Besides the device grab on the drag device, also set up a captured-event
handler to catch other devices (except the keyboard) while the DnD
operation is ongoing. This makes DnD operations exclusive to others.
Also, disallow it in less aggressive ways if maybeStartDrag() gets called
while there is a current draggable.
This might definitely be nicer (eg. having other grabbed devices emit
leave/end events), but can't be done without major surgery to Clutter.
In the case where the draggable has an actor of its own, state could be
left broken when dragging on a place that would not accept the DnD op.
After button release, drag state is set to "cancelled" and the animation
begins. After the animation is finished, the drag actor would be destroyed
before disconnecting from its destroy handler.
Within the destroy handler, the grab would be undone but drag state would
be left on "cancelled" state for subsequent operations. This results in
DnD oddities and stuck grabs.
In order to fix this, double check in the actor destroy handler that we
are actually dragging before setting the "cancelled" state.

Instead of fetching the CLUTTER_POINTER_DEVICE device. It will
be wrong if drags get initiated from tablet pointers. This allows
for DnD operations to be started, moved, and more importantly
finished through tablet devices.

Whenever the AllView needs (re)populating, we used to do one general
g_app_info_get_all() to get all GAppInfo, plus one per app folder in order
to check the ones that fall within that category. This calls results in a
fair amount of I/O blocking the main loop.
In order to ease this, keep the GAppInfo list around in AllView, and make
the AppFolders use it when figuring out the contained apps. Since reloading
the AllView results in AppFolders regenerated from scratch, the app info
list is ensured to be up-to-date for any later change within the AppFolder
(eg. through the GSettings key changing).
As the list was already filtered in the first place, we can also remove
the try{}catch() in AppFolder in order to discard desktop files with
invalid encoding.

ES6 finally adds standard class syntax to the language, so we can

When using dynamic workspaces, it is possible to try to change to a
non-existent one if the user defines hotkeys for changing to desktop
1, 2, 3... This case is not detected, and gnome shell shows an error:
JS ERROR: TypeError: workspace is null

This patch adds a check before trying to change the workspace, to avoid
switching to a non-existent one.

When an InputSourceIndicator is destroyed, the InputSourceManager it was
connected to could (and probably will) outlive it (since the manager is
a singleton). If the InputSourceManager emits any subsequent signals,
the callbacks from the finalised InputSourceIndicator could be invoked,
and will reference finalised objects.
This can be triggered by running `pkexec true` from a gnome-terminal
window, then calling `pkill pkexec` from another terminal (on a
different VT or via SSH). This causes the dialogue to be cancelled by
polkitd.

Otherwise the user object could outlive the dialogue, emit a subsequent
signal, and the callback from that signal could reference finalised
objects/widgets from the dialogue. The likely mechanism for the user
outliving the dialogue is caching of user objects within
libaccountsservice.
This can be triggered by running `pkexec true` from a gnome-terminal
window, then calling `pkill pkexec` from another terminal (on a

Rather than explicitly destroying the session after calling close(),
destroy it from the `closed` signal handler.
This also means we can make the method internal.

In case there are any internal ways the dialogue can close itself
without calling its own close() method, it’s probably better to do all
our cleanup on a handler for the `closed` signal instead.
This should introduce no functional changes except ensuring the
polkitAgent cleanup is always done.

Otherwise the session could outlive the dialogue, emit a subsequent
signal, and its callback would reference finalised objects/widgets from
the dialogue. The PolkitSession object is implemented by
libpolkit-gobject, so we have no guarantees about its reference counting
— the session object could keep itself alive in another thread, or be a
singleton. In all likelihood, the session hangs around for longer than
the dialogue due to differences in when the two objects are garbage
collected.
This can be triggered by running `pkexec true` from a gnome-terminal
window, then calling `pkill pkexec` from another terminal (on a

The built-in calendar isn't meant to replace a full-fledged calendar
app, which is why clearing event messages only hides the event in
gnome-shell rather than deleting the actual event. This has turned out
to not be overly useful and often confusing - it creates a discrepancy
with visible events in apps, isn't revertible in a non-obscure fashion
and non-obviously limited to the current date.
As we are considering moving events out of the message list and back to
the calendar, it looks like a good time to remove that ability and keep
notifications as the only removable messages.

We currently deliberately avoid chaining up in derived policy
constructors to not override properties with their defaults.
That's a neat trick that will stop working when porting to ES6
classes, as chaining up is necessary to actually initialize the
object there (including "this").
Address this by turning all properties into (overridable) getters
that are backed by private properties by default.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/350
The _createPolicy() method of a subclass usually depends on some
constructor parameters that need to be set before chaining up to
the parent. This works fine with Lang.Class, but will break with
ES6 classes, as "this" is only initialized after chaining up.
Prepare for this by not creating the policy in the constructor,
but when it is first accessed.

Check via Polkit if the current user is actually allowed to enroll
devices before trying to do so. If not, show a notification that
explains that a system administrator needs to authorize the device.
Clicking on the notification will guide the user to the thunderbolt
control center panel. Before this patch, when the current user was
not allowed to enroll a device a polkit dialog would pop up which
is confusing because it did not contain any information why it was
shown. This patch implements the behavior as designed (see [1],
section "Multi-user environments").

Since commit 5fb8d4f730, a NotificationMessage's notification property

to disconnect later.

the same time as the notification.

The picked target actor may be destroyed (e.g. hover style change
resulting in the ClutterTexture to be destroyed). If we don't handle
this, GJS will abort when it sees the exception caused by Javascript
code trying to access the destroyed target actor.
To handle it, listen on the 'destroy' signal on the target actor, and
repick, so a valid actor is passed to the next motion callback.

When a fullscreen application is focused,
toggling the overview via hot-corner is disabled,
even when the overview is currently visible.
This only makes sense, when the overview is
hidden to not to disturb the behaviour of the
fullscreen application, but leaves an
inconsistency when the overview is visible since
it should work there like when a non-fullscreen-
application is focused.
So, always allow hiding the overview using the
hot corner when the overview is visible.

The intention of commit 4dc20398 was to disable unredirection while
banners are shown, but the ::done-displaying signal currently used for
re-enabling unredirection is only emitted under some circumstances, so
it's possible that unredirection is left disabled indefinitely, whoops.
Fix this by tying disabling unredirection explicitly to the lifetime
of the banner actor.

The only reason for `vfunc_paint` and `vfunc_pick` existing was to
implement a culling optimization. Although that optimization actually
made performance worse than none at all because it forced the painting
and picking cycles to spend more time calling into JavaScript.
Turns out we don't have to choose between native code and culling though.
Just reimplement the culling using native ClutterActor functions and we
get the benefits of both.

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

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.

Back in the day, there was a proposed system of tracking apps in a
specific context.
The inspiration was that you may have used apps in multiple modes:
Firefox may have been used in both "Programmer Reference" and
"Kitten Videos" contexts. Early user response to the feedback wasn't
too positive - context switching is something that humans have trouble
doing implicitly, let alone explicitly. The old codebase still has a
few remnants of this around; let's finally put them to rest.
Note that we still write out a dummy context tag to the XML file - old
versions of the shell will flat out crash if you don't have one of those
in there, so just leave it in for compatibility sake.
