a too large value": the bug was that if MySQL generated a value for an auto_increment column, based on auto_increment_* variables, and this value was bigger than the column's max possible value, then that max possible value was inserted (after issuing a warning). But this didn't honour auto_increment_* variables (and so could cause conflicts in a master-master replication where one master is supposed to generated only even numbers, and the other only odd numbers), so now we "round down" this max possible value to honour auto_increment_* variables, before inserting it. mysql-test/r/rpl_auto_increment.result: result update. Before the fix, the result was that master inserted 127 in t1 (which didn't honour auto_increment_* variables!), instead of failing with "duplicate key 125" like now. mysql-test/t/rpl_auto_increment.test: Test for BUG#20524 "auto_increment_* not observed when inserting a too large value". We also check the pathological case (table t2) where it's impossible to "round down". The fixer of BUG#20573 will be able to use table t2 for testing his fix. sql/handler.cc: If handler::update_auto_increment() generates a value larger than the field's max possible value, we used to simply insert this max possible value (after pushing a warning). Now we "round down" this max possible value to honour auto_increment_* variables (if at all possible), before trying the insertion.
