Instead of having everything clumped at MetaWaylandDataManager,
split the primary selection to its own struct. This manager is
handled separately from wl_data_device_manager and other selection
managers, so they would be able to interoperate between them, even.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
This is still an openly defined struct, as we will need accessed
by "subclasses". Same principle applies than with the
MetaWaylandDataSource refactor, this is not meant to introduce
functional changes, so just go with it.
On the bright side, the interactions are now clearer, so it could
be made saner in the future.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1193
The split wasn't 100% clean, and some extra private API had to be
added for it (but well, looking at the API, it's already evident
there's a cleanup/streamlining task due). This is meant to be a
refactor with no functional changes, so just go with it.

We already have a signal callback that translates selection ownership changes to
data_device/primary .selection events. Given both will be run when a data source
is being replaced, and this event emission being deleted is kinda short sighted
in that in only knows about Wayland, rely entirely on MetaSelection::owner-changed
emission.
Fixes spurious .selection(null) events being sent when a compositor-local source
takes over the selection without the focus changing (eg. screenshot to clipboard).

We are meant to send a .cancelled event after the drop is performed
in certain situations, but only for version>3 clients. Since this is
all version 3 business, only set the drop_performed flag for v3
clients. This drops the need to perform version checks at the time
of cancelling (which is present for other usecases in v1).
Fixes emission of wl_data_source.cancelled for v1 clients.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1177https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1203
Interoperation between wl_data_device_manager v1 and v3 got broken
at some point. Ensure that we resort to the "copy" action if either
the drop site or the drag source are from a client that requested v1.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/965
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
as the user chosen action as it should be.
Makes Wayland drop sites aware of the user action as per XDND with X11
drag sources, and still makes modifiers during DnD work.

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.
https://gitlab.gnome.org/GNOME/mutter/issues/591
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.
https://gitlab.gnome.org/GNOME/mutter/issues/878
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.
https://gitlab.gnome.org/GNOME/mutter/issues/878
We were just looking at DnD actions which might still be unset at that
point. Instead of doing these heuristics, store the selection type on
the data offer.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/845
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.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/793
Instead of taking resource and send/cancel funcs, take a
MetaWaylandDataSource, which exposes all the vfuncs to do the same on the
internal resource.
This has the added side effect that only MetaWaylandDataSource has a
pointer to the wl_resource, which may be unset untimely.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
If a data source is destroyed we first unset the resource, and then try to
unref the related selection source. At this point the only event that might
be emitted by the internal selection machinery is .cancelled, so make sure
we avoid it on destroyed sources.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
We are still poking the mimetypes from the previous selection when creating
the new offer. This may come out wrong between changes of the copied
mimetypes.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/789
When starting a DnD operation, mutter would remove keyboard focus from
the client, only to restore it on the data offer destroy.
However, if the DnD fail, the keyboard focus is not restored, leaving
the user unable to type in the focused window, even after clicking in
the window.
That issue would show only on first attempt, as further DnD attempts
would destroy the previous data offer which would also restore the
keyboard focus.
Make sure we restore the keyboard focus on drag end as well.
https://gitlab.gnome.org/GNOME/mutter/issues/747
On drag start, `data_device_start_drag()` issues a keyboard grab, which
in turn will unset the current input focus.
There is not need to unset the input focus in `data_device_start_drag()`
as this is redone in `meta_wayland_keyboard_start_grab()`
https://gitlab.gnome.org/GNOME/mutter/issues/747
MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore

When primary_offer_receive checks if the requested mime_type is supported,
it should check against the list of mime-types supported by the
primary-selection, instead of the list for the clipboard.
This fixes primary selection copy paste from X11 apps to Wayland apps
not working.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/702
On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/335
Commit 70036429bd mixed drag_origin and drag_surface, leading to warnings
and invisible drag icon. Fix this up so we correctly set up the feedback
actor. This will correctly display the DnD icon alongside the pointer.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
When repicking after a surface was destroyed, if the destroyed surface
was the drag focus, we'd try to focus-out from it after it was
destroyed, causing a NULL pointer dereference.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/336
No XDnD events which notify DnD status change comes in Wayland. To emulate XDnD
behavior, MetaDnd checks whether there is a grab or not when the modal window
starts showing. When there is a grab, it processes the raw events from
compositor, and emits DnD signals for plugin.
