stuck at "Building CrateGraph" in rust-lang/rust repo

[lukas-code]

I'm trying to use the latest pre-release of RA in the https://github.com/rust-lang/rust repo, but it gets stuck at "Building CrateGraph". Autocomplete and go to definition are not working.

It also seems to build up infinite memory usage if you leave it running in the background.

How to reproduce

git clone https://github.com/rust-lang/rust --depth=1
cd rust
./x setup compiler
./x setup vscode # say yes to prompt
./x c # to fetch submodules
code .
# try to use any RA feature

version with regression: rust-analyzer version: 0.4.1888-standalone (6fce1d71d 2024-03-19)

last working version: rust-analyzer version: 0.4.1887-standalone (b91697de8 2024-03-19)

host platform: x86_64-unknown-linux-gnu

[lukas-code]

Looking at b91697d...6fce1d7, it's probably caused by #16892.

[Veykril]

Can you check if the latest release still runs into this?

[Veykril]

weird that it gets stuck at that status message though, unless something inbetween there panicked causing us to not send the progress end 🤔

[lukas-code]

It's not fixed in rust-analyzer version: 0.4.1889-standalone (5e276ae51 2024-03-20).

Considering that nobody else has complained about this so far, it might be something specific to my system. Let me know if I can do anything to help debug this.

Here is a backtrace if that helps:

Considering that nobody else has complained about this so far, it might be something specific to my system. Let me know if I can do anything to help debug this.

I just had the same issue and I'm pretty sure I'm not you, so ^^'

I did not see the panics in any logs though (might have missed something?...). The only thing I noticed is being stuck building crate graph and loading metadata.

For now switched to release version as it does not have the same bug :')

It is #16892, though I am unsure why

Hello, i'm having the same problem, that the notification is stuck in building CrateGraph. Interestingly enough, autocomplete and go to definition works well in my machine.

As shown in the image, the notification is always loading saying it's building CrateGraph, but the go to definition and autocomplete works fine.
