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.

mbsalign: avoid warning with Solaris 10 cc

2010-10-14T05:41:17Z

* gl/lib/mbsalign.c: Include 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.

maint: ensure the mbsalign module is C89 compatible

2010-10-01T15:30:31Z

This module may be moved to gnulib at some stage, so keep it C89 compatible. * gl/lib/mbsalign.c (mbsalign): Declare variables at start of scope (ambsalign): Likewise * gl/lib/mbsalign.h: Remove trailing comma from enum Reported by Andrei Suhan

sort: make struct heap private

2010-07-26T04:18:35Z

* 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.

sort: use more-consistent style with const

2010-07-26T02:25:09Z

* 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.

randread: run 2x faster on 64-bit hosts, don't assume no padding bits

2010-07-23T22:08:36Z

* 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 , 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.

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.

randread: use /dev/urandom to seed, not just getpid etc

2010-07-20T16:51:12Z

* 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.

randread: don't require -lrt

2010-07-16T22:49:05Z

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 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.
