}

ClientSDKFlag contains the flag evaluation results for a single flag in ClientSDKData.

type ClientSDKFlagWithKey

}

ClientSDKFlagWithKey is used only in stream updates, where the key is within the same object.

type DataItemKind 

type DataItemKind string

type Event 

type Event ldvalue.Value

Event is a JSON representation of an event. For convenience, this is stored as ldvalue.Value.

func (Event) AsValue 

func (e Event) AsValue() ldvalue.Value

func (Event) JSONString 

func (e Event) JSONString() string

func (Event) Kind 

func (e Event) Kind() string

func (Event) MarshalJSON 

func (e Event) MarshalJSON() ([]byte, error)

func (Event) String 

func (e Event) String() string

func (*Event) UnmarshalJSON 

func (e *Event) UnmarshalJSON(data []byte) error

type Events 

type Events []Event

Events is an array of events. This specialized type provides helper methods.

func (Events) JSONString 

func (es Events) JSONString() string

type EventsService 

type EventsService struct {
	AnalyticsEventPayloads chan Events
	// contains filtered or unexported fields
}

EventsService is a simulation of the LaunchDarkly event-recorder service, allowing tests to receive event data from an SDK. This is a low-level component that tests normally don't need to interact with directly; most tests use the sdktests.SDKEventSink facade.

func NewEventsService 

func NewEventsService(sdkKind SDKKind, logger framework.Logger) *EventsService

func (*EventsService) AwaitAnalyticsEventPayload 

func (s *EventsService) AwaitAnalyticsEventPayload(timeout time.Duration) (Events, bool)

func (*EventsService) ServeHTTP 

func (s *EventsService) ServeHTTP(w http.ResponseWriter, r *http.Request)

func (*EventsService) SetHostTimeOverride 

func (s *EventsService) SetHostTimeOverride(t time.Time)

func (*EventsService) SetIgnoreDuplicatePayload 

func (s *EventsService) SetIgnoreDuplicatePayload(ignore bool)

SetIgnoreDuplicatePayload sets whether we should keep track of X-LaunchDarkly-Payload-Id header values we have seen at this endpoint and ignore any posts containing the same header value. This is true by default; tests would only set it to false if they want to verify that a failed post was retried.

The rationale for this being the default behavior is that an SDK might, due to unpredictable network issues, think an event post had failed when it really succeeded, and retry the post. We don't want that to disrupt tests. The payload ID is always the same in the case of a retry for this very reason-- it allows event-recorder to ignore accidental redundant posts. We trust that SDKs will generate reasonably unique payload IDs for posts that are not retries.

type MockBigSegmentStoreService 

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

MockBigSegmentStoreService is the low-level component providing the mock endpoints for the Big Segments test fixture. The higher-level component sdktests.BigSegmentStore decorates this to make it more convenient to use in test logic.

func NewMockBigSegmentStoreService 

func NewMockBigSegmentStoreService(
	getMetadata func() (ldtime.UnixMillisecondTime, error),
	getContextMembership func(string) (map[string]bool, error),
	logger framework.Logger,
) *MockBigSegmentStoreService

func (*MockBigSegmentStoreService) ServeHTTP 

func (m *MockBigSegmentStoreService) ServeHTTP(w http.ResponseWriter, r *http.Request)

type PollingService 

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

func NewPollingService 

func NewPollingService(
	initialData SDKData,
	sdkKind SDKKind,
	debugLogger framework.Logger,
) *PollingService

func (*PollingService) ServeHTTP 

func (p *PollingService) ServeHTTP(w http.ResponseWriter, r *http.Request)

func (*PollingService) SetData 

func (p *PollingService) SetData(data SDKData)

func (*PollingService) SetEtag 

func (p *PollingService) SetEtag(etag string)

type SDKData 

type SDKData interface {
	Serialize() []byte
}

func BlockingUnavailableSDKData 

func BlockingUnavailableSDKData(sdkKind SDKKind) SDKData

BlockingUnavailableSDKData returns an object that will cause the mock streaming service *not* to provide any data. It will accept connections, but then hang. This allows us to simulate a state where the SDK client times out without initializing, because it has not received any "put" event.

func EmptyData 

func EmptyData(sdkKind SDKKind) SDKData

type SDKKind 

type SDKKind string
const (
	ServerSideSDK SDKKind = "server"
	MobileSDK     SDKKind = "mobile"
	JSClientSDK   SDKKind = "jsclient"
)

func (SDKKind) IsClientSide 

func (k SDKKind) IsClientSide() bool

func (SDKKind) IsServerSide 

func (k SDKKind) IsServerSide() bool

type ServerSDKData 

type ServerSDKData map[DataItemKind]map[string]json.RawMessage

ServerSDKData contains simulated LaunchDarkly environment data for a server-side SDK.

This includes the full JSON configuration of every flag and segment, in the same format that is used in streaming and polling responses.

func EmptyServerSDKData 

func EmptyServerSDKData() ServerSDKData

func (ServerSDKData) JSONString 

func (d ServerSDKData) JSONString() string

func (ServerSDKData) Serialize 

func (d ServerSDKData) Serialize() []byte

	// contains filtered or unexported fields
}

func NewServerSDKDataBuilder 

func NewServerSDKDataBuilder() *ServerSDKDataBuilder

func (*ServerSDKDataBuilder) Build 

func (b *ServerSDKDataBuilder) Build() ServerSDKData

func (*ServerSDKDataBuilder) Flag

func (*ServerSDKDataBuilder) RawSegment 

func (b *ServerSDKDataBuilder) RawSegment(key string, data json.RawMessage) *ServerSDKDataBuilder

func (*ServerSDKDataBuilder) Segment 

func (b *ServerSDKDataBuilder) Segment(segments ...ldmodel.Segment) *ServerSDKDataBuilder

type StreamingService 

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

func NewStreamingService 

func NewStreamingService(
	initialData SDKData,
	sdkKind SDKKind,
	debugLogger framework.Logger,
) *StreamingService

func (*StreamingService) PushDelete 

func (s *StreamingService) PushDelete(namespace, key string, version int)

func (*StreamingService) PushEvent 

func (s *StreamingService) PushEvent(eventName string, eventData interface{})

Sends an SSE event to all clients that are currently connected to the stream-- or, if no client has connected yet, queues the event so that it will be sent (after the initial data) to the first client that connects. (The latter is necessary to avoid race conditions, since even after a connection is received on the stream endpoint, it is hard for the test logic to know when the HTTP handler has actually created a stream subscription for that connection. If we called the eventsource Publish method before a subscription existed, the event would be lost.)

func (*StreamingService) PushUpdate 

func (s *StreamingService) PushUpdate(namespace, key string, data json.RawMessage)

func (*StreamingService) RefreshAll 

func (s *StreamingService) RefreshAll()

func (*StreamingService) Replay 

func (s *StreamingService) Replay(channel, id string) chan eventsource.Event

func (*StreamingService) ServeHTTP 

func (s *StreamingService) ServeHTTP(w http.ResponseWriter, r *http.Request)

func (*StreamingService) SetInitialData 

func (s *StreamingService) SetInitialData(data SDKData)
