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.

Use GLib's spawn_async() instead of Gio.SubprocessLauncher() which does
not support the child setup function to start ibus-daemon.
This way we can restore the NOFILE limit prior to run the ibus-daemon.

Commit 764527c8c9 not only ports this file
to Promises but also changes the behavior of _initPanelService method.
Instead of always calling _updateReadiness when _panelService is ready,
it only calls it when get_global_engine_async succeeds.
The only callers of _updateReadiness are _initEngines and
_initPanelService. Assume that _initEngines completes first. Its
_updateReadiness call keeps _ready as false and it is expected for
_initPanelService to change it to true. However, since
get_global_engine_async fails because there is no active engine,
_initPanelService never calls _updateReadiness. Therefore, all setEngine
calls do nothing because _ready is false, and the input method panel
never shows. Users are unable to use any input method even if they can
see that ibus-daemon is already running.
Fix the issue by changing it back to the old behavior.

Promises make asynchronous operations easier to manage, in particular
when used through the async/await syntax that allows for asynchronous
code to closely resemble synchronous one.
gjs has included a Gio._promisify() helper for a while now, which
monkey-patches methods that follow GIO's async pattern to return a
Promise when called without a callback argument.
Use that to get rid of all those GAsyncReadyCallbacks!

This (mistakenly) now only depends on signals triggered on Wayland
sessions. Hardcoding the XIM support on X11 sessions will make input
in some clients work again.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1690
The shell tries to spawn the ibus daemon on startup if unavailable, however
as per commit 8adfc5b1 we also force restarting it once the X11 server is
available.
Unfortunately this could cause a race if we disconnect while we were already
connected to an ibus daemon, but still in the process of going through the
various nested calls.
In fact the ::disconnect callback didn't stop any further async ibus call
that, even if failing, would have eventually triggered the emission of a
'ready' signal and to the Keyboard's callback, leading under X11 to a full
grab owned by ibus daemon.
In order to avoid this and keep control of the calls order, use in both
IbusManager and InputMethod a cancellable that is setup before connecting to
the bus, and that is cancelled on disconnection.
Then handle the finish() calls properly, using try/catch to validate the
returned value, taking in account the potential error and just not
proceeding in case of cancellation.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1712
We now do 2 things along Xwayland startup/shutdown:
- Start or stop the gnome-session-x11-services target, that will
pull all X11 related services that the session might depend on.
- As we start ibus-daemon manually, trigger a restart in order to
toggle the XIM daemon on and off along with Xwayland presence.

We may need to restart it with different arguments, so make it
possible to do that. Also, avoid to just restart it on _clear(),
this is now most likely through our --replace call than it is
through ibus-daemon eg. dying, avoids some noise in logs as
there is already an ongoing ibus-daemon.

Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.
We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.
So just omit braces consistently as mandated by gjs' coding style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
We are currently inconsistent with whether or not to put a space
after catch clauses. While the predominant style is to omit it,
that's inconsistent with the style we use for any other statement.
There's not really a good reason to stick with it, so switch to
the style gjs/eslint default to.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/607
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.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/361
Since commit 551e827841, we don't always pass a callback parameter.
However passing it on as undefined to ibus doesn't work, as gjs doesn't
accept that as a valid callback value and throw an error. As a result,
we can end up with no layout selected in the keyboard menu and an "empty"
indicator. Fix this by explicitly passing null if no callback has been
provided.

And stop using FocusCaretTracker for caret position purposes. This
new object uses 1) the text-input protocol in wayland and 2) Info
from IBusPanelService for X11 (which is meant to work for XIM too).
This drops the usage of AtspiEventListener for OSK purposes, which
is best to avoid.
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.

IBus was initially made optional as gnome-shell depended on too
recent API. This API is now old enough and gnome-shell is committing
further to IBus by implementing a ClutterInputMethod through it.
Let's just make IBus a mandatory dependency, instead of making code
paths trickier to cater for situations where it's missing.
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
Don't try to access a non-existent engine - it probably makes sense to
use Map() instead of a plain object to track engines in the future, but
for now just add an additional check to shut up a warning.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
Per ES6, a variable declared const should only be valid inside its lexical
scope. Previously, GJS would accept this code, but that will change in the
SpiderMonkey JS engine in the next release of GJS.

Input method preedit text needs to be disabled on password entries
for security and usability reasons.
IBus 1.5.7 provides the signal set-content-type so that panel UIs can
handle these special purpose input entries:
https://github.com/ibus/ibus/commit/6ca5ddb302c9
Unfortunately IBus versions older than 1.5.10 have a bug which causes
spurious set-content-type emissions when switching input focus that
temporarily lose purpose and hints defeating its intended semantics
and confusing users. We thus don't use it in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=730628
Normally users switch xkb input sources and ibus input sources.
But currently the first input source only is running. It's also good
to preload all ibus engines in the logging session so that users switch
input sources quickly without the launching time of input sources.
The following is the ibus change:
https://github.com/ibus/ibus/commit/cff35929a9https://bugzilla.gnome.org/show_bug.cgi?id=695428
Instead of calling out to gnome-settings-daemon we'll just implement
the switching logic ourselves and use mutter APIs that allow this
functionality to work both in X sessions and when we're a Wayland
compositor.
Switching IBus engines is done transparently as well just like g-s-d
used to do.
https://bugzilla.gnome.org/show_bug.cgi?id=736435
gnome-settings-daemon doesn't this for us anymore. Note that
ibus-daemon isn't DBus activatable but just spawning it is fine
because it does its own single instance management. The library
notifies us when it shows up and goes away through the connected and
disconnected signals.
