bug#56869: 29.0.50; segfault, "assertion 'GDK_IS_DEVICE (device)' failed"

[Joe Corneli via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hi,

I’m not sure what has triggered the segfault, but it happens fairly
predictably with the latest version of Emacs.  I didn’t see anything
like this when I was using the previous stable version, however.

If I can provide further useful information please let me know.  Note
that xbacktrace doesn’t print anything.  I’m running Emacs under the
regolith WM (2.123-1focal), in case that’s relevant.

I suspect this is either a bug in GDK, or we're not passing through an
XI device hierarchy-related event somewhere, which has happened before.

Could you please install debuginfo for GDK and see where in GDK the
crash happens?

Thanks in advance.

I’ve tried running things like this:

joe@Proteus:~/emacs$ export GDK_DEBUG=events
joe@Proteus:~/emacs$ export GTK_DEBUG=misc
joe@Proteus:~/emacs$ emacs &

(I tried with the "all" option, but it slowed Emacs down too much.)

If I should do something else to get better debugging info out please
advise, otherwise I shall carry on like this, and may see the crash
again before long, with some further information.

Now got these messages out, leading up to and just before the crash.
I’m not sure what can be learned from this, so I pasted a lot of mostly
repetitive context.

I'm sorry, but those trace messages don't really help.  Please install
the debugging symbols for GDK (usually available in a separate
"debuginfo" package repository on GNU/Linux systems), so we can find out
exactly what event is causing the crash.

Thanks.

Got it now, I didn’t immediately understand.  I followed the
instructions to install debugging symbols for Ubuntu, here,
https://wiki.ubuntu.com/Debug%20Symbol%20Packages
found via
https://drgn.readthedocs.io/en/latest/getting_debugging_symbols.html

and then installed these:

sudo apt-get install pcb-rnd-hid-gtk2-gdk-dbgsym
sudo apt-get install libgtkgl2.0-1-dbgsym

I hope that’s the correct protocol; haven’t re-encountered the crash
yet.  More soon, if I do!

Now it’s produced the following, alongside the crash.  I’m happy to
adapt the instrumentation further if this is not yet sufficiently
useful!

Could you please type "coredumpctl debug emacs", and then in the
debugger prompt, type "bt", and send the complete backtrace?

In the meantime, I made an attempt to fix this on master based on some
serious guesswork.

Thanks.

My core file was produced via running Emacs under GDB and running
generate-core-file, hopefully the result is the same!  The backtrace is
below.

The backtrace says:

 . the main loop called some command
 . that command signaled an error
 . the error caused the Lisp debugger to be called
 . the debugger was invoked and entered recursive-edit
 . while waiting for user input, a timer fired
 . the timer function called write-region
 . write-region called lock-file
 . lock-file called a Lisp function, probably to report some conflict
   with another process(??) locking the file
 . Emacs prompted the user, probably about the lock
 . while waiting for user response, Emacs checked timers, and as
   result called process_pending_signals
 . one of the pending signals was SIGIO, so Emacs called read-socket,
   which segfaulted inside GTK

Does the above sound reasonable for your Emacs sessions?

Thanks.  Unfortunately, you don't seem to have installed the right
debuginfo package for libgdk-3, so this information still doesn't help.

Could you try to install the `pk-debuginfo-install' utility (normally
provided by a `packagekit-tools' package) and run the following command
instead?

  pk-debuginfo-install <name-of-libgtk-3-package>

It seems plausible, GTK aborted because it received an X event that it
couldn't find a corresponding device for.  So to really figure out what
event is causing the problem, you have to look inside GTK, because on
GTK builds it's reading events and not XTread_socket (which just calls
gtk_main_iteration.)

Hm, I think I missed the obvious ones.  Have added:

sudo apt-get install libgtk-3-0-dbgsym libgtk-3-bin-dbgsym

If it crashes again, I’ll give more info.

Thanks, that’s certainly a reasonable chain of events, e.g. given that I
have mu4e running (which likes to use locks) and there might have been a
conflict between two different running instances.  Not sure about the
last step involving GTK.  In my workflow I think the crash occurred only
when I was switching between windows in my WM.

OK, I think I’m now able to provide the debugging info you were asking
for!  As far as I could tell the specific interaction that triggered
this was switching between windows.

Thanks.  Unfortunately, the line number doesn't make much sense, so
could you also type "l" at the debugger prompt and show the output?

Sigh, I guess you need the source packages as well.  Not sure what that
would be on Debian.

In light of the previous, I think this is what’s needed.  Details will
be forthcoming with the next crash!

OK, here’s the next round of backtrace.  Now it includes some Lisp
details, implicating feebleline (https://melpa.org/#/feebleline) as the
source of the problems.

Async input can be read almost anywhere, and that includes from Lisp.
So feebleline is most likely not the problem here.

As I said, the line number is unfortunately not very informative, so
please type "l" to show a listing of the GDK code at that particular
line.

Thanks.

For now, I’ve turned off the feature that seemed most suspicious...
https://github.com/tautologyclub/feebleline/issues/66

If it turns out that I don’t have any crashes then great!  Otherwise,
more reports will surely follow.

Sure, though I forgot to save the core file last time, so I can’t press
"l" in gdb, but here are indicative code snippets from the files named
in the previous backtrace.  The mentioned lines are marked below:

...  M-x occur RET /\*[0-9]+\*/ RET

Thank you!

Thanks.  That's pretty odd, I guess gdk_device_get_seat is what's
failing here, followed by the reference to source_device->last_tool
causing a segfault.

When you next encounter this crash, please show the value of
"xev->sourceid" (p xev->sourceid in gdb) and the shell command "xinput
list-devices" immediately after it happens.

OK, here’s the info:

... and another possible clue, which is that I’m running Touchpad

and I have it set up to disable the trackpad _while typing_.  Perhaps
the way it enables and disables the trackpad is currently interacting
with Emacs in a glitchy way.

Right, I think I know what this is now.  GTK fails to read information
about the trackpad due to it being disabled between the
XI_HierarchyChange event being sent and and it being handled.  GTK then
segfaults trying to access a field in a device it doesn't know about.

This only shows up in Emacs, because most other GTK programs do not make
people rapidly alternate between trackpad and keyboard use.

I suggest using a build of Emacs without GTK.  If you have to use GTK,
turn off '--with-xinput2', but as a result several features will no
longer work.

Thanks.

BTW, the quality of the GDK X11 backend has lately dropped to a very low
level.  I'm going to push for the Emacs build to default to the Motif or
no-toolkit build instead.

The no-toolkit alternative will be a hard sell, IMO.

Why not Lucid?

Hi Po, Eli,

Thanks for the suggestions, and for helping me to understand the
debugging symbols etc.

I’ve updated my build for Lucid.  Looking around I think --with-xft is
also needed in that case.

If you want color Emoji support, you should be using Cairo instead of
Xft.  Both are enabled by default, with Cairo taking precedence over
Xft, so --with-xft is redundant on a system with Cairo installed.

Indeed.  In general, we advise against using Xft, as it is
unmaintained and has known issues with displaying some characters.

Thanks, so it seems like the solution is to use a build without GTK or
'--with-xinput2'.  I'm therefore closing this bug report.
