https://twitter.com/pantsbuild/status/1311063685557673985 Pants 2.0.x is now part of the remote-apis-testing suite, confirming that the Rust engine is compatible with the major Remote Execution API servers. Hooray standardization! https://t.co/PC0t6hTKgS #monorepo #python Twitter

How does one write a unit test for a custom subsystem (i.e. a class that inherits from

from pants.option.subsystem.Subsystem

specifically, I need to have my

CustomSubsystem.global_instance()

method to not blow up. using

pants.testutil.option_util.create_subsystem

doesn't cause global_instance() to work. couldn't find any info in the docs: https://www.pantsbuild.org/docs/rules-api-testing (also note that the page title:

Testing plugins

doesn't match the url, ideally those should match)

Hello! We recently realized we have a couple distinct goals that all do a similar thing: create an asset from your code and write it to

dist/

. (

binary

awslambda

setup-py

, and

bundle

in v1) We’re thinking it would be clearer to consolidate them all into a new goal, possibly named

./pants build

. We’d love any feedback about this, including what you would think the name

build

means, e.g. if you would think it means “compile” some library code, for example. Or if you have suggestions for a more apt name.

is there any current place where plugins for v2 are being aggregated? Like a set of links to github/gitlab repos or something like that?

Timout question. Our private wheel repository is only available while on a VPN. I just noticed a

./pants binary

run going for over 1000+ seconds with no sign of stopping because my VPN had dropped. Is there a way to set a timeout for the "Resolving requirements" stage?

10/01/2020, 4:21 PM

I run

./pants setup-py gh/leader_election:cassandra

to test the syntax of my gh/leader_election/BUILD file

billowy-motherboard-58443

10/01/2020, 4:21 PM

and it complains

Copy code

NoOwnerError: No python_distribution target found to own gh/util/file_utils.py. Note that the owner must be in or above the owned target's directory, and must depend on it (directly or indirectly). See <https://www.pantsbuild.org/v2.0/docs/python-setup-py-goal> for how python_library targets are mapped to distributions.

10/01/2020, 4:21 PM

nothing in my leader_election nor its deps speaks of file_utils....

billowy-motherboard-58443

10/01/2020, 4:22 PM

so what is that message actually trying to say? And what happened to make it say that?

Hey y’all, thanks for your feedback on the

package

goal. One other disruptive change we want to do before landing 2.0: rename

python_binary

pex_binary

and
python_tests
to
pytest_tests
. Some reasons: 1. We likely want to support multiple binary formats and multiple test runners in the future, e.g.

pyinstaller_binary

. We should stop privileging the status quo. 2. More accurately model that Pants is an orchestrator for the tools you already use; we’re not inventing some binary format, which might be implied with the status quo. We know it’s disruptive. We’ll use a deprecation cycle + give a script or sed regex snippet to automatically fix this. Any thoughts on this?

How does one express "I depend on a package elsewhere in this repo, and at a particluar version of it" ?

I seem to be able to do the former in python_library.dependencies, but not the latter

10/01/2020, 7:59 PM

BTW - docs bug report: https://www.pantsbuild.org/docs/python-setup-py-goal (mentions namespace_packages=...) but that is appearently not legal at least with 2.0.0b2

With pants 1.30.1, I am getting the following error:

ValueError: '/Users/me/.pants.d/tmprshp3zu0' does not start with '/Users/me/dev/mymonorepo'

when I run

./pants repl

. I am still upgrading our

pants.toml

file from an earlier version, so it may have something to do with that.

FYI when running

pants --pants-bin-name="v2" --no-v1 --v2 "$@"

I got the somewhat cryptic error

pants.option.errors.ParseError: Multiple cmd line flags specified for option pants_bin_name in global scope

. Once I removed

--pants-bin-name

it worked. I did not actually check what value for

pants-bin-name

is getting set.

I started getting some errors when running my

pants test

not sure what happened.. the tests run for only one target (which passes) and then it shuts down… I’m using 1.30.2rc1 (was using 1.30.0 before)

While trying to troubleshoot a test, I found that I could no longer use

repl

on our 3rdparty libraries:

Copy code

This works on our main branch using 1.27. Did something change with how

pants

works with

python_requirement_library

target types? I am still upgrading our

pants.toml

file so it might be something there.

What is the magic incantation for nested namespace dirs?

billowy-motherboard-58443

10/02/2020, 6:02 PM

e.g. ns/core/leader_election/impl/zookeeper

billowy-motherboard-58443

10/02/2020, 6:02 PM

where impl is the init.py - less dir

billowy-motherboard-58443

10/02/2020, 6:02 PM

(aim is to create a publishable pkg of ns.core.leader_election.zookeeper)

that is unexpected. even more unexpected is that it doesn’t work on 2.0.x either
