The previous notification code was attempting to use the "modified"
boolean returned from set_title_text, but "that boolean doesn't mean
what you think it means". It actually means "I truncated the title".
Just always notify, it's far simpler than trying to compute
when we don't need to, and callers can compress if they really need
to.
mutter-window.c originally grew an #include "window-private.h" for
window->override_redirect, but that was just fixed. However since
then it also ended up relying on a few other minor private bits.
To fix that, add meta_window_is_mapped, promote meta_window_toplevel_is_mapped
to public, and use the public MetaDisplay accessor.
The functionality to propagate errors for other displays to other
a "foreign error handler" was Soeren's compositor and is no longer
being used. Remove it.
(Now that error.h is being installed and scanned, we need to either
do this or add XErrorEvent to xlib-2.0.gir and rename ErrorHandler
to MetaErrorHandler. This way is a bit simpler.)
When we first start up, we do not want to run effects on any pre-exising
windows (this is either the case we are starting up and there are no windows,
or we are replacing an exisint window manager, or worse, we crashed, and we
just want to get to the desired desktop as quick as possible).
Dithered about where to place the check; putting into the plugin manager
reduces the number of places (and files) in which it needs to be done.
It's useful for plugins to be able to get access to the
startup-notification data that Mutter already has. Add
an accessor and change signal when recieve an event.
When window initially maps, use the more recent of NET_WM_USER_TIME and
startup notification timestamps to compare against last known user action to
decide whether to focus the window or not. Once we show the window, clear
the initial_timestamp_set flag, so the startup notification timestamp is not
taken into account again.

We store a pointer to the texture independently of the ClutterContainer
internals, and rely on the pointer remaining valid until we run dispose.
Since we also provide public API to access this pointer, we should not
rely on the reference ClutterContainer holds to ensure that texture will
not be destroyed (e.g., some nasty developer could reparent the texture).
We were freeing the description string in dispose and not setting it to NULL,
thus leaving around a dangling pointer for the duration of the disposal.
This commit moves the free into the finalize vfuction, where it belongs.
Many override-redirect windows (including the Metacity UI windows!)
will have NET_WM_WINDOW_TYPE_NORMAL set on them because of shared
code paths with normal windows in toolkits.
Some current Compositor plugins (default plugin and gnome-shell)
check type == NORMAL to determine if to run effects. While fixing
such plugins to also check if the window is override-redirect is
posisble, it seems cleanest to simply not allow any of the decorated
window types to be set on an override-redirect window and to force
these types to META_WINDOW_OVERRIDE_OTHER. This will prevent other
similar problems from showing up in the future.
http://bugzilla.gnome.org/show_bug.cgi?id=590971
When calculating maximum permissible size of our frame window, we need to
avoid an overflow if the application set its max size hint to INT_MAX.
http://bugzilla.gnome.org/show_bug.cgi?id=590627
As a sideffect of commit a576f7a1ea, override
redirect windows of type _NET_WM_WINDOW_TYPE_NORMAL do not have their
features recalculated during MetaWindow construction (same as regular
windows of type _NET_WM_WINDOW_TYPE_NORMAL), so we need to set the initial
values accordingly.
Although the spec designates some window types as typically used for
override redirect windows, it does not prohibit the use of these with
managed windows, so we should not abort if we encounter one of these.
http://bugzilla.gnome.org/show_bug.cgi?id=583870
As with other events, we want to pass through scroll events (button 4/5 presses)
to the compositor, whether or not they are associated with a particular MetaWindow;
do this by simply falling through to the normal code path instead of
separately delivering the events to the compositor.
http://bugzilla.gnome.org/show_bug.cgi?id=588232
Setting the size of the texture causes the minimum and preferred width and
height values to be fixed at the set value. The normal requisition functions
of ClutterTexture will already report the size of the texture pixmap as the
natural size, but also allow scaling down as needed if less space is
available. We don't need that here, but we want to allow someone to make
a ClutterClone of the texture actor.
With recent changes, Clutter no longer sets up the viewport correctly,
unless it receives ConfigureNotify events. If there is a plugin with
an xevent_filter function, then it's that plugins responsibility to pass
the event to Clutter if it doesn't want it. If there is no plugin,
or the plugin doesn't have an xevent_filter function, then we should
call clutter_x11_handle_event() ourselves.
http://bugzilla.gnome.org/show_bug.cgi?id=589419
When a windows contents or shape changes, we schedule a redraw
with clutter_actor_queue_redraw(); we need to queue the redraw
on the shaped texture rather than on the window actor to support
cloning of just the shaped texture without the shadow: that
is, the shaped is what is really changing and it may be
visible via a clone even if the MutterWindow itself is not
visible.
http://bugzilla.gnome.org/show_bug.cgi?id=589429
MetaPreview is only built into libmutter-private, and not included in
the mutter executable. Linking mutter against libmutter-private was
inadvertently added when the introspection build process was set up,
but isn't actually needed, and if -Wl,-as-needed is added during the
build process, then the libmutter-private dependency will be skipped.
* Don't link mutter (or the test programs) against libmutter-private
* Exclude meta-preview.h from the set of headers we feed into the
introspection build process
Reported by Patryk Zawadzki
http://bugzilla.gnome.org/show_bug.cgi?id=587975
* Make generation of the .gir file work for srcdir != builddir
* Add files to CLEANFILES as needed
* Don't distribute the generated file mutter.schemas
When we are painting a stack of 5-10 maximized windows, the
standard bottom-to-top method of drawing every actor results
in a tremendous amount of overdraw and can easily max out
the available memory bandwidth on a low-end* graphics chipset.
It's even worse if window textures are being accessed over
the AGP bus.
When we have opaque windows, we can go ahead and compute visibility
ourselves (in classic X-server fashion) and use that information to
restrict drawing obscured actors.
* Add MutterWindowGroup - a ClutterGroup subclass with logic
for figuring out obscured regions.
* Add mutter_window_get_obscured_region() to get the region
obscured by that window.
* Add mutter_shaped_texture_set_clip_region() to hint
a clip region to the painting code; this is set based on
the computed visible region of MutterWindowGroup.
* Add tidy_texture_frame_set_needs_paint() to hint that the
paint can be skipped entirely; this is used when we detect
that the window shadow is entirely obscured.
http://bugzilla.gnome.org/show_bug.cgi?id=587344
If we are starting on something other than the first workspace,
meta_compositor_switch_workspace() will be called before
meta_compositor_manage_screen(); guard against that.
Previously, changes to the visibility of a window could be indicated
by meta_compositor_map_window(), meta_compositor_unminimize_window(),
meta_compositor_set_window_hidden(), etc, with the exact behavior
depending on the 'live_hidden_windows' preference.
Simplify this so that visibility is controlled by:
meta_compositor_show_window()
meta_compositor_hide_window()
With an 'effect' parameter provided to indicate the appropriate
effect (CREATE/UNMINIMIZE/MINIMIZE/DESTROY/NONE.)
The map state of the window is signalled separately by:
meta_compositor_map_window()
meta_compositor_unmap_window()
And is used only to control resource handling.
Other changes:
* The desired effect on show/hide is explicitly stored in
MetaWindow, avoiding the need for the was_minimized flag.
At idle, once we calculate the window state, we pass the
effect to the compositor if it matches the new window
state, and then clear the effect to start over for future
map state changes.
* meta_compositor_switch_workspace() is called before any windows
are hidden or shown, allowing the compositor to avoid hiding
or showing an effect for windows involved in the switch.
http://bugzilla.gnome.org/show_bug.cgi?id=582341
* Handling of post-effect cleanups for MutterWindow are
simplified - instead of trying to do different things based
on the individual needs of different effects, we just wait until
all effects complete and sync the window state to what it
should be.
* On unmap, once we destroy the pixmap, we tell ClutterX11Pixmap
that we've done so, so it can clean up and unbind. (The
unbinding doesn't seem to be working properly because of
ClutterGLXPixmap or video driver issues.)
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Clean up mutter_window_effect_in_progress() by removing the
include_destroy parameter which was used only in one place that
could be easily done otherwise. (There was another use in
mutter_window_sync_actor_position() that had no point and looked
unintended.)
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Add a paint function that checks all windows for repair and
shape updates; this:
- simplifies the logic for when a window needs to be repaired
- avoids duplicate work when we get multiple damage effects
- avoids the need to look ahead in the event queue
Instead of relying on repair to implicitly resize the
MutterWindow actor, set the size explicitly when the core
code updates the geometry. (This is needed because we haven't
repaired yet when we start an animation, and the animation
may depend on the size to, e.g., rescale from the center.)
Because the core geometry update happens before we start
maximize/unmaximize effects we need to work around this by
passing both the old and new geometry to the compositor.
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Putting hidden windows in the desktop layer is pointless - in
the desktop layer isn't necessary below all visible windows,
and we are hiding the windows by other means. And the movement
isn't reliable because nothing sets stack->needs_relayer, so
windows can get stuck in the desktop layer after being
rehidden.

The patch adds GLib marshalling code to Mutter, since it's required for the "workspace-switched" signal.
The definition of MetaMotionDirection enum is moved to common.h since it's now used in workspace.c.
A little cleaning is done in workspace.c:meta_workspace_activate_with_focus(), where compositor-specific code is merged with the rest of the function (required to emit signal), removing #ifdefs.

Now that we only have one compositor, there's no reason to access the
compositor functions through a vtable. Remove the MetaCompositor virtualization
and make the clutter code implement the meta_compositor_* functions
directly.
Move the checks for the compositor being NULL from the vtable wrappers
to the calling code (most of them were already there, so just a few
needed to be added)
Note: the compositor is actually hard-coded on at the moment and the plan
is to remove the non-composited code entirely, so the checks are
added only to keep things neat: they have no practical effect.

Since the stack passed to the compositor now accurately reflects
the X stacking order, we need to treat hidden windows (which are
at the bottom of the X stacking order) specially - when the
compositor stacking order is synced, try to keep animating hidden
actors in their old positions in the stack.

With MetaStackTracker, it's no longer necessary to XQueryTree to
get a reasonably-up-to-date view of the server stacking order.
Add some comments explaining unclear aspects of

Don't add override-redirect windows to MetaStack; we shouldn't
be restacking them.
Since we *aren't* stacking the override-redirect windows, we need to
be careful that to ignore them when looking for the top managed
window.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
In order to properly track the stacking order for override-redirect
windows, move meta_compositor_sync_stack() call into MetaStackTracker.
In the new location, we sync the stack as a before-redraw idle function,
rather then using the freeze-thaw facilities of MetaStack. This is
simpler, and also properly compresses multiple stack changes on
notifications received from the X server.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
Wedging override-redirect windows into the constraint code in stack.c
results in Mutter getting confused about the stacking order of
these windows with respect to other windows, and may also in some
cases cause Mutter to restack override-redirect windows.
core/stack-tracker.c core/stack-tracker.h: MetaStackTracker - combine
events received from the X server with local changes we have made
to come up with the best possible idea of what the stacking order
is at any one point in time.
core/screen.c core/screen-private.h: Create a MetaStackTracker for
the screen.
core/display.c: Feed relevant events to MetaStackTracker
core/frame.c core/screen.c core/stack.c: When we make changes to the

Override-redirect windows should not be moved or resized by the

- Mark override-redirect windows as already placed to avoid
placing them when first shown.
- Don't move-resize newly created override-redirect MetaWindow
- Don't queue a resize on override-redirect windows when reading
their WM_TRANSIENT_FOR hint.

unexpected code paths that might result in override-redirect
windows being moved or resized.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Normally a window that is "on all workspaces", is also on a particular
workspace (to deal with being unstuck.) This is pointless for
override-redirect windows.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Don't include override-redirect windows when iterating the windows
in the screen. We don't need them for any of the current uses:
- Queueing redraws and resizes on managed windows
- Checking which windows should be added to a new workspace
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Don't include override-redirect windows in the list return by
meta_display_list_windows(), since we almost never want to handle
them when considering "all window" for the display. Add a separate
meta_display_list_all_windows() that includes override-redirect
windows.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Skipping handling of properties for override redirect windows has
two advantages: first it reduces the amount of work needed to get
an override-redirect window (menu, tooltip, drag icon) onto the
screen. But more importantly, it reduces the number of code-paths
for an override-redirect to get into some code portion where it
isn't expected.
* Integrate the list of properties we load initially with the
list of property hooks; this avoids having two separate lists
that we have to keep in sync.
* Add a flag to MetaWindowPropHooks to indicate whether the
property should be handled for override-redirect windows;
currently we load a) properties that identify the window -
useful for debugging purposes b) WM_TRANSIENT_FOR (could be
used to associate menus with toplevels.)
* For properties that aren't always loaded through window-props.c,
add !window->override checks to places that trigger loading,
and add g_return_if_fail(!window->override) to the load
functions as a double-check.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Add g_return_if_fail() to check that window-management functions like
meta_window_maximize() aren't called on override-redirect windows.
This reveals that were were "unminimizing" override-redirect windows
when adding them; avoid doing that.

This reverts commit 16d49695ad.
If we want an actor to go away deterministically, we should call
clutter_actor_destroy(); using unparent instead a) may result
leaks through cyclic ref counts, and b) will delay the deallocation
of the window texture in a garbage collected environment until
the next garbage collection, causing much greater transient use
of memory.

info->pending_input_region needed to be destroyed in
mutter_set_stage_input_region() before it was set to something
else or before it was reset to be full screen (region == None).
Set the initial input area to an empty region by
setting info->pending_input_region to an empty region by default
and setting it to None or a new region if a new input region is
specified.
Remove show_overlay_window() function that was used to set an empty
input region on start-up, and uses a call to do_set_stage_input_region()
with info->pending_input_region as an argument instead.
When we add a window and it gets hidden as the first thing, we need
to show not just the frame window, but also the window itself.
Otherwise when the window subsequently becomes visible, it will
just be an empty frame.

Code:
All references in the code not related to themes, keybindings, or
GConf were changed from 'metacity' to 'mutter'. This includes, among other
things, strings, comments, the atoms used in the message protocol, and
the envvars used for debugging. The GConf schema file was reduced to
the 3 settings new to mutter.
The overall version was brought up to 2.27 to match current gnome.
Structure:
All files named '*metacity*' were renamed '*mutter*' with appropriate
changes in the automake system. Files removed are
doc/creating_themes, src/themes, doc/metacity-theme.dtd,
metacity.doap. These files will eventually end up in an external
gnome-wm-data module.
Installation location:
On the filesystem the mutter-plugindir was change from
$(libdir)/metacity/plugins/clutter to just $(libdir)/mutter/plugins.
The mutter-plugins.pc.in reflects these changes.
Note:
mutter.desktop.in and mutter-wm.desktop both continue to have
X-GNOME-WMSettingsModule=metacity set. This allows
gnome-control-center to continue using libmetacity.so for
configuration. This is fine since most the general keybindings and wm
settings are being read from /apps/metacity/* in gconf.

It doesn't make sense to allow the window texture to be sliced,
but not allow the mask texture to be sliced. So, we should either
set 'disable-slicing' for the texture actor or not pass NO_SLICING when
creating the mask texture.
While slicing currently results in only the first layer being shown,
disabling slicing entirely would break windows larger than the texture
size limit. It would be straightforward to support multitexturing of
sliced textures in Cogl when all the textures are identically sized
and sliced identically, if it became a priority.

Rather than trying to reverse-engineer what kind of tab/workspace

Always compile the default keybindings into Metacity, and if we

we may want to also take some of these keybindings (e.g. Super+TAB)
though.

Add sigals to MetaWorkspace to allow tracking when windows are added

been notified of the new window.)

To guard against CompositeNameWindowPixmap failing, just use an

occured during the error trap. This way is more correct and more

When the window being hidden/mimimized has focus, is modal, but is not on the

the active workspace).
Creating the gard window when constructing MetaScreen causes the screen to
go black for the duration of Metacity startup which is uggly. We do not

the overlay window is only created just before we are ready to show the
stage.
The significant impact of this change is that plugins cannot manipulate the
overlay window during their initial loading, i.e., they cannot call the
input-region API (the plugin should hook into the "show" signal if it needs
to do anything of this sort).
The commit also removes the XClearArea() call on the overlay window that
seems to have served no real purpose.
In particular, make it so that we call meta_compositor_add_window() on
a new window before calling meta_compositor_sync_stack() to position
it. The list returned by mutter_plugin_get_windows() is only updated
by sync_stack(), but sync_stack() only pays attention to windows that
add_window() has already been called on. So without this change, a
newly-mapped window will not be returned by
mutter_plugin_get_windows() until after the *next* restacking.

Once the window destruction is initiated, we can still manipulate our
MutterWindow with clutter API, but we can not longer use any X-based API,
or MetaWindow API to query it.
by iteration over an array. Saves ~44us per window, but
also makes the code cleaner.

GtkStyle is specific to a particular colormap. Metacity
uses different colormaps for windows with different
visuals, so it must specialize the GtkStyle.
Closes#568365 and #513944.
* src/ui/frames.[ch]: Keep a GtkStyle for each MetaUIFrame, which is
obtained by calling gtk_style_attach() on the style for the
MetaFrames. When the style of the MetaFrames changes, reattach
everything. When we call gtk_style_set_background() pass in the
right style.
* src/ui/themes.[ch]: Create a _with_style() variant of functions that
previously took the style from widget->style passed in, so we
can draw with the right style for the colormap.

window property handlers. The ones which remain don't
actually look up the new value in the ordinary way, and
so are a little trickier to merge. Added an "initial"
flag to be on the safe side that the behaviour is the
same as before (so we don't do things when a window's
first mapped that we only used to do when a property
changed). Partial fix for bug #549886.

Add 'hide_after_effect' flag to MutterWindowPrivate, tracking
whether the window needs to be hidden after all outstanding effects
finish.
Set or clear the flag as appropriate in clutter_cmp_set_window_hidden.
In mutter_window_effect_completed, if hide_after_effect is TRUE
and no other effects are in progress, hide the window.
When there is custom handler installed for the tab releavant tab function
we do not want to actually call it form inside of this function, only to
ensure that the grab is not released. The handler will get called in the
normal way in process_event(). Whoever installed the handler (and requested
the grab) also has to ensure the grab is released.
Requiring the compositor private object to be a GObject allows the
return value of meta_window_get_compositor_private() to be used
via gobject-introspection, since the type and memory management
can be determined.
This allows a reverse mapping from MetaWindow to MutterWindow.
- Change meta_window_get/set_compositor_private to use GObject
rather than void *
- Adapt code in compositor-mutter.c to match.
Now that Cogl has the material API we can use Cogl calls for
multi-texturing instead of directly calling GL.
The MutterShapedTexture actor keeps a handle to a material with the
right combine modes for combining the texture and the shape
mask. Before each paint it sets the layers of the material to be the
two textures.
A second material with different combine modes 1is also created if the
pixmap is 24 bit to implement the workaround from commit 72da8c57.
It seems that with the latest intel drivers when multi-texturing using an RGB
TFP texture, the texture is being setup internally as an RGBA texture, where
the alpha channel is mostly 0.0 so you only see a shimmer of the window. This
workaround forcibly defines the alpha channel as 1.0. Maybe there is some
clutter/cogl state that is interacting with this that is being overlooked,
but for now this seems to work. (Tested on i945 + DRI2)

The addition of method implementations in the base class in the
plugin-gobject branch broke the logic for checking to see
if a plugin didn't implement an effect. Requiring a mandatory
chain up to the base class is a fiddly anyways, so this patch
does the 'running' count computations in a different (and more
robust) way.
mutter-plugin.h mutter-plugin.c: Add _mutter_plugin_effect_started()
to increment the running count.
mutter-plugin-manager.c: Call _mutter_plugin_effect_started()
as necessary.
mutter-plugin.c: Remove the "real" methods that did nothing
but implement the runnning count.
plugins/default.c: Remove chain-ups.
* src/core/window.c: windows which attempt to present themselves
but are offscreen end up demanding attention, unless they
are transient, when they move to the current workspace
as before. Closes#482354.
