Flushing the X11 selection output stream may happen synchronously or
implicitly, in which case there is not a task to complete. Check there
is actually a task before returning errors. We additionally set the
pipe_error flag, so future operations will fail with an error, albeit
with a more generic message.

(cherry picked from commit 1909977a67)
If a write_async() comes up while we are flushing on the background,
the task will be queued, but not deemed a reason on itself to keep
flushing (and finish the task) after a property delete event.
To fix this, do not ever queue up write_async tasks (this leaves
priv->pending_task only used for flush(), so the "flush to end"
behavior in the background is consistent). We only start a
background flush if there's reasons to do it, but the tasks are
immediately finished.
All data will still be ensured to be transfered on flush/close,
this makes the caller in this situation still able to reach to it.

(cherry picked from commit 655a783891)
It does not make sense to check for the stream not being closed,
this might happen multiple times during the lifetime of the stream
for a single transfer. We want to notify the INCR transfer just
once.
Check for the explicit conditions that we want, that the remaining
data is bigger than we can transfer at once, and that we are not
yet within the INCR transfer.

The stream automatically flushes after data size exceeds the
size we deem for INCR chunks, but we still try to copy it all.
Actually limit the data we copy, and leave the rest for future
INCR chunks.

(cherry picked from commit 7015bb3efd)
INCR transfers are mandated to finish with a final 0-size XChangeProperty
roundtrip after the final data chunk. Actually honor this and ensure we
iterate just once more for this.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1198
(cherry picked from commit 04d429b743)
This seemed to work under the assumption that a flush() call can
only result in one INCR roundtrip. This is evidently not true, so
we should hold things off until all pending data is actually flushed.

(cherry picked from commit 8a2b82897d)
If say we want 32bit data, but have 2 bytes stored, we would simply
ignore flush requests. Allow (and don't clear) the needs_flush flag
if we have less than the element size accumulated.
Instead handle this in can_flush(), so it's triggered whenever we
have enough data to fill 1 element, or if the stream is closing
(seems a broken situation, but triggered by the caller).

(cherry picked from commit 967966cdee)
XMaxRequestSize/XMaxExtendedRequestSize are documented to return
the maximum size in 4-byte units, whereas we are comparing this
to byte lenghts. We can afford 4x the data here.
Since I don't know the payload size of the XChangeProperty request,
be generous and allot 400 bytes for it, we have some to spare.

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 error was just logged but not raised. Do as the code comment said
and raise a pipe error at that moment, and for subsequent operations
on the output stream (although none besides close() should be expected
after propagating the error properly).

Support for them appears to be way less common than e.g. png, which is
currently the preferred format from Firefox, Chromium, Libreoffice and others.
Adopt to that fact.
As a side effect, this works around a bug observed when copying images in
Firefox on Wayland.

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.

(cherry picked from commit 8abdf16a39)
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.

Backported from 4cc29cfb61.
By default clutter will show an actor as it is added to a parent. This
means that after we create the window actor, when it's added to the
window group, we implicitly show it. What we really want is to not show
it until the window is supposed to be shown, which happens when
meta_window_actor_show() is called, as showing prior to that, could
cause issues.
Avoid the implicit show by setting the "show-on-set-parent" property on
the window actor to `FALSE` on window actor construction.

When an X11 window requests an initial workspace, we currently trust
it that the workspace actually exists. However dynamic workspaces
make this easy to get wrong for applications: They make it likely
for the number of workspaces to change between application starts,
and if the app blindly applies its saved state on startup, it will
trigger an assertion.
Make sure that we pass valid parameters to set_workspace_state(),
and simply let the workspace assignment fall through to the default
handling otherwise.

The actors of Wayland subsurfaces are set to be reactive on creation,
when receiving the `wl_subcompositor.get_subsurface` request.
However, if a client creates several subsurfaces and then creates the
xdg_toplevel object after, the previous subsurface actors are reset.
As a result, Clutter picking will skip and ignore those actors in
`clutter_actor_should_pick_paint()` because they aren't marked as
reactive anymore.
An example of such a client being affected by this issue is SCTK, the
Rust library implementing client side decorations for Wayland used
internally by winit and alacritty.
Move the `set_reactive()` call from `get_subsurface()` to the subsurface
`sync_actor_subsurface_state()` vfunc to make sure those remain reactive
even after `xdg_surface.get_toplevel` is invoked.

Most usually, applications either expose clipboard content either as text
or as images, so the prioritization here is pointless. However there's some
outliers like LibreOffice Calc which exports content as both image and text
formats (besides other internal ones).
In that mixed case, we probably prefer to keep text formats, rather than
image based ones.

Some ClutterOffscreenEffect subclasses, such as ClutterBrightnessContrastEffect,
early-return FALSE in pre-paint before chaining up. It's an important optimization
that avoids creating or updating the offscreen framebuffer.
However, if an offscreen framebuffer already exists by the time pre-paint fails,
it will be used *without* repaint the actor over it. That causes an old picture
of the actor to be displayed.
Fix that by always clearing the offscreen framebuffer when pre-paint fails.

When changing the 'enabled' property and disabling the offscreen effect,
it doesn't make sense to preserve the offscreen framebuffer. It's not
drawing, after all.
Furthermore, because ClutterOffscreenEffect only checks if the offscreen
framebuffer exists to decide whether or not to redraw, keeping the fbo
alive is a waste of resources.
Clear the offscreen framebuffer when the effect is disabled or enabled.

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

Say you're using intel gen3, you poor soul. Your big-GL maxes out at 1.5
unless you use dirty tricks, but you do have GLES2. We try to fall back
to GLES in this case, but we only ever say eglBindAPI(EGL_OPENGL_API).
So when we go to do CreateContext, even though we think we've requested
GLES 2.0, the driver will compare that "2.0" against the maximum big-GL
version, and things will fail.
Fix this by binding EGL_OPENGL_ES_API before trying a GLES context.

In XDND, we just get a hint on XdndPosition about what's the action
chosen by the user. Make the data source actions the full set on
XdndEnter (as we can't know better), and pass the hint in XdndPosition

Makes Wayland drop sites aware of the user action as per XDND with X11
drag sources, and still makes modifiers during DnD work.

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.
