The exception information of the previous slice execution is not cleared

## Bug Report If the current task fails to execute, even if the next execution is successful, the event tracking will get the exception information of the previous execution failure....

If a backend is specified, an error in the `preCheck` during deletion will result in the backend becoming null

Due to the fact that the errors returned by `preCheck` during deletion are ignored, the processing logic for deletion is executed directly. ```go // pre-check Configuration if err := r.preCheck(ctx,...

Have configuration resources A and B that both configure the same backend，when configuration resource A is deleted, if there are other configuration resources like B referencing this backend, the terraformDestroy method should not be executed.

When we try to specify a backend for a configuration resource, due to the controller not performing duplicate validation, suppose we have configuration resources `A` and `B` that both configure...

Before deleting, check if there are other configurations using the same backend. If there are, do not proceed with the deletion

ChatTCP是一款TCP数据包分析工具，致力于简化TCP分析，让TCP分析变得跟看聊天记录一样简单。 官网地址：[chattcp.com](https://chattcp.com) 这是一款macOS app，上架Mac App Store。核心功能免费。核心功能包括：自动识别出所有TCP连接，按连接以聊天式的人机交互分析连接往返的TCP数据包，提供映射到TCP协议数据结构的视图，提供自动分析延迟、丢包、重传情况以及是否完成握手、是否出现强制断连情况的诊断功能。 Wireshark很强大，但对于新手来说入门门槛太高了。ChatTCP很适合新手入门，再过度到Wireshark。ChatTCP的核心功能满足用户用来学习掌握TCP协议，提供了TCP三次握手、四次挥手的案例供学习，通过实战学习TCP协议效率更高，比看图片动图都容易理解。 除了app，还提供在线版，在线版免费且无广告，但只有核心功能，只适合用于学习用途。 在线版地址：[online.chattcp.com](https://online.chattcp.com)

Reactor项目中使用Sentinel偶尔会出现Context0#put空指针异常

4

WebFlux项目中导入sentinel-spring-webflux-adapter:1.8.0适配模块，项目每天都有好几个NPE，报错内容如下： ``` Caused by: java.lang.NullPointerException: value at java.util.Objects.requireNonNull(Objects.java:228) at reactor.util.context.Context0.put(Context0.java:30) at com.alibaba.csp.sentinel.adapter.reactor.SentinelReactorSubscriber.currentContext(SentinelReactorSubscriber.java:70) ``` 对应的源码应该是这一行 ```java return actual.currentContext() .put(SentinelReactorConstants.SENTINEL_CONTEXT_KEY, currentEntry.getAsyncContext()); ``` 从异常栈信息看，应该是`currentEntry.getAsyncContext()`这句返回了null，但不知为何会出现null

项目源码：https://github.com/chattcp/chattcp-idea-plugin 插件安装使用教程：https://chattcp.com/download/intellij-plugin 功能特性： 🔍 在IntelliJ IDEA中实时捕获和查看TCP数据包 💬 聊天式数据包展示（客户端/服务器对话） 🔌 支持数据包HTTP/WebSocket协议解码 📥 导出捕获的数据包为PCAP文件，便于进一步使用Wireshark/ChatTCP等工具分析 预览:  工具非常有助于平时开发接口调试，能够直接从四层协议看问题，而不仅仅是七层。因为有些情况从七层协议分析问题是很难发现问题的，比如SSE为什么实现不了打字机效果，看起来是卡到最后一次性响应的，但从四层能看出数据包是连续发送的。 支持直接抓127.0.0.1的数据包。
