Functions

func NewFeatureUsageAggregator

func NewFeatureUsageAggregator() (core.Aggregator, error)

NewFeatureUsageAggregator constructs a new FeatureUsageAggregator

Types

type FeatureUsageAggregator

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

FeatureUsageAggregator implements the Aggregator interface for heavy-weight feature usage aggregates and script creation/harvesting

func (*FeatureUsageAggregator) DumpToPostgresql

func (agg *FeatureUsageAggregator) DumpToPostgresql(ctx *core.AggregationContext, sqlDb *sql.DB) error

DumpToMongresql handles tuple and blob insertion for feature usage (mono/polymorphic callsites), script creation, and script archiving

func (*FeatureUsageAggregator) DumpToStream

func (agg *FeatureUsageAggregator) DumpToStream(ctx *core.AggregationContext, stream io.Writer) error

DumpToStream sends feature/script/blob data to stdout for inspection

func (*FeatureUsageAggregator) IngestRecord

func (agg *FeatureUsageAggregator) IngestRecord(ctx *core.ExecutionContext, lineNumber int, op byte, fields []string) error

IngestRecord parses a trace/callsite record and aggregates API feature usage

type UsageInfo

type UsageInfo struct {
	// Active security origin
	Origin string

	// Active script
	Script *core.ScriptInfo

	// Character offset into script (determines "call site")
	Offset int

	// Feature name (generally, RECEVER_CTOR_NAME.ITEM_NAME)
	Name string

	// Usage mode ('g' get, 'c' call, 's' set, 'n' new-style call)
	Usage rune
}

UsageInfo provides the key type for our map of feature-tuple aggregates
