2004-11-12 Ulrich Drepper <drepper@redhat.com>
* posix/Makefile (tests): Add bug-regex24.
* posix/bug-regex24.c: New file.
2004-11-12 Paolo Bonzini <bonzini@gnu.org>
* posix/regexec.c (check_dst_limits_calc_pos_1): Use the map to
cut recursive paths. Make exit condition more precise.

[BZ #535]
* time/difftime.c: Fix a double-rounding bug on hosts with
64-bit time_t and long double being IEEE double. Also, port
to more valid C99 hosts, even those that have padding bits.
Don't include <values.h> since it is marked as an obsolescent
interface. Include <limits.h>, <float.h>, and <stdint.h> instead.
(TYPE_BITS, TYPE_FLOATING, TYPE_SIGNED): New macros.
(subtract): New static function, that works correctly without
double-rounding, even on hosts with 64-bit time_t. Also cater
to hosts with padding bits.
(__difftime): Use it. Use DBL_MANT_DIG and LDBL_MANT_DIG to
determine whether floating types are wide enough: the old
test (which used sizeof) could in theory report the wrong results
on hosts with padding bits in floating-point values.

[BZ #542]
* sysdeps/generic/strtok_r.c [HAVE_CONFIG_H]: Include config.h.

this #ifdef.

Problem reported by Mark D. Baushke in
<http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00071.html>.

re_string_context_at): Add several branch predictions for
case-sensitive matching and no transition table being used.
2004-11-10 Ulrich Drepper <drepper@redhat.com>

* libio/bug-ungetc3.c: New test.
2004-11-08 Ulrich Drepper <drepper@redhat.com>
* posix/regcomp.c (utf8_sb_map): Define.
(free_dfa_content): Don't free dfa->sb_char if it's a pointer to
utf8_sb_map.
(init_dfa): Use utf8_sb_map instead of initializing memory when the
encoding is UTF-8.
* posix/regcomp.c (init_dfa): Get the codeset name outside glibc as
well. Check if it is spelled UTF8 as well as UTF-8, and check
case-insensitively. Set dfa->map_notascii manually when outside
glibc.
* posix/regex_internal.c (build_wcs_upper_buffer) [!_LIBC]: Enable
optimizations based on map_notascii.
* posix/regex_internal.h [HAVE_LANGINFO_H || HAVE_LANGINFO_CODESET
|| _LIBC]: Include langinfo.h.
* posix/regex_internal.h (struct re_backref_cache_entry): Add "more"
field.
* posix/regexec.c (check_dst_limits): Hoist computation of the source
and destination bkref_idx out of the loop. Pass it to
check_dst_limits_calc_pos.
(check_dst_limits_calc_pos_1): New function, containing the recursive
loop of check_dst_limits_calc_pos; uses the "more" field of
struct re_backref_cache to control the loop.
(check_dst_limits_calc_pos): Store into "boundaries" the position
relative to lim's start and end positions. Do not accept eclosures,
accept bkref_idx instead. Call check_dst_limits_calc_pos_1 to do the
work.

to control the loop. A big "if" was turned into a continue and the
function was reindented.

to control the loop.

field.

check_subexp fields. Move limits last.

fields. Callers adjusted.

Remove dead test for "node == sctx->bkref", and the cur_bkref_idx
variable.

value of re_node_set_insert.

to unsigned short int.

(struct user_fpregs_struct): Fix comment.
* sysdeps/i386/fpu/bits/mathdef.h (float_t, double_t): If

[BZ #487] This change is imported from gnulib.
* time/mktime.c (not_equal_tm) [DEBUG]: Remove redundant check.
2004-10-24 Paul Eggert <eggert@cs.ucla.edu>
[BZ #473]
* time/tst-mktime.c (main): Don't assume that mktime fails
when given time stamps before 1970. It returns negative
time_t values instead, for compatibility with BSD.
* time/tst-mktime2.c: New file.
* time/Makefile (tests): Add it.
[BZ #473] Import from gnulib. Revamp to avoid several problems near
time_t extrema, and on hosts with 64-bit time_t and 32-bit int.
This fixes Debian bug 177940.
* time/mktime.c (TIME_T_MIDPOINT): New macro.
(ydhms_diff): Renamed from ydhms_tm_diff, with a new signature,
which avoids overflow problems on hosts with 64-bit time_t and
32-bit int. All callers changed. Now an inline function.
Verify at compile-time that long int is wide enough to avoid
these overflow problems.
(guess_time_tm): New function.
(__mktime_internal): Use it. Avoid overflow when computing yday on
hosts with 64-bit long and 32-bit int. Remove tests for 69;
no longer needed. Use if rather than #ifdef for LEAP_SECONDS_POSSIBLE
so that the code is checked by more compilers.
Do not rely on floating point to probe: stick to integer arithmetic,
to avoid potential porting problems.
Repair potential overflow correctly in the Southern Hemisphere.
(localtime_offset): Add a FIXME for the case where time_t is unsigned.
