2bbdf2403d Bug#6391 (binlog-do-db rules ignored)
CREATE DATABASE statement used the current database instead of the
  database created when checking conditions for replication.
  CREATE/DROP/ALTER DATABASE statements are now replicated based on
  the manipulated database.

Also, Item_sum_hybrid->charset was removed as redundant,
and switched to use collation.collation instead.

2bba55b57f After merge fixes
Added push_back(void *, MEM_ROOT *) to make some list-handling code easier that needs to be allocated in a different mem-root
(Before one had to change thd->mem_root ; push_back(); restore mem_root.

b903a129e2 Simpler arena swapping code
Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

167c9489fa A fix (bug #6441: Aggregate UDF in multi-table query crashes MySQL when returning multiple rows). 2004-11-06 09:37:30 +04:00
bar@mysql.com
5543f312b0 As it is wrong and confusing to associate any
character set with NULL, @a should be latin2
after this query sequence:

   SET @a=_latin2'string';
   SET @a=NULL;

I.e. the second query should not change the charset
to the current default value, but should keep the
original value assigned during the first query.
In order to do it, we don't copy charset
from the argument if the argument is NULL
and the variable has previously been initialized.

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

5abc3de22b A fix and test case for Bug#5985 ""prepare stmt from "select rand(?)"
crashes server." The fix makes Item_func_rand prepared-statements
aware plus it fixes the case when RAND is used in prepared
statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared
statement, so if some execution had set thd->time_zone_used
or thd->rand_used they would not be reset until next mysql_parse.
Some of post-review fixes done.

Under strict mode MySQL will generate an error message if there was any conversion when assigning data to a field.

dlenev@brandersnatch.localdomain
9ed038dd6f WL#1218 "Triggers". Some very preliminary version of patch.
Mostly needed for Monty for him getting notion what needed for triggers 
from new .FRM format. 

Things to be done:
- Right placement of trigger's invocations
- Right handling of errors in triggers (including transaction rollback)
- Support for priviliges
- Right handling of DROP/RENAME table (hope that it will be handled automatically
  with merging of .TRG into .FRM file)
- Saving/restoring some information critical for trigger creation and replication
  with their definitions (e.g. sql_mode, creator, ...)
- Replication

Already has some known bugs so probably not for general review.
