Hello,

    I maintain the the GNU emacs delivered with the
Solaris OS:

     https://github.com/oracle/solaris-userland/tree/master/components/emacs

We're still at version 28.2. It's getting long in the
tooth, so I recently tried to move to 29.2. There were no
issues on x86, but on sparc, I see display problems with
both the gtk (emacs-gtk) and lucid (emacs-x) versions that
prevent it from running.

I double checked version 28.2, which we are currently
delivering, and it has no problem. Then, I built 29.1,
and it shows the same issues as 29.2. It seems that
something was introduced early in the 29 series.

With the GTK version, I see 3 different failures on repeated
attempts:

1)

     % emacs-gtk
     Connection lost to X server 'localhost:10.0'
     When compiled with GTK, Emacs cannot recover from X disconnects.
     This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221
     For details, see etc/PROBLEMS.

     Note that I don't believe that X disconnects are involved.
     This happened immediately at startup.

     Sometimes, this clobbers the state of my video card, leaving
     me with a black screen with a large white square in the upper
     left corner. When this happens, I log in remotely, and using
     ps, it appears that my desktop is still running, so the X server
     is unaware that the video hardware has been whacked. I can only
     assume that a bad request is not being caught by the X11 server,
     which is likely a second bug.

With the Lucid version, I normally get this result, after
a long pause:

     % emacs-x

     Connection lost to X server 'localhost:10.0'

The fact that both the plain X11, and GTK, versions, have
problems seems to point at some generic non-toolkit specific
X code. Perhaps this is an endian issue (x86 works fine), or
maybe there's some uninitialized data involved.

I asked Rainer Orth, who I work with on Solaris gcc issues, and
who I know is also an emacs user, and he was able to confirm the
same issues, using a different X server:

     >> side, I primarily use emacs to run gdb, which I haven't done in a
     >> while.  I can give it a whirl, though.

He also reports the same issue with Debian/sparc64, which
we think means that it seems not to be an OS-specific issue:

I'd appreciate it if someone who knows this code could have
a look. I'm happy to try patches or experiments to help narrow
the issue down further.

Thanks.

Emacs works fine on sparc64-sun-solaris2.10, but the difference is that
the X libraries and servers installed there are ancient and predate the
introduction of generic events or XInput 2.  The backtrace Rainer
produced demonstrates that the client-side abort is consequent on the X
server crashing as it attempts to respond to an XIGetSelectedEvents
request, which is _always_ a bug in the X server, whatever the
circumstances, and so I suggest redirecting your attention to X.Org, and
building `--without-xinput2' in the meantime.

    Thank you, this is very helpful. I guess I'm not too surprised
that it works on Solaris 10. Your support of a 20 year old OS is
admirable.

I tried --without-xinput2 with the GTK version, and it does
indeed skirt the problem. I can now reliably run it without
crashing.

Since this all worked with 28.2, I guess that Emacs
started using XInput 2 features in the 29.1 branch?

Unfortunately, with the Lucid version, while --without-xinput2
seems to get past the failure I reported, there's now a different
failure:

     % src/emacs
     X protocol error: BadDrawable (invalid Pixmap or Window parameter) on protocol request 134
     Serial no: 1318

Please run Emacs under gdb (or some other suitable debugger, e.g. dbx)
with the command-line options:

  -q -xrm 'Emacs.synchronous: True'

exactly as written above, break on xterm.c:x_error_quitter, and reply
with the backtrace generated after this breakpoint is hit.

I'm afraid not. I get the same result as before:

     % src/emacs

Several additional lines should have been printed after the failing
request's serial number.  Would you please post the error message in
whole?

That really is all the output.

I'm running it as 'src/emacs', out of the workspace
that I built with the patch applied, as well as configured
with --without-xinput2. Did I miss a step, or should I be
running it differently?

Nevermind, the code to print this information wasn't installed in the
Emacs 29 branch, being written awfully close to the time of the release.

Please apply this patch and respond with the error message the patched
Emacs generates:

    This output is from emacs-x with both patches
applied:

     % src/emacs
     X protocol error: BadDrawable (invalid Pixmap or Window parameter) on protocol request 134
     Serial no: 1318
     Failing resource ID (if any): 0x5901a002
     Minor code: 14
     This is a bug!  Please report this to bug-gnu-emacs@gnu.org!

Note that I had to move the comma at the end of

     > +	   "Minor code: %d\n",

to the end of the following line. I only mention it in case
it's a sign that something else was intended.

Standing by for the next iteration. Thank you!

    I'm afraid that it still fails with the same error:

     % src/emacs
     X protocol error: BadDrawable (invalid Pixmap or Window parameter) on protocol request 134
     Serial no: 1318
     Failing resource ID (if any): 0x43020000
     Minor code: 14
     This is a bug!  Please report this to bug-gnu-emacs@gnu.org!

-----

The following isn't a fix, but I've come up with
a workaround.

I was looking at the code for x_sync_init_fences() that
we've been doing these experiments on. I noticed that
that this code is not always used:

  /* Sync fences aren't supported by the X server.  */
   if (dpyinfo->xsync_major < 3
       || (dpyinfo->xsync_major == 3
           && dpyinfo->xsync_minor < 1))
     return;

Hence, the sync fence support is optional, and emacs is
willing to run without it.

It's also only compiled in when built on systems that know
the extension, guarded by a '#ifdef HAVE_XSYNCTRIGGERFENCE'.

And lastly, it's only called for non-GTK X11, which essentially
means, only for Lucid:

     xfns.c

     #if defined HAVE_XSYNCTRIGGERFENCE && !defined USE_GTK \
       && defined HAVE_CLOCK_GETTIME
           x_sync_init_fences (f);
     #endif

So this works on Solaris 10 sparc, because those
old X11 bits lack the sync fence extension. And it
"works" on current Solaris GTK, because it's not used.

Hence, the workaround, which is to put this at the top
of x_sync_init_fences():

   /* This feature does not work properly on sparc */
   #ifdef __sparc
     return;
   #endif

With that in place, Lucid emacs starts, and runs normally.
This is clearly not a proper fix, but it is an effective
workaround, and presumably, no worse that using emacs 28.2,
which completely lacks sync fence support.

I wonder if we might be looking at a problem with the
sync fence extension on sparc?

Although I now have usable way around the issue, I'm willing
to continue with any experiments you want to try. Let me
know...

Thanks!

- Ali

That's more than likely, yes, though one wonders why Emacs is the first
program to call attention to this problem.  The only role of the
drawable parameter to SyncCreateFence is as a reference to its screen,
which is completely defeated if not even the screen's root window is
deemed valid.

I don't think such a drastic measure is necessary under the
circumstances.  We should (please test) put this down as a bug in the
X.Org server and install an error trap around SyncCreateFence requests,
thus:

Po Lu, please document in PROBLEMS that XInput2 has bugs on Solaris
(probably only reecent versions?)

I actually plan to install a workaround for the non-toolkit builds once
we arrive at a solution for the other bug under discussion.  Thanks.

It's a good question, and I don't know the answer.
However, it's worth noting that it's been 20 years
since sparc machines came in desktop form, with a
display, so the number of people running X11 clients
on them likely isn't large. I myself usually use the
plain tty version in those contexts.

The x_ignore_errors_for_next_request() in 29.2 only
takes the dpyinfo argument. I dropped the second argument
from this patch, applied it, and it works. We could go with this,
rather than my

     #ifdef __sparc
	return
     #endif

construct. It probably amounts to the same thing,
except that should a fixed XSyncCreateFence() come
along, this version would start using it.

Thanks!

    We don't see this issue on Solaris/X86, and we did see
it on Debian/sparc. We won't really know until the issue is
root caused, but I'd say "on sparc" is probably more accurate
than "on Solaris".

Regarding recent versions, it's not known at this time.
We only know that it works on Solaris 10, a 20 year old
system that lacks XInput2, and does not work on the latest
Solaris. Although it's possible that this worked on slightly
older versions of Solaris/sparc, I haven't tested. My unverified
hunch is that it's more likely that XInput2 never worked on
sparc, and no one noticed until emacs 29 came along. If so,
then this bug could go back a decade or so (google tells me
XInput2 was proposed in 2012).

Whatever the conditions for the X server crash, please report it (or ask
Rainier to do so) to the X.Org developers.  Between the recent deletion
of support for byte-swapping and its developers transition to only
assembling Xwayland releases, there is very little love remaining in
that organization for the rank-and-file of X users, and every reminder
of our existence counts towards restoring some of that lost dedication.
If you catch my drift.

Thanks.

Ali asked me to look into this bug as one of the X11 maintainers for
Solaris, but I also am one of the upstream maintainers for X.Org.

There's still some of us working to maintain X11 for X11 users (mostly
because Wayland isn't an option for our kernel).  Also note that byte
swapping was *not* deleted, just disabled by default and can be easily
re-enabled.   Which is important here, because the bugs Ali & Rainer
found are not SPARC-specific, but caused by them running emacs on a
SPARC and displaying it onto an x86 desktop, thus invoking the byte
swapping code where both the Xsync & Xinput2 bugs lie.

I've merged a fix upstream for the Xsync bug already, as it was quite
simple: https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/1437/

The Xinput2 one is a little more involved and I'm working on getting it
fixed upstream now.

    It also means that the extra error handling
you put together as a workaround can probably
be omitted. Had that workaround been in place
earlier, we would never have found and gotten
these issues fixed.

Thanks again for all your time in debugging this.

Thanks, but our policy is to support all X servers users might plausibly
encounter, so the workaround must remain, all the more so with such a
widely-distributed X server.
