Instead of storing the result of meta_prop_get_latin1_string() into
a temporary string value, g_strdup-ing that temp value storing the
g_strdup result into window->sm_client_id and then g_free-ing the
temporary string, we can pass window->sm_client_id as the place where
meta_prop_get_latin1_string() stores its result, since the result
from meta_prop_get_latin1_string() is itself a g_strdup-ed string,
so there is no need to g_strdup it again.
Note this drops the check to only issue the
"Window %s sets SM_CLIENT_ID on itself ..." warning once. This check is
not necessary as update_sm_hints() is only called once at window
creation time and is never called again.

latin1_string_from_results and utf8_string_from_results use g_strndup,
so the returned string should be freed with g_free, rather then with
free or XFree. This fixes all free-s of buffers returned by these 2
functions to properly use g_free.

Starting with commit 2db94e2e we try to focus a fallback default focus window
if no take-focus window candidate gets the input focus when we request it and
we limit the focus candidates to the current window's workspace.
However, if the window is unmanaging, the workspace might be unset, and we could
end up in deferencing a NULL pointer causing a crash.
So, in case the window's workspace is unset, just use the currently active
workspace for the display.
Closes https://gitlab.gnome.org/GNOME/mutter/issues/687https://gitlab.gnome.org/GNOME/mutter/merge_requests/688
As per commit f71151a5 we focus an input window if no take-focus-window accepts
it. This might lead to an infinite loop if there are various focusable but
non-input windows in the stack.
When the current focus window is unmanaging and we're trying to focus a
WM_TAKE_FOCUS window, we intent to give the focus to the first focusable input
window in the stack.
However, if an application (such as the Java ones) only uses non-input
WM_TAKE_FOCUS windows, are not requesting these ones to get the focus. This
might lead to a state where no window is focused, or a wrong one is.
So, instead of only focus the first eventually input window available, try to
request to all the take-focus windows that are in the stack between the
destroyed one and the first input one to acquire the input focus.
Use a queue to keep track of those windows, that is passed around stealing
ownership, while we protect for unmanaged queued windows.
Also, reduce the default timeout value, as the previous one might lead to an
excessive long wait.
Added metatests verifying these situations.

As per commit f71151a5 we were ignoring WM_TAKE_FOCUS-only windows as focus
targets, however this might end-up in an infinite loop if there are multiple
non-input windows stacked.
So, accept any focusable window as fallback focus target even if it's a
take-focus one (that might not reply to the request).
Added a stacking test to verify this.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/660https://gitlab.gnome.org/GNOME/mutter/merge_requests/669
When looking for the best fallback focus window, we ignore it if it is in the
unmanaging state, but meta_stack_get_default_focus_window() does this is check
for us already.
So, ignore the redundant test.

When requesting to a take-focus window to acquire the input, the client may or
may not respond with a SetInputFocus (this doesn't happen for no-input gtk
windows in fact [to be fixed there too]), in such case we were unsetting the
focus while waiting the reply.
In case the client won't respond, we wait for a small delay (set to 250 ms) for
the take-focus window to grab the input focus before setting it to the default
window.
Added a test for this behavior and for the case in which a window takes the
focus meanwhile we're waiting to focus the default window.

In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/420
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.

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.

It's a UI pattern that has been superseded by client-side decorations,
apps that used to set the hint have generally moved on to headerbars.
Given that and the limitation to server-side decorated X11 windows,
GTK4 removed the client-side API for setting the hint, it's time to
follow suite and retire the feature.

It relied on indices in arrays determining tile direction and
non-obvious bitmask logic to translate to _GTK_EDGE_CONSTRAINTS. Change
this to explicitly named edge constraints, and clear translation methods
that converts between mutters and GTK+s edge constraint formats.
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.
The bool determines whether the call was directly from a user operation
or not. To add more state into the call without having to add more
boolenas, change the boolean to a flag (so far with 'none' and 'user-op'
as possible values). No functional changes were made.

This moves following objects from MetaScreen to MetaDisplay

Split X11 specific parts into MetaX11Display. This also required
changing MetaScreen to stop listening to any signals by itself, but
instead relying on MetaDisplay forwarding them. This was to ensure the
ordering. MetaDisplay listens to both the internal and external
monitors-changed signal so that it can pass the external one via the
redundant MetaDisplay(prev MetaScreen)::monitors-changed.

They are X11 specific functions, used for X11 code. They have been
improved per jadahl's suggestion to use gdk_x11_lookup_xdisplay and
gdk_x11_display_error_trap_* functions, instead of current code.

In the old, synchronous X.org world, we could assume that
a state change always meant a synchronizing the window
geometry right after. After firing an operation that
would change the window state, such as maximizing or
tiling the window,
With Wayland, however, this is not valid anymore, since
Wayland is asynchronous. In this scenario, we call
meta_window_move_resize_internal() twice: when the user
executes an state-changing operation, and when the server
ACKs this operation. This breaks the previous assumptions,
and as a consequence, it breaks the GNOME Shell animations
in Wayland.
The solution is giving the MetaWindow control over the time
when the window geometry is synchronized with the compositor.
That is done by introducing a new result flag. Wayland asks
for a compositor sync after receiving an ACK from the server,
while X11 asks for it right away.
Fixes#78
mutter would discard the shape region set by the client if its matches
the entire client area in meta_window_x11_update_shape_region().
However, if the window is later resized (maximized or other), the
compositor will fail to update the shape region properly for undecorated
windows because the shape region was discarded, which causes black areas
to appear in place of the updated areas.
If the client window is undecorated, keep the shape region even if when
it matches the client area.

When a window's workspace is not NULL, on_all_workspace should be FALSE.
Similarly, when on_all_workspace is TRUE, the window workspace should be
NULL.
This is an assumption in multiple places in the code, including when
setting the workspace state, the window is either added or removed from
all workspaces only if the window's workspace is NULL.
This rule is initially enforced at creation in _meta_window_shared_new()
when a initial workspace is set. However, when the initial workspace is
set from the session info, the initial workspace is not marked as “set”
which leads to an assertion failure when unmanaging windows, because the
window is not removed from all the workspaces.
When applying the session info to a window, mark the workspace as “set”.
https://gitlab.gnome.org/GNOME/mutter/issues/4Closes: #4
When closing a window and showing a new one, the new one may not be
granted input focus until it gets a buffer on Wayland.
If another window is chosen to receive focus and raised on top of stack,
the newly mapped window is focused but placed underneath that other
window.
Meaning that for Wayland surfaces, we need to defer adding the window to
the stack until we actually get to show it, once we have a buffer
attached.
Rather that checking the windowing backend prior to decide if a window
is stackable or not, introduce a new vfunc is_stackable() which tells
if a window should be added to the stack regardless of the underlying
windowing system.
Also add meta_window_is_in_stack() API rather than checking the stack
position directly (replacing the define WINDOW_IN_STACK only available
in stack.c) and remove a window from the stack only if it is present
in the stack, so that the test in meta_stack_remote() becomes
irrelevant.

MetaWindowXwayland derives from MetaWindowX11 to allow for some Xwayland
specific vfunc that wouldn't apply to plain X11 windows, such as
shortcut inhibit routines.

To keep feature parity with the Wayland backend, and
to improve the overall tiling experience with GTK apps,
add the _GTK_EDGE_CONSTRAINTS X11 atom and update it
when necessary.
