Overview

Package logger implements a multi-output leveled logger.

Other packages use tagged logger to send log messages to shared (process-wide) logging engine. The shared logging engine dispatches to multiple log systems. The log level can be set separately per log system.

Logging is asynchronous and does not block the caller. Message formatting is performed by the caller goroutine to avoid incorrect logging of mutable state.

Functions

func AddLogSystem 

func AddLogSystem(sys LogSystem)

AddLogSystem starts printing messages to the given LogSystem.

func Flush 

func Flush()

Flush waits until all current log messages have been dispatched to the active log systems.

func Reset 

func Reset()

Reset removes all active log systems. It blocks until all current messages have been delivered.

type LogSystem 

type LogSystem interface {
	GetLogLevel() LogLevel

}

LogSystem is implemented by log output devices. All methods can be called concurrently from multiple goroutines.

Example 
filename := "test.log"
file, _ := os.OpenFile(filename, os.O_RDWR|os.O_CREATE, os.ModePerm)
fileLog := NewStdLogSystem(file, 0, WarnLevel)
AddLogSystem(fileLog)

stdoutLog := NewStdLogSystem(os.Stdout, 0, WarnLevel)
AddLogSystem(stdoutLog)

NewLogger("TAG").Warnln("reactor meltdown") // writes to both logs

Output:

func New 

func New(datadir string, logFile string, logLevel int, logFormat string) LogSystem

func NewRawLogSystem 

func NewRawLogSystem(writer io.Writer, flags int, level LogLevel) LogSystem

NewRawLogSystem creates a LogSystem that prints to the given writer without adding extra information. Suitable for preformatted output

func NewStdLogSystem 

func NewStdLogSystem(writer io.Writer, flags int, level LogLevel) LogSystem

NewStdLogSystem creates a LogSystem that prints to the given writer. The flag values are defined package log.

type Logger 

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

A Logger prints messages prefixed by a given tag. It provides named Printf and Println style methods for all loglevels. Each ethereum component should have its own logger with a unique prefix.

Example 
logger := NewLogger("TAG")
logger.Infoln("so awesome")            // prints [TAG] so awesome
logger.Infof("this %q is raw", "coin") // prints [TAG] this "coin" is raw
