Overview

I think it's time to start iterating on hashicorp/consul#11536 . Since, I've gathered some feedback from folks that we can implement.

Suggestions

Let's look at an errored check:

重现步骤：
1.运行的demo如下，使用 AcknowledgmentCallback.noAutoAck() 关闭自动ack，打印之后再 ack

 @Bean
    public ApplicationRunner poller(PollableMessageSource dest1In) {
        return args -> {
            while (true) {
                if (!dest1In.

Right now, whenever Zenmap crashes, it gives the user a stack trace and asks the user to send it to the Nmap dev list. So we get a flood of emails (most of which aren't even allowed through moderation) which often contain just a stack trace with no subject line or any explanatory text in the message body.

目前在代码里有两次计算 ServiceInstanceRevision 的方法：

1. 消费 comRevisionCh 异步计算
2. ServiceInstancesCache 发现流程中同步补偿计算
   这两个地方使用的 service 信息不一致，前者是 revision，后者是 id

// processRevisionWorker 处理revision计算的函数
func (nc *NamingCache) processRevisionWorker(req *revisionNotify) bool {
	if req == nil {
		log.CacheScope().Errorf("[Cache][Revision] get null revision request")
		return false
	}

	if req.servi
