The test failures are unrelated. Thanks for the PR!

So I just noticed that I didn't properly test this: the first CI run is testing branch mergify/bp/kilted/pr-36 across all repos, which ends up testing ros2/ament_cmake_ros#36 and not this PR. This is because I'm using the ros-ci-for-pr script and re-used a previous command without removing the --branch option. It commented on this PR but didn't test this PR. I only noticed now when triggering CI for another PR.

I think this PR would be fine, but it uses logging.getLevelNamesMapping(), which is only available in Python 3.11. That is greater than the minimum Python language requirement for Rolling/Kilted: https://www.ros.org/reps/rep-2000.html#kilted-kaiju-may-2025-november-2026. Therefore, based on this, I'll revert this PR right away.

Reverted in #865. We'll see if CI passes above, but just based on the minimum Python requirement, we'll have to find an alternative to logging.getLevelNamesMapping().

@InvincibleRMC would you be willing to open another PR that doesn't use logging.getLevelNamesMapping()?

Yeah definitely.

So it does fail on RHEL: https://ci.ros2.org/job/ci_linux-rhel/2748/testReport/junit/launch.test.launch.actions/test_log/test_log_execute/. Windows will probably fail too, knowing that it has an older Python version, but I'll just cancel it.
