gnu tar 源码包。 tar 软件是 Unix 系统下的一个打包软件

	the new argp method instead.

2006-09-12  Sergey Poznyakoff  <[e-mail]>

	* README: Fix a typo

2006-09-08  Paul Eggert  <[e-mail]>

	Adjust to latest gnulib.
	* lib/.cvsignore: Add at-func.c, configmake.h, fchmodat.c,
	fcntl.h, fcntl_.h, inttypes_.h, lstat.c, lstat.h.
	* tests/testsuite.at (AT_TAR_MKHIER): Use install-sh -d
	rather than the no-longer-included mkinstalldirs.

2006-09-08  Sergey Poznyakoff  <[e-mail]>

	* src/incremen.c (try_purge_directory): Initialize struct st.  Fix
	condition for selecting candidates for removal.
	* README-alpha: List texinfo among build prerequisites for the CVS
	version.

	* bootstrap (intl_files_to_remove): Do not remove m4/inttypes-h.m4
	and m4/inttypes-pri.m4

2006-08-11  Paul Eggert  <[e-mail]>

	* bootstrap: Set XGETTEXT_OPTIONS to flag our printf-format functions,
	so that translators are warned about strings that are formats but
	don't look like formats.  This might help prevent core dumps.
	* configure.ac (AM_GNU_GETTEXT): Upgrade to need-formatstring-macros.
	Suggested by Eric Blake to avoid problems like
	<http://lists.gnu.org/archive/html/bug-coreutils/2006-07/msg00087.html>.
	(AM_GNU_GETTEXT_VERSION): Upgrade from 0.12.1 to 0.15.  The gettext
	manual says we should use the version number normally expected of
	maintainers, neither more nor less.

	* bootstrap (get_translations):
	Don't exclude ky.po; it is working again.

2006-08-09  Paul Eggert  <[e-mail]>

	* bootstrap (get_translations):
	Don't exclude ja.po; it is working again.
	Don't remove all old .po files if we're merely updating one.
	* po/.cvsignore: Add Makevars.

2006-08-07  Paul Eggert  <[e-mail]>

	* src/tar.c: Work around limitation imposed by gettext 0.15
	by concatenating strings with "\v" after translation.
	(doc): Remove, splitting into:
	(doc0, doc1): New constants.
	(argp): Don't use doc; just initialize to NULL.
	(initialize_argp_doc): New function.
	(decode_options): Use it.

	* bootstrap: Redo po file retrieval to match Bison's method,
	since the translation project changed its index format.
	Don't use --assume-autoconf; it's now replaced
	by looking in configure.ac.
	(m4/codeset.m4, m4/intdiv.m4, m4/inttypes-pri.m4, m4/isc-posix.m4):
	(m4/lcmessage.m4, m4/onceonly_2_57.m4, m4/gettext.m4, m4/glibc21.m4):
	(m4/inttypes_h.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4):
	(m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4):
	Don't rename to ..._gl.m4, as this is no longer needed.
	(m4/geteext.m4): Patch to remove the need for intl/*.
	Use autopoint manually, then remove the intl files,
	then undo changes to gnulib files that autoreconf made,
	and then run aclocal/autoconf/autoheader/automake.
	This makes our bootstrap procedure closer to Bison's.
	(po/Makevars): Generate automatically.
	* configure.ac (AC_PREREQ): Update from 2.59 to 2.60.
	(gl_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Remove.
	* gnulib.modules: Add inttypes, stdint.
	* lib/.cvsignore: Add close-stream.c, close-stream.h,
	stdint.h, stdint_.h.
	* po/Makefile: Remove; now automatically generated.

	* src/incremen.c (read_incr_db_01): Check input strings more
	carefully.  Do not pass arbitrary char values to isspace, as
	this has undefined behavior.  Likewise for assigning arbitrary
	uintmax_t values to other types.
	(read_negative_num, read_unsigned_num, read_timespec):
	New functions, to check input values a bit more carefuly.
	(read_num): Use read_unsigned_num.  New arg MAX_VAL;
	all callers changed.
	(read_incr_db_2): Use these new functions.
	Use a consistent diagnostic for unexpected EOF.
	(read_directory_file): Do not assign arbitrary uintmax_t value
	to int.
	(read_timespec, write_directory_file_entry, write_directory_file):
	Handle negative time_t values correctly.  We don't bother to do
	this with pre-2 formats, since presumably the time stamps were
	output incorrectly.

	* src/tar.c (doc): Don't use \v in an argument to gettext;
	gettext 0.15 rejects this.

2006-07-24  Sergey Poznyakoff  <[e-mail]>

	* src/tar.c (decode_options): Do not require -L with -M -Hpax.
	It could be needed in future, but currently it is not.
	* src/create.c (to_chars_subst): Update comment regarding OLDGNU
	vs. GNU format differences.
	(mode_to_chars): Treat OLDGNU_FORMAT same as GNU_FORMAT. Fixes bug
	reported by TAMUKI Shoichi <[e-mail]>, which caused
	equivalent `tar cf ...' and `tar rf ...' commands to produce
	different archives.

	* tests/append02.at: New test case
	* tests/Makefile.am, tests/testsuite.at: Add append02.at

2006-07-20  Paul Eggert  <[e-mail]>

	* bootstrap: Adjust to today's change to gnulib-tool by invoking
	it with --assume-autoconf='latest-stable'.

2006-07-16  Paul Eggert  <[e-mail]>

	Adjust to recent gnulib changes.
	* lib/.cvsignore: Remove atexit.c, exit.c, getndelim2.c, getndelim2.h,
	pathmax.h, paxconvert.c, paxerror.h, xstrdup.c.
	Add inttypes.h, mktime.c, wcwidth.h, xstrndup.c, xstrndup.h.
	* src/create.c (start_header): Adjust to API change to mode_adjust.
