pyproject.toml does not contain a tool.setuptools_scm section

[mtelka]

I'm packaging various Python projects for OpenIndiana. The packaging (and especially testing) is done in real environment with possibly many unrelated packages installed to make sure the packaged project works properly once it is installed.

When I try to work with a project that does not use setuptools_scm and setuptools_scm is installed then I see this warning:

[10/08/23 10:00:26] WARNING  pyproject.toml does not contain a tool.setuptools_scm section                                  setuptools.py:119

The warning is seen in many logs, including testing log. This causes a problem to us because it raises errors when we compare test logs between test runs. Yes, we could add a special rule to our testing logic to filter out this warning, but since this is a regression from setuptools_scm==7.1.0 then I'd prefer to see it fixed/changed at the setuptools_scm side.

Possible solution would be to change log.warning(e) to log.debug(e) in the setuptools.py file. If that's not possible or desirable then what about to implement some way how to silence the warning using an environment variable?

Thank you.

Would a log level of info be sufficient?
If its debug it might get lost in the noise

[mtelka]

I just tested and yes, log.info is enough.

What is the reason why this log entry is written (warning level or not)? Does it check if setuptools-scm is listed in build-system.requires?

Sorry, but 517ed80 is still wrong: when my project doesn’t use setuptools_scm at all, why it is even activated, and why is my logging (in whatever level) spammed at all? This is just wrong from the beginning.

Setuptools has no safe way to control the file finder entry point

I am sorry, but could you elaborate a bit, I really don’t understand what do you mean and how it is relevant to my complaint?

[RonnyPfannschmidt]

Setuptools always considers all plugins, there's no way to opt out easily

You shouldn't be seeing the indo log in most cases

If you do please elaborate on environment and context in a new issue
