| fix: replace DelayedSingleton with Meyer's singleton for StorageManagerConnect/CjStorageStatusService and clean up DelayedSingleton uses new(std::nothrow) which can return nullptr on OOM, causing crashes when callers dereference without checks. Meyer's singleton (static local reference) is C++11 thread-safe and never null. StorageManagerConnect: 44 arrow->dot replacements in kits_impl, 34 nullptr check blocks removed in taihe, SmDeathRecipient::OnRemoteDied fixed. CjStorageStatusService: 3 nullptr check blocks removed, CjSmDeathRecipient ::OnRemoteDied fixed. Move constructor and destructor to private for all three singleton classes to prevent external instantiation. Remove CreateForTesting/SetInstanceForTesting/GetInstanceForTesting/ ResetInstanceForTesting and instance_ptr_for_testing_ from StorageDaemonCommunication - testing utilities should not exist in business code. Update test files to use GetInstance() reference and ResetSdProxy(), following VolumeManagerService test pattern. Wrap over-120-char lines for cleancode compliance by extracting GetInstance() into local auto& reference.

| !2940 merge feat/metadata-split-to-free-and-system into master feat: HMFS metadata按比例拆分到freeSize和systemDataSize Created-by: dyylll Commit-by: dyylll;Dyylll Merged-by: openharmony_ci Description: **Description:** 将HMFS文件系统metadata按比例拆分到freeSize和systemDataSize，使存储空间显示更准确。 主要修改： - 将metadata计算从storage_daemon迁移到storage_manager，复用已有GetDataSizeByPath IPC - 新增StorageStatusManager::GetMetaDataSize，读取HMFS sysfs文件计算metadata大小 - 新增StorageTotalStatusService::GetDataTotalSize，获取/data分区总大小 - 修改GetFreeSize，按比例计算freeMetadata并累加，含降级保护 - 修改GetSystemDataSize，按比例计算usedMetadata并累加，含降级保护 - GetMetaDataSize包含乘法溢出和加法溢出检查 - 新增14个UT测试用例，覆盖所有分支（含正常路径和降级路径） **Issue number:** Fixes #2327 **Test & Result:** - 编译验证：hb build storage_service -i 成功，hb build storage_service -t 成功（677/677 targets） - 设备UT验证：RK3568开发板上执行，storage_status_manager_test 32/32 PASSED，storage_total_status_service_test 20/20 PASSED - 降级验证：Linux无HMFS环境下GetFreeSize正确降级返回statvfs原始值 **CodeCheck:** <table> <tr> <th>类型</th><th>自检项</th><th>自检结果</th> </tr> <tr> <td rowspan="2">多线程相关</td><td>在类的成员变量中定义了vector/map/list等容器类型，且在多个成员函数中有操作时，需要加锁保护</td><td>自检结果：不涉及，无共享可变状态</td> </tr> <tr> <td>定义全局变量，在多个函数中都有操作时，需要加锁保护</td><td>自检结果：不涉及</td> </tr> <tr> <td rowspan="4">内存相关</td><td>调用外部接口时，确认是否对返回值做了判断，尤其外部接口返回了nullptr的情况，避免进程崩溃</td><td>自检结果：已检查sdCommunication nullptr、IPC返回值</td> </tr> <tr> <td>调用安全函数时，如memcpy_s等，是否检查其返回值</td><td>自检结果：不涉及</td> </tr> <tr> <td>检查函数中是否涉及了内存或资源申请，注意每个异常退出流程是否已释放</td><td>自检结果：不涉及动态内存申请</td> </tr> <tr> <td>隐式内存分配场景：realpath、ReadParcelable序列化、cJSON相关函数时等</td><td>自检结果：不涉及</td> </tr> <tr> <td rowspan="4">校验外部输入</td><td>使用nlohmann:json解析外部输入时，需判断参数类型是否符合预期</td><td>自检结果：不涉及</td> </tr> <tr> <td>所有外部输入均不可信，需判断外部输入是否直接作为内存分配的大小等</td><td>自检结果：IPC返回值已做负值和溢出校验</td> </tr> <tr> <td>外部输入的路径不可信，需使用realpath做标准化处理</td><td>自检结果：路径为代码内硬编码常量，非外部输入</td> </tr> <tr> <td>外部输入包括IPC的proxy/stub接口等</td><td>自检结果：IPC返回值已做ret != E_OK校验</td> </tr> <tr> <td rowspan="2">数学运算</td><td>代码中是否混合了加减乘除等运算，需检查是否可能导致整数溢出或符号翻转</td><td>自检结果：已添加乘法溢出检查和加法溢出检查</td> </tr> <tr> <td>需检查代码是否有高精度数字转换为低精度的操作</td><td>自检结果：double转int64_t已做边界钳位</td> </tr> <tr> <td rowspan="1">秘钥相关</td><td>如变量临时保存了口令、秘钥等，需要在使用完成后及时清空</td><td>自检结果：不涉及</td> </tr> <tr> <td rowspan="2">权限相关</td><td>对外提供接口是否做了权限保护和校验</td><td>自检结果：不涉及新增接口</td> </tr> <tr> <td>内核对外提供了设备节点是否做了权限保护</td><td>自检结果：不涉及</td> </tr> <tr> <td rowspan="3">内核操作</td><td>是否有mmap操作及remap_pfn_range地址映射校验</td><td>自检结果：不涉及</td> </tr> <tr> <td>是否有copy_from_user并做长度校验</td><td>自检结果：不涉及</td> </tr> <tr> <td>是否有copy_to_user并做完整初始化</td><td>自检结果：不涉及</td> </tr> </table> See merge request: openharmony/filemanagement_storage_service!2940 | 8 天前 |
