Description

This pull request is to replace a custom bot I wrote long time ago with a more standard actions/stale that is also used by sunpy.

Fixes #20478

Contributor

Thank you for your contribution to Astropy! 🌌 This checklist is meant to remind the package maintainers who will review this pull request of some common things to look for.

  • Do the proposed changes actually accomplish desired goals?
  • Do the proposed changes follow the Astropy coding guidelines?
  • Are tests added/updated as required? If so, do they follow the Astropy testing guidelines?
  • Are docs added/updated as required? If so, do they follow the Astropy documentation guidelines?
  • Is rebase and/or squash necessary? If so, please provide the author with appropriate instructions. Also see instructions for rebase and squash.
  • Did the CI pass? If no, are the failures related? If you need to run daily and weekly cron jobs as part of the PR, please apply the "Extra CI" label. Codestyle issues can be fixed by the bot.
  • Is a change log needed? If yes, did the change log check pass? If no, add the "no-changelog-entry-needed" label. If this is a manual backport, use the "skip-changelog-checks" label unless special changelog handling is necessary.
  • Is this a big PR that makes a "What's new?" entry worthwhile and if so, is (1) a "what's new" entry included in this PR and (2) the "whatsnew-needed" label applied?
  • At the time of adding the milestone, if the milestone set requires a backport to release branch(es), apply the appropriate "backport-X.Y.x" label(s) before merge.

I think this is the only part I am not sure about. According to https://github.com/actions/stale documentation, update means comments too, but we don't want that. We only want the timer to reset on new commit. Is there a way to ask actions/stale to only count last commit timestamp of a PR?

Our current policy: https://docs.astropy.org/en/latest/development/maintainers/maintainer_workflow.html#stale-policies

I've had a think about this and I'm not sure there's a way around it. I think we should just accept that comments count and move on.


I did wonder if you could have a pull_request_target workflow which did nothing but remove the Stale label. But it wasn't clear to me from reading the actions/stale docs if that would actually work.

But then people (or non-people) can just type junk into a comment every so often to keep it alive, and that defeats the whole purpose of stale bot.

I don't like the idea of counting comments and IMO it's a blocker in my view. If you look at the usual stale PRs there is useless chatter on it even when it's clearly not going anywhere and should be closed.

So, does that mean we should abandon this idea and close the PR without merge?

It seems kinda mad to me to maintain our own custom rolled thing for what seems minor

I mean we can try, I just don't think it will be effective enough.

Our custom thing seems to be working and just the way we like it. Why swap it out for something less?

I updated the PR following #20601 and also updated the developer docs with what I think this new bot would do based on the settings here. Still not 100% sold.

I will resolve conflict from #20629 when we have a consensus to move forward.
