Subject: 24.2; message-make-date returns a localized date after X restart
Date: Tue, 25 Sep 2012 16:08:04 +0200

Sorry for the cross-post to bugs <at> gnus.org, but I suspect the bug is more
related to Emacs than to Gnus, as it seems to be at C level. Or
maybe this is related to some libraries shipped by Debian.

The bug is present at least since emacs 23.2.

start emacs with emacs --daemon

start gnus to load message.el

(message-make-date)

=> "Tue, 25 Sep 2012 15:43:59 +0200"

; kill X

(message-make-date)

=> "mar, 25 set 2012 15:44:31 +0200"

; message-make-date is a two lines function:

(let ((system-time-locale "C"))
  (format-time-string "%a, %d %b %Y %T %z"))

=> "Tue, 25 Sep 2012 15:45:13 +0200"

; after the evaluation, everything is back to normal

; without evaluating it, calling (message-make-date) alone continues
; to return a localized date.

(message-make-date)

=> "Tue, 25 Sep 2012 15:45:32 +0200"

Best wishes

This is the definition of `message-make-date', so this seems rather odd:

(defun message-make-date (&optional now)
  "Make a valid data header.
If NOW, use that time instead."
  (let ((system-time-locale "C"))
    (format-time-string "%a, %d %b %Y %T %z" now)))

Are you picking up a very old version of message.el from somewhere,
perhaps?  Or are you redefining `message-make-date'?

No and no. "Library is file /usr/share/emacs/23.2/lisp/gnus/message.elc"

I run GNU Emacs shipped with Debian. GNU Emacs 23.2.1
(i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 2010-12-11 on
raven, modified by Debian.

I can reliably reproduce this bug on my box with the receipt provided.
My workaround was to put something like this in .xinitrc:

emacsclient -e '(let ((system-time-locale "C")) (format-time-string "%a,
%d %b %Y %T %z"))'

After the apparently useless evaluation, everything is back to normal.
From what I can see, the bug is deep inside the C code or related
libraries shipped by Debian, as the Lisp looks quite fine (I did some
source-diving myself).

I can reproduce it reliably with emacs 24.2 too.

; start emacs
emacs --daemon
emacsclient -c -n

; start gnus

; evaluate: everything fine
(message-make-date)
"Tue, 25 Dec 2012 17:44:53 +0100"

; kill X and leave the daemon alive
; bring the emacs back with emacsclient -c -n


; evaluate first time, here we have the broken header
(message-make-date)
"mar, 25 dic 2012 17:45:40 +0100"

(emacs-version)
"GNU Emacs 24.2.2 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2012-12-25 on universe"

; and now we're back to normal, after the first evaluation
(message-make-date)
"Tue, 25 Dec 2012 17:46:23 +0100"

(gnus-version)
"Gnus v5.13"

Please let me know if I can help in some way.

Best wishes and thanks for your awesome work.

Oh, it's that bug.  There was some talk about fixing this a few days
ago, but I don't recall what the result was.

Anybody?

Anyway, it's an Emacs bug, not a Gnus bug, so I'm reassigning back to
Emacs.

I'm pretty sure this was fixed at the time (six years ago), so I'm
closing this bug report.  If it's still present, please reopen.
