+
+ * tests/install/basic-1: Test for the -d regression.
+
+2004-08-11 Dmitry V. Levin <ldv@altlinux.org>
+
+ * src/install.c (main): Fix -d regression introduced with
+ --target-directory support at 2004-06-25.
+
+2004-08-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/copy.c (copy_internal): When preserving links, unlink
+ a destination with link count greater than one. This is so
+ that commands like "cp -a" don't get confused when copying into
+ a destination that already contains many hard links. Problem
+ reported by Tim Waugh in:
+ http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00053.html
+
+2004-08-10 Paul Eggert <eggert@cs.ucla.edu>
+
+ Convert all files to UTF-8.
+ * tests/fmt/basic (8-bit-pfx): Use UTF-8, not Latin-1.
+ * tests/sort/Test.pm (16a): Likewise.
+ * tests/uniq/Test.pm (8): Likewise.
+ * tests/misc/printf-hex: Use ASCII, not Latin-1.
+
+ * NEWS: Document "sort -o -" and "tee -" POSIX-conformance fixes.
+ * src/shred.c (usage): "-" is an operand, not an option.
+ * src/sort.c (die, xfopen, mergefps, first_same_file, merge):
+ A null file arg means standard output.
+ (main): "-o -" means to write to a file named "-",
+ not to standard output.
+ * src/tee.c (usage, tee): "tee -" writes to standard output, not
+ to a file named "-".
+
+2004-08-10 Dmitry V. Levin <ldv@altlinux.org>
+
+ * src/install.c (change_timestamps): Fix int->bool conversion
+ bugs introduced on 2004-07-29.
+
+2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/shred.c (wipename): Work even if the directory is writeable
+ and not readable. Prefer write access, since this should work
+ better with fdatasync.
+
+ * src/csplit.c (xalloc_die): New function.
+ (main): Remove now-obsolete initialization of xalloc_fail_func.
+
+ * src/md5sum.c: Adjust to sha->sha1 renaming.
+
+2004-08-08 Dmitry V. Levin <ldv@altlinux.org>

+ (can_mode): Make variable local.
+
+2004-08-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/system.h (O_BINARY) [!O_BINARY && defined O_BINARY]:
+ Do not define, to avoid annoying compiler messages on QNX 6.3.
+ Problem reported by Johan in:
+ http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00050.html
+
+2004-08-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/system.h (PRIdMAX, PRIoMAX, PRIuMAX, PRIxMAX):
+ Define to a concatenation of string literals, not to an expression;
+ needed for concatenation contexts.
+ (INTMAX_MAX, INTMAX_MIN): New macros.
+
+ * src/stat.c (print_stat): Don't assume st_ino / st_dev fits in
+ unsigned long; this isn't true for st_ino on Solaris 9.
+
+2004-08-03 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/uname.c: Do not depend on HAVE_SYSCTL when deciding
+ whether to include files. Include <sys/param.h> if
+ HAVE_SYS_PARAM_H (not HAVE_SYSCTL).
+ (main) [defined __POWERPC__]: Add a kludge to work around a
+ Mac OS X bug, so that uname -p defaults to "powerpc" if

+ * src/install.c (isdir): Remove decl.
+ (install_file_to_path): Rely on make_path to fail if the destination
+ is not a directory, by passing preserve_existing==true to it.
+ Hence we no longer need to call isdir.
+ Free dest_dir immediately when it's no longer needed, rather than
+ waiting until the end of the function.
+ (copy_file): Don't bother calling isdir, as copy will do the
+ right thing if the destination is a directory.
+
+ * src/du.c (fts_debug, opt_all, apparent_size, opt_count_all,
+ print_grand_total, opt_separate_dirs, hash_ins, process_file, main):
+ Use bool for booleans.
+ (max_depth): Now size_t, not int, to avoid an arbitrary limit
+ of INT_MAX on depth.
+ (G_fail): Remove: no longer needed, now that the relevant
+ functions return bool.
+ (process_file): Use return value to signal success rather than
+ setting a global. Remove first_call static var; not needed, since
+ we can look at n_alloc. Use size_t for depths. Remove FIXME
+ about size_t casts, as it's now fixed. Use xnrealloc rather
+ than the obsolescent XREALLOC. Don't bother to check whether
+ reallocation is needed unless level > prev_level.
+ (du_files): Invert sense of result, for consistency with
+ other coreutils code. All callers changed.
+ (main): Allow --max-depth values up to SIZE_MAX.
+
+ * src/df.c (inode_format, show_all_fs, show_local_fs,
+ show_listed_fs, posix_format, require_sync, print_type,
+ selected_fstype, excluded_fstype, show_dev, show_point, main):
+ Use bool for booleans.
+ (df_readable, show_dev): Use UINTMAX_MAX instead of -1.
+ (show_dev, show_point, main):
+ Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.
+ Don't assume disk name lengths are <= INT_MAX.
+ Rewrite pct calculation to avoid cast.
+ (show_point): Don't assume resolved length is <= SSIZE_MAX.
+
+ * src/cut.c (hash_int) [!defined UINTPTR_MAX]: Use size_t
+ instead of uintptr_t.
+ * src/shred.c (UINT_MAX_32_BITS): Remove.
+ (word32): Remove. All uses changed to uint32_t.
+ (isaac_seed_data): Remove unnecessary cast.
+ * src/system.h (ptr_align): Use size_t; in practice, this is just as
+ good as uintptr_t in checking for alignments, and has fewer
+ configuration hassles.
+
+ * src/Makefile.am (localedir.h): Make it readonly; this
+ undoes part of the 2004-07-27 patch.
+
+2004-07-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/sort.c (UCHAR): Remove; all uses changed to to_uchar.
+ (IS_THOUSANDS_SEP): Use bool when appropriate.
+ (numcompare, main): Use char, not int, when the value is always a char.
+ (numcompare): Remove "register"; compilers are smart enough these days.
+ * src/system.h (errno, CHAR_BIT): Remove decls;
+ no longer needed now we assume C89 or better.
+ Include <inttypes.h> before <stdint.h>, as it's the
+ Autoconf-recommended pattern.
+ (to_uchar): New inline function, moved here from tr.c.
+ Use full names for int types, e.g. "long int" rather than "long".
+ * src/tr.c (to_uchar): Remove; now in system.h.
+ (is_char_class_member): Use bool when appropriate.
+
+ * src/mkdir.c (create_parents, main): Use bool when appropriate.
+ (main): Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.
+
+2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/mkfifo.c (main): Use EXIT_SUCCESS and EXIT_FAILURE, not 0 and 1.

+ * src/chmod.c (recurse, force_silent, process_file, process_files,
+ main): Use bool when appropriate.
+ * src/cksum.c (cksum, main): Likewise.

+ AD_push, prompt, remove_dir): Likewise.
+ * src/rm.c (rm_option_init, main): Likewise.
+
+ * src/remove.c (top_dir, pop_dir, full_filename_):
+ Use size_t for sizes.
+ * src/cp.c (target_directory_operand): Do not clear *NEW_DST if stat
+ succeeds. It's not necessary in that case, as *NEW_DST is always
+ false already.
+ (do_copy): Rewrite slightly to avoid need for "unreachable" comment.
+ (main): Use EXIT_SUCCESS, EXIT_FAILURE instead of 0, 1.
+ * src/rm.c (main): Likewise.
+
+ md5sum, sha1sum integer cleanups.
+
+ * src/checksum.h: Don't include config.h, sys/types.h, stdio.h:
+ not needed.
+ (ALG_UNSPECIFIED): Remove.
+ (ALG_MDT): Don't make it equal to CHAR_MAX + 1; this isn't necessary.
+ * src/md5.c: Don't include any files other than checksum.h.

+ * src/md5sum.c (OPENOPTS, have_read_stdin, status_only, warn,
+ bsd_split_3, split_3, hex_digits, digest_file, digest_check, main):
+ Use bool when appropriate.
+ (digest_check): Increase limit of number of input lines to
+ UINTMAX_MAX from INT_MAX. Diagnose any overflows of this counter.
+ Use ngettext instead of hard-to-i18nize hardcoded stuff for plurals.
+
+2004-07-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/cat.c (exit_status): Remove. Now done by passing a boolean
+ 'ok' flag around.
+ (simple_cat, cat): Return true if successful. All callers changed.
+ (simple_cat, cat, main): Use bool for booleans.
+ (simple_cat): Use size_t for sizes.
+ (cat, main): Use the same names for parameters that we use for
+ long options, to avoid confusion. This inverts the sense of the
+ show_tabs (formerly output_tabs) and number_nonblank
+ (formerly numbers_at_empty_lines) variables.
+ (main): Don't mess up (due to integer overflow) if we are given
+ INT_MAX - INT_MIN + 1 options.
+ [O_BINARY]: Don't invoke isatty unless the other options require it.
+ (main): When deciding whether to use simple_cat, don't worry
+ about binary option; it's irrelevant.
+
+ * src/dcgen: Remove comments, trailing white space, and empty
+ lines from the output strings, to save space.
+ Use a narrower type like 'unsigned char' for line lengths, if
+ that will do.
+ Make the output variables static, not extern.
+
+ * src/chgrp.c (parse_group): Require base 10 when parsing
+ groups as integers.
+ (main): int -> bool when appropriate.
+ * src/chown.c (main): Likewise.
+ * src/chown-core.c: Include inttostr.h.
+ (UINT_MAX_DECIMAL_DIGITS, uint_to_string): Remove.
+ (gid_to_name, uid_to_name): Use imaxtostr/umaxtostr
+ instead of uint_to_string).
+ (describe_change): Instead of an int flag, use a char *
+ auxiliary; this avoids the need for casts.
+ Assume free (NULL) works.
+ (change_file_owner): Return true/false, not 0/-1, since
+ we don't set errno. All callers changed.
+ Use bool when appropriate.
+ (chown_files): Likewise.
+ * src/chown-core.h (chown_files): Likewise.
+
+ * tests/chown/basic: Test for proper handling of uids like
+ "010", which must be parsed as decimal.
+
+ * tests/misc/pwd: Don't assume that Perl's getpwd agrees with our
+ pwd when there are multiple names for the working directory
+ (which can happen with an automounter, sigh).
+
+ * src/Makefile.am ($(SCRIPTS)): Don't depend on Makefile;
+ this causes Solaris 8 'make' to refuse to build "groups".
+ (localedir.h): Don't depend on Makefile: this causes Solaris
+ 8 'make' to build localedir.h unnecessarily. The dependence
+ on Makefile is ineffective anyway, since $(localedir) might
+ change even if Makefile hasn't.
+
+ * src/remove.c (remove_dir): If we can't save the state of the
+ working directory, pretend we started from "/", not ".".
+ This avoids a bug on hosts like Solaris that don't let you
+ remove the working directory.
+
+2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/printf.c (strtiomax, strtoumax): Declare if not already
+ declared: this fixes a portability bug with Solaris 8 + GCC.
+ (STRTOX): Parenthesize use of macro arg as expression.
+ (vstrtoimax, vstrtoumax, vstrtold): Remove now-unnecessary
+ parentheses.
+ * configure.ac: Check for declaration of strtoumax, for
+ src/printf.c.
+
+ * src/Makefile.am (cp_LDADD, ginstall_LDADD, mv_LDADD,
+ pathchk_LDADD, rm_LDADD, test_LDADD): New vars, for eaccess.
+
+ * tests/readlink/can-e: Don't assume that we can remove the
+ working directory: this isn't possible under Solaris 8, say.
+ * tests/readlink/can-f: Likewise.
+ * tests/readlink/can-m: Likewise.
+
+ * src/copy.c (copy_internal): find_backup_file_name no longer
+ returns NULL, so don't bother to check for this.
+ * src/cp.c (do_copy): Likewise.
+ * src/ln.c (do_link): Likewise.
+
+2004-07-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/nice.c (GET_NICE_VALUE): Renamed from GET_PRIORITY.
+ All uses changed.
+ (NZERO): New macro, if system doesn't define it already.
+ (usage): Distinguish priorities from nice values.
+ Don't assume NZERO is 20.
+ (main): Use bool instead of int where appropriate.
+ If user specifies an adjustment out of range, always truncate it
+ to an inrange value instead of sometimes giving an error message
+ and sometimes not.
+ Do not assume that -1 is an error return from "nice" or
+ "getpriority", as it might be the current nice value minus NZERO.
+ If nice/setpriority fails with errno == EPERM, go ahead and run
+ the command anyway; POSIX requires this.
+
+ * src/pathchk.c: Include euidaccess.h.
+ (dir_ok): Use euidaccess, not access.
+ * src/test.c (R_OK, W_OK, X_OK, FOK): Remove; system.h defines them.
+ (eaccess): Remove. All users changed to use euidaccess instead.
+
+2004-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/uptime.c (print_uptime) [defined BOOT_MSG]:
+ Don't assume ut_line is null-terminated.
+ * src/who.c (print_line): New arguments USERLEN and LINELEN,
+ since USER and LINE might not be null terminated. All callers
+ changed.
+
+2004-07-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix bug with "tail -f" reported by Rob Holland in
+ <http://lists.gnu.org/archive/html/bug-coreutils/2004-07/msg00054.html>.
+ Also, remove the undocumented and unsupported-since-2000
+ --max-consecutive-size-changes options. Fix another related bug:
+ "tail" got confused if stdin, stdout, or stderr were closed.
+ Also, use output buffering even with "tail -f".
+
+ * NEWS: Document this, plus yesterday's patch.
+ * doc/coreutils.texi (tail invocation): "size has remained the same"
+ -> "file has not changed", which is more accurate for fifos.
+ * src/tail.c: Include fcntl-safer.h.
+ (COPY_TO_EOF): Set to UINTMAX_MAX, not OFF_T_MAX (which was wrong).
+ (COPY_A_BUFFER): New macro.
+ (struct File_spec): New members mtime, mode, blocking.
+ Remove member n_consecutive_size_changes.
+ (DEFAULT_MAX_N_CONSECUTIVE_SIZE_CHANGES,
+ max_n_consecutive_size_changes_between_opens,
+ MAX_CONSECUTIVE_SIZE_CHANGES_OPTION): Remove.
+ (long_options, tail_forever, parse_options):
+ Remove (non-)support for --max-consecutive-size-changes.
+ (record_open_fd): New function.
+ (recheck, tail_file): Use it. Don't assume that stdin is open.
+ (dump_remainder): Add support for new COPY_A_BUFFER special value.
+ Treat errno==EAGAIN like EOF, since it might be a nonblocking read.
+ (recheck): New arg BLOCKING, specifying whether to use blocking reads.
+ All uses changed.
+ (n_live_files): Remove, replacing with...
+ (any_live_files): New function. All uses changed.
+ (tail_forever): Use nonblocking I/O unless we know that blocking I/O
+ is safe; this avoids some hangs when reading from a fifo.
+ Avoid invoking fstat or sleep when using blocking I/O.
+ Do not check for changes to size if the file is not a regular file,
+ as the size is undefined in that case.
+ Check for changes to mtime or mode, too; this works for non-regular
+ files.
+ (tail_forever, main): Redo fflush strategy to work even when input
+ is nonblocking. Don't use unbuffered output; just flush when needed.
+
+2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/tail.c (main): Ignore -f if no file operand is specified
+ and standard input is a pipe.
+ * doc/coreutils.texi (tail invocation): Do not ignore -f for
+ all pipes, just for when standard input is a pipe and no
+ file operand is specified.
+ * tests/tail/Test.pm: Reinstate f-1 test, since we now pass.
+ Add a new commented-out f-2 test, which we still fail.
+ (test_vector): All f-* tests are special cases, not just f-1.
+
+2004-07-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/uptime.c: Include c-strtod.h.
+ (print_uptime): Use c_strtod instead of setlocale and sscanf.
+ Use long int rather than int to count days (for 64-bit hosts),
+ and check for arithmetic overflow when converting double to time_t.
+
+2004-07-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/printf.c (vstrtold): Renamed from vstrtod.
+ Now returns long double. All uses changed.
+ (print_direc): Use "L" length modifier when printing floating point
+ numbers, since we're now printing long double.
+
+2004-07-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Version 5.3.0.
+
+ printf cleanup, to avoid undefined behavior, to add support for
+ formats that Bash supports, and to support wide integers like
+ Bash does.
+
+ * NEWS: Document this.
+ * src/printf.c (UNSPECIFIED): Remove. All uses now replaced by
+ booleans, so that we don't reserve any values for precision or
+ width (like Bash).
+ (STRTOX): Use prototype, not K&R-style definition.
+ (vstrtoimax): Renamed from xstrtol (to avoid confusion with xstrtol
+ in ../lib), with type change to intmax_t.
+ All uses changed.
+ (vstrtoumax): Renamed from xstrtoul, with type change to uintmax_t.
+ All uses changed.
+ (vstrtod): Renamed from xstrtod. All uses changed.
+ (print_direc): Use boolean arg instead of special value to indicate
+ a missing precision or width. LENGTH no longer includes
+ length modifiers or conversion character. New arg CONVERSION
+ now specifies conversion character.
+ Use intmax_t-width formatting for integers (like Bash).
+ Add support for C99 %a, %A, %F (like Bash).
+ Add support for field width with %c (POSIX requires this).
+ Add a FIXME for lack of support for field width and precision
+ for %b.
+ Add support for '\'', '0' flags.
+ Check for invalid combinations of flags, field width, precision,
+ and conversion, to prevent use of undefined behavior.
+ Allow multiple length modifiers, for formats like "%lld" (like Bash).
+ Add support for C99 'j', 't', 'z' length modifiers (like Bash).
+ In error message, output entire invalid conversion specification,
+ instead of merely outputting % followed by the conversion char.
+ * tests/misc/printf: Add tests for the above.
+
+2004-04-03 Dmitry V. Levin <ldv@altlinux.org>
+
+ Change "readlink -f" to be more compatible with prior implementations.
+ Add more canonicalize options, -e and -m.
+ Add comprehensive tests for all readlink modes.
+
+ * m4/canonicalize.m4 (AC_FUNC_CANONICALIZE_FILE_NAME):
+ Do not add canonicalize.c here.
+
+ * src/readlink.c (longopts): Add new options.
+ (usage): Document them.
+ (canonicalize_fname): New proxy function.
+ (main): Handle new options.

+
+2004-07-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/copy.c (copy_dir): Assume path_concat returns non-NULL.
+ * src/cp.c (do_copy): Likewise.
+ * src/mv.c (movefile): Likewise.
+
+ * src/cp.c (make_path_private): 2nd arg is now size_t, not int,
+ to avoid problem when path_concat dir name is longer than 2 GiB (!).
+
+ * src/nohup.c (main): Don't pass NULL first argument to path_concat.
+ This cleans up the semantics a bit, as we no longer try to open the
+ same file twice.
+
+2004-07-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Add short names -t and -T for --target-directory

+
+2004-06-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ Add support for --no-target-directory option.
+
+ * NEWS: Document it.
+ * doc/coreutils.texi (Common options, Target directory, cp

+ (ln invocation): Explain that --no-target-directory subsumes
+ --no-dereference.
+ (unlink invocation): Modify wording to match new wording in
+ link invocation.
+
+ * src/cp.c (NO_TARGET_DIRECTORY_OPTION): New constant.

+ invoking subshell, then turn it back on if VERBOSE=yes afterward.
+
+2004-06-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ Add support for 'install --target-directory', an option

+
+2004-06-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Use more-consistent rules among cp, ln, and mv when dealing with
+ last operands that are (or look like) directories.
+
+ * src/cp.c (target_directory_operand): New, nearly-common function,
+ It reports an error if the destination appears to be a directory
+ (e.g., because it has a trailing slash) but is not.
+ * src/ln.c, src/mv.c: Likewise.
+ * src/cp.c (do_copy): Use it.
+ * src/ln.c (main): Likewise.
+ * src/mv.c (main): Likewise.
+
+ * src/cp.c (do_copy): Don't assume argc is positive.
+ Don't bother to lstat dest, since copy() will do that for us.
+ Use "const" to avoid the need for cast.
+
+ * src/cp.c (do_copy): Don't output a usage message because of file
+ problems (e.g., an operand is not a directory). Use it only for
+ syntax. Standardize on "target %s is not a directory" for the
+ diagnostic.
+ * src/ln.c (main): Likewise.
+ * src/mv.c (main): Likewise.
+
+ * src/cp.c (do_copy): Remove test for trailing slash, since
+ target_directory_operand now does this.
+ * src/ln.c (main): Likewise.
+ * src/mv.c (movefile): Likewise.
+
+ * src/cp.c (main): Reject multiple target directories.
+ Check whether a specified target is a directory when parsing the

+ * src/ln.c (main): Likewise.
+
+ * src/ln.c (isdir): Remove decl; no longer needed.
+ * src/mv.c (isdir, lstat): Likewise.
+
+ * src/ln.c (do_link): New arg dest_is_dir. All uses changed.
+ Don't check the destination ourself; rely on dest_is_dir.
+ This way we can avoid lstatting the destination in the
+ usual case, and in the worst case we lstat 1, not 3 times.
+ Don't bother to unlink unless link failed; this saves a syscall.
+ Remove unnecessary backup_succeeded flag;
+ it was identical to "dest_backup != NULL".
+
+ * src/ln.c (main): Use int to count to argc, not unsigned int.
+ This handles negative operand counts.
+ * src/mv.c (main): Likewise.
+
+ * src/mv.c (do_move): Don't call hash_init; expect the caller to
+ do it, for consistency with cp.c and ln.c. All callers changed.
+ (movefile): dest_is_dir parameter is now bool, not int.
+ (main): Standardize on "missing destination file operand after %s"
+ for the diagnostic, for consistency with cp.c.
+
+ * tests/mv/diag: Don't assume "mv --target=nonexistentdir"
+ will complain about the arg count.
+ Adjust to new (briefer) diagnostics.
+ * tests/cp/fail-perm: Add a test to verify that we get the new
+ diagnostic when failing to copy through a symlink-to-inaccessible-dir.
+
+2004-06-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix a bug: formerly, if d/x was a directory and x a file, "ln x
+ d/" incorrectly created a link d/x/x. It also saves some system
+ calls.
+
+ * NEWS: Document the fix.
+
+ * src/ln.c (main): Don't append basename to dest if this
+ results in an existing directory name.
+ * tests/ln/misc: See whether a trailing slash is followed too far.
+
+2004-06-26 Jim Meyering <jim@meyering.net>
+
+ * src/printf.c (main): When given no arguments, print the standard
+ "missing operand\nTry printf --help..." message -- to be consistent.
+
+2004-06-26 Jim Meyering <jim@meyering.net>
+
+ * src/mknod.c (main): Add \n at the end of message output via fprintf.
+
+2004-06-25 Jim Meyering <jim@meyering.net>
+

+
+2004-05-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ Several fixes to chgrp and chown for compatibility with POSIX and BSD:
+
+ Check for incompatible options. When -R and --dereference are
+ both used, then either -H or -L must also be used. When -R and -h
+ are both used, then -P must be in effect.
+
+ -H, -L, and -P have no effect unless -R is also specified.
+ If -P and -R are both specified, -h is assumed.
+
+ Do not optimize away the chown() system call when the file's owner
+ and group already have the desired value. This optimization was
+ incorrect, as it failed to updated the last-changed time and reset
+ special permission bits, as POSIX requires.
+
+ Do not report an error if the owner or group of a
+ recursively-encountered symbolic link cannot be updated because
+ the file system does not support it.
+
+ * NEWS: Document the above.
+
+ * src/chgrp.c (main): Check for incompatible options. -R --dereference
+ requires either -H or -L, and -R -h requires -P. If -H, specify
+ FTS_PHYSICAL as well as FTS_COMFOLLOW; this is faster. Make this
+ file as much like chown.c as possible.
+ * src/chown.c (main): Likewise.
+
+ * src/chown-core.c (change_file_owner): Use ent->fts_statp only if
+ needed. Chown a directory only after chowning its children; this
+ avoids problems if the new directory ownership doesn't permit
+ access to the children. Dereference symlinks before doing
+ ROOT_DEV_INO_CHECK, not after, so that we catch symlinks to /.
+ Do not optimize away the chown() system call when the file's owner
+ and group already have the desired value. POSIX does not permit
+ this optimization. Rely on chown and lchown to do the right
+ thing with symlinks and/or -1 arguments, now that we have wrappers
+ to do this. Use ENOTSUPP not ENOSYS, and ignore all ENOTSUPP
+ errors, not just command-line errors.
+ (chown_files): Pass FTS_NOSTAT to xfts_open if we don't need file status.
+
+ * src/system.h (ENOTSUP): Remove.
+
+ * tests/chgrp/basic: Use chown --from to discover whether the
+ group changed, since chgrp now changes unconditionally. This
+ complicates the sed script a bit. Do not specify --dereference,
+ since it's the default (and we want to test this). Adjust output
+ to match the fact that chgrp no longer optimizes the case of
+ changing a file's group to the same value as before.
+ * tests/chgrp/posix-H: Do not attempt to combine -h and -H; these
+ options are incompatible, and their behavior is undefined with POSIX.
+ (changed, not_changed): Adjust to match the fact that -h is no longer
+ specified. Sort names.
+ * tests/chown/deref: Adjust error-diagnostic spelling to match new
+ behavior.

+ (skip): If fdesc is standard input, advance the input offset.
+ Do not quit if reading, and if noerror was specified;
+ POSIX seems to require this.
+ If read fails on output file, report the earlier lseek failure
+ instead; this fixes a FIXME in dd_copy.
+ (advance_input_after_read_error): New function.
+ (dd_copy): Use it, instead of assuming that failed reads
+ do not advance the file pointer. Advance input offset
+ after nonfailed reads. Advance only a partial block if

+ do not generate an output block of zeros in this case.
+ (main): Determine initial input offset, seekability of input,

+ to an unsigned char are now done this way, not by ad-hoc methods.
+ (count): New type. Use it whenever counts or states are needed.
+ (BEGIN_STATE): Increase from INT_MAX - 1 (which was bogus, anyway,
+ since we used it in an unsigned int context) to UINTMAX_MAX - 1.
+ (REPEAT_COUNT_MAXIMUM): New macro. Use it in place of BEGIN_STATE
+ whenever appropriate.
+ (NOT_A_CHAR): Remove global macro; now a local enum.
+ (UL_LOWER, UL_UPPER, UL_NONE): No longer specify values, since
+ the rest of the code no longer depends on them.
+ (class_ok): Remove; all uses changed to use inline comparisons.
+ (RE_NO_TYPE): Remove; wasn't used or needed.
+ (struct List_element): normal_char and equiv_code are now unsigned
+ char, not int.
+ first_char, last_char, and the_repeated_char are now unsigned char,
+ not unsigned int. repeat_count is now count, not size_t.
+ All uses changed.
+ (struct Spec_list): state is now count, not unsigned int.
+ lengthis now count, not size_t.
+ n_indefinite_repeats is now size_t, not int.
+ has_equiv_class, has_char_class, and has_restricted_char_class
+ are now bool, not int. All uses changed.
+ (struct E_string): s is now char *, not unsigned char *.
+ escaped is now bool *, not int *. All uses changed.
+ (ES_MATCH): Remove macro, replacing with:
+ (es_match): New inline function. All uses changed.
+ (squeeze_repeats, complement, posix_pedantic, truncate_set1,
+ translating): Now bool, not int.
+ (io_buf): Now char array, not unsigned char.
+ (SET_TYPE): Remove. All uses replaced with bool.
+ (is_equiv_class_member, unquote, append_range, append_char_class,
+ append_equiv_class, find_closing_delim, star_digits_closebracket,
+ build_spec_list, parse_str, homogeneous_spec_list):
+ Now returns bool, not int. All uses changed.
+ (is_equiv_class_member): Now inline.
+ (is_equiv_class_member, is_char_class_member, make_printable_str,
+ append_normal_char, append_range, append_repeated_char,
+ get_s2_spec_stats):
+ Args are now of proper integer type.
+ (unquote, look_up_char_class, make_printable_str,
+ append_equiv_class, build_spec_list, squeeze_filter):
+ Avoid unsigned char *p; gently convert *p to unsigned char instead.
+ (unquote, get_spec_stats): Do not jump past declarations and then
+ use them; C doesn't allow this in portable programs.
+ (make_printable_str): Check for overflow in size calculations.
+ (xmemdup): Remove. All uses rewritten.
+ (find_bracketed_repeat): Args are now of proper pointer-to-integer
+ type. Do not reject [c*0]. Use xstrtoumax, not xstrtoul.
+ (find_bracketed_repeat, star_digits_closebracket): Check that the
+ digits are not escaped.
+ (build_spec_list): Don't bother to copy opnd_str; not needed.
+ (build_spec_list, get_next): Simplify internal logic a bit.
+ (card_of_complement): Fix bug due to char overflow.
+ (get_spec_stats): Don't assume len fits into int.
+ Check for integer overflow. Use abort() rather than assert(0).
+ (string2_extend): Fix subscript error: is_char_class_member (..., 255)
+ was being invoked.
+ (squeeze_filter): READER is never null now; simplify code.
+ READER arg now has a simpler type. Remove unnecessary casts.
+ (squeeze_filter, main): Calls to fwrite improperly checked result
+ against zero, rather than against requested size.
+ (plain_read): New function.
+ (read_and_delete, read_and_xlate):
+ Remove unused filter arg, and don't worry about hit_eof.
+ Simplify by using plain_read.
+ (set_initialize): Args are bool and bool *, not int and SET_TYPE *.
+ (main): Always pass a non-null procedure to squeeze_filter.
+ Rewrite so that class_ok isn't needed.

+ Eliminate an unnecessary call to AC_stack_top.
+ (remove_dir): Change type of cwd_state parameter to `struct cwd_state'
+ so we can now communicate to caller whether/how functions like

+2004-05-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ In shred, check for errors from fdatasync more carefully. If
+ fdatasync fails with errno==EINVAL, it means this implementation
+ does not support synchronized I/O for this file. Do not report
+ this as an error, as (for example) AIX 5.2 fdatasync reports it
+ for raw disk devices. Problem reported by Albert Chin in
+ <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00028.html>.
+
+ Check for write errors, though: the old code ignored them.
+ Improve error checking in a few other cases, too (e.g., close of a
+ directory).
+
+ Also, change several 'int' values to 'bool', so that the error
+ checking is a bit clearer. Similarly, change unsigned values
+ to size_t where appropriate.
+
+ * src/shred.c: Include "dirname.h".
+ (datasync) [!HAVE_FDATASYNC]: Remove.
+ (dosync): New function.
+ (dopass): Use it. Return 1 on write error, -1 on other error.
+ All callers changed. Report write error if dosync does.
+ (do_wipefd, wipefd, wipename, wipefile): Return bool (true/false),

+
+ * src/remove.c (remove_entry): Check for errno values like ENOENT
+ that show the file cannot be directory, instead of for errno
+ values like EPERM that show the file might be a directory. This
+ is necessary because, when a single unlink() call has multiple
+ reasons to fail, it can set errno to any of those reasons; it's
+ only the rare errno value like ENOENT that excludes all the other
+ possible reasons to fail even when the file is a directory.
+ (remove_cwd_entries): Don't attempt chdir if the file is known
+ to not be a directory.
+ (remove_dir): Use the same method that remove_cwd_entries uses
+ (for some reason they differed). Don't assert that saved_errno
+ must be EPERM; it might be just about anything.

+
+ Fix POSIX-conformance bug: "sort -k 3,3.5b" is supposed to skip
+ leading blanks when computing the location of the field end;
+ it is not supposed to skip trailing blanks. Solaris 8 "sort"
+ does conform to POSIX. Also fix the documentation to clarify
+ this and related issues.
+
+ * doc/coreutils.texi (sort invocation): Mention -k earlier, so
+ that the options are in alphabetical order. Describe how -b works
+ more-accurately; this involves fixing some examples, too. Mention
+ what happens if the start field falls after an end field or after
+ a line end. Warn about using -k without -b, -g, -M, -n, or -t.
+ Add an example of how to sort IPv4 addresses and Apache Common
+ Log Format dates. Remove a duplicate example.
+ (Putting the tools together): Use separate options rather
+ than agglomerating them.
+ * src/sort.c (limfield): Use skipeblanks, not skipsblanks, to

+ (trailing_blanks): Remove.
+ (fillbuf, getmonth, keycompare): Don't trim trailing blanks.
+
+ * tests/pr/Test.pm: Fix typo in env_default comment.

+
+2004-04-22 Paul Eggert <eggert@twinsun.com>
+
+ More signal-handling cleanup for ls.c. Do not allow signals to
+ happen between arbitrary output bytes, as the
+ restore-default-color sequence can bollix up multibyte chars or
+ color-change sequences in the ordinary output. Instead, process
+ signals only between printing a file name and changing the color
+ back to non_filename_text color. That way, if the signal handler
+ changes the color (to the default), 'ls' will change it back when
+ 'ls' continues (after being suspended).
+
+ Also, do not bother with signal-handling unless stdout is a
+ controlling terminal; this lets stdio buffer better when "ls
+ --color" is piped or sent to a file.
+
+ * src/ls.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: New macros.
+ Do not include "full-write.h"; no longer needed.

+ put_indicator.
+ (caught_signals, interrupt_signal, stop_signal_count): New vars.
+ (restore_default_color): Don't bother checking for put_indicator
+ failure.
+ (sighandler): Don't handle SIGTSTP; that's another handler now.
+ Simply set interrupt_signal to the signal, then exit.
+ (stophandler, process_signals): New functions.
+ (main): Don't output any color changes until _after_ the signal
+ handlers are set up. This fixes a race condition where 'ls'
+ could be interrupted while initializing colors, and leaving the
+ terminal in an undesirable state.
+ Don't mess with signal-handling if standard output is not a
+ controlling terminal.
+ When exiting, restore the default color, then restore the
+ default signal handling, then act on any signals that weren't
+ acted on yet.
+ Do not print //DIRED// etc. in colors; this avoids the need
+ to catch signals when printing them.
+ (print_name_with_quoting): Process signals just before switching
+ color back to non_filename_text.

+
+ Signal-handling cleanup for coreutils. Here are the highlights:
+
+ - csplit sometimes failed to remove files when interrupted.
+ - csplit didn't clean up if two signals arrived nearly simultaneously.
+ - install -s would infloop on System V if SIGCHLD was ignored.
+ - ls could incorrectly restore color if multiple signals
+ arrived nearly simultaneously.
+
+ * src/csplit.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
+ Define.
+ (filename_space, prefix, suffix, digits, files_created, remove_files):

+ (caught_signals): New var.
+ (cleanup): Block signals while deleting all files.
+ (cleanup_fatal, handle_line_error, regexp_error):

+ (create_output_file, close_output_file, interrupt_handler):
+ Block signals while changing the number of output files,
+ to fix some race conditions.
+ (delete_all_files): Do nothing if remove_files is zero.
+ Clear files_created.
+ (main): Don't mess with signals until after argument processing
+ is done.
+
+ * src/csplit.c (main): Rewrite signal-catching code to make it
+ similar to other coreutils programs. When processing signals,
+ block all signals that we catch, but do not block signals that we
+ don't catch. Avoid problems with unsigned int warnings.
+ * src/ls.c (main): Likewise.
+ * src/sort.c (main): Likewise.
+
+ * src/csplit.c (interrupt_handler):

+ * src/tee.c (main) [!defined _POSIX_SOURCE]: Likewise.
+
+ * src/install.c: Include <signal.h>.
+ (main) [defined SIGCHLD]: Set SIGCHLD handler to the default, if -s is
+ given, since System V fork+wait does not work if SIGCHLD is ignored.
+
+ * src/ls.c (sighandler) [!defined SA_NOCLDSTOP]: Reset signal
+ handler to self, not to SIG_IGN, since SIGTSTP can be received
+ more than once.
+ (main): Use SA_RESTART, as that is simpler than checking for EINTR
+ failures all over the place.
+
+2004-04-20 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (is_empty_dir): Clarify comment.

+2004-04-08 Jim Meyering <jim@meyering.net>
+
+ * src/dd.c (dd_copy): Mark two diagnostics for translations.
+ (set_fd_flags): Undo part of today's change: it's a little
+ cleaner -- and more efficient in the common case -- to go
+ ahead and OR in the -1 when fcntl fails.
+
+ * Makefile.maint (sc_dd_max_sym_length): New target.
+ (syntax-check-rules): Add it.
+
+ * src/md5sum.c (PROGRAM_NAME) [algorithm == ALG_SHA1]:

+ (LONGEST_SYMBOL): New macro.
+ (struct symbol_value): Renamed from struct conversion. Members
+ symbol and value renamed from convname and conversion. The

+ (conversions): Add nocreat, excl, fdatasync, fsync. Now const.
+ (flags): New constant array.
+ (iflag_error_msgid, oflag_error_msgid): New constants.
+ (parse_symbols): Renamed from parse_conversion and generalized

+
+2004-03-31 Jim Meyering <jim@meyering.net>
+
+ * tests/Fetish.pm (run_tests): Remove `.orig' file.

+ Prompted by a report of Solaris 8 differences from Paul Eggert.
+
+ * tests/Fetish.pm: Accept new directives: OUT_SUBST, ERR_SUBST.
+ Rename `%tmp' to `%actual'. Reverse order of last two args to

+
+2004-03-28 Paul Eggert <eggert@twinsun.com>
+
+ Fix some gotchas encountered when porting to Solaris 8, using

+
+ * src/hostname.c [HAVE_SETHOSTNAME && !defined sethostname]:

+ * src/who.c: Include "vasprintf.h", for asprintf.
+
+2004-03-28 Jim Meyering <jim@meyering.net>
+
+ Minor optimization:
+ * src/du.c (process_file): Don't record dev/inode for directories.
+
+ Under some circumstances, without -c, du would mistakenly count the
+ space of hard-linked files, not just the first one it encountered.
+ Reported by Anthony Thyssen.
+ * src/du.c (du_files): Don't ever clear the set of `seen' dev/inodes.

+2004-03-23 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS: Shorten the du --files0-from announcement, and say
+ "NUL-terminated" rather than "NUL-separated".
+ * src/du.c (EXPECTED_BYTES_PER_FILE_NAME, DEFAULT_PROJECTED_N_FILES):
+ Remove: not used.
+ (usage): Say "NUL-terminated", not "NUL-separated".
+ (main): Check for I/O error when istream is closed.

+
+2004-03-22 Jim Meyering <jim@meyering.net>
+
+ * man/Makefile.am (.x.1): Remove --info-page= option, reverting
+ the change of 2004-01-22. I can no longer reproduce the problem
+ that prompted that change, and `info coreutils pr' would display the

+
+ * tests/du/files0-from (nul-1, nul-2): Adjust expected diagnostics
+ to match corrected output.
+
+ * src/du.c: Include "readtokens0.h" rather than "readtokens.h".

+
+2004-02-29 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS: Add support for a new notation @N to get_date to represent
+ the time stamp with numeric value N. Improve support for
+ fractional time stamps. date's -d and -f options now accept them.
+ Likewise for touch -t. date has a new option --iso-8601=ns.
+
+ * doc/coreutils.texi (touch invocation):
+ Describe use of fractional seconds.
+ (date invocation, Options for date): Likewise.
+ * doc/getdate.texi (General date syntax, Time of day items): Likewise.
+ * doc/coreutils.texi (date invocation): Mention effect of LC_TIME.
+ (Options for date): Describe new --iso-8601=ns option.
+
+ * doc/getdate.texi: Add copyright notice. Change getdate to
+ get_date when talking about the function name.
+ (Seconds since the Epoch): New section, containing the time_t

+ info about the @ syntax. Mention negative time stamps,
+ fractional time stamps, and leap seconds.
+ (General date syntax): Modernize examples a bit to reflect new
+ features.
+ (General date syntax, Relative items in date strings):
+ Use ' rather than " to quote formats.
+ (Time of day items): Add an example with fractional seconds.
+ Describe fractional-second syntax.
+
+ * src/Makefile.am (touch_LDADD): New macro, since `touch' now
+ needs clock_gettime.
+
+ * src/date.c (enum Time_spec): New enum TIME_SPEC_NS.
+ (time_spec_string, time_spec, show_date): Support it.
+ (usage): Remove description of -ITIMESPEC, as it's obsolete and
+ confusing. Mention --iso-8601=ns.
+ (batch_convert): getline returns ssize_t, not int.
+
+ * src/touch.c (newtime): Now an array of two timespecs, one
+ for access and one for modification.
+ (ref_stats): Remove.
+ (get_reldate): Use get_date's parameter profile.
+ (touch, main): Adjust to above changes.
+ (main): Work even if tm_year == INT_MAX (so long as long int is wider).
+ Use gettime instead of gettimeofday, for new get_date signature.
+
+ * tests/date/Test.pm (test_vector): New tests epoch, ns-10, ns-max32,

+
+2004-03-15 Jim Meyering <jim@meyering.net>

+
+2004-03-14 Jim Meyering <jim@meyering.net>

+
+ * src/cp.c (do_copy): Tweak wording in a diagnostic.
+ Suggestion from Karl Berry.

+ Suggestion from Dan Jacobson.
+
+2004-03-12 Jim Meyering <jim@meyering.net>
+
+ * Version 5.2.1.
+
+ Sometimes, when source and destination partition are different,
+ mv mistakenly fails to preserve a hard link. Reported by IIDA Yosiaki.
+
+ * src/copy.c: When moving a set of N hard-linked files between
+ partitions, via two or more command line arguments where the
+ command line argument containing the Nth link contains no other
+ link to that same file, mv would mistakenly copy the file, rather
+ than hard-linking it to the other(s). That happens because when the
+ final link is processed, its link count has been reduced to 1 since
+ the other links have been `copied' to the destination partition
+ and the source links have been removed.
+ (copy_internal): When in move mode, use the source dev/inode
+ pair to look up destination name even when st_nlink == 1.
+ * src/cp-hash.c (src_to_dest_lookup): New function.
+ * src/cp-hash.h (src_to_dest_lookup): Add prototype.
+ * tests/mv/part-hardlink: New file. Test for the above fix.
+ * tests/mv/Makefile.am (TESTS): Add part-hardlink.
+
+ * announce-gen: Sync with autoconf.
+
+ * tests/ls/time-1: Exit 77 (not 1) if we can't set up for the test.
+ This was triggered on a Linux-2.2.19 system using a file system
+ NFS-mounted from some sort of Sun.
+
+2004-03-11 Jim Meyering <jim@meyering.net>
+
+ * Use automake-1.8.3. Regenerate dependent files.
+
+2004-03-10 Jim Meyering <jim@meyering.net>
+
+ * tests/du/deref-args: Also convert sizes in the 70-79 kB range,
+ so that this test works with SELinux-enabled systems.
+ Based on a patch from Tim Waugh.
+
+ `join -1 x' would give a misleading diagnostic
+ * src/join.c (string_to_join_field): Report that a non-numeric field
+ number is invalid, rather than `so large that it is not representable'.
+ * tests/join/Test.pm (invalid-j): New partial test for the above fix.
+
+2004-03-06 Jim Meyering <jim@meyering.net>
+
+ cp --sparse=always sparse-image-file.img /dev/hda1 could
+ produce an invalid copy on the destination device.

+
+2004-02-21 Jim Meyering <jim@meyering.net>
+
+ * src/comm.c (usage): Tell what comm does when there are no options.
+ Reword in terms of FILE1 and FILE2 rather than `left file' and
+ `right file'. Suggestion from Dan Jacobson.
+
+2004-02-15 Paul Eggert <eggert@twinsun.com>
+
+ Fix some POSIX-conformance bugs in expr.
+
+ * NEWS: document the following changes to src/expr.c.
+ * doc/coreutils.texi (expr invocation): Likewise.
+ Document what forms integers may take, and say "integer"
+ consistently instead of "number". Warn about operands
+ that "expr" can misinterpret, and how to work around the
+ problem.
+ * src/expr.c (eval, eval7, eval6, eval5, eval4, eval3, eval2, eval1):
+ Accept a bool argument specifying whether to evaluate the
+ expression. This is to allow short-circuit evaluation. All
+ callers changed.
+ (null): Report that a string is zero even if it has
+ a form like "-0" or "00".
+ (eval1, eval): Use short-circuit evaluation for | and &.
+ (eval): Return 0 if both arguments are null or zero, instead
+ of returning the first argument.
+ * tests/expr/basic: Add some tests for the above.
+
+2004-02-17 Jim Meyering <jim@meyering.net>
+
+ * Version 5.2.0.
+
+ `make check' from a build inside a chroot environment would fail
+ * tests/help-version: Specify an argument (`/') for df, in the
+ unusual event that there is no valid entry in /etc/mtab.
+ Likewise for id: add the -u option, so we don't get spurious

+ Patch by Tim Waugh.
+
+ * src/sort.c (usage) [-u]: Add punctuation so that the description in

+ Reported by Tim Waugh.
+ [-T]: Add a semicolon, for the same reason.
+
+2004-02-15 Jim Meyering <jim@meyering.net>
+

+
+2004-02-11 Jim Meyering <jim@meyering.net>
+
+ * tests/Makefile.am.in ($(srcdir)/Makefile.am): Use more portable
+ $(srcdir)/../Makefile.am.in, rather than $<.
+ Suggestion from Michael Elizabeth Chastain.
+
+2004-02-10 Jim Meyering <jim@meyering.net>
+
+ * config/install-sh: Make this script executable.
+ * Makefile.am (dist-hook): New target, to ensure that config/install-sh
+ is executable. Otherwise, on systems that lack a suitable install
+ binary, `make install' would fail, because of the way this script
+ is invoked (without `$SHELL ' prefix).
+ Reported by Bob Proulx.
+
+2004-02-08 Jim Meyering <jim@meyering.net>
+
+ * Version 5.1.3.
+
+ * tests/rm/rm5: Avoid triggering a bug in OSF/Tru64's sed
+ that would cause an unwarranted test failure.
+ * tests/rm/rm3: Likewise.
+
+2004-02-07 Jim Meyering <jim@meyering.net>
+
+ Remove xstat function pointer member. The way it was used was not
+ portable, since some systems (OSF V5.1, Solaris 2.5.1) provide static
+ inline `stat' and `lstat' functions, thus making the tests of
+ `xstat == lstat' in copy.c always fail.
+ * src/copy.h (struct cp_options) [xstat]: Remove member.
+ (XSTAT): New macro.
+ * src/copy.c (copy_dir): Set `.dereference' member, not .xstat.
+ (copy_internal): Use `XSTAT (x, ...)' in place of `*(x->xstat) (...)'.
+ Use `x->dereference == DEREF_NEVER' in place of `x->xstat == lstat'.
+ (valid_options): Remove now-obsolete FIXME comments.
+
+ * src/cp.c (re_protect): Use `XSTAT (x, ...)' in place of

+ (main): Remove code that set x.xstat.
+ * src/mv.c (cp_option_init): Don't initialize xstat member.
+ * src/install.c (cp_option_init): Likewise.
+
+ * Makefile.cfg (gnu_ftp_host-alpha, etc.): Un-factor .gnu.org suffix,
+ so that emit_upload_commands can use these variables, too.
+
+2004-02-06 Jim Meyering <jim@meyering.net>
+
+ * tests/rm/deep-1: Remove `du' stack space test.
+ Apparently, `ulimit -s N' isn't portable enough.
+ This test will be restored (with a guard against losing ulimit)
+ in its own file later.
+
+ * tests/rm/deep-1 (deep): Remove progress-style diagnostics,
+ since this test doesn't take long enough to merit them.
+ Run du on $tmp (the containing dir), not $deep, the full path to leaf.
+
+ * Makefile.maint (signatures): Remove definition.
+ Now, automake's gnupload handles this.
+ (%.sig: %): Remove now-unused rule.
+ (rel-files): Use automake's $(DIST_ARCHIVES), rather than
+ `$(distdir).tar.bz2 $(distdir).tar.gz'.
+ (emit-upload-commands): Adjust to use gnupload.
+
+2004-02-05 Jim Meyering <jim@meyering.net>
+
+ * src/system.h (ST_TIME_CMP_NS, ST_TIME_CMP): Remove definitions.
+ (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
+ Now, those are all defined in timespec.h.
+ Include timespec.h.
+
+ * src/date.c: Don't include timespec.h, now that system.h does it.
+
+2004-02-02 Paul Eggert <eggert@twinsun.com>
+
+ Don't dump core if localtime returns NULL (possible on
+ hosts with 64-bit time_t and 32-bit int).
+ * src/date.c: Include "inttostr.h".
+ (batch_convert, main):
+ If time conversion fails, exit with nonzero status.
+ (show_date): Return int to report conversion failure.
+ Print the time as an int if localtime fails.
+ * src/uptime.c: Print "??" if the current clock can't
+ be converted by localtime. This won't happen until the year
+ 2*31 + 1900, but we don't want to dump core even if the current
+ clock has the wrong value.
+
+ * src/stat.c: Include "inttostr.h".
+ (human_time): Print the date/time as a number of seconds since the
+ epoch if it can't be converted by localtime. This is better than
+ just saying "invalid", and is consistent with what "ls" does.
+ Don't dump core if the year has more than 48 digits; this isn't
+ possible on any contemporary host, but we might as well do it right.
+
+2004-01-31 Paul Eggert <eggert@twinsun.com>
+
+ * src/stat.c (human_time): Accept time rather than
+ pointer-to-const-time parameter, for clarity. All callers changed.
+
+2004-02-02 Jim Meyering <jim@meyering.net>
+
+ * src/stat.c (do_stat): Remove extra trailing newline from
+ default formats. Reported by Nelson H. F. Beebe.
+
+ Print actual fractional seconds in time stamps, not just `.00000000'.
+ * src/stat.c (human_time): Add and use new parameter, t_ns.
+ (print_stat): Update callers.
+ * src/ls.c (TIMESPEC_NS): Remove definition.
+ * src/system.h (TIMESPEC_NS): Define here, instead, now that stat.c
+ also uses this macro.
+ Nelson H. F. Beebe noticed that ls --full-time printed nonzero
+ fractional seconds for files on an XFS file system, but that stat's
+ fractional seconds were always zero.
+
+2004-01-28 Paul Eggert <eggert@twinsun.com>
+
+ * src/seq.c (print_numbers): Use 'double' for loop index, not
+ 'int', to avoid problems with integer overflow. On almost all
+ machines 'double' works in every case where 'int' works, and
+ it works on other cases besides.
+
+2004-01-27 Jim Meyering <jim@meyering.net>
+
+ * src/seq.c (usage): Mention that if INCREMENT is omitted,
+ it defaults to 1, even when FIRST is larger than LAST.
+ Reword so as not to exclude the possibility that INCREMENT be zero.

+ so it works on systems with Perl installed somewhere other than in
+ /usr/bin.
+
+ * src/paste.c (paste_parallel): Declare local, chr, to be of type
+ `int', not `char', since it must hold EOF. This bug would make
+ paste infloop on some systems. Test failures reported by
+ Nelson H. F. Beebe and Christian Krackowizer.
+
+2004-01-22 Jim Meyering <jim@meyering.net>
+
+ * tests/rmdir/fail-perm: New file. Test for just-fixed rmdir bug.
+ * tests/rmdir/Makefile.am (TESTS): Add fail-perm.
+
+ * man/help2man: Fix it so using --info-page='coreutils PROG' works.
+ * man/Makefile.am (.x.1): Invoke our own (tweaked) copy of help2man.
+ Use --info-page='coreutils PROG' option.
+ Now, readlink.1 refers the user to `info coreutils readlink'
+ rather than to `info readlink'. Reported by Matt Swift.

+
+2004-01-20 Diego Biurrun <diego@biurrun.de>

+
+2004-01-19 Paul Eggert <eggert@twinsun.com>

+ From Andreas Schwab.
+
+ * tests/Makefile.am (TESTS_ENVIRONMENT): Remove `/vg' (prerelease test
+ remnant) from PATH component. That would cause tests in this directory

+
+ (extract_field): Renamed from ADD_FIELD, as it's now a function.

+
+ (empty_filler): Now const *.
+

+

+ (print_many_per_line, print_horizontal): Use it.
+ (decode_switches): Set max_idx here, not in calculate_columns.
+ (print_current_files): Don't call init_column_info; calculate_columns

+
+ csplit cleanup.
+
+ * doc/coreutils.texi (csplit invocation):
+ The regexp offset need not have a sign; POSIX requires support
+ for signless offets.
+
+ Be more careful about int widths. For example, remove some
+ arbitrary limits by replacing 'unsigned' with 'size_t',
+ 'uintmax_t', etc. Use standard bool rather than a homegrown type.
+ * lib/Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.
+ * src/csplit.c (FALSE, TRUE, boolean): Remove. All uses changed
+ to <stdbool.h> usage.
+ (struct control): offset is now intmax_t, not int.
+ repeat_forever is now bool, not int.
+ (struct cstring): len is now size_t, not unsigned int.
+ (struct buffer_record): bytes_alloc, bytes_used, num_lines are now
+ size_t, not unsigned. start_line, first_available are now
+ uintmax_t, not unsigned.
+ (hold_count, control_used): Now size_t, not unsigned.

+ or int.
+ (get_first_line_in_buffer, find_line, write_to_file,
+ handle_line_error, process_line_count, regexp_error, process_regexp,
+ split_file):
+ File line, byte, and repetition counts are now uintmax_t, not unsigned.
+ (check_for_offset): Don't require a sign before the offset.
+ Use xstrtoimax to do the real work.
+ (extract_regexp): Remove harmful cast of size to unsigned.
+ 256 -> 1<<CHAR_BIT, for clarity.
+ (get_format_flags): Return at most 3, to avoid worries about overflow.
+
+ (bytes_to_octal_digits): Remove.
+
+ (cleanup): Don't check whether output_stream is NULL, since
+ close_output_file does that for us.
+
+ (new_line_control, create_new_buffer): Use "foo *p = xmalloc

+ (get_new_buffer): Use O(1) algorithm for resizing a buffer
+ to a much larger size, instead of an O(N) algorithm.
+
+ (process_regexp): Use plain NULL rather than casted 0.
+
+ (make_filename): Use %u, not %d, to format unsigned file number.
+
+ (new_control_record): Use xrealloc exclusively, since it handles
+ NULL reliably.
+
+ (extract_regexp): Change misspelled word in diagnostic.
+
+ (get_format_width): Even if a minimum field width is specified,
+ allow room for enough octal digits to represent the value of
+ the maximum representible integer. This fixes a potential
+ buffer overrun. Calculate this room at compile-time, not
+ at run-time; this removes the need for bytes_to_octal_digits.
+ Check for overflow; this removes a FIXME.
+
+ (get_format_prec): Don't allow precision to be signed; it's
+ not ANSI. Check for overflow. Remove hardcoded "11" as
+ default precision; this fixes a potential buffer overrun
+ on hosts with wider size_t.
+
+ (get_format_conv_type): Change local variable to be of type
+ unsigned char, not int; this removes a potential subscript
+ violation on hosts where char is signed.
+
+ (max_out): Replace "for (;*p;)" with more-standard "while (*p)".
+ Allow "%%" in format. Don't overflow when
+ counting lots of percents.
+
+ (usage): Default sprintf format is %02u, not %d.

+2003-09-07 Jim Meyering <jim@meyering.net>

+
+ * tests/misc/tty-eof: Write ^D as \cD.
+ Complete the change of 2003-08-02.
+
+ * Makefile.maint (po-check): Use cvsu, so that a temporary source

+
+2003-09-06 Jim Meyering <jim@meyering.net>

+ * src/tail.c (struct linebuffer, struct charbuffer): Likewise.

+
+ Standardize on BUFSIZ as opposed to other macro names and values.
+ * src/head.c (BUFSIZE): Remove. All uses changed to BUFSIZ.

+ (tab): Now int, not char. Initialize to TAB_DEFAULT.
+ (specify_sort_size): If multiple sizes are specified, use the largest.
+ (begfield, limfield): Support NUL tab char.
+ (set_ordering): Do not let -i override -d.
+ (main): Report an error if incompatible -o or -t options are given.

+
+2003-09-03 Jim Meyering <jim@meyering.net>
+
+ * src/du.c (AUTHORS): Remove Larry McVoy's name, since the relatively

+
+2003-08-22 Lawrence Teo <lcteo@uncc.edu>
+
+ * src/md5sum.c (split_3): Accept the BSD format for generic

+ formats since these are the two algorithms presently used in
+ coreutils. Updated comments to reflect this change.
+ (bsd_split_3): Updated comments.
+
+ * tests/md5sum/basic-1: New test to make sure that
+ `md5sum --check' doesn't accept the BSD SHA1 format (adapted
+ from `check-bsd' test in tests/sha1sum/basic-1).
+
+ * tests/sha1sum/basic-1 (check-bsd2, check-bsd3): New tests for

+
+2003-08-30 Jim Meyering <jim@meyering.net>
+
+ * src/ln.c (do_link): Use SAME_INODE rather than open-coding it.
+
+ When source and destination arguments refer to the same file, reside
+ on a partition (e.g. VFAT) on which distinct names may refer to the
+ same directory entry (often due to variations in case), and when the
+ link count for the file is 1, mv no longer unlinks the file. Instead,
+ it gives the expected diagnostic that the source and destination are
+ the same. WARNING: this is an incomplete fix. If the file happens
+ to have a link count of 2 or greater, such an erroneous mv command
+ will still unlink it.
+ Although that is not possible on vfat or umsdos, it is possible on
+ other file system types, e.g., ntfs, and hpfs.
+ * src/copy.c (same_file_ok): Invoke same_name (which might still
+ return false for names that refer to the same directory entry)
+ only if the link count is 2 or more.
+ * tests/mv/vfat: Show how to demonstrate the above problem.
+ This test is not run.

+
+ * src/paste.c (paste_parallel): Don't output `EOF' (aka -1) as a `char'.
+ This would happen for nonempty files not ending with a newline.

+ This fixes a typo I introduced in who-users.c on 1996-02-23.
+
+ * Makefile.maint (makefile-check): Add 0-9 to the range of characters

+
+ * man/Makefile.am (.x.1): Ensure that generated PROGRAM.1 files
+ are read-only.
+
+ * src/tail.c (tail_lines): Fix a potential (but very hard to exercise)
+ race condition bug. The bug would be triggered when tailing a file
+ with file pointer not at beginning of file, and where the file was
+ truncated to have a length of less than the initial offset at just
+ the right moment (between the two lseek calls in this function).
+
+ An invalid initial value for *read_pos would result in
+ `tail -n0 -f FILE' and `tail -c0 -f FILE' doing what amounted to a
+ busy-wait rather than sleeping between iterations. The bug manifests
+ itself only when tailing regular files that are initially nonempty.
+ * src/tail.c (tail_bytes): Set *read_pos to new file offset after

+
+2003-08-10 Jim Meyering <jim@meyering.net>
+

+
+ Merge getline from gnulib.
+ * lib/getline.h, lib/getline.c, m4/getline.m4: Merge from gnulib.

+ * m4/jm-macros.m4 (jm_MACROS): Use gl_GETNDELIM2 rather than
+ checking for getdelim.

+ * src/cut.c: Include getndelim2.h rather than getdelim2.h.
+ (cut_fields): Invoke getndelim2 rather than getdelim2.
+
+2003-08-04 Jim Meyering <jim@meyering.net>
+
+ * src/sort.c (main): Use unsigned int instead of int for `nsigs'
+ and for the indices to iterate through nsigs.
+
+2003-08-02 Paul Eggert <eggert@twinsun.com>
+
+ * src/sort.c: Minor code cleanups, mostly to use more accurate
+ types and to remove unnecessary casts.
+ (min, max): Remove. All uses changed to MIN and MAX.
+ (hard_lc_collate, hard_LC_TIME, struct buffer.eof, struct
+ keyfield.skipsblanks, struct keyfield.skipeblanks, struct
+ keyfield.numeric, struct keyfield.general_numeric, struct

+ (struct keyfield.ignore): Now bool const *, not int *.
+ (struct keyfield.translate): Now char const *, not char *.
+ (struct month.name): Likewise.

+ (fillbuf): Return bool, not int. All uses changed.
+ (fillbuf, keycompare, new_key, main):
+ Use SIZE_MAX rather than (size_t) -1.
+ (trailing_blanks): Renamed from trim_trailing_blanks.
+ Return the number of blanks to trim. All uses changed.
+ (getmonth): Use trailing_blanks rather than open code.
+ (keycompare): Do not cast char * to unsigned char *; not needed.
+ CMP_WITH_IGNORE converts args to UCHAR, so no need to convert it
+ ourselves.
+ (compare, main): Use | rather than || to avoid jumps.
+ Replace "diff = NONZERO (alen)" with "diff = 1", since alen must
+ be nonzero there.
+ (check, first_same_file, sort, main):
+ Use bool instead of int local vars when possible.
+ (check): Merge the old 'checkfp' and 'check' into a single function,
+ that returns a boolean (true if the file was ordered).
+ All uses changed.
+ (main): Use int instead of unsigned for iterating through nsigs.
+ Rename local var "posix_pedantic" to "posixly_correct".
+
+2003-08-02 Jim Meyering <jim@meyering.net>
+
+ * src/nice.c [!NICE_PRIORITY]: Include <time.h> before <sys/resource.h>
+ to avoid compilation error on Ultrix. Reported by Christian Krackowizer.
+
+ * src/cut.c (cut_fields): Don't read again after encountering an
+ initial EOF. E.g., `cut -f2' would do so.
+ * tests/misc/tty-eof: Add a test for the above fix.
+
+ * src/sort.c (sortlines): Add description and references.
+ From Paul Eggert.
+

+ Reported by Christian Krackowizer.
+
+2003-07-31 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS: Add --rfc-2822 option to GNU date.

+
+2003-08-01 Jim Meyering <jim@meyering.net>
+
+ * tests/shred/remove: Ensure that $? is 0 for the final `exit 0'.
+ Otherwise, with at least the /bin/sh from HPUX 10.20,
+ the trap code would end up converting that to exit 1 and thus an
+ unexpected test failure. Reported by Christian Krackowizer.
+
+2003-07-31 Paul Eggert <eggert@twinsun.com>
+
+ * src/ptx.c: Do not include bumpalloc.h.
+ (WORD_TABLE): New member alloc.
+ (ALLOC_NEW_WORD): Remove.

+ bumpalloc primitives.
+
+2003-07-29 Jim Meyering <jim@meyering.net>
+
+ * Version 5.0.90.
+
+ * README: When running tests as root, suggest using
+ sudo with NON_ROOT_USERNAME=$USER.
+
+ * tests/Makefile.am (all_programs): Makefile is in ../src, not

+
+2003-07-28 Jim Meyering <jim@meyering.net>
+
+ * Makefile.maint (GZIP_ENV): Try Debian/gzip's new --rsyncable option.
+
+2003-07-28 Paul Eggert <eggert@twinsun.com>
+
+ * lib/stdbool.hin (_Bool): Make it signed char, instead of
+ an enum type, so that it's guaranteed to promote to int.
+ * src/sort.c (sortlines_temp): Undo previous change.
+
+2003-07-28 Jim Meyering <jim@meyering.net>
+
+ * src/sort.c (sortlines_temp): Declare local `swap' to be `int', not
+ `bool'. Otherwise, at least one buggy compiler (alpha gcc-2.95.4)
+ would cause lines[-1 - swap] (with swap = false) to evaluate to
+ lines[4294967295].
+
+2003-07-27 Jim Meyering <jim@meyering.net>
+
+ * tests/priv-check (my_uid): Use `!', not `^' in case pattern `[!0-9]',
+ since /bin/sh of at least NetBSD 1.6 and OpenBSD 3.2 don't accept `^'.
+
+ * src/remove.c (prompt) [! recursive]: Don't prompt about unwritable
+ directories, as required by POSIX. Reported by Karl Berry.
+ * tests/rm/dir-no-w: New file. Test for the above fix.
+ * tests/rm/Makefile.am (TESTS): Add dir-no-w.
+
+ * tests/mk-script: Emit `$xx', not its expansion.
+
+2003-07-27 Paul Eggert <eggert@twinsun.com>
+
+ This change was inspired by a similar proposal by Stepan Kasal.
+ * src/sort.c (mergelines, sortlines_temp): New functions.
+ (sortlines): Use them, to reduce the number of times that
+ we need to copy 'struct line' values. This improved CPU
+ performance by about 30% on one 18 MB test.
+ (sort): Don't invoke sortlines unless we have 2 or more lines.
+
+2003-07-26 Stepan Kasal <kasal@ucw.cz>
+
+ * src/sort.c (sort): Don't require two `struct line's per text line,
+ the new sort algorithm requires just 1.5.
+
+2003-07-27 Jim Meyering <jim@meyering.net>
+
+ * src/pathchk.c (validate_path): Use %lu, not %ld.
+ From Paul Eggert.
+ * src/cut.c (is_printable_field): Simplify bit arithmetic.
+ From Paul Eggert.
+ * src/ls.c (sort_files): Put `volatile' in the right place.
+ From Paul Eggert.
+
+2003-07-26 Jim Meyering <jim@meyering.net>
+
+ Use only one bit per field/offset in array, not one `int'.
+ * src/cut.c (printable_field): Change type to `unsigned char'.
+ (mark_printable_field, is_printable_field): New functions.
+ Use them in place of all direct accesses of `printable_field'.
+
+ * src/expand.c (parse_tabstops): Detect overflow properly.
+ * src/cut.c (set_fields): Likewise.
+
+ * src/rm.c: Include "dirname.h".
+ (usage): Use base_name (program_name) in body of --help output.
+ This lets me...
+ * man/Makefile.am (.x.1): ...back out the kludge of 2003-07-22.
+ Idea from Brendan O'Dea, who suggested using
+ `program_name = basename (argv[0]);' everywhere --
+ can't do that, but using base_name works just fine here.
+
+ * src/Makefile.am (AM_INSTALLCHECK_STD_OPTIONS_EXEMPT): Exempt test.
+
+2003-07-24 Paul Eggert <eggert@twinsun.com>
+
+ Fix some POSIX-compliance problems with 'test'. This makes
+ 'test' more compatible with Bash.
+
+ * NEWS, doc/coreutils.texi: Document the following.
+ * src/test.c: Include exitfail.h.
+ (TEST_FAILURE): New constant, used for exit status if 'test' fails.
+ (test-syntax_error): Use it.
+ (binary_operator): Now takes bool arg specifying whether left operand
+ is -l ARG, so that caller determines this rather than us.
+ All uses changed.
+ (term): Use posixtest to evaluate parenthesized subexpressions.
+ (unary_operator, one_argument): Remove support for -t without operand.
+ (one_argument): Take argument from argv[pos].
+ (one_argument, two_arguments, three_arguments): Advance pos.
+ All callers changed.
+ (three_arguments): Look for binary ops before "!". Then look
+ for parenthesized one_argument expressions, instead of trusting
+ expr () to do the right thing.
+ (posixtest): Now takes number of args. All callers changed.
+ Treat "( A B )" like "A B".
+ (main): Set exit_failure to TEST_FAILURE. Don't depend on
+ POSIXLY_CORRECT, as we now conform to POSIX by default.
+ (main) [!LBRACKET]: Do not recognize "--help" or "--verbose" unless.
+ * tests/test/Test.pm (test_vector): Add several tests to check
+ the above. Syntax errors now exit with status 2, not 1.
+ * man/Makefile.am (mapped_name): Use `../src/[' binary to create test.1.
+
+2003-07-26 Jim Meyering <jim@meyering.net>
+
+ * tests/help-version: Adjust for above change in test behavior:
+ `[' exits with 2, not 1, and test doesn't accept --help or --version.
+
+ * Makefile.maint (ME): Don't use trick suggested in Make manual.
+ It doesn't work for make-3.79.1. Reported by Christian Krackowizer.
+
+ * Makefile.maint (sc_system_h_headers): Another syntax check.
+ (syntax-check-rules): Add it to the list.
+
+ * src/pathchk.c (validate_path): Cast strlen value to `unsigned long'
+ so it matches `%ld' format even on 32-bit systems.
+
+ * src/fmt.c (flush_paragraph): Cast field width to `int' to
+ avoid warning on 64-bit systems.
+
+ * src/ls.c (sort_files): Make `func' volatile, so it can't be
+ clobbered by a `longjmp' into this function.
+
+2003-07-25 Jim Meyering <jim@meyering.net>
+
+ * src/pathchk.c (validate_path): Use %ld format (not %d) for size_t
+ value.
+
+ * tests/misc/split-fail: Disable the --line-bytes=$_4gb test,
+ because it'd evoke spurious failure on 64-bit systems.
+
+2003-07-24 Jim Meyering <jim@meyering.net>
+
+ * src/dd.c (usage): Document the fact that SIGUSR1 makes dd
+ output its current record counts. Reported by Jurriaan.
+
+ * tests/wc/Test.pm (test_vector): Disable the `PIPE' tests when running
+ `wc' with no options. This goes along with the change of 2003-07-20.

+
+ Begin to address this comment: What if someone wants to
+ extract the 1,000,000-th field of some huge input file?
+ The first step is to rearrange things so that the values
+ in the printable_field array are all 0/1 rather than 0/1/2.
+ * src/cut.c (RANGE_START_SENTINEL): Remove.
+ Store range-start indices in a hash table, rather than

+ (range_start_ht): New global.
+ (hash_int, hash_compare_ints, is_range_start_index): New functions.

+
+2003-07-20 Paul Eggert <eggert@twinsun.com>

+2003-07-20 Jim Meyering <jim@meyering.net>
+
+ * Makefile.maint (sc_changelog): Add another nit-picky check.

+
+ * NEWS: Document this.
+ * doc/coreutils.texi (wc invocation): Likewise.

+ Do not worry about POSIXLY_CORRECT.
+ Use null file, not empty-string file, to denote stdin,
+ since "" is a valid file name on some hosts.

+ * tests/cp/fail-perm: Use $srcdir/../priv-check, rather than
+ hard-coding something not quite equivalent.
+ Paul Jarc reported the inconsistent diagnostics.
+
+ * src/sort.c (main): Use close_stdout via atexit.
+ Now `sort --version' and `sort --help' fail, as they should
+ when their output is redirected to /dev/full.
+
+ * src/su.c (usage): Don't call close_stdout here.
+ (main): Use close_stdout via atexit.
+ Now `su --version > /dev/full' fails, as it should.
+ Somehow, the change of 2000-05-07 that purports to fix this
+ was not checked in.
+
+ * tests/help-version (--help/--version vs. /dev/full): Special-case

+ Reported by Clement Wang.
+ * tests/uniq/Test.pm (101, 102): Update tests of -c accordingly.
+
+ * tests/expr/basic: Add tests for when exit status is 2.

+ (main): Initialize exit_failure to EXPR_ERROR.
+ Exit with EXPR_INVALID on syntax error (too few arguments).
+ (nextarg): Use strcmp, not strcoll; strcoll might return

+ (docolon, eval4, eval3): Exit with status 3 on invalid argument type
+ or other such error.
+ (eval2): Report an error if strcoll fails in a string comparison.

+ per GNU maintainer guidelines. The next non-beta release will be 5.1.
+
+ This script would have caught at least two recent bugs:
+ those in [ and kill.
+ * tests/help-version: Revive this script.
+ It wasn't doing anything useful, since $all_programs wasn't being
+ defined by the invoking Makefile.am.
+ Reflect that nohup is no longer a script, so don't exclude it.
+ Add framework to handle the programs added since it was last run:
+ kill, stat, unlink, [, link, readlink.
+ Fix path-related problems deriving from the move of this script
+ from src/ to its present location.
+ * tests/Makefile.am (all_programs): Define.
+ (TESTS_ENVIRONMENT): Use it.
+
+ * src/kill.c (main): Fix bug introduced on 2003-05-10 (for 5.0.1)
+ whereby kill would always attempt to operate on argv[0] and fail.
+
+ * src/test.c (integer_expected_error): Improve diagnostic -- now,
+ it also matches the one from bash's builtin test.
+ (binary_operator): Add \n at end of diagnostic.
+
+ * tests/rm/fail-2eperm: Remove setuidgid-related code. Move it to ...
+ * tests/priv-check: Move setuidgid-related and
+ NON_ROOT_USERNAME-checking code to this file.

+ * README: Update section on testing as `root'.
+ Suggestion from Paul Jarc.
+
+ * src/test.c (AUTHORS): Replace 3-letter usernames with the actual
+ names of authors that I just found in bash's builtins/test.def.
+
+ Running `[' with no arguments would evoke a segfault.
+ * src/test.c (main) [LBRACKET]: Move initialization of argv to

+
+ * src/Makefile.am (AM_CPPFLAGS): Rename from `INCLUDES', to avoid

+
+2003-07-15 Jim Meyering <jim@meyering.net>
+
+ * Version 5.0.1.
+
+ * Makefile.maint (%.asc): Remove target first, so gpg doesn't

+
+ * configure.ac: Remove uses of OPTIONAL_BIN_ZCRIPTS and last

+
+ * src/Makefile.am (bin_SCRIPTS): Remove use of just-removed
+ $(OPTIONAL_BIN_ZCRIPTS).
+
+ * src/Makefile.am (localedir.h): Put the `2>&1' after the redirect
+ target, not before the `>'.
+
+ * src/remove.c (remove_dir): Give a diagnostic upon failed save_cwd,
+ now that that function no longer calls `error'.
+
+ * src/df.c (find_mount_point): Emit a diagnostic for each
+ failed syscall, rather than relying on caller to do that.
+ The caller couldn't do a good job, anyhow -- too many different
+ ways to fail (each with a different referent).
+ Give a diagnostic upon failed save_cwd, now that that function
+ no longer calls `error'.
+ (show_point): Don't diagnose find_mount_point's errors, now that
+ it handles them itself.
+
+ * src/df.c (find_mount_point): Don't let free clobber errno upon
+ failed chdir.
+
+ * src/sys2.h: Remove alloca-related block.
+ * src/system.h: Include <alloca.h> here, instead.
+
+ It appears that the `#pragma alloca' included via "system.h" is
+ adequate, since join.c uses alloca, yet lacked an in-file #pragma.
+ * src/copy.c, src/cp.c, src/df.c, src/install.c, src/ln.c:
+ * src/ls.c, src/mv.c, src/remove.c: Remove `#pragma alloca'.
+
+ * src/chown-core.c (change_file_owner): Do not restore any special
+ permission bits (e.g., set-user-ID, set-group-ID) that are reset
+ by chown(2) on some systems. Suggestion and insistence :-) from
+ Michael Stone.
+
+ * tests/input-tty: Also check `test -t 1'.
+ This is necessary on linux-2.4.21. Otherwise, the stty/basic-1
+ test would block when run in the background.
+
+2003-07-11 Jim Meyering <jim@meyering.net>
+
+ * tests/sample-test: Also fail if cat-to-create-expected-output
+ fails. Otherwise, if both `exp' and `out' were to end up empty
+ because of e.g., a full disk, they would mistakenly compare equal.
+
+ * src/nohup.c: New file. Rewrite of nohup.sh in C.
+ This solves a portability problem: on at least Solaris systems,
+ when nohup.sh used the vendor /bin/sh, it would exit with status
+ of `1' rather than the required 126 or 127 upon failure to exec
+ the specified program.
+
+ * src/Makefile.am (EXTRA_SCRIPTS): Remove definition.
+ (bin_PROGRAMS): Add nohup.
+ (EXTRA_DIST): Remove nohup.sh.

+ * man/Makefile.am (nohup.1): Depend on nohup.c, rather than nohup.sh.
+
+ * tests/misc/nohup: Tests for the above.
+ * tests/misc/Makefile.am (TESTS): Add nohup.
+
+ * src/head.c (diagnose_copy_fd_failure): New function, renamed from
+ the macro, COPY_FD_DIAGNOSE.
+ (diagnose_copy_fd_failure): Enclose diagnostic in _(...).
+ (head_file): Likewise.
+
+ * src/date.c: Include "quote.h".
+ (batch_convert): Use the quote function rather than using literal `...'
+ in a diagnostic.

+2003-07-10 Jim Meyering <jim@meyering.net>
+
+ * src/head.c (usage): Use 1024*1024 in place of 1048576.
+ * src/tail.c (usage): Likewise.
+
+ * tests/rm/fail-2eperm: Now that we have setuidgid, use it in
+ place of the kludge in this test. Suggestion from Paul Jarc.
+
+ * src/Makefile.am (noinst_PROGRAMS): Define to setuidgid.
+ * src/setuidgid.c: New program, solely for testing (not installed).
+
+ * src/chown-core.c (change_file_owner): Don't leak file descriptors
+ when dereferencing symlinks.
+
+2003-07-09 Jim Meyering <jim@meyering.net>
+
+ * tests/du/slash: New file/test for today's lib/ftw.c fix.
+ * tests/du/Makefile.am (TESTS): Add slash

+ from function returning non-void''.
+
+2003-07-08 Jim Meyering <jim@meyering.net>
+
+ * man/help2man: Update to version 1.29.
+
+ * man/help2man: Add END handler to close STDOUT and check for errors.
+
+2003-06-30 Paul Eggert <eggert@twinsun.com>
+
+ Add support for a "[" that conforms to the GNU coding standards,
+ i.e., that does not depend on its name.
+ * src/lbracket.c: New file.
+ * README: Add "[".
+ * man/Makefile.am (programs): Ignore "[", since it doesn't have
+ a separate man page.
+ * src/Makefile.am (bin_PROGRAMS): Add "[".
+ (__SOURCES): New var.
+ * src/test.c (LBRACKET): Define to 0 if not defined.
+ (main): Use LBRACKET rather than argv[0].
+
+ * src/test.c (one_argument): Do not check for -t if POSIXLY_CORRECT.
+ Reported by Paul Jarc and Dan Jacobson.
+
+ * src/test.c (main): Do not recognize --help or --version if
+ POSIXLY_CORRECT, when invoked as "test". Handle "[ ]" correctly.
+ Do not bother testing that margv[margc] is non-null.
+
+2003-07-04 Jim Meyering <jim@meyering.net>
+
+ * src/who.c (print_line): Rewrite to use asprintf, in order to be
+ able to avoid emitting trailing spaces. Reported by Dan Jacobson.
+
+ * tests/misc/head-elide-tail: Add tests of head's new --lines=-N
+ option, and perform the +1600 invocations of head IFF the envvar
+ RUN_EXPENSIVE_TESTS is set.
+
+2003-07-03 Jim Meyering <jim@meyering.net>
+
+ * src/cp.c (do_copy): Give a better diagnostic when failing due
+ to nonexistent destination directory. Reported by Dmitry Rutsky.
+ See http://bugs.debian.org/199730 for details.
+
+2003-06-27 Jim Meyering <jim@meyering.net>
+
+ split's --verbose option did nothing [broken in 4.5.10 and 5.0]
+ * src/split.c (longopts): Use `1', not `0' as the value for
+ for &verbose. Reported by Keith Thompson.
+
+ Test for the above fix.
+ * tests/misc/split-a: Also use --verbose and compare stderr
+ output with what we'd expect.
+
+2003-06-20 Jim Meyering <jim@meyering.net>
+
+ * src/copy.c (copy_internal) [HAVE_STRUCT_STAT_ST_AUTHOR]:
+ Use `error_t' (rather than int) as type for local `err'.
+ From Alfred M. Szmidt.
+
+2003-06-19 Marcus Brinkmann <marcus@gnu.org>
+
+ * src/copy.c (copy_internal) [HAVE_STRUCT_STAT_ST_AUTHOR]:

+
+2003-06-19 Jim Meyering <jim@meyering.net>
+
+ * src/ln.c (ENABLE_HARD_LINK_TO_SYMLINK_WARNING): Define to 0.
+ (do_link): Don't warn about hard link to symlink.
+
+2003-06-18 Jim Meyering <jim@meyering.net>
+
+ * src/cut.c: Include "getdelim2.h", not "getstr.h".
+ Reflect renaming: getstr -> getdelim2.
+
+ * src/comm.c, src/join.c, src/nl.c, src/uniq.c: Reflect renaming:
+ readline -> readlinebuffer.
+
+2003-06-09 John David Anglin <dave.anglin@nrc-cnrc.gc.ca>
+
+ * src/readlink.c: Include <sys/types.h> before system.h (because
+ the latter includes <sys/stat.h>). Required on Ultrix 4.3.
+
+2003-06-17 Jim Meyering <jim@meyering.net>
+
+ * src/system.h (initialize_main): Define.
+ Use it in every `main'. Applied via this:
+ p='initialize_main (&argc, &argv);'
+ perl -ni -e '/program_name.=.argv.0/ and print " '"$p"'\n"; print' \
+ $(grep -l program_name.=.argv.0 *.c)
+ test.c uses margc/margv, so I made the change manually for that file.
+ Based on a patch from Bernard Giroud.
+
+2003-06-09 John David Anglin <dave.anglin@nrc-cnrc.gc.ca>
+
+ Fix for build failure on Ultrix 4.3.
+ * src/stat.c: Include sys/statvfs.h in preference to sys/vfs.h.

+
+2003-06-16 Jim Meyering <jim@meyering.net>
+
+ * src/touch.c (O_NDELAY, O_NONBLOCK, O_NOCTTY, EISDIR): Remove
+ definitions.
+ * src/system.h (O_NDELAY, O_NONBLOCK, O_NOCTTY, EISDIR): Define

+
+ * src/cat.c (cat): Remove `#ifndef ENOSYS', now that it's
+ guaranteed to be defined.
+ * src/system.h (ENOSYS, ENOTSUP): Define to -1 if not defined.
+
+ * README: Mention the CVS repository.
+ Encourage addition of test cases.
+
+2003-06-12 Jim Meyering <jim@meyering.net>
+
+ * src/touch.c (touch): Call close only if necessary.
+ From Bruno Haible.
+
+ * src/wc.c (usage): Correct wording: wc prints counts in the order
+ `newline, word, byte'. Reported by Keith M. Briggs.
+ * man/wc.x: Fix it here, too. And change `lines' to `newlines'.
+
+2003-06-10 Jim Meyering <jim@meyering.net>
+
+ * tests/date/Test.pm: Add a test for the new format, e.g., May-23-2003.
+
+2003-06-07 Jim Meyering <jim@meyering.net>
+
+ * Makefile.maint (syntax-check): Add commented-out (over-aggressive)
+ rule.
+
+2003-06-06 Jim Meyering <jim@meyering.net>
+
+ * src/extract-magic (main): Avoid newer 3-arg form of open,
+ so this script works also with e.g., perl5.005_03.
+ Patch by John David Anglin.
+
+2003-06-04 Paul Eggert <eggert@twinsun.com>
+
+ * src/system.h: Include <stdbool.h> unconditionally.
+
+2003-06-04 Jim Meyering <jim@meyering.net>
+

+ from check-programs-vs-1. Adjust rule to check for the
+ primary (.x) file, not the generated one (.1).
+
+2003-06-03 Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>
+
+ * man/kill.x: New file.
+ * man/Makefile.am (dist_man_MANS): Add kill.1.
+ (kill.1): New rule.
+
+2003-06-04 Jim Meyering <jim@meyering.net>
+
+ Ensure that the .x file for a new program is never forgotten again.
+ * man/Makefile.am (programs): Define.
+ (check-programs-vs-1): New phony target.
+ (check-local): Depend on it.
+
+2003-06-03 Jim Meyering <jim@meyering.net>
+
+ Avoid unnecessary copying of environment.
+ * src/env.c (main): Rather than clearing the environment and --
+ unless told to ignore environment -- copying all settings from
+ the saved, original environment, clear the environment only when
+ that is requested. Suggested by Jens Elkner.
+
+2003-06-02 Jim Meyering <jim@meyering.net>
+
+ * src/system.h: Always include <string.h>, since we assume C89.

+ * src/tail.c (file_lines): Add new parameter, *read_pos, and set it.
+ (pipe_lines, pipe_bytes, start_bytes, start_lines): Likewise.
+ (tail_bytes, tail_lines, tail): Likewise.

+ rather than stats.st_size from the fstat call.
+
+2003-05-28 Jim Meyering <jim@meyering.net>
+
+ * src/extract-magic: Allow expansion of `$file' in the here-
+ document corresponding to the comment at the top of fs.h.
+
+2003-05-26 Jim Meyering <jim@meyering.net>
+
+ * src/stat.c: Fix portability problem on FreeBSD5.0: don't include

+
+2003-05-21 Jim Meyering <jim@meyering.net>
+
+ * src/head.c (elide_tail_lines_pipe): Fix a thinko.

+ * tests/du/Makefile.am (TESTS): Add fd-leak.
+
+ * src/head.c (AUTHORS): Enclose string in N_(...), now that it

+
+ * src/dd.c (usage): Don't use `,' as the thousands separator
+ in e.g. 1,000,000 and 1,048,576. Instead, do this:

+
+ Fix uniq to conform to POSIX, which requires that "uniq -d -u"
+ must output nothing. Problem reported by Josh Hyman.
+
+ * src/uniq.c (enum output_mode, mode): Remove, replacing with:
+ (output_unique, output_first_repeated, output_later_repeated):
+ New vars. All uses of "mode" changed to use these variables,
+ which are not mutually exclusive as "mode" was.
+ (writeline): New arg "match", used to control whether to
+ obey output_first_repeated or output_later_repeated.
+ All callers changed.
+ (check_file, main): Adjust to above changes.
+
+ * tests/uniq/Test.pm: Test that 'uniq -d -u' outputs nothing.
+
+2003-05-14 Jim Meyering <jim@meyering.net>
+
+ * tests/rm/rm3: Use tr's \n notation rather than \012.

+ * src/readlink.c (main): Set program_name before first use.
+ Remove that (redundant) first use.
+ Don't exit successfully just because --verbose was specified.
+ Pass 0, not EXIT_SUCCESS, as first argument to error; when that

+
+ * src/uname.c (main): When failing due to too many arguments, also say
+ that, rather than just "Try `uname --help' for more information.".
+ * src/comm.c (main): Likewise, but for too few arguments.

+
+ Implement support so that `head --lines=-N' works on seekable files.
+ * src/head.c (enum Copy_fd_status): Define.

+ (elide_tail_lines_file): Call it here.
+
+2003-05-06 Jim Meyering <jim@meyering.net>
+

+
+2003-05-04 Jim Meyering <jim@meyering.net>
+
+ * tests/head/Test.pm: Remove tests of --bytes=-N; using that framework

+
+2003-05-04 Paul Eggert <eggert@twinsun.com>

+
+2003-05-03 Jim Meyering <jim@meyering.net>
+
+ Extend head to accept --lines=-N (--bytes=-N) and to print all
+ but the N lines (bytes) at the end of the file.
+ * src/head.c: Include full-write.h, full-read.h, inttostr.h, quote.h.
+ Use quote() in diagnostics, rather than literal `' marks.
+ (copy_fd, elide_tail_bytes_pipe, elide_tail_bytes_file):

+ Handle negative line and byte counts.
+ * tests/head/Test.pm: Add lots of tests to exercise --bytes=-N.
+
+ * tests/du/8gb: Skip test if the file system of `.' doesn't support

+ has two components.
+
+ * src/tail.c:
+ Change type of n_units, n_bytes, n_lines to be `uintmax_t'.
+ (dump_remainder): Move two declarations `down' into the scope

+ (xlseek): Return the resulting offset.
+ (file_lines): Rename parameter, file_length, to end_pos.
+ (pipe_lines): Don't coerce safe_read return value to `int'.
+ Adapt tests accordingly.
+ (pipe_bytes) [struct charbuffer] (nbytes): Change type from `int'
+ to `unsigned int'.
+ Change type of `total_bytes' from `int' to `size_t',
+ since the former wouldn't always be wide enough.
+ Don't coerce safe_read return value to `int',
+ and adapt tests accordingly.
+ Now that testing for a read error no longer involves

+ (tail_bytes): Now that `n_bytes' may be larger than
+ OFF_T_MAX, test for that condition and, if it's true, don't
+ use lseek optimizations.
+ (parse_options): Don't fail just because N_UNITS is larger than
+ the maximum size of a file -- tail may be applied to an input
+ stream (e.g., a pipe) with more data than that.
+
+ * Makefile.maint (syntax-check): Rename from alloc-check.
+ Also check for SPACE-TAB sequences.
+ Also check for malloc/calloc/realloc casts.

+ * src/tsort.c (tsort): Remove unnecessary test of have_read_stdin.
+ (main): Minor syntactic clean-up.
+
+ * src/tsort.c (tsort): Fail if the input contains an odd number of

+2003-04-20 Paul Eggert <eggert@twinsun.com>
+
+ Fix printf POSIX compatibility bug reported by Ben Harris in
+ <http://mail.gnu.org/archive/html/bug-coreutils/2003-04/msg00070.html>.
+ * doc/coreutils.texi (printf invocation): It's \NNN in the format,
+ \0NNN in the %b operand.
+ * src/printf.c (usage): Likewise.
+ (print_esc): New arg OCTAL0 to specify whether \0NNN or \NNN
+ is desired. All uses changed. Behave like Bash printf if %b
+ operand uses \NNN where the initial N is not 0.
+
+2003-04-17 Jim Meyering <jim@meyering.net>
+
+ * src/stty.c: Remove uses of PROTOTYPE macro.
+
+2003-04-15 Jim Meyering <jim@meyering.net>
+
+ * Makefile.maint: Remove (or replace-with-TAB(s) to retain alignment)
+ each sequence of spaces before a TAB character.
+
+2003-04-13 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (is_empty_dir): Don't closedir (NULL).
+
+2003-04-12 Jim Meyering <jim@meyering.net>
+
+ Giving nl an invalid STYLE argument (in --header-numbering=STYLE (-h),
+ --body-numbering=STYLE (-b), or --footer-numbering=STYLE (-f)) or
+ FORMAT (--number-format=FORMAT (-n)) would not give a useful diagnostic.
+ * src/nl.c (main): Fix those problems and remove literal quote marks
+ (e.g., "`%s'") from format string; instead use "%s" in each format
+ string and `quote (optarg)' as the corresponding argument.
+ Also, diagnose all invalid command line options before failing.
+
+ * src/nl.c (proc_text): Fix a bug that would make nl output extra
+ newlines in some cases. Details here: http://bugs.debian.org/177256.
+ This bug was introduced on 2001-11-10 for textutils-2.0.17.
+ * tests/misc/nl: Add test for the above-fixed bug.

+
+2003-04-10 Jim Meyering <jim@meyering.net>
+
+ * src/stty.c (wrapf): Declare with format attribute.
+
+ The S_MAGIC_... names shouldn't be maintained in two places (prior
+ to this change, one would have to keep stat.c and fs.h in sync).
+ This change makes it so those names and the corresponding
+ hexadecimal constants all reside in stat.c. fs.h is now generated.
+ * src/Makefile.am (fs.h): New rule to generate fs.h from stat.c.
+ (BUILT_SOURCES): Add fs.h, now that it's generated.
+ (EXTRA_DIST): Add extract-magic.
+ * src/extract-magic: New script to extract fs.h definitions from stat.c.
+ * src/stat.c (human_fstype) [__linux__]: Append each hex constant from
+ fs.h in a comment after the corresponding `case S_MAGIC_...:' statement.
+
+ * tests/tail-2/big-4gb: Skip this test (don't fail) if creating a
+ file with nominal length > 4GB fails. Reported by Michael Deutschmann.
+
+ * man/unexpand.x: Add `SEE ALSO' reference to expand.
+ * man/expand.x: Add `SEE ALSO' reference to unexpand.

+ (main): Check for overflow in obsolescent line count option.
+
+2003-04-09 Jim Meyering <jim@meyering.net>
+
+ * tests/misc/split-fail: Add a new test for the above fix.
+
+ * src/split.c (bytes_split): Use size_t temporary (rather than
+ uintmax_t original) in remaining computations. From Paul Eggert.
+
+ Handle command line option arguments larger than 2^31.
+ This allows e.g., splitting into files of size 2GB and larger,
+ and running split --lines=N with N=2^31 or more.
+ But for --line-bytes=N, the restriction that N <= SIZE_MAX
+ remains (for now), due to the way it is implemented.
+
+ * src/split.c: Include "inttostr.h".
+ (bytes_split, lines_split, line_bytes_split, main):
+ Use uintmax_t, not size_t, for file sizes.
+ (main): Give a better diagnostic for option arguments == 0.
+ Use umaxtostr to print file sizes.
+ Reported by Luke Hassell.
+
+2003-04-08 Jim Meyering <jim@meyering.net>
+
+ * src/rm.c (usage): Mention that --directory (-d) works only

+ * src/kill.c (sys_siglist): Also check for __sys_siglist.
+ Patch by Tony Leneis.
+ * configure.ac: Also check for declaration of __sys_siglist.
+ Required for Tru64 4.0D, 4.0F, and 5.1.
+ Reported by Tony Leneis.
+
+2003-04-04 Jim Meyering <jim@meyering.net>
+
+ * src/Makefile.am (PERL): Remove unnecessary definition.
+
+ Because of inappropriate (but POSIX-mandated) behavior of rename,
+ `mv a b' would not remove `a' in some unusual cases. Work around
+ this by unlinking `a' when necessary.
+
+ * src/copy.c (same_file_ok): Add an output parameter.
+ Set it in the offending case.
+ (copy_internal): When necessary, unlink SRC_PATH and inform caller.
+ Reported by Ed Avis.
+ * tests/mv/hard-4: New test for the above.
+ * tests/mv/Makefile.am (TESTS): Add hard-4.
+
+ Clean up rules for automatically generated sources:
+ * src/Makefile.am (dircolors.h, wheel-size.h, wheel.h, false.c):
+ Make each generated file be read-only.
+ Add each file name to BUILT_SOURCES separately.
+ (MAINTAINERCLEANFILES): Set to $(BUILT_SOURCES).
+
+ Put LOCALEDIR macro definition in new file: localedir.h.
+ * src/Makefile.am (DEFS): Remove definition.
+ (localedir.h): New rule.
+ (BUILT_SOURCES, DISTCLEANFILES): Add localedir.h.
+ * src/system.h: Include "localedir.h".
+
+2003-04-02 Jim Meyering <jim@meyering.net>
+
+ * Version 5.0.
+
+ * tests/misc/Makefile.am (TESTS): Add false.
+
+ * Makefile.maint (TMPDIR): Make sure it's defined.
+ (my-distcheck): Build in $(TMPDIR), not `.'.
+
+ * src/Makefile.am (false.c): Change all occurrences of
+ `(EXIT_SUCCESS)' to `(EXIT_FAILURE)' so that false exits
+ unsuccessfully also with --help. Reported by Paul Jarc,

+2003-03-28 Jim Meyering <jim@meyering.net>
+
+ * tests/stty/row-col-1: Skip this test if stty can't get window size.
+ This happens when connecting to sparc-solaris5.7 via ssh from within
+ emacs. Reported by Karl Berry.
+
+ * tests/du/basic: Use seq, not `yes' to generate 4KB of data.
+ Otherwise, on systems (DJGPP) that emulate pipes using files,
+ this test would never complete, waiting for `yes' to terminate.
+ * tests/du/slink: As above, use seq, not `yes' to generate link target.
+ * tests/rm/hash: As above, use seq, not `yes' to generate dir name.
+ Reported by Rich Dawe.

+2003-03-24 Paul Eggert <eggert@twinsun.com>
+
+ Fix buffer overrun problem reported by TAKAI Kousuke, along
+ with some other POSIX incompatibilities.
+
+ * src/printf.c (print_esc): Do not treat \x specially if
+ POSIXLY_CORRECT. Avoid buffer overrun if the format ends
+ in backslash. Treat incomplete escape sequences as strings
+ of characters, as POSIX requires.
+ (print_formatted): Allow multiple flags. Avoid buffer overrun
+ if the format is incomplete.

+ * TODO: Plan to add an autoconf test to work around the bug.
+
+2003-03-22 Jim Meyering <jim@meyering.net>
+
+ * src/stat.c: Don't include <sys/sysmacros.h>.
+ That is already done via system.h. Otherwise, the multiple
+ inclusion would evoke redefinition warnings from Cray's /bin/cc,
+ aka Cray Standard C Version 4.0.3 (057126) Mar 22 2003 22:02:28.
+ (human_fstype): Factor some directives `up', out of this function.
+ Cast away `const' to avoid error from Cray's /bin/cc.
+
+2003-03-20 Jim Meyering <jim@meyering.net>
+
+ * announce-gen (print_changelog_deltas): Ensure that a newline
+ precedes each row of `*'s.
+
+2003-03-20 Jim Meyering <jim@meyering.net>
+
+ * Version 4.5.11.
+
+ * src/seq.c (valid_format): Also accept ` ' and `'' as valid

+ Do not require that a field width be specified.
+ Do not fail when given a field width of `0'.
+ Reported by Dan Jacobson.
+ * tests/seq/basic: Add new tests for the above-fixed bug.
+
+ * src/Makefile.am (all-local): Append $(EXEEXT) to use of `su'
+ (install-root): Likewise.
+ (install-exec-local): Likewise.
+ Based on a patch from Richard Dawe.
+
+2003-03-19 Jim Meyering <jim@meyering.net>
+
+ * man/Makefile.am (.x.1): Use $(LN_S) instead of 'ln -s',
+ because the DJGPP 2.03 port of 'ln -s' doesn't work.
+ Include $(EXEEXT) in program names.
+ Since $(LN_S) may degenerate to `cp -p', be careful
+ to invoke it from the destination directory.
+ Mostly from Richard Dawe.
+ * configure.ac: Use AC_PROG_LN_S.
+
+ * tests/mv/part-symlink: Unset CDPATH. Otherwise, having the
+ CDPATH shell variable set could cause this test to fail.
+ Reported by Karl Berry.
+
+2003-03-18 Jim Meyering <jim@meyering.net>
+
+ * src/fmt.c [struct Word] (paren, period, punct, final): Change the
+ type of each member from bool <MEMBER>:1 to unsigned int <MEMBER>:1.
+ AIX 5.1's xlc could not compile the former.
+ Patch by Petter Reinholdtsen. Also reported by Mike Jetzer.
+
+2003-03-17 Richard Dawe <rich@phekda.freeserve.co.uk>
+
+ * configure.ac: Include $(EXEEXT) in OPTIONAL_BIN_PROGS'
+ program names, since automake only adds $(EXEEXT) to programs
+ in its *_PROGRAMS.
+
+2003-03-16 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (rm): Put two local variables in static storage,
+ so they can't be clobbered by the potential longjmp.
+
+2003-03-15 Jim Meyering <jim@meyering.net>
+
+ * Makefile.cfg (gnu_rel_host): Fix code to match the comment
+ so that a version number with a two-digit component can still count
+ as an alpha release. Reported by Richard A Downing.
+ (gnu_rel_host): Define in terms of $(RELEASE_TYPE) instead.
+
+2003-03-14 Jim Meyering <jim@meyering.net>
+
+ * src/ansi2knr.c: Remove no-longer-used file.
+ * src/ansi2knr.1: Likewise.
+
+ * Makefile.maint (prev_version_file): Don't use ?= for this particular
+ assignment, since it causes trouble with old versions of GNU make
+ (e.g. 3.76.1). The other uses of `?=' are inoffensive. Details here.
+ http://mail.gnu.org/archive/html/bug-coreutils/2003-03/msg00028.html
+ Patch from Alexandre Duret-Lutz.
+
+ * Use patched automake-1.7.3. Regenerate Makefile.in files in
+ subdirectories so that each includes a definition of ACLOCAL_M4.
+
+ * announce-gen (main): Label the compressed source URLs.
+
+ * Version 4.5.10.
+
+ * tests/du/slink: Relax the test for the `local'ness of a file system,
+ so that now it works also for tmpfs.
+
+ * tests/du/hard-link: Transform output from first du, so that this
+ test doesn't fail on file systems like tmpfs that order directory
+ entries differently.
+
+2003-03-13 Jim Meyering <jim@meyering.net>
+
+ * tests/du/8gb: Work around what appears to be an NFS failure that
+ would make this test fail on some systems.
+
+2003-03-11 Jim Meyering <jim@meyering.net>
+
+ * tests/du/basic: Make the test file exactly 4k bytes long.
+
+ * src/split.c (longopts): Don't hard-code `2' here.
+ Instead, just specify `&verbose', and ...
+ (main): ... remove the `case 2:' block for --verbose.
+
+ * tests/du/basic: Make the test file larger than 64 bytes, so that
+ we don't immediately disqualify file systems (e.g., NetApp) on which
+ smaller files take up zero disk blocks. Reported by Vin Shelton.
+
+2003-03-10 Jim Meyering <jim@meyering.net>
+
+ Don't segfault for a negative field width or precision in format string.
+ Note that this is just a stopgap fix. The longer term solution may
+ involve adapting bash's builtins/printf.def.
+
+ * src/printf.c: (UNSPECIFIED): Define.
+ (print_direc): Use the special value, UNSPECIFIED, to indicate
+ that field_width or precision has not been specified.
+ (print_formatted): Fail if field_width or precision is the
+ special value, UNSPECIFIED.
+ Reported by Oliver Kiddle <okiddle@yahoo.co.uk>
+
+ * src/sys2.h (INT_MIN): Define, if necessary.
+ * tests/misc/printf: Add a test for the above-fixed bug.
+
+2003-03-09 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (AD_stack_pop): Cast sizeof... to int before
+ changing its sign. This avoids a warning from gcc on 64-bit systems.
+ Reported by Bob Proulx.
+ (pop_dir): Reverse order of sign change and cast, to be consistent
+ with the above.
+
+2003-03-08 Jim Meyering <jim@meyering.net>
+
+ * tests/Makefile.am (evar-check): Check for POSIXLY_CORRECT not as a
+ shell variable, but only in the environment. With /bin/sh->bash, the
+ shell variable is set to `y', and that would cause a spurious warning.
+ Reported by Bob Proulx.
+
+ * tests/Makefile.am (check-root): Remove touch/fifo.
+ It doesn't appear to have to be run as root.
+
+ * tests/rm/fail-2eperm: Rather than simply using the first non-root
+ user name, make sure that the selected user name has a usable shell.
+ Reported by Paul Jarc.
+
+ Before, when using shred on a device, one had to specify --exact,
+ or be careful to choose a size that would not be rounded up and
+ exceed the maximum value; that could result in a failure of
+ the final write.
+ * src/shred.c (do_wipefd): --exact is now the default for non-regular
+ files. Suggestion from Ben Elliston.
+ (usage): Say it.
+
+ * tests/misc/tty-eof: Require at least version 1.11 of Expect.pm.
+ Old versions of Expect.pm (e.g., 1.07) lack the log_user function.
+ Patch by Bob Proulx.
+
+ * src/Makefile.am (check-misc): Check for use of `defined' in
+ #define directives.
+ Change to $(srcdir) before running grep.
+
+ * src/sleep.c: Remove now-unused #include and #define directives.
+
+ * src/du.c (process_file): If a file's size is not being counted
+ e.g., because it's a hard link to a file we've already counted,
+ then don't print a line for it.
+
+ * tests/du/hard-link: New test for the above-fixed bug.
+ * tests/du/Makefile.am (TESTS): Add hard-link.
+
+ `du -S' didn't work
+ * src/du.c: Revert most of the `reorganization' change of 2003-02-20,
+ and make the two-array approach work.
+
+ * tests/du/basic: Correct/add tests for the above fix.
+ Set LC_ALL, etc., now that we use sort.
+ Check the block/size of a small file, too.
+ Correct expected results for simple dir1/dir2/file case.
+ Add another test of du -S.
+
+2003-03-07 John David Anglin <dave.anglin@nrc-cnrc.gc.ca>
+
+ Avoid build failure with gcc on hppa1.1-hp-hpux10.20 (see GCC PR
+ middle-end/9986). As one of GCC's optimizations, it transforms a
+ fputs_unlocked call to a fputc_unlocked call when the string is
+ one character long. However, hpux doesn't have fputc_unlocked.
+
+ * expr.c (usage): Use putchar, not fputs, to output a single character.

+ * ptx.c (output_one_tex_line, output_one_dumb_line): Likewise.
+ * stat.c (print_it): Likewise.
+
+2003-03-07 Jim Meyering <jim@meyering.net>
+
+ * src/cp.c: Remove everything associated with mmap-stack.c.
+ This reverts the two changes of 2003-02-21.
+ * src/du.c: Remove everything associated with mmap-stack.c.
+ This reverts the change of 2003-02-19.
+
+2003-03-06 Jim Meyering <jim@meyering.net>
+
+ * tests/cp/same-file: Unset CDPATH. Otherwise, having the

+ Reported by Karl Berry.
+
+2003-03-05 Jim Meyering <jim@meyering.net>
+
+ * Version 4.5.9.
+
+ * src/printf.c (print_esc): Remove pointless comparison of unsigned
+ integer with zero, to avoid a warning from Intel's ecc.
+ Reported by Nelson Beebe.
+
+ * src/du.c (process_file): Sizes must all be of type uintmax_t.
+ Otherwise, for files or totals that are too big, numbers would
+ be truncated. Patch mostly by Michael Stone.
+ Reported by Ingo Saitz as Debian bug #183210.
+
+ * tests/du/8gb: New test for the above-fixed bug.
+ * tests/du/Makefile.am (TESTS): Add 8gb.
+
+ * src/du.c (MAX_N_DESCRIPTORS): Use 3 * UTILS_OPEN_MAX / 4
+ rather than UTILS_OPEN_MAX - 10.
+
+2003-03-04 Jim Meyering <jim@meyering.net>
+
+ * README: Refer new feature discussion to bug-coreutils@gnu.org,
+ rather than bug-gnu-utils, now that the former is better known.
+ Suggestion from Göran Uddeborg.
+
+ * src/stat.c (usage): Capitalize consistently.
+ Reported by Göran Uddeborg.
+
+ * Makefile.maint (rel-files): Include $(signatures), so that

+
+ * src/df.c (find_mount_point): Call error here, now that restore_cwd
+ no longer does it.
+ * src/remove.c (AD_pop_and_chdir): Likewise.

+ * tests/Makefile.am (check-root): Add fail-2eperm.
+
+2003-03-03 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (remove_cwd_entries): Include the full filename of
+ the offending file, not just the basename.
+
+ * tests/misc/tty-eof: Set $ME properly.
+
+ * Makefile.maint (THIS_VERSION_REGEXP, PREV_VERSION_REGEXP):
+ Remove now-unused variables.
+ (tag-prev-version, prev-cvs-tag): Likewise.
+
+ * src/remove.c (remove_cwd_entries) [!ROOT_CAN_UNLINK_DIRS]: Give an
+ accurate diagnostic when failing to remove a file owned by some other
+ user. Reported by Ivo Timmermans via Michael Stone.
+ This fixes Debian bug# 178471.
+
+ * tests/rm/Makefile.am (TESTS): Add fail-2eperm.
+ * tests/rm/fail-2eperm: New test, for the above-fixed bug.
+ Based on a report from Ivo Timmermans.
+
+2003-03-02 Jim Meyering <jim@meyering.net>
+
+ * src/copy.c (copy_internal) [un_backup]: When recovering from a

+2003-03-01 Jim Meyering <jim@meyering.net>
+
+ * src/df.c (print_header): Don't embed spaces in a separate `Type'

+ David Eisner reported that the behavior of --bytes had changed.
+ Paul Eggert proposed the use of a new option, --apparent-size.
+
+ * src/du.c (apparent_size): New global.
+ (print_only_size): Reflect the fact that we're printing byte counts,
+ not ST_NBLOCKSIZE-byte-block counts.
+ (print_size): Call print_only_size rather than duplicating its code.
+ (process_file): Accumulate byte counts, rather than block counts.
+
+ * src/du.c (process_file): Always reset size_to_propagate_to_parent
+ for --separate-dirs (-S).
+
+2003-02-20 Jim Meyering <jim@meyering.net>
+
+ * Use automake-1.7.3. Regenerate dependent files.
+
+ * src/stat.c (print_stat): New format: %B (to print ST_NBLOCKSIZE).
+ This makes %b (number of ST_NBLOCKSIZE-byte blocks) more useful.
+ (usage) [%B]: Describe it.
+ [%b]: Refer to %B.
+
+ * src/du.c (process_file): Reorganize the code to use only

+
+ * tests/du/basic: New test.
+ * tests/du/Makefile.am (TESTS): Add basic.
+
+ * tests/envvar-check: Add checks for the following:
+ BLOCK_SIZE, DU_BLOCK_SIZE, DF_BLOCK_SIZE, LS_BLOCK_SIZE.
+
+ * tests/Makefile.am: Rename phony target envvar-check to evar-check
+ so as not to conflict with the distributed file by the same name.
+
+ * src/du.c (process_file): Set info->skip before any possible return.
+
+ Report correct usage for directories, not 0.
+ * src/du.c (process_file): Return for `file_type == FTW_DPRE'
+ _before_ recording the dev/ino of a directory.
+ Reported by Bruno Haible.
+
+ Now, df always displays the device file name corresponding to the
+ listed mount point under `Filesystem'. Before, for an unmounted
+ block- or character-special file argument, it would display the
+ command-line argument instead.
+ * src/df.c (show_disk): Return a value indicating whether
+ there was a match. Don't try to find a mount point here.
+ (show_entry): If show_disk doesn't find a match, call show_point.
+
+2003-02-19 Jim Meyering <jim@meyering.net>
+
+ * src/du.c: Include "mmap-stack.h".
+ (du_files): Add prototype with ATTRIBUTE_NORETURN.
+ Exit from this function, not from...
+ (main): ...here.
+ Instead, if possible, invoke du_files through a macro that
+ runs it with a large, mmap'd stack.
+
+ * src/join.c (usage): Change wording in --help output:
+ use FILENUM instead of `SIDE' and say what FILENUM means.
+ Reported by Bernhard Gabler.
+
+ * src/df.c (print_header): Rather than using a hard-coded literal
+ string of spaces matching the length of the English `...Type' header,
+ output the right number of spaces to match the selected translation.
+ Reported by Yann Dirson and Jean Charles Delepine as Debian bug 131113.
+
+ * src/split.c (bytes_split): Remove unnecessary `else' after break.
+ (lines_split): Likewise. and correct misleading indentation.
+
+ * src/split.c: Include "full-read.h".
+ (bytes_split, lines_split, line_bytes_split): Use full_read,
+ not safe_read. The way split was using the latter, a short read
+ could cause split to terminate before EOF.
+
+ * tests/misc/tty-eof: Test all programs that can read stdin,
+ requiring no arguments and that write to standard output.
+
+ * tests/misc/tty-eof: New file. Renamed from ...
+ * tests/misc/cat-tty-eof: Remove file. Rename to tty-eof.
+ * tests/misc/Makefile.am (TESTS): Reflect renaming.
+
+2003-02-18 Jim Meyering <jim@meyering.net>
+
+ cksum would perform an extra read after encountering EOF

+
+2003-02-10 Jim Meyering <jim@meyering.net>
+
+ * src/test.c: Don't include group-member.h.
+ Include euidaccess.h.
+ (eaccess): Rewrite function to set the real uid and gid temporarily
+ to the effective uid and gid, then invoke 'access', and then set the
+ real uid and gid back. On systems that lack setreuid or setregid,
+ fall back on the kludges in euidaccess. Before, it would not work
+ for e.g., files with ACLs, files that were marked immutable,
+ or on file systems mounted read-only. Nelson Beebe raised the issue.
+ Paul Eggert suggested the new implementation.
+
+2003-02-09 Jim Meyering <jim@meyering.net>
+
+ * src/test.c (test_stat): Remove function. It's job is done (only

+
+ `df /dev/block-or-char-device-file--not-mounted' now reports

+ Before, it would leave the `Mounted on' field blank.
+ * src/df.c (show_disk): Move function to precede find_mount_point.
+ (show_disk): Add parameter: STATP.
+ If we don't find a matching device name, then resort to calling

+2003-01-31 Richard Dawe <rich@phekda.freeserve.co.uk>
+
+ * tests/basename/Makefile.am: Use @PATH_SEPARATOR@ instead of

+ (print_human_type): Remove function.
+ (human_access): Rename from print_human_access. Return a string.
+ (human_time): Rename from print_human_time. Return a string.
+ (print_stat): Arrange so that field width and an alignment specifier
+ are honored for the %A, %F, %x, %y, and %z formats.
+ [%F]: Use file_type; this gives slightly different file type strings,
+ e.g., `directory' instead of `Directory' and `regular file' or
+ `regular empty file' instead of `Regular file'.
+ Prompted by a report from Richard Dawe that the uses of

+
+2003-01-31 Richard Dawe <rich@phekda.freeserve.co.uk>
+
+ * src/stat.c (print_stat): Use S_ISLNK rather than an explicit

+
+2003-01-31 Jim Meyering <jim@meyering.net>
+
+ * src/du.c (main): Upon processing an invalid option or an invalid
+ --exclude-from or --max-depth option argument, don't exit right away,
+ in case there are others. Rather record the failure and exit after
+ processing other options.
+
+ * GNUmakefile (TAR_OPTIONS): Set and export, in order to make
+ tar archive easier to reproduce.
+
+ Rewrite to perform directory traversal using nftw.
+
+ * src/du.c: Include "dirname.h", "ftw.h", and "quotearg.h".

+
+2003-01-27 Andreas Schwab <schwab@suse.de>

+2003-01-27 Jim Meyering <jim@meyering.net>
+
+ * src/ls.c (decode_switches): If `dired' is set without

+ (DIRED_INDENT): ... remove the `format == long_format' conjunct.

+2003-01-21 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (remove_entry) [ROOT_CAN_UNLINK_DIRS

+ Based on a patch by Michael van Elst.

+
+2003-01-19 Jim Meyering <jim@meyering.net>

+ (enum) [DEREFERENCE_COMMAND_LINE_SYMLINK_TO_DIR_OPTION]: New member.
+ (long_options): Add option --dereference-command-line-symlink-to-dir.
+ (main): Make DEREF_COMMAND_LINE_SYMLINK_TO_DIR be the default,

+ -d, -F, -l options is specified.
+ (decode_switches): Handle --dereference-command-line-symlink-to-dir.
+ (gobble_file): Honor DEREF_COMMAND_LINE_SYMLINK_TO_DIR.

+ command line arguments, including broken symlinks.
+
+2003-01-15 Paul Eggert <eggert@twinsun.com>
+
+ Change ls -H back to the way it was yesterday, since this is

+ from DEREF_COMMAND_LINE_SYMLINK_TO_DIR, updating all uses.
+ (long_options): Change the long option name back.

+ (gobble_file): When -H is specified, dereference a top-level
+ arg even if it points to a non-directory.
+
+2003-01-15 Jim Meyering <jim@meyering.net>
+
+ * src/ls.c (gobble_file): Fall back on using lstat when required:
+ when --dereference (-L) is not specified, and
+ - when operating on a dangling symlink
+ - when operating on command-line-symlink-to-directories
+ This fixes numerous problems. Here are examples:
+ - `ls dangling-symlink' would fail with `no such file...'
+ Now it prints `dangling-symlink'.
+ - `ls -i symlink' would mistakenly print the inode of the referent.
+ Now it prints the inode of the symlink. Likewise for --size (-s).
+ Based on a patch from Michael Stone.
+ Reported by Deepak Goel as Debian bug #173793.
+
+ Rename ls's --dereference-command-line (-H)
+ option to --dereference-command-line-symlink-to-dir.
+ * src/ls.c [enum Dereference_symlink]
+ (DEREF_COMMAND_LINE_SYMLINK_TO_DIR): Rename from
+ DEREF_COMMAND_LINE_ARGUMENTS. Update all uses.
+ (long_options): Rename the long option.
+ (usage): Say that --dereference-... changes how ls treats
+ only symlinks to directories specified on the command line.

+
+ * ls.c (gobble_file): Remove the block of code that caused

+ like `ls -F symlink-to-dir') but with the addition of highlighting.
+ Similarly, `ls --color -dF symlink-to-dir' would print
+ `symlink-to-dir/'; now it prints `symlink-to-dir@'.
+ Reported by Jeff Sheinberg as Debian bug #168203.

+
+ * Makefile.maint (mail_gpg_sign_cookie): Make optional.
+ (announcement): Use the new variable.
+
+ * Makefile.maint: Sync with Bison, i.e.:
+ (po-check): Scan .l and .y files instead of the
+ .c and the .h files that they generate. This fixes the bug
+ reported by Tim Van Holder in:
+ <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
+ Look for N_ as well as for _. Try to avoid matching #define for

+2002-10-07 Paul Eggert <eggert@twinsun.com>
+
+ Add support for locale-specific size indications (e.g.,
+ thousands-separators) and for explicit size suffixes on output.
+
+ * doc/coreutils.texi (Block size): Say that:
+ This affects display format as well as block size.
+ Fractional block counts are rounded up.
+ ls file size blocksize defaults to 1.
+ A block size spec preceded by ' generates thousands separators.
+ A suffix without a preceding integer generates suffixes.
+ (tail invocation): 32k -> 32 KiB.
+ (What information is listed): ls -h is now equivalent to
+ ls --block-size=human, and ls -H is now equivalent to

+ human_base_1024, human_SI, human_B): New enum values.
+ (human_readable): Rename from human_readable_inexact; put the
+ options before the sizes. All uses changed. The old human_readable
+ function has been removed; use inttostr.h instead.
+ (human_options): Renamed from human_block_size, with new signature
+ that allows block sizes up to UINTMAX_MAX. All callers changed.
+
+ * m4/prereq.m4 (jm_PREREQ_HUMAN): Check for locale.h, localeconv,
+ AC_HEADER_STDBOOL. No need to check for limits.h since it's in
+ freestanding C89. No need to check for stdlib.h or string.h since
+ autoconf does this now.
+
+ * src/cksum.c (cksum): Use primitives from inttostr.h, not

+ * src/du.c: Likewise.
+ * src/ls.c: Likewise.
+
+ * src/df.c (print_header): In the header line, prefer SI to human
+ representation if it's shorter; if neither is shorter, try to
+ intuit what the user would prefer.
+
+ * src/expr.c (inttostr): Remove; use new imaxtostr library
+ function instead.
+
+ * src/ls.c (file_output_block_size): New var, to distinguish
+ file sizes from other sizes.
+ (decode_switches): Set it.
+
+ * src/shred.c (OUTPUT_BLOCK_SIZE): remove.
+ (dopass): When printing progress, use floor for what has been done
+ so far (since we should be conservative there), and ceiling for
+ what needs to be done (since that's what other programs use).

+ Reported by Petter Reinholdtsen.
+
+2002-10-14 Jim Meyering <jim@meyering.net>
+
+ Specifying a printf conversion specifer as nl's separator string
+ could cause nl to segfault.
+ * src/nl.c (build_print_fmt): Don't include separator string

+
+2002-10-12 Jim Meyering <jim@meyering.net>

+ (read_input): Adapt to new safe_read ABI.
+
+ * src/cut.c (cut_fields): Add a temporary size_t variable, n_bytes,
+ to avoid warnings.
+
+ * src/pinky.c (print_long_entry): fread returns size_t.
+ Declare local `bytes' accordingly, to avoid warning.
+
+ tail -c +N would perform an extra read after encountering EOF
+ [this change is analogous (bytes vs. lines) to the one of 2002-01-27]
+ * src/tail.c (start_bytes): Detect EOF, inform caller.

+2002-10-02 Jim Meyering <jim@meyering.net>
+
+ * Makefile.am (SUBDIRS): Remove `old'.
+ (EXTRA_DIST): List the files in old/.
+ * configure.ac (AC_CONFIG_FILES): Remove old/* names.
+ Suggestion from Akim Demaille.
+
+2002-10-01 Jim Meyering <jim@meyering.net>
+
+ * src/sys2.h (SSIZE_MAX): Define.
+
+2002-09-30 Jim Meyering <jim@meyering.net>
+
+ * src/csplit.c: Don't include stdlib.h here. It's already included
+ via system.h.
+
+2002-09-29 Jim Meyering <jim@meyering.net>
+
+ * src/tr.c (find_bracketed_repeat): Rearrange pointer/integer
+ expression to avoid bogus warning from gcc.
+
+ * src/cat.c (simple_cat): Use a temporary to avoid bogus warnings.
+ (cat): Declare insize and outsize to be of type size_t, not int.
+ Rearrange pointer/integer expressions to avoid bogus warnings.
+ (main): Declare insize and outsize to be of type size_t, not int.
+
+ * src/tail.c (parse_options): Give a sensible diagnostic for
+ an invalid byte or line count. Reported by Mikko Tuumanen.
+
+ * src/touch.c (main): Split a long line.
+
+ * tests/du/Makefile.am (TESTS): Add slink.
+ * tests/du/slink: New test for system.h change of 2002-08-31.
+
+ In move mode, always first try to rename. Before, upon failure to
+ rename a directory, this code would never attempt to rename any
+ other file in that directory, but would thenceforth always copy.
+ On some systems (e.g., NetApp's OnTap-6.4), renaming a directory
+ may fail with EXDEV, yet renaming files within that directory to
+ a newly-created destination directory succeeds.
+ * src/copy.c (copy_internal): Remove local, move_mode;
+ use x->move_mode instead. Based on a patch from Tom Haynes.
+
+2002-09-28 Jim Meyering <jim@meyering.net>
+
+ * src/split.c (FAIL_ONLY_ONE_WAY): New macro.
+ Factor out some duplication.
+ (main): Use it.
+ [case 'a']: Use strtoul rather than strtol to avoid compiler warnings.
+
+ * src/sort.c (begfield, limfield): Rearrange comparisons to avoid
+ compiler warnings.
+ (fillbuf, keycompare): Cast literal `-1' to size_t in comparisons,
+ to avoid compiler warnings.
+
+ * src/shred.c (dopass): Use a uintmax_t temporary to avoid bogus
+ compiler warnings.
+
+ Fix things so `mkdir -p' can create very deep directories, e.g.,
+ mkdir -p $(perl -e 'print "a/" x 40000') now works.
+ * src/mkdir.c (main): For --parents (-p), call make_path with the
+ entire directory name, so we don't ever require that file operations
+ like stat or chmod be performed on the entire command line argument.
+ * makepath.c (make_path): Restore umask *before* creating the final
+ component.
+
+2002-09-27 Andreas Schwab <schwab@suse.de>
+

+
+2002-09-25 Jim Meyering <jim@meyering.net>

+ since it's already included from sys2.h via system.h.
+
+ * Use automake-1.6f. Regenerate dependent files.
+
+ * src/Makefile.am (PERL): Remove duplicate definition.
+
+ fmt's -s, -t, -c options didn't work properly for long lines.
+ Since get_line may end up calling put_paragraph (for long lines),
+ be sure to set global, `other_indent', before it is used there.
+
+ * src/fmt.c (set_other_indent): New function, factored out of...
+ (get_paragraph): ... here. Call it.
+ (get_line): Call set_other_indent before calling flush_paragraph,
+ which calls fmt_paragraph, which in turn calls put_paragraph,
+ which uses other_indent.
+
+ * tests/fmt/Makefile.am (TESTS): Add long-line.
+ * tests/fmt/long-line: New file/test, for the above fix.
+
+2002-09-21 Jim Meyering <jim@meyering.net>

+
+2002-09-06 Andreas Schwab <schwab@suse.de>

+
+2002-09-18 Jim Meyering <jim@meyering.net>
+
+ `od -t x8' used the wrong (`l'-prefixed) printf format.
+ Likewise for the o8 and u8 formats.
+ * src/od.c (ISPEC_TO_FORMAT): Define macro.
+ (decode_one_format): Use PRIdMAX, PRIoMAX, etc. for LONG_LONG.
+ Reported by Arun Sharma.
+
+2002-09-17 Jim Meyering <jim@meyering.net>
+
+ * src/sys2.h (PRIdMAX, PRIoMAX, PRIuMAX, PRIxMAX): Define if necessary.
+ From gettext's intl/loadmsgcat.c.
+
+ * tests/od/x8: New file/test, for the above fix.
+ * tests/od/Makefile.am (TESTS): Add x8.
+
+2002-09-15 Jim Meyering <jim@meyering.net>

+ to avoid warnings about `comparison between signed and unsigned'.
+ * src/ptx.c (generate_all_output): Likewise.
+
+ * src/dd.c (main, skip): Add casts to avoid warnings about
+ `comparison between signed and unsigned'.
+
+ * src/id.c (print_full_info, print_group_list): Add casts to avoid
+ warnings about `signed and unsigned type in conditional expression'.
+
+ * src/md5sum.c: Change type of global, digest_hex_bytes, to size_t
+ to avoid warnings about `comparison between signed and unsigned'.
+ (split_3): Change parameter names to be readable and add comment.
+ Clean up the test for whether a line may be ignored.
+
+2002-09-13 Jim Meyering <jim@meyering.net>
+
+ * src/printf.c (main): Handle leading command line argument of `--'.
+ Reported by Raul: DervishD <raul@pleyades.net>
+ * tests/misc/printf: New file: test for the above.
+ * tests/misc/Makefile.am (TESTS): Add printf.
+
+ * src/date.c (usage): Explain that %S's range of [0..60] is required --
+ rather than 0..59 -- to accommodate the occasional positive leap second.
+ Reported by Richard Neill.
+
+2002-09-12 Jim Meyering <jim@meyering.net>
+
+ * src/Makefile.am (nanosec_libs): Define.
+ (sleep_LDADD, tail_LDADD): Use it here.
+
+ Factor nanosleep-related code into ../lib/xnanosleep.c.
+ * src/sleep.c: Include xnanosleep.h.
+ Factor out fenv.h-related code.
+ (timespec_subtract): Remove function.
+ (main): Remove code that deals with computing start and stop times
+ as well as the loop around nanosleep. Now that's in xnanosleep.c.
+
+ Allow S (in --sleep-interval=S) to be a floating point value.
+ * src/tail.c: Include xnanosleep.h and xstrtod.h.
+ Move declaration of global variable, sleep_interval, to ...
+ (main): ...here.
+ (usage): Update description of --sleep-interval option.
+ (tail_forever): New parameter, sleep_interval. Update caller.
+ Use xnanosleep, rather than sleep.
+ (parse_options): New parameter, sleep_interval. Update caller.
+ Use xstrtod, now that we accept floating point values.
+ Prompted by a patch from Augey Mikus.
+
+2002-09-06 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (prompt): Change comment to give a better note to
+ translators. From Michael Piefel.
+
+2002-09-02 Jim Meyering <jim@meyering.net>
+
+ * README: A good problem report/patch includes diffs against

+2002-08-31 Jim Meyering <jim@meyering.net>
+
+ Symlinks were always reported as using 0 blocks.
+ * src/system.h (ST_NBLOCKS): Don't depend on file type.
+ This reverts the change of 2000-01-30.
+ Based on a report and patch from Neil Brown via Michael Stone.
+ This fixes Debian Bug#156358.
+
+ * Most files: Change `exit (0)' to `exit (EXIT_SUCCESS)',
+ `exit (1)' to `exit (EXIT_FAILURE)', and
+ `usage (1)' to `usage (EXIT_FAILURE)'.
+
+ * chgrp.c, chmod.c, chown.c, chroot.c, cp.c, date.c, dd.c, du.c,

+ error never exits successfully.
+
+2002-08-29 Jim Meyering <jim@meyering.net>
+
+ * src/remove.c (remove_cwd_entries): Use closedir (not CLOSEDIR)
+ when ignoring any return value.

+
+2002-08-10 Paul Eggert <eggert@twinsun.com>

+ shouldn't be needed.
+
+2002-08-09 Jim Meyering <jim@meyering.net>
+
+ * src/pr.c (main): Don't ignore -COLUMN if it's the last option.
+ (usage): Clarify help text for the -COLUMN option.
+ Patch by Padraig Brady.
+ * tests/pr/Test.pm [col-last]: New test for the above.

+ programs in ../src.
+
+2002-08-08 Jim Meyering <jim@meyering.net>

+
+2002-08-05 Paul Eggert <eggert@twinsun.com>
+
+ Fix some minor time-related bugs with POSIX time arguments.
+ Some valid time stamps were being rejected (notably -1, and
