bug#54889: 29.0.50; shift keys can't function when using setxkbmap with custom_symbol in gnome

[-- Attachment #1: Type: text/plain, Size: 4928 bytes --]

Hi,
first, thanks for solved ibus input problem last time .

now, I am struggling to config hot key in normal pc104 layout keyboard for
too few key can be set.
and tried to use xkb to set extra key level, and work fine in privious
emacs v27, 28.

because i can't made Caps_Lock to remap to control key working with
'setxkbmap' ,
so first, using cmd to change RWIN and MENU key in gnome:
  gsettings set org.gnome.desktop.input-sources sources "[('xkb', 'us'),
('ibus', 'rime')]"
  gsettings set org.gnome.desktop.input-sources xkb-options
"['caps:ctrl_modifier', 'lv3:rwin_switch', 'compose:menu-altgr']"

second, using setxkbmap to chang symbols:
 setxkbmap -model pc104 -layout us -keycodes mykeycode -types mytype
-compat mycompat -symbols mysymbol
(all files in each dirs under /usr/share/X11/xkb)

all keys work normally,
my extra key level and group are working fine,
but Shift_L, Shift_R are no function when i using  emacs -q in v29 .
i saw `H-_   is indefined` in minibuffer but no any letter inserted when i
tried to input any capital letter .

finally, i found it can input capital letter, if i removed modifier_map of
shift keys:
in xkb_symbols file:
    // modifier_map Shift { <LFSH> };
    // modifier_map Shift { <RTSH> };
   //  modifier_map Shift { Shift_L, Shift_R };

my xkb files in here:

https://drive.google.com/file/d/19_tcP8VSeUYgG9f4zkGEbavbaBOwOLso/view?usp=sharing

and using cmd:
setxkbmap -model pc104 -layout us -symbols mysymbol
or
xkbcomp .config/xkb/myxkb_keymap.xkb $DISPLAY

now, emacs v29 shift key plus any letter can be inputed capital letter.

because the same xkb keymap is woring normally in emacs 27, 28,
so i am wonder if there is any difference in mechanisms of keymap in emacs
v29?

A great deal has changed under the hood.

Would you please show the output of `xmodmap' with the shift key mapping
rules that you removed installed?

Thanks in advance.

I asked for the the output of `xmodmap' (without any arguments,
including "-pk") when your system is configured so that typing Shift+N,
for example, results in "H-_".

Did you try building `--with-xinput2'?  And do you have any funny
options such as `x-gtk-use-native-input' enabled?

What happens if you run Emacs like this?

  emacs -q -xrm 'Emacs.useXIM: false'

Thanks in advance.

You forgot to enter "run" and then press Shift-A here once the input
focus shifts to the Emacs window.  I'm sorry for not mentioning that
earlier.  Thanks.

It seems that your copy of Emacs is slightly out of date, please update
and try again.  Thanks in advance!

But this does say that hyper_mask is set to what is normally ShiftMask
on X.  What happens if you comment out this bit of code in the function
`x_find_modifier_meanings'?

	  else if (dpyinfo->xkb_desc->names->vmods[i] == dpyinfo->Xatom_Hyper)
	    dpyinfo->hyper_mod_mask |= vmodmask;

Thanks.

i tried the version of emacs today,
it still do not give me chance to input ,
gui emacs freeze when gdb showed the prompt again,
i tried to press key before it freeze,
the result is showed below:

i also tried to comment out that you say this :
         else if (dpyinfo->xkb_desc->names->vmods[i] ==
dpyinfo->Xatom_Hyper)
            dpyinfo->hyper_mod_mask |= vmodmask;

after rebuild,
the capital letter can normally insert with shift now.
hope it useful.

Thanks

So something in your virtual modifier map is binding Shift to Hyper.
That's a bug in your setup, not in Emacs.

Thanks.

I serched my map and found no config part  had Hyper for virtualModifier ,
but i found Hyper_R config in symbols  <RTSH>  in group 2,
after changed to Shift_R,
i can inser capital letter in emacs 29.
old:   key <RTSH> {  [         Shift_R, Shift_R, U2E9D] ,[ Hyper_R ] };
new:   key <RTSH> {  [         Shift_R, Shift_R, U2E9D] ,[ Shift_R ] };

I don't know why cause that,
since that is not belong parts of emacs,
I feel so sorry any where for this report let you be troubled.

Anyway, thanks you for your help.

No problems here, glad I could be of assistance.  I'm closing this bug.
