Run "make update-copyright".
2012-01-09maint: straggler *.[ch] files: convert more `...' to '...'Jim Meyering
The preceding commands ignored .[ch] files in lib/ and gl/. This is what I should have been doing from the start: git grep -l '`.*'\' $(g ls-files |grep '\.[ch]$') \ | xargs perl -pi -e 's/`(.+?'\'')/'\''$1/'

This avoids spurious diagnostics when running our "bootstrap" script. * gl/modules/heap: Append colon after "License". * gl/modules/randint: Likewise. * gl/modules/randperm: Likewise. * gl/modules/randread: Likewise. Reported by Stefano Lattarini. Diagnosed by Bruno Haible.
2011-10-30maint: avoid new "make syntax-check" failure due to stdalign definitionJim Meyering
* gl/modules/randread (Depends-on): Add stdalign. * gl/lib/randread.c: Include <stdalign.h>, so we can ... [!_STRING_ARCH_unaligned]: remove definition of stdalign.
2011-10-27build: avoid bootstrap failure when using patch-2.5.8Jim Meyering
* gl/modules/tempname.diff: Regenerate to correct bogus offsets and adjust for 1-line offset. Eric Blake reported that this patch failed to apply when using patch-2.5.8. Note that it applies fine using patch-2.6.1.

2011-08-08mktemp: stir in enough entropy (Bug#6683)Paul Eggert
* gl/lib/tempname.c.diff (gen_tempname_len): Use x_suffix_len bytes' worth of entropy, not 8 bytes.

* configure.ac (WARN_CFLAGS): Add -Wsuggest-attribute=const, -Wsuggest-attribute=pure and -Wsuggest-attribute=noreturn. (GNULIB_WARN_CFLAGS): But do not add them here... yet. * src/chown-core.h (chopt_free, uid_to_name): Add function attribute(s). * src/copy.c (is_ancestor, valid_options): Likewise. * src/copy.h (chown_failure_ok): Likewise. * src/dd.c (operand_matches, operand_is): Likewise. * src/df.c (selected_fstype, excluded_fstype): Likewise. * src/expr.c (null looks_like_integer): Likewise. * src/md5sum.c (hex_digits): Likewise. * src/od.c (get_lcm): Likewise. * src/pathchk.c (component_start, component_len): Likewise. * src/pinky.c (count_ampersands): Likewise. * src/pr.c (cols_ready_to_print): Likewise. * src/ptx.c (search_table): Likewise. * src/sort.c (find_unit_order): Likewise. * src/stty.c (mode_type_flag, string_to_baud, baud_to_value): Likewise. * src/system.h (gcd, lcm): Likewise. * src/tr.c (is_char_class_member, look_up_char_class): Likewise.

2011-06-17maint: use modules/tempname.diff file, not a replacement; update gnulibJim Meyering
Using a .diff is much more maintainable. Otherwise, changes in the gnulib module description file may not be noticed and merged promptly and may even result in subtle errors. Luckily, this time, the failure to propagate gnulib's changes to modules/tempname resulted only in an obvious link failure. * gl/modules/tempname: Remove file. * gl/modules/tempname.diff: Use a .diff file instead. * gnulib: Update submodule to latest.
2011-05-29maint: remove unnecessary gnulib .diff fileJim Meyering

* gl/lib/randperm.c (randperm_new): When the number of items to return H, is much smaller than the total number of items N, use a hash to represent the sparse permutations of the set N. This is currently enabled for N > 128K and N/H > 32. * tests/misc/shuf: Ensure shuf can quickly return 2 numbers from a large range. * gl/modules/randperm: Depend on hash. * NEWS: Mention the change.

2011-02-08tests: randread-tests: use macro.h not "#define ASSERT..."Jim Meyering
* gl/modules/randread-tests (Files): Add tests/macros.h * gl/tests/test-rand-isaac.c: Remove now-unneeded #include directives. (ASSERT): Remove definition. Instead, include "macros.h". Prompted by suggestions from Bruno Haible.
2011-02-07maint: move di-set and ino-map modules from ./gl to gnulibJim Meyering

2011-02-07di-set: provide a lookup methodJim Meyering
This is required for patch, and hence is about to move to gnulib. * gl/lib/di-set.c (di_set_lookup): New function. * gl/lib/di-set.h: Declare it. * gl/tests/test-di-set.c (main): Exercise it. The bug was introduced on 2004-12-04 via commit 7380cf79.
2011-01-01maint: update all copyright year number rangesJim Meyering

2010-11-13maint: remove fstimeprec (variable precision time stamp) supportJim Meyering
The implementation of variable-precision time stamps relied on heuristics that made the output subtly nondeterministic, or at least hard to reproduce: http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/21531/focus=21538 So, for now at least, we're removing that feature. * bootstrap.conf (gnulib_modules): Remove fstimeprec. * gl/lib/fstimeprec.c, gl/lib/fstimeprec.h: Remove files. * gl/modules/fstimeprec, gl/modules/fstimeprec-tests: Likewise. * gl/tests/test-fstimeprec.c: Remove file.

(print_stat, print_it, usage): Remove the %:X-style formats. * tests/misc/stat-nanoseconds: Set TZ=UTC0 to avoid problems with weird time zones. Use a time stamp near the Epoch so that we don't have to worry about leap seconds. Redo test cases to match new behavior. * tests/touch/60-seconds: Change %Y.%:Y to %.9Y, to adjust to new behavior.
2010-10-13mbsalign: avoid warning with Solaris 10 ccPaul Eggert
* gl/lib/mbsalign.c: Include <stdint.h> for SIZE_MAX. Use SIZE_MAX rather than (size_t) -1, to avoid warning for "size_t x = -1" on Solaris 10 cc. * gl/modules/mbsalign (Depends-on): Add stdint.

2010-07-25sort: make struct heap privatePaul R. Eggert
* gl/lib/heap.c (struct heap): Move this here... * gl/lib/heap.h (struct heap): ... from here, as outside code no longer needs to access any of these members.
2010-07-25sort: use more-consistent style with constPaul R. Eggert
* src/sort.c (proctab_hasher, proctab_comparator, stream_open, xfopen): (open_temp, zaptemp, struct_month_cmp, begfield, limfield): (find_unit_order, human_numcompare, numcompare, general_numcompare): (count_tabs, keycompare, compare, compare_nodes, lock_node): (unlock_node, queue_destroy, queue_init, queue_insert, queue_pop): (write_unique, mergelines_node, check_insert, update_parent): (merge_loop, sortlines, struct thread_args, set_ordering): Prefer the style "T const" to "const T". * gl/lib/heap.h (struct heap, heap_alloc): Likewise. * gl/lib/heap.c (heap_default_compare, heapify_down, heapify_up): (heap_alloc): Likewise.
2010-07-23randread: run 2x faster on 64-bit hosts, don't assume no padding bitsPaul R. Eggert
* gl/lib/rand-isaac.c: Remove the I/O; this belongs elsewhere. Add support for ISAAC64. Port to hosts with padding bits. Add self to author list. Include <limits.h>, for CHAR_BIT. Don't include string.h, sys/time.h, unistd.h. (min, just): New functions. (IF32): New macros. (ind, ISAAC_STEP, isaac_refill, mix, isaac_init, isaac_seed): Add support for ISAAC64. Port to hosts with padding bits. (ind): Now an inline function rather than a macro; no need for it to be a macro with modern compilers. (ISAAC_STEP): Renamed from isaac_step, since it's not function-like. Don't bother to pass args that are always the same. All uses changed. (ISAAC_STEP, ISAAC_SEED): Move to inside the only function body that can use it. (ISAAC_MIX): Renamed from isaac_mix, since it's now a macro and is no longer function-like. Don't bother saving and restoring state; no longer needed now that we're not a function. All uses changed. (isaac_seed_start, isaac_seed_data, isaac_seed_finish): Remove. (isaac_seed): Take just the one arg; the caller now sets s->m. * gl/lib/rand-isaac.h: Use _GL_RAND_ISAAC_H to protect, instead of RAND_ISAAC_H. Try out " #" rather than "# " for indenting. (ISAAC_BITS_LOG, ISAAC_BITS): New macros. (ISAAC_WORDS_LOG): Renamed from ISAAC_LOG. (isaac_word): New type. All uses of uint32_t changed to isaac_word, to support ISAAC64. (struct isaac_state): Rename member MM to M, and make it public. (isaac_seed, isaac_refill): Adjust to new API. * gl/lib/randread.c: Include sys/time.h. (get_nonce): New function, containing the nonce stuff that used to be in rand-isaac.c but better belongs here. (randread_new): Use it. * gl/modules/randread (Depends-on): Add inline. * gl/modules/randread-tests: New file. * gl/tests/test-rand-isaac.c: New file.
2010-07-22fadvise: new module providing a simpler interface to posix_fadvisePádraig Brady

2010-07-20randread: use /dev/urandom to seed, not just getpid etcPaul R. Eggert
* gl/lib/rand-isaac.c (isaac_seed_start): New arg SEEDED. (isaac_seed): New args FD and BYTES_BOUND. Read from FD if possible. Don't bother with low-quality sources if FD has enough bytes. * gl/lib/rand-isaac.h: New size_t arg for isaac_seed. * gl/lib/randread.c: Include fcntl.h, unistd.h. (NAME_OF_NONCE_DEVICE): New #define. (nonce_device): New static var. (randread_new): Use nonce device if available.
2010-07-16randread: don't require -lrtPaul R. Eggert
Programs like 'sort' were linking to -lrt in order to get clock_gettime, but this was misguided: it wasted considerable resources while gaining at most 10 bits of entropy. Almost nobody needs the entropy, and there are better ways to get much better entropy for people who do need it. * gl/lib/rand-isaac.c (isaac_seed): Include <sys/time.h> not "gethrxtime.h". (isaac_seed): Use gettimeofday rather than gethrxtime. * gl/modules/randread (Depends-on): Depend on gettimeofday and not gethrxtime. * src/Makefile.am (mktemp_LDADD, shred_LDADD, shuf_LDADD, sort_LDADD): (tac_LDADD): Omit $(LIB_GETHRXTIME); no longer needed.
2010-07-14heap_alloc: avoid integer overflowJim Meyering
* gl/lib/heap.c (heap_alloc): Use xnmalloc rather than xmalloc, to avoid pathological overflow.
2010-07-13maint: heap.c: simplify dynamic allocationsPádraig Brady
* gl/lib/heap.c (heap_alloc): Use the fact that the xalloc routines will not return NULL. Also remove the redundant temporary variables. (heap_insert): From Jim Meyering, use x2nrealloc() which is simpler while handling overflow and increasing the size more efficiently. This reallocation is currently unused by coreutils in any case as it preallocates enough.
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. Merge in the functionality of sortlines_temp. (compare_nodes): New function. (lock_node, unlock_node): New functions. (queue_destroy): New function. (queue_init): New function. (queue_insert): New function. (queue_pop): New function. (write_unique): New function. (mergelines_node): New function. (check_insert): New function. (update_parent): New function. (merge_loop): New function. (sortlines): Rewrite to support and use parallelism, with a new signature. All callers changed. (struct thread_args): New struct. (sortlines_thread): New function. (sortlines_temp): Remove. (sort): New argument NTHREADS. All uses changed. Output moved to mergelines_node. (main): disable threading if we are sorting at random. * tests/Makefile.am (TESTS): Add misc/sort-benchmark-random. * tests/misc/sort-benchmark-random: New file.

All uses changed. (_ATTRIBUTE_NONNULL_): Don't assume C99. (di_set_alloc): Renamed from di_set_init, with no size arg. Now allocates the object rather than initializing it. For now, this no longer takes an initial size; we can put this back later if it is needed. * gl/lib/di-set.c: Include hash.h, ino-map.h, and limits.h instead of stdio.h, assert.h, stdint.h, sys/types.h (di-set.h includes that now), sys/stat.h, and verify.h.

2010-03-19maint: mbsalign: fix an edge case where we truncate too muchPádraig Brady
* gl/lib/mbsalign.c (mbsalign): Ensure the temporary destination buffer is big enough, as it may need to be bigger than the source buffer in the presence of single byte non printable chars. * gl/tests/test-mbsalign.c (main): Add a test to trigger the issue.
2010-03-19maint: update the mbsalign modulePádraig Brady
* gl/lib/mbsalign.c (mbsalign): Support the MBA_UNIBYTE_FALLBACK flag which reverts to unibyte mode if one can't allocate memory or if there are invalid multibyte characters present. Note memory is no longer dynamically allocated in unibyte mode so one can assume that mbsalign() will not return an error if this flag is present. Don't calculate twice, the number of spaces, when centering. Suppress a signed/unsigned comparison warning. (ambsalign): A new wrapper function to dynamically allocate the minimum memory required to hold the aligned string. * gl/lib/mbsalign.h: Add the MBA_UNIBYTE_FALLBACK flag and also document others that may be implemented in future.
