Merge from gnus--rel--5.10
Patches applied:
* gnus--rel--5.10 (patch 149-151)
- Merge from emacs--cvs-trunk--0
- Update from CVS
2005-10-27 Reiner Steib <Reiner.Steib@gmx.de>
* lisp/gnus/flow-fill.el (fill-flowed-encode-tests): Restore trailing
whitespace removed in revision 7.8. Use concatenated string to
protect trailing whitespace.
2005-10-27 Jouni K Seppanen <jks@iki.fi> (tiny change)
* lisp/gnus/nnimap.el (nnimap-search-uids-not-since-is-evil): Add variable.
(nnimap-request-expire-articles): Use it to avoid sending 'UID
SEARCH UID ... NOT SINCE' queries, for inefficient servers like
Courier IMAP ("some version from 2004"). Mostly based on similar
code in the same function.
2005-10-26 Katsumi Yamaoka <yamaoka@jpl.org>
* lisp/gnus/message.el (message-display-completion-list): New function.
(message-expand-group): Use it; make sure the Completions buffer
is modifiable.

;;; Commentary:
|
||
|
||
;; Todo, major things:
|
||
;;
|
||
;; o Fix Gnus to view correct number of unread/total articles in group buffer
|
||
;; o Fix Gnus to handle leading '.' in group names (fixed?)
|
||
;; o Finish disconnected mode (moving articles between mailboxes unplugged)
|
||
;; o Sieve
|
||
;; o MIME (partial article fetches)
|
||
;; o Split to other backends, different split rules for different
|
||
;; servers/inboxes
|
||
;;
|
||
;; Todo, minor things:
|
||
;;
|
||
;; o Don't require half of Gnus -- backends should be standalone
|
||
;; o Verify that we don't use IMAP4rev1 specific things (RFC2060 App B)
|
||
;; o Dont uid fetch 1,* in nnimap-retrive-groups (slow)
|
||
;; o Split up big fetches (1,* header especially) in smaller chunks
|
||
;; o What do I do with gnus-newsgroup-*?
|
||
;; o Tell Gnus about new groups (how can we tell?)
|
||
;; o Respooling (fix Gnus?) (unnecessary?)
|
||
;; o Add support for the following: (if applicable)
|
||
;; request-list-newsgroups, request-regenerate
|
||
;; list-active-group,
|
||
;; request-associate-buffer, request-restore-buffer,
|
||
;; o Do The Right Thing when UIDVALIDITY changes (what's the right thing?)
|
||
;; o Support RFC2221 (Login referrals)
|
||
;; o IMAP2BIS compatibility? (RFC2061)
|
||
;; o ACAP stuff (perhaps a different project, would be nice to ACAPify
|
||
;; .newsrc.eld)
|
||
;; o What about Gnus's article editing, can we support it? NO!
|
||
;; o Use \Draft to support the draft group??
|
||
;; o Duplicate suppression
|
||
;; o Rewrite UID SEARCH UID X as UID FETCH X (UID) for those with slow servers

"Mail will be split according to these rules.

Mail is read from mailbox(es) specified in `nnimap-split-inbox'.
|
||
|
||
If you'd like, for instance, one mail group for mail from the
|
||
\"gnus-imap\" mailing list, one group for junk mail and leave
|
||
everything else in the incoming mailbox, you could do something like
|
||
this:
|
||
|
||
\(setq nnimap-split-rule '((\"INBOX.gnus-imap\" \"From:.*gnus-imap\")
|
||
(\"INBOX.junk\" \"Subject:.*buy\")))
|
||
|
||
As you can see, `nnimap-split-rule' is a list of lists, where the
|
||
first element in each \"rule\" is the name of the IMAP mailbox (or the
|
||
symbol `junk' if you want to remove the mail), and the second is a
|
||
regexp that nnimap will try to match on the header to find a fit.
|
||
|
||
The second element can also be a function. In that case, it will be
|
||
called narrowed to the headers with the first element of the rule as
|
||
the argument. It should return a non-nil value if it thinks that the
|
||
mail belongs in that group.
|
||
|
||
This variable can also have a function as its value, the function will
|
||
be called with the headers narrowed and should return a group where it
|
||
thinks the article should be splitted to. See `nnimap-split-fancy'.
|
||
|
||
To allow for different split rules on different virtual servers, and
|
||
even different split rules in different inboxes on the same server,
|
||
the syntax of this variable have been extended along the lines of:
|
||
|
||
\(setq nnimap-split-rule
|
||
'((\"my1server\" (\".*\" ((\"ding\" \"ding@gnus.org\")
|
||
(\"junk\" \"From:.*Simon\")))
|
||
(\"my2server\" (\"INBOX\" nnimap-split-fancy))
|
||
(\"my[34]server\" (\".*\" ((\"private\" \"To:.*Simon\")
|
||
(\"junk\" my-junk-func)))))
|
||
|
||
The virtual server name is in fact a regexp, so that the same rules
|
||
may apply to several servers. In the example, the servers
|
||
\"my3server\" and \"my4server\" both use the same rules. Similarly,
|
||
the inbox string is also a regexp. The actual splitting rules are as
|
||
before, either a function, or a list with group/regexp or
|
||
group/function elements."
