rust-analyzer crashes on Qt Creator 8

[lnicola]

    > @installgentoo the QtCreator report seems unrelated. Depending on whichever problem you're running into, consider running `cargo check` from the terminal to watch the registry being updated, or filing a new issue whatever panic Qt Creator is running into.

in the latest log that i ran with debug i get

        "code": -32801,
        "message": "waiting for cargo metadata or cargo check"
    },

and then analyzer crashes. Notably everything works on 7, where QtCreator apparently communicated synchronously to the server(or ignored "Initialized" response, i'm not quite sure yet), creator displays a little "cargo check" progress popup. And everything indeed fetches and works.

@installgentoo my Qt Creator doesn't seem to support Rust or Cargo projects and I don't see any plugin for it. Do you have some tips to get it working? I'll try to take a look tomorrow.

If not, you could use strace on the server process to see the panic message.

Ref https://bugreports.qt.io/browse/QTCREATORBUG-27856.

[ERROR rust_analyzer] Unexpected error: client exited without proper shutdown sequence

The linked issue says that Qt Creator isn't closing our input.

[installgentoo]

you set this in options and rls.sh is just

#!/bin/bash
export CARGO_HOME="/_/code/.cache_rust"
export CARGO_TARGET_DIR="/_/code/.cache_rust"
/home/user/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin/rust-analyzer "$@"

You can simply create new plain-c project, and then "Add all files from directory" by right-clicking on the project name.

I've attached a log of all messages send between the client and the server.
rust-analyzer.log

Qt people fixed it, might be relevant to parent issue.

Yeah, https://bugreports.qt.io/browse/QTCREATORBUG-27856 seems fixed and points to https://bugreports.qt.io/browse/QTCREATORBUG-28598.
