Functions

func From added in v0.3.0 

func From(typ interface{}) interface{}

From(*T) -> func(t T) T {return t}

func FullNodeHandler added in v1.11.0 

func FullNodeHandler(a v1api.FullNode, permissioned bool, opts ...jsonrpc.ServerOption) (http.Handler, error)

FullNodeHandler returns a full node handler, to be mounted as-is on the server.

func IsType added in v1.11.0 

func IsType(t repo.RepoType) func(s *Settings) bool

func MinerHandler added in v1.11.0 

func MinerHandler(a api.StorageMiner, permissioned bool) (http.Handler, error)

MinerHandler returns a miner handler, to be mounted as-is on the server.

func MonitorShutdown added in v1.11.0 

func MonitorShutdown(triggerCh <-chan struct{}, handlers ...ShutdownHandler) <-chan struct{}

MonitorShutdown manages shutdown requests, by watching signals and invoking the supplied handlers in order.

It watches SIGTERM and SIGINT OS signals, as well as the trigger channel. When any of them fire, it calls the supplied handlers in order. If any of them errors, it merely logs the error.

Once the shutdown has completed, it closes the returned channel. The caller can watch this channel

func WithEnableLibp2pNode added in v1.13.0 

func WithEnableLibp2pNode(enable bool) func(s *Settings) error

func WithInvokesKey added in v1.9.0 

func WithInvokesKey(i invoke, resApi interface{}) func(s *Settings) error

func WithRepoType added in v1.9.0 

func WithRepoType(repoType repo.RepoType) func(s *Settings) error

Types

type FullOption added in v0.9.1 

type FullOption = Option

func Lite added in v0.9.1 

func Lite(enable bool) FullOption

type HealthHandler added in v1.17.0 

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

func NewLiveHandler added in v1.17.0 

func NewLiveHandler(api lapi.FullNode) *HealthHandler

Check that the node is still working. That is, that it's still processing the chain. If there have been no recent changes, consider the node to be dead.

func NewReadyHandler added in v1.17.0 

func NewReadyHandler(api lapi.FullNode) *HealthHandler

Check if we are ready to handle traffic. 1. sync workers are reasonably up to date. 2. libp2p is servicable

func (*HealthHandler) ServeHTTP added in v1.17.0 

func (h *HealthHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

func (*HealthHandler) SetHealthy added in v1.17.0 

func (h *HealthHandler) SetHealthy(healthy bool)

type Option 

type Option func(*Settings) error

Option is a functional option which can be used with the New function to change how the node is constructed

Options are applied in sequence

func ApplyIf(check func(s *Settings) bool, opts ...Option) Option

func Base added in v1.11.1 

func Base() Option

func ConfigCommon 

func ConfigCommon(cfg *config.Common, enableLibp2pNode bool) Option

Config sets up constructors based on the provided Config

func ConfigFullNode 

func ConfigFullNode(c interface{}) Option

func ConfigStorageMiner 

func ConfigStorageMiner(c interface{}) Option

func Error 

func Error(err error) Option

Error is a special option which returns an error when applied

Options groups multiple options into one

func Override 

func Override(typ, constructor interface{}) Option

Override option changes constructor for a given type

func Repo 

func Repo(r repo.Repo) Option

func StorageMiner 

func StorageMiner(out *api.StorageMiner, subsystemsCfg config.MinerSubsystemConfig) Option

func Test 

func Test() Option

func Unset 

func Unset(typ interface{}) Option

type Settings 

type Settings struct {
	Base   bool // Base option applied
	Config bool // Config option applied
	Lite   bool // Start node in "lite" mode
	// contains filtered or unexported fields
}

type ShutdownHandler added in v1.11.0 

type ShutdownHandler struct {
	Component string
	StopFunc  StopFunc
}

type StopFunc 

type StopFunc func(context.Context) error

func New 

func New(ctx context.Context, opts ...Option) (StopFunc, error)

New builds and starts new Filecoin node

func ServeRPC added in v1.11.0 

func ServeRPC(h http.Handler, id string, addr multiaddr.Multiaddr) (StopFunc, error)

ServeRPC serves an HTTP handler over the supplied listen multiaddr.

This function spawns a goroutine to run the server, and returns immediately. It returns the stop function to be called to terminate the endpoint.

The supplied ID is used in tracing, by inserting a tag in the context.
