da8a68b4ca Bug#17374: select ... like 'A%' operator fails to find value on columuns with key
Fixed that LIKE worked case insensitively for latin2_czech_cs,
which was wrong for a case sensitive collation.

197782605f BUG#11338 (logging of prepared statement w/ blob type)
In cp932, '\' character can be the second byte in a 
multi-byte character stream. This makes it difficult to use
mysql_escape_string. Added flag to indicate which languages allow
'\' as second byte of multibyte sequence so that when putting a prepared
statement into the binlog we can decide at runtime whether hex encoding
is really needed.

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.

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

e3b94d4ef5 Bug #6737: REGEXP gives wrong result with case sensitive collation:
- A new flag MY_CS_CSSORT was introduced for case sensitivity.
- Item_func_regexp doesn't substiture ICASE not only
  for binary collations but for case sensitive collations as well.

ebc3b3afac BTREE-indexes in HEAP tables can now be used to optimize ORDER BY
Don't read character set files if we are using only the default charset. In most cases the user will not anymore get a warning about missing character set files
Compare strings with space extend instead of space strip. Now the following comparisons holds:  "a" == "a " and "a\t" < "a". (Bug #3152).
Note: Because of the above fix, one has to do a REPAIR on any table that has an ascii character < 32 last in a CHAR/VARCHAR/TEXT columns.

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.
