Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect, P2)

Description

[Andrei Petcu]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

GDK_BACKEND=wayland /path/to/firefox/nightly
add or remove an external monitor


Actual results:

I get this crash https://crash-stats.mozilla.org/report/index/fbf0bd31-a5d8-4389-bacf-cdea00190101


Expected results:

no crash

Comment 1

[Andrei Petcu]

I use Fedora 29 with Gnome shell

Comment 2

[Andrei Petcu]

Just to be clear: by default this crash does not happen. Wayland is not on by default in v66. I had to opt into the new wayland backend to reproduce the issue.

Comment 3

[Val Packett]

I can reproduce the crash on Weston. Different (even less helpful?) backtrace though:

But it does not crash when a debugger (lldb) is attached (!), just prints these:

…

###!!! [Parent][MessageChannel] Error: (msgtype=0x2000C,name=PAPZ::Msg_Destroy) Channel error: cannot send/recv

Comment 4

[Andrei Petcu]

Does it help if I reproduce the crash with ASAN? I can try.

Comment 5

[Val Packett]

hm, with a new experimental compositor launching setup (consolekit2 running weston) I'm actually seeing the same "channel error" without any monitor hotplugging, just spontaneously all the time, interesting

Comment 6

[Val Packett]

Sorry, disregard comment #5, that was an unrelated issue, XDG_RUNTIME_DIR ended up on ZFS which doesn't support posix_fallocate.

With MOZ_NO_REMOTE=1 I got the same stack trace as OP. Though only once. I tried to replicate with debug versions of GTK and libwayland installed, but the crash didn't happen again (even after reinstalling the optimized/stripped versions of these libraries again). I'll try restarting the compositor (or the whole system).

Comment 7

[Val Packett]

err, that actually happened in multi-process mode, MOZ_NO_REMOTE doesn't seem to actually turn it off

Comment 8

[Gabriele Svelto [:gsvelto]]

Adding more crash signatures for crashes with the same stack traces. Note that there's more crashes with libwayland-client.so.0.3 in their signature but they're unrelated, the stacks are completely different.

Comment 9

[Dan Callahan [:callahad]]

I'm also seeing this; adding my crash signature to the mix. :-)

Comment 10

[Martin Stránský [:stransky] (ni? me)]

Half of the crashes are from _fini which looks like they happens on browser exit.

Comment 12

[Martin Stránský [:stransky] (ni? me)]

Can you please attach content of about:support? Thanks.

Comment 14

[Andrei Petcu]

Hmm. It does not reproduce on my computer anymore. How about you, Dan, Gabriele and Greg?

Comment 15

[Gabriele Svelto [:gsvelto]]

I use Xfce so no Wayland for me (yet).

Comment 16

[Andrei Petcu]

might be a different bug for you.

Comment 17

[Martin Stránský [:stransky] (ni? me)]

gfx.webrender.all: true
layers.acceleration.force-enabled: true

That may be the key here.

Comment 18

[Martin Stránský [:stransky] (ni? me)]

It's here:

490│ bool GLContextEGL::SwapBuffers() {
491│ EGLSurface surface =
492│ mSurfaceOverride != EGL_NO_SURFACE ? mSurfaceOverride : mSurface;
493│ if (surface) {
494├> return mEgl->fSwapBuffers(EGL_DISPLAY(), surface);
495│ } else {
496│ return false;
497│ }
498│ }

76-trunk-gtk3/src-wayland/gfx/gl/GLLibraryEGL.h[m:226

The EGL_DISPLAY() seems to be invalid.

Comment 19

[russianneuromancer]

Still reproducible with today Nightly build (Gnome Shell 3.30, layers acceleration forced, webrender forced).

Comment 20

[Martin Stránský [:stransky] (ni? me)]

Yes, I'm going to look at it.

Comment 21

[Dan Callahan [:callahad]]

With WebRender, I cannot reproduce on today's Nightly (20190404215521).

Without WebRender, I see the same crash as always: libwayland-client.so.0.3.0@0xac40

Comment 22

[Martin Stránský [:stransky] (ni? me)]

I think I have a patch for it.

Comment 23

[Martin Stránský [:stransky] (ni? me)]

Attachment: Bug 1517205 - Make nsWaylandDisplay() global, r=lsalzman

Lazilly create nsWaylandDisplay objects and remove them at Firefox quit.

nsWaylandDisplay objects should stay as global objects and don't be created/released.
The creation/removal wastes resources on server side as the wl_registry objects at nsWaylandDisplay has to be stored at server
side and can't be removed until firefox ends [1] anyway.

Also the removed nsWaylandDisplay causes crashes when display
topology changes due to the global nature of the wl_registry.

Comment 25

[russianneuromancer]

Also the removed nsWaylandDisplay causes crashes when display
topology changes due to the global nature of the wl_registry.

I wonder if Bug 1515467 have similar nature?

Comment 26

[Martin Stránský [:stransky] (ni? me)]

(In reply to russianneuromancer from comment #25)

Also the removed nsWaylandDisplay causes crashes when display
topology changes due to the global nature of the wl_registry.

I wonder if Bug 1515467 have similar nature?

Yes, that's possible.
