unknown	634d3991ab	Bug #23184 : SELECT causes server crash 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()	19 years ago

unknown	a2066982f1	Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used In a simple queries a result of the GROUP_CONCAT() function was always of varchar type. But if length of GROUP_CONCAT() result is greater than 512 chars and temporary table is used during select then the result is converted to blob, due to policy to not to store fields longer than 512 chars in tmp table as varchar fields. In order to provide consistent behaviour, result of GROUP_CONCAT() now will always be converted to blob if it is longer than 512 chars. Item_func_group_concat::field_type() is modified accordingly. mysql-test/t/func_gconcat.test: Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used mysql-test/r/func_gconcat.result: Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used sql/unireg.h: Added the CONVERT_IF_BIGGER_TO_BLOB constant sql/sql_select.cc: Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used The unnamed constant 255 in the create_tmp_field() and create_tmp_field_from_item() functions now defined as the CONVERT_IF_BIGGER_TO_BLOB constant. The create_tmp_field() function now converts the Item_sum string result to a blob field based on its char length. sql/item_sum.h: Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used To the Item_func_group_concat calls added the member function field_type() which returns the BLOB or VAR_STRING type based on the items length. sql/item_func.cc: Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used In the Item_func::tmp_table_field() function the unnamed constant 255 is changed to the CONVERT_IF_BIGGER_TO_BLOB constant. The Item_func::tmp_table_field() function now measures the result length in chars rather than bytes when converting string result to a blob.	20 years ago

unknown	b25315469e	Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries The GROUP_CONCAT uses its own temporary table. When ROLLUP is present it creates the second copy of Item_func_group_concat. This copy receives the same list of arguments that original group_concat does. When the copy is set up the result_fields of functions from the argument list are reset to the temporary table of this copy. As a result of this action data from functions flow directly to the ROLLUP copy and the original group_concat functions shows wrong result. Since queries with COUNT(DISTINCT ...) use temporary tables to store the results the COUNT function they are also affected by this bug. The idea of the fix is to copy content of the result_field for the function under GROUP_CONCAT/COUNT from the first temporary table to the second one, rather than setting result_field to point to the second temporary table. To achieve this goal force_copy_fields flag is added to Item_func_group_concat and Item_sum_count_distinct classes. This flag is initialized to 0 and set to 1 into the make_unique() member function of both classes. To the TMP_TABLE_PARAM structure is modified to include the similar flag as well. The create_tmp_table() function passes that flag to create_tmp_field(). When the flag is set the create_tmp_field() function will set result_field as a source field and will not reset that result field to newly created field for Item_func_result_field and its descendants. Due to this there will be created copy func to copy data from old result_field to newly created field. mysql-test/t/func_gconcat.test: Added test for bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries mysql-test/r/func_gconcat.result: Added test for bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries sql/sql_table.cc: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added 0 as a last parameter to create_tmp_field() to force old behaviour. sql/sql_select.cc: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the flag 'make_copy_field' to create_tmp_field(), so that for Item_result_field descendants create_tmp_field() sets the item's result field as a source field and deny resetting that result field to a new value. sql/sql_class.h: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the flag 'force_copy_fields' to the structure TMP_TABLE_PARAM in order to make create_tmp_field() force the creation of 'copy_field' objects. sql/mysql_priv.h: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the bool parameter 'make_copy_field' to create_tmp_field(). sql/item_sum.cc: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added initialization of the force_copy_fields flag and passing it to create_tmp_table() through TMP_TBLE_PARAM in the Item_func_group_concat and Item_sum_count_distinct member functions. sql/item_sum.h: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the flag 'force_copy_fields' to the Item_func_group_concat and Item_sum_count_distinct classes.	20 years ago

unknown	095b686c09	Fix for bug#4912 "mysqld crashs in case a statement is executed 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. mysql-test/r/ps.result: Test results updated (test case for Bug#4912) mysql-test/t/ps.test: A test case for Bug#4912 "mysqld crashs in case a statement is executed a second time" sql/item_cmpfunc.cc: current_statement -> current_arena sql/item_subselect.cc: Statement -> Item_arena, current_statement -> current_arena sql/item_subselect.h: Item_subselect does not need to save thd->current_statement. sql/item_sum.cc: Statement -> Item_arena sql/item_sum.h: Statement -> Item_arena sql/mysql_priv.h: Statement -> Item_arena sql/sql_base.cc: current_statement -> current_arena sql/sql_class.cc: - Item_arena - convenient set_n_backup_statement, restore_backup_statement (nice idea, Sanja) sql/sql_class.h: - Item_arena: backport from 5.0 - allocate_temporary_pool_for_ps_preparing, free_temporary_pool_for_ps_preparing removed. sql/sql_derived.cc: current_statement -> current_arena sql/sql_lex.cc: current_statement -> current_arena sql/sql_parse.cc: Deploy invariant that thd->free_list never contains junk items (backport from 5.0). sql/sql_prepare.cc: - backporting Item_arena - no need to allocate_temporary_pool_for_ps_preparing(). sql/sql_select.cc: Fix for bug#4912 "mysqld crashs in case a statement is executed a second time": if this is the first execute of a prepared statement, negation elimination is done in memory of the prepared statement. sql/sql_union.cc: Backporting Item_arena from 5.0.	21 years ago
