Hello, For ASoC 2020 I would like to improve the C++ Version of Sentinel. I'm trying and testing the whole project. There are a few questions:
How to debug the codebase?
Eric Zhao
@sczyh30
You may refer to the README to build the project and run the demo.

@sczyh30
For all ASoC applicants: don't forget to prepare a demo (code snippet) to show your ability regarding your idea and proposal :)

@RonnieGandhi
Hi @sczyh30 I am Ronnie Gandhi a Computer Science undergrad from IIT Roorkee I have previously done GSoC19 and have done an intern in 2019 at Microsoft and I am currently also interning there. I am interested in working on the C++ sentinel project and I have cloned , built and ran the https://github.com/alibaba/sentinel-cpp repo. Please inform me about what all things are to be done since it looks like this project was there in SoC2019 as well
Eric Zhao
@sczyh30
For Sentinel C++ you'll need to implement frequent parameter flow control (based on sliding window, token bucket and eviction mechanisms like LRU and LFU) and token client for distributed rate limiting. You'll also need to abstract Sentinel APIs for C projects.
Eric Zhao
@sczyh30
For all potential ASoC applicants: the deadline of proposal is June 30th. Don't forget to prepare your resume, proposal as well as the demo that can show your ability regarding your ideas.

Hi community, Sentinel Go 0.4.0 release!In this version, we've brought flow control capability for frequent ("hot spot") parameters, which enables detecting top-N visiting parameters and perform fine-grained rate limiting for every "hot" values (or for some specific values). Currently Sentinel Go supports basic numeric types (various int/uint/float types), bool type and string type. Release notes: https://github.com/alibaba/sentinel-golang/releases/tag/v0.4.0

Thanks for the contributors: @louyuting, @sczyh30

A应用调用了C的dubbo接口,B应用调用了C的dubbo接口,只限制A应用调用C,这个应该怎么配置?同一应用内的,已经知道怎么配了。

After I modify rules in dashboard, all rules of the corresponding application are cleared. The log shows that the resource name was not received(is null) in the dynamicsentinelproperty, so the rule was rejected. I want to know where the configuration is wrong, thx
You may upgrade your fastjson dependency.

Hi 各位大佬好,sentinel 集成apollo 持久化我有一个疑问,客户端集成sentinel apollo database ,我那个客户端本身就集成了Apollo appId 为gateway ,现在我需要新创建一个apollo-sentinel ,然后客户端监听apollo-sentinel 上的变化,但是这时候项目就有两个appId 了,假如我设置了System.setProperty("app.id","apollo-sentinel") 另外一个appId gateway 可以被监听到吗?
