* Processes daemons
* States of processes:
A description of process states.
It starts in a STOPPED state. On operation "start" or "restart" it gets a pid and goes into RUNNING:
STOPPED --(re)start--> RUNNING
In RUNNING several things can happen:
- It is killed externally: the process then gets a SIGCHLD which triggers a wait and it goes into STOPPED:
RUNNING --sigchld/wait--> STOPPED
It is stopped due to an rpc or by config commit removing the config. In that case the parent
process kills the process and enters into EXITING waiting for a SIGCHLD that triggers a wait:
RUNNING --stop--> EXITING --sigchld/wait--> STOPPED
It is restarted due to an rpc or config change (eg a server is added, a key modified, etc). Then
a new process is started which enters RUNNING, while the old process (the dying clone) enters EXITING:
STOPPED --restart--> RUNNING(newpid)
RUNNING --stop--> EXITING --sigchld/wait--> REMOVED (oldpid/clone)
