When destroying a window that has a parent, we initially try to focus one of
its ancestors. However if no ancestor can be focused, then we should instead
focus the default focus window instead of trying to request focus for a window
that can't get focus anyways.

On FreeBSD, gethostname is guarded by '__POSIX_VISIBLE >= 200112', which
requires either '_POSIX_C_SOURCE >= 200112' or '_XOPEN_SOURCE >= 600'.
Defining _XOPEN_SOURCE to 500 does not break the build because of
implicit declaration, but it defeats the purpose of defining the macro.

We get a signed integer (-1 meaning "no workspace specified"), store it in
an unsigned integer, check for >= 0 (of course it is!) and set as the window
workspace (signed integer, -1 meaning "show on all workspaces"). What could
possibly go wrong?

This commit introduces, and makes use of, a transactional API used for
setting up KMS state, later to be applied, potentially atomically. From
an API point of view, so is always the case, but in the current
implementation, it still uses legacy drmMode* API to apply the state
non-atomically.
The API consists of various buliding blocks:
* MetaKmsUpdate - a set of configuration changes, the higher level
handle for handing over configuration to the impl backend. It's used to
set mode, assign framebuffers to planes, queue page flips and set
connector properties.
* MetaKmsPlaneAssignment - the assignment of a framebuffer to a plane.
Currently used to map a framebuffer to the primary plane of a CRTC. In
the legacy KMS implementation, the plane assignment is used to derive
the framebuffer used for mode setting and page flipping.
This also means various high level changes:
State, excluding configuring the cursor plane and creating/destroying
DRM framebuffer handles, are applied in the end of a clutter frame, in
one go. From an API point of view, this is done atomically, but as
mentioned, only the non-atomic implementation exists so far.
From MetaRendererNative's point of view, a page flip now initially
always succeeds; the handling of EBUSY errors are done asynchronously in
the MetaKmsImpl backend (still by retrying at refresh rate, but
postponing flip callbacks instead of manipulating the frame clock).
Handling of falling back to mode setting instead of page flipping is
notified after the fact by a more precise page flip feedback API.
EGLStream based page flipping relies on the impl backend not being
atomic, as the page flipping is done in the EGLStream backend (e.g.
nvidia driver). It uses a 'custom' page flip queueing method, keeping
the EGLStream logic inside meta-renderer-native.c.
Page flip handling is moved to meta-kms-impl-device.c from
meta-gpu-kms.c. It goes via an extra idle callback before reaching
meta-renderer-native.c to make sure callbacks are invoked outside of the
impl context.
While dummy power save page flipping is kept in meta-renderer-native.c, the
EBUSY handling is moved to meta-kms-impl-simple.c. Instead of freezing the
frame clock, actual page flip callbacks are postponed until all EBUSY retries
have either succeeded or failed due to some other error than EBUSY. This
effectively inhibits new frames to be drawn, meaning we won't stall waiting on
the file descriptor for pending page flips.

The MetaKmsImpl implementation may need to add a GSource that should be
invoked in the right context; e.g. a idle callback, timeout etc. It
cannot just add it itself, since it's the responsibility of MetaKms to
determine what is the impl context and what is the main context, so add
API to MetaKms to ensure the callback is invoked correctly.
It's the responsibility of the caller to eventually remove and destroy
the GSource.

As with CRTC state, variable connector state is now fetched via the
MetaKmsConnector. The existance of a connector state is equivalent of
the connector being connected. MetaOutputKms is changed to fetch
variable connector state via MetaKmsConnector intsead of KMS directly.
The drmModeConnector is still used for constructing the MetaOutputKms to
find properties used for applying configuration.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Move reading state into a struct for MetaCrtcKms to use instead of
querying KMS itself. The state is fetched in the impl context, but
consists of only simple data types, so is made accessible publicly. As
of this, MetaCrtcKms construction does not involve any manual KMS
interaction outside of the MetaKms abstraction.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
Represents drmModeConnector; both connected and disconnected. Currently
only provides non-changing meta data. MetaOutputKms is changed to use
MetaKmsConnector to get basic metadata, but variable metadata, those
changing depending on what is connected (e.g. physical dimension, EDID,
etc), are still manually retrieved by MetaOutputKms.

A plane is one of three possible: primary, overlay and cursor. Each
plane can have various properties, such as possible rotations, formats
etc. Each plane can also be used with a set of CRTCs.
A primary plane is the "backdrop" of a CRTC, i.e. the primary output for
the composited frame that covers the whole CRTC. In general, mutter
composites to a stage view frame onto a framebuffer that is then put on
the primary plane.
An overlay plane is a rectangular area that can be displayed on top of
the primary plane. Eventually it will be used to place non-fullscreen
surfaces, potentially avoiding stage redraws.
A cursor plane is a plane placed on top of all the other planes, usually
used to put the mouse cursor sprite.
Initially, we only fetch the rotation properties, and we so far
blacklist all rotations except ones that ends up with the same
dimensions as with no rotations. This is because non-180° rotations
doesn't work yet due to incorrect buffer modifiers. To make it possible
to use non-180° rotations, changes necessary include among other things
finding compatible modifiers using atomic modesetting. Until then,
simply blacklist the ones we know doesn't work.

Add MetaKmsCrtc to represent a CRTC on the associated device. Change
MetaCrtcKms to use the ones discovered by the KMS abstraction. It still
reads the resources handed over by MetaGpuKms, but eventually it will
use only MetaKmsCrtc.
MetaKmsCrtc is a type of object that is usable both from an impl task
and from outside. All the API exposed via the non-private header is
expected to be accessible from outside of the meta-kms namespace.
https://gitlab.gnome.org/GNOME/mutter/issues/548https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
The intention with KMS abstraction is to hide away accessing the drm
functions behind an API that allows us to have different kind of KMS
implementations, including legacy non-atomic and atomic. The intention
is also that the code interacting with the drm device should be able to
be run in a different thread than the main thread. This means that we
need to make sure that all drm*() API usage must only occur from within
tasks that eventually can be run in the dedicated thread.
The idea here is that MetaKms provides a outward facing API other places
of mutter can use (e.g. MetaGpuKms and friends), while MetaKmsImpl is
an internal implementation that only gets interacted with via "tasks"
posted via the MetaKms object. These tasks will in the future
potentially be run on the dedicated KMS thread. Initially, we don't
create any new threads.
Likewise, MetaKmsDevice is a outward facing representation of a KMS
device, while MetaKmsImplDevice is the corresponding implementation,
which only runs from within the MetaKmsImpl tasks.
This commit only moves opening and closing the device to this new API,
while leaking the fd outside of the impl enclosure, effectively making
the isolation for drm*() calls pointless. This, however, is necessary to
allow gradual porting of drm interaction, and eventually the file
descriptor in MetaGpuKms will be removed. For now, it's harmless, since
everything still run in the main thread.

MetaStageWatch, watch modes and the watch function are part
of the new stage view watching API. It's design does not
rely on signals on purpose; the number of signals that would

MetaStageWatch is an opaque structure outside of MetaStage.
This will be used by the screencast code to monitor a single

Currently the EGLDevice code gets the display and calls eglInitialize.
As a follow-up it checks the required EGL extensions - technically it
could check the EGL device extensions earlier.
In either case, eglTerminate is missing. Thus the connection to the
display was still bound.
This was highlighted with Mesa commit d6edccee8da ("egl: add
EGL_platform_device support") + amdgpu.
In that case, since the eglTerminate is missing, we end up reusing the
underlying amdgpu_device due to some caching in libdrm_amdgpu. The
latter in itself being a good solution since it allows buffer sharing
across primary and render node of the same device.
Note: we should really get this in branches all the way back to 3.30.

As per commit 7718e67f, destroying the compositor causes destroying window
actors and this leads to stack changes, but at this point the stack was already

has already been destroyed.
As consequence, also the stamps should be destroyed at later point.

To emulate X11 grabs, mutter as a Wayland compositor would disable its
own keyboard shortcuts and when the X11 window is an override redirect
window (which never receives focus), it also forces keyboard focus onto
that X11 O-R window so that all keyboard events are routed to the
window, just like an X11 server would.
But that's a bit of a “all-or-nothing” approach which prevents
applications that would legitimately grab the keyboard under X11 (like
virtual machine viewers) to work by default.
Change “xwayland-allow-grabs” to control whether the keyboard focus
should be locked onto override redirect windows in case of an X11 grab.
For stringent needs, careful users can still use the blacklisting
feature (i.e. a list containing “!*”) to prevent grabs from any X11
applications to affect other Wayland native applications.

We handle this in backend specific code for x11, so do the wayland
bits here. We can only honor this on applications that request focus
on a surface after a startup request, as we do need an explicit
surface to apply the workspace on (and we don't have additional clues
like WMCLASS on X11). Notably, gtk_shell1.notify_startup doesn't suffice.
Another gotcha is that the .request_focus happens when the surface is
already "mapped". Due to the way x11 and the GDK api currently work (first
reply on the startup id, then map a window, then request focus on that
window). This means the surface will ignore at this point
window->initial_workspace, so it must be actively changed.

On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.

This argument instructs Xwayland to exit when there are no further
client connections. However we eventually want to handle restarts
ourselves (where, notably, mutter's will be at least the last client
connection).
This behavior could also induce race conditions on startup with clients
that quickly open and close a display, which is a more pressing issue.
Also, add -noreset back (which was also removed in commit 054c25f693 that
added -terminate). We don't want to reset the X server to a pristine state

It is now separated into meta_xwayland_start(), which picks an unused
display and sets up the sockets, and meta_xwayland_init_xserver(), which

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

We use a GtkIconTheme (thus icon-theme, thus xsettings, thus x11) just to
grab a "missing icon" icon to show in place. Relax this requirement that

It seems better to have the callers (presumably UI layers) aware of this
and set a proper icon by themselves, but AFAICS there is none in sight,
not even plain mutter seems to use MetaWindow::[mini-]icon. Probably
worth a future cleanup.

We'd break the loop for moving attached windows at the first window,
meaning we'd only ever move a single attached dialogs or popup if it was
the first window in the list. This doesn't work out well when there are
multiple popups open, so don't break out of the loop at all until all
windows are potentially moved.
This fixes an issue in gtk4 where one or more non-grabbing popups would
end up unattached if there were more than one and the parent window was
moved.

XkbNewKeyboardNotify informs the client that there is a new keyboard
driving the VCK. It is essentially meant to notify that the keyboard
possibly has a different range of HW keycodes and/or a different
geometry.
But the translation of those keycodes remain the same, and we don't
do range checks or geometry checks (beyond using KEY_GRAVE as "key
under Esc", but that is hardly one). It seems we can avoid the
busywork that is releasing all our passive grabs, reloading the keymap
and regenerating the keycombos and restoring the passive grabs.

All child classes of `MetaWaylandShellSurface` as well as
`MetaWaylandSurfaceRoleXWayland` should only sync their actor if
their toplevel surface has a window. Currently this check is done
in the actor-surface class, but not all surface classes have a
toplevel window, e.g. dnd-surfaces.
Move the check to the right places.
For subsurfaces this assumes that the subsurface is not the child of
a window-less surface (like, as stated above, e.g. a dnd-surface).
If we want to support subsurfaces of window-less surfaces in the future
we have to extend the check here.
But as this is not a regression, ignore this case for now.

This is a simple clipboard manager implementation on top of MetaSelection.
It will inspect the clipboard content for UTF-8 text and image data whenever
any other selection source claims ownership, and claim it for itself
whenever the clipboard goes unowned.
The stored text has a maximum size of 4MB and images 200MB, to prevent the
compositor from allocating indefinite amounts of memory.
This is not quite a X11 clipboard manager, but also works there.

This object represents the selection ownership from an X11 client. The

MetaSelectionSource represents a primary/clipboard/dnd selection owner,
it is an abstract type so wayland/x11/etc implementations can be provided.
These 3 selections are managed by the MetaSelection object, the current
selection owners will be set there, and signals will be emitted so the
previous selection owner can clean itself up.
The actual data transfer is done through the meta_selection_transfer_async()
call, which will take a GOutputStream and create a corresponding
GInputStream from the MetaSelectionSource in order to splice them.

When the compositor is destroyed we should cleanup the list of window actors we
created and destroy them.
Since all the actors are added to the window_group or top_window_group we can
just destroy these containers (together with the feedback_group), and simply
free the windows list.
This is particularly needed under X11 because before we destroy the display, we
might do some cleanups as detaching the surface pixmaps and freeing the damages
and if this happens at later point (for example when triggered by garbage
collector in gnome-shell), we might crash because the x11 dpy reference is
already gone.
Destroying the window actors instead, ensures we avoid any further call to X11
related functions and that we release the actors XServer resources.

When an application stops responding, the shell darkens its windows.
If a window from a not-responding application gets unmanaged

When focus stealing prevention kicks in, mutter would set the demand
attention flag on the window.
Focus stealing prevention would also prevent the window from being
raised and focused, which is expected as its precisely its purpose.
Yet, when that occurs, the user expects the window which has just been
prevented from being focused to be the next one in the MRU list, so
that pressing [Alt]-[Tab] would raise and give focus to that window.
This works fine when the window is placed on the primary monitor, but
not when placed on another monitor, in which case the window which has
been denied focus is placed ahead of the MRU list and pressing
[Alt]-[Tab] would leave the focus on the current window.
This is because of a mechanism in `meta_display_get_tab_list()` which
forces the windows with the demand attention flag set to be placed first
in the MRU list when they're placed on a workspace different from the
current one.
But because workspaces apply only to the primary monitor (by default),
the windows placed on other outputs have their workspace set to `NULL`
which forces them ahead of the MRU list by mistake.
Fix this by using the appropriate `meta_window_located_on_workspace()
function to check if the window is on another workspace.

Since "renderer/native: make EGL initialization failure not fatal" it is
possible, under specific failure conditions, to end up with a primary GPU whose
EGL initialization failed. That cannot work.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/521
The failure to initialize EGL does not necessarily mean the KMS device cannot
be used. The device could still be used as a "secondary GPU" with the CPU copy
mode.
If meta_renderer_native_create_renderer_gpu_data () fails,
meta_renderer_native_get_gpu_data () will return NULL, which may cause crashes.
This patch removes most of the failures, but does not fix the NULL dereferences
that will still happen if creating gpu data fails.
This patch reorders create_renderer_gpu_data_gbm () so that it fails hard only
if GBM device cannot be created, and otherwise always returns an initialized
gpu data structure. Users of the gpu data structure are responsible for
checking egl_display validity.
The GBM device creation failure is a hard failure because presumably GBM is
necessary for cursors.

We're currently always waiting for unfinished page flips before flipping
again. This is awkward when we are in an asynchronous retry-page-flip
loop, as we can synchronously wait for any KMS page flip event.
To avoid ending up with such situations, just freeze the frame clock
while we're retrying, then thaw it when we succeded.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
We rely on the frame clock to compress input events, thus if the frame
clock stops, input events are not dispatched. At the same time, there
is no reason to redraw at a full frame rate, as nothing will be
presented anyway, so slow down to 10Hz (compared to the most common
60Hz). Note that we'll only actually reach 10Hz if there is an active
animation being displayed, which won't happen e.g. if there is a screen
shield in the way.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/506
When we're in a page-flip retry loop due to the FIFO being full
(drmModePageFlip() failing with EBUSY), we should not continue to try
when starting to power save, as that means we're blocking new frames,
which itself blocks input events due to them being compressed using the
frame clock.
We'd also hit an assert assuming we only try to page flip when not power
saving.
Thus, fake we flipped if we ended up reaching a power saving state while
retrying.

DPMS is configured from a bit all over the place: via D-Bus, via X11 and

Commit 8e9184b6 added filtering to avoid image jaggies when downscaling
but used `LINEAR_MIPMAP_NEAREST`. In some situations this could lead to
GL choosing a single lower resolution mipmap and then upscaling it, hence
slightly blurry.
We don't want to revert that change since it avoids aliasing jaggies, so
let's use `LINEAR_MIPMAP_LINEAR` instead. This provides the highest quality
filtering that GL can do and avoids the situation of GL using a single
mipmap that's lower resolution than the screen. Now it will blend that one
with the next mipmap which is higher resolution than the screen. This still
avoids jaggies but also maintains 1px resolution.
