[Vagrant Cascadian]

Source: lcov
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps timezone

The build timestamp is embedded in various /usr/bin/* files is timezone
dependent:

  lcov_1.16-1_all.deb

  -rwxr-xr-x···0·root·········(0)·root·········(0)·····4568·2022-06-06·08:19:45.000000·./usr/bin/gendesc
  vs.
  -rwxr-xr-x···0·root·········(0)·root·········(0)·····4568·2022-06-05·18:19:45.000000·./usr/bin/gendesc


The attached patch fixes this by removing a call to touch from the
updateversion.pl script.


According to my local tests, with this patch applied lcov should build
reproducibly on tests.reproducible-builds.org!


Thanks for maintaining lcov!


live well,
