I'm learning Go 1.18 generics and I'm trying to understand why I'm having trouble here. Long story short, I'm trying to
Unmarshal a protobuf and I want the parameter type in
blah to "just work". I've simplified the problem as best I could, and this particular code is reproducing the same error message I'm seeing:

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

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...

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.
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:

It happened the same to me last friday. I think it has something to do with Cuda instalation in Google Colab but I don't know exactly the reason
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.)
ANSWERAnswered 2022-Feb-03 at 10:18
Yes, that's absolutely fine; protobuf-net won't care, and the serialized payload will remain identical.
I'm running Kafka schema registry version 5.5.2, and trying to register a schema that contains a reference to another schema. I managed to do this when the referenced schema was in the same package with the referencing schema, with this

First you should registrer your other proto to the schema registry.

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

To measure the branch you are interested in and particularly the scenario when
while loop becomes hot, I've used the following benchmark:
For a map tiling project (think google earth) I have a
.mbtile file that I know nothing about other than it has a lot of data about cities on the planet. I've been picking at it for a couple days and have found out the following:
- the file is a sqlite database
- the database has a table
tileswhich is full of blobs
- the blobs are binary with gzip signatures
- after unzipping, the result is a protocol buffer
I haven't worked with protobuf much so I'm getting a crash course. I took the unzipped binary and with
protoc --decode_raw received the following
