# 临时文件命名与多实例安全
|
||||
|
||||
> 记录全库临时文件(ACIS SAT、DWG 中转等)的命名规则、现状与遗留项。
|
||||
> 最后更新:2026-10-22
|
||||
|
||||
## 规则
|
||||
|
||||
1. 文件名必须带 `GetCurrentProcessId()`,直接用 `CoreTools::getTempFilePath()` 生成。同一进程内需要多次独立使用、彼此不能共享的,再加原子递增序号。
|
||||
2. 用完即删(`::DeleteFile`)。写读双方跨函数隐式传递的文件除外,见下文 `JMSJ.sat`。
|
||||
3. 路径统一用 `FilePath::getSystemTemporaryFolder()`,不要落到安装目录。
|
||||
4. 从 DWG 里读回来的文件名不可信,必须只取纯文件名,拒绝 `..\`、盘符等路径成分。
|
||||
5. 从文件读进缓冲区再当字符串用时:分配 `nLen + 1`、清零,按 `Read` 实际返回的长度构造 `CString`,不要直接 `CString = pszTxt`。
|
||||
|
||||
## 现状
|
||||
|
||||
| 位置 | 改前 | 改后 | 状态 |
|
||||
| --- | --- | --- | --- |
|
||||
| `CoreCommand/CoreTools.cpp` `MakeTempSatPath` | — | `x3d_<pid>_<seq>.sat` | 已符合,调用方负责删除 |
|
||||
| `CoreLibrary/AcDbX3dSolid.cpp` `CreateFromSat` | `temp\temp.sat` | `temp_<pid>_<seq>.sat` | 已修,用完删除 |
|
||||
| `CoreLibrary/AecDbEwPipeBase.cpp` `RegionAcisoutDwgOutFields` | `Region_<handle>.dat` | `Region_<pid>_<tag>.dat` | 已修;未入库实体无句柄时用序号 `N<n>` |
|
||||
| `Pool3dCmd/JMDBDlg.cpp` `JMSJDlg.cpp` `HZQTDlg.cpp` | `JMSJ.sat` | `JMSJ_<pid>.sat` | 已修,见下文 |
|
||||
| `CoreCommand/KTEarthWormCmd.cpp` `CO_RGCSCmdFnc` | `Region_<handle>.dat` | 未改 | 测试命令,不在产品链路,暂不处理 |
|
||||
| `DGJM.sat` 20 处 | `DGJM.sat` | 未改 | 代码已废弃,见下文 |
|
||||
| `PipelineCmd` `temp_$_$_.equ`、`tmp_dwg_$$%d.dwg` | 固定名 | 未改 | 界面导出路径,多实例会冲突,低优先级 |
|
||||
|
||||
## DGJM.sat:废弃代码,不再处理
|
||||
|
||||
分布:`AcDbX3dSolid.cpp`(2)、`AecDbEarthWormFitting.cpp`(2)、`AcDbX3dGroup.cpp`(3)、`EarthWormCmd/*`(13)。
|
||||
|
||||
这是写方 `acisOut` 和读方 `acisIn` 之间的隐式约定:A 函数把 region 写到固定文件,B 函数再从同一个文件读回来。加 PID 或序号会让读方找不到文件,必须先把接口改成「写方返回路径、读方接收路径」才能动。
|
||||
|
||||
该链路已整体废弃,**文件名保持原样,不再改造**。只在 PR #31 中修了读取越界:`new char[n]` 后直接赋给 `CString` 会把堆里的随机字节当字符串读,现改为 `new char[n+1]` + 清零 + 按实际长度构造。涉及 `AcDbX3dSolid`、`AecDbEarthWormFitting`、`DGJMDlg`、`GJYXJMDlg`、`JMDBDlg`、`JMSJDlg` 共 6 处。
|
||||
|
||||
若将来这段代码被复用,先改接口,再按本文规则命名。
|
||||
|
||||
## JMSJ.sat:水池截面中转
|
||||
|
||||
7 处,分布在 3 个文件:
|
||||
|
||||
| 文件 | 用途 |
|
||||
| --- | --- |
|
||||
| `JMDBDlg.cpp` | 从标准库选截面(写)→ `acisIn`;`acisOut` 导出截面字符串(读) |
|
||||
| `JMSJDlg.cpp` | `ShowLastSection` 读上次截面;入库时 `acisOut` 导出;从标准库选截面(写)→ `acisIn` |
|
||||
| `HZQTDlg.cpp` | 从标准库选截面(写)→ `acisIn`,两处 |
|
||||
|
||||
目录原本分两套:`JMDBDlg` / `JMSJDlg` 用 `FilePath::getSystemTemporaryFolder()`,`HZQTDlg` 用 `FilePath::GetSysDir()`(安装目录下的 `sys`)。两套互不相干,本次只加 PID 后缀,目录未动。
|
||||
|
||||
统一走 `CoreTools::getTempFilePath()`(`CoreCommand/CoreTools.cpp`):
|
||||
|
||||
```cpp
|
||||
CString sFullPath = CoreTools::getTempFilePath(_T("JMSJ_"), _T(".sat")
|
||||
, FilePath::getSystemTemporaryFolder());
|
||||
// -> <temp>\JMSJ_<pid>.sat
|
||||
```
|
||||
|
||||
`getTempFilePath` 是通用工具:主名 + 可选进程号 + 可选实体 id + 后缀;父目录为空或不存在时落到系统临时目录。
|
||||
|
||||
同一进程内所有调用点返回同一路径,所以 `acisOut` 写完、`ShowLastSection` 再读这条隐式链路仍然成立;进程之间用 PID 隔离,两个 CAD 实例不会再互相覆盖。
|
||||
|
||||
**已知取舍**:`CJMSJDlg::ShowLastSection` 在 `OnInitDialog` 里读这个文件,只用于对话框打开时显示上一个设计好的截面,不是功能数据。加 PID 后新进程读不到上个进程留下的截面,已确认可接受。
|
||||
|
||||
## 待处理
|
||||
|
||||
- `PipelineCmd` 的 `temp_$_$_.equ`、`tmp_dwg_$$%d.dwg`:界面导出路径,多实例会冲突,暂未改。
