityWeek called Establishing Correspondence Between an Application and its Source Code - How Combining Two Completely Separate Open Source Projects Can Make Us All More Secure. Tails have started work on a design for freezable APT repositories to make it easier and practical to perform reproductions of an entire distribution at a given point in time, which will be needed to create reproducible installation- or live-media. Toolchain fixes Alexis Bienven e submitted patches adding support for SOURCE_DATE_EPOCH in several tools: transfig, imagemagick, rdtool, and asciidoctor. boyska submitted one for python-reportlab. Packages fixed The following packages have become reproducible due to changes in their build dependencies: atinject-jsr330 brailleutils cglib3 gnugo libcobra-java libgnumail-java libjchart2d-java libjcommon-java libjfreechart-java libjide-oss-java liblaf-widget-java liblastfm-java liboptions-java octave-control octave-mpi octave-nan octave-parallel octave-stk octave-struct octave-tsa oar The following packages became reproducible after getting fixed:

Other upstream fixes Alexander Batischev made a commit to make newsbeuter reproducible. tests.reproducible-builds.org

• An architecture agnostic summary has been added to the reproducible-tracker.json by Valerie Young to make it easy to parse whether a package is unreproducible anywhere.
• To find more reproducibility issues a new variation was added to the i386 builders, so that one build is done using a 32 bit kernel (686-PAE) and the other build is using a 64 bit kernel (amd64). (h01ger)
  • Niko Tyni was the first to notice a bug due to this: #821182 perl: embeds kernel architecture information
• The 2nd builds are now done in fr_CH on amd64, de_CH on i386 and it_CH on armhf. (h01ger)
• The variation table has been updated to reflect the recent changes and various small bugs have been fixed. (h01ger)

Package reviews 93 reviews have been removed, 66 added and 21 updated in the previous week. 12 new FTBFS bugs have been reported by Chris Lamb and Niko Tyni. Misc. This week's edition was written by Lunar, Holger Levsen, Reiner Herrmann, Mattia Rizzolo and Ximin Luo. With the departure of Lunar as a full-time contributor, Reproducible Builds Weekly News (this thing you're reading) has moved from his personal Debian blog on Debian People to the Reproducible Builds team web site on Debian Alioth. You may want to update your RSS or Atom feeds. Very many thanks to Lunar for writing and publishing this weekly news for so long, well & continously!

What happened in the reproducible builds effort between December 27th and January 2nd: Infrastructure dak now silently accepts and discards .buildinfo files (commit 1, 2), thanks to Niels Thykier and Ansgar Burchardt. This was later confirmed as working by Mattia Rizzolo.

• fltk1.3/1.3.3-5 by Aaron M. Ucko, currently FTBFS.

reproducible.debian.net The testing distribution (the upcoming stretch) is now tested on armhf. (h01ger) Four new armhf build nodes provided by Vagrant Cascandian were integrated in the infrastructer. This allowed for 9 new armhf builder jobs. (h01ger) The RPM-based build system, koji, is now in unstable and testing. (Marek Marczykowski-G recki, Ximin Luo). Package reviews 131 reviews have been removed, 71 added and 53 updated in the previous week. 58 new FTBFS reports were made by Chris Lamb and Chris West. New issues identified this week: nondeterminstic_ordering_in_gsettings_glib_enums_xml, nondeterminstic_output_in_warnings_generated_by_breathe, qt_translate_noop_nondeterminstic_ordering. Misc. Steven Chamberlain explained in length why reproducible cross-building across architectures mattered, and posted results of his tests comparing a stage1 debootstrapped chroot of linux-i386 once done from official Debian packages, the others cross-built from kfreebsd-amd64.
