Update changelog for 1.52 I've underestimated the work that goes into this a bit, but it just shows that a lot has happened again in Clippy in 1.52 🙃. [Rendered](https://github.com/xFrednet/rust-clippy/blob/changelog-1-52/CHANGELOG.md) --- changelog: none
Fix bad suggestion when a reborrow might be required Fix bad suggestion when the value being sliced is a macro call Don't lint inside of a macro due to the previous context sensitive changes
Improve `redundant_slicing` fixes: rust-lang#6968 changelog: Fix `redundant_slicing` suggestion when a reborrow might be required or when the value is from a macro call
Add MSRV options to `unnested_or_patterns` changelog: [`unnested_or_patterns`] can now be configured with the `msrv` config/attribute. Fixes rust-lang#6953
When the character next to `{}` is "shifted" (when mapping a byte index
in the format string to span) we should avoid shifting the span end
index, so first map the index of `}` to span, then bump the span,
instead of first mapping the next byte index to a span (which causes
bumping the end span too much).
Regression test added.
Fixes rust-lang#83344
Check the return type of `len`. Only integral types, or an `Option` or `Result` wrapping one. Ensure the return type of `is_empty` matches. e.g. `Option<usize>` -> `Option<bool>`
`len_without_is_empty` improvements fixes: rust-lang#6958 fixes: rust-lang#6972 changelog: Check the return type of `len`. Only integral types, or an `Option` or `Result` wrapping one. changelog: Ensure the return type of `is_empty` matches. e.g. `Option<usize>` -> `Option<bool>`
Add missing lints to MSRV config doc r? `@giraffate` changelog: Add missing lints to MSRV config doc
Add function core::iter::zip
This makes it a little easier to `zip` iterators:
```rust
for (x, y) in zip(xs, ys) {}
// vs.
for (x, y) in xs.into_iter().zip(ys) {}
```
You can `zip(&mut xs, &ys)` for the conventional `iter_mut()` and
`iter()`, respectively. This can also support arbitrary nesting, where
it's easier to see the item layout than with arbitrary `zip` chains:
```rust
for ((x, y), z) in zip(zip(xs, ys), zs) {}
for (x, (y, z)) in zip(xs, zip(ys, zs)) {}
// vs.
for ((x, y), z) in xs.into_iter().zip(ys).zip(xz) {}
for (x, (y, z)) in xs.into_iter().zip((ys.into_iter().zip(xz)) {}
```
It may also format more nicely, especially when the first iterator is a
longer chain of methods -- for example:
```rust
iter::zip(
trait_ref.substs.types().skip(1),
impl_trait_ref.substs.types().skip(1),
)
// vs.
trait_ref
.substs
.types()
.skip(1)
.zip(impl_trait_ref.substs.types().skip(1))
```
This replaces the tuple-pair `IntoIterator` in rust-lang#78204.
There is prior art for the utility of this in [`itertools::zip`].

look inside refs and detect if let &None = ... Fixes rust-lang/rust-clippy#5396 changelog: redundant_pattern_matching: look inside Refs to fix FNs with "if let &None = .. "

New Lint: `branches_sharing_code`
This lint checks if all `if`-blocks contain some statements that are the same and can be moved out of the blocks to prevent code duplication. Here is an example:
```rust
let _ = if ... {
println!("Start"); // <-- Lint for code duplication
let _a = 99;
println!("End"); // <-- Lint for code duplication
false
} else {
println!("Start");
let _b = 17;
println!("End");
false
};
```
This could be written as:
```rust
println!("Start");
let _ = if ... {
let _a = 99;
false
} else {
let _b = 17;
false
};
println!("End");
```
---
This lint will get masked by the `IF_SAME_THEN_ELSE` lint. I think it makes more sense to only emit one lint per if block. This means that the folloing example:
```rust
if ... {
let _a = 17;
} else {
let _a = 17;
}
```
Will only trigger the `IF_SAME_THEN_ELSE` lint and not the `SHARED_CODE_IN_IF_BLOCKS` lint.

And hello to the one that is writing the changelog for this release :D
fix `missing_panics_doc` not detecting `assert_eq!` and `assert_ne!` fixes rust-lang#6997 changelog: `missing_panics_doc` detects `assert_eq!` and `assert_ne!` --- searching for `assert_eq!` and `assert_ne!` in `FindPanicUnwrap`
Don't trigger `same_item_push` if the vec is used in the loop body fixes rust-lang#6987 changelog: `same_item_push`: Don't trigger if the `vec` is used in the loop body
consider mutability on useless_vec suggestions fixes rust-lang#7035 changelog: Now the suggested by `useless_vec` considers mutability to suggest either `&[]`, as before, or `&mut []` if the used reference is mutable.
…1995 Fix all occurences `needless_borrow` internally The bug that got 'needless_borrow' moved into the nursery was fixed two years ago in d4370f8. This did trigger over a thousand times internally, so that's all the other changes. I vetted most of them, but there's a lot The only interesting change is to the lint list. `declare_tool_lint` already makes a reference, so there's no need to take a reference to the lints. changelog: None
Remove some dead utils changelog: none
Soft deprecate match_path and match_qpath changelog: none From zulip [disucssion](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/match_.5Bq.5Dpath.20is.20bad.3F).
Some symbol optimizations changelog: none
Use AnonConst for asm! constants This replaces the old system which used explicit promotion. See rust-lang#83169 for more background. The syntax for `const` operands is still the same as before: `const <expr>`. Fixes rust-lang#83169 Because the implementation is heavily based on inline consts, we suffer from the same issues: - We lose the ability to use expressions derived from generics. See the deleted tests in `src/test/ui/asm/const.rs`. - We are hitting the same ICEs as inline consts, for example rust-lang#78174. It is unlikely that we will be able to stabilize this before inline consts are stabilized.
