|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding two levels of optimization: 1. For every bytes pair [00..FF][00..FF] which: a. consists of two ASCII characters or makes a well-formed two-byte character b. whose total weight string fits into 4 weights (concatenated weight string in case of two ASCII characters, or a single weight string in case of a two-byte character) c. whose weight is context independent (i.e. does not depend on contractions or previous context pairs) store weights in a separate array of MY_UCA_2BYTES_ITEM, so during scanner_next() we can scan two bytes at a time. Byte pairs that do not match the conditions a-c are marked in this array as not applicable for optimization and scanned as before. 2. For every byte pair which is applicable for optimization in #1, and which produces only one or two weights, store weights in one more array of MY_UCA_WEIGHT2. So in the beginning of strnncoll*() we can skip equal prefixes using an even more efficient loop. This loop consumes two bytes at a time. The loop scans while the two bytes on both sides produce weight strings of equal length (i.e. one weight on both sides, or two weight on both sides). This allows to compare efficiently: - Context independent sequences consisting of two ASCII characters - Context independent 2-byte characters - Contractions consisting of two ASCII characters, e.g. Czech "ch". - Some tricky cases: "ss" vs "SHARP S" ("ss" produces two weights, 0xC39F also produces two weights)

* | | Change CHARSET_INFO character set and collaction names to LEX_CSTRINGMonty2021-05-191-3/+4
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removed 68 explict strlen() calls from the code. The following renames was done to ensure we don't use the old names when merging code from earlier releases, as using the new variables for print function could result in crashes: - charset->csname renamed to charset->cs_name - charset->name renamed to charset->coll_name Almost everything where mechanical changes except: - Changed to use the new Protocol::store(LEX_CSTRING..) when possible - Changed to use field->store(LEX_CSTRING*, CHARSET_INFO*) when possible - Changed to use String->append(LEX_CSTRING&) when possible Other things: - There where compiler issues with ensuring that all character set names points to the same string: gcc doesn't allow one to use integer constants when defining global structures (constant char * pointers works fine). To get around this, I declared defines for each character set name length.

| | | | | | | | | | | | | | | | | | | | | | | | 1. unused static inline functions are only removed at -xO4, otherwise test binaries will depend on various mysys symbols that they don't use. Link test with libmysys. 2. Sphinx - don't instantiate (explicitly) templates before they're defined. Or, rather, don't instantiate them explicitly at all. 3. GIS - don't use anonymous unions and structs.

| * | WL#5665: Removal of the autotools-based build systemDavi Arnaut2010-11-201-27/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The autotools-based build system has been superseded and is being removed in order to ease the maintenance burden on developers tweaking and maintaining the build system. In order to support tools that need to extract the server version, a new file that (only) contains the server version, called VERSION, is introduced. The file contents are human and machine-readable. The format is: MYSQL_VERSION_MAJOR=5 MYSQL_VERSION_MINOR=5 MYSQL_VERSION_PATCH=8 MYSQL_VERSION_EXTRA=-rc The CMake based version extraction in cmake/mysql_version.cmake is changed to extract the version from this file. The configure to CMake wrapper is retained for backwards compatibility and to support the BUILD/ scripts. Also, a new a makefile target show-dist-name that prints the server version is introduced. VERSION: Add top-level version file. cmake/mysql_version.cmake: Get version information from the top-level VERSION file. Do not cache the version components (MAJOR_VERSION, etc). Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.

* Bug#45012 my_like_range_cp932 generates invalid stringAlexander Barkov2010-07-262-0/+141
Problem: The functions my_like_range_xxx() returned badly formed maximum strings for Asian character sets, which made problems for storage engines. Fix: - Removed a number my_like_range_xxx() implementations, which were in fact dumplicate code pieces. - Using generic my_like_range_mb() instead. - Setting max_sort_char member properly for Asian character sets - Adding unittest/strings/strings-t.c, to test that my_like_range_xxx() return well-formed min and max strings. Notes: - No additional tests in mysql/t/ available. Old tests cover the affected code well enough.
