const ( // DefaultFlags are passed to the default console log.Logger DefaultFlags = log.Ldate | log.Ltime | log.Lmicroseconds | log.Lshortfile )

var NullLogger = nullLogger{}
NullLogger is a logger that does nothing
Functions ¶
func BootSetup ¶
func BootSetup() error
BootSetup creates a logger meant to be used when running from initramfs, where we want to consider the quiet kernel option.
func Debugf ¶
func Debugf(format string, v ...interface{})
Debugf records something in the debug log
func MockLogger ¶
MockLogger replaces the existing logger with a buffer and returns the log buffer and a restore function.
func NoGuardDebugf ¶
func NoGuardDebugf(format string, v ...interface{})
NoGuardDebugf records something in the debug log
func StartupStageTimestamp ¶
func StartupStageTimestamp(stage string)
StartupStageTimestamp produce snap startup timings message.
func WithLoggerLock ¶
func WithLoggerLock(f func())
WithLoggerLock invokes f with the global logger lock, useful for tests involving goroutines with MockLogger.
Types ¶
type Log ¶
type Log struct {
// contains filtered or unexported fields
}
func (*Log) NoGuardDebug ¶
NoGuardDebug always prints the message, w/o gating it based on environment variables or other configurations.
type Logger ¶
type Logger interface {
// Notice is for messages that the user should see
Notice(msg string)
// Debug is for messages that the user should be able to find if they're debugging something
Debug(msg string)
// NoGuardDebug is for messages that we always want to print (e.g., configurations
// were checked by the caller, etc)
NoGuardDebug(msg string)
}
A Logger is a fairly minimal logging tool.
