changelog

实战Linux编程的原代码,希望对学驱动的人能有所帮助

	* po/POTFILES.in: Add lib/xmemcoll.c and src/sys2.h.

2002-01-21  Jim Meyering  <[e-mail]>

	* Makefile.maint (strftime-check): New rule.
	(local-check): Convert this target to a list.  Update uses.
	Mark them as .PHONY.
	(header-check): New rule.
	(local-check): Add header-check.

	* src/dirname.c: Don't include "xalloc.h", as system.h already
	does that via sys2.h.
	* src/expr.c: Likewise.

2002-01-19  Jim Meyering  <[e-mail]>

	* configure.ac: Remove code that set LIBOBJS in support of ansi2knr.
	The latest version of autoconf objected to it, and besides, I don't
	care too much about K&R support these days.

2002-01-14  Paul Eggert  <[e-mail]>

	* src/date.c, src/logname.c, src/pathchk.c: Comment fixes
	to bring us up to date with respect to POSIX 1003.1-2001.
	In particular, POSIX.2 is now obsolete.

2001-12-28  Jim Meyering  <[e-mail]>

	* configure.ac (ALL_LINGUAS): Add Catalan (ca).

2001-12-17  Jim Meyering  <[e-mail]>

	* Makefile.maint (real_dir): Remove unused variable.
	(url_dir_list): Don't set define it here, but...
	* Makefile.cfg (url_dir_list): ...define it here instead.
	(hosts, a_host, b_host): Remove now-unused variables.
	(alpha_subdir, a_url_dir, b_url_dir): Remove now-unused variables.

2001-12-15  Jim Meyering  <[e-mail]>

	* src/tty.c, src/uname.c, src/uptime.c, src/users.c, src/who.c,
	* src/whoami.c, src/yes.c (usage): Use fputs, not printf.
	Split --help output into smaller pieces.
	Use new macros, HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION
	instead of hard-coding --help and --version descriptions.

2001-12-08  Jim Meyering  <[e-mail]>

	* Makefile.cfg (wget_files): Remove ansi2knr.c, since it's
	no longer available at that location.

2001-11-25  Jim Meyering  <[e-mail]>

	* basename.c, dirname.c, expr.c, factor.c, hostname.c (usage):

	Indent --help and --version strings to start in the 7th column.

2001-11-17  Jim Meyering  <[e-mail]>

	* configure.ac: Replace use of the one-arg form of AC_INIT
	with a use of the 3-arg form and a use of AC_CONFIG_SRCDIR.

2001-11-11  Jim Meyering  <[e-mail]>

	* src/Makefile.am (printf_LDADD): Reflect spelling change:
	s/POW_LIBM/POW_LIB/.
	(sleep_LDADD): Likewise.

2001-11-10  Jim Meyering  <[e-mail]>

	arguments.

2001-09-28  Jim Meyering  <[e-mail]>

	rather than the two-`.' config.h.in.

2001-09-26  Jim Meyering  <[e-mail]>

	* man/Makefile.am (common_dep): Define it, so we depend on configure.ac.

	* configure.ac: Renamed from configure.in.

2001-09-25  Jim Meyering  <[e-mail]>

	* src/Makefile.am:
	(factor_DEPENDENCIES, printf_DEPENDENCIES seq_DEPENDENCIES):
	(sleep_DEPENDENCIES uptime_DEPENDENCIES su_DEPENDENCIES):
	Remove unnecessary definitions.  They can cause trouble
	when @INTLLIBS@ expands to -lintl.

2001-09-23  Jim Meyering  <[e-mail]>

	* Makefile.am (SUBDIRS): When using newer gettext (in which
	intl/libintl.h is created by rules intl/Makefile)
	`intl' must precede `lib'.

2001-09-17  Jim Meyering  <[e-mail]>

	* src/printf.c (main): Change the `ignoring excess arguments' diagnostic
	to list the first one we're ignoring.  Suggestion from Karl Berry.

2001-09-16  Jim Meyering  <[e-mail]>

	* src/stty.c (usage): Prefix each line with a space, so that
	help2man produces a better stty.1 man page.
	From Colin Watson, via Michael Stone.  http://bugs.debian.org/95816

	* src/test.c (usage): Describe -h option.
	From Colin Watson, via Michael Stone.  http://bugs.debian.org/99272

	* man/pwd.x: Add note to help people understand that this documentation
	may not refer to the (shell built-in) command they're running.
	* man/echo.x: Likewise.
	* man/printf.x: Likewise.
	From Michael Stone.

	* Makefile.am (AUTOMAKE_OPTIONS): Require automake-1.5.

	* man/Makefile.am: Revamp this file, as for fileutils.

2001-09-11  Jim Meyering  <[e-mail]>

	* configure.in: Move HOST_OPERATING_SYSTEM code from this file
	into a new macro defined in m4/host-os.m4.

2001-09-09  Jim Meyering  <[e-mail]>

	* src/test.c (binary_operator): Correct typo in diagnostic.
	From Jochen Hein.

2001-09-03  Paul Eggert  <[e-mail]>

	* NEWS: New 'uname' options -i or --hardware-platform,
	and -o or --operating-system.
	'uname -a' now outputs -i and -o information at the end.
	New uname option --kernel-version is an alias for -v.
	Uname option --release has been renamed to --kernel-release,
	and --sysname has been renamed to --kernel-name;
	the old options will work for a while, but are no longer documented.

	* configure.in (HOST_OPERATING_SYSTEM): New macro; set it
	from $host_os with a translation table and other heuristics.

	* src/uname.c: Correct copyright notice as per latest coding standards.
	Remove list of options in comment, which wasn't
	worth maintaining separately from usage().

	(print_element): Move definition up, avoiding the need for
	declaration and allowing inlining on some platforms.
	Keep track of whether something has been printed; this is more
	natural than modifying `toprint'.

	(PRINT_KERNEL_NAME): Renamed from PRINT_SYSNAME.
	(PRINT_KERNEL_RELEASE): Renamed from PRINT_RELEASE.
	(PRINT_KERNEL_VERSION): Renamed from PRINT_VERSION.
	(PRINT_HARDWARE_PLATFORM, PRINT_OPERATING_SYSTEM): New macros.
	(toprint): Remove global var; now local in `main'.
	(long_options, usage, main): Implement changes described in NEWS.
	Reorder options to reflect output order.
	(main): Use buffers one byte longer, for compatibility with Solaris 8.
	Output newline at end.  -a sets `toprint' to -1 now; this is simpler.
	Do not bother invoking system calls like uname if the resulting
	information does not need to be printed.
	Do not fail if sysinfo fails; just print "unknown".

2001-08-30  Paul Eggert  <[e-mail]>

	* src/tee.c (full_write): Remove decl; not needed.

2001-06-19  Paul Eggert  <[e-mail]>

	* NEWS: expr now uses LC_COLLATE for string comparison, as per POSIX.
	* src/expr.c (nextarg): Use strcoll, not strcmp.

2001-08-24  Jim Meyering  <[e-mail]>

	* src/pinky.c (main): Fail if -l is specified with no username.

	* src/pinky.c (usage): Clarify description of -l.  From Clark Morgan.

2001-06-21  Paul Eggert  <[e-mail]>

	* NEWS: 'expr' now requires '+' rather than 'quote' to quote tokens.

	* src/expr.c (posixly_correct): Remove; no longer needed.
	(main): Do not worry about POSIXLY_CORRECT, as it's OK for
	expr to have options (so long as they do not begin with digits).
	(eval6, usage): Use "+" rather than "quote" to quote tokens.

2001-08-19  Jim Meyering  <[e-mail]>

	* src/Makefile.am (bin_PROGRAMS): Add kill.
	* src/kill.c: New program.  Written by Marcus Brinkmann.

2001-08-19  Jim Meyering  <[e-mail]>

	* po/POTFILES.in: Add src/kill.c

2001-06-21  Paul Eggert  <[e-mail]>

	* src/expr.c (nextarg): Advance ARGS by one if the next token matches.
	All callers changed.

2001-06-21  Paul Eggert  <[e-mail]>

	* src/expr.c (isstring): Remove.
	(eval2): Do comparisons as strings first, before trying to convert to
	integer.  This avoids loss of information and wrong result, e.g. for
	"expr '00' '<' '0!'", where you don't want to convert '00' to '0'.

2001-08-18  Jim Meyering  <[e-mail]>

	* tests/expr/basic (00): New test for the above.

2001-06-21  Paul Eggert  <[e-mail]>

	* src/expr.c: Code cleanup to avoid tricky macros and
	old-style function declarations.

	(cmpf, less_than, less_equal, equal, not_equal, greater_equal,
	greater_than, arithf, arithdivf, plus, minus, multiply, divide, mod):
	Remove.

	(eval4, eval3, eval2): Rewrite to avoid the need for the above macros
	and functions.

2001-08-18  Jim Meyering  <[e-mail]>

	* src/test.c (binary_operator): Move declarations of lt,rt `down'
	into the scopes where they're actually used.
	(unary_operator): Likewise for `fd'.

2001-06-20  Paul Eggert  <[e-mail]>

	* src/test.c (isint, binary_operator, unary_operator):
	Use intmax_t for argument integers, not long.
	(age_of, binary_operator): Use time_t for times, not long.
	(unary_operator): If N is out of int range, -t N now returns false.

2001-06-20  Paul Eggert  <[e-mail]>

	* src/expr.c (main): Handle a leading "--" option as POSIX requires.

2001-08-18  Jim Meyering  <[e-mail]>

	* tests/expr/basic: Add a test for the above.

2001-06-20  Paul Eggert  <[e-mail]>

	* src/expr.c (toarith): Don't accept plain "-" as a valid integer.

2001-06-20  Paul Eggert  <[e-mail]>

	Modify 'expr' so that it uses intmax_t, not int, to calculate
	the value of integer expressions.

	* src/expr.c (struct valinfo.i): Now intmax_t, not int.
	(docolon, int_value, str_value, isstring, nextarg, toarith,
	freev, tostring, trace): Remove unnecessary forward decls.
	(int_value, printv, tostring, toarith, arithf, arithdivf, docolon,
	eval6, eval4, eval3): Do integer arithmetic using intmax_t, not int.
	(docolon): Don't assume size_t fits in int.

2001-08-18  Jim Meyering  <[e-mail]>

	* tests/expr/basic: New test for the above.
	* tests/expr/Makefile.am: New file.
	* tests/expr: New directory.
	* tests/Makefile.am (SUBDIRS): Add expr.
	* configure.in (AC_OUTPUT): Add tests/expr/Makefile.

2001-08-18  Jim Meyering  <[e-mail]>

	Revert part of last change and solve the problem a better way.
	* src/date.c (show_date) [--rfc-822]: Set LC_ALL=C just before
	calling strftime and restore it just afterwards.
	Suggestion from Ulrich Drepper.

2001-08-18  H. Peter Anvin  <[e-mail]>

	* src/date.c (show_date) [--rfc-822]: Don't space-pad the day of
	the month.
	Set only LC_TYPE to the "C" locale.  Setting LC_ALL is overkill,
	and would have unwanted side effects if there is an error message.

2001-08-16  Jim Meyering  <[e-mail]>

	* src/date.c (main): When there are too many non-option arguments,
	include the first offending argument in the diagnostic.
	Suggestion from Karl Berry.

2001-08-14  Jim Meyering  <[e-mail]>

	* src/Makefile.am (INCLUDES): Add -I../lib so sys2.h can include
	the new, generated file, unlocked-io.h.

	* tests/Makefile.am (TESTS_ENVIRONMENT): Remove first definition
	of this variable, and move its RHS into the RHS of the second.
	Thanks, automake!

	* src/su.c (xputenv): Remove parameter's const qualifier.

	* src/dirname.c, src/env.c, src/id.c, src/pathchk.c, src/pinky.c,
	* src/printenv.c, src/sleep.c, src/tee.c, src/test.c, src/uptime.c,
	* src/users.c, src/who.c: (AUTHORS): Mark string for translation,
	since it contains the English word `and'.

2001-08-12  Jim Meyering  <[e-mail]>

	* src/pathchk.c (PATH_MAX_FOR): Use pathconf via wrapper.
	(NAME_MAX_FOR): Likewise.
	Guard the above pathconf-using definitions with `#if HAVE_PATHCONF'
	rather than with `#ifdef _POSIX_VERSION'.
	(pathconf_wrapper): New function.
	(validate_path): Declare length variables to be `long', not `int'.
	Adjust corresponding printf-style specs to use %ld.
	Reported by Neal H Walfield.

2001-08-07  Jim Meyering  <[e-mail]>

	* src/printf.c (cfcc_msg): Remove now-inaccurate part of comment.
	From Bruno Haible.

	(PIDSTR_DECL_AND_INIT): Define.

2001-06-05  Jim Meyering  <[e-mail]>

	* configure.in (ALL_LINGUAS): Add Turkish (tr).

2001-05-27  Jim Meyering  <[e-mail]>

	* src/dirname.c (main): Add `const' to declaration of local, `result'.

2001-04-01  Jim Meyering  <[e-mail]>

	Add options to make `who' more POSIX compliant.
	* who.c: Accept new options: --all (-a), --boot (-b), --dead (-d),
	--login, --process (-p), --runlevel (-r), --short (-s), --time (-t),
	--users (-u).
	The -u option now produces POSIX-specified results and is the same as
	the long option `--users'.  --idle is no longer the same as -u.
	(time_string, print_line, print_boottime, print_deadprocs, print_login,
	print_initspawn, print_clockchange, print_runlevel): New functions.
	(print_user): Renamed from print_entry and reworked.
	(search_entries): Remove function.
	(who_am_i): Likewise.
	(usage): Describe new options.
	(main): Handle new options.
	Mostly from Michael Stone.

2001-05-11  Paul Eggert  <[e-mail]>

	dirname code cleanup.  base_name now behaves more compatibly
	with POSIX basename when given file names that have trailing
	slashes, and similarly for dir_name.  Add new primitives
	base_len and dir_len.  Put the directory-name-related decls
	into dirname.h.

	* basename.c: Include "dirname.h".
	(base_name, strip_trailing_slashes): Remove decls; now in dirname.h.
	(main): Use base_len instead of strip_trailing_slashes to strip
	trailing slashes.

	now in dirname.h.
	(main): Use dir_len rather than dir_name_r.
