In preparation of replacing the configuration system with one working
with high level monitors instead of low level outputs etc, move
configuarion handling code into obviously named function (containing
the word 'legacy'.

A monitor spec object is meant to be used to identify a certain monitor
on a certain output. The spec is unique per actual monitor and connector,
meaning that a monitor that changes from one connector from another
(e.g. HDMI1 to HDMI2) will not be identified as the same. It is meant
to associate for example a configuration entry with an actual monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a "mode spec" concept, meaning to be used as a identifier for an
actual monitor mode. It consists of details making a mode unique, i.e.
the total resolution and refresh rate. This will later be used to get
the actual monitor mode (set of one or more CRTC modes).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add "monitor modes" abstracting the modes set on a monitor. On normal
monitors, this directly maps to the CRTC modes, but on tiled monitors,
a monitor mode can consist modes per tiled output.

Don't try to mirror the physical dimension, since that's a property of
one of the monitors, not of the logical monitor. Callers are changed to

Don't deal with adding/removing tiled Xrandr monitors in the generic
backend, but leave it to the Xrandr backend. The tiled monitor will
itself notify the backend when such a monitor is added and removed.
Tiled Xrandr monitors are now based no MetaMonitor instead of
MetaLogicalMonitor. This means that mirrored tiled monitors will now be
represented correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of using crtcs and outputs to generate logical monitors, use
the ready made monitor abstraction that hides irrelevant things such as
monitor tiling etc.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Generate a set of "monitors" abstracting the physical concepts. Each
monitor is built up of one or more outputs; multiple outputs being
tiled monitors. Logical monitors will later be built from these.

The MetaMonitorMode referred to the mode of a CRTC, and with the future

Add private API for overriding the compositor configuration, i.e. the

Put the monitor xinerama index in a separate struct that is attached to
the logical monitor using g_object_set/get_qdata(). Eventually this

https://bugzilla.gnome.org/show_bug.cgi?id=777732
Don't store logical monitor specific state in an array where the index
from the monitor manager is used as index locally. Instead just use
table associating a logical monitor with a monitor specific state
holder, and store the state in there. This way we don't have the
workspace implementation relying on implementation details of other
units.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of storing the logical monitors in an array and having users
either look up them in the array given an index or iterate using
indices, put it in a GList, and use GList iterators when iterating and
alternative API where array indices were previously used.
This allows for more liberty regarding the type of the logical monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Refactor the tiled monitor assembly code (that constructs a logical
monitor out of tiling information. Part of the reason is to move away

Rewrite check_fullscreen_func to not use indexes (and
offset-index-as-pointer) tricks. This also removes the usage of an API

Move the last piece of monitor grid getter API to the monitor manager

The method used for getting the current logical monitor (the monitor
where the pointer cursor is currently at) depends on the backend type,
so move that logic to the corresponding backends.

Turning a rectangle into a logical monitor also has nothing to do with
the screen (MetaScreen) so move it to MetaMonitorManager which has that

Let the backend initialize the cursor tracker, and change all call
sites to get the cursor tracker from the backend instead of from the
screen. It wasn't associated with the screen anyway, so the API was
missleading.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of keeping around array indexes, keep track of them by storing
a pointer instead. This also changes from using an array (imitating the
X11 behaviour) to more explicit storing.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
To complement the current API which takes an index referencing a
logical monitor in the logical monitor array, add API that takes a
direct reference to the logical monitor itself. The intention is to
replace the usage of the index based API with one that doesn't rely on
internal implementation details.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This is the current equivalent of looking up the logical monitor in the

It was just pointer to the actual list; having to synchronize a list of

The fullscreen monitors state is set given a set of xinerama monitor

Instead of having a way to determine the type of a buffer, add a
realization step that implicitly detects the buffer type. This makes it
possible to both realize (i.e. creating needed objects from the buffer)
and determine the type at the same time, which may be the only possible
way (for example, the only way to know whether a buffer is a EGLStream
is to create the EGLStream from it).

A window manager must select the SubstructureRedirect mask on the root
window to receive the MapRequest from the X11 clients and manage the
windows. Without this event mask set, a window manager won't be able to
map any new window.
The Wayland selection code in mutter can change/clear the event mask on
the requestor window from a XSelectionRequest event when the window is
not managed by mutter/gnome-shell.
A rogue or simply buggy X11 client may send a XConvertSelection() on the
root window and mutter will happily change/clear its own event mask on
the root window, effectively turning itself into a regular X11 client
unable to map any new X11 window from the other X11 clients.
To avoid this, simply check that the requestor window is not the root
window prior to change/clear the event mask on that window.

Commit 5eb5f72 - wayland: Check surface outputs after mapped state

https://bugzilla.gnome.org/show_bug.cgi?id=776036
Commit 4295fdb892 made us skip focusing
all xdg_popups instead of just non-grabbing ones as intended. This
means that when unmanaging a window we might select a xdg_popup window
to focus (in meta_stack_get_default_focus_window() ) but then since we
don't actually focus it we go on unmanaging the focused window which
triggers an assertion, as it should.
To avoid this and still fixing bug 771694 we can make use of the
MetaWindow->input property for non-grabbing xdg_popup windows since
their semantics, in this regard, are the same as no input X11 windows.
This way, when unmanaging a focused window while a xdg_popup is up,
we'll either give focus to the xdg_popup or not select the popup at
all to be focused if it's non-grabbing.

We need to do swap notifications asynchronously from flip events since
these might be processed during swap buffers if we are waiting for the
previous frame's flip to continue with the current.
This means that we might have more than one swap notification queued
to be delivered when the idle handler runs. In that case we must
deliver all notifications for which we've already seen a flip event.
Failing to do so means that if a new frame, that only swaps buffers on
such a swap notification backlogged Onscreen, is started, when later
we get its flip event, we'd notify only an old frame which would hit
this MetaStageNative's frame_cb() early exit:
if (global_frame_counter <= presented_frame_counter)
return;
and we'd never finish the new frame and thus clutter's master clock
would be waiting forever stuck.
https://bugzilla.gnome.org/show_bug.cgi?id=774557
We currently only focus unfocused windows on button press if no

When flush-swap-notify is already queued, we might end up trying to
requeue it, for example when handling flip callbacks inside

will be discarded anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=774923
We might still end up in swap-buffer without the previous flip callback
having been invoked. This can happen if there are two monitors, and we
manage to draw before having all monitor flip callbacks invoked.

A window's unconstrained_rect is essentially just the target rectangle
we hand to meta_window_move_resize_internal() except it's not updated
until the window actually moves or resizes.
As such, for wayland client resizes, since they're async, using
window->unconstrained_rect right after calling move_resize_internal()
to update the grab anchor position on unmaximize doesn't work as it
does for X clients.
To fix this, we can just use the target rectangle for the grab
anchor. Note that comment here was already wrong since it says we
should be taking constraints into account and yet the code used the
unconstrained rect anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
This reverts commit 989ec7fc60.
We now rely on accurately knowing if a window moved and/or resized in
meta_window_move_resize_internal() so the wayland implementation can't
lie any longer.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
In order for the compositor plugin to be able to animate window size
changes properly we need to let it know of the starting and final
window sizes.
For X clients this can be done synchronously and thus with a single
call into the compositor plugin since it's us (the window manager)
who's in charge of the final window size.
Wayland clients though, have the final say over their window size
since it's determined from the client allocated buffer.
This patch moves the meta_compositor_size_change_window() calls before
move_resize_internal() which lets the compositor plugin know the old
window size and freezes the MetaWindowActor.
Then we get rid of the META_MOVE_RESIZE_DONT_SYNC_COMPOSITOR flag
since it's not needed anymore as the window actor is frozen and that
means we can use meta_compositor_sync_window_geometry() as the point
where we inform the compositor plugin of the final window size.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
This will be used to let plugins know when a previous size change
actually becomes effective. This is needed to handle wayland client
resizing properly since, unlike X, it's async.

Normally textures in OpenGL are inverted on the Y axis, and we only
apply our rotation transform when it is not. To make the common case
work as normal, default to assuming textures are Y inverted.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
This commit adds for a new type of buffer being attached to a Wayland
surface: buffers from an EGLStream. These buffers behave very
differently from regular Wayland buffers; instead of each buffer
reperesenting an actual frame, the same buffer is attached over and
over again, and EGL API is used to switch the content of the OpenGL
texture associated with the buffer attached. It more or less
side-tracks the Wayland buffer handling.
It is implemented by creating a MetaWaylandEglStream object, dealing
with the EGLStream state. The lifetime of the MetaWaylandEglStream is
tied to the texture object (CoglTexture), which is referenced-counted
and owned by both the actors and the MetaWaylandBuffer.
When the buffer is reattached and committed, the EGLStream is triggered
to switch the content of the associated texture to the new content.
This means that one cannot keep old texture content around without
copying, so any feature relying on that will effectively be broken.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Add support for inverted Y Wayland buffers. OpenGL textures are by
default inverted, so adding support for EGL_WAYLAND_Y_INVERTED_WL
effectively means adding support for non-inverted, which makes the
MetaShapedTexture apply a transformation when drawing only when querying
EGL_WAYLAND_Y_INVERTED_WL resulted in the response "EGL_FALSE".
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Don't rely on the Cogl layer having Wayland specific paths by
determining the buffer type and creating the EGLImage ourself, while
using the newly exposed CoglTexture from EGLImage API. This changes the
API used by MetaWaylandSurface to make the MetaWaylandBuffer API be
aware when the buffer is being attached. For SHM and EGL buffers, only
the first time it is attached will result in a new texture being
allocated, but later for EGLStream's, more logic on every attach is
needed.

This commit adds support for using a EGLDevice and EGLStreams for
rendering on top of KMS instead of gbm. It is disabled by default; to
enable it pass --enable-egl-device to configure.
By default gbm is first tried, and if it fails, the EGLDevice path is
tried. If both fails, mutter will terminate just as before.

There is no way to pass any backend specific parameters to a
CoglFramebuffer until after it has been allocated by
cogl_framebuffer_allocate() (since this is where the winsys/platform
fields are initialized). This can make it hard to actually allocate
anything, if the platform depends on some backend specific data.
A proper solution would be to refactor the onscreens and framebuffers to
use a GObject based type system instead of the home baked Cogl one, but
that'll be left for another day. For now, allocate in two steps, one to
allocate the backend specific parts (MetaOnscreenNative), and one to
allocate the actual onscreen framebuffer (via
meta_onscreen_native_allocate()).
So far there is nothing that forces this separation, but in the future
there will, for example EGLDevice's need to know about the CRTC in
order to create the EGLSurface.

In another step getting rid of the duplications introduced by Cogl,

Similarly to Weston (where this code originated), there were two errors
in the X11 lockfile handling.
Firstly, after reading 11 characters from the lock file (which could
have been placed by any process), there was no guarantee of
NUL-termination, meaning strtol could've theoretically run off the end
of the string.
Secondly, whilst writing the new lock, the trailing NUL byte was not
correctly accounted for. The size passed as an input to snprintf takes
the maximum size of the string including the trailing NUL, whilst the
return (and the input to write) gives the actual size of the string
without the trailing NUL.
The code did attempt to check the return value, however snprintf returns
the size of the _potential_ string written, before snprintf culls it, so
this was off by one, and the LF was not being written.

The Clutter X11 backend can't drop CLUTTER_PEN_DEVICE and
CLUTTER_ERASER_DEVICE in favor of CLUTTER_TABLET_DEVICE without

Its only purpose was caching settings applying to an stylus/tool, this

Stylus configuration (stylus buttons, pressure) was handled
at the very high level, doing the button and pressure translations
right before sending these to wayland clients.
However, it makes more sense to store these settings into the
ClutterInputDeviceTool itself, and have clutter apply the config
at the lower level so 1) the settings actually apply desktop-wide,
not just in clients and 2) X11 and wayland may share similar
configuration paths. The settings are now just applied whenever
the tool enters proximity, in reaction to
ClutterDeviceManager::tool-changed.
This commit moves all handling of these two settings to
the clutter level, and removes the wayland-specific paths
https://bugzilla.gnome.org/show_bug.cgi?id=773779
And remove the wayland-specific handling. This works for both Wayland and

Wayland popup grabs, unlike other grab types, can be safely cancelled
so there's no reason to deny compositor grab requests if a wayland

Enabling edge scrolling before disabling two finger would result in
edge scrolling not actually being enabled because two finger is still
enabled at the time and we bail out.
This patch moves this logic to common code for both the native and X
backends and fixes it by ensuring that both settings are never set at
the same time and still re-checking if edge scrolling should be
enabled after two finger scrolling gets disabled.
We also simplify the code by not checking for supported/available
settings since the underlying devices will just reject those values
and there isn't anything we can do about it here. It's the UI's job to
only show supported/available settings to users.
https://bugzilla.gnome.org/show_bug.cgi?id=771744
Checking for supported methods isn't needed since libinput will just

Commit fcc7501eb8 had the side-effect of

Instead of re-introducing the fullscreen layer, which we don't need

The keyboard focus semantics for non-grabbing xdg_shell v6 popups is

mutter would remove focus from a toplevel when showing one of its
transient window which is not on top and not focused.
When using xdg_popup without grab as allowed in xdg_shell v6, the popup
wouldn't be focused, and if an intermediate event occurs before the

We shouldn't cancel the pointer grab when there is a compositor grab,
since that'd break things like drag-n-drop via the overview and
alt-tabs.
The original reason for cancelling the pointer grab on compositor grabs
was to avoid a re-entry when a compositor grab was activated while
there was an active pointer constraint grab. The re-entry would happen
when the compositor grab cleared the pointer focus. Clearing the focus
would trigger the pointer constraint to be deactivated, which would end
its grab. Ending the grab would reset the grab to the default one, which
could focus the same surface again, triggering the constraint to
re-enable before it finished disabling.
This is now avoided because the default grab handler is now aware of
compositor grabs, and won't override the cleared pointer focus until
the compositor grab ends.
https://bugzilla.gnome.org/show_bug.cgi?id=772914
Teach the default grab about compositor grabs (i.e.
display->event_route) so that it can avoid setting a pointer focus when
after the compositor grab actively unset the pointer focus.

The frame rect will at this point not be set for Wayland popups, since
the popup is placed and constrained before the actual buffer will be
attached. To still be able to calculate a proper monitor to be used for
constraining, use the ConstraintInfo::current dimensions instead, since
they will have the expected size. This should not cause any issues with
present paths since when a window is otherwise placed, it usually
doesn't change monitor calculation result.
This fixes opening a popup menu that would be positioned on the left
edge of a not-left-most monitor, for example a 'File' menu on a window
maximized on a second monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=773141
Using the view's MetaMonitorInfo to find all the crtcs which should be
configured to display a given onscreen doesn't work unfortunately. The
association runs only the other way around, i.e. we need to go through
each crtc and find the ones corresponding to our monitor info.
https://bugzilla.gnome.org/show_bug.cgi?id=773115
If this isn't initialized and an idle watch gets instanced before
meta_idle_monitor_native_reset_idletime() gets called, that idle watch
would get triggered as soon as we hit the main loop.
This was causing gnome-session to go into idle mode at session start
thus making gnome-shell lock the screen.
In the past this bug was being masked by either logind emiting
session active signals or a stray input event making it through at
startup.

When disabling the device/capability, we can't rely on cancelled events

When the monitor is scaled (i.e. HiDPI scaling) the placement coordinates
ere still in unscaled xdg_surface window geometry coordinate space when

Always use the monitor of the toplevel surface's window, so that the
popup menu and the parent will always have the same scale. This fixes
the dimensions sent in the xdg_popup configure event.
https://bugzilla.gnome.org/show_bug.cgi?id=771841
When Xwayland confines, the surface dimensions will include the server
side window manager decorations. We don't want the decorations to be
included in the constraint region so intersect the calculated input
region with the parts of the buffer rect that is not part of the window
frame.
https://bugzilla.gnome.org/show_bug.cgi?id=771859
Put the conditions for enabling a pointer constraint in a helper
function, and use that in both maybe_enable() and maybe_remove(). The
constraint region checking is still only done in maybe_enable()
however.
This changes the conditions for maybe disabling the constraint on focus
change and other trigger points, namely it makes constraints by Xwayland
not disable when they shouldn't due to the constraining window being an
override-redirect window.
https://bugzilla.gnome.org/show_bug.cgi?id=771859
When the grab is cancelled, for example because of an Alt-tab, VT
switch etc, disable or remove (depending on the constraint type) the
constraint. This avoids a re-entry issue when the focus is returned and
the focus listener tries to re-enable a disabled constraint.
https://bugzilla.gnome.org/show_bug.cgi?id=771859
Dismiss the popup when the grab is cancelled, so that if the grab is
ended for whatever reason (such as VT switching or the last pointer
being disconnected), it doesn't try to end the grab when it isn't
active.
This fixes a crash when VT switching back and forth while a popup grab
is active.
https://bugzilla.gnome.org/show_bug.cgi?id=771858
Previously a grab could suddenly end without the grabber knowing
anything about it. Some grabs assume they won't suddenly end without
notice, and can use then new 'cancel' vfunc to be notified.
Currently a grab is cancelled when a new one is started (i.e. in
meta_wayland_pointer_grab_start()), when a non-popup compositor wide
event route is initiated, and when the seat looses the pointer
capability.
https://bugzilla.gnome.org/show_bug.cgi?id=771858
Instead of using meta_wayland_pointer_end_grab() which focuses the new
grab, add a new helper mean to be used to reset the grab state without
changing the pointer focus. When using this function, the call site is
supposed to explicitly manage focus.
https://bugzilla.gnome.org/show_bug.cgi?id=771646
Make the caller of focus setting check whether there is a pointer to
update the focus state of. It makes it more obvious what to expect, as
the call would be a no-op in when no pointer is present.
Grabbing is still allowed without the presence of a pointer because it
is used by popups even on touch-only systems.
https://bugzilla.gnome.org/show_bug.cgi?id=771646
Make the caller of focus setting and grab starting check whether there
is a keyboard to update the focus state or start grabbing. It makes it
more obvious what to expect, as the call would be a no-op in when no
keyboard is present.

The variable name 'l' usually refers to a GList iterator, but here it's

The order doesn't only affect the visual layout, but also which action
cancels the dialog (and therefore responds to Escape). It is completely

GNOME Shell's window matching currently fails frequently with Flatpak
applications, as one of the primary hints used to link windows with
.desktop files - the WM_CLASS - no longer matches when flatpak renames
the exported .desktop file. Luckily, Flatpak provides us with a fail-safe
way to map from the PID to the corresponding application ID, so expose an
appropriate method that allows GNOME Shell to reliably match windows to
the corresponding Flatpak app.
https://bugzilla.gnome.org/show_bug.cgi?id=772614
In order to kill a window, on both X11 and wayland we first try to
kill(3) the corresponding process, so we can add the newly added
get_client_pid() method to share that code.
https://bugzilla.gnome.org/show_bug.cgi?id=772613
It is often useful to identify the client process that created
a particular window, however the existing meta_window_get_pid()
method relies on _NET_WM_PID, which is only available on X11 and
depends on applications to set it correctly (which may not even
be possible when the app runs in its own PID namespace as Flatpak
apps do). So add a get_client_pid() method that uses windowing
system facilities to resolve the PID associated with a particular
window.
https://bugzilla.gnome.org/show_bug.cgi?id=772613
Previously the focus was reset implicitly by a memset() on the whole
MetaWaylandPointer struct. When MetaWaylandPointer was turned into a
GObject, this was not possible any more, and the focus was not updated
properly.

Going through the global mode pool and then checking if the mode is
available for a given output is pointless work since we can look at
the output's available modes directly.
This implicitly changes how we choose the default mode since, instead
of relying on the sort order of the global modes array, we now rely on
the sort order of the output modes array. Still not ideal, but at
least it makes more sense since the global array is essentially
unsorted.
https://bugzilla.gnome.org/show_bug.cgi?id=772176
This isn't technically needed and, in fact, makes us default to
interlaced modes in some cases which isn't desirable.
Note that X doesn't account for these flags either for its mode

As the m format specifier doesn't consume any arguments, the number
of varargs currently doesn't match the number of specifiers; the
failed transform may be relevant, so include it in the message
instead of removing the excess argument.
There may be other windows managing selection whose events are seen in
our GDK event filter, like st-clipboard in gnome-shell, we should in
that case not interfere on Selection/SelectionRequest events that are
not meant for us.
This fixes an odd feedback loop where requesting clipboard contents from
wayland results in a XConvertRequest call and a SelectionRequest event
that is interpreted by mutter as a request from another X11 client, so
the current data source is poked for content, which happens to be the
X11 bridge, which does a XConvertRequest to get contents... This is only
broken after the many nested async operations create enough pipes and
cancellables to run out of fds.
Adding checks to ensure only events meant to our "selection owner"
window are managed prevent this unintended loop to happen in the first
place.

A xdg_popup, when active, always has a parent surface. However, a popup
created may immediately become invalid, for example when it is not
granted a grab, in which case it won't be assigned a parent since it
will never be mapped.
This case needs to be handled elsewhere, as one cannot assume a
MetaWaylandXdgPoup that is processed (via wl_surface commit handling
etc) will have a parent_surface.
https://bugzilla.gnome.org/show_bug.cgi?id=771495
If a X11 client would initiate a Xdnd session after it had lost pointer
focus (for example when the Xdnd event starting the drag happens after
the implicit pointer grab is already broken due to the button being
released), just end the drag operation instead of dereferencing the
non-existing focus surface.
Also avoid using a native Wayland surface as a drag origin, as that can
never happen, but allow any arbitrary Xwayland client, since there is
no way to find out the actual drag origin.
https://bugzilla.gnome.org/show_bug.cgi?id=770940
We cannot check 'has-target' or 'has-seat' when verifying a
wl_data_offer.finish request is valid or not, since the source may have
effected 'has-target' or whether theh source has a seat or not when the
finish request was already on the wire.
Instead of checking against the source state, keep track whether the
required operations has been done on the offer in question (i.e.
whether an action has been sent, or a mime type been accepted).
This fixes incorrectly raised error when dragging from gtk+'s testdnd
via Xwayland onto gtk+'s testdnd using Wayland.

Since wl_surface.set_buffer_transform() is not supported, until it is
added, pretend outputs are never transformed, so that clients are less
likely to attach pre-transformed buffers.
https://bugzilla.gnome.org/show_bug.cgi?id=770672
Also maybe remove a constraint when the pointer focus changes. This is
needed because when Xwayland has a constraint focus may change, the
constraint object will not receive a 'appears-focused' event on its
window since it never changed.
This happens for example when an override-redirect window (which never
appears focused) holds the constraint, and alt-tab happens. In this case
focus changes, but from the constraint's point of view, none of the
windows it knows about changed its focus appearance.
https://bugzilla.gnome.org/show_bug.cgi?id=771345
Instead of initializing the default grab when the device class is
enabled, initialize it on object initialization. This way other device
classes can still grab the pointer, as if there was one. This may be
useful for example if a touch grab is active and a mouse is connected.
This also makes it possible for popup grabs, which currently use a
pointer grab for controlling, to be triggered by touch devices, while
still holding an active pointer grab.
https://bugzilla.gnome.org/show_bug.cgi?id=771305
Make the device <-> seat association permanent, and move it into

Some output devices only advertise their preferred mode even though
they're able to display others too. This means we can include some
common modes in each output's supported list.
This is particularly important for mirroring, since we can only mirror
outputs which are using the same resolution.
https://bugzilla.gnome.org/show_bug.cgi?id=744544
Since Xwayland surface constraints might need to enable not only
because the constrained window appears focused, add a pointer focus
listener and try constrain whenever the pointer focus changes. It's
still required that a Xwayland window is focused to activate.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
Xwayland surfaces are special, because there is no reliable way to
associate a window with its corresponding "application window" (the one
which was given focus). Many games that require pointer warping and
confining pointer grabs may for example create override redirect windows
and make that window receive input even though it will never be the
focus window.
Therefore, the requirements for enabling a constraint for a wl_surface
from Xwayland needs to be relaxed in order. This commit changes
Xwayland wl_surfaces to not require being focused to be enabled; it'll
be enabled as long as any X11 window is the one with focus.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
Require pointer focus to enable, otherwise we can't guarantee it has

Add a signal that is emitted when the pointer focus surface of the

For Xwayland, a newly created wl_surface and X11 Window pair may not be

has been associated.

If a client would attach a buffer to a surface, commit, destroy the
buffer and then later set the surface as a cursor, there will be no
wl_buffer available to be used by the cursor role. Instead of
dereferencing the non-existing wl_buffer resource, handle this situation
by logging a warning and treating a prematurely destroyd wl_buffer as if
no buffer had been attached.
https://bugzilla.gnome.org/show_bug.cgi?id=770992
Not having a surface actor would cause the window actor state to be
considered frozen, thus causing various state (such as geometry, shape
etc) synchronization to be delayed until thawed. If the window actor
was "thawed" due to having a surface set, not all state would be
properly synchronized, causing the thawed window actor to be displayed
incorrectly.
This patch fixes this by putting state synchronization after thawing in
a common function, calling it both from frozen count decreasing and
surface setting.
This fixes for example misplaced menus in Steam.

The seat capability updating is synchronous, but input events are
asynchronous (first queued then emitted). This means we may end up in a
situation where we from libinput first may receive a key event,
immediately followed by a device-removed event. Clutter will first
queue the key event, then remove the device, immediately triggering the
seat capability removal.
Later, when the clutter stage processes the queued events, the
previously queued key event will be processed, eventually making it
into MetaWaylandSeat. Before this patch, MetaWaylandSeat would still
forward the key event to MetaWaylandKeyboard, even though it had
'released' it. Doing this would cause referencing potentially freed
memory, such as the xkb state that was unreferenced when the seat
removed the capability.
In order to avoid processing these lingering events, for now, just drop
them on the floor if the capability has been removed.
Eventually, the event queuing etc needs to be redesigned to work better
when used in a Wayland compositor, but for now at least don't access
freed memory.
https://bugzilla.gnome.org/show_bug.cgi?id=770727
When a modal transient is unmanaging, most likely the parent of the
modal transient should be focused.
In Wayland, a MetaWindow is created when a shell surface role (like
xdg_toplevel) is created, but a window cannot be shown until a buffer
is attached. If a client would create two modal transients and make
them both have the same parent, but only one get a buffer attached
(i.e. shown), when unmanaging the modal transient that was showing,
when finding a new focus candidate, the stacking code will ignore the
not-to-be-shown buffer-less modal transient when finding a good
candidate for focusing. In the case described here, this means it will
find the parent of the unmanaging modal transient.
This newly chosen candidate will then be passed to meta_window_focus();
meta_window_focus() will then try to find any modal transient to focus
instead, will find the one without any buffer, then fail to focus it
because it cannot be mapped, thus making meta_window_focus() not focus
anything. Since meta_window_focus() didn't change any focus state, the
assert in meta_window_unmanage() checking that the unmanaging window
isn't focused anymore will be hit, causing mutter to abort.
For now, fix this by checking whether the modal transient can actually
be focused in meta_window_focus(). For X11 client windows, a window
will be defined to be focusable always, but for Wayland client windows,
a window will be determined focusable only if it has a buffer attached.
In the future, we should probably do a more thorough refactorization of
focus handling to get rid of any X11 - Wayland differences.

We may be assigned multiple times, if the surface is assigned to be a
cursor surface multiple times. Each time e.g. wl_pointer.set_cursor is
called, we'll be assigned.
While the role object exists, we'll handle buffer use count even when
we are not actively assigned, thus we should only handle the initial
assignment use count bump when constructing, so that we don't increase
it when reassigned, where the wl_resource may already have been
released.

For backend handled cursors, if nothing else changes on the clutter
stage, we end up not sending out frame callbacks since clutter doesn't
draw a new frame.
To fix this, we'll keep cursor surfaces' frame callbacks separate from
other surfaces' and trigger them from the new
MetaCursorRenderer::cursor-painted signal which handles both software
and hardware cursors.
https://bugzilla.gnome.org/show_bug.cgi?id=749913
This signal allows interested parties to be notified of a new cursor
frame being painted regardless of whether it's being painted by the
backend directly or if it's a software rendered cursor frame handled
by clutter.

Even without a compositor grab, key events may still be expected to
be processed by the compositor and not applications, for instance
when using ctrl-alt-tab to keynav in the top bar. On X11, focus is
moved to the stage window in that case, so that events are processed
before they are dispatched by the window manager. On wayland, we need
to handle this case ourselves, so make sure to not pass key events to
wayland in that case, and move the key focus back to the stage when
appropriate.

Switch to the output naming logic used by the X server's modesetting

If cogl fails to create a texture from the client's given buffer,
mutter would raise a fatal error and terminate.
As a result, a broken client might kill gnome-shell/mutter and take the
entire Wayland session with it.
Instead of raising a fatal error in this case, log the cogl error
message and send the client an OOM error, so mutter/gnome-shell can
survive an unsupported buffer size.

For some reason, when a modal dialog was made an attaching
transient-for, if the window wasn't "constructing", it would be
unmanaged and rely on some side effect to be recreated. This side
effect is not triggered for Wayland clients, thus if one happen to set
a surface as "modal" via gtk_surface.set_modal before
xdg_toplevel.set_parent, it'd be unmanaged and never show up.
Instead, simply just set the tranciency anyway for Wayland clients.
This makes GTK+ clients that set_modal() before set_transient_for()
work.
