error code
Problem:
========
CURRENT_TEST: binlog_encryption.rpl_corruption
mysqltest: In included file "./include/wait_for_slave_io_error.inc":
...
At line 72: Slave stopped with wrong error code
**** Slave stopped with wrong error code: 1743 (expected 1595,1913) ****
Analysis:
========
The test emulates the corruption at the various stages of replication for
example in binlog file, in network and in relay log etc. It verifies that all
corruption cases are handled through appropriate error messages.
The test cases which emulate network failure expect following errors.
--ER_SLAVE_RELAY_LOG_WRITE_FAILURE (1595)
--ER_NETWORK_READ_EVENT_CHECKSUM_FAILURE (1743)
Ideally test should expect error codes as 1595 and 1743.
But the test actually waits on incorrect error code 1595,1913
Fix:
===
Added appropriate error code for 'ER_NETWORK_READ_EVENT_CHECKSUM_FAILURE'.
Replaced 1913 with 1743.

MDEV-5589 commit set up a policy to skip DROP TEMPORARY TABLE binary logging
in case the target table has not been "CREATEed" in binlog (no CREATE
Query-log-event was logged into the binary log).
It turns out that
1. the rule did not cover non-existing table DROPped with IF-EXISTS clause.
The logged-create knowledge for the non-existing one does not even need
MDEV-5589 patch, and
2. connection close disobeys it to trigger automatic DROP-IF-EXISTS
binlogging.
Either 1 or 2 or even both is/are also responsible for unexpected binlog
records observed in MDEV-17863, actually rendering a referred
@@global.read_only irrelevant as far as the described stored procedure
definition *and* the ROW binlog-format are concerned.

Analysis:
=========
Enabling "replicate_annotate_row_events" on slave, Tells the slave to write
annotate rows events received from the master to its own binary log. The
received annotate events are applied after the Gtid event as shown below.
thd->query() will be set to the actual query received from the master, through
annotate event. Annotate_rows event should not be deleted after the event is
applied as the thd->query will be used to generate new Annotate_rows event
during applying the subsequent Rows events. After the last Rows event has been
applied, the saved Annotate_rows event (if any) will be deleted.
In balckhole engine all the DML operations are noops as they donot store any
data. They simply return success without doing any operation. But the existing
strictly expects thd->query() to be 'NULL' to identify that row based
replication is in use. This assumption will fail when row annotations are
enabled as the query is not 'NULL'. Hence various row based operations like
'update', 'delete', 'index lookup' will fail when row annotations are enabled.
Fix:
===
Extend the row based replication check to include row annotations as well.
i.e Either the thd->query() is NULL or thd->query() points to query and row
annotations are in use.

Problem was that Binlog_checkpoint can happen at random times.
Fixed by not write binlog_checkpoint for the rpl_log test.
Other things:
- Removed not used variable "$keep_gtid_events"
- Added option for show_binlog_events to skip binlog_checkpoint

The race condition happened if mark_xid_done was considerably delayed,
and an extra Binlog_checkpoint event was written into the binary log
which was later indicated in an error message. Fixed by ensuring
that the event is written before the binary log is rotated to the one
which is used in the output.

- created binlog_encryption test suite and added it to the default list
- moved some tests from rpl, binlog and multisource suites to extra

The problem was that wait_for_slave_io_to_start reported that the io thread
was ready, when it was still initializing. This caused test suite to
continue too early, for example before the semi sync plugin was properly
enabled.
Fixed by introducing a new internal stage: "Preparing". Slave_IO_Running is
now set to "Yes" only when all initializing is done and the IO thread is
ready to read things from the master.
The only test affected by this change is rpl_flsh_tbls, which got stuck in
the preparing phase while trying to read the GTID position from a table.
Fixed by having this test waiting for Preparing instead of Yes.

The slave SQL thread was clearing serial_rgi->thd before deleting
serial_rgi, which could cause access to NULL THD.
The clearing was introduced in commit
2e100cc5a493b6a0f6f907e0483a734c7fee2087 and is just plain wrong. So revert
that part (single line) of that commit.
Thanks to Daniel Black for bug analysis and test case.

message:
BUG#13627921 - MISSING FLAGS IN SQL_COMMAND_FLAGS MAY LEAD TO REPLICATION PROBLEMS
Flags in sql_command_flags[command] are not correctly set for the following
commands:
. SQLCOM_SET_OPTION is missing CF_CAN_GENERATE_ROW_EVENTS;
. SQLCOM_BINLOG_BASE64_EVENT is missing CF_CAN_GENERATE_ROW_EVENTS;
. SQLCOM_REVOKE_ALL is missing CF_CHANGES_DATA;
. SQLCOM_CREATE_FUNCTION is missing CF_AUTO_COMMIT_TRANS;
This may lead to a wrong sequence of events in the binary log. To fix
the problem, we correctly set the flags in sql_command_flags[command].

- CREATE TABLE is by default executed on the slave as CREATE OR REPLACE
- DROP TABLE is by default executed on the slave as DROP TABLE IF NOT EXISTS
This means that a slave will by default continue even if we try to create
a table that existed on the slave (the table will be deleted and re-created) or
if we try to drop a table that didn't exist on the slave.
This should be safe as instead of having the slave stop because of an inconsistency between
master and slave, it will fix the inconsistency.
Those that would prefer to get a stopped slave instead for the above cases can set slave_ddl_exec_mode to STRICT.
- Ensure that a CREATE OR REPLACE TABLE which dropped a table is replicated
- DROP TABLE that generated an error on master is handled as an identical DROP TABLE on the slave (IF NOT EXISTS is not added in this case)
- Added slave_ddl_exec_mode variable to decide how DDL's are replicated
New logic for handling BEGIN GTID ... COMMIT from the binary log:
- When we find a BEGIN GTID, we start a transaction and set OPTION_GTID_BEGIN
- When we find COMMIT, we reset OPTION_GTID_BEGIN and execute the normal COMMIT code.
- While OPTION_GTID_BEGIN is set:
- We don't generate implict commits before or after statements
- All tables are regarded as transactional tables in the binary log (to ensure things are executed exactly as on the master)
- We reset OPTION_GTID_BEGIN also on rollback
This will help ensuring that we don't get any sporadic commits (and thus new GTID's) on the slave and will help keep the GTID's between master and slave in sync.

DURING INNODB RECOVERY
Problem:
=======
The connection 'master' is dropped by mysqltest after
rpl_end.inc. At this point, dropping temporary tables
at the connection 'master' are not synced at slave.
So, the temporary tables replicated from master remain
on slave leading to an inconsistent close of the test.
The following test thus complains about the presence of
temporary table(s) left over from the previous test.
Fix:
===
- Put explicit drop commands in replication tests so
that the temporary tables are dropped at slave as well.
- Added the check for Slave_open_temp_tables in
mtr_check.sql to warn about the remaining temporary
table, if any, at the close of a test.
