Auto merge of #115183 - flip1995:clippyup, r=Manishearth,oli-obk
Update Clippy
r? `@oli-obk` Assigning you, because something broke with ui_test:
```
tests/ui/crashes/ice-7272.rs FAILED:
command: "<unknown>"
A bug in `ui_test` occurred: called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
full stderr:
```
(and that 103 times)
Thought I would ping you, before starting to investigate. Maybe you know what's going on.

# Define New Lints
|
||||
|
||||
The first step in the journey of a new lint is the definition
|
||||
and registration of the lint in Clippy's codebase.
|
||||
We can use the Clippy dev tools to handle this step since setting up the
|
||||
lint involves some boilerplate code.
|
||||
|
||||
#### Lint types
|
||||
|
||||
A lint type is the category of items and expressions in which your lint focuses on.
|
||||
|
||||
As of the writing of this documentation update, there are 12 _types_ of lints
|
||||
besides the numerous standalone lints living under `clippy_lints/src/`:
|
||||
|
||||
- `cargo`
|
||||
- `casts`
|
||||
- `functions`
|
||||
- `loops`
|
||||
- `matches`
|
||||
- `methods`
|
||||
- `misc_early`
|
||||
- `operators`
|
||||
- `transmute`
|
||||
- `types`
|
||||
- `unit_types`
|
||||
- `utils / internal` (Clippy internal lints)
|
||||
|
||||
These types group together lints that share some common behaviors. For instance,
|
||||
`functions` groups together lints that deal with some aspects of functions in
|
||||
Rust, like definitions, signatures and attributes.
|
||||
|
||||
For more information, feel free to compare the lint files under any category
|
||||
with [All Clippy lints][all_lints] or ask one of the maintainers.
|
||||
|
||||
## Lint name
|
||||
|
||||
A good lint name is important, make sure to check the [lint naming
|
||||
guidelines][lint_naming]. Don't worry, if the lint name doesn't fit, a Clippy
|
||||
team member will alert you in the PR process.
|
||||
|
||||
---
|
||||
|
||||
We'll name our example lint that detects functions named "foo" `foo_functions`.
|
||||
Check the [lint naming guidelines][lint_naming] to see why this name makes
|
||||
sense.
|
||||
|
||||
## Add and Register the Lint
|
||||
|
||||
Now that a name is chosen, we shall register `foo_functions` as a lint to the
|
||||
codebase. There are two ways to register a lint.
|
||||
|
||||
### Standalone
|
||||
|
||||
If you believe that this new lint is a standalone lint (that doesn't belong to
|
||||
any specific [type](#lint-types) like `functions` or `loops`), you can run the
|
||||
following command in your Clippy project:
|
||||
|
||||
```sh
|
||||
$ cargo dev new_lint --name=lint_name --pass=late --category=pedantic
|
||||
```
|
||||
|
||||
There are two things to note here:
|
||||
|
||||
1. `--pass`: We set `--pass=late` in this command to do a late lint pass. The
|
||||
alternative is an `early` lint pass. We will discuss this difference in a
|
||||
later chapter.
|
||||
<!-- FIXME: Link that "later chapter" when lint_passes.md is merged -->
|
||||
2. `--category`: If not provided, the `category` of this new lint will default
|
||||
to `nursery`.
|
||||
|
||||
The `cargo dev new_lint` command will create a new file:
|
||||
`clippy_lints/src/foo_functions.rs` as well as [register the
|
||||
lint](#lint-registration).
|
||||
|
||||
Overall, you should notice that the following files are modified or created:
|
||||
|
||||
```sh
|
||||
$ git status
|
||||
On branch foo_functions
|
||||
Changes not staged for commit:
|
||||
(use "git add <file>..." to update what will be committed)
|
||||
(use "git restore <file>..." to discard changes in working directory)
|
||||
modified: CHANGELOG.md
|
||||

|
||||
modified: clippy_lints/src/lib.register_pedantic.rs
|
||||
modified: clippy_lints/src/lib.rs
|
||||
|
||||
Untracked files:
|
||||
(use "git add <file>..." to include in what will be committed)
|
||||
clippy_lints/src/foo_functions.rs
|
||||
tests/ui/foo_functions.rs
|
||||
```
|
||||
|
||||
|
||||
### Specific Type
|
||||
|
||||
> **Note**: Lint types are listed in the ["Lint types"](#lint-types) section
|
||||
|
||||
If you believe that this new lint belongs to a specific type of lints,
|
||||
you can run `cargo dev new_lint` with a `--type` option.
|
||||
|
||||
Since our `foo_functions` lint is related to function calls, one could
|
||||
argue that we should put it into a group of lints that detect some behaviors
|
||||
of functions, we can put it in the `functions` group.
|
||||
|
||||
Let's run the following command in your Clippy project:
|
||||
|
||||
```sh
|
||||
$ cargo dev new_lint --name=foo_functions --type=functions --category=pedantic
|
||||
```
|
||||
|
||||
This command will create, among other things, a new file:
|
||||
`clippy_lints/src/{type}/foo_functions.rs`.
|
||||
In our case, the path will be `clippy_lints/src/functions/foo_functions.rs`.
|
||||
|
||||
Notice how this command has a `--type` flag instead of `--pass`. Unlike a standalone
|
||||
definition, this lint won't be registered in the traditional sense. Instead, you will
|
||||
call your lint from within the type's lint pass, found in `clippy_lints/src/{type}/mod.rs`.
|
||||
|
||||
A _type_ is just the name of a directory in `clippy_lints/src`, like `functions` in
|
||||
the example command. Clippy groups together some lints that share common behaviors,
|
||||
so if your lint falls into one, it would be best to add it to that type.
|
||||
|
||||
Overall, you should notice that the following files are modified or created:
|
||||
|
||||
```sh
|
||||
$ git status
|
||||
On branch foo_functions
|
||||
Changes not staged for commit:
|
||||
(use "git add <file>..." to update what will be committed)
|
||||
(use "git restore <file>..." to discard changes in working directory)
|
||||
modified: CHANGELOG.md
|
||||
modified: clippy_lints/src/declared_lints.rs
|
||||
modified: clippy_lints/src/functions/mod.rs
|
||||
|
||||
Untracked files:
|
||||
(use "git add <file>..." to include in what will be committed)
|
||||
clippy_lints/src/functions/foo_functions.rs
|
||||
tests/ui/foo_functions.rs
|
||||
```
|
||||
|
||||
|
||||
## The `define_clippy_lints` macro
|
||||
|
||||
After `cargo dev new_lint`, you should see a macro with the name
|
||||
`define_clippy_lints`. It will be in the same file if you defined a standalone
|
||||
lint, and it will be in `mod.rs` if you defined a type-specific lint.
|
||||
|
||||
The macro looks something like this:
|
||||
|
||||
```rust
|
||||
declare_clippy_lint! {
|
||||
/// ### What it does
|
||||
///
|
||||
/// // Describe here what does the lint do.
|
||||
///
|
||||
/// Triggers when detects...
|
||||
///
|
||||
/// ### Why is this bad?
|
||||
///
|
||||
/// // Describe why this pattern would be bad
|
||||
///
|
||||
/// It can lead to...
|
||||
///
|
||||
/// ### Example
|
||||
/// ```rust
|
||||
/// // example code where clippy issues a warning
|
||||
/// ```
|
||||
/// Use instead:
|
||||
/// ```rust
|
||||
/// // example code which does not raise clippy warning
|
||||
/// ```
|
||||
#[clippy::version = "1.70.0"] // <- In which version was this implemented, keep it up to date!
|
||||
pub LINT_NAME, // <- The lint name IN_ALL_CAPS
|
||||
pedantic, // <- The lint group
|
||||
"default lint description" // <- A lint description, e.g. "A function has an unit return type."
|
||||
}
|
||||
```
|
||||
|
||||
## Lint registration
|
||||
|
||||
If we run the `cargo dev new_lint` command for a new lint, the lint will be
|
||||
automatically registered and there is nothing more to do.
|
||||
|
||||
However, sometimes we might want to declare a new lint by hand. In this case,
|
||||
we'd use `cargo dev update_lints` command afterwards.
|
||||
|
||||
When a lint is manually declared, we might need to register the lint pass
|
||||
manually in the `register_plugins` function in `clippy_lints/src/lib.rs`:
|
||||
|
||||
```rust
|
||||
store.register_late_pass(|_| Box::new(foo_functions::FooFunctions));
|
||||
```
|
||||
|
||||
As you might have guessed, where there's something late, there is something
|
||||
early: in Clippy there is a `register_early_pass` method as well. More on early
|
||||
vs. late passes in a later chapter.
|
||||
<!-- FIXME: Link that "later chapter" when lint_passes.md is merged -->
|
||||
|
||||
Without a call to one of `register_early_pass` or `register_late_pass`, the lint
|
||||
pass in question will not be run.

# Method Checking
|
||||
|
||||
In some scenarios we might want to check for methods when developing
|
||||
a lint. There are two kinds of questions that we might be curious about:
|
||||
|
||||
- Invocation: Does an expression call a specific method?
|
||||
- Definition: Does an `impl` define a method?
|
||||
|
||||
## Checking if an `expr` is calling a specific method
|
||||
|
||||
Suppose we have an `expr`, we can check whether it calls a specific
|
||||
method, e.g. `our_fancy_method`, by performing a pattern match on
|
||||
the [`ExprKind`] that we can access from `expr.kind`:
|
||||
|
||||
```rust
|
||||
use rustc_hir as hir;
|
||||
use rustc_lint::{LateContext, LateLintPass};
|
||||
use rustc_span::sym;
|
||||
use clippy_utils::is_trait_method;
|
||||
|
||||
impl<'tcx> LateLintPass<'tcx> for OurFancyMethodLint {
|
||||
fn check_expr(&mut self, cx: &LateContext<'tcx>, expr: &'tcx hir::Expr<'_>) {
|
||||
// Check our expr is calling a method with pattern matching
|
||||
if let hir::ExprKind::MethodCall(path, _, [self_arg, ..]) = &expr.kind
|
||||
// Check if the name of this method is `our_fancy_method`
|
||||
&& path.ident.name == sym!(our_fancy_method)
|
||||
// We can check the type of the self argument whenever necessary.
|
||||
// (It's necessary if we want to check that method is specifically belonging to a specific trait,
|
||||
// for example, a `map` method could belong to user-defined trait instead of to `Iterator`)
|
||||
// See the next section for more information.
|
||||
&& is_trait_method(cx, self_arg, sym::OurFancyTrait)
|
||||
{
|
||||
println!("`expr` is a method call for `our_fancy_method`");
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Take a closer look at the `ExprKind` enum variant [`MethodCall`] for more
|
||||
information on the pattern matching. As mentioned in [Define
|
||||
Lints](defining_lints.md#lint-types), the `methods` lint type is full of pattern
|
||||
matching with `MethodCall` in case the reader wishes to explore more.
|
||||
|
||||
Additionally, we use the [`clippy_utils::sym!`][sym] macro to conveniently
|
||||
convert an input `our_fancy_method` into a `Symbol` and compare that symbol to
|
||||
the [`Ident`]'s name in the [`PathSegment`] in the [`MethodCall`].
|
||||
|
||||
## Checking if a `impl` block implements a method
|
||||
|
||||
While sometimes we want to check whether a method is being called or not, other
|
||||
times we want to know if our `Ty` defines a method.
|
||||
|
||||
To check if our `impl` block defines a method `our_fancy_method`, we will
|
||||
utilize the [`check_impl_item`] method that is available in our beloved
|
||||
[`LateLintPass`] (for more information, refer to the ["Lint
|
||||
Passes"](lint_passes.md) chapter in the Clippy book). This method provides us
|
||||
with an [`ImplItem`] struct, which represents anything within an `impl` block.
|
||||
|
||||
Let us take a look at how we might check for the implementation of
|
||||
`our_fancy_method` on a type:
|
||||
|
||||
```rust
|
||||
use clippy_utils::ty::is_type_diagnostic_item;
|
||||
use clippy_utils::return_ty;
|
||||
use rustc_hir::{ImplItem, ImplItemKind};
|
||||
use rustc_lint::{LateContext, LateLintPass};
|
||||
use rustc_span::symbol::sym;
|
||||
|
||||
impl<'tcx> LateLintPass<'tcx> for MyTypeImpl {
|
||||
fn check_impl_item(&mut self, cx: &LateContext<'tcx>, impl_item: &'tcx ImplItem<'_>) {
|
||||
// Check if item is a method/function
|
||||
if let ImplItemKind::Fn(ref signature, _) = impl_item.kind
|
||||
// Check the method is named `our_fancy_method`
|
||||
&& impl_item.ident.name == sym!(our_fancy_method)
|
||||
// We can also check it has a parameter `self`
|
||||
&& signature.decl.implicit_self.has_implicit_self()
|
||||
// We can go even further and even check if its return type is `String`
|
||||
&& is_type_diagnostic_item(cx, return_ty(cx, impl_item.hir_id), sym::String)
|
||||
{
|
||||
println!("`our_fancy_method` is implemented!");
|
||||
}
|
||||
}
|
||||
}

|
||||
/// (e.g. `fn() -> impl Deref + DerefMut<Target = i32>` has an unnecessary `Deref` bound,

/// This lint does not check for implied bounds transitively. Meaning that

/// it does't check for implied bounds from supertraits of supertraits

/// Box::new(123)

/// }
