Implement builtin#format_args, using rustc's format_args parser
`format_args!` now expands to `builtin#format_args(template, args...)`, the actual expansion now instead happens in lowering where we desugar this expression by using lang paths.
As a bonus, we no longer need to evaluate `format_args` as an eager macro which means less macro expansions overall -> less cache thrashing!

internal: unpin serde
Serde no longer uses blobs as of
https://github.com/serde-rs/serde/pull/2590
As such, there's no longer need for us to pin it.
Note that this doesn't upgrade serde version we use: I am fairly confident that the blobs are already there are fine, and now I am fairly confident that all future versions of serde will be fine as well.

serde 1.0.172 and up rely on opaque non-reproducible binary blobs to
function, explicitly not providing a library-level opt-out.
This is problematic for two reasons:
- directly, unauditable binary blobs are a security issue.
- indirectly, it becomes much harder to predict future behaviors of the
crate.
As such, I am willing to go on a limb here and forbid building
rust-analyzer with those versions of serde. Normally, my philosophy is
to defer the choice to the end user, but it's also a design constraint
of rust-analyzer that we don't run random binaries downloaded from the
internet without explicit user's concent.
Concretely, this upper-bounds serde for both rust-analyzer workspace, as
well as the lsp-server lib.
See https://github.com/serde-rs/serde/issues/2538 for wider context.
Map our diagnostics to rustc and clippy's ones
And control their severity by lint attributes `#[allow]`, `#[deny]` and ... .
It doesn't work with proc macros and I would like to fix that before merge but I don't know how to do it.
Split out project loading capabilities from rust-analyzer crate
External tools currently depend on the entire lsp infra for no good reason so let's lift that out so those tools have something better to depend on
- replace tokio's env-filter with a smaller&simpler targets filter
- reshuffle logging infra a bit to make sure there's only a single place
where we read environmental variables
- use anyhow::Result in rust-analyzer binary
This code replaces the thread pool implementation we were using
previously (from the `threadpool` crate). By making the thread pool
aware of QoS, each job spawned on the thread pool can have a different
QoS class.
This commit also replaces every QoS class used previously with Default
as a temporary measure so that each usage can be chosen deliberately.
Drop support for non-syroot proc macro ABIs
This makes some bigger changes to how we handle the proc-macro-srv things, for one it is now an empty crate if built without the `sysroot-abi` feature, this simplifies some things dropping the need to put the feature cfg in various places. The cli wrapper now actually depends on the server, instead of being part of the server that is just exported, that way we can have a true dummy server that just errors on each request if no sysroot support was specified.
With #13552 the depencency of on the command-group crate was introduced, which also
introduced a dependency on nix. That version of nix does not build on Haiku. This
change introduces a newer version of command-group, which also updates nix from
0.22.3 to 0.26.1, which is compatible on Haiku.
feat: Package Windows release artifacts as ZIP and add symbols file
Closes#13872Closes#7747
CC #10371
This allows us to ship a format that's easier to handle on Windows. As a bonus, we can also include the PDB, to get useful stack traces. Unfortunately, it adds a couple of dependencies to `xtask`, increasing the debug build times from 1.28 to 1.58 s (release from 1.60s to 2.20s) on my system.
Compute data layout of types
cc #4091
Things that aren't working:
* Closures
* Generators (so no support for `Future` I think)
* Opaque types
* Type alias and associated types which may need normalization
Things that show wrong result:
* ~Enums with explicit discriminant~
* SIMD types
* ~`NonZero*` and similar standard library items which control layout with special attributes~
At the user level, I didn't put much work, since I wasn't confident about what is the best way to present this information. Currently it shows size and align for ADTs, and size, align, offset for struct fields, in the hover, similar to clangd. I used it some days and I feel I liked it, but we may consider it too noisy and move it to an assist or command.
Bump chalk
There's a bug in current chalk that prevents us from properly supporting GATs, which is supposed to be fixed in v0.86. Note the following:
- v0.86 is only going to be released next Sunday so I'll keep this PR as draft until then.
- This doesn't compile without https://github.com/rust-lang/chalk/pull/779, which I hope will be included in v0.86. I confirmed this compiles with it locally.
Two breaking changes from v0.84:
- `TypeFolder` has been split into `TypeFolder` and `FallibleTypeFolder` (https://github.com/rust-lang/chalk/pull/772)
- `ProjectionTy::self_type_parameter()` has been removed (https://github.com/rust-lang/chalk/pull/778)
Two breaking changes:
- `TypeFolder` has been split into `TypeFolder` and `FallibleTypeFolder`
- `ProjectionTy::self_type_parameter()` has been removed
The main change here should be that flags are not inhereted, so
$ rust-analyzer analysis-stats . -v -v
would do what it should do

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).
