* Use --warn-all, --warn-error
* Fix various broken gtk-doc
* Drop unused shell_get_event_related
* For header defines, we currently require them to end in _H to be skipped
* Drop the no-longer-necessary fix-meta-rectangle.py hack
* Move to the convention of using -private.h for headers that are,
well, private.
* Add shell-wm-private.h
Move shadow helper functions from st-theme-node-drawing to st-private
to make them available to widgets which want to add shadows to internal
actors.
Also add a new helper function for creating the shadow material from a
ClutterActor.
https://bugzilla.gnome.org/show_bug.cgi?id=624384
Reorganize the existing code which parses the -st-shadow property
to allow parsing different shadow properties and add support for
the text-shadow property.
https://bugzilla.gnome.org/show_bug.cgi?id=624384
If a shadow property is inherited from a parent, multiple StThemeNodes
share a common StShadow. It would be possible to use st_shadow_copy()
for this purpose, but proper reference counting is nicer.
https://bugzilla.gnome.org/show_bug.cgi?id=624384
Add basic support for background-position, which only supports absolute
values.
Also don't require an unit to be specified for 0 (because the unit does not
really matter here 0 is 0 regardless of the unit).
https://bugzilla.gnome.org/show_bug.cgi?id=624375
Add st_theme_node_paint_equal() and use that to do two things:
1) Avoid animating transitions where nothing changes.
2) Copy cached painting state from the old theme node to the new
theme node.
https://bugzilla.gnome.org/show_bug.cgi?id=627083
Creating an FBO may be expensive, so we should avoid the operation
if possible. When transitioning between theme nodes, the widget's
opacity is used to paint to the offscreen textures which are blended
together - this means that the textures have to be recreated each time
the widget's opacity changes. It is much more effective to paint the
textures at full opacity and respect the widget's paint opacity when
blending the textures together.
https://bugzilla.gnome.org/show_bug.cgi?id=627085
The current search system uses the OR operator to concatenate search
terms. While results which are matched multiple times sort before
other matches, it is almost guaranteed that adding an additional term
to the search increments the number of results, which is rather
surprising.
https://bugzilla.gnome.org/show_bug.cgi?id=610955
gdk_screen_get_rgb_colormap() has been removed from GTK+; there's
no longer a special visual that is used for drawing true-color
images distinct from the system visual. So, we don't need to
check for it; if the visual isn't the system visual, we just
fall through to the case where we create a new GdkColormap.
The function has been upstreamed as clutter_actor_contains() - with
the switch to clutter-1.4 it is now available to the Shell, so it
is no longer necessary to keep a copy in-tree.
https://bugzilla.gnome.org/show_bug.cgi?id=626512
Add support for the CSS :first-child and :last-child properties to
StContainer, and thus to all containers in St and ShellGenericContainer.
The internal ordering of the container's children is used to determine
the child to which to attach the pseudo class, not the children's
positions. This means that containers where positions can differ from
the ordering (ShellGenericContainer / StGroup) may behave unexpectedly,
so some caution is required.
https://bugzilla.gnome.org/show_bug.cgi?id=625316
When we are manually starting dconf in the case where it can't
be activated via D-Bus, we need to set LD_LIBRARY_PATH in its
environment, since dconf is no longer linked with a rpath.
(Unlike the rest of GNOME, it doesn't use libtool.)
There's an assertion in calculate_gaussian_kernel() to avoid a division
by zero - due to an unnecessary cast from float to int this assertion
is triggered incorrectly for small (but non-zero) values, e.g. a blur
radius of 1px.
Recently, g-ir-scanner got a little stricter with regard to
GSList, marking functions not introspectable if the element
type is not annotated. This fixes a visible JS Error by g-ir
and gdmuser/gdm-user-manager.c
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.
https://bugzilla.gnome.org/show_bug.cgi?id=623429
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.
https://bugzilla.gnome.org/show_bug.cgi?id=621845
"text-align" allows setting the alignment of text, with respect to
other lines and allocated space, without requiring a reference to
the ClutterText (which is private for most widgets).
If not specified, all text is left-aligned.

* Add dconf and dependencies to the moduleset and add
libxml2 dependency to gnome-shell-build-setup.sh

It has probably crossed the line to evil by a mile or so, but here
it is: a Tweener.slowDownFactor replacement used by all animations
without exception.
While at it, update Tweener to use the new setTimeScale() upstream
function instead of adjusting the timeline directly.
https://bugzilla.gnome.org/show_bug.cgi?id=622249
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.
https://bugzilla.gnome.org/show_bug.cgi?id=617917
This is a small memory usage optimization, and cleans up the code.
In particular, this will help for later patches which perform
more substantial operations on running apps.
https://bugzilla.gnome.org/show_bug.cgi?id=621203
Nothing uses ShellOverflowList any more, so remove it. (Even if we
want that sort of functionality again later, we'd want it to be
StWidget-based, and with a name less likely to be confused with
StOverflowBox.)
https://bugzilla.gnome.org/show_bug.cgi?id=621582
This function reads a single image file which contains multiple
images internally.
The image file will be divided using @grid_width and @grid_height;
note that the dimensions of the image loaded from @path
should be a multiple of the specified grid dimensions.
https://bugzilla.gnome.org/show_bug.cgi?id=598349
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
monkey-patch in a Clutter.Actor.contains() for use by javascript, and
then replace all the duplicate implementations with one or the other
of those.
https://bugzilla.gnome.org/show_bug.cgi?id=621197
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.
https://bugzilla.gnome.org/show_bug.cgi?id=619025
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.
https://bugzilla.gnome.org/show_bug.cgi?id=619025
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.
https://bugzilla.gnome.org/show_bug.cgi?id=614131
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.
https://bugzilla.gnome.org/show_bug.cgi?id=620377
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
part of the entry.
https://bugzilla.gnome.org/show_bug.cgi?id=620381
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.
https://bugzilla.gnome.org/show_bug.cgi?id=619083
The preference dialog for the panel clock does not set its gettext
domain, so it's not translated even if though translations are
already available.
Fix by setting the domain in the GtkBuilder file and binding the
domain to the locale directory.
https://bugzilla.gnome.org/show_bug.cgi?id=618873
Currently the size of an StGroup depends exclusively on the group's
children - it should be possible to override this behaviour with
fixed values in the CSS.

Update the GNOME Shell version to 2.31.2, and make corresponding
updates to dependencies:
clutter => 1.2.8
mutter => 2.31.2
gobject-introspection => 0.6.11
gjs => 0.7
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
to a web service. The options for the upload (url, system name, secret
key) are read from ~/.config/gnome-shell/perf.ini.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
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
a complete report.
If this option is not specified, a brief human-readable summary
is printed to stdout instead.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
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.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add a helper function to write a string as UTF-8 to a GOutputStream.
The signature of GOutputStream:
gboolean g_output_stream_write_all (GOutputStream *stream,
const void *buffer,
gsize count,
gsize *bytes_written,
GCancellable *cancellable,
GError **error);
Can't currently be handled by GJS.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add gnome-shell options:
--perf-iters=ITERS"
Numbers of iterations of performance module to run
--perf-warmup
Run a dry run before performance tests
Make a successful run of a performance test return 0 not non-zero,
and handle the difference between that and a 0-exit in normal
usage (meaning replaced) in the wrapper.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Move the code that starts gnome-shell and waits for it to exit
to a function in preparation for running it multiple times when
doing iterations of a performance test.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add some basic statistics for allocated memory based on mallinfo(),
and use that to define two metrics:
usedAfterOverview: bytes used after the overview is shown once
leakedAfterOverview: additional bytes used when the overview is
shown a second time.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add a facility for defining and recording numeric statistics
as performance events
shell_perf_log_define_statistic()
Define a statistic and the corresponding event type
shell_perf_log_update_statistic_[ix]() -
Update the stored statistic value
shell_perf_log_add_statistics_callback()
Add a function called before collecting statistics
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)
https://bugzilla.gnome.org/show_bug.cgi?id=618189
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
without a width, we assigned min-width to ->width, thus effectively
treating it as a maximum.
Just delete that bit.

Starting with gtk-2.20.0 there is a gdk_screen_get_primary_monitor,
which supports querying the primary monitor from xrandr.
But due to a sorting bug and lack of heuristics in the fallback path,
it isn't really useable.
Those bugs are fixed in gtk-2.20.1, so use it when building with
gtk-2.20.1+.

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

Adds the ability to create one or more zoom regions that show magnified or
enhanced views of the desktop. The magnifier provides options for:
* magnification factor,
* four mouse tracking modes common to screen magnifiers,
* 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
.../data/gnome-shell.schemas).
* a DBus API to allow other processes to drive the magnifier as a service.

Add StContainer, which implements the ClutterContainer interface based
on the container methods in st-private and make the existing containers
subclass it.
https://bugzilla.gnome.org/show_bug.cgi?id=613907
To replace all calls to deprecated code, GTK+ 2.20 is required - add
some basic compatibility code, so that is still possible to build the

https://bugzilla.gnome.org/show_bug.cgi?id=618258
With the transition to GTK+ 3.0, direct access to struct members

This bumps the required minimum version of GTK+ to 2.20.
https://bugzilla.gnome.org/show_bug.cgi?id=618258
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
UI calls now) to invoke _focus for the running case, which means
that e.g. the application well will now raise all app windows.
https://bugzilla.gnome.org/show_bug.cgi?id=616051
When creating the directory to store user data, XDG_DATA_HOME is
not guaranteed to exist. Also, the standard mandates permissions
of 0700 for the directory.
https://bugzilla.gnome.org/show_bug.cgi?id=617555
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.

The (optional) spread radius allows to make the shadow bigger without

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
window.)
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.
https://bugzilla.gnome.org/show_bug.cgi?id=591390
With the changes from bug 615586, Mutter now expects a separate start()
method which is called after construction. Move our initialization from
constructed() to start() so it can access the MetaScreen.
https://bugzilla.gnome.org/show_bug.cgi?id=615592
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

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
and manipulating it on the CPU, then loading it back into a texture
was a bit lame.
Clean things up a bit here by loading directly into the CPU, doing
the fading, then creating a texture.
Also cache the faded data in StTextureCache.

The relationship between adjustments and scrollbars and
scrollable widgets was much more complex than it needed to be.
StScrollView: Have the scroll view own a pair of adjustments,
set them on the child on add(), remove unnecessary
change notification signal connections.
StBoxLayout: Remove auto-create of adjustments, just take the
adjustments from the scrollbars and set them on the scrollable
child. Notify for hadjustment/vadjustment properties.
StScrollBar: Notify adjustment property.
StScrollable: Document how adjustment setting works.

* ShellGenericContainer needs to destroy its children in dispose()
* Fix variable naming and excess casts in st_label_dispose()
https://bugzilla.gnome.org/show_bug.cgi?id=612511
StScrollable: Document how to set adjustments
StBoxLayout: Make sure that we always have upper >= lower + page_size,
so that clamping works properly. Set the page_increment to be slightly
less than the page_size so there is some overlap, as is customary.
StScrollView: Remove unnecessary fabs() calls, rewrite expressions
for additional clarity.
https://bugzilla.gnome.org/show_bug.cgi?id=611740
- 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.)
https://bugzilla.gnome.org/show_bug.cgi?id=611740
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.
https://bugzilla.gnome.org/show_bug.cgi?id=611740
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.
https://bugzilla.gnome.org/show_bug.cgi?id=611944
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.
https://bugzilla.gnome.org/show_bug.cgi?id=611750
- Specify a minimum version of clutter-1.2.0
- Switch clutter branch in the moduleset to master
- Replace deprecated cogl_texture/material_unref() with

- Replace cogl_check_extension() with strstr - should be
accurate enough.

It's wrong to do anything that requires looking up a widget's style
before you add the widget to the stage, since its final style may

st_widget_get_theme_node() used to emit a warning in this case, but
many would-be contributors apparently didn't notice. Help them out.

StButton animated the background for button transitions; since these aren't

StTooltip should probably have :vertical and :horizontal pseudo classes

Rather than having ShellTextureCache know about the type of each
item it's caching, this lays the foundation for simply caching
arbitrary string -> CoglHandle.
https://bugzilla.gnome.org/show_bug.cgi?id=607500
For StWidget we want the ability to load raw CoglHandle references
rather than having a big pile of actors backing StWidget.
Several bits of StWidget expect to be able to synchronously load
textures; this is a crutch to support that until we can cleanly
make this asynchronous.
https://bugzilla.gnome.org/show_bug.cgi?id=607500
Brute force merge these two by essentially replacing St.TextureCache
with a (renamed) Shell.TextureCache.
One function was added for convenience, namely "st_texture_cache_load_file_simple".

returned NULL on error but only half the callers actually checked this. This
function is better.

Since shell-slicer.h includes st.h, and that includes
<st/*.h>, we need to add -I $(srcdir) to the command line when
running g-ir-scanner to generate Shell-1.0.gir.
For srcdir != builddir, in the builddir, the st/ subdirectory doesn't
exist, so we can't generate st.h there. Just switch to building st.h
directly in the current directory. (The other option would be to
create a st/ subdirectory in the builddir if necessary; might be a
little cleaner, but this works for now and gets things distchecking.)
Add a 'vshadow' property to StScrollView, which, when turned on,

Previously we were hacking out the vertical scrollbar, this patch
allow us to sanely say in which directions we want to scroll.
Note this patch intentionally changes St to depend on GTK+ in the

st_theme_node_adjust_preferred_width/height now limit the content area
of an actor to the max, if given. (The requested width/height may be
larger to make room for borders, etc.)
https://bugzilla.gnome.org/show_bug.cgi?id=606755
In StBin, StBoxLayout, and StTable, if a child has a potential
allocation that is larger than its preferred size, we give it its
preferred size instead. However, the corresponding
get_preferred_height/width methods were not making the same
assumption, which meant that if we had more width than the widget
wanted, we would allocate it its preferred width, but with the height
that corresponded to the larger width.
Fix this by defining new helpers _st_actor_get_preferred_width() and
_st_actor_get_preferred_height() and using them everywhere. Also, make
StBin and StTable use _st_allocate_fill() rather than having
nearly-identical duplicate copies of the code.

In some situations we might need to look up an application from
a process identifier, such as the notification system where we
will determine application from the message sender.
By calling clutter_actor_get_allocation() in st_widget_recompute_style()
to determine whether to redraw gradients, we triggered a complete
reallocation of the stage for each gradient.
As gradients are processed in st_widget_real_style_changed() anyway, the
additional checks in st_widget_recompute_style() are redundant and can
be removed altogether.

The current way we keep track of skip-paint children is more
difficult than it needs to be, and can lead to subtle bugs.
(For one, the skip-paint state of a child is remembered
when it is removed then added back again, which is completely
unexpected.)
Instead of using weak references to track children, just remove
items from the skip-paint list by overriding the remove() virtual
function of the ClutterContainer interface.
The 'skip_paint' hash table is then destroyed in finalize rather than
dispose since it doesn't hold references to memory any more but just
passively tracks an attribute of the children that are currently in
the container.
https://bugzilla.gnome.org/show_bug.cgi?id=608848
When moving a widget with a gradient, its allocation changes

StButton has an internal animation for the border-image actor, then
it connects to the "completed" signal passing itself as data. However,

Some theme authors have stated interest in radial gradient backgrounds.
The w3c has some draft:
http://dev.w3.org/csswg/css3-images/#radial-gradients
As this is rather complex, we add only some very basic support, which
extends our syntax for linear gradients:
background-gradient-direction: [vertical|horizontal|radial]
Gradients are centered circles, whose size is determined by the closest
side.

Some changes to the way we handle CSS gradients:
* draw without padding, thus interpreting gradients as part of the
background rather than as content
* clip to (rounded) border area
* draw the border along the gradient instead of trying to align the

* use the border_image actor instead of the background_image one

* the shape is not determined by the widget's bounding box,
but by the background-image property

Change "./src/gnome-shell --create-extension" to use "gnome-open"
when opening the newly created .js file, so that it is launched
with the user's preferred text editor, instead of hardcoding gedit.
In case of duplicate infos structures with the same id, the
info structures we get from looking up the id in app_id_to_info
aren't necessarily the same as those we used to match, so we
can't rely on matching to implicitly initialize info->casefolded_name.
Since the name collation key isn't used in matching results,
just in sorting, init it on-demand in the sorting which is also more
efficient.
Move CSS handling of StLabel and StButton for their underlying

In terms of implementation; basically we load extensions from the well-known

The high level goal is to separate the concern of searching for
things with display of those things; for example in newer mockups,
applications are displayed exactly the same as they look in the
AppWell.

lowercasing and normalizing every item over and over.

Rather than having gradients be individually implemented by higher
level JS widgets, move basic gradient functionality into StWidget.
There is prior art in WebKit for CSS gradients:
http://webkit.org/blog/175/introducing-css-gradients/
However, implementing this would be quite a lot of work; all we
need in the Shell design at the moment is basic horizontal/vertical
linear gradients. So, the syntax now supported is:
background-gradient-type: [vertical|horizontal]
background-gradient-start: color;
background-gradient-end: color;

An earlier commit was overzealous in removing (out) annotations;

In a variety of places we're using boxes as data-modeling displays,
and in doing so we often want to either remove the children or

If the space we're allocated is too small for our border + padding

Previously shell_app_remove_window assumed that it was being
passed a window in its list; rather than having callers check
whether a window is interesting and only if so removing it
from the app, just ignore removal of windows we aren't interested
in, like how we ignore addition of windows we already have.
https://bugzilla.gnome.org/show_bug.cgi?id=598502
The behavior in respect to borders matches CSS - the properties set the size of
the content exclusive of the borders (CSS3 box-sizing property - not implemented
here - changes this).
min-width/min-height correspond very closely to the CSS meanings.
width/height are a little different from the CSS meanings - the CSS meaning is
"exactly this size unless overridden by min/max-width/height" - but within the
realm of our layout algorithm, making them control natural size is pretty
close.
This way we can force elements to have a fixed natural or minimum size.

For the purposes of determining which application is focused, don't
skip "uninteresting" windows. The old get_focused_window code

The two parts were mapping windows to applications, and
recording application usage statistics. The latter part
(now called ShellAppUsage) is much more naturally built on top of
the former (now called ShellWindowTracker).
ShellWindowTracker retains the startup-notification handling.
ShellWindowTracker also gains a focus-app property, which is
what most things in the shell UI are interested in (instead of
window focus).
ShellAppSystem moves to exporting ShellApp from more of its
public API, rather than ShellAppInfo. ShellAppSystem also
ensures that ShellApp instances are unique by holding
a hash on the ids.
ShellApp's private API is split off into a shell-app-private.h,
so shell-app.h can be included in shell-app-system.h.
Favorites handling is removed from ShellAppSystem, now inside
appFavorites.js.

The window lists were not being resorted when user-time changed, and
the app list was mistakenly "penalizing" apps for having *any*
minimized windows, rather than for having *only* minimized windows.
https://bugzilla.gnome.org/show_bug.cgi?id=598389
Previously, we had ShellAppInfo, which contains fundamental
information about an application, and methods on ShellAppMonitor
to retrieve "live" information like the window list.
AppIcon ended up being used as the "App" class which was painful
for various reasons; among them that we need to handle window
list changes, and some consumers weren't ready for that.
Clean things up a bit by introducing a new ShellApp class in C,
which currently wraps a ShellAppInfo.
AppIcon then is more like the display actor for a ShellApp. Notably,
the ".windows" property moves out of it. The altTab code which
won't handle dynamic changes instead is changed to maintain a
cached version.
ShellAppMonitor gains some more methods related to ShellApp now.
In the future, we might consider changing ShellApp to be a GInterface,
which could be implemented by ShellDesktopFileApp, ShellWindowApp.
Then we could axe ShellAppInfo from the "public" API and it would
return to being an internal loss mitigation layer for GMenu.

ClutterGroup calls _destroy, but most of St was just calling _unparent.
This caused problems because the DESTROY signal was not emitted
for child elements after destroying a toplevel. Also, in a GC'd
binding it would cause unpredictable lifetime of children.
Some St widgets simply didn't have _dispose at all; implement it.
Note because of the usage of the background_image in StButton,
we can't cleanly destroy it inside the StWidget.

round() is a C99 addition, so causes portability problems:
different C library versions require different #defines to
enable it. So simply avoid using it.
Property enumeration names should correspond exactly to the property names;
in particular the ACTIVE vs :checked disparity was confusing reading the
code.
http://bugzilla.moblin.org/show_bug.cgi?id=6504
Convert the StTable code from StStylable to StThemeNode. The
:row-spacing and :col-spacing GObject properties are converted
into spacing-rows and spacing-columns style properties.
A new interactive test is added for StTable.
https://bugzilla.gnome.org/show_bug.cgi?id=596811
Remove the StTable specific methods to add actors:
st_table_add_actor()
st_table_add_actor_with_properties()
Since they shadow the generic ClutterContainer add_actor() method,
and patch in our add() convenience function as we do for
StBoxLayout.
https://bugzilla.gnome.org/show_bug.cgi?id=596811
Remove the StBoxLayout:spacing GObject property, and instead make
BoxLayout look up the spacing from the CSS style. This makes it
consistent with padding and will allow the use of units. (The
removal of the GObject property entirely instead of making it an
override is consistent with how we handle color, font, padding, etc.)
https://bugzilla.gnome.org/show_bug.cgi?id=596803
Add clutter-text properties to allow getting access to the underlying
ClutterText actor. This corresponds to the get_clutter_text() methods.
The PROP_LABEL and PROP_ENTRY enum values are renamed to PROP_TEXT to
match the names of the properties that they correspond to, and the
properties of StEntry are reordered into alphabetical order.
Based on a patch from Colin Walters
https://bugzilla.gnome.org/show_bug.cgi?id=591245http://bugzilla.moblin.org/show_bug.cgi?id=6313
StBoxLayout: Make consistent that the area scrolled and clipped
to is the content area (excluding borders and padding.) Translate
back appropriately when chaining up so that the parent background
is drawn at the right place and picking on the box (if it's reactive)
picks at the right place on the screen.
clip-to-allocation is removed from StScrollView since it's just
not right - if the child has any non-moving elements, like headers or
borders, it will need to set a narrower clip. And even if the entire
child scrolls, we want to clip to an arrow that excludes the scrollbars.
https://bugzilla.gnome.org/show_bug.cgi?id=595997
When a StBoxLayout is allocated a size less than its natural size,
think "shrink" needs to be divided among the children that have
a smaller minimum size than natural size.
This is done by preferentially shrinking the children that are most
expanded from their minimum size and then increasing that set of
children until we've found enough total shrink.
A new method is used of allocating children at integral sizes - instead
of rounding the per-child extra amount to an integer (which causes
cumulative round-off errors), compute the position as we go along in
floats and round individually for each child widget.
Extend the box-layout test to include of a test of a box being set
to various widths, starting quite narrow.
http://bugzilla.moblin.org/show_bug.cgi?id=6311https://bugzilla.gnome.org/show_bug.cgi?id=595995
If the actor isn't in a stage, then setting up the adjustment
based on the actor's size (which we can't compute) and the
size of the default stage (which isn't relevant), doesn't make
sense. Just use arbitrary default values.
The adjustments will be updated to reasonable values when first
the box is first allocated.
It's not entirely clear to me why we ever want to compute the
adjustment settings this way; perhaps we should always use
default values.
http://bugzilla.moblin.org/show_bug.cgi?id=6307https://bugzilla.gnome.org/show_bug.cgi?id=595996
The CSS specification says that the background extends to the
edge of the border (settable in CSS3 with border-clip), make
BigRectangle match this by computing an "effective border color"
as 'border OVER background'.
(If we don't want this behavior - e.g., to be able to use the
transparent borders as margins, then alternatively transparent
border handling would have to be fixed in st-widget.c, since
prior to this transparent and translucent borders were handled
differently.)
https://bugzilla.gnome.org/show_bug.cgi?id=595993
The current CSS3 border-image is close to a superset of what we were
doing for -hippo-background-image. Woot! rename StThemeImage to
StBorderImage and change parsing to look for:
border-image: <url> <number>...
Rather than
-st-background-image: <url> <length>...
percentanges for the border sizes are not currently supported, neither
are the keywords for handling of the middle part. We always do 'stretch'
for now.
https://bugzilla.gnome.org/show_bug.cgi?id=595990
Use BigRectangle to draw the border and background if there's
a border width or border radius and no border image. (Only
uniform borders are supported for now with some deviations
from the CSS model noted in the comments.)
The background color and image parameters are removed from
StWidget's draw_background() method since they were not used
for StButton (the only current user) and the encapsulation
break that they presented caused some minor problems.
Add a test case for borders, and also use borders to style
the buttons in the 'inline-style' test case.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Rather than repeating the computation of borders in many different
widget subclasses, add helper functions:
st_theme_node_adjust_for_height()
st_theme_node_adjust_preferred_width()
st_theme_node_adjust_for_width()
st_theme_node_adjust_preferred_height()
st_theme_node_get_content_box()
That are used in get_preferred_width()/get_preferred_height() and
allocate() methods to consistently apply the necessary adjustments.
This allows removing the StPadding type.
Queueing a relayout when the borders/padding change is moved from
st_widget_real_style_changed() to the invoking code to allow access
to the old StThemeNode for comparison. (Should this be added as
a parameter to the signal?)
Borders are included in the geometry adjustments, but borders
are not yet drawn.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Add support for parsing and caching the border-radius property.
Different radii for the 4 corners are supported; elliptical corners
are not supported.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Add support for passing an inline-style string when creating a
StThemeNode.
Hook this up to a new 'style' property of StWidget.
Add a test case that demonstrates using this to update font sizes
on the fly.
https://bugzilla.gnome.org/show_bug.cgi?id=595991
ShellTheme replaces both StStyle and ccss_stylesheet_t.
The interface StStylable is replaced by usage of ShellThemeNode.
A concrete node class allows some significant optimizations of property
inheritance that would have been much more difficult to achieve with
the highly abstract pair of StStylable and ccss_node_t.
Some operations that were previously on StStylable (like the
::style-changed signal) are directly on NtkWidget.
Custom properties are no longer registered as param-specs; instead you
call directly into shell theme node to look up a length or color:
shell_theme_node_get_length (theme_node, "border-spacing", FALSE, &spacing);
The dependency on libccss is dropped, while preserving all existing
functionality and adding proper parsing and inheritance of font properties
and proper inheritance for the 'color' property.
Some more javascript tests for CSS functionality are added; workarounds for
a CSS bug where *.some-class was needed instead of .some-class are removed.

To each .c and .h file, add:
/* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */

Fix panel, app switcher, and looking glass to limit themselves to the
primary monitor, and run dialog to limit itself to the monitor
containing the currently-focused window.
The overview is also limited to the primary monitor now (with the
other monitors being blacked out), although the workspaces within the
overview are shaped like the full "screen" (the bounding box of all
monitors). To be fixed later.
https://bugzilla.gnome.org/show_bug.cgi?id=593060
Before, if the texture cache received a request to load say
the themed icon for an application multiple times (as could happen
since we have multiple application displays), it would often create
a thread for each one and in fact, load the pixbuf multiple times.
Avoid this by keeping track of outstanding requests.
https://bugzilla.gnome.org/show_bug.cgi?id=596121
This fixes a regression where we weren't using the correct event
timestamps, because for both of these we were sending an XClientMessage

A previous patch fixed a leak when loading items which shouldn't
be cached, but we also had a leak if two requests for the same
item were outstanding. In that case we load the pixbuf twice,
but should discard subsequent loads when we notice we've already
cached it.
https://bugzilla.gnome.org/show_bug.cgi?id=595321
The menu is needed by the app switcher as well as the overview, so
make it slightly more generic and move the code to appIcon. Also add
support for drawing the menu either to the right of or below the icon.
https://bugzilla.gnome.org/show_bug.cgi?id=590563
When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
https://bugzilla.gnome.org/show_bug.cgi?id=594699
Callers will generally expect _popup and _popdown to be a no-op if
the menu is already in that state; make it so.
Also change the 'popdown' signal to be 'cancelled'; this is
clearer and allows us to avoid having activate also call popdown.
https://bugzilla.gnome.org/show_bug.cgi?id=594699
We have compatibility code which detects from the window title what
an application is. However, the code didn't handle the case where
we discovered by title, but didn't have the expected .desktop file
installed.
When the user click+hold+release over the icon, the effect we want
is for the menu to stick around.
Also, allow the user to mouse over the actual windows and select
them directly. If the user mouses over a window, reflect that in
the menu.
If start_shell() threw an exception before, we'd overwrite it with
an exception in the finally() clause. Handle this and just print a message
and let the exception propagate.
Before Clutter gained accessors for event information, we had
shell_global_ functions. Now that Clutter has them, use them and

When we have multiple windows for an application, implement the following
behavior:
* On click + immediate release, go to the most recently used
* On click, hold for 0.6s, pop up a menu with windows, filtering
the window list to just those windows.
Mouse over on the window list highlights the moused-over window.
Implement this by splitting well item into InactiveWellItem
and RunningWellItem, sharing a base class BaseWellItem.
The application menu code wants to do a popup after a given timeout
while holding. We can implement that by adding a function to
manually break the grab held by the button box.
Freeze+thaw around the hover and pressed property notification on leave
since handlers may want to depend on the pressed state on a hover
transition.
The windows we considered for both the app monitor and the overview
workspaces were the same, but the code was duplicated once in C, once
in Javascript.
On OpenSolaris /usr/bin/python is 2.4; use AM_PATH_PYTHON to find

Only mouse button 1 is supposed to activate button controls; other
mouse buttons should do nothing unless there is a context menu.
Checking the click count is important, since double-clicks will

There's seldom a good justification for connecting to signals on
yourself rather than using the default handler slots in the class.
But in particular using the default handler slots means that
an application can connect to ::button-press-event and get in
before the default handling, to implement a button that does
something on press.
http://bugzilla.gnome.org/show_bug.cgi?id=593503
Add an 'active' property to ShellButtonBox. This allows ShellButtonBox
to be used as a "toggle button". It's up the application to connect
it to the ::activate signal; there's no default handling of this.
(It's seldom that the only time you want to toggle a toggle button
through the user interface, so you need some connection to the backend
data store in any case. Removing the default handling all-together
prevents weird interactions.)
When we have built-in styling for ShellButtonBox the 'active' state
would be one of the elements that would be affect the styling.

This is a Box subclass which adds several signals useful for implementing
"button like" behavior, such as hover and pressed states, as well as
click activation on release.
Instead of starting Xephyr automatically, require --xephyr to be
passed explicitly.
This makes the operation easier to understand and has the benefit
of allowing running in Xephyr mode when some other window manager
(like gnome-shell!) is running. We also want to emphasize that
Xephyr is a development tool, and not a good preview of the
user-interface.
http://bugzilla.gnome.org/show_bug.cgi?id=592881
In both, using our allocation directly for the child is wrong; we
should create a new allocation that's our width and height.
In ShellDrawingArea, also need to chain up to parent.
For Firefox/OpenOffice, right now we have a workaround in the
code where we look at their "title" property. However, we
weren't monitoring that property for changes, and I'm fairly
certain Firefox at least was mapping a window and then very
quickly changing its title after. So we need to handle
dynamic changes.
Split out the wm_class mapping from the title hack. It was
messy and weird to have the two mixed because they're not
at all related, and we're not trying to handle WM_CLASS changes
right now.
Explicitly connect to notify::title in the case where we had
a title fallback. When a title changes, just treat it as
an add+remove.
In the Application Menu area in the panel, hook up to app-added
and app-removed so we get notification of the active app changing.
Clean up the vendor prefix handling a bit, and add "mozilla" so that
we pick up "mozilla-firefox.desktop" from Firefox's (recent?) change
to have a WM_CLASS of "Firefox".
Separate the application monitor logic for "tracking" and "usage tracking".
The first means we associate an application with a window. The second
means we count focus time inside that window, and consider the window
interesting from a user point of view.
(Really, should probably split ShellAppMonitor into two classes along
this line, with the second consuming the first).
For the purposes of counting running applications and returning
the list of open windows for an application, skip not-usage-tracked
windows.
Together this allows us to associate the Nautilus desktop window
with the nautilus.desktop, but not show "File Manager" open all
of the time.
We now have functionality in Mutter to grab the keyboard on behalf
of a plugin. This avoids interactions with the key handling code
in Mutter that could leave the user with an inconsistent state
and no way to get out of it.
src/shell-global.[ch]: Change shell_global_grab_keyboard() and
shell_global_grab_keyboard() to shell_global_begin_modal()
shell_global_end_modal() and call mutter_plugin_begin_modal()
mutter_plugin_end_modal() rather than directly grabbing the
keyboard.
main.js: Call global.begin_modal/end_modal from Main.startModal()
and Main.endModal()
altTab.js; Remove call to Main.startModal() - we're letting Mutter
handle modality for Alt-Tab.
main.js lookingGlass.js overview.js runDialog.js: Rename
Main.startModal() to Main.beginModal() for consistency with
naming in mutter and ShellGlobal.
http://bugzilla.gnome.org/show_bug.cgi?id=590686
If Mutter exits with an exit status of 0, then that most likely
means that it was replaced by another window manager and we shoudln't
try to start the previous window manager and the panel.
(We don't actually know about the panel, but assume that if someone
is replacing us they know what they are doing.)
When Mutter exits with a signal, we know we want to restart.
When Mutter exits with a non-signal non-zero exit status, it's
ambiguous - we could be exiting because we lost the connection to
the X server, or because of a assertion failure in gnome-shell.
We assume the latter; if the X server is gone, all that will happen
is a bit of noise.
To know why Mutter exited accurately, we always wait() and
kill() the Mutter process, and then, if running in Xephyr, clean up
Xephyr afterwards. This has the nice side effect of exiting when
gnome-shell does and not forcing the user to close Xephyr manually.
http://bugzilla.gnome.org/show_bug.cgi?id=591171
The design has smaller icons in two columns. Add a new
custom display to docDisplay for it.
Clean up some of the texture cache handling for recent URIs so
it's not size-dependent, since the dash size is now different
from the default GenericDisplay size.
Use MetaGroup for a window when looking up applications. If
we know the application for a TYPE_NORMAL window in the group,
use that.
However, we aren't always going to know the application for a window. In
that case, create a fake one.
ShellAppInfo has a "transient" flag so we know not to write these
fake apps to the usage file.
Clean up the idle focus handler to better handle the case where
no window is focused, and where we don't want to track the
particular window.
Update track_window to create the fake window.
When a window goes away, we want to delete the usage.
Rewrite shell_app_monitor_get_running_apps to be based
on the window_to_app hash, because that's what has the pointer
to ShellAppInfo*. Before we were looking up all ids through
ShellAppSystem, but that shouldn't be holding a ref to transients.
Change the well display icon to be centered, since our icons for
window apps aren't 48 pixels.
We need to use the -lib variant which in turn uses the
GETTEXT_PACKAGE define, because the default translation
domain is actually mutter, not gnome-shell.
$(builddir) is not a standard automake variable. With autoconf < 2.64
it ends up getting set in every Makefile.in to '.' (because autoconf
defines it), but that is no longer the case for 2.64.
Since $(builddir) was always '.', just use that instead.
Infrastructure for localization; hook up intltool, create po/
and po/POTFILES.in. We need to call bindtextdomain/bind_textdomain_codeset.
Switch to gnome-autogen.sh to call intltool.
If we pass in -1 for both width and height, we'd attempt
to scale the image to 0x0. Don't do that; just avoid
scaling the pixbuf and let ClutterTexture do it for us.
Because of a history of cut and paste, the different enumeration
and marshal generation generation shell snippets were using the
same temporary file names. This caused problems for parallel
builds.
http://bugzilla.gnome.org/show_bug.cgi?id=591474
This is a start at the "Active Appliction Item" component of the
shell design. Currently we just show the currently focused
application. When launching a new application, we show that as well.
The implementation here is not complete; basically when launching
we de-focus the active one, and the application well shows the
most recent startup sequence.
This kind of fails in the case of multiple sequences, and we
also don't correctly de-focus the current window in other
launch paths.
Pass the error variable to g_key_file_load_from_data_dirs in
Shell.AppSystem.get_default().load_from_desktop_file again, and
use a try/catch in places.js.
This fixes Shell.TextureCache.get_default().load_thumbnail so
that it can be used to get thumbnails (with an icon matching
the mimetype or, in the worst case, gtk-file, as fallback) for
items which don't have a GtkRecentlyUsed object. This is needed
for the Zeitgeist integration.
- Avoid error '"iconname" may be used uninitialized in this function'
by initializing said variable to NULL.
- Define shell_util_get_file_description as static (like the other
similar functions) to avoid another compiler error.
- Don't save errors from g_key_file_load_from_data_dirs into the
variable "error" (ie. pass NULL to it instead). Without this,
gnome-shell crashes if the key file can't be found (with message
"Error invoking Shell.load_from_desktop_file: Valid key file could
not be found in search dirs").
- Check the result of the load_from_desktop_file() call in places.js,
as it may be null.
Previously, ShellAppSystem only loaded (and cached) the set of
.desktop files from applications.menu and settings.menu, using
the gnome-menus library. The ShellAppInfo structure was
a "hidden typedef" for GMenuTreeEntry.
But we need to support loading an arbitrary .desktop file. Thus,
refactor the ShellAppInfo into a real struct, with a refcount,
and allow it to point to either a GMenuTreeEntry or a GKeyFile.
Also, in the case where we fail to lookup an icon for an
application, ensure we return a 0 opacity texture.
Use ShellGenericContainer to implement a fully dynamic layout
for the application well. It's still fixed to 4 columns by default,
but no longer requires a fixed width to be passed in on start.
With another chunk of work, it could likely try to adjust to
the case where we can only fit fewer than 4 items in the well.
Remove the border highlighting on mouseover, since that caused
reallocations, and the grid layout isn't trivial.
Delete the unused shell_global_get_word_with function.
For both of these, because of optimizations a few patches ago, we
ended up relying on hash table ordering which caused instability
in the application well among other things. Define an ordering
for both.
The favorites is just the order of the GConf keys, and new items
get appended. In the future we should allow insertion at any
point which the grid could use.
For running applications order, define a new "initially_seen_sequence"
transient variable which is just an monotonically incrementing
integer assigned to an application for the first time we saw it
running in this session. When an application is closed, it's reset.
When exiting from --replace mode, we want to start the new
gnome-panel with a reasonable working directory so that if, you say,
open a terminal from it it doesn't start off in the gnome-shell
directory.
(gnome-shell itself is running in $HOME because mutter changes
directory itself at startup.)

Move the GStreamer initialization from the Javascript code into
shell_recorder_init(). This avoids a dependency on the GStreamer
introspection information and will make it easier to drop the
gir-repository module dependency.
Said function in genericDisplay.js was returning the index of the
actor based upon its position in the entire list, while everywhere
else indexes relative to the currently displayed page were used.
This made actions in the details pane break (bug #590949), so I
replace it with a new function in shell-overflow-list.c,
shell_overflow_list_get_actor_index, which is page based.
Subclass ClutterGroup (to avoid having to implement all of dispose,
raise, lower, add, etc.), and have it proxy the allocation requests
out into signals. We have to group up the two out parameters
into a struct unfortunately.
Included example code in the C file source for now.
The previous application monitoring code was originally designed
to be based on WM_CLASS, which was then resolved on a server.
We have that resolution code locally now, so instead
of saving WM_CLASS data, save application IDs.
Also, inside the WM we have a much better
infrastructure for tracking windows. In particular, rather
than polling, we can just watch for focus notification on
the display, and window add/remove.
Instead of polling XScreensaver, use DBus to watch org.gnome.Session
which already has an idle time watch.
Now there is no polling at all inside the monitor.
When we fail to load a texture, make sure we keep it 0 opacity to avoid
a white square. Also this is useful to avoid the square while loading
a texture asynchronously.
Corresponding with the design, if an application is in a running
state (has > 0 windows open), draw a glow behind the name.
To make the display look a bit nicer, set the width of each item
to be equal to the longest word among all the items.
Make sure that we calculate the next update time correctly.
Store timeout time instead of the timeout delta, so that it doesn't get outdated.
Create a new callback when the time update happens for the original callback.
Make sure last visited time is updated in the details pane by keeping track
of the description actors created for the detail actors.
Add comments to the new functions.
Avoid depending on gdb for replacing an existing panel, since it
requires debuginfo and gdb installed.
Instead we grab the org.gnome.Panel DBus name, using DBus name
replacement semantics.
