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.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
Currently we simply set the gsettings key when activating an input
source. This obviously introduces a time window, between the event that
activates the switch and when the switch is complete, under which key
events are being delivered to applications and interpreted according
to the previous input source.
The patches in bug 696996 introduce a DBus API in g-s-d that allows us
to know when an input source if effectively active. Using that and
freezing keyboard events in the X server until we hear back from g-s-d
we can ensure that events won't be misinterpreted after an input
source switch.

Doing so causes useless full stage redraws and breaks culling

As pressure barriers need a signalling mechanism to provide
information about when and where they are hit, an object which
provides a signal is a more appropriate abstraction for a pointer
barrier than a functional ID-based approach. Mutter has gained
pointer barrier wrappers, so use its objects instead of ours.

While looking at how the plymouth implementation was built, I was so

MetaBackgroundActor.

The supposed reason for launching the calendar server in a peculiar

Instead of falling back to a set of default values or crashing the

Recent mutter changes made MetaShapedTexture not a ClutterTexture,
but instead a special ClutterActor subclass that implemented the texture-y
bits itself. Use recently introduced API in MetaShapedTexture so that we can
get the raw texture data and spit it out as a PNG.
Use the new meta_shaped_texture_get_image() to get a window's texture data.
meta_shaped_texture_get_image() flattens the image against any mask it may
have, so a screenshot of it should look exactly as it does on the display.

For the Intel drivers, using glReadPixels() to read into client-memory
directly from the frame buffer is much slower than creating a pixel
buffer, copying into that, and then mapping that for reading. On other
drivers, the two approaches are likely to be similar in speed. Create
a ShellScreenGrabber abstraction that uses pixel buffers if available.
Use that for screenshots and screen recording.
https://bugzilla.gnome.org/show_bug.cgi?id=669065
Use the correct clip offsets when taking the screenshot of a window, to
exclude possible invisible borders and to include the case where the

Writting the screenshot to a file can take a relativly long time

thread to avoid the hang.

shell_global_get_memory_info tries to zero initialize the output
parameter with memset, but it passes the wrong size (because of
a missing *). There's no reason to do the memset, though. In the

function returns anyway.
This commit drops the memset call in favor of one explicit 0 assignment
that only gets executed on on atypical platforms.

While I've been trying to make the GC kick in more often, I've decided
it's a better tradeoff to aggressively GC at "leisure", for multiple
reasons.
We can and should revisit this at a later time, but basically:
* The shell doesn't generate *that* much JS data - garbage collection
is very fast here.
* Long periods without GC mean we're not calling free() when we
could, which in turn makes heap fragmentation much worse.
* Ensuring the GC runs at idle makes it much less likely we'll take
a random large GC hit in the middle of an animation.

This commit introduces a "session type" for
gnome-shell. It essentially defines what

looking at the key and appropriately differentiating
the UI will happen in subsequent commits.

shell_global_get() currently implicitly instantiates the shell
global singleton the first time it's called. This means there's
no opportunity to set construction-time properties on the singleton.
This isn't an issue yet, because there aren't any. We will need it
in the future, though, when we grow a --gdm-mode that gets exposed as
a property through the global singleton.
This commit adds a new _shell_global_init() function that must be
invoked before shell_global_get() can be called.

MetaPlugin wraps a bunch of compositor (and plain metacity) methods
that we can just call ourselves, so just do that. (Presumably this
dates back to some ancient time when it was imagined that plugins
wouldn't need access to the full metacity API.)

Rather than constantly asking mutter for the MetaScreen, and then
figuring out the MetaDisplay/Display/etc from there, just keep track
of everything we care about inside ShellGlobal.

Remove ShellGlobal's monitor-related methods, and have
Main.layoutManager provide that information instead. Move

shell_global_get_memory_info() is a new function which extracts a few
global counters we have already, namely glibc's mallinfo, spidermonkey's
JSGC_BYTES, and gjs' counters for boxed/object/etc wrappers.
There is some slight overlap with perf; ultimately though I'd
like this function to do some more extensive analysis, so it wouldn't
be quite the same.
perf is going to be mainly concerned with how big the whole process
over time is; memory_info is for debugging memory leaks.

A new envrionment variable GNOME_SHELL_ENABLE_CLEANUP is added which
causes us to attempt freeing global data. The reason this isn't
enabled by default is that it's a waste of time at best, and at
worst in corner cases could cause crashes which would fill up
crash databases. Better to leave it as a developer-only tool.
Start stubbing out some cleanup in ShellGlobal.

shell-global had become a dumping ground for functions that didn't

Before this change, we displayed dialogs on the monitor containing the

Adding correct annotations to Gio.File.load_contents revealed that gjs
doesn't actually support array+length combinations. For 3.0 this would

If you have XFixes 5 (and corresponding xserver support) then we
add barriers on the panel and in the message tray corner so that

https://bugzilla.gnome.org/show_bug.cgi?id=622655
If the pointer moves on or off the stage while another process has a
grab, we will lose track of it. One example of this is that if you use
a popup menu from a message tray trayicon, the tray will stay up after
the menu goes away, because the shell never saw the pointer leave it.
Add a new method shell_global_sync_pointer() that causes clutter to
recheck what actor is under the pointer and generate leave/enter
events if appropriate.
Of course, we can't actually tell for sure when another process has a
grab, so we need a heuristic of when to call this. Currently we call
it from Chrome._windowsRestacked(), which is not really the right
thing at all, but does fix the menu-from-trayicon case...

Build gnome-shell as a binary linked against libmutter-wm, instead of
a module to be loaded by libmutter-wm. Move the majority of

doesn't discard all the methods that are never called from C.

Unfortunately the evolution-data-server client-side libraries seem to
block the calling thread. This is a major problem as we must never
ever block the main thread (doing so causes animations to flicker
etc.). In the worst case, this problem causes login to hang (without
falling back to fall-back mode) and in the best case it slows down
login until a network connection is acquired.
Additionally, in order to sanely use these evolution-data-server
libraries, GConf has to be involved and GConf is not thread-safe. So
it's not really feasible just moving the code to a separate
thread. Therefore, move all calendar IO out of process and use a
simple (and private) D-Bus interface for the shell to communicate with
the out-of-process helper.
For simplification, remove existing in-process code since internal
interfaces have been slightly revised. This means that the shell is no
longer using any native code for drawing the calendar dropdown.

See commit f2158218bef0c51 in mutter. Basically, we need

in the session gets started.
Note: I intentionally removed the Util.killall bits. I believe that
for notification-daemon at least, if we specify
DBUS_NAME_FLAG_REPLACE_EXISTING, we'll take over the name. Not sure
about notify-osd; if that's still a problem, then what we need to do
is add killing (and possibly respawning) of notify-osd to
"gnome-shell --replace", and not have it embedded randomly in a JS file.

Using clutter_get_current_event_time can result into too old timestamps
when there is no current Clutter or Mutter event, since

the event time of the current event (if any) and CurrentTime otherwise.

The gnome-panel allows the user to hover over a tasklist entry
while draging to activate a minimized or obscured window and drop onto it.

Gjs changed to separate the "basic" API from "embedder" API. Unfortunately

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

in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

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 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().
