Introduce a new class, EventEmitter, which implements signal
handling for pure JavaScript classes. EventEmitter still
utilizes GJS' addSignalMethods internally.
EventEmitter allows static typechecking to understand the
structure of event-emitting JS classes and makes creating
child classes simpler.
The name 'EventEmitter' mirrors a common name for this pattern
in Node and in JS libraries.

The overviewGroup's size is currently determined by the coverPane
actor. That actor is only shown during transitions, so we rely on
ClutterFixedLayout including hidden children in its size request.
That odd behavior is about to change, so we need to make sure the
overview still requests the correct size.

We currently complete the animation using an onComplete handler,
which only runs if the corresponding transition was stopped when
finished.
While it is unexpected that the transition is interrupted, it can
apparently happen under some circumstances (like VMs with qlx).
The consequences of that are pretty bad, mainly due to the cover
pane that prevents input during the animation not getting removed.
Address this by always completing the animation when the transition
is stopped, regardless of whether it completed or not.

On some hardware combinations the display can be known, then unknown again. Meaining that
when the update monitors function is called it will have a value, then be called again
setting this.primaryMonitor to null. If the timing is just right gnome shell will
loadBackground, then by the time the animation is ready the monitor will be gone,
thus methods will be called on a null value. This adds more checks for a valid
primary monitor, and wont play the animation until the system is idle AND has a valid
priamry monitor.

The changes violated too many assumptions on the mutter
side. And even if those were addressed, changing the
work area when a window enters/leaves fullscreen isn't
great, because it will force an expensive relayout on
all other windows.
This reverts commit cd1102ff30.

Start using the new methods to simplify signal cleanup. For now,
focus on replacing existing cleanups; in most cases this means
signals connected in the constructor and disconnected on destroy,
but also other cases with a similarly defined lifetime (say: from
show to hide).
This doesn't change signal connections that only exist for a short
time (say: once), handlers that are connected on-demand (say: the
first time a particular method is called), or connections that
aren't tracked (read: disconnected) at all.
We will eventually replace the latter with connectObject() as
well - especially from actor subclasses - but the changeset is
already big enough as-is :-)

We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.
But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).
And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

The new startup animation consists of rising the Dash from the bottom,
falling the search entry from the ceiling, and going from HIDDEN to
WINDOW_PICKER with an opacity applied.
One little trick from IconGridLayout was added to ControlsManagerLayout,
which is a promises-based wait for allocation. This is required to make
sure that the transformed position of the search entry is valid, which
is only the case right after an allocation.
This animation also ensures that the overview is shown right on startup.
For session modes that do not have an overview, continue using the same
fade + scale animation.

We want to avoid updating the input region on startup, since it incurs
in roundtrips to the X server, but not workspaces struts, since they
affect the visible clip of wallpapers in the workspace. Since next
commits will make the overview be the after-boot screen, we really
don't want the wallpaper to be clipped wrongly.
Allow updating regions while starting up, but only workspace struts.
Make sure input is not updated by accounting for 'this._startingUp'
on 'wantsInputRegion'.

This is an X11-specific routine, and building the list of input region rects
on Wayland is a waste, since it incurs in many trampolines only to throw them
in the trash.
Don't build input region rects on Wayland. By modifying the 'wantsInputRegion'
variable, it also skips actors that only update input, which is another small
optimization for Wayland.

LayoutManager doesn't update struts when there's any modal running. Turns
out, the Overview itself is a modal. That, and the fact that the Overview
will be the startup state, prevents the workarea to be updated.
Allow updating struts when there's no other modal than the Overview.

The animation handling is kinda split between layout (for the
keyboard slide), and keyboard (for the focus window slide). It
would be nice to have more fine grained control on those, so
move the animation handling altogether to keyboard.js as a start.
This is roughly similar, except that transformations apply to
the Keyboard actor, instead of the keyboardBox (its parent). We
now queue a relayout after the animation in order to update the
chrome tracking.
The only layering break now is that we emit
layoutManager::keyboard-visible-changed in keyboard.js, its
purpose will be dropped in future commits, so leave it there for
now.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1668>
On X11, clients can grab keyboard on pointer (for example for popup
menus), and as a result the pushModal() call when opening the overview
fails.
However when the hot corner was used to toggle the overview, we still
show the ripple animation in that case, which is confusing as the action
did not actually happen.
Fix this by only showing the ripples if the overview is animating after
calling toggle(), as that should be a reliable indication of whether
the call was successful.

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!

When using the NVIDIA driver, textures tend to loose their pixels when
suspending. In the past we handled this by figuring out when the NVIDIA
driver was used, and reload the background whenever we noticed we
resumed from suspend.
This shouldn't be needed anymore after
https://gitlab.gnome.org/GNOME/mutter/merge_requests/600, as it should
handle this by listening to video-memory-purged signal. Thus remove our
special handling here.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1358
Previously we'd show the system background and then wait till the
main loop was idle before beginning the shell startup animation.
This resulted in one initial frame that was always just the system
background.
Now we try to get both the system background and the startup animation
begun on the same first frame.

As system modal dialogs may open without user interaction (for instance
polkit or network agent requests), it is possible for them to pop up
while the app/window switcher is up.
The current result of having both up simultaneously is clearly broken,
so we can either dismiss the popup or prevent the modal dialog from
opening. Assume that the dialog indicates a more important action and
should therefore take precedence, so go with the former.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
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.

We are currently inconsistent whether to put the operators in front
of the corresponding line or at the end of the preceding one. The
most dominant style for now is to put condition and first branch on
the same line, and then align the second branch:
let foo = condition ? fooValue
: notFooValue;
Unfortunately that's a style that eslint doesn't support, so to account
for it, our legacy configuration currently plainly ignores all indentation
in conditionals.
In order to drop that exception and not let messed up indentation slip
through, change all ternary operators to the non-legacy style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/725
Since ES5, it is possible to create objects with no prototype at all:
let foo = Object.create(null);
Those object won't have any builtin properties like hasOwnProperty(),
which is why eslint added a corresponding rule to its default rule set.
While this isn't an issue that affects our code, there's no harm in fol-
lowing the recommendation and call the method through Object.prototype.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/716
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/663
For GObject properties, we follow the convention of all-lowercase,
dash-separated names. Those translate to underscores in getters/setters,
so exempt them from the newly added "camelcase" rule.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
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.
