New -y or --bzip2 option.
(add_filtered_exclude): New function.
(decode_options): Put excluded patterns with / into excluded_with_slash,
and without / into excluded_without_slash.
Compare newer_mtime_option to its new initial value TYPE_MINIMUM (time_t)
when deciding whether more than one threshold date was specified.
(base_8_digits): New macro.
(MAX_VAL_WITH_DIGITS): New macro.
(to_base): Renamed from to_oct. Support base 64 too.
New parameters specifying bits per digit and digits.
Remove `type' parameter. The result is now undefined if it doesn't fit;
it's the caller's responsibility to check this.
(to_chars): Other half of old to_oct, for 64-bit support.
Mostly a new function.
(GID_NOBODY, UID_NOBODY): Don't define if the headers don't.
(gid_substitute, uid_substitute): Look up names dynamically if
GID_NOBODY and UID_NOBODY aren't defined; use -2 if all else fails.
(mode_to_chars): Renamed from mode_to_oct.
Support negative values in all the _to_chars functions.
(start_header): Use FILESYSTEM_PREFIX_LEN instead of MSDOS ifdef.
Abort if archive format is DEFAULT_FORMAT when it shouldn't be.
(dump_file): Inspect entire pathname, not just new file name
component, when deciding whether to exclude it.
(<fnmatch.h>): Include unconditionally.
(child_open_for_compress): Dup after closing, to avoid possible file
descriptor exhaustion.
(flush_write): Use FILESYSTEM_PREFIX_LEN instead of MSDOS ifdef.
(flush_read): Likewise.
(from_chars): Renamed from from_oct. New parameter specifing
the negative of the minimum allowed value. Support negative
and base-64 values.
(base64_map): New var.
(base64_init): New function.
(print_header): Output numeric uids and gids if numeric_owner_option.
(unlink_destination): New function, which checks for unlink failures.
(maybe_recoverable): Stay quiet if -U.
(extract_archive): Use O_EXCL if unlink_first_option.
Report unlink failures.
Use HAVE_SYMLINK, not S_ISLNK, to determine whether symlink exists.
Use HAVE_MKFIFO || defined mkfifo, not S_ISFIFO, to determine whether
mkfifo exists.
negative timestamps are handled correctly.
Replace invocations of xstrtol and xstrtoul with xstrtoumax, for
uniformity (and so that we don't need to have the other fns).
(main): Remove call to init_total_written; no longer needed.
permissions problems.
(open_archive): Fix wording on fatal error message.
Don't bother to stat /dev/null if the archive is not a character
special device.
MODE_OPTION, NEWER_MTIME_OPTION, NO_RECURSE_OPTION, NULL_OPTION,
OWNER_OPTION, POSIX_OPTION, PRESERVE_OPTION, RECORD_SIZE_OPTION,
RSH_COMMAND_OPTION, SUFFIX_OPTION, USE_COMPRESS_PROGRAM_OPTION,
VOLNO_FILE_OPTION, OBSOLETE_ABSOLUTE_NAMES, OBSOLETE_BLOCK_COMPRESS,
OBSOLETE_BLOCKING_FACTOR, OBSOLETE_BLOCK_NUMBER,
OBSOLETE_READ_FULL_RECORDS, OBSOLETE_TOUCH, OBSOLETE_VERSION_CONTROL):
Make sure they can't be valid chars, so they don't overlap with char codes.
Use an enum instead of a lot of #defines.
(long_options, main, usage): Remove --ending-file option.
(OPTION_STRING): Remove -E.
(ISODIGIT, ISSPACE): Remove; now in system.h.
(read_and): Excise ending_file_option.
(decode_header): No need to AND mode with 07777; MODE_FROM_OCT
does this now.
(from_oct): Cast ISSPACE arg to unsigned char.
(mode_from_oct): Translate modes from external to internal form.
Do not complain about unrecognized mode bits.
(decode_mode): Do not assume mode bits have traditional Unix values.
Do not assume mode bits have traditional Unix values.
(set_mode): Use %04 not %0.4 format.
(extract_sparse_file): Do not use data_block uninitialized.
Check for lseek failures; use portable lseek whence values.
have the same bit patterns.
(start_header): Do not assume mode bits have traditional Unix values.
(finish_sparse_file): Use lseek whence macros instead of integers.
(dump_file): Do not assume mode bits have traditional Unix values.
Do not invoke finish_sparse_file on a negative file descriptor.
(child_open_for_compress, flush_write, flush_read): Use it to write
buffers.
(open_archive): Report error if fstat of archive fails.
Improve efficiency of check for /dev/null.
Also, fix some corner cases with remote archives and /dev/null checking.
(close_archive): Test for input fifo only if not remote.
Truncate output archive only if it's not remote.
Output a trailing NUL unless the value won't fit without it;
this is backward compatible with Unix tar (and with GNU Emacs).
(finish_header): No need to append NUL to chksum, now that
to_oct is doing it.
