@Scarb 好像有点理解了, 所有的消息会广播给所有的消费组, 但是组内会直接拉取全部并过滤, 所以如果我想要的是一部分消费 t1, 一部分消费 t2, 搞两个消费组就行, 我之前以为消息只回传一次, 一边消费完了就没有了, 其实如果新建消费组订阅的话, 消费位点会从 0 开始, 这样理解对吧

@onepunch 我就是按文档写的呀, 按我的理解, 我生产了一条 tag=t1 的消息, 然后我订阅 tag=t2 的消息, 这个消息不应该被消费者收到, 我也确实没有收到, 但是这条消息同时也应该留在队列里面, 不应该是被消费的状态, 但是我这里确实显示被消费了, 所以百思不得其解

这里提到一个商业库 ExtenXLS 好像可以, 考虑吗?

经过几天研究, 可能搞定了, 主要还是靠 pmset -g log 分析日志, 看 WakeRequest 都是些什么东西

一开始是 CSPNEvaluation, 反正是跟 PowerNap 有关的, 想办法改配置文件禁用掉了, 不行

后来是一些 Scheduled power events, 用 sudo pmset schedule cancelall 全部取消掉, 还是不行

再后来发现第二天所有的计划任务又重新冒出来了, google 之后, 先全部 cancel 掉, 然后 sudo chflags schg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist 把配置文件设为只读, 貌似可以了

现在过去 2 天都没有半夜耗电的毛病了, 感觉差不多应该是好了, 真是艰难啊

昨天晚上观察了一下, 问题依旧, 早上起来只剩 50%电, 观察活动监视器的能耗没有结论, 因为这个就像是普通的唤醒电脑的样子, 都是一些正常的 APP 的待机能耗使用, 整个看上去就像是半夜 2 点电脑被唤醒打开, 然后 APP 正常待机工作的感觉, 但是实际上是全程不插电, 没有任何外接, 合盖的情况下发生的, 完全搞不懂了, 看日志的话, 只能看到是 0 点的时候进入睡眠, 但是只计划睡眠 2 个小时, 然后两个小时后 DarkWake from Deep Idle, 时间是 6 小时, 反正搞不懂这些计划安排是怎么来的, 头大

我没有接任何外设显示器之类的, 和这些无关, tcpkeepalive,powernap 原先设定是 1, 感觉关系应该不大, 1 代表接电源才启用, 我这个是没接电源就耗电的, 反正这两个先设成 0 试试

倒是那个音频的东西是有可能的, 通过 pmset -g assertions 能看到 PreventUserIdleSystemSleep 是 1, 是由火狐进程触发的 BuiltInSpeakerDevice 的 preventuseridlesleep, 退出火狐就没了, 还有之前也装过 blackhole 的虚拟声卡, 现在我也卸了

该做的都做了, 就看会不会复发了

@kafkaonsea @arcaitan 谢谢, 这两个我都试一下, 观察几天看看效果

可选的舍入方式有 6 种, 常说的四舍五入对应 infinity 这种, 在 c#里面也叫 AwayFromZero, 但是这个会有统计学误差, 所以另一种常见的舍入方式是 even, c#里叫 ToEven, Java 里叫 HalfEven, 也就是上面有人提到的银行家舍入

不同的语言, 不同的函数使用的舍入规则都是不一样, 比如 toFixed 和 Math.round 用的就是不一样的, MySQL 的 decimal 和 float 规则不一样, 如果追求 100%精确的话就得去看文档他们用的到底是哪一种方案, 或者 Java/c#这种可以有选项让你控制使用哪一种舍入规则
