QUESTION
Consider the following protobuf message declaration:
...ANSWER
Answered 2021-Oct-28 at 11:57If you aren't using the JSON variant, then names aren't used at all in the payload, so yes technically it is perfectly legal to reuse names; however: this might lead to unnecessary problems with existing code - depending on existing code and language / framework specific rules, and could cause confusion. Since that is avoidable, I would advocate using a name like origin_airport_code, or similar.
(The point I'm making here: any code that used the old field probably needs attention; I can see some scenarios where the existing code might still compile after the change, but mean something different, and therefore introduce a bug that would have been avoided if you'd changed the name and forced every usage to be visited)

I'm trying to write a parser for protobuf3 using the grammars from https://github.com/antlr/grammars-v4/blob/master/protobuf3/Protobuf3.g4.
and I'm trying to deal with the _type declaration in my grammar:

QUESTION
Im trying to build my proto files in a way that what proto files I include is publicly available when I build to the various languages. I have tried import public "webrtc/signaling.proto" and it removes the "is not used" message, but the message type of RTCMessage is still not included in my c# build Mafia.cs when I use the command ./protoc.exe -I=G:/MafiaProject/MafiaProtobuf/protofiles --csharp_out=G:/MafiaProject/MafiaProtobuf/csharp_out G:/MafiaProject/MafiaProtobuf/protofiles/mafia.proto but seemingly is included when I build for go.
ANSWER
Answered 2020-Dec-06 at 11:26You should pass all the path of your proto files as input argument to the protoc command, as example:
protoc -I="."/MafiaProject/MafiaProtobuf/protofiles --csharp_out="."/MafiaProject/MafiaProtobuf/csharp_out MafiaProject/MafiaProtobuf/protofiles/.proto MafiaProject/MafiaProtobuf/protofiles/webrtc/.proto

QUESTION
My company is consider using protobuf3 as an message communication schema between our many microservices, and we struggle with find a solution for information lost when handling a message that transfer between more then 2 services and have more then one version, and I'll explain by writing an example:
I have three microservices, A,B,C that communicate with each other using the same schema:
...ANSWER
Answered 2020-Nov-12 at 08:32I found this paragraph on google's protobuf3 documentation:
Originally, proto3 messages always discarded unknown fields during parsing, but in version 3.5 we reintroduced the preservation of unknown fields to match the proto2 behavior. In versions 3.5 and later, unknown fields are retained during parsing and included in the serialized output.
so using protobuf3.5+ was the answer for me

Install protobuf3
You can use protobuf3 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
