Subject: lcov: reproducible builds: Embedded timestamps in manpages

Date: Sat, 10 Jul 2021 18:20:46 -0700

[Message part 1 (text/plain, inline)]

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

The build timestamp is embedded in various manpages:

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

  ./usr/share/man/man1/gendesc.1.gz

  .TH·gendesc·1·"LCOV·1.14"·2021\-06\-13·"User·Manuals"
  vs.
  .TH·gendesc·1·"LCOV·1.14"·2022\-07\-16·"User·Manuals"


The attached patch fixes this by changing updateversion.pl to use the
date specified by the SOURCE_DATE_EPOCH environment variable, which is
set by dpkg when building packages:

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


With this patch applied, lcov should be reproducible on
tests.reproducible-builds.org.


Thanks for maintaining lcov!


live well,
