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.

The method currently catches errors that occur when calling the
extension's init() method, but throws itself an error if the
expected extension.js file is missing. The former is pointless
if we expect all callers to handle errors themselves anyway, and
we should avoid the latter if we don't - opt for the second option
and handle a missing extension.js file gracefully.
https://bugzilla.gnome.org/show_bug.cgi?id=781728
While we catch errors that occur when calling init(), enable() or
disable(), the import itself can throw an exception, for instance
if the extension imports an unavailable typelib or tries to draw
in a conflicting library.

Both reloadExtensions() and enableExtensions() are already expected
to catch extension errors. If they don't, this is the bug that
should be fixed instead of catching unhandled exceptions in the
caller.
This reverts commit ff425d1db7.

Some extensions out there may fail to reload. When that happens,
we need to catch any exceptions so that we don't leave things in
a broken state that could lead to leaving extensions enabled in
the screen shield.

When gnome-shell fails to start on login, gnome-session tries to
re-launch it again with all extensions disabled. This is currently
implemented by clearing the list of enabled extensions, which means
the user needs to re-enable their extensions manually again.
To make this process less annoying, add a single 'kill-switch' setting
gnome-session can use without interfering with the user setting.
https://bugzilla.gnome.org/show_bug.cgi?id=778664
Before reenabling all extensions, we update the list of enabled extensions
to catch any changes that happened while extensions were enabled. However
this is currently broken as onEnabledExtensionsChanged() is a nop while
disabled, so just call getEnabledExtensions() directly.
The current code only works for enabled extensions, which means
that extensions that were marked OUT_OF_DATE cannot be enabled
without a restart when disabling the version check.
Fix this by reloading all extensions while making sure to only
enable any extensions when we're supposed to.
https://bugzilla.gnome.org/show_bug.cgi?id=736185
Add a key 'disable-extension-version-validation' key that disables
the validation of extension's claimed to be supported shell version
with the shell version and just load all extensions unconditionally.

The asynchronous nature of extension loading, session loading, and more,
makes the code racy as to what is initialized first, and hard to debug.
Additionally, since gjs is single-threaded, the only code we're running
in a thread anyway is readdir, which is going to be I/O bound, so the
code here is actually likely to be faster.
Drop this in favor of some good old fashioned synchronous loading.
As currently envisioned, the fallback replacement in 3.8 should be
a separate session at the login screen. As we will use extensions
to implement this mode, we need a way to specify extensions per
session rather than per user, so add a session-mode property for
extensions that should be loaded in addition to the user-defined
ones.

St.Theme.load_stylesheet() does not queue a theme context change, so
any styling of widgets created before will not be updated. To fix this,
load the stylesheet before the extension builds its own UI in enable()

Since we eventually want to add a system for changing the top panel
contents depending on the current state of the shell, let's use the
"session mode" feature for this, and add a mechanism for updating the
session mode at runtime. Add support for every key besides the two
functional keys, and make all the components update automatically when the
session mode is changed. Add a new lock-screen mode, and make the lock
screen change to this when locked.
https://bugzilla.gnome.org/show_bug.cgi?id=683156
Use our native JS error system in the "extension system" API, only
using the signal/log-based error reporting at the last mile. Additionally,
delete the directory if loading the extension failed, and report the error
back over DBus.
https://bugzilla.gnome.org/show_bug.cgi?id=679099
Initially, extensions were loaded after they shell had fully created
the session and all objects, but this didn't allow extensions easy
ways to monkey patch prototypes, as most functions had already been
bound. Remove the historical vestigal function, and just merge the
two together.
https://bugzilla.gnome.org/show_bug.cgi?id=677586
A large amount of extensions have something like this in them:
function init() {}
Since we have encouraged extension authors to try and not make any
changes in init, it feels weird and strange to have to create an
initialization function that does nothing. From now on, don't require
it.
https://bugzilla.gnome.org/show_bug.cgi?id=677586
This allows us to move to a file-monitor based approach in the future.
Since we need signals, we convert the current set of functions to an
object we attach signals too, leading to the new ExtensionFinder object.
https://bugzilla.gnome.org/show_bug.cgi?id=677586
loadExtension() fails if the extension object is already created,
but the installation dialog was creating a dummy object in the
downloading state. Since nothing requires that (and the object is
not in the correct format anyway), just kill it.
https://bugzilla.gnome.org/show_bug.cgi?id=671134
The "extension" object is what I previously called the "helper" object.
It contains the extension importer object as well as the metadata object.
Things that were previously added on to the metadata (state, path, dir, etc.)
are now part of this new "extension" object.
With the new importer changes brought on by the extension prefs tool,
extensions are left without a way to import submodules at the global scope,
which would make them rely on techniques like:
var MySubModule;
function init(meta) {
MySubModule = meta.importer.mySubModule;
}
That is, there's now a lot more meaningless boilerplate that nobody wants
to write and nobody wants to reivew.
Let's solve this with a few clever hacks.
Allow extensions to get their current extension object with:
let extension = imports.misc.extensionUtils.getCurrentExtension();
As such, extensions can now get their own extension object before the
'init' method is called, so they can import submodules or do other things
at the module scope:
const MySubModule = extension.imports.mySubModule;
const dataPath = GLib.build_filenamev([extension.path, 'awesome-data.json']);
