sx doesn't kill while loops

[handow23]

sx doesn't kill while loops inside sxrc or external scripts.

example:

# Statusbar loop
while true; do
   xsetroot -name "$( date +"%F %R" )"
   sleep 1m    # Update time every minute
done &

when I exit my WM (dwm) xsetroot says it can't open display 1 every minute. this issue doesn't happen on xinit.

This would be the responsibility of your script.

Any background processes when the parent exits, unless it is cleaned up, will be orphaned and reaped by PID 1 (or a subreaper).

You could fix this by installing a trap handler which kills the entire process group upon exiting, e.g.:

trap 'kill 0' EXIT

[handow23]

where should I put the handler? moreover, dbus is complaining about being unable to spawn a command:

Error connecting: Error spawning command line “dbus-launch --autolaunch=616ef277b96d7a69d1faa96a5f567df0 --binary-syntax --close-stderr”: Child process exited with code 1

Autolaunch error: X11 initialization failed.

The trap would be placed in your sxrc (as with any process sx starts (see bernstein chains)).

The dbus issues are unrelated and likely occur due to the lack of a DBUS_SESSION_BUS_ADDRESS environment. However as dbus-launch is deprecated, could you try dbus-run-session instead?
If you need to set the environment it usually takes the form of DBUS_SESSION_BUS_ADDRESS=unix:path=$XDG_RUNTIME_DIR/bus but this may differ on runit based inits.
