bug#70073: 29.3; Emacs-PGTK crashes upon marking some text inside emacs and then middle clicking outside of Emacs

[Abraham S.A.H. via Bug reports for GNU Emacs, the Swiss army knife of text editors]

## System Information:

* Kernel: 6.8.2-2
* DE: Gnome 46.0
* WM: Mutter (Wayland)
* gnome-shell: 46.0
* wayland: 1.22.0
* mutter: 46.0
* wl-clipboard: 2.2.1
* weston: 13.0.0
* sway: 1.9-e93da93
* emacs package: emacs-wayland 29.3-1.1 (archlinux)

## Steps to reproduce the issue under Gnome:

1. Invoke `emacs -Q` in any terminal emulator to start Emacs along with
   its GUI frame.
2. Mark/highlight some area of text with your mouse pointer. OR use
   C-Space and keyboard movement shortcuts to do the same.
3. Open any other application. (gnome-text-editor, for example)
4. Use your middle mouse button in an editable text area of the second
   application's frame.
5. Emacs crashes.

NOTE1: Emacs doesn't crash if you just middle click in any 
       *non-textual/non-editable* area, outside Emacs.
NOTE2: Middle clicking *inside* any of Emacs' own buffers DOES work
       properly without any crash or noticeable problem.
NOTE3: The problem is reproducible both when marking with mouse cursor
       or when marking with keyboard shortcuts.
NOTE4: Using another shortcut that pastes the Primary selection of the
       wayland, instead of mouse's middle click, also reproduces the 
       same issue. E.g. S-Insert of WezTerm.
NOTE5: Marking a text outside of Emacs and middle clicking inside
       Emacs works flawlessly.

## State of the issue under Sway:

The issue is completely reproducable under sway with the same steps as
above, with the same symptoms and the same segmentation fault error.

## State of the issue under Weston:

The issue is not reproducable under Weston but the functionality is
also lost.  Weston doesn't support primary selection.

## Tried Workarounds:

### Workaround number 1:
Disable the primary selection.  In gnome you can disable 
primary selection.  Brings users to the same state of under 
Weston.  Emacs will not crash, Primary selection works inside 
Emacs, but not outside of Emacs.

Emacs still crashes if user uses the middle click inside applications
that try to pull primary selection with middle click.

### Workaround number 2:
Set variable `select-active-regions` to `nil`.	Disables the
functionality and of course removes the issue.

Is this different from bug#70072 that you submitted a few minutes ago,
or is this the same problem?  It sounds almost the same problem, just
triggered in 2 different ways.

Thank you for your report, but these backtraces can only be
interpreted on your system.  So either convert them to human-readable
lists of file names, line numbers, and function names as described in
the node "Crashing" of the Emacs user manual, or run Emacs from GDB,
and when Emacs crashes, type "bt" at the GDB prompt and post the
backtrace produced by GDB.

The least I could do. 

That's the end of the day in my time — Tehran's time. I will do it again
with GDB as you instructed, tomorrow.

It's saying right.  When I ran the bug report command, Emacs was invoked
with both `-Q` and `--debug-init` flags.  But the issue and backtrace is the
same, nonetheless.

Exactly, it seems to be the same issue, triggered in 2 different ways. 
Even the crash backtrace is the same.

By the way!  I have tried `emacs-pgtk-native-comp-git` of AUR, which is
Emacs dev master branch (30.0.50.171462) with PGTK and I could NOT
reproduce the bug.  This is the only available package of Emacs dev branch
with PGTK enabled, in Arch Linux.

I'm therefore merging the two bugs.

bug#70073: 29.3; Emacs-PGTK crashes upon marking some text inside emacs and then middle clicking outside of Emacs

[Abraham S.A.H. via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hello. I ran GDB with `gdb emacs`.

It downloaded some debuginfo stuff that I don't know what are they.

And then I ran `run -Q` 

It's the result on the terminal:

It seems like that `emacs-wayland` package does not contain debug symbols.  I have to probably consult with Arch Wiki or ask for guidance in archlinux mailing lists to find out if there is a version with debugging symbols enabled to download.   Or just rebuild the package with debugging symbols enabled.

Yes, please.

bug#70073: 29.3; Emacs-PGTK crashes upon marking some text inside emacs and then middle clicking outside of Emacs

[Abraham S.A.H. via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Okay, the Arch debug repository (extra-debug), does not contain a debug package for `emacs-wayland`.

Interestingly, `emacs-wayland` package is built with a single PKGBUILD file[1] containing instructions to build all other Emacs packages in Arch official repository.  So to reproduce `emacs-wayland` the same way it's built for Arch's repository, I have to build three other Emacs packages alongside `emacs-wayland`.  Those other three are `emacs`, `emacs-nox` and `emcas-nativecomp`. 

The other option for me to reproduce `emacs-wayland` package, is to review that file and write another one which just build that single package.   

I'll do the first later and then report.

Thank you.

[Abraham S.A.H. via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Sorry for delay.

I got the opportunity to build Arch's `emacs-wayland` package myself, from the same PKGBUILD file used to build it in Arch's official repositories, including debug and without stripping anything. The result was about 30mg increase in size of the final built Emacs.  And the issue still persist.

Now that I got time to build it and can more responsively reply for anything needed about this issue.

BY THE WAY, checking arch-devel and arch-general mailing lists and also "issues" page of the emacs pacakge, it seems like no one else have this issue… kinda only happening to me!

During the time, I gave GTK+ and Lucid toolkits a try, and now I decided on staying with the lucid toolkit. Even switched my whole desktop, from Pure Wayland of Gnome, to Pure X11 of Xfce4.  

I think, I stay with it until using X is not practically possible.  Or when PGTK is recommended by you (Emacs-devs).

bug#70073: 29.3; Emacs-PGTK crashes upon marking some text inside emacs and then middle clicking outside of Emacs

> I got the opportunity to build Arch's `emacs-wayland` package myself, from the same PKGBUILD file used to build it in Arch's official repositories, including debug and without stripping anything. The result was about 30mg increase in size of the final built Emacs.  And the issue still persist.

The increase of the executable size is because it includes debug info.

At this point, please type at the GDB prompt:

  thread apply all bt

and post the backtrace produced by GDB.  That's the information we
need to try to figure out what causes these crashes.

Thanks.

Po Lu, any idea why pgtk_handle_selection_request segfaults at that
point?  Is dpyinfo or dpyinfo->terminal a NULL or invalid pointer or
something?

That should not be possible.

Thanks in advance.

Thanks.  Would you try this instead:

  (gdb) p *$1->dpyinfo
  (gdb) p *$1->requestor

?

bug#70073: 29.3; Emacs-PGTK crashes upon marking some text inside emacs and then middle clicking outside of Emacs

[Abraham S.A.H. via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hello;

I have wiped out everything of my system and installed just Xfce4 
and sway (for testing Emacs PGTK).

By wiping out, I mean formatting my entire disk, then repartitioning and
reinstallation of my new desktops and neccessary applications.

The problem still persists. I include the result of 
report-emacs-bug with this new system with this email.

One reason for me replying late is that I have to uninstall emacs-lucid 
and reinstall emacs-wayland and switch to a wayland desktop, each time 
that I want to test it. However, this time I was also busy with some other
works.

Po Lu, any suggestions for how to move forward with this issue?

I wasn't aware that Xfce4 supported Wayland, but apparently it does now.
I will try to reproduce this with the Fedora-built Emacs 29 the OP
appears to have installed.

Xfce4 doesn't support Wayland. Even Their roadmap for supporting Wayland is exprimental.  

I have exprimented the issue on Gnome, first.  Then reproduced it on Weston and Sway.  And reported.

Then, I have reinstalled a new system only with Xfce4 and also Sway.  I test Emacs PGTK build on Swaya, at the moment.  But, use Emacs Athena on Xfce4.  Basically learning it in my spare time.  I found Emacs about a month ago.

All this is on Arch not Fedora.--

Right.  I couldn't reproduce this on Fedora, neither with our Emacs 29.3
tarball nor with their downstream release.  Does your distributor apply
patches to their Emacs binaries or thereabouts?
