699a530a0a BUG#6034 - Error code 124: Wrong medium type.
Version for 4.1. Committed for merge.
If the result table is one of the select tables in INSERT SELECT,
we must not disable the result tables indexes before selecting.
mysql_execute_command() detects the match for other reasons and
adds the flag OPTION_BUFFER_RESULT to the 'select_options'. 
In this case the result is put into a temporary table first. 
Hence, we can defer the preparation of the insert
table until the result is to be used.

f0cf742fd3 Fix for BUG#7331.
The problem was that when a QUICK_SELECT access method is chosen,
test_if_skip_sort_order() discovered that the index being used
by the quick select will not deliver tuples in sorted order.
In this case test_if_skip_sort_order() tried to change the index
used by the quick select, but it didn't properly set the other
members of the quick select, and especially the range flags of
the ranges in QUICK_SELECT::ranges.

The fix re-invokes the function SQL_SELECT::test_quick_select
to correctly create a valid QUICK_SELECT object.

435b20aa68 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

sql_select.cc:
  Fixed the problem of bug reports #6307 and #6460.
  The reported wrong result sets were due to the fact that
  the added call of the fix_fields method for the built
  AND condition that joined WHERE and ON conditions
  broke ON expression, as it removed extra AND levels
  in the built condition. 
  It looks like that no attributes of the built condition
  are needed, so we don't have to call fix_fields here.

1d48aec228 A fix and test case for Bug#5987 "subselect in bool function
crashes server (prepared statements)": the bug was that all boolean
items always recovered its original arguments at statement cleanup 
stage.
This collided with Item_subselect::select_transformer, which tries to 
permanently change the item tree to use a transformed subselect instead of
original one.
So we had this call sequence for prepare:
mysql_stmt_prepare -> JOIN::prepare -> 
Item_subselect::fix_fields -> the item tree gets transformed ->
Item_bool_rowready_func2::cleanup, item tree is recovered to original
state, while it shouldn't have been;
mysql_stmt_execute -> attempts to execute a broken tree -> crash.
Now instead of bluntly recovering all arguments of bool functions in 
Item_bool_rowready_func2::cleanup, we recover only those
which were changed, and do it in one place.
There still would exist a possibility for a collision with subselect
tranformation, if permanent and temporary changes were performed at the 
same stage.
But fortunately subselect transformation is always done first, so it 
doesn't conflict with the optimization done by propogate_cond_constants.
Now we have: 
mysql_stmt_prepare -> JOIN::prepare -> subselect transformation 
permanently changes the tree -> cleanup doesn't recover anything, 
because nothing was registered for recovery.
mysql_stmt_execute -> JOIN::prepare (the tree is already transformed, 
so it doesn't change), JOIN::optimize -> 
propogate_cond_constants -> temporary changes the item tree 
with constants -> JOIN::execute -> cleanup -> 
the changes done by propogate_cond_constants are recovered, as
they were registered for recovery.

  It's crucial to add new items to the beginning of the recovery list,
  so that the recovery is performed in LIFO mode: otherwise if we 
  change one node of a tree twice, it will be recovered to some intermediate
  state.
sql/sql_select.cc:
  change_cond_ref_to_const and propogate_cond_constants are now responsible
  to register all changes of the item tree for recovery.
  The recovery is done using the centralized THD registry of
  changed tree items.

  field in all tables.

49bd559eb8 Fix for Bug#5034 "prepared "select 1 into @arg15", second
execute crashes server": we were deleting lex->result
after each execute, but prepared statements assumed that
it's left intact.
The fix adds cleanup() method to select_result hierarchy,
so that result objects can be reused.
Plus we now need to delete result objects more wisely.


mysql-test/r/ps.result:
  Test results fixed: test case for bug#5034
mysql-test/t/ps.test:
  A test case for bug#5034, few followups
sql/sql_class.cc:
  - fix warning in THD::THD
  - implementation of cleanup() for select_result hierarchy
  - select_export::send_eof was identical to 
    select_dump::send_eof: moved to the base class select_to_file.
  - Statement::end_statement() to end lex, free items, and
    delete possible select_result
sql/sql_class.h:
  - select_result::cleanup() declaration
  -
sql/sql_insert.cc:
  - implementation of select_insert::cleanup(): currently
    we always create a new instance of select_insert/
    select_create on each execute.
sql/sql_lex.cc:
  - with more complicated logic of freeing lex->result it's 
    easier to have it non-zero only if it points to a valid
    result.
sql/sql_lex.h:
  Now st_lex::st_lex is not empty.
sql/sql_parse.cc:
  mysql_execute_command():
  - delete select_result *result only if it was created in
    this function.
  - use end_statement() to cleanup lex and thd in the end of
    each statement.
  - no need to save THD::lock if this is explain. This save
    apparently left from times when derived tables were 
    materialized here, not in open_and_lock_tables.
sql/sql_prepare.cc:
  - call result->cleanup() in reset_stmt_for_execute
  - now Statement is responsible for freeing its lex->result.
sql/sql_select.cc:
  handle_select():
  - don't delete result, it might be needed
    for next executions
  - result is never null
