Reproducible Builds: Weekly report #51

Published: Apr 20, 2016.

What happened in the reproducible builds effort between April 10th and April 16th 2016:

Toolchain fixes

  • Roland Rosenfeld uploaded transfig/1:3.2.5.e-6 which honors SOURCE_DATE_EPOCH. Original patch by Alexis Bienvenüe.
  • Bill Allombert uploaded gap/4r8p3-2 which makes honor SOURCE_DATE_EPOCH. Original patch by Jerome Benoit, duplicate patch by Dhole.
  • Emmanuel Bourg uploaded ant/1.9.7-1 which makes the Javadoc task use UTF-8 as the default encoding if none was specified and SOURCE_DATE_EPOCH is set.

Antoine Beaupré suggested that gitpkg stops recording timestamps when creating upstream archives. Antoine Beaupré also pointed out that git-buildpackage diverges from the default gzip settings which is a problem for reproducibly recreating released tarballs which were made using the defaults.

Alexis Bienvenüe submitted a patch extending sphinx SOURCE_DATE_EPOCH support to copyright year.

The following packages have become reproducible due to changes in their build dependencies: atinject-jsr330, avis, brailleutils, charactermanaj, classycle, commons-io, commons-javaflow, commons-jci, gap-radiroot, jebl2, jetty, libcommons-el-java, libcommons-jxpath-java, libjackson-json-java, libjogl2-java, libmicroba-java, libproxool-java, libregexp-java, mobile-atlas-creator, octave-econometrics, octave-linear-algebra, octave-odepkg, octave-optiminterp, rapidsvn, remotetea, ruby-rinku, tachyon, xhtmlrenderer.
