2025-07-13Adjust `run_make_support::symbols` helpersJieyou Xu-25/+264
Massage the `symbols` helpers to fill out {match all, match any} x {substring match, exact match}: | | Substring match | Exact match | |-----------|----------------------------------------|-------------------------------| | Match any | `object_contains_any_symbol_substring` | `object_contains_any_symbol` | | Match all | `object_contains_all_symbol_substring` | `object_contains_all_symbols` | As part of this, rename `any_symbol_contains` to `object_contains_any_symbol_substring` for accuracy.
2025-07-13Auto merge of #140717 - mejrs:diagnostic_lints, r=oli-obkbors-59/+157
Split up the `unknown_or_malformed_diagnostic_attributes` lint This splits up the lint into the following lint group: - `unknown_diagnostic_attributes` - triggers if the attribute is unknown to the current compiler - `misplaced_diagnostic_attributes` - triggers if the attribute exists but it is not placed on the item kind it's meant for - `malformed_diagnostic_attributes` - triggers if the attribute's syntax or options are invalid - `malformed_diagnostic_format_literals` - triggers if the format string literal is invalid, for example if it has unpaired curly braces or invalid parameters - this pr doesn't create it, but future lints for things like deprecations can also go here. This PR does not start emitting lints in places that previously did not. ## Motivation I want to have finer control over what `unknown_or_malformed_diagnostic_attributes` does I have a project with fairly low msrv that is/will have a lower msrv than future diagnostic attributes. So lints will be emitted when I or others compile it on a lower msrv. At this time, there are two options to silence these lints: - `#[allow(unknown_or_malformed_diagnostic_attributes)]` - this risks diagnostic regressions if I (or others) mess up using the attribute, or if the attribute's syntax ever changes. - write a build script to detect the compiler version and emit cfgs, and then conditionally enable the attribute: ```rust #[cfg_attr(rust_version_99, diagnostic::new_attr_in_rust_99(thing = ..))]` struct Foo; ``` or conditionally `allow` the lint: ```rust // lib.rs #![cfg_attr(not(current_rust), allow(unknown_or_malformed_diagnostic_attributes))] ``` I like to avoid using build scripts if I can, so the following works much better for me. That is what this PR will let me do in the future: ```rust #[allow(unknown_diagnostic_attribute, reason = "attribute came out in rust 1.99 but msrv is 1.70")] #[diagnostic::new_attr_in_rust_99(thing = ..)]` struct Foo;

fix: Include frontmatter in -Zunpretty output In the implementation (rust-lang/rust#140035), this was left as an open question for the tracking issue (rust-lang/rust#136889). My assumption is that this should be carried over. The test was carried over from rust-lang/rust#137193 which was superseded by rust-lang/rust#140035. Thankfully, either way, `-Zunpretty` is unstable and we can always change it even if we stabilize frontmatter.
2025-07-11Rollup merge of #143661 - Muscraft:other-suggestion-message, r=estebankMatthias Krüger-14/+301
chore: Improve how the other suggestions message gets rendered Note: This change is part of my ongoing work to use `annotate-snippets` as `rustc`'s emitter This change started as a way to remove some specialty code paths from `annotate-snippets`, by making the "and {} other candidates" message get rendered like a secondary message with no level, but turned into a fix for the message's Unicode output. Before this change, when using the Unicode output, the other suggestions message would get rendered outside of the main suggestion block, making it feel disconnected from what it was referring to. This change makes it so that the message is on the last line of the block, aligning its rendering with other secondary messages, and making it clear what the message is referring to. Before: ``` error[E0433]: failed to resolve: use of undeclared type `IntoIter` ╭▸ $DIR/issue-82956.rs:28:24 │ LL │ let mut iter = IntoIter::new(self); │ ━━━━━━━━ use of undeclared type `IntoIter` ╰╴ help: consider importing one of these structs ╭╴ LL + use std::array::IntoIter; ├╴ LL + use std::collections::binary_heap::IntoIter; ├╴ LL + use std::collections::btree_map::IntoIter; ├╴ LL + use std::collections::btree_set::IntoIter; ╰╴ and 9 other candidates ``` After: ``` error[E0433]: failed to resolve: use of undeclared type `IntoIter` ╭▸ $DIR/issue-82956.rs:28:24 │ LL │ let mut iter = IntoIter::new(self); │ ━━━━━━━━ use of undeclared type `IntoIter` ╰╴ help: consider importing one of these structs ╭╴ LL + use std::array::IntoIter; ├╴ LL + use std::collections::binary_heap::IntoIter; ├╴ LL + use std::collections::btree_map::IntoIter; ├╴ LL + use std::collections::btree_set::IntoIter; │ ╰ and 9 other candidates ```

Rework borrowing suggestions to use `Expr` instead of just `Span` In the suggestion machinery for borrowing expressions and types, always use the available obligation `Span` to find the appropriate `Expr` to perform appropriateness checks no the `ExprKind` instead of on the textual snippet corresponding to the `Span`. (We were already doing this, but only for a subset of cases.) This now better handles situations where parentheses and `<>` are needed for correct syntax (`&(foo + bar)`, `(&foo).bar()`, `<&Foo>::bar()`, etc.). Unify the logic for the case where `&` *and* `&mut` are appropriate with the logic for only one of those cases. (Instead of having two branches for emitting the suggestion, we now have a single one, using `Diag::multipart_suggestions` always.) Handle the case when `S::foo()` should have been `<&S>::foo()` (instead of suggesting the prior `&S::foo()`. Fix rust-lang/rust#143393. Make `Diag::multipart_suggestions` always verbose. CC rust-lang/rust#141973.

Fix `--skip-std-check-if-no-download-rustc` Since https://github.com/rust-lang/rust/pull/143048, we now explicitly set the build compiler for `check::Std`, which caused it to be built before we checked `--skip-std-check-if-no-download-rustc`. So I moved the check earlier to `make_run`, which resolves it. I also added a regression test for this. Sadly we can't really test for the positive case easily (when download-ci-rustc is enabled), but we can test the negative cases, where it is disabled.
