nntp and nnimap disconnect and take forever when emacs is idle

nntp and nnimap disconnect and take forever when emacs is idle

[Divya Ranjan]

Hello,

Does anyone else also experience this, when they’ve left their Emacs or just gnus idle for sometime, it disconnects from the server, whether nntp or nnimap, and then when you open a group that’s requesting that server, it takes forever to load. Is this one of those things that you have to swallow with Gnus, or is there some hack?

Regards,

Had the same thing. Just set low connection timeout to quickly renew
connections:

#begin_src emacs-lisp
gnus-select-method '(nntp "xxx"
                    (nntp-open-connection-function nntp-open-tls-stream)
                    (nntp-port-number 563)
                    (nntp-address "xxx")
                    (nntp-connection-timeout 5))
#end_src

At least concerning nntp this sounds like bug#52735 (which I continue to
experience); see also the thread beginning at
<https://lists.gnu.org/archive/html/info-gnus-english/2023-06/msg00014.html>.

I use the following hack, added to my ~/.emacs.d/.gnus.el file:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defun srb-gnus-group-get-new-news (&optional arg one-level)
  (interactive "P")
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-group-get-new-news))
    (gnus-group-get-new-news arg one-level)))

(defun srb-gnus-summary-next-unread-article ()
  (interactive)
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-summary-next-unread-article))
    (gnus-summary-next-unread-article)))

(defun srb-gnus-summary-next-page (&optional lines circular stop)
  (interactive "P")
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-summary-next-page))
    (gnus-summary-next-page lines circular stop)))

(defun srb-gnus-summary-scroll-up (lines)
  (interactive "P")
  (with-timeout (1 (kill-buffer (nntp-find-connection-buffer
                                 nntp-server-buffer))
		   (gnus-summary-scroll-up lines))
    (gnus-summary-scroll-up lines)))

(define-key gnus-group-mode-map "g" 'srb-gnus-group-get-new-news)
(define-key gnus-summary-mode-map "n" 'srb-gnus-summary-next-unread-article)
(define-key gnus-summary-mode-map " " 'srb-gnus-summary-next-page)
(define-key gnus-summary-mode-map "\r" 'gnus-summary-scroll-up)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

But this is brittle and doesn't always work.  If you find a real
solution, I'd be interested to see it.

Hi, I believe this is known issue. Here's the link with the bug report:

What I do is run a 'keepalive' every 5 minutes to quickly poke
the server and maintain the connection.  You can do this with
a run-with-timer although I prefer to do it outside of emacs
with a bash script.

it's this (or it's related, or a duplicate)

I do something along those lines with the following in my gnus.el (but
it could be anywhere else):

(gnus-demon-add-handler 'gnus-demon-scan-news 15 t)

this seems to suggest that 

(setq read-process-output-fast nil)


would work?

No.
I've made test:
1. Set (setq fast-read-process-output nil) globally.
2. Commented every (nntp-connection-timeout 5) to bring back default
setting.
3. Restarted Emacs.
4. Gnus hanged on connection to news.gwene.org

Only using (nntp-connection-timeout 5) fixes this problem for me.

^^ did fast-read-process-output survive?

For me, setting this has so far kept my Gnus alive for four hours non
stop. But yes, that is just one datapoint.

You can close the connection(s) when idle. See (info "(gnus) Daemons").
