1568145 - langpack version varies between builds

Status: RESOLVED DUPLICATE of bug 1565504

(Firefox Build System :: General, defect)

Description

[Bernhard M. Wiedemann]

Attachment: MozillaFirefox-reproducible-langpack.patch

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0

Steps to reproduce:

Build the openSUSE:Factory/MozillaFirefox package twice

Actual results:

All langpacks had one of their version fields differ as seen in
https://rb.zq1.de/compare.factory-20190713/MozillaFirefox-compare.out

Expected results:

It should be possible to get bit-identical results from multiple builds, even without mercurial metadata.
See https://reproducible-builds.org/ for why.

Please review/test/merge the attached patch
or come up with a better patch (e.g. use the MOZ_BUILD_DATE environment variable)
