Followup on 4e4898e90f.
If a view quickly maps and unmaps repeatedly, there will be multiple
destroyed containers with same view in a single transaction. Each of
these containers will then try to destroy this view, resulting in use
after free.
The container should only destroy the view if the view still belongs
to the container.
Simple reproducer: couple XMapWindow + XUnmapWindow in a loop followed
by XDestroyWindow.
See #6605
cairo_image_surface_create can fail, e.g. when running out of
memory or when the size is too big. Avoid crashing in this case.

Now output_begin_destroy emits the node::destroy event similar to
workspace_begin_destroy. It currently has no listeners, since they
listen to output::disable or wlr_output::destroy instead.
Add a subcommand for `smart_gaps` that enables outer gaps only
on workspaces with exactly one visible child.
Also add documentation for `smart_gaps toggle`.
If the focused container is floating by itself, create a new container
in tiling mode as a sibling of the inactive focused container instead of
creating it as a sibling of everything that is in tiling mode in that
workspace. This is the i3 behavior.
Prior to 62d90a8e, titlebar's font height (and other related values)
would change any time any titlebar's content changed, so these values
were recalculated each time any titlebar's content changed (or a new
titlebar was created).
However, since the above was merge, these values no longer change so
often and we only need to recalculate them when the configured font
changes (and stop calling `config_update_font_height` each time
titlebars are rendered).
This commit removes all the unecessary calls to this function and avoids
all those unecessary calculations. Whenever the font strays from the
default value, the `font` command is called, and it calls
`config_update_font_height`, which is enough to keep the value always up
to date.
I've also added a default value to the `font_baseline` config, since
otherwise that's zero for setups that don't explicitly specify a font.
The title itself and marks were being rendered by two very-similar yet
different functions, and any changes made to one had to be reflected on
the other.
This mostly prevents such oversights from happening, and keeps makes
sure we keep both consistent.
Use fixed titlebar heights. The default height is calculated based on
font metrics for the configured font and current locale.
Some testing with titles with emoji and CJK characters (which are
substantially higher in my setup) shows that the titlebars retain their
initial value, text does shift up or down, and all titlebars always
remain aligned.
Also drop some also now-unecessary title_height calculations.
Makes also needed to be updated, since they should be positioned with
the same rules.
The xdg-decoration protocol allows clients to request whether they want
to use server side decorations or client side decorations. Currently,
sway ignores this and always enforces whatever the server is currently
set to. Although tiled clients cannot be allowed to set borders, there
is no harm in listening requests from floating clients. Sidenote: also
fix an unrelated style error.
When setting the geometry from content for floating windows, the
coordinates for borders are normally taken into account. However in the
case of a floating fullscreen window, we should not be doing this. Since
the content of the container takes the space of the entire output, this
causes the calculated borders to neccesarily be outside of the output.
This later causes a problem when sending surface entrance events since
in a multi-monitor setup, the border coordinates will overlap with
another output despite the surface not actually being on that output at
all. The fix is to just ignore border coordinates for a floating
fullscreen container since fullscreen, of course, does not actually have
any borders. Fixes#6080.
This fixes the following scenario:
- Place a floating window so its border is right at the edge of the
screen
- Create a new split
- The border disappears
- Moving the window does not restore the border
Instead of disabling it for some workspace subcommands, this explicitly
calls it only in the 2 places it's actually needed: for switching to a
named or numbered workspace.
This extracts the code to a separate workspace_auto_back_and_forth
function.
It also removes the bool argument by adding an extra if statement at the call
site, and repurposes the no_auto_back_and_forth variable to
auto_back_and_forth for simpler understanding.
remove view from its own unmap event listener so when subsurfaces
link try to remove themselves they won't run into it.
This fixes the following ASAN use-after-free error on a build slightly

Fixes#5168
the original behavior set fullscreen for all descendents of a container,
which causes issues when firefox is one of those children because it
sends its own set_fullscreen request in response to being fullscreened.
When a tiling container is floated, the focus stack needs to be
appropraitely modified to return the container to its original
position in the tree upon floating disable, like i3.
container_at checks if the position provided matches the currently
focused container with view_container_at as a fast path.
view_container_at checks using the main container geometry, which
includes the titlebar and border area. If a tabbed container is focused,
then positions over unfocused tabs are incorrectly reported as belonging
to the focused container, breaking focus on click.
Add view_container_content_at for use in the focused container fast path
which only tests container content area, and fall back to full workspace
scans for border and titlebar areas.
Closes: https://github.com/swaywm/sway/issues/6074
container_at would maintain the current focus as long as a position was
over one of the container view's surfaces. If an oversized surface was
being clipped, this lead to weird focus behavior.
Instead, use view_container_at for this test, which intersects the
container box before looking at surfaces.
When issuing a focus command on a specific container, users expect to
proceed it even if is hidden by a fullscreen window.
This matches the behavior of i3.
view_child_init was calling view_init_subsurfaces, which did not set the
parent attribute for the subchildren. This lead to the subchildren
acting as standalone children. If the parent was an xdg_popup, this
would make the subchild unaware of the popup position.
Introduce view_child_init_subsurfaces for view_child_init to use
instead.
Closes: https://github.com/swaywm/sway/issues/6038
The subchildren lose their parent association at this point, so they
will not be able to see that the parent is unmapped.
Instead, just set the subchildren to be unmapped directly.
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.
Instead, use the state struct for both current and pending.
