From: Visuwesh <visuweshm <at> gmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 31.0.50; X protocol error: BadGC (invalid GC parameter) on protocol request 60 Date: Tue, 11 Mar 2025 20:58:53 +0530
While trying to reproduce bug#73456, I ended up with a different error.
When using Emacs as usual, all frames except one were killed. However,
I still did not get the GDB prompt so I did
% kill -USR2 EMACS-PID
to no avail. Later, reading etc/DEBUG asked me to do
% kill -TSTP EMACS-PID
which ended up with
Thread 1 "emacs" received signal SIGTSTP, Stopped (user).

futex_wait (futex_word=0x7ffff701f8c0, expected=2, private=0) at ../sysdeps/nptl/futex-internal.h:146
warning: 146 ../sysdeps/nptl/futex-internal.h: No such file or directory
After producing the backtrace (see below), I could not see the
*Messages* buffer after `c', so I followed etc/DEBUG further and loaded
etc/emacs-buffer.gdb, and got a dump of the *Messages* buffer. This has
Auto-saving...done
X protocol error: BadGC (invalid GC parameter) on protocol request 60

This is a bug! Please report this to bug-gnu-emacs <at> gnu.org!
It says to report it, so here I am. I have the core file for this
process, and still haven't killed it. I started Emacs under gdb as:
(gdb) run --fg-daemon=vz -xrm "emacs.synchronous: true"
The build information in the bug report, and that of the dead(?) Emacs
should be the same. I built Emacs with CFLAGS=-g3 as per Eli's advice
in bug#73456. This new error was obtained _after_ the error in
bug#73456 was shown. Gdb did not break then however, so I couldn't get
a backtrace.
I hope the backtrace this time is somewhat helpful.

I expect that the X error handler longjmp'ed from a Cairo routine called with one of its locks held, producing this deadlock during a subsequent invocation. You must also break on x_error_quitter. That will reveal the true source of the X error.

That will reveal the true > source of the X error. [ I neglected to do this, will do it once/if I restart the server process again. ] I can't get a response from Emacs. If I do `c' a couple of times after `kill -TSTP EMACS-PID', the gdb prompt eventually goes away, but Emacs is still completely frozen. I am assuming the process is as good as dead then?

Unfortunately, no. I made the mistake of not reading etc/DEBUG carefully before starting Emacs from gdb.

Hmm, from what I understand, src/.gdbinit already sets a break point for
this function. I think the command line flag -xrm "emacs.synchronous:
true" wasn't respected by the daemon which is why I couldn't get a
proper backtrace out of the previous process? I now did
M-: (x-synchronize t)
in a frame, and it is noticeably slower to type. However, it seems like
I need to do this for every frame I open.
How can I check if the xrm flag is respected? Doing
M-: (x-get-resource "synchronous" "Synchronous")
returns nil.

Judging by the backtrace and the deadlock in acquiring an internal Cairo lock, some error was detected and prompted Emacs or another error handler to longjmp with that lock held. The state of XSynchronize is not really material now--if a breakpoint was indeed placed on x_error_quitter, perhaps you could attempt to break on x_io_error_quitter or _XError this time.
