replication
              
MySQL server uses wrong lock type (always TL_READ instead of
TL_READ_NO_INSERT when appropriate) for tables used in
subqueries of UPDATE statement. This leads in some cases to
a broken replication as statements are written in the wrong
order to the binlog.

sql/sql_yacc.yy:
  * Set lock_option to either TL_READ_NO_INSERT or
    TL_READ for any sub-SELECT following UPDATE.
  * Changed line adjusted for parser identation
    rules; code begins at column 13.

can be interpreted as a shell metacharacter in some circumstances.
For example, it is interpreted as a command separator when invoking
a debugger.

mysql-test/lib/mtr_cases.pm:
  Use ':' as the separator on non-Windows platforms.
mysql-test/mysql-test-run.pl:
  Remove unnecessary use of the separator.

The problem was that appending values to the end of an existing
ENUM or SET column was being treated as table data modification,
preventing a immediately (fast) table alteration that occurs when
only table metadata is being modified.

The cause was twofold: adding a enumeration or set members to the 
end of the list of valid member values was not being considered
a "compatible" table alteration, and for SET columns, the check
was being done upon the max display length and not the underlying
(pack) length of the field.

The solution is to augment the function that checks wether two ENUM
or SET fields are compatible -- by comparing the pack lengths and
performing a limited comparison of the member values.

sql/field.cc:
  Check whether two fields can be considered 'equal' for table
  alteration purposes. Fields are equal if they retain the same
  pack length and if new members are added to the end of the list.
sql/field.h:
  Add comment and remove method.

The bug is not related to MERGE table or TRIGGER. More correct description
would be 'assertion on multi-table UPDATE + NATURAL JOIN + MERGEABLE VIEW'.
On PREPARE stage(see test case) we call mark_common_columns() func which
creates ON condition for NATURAL JOIN and sets appropriate
table read_set bitmaps for fields which are used in ON condition.
On EXECUTE stage mark_common_columns() is not called, we set
necessary read_set bitmaps in setup_conds(). But 'B.f1' field
is already processed and related item alredy fixed before
setup_conds() as updated field and setup_conds can not set
read_set bitmap because of that.
The fix is to set read_set bitmap for appropriate table field even
if Item_direct_view_ref item which represents a refernce to this field
is fixed.

Bug#46958: Assertion in Diagnostics_area::set_ok_status, 
trigger, merge table
            
The problem with break statements is that they have very
local effects. Hence a break statement within the inner loop
of a nested-loops join caused execution to proceed to the
next table even though a serious error occurred. The problem
was fixed by breaking out the inner loop into its own
method. The change empowers all errors to terminate the
execution.
            
The errors that will now halt multi-DELETE execution
altogether are 
  - triggers returning errors
  - handler errors
  - server being killed

  Bug#46958: Test result.

All statements executed by mysql_upgrade are binlogged and then are replicated to slave.
This will result in some errors. The report of this bug has demonstrated some examples.

Master and slave should be upgraded separately. All statements executed by
mysql_upgrade will not be binlogged. 
--write-binlog and --skip-write-binlog options are added into mysql_upgrade. 
These options control whether sql statements are binlogged or not. 

      
In RBR, 'DROP TEMPORARY TABLE IF EXISTS...' statement is binlogged when the table
does not exist.
      
In fact, 'DROP TEMPORARY TABLE ...' statement should never be binlogged in RBR
no matter if the table exists or not. 
This patch addresses this by checking whether we are dropping a
temporary table or not, when building the custom drop statement.

HA_ERR_WRONG_INDEX
      
In RBR, disabling keys on slave table will break replication when
updating or deleting a record. When the slave thread tries to
find the row, by searching in the storage engine, it checks
whether the table has a key or not. If it has one, then the slave
thread uses it to search the record.
      
Nonetheless, the slave only checks whether the key exists or not,
it does not verify if it is active. Should the key be
disabled (eg, DBA has issued an ALTER TABLE ... DISABLE KEYS)
then it will result in error: HA_ERR_WRONG_INDEX.
      
This patch addresses this issue by making the slave thread also
check whether the key is active or not before actually using it.

The failure is not reproduced on 5.1, so enable the 'rpl_cross_version' test.

mysql-test/suite/rpl/t/disabled.def:
  Got rid of the line for enabling 'rpl_cross_version' test.

Network error happened here, but it can be caused by CR_CONNECTION_ERROR, 
CR_CONN_HOST_ERROR, CR_SERVER_GONE_ERROR, CR_SERVER_LOST, ER_CON_COUNT_ERROR, 
and ER_SERVER_SHUTDOWN. We just check CR_SERVER_LOST here, so the test fails.

To fix the problem, check all errors that can be cause by the master shutdown.

mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test:
  Added a 'if' sentence to check all errors that can be cause by the master shutdown.
mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result:

Invalid (old?) table or database name in logs

Problem was still not completely fixed, due to
qouting.

This is the server side only fix (in explain_filename),
the change from filename_to_tablename to use explain_filename
in the InnoDB code must be done before the bug is
fixed.

when compiled with Sun Studio compiler).

The thing is that Sun Studio compiler calls destructor of stack
objects when pthread_exit() is called. That triggered an assertion
in DBUG_ENTER()/DBUG_RETURN() validation logic (if DBUG_ENTER() is
used in the beginning of function, all returns should be replaced
by DBUG_RETURN/DBUG_VOID_RETURN macros).

A fix is to explicitly use DBUG_LEAVE macro.

                               value from the index (PRIMARY)


With the fix for BUG#46760, we correctly flag the presence of row_type 
only when it's actually changed and enables the FAST ALTER TABLE which was
disabled with the BUG#39200.

So the changes made by BUG#46760 makes MySQL data dictionaries to be out of 
sync but they are handled already by InnoDB with this BUG#44030.

The test was originally written to handle this but we requested Innodb to
update the test as the data dictionaries were in sync after the fix for 
BUG#39200.

Adjusting the innodb-autoinc testcase as mentioned in the comments.

mysql-test/lib/mtr_cases.pm:
  Re-enable the innodb-autoinc test case for plugin as we have a common
  result file.

  Adjust the innodb-autoinc testcase as the patch for BUG#46760 enables the 
  FAST ALTER TABLE and makes the data dictonaries go out of sync. This is 
  expected in the testcase.
mysql-test/t/innodb-autoinc.test:
