The duality of the Clutter's key focus and mutter's window focus has long been
a problem for us in lots of case, and caused us to create large and complicated
hacks to get around the issue, including GrabHelper's focus grab model.
Instead of doing this, tie basic focus management into the core of gnome-shell,
instead of requiring complex "application-level" management to get it done
right.
Do this by making sure that only one of an actor or window can be focused at
the same time, and apply the appropriate logic to drop one or the other,
reactively.
Modals are considered a special case, as we grab all keyboard events, but at
the X level, the client window still has focus. Make sure to not do any input
synchronization when we have a modal.
At the same time, remove the FOCUSED input mode, as it's no longer necessary.

This causes a debug SpiderMonkey build to fail when it throws an
exception for the missing symbol, but doesn't properly return FALSE
when executing the script.

While it is obviously still an error to call get_theme_node() on a
widget that hasn't been added to the stage hierarchy yet, asserting
on it hasn't proven too successful in avoiding those errors - it's
likely the most frequent reason for crash reports. Just accept that
there'll always be code paths where we can hit this case and make
it non-fatal.

We will allow to use mode-specific overrides; in preparation for that,
move the code so that we only override preferences after initializing
the session mode.

Otherwise they break the "top level window" detection used by the
unredirect code in mutter, causes game windows not to be unredirected
when tray icons are present.

Currently we simply set the gsettings key when activating an input
source. This obviously introduces a time window, between the event that
activates the switch and when the switch is complete, under which key
events are being delivered to applications and interpreted according
to the previous input source.
The patches in bug 696996 introduce a DBus API in g-s-d that allows us
to know when an input source if effectively active. Using that and
freezing keyboard events in the X server until we hear back from g-s-d
we can ensure that events won't be misinterpreted after an input
source switch.

As with the screen recorder, the magnifier already adds its own
copy of the system cursor, so we should not add it again. Just
as in the screen recorder case, we don't address the case where
the cursor should not be included in the screenshot, but the
magnifier adds it anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=700488
The magnifier adds its own copy of the system cursor to apply the
expected transformations, so we don't need to add it again in the
recorder; this avoids two different cursors showing up in recordings,
but doesn't address the case where the cursor should not be recorded
at all, but the magnifier adds it anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=700488
It looks a bit unpolished to overlap our own chrome with the recording
icon, which may happen when an existing adds UI at the bottom edge.
Fix this by using the primary monitor's workarea for the position rather
than the entire monitor.

Attaching gdb and running with G_DEBUG=fatal-warnings is not a very
fast to debug a specific issue (especially if you have warnings at
startup, since then you need to run the shell from a terminal).
Instead, introduce a new SHELL_DEBUG environment variable that can
be set to backtrace-warning, causing a gjs_dumpstack() after every
warning or critical.

Wrap new GtkMenuTracker API that adds an easy way to bind to
tracker items, and use it to add back support for submenus.
This also adds support for a submenu feature that we didn't
have support for before, action namespaces.
https://bugzilla.gnome.org/show_bug.cgi?id=700257
This pulls in new upstream API that Ryan will maintain, removing
code on our side.
Currently, our implementation of submenus will be gone, but this
will be fixed in a few commits.
https://bugzilla.gnome.org/show_bug.cgi?id=700257
We'll need some of these pieces to be introspectable when we port to
GtkMenuTrackerItem. Due to technical limitations in introspection, we
can't put Gtk-prefixed items in the shell namespace, so add them to
a new introspection library instead.
https://bugzilla.gnome.org/show_bug.cgi?id=700257
This is a hack we have in our local fork as compared to upstream;
work on a generic "hook" system in here is ongoing, but until then,
this is the easiest way to do it.
https://bugzilla.gnome.org/show_bug.cgi?id=700257
This includes a rename from the G* namespace to the Gtk* one, which
will help us with introspecting this code. Note that this removes
some of the custom code we added to GActionMuxer to relay event times
to the remote action group. We'll add this back soon.
https://bugzilla.gnome.org/show_bug.cgi?id=700257
Currently we will always record the entire screen. It has been requested
to support recording a specified area analogous to the screenshot API as
well, so add a set_area() method which allows this.
https://bugzilla.gnome.org/show_bug.cgi?id=696247
It is currently not always possible to predict the actual output filename
of a recording - the file-template does not necessarily use an absolute
path and may contain %d and %t escape sequences.
This is OK for fire-and-forget uses like the existing keyboard shortcut,
but we will soon expose the functionality on DBus and consumers of that
API might very well need to access the file after the recording. So do
the same as our screenshot API and add an optional (out) parameter to
record().

Some callers of the keyring prompt keep the dialog up while
processing the prompt. Allow the user to cancel the prompt
while in this state.
This is propagated to the caller, who can cancel the operation
in question when this occurs.
https://bugzilla.gnome.org/show_bug.cgi?id=682830
The shadows are currently rendered by painting the actor we want to
apply shadow on, in an offscreen buffer. The problem is that when this
actor has an allocation padding (ie allocation that isn't at 0x0
relatively to its parent), this padding is added within the offscreen
buffer and as a result the shadow rendering is truncated because the
offscreen buffer size is the size of the allocation box, not the
allocation box + padding.
This patch reposition the actor at 0x0 with rendering it by changing
the initial transformation matrix when rendering the actor offscreen.
https://bugzilla.gnome.org/show_bug.cgi?id=698301
This makes it much easier to implement correct popup-menu behavior
in the case of nested bins.
This fixes the context menu key in application search results when a
result has focus.
https://bugzilla.gnome.org/show_bug.cgi?id=699800
The comment clearly intended that for this to be the case, but a typo
prevented this from actually being done. This fixes the focused state
of the search field not working more than once.
https://bugzilla.gnome.org/show_bug.cgi?id=699799
In most cases, we'll transition between two states on hover / focus.
Instead of recalculating and repainting our resources on state change,
simply cache the last state when we transition.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
The background image, background image shadow and border image are
allocation-indepedent, so we can keep these in the node. Given that these are
are likely cached in the StTextureCache, the slight increase in code complexity
may not be worth caching these textures and materials -- we might be better off
just computing when we need to paint.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
This ensures that two widgets sharing the same theme node won't trample
on each other's prerendered materials if the actors are of different
sizes. This also tries to be very careful to share as much as possible
during a transition.
This has the side effect that if a widget changes state a bunch of times,
we won't cache every state. Since we expect that state changes are
infrequent and that most cases we'll be able to use the texture cache
to do most of the heavy lifting, this cost is much more insignificant
than rendering a number of different actors with the same theme node
and different sizes.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
Since we now share theme nodes between, we shouldn't cache the paint state
across all nodes. As a first step towards putting this in the actor, split
out the state into another structure. Keep it in the theme node for now
so that we don't make too many changes in one commit.
It's possible that some of these pieces of drawing state could be shared
between theme nodes. For the sake of simplicity, assume that none of them
are shared or should be shared. A future commit could identify those that
could be shared and move them back into the theme node.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
We want to put the paint state in the actor rather than in the theme
node, as having two actors with different sizes but the same theme node
is now much less efficient.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
This simplifies the code required to build remote menus and
put all the items in the right place, and makes us share our
implementation with GTK+.

Similar to the existing generic getter methods, add lookup functions
for URL properties like the standard background-image/border-image

The changes from commit b4f5f1e461 and b394d184cc increased the
instructions required for the fade fragment shader. This is over the limit
for some hardware (like intel gen3), which causes the driver to fallback
to software rendering for the shader. The result is that painting a scrollview
that has a fade effect takes around 30 (!!) seconds.
So lets go back to the old effect for 3.8 until we find a solution.
https://bugzilla.gnome.org/show_bug.cgi?id=696404
Previously when a client requests that a window should be docked the
shell would reparent the socket window onto the stage's window and
then use ClutterX11TexturePixmap to get a texture to represent the
window. This will not work if Clutter is no longer using the X11
winsys for example if it becomes its own display server. Instead this
patch leaves the socket window as a child of the root window and lets
mutter create a MetaWindow out of it. If Mutter is acting as a display
server then this mechanism will still work via the headless x server.
The ShellGtkEmbed instance now registers for notification of the
‘window-created’ signal of the display so that it can find the
MetaWindow that gets created to represent the socket window. When this
window is found it is prevented from being displayed on the screen by
setting the actor's opacity to 0. An input shape is then set on the
window to prevent it receiving any input.
Instead of being a subclass of ClutterX11TexturePixmap, ShellGtkEmbed
is now a subclass of ClutterClone. When the MetaWindow is found for
the socket window the clone's source is set to the invisible actor for
the window so it can be displayed in the panel as before.
The ShellEmbeddedWindow no longer needs to know what the stage is
because it no longer reparents the socket window. Therefore the
ShellTrayManager doesn't need to know the stage either so
shell_tray_manager_manage_stage has been replaced with just
shell_tray_manager_manage_screen.
https://bugzilla.gnome.org/show_bug.cgi?id=693438
Pointer tracking is broken when the pointer is over the stage input
area. This is apparently fallout from mutter going to XInput2.
This commit changes the mouse event handling code to also use XInput2.

Curently it is possible to copy the content of password entries,
and paste it elsewhere in clear text. This is undesirable, so
follow GTK+'s behavior and disable the cut/copy actions for
password entries.
https://bugzilla.gnome.org/show_bug.cgi?id=695104
Doing so causes useless full stage redraws and breaks culling
as clutter cannot know how the signal handler affects painting.
So use clutter_threads_add_repaint_func_full instead.
https://bugzilla.gnome.org/show_bug.cgi?id=694988
Since commit b4f5f1e461, the effect is eased in at the scroll
view's edges so that it does not appear out of nowhere. However,
the linear easing used is not the best option, as now the effect
appears so late that content near the edges ends up just being
cut off rather than faded out.
So adjust the easing function to have the effect appear faster.

g_str_has_prefix() will assert when passed NULL, so we need to make

If enabled, scrollbars take away from the allocation given to the
view's content. This is usually preferrable to painting the bars on
top of the content, but there are exceptions, for instance when the
content needs to be centered with regard to the view as a whole.
Add a :overlay-scrollbars property to account for those cases.

We cannot reset the cursor at the next leave event, as that might
happen on a NULL stage and cause a BadWindow error, so do it on
unmap (which is guaranteed to happen before the stage is cleared).

As we use g_slist_prepend for efficiency when building the list
of results before ordering it, we need to make sure we traverse
the list of previous results backwards so that it's built in
the same order.

GdkPixbuf is stored in memory as individual bytes, in strict red-green-blue-alpha
order, while cairo image surfaces are stored as 32bits units whose
order depends on the endianess.
It is probably possible to do something better, taking advantage
of cogl and the GL using the actual component order, but for now
it is easier to use the GDK utility to convert the cairo surface.
https://bugzilla.gnome.org/show_bug.cgi?id=693931
While we were relying on gtk_icon_info_load_icon and friends being
thread-safe, there was no such guarantee, and recent caching that
was added to GTK+ made it non-threadsafe. To replace it, _async()
variants of the icon loading code were added that are thread-safe.
Use those instead of using our own worker threads.

Use GdkPixbuf rather then cairo_surface_write_to_png_stream when saving
