- Flask + SQLAlchemy 物料/入库/出库/BOM/生产订单全模块管理 - PyInstaller 打包为单文件 EXE (双击运行, 自动建库) - 物料维度: 入库总数量 / 消耗总数量 / 逐次入库流水(含时间) - BOM 详情展示组成物料的规格型号与单套用量 - 支持 Altium / 嘉立创 BOM 批量导入(文本与 Excel 双通道) - 内置端到端验证脚本(tools/_exe_util.py 等, 清理进程树防残留)

"""EXE 启动 / 清理公共工具。
|
|
|
|
背景(踩坑记录):
|
|
PyInstaller `--onefile --windowed` 的启动器(runw.exe)会**派生子进程**运行真正的
|
|
Flask 服务器。若只 `p.terminate()` 父进程,子进程会残留并继续霸占 8080；
|
|
Windows 允许同一端口被多个 socket 绑定,于是后续请求会被**随机路由到旧实例**,
|
|
表现为: 随机 500、改了模板/代码"不生效"、时好时坏的返回内容。
|
|
|
|
正确做法:
|
|
1) 启动前按可执行文件路径清掉 dist 下所有 EXE(兼容 *.old.exe / _prev_*.exe 等改名备份);
|
|
2) 收尾用 `taskkill /F /T /PID` 杀掉**整棵进程树**,再兜底按路径清一次。
