Mariabackup 10.2.7 would delete the redo log files after a successful --prepare operation. If the user is manually copying the prepared files instead of using the --copy-back option, it could happen that some old redo log file would be preserved in the restored location. These old redo log files could cause corruption of the restored data files when the server is started up. We prevent this scenario by creating a "poisoned" redo log file ib_logfile0 at the end of the --prepare step. The poisoning consists of simply truncating the file to an empty file. InnoDB will refuse to start up on an empty redo log file. copy_back(): Delete all redo log files in the target if the source file ib_logfile0 is empty. (Previously we did this if the source file is missing.) SRV_OPERATION_RESTORE_EXPORT: A new variant of SRV_OPERATION_RESTORE when the --export option is specified. In this mode, we will keep deleting all redo log files, instead of truncating the first one. delete_log_files(): Add a parameter for the first file to delete, to be passed as 0 or 1. innobase_start_or_create_for_mysql(): In mariabackup --prepare, tolerate an empty ib_logfile0 file. Otherwise, require the first redo log file to be longer than 4 blocks (2048 bytes). Unless --export was specified, truncate the first log file at the end of --prepare.
