Types

type Chore

type Chore struct {
	// contains filtered or unexported fields
}

Chore is the contact chore for nodes announcing themselves to their trusted satellites.

architecture: Chore

func NewChore

func NewChore(log *zap.Logger, interval time.Duration, service *Service) *Chore

NewChore creates a new contact chore.

func (*Chore) Close

func (chore *Chore) Close() error

Close stops all the cycles in the contact chore.

func (*Chore) Pause

func (chore *Chore) Pause(ctx context.Context)

Pause stops all the cycles in the contact chore.

func (*Chore) Run

func (chore *Chore) Run(ctx context.Context) (err error)

Run the contact chore on a regular interval with jitter.

func (*Chore) Trigger

func (chore *Chore) Trigger(ctx context.Context)

Trigger ensures that each cycle is done at least once. If the cycle is currently running it waits for the previous to complete and then runs.

func (*Chore) TriggerWait

func (chore *Chore) TriggerWait(ctx context.Context)

TriggerWait ensures that each cycle is done at least once and waits for completion. If the cycle is currently running it waits for the previous to complete and then runs.

type Config

type Config struct {
	ExternalAddress string `user:"true" help:"the public address of the node, useful for nodes behind NAT" default:""`

	// Chore config values
	Interval time.Duration `help:"how frequently the node contact chore should run" releaseDefault:"1h" devDefault:"30s"`
}

Config contains configurable values for contact service.

type Endpoint

type Endpoint struct {
	pb.DRPCContactUnimplementedServer
	// contains filtered or unexported fields
}

Endpoint implements the contact service Endpoints.

architecture: Endpoint

func NewEndpoint

func NewEndpoint(log *zap.Logger, trust *trust.Pool, pingStats *PingStats) *Endpoint

NewEndpoint returns a new contact service endpoint.

func (*Endpoint) PingNode

func (endpoint *Endpoint) PingNode(ctx context.Context, req *pb.ContactPingRequest) (_ *pb.ContactPingResponse, err error)

PingNode provides an easy way to verify a node is online and accepting requests.

type NodeInfo

type NodeInfo struct {
	ID       storj.NodeID
	Address  string
	Version  pb.NodeVersion
	Capacity pb.NodeCapacity
	Operator pb.NodeOperator
}

NodeInfo contains information necessary for introducing storagenode to satellite.

type PingStats

type PingStats struct {
	// contains filtered or unexported fields
}

PingStats contains information regarding when the node was last pinged.

func (*PingStats) WasPinged

func (stats *PingStats) WasPinged(when time.Time)

WasPinged notifies the service it has been remotely pinged.

func (*PingStats) WhenLastPinged

func (stats *PingStats) WhenLastPinged() (when time.Time)

WhenLastPinged returns last time someone pinged this node.

type Service

type Service struct {
	// contains filtered or unexported fields
}

Service is the contact service between storage nodes and satellites.

func NewService

func NewService(log *zap.Logger, dialer rpc.Dialer, self NodeInfo, trust *trust.Pool) *Service

NewService creates a new contact service.

func (*Service) Local

func (service *Service) Local() NodeInfo

Local returns the storagenode info.

func (*Service) PingSatellites

func (service *Service) PingSatellites(ctx context.Context, maxInterval time.Duration) (err error)

PingSatellites attempts to ping all satellites in trusted list until backoff reaches maxInterval.

func (*Service) RequestPingMeQUIC

func (service *Service) RequestPingMeQUIC(ctx context.Context) (err error)

RequestPingMeQUIC sends pings request to satellite for a pingBack via QUIC.

func (*Service) UpdateSelf

func (service *Service) UpdateSelf(capacity *pb.NodeCapacity)

UpdateSelf updates the local node with the capacity.
