51a9116638 BUG#37145 Killing a statement doing DDL may log binlog event with error code 1053
When the thread executing a DDL was killed after finished its
execution but before writing the binlog event, the error code in
the binlog event could be set wrongly to ER_SERVER_SHUTDOWN or
ER_QUERY_INTERRUPTED.

This patch fixed the problem by ignoring the kill status when
constructing the event for DDL statements.

This patch also included the following changes in order to
provide the test case.

 1) modified mysqltest to support variable for connection command

 2) modified mysql-test-run.pl, add new variable MYSQL_SLAVE to
    run mysql client against the slave mysqld.

5803e10628 BUG#36737 - having + full text operator crashes mysql
MATCH() function accepts column list as an argument. It was possible to override
this requirement with aliased non-column select expression. Which results in
server crash.

With this fix aliased non-column select expressions are not accepted by MATCH()
function, returning an error.

d096079d33 Bug#37553: MySql Error Compare TimeDiff & Time
We pretended that TIMEDIFF() would always return positive results;
this gave strange results in comparisons of the TIMEDIFF(low,hi)<TIME(0)
type that rendered a negative result, but still gave false in comparison.
We also inadvertantly dropped the sign when converting times to
decimal.

CAST(time AS DECIMAL) handles signs of the times correctly.
TIMEDIFF() marked up as signed. Time/date comparison code switched to
signed for clarity.

  time values now.

ab9ecae47b BUG#38842 - Fix for 25951 seems incorrect
With fix for bug 25951 index hints are ignored for fulltext
searches, as handling of fulltext indexes is different from
handling regular indexes. Meaning it is not possible to
implement true index hints support for fulltext indexes within
the scope of current fulltext architecture.

The problem is that prior to fix for bug 25951, some useful
index hints still could be given for boolean mode searches.

This patch implements special index hints support for fulltext
indexes with the following characteristics:
- all index hints are still ignored for NLQ mode searches -
  it cannot work without an index;
- for 5.1 and up index hints FOR ORDER BY and FOR GROUP BY are
  still ignored for fulltext indexes;
- boolean mode searches honor USE/FORCE/IGNORE INDEX hints;
- as opposed to index hints for regular indexes, index hints
  for fulltext BOOLEAN mode searches affect the usage of the
  index for the whole query.

  A test case for BUG#38842.
mysql-test/t/fulltext.test:
  A test case for BUG#38842.
sql/item_func.cc:
  For boolean mode searches, which can work without fulltext
  index, use keys_in_use_for_query bitmap instead of keys_in_use.
  
  The effect is that boolean mode searches now honor index hints.

e7a6e86f78 Bug #38637: COUNT DISTINCT prevents NULL testing in HAVING clause
IS NULL was not checking the correct row in a HAVING context.
At the first row of a new group (where the HAVING clause is evaluated)
the column and SELECT list references in the HAVING clause should 
refer to the last row of the previous group and not to the current one. 
This was not done for IS NULL, because it was using Item::is_null() doesn't
have a  Item_is_null_result() counterpart to access the data from the 
last row of the previous group. Note that all the Item::val_xxx() functions 
(e.g. Item::val_int()) have their _result counterparts (e.g. Item::val_int_result()).

Fixed by implementing a is_null_result() (similarly to int_result()) and
calling this instead of is_null() column and SELECT list references inside
the HAVING clause.

ae4a35fd5c Bug#37662 nested if() inside sum() is parsed in exponential time
min() and max() functions are implemented in MySQL as macros.
This means that max(a,b) is expanded to: ((a) > (b) ? (a) : (b))
Note how 'a' is quoted two times.
Now imagine 'a' is a recursive function call that's several 10s of levels deep.
And the recursive function does max() with a function arg as well to dive into
recursion.
This means that simple function call can take most of the clock time.
Identified and fixed several such calls to max()/min() : including the IF() 
sql function implementation.

1164e2bc7a Bug#33851 Passing UNSIGNED param to EXECUTE returns ERROR 1210
The problem is that passing anything other than a integer to a limit
clause in a prepared statement would fail. This limitation was introduced
to avoid replication problems (e.g: replicating the statement with a
string argument would cause a parse failure in the slave).

The solution is to convert arguments to the limit clause to a integer
value and use this converted value when persisting the query to the log.

754c3f51ec Bug#30787: Stored function ignores user defined alias.
Simple subselects are pulled into upper selects. This operation substitutes the
pulled subselect for the first item from the select list of the subselect.
If an alias is defined for a subselect it is inherited by the replacement item.
As this is done after fix_fields phase this alias isn't showed if the
replacement item is a stored function. This happens because the Item_func_sp::make_field
function makes send field from its result_field and ignores the defined alias.

Now when an alias is defined the Item_func_sp::make_field function sets it for
the returned field.

9e6bb07d38 Bug#30889: filesort and order by with float/numeric crashes server
There are two problems with ROUND(X, D) on an exact numeric 
(DECIMAL, NUMERIC type) field of a table:
1) The implementation of the ROUND function would change the number of decimal
places regardless of the value decided upon in fix_length_and_dec. When the
number of decimal places is not constant, this would cause an inconsistent
state where the number of digits was less than the number of decimal places,
which crashes filesort.

Fixed by not allowing the ROUND operation to add any more decimal places than
was decided in fix_length_and_dec.

2) fix_length_and_dec would allow the number of decimals to be greater than
the maximium configured value for constant values of D. This led to the same 
crash as in (1).

Fixed by not allowing the above in fix_length_and_dec.

367fc73e3c Bug #29804 UDF parameters don't contain correct string length
Previously, UDF *_init functions were passed constant strings with erroneous lengths. The length came from the containing variable's size, not the length of the value itself.
    
Now the *_init functions get the constant as a null terminated string with the correct length supplied too.

4f14c13a1c Fix for BUG#31035: select from function, group by result crasher.
This actually, fix for the patch for bug-27354. The problem with
the patch was that Item_func_sp::used_tables() was updated, but
Item_func_sp::const_item() was not. So, for Item_func_sp, we had
the following inconsistency:
  - used_tables() returned RAND_TABLE, which means that the item
    can produce "random" results;
  - but const_item() returned TRUE, which means that the item is
    a constant one.

The fix is to change Item_func_sp::const_item() behaviour: it must
return TRUE (an item is a constant one) only if a stored function
is deterministic and each of its arguments (if any) is a constant
item.


mysql-test/r/sp.result:
  Update result file.
mysql-test/t/sp.test:
  Add test cases for BUG-31035, BUG-31191, BUG-31226

bebcb22183 Bug #30587: mysql crashes when trying to group by TIME div NUMBER
When calculating the result length of an integer DIV function 
the number of decimals was used without checking the result type
first. Thus an uninitialized number of decimals was used for some 
types. This caused an excessive amount of memory to be allocated 
for the field's buffer and crashed the server.

 
Fixed by using the number of decimals only for data types that 
can have decimals and thus have valid decimals number.

ebaa05efa7 Bug#27216: functions with parameters of different date types may return wrong
type of the result.

There are several functions that accept parameters of different types.
The result field type of such functions was determined based on
the aggregated result type of its arguments. As the DATE and the DATETIME
types are represented by the STRING type, the result field type
of the affected functions was always STRING for DATE/DATETIME arguments.
The affected functions are COALESCE, IF, IFNULL, CASE, LEAST/GREATEST, CASE.

Now the affected functions aggregate the field types of their arguments rather
than their result types and return the result of aggregation as their result
field type.
The cached_field_type member variable is added to the number of classes to
hold the aggregated result field type.
The str_to_date() function's result field type now defaults to the
MYSQL_TYPE_DATETIME.
The agg_field_type() function is added. It aggregates field types with help
of the Field::field_type_merge() function.
The create_table_from_items() function now uses the 
item->tmp_table_field_from_field_type() function to get the proper field
when the item is a function with a STRING result type.
