Subject: 28.0.92; crash when X server died
Date: Mon, 04 Apr 2022 17:19:57 -0400

I was in the midst of creating a new Emacs frame (C-x 5 2) when my X
server (Xwayland) died.  I’ve only been using frames on this one server,
though it looks like the methods I’m using for creating them may give me
a mix of $DISPLAY values of :0 and :0.0 in emacs and emacsclient
invocations, which Emacs may still be treating as different displays and
thus opening two connections.  This might explain trying to update
frames on one display when the other goes away.

I’m using the emacs-lucid-28.0.92-2.fc35.x86_64 package, as packaged up
at
https://download.copr.fedorainfracloud.org/results/bhavin192/emacs-pretest/
, on Fedora 35.  It looks like my use of daemon mode has fallen by the
wayside somewhere, so losing both displays means the process exits.  I
had multiple IRC (rcirc) connections open, emacs server enabled, TRAMP
in use, and at least one interactive shell subprocess on a remote
machine.

Some notable stack frames:
 #51: creating a new frame
 #41: reporting lost connection to display :0
 #28: reporting lost connection to display :0.0; no frames left, kill emacs
 #23: calling hooks registered for kill-emacs
 #18: server-force-stop
 #14: delete-process calls into redisplay
 #12: redisplay (SELECTED_FRAME) calls emacs_abort
 #8:  shut_down_emacs kills processes
 #7:  delete-process calls into redisplay
 #5:  redisplay calls emacs_abort

:0 and :0.0 are different X servers from the point of view of Xlib.
Don't mix up display names like that: it just wastes display
connections.

x_connection_closed binds inhibit-redisplay to t, so redisplay cannot do
anything interesting inside.

But this frame shows that it did try to do something, and aborted.
Unfortunately, I don't see anything interesting at line 15633 in Emacs
28.  Please build without optimizations and try to see exactly what
called emacs_abort.

Thanks.

True.

It looks like it aborted trying to do nothing ;-)

I do see something interesting (did you look in 28.0.92 sources?):

  /* No redisplay if running in batch mode or frame is not yet fully
     initialized, or redisplay is explicitly turned off by setting
     Vinhibit_redisplay.  */
  if ((FRAME_INITIAL_P (SELECTED_FRAME ())  <<<<<<<<<<<<<<<<<<<<<<<<<
       && redisplay_skip_initial_frame)
      || !NILP (Vinhibit_redisplay))
    return;

Crystal ball says something is wrong with SELECTED_FRAME, and that
causes the abort.

My guess would be that Ken's kill-emacs-hooks were called when the X
server died, and one of those hooks is unsafe, in that it causes
redisplay.  Or maybe we should refrain from calling
redisplay_preserve_echo_area in delete-process when Emacs is shutting
down due to a fatal error?

Yes, thanks.  I think the problem is that selected_frame is dead.  But
if my reading of the code is correct, x_connection_closed calls
delete_frame on all the frames on the disconnected terminal before
Fkill_emacs is called (BTW, is that really right if Emacs is running as
a daemon?), and delete_frame tries to find another frame to select,
which in this case must be the initial frame, since there are no other
terminals left.  So I think the problem lies somewhere in delete_frame.

Alternatively, selected_frame might have become dead before delete_frame
was called on the frames in the second terminal, but I don't see how
that could have happened.

And the selected frame was something other than the initial frame when
redisplay was called, which is probably what's at fault here.

I think this isn't supposed to happen at all, especially since Ken is
running a daemon, so we shouldn't bubble wrap delete-process because of
this.

I will try to reproduce this again, hopefully I can get Emacs to crash
on my side as well.

Thanks.

I haven’t been, intentionally.  I think the GNOME environment is doing
it somewhere.  Emacs is launched as one of my startup applications;
emacsclient is run via an icon in the top bar on my screen, or a global
key binding, or, occasionally, from a Firefox plugin.

To clarify: I used to run Emacs as a daemon (which would’ve been
relevant if it meant there was another, invisible terminal frame), but
apparently I stopped a while ago.  That’s what I meant that my use of it
had “fallen by the wayside”.  (Perhaps I should’ve just not mentioned
it.)  So with both instances of the local display connection dead at the
same time, there are no working frames left.

In server-start, hooks are added to kill-emacs-hook and
delete-frame-functions, among others; tramp-dump-connection-properties
and org-babel-remove-temporary-directory are also on the list.  But
server-force-stop appears in the stack trace.  It calls server-start,
which calls delete-process, which calls redisplay_preserve_echo_area.

Which is why I said that perhaps we shouldn't call
redisplay_preserve_echo_area when we are shutting down Emacs due to a
fatal error.

Ah, thanks for clarifying.  I suppose there is no initial frame in that
case, so Eli's proposal about not calling redisplay_preserve_echo_area
seems reasonable to me.
