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.

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.

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']);
https://bugzilla.gnome.org/show_bug.cgi?id=668429
ExtensionUtils is a new module that has a lot of miscellaneous things related
to loading extensions and the extension system put into a place that does not
depend on Shell or St.
Note that this will break extensions that have with multiple files by replacing
the old uuid-based importer with an object directly on the meta object.
https://bugzilla.gnome.org/show_bug.cgi?id=668429
If an extension fails to import, we will pass the error object
to logExtensionError, which fails to pass it onto DBus as an
error object is not a string. To fix, convert the error object
to a string before passing it to logExtensionError.

When installing an extension at runtime, we accidentally swapped the 'type'
and 'enabled' parameters. While this doesn't directly affect anything right
now, as everything works coincidentally, future patches that look at the
'type' parameter to decide what to do would get the wrong answer.
When two extensions monkey-patch the same area, enable() and disable() may
behave badly and completely wreck things. To solve this, when disabling
an extension, "rebase" the extension list so that monkey patches should be
added and removed in order.
https://bugzilla.gnome.org/show_bug.cgi?id=661815
Rather than loading and enabling all extensions at Shell init time, save some
time and gain some basic security by not loading extensions if they're
not enabled.

js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.
