From 50c659fcba19f6d51d465815cadcea00d8abb02b Mon Sep 17 00:00:00 2001 From: Marijn Schouten Date: Fri, 14 Mar 2025 17:30:47 +0100 Subject: [PATCH 01/21] Clarify "owned data" in E0515.md This clarifies the explanation of why this is not allowed and also what to do instead. Fixes 62071 PS There was suggestion of adding a link to the book. I did not yet do that, but if desired that could be added. --- compiler/rustc_error_codes/src/error_codes/E0515.md | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/compiler/rustc_error_codes/src/error_codes/E0515.md b/compiler/rustc_error_codes/src/error_codes/E0515.md index 0f4fbf672239c..87bbe4aea705f 100644 --- a/compiler/rustc_error_codes/src/error_codes/E0515.md +++ b/compiler/rustc_error_codes/src/error_codes/E0515.md @@ -17,10 +17,13 @@ fn get_dangling_iterator<'a>() -> Iter<'a, i32> { } ``` -Local variables, function parameters and temporaries are all dropped before the -end of the function body.

From 6698c26b3ab9ef90a31af1afc367bab3a359563c Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Wed, 12 Mar 2025 13:45:48 +1100 Subject: [PATCH 16/21] Fix `is_relevant_impl`. It determines if a function should have any `inline` attributes checked. For `ItemKind::Fn` it returns true or false depending on the details of the function; for anything other item kind it returns *true*. This latter case should instead be *false*. (In the nearby and similar functions `is_relevant_impl` and `is_relevant_trait` the non-function cases return false.) The effect of this is that non-functions are no longer checked. But rustc already disallows `inline` on any non-function items. So if anything its a tiny performance win, because that was useless anyway. --- src/tools/clippy/clippy_lints/src/attrs/utils.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/tools/clippy/clippy_lints/src/attrs/utils.rs b/src/tools/clippy/clippy_lints/src/attrs/utils.rs index 0e650e4939252..a5ce2137bffeb 100644 --- a/src/tools/clippy/clippy_lints/src/attrs/utils.rs +++ b/src/tools/clippy/clippy_lints/src/attrs/utils.rs @@ -24,7 +24,7 @@ pub(super) fn is_relevant_item(cx: &LateContext<'_>, item: &Item<'_>) -> bool { if let ItemKind::Fn { body: eid, .. } = item.kind { is_relevant_expr(cx, cx.tcx.typeck_body(eid), cx.tcx.hir_body(eid).value) } else { - true + false } } From b14810669a805003cf6392447c08eed79441936f Mon Sep 17 00:00:00 2001 From: Charalampos Mitrodimas Date: Sun, 16 Mar 2025 11:28:21 +0100 Subject: [PATCH 17/21] Fix ICE: attempted to remap an already remapped filename This commit fixes an internal compiler error (ICE) that occurs when rustdoc attempts to process macros with a remapped filename. The issue arose during macro expansion when the `--remap-path-prefix` option was used. Instead of passing remapped filenames through, which would trigger the "attempted to remap an already remapped filename" panic, we now extract the original local path from remapped filenames before processing them. A test case has been added to verify this behavior.

All of this is quite non-obvious; the only documentation is a single comment saying "The name might be a dummy name in case of anonymous items". Some sites that handle items check for an empty ident, some don't. This is a very C-like way of doing things, but this is Rust, we have sum types, we can do this properly and never forget to check for the exceptional case and never YOLO possibly empty identifiers (or possibly dummy spans) around and hope that things will work out. The commit is large but it's mostly obvious plumbing work. Some notable things. - A similar transformation makes sense for `ast::Item`, but this is already a big change. That can be done later. - Lots of assertions are added to item lowering to ensure that identifiers are empty/non-empty as expected. These will be removable when `ast::Item` is done later. - `ItemKind::Use` doesn't get an `Ident`, but `UseKind::Single` does. - `lower_use_tree` is significantly simpler. No more confusing `&mut Ident` to deal with. - `ItemKind::ident` is a new method, it returns an `Option`. It's used with `unwrap` in a few places; sometimes it's hard to tell exactly which item kinds might occur. None of these unwraps fail on the test suite. It's conceivable that some might fail on alternative input. We can deal with those if/when they happen. - In `trait_path` the `find_map`/`if let` is replaced with a loop, and things end up much clearer that way. - `named_span` no longer checks for an empty name; instead the call site now checks for a missing identifier if necessary. - `maybe_inline_local` doesn't need the `glob` argument, it can be computed in-function from the `renamed` argument. - `arbitrary_source_item_ordering::check_mod` had a big `if` statement that was just getting the ident from the item kinds that had one. It could be mostly replaced by a single call to the new `ItemKind::ident` method. - `ItemKind` grows from 56 to 64 bytes, but `Item` stays the same size, and that's what matters, because `ItemKind` only occurs within `Item`. --- compiler/rustc_ast_lowering/src/index.rs | 2 +- compiler/rustc_ast_lowering/src/item.rs | 114 +++++++++----- .../src/diagnostics/mutability_errors.rs | 8 +- compiler/rustc_hir/src/hir.rs | 148 +++++++++++------- compiler/rustc_hir/src/intravisit.rs | 45 ++++-- .../rustc_hir_analysis/src/check/wfcheck.rs | 24 +-- compiler/rustc_hir_analysis/src/collect.rs | 34 ++-- .../rustc_hir_analysis/src/collect/dump.rs | 2 +- .../src/collect/predicates_of.rs | 7 +- .../src/collect/resolve_bound_vars.rs | 16 +- .../rustc_hir_analysis/src/collect/type_of.rs | 12 +- .../src/hir_ty_lowering/lint.rs | 7 +- .../rustc_hir_analysis/src/hir_wf_check.rs | 6 +- compiler/rustc_hir_pretty/src/lib.rs | 63 ++++---- compiler/rustc_hir_typeck/src/callee.rs | 4 +- compiler/rustc_hir_typeck/src/demand.rs | 5 +- .../src/fn_ctxt/suggestions.rs | 3 +- .../src/method/prelude_edition_lints.rs | 23 +-- .../rustc_hir_typeck/src/method/suggest.rs | 10 +- compiler/rustc_hir_typeck/src/pat.rs | 2 +- compiler/rustc_lint/src/builtin.rs | 18 +-- .../src/default_could_be_derived.rs | 6 +- compiler/rustc_lint/src/internal.rs | 6 +- .../src/multiple_supertrait_upcastable.rs | 4 +- compiler/rustc_lint/src/non_local_def.rs | 6 +- compiler/rustc_lint/src/nonstandard_style.rs | 14 +- compiler/rustc_lint/src/types.rs | 10 +- compiler/rustc_metadata/src/rmeta/encoder.rs | 2 +- compiler/rustc_middle/src/hir/map.rs | 36 +++-- compiler/rustc_middle/src/ty/print/pretty.rs | 8 +- compiler/rustc_mir_build/src/builder/mod.rs | 2 +- .../src/thir/pattern/check_match.rs | 6 +- compiler/rustc_passes/src/check_attr.rs | 16 +- compiler/rustc_passes/src/dead.rs | 8 +- compiler/rustc_passes/src/reachable.rs | 4 +- compiler/rustc_passes/src/stability.rs | 6 +- compiler/rustc_privacy/src/lib.rs | 23 +-- .../src/error_reporting/infer/mod.rs | 2 +- .../src/error_reporting/traits/ambiguity.rs | 9 +- .../src/error_reporting/traits/mod.rs | 7 +- .../src/error_reporting/traits/suggestions.rs | 50 +++--- compiler/rustc_trait_selection/src/errors.rs | 2 +- src/librustdoc/clean/mod.rs | 35 +++-- src/librustdoc/clean/types.rs | 4 +- src/librustdoc/doctest/rust.rs | 50 ++++-- src/librustdoc/html/render/span_map.rs | 29 ++-- .../passes/calculate_doc_coverage.rs | 2 +- src/librustdoc/visit_ast.rs | 41 +++-- .../src/arbitrary_source_item_ordering.rs | 86 ++++------ .../clippy/clippy_lints/src/attrs/mod.rs | 6 +- .../clippy_lints/src/disallowed_types.rs | 2 +- .../clippy/clippy_lints/src/enum_clike.rs | 2 +- .../clippy_lints/src/error_impl_error.rs | 6 +- src/tools/clippy/clippy_lints/src/escape.rs | 2 +- .../clippy_lints/src/excessive_bools.rs | 2 +- .../clippy_lints/src/exhaustive_items.rs | 2 +- .../clippy_lints/src/functions/result.rs | 2 +- .../clippy_lints/src/item_name_repetitions.rs | 38 +++-- .../src/items_after_test_module.rs | 14 +- .../clippy_lints/src/large_const_arrays.rs | 4 +- .../clippy_lints/src/large_enum_variant.rs | 4 +- .../src/legacy_numeric_constants.rs | 4 +- src/tools/clippy/clippy_lints/src/len_zero.rs | 18 +-- .../clippy_lints/src/manual_non_exhaustive.rs | 4 +- .../clippy/clippy_lints/src/missing_doc.rs | 8 +- .../src/missing_enforced_import_rename.rs | 2 +- .../src/missing_fields_in_debug.rs | 2 +- .../clippy/clippy_lints/src/missing_inline.rs | 2 +- .../src/no_mangle_with_rust_abi.rs | 4 +- .../clippy_lints/src/non_std_lazy_statics.rs | 2 +- .../clippy_lints/src/pub_underscore_fields.rs | 2 +- .../clippy_lints/src/redundant_pub_crate.rs | 6 +- .../src/self_named_constructors.rs | 3 +- .../clippy_lints/src/trailing_empty_array.rs | 2 +- .../clippy/clippy_lints/src/trait_bounds.rs | 4 +- .../clippy/clippy_lints/src/types/mod.rs | 2 +- .../src/undocumented_unsafe_blocks.rs | 4 +- .../src/unnecessary_box_returns.rs | 4 +- .../clippy_lints/src/unused_trait_names.rs | 6 +- .../clippy_lints/src/upper_case_acronyms.rs | 8 +- .../clippy_utils/src/check_proc_macro.rs | 4 +- src/tools/clippy/clippy_utils/src/lib.rs | 21 +-- 82 files changed, 667 insertions(+), 556 deletions(-) diff --git a/compiler/rustc_ast_lowering/src/index.rs b/compiler/rustc_ast_lowering/src/index.rs index d1e23bf252229..26c0e7e5f82af 100644 --- a/compiler/rustc_ast_lowering/src/index.rs +++ b/compiler/rustc_ast_lowering/src/index.rs @@ -164,7 +164,7 @@ impl<'a, 'hir> Visitor<'hir> for NodeCollector<'a, 'hir> { fn visit_item(&mut self, i: &'hir Item<'hir>) { debug_assert_eq!(i.owner_id, self.owner);
