recovery, tolerate clustered index records whose externally stored columns have not been written. This should remove the assertion failures that were reported as Mantis issue#58, issue#62, issue#64. trx_is_recv(): New function: TRUE if this transaction is rolling back an incomplete transaction in crash recovery. enum trx_rbmode: Rollback modes: no rollback, normal rollback, crash recovery. btr_cur_pessimistic_delete(), btr_free_externally_stored_field(), btr_rec_free_externally_stored_fields(): Replace the ibool parameter with enum trx_rbmode. btr_free_externally_stored_field(): If field_ref is zero, return but assert ut_a(rbmode == RB_RECOVERY). Unless InnoDB has crashed while inserting a clustered index record, field_ref should not be zero. btr_rec_free_updated_extern_fields(): Add the parameter enum trx_rbmode. btr_cur_pessimistic_update(): Pass the rbmode parameter to btr_rec_free_updated_extern_fields(). row_undo_ins(), row_undo_mod_upd_del_sec(): If row_build_index_entry() fails, assert trx_is_recv() and skip this secondary index. row_undo_mod_upd_del_sec(): Empty the heap at the end of each loop iteration in order to conserve memory and to reduce the number of low-level memory allocations. |
