[WIP] Intra-doc links side of warning about undocumented items #82014

jyn514 · 2021-02-12T02:53:36Z

Unfortunately, this currently breaks because the cache is not populated
until later, so rustdoc thinks some items won't be documented when they
will be. Hoping to fix that separately, but opening this first so I don't forget about it.

Fixes #81979.

is will not be sounds fishy :)

Suggested change

diag.span_label(sp, "this item is will not be documented");

diag.span_label(sp, "this item is private and will not be documented");

"private" isn't correct, there are many reasons it might not be documented (e.g. it's a public export of a private item marked with no_inline; crate is masked; --extern-html-url wasn't passed).

jyn514 · 2021-02-17T00:19:02Z

FYI this is very broken currently and needs major refactors to rustdoc before merging, so I wouldn't bother looking at the typos and such just yet.

…eGomez Make `Clean` take &mut DocContext - Take `FnMut` in `rustc_trait_selection::find_auto_trait_generics` - Take `&mut DocContext` in most of `clean` - Collect the iterator in auto_trait_impls instead of iterating lazily; the lifetimes were really bad. This combined with rust-lang#82018 should hopefully help with rust-lang#82014 by allowing `cx.cache.exported_traits` to be modified in `register_res`. Previously it had to use interior mutability, which required either adding a RefCell to `cache.exported_traits` on *top* of the existing `RefCell<Cache>` or mixing reads and writes between `cx.exported_traits` and `cx.cache.exported_traits`. I don't currently have that working but I expect it to be reasonably easy to add after this.

…illaumeGomez Remove the dummy cache in `DocContext`; delete RenderInfo The same information is available everywhere; the only reason the dummy cache was needed is because it was previously stored in three different places. This consolidates the info a bit so the cache in `DocContext` is used throughout. As a bonus, it also completely removes `RenderInfo`. - Return a `Cache` from `run_global_ctxt`, not `RenderInfo` - Remove the unused `render_info` from `run_renderer` - Remove RenderInfo altogether Helps with rust-lang#82014. The next step is to move the `populate()` call before the `collect_intra_doc_links` pass, which currently breaks because a) lots of the cache is populated in early passes, and b) intra_doc_links itself sets some info with `register_res`. I'm working on separate PR for that to avoid making too many big changes at once. r? `@GuillaumeGomez`

camelid · 2021-03-12T04:14:13Z

I'm wondering if this might no longer be blocked given that #82018 has been merged?

jyn514 · 2021-03-12T21:45:38Z

@camelid this isn't blocked on anything in particular, I just need to figure out whether it's possible to make it work in the intra-doc pass itself or whether it has to be delayed until later when less diagnostic info is available (but more cache info is populated).

JohnCSimon · 2021-05-31T04:49:58Z

triage:
@jyn514 Can you post your status on this PR? Is it still WIP?

jyn514 · 2021-05-31T21:33:36Z

@JohnCSimon same status as in #82014 (comment). I don't know when I'll get a chance to work on it.

This comment is wrong - the actual issue is that primitive associated items are always reachable, but href doesn't take that into account
