2000-08-27 Bruno Haible <haible@clisp.cons.org>
* string/strxfrm.c (strxfrm, wcsxfrm): Include <sys/param.h>.
If nrules == 0 and srclen < n, copy only srclen + 1 characters.
* sysdeps/generic/getdomain.c (getdomainname): Include <sys/param.h>.
If the result is fits in the buffer, copy only as many bytes as needed.
* sysdeps/generic/_strerror.c (__strerror_r): Don't zero-fill the
buffer after copying numbuf into it.
* sysdeps/mach/_strerror.c (__strerror_r): Likewise.
2000-08-27 Bruno Haible <haible@clisp.cons.org>
* posix/confstr.c (confstr): When string_len > len, NUL-terminate
the result. When string_len < len, don't clear the rest of the buffer.
2000-08-27 Bruno Haible <haible@clisp.cons.org>
Support for new LC_COLLATE format.
* locale/coll-lookup.h: New file.
* locale/weightwc.h (findidx): When size == 0, call
collidx_table_lookup.
* wcsmbs/wcscoll.c: Include coll-lookup.h.
* wcsmbs/wcsxfrm.c: Likewise.
* posix/fnmatch.c: Likewise.
* posix/fnmatch_loop.c (internal_fnwmatch): When size == 0, call
collseq_table_lookup.
* locale/programs/3level.h: New file.
* locale/programs/ld-ctype.c: (wcwidth_table, wctrans_table): Define
by including "3level.h".
* locale/programs/ld-collate.c (wchead_table, collidx_table,
collseq_table): New types, defined by including "3level.h".
(locale_collate_t): New wcheads_3level, wcseqorder_3level fields.
(encoding_mask, encoding_byte): Remove.
(utf8_encode): Use simple shifts instead.
(collate_finish): When !oldstyle_tables, set plane_size and plane_cnt
to 0, and initialize and fill wcheads_3level and wcseqorder_3level.
(collate_output): New local variable tablewc_3level. When
!oldstyle_tables, set table_size to 0 and names to NULL and fill
tablewc_3level instead of tablewc. Change format of TABLEWC and
COLLSEQWC entries written to the file.
* locale/C-collate.c (collseqwc): Change format.
(_nl_C_LC_COLLATE): Set HASH_SIZE and HASH_LAYERS to 0, change format
of COLLSEQWC.
* locale/Makefile (distribute): Add coll-lookup.h, programs/3level.h.
2000-08-27 Bruno Haible <haible@clisp.cons.org>
* locale/programs/ld-ctype.c (MAX_CHARNAMES_IDX): New macro.
(locale_ctype_t): New charnames_idx field.
(ctype_startup): Initialize charnames_idx field.
(find_idx): Speed up dramatically by using charnames_idx inverse table.
2000-08-27 Bruno Haible <haible@clisp.cons.org>
* locale/C-ctype.c: Switch to new locale format.
(_nl_C_LC_CTYPE_names): Remove array.
(STRUCT_CTYPE_CLASS): New macro.
(_nl_C_LC_CTYPE_class_{upper,lower,alpha,digit,xdigit,space,print,
graph,blank,cntrl,punct,alnum}, _nl_C_LC_CTYPE_map_{toupper,tolower}):
New three-level tables.
(_nl_C_LC_CTYPE_width): Change from array to three-level table.
(_nl_C_LC_CTYPE): Fix nstrings value. Set HASH_SIZE and HASH_LAYERS
to 0. Change WIDTH format. Set CLASS_OFFSET and MAP_OFFSET. Add
12 class tables and 2 map tables at the end.
* ctype/ctype-info.c (_nl_C_LC_CTYPE_names): Remove declaration.
(_nl_C_LC_CTYPE_class_{upper,lower,alpha,digit,xdigit,space,print,
graph,blank,cntrl,punct,alnum}, _nl_C_LC_CTYPE_map_{toupper,tolower}):
New declarations.
(b): Remove trailing semicolon.
(__ctype_names, __ctype_width): Don't initialize.
(__ctype32_wctype, __ctype32_wctrans, __ctype32_width): Initialize.
2000-08-27 Bruno Haible <haible@clisp.cons.org>
* elf/dl-load.c (open_path): Add a argument telling whether *dirsp
is guaranteed to be allocated with the same malloc() and may be
passed to free().
(_dl_map_object): Update open_path calls. If rtld_search_dirs has
been set to empty by an earlier open_path call, don't pass it again.
