30.0.50; 'New' error message when using eglot

30.0.50; 'New' error message when using eglot

[Pedro Andres Aranda Gutierrez]

Steps to reproduce:

Install pylsp 1.7.1

emacs -Q -l micro-eglot.el <any python file>

----------- micro-eglot.el -----------------------
(require 'package)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/") t)

(eval-when-compile
  (require 'use-package))
(require 'bind-key)

(setq use-package-always-ensure t)
(unless (file-directory-p package-user-dir)
    (package-refresh-contents))

(use-package jsonrpc
  :ensure nil)

(defun my/eglot-mode-hook ()
  (interactive)
  (message "Adding yasnippets to eglot for %s" major-mode))

(use-package eglot
  :ensure nil
  :defines eglot-server-programs
  :hook ((eglot-managed-mode . my/eglot-mode-hook)
         (python-mode . eglot-ensure))
  :config
  (message "Configuring eglot")
  (setq eglot-server-programs '(;;(python-mode  . ("jedi-language-server"))
                                (python-mode . ("pylsp")))))
----------------------------------------------

You should see:

error in process filter: Wrong type argument: plistp, [] [2 times]

Repeatedly, once the LSP is running

Headaches with a Juju log:
unit-basic-16: 09:17:36 WARNING juju.worker.uniter.operation we should
run a leader-deposed hook here, but we can't yet

Re: 30.0.50; 'New' error message when using eglot

[João Távora]

I don't know what that config is doing (why are you requiring jsonrpc?)
but you seem to be using eglot-ensure in python-mode-hook (maybe,
no idea what use-package is doing).

So in the latest emacs-29, I can't reproduce with this one-liner.  Can you
try it?

emacs -Q --eval '(add-hook (quote python-mode-hook) (function
eglot-ensure))' ~/tmp/coiso.py

This starts up pylsp for me (the only python server I have) and seems to work
normally.  After you try that and presumably reproduce it, try with
M-x toggle-debug-on-error so we can get a backtrace.

Re: 30.0.50; 'New' error message when using eglot

[mprodrigues]

Hello,

I have the same problem.

> emacs -Q --eval '(add-hook (quote python-mode-hook) (function
> eglot-ensure))' ~/tmp/coiso.py

If I use this it works, so maybe the bug is coming from interactions 
with other packages?
I did M-x toggle-debug-on-error so we can get a backtrace, and this is 
what I got:

Debugger entered--Lisp error: (wrong-type-argument plistp [])
   plist-member([] :signatures)
   #f(compiled-function (jsonrpc-lambda-elem10) #<bytecode 
0xdcf9bf12d010fe5>)([])
   jsonrpc-connection-receive(#<eglot-lsp-server 
eglot-lsp-server-186e364> (:jsonrpc "2.0" :id 44 :result []))
   jsonrpc--process-filter(#<process EGLOT (mprodrigues/(python-mode 
python-ts-mode))> "Content-Length: 37\15\nContent-Type: 
application/vsco...")

It would surely seem so, as eglot.el doesn't have very many plist-member
calls, and none of them for the ':signatures' key.

So someone is going to go throught the trouble of making a reproducible
error recipe (or bisecting a configuration), otherwise I can't be of
much help.

It would also help to see what the the client request for :id 44 was in
the first place.  You could find that in the buffer brought to you by
M-x eglot-events-buffer

Re: 30.0.50; 'New' error message when using eglot

[mprodrigues]

So in my case the culprit was doom-modeline, I guess that is because it 
was trying
to call eglot--spinner, but that doesn't exist anymore. Anyway, I was 
expecting this
to be a warning on their side, not outright mess with eglot functioning. 
This has
already been reported on their side and I guess the fix is in the next 
release.

Thanks.

Mateus Rodrigues

OK.  See the double '--' in there? That's a notice to third party
developers that the symbol is internal, an implementation detail, that
shouldn't be relied upon from packages outside the origin of the
symbol.  Unfortunately, this warning often goes unheeded.
