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:

protobuf-net: properties versus fields

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? (We want to avoid breaking changes, and I suppose that this change is non-breaking, but I want to be sure.)

ANSWER

Answered 2022-Feb-03 at 10:18

Yes, that's absolutely fine; protobuf-net won't care, and the serialized payload will remain identical.

Missing bounds checking elimination in String constructor?

Asked 2022-Jan-30 at 21:18

Looking into UTF8 decoding performance, I noticed the performance of protobuf's UnsafeProcessor::decodeUtf8 is better than String(byte[] bytes, int offset, int length, Charset charset) for the following non ascii string: "Quizdeltagerne spiste jordbær med flØde, mens cirkusklovnen".

I tried to figure out why, so I copied the relevant code in String and replaced the array accesses with unsafe array accesses, same as UnsafeProcessor::decodeUtf8. Here are the JMH benchmark results:

the database has a table tiles which is full of blobs
the blobs are binary with gzip signatures

Support

This module (github.com/golang/protobuf) contains Go bindings for protocol buffers. It has been superseded by the google.golang.org/protobuf module, which contains an updated and simplified API, support for protobuf reflection, and many other improvements. We recommend that new code use the google.golang.org/protobuf module. Versions v1.4 and later of github.com/golang/protobuf are implemented in terms of google.golang.org/protobuf. Programs which use both modules must use at least version v1.4 of this one. See the developer guide for protocol buffers in Go for a general guide for how to get started using protobufs in Go. See release note documentation for more information about individual releases of this project. See documentation for the next major revision for more information about the purpose, usage, and history of this project.
