The optimization that uses a unique index to remove GROUP BY did not 
ensure that the index was actually used, thus violating the ORDER BY
that is implied by GROUP BY.
Fixed by replacing GROUP BY with ORDER BY if the GROUP BY clause contains
a unique index over non-nullable field(s). In case GROUP BY ... ORDER BY 
null is used, GROUP BY is simply removed.


mysql-test/include/mix1.inc:
  Bug#30596: Test case for InnoDB
  Here, as opposed to for MyISAM, row lookup is done using index 
  whenever the index covers the group list.
mysql-test/r/distinct.result:
  Bug#30596: Changed test case. 
  Prior to Bug#16458, These queries use temp table and filesort. The
  bug was that they used a temp table. However, that patch removed
  filesort also, in which case we can no longer gurantee correct ordering.
mysql-test/r/group_by.result:
  Bug#30596: Correct result
  The test case for IGNORE INDEX FOR GROUP BY gets degraded performance 
  (unneccesary filesort). This is due to Bug#30665, which will be fixed separately.

sql/sql_cache.cc:
  SCCS merged

Killing a SELECT query with KILL QUERY or KILL CONNECTION
causes a server crash if the query cache is enabled.

Normal evaluation of a query may be interrupted by the
KILL QUERY/CONNECTION statement, in this case the mysql_execute_command
function returns TRUE, and the thd->killed flag has true value.
In this case the result of the query may
be cached incompletely (omitting call to query_cache_insert inside
the net_real_write function), and next call to query_cache_end_of_result
may lead to server crash.
Thus, the query_cache_end_of_result function has been modified to abort
query cache in the case of killed thread.



sql/sql_cache.cc:
  Fixed bug #30201.
  The  query_cache_end_of_result function has been modified to abort query
  cache in the case of query execution failure. Also this function has been
  modified to remove incomplete query block.

When using --log --log-output=table, we increment Table_locks_immediate
with every query.  The wait_condition.inc runs a query a variable number
of times, depending on server load, etc.  This is a problem, when the
test is checking the Table_locks_immediate value.

Fix is to adjust the Table_locks_immediate value based on how many times
the wait_condition query was executed.


mysql-test/include/wait_condition.inc:
  Add a $wait_condition_reps variable, which lets the caller check how
  many times the wait_condition query was executed.
  
  This is used in the main.status test to adjust the value of
  Table_locks_immediate (it gets incremented with each query
  when --log --log-output=table).
mysql-test/t/status.test:
  Adjust Table_locks_immediate value based on how many times the
  wait_condition query had to run.
