What happened in the reproducible builds effort between February 28th and March 5th:

Toolchain fixes

• Antonio Terceiro uploaded gem2deb/0.27 that forces generated gemspecs to use the date from debian/changelog.
• Antonio Terceiro uploaded gem2deb/0.28 that forces generated gemspecs to have their contains file lists sorted.
• Robert Luberda uploaded ispell/3.4.00-5 which make builds of hashes reproducible.
• C dric Boutillier uploaded ruby-ronn/0.7.3-4 which will make the output locale agnostic. Original patch by Chris Lamb.
• Markus Koschany uploaded spring/101.0+dfsg-1. Fixed by Alexandre Detiste.

Ximin Luo resubmitted the patch adding the --clamp-mtime option to Tar on Savannah's bug tracker. Lunar rebased our experimental dpkg on top of the current master branch. Changes in the test infrastructure are required before uploading a new version to our experimental repository. Reiner Herrmann rebased our custom texlive-bin against the latest uploaded version.

Patches submitted which have not made their way to the archive yet:

• #816232 on eficas by Reiner Herrmann: use printf instead of echo which is shell-independent.

Florent Daigniere and bancfc reported that linux-grsec was currently built with GRKERNSEC_RANDSTRUCT which will prevent reproducible builds with the current packaging.

tests.reproducible-builds.org pbuilder has been updated to the last version to be able to support Build-Depends-Arch and Build-Conflicts-Arch. (Mattia Rizzolo, h01ger) New package sets have been added for Subgraph OS, which is based on Debian Stretch: packages and build dependencies. (h01ger) Two new armhf build nodes have been added (thanks Vagrant Cascadian) and integrated in our Jenkins setup with 8 new armhf builder jobs. (h01ger)

strip-nondeterminism development strip-nondeterminism version 0.016-1 was released on Sunday 28th. It will now normalize the POT-Creation-Date field in GNU Gettext .mo files. (Reiner Herrmann) Several improvements to the packages metadata have also been made. (h01ger, Ben Finney)

Package reviews 185 reviews have been removed, 91 added and 33 updated in the previous week. New issue: fileorder_in_gemspec_files_list. 43 FTBFS bugs were reported by Chris Lamb, Martin Michlmayr, and gregor herrmann.

Misc. After merging the patch from Dhiru Kholia adding support for SOURCE_DATE_EPOCH in rpm, Florian Festi opened a discussion on the rpm-ecosystem mailing list about reproducible builds. On March 4th, Lunar gave an overview of the general reproducible builds effort at the Internet Freedom Festival in Valencia.

What happened in the reproducible builds effort this week: Toolchain fixes

• Stefano Rivera uploaded python-cffi/1.3.0-1 which makes the generated code order deterministic for anonymous unions and anonymous structs. Reported by Tristan Seligmann, and fixed uptream.

Mattia Rizzolo created a bug report to continue the discussion on storing cryptographic checksums of the installed .deb in dpkg database. This follows the discussion that happened in June and is a pre-requisite to add checksums to .buildinfo files. Niko Tyni identified why the Vala compiler would generate code in varying order. A better patch than his initial attempt still needs to be written. Packages fixed The following 15 packages became reproducible due to changes in their build dependencies: alt-ergo, approx, bin-prot, caml2html, coinst, dokujclient, libapreq2, mwparserfromhell, ocsigenserver, python-cryptography, python-watchdog, slurm-llnl, tyxml, unison2.40.102, yojson. The following packages became reproducible after getting fixed:

• 389-ds-base/1.3.3.13-1 uploaded by Timo Aaltonen, original patch by Chris Lamb.
• apache2/2.4.17-1 by Stefan Fritsch.

Some uploads fixed some reproducibility issues but not all of them:

• foxeye/0.10.2-1 by Andriy Grytsenko.
• jaxe/3.5-6 by Samuel Thibault.
• ncurses/6.0+20151017-1 by Sven Joachim, original patch by Esa Peuha.

reproducible.debian.net pbuilder has been updated to version 0.219~bpo8+1 on all eight build nodes. (Mattia Rizzolo, h01ger) Packages that FTBFS but for which no open bugs have been recorded are now tested again after 3 days. Likewise for depwait packages. (h01ger) Out of disk situations will not cause IRC notifications anymore. (h01ger) Documentation update Lunar continued to work on writing documentation for the future reproducible-builds.org website. Package reviews 44 reviews have been removed, 81 added and 48 updated this week. Chris West and Chris Lamb identified 70 fail to build from source issues. Misc. h01ger presented the project in Mexico City at the 3er Congreso de Seguridad de la Informaci n where it became clear that we lack academic papers related to reproducible builds. Bryan has been doing hard work to improve reproducibility for OpenWrt. He wrote a report linking to the patches and test results he published.
