hey, is it okay to delete

.pants.d/

and

.pids/

frequently (it creates many many files). Is it a good idea to add these directories to add to

nuke_if_too_big.sh

but with the file count instead?

I have a few questions about the file system stuff: • what is the difference between what goes into

~/.cache/pants/named_caches/pex_root

and

~/.pex/

? • is there a way to set where

named_caches/

,

lmdb_store

go? e.g. somewhere on NFS

interesting behaviour with isort:

./pants fmt :: --no-pantsd

with

# pants.toml
[isort]
config = "build-support/pyproject.toml"

is different from

isort --settings-path build-support/pyproject.toml

sorry

isort . --settings-path build-support/pyproject.toml

Hello, I have been having trouble setting up pants on my computer, and this is the error: it seems im unable to import setproctitle even though ive verified on my local machine that it exists in both python2 and python3

can pants in CI run lint, typecheck and test in parallel (no pantsd involved)?

another quick question. let's say that i have

./pants \
  --changed-since=origin/main \
  --changed-dependees=transitive \
  ...

and a failing test CI runs -> fail I trigger manually a build -> pass Is there a way to say "changed since + transitive dependees + earlier failures" ?

i trigger a build in the CI

How would you specify the earlier failures, as a list of tests that are known to the caller to have failed? Or are you asking if Pants can deduce this somehow?

I was asking if there is a flag to enable this behavior in pants

the command below doesn't work, is there a way to say "run on the diff between the previous commit and this one"?

./pants --changed-since=HEAD~1 ...

Hey, I think I've discovered a bug! We have a pip dependency in a requirements.txt that has a >= for it's version, and newer versions don't support our (old) version of Python (3.5). It appears Pants is struggling to resolve the proper version supported by the selected python interpreter

I’m trying to run

./aiq pants --pants-runtime-python-version=3.6 test.pytest --test-pytest-coverage=src/python/aiq/datadog_metrics test/python/aiq/datadog_metrics::

on Jenkins and I’m seeing this error

I’m using pants 1.16 and coverage 5.3. I’m not sure what I need to change for this to work. Any ideas? Thanks!

Hey everyone, just qq.. when listing targets that are

files

(or

resources

) seems like the pattern

src/python/cool_thing:my_app

doesnt happen. I have some tags for

pex_binary

and

archive

and they return as I mentioned above.. but for files.. it’s returning like:

src/python/cool_thing
src/python/cool_thing/Dockerfile

before it used to be:

src/python/cool_thing:my_dockerfile

Hi folks. Assuming rc3 remains stable, we plan to release it as 2.0.0 tomorrow!! We're going to do some posting about it, and I've written up this initial launch post. Would love to get your feedback! https://docs.google.com/document/d/1GZqCxwBNblZ3GuVoDDYiaafl8UtwkGYvEr60a7F4qsY/edit?usp=sharing

Feel free to comment on the doc.

Docker and Pants question: Do you use a different

.pantsd

directory when running

./pants

in a Docker container? What about any

*.pyc

files created if you share your repo inside your container? Do you share your repo inside your container?

another fun question... is there a way to make

./pants package

exit cleanly even if it finds no targets? i'm running

./pants --changed-since=$COMPARISON_TARGET --changed-dependees=transitive package

and I want it to be okay if that doesn't match any targets

Hello all! Today is the day we release Pants 2.0.0 and officially announce a stable Pants v2 to the world!

We'll be putting up a launch post later today (I'll link here), and when we do we'd appreciate your help in spreading it and getting the word out!

Yay! Congrats everyone 😄

what is the

.pids

dir used for? is this something that needs to be mounted when docker runs?
