rust-analyzer: Critical bug that completely prevents the use of rust-analyzer (1.78.0-nightly (3246e79 2024-02-19) in VS Code (1.86.2)

This is a serious regression in nightly and it’s important to fix it before the next release.

rust-analizer extension: v0.4.1853 (pre-release) rust-analyzer: 1.78.0-nightly (3246e79 2024-02-19) rustup: 1.26.0 (1980-01-01) rustc: 1.78.0-nightly (3246e7951 2024-02-19) VS Code: 1.86.2

rust-analyzer analysis-stats . the output is: https://pastebin.com/YRNzDaXV

RA_LOG=info rust-analyzer analysis-stats . the output is so big that I had to upload it to Mega.nz: https://mega.nz/file/IsIATYSR#LQMQZy5FR0JrXpB27J6dI8igABvMioHzaaiaExbfvfI

the Output inside VS Code is:

Same here, but I use rust-analyzer on Nvim with Mason.

I resolved by downgrading rust-analyzer to the 2024-02-11 version.

Wasn’t able to reproduce it on today’s and yesterday’s nightly r-a on tree-sitter

dang, I just reproduced it with today’s nightly as well. I use neovim not vscode though fwiw, but that shouldn’t really affect how r-a behaves.

like @felipelalli said ^^ I’m happy to help debug further, just need pointers

What debugging strategies do you suggest for resolving this issue? It’s significantly hindering my daily tasks.

felipelalli on Feb 21, 2024

The bug exists in the proc-macro server (a rustup component) so you’ll have to update your rust toolchain to tomorrows nightly (as the sync only happened today). Hence why downgrading didn’t help either for you

Veykril on Feb 25, 2024

Are any particular steps needed to reproduce?

Just open VS Code.

The rust-analyzer is able to make like a “first analysis”. So, if I keep closing / opening / closing it is possible to detect some errors / warnings in the project. But few seconds later it starts to panic and the rust-analyzer doesn’t work at all.

Might be https://docs.rs/indoc/latest/indoc/ causing troubles again given the linked source snippet

I am working on just one project in Rust. Do you recommend any specific open source project to test?
