17 * This header defines ServiceRecord, a data record maintaining information about a service,
18 * and ServiceSet, a set of interdependent service records. It also defines some associated
19 * types and exceptions.
23 * Services have both a current state and a desired state. The desired state can be
24 * either STARTED or STOPPED. The current state can also be STARTING or STOPPING.
25 * A service can be "pinned" in either the STARTED or STOPPED states to prevent it
26 * from leaving that state until it is unpinned.
28 * The total state is a combination of the two, current and desired:
29 * STOPPED/STOPPED : stopped and will remain stopped
30 * STOPPED/STARTED : stopped (pinned), must be unpinned to start
31 * STARTING/STARTED : starting, but not yet started. Dependencies may also be starting.
32 * STARTING/STOPPED : as above, but the service will be stopped again as soon as it has
34 * STARTED/STARTED : running and will continue running.
35 * STARTED/STOPPED : started (pinned), must be unpinned to stop
36 * STOPPING/STOPPED : stopping and will stop. Dependents may be stopping.
37 * STOPPING/STARTED : as above, but the service will be re-started again once it stops.
39 * A scripted service is in the STARTING/STOPPING states during the script execution.
40 * A process service is in the STOPPING state when it has been signalled to stop, and is
41 * in the STARTING state when waiting for dependencies to start or for the exec() call in
42 * the forked child to complete and return a status.
44 * Acquisition/release:
46 * Each service has a dependent-count ("required_by"). This starts at 0, adds 1 if the
47 * service has explicitly been started (i.e. "start_explicit" is true), and adds 1 for
48 * each dependent service which is not STOPPED (including dependents with a soft dependency).
49 * When required_by transitions to 0, the service is stopped (unless it is pinned). When
50 * require_by transitions from 0, the service is started (unless pinned).
52 * So, in general, the dependent-count determines the desired state (STARTED if the count
53 * is greater than 0, otherwise STOPPED). However, a service can be issued a stop-and-take
54 * down order (via `stop(true)'); this will first stop dependent services, which may restart
55 * and cancel the stop of the former service. Finally, a service can be force-stopped, which
56 * means that its stop process cannot be cancelled (though it may still be put in a desired
57 * state of STARTED, meaning it will start immediately upon stopping).
61 * A service may be "pinned" in either STARTED or STOPPED states (or even both). Once it
62 * reaches a pinned state, a service will not leave that state, though its desired state
63 * may still be set. (Note that pinning prevents, but never causes, state transition).
65 * The priority of the different state deciders is:
68 * - desired state (which is manipulated by require/release operations)
70 * So a forced stop cannot occur until the service is not pinned started, for instance.
72 * Two-phase transition
73 * --------------------
74 * Transition between states occurs in two phases: propagation and execution. In the
75 * propagation phase, acquisition/release messages are processed, and desired state may be
76 * altered accordingly. Desired state of dependencies/dependents should not be examined in
77 * this phase, since it may change during the phase (i.e. its current value at any point
78 * may not reflect the true final value).
80 * In the execution phase, actions are taken to achieve the desired state. Actual state may
81 * transition according to the current and desired states.
