Functions

func Close

func Close()

func Critical

func Critical(skip int, format string, v ...interface{})

func Error(skip int, format string, v ...interface{})

func Fatal

func Fatal(skip int, format string, v ...interface{})

func Info

func Info(format string, v ...interface{})

func NewGitLogger

func NewGitLogger(logPath string)

FIXME: use same log level as other loggers.

Types

type FileLogWriter

type FileLogWriter struct {
	*log.Logger

	// The opened file
	Filename string `json:"filename"`

	Maxlines int `json:"maxlines"`

	// Rotate at size
	Maxsize int `json:"maxsize"`

	// Rotate daily
	Daily   bool  `json:"daily"`
	Maxdays int64 `json:"maxdays"`

	Rotate bool `json:"rotate"`

	Level int `json:"level"`
	// contains filtered or unexported fields
}

FileLogWriter implements LoggerInterface. It writes messages by lines limit, file size limit, or time frequency.

func (*FileLogWriter) Destroy

func (w *FileLogWriter) Destroy()

destroy file logger, close file writer.

func (*FileLogWriter) DoRotate

func (w *FileLogWriter) DoRotate() error

DoRotate means it need to write file in new file. new file name like xx.log.2013-01-01.2

func (*FileLogWriter) Flush

func (w *FileLogWriter) Flush()

flush file logger. there are no buffering messages in file logger in memory. flush file means sync file from disk.

func (*FileLogWriter) Init

func (w *FileLogWriter) Init(config string) error

Init file logger with json config. config like:

{
"filename":"log/gogs.log",
"maxlines":10000,
"maxsize":1<<30,
"daily":true,
"maxdays":15,
"rotate":true
}

func (*FileLogWriter) StartLogger

func (w *FileLogWriter) StartLogger() error

start file logger. create log file and set to locker-inside file writer.

func (*FileLogWriter) WriteMsg

func (w *FileLogWriter) WriteMsg(msg string, skip, level int) error

write logger message into file.

type LogLevel

type LogLevel int

type Logger

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

Logger is default logger in beego application. it can contain several providers and log message into all providers.

var (
	GitLogger *Logger
)

func (*Logger) Close

func (l *Logger) Close()

Close closes logger, flush all chan data and destroy all adapter instances.

func (*Logger) Critical

func (l *Logger) Critical(skip int, format string, v ...interface{})

func (*Logger) Debug

func (l *Logger) Debug(format string, v ...interface{})

func (*Logger) DelLogger

func (l *Logger) DelLogger(adapter string) error

DelLogger removes a logger adapter instance.

func (*Logger) Error

func (l *Logger) Error(skip int, format string, v ...interface{})

func (*Logger) Fatal

func (l *Logger) Fatal(skip int, format string, v ...interface{})

func (*Logger) Flush

func (l *Logger) Flush()

Flush flushs all chan data.

func (*Logger) Info

func (l *Logger) Info(format string, v ...interface{})

func (*Logger) SetLogger

func (l *Logger) SetLogger(adapter string, config string) error

SetLogger sets new logger instance with given logger adapter and config.

func (*Logger) StartLogger

func (l *Logger) StartLogger()

StartLogger starts logger chan reading.

func (*Logger) Trace

func (l *Logger) Trace(format string, v ...interface{})

func (*Logger) Warn

func (l *Logger) Warn(format string, v ...interface{})

type LoggerInterface

type LoggerInterface interface {
	Init(config string) error
	WriteMsg(msg string, skip, level int) error
	Destroy()
	Flush()
}

LoggerInterface represents behaviors of a logger provider.

func NewFileWriter

func NewFileWriter() LoggerInterface

create a FileLogWriter returning as LoggerInterface.

type MuxWriter

type MuxWriter struct {
	sync.Mutex
	// contains filtered or unexported fields
}

an *os.File writer with locker.

func (*MuxWriter) SetFd

func (l *MuxWriter) SetFd(fd *os.File)

set os.File in writer.

func (*MuxWriter) Write

func (l *MuxWriter) Write(b []byte) (int, error)

write to os.File.
