Example #1

     from edacc import utils

     assert decompressed_data == uncompressed_data
     assert len(compressed_data) > 13 # there should always be a 13 bytes header
     len_bytes = struct.unpack('<Q', compressed_data[5:13])[0]
     assert len_bytes == len(uncompressed_data)

Example #3

 def set_instance(self, uncompressed_instance):
     """ Compresses the instance and sets the instance blob attribute """
     self.instance = "LZMA" + utils.lzma_compress(uncompressed_instance)
