sys.path

question: I am adding a new backend to Pants called

src/python/pants/backend/observability/opentelemetry

. I am seeing this backend shadow the actual third-party

opentelemetry

package though because the parent directory

src/python/pants/backend/observability

is in the

sys.path

when running tests and so an absolute import (

from opentelemetry import trace

) fails because of the shadowing. This parent directory is not a source root, is this expected behavior?

(This is all surprising me, and glancing at

src/python/pants/backend/

I'm double surprised we didn't hit it before.)

I don't think that is expected or desired, but I guess it's because that source root is just a bad choice for this test

My question is really understanding how

.

can even be a valid source root?

Remove it and see what breaks?

I didn't add any source roots though; there's nothing to remove which isn't already in

pants.toml

.

Python is the woooooooorst!
