Don't show runnable code lenses in libraries outside of the workspace
Addresses #13664. For now I'm just disabling runnable code lenses since the ones that display the number of references and implementations do work correctly with external code.
Also made a tiny TypeScript change to use the typed `sendNotification` overload.
Mega-sync from `rust-lang/rust`
This essentially implements `@oli-obk's` suggestion here https://github.com/rust-lang/rust-analyzer/pull/13459#issuecomment-1297285607, with `@eddyb's` help.
This PR is equivalent to 14 syncs (back and forth) between `rust-lang/rust` and `rust-lang/rust-analyzer`.
Working from this list (from bottom to top):
```
(x) a2a1d9954⬆️ rust-analyzer
(x) 79923c382⬆️ rust-analyzer
(x) c60b1f641⬆️ rust-analyzer
(x) 8807fc4cc⬆️ rust-analyzer

(x) 8231fee46⬆️ rust-analyzer
(x) 22c8c9c40⬆️ rust-analyzer
(x) 9d2cb42a4⬆️ rust-analyzer
```
(This listed was assembled by doing a `git subtree push`, which made a branch, and looking at the new commits in that branch, picking only those that were `⬆️ rust-analyzer` commits)
We used the following commands to simulate merges in both directions:
```shell
TO_MERGE=22c8c9c40 # taken from the list above, bottom to top
git merge --no-edit --no-ff $TO_MERGE
git merge --no-edit --no-ff $(git -C ../rust log --pretty=format:'%cN | %s | %ad => %P' | rg -m1 -F "$(git show --no-patch --pretty=format:%ad $TO_MERGE)" | tee /dev/stderr | rg '.* => \S+ (\S+)$' --replace '$1')
```
We encountered no merge conflicts that Git wasn't able to solve by doing it this way.
Here's what the commit graph looks like (as shown in the Git Lens VSCode extension):

This PR closes#13459
## Does this unbreak `rust->ra` syncs?
Yes, here's how we tried:
In `rust-analyzer`:
* check out `subtree-fix` (this PR's branch)
* make a new branch off of it: `git checkout -b subtree-fix-merge-test`
* simulate this PR getting merged with `git merge master`
In `rust`:
* pull latest master
* make a new branch: `git checkout -b test-change`
* mess with rust-analyzer (I added a comment to `src/tools/rust-analyzer/Cargo.toml`)
* commit
* run `git subtree push -P src/tools/rust-analyzer ra-local final-sync` (this follows the [Clippy sync guide](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/sync.html))
This created a `final-sync` branch in `rust-analyzer`.
In `rust-analyzer`:
* `git merge --no-ff final-sync` (this follows the [Clippy sync guide](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/sync.html))
Now `git log` in `rust-analyzer` shows this:
```

And `git diff 0513fc02a08ea9de952983624bd0a00e98044b36` shows this:

## Does this unbreak `ra->rust` syncs?
Yes, here's how we tried.
From `rust`:
* `git checkout -b sync-from-ra`
* `git subtree pull -P src/tools/rust-analyzer ra-local subtree-fix-merge-test` (this is adapted from the [Clippy sync guide](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/sync.html#performing-the-sync-from-clippy-to-rust-langrust), you would normally use `ra-upstream master` but we're simulating things here)
A commit editor pops up, there was no merge conflicts.
## How do we prevent this from happening again?
Like `@bjorn3` said in https://github.com/rust-lang/rust-analyzer/pull/13459#issuecomment-1293587848
> Whenever syncing from rust-analyzer -> rust you have to immediately sync the merge commit from rust -> rust-analyzer to prevent merge conflicts in the future.
But if we get it wrong again, at least now we have a not-so-painful way to fix it.
Fix: Handle empty `checkOnSave/target` values
This fixes a regression introduced by #13290, in which failing to set `checkOnSave/target` (or `checkOnSave/targets`) would lead to an invalid config.
[Fixes#13660]
Support multiple targets for checkOnSave (in conjunction with cargo 1.64.0+)
This PR adds support for the ability to pass multiple `--target` flags when using
`cargo` 1.64.0+.
## Questions
I needed to change the type of two configurations options, but I did not plurialize the names to
avoid too much churn, should I ?

scip: Generate symbols for local crates.
Consider something like:
```
// a.rs
pub struct Foo { .. } // Foo is "local 1"
fn something() {
crate:🅱️:Bar::new() // Bar is "local 1", but of "b.rs"
}
// b.rs
pub struct Bar { .. } // "local 1"
```
Without this there's no way to disambiguate whether "local 1" references "Bar" or "Foo".
feat: add config for inserting must_use in `generate_enum_as_method`
Should fix#13312
Didn't add a test because I was not sure on how to add test for a specific configuration option, tried to look for the usages for other `AssistConfig` variants but couldn't find any in `tests`. If there is a way to test this, do point me towards it.
I tried to extract the formatting string as a common `template_string` and only have if-else for that, but it didn't compile :(
Also it seems these tests are failing:
```
test config::tests::generate_config_documentation ... FAILED
test config::tests::generate_package_json_config ... FAILED
```
Can you also point me to how to correct these 😅 ( I guess there is some command to automatically generate these? )
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.
Since I searched sources for " a a " sequences,
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.
Fixes#9589

There are also some other typos in the function names, variable names, and file

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: Only flycheck workspace that belongs to saved file
Supercedes https://github.com/rust-lang/rust-analyzer/pull/11038
