7690: Extract `fn load_workspace(…)` from `fn load_cargo(…)` r=matklad a=regexident
Unfortunately in https://github.com/rust-analyzer/rust-analyzer/pull/7595 I forgot to `pub use` (rather than just `use`) the newly introduced `LoadCargoConfig`.
So this PR fixes this now.
It also:
- splits up `fn load_cargo` into a "workspace loading" and a "project loading" phase
- adds a `progress: &dyn Fn(String)` to allow third-parties to provide CLI progress updates, too
The motivation behind both of these is the fact that rust-analyzer currently does not support caching.
As such any third-party making use of `ra_ap_…` needs to providing a caching layer itself.
Unlike for rust-analyzer itself however a common use-pattern of third-parties is to analyze a specific target (`--lib`/`--bin <BIN>`/…) from a specific package (`--package`). The targets/packages of a crate can be obtained via `ProjectWorkspace::load(…)`, which currently is performed inside of `fn load_cargo`, effectively making the returned `ProjectWorkspace` inaccessible to the outer caller. With this information one can then provide early error handling via CLI (in case of ambiguities or invalid arguments, etc), instead of `fn load_cargo` failing with a possibly obscure error message. It also allows for annotating the persisted caches with its specific associated package/target selector and short-circuit quickly if a matching cache is found on disk, significantly cutting load times.
Before:
```rust
pub struct LoadCargoConfig {
pub cargo_config: &CargoConfig,
pub load_out_dirs_from_check: bool,
pub with_proc_macro: bool,
}
pub fn load_cargo(
root: &Path,
config: &LoadCargoConfig
) -> Result<(AnalysisHost, vfs::Vfs)> {
// ...
}
```
After:
```rust
pub fn load_workspace(
root: &Path,
config: &CargoConfig,
progress: &dyn Fn(String),
) -> Result<ProjectWorkspace> {
// ...
}
pub struct LoadCargoConfig {
pub load_out_dirs_from_check: bool,
pub with_proc_macro: bool,
}
pub fn load_cargo(
ws: ProjectWorkspace,
config: &LoadCargoConfig,
progress: &dyn Fn(String),
) -> Result<(AnalysisHost, vfs::Vfs)> {
// ...
}
```

7643: Automatically detect the rustc-src directory (fixes#3517) r=matklad a=bnjbvr
If the configured rustcSource was not set, then try to automatically
detect a source for the sysroot rustc directory.
I wasn't sure how to do it in the case of the project.json file, though.
7663: Tolerate spaces in nix binary patching r=matklad a=CertainLach
If path to original file contains space (I.e on code insiders, where
default data directory is ~/Code - Insiders/), then there is syntax
error evaluating src arg.
Instead pass path as str, and coerce to path back in nix expression

In some situations we reloaded the workspace in the tests after having reported
to be ready. There's two fixes here:
1. Add a version to the VFS config and include that version in progress reports,
so that we don't think we're done prematurely;
2. Delay status transitions until after changes are applied. Otherwise the last
change during loading can potentially trigger a workspace reload, if it contains
interesting changes.
I've noticed that there are various suggestions that rust-analyzer seems
to filter out, even if they make sense.
Here's an example of where it seems like there should be a suggestion,
but there isn't:
It turns out that this specific suggestion is not considered
`MachineApplicable`, which are the only suggestions that rust-analyzer
accepts. However if you read the documentation for `MachineApplicable`,
b3897e3d13/compiler/rustc_lint_defs/src/lib.rs (L27-L29)
then you realize that these are specifically only those suggestions that
rust-analyzer could even automatically apply (in some distant future,
behind some setting or so). Other suggestions that may have some
semantic impact do not use `MachineApplicable`. So all other suggestions
are still intended to be suggested to the user, just not automatically
applied without the user being consulted.
b3897e3d13/compiler/rustc_lint_defs/src/lib.rs (L22-L24)
So with that in mind, rust-analyzer should almost definitely not filter
out `MaybeIncorrect` (which honestly is named horribly, it just means
that it's a semantic change, not just a syntactical one).
Then there's `HasPlaceholders` which basically is just another semantic
one, but with placeholders. The user will have to make some adjustments,
but the suggestion still is perfectly valid. rust-analyzer could
probably detect those placeholders and put proper "tab through" markers
there for the IDE, but that's not necessary for now.
Then the last one is `Unspecified` which is so unknown that I don't even
know how to judge it, meaning that the suggestion should probably also
just be suggested to the user and then they can decide.
So with all that in mind, I'm proposing to get rid of the check for
Applicability entirely.
7457: Add no-buffering file logging and wait for a debugger option. r=vsrs a=vsrs
Adds two command line flags: `--no-buffering` and `--wait-dbg`.
Not sure if someone else needs this, but personally I found both flags extremely useful trying to figure out why RA does not work with Visual Studio. Or better to say why Visual Studio does not work with RA.
