Subject: 25.2; Emacs does not ask to save modified files when shutting down OS
Date: Mon, 10 Jun 2019 20:31:38 +0200

[Message part 1 (text/plain, inline)]

Hi there,

1. Open Emacs
2. Open some file in a buffer (C-x C-f)
3. Edit the buffer, DON'T save it to file
4. Shutdown computer (e.g. Ubuntu shutdown)
5. Start it back up again
6. Open the same file again
7. Look for the change you made... it's not there

The file is not saved during OS shutdown, nor is there any complaint
from Emacs in this situation.  It is about to lose data... It should
complain!

Regards,
Johan

Does any editor complain in such a situation?
It would mean a user process could block a shutdown, which seems unlikely.

Anyway, this is the kind of thing auto-save files are for.

I've got an Apple machine at work, and when I try to reboot it, there
are frequently user processes that stop the process.  It's really
annoying.

So it's available on some systems...

I don't think Emacs wants to do that, but it could, like, listen to dbus
messages about being shut down and try to autosave some buffers, for
instance...  Perhaps?

Shutdown sends SIGTERM, so Emacs could (auto)save on receipt of that
signal (if it doesn't already do so?).

And SIGTERM triggers kill-emacs, which runs kill-emacs-hook, so if you
want some (unprompted) saving, you could do it with that hook.

AFAIU, we don't: we just call kill-emacs.

But how to distinguish SIGTERM due to system shutdown and SIGTERM when
the user triggers the signal?

I don't think one can, or should.

Is this therefore a wontfix?  We already have auto-save files, as Glenn
pointed out.

(FWIW, It seems to me that we would need a solution for this on a
GNU/Linux level before we can do something in Emacs.  And AFAIK there is
no way for a user level program to halt a system halt.)

I guess so.

I think we support the session management protocol for this, see
xsmfns.c.

Thanks.  I'm therefore closing this bug report now.
