I'm on release duty today for 2.16.0.dev5. It looks like there are no unhandled deprecations; so I'll just proceed with a bump + changelog PR this afternoon.

The macos wheel build thread leads me to believe that we should start pushing hard on scie-pants. Which as far as I can tell just means loudly advocating for people to try it, and make it trivial to do so.

To that end, the pantsup script: https://github.com/pantsbuild/setup/pull/137

"Pulls your pants up!"

I would like to then change our docs to recommend trying this out preferably to other ways of installing Pants.

Hacking on the explorer graphql API (and frontend)

And today's installment of WTF GHA: https://github.com/pantsbuild/pants/pull/17997

Go lang update: 2.16 has some big in-progress changes where Pants will build the Go SDK packages instead of relying on prebuilt package archives. (Go v1.20 will no longer ship with the prebuilt package archives.) Current PRs awaiting review: • https://github.com/pantsbuild/pants/pull/17995 • https://github.com/pantsbuild/pants/pull/17993 There are a few more PRs to land after that to complete the support (mostly for cgo to continue to work). Is there another 2.16 dev release to go or will next release be the 2.16 alpha? (I'd like to finish this work before the alpha.)

Generating docs for release seems to be incredibly flaky - on the readme side. I get either a 401 at some point deep into the process after the "Deleting doc ..." and in the middle of the "Creating / Updating doc ..." or else - sometimes:

Error getting URL: <https://www.pantsbuild.org/v2.14/docs/options#addremove-semantics>

If the URL is <http://pantsbuild.org|pantsbuild.org>, a `doc_url` link might be using the wrong slug or the docs for this version might be unpublished. Otherwise, the link might be dead.

You can use `--skip-check-urls` to skip.

Is this a shared experience or news?

The link for resolves seem to be broken for JVM/scala when browsing 2.14 docs. https://www.pantsbuild.org/docs/reference-jvm#section-resolves Also the

jvm_artifact targets

link is broken https://www.pantsbuild.org/docs/reference-jvm_artifact It’s mentioned here https://www.pantsbuild.org/docs/jvm-overview#third-party-dependencies-and-lockfiles

@happy-kitchen-89482: new thread for: https://pantsbuild.slack.com/archives/C0D7TNJHL/p1673962973223469?thread_ts=1673625363.306339&cid=C0D7TNJHL

Anyone have a custom formatter/fixer/linter using 2.15 and mypy? I'm getting

Name "MyClassName.Batch" is not defined

from:

class MyClassName(FmtTargetsRequest):
    ...

oddly, declaring

x: FmtTargetsRequest.Batch

makes

mypy

happy I'm also trying with

0.961

which is the version Pants uses in-repo

Can I get a review on this cherry-pick to 2.15 https://github.com/pantsbuild/pants/pull/18030 ? I am wanting to test pyright on 2.15 and this blocks that.

I notice that publish-tag-to-commit-mapping fails consistently, e.g., https://github.com/pantsbuild/pants/actions/runs/3955288009/jobs/6773444569

I can't seem to run Pants commands without go installed...

For the upcoming Pants contributor meeting, please reply in thread with any changes of note you'd like shouted out or slightly elaborated on since last meeting! 🧵

Is anyone currently working on an

audit

goal? https://github.com/pantsbuild/pants/issues/16495 I'm looking to add pip-audit support and it seems this is a sensible prerequisite.

Can anyone help me understand if this

filter

option is used at all for calculating the coverage at all? I tried the usual ctrl+f to find it and I don’t see where it’s being used. https://github.com/pantsbuild/pants/blob/main/src/python/pants/backend/python/goals/coverage_py.py#L129

@wide-midnight-78598: it took way too long, but i finally got around to refreshing the Plugin API Stability project, including doing a bit of triage to prioritize things.

Sorry in advanced for the merge conflicts that might arise in the coming days. I'm working on some housecleaning I've been meaning to do: • Working towards no implicit string concat • removing

frozen_after_init

There's never a good time to do this, so it was bound to painful whenever. So, sorry again 🙂

Why are we turning off the

cov-report

output generated by

pytest --cov

? I don’t understand what’s the point of then even running

pytest --cov

? https://github.com/pantsbuild/pants/blob/main/src/python/pants/backend/python/goals/pytest_runner.py#L359 I think this is the reason behind this issue

PR for documenting scie-pants: https://github.com/pantsbuild/pants/pull/18056

Why does it takes so long to run pants test itself? It’s still running

./pants --changed-since=8553e8cbc5a1d9da3f84dcfc5e7bf3139847fb5f test 
208.41s Run Pytest for src/python/pants/backend/python/goals/coverage_py_integration_test.py:tests

📣 Reminder: due to a schedule change earlier this month, Pants Team meetup for January is today! Team members, please check your calendar for the updated invite and agenda.

Hey folks, there are a few PRs that need cherry-picking into 2.15.x. Please go to https://github.com/pantsbuild/pants/pulls?q=is%3Apr+is%3Aclosed+label%3Aneeds-cherrypick, find your PRs, and cherry-pick them.

@happy-kitchen-89482 could you please create Readme pages for the tutorials on writing plugins No 2 and 3? https://github.com/pantsbuild/pants/pull/17890 (

integrate-new-goal-with-the-repository

) and https://github.com/pantsbuild/pants/pull/18018 (

testing-custom-plugin-goal

), respectively. Once the pages are there, I can add the page headers in markdown for them before cherry-picking into the

2.15.x

Is it a 🐛 that

Target

doesn't use

plugin_fields

or

name_explicitly_set

in `hash`/`eq`?

Oh TIL: Non-frozen non-dataclass subclasses of a frozen dataclass superclass are unfrozen: https://github.com/python/cpython/pull/6148
