impossible WHERE/HAVING clause (subselect_single_select_engine::exec). Allocation and initialization of joined table list t1, t2... of subqueries like: NOT IN (SELECT ... FROM t1,t2,... WHERE 0) is optimized out, however server tries to traverse this list.

Grouping or ordering of long values in not indexed BLOB/TEXT columns with GBK or BIG5 charsets crashes the server. MySQL server uses sorting (the filesort procedure) in the temporary table to evaluate the GROUP BY clause in case of lack of suitable index. That procedure takes into account only first @max_sort_length bytes (system variable, usually 1024) of TEXT/BLOB sorting key string. The my_strnxfrm_gbk and my_strnxfrm_big5 fill temporary keys with data of whole blob length instead of @max_sort_length bytes length. That buffer overrun has been fixed.

1. Use 'dat' extension, because it is handled in Makefile.am; 2. Fix typo: the bug id is 35469, not 35649.

The problem was that LOAD DATA code (sql_load.cc) didn't take into account that there may be items, representing references to other columns. This is a usual case in views. The crash happened because Item_direct_view_ref was casted to Item_user_var_as_out_param, which is not a base class. The fix is to 1) Handle references properly; 2) Ensure that an item is treated as a user variable only when it is a user variable indeed; 3) Report an error if LOAD DATA is used to load data into non-updatable column.

Mixing aggregate functions and non-grouping columns is not allowed in the ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because of insufficient check. In order to check more thoroughly the new algorithm employs a list of outer fields used in a sum function and a SELECT_LEX::full_group_by_flag. Each non-outer field checked to find out whether it's aggregated or not and the current select is marked accordingly. All outer fields that are used under an aggregate function are added to the Item_sum::outer_fields list and later checked by the Item_sum::check_sum_func function.

Fixed interference between tests: Users were added but not properly removed. This caused later tests to fail.

Bug#21413 "Engine table handler used by multiple threads in REPLACE DELAYED" When executing a REPLACE DELAYED statement, the storage engine ::extra() method was invoked by a different thread than the thread which has acquired the handler instance. This did not cause problems within the current server and with the current storage engines. But it has the potential to confuse future storage engines. Added code to avoid surplus calls to extra() method in case of DELAYED which avoids calling storage engine from a different thread than expected. No test case. This change does not change behavior in conjunction with current storage engines. So it cannot be tested by the regression test suite.

View definition as SELECT ... FROM DUAL WHERE ... has valid syntax, but use of such view in SELECT or SHOW CREATE VIEW syntax causes unexpected syntax error. Server omits FROM DUAL clause when storing view body string in a .frm file for further evaluation. However, syntax of SELECT-witout-FROM query is more restrictive than SELECT FROM DUAL syntax, and doesn't allow the WHERE clause. NOTE: this syntax difference is not documented. View registration procedure has been modified to preserve original structure of view's body.
