stat,tail: improve support for hostfs and smackfs

2013-12-13T14:05:53Z

hostfs is provided by the Linux UML subsystem. smackfs is provided by the Linux Smack security module. * src/stat.c (human_fstype): Add new file system ID definitions. * NEWS: Mention the improvement, and adjust for the fact that SNFS is a remote file system.

tail: use consistent diagnostics with and without inotify

2013-12-09T09:26:17Z

* src/tail.c: With inotify, when a file is initially absent, we fstat(-1) for that file spec, thus recording an errnum of EBADF, which caused the "has become accessible" diagnostic to be issued, when the file first appears. Instead we avoid the fstat(-1) and thus emit the more natural and consistent "has appeared" diagnostic. * tests/tail-2/retry.sh: Use the new diagnostic which also causes this test to pass on systems without inotify.

shuf: --repeat, not --repetitions; default --head-count is infinity

2013-12-06T17:55:55Z

Original problem reported by Philipp Thomas in . * NEWS: shuf --repeat, not shuf --repetitions. * doc/coreutils.texi (shuf invocation): * src/shuf.c (usage, long_opts, main): * tests/misc/shuf.sh: Likewise. Also, the default head-count is infinity.

selinux: fix --context=CTX for cp and diagnose defaultcon() errors

2013-12-05T00:18:36Z

* src/selinux.h (ignorable_ctx_err): A new function used to determine if a warning should be given after a call to defaultcon() or restorecon(). * src/cp.c (main): Fix the setfscreatecon() call to use the argument passed by the user. * src/mkdir.c (make_ancestor): Show all but "ignoreable" errors from defaultcon() and restorecon(). * tests/misc/selinux.sh: Add a test run as root in selinux enforcing mode, to ensure cp --context=invalid is honored and fails immediately.

md5sum, sha*sum: use libcrypto where available

2013-12-04T13:18:56Z

libcrypto is generally available and has well optimized crypto hash routines particular to various systems. For example, testing sha1sum with openssl-1.0.0j on an i3-2310M, gives a performance boost of about 40%: $ time sha1sum.old --tag ~/test.iso SHA1 (/home/padraig/test.iso) = 3c27f7ed01965fd2b89e22128fd62dc51a3bef30 real 0m4.692s user 0m4.499s sys 0m0.162s $ time sha1sum.new --tag ~/test.iso SHA1 (/home/padraig/test.iso) = 3c27f7ed01965fd2b89e22128fd62dc51a3bef30 real 0m2.685s user 0m2.512s sys 0m0.170s * configure.ac: By default, enable use of libcrypto if available. * src/local.mk: Link with libcrypto. * NEWS: Mention the md5sum and sha*sum improvements.

df: handle bind mounts when processing device nodes

2013-12-04T13:17:17Z

* src/df.c (get_disk): Use the same heuristic used in get_point() to select the shortest file system mount point, in an attempt to show the base mounted file system. * NEWS: Mention the bug fix.

df: dereference symlinks to disk device nodes

2013-12-04T13:16:27Z

This is so the matching for the device is done on the canonical name of the disk node, rather than on the path of the symlink. In any case the user will generally want to use the symlink target. * src/df.c (get_disk): Canonicalize the passed file, before matching against the list of mounted file system devices. Note we pass the original symlink name to the "file" output field, as the symlink target is usually available through the "source" field. * tests/df/df-symlink.sh: Test the dereferencing operation. * tests/local.mk: Mention the new test. * NEWS: Mention the fix.

maint: avoid '%s' quoting notation in diagnostic messages

2013-12-03T09:03:51Z

Add a new rule to ensure the use of quote() instead of '%s' or `%s' in format strings of diagnostics messages. * cfg.mk (sc_prohibit_quotes_notation): Add rule. * TODO: Remove the entry regarding the '%s' notation. * src/mkfifo.c (main): Remove the offending and in this case even duplicate quoting in the format string of the error diagnostic. * src/mknod.c (main): Likewise. * src/df.c (decode_output_arg): Change two invocations of error() according to the above new rule. * src/numfmt.c: Fix numerous wrong quote notations to fit the above new rule, mostly in internal debugging diagnostic messages.

build: fix potential factor build failure on arm and powerpc

2013-11-29T15:23:54Z

* src/longlong.h: Sync with the latest longlong.h from libgmp to: - avoid arm asm when being compiled for the thumb instruction [sub]set - avoid old powerpc assembly that is incompatible with newer GCC - add arm64 optimized count_trailing_zeros() - add sparc64 optimized add_ssaaaa() and umul_ppmm()

maint: remove various FIXME comments

2013-11-29T12:08:44Z

* src/extent-scan.c (extent_need_sync): Remove the FIXME comment about removing the work around. As discussed in [1], the needed FIEMAP fix never made it into the Linux kernel. * src/realpath.c (longopts): Remove the FIXME comment about deprecating the --strip option as it's a valid alias for --no-symlinks option. Also discussed in [1]. [1] http://lists.gnu.org/archive/html/coreutils/2013-11/msg00103.html
