That leads to inconsistencies. When a test sets SESSION 'dbug' variable like SET SESSION debug_dbug="+d,warn_during_ha_commit_trans"; it is run as a plain query in that separate thread, so the main thread remains unaffected. After that the statement run in the main thread doesn't produce expected 'dbug' errors, so the test fail. To fix that I made statement to be run in that special thread along with the plain queries. That makes the environment consistent.

Ok to push. But sayng "statements" in the comment is a big misleading, it'd be cleared if you'd say "prepared statements". Regards, Sergei
