[Reproducible-builds] Bug#825881: pyx: please make the build reproducible (timestamps, randomness)

[Alexis Bienvenüe]

Source: pyx
Version: 0.12.1-4
Severity: wishlist
Tags: patch upstream
User: reproducible-builds at lists.alioth.debian.org

Dear Maintainer,

While working on the `€œreproducible builds'€ effort [1], we have noticed
that 'pyx' could not be built reproducibly.

Please find attached proposed solutions for the following issues:
* timestamps in the produced ps/pdf files can be made reproducible using
the SOURCE_DATE_EPOCH environment variable [2] (when set), that
corresponds to the last debian/changelog entry date when building a
debian package. See reproducible-timestamps.patch
* image names include memory addresses. They can eg. be replaced by some
hash of the image itself, see reproducible-image-name.patch

Once applied, pyx can be built reproducibly in our current
experimental framework.

Regards,
Alexis Bienvenüe.
