What happened in the Reproducible Builds effort between May 22nd and May 28th 2016:

Media coverage

Documentation update

  • The wiki page TimestampsProposal has been extended to cover more usage examples and to list more softwares supporting SOURCE_DATE_EPOCH. (Axel Beckert, Dhole and Ximin Luo)
  • h01ger started a reference card for tools and information about reproducible builds but hasn't progressed much yet. Help with it is much welcome, this is also a good opportunity to learn about this project ;-) The idea is simply to have one coherent place with pointers to all the stuff we have and provide, without repeating nor replacing other documentation.

Toolchain fixes

  • Alexis Bienvenüe submitted a patch (#824050) against emacs24 for SOURCE_DATE_EPOCH support in autoloads files, but upstream already disabled timestamps by default some time before.
  • proj/4.9.2-3 uploaded by Bas Couwenberg (original patch by Alexis Bienvenü) properly initializes memory with zero to prevent the nad2bin tool from leaking random memory content into output artefacts.
  • Reiner Herrmann submitted a patch (#825569, upstream) against Ruby to sort object files in generated Makefiles, which are used to compile C sources that are part of Ruby projects.

Packages fixed

The following 18 packages have become reproducible due to changes in their build dependencies: canl-c configshell dbus-java dune-common frobby frown installation-guide jexcelapi libjsyntaxpane-java malaga octave-ocs paje.app pd-boids pfstools r-cran-rniftilib scscp-imcce snort vim-addon-manager

The following packages have become reproducible after being fixed:

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

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

Package reviews

123 reviews have been added, 57 have been updated and 135 have been removed in this week.

21 FTBFS bugs have been reported by Chris Lamb and Santiago Vila.

strip-nondeterminism development

  • strip-nondeterminsim development: treat *.htb as Zip files (by Sascha Steinbiss).
  • strip-nondeterminism 0.017-1 uploaded by h01ger.


  • The kde pkg set was extended, though the change ain't visible yet, as there are currently non-installable packages in it (and so the set can't be computed). (h01ger)


  • Mattia improved misc.git/reports (=the tools to help writing the weekly statistics for this blog) some more.

This week's edition was written by Reiner Herrmann and Holger Levsen and reviewed by a bunch of Reproducible builds folks on IRC.
