From 1307d3b8033985d842b900ec8ebe7be9f0a4e092 Mon Sep 17 00:00:00 2001 From: unknown Date: Mon, 30 Jul 2007 18:27:36 +0300 Subject: (pushing for Andrei) Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack Once had been set the flag might later got reset inside of a stored routine execution stack. The reason was in that there was no check if a new statement started at time of resetting. The artifact affects most of binlogable DML queries. Notice, that multi-update is wrapped up within bug@27716 fix, multi-delete bug@29136. Fixed with saving parent's statement flag of whether the statement modified non-transactional table, and unioning (merging) the value with that was gained in mysql_execute_command. Resettling thd->no_trans_update members into thd->transaction.`member`; Asserting code; Effectively the following properties are held. 1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table reflects the fact if such a table got modified by the substatement. That also respects THD::really_abort_on_warnin() requirements. 2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as the union of the values of all invoked sub-statements. That fixes this bug#27417; Computing of thd->transaction.all.modified_non_trans_table is refined to base to the stmt's value for all the case including insert .. select statement which before the patch had an extra issue bug@28960. Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in to temp_table select. The supplied test verifies limitely, mostly asserts. The ultimate testing is defered for bug@13270, bug@23333. mysql-test/r/mix_innodb_myisam_binlog.result: results changed mysql-test/t/mix_innodb_myisam_binlog.test: regression test incl the related bug#28960. sql/ha_ndbcluster.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/handler.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/handler.h: new member added sql/log.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/set_var.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sp_head.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} and saving and merging stmt's flag at the end of a substatement. sql/sql_class.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sql_class.h: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sql_delete.cc: correcting basic delete incl truncate branch and multi-delete queries to set stmt.modified_non_trans_table;
