How can I get the caller's CWD in rule code? Normally we assume project root, but I wanna handle

../../pants arg1 arg2

I might need someone with a Mac to help me debug the failure on this PR: https://github.com/pantsbuild/pants/pull/17563

I’m getting the following error on

main

when I try to build a

deploy_jar

. Any ideas?

FileNotFoundError: [Errno 2] No such file or directory: '/Users/chrisjrn/src/pants/src/python/pants/jvm/jar_tool/src/org/pantsbuild/args4j'

looks to be related to a change @witty-family-13337 made recently

yay, the new visibility rules are better at catching violations than the previous hand-crafted check! 😄

20:14:59.30 [INFO] Scheduler initialized.
20:15:01.63 [WARN] Dependency rule violation for src/python/pants/goal/explorer.py on src/python/pants/backend/explorer/server/uvicorn.py
20:15:04.43 [INFO] Completed: Typecheck using MyPy - mypy - mypy succeeded.

^^ introduced a bad import in core on the backend code…

@curved-television-6568 and @careful-address-89803 : Here is a first pass at allowing the python dep inference to use the new dependency rules feature to disambiguate possible deps.

Can someone help me answer a question about

<http://binaries.pantsbuild.org|binaries.pantsbuild.org>

? Trying to see if we can configure a redirect. Specifically, for the SHA->wheel lookup, we use the pants version. However there's only ever one version per SHA. So Ideally we could configure a server redirect to serve

index.html

at the SHA "folder" as well and bypass needing the version (but keep it in for backwards compatibility). CC @witty-crayon-22786 @happy-kitchen-89482

IIRC

<http://binaries.pantsbuild.org|binaries.pantsbuild.org>

is an S3 bucket, and S3 doesn’t support symlinks, so…

I was thinking more along the lines of a server config? I know little here, but does cloudfare allow redirect ruleS?

Can someone approve https://github.com/pantsbuild/pants/pull/17584?

It does, I believe, but I’m not sure that traffic goes through cloudflare?

@witty-crayon-22786 Hi, if there’s time I’d like to finish up and land https://github.com/pantsbuild/pants/pull/17588 if possible for the 2.16.0dev0 release, as it potentially changes the semantics of the visibility rules 🙂

hey folks, is it me or the CI is not feeling great today? 😕 https://github.com/pantsbuild/pants/actions/runs/3504431134/jobs/5871384993 tried to re-run failed jobs multiple times and same error

This’ll be pretty sweet.. 🙂

heyas, I'm working on helpers for lockfiles, trying to reduce the small differences between some of the tools. The Mypy and Black plugins are slightly different from the others (flake8, pylint, basically everything else): They skip checking the code's interpreter constraints if a nondefault value is specified for

interpreter_constraints

(link). This is distinct from the similar (?) check done in the

PythonToolBase

(link) (link to issue discussing this) Questions: Is it still necessary to do this check in lockfile generation? What effect does this actually have, given the additional check? Should the other tools do this check as well?

Hmm… seems the cache for the build-wheels GH action is over 4 GB in size.. (

Cache Size: ~4526 MB (<tel:4746103636|4746103636> B)

) which takes ~9.4 minutes to download at 8 MB/s.. is it worth it?

Periodic update: • immutable inputs is mostly done, blocked by... • marking pants as an explicit namespace package is done but blocked by... • moving VERSION file is done, just waiting one PR because it's been painful in the past No other plans for Pants on the horizion

• Python lockfile targets are a thing now (along with the new Synthetic targets API) • Jvm lockfile targets in prep.. HELP WANTED, I’m no Java guy 😉 • visibility rules has landed (with the Dependency rules API) - pending docs • explorer docs stubs in draft along with some activity for the explorer backend in prep for some frontend UI stuff.. 🙂 • lockfile diff for generated lockfiles in the works (w support for python (pex) and jvm (coursier) lockfiles) • `list-backends` goal is a minor feat, but I think is neat 🙂 • … have many more wishes to add on my TODO list, but alas, time is scarce..

📣 Pants Team members note: December's team meetup is cancelled so that everyone can enjoy their respective holiday seasons without distraction. See you at the next meeting, in January!

so, first thing I noticed is that pants pacakges for arm in PyPI are missing after 1.7.0.

From a colleague. I'm guessing from what I see we don't do manylinux arm?

@ancient-vegetable-10556: a random papercut thing for the

experimental_shell_command

list (which i think would be good in either a

Project

board or stabilization ticket): the

tools

list is required even if no tools are used (i.e. if all you need is

bash

itself)

OOps. I'm pointing the finger at me

Hmm oddly, using a PEX lockfile when locking

absl-py

it uses

absl-py==0.10

instead of

absl-py==0.10.0

. https://pypi.org/project/absl-py/0.10.0 lists

0.10.0

and the wheel's

METADATA

lists

0.10.0

🧐

@witty-crayon-22786 and @ancient-vegetable-10556 Should we just punt on directories in https://github.com/pantsbuild/pants/pull/17520? While we figure out the cruft, we can start removing

immutable_input_digests

, I think

hey folks, is it possible to get into a debugger when running

./pants

command with in-repo plugin code being executed? If I add

import pdb; pdb.set_trace()

inside my plugin code, I get

Exception: stdin is currently Exclusive owned.

in the terminal

when doing

print

from a `@rule`'s body, I get

21:02:46.12 [INFO] stdout: "hello!"
21:02:46.12 [INFO] stdout: "\n"

the

goal_rule

has fancy

from pants.engine.console import Console

, but how do I go about printing from the

rule

? 😕

All `__init__.py` file should be empty, but the following had content: src/python/pants/__init__.py

??

https://github.com/pantsbuild/setup/pull/136 is only failing on Mac. Anyone able to help me debug?
