Subject: 24.5; gnus/nnimap: ticked messages not getting marked as read

[This message was originally sent to ding <at> gnus.org.  There was some
followup discussion on 2016-2-6 on that list.]

I have a couple different systems that I use to connect to an IMAP
server.  I've noticed that messages that I had read--or at least marked
as read--using Gnus on system A sometimes show up as unread using Gnus
on system B.  I've finally tracked it down to this scenario:

- a message is unread and flagged (ticked) on the IMAP server.  Gnus
  shows it and the next message in the summary buffer as ticked.  (I'm
  not sure that status of the second message is critical for reproducing
  the problem, but it seems to help.)
- in the Gnus summary buffer, I type "d" for the first message.  The
  message is marked "r" in the summary buffer, as expected.
- I exit the summary buffer and type "s" in the Group buffer
- I check the folder using Thunderbird; it shows the first message as no
  longer flagged, but it's still shown as unread.

I expect the first message to be shown as read ("seen").

This is with Emacs 24.5.

With the debugger I captured the following stack trace while exiting the
summary buffer:

    Debugger entered--entering a function:
    * nnimap-send-command("UID STORE %s %sFLAGS.SILENT (%s)" "257948" "-" "\\Flagged")
      nnimap-request-set-mark("INBOX" (((257948) del (tick))) "beehive")
      gnus-request-set-mark("nnimap+beehive:INBOX" (((257948) del (tick))))
      gnus-update-marks()
      gnus-summary-update-info()
      gnus-summary-exit()
      call-interactively(gnus-summary-exit nil nil)
      command-execute(gnus-summary-exit)

I didn't notice any calls to set the Seen flag.

I tried figuring out what's going on in gnus-update-marks, but it's a
bit confusing, because there's both a gnus-newsgroup-seen list and a
gnus-newsgroup-unseen list.  Though this bit of code seems odd:

	(when (eq (cdr type) 'seen)
	  (setq list (gnus-range-add list gnus-newsgroup-unseen)))

Is it really adding seen messages to the unseen list?

I think I understand what's going on.  In Gnus, there's no such thing as
"ticked and unread": Everything that's \Flagged in the IMAP server
becomes read in Gnus.  So when you remove the tick (i.e., \Flagged),
Gnus will propagate that change to the IMAP server, but since it thinks
that nothing has changed WRT readedness, it doesn't send that
information to the server...

I'm not sure what the best way to fix that is...

I now made nnimap update readedness when tickedness changes, which I
think should do the trick.
