ApplyHeader updates file owner, mtime, and permission bits according to header. It doesn't change size or type (i.e file to dir).

func IsSimilarHeader

func IsSimilarHeader(h *tar.Header, nh *tar.Header, ignoreTime bool) (bool, error)

IsSimilarHeader returns if the given headers are describing similar entries.

func NewGzipReader

func NewGzipReader(r io.Reader) (io.ReadCloser, error)

NewGzipReader returns a new gzip reader.

func NewGzipWriter

func NewGzipWriter(w io.Writer) (io.WriteCloser, error)

NewGzipWriter returns a new gzip writer with compression level.

func SetCompressionLevel

func SetCompressionLevel(compressionLevelStr string) error

SetCompressionLevel sets global var CompressionLevel.

func Untar

func Untar(r io.Reader, dir string) error

Untar reads the tar file from r and writes it into dir.

func WriteEntry

func WriteEntry(w *tar.Writer, src string, h *tar.Header) error
