Use uv

[gforcada]

On jenkins jobs, this simplifies so much the management of python versions that we can even test it directly on python pre-releases (3.14a4 right now) 🌟

[gforcada]

We need to install uv on Node5 though, @petschki are you responsible of it? 🤔

[petschki]

Yes. Will do today.

[petschki]

Done on Node 5 ... also installed /srv/python3.14

[gforcada]

Oh, you don't need to install it, uv takes care of it ✨

[petschki]

Ok ... thats nice 👍🏼

Looks good to me. Hard to really say without trying it for real. I must say I have not tried this part of uv yet.

Also, 3.14 will fail for any Plone version. Zope needs to be updated, and before that AccessControl, RestrictedPython and other zope packages with C code need to be updated.

I would factor the virtualenv creation into a separate script that can be called from the others -- but it's short enough that it's fine either way.

To summarize my code comments: It is enough to do

UV_PYTHON={py}
uv venv
uv pip install -r requirements.txt
uv run buildout ....

[davisagli]

Really I think you can just do:

uv run -p {py} --with-requirements requirements.txt buildout ...

[jensens]

As a one shot as it is in Jenkins, yes. Or uvx -p {py} --with-requirements requirements.txt buildout ... to reduce it to the max ;)

[stevepiercy]

Kind of off-topic, but does uv run -p {py} --with-requirments ... use uv's pip API? I couldn't find the answer in the reference docs for uv-run. I assume that it does not use the pip API, since it's not mentioned in this context.

I recently switched from the pip API to using uv directly in Plone Sphinx Theme, and now I feel like a big boy.💪

[davisagli]

@stevepiercy No, I don't think so. My understanding is that uv run will automatically create a virtualenv using the dependencies specified in the command (using --with or --with-requirements) or dependencies specified in pyproject.toml.

The uv pip commands are meant for interoperating with other tools that expect things like a virtualenv in a specific location, or a requirements.txt file instead of uv.lock.
