Re: message registry for Gnus

[Ted Zlatanov <tzz@lifelogs.com>]

I'm not sure how to deal with this issue.  The (gnus-data-header)
information about an article from gnus-data-list is available for the
registry when I catch respooling, moving, copying, expiring, and
deletion of articles.  Spooling, however, only gives me the article's ID:

(from nnmail.el)

(defun nnmail-cache-insert (id grp)
  (run-hook-with-args 'nnmail-spool-hook 
		      id grp)
...


Is the data header for the article available somehow at the point of
cache insertion in nnmail.el?  I would really like to have that header
available for message analysis at that moment, not later when the
article is copied/moved/etc, so the registry interface is consistent.

Also, to save a hashtable, it seems like I have to convert it to an
alist and put that in a file, and convert the other way when I want to
load from a file.  Is there an easier way?

Thanks
Ted
