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".
2011-10-09rm: do not resort to stat'ing very long names even on deficient systemsJim Meyering
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
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.
2011-09-08stat: avoid compilation failure on AIX 7.xJim Meyering
* 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
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".
2010-12-28coreutils: keep lines within 80-column limitsPaul Eggert
* cfg.mk (LINE_LEN_MAX, FILTER_LONG_LINES): New macros. (sc_long_lines): New rule. * HACKING: Use shorter URLs to the same material. * doc/Makefile.am, doc/coreutils.texi, m4/boottime.m4: * man/help2man, man/stdbuf.x, src/Makefile.am, src/cat.c, src/copy.c: * src/cp.c, src/dd.c, src/df.c, src/du.c, src/groups.c, src/install.c: * src/ls.c, src/md5sum.c, src/mv.c, src/od.c, src/pinky.c, src/ptx.c: * src/readlink.c, src/remove.c, src/rmdir.c, src/setuidgid.c: * src/sort.c, src/tail.c, src/touch.c, tests/Coreutils.pm: * tests/cp/existing-perm-race, tests/cp/perm, tests/cp/preserve-gid: * tests/du/2g, tests/du/long-from-unreadable, tests/init.sh: * tests/install/basic-1, tests/ls/nameless-uid: * tests/ls/readdir-mountpoint-inode, tests/misc/chroot-credentials: * tests/misc/cut, tests/misc/date, tests/misc/join, tests/misc/md5sum: * tests/misc/sha1sum, tests/misc/sha224sum, tests/misc/sort: * tests/misc/sort-continue, tests/misc/sort-files0-from: * tests/misc/sort-rand, tests/misc/stdbuf, tests/misc/tr: * tests/misc/uniq, tests/mv/atomic, tests/mv/part-fail: * tests/mv/part-symlink, tests/mv/sticky-to-xpart, tests/pr/pr-tests: * tests/rm/fail-2eperm, tests/rm/interactive-always: Reformat to fit within 80 columns. * doc/Makefile.am (BAD_POSIX_PERL): New macro. * doc/coreutils.texi: Reword slightly, to make menus and index lines shorter. * src/md5sum.c: Redo --help output so that it fits within 79 columns, since that's a bit more portable and all the other --help strings fit in 79 columns.
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.
2010-08-04sort: -R now uses less memory on long lines with internal NULsPaul Eggert
* 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.
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.
2010-01-19build: fix failure from bogus USE_XATTR definitionEric Blake
* m4/xattr.m4 (gl_FUNC_ADDR): Fix regression introduced in commit 6beca4248. * THANKS: Update. Reported by Adam Sampson.
2010-01-12build: fix build failure due to missing libxattrJim Meyering
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.
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.
2009-10-19build: use gnulib's isblank moduleJim Meyering
* bootstrap.conf (gnulib_modules): Add isblank. * src/system.h (isblank): Don't define. * m4/check-decl.m4: Don't check for isblank declaration. * gnulib: Update submodule to latest.
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.
2009-10-08maint: remove unused macros and declarationsEric Blake
* src/system.h (EDQUOT, EISDIR, ENOSYS, EOVERFLOW, F_OK, X_OK) (W_OK, R_OK): Delete; macros provided by gnulib. (includes): Gnulib guarantees both <time.h> and <sys/time.h>, in either order. (free, malloc, memchr, realloc, getenv, lseek): Delete, gnulib guarantees these declarations. * m4/check-decl.m4 (gl_CHECK_DECLS): Delete checks now done by gnulib.
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".
2009-08-04maint: move the update-copyright rule to gnulib's maint.mkJim Meyering
* 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.
2009-07-29maint: make update-copyright work in yet another caseJim Meyering
* 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.
2009-06-23maint: update all Copyright year lists to include 2009Jim Meyering

* 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.
2009-04-30stdopen: remove unused codeEric Blake
* m4/stdopen.m4: Delete now-unused file. * lib/stdopen.h: Likewise. * lib/stdopen.c: Likewise.
2009-04-04maint: clean up Makefile.am, rename remaining ChangeLog filesJim Meyering
* Makefile.am (changelog_etc, syntax_check_exceptions): Define. (EXTRA_DIST): Use. Remove names that are now automatically included: build-aux/git-version-gen, build-aux/vc-list-files. * build-aux/ChangeLog-2007: Rename from */ChangeLog. * doc/ChangeLog-2007: Likewise. * lib/ChangeLog-2007: Likewise. * m4/ChangeLog-2007: Likewise. * po/ChangeLog-2007: Likewise.

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
