2006-12-20"cut -f 2- A B" no longer triggers a double-free bugJim Meyering
* src/cut.c (cut_fields): Set file-scoped global to NULL after freeing it. This avoids a double-free (and core dump on some systems) for this usage: "echo 1>a; echo 2>b; cut -f2- a b". Reported by James Hunt in <http://bugzilla.redhat.com/220312>. * NEWS: List this bug fix. * THANKS: Mention him. * tests/misc/cut: New file. * tests/misc/Makefile.am (TESTS): Add cut.

three).
2005-07-05Adjust to the change to DECIMAL_DIGIT_ACCUMULATE: its last arg is nowPaul Eggert
a type, not a value.

2005-03-06Remove `register' keyword.Jim Meyering
2004-12-04(complement, COMPLEMENT_OPTION): New.Jim Meyering
(longopts): Add --complement. (usage): Say not that -b, -c, and -f `print' fields, but rather that they `select' fields for printing. Describe the new --complement option. (mark_range_start): Extracted from set_fields. (print_kth): Support --complement. (compare_ranges): New function. (set_fields): Rewrite the part that populates range_start_ht, merging it with the part that populates printable_field. (main): Handle --complement. From Paolo Bonzini.

by Debian 5.2.1-2.

2004-06-02Fix a bug in how the --output-delimiter=D option works withJim Meyering
abutting byte or character ranges. Reported by David Krider in http://lists.gnu.org/archive/html/bug-coreutils/2004-05/msg00132.html (print_kth): Remove special case for open-ended range. (set_fields): Record the range start index for an interval even when it abuts another interval on its low side. Also record the range start index of the longest right-open-interval.

2003-11-06Fix 'cut' problems with size_t overflow and unsigned int.Jim Meyering
More generally, resize integer variables to fit use more precisely. (ADD_RANGE_PAIR): Remove unnecessary parens. (struct range_pair): Make members to be of type size_t, not unsigned. (max_range_endpoint, eol_range_start): Now size_t, not unsigned. (suppress_non_delimited, output_delimiter_specified, have_read_stdin, print_kth, set_fields): Now bool, nt int. (delim): Now unsigned char, not int. (mark_printable_field, is_printable_field, is_range_start_index, set_fields, set_fields, cut_bytes, cut_fields): Use size_t, not unsigned, for field and byte counts. (hash_int): Use uintptr_t, not unsigned, for pointers converted to integers. This squeezes more info out of them. (set_fields, cut_bytes, cut_fields, main): Use bool, not int, for booleans. (set_fields): Allocate zeroed byte array with xzalloc, not xcalloc.
2003-11-04(ADD_RANGE_PAIR): Use x2nrealloc rather than xrealloc,Jim Meyering
to avoid potential overflow in pointer arithmetic. (set_fields): Use not `1', but rather `sizeof *printable_field' as second argument to xcalloc.
2003-10-25(hash_int): Adjust to reflectJim Meyering
type changes (unsigned int -> size_t) in hash.c.
2003-10-18Most .c files (AUTHORS): Revert the WRITTEN_BY/AUTHORS changeJim Meyering
of 2003-09-19. Now, AUTHORS is a comma-separated list of strings. Update the call to parse_long_options so that `AUTHORS, NULL' are the last parameters. * src/true.c (main): Append NULL to version_etc argument list. * src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
2003-09-18(WRITTEN_BY): Rename from AUTHORS.Jim Meyering

2003-09-18Update AUTHORS definition to be a comma-separated list of strings and/or updateJim Meyering
the call to parse_long_options so that `AUTHORS, NULL' are the last parameters.
2003-08-07Include getndelim2.h rather than getdelim2.h.Jim Meyering
(cut_fields): Invoke getndelim2 rather than getdelim2.
2003-08-02(cut_fields): Don't read again after encountering EOF.Jim Meyering
E.g., `cut -f2' would do so.

2003-07-26Use only one bit per field/offset in array, not one `int'.Jim Meyering
(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'.
2003-07-26(set_fields): Detect overflow properly.Jim Meyering
2003-07-23Don't include headers already included by system.h:Jim Meyering

2003-07-22(set_fields): Mark all selected indices before trying toJim Meyering
determine range endpoints.
2003-07-22Begin to address this comment: What if someone wants toJim Meyering
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. (RANGE_START_SENTINEL): Remove. Store range-start indices in a hash table, rather than overloading the `printable_field' array. (range_start_ht): New global. (hash_int, hash_compare_ints, is_range_start_index): New functions. (print_kth): Use is_range_start_index; don't test printable_field. (set_fields): Detect overflow. (set_fields): Insert each range-start index into range_start_ht. (main): Call set_fields only once, and only after output_delimiter_specified and (if required) range_start_ht have been defined.
2003-06-18Include "getdelim2.h", not "getstr.h".Jim Meyering
Reflect renaming: getstr -> getdelim2.
2003-06-17(main): Call initialize_main.Jim Meyering
2003-04-11Remove anachronistic casts of xmalloc,Jim Meyering
xrealloc, and xcalloc return values and of xrealloc's first argument.
2003-01-09When selecting ranges of byte offsets (as opposed to ranges of fields)Jim Meyering
and when --output-delimiter=STRING is specified, output STRING between ranges of selected bytes. (RANGE_START_SENTINEL): Define. (output_delimiter_specified): New global. (print_kth): Add parameter. Adjust all callers. (set_fields): Mark each range-start index with RANGE_START_SENTINEL. (cut_bytes): When requested, output STRING between ranges of selected bytes. (main): Make a diagnostic a little clearer. Based on a patch from Jan Nieuwenhuizen.
2003-01-09(set_fields): Make code agree with comment:Jim Meyering
Don't merge abutting ranges like 4- and 2-3. This makes no difference currently, but is required to support an upcoming change.
2003-01-07(set_fields): Fix typo in comment.Jim Meyering
2002-10-12(cut_fields): Add a temporary size_t variable, n_bytes, to avoid warnings.Jim Meyering
2002-07-02(usage): Use the PACKAGE_BUGREPORT e-mail address, rather than hard-coding it.Jim Meyering
2001-12-01Reflect renaming to, and new usage of these macros:Jim Meyering
HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION.
2001-12-01(usage): Use new macros, EMIT_HELP_DESCRIPTION and EMIT_VERSION_DESCRIPTIONJim Meyering
instead of hard-coding --help and --version descriptions.
