Migrate rustc_monomorphize to use SessionDiagnostic by CleanCut · Pull Request #100730 · rust-lang/rust

CleanCut · 2022-08-18T21:56:16Z

Description

Migrates diagnostics in rustc_monomorphize to use SessionDiagnostic
Adds an impl IntoDiagnosticArg for PathBuf

TODO / Help!

I'm having trouble figuring out how to apply an optional note. 😕 Help!?
- Resolved. It was bad docs. Fixed in https://github.com/rust-lang/rustc-dev-guide/pull/1437/files
errors:RecursionLimit should be #[fatal ...], but that doesn't exist so it's #[error ...] at the moment.
- Maybe I can switch after this is merged in? --> Migrate rustc_ast_passes diagnostics to SessionDiagnostic and translatable messages (first part) #100694
- Or maybe I need to manually implement SessionDiagnostic instead of deriving it?
How does one go about converting an error inside of a call to struct_span_lint_hir?
~~What placeholder do you use in the fluent template to refer to the value in a vector? It seems like this code ought to have the answer (or something near it)...but I can't figure it out.~~ You can't. Punted.

I'm having trouble figuring out how to apply an optional note. 😕 Help!?

You can pute the #[note] attribute on a Option<()> field. It will be displayed only when the field is Some, like I did here :

@JeanCASPAR The problem turned out to be my relying on incorrectly-documented syntax! (It was on an Option<()> field already). It seems to work, now. Or at least, it's no longer in the list of lint errors. 😉

rustc_error_messages was changed

I've taken this PR out of draft status, because I'm now stuck and need a helpful reviewer to guide me forward. 😄

errors:RecursionLimit should be #[fatal ...], but that doesn't exist so it's #[error ...] at the moment.

Just skip this one for now and rebase after @finalchild's #100694 lands with #[fatal(..)] support.

How does one go about converting an error inside of a call to struct_span_lint_hir?

You can use emit_spanned_lint, just use the LintDiagnostic derive instead of SessionDiagnostic with #[lint(..)] instead of #[error(..)]. These don't need #[primary_span] attributes, which we don't currently prevent but I'm going to make a task about fixing now.

What placeholder do you use in the fluent template to refer to the value in a vector? It seems like this code ought to have the answer (or something near it)...but I can't figure it out.

We support Vec<Span> fields, if you want to have one message in a bunch of locations, but we otherwise don't have an amazing answer for how to write out lists of items in a translatable way. This is an open question, feel free to read about Fluent and try work out a nice way to do it, then we can follow your approach wherever else this comes up, but you can also just skip a diagnostic with this for now.

✅ CI Passing, ready for re-review
⚠️ I'm still experiencing a codegen failure locally on Apple Silicon.

I assume that the codegen failure is spurious because nothing you've changed should make a difference there - once you've rebased and fixed the conflicts, we can try merging this. Thanks for sticking with it :)

I hope so. The local codegen failure persists even after the rebase.

I think we're almost ready to land this - you've pushed a submodule update for Cargo though, which shouldn't be there.

✅ Fixed the errant submodule change. Ready for re-review.
