Marko Mäkelä 1c9f64e54f MDEV-36613 Incorrect undo logging for indexes on virtual columns ... Starting with mysql/mysql-server@02f8eaa998 and commit 2e814d4702 the index ID of indexes on virtual columns was being encoded insufficiently in InnoDB undo log records. Only the least significant 32 bits were being written. This could lead to some corruption of the affected indexes on ROLLBACK, as well as to missed chances to remove some history from such indexes when purging the history of committed transactions that included DELETE or an UPDATE in the indexes. dict_hdr_create(): In debug instrumented builds, initialize the DICT_HDR_INDEX_ID close to the 32-bit barrier, instead of initializing it to DICT_HDR_FIRST_ID (10). This will allow the changed code to be exercised while running ./mtr --suite=gcol,vcol. trx_undo_log_v_idx(): Encode large index->id in a similar way as mysql/mysql-server@e00328b4d0 but using a different implementation. trx_undo_read_v_idx_low(): Decode large index->id in a similar way as mach_u64_read_much_compressed().
