I can't wait to finally get rid of at least some of the mess in our const-err-reporting-code. ;) r? `@oli-obk` Fixes rust-lang/rust#71800 Fixes rust-lang/rust#100114, Auto merge of rust-lang#2583 - RalfJung:rustup, r=oli-obk initial josh subtree sync This demonstrates what a josh-based rustup would look like with my patched josh. To create it I did ``` git fetch http://localhost:8000/rust-lang/rust.git:start=75dd959a3a40eb5b4574f8d2e23aa6efbeb33573[:prefix=src/tools/miri]:/src/tools/miri.git master git merge FETCH_HEAD ./rustup-toolchain HEAD && ./miri fmt git commit -am rustup ``` Unlike the [previous attempt](rust-lang/miri#2554), this does not add a new root commit to the repo. Once we merge this, we committed to using josh for subtree syncing, and in particular a version of josh that includes josh-project/josh#961 (or something compatible)., Stabilize half_open_range_patterns, Rollup merge of #102675 - ouz-a:mir-technical-debt, r=oli-obk Remove `mir::CastKind::Misc` As discussed in #97649 `mir::CastKind::Misc` is not clear, this PR addresses that by creating a new enum variant for every valid cast. r? ````@oli-obk````, [`unnecessary_cast`] Do not lint negative hexadecimal literals when cast as float Floats cannot be expressed as hexadecimal literals, ImplItemKind::TyAlias => ImplItemKind::Type, merge rustc history, Fix clippy tests that trigger `for_loop_over_fallibles` lint, fixup lint name, deprecate `clippy::for_loops_over_fallibles`, Rollup merge of #102829 - compiler-errors:rename-impl-item-kind, r=TaKO8Ki rename `ImplItemKind::TyAlias` to `ImplItemKind::Type` The naming of this variant seems inconsistent given that this is not really a "type alias", and the associated type variant for `TraitItemKind` is just called `Type`., Rollup merge of #102275 - Urgau:stabilize-half_open_range_patterns, r=cjgillot Stabilize `half_open_range_patterns` This PR stabilize `feature(half_open_range_patterns)`: ``` Allows using `..=X` as a pattern. ``` And adds a new `feature(half_open_range_patterns_in_slices)` for the slice part, rust-lang/rust#102275 (comment). The FCP was completed in rust-lang/rust#67264., Rename AssocItemKind::TyAlias to AssocItemKind::Type, Rollup merge of #99696 - WaffleLapkin:uplift, r=fee1-dead Uplift `clippy::for_loops_over_fallibles` lint into rustc This PR, as the title suggests, uplifts [`clippy::for_loops_over_fallibles`] lint into rustc. This lint warns for code like this: ```rust for _ in Some(1) {} for _ in Ok::<_, ()>(1) {} ``` i.e. directly iterating over `Option` and `Result` using `for` loop. There are a number of suggestions that this PR adds (on top of what clippy suggested): 1. If the argument (? is there a better name for that expression) of a `for` loop is a `.next()` call, then we can suggest removing it (or rather replacing with `.by_ref()` to allow iterator being used later) ```rust for _ in iter.next() {} // turns into for _ in iter.by_ref() {} ``` 2. (otherwise) We can suggest using `while let`, this is useful for non-iterator, iterator-like things like [async] channels ```rust for _ in rx.recv() {} // turns into while let Some(_) = rx.recv() {} ``` 3. If the argument type is `Result<impl IntoIterator, _>` and the body has a `Result<_, _>` type, we can suggest using `?` ```rust for _ in f() {} // turns into for _ in f()? {} ``` 4. To preserve the original behavior and clear intent, we can suggest using `if let` ```rust for _ in f() {} // turns into if let Some(_) = f() {} ``` (P.S. `Some` and `Ok` are interchangeable depending on the type) I still feel that the lint wording/look is somewhat off, so I'll be happy to hear suggestions (on how to improve suggestions :D)! Resolves #99272 [`clippy::for_loops_over_fallibles`]: https://rust-lang.github.io/rust-clippy/master/index.html#for_loops_over_fallibles, Rollup merge of #102868 - compiler-errors:rename-assoc-tyalias-to-ty, r=TaKO8Ki Rename `AssocItemKind::TyAlias` to `AssocItemKind::Type` Thanks `@camsteffen` for catching this in ast too, cc rust-lang/rust#102829 (comment), merge rustc history, Fix unclosed HTML tag in clippy doc, fix `box-default` ignoring trait objects' types, Fix allow_attributes_without_reason applying to external crate macros Previously the `clippy::allow_attributes_without_reason` lint would apply to external crate macros. Many macros in the Rust ecosystem include these `allow` attributes without adding a reason, making this lint pretty much unusable in any sizable Rust project.

(`internal_lints.rs` was over 1400 lines, which is a little unruly IMHO.) * ~Adds a new~ Expands the `unnecessary_def_path` internal lint to flag hardcoded paths to diagnostic and language items. My understanding is that the latter is currently done by reviewers. Automating this process should make things easier for both reviewers and contributors.
