mysql-test/suite/rpl/t/rpl_000011-slave.opt:
Renamed test case as it's slave that needs to restarted
support-files/compiler_warnings.supp:
Fixed bad characters in suppression
mysql-test/suite/rpl/t/rpl_000011-master.opt:

plugin/server_audit/server_audit.c:
Fixed compiler error on solaris
support-files/compiler_warnings.supp:
Ignore warning from xtradb
Reason for the bug was an optimization for higher connect speed where we moved when global status was updated,
but forgot to update states when slave thread dies.
Fixed by adding thd->add_status_to_global() before deleting slave thread's thd.
mysys/my_delete.c:
Added missing newline
sql/mysqld.cc:
Use add_status_to_global()
sql/slave.cc:
Added missing add_status_to_global()
sql/sql_class.cc:

sql/sql_class.h:
Simplify adding local status to global by adding add_status_to_global()

Enable rpl_row_create_table (no reason to keep this disabled anymore)
Still fails (in --ps), no reason to enable it if it is not fixed.
This worklog aims at testing the two following scenarios:
1) Whenever the mysql_binlog_send method (dump thread)
reaches the end of file when reading events from the binlog, before
checking if it should wait for more events, there was a test to
check if the file being read was still active, i.e, it was the last
known binlog. However, it was possible that something was written to
the binary log and then a rotation would happen, after EOF was
detected and before the check for active was performed. In this
case, the end of the binary log would not be read by the dump
thread, and this would cause the slave to lose updates.
This test verifies that the problem has been fixed. It waits during
this window while forcing a rotation in the binlog.
2) Verify dump thread can send events in active file, correctly after
encountering an IO error.

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.

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`;'.

Remove warning
MDEV-4489 "Replication of big5, cp932, gbk, sjis strings makes wrong values on slave"
has been fixed.
Problem:
String constants of some Asian charsets (big5,cp932,gbk,sjis)
can have backslash '\' (0x5C) in the second byte of multi-byte characters.
Replicating of such constants using the standard '\'-escaping is dangerous.
Therefore, constants of these charsets are replicated using hex notation:
INSERT INTO t1 (a) VALUES (0x815C);
However, 0xHHHH constants do not work well in some cases,
because they can behave as strings and as numbers, depending on context
(for example, depending on the data type of the column in an INSERT statement).
This SQL script was not replicated correctly with statement-based replication:
SET NAMES gbk;
PREPARE STMT FROM 'INSERT INTO t1 (a) VALUES (?)';
SET @a = '1';
EXECUTE STMT USING @a;
The INSERT statement was replicated as:
INSERT INTO t1 (a) VALUES (0x31);
'1' was correctly converted to the number 1 on master.
But the 0x31 constant was treated as number 49 on slave.
Fix:
1. Binary log now uses X'HHHH' instead of 0xHHHH constants.
2. The X'HHHH' constants now work always as strings, in all contexts.
This is the SQL standard compliant behaviour.
After the fix, the above statement is replicated as:
INSERT INTO t1 (a) VALUES (X'31');
X'31' is treated as string '1' on slave, and is correctly converted to 1.

--BINLOG-IGNORE-DB AND FULLY QUALIFIED TABLE
Problem:
=======
An ALTER TABLE statement is not written to binlog if server
started with "--binlog-ignore-db some database" and 'fully
qualified' table names are used in the ALTER TABLE statement
altering table different from current database context.
Analysis:
========
The above mentioned problem not only affects "ALTER TABLE"
statements but also to all kind of statements. Once the
current default database becomes "NULL" none of the
statements will be binlogged.
The current behaviour is such that if the user has specified
restrictions on which database needs to be replicated and the
default db is not specified, then do not replicate.
This means that "NULL" is considered to be equivalent to
everything (default db = null implied ignore don't log the
statement).
Fix:
===
"NULL" should not be considered as equivalent to everything.
Since the filtering criteria is not equal to "NULL" the
statement should be logged into binlog.
mysql-test/suite/rpl/r/rpl_loaddata_m.result:
Earlier when defalut database was "NULL" DROP TABLE
was not getting logged. Post this fix it will be logged
and the DROP will fail at slave as the table creation
was skipped by master as --binlog-ignore-db=test.

PLATFORM= MACOSX10.6 X86_64 MAX
Problem: The test was failing on pb2's mac machine because
it was not cleaned up properly. The test checks if
the command 'start slave until' throws a proper
error when issued with a wrong number/type of
parameters. After this,the replication stream was
stopped using the include file 'rpl_end.inc'.
The errors thrown earlier left the slave in an
inconsistent state to be closed by the include
file which was caught by the mac machine.
Fix: Started slave by invoking start_slave.inc to have a
working slave before calling rpl_reset.inc
Problem: The test file was not in a good shape. It tested
start slave until relay log file/pos combination
wrongly. A couple of commands were executed at
master and replicated at slave. Next, the
coordinates in terms of relay log file and pos
were noted down followed by reset slave and start
slave until saved relay log file/pos. Reset slave
deletes all relay log files and makes the slave
forget its replication position. So, using the
saved coordiantes after reset slave is wrong.
Fix: Split the test in two parts:
a) Test for start slave until master log file/pos and
checking for correct errors in the failure
scenarios.
b) Test for start slave until relay log file/pos.
Problem: The variables auto_increment_increment and
auto_increment_offset were set in the the include
file rpl_init.inc. This was only configured for
some connections that are rarely used by test
cases, so likely that it will cause confusion.
If replication tests want to setup these variables
they should do so explicitly.
Fix:
a) Removed code to set the variables
auto_increment_increment and auto_increment_offset
in the include file.
b) Updated tests files using the same.

DOWNGRADED FROM 5.6.11 TO 5.6.10
Problem was new syntax not accepted by previous version.
Fixed by adding version comment of /*!50531 around the
new syntax.
Like this in the .frm file:
'PARTITION BY KEY /*!50611 ALGORITHM = 2 */ () PARTITIONS 3'
and also changing the output from SHOW CREATE TABLE to:
CREATE TABLE t1 (a INT)
/*!50100 PARTITION BY KEY */ /*!50611 ALGORITHM = 1 */ /*!50100 ()
PARTITIONS 3 */
It will always add the ALGORITHM into the .frm for KEY [sub]partitioned
tables, but for SHOW CREATE TABLE it will only add it in case it is the non
default ALGORITHM = 1.
Also notice that for 5.5, it will say /*!50531 instead of /*!50611, which
will make upgrade from 5.5 > 5.5.31 to 5.6 < 5.6.11 fail!
If one downgrades an fixed version to the same major version (5.5 or 5.6) the
bug 14521864 will be visible again, but unless the .frm is updated, it will
work again when upgrading again.
Also fixed so that the .frm does not get updated version
if a single partition check passes.
