实战Linux编程的原代码,希望对学驱动的人能有所帮助

Sat Nov 05 08:35:25 1994  Jim Meyering  ([e-mail])

	* Version 1.12.

Fri Nov 04 06:01:00 1994  Jim Meyering  ([e-mail])

	* Version 1.11.

Wed Nov 02 18:52:20 1994  Jim Meyering  ([e-mail])

	* doc/Makefile.in (install): Remove test for existence of info
	file.  Simply change to $(srcdir) instead.

Wed Oct 26 23:40:07 1994  Jim Meyering  ([e-mail])

	* safe-xstat.hin [EINTR]: Always define safe_l?stat.
	Define it __static -- which is `static' for most includers,
	but `/* empty */' for safe-xstat.cin.
	* safe-xstat.cin: Define __static to nothing so we get public
	safe_l?stat functions in the library.

	* Makefile.in (All actions invoking $(MAKE) from within compound
	(e.g. `for') sh statements): Exit non-zero if the sub-make fails.
	Otherwise, the top-level make may exit successfully when it should
	fail.  From Jim Kingdon ([e-mail]).

Sun Oct 23 23:36:26 1994  Jim Meyering  ([e-mail])

	* safe-xstat.hin: Don't use a statement expression here.
	Use an inline function instead.
	* safe-xstat.cin: Don't duplicate the definition of safe_l?stat here.
	Get the definition from safe-xstat.hin.

Fri Oct 21 00:57:23 1994  Jim Meyering  ([e-mail])

	* man/Makefile.in: Fix typo that had su.1 being installed as
	`man/man1/.1'.  From Kjetil Torgrim Homme.

	* basename.c, dirname.c, expr.c, pathchk.c, sleep.c (main): Diagnose
	wrong number of argument -- usually too few -- instead of just
	referring the user to the --help option.  Reported by Karl Berry.

Mon Oct 17 23:55:41 1994  Jim Meyering  ([e-mail])

	* doc/Makefile.in (install): Install the info files from either
	the source directory or the object directory.
	From Ian Lance Taylor ([e-mail]).

Sun Oct 16 12:14:02 1994  Jim Meyering  ([e-mail])

	* lib/Makefile.in (distclean): Don't delete getdate.c and posixtm.c
	here since they are not distributed.
	(realclean): Delete them here instead.
	From Francois Pinard.

Mon Oct 10 21:44:42 1994  Jim Meyering  ([e-mail])

	* id.c (print_group_list, print_full_info): Use more precise
	feature tests.  Rather than assuming that a definition for
	NGROUPS_MAX implies the existence of the getgroups function,
	test for HAVE_GETGROUPS explicitly.
	* su.c (log_su): Likewise.  Similarly, check HAVE_INITGROUPS.
	Both from Kaveh Ghazi.  He reported that a Pyramid 9820 OSx 5.0d
	(Dual universe SVR3/BSD4.2) system had NGROUPS_MAX and syslog.h
	but not getgroups, initgroups or the syslog functions.

Fri Oct 07 19:42:35 1994  Jim Meyering  ([e-mail])

	* doc/Makefile.in (sh-utils.dvi): Depend on version.texi.
	* version.texi: Use RELEASEDATE, not RELEASE_DATE.
	* sh-utils.texi: Likewise.

	* configure.in: Test for crypt in -lcrypt for NetBSD.
	Reported by Greg Hudson ([e-mail]).

	* system.h: Don't define lstat.  safe-l?stat.h does that now.

Thu Oct 06 21:14:07 1994  Jim Meyering  ([e-mail])

	* src/Makefile.in (link_command): Remove $(CFLAGS).  Because
	the default value usually includes -g, Linux users were getting
	statically linked executables.  With this removal they'll get
	much smaller, dynamically linked ones by default.

	* lib/Makefile.in (safe-lstat.o): Depend on safe-stat.h, too.

Sun Oct 02 16:15:32 1994  Jim Meyering  ([e-mail])

	* src/Makefile.in: Don't use binprefix.  Use autoconf-2's
	@program_transform_name@ instead.
	* man/Makefile.in: Likewise for manprefix.

	* safe-xstat.hin [!S_ISLNK]: Include safe-stat.h and define
	SAFE_LSTAT and safe_lstat to their symlink-ignorant counterparts.
	* lib/Makefile.in (extract_lstat, extract_stat): Add sed rules to
	extract the new cpp directives into safe-lstat.h, but not into
	safe-stat.h.

Sat Oct 01 00:14:10 1994  Jim Meyering  ([e-mail])

	* system.h: Remove conditional definition of mode_t.
	configure takes care of this now.

	* configure.in: Add -l$lib (not $lib) to LIBS when checking
	for syslog.  From Kaveh Ghazi.

	* date.c (batch_convert): Use K&R style function definition.
	From Kaveh Ghazi.

	* date.c (main): When reading dates from a file with a +FORMAT-style
	user-specified format, don't print the leading `+'.  Franc,ois Pinard
	noticed this problem.
	Make an error message clearer.  From Franc,ois.

	* lib/Makefile.in (DISTFILES): Add getline.h.
	(SOURCES, OBJECTS): Add getline.c, getline.o.

	* safe-xstat.hin: Don't include <sys/types.h> or <sys/stat.h>.
	Otherwise, we'd lose when the includer has already included
	<sys/stat.h> on systems that aren't protected against multiple
	inclusion.  Add a note that those headers must be included before
	this one.  Don't include <config.h> either.
	* safe-xstat.cin: Include <sys/types.h> and <sys/stat.h> here instead.
	Include <config.h> here, too.
	Kaveh Ghazi reported this problem.

Fri Sep 30 22:40:21 1994  Jim Meyering  ([e-mail])

	* date.c (main): Accept new option: (-f) --file=datefile.
	(batch_convert): New function.  Suggested by Karl Berry.

	* date.c (main): Diagnose use of conflicting options.
	Revamp non-option argument processing.
	Detect write errors.

	* lib/*.c, src/*.c: Remove CONFIG_BROKETS conditional.
	* lib/Makefile.in src/Makefile.in: Don't define it.

	configure.in (AC_CHECK_FUNCS): Add getcwd.  From Kaveh Ghazi.

	* safe-xstat.c.in, safe-xstat.h.in: Rename to safe-xstat.cin and
	safe-xstat.hin so the names don't exceed the 14-character limit.
	Reported by Kaveh Ghazi.

Mon Sep 26 19:49:40 1994  Jim Meyering  ([e-mail])

	* configure.in: Don't use $su_cv_sys_tiocgwinsz_in_termios_h
	uninitialized.  From R. Bernstein <[e-mail]> and Kaveh Ghazi.
	(NICE_PRIORITY): Fix typo that caused omission from PROGS of nice
	and nohup on systems with nice but not setpriority.
	From Andreas Schwab.

Sat Sep 24 10:13:00 1994  Jim Meyering  ([e-mail])

	* Makefile.in (stamp-h.in): Create using echo, not date.
	Using the latter could easily lead to rcs/cvs merge conflicts.
	* configure.in (stamp-h): Ditto, though this is less important
	because stamp-h isn't distributed.

	* nice.c (main): Revamp option processing to detect options
	like `--7' manually and pass the rest off to getopt_long.
	(isinteger): Use ISDIGIT.
	Use parse_long_options.

	* system.h: Include <ctype.h> and add IS* macros.
	* expr.c: Don't include <ctype.h> or define IS* macros since
	system.h now does that.
	* printf.c: Ditto.

	* date.c (usage): Add description of numeric modifiers.

	* printf.c (print_formatted): Declare DIREC_LENGTH size_t, not int.
	(print_esc_string): Ditto for LENGTH.
	* dirname.c (main): Cast string literal to (char*).
	* stty.c (wrapf): Declare first argument const char *.
	* tee.c (main, tee): More const dcls and casting.
	* who.c (read_utmp): New variable: size to avoid type warnings.
	All of these eliminate compilation warnings reported by
	Franc,ois Pinard.

	* doc/Makefile.in (DISTFILES): Add version.texi because generating
	that file now depends on having a version of date that can handle
	formats like `+%Y %B'.
	(version.texi): Generate RELEASE_DATE, too.
	* sh-utils.texi: Use RELEASE_DATE instead of hard-coded date.

	* long-options.h: Prepend underscores to arg names in prototype
	to avoid warnings about shadowing.

	* src/Makefile.in: Add dependencies on long-options.h.

	* configure.in: Make having autoconf-1.120 a prerequisite.

	* sh-utils.texi [INFO-DIR-ENTRY]: Add an entry for each `invoking'
	node.  Regularize punctuation, indexing, and xrefs.
	From Franc,ois Pinard.

	* date.c (usage): Tweak the usage message a little.
	Add `const' to more dcls.

	* stty.c: Add `const' to more dcls.
	* su.c: Ditto.
	* who.c: Ditto.

	* tee.c (main): Use _POSIX_SOURCE, not _POSIX_VERSION.

Sat Sep 17 15:48:10 1994  Jim Meyering  ([e-mail])

	* (doc): New subdirectory with texinfo documentation.
	Thanks to Franc,ois Pinard and Karl Berry!
	Note however that it contains mainly the information from the
	`man' pages, so it is not good documentation.  But this way,
	at least we don't have to maintain the troff man pages anymore.

	* su.c: Test !HAVE_ENDGRENT and !HAVE_ENDPWENT rather than
	_POSIX_SOURCE to determine whether endgrent and endpwent should
	be defined away.
	* configure.in (AC_CHECK_FUNCS): Add endgrent and endpwent.

	* who.c: Test HAVE_SYS_PARAM_H rather than _POSIX_SOURCE
	to determine whether <sys/param.h> should be included.

	* date.c (main): Rewrite command-line argument handling code
	to give diagnostics for inconsistent options.

	* Makefile.in: Restructure dependencies using local-*
	and recursive-* targets to avoid evil double-colon rules.
	Although the actions assiciated with double-colon rules are
	run sequentially using GNU make-3.71, POSIX doesn't guarantee
	that behavior.	The next release may run them in parallel.
	Running the old rules in parallel would sometimes delete
	config.status before it was used in a subdirectory make.
	With several suggestions from Franc,ois Pinard.

Thu Sep 15 19:10:51 1994  Jim Meyering  ([e-mail])

	* stty.c [VWERSE && !VWERASE]: Define VWERASE for AIX-3.2.5.

Sat Sep 03 00:41:53 1994  Jim Meyering  ([e-mail])

	* lib/Makefile.in (safe-lstat.c, safe-lstat.h, safe-stat.c,
	safe-stat.h): Use $(srcdir) to find source files.
	(.c.o): Use -I. to get safe-lstat.h and safe-stat.h from the
	build directory.
	* src/Makefile.in (incl): Add -I../lib to get lib/safe-lstat.h and
	lib/safe-stat.h from the build directory.  From Michael I Bushnell
	<[e-mail]>.

	* Makefile.in: Remove rules to create installation directories.
	* {src,man}/Makefile.in: Put them here instead.

	* configure.in: Update to take advantage of autoconf 2.0 features.

Sat Aug 27 16:57:20 1994  Jim Meyering  ([e-mail])

	* system.h [BROKEN_STAT_MACROS]: Remove unnecessary #ifdef's.
	From Francois Pinard.

Thu Aug 18 11:44:48 1994  Jim Meyering  ([e-mail])

	* su.1: Explain why GNU doesn't support the `wheel group'.

Mon Aug 01 21:58:14 1994  Jim Meyering  ([e-mail])

	* date.c: Add --utc option.  It will supercede --uct.
	Change references to `universal coordinated time' to
	correct `coordinated universal time'.  From Harris Boldt Edelman
	<[e-mail]>.
	* date.1: Correct the documentation, too.

	* date.c (main, show_date): For -u, use gmtime instead of relying on
	localtime's ability to interpret the TZ enviroment variable.
	`date -u' failed (by reporting local time) on romp-ibm-bsd and PCs
	(DOS and OS/2) running emx 0.8h.  From R. Bernstein
	<[e-mail]>.

Sat Jul 30 07:52:27 1994  Jim Meyering  ([e-mail])

	* nohup.sh: Separate `nice -5' from COMMAND with `--' to ensure
	that COMMAND isn't interpreted as an option to nice.
	* groups.sh: Similarly, separate each name from `id -Gn' with `--'.
	Karl Berry pointed out that `groups --help user' gave confusing
	diagnostics.

Tue Jul 26 11:33:53 1994  Jim Meyering  ([e-mail])

	* su.c (main): Make copies of the password information we'll use
	so that log_su (through getlogin) doesn't clobber the static data.
	With suggestions from Francois Pinard.

	* system.h: Remove `|| defined(_POSIX_VERSION)' from test that
	decides whether to include <fcntl.h>.  From Francois Pinard.

Mon Jul 25 23:54:36 1994  Jim Meyering  ([e-mail])

	* pathchk.c (dir_ok): Use SAFE_STAT.
	* test.c (test_stat, binary_operator, unary_operator): Use SAFE_STAT
	and SAFE_LSTAT.
	* who.c (print_entry):  Use SAFE_STAT.

	* test.c (group_member): Remove function.  Use the one broken out
	into group-member.c instead.

Fri Jul 15 00:23:17 1994  Jim Meyering  ([e-mail])

	system.h: Remove unneeded decls of atof and atol.

Fri Jul 08 01:09:23 1994  Jim Meyering  ([e-mail])

	stty.c (main): Initialize max_col (used by wrapf) before calling
	display_speed.  Otherwise, `stty speed' output a spurious newline.
	From Andreas Schwab <[e-mail]>.

Sun Jul 03 08:44:00 1994  Jim Meyering  ([e-mail])

	* configure.in [AC_HAVE_HEADERS]: Add sys/param.h, for
	definition of HAVE_SYS_PARAM_H, now tested in pathmax.h.

	* configure.in [AC_WORDS_BIGENDIAN]: Add it.  This macro is
	required by memcmp.c on big-endian systems.  Its absence was
	diagnosed by Lars Duening ([e-mail]).

Sun Jun 19 00:18:06 1994  Jim Meyering  ([e-mail])

	* nice.c (main): Accept options like `--5' (equivalent to `-n -5')
	instead of letting getopt give an `unrecognized option' error.

	* long-options.c: Require another argument: version_string.
	Don't include "version.h" or "system.h".
	* basename.c, dirname.c, echo.c, expr.c, hostname.c, printf.c,
	pwd.c, stty.c, test.c, yes.c: Adjust callers of parse_long_options
	accordingly.

Thu Jun 02 14:11:31 1994  Jim Meyering  ([e-mail])

	* stty.c (main): Set max_col and current_col before running
	display_window_size.  Otherwise, `stty size' output a spurious
	newline.  From Bauke Jan Douma ([e-mail]).

Mon May 30 09:33:53 1994  Jim Meyering  ([e-mail])

	* test.c (test_syntax_error, beyond): Add __attribute__ ((noreturn))
	so gcc will know enough not to give warnings.
