We need to use a GdkPixbufLoader instead of the straightforward

Since rebasing our AppSystem on GLib's facilities, we only ever
append to the id-to-app cache. So if an application is uninstalled,
shell_app_system_lookup_app() will still happily return it if it
was cached previously. For instance if a favorite app is uninstalled,
it keeps lurking in the dash until a restart.
To fix, filter out removed apps from the cache when handling
GAppInfoMonitor::installed-changed.

Currently we update the scale factor on startup and when we get a
monitors-changed signal, which is not the only cases where the setting changes. We cannot listen for gdk-window-scaling-factor changes because it is not
exported to gdk.
So use gtk-xft-dpi which also indicates a scale factor change.
When someone changes gtk-xft-dpi directly without changing the scale factor
we will just re-read the gdk-window-scaling-factor so no harm is done.

While the named commit was correct for VPN connections, it didn't
work correctly for the initial secrets requests like when connecting
to a new access point. In that case, secrets *should* be requested
when none are found, but only if interaction is enabled. The
bits of 17726abb which removed checking secrets against the hints
*were* correct, but 17726abb removed too much.

Currently running the perf tool results into no wm running
afterwards making it hard for the user to get the results from a terminal

So restore the shell after the test has completed.

clutter_device_manager_get_core_device calls XIGetClientPointer, which
requires a round-trip to the server. Since we do this on StWidget
creation, this means a full round-trip for every created StWidget.
Replace this with get_device with the ID of the VCP/VCK, since mutter
doesn't support MPX, and we know this is what the device is.
If the sprite is NULL, like if a Wayland app wanted to hide the cursor,
then we need to hide the ClutterTexture on our side, as ClutterTexture
has no easy way to tell it to paint nothing.
If gdk_screen_get_setting fails, like if it's running without XSettings,
then the GValue will have a value of 0. A lot of code tries to divide by
the scale factor. This produces NaN, and combined with the fact that NaN
is "leaky", we very quickly end up spinning out of control.
jsapi.h has some bad warnings with gcc. gjs-module.h already includes

Since we started tracking non-interesting windows, we can no longer
assume that if we manage to find an app associated with the focus window,
it should appear focused - we now can find apps for docks, the DESKTOP
window etc.
To restore the old behavior, make sure that the focus window or one of
its parents is "interesting".

The log handler can be invoked at bad times, and in particular
it can be invoked from gsignal with the signal lock taken.
At that time, calling into arbitrary high-level APIs can

Instead, only send to telepathy the tp-glib debug messages.
Everything else is in the journal anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=724256
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.
https://bugzilla.gnome.org/show_bug.cgi?id=723308
The code from shell_window_tracker_is_window_interesting() is equivalent
of MetaWindow's skip-taskbar property, so use it to avoid code duplication.
https://bugzilla.gnome.org/show_bug.cgi?id=723308
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.
https://bugzilla.gnome.org/show_bug.cgi?id=722690
It is possible to associate an application's window with a different
application using the transient_for hint. However we currently only
consider the hint in get_window_app() and not when making the original
association, which opens the door to some confusing inconsistencies;
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
association, not just in get_window_app().

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

Since commit 1ebb162a00 moved JS sources into resources,

Specifying the session mode on the command-line doesn't play

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

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

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

For now, simply scan all desktop IDs.

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

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.

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.

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

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!

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).

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

It is the job of layout containers to arrange their children; having

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).

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.

magnifier adds it anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=700488
The magnifier adds its own copy of the system cursor to apply the
expected transformations, so we don't need to add it again in the

but doesn't address the case where the cursor should not be recorded
at all, but the magnifier adds it anyway.

Wrap new GtkMenuTracker API that adds an easy way to bind to

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

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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
We want to put the paint state in the actor rather than in the theme
node, as having two actors with different sizes but the same theme node
is now much less efficient.

The changes from commit b4f5f1e461 and b394d184cc increased the
instructions required for the fade fragment shader. This is over the limit
for some hardware (like intel gen3), which causes the driver to fallback

that has a fade effect takes around 30 (!!) seconds.
So lets go back to the old effect for 3.8 until we find a solution.

Previously when a client requests that a window should be docked the
shell would reparent the socket window onto the stage's window and
then use ClutterX11TexturePixmap to get a texture to represent the
window. This will not work if Clutter is no longer using the X11
winsys for example if it becomes its own display server. Instead this
patch leaves the socket window as a child of the root window and lets
mutter create a MetaWindow out of it. If Mutter is acting as a display
server then this mechanism will still work via the headless x server.
The ShellGtkEmbed instance now registers for notification of the
‘window-created’ signal of the display so that it can find the
MetaWindow that gets created to represent the socket window. When this
window is found it is prevented from being displayed on the screen by
setting the actor's opacity to 0. An input shape is then set on the
window to prevent it receiving any input.
Instead of being a subclass of ClutterX11TexturePixmap, ShellGtkEmbed
is now a subclass of ClutterClone. When the MetaWindow is found for
the socket window the clone's source is set to the invisible actor for
the window so it can be displayed in the panel as before.
The ShellEmbeddedWindow no longer needs to know what the stage is
because it no longer reparents the socket window. Therefore the
ShellTrayManager doesn't need to know the stage either so
shell_tray_manager_manage_stage has been replaced with just
shell_tray_manager_manage_screen.

GdkPixbuf is stored in memory as individual bytes, in strict red-green-blue-alpha

While we were relying on gtk_icon_info_load_icon and friends being

Instead of directly using symbols from GLX to check for the swap event

If you copy a theme node's paint state into itself, it should be an
inexpensive no-op. What actually happened was that we destroyed the
old paint state, re-initialized to blank, then copied the blank state
back into itself. In the process, we lost (for instance) the textures
for rounded corners.
Until I introduced the texture cache, this never actually happened,
because when st_widget_recompute_style() calls st_widget_get_theme_node(),
we'd always get a fresh theme node. Now, we get a theme node T back
from the cache, notice that paint_equal(T, T) is true, short-circuit
slightly by copying its drawing state into itself, and destroy drawing
state that we still needed.
I'm going to fix this in recompute_style() too, but as a general
principle, self-assignment ought to be harmless.

Because we calculate and cache CSS properties once per StThemeNode,

it's advantageous for as many widgets as possible to share a single

(e.g. gaining and losing the :hover pseudo-class), it should ideally
get its original StThemeNode back again when it returns to the old
state.
Here, I'm using the StThemeContext as the location for a cache.

The screen grabber was a workaround for an extremely slow path in Mesa
when reading back pixel data from the frame buffer. It was using pixel
buffer objects by directly calling into GL to hit a fast blit path in
Intel's driver. This should no longer be necessary with the latest
Mesa because the normal read pixels path now has a fast path to just
memcpy the data. Using PBOs in that case just adds an extra
indirection because the data is read into an intermediate buffer and
then copied back out again.
We want to be able to remove the dependency on linking against libGL

by keeping the data of a previous version around indefinitely. For
instance AccountsService will notify of avatar changes, but as new
image is copied over the old one, we will continue to use the old
image data.
Install a file monitor for each file resource we load and clear
the corresponding data from the cache on changes, emitting the
new StTextureCache::texture-file-changed signal.

ClutterText will only queue a relayout after font changes if it has
any contents other than the empty string. As a result, its height
request may change after the first character has been entered. To
avoid this visual glitch, force a relayout on actual font changes.

The actor's GtkIMContext is freed in dispose and reset in unrealize - as
ClutterActor's dispose will unrealize the actor if necessary, chaining
up to the parent after clearing the im context will result in warnings
if the actor is still realized, so chain up first.
