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;
optimization to set the flag at the end of per-row loop;
multi-delete still has an extra issue similar to bug#27716 of multi-update
- to be address with bug_29136 fix.
sql/sql_insert.cc:
thd->transaction.{all,stmt}.modified_non_trans_table
instead of
thd->no_trans_update.{all,stmt}
sql/sql_load.cc:
eliminating a separate issue where the stmt flag was saved and re-stored after
write_record that actually could change it and the change would be lost but
should remain permanent;
thd->transaction.{all,stmt}.modified_non_trans_table
instead of
thd->no_trans_update.{all,stmt}
sql/sql_parse.cc:
initialization to transaction.stmt.modified_non_trans_table at the common part
of all types of statements processing - mysql_execute_command().
sql/sql_table.cc:
moving the reset up to the mysql_execute_command() caller
sql/sql_update.cc:
correcting update query case (multi-update part of the issues covered by other
bug#27716 fix)
thd->transaction.{all,stmt}.modified_non_trans_table
instead of
thd->no_trans_update.{all,stmt}
