It has been deprecated for a while in favor of GdkRgba, though in our
case translating ClutterColors to an intermediate color type before
setting _NET_SYSTEM_TRAY_COLORS is a bit silly, so just move to
ClutterColor as the rest of the code base.
Cut down on boilerplate by using the (no longer that) new helper
macros. We don't care about breaking ABI in private libraries, so
use G_DECLARE_FINAL_TYPE even where the class struct used to be
exposed in the header, except for types we inherit from ourselves
(obviously) or where the class exposes any vfuncs (where changes
could affect inheritance in extensions).
Both ShellAppSystem and ShellTrayManager are used as singletons, which
significantly reduces the usefulness of inheritance - it's unlikely for
extensions to inherit from them anyway (AND use any of the vfuncs), so
drop them to allow defining the types as final in an upcoming commit.

There is nothing preventing callers from replacing the internal
layout manager, and as long as the replacement is a (or derives

losing a bit of automatic property mapping - and the latter is
easily fixable by moving the setup out of the constructor.

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.

The JS code could still be holding on to a reference to a window-backed app
after all windows have vanished. (For example, the dash queues an idle to
refetch apps and display them.) Avoid dying with an error message if we
attempt to activate or otherwise manipulate such a window.

The default pipeline color is opaque white and blending is turned
off. If we only draw with that color (e.g. because animations are
disabled and we're always drawn with opacity == 255), blending is kept
disabled since cogl_pipeline_set_color() returns early if the color
doesn't change from what was there before.
In our case we always want blending to be enabled which we can achieve
by setting the blending string ourselves.

Since commit 4f1f226828 we only consider buttons clicked when the
release event had a corresponding press event. However as we use
the hover state to check whether a release event actually occurred
on the button, we dismiss any clicks in cases where we missed the
enter event - most likely due to some other actor holding a grab.
Instead, check whether the button contains the event's source, which
should be less error-prone.

GObject-Introspection started warning for wrong annotations, and
StGenericAccessible::set-current-value has a return value annotation

Which, coupled with fatal warnings, breaks the Shell build.
It may be 2015, but users still stumble upon the occasional .desktop

offending apps.

When the last interesting window of an app-backed window is removed,
we'll transition it back to STOPPED, but we transition the state and
send out the signal before we clear the running state.
This means that any listeners to the state-changed signal might
encounter a window-backed app that has a running state, but no
windows. If they call, e.g. shell_app_get_name, while in this state,
they'll encounter an assertion fail.
Apps that are starting might have uninteresting windows like splash
screens pop up and then go away (like LibreOffice), even when
startup-notification hasn't completed yet. In those cases, we don't
want to transition the app back to stopped -- it should remain in
the running state.
Our StartUpWMClass heuristics use a StartupWMClass -> .desktop ID
mapping built from the list of all installed applications. In case
of multiple .desktop files setting the same StartupWMClass, we
currently simply pick the last one returned by g_app_info_get_all (),
which can be a bit surprising:
A window with WM_CLASS 'emacs', launched through a .desktop file
named 'emacs.desktop' with a StartupWMClass of 'emacs' maps to ...
'emacsclient.desktop'!
Make this case a bit less random by preferring the app info whose
ID matches the StartupWMClass.

libcaribou was designed to generate X events which works under wayland
sessions for X clients but obviously doesn't work for wayland clients
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.

We currently don't have any code either in gnome-shell or

The current code assumes that an embedded window will correspond to
a single MetaWindow over the entire lifetime of the icon, which is
incorrect - the embedded window is unmanaged on Unmap and a new
MetaWindow will be created the next time the embedded window is
mapped. As we currently ignore the new MetaWindow completely, it
will be shown normally in the scene instead of the embedded clone
as intended.
Fix this by setting up clone and window actor each time the embedded
window is mapped rather than once in shell_gtk_embed_set_window().

If users click outside the search entry while it's empty we reset and
thus give up key focus. This means that when using an input method

The lookup table used by get_app_from_window_pid contained only pids of
apps launched by gnome-shell itself, but not pids of apps running before
gnome-shell was (re-)started. Also the pids in that table might not even
be the pid of the process that is actually showing the window if wrapper
scripts are used.
Instead use shell_window_tracker_get_app_from_pid which uses the pids
from the windows themselves.

Themes - namely the HighContrast one - may now request symbolic
icons rather than fullcolor ones. In order to have recoloring
work as expected in that case, we will need a theme node to pick

GTK+ added support for a -gtk-icon-style property in themes to
enforce a particular icon style. Do the same for shell themes

'regular' - enforce fullcolor icons
'symbolic' - enforce symbolic icons

The window actor shouldn't have been picked since it has an empty
input shape, but bugs in mutter weren't properly interpreting that.
Since the Wayland restructure, the MetaWindowActor isn't actually
reactive anymore, it's the MetaSurfaceActorX11, so this code isn't
doing anything.
It's implemented similar to the padding property, but instead of taking
into account the margin values at drawing time in node-drawing, we set
the clutter actor margins in StWidget when the style is computed.
In the case that a CSS margin is not specified, we don't to set a value
of 0 to the clutter actor margin. In this manner it allows to use
Clutter margin values set in the code. However, the margins that are set
both in the code and in the CSS on the same side, the result is
unpredictable.
We avoid to set the clutter actor margin values to 0 if there's no CSS
margin values defined, so we still allow clutter actors to use margin
set in the code.

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.

Wayland applications don't tend to have very useful WM Class properties,
as GTK+ isn't very good at picking an appropriate application ID. While
we should likely fix GTK+ to pick a better app ID, we do have the
existing gtk_shell for more accurate information. The only problem is
that the gtk_surface is set after the MetaWindow is constructed, and
we're not listening for changes on the GTK+ application ID.
Listen to changes on the GTK+ application ID to fix app tracking for

Commit 6c2f3d1d17 moved pref overrides into JS to implement
session mode specific overrides in a clean and generic way.
However that approach comes with a cost - doing the overrides only
after having handled over control to JS means that the core will
be initialized with the non-overridden settings before changing
to the correct values. In the best case this is unnecessary work,
but it can in fact have a worse effect: when initializing workspaces,
we will restore the previous number of workspaces when using
dynamic-workspaces and reset to the configured number otherwise.
As the non-overridden default for dynamic-workspaces is FALSE, we
can easily end up moving the user's windows to the "wrong" workspace.
Now GSettings is expected to grow support for session specific defaults,
which will render our entire override system obsolete (yay!). Given
that, it seems acceptable to use a less generic (and uglier) approach
in the meanwhile, in order to fix aforementioned problems. So move
overrides back before core initialization and just hardcode the
session-mode => override-schema relation.

clutter_device_manager_get_core_device calls XIGetClientPointer, which

So far we have assumed that whether or not a window is interesting
is static. In general this is the case, but as it is legal for the
underlying properties to change at any time, there are of course
offenders that actually do this (flash I'm looking at ya).
While we used the property to determine whether a window should be
tracked or not, the worst case was showing windows that should be
hidden or missing windows that should be shown.
However as we nowadays base an app's running state on the number of
interesting windows, we need to be more careful in order to avoid
ending up with running apps with no windows.

With the lastest ShellApp changes, an app is considered stopped
when the last "interesting" window is closed. However the app
may still track non-interesting windows, so if we unref the
running state on the state transition, we hit an assertion later-on
when trying to remove the non-interesting window.
Fix this by keeping the running state around until the last window
is closed.
https://bugzilla.gnome.org/show_bug.cgi?id=722840
An app should be considered running if it has at least one "interesting"
window, however the code considers an app running if it has at least
one tracked window. This was fine while we were only tracking interesting
windows, but since commit d21aa0d85f this is no longer the case.
So keep track of the number of interesting windows as well and use that
to determine the running state.

It is possible to associate an application's window with a different
application using the transient_for hint. However we currently only

for instance, get_window_app() will not necessarily return the same
value for all windows retrieved via shell_app_get_windows().
Fix this by looking at the transient_for hint when making the original

StWidget::popup-menu is emitted when Menu/<Shift>F10 is pressed,

from X when the key is physicall released.

Since commit 1ebb162a00 moved JS sources into resources,
the extension-prefs tool was broken. To fix it, we would either
need to generate an external GResource in addition to the generated

the script, or turn gnome-shell-extension-prefs into a binary with
the JS resources compiled in.

Specifying the session mode on the command-line doesn't play
well with session management (since the saved session desktop
file well either drop the specified session mode, or force it
always, even if the user picked a different mode at the login

This commit adds support for specifying the session mode via an
enviroment variable. For now, keep the old command line interface

The hash table must keep a copy of the IDs, because the GAppInfos

This was possibly not a problem if the GAppInfos were referencing

get_secrets_keyring_cb() contained an optimization (copied over from
nm-applet) that avoided a D-Bus round-trip when NetworkManager sent
secrets hints that were not satisified by the user. This code did
not properly handle empty hints though, and proceeded to always
request new secrets whenever empty hints were sent. Remove this
code entirely since the complexity is not worth it (per Jasper).
Second, get_secrets_keyring_cb() was mishandling VPN secrets which
were marked as "always ask". Because the VPN secrets are not GObject
properties because they cannot be pre-defined, they are passed in
a hash table that is a GObject property marked 'secret'. Unfortunately,
that means that the shell agent cannot determine their secret flags.
But since the VPN plugin auth dialogs have much better information
about what's required than the shell agent does, always ask the VPN
auth dialogs to handle the secrets requests after grabbing any that
already exist from the keyring. This is also what nm-applet does.

Filtering out "non-interesting" windows beforehand as we currently do
means that we may get properties that should be based on all windows,

Sorting actors by the distance in the axis of movement first and against
the axis otherwise means that if we have a situation like:
A F
B
where "F" is the focused actor, and it slightly overlaps with B vertically,
then we'll choose "B" to go left, rather than "A", which is most likely
what the user intended.
This is especially apparent in the overview where slight window size
differences mean we might not get an exact grid shape.

Rather than scanning all apps for searching, use Ryan's new desktop
file index and the glib support APIs for app searching instead of our
own system.
https://bugzilla.gnome.org/show_bug.cgi?id=711631
While unfortunate that we still have to scan all apps with get_all(),
support for this feature will be short-lived, so hopefully we can drop
it in the future as new apps adapt to the desktop file / app ID
recommendations.
For now, simply scan all desktop IDs.
https://bugzilla.gnome.org/show_bug.cgi?id=711631
Systemd-for-the-user-session would also do this, but that's a deeply
invasive change that I may not actually get to this cycle. This
change is tiny and non-invasive, but provides an important benefit:
You can actually reliably tell *which* applications are logging which
messages (assuming they're launched by the shell).
This actually complements a recent change in DBus:
See https://bugs.freedesktop.org/show_bug.cgi?id=68559
which does a similar thing for bus activated apps.
https://bugzilla.gnome.org/show_bug.cgi?id=711626
Rather than create all ShellApps up-front, create them lazily. We really
had no reason to do this before as we were scanning GMenu to get all the
apps, but doing this can remove a need for get_all, which is slow and
memory-hungry.
We want to transition to a system in the future where we have a desktop
file cache. As we no longer differentiate categories or similar, it no
longer makes sense to have app visibility based on categories. Thus,
we no longer need to use gnome-menus to list all apps. The potential
issue here is reloading all desktop files when new files are created,
but this can be dealt with individually.
The "All Applications" view still uses gnome-menus.
https://bugzilla.gnome.org/show_bug.cgi?id=698486
Since appDisplay.js makes its own GMenu tree, it's not necessary
anymore. This does mean that searches will show apps in NoDisplay
categories, but that's an obscure enough edge case not to matter.

This does remove support for legacy prefixed app infos with

It's a broken method when it comes to giving us a useful GDesktopAppInfo,
and it's hard to fix libgmenu properly, so simply recreate the app info

We want to move away from gnome-menus eventually, so the simple
utility method isn't really worth keeping around. Reimplement it
in the one place that uses it.

gcr/gnome-keyring don't handle the case where prompt_password_async()/

shell_keyring_prompt_cancel() to work as expected in this case.

Commit 4095a58eb9 introduced a

The vvalue and hvalue uniforms are only used to decide whether we
should do fade the edges or not based on the fade_edges uniform.
The result does not change accross fragments so there is no reason
to recompute it for every fragment (pixel) so just split the edge
fade into two uniforms and compute the "should we fade the edges"
boolean once for every direction (when setting the uniforms) instead
of for every single fragment twice.
This reduces the number of uniforms as well as the the number of instructions
which are limited on older hardware. It should also be more efficent.

Gdk uses Xwayland, so it only sees the events we forward to X11

Also, we need to use MetaCursorTracker to handle the cursor

https://bugzilla.gnome.org/show_bug.cgi?id=707467

shell_app_compare() (which is only used as sort function for
shell_app_system_get_running() nowadays) currently takes the
visibility of an app's windows into account, e.g. applications
with visible windows (non-minimized windows on current workspace)
sort earlier than applications without.
This translate traditional window-switcher behavior to applications,
but we stopped sorting by workspace in the app-switcher a while ago,
and with the new auto-minimization behavior of fullscreen windows
it is more confusing than helpful - in fact, since mutter commit
7e61ef09369a we no longer do this for the window list, so it
makes sense to apply the same to application sorting.

In specific cases, GTK+ does not have enough information to set a correct
opaque region, in which the recommended fix is to set your window as

opaque region set, as the plug isn't composited against the socket, but
instead punches through the socket window.

Build gnome-shell for x11, and gnome-shell-wayland for wayland
(as well as the associated libgnome-shell and libgnome-shell-wayland).
The first one links to libmutter, the second to libmutter-wayland.
libgnome-shell and libgnome-shell-wayland are now compiled from
libgnome-shell-base (with all sources that are independent of mutter),
libgnome-shell-menu (with the copy-pasted gtk sources), plus the
sources that use mutter API
https://bugzilla.gnome.org/show_bug.cgi?id=705497
It's mostly equivalent to "jhbuild run gnome-shell", which is

With StBoxLayout using the Clutter layout manager, it will now respect

With the BoxLayout containers in St and Mx and the ClutterBoxLayout
manager, we now have three more or less diverged implementations of
the same layout policy.
While removing StBoxLayout entirely in favor of ClutterLayoutManager
would be the fashionable thing to do, there are obvious drawbacks:
- it is the only actor we have that implements the scrollable interface
- it conveniently exposes its spacing property in CSS
- last but not least, it is used all over the place
So do the next best thing and make our implementation use the
Clutter layout manager internally - that way, the change is
transparent to users, while we get to refer most of the tricky
bits to Clutter. win-win!

This will replace the indicator painted on the stage right now.
This unfortunately does not work for the recorder triggered by the

Commit cfecd063c9 changed the allocation logic to not allocate
scrollbars when the *_visible booleans are false. This breaks the
fade effect as well as the NEVER policy. We do not paint scrollbars
when they are not supposed to be visible, so not allocating them
and thus leaving them in a "needs allocation" state just causes problems.
I am not convinced that it solved any problem to begin with (we don't paint
them anyway).
As the previous condition has basically always been true, just do it
unconditionally.

Chromium (but not google-chrome) has a StartupWMClass in the desktop

Some applications (such as most Java apps, as well as Chrome Web apps) ship

The point of fading the icon is to make the text displayed over the

When the St theme is changed, the StThemeContext unrefs all the theme
nodes cached in it's internal hash table, then emits a signal to
notify all theme nodes that the current theme has changed.
The problem is that the first StWidget to catch a theme changed signal
will trigger a "style-changed" signal catched by its children first.
So the theme changed signal can't be processed properly to cleanup
StThemeNodePaintState before recomputing the theme.
This patch adds a weak ref to the StThemeNode in the
StThemeNodePaintState to ensure paint states are properly cleaned up
when the associated StThemeNode is freed.

Commit 318283fc70 optimized box-shadow rendering by not recreating
shadow materials on every allocation change. Other handles cannot
be reused and are updated regularly, however the patch missed the

https://bugzilla.gnome.org/show_bug.cgi?id=703909
It is the job of layout containers to arrange their children; having
a hidden feature that *also* allows children to be positioned freely
outside the parent's allocation is just odd.
With the last user of the feature gone, kill it.
https://bugzilla.gnome.org/show_bug.cgi?id=703808
Currently the box-shadow is rendering is done like this :
The first time we want to render a node that requires a box-shadow, St
creates an cogl offscreen surface of the size of the allocation and
renders the box into this offscreen buffer using modulation on the
alpha channel, this buffer is then blurred according to the CSS
parameters.
The problem with this method is that every time an StWidget is
resized, its box-shadow offscreen buffer has to be resized and
therefore rendered and blurred.
This patches propose an optimization for this use case by rendering
the box-shadow only once but at a size that is independent of the
StWidget's size. Then every time we need to paint this box-shadow, we
just render this offscreen buffer using a 9-slices.
This method only works when the allocation of the widget is bigger
than the minimum shadow size on which we can apply a 9-slices, that is
given my the radius of the corners. If the allocation is smaller than
this minimum size, we then fallback to the fully render/blur the
shadow (like before this patch).
https://bugzilla.gnome.org/show_bug.cgi?id=689858
The duality of the Clutter's key focus and mutter's window focus has long been
a problem for us in lots of case, and caused us to create large and complicated
hacks to get around the issue, including GrabHelper's focus grab model.
Instead of doing this, tie basic focus management into the core of gnome-shell,
instead of requiring complex "application-level" management to get it done
right.
Do this by making sure that only one of an actor or window can be focused at
the same time, and apply the appropriate logic to drop one or the other,
reactively.
Modals are considered a special case, as we grab all keyboard events, but at
the X level, the client window still has focus. Make sure to not do any input
synchronization when we have a modal.
At the same time, remove the FOCUSED input mode, as it's no longer necessary.

Currently we simply set the gsettings key when activating an input

activates the switch and when the switch is complete, under which key
events are being delivered to applications and interpreted according
to the previous input source.
The patches in bug 696996 introduce a DBus API in g-s-d that allows us
to know when an input source if effectively active. Using that and
freezing keyboard events in the X server until we hear back from g-s-d
we can ensure that events won't be misinterpreted after an input
source switch.

As with the screen recorder, the magnifier already adds its own

The magnifier adds its own copy of the system cursor to apply the

We'll need some of these pieces to be introspectable when we port to

This includes a rename from the G* namespace to the Gtk* one, which

It is currently not always possible to predict the actual output filename
of a recording - the file-template does not necessarily use an absolute

This is OK for fire-and-forget uses like the existing keyboard shortcut,

API might very well need to access the file after the recording. So do
the same as our screenshot API and add an optional (out) parameter to

The shadows are currently rendered by painting the actor we want to
apply shadow on, in an offscreen buffer. The problem is that when this
actor has an allocation padding (ie allocation that isn't at 0x0
relatively to its parent), this padding is added within the offscreen
buffer and as a result the shadow rendering is truncated because the
offscreen buffer size is the size of the allocation box, not the
allocation box + padding.
This patch reposition the actor at 0x0 with rendering it by changing
the initial transformation matrix when rendering the actor offscreen.

In most cases, we'll transition between two states on hover / focus.
Instead of recalculating and repainting our resources on state change,
simply cache the last state when we transition.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
The background image, background image shadow and border image are
allocation-indepedent, so we can keep these in the node. Given that these are
are likely cached in the StTextureCache, the slight increase in code complexity
may not be worth caching these textures and materials -- we might be better off
just computing when we need to paint.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
This ensures that two widgets sharing the same theme node won't trample
on each other's prerendered materials if the actors are of different
sizes. This also tries to be very careful to share as much as possible
during a transition.
This has the side effect that if a widget changes state a bunch of times,
we won't cache every state. Since we expect that state changes are
infrequent and that most cases we'll be able to use the texture cache
to do most of the heavy lifting, this cost is much more insignificant
than rendering a number of different actors with the same theme node
and different sizes.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
Since we now share theme nodes between, we shouldn't cache the paint state
across all nodes. As a first step towards putting this in the actor, split
out the state into another structure. Keep it in the theme node for now
so that we don't make too many changes in one commit.
It's possible that some of these pieces of drawing state could be shared
between theme nodes. For the sake of simplicity, assume that none of them
are shared or should be shared. A future commit could identify those that
could be shared and move them back into the theme node.
