We do some things when binding to a socket fails (closing the fd,
logging, unlinking files, ...) those might affect errno in some
or other way, so it might no longer be EADDRINUSE even if we later
try to make those non fatal.
It seems better to check errno soon after the failure, and don't
rely on it in any way at a later point. All error paths in
bind_to_abstract_socket() also have early logging, which also might
help figure out better the point of failure when the socket fails
to be created.

Support changing the mouse and trackball acceleration profile. This
makes it possible to for example disable pointer acceleration by
choosing the 'flat' profile.
This adds an optional dependency on gudev. Gudev is used by the X11

support, the accel profile settings has have effect for mouse devices.
Trackball still uses the "strstr" approach, since udev doesn't support

If the compiler cannot figure out that the condition for setting
the dev variable is the same as the condition for accessing it,
it will complain about potential uninitialized use.
We must lookup the mode switch serial for the group where the button
belongs to. Also, avoid the changes if the client requests setting
the feedback for buttons owned by the compositor.
We assumed that each group could only have 1 strip and/or ring, because
accounting is performed per group, so we could not assume the real
index for anything above 1. Get rid of this restriction, now that
MetaWaylandTabletPad does its own accounting of rings/strips, alongside
groups.
This is best for 2 reasons:
- It's feels cleaner doing first creation of rings/strips and then
the group assignment. The other option is making groups iterate
other all rings/strips and selectively skip those not meant for
it, which sounds somewhat redundant.
- Some minimal accounting of rings/strips without group restrictions
is needed for meta_wayland_tablet_pad_get_label().
The rings/strips memory is now owned by MetaWaylandTabletPad instead
of groups, which is sort of meaningless since all are meant to go
at the same time.
There may be external/compositor-specific reasons to trigger the
pad OSD. Expose this call so the pad OSD can be triggered looking
up the right settings, monitor, etc...
This API will be used from the gnome-shell pad OSD implementation, in order
to show the actions that currently apply to every button/ring/strip in the
tablet.
It does nothing at the moment, but can be hooked into MetaWaylandTabletPad
now. For X11, we need to trigger these for the pad events we receive from
the passive pad button grabs.
This function will be useful for the wayland implementation, because buttons
are mapped at the time of sending those through the wire.
As x11/wayland implementations differ here, this function will be useful for
the wayland implementation, as the action is handled lat
Some settings make no sense on external tablets, and others make
no sense in display/system-integrated tablets. Perform those checks
so we don't end up with possibly broken configuration.
Given that information defines largely how such devices are to be
configured, it makes sense to have that information at hand. A getter
has been also added for the places where it could be useful, although
it will require HAVE_LIBWACOM checks in callers too.
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.
When launching a GNOME session from a text-mode VT, the logind session
type is unlikely to be set to either "wayland" or "x11". We search for a

$XDG_SESSION_TYPE. As a fallback, we also test $DISPLAY in case of a
"tty" logind session to support starting through xinit. Ideally, such
setups should set XDG_SESSION_TYPE=x11.
If no supported session type is found, we throw an error.

They are already effectively interchangeable so this should reduce
pointless casts.
Just like in GDK though, we need to keep the old definition for
instrospection to be able to include the struct's fields.
By creating a pending gbm/EGL surface pair, only setting it on
swap-buffers, we would draw onto a buffer on the old surface, then swap
the buffer from the new surface, causing the first frame after a
hot-plug always having no content.
This was in the past not very noticable since some non-deterministic but
frequent side effect in gnome-shell caused hot-plugging to always render
two new frames, but after "Introduce regional stage rendering", this
side effect did not occur as often, thus making it more visible.
This commit updates the current gbm/EGL surface pair before painting a
frame, so that when the frame is painted, the surface with the correct
size is used and the buffer from correct surface is swapped.

CoglFrameInfo is a frame info container associated with a single

Add support for drawing a stage using multiple framebuffers each making
up one part of the stage. This works by the stage backend
(ClutterStageWindow) providing a list of views which will be for
splitting up the stage in different regions.
A view layout, for now, is a set of rectangles. The stage window (i.e.
stage "backend" will use this information when drawing a frame, using
one framebuffer for each view. The scene graph is adapted to explictly
take a view when painting the stage. It will use this view, its
assigned framebuffer and layout to offset and clip the drawing
accordingly.
This effectively removes any notion of "stage framebuffer", since each
stage now may consist of multiple framebuffers. Therefore, API
involving this has been deprecated and made no-ops; namely
clutter_stage_ensure_context(). Callers are now assumed to either
always use a framebuffer reference explicitly, or push/pop the
framebuffer of a given view where the code has not yet changed to use
the explicit-buffer-using cogl API.
Currently only the nested X11 backend supports this mode fully, and the
per view framebuffers are all offscreen. Upon frame completion, it'll
blit each view's framebuffer onto the onscreen framebuffer before
swapping.
Other backends (X11 CM and native/KMS) are adapted to manage a
full-stage view. The X11 CM backend will continue to use this method,
while the native/KMS backend will be adopted to use multiple view
drawing.

the legacy method. Eventually only the X11 Compositing Manager backend

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,

is moving a window in response to motion events.

This layer isn't really being used and in fact, it causes

When restarting (X compositor only, obviously), we want to keep
the same window focused. There is code that tries to do this by
calling XGetInputFocus() but the previously focused window will
almost certainly not still be focused by the time we get to the
point where we call XGetInputFocus(), and in fact, probably was
no longer correct after the previous window manager exited, so
the net result is that we tend to focus no window on restart.
A better approach is to leave the _NET_ACTIVE_WINDOW property
set on the root window during exit, and if we find it set when
starting, use that to initialize focus.

Emit a signal so that interested parties can recreate their FBOs and
queue a full scene graph redraw to ensure we don't end up showing

suitable GL context. For now we only make use of it with the X backend
since the only driver with which this is useful is NVIDIA.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=768007
Frames are painted on the frame window according to the GTK+ theme.
Depending on the target's visual, this means either drawing over
a black destination or a fully transparent one. So in cases where
the theme doesn't paint decorations with full opacity, decorations
for windows with an rgba visual look different from those with a
non-rgba visual. Using an rgba visual for all frames independent
from the client's visual can potentially break clients, so our
only option for a consistent appearance is to explicitly initialize
the frame background to black before painting the theme's decoration
on top.
https://bugzilla.gnome.org/show_bug.cgi?id=745060
The GTK+ theme may draw parts of the decorations outside the actual
frame. Since commit f9db65f47f we make sure that the frame is big
enough to account for any overdrawing, however as we still clip the
cairo context to the actual frame before drawing the decorations,
those parts aren't actually painted.
This issue is not very obvious for most frames, as they use a non-rgba
visual where the unpainted parts appear black, which gives the expected
result with many themes once the shape mask is applied (as the mask does
include any overdrawn parts). For frames using an rgba visual however,
unpainted parts are transparent, so any overdrawn decorations are clearly
missing.
Fix this by only clipping out the client area when drawing decorations.
https://bugzilla.gnome.org/show_bug.cgi?id=745060
We ignore all damage while a surface is frozen and queue a full
update instead once it's thawed. While not super efficient, this
isn't overly bad for the intended case of catching up with any
updates that happened during a compositor effect. However when
extended frame sync is used, surfaces are also frozen while the
client is drawing a frame, in which case the current behavior is
pretty damaging (pun intended), as we end up redrawing the entire
window each frame. To address this, keep track of the actual damage
we ignore and apply it when the surface is thawed.

The result flag needs to be marked as moved even for pending moves,

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

This makes us behave the same both on bind and when an output

Stacking hidden X windows below the guard window is a necessity to
ensure input events aren't delivered to them. Wayland windows don't
need this because the decision to send them input events is done by us
looking at the clutter scene graph.
But, since we don't stack hidden wayland windows along with their X
siblings we lose their relative stack positions while hidden. As
there's no ill side effect to re-stacking hidden wayland windows below
the X guard window we can fix this by just doing it regardless of
window type.

All the upper layers are prepared for multiple onscreen cursors, but
this. All MetaCursorRenderers created would poke the same internal
MetaOverlay in the stage.
This will lead to multiple cursor renderers resorting to the "SW"
rendering paths (as it can be seen with tablet support) to reuse the
same overlay, thus leading to flickering when a different
MetaCursorRenderer takes over the overlay.
Fix this by allowing per-cursor-renderer overlays, their lifetime
is attached to the cursor renderer, so is expected to be tear down
if the relevant device (eg. tablet) disappears.
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.
Sadly, GLib's autoptr cleanup macros cannot be detected by the C
pre-processor, because they generate a function. This means that we are
forced to bump up the dependency on GLib 2.49, in order to build against
a newer version of gdbus-codegen.
Starting from GLib 2.49, the gdbus-codegen tool automatically generates
the auto cleanup symbols for the GDBus proxy and skeleton interfaces.
Since we don't depend on a specific version of GLib we need to
conditionally generate the auto cleanup symbols in case an older version
of gdbus-codegen is used when building Mutter.

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.

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.

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).
