Calling g_dbus_proxy_new without any flag means that the caribou
daemon will be launched through D-Bus activation, when creating

but generally it would be good to avoid creating unused process.
This patch delays the invocation until the "Run" method is called.

Splits instantiation of the event source into a separate method,

There is currently no simple way to inject into AppIcon's state change,
so an extension that wants to do this has to destroy/remove/update all
icons in the Shell (i.e. in the Dash, AllView, FrequentView) on enable()
and disable() after updating AppIcon.prototype._onStateChange, or the
extension must require a restart of the Shell.
To solve this issue, we rename _onStateChanged to _updateRunningStyle,
and connect the notify::state signal with an anonymous function that
calls _updateRunningStyle.
This extra function call should allow extensions to just extend the
updateRunningStyle function in the prototype.

With commit dc6a60dde, the calendar displays the ending day and time of
a continuing multi-day event on its ending day. This results in the list
not appearing to be sorted. This patch sorts the list according to the

With the two appointments
Thursday 0800-1000 Foo, and Wednesday 0900-Friday 1200 Bar and today
being Monday, the rest of the week list currently displays:
F ...1200 Bar
T 0800 Foo
With this patch, the displaying order is switched because Friday comes

Currently, multi-day events are shown as individual appointments on each
day. This patch ellipsizes multi-day events to indicate continuation on
the prior or following day (or other time-period.)
The time label spot is now replaced by a box layout that contains the
prefix ellipsis label, the time label and the postfix ellipsis label.
In order to keep the alignment, ellipses are merely invisible (zero
opacity) when hidden.
The ellipses are styled using the events-day-time-ellipses class which,
by default, take the color of the event text.
When RTL is used, the box contents are adjusted accordingly (clutter
does that for us).
An event spanning three days now displays "...All Day..." in the
calendar on the second day.

It is really annoying for the user to acknowledge multiple notifications
when they queue up. So, to prevent a notification flood that has to be
handled by the user one-by-one, a summarized-notification feature is
added which leaves a single summarized-notification for the user,
replacing multiple notifications if the number exceeds 1, which they may
or may not acknowledge. When this summarized-notification is acknowledged,
the message-tray is opened where they can view the notifications that were
summarized. This helps the user concentrate on his primary task
simultaneously informing them about the new notifications.

We commonly mark strftime format strings for translation to account
for date/time representations without an existing strftime shortcut
("Yesterday %H%p"). As those translations are looked up according to
the locale defined by LC_MESSAGES, while the conversion characters
themselves are resolved according to LC_TIME, the result can be
rather odd when mixing locales ("Den 27. January"). The correct
solution would be to install translations for format strings in
the LC_TIME catalogue and look them up with dcgettext(), but we
don't have the infrastructure to do that easily. Work around this
by adding a helper method that looks up a string in LC_MESSAGES
using the locale defined by LC_TIME and use that to translate
format strings, which has the same result.

Most of the code handles the sources setting being empty and
InputSourceManager.currentSource being null because previously the

empty or contains only invalid entries. Adding the default keyboard

Commit a4475465f1 fixed the wrong alignment for the fully visible

align them with the corresponding edge is always 0. It's controls

When the keyboard is destroyed, we destroy the keyboard actor, but the

The spring animation has to use clones to escape any clip set on the

Can't wait to double the size of this list when these start using D-Bus
activation.
These were actually renamed in GNOME 3.12, but we couldn't do anything
about it before, and now we can.
It was assumed that BackgroundSource objects were always destroyed
on monitor changes because the BackgroundManager objects that hold
references were destroyed, but sequencing of updating of different
BackgroundManager objects meant that was not the case.
Properly update any cached Background objects held by the
BackgroundSource on a change to the monitor layout; in particular this
means updating animations in case they are multi-resolution.
All other submenus link to the corresponding settings, so we should
do the same for location - the privacy panel in this case, which now
sports a "Location Services" switch ...

This lets us considerably clean up the event flow here and change how
things are structured. It also makes sure that we never show "No
Results" -- search.js not being aware of the timeout means that it might
not think that any work was being done when we show the page.
Keep a flag depending on whether a provider is in-flight, and use that
to determine what status label to show.
This ensures that we only show "No Results" when we're done searching
and we're sure that all providers have returned results back to us.
The complexities of tracking these two things separately, with the
display on one half, and the searching on the other half, is difficult
to manage. Squash it all together.
It is quite weird to have those calls/signals using WindowClone as an

And use it to lookup the local WindowClone that applies. Otherwise,
WorkspaceThumbnail.WindowClone objects may be mistakenly set, which

may lead to several misbehaviors as fields available in the second

values get used in math ops, which result in NaNs over the place.

now MetaWindow arguments too.

Currently we consider the last item animating being the last actor of
the list, but that's wrong since the last item animating depends on the
distance between the source actor and the original position of the
animated actor.
Take that into account to check the last item of the animation.
The code that cleaned up when a background actor was destroyed tried to access
the Background as backgroundActor.background._delegate but when the destroy
signal is emitted, the MetaBackgroundActor was already disposed and
backgroundActor.background NULL.
The rewrite of Mutter's background code (see bug 735637) requires
corresponding changes here - we no longer need to layer multiple
MetaBackgroundActors together.
The general strategy is that a BackgroundSource object is created
per GSettings schema, and keeps either one Background/MetaBackground pair,
or, for animation, a Background/Metabackground pair for each monitor.

Commit 12845f0eef reset translationX to 0 to fix the slide-in
animation of the dash when dragging a search result, but 0 is the
wrong value for the thumbnail slider - the next time it will be
shown, it will just pop up instead of sliding in due to translationX
already being at its target value.
Fix this by making _updateTranslation take the actual visibility into
account and call that to set the correct translation in dragBegin.
Controls are slided in by animating translationX from the actor's
width to 0; however as _updateTranslation() will skip the animation
when the property is already at its target value and 0 happens to be
the initial value of translationX, the initial animation is skipped.
Fix this by initializing translationX to undefined, which will always
differ from a valid target value.
The comment is right, updating the translation should be deferred
to pageEmpty, or else overview controls will just pop up instead
of sliding in. So revert that part of commit 6a7fa52879.

All derived classes are already checking explicitly for action names
(FOO and FOO_BACKWARDS). mutter used to have a META_KEY_BINDING_REVERSES

FOO_BACKWARDS, but this has been removed now, so this special handling
is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=732296
When this flag is set on a MetaKeyBinding, mutter will know that
the keybinding has an associated reverse keybinding triggered with
the shift modifier. However, an undesirable side-effect is that
gnome-control-center keyboard panel does not know that this 'shift'
is reserved for these reverse keybindings and cannot detect
conflicting bindings in this case.
This 'reverse' logic can now be handled at a higher level (in gcc keyboard
panel) so this commit removes it from gnome-shell so that they do not
conflict.

There hasn't been a real need for this but now we are about to add
geolocation settings in control center and it'll be easiser for
control-center to simply toggle a boolean property rather than to have

Later we might also want to add accuracy level settings to privacy panel
so keeping the accuracy level setting around still. However we no longer

The slide of thumbnailWorkspace is shown when entering overview,

ask the width without having created the thumbnails yet, so reporting a
width of 0 and confusing the slide animation.
Currently it works because gjs calls the callbacks following the order
of the clients connecting that signal, and the thumbnailsWorskpace is
connected before the slide ones.
