rustdoc source view: `backtrace` 404s

[jsha]

Steps to reproduce:

1. Visit https://doc.rust-lang.org/std/
2. Click "source"
3. Open the sidebar
4. In the sidebar, click "backtrace", then "src", then "lib.rs".

Expected result: either backtrace's lib.rs loads, or it is not listed.

Actual result: 404 (https://doc.rust-lang.org/src/std/backtrace/src/lib.rs.html)

Hi,

I looked into this issue and found that the files listed in the sidebar is not actually present in the backtrace directory.

It only contain tests.rs (which i think is ignored).

I believe it's actually brought in as a submodule. See https://github.com/rust-lang/rust/tree/stable/library; and in a checked out rust repository, try ls library/backtrace/src/lib.rs.

Then I think it is some issue with submodule .

Testing locally, this was fixed by #106466. Rustdoc handled #[path = ../xx/yy.rs] modules inconsistently.

Now fixed on nightly - https://doc.rust-lang.org/nightly/src/std/backtrace/src/lib.rs.html

triage: fixed on stable too, and it seems like there's a regression test
