Migration to `pyproject.toml` #3338

hirosassa · 2025-01-19T07:11:35Z

Description

In this PR, I migrated from setup.py to pyproject.toml using uv.
Fixes #3327.

In detail I did followings:

migrate setup.py features to equivalent pyproject.toml
introduce uv as a package manager
move dependency configurations for test from tox.ini to pyproject.toml
update tox version to use new features of tox and pyproject.toml
drop Python 3.7 support. see: Migration to pyproject.toml #3338 (comment)

A part of codes are burrowed from @dlstadther 's branch.
ref master...dlstadther:luigi:migrate-setup-to-pyproject

Motivation and Context

python setup.py install is deprecated.

Have you tested this? If so, how?

CI worked.

dlstadther

Awesome start on this! I really appreciate your active involvement. My time is too unpredictable to spend significant dedicated time to this project.

pyproject.toml

+common = [
+  "pytest<7.0",


I have 2 preferences here related to sorting:

keep package names in alphabetic order

keep group names in alphabetic order

This makes it easiest for humans to view and also to maintain order where new packages should be added.

+jsonschema = ["jsonschema"]
+prometheus = ["prometheus-client>=0.5,<0.15"]
+toml = ["toml<2.0.0"]

+[dependency-groups]
+dropbox = [


(This comment doesn't need to be addressed as part of this PR; mostly just thinking aloud)

Perhaps it makes sense in the future to move some of the dependency-groups content which is used for unit test execution for specific luigi modules (particularly the contrib and optional stuff) out of dependency-groups and into project.optional-dependencies to facilitate luigi installation with "extras". These extras can also easily control the cases where the luigi module may only support up to a max version.

Food for thought if it changes how you design/organize this file.

tox.ini

+requires =
+    tox>=4.22 # `dependency_groups` needed
+    tox-uv>=1.19


Could you help me understand why these requirements are here and not in pyproject?

In general case, tox version is not managed in pyproject.toml, requirements.txt, etc.
https://github.com/tox-dev/tox-uv/blob/main/.github/workflows/check.yaml#L40
https://github.com/tox-dev/tox-uv/blob/main/tox.ini#L2-L4
I think this is because tox is not related to actual implementation of tests.

In our CI, we use dependency_groups feature of pyproject.toml and tox, so I added this requirements on tox's configuration.

Before merging, we'll need to identify how to verify the merging of the final version of this branch doesn't break Luigi's readthedocs.

@hirosassa , how you thought how we can be sure that we don't break RTD when merging this PR?

I think it is a little bit difficult because it depends on webhook of this repo.
I confirmed that a local build of documents using Sphinx is succeeded.

@dlstadther I confirmed CIs are all green without Python 3.7.
see: https://github.com/spotify/luigi/actions/runs/13086373164/job/36517994352

With Python 3.7, test fails in code below:
https://github.com/mysql/mysql-connector-python/blob/8.0.33/lib/mysql/connector/connection_cext.py#L291
https://github.com/spotify/luigi/actions/runs/13086478927/job/36518207022?pr=3338#step:6:166

I think the root cause of this problem is Python 3.7.9 runtime.
The succeeded case runs in 3.7.17.
https://github.com/spotify/luigi/actions/runs/12875540263/job/35897024647#step:7:19

The reason why the CI in this PR for Python 3.7 run in 3.7.9 is uv supports only 3.7.9 for Python 3.7
We cannot use newer Python with uv because uv using python frompython-builds-standalone and it dropped Python 3.7.10+ support.
https://github.com/astral-sh/python-build-standalone/releases/tag/20210103

We might need to consider dropping support for Python 3.7.
Do you have any idea solving this problem?

With 3.7 already EOL for awhile I think it's fine dropping support.

dlstadther · 2025-02-02T01:52:57Z

Looking at https://pypistats.org/packages/luigi , there are still 3.7 downloads, but fewer than 3.8+. I'm in favor of removing 3.7 support

hirosassa · 2025-02-02T02:00:12Z

@dlstadther @RRap0so Thanks for your comment!
Let's drop Python 3.7.

hirosassa · 2025-02-02T02:39:52Z

@dlstadther This PR is ready for review!

RRap0so · 2025-02-03T14:54:25Z

We probably need to drop the checks for 3.7 but I'm wondering why there's 3.8,3.9 even 3.10 checks not being reported?

@hirosassa can you take a look at the changes? Something is up, some checks haven't ran.

I can remove the 3.7 checks once this is good to go.

hirosassa · 2025-02-03T20:56:47Z

@RRap0so Thank you for your comment!
This is because I changed environment matrixes changes, for example for simplifying environment specification.
So we should follow repository setting of "must pass CI".
You can fix this on settings > branch > master > edit > Require a pull request before merging > Status checks that are required.

dlstadther

A few comments/questions.

Also, we'll need to have the merge approval settings updated by @RRap0so .

@dlstadther ping?

dlstadther

I think we're good to go here, @hirosassa . While i'm unsure what the behavior of the RTD will be since it failed a few years ago, but everything i can find related to RTD suggest they're on recent ubuntu now (which should support luigi installation just fine).

Lastly, we will need @RRap0so 's help to update the required CI checks to allow merge.
