NM 0.9.7 is still not released even as a tarball, so fix this to work
with 0.9.6 again for now (although it doesn't do any device name
disambiguation in this case now).

If the setting is enabled, we record the last activated input source
for the currently focused window and switch to it when focusing back
that window. The Overview is considered a window for this purpose.

The current code parses the button-layout setting because MetaButtonLayout

Due to limitations and bugs in SpiderMonkey's GC, wrapper objects
for cairo contexts and similar may not get cleaned up immediately

With panel buttons changing dynamically on session mode changes we can
no longer rely on a corner's respective box style-changed signal to
find the nearest button.
Instead, make the panel take care of telling the corners to look for a
new button when buttons are changed.

Acting on each Show/Hide DBus call immediately may cause a lot of
jittery movement when Alt+Tabbing or even just switching tabs in
e.g. gnome-terminal.
To make the OSK feel sturdier, we wait a bit before actually showing
or hiding it so that we can coalesce tight sequences of Show/Hide
calls. I.e. the last call wins which means that we might end up not
doing anything.
https://bugzilla.gnome.org/show_bug.cgi?id=688646
We can't pushModal() when showing the subkeys popup because that will
cause the application to lose focus and thus we get a Hide() call for
the whole OSK.
Instead, capture events on the main OSK actor while the subkeys popup
is shown so that we can both prevent events from reaching the main
keys but also cancel the subkeys if the user clicks away in the OSK.
https://bugzilla.gnome.org/show_bug.cgi?id=674955
Since we're breaking API already, take this as an occasion to use a
separate interface for all the screenshot-related methods. The interface
name is org.gnome.Shell.Screenshot.
Internally, move all the related code to screenshot.js.
https://bugzilla.gnome.org/show_bug.cgi?id=688004
Since we also support passing a basename now, clients might be
interested in knowing the path used to save the file.
Add an out argument to the interface for that.
https://bugzilla.gnome.org/show_bug.cgi?id=688004
If a non-absolute path is passed to the screenshot methods, treat it as
a basename for the output image, and automatically try to save it in
$XDG_PICTURES_DIR, falling back to $HOME if it doesn't exist.
https://bugzilla.gnome.org/show_bug.cgi?id=688004
The screensaver schema has a key that it is meant for locking down
the ability to switch user when the screen is locked, but support
for it was not implemented in the new screenshield.
Fix that by checking the key before creating the button.
https://bugzilla.gnome.org/show_bug.cgi?id=691042
When you click Suspend from the user menu, the following things happen:
- we lock the screen internally by calling Main.screenShield.lock() and waiting
for lock-screen-shown
- logind emits a Lock signal, which causes us to lock again
- gnome-settings-daemon notices PrepareForSleep, and calls org.gnome.ScreenSaver.Lock,
just in case, so we lock once more
This means that, if you're lucky, you can see the curtain fall down multiple times,
as each .lock() call resets the animation.
https://bugzilla.gnome.org/show_bug.cgi?id=690858
It's common to do actor.grab_key_focus() before the actor is mapped
which means that we can't reliably determine where the actor is at
notify::key-focus time and thus might end up showing the keyboard on
the wrong monitor.
This is happening, in particular, with the run dialog. Delaying until
we hit the main loop allows us to know where the actor finally is
before showing the OSK.
https://bugzilla.gnome.org/show_bug.cgi?id=685856
Rather than add invalid results to the place where you enter JavaScript

org.gnome.desktop.screensaver.lock-delay contains the grace period
of the screensaver: if deactivated within that many seconds from the

This setting correspond to the "Lock screen after" combo in screen

Use the new meta_window_check_alive() to verify if the application is

Calculate an icon based on our current state, not a mess of

Instead of faking it by adding a bunch of main icons and secondary

As we may be flipping the box pointer in response to re-allocation,
like the addition of a new actor to the boxpointer, we can't queue
a re-layout while in a re-layout, so defer.
https://bugzilla.gnome.org/show_bug.cgi?id=690608
Depending on the current state of arrowSide, the box allocation may be
wrong; e.g. if the user requested a TOP, but we flipped to a BOTTOM, the
next request would look to the y2 value of the flipped BOTTOM, which is
wrong.
Instead, use the origin, plus the calculated preferred size of the box.
https://bugzilla.gnome.org/show_bug.cgi?id=690608
Make sure we re-allocate after we flip sides, to ensure that
padding around the child actor is updated correctly. Additionally,
ensure that we flip after we setPosition, as we won't get re-allocated
auotmatically by just changing the position.
https://bugzilla.gnome.org/show_bug.cgi?id=690608
Given that it's modifying state, there's no reason it can't be
using it instead. This makes it easier to use, so we aren't passing

Allow users to smoothly scroll on the volume indicator icon
to adjust the volume. Do this by simply passing the scroll

After the first time the title was placed, we were setting its width,
thus forcing get_preferred_width() to return that as the minimum and
natural width.
To workaround that, explicitly reset the width to -1, -1, causing
StLabel->get_preferred_width() to be called, which would give us a meaningful
value for minimum and natural width.

WindowOverlay was at times seeing bogus values reported as WindowClone

Both WorkspacesDisplay and ThumbnailsBox need to know when windows have been
restacked. Instead of each tracking changes on their own or trying to call
each other, have the overview keep track and do the calculations, emitting
a signal with the result.
https://bugzilla.gnome.org/show_bug.cgi?id=690175
meta_display_add_keybinding() returns a keybinding action ID for
dynamically registered keybindings which can be used to match a

Instead of storing them globally and having an hardcoded list of
engines which are allowed to change their indicator symbol when the
InputMode property changes.

We previously scaled windows to (primary.x, 0), which is wrong if the
primary monitor is not at y == 0. At the same time, change the policy
to pick the hot corner on the monitor the window is on, because that's
closest to where it will appear in the overview.
https://bugzilla.gnome.org/show_bug.cgi?id=690241
This makes the method usable in places where the associated window actor
might not have the right size (such as from window manager animations).
Also, make the method public from LayoutManager.
https://bugzilla.gnome.org/show_bug.cgi?id=690241
If we overwrite a map animation (for example because the actor is now destroyed),
we need to complete it first, otherwise it starts off from a random
middle point. This is the same treatment opacity gets for normal windows.
https://bugzilla.gnome.org/show_bug.cgi?id=690241
The thumbnail controls are not a separate actor in the overview group
yet, so we need to ensure a spacing between them and the workspaces
view.
Instead of exporting the overview spacing, just add a temporary style
class to the workspaces-view actor for it. It will be removed in the
future when we change the layout of overview elements.
https://bugzilla.gnome.org/show_bug.cgi?id=690174
Adjust the layout of the overview and window thumbnails to make them
bigger. Also, make the background shade darker to compensate for the
increased thumbnail density.
https://bugzilla.gnome.org/show_bug.cgi?id=689876
Recreating icons on every style change -- like hover, can have
disasterous effects. Not only is the quick creation/destruction of
the actors bad, but adding/removing actors at runtime queues many
relayouts, which makes the whole system slower as a lot of unnecessary
reallocations are figured out.
While an optimization was here before, it was broken because it
broke high-contrast themes. Connect explicitly to the texture cache
to know when the icon theme has changed, instead of removing a valuable
optimization.
https://bugzilla.gnome.org/show_bug.cgi?id=672941
The message tray actor also includes notifications themselves. We want
our ghost to be sized as the base part of the tray instead.
Just make sure to use the same style class as the base actor then, as

The new privacy panel offers separate settings for the user name
visibility in lock screen and normal mode. The code to support

These are for all search results except apps (and Wanda).
We also simplify a bit the packing of search results, which removes some

Display a '+' icon on the provider icon if there are more results that are

When pressing the overlay key three times, things went like this:
* show(), push a modal
* hide(), will pop a modal after hiding is done
* show(), push a modal
Thus, when the showing is done, and then it activated the hiding,
it popped one modal, but not the other. This patch changes things
to be:
* show(), push a modal
* hide(), will pop a modal after hiding is done
* hide(), no-op
That is, mashing the overlay-key when it's showing will always make
it hide, not mashing an odd number of times.
https://bugzilla.gnome.org/show_bug.cgi?id=688589
BoxPointer's API changed to take a BoxPointer.PopupAnimation
enumeration value, but the code was accidentally replaced with
older code when porting the PopupMenuManager code to GrabHelper.
https://bugzilla.gnome.org/show_bug.cgi?id=689954
"toggle" is used when clicking on the source actor. As we don't
actually have a menu, we don't want to actually take any grabs
through the menu system, so make it a no-op rather than have it
toggle the menu state.
https://bugzilla.gnome.org/show_bug.cgi?id=689954
This is necessary for child popups in menus, e.g. while in a combo box,
clicking outside of the user menu should drop the entire menu, but
clicking on the user menu itself should only drop the combo box.
https://bugzilla.gnome.org/show_bug.cgi?id=689109
I have no idea why we used 'event' rather than 'captured-event' before.
'event' has some really strange quirks that came up when porting PopupMenu

this._gnomecc is currently unused; we actually need a GAppInfo for this
provider if we want to display an icon next to it (see future commits),
so just turn it into one.
We might move this to an external provider altogether in the future.
https://bugzilla.gnome.org/show_bug.cgi?id=689735
This allows us to fix the shortcomings of the original ActivateResult()
method. In particular:
- allow to pass the search terms to the provider
- allow to pass a user interaction timestamp
https://bugzilla.gnome.org/show_bug.cgi?id=689735
The only case when we're interested in using those parameters nowadays
is for DnD, which is handled in a separate method already.
Since we're not going to support DnD for non-app search results anyway,
drop the params from all the activateResults() calls; this will be
useful later since we're going to add another parameter to it.
https://bugzilla.gnome.org/show_bug.cgi?id=689735
We read the implemented version from the search provider's keyfile, and
then create a RemoteSearchProvider object from the right class
accordingly.
Wire ActivateResult() to the new method (without actually passing the
new parameters along) - an actual implementation will be added in a
future commit.

Defining a mode that differs significantly from the default one
can get rather cumbersome. For convenience, allow mode definitions
to inherit from an existing mode.
https://bugzilla.gnome.org/show_bug.cgi?id=689308
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.
https://bugzilla.gnome.org/show_bug.cgi?id=689305
Currently adding a new session mode requires patching the sources.
As defining custom modes can be desirable in some circumstances
(for instance for administrators of kiosk setups), load additional

Now that we use the new 'switch-applications' keybinding for the
application-based alt-tab popup, we can use the 'switch-windows'
keybinding for a more traditional switcher.
Based heavily on the alternate-tab extension from Giovanni Campagna.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
The Shell's alt-tab popup is application-based, so using the
'switch-windows' keybinding for it never really made sense.
Use the newly added 'switch-applications' keybinding instead.
https://bugzilla.gnome.org/show_bug.cgi?id=688913
If the chosen action is not open, the tray should not be closed, to
let the user further interact with it (for example to mute or remove
more sources)
https://bugzilla.gnome.org/show_bug.cgi?id=689296
This is meant to expose the global.session_mode to applications such
as the gnome-tweak-tool, which would need it to differentiate between
the vanilla GNOME Shell mode and the fallback replacement mode.
https://bugzilla.gnome.org/show_bug.cgi?id=689300
Currently we assume that either the initial sessionMode will have
the overview or none of the pushed modes - starting without the
overview and pushing a mode that adds it fails spectacularly.
However this is exactly what we are going to do when loading external
modes asynchronously - we'll initially use the default mode while
the modes are loading, and switch to the mode passed on the command
line when finished. So make sure that the overview UI gets initialized
properly in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=689304
Since commit 0c807bddaf, the run dialog no longer handles Escape
key presses itself but uses the action key mechanism of modal dialogs.
As the latter uses key-release events, our own handling of the Escape
key runs on key-press.
Fix this by bailing out early if anything has pushed a modal in addition
to the overview (like system modals, looking glass, ...).

MessageTray._tween sets the state variable to the in-progress value,

Since the introduction of overlay hover borders, there has a been
a timing disconnection between hiding the border and button, and
this creates noise and reduces the effect of the window+overlay

Solve that by animating the close button too, so that the two actors
are shown and hidden always at the same time.
Also, consolidate the code to make it clear to future authors that
those two items need to stay coordinated.

The panel corners overlap the panel in order to hide the underline
used for active buttons where it is supposed to arc downwards
following the roundness of the corner.
Unfortunately this prevents us from using a transparent panel background,

this limitation by only overlapping the panel if there is a visible
border.

Commit c3cab28 removed bits setting the password char that was used to

Desktop files can specify if the application should only be shown for
specified desktops with OnlyShowIn and NotShowIn directives options.
If a menu category only contained entries for a different desktop, we
were still creating the category.
We now only add a category button if there is at least one application
to be displayed in this category.
https://bugzilla.gnome.org/show_bug.cgi?id=687970
We need to do a better job of indicating login process. This can
sometimes take a few seconds (particularly if you get your password
wrong): we need to give better feedback of what's going on.
This adds a spinner next to the login button if the authorization takes
some time.
https://bugzilla.gnome.org/show_bug.cgi?id=687113
The login dialog had these issues:
- the entry was not really disabled, you could still edit text
- the sensitivity state was not reset on verification failure
- the session list was not disabled
The unlock dialog had these issues:
- "Login as another user..." was not insensitive
- redundant password char setting, overwriting the one given by the
question
The entry insensitive style was also wrong.
https://bugzilla.gnome.org/show_bug.cgi?id=687113
The "Sign In" button of the login dialog has its look disabled when the
entry is empty, but it can still be triggered by the Enter key.
This fixes the modal dialog so it does not trigger the action of an
insensitive button, and also means we do not need to connect to the
"activate" signal of the entry anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=687113
Make the button layout public for callers to be able to have more

Open a modal dialog, try to open the message tray -> no effect, the message

The top panel and message tray icons were by default a gnome foot and

MessageTray tweens both opacity and y to hide or show _notificationWidget,
but only y when expanding it. This means that an existing tween to hide
the notification will continue running, clearing the notification state.
If the hiding one completes before the showing one, the onComplete handler
will throw an exception (because the notification was nullified) and
therefore break the state tracking.
https://bugzilla.gnome.org/show_bug.cgi?id=683986
Instead of adding search providers to the system as we find them, wait
until we loaded information from all the directories, and then add all

This will be useful when we will sort the providers information
according to the sort order saved in GSettings.
https://bugzilla.gnome.org/show_bug.cgi?id=687491
The AnimatedIcon does not have an API for controlling the animation but
relies on the :visible property changes to start and stop a timeout used
to update the frame.
This has the inconvenient of having a side effect when visible is set to
true multiple times, and is not really the API expected from such
component. Also, there is a race if it is displayed before the images
are loaded: there is no child yet and thus we get this._frame = NaN
which leads to a crash.
Switch to a play/stop API instead, and add a load event callback to the
TextureCache.load_slice_image to exactly know when we can start using
the images.
https://bugzilla.gnome.org/show_bug.cgi?id=687583
As we now allow the ctrl-alt-tab popup on the lock screen, it should
be possible to navigate back from the top bar, so add the corresponding

https://bugzilla.gnome.org/show_bug.cgi?id=688202
The original condition the property was based on was added to make
the a11y switcher available in the login screen, though it did never
work properly - after popping up the switcher, additional tab key
presses were ignored. As we are now able to filter bindings much more
selectively, we can simplify the check and drop the sessionMode property.

With the new flexible system in place, there's no point explicitly
hardcoding some built-in keybindings; just use the generic mechanism

For now we just use it to assign an identifier to modal modes in

When updating the dash, we already avoid all animations while the
overview is hidden. However, as we are using Main.queueDeferredWork(),
updates may be deferred up to ~20 seconds while the overview is hidden.
If the overview is entered before a queued update has taken place, it
will be run immediately on map - as the overview is visible by then,
this means animating any outstanding changes.
Work around this by skipping animations during overview transitions as
well.

If the session mode has no locking support, screenshield had code to

When in the overview, if you move the mouse cursor over one of the
application launchers in the dash, all the unrelated windows are dimmed
both both in the window view and in the workspace view.
It helps to easily understand whether or not there are already opened
windows for this application, and where they are. It can also help in
differentiating the windows in the overview (sometimes the thumbnails
aren't precise enough to easily know which thumbnail belongs to which
application).

We simply hide the label when the popup is opened instead of relying
on the popup state when the hover state change.
To do this we replace the flag isMenuUp by a 'menu-state-changed' signal

code that need additional changes for the bug.

Initializing this synchronously means that we will possibly wait for the
process to be auto-activated and answering to our call.
If the process is already running it also might not answer immediately
our request, as it might be doing sync I/O.
The right thing to do is to initialize the proxy asynchronously; there
