yuluo-yx opened a new issue, #4415: URL: https://github.com/apache/rocketmq-dashboard/issues/4415
### Before Creating the Bug Report - [x] I have searched the [open issues](https://github.com/apache/rocketmq-dashboard/issues) of this repository and believe that this is not a duplicate. - [x] This is a defect in RocketMQ Studio, not a usage question and not a defect in another Apache RocketMQ repository. - [x] I can reproduce this on the current `master` branch, or I have stated the exact version I am running below. ### Studio Version branch: `master` This issue is migrated from PR #4090, which was based on the former `rocketmq-studio` branch. The branch switch notice #4379 states that `master` now points at the same Studio commit graph. ### Runtime Environment See the migrated verification and reproduction notes below. The original fix was developed and verified locally before the branch switch. ### Connected RocketMQ Cluster See the migrated reproduction notes below. This bug is in RocketMQ Studio behavior. ### Build Toolchain See the migrated verification notes below. ### Describe the Bug 修复周期维护窗口在夏令时切换时错误延迟或提前发送告警的问题。 ### Steps to Reproduce The previous pull request body below includes the reproduction or scenario that motivated the fix. ## 变更目的 修复周期维护窗口在夏令时切换时错误延迟或提前发送告警的问题。 - 纽约每日 02:30–04:00 的窗口在 2026-03-08 应解析为 03:30–04:00；旧实现错误延长到 05:00。 - 首个窗口明确选择秋季重复时段的 `-05:00` 偏移时，旧实现重新解析为 `-04:00`，导致有效窗口被跳过。 ## 修改内容 首个窗口保留请求指定的确切起止瞬间；后续窗口从名义当地时间分别解析开始与结束边界。保留原有后续重复时段的偏移选择规则、星期限制和周期截止时间。没有新增依赖、配置或数据库字段。 13 个时间边界测试覆盖一小时／半小时缺口、秋季重复时段、跨日每周窗口与亚秒边界；6 个服务组合测试覆盖创建、UTC 存储、维护窗口计算和三种通知渠道入队时间。新增中文行为与回滚说明。 ## 验证 基线：`d6dee7d7ccfcf4886f02466ec51452a6928b2cc8`，Java 21。 - 三个最小复现在旧实现上全部失败。 - `mvn -B -ntp -Dtest=AlertSilenceScheduleTest,AlertSilenceDstTest,AlertSilenceServiceTest,RecurringSilenceNotificationTest,NotificationOutboxServiceTest test`：65 个测试通过，Checkstyle 通过。 - `mvn -B -ntp -DskipTests package`：构建通过。 - JaCoCo：修复类行覆盖率 35/37（94.6%），分支覆盖率 38/44（86.4%）。 - 全量后端测试：2,110 项，3 个失败。已在完全未修改的上游基线复现相同失败：`AuthCorsIntegrationTest` 两项、`AliyunInstanceProviderTest#getGroupProgressShouldMapLagRowsTest` 一项。 - `git diff --check`：通过。4 个文件，416 行新增、18 行删除。 未运行真实集群 E2E、压力和混沌测试。本次时间计算仍只检查最多 8 个候选日期，通知测试不向外发送消息。上游既有依赖漏洞尚未由本 PR 处理，不能据此声称项目级漏洞门槛通过。 按贡献指南 #2107 将同一维护窗口语义的缺陷与验证合并。已核对 #3070 的原始功能、#3303 的七天周窗口修复和 #3415 的配置边界测试，本次处理的夏令时缺口与明确偏移不与其重复。 本地执行验证，提交使用 `[skip ci]`，不会自动运行 `push`／`pull_request` 工作流。无迁移，直接替换；回滚本提交即可。 ### What Did You Expect to See? RocketMQ Studio should preserve the behavior described by the fix and avoid the faulty behavior described above. ### What Did You See Instead? The faulty behavior described above occurs without the migrated fix. ### Additional Context - Replaces PR #4090: https://github.com/apache/rocketmq-dashboard/pull/4090 - Branch switch notice: #4379 - Target branch for the new PR: `master` ### Are You Willing to Submit a Pull Request? - [x] Yes, I am willing to submit a pull request. -- This is an automated message from the Apache Git Service.
