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.
