This way, we can simply pop up the Looking Glass and run:
>>> Meta.add_clutter_debug_flags(Clutter.DebugFlag.PICK, 0, 0)
And measure specific actions or events on GNOME Shell.

This function was added for historic reasons, before that we had GSlist's
free_full function.
Since this can be now easily implemented with a function call and an explicit
GDestroyFunc, while no known dependency uses it let's move to use
g_slist_free_func instead.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/57
GList's used in legacy code were free'd using a g_slist_foreach + g_slist_free,
while we can just use g_slist_free_full as per GLib 2.28.
So replace code where we were using this legacy codepath.

Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
If a MetaLater callback queued another MetaLater with a scheduling
later than the one currently being invoked, make it so that the newly
scheduled callback will actually be invoked.
The fact that it doesn't already do this is a regression from
cd7a968093.

Doing this synchronously means that zenity tries to initialize GTK+.
Under Wayland, that will try to connect back to mutter as a display
server. We're waiting on zenity to exit, and zenity is waiting for
a connection response. Deadlock.
Simply assume that zenity will support all the options we feed it,
since it should be the correct version. Perhaps we should replace
our use of zenity with a simple helper binary that we know will
have all the right options if this still isn't good enough.
Warnings that are going to the journal should be not translated:
they're not user visible, and translating them would just make
bug reporting harder (as now the developers need to understand
what the warning is saying)
https://bugzilla.gnome.org/show_bug.cgi?id=707897
Switching meta/util.h to gi18n.h was wrong, mutter is a library
and needs gi18n-lib.h, but that cannot be included from a public
header (since it depends on config.h or command line options),
so split util.h into a public and a private part.
https://bugzilla.gnome.org/show_bug.cgi?id=707897
We want to show a dialog when a display change happens from the
control center. To do so, add a new vfunc to MetaPlugin and
call it when a configuration change is requested via DBus.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
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)
https://bugzilla.gnome.org/show_bug.cgi?id=705670
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.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=649748
During compositor grabs, all global keybindings that don't go
through mutter's keybinding system are blocked. To allow other
processes to make use of it, gnome-shell will expose a simple
grab API on DBus; for this, add API to grab key combos directly
instead of parsing accelerators stored in GSettings.
https://bugzilla.gnome.org/show_bug.cgi?id=643111
Plenty of ugly here, but it works; revert when the zenity version
we depend on stops being bleeding-edge (or we can assume a zenity
version that does not error out on unknown options).

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

This goes better with the general style of similar alerts throughout
GNOME 3, and as has been pointed out in bug 591735, 'Mutter' is
a somewhat unfortunate title in several lanuages, such as English
and German.
* At least one line (possibly blank) is required after a function name for a doc header
to be parsed correctly.
* SnStartupSequence isn't a type known to introspection
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.

Command line arguments are supposed to be in the locale encoding,
not UTF-8, and Zenity decodes command line string command line
arguments with this assumption using GOption.
There was a half-hearted attempt to deal with this in delete.c,
but it wasn't correct since it immediately mixed the window title,
converted to the locale encoding with a UTF-8 message.
https://bugzilla.gnome.org/show_bug.cgi?id=649114
gtk3 no longer has the --screen command-line argument, which mutter
was passing to zenity. Use --display (with an explicitly-specified
screen number) instead.
https://bugzilla.gnome.org/show_bug.cgi?id=643683
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
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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=620359
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.)
When we create the timeline dummy timeline to ensure that our later
functions that should be run during repaint get called called, pass in
G_MAXUINT to make the duration very long, not 0. (It will get reset
whenever there is no repaint later to run, so the fact that G_MAXUINT
is only ~40 days isn't a problem.)
This fixes a warning from Clutter, but also a real problem.
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.
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.
