LoginDialog has a private _user, but UserListItem has a public user.
Easy to get wrong since _user would be the right thing to type in 90% of
this file.
Any time estimates we can come up with are notoriously unreliable;
even on devices that report correct (dis)charging rates, any change
in workload, screen brightness etc. can throw our estimate off by
a huge amount. This is further compounded by bad firmware and battery
firmware which reports inaccurate data as neither Windows nor Android do
not use that data.
So instead, limit ourselves to only showing the current percentage
and leave its interpretation to the user.
As an added bonus, we end up with shorter strings that are less likely
to cause problems with ellipsization when translated.

Builtin chat and network notifications already follow the notification
policy of appropriate applications, it makes sense to do the same for
autorun notifications to give users control over hotplug notifications
in Settings.
If we detected that Bluetooth devices were setup, show the Bluetooth
menu so that users can easily turn Bluetooth back on.
This is a bit of a hack, as we cannot detect whether there is a
Bluetooth adapter at all when it's disabled, so we cannot tell whether
there were any Bluetooth devices setup, at some point. This state is
saved in the gnome-shell GSettings in the had-bluetooth-devices-setup
key.
Checking whether we saw Bluetooth devices at one point is a good
enough guess of whether there will be some in the future.

It's very unexpected that a spinner animation would
preempt idles from running.
This commit runs the spinner animation with a low
priority to ensure it doesn't take over the main
loop.
https://bugzilla.gnome.org/show_bug.cgi?id=754814
Right now the spinner animation updates every 14ms.
60 frames per second would be one frame per 16.667ms,
so we're waking up more frequently than we need to.
This commit changes the wakeup to happen after 16ms.
https://bugzilla.gnome.org/show_bug.cgi?id=754814
If the source actor is sized 0x0, the grabHelper will close the menu
on button release if the menu ends up flipped because in that case the
release event happens when the pointer is neither over the source
actor (since it's 0x0) or over the menu actor. A zero sized source
actor works for the non-flipped menu case because the menu's actor
itself ends up underneath the pointer.
https://bugzilla.gnome.org/show_bug.cgi?id=756605
If we get another effect on the same actor, we should make sure to
remove the clone through the "overwrite" methods provided by Tweener, or
there will be a race that might end up with a stray clone being left
around.
https://bugzilla.gnome.org/show_bug.cgi?id=756714
The translation should describe the difference between the fullscreened
and unfullscreened position of the window - however we are currently
assuming a fullscreen position of (0, 0) instead of the monitor's origin,
which causes glitches on dualscreen setups.
https://bugzilla.gnome.org/show_bug.cgi?id=756697
Some labels in the system status menu - namely network names - are out
of our control, and may thus grow the width "infinitively" unless we
restrict the menu width. So far we have been doing this by setting a
fixed width or max-width, but any value we put there might end up
being too restrictive in some locales. Instead, request a width that
fits all the labels we want to show unellipsized and use that instead
of an arbitrary limit.
https://bugzilla.gnome.org/show_bug.cgi?id=708472
We use the newly introduced feature from Mutter to hook up our own
fullscreen and unfullscreen animations.
To give the illusion of a transition as smooth as possible, we create a
snapshot of the current contents of the actor before its state is
changed, and crossfade between the two states while the size changes.
https://bugzilla.gnome.org/show_bug.cgi?id=707248
StIcon will skip loading the texture when its theme node is unset (which
may happen on style changes while the widget is hidden). While our size
request to compute the dash icon size will create the icon's theme node
if necessary (and of all its parents), a missing texture can still throw
off our computation.
Make sure this doesn't happen by ensuring the icon's style first, so the
texture is updated in response to StWidget::style-changed if necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=745649
When adjusting dash icon sizes, we compute the icon padding by subtracting
the configured icon size from the first icon actor's preferred size. To
make sure that the preferred size correctly corresponds to the current
dash icon size even while the icon is animating, we enforce the size
before the size request. For that we used to temporarily manipulate
the icon texture size directly, but commit e92d204d42 cleaned this
up to use the setIconSize() method instead.
This does not work however, as the icon actor's iconSize property will
always match the dash iconSize property, making the method a noop. So
go back to the original approach of enforcing the texture size to make
sure we always base our computations on correct values.
https://bugzilla.gnome.org/show_bug.cgi?id=745649
There is nothing particularly critical about this notification, it
was only marked as such to get certain behavior like auto-expanding
and sticking-around to be acknowledged by the user (as it offers
more actions than the summary notification, so it is frustrating
when it goes away because it was missed).
As all notifications will now stay visible until we are sure the
users has seen them, the latter reasoning no longer applies.
Auto-expansion doesn't appear too important and may even be considered
annoying by users, so remove the CRITICAL hint now.
https://bugzilla.gnome.org/show_bug.cgi?id=657923
We are currently erroring out when the tab chain doesn't contain at
least one window for an app which might happen for windows that don't
take focus like xeyes. This leaves us in a state where we can't show
the switcher at all. Let's just ignore these apps instead of looking
broken.
While the GtkSettings::gtk-shell-shows-app-menu property is meant to
reflect a desktop capability (i.e. in the GNOME case: the app menu is
shown in the top bar), it is possible for users to overwrite it.
Respect the setting and actually hide the menu in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=745919
Refer to the system menu in the top bar as "System" rather than "Settings" as
it contains more than just settings and "Settings" is already used for the
settings panel. "System" is also used elsewhere, so include context for
translators.
The destroy signal handler is kept connected despite the NotificationMessage
being destroyed, which leaves dangling NotificationMessage objects that will
be mass destroyed when the Notification object these depend upon is finally

to temporary freezes or other more funky issues when recursion limits are
hit.

When the user successfully types their password, we should hide
the spinner from the button well right away, so it doesn't

The code previously tried to stop spinner after it was hidden, but
due to an incorrect check was only stoppig it after it was shown.
Also, it was only stopping after hiding due to an animation, and

We only need the user verifier for the purpose of user verification.
Once it's complete we should clear it so it doesn't get in the way
later.
This fixes a bug introduced in commit 3c8c5a5570 that leads to the
user session crashing when the login screen is reactivated.
https://bugzilla.gnome.org/show_bug.cgi?id=753181
We fade out the authentication prompt when a user successfully
logs into a user session. We reset it and fade it back in when
the user switches back to the login screen VT.
The problem is, we only fade it back in if the auth prompt status is
VERIFICATION_SUCCEEDED. It's possible for it to be NOT_VERIFYING
if the authprompt gets reset for some other reason in the interim.
This commit changes the check to be more precise. We now only skip
the fade-in, if we're already faded in, and we only skip the reset if
we're already reset.

Follow the design we have in gtk+ for buttons dialogs,
which are at the bottom and they expand full width, having

The user should be allowed to cancel if verification hasn't

commit changes the authPrompt cancel function to not

https://bugzilla.gnome.org/show_bug.cgi?id=752739
Normally the user isn't allowed to proceed passed
the username question until they've filled it in.
To ensure this, the authprompt code desensitizes
the next button when the number of characters change to
zero.
Unfortunately it fails to desensitize the next button
up front when the entry starts out empty.
This commit addresses that bug.

When chrome is added with the trackFullscreen parameter, the actor's

Since the introduction of per-source notification policy in commit

If we aren't the active session clutter can't animate and thus we
can't expect the shield to be shown before releasing the suspend
inhibitor so we should release it immediately when becoming inactive.
https://bugzilla.gnome.org/show_bug.cgi?id=749228
The whole point of holding a suspend inhibitor is to be able to lock
before suspending.
Currently, when resuming we immediately take the inhibitor without
checking that we're locked which means that we won't be able to
release this inhibitor if we don't unlock at least once.
To prevent that and to better match the inhibitor's intention in the
first place, we can tie the inhibitor with not being locked. In
practice, we also want to let the locking animation finish before
suspending, so we'll tie the inhibitor with not being active
instead.
https://bugzilla.gnome.org/show_bug.cgi?id=749228
This could happen if we are VT switched away and an animated
activation is requested because we're preparing to enter sleep. Since
we don't animate in this case we'd never reach
_completeLockScreenShown() before coming out of sleep, at which point
we _inhibitSuspend() again and would leak the previous inhibitor.

Commit 08690d658f generalized the banner-blocking behavior of the
dateMenu to all menus that would obscure the banner. However setting
up the 'open-state-changed' handler only when an indicator is added
does not work for indicators that change their entire menu (like the
app menu) - we currently end up with menus with no connected signal
handler, and throw an error when trying to disconnect an invalid
signal ID.
To address this, add a new PanelButton::menu-set signal and use that
to set up the 'open-state-changed' handler.

For barriers like the hot corner which are made up of multiple axis
barriers, make sure that all the barriers have been left before
resetting the barrier.
We currently block banners while the time+date menu is open, as it
would obscure the notification. However it is not necessarily the
only menu for which this is the case, so generalize the behavior
to all menus that would overlap banners when open.
https://bugzilla.gnome.org/show_bug.cgi?id=745910
As notifications appear in the time+date dropdown's message list, there's
a strong relationship between notification banners and the menu. However
while the time+date menu is centered by default, which matches the banner
position, its actual position depends on the session mode - in particular
it is moved to the right in classic mode.
Reinforce the relationship in these cases by moving notification banners
underneath the time+date menu.

According to systemd logind's documentation, the CanSuspend() method
"returns 'na' in case "the operation is not available because hardware,
kernel or drivers do not support it", while "'no' is returned if the
operation is available but the user is not allowed to execute it".
See http://www.freedesktop.org/wiki/Software/systemd/logind
Thus, we need to return true here when the reply for the CanSuspend
method is neither 'no' nor 'na', or we would providing false positives
in cases where suspension is simply unsupported.

libcaribou was designed to generate X events which works under wayland

and for shell chrome.
This patch adds a simple caribou display adapter which inherits from
its X display adapter and allows us to continue to work for X clients
and at the same time makes the OSK work on shell text entries by
sending key events directly to the focused text actor.
Making the OSK work for wayland clients requires much bigger changes
at various levels in the stack and either not using libcaribou or
re-working it substantially so that's left for future work.

Sources are destroyed with their last notification. This is usually the
correct behavior, however in case of chat sources, the corresponding
telepathy channel might still be open, and any further messages that
should trigger a notification are lost because chat sources are only
created when telepathy's channel dispatcher notifies us about a channel
(via ObserveChannels).
Loosing messages like this is unexpected, so keep chat sources around
even without notifications while the channel is open.
https://bugzilla.gnome.org/show_bug.cgi?id=747636
Currently the lifetime of a chat source and its single notification
are tied together. While this apparently makes sense, it means we
will lose all follow-up notifications when a source is destroyed
with the corresponding telepathy channel left open. We will fix this
soon by tying the source to the channel's lifetime rather than the
notification, prepare for this by recreating the notification if
necessary.

It's possible for a user to type their password so quickly
that GDM hasn't even had time to ask for the password yet,
much less have time to process the answer.
In that situation, we tuck the user response away as

ready for it.
The problem is, there's a bug in the code, where we send
null for the service name in the answer, instead of the right
service name (say "gdm-password").
This commit addresses the bug by making sure we don't pass the
answer along, until the service name is properly set in

In recent glib, change notifications don't actually happen unless all

Since commit 75745fc23f, the bodyStack itself is no longer start-aligned
to not break custom body actors like chat notifications. However we still

Special-casing banners of resident notifications was really a
thinly veiled special case for chat notifications, as those were

We currently use the setActiveSession method to both mark a menu item as

Since gdm is ultimately in charge of the state, we should decouple this

what gdm thinks is the current session.
This prevents state getting mismatched and oscillations from happening,
where we get in a loop of constantly telling gdm what the session is.
