Tracking issue for the unreachable_pub compatibility lint

[Manishearth]

In Rust 2018, we will deprecate code that is pub but not crate-reachable, requiring pub(crate) instead.

If you see this warning, just replace the relevant line with pub(crate)

Does this just mean that the unreachable-pub lint will become default-Warn (it's currently default-Allow), or is something stronger intended?

Is stabilization of the crate visibility modifier (synonymous to pub(crate)) potentially relevant here? (The lint will already suggest crate or pub(crate) depending on the crate_visibility_modifier feature flag, but if "non-crate-reachable code isn't pub" is something to teach/sell as part of "Rust 2018", maybe the new keyword use is, too.)

There is one outstanding bug report for the lint: #47816

[Manishearth]

I'm not sure. I think it will be allow for now but may become warn later, regardless of the epoch you're on. @withoutboats may know.

I filed this issue so the lint can be marked an epoch-related lint (you need a tracking issue), there's not much more to infer from that.

I think it will be allow for now but may become warn later, regardless of the epoch you're on. @withoutboats may know.

We're not sure.

This lint isn't actually a future compat lint, closing the tracking issue.
