environment: Fix transition callback
This is rather embarrassing - we currently confuse the transition with
the finished parameter, which means we always run the onComplete handler
no matter whether the transition was interrupted or actually completed.
Commit 0f178c3b3dcfe added a shortcirtuit to avoid running
an animation on an invisible actor. However, it introduced
a bug where the current page is not properly updated. That
leads to the wrong set of icons being animated under some
circumstances.
Update the current page even if we bail out early.
Properties that aren't marked as animatable don't support *implicit*
animations, but they can still be animated with explicit transitions.
Use the newly added convenience method to cut down further on Tweener
usage.

environment: Add convenience method for property transitions
While we are now using implicit animations for all animatable properties,
there are still some cases where we animate other actor properties (for
example from a custom subclass) or associated objects like effects.
Those can still be animated using Clutter animations, as long as we use
the explicit API rather than implicit animations. Again this API is
cumbersome and tricky enough to warrant a convenience wrapper.
js: Use GObject properties for animated properties
Clutter animations work on GObject properties on animatables. The
last commit took care of the latter by turning all animated objects
into actor subclasses, now it's time to make all properties used
in Tweens into GObject properties.
We have a couple of places where we don't tween the actor, but a
custom property on the delegate object. In order to move those
to Clutter animations, we will need an animatable, so turn those
objects into widget subclasses.
The set_brightness() method is the most convenient way of controlling
the effect's brightness, but Clutter animations only deal with properties,
so start using the (ClutterColor) brightness property instead.
Currently WindowDimmer exposes a JS property that is used to control the
underlying effect. This works fine with Tweener, but not with Clutter
animations which we want to use ultimately.
As a first step towards that, expose a setDimmed() method instead of
the property and handle the animation internally, so it can be adapted
more easily.

environment: Add convenience method for implicit animations
Setting up implicit animations is more verbose than using tweener, in
particular when setting up a callbacks to run on overwrite or completion.
In order to make its use more convenient, monkey-patch ClutterActor
with an ease() method that works similarly to Tweener.addTween().

environment: Support slow down factor when easing
Being able to slow down animations is a helpful debugging tool; to not
lose it when starting to use Clutter's implicit animations, monkey-patch
the appropriate methods to support our global slow down factor.

environment: Add adjustAnimationTime() helper
As we currently use Tweener for all animations, we have a single place
for hooking up the enable-animations and slow-down-factor settings.
However that will no longer hold true when we'll start to use Clutter's
built-in animation facilities, so add a small helper function that
applies the necessary adjustments.
Notifications use a transition that overshoots the target value, however
we can only really do that for the position and not the opacity where
some values would end up out of the valid range.
We currently address this by proxying the actual opacity property in a
javascript property, and clamp it to the valid range in an onUpdate()
callback.
This won't be an option if we want to use Clutter animations, so instead,
use separate tweens for opacity and position.
Florian Müllner [Sun, 4 Aug 2019 23:02:38 +0000 (01:02 +0200)]
pageIndicators: Defer IN animation until redraw
Unlike Tweener, which doesn't know or care about actor state, Clutter
will skip implicit animations on actors that aren't mapped. This makes
sense of course, but it will break the page indicator animation we
do on map: When we get notified about the container being mapped, the
individual indicators (which are the actors being animated) are still
unmapped.
Resolve this by deferring the animation to a LaterFunc.
For animating the arrows on the screenshield, we currently use a custom
transition function that tweens the opacity from 0 to maxOpacity in the
first half of the animation, and from maxOpacity back to 0 in the second
half.
This doesn't easily translate to Clutter's own animation framework, so
replace the custom transition with two consecutive tweens which do.
Dash items are currently animated via the custom "childScale" and
"childOpacity" properties. However since commit efb3025d8cdb, those
properties actually control the scale-x/scale-y and opacity properties
of the actor itself (not the child), so cut out the intermediate
custom properties in favor of the "real" ones.

popupMenu: Split submenu expansion and arrow rotation
When expanding a submenu, we currently use a single tween to animate
both the submenu actor and the source arrow. We do this by tweening
a monkey-patched JS property on the main actor, which we then use
to update the arrow's GObject property on updates. As Clutter cannot
animate random JS properties, this trick will prevent us from using
implicit animations here.
The only reason I can think of for using a single tween is to keep
both animations in perfect lock step, but as expansion and rotation
are visually quite distinct, this shouldn't be required, so just
set up separate animations for each actor.

shell-app: Consider desktop actions in can_open_new_window()
We currently only consider a remote "app.new-window" action when running,
but not a fixed "new-window" action in the .desktop file. The latter is
clearly useful as well, in particular as open_new_window() already does,
so add it.
We start with a dim factor of 0, so the syncEnabled() call in the
constructor will always disable the effect. Just create the effect
disabled and save the method call.
barLevel: Don't reset value on overview-start changes
While it makes sense to cap the current value to a new maximum value,
I can't think of a good reason why changing the overdrive-start should
reset the current value to that.
The time computation isn't just unnecessary in that case, it's likely
wrong as well: If we don't have a valid allocation, we may well end
up with a negative value, NaN or Infinity.
Now that redisplaying is a lightweight operation that only
adds and removes what changed, we can not be concerned about
redisplaying on folder changes.
Redisplaying will be necessary when custom order in the app
grid is implemented, in order to update not only which icons
are hidden, but also their position.
FolderView and AllView currently check if the item is
present in the BaseAppView._items map, in order to avoid
adding the same icon multiple times.
Now that BaseAppView._loadApps() has a different role --
it returns a list with all app icons, and BaseAppView
diffs with the current list of app icons -- checking the
BaseAppView._items map is wrong.
Make sure there are no duplicated items in the temporary
array returned by all _loadApps() implementations. Remove
the now unused BaseAppView.hasItem() method.
BaseAppView currently removes all icons, and readds them, every
time the list of app icons needs to be redisplayed. In order to
allow animating app icon positions in the future, however, we
cannot destroy the actors of the app icons.
Previous commits paved the way for us to do differential loading,
i.e. add only the icons that were added, and remove only what was
removed.
Make the BaseAppView effectively implement differential loading.
The BaseAppView.removeAll() method is removed, since we do not
remove all icons anymore. BaseAppView._loadApps() now returns an
array with the new apps, instead of putting them directly at the
BaseAppView lists.
Now that the three views follow the exact same loading routine
(remove all + load apps + load grid), we don't need each view
call loadGrid() directly anymore.
This is an important step in order to animate adding and removing
icons, since now we can diff old and new app icons properly.
Move all calls to BaseAppView.loadGrid() to a single one after
BaseAppView._loadApps(). Also add the underscore prefix, since
this is now considered a protected function.
frequentView: Use BaseAppView.addItem() and loadGrid()
FrequentView is another view that is slightly not unified with how
BaseAppView expects subclasses to load app icons. Instead of using
BaseAppView.addItem() and then calling BaseAppview.loadGrid(), it
adds the app icons directly to the icon grid.
Make FrequentView add icons using BaseAppview.addItem(), and load
the icons using BaseAppView.loadGrid().
Future patches will diff the old and new icons of views, in order to
animate them when necessary (e.g. adding an app icon to a folder, or
from a folder back to the app grid). In order to do that, all views
must be streamlined in how they load app icons.
Currently, FrequentView and AllView are already following the behavior
expected by BaseAppView, but FolderView isn't. Its icons are loaded by
FolderIcon, and FolderView doesn't implement BaseView._loadApps(),
which makes it impossible to diff old and new apps.
Move the app icon loading routine from FolderIcon to FolderView, by
implementing the _loadApps() method.

timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's

particular where constants are shared between modules.
In order to prepare for the transition, define all animation times

data: Flag in desktop file that gnome-shell can be started using systemd
As gnome-shell is a required component for GNOME sessions, gnome-session
will currently always try to autostart it. However as we are moving towards
using systemd's user instance for session startup, gnome-session should only
be responsible for launching the shell when either not running under systemd
or when we were built without systemd support.
gnome-session can detect the former but not the latter, so communicate this
via the newly added X-GNOME-HiddenUnderSystemd key in the .desktop file.
Our current Weather integration depends on poking around the app's
settings, which we cannot do when the app is sandboxed (as its
filesystem is "hidden away" in a container in that case).
So instead, use our own GSettings schema for the settings, and sync
it with GNOME Weather via a custom D-Bus interface.
`g_object_notify()` actually takes a global lock to look up the property
by its name, which means there is a performance hit (albeit tiny) every
time this function is called. For this reason, always try to use
`g_object_notify_by_pspec()` instead.
We currently assume that user icons are square, which is the case when
set by the users settings panel, but not enforced by AccountsService.
Handle that case by moving the pixel size back to the actor and using
an appropriate background-size style property of 'cover' (which means
the smallest dimension of the image is scaled to fit the desired size).
A generic, introspectable Shader effect is not only more flexible
than a shader actor, it will also make it much easier to turn
Lightbox into an actor subclass and replace Tweener with Clutter's
own animation support.

The check is supposed to run for all merge requests that touch javascript

AppIcon makes itself draggable, and handles the various DnD
routines such as 'drag-begin' and 'drag-end' by making the
Overview emit the appropriate signals.
However, when destroyed, the AppIcon does not try to finish
any drag operations that started. That causes the event
blocker in AllView not to be updated correctly when dragging
icons to outside folders.
Make AppIcon emit 'item-drag-end' when a drag operation
started and it's destroyed.

ci: Add eslint job to review stage
We have now reduced the number of eslint errors enough to add it to

cannot simply run eslint and fail on any errors. So instead, run it

- generates an eslint report using the "regular" configuration
- generates an eslint report using the "legacy" configuration
- creates a combined report with errors common to both configurations
When the pipeline is running for a branch or tag, the final report is
printed out and the job succeeds (we know there are errors left);
when the pipelne is running for a merge request, we fail if any errors
are reported for the lines modified/added by the MR.
GNOME apps use 'review' for the CI stage that generates and exports a
flatpak bundle after a successful build, so they need some other name

use that for all checks that are performed before the build stage.
