check return values.

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.

(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.
|
|

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,

(isaac_seed, isaac_refill): Adjust to new API.
* gl/lib/randread.c: Include sys/time.h.

|
|
* 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.

(nonce_device): New static var.
(randread_new): Use nonce device if available.

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.
|
|
* gl/lib/heap.c (heap_alloc): Use xnmalloc rather than xmalloc,
to avoid pathological overflow.
|
|
* 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.

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.

(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.

* gl/lib/ino-map.c (ino_hash): Declare "i" as unsigned int.
Use an intermediate variable for the for-loop upper bound,
so it's a little more readable. Adjust comment.
* gl/lib/di-set.c (di_ent_hash): Likewise.
|

Problem reported by Jim Meyering in:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6524#74

not incorrectly warn about shifting by 64-bits in unreachable code.

and now private. 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.

* 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.
|
|
* 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.
(ambsalign): A prototype for the new wrapper.

most TABs in indentation have been converted to spaces by running
this command: f=tempname.c.diff; patch-xform $f > k && mv k $f

Counterpart to commit 8fe40b84bd8, since test-link.c uses rename,

A replacement getgroups is now guaranteed to exist, but it may
fail with ENOSYS. mgetgroups is moved to gnulib, and now takes
gid_t instead of GETGROUPS_T (but setgroups still needs GETGROUPS_T).

cat, head, ptx, shuf, tac, tail, tee, tr, and uniq used freopen
on stdout, and were potentially vulnerable. dircolors, du, and
tsort only used it on stdin, which is unaffected by freopen_safer,
but this covers all uses for consistency.
* cfg.mk (sc_require_stdio_safer): New rule.
* gl/modules/xfreopen (Depends-on): Add freopen-safer.
* gl/lib/xfreopen.c (includes): Use stdio--.h.

In glibc 2.11 and gnulib, gen_tempname added a parameter
suffixlen (unfortunately, it is typed as int rather than
size_t, for historical compatibility to a poor choice by BSD).
* gnulib: Import latest changes.
* gl/lib/tempname.h.diff: Accommodate new suffixlen parameter.
* gl/lib/tempname.c.diff (check_x_suffix): Allow for X in suffix
beyond x_suffix_len.
(gen_tempname_len): Add suffixlen parameter.
(__gen_tempname): Update caller.
* src/mktemp.c (mkstemp_len, mkdtemp_len): Update callers.

Diffs are more robust than wholesale replacement, because bootstrap
will inform us of any incompatible changes made in upstream gnulib.
* gl/lib/tempname.h: Change...
* gl/lib/tempname.h.diff: ...to diff.
* gl/lib/tempname.c: Change...
