#!/usr/bin/env python3 # -*- coding: utf-8 -*- """BSP 错误码与超时命名约定检查(机械检查那一半)。 为什么要有这个脚本:约定写在 docs 里不会自己生效。同一层的驱动今天并存六套返回约定, 而"能不能重试"只写在个别注释里;叫 *_TIMEOUT 的东西里既有真毫秒(单位靠不统一的 _MS 后缀表达)、 也有**返回码**。没有机械检查,新代码只会继续按各自旧习惯长。 四条检查(每项一个自描述标签 = 基线键的第二字段,格式是「文件|标签|名字」): err-type 公开 API 不得返回 HAL_StatusTypeDef / bool bool 把"为什么失败"整条丢掉;HAL 枚举把 HAL 焊进调用方的 include 链。 timeout-name *_TIMEOUT 宏不得取负值 名字叫 TIMEOUT 却是返回码,读代码的人会当成时长;超时应返回 BSP_ERR_TIMEOUT。 return-doc 非 void 的公开 API 必须在紧邻注释块里写「返回值:」 约定要能被读到,才算约定(也才谈得上审查)。匹配时忽略空格:规范 V1.0 允许列对齐写法 「返 回 值:」,门禁不去规定排版。 consume-result 返回错误码的函数,调用点必须**接住返回值**或**显式 (void) 丢弃** 名单自动取,不手写:① 返回 bsp_err_t 的公开 API(契约规定它就是错误码); ② 返回 int/int32_t 且文档块出现"错误码 / 失败 / BSP_ERR"的函数(覆盖 GD5F 私有码族); ③ 已知返回 HAL_StatusTypeDef 的 HAL 传输/读写族;④ 上面 ①② 同一套启发式再扫一遍 .c 里的 static 定义(只扫头文件等于只守跨编译单元的边界)。为什么单列:实测 ARMCC v5 不认 warn_unused_result、cppcheck 也不报这类丢弃(都在本仓实跑验证过)——**丢弃底层传输的 返回值,今天没有任何工具会响**。已知限度:只认单行整句的裸调用(行尾注释允许),跨行写的暂测不到。 术语迁移(2026-10-23):这四项原先叫 R1/R2/R3/R4,已整体改名。原因是 R1~R8 在本仓是"专项 风险"的裸形编号(scripts/id_registry.json 已登记那一族,保护规划与看门狗的风险表都在用)、 带连字符的那一族又是审查报告的可靠性 / 内存优化项编号——**同一个裸形四种意思**,而编号门禁 因为 docs/编号规范.md §4.3 的同号不同义白名单不会报, 等于机器放行、人看不懂。旧名到新名对照:R1=err-type、R2=timeout-name、R3=return-doc、 R4=consume-result;已提交的文档与变更记录里出现的老名按"冻结历史不回改"处理,以本对照为准。 增量拦截(与 layer-deps / id-check 同构):BASELINE 钉住存量,只减不增,没有 --write。 修完一条跑 --prune,它会点名"这条已消失,请从 BASELINE 删除"。 退出码:0 = 通过;1 = 有新增违规;2 = 用法或扫描错误。 """ import argparse import re import subprocess import sys from pathlib import Path ROOT = Path(__file__).resolve().parent.parent EXCLUDE = ("lftpd/",) # 存量基线(2026-10-23 清点):"文件|规则|名字"。修掉一条删一行,不要往里加。 BASELINE = frozenset( line.strip() for line in """ Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Receive#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Receive#2 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Receive#3 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#10 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#11 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#2 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#3 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#4 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#5 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#6 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#7 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#8 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|HAL_SPI_Transmit#9 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_bbt_save#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_block_erase#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_page_read#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_program_exec#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_program_load#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_read_from_cache#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_read_status#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_read_status#2 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_read_status#3 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_wait_busy#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_write_enable#1 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_write_enable#2 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_write_enable#3 Drivers/BSP/GD5F2GQ5UE/gd5f2gq5ue.c|consume-result|gd5f_write_enable#4 Drivers/BSP/GD5F2GQ5UE/nand_ftl.c|consume-result|gd5f_write_enable#1 Drivers/BSP/RS485/rs485.c|consume-result|rs485_receive_start#1 Drivers/BSP/RS485/rs485.c|consume-result|rs485_receive_start#2 Drivers/BSP/UI/ui_content_page.h|err-type|ui_content_page_open Drivers/BSP/UI/ui_net_sink.c|consume-result|net_close#1 Drivers/BSP/UI/ui_net_sink.c|consume-result|net_close#2 Drivers/BSP/UI/ui_net_sink.c|consume-result|net_close#3 Drivers/BSP/UI/ui_net_sink.c|consume-result|net_close#4 Drivers/BSP/UI/ui_net_sink.c|consume-result|net_close#5 Drivers/BSP/UI/ui_net_sink.c|consume-result|net_close#6 """.splitlines() if line.strip() ) DEFINE_RE = re.compile(r"^\s*#define\s+([A-Z][A-Z_0-9]*TIMEOUT[A-Z_0-9]*)\s+(-[0-9]+)", re.MULTILINE);
