Fixes https://github.com/rust-lang/rust-clippy/issues/10780
We correctly no longer give a warning when a closure is passed to a
method, where one of the arguments to that method uses the variable
which would be shadowed by an argument to that closure.
Uses is defined loosely as any expression used in the calling expression
mentions the shadowee binding (except for the closure itself):
```rust
#![deny(clippy::shadow_unrelated)]
let x = Some(1);
let y = x.map(|x| x + 1);
```
will now succeed.
See https://github.com/linebender/xilem/pull/745 - without this change,
all of the `expect(shadow_unrelated)` in the repository are met; with
it, none of them are.
changelog: [`shadow_unrelated`]: Don't treat closures arguments as
unrelated when the calling function uses them
changelog: [`trait_duplication_in_bounds`]: trigger on duplicate const
associated constraint as well
~~The first commit is part of #13722 which must be merged first.~~
This should address #13099 for the `derivable_impls` test. As I've not
contributed to clippy before, I'd like to make sure i'm on the right
track before doing more :)

feedback
It's becoming more and more common to see people including markdown
files in their code using `doc = include_str!("...")`, which is great.
However, often there is no condition on this include, which is not great
because it slows down compilation and might trigger recompilation if
these files are updated.
This lint aims at fixing this situation.
changelog: Add new lint `doc_include_without_cfg`
On arm64 I get
```
error[E0570]: `"vectorcall"` is not a supported ABI for the current target
```
We don't seem to be doing any ABI specific handling so it seems fine to
just remove this one since there are other tests

Two changes to `redundant_guards`:
- Lint float literals. We used to do that before but that was changed in
#11305 because at the time there was a future compat warning and it was
planned to make pattern matching floats a hard error.
In rust-lang/rust#116284 it was decided to actually remove the lint and
only make matching `NAN` specifically a hard error. The `NAN` part isn't
relevant/important here because this PR only changes what literals are
warned and `f64::NAN` isn't a literal, but I've added a test anyway to
make sure we continue to not lint there.
- Don't lint CStr literals because that can't be a pattern right now
(fixes#13681)
changelog: none
Add support for `#[clippy::format_args]` attribute that can be attached to any macro to indicate that it functions the same as the built-in format macros like `format!`, `println!` and `write!`
In preparation of #13556, I want to remove the dependency on
`clippy_config`, as I don't think that we want to publish that for
outside consumers. To do this the 2 dependecies on `clippy_config` had
to be removed:
1. The MSRV implementation was in `clippy_config`, but was required in
`qualify_min_const`. I think exposing the MSRV infrastructure and the
MSRVs we defined might also be helpful for `clippy_utils` users. I don't
see why it should not be able to live in `clippy_utils` from a technical
point of few.
2. The `create_disallowed_map` function that took in a
`clippy_utils::types::DisallowedPath` is moved to the `DisallowedPath`
implementation. This also fits there and is only useful for Clippy and
not in `clippy_utils` for external consumers.
`clippy_config` now depends in `clippy_utils`, so the dependecy just got
reversed. But having the `clippy_utils` crate as the base of the
dependency tree in Clippy makes sense.

Closes#6947
This changes the lint to allow futures which are not `Send` as a result
of a generic type parameter not having a `Send` bound and only lint
futures that are always `!Send` for any type, which I believe is the
more useful behavior (like the comments in the linked issue explain).
This is still only a heuristic (I'm not sure if there's a more general
way to do this), but it should cover the common cases I could think of
(including the code examples in the linked issue)

Fixes#13670.
Bug was that I forgot to add the comparison with the included file
content length...
changelog: Fix `large_include_file` lint being triggered all the time by
doc comments
The `identity_op` lint was suggesting code fixes that resulted in
incorrect or broken code, due to missing parenthesis in the fix that
changed the semantics of the code.
For a binary expression, `left op right`, if the `left` was redundant,
it would check if the right side needed parenthesis, but if the `right`
was redundant, it would just assume that the left side did not need
parenthesis.
This can result in rustfix generating broken code and failing, or
generating code that has different behavior than before the fix. e.g.
`-(x + y + 0)` would turn into `-x + y`, changing the behavior, and
`1u64 + (x + y + 0i32) as u64` where `x: i32` and `y: i32` would turn
into `1u64 + x + y as u64`, creating an error where `x` cannot be added
to the other values, as it was never cast to `u64`.
This commit fixes both of these problems by always checking the
non-redundant child of a binary expression for needed parenthesis.

changed behavior
The author lint is not an internal lint, and should also be enabled, when Clippy
is distributed through rustup. This moves the author lint test cases back to
tests/ui.

no_mangle attribute requires unsafe in Rust 2024
Tests without unsafe must not run in edition 2024. Also, error messages have been modified to include the full attribute, so that a use of `#[unsafe(no_mangle)]` does not produce an error message containing `#[no_mangle]`.
changelog: [`no_mangle_attribute`]: handle `#[unsafe(no_mangle)]` as well
