Alexander Barkov	482d3bfd80	Backporting WL#3759 Optimize identifier conversion in client-server protocol This patch provides performance improvements: - send_fields() when character_set_results = latin1 is now about twice faster for column/table/database names, consisting on ASCII characters. Changes: - Protocol doesn't use "convert" temporary buffer anymore, and converts strings directly to "packet". - General conversion optimization: quick conversion of ASCII strings was added. modified files: include/m_ctype.h - Adding a new flag. - Adding a new function prototype libmysqld/lib_sql.cc - Adding quick conversion method for embedded library: conversion is now done directly to result buffer, without using a temporary buffer. mysys/charset.c - Mark all dynamic ucs2 character sets as non-ASCII - Mark some dymamic 7bit and 8bit charsets as non-ASCII (for example swe7 is not fully ASCII compatible). sql/protocol.cc - Adding quick method to convert a string directly into protocol buffer, without using a temporary buffer. sql/protocol.h - Adding a new method prototype sql/sql_string.cc Optimization for conversion between two ASCII-compatible charsets: - quickly convert ASCII strings, switch to mc_wc->wc_mb method only when a non-ASCII character is met. - copy four ASCII characters at once on i386 strings/conf_to_src.c - Marking non-ASCII character sets with a flag. strings/ctype-extra.c - Regenerating ctype-extra.c by running "conf_to_src". strings/ctype-uca.c - Marking UCS2 character set as non-ASCII. strings/ctype-ucs2.c - Marking UCS2 character set as non-ASCII. strings/ctype.c - A new function to detect if a 7bit or 8bit character set is ascii compatible.	16 years ago

bar@mysql.com/bar.myoffice.izhnet.ru	4eebfd09c2	Bug#28875 Conversion between ASCII and LATIN1 charsets does not function (Regression, caused by a patch for the bug 22646). Problem: when result type of date_format() was changed from binary string to character string, mixing date_format() with a ascii column in CONCAT() stopped to work. Fix: - adding "repertoire" flag into DTCollation class, to mark items which can return only pure ASCII strings. - allow character set conversion from pure ASCII to other character sets.	19 years ago
