Which is used for Wayland popup grabs.
The issue here is that we don't want the code that raises or focuses
windows based on mouse ops to run while a client has a grab.
We still keep the "old" grab infrastructure in place for now, but
ideally we'd replace it eventually with a better grab-op infrastructure.
Do to a bad mixup, the surface listener was never actually fired.
This was accidentally fixed as part of a refactoring in a27fb19,
but the surface listener was broken, and we started crashing. To
fix, just remove the surface listener, as we've mostly been testing
without it.
This is not needed since the instance is being destroyed and in fact
actively harmful when code called from other handlers disconnects us
for other reasons. In that case we might crash because the
disconnection doesn't prevent other handlers from running in the
current signal emission and thus we try to remove ourselves from an
empty list.
This changes the user data of all surface extensions resources to be
the MetaWaylandSurface instead of the MetaWaylandSurfaceExtension,
which means that we no longer need all these pesky wl_container_ofs
in implementations.
Don't set the surface actor to a new buffer if it's becoming unmapped.
This is also technically wrong since we'll send out the release event,
but oh well.
We should probably decouple MetaWaylandBuffer from the CoglTexture
at some point, so we can send out releases on-demand.
We need a MetaWaylandSurface to build a MetaSurfaceActor, but
we don't have one until we get the set_window_xid() call from
XWayland. On the other hand, plugins expect to see the window
actor right from when the window is created, so we need this
empty state.
Based on a patch by Jasper St. Pierre.
This time, to make way for MetaSurfaceActorEmpty. This also fixes
destroy effects as a side effect. It still has issues if we try
to re-assign an actor that's already toplevel (e.g. somebody
re-popping up a menu that's already being destroyed), but this
will be fixed soon.
The idea here is that MetaWindowActor will do the unparenting of
the surface actor when it itself is destroyed. To prevent bad issues
with picking, we only make the surface actor reactive when it's
toplevel.
The rendering logic before was somewhat complex. We had three independent
cases to take into account when doing rendering:
* X11 compositor. In this case, we're a traditional X11 compositor,
not a Wayland compositor. We use XCompositeNameWindowPixmap to get
the backing pixmap for the window, and deal with the COMPOSITE
extension messiness.
In this case, meta_is_wayland_compositor() is FALSE.
* Wayland clients. In this case, we're a Wayland compositor managing
Wayland surfaces. The rendering for this is fairly straightforward,
as Cogl handles most of the complexity with EGL and SHM buffers...
Wayland clients give us the input and opaque regions through
wl_surface.
In this case, meta_is_wayland_compositor() is TRUE and
priv->window->client_type == META_WINDOW_CLIENT_TYPE_WAYLAND.
* XWayland clients. In this case, we're a Wayland compositor, like
above, and XWayland hands us Wayland surfaces. XWayland handles
the COMPOSITE extension messiness for us, and hands us a buffer
like any other Wayland client. We have to fetch the input and
opaque regions from the X11 window ourselves.
In this case, meta_is_wayland_compositor() is TRUE and
priv->window->client_type == META_WINDOW_CLIENT_TYPE_X11.
We now split the rendering logic into two subclasses, which are:
* MetaSurfaceActorX11, which handles the X11 compositor case, in that
it uses XCompositeNameWindowPixmap to get the backing pixmap, and
deal with all the COMPOSITE extension messiness.
* MetaSurfaceActorWayland, which handles the Wayland compositor case
for both native Wayland clients and XWayland clients. XWayland handles
COMPOSITE for us, and handles pushing a surface over through the
xf86-video-wayland DDX.
Frame sync is still in MetaWindowActor, as it needs to work for both the
X11 compositor and XWayland client cases. When Wayland's video display
protocol lands, this will need to be significantly overhauled, as it would
have to work for any wl_surface, including subsurfaces, so we would need
surface-level discretion.

If the client destroys the pointer resource, we shouldn't unfocus the
surface, and we should regrab it when the client gets the pointer
resource again.
This also fixes a crash at surface destruction because of the unchecked
wl_link_remove that will happen on both pointer and surface destroy.
This reverts commit 283a81eac0.
This can't be done yet, as it will crash when we try to do a destroy
effect from a plugin. The surface actor needs to outlive the surface
in this case.
Though, the unparenting happening is wrong anyway for a destroy effect.
We need to figure out a sane way of doing this unparenting only after
all effects have finished.
As resource destruction can happen in any order at shutdown, we
need to be flexible here. A client disconnecting without cleaning
up all its resources should not assert fail.
The input region was set on the shaped texture, but the shaped texture
was never picked properly, as it was never set to be reactive. Move the
pick implementation and reactivity to the MetaSurfaceActor, and update
the code everywhere else to expect a MetaSurfaceActor.
I tested this with meta_window_get_input_rect and decided to change
it at the last minute. Turns out meta_window_get_rect is unlike all
the others. Just access window->rect directly instead.
Now that we call set_custom_frame_extents, the frame rect corresponds
to the "visible window geometry" used for constrainment, while the
x/y fields in get_xdg_popup instead are relative to the surface.
Something noticed on code inspection. If we have a popup grab,
it will always return FALSE. The code here clearly meant to continue
if we had an existing popup grab from an existing client.
Both the pointer/keyboard resource and surface resource can be destroyed
at any point in the destruction process, so we need to have destroy
listeners on both. To make the code easier to follow, rename ->focus
to ->focus_surface at the same time, and rearrange the code so that
the two of them are always grouped together.
To prevent the MetaSurfaceActor from being destroyed, we normally
unparent it before we unmanage the window. However, this doesn't
work for XWayland windows, which we unmanage when we get UnmapNotify
or DestroyNotify, not when we get the wl_surface_destroy.
To solve this, add an early hook in meta_window_unmanage that
unparents the surface actor if we have one. At the same time, clean
up the destruction code to remove old comments and assumptions about
how wl_shell behaves.
This was a bad idea, as ping/pong has moved to a client-specific
request/event pair, rather than a surface-specific one. Revert
the changes we made here and correct the code to make up for it.
This reverts commit aa3643cdde.
We want to remove a bunch of auxilliary duties from the MetaWindowActor
and MetaSurfaceActor, including some details of how culling is done.
Move the unobscured region culling code to the MetaShapedTexture, which
helps the actor become "more independent".

This is considered "undefined" by upstream. Right now GTK+ does this
a lot, so we shouldn't crash. Let's make them crash instead and send
them an error instead.
Use our new "surface_mapped" field to delay the showing of XWayland clients
until we have associated together the window's XID and the Wayland surface ID.
This ensures that when we show this window to the compositor, it will properly
use the Wayland surface for rendering, rather than trying to use COMPOSITE and
crash.

Moving the mouse over weston-terminal, we can see several issues:
* it often updates late, or not at all
* the attachment of the pointer sprite is wrong
These are because we willy-nilly call seat_update_sprite all over the
place, and often in wrong areas. Set up a set_pointer_surface helper
method that will do the right thing for us in all cases, and call it
on transitions.
Currently, set_cursor isn't properly working. Often, the requests look
like this:
cursor_surface = wl_compositor.create_surface()
cursor_buffer = create_cursor_buffer()
cursor_surface.attach(cursor_buffer, 0, 0)
cursor_surface.commit()
wl_pointer.set_cursor(cursor_surface, 7, 14)
But since the surface doesn't "have a role" when the commit comes in,
we ignore it, and don't do anything with the pending buffer. When
set_cursor is called, however, we don't immediately update anything
since it doesn't have a buffer.
This effectively means that set_cursor has unpredictable side effects.
Weston's toy toolkit reuses the same surface for every buffer, so it
only fails the first time. In clients that use a new surface for every
cursor sprite, the cursor is effectively invisible.
To solve this, change the code to always set the buffer for a surface,
even if it doesn't have any real role.
Refactor our commit() implementation out of wl_surface_commit(),
and pass the double-buffered state around to all our implementation
methods. This allows us to drop a few lines destroying and
reinitializing list of frame callbacks. This is a big cleanup for
the next commit, though.
To prevent corruption, our focus listener needs to be removed even when
the surface is destroyed. So, bailing out when pointer->focus->resource
is NULL just isn't good enough.
Implement support for synchronous subsurfaces commits. This means that
the client can, by calling wl_subsurface.set_sync, cause its surface
state to be commited not until its parent commits.
This will mean there will be will potentially be one more surface state
(regions, buffer) at the same time: the active surface state, the mutable
pending surface state, and the immutable surface state that was pending
on last surface commit.

This reverts commit ebe6e3180e.
This is wrong, as mutter's controlling TTY may not be the same
as the active VT, and in fact won't be in the case of systemd
spawning us.
The "correct" API for this is to use David Herrmann's
"Session Positions" system to switch to another VT:

As logind can give us a new FD at any time when it resumes. Theoretically,
this is still technically wrong, as the MetaCursorTracker holds onto it.
We'll fix this after we port to logind.
When we have a new client, we potentially set the focus on one of its
surfaces when we map it but the client might not have called
wl_seat.get_keyboard/pointer yet. When it finally calls
get_keyboard/pointer we must then register its resource as the
focus_resource which means that we can only return early if
focus_resource is already set.

Otherwise clutter events don't have their source actor properly set
and we aren't able to determine the MetaWindow to which a given
keybinding applies.
https://bugzilla.gnome.org/show_bug.cgi?id=719724
Since subsurfaces won't have toplevel MetaWindowActors, we need to
use MetaSurfaceActor instead. These are embedded in the MetaWindowActor,
just like MetaShapedTexture was (in fact, MetaSurfaceActor now contains
a MetaShapedTexture)
Somebody could do:
$ mv my-evil-program mutter-wayland
$ PATH=.:$PATH mutter-launch mutter-wayland
It's not secure, and it's hard to test with, so just drop it for now
We'll be relying on logind to hand us permissions in the future.
