[pkg-lua-devel] Bug#1121802: lua-penlight: please make the build reproducible

[Chris Lamb]

Source: lua-penlight
Version: 1.14.0-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
lua-penlight could not be built reproducibly.

This is because running the tests curiously bumps the mtime of the
testclone.lua file. A patch is attached that resets the mtime of
this file to a deterministic value (and does so regardless of whether
the tests are run or not).
