Re: gnus-timer--function is void (was Re: Gnus freezes on startup)

[Marius Hofert]

Hi,

I work with Emacs 24.2.1 on Ubuntu 12.10 and wanted to use the latest version
of Gnus. I git-cloned to ~/.emacs.d (then ./configure, make) and ~/.emacs contains:

--8<---------------cut here---------------start------------->8---
(setq load-path (cons (expand-file-name "~/.emacs.d/gnus/lisp") load-path))
(require 'gnus-load)
(require 'info)
(add-to-list 'Info-default-directory-list "~/.emacs.d/gnus/texi/")
--8<---------------cut here---------------end--------------->8---

On startup of Gnus, I obtain:

,----
| gnus-group-highlight-line: Symbol's function definition is void:
| gnus-get-text-property-excluding-characters-with-faces
`----

That's the backtrace (with M-x toggle-debug-on-error):

,----
| Debugger entered--Lisp error: (void-function gnus-get-text-property-excluding-characters-with-faces)
|   gnus-get-text-property-excluding-characters-with-faces(1 face)
|   gnus-group-highlight-line("dummy.group" 1 23)
|   gnus-group-insert-group-line("dummy.group" 0 nil 0 nil)
|   gnus-update-group-mark-positions()
|   gnus-group-mode()
|   gnus-group-setup-buffer()
|   gnus-group-list-groups(nil)
|   byte-code("\b\204
`----

I then have executed gnus-get-text-property-excluding-characters-with-faces by hand
(with C-x C-e). Afterwards, Gnus starts and I can also write mails. For testing
purposes, I sent myself a mail. When I wanted to open it, I obtained:

,----
| gnus-article-stop-animations: Symbol's function definition is void: gnus-timer--function
`----

... and this is how I found this post. 

I then executed this auxiliary function:

--8<---------------cut here---------------start------------->8---
(let ((name "gnus-util")
      (load-path (copy-sequence load-path))
      elc el files dir)
  (while (setq elc (locate-library name))
    (push elc files)
    (setq dir (file-name-directory elc))
    (when (setq el (locate-library (concat name ".el")))
      (unless (equal el elc)
	(push el files)))
    (setq load-path
	  (delete dir (delete (directory-file-name dir) load-path))))
  (nreverse files))
--8<---------------cut here---------------end--------------->8---

and obtained:

("/home/mhofert/.emacs.d/gnus/lisp/gnus-util.elc" 
 "/home/mhofert/.emacs.d/gnus/lisp/gnus-util.el" 
 "/usr/share/emacs/24.2/lisp/gnus/gnus-util.elc" 
 "/usr/share/emacs/24.2/lisp/gnus/gnus-util.el.gz")

=> fine.

I also execute the following (with minimal ~/.gnus.el and ~/.emacs) as Katsumi:

--8<---------------cut here---------------start------------->8---
emacs -batch -Q -l gnus-art -eval '(message "%s" (gnus-timer--function
(timer-create)))'
--8<---------------cut here---------------end--------------->8---

-eval '(message "%s" (gnus-timer--function (timer-create)))'
--8<---------------cut here---------------end--------------->8---

,----[ output (same as Katsumi's): ]
| nil
`----


I then also tried to use Emacs snapshot (also from ppa:cassou/emacs), but
obtained even more obscure behavior. 

I'm not an elisp programmer, just wanted to report what I found. I hope an
expert looks into this. If you need more information, please give me detailed
instructions to minimize the risk of "informational loss on debugging".

Cheers,

I tried the same, with the ~/.emacs file including only two lines
similar to yours, but got no problem.  Hmm.  Could you send me
a tarball that includes at least the following files in your
~/.emacs.d/gnus/lisp" directory?

gnus-art.el
gnus-art.elc
gnus-util.el
gnus-util.elc

I suspect something bad happened when you performed ./configure
and make.

Was this ever resolved? I am seeing the same behaviour with emacs 24.3 on 
ArchLinux. The problem does not occur if I revert to emacs 24.2 . Please copy 
replies to my address, I am not on the list.

I sorted out that 24.3 (as packaged for Arch) started including
Gnus. Even though the git version ghosted the system version; there was
apparently some conflict.

I've reverted to the system version for now.

I think there's no reason except for loading an old gnus-util.elc.
I mean that *old* is that of Emacs 24.3 or that of older versions
of Gnus.  If you use Ma Gnus without removing Gnus that Emacs 24.3
bundles, the path for Ma Gnus has to be put high on `load-path' than
the one for Gnus Emacs 24.3 bundles.  An easy way to do that is:

(push "/Directory/Where/Ma_Gnus/Is/Installed" load-path)

Hmm, but it should be loaded by way of the following ones:

::: gnus-art.el :::
(require 'gnus)

::: gnus.el :::
(require 'gnus-util)

That's a mystery.  I normally use Emacs 24.2.50 but tried 24.2
(for which Ma Gnus has not been installed).  Here are the ones I
observed:

/usr/bin/emacs --version
 => GNU Emacs 24.2.1

# This should not work because of the absence of Ma Gnus.
/usr/bin/emacs -batch -Q\
 -l gnus-art\
 -eval '(message "%s" (gnus-timer--function (timer-create)))'
 => Symbol's function definition is void: gnus-timer--function

# This should work.
/usr/bin/emacs -batch -Q\
 -eval '(push "/Ma Gnus source directory/lisp" load-path)'\
 -l gnus-art\
 -eval '(message "%s" (gnus-timer--function (timer-create)))'
 => nil (ok)

# This should work(2).
/usr/bin/emacs -batch -Q\
 -f batch-byte-compile '/Ma Gnus source directory/lisp/gnus-util.el'
 => Wrote /Ma Gnus source directory/lisp/gnus-util.elc

/usr/bin/emacs -batch -Q\
 -eval '(push "/Ma Gnus source directory/lisp" load-path)'\
 -l gnus-art\
 -eval '(message "%s" (gnus-timer--function (timer-create)))'
 => nil (ok)

It shows as expected, new one ahead of the older one. 

gnus-timer--function is used in gnus-art.el (in
gnus-article-stop-animations ()). It is not defined on first
invocation. That's what the stack shows:

gnus-article-stop-animations: Symbol's function definition is void:
gnus-timer--function [2 times]

  gnus-timer--function([nil 20595 12692 388485 900 nnimap-keepalive nil nil])

Well, don't you have the old gnus-util.el file(s) in your load-path
directories?  This should show the most preferred one among them:

M-x locate-library RET gnus-util RET

And this shows all the gnus-util.el(c) files existing in
the load-path directories:

(let ((name "gnus-util")
      (load-path (copy-sequence load-path))
      elc el files dir)
  (while (setq elc (locate-library name))
    (push elc files)
    (setq dir (file-name-directory elc))
    (when (setq el (locate-library (concat name ".el")))
      (unless (equal el elc)
	(push el files)))
    (setq load-path
	  (delete dir (delete (directory-file-name dir) load-path))))
  (nreverse files))

;; Copy this form to the *scratch* buffer and type `C-j' at the end.

I just hit the same problem as well, after moving to MaGnus
0.6. Started using the same workaround as Johnny described, but

gnus-timer--function is void (was Re: Gnus freezes on startup)

[Johnny]

Thanks all for the pointers in faultfinding the Gnus freeze (below), I
have finally got Gnus back working (re-install of F17, it was about time
anyhow). 

There is one final bit I don't get; after installing Ma Gnus v0.6 I
cannot open any messages from the summary buffer as I get the error
message 'gnus-timer--function is void'. I can see this is defined in
gnus-utils.el 

,----
| (if (fboundp 'timer--function)
|     (defalias 'gnus-timer--function 'timer--function)
|   (defun gnus-timer--function (timer)
|     (elt timer 5)))
`----

The load path is set correctly I assume (as it picks up Ma Gnus
correctly) and I have the 'require gnus-load' in .init.el:

,----
|   (add-to-list 'load-path "/usr/local/share/emacs/gnus/lisp")
|   (add-to-list 'load-path "/usr/local/share/emacs/gnus/contrib")
|   (require 'gnus-load)
`----

I 'solved' the issue by copying the part from gnus-utils.el to my
init.el, but this doesn't seem right. Am I missing something here?

Thanks,

Johhny
