Gnus-slave forgets news marks, remembers mail marks

Gnus-slave forgets news marks, remembers mail marks

Hi.

On a typical day, I check my mail and news from a half-dozen or more
different computers. Each time, I open an ssh connection to my home
pc, bring up a new instance of emacs, and run `gnus-slave`. I also
have a long-running emacs process on the same pc, which is running
gnus (rather than gnus-slave).

Gnus-slave does a fine job of remembering my mail marks (e.g., if I
mark a message as read, gnus remembers that it's been read).

Not so with news: if I mark a news article as read in gnus-slave,
close that instance of emacs, then (later) launch another gnus-slave
session, the article still shows up as unread.

Is there any way to eliminate this behavior? Perhaps by signaling the
long-running process to read the slave newsrcs? 

I'm also curious as to why it doesn't affect mail -- only news.

Thanks in advance,

--Joe

Also gnus-slave shows news groups as having unread articles in groups
where I have previously (before starting the emacs with gnus-slave)
read all articles in the "main" gnus. I always respond "yes" to the
question of whether to read the gnus autosave file.

You could run gnuserv on the long-running process and then eval the
right Lisp expression using gnudoit.  (Not sure if emacsclient as of
Emacs 21.3 groks the -e option.  If it does, you can also use that.)

nnml groups store their marks in the .marks file.  But there is no
corresponding file for nntp groups.  Maybe that's the reason.

Something like this?

(add-hook 'gnus-slave-mode-hook 'ask-master-to-update-newsrcs)

(defun ask-master-to-update-newsrcs () 
  (message "Telling master to read slave newsrcs.")
  (shell-command "gnuclient -q -batch -f gnus-master-read-slave-newsrc")
)
