use partial primary key if another index can prevent filesort The fix for bug #28404 causes the covering ordering indexes to be preferred unconditionally over non-covering and ref indexes. Fixed by comparing the cost of using a covering index to the cost of using a ref index even for covering ordering indexes. Added an assertion to clarify the condition the local variables should be in. mysql-test/include/mix1.inc: Bug #36259: fixed a non-stable test case mysql-test/r/innodb_mysql.result: Bug #36259 and #45828 : test case mysql-test/t/innodb_mysql.test: Bug #36259 and #45828 : test case sql/sql_select.cc: Bug #36259 and #45828 : don't consider covering indexes supperior to ref keys.
