Constants

View Source
const Version = "0.1.0"

Version of the client.

View Source
const VersionHeader = "X-Client-Version"

VersionHeader is sent with every request.

Variables

View Source
var DefaultCircuitBreakerSettings = CircuitBreakerSettings{
	MaxConcurrentRequests:  100,
	RequestVolumeThreshold: 20,
	SleepWindow:            5000,
	ErrorPercentThreshold:  90,
}

DefaultCircuitBreakerSettings describes the default circuit parameters.

Functions

func WithRetryPolicy added in v0.2.0

func WithRetryPolicy(ctx context.Context, retryPolicy RetryPolicy) context.Context

WithRetryPolicy returns a new context that overrides the client object's retry policy.

Types

type CircuitBreakerSettings added in v0.1.3

type CircuitBreakerSettings struct {
	// MaxConcurrentRequests is the maximum number of concurrent requests
	// the client can make at the same time. Default: 100.
	MaxConcurrentRequests int
	// RequestVolumeThreshold is the minimum number of requests needed
	// before a circuit can be tripped due to health. Default: 20.
	RequestVolumeThreshold int
	// SleepWindow how long, in milliseconds, to wait after a circuit opens
	// before testing for recovery. Default: 5000.
	SleepWindow int
	// ErrorPercentThreshold is the threshold to place on the rolling error
	// rate. Once the error rate exceeds this percentage, the circuit opens.
	// Default: 90.
	ErrorPercentThreshold int
}

CircuitBreakerSettings are the parameters that govern the client's circuit breaker.

type Client

type Client interface {
}

Client defines the methods available to clients of the swagger-test service.

type ExponentialRetryPolicy added in v1.0.0

type ExponentialRetryPolicy struct{}

ExponentialRetryPolicy defines an exponential retry policy

func (ExponentialRetryPolicy) Backoffs added in v1.0.0

func (ExponentialRetryPolicy) Backoffs() []time.Duration

Backoffs returns five backoffs with exponentially increasing wait times between requests: 100, 200, 400, 800, and 1600 milliseconds +/- up to 5% jitter.

func (ExponentialRetryPolicy) Retry added in v1.0.0

func (ExponentialRetryPolicy) Retry(req *http.Request, resp *http.Response, err error) bool

type HystrixSSEEvent added in v0.1.3

type HystrixSSEEvent struct {
	Type                            string `json:"type"`
	Name                            string `json:"name"`
	RequestCount                    int    `json:"requestCount"`
	ErrorCount                      int    `json:"errorCount"`
	ErrorPercentage                 int    `json:"errorPercentage"`

	RollingCountFailure             int    `json:"rollingCountFailure"`
	RollingCountFallbackFailure     int    `json:"rollingCountFallbackFailure"`
	RollingCountFallbackSuccess     int    `json:"rollingCountFallbackSuccess"`
	RollingCountShortCircuited      int    `json:"rollingCountShortCircuited"`
	RollingCountSuccess             int    `json:"rollingCountSuccess"`
	RollingCountThreadPoolRejected  int    `json:"rollingCountThreadPoolRejected"`
	RollingCountTimeout             int    `json:"rollingCountTimeout"`
	CurrentConcurrentExecutionCount int    `json:"currentConcurrentExecutionCount"`
	LatencyTotalMean                int    `json:"latencyTotal_mean"`
}

HystrixSSEEvent is emitted by hystrix-go via server-sent events. It describes the state of a circuit.

type MockClient

	// contains filtered or unexported fields
}

MockClient is a mock of Client interface

func NewMockClient

func NewMockClient(ctrl *gomock.Controller) *MockClient

NewMockClient creates a new mock instance

Retry always returns false.

type RetryPolicy added in v0.2.0

type RetryPolicy interface {
	// Backoffs returns the number and timing of retry attempts.
	Backoffs() []time.Duration
	// Retry receives the http request, as well as the result of
	// net/http.Client's `Do` method.
	Retry(*http.Request, *http.Response, error) bool
}

type WagClient

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

WagClient is used to make requests to the swagger-test service.

func New

func New(basePath string) *WagClient

New creates a new client. The base path and http transport are configurable.

func NewFromDiscovery

func NewFromDiscovery() (*WagClient, error)

NewFromDiscovery creates a client from the discovery environment variables. This method requires the three env vars: SERVICE_SWAGGER_TEST_HTTP_(HOST/PORT/PROTO) to be set. Otherwise it returns an error.
