chore: rename `salsa` to `ra_salsa`
Laying some groundwork to start before I import the new Salsa crate. Here's why:
1. As part of the migration, `@darichey,` `@Wilfred,` and I will create new Salsa equivalents of the existing databases/query groups. We'll get them to compile crate-by-crate.
2. Once we wrote all equivalents of all queries, we'd start to refactor usage sites of the vendored Salsa to use the new Salsa databases.
3. Starting porting usage sites of old Salsa to the new Salsa.
4. Remove the vendored `ra_salsa`; declare victory.

fix: Do not consider mutable usage of deref to `*mut T` as deref_mut
Fixes#15799
We are doing some heuristics for deciding whether the given deref is deref or deref_mut here;
5982d9c420/crates/hir-ty/src/infer/mutability.rs (L182-L200)
But this heuristic is erroneous if we are dereferencing to a mut ptr and normally those cases are filtered out here as builtin;
5982d9c420/crates/hir-ty/src/mir/lower/as_place.rs (L165-L177)
Howerver, this works not so well if the given dereferencing is double dereferencings like the case in the #15799.
```rust
struct WrapPtr(*mut u32);
impl core::ops::Deref for WrapPtr {
type Target = *mut u32;
fn deref(&self) -> &Self::Target {
&self.0
}
}
fn main() {
let mut x = 0u32;
let wrap = WrapPtr(&mut x);
unsafe {
**wrap = 6;
}
}
```
Here are two - outer and inner - dereferences here, and the outer dereference is marked as deref_mut because there is an assignment operation.
And this deref_mut marking is propagated into the inner dereferencing.
In the later MIR lowering, the outer dereference is filtered out as it's expr type is `*mut u32`, but the expr type in the inner dereference is an ADT, so this false-mutablility is not filtered out.
This PR cuts propagation of this false mutablilty chain if the expr type is mut ptr.
Since this happens before the resolve_all, it may have some limitations when the expr type is determined as mut ptr at the very end of inferencing, but I couldn't find simple fix for it 🤔
internal: Don't resolve extern crates in import fix point resolution
The fix point loop won't progress them given the potential extern crate candidates are set up at build time.
fix: Join rustfmt overrideCommand with project root
When providing a custom rustfmt command, join it with the project root instead of the workspace root. This fixes rust-analyzer getting the wrong invocation path in projects containing subprojects.
This makes the behaviour consistent with how a custom path provided in rust-analyzer.procMacro.server behaves already.

feat: Highlight exit points of async blocks
Async blocks act similar to async functions in that the await keywords are related, but also act like functions where the exit points are related.
Fixes#18147
fix: include description in label details when detail field is marked for …
Fixes https://github.com/rust-lang/rust-analyzer/issues/18231.
When omitting the autocomplete detail field, the autocomplete label details can still be returned. Currently the label details are missing the description field if the detail field is included in resolveSupport since it is being overwritten as None and opted to be sent with `completionItem/resolve`.
Example completion capabilities.
```
completion = {
completionItem = {
commitCharactersSupport = true,
deprecatedSupport = true,
documentationFormat = { "markdown", "plaintext" },
insertReplaceSupport = true,
insertTextModeSupport = {
valueSet = { 1, 2 }
},
labelDetailsSupport = true,
preselectSupport = true,
resolveSupport = {
properties = { "documentation", "detail", "additionalTextEdits", "sortText", "filterText", "insertText", "textEdit", "insertTextFormat", "insertTextMode" }
},
snippetSupport = true,
tagSupport = {
valueSet = { 1 }
}
}
```
lsp: fix completion_item something_to_resolve not being a latch to true
while looking at #18245 i noticed that `something_to_resolve` could technically flap between true -> false if some subsequent fields that were requested to be resolved were empty.
this fixes that by using `|=` instead of `=` when assigning to `something_to_resolve` which will prevent it from going back to false once set.
although some cases it's simply assigning to `true` i opted to continue to use `|=` there for uniformity sake. but happy to change those back to `=`'s.
cc `@SomeoneToIgnore`
before, when formatting struct constructor for `struct S(usize, usize)` it would format as:
extern "rust-call" S(usize, usize) -> S
but after this change, we'll format as:
fn S(usize, usize) -> S

Resolves issue #18222
fix: Fix resolution of label inside macro
When working on Something Else (TM) (I left a hint in the commits :P), I noticed to my surprise that labels inside macros are not resolved. This led to a discovery of *two* unrelated bugs, which are hereby fixed in two commits.
This fixes a bug where labels inside macros were not resolved, but more importantly this prepares us to a future where we have hygiene, and textual equivalence isn't enough to resolve identifiers.
internal: Send less data during `textDocument/completion` if possible
Similar to https://github.com/rust-lang/rust-analyzer/pull/15522, stops sending extra data during `textDocument/completion` if that data was set in the client completions resolve capabilities, and sends those only during `completionItem/resolve` requests.
Currently, rust-analyzer sends back all fields (including potentially huge docs) for every completion item which might get large.
Same as the other one, this PR aims to keep the changes minimal and does not remove extra computations for such fields — instead, it just filters them out before sending to the client.
The PR omits primitive, boolean and integer, types such as `deprecated`, `preselect`, `insertTextFormat`, `insertTextMode`, etc. AND `additionalTextEdits` — this one looks very dangerous to compute for each completion item (as the spec says we ought to if there's no corresponding resolve capabilities provided) due to the diff computations and the fact that this code had been in the resolution for some time.
It would be good to resolve this lazily too, please let me know if it's ok to do.
When tested with Zed which only defines `documentation` and `additionalTextEdits` in its client completion resolve capabilities, rust-analyzer starts to send almost 3 times less characters:
Request:
```json
{"jsonrpc":"2.0","id":104,"method":"textDocument/completion","params":{"textDocument":{"uri":"file:///Users/someonetoignore/work/rust-analyzer/crates/ide/src/inlay_hints.rs"},"position":{"line":90,"character":14},"context":{"triggerKind":1}}}

fix: Ambiguity with CamelCase diagnostic messages, align with rustc warnings
Fixed diagnostic messages so they say UpperCamelCase rather than CamelCase, as it is ambiguous.
Usually I'd call it PascalCase, but in the code base it is called UpperCamelCase so I left it with that naming choice.
`rustc` says `upper camel case` also when the case is wrong
```
warning: trait `testThing` should have an upper camel case name
--> src/main.rs:5:7
|
5 | trait testThing {
| ^^^^^^^^^ help: convert the identifier to upper camel case: `TestThing`
|
= note: `#[warn(non_camel_case_types)]` on by default
```
This is in line with the UPPER_SNAKE_CASE diagnostic messages.
546339a7be/crates/hir-ty/src/diagnostics/decl_check.rs (L60)546339a7be/crates/ide-diagnostics/src/handlers/incorrect_case.rs (L535)
This will mean users opting to not activate `cfg(test)` will lose IDE experience on them, which is quite unfortunate, but this is unavoidable if we want to avoid false positives on e.g. diagnostics. The real fix is to provide IDE experience even for cfg'ed out code, but this is out of scope for this PR.
Rename object_safety
First PR here (yay!), so I read some of the getting started docs. There are a couple references to `handlers.rs`, which as far as I can tell has been refactored into `handlers/*.rs`. I made some tweaks to that in one commit. There is one fixme about a function called `to_lsp_runnable`, which I can't find anywhere at all. I can update that if I get some more info there.
Otherwise I changed references to object safety, is object safe, etc., trying to match case/style as I went. There was one case I found where there's a trait from somewhere else called `is_object_safe`, which I found defined in my cargo registry. I didn't touch that for now, just marked it with a fixme
