[protobuf] Freeing memory for jdaf messages

[Ashwin Kini]

I have a generic query,

I'm using protobuf in C. I have 2 daemons that need to talk to each other 
over google protobuf channel.

Lets say i malloc a message on sender side, send it to protobuf functions. 
My understanding is i need to free it as i allocated it, once the call 
returns.

How about when the receiver daemon receives a callback with protobuf 
message. Who frees that message?.

I wasnt able to find any clear instructions on this.

Any help will be appreciated. Thanks in advance!

[protobuf] Tags and values

[Ashwin Kini]

Hi all,

While defining messages can the *tags *be non continous? The documentation 
never mentions the same

message abc {
optional uint32 xyz = *100*;
optional uint32 def = *200*;
optional unit32 abc = *0xDEAD01*;

}

The documentation says it needs to be unique. Agreed. Can they be non 
continous as explained in example?  . Also does it take HEX values as far 
as it falls in the range mentioned in the doc?

One more question is, can repeated fields be made required? I did a lot of 
digging, seems its not possible. Can anybody confirm? I understand required 
should be completely avoided.
