func (*Session) GetSessions 

func (s *Session) GetSessions(prefix string) (map[string]*Session, int64, error)

GetSessions will get all sessions registered in etcd. Revision is returned for WatchServices to prevent key events from being missed.

func (*Session) GetSessionsWithVersionRange 

func (s *Session) GetSessionsWithVersionRange(prefix string, r semver.Range) (map[string]*Session, int64, error)

GetSessionsWithVersionRange will get all sessions with provided prefix and version range in etcd. Revision is returned for WatchServices to prevent missing events.

func (*Session) GoingStop 

func (s *Session) GoingStop() error

func (*Session) Init 

func (s *Session) Init(serverName, address string, exclusive bool, triggerKill bool)

Init will initialize base struct of the Session, including ServerName, ServerID, Address, Exclusive. ServerID is obtained in getServerID.

func (*Session) LivenessCheck 

func (s *Session) LivenessCheck(ctx context.Context, callback func())

LivenessCheck performs liveness check with provided context and channel ctx controls the liveness check loop ch is the liveness signal channel, ch is closed only when the session is expired callback must be called before liveness check exit, to close the session's owner component

func (*Session) MarshalJSON 

func (s *Session) MarshalJSON() ([]byte, error)

MarshalJSON marshals session to bytes.

func (*Session) ProcessActiveStandBy 

func (s *Session) ProcessActiveStandBy(activateFunc func() error) error

ProcessActiveStandBy is used by coordinators to do active-standby mechanism. coordinator enabled active-standby will first call Register and then call ProcessActiveStandBy. steps: 1, Enter STANDBY mode 2, Try to register to active key. 3, If 2. return true, this service becomes ACTIVE. Exit STANDBY mode. 4, If 2. return false, which means an ACTIVE service already exist. 

Start watching the active key. Whenever active key disappears, STANDBY node will go backup to 2.

activateFunc is the function to re-active the service.

func (*Session) Register 

func (s *Session) Register()

Register will process keepAliveResponse to keep alive with etcd.

func (*Session) Registered 

func (s *Session) Registered() bool

Registered check if session was registered into etcd.

func (*Session) Revoke 

func (s *Session) Revoke(timeout time.Duration)

Revoke revokes the internal LeaseID for the session key

func (s *Session) Stop()

func (*Session) String 

func (s *Session) String() string

String makes Session struct able to be logged by zap

func (*Session) UnmarshalJSON 

func (s *Session) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshal bytes to Session.

func (*Session) UpdateRegistered 

func (s *Session) UpdateRegistered(b bool)

UpdateRegistered update the state of registered.

func (*Session) WatchServices 

func (s *Session) WatchServices(prefix string, revision int64, rewatch Rewatch) (eventChannel <-chan *SessionEvent)

WatchServices watches the service's up and down in etcd, and sends event to eventChannel. prefix is a parameter to know which service to watch and can be obtained in typeutil.type.go. revision is a etcd reversion to prevent missing key events and can be obtained in GetSessions. If a server up, an event will be add to channel with eventType SessionAddType. If a server down, an event will be add to channel with eventType SessionDelType.

func (*Session) WatchServicesWithVersionRange 

func (s *Session) WatchServicesWithVersionRange(prefix string, r semver.Range, revision int64, rewatch Rewatch) (eventChannel <-chan *SessionEvent)

WatchServicesWithVersionRange watches the service's up and down in etcd, and sends event to event Channel. Acts like WatchServices but with extra version range check. prefix is a parameter to know which service to watch and can be obtained in type util.type.go. revision is a etcd reversion to prevent missing key events and can be obtained in GetSessions. If a server up, an event will be add to channel with eventType SessionAddType. If a server down, an event will be add to channel with eventType SessionDelType.

type SessionEvent 

type SessionEvent struct {
	EventType SessionEventType
	Session   *Session
}

SessionEvent indicates the changes of other servers. if a server is up, EventType is SessAddEvent. if a server is down, EventType is SessDelEvent. Session Saves the changed server's information.

type SessionEventType

	// SessionDelEvent event type for a Session deleted
	SessionDelEvent
	// SessionUpdateEvent event type for a Session stopping
	SessionUpdateEvent
)
