Functions

func EnsureProcessDone

func EnsureProcessDone(p *os.Process) error

EnsureProcessDone makes sure the process has exited completely.

func Errorf

func Errorf(format string, a ...interface{}) error

Errorf is like fmt.Errorf except it translates paths with ReplacePathSeparator when Windows. This is needed because by default '\' escapes.

func Fprintf

func Fprintf(w io.Writer, format string, a ...interface{})

Fprintf is like fmt.Fprintf, but handles EOL according runtime.GOOS. See Sprintf for notes.

func Interrupt

func Interrupt(p *os.Process) error

Interrupt attempts to interrupt the process. It doesn't necessarily kill it.

func IsExecutable

func IsExecutable(f os.FileInfo) bool

IsExecutable returns true if the input can be run as an exec.Cmd

func ProcessGroupAttr

func ProcessGroupAttr() *syscall.SysProcAttr

ProcessGroupAttr sets attributes that ensure exec.Cmd doesn't propagate signals from func-e by default. This is used to ensure shutdown hooks can apply

func ReplacePathSeparator

func ReplacePathSeparator(input string) string

ReplacePathSeparator returns the input unless it is Windows. When Windows, all '/' characters replace with '\'.

func Sprintf

func Sprintf(format string, a ...interface{}) string

Sprintf is like Fprintf is like fmt.Sprintf, except any '\n' in the format are converted according to runtime.GOOS. This allows us to be consistent with Envoy, which handles \r\n on Windows. See also https://github.com/golang/go/issues/28822
