Source: cdbs Version: 0.4.130 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi! The Debian reproducible builds team [1] recently proposed a new environment variable $SOURCE_DATE_EPOCH to be used by packages to produce reproducible timestamps (for example in documentation) [2]. This environment variable is currently being exported by debhelper from our experimental git repository which we have patched such that packages using dh (debhelper >= 9) in debian/rules become automatically reproducible. The patch to debhelper does not affect packages which use cdbs as their build system. Therefore I propose the attached patch which makes cdbs export $SOURCE_DATE_EPOCH. A version of cdbs with this patch is currently being used in the reproducible builds git repository and it has been successful at making a package become reproducible. This bug is in addition to this other bug from the reproducible builds team: https://bugs.debian.org/764478 Kind Regards, akira [1] https://wiki.debian.org/ReproducibleBuilds/About [2] https://wiki.debian.org/ReproducibleBuilds/TimestampsProposal
