ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

When a fullscreen application is focused,
toggling the overview via hot-corner is disabled,
even when the overview is currently visible.
This only makes sense, when the overview is
hidden to not to disturb the behaviour of the
fullscreen application, but leaves an
inconsistency when the overview is visible since
it should work there like when a non-fullscreen-
application is focused.
So, always allow hiding the overview using the
hot corner when the overview is visible.

LayoutManager is currently a pure JavaScript class that
relies on the rudimentary Signals.addSignalMethods() to
handle signals. This is an inefficient implementation of
one of the most central classes in GNOME Shell.
In addition to removing Shell.GenericContainer, then,
turn LayoutManager into a proper GObject.Object subclass.

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

We were handling being initially headless by only setting the primary
and bottom monitor if there was any primary monitor, then checking the
primary monitor reference before making calls assuming there was any
monitors.
What we didn't do was unset the primary and bottom monitor when going
headless, meaning that temporarly disconnecting a monitor while having
windows open caused an assert to be triggered due to various code paths
taking the path assuming there are valid monitors.
Unsetting both the primary and bottom monitor when going headless avoids
the code paths in the same way as they were avoided when starting
headless.
https://bugzilla.gnome.org/show_bug.cgi?id=788607
Don't assume there will always be a primary (logical) monitor, or any
(logical) monitor at all. This includes not allocating / layouting /
styling correctly when being headless.
The initial background loading will also be delayed until there are any
(logical) monitors connected.
https://bugzilla.gnome.org/show_bug.cgi?id=730551
Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.
https://bugzilla.gnome.org/show_bug.cgi?id=785084
let trackChrome accept actors that are not children of chrome actors.
this will be useful for the MetaCloseDialog in gnome-shell, which
is already included in the MetaWindowGroup, but needs to be tracked
as chrome for the dialog to receive pointer events on X11.
https://bugzilla.gnome.org/show_bug.cgi?id=762083
It's possible for updateRegions() to be called before monitors have
been properly initialized. Instead of throwing an error in that case,
just skip the strut computation (that doesn't make sense anyway without
a monitor).
https://bugzilla.gnome.org/show_bug.cgi?id=781471
findMonitorForActor() may be called before the layoutManager gets
to initialize monitors, so make sure the monitor index is in range
to avoid a warning.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
Commit c39ffa111 moved the signal handling from the controls- to the
background-group to enable scrolling on non-primary monitors.
However this broke scrolling on reactive overview elements as the
workspace switcher, as they're not descendants of the background.
To fix, move scroll-event handling to the overview group itself,
which is the common ancestor of all overview elements.

When we restart, we need to update the struts for the screen before
we enter the main loop, or maximized windows will get resized to the
size of the screen without struts, then resized back.
A workaround is needed for a Clutter bug that occurs when we get
the size of an actor before the first paint of the stage.
https://bugzilla.gnome.org/show_bug.cgi?id=761566
When chrome is added with the trackFullscreen parameter, the actor's
visibility will be updated automatically whenever its monitor's
fullscreen state changes. However as we currently ignore the fullscreen
state at the time the chrome is added, the initial visibility may well
be incorrect - fix this by updating the initial visibility as necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=749383
For barriers like the hot corner which are made up of multiple axis
barriers, make sure that all the barriers have been left before
resetting the barrier.
NVIDIA drivers don't preserve FBO contents across suspend / resume
cycles which results in broken backgrounds. We can work around that by
forcing a refresh when coming out of suspend.
https://bugzilla.gnome.org/show_bug.cgi?id=739178
Since commit e189a34, the trayBox uses a Contraint to cover the primary
monitor's work area. This allows banners to be clipped so they don't
leak into monitors above the primary one during animations. However even
without being reactive, the trayBox now interferes with operations like
Looking Glass' object picker and overview DND.
With the trayBox no longer being positioned manually, there's no strong
reason to keep it in LayoutManager, and handling it in MessageTray allows
to hide the actor while no banner is showing, which helps with the issue
outlined above.
https://bugzilla.gnome.org/show_bug.cgi?id=744912
The panel is not visible when in fullscreen, but critical notifications
may still be shown - having them pop out from where the panel would be
looks unpolished, so adjust the trayBox accordingly.

It was removed as actors that should not affect the input
region can simply be added to the uiGroup instead. However
the property is useful to add non-reactive chrome, but then
use trackChrome() to add a child to the input region.
This reverts commit e62d22a50e.
https://bugzilla.gnome.org/show_bug.cgi?id=744850
Occasionally it makes sense to constrain to a monitor's work-area
rather than the entire monitor, so implement that behavior and add
a property to turn it on.
https://bugzilla.gnome.org/show_bug.cgi?id=744850
Don't assume struts are on the primary monitor while computing
the strut side. Instead, find the first monitor that overlaps the
strut and compute the strut side using it.

Since the background rework, SystemBackground is no longer a transparent
actor that you have to stack on top of a solid background, it is an
opaque actor. Fix the color of the background actor, and remove places
where we were setting the background color underneath the system background
and expecting blending - in particular, we can always set no_clear_hint
on the stage.
https://bugzilla.gnome.org/show_bug.cgi?id=738652
When monitors change, the previous index might not mean the same
physical monitor anymore, in fact, it might become invalid. In the
latter case, we'll actually get a JS error when accessing
this.keyboardMonitor in _updateKeyboardBox() . To avoid this, let's
just always reset the OSK to the primary monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=738536
If we have a modal, the stage's input region doesn't really matter --
all events go to us anyway. To avoid doing extra work doing animations
when we have a modal, like menus, the overview, and the message tray,
just fizzle out all updates.
To make sure we catch updates, update the input region whenever we end a
modal.
https://bugzilla.gnome.org/show_bug.cgi?id=737001
The rewrite of Mutter's background code (see bug 735637) requires
corresponding changes here - we no longer need to layer multiple
MetaBackgroundActors together.
The general strategy is that a BackgroundSource object is created
per GSettings schema, and keeps either one Background/MetaBackground pair,
or, for animation, a Background/Metabackground pair for each monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=735638
Support was added to Mutter to allow it to trigger a restart
to allow for restarts when switching in or out of stereo mode.
Hook up to the new signals on MetaDisplay to show the restart
message and reexec. Meta.is_restart() is used to suppress
the startup animation.
This also allows us to do 'Alt-F2 r' restarts more cleanly
without a visual flash and animation.
https://bugzilla.gnome.org/show_bug.cgi?id=733026
NetWM struts are defined in terms of screen edges (rather than monitor
edges), which works poorly with vertical monitor layouts (as it renders
entire monitors unusable). Don't extend struts in those cases.
https://bugzilla.gnome.org/show_bug.cgi?id=663690
This code may have worked when written in 2009, but later gjs commit
b5e467d89aea43a8e32a1138d232c8a32e6b0785 removed the priority
parameter from idle_add.
Now, when running a constantly-updating client (es2gears) on an
embedded platform, _updateRegions() does not get called and I see
unresponsive window decorations.
Update the code to use meta_later_add() like other parts of the
shell, which is actually slightly better in this case anyway.
Solves the unresponsiveness problem.
https://bugzilla.gnome.org/show_bug.cgi?id=585500
If an actor is destroyed, calling get_transformed_size()/position()
can return bogus values and trigger JS exceptions.
This can happen if a tracked actor comes from an extension
(such as classic mode's window-list) and that extension is
deactivated.
https://bugzilla.gnome.org/show_bug.cgi?id=723661
Right now we have three "dummy cursor" widgets between the background
menu, the message tray menu, and the IBus candidate popup. Consolidate
these into one "dummy cursor" widget which is tracked in the layout
manager.
If monitor-changed fires at startup, it will destroy all of the
backgrounds, but since this._isStartup is true, won't recreate any
of them. Additionally, since _bgManagers is indexed by monitor index,
if the primary index is not 0, it could become a sparse array (e.g.
[undefined, undefined, primaryBackground]), and our for loop will
crash trying to access properties of undefined.
Fix both of these issues by always creating background managers for
every monitor, hiding them on startup but only showing them after
the startup animation is complete.
One thing we need to watch out for is that while LayoutManager is
constructing, Main.uiGroup / Main.layoutManager will be undefined,
so addBackgroundMenu will fail. Fix this by passing down the uiGroup
to the background menu code.
https://bugzilla.gnome.org/show_bug.cgi?id=709313
We cannot wait for the queued update region to fire when
xdnd is being used because a wrong input shape can result
into a xdnd leave event when the user moves the pointer fast.
https://bugzilla.gnome.org/show_bug.cgi?id=708887
Don't assume that this._bgManagers.push() (i.e adding to the end) is always
correct.
On startup we call _createPrimaryBackground which passes in the primary index
which may not be 0.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
The top_window_group was introduced for popup windows that should
appear above system chrome, but as the group itself is just a child
of Main.uiGroup, chrome that is added after top_window_group will
still be stacked on top.
At least correct the stacking for actors added via addChrome().
https://bugzilla.gnome.org/show_bug.cgi?id=702338
In order to make sure that the struts and regions are initialized,
we need to make sure that we do with the conditions that nothing
is transformed, like the uiGroup, and that everything is visible.
These invariants broke during a fix to hide the UI until the
system background texture could be loaded. Now, reorder things so
that the system background is loaded, and then the UI is properly
loaded, and so on.
https://bugzilla.gnome.org/show_bug.cgi?id=696159
Instead of using the input mode, when the overview is not modal
it should use a Chrome-tracked actor, that is added to the input
region. Because the overview always takes pointer input when
visible, the actor is added at startup, and it is shown and hidden
as needed.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
Since we now have global.screen::in-fullscreen-changed, remove the
duplicate signal. To prevent ordering problems in connecting to
this signal, make inFullscreen a property-function of a new Monitor
object rather than a data property we tack on to a Rectangle object.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
This ensures that when we have windows that are already visible,
like desktop icons, they don't fly across the screen from what
seems to be hyperspace to get into view.
https://bugzilla.gnome.org/show_bug.cgi?id=696323
In the (no barriers) fallback case handleDragOver has somehow
ended up being turned into a nop and thus breaking xdnd
overview opening.
Fix that by calling _toggleOverview() when a xdnd source triggers
it.
https://bugzilla.gnome.org/show_bug.cgi?id=696447
Getting fullscreen window tracking right in GNOME Shell turned out to
be very hard, because it depended on details both how Mutter handled
fullscreen windows and the exact timing of that. Fullscreen tracking
and auto-minimization of fullscreen windows that lose their fullscreen
status has thus been implemented in Mutter: use that.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
It's possible in some corner cases for the status of the topwindow
to change and make it not fullscreen without ::restacked being
changed. One way that it could happen with the old code was if the
layer of the top window changed from NORMAL to FULLSCREEN.
Change the logic not to look at the layer, which is a function of
Mutter's *intended* stacking, rather than the *actual* stacking,
which is what ::restacked gives you. Instead, look at the top
portion of the stack, down to the first non-override-redirect
window, and see if their are any monitor-sized windows there.
Connect to changes on the top portion of the stack, so we know
if conditions change.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
It makes more sense to use the monitor the tray is on, rather than the
primary monitor. This also matches us with whether we can open the tray
from a barrier/dwell or not.
https://bugzilla.gnome.org/show_bug.cgi?id=695659
For the same reasons that we disable the tray barrier, we should
disable hot corners as well -- when users have a full-screen game
open, we shouldn't allow overview activation by the hotcorner.
https://bugzilla.gnome.org/show_bug.cgi?id=694997
Rather than expose a dizzying array of methods related to managing
state that require infecting every user of the overview methods, try
to do the sensible and smart thing internally. Now, the overview
itself tracks when XDND drags start, and simply calling show, hide or
toggle while an XDnD drag is in effect will show the overview, and
will only take the grab until after the XDND drag ends.
https://bugzilla.gnome.org/show_bug.cgi?id=663661
This cleans up the code considerably, and makes it so that
one path creates all hot corners for all monitors. Why this
wasn't done originally, I have no clue...
The one complication is debouncing if the button and hot corner
are triggered in rapid succession, so we just move this tracking
to the overview.
