In the initial implementation of reproducible tarballs, they were
missing directory entries, while .zip archives had them. It meant
that on extracting the tarball, on-disk directory entries got the
current timestamp.
This patch fixes this by including directory entries in the tarball,
with reproducible timestamps. It also moves sorting inside tar,
to ensure reproducible directory entry timestamps on extract
(without the need of
--delay-directory-restore
option, whenextracting with GNU tar. BSD tar got that right by default.)
--sort=
option was introduced in GNU tar 1.28 (2014-07-28)Ref: #13299 (comment)
Follow-up to 860cd5f #13299
Closes #13322
