pantsbuild #general

will take advantage of your cores if it is capable of doing that: we configure the concurrency of tools that we know have concurrency flags, but many have reasonable defaults

I see, concurrency is being handled by the tool, and not

pants

in this case, yes: there is a mode for

lint

that will toggle “lint per file”, and in that case you would get ~1k

yapf

processes. we really ought to have an in-between toggle that would lint in batches.

but yea: it should likely be adjusted to batch.

If performance is equivalent, it'd be nicer UI/UX IMO to batch

Just added

requirement_constraints = "constraints.txt"

and saw

ERROR: Constraints cannot have extras

the output wasn't very helpful (I'll file an issue) but I think the offender is

marshmallow-dataclass[enum,union]==8.5.3

. The file was generated by

pip-compile

Hello guys, this is Xiaotong from Houzz, pretty new to the Pants community, I am using pants to build our python internal service and I got this error in my local, my mac version is

10.14.6

, does anyone have idea to fix this? 😄

Copy code

Learning from users: what are the most time-consuming challenges you have to meet along the way to fully adopting Pants, beginning from the "Hmm, a monorepo might be useful…" starting point? Where along the way are you most likely to meet with extended delay? If you had a magic wand, what pain point in that would you choose to have magically resolved? Thanks for helping us learn more about the big picture you deal with, and consider ways we might be able to help you more. 🙂

Is there a way to filter with

changed-since

and target type at the same time?

I'm trying to set up IntelliJ IDEA 2021.2.3 with the latest (unreleased) version of the Pants Plugin with Pants 1.27 for a Scala project. I used to get a "Debug with Pants" icon next to Specs2 test files, but this no longer seems to be the case. Any idea why?

Looking for a little guidance on building a docker target (details in thread)

stale-nightfall-29801

BUILD:

Copy code

python_library(

)

python_tests(
    name="test",
    sources = ["test/test_*.py"]
)

pex_binary(

    entry_point="bar/server.py:main"
)

docker_image(
    name='docker',
    sources=["Dockerfile"]
)

Dockerfile:

FROM python:${VERSION}
ENTRYPOINT [ "/bin/server" ]
COPY server.pex /bin/server

What happens if you add an explicit dep from the

docker_image

target onto

:server

? It should be inferred, but let's find out

stale-nightfall-29801

10/27/2021, 3:51 PM

@happy-kitchen-89482 you mean

bar

like so:

Copy code

docker_image(
    name='docker',
    dependencies=[":bar"],
    sources=["Dockerfile"]
)

stale-nightfall-29801

10/27/2021, 3:52 PM

it still cant find

bar/server.pex

server.pex

I'm trying to build a python distribution with some C bindings so have a

setup.py

file. The

python_distribution

also has

dependencies

on the target. They don't seem to be in the environment when

setup.py

is invoked? is there another way to get access to the libs e.g

numpy

Any tips on receiving an IO error when trying to wrap up

requirements.txt

for a large set of deps? Currently seeing
