This is done through gtk-shell ATM. If a window requests focus with
an invalid startup ID, just the demands-attention flag will be set.
The "did user interaction happen in between" checks are left to
meta_window_activate_full/meta_window_focus, by passing the timestamp
of the original launch request.
This version has 2 new requests:
- gtk_shell1.notify_launch notifies the compositor that the requesting
client shall launch another application. The given ID is expected to
be unique.
- gtk_surface1.request_focus notifies the compositor that a surface
requests focus due to it being activated. The given ID is passed to
this process through undetermined means, if it corresponds with a
current startup ID and there was no user interaction in between the
surface will be focused, otherwise it will demand attention.
Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

As with the commits earlier, this also adds const qualifiers where
expected. However, the const variables are casted to non-const variants
so they can be passed to glib functions that take non-const variants but
expect const-like input.
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.

When destructing a xdg_toplevel, we'll disassociate the actor from the
MetaWaylandSurface, to allow it to animate out. After having done this,
avoid trying to set it as unreactive when unsetting the window.
This fixes the runtime warning:
clutter_actor_set_reactive: assertion 'CLUTTER_IS_ACTOR (actor)' failed
Before processing the buffer damage region, intersect it with the buffer
rectangle to avoid trying to damage content outside the surface.
This fixes the runtime warning "GL error (1281): Invalid value"
happening when a client posts too large buffer damage larger.
This adds the required bits to wayland surfaces and ties them up
to the compositor parts.
The central part here is to recalculate the surface size accordingly
and to translate surface damage into buffer damage.
The choosen approach additionally lays groundwork for wp_viewporter
support, which is closely related in its nature.
A further explanation of buffer transforms from the specification:
> The purpose of this request is to allow clients to render content
> according to the output transform, thus permitting the compositor
> to use certain optimizations even if the display is rotated.
> Using hardware overlays and scanning out a client buffer for
> fullscreen surfaces are examples of such optimizations.
Commit 70036429bd mixed drag_origin and drag_surface, leading to warnings
and invisible drag icon. Fix this up so we correctly set up the feedback
actor. This will correctly display the DnD icon alongside the pointer.
It is meant to hold surfaces that require a ClutterActor, just like wl/xdg
shell surfaces and subsurfaces. Make it inherit from MetaWaylandActorSurface
so it gets that for free.
The type declaration is also made completely private, in order to avoid
cyclic dependency between meta-wayland-surface.h and
meta-wayland-actor-surface.h. We just require the GType fro assign_role()
anyway.
As with the Wayland display name, to avoid clashes with already an
running Xwayland or Xorg instance, override the X11 display name to
something less likely to cause a clash.

For Wayland outputs, we do not expose the actual transformation because
mutter does not support wl_surface.set_buffer_transform yet, instead we
swap the logical width and height when the output is rotated.
However, a client wishing to use the physical size would get confused,
so if the output is rotated, rotate the physical dimensions as well for
consistency.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/369
It relied on indices in arrays determining tile direction and
non-obvious bitmask logic to translate to _GTK_EDGE_CONSTRAINTS. Change
this to explicitly named edge constraints, and clear translation methods
that converts between mutters and GTK+s edge constraint formats.
The touch handling code uses evdev API, thus will not work on other
backends. Thus, put touch handling code behind runtime backend checks
and only include the code when native backend support is enabled.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
We might unset focus, or already be out of focus (e.g. an X11 client or
clutter text entry is focused) when a text-input state is committed by
the client. We handled this before, except when text input was
explicitly disabled by the client, the Wayland text-input was in focus
by the input method, and it focused itself out.
Simplify the logic a bit by just dropping the state on the floor in all
cases where after any potential focus changes were done, we are not
focused.

When repicking after a surface was destroyed, if the destroyed surface
was the drag focus, we'd try to focus-out from it after it was
destroyed, causing a NULL pointer dereference.

To avoid a known race condition in the wl_output protocol documented in
https://phabricator.freedesktop.org/T7722, mutter delays the `wl_output`
destruction but nullify the `logical_monitor` associated with the
`wl_output` and the binding routine `bind_output()` makes sure not to
send wl_output events if the `logical_monitor` is `NULL` (see commit
1923db97).
The binding routine for `xdg_output` however does not check for such a
condition, hence if the output configuration changes while a client is
binding to xdg-output (typically Xwayland at startup), mutter would
crash while trying to access the `logical_monitor` which was nullified
by the change in configuration.
Just like `bind_output()` does for wl_output, do not send xdg-output
events if there is no `logical_monitor` yet.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/194
When we update the main monitor, there is a rule that makes it so that
popup windows use the same main monitor as their parent. In the commit
f4d07caa38 the call that updates and
fetches the main monitor of the toplevel accidentally changed to update
from itself, causing a indefinite recursion eventually resulting in a
crash.

As with xdg-toplevel, a gtk-surface can be unmanaged by the compositor
without the client knowing about it, meaning the client may still send
updates and make requests. Handle this gracefully by ignoring them. The
client needs to reset all the state anyway, if it wants to remap the
same surface.
https://gitlab.gnome.org/GNOME/mutter/issues/240
As with xdg-toplevel proper, a legacy xdg-toplevel can be unmanaged by
the compositor without the client knowing about it, meaning the client
may still send updates and make requests. Handle this gracefully by
ignoring them. The client needs to reassign the surface the legacy
xdg-toplevel role again, if it wants to remap the same surface, meaning
all state would be reset anyway.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/240
A toplevel window can be unmanaged without the client knowing it (e.g. a
modal dialog being unmapped together with its parent. When this has
happened, take frame callbacks queued on a commit and cache them on the
generic surface queue. If the toplevel is to be remapped because the
surface was reassigned the toplevel role, the cached frame callbacks
will be queued on the surface actor and dispatched accordingly.
https://gitlab.gnome.org/GNOME/mutter/issues/240
A window can be unmanaged without asking the client to do it, for
example as a side effect of a parent window being unmanaged, if the
child window was a attached dialog.
This means that the client might still make requests post updates to it
after that it was unmapped. Handle this gracefully by NULL-checking the
surface's MetaWindow pointer. We're not loosing any state due to this,
as if the client wants to map the same surface again, it needs to either
reassign it the toplevel role, or reset the xdg-toplevel, both resulting
in all state being lost anyway.

A toplevel window can be unmanaged without the client knowing it (e.g. a
modal dialog being unmapped together with its parent. When this has
happened, take frame callbacks queued on a commit and cache them on the
generic surface queue. If the toplevel is to be remapped, either because
the surface was reassigned the toplevel role, or if it was reset and
remapped, the cached frame callbacks will be queued on the surface actor
and dispatched accordingly.
https://gitlab.gnome.org/GNOME/mutter/issues/240
A popup can be reset, and when that happens, window and actor are
destroyed, and won't be created again unless it is reassigned the
popup role.
If a client queued frame callbacks when resetting a popup, the frame
callbacks would be left in the pending state, as they were not queued on
the actor, meaning we'd hit an assert about the frame callbacks not
being handled. Fix this by caching them on the MetaWaylandSurface, so
that they either are cleaned up on destruction, or queued on the actor
would the surface be re-assigned the popup role.
https://gitlab.gnome.org/GNOME/mutter/issues/240
Sometimes it may be useful for roles to put callbacks in the generic
surface frame callback queue. The surface frame callback queue will
either eventually be processed on the next surface role assignment that
places the frame callbacks in a role specific queue, processed at some
other point in time by a role, or cleaned up on surface destruction.
