Update protoc-gen-grpc-java dependency to > v1.26.0 to be able to build in ARM64

[yagop]

1. What did you do?

Trying to build java-tron

2. What did you expect to see?

A java-tron builded

3. What did you see instead?

 > Could not find protoc-gen-grpc-java-linux-aarch_64.exe (io.grpc:protoc-gen-grpc-java:1.9.0).13 actionable tasks: 13 executed

Problem

You are using old version of protoc-gen-grpc-java which lacks arm64 binaries. See protoc-gen-grpc-java-1.9.0-linux-aarch_64.exe is missing from https://repo.maven.apache.org/maven2/io/grpc/protoc-gen-grpc-java/1.9.0/ .

Asking

Update protoc-gen-grpc-java to >= v1.26.0 in order to be able to build java-tron in arm64.

Hi, please provide detailed information, thanks. which operation system and device do you compile the java-tron project, and do you use any IDE or compile tool to compile the project?

[yagop]

which operation system and device do you compile the java-tron project

I'm using Ubuntu 18.04.6 Docker for ARM64

do you use any IDE or compile tool to compile the project

I'm not using any IDE. Just ./gradlew build -x test

[vivian1912]

Currently ARM64 architecture is not supported by java-tron, but it is under planning，so now I will suggest to build and run fulllnode under intel or AMD architecture, and for ARM64 support, please pay attention to the announcement or release of java-tron. Thanks.

[yagop]

To support ARM64 you need to upgrade protoc-gen-grpc-java which uses a very old version with CVE, see https://mvnrepository.com/artifact/io.grpc/protoc-gen-grpc-java/1.9.0

I need to run java-tron in my machine which is an ARM64. I would be happy to test for you if you do the changes.

[vivian1912]

Thanks for your information. but for supporting ARM64 architecture, It maybe not just a dependent library needs to be upgraded, but JDK or DB and so on. and it is under planning. So now it is recommended to build on an alternative machine which based on intel/AMD. Or if you're interested on this, you can try to modify the code to meet the requirement. Thanks.

[yagop]

That library is a block, there might be others, you can try to build to arm64 with this Dockerfile:

[vivian1912]

Thanks for your information. Because it has already under planning, so we will keep you informed if there's any progress

[yagop]

Any updates on this?

[forfreeday]

@yagop
A docker mirror supporting the ARM architecture is already in development

[yagop]

Any update on this?

[forfreeday]

The arm approach to docker images is not supported at this time

[yagop]

Update protoc-gen-grpc-java please

[andelf]

For compatibility with the mainnet, java-tron can only be run on x86-64 platforms(and jdk8). It requires 8087 float instructions.

[yagop]

It requires 8087 float instructions.

What instructions? AFIK Tron is written in pure Java so should be able to compile for the ARM JVM.

[andelf]

@yagop That's the hidden part of JVM.

In theory
If > 1/3 of the bp nodes use a non-java8 or non-x86 machine, with a carefully constructed transaction, the whole consensus might stop.

[yagop]

Please stop saying not verified unrelated justifications.

I’m only asking you guys to update protoc-gen-grpc-java which is using old version which is vulnerable.

@vivian-kang and @forfreeday stated this was underplaying half a year ago but no progress was made

[ethan1844]

Thanks for your contribution to java-tron, this issue will be closed as no update for a long time.

Please feel free to re-open it if you still see the issue, thanks.
