"""verify_log.py - 对抓取的 MCU 调试日志做标记校验（纯标准库，2026-09-20 替代 verify_log.ps1）。
|
||
|
||
用于 @test 闭环：烧录后从串口助手日志提取的开机日志交给本脚本 grep 标记，
|
||
输出结构化判定（格式与旧 PowerShell 版逐字一致，下游文档/习惯不受影响）。
|
||
|
||
用法:
|
||
& '.venv\\Scripts\\python.exe' test/host/verify_log.py --log-path <file>
|
||
[--required 'marker1;marker2']
|
||
[--forbidden 'FAIL;ERROR;HardFault;assert;[ERR]']
|
||
[--require-suite-summary 'Storage Tests;GD5F2GQ5UE Tests']
|
||
[--require-selftest-pass] [--selftest-log <selftest.log 本地副本>]
|
||
[--show-tail-lines 40]
|
||
[--max-boot-count 1] [--boot-marker 'reset cause:']
|
||
[--expect-reset-cause 'software;power-on']
|
||
[--require-order 'App init OK>Network Init>net init: OK']
|
||
[--done-marker 'net init: OK'] [--max-boot-ms 8000] [--json]
|
||
|
||
退出码（与旧版一致）:
|
||
0 = PASS（所有 Required 标记找到，Forbidden 零命中，汇总行要求满足）
|
||
1 = FAIL（缺 Required / 命中 Forbidden / 汇总行要求不满足）
|
||
2 = ERROR（日志文件不存在/不可读）
|
||
|
||
默认 Required 标记对应 STM32F4-Base 启动序列（见 App/app/app_main.c + App/task/net_task.c），
|
||
按测试用例覆盖，例如:
|
||
--required 'App init OK;net init: OK;PHY: 100M FULL'
|
||
--forbidden 'FAIL;ERROR;HardFault;assert;[ERR]'
|
||
|
||
语义约定（与旧 PowerShell 版对齐）:
|
||
- Required：大小写敏感子串匹配（全文）
|
||
- Forbidden：大小写**不敏感**子串匹配、逐行计数（旧版 -like 语义；
|
||
如 Forbidden 'FAIL' 会命中 "write /log/run.log fail (7)" 这类行）
|
||
- 固件错误级日志前缀是 `[ERR]`（`DBG_ERROR`，形如 `[时间][ERR][TAG] 消息`），
|
||
与 `ERROR` 子串**不匹配**——默认 Forbidden 因此显式包含 `[ERR]`，驱动/模块
|
||
错误行不再漏检（2026-09-21 修复）。测试套件中**预期**出现 `[ERR]` 的用例
|
||
（如 GD5F DMA 守卫负路径、FatFs 非法名校验）须用 --forbidden 覆盖默认值。
|
||
- 读取编码：先按 UTF-8，解码失败回退系统 locale 编码（旧版 Get-Content 行为）
|
||
- 控制台输出重配置为 UTF-8（errors=replace）：任何 Windows 控制台代码页
|
||
都只影响终端显示，不会导致本脚本崩溃
|
||
- 汇总行（2026-10-01 加，T-2）：纯 Required 子串匹配有个盲区——套件启动横幅
|
||
命中即判 PASS，**套件是否跑到汇总行、断言数是否为 0 完全不可见**（套件中途
|
||
挂死/复位、或 Phase 宏全关时会被误判为通过）。`--require-suite-summary`
|
||
要求日志中出现 `=== <名称>: N/M PASSED (failed=0) ===` 且 **N > 0**。
|
||
- 自检记录联合判定（S7，2026-10 实机窗口）：`--require-selftest-pass` 对 /log/selftest.log
|
||
的本地副本（定长 64B 记录，格式见 App/log/sys_log.h）判定。自检仅故障写盘（v1 不记
|
||
通过项）：**文件缺失 / 0 字节 = 无故障 → PASS**；存在任何一条记录 = 有故障 → FAIL
|
||
（退出码 1），并逐条打印时间戳 + 描述。抓取失败（设备不可达 / FTP 错误等）由调用方
|
||
（run_boot_test.py）先打 WARN，本地文件按缺失处理 → 按上述规则不判整体 FAIL。
|
||
- 启动锚点计数（2026-10-10）：`--max-boot-count N`（run_boot_test.py 默认传 1）统计
|
||
`reset cause:` 锚点出现次数——**0 次** = 采集没从复位开始（标记全中也可能只是上一轮
|
||
的残留日志）；**>N 次** = 板子在采集窗口内自己复位过（IWDG 咬狗 / Fault 后
|
||
`NVIC_SystemReset` / 掉电重启），此前这类运行只要不命中 Forbidden 就判 PASS。
|
||
`--expect-reset-cause` 对第一个锚点做原因白名单（大小写不敏感子串），空 = 只报告不判。
|
||
- Forbidden 命中行（2026-10-10）：命中时逐行打印**行号 + 内容**（最多 6 行，超出报剩余数）。
|
||
旧实现只说 `forbidden pattern: [ERR] (3 line(s))`，人还得自己再 grep 一遍才知道是哪几行
|
||
——而"是哪几行"恰恰是定位要的东西。
|
||
- 标记顺序（`--require-order 'a>b>c'`）：按**首次出现的行序**校验启动步骤先后。标记全中
|
||
但顺序颠倒 = 某步在另一步之后补做（屏障失序、重试后补跑），旧实现完全看不见。
|
||
- 开机耗时（`--done-marker` + `--max-boot-ms`）：依赖行首 `[+Nms]` 前缀（run_boot_test.py
|
||
2026-10-10 起按 daemon 毫秒时基给每行加，MCU 侧时间戳只有秒级且开机头几行根本没有）。
|
||
量"第一行 → done-marker"的真实耗时，抓"能开机但慢了几秒"（mount 重试 / PHY 重协商）。
|
||
日志里没有该前缀 → 只 WARN 跳过，不假判 FAIL。
|
||
- `--json`：同一套判定以 JSON 输出（供 CI / 上层脚本消费；退出码语义不变）。
