...and therefore, it spawns separate language servers for every sub-directory (which doesn't happen when you visit the same "project" locally).

Applying this workaround helps, but as I understand, one of Eglot's design decisions is not to rely on external packages like Projectile - hence I'm reporting this as an issue.

Steps to reproduce:

  1. Log into some remote Linux machine.
  2. Create a simple foobar "project" with the snippet below:
mkdir -p foobar/foo foobar/bar
echo "int main(){}" > foobar/foo/foo.cc
echo "int main(){}" > foobar/bar/bar.cc
git init foobar
  1. From within Emacs running on your local machine, C-x C-f to foo.cc via TRAMP, e.g. /ssh:my-remote-machine:foobar/foo/foo.cc.
  2. In a similar fashion, C-x C-f to bar.cc.

Result (see in *Messages* buffer):

[eglot] Connected! Server `clangd' now managing `c++-mode' buffers in project `foo'.
[eglot] Connected! Server `clangd' now managing `c++-mode' buffers in project `bar'.

Expected:

[eglot] Connected! Server `clangd' now managing `c++-mode' buffers in project `foobar'.

(i.e. the same outcome when you repeat steps 2-4, modulo TRAMP, on your local machine)

Details:

  • Server used: clangd (but I think this issue is server-agnostic)
  • Emacs version: GNU Emacs 27.1 (build 1, x86_64-apple-darwin18.7.0, Carbon Version 158 AppKit 1671.6) of 2020-11-21
  • Operating system: macOS (locally), Linux (remotely)
  • Eglot version: 20220123.1406
  • Eglot installation method: package.el
  • Using Doom: No

LSP transcript - M-x eglot-events-buffer (mandatory unless Emacs inoperable)

I agree this should be server-agnostic, but I've failed to reproduce it with rust-analzer. Do you still see the issue with the latest Eglot? What's the result of the following command if you start it from the buffer of the remote foo.cc?

   M-: (project-current) RET

Turns out that this behaviour is caused by my config:

; disable vc to avoid delays ("Tramp: Checking ‘vc-registered’" msgs etc.)
(setq vc-ignore-dir-regexp
      (format "\\(%s\\)\\|\\(%s\\)"
              vc-ignore-dir-regexp
              tramp-file-name-regexp))

I've omitted this "detail" from from my bug report because I thought it was irrelevant (sorry for that! I should've followed the instructions more closely 🤦🏻‍♂️).

But! There's actually some gain here 😉

While investigating this, I've discovered another thing, which may be a somewhat known problem: having foo.cc opened (and handled successfully by Eglot), C-x C-f to bar.cc gives:

error in process filter: tramp-error: peculiar error: "Forbidden reentrant call of Tramp"
error in process filter: peculiar error: "Forbidden reentrant call of Tramp"

...but this probably requires a separate bug report, which I'll provide shortly (say, tomorrow) 😺

Turns out that I can easily reproduce this error with Eglot 20220123.1406 (and for that matter, TRAMP 2.5.2), but after switching to Eglot's current master (i.e. 8dc5180), it doesn't appear anymore.

Acutally, I can reproduce it on current master too - see #859.
