Try to bypass compositing if there is a fullscreen toplevel window with
a buffer compatible with the primary plane of the monitor it is
fullscreen on. Only non-mirrored is currently supported; as well as
fullscreened on a single monitor. It should be possible to extend with
more cases, but this starts small.
It does this by introducing a new MetaCompositor sub type
MetaCompositorNative specific to the native backend, which derives from
MetaCompositorServer, containing functionality only relevant for when
running on top of the native backend.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
We need to coordinate with MetaCompositor during pre-paint so that we
have control over whether MetaLater callbacks happen first, or the
MetaCompositor pre-paint logic.
In order to do so, make MetaLater listen to a new signal "pre-paint" on
MetaCompositor, that is called MetaCompositors own pre-paint handling.
This fixes an issue where the top window actor was calculated after the
MetaCompositor pre-paint handling, meaning the top actor being painted
was out-of-date.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
Since the order of destruction during MetaDisplay tear down is a bit
unordered, there are pieces that try to destruct its compositing
dependent pieces (i.e. queued MetaLater callbacks) after MetaCompositor
has been cleaned up, meaning we need to put some slightly awkward NULL
checks to avoid crashing.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
MetaCompositor is the place in mutter that manages the higher level
state of compositing, such as handling what happens before and after
paint. In order for other units that depend on having a compositor
instance active, but should be initialized before the X11 implementation
of MetaCompositor registers as a X11 compositing manager, split the
initialization of compositing into two steps:
1) Instantiate the object - only construct the instance, making it
possible for users to start listening to signals etc
2) Manage - this e.g. establishes the compositor as the X11 compositing
manager and similar things.
This will enable us to put compositing dependent scattered global
variables into a MetaCompositor owned object.
For now, compositor management is internally done by calling a new
`meta_compositor_do_manage()`, as right now we can't change the API of
`meta_compositor_manage()` as it is public. For the next version, manual
management of compositing will removed from the public API, and only
managed internally.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
While at it, fix some style inconsistencies, for now use a single
singleton struct instead of multiple static variables, and
other non-functional cleanups. Semantically, there is no changes
introduced.

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
While this is fairly incomplete, as to check things fully we need to use
TEST_ONLY in atomic to try out a complete assignment on the device, but
this works well enough for legacy non-modifier cases.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
Instead of always swapping buffers and flipping the back buffer, make it
possible to scan out a provided buffer directly without swapping any EGL
buffers.
A buffer is passed as an object implementing the empty CoglScanout
interface. It is only possible to do this in the native backend; and the
interface is implemented by MetaDrmBufferGbm. When directly scanned out,
instead of calling gbm_surface_lock_front_buffer() to get the gbm_bo and
fbid, get it directly from the MetaDrmBufferGbm, and use that to create
the page flip KMS update.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
Better to have the relevant object figure out whether it is a good
position to be unredirectable other than the actor, which should be
responsible for being composited.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
This removes the MetaWindowX11::priv pointer. It is replaced with a
meta_window_x11_get_private() helper function, and another method to get
the client rect without going through MetaWindowX11Private.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
Surface buffers are created with meta_drm_buffer_new_acquire(), taking a
gbm_surface acquiring the gbm itself, and meta_drm_buffer_new_take()
that takes over ownership of a passed gbm_bo.
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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
The CRTC level transform (not necessarily the hw transform) must be
taken into account when calculating the position of the CRTC in the
stage coordinate space, when placing the hw cursor, otherwise we'll
place the cursor as if the monitor was not rotated.
This wasn't a problem in the past, as with rotation, we always used the
OpenGL cursor, so the issue newer showed.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1199
The port to per CRTC views was incomplete; we still used the logical
monitor layout as the stage view layout, while still using one view per
CRTC.
This worked fine for most cases, e.g. regular monitors, tiled or
non-tiled, transformed or non-transformed. Where it broke, however, was
when a monitor consists of multiple CRTCs. We already have the layout a
CRTC corresponds to on the stage kept with the CRTC metadata, so use
this directly.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1170https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1199`
The CRTC level transform (i.e. not necessarily the one set on the
hardware) is what is relevant for calculating the layout the CRTC will
have on the stage, so only use the one that can be handled by the
hardware for the CRTC assignment.
This makes the CRTC layout valid for tiled monitors.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1199
Previously the tile coordinate was used to offset a CRTC scanout
coordinate within a larger framebuffer. Since 3.36 we're always
scanning out from (0, 0) as we always have one framebuffer per CRTC; we
instead use the tile coordinate to calculate the coordinate the tile has
in the stage view. Adapt calculation to fulfil this promise instead of
the old one.
This also corrects the tiled custom monitor test case.

test_client_new might return early if conditions are not met, leaving some

Most visible with xwayland-on-demand, at the time of setting things up
for X11 selections, we don't forward the current state. This makes the
first started X11 app oblivious to eg. the current clipboard.
Syncing selections up at the time of initializing the X11 selection
stuff ensures that doesn't happen.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1186
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.

At some point we crossed the streams... In a short timespan we had
1f00aba92c merged, pushing WacomDevice to a common parent object,

Currently we check whether a window is alive everytime it's focused.
This means that an application that doesn't respond to the check-alive
event during startup always showing the "application froze" dialog,
without the user ever trying to interact with it.
An example where this tends to to happen is with games, and for this
particular scenario, it's purely an annoyance, as I never tried to
interact with the game window in the first place, so I don't care that
it's not responding - it's loading.
To avoid these unnecessary particular "app-is-frozen" popups, remove the
alive check from the focus function, and instead move it back to the
"meta_window_activate_full()" call. To also trigger it slightly more
often, also add it to the path that triggers the window focus when a
user actively clicks on the window.
This means that we currently check whether a window is alive on:
* Any time the window is activated. This means e.g. alt-tab or
selecting the window in the overview.
* The user clicks on the window.
Note that the second only works for an already focused window on
Wayland, as on X11, we don't refocus it. This particular case isn't
changed with this commit, as we didn't call meta_window_focus() to begin
with here.

This fixes an issue where a non-maximized screen casted window would be

Picking now only happens on allocated actors, but the
callback in the actor-pick test is not waiting for the
stage to run an allocation cycle. Ideally, we'd wait
for this cycle, but for now, forcing an allocation works
as well.
Allocate the overlay actor in the actor-pick test.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1169
Normally we bail out in `sync_actor_geometry()`. The comment there
states:
```
Normally we want freezing a window to also freeze its position; this allows
windows to atomically move and resize together, either under app control,
or because the user is resizing from the left/top. But on initial placement
we need to assign a position, since immediately after the window
is shown, the map effect will go into effect and prevent further geometry
updates.
```
The signal for the initial sync originates in `MetaWindow` though and predates
`xdg_toplevel_set_maximized`, which again calls `meta_window_force_placement`,
triggering the signal too early. As a result, Wayland clients that start up
maximized have a wrong map animation, starting in the top-left corner.
In order to fix this without changing big parts of the geometry logic and risking
regressions, force the initial sync again before mapping.
Solution suggested by Jonas Ådahl.

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().

GObject recommends to break references to other objects on dispose
instead of finalize, also we want to release the pressed virtual buttons
as early as possible if we know the object is getting destroyed.
So release the pressed buttons and unref our virtual
MetaInputDeviceNative when the dispose vfunc is called, which also
allows us to release the buttons immediately from javascript instead of
waiting for the garbage collector by calling run_dispose() on the
object.

This allows us to screencast any window continuously, even
without it being visible. Because it's still being painted,
clients continue to receive frame callbacks, and people
are happy again.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1129
Just like what's done for monitor screencasting. Unfortunately, there's
no mechanism to share fences with PipeWire clients yet, which forces
us to guarantee that a frame is completed after blitting.

MetaScreenCastWindowStreamSrc connects to the "damaged" signal of
MetaWindowActor. This signal is not exactly tied to the paint cycle
of the stage, and a damage may take quite a while to arrive when
a client doesn't want to draw anything. For that reason, the window
screencast can start empty, waiting for a damage to arrive.
Ensure at least one frame is recorded when enabling the window stream.

cogl_framebuffer_push_rectangle_clip() acts on the current modelview

When calculating the transform we should apply to the cursor sprite
before uploading it to the cursor plane, we must also take into
account non upright mounted LCD panels.
Otherwise the cursor ends up 90 degrees rotated on devices where the
LCD panel is mounted 90 degrees rotated in its enclosure.

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.

The transactional KMS API has been modelled after atomic KMS. Atomic KMS
currently doesn't support forwarding cursor hotspot metadata, thus it
was left out of the transactional KMS API having the user set the simply
create a plane assigment with the cursor sprite assigned to a cursor
plane using regular coordinates.
This, however, proved to be inadequate for virtual machines using
"seamless mouse mode" where they rely on the cursor position to
correspond to the actual cursor position of the virtual machine, not the
cursor plane. In effect, this caused cursor positions to look "shifted".
Fix this by adding back the hotspot metadata, right now as a optional
field to the plane assignment. In the legacy KMS implementation, this is
translated into drmModeSetCursor2() just as before, while still falling
back to drmModeSetCursor() with the plane coordinates, if either there
was no hotspot set, or if drmModeSetCursor2() failed.
Eventually, the atomic KMS API will learn about hotspots, but when
adding our own atomic KMS backend to the transacitonal KMS API, we must
until then still fall back to legacy KMS for virtual machines.

When calculating the resource scale of a clone source, we might end up
in situations where we fail to do so, even though we're in a paint. A
real world example when this may happen if this happens:
* A client creates a toplevel window
* A client creates a modal dialog for said toplevel window
* Said client commits a buffer to the modal before the toplevel
If GNOME Shell is in overview mode, the window group is hidden, and the
toplevel window actor is hidden. When the clone tries to paint, it fails
to calculate the resource scale, as the parent of the parent (window
group) is not currently mapped. It would have succeeded if only the
clone source was unmapped, as it deals with the unmapped actor painting
by setting intermediate state while painting, but this does not work
when the *parent* of the source is unmapped as well.
Fix this by inheriting the unmapped clone paint even when calculating
the resource scale.
This also adds a test case that mimics the sequence of events otherwise
triggered by a client. We can't add a Wayland client to test this, where
we actually crash is in the offscreen redirect effect used by the window
dimming feature in GNOME Shell.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/808https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1147
For HiDPI pointer cursors backed by Wayland surfaces, the hotspot must
be placed using integers on the logical pixel grid. In practice what
this means is that if the client loads a cursor sprite with the buffer
scale 2, and it's hotspot is not dividable by 2, it will be rounded
down to an integer that can. E.g. a wl_surface with buffer scale 2 and a
cursor image with hotspot coordinate (7, 7) will have the coordinate
(3.5, 3.5) in surface coordinate space, and will in practice be rounded
down to (3, 3) as the hotspot position in wl_pointer only takes
integers.
To not potentially shift by 1 pixel on HiDPI monitors when switching
between wl_surface backend cursor sprites and built-in ones, make the
built in one emulate the restrictions put up by the Wayland protocol.
This also initializes the theme scale of the xcursor sprite instances to
1, as they may not have been set prior to being used, it'll only happen
in response to "prepare-at" signals being emitted prior to rendering.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/1092https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1107
We checked that the content size was appropriately painted in the stage,
but didn't take into account that the size of the sampled texture
region, meaning that when stage views were scaled, we'd think that we
would draw a texture scaled, as e.g. a 200x200 sized texture with buffer
scale 2 would have the size 100x100. When stage views were not scaled,
we'd apply a geometry scale meaning it'd end up as 200x200 anyway, thus
pass the check, but when stage views are scaled, it'd still be painted
as a 100x100 shaped texture on the stage, thus failing the
are-we-unscaled test.
Fix this by comparing the transformed paint size with the sampled size,
instead of the paint size again, when checking whether we are being
painted scaled or not. For example, when stage views are scaled, our
200x200 buffer with buffer scale 2, thus content size 100x100 will
transform to a 200x200 paint command, thus passing the test. For
non-scaled stage views, our 200x200 buffer with buffer scale 2 thus
content size 100x100 will also transform into a 200x200 paint command,
and will also pass the check, as the texture sample region is still
200x200.

A user may have configured an output to be panning, e.g. using xrandr
--output <output> --mode <mode> --panning <size>. Respect this by making
the logical monitor use the panning size, instead of the mode. This
makes e.g. makes the background cover the whole panning size, and panels
etc will cover the whole top of the panned area, instead of just the top
left part covering the monitor if having panned to (0, 0).

The upper layers (OSDs basically) want to know the monitor that a
tablet is currently assigned to, not the monitor just as configured
through settings.
This broke proper OSD positioning for display-attached tablets since
commit 87858a4e01, as the MetaInputMapper kicks in precisely when
there is no configured monitor for the given device.
Consulting both about the assigned output will make OSDs pop up
again in the right place.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/971
We used to inhibit all pad actions while the OSD is shown, but one we
would actually want to handle are mode switches while the OSD is open.
So it has an opportunity to catch up to the mode switch.
This lets MetaInputSettings reflect the mode switch (eg. when querying
action labels), so the OSD has an opportunity to update the current
actions.

Commit cda9579034 fixed a corner case when setting the initial workspace
state of transient windows, but it still missed a case:
should_be_on_all_workspaces() returns whether the window should be on all
workspaces according to its properties/placement, but it doesn't take
transient relations into account.
That means in case of nested transients, we can still fail the assert:
1. on-all-workspaces toplevel
2. should_be_on_all_workspaces() is TRUE for the first transient's parent,
as the window from (1) has on_all_workspaces_requested == TRUE
3. should_be_on_all_workspaces() is FALSE for the second transient's
parent, as the window from (2) is only on-all-workspace because
of its parent
We can fix this by either using the state from the root ancestor
instead of the direct transient parent, or by using the parent's
on_all_workspaces_state.
The latter is simpler, so go with that.

This class sits between ClutterInputDevice and the backend implementations,
it will be the despositary of features we need across both backends, but
don't need to offer through Clutter's API.
As a first thing to have there, add a getter for a WacomDevice. This is
something scattered across and somewhat inconsistent (eg. different places
of the code create wacom devices for different device types). Just make it

Most people just see a harmless warning when applying this setting to
all touchpads (which this patch fixes). But tap[-and-drag] is supposed

wacom devices. This happens on a per-device basis, so the warning is
gone too.

This fixes a case that was overlooked in
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1036 - when we
have a geometry scale > 1 and Wayland subsurfaces that have an offset
to their parent surface (which is often the case when the toplevel surface
includes decoration/shadows etc.), we have to add extra offset to their
opaque regions so they match their 'visible' location.
This is necessary as `meta_cullable_cull_out_children` moves the coordinate
system during culling, but does not know about geometry scale.
Also, remove the redundant check for `window_actor` - we only hit this code
path if a `window_actor` culls out its children.

Some tablets like the Cintiq 24HDT have several mode switch buttons
per group. Those are meant to jump straight to a given mode, however
we just handle cycling across modes (as most other tablets have a
single mode switch button per group).
So spice up the mode switch handling so we handle multiple mode
switch buttons, assigning each of them a mode. If the device only
has one mode switch button, we do the old-fashioned cycling.

When a page flip fails with a certain error code, we've treated this as
a hint that page flipping is broken and we should try to use mode
setting instead.
On some drivers, it seems that this error is also reported when there
was no mode set, which means we'll have no cached mode set to use in the
fallback. The lack of prior mode set tends to happen when we hit a race
when the DRM objects change before we have the time to process a hotplug
event.
Handle the lack a missing mode set in the flip fallback path, with the
assumption that we'll get a hotplug event that'll fix things up for us
eventually.

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.

We therefore fall back to software / gl cursor.
The check for that currently happens after we tried to upload the cursor image
to the hardware plane though.
This is made worse by the fact that in the scaling step, where we scale the
cursor image to the desired size, until now we expected a valid common scale -
otherwise scaling the image by an uninitialized float.
Make sure we bail out early during the scale/upload step if we don't have common
scales and transforms - to avoid that bug and save some unnecessary work.

Make sure it is only the special modifier (hardcoded to 1 currently)
which is being pressed (not counting locked modifiers) before notifying
that the special modifier is pressed, as we are interested in it being
pressed alone and not in combination with other modifier keys.
This helps in two ways:
- Pressing alt, then ctrl, then releasing both won't trigger the locate
pointer action.
- Pressing alt, then ctrl, then down/up to switch workspace won't interpret
the last up/down keypress as an additional key on top of the special ctrl
modifier, thus won't be forwarded down to the focused client in the last
second.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/812https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1014
If you first press a key that triggers the "special modifier key" paths
(ctrl, super), and then press another key that doesn't match (yet?) any
keybindings (eg. ctrl+alt, super+x), the second key press goes twice
through process_event(), once in the processing of this so far special
combination and another while we let the event through.
In order to keep things consistent, handle it differently depending on
whether we are a wayland compositor or not. For X11, consider the event
handled after the call to process_event() in process_special_modifier_key().
For Wayland, as XIAllowEvents is not the mechanism that allows clients see
the key event, we can just fall through the regular paths, without this
special handling.

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.

To keep consistent and avoid confusion, rename the function:
`meta_window_x11_buffer_rect_to_frame_rect()`
to:
`meta_window_x11_surface_rect_to_frame_rect()`
As this function doesn't deal with the `window->buffer_rect` at all.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1091
The code in `build_and_scan_frame_mask` predates the introduction of the
`MetaShapedTexture` API to get the texture width hand height.
Use the new `meta_shaped_texture_get_width/height` API instead of using
the CoGL paint texture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1091
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.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/1007https://gitlab.gnome.org/GNOME/mutter/merge_requests/1091
For X11 clients running on Xwayland, the opaque, input and shape regions
are processed from different properties and may occur at a different
time, before the actual buffer is eventually committed by Xwayland.
Add a new API `update_regions` to window actor to trigger the update of
those regions when needed.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1091
Commit 7dbb4bc3 cached the client area when the client was frozen.
This is not sufficient though, because the buffer size might still be
lagging waiting for the buffer from Xwayland to be committed.
So instead of caching the client size from the expected size, deduce the
client area rectangle from the surface size, like we did for the frame
bounds in commit 1ce933e2.
This partly reverts commit 7dbb4bc3 - "window-actor/x11: Cache the
client area"

Listen for GPU hotplug events to initialize their cursor support.
This fixes one reason for why DisplayLink devices may not be using a hardware
cursor. Particularly, when a DisplayLink device is hotplugged for the first
time such that EVDI creates a new DRM device node after gnome-shell has already
started, we used to forget to initialize the cursor support.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1097
Extract the code to initialize a single GPU cursor support into its own
function. The new function will be used by GPU hotplug in the future.
This is a pure refactoring without any behavioral changes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1097
For every stream src, we created and attached a GSource. Upon stream
src destruction, we g_source_destroy():ed the GSource. What
g_source_destroy() does, hawever, is not really "destroy" it but only
detaches it from the main context removing the reference the context had
added for it via g_source_attach(). This caused the GSource to leak,
although in a detached state, as the reference taken on creation was
still held.
Fix this by also removing our own reference to it when finalizing.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1106
PipeWire will be unable to dequeue a buffer if all are already busy.
This can happen for valid reasons, e.g. the stream consumer not being
fast enough, so don't complain in the journal if it happens.

While we will always have cursor planes, as we'll currently create fake
ones when real ones are missing (See #1058), eventually we will run into
situations where we can't create fake ones, for example for atomic KMS
drivers that don't advertise any cursor planes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1079
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.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/1098https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1110
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.

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
A placement rule is always about placing a window relative to its
parent. In order to eventually place it against predicted future parent
positions, make the placement rule processing output relative
coordinates, having the caller deal with turning them into absolute.

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 made a signal, so the upper layers (read: gnome-shell) may
decide what services to spawn. The signal argument contains a task
that will resume MetaX11Display startup after it is returned upon.

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.

This shape region culling was wrongly implemented in f5a28aa9, as it
does not take frame offsets into account, and is also redundant, as
we already set the opaque region of the underlying surface accordingly.
The other parts were implemented in ac7aa114, the reason given in
the commit message:
```
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.
```
is wrong though - culling on X11 actors works just fine and did only
not work in Wayland sessions because of a bug that got fixed in
19814497.
In conclusion the whole part appears to be redundand and some testing
done suggests the same. Drop it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1082
If a opaque region is explicitly set we should not consider the surface
opaque, as that implies e.g. a shape region is set.
If no opque region is set but the texture does not have an alpha channel,
we can savely cull it out.

We want sysprof's exact datadir for compatability with
platforms where software is installed into their own
individual immutable prefix's. Such that, mutter's prefix will
never equate to sysprof's. This depends on a MR in sysprof [0]
which adds datadir to its pkgconfig files, as these files will always
have the proper path we want.
This adds version a constraint on sysprof_dep, as datadir was added to
the .pc in this version.

Given that on Wayland we are pretty much guaranteed to finish MetaX11Display
setup after the MetaCompositor is enabled, we may drop the
meta_compositor_manage() x11 initialization bits, and move them into the
MetaX11Compositor subclass where it's actually needed.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
We artificially made Xwayland initialization synchronous, as we used
to rely on MetaX11Display and other bits during meta_display_open().
With support for Xwayland on demand and --no-x11, this is certainly
not the case.
So drop the main loop surrounding Xwayland initialization, and turn
it into an async operation called from meta_display_init_x11(). This
function is turned then into the high-level entry point that will
get you from no X server to having a MetaX11Display.
The role of meta_init() in Xwayland initialization is thus reduced
to setting up the sockets. Notably no processes are spawned from here,
deferring that till there is a MetaDisplay to poke.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
This ATM completes the task right away, but we will want to do
further things here that are asynchronous in nature, so prepare
for this operation being async.
Since the X11 backend doesn't really need this, make it go on
the fast lane and open the MetaX11Display right away, the case
of mandatory Xwayland on a wayland session is now handled
separately.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
With Xwayland initialization going async, these errors will seep
into the parts controlled by g_test*(), resulting in the harmless
errors about DBus names not acquired turned fatal.
Set an error log handler, and specifically ignore those.

It might not be available right on initialization time if X11 is started
asynchronously. As this is a requirement for our tests, ensure it is there
before proceeding with the test.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/944
This used to be set on meta_compositor_manage(), but only if there is a
MetaX11Display. Given meta_display_init_x11() is Wayland only, and we can
always assume compositing to be enabled, just have it invariably set after
the X server is up.

Even though cogl_framebuffer_flush() was supposed to be enough,
it ends up creating streams with odd visual glitches that look
very much like unfinished frames.
Switch back to cogl_framebuffer_finish(), which is admittedly
an overkill, but it's what works for now. There is anedoctal
evidence showing it doesn't incur in worse performance.

Much like monitor streaming, implement window streaming by
making the window actor draw itself with a paint context
that used the passed framebuffer.
Now that all MetaScreenCastStreamSrc subclasses implement
blit_to_framebuffer, remove the conditional check from
meta_screen_cast_stream_src_blit_to_framebuffer().

Implement PipeWire's add_buffer and remove buffer, try and export
a DMA buffer first and, on failure, fallback to memfd.
When DMA buffers are successfully created and shared, blit the
framebuffer contents when drawing instead of downloading the pixels.

Create a new gbm_bo using the same given geometry, and export the new
bo's DMA buffer fd. The new bo lives as long as necessary to be used,
and reused, by PipeWire.
Unfortunately, PipeWire doesn't support modifiers properly, so use the
linear format for now. For now, a hardcoded format of DRM_FORMAT_XRGB8888
is set, so we don't need to negotiate the format with PipeWire early.

If the cursor sprite does not match the scale factor or transformation
of the monintor, we currently fall back to a software cursor, causing
redraws of the shell. This commit implements scaling and transforming
of the cursor sprite, so we can use it with hardware planes, too.
This commit does the following steps:
1. Make sure we reupload the cursor image if the cursor is over
a logical monitor not matching the scale or transform from the previous
update.
2. Before upload to the hardware plane, scale and transform the cursor
image if possible and necessary.
3. Make sure we always use the hardware cursor if possible (only fall
back to software/OGL cursor if it is visible on multiple logical monitors
with differet scales/transforms).
4. Transform or scale the cursor coordinates if necessary.
