Objects of the class Item_equal contain an auxiliary member
eval_item of the type cmp_item that is used only for direct
evaluation of multiple equalities. Currently a multiple equality
is evaluated directly only in the cases when the equality holds
at most for one row in the result set.
The compare collation of eval_item was determined incorectly.
It could lead to returning incorrect results for some queries.

Though we would find the reference to a field, that doesn't mean we can then use
it to set some values. It could be a reference to another field. If it is NULL,
don't try to use it to set values in the Item_field and instead return an error.
Over the previous patch, this signals an error at the location of the error, rather
than letting the subsequent deref signal it.

"INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values".
When in an INSERT ON DUPLICATE KEY UPDATE, using
an autoincrement column, we inserted some autogenerated values and
also updated some rows, some autogenerated values were not used
(for example, even if 10 was the largest autoinc value in the table
at the start of the statement, 12 could be the first autogenerated
value inserted by the statement, instead of 11). One autogenerated
value was lost per updated row. Led to exhausting the range of the
autoincrement column faster.
Bug introduced by fix of BUG#20188; present since 5.0.24 and 5.1.12.
This bug breaks replication from a pre-5.0.24 master.
But the present bugfix, as it makes INSERT ON DUP KEY UPDATE
behave like pre-5.0.24, breaks replication from a [5.0.24,5.0.34]
master to a fixed (5.0.36) slave! To warn users against this when
they upgrade their slave, as agreed with the support team, we add
code for a fixed slave to detect that it is connected to a buggy
master in a situation (INSERT ON DUP KEY UPDATE into autoinc column)
likely to break replication, in which case it cannot replicate so
stops and prints a message to the slave's error log and to SHOW SLAVE
STATUS.
For 5.0.36->[5.0.24,5.0.34] replication we cannot warn as master
does not know the slave's version (but we always recommended to users
to have slave at least as new as master).
As agreed with support, I'll also ask for an alert to be put into
the MySQL Network Monitoring and Advisory Service.
mysql-test/r/rpl_insert_id.result:
results to check the bugfix; without the bugfix, you would see, in
master and slave:
"3,2" instead of "2,2" for the INSERT VALUES testcase,
"11,6,..." instead of "6,6,..." for the INSERT SELECT testcase.
mysql-test/t/rpl_insert_id.test:
testing that BUG#24432 is fixed
sql/log_event.cc:
A trick to force the master to pretend it is old and features BUG#24432.
To do fast lookups in the list of known bugs by version, we compute
the 3 X.Y.Z numbers from the master's version string and cache that
into a new member Format_description_log_event::server_version_split.
We do this computation in the event's two constructors.
A simple prevention against buffer overrun when reading the master's
version from a binlog event (assume the event is corrupted on disk,
and so the version string on disk is longer than ST_SERVER_VER_LEN
(50), then we would not get a closing 0 at the end of the class member.
sql/log_event.h:
new member to hold the "split server version" (3 numbers X.Y.Z),
and a method to compute this from the version string.
sql/slave.cc:
a function which tells, based on master's version (as found
in the Format_description event in the relay log being executed),
if master can have a certain bug. This function uses a list of
bug_id / first_version_with_bug / first_version_with_fix.
If the test is positive, a short error message is put into SHOW SLAVE
STATUS, and a verbose message is put into the slave's error log.
The caller is expected to stop the slave in this case.
sql/slave.h:
new function to test if the replication master has a bug
sql/sql_insert.cc:
Fix for BUG#24432:t he reason was a misplaced restore_auto_increment()
(misplaced when fixing BUG#20188). Indeed, when updating the row,
it is clear that the autogenerated auto_increment value will not be
used for this row (and if by "chance" the autoinc value present
in the updated row is >= to the not used autogenerated value,
adjust_next_insert_id_after_explicit_value() will fix next_insert_id).
We also add code for a fixed slave to detect that it is connected to
a buggy master (in which case it cannot replicate so stops).
mysql-test/r/rpl_known_bugs_detection.result:
see that SHOW SLAVE STATUS prints information that slave found a bug
in master, and does not execute the dangerous event (table stays
empty).

DATETIME type.
mysql-test/r/view.result:

mysql-test/t/view.test:
Added a test case for bug #26124.
Before this change, a local variables in stored procedures / stored functions
or triggers, when declared with a type of bit(N), would not evaluate their
value properly.
The problem was that the data was incorrectly typed as a string,
causing for example bit b'1', implemented as a byte 0x01, to be interpreted
as a string starting with the character 0x01. This later would cause
implicit conversions to integers or booleans to fail.
The root cause of this problem was an incorrect translation between field
types, like bit(N), and internal types used when representing values in Item
objects.
Also, before this change, the function HEX() would sometime print extra "0"
characters when invoked with bit(N) values.
With this fix, the type translation (sp_map_result_type, sp_map_item_type)
has been changed so that bit(N) fields are represented with integer values.
A consequence is that, for the function HEX(), when called with a stored
procedure local variable of type bit(N) as argument, HEX() is provided with an
integer instead of a string, and therefore does not print "0" padding.
A test case for Bug 12976 was present in the test suite, and has been updated.

The bug could cause choosing a sub-optimal execution plan for
a single-table query if a unique index with many null keys were
defined for the table.
It happened because the code of the check_quick_keys function
made an assumption that any key may occur in an unique index
only once. Yet this is not true for keys with nulls that may
have multiple occurrences in the index.

Two problems here:
Problem 1:
While constructing the join columns list the optimizer does as follows:
1. Sets the join_using_fields/natural_join members of the right JOIN
operand.
2. Makes a "table reference" (TABLE_LIST) to parent the two tables.
3. Assigns the join_using_fields/is_natural_join of the wrapper table
using join_using_fields/natural_join of the rightmost table
4. Sets join_using_fields to NULL for the right JOIN operand.
5. Passes the parent table up to the same procedure on the upper
level.
Step 1 overrides the the join_using_fields that are set for a nested
join wrapping table in step 4.
Fixed by making a designated variable SELECT_LEX::prev_join_using to
pass the data from step 1 to step 4 without destroying the wrapping
table data.
Problem 2:
The optimizer checks for ambiguous columns while transforming
NATURAL JOIN/JOIN USING to JOIN ON. While doing that there was no
distinction between columns that are used in the generated join
condition (where ambiguity can be checked) and the other columns
(where ambiguity can be checked only when resolving references
coming from outside the JOIN construct itself).
Fixed by allowing the non-USING columns to be present in multiple
copies in both sides of the join and moving the ambiguity check
to the place where unqualified references to the join columns are
resolved (find_field_in_natural_join()).
