macros: simplify field ordering in diag derive

Following the approach taken in earlier commits to separate formatting
initialization from use in the subdiagnostic derive, simplify the

solved this problem.

David Wood [Mon, 3 Oct 2022 13:28:02 +0000 (14:28 +0100)]
macros: separate suggestion fmt'ing and emission

Diagnostic derives have previously had to take special care when
ordering the generated code so that fields were not used after a move.

This is unlikely for most fields because a field is either annotated
with a subdiagnostic attribute and is thus likely a `Span` and copiable,
or is a argument, in which case it is only used once by `set_arg`
anyway.

However, format strings for code in suggestions can result in fields
being used after being moved if not ordered carefully. As a result, the
derive currently puts `set_arg` calls last (just before emission), such
as:

```rust
let diag = { /* create diagnostic */ };

diag.span_suggestion_with_style(
    span,
    fluent::crate::slug,
    format!("{}", __binding_0),
    Applicability::Unknown,
    SuggestionStyle::ShowAlways
);
/* + other subdiagnostic additions */

diag.set_arg("foo", __binding_0);
/* + other `set_arg` calls */

diag.emit();
```

For eager translation, this doesn't work, as the message being
translated eagerly can assume that all arguments are available - so
arguments _must_ be set first.

Format strings for suggestion code are now separated into two parts - an
initialization line that performs the formatting into a variable, and a
usage in the subdiagnostic addition.

By separating these parts, the initialization can happen before
arguments are set, preserving the desired order so that code compiles,
while still enabling arguments to be set before subdiagnostics are
added.

```rust
let diag = { /* create diagnostic */ };

let __code_0 = format!("{}", __binding_0);
/* + other formatting */

diag.set_arg("foo", __binding_0);
/* + other `set_arg` calls */

diag.span_suggestion_with_style(
    span,
    fluent::crate::slug,
    __code_0,
    Applicability::Unknown,
    SuggestionStyle::ShowAlways
);
/* + other subdiagnostic additions */

Uplift `clippy::for_loops_over_fallibles` lint into rustc

This PR, as the title suggests, uplifts [`clippy::for_loops_over_fallibles`] lint into rustc. This lint warns for code like this:
```rust
for _ in Some(1) {}
for _ in Ok::<_, ()>(1) {}
```
i.e. directly iterating over `Option` and `Result` using `for` loop.

There are a number of suggestions that this PR adds (on top of what clippy suggested):
1. If the argument (? is there a better name for that expression) of a `for` loop is a `.next()` call, then we can suggest removing it (or rather replacing with `.by_ref()` to allow iterator being used later)
   ```rust
    for _ in iter.next() {}
    // turns into
    for _ in iter.by_ref() {}
    ```
2. (otherwise) We can suggest using `while let`, this is useful for non-iterator, iterator-like things like [async] channels
   ```rust
   for _ in rx.recv() {}
   // turns into
   while let Some(_) = rx.recv() {}
   ```
3. If the argument type is `Result<impl IntoIterator, _>` and the body has a `Result<_, _>` type, we can suggest using `?`
   ```rust
   for _ in f() {}
   // turns into
   for _ in f()? {}
   ```
4. To preserve the original behavior and clear intent, we can suggest using `if let`
   ```rust
   for _ in f() {}
   // turns into
   if let Some(_) = f() {}
   ```
(P.S. `Some` and `Ok` are interchangeable depending on the type)

I still feel that the lint wording/look is somewhat off, so I'll be happy to hear suggestions (on how to improve suggestions :D)!

Auto merge of #89123 - the8472:push_in_capacity, r=amanieu

add Vec::push_within_capacity - fallible, does not allocate

This method can serve several purposes. It

* is fallible
* guarantees that items in Vec aren't moved
* allows loops that do `reserve` and `push` separately to avoid pulling in the allocation machinery a second time in the `push` part which should make things easier on the optimizer
* eases the path towards `ArrayVec` a bit since - compared to `push()` - there are fewer questions around how it should be implemented

I haven't named it `try_push` because that should probably occupy a middle ground that will still try to reserve and only return an error in the unlikely OOM case.

Reduce CString allocations in std as much as possible

Currently, every operation involving paths in `fs` allocates memory to hold the path before sending it through the syscall. This PR instead uses a stack allocation (chosen size is somewhat arbitrary) when the path is short before falling back to heap allocations for long paths.

Benchmarks show that the stack allocation is ~2x faster for short paths:

```
test sys::unix::fd::tests::bench_heap_path_alloc                  ... bench:          34 ns/iter (+/- 2)
test sys::unix::fd::tests::bench_stack_path_alloc                 ... bench:          15 ns/iter (+/- 1)
```

For long paths, I couldn't find any measurable difference.

---

I'd be surprised if I was the first to think of this, so I didn't fully flush out the PR. If this change is desirable, I'll make use of `run_with_cstr` across all platforms in every fs method (currently just unix open for testing). I also added an `impl From<FromBytesWithNulError>` which is presumably a no-no (or at least needs to be done in another PR).

rustdoc: Document effect of fundamental types

This was implemented in https://github.com/rust-lang/rust/pull/96565, but not documented. But it's a useful feature for everyone who implements own wrapper (especially wrappers-around-pointers) types, so that they can behave like pointers (and stdlib wrappers) do -- so here goes a mention in the unstable section of the rustdoc book.

(That is where I initially looked to find tricks for making my own wrapper types be transparent to documentation).

don't ICE when normalizing closure input tys

We were ICEing while rendering diagnostics because `universe_causes` is expected to track every universe created in the typeck's infcx.

`normalize_and_add_constraints` doesn't update `universe_causes`
when creating new universes, causing an ICE. Remove it!

Add spans to better track normalization constraints.

Fix couple places where `universe_causes` is not updated correctly to
track newly added universes.
