This used to be set on meta_compositor_manage(), but only if there is a
MetaX11Display. Given meta_display_init_x11() is Wayland only, and we can
always assume compositing to be enabled, just have it invariably set after
the X server is up.

The check-alive feature is there for the user to be able to terminate
frozen applications more easily. However, sometimes applications are
implemented in a way where they fail to be reply to ping requests in a
timely manner, resulting in that, to the compositor, they are
indistinguishable from clients that have frozen indefinitely.
When using an application that has these issues, the GUI showed in
response to the failure to respond to ping requests can become annoying,
as it disrupts the visual presentation of the application.
To allow users to work-around these issues, add a setting allowing them
to configure the timeout waited until an application is considered
frozen, or disabling the check completely.

The cancellable of a request might already be cancelled by the time
the cancelled_cb is connected resulting in finish_cb being called via
ca_context_cancel before g_cancellable_connect returns. In this case
the request that is written to has already been freed.

There are two surface roles owning a MetaWindow: MetaWaylandShellSurface
(basis of MetaWaylandXdgToplevel, MetaWaylandXdgPopup,
MetaWaylandWlShellSurface, etc), and MetaXwaylandSurface.
With these two role types, the MetaWindow has two different types of
life times. With MetaWaylandShellSurface, the window is owned and
managed by the role itself, while with MetaXwaylandSurface, the
MetaWindow is tied to the X11 window, while the Wayland surface and its
role plays more the role of the backing rendering surface.
Before, for historical reasons, MetaWindow was part of
MetaWaylandSurface, even though just some roles used it, and before
'wayland: Untie MetaWindowXwayland lifetime from the wl_surface' had
equivalent life times as well. But since that commit, the management
changed. To not have the same fied in MetaWaylandSurface being managed
in such drastically different ways, rearrange it so that the roles that
has a MetaWindow themself manages it in the way it is meant to; meaning
MetaWaylandShellSurface practically owns it, while with Xwayland, the
existance of a MetaWindow is tracked via X11.

If a window already is being pinged, it doesn't make sense to send more
pings to the window, instead we should just wait for that answer or
timeout until we send a new one.

Using a timestamp twice in a row (e.g. when activating two windows in
response to the same event or due to other bugs) will break the window
detection and show a close dialog on the wrong window. This is a grave
error that should never happen, so check every timestamp before sending
the ping for uniqueness and if the timestamp was already used and its
ping is still pending, log a warning message and don't send the ping.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/891
Increase the number of checks whether a window is still responsive and
ping windows on every call to `meta_window_focus()` instead of
`meta_window_activate_full()`. This ensures the window is also pinged in
case normal interaction like clicks on the window happen and a close
dialog will eventually get shown.

When an X11 window requests an initial workspace, we currently trust
it that the workspace actually exists. However dynamic workspaces
make this easy to get wrong for applications: They make it likely
for the number of workspaces to change between application starts,
and if the app blindly applies its saved state on startup, it will
trigger an assertion.
Make sure that we pass valid parameters to set_workspace_state(),
and simply let the workspace assignment fall through to the default
handling otherwise.

Most usually, applications either expose clipboard content either as text
or as images, so the prioritization here is pointless. However there's some
outliers like LibreOffice Calc which exports content as both image and text
formats (besides other internal ones).
In that mixed case, we probably prefer to keep text formats, rather than
image based ones.

As we now call `meta_wayland_compositor_repick()` when the effects are
complete for Wayland surfaces, we can safely remove the Wayland specific

Currently, `meta_frame_get_mask()` and `meta_ui_frame_get_mask()` will
return the frame mask applied to the current frame size, by querying the
frame themselves.

take a rectangle representing the size at which the frame mask should be
rendered.

In Wayland, window configuration is asynchronous. Window geometry is
constrained, the constrained geometry is sent to the client, and the
client will adapt its surface and acknowledge the configuration. When
acknowledged, we shouldn't reconstrain again, as that may invalidate the
constraint calculated for the configured size.

The intention of meta_window_wayland_move_resize() is to finish a

While most of the code to compute a window's layer isn't explicitly
windowing backend specific, it is in practice: On wayland there are
no DESKTOP windows(*), docks(*) or groups.
Reflect that by introducing a calculate_layer() vfunc that computes
(and sets) a window's layer.
(*) they shall burn in hell, amen!
https://gitlab.gnome.org/GNOME/mutter/merge_requests/949
Most of the layer computation that the stack does actually depends
on the windowing backend, so we will move it to a vfunc.
However before we do that, split out the bit that will be shared.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/949
When a window that should be stacked above another one is placed in a lower
layer than the other window, we currently allow promoting it to the higher
layer when it has a "transient type". We should do the same when the window
is an actual transient of the other window.
This is particularly relevant for wayland windows, where types play a
much smaller role: Transient windows like non-modal dialogs (and since
commit 666bef7a, popup windows as well) currently end up underneath their
always-on-top parent.

Add an assert that we don't have a MetaWindow::monitor pointer that
points to an old MetaLogicalMonitor. After this, and the other
monitors-changed callbacks have been called, the old MetaLogicalMonitor
will be destoryed, thus if we didn't update the pointer here, we'll
point to freed memory, and will eventually crash later on.

This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

Add an adjust_fullscreen_monitor_rect virtual method to MetaWindowClass

for a workaround related to fullscreen games under Xwayland.

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.

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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/821
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.

Instead of open coding the X11 focus management in display.c, expose

We have a "setup" phase, used internally to initialize early the x11
side of things like the stack tracker, and an "opened" phase where
other upper parts may hook up to. This latter phase is delayed during
initialization so the upper parts have a change to connect to on
plugin creation.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/771
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.

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
MutterClutterBackendX11, this extends to device manager, input devices,

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.

When double clicking to un-maximize an X11 window under Wayland, there
is a race between X11 and Wayland protocols and the X11 XConfigureWindow
may be processed by Xwayland before the button press event is forwarded
via the Wayland protocol.
As a result, the second click may reach another X11 window placed right
underneath in the X11 stack.
Make sure we do not forward the button press event to Wayland if it was
handled by the frame UI.
https://gitlab.gnome.org/GNOME/mutter/issues/88
Some meta_later operations may happen across XWayland being shutdown,
that trigger MetaStackTracker queries for X11 XIDs. This crashes as
the MetaX11Display is already NULL.

The Xwayland manager now has 4 distinct phases:
- Init and shutdown (Happening together with the compositor itself)
- Start and stop
In these last 2 phases, handle orderly initialization and shutdown
of Xwayland. On initialization We will simply find out what is a
proper display name, and set up the envvar and socket so that clients
think there is a X server.
Whenever we detect data on this socket, we enter the start phase
that will launch Xwayland, and plunge the socket directly to it.
In this phase we now also set up the MetaX11Display.
The stop phase is pretty much the opposite, we will shutdown the
MetaX11Display and all related data, terminate the Xwayland
process, and restore the listening sockets. This phase happens
on a timeout whenever the last known X11 MetaWindow is gone. If no
new X clients come back in this timeout, the X server will be
eventually terminated.
The shutdown phase happens on compositor shutdown and is completely
uninteresting. Some bits there moved into the stop phase as might
happen over and over.
This is all controlled by META_DISPLAY_POLICY_ON_DEMAND and
the "autostart-xwayland" experimental setting.

When rushing to unmanage X11 windows after the X11 connection is closed/ing,

What "restart" means is somewhat different between x11 and wayland
sessions. A X11 compositor may restart itself, thus having to manage
again all the client windows that were running. A wayland compositor
cannot restart itself, but might restart X11, in which case there's
possibly a number of wayland clients, plus some x11 app that is
being started.
For the latter case, the assert will break, so just make it
conditional. Also rename the function so it's more clear that it
only affects X11 windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
If the display is closed prematurely, go through all windows that
look X11-y and remove them for future calculations. This is not
strictly needed as Xwayland should shut down orderly (thus no client
windows be there), but doesn't hurt to prepare in advance for the
cases where it might not be the case.

We don't strictly need it for wayland compositors, yet there are

Commit 09bab98b1e tried to avoid several workspace changes while in
window construction, but it missed a case:
If we have a window on a secondary monitor with no workspaces enabled
(so it implicitly gets on_all_workspaces = TRUE without requesting it)
and trigger the creation of a second window that has the first as
transient-for, it would first try to set the first workspace than the
transient-for window and then fallback to all/current workspace.
After that commit we only try to set the same workspace than the
transient-for window, but it gets none as neither is on a single workspace,
nor did really request to be on all workspaces.
Fixes crashes when opening transient X11 dialogs in the secondary monitor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/714
We first set the workspace to the transient-for parent's, and then
try to set on the current workspace. If both happen, we double the
work on adding/removing it from the workspace, and everything that
happens in result.

bar, as the animation results in a number of xdg_popup being created
and destroyed to handle the animation.

On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.
However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.
Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/647
Some special modifiers (typically "Control_L" used for locate-pointer in
mutter/gnome-shell or "Super_L" for overlay) must be handled separately
from the rest of the key bindings.
Add a new flag `META_KEY_BINDING_NO_AUTO_GRAB` so we can tell when
dealing with that special keybinding which should not be grabbed
automatically like the rest of the keybindings, and skip those when
changing the grabs of all keybindings.
