Pants: add `python_distribution` BUILD metadata for st2* components #5909

cognifloyd · 2023-02-20T20:07:24Z

Background

This is another part of introducing pants, as discussed in various TSC meetings.

Related PRs can be found in:

pantsbuild milestone (which includes PRs since Initialize pantsbuild #5713)
pantsbuild label (which also includes preparatory PRs that came before adding pantsbuild)

Overview of this PR

This PR adds the st2_component_python_distribution() macro to the BUILD metadata for all of our components (st2common, st2client, st2auth, etc).

Thanks to the macro, we only have to define 3 (or 4) parameters for each runner: component_name, scripts, and entry_points. I copied the scripts and entry_points from the setup.py file, which will become obsolete once pants can generate the setup.py file for us.

Under entry_points, I have "tagged" the st2auth.sso.backends, the st2common.metrics.driver and the st2common.rbac.backend categories as stevedore_namespaces. Once we switch to 2.16 and enable the pants.backend.experimental.python.framework.stevedore plugin, the stevedore plugin will, for tests, use this "tag" to look up which wheels implement a plugin in that stevedore namespace.

To facilitate comparison, I will add a comment to each of the files that shows the current setup.py entry_points and scripts.

Next steps

Follow-up PRs will adjust the dependencies on the python_distributions to ensure all files get included.

Plus I noticed that st2-packaging needs runners.sh, so I included that as well.

A few of the scripts were missing in setup.py, so I included them here. Also, a couple of them were missing the execute bit, so I added that as well.,

Why are st2common/bin/st2-purge-task-executions and st2common/bin/st2-purge-workflows now empty files?
Is that github just showing it odd in PR, and all you've done is change the permissions on the file?

cognifloyd · 2023-02-27T16:03:37Z

Yeah. That's just GitHub being weird as I only changed the execute bit, not the file contents. If you do a "view file" on those, you'll see the file contents.
