This looks good in general, but I think there should be more tests, at least another set with tuple structs (e g. struct Toople(pub bool, usize);) and perhaps one test with a field named r#pub just because we can 😁.

I just had another look at the lint heuristic. It's not bad per se, but it might be improved further. I'm ok with merging as it is and doing a follow-up later, though. What do you think?

I'll add a similar lint partial_pub_variants for enums.

make const_err a hard error

This lint has been deny-by-default with future incompat wording since [Rust 1.51](rust-lang/rust#80394) and the stable release of this week starts showing it in cargo's future compat reports. I can't wait to finally get rid of at least some of the mess in our const-err-reporting-code. ;)

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).,

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).

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)!

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.

This commit fixes that by adding a check to the lint if the attribute is
from an external crate macro and returning early.,

changelog:[`default_numeric_fallback`] do not lint on constants,
Auto merge of rust-lang#9566 - smoelius:diagnostic-item-path, r=dswij

Expand internal lint `unnecessary_def_path`

This PR does essentially two things:
* Separates the internal lints into modules by pass. (`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.

I could make the first bullet a separate PR, or remove it entirely, if desired.
