Item::val_xxx() may be called by the server several times at execute time for a single query. Calls to val_xxx() may be very expensive and sometimes (count(distinct), sum(distinct), avg(distinct)) not possible. To avoid that problem the results of calculation for these aggregate functions are cached so that val_xxx() methods just return the calculated value for the second and subsequent calls. mysql-test/r/func_group.result: Bug #23184: SELECT causes server crash - test case mysql-test/t/func_group.test: Bug #23184: SELECT causes server crash - test case sql/item_sum.cc: Bug #23184: SELECT causes server crash - caching of the aggregate function results so no need to recalculate at val_xxx() sql/item_sum.h: Bug #23184: SELECT causes server crash - caching of the aggregate function results so no need to recalculate at val_xxx()

select OK. The SQL parser was using Item::name to transfer user defined function attributes to the user defined function (udf). It was not distinguishing between user defined function call arguments and stored procedure call arguments. Setting Item::name was causing Item_ref::print() method to print the argument as quoted identifiers and caused views that reference aggregate functions as udf call arguments (and rely on Item::print() for the text of the view to store) to throw an undefined identifier error. Overloaded Item_ref::print to print aggregate functions as such when printing the references to aggregate functions taken out of context by split_sum_func2() Fixed the parser to properly detect using AS clause in stored procedure arguments as an error. Fixed printing the arguments of udf call to print properly the udf attribute. mysql-test/r/udf.result: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - test cases mysql-test/t/udf.test: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - test cases sql/item.cc: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - Don't print the refs to SUM functions as refs. sql/item_func.cc: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - print the aliases in the udf calls sql/item_func.h: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - print the aliases in the udf calls sql/sql_lex.cc: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - disable aliases for arguments in stored routine calls sql/sql_lex.h: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - disable aliases for arguments in stored routine calls sql/sql_yacc.yy: Bug #21809: Error 1356 while selecting from view with grouping though underlying select OK. - disable aliases for arguments in stored routine calls - fix bison duplicate symbol warnings

Repair table could crash a server if there is not sufficient memory (myisam_sort_buffer_size) to operate. Affects not only repair, but also all statements that use create index by sort: repair by sort, parallel repair, bulk insert. Return an error if there is not sufficient memory to store at least one key per BUFFPEK. Also fixed memory leak if thr_find_all_keys returns an error. myisam/sort.c: maxbuffer is number of BUFFPEK-s for repair. It is calculated as records / keys. keys is number of keys that can be stored in memory (myisam_sort_buffer_size). There must be sufficient memory to store both BUFFPEK-s and keys. It was checked correctly before this patch. However there is another requirement that wasn't checked: there must be sufficient memory for at least one key per BUFFPEK, otherwise repair by sort/parallel repair cannot operate. Return an error if there is not sufficient memory to store at least one key per BUFFPEK. Also fixed memory leak if thr_find_all_keys returns an error. mysql-test/r/repair.result: A test case for BUG#23175. mysql-test/t/repair.test: A test case for BUG#23175.

list using a function When executing dependent subqueries they are re-inited and re-exec() for each row of the outer context. The cause for the bug is that during subquery reinitialization/re-execution, the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join() and the local variable in 'sortorder' in create_sort_index(), which is allocated by make_unireg_sortorder(). Care must be taken not to allocate anything into the thread's memory pool while re-initializing query plan structures between subquery re-executions. All such items mush be cached and reused because the thread's memory pool is freed at the end of the whole query. Note that they must be cached and reused even for queries that are not otherwise cacheable because otherwise it will grow the thread's memory pool every time a cacheable query is re-executed. We provide additional members to the JOIN structure to store references to the items that need to be cached. mysql-test/r/subselect.result: Bug#21798: memory leak during query execution with subquery in column list using a function - test case mysql-test/t/subselect.test: Bug#21798: memory leak during query execution with subquery in column list using a function - test case sql/mysql_priv.h: Bug#21798: memory leak during query execution with subquery in column list using a function - cache the entities allocated in the threads memory pool by JOIN::exec (). sql/sql_delete.cc: Bug#21798: memory leak during query execution with subquery in column list using a function - cache the SORT_ORDER, TABLE * and JOIN_TAB allocated in the thread's memory pool by JOIN::exec (). sql/sql_select.cc: Bug#21798: memory leak during query execution with subquery in column list using a function - cache the SORT_ORDER, TABLE * and JOIN_TAB allocated in the thread's memory pool by JOIN::exec (). sql/sql_select.h: Bug#21798: memory leak during query execution with subquery in column list using a function - cache the SORT_ORDER, TABLE * and JOIN_TAB allocated in the thread's memory pool by JOIN::exec (). sql/sql_table.cc: Bug#21798: memory leak during query execution with subquery in column list using a function - cache the SORT_ORDER, TABLE * and JOIN_TAB allocated in the thread's memory pool by JOIN::exec (). sql/sql_update.cc: Bug#21798: memory leak during query execution with subquery in column list using a function - cache the SORT_ORDER, TABLE * and JOIN_TAB allocated in the thread's memory pool by JOIN::exec ().

When using index for group by and range access the server isolates a set of ranges based on the conditions over the key parts of the index used. Then it uses only the ranges over the GROUP BY fields to jump from one group to another. Since the GROUP BY fields may form a prefix over the index, we may use only a prefix of the ranges produced by the range optimizer. Each range contains a notion on whether it includes its border values. The problem is that when using a range prefix, the last range is open because it assumes that there is a range on the next keypart. Thus when we use a prefix range as it is, it excludes all border values. The solution is when ignoring the suffix of the range conditions (to jump over the GROUP BY prefix only) the server must change the remaining intervals so they always contain their borders, e.g. if the whole range was : (1,-inf) <= (<group_by_col>,<min_max_arg_col>) < (1, 3) we must make (1) <= (<group_by_col>) <= (1) because (a,b) < (c1,c2) means : a < c1 OR (a = c1 AND b < c2). mysql-test/r/group_min_max.result: Bug #22342: No results returned for query using max and group by - test case mysql-test/t/group_min_max.test: Bug #22342: No results returned for query using max and group by - test case sql/opt_range.cc: Bug #22342: No results returned for query using max and group by - open the intervals for prefix select when there are more conditions than used for the prefix search. sql/opt_range.h: Bug #22342: No results returned for query using max and group by - open the intervals for prefix select when there are more conditions than used for the prefix search.

strings MySQL is setting the flag HA_END_SPACE_KEYS for all the keys that reference text or varchar columns with collation different than binary. This was done to handle correctly the situation where a lookup on such a key may return more than 1 row because of the presence of many rows that differ only by the amount of trailing space in the table's string column. Inserting such values however appears to violate the unique checks on INSERT/UPDATE. Thus that flag must not be set as it will prevent the optimizer from choosing a faster access method. This fix removes the setting of the HA_END_SPACE_KEYS flag. include/my_base.h: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - disabled HA_END_SPACE_KEY as it's no longer needed mysql-test/r/func_str.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - fixed explain in an existing case mysql-test/r/merge.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - fixed explain in an existing case mysql-test/r/select.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - test case mysql-test/r/subselect.result: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - fixed explain in an existing case mysql-test/t/select.test: Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on strings - test case
