Well, using `nnimap-retrieve-headers-from-file' would work because it
loads the cache into `nntp-server-buffer'. But it turned out that my
problem with the garbled cache is a bug in this function: It doesn't
erase the buffer before inserting the cache file and the buffer is not
empty (bug report filed).
So we need our own function. A slight modification of yours:
--8<---------------cut here---------------start------------->8---
(defun org-gnus-nnimap-get-article-number (group server message-id)
(with-temp-buffer
(let ((nov (nnimap-group-overview-filename group server)))
(when (file-exists-p nov)
(mm-insert-file-contents nov)
(set-buffer-modified-p nil)
(goto-char (point-min))
(catch 'found
(while (search-forward message-id nil t)
(let ((hdr (split-string (thing-at-point 'line) "\t")))
(if (string= (nth 4 hdr) message-id)
(throw 'found (number-to-string (nth 0 hdr)))))))))))
--8<---------------cut here---------------start------------->8---
- the message-id might also appear in a in-reply-to oder references
field
- use a temp buffer to avoid possible confusion for Gnus
(e.g. content of nntp-server-buffer changed outside Gnus)
