Functions

func CachedLogOutput

func CachedLogOutput() string

Retrieves cached log output.

func EnableLogCaching

func EnableLogCaching(maxLines, maxMem int)

EnableLogCaching enables in memory caching of log output. Caches up to maxLines, but no more than maxMem bytes. Cached output can later be queried with CachedOutput.

func Error

func Error(err error)

func Errorf

func Errorf(msg string, args ...interface{})

func Fatal

func Fatal(err error)

func Fatalf

func Fatalf(msg string, args ...interface{})

func Log

func Log(v int, msg string)

func Logf

func Logf(v int, msg string, args ...interface{})

func SetName

func SetName(name string)

If the name is set, it will be displayed for all logs.

func SyzFatal

func SyzFatal(err error)

func SyzFatalf

func SyzFatalf(msg string, args ...interface{})

SyzFatalf-reported errors are parsed by syzkaller as if they were kernel bugs.

func V

func V(level int) bool

V reports whether verbosity at the call site is at least the requested level. See https://pkg.go.dev/github.com/golang/glog#V for details.

Types

type VerboseWriter

type VerboseWriter int

func (VerboseWriter) Write

func (w VerboseWriter) Write(data []byte) (int, error)
