2011-10-05tests: add a test to exercise today's ls-lL-vs-ACL bugJim Meyering
* tests/ls/slink-acl: New file. * tests/Makefile.am (TESTS): Add it. * tests/init.cfg (require_setfacl_): New function. * gnulib: Update to latest, for file-has-acl changes. * NEWS (Bug fixes): Mention it. See http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28538. This ":>k; setfacl -m m::r k; ln -s k s; ls -Log s" should print e.g., -rw-r-----+ 1 0 Oct 5 19:22 s With the ls from coreutils-8.13, it would print this (with "." or nothing in place of the "+"): -rw-r-----. 1 0 Oct 5 19:22 s
2011-09-27sort: avoid a NaN-induced infloopJim Meyering
These commands would fail to terminate: yes -- -nan | head -156903 | sort -g > /dev/null echo nan > F; sort -m -g F F That can happen with any strtold implementation that includes uninitialized data in its return value. The problem arises in the mergefps function when bubble-sorting the two or more lines, each from one of the input streams being merged: compare(a,b) returns 64, yet compare(b,a) also returns a positive value. With a broken comparison function like that, the bubble sort never terminates. Why do the long-double bit strings corresponding to two identical "nan" strings not compare equal? Because some parts of the result are uninitialized and thus depend on the state of the stack. For more details, see http://bugs.gnu.org/9612. * src/sort.c (nan_compare): New function. (general_numcompare): Use it rather than bare memcmp. Reported by Aaron Denney in http://bugs.debian.org/642557. * NEWS (Bug fixes): Mention it. * tests/misc/sort-NaN-infloop: New file. * tests/Makefile.am (TESTS): Add it.
2011-09-16md5sum: handle BSD reversed format checksumsPádraig Brady
* src/md5sum.c (split_3): Detect and handle BSD reversed format checksums. * tests/misc/md5sum-bsd: Add a new test. * tests/Makefile.am: Reference new test. * NEWS: Mention the improvement Suggested by Rimas Kudelis.
2011-09-02tests: remove require-perl script; use function insteadJim Meyering
* tests/require-perl: Remove file. * tests/Makefile.am (EXTRA_DIST): Remove it from this list. * tests/init.cfg (require_perl_): New function. * tests/misc/pwd-long: Use the new function, not the file. * tests/ls/nameless-uid: Likewise. * tests/misc/sum-sysv: Likewise.
2011-08-24maint: rename a testJim Meyering
Lesson: do not include details like "4 million" in a file name. * tests/rm/many-dir-entries-vs-OOM: Renamed from ... * tests/rm/4-million-entry-dir: ...this. * tests/Makefile.am (TESTS): Reflect renaming.
2011-08-19rm, du, chmod, chown, chgrp: use much less memory for large directoriesJim Meyering
For details, see the gnulib commit, http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=47cb657e * tests/rm/4-million-entry-dir: New test. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it. * gnulib: Update to latest to get the required fts fixes.
2011-07-25cp: don't mishandle existing dir dest permissions (Bug#9170)Paul Eggert
* src/copy.c (copy_internal): If we don't create the directory, then we cannot have omitted permissions. Problem and trivial fix reported by Eric Lammerts. * tests/Makefile.am (TESTS): Add cp/existing-perm-dir. * tests/cp/existing-perm-dir: New file.
2011-07-25cp -up: preserve all hard linksJim Meyering
* src/copy.c (copy_internal): With --update (-u), this function would return early once it found that the destination is not older than the source, *without* recording the source-dev/ino--to--dest_name mapping. That mapping is required in order to preserve src hard links in the destination tree, so when using cp with --update and --preserve=links (perhaps via -p or -a), cp could fail to preserve one hard link per inode when at least one of the hard-linked names already exists in the destination tree. Reported by Odd Harry Mannsverk in http://debbugs.gnu.org/8419. * tests/cp/preserve-link: New file. Exercise the flaw/fix. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it.
2011-07-08timeout: add --foreground to support interactive commandsPádraig Brady
Or more accurately, commands not started from the shell prompt, that are interactive, or need to receive Ctrl-C etc. from the terminal. * doc/coreutils.texi (timeout invocation): Document --foreground. * src/timeout.c (main): Set the foreground flag and don't create a separate group. (cleanup): Only send a signal directly to the monitored command when the foreground flag is set. (usage): Describe --foreground. * tests/misc/timeout-group: Add a new test. * tests/Makefile.am: Reference new test. NEWS: Mention the new option. Reported by Shay Shimony Analysis by Alan Curry Fix suggested by Paul Eggert
2011-06-19tests: make test runner a script, not a shell functionStefano Lattarini
This change implements a more correct and idiomatic use of the features of the Automake-provided 'parallel-tests' harness. Moreover, this change is required in order for the testsuite to continue to work with the new testsuite harness that is planned to be introduced in Automake 1.12 (which, as of the writing date, is still under development and in alpha state). * tests/shell-or-perl: New auxiliary script. * tests/Makefile.am (EXTRA_DIST): Distribute it. * tests/check.mk (TESTS_ENVIRONMENT): Remove definition of the `shell_or_perl_' shell function, whose code has been moved in the new script above (with a few improvements and extensions). Do not use it to run the test scripts. (LOG_COMPILER): New, properly invoking `shell-or-perl'.
2011-05-28tests: move tests/misc/split-* into tests/split/...Jim Meyering
* tests/split/suffix-length: Rename from tests/misc/split-a. * tests/split/b-chunk: Rename from misc/split-bchunk. * tests/split/fail: Rename from tests/misc/split-fail. * tests/split/lines: Rename from tests/misc/split-l. * tests/split/l-chunk: Rename from tests/misc/split-lchunk. * tests/split/r-chunk: Rename from tests/misc/split-rchunk. * tests/Makefile.am (TESTS): Reflect renaming.
2011-05-13ls: allow stat-free use of --colorJim Meyering
Even on a system with d_type support, the default use of --color makes ls stat every file in order to be able to honor settings like EXEC, STICKY, ORPHAN, SETUID, etc., because those settings require information that is not provided by dirent.d_type. However, if for a potentially large performance gain, you are willing to disable those settings, you can now make ls --color give type-related coloring and perform no stat calls at all (other than the unavoidable call-per- command-line argument). Before this change, even with all of those attributes disabled, ls --color would still stat every directory. Now, we're down to the minimum of one stat call per command-line arg. * src/ls.c (gobble_file): With --color, don't stat a non-command-line-specified directory when no directory-coloring attribute is enabled. * tests/init.cfg (require_dirent_d_type_): New function. * tests/d_type-check: New script, mostly from Pádraig Brady. * tests/Makefile.am (EXTRA_DIST): Add it. * tests/ls/stat-free-color: New test. * tests/Makefile.am (TESTS): Add it. * doc/coreutils.texi (General output formatting): Describe how to use dircolors to make ls --color refrain from calling stat on a d_type-enabled file system. Prompted by a query from Josef Bacik.
2011-05-06tests: test split's new --filter=CMD optionJim Meyering
* tests/Makefile.am (TESTS): Add split/filter. * tests/split/filter: New file.
2011-04-29tests: distribute new file, CuSkip.pmJim Meyering
Without this, most perl-based tests would fail in "make distcheck". * tests/Makefile.am (EXTRA_DIST): Add CuSkip.pm
2011-04-28tests: remove useless test: misc/pwd-unreadable-parentJim Meyering
* tests/Makefile.am (TESTS): Remove misc/pwd-unreadable-parent. This test was misleading and useless (was always skipped). Inspired by a report from Bruno Haible: http://debbugs.gnu.org/8570 * tests/misc/pwd-unreadable-parent: Remove file.
2011-04-25tail --follow=name no longer implies --retryJim Meyering
* src/tail.c (tail_forever_inotify): Just as without inotify, tail --follow=name now terminates when the last tailed-by-name file is unlinked or moved aside. This bug was introduced on 2009-06-15 via commit ae494d4b, "tail: use inotify if it is available". Reported by Tim Underwood in http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/22286 * NEWS (Bug fixes): Mention this. * tests/tail-2/follow-name: Test for this. * tests/Makefile.am (TESTS): Add it.
2011-04-01copy: process empty extents more efficientlyPádraig Brady
* src/copy.c (extent_copy): Treat an allocated but empty extent much like a hole. I.E. don't read data we know is going to be NUL. Also we convert the empty extent to a hole only when SPARSE_ALWAYS so that the source and dest have the same allocation. This will be improved soon, when we use fallocate() to do the allocation. * tests/cp/fiemap-empty: A new test for efficiency and correctness of copying empty extents. * tests/Makefile.am: Reference the new test. * NEWS: Mention the change in behavior.
2011-04-01copy: link rather than copy symlinks, when --link usedPádraig Brady
This bug was introduced in commit ca9e212c, 2009-09-24, "cp, mv: use linkat to guarantee semantics", which inadvertently disabled the creation of hardlinks to symlinks. However rather than implementing the intention of that commit and relying on gnulib linkat emulation, we'll revert to the previous emulation as that maintains ownership and timestamps. * src/copy.c (copy_internal): Use our existing hardlink to symlink emulation when link() might dereference the symlink. Also ensure that we copy the timestamps of the original symlink when we use the emulation. * tests/cp/link-symlink: Add a test to ensure timestamps copied. * tests/Makefile.am: Reference the new test. * NEWS: Mention the fix. Reported by Ruediger Meier
2011-03-05dd: add a flag to discard cached dataPádraig Brady
* src/dd.c (FFS_MASK): A new macro (Find First Set) refactored from the following enum as it's now used twice. (usage): Mention the new 'nocache' flag. (cache_round): A new function to help ignore requests to drop cache, that are less than page_size. (invalidate_cache): A new function to call posix_fadvise() with the appropriate offset and length. Note we don't use fdadvise() so we can detect errors when count=0. (dd_copy): Call invalidate_cache() for the portions read. (iwrite): Likewise for the portions written. (main): Call invalidate_cache for page_size slop or for full file when count=0. * cfg.mk (sc_dd_O_FLAGS): Adjust to pass. * doc/coreutils.texi (dd invocation): Describe the 'nocache' flag, and give some examples of how it can be used. * tests/dd/nocache: A new test. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature.
2011-03-03du: don't infloop for --files0-from=DIRJim Meyering
* src/du.c (main): Fail on AI_ERR_READ error, rather than merely diagnosing and continuing. Based on a patch by Stefan Vargyas. Also move the handling of AI_ERR_EOF into the case stmt. Do not report ferror/fclose(stdin) failure when we've already diagnosed e.g., failure to read the DIR, above. Bug introduced by 2008-11-24 commit 031e2fb5, "du: read and process --files0-from= input a name at a time,". * src/wc.c: Handle read failure as with du: do not exit immediately, but rather go on to print any total and to clean-up. As above, move the handling of AI_ERR_EOF into the case stmt. * tests/du/files0-from-dir: New file, to test both du and wc. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it.
2011-02-19maint: replace spaces with tab in tests/Makefile.amGilles Espinasse
* tests/Makefile.am: Replace spaces with tabs for consistency
2011-02-08test: improve the cp fiemap testsPádraig Brady
* tests/cp/fiemap-2: Enable the fiemap check for files, which will enable the test for files on ext3. * tests/cp/fiemap-perf: Comment why we're not enabling for ext3. * tests/cp/sparse-fiemap: Ditto. Also sync the files before doing a fiemap which was needed for ext4 loop back at least. Add a comment that FIEMAP_FLAG_SYNC is ineffective, thus requiring the explicit syncs. * tests/fiemap-capable: A new python script to determine if a specified path supports fiemap. * tests/init.cfg (fiemap_capable_): Use the new python script. * tests/Makefile.am (EXTRA_DIST): Include the new python script.
2011-01-31tests: exercise a rarely-used corner of copy.cJim Meyering
* tests/cp/sparse-to-pipe: New test. * tests/Makefile.am (TESTS): Add it.
2011-01-30tests: cp/fiemap: exercise previously-failing partsJim Meyering

2011-01-30build: distribute new test script, filefrag-extent-compareJim Meyering
* tests/Makefile.am (EXTRA_DIST): Add filefrag-extent-compare.
2011-01-30tests: add a new test for FIEMAP-copyJie Liu
* tests/cp/sparse-fiemap: Add a new test for FIEMAP-copy against a loopbacked ext4 partition. * tests/Makefile.am (sparse-fiemap): Reference the new test.
2011-01-17tests: add a test for today's uniq bugJim Meyering
* tests/misc/uniq-perf: New file. * tests/Makefile.am (TESTS): Add it.
2011-01-10du: don't abort when a subdir is renamed during traversalJim Meyering
* NEWS (Bug fixes): Mention it. * src/du.c (prev_level): Move declaration "up" to file-scope global. (du_files): Reset prev_level to 0 upon abnormal fts_read termination. Reported by Johathan Nieder in http://bugs.debian.org/609049 Also, improve a diagnostic. * tests/du/move-dir-while-traversing: Test for the above. * tests/Makefile.am (TESTS): Add it.
2010-12-16sort: fix hang with sort --compressPaul Eggert
* NEWS: Document this. * src/sort.c (UNCOMPRESSED, UNREAPED, REAPED): New constants. (struct tempnode): New member 'state', to hold these constants. The pid member is now undefined if state == UNCOMPRESSED. (struct sortfile): Replace member 'pid' with member 'temp'. (uintptr): Remove. (proctab_hasher, proctab_comparator, register_proc, delete_proc): Proctab entries are now struct tempnode *, not pid_t, to handle the case where multiple tempnode objects correspond to the same pid. This avoids a race condition that can cause a hang. (register_proc): Arg is now struct tempnode *, not pid_t. All callers changed. (delete_proc): Set tempnode state to REAPED. (create_temp_file): No need to set pid member here; it's now done when the pid is known. (maybe_create_temp, create_temp): Remove PPID arg. Return struct tempnode *, not char *. All callers changed. (maybe_create_temp): Set node state to UNCOMPRESSED or UNREAPED. No need to set node->pid to 0. (open_temp): Replace NAME and PID args with a single TEMP arg. All callers changed. Wait only for unreaped children. (zaptemp): Wait for decompressor to finish before removing its temporary-file input. This avoids .nfsXXXX hassles with NFS and fixes a race (leading to a hang) regardless of NFS. (open_input_files): Adjust to new way of dealing with temp files and their subprocesses. * tests/Makefile.am (TESTS): Add misc/sort-compress-hang. * tests/misc/sort-compress-hang: New file.
2010-12-13sort: fix some --compress reaper bugsPaul Eggert
* src/sort.c (uintptr): New type. (enum procstate, struct procnode, update_proc): Remove. (proctab_hasher, proctab_comparator, register_proc, wait_proc): (reap_some): The proctab is now simply a hash of process-IDs rather than of pointers to objects with reference counts and states; this is smaller and faster and easier to understand. (nprocs): Now pid_t, not size_t, since one cannot have more than PID_MAX children. (reap): If the argument is -1, wait; if 0 (a new value), do not. Delete pid from proctab as needed. Ignore children that are not in proctab, as they are from the program that exec'ed us and are irrelevant to our success or failure. (delete_proc, reap_all): New functions. (open_temp): Register the child. (sort): Clean up all children afterwards; without this patch, 'sort' sometimes missed failures in children due to race conditions. * tests/Makefile.am (TESTS): Add misc/sort-compress-proc. * tests/misc/sort-compress-proc: New file, to test for the bugs fixed above.
2010-12-12tests: test for access to stale thread memoryPaul Eggert
* tests/misc/sort-stale-thread-mem: New tests. * tests/Makefile.am (TESTS): Add it.
2010-12-11sort: use mutexes, not spinlocks (avoid busy loop on blocked output)Chen Guo
Running a command like this on a multi-core system sort < big-file | less would peg all processors at near 100% utilization. * src/sort.c: (struct merge_node) Change member lock to mutex. All uses changed. * tests/Makefile.am (XFAIL_TESTS): Remove definition, now that this test passes once again. I.e., the sort-spinlock-abuse test no longer fails. * NEWS (Bug reports): Mention this. Reported by DJ Lucas in http://debbugs.gnu.org/7489.
2010-12-01tests: add test for parallel sort -u segfault bugJim Meyering
* tests/misc/sort-unique-segv: New file. * tests/Makefile.am (TESTS): Add it.
2010-11-27tests: test for parallel sort spinlock abuseJim Meyering
* tests/misc/sort-spinlock-abuse: New file. * tests/Makefile.am (TESTS): Add it. (XFAIL_TESTS): Mark this as an expected-to-fail (for now) test.
2010-11-22split: add --number to generate a particular number of filesChen Guo
* src/split.c (usage, long_options, main): New options --number, --unbuffered, --elide-empty-files. (set_suffix_length): New function to auto increase suffix length to handle a specified number of files. (create): New function. Refactored from cwrite() and ofile_open(). (bytes_split): Add max_files argument to support byte chunking. (lines_chunk_split): New function. Split file into chunks of lines. (bytes_chunk_extract): New function. Extract a chunk of file. (of_info): New struct. Used by functions lines_rr and ofile_open to keep track of file descriptors associated with output files. (ofile_open): New function. Shuffle file descriptors when there are more output files than available file descriptors. (lines_rr): New function to distribute lines round-robin to files. (chunk_parse): New function. Parses K/N syntax. * tests/misc/split-bchunk: New test for byte chunking. * tests/misc/split-lchunk: New test for line delimited chunking. * tests/misc/split-rchunk: New test for round-robin chunking. * tests/Makefile.am: Reference new tests. * tests/misc/split-fail: Add failure scenarios for new options. * tests/misc/split-l: Fix a typo. s/ln/split/. * doc/coreutils.texi (split invocation): Document --number. * NEWS: Mention the new feature. * .mailmap: Map new email address for shortlog. Signed-off-by: Pádraig Brady <P@draigBrady.com>
2010-11-18od: fix bugs in displaying floating-point valuesPaul Eggert
* NEWS: Describe patch. * bootstrap.conf (gnulib_modules): Add ftoastr. * src/od.c: Include ftoastr.h, not float.h. (FLT_DIG, DBL_DIG): Remove. No need to verify LDBL_DIG. (FMT_BYTES_ALLOCATED): No need to worry about floating point now, since this format is no longer used for floating point. (PRINT_FIELDS): New macro, with most of the guts of the old PRINT_TYPE. (PRINT_TYPE): Rewrite to use PRINT_FIELDS. (PRINT_FLOATTYPE): New macro. This uses the new functions from ftoastr. (print_float, print_double, print_long_double): Reimplement using PRINT_FLOATTYPE. (decode_one_format): Calculate field widths based on ftoastr-supplied macros. * tests/Makefile.am (TESTS): Add misc/od-float. * tests/misc/od-float: New file.
2010-11-17tests: remove test-lib.sh; now all tests use gnulib's init.shJim Meyering
* tests/test-lib.sh: Remove file. No longer used. * tests/Makefile.am (EXTRA_DIST): Remove it here, too. * tests/sample-test: Correct a comment.
2010-11-11csplit: fix a memory leak per input bufferPádraig Brady
* src/csplit.c (free_buffer): Also free the line offsets buffers (remove_line): Also free the containing structure * tests/misc/csplit-heap: A new test to trigger with leaks of this magnitude. * tests/Makefile.am: Reference the new test * NEWS: Mention the fix Reported by David Hofstee
2010-11-10csplit: avoid buffer overrun when writing more than 999 filesJim Meyering
Without this fix, seq 1000 | csplit - /./ '{*}' would write the NUL-terminated file name, xx1000, into a buffer of size 6. * src/csplit.c (main): Use properly sized file name buffer. * NEWS (Bug fixes): Mention it. * tests/misc/csplit-1000: New test to trigger the bug. * tests/Makefile.am (TESTS): Add misc/csplit-1000.
2010-11-03stat: revert %X-%Y-%Z change; use e.g., %:X to print fractional secondsJim Meyering
This reverts part of the recent commit 9069af45, "stat: print timestamps to full resolution", which made %X, %Y, %Z print floating point numbers. We prefer to retain portability of %X, %Y and %Z uses, while still providing access to full-resolution time stamps via modified format strings. Also make the new %W consistent. * src/stat.c: Include "xstrtol.h". (print_it): Accept a new %...:[XYZ] format directive, e.g., %:X, to print the nanoseconds portion of the corresponding time. For example, %3.3:Y prints the zero-padded, truncated, milliseconds part of the time of last modification. (print_it): Update print_func signature to match. (neg_to_zero): New helper function. (epoch_time): Remove function; replace with... (epoch_sec): New function; use timetostr. (out_ns): New function. Use "09" only when no other modifier is specified. (print_statfs): Change type of "m" to unsigned int, now that it must accommodate values larger than 255. (print_stat): Likewise. Map :X to a code of 'X' + 256. Likewise for Y, Z and W. (usage): Update. * tests/touch/60-seconds: Use %Y.%:Y in place of %Y. * tests/misc/stat-nanoseconds: New file. * tests/Makefile.am (TESTS): Add it. * NEWS (Changes in behavior): Mention this. With improvements by Pádraig Brady. Thanks to Andreas Schwab for raising the issue.
2010-10-23du: don't print junk when diagnosing out-of-range time stampsPaul Eggert
* src/du.c (show_date): Fix call to fputs with a buffer that contains some uninitialized data. * tests/Makefile.am (TESTS): Add du/big-timestamp. * tests/du/bigtime: New file, which checks for the bug.
2010-10-12tail: fix checking of currently unavailable directoriesPádraig Brady
* src/tail.c (tail_forever_inotify): Handle the case where tail --follow=name with inotify, is not able to add a watch on a specified directory. This may happen due to inotify resource limits or if the directory is currently missing or inaccessible. In all these cases, revert to polling which will try to reopen the file later. Note inotify returns ENOSPC when it runs out of resources, and instead we report a particular error message, lest users think one of their file systems is full. (main): Document another caveat with using inotify, where we currently don't recheck directories recreated after the initial watch is setup. * tests/tail-2/F-vs-rename: Fix the endless loop triggered by the above issue. * tests/tail-2/inotify-hash-abuse: Likewise. * tests/tail-2/wait: Don't fail in the resource exhaustion case. * tests/tail-2/F-vs-missing: A new test for this failure mode which was until now just triggered on older buggy linux kernels which returned ENOSPC constantly from inotify_add_watch(). * NEWS: Mention the fix.
2010-10-01stat: support printing birthtimeEric Blake
* src/stat.c (print_stat): New %w and %W formats. (do_stat): Include %w in default format. (usage): Document new specifiers. * doc/coreutils.texi (stat invocation): Likewise. * NEWS: Likewise.
2010-09-29tr: fix various issues with case conversionPádraig Brady
This valid translation spec aborted: LC_ALL=en_US.iso-8859-1 tr '[:upper:]- ' '[:lower:]_' This invalid translation spec aborted: LC_ALL=en_US.iso-8859-1 tr '[:upper:] ' '[:lower:]' This was caused by commit 6efd1046, 05-01-2008, "Avoid tr case-conversion failure in some locales" This misaligned conversion spec was allowed: LC_ALL=C tr 'A-Y[:lower:]' 'a-z[:upper:]' This was caused by commit af5d0c36, 21-10-2007, "tr: do not reject an unmatched [:lower:] or [:upper:] in SET1" This misaligned spec was allowed by extending the class: LC_ALL=C tr '[:upper:] ' '[:lower:]' * src/tr.c (validate_case_classes): A new function to check alignment of case conversion classes. Also it adjusts the length of the sets so that locales with different numbers of upper and lower case characters, don't cause issues. (string2_extend): Disallow extending the case conversion class as in the above example. That is locale dependent and most likely not what the user wants. (validate): Do the simple test for "restricted" char classes earlier, so we don't redundantly do more expensive validation. (main): Remove the case class validation, and simplify. * tests/misc/tr-case-class: A new test to test the various alignment and locale issues, associated with case conversion. * tests/misc/tr: Move case conversion tests to new tr-case-class. * tests/Makefile.am: Reference the new test. * NEWS: Mention the fixes.

(find_bind_mount): A new function to return the bind mount for a file if any. (out_mount_mount): Print the bind mount for a file, or else the standard mount point given by the find-mount-point module. (usage): Document the %m format directive. * src/Makefile.am: Reference the refactored find-mount-point.c * po/POTFILES.in: Add find_mount_point.c to the translation list * doc/coreutils.texi (stat invocation): Document %m, and how it may differ from the mount point that df outputs. * test/misc/stat-mount: A new test to correlate mount points output from df and stat. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature * THANKS: Add the author Signed-off-by: Pádraig Brady <P@draigBrady.com>

2010-07-13sort: parallelize internal sortChen Guo
This patch is by Gene Auyeung, Chris Dickens, Chen Guo, and Mike Nichols, based off of a patch by Paul Eggert, Glen Lenker, et. al., with a basic heap implementation based off of the GDSL heap, originally by Nicolas Darnis. The number of sorts done in parallel is limited to the number of available processors by default, or can be further restricted with the --parallel option. On a dual-die, 8 core Intel Xeon, results show sorting with 8 threads is almost 4 times faster than using a single thread. Timings when sorting a 96MB file: THREADS TIME (s) 1 5.10 2 2.87 4 1.75 8 1.31 Single threaded sorting has also been improved, especially for cheaper comparison operations: COMMAND BEFORE (s) AFTER (s) sort 8.822 8.716 sort -g 10.336 10.222 sort -n 3.077 2.961 LANG=C sort 2.169 2.066 * bootstrap.conf: Add heap, pthread. * coreutils.texi (sort): Describe the new --parallel option. * gl/lib/heap.c: New file. Very basic heap implementation. * gl/lib/heap.h: New file. * gl/modules/heap: New file. * src/Makefile.am: Add LIB_PTHREAD. * src/sort.c: Include heap.h, nproc.h, pthread.h. (MAX_MERGE): New macro. (SUBTHREAD_LINES_HEURISTIC, PARALLEL_OPTION): New constants. (MERGE_END, MERGE_ROOT): New constants. (struct merge_node): New struct. (struct merge_node_queue): New struct. (sortlines temp): Remove declaration. (usage, long_options, main): New option, --parallel. (specify_nthreads): New function. (mergelines): New signature, to emphasize the fact that the HI area must be part of the destination. All callers changed. (sequential_sort): New function, renamed from sortlines.

2010-06-30tests: move most helper functions from test-lib.sh to new init.cfgJim Meyering
From there, they will be used by both test-lib.sh (as we phase it out) and the newer init.sh, to which all tests will migrate. * tests/test-lib.sh: Move most functions from here, ... * tests/init.cfg: ...to here. New file. * tests/Makefile.am (EXTRA_DIST): Add init.cfg.
2010-05-19tests: exercise du's --max-depth optionJim Meyering
* tests/Makefile.am (TESTS): Add du/max-depth. * tests/du/max-depth: New file.
