2005-05-12Assume `free (NULL)' works.Jim Meyering
2005-05-02(usage): ls --indicator-style=directory renamed to lsPaul Eggert
--indicator-style=slash, to avoid confusion with ls --directory. (slash): Renamed from directory_only. All uses changed.
2005-04-29(enum indicator_style): New constant directory_only,Paul Eggert
for -p. (indicator_style_args, indicator_style_types): Set it appropriately. (decode_switches, gobble_file, print_type_indicator): (length_of_file_name_and_frills): Implement the change described in NEWS. (decode_switches): Quote ">", too. (usage): Update to match the new behavior. Describe ">".
2005-04-12(usage): uid -> user IDPaul Eggert
2005-04-09(SA_NOCLDSTOP): Define to 0 if not defined.Paul Eggert
All uses changed. (siginterrupt) [! HAVE_SIGINTERRUPT]: New macro. (main) [! SA_NOCLDSTOP]: Use it.
2005-03-28(time_style_args, indicator_style_args, long_options)Jim Meyering
(format_args, sort_args, time_args, decode_switches) (gobble_file): Use NULL, not `0'.
2005-03-26(usage): Document usage of LS_COLORS.Jim Meyering
2005-03-22(get_funky_string): Use '\a', rather than 7, for portability to EBCDIC hosts.Jim Meyering
2005-03-11(TIME_STAMP_LEN_MAXIMUM): New constant.Paul Eggert
(long_time_expected_width, print_long_format): Use it, to avoid some possible denial-of-service attacks.
2005-03-10(long_time_expected_width): Use x2nrealloc, not alloca,Jim Meyering
so format string abuse cannot provoke stack overflow. (print_long_format): Likewise.
2005-03-06Remove `register' keyword.Jim Meyering
2005-02-21(time): Remove obsolete decl.Paul Eggert
(get_current_time): gettimeofday always returns 0, so don't check its result.
2004-12-17(print_dir): Use "%s: not listing already-listedPaul Eggert
directory", not "not listing already-listed directory: %s", to format already-listed directories, to be consistent with other diagnostics involving file names and colons.
2004-12-14(gobble_file): Change arg name to be command_line_argPaul Eggert
rather than explicit_arg, for consistency with copy.c. (extract_dirs_from_files): Remove ignore_dot_and_dot_dot arg, since it is deducible from dirname arg. All callers changed. (extract_dirs_from_files, print_dir, queue_directory): Add command_line_arg arg. All callers changed. (struct pending): Add command_line_arg member. (main): Use NULL rather than 0 when appropriate. (set_exit_status, file_failure): New functions. (queue_directory): Store command_line_arg into new structure. (print_dir, gobble_file, get_link_name): Use file_failure to report problems in accessing files, so that the exit status is set consistently. (print_dir): Simplify readdir failure code yet again. If closedir fails, report "closing directory" rather than "reading directory" failure. (xstrcoll): Use set_exit_status to set status on failure.
2004-12-09(LS_MINOR_PROBLEM, LS_FAILURE): New constants.Paul Eggert
All uses of EXIT_FAILURE replaced with LS_FAILURE, unless specified below. (main): Initialize exit failure to LS_FAILURE. (print_dir, gobble_file, get_link_name, xstrcoll): Set exit status to LS_MINOR_PROBLEM if the failure is minor. (print_dir): Do not give up on entire directory merely because readdir returns EOVERFLOW. (usage): Explain exit status.
2004-12-02With using --color and with LS_COLORS saying not to colorJim Meyering
executables, don't stat every file. (is_colored): New function. (gobble_file): Use it. (main): Use it here, in place of too-strict tests against NULL: if either ORPHAN or MISSING was set to 0 from LS_COLORS, the old test would fail.
2004-12-02(sort_files): Minor cleanup. Remove an unnecessaryPaul Eggert
'volatile' on a local variable. Rewrite to avoid unnecessary double-assignment to 'func' in the usual case where strcoll does not fail.
2004-11-19(usage): Clarified description of --no-group (-G),Jim Meyering
--human-readable (-h), --inode (-i), --size (-s), --time, and --time-style.
2004-11-19(usage): Clarify description of --author.Jim Meyering
Tweak indentation so that help2man creates better nroff.
2004-10-05(ignore_mode): Renamed from ignore, to avoid shadowingPaul Eggert
problems. All uses changed.
2004-10-05remove trailing blanks.Jim Meyering
2004-09-26Add "ls --hide".Paul Eggert
(file_ignored): Renamed from file_interesting, with inverted return value. Accept the file name, not a struct dirent *. All uses changed. Avoid the expense of calling fnmatch if the file is ignorable due to leading '.'. (all_files, really_all_files): Removed; replaced by: (ignore): New variable. All uses changed. (IGNORE_DEFAULT, IGNORE_DOT_AND_DOTDOT, IGNORE_MINIMAL, HIDE_OPTION): New constants. (hide_patterns): New variable. (long_options, decode_switches, file_ignored, usage): Add support for --hide. (patterns_match): New function. (usage): Replace "hide" with "ignore" in explanation, to avoid confusion.
2004-09-26Remove unused variable.Paul Eggert
2004-09-26(gobble_file, print_long_format): Don't assume thatPaul Eggert
human-readable output has a byte count equal to its column width; this isn't always true in locales where the radix character is not '.' or ','. (format_user_or_group): Revamp code to match the above fix; this avoids the (very faint) possibility of integer overflow.
2004-09-22(decode_switches): Don't compare a short valuePaul Eggert
to SIZE_MAX: GCC sometimes complains.
2004-09-21Remove unused "case 0".Paul Eggert

(dir_defaulted): Remove; no longer needed. (main): Use int to count files, since it suffices for argv. Rewrite to avoid need for dir_defaulted. (main, print_dir, gobble_file, get_link_name, xstrcoll): Set exit status to EXIT_SUCCES/EXIT_FAILURE rather than 0/1. (decode_switches): Put back check for ws.ws_col <= SIZE_MAX. Remove unnecessary cast to int. Use int instead of unsigned int to count from 0 to 1. (get_funky_string, print_type_indicator): Use char for bytes, not int. (make_link_path): Use NULL for null pointers. (quote_name): Use to_uchar instead of cast.
2004-06-22Fix bug: GNU 'ls' didn't count columns correctly if user or groupJim Meyering
names contained multibyte characters where the column count differed from the byte count. This patch also corrects some comments. (format_user_or_group): New function, which counts columns correctly. (format_user, format_group): Use it. (format_user_or_group_width): New function, which counts columns correctly. (format_user_width, format_group_width): Use it.
2004-06-15(decode_switches): Pay attention to TABSIZE even if POSIXLY_CORRECTJim Meyering
is set. POSIX reserves upper-case environment variables to the implementation, so it's OK for ls to depend on TABSIZE.
2004-06-01(get_link_name): Update use of xreadlink.Jim Meyering
2004-04-24More signal-handling cleanup for ls.c. Do not allow signals toJim Meyering
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. (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: New macros. Do not include "full-write.h"; no longer needed. (tcgetpgrp) [! HAVE_TCGETPGRP]: New macro. (put_indicator_direct): Remove. All callers changed to use 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.
2004-04-23Avoid segfault on systems for which SIZE_MAX != (size_t) -1.Jim Meyering
(quote_name): Use SIZE_MAX, not -1, in calls of quotearg_buffer. Patch by Mikulas Patocka.
2004-04-21 - ls could incorrectly restore color if multiple signalsJim Meyering
arrived nearly simultaneously. (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. (sighandler) [defined SA_NOCLDSTOP]: Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent. (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.
2004-02-02(TIMESPEC_NS): Remove definition.Jim Meyering
2004-01-21(usage): Use EXIT_SUCCESS, not 0, for clarity.Jim Meyering
(main): Don't assume EXIT_FAILURE == 1, as POSIX doesn't require it.
2003-12-24(length_of_file_names_and_frills):Jim Meyering
Remove forward decl; not needed. (print_file_name_and_frills, length_of_file_name_and_frills): With -m, don't output spaces before inum or size. (print_with_commas): Don't output space just before newline.
2003-12-18(format_user): Increment dired_pos via two statements,Jim Meyering
`dired_pos += width; dired_pos++;' rather than one, `dired_pos += width + 1;' since the latter could conceivably overflow. (format_group): Likewise.
2003-12-08(INODE_DIGITS, LOGIN_NAME_MAX, ID_LENGTH_MAX): Remove.Jim Meyering
(format_user_width, format_group_width, unsigned_file_size, format_group): New functions. (block_size_width): Renamed from block_size_size. (inode_number_width, nlink_width, owner_width, group_width, author_width, major_device_number_width, minor_device_number_width, file_size_width): New vars. (clear_files): Initialize them. (gobble_file): Set them. Don't ceiling block_size_width to 7. (print_long_file): Use them. (gobble_file): Use a new local variable 'f' to make the code smaller and more consistent with other functions. (format_user): Output to stdout, not to a buffer, so that we don't have to worry about buffer overrun. Update dired_pos. (print_long_file): Don't put owner, group, author into buffer; just print them directly. Don't assume link counts and major and minor numbers fit into unsigned long int. From Paul Eggert.
2003-11-12(extract_dirs_from_files): Avoid useless copy operations.Jim Meyering
This avoids a warning valgrind about memcpy with overlapping source and destination.
2003-10-25(dev_ino_hash): 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.
2003-10-14(decode_switches) [TIOCGWINSZ]: Comment out theJim Meyering
warning-inducing test, ws.ws_col <= SIZE_MAX, since it was always true on Linux.
2003-10-14Fix to avoid a denial-of-service attack if the display width isJim Meyering
enormous. Also, clean up the code a bit by removing duplicate code. (init_column_info): Remove forward decl; no longer needed. (calculate_columns): New function, that contains code that used to be common to print_many_per_line and print_horizontal. (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 now does that. (init_column_info): Don't allocate a lot more space than is needed to represent the current set of files. Allocate all the new size_t cells in one call to xnmalloc, rather than a row at a time.
2003-10-13(init_column_info): Add another FIXME comment.Jim Meyering
2003-10-13(struct bin_str.len, length_of_file_name_and_frills, indent,Jim Meyering
nfiles, files_index, tabsize, line_length, struct column_info.line_len, struct column_info.col_arr[0], max_idx): Now size_t, not int. (get_funky_string): Return bool indicating success, instead of a negative count to indicate failure. Store number of columns through new parameter OUTPUT_COUNT; that way, they can never go negative. Change equals_end from int to bool. All uses changed. (struct column_info.valid_len): Now bool, not int. All uses changed. (dired_dump_obstack, get_funky_string, clear_files, extract_dirs_from_files, print_current_files, print_many_per_line, print_horizontal, init_column_info, put_indicator, length_of_file_name_and_frills, print_with_commas): Use size_t, not int, for local variables that count sizes. (decode_switches): Decode sizes using xstrtoul, not xstrtol. Check for TIOCGWINSZ returing negative values (or values greater than SIZE_MAX!). (visit_dir, main, parse_ls_color, queue_directory, add_ignore_pattern, init_column_info): Use xmalloc and xnmalloc, not XMALLOC. (gobble_file): Use xnrealloc, not XREALLOC. (print_color_indicator): Remove now-unnecessary cast to size_t.
2003-10-13(print_many_per_line): Add FIXME comment.Jim Meyering
2003-09-28Remove unnecessary casts of alloca, since now it's guaranteed to be (void *).Jim Meyering
