Crashing Emacs and unfinished drafts

Crashing Emacs and unfinished drafts

[Kai Großjohann]

When Emacs crashes while I'm composing a message in Gnus, I expect
the associated auto-save file to appear in the nndraft:drafts group.
It happened to me just a couple of minutes ago.¹  A file
~/News/drafts/drafts/#42#, say, was left behind.  However, Gnus does
not recognize this file.

After `mv #42# 42', all is dandy and Gnus sees the draft.

So, we have two alternatives:

(1) Have Emacs auto-save into ~/News/drafts/drafts/42 rather than
    ~/News/drafts/drafts/#42#.

(2) Have nndraft.el grok the #42# style filenames.

Or should I have done a M-x recover-session RET before starting Gnus?
But Gnus deals automatically with its ~/.newsrc auto-save file,
doesn't it?

Crashing Emacs and unsaved nnfolders

Similar problem.  I use nnmail-expiry-target to send some things to
nnfolder groups for archival.  Those files are appended to in memory
and saved when gnus quits.  They are not saved when I hit "s" in
*Group*.  (Problem 1.)

If Emacs should crash before I quit Gnus, Gnus uses the last-saved
version of the file, and loses anything which had been modified in the
autosave.  

Given Gnus' ability to handle other unsaved files (like newsrc) it
would be nice if it would handle these, but it would also be nice if
it would save them when I hit s.

You can try the attached patch (not in the CVS repository).  The
drawback is that Gnus has to save the entire nnfolder file for each
expired article.

I was afraid you'd say that.  That's bad.  Very bad.  One reason I use
nnfolder is so I can have gzipped nnfolders (I have 134MB already,
gzipped) and regzipping a 9MB file every time I expire a message
(about a 100 messages a day in that group) would quickly make me hate
life.  8^)

How about just making it save when you do gnus-group-save-newsrc...
no, that really doesn't make sense.  How about a
"gnus-group-save-everything" which I can bind to s in *Group*?  I
guess I could just add something to gnus-save-newsrc-hook.
