Support aarch64 CPU architecture in gRPC extension code generation

[jamesnetherton]

Description

It'd be useful if the gRPC extension protobuf code generation steps could work with aarch64.

See this reported issue in the camel-quarkus project apache/camel-quarkus#2762.

Implementation ideas

Upgrade protoc to 3.17.3 as aarch64 seems to be supported:

we need to see if vertx-grpc is compatible with this

[cescoffier]

@pmlopes do you know with Vert.x gRPC works with aarch64?

[pmlopes]

@cescoffier while this is totally possible:

vert-x3/vertx-grpc#103

Netty versions are still preserved and tests pass, I can only assume that you will be able to compile proto files as protoc now offers a native aarch64 binary and the jprotoc/canteen plugins we use to run our templates from java also seem to offer thse binaries:

https://repo1.maven.org/maven2/com/salesforce/servicelibs/canteen-bootstrap/1.1.0/canteen-bootstrap-1.1.0-osx-aarch_64.exe

I don't have access to this hardware setup so I cannot be 100% sure that after merging the PR you can bump the vert.x dependency and close this issue.

[michalszynkiewicz]

So, protoc is indeed there but protoc-gen-grpc-java is not...
I don't have the hardware to check if it's possible to use some other binary for protoc-gen-grpc-java with e.g. osx-x86_64...

[michalszynkiewicz]

People write this is possible with Rosetta.
This PR: #18992 upgrades grpc to the version used by vertx-grpc and allows to override the os classifier, so in case of M1+rosetta, should allow mac users to use osx-x86_64 binaries, if I understand it correctly.

[michalszynkiewicz]

I don't want to close this issue yet, let's close it when we have a proper fix (when protoc-gen-grpc-java is released for osx-aarch64)

Hello @michalszynkiewicz, Mandrel has aarch64 builds available on https://github.com/graalvm/mandrel/releases/tag/mandrel-21.3.0.0-Final

Is this issue actually resolved or does it make sense to include these tests in aarch64 Quarkus TS runs?

[michalszynkiewicz]

It is nearly resolved ;)

The only thing that's not great is that building Conscrypt is required for some use cases, I'm guessing TLS ones. See #21417

[cescoffier]

Fixed.
