2010-06-14cat: improve documentationEric Blake
* src/cat.c (usage): Clarify that -b overrides -n. * doc/coreutils.texi (cat invocation): Likewise. * THANKS: Update. Suggested by Chas. Owens, in bug 6383.
2010-06-08dirname: tweak summary wordingEric Blake
* doc/coreutils.texi (dirname invocation): Reword to be more precise. * src/dirname.c (usage): Likewise. * THANKS: Update. Reported by Filipus Klutiero, bug 6175.
2010-06-02touch: remove support for --file=REF_FILE optionJim Meyering
* src/touch.c (main): Remove support for the deprecated, long-named --file option, which is an alternate name for --reference (-r). That option was undocumented with the arrival of --reference, in the 1995-10-29 commit, 8b92864e1d. Since the 2009-02-09 commit, ed85df444a, use of --file has elicited a warning. Not only was this code due for removal, but the long-name-use-detecting code was buggy in that it would use a stale or uninitialized "long_idx", as reported by Robin H. Johnson in http://bugs.gentoo.org/322421. * NEWS (Changes in behavior): Mention it.
2010-04-22base64: always treat input in binary modeEric Blake
Necessary for cygwin. Technically, this patch is not correct, in that it clobbers O_APPEND, but it is no different than any other use of xfreopen to force binary mode, so all such uses should be fixed at once in a later patch. * src/base64.c (main): Open input in binary mode. * THANKS: Update. Reported by Yutaka Amanai.
2010-04-20sort: fix parsing of end field in obsolescent key formatsPádraig Brady
This regression was introduced in commit 224a69b5, 2009-02-24, "sort: Fix two bugs with determining the end of field". The specific regression being that we include 1 field too many when an end field is specified using obsolescent key syntax (+POS -POS). * src/sort.c (struct keyfield): Clarify the description of the eword member, as suggested by Alan Curry. (main): When processing obsolescent format key specifications, normalize eword to a zero based count when no specific end char is given for an end field. This matches what's done when keys are specified with -k. * tests/misc/sort: Add a few more tests for the obsolescent key formats, with test 07i being the particular failure addressed by this change. * THANKS: Add Alan Curry who precisely identified the issue. * NEWS: Mention the fix. Reported by Santiago Rodríguez
2010-03-26timeout: use more standard option parsingKim Hansen
* src/timeout.c (main): Don't use parse_long_options() which is a helper for commands that don't have any long options specific to them. * tests/misc/timeout-parameters: Remove a case that now passes due to us accepting multiple instances of the --help and --version options. * THANKS: Add the author. Signed-off-by: Pádraig Brady <P@draigBrady.com>
2010-03-18doc: improve ls --help's description of --escape (-b)Eric Blake
* src/ls.c (usage): Be more precise about how --escape (-b) works: say "C-style escapes", not "octal escapes". Reported by Jacky Fong.
2010-02-15dirname: improve man page descriptionEric Blake
* doc/coreutils.texi (dirname invocation): Properly cover behavior on directory. * man/dirname.x: Likewise. * THANKS: Update. Reported by Emmanuel Lacour.
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.
2010-01-07maint: change an email address in THANKSJim Meyering
* THANKS: Adjust Denis' address.
2010-01-06pr: ensure the page header line is of the required formatEric Blake
Before this change, with too long a file name, the name would abut the date field on the left and possibly also the "Page N" field on the right, rather than leaving a one-space separator in each case. Fixes a regression introduced on Mar 6 2009, by commit a4053c5291d5797734b3e4f042f9e1adf3944fd6 * src/pr.c (print_header): Ensure that there is at least one space before and after the file name part of the header line. * NEWS: Mention it. * tests/pr/W20l24f-ll: s/xPage/ x Page/. * THANKS: Update. Reported by Denis McKeon, in https://savannah.gnu.org/bugs/?28492.
2010-01-01ls: fix color of broken symlinks colored as targetEric Blake
* src/ls.c (print_color_indicator): When using 'LINK target' in dircolors, treat broken symlink as C_ORPHAN. * tests/misc/ls-misc (sl-dangle2, sl-dangle3, sl-dangle4) (sl-dangle5): Test for it, and add more coverage. * NEWS: Document it. * THANKS: Update. Reported by Chris Jones.
2009-12-31doc: update tail's documentation to allow for new -F semanticsJim Meyering
* src/tail.c (usage): Reword tail -F description, so that it no longer mentions details specific to the non-inotify implementation. Also, join diagnostic strings (while staying under the 509-byte limit) to ease formatting of translations. The latter was prompted by a report from Stéphane Raimbault. * doc/coreutils.texi (tail invocation): Update description here, too.
2009-12-30touch: work around ntfs-3g bugEric Blake
* gnulib: Update, for utimensat fix. * NEWS: Improve wording about touch fixes. * THANKS: Update. Reported by Stuart Citrin.
2009-12-29tail: add a test to exercise abort-inducing flaw in tail -FJim Meyering
* tests/tail-2/inotify-hash-abuse: New file, derived from a report by Rob Wortman. * tests/Makefile.am (TESTS): Add it. Improved by: Pádraig Brady.
2009-12-26tac: supply link dependencyEric Blake
* src/Makefile.am (tac_LDADD): Add LIB_GETHRXTIME. * THANKS: Update. Reported by Robert Schwebel.
2009-12-19touch: fix ctime regression in 'touch -a'Eric Blake
Regression introduced in coreutils 8.1 due to a bug in the Linux kernel implementation of utimensat with mtime of UTIME_OMIT. * gnulib: Update to latest, to pick up utimensat fix. * NEWS: Mention the change. * THANKS: Update. Reported by John Stanley.
2009-12-12tests: tail-without-inotify: avoid spurious test failureJim Meyering
* tests/tail-2/wait: Account for the possibility that the kernel lacks inotify support. Reported by Chris Clayton.
2009-12-04id: handle systems without getgroups supportEric Blake
If getgroups failed with ENOSYS, mgetgroups would unnecessarily fail, and that provoked id into freeing an uninitialized pointer. Meanwhile, we were not using xalloc_die properly. Both issues are better solved in gnulib, by introducing xgetgroups; this patch uses the new interface. Regression introduced by commit 6a31fd8d7. * gnulib: Update, for mgetgroups improvments. * src/id.c (print_full_info): Adjust caller to die on allocation failure, and no longer worry about ENOSYS. * src/group-list.c (print_group_list): Likewise. * src/setuidgid.c (main): Likewise. * NEWS: Mention the fix. * THANKS: Update. Reported by Scott Harrison.
2009-12-01rm: fix empty-name bug introduced with conversion to use ftsJim Meyering
While "rm ''" would properly fail, "rm F1 '' F2" would fail to remove F1 and F2, due to the empty string argument. This bug was introduced on 2009-07-12, via commit 4f73ecaf, "rm: rewrite to use fts". * gnulib: Update to latest, for fixed fts.c. * NEWS (Bug fixes): Describe it. * tests/rm/empty-name: Adjust for changed diagnostic. (mk_file): Define, copied from misc/ls-misc. (empty-name-2): New test, for today's fix. * lib/xfts.c (xfts_open): Reflect the change in fts_open, now that it no longer fails immediately when one argument is the empty string. Assert that the bit flags were not the cause of failure. * po/POTFILES.in: Remove xfts.c. * THANKS: Update. Reported by Ladislav Hagara.
2009-11-16tail -F can fail to track a file after it's been rotatedJim Meyering
Tailing forever and by-name (--follow=name, -F), tail would sometimes fail to follow a file that had been removed via rename. If you can't apply this patch and have tail 7.6 or newer, you can work around the bug via the undocumented --disable-inotify option. * src/tail.c (tail_forever_inotify): When tailing by name (-F), do not un-watch a file upon receipt of the IN_MOVE_SELF event. Reported by Arjan Opmeer in http://bugs.debian.org/548439. * NEWS (Bug fixes): Mention it. Also see http://marc.info/?l=coreutils-bug&m=125829031916515 * tests/Makefile.am (TESTS): Add tail-2/inotify-rotate. * tests/tail-2/inotify-rotate: New test.
2009-11-13build: correct gettext configure-time supportJim Meyering
* configure.ac: Use AM_GNU_GETTEXT([external], [need-ngettext]), rather than AM_GNU_GETTEXT([external], [need-formatstring-macros]). Reported by Martin Jacobs in http://thread.gmane.org/gmane.comp.parsers.bison.bugs/3181 * THANKS: Add his name.
2009-11-09ls: fix capability coloringPádraig Brady
Capability checking was incorrectly done on just the base name rather than on the whole path. Consequently there could be both false positives and negatives when coloring files with capabilities. Also capability checking was not done at all in certain cases for non executable files. Note passing absolute rather than relative names to cap_get_file() reduces the has_capability() overhead from around 33% to 30%. I.E. ls --color is now around 3% faster. * src/ls.c (struct fileinfo): Add a has_capability member. (print_color_indicator): Refactor to pass just a fileinfo pointer and a flag to say if we're dealing with a symlink target. (print_name_with_quoting): Likewise. (gobble_file): Set has_capability in the fileinfo struct. Also do a capability check even if executable coloring is disabled. Ditto for SETUID and SETUID coloring. Comment on how expensive has_capability() is. (print_long_format): Adjust to refactored print_name_with_quoting. (quote_name): Likewise. (print_file_name_and_frills): Likewise. * tests/ls/capability: Test the various false positive and negatives. * THANKS: Add reporter (Ivan Labath). * NEWS: Mention the fix.
2009-11-03rm -f: ignore EROFS when it's really ENOENTJim Meyering
rm -f must not print a diagnostic for a nonexistent file. However, most linux-based kernel unlinkat functions set errno to EROFS when the named file (regardless of whether it exists) would lie on a read-only file system. remove.c now performs an extra fstatat call in that case, to determine whether the file exists. * src/remove.c (excise): Map EROFS to ENOENT, if a file is nonexistent. Reported by Steven Drake in <http://savannah.gnu.org/bugs/?27923>. * NEWS (Changes in behavior): Mention it.
2009-10-26tests: rm/one-file-system: work around umount failureJim Meyering
* tests/rm/one-file-system (cleanup_): Unmount a/b, rather than "$other_partition_tmpdir", to accommodate those who link /etc/mtab to /proc/mounts. Reported by Gilles Espinasse in http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/18508
2009-10-12tail: tweak usage for more clarityEric Blake
* src/tail.c (usage): Spell out -n +K. * THANKS: Update. Reported by Jan-Pawel Wrozstinski.
2009-10-06chcon: exit immediately if SELinux is disabledOndřej Vašík
This change happens to avoid an abort in chcon when SELinux is disabled while operating on a file with an "unlabeled" context from back in 2006. However, that same abort can still be triggered by the same file when running chcon with SELinux enabled. This bug in chcon will be fixed in a subsequent commit via a getfilecon wrapper. See http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/18378/focus=18384 for how to correct your disk attributes to avoid triggering this bug. * src/chcon.c (main): Exit immediately if SELinux is disabled. Reported in http://bugzilla.redhat.com/527142 by Yanko Kaneti. * src/runcon.c (main): Do not hardcode program name in error message. * THANKS: Update.
2009-10-02dircolors: highlight .cgm and .emf as imagesJames R. Van Zandt
* src/dircolors.hin: Add .cgm, .emf. * THANKS: Update.
2009-09-29ls: with -LR, exit with status 2 upon detecting a cycleJim Meyering
* src/ls.c (print_dir): Diagnosing the cycle is not enough. Also set exit status to 2. This is what Solaris' /bin/ls does, too. * tests/ls/infloop: Rework test: match both expected stdout and stderr. Require an exit status of 2 in this case. * doc/coreutils.texi (ls invocation): Mention that a loop provokes in an exit status of 2. * NEWS (Bug fixes): Mention it. Reported by Yang Ren in http://bugzilla.redhat.com/525402. * THANKS: Correct ordering of Yang Ren's names.
2009-09-21doc: normalize and add missing entries to texinfo menuPádraig Brady
* doc/coreutils.texi: Add the missing arch, base64, link, readlink, and unlink entries. Also remove extraneous '.' from some entries and try to align all entries on the same column. * THANKS: Add Benno Schulenberg.
2009-09-19dircolors: arrange to highlight names with the .lz suffixJim Meyering
* src/dircolors.hin: Add .lz, for GNU lzip. Suggested by Matias A. Fonzo.
2009-09-19mktemp: adapt to new, 3-argument gen_tempname_lenJim Meyering
* src/mktemp.c (mkstemp_len, mkdtemp_len): Update callers of gen_tempname_len. * gl/lib/tempname.c, gl/lib/tempname.h: Rebase against recently API-modified copy of tempname module in gnulib. Reported by Lluís Batlle.
2009-09-07tail: ignore -f for piped-stdin, as POSIX requiresJim Meyering
* src/tail.c (main): Tailing a pipe "forever" is not useful, and POSIX specifies that tail ignore the -f when there is no file argument and stdin is a FIFO or pipe. So we do that. In addition, GNU tail excludes "-" arguments from the list of files to tail forever, when the associated file descriptor is connected to a FIFO or pipe. Before this change, ":|tail -f" would hang. Reported by Ren Yang and Ulrich Drepper. * tests/tail-2/pipe-f: Test for this. * tests/tail-2/pipe-f2: Ensure tail doesn't exit early for a fifo. * tests/Makefile.am (TESTS): Add these tests. * NEWS (POSIX conformance): Mention it.
2009-09-07tail -f: handle "-"/stdin once againJim Meyering
* src/tail.c (main) [HAVE_INOTIFY]: When stdin (i.e., "-", or no args, but not /dev/stdin) is specified on the command line, don't use inotify. Reported by Bill Brelsford in <http://bugs.debian.org/545422>. * tests/tail-2/follow-stdin: New file. Test for this. * tests/Makefile.am (TESTS): Add the test. * NEWS (Bug fixes): Mention it. This bug was introduced in coreutils-7.5 via commit ae494d4b, 2009-06-02, "tail: use inotify if it is available".
2009-09-06tests: ls-misc: don't let a bogus umask cause test failureJim Meyering
* tests/misc/ls-misc: Set umask to 022. A umask setting permitting world-write access, e.g., umask o+w, would cause this test to fail. Report by Mathias Brodala and analysis by Tom Fitzhenry in <http://bugs.debian.org/544965>.
2009-09-03df: don't fail due to an unreadable argumentJim Meyering
* src/df.c (main): If open or fstat fails when we're trying to ensure that all arg-partitions are automounted, fall back on using stat. Inspired by the report and patch from Olivier Fourdan in http://bugzilla.redhat.com/520630. * NEWS (Bug fixes): Mention it. * tests/df/unreadable: New test for the above. * tests/Makefile.am (TESTS): Add df/unreadable. The bug was introduced in coreutils-7.3 via commit dbd17157, 2009-04-28, "df: use open(2), not stat, to trigger automounting".
2009-09-03doc: install -C: fix bug in the texi documentationKamil Dudka
* doc/coreutils.texi: Move the documentation for install --compare (-C) from the section on fmt to that for install. Reported by Florian Schlichting.
2009-08-13dd: fix a signal handling racePádraig Brady
* src/dd.c (main): Install the signal handlers at startup rather than just before the copy starts. In this way signals received before the copy (like during a slow truncate for e.g.) will be deferred and handled consistently. * THANKS: Add Bernhard's email address. * NEWS: Mention the fix. Reported by Bernhard Voelker.
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.
2009-07-27ls -1U dir arg ... now works againKamil Dudka
* src/ls.c (print_dir): Emit "$dir_name:\n" *before* accumulating (and possibly printing) directory entry names. The bug was introduced in coreutils-7.0 via commit 8d974b00, 2008-07-30, "ls -U1 now uses constant memory". Reported by Julian Bradfield. * NEWS (Bug fixes): Mention it.
2009-06-13sort: Ignore fields where end position is before the start positionCliff Miller
* NEWS: Mention the fix * THANKS: Add Cliff Miller * src/sort.c (keycompare): Ensure lima >= texta * tests/misc/sort: Add 3 corresponding tests Signed-off-by: Pádraig Brady <P@draigBrady.com>
2009-05-26sort: new --human-numeric-sort option to sort KiB MB etc.Michael Speer
* NEWS: Document the new option * doc/coreutils.texi (sort invocation): ditto * src/sort.c (main): handle the new --human-numeric-sort option (-h). (human_numcompare): A new function to compare SI and IEC suffixes before falling back to the standard --numeric comparison. (find_unit_order): A new helper function to find the order of magnitude of a number string as determined by its suffix. (check_mixed_SI_IEC): A new helper function to exit with error if both SI and IEC suffixes are presented. * tests/misc/sort: Add 8 tests to test the new functionality. * THANKS: Update
2009-04-28df: use open(2), not stat, to trigger automountingTomas Smetana
* src/df.c (main): When iterating over command-line arguments, attempting to ensure each backing file system is mounted, use open, not stat. stat is no longer sufficient to trigger automounting, in some cases. Based on a suggestion from Ian Kent. More details in http://bugzilla.redhat.com/497830
2009-04-23sort -m: don't segfault when output file is also an input fileJim Meyering
* src/sort.c (avoid_trashing_input): Fix an off-by-one error and guard the use of memmove. * NEWS (Bug fixes): Mention it. * tests/misc/sort: Add tests to exercise the offending code. * THANKS: Update. Reported by Otavio Salvador in http://bugs.debian.org/525048.
2009-04-09id: fix infinite loop on some systemsPádraig Brady
Steven Parkes reported that `id -G $USER` went into an infinite loop on Darwin systems for users in more than 10 groups: http://bugs.gentoo.org/show_bug.cgi?id=264007 * gl/lib/mgetgroups.c (mgetgroups): Work around buggy getgrouplist implementations that don't update the required size correctly, by doubling the result buffer and retrying. Also return the parameter updated by getgrouplist rather than its return value, as the documentation doesn't actually state the number of groups stored is returned by getgrouplist. * tests/misc/id-groups: Add test to exercise this logic * tests/Makefile.am: Reference new test * NEWS: Mention the fix * THANKS: Update
2009-04-07shred,sort,shuf: don't use /dev/urandom by defaultPádraig Brady
Suggestion from Steven Schveighoffer at: http://savannah.gnu.org/patch/?6797 to greatly speed up the random passes done by shred. * gl/lib/randread.c: Default to using the internal pseudorandom generator, rather than reading /dev/urandom * src/shred.c (usage): remove mention of /dev/urandom * src/shuf.c (usage); ditto * src/sort.c (usage): ditto * doc/coreutils.text: Document the new behaviour for aquiring random data.
2009-04-02tests: skip mv/i-3 if /dev/stdin is unreadableJim Meyering
* tests/mv/i-3: Skip if /dev/stdin is unreadable. Reported by Sergei Steshenko.
2009-03-25pwd: support -L and -PEric Blake
* src/pwd.c (longopts): New variable. (logical_getcwd): New function. (main): Use it. (usage): Document new options. * doc/coreutils.texi (pwd invocation): Likewise. * NEWS: Likewise. * TODO (pwd): Mark it done. * tests/misc/pwd-option: New file. * tests/Makefile.am (TESTS): Add test. * THANKS: Update. Reported by Paul D. Smith, in savannah bug 24949.
2009-03-18tests: add another sort/nmerge testPaul Eggert
* tests/Makefile.am (TESTS): Add sort-merge-fdlimit. * tests/misc/sort-merge-fdlimit: New file. * doc/coreutils.texi (sort invocation): Document that we now silently lower nmerge if necessary. Patch by Paul Eggert, Nima Nikzad, Max Chang, Alexander Nguyen, Sahil Amoli, and Nick Graham.
