This fixes an issue analogous to bug 760330 for the X11 backend,
except on this backend we wouldn't crash accessing free'd memory.
Instead we're leaking watches since we steal them from the hash table
which means that when they're removed in
_meta_idle_monitor_watch_fire() they're no longer there and thus
they're never free'd.
https://bugzilla.gnome.org/show_bug.cgi?id=760476
Right now the XSync based idle monitoring code, will fetch all active
watches into a list, and then call their watch callbacks one by one
as necessary. If one watch callback invalidates another watch, the
list will contain free'd memory.
This commit makes sure to consult the hash table after ever call
of a watch callback, to ensure mutter never looks at freed memory.
Fixes crash reported on IRC by Laine Stump with his synergy setup.

The new tiling code, instead of based around "tiling states", is instead
based around constrained edges. This allows us to have windows that have
three constrained edges, but keep one free-floating, e.g. a window tiled
to the left has the left, top, and bottom edges constrained, but the
right edge can be left resizable.
This system also is easily extended to support corner tiling. We also,
using the new "size state" system, also keep normal, tiled, and
maximized sizes independently, allowing the maximize button to bounce
between maximized and tiled states without reverting to normal in
between. Dragging from the top will always restore the normal state,
though.

We can know the rotation modes supported by the driver, so
export these as our supported modes, and ensure these modes
are honored on the CRTC primary plane upon apply_configuration().
It is worth noting however that not all hardware will be
capable of supporting all rotation modes (in fact, most of
them won't). A driver independent solution should be in
place to back up the rotation modes unsupported by the
drivers, so this is still a partial solution.
The cursor renderer has also been changed to default to
software-based rendering anytime the cursor enters a
rotated CRTC. Another solution would be actually rotating
the DRM cursor planes, but then it requires applying rotation on
these per-CRTC, and actually transforming the pointer position by
the output matrix. This brings marginal gains, so we use the
"sw" rendered cursor, which will be transformed together with
the primary plane.

In case a window is hidden when we're ordered to make it transient to
a different parent we must re-evaluate its visibility status or we'll

This seems like a more generally useful and intuitive behavior. Note
that, in X sessions, this is what already happened in practice since
meta_display_begin_grab_op() calls meta_window_grab_all_keys() which,
on X11, does meta_window_focus().

This is a really old behavior introduced in commit

it only applies to SSD windows.

it applies consistently to all windows.

Some applications, like Chromium, explicitly set their bounding region
to the client area when full-screen. Detect this case, and allow us to
fullscreen when this happens.
Don't update the stack until after setting the window->transient_for
field. Updating before will cause the stack transient-for constraint to
be missing until the next time constraints are applied.

The test runner sends a "show" command to the test clients and assumes
this was enough work done by the client to enable the compositor to map
the window. Now that we wait to show a Wayland window until the first
buffer is attached (see bug 750552), we need to make sure that we attach
a buffer before assuming that we have the final stacking order.
So, to in order to continue relying on "show" to be enough to actually
show a window, let the test client wait until it has drawn the first
frame.
This makes the tests using Wayland clients test non-flaky.

When managing a non-OR window we're required by the ICCCM to behave as
if we received a ConfigureRequest which means that we must generate a
synthetic ConfigureNotify even if the window isn't moved or resized
from its current (initial) geometry.
During MetaWindow's x11/wayland split a slight behavior change for x11
windows crept in. Before the code split, MetaWindow->rect was
initialized with the X window's geometry, but now we're not
initializing MetaWindowX11Private->client_rect which causes the checks
for whether it's necessary to move/resize the window in
meta_window_x11_move_resize_internal() to tell us that we do need to
move/resize which means we do an XConfigureWindow() call and don't
send the sythetic ConfigureNotify. But since the X window isn't really
moving, the XConfigureWindow() call doesn't cause the X server to
generate a ConfigureNotify which breaks some clients such as Java's
AWT.
We can fix this by setting MetaWindowX11Privatew->client_rect for both
OR and non-OR windows. We can set buffer_rect for non-OR windows as
well to simplify the code since it will be assigned the correct value
in meta_window_x11_move_resize_internal() .

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
is initialized and main loop is not running anymore, no client can
connect to mutter during initialization and that is what we want.

Unsetting it in meta_display_handle_event() will make the pointer
emulation checks fail on TOUCH_END event handlers across clutter
actors, the sequence should still be considered as pointer emulating
at that time.
As we don't have a way to hook this post clutter event handling,
instead unset/reset it lazily on the next pointer emulating TOUCH_BEGIN
event, the checks would already fail on other sequences, even if the
pointer emulating touch ended earlier. The only extra thing we need
to take care about is sequence collision, at which point it's safe to
just unset the stored sequence if its new incarnation isn't flagged/
deemed as pointer emulating.

The max potential number of logical monitors (i.e. MetaMonitorInfos)
is the number of CRTCs, not the number of outputs.
In cases where we have more enabled CRTCs than connected outputs we
would end up appending more MetaMonitorInfos to the GArray than the
size it was initialized with which means the array would get
re-allocated rendering invalid some MetaCRTC->logical_monitor pointers
assigned previously and thus ending in crashes later on.

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.

If a client only ever sets the hint on window creation we'd never pick

When managing window, we queue showing the window.
Under wayland, if we commit surface quickly enough,
the showing is unqueued and commit procedure takes care
of mapping and placing the window. In the oposite case,
queue is processed before client sets all we need and
then we have wrong size of window, which leads to broken placement.
Therefore force placement in queue only if the window should already
be mapped. If it is not mapped, we don't care where it is anyway.

Failing to initialize Clutter isn't something it's useful to report
into automatic bug tracking systems or get a backtrace for - in fact,
the most common case is that DISPLAY is unset or points to a
non-existent X server. So simply exit rather than calling g_error().
https://bugzilla.gnome.org/show_bug.cgi?id=757311
g_error() is the wrong thing to do when, for example, we can't find the
DRM device, since Mutter should just fail to start rather than reporting
a bug into automatic bug tracking systems. Rather than trying to decipher
which errors are "expected" and which not, just make all failure paths
in meta_launcher_new() return a GError out to the caller - which we make
exit(1).

Ubuntu ships a patch in the X server that makes the group switch
keybindings only work on key release, i.e. the X server internal group
locking happens on key release which means that mutter gets the
XKB_KEY_ISO_Next_Group key press event, does its XLockGroup() call
with a new index and then, on key release, the X server moves the
index further again.
We can work around this without affecting our behavior in unpatched X
servers by doing a XLockGroup() every time we're notified of the
locked group changing if it doesn't match what we requested.

In a HiDPI environment, all gtk+ apps will report a 2 x 2 size
increment to avoid odd size. But that does not mean they are
resizing in cells like terminals, so they resize popup should
not be shown.
Ideally, we should ignore <= scale x scale increments, but in
practice scale is 1 or 2, and even in a lo-dpi setting a 2 x 2
increment makes little sense so let's keep the patch simple.

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.

trigger menus through touch or keyboard devices.

We might get modes in XRROutputInfos that aren't in the
XRRScreenResources we get earlier. This always seems to be transient,
i.e. when it happens, the X server will usually send us a follow up
RRScreenChangeNotify where we then get a "stable" view of the world
again.
In any case, when these glitches happen, we end up with NULL pointers
in the MetaOutput->modes array which makes us crash later on. This
patch ensures that doesn't happen.

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 have been ignoring those buttons since 3.16 after they had been
broken in the default theme for a couple of versions. As nobody
appears to miss them, it's time to remove them for good.
We use a single style context to draw titlebar buttons, updating
its state according to each button's prelight state as necessary.
This assumes that the original state is neither ACTIVE nor PRELIGHT,
which means we need to reset the state after drawing to avoid
propagating the state of the last-drawn button.
Displaying all Wayland windows with the XID of 0x0 makes it hard
to figure out what is going on ... use the recently-added
window->stamp to show Wayland windows as W1/W2/W3...
Some windows, like Chromium and Steam, are technically CSD in that they
don't want a system titlebar and draw their own, but we should still
provide them with a shadow.
Both Window and XSyncCounter are XIDs which on 64 bit X clients are 8
bytes wide. But the values on the wire are 32 bit so, for these types,
we always copy 4 bytes into results->prop. As such copying them out
with a cast such as *(Window *) means that we are actually reading 8
bytes which depending on whether the higher addressed 4 bytes are zero
means that sometimes this works while others it gives us a bogus
value.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=754357
When committing a toplevel surface we might no longer have a MetaWindow
associated with it. The reason may vary but some are: a popup was
dismissed, the client attached and committed a NULL buffer to a
wl_surface with the wl_shell_surface role, the client committed a
buffer to a wl_surface which previously had an toplevel window role
which extension object was destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=755490
If the drag dest surface suddenly disappears, we may find ourselves
processing an XdndPosition message that was sent before the X11 drag
source had an opportunity to find out.
In that case mutter does know, so double check before processing the
messages.
We try to translate the atom with its corresponding mimetype both back
and forth, which actually breaks if the X11 client chose to announce the
mimetype atom. To do the translation properly, keep track on whether the
source announced the UTF8_STRING atom, and reply back with this only if
that happened.
If the wayland surface isn't available yet when we process the
WL_SURFACE_ID ClientMessage, we schedule a later function to try the
association again after we get a chance to process wayland requests.
This works fine except on cases where the MetaWindow already had a
previous surface attached (i.e. when the xwindow is reparented) since
we only break the existing association on the later function which
means that when processing the old surface's destruction we destroy
the MetaWindow and cancel the pending later function leaving us
without a MetaWindow and an invisible surface.
Fix this by detaching the old surface as soon as possible so that the
MetaWindow survives.

The saved rect is used to restore a saved window size. We need to

Calling queue_redraw() in _force_update() is not needed because
update_cursor() will do this when needed, i.e. when switching between

There is also no need to force _native_force_update() because
update_cursor() will cover this as well when needed. When not changing
cursor but only the gbm_bo, the "dirty" boolean on the gbm_bo will
trigger a redraw.

This commits refactors cursor handling code and plugs in logic so that
cursor sprites changes appearance as it moves across the screen.
Renderers are adapted to handle the necessary functionality.
The logic for changing the cursor sprite appearance is done outside of
MetaCursorSprite, and actually where depends on what type of cursor it
is. In mutter we now have two types of cursors that may have their
appearance changed:
- Themed cursors (aka root cursors)
- wl_surface cursors
Themed cursors are created by MetaScreen and when created, when
applicable(*), it will extend the cursor via connecting to a signal
which is emitted everytime the cursor is moved. The signal handler will
calculate the expected scale given the monitor it is on and reload the
theme in a correct size when needed.
wl_surface cursors are created when a wl_surface is assigned the
"cursor" role, i.e. when a client calls wl_pointer.set_cursor. A
cursor role object is created which is connected to the cursor object
by the position signal, and will set a correct texture scale given what
monitor the cursor is on and what scale the wl_surface's active buffer
is in. It will also push new buffers to the same to the cursor object
when new ones are committed to the surface.
This commit also makes texture loading lazy, since the renderer doesn't
calculate a rectangle when the cursor position changes.
The native backend is refactored to be triple-buffered; see the comment
in meta-cursor-renderer-native.c for further explanations.

If a surface doesn't have a role, the compositor will not know how, if

callback list, the compositor will respond to the client that the

Being a "XWayland window" should be considered equivalent to a role,

surface roles as defined by the Wayland protocol.

Some backgrounds don't fully fill the screen. For those backgrounds

Since mutter has two X connections and does damage handling on the
frontend while fence triggering is done on the backend, we have a race
between XDamageSubtract() and XSyncFenceTrigger() causing missed
redraws in the GL_EXT_X11_sync_object path.
If the fence trigger gets processed first by the server, any client
drawing that happens between that and the damage subtract being
processed and is completely contained in the last damage event box
that mutter got, won't be included in the current frame nor will it
cause a new damage event.
A simple fix for this would be XSync()ing on the frontend connection
after doing all the damage subtracts but that would add a round trip
on every frame again which defeats the asynchronous design of X
fences.
Instead, if we move fence handling to the frontend we automatically
get the right ordering between damage subtracts and fence triggers.

The global wl_pointer_gestures object is now created, effectively
bridging pinch/swipe gestures with clients, so they're now

Instead of moving around all the bound pointer resources for a client
when changing focus, keep all the resources bound by a client in a per

active pointer client struct instance.
This will simplify having wl_pointer extensinos sharing the pointer
focus of the wl_pointer by only having to add them to the pointer

except the stage when running nested, we do in case we hold a pointer
grab - just ignore those events instead of taking down the user's
session.
The spec says:
"A server should avoid signalling the frame callbacks if the surface is not
visible in any way, e.g. the surface is off-screen, or completely obscured
by other opaque surfaces."
We actually do have the information to do that but we are always calling
the frame callbacks in after_stage_paint. So fix that to only call when
when the surface gets drawn on screen.

The compositor maintains a ring of shared fences with the X server in order to
properly synchronize rendering between the X server and the compositor's GPU
channel. When all of the fences have been used, the compositor needs to reset
one so that it can be reused. It does this by first waiting on the CPU for the
fence to become triggered, and then sending a request to the X server to reset
the fence.
If the compositor's GPU channel is busy processing other work (e.g. the desktop
switcher animation), then the X server may process the reset request before the
GPU has consumed the fence. This causes the GPU channel to hang.
Fix the problem by having the compositor's GPU channel trigger its own fence
after waiting for the X server's fence. Wait for that fence on the CPU before
sending the reset request to the X server. This ensures that the GPU has
consumed the X11 fence before the server resets it.

If GL advertises this extension we'll use it to synchronize X with GL
rendering instead of relying on the XSync() behavior with open source
drivers.
Some driver bugs were uncovered while working on this so if we have
had to reboot the ring a few times, something is probably wrong and
we're likely to just make things worse by continuing to try. Let's
err on the side of caution, disable ourselves and fallback to the
XSync() path in the compositor.

If we can't put up a popup because grabbing the pointer fails we

This was introduced in commit c6793d477a
to prevent window self-maximisation. It turns out that that bug seems
to have been fixed meanwhile in a different way since the reproducer
in https://bugzilla.gnome.org/show_bug.cgi?id=461927#c37 now works
fine with this special handling removed.
In fact, failing to set window->fullscreen immediately when loading
the initial set of X properties causes us to create a UI frame for a
window that sets _NET_WM_STATE_FULLSCREEN.
This, in turn, might cause the fullscreen constrain code to fail if
the window also sets min_width/min_height size hints to be the monitor
size since the UI frame size added to those makes the rectangle too
big to fit the monitor. If the window doesn't set these hints, we
fullscreen it but the window will get sized such that the UI frame is
taken into account while it really shouldn't (see the reproducer
above).

Since commit 14b0a83f64 we store the

When placing a popup and the legacy transient wl_shell_surface surfaces,
take the current scale of the window into account. This commit doesn't
fix relative positioning in case a window scale would change, but since
the use case for relative positioning is mostly popups, which would be
dismissed before the parent window would be moved, it should not be that
much of a problem.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
Make meta_wayland_surface_get_toplevel_window return the top most window
in case its a chain of popups. This is to make all popups in a chain
including the top most surface have the same scale.
The reason for this is that popups are mostly integrated part of the
user interface of its parent (such as menus). Having them in a different
scale would look awkward.
Note that this doesn't affect non-popup windows with parent-child
relationship, because such windows are typically not an integral part of
the user interface (settings window, dialogs, ..) and can typically be
moved independently. It would probably make sense to make attached modal
dialogs have the same scale as their parent windows, but modal dialogs
are currently not supported for Wayland clients.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
Since we scale surface actors given what main output their toplevel
window is on, also scale the window geometry coordinates and sizes
(window->rect size and window->custom_frame_extents.top/left) in order
to make the window geometry represent what is being rendered on the
stage.

We can get this operation in some cases, for example when
we're trying to resize window that cannot be resized.

Previously a MetaWaylandOutput could be removed from the current outputs
table (by being unplugged for example). This would result in the global
object being removed and the MetaWaylandOutput instance freed, but the
wl_resource destructor would still try to remove itself from the list of
resources. Trying to do this, it'd try to access its user data pointer
which would point to the freed MetaWaylandOutput instance, and as a
result crash when trying to manipulate the freed data.
https://bugzilla.gnome.org/show_bug.cgi?id=744453
Whenever a MetaSurfaceActor is painted, update the list of what outputs
the surface is being drawed upon. Since we do this on paint, we
effectively avoids this whenever the surface is not drawn, for example
being minimized, on a non-active workspace, or simply outside of the
damage region of a frame.
DND icons and cursors are not affected by this patch, since they are not
drawn as MetaSurfaceActors. If a MetaSurfaceActor or a parent is cloned,
then we'll check the position of the original actor again when the clone is
drawn, which is slightly expensive, but harmless. If the MetaShapedTexture
instead is cloned, as GNOME Shell does in many cases, then these clones
will not cause duplicate position checks.
https://bugzilla.gnome.org/show_bug.cgi?id=744453
We may access it during painting even if it has been freed. For now,
manually unset it during the MetaWaylandSurface cleanup; in the future
make MetaWaylandSurface a GObject and make the surface pointer a weak
reference.

The elementary guys would like this as an API, and I don't see any
reason to refuse -- this is quite nice shadow painting code :)
For some reason, gobject-introspection can't seem to cope with
MetaWindowShape. I'll look into it a bit later, but for now, mark
the function it has trouble with as (skip).
It seems that when translated, paint_offset and actor_offset will always
be the same, so our translation of the clip group won't work. For now,
until I figure out what's going on here, just use the painting offset,
since that what seems to make sense to me.
I didn't write this code, though, so I don't know why the actor's
allocation was involved in this computation at all.
I tested briefly with clones (magnifier, manual cloning through the
looking glass) and couldn't find any other artifacts, so I'm going to do
this for now.
A much less hacky version of maximize / unmaximize is reimplemented
in terms of this, but it could also eventually be used for fullscreen /
unfullscreen, and tile / untile.
The comment explains it better, but Clutter tries to be smart and
repaint actors when their allocations change. Since the window group's
allocation changes when windows move around, this means that moving a
window will always cause a full-stage repaint, which is super slow.
Hack around this for now.
While nothing will completely fix X11's artifacts, this tends to look a
bit better, *especially* with mask textures that have black at the
edges (which are most of them).
It's also faster for GPUs to manage.
The only time we ever execute this code is when we're minimizing or
hiding a window, in which case we should respect stacking order.
This fixes weird "bugs" where windows from the same app magically pop up
over other windows.
We should not be setting random output properties like this.
Use the function we just introduced to only set the underscan flag when
it's actually supported.
So that clients such as the control center can decide to hide an
underscanning checkbutton when the output does not support it.
Support in the KMS / native backend to come later...
This is an extremely niche feature, and conflicts with the rest of our
interface being consistent about not allowing resizing while tiled or
maximized.
A window may be hidden even if not minimized itself, for instance
when an ancestor is minimized. As meta_window_focus() will refuse
to actually focus the window in that case, don't pick it in the first
place.

Firstly, this patch makes MetawaylandDataSource a GObject. This is in
order to easier track its lifetime without adding destroy signals etc. It
also makes the vfunc table GObject class functions instead while at it,
as well as moves protocol specific part of the source into their own
implementations.
An important part of this patch is the change of ownership. Prior to this
patch, MetaWaylandDataDevice would kind of own the source, but for
Wayland sources it would remove it if the corresponding wl_resource was
destroyed. For XWayland clients it would own it completely, and only
remove it if the source was replaced.
This patch changes so that the protocol implementation owns the source.
For Wayland sources, the wl_resource owns the source, and the
MetaWaylandDataDevice sets a weak reference (so in other words, no
semantical changes really). For XWayland sources, the source is owned by
the selection bridge, and not removed until replaced or if the client
goes away.
Given the changes in ownership, data offers may now properly track the
lifetime of a source it represents. Prior to this patch, if an offer with
an XWayland source would loose its source, it wouldn't get notified and
have an invalid pointer it would potentally crash on. For Wayland
sources, an offer would have a weak reference and clean itself up if the
source went away. This patch changes so the behavior is consistent,
meaning a weak reference is added to the source GObject so that the offer
can behave correctly both for Wayland sources and XWayland sources.
https://bugzilla.gnome.org/show_bug.cgi?id=750680
When a possible drag dest client crashes during DnD, it may happen
we receive first the destroy notification for the data_device, and
later the notification for the focus surface. When this happens we
unset the drag_focus_data_device first, and later on
meta_wayland_drag_grab_set_focus(grab, NULL) we assume it still
exists when sending the leave event, leading to mutter crashing
right after.
So, as we don't receive any ordering guarantees about resource
destruction, just prepare the meta_wayland_drag_grab_set_focus()
paths for this.
It seems that fglrx sometimes gives us absolute junk when requesting the
outputs, and if we don't trap errors, we'll just crash when trying to
configure a junk output. Use xcb so errors simply get ignored.
For enter / leave events, which we use in the UI code, we need to make
sure that these coordinates are root-relative as well, otherwise the
cursor when entering frames might be incorrect.
Going from fullscreen to unfullscreen involves a frame border size, so
in order to properly interpret the saved rect size, we need to make sure
that the frame borders are fully up to date.
When we're unredirected, we don't have a pixmap, and thus our allocation
becomes 0x0. So when events come in, they pass right through our actor,
going to the one underneath in the stack.
Fix this by having a fallback size on the shaped texture actor when
we're unredirected, causing it to always have a valid allocation.
This fixes clicking on stuff in sloppy / mouse mode focus.
In commit cc5def1, buttons were changed from GdkRectangles to
MetaButtonSpace units, but the corresponding memset hack was not.
This means that the clickable portion of the unshade rectangle
was always set to uninitalized memory. The effects of this were
random, but in cases where the moon is aligned just right, the
rectangle would graze over the borders, and so it would take priority
over other borders and show a pointer cursor instead of a resize
cursor.
Since we're using xcb now, not Xlib, it doesn't have the stupid silly
thing where it copies all 32-bit data to 64-bit data to match the
long-y-ness of it.
It seems the largest possible value is to be passed, so actually pass
that instead. Note that even though the name of the xcb_get_property
parameter is called 'long_length' its actually a uint32_t.

The monitors info structure is created from the tiled outputs
and this is used as the central storage for info about a monitor
as opposed to the output state.
It appears at least the EDID mm w/h is for the whole monitor and
not per tile.
this just adds backend support for retrieving the tile
information from X11 (randr 1.5) and native backends.
It stores the tiling information into the output struct.
When DnD is started from an X11 client, mutter now sets up an special
grab that 1) Ensures the drag source keeps receiving events, and 2)
Moves an internal X Window over wayland clients as soon as the pointer
enters over these.
That window will act as the X-side peer for the currently focused
wayland client, and will transform XdndEnter/Position/Leave/Drop
messages into wayland actions. If DnD happens between X11 clients,
the window will be moved away and unmapped, to let these operate as
usual.

window->is_alive isn't initialized explicitly so it defaults to FALSE
meaning that if the first ping fails we'd short circuit and not show

We could initialize the variable to TRUE but in fact we don't even
need the variable at all since our dialog management is enough to
manage all the state we need, i.e. we're only interested in knowing
whether we're already displaying a delete dialog.
This does change our behavior here since previously we wouldn't
display the dialog again if the next ping failed after the dialog is
dismissed but this was arguably a bug too since in that case there
wouldn't be a way to kill the window after waiting for a while and the
window kept being unresponsive.

This piece of code hooks in both wl_data_device and the relevant X
selection events, an X11 Window is set up so it can act as the clipboard
owner when any wayland client owns the selection, reacting to
SelectionRequest events, and returning the data from the wayland client
FD to any X11 requestor through X properties.
In the opposite direction, SelectionNotify messages are received,
which results in the property contents being converted then written
into the wayland requestor's FD.
This code also takes care of the handling incremental transfers through
the INCR property type, reading/writing data chunk by chunk.

Expose it partly (in internal headers anyway), and pass a vtable for the
data source functions, the wayland vfuncs just delegate operations on the
wl_data_source resource. The resource has been also made optional, although
it'll be present on all data sources from wayland clients.
The ownership/lifetime of the DnD data source has also changed a bit,
belonging now to the MetaWaylandDataDevice like the selection one does, as
we can't guarantee how long it will be needed after the grab is finished,
it will be left inert and replaced the next time DnD is started at worst.
This allows the creation of custom/proxy data sources, which will turn out
useful for X11 selection interoperation.
https://bugzilla.gnome.org/show_bug.cgi?id=738312
We'll need to get the value of some properties. Fail if the number of
items returned is less than we expect and warn if it exceeds it so
that we can easily find out if items are added to a property later and
fix it.
The corresponding wl_notify field for destroy_data_device_icon()
is drag_grab->drag_icon_listener, otherwise we're fetching a pointer
that's slightly off where we want.
When running as an X11 compositor we do this for every event we see on
the X event stream. As a wayland compositor we don't go through that
code path but since we see all events we can easily do this on motion
events.
In fact, we don't even need this caching when we're a wayland
compositor since we can always find where the pointer is without a
round trip but we're sharing the current monitor logic with the X
path so let's keep it as is for now.

Since the frame is the window that's redirected, there's no reason for
it to match the root window. There *is*, however, a big incentive to
match the window's visual, since not doing so might trigger automatic
redirection.
On a specific platform, we construct a depth-32 root window, and stick a
depth-24 child window inside it. The frame ends up being created
depth-32, not depth-24, so we get automatic redirection.
since commit 8c16ac47c1, we started
creating the login screen on display 1024 instead of display 0.
This defeats this logic in try_display:
display++;

* abort in this case. */

screen in most setups, but we should still fix the bug.

before having attached any buffers. Before we'd not notify the client of
the new expected size if the previous size was 0x0 as it would normally
mean we'd resize to 1x1, but since this is not always the case, only
avoid notifying the client if the previous size was 0x0 and the result
is 1x1.

As we opt out of GTK+/Clutter's HiDPI handling, we need to apply the
window scaling factor manually to decorations, both the geometry and
when drawing.

If the wl_surface resource happens to be destroyed before any other
role resource, the destructor for the latter will attempt to
access/modify random memory.
Fix this by ensuring the associated resources are destroyed on the
wl_surface destructor, this will free all associated memory and
remove the resources ahead of their imminent destruction.

In 3.16, GDM keeps a login screen running on vt1.
This login screen starts an Xwayland instance.
Since it's the first X server to start, it gets
the prized :0 display number.
This commit works around that problem, for now,
by having GDM's display number start at 1024.

With all input events being handled through clutter, this only confuses
things, and most nominally, coerces touch events through places we didn't
intend to, like the window frame.
This makes again all touch events only handled in the passive grab on X11,
while the rest stays pointer (emulated) only.
https://bugzilla.gnome.org/show_bug.cgi?id=745335
On startup, the cursor is kept hidden if there's any touchscreen available.
If the device that was last interacted is removed, we check on available
pointing devices though, so we don't possibly hide the pointer if there are
further mice/touchpads/etc.
Devices being added don't update cursor visibility, we wait for the user
interacting with those instead.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
On X11, calling this function on meta_display_handle_events() will not catch
mouse events happening over clients, so poke directly in the backend for
XI_DeviceChanged events, which mutter will get on device switches.
The code has been slightly refactored so we deal with XIEvents at a single
handle_input_event() function.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
This function can be used to trigger changes depending on the device type
that is currently emitting the events. So far, it is used to switch cursor
visibility on/off on touchscreen interaction.
A "last-device-updated" signal has also been added, in order allow hooking
other behavior changes (eg. OSK) when the last device changes.

Since commit 6e06648f7, we start out with the invisible frame parts
only, and then add the unconstrained rect's height (which consists of
the visible parts of both frame and client window) *unless* the window
is shaded. While we indeed don't want to add the client height in that
case, we need to explicitly include the visible frame parts now.

There is no good reason to do so, besides a nice way to check whether
a particular button is enabled. However there are legitimate reasons
for overdrawing like box-shadows or outlines, so remove the clip.
The initial pointer position is set by clutter. At the moment it
is the point 16x16 on the screen. But this point is not always
in the visible area on monitors (the monotors can be arranged in
many different ways).
https://bugzilla.gnome.org/show_bug.cgi?id=745752
Otherwise the pointer might be "lost" outside the visible area. Note
that the constraining code only ensures the pointer doesn't leave the
visible area but if the pointer is already outside because the rug was
pulled under it then it doesn't do anything.

The timer to blacklist the window from frame sync is set at the time of
issuing the sync request, but not removed until the client replies to
the most recent wait serial.
This means that if the client is slowly catching up, the timeout would
fire up regardless of the client slowly updating the alarm to older
values.
Fix this by ensuring the timeout is reset everytime the sync request
counter is updated, to acknowledge the client is not irresponsive,
just slow.

MetaWaylandFrameCallback has been added a surface field, which is then
checked when destroying the surfaces. This prevents unintended callbacks
to run after a surface has been destroyed.

Implicit conversion from int to float is not supported by
GLSL ES.

4:17: S0001: Type mismatch in arithmetic operation between 'int' and 'float'

In order to switch to the correct surface actor scale given the monitor
the surface is on, without relying on the client committing a new state
given some other side effect, sync the surface actor state when the main
monitor associated with the corresponding window changed.
https://bugzilla.gnome.org/show_bug.cgi?id=744933
Since the surface actor knows more about how it draws itself, instead of
pushing texture state (buffer and scale), input region and opaque region
from MetaWaylandSurface after having transformed into what the surface
actor expects, make the surface actor set its own state given what state
the Wayland surface is in.

DRM objects like connectors and encoders might change at any time, in
particular they might become invalid between drmModeGetResources() and
getting the actual objects in which case they'll be NULL. Be defensive
against that.
Note that, if this happens, we should get another udev event soon
which will cause us to update our state.

Doing this on manage() allows the common MetaWindow initialization to
do the right thing for popups like setting skip_taskbar and
skip_pager.
In particular this avoids gnome-shell's app tracker to create a new
ShellApp instance for every popup.

Before commit ac448bd42b the pointer,
keyboard, and touch objects were initialized when the seat was created.
Now they're initialized later, when the clutter device manager finds and
loads them.
This commit makes sure we don't try to access those objects if they
aren't initialized.

The wayland seat event handlers get sent events that
aren't strictly interesting to them (such as events for
hardware devices the seat doesn't support and events for
virtual devices that the seat needs to ignore).
This commit makes sure all uninteresting events get ignored.
Kerbel Space Program, and perhaps some other SDL-based programs, use
a really dumb way of specifying icons, which is totally
non-standards-compliant.
The ICCCM specifies that the icon_pixmap field of WM_HINTS should be a
1-bit-deep Pixmap, but we've seen applications set it to a pixmap of the
root depth as well, so we support that.
Kerbel Space Program seems to use it with a 32-bit depth Pixmap,
signifying ARGB32 (which it is), along with a 1-bit icon_mask, which
crashes us.
Keep in mind that Pixmaps, by definition, have no Visual attached, so
we simply have to make a guess at the correct visual based on the
depth. Do that by assuming that a depth-32 visual always means ARGB32,
which is a pretty safe bet.
If a client creates an xdg_popup given a parent that is a xdg_popup that
is not the most top one in the grab chain, send the
not_the_topmost_popup error.
Also fail a client who destroys a popup that is not the top most one.

We'll want to expose popup logic outside of meta-wayland-pointer.c and
one day we'll also probably want to add touch support for popups, so
lets move it to its own file. There are no significant semantical
changes, only refactoring.
https://bugzilla.gnome.org/show_bug.cgi?id=744452
The current ordering updates the clip shape of the composite overlay
window after unredirecting the target window. This has the effect of
forcing X to clear the target window and sending an expose to the
application to repaint - causing an unsightly flash. If we update the
shape first, then unredirect, X restores the background of the root
window (sending no expose events as no one is interested) and the
background is typically NONE for the root window. Then the unredirect
paints the contents of the composite backing pixmap over top without
requiring a round trip and waiting for the client to repaint - thus no
flashing.

This just exposes the type and the singleton getter necessary to make

We're locked to frame sync anyway, so it doesn't make sense to try to
redraw early. In casual testing, this seems to actually make things
faster, as well.
The commit 97a69cee5a broke the caching of
the surface state when because the frame_callback_list target state was
overwritten after the content had been moved to it.
This commit fixes it by moving the frame list addition after the copy. We
also need to initialize the list since the plain copy put garbage in it.

When looking for space to place a new window, other non-minimized

the current check does not work correctly when the placed window is
located on all workspaces, so handle that case explicitly.

When running as a dispay server pointer barriers are a server side
feature and requires no client interaction of any sort. This patch

server on the native backend. Running as a display server using the X11
backend is currently not supported.

For each device that can be mapped (touchscreens, tablets), the output
will be fetched from settings and matched with the currently connected
ones. If a match is found, the device matrix will be found out from the
output configuration and set on the device.
This is also updated both individually for newly connected devices, and
collectively on output configuration changes.
