When the same file is added several times to the archive, count
correctly the number of hard links. See also 37ddfb0b.
* src/create.c (dump_hard_link): Don't decrease nlink if it is 0.
* tests/link04.at: Test -cl options.
Changes proposed by Denis Excoffier.
* NEWS: Fix typos.
* doc/tar.texi: Fix typos. Improve recipe for creation of binary
equivalent archives.
* src/create.c (write_extended): Use the value of the
--mtime option (if specified) as the default for exthdr.mtime.
* src/xheader.c (xheader_store): Create the header if at least
one override is supplied in --pax-option.
List posix archives containing sparse files >8GB correctly and do not fail.
This fixes also bug in format of listing for sparse files >8GB - now the
real size is printed instead of the effective one (this is not strictly
posix format related).
* src/list.c: Remove redundant assignment.
* src/tar.h: Add new 'real_size' and 'real_size_set' fields in
tar_stat_info struct.
* src/xheader.c: Correctly handle (especially sparse) file sizes directly in
xheader_decode().
* configure.ac (TAR_COND_GRANTPT): Define conditional depending
on whether grantpt is available.
* gnulib.modules: Remove grantpt. It relies upon a helper binary
pt_chown which it installs and which is useless in the testsuite.
* tests/Makefile.am [TAR_COND_GRANTPT]: Build ttyemu
* tests/iotty.at: Skip test if ttyemu is not build.
* tests/ttyemu.c (noecho): Fix error message
(main): Use TIOCSCTTY if it is defined.
* src/checkpoint.c (getwidth, format_checkpoint_string):
Use long and strtol, not int, to avoid overflow issues.
(getwidth): Don't assume termios.h defines TIOCGWINSZ,
as it doesn't on some older hosts.
Problem reported by Thorsten Hirsch in:
http://lists.gnu.org/archive/html/bug-tar/2014-04/msg00011.html
* src/unlink.c (flush_deferred_unlinks):
Do not attempt to find the parent of "." when "." is
at the top level.
* tests/remfiles10.at: New file.
* tests/Makefile.am (TESTSUITE_AT):
* tests/testsuite.at: Add it.
Based on patch from Pavel Raiskup <praiskup@redhat.com>.
* gnulib.modules: Add new modules.
* src/buffer.c (_open_archive): Refuse to read archive from a tty.
* tests/Makefile.am (TESTSUITE_AT): Add iotty.at
(check_PROGRAMS): New program ttyemu
* tests/testsuite.at: Include iotty.at
* tests/iotty.at: New file.
* tests/ttyemu.c: New file.
When --acls option is on (regardless of tarball contents or
tarball format), we should explicitly set OR delete default ACLs
for extracted directories. Prior to this update, we always
created arbitrary default ACLs based standard file permissions.
* configure.ac (with_posix_acls): Check also for acl_free and
acl_delete_def_file to mark IEEE 1003.1e ACLs as supported.
* src/xattrs.c (acl_delete_def_file_at): New function.
(xattrs__acls_set): Do not treat acls_option at all; Delete
default ACLs if appropriate.

Options --xattrs-include=MASK and --xattrs-exclude=MASK now turn

Fix also bug in printing in xattrs.c - don't print when option is
negative.
* src/tar.c (set_xattr_option): New static function.

See https://savannah.gnu.org/patch/index.php?8252. Patch provided

* acinclude.m4 (TAR_HEADERS_ATTR_XATTR_H): Look for <sys/xattr.h>
first and then for <attr/xattr.h>. Link against libattr.so if
needed.

on which one is detected.
