Ignore rustc_private items from std docs #76571

tesuji · 2020-09-10T13:23:05Z

By ignoring rustc_private items for non local impl block,
this may fix #74672 and fix #75588 .

This might suppress #76529 if it is simple enough for backport.

Thanks so much for working on this! Just a few nits.

+        //
+        // NOTE: This cannot be added to `LINKCHECK_EXCEPTIONS` because the resolved path

+        // So the `strip_prefix` method just returns the old absolute broken path.


Yeah, this comment seems fine. nit: this could be else if so you don't need the early return, but won't block on that

I removed all the added doc to make this patch smaller to be able to backport.

Oh, I don't think there's need for that, the comments won't hurt anything. It's logic changes I'm worried about backporting.

@bors r+

on getting this into nightly. Now about getting this into beta: @rust-lang/rustdoc I see three options:

Don't backport anything. Beta/stable will be missing Join and other unstable traits (Missing Implementors for Join and Pattern trait in rustdoc #75588), and have some rustc_private traits (impl Deref for EndianSlice appears in std docs #74672). This is IMO the worst outcome.
Backport Particially revert #73771 #76529 which is a simple revert. Beta/stable will have Join, but also have other documentation about rustc_private items like gimli traits. This is the most conservative option: it exposes rustc internals, but it makes sure there's no missing docs.
Backport this PR. Beta/stable will have Join and will not have rustc_private items, but there's the possibility this introduces a bug by accident.

Personally I'm in favor of 3, but I'm willing to be convinced by 2. What do you think?

@lzutao please don't force push, github now shows a 4k line diff before and after.

Yeah, I'm sorry. But GitHub could improve their compare page.
At local you could run git range-diff c3d048a...c743fc4, it is a lot cleaner.
My local result of that command:

@@ src/tools/linkchecker/main.rs: fn is_exception(file: &Path, link: &str) -> bool
 +        // calculated in `check` function is outside `build/<triple>/doc` dir.
 +        // So the `strip_prefix` method just returns the old absolute broken path.
 +        if file.ends_with("std/primitive.slice.html") {
-+            if link.ends_with("std/primitive.slice.html") {
++            if link.ends_with("primitive.slice.html") {
 +                return true;
 +            }
 +        }

What change did you make to fix the tidy error?

I simply removed the "std/" prefix, cause windows path (in this case has type lossy &str) usually has \ as path separators.

Yeah, I've suggested this before (isaacs/github#1834) but it was ignored.

Ok, the change looks fine.

Yeah, that's sad. But I think running range-diff still requires more calculation power than just normal diff.
Consider that github processes thousands of diff requests per second (I guess), it could be a burden for their servers.
Still they could have reply that instead of ignoring the issue.

@lzutao to backport this to beta, make a PR with the same commits, but against the beta branch instead of master: https://forge.rust-lang.org/release/beta-backporting.html
Then the rustdoc team will decided whether or not it should be backported.

jyn514 · 2020-09-14T12:48:50Z

@rust-lang/rustdoc this is waiting on a decision about backporting: #76571 (comment)

GuillaumeGomez · 2020-09-14T12:52:15Z

Is there any reason why we shouldn't? If not I guess it's fine to approve the backport.
