I've seen this on a number of occasions when my Emacs loaded the .el file instead of .elc on startup because the source file was newer. Then trying to load Eglot complains about this (happened with project or xref).

The way I fixed this at runtime is evaluating (load "project.elc") and then calling M-x eglot again.

I used emacs -Q -f package-initialize and opened a .py progect, M-x eglot worked fine with pylsp server: i was able to do M-? and view xref.

eglot started after commenting the following lines. Do you know how to fix?

;; (use-package ivy-rich
;;   :config (ivy-rich-mode))

and

;; (use-package company
;;   :config
;;   (setq company-idle-delay 0
;; 	company-minimum-prefix-length 1
;; 	company-tooltip-align-annotations t)
;;   (global-company-mode))

ivy-rich calls (require 'project). Sounds like the problem depends on the package load order.

That's not great.

johannesnauta Sep 16, 2024

I am also still having this exact same issue, but something along the lines of

(use-package project
  :ensure t)

at the top of my config still does not solve the issue.

Specific error (which used to be a warning, but now completely bricks eglot), is

Error (use-package): eglot/:catch: Feature provided by other file: project Disable showing Disable logging

It's not easy to analyse any of these will precise reproducible recipes. Also I don't know what the use-package does exactly. I wish people would just type in normal use-package-less-recipes. And show their load paths, etc. (and an Emacs -Q recipe is a great way to do that). All the ivy's and other packages you are using in your complex configs matter. Anyway, I will summon @monnier here, as I believe he may have hints. Eglot's relation with its dependencies -- including project -- is somewhat non-standard because of reasons.

johannesnauta Sep 16, 2024

Yeah it for sure has to do with some packages loading other packages, and one probably loads project before it should. I am in the middle of debugging it with an MWE. If I can reproduce the bug -- which is probably after including a specific package -- I will report back.

If the problem is .el vs elc I think we can consider this a bug in require-with-check, so please M-x report-emacs-bug.
If not, then presumably the problem is that you have two versions of project, installed (probably one coming from Emacs itself and another installed via something like package.el). You need to make sure that the extra installation of project is "active" before the first time a package requires project, otherwise you'll end up loading the old project (the one from Emacs itself).

Normally this happens automatically because all the installed packages (such as project) get activated right before loading your init file (i.e. Emacs calls package-activate-all before loading init.el).

Okay, to debug this further, I suggest you go to the definition of require-with-check (using M-x find-function) and add a printing statement that would print the value of fn (right before cond, for example).

Then you could search for it in load-history and see what the two different filename values are.

johannesnauta Sep 17, 2024

Thanks for the help.

After putting (message "Requiring feature: %s from file: %s" feature fn), this is my *Messages*-buffer after doing load-history:

Note that load-history seems to not contain project.

johannesnauta Sep 17, 2024

I am perhaps also misunderstanding things, but when I omit magit, i.e., I only load eglot, the require-with-check function is not even called? As the above print statements do not seem to appear when only (require 'eglot) is provided.

dgutov Sep 17, 2024

How are you checking that require-with-check is not called?

If you added a message statement right before cond (like I suggested), then it simply won't hit when (eq lh load-history) evaluates to non-nil.

Xephobia Oct 16, 2024

Okay, to debug this further, I suggest you go to the definition of require-with-check (using M-x find-function) and add a printing statement that would print the value of fn (right before cond, for example).

Then you could search for it in load-history and see what the two different filename values are.

I think you can know where a file is loaded by using an advice to call debug when require passed the 'project argument. I added this at the top of my init.el :

(advice-add 'require :before (lambda (feature &optional filename noerror)
			    (if (equal feature 'project)
				(debug))))

By pressing c, I see than in my case, the feature seems to be loaded by python (which is loaded by ob-python for org-babel-load-languages), then projectile, then pet

The question is not just "what loads it" but also why does it load *another* `project.el` file, which is presumably due to a change in `load-path`. So, you need to correlate the above occurrences of requiring `project` with changes to `load-path`. Does one of the above occurrences happen before `package-activate-all` is done?

BTW, I just pushed to Emacs's `master` a change that makes the "Feature provided by other file" error/warning a bit more verbose: it shows both the (new) file that would be loaded now and the file that was previously loaded, both of which presumably provide the same feature.

Thanks, here's the new error:

require-with-check: Feature ‘project’ loaded from "~/vc/emacs-master/lisp/progmodes/project.el" is now provided by "~/vc/emacs-master/lisp/progmodes/project.elc"

How I reproduce it:

Customize load-prefer-newer to t.
Edit project.el in-tree, save it, don't recompile Emacs.
Restart Emacs.
Visit some code file and try to launch M-x eglot there.

I have not solved this for all the packages I work with, but I got it working with the all important magit.

Log eglot first with use-package. defer t
then load magit with defer t and require project before it.

(use-package eglot
  :defer t
  :config
  ;; other stuff ))

(require 'project)

(use-package magit
   :defer t
   )

(add-hook 'csharp-mode-hook 'eglot-ensure)

``` require-with-check: Feature ‘project’ loaded from "~/vc/emacs-master/lisp/progmodes/project.el" is now provided by "~/vc/emacs-master/lisp/progmodes/project.elc" ```

Hmm... yes, this looks like a spurious case, indeed. I guess the issue is that `locate-file` returns the `.elc` file so `require-with-check` thinks we'd load the `.elc` file, but the `load` would under the hood turn around and load the `.el` file instead! So the equality check in `require-with-check` is too strict here.
