Synchronizing offlineimap maildir between several computers

Synchronizing offlineimap maildir between several computers

[Julien Cubizolles]

I'm using offlineimap to get Maildir copies of several IMAP accounts
from Gnus. I need to work from two different computers. At the moment,
I'm synchronizing the .gnus.el file between the 2 computers through
unison and relying on offlineimap running on the 2 computers to have the
Maildirs synchronized with the remote IMAP servers of my mail providers.

When I switch computers, I run unison, start Gnus which calls
offlineimap.el through a hook. It's basically working fine except that
until offlineimap has finished the synchronization, the .gnus.el data is
out of sync with the maildir so I get mostly starred groups.

I'm thinking about having Gnus call unison and offlineimap as
gnus-before-startup-hook but before I'm messing with it I'm curious
about what other solutions you have come up with.

I run mbsync (the equivalent of your offlineimap) in the shell, and when
that's done I run Gnus :)

You're right, sometimes I should give Emacs a break and run some process
outside of it :-)

Last time I tried to do this I ran into problems because unison does not
correctly support hard links, but some features of maildir seem to use
them.

I don't synchronize the maildir through unison, only the .gnus.el file
so I never ran into this problem so far.

Nah, just in the background:

(global-set-key "\C-Cg" '(lambda () (interactive)
                           (async-shell-command "offlineimap.py")))

And that *is* in a separate process outside of it; just starting it from
the right init system!

How do you cleanly kill offlineimap ?

You don't to run it as a daemon.  IE, you can run a single invocation of
it to check the required imap folders and then quit.

Also, it turns out that C-c C-c seems to interrupt it nicely.
