b2b07b33cf Don't write DROP TEMPORARY TABLE to binary log
if we didn't write the CREATE TEMPORARY TABLE statement.

- Enable old code from one of my older changesets that didn't make into 10.0
- Fix test cased that failed as they expected DROP TEMPORARY TABLE in the log.

5da083ef67 Bug#20041860: SLAVE ERROR WHEN DROP DATABASE
Fix:
===
Backport Bug#11756194 to mysql-5.5. slave breaks if
'drop database' fails on master and mismatched tables on
slave.

'DROP TABLE <deleted tables>' was binlogged when
'DROP DATABASE' failed and at least one table was deleted
from the database. The log event would lead slave SQL thread
stop if some of the tables did not exist on slave.

After this patch, It is always binlogged with 'IF EXISTS'
option.

eb152f86af BUG#16290902 DROP TEMP TABLE IF EXISTS CAN CAUSE POINT
IN TIME RECOVERY FAILURE ON SLAVES

Problem:
DROP TEMP TABLE IF EXISTS commands can cause point
in time recovery (re-applying binlog) failures.

Analyses:
In RBR, 'DROP TEMPORARY TABLE' commands are
always binlogged by adding 'IF EXISTS' clauses.
Also, the slave SQL thread will not check replicate.* filter
rules for "DROP TEMPORARY TABLE IF EXISTS" queries.
If log-slave-updates is enabled on slave, these queries
will be binlogged in the format of "USE `db`;
DROP TEMPORARY TABLE IF EXISTS `t1`;" irrespective
of filtering rules and irrespective of the `db` existence.
When users try to recover slave from it's own binlog,
use `db` command might fail if `db` is not present on slave.

Fix:
At the time of writing the 'DROP TEMPORARY TABLE
IF EXISTS' query into the binlog, 'use `db`' will not be
present and the table name in the query will be a fully
qualified table name.
Eg:
'USE `db`; DROP TEMPORARY TABLE IF EXISTS `t1`;'
will be logged as
'DROP TEMPORARY TABLE IF EXISTS `db`.`t1`;'.

d9f975d08b MDEV-26: Global transaction ID
Adjust full test suite to work with GTID.

Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.

Everything was painstakingly checked to be still correct and valid .result
file updates.

and small collateral changes

mysql-test/lib/My/Test.pm:
  somehow with "print" we get truncated writes sometimes
mysql-test/suite/perfschema/r/digest_table_full.result:
  md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/dml_handler.result:
  host table is not ported over yet
mysql-test/suite/perfschema/r/information_schema.result:
  host table is not ported over yet
mysql-test/suite/perfschema/r/nesting.result:
  this differs, because we don't rewrite general log queries, and multi-statement
  packets are logged as a one entry. this result file is identical to what mysql-5.6.5
  produces with the --log-raw option.
mysql-test/suite/perfschema/r/relaylog.result:
  MariaDB modifies the binlog index file directly, while MySQL 5.6 has a feature "crash-safe binlog index" and modifies a special "crash-safe" shadow copy of the index file and then moves it over. That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB.
mysql-test/suite/perfschema/r/server_init.result:
  MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup.
mysql-test/suite/perfschema/r/stage_mdl_global.result:
  this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not
  do that, and this causes useless mutex locks and waits.
mysql-test/suite/perfschema/r/statement_digest.result:
  md5 hashes of statement digests differ, because yacc token codes are different in mariadb

f94e7288e3 Bug (former 58381)
FAILED DROP DATABASE CAN BREAK STATEMENT BASED REPLICATION

The first phase of DROP DATABASE is to delete the tables in the database.
If deletion of one or more of the tables fail (e.g. due to a FOREIGN KEY
constraint), DROP DATABASE will be aborted. However, some tables could
still have been deleted. The problem was that nothing would be written
to the binary log in this case, so any slaves would not delete these tables.
Therefore the master and the slaves would get out of sync.

This patch fixes the problem by making sure that DROP TABLE is written
to the binary log for the tables that were in fact deleted by the failed
DROP DATABASE statement.

Test case added to binlog.binlog_database.test.

ac6026ce27 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.

20f5c421e7 BUG#51894 Replication failure with SBR on DROP TEMPORARY TABLE inside a
transaction
BUG#52616 Temp table prevents switch binlog format from STATEMENT to ROW

Before the WL#2687 and BUG#46364, every non-transactional change that happened
after a transactional change was written to trx-cache and flushed upon
committing the transaction. WL#2687 and BUG#46364 changed this behavior and
non-transactional changes are now written to the binary log upon committing
the statement.

A binary log event is identified as transactional or non-transactional through
a flag in the Log_event which is set taking into account the underlie storage
engine on what it is stems from. In the current bug, this flag was not being
set properly when the DROP TEMPORARY TABLE was executed.

However, while fixing this bug we figured out that changes to temporary tables
should be always written to the trx-cache if there is an on-going transaction.
Otherwise, binlog events in the reversed order would be produced.

Regarding concurrency, keeping changes to temporary tables in the trx-cache is
also safe as temporary tables are only visible to the owner connection.

In this patch, we classify the following statements as unsafe:
   1 - INSERT INTO t_myisam SELECT * FROM t_myisam_temp

   2 - INSERT INTO t_myisam_temp SELECT * FROM t_myisam

   3 - CREATE TEMPORARY TABLE t_myisam_temp SELECT * FROM t_myisam

On the other hand, the following statements are classified as safe:

   1 - INSERT INTO t_innodb SELECT * FROM t_myisam_temp

   2 - INSERT INTO t_myisam_temp SELECT * FROM t_innodb

The patch also guarantees that transactions that have a DROP TEMPORARY are
always written to the binary log regardless of the mode and the outcome:
commit or rollback. In particular, the DROP TEMPORARY is extended with the
IF EXISTS clause when the current statement logging format is set to row.

Finally, the patch allows to switch from STATEMENT to MIXED/ROW when there
are temporary tables but the contrary is not possible.

  Fixed the case that a DROP/DROP TEMPORARY that affects a temporary table in MIXED
  mode is written as a DROP TEMPORARY TABLE IF EXISTS because the table may not exist in the slave and due to the IF EXISTS token an error will never happen
  while processing the statement in the slave.
  
  Removed a function that was not being used.

9ba731c299 BUG#51894 Replication failure with SBR on DROP TEMPORARY TABLE inside a
transaction
BUG#52616 Temp table prevents switch binlog format from STATEMENT to ROW

Before the WL#2687 and BUG#46364, every non-transactional change that happened
after a transactional change was written to trx-cache and flushed upon
committing the transaction. WL#2687 and BUG#46364 changed this behavior and
non-transactional changes are now written to the binary log upon committing
the statement.

A binary log event is identified as transactional or non-transactional through
a flag in the Log_event which is set taking into account the underlie storage
engine on what it is stems from. In the current bug, this flag was not being
set properly when the DROP TEMPORARY TABLE was executed.

However, while fixing this bug we figured out that changes to temporary tables
should be always written to the trx-cache if there is an on-going transaction.
Otherwise, binlog events in the reversed order would be produced.

Regarding concurrency, keeping changes to temporary tables in the trx-cache is
also safe as temporary tables are only visible to the owner connection.

In this patch, we classify the following statements as unsafe:
   1 - INSERT INTO t_myisam SELECT * FROM t_myisam_temp

   2 - INSERT INTO t_myisam_temp SELECT * FROM t_myisam

   3 - CREATE TEMPORARY TABLE t_myisam_temp SELECT * FROM t_myisam

On the other hand, the following statements are classified as safe:

   1 - INSERT INTO t_innodb SELECT * FROM t_myisam_temp

   2 - INSERT INTO t_myisam_temp SELECT * FROM t_innodb

The patch also guarantees that transactions that have a DROP TEMPORARY are
always written to the binary log regardless of the mode and the outcome:
commit or rollback. In particular, the DROP TEMPORARY is extended with the
IF EXISTS clause when the current statement logging format is set to row.

Finally, the patch allows to switch from STATEMENT to MIXED/ROW when there
are temporary tables but the contrary is not possible.

19c380aaff WL#2687 WL#5072 BUG#40278 BUG#47175
Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.

In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.

0203409175 Bug : DROP DATABASE cause switch to stmt-mode when there are temporary
tables open

When executing a DROP DATABASE statement in ROW mode and having temporary
tables open at the same time, the existance of temporary tables prevent
the server from switching back to row mode after temporarily switching to
statement mode to handle the logging of the statement.

Fixed the problem by removing the code to switch to statement mode and added
code to temporarily disable the binary log while dropping the objects in the
database.
