Eglot refuses to connect to remote gopls server

[KoltPenny]

Hey,

I'm trying to get eglot to connect to a remote server (which previously worked fine) but today I updated Emacs from 29.1 to 29.3 and it suddenly started refusing to connect.

The remote server showed correct connections by netcat, so I know it's working.

When given a path to the executable, it times out, and when given an address and port, it fails to connect, returning a 127 exit code and a jsonrpc-error.

The only thing I did was fresh install Emacs and install go-mode manually, but I don't think that has to do with this.

Any insights are very much appreciated.

Ack, but M-x eglot-upgrade-eglot and consult the manual for how to report this issue in a way that we can reproduce and analyse and help you. Thanks

Got it.

M-x eglot-upgrade-eglot yield no different results.

When trying to connect to host:port the error message is the following for JSONRPC:

(:message "Running language server: /bin/sh -c stty raw > /dev/null; 192.168.1.167\\:11111")
[internal] Wed Apr 10 11:45:56 2024:
(:message "Connection state changed" :change "exited abnormally with code 127\n")

----------b---y---e---b---y---e----------
[stderr] /bin/sh: 192.168.1.167:11111: command not found

Note that I'm giving it a host and port like I used to do before updating Emacs, when it was working, and now this is the answer.

And when it's done via executable path this is the error:

No disrespect intended, but did you? I was taking about this guide: https://www.gnu.org/software/emacs/manual/html_node/eglot/Reporting-bugs.html Without such information, it is hard to know exactly what happened to you, and thus hard to help you. I understand it's a lot of work, but it's at least worth reading. Anyway, maybe you get lucky just by providing these pieces of information: how exactly do you "give it" a host and a port? Is "it" M-x eglot? Can you go back to Emacs 29.1 where it works and report the same events buffer contents? Thanks

Sorry for some reason I didn't catch that last part. I was kinda busy.

I will re-add what I posted here plus the missing information.

Got it.

M-x eglot-upgrade-eglot yield no different results.

When trying to connect to host:port the error message is the following:

(:message "Running language server: /bin/sh -c stty raw > /dev/null; 192.168.1.167\\:11111")
[internal] Wed Apr 10 11:45:56 2024:

----------b---y---e---b---y---e----------
[stderr] /bin/sh: 192.168.1.167:11111: command not found

Note that, when prompted about either running an LSP or providing a ":", I'm providing the prompt with a host and port like I used to do before updating Emacs, when it was working, and now this is the error output.

This is the debug information for the aforementioned procedure:

Steps to reproduce:

1. Install Emacs 29.3 and go-mode.
2. run gopls on a remote Mac (Sonoma) on port 11111.
3. Download any golang project on said Mac.
4. Connect to the Mac through TRAMP in Emacs and open any file inside the project.
5. M-x eglot.
6. provide host and port.

And when it's provided a path to the executable, eglot times out after 30 seconds and prints this error:

For this test, the debugger doesn't show anything. Eglot just indicates it timed out in the minibuffer.

Note: [REDACTED] parts are sensitive directory names/user names.

Steps to reproduce:

1. Install Emacs 29.3 and go-mode.
2. Download any golang project on a remote Mac (Sonoma), and install &run gopls.
3. Connect to the Mac through TRAMP in Emacs and open any file inside the project.
4. M-x eglot.
5. provide full path to gopls binary.

Eglot version: 1.12.29
Emacs version: 29.3
Linux (where the Emacs client is): Fedora 39.

I think this is all the information I can provide. I tested with a clean install with my config and a clean install without my config.

OK, at least a crucial bit of information is established here (which I suspected): you're using a TRAMP setup. Good! And bad... :-( because these are notoriously difficult to debug, especially if all the information isn't known. But let's not lose hope.

And when it's provided a path to the executable,

By this one sentence I presume that you normally (in 29.1) connect with the "host:port" method, but you also happened to try the "remote executable" method, and it also failed. Am I right?

I think this is all the information I can provide. I tested with a clean install with my config and a clean install without my config.

It's getting much better, but some things are still missing. For example:

• How do you start Emacs, on your local host? Do you click an icon, do you launch it via the shell with /path/to/emacs -Q -f package-initialize? The latter is preferred and the -f package-initialize serves to locate the go-mode.el installation so you can use it in this bare-bones session.
• How exactly do you "connect to the Mac through TRAMP" ? Why do you say you connect and then you open any file? Or do you mean that by visiting a file on the remote host you also establish that connection? What TRAMP method do you use for doing that? Do you use simply C-x C-f? How exactly? C-x C-f /MISTERIOUS-TRAMP-METHOD:/path/to/REDACTED/go/project/main.go?
• Why you say in step 2 of the second recipe that you also "run gopls" on the remote Mac? You wouldn't need to, right? Since the point of this test is to start it remotely.
• What is "the full path to the gopls binary"?

If we're unlucky, this isn't going to be an easy bug to debug. Let's iterate until we have a very good recipe then we can forward all this info to [email protected] and include a TRAMP expert in the loop. The part where you confirm this is a regression from 29.1 is crucial and likely will be of great help in pinning down the problem.

On that note, you seem to have missed this request:

Can you go back to Emacs 29.1 where it works and report the same events buffer contents?

OK, at least a crucial bit of information is established here (which I suspected): you're using a TRAMP setup. Good! And bad... :-( because these are notoriously difficult to debug, especially if all the information isn't known. But let's not lose hope.

Oh dear, lol

By this one sentence I presume that you normally (in 29.1) connect with the "host:port" method, but you also happened to try the "remote executable" method, and it also failed. Am I right?

You are correct. I tried to use the executable because the regular method I used didn't work.

How do you start Emacs, on your local host? Do you click an icon, do you launch it via the shell with /path/to/emacs -Q -f package-initialize? The latter is preferred and the -f package-initialize serves to locate the go-mode.el installation so you can use it in this bare-bones session.

In my Fedora machine, I launch it as a regular gnome application, but running it through terminal gives me the same results. They both run the same config files in the end.

How exactly do you "connect to the Mac through TRAMP" ? Why do you say you connect and then you open any file? Or do you mean that by visiting a file on the remote host you also establish that connection? What TRAMP method do you use for doing that? Do you use simply C-x C-f? How exactly? C-x C-f /MISTERIOUS-TRAMP-METHOD:/path/to/REDACTED/go/project/main.go?

I connect through ssh, exactly with the C-x C-f /ssh:<user>@<host>:/absolute/path/to/go/project/file_in_project.go command.

Why you say in step 2 of the second recipe that you also "run gopls" on the remote Mac? You wouldn't need to, right? Since the point of this test is to start it remotely.

No, it was my lazy ass copy/pasting everything, but in that case I tested closing the server first, even if I originally gave it a different port, just to be sure.

What is "the full path to the gopls binary"?

By this I mean the absolute path.

If we're unlucky, this isn't going to be an easy bug to debug. Let's iterate until we have a very good recipe then we can forward all this info to [email protected] and include a TRAMP expert in the loop. The part where you confirm this is a regression from 29.1 is crucial and likely will be of great help in pinning down the problem.

Oh yeah, forgot to tell you about this. It was working from a different computer with 29.1 but going through a downgrade on the Fedora machine yields the same results.

If it's useful information, the TRAMP version for the downgraded 29.1 is 2.6.0.29.1. Eglot is the same as mentioned before.

I hope we can find a solution to this! Or at least another way to enable the connection to the server.

Sorry I have a tendency to misunderstand things. By this you mean that you confirm that when you downgrade Emacs to 29.1 on your fedora machine:

a) the problem goes away and things work, OR
b) you have the same (disastrous) results as in 29.3.

if your answer is 'a);:

1. can you gather an Eglot events buffer from that 29.1 ? and paste it here?
2. can you retry in that 29.1 after M-x eglot-upgrade-eglot

Unfortunately, b.

UPDATE:

I reinstalled once again 29.3 and go-mode. But, I installed eglot 1.17 manually from the list-packages list. For some reason, emacs ignores that version in favour of the 1.12.x.

I will rebuild from here, bringing over my old config piece by piece.

Another un related note: Whenever I tried to install things I always had my installs stopped by a "Don't call me!" error. Apparently, it's not an issue yet in this new install.

[joaotavora]

So it turns out you weren't using Emacs -Q after all!

This is essential, of course, otherwise "all bets are off"!

This is why I point people so adamantly at this list https://www.gnu.org/software/emacs/manual/html_node/eglot/Reporting-bugs.html

One really must read it. @KoltPenny if you could find the time read it word by word and tell me/us what that text could be improved. So that you would have looked like so you would immediately (or more easily) understand that the problem might lie there.

I've been installing and re-installing these past few hours and you won't believe what happened:

Turns out I can almost pinpoint the culprit of these issues (and many others I had before) to doom themes, modelines and icons. I started installing every package I needed manually (by calling require on the .el files and including the directory where I'm storing them). Apparently, at some point, one of these is requiring compatibility code that messes everything else:

(require 'nerd-icons-faces)
(require 'nerd-icons)
(require 'doom-modeline-core)
(require 'doom-modeline-env)
(require 'doom-modeline-segments)
(require 'doom-modeline)
(require 'doom-themes-base)
(require 'doom-themes)
(require 'doom-rouge-theme)

This is a very obscure issue that I oversaw because the issues where limited to some messages, but now it was making Emacs unusable.

Eglot no longer causes any issues when connecting, nor does TRAMP shows any weird messages about not interpreting remote paths as valid TRAMP paths.

Apologies for the inconvenience, and thanks for being patient with me!
