Subject: carbon-c-relay: make the build reproducible

Date: Mon, 5 Nov 2018 22:51:22 -0500

Source: carbon-c-relay
Version: 3.2-1
Severity: wishlist
Tags: patch
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

Hi there,

While working on the reproducible builds project
(https://wiki.debian.org/ReproducibleBuilds), we noticed that
carbon-c-relay could not be built reproducibly.

The attached patch changes the build system to first attempt to use
the SOURCE_DATE_EPOCH envvar
(https://reproducible-builds.org/specs/source-date-epoch/) to
determine build date, then falls back to the git commit date, then the
current date.

Best,
-Nick Gregory

Good idea. Fancy forwarding this upstream? Looks like they have a Github repo here:

  https://github.com/grobian/carbon-c-relay

… which should make it straightforward enough. You can the use the
BTS "forwarded" command to link them together:

  https://www.debian.org/Bugs/server-control#forwarded


Best wishes,
