8828884f4c CSC#4385: slow sorting for UTF8 large table: 
my_strnxfrm_utf8 now requires 2 bytes per character
in filesort key, instead of 3 bytes per character.
Shorter filesort keys make sorting faster.

e3d6e6736b bug#7284: strnxfrm returns different results for equal strings 2005-01-13 18:12:04 +04:00
monty@mysql.com
67ce247965 Add support for up to VARCHAR (size up to 65535) 
Renamed HA_VAR_LENGTH to HA_VAR_LENGTH_PART
Renamed in all files FIELD_TYPE_STRING and FIELD_TYPE_VAR_STRING to MYSQL_TYPE_STRING and MYSQL_TYPE_VAR_STRING to make it easy to catch all possible errors
Added support for VARCHAR KEYS to heap
Removed support for ISAM
Now only long VARCHAR columns are changed to TEXT on demand (not CHAR)
Internal temporary files can now use fixed length tables if the used VARCHAR columns are short

2496e85b84 Bug#4521: unique key prefix interacts poorly with utf8. 
Fix for binary collations for MyISAM and HEAP BTREE.
This patch also changes trailing spaces behaviour for
binary collations. Binary collations now have PAD 
characteristic too.

f43093ec0e After merge fixes 
Added more DBUG statements
Ensure that we are comparing end space with BINARY strings
Use 'any_db' instead of '' to mean any database. (For HANDLER command)
Only strip ' ' when comparing CHAR, not other space-like characters (like \t)

a444a3449f Simplified 'wrong xxx name' error messages by introducing 'general' ER_WRONG_NAME error 
Cleaned up (and disabled part of) date/time/datetime format patch. One can't anymore change default read/write date/time/formats.
This is becasue the non standard datetime formats can't be compared as strings and MySQL does still a lot of datetime comparisons as strings
Changed flag argument to str_to_TIME() and get_date() from bool to uint
Removed THD from str_to_xxxx functions and Item class.
Fixed core dump when doing --print-defaults
Move some common string functions to strfunc.cc
Dates as strings are now of type my_charset_bin instead of default_charset()
Introduce IDENT_QUOTED to not have to create an extra copy of simple identifiers (all chars < 128)
Removed xxx_FORMAT_TYPE enums and replaced them with the old TIMESTAMP_xxx enums
Renamed some TIMESTAMP_xxx enums to more appropriate names
Use defines instead of integers for date/time/datetime string lengths
Added to build system and use the new my_strtoll10() function.

e0a0790ebb Fixed that multibyte charsets didn't honor multibyte 
sequence boundaries in functions LIKE and LOCATE in
the case of "binary" collation. Comparison was done
like if the strings were just a binary strings without
character set assumption.

5b50426f8f Some optimization in CHARSET_INFO: 
We don't need separate hash_sort() and hash_caseup()
  We don't need tosort(). strnxfrm will do the same.
