The XSync semantics mandate that alarms already expired will not
fire until the counter is reset and the alarm triggered again, so
clients traditionally called get_idle_time() first to see if they
should install the alarm.
This is inherently racy, as by the time the call is handled by
mutter and the reply received the idle time could be different.
Instead, if we see that the watch would have fired in the past,
fire it immediately.
This is a behavior change, but it's a compatible one, as all legacy
clients are calling get_idle_time() first, and it was perfectly
possible for the idle time counter to trigger the alarm right
after the get_idle_time() call.

To properly resize clients, we need to send them configure events
with the size we computed from the constraint system, and
then check if the new size they ask is compatible with

Note that this does not handle interactive resizing yet, it

Turns out that even if two outputs say that they can be controlled
by a given CRTC, you can't configure them in the same CRTC unless
they are marked as "possible clones" one of the other.

to expose this limitation in the DBus API.

This new interface will be used by the control center and possibly
the settings daemon to configure the screens. It is designed to
resemble a simplified XRandR, while still exposing all the quirks
of the hardware, so that the panel can limit the user choices
appropriately.
To do so, MetaMonitorMode needs to track CRTCs, outputs and modes,
so the low level objects have been decoupled from the high-level
MetaMonitorInfo, which is used by core and API and offers a simplified
view of HW, that hides away the details of what is cloned and how.
This is still not efficient as it should be, because on every
HW change we drop all data structures and rebuild them from scratch
(which is not expensive because there aren't many of them, but
at least in the XRandR path it involves a few sync X calls)

It is a very bad idea in a glib program (especially one heavily
using glib child watching facilities, like gnome-shell) to handle

The previous code was leaving focus fields dirty in MetaWaylandPointer
and MetaWaylandKeyboard at time (which could crash the X server
because of invalid object IDs)
The new code is more tighly integrated in the normal X11 code
for handling keyboard focus (meaning that the core idea of input
focus is also correct now), so that meta_window_unmanage() can
do the right thing. As a side benefit, clicking on wayland clients
now unfocus X11 clients.
For the mouse focus, we need to clear the surface pointer when
the metawindowactor is destroyed (even if the actual actor is
kept alive for effects), so that a repick finds a different pointer
focus.
https://bugzilla.gnome.org/show_bug.cgi?id=705859
This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.
The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.

This breaks down the assumptions in stack-tracker.c and stack.c that
Mutter is only stacking X windows.
The stack tracker now tracks windows using a MetaStackWindow structure
which is a union with a type member so that X windows can be
distinguished from Wayland windows.
Some notable changes are:
Queued stack tracker operations that affect Wayland windows will not be
associated with an X serial number.
If an operation only affects a Wayland window and there are no queued
stack tracker operations ("unvalidated predictions") then the operation
is applied immediately since there is no server involved with changing
the stacking for Wayland windows.
The stack tracker can no longer respond to X events by turning them into
stack operations and discarding the predicted operations made prior to
that event because operations based on X events don't know anything
about the stacking of Wayland windows.
Instead of discarding old predictions the new approach is to trust the
predictions but whenever we receive an event from the server that
affects stacking we cross-reference with the predicted stack and check
for consistency. So e.g. if we have an event that says ADD window A then
we apply the predictions (up to the serial for that event) and verify
the predicted state includes a window A. Similarly if an event says
RAISE_ABOVE(B, C) we can apply the predictions (up to the serial for
that event) and verify that window B is above C.
If we ever receive spurious stacking events (with a serial older than we
would expect) or find an inconsistency (some things aren't possible to
predict from the compositor) then we hit a re-synchronization code-path
that will query the X server for the full stacking order and then use
that stack to walk through our combined stack and force the X windows to
match the just queried stack but avoiding disrupting the relative
stacking of Wayland windows. This will be relatively expensive but
shouldn't be hit for compositor initiated restacking operations where
our predictions should be accurate.
The code in core/stack.c that deals with synchronizing the window stack
with the X server had to be updated quite heavily. In general the patch
avoids changing the fundamental approach being used but most of the code
did need some amount of re-factoring to consider what re-stacking
operations actually involve X or not and when we need to restack X
windows we sometimes need to search for a suitable X sibling to restack
relative too since the closest siblings may be Wayland windows.
This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.
This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.
TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.

This adds a --nested option to request that mutter no longer run as a
classic X compositor with an output window mapped on the X Composite
Overlay Window and also not assume it is running directly under X.
The intention is that in this mode Mutter will itself launch a headless
X server and display output will be handled by Clutter and Cogl. This
will enable running Mutter nested as an application within an X session.
This patch introduces an internal meta_is_wayland_compositor() function
as a means to condition the way mutter operates when running as a
traditional X compositor vs running as a wayland compositor where the
compositor and display server are combined into a single process.
Later we also expect to add a --kms option as another way of enabling
this wayland compositor mode that will assume full control of the
display hardware instead of running as a nested application.
We now track whether a window has an input shape specified via the X
Shape extension. Intersecting that with the bounding shape (as required
by the X Shape extension) we use the resulting rectangles to paint
window silhouettes when picking. As well as improving the correctness of
picking this should also be much more efficient because typically when
only picking solid rectangles then the need to actually render and issue
a read_pixels request can be optimized away and instead the picking is
done on the cpu.
Originally attached dialogs did not have a titlebar, which the code
still assumes though it hasn't been true for a while; nowadays, the
actual look of attached dialogs is controlled by the theme.
As GTK+ recently gained the ability to set custom titlebars, we need
to support attached dialogs with either full borders (WM decorations)
or border-only (GTK+ titlebar).
Just remove the left-over assumption to make it work as expected.

Avoid a round trip to the xserver we already have the current position
anyway. Querying from the server on every move can cause the compositor to
stall during movement.
Add new api (meta_screen_get_current_monitor_for_pos and
meta_screen_get_current_monitor_info_for_pos) that allow querying the monitor
without a roundtrip by reusing the passed in cursor position.
gnome-shell needs to know whether the stage window is focused so
it can synchronize between stage window focus and Clutter key actor
focus. Track all X windows, even those without MetaWindows, when
tracking the focus window, and add a compositor-level API to determine
when the stage is focused.
https://bugzilla.gnome.org/show_bug.cgi?id=700735
When we set the input focus, we first set the predicted window,
and then try to process focus events. But as XI_FocusOut on the
existing window comes before XI_FocusIn on the new window, we'll
see the focus out on the old window and think the focus is going
to nothing, which makes mutter think the prediction failed.
This didn't really matter as nothing paid attention to the focus
window changing, but with gnome-shell's focus rework, we'll try
and drop keyboard focus in events like these.
Fix this by making sure that we ignore focus window changes of our
own cause when updating the focus window field, by ignoring all
focus events that have a serial the same as the focus request or
lower. Note that if mutter doens't make any requests after the
focus request, this could be racy, as another client could steal
the focus, but mutter would ignore it as the serial was the same.
Bump the serial by making a dummy ChangeProperty request to a
mutter-controlled window in this case.

We have no need for normally reported events during grabs. In fact, it
might be harmful. A plugin might grab the keyboard through
meta_begin_modal_for_plugin() and then expect events to be reported to
the grab window they provide. If meanwhile this XIGrabDevice is
issued, events might start being reported normally to one other of our
windows breaking the plugin event processing.
In particular, on an empty workspace, we set input focus to our
no_focus_window. Then, if gnome-shell calls
meta_begin_modal_for_plugin() and meta_display_freeze_keyboard(), in
that order, input events will start being reported to no_focus_window.
There are two issues with this. One is that no_focus_window isn't
selecting for XI input events and thus the server discards them
completely. But even if that is fixed, events being reported to any
window other than the one gnome-shell expects - the clutter stage
window - means that events will stop reaching it.

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

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).

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.

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.

During a resize, if we don't have a configure pending, then a counter
change shouldn't trigger anything other than the normal drawing:
it's just a spontaneous frame from the application. So don't try

Trying to track the fullscreen status outside of Mutter, as GNOME Shell
was doing previously, was very prone to errors, because Mutter has a
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
no longer does anything (not to mention that side-by-side tiled
windows haven't snapped back for a while now).
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
tile previews being shown erroneously on window drag operations
without motion (double-click on titlebar), so reset the tile
mode in maximize().
https://bugzilla.gnome.org/show_bug.cgi?id=682779
The tile preview is expected to be shown underneath the focus window.
However the code that restacks the preview broke when override-redirect
windows were moved to a separate window group.
To fix, special-case tile previews to put them in the NORMAL layer.
https://bugzilla.gnome.org/show_bug.cgi?id=696053
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.
https://bugzilla.gnome.org/show_bug.cgi?id=694046
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.
https://bugzilla.gnome.org/show_bug.cgi?id=694046
Send a _NET_WM_FRAME_DRAWN for each newly created window, as required
by the specification. This avoids a race where a window might be created
frozen but already unfrozen by the time we first see fetch the
counter value.
Remove a duplicate call to meta_compositor_set_updates_frozen() which
was called before the MetaWindowActor is created and hence did nothing.
https://bugzilla.gnome.org/show_bug.cgi?id=694771
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
filter out overlay key press events events at startup (since the shell
isn't normally modal).
This commit changes the code to always run the shell filtering code,
even when the shell is not modal.
https://bugzilla.gnome.org/show_bug.cgi?id=694837
gnome-shell shouldn't announce to the session manager it's
"ready" until it's fully initialized. It currently tells
the session manager it's ready as soon as it hits the main

During compositor grabs, all global keybindings that don't go
through mutter's keybinding system are blocked. To allow other

grab API on DBus; for this, add API to grab key combos directly
instead of parsing accelerators stored in GSettings.

meta_screen_get_monitor_for_rect will return the monitor that

https://bugzilla.gnome.org/show_bug.cgi?id=694725
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.
https://bugzilla.gnome.org/show_bug.cgi?id=688716
Window menus use the first key combination for a binding to show the
acceleration, so the list must be in the right configured order, which

The guard window is effectively the background window, as it sits

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.)
Rename meta_window_sync_actor_position() to
meta_window_sync_actor_geometry() for clarity.
https://bugzilla.gnome.org/show_bug.cgi?id=693922
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
potentially missing _NET_WM_FRAME_DRAWN when an application did a
spontaneous update during an interactive resize and during effects.
Refactor the code to always send _NET_WM_FRAME_DRAWN, even when
a window is frozen.
https://bugzilla.gnome.org/show_bug.cgi?id=693833
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
value. This was causing the frozen state for the window frame counter to
overlap the frozen state for the resize, causing the window not to be
updated.
https://bugzilla.gnome.org/show_bug.cgi?id=693833
In different places we checked the grab op differently when determing
whether we are using _NET_WM_SYNC_REQUEST. This was somewhat covered
up previously by the fact that we only had a sync alarm when using
_NET_WM_SYNC_REQUEST, but that is no longer the case, so consistently
use meta_grab_op_is_resizing() everywhere.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
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
mode because it doesn't look fully utilized.
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
https://bugzilla.gnome.org/show_bug.cgi?id=685463
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
time slices that exceed the frame drawing time, but it's theoretically
right and might make a difference if the X server scheduler is improved.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Resizing the frame triggers creation of a new backing pixmap for the
window, so we should do that first before we resize the client window
and mess up the contents of the old backing pixmap.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
When the application provides the extended second counter for
_NET_WM_SYNC_REQUEST, send a client message with completion
information after the next redraw after each counter update
by the application.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
If an application provides two values in _NET_WM_SYNC_REQUEST_COUNTER,
use that as a signal that the applications wants an extended behavior
where it can update the counter as well as the window manager. If the
application updates the counter to an odd value, updates of the
window are frozen until the counter is updated again to an even value.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Instead of creating a new alarm each time we resize a window
interactively, create an alarm the first time we resize a window
and keep it around permanently until we unmanage the window.
Doing it this way will be useful when we allow the application to
spontaneously generate sync request updates to indicate
frames it is drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=685463
Replace the unused meta_compositor_set_updates() with
a reversed-meaning meta_compositor_set_updates_frozen(), and use
it to implement freezing application window updates during
interactive resizing. This avoids drawing new areas of the window

https://bugzilla.gnome.org/show_bug.cgi?id=685463
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.
(like the one gnome-control-center displays with the monitor name).
Fix that by not calling meta_window_update_for_monitors_changed for OR windows
and let the applications handle them by themselves.
https://bugzilla.gnome.org/show_bug.cgi?id=693540
As the hash table no longer stores only window IDs, we should rename it so

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
hitting the barrier, and lets us "release" the barrier, temporarily
letting the pointer pass through the barrier. These features can be
combined to allow for certain pointer gestures, such as "pushing"
against the bottom of the screen, or stopping the pointer on monitor
edges while dragging slowly for increased edge precision.
This commit should allow graceful fallback if servers with
XInput 2.3 aren't supported.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
Currently, we have a few function wrappers in the shell for pointer
barriers. If we want to implement interactive features on barriers,
we need some sort of signal to be notified of the interactivity.
In that case, we need to make a more sophisticated object-based wrapper
for a pointer barrier. Add one, and stick it in mutter.

This new hint allows compositors to know what portions of a window
will be obscured, as a region above them is opaque. For an RGB window,

clients that use ARGB32 windows to say which part of the window is
opaque, allowing this sort of optimization.

MetaButtonLayout is extremely unfriendly for introspection: its fields
are arrays of a fixed length, but the actual length is determined by
a custom stop value (e.g. not NULL / 0).
Without API changes this will never work nicely in introspection, but

the stop value rather than leaving it at random values.

Currently, we ping windows only when attempting to delete them, but
if the application is not responding, we want to show the dialog
as soon as possible. Given that we cannot be passively notified that
the window stopped responding with the current X11 protocol, a good
workaround is to ping the window when activating it.
If the window stops responding while active, it is expected the user
will try to switch window or open the overview, and when coming back
he'll get the failure dialog.

Since we want nice alt-tab applications for gnome-shell, we should up the

Add an additional "switcher" keybinding for switching between

The window positioning is delayed in idle_move_resize() in case the application
resizes/maximizes its window quickly after its creation. The delayed
positioning uses window->user_rect because of bug 426519 comment 3 (see
meta_window_move_resize_now()).
user_rect was not set in the initial positioning, causing the delayed
positioning unable to know which monitor we use for this window. As a
consequence, the window could jump spontaneously from one monitor to another.
With this patch, the window does not jump anymore.

As the overlay key works differently from normal keybindings, it

Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents

before processing them normally, regardless of whether the compositor
holds a grab or not.

The X server sends a XkbNewKeyboardNotify event for each keyboard

and we are only really interested in changes to the virtual core

When using the show-desktop shortcut with no desktop window, unshowing
will focus the second-most-recently-used window. If we find a desktop
window, it will be focused explicitly and everything works as expected;
however without a desktop window, we end up hiding the focus window,
which will use focus_default_window() with the not_this_one parameter
to move focus away. We used to get away with this, as the not_this_one
parameter was ignored until commit e257580b94, now with bug 675982

On startup, workspaces are initialized according to the num-workspaces

To fix, ignore the preference completely when using dynamic workspaces
and try to restore the previous number of workspaces (as read from

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
application menu from working properly and are visually expensive
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.

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

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

The move-to-corner keybindings weren't treated as user actions, which

We currently sync the number of workspaces with the corresponding

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

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.

When meta_display_unmanage_window_for_screen() is called, it gets a list

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.

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.

meta_window_get_current_tile_area() computes the area where the tiled window
should be based on the current pointer position but that's only meaningful
when the user is actually dragging the window.
When running the tiling constrain the pointer might be on other monitor and at
that point the window jumps to this other monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642580
When using more than one monitor, tiled maximization can be triggered with the
pointer in one monitor while most of the window area remains in another. This
means that the maximization constraint would maximize the window into the wrong

Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.
Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).
Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new

would affect new dialogs, but not existing ones.

There were actually *two* MetaFrameGeometry structs: one in theme-private.h,

casting and int pointers, usually pulling directly from the data in the private
struct.
Remove the public struct, replace it with MetaFrameBorders and scrap all
the pointer hacks to populate it, instead relying on both structs being used
in common code.
This commit should be relatively straightforward, and it should not do any
tricky logic at all, just a sophisticated find and replace.

Since we're not setting the frame's output shape any more, it doesn't
make sense to calculate the output shape based on the frame window.
Instead, track the client window directly and calculate the output shape
based on that.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
In preparation for switching to handling the output shape purely by what we
paint, stop applying a shape to the frame of the window. Even when we restore
handling the output shape, this will change the behavior with respect to input;
transparent areas between the frame and the contents will stop clicks rather
than passing them through, but that is arguably at least as expected
considering how that we decorate shaped windows with a frame all around.

Calling meta_later_add() or meta_later_remove() from within a
META_LATER_BEFORE_REDRAW callback ended up being a no-op, because of
how run_repaint_laters() was fiddling with the laters list. (This
resulted in a crash in window.c:idle_calc_repaint(), which assumed it
would only be called when a certain queue was non-empty, but was
getting called anyway because of a failed meta_later_remove() call.)
Fix this by having run_repaint_laters() work on a copy of the laters
list instead, and add refcounting to MetaLater so that removing a
later that run_repaint_laters() hasn't gotten to yet won't cause
problems.

When we get a press of the overlay key, and then another key is pressed,

When detaching/attaching a dialog, we were only updating
appears-focused on the parent if the child itself was focused, but in
fact, we need to do it if the child has an attached child which is
focused too.
To simplify the case of detaching a focused subtree from its parent,
we change meta_window_propagate_focus_appearance() to use
@window->display->focus_window as the window to add/remove as the
attached_focus_window, and @window only as the starting point to
propagate from. That way we can propagate focus-removal up to
@window's (soon-to-be-ex-)ancestors without having to remove it from

When the _GTK_THEME_VARIANT property changes, rather than just

Since version 3.0, GTK+ has support for style variants. At the moment,

Since appears-focus only propagates up from modal dialogs, if an
application removed the modal hint from a dialog before destroying it,
then its parent would be left with a stray reference to it in
attached_focus_window, causing it to be permanently appears-focused.
The obvious fix, calling meta_window_propagate_focus_appearance() when
the modal hint is removed, tends to cause noticeable flashing, because
the window will get drawn unfocused and then focused again.
So instead we just change meta_window_propagate_focus_appearance() to
check the window type only when focusing in, not when focusing out.
This would also cause flashing, but in this case we can avoid it by
not notifying the change in appears-focus on the parent window if it
is the expected_focus_window (which it will be by this point). (This
does mean though that if something weird happens and the window
doesn't end up becoming the focus window, it won't get redrawn
unfocused until something else forces it to.)

but gnome-shell isn't. gnome-session will handle gnome-shell
crashing, since it's a required component.
https://bugzilla.gnome.org/show_bug.cgi?id=644529
This adds a preference that when enabled makes all windows not on
the primary monitor be visible on all workspaces (i.e. not part of the
workspace switching handling).
https://bugzilla.gnome.org/show_bug.cgi?id=609258
Sometimes on_all_workspaces is requested by the client/user, and sometimes
its calculated implicitly due to internal state. We split this up so that
we know when the user has explicitly asked for sticky window, when e.g.
setting wmspec properties or storing session info.
on_all_workspaces means this window is visible on all workspaces.
on_all_workspaces_requested, means the user explicitly made the window
sticky somehow (via imported session, _NET_WM_STATE from another wm,
toggled in the window menu, etc). It always implies on_all_workspaces is
TRUE.
Right now the only time we set on_all_workspaces is for override-redirect
windows, but later we can add a "windows on non-primary monitor are not
part of the workspace switching" feature.
https://bugzilla.gnome.org/show_bug.cgi?id=609258
We don't actually use the full xrandr to get the primary monitor, we
just rely on the xrandr xinerama compat code to return the primary
monitor first. This lets us avoid adding unnecessary xrandr code and
avoids issues with _NET_WM_FULLSCREEN_MONITORS monitor indexes being
defined wrt xinerama monitor index order.
https://bugzilla.gnome.org/show_bug.cgi?id=609258
The latter move method will place the window by the origin of the
enclosing window decoration/frame, while the former will place by the
origin of the inner window, itself.
(Also moved meta_window_showing_on_its_workspace comment into

https://bugzilla.gnome.org/show_bug.cgi?id=642355
When reload_net_wm_state() is called at startup to read the initial
value of _NET_WM_STATE, it was calling recalc_window_type(), but not
recalc_features(), which meant that, eg, meta->skip_taskbar would
never get initialized from meta->wm_state_skip_taskbar, which meant
that next time mutter went to update the window's _NET_WM_STATE, it
would overwrite the app-specified initial values. Fix that.
(In metacity, this bug is masked by the fact that recalc_features()
gets called when reading the intial value of WM_NORMAL_HINTS, which
comes after _NET_WM_STATE in metacity's prop_hooks_table. In mutter,
the table got reordered at some point, exposing the bug.)
https://bugzilla.gnome.org/show_bug.cgi?id=624360
If mutter is going to be a "real" library, then it should install its
includes so that users can do
#include <meta/display.h>
rather than
#include <display.h>
So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.
There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
Move all of the mutter code into a new libmutter-wm.so, split its
main() method into meta_get_option_context(), meta_init() and
meta_run(), add methods for using in-process plugins, and add
libmutter-wm.pc pointing to the new library.
The mutter binary is now just a tiny program that links against
libmutter-wm. The --version and --mutter-plugins options are handled
at the mutter level, not in libmutter-wm, and a few strange unused
command-line options (--no-force-fullscreen and --no-tab-popup) have
been removed.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
meta_restart() was broken, in that it restarted mutter with what was
left of argv after GOption and Clutter had possibly modified it.
Rather than try to fix this, just remove it.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
Revert the early_initialize changes (which get in the way in the
"libmutter-wm" paradigm), remove the GConf key for setting plugins,
and remove plugin "params", which weren't being used. Also remove all
the logic for unloading and reloading plugins, since the list never
changes after startup now.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
It looks amazingly lame if we simply call exit() during logout. While
it's true that for applications that use XSMP, gnome-session will
close them before us, that doesn't do anything for non-XSMP apps,
which we really hope is the common case.
Instead, we just go away when the X server does.
https://bugzilla.gnome.org/show_bug.cgi?id=643437
For GNOME Shell, we need to grab our DBus names *before* we talk XSMP.
gnome-session takes our XSMP connection as "I'm ready", and starts
running all the other random crud that people dropped in as autostart
files. But for example, we need to have claimed
org.freedesktop.Notifications before a lot of said crud starts.
This requires a plugin API version bump.
Misc: Move handling of --version way earlier in main() where
it should be; no point having it wedged after plugin handling.
If we handle a key event then passing it to GTK+ as well can only
cause confusion. Normally GTK+ would do nothing with a key event for
some window it doesn't know about, but plugins might be doing more
things with the GTK+ event queue.
https://bugzilla.gnome.org/show_bug.cgi?id=642426
If we are previewing hidden windows, we might be previewing them in a context
like a thumbnail view of a workspace where we care about positioning. So, instead
of waiting until the window is first actually shown to place it, if
live_hidden_previews is set, place the window window when we first compute its
visibility, even if we don't end up showing it.
https://bugzilla.gnome.org/show_bug.cgi?id=641309
A plugin that does workspace management on its on may want to set the
workspace layout without having to deal with putting a property
on the root window to be read back and parsed.
Add meta_screen_override_window_layout() that allows the same types
of layouts as _NET_DESKTOP_LAYOUT but without setting a property.
https://bugzilla.gnome.org/show_bug.cgi?id=640552
When we delete a workspace before the active workspace, we need
to upate the _NET_CURRENT_DESKTOP since the active workspace index
changes. To do this workspace.c:set_active_space_hint() is moved
to screen.c:meta_screen_set_active_workspace_hint() so that it
can be shared.

As the tile preview is shown or hidden when a window is dragged
around, it may stick around if the drag operation is cancelled.
Make sure that the preview is hidden in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=639988
Drag operations may be cancelled, in which case the dragged window
should be restored to the position/state it had when the drag was
initialized. In order to do this for tiled states, the original
state has to be saved during the operation.
https://bugzilla.gnome.org/show_bug.cgi?id=639988
The previous tiling state of a grabbed window should be restored
if the drag operation is cancelled (by hitting the Escape key).
This might involve to meta_window_tile(), so export the function
in window-private.h.
https://bugzilla.gnome.org/show_bug.cgi?id=639988
We want switching between the windows of an application to be an easily
accessible operation. The convenient and memorable keybinding is the
key above the tab key - but the keysym for that key isn't consistent
across different keyboard layouts.
Add code that figures out the key from the XKB geometry and a magic
keysym name "Above_Tab" that refers to this key and switch
the default binding for cycle_group to <Alt>Above_Tab. (This will
have no effect for the normal case of getting the key binding from
GConf until this patch is applied to Metacity as well.)
https://bugzilla.gnome.org/show_bug.cgi?id=635569
It may be desirable for theme authors to treat side-by-side tiled
windows differently, for instance to give the edge-touching border
a width of 0, so add additional frame states for tiled windows.
https://bugzilla.gnome.org/show_bug.cgi?id=637330
This patch removes the ability to disable compositing in mutter. As
clutter compositing was the reason for the fork from metacity, turning
compositing off does not make sense.
https://bugzilla.gnome.org/show_bug.cgi?id=626875
To deal with reentrancy from compositor plugins doing things like
moving windows between workspaces in an effect callback, update
the visible_to_compositor flag before calling into the compositor.
https://bugzilla.gnome.org/show_bug.cgi?id=613124
When a compositor is present, we keep the visibility state of the
compositor windows in sync with window->visible_to_compositor. We need
to do the same when enabling the compositor.
https://bugzilla.gnome.org/show_bug.cgi?id=613124
Maximized tiled windows end up with an inconsistent tile mode when
unmaximized by other means than dragging the window free (e.g.
using the unmaximize button or double clicking the title bar), so
reset the tile mode when unmaximizing.
This is not a problem for side-by-side tiling, as there are no
alternatives to dragging the window free.
When a tiled window is maximized (e.g. by clicking the title bar
button), unmaximizing the window restores the tiled state. While
this is reasonable for side-by-side tiling, it is confusing for
"maximize" tiled windows, as unmaximization has no visible effect.
Change unmaximize to only restore the tiled state of side-by-side
tiled windows.
The original patch triggered "maximize" when the window was dragged
to the top, so that the pointer was below or on the monitor edge and
above the work area's top.
If there's no chrome at the top of the monitor, so that monitor edge
and work area top fall together, the pointer cannot be moved above
the work area's top, so tiling was not triggered.
The old behavior of being able to shake loose a maximized window
overlaps with and is for the most part superceded by top edge tiling.
This commit changes the code to only enable shake loose behavior
when edge tiling is disabled.
https://bugzilla.gnome.org/show_bug.cgi?id=630548
In addition to the existing side-by-side tiling modes, this commit
adds a new "maximize" tiling mode. It allows the user to maximize
their windows (in other words, tile with the edge panels) by dragging
their window to the top edge of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=630548
The meta_window_handle_mouse_grab_op_event function ensures
the tile_mode variable is in a consistent state after a drag
op is finished.
The way this is current done is:
if (!window->maximized_vertically &&
window->tile_mode != META_TILE_NONE)
window->tile_mode = META_TILE_NONE;
While valid, it doesn't "read" as well as using the
META_WINDOW_TILED_SIDE_BY_SIDE macro, since the macro is specifically
about side-by-side tiling.
This commit just changes things to use the macro and to not bother
checking the tile mode (since if we just reset it anyway, then it doesn't
matter if the value is right or wrong to begin with).
https://bugzilla.gnome.org/show_bug.cgi?id=630548
Currently, the new tiling feature, supports side-by-side, horizontal
tiling when dragging windows to one of the vertical edges of a monitor.
Other types of tiling (on other monitor edges) are potentially useful,
though.
This commit renames the preference from side_by_side_tiling to
edge_tiling.

A direction parameter is passed to meta_compositor_switch_workspace(),
to indicate the direction of the switch depending on the workspace
layout.
In contrast to the switcher popup, this parameter does not take the
text direction of the locale into account. Change this, so that the
workspace switching animations move in the correct direction.
https://bugzilla.gnome.org/show_bug.cgi?id=636083
overlay_key_combo needs the same treatment as other keycodes on a
change - we should always recompute it if we have a keysym not
a keycode, and not only if the keycode hasn't already been
computed.
Simplify the keymap loading logic by unifying the different
branches; in the reorganization this patch fixes a bug where when
we got a MappingKeyboard event we wouldn't update virtual modifiers
correctly.

* Select for XKB keyboard notification events explicitly; since GTK+
has selected for XKB events, delivery of old-school MappingNotify
events is disabled.
* Fix a bug where once a keycode was loaded for a key binding,

all bindings that have a key symbol rather than a fixed
keycode.

Since we can't distinguish a ConfigureEvent that indicates a raise
from a ConfigureEvent that indicates a move, we get lots of
STACK_OP_RAISE_ABOVE events for windows that are already in the

case.

Add a new frame type META_FRAME_TYPE_ATTACHED which is used for

The theme format version is bumped to 3.2, and attached windows

If no style is defined for "attached", drawing will fall back
to the "border" type.

Now that we create MetaWindow objects for override-redirect windows, we need
to check all key press events to see if they are on GTK+ widgets, not just
events that don't match a MetaWindow. This fixes a problem with alt-Tab stealing
grabs away from the window menu.

While the Meego developers agreed to switching mutter to GTK+-3.0
unconditionally a while ago, Canonical used a GTK+-2.0 build for their
Unity project. As Canonical now announced a switch to compiz as their
window manager, there is no longer a reason to maintain GTK+-2.0
compatibility.
https://bugzilla.gnome.org/show_bug.cgi?id=633133
meta_display_process_key_event() always looks up events based on the
"default" keysym for the keycode, so we should do the same here. This
fixes, eg, the lookup of Shift-Alt-Tab (which would otherwise be
unrecognized because the keysym would be XK_ISO_Left_Tab rather than
XK_Tab).

In many places, MetaRegion was being used entirely internally, rather
than for gtk2/gtk3 compatibility. In these cases, it's simpler to just
depend on cairo-1.10 (for both gtk2 and gtk3) and use cairo_region_t.
The few places where we did need GDK compatibility (GdkEvent.region and
gdk_window_shape_combine_mask) are replaced with a combination of
converting GdkRegion to cairo_region_t and conditional code.
https://bugzilla.gnome.org/show_bug.cgi?id=632474
For functions (but not callback types), '(closure)' is used on the
callback parameter, and takes the name of the parameter which is
the closure/user data.
A maximized window can't be resized from the screen edges (preserves
Fitts law goodness for the application), but it's still possible
to start a resize drag with alt-middle-button. Currently we just
don't let the user resize the window, while showing drag feedback;
it's more useful to let the user "break" out from the resize.
This provides a fast way to get a window partially aligned with
the screen edges - maximize, then alt-drag it out from one edge.
Behavior choices in this patch:
- You can drag out a window out of maximization in both directions -
smaller and larger. This can be potentilaly useful in multihead.
- Dragging a window in only one direction unmaximizes the window
fully, rather than leaving it in a horizontally/vertically
maximized state. This is done because the horizontally/vertically
maximzed states don't have clear visual representation and can
be confusing to the user.
- If you drag back to the maximized state after breaking out,
maximization is restored, but you can't maximize a window by
dragging to the full size if it didn't start out that way.
A new internal function meta_window_unmaximize_with_gravity() is
added for implementing this; it's a hybrid of
meta_window_unmaximize() and meta_window_resize_with_gravity().

The hacks we were playing by calling gdk_error_trap_push() and then
resetting the error handler are incompatible with the rewrite of
GDK error traps.
Since the new error code has some features that simplify what we
are doing (like automatically figuring out whether a XSync() is needed)
and because our custom error handler didn't have a lot of a point,
use a separate code path for GTK+ 3.0 builds that just uses the
GDK error traps straight-up without a custom error handler.

Wine sets _NET_WM_USER_TIME_WINDOW to point to an unmapped toplevel;

When dragging a window over a screen edge and dropping it there,
maximize it vertically and scale it horizontally to cover the
corresponding half of the current monitor.
Whenever a "hot area" which triggers this behavior is entered, an
indication of window's target size is displayed after a short delay
to avoid distraction when moving a window between monitors.

If the user just presses a modifier (e.g., shift) during Alt+Tab grab, we need

When we do pseudo-management on an override-redirect window, we have to be
careful to augment the existing event mask, not replace it, or
delivery of pointer events will be disrupted.
When we unmanage a window, we shouldn't try to unselect events at all,
since that will interfere with event selection done by GDK.

A mismerge of the Metacity commit "4943d79 Prevent window self-maximisation"
caused the window's user set size and position to be saved *before*
actually resizing the window to the unmaximized position rather than after.
This meant that after unmaximization the window was in an inconsistent
state and anything that caused a resize to be queued (like a change in
window properties by the application) would cause it to pop back to
the maximized size and position.

While debugging a focus problem, I noticed that Mutter had exactly
the debug statements I wanted under the META_DEBUG_FOCUS topic.
However, calling meta_set_verbose (true) results in enormous amounts

Changing the number of workspaces via an external pager relies on the gconf
key; if a plugin adds or removes workspaces on the fly, we can get into a
situation when the stale number stored by the preferences matches the new

A per-window _MUTTER_HINTS property allowing plugins to use custom hints. The

Although multi-screen support has not been tested and probably
doesn't fully work, the basic setup for multi-screen is that
we have the same list of plugins for all screens, but a different
instance of the plugins for each screen.
To allow plugins to do setup that is screen independent and needs
to occur early in the setup process, we identify a "default plugin
manager" and load (but not start) that plugin manager's plugins
immediately after we know our list of plugins.
That plugin manager is then reused for the first screen we open
and the plugins are started at that time. Separate plugin managers
are loaded and started for any other screens we open.
(A plugin could keep track of whether the screen-independent
setup has been done in a static variable, or it could do everything
in a way that is safe to do repeatedly.)

Allow a plugin to redirect preferences from one GConf location
to another GConf location. This is useful for keys that need to be
set differently in a plugin-managed environment (like GNOME Shell)

Overriding is implemented by overwriting the keys in the arrays
of preferences; a list of the current overrides is stored to allow
proper memory management when an override is itself overriden.
