* 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>
2009-06-11tests: ls --color, permissions override hardlink coloringPádraig Brady
* tests/ls/multihardlink: Add a test case to demonstrate and test this non obvious behavior.
2009-06-11ls --color: do not colorize files with multiple hard links by defaultKamil Dudka
* src/ls.c: Rename hl->mh, do not colorize files with multiple hard links by default. * src/dircolors.c: Rename HARDLINK -> MULTIHARDLINK, hl -> mh. * src/dircolors.hin: Do not colorize files with multiple hard links by default. * tests/Makefile.am: Rename the test case accordingly. * tests/ls/multihardlink: Additionally test ls' default behavior and factor out some duplication. * NEWS: Mention the change in behavior.
2009-06-02chroot: make --groups= work without --userspec=; be more robustJim Meyering
* src/chroot.c (set_additional_groups): Add comments. Given an empty or all-comma group list, diagnose it and return nonzero. When more than one group is invalid, diagnose all of them, not just the first. (main): Honor --groups= also when --userspec= is not specified. Now that set_additional_groups consistently diagnoses its failures, don't diagnose it separately here. * tests/chroot/credentials: Do not invoke with an empty group list.
2009-06-02chroot: don't set bogus user-ID or group-ID for --u=U: or --u=:GJim Meyering
* src/chroot.c (main): Initialize both "uid" and "gid". To -1. This also allows one to set the user-ID or primary group-ID to 0, in case it's not that already. * tests/chroot/credentials: Test for the above.
2009-06-02tests: use "nobody" as the default group name in chroot testJim Meyering
* tests/test-lib.sh (NON_ROOT_GROUP): Use "nobody", not "nogroup".
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
2009-05-26chroot: accept new options --userspec=U:G and --groups=G1,G2,G3Giuseppe Scrivano
* NEWS: Note chroot's new options. * doc/coreutils.texi: Document them. * src/chroot.c (main): Add support for --userspec and --groups. * tests/Makefile.am (root-tests): Add chroot/credentials. * tests/chroot/credentials: New file. * tests/test-lib.sh: Define NON_ROOT_GROUP to a default value.
2009-05-15tests: fix date-next-dow failure on older systemsPádraig Brady
* tests/misc/date-next-dow: In the strftime call use %Y-%m-%d rather than the newer %F equivalent which is not available on Solaris 8 for example.
2009-05-05tests: rm/one-file-system: umount more reliablyJim Meyering
* tests/rm/one-file-system: Run umount via trap, so it runs also upon irregular termination.
2009-05-03tests: add tests of e.g., date -d 'next monday'Jim Meyering
* tests/misc/date-next-dow: New file. * tests/Makefile.am (TESTS): Add misc/date-next-dow. * gnulib: Update submodule to latest, for getdate.y that handles "next Monday" properly when run on a Monday.
2009-04-28tests: ensure that cp's -a doesn't silence --preserve=contextOndřej Vašík
* tests/cp/cp-a-selinux: Ensure that the -a option does not silence error diagnostics from --preserve=context, when preserving context is required.
2009-04-28tests: add test for xattr diagnostics on dest. FS lacking xattr supportOndřej Vašík
* tests/cp/cp-mv-enotsup-xattr: Ensure that xattr diagnostics are displayed correctly when destination filesystem lacks xattr support. * tests/Makefile.am (root_tests): Add new root-only test.
2009-04-24tests: avoid unusual (~1-in-20) failure of a new testJim Meyering
* tests/misc/sort: Remove one of the generated tests. 363 remain in this file alone.
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.
2009-04-22cp: work around linux kernel bug: short-read != EOF on /procJim Meyering
Remove the optimization that avoided up to 50% of cp's read syscalls. Do not assume that a short read on a regular file indicates EOF. When reading from a file in /proc on linux [at least 2.6.9 - 2.6.29] into a 4k-byte buffer or larger, a short read does not always indicate EOF. For example, "cp /proc/slabinfo /tmp" copies only 4068 of the total 7493 bytes. This optimization (25719a33154f0c62ea9881f0c79ae312dd4cec7a, Improve performance a bit by optimizing away; 2005-11-24) appears to have been worth less than a 2% speed-up (and usually much less), so the impact of removing it is negligible. * src/copy.c (copy_reg): Don't exit the loop early. * tests/cp/proc-short-read: New test, lightly based on a suggestion from Mike Frysinger, to exercise this fix. * tests/Makefile.am (TESTS): Add cp/proc-short-read. * NEWS (Improve robustness): Mention this change.
2009-04-22tests: avoid new "make distcheck" failure due to newer File::TempJim Meyering
With newer perl (e.g., Fedora 10's 4:5.10.0-68.fc10), tests/CuTmpdir.pm stopped removing its temporary directories, with diagnostics like this: cannot remove path when cwd is /c/coreutils/tests/misc/seq.tmp-e2up \ for /c/coreutils/tests/misc/seq.tmp-e2up: at \ /usr/lib/perl5/5.10.0/File/Temp.pm line 902 Chdir out of the target directory before that code runs: * tests/CuTmpdir.pm (END): chdir '..'. (chmod_tree): Remove explicit "chdir $dir".
2009-04-19tests: avoid failure of install-C test on FreeBSD UFS file systemAurelien Jarno
* tests/install/install-C: Use 2755 (set-gid), not 1755 (sticky), to test install -C with non-permission mode bits set. At least on FreeBSD with a UFS file system, a non-root user may not set the sticky bit on a non-directory.
2009-04-09tests: misc/ls-misc: avoid shadowing local decl of $eJim Meyering
* tests/misc/ls-misc (make_j_d): Rename latter $e to $env
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

2009-04-03ls: fix alignment when month names have varying widthsPádraig Brady
Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR locale has recently changed to use the official but variable width abbreviated month names. Other glibc locales also have variable widths. http://sourceware.org/ml/libc-locales/2008-q1/msg00035.html http://sourceware.org/bugzilla/show_bug.cgi?id=9859 * NEWS: Mention the fix * gl/lib/mbsalign.c: A new module to align and truncate a string in a specified number of screen cells, while handling multi-byte characters appropriately. * gl/lib/mbsalign.h: Ditto * gl/modules/mbsalign: Ditto * bootstrap.conf: Reference the new module * src/ls.c (abmon_init): New function, precompute the abbreviated months aligned left in a minimum width column <= 5 screen cells. (align_nstrftime): New function, replace the first %b in the format specification to strftime with the precomputed month string. Note using the cached month strings speeds up `ls -lU` by around 17% on glibc-2.7-2 on linux at least. Also if we implement this function using heap storage rather than automatic storage, and use snprintf instead of strcpy, ls will slow down by 2% and 1% respectively (i.e. a net gain of 14% rather than 17%). * tests/ls/abmon-align: A new test to test ls alignment for various formats and locales * tests/Makefile.am: Reference the new test
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.
2009-03-31tests: enable automake's color-tests and parallel-tests via configure.acJim Meyering
* gnulib-tests/Makefile.am (AUTOMAKE_OPTIONS): Don't define here. * tests/Makefile.am (AUTOMAKE_OPTIONS): Likewise. * configure.ac (AM_INIT_AUTOMAKE): Instead, add color-tests and parallel-tests here.
2009-03-31build: use Automake's new parallel-tests featureRalf Wildenhues
* build-aux/check.mk: Remove, not needed any more. * tests/Makefile.am (AUTOMAKE_OPTIONS): Add parallel-tests and color-tests. * tests/check.mk: Do not include build-aux/check.mk any more. (SUFFIXES, TEST_LOGS): Remove. (TESTS_ENVIRONMENT): Use $$f rather than $$tst in $PERL invocation. * gnulib-tests/Makefile.am: Do not include build-aux/check.mk. (AUTOMAKE_OPTIONS): New macro, add parallel-test and color-tests. (TEST_LOGS): Remove.
2009-03-29tests: don't use lang-default from individual testsJim Meyering
* tests/sample-test: Don't recommend using lang-default here. It is now run for each test automatically, via TESTS_ENVIRONMENT. * tests/dd/reblock: Don't source lang-default here. * tests/misc/truncate-fail-diag: Likewise.
2009-03-29tests: other-fs-tmpdir: remove just-added duplicate /usr/tmpJim Meyering
* tests/other-fs-tmpdir (CANDIDATE_TMP_DIRS): Remove 2nd /usr/tmp.
2009-03-29tests: other-fs-tmpdir: avoid bogus "skipped **********..." diagnosticJim Meyering
* tests/other-fs-tmpdir (CANDIDATE_TMP_DIRS): Add /dev/shm to the list. Don't use a line of asterisks as the first line of the "why skipped" diagnostic, now that that line is printed on 'make check's stderr.
2009-03-27tests: avoid spurious test failure in set-GID build dirJim Meyering
* tests/install/install-C-root: Skip this test if in set-gid directory. Reported by Sven Joachim and C de-Avillez.
2009-03-27tests: migrate setgid-check into test-lib.shJim Meyering
* tests/test-lib.sh (skip_if_setgid_): New function. * tests/setgid-check: Remove file. * tests/Makefile.am (EXTRA_DIST): Remove setgid-check. * tests/chmod/c-option: Use the new function rather than sourcing the separate file. * tests/cp/cp-parents: Likewise. * tests/install/install-C: Likewise. * tests/mkdir/parents: Likewise. * tests/mkdir/perm: Likewise.
2009-03-26tests: mark the rm/ext3-perf test as "very" expensiveJim Meyering
* tests/rm/ext3-perf: Relegate this test to the very_expensive category, since it is failing too often for me, when run in parallel (-j4) with other disk-hammering tests. This test fails when it takes too long, so the fact that it fails under pressure is an inconvenience more than a real problem.
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.

2009-03-20tests: avoid spurious mkdir/selinux test failure on HP-UX 11.23Jim Meyering
* tests/mkdir/selinux: Accept yet another diagnostic. Reported by Matthew Woehlke.
2009-03-19tests: df/total-verify: avoid test failure with older PerlJim Meyering

2009-03-18tests: adjust sort-continue not to fail under valgrindJim Meyering
* tests/misc/sort-continue: Don't run cat inside fd-limited shell. If sort fails to run in an fd-limited shell, skip the test.
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.
2009-03-18sort: handle fd exhaustion better when mergingPaul Eggert
This is an alternative to my 9 March patch labeled "Silently lower nmerge; don't (sometimes incorrectly) range-check" <http://lists.gnu.org/archive/html/bug-coreutils/2009-03/msg00070.html>. It differs by not using 'dup' to probe for extra file descriptors; instead, it simply calls 'open' (and 'pipe') to open files and pipes, until one of these calls fails due to file descriptor exhaustion; it then backs off by 1, does a merge with the files that it has opened, and then retries with the (now-smaller) number of files. This patch requires quite a few more changes to the source code than the earlier patch, but it is in some sense "better" because it doesn't need to call "dup" ahead of time in order to decide whether "open" or "pipe" will fail. Also, it's more robust in the case where "open" or "pipe" fails with errno==EMFILE because some system-wide limit is exhausted. * src/sort.c (create_temp_file): New arg SURVIVE_FD_EXHAUSTION. (stream_open): New function, containing guts of xfopen. (xfopen): Use it. (pipe_fork): Set errno on failure. (maybe_create_temp): New function, containing guts of create_temp. (create_temp): Use it. (open_temp): Distinguish failures due to file descriptor exhaustion from other failures, and on fd exhaustion return a notice to caller rather than dying. Don't test execlp's return value; when it returns, it *always* returns -1. (open_input_files): New function. (mergefps): New arg FPS. It's now the caller's responsibility to open the input and output files. All callers changed. (mergefiles): New function. (avoid_trashing_input, merge): Handle the case where a single merge can't merge as much as we wanted due to file descriptor exhaustion, by merging as much as we can and then retrying. * tests/Makefile.am (TESTS): Add misc/sort-continue. * tests/misc/sort-continue: New file. * THANKS: Add Glen Lenker and Matt Pham who coauthored this patch.
2009-03-15maint: remove long-unused MakefileJim Meyering
* tests/sort-time/Makefile: Remove long-unused file.
2009-03-12tests: groups-version: don't require that id be builtJim Meyering
* tests/misc/groups-version: groups is now independent of id.
2009-03-12tests: skip the groups-dash test when "groups" is not builtJim Meyering
* tests/misc/groups-dash: Skip if groups is not being installed. Suggested by Mike Frysinger. Also fail if groups exits with nonzero status.
2009-03-11cp: make -a option preserve xattrs, but with reduced diagnosticsOndřej Vašík
* copy.c (copy_attr_by_fd): Reduce xattr diagnostics for 'cp -a'. (copy_attr_by_name): Likewise. * cp.c (main): Preserve xattrs with -a option, when possible. * doc/coreutils.texi: Document that xattrs are preserved with cp -a, with no added diagnostics. * NEWS: Mention the change. * tests/misc/xattr: Add tests for 'cp --preserve=all' and 'cp -a'.
