示例1: ControlWorkSpec

// ControlWorkSpec makes changes to a work spec that are not directly
// reflected in the work spec definition.  This allows work specs to
// be paused or to stop generating new continuous jobs.
// ControlWorkSpecOptions has a complete listing of what can be done.
func (jobs *JobServer) ControlWorkSpec(workSpecName string, options map[string]interface{}) (bool, string, error) {
	var (
		cwsOptions ControlWorkSpecOptions
		decoder    *mapstructure.Decoder
		err        error
		metadata   mapstructure.Metadata
		workSpec   coordinate.WorkSpec
		wsMeta     coordinate.WorkSpecMeta
	)

	workSpec, err = jobs.Namespace.WorkSpec(workSpecName)
	if err == nil {
		// We care a lot about "false" vs. not present for
		// these things.  Manually create the decoder.
		config := mapstructure.DecoderConfig{
			Result:   &cwsOptions,
			Metadata: &metadata,
		}
		decoder, err = mapstructure.NewDecoder(&config)
	}
	if err == nil {
		err = decoder.Decode(options)
	}

	// Get the existing metadata, then change it based on what
	// we got provided
	if err == nil {
		wsMeta, err = workSpec.Meta(false)
	}
	if err == nil {
		for _, key := range metadata.Keys {
			switch key {
			case "Continuous":
				wsMeta.Continuous = cwsOptions.Continuous
			case "Status":
				wsMeta.Paused = cwsOptions.Status == Paused
			case "Weight":
				wsMeta.Weight = cwsOptions.Weight
			case "Interval":
				wsMeta.Interval = time.Duration(cwsOptions.Interval) * time.Second

示例2: TestMetaContinuous

// TestMetaContinuous specifically checks that you cannot enable the
// "continuous" flag on non-continuous work specs.
func TestMetaContinuous(t *testing.T) {
	var (
		err       error
		namespace coordinate.Namespace
		spec      coordinate.WorkSpec
		meta      coordinate.WorkSpecMeta
	)

	namespace, err = Coordinate.Namespace("TestMetaContinuous")
	if !assert.NoError(t, err) {
		return
	}
	defer namespace.Destroy()

	spec, err = namespace.SetWorkSpec(map[string]interface{}{
		"name":   "spec",
		"min_gb": 1,
	})
	if !assert.NoError(t, err) {

示例3: GetWorkSpecMeta

// GetWorkSpecMeta returns a set of control options for a given work
// spec.  The returned map has the full set of keys that
// ControlWorkSpec() will accept.
func (jobs *JobServer) GetWorkSpecMeta(workSpecName string) (result map[string]interface{}, _ string, err error) {
	var (
		workSpec coordinate.WorkSpec
