Marko Mäkelä 9fac857f26 MDEV-34283 A misplaced btr_cur_need_opposite_intention() check may fail to prevent hangs ... btr_cur_t::search_leaf(): Invoke btr_cur_need_opposite_intention() after positioning page_cur.rec so that the record will be in the intended page. This is something that was broken in commit f2096478d5 or commit de4030e4d4 or related changes. btr_cur_need_opposite_intention(): Add a debug assertion that would catch the misuse. The "next line of defence" that should have caught this bug in debug builds are assertions that mtr_t::m_memo contains MTR_MEMO_X_LOCK for the dict_index_t::lock. When btr_cur_need_opposite_intention() holds, we should escalate to acquiring an exclusive index->lock in btr_cur_t::pessimistic_search_leaf().
