struct statfs has the f_frsize member since Linux 2.6,
so use that rather than f_bsize which can be different.
Note the related df change mentioned in NEWS is handled
in gnulib by using statvfs() rather than statfs()
on Linux > 2.6.36 (where statvfs doesn't hang) and the
same method as stat for Linux 2.6 kernels earlier than that.
stat(1) doesn't use statvfs() on GNU/Linux as the f_type
member isn't available there.
Note the change to not use statvfs() on GNU/Linux was introduced
in gnulib commit eda39b8 16-08-2003.
* m4/stat-prog.m4 (cu_PREREQ_STAT_PROG): Check for the f_frsize
member in the statfs structure.
* src/stat.c: Use (struct statfs).f_frsize if available.
* NEWS (Bug fixes): Mention this stat fix, and the related df fix
coming in the next gnulib update.
* THANKS.in: Add Nikolaus.
Reported and Tested by Nikolaus Rath
* bootstrap.conf (gnulib_modules): Add sys_resource.
* src/sort.c: Remove #if HAVE_SYS_RESOURCE_H guard around inclusion
of <sys/resource.h> and move the inclusion "up" into the alphabetized
list of its peers. This also avoids a failure of the
sc_prohibit_always_true_header_tests syntax-check rule.
* m4/jm-macros.m4 (gl_CHECK_ALL_HEADERS): Remove sys/resource.h.
This change affects only systems that have neither *at function support
nor the /proc/self/fd support required to emulate those *at functions.
* src/remove.c (write_protected_non_symlink): Call faccessat
unconditionally. Thus we no longer need euidaccess_stat, which was
the sole function used here to operate on a full relative file name.
Remove full_name parameter and update caller.
* lib/euidaccess-stat.h: Remove file.
* lib/euidaccess-stat.c: Likewise.
* m4/euidaccess-stat.m4: Likewise.
* po/POTFILES.in: Remove lib/euidaccess-stat.c.
* m4/prereq.m4 (gl_PREREQ): Don't require gl_EUIDACCESS_STAT.
Prompted by a report from Bruno Haible that the rm/deep-2
test was failing on HP-UX 11.31.
See http://thread.gmane.org/gmane.comp.gnu.coreutils.general/1748
Interix provides faster replacements for getgr{gid,nam,ent} where
group member information is not fetched from domain controllers.
This makes 'id' usable on domain controlled interix boxes.
* m4/jm-macros.m4: Check for _nomembers functions.
* src/system.h: Redefine function to _nomembers when available.
* src/stat.c (USE_STATVFS): Adjust definition so that it is enabled
also on AIX 7.x systems that provide statvfs64 and no statvfs.
[USE_STATVFS && ! STAT_STATVFS && STAT_STATVFS64] (STATFS): Define
to statvfs64 in that precise case.
* m4/stat-prog.m4 (cu_PREREQ_STAT_PROG): Adjust the condition
here to match the new one in stat.c, to keep them in sync.
Reported by Bruno Haible. For details, see
http://article.gmane.org/gmane.comp.gnu.coreutils.general/1668
* m4/jm-macros.m4 (coreutils_MACROS): Use fdatasync only if declared.
MacOS X 10.7 has an fdatasync that is not declared, and is rumored to
be ineffective. (Bug#9141)
* m4/jm-macros.m4: Define HAVE_SETRLIMIT.
* src/timeout.c: If the child exited with a signal,
raise that signal to the timeout process itself,
so that callers may also see the signal status.
Use setrlimit to disable core dumps for the timeout
process, which would be generated by some signals.
With it, we can remove the two sole tests of HAVE_TERMIOS_H.
* bootstrap.conf (gnulib_modules): Add termios.
* src/ls.c: Don't test HAVE_TERMIOS_H.
* src/stty.c: Likewise.
* m4/jm-macros.m4 (gl_CHECK_ALL_TYPES): Remove configure-time
test for termios.h.
* lib/Makefile.am (libcoreutils_a_SOURCES): Remove xmemxfrm.c,
xmemxfrm.h.
* lib/memxfrm.c, lib/memxfrm.h, lib/xmemxfrm.c, lib/xmemxfrm.h: Remove.
* m4/memxfrm.m4: Likewise.
* m4/prereq.m4 (gl_PREREQ): Remove gl_MEMXFRM.
* po/POTFILES.in: Remove lib/xmemxfrm.c.
* src/sort.c: Don't include xmemxfrm.h.
(cmp_hashes): Remove.
(xstrxfrm): New function.
(compare_random): If a line contains NULs, don't create a big
buffer that contains the strxfrm output of each string in the line.
Instead, accumulate checksums and differences as we go, so that
at any one time we have to store at most the output of a single
strxfrm call when processing the line. This removes the need for
an memxfrm function.
* bootstrap.conf: Include the new module
* gl/lib/fadvise.c: Provide a simpler interface to posix_fadvise.
(fadvise): Provide hint to the whole file associated with a stream.
(fdadvise): Provide hint to the specific portion of a file
associated with a file descriptor.
* gl/lib/fadvise.h: Redefine POSIX_FADV_* to FADVISE_* enums.
* gl/modules/fadvise: New file.
* m4/jm-macros.m4: Remove the no longer needed posix_fadvise check.
* .x-sc_program_name: Exclude test-fadvise.c from this check.
* gl/tests/test-fadvise (main): New test program.
* gl/modules/fadvise-testss: A new index to reference the tests.
* src/sort.c (stream_open): Use the new interface.
* src/dd.c (iwrite): Likewise.
* m4/jm-macros.m4 (ARGMATCH_DIE): Use usage(EXIT_FAILURE), not usage(1).
* .x-sc_prohibit_magic_number_exit: Remove *.m4 exemption that was
masking the above.
Tell the system that we'll access input sequentially,
so that we more efficiently process uncached files in a few cases:
Reading from faster flash devices. E.g. 21 MB/s key:
NORMAL 31.6s (26.8 user)
SEQUENTIAL 27.7s
WILLNEED 27.7s
Processing in parallel with readahead when using a small 1M buffer:
NORMAL 24.7s (21.1 user)
SEQUENTIAL 22.7s
WILLNEED 25.6s
A small benefit when merging:
NORMAL 25.0s (16.9 user)
SEQUENTIAL 24.6s (16.6 user)
WILLNEED 38.4s (13.1 user)
Note WILLNEED is presented above for comparison to show it
has some unwanted characteristics due to its synchronous
prepopulation of the cache. It has a good benefit on a
mechanical disk @ 80MB/s and a multicore system with
competing processes:
NORMAL 14.73s
SEQUENTIAL 10.95s
WILLNEED 05.22s
However the scheduling differences causing this result
are probably best explicitly managed using `nice` etc.
* m4/jm-macros.m4 (coreutils_MACROS): check for posix_fadvise().
* src/sort.c (fadvise_input): A new function to apply
the POSIX_FADV_SEQUENTIAL hint to an input stream.
(stream_open): Call the above function for all input streams.
Enabled when coreutils is configured with --with-tty-group.
Based on a patch written by Piotr Gackiewicz. Details at
http://bugzilla.redhat.com/454261
* src/who.c (is_tty_writable): A new function returning true if a TTY
device is writable by the group. Additionally it checks the group to be
the same as TTY_GROUP_NAME when compiled with --with-tty-group.
* m4/jm-macros.m4: Introduce a new configure option --with-tty-group.
* NEWS: Mention the change.
Configure is supposed to detect insufficient XATTR support.
However, if a system has the required headers, but no library,
the configure script would mistakenly enable USE_XATTR.
* m4/xattr.m4 (gl_FUNC_XATTR): If the attr_copy_file function
is not found, don't set USE_XATTR.
Nelson Beebe reported a link failure on RHEL 5.3.
Also, do not let the combination of --disable-xattr and
a stray LIB_XATTR environment setting perturb the build.
* NEWS (Build-related): Mention it.
* README-hacking: Suggest to use ./configure --quiet so that
any warnings are easily noticed.
* m4/gmp.m4 (cu_GMP): Warn if libgmp is not available.
* m4/jm-macros.m4 (coreutils_MACROS): Normalize the libcap warning.
* m4/xattr.m4 (gl_FUNC_XATTR): Warn if libattr is not available.
Setting the envvars, LIB_FDATASYNC, LIB_XATTR or LIB_CRYPT
could cause a configure-time and/or build-time malfunction.
Typically, a configure-time function-in-library test is performed
via code like this:
LIB_VAR=
AC_SUBST([LIB_VAR])
prefix_saved_LIBS=$LIBS
AC_SEARCH_LIBS([FUNC], [LIB_NAME],
[test "$ac_cv_search_FUNC" = "none required" ||
LIB_VAR=$ac_cv_search_FUNC])
LIBS=$prefix_saved_LIBS
However, in each of the files affected by this change, the LIB_VAR=
initialization was omitted. Thus, when set in the environment, its
value would propagate into generated Makefiles when FUNC is not found
in LIB_NAME.
* m4/jm-macros.m4 (coreutils_MACROS): Initialize AC_SUBST'd var
* m4/lib-check.m4 (cu_LIB_CHECK): Likewise.
* m4/xattr.m4 (gl_FUNC_XATTR): Likewise.
* src/copy.c (utimens_symlink): Simplify by using lutimens.
* m4/jm-macros.m4 (coreutils_MACROS): Drop utimensat; gnulib does
this for us.
* tests/cp/preserve-slink-time: Recognize lutimes support.
* bootstrap.conf (gnulib_modules): Add faccessat. Replace strdup
with strdup-posix.
* m4/jm-macros.m4 (coreutils_MACROS): Revert previous change, now
that gnulib does it for us.
* src/remove.c (write_protected_non_symlink): Use faccessat in
more situations.
where N is the depth of the deepest hierarchy rm is processing.
* src/remove.c (write_protected_non_symlink): Use faccessat to
avoid O(N)-per-entry cost of calling euidaccess.
* m4/jm-macros.m4 (coreutils_MACROS): Check for faccessat.
* NEWS (Improvements): Mention it.
* m4/jm-macros.m4 (coreutils_MACROS): The code to handle configure-time
enabling or disabling of libcap support was broken. It would treat any
libcap configure option as --disable-libcap because it doesn't check
$enableval at all. This change makes sure we do the sane thing:
--disable-libcap -> disable and don't run any tests
--enable-libcap -> run tests and fail if not found
default -> run tests and warn if not found
* src/copy.c (utimensat_if_possible): New function.
(copy_internal): Remove variable, "preserve_metadata".
Replace with "dest_is_symlink". That covers all cases but one:
the one in which cp --link has created hard links to non-directories.
In that case, there is no need to update attributes of the links.
Use utimensat_if_possible, to preserve timestamps of symlinks.
* NEWS (New features): Mention this.
* tests/Makefile.am (TESTS): Add cp/preserve-slink-time.
* tests/cp/preserve-slink-time: New file.
* m4/jm-macros.m4 (coreutils_MACROS): Test for utimensat.
Reported in http://bugzilla.redhat.com/230866
* m4/jm-macros.m4: Pull in SELinux libraries while checking for
matchpathcon_init_prefix (). Emit configure warning when not found
with SELinux enabled.
* NEWS (Bug fixes): Mention it.
The bug was introduced in coreutils-7.0 via commit 0647f3eb, 2008-06-02,
"accommodate older SELinux which lacks matchpathcon_init_prefix".
* gnulib: Update submodule to get latest maint.mk.
* Makefile.am (update-copyright): Remove rule; now it's in maint.mk.
* m4/check-decl.m4: Update sole remaining copyright year list.
* build-aux/update-copyright: Handle the case in which "\n#"
appears between the final year number and the copyright holder name.
* m4/lib-check.m4: Update copyright year list.
Reported by Joel E. Denny.
* NEWS: Document the new feature.
* m4/jm-macros.m4: Check if inotify is present.
* src/tail.c (tail_forever_inotify): New function.
(main): Use the inotify-based function, if possible.
* tests/Makefile.am: Add new tests for tail.
* tests/test-lib.sh (require_proc_pid_status_, get_process_status_):
New functions.
* tests/tail-2/pid: New file.
* tests/tail-2/wait: New file.
* tests/tail-2/tail-n0f: Refactor code into the test-lib.sh
require_proc_pid_status_ function.
