Currently execution of commit in one phase proceeds to commit by engines when binlog_commit() does not succeed. There are two issues with that: 1. absence of binlog_rollback() or lower-level `binlog_cache_data::reset()` along the following execution of the failing statement eventually will raise an assert on non-empty binlog cache, find in the MDEV description # --error assert(sql/log.cc:1712(binlog_close_connection)) # --disconnect default 2. engines, including ones that are rollback capable, commit in this particular error situation. Both effects can be observed with a new mtr test that would fail when run on a BASE of this commit. The BASE has to include MDEV-35207 et all fixes because the test is written with CREATE-TABLE-SELECTs. A new test file verifies the new behaviour to rollback including cases with a side effect of modified non-transactional engine which expose another MDEV-36027 (TODO: fix).
