Connection issues with lsp-bridge-enable-with-tramp and doom emacs #769

Bawaw · 2023-11-09T09:36:27Z

Hey, thank you for this package, it is the best experience I've had with LSP in emacs so far!

However, while trying to integrate lsp-bridge in my daily workflow (doom emacs + remote pyright) I hit a block. When I (setq lsp-bridge-enable-with-tramp 't) I fail to connect to the LSP server when opening a file using tramp (see logs below).

PS: When opening a remote file using lsp-bridge-open-remote-file everything works as expected.

The problem seems to be that lsp-bridge cannot get the remote hostname. Are you using the ssh protocol? If so, please provide the tramp path of the file and the ssh config file. Thanks.

Bawaw · 2023-11-09T10:13:23Z

Yes, I'm using the ssh protocol. The path would look something like this:
/ssh:bawaw@remotehostname:/usr/local/project/main.py

My SSH config file would then look like this:

Host remotehostname
  HostName remotehostname
  User bawaw

werhner · 2023-11-10T03:12:33Z

This question seems similar to issue #758. Is the host name defined in .ssh/config in domain name format rather than IP format?

Bawaw · 2023-11-10T07:44:45Z

The config is indeed defined in name format. However, I also tried using ip format:
/ssh:[email protected]:/usr/local/project/main.py

With config:

Host x.x.x.x
  HostName x.x.x.x
  User bawaw

I get a slightly different error this time:

werhner · 2023-11-14T11:30:08Z

Please update to the latest version and then execute lsp-bridge-tramp-show-hostnames function.
After that, check if the output of the host configuration options meets expectations.
The HostName should be in the IP format.

Bawaw · 2023-11-15T09:26:54Z

Hm, I'm still getting the error even when using the ipv4 format. Here is the complete stacktrace when I first try to connect to a file and then run lsp-bridge-tramp-show-hostnames:

werhner · 2023-11-15T10:18:43Z

According to the provided log, it seems that the issue lies in the encryption of the private key file. Paramiko raised a PasswordRequiredException exception. Is your key file encrypted?

Bawaw · 2023-11-15T10:19:29Z

Alright so removing the password from my private key circumvented the encryption problems but when I connect I still get the following error:
*messages*: or: Wrong type argument: lsp-bridge-epc-manager, nil
*lsp-bridge*: ERROR:epc:ReturnError([Symbol('wrong-type-argument'), Symbol('stringp'), []])

With logging enabled I now get:

Eval in Emacs: (lsp-bridge--first-start '46367)
ERROR:epc:ReturnError([Symbol('wrong-type-argument'), Symbol('stringp'), []])
Eval in Emacs: (message '"[LSP-Bridge] Connect [email protected]#22...")

I also noticed that in the following 3 scenario's the program behaves differently:

lsp-bridge-open-remote-file I get or: Wrong type argument: lsp-bridge-epc-manager, nil and nothing happens.
When I first enable logging and then use lsp-bridge-open-remote-file I also get the epc error but the file does open.
When I first open a file using tramp and then use lsp-bridge-open-remote-file it also and I also get the epc error

The autocomplete also does not seem to be working when I'm using lsp-bridge-open-remote-file, I'm sorry for not noticing this earlier. I get the [LBR] file-name buffer but the autocomplete only returns some yas-snippets and search words.

werhner · 2023-11-15T10:38:50Z

In the opening tramp file, will the autocomplete return some yas-snippets or nothing at all?
Please provide the log of remote lsp-birdge process.

Bawaw · 2023-11-15T11:01:10Z

When I open the file using tramp I get the following logs:

Eval in Emacs: (lsp-bridge--first-start '43967)

Autocomplete returns yas-snippets and search words:

But no real lsp functionality:

werhner · 2023-11-15T11:35:49Z

It seems that there are no issues with the SSH connection and LSP completion. The only problem is that your Emacs is not displaying the completion results. Can you open a local Python file to see if LSP completion results are displayed correctly?

Perhaps you can submit a new issue explaining the current problem to get more help. I am more familiar with the remote editing part, and apologize for not being able to provide more assistance with the display issue.

Bawaw · 2023-11-15T11:52:15Z

I think indeed think that this is a problem on the display side of things. I've noticed that sometimes I do get autocomplete, sometimes I get a different autocomplete and sometimes I do not get any completion. I'll play around with it a bit more and if I do not find the cause I'll create a new issue.

There is one more problem on the remote connect side of things though (I think). When I open a file using tramp and I do not set lsp-bridge-enable-log I never get real autocomplete and the server does not build a connection.

Sever log:
* Running lsp-bridge in remote server, use command 'lsp-bridge-open-remote-file' to open remote file.

manateelazycat · 2023-11-15T12:41:46Z

I commit a565130

You can turn on lsp-bridge-enable-log, lsp-bridge will print debug message for completion predicate result, if result is nil, that's why completion menu not popup.

manateelazycat · 2023-11-26T01:10:38Z

Did you test with emacs -Q?

I guess other package in Doom will conflict with lsp-bridge.
