As the result of DOUBLE claculations can be bigger
than DBL_MAX constant we use in code, we shouldn't use this constatn
as a biggest possible value.
Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
that any rtree_area_increase result will be less so we return valid
key. Though in rtree_area_increase function we calculate the area
of the rectangle, so the result can be 'inf' if the rectangle is
huge enough, which is bigger than DBL_MAX.

Code of the rtree_pick_key modified so we always return a valid key.

end-of-line check missed in Gis_read_stream::get_next_word,
what can lead to crashes (expecially with NULL strings).

End-of-line check added

in get_index_for_order(), don't walk over the end of the index key parts
when matching index description and needed ordering.

'mysqld_wait_started' don't return prematurely because of an old
pidfile

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).

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()

  Backport of correction for Mac OS X build problem, global variable not
  initiated is "common" and can't be used in shared libraries, unless
  special flags are used (bug#26218)

This fixes bug#16635:
   Error messages wrong: absolute path names, "%s" format code

This bug manifested itself for join queries with GROUP BY and HAVING clauses
whose SELECT lists contained DISTINCT. It occurred when the optimizer could
deduce that the result set would have not more than one row.
The bug could lead to wrong result sets for queries of this type because
HAVING conditions were erroneously ignored in some cases in the function
remove_duplicates.   

unpack_fields() didn't expect NULL_LENGHT in the field's descriptions.
In this case we get NULL in the resulting string so cannot use
strdup_root to make a copy of it.
strdup_root changed with strmake_root as it's NULL-safe

gettimeofday() can fail and presumably, so can time().
Keep an eye on it.

Since we have no data on this at all so far, we just
retry on failure (and log the event), assuming that
this is just an intermittant failure. This might of
course hang the threat until we succeed. Once we know
more about these failures, an appropriate more clever
scheme may be picked (only try so many times per thread,
etc., if that fails, return last "good" time() we got or
some such).  Using sql_print_information() to log as this
probably only occurs in high load scenarios where the debug-
trace likely is disabled (or might interfere with testing
the effect).  No test-case as this is a non-deterministic
issue.
