mimic: build/ops: install `python*-devel` for python*rpm-macros #30244

merged 1 commit into from Sep 8, 2019

smithfarm commented Sep 7, 2019

in 087ea81, we installed '*rpm-macros' for the macros, so we can have
access to the latest python packaging related macros for preparing the
build dependencies.

but we could run into, if
we already have an old version of python-devel installed. as the newer
version of python-rpm-macros conflicts with it.

it was a chicken-and-egg problem, as we don't know the exact name of
*rpm-macros packages. that's why we chose to install all of them. but
we have to upgrade the existing python-devel package to resolve the
conflict. but the since there is no python3-devel in RHEL7/CentOS7,
what they have is python36-devel. so we have to hardwire the
`%{python3_pkgversion}` to "36" even before we have access to this
macro, and upgrade the python36-devel package beforehand. but this
renders installing the rpm-macro package less useful -- we intend to
use the macro offered by the package to figure out "36".

as a workaround, we pretend that we know the "main" version of python3
in current RHEL/CentOS. and always install python36-devel for
python-rpm-macros. as the former requires the latter.

once all python3*-devel on all builders are upgraded, we will be safe
to install '*rpm-macros' again without installing python36-devel first.
by then, we could revert this change, or continue installing
python36-devel until the distro bumps up the "main" python version to 3.7
