Variables

var StopProfiling = os.Getenv("SONIC_STOP_PROFILING") != ""

StopProfiling is used to stop traceback introduced by SIGPROF while native code is running. WARN: this option is only a workaround for traceback issue (https://github.com/bytedance/sonic/issues/310), and will be dropped when the issue is fixed.

var TickerInterval = time.Millisecond * 50

TickerInterval defines the interval used by the ticker in Check* functions.

Functions

func CheckContext

func CheckContext(ctx context.Context, t *testing.T) func()

CheckContext snapshots the currently-running goroutines and returns a function to be run at the end of tests to see whether any goroutines leaked.

func GcwbAddr

func GcwbAddr() uintptr

func GetCallerFrame

func GetCallerFrame(skip int) (frame runtime.Frame, ok bool)

func GetFuncName

func GetFuncName(i interface{}) string

GetFuncName return the function name

func GoID

func GoID() (id uint64)

GoID returns the ID of current goroutine.

func MoreStack

func MoreStack(size uintptr)

func StartProf

func StartProf()

func StopProf

func StopProf()
