This file implements the Czech sorting for the MySQL database server (www.mysql.com). Due to some complicated rules the Czech language has for sorting strings, a more complex solution was needed than the one-to-one conversion table. To note a few, here is an example of a Czech sorting sequence: co < hlaska < hláska < hlava < chlapec < krtek It because some of the rules are: double char 'ch' is sorted between 'h' and 'i'. Accented character 'á' (a with acute) is sorted after 'a' and before 'b', but only if the word is otherwise the same. However, because 's' is sorted before 'v' in hlava, the accentness of 'á' is overridden. There are many more rules. This file defines functions my_strxfrm and my_strcoll for C-like zero terminated strings and my_strnxfrm and my_strnncoll for strings where the length comes as an parameter. Also defined here you will find function my_like_range that returns index range strings for LIKE expression and the MY_STRXFRM_MULTIPLY set to value 4 -- this is the ratio the strings grows during my_strxfrm. The algorithm has four passes, that's why we need four times more space for expanded string. This file also contains the ISO-Latin-2 definitions of characters.

The end of the string is either passed as parameter, or is *p == 0. This is hidden in the IS_END macro. In the first two passes, we compare word by word. So we make first and second pass on the first word, first and second pass on the second word, etc. If we come to the end of the string during the first pass, we need to jump to the last word of the second pass. End of pass is marked with value 1 on the output. For each character, we read it's value from the table. If the value is ignore (0), we go straight to the next character. If the value is space/end of word (2) and we are in the first or second pass, we skip all characters having value 0 -- 2 and switch the pass. If it's the compose character (255), we check if the double exists behind it, find its value. We append 0 to the end. Neformální popis algoritmu: procházíme řetězec zleva doprava konec řetězce poznáme podle *p == 0 pokud jsme došli na konec řetězce při průchodu 0, nejdeme na začátek, ale na uloženou pozici, protože první a druhý průchod běží současně konec vstupu (průchodu) označíme na výstupu hodnotou 1 načteme hodnotu z třídící tabulky jde-li o hodnotu ignorovat (0), skočíme na další průchod jde-li o hodnotu konec slova (2) a je to průchod 0 nebo 1, přeskočíme všechny další 0 -- 2 a prohodíme průchody jde-li o kompozitní znak (255), otestujeme, zda následuje správný do dvojice, dohledáme správnou hodnotu na konci připojíme znak 0 */ /* In March 2007 latin2_czech_cs was reworked by Alexander Barkov, to suite other MySQL collations better, and to be Falcon compatible. Changes: - Discarded word-by-word comparison on the primary and the secondary level. Comparison is now strictly done level-by-level (like the Unicode Collation Algorithm (UCA) does). - Character weights were derived from Unicode 5.0.0 standard. This is to make order of punctuation characters and digits more consistent with all other MySQL collations and UCA. The order is now: Controls, spaces, punctuations, digits, letters. It previously used to be: Punctuations, controls, some more punctuations, letters, digits. NOTE: A minor difference between this implementations and the UCA: German "LATIN SMALL LETTER SHARP S" does not expand to "ss". It is instead considered as secondary greater than "LATIN LETTER S", and thus sorted between "LATIN LETTER S" and "LATIN LETTER S WITH ACUTE". This allows to reduce *twice* disk space required for un-indexed ORDER BY (using the filesort method). As neither the original version of latin2_czech_cs expanded "SHARP S" to "ss", nor "SHARP S" is a part of Czech alphabet, this behavior should be ok. - Collation is now "PAD SPACE" like all other MySQL collations. It ignores trailing spaces on primary and secondary level. - SPACE and TAB characters are not ignorable anymore. Also, they have different weights on primary level, like in all other MySQL collations: SELECT 'a\t' < 'a ' -- returns true SELECT 'a\t' < 'a' -- returns true - Some other punctuation characters are not ignorable anymore, for better compatibility with UCA and other MySQL collations. */ #define ADD_TO_RESULT(dest, len, totlen, value) \ if ((totlen) < (len)) { dest[totlen] = value; } (totlen++); #define IS_END(p, src, len) (((char *)p - (char *)src) >= (len)) /* ml - a flag indicating whether automatically switch to the secondary level, or stop on the primary level */ #define NEXT_CMP_VALUE(src, p, pass, value, len, ml) \ while (1) \ { \ if (IS_END(p, src, len)) \ { \ /* when we are at the end of string */ \ /* return either 0 for end of string */ \ /* or 1 for end of pass */ \ value= pass < 3 && ml ? 1 : -1; \ if (pass != 3 && ml && len > 0) \ { \ p= src; \ pass++; \ } \ break; \ } \ /* not at end of string */ \ value = CZ_SORT_TABLE[pass][*p]; \ if (value == 0 && pass < 3) \ { p++; continue; } /* ignore value on levels 0,1,2 */ \ if (value == 255) \ { \ int i; \ for (i= 0; i < (int) array_elements(doubles); i++) \ { \ const char * pattern = doubles[i].word; \ const char * q = (const char *) p; \ int j = 0; \ while (pattern[j]) \ { \ if (IS_END(q, src, len) || (*q != pattern[j])) \ break; \ j++; q++; \ } \ if (!(pattern[j])) \ { \ value = (int)(doubles[i].outvalue[pass]); \ p= (const uchar *) q - 1; \ break; \ } \ } \ } \ p++; \ break; \ } /* Function strnncoll, actually strcoll, with Czech sorting, which expect the length of the strings being specified */ static int my_strnncoll_czech(const CHARSET_INFO * const cs __attribute__((unused)), const uchar *s1, size_t len1, const uchar *s2, size_t len2, bool s2_is_prefix) { int v1, v2; const uchar * p1, * p2; int pass1= 0, pass2= 0; if (s2_is_prefix && len1 > len2) len1=len2; p1= s1; p2= s2; do { int diff; NEXT_CMP_VALUE(s1, p1, pass1, v1, (int)len1, 1); NEXT_CMP_VALUE(s2, p2, pass2, v2, (int)len2, 1); if ((diff = v1 - v2)) return diff; } while (v1); return 0; } /* Compare strings, ignore trailing spaces */ static int my_strnncollsp_czech(const CHARSET_INFO * const cs __attribute__((unused)), const uchar *s, size_t slen, const uchar *t, size_t tlen, bool diff_if_only_endspace_difference __attribute__((unused))) { int level; for (level= 0; level <= 3; level++) { const uchar *s1= s; const uchar *t1= t; for (;;) { int sval, tval, diff; NEXT_CMP_VALUE(s, s1, level, sval, (int) slen, 0); NEXT_CMP_VALUE(t, t1, level, tval, (int) tlen, 0); if (sval < 0) { sval= virtual_space[level]; for (; tval >= 0 ;) { if ((diff= sval - tval)) return diff; NEXT_CMP_VALUE(t, t1, level, tval, (int) tlen, 0); } break; } else if (tval < 0) { tval= virtual_space[level]; for (; sval >= 0 ;) { if ((diff= sval - tval)) return diff; NEXT_CMP_VALUE(s, s1, level, sval, (int) slen, 0); } break; } if ((diff= sval - tval)) return diff; } } return 0; } /* Returns the number of bytes required for strnxfrm(). */ static size_t my_strnxfrmlen_czech(const CHARSET_INFO * const cs __attribute__((unused)), size_t len) { return len * 4 + 4; } /* Function strnxfrm, actually strxfrm, with Czech sorting, which expect the length of the strings being specified */ static size_t my_strnxfrm_czech(const CHARSET_INFO * const cs __attribute__((unused)), uchar *dst, size_t dstlen, uint nweights_arg, const uchar *src, size_t srclen, uint flags) { uint level; uchar *dst0= dst; uchar *de= dst + dstlen; if (!(flags & 0x0F)) /* All levels by default */ flags|= 0x0F; for (level= 0; level <= 3; level++) { if (flags & (1 << level)) { uint nweights= nweights_arg; const uchar *p= src; int value; uchar *dstl= dst; for (; dst < de && nweights; nweights--) { NEXT_CMP_VALUE(src, p, level, value, (int) srclen, 0); if (value < 0) break; *dst++= value; } if (dst < de && nweights && (flags & MY_STRXFRM_PAD_WITH_SPACE)) { uint pad_length= de - dst; set_if_smaller(pad_length, nweights); /* fill with weight for space character */ memset(dst, virtual_space[level], pad_length); dst+= pad_length; } my_strxfrm_desc_and_reverse(dstl, dst, flags, level); /* Add level delimiter */ if (dst < de) *dst++= level < 3 ? 1 : 0; } } return dst - dst0; } #undef IS_END /* */ /* ** Calculate min_str and max_str that ranges a LIKE string. ** Arguments: ** ptr Pointer to LIKE string. ** ptr_length Length of LIKE string. ** escape Escape character in LIKE.
