Subject: 29.0.60; function-history: M-. fails to jump to defun if
 straight.el straight-cache-autoloads is enabled
Date: Sun, 04 Dec 2022 18:44:16 +0900

Hello, Emacs

M-. fails to jump to defun if autoload forms are evaluated in init.el
without `load'; it is the way of straight.el autoloads cache feature
(enabled by default):

  https://github.com/radian-software/straight.el/blob/master/straight.el

  straight--activate-package-autoloads
  straight--read-package-autoloads


----------------------------------------
1. Create the following autoload files and init.el;

~/.emacs.d/site-lisp/loadhist--foo.el

#+begin_src emacs-lisp
(defun loadhist--foo-inc (x) (1+ x))
(provide 'loadhist--foo)
#+end_src

~/.emacs.d/site-lisp/loadhist--foo-autoloads.el

#+begin_src emacs-lisp
(autoload 'loadhist--foo-inc "loadhist--foo")
(provide 'loadhist--foo-autoloads)
#+end_src

~/.emacs.d/init.el

#+begin_src emacs-lisp
(setq load-path (cons (locate-user-emacs-file "site-lisp") load-path))

;; BACKGROUND
;;
;; The following code is the way of straight.el autoloads cache:
;;
;; https://github.com/radian-software/straight.el/blob/master/straight.el
;;
;; straight--activate-package-autoloads
;; straight--read-package-autoloads
;;

(let ((load-file-name (locate-user-emacs-file "site-lisp/loadhist--foo-autoloads.el"))
      (load-in-progress t))
  (with-temp-buffer
    (insert-file-contents load-file-name)
    (let (autoloads)
      (condition-case _
          (while t
            (push (read (current-buffer)) autoloads))
        (end-of-file))
      (dolist (form (nreverse autoloads))
        (eval form)))))

(message "function-history A: %s" (get 'loadhist--foo-inc 'function-history))

;; M-. fails to jump to defun in loadhist--foo.el
;; if loadhist--foo.el is loaded:
(message "(loadhist--foo-inc 1): %s" (loadhist--foo-inc 1))

(message "function-history B: %s" (get 'loadhist--foo-inc 'function-history))
#+end_src


----------------------------------------
2. launch Emacs, and open init.el, then M-. on `loadhist--foo-inc';


----------------------------------------
3. M-. jumps to the head of init.el instead of defun in loadhist--foo.el;
   (MISBEHAVIOR)

   In *Messages*, (get 'loadhist--foo-inc 'function-history) says:

#+begin_example
function-history A: nil
(loadhist--foo-inc 1): 2
function-history B: (/home/naofumi/.emacs.d/site-lisp/loadhist--foo.el (autoload loadhist--foo nil nil nil))
#+end_example


----------------------------------------
4. Comment out (loadhist--foo-inc 1) call in init.el, then do #2 again;

#+begin_src diff
--- init.el.orig	2022-12-04 16:16:01.513979076 +0900
+++ init.el	2022-12-04 16:17:34.347794827 +0900

#+end_src


----------------------------------------
5. M-. jumps to defun in loadhist--foo.el;
   (EXPECTED)

----------------------------------------


I found that the following commit affects to this behavior.  If I revert
this commit, M-. jumps successfully even if loadhist--foo.el is
autoloaded by (loadhist--foo-inc 1) call in init.el.

What makes you think this is a bug in Emacs, and not in straight?

Did you report this to the straight developers first?

Thanks.

I thought that it could be an issue of Emacs-side because:

a) What straight.el does is just `eval' of autoload forms;
b) M-. failure is reproducible without straight.el;
c) Autoloading itself works fine even if autoload forms are evaluated
   without `load';
d) It works well with Emacs <= 28;

> Did you report this to the straight developers first?

No, I didn't.  But the following Github issue might be the same:

  C-h f for some functions link to the loading file instead of their source file:
  https://github.com/radian-software/straight.el/issues/1022


I tried to find more simple recipe.  Could you try this with emacs-29
or master?

----------------------------------------
1. Create the following file

~/.emacs.d/site-lisp/loadhist--foo.el

#+begin_src emacs-lisp
(defun loadhist--foo-inc (x) (1+ x))
(provide 'loadhist--foo)
#+end_src

----------------------------------------
2. emacs -Q

----------------------------------------
3. Insert the following to *scratch*

#+begin_src emacs-lisp
(setq load-path (cons (locate-user-emacs-file "site-lisp") load-path))
(autoload 'loadhist--foo-inc "loadhist--foo")
(message "(loadhist--foo-inc 1): %s" (loadhist--foo-inc 1))
#+end_src

----------------------------------------
4. In *scratch*, M-x eval-buffer

----------------------------------------
5. M-. on `loadhist--foo-inc'
=>
xref--not-found-error: No definitions found for: loadhist--foo-inc

----------------------------------------
6. In *scratch*, M-x eval-buffer again

----------------------------------------
5. M-. on `loadhist--foo-inc'
=>
Jumps to defun in ~/.emacs.d/site-lisp/loadhist--foo.el

----------------------------------------


Best regards,
  Naofumi

Thanks for the clear recipe.

I can reproduce this on master, but not every time.  Sometimes it works
even after one `eval-buffer'.  For some reason, it seems to work more
often when I remove the third line with `message'?

Something definitely seems wrong with the autoloading and/or xref here.

I'm not sure I understand the issue, and I'm not familiar with
straight.el, but if the above somehow prevents the function from being
loaded, it is expected that M-. will fail.  Its ELisp backend works
only for loaded functions.  If you want it to work for functions that
aren't loaded, you need to manually switch the backend to etags.

So if the above scenario worked with Emacs 28, I suggest to check
whether the function was being loaded with Emacs 28.

On my systems (debian bullseye box and x86 macOS laptop), M-. failure
happens every time.  If the third (message .. (loadhist--foo-inc 1)) is
not exist, M-. on `loadhist--foo-inc' works:

#+begin_src emacs-lisp
(setq load-path (cons (locate-user-emacs-file "site-lisp") load-path))
(autoload 'loadhist--foo-inc "loadhist--foo")
;; (message "(loadhist--foo-inc 1): %s" (loadhist--foo-inc 1))
#+end_src


If the third (message .. (loadhist--foo-inc 1)) is replaced with
`require', M-. on `loadhist--foo-inc' also fails:

#+begin_src emacs-lisp
(setq load-path (cons (locate-user-emacs-file "site-lisp") load-path))
(autoload 'loadhist--foo-inc "loadhist--foo")
(require 'loadhist--foo)
#+end_src

It is that I actually noticed this issue for the first time.

Best regards,
  Naofumi

The function `loadhist--foo-inc' is definitely loaded by autoload,
but M-. fails to find defun in the source file loadhist--foo.el.

I've tried to check the state of load-history (both 28 and 29) and
function-history (29-only).  The following is the difference between
Emacs 28 and 29:

;;------------------------------------------

;; Step 2: emacs -Q

;; Step 3: In *scratch*, M-x eval-buffer

(setq load-path (cons (locate-user-emacs-file "site-lisp") load-path))
(autoload 'loadhist--foo-inc "loadhist--foo")
(message "(loadhist--foo-inc 1): %s" (loadhist--foo-inc 1))

;;------------------------------------------
;; Step 4: Check load-history

(symbol-file 'loadhist--foo-inc 'defun)
=> "/home/naofumi/.emacs.d/site-lisp/loadhist--foo.el"

(let (matches)
  (pcase-dolist (`(,file . ,elems) load-history)
    (when (rassq 'loadhist--foo-inc elems)
      (push (cons file elems) matches)))
  (nreverse matches))
=> ((nil (autoload . loadhist--foo-inc)) ("/home/naofumi/.emacs.d/site-lisp/loadhist--foo.el" (t . loadhist--foo-inc) (defun . loadhist--foo-inc) (provide . loadhist--foo)))

Sorry. In autoload-only case, the difference is just
Emacs 29 (defun. loadhist--foo-inc) and
Emacs 28 (autoload . loadhist--foo-inc).

`symbol-file' returns autoload file.
