MFC 1.62: Fix reading of files that use pax 'size' attribute 2007-10-29T03:28:28+00:00 Tim Kientzle kientzle@FreeBSD.org 2007-10-29T03:28:28+00:00 2c43001f022564824331818ccf7a565374a74342 to store size. In particular, the pax 'size' attribute is required for any file over 8G. This seems to fix tar -cf - | tar -xf - when there are files over 8G in the heirarchy being copied.

This commit updates libarchive to be compatible with 2007-08-18T21:53:25+00:00 Tim Kientzle kientzle@FreeBSD.org 2007-08-18T21:53:25+00:00 68f0154dcf0a18654f729a285d49f5ae81422a3f GNU tar 1.17's implementation of --posix --sparse, at the cost of losing compatibility with GNU tar 1.16. Fortunately, the 1.17 implementation actually makes sense, so the libarchive code is now a bit more straightforward than before. Background: GNU tar 1.16 defined a new way to store sparse files in --posix archives. Unfortunately, the implementation incorrectly inserted several blocks of null padding after each such entry. As a result, non-GNU tar implementations saw the archive as truncated after any sparse entry. This was fixed in GNU tar 1.17 at the cost of losing compatibility with GNU tar 1.16 for this new format (which is not the default, so hopefully rarely used). Libarchive recently gained support for reading the GNU tar 1.16 formats; this commit updates it to read the GNU tar 1.17 variant instead.
