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
modes from JSON files.
https://bugzilla.gnome.org/show_bug.cgi?id=689304
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, ...).
https://bugzilla.gnome.org/show_bug.cgi?id=688196
Invalid ID errors from that function are normal, because the set

MessageTray._tween sets the state variable to the in-progress value,
so it must be sure that at the end of the animation the value will
be the corresponding final and nothing else will happen in between.
https://bugzilla.gnome.org/show_bug.cgi?id=683986
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
as a single unit.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=688966
Turns out that tweener has a very complex logic to decide when a new

On additional monitors the workspacesView takes up the entire monitor

The panel should change appearance according to the sessionMode,
so add a new panelStyle sessionMode property which allows to

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,
as the overlapped area ends up with the wrong transparency. Work around
this limitation by only overlapping the panel if there is a visible
border.
https://bugzilla.gnome.org/show_bug.cgi?id=684573
Commit c3cab28 removed bits setting the password char that was used to

Without that code, in complex PAM setups you can end up with a visible

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
tray is blocked by the dialog.
Close the dialog, try to open the message tray by pointer -> still

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

symbolic apps icon of the dash, and the windows icon is also improved.
https://bugzilla.gnome.org/show_bug.cgi?id=641303
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
providers at once.
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
elements to the switcher.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
With the new flexible system in place, there's no point explicitly
hardcoding some built-in keybindings; just use the generic mechanism
for everything.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
Currently we hardcode the set of keybindings that are available in the
overview; add a generic mechanism to specify in which KeybindingModes
a keybinding should be available.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
For now we just use it to assign an identifier to modal modes in
which we want to allow some keybindings, but we don't use it for
any actual filtering; we'll start doing this shortly.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
We are currently using a hack to allow a select set of keybindings
in the overview. Implement the new MetaPlugin keybinding_filter

Due to an oversight, the width of the password entry is currently

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
unlock automatically, but it did so by checking the return value of

At the moment, only the mouse can be used to focus and answer a chat

If I click on "Not listed?" in the login screen, I come to a username
field with two buttons: "Cancel" and "Sign In".
Clicking on "Sign In" doesn't actually sign me in though - it takes me
to the login entry. It would be better to rename "Sign In" to "Next" for
the username stage, therefore.
Gdm emit a signal to ask a question or a secret, but we can not know if
this is the last authentication question, hence we only use "Sign In"
for secret questions which improve the situation a lot.
https://bugzilla.gnome.org/show_bug.cgi?id=687656
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).
https://bugzilla.gnome.org/show_bug.cgi?id=657315
This has also the benefit of getting the application even if it can not
be retrieved through AppSystem, which can happen if the runtime WMClass
does not match the one of the desktop file.
This especially looked wrong with the following commits related to the
bug.
https://bugzilla.gnome.org/show_bug.cgi?id=657315
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
on the AppWellIcon. This simplifies the dash label visibility handling
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
are try/catch blocks in place for when the object is not available, or
not properly initialized.
https://bugzilla.gnome.org/show_bug.cgi?id=687491
This is called in the main thread, which we should never block for
synchronous I/O.
Since the operation we're wrapping is async already, just use
g_file_query_info_async() instead.
https://bugzilla.gnome.org/show_bug.cgi?id=687491
Remote search providers install an auxiliary keyfile to specify
static information, such as the object path/bus name needed to activate
the binary. Such keyfiles also specify the application the providers
pushes results for; currently, we support two formats for application
information
- two fields, "Title" and "Icon" that specify a (translatable) title and
an icon name for display
- one field "DesktopId" that specifies the desktop file name of the
application backing the provider, which obsoletes the previous
Title/Icon syntax
Since all providers in GNOME use DesktopId now, and we need to ensure a
remote search providers is always backed by an application for future
development, this commit drops the support for the older syntax.
https://bugzilla.gnome.org/show_bug.cgi?id=687491
Switch from a ClutterDragAction to a ClutterGestureAction, that gives
us the velocity of mouse motion at each step, and use it to compute the

The background is the same as the normal desktop, so we blur and
desaturate it to clearly show that it's not the normal system state.
To do so, we don't use standard ClutterEffects, to avoid the FBO
indirection. Instead, we take advantage of MetaBackgroundActor support
for GLSL code and paint the shaded background texture directly.

In some deployments showing a user list at the login
screen is undesirable.
GDM's fallback login screen has a configuration key:
org.gnome.login-screen disable-user-list false
that causes the user-list to get hidden.
This commit adds similar functionality to the normal,
shell-based login screen.
Based on a series of patches by Marius Rieder.

Right now when a user clicks "Not Listed?" they end up
seeing a session list that gets reset after they enter their
username.
This commit hides the session list until the username has
been entered.
https://bugzilla.gnome.org/show_bug.cgi?id=660660
For the "Not Listed?" case we will need to be able
to identify when the user has entered their username.
Once we have a way of tracking when the username is
entered, we can then defer showing the session list
too early, before the user can reliably pick a
session.
This username tracking will also be important for
implementing a disable-user-list configuration key.
If the config key gets toggled off at runtime, we'll
need to know if we're at a disruptive part of
the authentication process or not, so we know whether
we can can expose the user list right away, or wait
until the authentication conversation finishes.
Right now, we pass null in for an initial username,
and let the PAM machinery ask the user, which means we
have no good way of knowing when the username is entered.
This commit changes the "Not Listed?" code to ask the
user their username up front, before starting the PAM
conversation in much the same way we do if the user
picks a user from the user list.

After some changes, the tooltip label at the dash is not available

shell_mobile_providers_parse() was returning the country information split
into a hash table with providers and a hash table with country names. This
patch merges both outputs into a single per-country object, so the parse()
method now returns a GHashTable with the following element-type:
(element-type utf8 ShellCountryMobileProvider>)
This also avoids more complex setups like returning lists inside of hash tables,
which was actually breaking either g-i or gtk-doc.
shell_mobile_providers_parse() was also modified to allow inputting the paths
of the country codes and provider list files to use. If paths are not given, the
default ones will be used. This helps us to provide test files during unit
tests.
Both the findProviderForMCCMNC() and findProviderForSid() methods are exported
out of the GSM and CDMA specific classes, and new unit tests for them are
implemented. Tests can be run manually with:
$> ./tests/run-test.sh tests/unit/mobileProviders.js

The AnimatedIcon does not have an API for controlling the animation but

While looking at how the plymouth implementation was built, I was so
short-sighted and focused on the string "_XROOTPMAP_ID" that I didn't
realize it was the name of the standard background on the root window.
Remove our own implementation, and switch to using a standard mutter
MetaBackgroundActor.
https://bugzilla.gnome.org/show_bug.cgi?id=682428
Rationale:
- Getting something out of the way should be quick;
- Very few things in the real world move linearly so, linear
animations, especially for something as big and visible as this,
felt too artificial;
- Moving the curtain out should start slower to make it feel like
having weight (it fills the whole screen after all) but quickly
accelerate towards the end to make it snappy too.
https://bugzilla.gnome.org/show_bug.cgi?id=686745
When the summary notification is open when the tray is closed, we end
up with two concurrent animations: the notification fading out, and the
tray moving away from underneath it. Sliding out the tray should be the
primary transition here, so hide the notification immediately to not
draw the user's attention away from it.
https://bugzilla.gnome.org/show_bug.cgi?id=686888
Having the close button move away from under the pointer after
clicking it is confusing and distracts from the main transition,
which is hiding the notification. Just hide it immediately.
https://bugzilla.gnome.org/show_bug.cgi?id=682237
Rather than destroying the entire source, which is unintuitive, simply
close the notification. Removing the entire source is still possible
by right-clicking on the summary item and choosing "Remove".

GDM has a 'logo' key in its schema to allow distributors to add
some branding. It is currently placed above the user list, which

Activities button instead.
https://bugzilla.gnome.org/show_bug.cgi?id=685852
Currently close() is a no-op when the menu has already been closed.
However, repeated calls could pass different animation parameters.
For instance in the user menu, we try to hide the menu immediately
before locking the screen, to avoid the popup jumping across the
screen while fading out - as we do this from the corresponding
item's activate handler, the closing is still animated if the menu's
own handler (which requests a full animation) is run first.
Fix this by changing close() to overwrite ongoing animations before
bailing out early.
