ed9d7f18a6 Avoid confusion when _NET_WM_USER_TIME_WINDOW is in the window stack
Wine sets _NET_WM_USER_TIME_WINDOW to point to an unmapped toplevel;
this was causing much confusion because both the real window and
the unmapped window were in the window stack and mapped back to the
same MetaWindow.

97e2b4666b Implement side-by-side tiling
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.

4c0763792d introspection: Build with --warn-fatal, drop fix-meta-rectangle.py hack
Cleanly build with --warn-fatal.  Implementation:

* Liberally apply (skip) where the API is clearly C only, e.g. uses
  XLib.  The theming code and MutterPlugin are skipped too.
* Add missing (transfer) and (element-type) annotations

For a few functions that had a comment, I turned it into gtk-doc, but
I didn't (with a few exceptions) try to write new documentation in
this pass.

e590cd2b99 Don't screw up the event mask when "managing" our own windows
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.

ff5a73de49 Fix problem with window unmaximization
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.

343474a570 Allow logging only specific debug topics
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
of other messages, and it's inconvenient to filter after having
started mutter.

This patch allows one to call Meta.add_debug_topic(Meta.DebugTopic.FOCUS)
from a console, and get just what one wants.

fc9488211f [MetaScreen] Keep num_workspaces key in sync with the actual workspace number
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
number requested by the pager, in which case the pager request becomes a nop.

This commit ensures that when the meta_screen_append_new_workspace() or
meta_screen_remove_workspace() functions are called, the stored value is
updated accordingly.

b77b0a3d81 Load one copy of plugins early
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.)

95b260f3a9 Add meta_prefs_override_preference_location()
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)
as compared to in standalone Metacity.

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.
(we need to know whether to free the old keys or not)

This patch cleans up the comments in prefs.c a bit as well; some ideas
about less-exciting potential improvements were removed to make the
comments explaining the structure easier to figure out.

8fa83e1be7 Fix fallback to builtin defaults for key bindings
The change to reduce GConf trips by using
gconf_client_all_entries() broke the fallback to builtin values
because update_binding() was no longer called for bindings not
found in GConf. Fix this by keeping track of the bindings we
find from GConf in a hash table, then looping through and setting
all the bindings at the end.

This also improves efficiency by avoiding a linear scan for each
binding in GConf.

88ee4c5b30 Don't focus ancestor window on a different workspace
When we are moving a window with a modal dialog to a different
workspace, meta_workspace_focus_default_window() can be called
with 'not_this_one' being the focused modal dialog.

Since the ancestor of that window is also being moved, we must
not focus it as an alternative to the current window; this will
cause windows to be moved back and Metacity to get into an
inconsistent confused state.

ab7d4e0e60 Don't warn about a missing session file
When started without session related command line parameters (e.g. from
gnome-session), metacity picks up client_id from the DESKTOP_AUTOSTART_ID
environment variable. Unfortunately, there is no way to distinguish if this was
passed from a config file, representing old saved session, or generated by
gnome-session, therefore load_state is attempted in each case. If the client_id
is generated, there will be no session file, and metacity will report a
warning.

Just remove the warning so that users won't always find a warning at the

2d57b1b470 Reduce GConf roundtrips
metacity tries to do the right thing, by preloading all the relevant

smart enough to avoid server roundtrips in this case. That should certainly be
fixed in GConf.

In the meantime, here is a patch that reworks the metacity prefs initialization
to avoid roundtrips for individual keys anyway, by using
gconf_client_all_keys().

bacccafe3c Only put demands-attention windows into alt-tab if of appropriate type
Windows demanding attention should never appear in the alt-tab list
unless they're of a type which might have appeared there anyway. This
solves a problem under AWN where docks which were marked as demanding
attention appeared in all alt-tab lists; they were irrelevant and it
was impossible to remove them from the lists.

6ffe5f8343 meta_workspace_set_builtin_struts(): optimize out non-changes
meta_workspace_set_builtin_struts() is slightly expensive; it involves

2a823ef3e4 Fix crash when struts change during grab operation
Since meta_workspace_invalidate_work_area() frees the edges
workspace->screen_edges and workspace->monitor_edges, we must clean up
our cached edge resistance data when the invalidate_work_area() is
called on the active workspace, or when the workspace changes.

Make the computation of the edge resistance data lazy so that it
will be recomputed the next time we try to access it.
meta_display_compute_resistance_and_snapping_edges() is made
private to edge-resistance.c

Invaliding the data when active workspace changes also will improve
correctness for edge resistance when the current workspace changes
during a grab operation. (Even with this fix we still don't try to
handle window positions changing during a grab operation; that can't
cause a crash since, unlike screen and monitor edges, the window edges
are freshly allocated, it will just cause slight oddness in that
corner case.)

Root cause tracked down due to much effort by Jon Nettleton.

576417648a Work around Xlib 64-bit "specialness"
When putting 32-bit properties into longs on 64-bit architectures,
XGetWindowProperty assumes the values are supposed to be signed, and
so it sign-extends values greater than 0x7fffffff. So if they *aren't*
supposed to be signed, we need to chop off the high bits ourselves.

(Most CARDINAL-valued properties only end up using small values
anyway, so it doesn't matter, but _NET_WM_WINDOW_OPACITY uses the full
range, and so was previously failing on 64-bit machines.)

988d2ffab6 Fix handling of SIGCHLD
The commit that removed metacity-dialog added a global SIGCHLD handler
that caused problems by (a) calling waitpid(-1) and thus breaking
g_child_watch for everyone else, and (b) doing too much from a signal
handler and sometimes causing deadlocks (bug 596200).

This removes the global handler and has each zenity user create its
own child watch to watch for exit. (It also fixes the window class of
the zenity dialogs, so that meta_window_present_delete_dialog() will
work again.)

fb45b8f45c Correctly initialize window->input field
With the change from bug 582639, we no longer call the reload
functions for properties that are not initially set, so the
initialization of fields in window.c has to match what
window-props.c would set for a missing property.

There was only one discrepancy, window->input, which needs
to be set to TRUE by default (or a window missing a WM_HINTS
property won't get focus); we also add explicit initializers
for a couple of fields that were getting 0-initialized
to the correct default value of FALSE for consistency with
the explicit intialization of the rest of the fields.

e8a29c1e82 Work around race condition focusing a window on a different workspace
When we focus a window on a different desktop, and the calc_showing
idle that hides/shows the windows gets run before we get focus events
back from X, we think that we are hiding the window with the focus
so we focus a "random" window to avoid leaving the user with no focus.

Work around this temporarily by checking display->expected_focus_window;
this isn't a perfect fix because there are cases where
display->expected_focus_window corresponds to a window we tried to
focus in the past but failed, but it makes things work fairly well.

3508c4aa87 Use "later functions" to fix priority problems with Clutter redraw
There was a problem where if, for example, a restack was triggered
out of a clutter event handler, then after Clutter processed the
events, it would proceed immmediately on to repaint the stage without
ever returning control to the GLib main loop. So even though we
had an idle handler installed with a higher priority than the
Clutter stage repainting the clutter stage repainting would happen
first and we'd get a wrong frame.

Fix this by introducing the idea of "later functions", which abstract
the idea of "doing something later" away from g_idle_add() and use
a combination of GLib idle functions and Clutter "repaint functions"
to get our callbacks triggered at the right time, even when they
are installed from a clutter event handler.

https://bugzilla.gnome.org/show_bug.cgi?id=596334

This also resolve a FIXME where MUTTER_PRIORITY_BEFORE_REDRAW
could starve stage repainting.

custom-alt-tab keypress handlers, since that code was assuming that

process_event() and then to the plugin's xevent_filter to detect a
key release.

We centeralize all of this handling into process_tab_grab() and either

 - Invoke a custom handler for the key press
 - Select the current window on modifier release by calling a  new
   pseudo-binding "tab_popup_select"
 - Cancel the grab on an unbound key by calling a new pseudo-binding

will have NET_WM_WINDOW_TYPE_NORMAL set on them because of shared

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

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.)

9244f0f113 Move window repair and reshape to a paint function
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.

bc9a2cc92a Don't move hidden windows to the desktop layer
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.

2c17ef4803 Emit signals when workspaces are added, removed or switched
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.

3aff9726eb Remove MetaCompositor virtualization
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.

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.

  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.

6314ee8780 Move compositor-stack handling to MetaStackTracker
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.

a4cd66f599 Add better tracking of real stacking order
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
  stacking order or add windows, record those changes immediatley
  in MetaStackTracker so we have the information without waiting
  for a round-trip.

include/ui.h ui/ui.c: meta_ui_create_frame_window add a return value
  for the X request serial used to create the window.

- Don't queue a resize on override-redirect windows when reading

fd27647440 Don't read most properties for override-redirect windows
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.
