Summary

This happens since nightly-2023-04-14 maybe some rustc change regressed this?

where
    F: FnMut(&'a mut i32) -> R,

Yes, it's rust-lang/rust#110220.

@lcnr, what are your thoughts about constructing a TypeErrCtxt for cases like lints?

@compiler-errors

Actually, there really is just one case in clippy that does this. I think we may just need to regress the clippy lint's notes and keep the err_ctxt() behavior.

Looks like src/tools/clippy/tests/ui/crashes/ice-5207.rs would have actually caught this if we had run all lints on it

// Regression test for https://github.com/rust-lang/rust-clippy/issues/5207

pub async fn bar<'a, T: 'a>(_: T) {}

fn main() {}

but the lint is still in nursery :/

meh 😅 i see why'd want to use TypeErrCtxt for lints as well, so I am fine with reverting the change to add a delay_span_bug

Independent repro, that has an await point (if useful):

#![warn(clippy::future_not_send)]

pub async fn foo(_bar: impl AsRef<[u8]>) {
    async {}.await;
}

(edit: it probably doesn't help, since the await point doesn't really do anything)

Special-case item attributes in the suggestion output

resolve: Pre-compute non-reexport module children

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list.
They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Alloc `hir::Lit` in an arena to remove the destructor from `Expr`

This allows allocating `Expr`s into a dropless arena, which is useful
for using length prefixed thing slices in HIR, since these can only be
allocated in the dropless arena and not in a typed arena. This is
something I'm working on.

Restrict `From<S>` for `{D,Subd}iagnosticMessage`.

Currently a `{D,Subd}iagnosticMessage` can be created from any type that
impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static,
str>`, which are reasonable. It also includes `&String`, which is pretty
weird, and results in many places making unnecessary allocations for
patterns like this:
```
self.fatal(&format!(...))
```
This creates a string with `format!`, takes a reference, passes the
reference to `fatal`, which does an `into()`, which clones the
reference, doing a second allocation. Two allocations for a single
string, bleh.

This commit changes the `From` impls so that you can only create a
`{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static,
str>`. This requires changing all the places that currently create one
from a `&String`. Most of these are of the `&format!(...)` form
described above; each one removes an unnecessary static `&`, plus an
allocation when executed. There are also a few places where the existing
use of `&String` was more reasonable; these now just use `clone()` at
the call site.

As well as making the code nicer and more efficient, this is a step
towards possibly using `Cow<'static, str>` in
`{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing
the `From<&'a str>` impls to `From<&'static str>`, which is doable, but
I'm not yet sure if it's worthwhile.

Use `Cow` in `{D,Subd}iagnosticMessage`.

Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment:
```
// FIXME(davidtwco): can a `Cow<'static, str>` be used here?
```
This commit answers that question in the affirmative. It's not the most
compelling change ever, but it might be worth merging.

This requires changing the `impl<'a> From<&'a str>` impls to `impl
From<&'static str>`, which involves a bunch of knock-on changes that
require/result in call sites being a little more precise about exactly
what kind of string they use to create errors, and not just `&str`. This
will result in fewer unnecessary allocations, though this will not have
any notable perf effects given that these are error paths.

Note that I was lazy within Clippy, using `to_string` in a few places to
preserve the existing string imprecision. I could have used `impl
Into<{D,Subd}iagnosticMessage>` in various places as is done in the
compiler, but that would have required changes to *many* call sites
(mostly changing `&format("...")` to `format!("...")`) which didn't seem
worthwhile.

Fix failing clippy tests

Comments out the C string literals due to rust-lang/rust#113334

Fixes rust-lang#11121

Rename `adjustment::PointerCast` and variants using it to `PointerCoercion`

It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related
casts, when in reality their just used to share a some enum variants. Make it clear there these
are only coercion to make it clear why only some pointer related "casts" are in the enum.

Delete `to_string_in_format_args_incremental.rs`

It fails CI and passes locally. It passes random directores in
`-Cincremental` so maybe something's up. It shouldn't block us here.

Drop uplifted `clippy::fn_null_check`

Ignore flaky clippy tests.

Suggest the correct variable name for `manual_let_else`

Search for inactive `cfg` attributes and empty macro expansion through
the entire block

Slightly refactor constant evaluation and add detection for empty macro expansion and `cfg`ed statements.

Improve `SpanlessEq`
* Don't consider expansions of different macros to be the same, even if they expand to the same tokens
* Don't consider `cfg!` expansions to be equal if they check different configs.

enhance `needless_collect`

Updates `needless_collect` to lint for collecting into a method or
function argument thats taking an `IntoIterator` (for example `extend`).
Every `Iterator` trivially implements `IntoIterator` and colleting it
only causes an unnecessary allocation.

Add new `UNIQUE_CFG_CONDITION` lint

Add UI test for UNIQUE_CFG_CONDITION

Update CHANGELOG

Add check for empty cfg `all` condition

Update urls in Type Checking

Bump nightly version -> 2023-05-20

[`match_wild_err_arm`]: do not lint in const contexts

consider array initializer for `large_stack_arrays`

add test case for rust-lang#10741

Unit tests highlighting unsafe match issue

These unit tests generate non-compilable code.  I did NOT `bless` them on purpose because the stderr output is not good.

I'm surprised we don't auto-compile the suggestions here - is this something that can be easily enabled?

See rust-lang#10808

Fix formatting of if let chain

Some improvements to the manual_let_else lint suggestions

* Replace variables inside | patterns in the if let: let v = if let V::A(v) | V::B(v) = v { v } else ...
* Support nested patterns: let v = if let Ok(Ok(Ok(v))) = v { v } else ...
* Support tuple structs with more than one arg: let v = V::W(v, _) = v { v } else ...
* Correctly handle .. in tuple struct patterns: let v = V::X(v, ..) = v { v } else ...

Special-case item attributes in the suggestion output

resolve: Pre-compute non-reexport module children

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list.
They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Alloc `hir::Lit` in an arena to remove the destructor from `Expr`

This allows allocating `Expr`s into a dropless arena, which is useful
for using length prefixed thing slices in HIR, since these can only be
allocated in the dropless arena and not in a typed arena. This is
something I'm working on.

clean up Colon from clippy

Restrict `From<S>` for `{D,Subd}iagnosticMessage`.

Currently a `{D,Subd}iagnosticMessage` can be created from any type that
impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static,
str>`, which are reasonable. It also includes `&String`, which is pretty
weird, and results in many places making unnecessary allocations for
patterns like this:
```
self.fatal(&format!(...))
```
This creates a string with `format!`, takes a reference, passes the
reference to `fatal`, which does an `into()`, which clones the
reference, doing a second allocation. Two allocations for a single
string, bleh.

This commit changes the `From` impls so that you can only create a
`{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static,
str>`. This requires changing all the places that currently create one
from a `&String`. Most of these are of the `&format!(...)` form
described above; each one removes an unnecessary static `&`, plus an
allocation when executed. There are also a few places where the existing
use of `&String` was more reasonable; these now just use `clone()` at
the call site.

As well as making the code nicer and more efficient, this is a step
towards possibly using `Cow<'static, str>` in
`{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing
the `From<&'a str>` impls to `From<&'static str>`, which is doable, but
I'm not yet sure if it's worthwhile.

Tweak output for 'add line' suggestion

Special-case item attributes in the suggestion output

resolve: Pre-compute non-reexport module children

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list.
They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Alloc `hir::Lit` in an arena to remove the destructor from `Expr`

This allows allocating `Expr`s into a dropless arena, which is useful
for using length prefixed thing slices in HIR, since these can only be
allocated in the dropless arena and not in a typed arena. This is
something I'm working on.

clean up Colon from clippy

Restrict `From<S>` for `{D,Subd}iagnosticMessage`.

Currently a `{D,Subd}iagnosticMessage` can be created from any type that
impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static,
str>`, which are reasonable. It also includes `&String`, which is pretty
weird, and results in many places making unnecessary allocations for
patterns like this:
```
self.fatal(&format!(...))
```
This creates a string with `format!`, takes a reference, passes the
reference to `fatal`, which does an `into()`, which clones the
reference, doing a second allocation. Two allocations for a single
string, bleh.

This commit changes the `From` impls so that you can only create a
`{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static,
str>`. This requires changing all the places that currently create one
from a `&String`. Most of these are of the `&format!(...)` form
described above; each one removes an unnecessary static `&`, plus an
allocation when executed. There are also a few places where the existing
use of `&String` was more reasonable; these now just use `clone()` at
the call site.

As well as making the code nicer and more efficient, this is a step
towards possibly using `Cow<'static, str>` in
`{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing
the `From<&'a str>` impls to `From<&'static str>`, which is doable, but
I'm not yet sure if it's worthwhile.

Use `Cow` in `{D,Subd}iagnosticMessage`.

Each of `{D,Subd}iagnosticMessage::{Str,Eager}` has a comment:
```
// FIXME(davidtwco): can a `Cow<'static, str>` be used here?
```
This commit answers that question in the affirmative. It's not the most
compelling change ever, but it might be worth merging.

This requires changing the `impl<'a> From<&'a str>` impls to `impl
From<&'static str>`, which involves a bunch of knock-on changes that
require/result in call sites being a little more precise about exactly
what kind of string they use to create errors, and not just `&str`. This
will result in fewer unnecessary allocations, though this will not have
any notable perf effects given that these are error paths.

Note that I was lazy within Clippy, using `to_string` in a few places to
preserve the existing string imprecision. I could have used `impl
Into<{D,Subd}iagnosticMessage>` in various places as is done in the
compiler, but that would have required changes to *many* call sites
(mostly changing `&format("...")` to `format!("...")`) which didn't seem
worthwhile.

Don't lint manual_let_else in cases where the question mark operator would work

Also, lint question_mark for `let...else` clauses that can be simplified to use `?`.

Fix the now stricter lint in manual_rem_euclid.rs

Put into one pass

Don't suppress manual_let_else if question_mark is allowed

If question_mark is allowed, there is no overlap any more,
so we can just not suppress it.

Pass correct substs to `implements_trait` in `incorrect_impls`

`Copy<T>` does in fact not exist. The substs on the trait_ref contain
the `Self` type of the impl as the first parameter, so passing that
to `implements_trait`, which then nicely prepends the `Self` type
for us does not end will.

first try at this

rename to `manual_partial_ord_and_ord_impl`

`unimplemented!` and `unreachable!`.

Signed-off-by: Panagiotis Foliadis <[email protected]>

Add "Known problems" section to `needless_borrow` documentation

[`tuple_array_conversions`]: move from `complexity` to `nursery`

Due to outstanding issues:
* rust-lang#11082
* rust-lang#11085
