bug#49955: 28.0.50; Emacs got quasi freeze

[Masaru Nomiya]

Hello.

With this pacth;

commit 483c5e953c12a95382bef4a3b6769a680c32fe86
Author: Martin Rudalics <rudalics@gmx.at>
Date:   Wed May 5 10:26:32 2021 +0200

    Fix two GTK3 event handling issues
    
    * src/xterm.c (handle_one_xevent): For GTK3 PropertyNotify and
    MapNotify events explicitly request the stored frame sizes when
    the frame changes from iconified to a non-hidden state
    (Bug#24526).  For Expose events do not change the frame's
    visibility or iconified state.  For FocusIn events on GTK3 do
    not apply the fix for Bug#42655.  The latter two changes are to
    avoid that plain invisible frames get reported as iconified.

Emacs has often got a quasi freeze, not perfect freeze but doesn't
accept any openraion except quitting operation.

Sorry for the report only.

Regards.

Could you try (setq debug-on-quit t) and post the resulting backtrace
you get when you `C-g' when it hangs like this?

I did it many times, but can't get the backtrace at all.

Darn.  Do you have a recipe to reproduce the problem, starting from
"emacs -Q"?

This issue was solved by;

Tweak x_connection_closed when I/O error
* src/xterm.c (x_connection_closed): Don’t dereference dpyinfo
in the unlikely case where it is null and ioerror is true.
This pacifies gcc 11.2.1 -Wanalyzer-null-dereference.
 master

Thanks a lot!

I suppose this means that Bug#49959 is fixed too.  Do you have any
explanation why and how these bugs are related to Eggert's fix?

Thanks, martin
