Sway sets a default status_command which runs date every second. This
patch removes this behaviour so the user can have a NULL status bar if
desired.
I had to swap swaybar's event_loop_poll and wl_display_flush so that it
would map the initial surface.
This patch makes it so when you run reload, the actual reloading is
deferred to the next time the event loop becomes idle. This avoids
several use-after-frees and removes the workarounds we have to avoid
them.
When you run reload, we validate the config before creating the idle
event. This is so the reload command will still return an error if there
are validation errors. To allow this, load_main_config has been adjusted
so it doesn't apply the config if validating is true rather than
applying it unconditionally.
This also fixes a memory leak in the reload command where if the config
failed to load, the bar_ids list would not be freed.
When destroying swaynag from within wl_display_dispatch, we cannot
disconnect the display as that will free the queue's event_list.
Free it after running the loop instead.
Fixes this use-after-free:

(you need a wayland compiled with asan, my wl_list hack, or running
with valgrind to see this trace)
Today I learned that GNU flaunts the POSIX standard in yet another
creative way. Additionally, this adds some security improvements,
namely:
- Zeroing out password buffers in the privileged child process
- setuid/setgid after reading /etc/shadow
* Create a view on workspace 1
* Switch to workspace 2 (on the same output) and create a floating
sticky view
* Use criteria to focus the view on workspace 1
Previously, we only moved the sticky containers when using
workspace_switch, but the above method of focusing doesn't call it. This
patch relocates the sticky-moving code into seat_set_focus_warp.
A side effect of this patch is that if you have a sticky container
focused and then switch workspaces, the sticky container will no longer
be focused. It would previously retain focus.
In seat_set_focus_warp, new_output_last_ws was only set when changing
outputs, but now it's always set. This means new_output_last_ws and
last_workspace might point to the same workspace, which means we have to
make sure we don't destroy it twice. It now checks to make sure they're
different, and to make this more obvious I've moved both calls to
workspace_consider_destroy to be next to each other.
container_flatten removes the container from the tree (via
container_replace) before destroying it. When destroying, the recent
changes to handle_seat_node_destroy incorrectly assumes that the
container has a parent.
This adds a check for destroying a container which is no longer in the
tree. If this is the case, focus does not need to be changed.
* Click and hold a scrollbar
* Drag the cursor onto another surface
* While still holding the original button, press and release another
cursor button
* Things get weird
There's two ways to fix this. Either cancel the seat operation and do
the other click, or continue the seat operation and ignore the other
click. I opted for the latter (ignoring the click) because it's easier
to implement, and I suspect a second click during a seat operation is
probably unintentional anyway.
* Have multiple outputs
* Launch swaylock
* Unplug an output (possibly has to be the last "connected" one)
* The swaylock surface on the remaining output would not respond to key
events
This was happening because when the output destroys, focus was not given
to the other swaylock surface.
This patch makes focus be transferred to another surface owned by the
same Wayland client, but only if input was inhibited by the surface
being destroyed, and only if it's in the overlay layer. I figure it's
best to be overly specific and relax the requirements later if needed.
This patch removes a check in seat_set_focus_surface which was
preventing focus from being passed from a layer surface to any other
surface. I don't know of a use case for this check, but it's possible
that this change could produce issues.
Re-focus on the container on which the cursor hovers over. A
special case is, if there are menus or other subsurfaces open
in the focused container. It will prefer the focused container
as long as there are subsurfaces.
This commit starts caching the previous node as well as the
previous x/y cursor position. Re-calculating the previous
focused node by looking at the current state of the cursor
position does not work, if the environment changes.
* New configuration option: raise_floating
(From the discussion on https://github.com/i3/i3/issues/2990)
* By default, it still raises the window on focus, otherwise it
will raise the window on click.
To reproduce the problem, create layout
H[view V[view view view-focused]], then switch to another workspace and
have the previously focused view in the vsplit close (eg. using
criteria, or an mpv video finishing). Return to the workspace using
`$mod+<num>` and the entire vsplit would be focused. This happens
because handle_seat_node_destroy would only set a new focus if the
currently focused view or a parent was being destroyed. To fix it, it
needs to set a sibling of the destroying container to focus_inactive
regardless of the current focus, then restore current focus if needed.
This patch changes the function accordingly. Additionally:
* The function now makes an early return if the node being destroyed is
a workspace.
* set_focus has been renamed to needs_new_focus. This variable is true
if the head focus needs to be changed.
