This is for all intents and purposes the same as

We were just looking at DnD actions which might still be unset at that
point. Instead of doing these heuristics, store the selection type on
the data offer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/845
Requesting a selection with a NULL data source means "unset the clipboard",
but internally we use an unset clipboard as the indication that the
clipboard manager should take over.
Moreover, this unset request may go unheard if the current owner is someone
else than the MetaWaylandDataDevice.
Instead, set a dummy data source with no mimetypes nor data, this both
prevents the clipboard manager from taking over and ensures the selection
is replaced with it.
The MetaSelectionSourceMemory was also added some checks to allow for this
dummy mode.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/793
Instead of taking resource and send/cancel funcs, take a
MetaWaylandDataSource, which exposes all the vfuncs to do the same on the
internal resource.
This has the added side effect that only MetaWaylandDataSource has a
pointer to the wl_resource, which may be unset untimely.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
If a data source is destroyed we first unset the resource, and then try to
unref the related selection source. At this point the only event that might
be emitted by the internal selection machinery is .cancelled, so make sure
we avoid it on destroyed sources.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
We are still poking the mimetypes from the previous selection when creating

If we did a mode set, the gamma may have been changed by the kernel, and
if we didn't also update the gamma in the same transaction, we have no
way to predict the current gamma ramp state. In this case, read the
gamma state directly from KMS.
This should be relatively harmless regarding the race conditions the
state prediction was meant to solve, as the worst case is we get none or
out of date gamma ramps; and since this is for when gamma ramps are not
updated at mode setting time, we'd get intermediate gamma state to begin
with, so it's not worse than what we currently do anyway.

A frame callback without damage is still expected to be responded to.
Implement this by simply queuing damage if there are any frame callbacks

For the most part, a MetaWindow is expected to live roughly as long as
the associated wl_surface, give or take asynchronous API discrepancies.
The exception to this rule is handling of reparenting when decorating or
undecorating a window, when a MetaWindow on X11 is made to survive the
unmap/map cycle. The fact that this didn't hold on Wayland caused
various issues, such as a feedback loop where the X11 window kept being
remapped. By making the MetaWindow lifetime for Xwayland windows being
the same as they are on plain X11, we remove the different semantics
here, which seem to lower the risk of hitting the race condition causing
the feedback loop mentioned above.
What this commit do is separate MetaWindow lifetime handling between
native Wayland windows and Xwayland windows. Wayland windows are handled
just as they were, i.e. unmanaged together as part of the wl_surface
destruction; while during the Xwayland wl_surface destruction, the
MetaWindow <-> MetaWaylandSurface association is simply broken.

We get implicit, thus auto-removed, transitions, then manage them
manually by stopping them and emitting "completed" signals. This doesn't
work since they are removed and freed when stopped. To be able to emit
the "completed" signal, hold a reference while stopping, so that we
still can emit the signal as before.

Dropping the grab has the side effect that the pointer will be re-picked,
and it might find another surface with a pointer constraint. If that were
the case, the focus change would try to add the pointer constraint before
the now old focus surface released its own.
Just invert these operations, so the constraint is unset before the repick
that might enable another pointer constraint.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/779
Just like sync_focus_surface() does, we shouldn't set a focus surface while

We can't just update the state of the connector and CRTC from KMS since
it might contain too new updates, e.g. from a from a future hot plug. In
order to not add ad-hoc hot plug detection everywhere, predict the state
changes by looking inside the MetaKmsUpdate object, and let the hot-plug
state changes happen after the actual hot-plug event.
This fixes issues where connectors were discovered as disconnected while
doing a mode-set, meaning assumptions about the connectedness of
monitors elsewhere were broken until the hot plug event was processed.

Instead of storing the result of meta_prop_get_latin1_string() into
a temporary string value, g_strdup-ing that temp value storing the
g_strdup result into window->sm_client_id and then g_free-ing the
temporary string, we can pass window->sm_client_id as the place where
meta_prop_get_latin1_string() stores its result, since the result
from meta_prop_get_latin1_string() is itself a g_strdup-ed string,
so there is no need to g_strdup it again.
Note this drops the check to only issue the
"Window %s sets SM_CLIENT_ID on itself ..." warning once. This check is
not necessary as update_sm_hints() is only called once at window
creation time and is never called again.

Clutter actors might emit property changes in dispose, while unparenting.
However we assume that the ::destroy signal is the last one we emit for an
actor, and that starting from this moment the object is not valid anymore,
and so we don't expect any signal emission from it.
To avoid this, freeze the object notifications on an actor during its
disposition, just before the ::destroy signal emission.
Update the actor-destroy test to verify this behavior.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/769
Clutter actors unset their parent on dispose, after emitting the ::destroy
signal, however this could cause ::parent-set signal emission. Since we
assume that after the destruction has been completed the actor isn't valid
anymore, and that during the destroy phase we do all the signal / source
disconnections, this might create unwanted behaviors, as in the signal
callbacks we always assume that the actor isn't in disposed yet.
To avoid this, don't emit ::parent-set signal if the actor is being
destroyed.
Update the actor-destroy test to verify this behavior.

Mutter issues a synchronous grab on the pointer for unfocused client
windows to be able to catch the button events first and raise/focus
client windows accordingly.
When there is a synchronous grab in effect, all events are queued until
the grabbing client releases the event queue as it processes the events.
Mutter does release the events in its event handler function but does so
only if it is able to find the window matching the event. If the window
is a shell widget, that matching may fail and therefore Mutter will not
release the events, hence causing a freeze in pointer events delivery.
To avoid the issue, make sure we sync the pointer events in case we
can't find a matching window.

It was not the lack of forcing the shadow fb that caused slowness, but
rather due to the method the shadow fb content was copied onto the
scanout fb. With 'clutter: Use cogl_blit_framebuffer() for shadow FB'
we'll use a path that shouldn't be slow when copying onto the scanout
fb.
Also 437f6b3d59 accidentally enabled
shadow fb when using hw accelerated contexts, due to the cap being set
to 1 in majority of drivers. While the kernel documentation for the
related field says "hint to userspace to prefer shadow-fb rendering",
the name of the hint when exposed to userspace is
DRM_CAP_DUMB_PREFER_SHADOW, thus should only be taken into consideration
for dumb buffers, not rendering in general.
This reverts commit 437f6b3d59.

The commit 'renderer/native: Use shadow fb on software GL if preferred'

Now instead always force it for llvmpipe and other software rendering
backends, and otherwise just query the drm device (i.e.
DRM_CAP_DUMB_PREFER_SHADOW).

Since the recent clutter-content work, legacy scaling (in contrast
to the new stage-view-scaling) only applies to surfaces that belong
to a window. This broke scaling of DnD surfaces.
As a workaround, apply the same scaling on DnD-surface-actors until
we use stage-view-scaling by default and can remove this again.
Also: small corrections of geometry calculation
https://gitlab.gnome.org/GNOME/mutter/merge_requests/780
This allows us to implement more sophisticated logic for the different
cases. For DnD surfaces, use the geometry scale of the monitor where
the pointer is, instead of incorrectly assuming '1' as it was before.

With the addition of the locate-pointer special keybinding (defaults to
the [Control] key), we have now two separate special modifier keys which
can be triggered separately, one for the locate-pointer action and
another one for overlay.
When processing those special modifier keys, mutter must ensure that the
key was pressed alone, being a modifier, the key could otherwise be part
of another key combo.
As result, if both special modifiers keys are pressed simultaneously,
mutter will try to trigger the function for the second key being
pressed, and since those special modifier keys have no default handler
function set, that will crash mutter.
Check if the handler has a function associated and treat the keybinding
as not found if no handler function is set, as with the special modifier
keys.
https://gitlab.gnome.org/GNOME/mutter/issues/823
The `process_event()` would check for a existing keybinding handler and
abort if there is none, however the test is done after the handler had
been accessed, hence defeating the purpose of the check.
Move the check to verify there is an existing keybinding handler before
actually using it.

When starting standalone mutter and running using the native backend, we
always fall back on using the us pc105 keyboard layout. This can be very
frustrating if one is used to using some other keyboard layout, such as
dvorak, causing keyboard fumbling everytime when doing something with
standalone mutter.
Avoid this involuntary fumbling by having the default plugin query
localed what layout the user has actually configured the machine to
operate using. It doesn't add any keymap selection user interface, so
it'll always use the first one it encounters.

The commit f2f4af0d50 missed one situation
where mutter does things differently, i.e. changes what surface actor is
associated with a given window actor: reparenting a Xwayland window when
changing whether it is decorated.
To summarize, there are three types of window actors:
X11 window actors - directly tied to the backing X11 window. The
corresponding surface actor is directly owned by the window actor and
will never change.
Wayland window actors - gets its surface actor from MetaWaylandSurface
at construction. A single MetaWaylandSurface may create and destroy
multiple window actors over time, but a single window actor will never
change surface actor.
Xwayland window actors - a mix between the above two types; the window
corresponds to the X11 window, and so does the window actor, but the
surface itself comes from the MetaWaylandSurface.
Normally when a X11 window is unmapped, the corresponding MetaWindow is
unmanaged. With Xwayland, this happens indirectly via the destruction of
the wl_surface. The exception to this is windows that are reparented
during changing their decoration state - in this case on plain X11, the
MetaWindow stays alive. With Xwayland however, there is a race
condition; since the MetaWindow is tied to the wl_surface, if we receive
the new surface ID atom before the destruction of the old wl_surface,
we'll try to associate the existing MetaWindow and MetaWindowActor with
the new wl_surface, hitting the assert. If the surface destruction
arrives first, the MetaWindow and MetaWindowActor will be disposed, and
the we wouldn't hit the assert.
To handle this race gracefully, reinstate handling of replacing the
surface actor of an existing window actor, to handle this race, as it
was handled before.
Eventually, it should be reconsidered whether the MetaWindow lifetime is
tied to the wl_surface or if it should be changed to be consistent with
plain X11, as this re-exposes another bug where the X11 client and
mutter will enter a feedback loop where the window is repeatedly
remapped. See https://gitlab.freedesktop.org/xorg/xserver/issues/740.

When starting a DnD operation, mutter would remove keyboard focus from
the client, only to restore it on the data offer destroy.
However, if the DnD fail, the keyboard focus is not restored, leaving
the user unable to type in the focused window, even after clicking in
the window.
That issue would show only on first attempt, as further DnD attempts
would destroy the previous data offer which would also restore the
keyboard focus.
Make sure we restore the keyboard focus on drag end as well.
https://gitlab.gnome.org/GNOME/mutter/issues/747
On drag start, `data_device_start_drag()` issues a keyboard grab, which
in turn will unset the current input focus.
There is not need to unset the input focus in `data_device_start_drag()`
as this is redone in `meta_wayland_keyboard_start_grab()`
https://gitlab.gnome.org/GNOME/mutter/issues/747
Currently, Clutter does picking by drawing with Cogl and reading
the pixel that's beneath the given point. Since Cogl has a journal
that records drawing operations, and has optimizations to read a
single pixel from a list of rectangle, it would be expected that
we would hit this fast path and not flush the journal while picking.
However, that's not the case: dithering, clipping with scissors, etc,
can all flush the journal, issuing commands to the GPU and making
picking slow. On NVidia-based systems, this glReadPixels() call is
extremely costly.
Introduce geometric picking, and avoid using the Cogl journal entirely.
Do this by introducing a stack of actors in ClutterStage. This stack
is cached, but for now, don't use the cache as much as possible.
The picking routines are still tied to painting.
When projecting the actor vertexes, do it manually and take the modelview
matrix of the framebuffer into account as well.

If window decoration is modified within a short period of time, mutter
sometimes starts processing the second request before the first
UnmapNotify event has been received. In this situation, it considers
that the window is not mapped and does not expect another UnmapNotify /
MapNotify event sequence to happen.
This adds a separate counter to keep track of the pending reparents. The
input focus is then restored when MapNotify event is received iff all
the expected pending ReparentNotify events have been received.

Threaded swap wait was added for using together with the Nvidia GLX
driver due to the lack of anything equivalent to the INTEL_swap_event
GLX extension. The purpose was to avoid inhibiting the invocation of
idle callbacks when constantly rendering, as the combination of
throttling on swap-interval 1 and glxSwapBuffers() and the frame clock
source having higher priority than the default idle callback sources
meant they would never be invoked.
This was solved in gbz#779039 by introducing a thread that took care of
the vsync waiting, pushing frame completion events to the main thread
meaning the main thread could go idle while waiting to draw the next
frame instead of blocking on glxSwapBuffers().
As of https://gitlab.gnome.org/GNOME/mutter/merge_requests/363, the
main thread will instead use prediction to estimate when the next frame
should be drawn. A side effect of this is that even without
INTEL_swap_event, we would not block as much, or at all, on
glxSwapBuffers(), as at the time it is called, we have likely already
hit the vblank, or will hit it soon.
After having introduced the swap waiting thread, it was observed that
the Nvidia driver used a considerable amount of CPU waiting for the
vblank, effectively wasting CPU time. The need to call glFinish() was
also problematic as it would wait for the frame to finish, before
continuing. Due to this, remove the threaded swap wait, and rely only on
the frame clock not scheduling frames too early.

If an application provides its window icon via wmhints, then mutter
loads the pixmap specified by the application into a cairo xlib surface. When
creating the surface it specifies the visual, indirectly, via an XRender
picture format.
This is suboptimal, since XRender picture formats don't have a way to specify
16bpp depth, which an application may be using.
In particular, applications are likely to use 16bpp depth pixmaps for their
icons, if the video card offers a 16bpp framebuffer/root window.
This commit drops the XRender middleman, and just tells cairo a visual to use
directly.

This currently uses a hack where it pushes a CoglFramebuffer backed by a

window.

We are really more interested in when a window is damaged, rather than

And add the necessary glue so those initialize a X11 clutter backend.
This should get Clutter tests that are dependent on windowing to work
again, thus they were enabled back again.

The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendNative, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

After the introduction of locate-pointer (commit 851b7d063 -
“keybindings: Trigger locate-pointer on key modifier”), inhibiting
shortcuts would no longer forward the overlay key to the client.
Restore the code that was inadvertently removed so that inhibiting
shortcuts works on the overlay key again.

Geometry scale is applied to each surface individually, using
Clutter scales, and not only this breaks subsurfaces, it also
pollutes the toolkit and makes the actor tree slightly too
fragile. If GNOME Shell mistakenly tries to set the actor scale
of any of these surfaces, for example, various artifacts might
happen.
Move geometry scale handling to MetaWindowActor. It is applied
as a child transform operation, so that the Clutter-managed
scale properties are left untouched.
In the future where the entirety of the window is managed by a
ClutterContent itself, the geometry scale will be applied
directly into the transform matrix of MetaWindowActor. However,
doing that now would break the various ClutterClones used by
GNOME Shell, so the child transform is an acceptable compromise
during this transition.

meta_shaped_texture_update_area() is a private function that
is exposed in the public headers. It is not used anywhere
outside Mutter, and should really be in the private header.
Move it to the private header.

Now that MetaShapedTexture is not a ClutterActor anymore, it does
not make sense to make it a MetaCullable semi-implementation. This
is, naturally, a responsibility of MetaSurfaceActor, since now
MetaShapedTexture is a ClutterContent and as such, it only cares
about what to draw.
Move the MetaCullable implementation of MetaShapedTexture to
MetaSurfaceActor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
By implementing ClutterContent, it is expected that
MetaShapedTexture can draw on any actor. However,
right now this is not possible, since it assumes
that the drawing coordinates and sizes of the actor
are synchronized with its own reported width and
height.
It mistakenly draws, for example, when setting an
actor's content to it. There is no way to trigger
this wrong behavior right now, but it will become
a problem in the future where we can collect the
paint nodes of MetaShapedTexture as part of other
ClutterContent implementations.
Use the allocation box passed by the actor to draw
the pipelines of MetaShapedTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Now that MetaShapedTexture is a ClutterContent implemetation that
is aware of its own buffer scale, it is possible to simplify the
event translation routines.
Set the geometry scale in MetaSurfaceActor, and stop adjusting the
surface scale when translating points. Also remove the now obsoleted
meta_wayland_actor_surface_calculate_scale() function.

MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore

With the addition of xauth support (commit a8984a81c), Xwayland would
rely only on the provided cookies for authentication.
As a result, running an Xclient from another VT (hence without the
XAUTHORITY environment variable set) would result in an access denied.
The same on X11 is granted because the local user is automatically
granted access to Xserver by the startup scripts.
Add the local user to xhost at startup on Xwayland so that the user can
still run a client by setting the DISPLAY as long as it's the same user
on the same host.

A base type shouldn't know about sub types, so let MetaDisplay make
the correct choice of what type of MetaCompositor it should create. No
other semantical changes introduced.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/727
Introduce MetaCompositorX11, dealing with being a X11 compositor, and
MetaCompositorServer, being a compositor while also being the display
server itself, e.g. a Wayland display server.
