I am running
NetBSD/i386 3.1ish and 4.0ish
dovecot 1.0.0 procmail delivering into maildirs
gnus from CVS head emacs 21.4
thunderbird 2 gnome mail-notification 4
configured to required SSL.
Basically everything works fine except that in gnus typing 'g' in the *Group* buffer, which is supposed to check for new mail and list the number of new messages, fails to notice new mail.
Notably, gnus does not do an UNSELECT or CLOSE when it is done with a group.
So basically the following sequence of commands
SELECT "INBOX" blah blah EXPUNGE
STATUS "INBOX" shows no unseen but really there is one
With
(setq nnimap-need-unselect-to-notice-new-mail t)gnus will do UNSELECT before STATUS, and then things work fine.
Another gnus user reports what seems like the same problem with Courier IMAP.
So, is dovecot complying with the IMAP spec here? Is there some notion of a transaction bracketed by SELECT/{UNSELECT,CLOSE}, and is that using something like READ COMMITTED isolation so that it doesn't see messages added by other transactions?
Or should dovecot be not relying on cached state and revalidate the mailbox on STATUS, even if it is already SELECTED?
Further, is it the group's opinion that a well-behaved client would UNSELECT or CLOSE when the user takes an action that indicates being finished with a mailbox? Or is it reasonable to leave a mailbox SELECTed as an optimization. It seems that for Thunderbird, etc., the user sits in INBOX with IDLE, but with gnus I tend to be in *Group* with no mailboxes selected.
