Support for NULL components was incomplete for row comparison, fixed. Added support for abort_on_null at compare_row() like in 5.x sql/item_cmpfunc.h: Bug#27704: incorrect comparison of rows with NULL components Added support for abort_on_null at Item_bool_func2 like in 5.x sql/item_cmpfunc.cc: Bug#27704: incorrect comparison of rows with NULL components Support for NULL components was incomplete for row comparison, fixed. Added support for abort_on_null at compare_row() like in 5.x mysql-test/t/row.test: Test case updated for Bug#27704 (incorrect comparison of rows with NULL components) mysql-test/r/row.result: Test case updated for Bug#27704 (incorrect comparison of rows with NULL components) mysql-test/r/subselect.result: Test case updated for Bug#27704 (incorrect comparison of rows with NULL components)
