rust-analyzer doesn't work most of the time on 23.03

[0x00A]

Summary

After updating to 23.03 today, I noticed that rust-analyzer doesn't work with helix most of the time, go-to definition, doc for item under cursor etc. rarely works, then you restart helix or do :lsp-restart and it works or doesn't. This is not the case with 22.12 which I have used daily since it was released. I tested again with the 22.12 and it works as expected each time.

Reproduction Steps

# src/main.rs

fn main() {
    let _ = foo(32);
}

pub fn foo(n: i32) -> i32 {
    n
}

1. hx src/main.rs
2. move to foo
3. <space>k

I expected this to happen:

popup with the relevant info

foo

pub fn foo(n: i32) -> i32

Instead, this happened:

Nothing

Just tried this out on 23.03, no issues. Followed full reproduction steps and the expected result is what I receive. I know this doesnt resolve your issue, but it does seem to be an issue with your environment in some way

I dug a little deeper and I found the following:

cd C:\
cargo new Uppercase
cd Uppercase
hx

rust-analyzer works as expected on both 23.03 and 22.12

However

cd C:\
cargo new Uppercase
cd uppercase  <--- notice the lowercase first character
hx

rust-analyzer only works on 22.12

On windows paths are not case sensitive so Uppercase and uppercase are the same directory.

Accidentally closed.

I have some ideas of what might be causing this. Could just post the logs for the reproduction case in the uppercase directory and the Uppercase directory so I have a direct comparison? My guess is that this is a RA bug

Ah I think we are missing canonicalization in the workspace detection, I will look into a fix.
I think this regressed by #6290 missing to normalize the LSP roots

[pascalkuthe]

If I guessed correctly than #6517 should fix this. Could you test again @0x00A I don't use windows

helix 23.03 (5e75d33) works as expected.
