I want them all! 😉

Is there a way to ignore watching a single directory while running pants (place to keep docker volumes to preserve state).

Hello, apologies if I missed this in the docs, but is there a way to limit pants to specific python resolve when testing? We are using multiple resolves for common code with

parametrize

, but pants ends up running tests for every resolve. We really only need to run them once.

Hi team, is there a way that we can run pants with multiple pytest arguments? According to the official document, I need to use “--” to pass the arguments to pytest. If I try it with only one argument, it works. But with multiple arguments, it failed… for example:

./pants test t.py -- --name "Ben" --age 30  --year 2017

?

Hi, has anyone had success running

pylint-pytest

when there is two different source roots with python in it. When i restrict the glob to just a single one of the sources, it passes, but it fails when both run.

Does anyone know what this error means?

╰─ pants lint mtom                                                                                                                                     
17:18:07.38 [ERROR] 1 Exception encountered:

The code can be found in my pants playground located here: https://github.com/xuru/monolith-to-monorepo/tree/pants_baseline

Hi everyone - for anyone interested in pex, wanted to share this blog post about how we use pex files with warm docker containers for fast deploys: https://dagster.io/blog/fast-deploys-with-pex-and-docker

Has anyone been able to use

vcs_version

with

go_package

? Seems like it doesn’t infer the codgen’d go package dependency and explicitly stating the dependency doesn’t work either

If I write a plugin to compute docker image tags as in https://www.pantsbuild.org/docs/tagging-docker-images#providing-additional-image-tags-with-a-plugin How do I access

{pants.hash}

?

Is it a bug that you first generate a lockfile and then on the same machine you try to run tests it fails on, or is this somehow expected and we should generate lockfiles differently?:

What did you want to know specifically about the Go support?

What interests me here really is what the future might hold for Go toolchain management by Pants. It seems like this might be the answer, which seems like it gives parity with what Please currently does:

I wanted the Go backend to just have an equivalent to what

pyenv

,

coursier

, and

asdf

do and download and install the Go SDK into a Pants-managed directory.

Correct me if I'm misinterpreting what you've said, but otherwise this seems promising and thanks for the responses!

I am trying to pass an envirnmental variable from the host system to the docker build process through pants (on bitbucket pipelines). Specifically the DOCKER_HOST variable, by adding this to pants.toml

[docker]
env_vars=["DOCKER_HOST"]

But when I run

pants -ldebug I get package ::

, I see in the logs an entry which seems to show the environmental variables passed to the sandbox, but DOCKER_HOST is not there (the full log entry is in the thread). Do I need to do anything else to pass it through?

I am suddenly experiencing this error

/tmp/pants-sandbox-NXZ1ts/./django.pex_pex_shim.sh: 2: set: Illegal option -o pipefail

no matter what command I am running. Ideas? I already tried

--no-pantsd --no-local-cache

. Using

2.15

.

Hello everyone! So I’ve finally gotten to the point where I gave up last time. I have a django project with the tests inside of the each of the django apps, and the configs/settings at the top of the repo. When I run the tests, I get the following error:

ImportError: No module named 'config.settings'

pytest-django could not find a Django project (no manage.py file could be found). You must explicitly add your Django project to the Python path to have it picked up.

Here is the repo in question: https://github.com/xuru/monolith-to-monorepo/tree/pants_baseline If anyone could give me some pointers on how to make this work, I would much appreciate it!

Dumb question: Can one make variables in build files then interpolate strings?

Can one combine resources with http_source?

resources(
   name="foo"
   sources=[http_source(...),http_source(...)]
)

This is telling me that I need a list of strings.. =/

When using an http_source I am seeing an issue where the size is larger than expected.. using curl I get one size, downloading local I get another size.. can I make pants tell me the size it received?

Can I reference a local target in a BUILD without the full path? In bazel.. //foo/BUILD

thing = ":bar"
thing2 = "//foo:bar"

Are the same label, as bazel knows where I am..

Can we isolate builds from the network? Like bazel sandboxes can do.

is there a way to exclude a package being installed from the lint / check / test steps? torch is breaking my builds when it tries installing my full universe of deps

I'm having the hardest time getting google.auth.credentials|default|.. to be infered. Is there a way to force this? I have added it as an explicit dependency to the python_sources 🤔

How can I get vscode to pick up

dist/codegen

? 🤔

Is it possible with target selection to build everything BUT some list of targets? I am thinking about how to parallelize the build jobs on CI.

Im currently on an M1 mac and this error presented itself after pulling down code from another colleague, however there were no major code changes. Has anyone encountered this before?

Hello again! So, I’m having a hard time getting tests to run with django. The repo is here: https://github.com/xuru/monolith-to-monorepo/tree/pants_baseline, and this the error it’s giving me:

ImportError: No module named 'config'

pytest-django could not find a Django project (no manage.py file could be found). You must explicitly add your Django project to the Python path to have it picked up.

Somehow pytest-django can’t figure out where

config/settings

is? Any help is appreciated!

Hi all, is there a way in pants to ignore a change to a specific file so a running pex doesn’t restart?

Hi all, we have been setting up a mono repo (all python) with Pants and are having some trouble figuring out how we ought to get Pants to construct the parts of the code we'd like to distribute. (Help needed!) I've put the full details as an in thread reply.

Has anyone tried to get the Pants .gitignore put into the main Github gitignores? https://raw.githubusercontent.com/github/gitignore/main/Python.gitignore

added an integration to this channel: linen.dev

Hi! I’m trying to setup debug adapter with pants. From

./pants run --debug-adapter                          
17:15:06.43 [ERROR] 1 Exception encountered:

  NoApplicableTargetsException: No files or targets specified. The `run` goal works with these target types:

  * docker_image
  * pex_binary
  * python_source
  * python_test

it seems like the

pex_binary

is supported, but when I actually run the command with a pex_binary target, I got this error

Debugging a `pex_binary` using a debug adapter has not yet been implemented.
