Functions ¶
func NewRecordingInterceptor ¶ added in v1.2.0
func NewRecordingInterceptor(filename string) (grpc.UnaryClientInterceptor, error)
NewRecordingInterceptor returns a grpc.UnaryClientInterceptor that logs outgoing requests to file.
func ReplayFile ¶ added in v1.2.0
func ReplayFile(ctx context.Context, r io.Reader, cl trillian.TrillianMapClient, write trillian.TrillianMapWriteClient, mapmap map[int64]int64) error
ReplayFile reads recorded gRPC requests and re-issues them using the given client. If a request has a MapId field, and its value is present in mapmap, then the MapId field is replaced before replay.
Types ¶
type Choice ¶ added in v1.0.3
type Choice string
Choice is a readable representation of a choice about how to perform a hammering operation.
type MapBias ¶
type MapBias struct {
Bias map[MapEntrypointName]int
// InvalidChance gives the odds of performing an invalid operation, as the N in 1-in-N.
InvalidChance map[MapEntrypointName]int
// contains filtered or unexported fields
}
MapBias indicates the bias for selecting different map operations.
type MapConfig ¶
type MapConfig struct {
MapID int64 // 0 to use an ephemeral tree
MetricFactory monitoring.MetricFactory
Client trillian.TrillianMapClient
Write trillian.TrillianMapWriteClient
Admin trillian.TrillianAdminClient
RandSource rand.Source
EPBias MapBias
LeafSize, ExtraSize uint
MinLeavesR, MaxLeavesR int
MinLeavesW, MaxLeavesW int
Operations uint64
EmitInterval time.Duration
RetryErrors bool
OperationDeadline time.Duration
// NumCheckers indicates how many separate inclusion checker goroutines
// to run. Note that the behaviour of these checkers is not governed by
// RandSource.
NumCheckers int
// KeepFailedTree indicates whether ephemeral trees should be left intact
// after a failed hammer run.
KeepFailedTree bool
}
MapConfig provides configuration for a stress/load test.
type MapEntrypointName ¶
type MapEntrypointName string
MapEntrypointName identifies a Map RPC entrypoint
