Constants

const (
	// ConnectionStatusDisconnected is the default state
	ConnectionStatusDisconnected = ConnectionStatus("disconnected")
	// ConnectionStatusConnected is used when the client is successfully connected
	ConnectionStatusConnected = ConnectionStatus("connected")
	// ConnectionStatusError is used when there is an error
	ConnectionStatusError = ConnectionStatus("error")
)

const (
	ExplorerTextMessage   = websocket.TextMessage
	ExplorerBinaryMessage = websocket.BinaryMessage
)

const CloseTimeout = 100 * time.Millisecond

const SendBufferSize = 100

SendBufferSize is the number of messages to keep in the buffer before dropping additional ones

Variables

var (
	// ErrReceiveTimeout is returned when no message is received after a
	// specified duration in Receive
	ErrReceiveTimeout = errors.New("timeout waiting for message")
)

Functions

func InsertSyncEventForJobRun

func InsertSyncEventForJobRun(db *gorm.DB, run *models.JobRun) error

InsertSyncEventForJobRun generates an event for a change to job_runs

Types

type ConnectionStatus

type ConnectionStatus string

type ExplorerClient

type ExplorerClient interface {
	service.Service
	Url() url.URL
	Status() ConnectionStatus
	Send(context.Context, []byte, ...int)
	Receive(context.Context, ...time.Duration) ([]byte, error)
}

ExplorerClient encapsulates all the functionality needed to push run information to explorer.

func NewExplorerClient

func NewExplorerClient(url *url.URL, accessKey, secret string, loggingArgs ...bool) ExplorerClient

NewExplorerClient returns a stats pusher using a websocket for delivery.

type NoopExplorerClient

type NoopExplorerClient struct{}

func (NoopExplorerClient) Close

func (NoopExplorerClient) Close() error

func (NoopExplorerClient) Healthy

func (NoopExplorerClient) Healthy() error

func (NoopExplorerClient) Ready

func (NoopExplorerClient) Ready() error

func (NoopExplorerClient) Receive

func (NoopExplorerClient) Receive(context.Context, ...time.Duration) ([]byte, error)

func (NoopExplorerClient) Send

func (NoopExplorerClient) Send(context.Context, []byte, ...int)

func (NoopExplorerClient) Start

func (NoopExplorerClient) Start() error

func (NoopExplorerClient) Status

func (NoopExplorerClient) Status() ConnectionStatus

func (NoopExplorerClient) Url

func (NoopExplorerClient) Url() url.URL

type NoopStatsPusher

type NoopStatsPusher struct{}

func (NoopStatsPusher) AllSyncEvents

func (NoopStatsPusher) AllSyncEvents(cb func(models.SyncEvent) error) error

func (NoopStatsPusher) Close

func (NoopStatsPusher) Close() error

func (NoopStatsPusher) GetStatus

func (NoopStatsPusher) GetStatus() ConnectionStatus

func (NoopStatsPusher) GetURL

func (NoopStatsPusher) GetURL() url.URL

func (NoopStatsPusher) Healthy

func (NoopStatsPusher) Healthy() error

func (NoopStatsPusher) PushNow

func (NoopStatsPusher) PushNow()

func (NoopStatsPusher) Ready

func (NoopStatsPusher) Ready() error

func (NoopStatsPusher) Start

func (NoopStatsPusher) Start() error

type StatsPusher

type StatsPusher interface {
	service.Service
	PushNow()
	GetURL() url.URL
	GetStatus() ConnectionStatus
	AllSyncEvents(cb func(models.SyncEvent) error) error
}

StatsPusher polls for events and pushes them via a WebSocketClient. Events are consumed by the Explorer. Currently there is only one event type: an encoding of a JobRun.

func NewStatsPusher

func NewStatsPusher(db *gorm.DB, explorerClient ExplorerClient, afters ...utils.Afterer) StatsPusher

NewStatsPusher returns a new StatsPusher service

type SyncJobRunPresenter

type SyncJobRunPresenter struct {
	*models.JobRun
}

SyncJobRunPresenter presents a JobRun for synchronization purposes

func (SyncJobRunPresenter) MarshalJSON

func (p SyncJobRunPresenter) MarshalJSON() ([]byte, error)

MarshalJSON returns the JobRun as JSON

type TxStatus

type TxStatus string

TxStatus indicates if a transaction is fulfilled or not

const (
	// StatusFulfilledRunLog indicates that a ChainlinkFulfilled event was
	// detected in the transaction receipt.
	StatusFulfilledRunLog TxStatus = "fulfilledRunLog"
	// StatusNoFulfilledRunLog indicates that no ChainlinkFulfilled events were
	// detected in the transaction receipt.
	StatusNoFulfilledRunLog = "noFulfilledRunLog"
)
