Add a plugin that supports the Solon framework. by xsShuang · Pull Request #697 · apache/skywalking-java · GitHub

Add an agent plugin to support

Add a test case for the new plugin, refer to the doc
Add a component id in the component-libraries.yml
Add a logo in the UI repo

What is this? I think we didn't discuss about this part.

Controlling which paths require plugins through environment variables, so I used this class, which comes from this project https://github.com/apache/skywalking-java/blob/main/apm-sniffer/optional-plugins/trace-ignore-plugin/src/main/java/org/apache/skywalking/apm/plugin/trace/ignore/matcher/FastPathMatcher.java

Ignore plugin is reading configurations from the agent folder, why do ou need that for Solon?

solon 不需要他，是我自己想添加这样一个功能。尽管有 trace-ignore-plugin 这个插件，但我认为这个插件是在链路追踪后写入数据时阻止忽略的数据写入，而我希望的是插件在生效时，直接过滤排除的 url 请求地址

这个类用进行 URL 地址匹配，从而实现排除某些不需要链路追踪 URL 的目的

Please keep in English in GH discussion.

I don't think ignoring should be implemented by a specific plugin of a specific framework.

Please remove this part.

AFAIK, the existing ignore plugin could collaborate with your plugin automatically.

Also, I can see you didn't follow the document to add relative plugin tests.

Notice, as we are only hosting your codes, to guarantee it works for end users, we need you to finish plugin tests and verify the data.

抱歉，我没有linux和mac环境来运行自动化测试，但我编写了我提交插件的测试文件，请问有其他的办法可以进行测试吗？

Please use English on Github.

You could use VM or something to run the tests.

Please add it into CI control file to make sure it runnable, and attach your local test results.

Meanwhile please be clear about supported versions in docs and test supported list.

We should not support only one version. You could verify all supported versions(patch versions), and list all minor versions, one patch version per minor version(such as 2.8.3 for 2.8.x, 2.7.3 for 2.7.x).

There is no Solon component related. What is the meaning of your tests?

Sorry, this isn't the final code, I just wanted to get a different computer to continue with the code

Please follow other comments to fix these

GHA control file needs to add this new test case.
Docs should be updated. changes.md and supported-list.md
Verification version list.

Any update?

Sorry, it's been a busy day. I'll take care of it tomorrow.

Verification version list.

I have submitted the appropriate documents as per your instructions, please help me to confirm whether it is correct or not, thank you!

Resolve the conflicts, then I could make CI works to verify.

# Conflicts: # CHANGES.md

Please run tests locally, rather than costing us too much on running repeatedly.

I didn't follow my comments. 2.7(per minor version) and 2.8 should keep one version only.

Sorry, my English is really bad and I have to rely on translation software, which leads to a lot of places that I can't fully understand.

CN slack is there. If you have doubts, ask there.

None of entry spans have reference verifications, this test scenarios can't prove the tracing continues.

Solon is a RPC framework AFAIK, your test doesn't cover an important part.

Sorry, I can't fully understand the meaning of automated test scripts. I wrote this script with reference to spring. From the results I get from running it, I think I can get the link tracing information

If no reference, I can't see how it links.

You should check the segments of traces, and understand the data.

As I have explained, we don't maintain the plugins, but host for you(for example). After this, I can't ask you every time when someone submitted an issue/discussion. So, the best way is, test scenarios themselves can prove it works as expected.

The comments/descriptions should be polished. Refer to the above one.

Why do you accept the error unprocessed? I think that is far away of the purpose of tracing. Error codes are important.

I have no control over when the user handles exceptions

My question is about this config. Why do we need this config?

This configuration is where I need the user to tell me if he handled the exception, and if he did, I'll set up exception logging for him and use the status code after he handled it

If you want to process that, why don't you create an interceptor for filter(s)? It should be easy too.

I spoke with the solon author and he thinks that adding a filter customised for tracking doesn't make sense in the framework and that there should be plugins for that. But I want to make tracking available to users using solon without having to change any code.

Add plugin configuration and instructions

This config field doesn't exist in the codes. Why it is here?

Again, you should not collect all headers. All collected things should be very specific.

Header usually carries auth token, this is auto collecting is dangerous and could cause sensitive data leak.

Inceptor method should not be defined by the configurations. This is a kind of config abuse.

You are changing the whole file? Please don't do this.

These two don't make sense. And the comments are not helpful.
Even you are not good at English, there are many AI tools could help you polish that.

Besides the comments, I am highly concerned about these two configurations. Please explain more clearly.
I never saw a framework plugin did this. The error code process should be very simple and straight forward.

Add plugin configuration and instructions

Please use v2 plugin APIs for better performance, and don't use runtime context to collaborate inside an interceptor.

Modified to V2 version of the interceptor

Remove the code that collects all headers by default

Suggested change

      
                    String operationName = "Solon:" + ctx.method() + ":" + ctx.path();
          
                    String operationName = ctx.method() + ":" + ctx.path();

The operation name of the span should be framework stack irrelevant. And you need to change test cases accordingly.

You should control header by key list, because every key has a length limitation by HTTP. Once the number of keys is limited, we don't need to worry about overload.

Dev

lgtm, thanks for your patience.
