Finally I got a novcache:
,----[ gnus.el ]
| ;;; Experimental Gnus setup
|
| (setq gnus-select-method '(nntp "news.gmane.org"))
| (setq gnus-secondary-select-methods
| '((nnimap "localhost"
| (nnimap-address "localhost")
| (nnimap-server-port 993)
| (nnimap-stream ssl))))
|
| (setq nnimap-nov-is-evil nil)
| (setq gnus-cache-enter-articles '(ticked dormant unread read))
|
| (setq org-gnus-nnimap-query-article-no-from-file t)
`----
Now the strange thing is that the novcache file in ~/News/overview is
100% identical to .overview in ~/News/agent
,----
| dmaus@t41 ~/News % md5sum overview/nnimap/localhost/INBOX/1280089306/novcache agent/nnimap/localhost/INBOX/.overview
| b4a78e25a064f0c260f76080a00991cd overview/nnimap/localhost/INBOX/1280089306/novcache
| b4a78e25a064f0c260f76080a00991cd agent/nnimap/localhost/INBOX/.overview
| dmaus@t41 ~/News %
`----
Anyway: `nnimap-retrieve-headers-from-file' does not work as expected.
First, it requires the group parameter without backend and server
prefix (e.g. "INBOX" instead of "nnimap+localhost:INBOX".
Second it would return a cons (min-UID . max-UID). That wouldn't help
us, would it?
Third and amazingly my novcache seems to be corrupt right after
creation: `nnimap-retrieve-headers-from-file' does not get the maximum
UID but reads "INBOX" (?!) -- A string that looks kind of a header
information for nov -- and not "18753" what is the highest UID in the
mailbox.
Last line of the cache:
(it's a local copy of wanderlust general newsgroup accessed via IMAP)
