🧵responses please to not detract from the current convo - I'm looking into a temporary workaround for this issue, specifically I need to set

DJANGO_SETTINGS_MODULE

for specific directories / per-

python_tests

. Maybe someone has a solution for this? I've made some attempts with pytest hooks to no avail

Hello, a proposal to support per-tool lockfiles and a first draft of multiple lockfiles for user code. Unlike the current constraints.txt approach, this uses actual lockfiles with hashes and that must be fully comprehensive. Pants will generate them for you Feedback welcomed: https://docs.google.com/document/d/1bCYb0UQZx9a-9tAagydCN_z3826QRvz_3aVnXKSNTJw/edit#

Hey folks. We've created a testimonials page on the documentation site, so readers can get a feel for some of the benefits Pants can bring them: https://www.pantsbuild.org/v2.5/docs/testimonials . We'd love it if you can provide your own content for this page. Let me know! Thanks.

Hey all, I’m wondering if there’s any way to override subsystem configs per target? In my specific case, I’m trying to add some extra environment variables to a pytest run. But it seems like this might be generally useful? I recall when using Gradle that most tasks are setup to take their defaults from an extension (think subsystem config), but then each value could be overridden on the individual task. Thanks for an awesome tool btw!

Hi Team. Any idea how I can overcome this issue. (I use Python 2.7.15rc1, and upgrading it is not an option right now):

root@92544bc397ef:/build# ./pants --version
New python executable in /root/.cache/pants/setup/bootstrap-Linux-x86_64/pants.TsgPCU/install/bin/python2.7
Also creating executable in /root/.cache/pants/setup/bootstrap-Linux-x86_64/pants.TsgPCU/install/bin/python
Installing setuptools, pip, wheel...done.
Collecting pantsbuild.pants==1.0.1
  Could not find a version that satisfies the requirement pantsbuild.pants==1.0.1 (from versions: )
No matching distribution found for pantsbuild.pants==1.0.1
./pants: line 84: /root/.cache/pants/setup/bootstrap-Linux-x86_64/1.0.1/bin/pants: No such file or directory

Given this file structure, how can I read the contents of the setup.cfg file in a plugin, given that I have the

request.target.address

of the BUILD file? I've tried using

await Get(DigestContents, ...)

targeting a PathGlob to that file path, but it causes infinite errors complaining about the file system changing 🤔

Anyone experience for poetry and pants?

I have a target depend on a complex (in house package), it works on

test

(load and list out version) - but when using the same test goal with

repl

It said

AssertionError: Failed to cache distribution: .deps/idna-2.10-py2.py3-none-any.whl

Any idea how I can go deeper on this?

Hi everyone! First of all thank you so much for pantsbuild, we’re using at my company and it is a joy to have a mono repo built with speed and confidence! I’d like to ask for some thoughts (I’m likely doing something wrong or just plain silly). My stack: • Running pantsbuild 2.20 with python 3.7.7 on linux with a private gitlab CI runner on docker executor • Pants cache is shared with the docker executors via a host directory mapping mount (instead of using gitlab CI’s cache: feature because it’s too slow for large caches) • Runner concurrency is set to 1 (only one pants process running per executor) However I’m running into to some random issues that randomly happen and get retried by the CI but are very hard to reproduce: • During pip dependency resolution, I often get:

Exception caught: (pants.engine.internals.scheduler.ExecutionError)

after it logs

Completed

. It also errors with

ProcessExecutionFailure: Process 'Resolving 14 requirements … failed with exit code 1.

and

exited with -9 and STDERR: None

• Just after running

./pants package

it randomly crashes with

Exception: Failed to begin read transaction: Resource temporarily unavailable

- I check ulimits for my docker daemon and most values are unlimited so I’m not sure what other resources could be starved thanks!

is it possible to change the output directory for

./pants package

?

OK, new question on `python_requirements`: one of our desired lambda functions uses

pydantic

which insists on lugging along its 60MB (!) of binaries. I would like to install it as

--no-binary

if possible, which supposedly gets it down to about 6mb, much nice to fit under lambda requirements. I would ordinarily, apparently, put the line

--no-binary=pydantic

in the

requirements.txt

in addition to

pydantic==1.8.1

, but I've tried a few permutations and I think pants just doesn't like that sort of thing. Is there a way to do it with

python_requirement_library

or some such?

https://pantsbuild.slack.com/archives/C046T6T9U/p1620315506324900 ^^ hello pants people, may I have some advise on this 🙂

When using

pyproject.toml

for

black

configuration, is there a way to run

fmt

only against the file patterns in the

include

attribute?

Is there a way to use multiple pants.toml's? Let's say, for example, I have

/pants.toml

,

/src/python/project_a

,

/src/python/project_b

. What I'd like to do is have different configurations for those projects for various tools, and ideally a "fallback" default. From what I can tell a single toml file must specify all of the config paths for various tools, based on

Config files must be explicitly declared

in the docs - so I was wondering if instead it might make sense to just use multiple tomls instead?

As one example - passing different flags to

pytest

for different projects. Some projects may have coverage requirements, others may not.

mypy

config is another example.

I am trying to have one pex_executable for a file and a folder, however the folder is not packaged into the pex file. How do i explicitly tell pants to load the folder as well?

Hello everyone. I am trying to better understand how pants utilizes its dependency cache. I am running pants 1.30.4 (hopefully for not much longer as 2.x upgrade should be very soon). When i look in our cached dirs i see things like this. Shown below are two diff UUIDs that have the exact same requirement downloaded into the cache. I am trying to solve for an issue we are having where our cache is massive. We run ~25 docker containers that all share a volume mounted cache with the host. Each container is a “pants base image” that has an entrypoint to a pants run command. Any insight as to why this may be happening or what we can do to optimize would be helpful. It almost looks as if each docker container has its own cache for dependencies regardless if it is running something that should be already cached.
