InnoDB startup was discovering undo tablespaces in a dirty way. It was reading a possibly stale copy of the TRX_SYS page before processing any redo log records. srv_start(): Do not call buf_pool_invalidate(). Invoke trx_rseg_get_n_undo_tablespaces() after the recovery has been initiated. recv_recovery_from_checkpoint_start(): Assert that the buffer pool is empty. This used to be guaranteed by the buf_pool_invalidate() call. trx_rseg_get_n_undo_tablespaces(): Move to the calling compilation unit, and reimplement in a simpler way. srv_undo_tablespace_create(): Remove the constant parameter size=SRV_UNDO_TABLESPACE_SIZE_IN_PAGES. srv_undo_tablespace_open(): Reimplement in a cleaner way, with more robust error handling. srv_all_undo_tablespaces_open(): Split from srv_undo_tablespaces_init(). srv_undo_tablespaces_init(): Read all "undo001","undo002" tablespace files directly, without consulting the TRX_SYS page via calling trx_rseg_get_n_undo_tablespaces(). This is joint work with Thirunarayanan Balathandayuthapani.
