- Let index_merge allocate table handlers on quick select's MEM_ROOT, not on statement's MEM_ROOT. This is crucial for big "range checked for each record" queries, where index_merge can be created and deleted many times during query exection. We should not make O(#rows) allocations on statement's MEM_ROOT.

Analysis: The reason for the inefficent plan was that Item_subselect::is_expensive() didn't detect the special case when a subquery was optimized, but had no join plan because it either has no table, or its tables have been optimized away, or the optimizer detected that the result set is empty. Solution: Identify the special cases above in the Item_subselect::is_expensive(), and consider such degenerate subqueries inexpensive.

This bug was introduced by the patch for WL#3220. If the memory allocated for the tree to store unique elements to be counted is not big enough to include all of them then an external file is used to store the elements. The unique elements are guaranteed not to be nulls. So, when reading them from the file we don't have to care about the null flags of the read values. However, we should remove the flag at the very beginning of the process. If we don't do it and if the last value written into the record buffer for the field whose distinct values needs to be counted happens to be null, then all values read from the file are considered to be nulls and are not counted in. The fix does not remove a possible null flag for the read values. Rather it just counts the values in the same way it was done before WL #3220.

In some cases, when using views the optimizer incorrectly determined possible join orders for queries with nested outer and inner joins. This could lead to invalid execution plans for such queries.

The reason is the limitation of ReadConsole() API, it returns error if handle to redirected input is used. The fix is to use a handle returned by CreateFile("CONIN$",...), rather than GetStdHandle(STD_HANDLE_INPUT) to get the true console handle.

The output of mysqlbinlog (with "-v --base64-output=DECODE-ROWS" flags) can not always be read or parsed correctly when string columns contain single-quotes or backslash characters. The fix for this bug is to escape single-quote and backslash characters on output, so that the result is both more readable and more easily parse-able. Note that this is just for comments, so it doesn't affect the replication. sql/log_event.cc: Escape \ and ' properly for mysqlbin user comments.

with decimals=NOT_FIXED_DEC it is possible to have 'decimals' larger than 'max_length', it's not an error for temporal functions. But when Item_func_numhybrid converts the value to DECIMAL_RESULT, it must limit 'decimals' to be a valid scale of a decimal number.
