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
code to do the same from `meta_window_show()`.

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.
To be able to get the frame mask at an arbitrary size, change the API to
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
move-resize requested previously, e.g. by a state change, or a
interactive resize. Make the function name carry this intention, by
renaming it to meta_window_wayland_finish_move_resize().

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.

Override-redirect windows have no workspace by default, and can't be parent

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
it as a single function with similar arguments to its MetaDisplay
counterpart. This just means less X11 specifics in display.c.

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

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.
Return a NULL window in that case, as in "unknown stack ID".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
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.

Using the master device, as we did, won't yield the expected result when

The device ID is kind of pointless on Wayland, so it might be better to

As per commit 040de396b, we don't try to grab when shortcuts are inhibited,
However, this uses the focus window assuming that it is always set, while this
might not be the case in some scenarios (like when unsetting the focus before
requesting take-focus-window to acquire the input).
So allow the button grab even if the focus window is not set for the display

On Wayland, if a client issues a inhibit-shortcut request, the Wayland
compositor will disable its own shortcuts.
We should also disable the default handler for the button grab modifier
so that button events with the window grab modifiers pressed are not
caught by the compositor but are forwarded to the client surface.
That also fixes the same issue with Xwayland applications issuing grabs,
as those end up being emulated like shortcut inhibition.

gnome-shell hardcodes a vertical one-column workspace layout, and

When destroying a window that has a parent, we initially try to focus one of

When we're unfullscreening, we might be returning to a window state that
has its size either managed by constraints (tiled, maximized), or not

maximized) and let the application decide how to size itself.

As per commit 7718e67f, destroying the compositor causes destroying window
actors and this leads to stack changes, but at this point the stack was already
disposed and cleared.
So, clear the stack when any component that could use it (compositor, and X11)
has already been destroyed.
As consequence, also the stamps should be destroyed at later point.

We're currently emitting the 'grab-op-end' signal when the grab prerequisites
are met, but when display->grab_op is still set to a not-NONE value and thus
meta_display_get_grab_op() would return that in the signal callback.
And more importantly when this is emitted, devices are still grabbed.
Instead, emit this signal as soon as we've unset all the grab properties and
released the devices.

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

We use a GtkIconTheme (thus icon-theme, thus xsettings, thus x11) just to
grab a "missing icon" icon to show in place. Relax this requirement that
surfaces for icon/mini-icon will be set, and just let it have NULL here.
It seems better to have the callers (presumably UI layers) aware of this
and set a proper icon by themselves, but AFAICS there is none in sight,
not even plain mutter seems to use MetaWindow::[mini-]icon. Probably
worth a future cleanup.

This explicit ungrab is made to ensure the other X11 display connection

This object takes care of the X11 representation of the window stack,
namely the _NET_CLIENT_LIST and _NET_CLIENT_LIST_STACKING root window

This code has been lifted from src/core/stack.c into src/x11 as it's
dependent on the X11 display availability. This also leaves MetaStack
squeaky clean of x11 specifics.

We'd break the loop for moving attached windows at the first window,
meaning we'd only ever move a single attached dialogs or popup if it was
the first window in the list. This doesn't work out well when there are
multiple popups open, so don't break out of the loop at all until all
windows are potentially moved.
This fixes an issue in gtk4 where one or more non-grabbing popups would
end up unattached if there were more than one and the parent window was
moved.

This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.

When an application stops responding, the shell darkens its windows.
If a window from a not-responding application gets unmanaged
then the shell will currently throw an exception trying to retrieve
the now-dissociated window actor.

in the log.
This commit addresses the problem by making sure the effect is cleaned
up before the actor is disocciated from its window.

When focus stealing prevention kicks in, mutter would set the demand
attention flag on the window.
Focus stealing prevention would also prevent the window from being
raised and focused, which is expected as its precisely its purpose.
Yet, when that occurs, the user expects the window which has just been
prevented from being focused to be the next one in the MRU list, so
that pressing [Alt]-[Tab] would raise and give focus to that window.
This works fine when the window is placed on the primary monitor, but
not when placed on another monitor, in which case the window which has
been denied focus is placed ahead of the MRU list and pressing
[Alt]-[Tab] would leave the focus on the current window.
This is because of a mechanism in `meta_display_get_tab_list()` which
forces the windows with the demand attention flag set to be placed first
in the MRU list when they're placed on a workspace different from the
current one.
But because workspaces apply only to the primary monitor (by default),
the windows placed on other outputs have their workspace set to `NULL`
which forces them ahead of the MRU list by mistake.
Fix this by using the appropriate `meta_window_located_on_workspace()
function to check if the window is on another workspace.

TOUCH_BEGIN or TOUCH_END event happened during the key was pressed.

If an intersection is empty, the (x, y) coordinates are undefined, so
just use the work area and in-progress constrained window rect when
sliding according to the SLIDE_X or SLIDE_Y custom placement rule.

When check_only is TRUE, the constraint should not be applied, just
checked. We failed to comply here when a placed transient window was
to be moved together with its parent, updating the window position
directly even if check_only was TRUE.

If a client maps a persistent popup with a placement rule, then resizes
the parent window so that the popup ends up outside of the parent,
unmanage the popup and log a warning about the client being buggy.

When a parent window is moved, attached windows (attached modal dialogs
or popups) is moved with it. This is problematic when such a window
hasn't been shown yet (e.g. a popup that has been configured but not
shown), as it'll mean we try to constrain an empty window. Avoid this
issue by not trying to auto-move empty windows.
