Are relative imports supported for dependency inference? (e.g.

from .subfolder import something

vs

from module.subfolder import something

?)

Yes, they are: https://github.com/pantsbuild/pants/blob/1c76ec0ada3d6d06d01413ef14222b19cff65833/src/python/pants/backend/python/dependency_inference/import_parser_test.py#L121-L141

I think I'm encountering something like this:

# module/__init__.py
from .api import PublicThing

# module/api.py

SECRET_THING = 123

class PublicThing:
    pass

# tests/test_module.py

from module import api
print(api.SECRET_THING)

This used to work

Oh, that would be this horrible gotcha, the tooltip about init.py https://www.pantsbuild.org/docs/python-backend

Any downside to turning this on?

It can: https://github.com/pantsbuild/pants/pull/10813, but almost certainly worth turning on in your case

k it does fix this issue

fyi https://github.com/pantsbuild/pants/issues/10823 tracks removing this gotcha

fyi - I can't remember any python projects that do not put stuff in at least some of the

__init__.py

files...
