Add SHELL_STAGE_INPUT_MODE_FOCUSED, to move the keyboard focus to the
shell without grabbing the keyboard or mouse, and make
stage_input_mode into a GObject property so that (among other things),
callers can tell when MODE_FOCUSED reverts back to MODE_NORMAL.

g-ir-scanner is currently buggy and confuses the Gdk.Rectangle alias
with MetaRectangle. Since this is moderately hard to fix in
gobject-introspection and the fix would conflict with in-progress
changes, work around by doing a 'sed job' on the generated Meta.gir.
https://bugzilla.gnome.org/show_bug.cgi?id=623640
The conversion of GdkRectangle to a typedef for cairo_rectangle_int_t
in GTK+-3 makes it no longer a proper boxed type (it's still registered
boxed, but gobject-introspection doesn't know that.) So, switch to using
MetaRectangle, which is now registered as a boxed type by Mutter.

It has probably crossed the line to evil by a mile or so, but here

Windows are only added to an application if they are considered
"interesting". If we keep it that way, we cannot unconditionally
call _shell_app_remove_window() - applications without interesting
windows are not considered running, so the call crashes the shell.
https://bugzilla.gnome.org/show_bug.cgi?id=622236
Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.
A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.
GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

This is a small memory usage optimization, and cleans up the code.
In particular, this will help for later patches which perform

Nothing uses ShellOverflowList any more, so remove it. (Even if we

This function reads a single image file which contains multiple

The image file will be divided using @grid_width and @grid_height;

The framebuffer setup code can fail, e.g. when the texture used as
color buffer has a height/width of 0. In that case, the call to
cogl_pop_framebuffer() will crash the shell trigger an assert. Add
error checking to fail gracefully.
Add _st_actor_contains() in st-private for use within St, and

Our behavior of reversing the animation when the widget's style
changes back to the previous one is sound. On the other hand, when
there's a change to a new style while a transition is active, we
simply cancel the ongoing transition. Updating the transition
correctly so that the new one starts from an intermediate state
is hard.
Nevertheless, if the style changes before any time of the transition
has elapsed, we should do better than the current behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=621140
First, we were passing an incorrect timestamp to
meta_display_focus_the_no_focus_window - fix that.
The invocation of set_focus_app to the started app there couldn't
really work, because (if the above call had worked) we'd get the
X reply *after* the started app.
What we need to untangle here is the distinction that's now made in
ShellApp between _STATE_STARTING and _STATE_RUNNING. A nice way to
start doing this is to rebase ShellWindowTracker to only be concerned
with app states. Concretely, the current "has windows implies
running" logic now lives just inside shell-app.c.
Rename the app-running-changed signal to be app-state-changed. This
will ultimately be useful so that inside the panel, we can track
the last started app.
https://bugzilla.gnome.org/show_bug.cgi?id=620899
The current code only sets up / updates transitions when the new
node's transition-duration is non-zero. It should cancel an
existing transition if the duration is 0.
It is sometimes desirable to fade smoothly between two styles
instead of changing it abruptly.
Add transitions controlled by the transition-duration CSS property.

StThemeNodes may have properties - namely shadows - which paint
outside an actor's allocation. This is not a problem unless drawing
is redirected to an offscreen buffer, in which case the actually
painted size is needed in advance when setting up the buffer.
Add a convenience method to calculate an allocation large enough to
paint the node.
https://bugzilla.gnome.org/show_bug.cgi?id=619025
Add st_theme_node_equal() - two nodes are considered equal iff they
refer to identical elements, so e.g. .example and .example:hover are
not equal, even if no .example:hover rule exists in the CSS.

Previously we were trying to match up remote windows with local
.desktop files, which is definitely wrong. This patch simply
falls back to the app-from-window case for this; better handling
would need design.
https://bugzilla.gnome.org/show_bug.cgi?id=620855
Separate out the main app view into different sections based on the categories
in the desktop file. The configuration is done via gmenu and the desktop menu
specification, we set XDG_MENU_PREFIX="gs-" on startup, so that gmenu reads
gs-applications.menu, which we install.
There is no support for "submenus" - only the menus directly under
Applications will be displayed as categories.

Currently we only relayout when the screen size changes, this gets
the cases where a monitor gets added/removed but not when the primary
monitor changes.
We need to relayout on all monitor layout changes.
Remove ShellGlobal::screen-size-changed signal as it is no longer used, Gdk is
used to track changes now.
A ShellGlobal::gdk-screen property is added for this purpose.

When hovering over the entry's ClutterText, the entry itself
currently receives a leave event and updates the hover state.
Apply the same logic as StWidget itself to treat children as

Add an event when we receive an event on buffer swap completion; we'll
only get this if Clutter is using the INTEL_swap_event GLX extension,
but it's useful to see the actual timing of video frames.
The recorded event includes the actual timestamp of the swap, since
we are given that in the GLX event - on my system it tends to be
consistently 80-100us before we log the event, but if something was
going wrong in event handling (too much synchronous work), then that
could could show up as a longer delay.
https://bugzilla.gnome.org/show_bug.cgi?id=619516
Currently shadows disregard the overall opacity, so e.g. setting
an ancestor's opacity does not effect the shadow. Fix this by
deferring the setting of the shadow's color until it is painted.
Also move duplicated drawing code from st_theme_node_paint() into
its own function.

The preference dialog for the panel clock does not set its gettext

Typo: 10000000 instead of 1000000 for a million. Also, use
G_INT64_CONSTANT instead of LL for a 64-bit constant, to avoid
extraneous 128-bit arithmetic on 64-bit machines.
Add a command line option to upload the generated performance report

Switch from having separate METRICS and METRIC_DESCRIPTIONS objects
in a perf module to a single METRICS array. This is done so the
perf module can define the units for each metric.
In addition to improving the output in the web interface, the purpose
of having units is to give some clue about how to pick from multiple
values from different runs. In particular, with the assumption that
"noise" on the system will increase run times, for time values we want
to pick the smallest values, while for "rate" values, we want to pick
the largest value.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add --perf-output=<filename> option to gnome-shell that combines
the reports written for each run by the C/Javascript code into

If this option is not specified, a brief human-readable summary
is printed to stdout instead.

When SHELL_PERF_OUTPUT is set, instead of just dumping out the metrics, dump
a more complete report with:
- Event descriptions
- Metric descriptions and value
- Event log
Helper functions shell_perf_log_dump_events() and shell_perf_log_dump_log()
are added to ShellPerfLog to support this. The gnome-shell wrapper is adapted
to deal with the changed report format.

shell_perf_collect_statistics()
Update statistics and record events for them
In addition to the explicit collection, statistics are
recorded at a periodic interval (currently 5s)

We want to be able to summarize the behavior of the shell's
performance in a series of "metrics", like the latency between
clicking on the Activities button and seeing a response.
This patch adds the ability to create a script under perf/
in a special format that automates a series of actions in the
shell, writing events to the performance log, then collects
statistics as the log as replayed and turns them into a set
of metrics.
The script is then executed by running as gnome-shell
--perf=<script>.
The 'core' script which is added here will be the primary
performance measurement script that we use for shell performance
regression testing; right now it has a couple of placeholder
metrics.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
ShellPerfLog provides a way for different parts of the code to
record information for subsequent analysis and interactive
exploration. Events exist of a timestamp, an event ID, and
arguments to the event.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
To support scheduling performance-measurement scripts that want to run
a number of actions in series, add shell_global_run_at_leisure() to run
a callback when all work is finished.
The initial implementation of this is not that accurate: we track
business in Tweener.js via new shell_global_begin_work(),
shell_global_end_work() functions, and we also handle the case
where the main loop is continually busy.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
The API docs for ShellApp claimed it sorted by the last time the
user interacted with the app, but if one closed a window, then
we would fall back to comparing against a possibly much older
timestamp from another window. Fix this by just keeping a
user time per app.
Also clean up the comparison function to explicitly check the state
instead of deferring to the window list.
https://bugzilla.gnome.org/show_bug.cgi?id=618378
The ShellGlobal initialization performs several actions like connecting
to the X server, ensuring directories exist, etc., that are problematic
because we were creating the object even when running the binary for
introspection scanning. During compilation we may not even have X11
available in e.g. autobuilder type environments, and it's just a
bad idea to connect even if we do.
Avoid this by deferring creation of the ShellGlobal object
until the plugin is actually started.
Now that we're initializing things later, remove the connection to
screen changes, and initialize cached ShellGlobal state at the point
when the plugin is set. The root pixmap actor is now sized initially
on creation too. Instead of relying on screen-size-changed being
emitted on startup, explicitly invoke _relayout().
https://bugzilla.gnome.org/show_bug.cgi?id=618371
I have no idea why there existed code that if we saw e.g. min-width

Starting with gtk-2.20.0 there is a gdk_screen_get_primary_monitor,

Passing an explicit width in the wfh case or a height in the hfw case

enhanced views of the desktop. The magnifier provides options for:
* magnification factor,

* positioning the magnified view in one of four screen location, or full screen,
* crosshairs to accentuate the position of the mouse,
* user preferences persistence via GConf (schemas in

* a DBus API to allow other processes to drive the magnifier as a service.

To replace all calls to deprecated code, GTK+ 2.20 is required - add

The StTable code only supports height-for-width. When called in
width-for-height sizing mode, instead of treating the -1 flag
value of 'for_width' as a real width, and requesting all the
children at 1 pixel wide, use the natural width of the table
as the width for determing the height.
Since we can't rewrap in width-for-height mode, we then report
the natural width also as the minimum width of the table.

The design calls for raising all windows for a given app in
certain circumstances; implement this. The new _focus method
raises all windows for the app if it's running.
We further change the _activate method (which a lot of the shell

that e.g. the application well will now raise all app windows.

When creating the directory to store user data, XDG_DATA_HOME is
not guaranteed to exist. Also, the standard mandates permissions

As StEntry handles hover differently depending on whether it is
activated or not, the generic hover support in StWidget is
insufficient. Nevertheless it makes sense to set the hover status
using StWidget methods instead of setting the pseudo class directly.
While the extension system already uses an XDG location (XDG_CONFIG_HOME),
other components use the deprecated $HOME/.gnome2 directory.
Replace both with XDG_DATA_HOME - the existing data (app usage stats,
looking glass history and extensions) is not migrated to the new location.

To avoid visual duplication with the application menu, eliminate
the window menu button. (The window menu can still be accessed by
right-clicking on the title bar, or Alt-right-clicking anywhere on the

This is implemented using the new Mutter facility for GConf key
redirection; we add separate key for 'button_layout' with a default
that omits the menu button.

With the changes from bug 615586, Mutter now expects a separate start()

This patch combines several high level changes which are conceptually
independent but in practice rather intertwined.
* Add a "state" property to ShellApp which reflects whether it's
stopped, starting, or started. This will allow us to later clean
up all the callers that are using ".get_windows().length > 0" as
a proxy for this property
* Replace shell_app_launch with shell_app_activate and shell_app_open_new_window
A lot of code was calling .launch, but it's signficantly clearer
if we call this ".open_new_window()", and later if we gain the ability
to call into an application's menu, we can implement this correctly rather
than trying to update all .launch callers.
* Because ShellApp now has a "starting" state, rebase panel.js on top of
this so that when we get a startup-notification sequence for an app
and transition it to starting, it becomes the focus app, and panel.js
cleanly just tracks the focus app, rather than bouncing between SN
sequences. This removes display of non-app startup sequences, which
I consider an acceptable action in light of the committed changes
to startup-notification and GTK+.
https://bugzilla.gnome.org/show_bug.cgi?id=614755
We can't use gdk_display_get_pointer/gdk_window_get_pointer from gjs
when XKB is active. We already had a wrapper that did the
get-modifier-state part of that, but some places also need the
get-pointer-location part of it. So update our wrapper to return both,
and update js code to use it.
https://bugzilla.gnome.org/show_bug.cgi?id=613428
Also, remove a lot of cruft from genericDisplay.js leftover from
previous St-ifications, and remove the pre-gtk-2.16 hacks from the
status tray in panel.js (which are much less needed with the
nearly-all-black panel anyway).
https://bugzilla.gnome.org/show_bug.cgi?id=614516
The actual changes to shell-menu.[ch] are pretty minimal; most of the
changes there are just style/spacing/indentation.
Also, removed shell_menu_append_separator() since it wasn't needed;
the separators would already have been behaving as intended just
because they were non-reactive.
https://bugzilla.gnome.org/show_bug.cgi?id=614516
Most subclasses override get_preferred_width/height, but if they don't

StThemeNode holds a reference to its parent, but we never released
that reference. This could cause us to hold onto whole chains

Currently shell_global_get_primary_monitor just returns the first screen,
in the list as primary.
This is not always correct as the first screen reported by mutter isn't always,
the first one listed by RANDR.
Use gdk_screen_* to query the monitor information and add a heuristic to prefer
LVDS displays (similar like in done for gnome-panel) to prefer the laptop's
internal screen over external displays.
https://bugzilla.gnome.org/show_bug.cgi?id=608647
Ok, there admittedly wasn't a strong rationale for having it in a

Paint/pick all children, regardless of whether or not they lie within
the content_box. The previous behavior was that a child that was 99%
outside the box would be fully visible, but a child that was 100%
outside the box would be fully hidden. This is somewhat odd, and
doesn't match the behavior of the other St container classes, and at
any rate, the use of clutter_actor_get_allocation_box() for this
optimization was incorrect since it doesn't take into account
transformations (anchor point, rotation, etc) that might cause the
child to be drawn within the content_box anyway.
(For scrolled StBoxLayouts, drawing is still clipped to the
content_box, as before, but will now properly take transformations
into account as well.)

When the window's top-left corner is the same as the monitor's top-left

The idea behind this move is that we have a lot more control over
rendering if StWidget isn't a big pile of actors, and things are

https://bugzilla.gnome.org/show_bug.cgi?id=607500
The hover rewrite added a freeze/thaw_notify to
st_clickable_leave_event() (to match the one already in
st_clickable_enter_event()), which broke code in two places that
assumed "pressed" would still be TRUE when "hover" changed to FALSE.
Fix that by exposing the "held" property as well.
A pointer does not equal to an int on x86_64
(which results into pointer - pointer not being an int either),
fix that by casting the resulting value to an int.
Breakage was introduced by commit 909b5ec43c
If track-hover is set, update the hover property automatically, and
the "hover" pseudo class to match, as StClickable used to do. (Remove
the corresponding code in StClickable). Tweak the tooltip handling to
use track-hover, which also makes it slightly more reliable in the
presence of reactive children, etc.
Since style_class and pseudo_class are space-separated lists of names,
add new methods to add and remove individual names rather than just
re-setting the entire name.
Update existing code to use the new pseudo-class methods where
appropriate. In some cases, this may result in actors having multiple
pseudoclasses where previously they only had one at a time, but there
don't seem to be any visible differences.
(There are some places that could usefully use the new style_class
methods as well, but this patch doesn't change them.)
Also, update test-theme.c to test the new methods.

The way we were loading data into a CoglTexture, then pulling it out

StScrollView: Remove unnecessary fabs() calls, rewrite expressions
for additional clarity.

- Fix existing typos and spacing problems
- Get preferred height, not current height, of shadows
- Let shadows overflow don't clamp them when we have too little space
- Remove a now-unecessary stray MAX()
- Fix up scrollview visibility for the pathological case of no child
- Disconnect from adjustments on remove()
- Don't unset the adjustments on the child on remove(), since they
already existed or were autocreated on add()
(We should what we are doing and set the adjustments of the
scrollbars on the child rather than setting the adjustments of
the child, so we match GTK+'s scrolllable interface, but this
at least makes it consistent instead of a weird mix.)

StScrollable: Document how size negotation now works between the
parent and scrollable child.
StBoxLayout: Adapt to the new contract for how size negotiation
works; in particular, handle being allocated less than the
minimum size when scrolled and treat the minimum size as the
size of the scrolled area in instead of the natural size.
StScrollView: Substantially rewrite with fixes including:
- Implement new size negotation contract; this allows us
to determine scrollbar visibility without having to
connect to the adjustment.
- Implement all ALWAYS along with the existing NEVER/AUTO
- When hiding and showing scrollbars and shadows, don't
hide and show widgets, just turn on and off including them
in pick and paint. This avoids queueing relayouts.
- Cleanups for the code for connecting to adjustments,
for changing policy, and for turning on and off shadows.
scroll-view-sizing.js: New test case for StScrollView, allowing
resizing the scroll view interactively, changing the scrollbar
policies and turning shadows on and off.

When an StScrollView is allocated, allocating the child would
cause the adjustment values to change, which would result in
the scrollbars queueing a relayout, which isn't allowed during
allocation.
To avoid this, instead of queueing a relayout when the adjustment
changes:
- When we have a valid allocation already, just go ahead
and reallocate the children.
- Otherwise do nothing immediately and wait until we get allocated
Because the 'needs_allocation' flag in ClutterActor isn't exposed,
this requires some slightly ugly code to shadow that state locally.

Having StDrawingArea use ClutterCairoTexture causes circularity
problems with sizing - StDrawingArea wants to use its allocation for
the size of the texture, but ClutterTexture wants to use the size of
the texture to determine the requited size.
Avoid this by making StDrawingArea directly use Cairo and CoglTexture;
while doing this, the API is changed a bit for simplicity and to
match our use case:
- Instead of clutter_cairo_texture_create(), we have
st_drawing_area_get_context() to retrieve an already created
context. This can only be called in the ::repaint signal.
- The ::redraw signal is changed to ::repaint so we can have
st_drawing_area_queue_repaint() that doesn't collide with
clutter_actor_queue_redraw()
- ::repaint is now emitted lazily when painting the actor rather
than synchronously at various different points.

- Specify a minimum version of clutter-1.2.0
- Switch clutter branch in the moduleset to master
- Replace deprecated cogl_texture/material_unref() with
cogl_handle_unref()
- Use cogl_clip_push_rectangle() rather than cogl_clip_push()
- Replace cogl_check_extension() with strstr - should be
accurate enough.
