* src/dd.c (MULTIPLE_BITS_SET): New macro, extracted from...
(multiple_bits_set): ...this function.
Use a single-line, and far simpler expression (no need to list all
O_* symbols again) to validate the derived O_FULLBLOCK value.
* src/expr.c (die): New "noreturn" function to wrap one-arg use of
error
(string_too_long): Use die rather than error.
(toint): Remove definition of now-unused function.
(eval6): Remove a little duplication.
Use die rather than error.
(dodivide): Remove declaration of now-unused variable.
* src/Makefile.am (expr_LDADD): Link expr against GNU MP.
* doc/coreutils.texi (expr invocation): Describe --bignum,
--no-bignum. Explain the new arbitrary-precision functionality.
* NEWS: Indicate that arbitrary-precision arithmetic is now
supported in expr.
* src/expr.c (enum valtype): Added mp_integer, signifying a GNU MP
number.
(usage): Document the new options --bignum and --no-bignum which
force and prohibit the use of arbitrary-precision arithmetic,
respectively.
(long_options): data structure for getopt_long, which we need to
use to parse the options mentioned above.
(main): parse these options with getopt_long instead of
parse_long_options.
(valinfo): Downgrade the numeric member of the union from
intmax_t to signed long, since MP lacks functions for promoting an
intmax_t to an arbitrary-precision quantity.
(enum arithmetic_mode): Represents the current choice between
--bignum, --no-bignum and the default (automatically switch from
one to the other if needed).
(integer_overflow): issue a more explicit error message indicating
that MP is not available.
(string_too_long): new function, emits a fatal error message for
the case where an argument to the 'index' expression is too long
for a string offset to be represented.
(int_value): With --bignum, create the value as mp_integer rather
than plain integer.
(substr_value): factored out of eval6; implements "substr".
(freev): also destroy mp_integer values. Check that no mp_integer
values exist if --no-bignum was specified.
(printv, null, tostring): support mp_integer.
(toint): new funtion for converting from string or mp_integer to
integer.
(getsize): extracts a size_t value from a VALUE object; used to
implement substr.
(promote): promotes a value from integer to mp_integer.
(domult, dodivide): functions for multiplication and division,
factored out of eval4.
(doadd): addition/subraction function, factpred out of eval3.
(eval3): support mp_integer types; call doadd.
(eval4): support mp_integer types; call domult, dodivide.
(eval6): support mp_integer offsets and lengths for "substr" and
"index".
* TODO: Mention that expr supports arbitrary-precision arithmetic,
and suggest that this might also be a good idea for seq.
* AUTHORS (expr): Add James Youngman.
* doc/coreutils.texi (uptime invocation): document uptime.
* TODO: uptime is documented now.
* src/uptime.c (print_uptime): Use fprintftime to print the time, rather
than printf. This should make the situation better for translations.
* src/chroot.c (usage): Add "[ARG]" to synopsis.
* src/cut.c (usage): Remove an inconsistent period in an option
description.
* src/du.c (usage): Remove superfluous argument after short option -X.
Also remove inconsistent uppercase and final period.
Use a single indent level for prettiness.
* src/shred.c (usage): Normalize the synopsis.
* src/stty.c (usage): Options -F and --file are alternatives, cannot
both be used.
* src/sum.c (usage): -r does not overrule -s; the last one counts.
* src/uptime.c (usage): Remove inconsistent space from the synopsis.
* src/users.c: Likewise.
* src/true.c (usage): Mark both strings with N_, so that
the one for "false" is also extracted for translation.
For consistency, mark both, although only the latter one needed it.
Inspired by a patch from Benno Schulenberg.
* src/ls.c: [HAVE_CAP] Include <sys/capability.h>.
(has_capability): New function for capability detection.
(print_color_indicator): Colorize file with capability.
* m4/jm-macro.m4: New configure option: --disable-libcap.
Check for libcap usability.
* src/Makefile.am (dir_LDADD, ls_LDADD, ...): Append $(LIB_CAP).
* src/dircolors.c: Update color lists.
* src/dircolors.hin: Mention new CAPABILITY color attribute.
* tests/ls/capability: Test for ls - colorize file with capability.
* tests/Makefile.am (root_tests): Add ls/capability.
* NEWS: Mention the change.
* m4/gmp.m4: New file; adds cu_GMP, which detects GNU MP.
* configure.ac: Use cu_GMP.
* src/Makefile.am: Link factor against libgmp if available.
* src/factor.c: Use GNU MP if it is available.
(emit_factor, emit_ul_factor, factor_using_division,
factor_using_pollard_rho, extract_factors_multi,
sort_and_print_factors, free_factors): new functions
for the arbitrary-precision implementation, taken from an example
in GNU MP.
(factor_wheel): Renamed; was called factor.
(print_factors_single): Renamed; was called print_factors.
(print_factors): New function, chooses between the single- and
arbitrary-precision algorithms according to availability of GNU MP
and the length of the number to be factored.
(usage, main): New options --bignum and --no-bignum.
* coreutils.texi (factor invocation): Document new command-line
options for the MP implementation and update the performance
numbers to take into account the asymptotically faster algorithm.
* TODO: Remove item about factoring large primes (it's done).
* m4/gmp.m4: Add support for --without-gmp.
* NEWS: Mention the new feature.
When printing one name per line and not sorting, ls now uses
constant memory per directory, no matter how many files are in
the directory.
* ls.c (print_dir): Print each file name immediately, when possible.
* NEWS: Mention the improvement.
* src/shuf.c (write_permuted_output): Add EOLBYTE parameter and use
it rather than hard-coding "\n".
(main): Adjust sole caller.
* tests/misc/shuf: Add a test to exercise this bug fix.
* NEWS: Mention it.
* src/dd.c (O_FULLBLOCK): Define using an enum, not #define.
Derive the value, rather than hard-coding to one that might conflict.
(usage): Mention iflag=fullblock in --help output.
(scanargs): Reset the O_FULLBLOCK bit, so that we don't try to set
an undefined attribute via fcntl (fd, F_SETFL, ...
* tests/dd/misc: Signal framework_failure when necessary.
Use "compare actual expected", so any diffs look "right".
* NEWS (dd): Alphabetize and reword.
* coreutils.texi (dd invocation): Adjust wording.
* src/dd.c (iread_fullblock): New function for reading full blocks.
(scanargs): Check for new parameter iflag=fullblock.
(skip): Use iread_fnc pointer instead of iread function.
(dd_copy): Use iread_fnc pointer instead of iread function.
* tests/dd/misc: Add test for dd - read full blocks.
* doc/coretuils.texi: Mention new parameter iflag=fullblock.
* NEWS: Mentioned the change.
* src/ptx.c (fix_output_parameters): Don't let before_max_width
go negative -- that would cause an infloop in define_all_fields.
(main): Don't clobber name[0] with lists of two or more input files.
* tests/misc/ptx: New file. Test for the above.
* tests/Makefile.am (TESTS): Add misc/ptx.
The expand released in current distributions (Fedora Core 4 - Fedora 9
at least), doesn't expand --initial tabs if spaces are present.
tests/misc/expand: Add test to verify --initial works correctly
with lines starting with both spaces and tabs.
Without this, test-related variable settings were not exported to
the shell_or_perl_ function when using dash or Solaris 11's /bin/sh.
* tests/check.mk (TESTS_ENVIRONMENT): Use an explicit "export",
so as not to rely on non-POSIX behavior of some /bin/sh (e.g.,
bash-based ones).
* src/who.c (print_runlevel): Print last=%c only when the "preceding
run-level" byte is printable. Reported by Gian Piero De Lolliis in
<http://bugzilla.redhat.com/453249>.
Without this, `truncate -s '> -1' F` would truncate F to length 0,
and `truncate -s " +1" F` would truncate F to 1 byte. Now, each
elicits a diagnostic.
* src/truncate.c: Skip leading white space in the --size option
argument and any white space after one of the relative modifiers,
so that the presence of a +/- modifier can be detected reliably.
* tests/misc/truncate-parameters: Add tests for the above.
* tests/misc/timeout-parameters: Remove test for invalid
signal number (we don't know what signal numbers are
invalid on all systems). Also tweak the other invalid
signal check so that the rest of the arguments are correct.
