VSCode extension stopped working

[alucryd]

rust-analyzer version: (eg. output of "rust-analyzer: Show RA Version" command, accessible in VSCode via Ctrl/⌘+Shift+P)

0.3.1524-standalone

rustc version: (eg. output of rustc -V)

1.69.0 (84c898d65 2023-04-16)

relevant settings: (eg. client settings, or environment variables like CARGO, RUSTC, RUSTUP_HOME or CARGO_HOME)

No special settings, everything is default.

I've been using the extension for a long time, however it recently stopped working on all my machines. Completely resetting VSCode to factory and reinstalling the extension doesn't help. It is loaded and indexes the workspace correctly, but none of the IDE features are available, autocompletion, formatting, refactoring, nothing works.

Running VSCode 1.78.2 on Arch Linux.

Does it work in another project? Do you have anything in the logs?

[alucryd]

Nothing in the logs unfortunately. But I think I found the issue, I have several rust projects in my workspace, it seems the extension is stuck the very first alphabetically, even when I'm working on a file from another one down the list. Deleting all projects but the current one restores functionnality.

[lnicola]

Does that one work if you open it by itself?

[alucryd]

Yes it does.

[alucryd]

Seems to be reproducible, if I try to add another project to the workspace, the second one doesn't work. It starts working only if I delete the first one.

[blu-dev]

Running into a similar issue, it doesn't appear to be the exact same as this one, or at least I cannot reproduce the alphabetical ordering thing locally.

Have tested on both latest stable and latest pre-release, as well as VS Code versions 1.78.0 and 1.78.2 on Ubuntu 22.04. My project is a workspace with 28 crates inside of it.

The output from the Rust Analyzer Language Server produces this every time I open a file:

rustc version: rustc 1.71.0-nightly (1a5f8bce7 2023-05-26)

EDIT: As for behavior, I'm able to do things like symbol renaming, Format on Save is working as expected, auto-complete, etc. Errors are inconsistently reported, and when they are reported 90% of the time they don't go away once the error is corrected

Persisting Error

(Note that the file is saved) 

It seems that it only reports syntax errors as well, as I currently have a lifetime error in one of my signatures and it is not reflected in RA:

Missing Error

The error as reported by `cargo check -p attribute-editor` ``` error: lifetime may not live long enough --> crates/tooling/attribute-editor/src/lib.rs:47:9 | 44 | &mut self, | - let's call the lifetime of this reference `'1` 45 | args: as AttributeBuilder>::Args, | ---- has type `<>::Builder<'2> as AttributeBuilder>::Args` 46 | ) -> AttributeBuilderWrapper<'_, A::Builder<'_>, T> { 47 | / AttributeBuilderWrapper { 48 | | section: self, 49 | | builder: Some( as AttributeBuilder>::from_args(args)), 50 | | } | |_________^ method was supposed to return data with lifetime `'2` but it is returning data with lifetime `'1` error: lifetime may not live long enough --> crates/tooling/attribute-editor/src/lib.rs:47:9 | 44 | &mut self, | - let's call the lifetime of this reference `'1` 45 | args: as AttributeBuilder>::Args, | ---- has type `<>::Builder<'2> as AttributeBuilder>::Args` 46 | ) -> AttributeBuilderWrapper<'_, A::Builder<'_>, T> { 47 | / AttributeBuilderWrapper { 48 | | section: self, 49 | | builder: Some( as AttributeBuilder>::from_args(args)), 50 | | } | |_________^ method was supposed to return data with lifetime `'1` but it is returning data with lifetime `'2` ``` In-editor 

Update, I messed around with it this morning, after a rustup update + cargo update everything seems to be running fine again. Not sure what happened, or if it was my own fault, but you can count me out of this discussion, sorry!

@alucryd does this still happen? Can you prepare a workspace showing the issue?

Had the issue not too long ago still, I can only have one working rust project in a single workspace.
