All pads will share the same focus than the keyboard, so this means that:
- The focus changes in-sync for keyboard and all pad devices, and
- Newly plugged pads will be immediately focused on that same surface
This object represents the collection of buttons, strips and rings
in a tablet pad. All the objects created (pad, strips and rings)
share a common focus surface and have the same lifetime.
This is now separated from the generic cursor one. This means that wl_surfaces
can't be shared across wl_pointer and wp_tablet_tool. This is a change in
tablet protocol v2.
This is a simple subclass of MetaWaylandSurfaceRoleCursor, mostly
so we can distinguish by GType, the methods in the parent class
still apply and are useful.
Using clutter API to transform coordinates is only accurate right
after a clutter layout pass but this function is used e.g. to deliver
pointer motion events which can happen at any time. This isn't a
problem for wayland clients since they don't control their position,
but X clients do and we'd be sending outdated coordinates if a client
is moving a window in response to motion events.

The call fetching the targets mistakenly used the timestamp meant
to back up the TIMESTAMP atom (hence, it's the timestamp at which
the selection is *owned* by the compositor, on behalf of a wayland
client).
This timestamp is actually only updated when the compositor gets
to own the selection, so it's a randomly late timestamp to retrieve
the TARGETS atom content, which certain clients might end up
ignoring.

The result flag needs to be marked as moved even for pending moves,
otherwise the window's unconstrained_rect doesn't get updated in
meta_window_move_resize_internal() and the anchor grab is wrong.

The X11 backend uses EWMH's _NET_WM_PID to get the PID of an offending
client and kill its PID to force the client to terminate.
The Wayland backend is using a Wayland protocol error, but if the client
is hung, that will not be sufficient to kill the client.
Retrieve the client PID under Wayland using the Wayland client API
wl_client_get_credentials() and kill() the client the same way the X11
backend does.

xdg-shell allows desktop environments to extend the list of states
within a given range.
Use this possibility to add a new state for tiled so that gtk+ can

This makes us behave the same both on bind and when an output
changes. In particular, we were not sending scale and done events on
output changes. We were also unconditionally sending mode events on
output changes even though these should only be sent if there is an
actual mode change.
https://bugzilla.gnome.org/show_bug.cgi?id=766528
If we try to send notify event (either from surface_state_changed()
or from meta_window_wayland_move_resize_internal()),
we will crash, because we don't have a sufrace anymore.
There's no reason why to resize the window that is being
unmanaged anyway.

meta_wayland_tablet_manager_update()/handle_event() are called before
the MetaWaylandSeat counterparts. If the event comes from a device
managed by MetaWaylandTabletManager, the event will be exclusively handled
by it.
Each tool has its own MetaCursorRenderer instance, which is created/destroyed
upon proximity, and possibly updated through focus and set_cursor calls in
between.
This struct keeps the server side information for the wl_tablet_manager
global resource. It keeps the clients requesting this interface, and
does keep track of the plugged tablet devices, so
wl_tablet_manager.device_added is emitted on the expected clients.
Move into a standalone meta-wayland-surface-role-cursor.[ch], and
make generic enough to work for pointe and additional (eg. tablet)
cursors.
Most notably, the sprite is now kept completely internal to the
cursor role, and updates are routed through the given
MetaCursorRenderer (which may be the default one for the pointer,
or something else).
The way cursor updates after cursor surface destruction has also
been reworked, the pointer will just keep track of the last cursor
surface, so older surfaces being destroyed don't trigger pointer
rechecks/updates.
There's places where it would be convenient to add listeners to this,
so add the signal. The signal is only emitted once during destruction,
it is convenient for the places where we want notifications at a time
the object is still alive, as opposed to weak refs which notify after
the fact.
Separate "xdg_surface", "xdg_popup" and "xdg_shell" related functions
into three sections. Prior to this, the "xdg_shell" part was a bit all
over the place.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Dismiss the popup when the parent is destroyed, and do this in the
destructor of the parent object. This makes the parent destory listener
unnecessary, since we already handle the parent child unlinking
explicitly in the object destructor.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Instead of relying on destroy signals attached to the corresponding
role object, let the roles explicitly dismiss the popup when it should
be dismissed.

Add a bridge between the MetaWaylandPopup object and the corresponding

Before this commit, on Wayland, the buffer rect would have the size of
the attached Wayland buffer, no matter the scale. The scale would then
be applied ad-hoc by callers when a sane rectangle was needed. This
commit changes buffer_rect to rather represent the surface rect (i.e.
what is drawn on the stage, including client side shadow). The users of
buffer_rect will no longer need to scale the buffer_rect themself to
get a usable rectangle.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
A large part of meta_wayland_surface_apply_window_state() was only
relevant for xdg_surface. Make this more obvious by splitting it up,
moving the relevant parts to the relevant roles.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Move xdg_shell related functionality to a new meta-wayland-xdg-shell.c
and wl_shell related functionality to a new meta-wayland-wl-shell.c,
and adapt role object tree.
Common functionality related to the surface being drawn as a
MetaSurfaceActor was moved to a MetaWaylandSurfaceRoleActorSurface role.
The subsurface role GObject is made to inherit the actor surface GObject.
Shell surface hooks (configure, ping, close, popup done) were added to
a MetaWaylandSurfaceRoleShellSurface GObject which inherits the
surface actor role GObject.
The shell surface roles (xdg_surface, xdg_popup, wl_shell_surface) are
made to inherit the shell surface GObject and implement the relevant
API.

Leave these checks up to the callers, the only uses of this function
(indirect, through meta_wayland_seat_get_grab_info) are
[wl_shell|xdg]_surface.move/resize/show_window_menu.
In move/resize it makes sense to check for a button being pressed, because
we must expect a button release event. However for xdg_surface.show_window_menu
we 1) don't strictly need further events and 2) we must account for press+release
event pairs being processed at once in the compositor before the client sees
the former.
That is eg. the case of touchpad 2nd/3rd button tap emulation, multifinger
taps will emit the event pair at once, so when the client manages to request
xdg_surface.show_window_menu, it'll be too late in the compositor side, so the
request is ignored.
https://bugzilla.gnome.org/show_bug.cgi?id=764519
A wl_data_device object may be created while it is being focused,
either because the client destroyed it or because the client was
destroyed. Handle this by early out in focus handler vfuncs the case
where it was destroyed, so that we don't corrupt memory and/or cause
segmentation fault.
https://bugzilla.gnome.org/show_bug.cgi?id=765062
If we get a key event but still have pending modifier state changes we
need to send a modifiers event right away so that the key event can be
interpreted by clients correctly modified.
This case could happen when mutter/gnome-shell itself consumes the
modifier key press event such as with the overview key which by
default is triggered on super press.
https://bugzilla.gnome.org/show_bug.cgi?id=748526
The wayland protocol has enough space to send both virtual and real
modifiers on modifiers events which saves clients the work of
resolving virtual modifiers themselves.
https://bugzilla.gnome.org/show_bug.cgi?id=748526
While CoglError is a define to GError, it doesn't follow the convention
of ignoring errors when NULL is passed, but rather treats the error as
fatal :-(
That's clearly unwanted for a compositor, so make sure to always pass
an error parameter where a runtime error is possible (i.e. any CoglError
that is not a malformed blend string).
https://bugzilla.gnome.org/show_bug.cgi?id=765058
Just like we do for _NET_WM_MOVERESIZE messages on X11, consider
wayland client move/resizes as "frame actions" so that the same
constraints are applied to them, in particular the titlebar visibility
constraint.
https://bugzilla.gnome.org/show_bug.cgi?id=748819
In order for the native cursor renderer to be able to create a hw
cursor in response to wl_pointer.set_cursor(), keep a private use-count
and reference to the active buffer, stopping it from being released
until it is consumed, replaced, or the surface is destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=762828
Whether a surface needs to keep the committed wl_buffer un-released
depends on what role the surface gets assigned to. For example a cursor
role may need an unreleased shm buffer in order to create a hw cursor from
it.
In order to support this, keep a separate reference and use count to
the buffer on behalf of the in the future assigned role, and release
those references after the surface was assigned a role. A role that
needs its own references and use counts, must in its assign function
make sure to add those.
https://bugzilla.gnome.org/show_bug.cgi?id=762828
Each wl_surface.commit with a newly attached buffer should result in
one wl_buffer.release for the attached buffer. For example attaching
the same buffer to two different surfaces must always result in two
wl_buffer.release events being emitted by the server. The client is
responsible for counting the wl_buffer.release events and be sure to
have received as many release events as it has attached and committed
the buffer, before reusing it.
https://bugzilla.gnome.org/show_bug.cgi?id=762828
This target is set whenever DnD moves towards an area between surfaces.
Although no offer is set and data is actually not read, drag sources
offering this mimetype will be able to behave just like they used to
do in X11.
https://bugzilla.gnome.org/show_bug.cgi?id=762104
We want some initial processing, even if the current focus didn't change.
This could be for example the case of starting DnD too close to the window
edge and out of it. At the point start_drag() is called, the current
pointer focus is already NULL, so set_focus() would simply bail out here.
https://bugzilla.gnome.org/show_bug.cgi?id=762104
On the X11 backend we don't track the pointer position in
priv->current_x/y which remain set to zero. That means we never set
the clutter stage cursor if point 0,0 isn't covered by any monitor
since we return early.
Commit 4bebc5e5fa introduced this to
avoid crashing on the prepare-at handlers when the cursor position
doesn't fall inside any monitor area but we can handle that higher up
in the stack. In that case, the sprite's scale doesn't matter since
the cursor won't be shown anyway so we can skip setting it.
https://bugzilla.gnome.org/show_bug.cgi?id=763159
This commits adds a gtk_surface.present request and its implementation.
The timestamp is assumed to be from some input event that the client
responded to. The timestamps we deal with when managing windows will
usually come from two different clocks: CLOCK_MONOTONIC if they come
from libinput/evdev, or CLOCK_MONOTONIC_COARSE if they come from the
X server.
Luckily these are quite similar, the difference beeing that the X server
timestamps having lower resolution, so we can just pass the timestamps
no matter where they came from and it'll most likely work fine, except
for the race condition described in bug 756272 which might happen here
too until it is properly fixed.
https://bugzilla.gnome.org/show_bug.cgi?id=763295

The gtk_shell protocol used some half baked unstable protocol semantics
that worked by only allowing binding the exact version of the
interface. This hack is a bit too confusing and it makes it impossible
to do any compatible changes without breaking things.
So, instead rename it to include a number in the interface names. This
way we can add requests and events without causing compatibility issues,
and we can later remove requests and events by bumping the number in
the interface names.

Using the current position to set the origin x/y of the DnD icon
is wrong, it should still be used in order to move the icon besides
the current pointer position though.
Fixes possible drag-start-x/y property constraint warnings when
starting a drag too close to the window edge, and towards outside
of it.
If a MetaWindow's 'appears-focused' state changed to true, but the
window did not have pointer focus, the constraint did not enable. Thus,
make it possible for the user to also click the window to enable it.
https://bugzilla.gnome.org/show_bug.cgi?id=762661
Instead of relying on the keyboard focus surface, use the
'appears-focused' state of the corresponding MetaWindow to determine if
a constraint should enable or not.

Instead of having MetaWindowWayland having hooks into pointer

Instead of having a very large region represent an infinitely large

MetaWaylandSurface if the constraint region was not set.
https://bugzilla.gnome.org/show_bug.cgi?id=762661
The when surface->input_region is NULL, it should be interpreted as the
whole surface region. If not, the effective input region is the
intersection of the buffer region and the input region set by
wl_surface.set_input_region. Add
meta_wayland_surface_calculate_input_region() that does this
calculation.

If we receive multiple SelectionRequest events, we'll end up replacing the
former WaylandSelectionData at a time when an async read has been issued.
This will cause the cancellation of the previous operation.
But the wayland_data_read() callback will attempt to just remove the
current wayland data again on error, which will not be the one we're
cancelling, so the new operation will just be cancelled too.
Also, cancellation is no longer warned about. As the wayland selection
has been replaced at this time, we can just return here.

We may have released the wl_buffer already when doing this, which means
we should not try to access the wl_buffer content.
Regarding the cursor texture this is not an issue since we can just use
the texture created in apply_pending_state().
The hw cursor however will only be realized if the surface is already
using the the buffer (surface->using_buffer == true). This will, at the
moment, effectively disable hardware cursors for SHM buffers.
https://bugzilla.gnome.org/show_bug.cgi?id=762828
Don't unset the surface->buffer if the associated wl_buffer object is
destroyed. The MetaWaylandBuffer doesn't really only represent a
wl_buffer object, but also the data (texture) created from the given
wl_buffer. Thus, for example destroying a released SHM wl_buffer should
not destroy the MetaWaylandBuffer instance, because the texture may
still be used.
This commit also fixes a race where calc_showing would hide a window
because, at the time of calculation whether it should be showing, the
surface's buffer had been destroyed as described above.
https://bugzilla.gnome.org/show_bug.cgi?id=762716
In destroy_data_offer() there is code to ensure compatibility when
dragging from a v3 wl_data_device to a v2 one, it's however not checking
correctly that this is the DnD drag source. The other path should be
used otherwise.

Add an additional MetaWaylandDataSource implementation for primary selection
sources, and methods to set primary selection offers. Primary selection
sets altogether a different channel than the clipboard selection, those don't
cross in any way.
Also, the bridge for the X11 PRIMARY selection atom has been added, which
adds all the necessary handling to translate primary selection both ways
with wayland and X11 applications.
https://bugzilla.gnome.org/show_bug.cgi?id=762560
This protocol is an internal mirror of the primary selection drafts
being proposed for wayland-protocols. No changes besides prefix/suffix
changes.
https://bugzilla.gnome.org/show_bug.cgi?id=762560
The constraint may be destroyed before the client destroyes the
protocol object, for example if a oneshot constraint was disabled by
alt-tab. Therefore we need to NULL check the constraint in request
handlers and ignore any requests to defunct objects.
Add a gtk_shell.set_startup_id request, so the application can communicate
to the compositor the startup id that it received through the

Since a buffer can be used by multiple surfaces at once,
we need to release the buffer only after all surfaces
are finished with it. Currently we track whether or
not to release the buffer based on the accessible boolean.
This commit changes it to a counter to accomodate multiple
users.
Also, each surface needs to know whether not it is done with
the buffer, so this commit adds a buffer_used boolean to the
surface state.
https://bugzilla.gnome.org/show_bug.cgi?id=761613
We currently track whether or not a buffer can be released early
by looking at the copied_data boolean on the buffer. This boolean
is, practically speaking, always set to TRUE for shm buffers and is
always false otherwise.
We can just as easily check if the buffer is a shm buffer to decide
whether or not to do an early release. That's better from a
theoretical point of view since copied_data assumes a 1-to-1
relationship between surface and buffer, which may not actually hold.
This commit drops copied_data and changes the check to instead see
if the buffer is shm.
https://bugzilla.gnome.org/show_bug.cgi?id=761613
meta_wayland_surface_toplevel_commit has a lot of logic to handle

The wp_pointer_constraints protocol is a protocol which enables clients
to manipulate the behavior of the pointer cursor associated with a seat.
Currently available constraints are locking the pointer to a static
position, and confining the pointer to a given region.
Currently locking is fully implemented, and confining is implemented for
rectangular confinement regions.
What else is lacking is less troublesome semantics for enabling the lock
or confinement; currently the only requirement implemented is that the
window that appears focused is the one that may aquire the lock.
This means that a pointer could be 'stolen' by creating a new window that
receives active focus, or when using focus-follows-mouse, a pointer
passes a window that has requested a lock. This semantics can be changed
and the protocol itself allows any semantics as seems fit.
https://bugzilla.gnome.org/show_bug.cgi?id=744104
Add support for sending relative pointer motion deltas to clients who

The code currently implements a function, get_time, that

commit 0165cb6974 changed
mutter to release committed shm buffers as soon as they were
uploaded to the GPU.

https://bugzilla.gnome.org/show_bug.cgi?id=761312
When a client is ready for the compositor to read a surface's
shared memory buffer, it tells the compositor via
wl_surface_commit.
From that point forward, the baton is given to the compositor:
it knows it can read the buffer without worring about the client
making changes out from under it.
After the compositor has uploaded the pixel contents to the video
card it is supposed to release the buffer back to the client so that
the client can reuse it for future use.
At the moment, mutter only releases the buffer when a new buffer
is attached. This is problematic, since it means the client has
to have a second buffer prepared before the compositor gives the
first one back. Preparing the second buffer potentially involves
copying megabytes of pixel data, so that's suboptimal, and there's
no reason mutter couldn't release the buffer earlier.
This commit changes mutter to release a surface's buffer as soon
as it's done processing the commit request.
https://bugzilla.gnome.org/show_bug.cgi?id=761312
Since we are using the surface actor to draw the DND icon, the offset
is already accounted for by MetaSurfaceActorWayland, and passing the
surface position offset would effectively double the actual offset,
causing the icon to be misplaced.
This patch always sets the anchor offset to (0, 0) when the icon is a
Wayland surface, and lets the surface actor deal with the offsetting.
https://bugzilla.gnome.org/show_bug.cgi?id=759222
We now additionally send:
- wl_data_offer.source_actions
- wl_data_source.action
- wl_data_offer.action
- wl_data_source.dnd_drop_performed
- wl_data_source.dnd_finished
The protocol changes allow for compositors to implement different policies
when chosing the action, mutter uses this to reimplement the same behavior
that GTK+ traditionally had:
- Alt/Control/Shift modifiers change the chosen action to
ask/copy/move respectively
- Drags with middle button start out as "ask" by default
As mutter now also grabs the keyboard and unsets the window focus for these
purposes, the window focus is restored after the drag operation has
finished.
The Xdnd bridge code is also modified to cope with actions, so mixed
wayland-x11 scenarios are able to convey that information.
https://bugzilla.gnome.org/show_bug.cgi?id=760805
This will be useful during DnD, where mutter is expected to consume
keyboard events for either allowing changes in the selected DnD action,
or misc a11y features like keyboard-driven DnD.
Currently, the vtable contains 2 functions, key() will be used on every
key event we get from Clutter, modifiers() will notify of changes in the
keyboard modifiers (mouse buttons will never be set in the modifier mask)

As per the spec:
- wl_pointer.axis_source determines the current source of
scroll events.
- wl_pointer.axis_stop determines when there's no further
scroll events on the given axis.
- wl_pointer.axis_discrete is emitted on "wheel"
scroll sources, measured in ticks.
- wl_pointer.frame is meant to coalesce events that logically belong
together, e.g. axis events in this case.

During xwayland initialization we run main loop and dispatch wayland
events, so that xwayland can initialize. If some client during this
phase connects and creates surface, mutter crashes because
it is not initialized yet. If we bind wayland socket after xwayland

connect to mutter during initialization and that is what we want.

Use the xdg_shell XML file installed by wayland-protocols instead of
our own copy. This protocol has yet to go through any unstable naming,
but since we had an outdated (though wire compatible) version, some
minor changes were needed.
https://bugzilla.gnome.org/show_bug.cgi?id=758633
Remove our own copy of the pointer gestures protocol, and us the one
installed by wayland-protocols. This also means the new fixed unstable

a rename.

When running as a native compositor, we can just do that. However, the
previous code must stay for whenever it's run as a X11 client.
Additionally, the fallback switch{} that transforms clutter 1-indexed
buttons into input.h event codes had to be adapted to the change introduced
in clutter commit 83b738c0e, where the 4-7 button range is kept clear for
compatibility with the X11 backend.

On the wire, Wayland specifies the refresh rate in milliHz. Mutter sends
the refresh rate in Hz, which confuses clients, e.g. weston-info:
interface: 'wl_output', version: 2, name: 4
mode:
width: 2560 px, height: 1440 px, refresh: 0 Hz,
flags: current preferred
interface: 'wl_output', version: 2, name: 5
mode:
width: 3200 px, height: 1800 px, refresh: 0 Hz,
flags: current preferred
and xrandr:
XWAYLAND0 connected 2560x1440+3200+0 600mm x 340mm
2560x1440@0.1Hz 0.05*+
XWAYLAND1 connected 3200x1800+0+0 290mm x 170mm
3200x1800@0.1Hz 0.03*+
Export the refresh rate in the correct units. For improved precision,
perform the KMS intermediate calculations in milliHz as well, and
account for interlaced/doublescan modes.
This is also consistent with what GTK+ expects:
timings->refresh_interval = 16667; /* default to 1/60th of a second */
/* We pick a random output out of the outputs that the window touches
* The rate here is in milli-hertz */
int refresh_rate = _gdk_wayland_screen_get_output_refresh_rate (wayland_display->screen,
impl->outputs->data);
if (refresh_rate != 0)
timings->refresh_interval = G_GINT64_CONSTANT(1000000000) / refresh_rate;
Where the 'refresh_rate' given is exactly what's come off the wire.
1000000000/60000 comes out as 16667, whereas divided by 60 is ...
substantially less.

Right now we just check the pointer serial, so the popup will be
immediately dismissed if the client passes a serial corresponding to
another input device.
Abstract this a bit further and add a meta_wayland_seat_can_popup() call
that will check the serial all input devices. This makes it possible to
trigger menus through touch or keyboard devices.

If we immediately dismiss the popup, we still need to set the
surface->xdg_popup pointer field in order for the destructor to
properly clean up the state. Not doing this may cause a crash if the
xdg_popup resource that was immediately dismissed is destoryed after
wl_surface during client destruction.

We don't have any way of knowing what the intended size of a XWayland
cursor is supposed to be, so lets do what we do with regular XWayland
surfaces and don't scale them. The result is that cursor sprites of
HiDPI aware X11 clients will show correctly, but non-aware clients may
have tiny cursor sprites.

Each keyboard focus change ends up calling the MetaWaylandDataDevice
counterpart, we don't need though to notify the current selection
again. In order to fix this, keep track of the current client, and
only emit the relevant signals when the focus switches to another
client.
The situations where wl_data_device.selection were emitted during
focus changes between surfaces of the same client was inocuous most
of the times, although it's prone to inducing confusing behavior
on context menu clipboard actions, as the closing menu triggers a
focus change, which triggers a whole new wl_data_offer being created
and given on wl_data_device.selection, at a time where there's already
ongoing requests on the previous data offer.

If the transfer is cancelled, the X11SelectionData will be cleared from
the MetaSelectionBridge, although x11_data_write_cb() was invariably
expecting it to be non-NULL.
If the write was cancelled, all the actions done in x11_data_write_cb()
are moot, so just return early. If there's other errors happening
(eg. "connection closed" if the target client happens to crash), we
should still attempt at clearing the data anyway.
