after handling them.
(list_archive): Use consistent message for unexpected EOF.
Use error message functions to report errors consistently.
(read_header): Use xalloc_die to report memory exhaustion.
Use consistent message for unexpected EOF.
(decode_mode): Remove; moved to misc.c.
(skip_file): Use consistent message for unexpected EOF.
(skip_extended_headers): Likewise.
Quote arbitrary strings in diagnostics.
(from_header): Use locale_quoting_style to quote diagnostics.
(print_header, print_for_mkdir): Quote with quotearg, not quote_copy_string.
(base_64_digits): Moved here from create.c.
(base64_map): Use UCHAR_MAX for size, not less-clear (unsigned char) -1.
(read_and): Don't get time from header unless we need it now;
as getting time can cause duplicate diagnostics if bogus.
Remove "Hmm, " from diagnostic.
Use "Skipping to next header" uniformly.
(from_header): Renamed from from_chars. All uses changed.
Allow different forms for unportable 2's complement numbers.
Don't check for extended forms when parsing checksums.
Parse base-256 output.
(gid_from_header): Renamed from gid_from_chars. All uses changed.
(major_from_header): Renamed from major_from_chars. All uses changed.
(minor_from_header): Renamed from minor_from_chars. All uses changed.
(mode_from_header): Renamed from mode_from_chars. All uses changed.
(off_from_header): Renamed from off_from_chars. All uses changed.
(size_from_header): Renamed from size_from_chars. All uses changed.
(time_from_header): Renamed from time_from_chars. All uses changed.
Warn about future timestamps.
(uid_from_header): Renamed from uid_from_chars. All uses changed.
(uintmax_from_header): Renamed from uintmax_from_chars. All uses changed.
(tartime): New function, incorporating isotime.
(isotime): Delete.
(print_header): Use tartime.
(isotime): Now takes time_t, not time_t *. Report the decimal values
of times that can't be broken down.
(print_header): Don't assume that major and minor device numbers can
fit into uintmax_t.
(read_header): Fix computation of signed checksums on machines where
char is unsigned.
Do not consider a block to be zero unless all its bytes are zero,
even the checksum bytes. Do not attempt to parse the checksum of
a zero block. Fix memory leak with long names and links.
(from_chars): Accommodate a buggy tar that outputs leading NUL
if the previous field overflows.
(skip_extended_headers): Don't assume find_next_block yields nonnull.
Don't assume years fit into four digits.
Don't append trailing newline.
(print_header): Report ??? if localtime returns null;
Don't assume years fit into four digits.
(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.
(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.
(from_oct): Add forward decl.
(read_header): Return HEADER_FAILURE if we can't parse the checksum.
(from_oct): Report an error only if TYPE is nonzero.
Quote any funny characters in bad header.
size_from_oct, time_from_oct, uid_from_oct, uintmax_from_oct):
Use TYPE_MAXIMUM instead of macros like OFF_MAX, which are not reliable
(e.g. OFF_MAX in AIX 4.2 is incorrect).
print_for_mkdir): Use mode_t, off_t, size_t when appropriate. Remove
now-useless casts. Use unsigned long to print *_t types, except use
STRINGIFY_BIGINT for off_t.
(read_header): Check for overflow when converting header size.
(from_oct): Now static. Now returns uintmax_t. `where' arg is now
const char *. Size arg is now size_t. Now takes new type and maxval
args. Compute result using uintmax_t, not long. Report error if
field does not contain octal number in range.
(gid_from_oct, major_from_oct, minor_from_oct, mode_from_oct,
off_from_oct, size_from_oct, time_from_oct, uid_from_oct,
uintmax_from_oct): New functions.
(stringify_uintmax_t_backwards): New function.
(decode_mode, print_for_mkdir): Mode arg is now mode_t.
(skip_file): Offset arg is now off_t.
