Constants ¶

const OOMScoreMaxKillable = -999

OOMScoreMaxKillable is the maximum score keeping the process killable by the oom killer

Functions ¶

func CreateUnixSocket ¶

func CreateUnixSocket(path string) (net.Listener, error)

CreateUnixSocket creates a unix socket and returns the listener

func ForceRemoveAll ¶

func ForceRemoveAll(path string) error

ForceRemoveAll on unix is just a wrapper for os.RemoveAll

func GetLocalListener ¶

func GetLocalListener(path string, uid, gid int) (net.Listener, error)

GetLocalListener returns a listener out of a unix socket.

func GetOOMScoreAdj ¶

func GetOOMScoreAdj(pid int) (int, error)

GetOOMScoreAdj gets the oom score for a process

func GetOpenFds ¶

func GetOpenFds(pid int) (int, error)

GetOpenFds returns the number of open fds for the process provided by pid

func MkdirAllWithACL ¶

func MkdirAllWithACL(path string, perm os.FileMode) error

MkdirAllWithACL is a wrapper for os.MkdirAll on Unix systems.

func RunningPrivileged ¶

func RunningPrivileged() bool

RunningPrivileged returns true if the effective user ID of the calling process is 0

func RunningUnprivileged ¶

func RunningUnprivileged() bool

RunningUnprivileged returns true if the effective user ID of the calling process is not 0

func SetOOMScore ¶

func SetOOMScore(pid, score int) error

SetOOMScore sets the oom score for the provided pid

Types ¶

type Exit ¶

type Exit struct {
	Pid    int
	Status int
}

Exit is the wait4 information from an exited process

func Reap ¶

func Reap(wait bool) (exits []Exit, err error)

Reap reaps all child processes for the calling process and returns their exit information
