When cleaning up the display name string management, the display name
string retrieved from libwayland-server was also passed to free() on

The 'data' object is attached to the MetaWaylandSurface as a GObject

Since a wl_buffer is independent of the GL context in use (unlike, e.g.,
a GL renderbuffer), EGLImages with the EGL_WAYLAND_BUFFER_WL target must
pass EGL_NO_CONTEXT as the context. Quoting from the

After querying the wl_buffer layout, create EGLImages for the

EGLClientBuffer, EGL_WAYLAND_BUFFER_WL as the target, NULL

Ideally we would accumulate the angle and report a wheel event with an
appropriate value for "clicks". We can get away with a much cruder method
for the time being, however, since no Wacom tablet puck actually provides
a smooth scrollwheel. Checking whether the angle in CLUTTER_INPUT_AXIS_WHEEL

When updating the main monitor, make sure to update the toplevel main
monitor before trying to use that as the main monitor for non-toplevel
windows (such as popups). Without this, when the main monitor is
updated as a side effect to monitors being changed (for example due to
a hot plug event, or coming back from being suspended) the
main monitor pointer may, after 'monitors-changed' has completed, point to
freed memory resulting in undefined behaviour.

To be able to render the pointer cursor sprite at sub-(logical)-pixel

When the logical layout mode is used, allow configuring the scaling to
be non-integer. Supported scales are so far hard coded to include at

Wayland outputs are set to have scale ceil(actual_scale) meaning well

Window moving and resizing depends on the `meta_wayland_seat_get_grab_info`

Previously, the function only returned `TRUE` if the given surface was

Use the "destroy" MetaWaylandSurface signal instead of the wl_resource
destroy signal for tracking the lifetime of the surface with pointer

As unsetting the focus may have side effects due to handlers of the

If a client changes the state of a surface to issue a set_maximize, this
causes apply_pending_state() to be called before mutter has placed the
window.
If the monitor on which the window is to be shown initially is different
from the one where the pointer is placed, this causes the effect to be
played at the wrong location before the window eventually reaches its
location on another monitor.
Force the window to be placed prior to change its state to maximized in
xdg-shell so that mutter won't relocate the window afterwards.
This also avoids sending an xdg_toplevel.configure with a size of 0x0
which would cause the client to initially draw its surface with some
arbitrary size.

If the client doesn't set a geometry using xdg_shell, we'll compute its
geometry based on its surface and subsurfaces.
Yet, we translate that as a window (re)size only when there is a pending

This commit adds support for rendering onto enlarged per logical
monitor framebuffers, using the scaled clutter stage views, for HiDPI
enabled logical monitors.
This works by scaling the mode of the monitors in a logical monitors by
the scale, no longer relying on scaling the window actors and window
geometry for making windows have the correct size on HiDPI monitors.
It is disabled by default, as in automatically created configurations
will still use the old mode. This is partly because Xwayland clients
will not yet work good enough to make it feasible.
To enable, add the 'scale-monitor-framebuffer' keyword to the
org.gnome.mutter.experimental-features gsettings array.
It is still possible to specify the mode via the new D-Bus API, which
has been adapted.
The adaptations to the D-Bus API means the caller need to be aware of
how to position logical monitors on the stage grid. This depends on the
'layout-mode' property that is used (see the DisplayConfig D-Bus
documentation).

We are keeping accounting of the focus window as seen by the DnD bridge
right here, so use it instead of the MetaWaylandDragGrab focus as it may
lag behind the real focus (i.e. till the drag source notices the window
and sends XdndEnter to it).
This leads to the window trying to be repositioned more often than
necessary when the drag source takes long to send the XdndEnter client
message, and maybe not repositioned at all if the pointer leaves the
surface while no XdndEnter message was received.
https://bugzilla.gnome.org/show_bug.cgi?id=763246
We currently wait for the selection being cleared by the drag source,
which might not happen on not quite educated clients. This may leave
a stuck XDND grab in the compositor side.
We can actually do a bit better, and clear the grab if:
1) The drag source sent XdndDrop to the wayland drag destination.
2) There's no accepting drag destination and all pointer buttons are
released.
3) As usual, whenever the drag source clears the selection data

No XDnD events which notify DnD status change comes in Wayland. To emulate XDnD

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

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.

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.

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.

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

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

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

Always use the monitor of the toplevel surface's window, so that the

When Xwayland confines, the surface dimensions will include the server

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

When the grab is cancelled, for example because of an Alt-tab, VT

Dismiss the popup when the grab is cancelled, so that if the grab is

is active.

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

In order to kill a window, on both X11 and wayland we first try to

It is often useful to identify the client process that created

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

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

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.

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.

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.

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.

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.

Make the device <-> seat association permanent, and move it into
MetaWaylandInputDevice. A device will never be disassociated with a
seat, so there is no point in unsetting it.
https://bugzilla.gnome.org/show_bug.cgi?id=771305
Add a new object class, MetaWaylandInputDevice, and make all device
classes (pointer, keyboard, touch) inherit it. In the future common
functionality may be placed there.

Meant to replace explicitly checking whether a
MetaWaylandPointer/MetaWaylandKeyboard/MetaWaylandTouch has a seat or
not to determine whether they are supposed to be active or not.

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
entered the surface, as the focus may have been given to a subsurface,
override-redirect or other sub window covering the surface that was
requested to have o pointer constraint.

Add a signal that is emitted when the pointer focus surface of the
pointer device changes. This will later be used by the pointer
constraints to maybe enable pointer constraints when a surface receives
pointer focus.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
For Xwayland, a newly created wl_surface and X11 Window pair may not be
immediately associated, but Xwayland may still request a pointer
constraint on some of its wl_surface's. Handle the situation by
postponing maybe enabling the constraint until the window and surface
has been associated.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
Move the MetaWaylandSurface::destroy signal before starting the actual
destruction, in wl_surface_destructor, so that all fields (e.g. surface
role) are intact when the listeners are invoked.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
When the Xwayland wl_surface is created, it may not yet be possible to
associate it with the corresponding X11 Window. Add a signal to the
Xwayland role to communicate with any interested parties.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
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.

Implement min/max size request from xdg-shell-v6 and plug it into the
existing code so that windows with fixed size cannot be tiled/maximized
in Wayland just like in X11.

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.
