cp/mv: add xattr support

2009-01-29T12:26:07Z

(copy_attr_quote): New function to quote file name in error messages printed by libattr. (copy_attr_free): Empty function requested by libattr to free quoted string. (copy_attr_by_fd): New fd-oriented function to copy xattr. (copy_attr_by_name): New name-oriented function to copy xattr. (copy_reg, copy_internal): Call copy_extended_attributes function. * src/cp.c (usage): Mention new --preserve=xattr option. (decode_preserve_arg): Handle new --preserve=xattr option. * src/mv.c: Always attempt to preserve xattr. * src/install.c: Never attempt to preserve xattr. * tests/misc/xattr: New test for xattr support in cp, mv and install. * tests/Makefile.am: Add the new test to list. * doc/coreutils.texi: Mention xattr support, new --preserve=xattr option. * NEWS: Mention the change.

m4: don't use AC_REQUIRE([AC_C_BIGENDIAN])

2009-01-21T13:48:39Z

* m4/jm-macros.m4: Use AC_REQUIRE([gl_BIGENDIAN]) instead. This avoids a subtle problem recently documented in autoconf: http://git.sv.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=34e2c8d5484

improve M4 quoting

2009-01-01T01:15:07Z

* configure.ac: Add quotes. * gl/m4/mgetgroups.m4 (gl_MGETGROUPS): Likewise. * m4/boottime.m4 (GNULIB_BOOT_TIME): Likewise. * m4/check-decl.m4 (gl_CHECK_DECLS): Likewise. * m4/gmp.m4 (cu_GMP): Likewise. * m4/jm-macros.m4 (coreutils_MACROS, gl_CHECK_ALL_HEADERS): Likewise. (gl_CHECK_ALL_TYPES): Likewise. * m4/lib-check.m4 (cu_LIB_CHECK): Likewise. * m4/stat-prog.m4 (cu_PREREQ_STAT_PROG): Likewise. FYI, I first ran this command: git ls-files | grep -E '\.(m4|ac)$' | xargs perl -pi \ -e 's/(AC_[A-Z_]+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_[A-Z_]+\(\[[^,]+?\], )([^,[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_[A-Z_]+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g' Then I updated serial numbers and copyright dates manually. Also, I manually added two pairs of quotes in boottime.m4.

maint: tighten m4 AC_ quoting check

2009-01-01T01:15:07Z

* maint.mk (sc_m4_quote_check): Renamed from m4-check. Also search for AC_DEFINE and AC_DEFINE_UNQUOTED. Also search in configure.ac. * configure.ac: Quote first argument of AC_DEFINE. * jm-macros.m4 (coreutils_MACROS): Quote the first argument to AC_DEFINE.

m4: avoid a warning from gcc's -Wstrict-prototypes

2008-11-30T18:15:51Z

(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.
