制作2.6内核的CLFS时 使用的diffutils-2.8.7.tar.gz包

2004-04-13  Paul Eggert  <[e-mail]>

	* NEWS, configure.ac (AC_INIT): Version 2.8.7.
	* configure.ac (AM_GNU_GETTEXT_VERSION): Add.
	(XGETTEXT): Restore from pre-2004-04-12 version.  This fixes
	a bug that lost many msgids in doc/diffutils.pot.
	* bootstrap: New file.
	* exgettext: Don't generate a temporary file, as this runs afoul
	of "make distcheck" which operates with read-only directories.
	* Makefile.am (EXTRA_DIST): Add bootstrap.
	Remove config/config.rpath as it is deduced automatically these days.

2004-04-12  Paul Eggert  <[e-mail]>

	* NEWS, configure.ac (AC_INIT): Version 2.8.6.

	* NEWS: Add news for 2.8.4, 2.8.6.

	* README: Move copyright notice to end.  Defer to "configure
	--help" for special "configure" options.  Suggest latest libiconv.
	Update version numbers of Autoconf etc. to current.

	* configure.ac: Quote various arguments better.
	(AC_CONFIG_MACRO_DIR): Add call, specifying "m4".
	(AC_CONFIG_HEADER): Replaces AM_CONFIG_HEADER.
	(gl_USE_SYSTEM_EXTENSIONS): Replaces AC_GNU_SOURCE.
	(AC_ISC_POSIX): Remove; nobody ports to ancient ISC any more.
	(AC_PROG_CPP, AC_PROG_INSTALL, AC_C_INLINE,
	AC_HEADER_STDBOOL, AC_HEADER_STDC, AM_GNU_GETTEXT, XGETTEXT,
	AC_HEADER_STAT, AC_FUNC_VPRINTF, jm_FUNC_GLIBC_UNLOCKED_IO,
	jm_FUNC_GNU_STRFTIME, jm_FUNC_MALLOC, jm_FUNC_REALLOC,
	jm_PREREQ_C_STACK, jm_PREREQ_ERROR, jm_PREREQ_HARD_LOCALE,
	jm_PREREQ_QUOTEARG, jm_PREREQ_REGEX, AC_FUNC_FNMATCH_GNU, jm_AC_DOS):
	Remove; not needed here, as our files don't use them directly
	or we rely on gnulib modules.
	(AC_C_CONST): Remove; we assume C89 now.
	(AC_CHECK_HEADERS): Remove libintl.h, limits.h, stdlib.h, string.h,
	time.h.
	(AC_CHECK_TYPE): Remove ptrdiff_t, ssize_t.
	(AC_CHECK_FUNCS): Remove diraccess, strchr, strerror, tmpnam).
	(AC_REPLACE_FUNCS): Remove memchr, mkstemp, strcasecmp.

	(AC_CONFIG_COMMANDS): Remove.
	
	* doc/diff.texi (dircategory): Change to "Text creation and
	manipulation" from "GNU packages".
	(Translations): New node.
	(Overview): Improve quality of algorithm citations.
	(Binary): -q doesn't exactly cause diff to assume files are binary.
	(Normal): Place after Side by Side, since it's less important.
	(Detailed Context, Detailed Unified, Detailed ed,
	Detailed if-then-else, diff3 Hunks, Detailed diff3 Normal):
	Place at end of menu.
	(Detailed Unified): Mention that fractional timestamps are
	omitted on hosts that don't support them.
	Mention what happens when hunks contain just one line.
	(Line Group Formats, Reject Names): Fix duplicate-word typos.
	(Comparing Directories): Trailing white space and empty lines are
	ignored in the -X file.
	(diff Options): Add --strip-trailing-cr.
	(Projects): gnu -> [e-mail].

	* lib/Makefile.am (SUBDIRS): Remove.
	(EXTRA_DIST, noinst_HEADERS): Remove most entries.
	(libdiffutils_a_SOURCES): Now just lib_SOURCES.
	(lib_SOURCES): New macro.
	(DISTCLEANFILES, MOSTLYCLEANFILES): Set to empty now.
	(gnulib.mk): Include: this does most of the work eliminated
	by the above changes.

	* lib/inttostr.c (inttostr): Protect i < 0 by compile-time
	test intended to suppress compiler warnings.
	* lib/inttostr.h: Include limits.h unilaterally.
	(CHAR_BIT): Remove.
	(PARAMS): Remove; all uses changed.
	* lib/setmode.c (__attribute__): New macro.
	(set_binary_mode): Define only if HAVE_SETMODE_DOS.
	Otherwise define a dummy static char, as C89 requires
	that we define something.
	* lib/setmode.h (set_binary_mode): Return true, not 1.

	* src/analyze.c, src/context.c, src/diff.c, src/io.c, src/util.c:
	Do not include regex.h, as diff.h does this now.

	* src/cmp.c: Sort includes.  Include <exit.h>, <unlocked-io.h>.
	(specify_comparison_type): Don't report an error if the comparison
	type has already been specified the same way as this one.

	* src/cmp.c (usage): Mention exit status.
	* src/diff.c (option_help_msgid): Likewise.
	* src/diff3.c (usage): Likewise.
	* src/sdiff.c (usage): Likewise.

	* src/cmp.c (main): Adjust to latest gnulib c_stack_action
	calling conventions.
	* src/diff.c (main): Likewise.
	* src/diff3.c (main): Likewise.
	* src/sdiff.c (main): Likewise.

	* src/cmp.c (main): Adjust to latest version_etc calling conventions.
	* src/diff.c (main): Likewise.
	* src/diff3.c (main): Likewise.
	* src/sdiff.c (main): Likewise.

	* src/diff.c: Include <exit.h>.
	(binary): Define to true if not declared.
	(longopts): Set tabsize flag to 1.
	(main): Don't output nanoseconds if platform lacks them.
	Don't treat files as binary if !binary.
	(set_mtime_to_now): Use 0, not NULL.
	(compare_files): Mark files as nonexistent if it looks like
	'patch' created inaccessible regular empty files to denote
	nonexistent backups.  Don't compare such files.
	Clear st_* members of status of	nonexistent file.
	Remove now-unnecessary tests.

	* src/diff.h: Include regex.h, unlocked-io.h.
	(struct file_data.changed): Now char *, not bool *, to save
	space on hosts where bool takes more space than char.
	All uses changed.

	* src/diff3.c: Include unlocked-io.h.
	(strip_trailing_cr): New var.
	(STRIP_TRAILING_CR_OPTION): New enum.
	(longopts, main, option_help_msgid, read_diff):
	Add --strip-trailing-cr support.
	(read_diff): Exit with status 126 (not 127) if errno != ENOENT
	after failed execvp in child.  Report this in parent.

	* src/dir.c: Include <strcase.h>.
	(failed_locale_specific_sorting): Renamed from failed_strcoll.
	All uses changed.
	(compare_names): Don't invoke strcasecmp first thing when
	ignore_file_name_case; if locale_specific_sorting, we should
	just use that.

	* src/ifdef.c (next_line): Remove; replace with...
	(next_line0, next_line1): New vars.
	(print_ifdef_script, print_ifdef_hunk):
	Use them to fix line-number computation bug.

	* src/io.c (find_and_hash_each_line): Don't convert char *
	to unsigned char *; just leave pointers as char *.  This
	lessens the number of potentially-dangerous casts.
	* src/util.c (lines_differ): Likewise.

	* src/sdiff.c: Include <unlocked-io.h>, <exit.h>.
	(check_child_status): Renamed from ck_editor_status, and
	accept a new arg MAX_OK_STATUS.  All callers changed.
	Handle status 126/127 as per POSIX.
	(edit): Likewise.
	(main): Likewise.  Fix getopt typo: -E wasn't supported.

	* src/system.h (S_IRWXU, S_IRWXG, S_IRWXO): Define if not defined.
	(S_IXUSR, S_IXGRP, S_IXOTH): Remove.
	Include <time.h> unconditionally, since we can assume C89 now.
	Likewise for <stdlib.h>, <string.h>.
	(getenv, EXIT_SUCCESS, EXIT_FAILURE, SSIZE_MAX, strchr, strrchr,
	memcmp, memcpy): Remove decl; no longer needed.
	(strcasecoll, strcasecmp): Define if not built in.
	(CTYPE_DOMAIN, ISPRINT, ISSPACE, TOLOWER, _tolower, errno): Remove;
	we now assume C89 or better.  All uses changed.
	Include <stdbool.h> unconditionally now, since gnulib supports it
	if the C compiler doesn't.  All boolean uses of 0 and 1 now
	changed to false and true.
	(lin_is_printable_as_long_int): Renamed from lin_is_printable_as_long.

	* src/util.c (begin_output): Fix bug: 0 wasn't cast to char * arg,
	which led to undefined behavior on 64-bit hosts.
	Use more-standard test for exit status 126 versus 127.
	(finish_output): Likewise.
	(analyze_hunk): Do not cast bool to int.

2004-03-15  Paul Eggert  <[e-mail]>

	* src/cmp.c (main): Don't consider two files with the same name to
	be the same, if their initial skip values differ.  This fixes a
	bug reported by Hideki Iwamoto in
	<http://mail.gnu.org/archive/html/bug-gnu-utils/2004-03/msg00024.html>.

2004-03-11  Paul Eggert  <[e-mail]>

	* src/analyze.c (diag): Return void, not lin, since the return
	value wasn't needed.  All callers changed.
	(diag, diff_2_files):
	Use 'true' and 'false' instead of '1' and '0', when appropriate.
	(compareseq): Use lin const * local variables instead of lin *.
	Don't bother checking diag's return value.
	(shift_boundaries, build_reverse_script, build_script, diff_2_files):
	Use char arrays, not bool arrays, since
	sizeof (bool) might be greater than 1.

2004-02-09  Paul Eggert  <[e-mail]>

	* m4/setmode.m4 (AC_FUNC_SETMODE_DOS): AC_LIBOBJ(setmode) if
	we would return true.

2002-10-14  Paul Eggert  <[e-mail]>

	* src/Makefile.am (diff3.$(OBJEXT), diff.$(OBJEXT),
	sdiff.$(OBJEXT)): Rename from (misspelled) diff3.$(OBJECT),
	diff.$(OBJECT), sdiff.$(OBJECT).  Patch by Paul D. Smith in
	<http://mail.gnu.org/pipermail/bug-gnu-utils/2002-October/003251.html>.
	Bug reported by Chris Bainbridge.

2002-10-13  Paul Eggert  <[e-mail]>

	* src/Makefile.am (MOSTLYCLEANFILES): Add paths.ht.
	(paths.h): Send output to paths.ht first, and then rename to
	paths.h at the end.  This avoids problems if the disk is full.
	It also works around what appears to be a bug with GNU make -j
	(3.79.1); see <http://bugs.gentoo.org/show_bug.cgi?id=8934>.

	since one of the files may not be a binary file.
	Bug reported by Dan Jacobson.

2002-06-22  Paul Eggert  <[e-mail]>

	* lib/fnmatch.c, lib/fnmatch_loop.c (WIDE_CHAR_SUPPORT):
	New macro.  Use it uniformly instead of
