Since we're now connecting to one more signal of MetaWaylandOutput, keep
signal connections in one place and move connecting the
"output-destroyed" signal to surface_entered_output() and disconnecting
it to surface_left_output().
This also allows us to use the "outputs_to_destroy_notify_id" as a
simple set and rename it to "outputs".
While at it, also use g_hash_table_destroy() instead of
g_hash_table_unref() since destroy is more clear than unref and does the
same thing in this case.

When hotplugging a new monitor, we recreate all the MetaWaylandOutputs
and need to emit leave events to the surfaces for the old wl_outputs and
enter events for the newly created ones.
There's a race condition though: We might update the monitors a surface
is on (and thus emit enter/leave events for the wl_outputs) before the
Wayland client is registered with the new wl_output (ie. the
bind_output() callback of MetaWaylandOutput was called), which means we
don't send an enter event to the client in surface_entered_output().
Since MetaWaylandSurface now has the MetaWaylandOutput in its outputs
hashtable, it thinks the client has been notified and won't send any
more enter events.
To fix that, make MetaWaylandOutput emit a new signal "output-bound"
when a client bound to the output and make all surfaces which are on
that output listen to the signal. In the signal handler compare the
newly added client to the client the surface belongs to, and if it's the
same one, send an enter event to that client.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1230
The "output-destroyed" signal is used for notifying MetaWaylandSurfaces
that an output they are shown just got invalid (for example because a
monitor hotplug happened).
While we delay the destroying of outputs by 10 seconds since commit
1923db97 because of a race-condition, it doesn't make sense to wait 10
seconds until we let surfaces know that an output was destroyed.
So move the emission of the "output-destroyed" signal to
make_output_inert(), which is called before we start the 10 seconds
delay.

Instead of having everything clumped at MetaWaylandDataManager,
split the primary selection to its own struct. This manager is
handled separately from wl_data_device_manager and other selection
managers, so they would be able to interoperate between them, even.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
This is still an openly defined struct, as we will need accessed
by "subclasses". Same principle applies than with the
MetaWaylandDataSource refactor, this is not meant to introduce
functional changes, so just go with it.
On the bright side, the interactions are now clearer, so it could
be made saner in the future.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
The split wasn't 100% clean, and some extra private API had to be
added for it (but well, looking at the API, it's already evident
there's a cleanup/streamlining task due). This is meant to be a
refactor with no functional changes, so just go with it.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
We already have a signal callback that translates selection ownership changes to
data_device/primary .selection events. Given both will be run when a data source
is being replaced, and this event emission being deleted is kinda short sighted
in that in only knows about Wayland, rely entirely on MetaSelection::owner-changed
emission.
Fixes spurious .selection(null) events being sent when a compositor-local source
takes over the selection without the focus changing (eg. screenshot to clipboard).

We are meant to send a .cancelled event after the drop is performed
in certain situations, but only for version>3 clients. Since this is
all version 3 business, only set the drop_performed flag for v3
clients. This drops the need to perform version checks at the time
of cancelling (which is present for other usecases in v1).
Fixes emission of wl_data_source.cancelled for v1 clients.

This will check whether the current backing buffer is compatible with
the primary plane of the passed CoglOnscreen. Since this will extend the
time before a buffer is released, the MetaWaylandBufferRef is swapped
and orphaned if a new buffer is committed before the previous one was
released. It'll eventually be released, usually by the next page flip
callback.
Currently implemented for EGLImage and DMA-BUF buffer types.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
Advertising support for modifiers means we will most likely not not be
able to scan out client buffers directly, meaning it just as likely that
we won't be able to scan out even fullscreen windows without atomic KMS.
When we have atomic support, we should advertise support for modifiers
if atomic is used to drive the CRTCs, as we by then can check whether we
can scan out directly, place in an overlay plane, etc.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
Currently a buffer use count always reaches zero before it is replaced.
This is due to the fact that at the point a new buffer is attached, the
last potential user releases it (the stage) since the currently
displayed frame has a composited copy of the buffer.
This may however change, if a buffer is scanned out directly, meaning it
should not be released until the page flip callback is invoked.
Prepare for this by making the buffer reference a heap allocated struct,
enabling us to keep a pointer to it longer than the buffer is attached.

On VT switch, the devices are removed, which means for Wayland disabling
the keyboard.
When the keyboard is disabled, the associated `xkb_state` is freed and
recreated whenever the keyboard is re-enabled when switching back to the
compositor VT.
That means the `xkb_state` for Wayland is lost whereas the same for
clutter is kept, which causes to a discrepancy with locked modifiers on
VT switch.
To avoid that issue, preserve the XKB info only to dispose it when the
keyboard is eventually finalized.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/344https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1185
IBusInputContext/ClutterInputFocus/GtkIMContext all go for offset+len
for their ::delete-surrounding signals, with offset being a signed int
(neg. to delete towards left of selection, pos. to delete towards right
of selection) and len being an unsigned int from the offset (and
presumably, skipping the current selection).
The text-input protocols however pass in this event two unsigned integers,
one being the length of text to delete towards the left of the selection,
and another the length of text to delete towards the right of the selection.
To translate properly these semantics, positive offsets shouldn't account
for before_length, and negative offset+len shouldn't account for after_length.
The offset/length approach may of course represent deletions that are
detached from the current cursor/selection, we simply delete the whole range
from the cursor/selection positions then.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/517
The input method can assign a negative value to
clutter_input_method_delete_surrounding() to move the cursor to the left.
But Wayland protocol accepts positive values in delete_surrounding() and
GTK converts the values to the negative ones in
text_input_delete_surrounding_text_apply().

When resizing a window interactively, we'll set a grab operation and a
grab window, among other things. If we're resizing (including setting
initial size, i.e. mapping) another window, that didn't change position,
don't use the gravity of the grab operation when resizing our own
window.
This fixes an issue with jumpy popup position when moving a previously
mapped gtk popover.

This is so that cogl-trace.h can start using things from cogl-macros.h,
and so that it doesn't leak cogl-config.h into the world, while exposing
it to e.g. gnome-shell so that it can make use of it as well. There is
no practical reason why we shouldn't just include cogl-trace.h via
cogl.h as we do with everything else.

Both IBus and ClutterInputFocus work in character offsets for the cursor
position in the preedit string. However the zwp_text_input protocol does
define the preedit string cursor offset to be in bytes.
Fixes client bugs in representing the caret within the preedit string,
as we were clearly giving the wrong offset.

We send configure events for state changes e.g. for `appears-focused`,
etc. What we don't want to do is to do this for popup windows, as in
Wayland don't care about this state.
When the focus mode was configured to "sloppy focus" we'd get
`appears-focused` state changes for the popup window only by moving the
mouse cursor around, and while a popup may care about focus, it does not
care about related appearance, as there is no such state in xdg_popup.
What these state changes instead resulted in was absolute window
configuration events, intended for toplevel (xdg_toplevel) windows. In
the end this caused the popup to be positioned aginst at (0, 0) of the
parent window, as the assumptions when the configuration of the popup
was acknowledged is that it had received a relative position window
configuration.
Fix this by simply ignoring any state changes of the window if it is a
popup, meaning we won't send any configuration events intended for
toplevels for state changes. Currently we don't have any way to know
this other than checking whether it has a placement rule. Cleaning up
MetaWindow creation is left to be dealt with another day.

There is a race where an output can be used as a fullscreen target, but
it has already been removed due to a hotplug. Handle this gracefully by
ignoring said output in such situations.

For X11 clients running on Wayland, the actual texture is set by
Xwayland.
The shape, input and opaque regions, however are driven by X11
properties meaning that those may come at a different time than the
actual update of the content.
This results in black areas being visible at times on resize with
Xwayland clients.
To make sure we update all the regions at the same time the buffer is
updated, update the shape, input and opaque regions when the texture is
committed from when the Xwayland surface state is synchronized.
That fixes the remaining black areas being sometimes visible when
resizing client-side decorations windows on Xwayland.

If we don't force the placement, we enter the constrain machinery with
the position (0, 0), meaning we always get the "current work area" setup
to correspond to whatever logical monitor was at that position.
Avoid this by doing the same as "meta_window_force_placement()" and set
"window->calc_placement" to TRUE while move-resizing, causing the
move-resize to first calculate the initial position.

This commit completes the implementation of `xdg_wm_base` version 3,
which introduces support for synchronized implicit and explicit popup
repositioning.
Explicit repositioning works by the client providing a new
`xdg_positioner` object via a new request `xdg_popup.reposition`. If the
repositioning is done in combination with the parent itself being
reconfigured, the to be committed state of the parent is provided by the
client via the `xdg_positioner` object, using
`xdg_positioner.set__parent_configure`.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
This sets the `is_reactive` flag on the window placement rules, causing
the popups to be reconfigured as they are affected by environmental
changes, such as the parent moving in a way making the popup partially
offscreen.
As with synchronization, the implementation is dormant, as the
version of the advertised global isn't bumped yet, as the new protocol
version is not yet fully implemented.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
This commits adds support on the MetaWindow and constraints engine side
for asynchronously repositioning a window with a placement rule, either
due to environmental changes (e.g. parent moved) or explicitly done so
via `meta_window_update_placement_rule()`.
This is so far unused, as placement rules where this functionality is
triggered are not yet constructed by the xdg-shell implementation, and
no users of `meta_window_update_placement_rule()` exists yet.
To summarize, it works by making it possible to produce placement rules
with the parent rectangle a window should be placed against, while
creating a pending configuration that is not applied until acknowledged
by the client using the xdg-shell configure/ack_configure mechanisms.
An "temporary" constrain result is added to deal with situations
where the client window *must* move immediately even though it has not yet
acknowledged a new configuration that was sent. This happens for example
when the parent window is moved, causing the popup window to change its
relative position e.g. because it ended up partially off-screen. In this
situation, the temporary position corresponds to the result of the
movement of the parent, while the pending (asynchronously configured)
position is the relative one given the new constraining result.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
MetaGravity is an enum, where the values match the X11 macros used for
gravity, with the exception that `ForgetGravity` was renamed
`META_GRAVITY_NONE` to have less of a obscure name.
The motivation for this is to rely less on libX11 data types and macros
in generic code.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
A placement rule placed window positions itself relative to its parent,
thus converting between relative coordinates to absolute coordinates,
then back to relative coordinates implies unwanted restrictions for
example when the absolute coordinate should not be calculated againts
the current parent window position.
Deal with this by keeping track of the relative position all the way
from the constraining engine to the move-resize window implementation.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
To organize things a bit better, put the fields related to the placement
rule state in its own anonymous struct inside MetaWindow. While at it,
rename the somewhat oddly named variable that in practice means the
current relative window position.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
After popup placement rules have gone through the constraints engine has
ended up resulting in an actual move, pass the window configuration down
the path using relative coordinates, as that is what the next layer
(xdg-shell implementation) actually cares about.
In the future, this will also be helpful when the configured position is
not against the current state of the parent.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
meta_window_wayland_finish_move_resize() inhibited window moves to be
finished if there was a resize grab active at the time, in order to
handle window resizing. Change this to only affect the grabbed window
itself, so that e.g. a popup can be positioned according to a pending
configuration while there is an active resize grab.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
This is used by GDK and the X11 bits, but may also be used for
other initialization services we might need to run along with
Xwayland initialization.
However, as the -initfd argument in Xwayland is a fairly new
feature, add some meson build-time checks so that the feature
is handled transparently while allowing to explicitly set/unset
it.
