protobuf is a C++ library typically used in Utilities, Serialization applications. protobuf has no bugs and it has medium support. However protobuf has 2 vulnerabilities and it has a Non-SPDX License. You can download it from GitHub.

Protocol Buffers (a.k.a., protobuf) are Google’s language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find [protobuf’s documentation on the Google Developers site] This README file contains protobuf installation instructions. To install protobuf, you need to install the protocol compiler (used to compile .proto files) and the protobuf runtime for your chosen programming language.

            Until recently, the Go spec said that an interface defines a method set, which is roughly the set of methods enumerated in the interface. Any type that implements all those methods implements that interface.

            You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

            So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

            Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

            Handling enum value 0 in protobuf c++
            Asked 2022-Feb-21 at 14:33

            I'm working on a C++17 project that uses protobuf for data serialization, but I come across a problem.
            I tried to serialize an object defined in protobuf into std::string and the object has only one enum field, when accidentally the value of the field is set to 0, the function SerializeAsString() or SerializToString(std::string*) will return true but I always get an empty string. I checked out google api reference but got nothing helpful, can any one help me? I wrote some code to illustrate the problem.

            Suppose we want to define a kind of message in testProtobuf.proto

            Answered 2022-Feb-21 at 14:33

            This is actually not a problem at all since the parsing will work as expected because this is part of how protobuf handles default values:

            Also note that if a scalar message field is set to its default, the value will not be serialized on the wire.

            So because protobuf does not differentiate between a field being set to its default value and a field not being set at all, it simply does not serialize default values and your string is empty in this case.

            Also this does not apply for enums alone but for all scalar types:

            Asked 2022-Feb-03 at 10:18

            In our project, we have a data transfer object (DTO) class which is decorated with a [ProtoContract] attribute, and all of its members are public properties decorated with [ProtoMember] attributes - except that one of the members is a public field (by accident). Now we want to change the one public field into a property. Can this have an impact about the implicit protobuf contract?
