We destroy the widget that is wrapped around the drag window
when the object data on the drag context gets cleared. Destroying
the window before that happens leads to unpleasantries. E.g. we may
try to access the frame clock, which doesn't exist anymore, and
things go downhill from there. So, keep the window alive for
a little longer.
X11 has the notions of "transient for group", and while it's an ICCCM
violation, it's commonly used and documented that a window manager
would treat a window with transient_for set to None to transient for all
windows of its group.
gtk uses this when an application sets a dialog type window but does not
specify an explicit transient.
While this works on X11, there is no such thing as groups in Wayland and
the closest equivalent which is set_parent() in xdg-shell takes only one
parent. This is what is used for modal dialogs.
To get something similar in behavior to what is available on X11, a
solution is to update the parent() of the dialogs without transient when
the active surface changes.

Quite a few applications use GTK_WINDOW_POPUP to create various
temporary windows and place then on screen. That works fine on X11 but
on Wayland there is no global coordinate system for regular surfaces.
If the application is using a gdk temp window and set a parent with
gtk_window_transient_for(), the gdk wayland backend has all it needs to
create a subsurface that can be placed at will by the application.

In most places, we can do with the pointer/keyboard of the default seat
instead of the client pointer. We can also remove some code from
gdk_input_init() because we know for sure there's no floating devices to
care about here.
Gdk Wayland backend walks up the transient windows tree, but does not
check for cycles when doing so.
As a result, if two or more windows are transient to each other, the
Wayland gdk backend will enter an infinite loop.
While this is clearly a bug in the application, gtk+/gdk should be more
robust and handle such errors more gracefully.
To avoid looping infinitely at various point in the code, check for a
possible loop when setting the transient relationship and deny the
request to set a window transient for another if that would create a
loop.

We no longer need a grabbed seat, instead we'll just use the default
seat if this happens, not without first warning and recommending
gdk_seat_grab() for the operation.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
This allows GDK to unset the grab itself. Also, make sure we unset
the "pointer emulating" touch on the device if this is the
pointer emulating sequence.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
GdkWaylandDeviceData conceptually gathers the data that belongs to
a seat, so it's been renamed (although the old typedef stays, plenty
of refactoring is due here...).
The methods in GdkSeatClass have also been implemented, the most
remarkable is ::grab, which ensures the grab is performed on all
the relevant "master" devices.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
On some systems, the gtk settings are not used properly for wayland.
Indeed, g_settings_schema_source_get_default is used, and as the docs says it,
"all lookups performed against the default source should probably be done
recursively.".

Add a variant of gdk_drag_begin that takes the start position
in addition to the device. All backend implementation have been
updated to accept (and ignore) the new arguments.
Subsequent commits will make use of the data in some backends.
In Wayland, the hotspot of a DND icon is set using the buffer offset in
wl_buffer.attach. To implement this, add a private API to cause the
next wl_surface.attach to offset the new buffer with a given offset.
Setting a DND icon hotspot sets this offset while also queuing a redraw
of the window to trigger the wl_surface.attach.

gdk-wayland backend would not re-configure a surface when its size and
scale match the known size and scale.
But there might be a pending xdg_surface_configure() that would revert
this change so we should re-configure even if the currently known
size/scale match, otherwise we may end up with a wrong size after the
xdg_surface_configure() is received.

If we "release" the button first, the drag will be eventually cancelled,
we must first signal GDK_DROP_FINISHED, and then release the button so
the success status prevails.
It doesn't make a lot of sense to have this stored as data offer data,
rather together with the source_targets array, which is what we're
poking here in the end.
https://bugzilla.gnome.org/show_bug.cgi?id=758713
Dissociate ownership from our maintenance of wl_data_source objects.
The only place where ownership must be updated together is
data_source.cancelled, for the other places GDK should take care of
setting up the right ownership, even if at a different order than
we'd expect here.
This fixes GTK+ apps on wayland being locally confused about the
current selection ownership. Because gtk_selection_add_targets()
results in a wl_data_source being created, and ownership being
updated right away, early callers of this will change the ownership
even if the widget it's being called on didn't explicitly request
the selection ownership yet.

Instead of having our own copy of the pointer gestures XML file, use
the one installed by wayland-protocols.
Since pointer gestures is an unstable protocol, it went through the
unstable protocol naming convention changes, which is reflected in this
commit.

After the grab is finished, we would expect an enter event, and
GDK updating internally the cursor for that window and device.
This means there is no need at all to store it separately in the
backend.
As a side effect, animated cursors are now also possible on grab
icons.
https://bugzilla.gnome.org/show_bug.cgi?id=735847
Other backends take care of the cairo surface destruction in
GdkWindow::destroy. We must do the same here, or the cairo_surface
and its corresponding wl_buffer are left dangling.
https://bugzilla.gnome.org/show_bug.cgi?id=747295
If the buffer of a cursor is NULL, for example if its an empty cursor,
just set the cursor surface to NULL as well. Not doing this we'll use
uninitialized hotspot coordinates, dimensions and scales.

This GdkDragContext should be created even if we don't have pointer
capabilities. Make it created on add_seat(), and only set the device
on wl_seat.capabilities, so it can be set to either master pointer.
https://bugzilla.gnome.org/show_bug.cgi?id=741066
We use the high-level gdk_device_get_window_at_position() to figure
out the window, although this one actually tries to find out the
current window under the device coordinates, which might well fall
outside the window, so NULL is returned in those cases.
Fix this by using the lower level _gdk_device_window_at_position()
that will return the toplevel without further lookups, so is more
desirable here.
https://bugzilla.gnome.org/show_bug.cgi?id=758250
Now that we have multiple master pointers, this call may pick the wrong one.
Instead, pick the GdkWaylandDeviceData from the first device, and pick the
master pointer from there.
The common GDK code accounts for "pointer emulating" touch sequences to be
synchronized with the pointer position by the windowing system.
However on Wayland pointer and touch are completely independent, the backend
attempts to implement pointer emulation, but doesn't account for the
possible crossing events happening when the user switches from pointer to
touch or the opposite.
In order to fix this, and to ensure we don't have to interact with the
master pointer (which backs the wl_pointer), separate the touch interface
to have its own master pointer, and ensure crossing events are emitted on
it, so the picture of an "emulated pointer" is complete above the backend.
Inspired in a former patch by Jonny Lamb <jonnylamb@gnome.org>
https://bugzilla.gnome.org/show_bug.cgi?id=750845
We were using that range for the extra buttons after left/right/middle,
while this is harmless for clients not handling extra buttons (we
used to translate those button events into scroll events in x11 anyway)
this will be unexpected for clients that do handle additional mouse
buttons themselves (eg. back/forward buttons present in some mice).
In order to remain compatible with X11, those need to be assigned from
button 8 onwards.
Also, include input.h, and stop using magic numbers here.
https://bugzilla.gnome.org/show_bug.cgi?id=758072
Make sure the wayland backend sets a new geometry when the client
resizes itself, otherwise the compositor won't be notified and may
revert to the old size on state changes.

problem in gtk+.

If a GtkMenu (or something else that is mapped as a xdg_popup) tries to
use a subsurface window as a parent, it will be terminated by the
compositor due to protocol violation. So to avoid this, if a parent
window is not a xdg_popup or xdg_surface, i.e. a wl_subsurface, then
traverse up the transient parents until we find the right popup parent.
https://bugzilla.gnome.org/show_bug.cgi?id=756780
Tooltips tend to be placed on top of a parent surface with a given
relative coordinate, and without any input focus. So lets map them as
subsurfaces.
https://bugzilla.gnome.org/show_bug.cgi?id=756496
Restructure the mapping procedure so that its known up front what the
expected way mapping is to be done (subsurface, popup or stand alone),
and warn if it fails to actually map in such a way (for example a popup
without a parent or device grab, a tooltip without a parent).
https://bugzilla.gnome.org/show_bug.cgi?id=756496
GDK_NOTIFY_ANCESTOR would happen when the pointer crosses across a direct
parent/child. However nonlinear events are more likely, specially when
the pointer moves across toplevels (either different apps, or menus being
popped up over the pointer position).
This makes popping up comboboxes and other menus that fall over the pointer
position possible. With the previous detail the GtkMenu code misinterpreted
the crossing event, making it think the button release coming right after
should dismiss the popup, which made menus just flash on the screen unless
you kept the button pressed.
If the shared context is in legacy mode, or if the creation of a core
profile context failed, we fall back to an EGL context in compatibility
mode.
Since we're relying on a fairly new EGL implementation for Wayland, we
don't fall back to the older EGL API, and instead we always require the
EGL_KHR_create_context extension.
https://bugzilla.gnome.org/show_bug.cgi?id=756142
keyboard_handle_leave() might be called with a NULL surface resource
(for example if the surface was destroyed after the event was sent). If
so, we should still deal with the keyboard focus lost event, otherwise
we will both leak (the keyboard_focus GdkWindow reference) and miss
stopping the key repeat timer.
https://bugzilla.gnome.org/show_bug.cgi?id=755927
gdk_wayland_device_update_window_cursor() is inconsistently returning
TRUE/FALSE, despite the timeout being always replaced for new cursor
frames. This could end up in these timeouts being "leaked" and running
as long as the window has an animated cursor.
Fix this by making it really sure we return G_SOURCE_REMOVE, although
now we keep track of animation delays, so the timeout will be reused
for constant time animations.
Initially the subsurface will be in synchronized mode and we will leave
it like this until the first time the parent surface has been committed.
The reason for this is because the subsurface position will be applied
as part of the parent surface state, and we need to synchronize the
initial position with the initial frame, so that we don't accidentally
draw the subsurface at the default position (0, 0) which would happen in
desynchronized mode if the subsurface content is committed before the
next parent surface commit.
https://bugzilla.gnome.org/show_bug.cgi?id=754839
If we are using gl for drawing, we don't have a shm surface,
so don't assert that we do. Instead, only call shm-specific
apis when they make sense.
This fixes a crash when showing popovers over a GtkGLArea,
as seen in gdkgears.

When receiving a selection or when a drag icon enter a window, it was
targeted at a specific window. Lets emit the GDK_OWNER_CHANGE event
only for this window, instead of broadcasting.
Broadcasting has some nasty side effects. For example, if there was n
GdkWindows, and one would for every "owner-change" signal handler
receive n signals about the owner being changed.
An example of where this went a bit out of hand was gnome-terminal,
which added one listener per terminal window. This meant that if
one had m number of terminal windows, each time any one would loose or
gain keyboard focus, O(m^2) owner-change events would be emitted.
https://bugzilla.gnome.org/show_bug.cgi?id=754158
The code in _gdk_wayland_window_dispose was not safe against
being called twice - it would call g_hash_table_destroy twice
on the known_globals hash table, the second time operating on
freed memory. It was also leaking the list of async_roundtrips.
After fixing both of these issues, the displayclose testcase
now works on Wayland.
We call gdk_wayland_window_hide_surface when the window gets
destroyed, and in this case, the frame clock might not exist
anymore.
This was showing up in the displayclose testcase.
While we do not have subwindows in Wayland, we do create an
artificial root window. When the display is closed, the root
window gets destroyed, causing recursing to be true for the
toplevel windows.
As the protocol is still considered unstable (meaning not backward
compatible), we should, as stated in the protocol, only bind the version
advertised is the version we implement.
https://bugzilla.gnome.org/show_bug.cgi?id=753856
Prior to this patch, the ID of the GtkApplication was always used for
clients which were GtkApplications. This would only be guaranteed to be
correct for D-Bus activatable programs. As a result, all
non-D-Bus-activatable applications would set the wrong ID making the
shell unable to find the corresponding .desktop file.
This change makes it so that the GDK backend always uses the name
passed to g_set_prgname, or the default value if not explicitly set, as
this more often corresponds to the .desktop file.
This means that in order to make D-Bus activatable applications set the
correct application ID, they must, for now, manually call
g_set_prgname() with their application ID (basename of the .desktop
file).
If g_get_prgname() returns NULL, fallback to gdk_get_program_class()
even though it will most likely never be correct according to the
xdg_surface.set_app_id specification.

wl_log() currently logs using G_LOG_LEVEL_ERROR
(which is fatal). The wayland client library doesn't
expect this behavior. It uses wl_log to log recoverable
errors.
This commit changes the log level to G_LOG_LEVEL_DEBUG
instead.
https://bugzilla.gnome.org/show_bug.cgi?id=753635
On wayland, the gestures protocol defines a wl_pointer_gestures global
object, that will match in number with wl_seats, swipe and pinch
interfaces can be obtained from it, which events are translated into
GdkEventTouchpadSwipe/Pinch events.
Only a drag context which was created with 'drag_begin' will be
guaranteed to have a source window at all times. Thus, in finalize we
cannot assume we can retrieve a GdkDisplay from the source_window
pointer since it may be NULL. Though, the display is only needed for
contexts created via 'drag_begin' thus we can retrieve it after
checking that is the case.

We need to be mapped to have a gtk_surface and thus be able to do
requests on it so we need to save the modal hint and apply it when we
get mapped so that code that sets the hint before showing a window

-1 means that we have no specific preference for an initial
fullscreen monitor, and -1 is less than the number of monitors,
so we would end up accessing invalid memory. Prevent that.

Prior to this patch, the hotspot would be passed in buffer coordinate
space. Where this were ever tested, i.e. in a patched mutter, the
server interpreted them incorrectly, which meant it went undiscovered.
In the updated mutter patches the incorrect behavior in GTK+ was
discovered due to the behavior in mutter was corrected.
In the themed cursor case, the dimensions were not correctly scaled
either, but this had no negative visible effect because the dimension is
only used for reporting damage tracking, and passing a bigger damage
region than surface has no negative visible effects.

Under Wayland, fullscreen/maximized windows may not cover the entire
area when a size increment is specified.
Ignore size increments for fullscreen/maximized windows just like most
window managers do under X11 so that windows with size increments can
still be fullscreen or fully maximized under Wayland as well.
https://bugzilla.gnome.org/show_bug.cgi?id=751368
We mistakenly forced the "STRING" type, which was able to confuse higher
layer helpers like gtk_selection_data_get_uris(). This fixes a crash
happening anytime a drop is attempted on a GtkPlacesSidebar.
Currently, due to the lack of progress information in the Wayland DnD
protocol, we assume a DnD operation is finished after the first
data_source.send is finished (It's either that or leaving stuck grabs).
This however breaks previous assumptions that dest widgets can request
the data multiple times, even in response to GtkWidget::drag-motion.
This leaves us with a NULL owner for the DnD atom when we aren't
finished receiving wl_data_source events yet, causing a crash.
This commit fixes the crash, the behavior left is still far from
desirable though...
And force the ungrab on it, instead of the slave, in the case of
local DnD drop. This avoids confusions on the pointer events spawn
from DnD, as GDK doesn't think anymore those are from a slave device.
Most namely, it fixes the stuck grab when finishing DnD on the
same app it was started from.
We currently only hold the last offer received, which is wrong, as both
are independent and have different life cycles.
This means we have to store per-selection wl_data_offer and targets, and
maintain these as appropriate from the clipboard/DnD specific entry points.
This oddly can be reproduced with weston+weston-dnd, when dragging
anything from GTK+ into weston-dnd, it will insist on picking its
custom application/x-wayland-dnd-flower mimetype, and this request
forwarded by the compositor, even if GTK+ didn't announce it on
its wl_data_source mimetype list. (What should probably happen here
is that the request is silenced, and/or weston-dnd picks (null))
This should be harmless, we are leaking though the fd in that case,
because the emission of GdkEventSelection on an unhandled mimetype
results in NOP. In order to avoid this, we should check whether the
mimetype is supported at all on the backend code and possibly close
the fd, this involves storing these in the first place.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
If the other peer requests data too fast (too rare/unlikely though),
we might receive multiple gdk_wayland_selection_request_target() calls
with no ending gdk_wayland_selection_check_write(), in which case the
fd is leaked as no GOutputStream was created to take over it.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
We weren't catching all the places where the AsyncWriteData operation
should be cancelled, which could happen if we repeatedly request the
same target on different fds.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
At the moment we create the AsyncWriteData, the ownership of the
fd is granted to the GOutputStream, and the fd set to -1, so at
this moment we're just silently getting EBADFD.
This partially reverts 25885ca600, the initialization of .fd
to -1 is valid and stays though.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
On X11 this is something the windowing system does for us, which the
wayland backend should emulate, being grabs completely client-side.
So, if the grab and current focus windows differ, make sure we emit
focus/crossing events as it corresponds to the grab device.
This was being done so only on pointers. Internally, a GdkDeviceGrabInfo
is kept for each of the master pointer/keyboard, failing to do this for
keyboards results in a stuck keyboard grab.
https://bugzilla.gnome.org/show_bug.cgi?id=748892
The fd must be closed on async_write_data_free(), but we should also
initialize it to -1 so gdk_wayland_selection_check_write() doesn't wrongly
pick the stdin fd.
https://bugzilla.gnome.org/show_bug.cgi?id=751414
A subsurface positioning operation only takes effect when the parent
surfaces state is applied. If a subsurface is mapped and positioned, but
the parent surface state is not immediately committed, the relative
position of the subsurface is undefined and may be placed incorrectly.
To avoid this undefined state, always request that the parent surface
should be committed after mapping a subsurface so that the position
operation will take effect.

If a menu was not attached to any widget, we try to calculate its
position given where the grabbed pointer is and what window has its
focus. Previously we failed to do so if a "transfer window" was used
for the grab, and this patch adds a code path that, if the menu window
itself didn't have the grab, look for the transfer window and get the
grab device from there.

According to the xdg-shell protocol specification the (x, y) coordinates
