Tracking issue for Path Prefix Remapping #41555
Good question. I did not heard any complaints about the way things currently work -- which I interpret as everybody being happy
Other than that, two open topics are:
I personally would be fine with either of the first two options.
We use it in clippy for making our tests' stderr output OS independent. Works like a charm: https://github.com/Manishearth/rust-clippy/blob/master/tests/examples.rs#L29
Oh right. I was going by the code at the bottom of this older comment, I didn't notice you had gone back to plain string matching. What was the reason? I know GCC also do plain string matching, but I actually prefer path-level matching because it would be easier to use. This cross-platform duplication issue is a further example in that area.
@infinity0 I'm divided on whether path matching should be string- or component-based. Component-based is a bit more ergonomic in the cross-platform case. I'm not sure though if it can be somewhat less predictable in corner cases (e.g. strange Windows path prefixes).
@jsgf That should be doable.
I'm nominating this for the next @rust-lang/dev-tools meeting to discuss string matching and which form the CLI should take -- and then we can let the appropriate subteams vote on it.
@rust-lang/core: Which teams need to sign off on stabilizing this? Quick recap: This feature allows to remap file paths (in output messages and output artifacts) to be remapped. This is necessary for reproducible builds and helps with custom debugging setups.

I can confirm that #44940 fixed the compile issues I was seeing when using this feature and a simple
Thoughts on privacy
I think this feature possesses the mechanics to more broadly address privacy issues for closed-source code. This may be out of scope for the current issue, but I wanted to bring it up now since this feature hasn't been fully implemented yet.
The current reality for closed source code is that any time a
