Daemon lifespan truth table
unic multic lifesp behavior
null null <0 no networking, daemon will never end
null null 0 no networking, daemon will NOT be started by this
command
null null >0 no networking, daemon will die after lifespan inactivity
time
null value <0 use multicast to reach daemon, if there is no answer
a new instance will be activated locally; activated
daemon will never end
null value 0 use multicast to reach daemon, if there is no answer
no new instance will be activated locally: an error
will be reported
null value >0 use multicast to reach daemon, if there is no answer
a new instance will be activated locally; activated
daemon will die after lifespan inactivity time
value null <0 use unicast to reach daemon, if there is no answer
a new instance will be started locally, but it can be
activated only if unicast address is a valid address
for the current host; activated daemon will never end
value null 0 use unicast to reach daemon, if there is no answer
no new instance will be activated locally: an error
will be reported
value null >0 use unicast to reach daemon, if there is no answer
a new instance will be started locally, but it can be
activated only if unicast address is a valid address
for the current host; activated daemon will die after
lifespan inactivity time
value value <0 use unicast to reach daemon, if there is no answer
a new instance will be started locally, but it can be
activated only if unicast address is a valid address
for the current host; multicast address will be used
to answer other commands looking for the daemon using
multicast address (null, value, 0); activated daemon
will never end
value value =0 use unicast to reach daemon, if there is no answer
no new instance will be activated locally: an error
will be reported. "multicast" option is ignored, the
same behavior of (value, null, 0)
value value >0 use unicast to reach daemon, if there is no answer
a new instance will be started locally, but it can be
activated only if unicast address is a valid address
for the current host; multicast address will be used
to answer other commands looking for the daemon using
multicast address (null, value, 0); activated daemon
will die after lifespan inactivity time
