fix: Don't catch the server activation error
We are are rethrowing and showing errors higher up in the call stack already. This just ate the error hiding the stacktrace unnecessarily.
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
Use Set instead of Vec in transitive_relation
Helps with #103195. It doesn't fix the underlying quadraticness but it makes it _a lot_ faster to an extent where even doubling the amount of nested references still takes less than two seconds (50s on nightly).
I want to see whether this causes regressions (because the vec was usually quite small) or improvements (as lookup for bigger sets is now much faster) in real code.
Handle core dumps output in QEMU user mode
In addition to the whole-system emulation/virtualization, QEMU also supports user-mode emulation, where the emulation happens as a normal process inside the parent system. This allows running most tests by simply spawning remote-test-server inside user-mode emulation.
Unfortunately, QEMU always writes its own message in addition to the system one when a core dump happens, which breaks a few tests which match on the exact output of the system.
This PR changes those tests to strip the (possible) QEMU output before checking if the output is expected.
The illumos linker does not support --strip-debug
When building and testing rust 1.64.0 on illumos, we saw a large number of failing tests associated with:
```
= note: ld: fatal: unrecognized option '--strip-debug'
ld: fatal: use the -z help option for usage information
collect2: error: ld returned 1 exit status
```
The illumos linker does not support the `--strip-debug` option (although it does support `--strip-all`).
Revert "feat: Diagnose some incorrect usages of the question mark operator"
Reverts rust-lang/rust-analyzer#13354
It seems like we are getting stuck with inference variables here, not just placeholders and errors so there is probably more wrong here that I don't understand. Reverting seems like the best solution right now as I don't have the time to look into this this week.
Remove "execute" bit from lock file permissions
Previously, flock would set the "execute" bit on Rust lock files. That makes no sense.
This patch clears the "execute" bit on Rust lock files.
See issue #102531.
Add `Box<[T; N]>: TryFrom<Vec<T>>`
We have `[T; N]: TryFrom<Vec<T>>` (#76310) and `Box<[T; N]>: TryFrom<Box<[T]>>`, but not this combination.
`vec.into_boxed_slice().try_into()` isn't quite a replacement for this, as that'll reallocate unnecessarily in the error case.
**Insta-stable, so needs an FCP**
(I tried to make this work with `, A`, but that's disallowed because of `#[fundamental]` https://github.com/rust-lang/rust/issues/29635#issuecomment-1247598385)
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.
feat: Diagnose some incorrect usages of the question mark operator
Trying to figure out how the type stuff in r-a works some more, I think I am doing this correct here but I am not quite sure :)
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`
