Hello,
I have done a J2ME implementation of the RELOAD message system and I would
like to ask about some parts that I might have misinterpreted.
1. RELOAD specifies a length value as the length of the destination_data
field. I think this might be redundant since in each of the cases (node,
resource or compressed) there is already a length field before the data.
Same thing happens in the Config_Update (page 70), config_data and kinds, do
also have a length.
2. In several parts of the code there are certain list fields, for instance
the destination_list, this field comes with a destination_list_length that
is used when parsing a destination_list.
The problem is that in many parts of the code, this kind of lists do not
have a length defined.
A solution would be to specify in Section 5.3.1.1. "Common Definitions",
that all lists should include a uint 16 length before the list.
Some of this cases are:
MessageContents
struct {
uint16 message_code;
opaque message_body<0..2^32-1>;
* **uint16 extensions_length;***
MessageExtensions extensions<0..2^32-1>;
} MessageContents;
SecurityBlock
struct {
* **uint16 certificates_length;***
GenericCertificate certificates<0..2^16-1>;
Signature signature;
} SecurityBlock;
3. There is no "model" specified in the diagram in page 92. The case
structure depends on a model field that is not there, it might be a typo.
***enum {single_value (1), array (2), dictionary (3), (255)} ModelType;***
struct {
KindId kind;
uint64 generation;
uint16 length;
* **ModelType model;***
select (model) {
case single_value: ; /* Empty */
case array:
ArrayRange indices<0..2^16-1>;
case dictionary:
DictionaryKey keys<0..2^16-1>;
/* This structure may be extended */
} model_specifier;
} StoredDataSpecifier;
4. In page 139 there is a leave_ans (code value 18) specified. Although it
probably is a simple ACK, may be it should be specified in RELOAD too?
Thanks for the time,
Jaime J.
