Mutter is a Clutter-based compositing manager. So, remove the code for
the XRender-based compositor, and make it mandatory to have XComposite,
XRender and Clutter.
Run-time support for non-composited operation is left for now.
* src/compositor/mutter/: Move files from this subdirectory into
the main compositor/ directory.
* compositor/compositor-xrender.ccompositor/compositor-xrender.h:
Remove
* include/compositor-clutter.h: Remove this stray file, it had been
replaced with compositor-mutter.h some time back.

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.

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.
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.
Change #define _XOPEN_SOURCE 500 to 600 in compositor-xrender.c to
avoid a bad interaction with -xc99 on Solaris.
Remove unneeded #define in compositor-mutter.c.

Cogl's default blend function has been switched to expect premultiplied
alpha. Change the combine function and the colors we use to
modulate alpha to match.

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.
http://bugzilla.gnome.org/show_bug.cgi?id=585151
- Use float instead of ClutterUnit
- clutter_actor_get_size/position() return floats (remove some
stray usage of these functions in the default plugin as well.)
- Adapt to cogl_texture_new_from_data() changes
- Use blend strings to set up multitexturing
- Remove CLUTTER_UNITS_TO_FLOAT() usage

If the input region has been shaped, then clutter needs to
receive EnterNotify/LeaveNotify events in order to properly
send enter and leave events to actors when the pointer crosses
the boundary of the stage.

If mutter_plugin_set_stage_input_region() and related methods are
called before the output window is available, save the set input
region and apply it to the output window later on.
compository-mutter.[ch]: Add mutter_set_stage_input_region() and
mutter_empty_stage_input_region(), move the input region handling
here and implement the delayed shape setting described
above.
mutter-plugin.c: Implement shape setting in terms of the new methods.

Using G_MODULE_BIND_LOCAL causes problems for introspecting plugins,
since introspected symbols need to be globally available. And in
any case, trying to use linker features to prevent symbol conflicts
doesn't usually work out very well, it's better to just namespace
properly.
http://bugzilla.gnome.org/show_bug.cgi?id=580033
Add separate mutter_plugin_manager_load() and
mutter_plugin_manager_initialize() calls so that we can just
load the plugins without start them. This is useful for introspecting
a gnome-shell plugin at build time.
http://bugzilla.gnome.org/show_bug.cgi?id=580032
To guard against CompositeNameWindowPixmap failing, just use an
error trap. Previous code used:
GrabServer/GetWindowAttributes/CompositeNameWindowPixmap/UngrabServer
To prevent BadMatch errors from !viewable, but didn't check the
return value of GetWindowAttributes and didn't check if an error
occured during the error trap. This way is more correct and more
efficient.
http://bugzilla.gnome.org/show_bug.cgi?id=580023
The overlay window was created before the plugins are loaded. Because the
composite extension immediately maps the window, we ended blanking the screen
while plugins, etc., were loading. This commit reorganizes the code so that
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.
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.
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.
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.
Fix a problem where GTK+ was warning
'gdk_window_set_user_time called on non-toplevel' for every button
press and click on the mutter stage by excluding such events from
GTK+ processing.
Add a boolean return value to meta_compositor_process_event that
indicates whether the event has been handled and should be filtered
out of the event stream and for mutter, base that on the return
value of the plugin's xevent_filter vfunc.
Before we've retrieved a pixmap for a window, the shaped texture
has a 0x0 texture, which will cause mutter_shaped_texture_ensure_mask()
to crash. Just skip all of paint/pick in this case.
http://bugzilla.openedhand.com/show_bug.cgi?id=1283
Add (transfer none) annotations to mutter_window_get_texture()
and mutter_window_get_meta_window(), and while add doc comments,
actually add some docs as well.
Since this is the most common cause of performance issues, this makes it
clearer when GLX TFP isn't being used. Note, there was a corresponding
fix to clutter_glx_texture_pixmap_using_extension() committed last week
as r3559 in the 0.8 branch.

The metacity core is now directly aware of override redirect windows.
- They get MetaWindows like normal windows, so mutter no longer need to special
case them. The net wm types applicable to override redirects are also
recognised.
- The original positioning/stacking semantics of metacity with respect to OR
windows are maintained, but now it's easier to synchronize the stacking
between the core and mutter.
- mutter no longer needs to manualy track UnmapNotify, MapNotify,
ReparentNotify, CreateNotify and DestroyNotify events; instead map, unmap,
add and remove events can now be consistently delivered via the
MetaCompositor callbacks.
Make MetaWindow into a GObject so that it is accessible to
gobject-introspection (also allows for signals to be added.)
Renames:
meta_window_free() => meta_window_unmanage()
meta_window_get_type() => meta_window_get_window_type()
meta_window_get_type_atom() => meta_window_get_window_type_atom()
It's more awkward and error prone, considering plugin ininteractions, to simply
show/hide the actors of hidden windows, and it seems to be more reliable to
reparent them to a hidden group instead.
We can't easily use a metacity layer to hide windows as that means we
loose our original stacking position. (Metacity's stack positions are
only valid within a single layer) We now have a "guard window" per
screen that is a fullscreen override redirect that is lowered to the
bottom of the stack. Hidden windows now remain in their original layer
so the stacking position remains valid, but all hidden windows get
XRestacked under the guard window.
A new compositor hook is also added to inform it when a window becomes
hidden/unhidded, this lets us map/unmap the corresponding actor.
missing files in preview commit (TODO: rebase -i and squash this later)
Calling clutter_actor_show_all() on the stage and overlay_group breaks
the ability for plugins to create initially hidden actors. Call
clutter_actor_show() instead.
If a mutter plugin name (in GConf, or more likely on the command line)
looks like an absolute path, use that path directly rather than
looking for the plugin in the plugins directory.
Remove a "got here" leftover, remove unnecessary trailing \n when
calling g_message(), include g_module_error() in the output when
loading a module fails.
If --disable-static is passed to configure, then .a files won't be built
or installed. Make removing them in install-exec-hook not fatal if they
don't exist.
We need to be getting ConfigureNotify events for these, so we can respond
to changes in position of these windows. We cannot add this to windows
Metacity manages, as this makes it got mental.
ClutterActors for hidden windows (such windows on different than active
workspaces and windows that are minimized) are available, and reflect the
actual state of the window. This is intended for use in task-switchers etc.
This feature is disabled by default (due to increased demand on resources),
and can be enabled through the metacity/general/live_hidden_windows gconf key.
A trivial sample window switcher is included in the scratch plugin (activated
by clicking on the slide out panel).
terse variable names, simplify the plugin interface or consider tweaks
for maintainability.
* Renames plg -> plugin
* Renames mgr ->plugin_mgr (since in a combined window and composite
manager I think "mgr" will end up being ambiguous in places)
* Renames PluginWorkspaceRectangle -> MetaRectangle (We are no longer
concerned about mbwm2 portability)
* Renames a few one letter variable names e.g. a -> window, r ->rect
* Renames some vars to indicate what they represent not their data type,
e.g. group1, group2 ->workspace0, workspace1
* Renames the variable mcw -> mc_window to make it more immediately
obvious what it represents.
* Removes the verbose META_COMPOSITOR_CLUTTER_PLUGIN_SWITCH_WORKSPACE macro,
and just uses metacity_plugin instead.
* Instead of hanging data of the plugins global descriptor, we just use a
standalone static global variable.
* Make do_init a function pointer inside the plugin descriptors instead of
special casing it and using another g_module_symbol call. This also removes
the need for the META_COMPOSITOR_CLUTTER_PLUGIN_INIT_FUNC macro.
* A bunch of anal 80char fixes
* Removes the screen_width,height variables from the plugin descriptor struct
and add a plugin API instead.
The actor's private data created by the compositor is allocated
using g_new(), but since we are allocating a lot of small structures
all the time it's better to use the slice allocator instead.
Also, use a GQuark instead of using a string, so that the quark
lookup is done only once and the rest of the time is just an
integer comparison.
Renamed meta_compositor_clutter_plugin_manager_event_0 to
meta_compositor_clutter_plugin_manager_event_simple and
meta_compositor_clutter_plugin_manager_event_4i to
meta_compositor_clutter_plugin_manager_event_maximize for improved clarity.
Check for whether clutter/glx/clutter-glx-texture-pixmap.h is
available in the configure script and if not use
ClutterX11TexturePixmap directly.
glGetTexLevelParameter isn't available on GL ES so instead it checks
whether NPOTs textures are available and assumes the next power of two
size if not.
So we do not have to query window attributes in the MetaCompWindow constructor
but can pass them as a property (so we can gracefully handle the case where no
attributes can be retrieved).
Fixed up the build files so we do not build xrender compositor when building
clutter backend; moved clutter initialization to meta_ui_init() so commandline
arguments can be passed into clutter_init().
No Expose event processing is necessary, since clutter stage paints
automatically when changes are made to the scenegraph (so we only need to
update our window textures as damaged; everything else just works).
