Handle more cases in cfg_accessible by Urgau · Pull Request #97391 · rust-lang/rust

Urgau · 2022-05-25T11:14:14Z

This PR tries to handle more cases in the cfg_accessible implementation by only emitting a "not sure" error only if we have partially resolved a path.

This PR also adds many tests for the "not sure" cases and for private items.

I've addressed the review comments: removed known-bug and added the requested modification in rustc_resolve. I'm not fully sure about the last one and there are some diagnostics regression. But I want your opinion on it and it's ready for another review.

This is not a bug, if the compiler says "cannot determine" (rather than "not sure") then it's legitimately stuck, and it's unlikely we can do anything here.

The problem here is that we return an error instead of false (ie it is unresolvable).
The error message is irrelevant to the bug.

I've reverted the failed -> NonModule change as requested; I've posted the patch here https://gist.github.com/Urgau/7356282bc688ea3ab71b94412e86a2d1. I also responded to the last comment.
