Node is the Oasis node service.

WARNING: This is exposed for the benefit of tests and the interface is not guaranteed to be stable.

func NewNode

func NewNode() (node *Node, err error)

NewNode initializes and launches the Oasis node service.

WARNING: This will misbehave iff cmd != RootCommand(). This is exposed for the benefit of tests and the interface is not guaranteed to be stable.

Note: the reason for having the named err return value here is for the deferred func below to propagate the error.

func (*Node) Cleanup

func (n *Node) Cleanup()

Cleanup cleans up after the node has terminated.

func (*Node) GetIdentity

func (n *Node) GetIdentity() *identity.Identity

Implements control.ControlledNode.

func (*Node) GetPendingUpgrades

func (n *Node) GetPendingUpgrades(ctx context.Context) ([]*upgrade.PendingUpgrade, error)

Implements control.ControlledNode.

func (*Node) GetRegistrationStatus

func (n *Node) GetRegistrationStatus(ctx context.Context) (*control.RegistrationStatus, error)

Implements control.ControlledNode.

func (*Node) GetRuntimeStatus

func (n *Node) GetRuntimeStatus(ctx context.Context) (map[common.Namespace]control.RuntimeStatus, error)

Implements control.ControlledNode.

func (*Node) Ready

func (n *Node) Ready() <-chan struct{}

Implements control.ControlledNode.

func (*Node) RegistrationStopped

func (n *Node) RegistrationStopped()

Implements registration.Delegate.

func (*Node) RequestShutdown

func (n *Node) RequestShutdown() (<-chan struct{}, error)

Implements control.ControlledNode.

func (*Node) Stop

func (n *Node) Stop()

Stop gracefully terminates the node.

func (*Node) Wait

func (n *Node) Wait()

Wait waits for the node to gracefully terminate. Callers MUST call Cleanup() after wait returns.
