Functions

func CopyRegularFile

func CopyRegularFile(src, dest string) (err error)

func CopySymlink

func CopySymlink(src, dest string) error

func CopyTree

func CopyTree(src, dest string, uidRange *user.UidRange) error

func DirSize

func DirSize(path string) (int64, error)

DirSize takes a path and returns its size in bytes

func EvalSymlinksAlways

func EvalSymlinksAlways(path string) (string, error)

EvalSymlinksAlways behaves like filepath.EvalSymlinks but does not require that all path components must exist.

While filepath.EvalSymlink behaves like `readlink -e` this function behaves like `readlink -m`.

Unlike `readlink` EvalSymlinksAlways might return a relative path.

func GetDeviceInfo

func GetDeviceInfo(path string) (kind rune, major uint64, minor uint64, err error)

GetDeviceInfo returns the type, major, and minor numbers of a device. Kind is 'b' or 'c' for block and character devices, respectively. This does not follow symlinks.

func IsDeviceNode

func IsDeviceNode(path string) bool

IsDeviceNode checks if the given path points to a block or char device. It doesn't follow symlinks.

func IsExecutable

func IsExecutable(path string) bool

IsExecutable checks if the given path points to an executable file by checking the executable bit. Inspired by os.exec.LookPath()

func LUtimesNano

func LUtimesNano(path string, ts []syscall.Timespec) error

TODO(sgotti) waiting for a utimensat functions accepting flags and a LUtimesNano using it in https://github.com/golang/sys/

func Lgetxattr

func Lgetxattr(path string, attr string) ([]byte, error)

Returns a nil slice and nil error if the xattr is not set

func Lsetxattr

func Lsetxattr(path string, attr string, data []byte, flags int) error

func TimeToTimespec

func TimeToTimespec(time time.Time) (ts syscall.Timespec)

TODO(sgotti) use UTIMES_OMIT on linux if Time.IsZero ?
