Functions

func NewBoundedExecer

func NewBoundedExecer(memCap scootexecer.Memory, getMemUtilization func() (int64, error), stat stats.StatsReceiver) *execer

NewBoundedExecer returns an execer with a ProcGetter and, if non-zero values are provided, a memCap, overriding memory utilization function, and a StatsReceiver

func NewProcWatcher

func NewProcWatcher() *procWatcher

Types

type ProcInfo

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

func (ProcInfo) Pid

func (p ProcInfo) Pid() int

type ProcessWatcher

type ProcessWatcher interface {
	GetProcs() (map[int]ProcInfo, error)
	MemUsage(int) (scootexecer.Memory, error)
	LogProcs(*process, log.Level, io.Writer)
}

Used for mocking memCap monitoring

type WriterDelegater

type WriterDelegater interface {
	// Return an underlying Writer. Why? Because some methods type assert to
	// a more specific type and are more clever (e.g., if it's an *os.File, hook it up
	// directly to a new process's stdout/stderr.)
	// We care about this cleverness, so Output both is-a and has-a Writer
	// Cf. runner/runners/local_output.go
	WriterDelegate() io.Writer
