This was wrongly introduced in 75cffd0ec4. As the comment above explains, we
only want to queue redraws in response to surface/buffer damage.
This triggered a full redraw when using DMA buffers on Wayland as we currently
create a new texture on every buffer_attach(), breaking partial invalidation.

There might be some inconsistent event for which we don't have a known
source device.
In the current state we don't handle them and we could crash when getting
the current device tool.
So, add an utility function that retrieves the source device for an event
that warns if no device is found, and use this for Motion, Key and Button
events.
In case we don't have a valid source in such case, just return early instead
of trying to generate invalid clutter events.

Add an assert that we don't have a MetaWindow::monitor pointer that
points to an old MetaLogicalMonitor. After this, and the other
monitors-changed callbacks have been called, the old MetaLogicalMonitor
will be destoryed, thus if we didn't update the pointer here, we'll
point to freed memory, and will eventually crash later on.

This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

On wl_data_source destruction we used to indirectly unset the DnD selection
owner via the wl_resource destructor triggering the destruction of the
MetaWaylandDataSource, which would be caught through the weak ref set by
the MetaWaylandDragGrab.
This works as long as the grab is held, however we have a window between
the button being released and the drop site replying with
wl_data_offer.finish that the MetaWaylandDataSource is alive, but its
destruction wouldn't result in the call chain above to unsetting the DnD
source.
In other selection sources, we let the MetaWaylandDataDevice hold the
"ownership" of the MetaWaylandDataSource, and its weak ref functions unset
the respective MetaSelection owners. Do the same here, so the
MetaWaylandDataSource destruction is listened for all its lifetime.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591
This is wrong for both clipboard and DnD, as the selection source
will still be able to focus another surface, and churn another
wl_offer.
We should just detach the data offer from the data source in this
case, and let the source live on. However, we should still check
that there is a source and an offer to finish DnD, do that when
handling the drop operation instead.
https://gitlab.gnome.org/GNOME/mutter/issues/591
Those were used to signal clipboard ownership around, but that got
replaced by MetaSelection and friends. These signals are no longer
listened on, so can be safely removed.

ClutterTexture is going to be removed, so remove interactive tests that

We currently assume that the actor_animate() helper function returns
a timeline. However Clutter may skip implicit animations and simple
set properties directly, for example when the actor is hidden.
The returned timeline will be NULL in that case, and we abort when

Fix this by only setting up a completed handler when we are actually
animating, and complete the effect directly otherwise.

The actor is already in surface coordinate space, so we should not scale

Java applications might use override-redirect windows as parent windows for
top-level windows, although this is not following the standard [1].
In such case, the first non-override-redirect child window that is created
was marked as being on_all_workspaces since the call to
should_be_on_all_workspaces() returns TRUE for its parent, and this even
though the on_all_workspaces_requested bit is unset.
When a further child of this window was added, it was set as not having a
workspace and not being on_all_workspaces, since the call to
should_be_on_all_workspaces() for its parent would return FALSE (unless if
it is in a different monitor, and the multiple-monitors workspaces are
disabled).
Since per commit 09bab98b we don't recompute the workspace if the
on_all_workspaces bit is unset, we could end up in a case where a window can
be nor in all the workspaces or in a specific workspace.
So let's just ignore the transient_for bit for a window if that points to an
override-redirect, using the x11 root window instead.
Add a stacking test to verify this scenario (was failing before of this
commit).

Once we set the transient_for, we look for parent MetaWindow, so instead

Override-redirect windows have no workspace by default, and can't be parent
of a top-level window, so we must check that the parent window is not an

We're expected by MetaWaylandSurface to always pick the frame callbacks
out from the pending state when committing (applying) so that no frame
callbacks are unaccounted for. We failed to do this if our actor for
some reason (e.g. associated window was unmanaged) was destroyed. To
handle this situation better, store away the frame callbacks until we
some later point in time need to pass them on forward.

We ask XLib the next request serial number before performing other actions
triggered by meta_x11_display_set_input_focus_internal() that doesn't use

window as that's the operation that needs it.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/909
When using DesktopIcons extension and clicking in an icon, gnome-shell
starts an infinite loop caused by the first focus change that may trigger
on X11 a focus in/out event that leads to stage activation/deactivation
which never ends.
This happens because as part of meta_x11_display_set_input_focus_xwindow()
to focus the X11 stage window, we unset the display focus, but this also
causes to request the X11 display to unset the focus since we convolute by
calling meta_x11_display_set_input_focus() with no window, that leads to
focusing the no_focus_window and then a focus-in / focus-out dance that the
shell amplifies in order to give back the focus to the stage.
In order to fix this, mimic what meta_display_set_input_focus() does, but
without updating the X11 display, and so without implicitly calling
meta_x11_display_set_input_focus(), stopping the said convolution and
properly focusing the requested xwindow.
Also ensure that we're not doing this when using an older timestamp, since
this check isn't performed anymore.

`meta_surface_actor_is_obscured` implies that the actor got successfully culled

This is a workaround for X11 games which use randr to change the resolution
in combination with NET_WM_STATE_FULLSCREEN when going fullscreen.
Newer versions of Xwayland support the randr part of this by supporting randr
resolution change emulation in combination with using WPviewport to scale the
app's window (at the emulated resolution) to fill the entire monitor.
Apps using randr in combination with NET_WM_STATE_FULLSCREEN expect the
fullscreen window to have the size of the emulated randr resolution since
when running on regular Xorg the resolution will actually be changed and
after that going fullscreen through NET_WM_STATE_FULLSCREEN will size
the window to be equal to the new resolution.
We need to emulate this behavior for these games to work correctly.
Xwayland's emulated resolution is a per X11 client setting and Xwayland
will set a special _XWAYLAND_RANDR_EMU_MONITOR_RECTS property on the
toplevel windows of a client (and only those of that client), which has
changed the (emulated) resolution through a randr call.
This commit checks for that property and if it is set adjusts the fullscreen
monitor rect for this window to match the emulated resolution.
Here is a step-by-step of such an app going fullscreen:
1. App changes monitor resolution with randr.
2. Xwayland sets the _XWAYLAND_RANDR_EMU_MONITOR_RECTS property on all the
apps current and future windows. This property contains the origin of the
monitor for which the emulated resolution is set and the emulated
resolution.
3. App sets _NET_WM_FULLSCREEN.
4. We check the property and adjust the app's fullscreen size to match
the emulated resolution.
5. Xwayland sees a Window at monitor origin fully covering the emulated
monitor resolution. Xwayland sets a viewport making the emulated
resolution sized window cover the full actual monitor resolution.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/739
Add an adjust_fullscreen_monitor_rect virtual method to MetaWindowClass
and call this from setup_constraint_info() if the window is fullscreen.
This allows MetaWindowClass to adjust the monitor-rectangle used to size
the window when going fullscreen, which will be used in further commits
for a workaround related to fullscreen games under Xwayland.

This allows xdg_popup.grab() to work with styli. Without this check

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/886
When a touch sequence was rejected, the emulated pointer events would be
replayed with old timestamps. This caused issues with grabs as they
would be ignored due to being too old. This was mitigated by making sure
device event timestamps never travelled back in time by tampering with
any event that had a timestamp seemingly in the past.
This failed when the most recent timestamp that had been received were
much older than the timestamp of the new event. This could for example
happen when a session was left not interacted with for 40+ days or so;
when interacted with again, as any new timestamp would according to
XSERVER_TIME_IS_BEFORE() still be in the past compared to the "most
recent" one. The effect is that we'd always use the `latest_evtime` for
all new device events without ever updating it.
The end result of this was that passive grabs would become active when
interacted with, but would then newer be released, as the timestamps to
XIAllowEvents() would out of date, resulting in the desktop effectively
freezing, as the Shell would have an active pointer grab.
To avoid the situation where we get stuck with an old `latest_evtime`
timestamp, limit the tampering with device event timestamp to 1) only
pointer events, and 2) only during the replay sequence. The second part
is implemented by sending an asynchronous message via the X server after
rejecting a touch sequence, only potentially tampering with the device
event timestamps until the reply. This should avoid the stuck timestamp
as in those situations, we'll always have a relatively up to date
`latest_evtime` meaning XSERVER_TIME_IS_BEFORE() will not get confused.

This way, we can simply pop up the Looking Glass and run:
>>> Meta.add_clutter_debug_flags(Clutter.DebugFlag.PICK, 0, 0)
And measure specific actions or events on GNOME Shell.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/862
In a similar vein to commit 8fd55fef85. This notably failed when setting
the focus on the stage (eg. to redirect key events to Clutter actors).
Deeper in MetaDisplay focus updating machinery, it would check
meta_stage_is_focused() which would still return FALSE at the time it's
called.
This would not typically have side effects, but our "App does not respond"
dialogs see the focus change under their feet, so they try to bring
themselves to focus again. This results in a feedback loop.
Changing the order results in later checks on the X11 POV of the focus
being correct, so focus is not mistakenly stolen from the close dialog,
and it actually succeeds in keeping the key focus.

It might be the case that handling an event induces the stream to
trigger completion, hence removing itself from the list. In that
case we would operate on the no longer valid list element to fetch
the next one.
Keep a pointer to the next element beforehand, so we can tiptoe
over streams that did remove themselves.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/869
The streams were only detached from MetaX11Display (and its event handling)
on completion. This is too much to expect, and those might be in some
circumstances replaced while operating.
Make those streams detach themselves on dispose(), so we don't trip into
freed memory later on when trying to dispatch unrelated X11 selection events.

As the first step into removing Cogl types that are covered by
Graphene, remove CoglEuler and replace it by graphene_euler_t.
This is a mostly straightforward replacement, except that the
naming conventions changed a bit. Cogl uses "heading" for the
Y axis, "pitch" for the X axis, and "roll" for the Z axis, and
graphene uses the axis themselves. That means the 1st and 2nd
arguments need to be swapped.
Also adapt the matrix stack to store a graphene_euler_t in the
rotation node -- that simplifies the code a bit as well.

Requesting a selection with a NULL data source means "unset the clipboard",
but internally we use an unset clipboard as the indication that the
clipboard manager should take over.
Moreover, this unset request may go unheard if the current owner is someone
else than the MetaWaylandDataDevice.
Instead, set a dummy data source with no mimetypes nor data, this both
prevents the clipboard manager from taking over and ensures the selection
is replaced with it.
The MetaSelectionSourceMemory was also added some checks to allow for this
dummy mode.

If we did a mode set, the gamma may have been changed by the kernel, and
if we didn't also update the gamma in the same transaction, we have no
way to predict the current gamma ramp state. In this case, read the
gamma state directly from KMS.
This should be relatively harmless regarding the race conditions the
state prediction was meant to solve, as the worst case is we get none or
out of date gamma ramps; and since this is for when gamma ramps are not
updated at mode setting time, we'd get intermediate gamma state to begin
with, so it's not worse than what we currently do anyway.

For the most part, a MetaWindow is expected to live roughly as long as
the associated wl_surface, give or take asynchronous API discrepancies.
The exception to this rule is handling of reparenting when decorating or
undecorating a window, when a MetaWindow on X11 is made to survive the
unmap/map cycle. The fact that this didn't hold on Wayland caused
various issues, such as a feedback loop where the X11 window kept being
remapped. By making the MetaWindow lifetime for Xwayland windows being
the same as they are on plain X11, we remove the different semantics
here, which seem to lower the risk of hitting the race condition causing
the feedback loop mentioned above.
What this commit do is separate MetaWindow lifetime handling between
native Wayland windows and Xwayland windows. Wayland windows are handled
just as they were, i.e. unmanaged together as part of the wl_surface
destruction; while during the Xwayland wl_surface destruction, the
MetaWindow <-> MetaWaylandSurface association is simply broken.

Dropping the grab has the side effect that the pointer will be re-picked,
and it might find another surface with a pointer constraint. If that were

that might enable another pointer constraint.

We can't just update the state of the connector and CRTC from KMS since

changes by looking inside the MetaKmsUpdate object, and let the hot-plug
state changes happen after the actual hot-plug event.

Instead of storing the result of meta_prop_get_latin1_string() into
a temporary string value, g_strdup-ing that temp value storing the
g_strdup result into window->sm_client_id and then g_free-ing the
temporary string, we can pass window->sm_client_id as the place where
meta_prop_get_latin1_string() stores its result, since the result
from meta_prop_get_latin1_string() is itself a g_strdup-ed string,
so there is no need to g_strdup it again.
Note this drops the check to only issue the
"Window %s sets SM_CLIENT_ID on itself ..." warning once. This check is
not necessary as update_sm_hints() is only called once at window
creation time and is never called again.

Use g_strdup instead of malloc + strcpy, this also gets rid of a bunch
of error checking which is no longer necessary, also adjust the free
path accordingly.
Note that there was a malloc + XFree mismatch in the removed error-handling.

latin1_string_from_results and utf8_string_from_results use g_strndup,
so the returned string should be freed with g_free, rather then with
free or XFree. This fixes all free-s of buffers returned by these 2
functions to properly use g_free.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/786
Use g_new0 instead of calloc for motif_hints_from_results and adjust
its callers to use g_free.
Note that in the process_request_frame_extents function this replaces
the wrong original mismatch of calloc + XFree with a matching g_malloc +
g_free pair.

Clutter actors might emit property changes in dispose, while unparenting.
However we assume that the ::destroy signal is the last one we emit for an
actor, and that starting from this moment the object is not valid anymore,
and so we don't expect any signal emission from it.
To avoid this, freeze the object notifications on an actor during its
disposition, just before the ::destroy signal emission.
Update the actor-destroy test to verify this behavior.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/769
Clutter actors unset their parent on dispose, after emitting the ::destroy
signal, however this could cause ::parent-set signal emission. Since we
assume that after the destruction has been completed the actor isn't valid
anymore, and that during the destroy phase we do all the signal / source
disconnections, this might create unwanted behaviors, as in the signal
callbacks we always assume that the actor isn't in disposed yet.
To avoid this, don't emit ::parent-set signal if the actor is being
destroyed.
Update the actor-destroy test to verify this behavior.

Mutter issues a synchronous grab on the pointer for unfocused client
windows to be able to catch the button events first and raise/focus
client windows accordingly.
When there is a synchronous grab in effect, all events are queued until
the grabbing client releases the event queue as it processes the events.
Mutter does release the events in its event handler function but does so
only if it is able to find the window matching the event. If the window
is a shell widget, that matching may fail and therefore Mutter will not
release the events, hence causing a freeze in pointer events delivery.
To avoid the issue, make sure we sync the pointer events in case we
can't find a matching window.

It was not the lack of forcing the shadow fb that caused slowness, but
rather due to the method the shadow fb content was copied onto the
scanout fb. With 'clutter: Use cogl_blit_framebuffer() for shadow FB'
we'll use a path that shouldn't be slow when copying onto the scanout
fb.
Also 437f6b3d59 accidentally enabled
shadow fb when using hw accelerated contexts, due to the cap being set
to 1 in majority of drivers. While the kernel documentation for the
related field says "hint to userspace to prefer shadow-fb rendering",
the name of the hint when exposed to userspace is
DRM_CAP_DUMB_PREFER_SHADOW, thus should only be taken into consideration
for dumb buffers, not rendering in general.
This reverts commit 437f6b3d59.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/818
The commit 'renderer/native: Use shadow fb on software GL if preferred'
attempted to force using a shadow fb when using llvmpipe in order to
speed up blending, but instead only did so when llvmpipe AND the drm
device explicityl asked for it.
Now instead always force it for llvmpipe and other software rendering
backends, and otherwise just query the drm device (i.e.
DRM_CAP_DUMB_PREFER_SHADOW).

Since the recent clutter-content work, legacy scaling (in contrast
to the new stage-view-scaling) only applies to surfaces that belong
to a window. This broke scaling of DnD surfaces.
As a workaround, apply the same scaling on DnD-surface-actors until
we use stage-view-scaling by default and can remove this again.
Also: small corrections of geometry calculation
