Keeping multiple imap-and-nntp-based gnusae in sync

Keeping multiple imap-and-nntp-based gnusae in sync

[Lloyd Zusman]

I'm using a very recent version of Oort to access my imap and nntp
servers on a central host.  I have three installations of Oort on three
separate machines, each Oort instance configured identically to point to
the same imap and nntp servers.  I do this because during the course of
a day, I work from each of these three machines.

All this works fine, except for the inconvenient fact that my marks and
"read" statuses are local to each machine.  Therefore, I find myself
re-reading and re-marking messages when I go from machine to machine.

Has anyone invented a procedure for sync-ing marks and article statuses
across multiple versions of gnus?

Yes, I know that I can use rsync or something similar to keep the
appropriate files in sync on the various machines ... once I figure out
which files to sync up and not to sync up (any hints?).  But before I
re-invent the wheel, I'm wondering if someone else has tackled this
problem already, and if perhaps there's some existing software I can use
for this purpose.

Thanks in advance.

For IMAP, the server should keep all state, for NNTP you have to sync
.newsrc.eld or similar.  If the IMAP server doesn't support
client-specific flags, Gnus specific flags (e.g., expired and dormant)
won't be synced either.  Read flags should definitely be synced
though.  Does it help to press M-g before entering a group?  Did you
mean they weren't synced in the group buffer (unread article count),
or in the summary buffer?  The former is a known bug, but the latter
should work.

Yes, I was confused by the unread article count in the group buffer.
The actual read and unread articles indeed show up properly in the
summary buffer.

With regard to the gnus-specific flags (expired, dormant, etc.) and the
nntp state: is it sufficient that I sync `.newsrc.eld', or do I have to
sync other items, as well? ... what about `.newsrc' (without the `.eld'
suffix)?

Thanks for your help.

I use unison <http://www.cis.upenn.edu/~bcpierce/unison/> to keep
(most of) my home directories in sync.  For gnus, I'm pretty sure that
keeping .xemacs/*, .gnus, .newsrc* and .Mail and .News directories in
sync works fine though it may be overkill (I exclude the .News/agent
and its subdirectories to save time, for example).

Ok, that's normal.

.newsrc.eld should be enough, although you might want to be careful
when syncing it as it contains other stuff as well.

I used to do that, and ~/News/, ~/Mail/, ~/.nnmail-cache, ~/.newsrc*
are sufficient (with the default filename settings).

But I keep wondering whether there might be another
solution...  Could you log in to a central host and run Gnus from
there?  For running two Gnusae on the same host, M-x gnus-slave RET
is your friend.

No, I can't log in to the central host from the remote machines. :(
All I can do is get remote IMAP, NNTP, rsync, etc. connections.  If I
could log in, then I would have done that, and I wouldn't have needed to
ask this question in the first place. [sigh]

Also gnuserv/gnuclient and screen are very useful in this regard.

Interesting. I guess you run two separate emacs processes?
Or is there a way to connect to the first emacs process
without starting a new one?

Where can I find more information about this? I looked in
the gnus and emacs info files, but there was no mentioning
of these.

With Emacs running under X11, you can install gnuclient and then use
gnudoit to have the first instance execute (make-frame-on-display
...).

XEmacs running under X11 can also create a new frame on a TTY.

Google is your friend.  They are not part of Emacs.  (But they are
included with XEmacs I think.)

Screen is a GNU utility, independent of Emacs.  It's very useful;
quick tutorial:

^A^D = detach current screen
screen -r = get back to current screen
screen = start new screen session

You can even forcibly detach a screen from another terminal and attach
it to yours.

You can get Gnuserv for GNU Emacs in

http://meltin.net/hacks/emacs/

it's available in XEmacs by default, I believe.  The GNU Emacs Gnuserv
package is a hack but it works fine for me.

Actually the Google hits were pretty inaccurate.
http://meltin.net/hacks/emacs/ didn't show up when I looked.  The
XEmacs gnuserv packages were also showing up a lot, confusing matters
further.

Also rather nifty is elscreen, which is a screen-type package for
Emacs.
