Bug#995401: canna: reproducible builds: Embedded timestamps in .dvi file

[Vagrant Cascadian]

Source: canna
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/canna/canna.dvi.gz:

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

  ... TeX·output·2022.
  vs.
  ... TeX·output·2021.

  ... 10.25:1509
  vs.
  ... 09.23:1050


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 applied, canna should build reproducibly on
tests.reproducible-builds.org


Thanks for maintaining canna!


live well,
