a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement
execute a subtree with negation was replaced with equivalent
subtree without NOTs.
The problem was that although this transformation was permanent,
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(),
Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
THD::free_temporary_pool_for_ps_preparing(); they
were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
prepared statement, it points at the thd.
The rest of the patch contains mainly mechanical changes and
cleanups.

flags to correctly make transformations of query and storing them in memory of PS/SP
sql/sql_parse.cc:
cleunup unit for any query
sql/sql_prepare.cc:
made ancestor for Statement (Item_arena)
storing where moved to preparation
changed interface of reset_stmt_for_execute to use it is SP
do not restore where/order by/group by before first execution (but tables and unit can be chenged without execution and should be prepared (subqueries executes on demand))
sql/sql_select.cc:
storing where for SELECT/multi-DELETE/... and mark first execution
sql/sql_union.cc:
made ancestor for Statement (Item_arena)
sql/sql_update.cc:
storing where for UPDATE and mark first execution
mysql-test/r/subselect.result:
ALL/ANY test
mysql-test/t/subselect.test:
ALL/ANY test
sql/item_subselect.cc:
keep old engine & JOIN if we changed subquery Item, which allow avoid second all SELECT items fix_fields call with pervios clean up (because of second setup_tables which remove table->key_use and maybe something else)
keep list when we change Item in SELECT list
processing inserted max/min function (now JOIN::prepare will be called only once)
methods of changing item for subselect engines
sql/item_subselect.h:
change item & results procedure
sql/item_sum.cc:
Item_sum_hybrid::clear moved to .cc file (to keep .h clean and to make inserving/removing debug info easy)
sql/item_sum.h:
Item_sum_hybrid::clear moved to .cc file (to keep .h clean and to make inserving/removing debug info easy)
sql/sql_lex.cc:
note about new method
sql/sql_lex.h:
method for changing result of UNION JOINs
sql/sql_select.cc:
method for changing result in JOIN
