Performs basic validation for the files that have been found. Clears and builds the Log_files_dict. Determines global properties of the redo log files: format, creator, flags and uuid.
[in] | read_only | T: check file permissions only for reading, F: check for both reading and writing |
[in] | encryption_metadata | pointer to encryption metadata to be used by all redo log file IO operations except those related to the first LOG_FILE_HDR_SIZE bytes of each log file |
[out] | files | dictionary of files that have been found when FOUND_VALID_FILES is returned; otherwise stays untouched |
[out] | format | discovered format of the redo log files |
[out] | creator_name | name of creator of the files |
[out] | log_flags | discovered flags of the redo log files |
[out] | log_uuid | discovered uuid of the redo log files |
The size_capacity was computed by iterating files_list, in which we potentially could have two files with the same m_id if some bug was introduced. This should be caught easily by this check.
