of eventually unconsumed options during archive creation.
Report unconsumed options, if any.

* configure.ac: Version 1.29.90
* doc/tar.texi: Document the changes.
The auxiliary utility ttyemu proved to be unreliable. Given existing
differences between pty implementations and termios ioctls on various
platforms, writing it in a portable way requires effort disproportional
to its actual purpose.
* configure.ac: Remove check for grantpt
* gnulib.modules: Remove posix_openpt, ptsname, and unlockpt
* tests/Makefile.am (TESTSUITE_AT): Remove iotty.at
(check_PROGRAMS): Remove ttyemu.
* tests/testsuite.at: Remove iotty.at
* tests/iotty.at: Remove.
* tests/ttyemu.c: Remove.
The --verbatim-files-from option disables option handling in
file lists. The --no-verbatim-files-from reverts its effect.
The --null option implies --verbatim-files-from. This restores
the documented behavior, broken by 26538c9b.
* src/common.h (verbatim_files_from_option): New global.
* src/names.c (name_elt): New member: file.verbatim
(name_add_file): Take 'verbatim' state as its third parameter.
(read_next_name): Don't call handle_option if file.verbatim
is set.
* src/tar.c: New options --verbatim-files-from and
--no-verbatim-files-from.
* doc/tar.texi: Document --verbatim-files-from and
--no-verbatim-files-from options.
* NEWS: Update.
* configure.ac: Version 1.28.90
* tests/T-null2.at: New testcase.
* tests/Makefile.am: Update.
* tests/testsuite.at: Update.
* 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.
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.

<http://lists.gnu.org/archive/html/bug-tar/2013-04/msg00009.html>.
* configure.ac (AM_GNU_GETTEXT_VERSION): Increase from 0.16 to 0.18.2.
README-alpha says that we do not make any efforts to accommodate
older versions of Gettext.
* configure.ac (gl_GCC_VERSION_IFELSE): New macro, from coreutils.
(gl_gcc_warnings): By default, disable warnings for GCC versions
before 4.6. This works around a failure when building from git on
Ubuntu 10, reported privately by Nathan Stratton Treadway.
This has a similar meaning as in other GNU applications
such as coreutils and Emacs.
* NEWS: Document it.
* .gitignore: Remove redundant build-aux.
Remove gnu, since gnu/Makefile.am is now in git.
Add gnu/.gitignore, gnu/charset.alias, gnu/*.h, gnu/*/ to cover
autogenerated files.
* bootstrap.conf (gnulib_mk): Remove.
* configure.ac: Add support for --enable-gcc-warnings,
taken from coreutils and simplified.
* gnu/Makefile.am: New file. Formerly this was autogenerated,
but the autogenerated file has been renamed to gnulib.mk,
its usual name when bootstrapping from gnulib.
This way, AM_CFLAGS can incorporate warning options.
* gnulib.modules: Add manywarnings.
* lib/Makefile.am, src/Makefile.am (AM_CFLAGS): New macro,
incorporating warning options.

literals in a char * context.
* src/xattrs.c, src/xattrs.h (xattrs_clear_setup):
Declare parameters as (void), not ().
* src/xheader.c (xheader_format_name): Initialize pptr to null,
to pacify GCC. Remove unnecessary test of nptr versus null.
* configure.ac: Avoid linking against -lacl when
--without-posix-acls is given.
* tests/selacl01.at: Call restorecon
* tests/selnx01.at: Likewise.
* tests/testsuite.at (AT_SELINUX_UTILS_PREREQ): Likewise.

* tests/testsuite.at: Likewise.
* tests/acls01.at: New test.
* tests/acls02.at: New test.
This patch adds *xattr() stubs in case extended attribute support is
not present and implements the *attrat() family of functions. Based
on the patch by Pavel Raiskup <pavel@raiskup.cz> for gnulib.
* acinclude.m4 (TAR_HEADERS_ATTR_XATTR_H): New defun.
* configure.ac: Call TAR_HEADERS_ATTR_XATTR_H

* lib/xattr-at.h: New file.
The regression was introduced by 8f390db9. This patch implements additional
option --skip-old-files, which silently skips members which would cause
writing over existing files, and restores --keep-old-files to its traditional
behavior.
* NEWS: Update.
* configure.ac: Update.
* doc/tar.texi: Document the changes.
* src/common.h (SKIP_OLD_FILES): New old_files mode.
* src/extract.c (maybe_recoverable): Restore KEEP_OLD_FILES behavior.
Handle SKIP_OLD_FILES.
* src/tar.c: New option --skip-old-files.
* tests/extrac18.at: New file.
* tests/extrac19.at: New file.
* tests/Makefile.am: Add new test cases.
* tests/testsuite.at: Likewise.
* configure.ac, NEWS: Version 1.24
* bootstrap: Restore tar-specific code lost during last
sync from gnulib (241b72ffad).
* src/misc.c (chdir_do): Remove unused automatic variable.
This patch fixes a race condition in the --atime-preserve=replace
option, which might cause tar to improperly follow a symbolic link.
It also drops the use of the _FIOSATIME ioctl of Solaris 2.x
and later, which loses resolution on time stamps. Modern Solaris
systems support full-resolution time stamps in the kernel, and
it's not worth the hassle of testing this call, useful only in
no-longer-supported Solaris variants.
Also, it undoes a change I recently introduced to the --compare
option, which caused it to not follow symbolic links unless the
--dereference option was also used. Quite possibly this change is
a good idea, but the old behavior was documented and the change
should not have been installed casually.
* configure.ac: Don't check for stropts.h and sys/filio.h.
* gnulib.modules: Add futimens, utimensat. Remove futimens.
* src/common.h (fd_utimensat): New decl.
* src/compare.c (diff_file, diff_multivol):
Don't use open_read_flags: those are for --create only.
* src/create.c (dump_file0): Adjust to set_file_atime changes.
Pass fstatat_flags to set_file_atime, so that symbolic links are
not followed inadvertantly.
* src/extract.c: Don't include utimens.h.
(set_stat): Use fd_utimensat ant UTIME_NOW rather than fdutimens.
* src/misc.c: Don't include utimens.h, stropts.h, sys/filio.h.
(fd_utimensat): New function.
(set_file_atime): Use it. New arg atflag, controlling symlink
handling. All callers changed.
* configure.ac: Check for fchmod and fchown. Don't check for utimes.
* src/extract.c (fdchmod, fdchown, fdstat): New functions.
(set_mode, set_stat): New arg FD. All callers changed.
This avoids some race conditions between closing a regular file
and setting its metadata, and it's a bit faster.
* src/system.c (stat_to_env): Pass information about the current
volume in variables TAR_ARCHIVE, TAR_VOLUME, TAR_BLOCKING_FACTOR,
TAR_FORMAT.
* doc/tar.texi: Document new environment variables.
* NEWS: Likewise.
* configure.ac: Version number 1.22.91.
This adds --with-gzip, --with-bzip2 etc. switches to the configure, so that
one can do, e.g. ./configure --with-bzip2=lbzip2 and have lbzip2 executed
whenever user calls `tar --bzip2'.
* acinclude.m4: New file.
* configure.ac: Add TAR_COMPR_PROGRAM invocations for
the supported compressors.
* src/buffer.c (magic): Use *_COMPRESSOR defines instead
of hardcoded program names.
* src/suffix.c (compression_suffixes): Likewise.
* Makefile.am (INCLUDES): Add ../lib, for rmt-command.h
* src/buffer.c (short_read): Report the actual record size
only if the archive descriptor refers to a device.
* tests/pipe.at, tests/shortrec.at,
tests/sparsemvp.at: Reflect the above change.
* NEWS, configure.ac: Version 1.22.90
* doc/tar.texi: Document transformation scope flags.
* src/common.h (transform_symlinks_option): Remove in favor of
transformation scope flags.
(XFORM_REGFILE, XFORM_LINK, XFORM_SYMLINK, XFORM_ALL): New macros.
(transform_name, transform_member_name, transform_name_fp): Take
an additional argument, specifying scope flags.
* src/create.c: Reflect changes to transform_name.
* src/extract.c (extract_link, extract_symlink): Remove calls to
transform_member_name. It is done in read_header.
* src/list.c (decode_xform): Reflect change in data type of 2nd
argument.
(transform_member_name): 2nd arg is int.
(decode_header): Transform file name and link target names.
* src/tar.c: Remove --transform-symlinks.
* src/transform.c (struct transform): New member `flags'.
(transform_flags): New variable.
(parse_transform_expr): Parse transformation scope flags. Allow to
set global flags using `flags=' syntax.
(_transform_name_to_obstack, transform_name_fp)
(transform_name): Take an additional argument, specifying scope
flags.
* doc/tar.texi: Document -J, --no-auto-compress, etc.
* src/buffer.c (ct_tar): New constant.
(magic): Add lzop support. Proposed by Kevin Day
<thekevinday@gmail.com>.
(check_compressed_archive): Do not use autodetect if the
compression program was specified explicitly.
Fall back to analyzing archive name, if the autodetection fails.
* src/suffix.c: Add .lzo
* src/tar.c: New options --lzop and --no-auto-compress.
New short option -J (alias for --lzma).
