add doc_link_with_quotes lint
I'm not sure about wording, it seems OK to me but happy to change if other people have better ideas

changelog: add [`doc_link_with_quotes`] lint
Check `.fixed` paths' existence in `run_ui`
This PR adds a test to check that there exists a `.fixed` file for every `.stderr` file in `tests/ui` that mentions a `MachineApplicable` lint. The test leverages `compiletest-rs`'s `rustfix_coverage` option.
I tried to add `.fixed` files where they appeared to be missing. However, 38 exceptional `.rs` files remain. Several of those include comments indicating that they are exceptions, though not all do. Apologies, as I have not tried to associate the 38 files with GH issues. (I think that would be a lot of work, and I worry about linking the wrong issue.)

Fix `empty_line_after_outer_attribute` false positive
This PR fixes a false positive in `empty_line_after_outer_attribute`.
Here is a minimal example that trigger the FP:
```rust
#[derive(clap::Parser)]
#[clap(after_help = "This ia a help message.
You're welcome.
")]
pub struct Args;
```
changelog: PF: [`empty_line_after_outer_attribute`]: No longer lints empty lines in inner string values.
Introduce `allow-dbg-in-tests` config value
related to: Issue #8758, PR https://github.com/rust-lang/rust-clippy/pull/8838
changelog: Introduced `allow-dbg-in-tests` config value. [dbg_macro] does not allow `dbg!` in test code by default.
`get_last_with_len`: lint `VecDeque` and any deref to slice
changelog: [`get_last_with_len`]: lint `VecDeque` and any deref to slice
Previously only `Vec`s were linted, this will now catch any usages on slices, arrays, etc. It also suggests `.back()` for `VecDeque`s
Also moves the lint into `methods/`
Add some testcases for recent rustfix update
changelog: none
This adds a testcase for a bugfix that has been fixed by https://github.com/rust-lang/rustfix/tree/v0.6.1
`rustfix` is pulled in by `compiletest_rs`. So to test that the correct rustfix version is used, I added one (and a half) testcase.
I tried to add a testcase for #8734 as well, but interesting enough the rustfix is wrong:
```diff
fn issue8734() {
let _ = [0u8, 1, 2, 3]
.into_iter()
- .and_then(|n| match n {
+ .flat_map(|n| match n {
+ 1 => [n
+ .saturating_add(1)
1 => [n
.saturating_add(1)
.saturating_add(1)
.saturating_add(1)
.saturating_add(1)
.saturating_add(1)
.saturating_add(1)
.saturating_add(1)
.saturating_add(1)],
n => [n],
});
}
```
this needs some investigation and then this testcase needs to be enabled by commenting it out

`identity_op`: add parenthesis to suggestions where required
changelog: [`identity_op`]: add parenthesis to suggestions where required
Follow up to #8730, wraps the cases we can't lint as-is in parenthesis rather than ignoring them
Catches a couple new FPs with mixed operator precedences and `as` casts
```rust
// such as
0 + { a } * 2;
0 + a as usize;
```
The suggestions are now applied using `span_lint_and_sugg` rather than appearing in just the message and have a `run-rustfix` test
[dbg_macro] tolerates use of `dbg!` in items which have `#[cfg(test)]` attribute
fix: #8758
changelog: [dbg_macro] tolerates use of `dbg!` in items with `#[cfg(test)]` attribute
add suggestions to rc_clone_in_vec_init
A followup to https://github.com/rust-lang/rust-clippy/pull/8769
I also switch the order of the 2 suggestions, since the loop initialization one is probably the common case.
`@xFrednet` I'm not letting you guys rest for a minute 😅
changelog: add suggestions to [`rc_clone_in_vec_init`]
`undocumented_unsafe_blocks` does not trigger on unsafe trait impls
Closes#8505
changelog: This lint checks unsafe impls NOT from macro expansions and checks ones in macro declarations.
~~`unsafe impl`s from macro invocations don't trigger the lint for now.~~
~~This lint checks unsafe impls from/not from macro expansions~~
Don't lint `vec_init_then_push` when further extended
fixes#7071
This will still lint when a larger number of pushes are done (four currently). The exact number could be debated, but this is more readable then a sequence of pushes so it shouldn't be too large.
changelog: Don't lint `vec_init_then_push` when further extended.
changelog: Remove `mut` binding from `vec_init_then_push` when possible.
Fix redundant_allocation warning for Rc<Box<str>>
changelog: [`redundant_allocation`] Fixes#8604
Fixes false positives where a fat pointer with `str` type was made thin by another allocation, but that thinning allocation was marked as redundant
