zero-length arrays. Instead, use sizes of -1 or +1.
|
|
(ulonglong_t): Move declaration to precede new use.
[enum size_spec] (N_SIZE_SPECS): New member.
(width_bytes): Add initializer corresponding to ulonglong_t type.
(struct assert_width_bytes_matches_size_spec_decl): Declare.
Based on a patch from Tony Kocurko.
|
|
(usage): Document only the intersection of the old and new behaviors,
to encourage portability.
(short_options): Remove; no longer needed.
(COMMON_SHORT_OPTIONS): New macro.
(STRINGS_OPTION, WIDTH_OPTION): Remove; no longer needed.
All uses changed to back to the corresponding short options.
(main): Parse options using POSIX 1003.1-2001 rules if
conforming to that standard. Do not warn of obsolete options.
|
|
support of obsolete "-N" option syntax in expand, head, fold,
split, tail, unexpand, uniq, and which prohibits options with
optional arguments in od and pr.
(usage): Document it.
(main): Check for obsolete options.
(short_options): New constant.
New enum for long options.
|
|
fseeko's seek argument is already known to be in range,
since it is less than the file size.
|
|
|
|
(Also, check for overflow when converting uintmax_t to off_t.)
|
|
|
|
HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION.
|
|
instead of hard-coding --help and --version descriptions.
|
|
Split usage strings so that --help and --version descriptions are alone
in their own string.
Likewise for the one that says:
Mandatory arguments to long options are mandatory for short options too.
|
|
|
|
|
|
Use fputs, not printf.
|
|
``Mandatory arguments to long options are mandatory for short options too.\n\''

n_bytes_to_skip, skip, format_address_none,
format_address_std, format_address_paren,
format_address_label, write_block, parse_old_offset, dump,
dump_strings, main):
Use uintmax_t, not off_t, for file addresses, so that we can
handle multiple large files even if the sum of their sizes
exceeds off_t limits.
(print_s_char, print_char, print_s_short, print_short,
print_int, print_long, print_long_long, print_float,
print_double, print_long_double, dump_hexl_mode_trailer,
print_named_ascii, print_ascii, decode_one_format):
Use size_t, not off_t, for in-memory byte counts.
(end_offset): New var.
(dump, dump_strings): Use it.
(main): Set it, but check for overflow while doing so.
(skip): Report an error if an in-range lseek fails on a
regular file, as something's seriously wrong. Check for
negative regular file sizes (possible with some broken NFS
implementations).
(parse_old_offset): Now all offsets are valid, so return a
success boolean and take a pointer to an offset as an argument.
All callers changed.
(dump_strings): Check for overflow when computing end_offset -
string_min.
(main): Remove OFF_T_MAX checks that are no longer needed.
Don't bother assigning through temporary when there's no size
limit to check.
|
|
(skip): Revert part of last change: use lseek, not fseek.

the standard I/O library. Otherwise, od would read more input
than requested. This could have caused problems when reading
from pipes, character devices, and open file descriptors inherited
from a parent process.
* src/od.c (open_next_file): New function, factored out of...
(skip): Adapt to use open_next_file.
(read_char): Likewise.
(read_block): Likewise.
(main): Likewise.
(dump): Fix an off-by-one error that could have made od fail to
report a read error when reading from a named file (not stdin).
(check_and_close): Account for the fact that in_stream may now be NULL.
(usage): Correct descriptions of -j and -N options.
Patch by Ian Bruce.

(LONGEST_INTEGRAL_TYPE): Remove definition.
(MAX_INTEGRAL_TYPE_SIZE): Use ulonglong_t instead of LONGEST_INTEGRAL_TYPE.
(print_long_long): Compile this function even on systems without
long long support.
(decode_one_format): Remove #if directive.
|
|
`#if HAVE_UNSIGNED_LONG_LONG'. From Darren Salt.
Change all `#ifdef HAVE_UNSIGNED_LONG_LONG' to use `#if' instead.

(output_address_fmt_string, address_fmt_buffer, address_pad): Remove.
(flag_pseudo_start): Now int, not long int.
(pseudo_offset): Now off_t, not long int.
(n_specs, n_specs_allocated): Now size_t, not unsigned int.
(format_address, format_address_none, format_address_std,
format_address_label): Now accepts an extra char argument (an extra
char to print if nonzero), and prints instead of returning a string.
All callers changed.
(bytes_per_block): Now size_t, not int.
(format_address_none): Do not even print the extra char argument.
This simplifies the callers.
(format_address_std, format_address_label): Print off_t ourself
instead of trying to use autoconfigured format. This is faster and
more portable.
(format_address_paren): New function.
(dump): Remove unnecessary cast.
(expand_address_fmt): Remove.
(main): Use size_t, off_t, etc. instead of builtin types where this is
advisable. Adjust to above changes. Remove unnecessary cast.

(MAX_ADDRESS_LENGTH): Don't hard-code as a literal.
Rather, define in terms of the type, off_t.
(string_min): Declare to be of type size_t.
(flag_dump_strings): Declare to be of type int.
(print_s_char): Declare the n_bytes parameter and the local, `i',
to be of type off_t.
(print_char): Likewise.
(print_s_short): Likewise.
(print_short): Likewise.
(print_int): Likewise.

(dump_hexl_mode_trailer): Likewise.
(print_named_ascii): Likewise.
(print_ascii): Likewise.
(write_block): Likewise.
(print_ascii): Declare local, `print_function' with a prototype.
Change a few `>' comparisons to the equivalent `<' form.
(parse_options): Declare `tmp' to be of type uintmax_t.
Use xstrtoumax, not xstrtoul.
Fail if the specified offset if larger than OFF_T_MAX.
(dump_strings): Declare local `i' to be of type size_t.
Remove the now-unnecessary cast-to-off_t.
(main) [IF_LINT]: Initialize desired_width to avoid a warning.
Declare `tmp' to be of type uintmax_t.
Use xstrtoumax, not xstrtoul.
Fail if minimum string length is larger than SIZE_MAX.
Fail if specified width is larger than ULONG_MAX.

(format_address): Use off_t, not long unsigned_int as the
parameter type.
(format_address_none): Likewise. Mark parameter as unused.
(format_address_std): Likewise.
(format_address_label): Likewise.
(print_ascii): Mark format string parameter as unused.
(write_block): Use off_t, not long unsigned_int as offset type.
(expand_address_fmt): New function.
(main): Use it to expand each address format string template.

This should be portable, as we seek before doing any I/O.
(fseeko): Remove; no longer used.
|
|
|
|
Add support for printing data as unsigned
long long integers.
|
|
|
|
(main): Likewise.
|

* src/sys2.h (MIN, MAX): Define here instead.

[long_options]: Remove the "help" and "version" entries.
Remove declarations of show_help and show_version.
(main): Use parse_long_options, including author name(s).
Remove the show_version and show_help blocks.

stream to binary mode.
|
|
|
|
|
|
|
|
Remove definitions of those symbols.
* src/csplit.c: Move inclusion of regex.h/rx.h to follow system.h
since it now includes limit.h which defines RE_DUP_MAX.
* src/nl.c: Likewise.
* src/tac.c: Likewise.

(skip): Use fseeko if available. Don't use lseek; it causes
the stdio stream to become out of sync with respect to the
underyling file descriptor.
From Paul Eggert.

(decode_format_string): Cast first arg of xrealloc to char*.
