maint: remove fstimeprec (variable precision time stamp) support

2010-11-13T10:41:02Z

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.

stat: use e.g. %.3X instead of %X.%3:X for sub-second precision

2010-11-06T14:24:49Z

* NEWS: Document this. * doc/coreutils.texi (stat invocation): Likewise. * gl/lib/fstimeprec.c, gl/lib/fstimeprec.h, gl/modules/fstimeprec: * gl/modules/fstimeprec-tests, gl/tests/test-fstimeprec.c: New files. * bootstrap.conf (gnulib_modules): Add fstimeprec. * src/stat.c: Include fstimeprec.h. Don't include xstrtol.h. (decimal_point, decimal_point_len): New static vars. (main): Initialize them. (epoch_sec, out_ns): Remove. (out_int, out_uint): Now returns whatever printf returned. (out_minus_zero, out_epoch_secs): New functions. (print_stat): Use out_epoch_sec instead of out_ns and epoch_sec. (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.

build: complete the rename of get_date

2010-10-05T18:12:30Z

* gnulib: Update to latest. * src/date.c (includes, batch_convert, main): Track rename. * src/touch.c (includes, get_reldate): Likewise. * doc/coreutils.texi (Top, Date input formats): Likewise. * bootstrap.conf (gnulib_modules): Likewise. * doc/Makefile.am (EXTRA_DIST): Likewise. * doc/.gitignore: Likewise. * bootstrap: Synchronize from upstream.

maint: update gnulib

2010-09-30T21:29:07Z

* gnulib: Update to latest. * bootstrap.conf (gnulib_modules): Reflect new module name. * bootstrap: Resync from upstream.

build: use gnulib's new termios module

2010-09-18T19:32:18Z

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.

maint: don't use obsolete gnulib modules

2010-09-18T19:22:36Z

* bootstrap.conf (gnulib_modules): Use calloc-gnu, malloc-gnu and realloc-gnu modules, rather than calloc, malloc and realloc. The shorter-named modules are now deprecated. (obsolete_gnulib_modules): Remove. (gnulib_modules): Remove raise, strbprk; they're obsolete, too. Move strtod, strtol here, from obsolete_gnulib_modules.

maint: update to latest gnulib

2010-09-17T14:42:52Z

* gnulib: Update to latest. * bootstrap.conf (gnulib_modules): Add fdutimensat. * src/touch.c (touch): Use fdutimensat instead of gl_futimens.

build: use gettext-h, not gettext

2010-09-04T12:24:57Z

* bootstrap.conf (gnulib_modules): Use gettext-h, not gettext. The latter is overkill for a package that uses AM_GNU_GETTEXT([external]...

fadvise: new module providing a simpler interface to posix_fadvise

2010-07-22T00:03:48Z

* 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.

sort: parallelize internal sort

2010-07-13T00:44:46Z

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. Signed-off-by: Pádraig Brady
