From e12655fc3066c24b692c512f9dba1f74511ef03b Mon Sep 17 00:00:00 2001 From: Ivy233 Date: Tue, 11 Aug 2026 22:24:29 +0800 Subject: [PATCH] fix: move notification expire timer to the bubble frontend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The notification expire timer previously ran in the notification server (worker thread) and was started when the notification was received, so a notification waiting in a long display queue could expire before its bubble was shown. The timeout is now owned by the bubble frontend and only starts once the bubble is actually displayed. 1. Add an ExpireTimer process-wide singleton that tracks each notification id's deadline with one shared single-shot QTimer. It exposes operation-based APIs (start/stop/setBlockedId) instead of lower-level get/set ones and derives the effective timeout from the entity internally, so no QTimer is allocated per notification and nothing leaks on expiry. stop() suspends a countdown by remembering its absolute deadline and start() resumes it, so a notification moving between the bubble and the staging area never restarts its countdown. 2. BubbleModel starts the expire timer when a bubble is shown (insert/replace) using the client expireTimeout (0: never expire, -1: 5000ms default, Critical urgency: never expire). On expiry it emits bubbleExpired(id, bubbleId). setBlockedId pauses/resumes the countdown so hovering keeps the bubble on screen, keeping the 1s grace after unhover. 3. BubblePanel closes the expired bubble and calls notificationClosed(id, bubbleId, Expired) on the server. 4. The notification center staging model reuses the same timer so notifications shown in the staging area also time out. 5. Make NotificationManager::notificationClosed idempotent: a notification is tracked by both the bubble and the staging expire timers, so the close is reported only while the entity still exists, preventing a notification from being closed twice. Critical notifications never expire on their own, enforced both when computing the frontend timeout and on the server. 6. Remove the server-side timeout bookkeeping: setBlockClosedId, pushPendingEntity, onHandingPendingEntities, removePendingEntity and the pending-timeout QTimer. 7. Expose BubbleItem::entity() and NotifyEntity::timeout()/urgency() for the frontend timeout computation. 8. Remove the obsolete SetBlockClosedId tests. Log: Fixed notifications expiring before their bubble was displayed. Influence: 1. Send several notifications at once and verify each bubble stays for the full expire timeout. 2. Verify critical notifications and expireTimeout 0 never close. 3. Hover a bubble and verify it does not expire, then closes 1s after unhover. 4. Verify an expired notification is closed only once and moved to the notification center, and the DBus NotificationClosed(Expired) signal is emitted once. 5. Open the notification center and verify staged notifications expire after their timeout and leave the staging area. 6. Run the notification server unit tests. fix: 将通知过期计时迁移到气泡前端 通知过期计时此前在通知服务器（工作线程）中运行，收到通知时即启动，导致 长显示队列中的通知可能在显示前就已过期。现将超时逻辑交由气泡前端持有， 气泡真正显示后才开始计时。 1. 新增 ExpireTimer 进程级单例：用一个共享的单次 QTimer 管理每个通知 id 的 过期时间，提供 start/stop/setBlockedId 操作化接口，并由实体内部计算有效 超时时间，不再为每个通知分配 QTimer，到期后也不会泄漏对象。stop() 通过 记住绝对截止时间挂起倒计时，start() 恢复它，因此通知在气泡与暂存区之间 切换时不会重新计时。 2. BubbleModel 在气泡显示（插入/替换）时根据客户端 expireTimeout 启动过期 计时（0：永不过期，-1：默认 5000ms，Critical 优先级：永不过期），到期时 发出 bubbleExpired(id, bubbleId)。setBlockedId 暂停/恢复计时，使悬停时 气泡不关闭，并保留取消悬停后 1s 缓冲。 3. 到期后 BubblePanel 关闭气泡并调用服务器 notificationClosed(id, bubbleId, Expired)。 4. 通知中心暂存模型复用同一计时器，暂存区展示的通知同样会超时。 5. 使 NotificationManager::notificationClosed 幂等：同一通知会被气泡与暂存 模型的过期计时同时跟踪，因此在实体仍存在时才上报关闭，避免通知被关闭 两次。Critical 通知永不自动过期，前端超时计算与服务端均强制执行。 6. 移除服务端超时簿记：setBlockClosedId、pushPendingEntity、 onHandingPendingEntities、removePendingEntity 以及 pending-timeout 定时器。 7. 为前端超时计算暴露 BubbleItem::entity() 与 NotifyEntity::timeout()/ urgency()。 8. 移除过时的 SetBlockClosedId 测试。 Log: 修复通知在气泡显示前就过期的问题。 Influence: 1. 一次性发送多条通知，验证每个气泡都能保持完整的过期时间。 2. 验证 Critical 通知与 expireTimeout 为 0 的通知永不过期。 3. 悬停气泡验证其不关闭，取消悬停 1s 后关闭。 4. 验证过期通知只被关闭一次并进入通知中心，DBus NotificationClosed(Expired) 信号只发送一次。 5. 打开通知中心，验证暂存区的通知到期后超时并移出暂存区。 6. 运行通知服务器单元测试。 PMS: BUG-372279 --- panels/notification/CMakeLists.txt | 2 + panels/notification/bubble/bubbleitem.cpp | 5 + panels/notification/bubble/bubbleitem.h | 1 + panels/notification/bubble/bubblemodel.cpp | 50 +++-- panels/notification/bubble/bubblemodel.h | 12 +- panels/notification/bubble/bubblepanel.cpp | 10 +- .../center/notifystagingmodel.cpp | 20 +- panels/notification/common/expiretimer.cpp | 191 ++++++++++++++++++ panels/notification/common/expiretimer.h | 76 +++++++ panels/notification/common/notifyentity.cpp | 10 + panels/notification/common/notifyentity.h | 4 + .../server/notificationmanager.cpp | 132 +----------- .../notification/server/notificationmanager.h | 9 - .../server/notifyserverapplet.cpp | 8 +- .../notification/server/notifyserverapplet.h | 1 - .../server/notifyserverapplet_test.cpp | 22 -- 16 files changed, 371 insertions(+), 182 deletions(-) create mode 100644 panels/notification/common/expiretimer.cpp create mode 100644 panels/notification/common/expiretimer.h diff --git a/panels/notification/CMakeLists.txt b/panels/notification/CMakeLists.txt index b7c6414eb..f7a60ff03 100644 --- a/panels/notification/CMakeLists.txt +++ b/panels/notification/CMakeLists.txt @@ -22,6 +22,8 @@ add_library(ds-notification-shared SHARED ${CMAKE_SOURCE_DIR}/panels/notification/common/dbaccessor.cpp ${CMAKE_SOURCE_DIR}/panels/notification/common/notifysetting.h ${CMAKE_SOURCE_DIR}/panels/notification/common/notifysetting.cpp + ${CMAKE_SOURCE_DIR}/panels/notification/common/expiretimer.h + ${CMAKE_SOURCE_DIR}/panels/notification/common/expiretimer.cpp ) set_target_properties(ds-notification-shared PROPERTIES diff --git a/panels/notification/bubble/bubbleitem.cpp b/panels/notification/bubble/bubbleitem.cpp index 60d48a6d7..695a8d23b 100644 --- a/panels/notification/bubble/bubbleitem.cpp +++ b/panels/notification/bubble/bubbleitem.cpp @@ -51,6 +51,11 @@ qint64 BubbleItem::id() const return m_entity.id();
