FreeBSD 2.0.5 macro definition. Reported by David O'Brien
(obrien@sea.legent.com).

This is a minor concession to POSIX which says `no output shall be produced'.
(main): Fix -k so it works. -k 2,3 was being treated like -k 2.
Reported by Marcus Daniels <marcus@sysc.pdx.edu>.

relative to the initial input file pointer position, not
necessarily from the beginning of the file.
[!from_start]: Don't back up past the initial position of the
input file pointer.
(tail_lines): Call file_lines only if FD refers to a regular file
with its file pointer positioned at beginning of file. Otherwise,
call pipe_lines. This is a kludge. Once there's a decent test
suite, fix this properly.
Before, (echo 1; echo 2) > k; sh -c 'read x; tail' < k
would output both lines of the input file even though the first had
already been read. Reported by John Roll (john@panic.harvard.edu).

(md5_file, md5_check): Set it.
(main): Use it.
[OPENOPTS]: Depend explicitly on BINARY.
(md5_file): Take a new parameter, MD5_RESULT, and no longer
generate output.
(md5_check): Invoke md5_file instead of calling fopen directly.
When giving a diagnostic for a line with invalid format, also report
the line number.
(main): Generate output after a successful md5_file call.
[in many places]: Upon detection of an error, rather than exiting
immediately, issue a diagnostic, note that an error occurred and
exit later.

issue the usage message; also report why.

(main): Call the new function instead of doing all that in an if stmt.
Always use "%s" format rather than raw filename as format argument
in printf-style functions like error. Otherwise, filenames containing
e.g. `%s' lose.
Remove all traces of `old format'. There is only one format now.
The compatible one.
|
|
(main): Report an error if md5_stream fails. Otherwise, running
`md5sum dir-on-mounted-filesystem' always reported the checksum
for an empty file. Now it gets the `is a directory' error.
Greg McGary reported that the released version got stuck in an
infinite loop with such arguments.
|
|
Properly handle file names with leading and trailing white space.
|
|
|
|
Reformat paragraph so line with new FSF address fits in 80 columns.
|
|
Fiddle comments.
|
|
|
|
(main): Rename local variable.
Add FIXME: allow newlines in filenames.
Detect and report failed fclose calls on stdout and checkfile_stream.

be of type size_t, not int.
(main): Declare NR and CHARS_READ to be of type long, not int.
|
|
(append_range): Declare FIRST and LAST parameters to be unsigned int,
not size_t.
(find_closing_delim): Clean up interface, separating boolean success
indicator and index.
(find_bracketed_repeat): Likewise.
(build_spec_list): Adapt to use new interfaces.

call to tail_lines. Otherwise, NetBSD lost because N_UNITS (of type
off_t, a 64-bit type on NetBSD) wasn't converted to the target type,
long. Reported by Dan Hagerty (hag@gnu.ai.it.edu).

omission of field spec only when character offset is specified.
Otherwise, -. +. would be accepted.
|

position specification. Omitting M is equivalent to specifying `0'
for M. From Rick Sladkey (jrs@world.std.com).

Before, running `printf 1234| ./od --width=4 --read-bytes=4'
printed output for 8 bytes -- the last four were garbage.
This happened only when the dump limit, N, was specified (with
--read-bytes=N) and N was a multiple of bytes_per_block
(usually 16, but 4 in this example). From Andreas Schwab.
|
|
(main): Write (de facto) standard Plumb/Lankester format.
New option: --quiet.
Check option no longer takes an argument.
When checking, exit status reflects success.
|

silently overflow, accepting a group id larger than INT_MAX.
(isnumber): Remove now-unused static function.
(change_file_group) [MAXUID]: Give a more descriptive message
when numeric group id is larger than MAXUID.

it away for compilers that don't grok it.

on systems.
|
|
conflict with max macro from some system's header files and bad pre-ANSI
compilers.
|
|
also check `unsigned long', as a concession to systems with
int's smaller than 32 bits.

headers that have a different prototype for `join' get an error.
|
|
headers that define `word' to be a type get syntax errors because
of the variable by the same name.

error in sa_handler assignment.

Edzer Pebesma <Edzer.Pebesma@rivm.nl>.

individual local variables before performing computation on them,
then copy results back into returned struct. Solely for better
optimization by compilers that can't keep struct members in
registers. From Ulrich Drepper.
|
|
(hex_digits): Unprotoize.
(main): Interpret `no file args' as request to read from stdin.
(usage): Reflect that change.
|
|
Don't use #elif. Some older compilers don't grok it.
(split_3): New function to parse out sum, flag, and filename
when reading check file.
(hex_digits): Remove length parameter since string parameter is
now nul-terminated.
(main): Don't allocate separate arrays for filename and sum
when checking. Get pointers into line buffer with split_3 instead
of using sscanf.
|
|
[__P]: Undefine it.
[UNIX || unix]: Also test __UNIX__, __unix__,
and _POSIX_VERSION. Reported by Arne H. Juul.
