If I ssh to a remote server and start Emacs and my ssh connection is severed
sometime thereafter, causing the remote emacs process to be terminated with
SIGHUP, the auto-save-list-file-name file is deleted. I find this very
undesirable. If there's an option to change this behavior, I can't find one.
The Emacs manual says this about 'auto-save-list-file-name':
When Emacs exits normally, it deletes this file; if Emacs crashes, you
can look in the file to find all the auto-save files that might contain
work that was otherwise lost. The recover-session command uses this file
to find them.
Older versions of Emacs apparently had a different definition of "when Emacs
exits normally" compared to Emacs 26.x. Emacs 21.x, for example, does not
delete the auto-save-list-file-name file when the ssh connection is severed
and a remote emacs process is killed with SIGHUP.
In GNU Emacs 26.3 (build 1, x86_64-pc-linux-gnu, X toolkit)
of 2019-11-19 built on heabox
Windowing system distributor 'The X.Org Foundation', version 11.0.12004000

Emacs deletes auto-save-list-file-name upon SIGHUP because it performs
auto-save. Since auto-saving was done, what would be the purpose of
keeping auto-save-list-file-name? That variable is only for when
auto-saving wasn't performed on exit.

Well, that's not the only thing that file is good for. For decades, I have
used the auto-save-list-file-name file to re-open all the files I had open in
the terminated Emacs process when my remote connections are severed. It's
been abundantly useful over the years. It's a shame to lose such
functionality. Just my two cents.
Regards,
Ed

Have you ever tried desktop-save-mode? Perhaps that would be a good
fit for your use case.
Best regards,

Thank you for the suggestion, Stefan. I've looked at desktop-save-mode in the
past, but I haven't tried it. From what I recalled, it seemed to save and
restore things which I don't really want restored (like variables?!), and I
think it only works with a single session. But maybe I can fix that by
changing the desktop-save-mode save file on a per-host basis. I'll look into
it further.
I still don't think the auto-save-list-file-name file should be deleted on
SIGHUP, but I won't be offended if you close this bug as "won't fix" or some
such, assuming you all disagree.
Regards,
Ed

You could try customizing `desktop-globals-to-save' and
`desktop-locals-to-save' to match your needs.
For different sessions, you could look into `desktop-dirname'.

I think this sounds like a wontfix, indeed. So I'm closing this bug now.
If you find that any features you need for your use case is missing from
desktop.el, I would encourage you to send feature requests to this list.
