Non-upper-level INSERTs (the ones in the body of stored procedure, stored function, or trigger) into a table that have AUTO_INCREMENT column didn't affected the result of LAST_INSERT_ID() on this level. The problem was introduced with the fix of bug 6880, which in turn was introduced with the fix of bug 3117, where current insert_id value was remembered on the first call to LAST_INSERT_ID() (bug 3117) and was returned from that function until it was reset before the next _upper-level_ statement (bug 6880). The fix for bug#21726 brings back the behaviour of version 4.0, and implements the following: remember insert_id value at the beginning of the statement or expression (which at that point equals to the first insert_id value generated by the previous statement), and return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID. Thus, the value returned by LAST_INSERT_ID() is not affected by values generated by current statement, nor by LAST_INSERT_ID(expr) calls in this statement. Version 5.1 does not have this bug (it was fixed by WL 3146). mysql-test/r/rpl_insert_id.result: Add results for bug#21726: Incorrect result with multiple invocations of LAST_INSERT_ID, and bug#20339: stored procedure using LAST_INSERT_ID() does not replicate statement-based. mysql-test/t/rpl_insert_id.test: Add test cases for bug#21726: Incorrect result with multiple invocations of LAST_INSERT_ID, and bug#20339: stored procedure using LAST_INSERT_ID() does not replicate statement-based. sql/item_func.cc: Add implementation of Item_func_last_insert_id::fix_fields(), where we remember in THD::current_insert_id the first value generated during execution of the previous statement, which is returned then from Item_func_last_insert_id::val_int(). sql/item_func.h: Add declaration of Item_func_last_insert_id::fix_fields(). sql/log_event.cc: Do not set THD::last_insert_id_used on LAST_INSERT_ID_EVENT. Though we know the statement will call LAST_INSERT_ID(), it wasn't called yet. sql/set_var.cc: In sys_var_last_insert_id::value_ptr() remember in THD::current_insert_id the first value generated during execution of the previous statement, and return this value for @@LAST_INSERT_ID. sql/sql_class.cc: Reset THD::last_insert_id_used after each statement execution. sql/sql_class.h: Rather then remember current insert_id value on first invocation of THD::insert_id(), remember it in Item_func_last_insert_id::fix_fields(), sys_var_last_insert_id::value_ptr(), or mysql_execute_command(). Remove THD::insert_id(), as it lost its value now. sql/sql_insert.cc: THD::insert_id() is removed, use THD::last_insert_id directly. sql/sql_load.cc: THD::insert_id() is removed, using THD::last_insert_id directly is OK. sql/sql_parse.cc: Remember in THD::current_insert_id first generated insert id value of the previous statement in mysql_execute_command(). No need to reset THD::last_insert_id_used in mysql_reset_thd_for_next_command(), it will be reset after each statement. sql/sql_select.cc: If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value, which is THD::current_insert_id, and also set THD::last_insert_id_used to issue binary log LAST_INSERT_ID_EVENT. sql/sql_update.cc: THD::insert_id() is removed, use THD::last_insert_id directly. tests/mysql_client_test.c: Add test case for bug#21726: Incorrect result with multiple invocations of LAST_INSERT_ID.
