As backgrounds are cached, it is possible that we never emit the
'loaded' signal added in commit f386103bc1. We are relying on the
signal though, so do the same as Background and emit the signal
from an idle if the background was already loaded.

(cherry picked from commit 5c550daecb)
Currently, the login animation can occur before the user's wallpaper has
been loaded. When this happens, we wind up displaying a solid blue
background for half a second or so before the proper background is
displayed. This looks jarring and bad. It's great that we can start
GNOME quickly, but starting up before the wallpaper is ready is *too*
quickly.
I've been meaning to fix this since 2014. Better late than never! We can
just have BackgroundManager emit a loaded signal the first time it loads
its first background, and have the startup animation code wait for that
before proceeding.
Some of this code is by Florian, who helped with promisifying. Thanks!

Modifying variables from an outer scope in functions created in a loop
is considered problematic by eslint, because the variable value in the
resulting closure is often not what the coder intended.
In this particular case however, the scoping is correct, so add a comment
to disable the rule locally.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.

Animation background is just wrapping a native GnomeDesktop BGSlideShow
object, so instead of using composition we can now just inherit from the
native GObject, re-using native properties when possible, and avoiding
to keep an extra wrapper to the bg file.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/563
Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/559
Meta.Background has already a 'changed' signal and not to confuse the source
signal with the wrapper one, rename the wrapper class signal into 'bg-changed'.
This will be relevant when we'll inherit from Meta.Background, as signal
emissions from the base class could interfere with the wanted derived class
behavior and with the the grouping of successive changes into a single ::change
emission.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/559
We currently use no less than three different ways of indenting
object literals:
let obj1 = {
foo: 42,
bar: 23,
};
let obj2 = { foo: 42,
bar: 23 };
let obj3 = { foo: 42,
bar: 23
};
The first is the one we want to use everywhere eventually, while the
second is the most commonly used "legacy" style.
It is the third one that is most problematic, as it throws off eslint
fairly badly: It violates both the rule to have consistent line breaks
in braces as well as the indentation style of both regular and legacy
configurations.
Fortunately the third style was mostly used for tween parameters, so
is quite rare after the Tweener purge. Get rid of the remaining ones
to cut down on pre-existing eslint errors.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/716
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:
- they run entirely in C, while Tweener requires context switches
to JS each frame
- they are more reliable, as Tweener only detects when an animation
is overwritten with another Tween, while Clutter considers any
property change
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.
Spotted by eslint.

Background is monitoring the whole `org.gnome.desktop.background` gsettings keys
for changes connecting to the non-specialized 'changed' signal and re-emitting
this as-is.
This means that when the background is changed via control-center, we get
multiple 'changed' signal events from GSettings, and for each one of this we
recreate a Background and a BackgroundActor.
Avoid this by using an idle to delay the emission of the 'changed' signal
grouping the events.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/558
The same Meta.Background could be used by multiple instances of background
actors, and so should not be disposed when the actor using it is destroyed.
Instead of calling `run_dispose` directly on it, just nullify the reference
on destroy method, leaving the job of doing the proper disposition to the
gabage collector that keeps the proper reference count on the Meta.Background.

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.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
The background code allocates a GnomeWallClock when its first created,
but neglects to drop a reference to that clock at destroy time.
The undestroyed clocks lead to a timerfd leak that eventually prevents
the shell from functioning.

Instead of potentially loading a background mid-way when it changes, and
loading it again for every file monitor event, leverage
CHANGES_DONE_HINT events, which allow us to ignore CREATED and CHANGED
signals from the file monitor.

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.

We currently reload animated backgrounds on timezone changes, but
there are other cases where the time can change unexpectedly and
the background no longer matches the time of day. One case we can
easily handle is when coming back from suspend, so do that.
https://bugzilla.gnome.org/show_bug.cgi?id=773265
The memory which MetaBackground resides is freed automatically, when its
wrapper object Background is freed by garbage collection. But because the
memory for MetaBackground is huge, changing the background or changing the
background mode repeatedly makes a lot of memory to be in use until garbage
collection runs.
This patch frees the MetaBackground object explicitly when its
MetaBackgroundActor is destroyed which is the moment that the memory in the
object is not used anymore.

Animated backgrounds are based on a start time in local time - in case
of a timezone change, that time is no longer accurate. To fix, we need
to either make BGSlideShow aware of timezone changes (and notify us to
update the animation), or just reload the animation - timezone changes
should be a rare event, so go with the simpler second option.

When loading several animations at the same time, the last call
overrides the result for all of them.
This commit caches all animations separately based on the source's
schemas.

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.

MetaBackgroundCache doesn't itself use file watches, so when a image
that we are monitoring changes we need to purge it from the cache,
so that when we load it again we get the new image.

It was assumed that BackgroundSource objects were always destroyed
on monitor changes because the BackgroundManager objects that hold
references were destroyed, but sequencing of updating of different
BackgroundManager objects meant that was not the case.
Properly update any cached Background objects held by the
BackgroundSource on a change to the monitor layout; in particular this
means updating animations in case they are multi-resolution.
