Saving .newsrc upon *Summary* exit

Saving .newsrc upon *Summary* exit

[Paul Jarc]

Is it appropriate to add gnus-group-save-newsrc to
gnus-summary-exit-hook?  Or is that hook called at a bad time for
saving?

I prefer gnus-dribble-save instead.

It gives me the same effect, but it's much quicker.

I think it is OK. If not, please post your solution.

I haven't had any problems so far.  Now, since I've gotten into the
habit of not leaving *Summary* buffers hanging around, I can leave one
Gnus running and safely run a second one in a second Emacs (on the
same machine, using the same account, .emacs, etc.).  The first one
will have saved my newsrc, so the second one will see something
consistent and up-to-date when it starts, and when I get back to the
first one, I immediately quit and restart Gnus to pick up the changes
made by the second one.  Quitting won't clobber those changes because
the first Gnus thinks newsrc is already saved.

This sounds dangerous.  Why don't you do M-x gnus-slave RET for the
second one?

Yes, it sounds that way, but I don't think it is.  Anyway, I'm only
using nntp and nnmaildir, and nnmaildir tolerates even less
synchronized concurrency.  So I'm not risking much.

Mostly because I didn't know about it.  But reading the manual - what
happens if I run a slave, quit from it, and then run a slave again
without touching the master?  Will the second slave notice the changes
from the first?  With my way, it will, and that's what I want.

Yes, it does for me with nntp, nnml and nnimap backends.

I'm not sure.  Maybe you have to `g' in the master.  I've never used
slaves.  But if it works for you...

I've been doing it for a while, though instead of saving every group (which
is slow) I programmatically save every five groups exited, like so:

(add-hook 'gnus-startup-hook 'rat:gnus-startup-hook)
(defun rat:gnus-startup-hook ()
  (setq rat:gnus-selected-newsgroups 0)
  (setq rat:gnus-incremental-save-newsrc t)
  (setq rat:gnus-incremental-save-newsrc-threshold 5)
  )

(add-hook 'gnus-save-newsrc-hook 'rat:gnus-save-newsrc-hook)
(defun rat:gnus-save-newsrc-hook ()
  (if rat:gnus-incremental-save-newsrc
      (setq rat:gnus-selected-newsgroups 0)))

(add-hook 'gnus-exit-group-hook 'rat:gnus-exit-group-hook)
(defun rat:gnus-exit-group-hook ()
  (if rat:gnus-incremental-save-newsrc
      (progn
	(setq rat:gnus-selected-newsgroups (+ rat:gnus-selected-newsgroups 1))
	(if (> rat:gnus-selected-newsgroups
	       rat:gnus-incremental-save-newsrc-threshold)
	    (gnus-save-newsrc-file)))))
