the master but on the slave MySQL can decide to "downgrade" a INSERT DELAYED statement to normal insert in certain situations. One such situation is when the slave is replaying a replication feed. However INSERT DELAYED is logged even if there're no updates whereas the NORMAL INSERT is not logged in such cases. Fixed by always logging a "downgraded" INSERT DELAYED: even if there were no updates. mysql-test/r/rpl_insert_delayed.result: Bug #29571: test case mysql-test/t/rpl_insert_delayed.test: Bug #29571: test case sql/sql_insert.cc: Bug #29571: log INSERT DELAYED even if it was "downgraded" to INSERT (and there were no updates)
