[protobuf] Best way to share protocol buffer objects in c++
Hi, I followed the steps in the tutorial and tailor it for my needs. In my case, I have two c++ applications; one for sending messages and other for receiving. I created a proto file to define my object to be exchanged between these two distinct applications. Then, I created my object with protoc tool provided. What I want is to put this generated object class in a separate DLL or lib for enabling the two applications (sender, receiver) to be linked with this DLL to use this shared object for exchanging in between. As this object will be placed in a DLL, AFAIK, I need to export methods in this shared object to let sender and receiver applications to create this object and make calls. What is the best way to achieve this mechanism? I saw there is --cpp_out=dllexport_decl=__declspec(dllexport) option for protoc tool to export classes but it does not help for the inherited members, such as method: protoObject.SerializeAsString().

Re: [protobuf] Static allocation
I understand, but if one wants to keep a large persistent message allocated and walk over it frequently, there is a price to pay on cache misses that can be significant. In my situation I am maintaining a large persistent instance of a large message type that I used as a cached data set to compare runtime data with, and if it has changed, I want to re-send the parent message with only the changed bits across the network. This frequent operation can benefit from locality of reference if there was an option to generate the code statically, so that every lookup into the message doesn't have to involve a cache miss.

Obviously the repeater fields couldn't be fully statically allocated(unless you could provide the compiler with a max size), but it would be preferable to have the option to create messages with minimal dynamic memory impact. Is this possible in the current library? I'll assume you are talking C++. In this case, if you re-use a single message, it will re-use the dynamically allocated memory. This means that after the maximal message(s) have been parsed, it will no longer allocate memory. This is approximately equivalent to what you want.

[protobuf] Has anyone offered to write a ruby proto compiler, yet?
I'm making no promises, but if someone hasn't offered yet, what I have seen of protobuf has me very excited! I may make this one of my primary projects, to at the very least, write bindings to the C compiler in ruby, and eventually a pure ruby compiler. I intend to use protobuf as the primary serialization format for a P2P overlay network I've been working on for the last three years. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

There are a few Ruby implementations listed at http://code.google.com/p/protobuf/wiki/ThirdPartyAddOns - do any of those fit the bill?
