When determining the biggest icon size that fits the available height,
we first subtract the additional space requirements of icons (spacing,
padding, running indicator etc.) and then divide the result by the
number of icons to get the maximum size available to each icon texture.
In the above, the additional space requirement of each icon is taken
from the first icon (as all icons are assumed to be the same), and
calculated as the difference between the icon button's preferred height
and the currently used icon size.
To make sure that the icon is actually using the dash's current icon
size (even while animating to a new icon size), we enforce its height
during the size request and restore its original height afterwards.
However after some recent changes, that step is causing troubles:
For some reason, the original height may be 0, and when we restore it,
we end up forcing a fixed non-height that bypasses the regular size
request machinery.
While it is unclear where exactly the zero height comes from (maybe
waiting for a valid resource scale?), it is clear that it's best
to avoid forcing a fixed height. So instead of making the icon
texture comply with the assumed icon size, adjust the calculations
to use its current height request.

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.

Destroy the DashItemContainer's child from the same handler as the tooltip. This
will prevent invalid reads when the item is destroyed while its quicklist is
still open.
Fixes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/781
DashItemContainer currently animates the scale and opacity
of its child when zooming in. This is visible when adding
a new favorite item to the dash; the items will zoom in from
the center.
After the previous commit, however, the zoom animation got
slightly broken, and looked like the icon was coming from
the bottom instead of the center.
Fix that by setting the scale and opacity of DashItemContainer
itself, instead of its child. Remove the unused code after that
too.

Pretty much like the previous patches, this extends St.Bin. The
most interesting aspect of this patch is that most of the sizing
routines of the icons is now delegated to the actors and layout
managers, removing quite a bunch of code.
The 'spacing' theme property is now redirected to StBoxLayout's
spacing property. Also adjust the Dash code to stop forcing a
potentially invalid width in the first icon too.

Flag some actors that are good candidates for caching in texture memory
(what Clutter calls "offscreen redirect"), thereby mostly eliminating
their repaint overhead.
This isn't exactly groundbreaking, it's how you're meant to use
OpenGL in the first place. But the difficulty is in the design of
Clutter which has some peculiarities making universal caching
inefficient at the moment:
* Repainting an offscreen actor is measurably slower than repainting
the same actor if it was uncached. But only by less than 100%,
so if an actor can avoid changing every frame then caching is usually
more efficient over that timeframe.
* The cached painting from a container typically includes its children,
so you can't cache containers whose children are usually animating at
full frame rate. That results in a performance loss.
This could be remedied in future by Clutter explicitly separating a
container's background painting from its child painting and always
caching the background (as StWidget tries to in some cases already).
So this commit selects just a few areas where caching has been verified
to be beneficial, and many use cases now see their CPU usage halved:
One small window active...... 10% -> 7% (-30%)
...under a panel menu........ 23% -> 9% (-61%)
One maximized window active.. 12% -> 9% (-25%)
...under a panel menu........ 23% -> 11% (-52%)
...under a shell dialog...... 22% -> 12% (-45%)
...in activities overview.... 32% -> 17% (-47%)
(on an i7-7700)

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.

Since commit ef1e27966d turned DashItemContainer into an StWidget,
the destroy() method overrides the ClutterActor method, which is at
the very least bad style. Instead, follow the usual pattern of using
a ::destroy handler.
https://bugzilla.gnome.org/show_bug.cgi?id=791233
Labels are currently destroyed from both animateOutAndDestroy()
and destroy(), which now (rightfully) triggers a gjs warning. As
the label is created unconditionally since commit 36e5ae4a25,
mirror that and always release it in destroy() and hide it
elsewhere.
https://bugzilla.gnome.org/show_bug.cgi?id=791233
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
We currently use "array[index]" to test whether an array has an
element at index before using it. However nowadays gjs warns about
accessing non-existent array elements, so the test itself already
produces a warning. Avoid this by checking the array length before
using an index to access an element.

StIcon will skip loading the texture when its theme node is unset (which
may happen on style changes while the widget is hidden). While our size
request to compute the dash icon size will create the icon's theme node
if necessary (and of all its parents), a missing texture can still throw
off our computation.
Make sure this doesn't happen by ensuring the icon's style first, so the
texture is updated in response to StWidget::style-changed if necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=745649
When adjusting dash icon sizes, we compute the icon padding by subtracting
the configured icon size from the first icon actor's preferred size. To
make sure that the preferred size correctly corresponds to the current
dash icon size even while the icon is animating, we enforce the size
before the size request. For that we used to temporarily manipulate
the icon texture size directly, but commit e92d204d42 cleaned this
up to use the setIconSize() method instead.
This does not work however, as the icon actor's iconSize property will
always match the dash iconSize property, making the method a noop. So
go back to the original approach of enforcing the texture size to make
sure we always base our computations on correct values.

The overview has a longer life-time than dash items, so we are

Because there's nothing (in single-monitor setups) that could

In a lockdown scenario, where the favorite-apps GSettings key is not
writable, hide the menu items for adding and removing favorites from the
dash menu. Additionally, reject drops to the dash for DND.
https://bugzilla.gnome.org/show_bug.cgi?id=741325
When the dash does not contain any applications (either favorites
or running), it is currently impossable to add a favorite via DND.
Grow the dash slightly in that case to provide a drop target.

We currently only keep track of old placeholders when moving past
the dragged app's current favorite position, as this is the only
case where we need to worry about jitter. Still, moving it into
_clearDragPlaceholder() allows us to consolidate code paths, which
is a good thing ...
https://bugzilla.gnome.org/show_bug.cgi?id=684618
The function currently only resets the placeholder position if
there is a placeholder; this is not necessarily true, as the
placeholder may be reset outside _clearDragPlaceholder().
If this happens, the placeholder will temporarily stop working
for the "old" position (and permanently if it's the only position).
Just reset the position unconditionally.
https://bugzilla.gnome.org/show_bug.cgi?id=684618
animateIn and animateOut should not reset the scale, otherwise
extra animate calls (which are possible because the diff algorithm
in _redisplay is not optimal) cause unneeded movement.
Therefore, create new items hidden, and have the creator call
animateIn or set the scale/opacity properties manually.
adjustIconSize must be changed to always set the icon size temporarily,
otherwise the first time it computes the icon size with 0 scale.
https://bugzilla.gnome.org/show_bug.cgi?id=690643
The DashActor will known to allocate the show apps button only if the
icon size is (temporarily) too big for the containing box, therefore
it should request just that as the minimum size.
This solves a glitch that happened when removing a favorite and at the
same time causing the dash to expand.
https://bugzilla.gnome.org/show_bug.cgi?id=690643
AppIcon is just a tiny wrapper around BaseIcon, which does not add
anything over using BaseIcon directly, so merge its code with
AppWellIcon. As the concept of the "app well" has not been used
since well before 3.0, use AppIcon as name for the merged class.
https://bugzilla.gnome.org/show_bug.cgi?id=694192
When updating the dash, we already avoid all animations while the
overview is hidden. However, as we are using Main.queueDeferredWork(),
updates may be deferred up to ~20 seconds while the overview is hidden.
If the overview is entered before a queued update has taken place, it
will be run immediately on map - as the overview is visible by then,
this means animating any outstanding changes.
Work around this by skipping animations during overview transitions as
well.
https://bugzilla.gnome.org/show_bug.cgi?id=686530
When in the overview, if you move the mouse cursor over one of the
application launchers in the dash, all the unrelated windows are dimmed
both both in the window view and in the workspace view.
It helps to easily understand whether or not there are already opened
windows for this application, and where they are. It can also help in
differentiating the windows in the overview (sometimes the thumbnails
aren't precise enough to easily know which thumbnail belongs to which
application).
https://bugzilla.gnome.org/show_bug.cgi?id=657315
This has also the benefit of getting the application even if it can not
be retrieved through AppSystem, which can happen if the runtime WMClass
does not match the one of the desktop file.
This especially looked wrong with the following commits related to the
bug.
https://bugzilla.gnome.org/show_bug.cgi?id=657315
We simply hide the label when the popup is opened instead of relying
on the popup state when the hover state change.
To do this we replace the flag isMenuUp by a 'menu-state-changed' signal
on the AppWellIcon. This simplifies the dash label visibility handling
code that need additional changes for the bug.
https://bugzilla.gnome.org/show_bug.cgi?id=657315
After some changes, the tooltip label at the dash is not available
until it is visually shown. As this is not anymore a reliable
source of accessible name, we just set the accessible name
with the string used on that label.
https://bugzilla.gnome.org/show_bug.cgi?id=686583
Currently the label for the show-apps button is only updated during
drag operations, so after an item is successfully dropped on the
button, the label will still read "Remove from Favorites".
Fix this by resetting the label on drag-end.
https://bugzilla.gnome.org/show_bug.cgi?id=684627
Having the tooltip change when it's visible looks strange and glitchy.
This also makes sure that "Remove from Favorites" doesn't change, even
when the user removes their mouse cursor from it.

When Florian landed the new dash container to show the all apps button
always, he got the math wrong -- he forgot to add padding around the
container, and used the height of the box to calculate a y2 position,
rather than the y2 position of the box.
https://bugzilla.gnome.org/show_bug.cgi?id=684619
When the dash contains more icons than fit at the minimum icon size,
icons are cut off at the end. This means that the show-apps button
will be the first to disappear, which is problematic given it's the
sole access point for other applications (for those that refuse to
use search at least).
Fix by using a dedicated widget for the dash actor, so that in case
of underallocation only icons above the show-apps button end up being
cut off.
https://bugzilla.gnome.org/show_bug.cgi?id=683340
We pass the dash’s showApps button to the viewSelector, and we connect it
to the showing and hiding of the appsView. This is necessary because there
are different mechanisms for switching the views, and it has to stay in
sync with the button’s state.
https://bugzilla.gnome.org/show_bug.cgi?id=682109
In the new designs, we no longer need favRemoveTarget. As it shares a lot
of its functionality with the new showAppsIcon, we refactor and restyle it
accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=682109
We’ll be repurposing the favRemoveTarget, which calls for it the be
permanently visibe. The favRemoveTarget used to be added to the dash when
needed and removed again when it wasn’t. This made that it always appeared
at the bottom of the dash. Now that we always show it, we also need to
explicitly define it to be at the bottom of the dash.
https://bugzilla.gnome.org/show_bug.cgi?id=682109
We are currently taking "old" placeholders that are still animating
out into account to calculate the new placeholder position - this
causes an annoying bug, where dragging a dash item downwards triggers
quick continous position changes of the placeholder.
Just ignoring old placeholders fixes the issue.
https://bugzilla.gnome.org/show_bug.cgi?id=651842
Running apps are always kept in the dash, so removing them from
favorites just moves them to the end of the favorites list. This
behavior is not immediately obvious, so only show the remove target
when dragging a favorites application that is not currently running.
https://bugzilla.gnome.org/show_bug.cgi?id=644853
We consider spacing and padding in _adjustIconSize, but as we use

The current code uses the dash's height and current icon size to
calculate the new icon size. However, the height does not correctly
relate to the icon size while the icons are animating, in which
case the resulting icon size may be wrong.
Rework the function to be independent from the actual icon sizes,
so that a correct size is calculated even when called during an
animation.

This patch fixes the "apps vanish from alt-TAB bug".
If a "package system" rips away and possibly replaces .desktop files
at some random time, we have historically used inotify to detect this
and reread state (in a racy way, but...). In GNOME 2, this was
generally not too problematic because the menu widget was totally
separate from the list of windows - and the data they operate on was
disjoint as well.
In GNOME 3 we unify these, and this creates architectural problems
because the windows are tied to the app.
What this patch tries to do is, when rereading the application state,
if we have a running application, we keep that app around instead of
making a new instance. This ensures we preserve any state such as the
set of open windows.
This requires moving the running state into ShellAppSystem. Adjust
callers as necessary, and while we're at it drop the unused "contexts"
stuff.
This is just a somewhat quick band-aid; a REAL fix would require us
having low-level control over application installation. As long as
we're on top of random broken tar+wget wrappers, it will be gross.
A slight future improvement to this patch would add an explicit
"merge" between the old and new data. I think probably we always keep
around the ShellApp corresponding to a given ID, but replace its
GMenuTreeEntry.

The dash object is currently exposed as a public object.
It's only used outside of the overview for the dash object's

iconSize property to the overview.

This dramatically thins down and sanitizes the application code.
The ShellAppSystem changes in a number of ways:
* Preferences are special cased more explicitly; they aren't apps,
they're shortcuts for an app), and we don't have many of them, so
don't need e.g. the optimizations in ShellAppSystem for searching.
* get_app() changes to lookup_app() and returns null if an app isn't
found. The semantics where it tried to find the .desktop file
if we didn't know about it were just broken; I am pretty sure no
caller needs this, and if they do we'll fix them.
* ShellAppSystem maintains two indexes on apps (by desktop file id
and by GMenuTreeEntry), but is no longer in the business of
dealing with GMenuTree as far as hierarchy and categories go. That
is moved up into js/ui/appDisplay.js. Actually, it flattens both
apps and settings.
Also, ShellWindowTracker is now the sole reference-owner for
window-backed apps. We still do the weird "window:0x1234beef" id
for these apps, but a reference is not stored in ShellAppSystem.
The js/ui/appDisplay.js code is rewritten, and sucks a lot less.
Variable names are clearer:
_apps -> _appIcons
_filterApp -> _visibleApps
_filters -> _categoryBox
Similarly for function names. We no longer call (for every app) a
recursive lookup in GMenuTree to see if it's in a particular section
on every category switch; it's all cached.
NOTE - this intentionally reverts the incremental loading code from
commit 7813c5b93f. It's fast enough
here without that.
