When closing a workspace due to the last window on that workspace
closing, switch to the overview and show the always empty workspace
rather then just going to the adjacent workspace.

During a drag-and-drop, our pointer grab keeps enter/leave events from
being delivered. That means that after the DND ends, whatever actor is
under the pointer won't have received the enter event it should have,
and any state or hover effect dependent on that won't work right.
By paying attention to the actors we leave and enter we can figure out
what widgets we need to call st_widget_sync_hover() on after the drag.

Showing the right click menu causes errors when ungrabbing focus in this case.
It will soon be impossible to get to the right click menu anyway when a new
notification is showing, because we are never going to show the summary
and the new notification at the same time.
Add Ctrl-Alt-Tab support to ViewTab, and fix the Applications pane to
scroll to track the keyboard focus.
The Windows pane can be switched to, but navigation within the pane is

Fix the "panel" icon to be symbolic. Make the overview parts only show

Unset this._expandedSummaryItem if it is the summary item that is being removed.

PopupMenuManager was pretending that it knew nothing about the menu's
sourceActors, while also trying to handle keynav between them. This
was a big mess, and resulted in bugs in navigation between panel menus
and the Activities button, and it totally gets in the way when trying
to add keynav to the dash (whose menu sources are arranged vertically
rather than horizontally).
Fix this up by moving the panel-specific parts to PanelMenuButton
instead.
https://bugzilla.gnome.org/show_bug.cgi?id=641253
It already doesn't work right, because the PanelMenuButton code
assumes that Left and Right won't be used as part of keynav within a
menu. And the gnome-panel calendar isn't keyboard accessible either,
so this isn't a regression. To be fixed later.

To deal with different CSS in RTL locales, we used to manually add

Currently the icon texture is only updated on style changes when
the icon size is set from CSS and differs from the previously used
icon size.
As the style change may have been triggered by an icon theme change,
textures that are created for themed icons should always be recreated;
given that this is the case for most uses (with the exception of
file thumbnails), recreate the icon texture unconditionally to avoid
complexity.

Commit b1654af406 moved the panel positioning (and thus that of its
corners) before the panel startup animation. As the panel corners now
are mapped while the panel animation is active, the initial style-changed
signal which triggers another repositioning is received after the
initial layout and the corners end up at wrong positions.
To fix, animate the corner positions as well during the startup
animation - if anyone could actually see the animation, the corners
should animate with the panel anyway ...
https://bugzilla.gnome.org/show_bug.cgi?id=643804
Mutter really expects this, as this is how app-specified struts
happen. For instance, if the primary display is beside a taller
screen and is not positioned at the top, then we extend the struts
for the panel with the size of the unused area above the primary
monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642881
Right now we require a strut to be as wide as the full screen to
create a TOP strut. This means that in a multi-monitor scenario (at
least if the primary monitor is leftmost) we will make the panel strut
be Meta.Side.LEFT due to the random side picking for corner objects.
This changes the width/height comparison to the primary monitor rather
than the screen to get this right. Also adds some docs about how
struts work in a multi-monitor situation.
https://bugzilla.gnome.org/show_bug.cgi?id=642881
We need to do the initial relayout before we start up the startup
animation, and the startup animation can't hardcode the position
of the panel to zero.

Increase the icon size of search results for consistency with the
application view. To account for the larger icons, only display
a single row of results per section.
https://bugzilla.gnome.org/show_bug.cgi?id=643632
Search results' meta info currently is expected to have an 'icon'
property holding a Clutter.Texture of a fixed icon size. This
property is used to implement the createIcon() function of BaseIcon,
which is used to actually display the result, ignoring the size
parameter due to the fixed icon size.
Given that all available search providers create this property for
the desired icon size using a function with the same signature, it
appears logical to replace the fixed-sized 'icon' property with
such a function, so that the icon size will be defined by the display
actor rather than the search system.
https://bugzilla.gnome.org/show_bug.cgi?id=643632
Currently section headers in the search view are reactive and run
the corresponding provider's expandSearch() function when clicked,
which should launch an external program displaying all search
results for the section. Unfortunately it is only implemented for
the "Settings" provider, and does not work properly (as it ignores
the search and just launches System Settings).
Also current mockups deemphasize the section header, making the
feature pretty much indiscoverable (except by accident when
interfering with swipe-scrolling).
In conclusion, the feature does not make much sense in its current
form, so remove it.
https://bugzilla.gnome.org/show_bug.cgi?id=643632
Currently the total number of matches for a particular section is
displayed on the left of the section's header. While it made sense
in the old layout where it was close to the section's title, it is
now rather disconnected, and has been removed in current mockups.

Currently we remove a workspace when last window on that workspace closes,
which turned out to be too agressive as some apps open either a splashscreen

_ungrabActor disconnects the event signal handler but does not
check whether it is connected before doing so which can result into
an exception like:
JS ERROR: !!! Exception was: Error: disconnect() takes one arg, the signal handler id

JS ERROR: !!! fileName = 'gjs_throw'
JS ERROR: !!! stack = 'Error("disconnect() takes one arg, the signal handler id")@:0
Unfortunately the evolution-data-server client-side libraries seem to
block the calling thread. This is a major problem as we must never
ever block the main thread (doing so causes animations to flicker
etc.). In the worst case, this problem causes login to hang (without
falling back to fall-back mode) and in the best case it slows down
login until a network connection is acquired.
Additionally, in order to sanely use these evolution-data-server
libraries, GConf has to be involved and GConf is not thread-safe. So
it's not really feasible just moving the code to a separate
thread. Therefore, move all calendar IO out of process and use a
simple (and private) D-Bus interface for the shell to communicate with
the out-of-process helper.
For simplification, remove existing in-process code since internal
interfaces have been slightly revised. This means that the shell is no
longer using any native code for drawing the calendar dropdown.

See commit f2158218bef0c51 in mutter. Basically, we need
to grab org.freedesktop.Notifications before anything else
in the session gets started.
Note: I intentionally removed the Util.killall bits. I believe that
for notification-daemon at least, if we specify
DBUS_NAME_FLAG_REPLACE_EXISTING, we'll take over the name. Not sure
about notify-osd; if that's still a problem, then what we need to do
is add killing (and possibly respawning) of notify-osd to
"gnome-shell --replace", and not have it embedded randomly in a JS file.
https://bugzilla.gnome.org/show_bug.cgi?id=642666
The DBus JS binding will complain if the signature of a method
or of a signal is undefined, so we need to define it even if it
is an empty string, and we need to use the correct property name
for signals.

For applications with no proper desktop file, the window icon is
used as application icon in the tab switcher, but it won't have
the correct icon size. The current approach is to add additional
padding to these icons - the size turns out inconsistent with
other icons, but the icon appears sharp. For the dash it has been
decided that unsharp icons are less evil than differing icon sizes,
so icons are scaled up to the "right" size - for consistency, do the
same in the alt-tab switcher.
https://bugzilla.gnome.org/show_bug.cgi?id=643300
Mainly due to StTextureCache's way of handling fallback icons, an
implementation of BaseIcon.createIcon() may return an icon smaller
than the requested size. Given that BaseIcon is not used for isolated
elements, but rather for groups of related items (App view, Dash,
Search Results, ...), having some elements end up with the wrong
size is more annoying than having some elements end up ugly due to
scaling, so explicitly enforce the requested icon size.

As gnome-shell now switched to use the menu file from gnome-menus,
we no longer have direct control over category names. If such a name

Fix a typo in panel.js, and ensure that all variables used in

Rather than connecting to stage::capture-event and then trying to
guess whether or not a given key-press should be handled by us or not,
handle the end-search-on-Escape case from entry::key-press-event
(since it only makes sense when the entry is focused anyway) and the
start-search-on-printable-key case from stage::key-press-event (which
will only get the events that no other actor wanted for itself).
Similarly, do exit-overview-on-Escape and switch-panes cases from
stage::key-press-event, rather than
viewSelector.actor::key-press-event, so that they will work correctly
even if the keyboard focus is somewhere else. (Also fix a longstanding
bug in the pane-switching code, which was supposed to be disabled when
a search was active, but was checking a non-existent variable.)
https://bugzilla.gnome.org/show_bug.cgi?id=642502
The search entry was taking a sort of grab when it was in the
focused-but-empty state, and would eat up most events for other actors
(except, confusingly, for panel actors). The only bit of "modality" we
really need here is that the entry is supposed to go back to the
unfocused state if you click somewhere outside it when it was in the
focused-but-empty state. So do that.
https://bugzilla.gnome.org/show_bug.cgi?id=642502

When the user cancels the drag while hovering over a window the timeout
handler will throw an exception because the drag actor will be destroyed
at this point.
Fix that by removing the timeout in _onDragEnd.
The xdnd timestamp gets updated on every xdnd-position event,
so while waiting for the window timeout to fire we need to make sure we
update the timestamp when getting on motion to activate the window
with the correct timestamp.

We never get enter events anyway due to the menu code, and if

Currently the menu has a hardcoded width which result into the hover

PopupMenuManager relies on menus being added in the order of the

menu until the status icon menus have been added to make the manager
happy.
This patch modifies MessageTray behaviour so that normal (not urgent)
notifications are not shown when the user is Busy (they're sent
immediately to the Summary area). When status is then changed,
notifications still pending are shown again.
Additionally, when status is modified from Idle to anything other than
Busy, the message tray is forced open for 4 seconds, so that summary
icons are visible.

A PolicyKit Authentication Agent is a construct used to authenticate
one or more identities. See the PolicyKit documentation for more
details on authentication agents and how PolicyKit works:
http://hal.freedesktop.org/docs/polkit/
Since gjs does not support subclassing a GObject class from Javascript
code, we bring in a native class to bridge the VFuncs to GObject
signals. Additionally, this native class also queues up authentication
requests so the user of the native class only has to deal with a
single outstanding request at any one time.
The file js/ui/polkitAuthenticationAgent.js introduces a singleton
that listens for authentication requests via the native class. This
singleton uses the PolkitAgent machinery to do the actual heavy-weight
lifting required for authentication (essentially a PAM conversation).
We currently don't allow the user to pick the identity to be
authenticated.

Complex popup menus require the ability to manager sequences of items

as hide and show.

Current mockups show the panel curving downwards at the edges to
frame the work area and look awesome. Implement those as separate
actors to not affect the struts set by the panel, and synchronize
their state with the corresponding panel buttons so they blend in
with the panel. It might be worth considering whether the corners
should be hidden with maximized windows on the current workspace,
though this might affect the illusion of them being part of the
panel. As the corners don't affect the input region, the small
overlap with windows might not be too bad after all.

We now use a border image on active panel buttons to underline the

the app icon when the button is active.

While related to the status area, the user status button is clearly
not a status icon, and it does not make too much sense in
startStatusArea(), which is about filling the status area with

panel element which is initialized elsewhere. Not a crucial change,

Because the overall parent allocation width immediately when the workspace

Rather than killing the workspace indicator indicator when we remove

When we animating the scale for the thumbnails, the border and

is under the other actors and allocated by our custom logic.

The Overview does not only hold the different elements visible in
the overview, but is also a central point to manage drag signals.
As objects which are constructed in the overview constructor cannot
access Main.overview (as its constructor has not finished yet), we
use misnamed show/hide methods to work around this limitation, which
are called when entering/leaving the overview.
A better way to handle this problem is to remove the limitation
altogether by splitting the overview constructor between internals,
which remain in the constructor, and more complex objects which
need to access Main.overview, and whose initialization is moved
to a public init() function which is called by main.js after the
overview has been constructed.
