What context menu? Could you please describe how to obtain the buggy
menu, and how you are trying to click it, step-by-step?

Thanks.

I managed to reproduce a hang trying to click on the submenu item, but
then killed Emacs in an attempt to reproduce the problem again, and it
stopped happening.  Since that, I haven't been able to reproduce the
hang.

So it would be nice if you could try to find a way to reproduce this bug
from "emacs -Q", because I'm really lost.

Thanks in advance.

I can reliably reproduce the bug, but for me it's a sympton of broader
buggy behavior with menus in the Lucid build, which I've observed since
I started regularly building with the Lucid toolkit some months ago
(after not doing so for many years previously, so I don't know how old
this behavior is).

So while the items of a context menu (but not those of a submenu) can be
scrolled with the mouse, context menus are completely unresponsive to
keyboard events.  In contrast, with menus from the menu bar (whether
open via mouse click for with the F10 key binding), I can both navigate
and select (also in submenus) with the keyboard but other than opening
and closing, the menu bar menus are completely unresponsive to the
mouse.

Here's my current build info:

Could you please try to find out what this call to XtGrabPointer in
xlwmenu.c returns when you pop up a menu?

#ifdef emacs
  x_catch_errors (display);
#endif
  if (XtGrabPointer ((Widget)mw, False,
                     (PointerMotionMask
                      | PointerMotionHintMask
                      | ButtonReleaseMask
                      | ButtonPressMask),
                     GrabModeAsync, GrabModeAsync, None,
                     mw->menu.cursor_shape,
                     event->time) == Success) <-----------------
    {
      if (true

If you're going to be using a debugger, then please do the debugging
remotely from a different machine.  Otherwise, you will either lock up
your X server or waste a lot of time when the bug simply vanishes once
you try to debug it.

Either way, we have to get this fixed before Emacs 29 is released, so
please try to be fast here.  Thanks a lot.

I've done only elementary debugging with gdb and never from a different
machine, so I will need explicit instructions for how to set it up and
what to enter, and if it's not straightforward, I probably can't do it
soon.

But there may be a (for me) quicker way to investigate the issue: I'm in
the process of building a new system on this machine, which is an
updated version of my current system (on a different partition), and one
of the first programs I built after installing the basic system is
Emacs, first before installing X, then again with X but before
installing GTK.  On this system, the X build used the Lucid toolkit, and
with it I did not observe the menu problems I described.  Aside from
different versions of system libraries like glibc and build tools like
gcc, the two builds differ in their Emacs-specific configurations.  The
build with the menu problems used

 configure -C --with-x-toolkit=lucid --with-xinput2 CFLAGS='-Og -g3'

while the build on the newer system without the menu problems used

 configure -C --with-jpeg=ifavailable --with-gif=ifavailable --with-tiff=ifavailable

I'll try using the other configuration on the new system and see if that
makes a difference (though I probably won't get to that till this
evening.)

I ssh'd into my laptop from my phone to do the debugging.  More info on
what I did can be found in bug#57320, and specific instructions are in

IME, this bug goes away when you re-./configure Emacs so there's no
surprise this disappeared in your case.  It would be of help if I could
run the debug build all the time and wait for the menu bug to eventually
show up but alas it is far too slow for me to use it daily...

I don't think the specifics of the configuration options matter as long
as you run the Lucid build.

I don't even need to rerun configure.  I just added a debug fprintf to
pop_up_menu(), rebuilt Emacs, and the problem vanished.

I still have the binary that fails.  On a hunch, I added a breakpoint at
the start of pop_up_menu().  When the breakpoint triggered, I checked
the value of lucid__menu_grab_keyboard.  gdb says

(gdb) print lucid__menu_grab_keyboard
$2 = false

Yet *Help* says that the value of lucid--menu_grab_keyboard is t.

If I do 

  M-: (setq lucid--menu_grab_keyboard t)

and press F10, gdb says lucid__menu_grab_keyboard is still false.

I did a little more poking around with gdb and found that
lucid__menu_grab_keyboard moves around inside "globals".

Broken binary:

(gdb) print &globals.f_lucid__menu_grab_keyboard
$3 = (_Bool *) 0x555555d54a98 <globals+4152>

Working binary:

(gdb) print &globals.f_lucid__menu_grab_keyboard
$2 = (_Bool *) 0x555555d54ad0 <globals+4208>

This strikes me as more than a little odd.  Given that all I did was
add a couple fprintfs, I'd expect the layout of "globals" to stay the
same.

If I look at globals+4208 in the broken binary, it does have the value
true.

(gdb) print &globals.f_lucid__menu_grab_keyboard
$1 = (_Bool *) 0x555555d54a98 <globals+4152>
(gdb) print 4208-4152
$2 = 56
(gdb) print 0x555555d54a98 + 56
$3 = 93825000622800
(gdb) print /x 56
$4 = 0x38
(gdb) print *(_Bool *) 93825000622800
$5 = true

Not sure what to make of that.  I'm reluctant to conclude that there's a
toolchain problem.  But FWIW, I'm building on Debian 11 (amd64) and "gcc
--version" reports "gcc (Debian 10.2.1-6) 10.2.1 20210110".  emacs-29
branch (git hash a14821d615, plus some changes to MH-E).

Would you please send me the two different binaries?

I have a hunch.  If you touch globals.h in src, does it result in files
under the lwlib directory being rebuilt?

My guess is globals.h changed but lwlib was not incrementally rebuilt.
I guess this means lwlib/*.o has to be made to depend on
$(top_builddir)/globals.stamp or somesuch.  Thanks.

Hmm, the binary is 36MB (and the pdmp file is 12MB).  That's too big, I
think, to send by email.

I guess that's the problem then.  Emacs is using lwlib compiled with an
out of date libgnu.a.

So what I'd like to do is to remove the reference to
`lucid__menu_grab_keyboard' in the first place, and replace it with a
define.  Any objections?

Would this also involve removing f_lucid__menu_grab_keyboard from the
emacs_globals struct and removing the corresponding DEFVAR_BOOL in
keyboard.c?  pop_up_menu() is the only place lucid__menu_grab_keyboard
is used.

Ah, globals.h is automatically generated by make-docfile from the
various *.[cm] files during the build process.  This is why it is very
easy to end up with subtle differences in globals.h.  Especially in
lwlib, which has no business accessing Lisp anyway.

I don't think I understand the problem you are trying to fix, and the
messages recorded by debbugs don't help (maybe some were lost or sent
in private email?).  Can you explain the relevance of globals.h to the
subject of this bug report?

Dependencies for header files are supposed to be recorded
automatically in the deps subdirectory, as part of compilation of C
source files, so how come something is not recompiled when its
dependency header file changes?  And I have _never_ seen any problems
with how we generate globals.h or detect that its contents changed.

I thought only src had the AUTO_DEPENDS blurb.  Seems that I'm wrong.

Mike, what are the contents of lwlib/deps/xlwmenu.d on your system?

I've attached the version from my most recent backup.  Its mtime

what's currently in my build tree.

Here xlwmenu.o does depend on globals.h.  But I think lwlib is being
built before make-docfile is run, so we will need to make it depend on
make-docfile being run.

Does anyone have a better idea?

I think the dependency is the correct idea, yes.

Paul, is it true that lwlib/Makefile.in needs to define ALLOBJS for
the deps stuff to work correctly?

Although that should work, the attached proposed emacs-29 fix is a bit 
cleaner.

I've been bitten by the bug myself but never found the time to report or 
fix it until now. Although the bug is not a regression its symptoms are 
mysterious and the patch is simple and obvious. Your call as to which 
branch it should go into.

Subject: [PATCH] Fix dependency bug when building lwlib

* lwlib/Makefile.in (DEPFLAGS): Use OBJS to calculate dependency
file names, not ALLOBJS.  This fixes a typo introduced
in 2015-05-15 "Replace AC_SUBST_FILE in configure with include in
Makefiles" that caused lwlib/*.o to not be rebuilt sometimes
when that was needed.

Which files in lwlib should be rebuilt?  And what do you see in
lwlib/deps/ for those files?

Could it be that the root cause for this is that ALLOBJS is not
defined in lwlib/Makefile.in?  And also the fact that lwlib/deps.mk is
outdated?

We're particularly interested in seeing that lwlib/xlwmenu.o get rebuilt
when globals.h changes.  pop_up_menu() will not call XtGrabKeyboard() or
XtSetKeyboardFocus() if globals.f_lucid__menu_grab_keyboard is false.
And that seems to be what's behind all these intermittent problems with
Lucid popup menus.

lwlib/deps/xlwmenu.d looks okay to me, as it has:

xlwmenu.o: xlwmenu.c ../src/config.h ../src/conf_post.h ../src/lisp.h \
 ../lib/alloca.h ../lib/string.h ../lib/inttypes.h ../lib/attribute.h \

I think you've identified the problem.  I tried hacking lwlib/Makefile
as follows:

Now, when I touch src/globals.h and run "make", xlwmenu.o does get
rebuilt.

The only difference I can think of in that case is which Athena widgets
variant is used, since XInput 2 is now enabled by default.  What do the
scroll bars look like in either of those builds?

I can't check right now because I'm on the older system and need to do
work there.  But it occurred to it that I can try compiling the Lucid
build here as I did on the new system, i.e. only --with-x-toolkit=lucid,
and it still has the menu problems, so the build configuration does not
account for the difference.

But I also have a number of emacs executables of the Lucid build and I
found that menu problems do not occur in my build from commit
177811ac0c0e5e41d4f661e8e5553e46f0019b9a (Sept 2) but do occur in my
next build, from commit c6fc00f5d75a28fd4e99050ccc1af9ad82f66b2b (Sept
15, more recently than I remembered).  In the build from Sept 2 the
context menu seems to hang for several seconds, during which there is no
response, but then it seems to work ok, as do the menu bar menus, while
the build from Sept 15 has the problems I still see now.  When I have
more time I can try bisecting.
