var VersionWithMeta = func() string { v := VersionStr() if VersionMeta != "" { v += "-" + VersionMeta } return v }
VersionWithMeta holds the textual version string including the metadata.
Functions ¶
func BlockBySignal ¶
func BlockBySignal()
func BlockBySignalAndCancel ¶
func BlockBySignalAndCancel(cancel context.CancelFunc, duration time.Duration)
func FindPrefixedEnvVars ¶
FindPrefixedEnvVars finds prefixed environment variables.
func GeneratePID ¶
func IsExported ¶
func IsExported(f reflect.StructField) bool
IsExported reports whether f is exported. https://golang.org/pkg/reflect/#StructField
func PrintStack ¶
func PrintStack()
PrintStack prints to standard error the stack trace returned by runtime.Stack.
func RunCPUProfile ¶
func RunCPUProfile() func()
RunCPUProfile Run starts up stuff at the beginning of a main function, and returns a function to defer until the function completes. It should be used like this:
func main() {
defer sys.RunCPUProfile()()
... stuff ...
}
func RunMemProfile ¶
func RunMemProfile() func()
func SignalContext ¶
func Stack ¶
func Stack() []byte
Stack returns a formatted stack trace of the goroutine that calls it. It calls runtime.Stack with a large enough buffer to capture the entire trace.
func VersionWithCommit ¶
