c0c50efdef Fix for BUG#8218: 
Remove TMP_TABLE_PARAM::copy_funcs_it. TMP_TABLE_PARAM is a member of JOIN which is 
copied via memcpy, and List_iterator_fast TMP_TABLE_PARAM::copy_funcs_it ends up 
pointing to the wrong List.

04974868a1 subselect.result, subselect.test:

igor@rurik.mysql.com
d3fa245363 subselect.result, subselect.test: 
Added test cases for bug #7351.
item_cmpfunc.cc:
  Fixed bug #7351: incorrect result for a query with a
  subquery returning empty set.
  If in the predicate v IN (SELECT a FROM t WHERE cond)
  v is null, then the result of the predicate is either
  INKNOWN or FALSE. It is FALSE if the subquery returns
  an empty set.
item_subselect.cc:
  Fixed bug #7351: incorrect result for a query with a
  subquery returning empty set.
  The problem was due to not a quite legal transformation
  for 'IN' subqueries. A subquery containing a predicate
  of the form
  v IN (SELECT a FROM t WHERE cond)
  was transformed into
  EXISTS(SELECT a FROM t WHERE cond AND (a=v OR a IS NULL)).
  Yet, this transformation is valid only if v is not null.
  If v is null, then, in the case when
  (SELECT a FROM t WHERE cond) returns an empty set the value
  of the predicate is FALSE, otherwise the result of the
  predicate is INKNOWN.
  The fix resolves this problem by changing the result
  of the transformation to
  EXISTS(SELECT a FROM t WHERE cond AND (v IS NULL OR (a=v OR a IS NULL)))
  in the case when v is nullable.
  The new transformation prevents applying the lookup
  optimization for IN subqueries. To make it still
  applicable we have to introduce guarded access methods.

statements". (Version #2 with after-review fixes).

To perform proper cleanup for statements that can contain subqueries

6c136f99bf Proposed fix for bug #5003 (subselect with MIN() and LIKE crashes server) 
We have next problem here:
active_index is wrong in the subselect's handler on the second val_int() call.
Optimizer sees that we can use index-read for that kind of condition,
and matching_cond() (sql/opt_sum.cc) doesn't. I suspect, proper solution is
to add appropriate code to the matching_cond() but now just added
missed initialization.

85b00b7fb5 Fixed Bug#2479, "dependant subquery with limit crash". 
The problem was that memory was free'd, but it was referenced
later. This free was unneccessary anyway, because join_free() /
JOIN::cleanup takes care of this later on.

Added test case into t/subselect.test for it.

Regards,
Jani

dff5b0a75b Fix for #1992 
This bug happens when a query, having subselects in the fields list,
needs temporary table.
Item_subselect::get_tmp_table_item isn't implemented and just returns
*this. So the tmp_table_item takes value not from temporary but
from original table.

cab1dc628c CLIENT_MULTI_QUERIES -> CLIENT_MULTI_STATEMENTS 
New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
ALTER TABLE table_name ... CHARACTER SET  ... now changes all char/varchar/text columns to the given character set
(One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
Removed compiler warnings
Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.
