listpack over 8192 cause 'error: cursor out of range' panic error

[freekatz]

Thanks for your awesome work! I found a bug when I test the rdb tool on my Mac about Redis7.2.

• redis

redis-server -v                                          
Redis server v=7.2.1 sha=00000000:0 malloc=libc bits=64 build=7b8617dd94058f85

• test data

redis-benchmark -c 1  --dbnum 0 -d 10000 -r 2000 -t rpush

• code should be

         //  https://github.com/HDT3213/rdb/blob/887c2ca2556ffff3be967e74147ec5fe428af8b1/core/listpack.go#L105
	case 0: // 1111 0000 -> str, 4 bytes len
		var lenBytes []byte
		lenBytes, err = readBytes(buf, cursor, 4)
		if err != nil {
			return nil, 0, err
		}
		//strLen := int(binary.BigEndian.Uint32(lenBytes))
		strLen := int(binary.LittleEndian.Uint32(lenBytes))
		result, err := readBytes(buf, cursor, strLen)
		if err != nil {
			return nil, 0, err
		}
		//length = readVarInt(buf, cursor) // read element length
		length = uint32(len(result)) // read element length
		return result, length, nil
