Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.

Since we always keep the active workspace until the user switches
to a different one, we may end up with two empty workspaces at
the end. It's not obvious to users why this happens, and there's
indeed no good reason for the behavior - just remove the trailing
workspace in that case.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/536
GSettings now recognizes per-desktop overrides that can be used
to change schemas' default values for a particular desktop. This
is not entirely unlike our existing custom override mechanism in
mutter, except that it is not limited to keys in org.gnome.mutter,
and it doesn't require a separate schema - the latter means that
we (and gnome-teak-tool) no longer have to figure out the correct
schema for the current login session and just use the original one.

Commit e5c95b910d refactored the workspace animation to also handle
animations that involve all surrounding workspaces, but due to an
ill-advised review comment (guess whose) it broke the animation
for non-neighboring workspaces.
Update the code to handle correctly whether in a given direction:
- we have the target workspace of a given index
- we have a neighboring workspace
- we don't need to animate anything
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/182
When 4fg swipe motion happens, set up early the workspace switching
animation with all surrounding workspaces. This allows us to move
all content back and forth in any direction. This works on both
touchcreens and touchpads.
When the gesture is activated, the same data is reused to follow
up with the tween animation.
The threshold has been also doubled, it was fairly small to start
with, and feels better now that workspaces stick to fingers.
https://bugzilla.gnome.org/show_bug.cgi?id=788994
Besides the separation into distinct functions, the stored data has
been made able to generically store windows from all surrounding
workspaces. All while keeping a special mode to animate between two
workspaces (The usual till now), this is the only mode exercised so
far.
In order to ease animations, all window groups are now children of
a common container, which is then animated.
Fullscreen windows cannot be restored by touch device users unless the
application adds support for it.
As it is unlikely to change all application lets introduce a top edge
drag gesture which unmakes fullscreen windows.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/123
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.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
On the screen shield, the only possible interaction is lifting the
shield. The on-screen-keyboard is not useful for that, and the drag
gesture from the bottom may in fact conflict with dragging up the
shield, so disable it.
https://bugzilla.gnome.org/show_bug.cgi?id=788339
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
The destroy effect currently relies on a monkey-patched property
added from the map effect. However on X11 it is possible that we
did no map animation for a window that is destroyed when the shell
was restarted or had taken over from another WM. Just use the real
MetaWindow property to avoid a warning in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
The fullscreen animation code is now generic enough to handle any
size change animations, so stop limiting it to (un)fullscreen to
get animations on (un)maximize as well.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
Currently, the translation values are set with the assumption that
one of the actors represents a fullscreen window. In order to
generalize it for any size change transition, we can simply swap
the monitor rect with the source or target rect as appropriate,
and translate the actor from the target to the source position by
subtracting the former and adding the latter.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
Since there is already targetRect that represents where the
window is going to move, rename oldRect to sourceRect to
represent from where the window is moving.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
GJS implements a basic signal system that allows monkey-patching
JS objects with signal methods resembling the GObject ones. However
it's clearly not a good idea to replace the actual GObject methods,
so use the proper GObject facilities when inheriting from GObject.
https://bugzilla.gnome.org/show_bug.cgi?id=778660
We have no guarantees on the number of ::size-changed signals that we may
receive, so the _sizeChangedWindow handler may run multiple times, which
leads to multiple calls to meta_plugin_size_change_completed(). So double
check the actor is not already being animated in the _sizeChangedWindow
handler to avoid reentrancy.
https://bugzilla.gnome.org/show_bug.cgi?id=777784
Wayland clients can request their surfaces to be fullscreened before
commiting a buffer which means that we need to handle fullscreen
requests for which the old size is 0x0, preferably without warnings.
Since the mapping animation also runs for these windows, we can simply
bail out and ignore the fullscreen size change.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
Wayland clients are in control of their window size so the existing
mutter plugin API, which assumes size changes are synchronous, doesn't
work for them since when our size-change handler runs the MetaWindow's
size isn't final yet.
To fix this, the mutter plugin API was extended with a size-changed
vfunc that lets us know when the MetaWindow size has actually
changed. This way we can make the window snapshot and get the old
window size on the existing size-change handler and later, on the new
size-changed handler, get the new size and start the animation.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
This is an implementation of the pad OSD that's been previously
present in gnome-settings-daemon. Since things are moving closer
to the compositor, it makes sense to have this implemented as shell
UI.
https://bugzilla.gnome.org/show_bug.cgi?id=771067
Similar to windows on another workspace, selecting a minimized window
doesn't look quite right - the selected window disappears, then animates
back in. Fix this by adding support for skipping the next effect to the
wm and use it to bypass the unminimize animation.
https://bugzilla.gnome.org/show_bug.cgi?id=771536
Mutter's plugin destroy event doesn't happen if a window is hidden
when it gets unmanaged so we also need to handle the
MetaWindow::unmanaged signal to check whether the parent should
dimmed.
https://bugzilla.gnome.org/show_bug.cgi?id=752524
meta_window_foreach_transient() iterates through all transients of a
window, not only direct transients. This means that simply checking if
a transient is an attached dialog isn't enough because it might be a
non-direct transient for the window we're checking, in which case we
don't want to dim the window.
In particular this fixes windows not getting undimmed when they have
more that one level of transient children and the direct transient gets
destroyed. In that case we would still find at least one non-direct
transient child and decide to keep the window dimmed.
https://bugzilla.gnome.org/show_bug.cgi?id=770163
The various switcher keybindings are handled identically, except for
the popup that is shown; update the code to reflect that instead of
duplicating the code again and again.
https://bugzilla.gnome.org/show_bug.cgi?id=730739
The code to handle cycling through windows without showing a popup
was removed from mutter a while ago, which left the corresponding
keybindings mostly broken (i.e. they now only switch between two
windows). With the various switch-foo keybindings handled by the
shell, it is now easier to take over the cycle-foo keybindings as
well.
https://bugzilla.gnome.org/show_bug.cgi?id=730739
Now that we no longer skip dimming/undimming windows while showing
the overview, we can still save a bit of work by changing the dimming
without animation while the window is hidden.
https://bugzilla.gnome.org/show_bug.cgi?id=762475
We skip window animations while the overview is shown (and the window
group is hidden) to avoid unnecessary work. However when an attached
modal dialog is opened or closed, this involves checking whether the
parent window should be dimmed - skipping that test means that we can
simply fail to dim or undim a window altogether, so do that check
unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=762475
If we get another effect on the same actor, we should make sure to
remove the clone through the "overwrite" methods provided by Tweener, or
there will be a race that might end up with a stray clone being left
around.
https://bugzilla.gnome.org/show_bug.cgi?id=756714
The translation should describe the difference between the fullscreened
and unfullscreened position of the window - however we are currently
assuming a fullscreen position of (0, 0) instead of the monitor's origin,
which causes glitches on dualscreen setups.
https://bugzilla.gnome.org/show_bug.cgi?id=756697
We use the newly introduced feature from Mutter to hook up our own
fullscreen and unfullscreen animations.
To give the illusion of a transition as smooth as possible, we create a
snapshot of the current contents of the actor before its state is
changed, and crossfade between the two states while the size changes.

Follow the design we have in gtk+ for buttons dialogs,
which are at the bottom and they expand full width, having
the same amount of space for each one.
Also, since this removes any space for non-button widgets
in the button area, move the spinner present in the auth prompt
dialog next to the password entry.

This object (not really a Clutter.GestureAction) sets up a captured-event
handler, which exclusively looks for 4 finger touchpad swipes, emitting
an ::activated signal under the same terms than WorkspaceSwitchAction.
https://bugzilla.gnome.org/show_bug.cgi?id=752250
shell_global_get_overrides_settings() may return %NULL in case of
custom shell modes (i.e. not the default and classic ones); while
this is not officially encouraged, we should still handle it rather
than throw an error.
https://bugzilla.gnome.org/show_bug.cgi?id=751921
Just reuse this gesture rather than implementing edge detection ourselves.
As a plus, we might get touchpad swipe support when Clutter handles it.

Pause dynamic workspace management while workspaceSwitcherPopup
is shown so as to eliminate infinite creation and destruction of
workspaces, thus preventing stuttering while trying to move a
window to last workspace.
Add _isWorkspacePrepended flag to make sure only a single workspace
is prepended at a time thus preventing the possibility of prepending
infinite workspaces while dynamic workspace management is on pause.
Prepend a new workspace by creating a new workspace instead of only
shifting the windows to next workspace so that the workspaceSwitcherPopup
may appear in sync with what's happening behind the scene and display
correct number of workspaces.

"Moving" a window to another workspace doesn't make sense when it cannot
be unstuck, and is potentially confusing if a new workspace is added at
the start/end - just don't do anything in that case.

Users currently can't switch VTs while at the login screen.
This commit fixes that, by adding the relevant keybindings

The code described by the comment was moved away in commit eda27d51,
so it is not misleading at best. It wasn't too useful to begin with,
so kill it off rather than moving it to the correct place ...
When using dynamic workspaces, a new workspace will be appended
when moving a window down to the last (empty) workspace. It makes
sense to extend the behavior in the opposite direction, and prepend
a new workspace when moving a window up from the first workspace.
https://bugzilla.gnome.org/show_bug.cgi?id=665764
New workspaces are inserted by shifting all windows on workspaces
below the insertion position down. As a result, when the new
workspace is inserted before the active one, we end up with
the illusion of a workspace switch. Instead, activate the workspace
on which the windows from the active one ended up.
https://bugzilla.gnome.org/show_bug.cgi?id=665764
We are not supposed to mess around with OR windows, so don't try
to shift them to a different workspace. This fixes a warning with
newer versions of mutter.

We will soon allow to insert a new workspace by other means than
DND in between workspace thumbnails, so move the relevant code
to a new windowManager method.

So that we'll recreate it the next time we want to show it. Otherwise,
we'll try to call things on a half-destroyed ResizePopup and end up
causing errors instead of showing the user their resize popup.
When animating workspace switches, windows on the old and new workspaces
are temporarily reparented. If windows are restacked, those windows will
thus be ignored by mutter until meta_switch_workspace_completed() resyncs
the stacking at the end of the animation.
As a result, activating a window on another workspace that is not on top
of the stack is very noticeably a two-step operation of switching workspace
and raising the window. There is a technical reason for that order[0], but
we can avoid the visible disruption by manually syncing the stack during
the switch operation.

Just like keybindings and the message tray pointer barrier, gestures
don't always make sense - for instance, swiping up the screen shield
should not trigger the message tray just as the SelectArea action around
the left edge should not open the overview.
To avoid this, restrict gestures based on the current keybinding mode.
https://bugzilla.gnome.org/show_bug.cgi?id=740237
Now that mutter gives a way to check if a MetaKeyBinding was marked as
'reversed' or not, gnome-shell does not have to hardcode that a
MetaKeyBinding using a shift modifier is reversed, it can directly check
if the appropriate flag is set.

The animation is the same for modal dialogs, but it is now
run for non modal dialogs too (matching the new behavior on
show).
In addition, we run a destroy animation for normal windows,
if they use CSD (there are technical limitations that prevent
running animations after destroy on server decorated windows)
https://bugzilla.gnome.org/show_bug.cgi?id=732857
Commit 6c2f3d1d17 moved pref overrides into JS to implement
session mode specific overrides in a clean and generic way.
However that approach comes with a cost - doing the overrides only
after having handled over control to JS means that the core will
be initialized with the non-overridden settings before changing
to the correct values. In the best case this is unnecessary work,
but it can in fact have a worse effect: when initializing workspaces,
we will restore the previous number of workspaces when using
dynamic-workspaces and reset to the configured number otherwise.
As the non-overridden default for dynamic-workspaces is FALSE, we
can easily end up moving the user's windows to the "wrong" workspace.
Now GSettings is expected to grow support for session specific defaults,
which will render our entire override system obsolete (yay!). Given
that, it seems acceptable to use a less generic (and uglier) approach
in the meanwhile, in order to fix aforementioned problems. So move
overrides back before core initialization and just hardcode the
session-mode => override-schema relation.
