Too many same issues reported in problem console by rust-analyzer in vscode remote server mode

[cokeBeer]

rust-analyzer version: rust-analyzer version: 0.3.1481-standalone

rustc version: rustc 1.65.0 (897e37553 2022-11-02)

relevant settings: None

I am using vscode remote server mode with rust-analyzer. Too many same issues.

Are you using a VS Code workspace?

[cokeBeer]

Yes

[lnicola]

We currently run cargo check on each workspace member, and there's no easy way to avoid it. I suggest going for a plain Cargo workspace if possible.

[cokeBeer]

So why the issues are same ? Seems one file is checked many times and reported.

[lnicola]

If I understand correctly, on a Code workspace with library L and projects A and B, both depending on it, we'll run cargo check three times, for each crate.

So if L has an error, we'll report it once for L, once for A and once for B. Three times.

[cokeBeer]

No, the issue comes from mod.rs, which is only used in this project and the issue is reported 5 times. (Are you talking about cargo workspace with many members instead of vscode workspace ? I mean, I am opening the folder as vscode workspace. )

[lnicola]

Well, I don't know, and it might be hard to tell without a sample project showing the problem.

@lnicola The comand ps -ef|grep rust shows there are 5 rust-analyzer and the number is the same as issues. Does it help ?

I think there's a discussion of a similar issue under #13954 (comment).

Five rust-analyzer-proc-macro-srv instances indicates you have a Code workspace with five members. You're also getting an error duplicated five times. It's likely that these are related.

@lnicola Hi, I've read that issue now. However, I only open one workspace as it mentioned above and the project is standalone and has no members. So maybe I am not matching the situation in #13954. But I can provide some additional information that, the standalone project is a sub folder under a git repo, like

git_repo_root
-- my_rust_project
-- my_java_project
-- my_c_project

All other projects are not written in rust. If I open the folder git_repo_root directly, the number of issues and rust-anaylzer is right ( only 1 ).
Maybe the problem is associated with git ?

[lnicola]

Do you have a Cargo.toml under git_repo_root?

[cokeBeer]

No, only a Cargo.toml under my_rust_project

[package]
name = "fuzzer"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
libafl = { git = "https://github.com/AFLplusplus/LibAFL.git", rev = "0727c80" }

@lnicola Hi, I see. This is my my_rust_project/.vscode/settings.json. I don't know why but there are 5 Cargo.toml in it.

{
    "rust-analyzer.linkedProjects": [
        "./Cargo.toml",
        "./Cargo.toml",
        "./Cargo.toml",
        "./Cargo.toml",
        "./Cargo.toml"
    ],
    "rust-analyzer.showUnlinkedFileNotification": false
}

After I delete them, everything is ok. Thanks for your help.

[lnicola]

Right. There's was a bug where we asked about adding new projects there, and took No for a yes, and the other way around 😄.
