While upgrade instance from python2 to python3, i found when read old BigFile object such as Data Stream, it raise error below

  Module erp5.component.document.erp5_version.BigFile, line 105, in getData
    return btree.read(0, len(btree))
  Module erp5.component.module.erp5_version.BTreeData, line 182, in read
    return b''.join(self.iterate(offset, size))
TypeError: sequence item 0: expected a bytes-like object, str found

for the new object created after python3 upgrade, i don't have such error

it seems that BTreeData contains mixed data: string and bytes
