Marko Mäkelä added a comment - 2019-10-11 11:15 In the error log, I noticed that the preceding test main.drop_bad_db_type had inadvertently enabled all DBUG tracing by executing SET debug_dbug= '-d,…' ; instead of following the preferred pattern of SET @save_dbug=@@debug_dbug; SET debug_dbug= '+d,…' ; … SET debug_dbug=@save_dbug; The test was introduced years ago. I searched MariaDB 5.5 for similar tests, and adjusted the main ones (notably, not --suite=rpl , because I believe that alice has been requested to do that).
