+  <description summary="Primary selection protocol">
+    This protocol provides the ability to have a primary selection device to
+    match that of the X server. This primary selection is a shortcut to the
+    common clipboard selection, where text just needs to be selected in order
+    to allow copying it elsewhere. The de facto way to perform this action
+    is the middle mouse button, although it is not limited to this one.
+
+    Clients wishing to honor primary selection should create a primary
+    selection source and set it as the selection through
+    wp_primary_selection_device.set_selection whenever the text selection
+    changes. In order to minimize calls in pointer-driven text selection,
+    it should happen only once after the operation finished. Similarly,
+    a NULL source should be set when text is unselected.
+
+    wp_primary_selection_offer objects are first announced through the
+    wp_primary_selection_device.data_offer event. Immediately after this event,
+    the primary data offer will emit wp_primary_selection_offer.offer events
+    to let know of the mime types being offered.
+
+    When the primary selection changes, the client with the keyboard focus
+    will receive wp_primary_selection_device.selection events. Only the client
+    with the keyboard focus will receive such events with a non-NULL
+    wp_primary_selection_offer. Across keyboard focus changes, previously
+    focused clients will receive wp_primary_selection_device.events with a
+    NULL wp_primary_selection_offer.
+
+    In order to request the primary selection data, the client must pass
+    a recent serial pertaining to the press event that is triggering the
+    operation, if the compositor deems the serial valid and recent, the
+    wp_primary_selection_source.send event will happen in the other end
+    to let the transfer begin. The client owning the primary selection
+    should write the requested data, and close the file descriptor
+    immediately.
+
+    If the primary selection owner client disappeared during the transfer,
+    the client reading the data will receive a
+    wp_primary_selection_device.selection event with a NULL
+    wp_primary_selection_offer, the client should take this as a hint
+    to finish the reads related to the no longer existing offer.
+
+    The primary selection owner should be checking for errors during
+    writes, merely cancelling the ongoing transfer if any happened.

Jonas Ådahl	d340c3a6dd	wayland: Don't unset surface->buffer when wl_buffer destroyed Don't unset the surface->buffer if the associated wl_buffer object is destroyed. The MetaWaylandBuffer doesn't really only represent a wl_buffer object, but also the data (texture) created from the given wl_buffer. Thus, for example destroying a released SHM wl_buffer should not destroy the MetaWaylandBuffer instance, because the texture may still be used. This commit also fixes a race where calc_showing would hide a window because, at the time of calculation whether it should be showing, the surface's buffer had been destroyed as described above. https://bugzilla.gnome.org/show_bug.cgi?id=762716	2016-03-01 13:33:13 +08:00
Carlos Garnacho	43bd057754	wayland: Ensure harder we're dealing with DnD offers/sources In destroy_data_offer() there is code to ensure compatibility when dragging from a v3 wl_data_device to a v2 one, it's however not checking correctly that this is the DnD drag source. The other path should be used otherwise. https://bugzilla.gnome.org/show_bug.cgi?id=762878	2016-02-29 19:55:55 +01:00
Carlos Garnacho	66be0387ee	wayland: Use separate destructor for the gtk_primary_selection_offer Things don't mix well if we use the same destructor than wl_data_offer, Use a separate destructor with no DnD paths whatsoever. https://bugzilla.gnome.org/show_bug.cgi?id=762878	2016-02-29 19:55:55 +01:00

Carlos Garnacho	7c114360d0	wayland: Implement the (so far internal) primary selection protocol Add an additional MetaWaylandDataSource implementation for primary selection sources, and methods to set primary selection offers. Primary selection sets altogether a different channel than the clipboard selection, those don't cross in any way. Also, the bridge for the X11 PRIMARY selection atom has been added, which adds all the necessary handling to translate primary selection both ways with wayland and X11 applications. https://bugzilla.gnome.org/show_bug.cgi?id=762560	2016-02-26 19:51:32 +01:00
Carlos Garnacho	c6aad6e735	wayland: Add gtk-primary-selection protocol This protocol is an internal mirror of the primary selection drafts being proposed for wayland-protocols. No changes besides prefix/suffix changes. https://bugzilla.gnome.org/show_bug.cgi?id=762560	2016-02-26 19:51:32 +01:00
Carlos Garnacho	741dd674f6	backends: rate-filter the emission of MetaBackend::last-device-changed signal It indirectly triggers expensive operations in gnome-shell (js/ui/keyboard.js), which turns out too expensive if we happen to operate the shell simultaneously with 2 devices that will trigger the operations there. So just rate limit the signal emission, defer to an idle and just emit the last device gotten. Worst that will happen is that we may possibly emit the signal on the same device consecutively. https://bugzilla.gnome.org/show_bug.cgi?id=753527	2016-02-26 16:19:15 +01:00

Jonas Ådahl	c22bee19e1	Add --nested command line argument As of "core: start as wayland display server when XDG_SESSION_TYPE=wayland" it is no longer possible to run a nested mutter Wayland session on top of another Wayland session. This patch adds a command line argument to make it possible to force mutter to start as a nested compositor. https://bugzilla.gnome.org/show_bug.cgi?id=758658	2016-02-22 17:03:07 +08:00
