THOUGH IT IS NOT.
The following error message is misleading because it claims
that the BLOB space is not counted.
"ERROR 1118 (42000): Row size too large. The maximum row size for
the used table type, not counting BLOBs, is 8126. You have to
change some columns to TEXT or BLOBs"
When the ROW_FORMAT=compact or ROW_FORMAT=REDUNDANT is used,
the BLOB prefix is stored inline along with the row. So
the above error message is changed as follows depending on
the row format used:
For ROW_FORMAT=COMPRESSED or ROW_FORMAT=DYNAMIC, the error
message is as follows:
"ERROR 42000: Row size too large (> 8126). Changing some
columns to TEXT or BLOB may help. In current row format,
BLOB prefix of 0 bytes is stored inline."
For ROW_FORMAT=COMPACT or ROW_FORMAT=REDUNDANT, the error
message is as follows:
"ERROR 42000: Row size too large (> 8126). Changing some
columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or
ROW_FORMAT=COMPRESSED may help. In current row
format, BLOB prefix of 768 bytes is stored inline."

NUMBERS
If a system variable was declared as deprecated without mention of an
alternative, the message would look funny, e.g. for @@delayed_insert_limit:
Warning 1287 '@@delayed_insert_limit' is deprecated and
will be removed in MySQL .
The message was meant to display the version number, but it's not
possible to give one when declaring a system variable.
The fix does two things:
1) The definition of the message
ER_WARN_DEPRECATED_SYNTAX_NO_REPLACEMENT is changed so that it does
not display a version number. I.e. in English the message now reads:
Warning 1287 The syntax '@@delayed_insert_limit' is deprecated and
will be removed in a future version.
2) The message ER_WARN_DEPRECATED_SYNTAX_WITH_VER is discontinued in
favor of ER_WARN_DEPRECATED_SYNTAX for system variables. This change
was already done in versions 5.6 and above as part of wl#5265. This
part is simply back-ported from the worklog.
WARNING
This patch is for mysql-5.5 only,
to be null-merged to mysql-5.6 and mysql-trunk.
This is a partial rollback of the file io instrumentation,
removing the instrumentation for mysql_file_stat in the archive engine.
See the bug comments for details.

It's safe to remove the call in this case as we will call HA_EXTRA_PREPARE_FOR_DROP for the table anyway.
(One nice side effect is that drop is a bit faster as we are not flushing the cache to disk before the drop anymore)
Starting the SQL thread might deadlock with reading the values of the
replication filtering options.
The deadlock is due to a lock order violation when the variables are
read or set. For example, reading replicate_ignore_table first
acquires LOCK_global_system_variables in sys_var::value_ptr and later
acquires LOCK_active_mi in Sys_var_rpl_filter::global_value_ptr. This
violates the order established when starting a SQL thread, where
LOCK_active_mi is acquired before start_slave, and ends up creating a
thread (handle_slave_sql) that allocates a THD handle whose
constructor acquires LOCK_global_system_variables in THD::init.
The solution is to unlock LOCK_global_system_variables before the
replication filtering options are set or read. This way the lock
order is preserved and the data being read/set is still protected
given that it acquires LOCK_active_mi.

Problem description:
Table 't' created with two colums having compound index on both the
columns under innodb/myisam engine at remote machine. In the local
machine same table is created undet the federated engine.
A select having where clause with along 'AND' operation gives wrong
results on local machine.
Analysis:
The given query at federated engine is wrongly transformed by
federated::create_where_from_key() function and the same was sent to
the remote machine. Hence the local machine is showing wrong results.
Given query "select c1 from t where c1 <= 2 and c2 = 1;"
Query transformed, after ha_federated::create_where_from_key() function is:
SELECT `c1`, `c2` FROM `t` WHERE (`c1` IS NOT NULL ) AND
( (`c1` >= 2) AND (`c2` <= 1) ) and the same sent to real_query().
In the above the '<=' and '=' conditions were transformed to '>=' and
'<=' respectively.
ha_federated::create_where_from_key() function behaving as below:
The key_range is having both the start_key and end_key. The start_key
is used to get "(`c1` IS NOT NULL )" part of the where clause, this
transformation is correct. The end_key is used to get "( (`c1` >= 2)
AND (`c2` <= 1) )", which is wrong, here the given conditions('<=' and '=')
are changed as wrong conditions('>=' and '<=').
The end_key is having {key = 0x39fa6d0 "", length = 10, keypart_map = 3,
flag = HA_READ_AFTER_KEY}
The store_length is having value '5'. Based on store_length and length
values the condition values is applied in HA_READ_AFTER_KEY switch case.
The switch case 'HA_READ_AFTER_KEY' is applicable to only the last part of
the end_key and for previous parts it is going to 'HA_READ_KEY_OR_NEXT' case,
here the '>=' is getting added as a condition instead of '<='.
Fix:
Updated the 'if' condition in 'HA_READ_AFTER_KEY' case to affect for all
parts of the end_key. i.e 'i > 0' will used for end_key, Hence added it in
the if condition.

Now when a table is dropped the statistics on the table is removed
from the statistical tables. If the table is altered in such a way
that a column is dropped or the type of the column is changed then
statistics on the column is removed from the table column_stat.
It also triggers removal of the statistics on the indexes who use
this column as its component.
Added procedures that changes the names of the tables or columns
in the statistical tables for.
These procedures are used when tables/columns are renamed.
Also partly re-factored the code that introduced the persistent
statistical tables.
Added test cases into statistics.test to cover the new code.

Keep track of how many pending XIDs (transactions that are prepared in
storage engine and written into binlog, but not yet durably committed
on disk in the engine) there are in each binlog.
When the count of one binlog drops to zero, write a new binlog checkpoint
event, telling which is the oldest binlog with pending XIDs.
When doing XA recovery after a crash, check the last binlog checkpoint
event, and scan all binlog files from that point onwards for XIDs that
must be committed if found in prepared state inside engine.
Remove the code in binlog rotation that waits for all prepared XIDs to
be committed before writing a new binlog file (this is no longer necessary
when recovery can scan multiple binlog files).
Add function to replace arbitrary event with dummy event.
Add code which uses this to fix the bug that enabling row_annotate events
on the master breaks slaves which do not request such events.
Add that slaves set a variable @mariadb_slave_capability to inform the
master in a robust way about which events it can, and cannot, handle.
Add tests.
the new file is fully synced to disk and binlog index. This fixes a window
where a crash would leave next server restart unable to detect that a crash
occured, causing recovery to fail.
The semisync code does a fast-but-unsafe check for enabled or not without lock,
followed by a slow-but-safe check under lock. However, if the slow check failed,
the code still referenced not valid data (in an assert() expression), causing a
crash.
Fixed by not running the incorrect assert when semisync is disabled.
Virtual columns of ENUM and SET data types were not supported properly
in the original patch that introduced virtual columns into MariaDB 5.2.
The problem was that for any virtual column the patch used the
interval_id field of the definition of the column in the frm file as
a reference to the virtual column expression.
The fix stores the optional interval_id of the virtual column in the
extended header of the virtual column expression.

Problem
========
Replication breaks in the cases if the event length exceeds
the size of master Dump thread's max_allowed_packet.
The reason why this failure is occuring is because the event length is
more than the total size of the max_allowed_packet, on addition of the
max_event_header length exceeds the max_allowed_packet of the DUMP thread.
This causes the Dump thread to break replication and throw an error.
That can happen e.g with row-based replication in Update_rows event.
Fix
====
The problem is fixed in 2 steps:
1.) The Dump thread limit to read event is increased to the upper limit
i.e. Dump thread reads whatever gets logged in the binary log.
2.) On the slave side we increase the the max_allowed_packet for the
slave's threads (IO/SQL) by increasing it to 1GB.
This is done using the new server option (slave_max_allowed_packet)
included, is used to regulate the max_allowed_packet of the
slave thread (IO/SQL) by the DBA, and facilitates the sending of
large packets from the master to the slave.
This causes the large packets to be received by the slave and apply
it successfully.
sql/log_event.cc:
The max_allowed_packet is not evaluated to the new option
slave_max_allowed_packet after the fix.
sql/log_event.h:
Added the new option in the log_event.h file.
sql/mysqld.cc:
Added a new option to the server.
sql/slave.cc:
Increasing the session max_allowed_packet to a large value,
i.e. not taking global(max_allowed) into consideration, for the slave's threads.
sql/sql_repl.cc:
The dump thread's max_allowed_packet is set to the upper limit
which makes it independent and it now reads whatever gets
logged in the binary log.
Renamed the system variable optimizer_use_stat_tables to use_stat_tables.
This variable now has only 3 possible values:
'never', 'complementary', 'preferably'.
If the server has been launched with
--use-stat-tables='complementary'|'preferably'
then the statictics tables can be employed by the optimizer and by the
ANALYZE command.

updating the result file. Because a multi-row insert now reserves the
auto increment values before hand, if any explicitly specified auto
increment values are there, then some of the reserved values are lost.
Problem
========
SQL statements close to the size of max_allowed_packet produce binary
log events larger than max_allowed_packet.
The reason why this failure is occuring is because the event length is
more than the total size of the max_allowed_packet + max_event_header
length. Now since the event length exceeds this size master Dump
thread is unable to send the packet on to the slave.
That can happen e.g with row-based replication in Update_rows event.
Fix
====
The problem was fixed by increasing the max_allowed_packet for the
slave's threads (IO/SQL) by increasing it to 1GB.
This is done using the new server option included which is used to
regulate the max_allowed_packet of the slave thread (IO/SQL).
This causes the large packets to be received by the slave and apply
it successfully.
sql/log_event.h:
Added the new option in the log_event.h file.
sql/mysqld.cc:
Added a new option to the server.

Fix is done by doing an autocommit in truncate table inside Aria
storage/maria/ha_maria.cc:
Force a commit for TRUNCATE TABLE inside lock tables
Check that we don't call TRUNCATE with concurrent inserts going on.
Make ha_maria::implict_commit faster when we don't have Aria tables in the transaction.
(Most of the patch is just re-indentation because I removed an if level)
The patch enables back constant subquery execution during
query optimization after it was disabled during the development
of MWL#89 (cost-based choice of IN-TO-EXISTS vs MATERIALIZATION).
The main idea is that constant subqueries are allowed to be executed
during optimization if their execution is not expensive.
The approach is as follows:
- Constant subqueries are recursively optimized in the beginning of
JOIN::optimize of the outer query. This is done by the new method
JOIN::optimize_constant_subqueries(). This is done so that the cost
of executing these queries can be estimated.
- Optimization of the outer query proceeds normally. During this phase
the optimizer may request execution of non-expensive constant subqueries.
Each place where the optimizer may potentially execute an expensive
expression is guarded with the predicate Item::is_expensive().
- The implementation of Item_subselect::is_expensive has been extended
to use the number of examined rows (estimated by the optimizer) as a
way to determine whether the subquery is expensive or not.
- The new system variable "expensive_subquery_limit" controls how many
examined rows are considered to be not expensive. The default is 100.
In addition, multiple changes were needed to make this solution work
in the light of the changes made by MWL#89. These changes were needed
to fix various crashes and wrong results, and legacy bugs discovered
during development.
The optimizer chose a less efficient execution plan due to the following
defects of the code:
1. the generic handler function handler::keyread_time did not take into account
that in clustered primary keys record data is included into each index entry
2. the function make_join_readinfo erroneously decided that index only scan
could not be used if join cache was empoyed.
Added no additional test case.
Adjusted some of the test results.

BY A CONCURRENT TRANSACTIO
The member function QUICK_RANGE_SELECT::init_ror_merged_scan() performs
a table handler clone. Innodb does not provide a clone operation.
The ha_innobase::clone() is not there. The handler::clone() does not
take care of the ha_innobase->prebuilt->select_lock_type. Because of
this what happens is that for one index we do a locking read, and
for the other index we were doing a non-locking (consistent) read.
The patch introduces ha_innobase::clone() member function.
It is implemented similar to ha_myisam::clone(). It calls the
base class handler::clone() and then does any additional operation
required. I am setting the ha_innobase->prebuilt->select_lock_type
correctly.

Problem - The failure on PB2 is possbily due to the port number being still in
use even after the server restarts which is not reflected in the
server restart.
Fix - The problem is fixed by starting the servers forcefully using the option

The function mysql_show_binlog_events has a local stack variable

The problem is solved by moving 'LOG_INFO linfo;' to function scope.
BUG#11761686 insert_id event is not filtered.
Two issues are covered.
INSERT into autoincrement field which is not the first part in the composed primary key
is unsafe by autoincrement logging design. The case is specific to MyISAM engine
because Innodb does not allow such table definition.
However no warnings and row-format logging in the MIXED mode was done, and
that is fixed.
Int-, Rand-, User-var log-events were not filtered along with their parent
query that made possible them to screw up execution context of the following
query.
Fixed with deferring their execution until the parent query.

Currently SHOW MASTER LOGS and SHOW BINARY LOGS require the SUPER
privilege. Monitoring tools (such as MEM) often want to check this
output - for instance MEM generates the SUM of the sizes of the logs
reported here, and puts that in the Replication overview within the MEM
Dashboard.
However, because of the SUPER requirement, these tools often have an
account that holds open the connection whilst monitoring, and can lock
out administrators when the server gets overloaded and reaches
max_connections - there is already another SUPER privileged account
connected, the "monitor".
As SHOW MASTER STATUS, and all other replication related statements,
return with either REPLICATION CLIENT or SUPER privileges, this worklog
is to make SHOW MASTER LOGS and SHOW BINARY LOGS be consistent with this
as well, and allow both of these commands with either SUPER or
REPLICATION CLIENT.
This allows monitoring tools to not require a SUPER privilege any more,
so is safer in overloaded situations, as well as being more secure, as
lighter privileges can be given to users of such tools or scripts.
UNHANDLED, CONFUSING ERROR
The main confusion with the error message is that "it
implies that your data dictionary may now be out of
sync". This patch will remove the unwanted and the
misleading error message by not doing an unnecessary
operation in the error handling code.

PROBLEM:
--------
When binary log statements are replayed on the slave, BEGIN is represented
in com_counters but COMMIT is not. Similarly in 'ROW' based replication
'INSERT','UPDATE',and 'DELETE' com_counters are not getting incremented
when the binary log statements are replayed at slave.
ANALYSIS:
---------
In 'ROW' based replication for COMMIT,INSERT,UPDATE and DELETE operations
following special events are invoked.
Xid_log_event,Write_rows_log_event,Update_rows_log_event,Update_rows_log_event.
The above mentioned events doesn't go through the parser where the
'COM_COUNTERS' are incremented.
FIX:
-----
Increment statements are added at appropriate events.
Respective functions are listed below.
'Xid_log_event::do_apply_event'
'Write_rows_log_event::do_before_row_operations'
'Update_rows_log_event::do_before_row_operations'
'Delete_rows_log_event::do_before_row_operations'

Added code to increment counts for 'COM_INSERT','COM_UPDATE',
'COM_DELETE' and 'COM_COMMIT'during ROW based replicaiton
Problem - this failure occured in the test added for the fix of the
bug-13333431. The basic problem of the failure was the
value of the report_port which persisted even after the end
of the test (ie. rpl_end.inc). So this causes the assertion
in the test to fail if it is executed again.
Fix - restarted the server with the default value being passed to the
report_port after testing the two expected case so that in the
next run of the test we will not encounter the previous value of
report_port.

Merge + fixed bug that __NR_clock_gettime didn't work in 5.5
Description: When the table has more than one unique or primary key,
INSERT... ON DUP KEY UPDATE statement is sensitive to the order in which
the storage engines checks the keys. Depending on this order, the storage
engine may determine different rows to mysql, and hence mysql can update
different rows on master and slave.
Solution: We mark INSERT...ON DUP KEY UPDATE on a table with more than on unique
key as unsafe therefore the event will be logged in row format if it is available
(ROW/MIXED). If only STATEMENT format is available, a warning will be thrown.

Make the slave options --replicate-* dynamic variables so that these
options can be changed dynamically while the server is running,
which enables users to modify replication filtering rules without
having to stop and restart the server.
This is accomplished by just requiring that the slave threads are
stopped when these options are set dynamically. Since filtering
rules are only used by the SQL slave thread, setting them while the
thread is not running avoids the need for locking.
