# Test matrix for the in-house LFOps plugins.
#
# LFOps plugins fall into two tiers with different runtime environments:
#
#   * Controller plugins (filter, lookup) run on the Ansible controller.
#     The controller requires Python >= 3.10 (ansible-core 2.16/2.17) or
#     >= 3.11 (2.18). These are covered by the `py3XX-ansibleXYZ` envs
#     below and run on standard CI runners via setup-python.
#
#   * Target plugins (modules, module_utils) run on the managed node and
#     must therefore support the oldest managed-node Python we still
#     maintain: Python 3.6 on RHEL 8. CI runners no longer ship Python
#     3.6, so that tier runs inside a RHEL 8 / UBI 8 container, see
#     `[testenv:py36-target]` below. The controller envs run these tests
#     as well, on their newer Python.
#
# ansible-core / controller-Python compatibility (see README.md):
#   2.16: py3.10-3.12   2.17: py3.10-3.12   2.18: py3.11-3.13
# `requires_ansible` in meta/runtime.yml is `>=2.16.0`, so 2.16 is the floor.

# Managed-node tier (modules / module_utils). Not in the default envlist. Run
# it inside a RHEL 8 / UBI 8 container, where the system Python is 3.6. tox 4
# no longer runs on Python 3.6, so run tox 3 there:
#
#   podman run --rm -v "$PWD":/src:Z -w /src registry.access.redhat.com/ubi8/ubi \
#     bash -c 'dnf -y install python3 python3-pip && pip3 install "tox<4" && tox -e py36-target'
#
# The tests import the module_utils of ansible-core 2.16, the last series that
# supports Python 3.6 on the managed node, just like the controller ships them
# in production. ansible-core itself needs Python 3.10, so only the package is
# put on PYTHONPATH, without its dependencies. The `Linuxfabrik: Unit Tests`
# workflow runs the same pytest command in that container, without tox, from
# the same hash-pinned requirements files.
