Serhiy Storchaka added the comment:
See also issue15795. It would be good to make shutil, zipfile and tarfile
interfaces consistent.
I think we need more graduated interface matching coretools.
"""
--preserve[=ATTR_LIST]
preserve the specified attributes (default:
mode,ownership,timestamps), if possible additional attributes: context, links,
xattr, all
--no-preserve=ATTR_LIST
don't preserve the specified attributes
"""
This means that we should add preserve_mode, preserve_ownership, preserve_time,
etc parameters. preserve_ownership should control also copying of
suid/sgid/sticky bits. copy()'s defaults will be preserve_mode=True,
preserve_ownership=False, preserve_time=False, copy2()'s defaults
(corresponding to "cp -p" behavior) will be preserve_mode=True,
preserve_ownership=True, preserve_time=True.
