From aaba339616df921b3fc90a688e0edd79cc4fe329 Mon Sep 17 00:00:00 2001 From: zhanghongyuan Date: Fri, 23 Oct 2026 16:32:38 +0800 Subject: [PATCH 1/2] fix: resolve 7 defects in devicemanager source code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. D1: networkIsOnline Qt6 branch used == instead of != for Disconnected check, returning true when offline (inverted) 2. D2: slotInstallProgressFinished called removeAt(indexOf()) without checking -1, causing out-of-bounds removal 3. D3: setCheckedCBDisable dereferenced mp_HeaderCb without null check, crashing when header checkbox not initialized 4. D4: setTimeout(1000*1000) set 1000s timeout on DBus calls, blocking when service unavailable; restored to default (-1) 5. D5: destructor used deleteLater on child layout after DELETE_PTR on parent, causing use-after-free 6. D6: slotClose emitted refreshInfo and called close, triggering closeEvent which re-entered slotClose causing duplicate refresh 7. D7: isRunning matched objectName "PageDriverControlWindow" which no code sets, making running check always false Log: Fixed multiple crash, hang, and logic defects in device manager Influence: 1. Test network status detection under online and offline conditions 2. Test driver installation progress and index list management 3. Test checkbox operations when header is not initialized 4. Test DBus calls when driver service is unavailable 5. Test window close during driver processing states fix: 修复设备管理器7项源码缺陷 1. D1：networkIsOnline Qt6分支使用==而非!=判断Disconnected， 导致断网时返回true（逻辑反置） 2. D2：slotInstallProgressFinished中removeAt(indexOf())未检查-1， 索引不存在时越界删除 3. D3：setCheckedCBDisable未判空直接解引用mp_HeaderCb， 表头复选框未初始化时崩溃 4. D4：setTimeout(1000*1000)设置1000秒超时，服务缺失时阻塞； 恢复为默认超时(-1) 5. D5：析构函数先DELETE_PTR父布局再deleteLater子布局， 导致use-after-free 6. D6：slotClose同时emit refreshInfo和close，触发closeEvent 重入slotClose导致重复刷新 7. D7：isRunning匹配objectName "PageDriverControlWindow"全工程 无人设置，运行状态检查永远返回false Log: 修复设备管理器多处崩溃、卡死和逻辑缺陷 Influence: 1. 测试联网和断网状态下的网络状态检测 2. 测试驱动安装进度和索引列表管理 3. 测试表头未初始化时的复选框操作 4. 测试驱动服务不可用时的DBus调用 5. 测试驱动处理各状态下的窗口关闭操作 PMS: BUG-7 --- .../src/DriverControl/DBusDriverInterface.cpp | 6 +++--- deepin-devicemanager/src/Page/PageDriverControl.cpp | 5 ++--- deepin-devicemanager/src/Page/PageDriverManager.cpp | 7 +++++-- deepin-devicemanager/src/Widget/DetectedStatusWidget.cpp | 1 + deepin-devicemanager/src/Widget/drivertableview.cpp | 2 +- 5 files changed, 12 insertions(+), 9 deletions(-) diff --git a/deepin-devicemanager/src/DriverControl/DBusDriverInterface.cpp b/deepin-devicemanager/src/DriverControl/DBusDriverInterface.cpp index d3491d3bf..6896bf55d 100644 --- a/deepin-devicemanager/src/DriverControl/DBusDriverInterface.cpp +++ b/deepin-devicemanager/src/DriverControl/DBusDriverInterface.cpp @@ -34,7 +34,7 @@ void DBusDriverInterface::uninstallPrinter(const QString &vendor, const QString qCDebug(appLog) << "Uninstall printer - vendor:" << vendor << "model:" << model;
