Just as with painting, add a pick context that carries pick related
temporary state when doing actor picking. It is currently unused, and
will at least at first still carry around a framebuffer to deal track
view transforms etc.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/935
When painting, actors rely on semi global state tracked by the state to
get various things needed for painting, such as the current draw
framebuffer. Having state hidden in such ways can be very deceiving as
it's hard to follow changes spread out, and adding more and more state
that should be tracked during a paint gets annoying as they will not
change in isolation but one by one in their own places. To do this
better, introduce a paint context that is passed along in paint calls
that contains the necessary state needed during painting.
The paint context implements a framebuffer stack just as Cogl works,
which is currently needed for offscreen rendering used by clutter.
The same context is passed around for paint nodes, contents and effects
as well.
In this commit, the context is only introduced, but not used. It aims to
replace the Cogl framebuffer stack, and will allow actors to know what
view it is currently painted on.

It's not always clear how the dma-buf functions work (e.g. where memory
is allocated) without actually going in-depth in the code. This just
adds a few commments to more quickly gain understanding.

Checking the leds is not really accurate, since some devices have mode
switch buttons without leds. Check in the button flags whether they are
mode switch buttons for any of ring/ring2/strip/strip2, and return the
appropriate group.

While most of the code to compute a window's layer isn't explicitly
windowing backend specific, it is in practice: On wayland there are
no DESKTOP windows(*), docks(*) or groups.
Reflect that by introducing a calculate_layer() vfunc that computes
(and sets) a window's layer.
(*) they shall burn in hell, amen!
https://gitlab.gnome.org/GNOME/mutter/merge_requests/949
Most of the layer computation that the stack does actually depends
on the windowing backend, so we will move it to a vfunc.
However before we do that, split out the bit that will be shared.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/949
When a window that should be stacked above another one is placed in a lower
layer than the other window, we currently allow promoting it to the higher
layer when it has a "transient type". We should do the same when the window
is an actual transient of the other window.
This is particularly relevant for wayland windows, where types play a
much smaller role: Transient windows like non-modal dialogs (and since
commit 666bef7a, popup windows as well) currently end up underneath their
always-on-top parent.
https://gitlab.gnome.org/GNOME/mutter/issues/587
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.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/947
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
stand in the way for that. Some test texture features, while some makes
heavy use of ClutterTexture to implement their testing. Remove these
tests to prepare for the removal of ClutterTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/932
ClutterTexture is deprecated, lets remove the trivial usage with a
simple gdk-pixbuf using constructor putting pixel contents into a
ClutterImage then putting said image in a plain ClutterActor.
Tested partially, as the interactive tests cannot be properly run at the
moment.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/932
As was with the tests run via meson test, for the interactive tests we
too need to configure the mutter backend and initialize things in order
to be able to run any tests.

Properly take the panel_orientation_transform into account in
update_monitor_crtc_cursor. This fixes us sometimes drawing the cursor
on two monitors at the same time as we did not properly swap the crtc
width/height when a panel_orientation_transform is active.

It seems that sometimes these functions are called by Javascript in
GNOME Shell during tear down. This causes segfaults and crash reports,
but without any backtraces other than the entry and exit points into
gjs.
In order to get more useful information about where these calls come
from, validate the input passed gracefully, by complaining in the log
and returning NULL values.

Add missing clutter_x11_[un]trap_x_errors around the XIGetProperty call
in meta-input-settings-x11.c's get_property helper function.
This fixes mutter crashing with the following error if the XInput device
goes away at an unconvenient time:
X Error of failed request: XI_BadDevice (invalid Device parameter)
Major opcode of failed request: 131 (XInputExtension)
Minor opcode of failed request: 59 ()

Serial number of failed request: 454
Current serial number in output stream: 454

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
using it as instance parameter to g_signal_connect().
Fix this by only setting up a completed handler when we are actually
animating, and complete the effect directly otherwise.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/925
The actor is already in surface coordinate space, so we should not scale
with the buffer scale to transform surface coordinates to stage
coordinates.
This bug causes input method using wayland text-input protocol to
receive wrong cursor location. Reproduced in ibus (when candidate
window is open) with scaling factor other than 1.
This commit also fixes pointer confinement.

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
of overwriting this value for loops check, just use another function
and avoid to look for the xwindow again when setting the MetaWindow parent.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/895
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
O-R one when setting the workspace state.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/895
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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/893
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
the request serial anyways. So, just request it before updating the focus
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.

This function is already checking for the focus surface client
matching the requestor. The type check was slightly bogus though
as it'd be an screwup in our code, make it an assert instead.
Also, move the check for the client having the focus into the
upper call, so this and wl_data_device.set_selection code can
get more in line.

We have an abstract MetaWaylandDataSource and 2 subclasses for
clipboard/primary data sources. Since the abstraction provided
by the additional sublevel is arguable, push the wl_resource
field up, and leave us with just 2 objects to think about, all
of them containing a wl_resource.
