MySQL Bugs: #53452: Inconsistent behavior of binlog_direct_non_transactional

Bug #53452	Inconsistent behavior of binlog_direct_non_transactional_updates with temp table

Status:	Closed	Impact on me:	None
Category:	MySQL Server: Replication	Severity:	S3 (Non-critical)
Version:	5.6.99-m4, 5.5-m3	OS:	Any
Assigned to:	Alfranio Junior	CPU Architecture:	Any

Description:
The manual (http://dev.mysql.com/doc/refman/5.5/en/replication-options-binary-log.html#sysvar_binlog_d...) says that binlog_direct_non_transactional_updates defines whether a statement updating non-transactional tables is written directly in binary log (in statement format), or is cached.
Comment of Apr 30 on bug#53259 says that now temporary tables might behave like transactional tables, regardless their storage engine.

Thus, one could expect that binlog_direct_non_transactional_updates affects statements involving (txn + non-txn) tables and (tmp + non-txn) tables similarly; but it does not.

In 'How to repeat' section, there are 3 test cases.

Case #3 only works with a non-transactional table and is written to binlog right away, regardless binlog_direct_non_transactional_updates (as expected).

Case #2 reads from an InnoDB table and writes into a MyISAM table (the statement produces a warning). When binlog_direct_non_transactional_updates=OFF, the statement is hold off till COMMIT, and when binlog_direct_non_transactional_updates=ON, it is written to the binary log not waiting for commit (as expected).

Case #1 reads from a temporary MyISAM table and writes into a MyISAM table. It could be expected that it either behaves as Case #3 (due to actual engines), or the same way as Case #2 (due to comment on bug#53259 about temporary tables being similar to transactional). However, it does neither -- the statement is always hold off till commit, regardless the binlog_direct_non_transactional_updates value.

Note: fix for bug#51291 recently introduced some limitations in the behaviour related to the variable, but apparently it did not affect the provided test case (as for Case #2 the variable is still working).

How to repeat:
CREATE TABLE t_myisam ( i INT ) ENGINE = MyISAM;
CREATE TEMPORARY TABLE tmp ( i INT ) ENGINE = MyISAM;
CREATE TABLE t_innodb ( i INT ) ENGINE = InnoDB;
INSERT INTO tmp VALUES (1);
INSERT INTO t_innodb VALUES (1);
SET SESSION binlog_direct_non_transactional_updates = ON;

# Case #1

START TRANSACTION;
INSERT INTO t_myisam SELECT * FROM tmp;
# Nothing written into binlog
COMMIT;
# Insert is written into binlog

# Case #2

START TRANSACTION;
INSERT INTO t_myisam SELECT * FROM t_innodb;
# Insert is written to binlog
COMMIT;
# No further changes in binlog

# Case #3

START TRANSACTION;
INSERT INTO t_myisam SELECT * FROM t_myisam;
# Insert is written to binlog
COMMIT;
# No further changes in binlog

Hi Elena,

The bug is in case #2:

START TRANSACTION;
INSERT INTO t_myisam SELECT * FROM t_innodb;
# Insert is written to binlog
COMMIT;
# No further changes in binlog

This was supposed to generate the following entries:

START TRANSACTION;
INSERT INTO t_myisam SELECT * FROM t_innodb;
# Nothing written into binlog
COMMIT;
# Insert is written into binlog

See another example to understand the reason:

-- EXECUTION --:

BEGIN;
INSERT INTO t_innodb VALUES (...);
INSERT INTO t_myisam SELECT * FROM t_innodb;
COMMIT;

-- BINARY LOG --:

BEGIN;
INSERT INTO myisam_t SELECT * FROM innodb_t;
COMMIT;

BEGIN;
INSERT INTO innodb_t VALUES (...);
COMMIT;

This clearly will make the slaves go out of sync.

Cheers.

      BUG#53452 Inconsistent behavior of binlog_direct_non_transactional_updates with temp table
      
      When the binary logging format is STATEMENT, a mixed statement (i.e. a
      statement that accesses nontransactional table as well as transactional
      or temporary table, and writes to any of them) must be written to the
      binary log upon commit the on-going transaction.
      
      Unfortunately, the following statement was not following this rule thus
      making slaves to go out of sync: INSERT INTO myisam_t SELECT * FROM innodb_t.
      
      To fix the problem, we introduced a flag that forces this rule when there
      is a mixed statement.

BUG#53452 Inconsistent behavior of binlog_direct_non_transactional_updates with temp table

This fix improves and clarifies the behavior of the binlog_direct_non_transactional_updates
by writing directly to the binary log any statement that changes a non-transactional table.

Before the patch,

. a mixed statement that updated both a transactional or non-transactional table was kept
in the trx-cache.

. a mixed statment that updated a non-transactional table and read from a temporary table
was kept in the trx-cache if the trx-cache was not empty or the temporary table was
transactional.

otherwise the slave would diverge.

Reorganize the code to make it clear.

BUG#53452 Inconsistent behavior of binlog_direct_non_transactional_updates with temp table

This patch introduces two key changes in the replication's behavior.

Firstly, it reverts part of BUG#51894 which puts any update to temporary tables
into the trx-cache. Now, updates to temporary tables are handled according to
the type of their engines as a regular table.

Secondly, an unsafe mixed statement, (i.e. a statement that access transactional
table as well non-transactional or temporary table, and writes to any of them),
are written into the trx-cache in order to minimize errors in the execution when
the statement logging format is in use.

Such changes has a direct impact on which statements are classified as unsafe
statements and thus part of BUG#53259 is reverted.

BUG#53452 Inconsistent behavior of binlog_direct_non_transactional_updates with temp table

This patch introduces two key changes in the replication's behavior.

Firstly, it reverts part of BUG#51894 which puts any update to temporary tables
into the trx-cache. Now, updates to temporary tables are handled according to
the type of their engines as a regular table.

Secondly, an unsafe mixed statement, (i.e. a statement that access transactional
table as well non-transactional or temporary table, and writes to any of them),
are written into the trx-cache in order to minimize errors in the execution when
the statement logging format is in use.

Such changes has a direct impact on which statements are classified as unsafe
statements and thus part of BUG#53259 is reverted.

      Post-fix push for BUG#53452.
      
      Updated the result files for ndb test cases.

See also BUG#53259.

Documented in the 5.5.6 changelog as follows:

        The value of binlog_direct_non_transactional_updates had no
        effect on statements mixing transactional tables and
        nontransactional tables, or mixing tables and nontransactional
        tables.

        As part of the fix for this issue, updates to temporary tables
        are now handled as transactional or nontransactional according
        to their storage engine types. (In effect, the current fix
        reverts a change made previously as part of the fix for
        Bug#53259.) In addition, unsafe mixed statements (that is, 
        statements which access transactional table as well as 
        nontransactional or temporary tables, and write to any of them) 
        are now handled as transactional when the statement-based logging 
        format is in use.

Also updated relevant portions of 5.5/5.6 Manuals.
