One pager for file system specs, particularly how rules will consume this. I bolded the two key arguments I’m making. Thoughts appreciated! https://docs.google.com/document/d/15xphZcFnowytF0Qu2sO1PG7wHAWoyLof7hK0jVa5T8E/edit#

one big comment

Benjy and I were discussing. It boils down to this question: what should

./pants test src/python/pants/rule/core/fmt_test.py

do? Should it run every test in the target or only

fmt_test.py

? We both agree that it should get the owning target of

fmt_test.py

to calculate all the target info like dependencies, but it should only run tests on

fmt_test.py

, not

lint_test.py

etc.

sure. the former thing is "owner-of". if the goal is then able to further filter based on the filename being used, that's a bonus
