How to reproduce the issue

How to reproduce this exactly is something I'm still trying to figure out. The problem is as follows:

When using rust-analyzer, after a while old diagnostics stick around, even after fixing them. Looking at the LSP debug logs, the diagnostics are not produced by rust-analyzer, so it's not a case of a language server producing incorrect diagnostics.

Looking at the buffer cache for an affected buffer, it seems the stale diagnostics are produced for a different (perhaps older?) namespace. For example, the output is as follows:

{
  [15] = { {
      bufnr = 15,
      col = 0,
      end_col = 23,
      end_lnum = 10,
      lnum = 10,
      message = "remove the whole `use` item",
      namespace = 15,
      severity = 4,
      source = "rustc",
      user_data = {
        lsp = {

    } }
}

Here namespace 15 contains the stale diagnostics. New diagnostics in turn are produced under namespace 13. Using vim.diagnostic.get_namespace for these namespaces produces the following:

{
  name = "vim.lsp.rust_analyzer.1",
  opts = {},
  user_data = {
    sign_group = "vim.diagnostic.vim.lsp.rust_analyzer.1",
    underline_ns = 14
  }
}

{
  name = "vim.lsp.rust_analyzer.2",
  opts = {},
  user_data = {
    sign_group = "vim.diagnostic.vim.lsp.rust_analyzer.2",
    underline_ns = 16
  }
}

Based on the above, it seems that somewhere along the lines, NeoVim starts using a new namespace for new diagnostics, leaving the old diagnostics (in the old namespace) as-is. Clearing the old ones using vim.diagnostic.reset(15, 0) clears them up, and after that they don't show up (until you run into the problem again in a different buffer).

Expected behavior

Given language server X, I would expect it to always use the same namespace Y, ensuring diagnostics don't become stale.

Actual behavior

A new namespace appears to be used somewhere along the lines, resulting in old diagnostics not getting cleaned up when they are fixed.

yorickpeterse commented 2 years ago

Looking at the namespace names, which include the client ID, it seems the issue here is a new client ID being used, thus resulting in a new namespace. I wonder if this can happen when the language server crashes and restarts.

gpanders commented 2 years ago

It looks like the original client for rust-analyzer is being replaced by a new one, though I’m not sure why this would be happening. @neovim/lsp can you chime in on this?

mjlbach commented 2 years ago

Depends, if you close the client it should clean up the old namespace, unless there is a bug in the shutdown code. Are two running at the same time?

yorickpeterse commented 2 years ago

@mjlbach I only have one client for Rust configured (that being rust-analyzer), and I don't run anything like e.g. LspRestart. I wonder if this may happen when rust-analyzer panics, maybe that prevents neovim from detecting this/cleaning things up?

mjlbach commented 2 years ago

Maybe but we shouldn't auto-restart the language server (see later comment) and we should clean up when the client closes... If you can get a log from the repro we can check for panics/a call to start_client that would indicate the lspconfig autocommand triggered starting a second language server

@mjlbach The logs don't really show anything super interesting roughly around the time I got it to show stale diagnostics:

I'm now experimenting with rust-analyzer's own logging (per https://github.com/rust-analyzer/rust-analyzer/blob/86ebc36fa3a4924d169884b42a0d8286da0cb53e/docs/dev/README.md#logging).

I think I found out what the issue is, and it's not a crash (I think?):

My project consists of three crates (compiler, vm and cli). These are configured using Rust/Cargo workspaces. When I open a file in any of the projects on its own, everything is fine. If I then open a file in a different crate, it seems to result in a new client being produced. From this point forward, existing diagnostics are never cleared out. Here's a recording showing the issue:

asciicast

And the logs:

mjlbach commented 2 years ago

Can you show LspInfo? If so, this is more of an lspconfig issue than core.

yorickpeterse commented 2 years ago

When there's only 1 client and all is working well:


 Language client log: /home/yorickpeterse/.cache/nvim/lsp.log
 Detected filetype:   rust

 1 client(s) attached to this buffer:

After opening a file in a different workspace crate, and a new client/namespace is used:

mjlbach commented 2 years ago

Yep, lspconfig bug.

yorickpeterse commented 2 years ago

Looking at lspconfig, it seems to use Cargo.toml as the workspace root file:

https://github.com/neovim/nvim-lspconfig/blob/a96ab275dbe2827eec9467a86940c1bc48589c82/lua/lspconfig/rust_analyzer.lua#L18-L54

This won't work well I think for multi-crate projects, as each crate has its own Cargo.toml, but there's only one shared Cargo.lock. Perhaps it should find Cargo.lock and fall back to Cargo.toml if none could be found?

mjlbach commented 2 years ago

It doesn't use cargo.toml directly, it calls

'cargo metadata --no-deps --format-version 1 and pulls workspace_root out of that

yorickpeterse commented 2 years ago

OK I seem to be an idiot. Unknown to present-day me, I had this line in my rust-analyzer config:

root_dir = config.util.root_pattern('Cargo.toml', 'rustfmt.toml')

This line results in the root directory becoming that of the crate, not the root of all the crates. If I remove that line, it seems all is well.

I guess the moral of the story here is to not report bugs after midnight :man_facepalming:

mjlbach commented 2 years ago

Lmao its ok, we've all been there. LMK if there is something I should improve in the default lspconfig root pattern :)
