48d54942f5 Auto merge of #8504 - xFrednet:8502-allow-lint-without-reason, r=flip1995
Add lint to detect `allow` attributes without reason

I was considering putting this lint into the pedantic group. However, that would result in countless warnings for existing projects. Having it in restriction also seems good to me 🙃 (And now I need sleep 💤 )

---

changelog: New lint [`allow_lint_without_reason`] (Requires the `lint_reasons` feature)

Closes: rust-lang/rust-clippy#8502

b162b11abc Add recursive_format_impl lint
The to_string_in_display lint is renamed to recursive_format_impl
A check is added for the use of self formatted with Display or Debug
inside any format string in the same impl
The to_string_in_display check is kept as is - like in the
format_in_format_args lint

For now only Display and Debug are checked
This could also be extended to other Format traits (Binary, etc.)

093e32052e Auto merge of #8398 - Jarcho:unordered_transmute, r=llogiq
Add lint `transmute_undefined_repr`

Partially implements #3999 and #546

This doesn't consider `enum`s at all right now as those are going to be a pain to deal with. This also allows `#[repr(Rust)]` structs with only one non-zero sized fields. I think those are technically undefined when transmuted.

a6f80fccb1 new lint: single_char_lifetime_names
This pull request adds a lint against single character lifetime names, as they might not divulge enough information about the purpose of the lifetime. This can make code harder to understand. I placed this in `restriction` rather than `pedantic` (as suggested in #8233) since most of the Rust ecosystem already uses single character lifetime names (to my knowledge, at least) and since single character lifetime names aren't incorrect. I'd be happy to change this upon request, however. Fixes #8233.

- [x] Followed lint naming conventions
- [x] Added passing UI tests (including committed `.stderr` file)
- [x] `cargo test` passes locally
- [x] Executed `cargo dev update_lints`
- [x] Added lint documentation
- [x] Run `cargo dev fmt`

Warn on structs with a trailing zero-sized array but no `repr` attribute

Closes #2868

changelog: Implement ``[`trailing_empty_array`]``, which warns if a struct is defined where the last field is a zero-sized array but there are no `repr` attributes. Zero-sized arrays aren't very useful in Rust itself, so such a struct is likely being created to pass to C code or in some other situation where control over memory layout matters. Either way, a `repr` attribute is needed.

This is a configurable (no mod file/mod file) lint that determines if `mod.rs` is used consistently or if `mod.rs` is never used (using the new mod layout).

acdf43f257 Auto merge of #7225 - InquisitivePenguin:unnessecary-async, r=llogiq
New lint: `unused_async`

changelog: Adds a lint, `unused_async`, which checks for async functions with no await statements

`unused_async` is a lint that reduces code smell and overhead by encouraging async functions to be refactored into synchronous functions.

Fixes #7176

### Examples

```rust
async fn get_random_number() -> i64 {
    4 // Chosen by fair dice roll. Guaranteed to be random.
}
```

Could be written as:

```rust
fn get_random_number() -> i64 {
    4 // Chosen by fair dice roll. Guaranteed to be random.
}
```

Something like this, however, should **not** be caught by clippy:
```rust
#[async_trait]
trait AsyncTrait {
    async fn foo();
}

struct Bar;

#[async_trait]
impl AsyncTrait for Bar {
    async fn foo() {
        println!("bar");
    }
}
```

Fix duplicated "Rust 1.52" version section header
The most recent changelog update 037ddf282b accompanying the 1.52 release added a second "Rust 1.52" section header, with the result that the Rust release announcement https://blog.rust-lang.org/2021/05/06/Rust-1.52.0.html is linking to the "current beta" changelog section for Clippy rather than the stable changelog. I don't know the release process but based on previous changes to this file, I assume the correct thing to do is to mark the topmost section as being for Rust 1.53, not 1.52.

Lint: filter(Option::is_some).map(Option::unwrap)

Fixes #6061

*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog:
* add new lint for filter(Option::is_some).map(Option::unwrap)

First Rust PR, so I'm sure I've violated some idioms. Happy to change anything.

I'm getting one test failure locally -- a stderr diff for `compile_test`. I'm having a hard time seeing how I could be causing it, so I'm tentatively opening this in the hopes that it's an artifact of my local setup against `rustc`. Hoping it can at least still be reviewed in the meantime.

I'm gathering that since this is a method lint, and `.filter(...).map(...)` is already checked, the means of implementation needs to be a little different, so I didn't exactly follow the setup boilerplate. My way of checking for method calls seems a little too direct (ie, "is the second element of the expression literally the path for `Option::is_some`?"), but it seems like that's how some other lints work, so I went with it. I'm assuming we're not concerned about, eg, closures that just end up equivalent to `Option::is_some` by eta reduction.

As we discussed in [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20.236064/near/224647188) and [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20clippy.236064/near/224746333),   I start implementing this lint from the strictest version.
In this PR, I'll allow the below two cases to pass the lint to reduce FPs.

1. Appearances of unsuffixed numeric literals in `Local` if `Local` has a type annotation, for example:
```rust
// Good.
let x: i32 = 1;

// Also good.
let x: (i32, i32) = if cond {
   (1, 2)
} else {
   (2, 3)
};
```

2. Appearances of unsuffixed numeric literals in args of `Call` or `MethodCall`  if corresponding arguments of their signature have concrete types, for example:
```rust
fn foo_mono(x: i32) -> i32 {
    x
}

fn foo_poly<T>(t: T) -> t {
    t
}

// Good.
let x = foo_mono(13);

// Still bad.
let x: i32 = foo_poly(13);
```

New Lint: inspect_then_for_each

**Work In Progress**

This PR addresses [Issue 5209](https://github.com/rust-lang/rust-clippy/issues/5209) and adds a new lint called `inspect_then_for_each`.

Current seek some guidance.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- \[x] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`

[lint_naming]: https://rust-lang.github.io/rfcs/0344-conventions-galore.html#lints

This splits up clippy::collapsible_if into collapsible_if for
if x {
  if y { }
}
=>
if x && y { }

and collapsible_else_if for

if x {
} else {
 if y { }
}

=>
if x {

} else if y {

}

so that we can lint for only the latter but not the first if we desire.

attempt to implement if statement extraction and notice that we don't seem to handle unary ops correctly

add `maximum_unary_minus_right_tree` test and make it pass

add two tests and note one of them passes

filter out unary operations in several places, and find that the issue seems to be that we don't currently recognize the error in `multiple_comparison_types_and_unary_minus` even so.

remove tests that were deemed too much for now

run `cargo dev fmt`

correct eq_op post-merge

Add lint for 'field_reassign_with_default` #568

changelog: Add lint for field_reassign_with_default that checks if mutable object + field modification is used to edit a binding initialized with Default::default() instead of struct constructor.

Fixes #568

Notes:
- Checks for reassignment of one or more fields of a binding initialized with Default::default().
- Implemented using EarlyLintPass, might be future proofed better with LateLintPass.
- Does not trigger if Default::default() is used via another type implementing Default.
- This is a re-open of [PR#4761](https://github.com/rust-lang/rust-clippy/pull/4761), but I couldn't figure out how to re-open that one so here's a new one with the requested changes :S

Add new lint for undropped ManuallyDrop values

Adds a new lint for the following code:

```rust
struct S;

impl Drop for S {
    fn drop(&mut self) {
        println!("drip drop");
    }
}

fn main() {
    // This will not drop the `S`!!!
    drop(std::mem::ManuallyDrop::new(S));
    unsafe {
        // This will.
        std::mem::ManuallyDrop::drop(&mut std::mem::ManuallyDrop::new(S));
    }
}
```

The inner value of a `ManuallyDrop` will not be dropped unless the proper, unsafe drop function is called on it. This lint makes sure that a user does not accidently use the wrong function and forget to drop a `ManuallyDrop` value.

Fixes #5581.

e636b88aa1 Auto merge of #6044 - rschoon:rc-buffer, r=yaahc
Add `rc_buffer` lint for checking Rc<String> and friends

Fixes #2623

This is a bit different from the original PR attempting to implement this type of lint.   Rather than linting against converting into the unwanted types, this PR lints against declaring the unwanted type in a struct or function definition.

I'm reasonably happy with what I have here, although I used the fully qualified type names for the Path and OsString suggestions, and I'm not sure if I should have just used the short versions instead, even if they might not have been declared via use.

Also, I don't know if "buffer type" is the best way to put it or not.  Alternatively I could call it a "growable type" or "growable buffer type", but I was thinking of PathBuf when I started making the lint.

Add map_err_ignore lint

In a large code base a lot of times errors are ignored by using something like:

```rust
foo.map_err(|_| Some::Enum)?;
```

This drops the original error in favor of a enum that will not have the original error's context. This lint helps catch throwing away the original error in favor of an enum without its context.

Add lint panic in result

### Change
Adding a new "restriction" lint that will emit a warning when using "panic", "unimplemented" or "unreachable" in a function of type option/result.

### Motivation
Some codebases must avoid crashes at all costs, and hence functions of type option/result must return an error instead of crashing.

### Test plan
Running:
TESTNAME=panic_in_result cargo uitest ---

126790999a new lint: Returning unit from closures expecting Ord
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.

New lint: iter_next_slice

Hello, this is a work-in-progress PR for issue: https://github.com/rust-lang/rust-clippy/issues/5572

I have implemented lint to replace `iter().next()` for `slice[index..]` and `array` with `get(index)` and `get(0)` respectively. However since I made a lot of changes, I would like to request some feedback before continuing so that I could fix mistakes.

Thank you!

6c25c3c381 Lint for holding locks across await points
Fixes #4226

This introduces the lint await_holding_lock. For async functions, we iterate
over all types in generator_interior_types and look for types named MutexGuard,
RwLockReadGuard, or RwLockWriteGuard. If we find one then we emit a lint.

Rollup merge of #5248 - ThibsG:ConstValues, r=flip1995
Add lint on large non scalar const

This PR adds the new lint `non_scalar_const` that aims to warn against `const` declaration of large arrays. For performance, because of inlining, large arrays should be preferably declared as `static`.

Note: i made this one to warn on all const arrays, whether they are in a body function or not. I don't know if this is really necessary, i could just reduce this lint to variables out of function scope.

Fixes: #400

Result<T, E> has an `ok()` method that adapts a Result<T,E> into an Option<T>.
It's possible to get around this adapter by writing Result<T,E>.map_or(None, Some).

This lint is implemented as a new variant of the existing
[`option_map_none` lint](https://github.com/rust-lang/rust-clippy/pull/2128)

f5d0a452ba Add lint for pub fns returning a Result without documenting errors
The Rust Book recommends that functions that return a `Result` type have
a doc comment with an `# Errors` section describing the kind of errors
that can be returned
(https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections).
This change adds a lint to enforce this. The lint is allow by default;
it can be enabled with `#![warn(clippy::missing_errors_doc)]`.

Closes #4854.

cc622608db new lints around #[must_use] fns
`must_use_unit` lints unit-returning functions with a `#[must_use]`
attribute, suggesting to remove it.

`double_must_use` lints functions with a plain `#[must_use]`
attribute, but which return a type which is already `#[must_use]`,
so the attribute has no benefit.

`must_use_candidate` is a pedantic lint that lints functions and
methods that return some non-unit type that is not already
`#[must_use]` and suggests to add the annotation.

4fcaab3d62 Split redundant_closure lint
Move the method checking into a new lint called
`redundant_closures_for_method_calls` and put it in the pedantic group.

This aspect of the lint seems more controversial than the rest.

069957a8ad Add TransmutingNull Lint
* Late Lint pass, catches:
  * One liner: 0 -> null -> transmute
  * One liner: std:null() -> transmute
  * Const (which resolves to null) -> transmute
* UI Test case for Lint
* Updated test for issue 3849, because now the lint that code generated is in Clippy.
* Expanded `const.rs` miri-based Constant Folding code, to cover
  raw pointers
