Functions ¶

func HashBlobBytes ¶

func HashBlobBytes(b []byte) entities.Hash

func HashBlobReader ¶

func HashBlobReader(size int64, r io.Reader) (entities.Hash, error)

func HashBytes ¶

func HashBytes(b []byte) entities.Hash

func HashFileBlob ¶

func HashFileBlob(fileName string) (entities.Hash, int64, error)

func NewHasher ¶

func NewHasher() hash.Hash

func ObjectJSONDecode ¶

func ObjectJSONDecode(o JSONObject, magic ObjectType, hash Hash, content []byte) error

func ObjectJSONEncode ¶

func ObjectJSONEncode(o JSONObject, magic ObjectType) error

func ParseHeader ¶

func ParseHeader(buf []byte) (string, int64, error)

func PrependHeaderReader ¶

func PrependHeaderReader(r io.Reader, objType string, size int64) io.Reader

func PutHeader ¶

func PutHeader(objType string, content []byte) ([]byte, error)

PutHeader expects to receive an object type with the content of the object prefixed with a fixed header of MaxHeaderSize bytes. It will put the correct git header right before the actual content. It will return a slice where the actual content begins and includes the actual content.

func ReadBlob ¶

func ReadBlob(r io.Reader) ([]byte, error)

func ReadBlobHeader ¶

func ReadBlobHeader(r io.Reader) (int64, error)

func ReadHeader ¶

func ReadHeader(r io.Reader) (string, int64, error)

func WriteHeader ¶

func WriteHeader(w io.Writer, objType string, size int64) error
