ucs2 doesn't provide required by fulltext ctype array. Crash
happens because fulltext attempts to use unitialized ctype
array.

Fixed by converting ucs2 fields to compatible utf8 analogue.

  available. Currently used by fulltext search to find compatible

myisam_sort_buffer_size.

An incorrect length of the sort buffer was used when calculating the
maximum number of keys. When myisam_sort_buffer_size is small enough,
this could result in the number of keys < number of
BUFFPEK structures which in turn led to use of uninitialized BUFFPEKs.

Fixed by correcting the buffer length calculation.


myisam/sort.c:
  Use a correct buffer length when calculating the maximum number of keys.
  Assert that for each BUFFPEK structure there is at least one
  corresponding key. Otherwise we would fail earlier and not reach
  merge_buffers().

DELETE query against memory table with btree index may remove
not all matching rows. This happens only when DELETE uses
index read method to find matching rows. E.g. for queries
like DELETE FROM t1 WHERE a=1.

Fixed by reverting fix for BUG9719 and applying proper solution.


heap/hp_delete.c:
  Reverted fix for BUG9719 as it makes queries like
  DELETE FROM t1 WHERE a=1 to remove not all matching
  rows (assuming this is memory table and there is btree
  key over `a`).
  
  This happens because we calculate info->lastkey_len in
  heap_rkey(). When we enter heap_rnext(), info->lastkey_len
  is 0 (set by hp_rb_delete_key()). We need to preserve
  info->lastkey_len in this situation, otherwise
  tree_search_key() will always return smallest value in
  a tree.
heap/hp_rfirst.c:
  If we're performing index_first on a table that was taken from
  table cache, info->lastkey_len is initialized to previous query.
  Thus we set info->lastkey_len to proper value for subsequent
  heap_rnext() calls.
  This is needed for DELETE queries only, otherwise this variable is
  not used.
  Note that the same workaround may be needed for heap_rlast(), but
  for now heap_rlast() is never used for DELETE queries.
heap/hp_rnext.c:
  An optimization for DELETE queries that use index_first()/index_next().
  Use faster tree_search_edge() instead of tree_search_key().

which does not work.  Removing these attempted privileges makes
this identical to option 5 so remove it completely.  The spirit
of the program appears to be aimed at database privileges, so do
not add another option for granting global privileges as it may
be unexpected.  Fixes bug#14618 (same as previous patch, this
time applied to -maint tree).


scripts/mysql_setpermission.sh:
  Option 6 tries to apply global privileges at the database
  level which does not work - remove it.

When using concurrent insert with parallel index reads, it could
happen that reading sessions found keys that pointed to records
yet to be written to the data file. The result was a report of
a corrupted table. But it was false alert.

When inserting a record in a table with indexes, the keys are
inserted into the indexes before the record is written to the data
file. When the insert happens concurrently to selects, an
index read can find a key that references the record that is not
yet written to the data file. To avoid any access to such record,
the select saves the current end of file position when it starts.
Since concurrent inserts are always appended at end of the data
file, the select can easily ignore any concurrently inserted record.

The problem was that the ignore was only done for non-exact key
searches (partial key or using >, >=, < or <=).

The fix is to ignore concurrently inserted records also for
exact key searches.

No test case. Concurrent inserts cannot be tested with the test
suite. Test cases are attached to the bug report.

 SELECT statement itself returns empty.

As a result of this bug 'SELECT AGGREGATE_FUNCTION(fld) ... GROUP BY'
can return one row instead of an empty result set.

When GROUP BY only has fields of constant tables
(with a single row), the optimizer deletes the group_list.
After that we lose the information about whether we had an
GROUP BY statement. Though it's important
as SELECT min(x) from empty_table; and
   SELECT min(x) from empty_table GROUP BY y; have to return
different results - the first query should return one row,
second - an empty result set.
So here we add the 'group_optimized_away' flag to remember this case
when GROUP BY exists in the query and is removed
by the optimizer, and check this flag in end_send_group()
