meta_shaped_texture_update_area() is a private function that
is exposed in the public headers. It is not used anywhere
outside Mutter, and should really be in the private header.
Move it to the private header.

Now that MetaShapedTexture is not a ClutterActor anymore, it does
not make sense to make it a MetaCullable semi-implementation. This
is, naturally, a responsibility of MetaSurfaceActor, since now
MetaShapedTexture is a ClutterContent and as such, it only cares
about what to draw.
Move the MetaCullable implementation of MetaShapedTexture to
MetaSurfaceActor.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
By implementing ClutterContent, it is expected that
MetaShapedTexture can draw on any actor. However,
right now this is not possible, since it assumes
that the drawing coordinates and sizes of the actor
are synchronized with its own reported width and
height.
It mistakenly draws, for example, when setting an
actor's content to it. There is no way to trigger
this wrong behavior right now, but it will become
a problem in the future where we can collect the
paint nodes of MetaShapedTexture as part of other
ClutterContent implementations.
Use the allocation box passed by the actor to draw
the pipelines of MetaShapedTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
Now that MetaShapedTexture is a ClutterContent implemetation that
is aware of its own buffer scale, it is possible to simplify the
event translation routines.
Set the geometry scale in MetaSurfaceActor, and stop adjusting the
surface scale when translating points. Also remove the now obsoleted
meta_wayland_actor_surface_calculate_scale() function.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore

With the addition of xauth support (commit a8984a81c), Xwayland would
rely only on the provided cookies for authentication.
As a result, running an Xclient from another VT (hence without the
XAUTHORITY environment variable set) would result in an access denied.
The same on X11 is granted because the local user is automatically
granted access to Xserver by the startup scripts.
Add the local user to xhost at startup on Xwayland so that the user can
still run a client by setting the DISPLAY as long as it's the same user
on the same host.

Introduce MetaCompositorX11, dealing with being a X11 compositor, and

When double clicking to un-maximize an X11 window under Wayland, there
is a race between X11 and Wayland protocols and the X11 XConfigureWindow
may be processed by Xwayland before the button press event is forwarded
via the Wayland protocol.
As a result, the second click may reach another X11 window placed right
underneath in the X11 stack.
Make sure we do not forward the button press event to Wayland if it was
handled by the frame UI.

Add meta-kms and meta-monitor-manager-kms listener for the udev
device-removed signal and on this signal update the device state /
re-enumerate the monitors, so that the monitors properly get updated
to disconnected state on GPU removal.
We really should also have meta-backend-native remove the GPU itself
from our list of GPU objects. But that is more involved, see:
https://gitlab.gnome.org/GNOME/mutter/issues/710
This commit at least gets us to a point where we properly update the
list of monitors when a GPU gets unplugged; and where we no longer
crash the first time the user changes the monitor configuration after
a GPU was unplugged.
Specifically before this commit we would hit the first g_error () in
meta_renderer_native_create_view () as soon as some monitor
(re)configuration is done after a GPU was unplugged.

drmModeGetConnector may fail and return NULL, this may happen when
a connector is removed underneath us (which can happen with e.g.
DP MST or GPU hot unplug).
Deal with this by skipping the connector when enumerating and by
assuming it is disconnected when checking its connection state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
drmModeGetCrtc may fail and return NULL. This will trigger when
meta_kms_crtc_update_state gets called from meta_kms_update_states_sync
after a GPU has been unplugged leading to a NULL pointer deref causing
a crash.
This commit fixes this by checking for NULL and clearing the current_state
when NULL is returned.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
Before this commit meta_kms_crtc_read_state was overwriting the
entire MetaKmsCrtcState struct stored in crtc->current_state including
the gamma (sub)struct.
This effectively zero-s the gamma struct each time before calling
read_gamma_state, setting the pointers where the previous gamma values
were stored to NULL without freeing the memory. Luckily this zero-ing
also sets gamma.size to 0, causing read_gamma_state to re-alloc the
arrays on each meta_kms_crtc_update_state call. But this does mean that
were leaking the old gamma arrays on each meta_kms_crtc_update_state call.
This commit fixes this by making meta_kms_crtc_read_state only overwrite
the other values in the MetaKmsCrtcState struct and leaving the gamma
sub-struct alone, this will make read_gamma_state correctly re-use the
gamma tables if the gamma table size is unchanged; or re-alloc them
(freeing the old ones) if the size has changed, fixing the memory leak.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
The "device-added" signal should use g_cclosure_marshal_VOID__OBJECT not
g_cclosure_marshal_VOID__VOID.
Instead of fixing this manually, simply replace the closure function for
both signals with NULL, glib will then automatically set the correct
va_marshaller.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/713
Some meta_later operations may happen across XWayland being shutdown,
that trigger MetaStackTracker queries for X11 XIDs. This crashes as
the MetaX11Display is already NULL.
Return a NULL window in that case, as in "unknown stack ID".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
There may be cases where a X11 client does not spawn any X11 windows (eg.
simple clients like xinput --list, or xlsclients), in this case the Xwayland
server would remain running until X11 windows happen to come and go in the
future.
Firing the shutdown timeout on restart caters for this, and would be undone
if the client maps X11 windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/728
Where the prepare_auth_file() call is, it does create a new one on every
respawn of Xwayland. This is not benefitial, as the XAUTHORITY envvar is
already fixed in the session.
Only create the XAuthority file once, and reuse it on future Xwayland
respawns.

When primary_offer_receive checks if the requested mime_type is supported,
it should check against the list of mime-types supported by the
primary-selection, instead of the list for the clipboard.

not working.

We only listen for those so we know there's no more X11 clients that we
should keep the Xwayland server alive for. Check first that we really did
request Xwayland to be handled on demand for this, otherwise the check is
superfluous, even harmful.
https://gitlab.gnome.org/GNOME/mutter/issues/719
The Xwayland manager now has 4 distinct phases:
- Init and shutdown (Happening together with the compositor itself)
- Start and stop
In these last 2 phases, handle orderly initialization and shutdown
of Xwayland. On initialization We will simply find out what is a
proper display name, and set up the envvar and socket so that clients
think there is a X server.
Whenever we detect data on this socket, we enter the start phase
that will launch Xwayland, and plunge the socket directly to it.
In this phase we now also set up the MetaX11Display.
The stop phase is pretty much the opposite, we will shutdown the
MetaX11Display and all related data, terminate the Xwayland
process, and restore the listening sockets. This phase happens
on a timeout whenever the last known X11 MetaWindow is gone. If no
new X clients come back in this timeout, the X server will be
eventually terminated.
The shutdown phase happens on compositor shutdown and is completely
uninteresting. Some bits there moved into the stop phase as might
happen over and over.
This is all controlled by META_DISPLAY_POLICY_ON_DEMAND and
the "autostart-xwayland" experimental setting.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
When rushing to unmanage X11 windows after the X11 connection is closed/ing,
this would succeed at creating a stack operation for no longer known windows.
Simply avoid to queue a stack operation if we know it's meaningless.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
Unmanaging the windows may trigger stack operations that we later try
to synchronize despite being in dispose() stage. This may trigger
MetaStackTracker warnings when trying to apply those operations.
Switching destruction order (First dispose the X11 stack representation,
then unmanage windows) won't trigger further stack changes on X11 windows
after having signaled MetaDisplay::x11-display-closing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
What "restart" means is somewhat different between x11 and wayland
sessions. A X11 compositor may restart itself, thus having to manage
again all the client windows that were running. A wayland compositor
cannot restart itself, but might restart X11, in which case there's
possibly a number of wayland clients, plus some x11 app that is
being started.
For the latter case, the assert will break, so just make it
conditional. Also rename the function so it's more clear that it
only affects X11 windows.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
In the case mutter is a x11 compositor, it doesn't matter much
since the stack tracker will go away soon. In the case this is a
wayland compositor with mandatory Xwayland, it matters even less
since the session would be shutting down in those paths.
But if this a wayland compositor that can start Xwayland on demand,
this is even harmful, as the MetaStackTracker should be cleared of
x11 windows at this moment, and we actually did right before dispose
on ::x11-display-closing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
If the display is closed prematurely, go through all windows that
look X11-y and remove them for future calculations. This is not
strictly needed as Xwayland should shut down orderly (thus no client
windows be there), but doesn't hurt to prepare in advance for the
cases where it might not be the case.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
We don't strictly need it for wayland compositors, yet there are
paths where we try to trigger those passive grabs there. Just
skip those on the high level code (where "is it x11" decisions
are taken) like we do with passive button grabs.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/709
Commit 09bab98b1e tried to avoid several workspace changes while in
window construction, but it missed a case:
If we have a window on a secondary monitor with no workspaces enabled
(so it implicitly gets on_all_workspaces = TRUE without requesting it)
and trigger the creation of a second window that has the first as
transient-for, it would first try to set the first workspace than the
transient-for window and then fallback to all/current workspace.
After that commit we only try to set the same workspace than the
transient-for window, but it gets none as neither is on a single workspace,
nor did really request to be on all workspaces.
Fixes crashes when opening transient X11 dialogs in the secondary monitor.

Similar to gtk commit f507a790, this ensures that the valist variant of
the marshaller is used. From that commit's message:
```
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
```
https://gitlab.gnome.org/GNOME/mutter/merge_requests/697
By putting `NULL` as the C marshaller in `g_signal_new`, you
automatically get `g_cclosure_marshaller_generic`, which will try to
process its arguments and return value with the help of libffi and
GValue.
Using `glib-genmarshal` and valist_marshallers, we can prevent this so
that we need less instructions for each signal emission.

The MetaBackgroundActor was ignoring the unobscured area altogether,

Wayland clients do this through the opaque region in the surface
actor. However X11 clients were considered fully transparent for
culling purposes, which may result in mutter painting other bits
of the background or other windows that will be painted over in
reality.

We want to clip it away if 1) The window is fully opaque or
2) If it's translucent but has a frame (as explained in the comment
above). The code didn't quite match and we were only applying it on
case #2.
Case #1 is far more common, and saves us from pushing some drawing
that we know will be covered in the end.

We first set the workspace to the transient-for parent's, and then
try to set on the current workspace. If both happen, we double the

The default configuration of libinput-gestures utility invokes wmctrl to
switch between desktops. It uses wmctrl because this works on both Xorg
and Wayland (via XWayland). Unfortunately, this generates the following
warning message every time, in both Xorg and Wayland desktops:
"Received a NET_CURRENT_DESKTOP message from a broken (outdated) client
who sent a 0 timestamp"
The desktop switch still works fine. The tiny code change here removes
this specific warning because, as the prefacing code comment originally
said and still says, older clients can validly pass a 0 time value so
why complain about that?
I also refactored the "if (workspace)" code slightly to avoid the double
test of the workspace value.
This is submitted for MR
https://gitlab.gnome.org/GNOME/mutter/merge_requests/671.
On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.
However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.
Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/647
Some special modifiers (typically "Control_L" used for locate-pointer in
mutter/gnome-shell or "Super_L" for overlay) must be handled separately
from the rest of the key bindings.
Add a new flag `META_KEY_BINDING_NO_AUTO_GRAB` so we can tell when
dealing with that special keybinding which should not be grabbed
automatically like the rest of the keybindings, and skip those when
changing the grabs of all keybindings.

Glib stopped providing any fallback implementations on systems without
memmove() all the way back in 2013. Since then, the symbol is a simple

Starting with commit 2db94e2e we try to focus a fallback default focus window
if no take-focus window candidate gets the input focus when we request it and
we limit the focus candidates to the current window's workspace.
However, if the window is unmanaging, the workspace might be unset, and we could
end up in deferencing a NULL pointer causing a crash.
So, in case the window's workspace is unset, just use the currently active
workspace for the display.

This is important when using a touchscreen or stylus instead of a mouse
or touchpad. If the cursor only gets hidden and the focus stays the
same, the window will still send hover events to the UI element under
the cursor causing unexpected distractions while interacting with the
touchscreen.
Fix this by emitting a visibility-changed signal from the cursor tracker
which then triggers a focus surface sync and always set the focus
surface to NULL when it's synced while the cursor is hidden.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/448
Allow checking whether the pointer is visible without accessing the
trackers internal is_showing property. While we don't need this just yet
for reading the visibility inside meta-wayland-pointer, it's useful when
implementing the logic to remove Clutter's focus when the cursor goes
hidden later.

COPY_MODE_PRIMARY has two paths, automatically chosen. For debugging purposes,
e.g. why is my DisplayLink screen slowing down the whole desktop, it will be
useful to know which copy path is taken. Debug prints are added to both when
the primary GPU copy succeeds the first time and when it fails the first time.
This is not the full truth, because theoretically the success/failure could
change every frame, but we don't want to spam the logs (even in debug mode)
every frame. In practise, it should be rare for the success or failure to ever
change. Hence, saying what happened on the first time is enough. This does
indicate if it ever changes even once, too, so we know if that unexpected thing
happens.
The debug prints are per secondary GPU since there could be several.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
When the preferred path META_SHARED_FRAMEBUFFER_COPY_MODE_SECONDARY_GPU cannot
be used, as is the case for e.g. DisplayLink devices which do not actually have
a GPU, try to use the primary GPU for the copying before falling back to
read-pixels which is a CPU copy.
When the primary GPU copy works, it should be a significant performance win
over the CPU copy by avoiding stalling libmutter for the duration.
This also renames META_SHARED_FRAMEBUFFER_COPY_MODE_* because the new names are
more accurate. While the secondary GPU copy is always a GPU copy, the primary
copy might be either a CPU or a GPU copy.

This bit of code was more or less duplicated in meta-renderer-native-gles3.c
and meta-wayland-dma-buf.c. Start consolidating the two implementations by
moving the *-gles3.c function into meta-egl.c and generalizing it so it could
also accommodate the meta-wayland-dma-buf.c usage.
The workaround in the *-gles3.c implementation is moved to the caller. It is
the caller's responsibility to check for the existence of the appropriate EGL
extensions.
Commit 6f59e4858e worked around the lack of
EGL_EXT_image_dma_buf_import_modifiers with the assumption that if the modifier
is linear, there is no need to pass it into EGL. The problem is that not
passing a modifier explicitly to EGL invokes implementation-defined behaviour,
so we should not have that workaround in meta-egl.c.
This patch intends to be pure refactoring, no behavioral changes. The one
change is the addition of g_assert to catch overwriting arbitrary memory.

Using the master device, as we did, won't yield the expected result when
looking up the device node (it comes NULL as this is a virtual device).
Use the slave device, as the g-s-d machinery essentially expects.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/678
The device ID is kind of pointless on Wayland, so it might be better to
stick to something that works for both backends. Passing the device here
allows the higher layers to pick.

As per commit f71151a5 we focus an input window if no take-focus-window accepts
it. This might lead to an infinite loop if there are various focusable but
non-input windows in the stack.
When the current focus window is unmanaging and we're trying to focus a
WM_TAKE_FOCUS window, we intent to give the focus to the first focusable input
window in the stack.
However, if an application (such as the Java ones) only uses non-input
WM_TAKE_FOCUS windows, are not requesting these ones to get the focus. This
might lead to a state where no window is focused, or a wrong one is.
So, instead of only focus the first eventually input window available, try to
request to all the take-focus windows that are in the stack between the
destroyed one and the first input one to acquire the input focus.
Use a queue to keep track of those windows, that is passed around stealing
ownership, while we protect for unmanaged queued windows.
Also, reduce the default timeout value, as the previous one might lead to an
excessive long wait.
Added metatests verifying these situations.

As per commit f71151a5 we were ignoring WM_TAKE_FOCUS-only windows as focus
targets, however this might end-up in an infinite loop if there are multiple

take-focus one (that might not reply to the request).
Added a stacking test to verify this.

Since 4cae9b5b11, and indirectly before that as well, the
MetaMonitorManager::power-save-mode-changed is emitted even

As per commit 040de396b, we don't try to grab when shortcuts are inhibited,
However, this uses the focus window assuming that it is always set, while this
might not be the case in some scenarios (like when unsetting the focus before
requesting take-focus-window to acquire the input).
So allow the button grab even if the focus window is not set for the display
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/663https://gitlab.gnome.org/GNOME/mutter/merge_requests/668
On Wayland, if a client issues a inhibit-shortcut request, the Wayland
compositor will disable its own shortcuts.
We should also disable the default handler for the button grab modifier
so that button events with the window grab modifiers pressed are not
caught by the compositor but are forwarded to the client surface.
That also fixes the same issue with Xwayland applications issuing grabs,
as those end up being emulated like shortcut inhibition.

gnome-shell hardcodes a vertical one-column workspace layout, and

The way code was structured made it easy to misunderstand things as the
surface actor of a window actor could change over time. So is not the
case, however, the intention of the corresponding "update" function was
so that a surface actor could be assigned to a window actor as soon as
the X11 window was associated with its corresponding wl_surface, if the
window in question came from Xwayland.
Restructure the code and internal API a bit to make it clear that a
window actor only once gets a surface actor assigned to it, and that it
after that point never changes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/659
X11 actors need to release the server data (pixmap and damage) before the
display is closed.
During the close phase all the windows are unmanaged and this causes the window
actors to be removed from the compositor, unsetting their actor surface.
However, in case a window is animating the surface might not be destroyed until
the animation is completed and a reference to it kept around by gjs in the shell
case. By the way, per commit 7718e67f all window actors (even the animating
ones) are destroyed before the display is closed, but this is not true for the
child surface, because the parent window will just unref it, leaving it around
if reffed somewhere else. This is fine for wayland surfaces, but not for X11
ones which are bound to server-side pixmaps.
So, connect to the parent MetaWindowActor "destroy" signal, releasing the x11
resources that implies detaching the pixmap (unsetting the texture) and removing

free_damage and detach_pixmap functions are called inside dispose and an object
can be disposed multiple times, even when the display is already closed.
So, don't try to deference a possibly null-pointer, assigning the xdisplay too
early, as if the X11 related resources have been unset, the server might not be
open anymore. In fact, we assume that if we have a damage or a pixmap set,
the display is still open.

In MetaWindowActor creation we're setting the compositor private (i.e. the
window actor itself) of a window before creating the surface actor, and so
passing to the it a window without its compositor side set.
Since the surface actor might use the parent actor, set this before updating
the surface.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/660
As per commit 80e3c1d set_surface_actor has been added, meant to do different
things depending on the backend, like connecting to signals under X11.
However, the vfunc isn't ever used, making the X11 surfaces not to react to
repaint-scheduled signal.

Everytime the top window changes we connect/disconnect to the actor's destroy
signal, although as explained in commit ba8f5a11 this might be slower in case
the window actor has many other signal connections.
So, just track this using an ID.

There were fallbacks in place in case IN_FORMATS didn't yield any usable
formats: the formats in the drmModePlane struct, and a hard coded array.
The lack of these fallbacks in place could result in a segfault as code
using the supported plane formats assumed there were at least something
in there.

The display name is being used by the monitor manager to expose to name
to the DBUS API.
It is being rebuilt each time, so instead build the displa yname once
for the monitor and keep it around, with an API to retrieve it, so that
we can reuse it in preparation of xdg-output v2 support.

Simplify the call site a bit and make the native renderer know it should
queue mode reset itself when views have been rebuilt. This is done
partly due to more things needing to be dealt with after views have been
rebuilt.

window-actor: Turn into a derivable class
made the previous instance struct a instance private struct, but didn't
remove the parent field. Since it's unused, there is no point in keeping
it around, so lets drop it.

When building without EGL device support, the following compiler warning
is seen:
```
src/backends/native/meta-renderer-native.c:2637:20: warning: unused
variable ‘cogl_renderer_egl’ [-Wunused-variable]
```
Fix the warning by placing the relevant variable declarations within the
`#ifdef HAVE_EGL_DEVICE/#endif` statement.

We used to have wayland-specific paths for this in src/wayland, now we
have ClutterKeymap that we can rely on in order to do state tracking,
and can do this all on src/backend domain.
This accomodates the feature in common code, so will work on both
Wayland and X11.
