(For 4.1 tables old 'VARCHAR' fields are converted to true VARCHAR in the next ALTER TABLE)
This ensures that one can use MySQL 5.0 privilege tables with MySQL 4.1
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
FOUND is not a reserved keyword anymore
Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT
Note that the 5.0 tree is not yet up to date: Sanja will have to fix multi-update-locks for this merge to be complete
Note: The following tests fails
- fulltext (Sergei has promised to fix)
- rpl_charset (Guilhem should fix)
- rpl_timezone (Dimitray has promised to fix)
Sanja needs to check out the calling of close_thread_tables() in sp_head.cc
various fixes (for mysql-test-run at least):
* accept --no-defaults
* 4.0 compatible password handling (only it no other argumensts, only if doesn't start with --)
ps_3innodb.test:
only run ps_3innodb.test if innodb is present
mysql-test-run.sh:
it's --verbose, not --verbose=1
bmove_allign -> bmove_align
Added OLAP function ROLLUP
Split mysql_fix_privilege_tables to a script and a .sql data file
Added new (MEMROOT*) functions to avoid calling current_thd() when creating some common objects.
Added table_alias_charset, for easier --lower-case-table-name handling
Better SQL_MODE handling (Setting complex options also sets sub options)
New (faster) assembler string functions for x86
Fixed bug in SELECT ... ORDER BY ... LIMIT
Fixed bug in ALTER TABLE and RENAME TABLE with --lower-case-table-names
Fixed hang when using --with-openssl
SHOW DATABASES
CREATE TEMPORARY TABLE
LOCK TABLES
REPLICATION SLAVE & REPLICATION CLIENT
SUPER
EXECUTE
All scripts & documentation is updated for this change.
Added better error messages for global privileges
Fixes for embedded server
Made key_cache more configurable
Fixed that one can change key blocksize in MyISAM
A lot of optimizations to make MyISAM slightly faster
