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 IsFifo ¶

func IsFifo(path string) (bool, error)

IsFifo checks if a file is a (named pipe) fifo if the file does not exist then it returns false

func MkdirAllWithACL ¶

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