Description
`Apache ShenYu` is a Java native API Gateway for service proxy, protocol conversion and API governance. Currently, ShenYu has good scalability in the Java language.

`WASM`(WebAssembly) bytecode is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to leverage the common hardware features available on various platforms to execute in browsers at machine code speed.

`WASI`(WebAssembly System Interface) allows WASM to run in non browser environments such as Linux.

This plugin should base on [WasmPlugin](https://github.com/apache/shenyueventmesh/issues/4612), whcih means other languages, as long as their code can be compiled into WASM bytecode (such as Rust/golang/C++), can be used to write ShenYu plugins.

[kitex](https://github.com/cloudwego/kitex) is a Go RPC framework with high-performance and strong-extensibility for building micro-services.

Background

EventMesh currently has Eventing capabilities in the serverless field, but it should also improve and supplement the automatic expansion and contraction capabilities of eventmesh's own services and access services. This service is the coordinator responsible for automatically scaling services connected to EventMesh, supporting automatic scaling from 0 to n and scaling down from n to 0 based on event traffic or other user conditions.

Task

1. Discuss with the mentors what you need to do

2. Learn the details of the Apache EventMesh project

3. Implement the auto scaling service for eventmesh, which can support different auto scaling strategies by default, or knaive and keda can be selected as plugin services for automatic expansion and contraction of the service.

Recommended Skills

1. Familiar with go and K8S

2. Familiar with Knative\KEDA

Difficulty: Major
Project size: ~350 hour (large)

Mentor

Eason Chen, PMC of Apache EventMesh, You can find useful information [here](https://github.com/cloudwego/kitex/issues/1237).The usage documentation for WasmPlugin is [here](qqeasonchen, chenguangsheng@apache.org

Mike Xue, PMC of Apache EventMesh, https://shenyu.apache.org/docs/next/developer/custom-plugin/).

Relevant Skills
Know the use of Apache ShenYu, especially the wasm plugin.

What

https://datatracker.ietf.org/doc/html/rfc8617

https://arc-spec.org/

The Authenticated Received Chain (ARC) protocol provides an
authenticated "chain of custody" for a message, allowing each entity
that handles the message to see what entities handled it before and
what the message's authentication assessment was at each step in the
handling.

IE secured and standard Received headers.

Example:

            ARC-Seal: i=1; a=rsa-sha256; s=arcselector9901; d=microsoft.com; cv=none;

How

Implement a Mailet implementing ARC

Implement a Matcher validating ARC

Documentation (README)

If applicable, parsing ARC records shall be done as a separate maven module.

Definition of done

• Absence of ARC headers shall be nicely handled
• Failed ARC shall be rejected
• Able to send email to gmail (validates ARC)
• Passes the ARC test suite https://github.com/ValiMail/arc_test_suite
• Apache james registered on https://arc-spec.org/?page_id=79

GSOC notes

Presenting a 1 week POC on the topic (as a separate mailet) would greatly improve the submission.
