If a binding is updated with a clear set of strokes (effectively
disabling it) we aren't signaling that the binding changed and thus
the previous strokes will continue to be grabbed.
This fixes that and tries to do a better effort at checking if the
binding changed or not.

gnome-shell has traditionally just called XSetInputFocus when wanting to
set the input focus to the stage window, but this might cause strange,
hard-to-reproduce bugs because of an interference with mutter's focus
prediction. Add API to allow gnome-shell to focus the stage window that
also updates mutter's internal focus prediction state.

If an app pops up an OR window and sets input focus to it, like
Steam does, we'll think the focus window is null, causing us to
think the app is not focused.
OR windows should not be special if they get input focus, where
the input focus would be set to NULL. Instead, the window should
be marked as focused.

Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.
Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

Make it a static function for now, but this will be a private

Clients using _NET_WM_MOVERESIZE to start a drag operation may encounter
a race condition if the user presses and releases a mouse button very
fast, getting "stuck" in a grab state. While this is easily fixed with
the user pressing the button or hitting Escape as the EWMH spec suggests,
its's still a bit of annoyance for users.
After starting a grab operation, check that the button is actually pressed
by the client, and if not, cancel the grab operation. This prevents the
stuck grab in a race-free way, although it requires an extra round-trip
to the server.
With client-side decorations becoming more popular, the use of
_NET_WM_MOVERESIZE is on the rise, thus this bug is seen more frequently
than before.

As we only had one string-array preference so far, we didn't bother

This essentially just moves install_corners() from the compositor, through
the core, into the UI layer where it arguably should have been anyway,
leaving behind stub functions which call through the various layers. This
removes the compositor's special knowledge of how rounded corners work,
replacing it with "ask the UI for an alpha mask".
The computation of border widths and heights changes a bit, because the
width and height used in install_corners() are the
meta_window_get_outer_rect() (which includes the visible borders but not
the invisible ones), whereas the more readily-available rectangle is the
MetaFrame.rect (which includes both). Computing the same width and height
as meta_window_get_outer_rect() involves compensating for the invisible
borders, but the UI layer is the authority on those anyway, so it seems
clearer to have it do the calculations from scratch.

Trying to track the fullscreen status outside of Mutter, as GNOME Shell

very tricky definition of when a window is set to be fullscreen and
*actually* acting like a fullscreen window.
* Add meta_screen_get_monitor_in_fullscreen() and an
::in-fullscreen-changed signal. This allows an application to
track when there are fullscreen windows on a monitor.
* Do the computation of fullscreen status in a "later" function that
runs after showing, so we properly take focus into account.
* To get ordering of different phases right, add more values
to MetaLaterType.
* Add auto-minimization, similar to what was added to GNOME Shell
earlier in this cycle - if a window is set to be fullscreen, but
not actually fullscreen, minimize.

Since the tile mode is now always reset on maximize(), this code

https://bugzilla.gnome.org/show_bug.cgi?id=682779
We used to restore side-by-side tiling when unmaximizing, so we
kept the tile-mode during maximization. Since commit 10d53fc7d
there's no longer a good reason to do so, and it can result in

Previously, we were handling failure to respond to _NET_WM_SYNC_REQUEST
in the code path for throttling motion events. But this meant that
if a window didn't respond to _NET_WM_SYNC_REQUEST and there were no
motion events - for a keyboard resize, or after the end of the grab
operation - it would end up in a stuck state.
Use a separate per-window timeout to reliably catch the failure to respond
to _NET_WM_SYNC_REQUEST.

During resizing we froze window updates when configuring the
window, and unfroze the window updates when processing the
next resize. This wasn't absolutely reliable, because we might
not have a next resize. Instead tie window freezing more
directly to the current sync request value - a window is
frozen until it catches up with the last value we sent it
in _NET_WM_SYNC_REQUEST.
Testing with unresponsive clients showed that there was a bug
where window->disable_sync once set, would not actually disable
sync, but it *would* disable noticing that the client was
unresponsive for the next resize. Fix that by checking for
->disable_sync before sending _NET_WM_SYNC_REQUEST.

mutter currently only filters the overlay key through the shell
when there is a grab operation and that grab operation belongs to the
shell (because the shell is pushModal'd). This means the shell can't

even when the shell is not modal.

gnome-shell shouldn't announce to the session manager it's

meta_window_is_remote compares a cached copy of the system hostname
with the hostname of the client window
(as presented by the WM_CLIENT_MACHINE property).
Of course, the system hostname can change at any time, so caching
it is wrong. Also, the WM_CLIENT_MACHINE property won't necessarily
change when the system hostname changes, so comparing it with the
new system hostname is wrong, too.
This commit makes the code call gethostname() at the time
WM_CLIENT_MACHINE is set, check whether it's remote then, and cache
that value, rather than comparing potentially out of sync hostnames
later.

We do, in fact, need freezing to affect window geometry, so that
move-resize operations (such as an interactive resize from the
left, or a resize of a popup centered by the application) occur
atomically.
So to make map effects work properly, only exclude the initial
placement of a window from freezing. (In the future, we may want
to consider whether pure moves of a window being done in response
to a user drag should also be excluded from freezing.)

meta_window_sync_actor_geometry() for clarity.

The WM spec requires _NET_WM_FRAME_DRAWN to *always* be sent when
there is an appropriate update to the sync counter value. We were

During resizing, An odd counter value (indicating the beginning of a frame)
shouldn't cause us to redraw and start a new frame, only an even counter

In different places we checked the grab op differently when determing
whether we are using _NET_WM_SYNC_REQUEST. This was somewhat covered

When a client is drawing as hard as possible (without sleeping
between frames) we need to draw as soon possible, since sleeping
will decrease the effective frame rate shown to the user, and
can also result in the system never kicking out of power-saving

Use the amount the client increments the counter value by when
ending the frame to distinguish these cases:
- Increment by 1: a no-delay frame
- Increment by more than 1: a non-urgent frame, handle normally

Use XSyncSetPriority() to prioritize the compositor above applications
for X server priority. In practice, this makes little difference because
the Xorg "smart scheduler" will schedule in a single application for

Resizing the frame triggers creation of a new backing pixmap for the

If an application provides two values in _NET_WM_SYNC_REQUEST_COUNTER,

window are frozen until the counter is updated again to an even value.

Instead of creating a new alarm each time we resize a window
interactively, create an alarm the first time we resize a window

meta_screen_resize calls meta_window_update_for_monitors_changed for all
windows including OR windows when the monitors change (or screen size).
This calls meta_window_move_between_rects for the window which attempts to
move the OR window by calling meta_window_move_resize.
meta_window_move_resize refuses to do anything on OR windows (just returns
for OR windows).
This causes a storm of assert messages when the screen
resolution changes while an OR window is visible.

XInput 2.3 adds support for "barrier events", which let us know when
a pointer barrier has been hit, and when the pointer has stopped

letting the pointer pass through the barrier. These features can be
combined to allow for certain pointer gestures, such as "pushing"

When using the show-desktop shortcut with no desktop window, unshowing

however without a desktop window, we end up hiding the focus window,
which will use focus_default_window() with the not_this_one parameter

Fixes bug #670396. Without this fix the guard window may not
extend over the whole area of the screen after a XRandR
reconfiguration. The effect being that mouse events are
delivered to invisible windows.
Moving focus immediately on crossing events as we currently do
in focus-follows-mouse mode may trigger a lot of unwanted focus
changes when moving over unrelated windows on the way to a target.
Those accidental focus changes prevent features like GNOME Shell's

since we now use a very distinct style for unfocused windows.
Instead, delay the actual focus change until the pointer has stopped
moving.

When changing the overlay-key setting, the change only takes effect
on restart - there are actually two bugs involved:
(1) the test whether the key has changed is located in the
else part of a test for string settings (and overlay-key happens
to be a string settings ...)
(2) with (1) fixed, a change signal is emitted, which triggers a
reload of all keybindings - unfortunately, the actual value
of overlay-key is only read on startup, so the key is reloaded
using the old value
Fix both issues by replacing the custom handling of the overlay-key
with the regular handling of string preferences.

Similar to meta_screen_get_primary_monitor, this returns a monitor index.
The monitor that the pointer is on. The previous private implementation
has been renamed to meta_screen_get_current_monitor_info.

The "multiple plugins loaded at once" strategy was always a big fiction:
while it may be viable if you're super careful, it's fragile and requires
a bit of infrastructure that we would be better off without.
Note that for simplicity, we're keeping the MetaPluginManager, but it only
manages one plugin. A possible future cleanup would be to remove it entirely.

We may not show the backtrace, but it's prohibitly expensive to generate,
so don't. If someone wants a backtrace they can use the appropriate G_DEBUG
environment variable plus GDB.

It is impossible to switch to other windows when keep-on-top is set
for maximized windows; given that keep-on-top is only ever useful
to keep a window visible while focusing a different window, the
current behavior is pointless. So ignore keep-on-top while a window
is maximized.

These queued redraws, which is a problem when we want to know exactly
what changed when we redraw, so we do minimal effort. We're eventually
going to replace the queue_redraw API with something a lot better, so
let's just get these out of the way now.

Require the headers for "XFree86" Xinerama to be present at compile
time. The older "Solaris" Xinerama is only needed for versions of
Solaris where Mutter is unlikely to work. Solaris 10 and 11 include
the XFree86 Xinerama libraries, and apparently that's the only version
that will actually work for Solaris 11, which uses Xorg.

Currently pressing the overlay key only triggers the overview if
no other key is pressed between KeyPress and KeyRelease. Extend
this logic to pointer events, so that KeyPress + ButtonPress actions
are treated explicitly different from "pure" overlay key presses.
In particular, this change allows to re-use the overlay key as mouse
button modifier.

Starting the auto-maximize process on a window like a
META_WINDOW_DESKTOP window that is not maximizable gets placement into
a confused state and eventually results in the window being positioned
at the wrong position (the position that an auto-maximized window would
be restored to.)

When mutter recognizes a full-screen window, it tries to raise it to the top
of the stack. Unfortunately, a recent rewrite of the stack code didn't do
well with raising a window to the top of the stack if the stack wasn't in
a consistent state -- it would crash. Ensure that the stack is in a consistent
state at the top of meta_stack_raise/meta_stack_lower.

Commit 2fc880db switched from focusing the topmost window as the default
window to focusing the MRU window. This was done in alignment with the
introduction of per-workspace MRU lists to avoid problems where the window
stack was inadvertently changed when focusing windows during window switches.
Now that focusing windows don't have as big an impact on the stacking order,
we can revert back to focusing the top window, which is less confusing to the
user.
For now, leave per-workspace MRU lists, as they're a pretty good approximation
of a global MRU list, and it works well enough.

"warning: 'match_tile_mode' may be used uninitialized in this function", it
complains. It thinks it's not unused because of other values of
window->tile_mode, but other complex logic ensures that it can't be
META_TILE_MAXIMIZED, so this is a safe commit.
Windows that have minimum widths larger than the screen can't be maximized,
even though we put them in a maximized state and allow users to do so:
the window just won't change size and position. Fix this by simply not giving
the option to maximize, like what happens for non-resizable windows.

A lot of code did something similar to:
MetaFrameBorders borders;
if (window->frame)
meta_frame_calc_borders (window->frame, &borders);
else
meta_frame_borders_clear (&borders);
Sometimes, the else part was omitted and we were unknowingly using
uninitalized values for OR windows. Clean this up by just testing
for a NULL frame in meta_frame_calc_borders and clearing for the
caller if so.

Since we're going to be evaluating the work area at startup now, we need
to make sure that we don't iterate over workspaces before they're assigned.
The easiest way to do this is to make sure that meta_window_get_workspaces
doesn't crash.

Returns the matching tiled window. This is the topmost tiled window in a
complementary tile mode that is:
- on the same monitor;
- on the same workspace;
- spanning the remaining monitor width;
- there is no 3rd window stacked between both tiled windows that's
partially visible in the common edge.

Windows that start up in a size that is almost as big as the workarea create
extra work for the user (resizing or maximizing) so save the user's time by
detecting such windows and automaximize them.
https://bugzilla.gnome.org/show_bug.cgi?id=671677
Basically we don't really want to create windows that are almost maximized in
size but not actually maximized. This creates work for the user and makes it
very difficult to use and resize manually.
So set the newly unmaximized window size to the previously used size or 80% of the
size of the current workarea (attempting to retain natural aspect ratio if
possible), whichever is smaller.

Some modifiers like NumLock and ScrollLock don't make sense in
keybindings, which is why we ignore them when matching keybindings
to events. We should do the same in Javascript, so add an accessor
function.

The move-to-corner keybindings weren't treated as user actions, which
resulted in them not affecting the saved position - they weren't
always being treated as sticky. Marking them as a user action revealed
bugs in the positioning logic that were hidden by the constraint
code applied to automated moves. Fix those as well. Bug tracked
down by Mariusz Libera.

We currently sync the number of workspaces with the corresponding
preference. This is not really useful with GNOME Shell's dynamic
handling of workspaces, not least as the setting is effectively
ignored. Worse, it will trigger writes to dconf on login, slowing
down startup, so add a setting to indicate that workspaces are managed
dynamically and really ignore the num-workspaces setting when set.

After _unmanage the object is semantically dead even if technically it's not,
so remove the prefs listener here to prevent it being called for a dead
object.
In particular this fixes a crash when starting up gnome-shell with at least
one gimp utility window opened which causes mutter to create a MetaWindow for
it only to immediately get an UnmapNotify afterwards which causes mutter to
unmanage the MetaWindow. Afterwards prefs_changed_callback is called for this
dead MetaWindow and tries to dereference the window->monitor pointer which is
already NULL.
https://bugzilla.gnome.org/show_bug.cgi?id=671087
When meta_display_unmanage_window_for_screen() is called, it gets a list
of windows and iterates over them and unmanages them, but unmanaging a
window with attached modal dialogs also unmanages those attached modal
dialogs (in the normal case, temporarily), so we need to guard against
such cases by ref'ing the windows in the list and checking if they have
already been unmanaged.

For maximized windows, titlebars cannot be used to reposition or
scale the window, so if an application does not use it to convey
useful information (other than the application name), the screen
space occupied by titlebars could be put to better use.
To account for this use case, a setting for requesting that windows'
titlebars should be hidden during maximization has been added to
GTK+, add support for this in the window manager.

The current code requires windows to be resizable to be considered
for tiling, which excludes all maximized/tiled windows. While this
restriction concurs with the desired behavior for edge-tiling, it
feels overly restrictive for keybindings.
As the edge-tiling code in update_move() already ensures the above
restriction, it seems save to remove it from the can_tile_maximized()
function, assuming that windows that are not meant to be tiled or
maximized won't provide a maximize function.

Usually tiling involves a size change and the frame is redrawn
automatically, however this is not the case when switching directly
between left- and right-tiled.
Ensure that a redraw happens in that case as well.

Rather than defining keybindings in static arrays generated at compile
time, store them in a hash table initialized in meta_display_init_keys()

Commit d0910da036 merged the visual-bell/visual-bell-type options,
but the change turned out too disruptive for gnome-control-center /
gnome-shell, so gsettings-desktop-schemas commit a5819b2a4e9 re-added
the separate option.
Move preferences to GSettings, using mainly shared schemas from
gsettings-desktop-schemas.
Unlike GConf, GSettings support is not optional, as Gio is already
