If I request a

CoarsenedTargets

, how can I get back the original request targets from it?

.members

of each

CoarsenedTarget

that will potentially be a superset

if you have target A, and it is involved in a cycle with target B (i.e., they both depend on one another), then they will be the members of a single

CoarsenedTarget

so if you request

CoarsenedTargets

for target A, you’d get back A+B as the “root” members

So I need to pair field_set to the associated CT from the mapping then in my lint change

I'll give that a whirl

um, yea, possibly. the way to think about a

CoarsenedTarget

containing A+B is that they are essentially “indivisible” (which is i think what the docstring says)

when two targets are in a cycle like that, whenever they are built with dependencies, they must be mutually compatible

so their ICs are guaranteed to be compatible, their resolve is guaranteed to be compatible, etc

Yeah I'm trying to map this back to the existing pylint rule code. I think I have it mentally, we'll see how it goes putting pen to paper 🙂
