84a60c3186 Prevent replace_consts lint within match patterns 
Currently `replace_consts` lint applies within match patterns but
the suggestion is incorrect as function calls are disallowed in
them. To fix this we prevent the lint from firing within patterns.

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)]`.

Add custom ICE message that points to Clippy repo 
This utilizes https://github.com/rust-lang/rust/pull/60584 by setting
our own `panic_hook` and pointing to our own issue tracker instead of
the rustc issue tracker.

This also adds a new internal lint to test the ICE message.

**Potential downsides**

* This essentially copies rustc's `report_ice` function as
  `report_clippy_ice`. I think that's how it's meant to be implemented, but
  maybe @jonas-schievink could have a look as well =)

  The downside of more-or-less copying this function is that we have to
  maintain it as well now.
  The original function can be found [here][original].
* `driver` now depends directly on `rustc` and `rustc_errors`

Closes #2734

Only emit `comparison_chain` lint, if `cmp` is actually available on the type being compared. Don't emit lint in cases where only `PartialOrd` is implemented.

I haven't yet fully understood [Adjustments](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/adjustment/struct.Adjustment.html). I would appreciate, if someone could double check whether my usage of [expr_ty](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/struct.TypeckTables.html#method.expr_ty) in `clippy_lints/src/comparison_chain.rs:91` is correct or if there are cases where using [expr_ty_adjusted](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/ty/struct.TypeckTables.html#method.expr_ty_adjusted) would lead to a different result when used with `utils::implements_trait`.

Fix Deprecated lints don't expand

### Move doc comments inside of declare_deprecated_lint macros so that they are picked up by lintlib.py

### fixes #4748

Unable to `cargo test` locally (I'm on NixOS, and keep getting errors that are similar to those #4714 might solve) but I have verified that all deprecated lints can now be expanded like other lints.

Add lint for debug_assert_with_mut_call

**What does not work:**

* detecting a mut call in the format string itself, e.g. `debug_assert!(false, "{}", vec![1].pop())`
* detecting `*mut T` usage (pointer)

changelog: In the suggestion of `explicit_counter_loop`, if the `for` loop argument doesn't implement `Iterator`, then we suggest `x.into_iter().enumerate()` (or `x.iter{_mut}()` as appropriate). Also, the span of the suggestion has been corrected.

This lint will complain when you put a mutable function/method call
inside a `debug_assert` macro, because it will not be executed in
release mode, therefore it will change the execution flow, which is not
wanted.

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.

Thank you for making Clippy better!

We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.

If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.

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)
- [ ] `cargo test` passes locally
- [x] Executed `./util/dev update_lints`
- [ ] Added lint documentation
- [ ] Run `./util/dev fmt`

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

Note that you can skip the above if you are just opening a WIP PR in
order to get feedback.

4c881d108a clippy::cargo_common_metadata: check for license-file 
When license property is missing in Cargo.toml check for license-file
as it may be used instead of the former. The check implemented here is
very naive as it only verifies that the field is present and is not
empty. More scrutiny can be applied by verifying the file is actually
present.

#4542 remove machine applicable suggestion

This helps #4542 (but does not completely resolve) by removing the machine applicable suggestion (which was incorrect) for that case.

I would have preferred to fix the machine applicable suggestion to handle format strings, but that's a bit beyond my current understanding of the clippy codebase. I'd be happy to give it a try given some guidance.

Changes cast-lossless to a pedantic lint

As discussed in #4528, this moves the cast-lossless lint from `all` to `pedantic`.

I couldn't tell from description alone if it should also be removed from the complexity category, so I left it as part of complexity for now. I didn't see any impact to the tests from this change, but I could be wrong (as this is my first PR).

fixes #4528

Allow block_in_if_{stmt,expr} in external macro

I found this by running `cargo fix --clippy` on quite a big codebase.

You could refactor this assert to
```rust
let block_expr = _;
assert!(block_expr);
```

but,
1. it doesn't increase the readability IMO
2. That isn't possible in a `debug_assert!`

I'm not sure though, if we should allow this for macros in general or just for external macros.

57c67a29d2 Auto merge of #4352 - phansch:fix_redundant_pattern_matching, r=flip1995 
Fix some suggestions for redundant_pattern_matching

.. and change the Applicability to `MaybeIncorrect`.

Fixes the problem displayed in https://github.com/rust-lang/rust-clippy/issues/4344#issuecomment-519206388.

We now append `{}` to the suggestion so that the conditional has the
correct syntax again.

(If we were to _remove_ the `if` instead, it would trigger the
`unused_must_use` warning for `#[must_use]` types.)

Add autofixable suggestion for unseparated integer literal suffixes

changelog: Add autofixable suggestion for unseparated integer literal suffixes

Somewhat WIP, since I haven't been able to get this working when adding `// run-rustfix` to `ui/literals.rs`. I think the issue is that there are multiple suggestions operating on one numerical literal, and I'm not sure what the best approach is to work around that.

Thanks

Thank you for making Clippy better!

We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.

If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.

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

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

new_ret_no_self: allow Self in inner type for impl Trait return types

Check the inner types of associated types of a trait when checking for Self in the return type of a `new` method. This means that the following will no longer warn:
```rust
trait Trait {
    type Inner;
}

struct S;

impl S {
    fn new() -> impl Trait<Inner = Option<Self>> {
        struct TraitImpl;

        impl Trait for TraitImpl {
            type Inner = Option<S>;
        }

        TraitImpl
    }
}
```
```rust
#![feature(async_await)]

struct Connection;

impl Connection {
    async fn new() -> Result<Self, ()> {
        Ok(S)
    }
}
```
closes #4359

changelog: fix `new_ret_no_self` lint for async `new` functions.

trait bounds lint - repeated types

This PR is to tackle https://github.com/rust-lang/rust-clippy/issues/3764 it's still a WIP and doesn't work but this is an initial stab. It builds though I haven't added any tests as I'm not sure where lint tests should go?

Unfortunately, it seems id isn't tied to the type itself but I guess where it is in the AST? Looking at https://manishearth.github.io/rust-internals-docs/syntax/ast/struct.Ty.html I can't see any members that would let me tell if a type was repeated in multiple trait bounds.

There may be other issues with how I've implemented this so any assistance is appreciated!

This lint adds warning if types are redundantly repeated in trait bounds i.e. `T: Copy, T: Clone` instead of `T: Copy + Clone`. This is a late pass trait lint and has necessitated the addition of code to allow hashing of TyKinds without taking into account Span information.

fixes #3988

changelog: Ignore generated fresh lifetimes in elision check.

**HELP**: It seems `tests/ui` are compiled under edition 2015, and I don't know how to add tests for this properly.

Here is the test input it had already passed:
```rust
#![feature(async_await)]
#![allow(dead_code)]

async fn sink1<'a>(_: &'a str) {} // lint
async fn sink1_elided(_: &str) {} // ok

async fn one_to_one<'a>(s: &'a str) -> &'a str { s } // lint
async fn one_to_one_elided(s: &str) -> &str { s } // ok
async fn all_to_one<'a>(a: &'a str, _b: &'a str) -> &'a str { a } // ok
// async fn unrelated(_: &str, _: &str) {} // Not allowed in async fn

// #3988
struct Foo;
impl Foo {
    pub async fn foo(&mut self) {} // ok
}

// rust-lang/rust#61115
async fn print(s: &str) { // ok
    println!("{}", s);
}

fn main() {}

cf81a3b6d0 Auto merge of #3832 - HarrisonMc555:use_last, r=flip1995 
Implement "Use last" lint

Closes #3673

This lint checks the use of `x.get(x.len() - 1)` and suggests `x.last()` (where `x` is a `Vec`).

There's at least one more thing that needs to happen here. I believe I am correctly checking most of the scenarios and avoiding false positives. However, if different `Vec`s are used for the `x.get` and `y.len`, then it will emit a false positive. In other words, I need to check to make sure the `Vec`s are the same.

Also, a lot of these commits were temporary and not helpful to the project history...am I supposed to squash on merge? If so, how do I do that?

Fix #4033 search_is_some

Fixes #4033.

Suggest `any(|x| ..)` instead of `any(|&x| ..)` for `find(|&x| ..).is_some()` (Lint [search_is_some](https://rust-lang.github.io/rust-clippy/master/index.html#search_is_some))

FnDecl of `find`:

```rust
fn find<P>(&mut self, mut p: P) -> Option<Self::Item> where
    P: FnMut(&Self::Item) -> bool
```

FnDecl of `any`:

```rust
fn any<F>(&mut self, mut f: F) -> bool where
    F: FnMut(Self::Item) -> bool
```

If match on `|&_|` in closure of `find`, only use `|_|` in the suggestion.

PS. It's the first time that I have used the `hir` API, please correct me if there is any mistake 😺

This passes all tests, including a new one specifically dealing with a type with interior mutability. The main thing I'm unsure of is whether the span I used in the call to `is_freeze` is the most appropriate span to use, or if it matters.

Should have been fixed by #919, however that focuses on const ctor expressions only, and `.or(Some(local))` isn't const.

This also automatically ignores things like `.or(Some(local.clone())` which we don't actually want to do; I need to figure out what to do here.

Change naive_bytecount applicability to MaybeIncorrect

We can't use `MachineApplicable` here as applying the fix will cause
another error because `bytecount` would first have to be added to the
Cargo.toml.

Example:

```
error: You appear to be counting bytes the naive way
  --> $DIR/bytecount.rs:5:13
   |
LL |     let _ = x.iter().filter(|&&a| a == 0).count(); // naive byte count
   |             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: Consider using the bytecount crate: `bytecount::count(x, 0)`
```

Just replacing it with the suggestion is not enough.

The second one is fixed with this commit: We just don't `expect`
anymore. If the snippet doesn't contain an `else`, we stop emitting the
lint because it's not a suspiciously formatted else anyway.

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

Fix ICE #3719+#3718 in lint match_ref_pats

Fixes #3719
This conveniently also fixes #3718

The ICE occurs when the match expression was a macro call, where the macro was defined in another file. Since we don't have the ability to reproduce this behavior with our UI tests (AFAIK), I couldn't add a test reproducing this ICE.. However, I added a test which is related to the ICE, to show the new behavior of the lint.

I tested it with the mscheme repo locally and the ICE didn't happen anymore.

I'm not sure if this was the correct approach.

I don't know if I put tests/ui/crashses/ice-3747.rs in correct place because the test always passed when I ran it with `cargo test`, even without the fix applied.

If I run that test with `env CLIPPY_TESTS=true cargo run --bin clippy-driver -- -L ./target/debug tests/ui/crashes/ice-3747.rs` then the test correctly fails without the fix applied

Don't check [print/write]_with_newline on raw strings

Some tests for #3778 and some maybe-not-the-greatest code that passes those tests!

I didn't run `fmt` because a) it doesn't seem to install on nightly for me, and b) on stable it wanted to apply formatting to over 90 files. Happy to make any tweaks though!

I suspect this contribution may require more than just tweaks. I'm still sort of new to rust so it may not be idiomatic, and the specific approach I took feels a little heavy-handed and brittle. I'm happy to make changes with some guidance, or equally happy if this gives a starting place for someone else to do it better :)

075c212849 Auto merge of #3776 - notriddle:drop-bounds, r=oli-obk 
Add a lint to warn on `T: Drop` bounds

**What it does:** Checks for generics with `std::ops::Drop` as bounds.

**Why is this bad?** `Drop` bounds do not really accomplish anything.
A type may have compiler-generated drop glue without implementing the
`Drop` trait itself. The `Drop` trait also only has one method,
`Drop::drop`, and that function is by fiat not callable in user code.
So there is really no use case for using `Drop` in trait bounds.

**Known problems:** None.

**Example:**
```rust
fn foo<T: Drop>() {}
```

ef72b2cac0 Check {print,write}_with_newline for literal newline 
Both regular strings and raw strings can contain literal newlines. This commit
extends the lint to also warn about terminating strings with these.

Behaviour handling for raw strings is also moved into `check_newlines` by
passing in the `is_raw` boolean from `check_tts` as
[suggested](https://github.com/rust-lang/rust-clippy/pull/3781#pullrequestreview-204663732)

3fa3bd8e94 Don't fail for raw string ending in \n 
Pass tests for #3778, {print,write}_with_newline false positive

This change guards the lint from checking newlines with a sort of complicated
check to see if it's a raw string. Raw strings shouldn't be newline-checked,
since r"\n" is literally \-n, not a newline. I think it's ok not to check for
_literal_ newlines at the end of raw strings, but maybe that's debatable.

I... don't think this code is that great. I wanted to write the check after
`check_tts`, but that was too late -- raw string type info is lost (or I
couldn't find it). Putting it inside `check_tts` feels heavy-duty and the check
itself feels like a brittle reach possibly into places it shouldn't.

Maybe someone can fix this up :)

Because the `constant` function doesn't handle const functions, we check if

Adding lint test for excessive LOC.

This is a WIP for #2377. Just wanted to pull in because I had a few questions:

1. Is it okay that I'm approaching this via counting by looking at each line in the snippet instead of looking at the AST tree? If there's another way to do it, I want to make sure I'm doing the correct way, but I wasn't sure since the output AST JSON doesn't seem to contain whitespace.

2. My function is definitely going to trigger the lint, so also wanted to see if there was something obvious I could do to reduce it.

3. Are the two tests fine, or is there something obvious I'm missing?

4. Obviously bigger question - am I approaching the line count correctly. Current strategy is count a line if it contains some code, so skip if it's just comments or empty.

Prevent incorrect cast_lossless suggestion in const_fn

`::from` is not a const fn, so applying the suggestion of
`cast_lossless` would fail to compile. The fix is to skip the lint if
the cast is found inside a const fn.

Fix automatic suggestion on `use_self`.

In an example like this:
```rust
impl Example {
    fn fun_1() { }
    fn fun_2() {
        Example::fun_1();
    }
}
```
Clippy tries to replace `Example::fun_1` with `Self`, loosing `::fun_1` in the process, it should rather try to replace `Example` with `Self`.

**Question**
- There may be other paths that need the same treatment, but I'm not sure I understand them fully:

67a9f20c91 Fix map_clone bad suggestion 
`cloned` requires that the elements of the iterator must be references. This
change determines if that is the case by examining the type of the closure
argument and suggesting `.cloned` only if it is a reference. When the closure
argument is not a reference, it suggests removing the `map` call instead.

A minor problem with this change is that the new check sometimes overlaps
with the `clone_on_copy` lint.

## Changes
- `cfg_attr_rustfmt`: Custom inner attributes are unstable. Let's disable the lint for inner attributes until [#54726](https://github.com/rust-lang/rust/issues/54726) stabilizes
- `collapsible_if`: unrelated cyclomatic_complexity warning that can be ignored
- `duration_subsec`: Simply needed `#![allow(dead_code)]`
- `excessive_precision`: Fixed by `#!allow(dead_code,unused_variables)`
- `explicit_write`: Fixed by `#![allow(unused_imports)]`
- `inconsistent_digit_grouping`: Avoid triggering `clippy::excessive_precision` lint
- `infallible_destructuring_match`: Fixed by `#![allow(dead_code, unreachable_code, unused_variables)]`
- `into_iter_on_ref`: Triggered unrelated `clippy::useless_vec` lint
- `large_digit_groups`: Avoid triggering `clippy::excessive_precision` lint
- `map_clone`: Fixed by `#![allow(clippy::iter_cloned_collect)]`
- `mem_replace`: Suggestion causes import to be unused, fixed by `#![allow(unused_imports)]`
- `precedence`: Allow some unrelated lints, and change out-of-range `0b1111_1111i8` literal
- `redundant_field_names`: Allow dead code, and remove stabilized feature toggles
- `replace_consts`: Fixed by `#![allow(unused_variables)]`
- `starts_ends_with`: Fixed by `#![allow(unused_must_use)]`
- `types`: Fixed by `#![allow(dead_code, unused_variables)]`
- `unit_arg`: Fixed by `#[allow(unused_must_use)]`

Restrict `use_self` on nested items

Fixes #3637
Fixes #3463

These changes make it so that nested items aren't visited any more by the `use_self` lint.

I think visiting nested items should be possible (so that it uses a different `item_path` for the nested item), but I'm not sure whether it's viable and what the best approach would be.
- Can `item_path` be changed to a new `Self` path before visiting the item, and then changing it back afterwards?
- Alternatively, could a new visitor be created, re-using `check_trait_method_impl_decl`?

Trigger `use_self` lint in local macros

Closes #2098

The test currently only covers local macros. #2098 suggested this:
> You could add the macro in question into the `mini_macro` subcrate

But that doesn't work for a `macro_rules`:
```
error: cannot export macro_rules! macros from a `proc-macro` crate type currently
```

So I suggest leaving out the test for external macros, as using `in_external_macro` seems straigtforward enough. Alternatives would be to use to add an additional crate (overkill if you ask me), or test with a `proc-macro`.

Fix if_same_then_else false positive

This fixes false positive in #3559.
The problem was that `SpanlessEq` does not check patterns in declarations. So this two blocks considered equal.
```rust
if true {
    let (x, y) = foo();
} else {
   let (y, x) = foo();
}
```
Not sure if the proposed change is safe as `SpanlessEq` is used extensively in other lints, but I tried hard to come up with counterexample and failed.

Fix wildcard_dependencies false positive 
This now only checks for wildcard_dependencies if the source is a
non-git source.

I tried adding a compiletest suite for the cargo lints, but I was unable
to override the `Cargo.toml` of the original executable.

I tested this manually by modifying the main `Cargo.toml`.

Downgrade unsafe_vector_initialization to restriction 
This lint looks for:

    let mut vec = Vec::with_capacity(len);
    vec.set_len(len);

The suggested replacement is `vec![0; len]`.

This is far too opinionated to be a deny-by-default lint because the performance
characteristics of the suggested replacement are totally different.

I am not convinced that this lint has value beyond what deny(unsafe_code) gives
you. Unsafe code is unsafe but please don't deny-by-default lint it if that's
the only reason.

Downgrade needless_pass_by_value to allow by default 
I noticed that I suppress this lint in many of my projects.

https://github.com/search?q=needless_pass_by_value+user%3Adtolnay&type=Code
https://github.com/search?q=needless_pass_by_value+user%3Aserde-rs&type=Code

Upon further inspection, this lint has a *long* history of false
positives (and several remaining).

Generally I feel that this lint is the definition of pedantic and should
not be linted by default.

RIIR update lints: Add check mode (update_lints.py rewrite complete) 
This finishes up the rewrite of `update_lints.py` in Rust. More
specifically, this

* adds the `--check` flag and handling to clippy_dev
* tracks file changes over the different calls to `replace_region_in_file`
* only writes changes to files if the `--check` flag is *not* used
* runs `./util/dev update_lints --check` on CI instead of the old script
* replaces usage of the `update_lints.py` script with an error

`./util/dev update_lints` behaves 99% the same as the python script.
The only difference that I'm aware of is an ordering change to
`clippy_lints/src/lib.rs` because underscores seem to be sorted
differently in Rust and in Python.

3353: float support added for mistyped_literal_suffixes lint r=mikerite a=Maxgy

I implemented the mistyped_literal_suffixes lint for float literals.

```
#![allow(unused_variables)]

fn main() {
    let x = 1E2_32;
    let x = 75.22_64;
}
```
Given the above, the additional check suggests the variables to be written as `let x = 1E2_f32` and `let x = 75.22_f64`.

0c1ffc1d1f Fix possible_missing_comma false positives 
`possible_missing_comma` should only trigger when the binary operator has
unary equivalent. Otherwise, it's not possible to insert a comma without
breaking compilation. The operators identified were `+`, `&`, `*` and `-`.

This fixes the specific examples given in issues #3244 and #3396
but doesn't address the conflict this lint has with the style of starting
a line with a binary operator.

3368: added downsides to "known problems" for get_unwrap lint r=flip1995 a=humean

As a beginner I found this lint to be confusing because I was not sure how the `Option` type disappeared as conceptually I know that my `.get()` and Index could fail. Initially I thought maybe the compiler or clippy was smart enough to understand that it was impossible for my `.get()` to fail in this particular case, but it was explained to me that using the Index syntax is just shorthand for directly unwrapping the value:

https://doc.rust-lang.org/src/std/collections/hash/map.rs.html#1547

For beginners or users trying to iterate quickly it seems common to litter your code with `unwrap` or `except` as placeholders for where some explicit error handling might need to take place. I think it should be warned that using Index is merely more concise, but doesn't at all reduce the risk of panics and might in fact cause you to miss handling them in a future refactor.

The update script now also generates the 'register_removed' section in
`clippy_lints/src/lib.rs`.

Also, instead of using `let mut store ...`, I added a new identifier
line so that the replacement will continue to work in case `let mut
store ...` ever changes.

3217: Fix string_lit_as_bytes lint for macros r=phansch a=yaahallo

Prior to this change, string_lit_as_bytes would trigger for constructs
like `include_str!("filename").as_bytes()` and would recommend fixing it
by rewriting as `binclude_str!("filename")`.

This change updates the lint to act as an EarlyLintPass lint. It then
differentiates between string literals and macros that have bytes
yielding alternatives.

Closes #3205

This PR adds lint `redundant_clone`. It suggests to remove redundant `clone()` that clones a owned value that will be dropped without any usage after that.

3338: new_ret_no_self false positives r=flip1995 a=JoshMcguigan

~~WORK IN PROGRESS~~

I plan to fix all of the false positives in #3313 in this PR, but I wanted to open it now to start gathering feedback.

In this first commit, I've updated the lint to allow tuple return types as long as `Self` shows up at least once, in any position of the tuple. I believe this is the broadest possible interpretation of what should be allowed for tuple return types, but I would certainly be okay making the lint more strict. 

fixes #3313

4b68c965fe Resolve ICE in needless range loop lint 
An ICE would occur if the needless range loop was triggered
within a procedural macro, because Clippy would try to produce
a code suggestion which was invalid, and caused the compiler
to crash.

This commit takes the same approach which Clippy currently takes
to work around this type of crash in the needless pass by value lint,
which is to skip the lint if Clippy is inside of a macro.

9bd4e5469e Don't suggest cloned() for map Box deref 
Boxes are a bit magic in that they need to use `*` to get an owned value
out of the box. They implement `Deref` but that only returns a
reference. This means an easy way to convert an `Option<Box<T>>` to an
`<Option<T>` is:

```
box_option.map(|b| *b)
```

However, since b36bb0a6 the `map_clone` lint is detecting this as an
attempt to copy the box. Fix by excluding boxes completely from the
deref part of this lint.

Fixes #3274

779988303a iter conservation efforts: save the endangered .iter() and .into_iter() 
Make explicit_iter_loop and explicit_into_iter_loop allow-by-default, so
that people can turn them on if they want to enforce that style; avoid
presenting them as *the* idiomatic Rust style, rather than just *a* style.

cc87dc7539 Move some range lints to complexity 
Recategorize `range_plus_one` and `range_minus_one` to `complexity`.
This moves `range_plus_one` out of the nursery as the inclusive range
syntax is now stable. Both are moved to `complexity` as it is more
consistent with other lints such as `int_plus_one`.

Remove incorrect note from string_add_assign docs 
The docs claim that `String::push_str` is better than `String::add` because `String::add` allocates a new string and drops the old one, but this is not true.  In fact, `add` reuses the existing string and grows it only if its capacity is exceeded, exactly like `push_str`.  Their performance is identical since `add` is just a wrapper for `push_str`:

```
    fn add(mut self, other: &str) -> String {
        self.push_str(other);
        self
    }
```

Add known problem to needless_borrow lint 
The `needless_borrow` lint is temporarily disabled because of some false
positives it causes in combination with the `derive` macro.

However the documentation does not explain these issues, but instead
lists `Known problems: None`. To make it clear why this lint is
currently not enabled, a description of the false positives caused by
this lint has been added to the `Known problems` section.

89a4558056 Add Known Problem for multiple lifetimes 2018-07-23 19:33:52 +10:00
Ryan Cumming
58459abd0c Allow pass by reference if we return a reference 
Currently this code will trigger `trivally_copy_pass_by_ref`:

```
struct OuterStruct {
    field: [u8; 8],
}

fn return_inner(outer: &OuterStruct) -> &[u8] {
    &outer.field
}
```

If we change the `outer` to be pass-by-value it will not live long
enough for us to return the reference. The above example is trivial but
I've hit this in real code that either returns a reference to either the
argument or in to `self`.

This suppresses the `trivally_copy_pass_by_ref` lint if we return a
reference and it has the same lifetime as the argument. This will likely
miss complex cases with multiple lifetimes bounded by each other but it
should cover the majority of cases with little effort.
