Bug#990844: libtheora: reproducible builds: Embedded timestamps in PDF file

[Vagrant Cascadian]

Source: libtheora
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The build timestamp is embedded in /usr/share/doc/libtheora-dev/Theora.pdf.gz:

  https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/libtheora.html

  June·15,·2021
  vs.
  July·19,·2022

The attached patch fixes this by setting FORCE_SOURCE_DATE=1 in
debian/rules, which texlive needs in order to respect SOURCE_DATE_EPOCH,
which is set during debian package builds to the timestamp in the latest
debian/changelog entry.

  https://reproducible-builds.org/docs/source-date-epoch/


With this patch and the recently submitted patch removing
examples/Makefile, libtheora should build reproducibly on
tests.reproducible-builds.org


Thanks for maintaining libtheora!


live well,
