The service channel D-Bus interface aims to be a "back door" for
services that needs special casing in Mutter, e.g. have custom private
protocols only meant to be used by that particular service.
There are currently no special casing implemented; only the basic
service channel infrastructure is added. There is a single method on the
interface, that is meant to eventually be used by
xdg-desktop-portal-gnome to open a Wayland connection with a private
protocol needed for the portal backend's rather special window
management needs.
The service channel Wayland client works by allowing one instance of
each "type", where each time needs to be defined to work in parallel. If
a new service client connects, the old one will be disconnected.
MetaWaylandClient's are used to manage the service clients, and are
assigned the service client type.

One can add a wl_global filter to a wl_display instance, which can be
used to decide what clients should see what globals. This has so far
been used to limit a Xwayland specific protocol extension to only
Xwayland. In order to expand the logic about what globals are filtered
to what clients, introduce a filter manager and port the Xwayland
specific protocol filter to this new manager.
Tests are added, using a new dummy protocol, to ensure that filtering is
working as expected.

It only tests indirect clients, i.e. not the subprocess part, so far,
but tests explicitly terminating by destroying the MetaWaylandClient
object, as well as the client self terminating and the signal being
emitted.

This API creates a "client" then later sets up a wl_client and returns a
file descriptor some Wayland client can connect to. It's meant to be
used as a method other than WAYLAND_SOCKET and process launching, e.g.
passing a file descriptor via a D-Bus API.

On X11, the stage itself is backed by an XWindow, and moving the
input focus elsewhere will bypass any Clutter-level grabs.
This effectively allows newly opened windows to steal the focus
from gnome-shell itself, which is clearly undesirable. To prevent
that, only allow moving the X11 focus to a Window when no grab is
in place, just like commit 50e89e376 did for the stage focus.
But particularly the updating of x11_display->focus_xwindow is not
prevented. Since it's more consistent to the MetaDisplay/MetaX11Display
dual focus tracking and across Wayland/X11 backends, ensure the X11
input focus is actually set on the last focus Window after the
grabs are gone and windows became interactable again.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2832>
This patch unfortunately results in situations where it is intended
that the focus change happens while a grab is present (e.g. Alt+tab
popup), resulting in confused focus state.
This commit is reverted in order to try a similar approach at a
different level.
This reverts commit 7531669b4f.

We used it to retrieve a Display, and convert between Atoms and

same than GDK's anyways) and use XInternAtom/XGetAtomName for
these conversions.

We didn't always set an implementation, when the foreign toplevel wasn't

Windows that are decorated may get configure requests before
the frames client created a corresponding frame window and Mutter
reparented the window.
Since the configure request results in the buffer size being
used to update the window size and the window does not have a
buffer yet, these requests could mistakenly result in the client
window being given a minimal size.
In these situations, do not use the buffer size but the given
size. The window still has to undergo frame creation and
reparenting before being shown for the first time.

This used to be implicitly done by popups using a META_GRAB_OP_WAYLAND_POPUP
MetaDisplay grab. Since commit a8cd488c6f Wayland popups no longer do that,
so the keyboard focus was simply unset if a popup was destroyed while having
the keyboard focus.
Trigger a full input focus sync, so the correct MetaWaylandKeyboard focus
surface is looked up from the focused MetaWindow.

On one hand, this used to be handled generically in all the paths that
changed the MetaWaylandPointer focus surface, induced by user interaction
or not.
On the other hand, just listening for crossing events is not sufficient
since those also do happen programmatically. We must only listen to
crossing events that have a physical source device, meaning this was
created through user interaction.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/888
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2828>
On Wayland sessions, this handling is unnecessary and even prone
to confusion (e.g. crossing serials are only ignored in X11-exclusive
paths, so this handling competes directly with that in MetaWaylandPointer).
Avoid it entirely there, so MetaWaylandPointer can figure out
sloppy/mouse mode focus for all Wayland/Xwayland surfaces.

In GTK this is only used for GTK clipboard/DnD selections, and
finding out whether there is a compositing manager in charge.
In Mutter, we manage our own clipboard/DnD selections, and don't
perform any rendering through GTK in the Mutter process.
So there's no special reason to let these events go through GTK,
and (related to xwayland-on-demand?) there may be race conditions
in the handling of the second feature.
There's a chance this race condition may be in Mutter, but it
does not sound worth to chase this race condition when we can
let GTK ignore these events. And it does not make sense to "fix"
gtk3 for this Mutter-only condition, when we intend to eventually
avoid it.
So, take the easy path and ignore these events.

The first monitor in stacking tests is the primary monitor but that
doesn't have to stay this way forever. Instead of special casing the
name "primary" to refer to whatever monitor happens to be the primary
monitor, we add an `assert_primary_monitor` command to verify that the
monitor that should be the primary monitor actually is.

New add_monitor command for adding secondary monitors. Support setting

bind_output() creates output interface resource, but does not
set implementation for it when wayland_output->monitor is NULL.
However, when the wayland library is running wl_closure_invoke(),
it expects the implementation to be non-NULL, and if not, it just
segfaults mutter by NULL pointer dereference.
This commit tries to address this issue by setting an implementation
when wayland_output->monitor is NULL. This could help prevent crash
when resuming from suspend or hotplugging displays.

The order of dependencies influences the order of -L arguments to gcc/ld,

ClutterActions now no longer receive their events via
clutter_actor_event(), instead they get special treatment by the stage
now. Make the MetaGestureTracker work with this and stop emitting events
directly to Clutter via clutter_actor_event(), but instead let them get
through to Clutter (but still not to Wayland).

The previous logic tried to keep the position of the top left corner of
the window relative to the top left corner of the monitor. This allowed
the window to move out of the target monitor. This change keeps the
proportions of the distance between the window and the monitor borders
instead if possible. Otherwise it keeps the relative position of the
center of the window clamped to [0,1] to make sure the window lands on
the right output.
This also slightly changes what monitor is considered to be on: the
monitor which contains the center of the window and, if the center is on
no monitor, the monitor wich overlaps the most with the window.

So we can remove the additional `next_fb` and `current_fb` pointers from

As with GAMMA_LUT, track whether privacy screen state has been pushed to

As with CRTC GAMMA_LUT, we're moving towards making the entity managing
KMS updates aware if there are any changes to be made, and whether KMS
updates are actually needed or not, and for privacy screen changes, this
means we need to communicate whether the privacy screen state is valid
or not. This allows the caller to create any needed MetaKmsUpdate.

Running each stacking test as a separate installed-test is analogous to

While completely untested, at least this makes it work "in theory"
again. Before it'd listen to signals on the stage, but have an incorrect
type signature to handle the test paint procedures, meaning it'd
probably crash or cause memory corruptions.
What was needed was a signal which in the callback the test could call
some cogl functions to paint on the framebuffer. While there is no such
signal on the stage, and the ClutterActor::paint signal (which they
probably used in the past) is long gone, lets add a "test actor" that is
just a wrapper that adds that paint signal with a paint context.
The tests that need it are changed to add this actor to the stage, and
to listen to the paint signal on the actor instead of incorrectly
listening on stage signals.

At least indirectly, this is set as object qdata while the
window drag is ongoing, and reset/reconstructed if needed.
Consequently, this edge data does not need to be stored in
the MetaDisplay struct anymore.

Since MetaWindowDrag took a lot of this code to handle window drags

Flip the switch in using MetaWindowDrag, leaving display grab
ops and a bunch other code unused. Some places checked the grab op
and/or window in complex ways, others just checked for grab existence

This helper object (and the whole window drag operation) will be

Since SSD X11 windows require synchronization between frame and client
windows on resizes, updates do not always happen immediately but in
control of external factors (i.e. when both windows become to have
a coherent size).
This method will be used to update the window position between
resize/sync operations.

This compositor-side object will single-handedly drive a window
drag operation. Currently, this largely copies meta_display_begin_grab_op
and meta_display_end_grab_op, except grabbing is done through a
ClutterGrab instead of direct meta_backend_grab_device() calls. This
also means that the switch from passive to active keyboard grabs is
handled differently.
Currently, this object is dormant. It requires moving more code from
other places to become a fully functional replacement.

We only allow partial grabs in the case of a keyboard-type MetaGrabOp
happening while the pointer cannot be grabbed. In that case, it's not
a big stretch to unconditionally ungrab the pointer device at the time
of undoing the grab, as it will be always ineffective (not even implicit
grabs on frame windows can happen now, inside Mutter).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2683>
This is no longer necessary, since the SSD frames are no longer
part of Mutter process, so it is not the MetaX11Display connection
which holds the implicit grab when a mouse button is pressed over
a window frame (say, to start a drag).
As the SSD frames client communicates the same way than CSD windows
for window operations, it is also expected to undo its implicit
grab before requesting a window move/resize operation.

Now that it is called from a single place, there's a few arguments
that are unnecessary:
- button and modifiers are unused
- already_grabbed was originally added to handle grab transitions between

longer necessary now
- frame_action can be passed through the META_GRAB_OP_WINDOW_FLAG UNCONSTRAINED
