RESET MASTER, this breaks replication).
In the slave SQL thread, any DROP TEMPORARY TABLE is silently
converted to DROP TEMPORARY TABLE IF EXISTS, not to have irrelevant
"table does not exist". See comments in code or bug #186 for an example
of how irrelevant errors like this can arise.
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
Fixed comparision of log-binary name to handle comparison when file name extension wraps from .999 to .1000
Don't replicate CREATE/DROP DATABASE if wild_xxx_table=database.% is used.
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.
Extended max_allowed_packet for clients to 1G
Fixed bug in sending compressed rows >= 16M
Fix bug in skiping too long packets from clients.
Added checking of wrong command number sent by client.
Changed long packat handling to check for packets of length 0xffffff.
This does however break packet handling for older clients.
If you are using packets >= 16M then you need to upgrade client and server
after this patch.
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
Let MySQL 4.0 read 4.1 .frm files without 4.1 specific extensions
New variables @@rand_seed1 and @@rand_seed2 (used by replication)
DROP TEMPORARY TABLE
