coreutils/m4, branch v8.22

build: avoid more selinux build failures

2013-11-27T20:59:23Z

Handle both newer selinux libraries with mode_to_security_class(), and systems without selinux at all. We could easily adjust gnulib to provide the necessary stubs for use by this module, but it's more efficient to just stub out the module completely, when not using selinux. * src/selinux.h: Define stubs for the two module functions, when SELinux is not available. * src/selinux.c: Exclude all logic in preference for the stubs when selinux isn't used. Also when newer selinux libs are used, don't use our conflicting static version of mode_to_security_class(). m4/jm-macros.m4: Check for the system mode_to_security_class().

maint: refactor SMACK interface to a separate module

2013-07-02T08:47:32Z

Consolidate all smack routines and checks in a module. We replace and wrap the most commonly used smack routines, which allows removing ifdefs throughout the code. * gl/lib/smack.h: A new header containing the implementation of the wrapped and replacement routines. Note the is_smack_enabled() routine should be optimized out at compile time when compiled on a system without libsmack. * gl/modules/smack: Describe the new module and move the configure time code here from ... * m4/jm-macros.m4: ... here. * bootstrap.conf: Reference the new module. * src/id.c: Use the routines without ifdefs where possible. * src/ls.c: Likewise. * src/mkdir.c: Likewise. * src/mkfifo.c: Likewise. * src/mknod.c: Likewise.

id: adjust/restrict smack support to newer versions of libsmack

2013-06-20T20:50:57Z

There was slight change to libsmack such that positive values are reserved for returning length of the label for smack_new_label_from_* functions. * m4/jm-macros.m4: Set HAVE_SMACK when both smack_new_label_from_self() and recently added smack_new_label_from_path() are present. The latter's presence indicates the newer API of the former. * src/id.c (main): Check that smack_new_label_from_self() < 0, and not just non-zero.

id: with -Z, show SMACK security context

2013-05-08T10:55:08Z

Adds an optional dependency on libsmack. * m4/jm-macros.m4: Look for the smack library/header. * src/id.c (main): Output the smack context if available. * src/local.mk: Link with libsmack if available. * NEWS: Mention the new feature.

build: fix issues when building with GMP

2013-03-24T02:28:38Z

* m4/gmp.m4 (cu_GMP): Add an extra check that gmp.h is available which is required on one Mac OS X 10.5.8 system at least, where the lib was available but the header wasn't. Also enable our GMP code on systems where GMP is not in a separate lib.

maint: update all copyright year number ranges

2013-01-01T03:51:20Z

Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.

build: support older GMP versions

2012-10-08T22:40:08Z

The new factor code introduced usage of mpz_inits() and mpz_clears(), which are only available since GMP >= 5, and will result in a compile error when missing. * m4/gmp.m4 (cu_GMP): Define HAVE_DECL_MPZ_INITS appropriately. * src/factor (mpz_inits): New function, defined where missing. (mpz_clears): Likewise.

timeout: handle signals more transparently

2012-09-24T14:46:51Z

This was originally attempted in commit v8.12-117-g5a647a0, but reverted before release because of the unreliability of disabling core dumps using setrlimit() on Linux kernels. This new version instead uses prctl() where available to more reliably disable core dumps for the timeout process. * m4/jm-macros.m4: Define HAVE_SETRLIMIT and HAVE_PRCTL. * src/timeout.c (disable_core_dumps): A new function that disables coredumps using prctl or setrlimit if available. (main): If the child exited with a signal and we can disable core dumps, then raise that signal to the timeout process itself, so that callers may also see the signal status. Also print a message indicating when the monitored command dumped core, as that information is lost in the signal propagation through timeout.

maint: move the last coreutils-specific files from lib/ to gl/

2012-09-10T06:58:03Z

Convert the few remaining coreutils-specific files in lib/ to gnulib-style modules under gl/, removing their corresponding .m4 files, since the information recorded in those files is better stored in module-description file in gl/modules/. * bootstrap.conf (gnulib_modules): Add new modules: fd-reopen, buffer-lcm, xfts, strnumcmp. * gl/lib/buffer-lcm.c: Renamed from the file in lib/. * gl/lib/buffer-lcm.h: Likewise. * gl/lib/fd-reopen.c: Likewise. * gl/lib/fd-reopen.h: Likewise. * gl/lib/strintcmp.c: Likewise. * gl/lib/strnumcmp-in.h: Likewise. * gl/lib/strnumcmp.c: Likewise. * gl/lib/strnumcmp.h: Likewise. * gl/lib/xfts.c: Likewise. * gl/lib/xfts.h: Likewise. * gl/modules/buffer-lcm: New module-description file. * gl/modules/fd-reopen: Likewise. * gl/modules/strnumcmp: Likewise. * gl/modules/xfts: Likewise. * m4/fd-reopen.m4: Remove, no longer needed. * m4/strnumcmp.m4: Likewise. * m4/xfts.m4: Likewise. * m4/prereq.m4: Do not AC_REQUIRE the m4 functions from our just-removed m4/*.m4 files.

su: remove program (util-linux is now the best source for it)

2012-06-06T20:33:08Z
