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.

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.

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.

(cherry picked from commit 9aee47daa984e5cc4a1ccefb3aacfbb2729cfbc1)
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.

The WM_NAME property is of type TEXT_PROPERTY, which is supposed to be
returned as UTF-8. Commit 840378ae68 broke that assumption, resulting
in crashes with non-UTF8 locales; however the "fix" of converting from
LATIN1 to UTF8 is wrong as well, as the conversion will spit out garbage
when the input encoding isn't actually LATIN1.
Now that the original issue in text_property_to_utf8() has been fixed,
we can simply revert the relevant bits of commit d62491f46eba748e.

Commit 840378ae682 changed the code to use XmbTextPropertyToTextList()
instead of gdk_text_property_to_utf8_list_for_display(), but didn't
take into account that the replacement returns text in the current
locale's encoding, while any callers (rightfully) expect UTF8.
Fix this by converting the text if necessary.

Changes in window decoration result in the window being reparented
in and out its frame. This in turn causes unmap/map events, and
XI_FocusOut if the window happened to be focused.
In order to preserve the focused window across the decoration change,
add a flag so that the focus may be restored on MapNotify.

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.

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
Having “on_all_workspaces_requested” FALSE on a window does not imply a
workspace is set.
If the X11 window is placed on a secondary monitor while workspaces
applies on primary monitor only (“workspaces-only-on-primary” set) then
“on_all_workspaces_requested” is FALSE while “on_all_workspaces“ is TRUE
and the associated workspace is NULL, leading to a crash when saving the
gnome-shell/mutter session.
So if no workspace is set, use the “initial_workspace” instead to avoid
a NULL pointer dereference.

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.

Add a new client message "_XWAYLAND_MAY_GRAB_KEYBOARD" that X11 clients
can use to tell mutter this is a well behaving X11 client so it may
grant the keyboard grabs when requested.
An X11 client wishing to be granted Xwayland grabs by gnome-shell/mutter
must send a ClientMessage to the root window with:
- message_type set to "_XWAYLAND_MAY_GRAB_KEYBOARD"
- window set to the xid of the window on which the grab is to be issued
- data.l[0] to a non-zero value
Note: Sending this client message when running a plain native X11
environment would have no effect.

MetaWindowXwayland derives from MetaWindowX11 to allow for some Xwayland

To keep feature parity with the Wayland backend, and

Add a mechanism to MetaWaylandSurface that inhibits compositor's own
shortcuts when the surface has input focus, so that clients can receive
all key events regardless of the compositor own shortcuts.

XWayland clients.

When updating the main monitor, make sure to update the toplevel main
monitor before trying to use that as the main monitor for non-toplevel
windows (such as popups). Without this, when the main monitor is
updated as a side effect to monitors being changed (for example due to
a hot plug event, or coming back from being suspended) the
main monitor pointer may, after 'monitors-changed' has completed, point to
freed memory resulting in undefined behaviour.

Instead of keeping around array indexes, keep track of them by storing
a pointer instead. This also changes from using an array (imitating the

In that case, the MetaWindow is created, but it should also be unminimized

Some applications like Wine may choose to juggle the same user time
window across different toplevels, in that case we receive warnings
when trying to register the window a second time, leading to wrong
accounting.
If the window was already used as the user time window for another
toplevel, unset it from the previous MetaWindow owner, and unregister
so the registration with the new MetaWindow is successful.

In order to kill a window, on both X11 and wayland we first try to
kill(3) the corresponding process, so we can add the newly added
get_client_pid() method to share that code.
https://bugzilla.gnome.org/show_bug.cgi?id=772613
It is often useful to identify the client process that created
a particular window, however the existing meta_window_get_pid()
method relies on _NET_WM_PID, which is only available on X11 and
depends on applications to set it correctly (which may not even
be possible when the app runs in its own PID namespace as Flatpak
apps do). So add a get_client_pid() method that uses windowing
system facilities to resolve the PID associated with a particular
window.

Windows from Xwayland still needs to use the Wayland path, but is
represented an MetaWindowX11, thus the abstraction introduced in
"window: Make meta_window_has_pointer() per protocol implemented"
is wrong. Lets turn back time, and reconsider how this can be
abstracted more correctly in the future.
This reverts commit 9fb891d216478b923f010be23be8790bba6bc7d6.
gjs throws exceptions on non UTF-8 strings which, in some cases, crash
gnome-shell. ICCCM string properties are defined to be Latin-1 encoded
so we can try to convert them to avoid it.
Note that _NET_WM_NAME is defined to be UTF-8 and we already validate
it in utf8_string_from_results() .

To support invoking the system bell on Wayland we shouldn't have paths
that fallback to X11. Let the X11 caller deal with the absence of

This is kind of in a middle ground at the moment. Even though it
handles sequences not coming from libsn, they're added nowhere at
the moment, we'll rely on the app launch context being in the x11
side at the moment.
Also, even though we do create internal sequence objects, we keep
exposing SnStartupSequences to make gnome-shell happy, we could
consider making this object "public" (and the sequence objects with
it), things stay private at the moment.

Some of the mutter code using these properties expects them to be
null-terminated whereas xcb does not use null-terminated strings:
http://xcb.freedesktop.org/XcbRationale/
This was in some cases resulting in the WM_CLASS property containing
garbage data which broke application matching, caused the hot-corner and
window-switcher to stop working, or was exposed as text in the UI.

Some applications, like Chromium, explicitly set their bounding region
to the client area when full-screen. Detect this case, and allow us to
fullscreen when this happens.
When managing a non-OR window we're required by the ICCCM to behave as
if we received a ConfigureRequest which means that we must generate a
synthetic ConfigureNotify even if the window isn't moved or resized
from its current (initial) geometry.
During MetaWindow's x11/wayland split a slight behavior change for x11
windows crept in. Before the code split, MetaWindow->rect was
initialized with the X window's geometry, but now we're not
initializing MetaWindowX11Private->client_rect which causes the checks
for whether it's necessary to move/resize the window in
meta_window_x11_move_resize_internal() to tell us that we do need to
move/resize which means we do an XConfigureWindow() call and don't
send the sythetic ConfigureNotify. But since the X window isn't really
moving, the XConfigureWindow() call doesn't cause the X server to
generate a ConfigureNotify which breaks some clients such as Java's
AWT.
We can fix this by setting MetaWindowX11Privatew->client_rect for both
OR and non-OR windows. We can set buffer_rect for non-OR windows as
well to simplify the code since it will be assigned the correct value
in meta_window_x11_move_resize_internal() .

Wine removes the minimize func from its Motif hints on full-screen
windows, because, as the Win32 API literally says, the minimize button
is indeed not visible on full-screen windows.
Given that this code was added to prevent minimizing a panel by
accident, I don't necessarily think that it's relevant anymore.
