Constants

View Source
const DebugModuleName = "control/debug"

DebugModuleName is the module name for the debug controller service.

View Source
const ModuleName = "control"

ModuleName is the module name for the controller service.

Variables

View Source
var ErrIncompatibleBackend = errors.New(DebugModuleName, 1, "debug: incompatible backend")

ErrIncompatibleBackend is the error raised when the current beacon backend does not support manually setting the current epoch.

View Source
var ErrNotImplemented = errors.New(ModuleName, 1, "control: not implemented")

ErrNotImplemented is the error raised when the node does not support the required functionality.

Functions

func RegisterDebugService

func RegisterDebugService(server *grpc.Server, service DebugController)

RegisterDebugService registers a new debug controller service with the given gRPC server.

func RegisterService

func RegisterService(server *grpc.Server, service NodeController)

RegisterService registers a new node controller service with the given gRPC server.

Types

type DebugController

type DebugController interface {
	// SetEpoch manually sets the current epoch to the given epoch.
	//
	// NOTE: This only works with a mock beacon backend and will otherwise
	//       return an error.
	SetEpoch(ctx context.Context, epoch beacon.EpochTime) error

	// WaitNodesRegistered waits for the given number of nodes to register.
	WaitNodesRegistered(ctx context.Context, count int) error
}

DebugController is a debug-only controller useful during tests.

func NewDebugControllerClient

func NewDebugControllerClient(c *grpc.ClientConn) DebugController

NewDebugControllerClient creates a new gRPC debug controller client service.

type DebugStatus added in v0.2201.1

type DebugStatus struct {
	// Enabled is true iff the node is running with DebugDontBlameOasis
	// set.
	Enabled bool `json:"enabled"`

	// AllowRoot is true iff the node is running with DebugAllowRoot
	// set.
	AllowRoot bool `json:"allow_root"`
}

DebugStatus is the current node debug status, listing the various node debug options if enabled.

type IdentityStatus

type IdentityStatus struct {
	// Node is the node identity public key.
	Node signature.PublicKey `json:"node"`

	// Consensus is the consensus public key.
	Consensus signature.PublicKey `json:"consensus"`

	// TLS is the public key used for TLS connections.
	TLS signature.PublicKey `json:"tls"`
}

IdentityStatus is the current node identity status, listing all the public keys that identify this node in different contexts.

type NodeController

type NodeController interface {
	// RequestShutdown requests the node to shut down gracefully.
	//
	// If the wait argument is true then the method will also wait for the
	// shutdown to complete.
	RequestShutdown(ctx context.Context, wait bool) error

	// WaitSync waits for the node to finish syncing.
	WaitSync(ctx context.Context) error

	// IsSynced checks whether the node has finished syncing.
	IsSynced(ctx context.Context) (bool, error)

	// WaitReady waits for the node to accept runtime work.
	WaitReady(ctx context.Context) error

	// IsReady checks whether the node is ready to accept runtime work.
	IsReady(ctx context.Context) (bool, error)

	// UpgradeBinary submits an upgrade descriptor to a running node.
	// The node will wait for the appropriate epoch, then update its binaries
	// and shut down.
	UpgradeBinary(ctx context.Context, descriptor *upgrade.Descriptor) error

	// CancelUpgrade cancels the specific pending upgrade, unless it is already in progress.
	CancelUpgrade(ctx context.Context, descriptor *upgrade.Descriptor) error

	// GetStatus returns the current status overview of the node.
	GetStatus(ctx context.Context) (*Status, error)
}

NodeController is a node controller interface.

func NewNodeControllerClient

func NewNodeControllerClient(c *grpc.ClientConn) NodeController

NewNodeControllerClient creates a new gRPC node controller client service.

type RegistrationStatus

type RegistrationStatus struct {
	// LastAttemptSuccessful is true if the last registration attempt has been
	// successful.

	// LastAttemptErrorMessage contains the error message if the last
	// registration attempt has not been successful.
	LastAttemptErrorMessage string `json:"last_attempt_error_message,omitempty"`

	// LastAttempt is the time of the last registration attempt.
	// In case the node did not successfully register yet, it will be the zero timestamp.
	LastAttempt time.Time `json:"last_attempt"`

	// LastRegistration is the time of the last successful registration with the consensus registry
	// service. In case the node did not successfully register yet, it will be the zero timestamp.
	LastRegistration time.Time `json:"last_registration"`

	// Descriptor is the node descriptor that the node successfully registered with. In case the
	// node did not successfully register yet, it will be nil.
	Descriptor *node.Node `json:"descriptor,omitempty"`
