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 😺

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 `cargo fmt`

Note that you can skip the above if you are just opening a WIP PR in

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.

Fix false positive in module_name_repetitions lint

This lint was triggering on modules inside expanded attrs, like
for example `#[cfg(test)]` and possibly more.

It was not reporting a location in #3892 because `span.lo()` and `span.hi()` both were 0.

Fixes #3892

Allow allowing of toplevel_ref_arg lint

lint level attributes, but this commit makes the lint level attributes
work for `toplevel_ref_arg`.

Add Lint PathBufPushOverwrite

Closes #3923

This is a very simple Lint that checks if push is being called with a Root Path. Because that can make it overwrite the previous path.

I used std::path::Path to check if it's root, in order to keep it working across windows/linux environments instead of checking for '/'. Is that alright?

On the `if_chain!` block, Is there a way to make it short while getting the value of the first argument? I got the example from other lints.

Note that this is first Lint, I hope I got everything covered  🚀

Fix `explicit_counter_loop` suggestion

#1670

This code seems to me to work, but I have two question.
* Because range expression desugared in hir, `Sugg::hir` doesn't add parenthesis to range expression.  Which function is better to check range do you think, `check_for_loop_explicit_counter` or `hir_from_snippet`?
* Do you think we need to distinguish between range expression and struct expression that creates `std::ops::Range*`?

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 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

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 :)

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>() {}

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.

a40d8e4479 Auto merge of #3679 - daxpedda:use_self, r=phansch
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:
  - e648adf086/clippy_lints/src/use_self.rs (L94-L96)

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.

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`?

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.

Makes `redundant_clone` warn on unnecessary `foo.field.clone()` sometimes (it can detect an unnecessary clone only if the base of projection, `foo` in this case, is not used at all after that). This is enough for cases like `returns_tuple().0.clone()`.

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`.

Fixes #3167

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.

Prior to this change, string_lit_as_bytes would trigger for constructs

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

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.

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.

fedd3ef711 Allows neg_cmp_op_on_partial_ord for external macros (fixes #2856).
The macro always negates the result of the given comparison in its
internal check which automatically triggered the lint. As its an
external macro there was no chance to do anything about it which lead
to a white listing of all external macros to prevent further issues.

Removing lint for constant usize array indexing
This commit removes the logic in this PR that linted out-of-bounds constant `usize` indexing on arrays. That case is already handled by rustc's `const_err` lint. Beyond removing the linting logic, the test file and its associated stderr were updated to verify that const `usize` indexing operations on arrays are no longer handled by this `indexing_slicing` lint.

Add tests that index with a const value.
In this commit tests were added to ensure that tests with a `const` index behaved as expected.
In order to minimize the changes to the test's corresponding `stderr`, the tests were appended to
the end of the file.

Revisiting indexing_slicing test cases
This commit contains a few changes. In an attempt to clarify which test cases should and should not produce stderr it became clear that some cases were being handled incorrectly. In order to address these test cases, a minor re-factor was made to the linting logic itself.

The re-factor was driven by edge case handling including a need for additional match conditions for `ExprCall` (`&x[0..=4]`) and `ExprBinary` (`x[1 << 3]`). Rather than attempt to account for each potential `Expr*` the code was re-factored into simply "if ranged index" and an "otherwise" conditions.

Second pass at addressing changes requested
The changes reflected in this commit (requested in PR #2790) are as follows:

- Extended `INDEXING_SLICING` documentation to include the array type so that it is clearer when indexing operations are allowed.
- Variable `ty` defined identically in multiple scopes was moved to an outer scope so it's only defined once.
- Added a missing return statement to ensure only one lint is triggered by a scenario.
- Prettified match statement with a `let` clause. (I learned something new!)
- Added `&x[5..].iter().map(|x| 2 * x).collect::<Vec<i32>>()` and `&x[2..].iter().map(|x| 2 * x).collect::<Vec<i32>>()` to the test cases. The first _should trigger the lint/stderr_ and the second _should not_.

This commit represents an attempt to address changes requested in the process of reviewing PR #2790.
The changes reflected in this commit are as follows:

- Revised `IndexingSlicingPass` struct name to IndexingSlicing for consistency with the rest of the code base.
- Revised match arm condition to use `(..)` shorthand in favor of `(_, _, _)`.
- Restored a couple telling variable names.
- Calls to `cx.span_lint` were revised to use `utils::span_help_and_lint`.
- Took a stab at refactoring some generalizable calls to `utils::span_help_and_lint` to minimize duplicate code.
- Revised INDEXING_SLICING declaration to pedantic rather than restriction.
- Added `&x[0..].get(..3)` to the test cases.

Rename instances of array_indexing
This commit renames instances of `array_indexing` to `indexing_slicing` and moves the `indexing_slicing` lint to the `clippy_pedantic` group. The justification for this commit's changes are detailed in the previous commit's message.

Extend indexing_slicing lint
Hey there clippy team! I've made some assumptions in this PR and I'm not at all certain they'll look like the right approach to you. I'm looking forward to any feedback or revision requests you have, thanks!

    Prior to this commit the `indexing_slicing` lint was limited to indexing/slicing operations on arrays. This meant that the scope of a really useful lint didn't include vectors. In order to include vectors in the `indexing_slicing` lint a few steps were taken.

    The `array_indexing.rs` source file in `clippy_lints` was renamed to `indexing_slicing.rs` to more accurately reflect the lint's new scope. The `OUT_OF_BOUNDS_INDEXING` lint persists through these changes so if we can know that a constant index or slice on an array is in bounds no lint is triggered.

    The `array_indexing` tests in the `tests/ui` directory were also extended and moved to `indexing_slicing.rs` and `indexing_slicing.stderr`.

    The `indexing_slicing` lint was moved to the `clippy_pedantic` lint group.

    A specific "Consider using" string was added to each of the `indexing_slicing` lint reports.

    At least one of the test scenarios might look peculiar and I'll leave it up to y'all to decide if it's palatable. It's the result of indexing the array `x` after `let x = [1, 2, 3, 4];`

    ```
    error: slicing may panic. Consider using `.get(..n)`or `.get_mut(..n)`instead
      --> $DIR/indexing_slicing.rs:23:6
       |
    23 |     &x[0..][..3];
       |      ^^^^^^^^^^^
    ```

    The error string reports only on the second half's range-to, because the range-from is in bounds!

    Again, thanks for taking a look.

    Closes #2536

This checks for things like

    if x.is_some() {

    }

which should be written using `if let` or `match` instead.

In the process I moved some logic to determine which variables are
mutated in an expression to utils/usage.rs.

5379fc1b28 better parsing of condition in while loop for mutability
allow condition to be a block: by calling visit_expr of the visitor directly on the condition instead of walk_expr on the whole expression, we bypass the match to ExprWhile that calls visit_expr on the condition and visit_block on the body. This allow to re-enable visit_block in the visitor, as it won't be called on the while body
allow condition to use static variables: maintain a list of static variables used, and if they are mutable

Fix useless_format false positive with macros
Clippy was issuing a warning when `format!` was used inside a macro.
That's a problem because macros have different syntax and can be outside
the control of the user.

This skips the `useless_format` check if the `format!` call is inside a
macro.

Fix false positive in empty_line_after_outer_attr
Before, when you had a block comment between an attribute and the
following item like this:

```rust
\#[crate_type = "lib"]
/*

*/
pub struct Rust;
```

It would cause a false positive on the lint, because there is an empty
line inside the block comment.

This makes sure that basic block comments are detected and removed from
the snippet that was created before.

Fix false positive in empty_line_after_outer_attribute
`empty_line_after_outer_attribute` produced a false positive warning when
deriving `Copy` and/or `Clone` for an item.

It looks like the second point in [this comment][that_comment] is related,
as the attribute that causes the false positive has a path of
`rustc_copy_clone_marker`.

Fixes #2475

8494f57c82 Fix author lint
The author lint was generating invalid code as shown on issue:
https://github.com/rust-lang-nursery/rust-clippy/issues/2442

I've changed the generated code to properly track cast
expressions.

Unfortunatelly, I've had to rewrite the `visit_decl` method, to
avoid that last if of the chain will be added. After looking at the code,
this last line was being added because of the `let x: char` part, but not
because of the `0x45df as char` expression.

It seems that let statements should not generate code on the author
lint, but I'm not sure that this is true or if I'm breaking
something on other code generation parts.

Finally, I've added a test for the author lint, but I'm not sure that
this needs to be added to the testsuite.

Lint multiline attributes properly
This makes it so that the `empty_line_after_outer_attribute` lint only
checks for newlines between the end of the attribute and the beginning
of the following item.

We need to check for the empty line count being bigger than 2 because
now the snippet of valid code contains only `\n` and splitting it
produces `["", ""]`
Invalid code will contain more than 2 empty strings.

Partly fix incorrect useless_attribute suggestion
This fixes an incorrect suggestion from the `useless_attribute` lint
when using `cfg_attr`.

Additionally, it will not show a suggestion anymore, if the attribute
begins on a previous line, because it is much harder to construct the
span of multi-line `cfg_attr` attributes as they don't appear in the AST.

To fix it completely, one would have to parse upwards into the file,
and find the beginning of the `cfg_attr` attribute.

Fix false positive in empty_line_after_outer_attr
Doc comments are syntactic sugar for #[doc] attributes, so this lint was
catching them, too.

This commit makes it so that doc comments are ignored in this lint.

I think, for normal attributes it makes sense to warn about following empty
lines, for doc comments, less. This way the user has some freedom over
the formatting.

7467b83377 Suggest removing inline attributes
This adds a `suggest_remove_item` helper that will remove an item and
all trailing whitespace. This should handle both attributes on the same
line as the function and on a separate line; the function takes the
position of the original attribute.

5f3c340bfb Lint for trait methods without bodies
As discussed in rust-lang/rust#47475 the #[inline] attribute is
currently allowed on trait methods without bodies (i.e. without a
default implementation). This is misleading as it could be interpreted
as affecting the implementations of the trait method. Add a lint for any
use of #[inline] on a trait method without a body.

Fixes rust-lang/rust#47475
