A prepared backup from Mariabackup does not really need to contain any redo log file, because all log will have been applied to the data files. When the user copies a prepared backup to a data directory (overwriting existing files), it could happen that the data directory already contained redo log files from the past. mariabackup --copy-back) would delete the old redo log files, but a user’s own copying script might not do that. To prevent corruption caused by mixing an old redo log file with data files from a backup, starting with MDEV-13311, Mariabackup would create a zero-length ib_logfile0 that would prevent startup. Actually, there is no need to prevent InnoDB from starting up when a single zero-length file ib_logfile0 is present. Only if there exist multiple data files of different lengths, then we should refuse to start up due to inconsistency. A single zero-length ib_logfile0 should be treated as if the log files were missing: create new log files according to the configuration. open_log_file(): Remove. There is no need to open the log files at this point, because os_file_get_status() already determined the size of the file. innobase_start_or_create_for_mysql(): Move the creation of new log files a little later, not when finding out that the first log file does not exist, but after finding out that it does not exist or it exists as a zero-length file.
