A Debian user has reported a crash with Emacs 28. I'm attaching the

patches are relevant.

Signal 1 is SIGHUP, AFAIU. Why should Emacs receive SIGHUP in the
middle of GC, I have no idea. Maybe ask the user what was he doing at
that time. E.g., could that be a remote Emacs session?
Other than that, I don't see what can be done with this data: this is
an optimized build, and there's no real data in the backtrace to begin
considering why would SIGHUP happen. Sorry.

Hello Vincent,
Upstream says there isn't enough information in the backtrace to say
anything helpful about this. Could you take a look at
<https://debbugs.gnu.org/58956> and consider supplying more information
over there, please?
Also, are you able to reproduce this with 'emacs -q' (not -Q)?
Currently we have no way to reproduce this, and you're the only person
who's seen anything like this, so we'll probably have to move the
severity back down to 'important'.

No, it is on my local machine.

This is not reproducible with "emacs -q".
I can reproduce it in a firejail private directory[*] (so that the
behavior doesn't depend on my own config files), where there is no
.emacs file. There is a .emacs.d directory with just a eln-cache
subdirectory:
zira% ls -la .emacs.d

I run emacs, and quit it immediately. The generation of the core dump
is almost 100% reproducible. Ditto with "emacs -nw".
But note that the bug is also reproducible without firejail, but
harder to reproduce.

So how come Emacs gets a SIGHUP? This is the crucial detail that is
missing here. Basically, if SIGHUP is delivered to Emacs, Emacs is
supposed to die a violent death.

Wait, you mean the crash is during exiting Emacs? That could mean
Emacs receives some input event when it's half-way through the
shutdown process, and the input descriptor is already closed.
But the backtrace you posted shows SIGHUP during GC, which is AFAIU a
very different case.

I suspect the SIGHUP comes from Emacs itself. According to strace
output, the only processes started by Emacs are "/usr/bin/emacs"
(there are many of them). I don't see what other process could be
aware of the situation. Unfortunately, I couldn't reproduce the
issue with strace (I suspect some race condition).

For this test, yes. In general, I don't know.

Note that the process that crashes is not the Emacs I started,
but a subprocess run by Emacs itself, since it has arguments like
"-no-comp-spawn --batch -l /tmp/emacs-async-comp-url.el-FGov4z.el".
However, it also happened that the Emacs I started immediately
crashed (this occurred only once, though).

Andrea, could you please look into this? The SIGHUP could be because
the parent process exits, but that shouldn't cause a crash in the
sub-process that performs native compilation?
Thanks.

Hi Eli,
AFAIU the Emacs subprocess we use to compile should behave like a
regular Emacs.
Now, the only option that comes to my mind is that libgccjit (being
strictly derived from the GCC codebase) might be registering a signal
handler of some kind that alters the behaviour we expect. But if this
is the case we should find trace of it the strace, or we can use gdb
setting a break point into 'signal' as well to check.
Indeed if this theory is true I think should be classified as a
libgccjit bug.

Basically, you are saying that if the sub-process that runs
async-compilation gets SIGHUP, it should abort and dump core, like a
normal Emacs session does, right?
The backtrace posted to the Debian bug tracker, here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=1017711;filename=gdb.txt;msg=5
indicates that Emacs was in the middle of comp-copy-insn which was
called from comp-fwprop. Then Emacs performed GC, and SIGHUP was
received during GC. IOW, we were in our Lisp code, not in a libgccjit
code, when the signal arrived.
Another backtrace, posted here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=1017711;filename=gdb.txt;msg=45
tells a somewhat different story: it doesn't show Emacs in the middle
of a native compilation, but just inside substitute-command-keys that
was called from command-line.

I don't think it's true, see above.
Paul, can you help here, please? We need to establish what is the
source of SIGHUP in these cases. "These cases" mean, AFAIU, the
situations where Emacs launched an async subprocess to do native
compilation (which is another Emacs process in a --batch session), and
the parent Emacs session is terminated by the user before the async
compilation runs to completion. Would the child Emacs process get
SIGHUP in this scenario? If yes, then I think we should treat SIGHUP
differently in non-interactive invocations: instead of dumping core,
we should catch the signal and exit with a non-zero exit status.
Does this make sense?
Andrea, if we do the above as I suggest, is there any cleanup that we
need to do before exiting? For example, what if the subprocess that
does the async compilation already started writing the .eln file when
the signal arrives? What do we do today when the parent interactive
Emacs is terminated by the user?

Sorry I missed those traces. Okay so for both cases if libgccjit is not
involved the behaviour of Emacs here is just the plain one and should
not be related to native compilation. It's just that native compilation
makes it more likely to be identify this condition.

I think we have no special handling for this case, so yeah we might
leave some traces of the compilation. Other than the .eln we should
also remove the lisp file we write to be loaded by the async compilation
process. I'm not sure where and how would be best to handle all of this
tho.
Best Regards
Andrea

Hard for me to say. It's a messy area, with kernels (and Emacs itself)
sending SIGHUP on various whims.
Does the attached patch fix things? It builds on your commit
190a6853708ab22072437f6ebd93beb3ec1a9ce6 dated 2020-12-04; I don't know
why that earlier patch was installed, but it would seem to apply to
SIGHUP and SIGTERM as well as it applies to SIGINT.

But is it possible for a program like Emacs to get SIGHUP in such a
situation, or is that highly improbable? We have standard streams of
the inferior Emacs process connected via PTYs to the parent process, I
believe -- does that deliver SIGHUP or SIGPIPE when the parent exits?

I was trying to be conservative, that's all. I'm okay with doing the
same for SIGHUP. Vincent, can you try this patch, please?

It depends on the OS and the app that invokes Emacs and how that app
itself was invoked. It's a hairy area.
On a POSIX platform it's certainly *possible* for Emacs to get SIGHUP in
that situation, because a user can invoke the shell command 'kill -s HUP
P', where P is the process ID of the inferior Emacs. Whether it's
*likely* is a bit harder to say. I ran a few little experiments on
Fedora 36 and Ubuntu 22.10 and found SIGHUP being sent in a few
situations and not others and didn't have the time or patience to suss
out exactly why or when.

Thanks. The scenario that is of primary interest in this case is the
following:
. user starts Emacs
. Emacs loads some Lisp package and as results starts a subordinate
Emacs process in batch mode to native-compile the loaded Lisp
. user exits Emacs
My question was whether in this scenario, since the parent Emacs
exits, the child Emacs can get SIGHUP, simply because its parent
exited and the read end of the PTY no longer exists.

Yes, my sense from the few experiments I tried, is that it's a plausible
scenario, though I never observed it actually happening for Emacs doing
a subprocess compile.

OK, thanks. So I hope your suggested patch will solve this issue.

Hello Vincent,
Are you able to test the patch? Let me know if you need help getting an

No further comments, so I've now installed this on the master branch,
and I'm marking this bug done.
Thanks.

Sorry, I couldn't test it yet, first because of an uninstallable
package needed for the build because I couldn't upgrade libc6 yet
and I couldn't get the previous version from snapshot.debian.org
(bug 1023540). Now that I could upgrade libc6, I'll be able to
test when I have some time, but perhaps not before the week-end.

Okay, do let me know if I can help -- this is blocking Emacs from migrating.

I've rebuilt the packages with the patch and couldn't reproduce
the bug yet. So it may be the correct fix.
