Merged trunk to elmo-imap4-compliance

* elmo-imap4.el (elmo-folder-delete-messages-plugged): Use smarter
mechanism to expunge messages.

If there are already messages in the mailbox with the \Deleted flag
set, use following algorithm to delete only our messages:

If `elmo-imap4-use-uid' is non-nil, and the server supports the
UIDPLUS extension, use the UID EXPUNGE command.  Otherwise temporarily
remove \Deleted flag, call EXPUNGE, and restore the flag.

If `elmo-imap4-use-uid' is nil, use old mechanism and prompt the user.

elmo-imap4.el (elmo-imap4-session-deselect-mailbox): New function.
Leave selected state without causing silent EXPUNGE.
(elmo-imap4-folder-status-plugged, elmo-folder-rename-internal): Use
function.

* elmo-imap4.el (elmo-imap4-mailbox-size-update-maybe): Ignore
EXPUNGE responses.
(elmo-imap4-mailbox-size-update-maybe): Use latest EXIST or RECENT
response value.

If the mailbox size changes due to EXPUNGE by another client the
server will inform us with a EXISTS or RECENT response.  If the
expunging didn't change the mailbox size the server might not do so.

If there are more than one EXISTS or RECENT response, use the latest.

2010-07-02  David Maus  <dmaus@ictsoc.de>

    * elmo-imap4.el (elmo-folder-next-message-number-plugged): Close
    mailbox before calling STATUS if selected.  If
    `elmo-imap4-use-select-to-update-status' is non-nil, do the opposite.

2010-07-02  David Maus  <dmaus@ictsoc.de>

* elmo-imap4.el (elmo-imap4-folder-status-plugged): Remove usage of kill file to
adjust message counter.

2010-07-02  David Maus  <dmaus@ictsoc.de>

* elmo-imap4.el (elmo-server-diff-async): Remove.  Unused luna
method.
(elmo-imap4-folder-status-plugged): Close mailbox before calling
STATUS if it is selected.  If
`elmo-imap4-use-select-to-update-status' is non-nil, do the
opposite.

* elmo-imap4.el (elmo-imap4-mailbox-selected-p): Fix typo.

* elmo-imap4.el (elmo-imap4-mailbox-selected-p): New macro.
Return non-nil if mailbox is selected in session.
(elmo-imap4-session-select-mailbox): Use macro
`elmo-imap4-mailbox-selected-p'.
(elmo-folder-exists-p-plugged): Dto.
(elmo-folder-check-plugged): Dto.
(elmo-imap4-folder-diff-plugged): Dto.

* elmo-imap4.el (elmo-imap4-mailbox-size-update-maybe): Use
simpler method to count expunged messages.
(elmo-imap4-folder-diff-plugged): Use NOOP and SEARCH when called
for selected mailbox.

Remove usage of kill file to adjust message counter.

The kill file contains cons' with ranges of UIDs that are considered
'killed', i.e. hidden from user's view.  But these ranges cannot be
used to adjust counter of total messages in a IMAP4 mailbox: A range
of (1 . 100) does not necessarily refer to 100 messages.  E.g. if
there are 100 messages in the mailbox with UID ranging from 1 to 100
and you delete the first message, the range (1 . 100) refers to 99
messages.

* elmo-imap4.el (elmo-imap4-mailbox-size-update-maybe): Build list of
  expunged messages only when response contains expunge.

Record mailbox size changes of selected IMAP4 mailbox.  Required to
comply with RFC 3501, section 7.3 and 7.4.1.

Note: EXPUNGE response is recognized to decrement number of
messages in mailbox only.

imap4-compliance'.

extensions.
