Not the dropping of the trailing `s` -- this type describes a single
diagnostic and its name should be singular.

`ParseSess` cleanups
The main change here is to rename all `ParseSess` values as `psess`. Plus a few other small cleanups.
r? `@wesleywiser`
|
|
Existing names for values of this type are `sess`, `parse_sess`,
`parse_session`, and `ps`. `sess` is particularly annoying because
that's also used for `Session` values, which are often co-located, and
it can be difficult to know which type a value named `sess` refers to.
(That annoyance is the main motivation for this change.) `psess` is nice
and short, which is good for a name used this much.
The commit also renames some `parse_sess_created` values as
`psess_created`.

Suggest moving definition if non-found macro_rules! is defined later

Consider middle segments of paths in `unused_qualifications`
Currently `unused_qualifications` looks at the last segment of a path to see if it can be trimmed, this PR extends the check to the middle segments also
```rust
// currently linted
use std::env::args();
std::env::args(); // Removes `std::env::`
```
```rust
// newly linted
use std::env;
std::env::args(); // Removes `std::`
```
Paths with generics in them are now linted as long as the part being trimmed is before any generic args, e.g. it will now suggest trimming `std::vec::` from `std::vec::Vec<usize>`
Paths with any segments that are from an expansion are no longer linted
Fixes #100979
Fixes #96698

Improve renaming suggestion when item starts with underscore
Fixes https://github.com/rust-lang/rust/issues/121776.
It goes from:
```terminal
error[E0433]: failed to resolve: use of undeclared type `Foo`
--> src/foo.rs:6:13
|
6 | let _ = Foo::Bar;
| ^^^ use of undeclared type `Foo`
|
help: an enum with a similar name exists, consider changing it
|
1 | enum Foo {
| ~~~
```
to:
```terminal
error[E0433]: failed to resolve: use of undeclared type `Foo`
--> foo.rs:6:13
|
6 | let _ = Foo::Bar;
| ^^^ use of undeclared type `Foo`
|
help: an enum with a similar name exists, consider renaming `_Foo` into `Foo`
|
1 | enum Foo {
| ~~~
error: aborting due to 1 previous error
```

obvious what is actually suggested

Diagnostic renaming
Renaming various diagnostic types from `Diagnostic*` to `Diag*`. Part of https://github.com/rust-lang/compiler-team/issues/722. There are more to do but this is enough for one PR.

Fix issues in suggesting importing extern crate paths
Fixes #121168

Much better!
Note that this involves renaming (and updating the value of)
`DIAGNOSTIC_BUILDER` in clippy.
|
|
`Resolver::report_error` always emits (this commit makes that clearer),
so the `span_delayed_bug` is unnecessary.

Add newtypes for bool fields/params/return types
Fixed all the cases of this found with some simple searches for `*/ bool` and `bool /*`; probably many more

This commit undoes some of the previous commit's mechanical changes,
based on human judgment.
|
|
I have a suspicion that quite a few delayed bug paths are impossible to
reach, so I did an experiment.
I converted every `delayed_bug` to a `bug`, ran the full test suite,
then converted back every `bug` that was hit. A surprising number were
never hit.
The next commit will convert some more back, based on human judgment.

resolve: Scale back unloading of speculatively loaded crates
Fixes https://github.com/rust-lang/rust/issues/120830 and fixes https://github.com/rust-lang/rust/issues/120909 while still unblocking https://github.com/rust-lang/rust/pull/117772.
I cannot reproduce https://github.com/parasyte/crash-rustc as an UI test for some reason, but I tested all the cases linked above manually.

There are lots of functions that modify a diagnostic. This can be via a
`&mut Diagnostic` or a `&mut DiagnosticBuilder`, because the latter type
wraps the former and impls `DerefMut`.
This commit converts all the `&mut Diagnostic` occurrences to `&mut
DiagnosticBuilder`. This is a step towards greatly simplifying
`Diagnostic`. Some of the relevant function are made generic, because
they deal with both errors and warnings. No function bodies are changed,
because all the modifier methods are available on both `Diagnostic` and
`DiagnosticBuilder`.

situations like module-relative uses, we can do more accurate redundant import checking.
fixes #117448
For example unnecessary imports in std::prelude that can be eliminated:
```rust
use std::option::Option::Some;//~ WARNING the item `Some` is imported redundantly
use std::option::Option::None; //~ WARNING the item `None` is imported redundantly
```

errors: only eagerly translate subdiagnostics
Subdiagnostics don't need to be lazily translated, they can always be eagerly translated. Eager translation is slightly more complex as we need to have a `DiagCtxt` available to perform the translation, which involves slightly more threading of that context.
This slight increase in complexity should enable later simplifications - like passing `DiagCtxt` into `AddToDiagnostic` and moving Fluent messages into the diagnostic structs rather than having them in separate files (working on that was what led to this change).

Make sure `tcx.create_def` also depends on the forever red node, instead of just `tcx.at(span).create_def`
oversight from https://github.com/rust-lang/rust/pull/119136
Not actually an issue, because all uses of `tcx.create_def` were in the resolver, which is `eval_always`, but still good to harden against future uses of `create_def`

Remove importing suggestions when there is a shadowed typo candidate
Fixes #120559
|

|

`swap` has been deprecated in favour of `swap_remove` - the behaviour
is the same though.

- improve diagnostics of field uniqueness check and representation check
- simplify the implementation of field uniqueness check
- remove some useless codes and improvement neatness

Invert diagnostic lints.
That is, change `diagnostic_outside_of_impl` and `untranslatable_diagnostic` from `allow` to `deny`, because more than half of the compiler has been converted to use translated diagnostics.
This commit removes more `deny` attributes than it adds `allow` attributes, which proves that this change is warranted.

Remove unused args from functions
`#[instrument]` suppresses the unused arguments from a function, *and* suppresses unused methods too! This PR removes things which are only used via `#[instrument]` calls, and fixes some other errors (privacy?) that I will comment inline.
It's possible that some of these arguments were being passed in for the purposes of being instrumented, but I am unconvinced by most of them.

resolve: Unload speculatively resolved crates before freezing cstore
Name resolution sometimes loads additional crates to improve diagnostics (e.g. suggest imports).
Not all of these diagnostics result in errors, sometimes they are just warnings, like in #117772.
If additional crates loaded speculatively stay and gets listed by things like `query crates` then they may produce further errors like duplicated lang items, because lang items from speculatively loaded crates are as good as from non-speculatively loaded crates.
They can probably do things like adding unintended impls from speculatively loaded crates to method resolution as well.
The extra crates will also get into the crate's metadata as legitimate dependencies.
In this PR I remove the speculative crates from cstore when name resolution is finished and cstore is frozen.
This is better than e.g. filtering away speculative crates in `query crates` because things like `DefId`s referring to these crates and leaking to later compilation stages can produce ICEs much easier, allowing to detect them.
The unloading could potentially be skipped if any errors were reported (to allow using `DefId`s from speculatively loaded crates for recovery), but I didn't do it in this PR because I haven't seen such cases of recovery. We can reconsider later if any relevant ICEs are reported.
Unblocks https://github.com/rust-lang/rust/pull/117772.
