Add more checks for "out of memory" detection in range optimization
Added MAX_PASSWORD_LENGTH. This increased master-slave passwords to 32 bytes (Bug #766)
Fixed server crash on purge master logs or show master logs when binlog is off. (Bug #733)
Fixed problem with localtime -> gmt where some times resulted in
different (but correct) timestamps. Now MySQL should use the smallest
possible timestamp value in this case. (Bug 316)
Search first only 10 % of the LRU list for a replaceable block before doing an LRU flush; enable again flushing of close pages also in a flush list (checkpointing) flush
trx0trx.c:
Add forgotten return value (it was not used anywhere, fortunately)
ha_innodb.h, mysql_priv.h:
Move declaration of srv_buf_pool_max_modified_pct to ha_innodb.h and enclose it to denote it is a C variable, not C++
Added ALL as parameter option for all group functions.
Make join handling uniform. This allows us to use ',', JOIN and INNER JOIN the same way.
Sort NULL last if DESC is used (ANSI SQL 99 requirement)
Call pthread_mutex_destroy() on not used mutex.
Changed comments in .h and .c files from // -> /* */
Added detection of mutex on which one didn't call pthread_mutex_destroy()
Fixed bug in create_tmp_field() which causes a memory overrun in queries that uses "ORDER BY constant_expression"
Added optimisation for ORDER BY NULL
Free row buffer cache after each query for MyISAM tables.
Added table join option FORCE INDEX
Fixed core dump bug when connecting with hostname that could not be resolved.
Made keybuff_size longlong (To make show variables work similar on 32
and 64 bit systems)
Fixed some 'not initalized variable errors' in multi-table-update.
Fixed memory leak in multi-table-update.
Now all tests works under valgrind without any errors.
New (simpler) internal timestamp handling.
More debuging to heap tables.
Small cleanups to multi-table-delete
false -> 0 and true -> 1 (We should use TRUE and FALSE)
Add support for LIMIT # OFFSET #
Changed lock handling: Now all locks should be stored in TABLE_LIST instead of passed to functions.
Don't call query_cache_invalidate() twice in some cases
mysql_change_user() now clears states to be equal to close + connect.
Fixed a bug with multi-table-update and multi-table-delete when used with LOCK TABLES
Fixed a bug with replicate-do and UPDATE
