auto-save files, why?

auto-save files, why?

[Stephen Zander]

Just idle curiousity but why would I be regualrly getting the 'auto-save
file exists, do you want to load it?' message?  I've answered no (to
my peril) previously, so now religiously say yes.  I'm just wondering
why it exists at all, instead of being rolled into ~/.newsrc.eld.

BTW, yes, I am exiting gnus cleanly.

What if I do "s" and exit emacs, is that same as doing "q" in Group
buffer?

Yes.  I haven't checked the code, but judging by experience, pressing
`s' and exiting Emacs is considered a clean exit from Gnus.

Does that matter?  I mean, if you don't do any Gnusae operation
between pressing `s' and `C-x C-c', no new stuff will get written to
the dribble buffer.

Are you sure?  Once you save the buffer, the autosave should be
removed.  If the buffer remains unchanged up to the point when you
press `C-x C-c', everything should work fine.

In fact, I've exited Gnus using `s' followed by `C-x C-c' many times
(for various reasons), and I've never seen the auto-save file being
generated as a result.  But then again, I am not 100% sure what
strategy Gnus uses for autosaving `.newsrc', so I may be missing
something.

And this explains my original problem; I was dropping back to the *Group*
buffer but not quiting from there.... thanks for the info!

The idea of an "open buffer" is a semantic null.  A file is opened,
read, and closed.  What matters thereafter is whether the buffer
containing that file's contents changes.

Once modified, and then once the file is saved (so changes have been
sync'd to disc), auto-saving is off, unless the contents of the file
are then modified again.  If no further changes are made, exit from
Emacs without specifically exiting Gnus means no autosave file is
created as Emacs departs this life.

Existence proof: In another XEmacs on another system, running Gnus, I
backed out to *Group*, hit `s' to save current contents, and the `C-x
C-c' to exit XEmacs.  No autosave was created.

It fails to run the `gnus-after-exiting-gnus-hook'.  That makes a
difference for me because I run stuff on both that hook and the
`gnus-startup-hook'.
