Looking great, thanks so much for your help here!

I've got a few questions / change requests!

[sydney-runkle]

Very odd that we're seeing benchmark changes here...

Very odd that we're seeing benchmark changes here...

Benchmarks seem to be broken as they did not run and thus codspeed is for some reason reporting non sense results

[sydney-runkle]

Maybe bumping to v3.0.0 will help...

I don't have any clue why benchmarks are changing here, I was looking for a fix.

[sydney-runkle]

Fixing the codspeed issue, hopefully :)

[frfahim]

There is a conflict with pdm lock file, should I rebase it?
btw, CI's are not running.

[sydney-runkle]

All good, I can take it from here. Thanks!

[frfahim]

uv automatically checks requires-python constraints and use that python version. Is it necessary to mention the python version again here?

[sydney-runkle]

It does seem redundant...

[Viicos]

So the thing is uv will prefer the specified version in the .python-version file if present, no matter the previously installed version. We currently don't have such a file, but it could be pretty bad if we end up creating one at some point, especially for the jobs with a Python version matrix: CI will only run on the version from .python-version, and we won't notice anything.

It's a bit unfortunate, probably using tox (and tox-uv) could help.

[frfahim]

when a python version matrix exists, then python version is specified with the sync command
uv sync --python ${{ matrix.python-version }}

So it will use the requested python version from matrix even the .python-version file exist

[Viicos]

Seems like in some CI jobs, we run uv install ... and then uv sync ..., and in others we only run uv sync .... uv sync should call uv install right? Maybe it's best to be explicit and have a uv install ... step for every job

[frfahim]

uv sync command is used everywhere, there is no use of uv install command in the CI's

[sydney-runkle]

I've removed the unnecessary installs :)

[sydney-runkle]

Unclear to me why that test is failing... investigating now.

[sydney-runkle]

@frfahim,

Any chance you could take a look here?

[frfahim]

Sure, investigating the issue 👀

[sydney-runkle]

Looks like we're installing an older version of Python 3.9 - not sure why - previously, it was 3.9.20, now it's 3.9.6 without the manual install before the sync.

[frfahim]

It's using system python version, for macos 13 (with 3.9) it is 3.9.6

Run uv sync --python 3.9 --group testing --extra timezone
Using CPython 3.9.6 interpreter at: /Applications/Xcode_15.2.app/Contents/Developer/usr/bin/python3

It looks like it's not using uv installed python version for macos 13 with 3.9

This command will fix the issue, but I am looking for a better solution
uv sync --python ${{ matrix.python-version }} --python-preference only-managed

[sydney-runkle]

Thanks so much!! Great work!
