Hello, My executable is composed of multiple .proto files, some of them importing others. I would like the executable to communicate with a generic program (Which is compiled once and does not change), using protobuf messages. So, I need the generic program to get the descriptors of messages used in the communication at run-time, from my executable. I understand that to do this, I need the executable to create a FileDescriptorSet containing all the files needed to describe a certain message, serialize this set, pass it to my generic program, which will then create a descriptor pool and feed it with the deserialized FileDescriptorSet. Now that I have this populated pool, the generic program can find any descriptor by it's name, as communicated from the executable.
My question is: Is there a method to automatically create the file descriptor set of all files used inside a given application, in proper topological order (i.e. imported files appearing before files depending on them) ? I know that protoc can create such a set, but this set reflects the set of files used in a single protoc run, and my application has multiple files. I thought about iterating all descriptors found in the generated_pool, gathering the set of files, sorting them and creating this set, but there is no way to iterate all descriptors in the pool. It seems to me that in order to gather all file descriptor protos used in my executable, I need to manually define a single .proto file importing all other files, but I do not like this idea because it means taht every time I add a new .proto file to my application, this 'master proto' file needs to be updated. (Yes, the build system could do it automatically). Is there a better way ? Thanks, Oren. -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
