Bug#1120875: python-graphene: please make the build reproducible

[Chris Lamb]

Source: python-graphene
Version: 3.4.3-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

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

This is because it ships a different binary package depending on
whether the testsuite is run or not.

Specifically, if the testsuite is run, a number of directories under
the examples/ directory have their modification times bumped if the
tests are run. (I suspect this is due to the creation of .pyc files
or __pycache__ dirs, but I haven't confirmed that). This means that
the binary package ends up with different directory metadata for
these dirs.

A patch attached is that will set these modification times to the
value of SOURCE_DATE_EPOCH, regardless of whether the tests are run.
