Bug#990248: vlc: reproducible builds: builds different default.vlt file depending on umask

[Vagrant Cascadian]

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

The umask of the build user affects the generated default.vlt, setting
permissions on various files differently:

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

  ./usr/share/vlc/skins2/default.vlt

  drwxr-xr-x···0·root·········(0)·root·········(0)········0·2021-01-17·22:11:09.000000·default/
  vs.
  drwxrwxr-x···0·root·········(0)·root·········(0)········0·2021-01-17·22:11:09.000000·default/


The attached patch fixes this by passing a mode argument to tar.


This patch does not address all reproducibility issues in vlc
(e.g. build paths), though applying it reduces the diff for the
remaining issues.


Thanks for maintaining vlc!


live well,
  vagrant
