Description

In preparation for Lyrical.

Is this user-facing behavior change?

Did you use Generative AI?

This should really be done in the same commit as Resolute, right?

[christophebedard]

I don't really know. We kind of need to bump to RHEL 10 to merge #868. Bumping to Resolute at the same time makes sense, but it feels like such the wrong time to do it, when we're trying to get other things in.

It looks like python3-pytest-asyncio is available for RHEL 9 via EPEL. Am I missing something? Why does moving to RHEL 10 block that PR?

[christophebedard]

I believe it requires Python >=3.12 (for some language features?). RHEL 9 has 3.9.

ros2/rclpy#1620 requires Python >= 3.12? I'm confused.

[christophebedard]

it is using asyncio task groups, which were added in 3.11: https://docs.python.org/3/library/asyncio-task.html#task-groups. And apparently it's also using a Python 3.12 feature.

However, we are currently discussing having a check to disable the feature (or just the tests) if the Python version is too old: #Client Libraries Working Group > AsyncNode @ 💬.

OK, as per #Client Libraries Working Group > AsyncNode @ 💬, Nadav is going to try skipping the tests so that we can stay on RHEL 9 for now. Closing this!
