1087186657 Merge with 4.1 to get new thd->mem_root handling 2004-11-08 17:53:32 +02:00
monty@mysql.com
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

d3e520ce7e Port of cursors to be pushed into 5.0 tree: 
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.

a46d7542c9 This is first cset for WL#1394 "Optimize index merge when all involved index ranges include only values with equal keys" 
The main idea is to exploit the fact that key scans for "key=const" return ordered sequences of rowids.

3938ac5436 This ChangeSet Introdices Item_equal. 
The objects of this class represent multiple conjunctive equalities
in where conditions: =(f1,f2,...fn) <=> f1=f2 and f2= ... and =fn.
The objects are used to generate new possibale paths to access
the tables when executing a query.
They are also used to optimize the execution plan 
chosen by the optimizer for the query.
