Package: mkdocs
Version: 0.15.3-3
Severity: wishlist
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps toolchain
Control: affects -1 unburden-home-dir djangorestframework


mkdocs integrates build time stamps into the documentation it is
generating. This makes at least unburden-home-dir no more reproducibly
building because it now uses mkdocs to generate HTML documentation at
build time.

See https://tests.reproducible-builds.org/rb-pkg/unstable/amd64/unburden-home-dir.html and

Other cases of this issue are the source package djangorestframework (see
https://tests.reproducible-builds.org/rb-pkg/testing/i386/djangorestframework.html and
and of course the source package python-mkdocs itself, see
https://tests.reproducible-builds.org/rb-pkg/unstable/amd64/python-mkdocs.html and

At https://reproducible-builds.org/specs/source-date-epoch/ you can find
a bound to be widely adopted specification for how to solve such kind of
issues generally: If the environment variable SOURCE_DATE_EPOCH exists
use the Unix time stamp (seconds since 1st of January 1970, 00:00:00
UTC) it contains to preseed all build time stamps with that time stamp
instead of the current time.

See https://wiki.debian.org/ReproducibleBuilds/TimestampsProposal#Examples
for some examples on how to implement support for SOURCE_DATE_EPOCH,
including an example for Python.
