Implement invocation strategy config
Fixes https://github.com/rust-lang/rust-analyzer/issues/10793
This allows to change how we run build scripts (and `checkOnSave`), exposing two configs:
- `once`: run the specified command once in the project root (the working dir of the server)
- `per_workspace`: run the specified command per workspace in the corresponding workspace
This also applies to `checkOnSave` likewise, though `once_in_root` is useless there currently, due to https://github.com/rust-lang/cargo/issues/11007
The reason for that was that we were calculating the crate defmaps
of the file we are saving by accident causing us to get stuck waiting
on their expensive computation, while we only need the relevant crate
id.
The main change here should be that flags are not inhereted, so
$ rust-analyzer analysis-stats . -v -v
would do what it should do
We also no longer Don\'t
This fixes a typo first appearing in #94624
in which test-macro diagnostic uses "a" article twice.

I also fixed the same issue in a few source files where I found it.

Amalgamate file changes for the same file ids in process_changes
When receiving multiple change events for a single file id where the last change is a delete the server panics, as it tries to access the file contents of a deleted file. This occurs due to the VFS changes and the in memory file contents being updated immediately, while `process_changes` processes the events afterwards in sequence which no longer works as it will only observe the final file contents. By folding these events together, we will no longer try to process these intermediate changes, as they aren't relevant anyways.

proc-macro ABI breakage still affects the tests when a new stable version
releases. Ideally we'd still be able to run the tests on the rust-analyzer
repo without having to update the proc-macro ABI, but for now just to
unblock CI we will ignore them here, as they are still run in upstream.
Add a new configuration settings to set env vars when running cargo, rustc, etc. commands: cargo.extraEnv and checkOnSave.extraEnv
It can be extremely useful to be able to set environment variables when rust-analyzer is running various cargo or rustc commands (such as `cargo check`, `cargo --print cfg` or `cargo metadata`): users may want to set custom `RUSTFLAGS`, change `PATH` to use a custom toolchain or set a different `CARGO_HOME`.
There is the existing `server.extraEnv` setting that allows env vars to be set when the rust-analyzer server is launched, but using this as the recommended mechanism to also configure cargo/rust has some drawbacks:
- It convolutes configuring the rust-analyzer server with configuring cargo/rustc (one may want to change the `PATH` for cargo/rustc without affecting the rust-analyzer server).
- The name `server.extraEnv` doesn't indicate that cargo/rustc will be affected but renaming it to `cargo.extraEnv` doesn't indicate that the rust-analyzer server would be affected.
- To make the setting useful, it needs to be dynamically reloaded without requiring that the entire extension is reloaded. It might be possible to do this, but it would require the client communicating to the server what the overwritten env vars were at first launch, which isn't easy to do.
This change adds two new configuration settings: `cargo.extraEnv` and `checkOnSave.extraEnv` that can be used to change the environment for the rust-analyzer server after launch (thus affecting any process that rust-analyzer invokes) and the `cargo check` command respectively. `cargo.extraEnv` supports dynamic changes by keeping track of the pre-change values of environment variables, thus it can undo changes made previously before applying the new configuration (and then requesting a workspace reload).
Allow configuration of annotation location.
I've added the ability to configure where lens annotations render relevant to the item they describe. Previously, these would render directly above the line the item is declared on. Now, there is the ability to render these annotations above the entire item (including doc comments, and attributes).
The names of the config options are up for debate, I did what seemed best to me but if anyone has better ideas let me know.
This is my first contribution so if I've missed anything please let me know.
Here's a preview of what the new option looks like:

Restructure `find_path` into a separate functions for modules and non-module items
Follow up to https://github.com/rust-lang/rust-analyzer/pull/13212
Also renames `prefer_core` imports config to `prefer_no_std` and changes the behavior of no_std path searching by preferring `core` paths `over` alloc
This PR turned into a slight rewrite, so it unfortunately does a few more things that I initially planned to (including a bug fix for enum variant paths)
Previously, annotations would only appear above the name of an item (function signature, struct declaration, etc).
Now, rust-analyzer can be configured to show annotations either above the name or above the whole item (including doc comments and attributes).
Make use of NoHash hashing for FileId and CrateId
Both of these are mere integers so there is nothing to hash here.
Ideally we would use this for `la_arena::Idx` too, but that doesn't work due to the orphan rule, and `la_arena` is unfortunately a public library so we can't really do much here... Unless we remove the trait restriction but I'd like not to
feat: Run test mod from anywhere in parent file
The "Run" feature of rust-analyzer is super useful, especially for running
individual tests or test-modules during development.
One common pattern in rust development is to develop tests in the same file as
production code, inside a module (usually called `test` or `tests`) marked with
`#[cfg(test)]`. Unforunately, this pattern is not well supported by r-a today,
as a test module won't show up as a runnable unless the cursor is inside it.
In my experience, it is quite common to want to run the tests associated with
some production code immediately after editing it, not only after editing the
tests themselves. As such it would be better if test modules were available
from the "Run" menu even when the cursor is outside the test module.
This change updates the filtration logic for runnables in
`handlers::handle_runnables` to special case `RunnableKind::TestMod`, making
test modules available regardless of the cursor location. Other `RunnableKind`s
are unnaffected.

rust-analyzer's RUSTC_WRAPPER unconditionally succeeds `cargo check`
invocations tripping up build scripts using `cargo check` to probe for
successful compilations. To prevent this from happening the RUSTC_WRAPPER
now checks if it's run from a build script by looking for the
`CARGO_CFG_TARGET_ARCH` env var that cargo sets only when running build
scripts.
When r-a starts up, it starts switching the workspace before all vfs
events have been processed which causes us to switch workspace multiple
times until all vfs changes have been processed. This scales with the
size of the project and its dependencies. If workspace files from
dependencies as well as the sysroot get loaded, we shouldn't switch
the workspace as those have no impact on the project workspace.

feat: Spawn a proc-macro-srv instance per workspace
cc https://github.com/rust-lang/rust-analyzer/issues/12855
The idea is to have each server be spawned with the appropriate toolchain, that way workspaces with differing toolchains shouldn't suffer from proc-macro abi mismatches.
Rationale: Merge commits will probably end up in
`rust-lang/rust-analyzer` when doing "rust=>ra" syncs anyway.
It could be changed to only check for merge commits in non-sync PRs,
but it's "probably not worth the hassle"
This adds an `in-rust-tree` feature that will be enabled when
rust-analyzer is built from `rust-lang/rust`. Due to the way
"git subtree" works, that test _will_ find merge commits and
fail, so we simply skip it.
Add simple support for completion item details
Supercedes https://github.com/rust-lang/rust-analyzer/pull/9891
This doesn't yet really implement anything new, it just adds the scaffolding for the protocol conversion
fix: make file watcher config a drop-down (and clarify the options)
Fixes https://github.com/rust-lang/rust-analyzer/issues/12794
Also renames "notify" to "server", since that's clearer ("notify" is still accepted for compatibility).
fix: Pass the build data to rustc_private crates
With this all proc-macros should resolve in rustc now when setting up the build script running command properly.

feat: hide type inlay hints for initializations of closures

This PR adds an option to hide the inlay hints for `let IDENT_PAT = CLOSURE_EXPR;`, which is a somewhat common coding pattern. Currently the inlay hints for the assigned variable and the closure expression itself are both displayed, making it rather repetitive.
In order to be consistent with closure return type hints, only closures with block bodies will be hid by this option.
Personally I'd feel comfortable making it always enabled (or at least when closure return type hints are enabled), but considering the precedent set in #10761, I introduced an off-by-default option for this.

Config revamp
Fixes https://github.com/rust-lang/rust-analyzer/issues/11790
Fixes https://github.com/rust-lang/rust-analyzer/issues/12115
This PR changes a lot of config names, and a few ones are being merged or split apart. The reason for this is that our configuration names currently are rather inconsistent and some where poorly chosen in regards to extensability. This PR plans to fix that.
We still allow the old config names by patching them to the new ones before deserializing to keep backwards compatability with other clients (the VSCode client will auto update the config) but ideally we will get rid of that layer in the future.
Here is a list of the changes:
These are simple renames `old_name | alias1 | alias2 ... -> new_name` (the vscode client will fix these up automagically):

10802: Allow clients to configure the global workspace search limit r=Veykril a=knutwalker
Playing around with [helix](https://helix-editor.com) I realized that the global worksapce symbol search works different compared to vs-code.
Helix requires all possible symbols in one query and does no subsequent refinement searched.
This PR adds a configuration option to override the default search limit with the default being the currently hardocded value.
Helix users can increment this limit for their instance with a config like
```toml
[[language]]
name = "rust"
language-server = { command = "rust-analyzer" }
[language.config]
workspace = { symbol = { search = { limit = 65536 }}}

11866: fix: Prevent underflow in range conversion r=Veykril a=skyfmmf
Previously, when line numbers of Rust spans were converted to LSP ranges, they could underflow resulting in very large line numbers. As an underflow is always wrong, prevent it and use 0 instead.
This was noticed when opening an empty file in `src/bin/` of a library crate. In this case rustc produces a span with `"line_start": 0, "line_end": 0` resulting in the underflow.

11182: fix: don't panic on seeing an unexpected offset r=Veykril a=dimbleby
Intended as a fix, or at least a sticking plaster, for #11081.
I have arranged that [offset()](1ba9a924d7/crates/ide_db/src/line_index.rs (L105-L107)) returns `Option<TextSize>` instead of going out of bounds; other changes are the result of following the compiler after doing this.
Perhaps there's still an issue here - I suppose the server and client have gotten out of sync and that probably shouldn't happen in the first place? I see that https://github.com/rust-analyzer/rust-analyzer/issues/10138#issuecomment-913727554 suggests what sounds like a more substantial fix which I think might be aimed in this direction. So perhaps that one should be left open to cover such things?
Meanwhile, I hope that not-crashing is a good improvement: and I can confirm that it works out just fine in the repro I have at #11081.

The direct reason for this is to fix CI on windows, which seems to fail
for some reason after we fixed the watcher-selection logic which (I
think) changed the tests behavior to use notify rather than client.
But this patch seems to make sense in general -- file watching is
notoriously finicky, so controlling it explicitly leads to less fragile
tests.
10902: Handle multiple cargo check quick fix spans r=Veykril a=brandondong
Resolves https://github.com/rust-analyzer/rust-analyzer/issues/10705.
**Cause:**
- For a cargo check diagnostic with multiple spans, only a single quick fix action would be created at the location of `spans[0]`. Additionally, the hover window details would only show the location of `spans[0]` next to the message.
**Fix:**
- Allow cargo check quick fix actions to be triggerable from multiple selection ranges. Specifically, if the selection intersects with any of the replacement spans, the quick fix action is shown.
- No change in behavior for the hover window details. It's pretty minor and I think showing multiple locations next to the message may be more confusing anyways.

With this patch, in these examples
```rust
fn main() {
"⊞$0";
}
```
```rust
struct S {
д$0 u8
}
```
entering ':' character in `$0` places shouldn't cause panics.
The generated code with `()` doesn't compile in most of the cases. To signal
the developer there's something to do, fill in `todo!()`.
Because the file *missing_fields.rs* contains the string `todo!()` it needs
an exception for the test *check_todo*.
When dealing with proc macros, there are two very different kinds of
errors:
* first, usual errors of "proc macro panicked on this particular input"
* second, the proc macro server might day if the user, eg, kills it
First kind of errors are expected and are a normal output, while the
second kind are genuine IO-errors.
For this reason, we use a curious nested result here: `Result<Result<T,
E1>, E2>` pattern, which is 100% inspired by http://sled.rs/errors.html
closes#9922
Turned out to be trivial after preliminary refactor.
The intended behavior is that we schedule cache priming once ws become

typing into a file).

It's good that rust-analyzer doesn't belly-up on a panic in some random
assist.
It is less good that rust-analyzer devs only know that the assists are
buggy when they are actively looking at the logs.
I don't think there's anything wrong with project_model depending on
proc_macro_api directly -- fundamentally, both are about gluing our pure
data model to the messy outside world.
However, it's easy enough to avoid the dependency, so why not.
As an additional consideration, `proc_macro_api` now pulls in `base_db`.
project_model should definitely not depend on that!
cargo llvm-lines shows that path_to_error bloats the code. I don't think
I've needed this functionality recently, seems that we've fixed most of
the serialization problems. So let's just remove it. Should be easy to
add back if we ever need it, and it does make sense to keep the

From the dawn of time, when dinosaurs roamed the and we didn't have
hierarchical profiling, there was the `latest_requests` infra we used to
track the time of ten last requests.
Today, no one is actually using it and, what's more, it itself became
pretty useless -- LSP grew way more chatty, and 10 requests don't really
paint any kind of picture.
Personally, it's been years since I last looked at latest requests in
the status output.
So, let's remove a tiny bit of state from the big ball of complexity
that is `GlobalState` and `main_loop`!
We generally avoid "syntax only" helper wrappers, which don't do much:
they make code easier to write, but harder to read. They also make
investigations harder, as "find_usages" needs to be invoked both for the
wrapped and unwrapped APIs
9734: semantic highlighting: add reference hlmod r=matklad a=jhgg
This PR adds the "reference" highlight modifier!
I basically went around and looked for `HlMod::Mutable` to find the callsites to add a reference. I think these all make sense!

Some features of rust-analyzer requires support for custom commands on
the client side. Specifically, hover & code lens need this.
Stock LSP doesn't have a way for the server to know which client-side
commands are available. For that reason, we historically were just
sending the commands, not worrying whether the client supports then or
not.
That's not really great though, so in this PR we add infrastructure for
the client to explicitly opt-into custom commands, via `extensions`
field of the ClientCapabilities.
To preserve backwards compatability, if the client doesn't set the
field, we assume that it does support all custom commands. In the
future, we'll start treating that case as if the client doesn't support
commands.
So, if you maintain a rust-analyzer client and implement
`rust-analyzer/runSingle` and such, please also advertise this via a
capability.
9693: feat: Add the Hover Range capability which enables showing the type of an expression r=matklad a=alexfertel
Closes https://github.com/rust-analyzer/rust-analyzer/issues/389
This PR extends the `textDocument/hover` method to allow getting the type of an expression. It looks like this:

Edit: One thing I noticed is that when hovering a selection that includes a macro it doesn't work, so maybe this would need a follow-up issue discussing what problem that may have.
(PS: What a great project! I am learning a lot! 🚀)

9558: Do not erase Cargo diagnostics from the closed documents r=matklad a=SomeoneToIgnore
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/6850
The LSP specification at https://microsoft.github.io/language-server-protocol/specifications/specification-3-14/#textDocument_publishDiagnostics states that
> Diagnostics notification are sent from the server to the client to signal results of validation runs.
>
> Diagnostics are “owned” by the server so it is the server’s responsibility to clear them if necessary. The following rule is used for VS Code servers that generate diagnostics:
>
> * if a language is single file only (for example HTML) then diagnostics are cleared by the server when the file is closed.
> * if a language has a project system (for example C#) diagnostics are not cleared when a file closes. When a project is opened all diagnostics for all files are recomputed (or read from a cache).
>
> When a file changes it is the server’s responsibility to re-compute diagnostics and push them to the client. If the computed set is empty it has to push the empty array to clear former diagnostics. Newly pushed diagnostics always replace previously pushed diagnostics. There is no merging that happens on the client side.
So for projects we should not clear any diagnostics from cargo/json projects.
Our "standalone file" mode is in a way a project too, with sysroot attached and a potential support for dynamic standalone files.

9634: minor update to excludeDirs doc r=lnicola a=dae
I saw reference to globs in #7755, but it doesn't look like they're
actually supported, and I had to dig through the source to discover
that the folders are relative to the workspace root. Further digging
was required to get VS Code from hanging for long periods trying to
watch giant Bazel folders that had already been excluded from Rust
Analyzer. Hopefully this tweak will save others the confusion :-)
