2016-09-09cp: use FICLONE instead of BTRFS_IOC_CLONEPaul Eggert
This doesn't affect the generated code on my system; it's merely a cleaner way to use the recently-introduced Linux-specific API. * m4/jm-macros.m4 (gl_CHECK_ALL_HEADERS): Check for linux/fs.h. * src/copy.c: Include <linux.fs.h> if available. (FICLONE) [__linux__]: Define if not already defined. (clone_file): Use FICLONE instead of the older BTRFS_IOC_CLONE, as this ioctl is no longer btrfs-specific.
2016-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * gnulib: Update to latest with copyright year adjusted. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * tests/sample-test: Adjust to use the single most recent year.
2015-07-01numfmt: increase precision on 32 bit FreeBSDPádraig Brady
* m4/jm-macros.m4 (HAVE_FPSETPREC): Define if needed. * src/numfmt.c (main): Call fpsetprec() if needed. Fixes large-15 and large-16 test failures on 32 bit FreeBSD.
2015-01-28sync: support syncing specified argumentsGiuseppe Scrivano
* m4/jm-macros.m4 (coreutils_MACROS): Check for syncfs(). * man/sync.x: Add references to syncfs, fsync and fdatasync. * doc/coreutils.texi (sync invocation): Document the new feature. * src/sync.c: Include "quote.h". (AUTHORS): Include myself. (MODE_FILE, MODE_DATA, MODE_FILE_SYSTEM, MODE_SYNC): New enum values. (long_options): Define. (sync_arg): New function. (usage): Describe that arguments are now accepted. (main): Add arguments parsing and add support for fsync(2), fdatasync(2) and syncfs(2). * tests/misc/sync.sh: New (and only) test for sync. * tests/local.mk: Reference the new test. * AUTHORS: Add myself to sync's authors. * NEWS: Mention the new feature.
2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-10-15cp: avoid speculative preallocation with --sparse=alwaysPádraig Brady
With --sparse=always use fallocate(...PUNCH_HOLE...) to avoid any permanent allocation due to speculative preallocation employed by file systems such as XFS. * m4/jm-macros.m4: Check for <linux/falloc.h> and fallocate(). * src/copy.c (punch_hole): A new function to try and punch a hole at the specified offset if supported. (create_hole): Call punch_hole() after requesting a hole. (extent_copy): Likewise. * NEWS: Mention the improvement.
2014-01-21build: suppress an erroneous warning --with-selinux=noPádraig Brady
* m4/jm-macros.m4: Don't check the SELinux cached variables --without-selinux. Reported-by: Bernhard Voelker
2014-01-02maint: update all copyright year number rangesBernhard Voelker
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.
2013-11-27build: avoid more selinux build failuresPádraig Brady
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().
2013-07-02maint: refactor SMACK interface to a separate modulePádraig Brady
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.
2013-06-20id: adjust/restrict smack support to newer versions of libsmackJarkko Sakkinen
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.
2013-05-08id: with -Z, show SMACK security contextJarkko Sakkinen
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.
2013-01-01maint: update all copyright year number rangesJim Meyering
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.
2012-09-24timeout: handle signals more transparentlyPádraig Brady
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.
2012-05-04maint: rely on gnulib's new sys_resource moduleJim Meyering
* 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.
2012-01-27maint: use single copyright year rangeJim Meyering
Run "make update-copyright".
2012-01-22maint: quote 'like this' or "like this", not `like this'Paul Eggert
* doc/coreutils.texi (Formatting the file names): coreutils now quotes 'like this'. * man/help2man: * src/timeout.c (usage): Quote 'like this' in diagnostics. * HACKING, Makefile.am, NEWS, README, README-hacking, TODO, cfg.mk: * doc/Makefile.am, doc/coreutils.texi, m4/jm-macros.m4: * man/Makefile.am, man/help2man, src/Makefile.am, src/copy.h: * src/extract-magic, src/ls.c, src/pinky.c, src/pr.c, src/sort.c: * src/split.c, src/timeout.c, src/who.c, tests/dd/skip-seek-past-file: * tests/pr/pr-tests: Quote 'like this' in commentary. * cfg.mk (old_NEWS_hash): Update due to changed old NEWS.
2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2011-10-03build: don't use automake's obsolete AM_C_PROTOTYPES macroJim Meyering
* m4/jm-macros.m4 (gl_CHECK_ALL_TYPES): Remove use of AM_C_PROTOTYPES, now that automake rejects it.
2011-10-01maint: clean up m4 syntaxJim Meyering
* m4/jm-macros.m4 (coreutils_MACROS, gl_CHECK_ALL_HEADERS): Remove unnecessary backslashes and add quotes around multi-line argument lists.
2011-10-01build: use getgr*_nomembers functions on InterixMarkus Duft
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.
2011-07-22dd, shred: use fdatasync only if declaredPaul Eggert
* 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)
2011-07-20maint: remove a redundant call to gl_CLOCK_TIMEPádraig Brady
* m4/jm-macros.m4: Remove gl_CLOCK_TIME as it's already done by the gettime gnulib module.
2011-07-08timeout: handle signals more transparentlyPádraig Brady
* 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.
2011-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2010-09-18build: use gnulib's new termios moduleJim Meyering
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.
2010-07-22fadvise: new module providing a simpler interface to posix_fadvisePádraig Brady
* 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.
2010-04-29build: remove now-duplicate use of AC_SYS_LARGEFILEJim Meyering
* m4/jm-macros.m4 (gl_CHECK_ALL_TYPES): Don't require AC_SYS_LARGEFILE, now that gnulib does it.
2010-04-29build: remove now-useless configure-time header checksJim Meyering
* m4/jm-macros.m4 (gl_CHECK_ALL_HEADERS): Don't test for headers that gnulib now provides: sys/ioctl.h, sys/time.h, sys/wait.h.
2010-04-06maint: fix a masked syntax-check violationJim Meyering
* 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.
2010-03-04sort: inform the system about our input access patternJoey Degges
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.
2010-01-25who --mesg (-T) can use a more accurate test for TTY writabilityKamil Dudka
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.
2010-01-01maint: update all FSF copyright year lists to include 2010Jim Meyering
Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright
2009-10-20maint: issue warnings for more missing optional librariesPádraig Brady
* 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.
2009-10-15build: don't let environment settings perturb buildJim Meyering
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.
2009-10-10copy: allow symlink timestamp preservation on more systemsEric Blake
* 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.
2009-09-11rm: use gnulib faccessatEric Blake
* 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.
2009-09-11rm: improve efficiency of rm -r (without -f) from O(N^2) to O(N)Jim Meyering
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.
2009-09-04build: fix libcap configure flag handlingMike Frysinger
* 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 $enableval at all. This change makes sure we do the sane thing: --disable-libcap -> disable and don't run any tests --enable-libcap -> run tests and fail if not found default -> run tests and warn if not found
2009-08-25global: convert indentation-TABs to spacesJim Meyering
Transformed via this shell code: t=$'\t' git ls-files \ | grep -vE '(^|/)((GNU)?[Mm]akefile|ChangeLog)|\.(am|mk)$' \ | grep -vE 'tests/pr/|help2man' \ | xargs grep -lE "^ *$t" \ | xargs perl -MText::Tabs -ni -le \ '$m=/^( *\t[ \t]*)(.*)/; print $m ? expand($1) . $2 : $_'
2009-08-04cp -pP (and e.g., -a): preserve time stamps on symlinks, tooJim Meyering
* 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
2009-08-04install runs faster again with SELinux enabledKamil Dudka
* 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".
2009-06-15tail: use inotify if it is availableGiuseppe Scrivano
* 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.
2009-01-21m4: don't use AC_REQUIRE([AC_C_BIGENDIAN])Jim Meyering
* 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
2009-01-01improve M4 quotingJim Meyering
* 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.
2009-01-01maint: tighten m4 AC_ quoting checkJim Meyering
* 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.
2008-11-30m4: avoid a warning from gcc's -Wstrict-prototypesJim Meyering
* m4/jm-macros.m4 (ARGMATCH_DIE_DECL): Use proper prototype for usage.
2008-11-11jm-macros.m4: avoid syntax issue with newer autoconfEric Blake
* jm-macros.m4 (coreutils_MACROS): Make LIB_CAP assignment persistent. Signed-off-by: Eric Blake <ebb9@byu.net>
2008-08-01ls: --color now highlights files with capabilities, tooKamil Dudka
* 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.
2008-06-15address root cause of compilation failures:Jim Meyering
The affected code wasn't even being compiled on my system, because HAVE_NL_LANGINFO was not defined. On other systems, where vasnprintf.m4 determines it needs %A or %a replacement support, it _would_ check for nl_langinfo, and expose the compilation failure. * m4/jm-macros.m4: Check for nl_langinfo, required by sort.c.
