This fixes a crash for application set idle inhibitors when their
associated view is being destroyed. There is a call to
`view_is_visible` to determine is the view is visible and it assumes
that the view has an container, but it is possible for the container
to already have been destroyed at this point. There is a NULL check for
the view in `check_active` and this re-adds the NULL check for the
container that I accidentally dropped when refactoring during the
inhibit_idle command PR
This implements the following command to set/unset a user idle
inhibitor for a view:
`inhibit_idle focus|fullscreen|open|none|visible`
The modes are as follows:
- focus: inhibited when the view is focused by any seat
- fullscreen: inhibited when the view is fullscreen (or a descendant of
a fullscreen container) and is visible on any output
- open: inhibited until the view is closed or the inhibitor is unset or
changed
- none: unsets any user set idle inhibitors for the view
- visible: inhibited when the view is visible on any output
This should have no effect on idle inhibitors set by the applications
themselves and those should still work as intended.
Since this operates on the view in the handler context, it is possible
to set it on the currently focused view, on any existing view with
criteria, or for any future view with for_window.
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.
wlr_log_init is still invoked in sway/main.c
This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.
When destroying an idle-inhibiting client, idle_inhibit_v1_check_active can get
called from transaction_progress_queue on a view with a null container.
view_is_visible does not handle a view in this state.
