Gnus freezes on startup

Gnus freezes on startup

[Johnny Carlsson]

Hi all,

Recently I have been unable to start gnus on my machine and am completely unable to debug why. This was around two weeks ago - incidentally I created a dual-boot windows partition for the first time in years, but however keen to blame this I don't see any obvious correlation...

Problem is as the heading - I start emacs successfully, then do M-x gnus. The nice logo shows up, but keeps me gazing at it while nothing seems to happen and I have to kill the process from the terminal.

I am running a customised F17 LXDE system with emacs 24.1.1 and used NoGnus (version unknown...). When the problem occured, I recalled seeing a "warning: package gg-gg is obsolete", so I removed my gnus and fetched the latest version from git. Attempting ./configure and make, this freezes just after building compface.el, so I just used the .el files. Gnus still froze on startup. So I removed all custom gnus to fallback to the distro version of gnus (5.13). Gnus still freezes on start. Believing the issue might be in some corrupted file, I removed all gnus customisation in the emacs init file and renamed ".gnus.el, newsrc.eld, News, and Mail" believing this should use defaults for everything. Still freezes. Final attempt using --no-server option, still freezing.

I have no idea where to start to get some traces or ideas how to fault find from here, and any ideas will be /very/ appreciated! As Gnus is my primary mail reader, and filter, there's no way to keep up with any mailing lists - please wide reply to my secondary e-mail as well... 

It is possible I have botched my system in other ways by fiddling with Windows, virtualisation and what not, but everything else works fine.

Cheers,

Johnny

In my experience, Gnus hanging at the startup screen can often be the
result of network issues, so I'd probably start there before I went too
far into messing around with Gnus itself. I'd firstly try connecting
into the mail server from a terminal, if that succeeds I'd then move
towards Emacs itself and check if it can see the network /
mailserver. Don't forget to try starting Emacs without any init file too
(ie. emacs -Q), as problems can be hidden there.

HTH.

Kind regards,
ian

First, this is too much suspicious. You're saying that compilation
process file blocks? I'd start to resolve this.
If you run top, is an emacs process taking all the CPU power or
something like that?

In addition to what has been suggested, you can try killall -s SIGUSR1
emacs, which will cause emacs to go into debug. This can work even if
C-g does nothing.

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

I just hit the same problem as well, after moving to MaGnus
0.6. Started using the same workaround as Johnny described, but
interested in finding out the right solution.

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 get the new one.

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])
  gnus-article-stop-animations()
  gnus-article-setup-buffer()
  gnus-article-prepare(830 nil)
  gnus-summary-display-article(830)
  gnus-summary-next-page(nil)
  call-interactively(gnus-summary-next-page nil nil)

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)
