主机单测：新增卷锁与时间同步两套用例（33+80 项）并登记钩子
- vol_lock（App/fs/vol_lock.c）：33 用例。核心不变量是 fail-open—— 互斥量创建失败时 vol_lock_wait() 必须返回 1 且绝不阻塞，因为调用者 defaultTask 是看门狗喂狗点；板端该路径只在内存耗尽时才可能走到。 - time_sync（App/sync/time_sync.c）：80 用例。本模块是 N-17 看门狗风险的 全部逻辑贡献者，用例钉死分片喂狗节奏、监听退避、报文重组（半包/粘连/ EOF/真错/预算耗尽/tick 回绕）、重听门控；用 longjmp 跳出 for(;;) 任务循环。 - 两套均为纯逻辑主机侧测试，MSVC 离线编译真实源文件（#include 纳入）。 - 新增钩子 vol-lock-unit-test、time-sync-unit-test（7f/7g）。 - 全量主机单测：watchdog 39 + sys_clock 100 + cfg_file 149 + phasor 57 + adc_input 70 + vol_lock 33 + time_sync 80 = 528 项，全绿。

/*
|
||||
* 模块名称：Time Sync（PC 本地时间推送接收）主机侧单元测试
|
||||
* 模块功能：在 PC 上对 App/sync/time_sync.c 做离线验证（4 个函数全覆盖：
|
||||
* time_sync_delay_fed / time_sync_open_listener / time_sync_handle_conn /
|
||||
* time_sync_task）。
|
||||
*
|
||||
* 被测对象：真实源文件 ../../../App/sync/time_sync.c（以 #include 原样纳入，
|
||||
* 保证测的是生产代码而非副本）。平台依赖由本文件提供的**可注入桩**实现：
|
||||
* - FreeRTOS/task.h -> vTaskDelay / xTaskGetTickCount（可控时钟）
|
||||
* - net_socket.h -> socket/bind/listen/accept/close/recv_to/
|
||||
* get_generation/htons（全部脚本化）
|
||||
* - sys_events.h -> osEventFlagsWait（可注入"未就绪"）
|
||||
* - sys_clock.h -> sys_clock_set_unix（记录 epoch）
|
||||
* - task_watchdog.h -> task_wd_beat / task_wd_bind（记录心跳节奏）
|
||||
* - dbg_log.h -> DBG_ERROR/DBG_INFO 计数
|
||||
*
|
||||
* 为什么要主机侧单测（而不是只用板端套件）：
|
||||
* 1. **本模块是 N-17 的当事方**：登记簿 N-17 记录"time_sync 监听重建期间心跳缺口
|
||||
* 800ms~1s，距 IWDG 最坏超时 1701ms 余量仅 ~0.7s"。缺口的成因全部是本模块的
|
||||
* **纯逻辑**——分片延时（delay_fed）的心跳节奏、监听重试退避（500/2000ms）、
|
||||
* accept 轮询退避（200ms）、收尾延时（50ms）、以及"屏障等待态也要喂心跳"。
|
||||
* 这些在真机上只能靠"跑起来看复位不复位"间接观察，主机侧可**逐片断言**。
|
||||
* 2. **时间包重组状态机**（handle_conn）是纯逻辑：累积到 8 字节才解析、30s 总预算
|
||||
* 随 tick 推进耗尽、TCP 分段送达、EOF/真错误/超时三种返回码分支——板端套件
|
||||
* 无法精确构造"分段 + 预算耗尽 + tick 回绕"的组合。
|
||||
* 3. 不占 MCU 的 RAM，毫秒级完成。
|
||||
*
|
||||
* 覆盖点（TC-TS-xxx）：
|
||||
* —— time_sync_delay_fed（可喂心跳的分片延时）——
|
||||
* TC-TS-001 0ms 不睡眠不喂狗
|
||||
* TC-TS-002 恰好一片（50ms）
|
||||
* TC-TS-003 非整片（120ms）切成 50/50/20，每片喂心跳
|
||||
* TC-TS-004 长延时（2000ms）= 40 片 × 50ms，每片喂心跳
|
||||
* TC-TS-005 不足一片（49ms）单片处理
|
||||
* TC-TS-006 总预算 30s = 600 片（片长上限恒 50ms）
|
||||
* —— time_sync_open_listener（监听建立与重试）——
|
||||
* TC-TS-010 首次成功：socket/bind/listen 各一次，端口经 net_htons，无退避
|
||||
* TC-TS-011 bind 失败 -> 关 socket + 退避 2000ms + 留痕，随后重试成功
|
||||
* TC-TS-012 listen 失败 -> 关 socket + 退避 2000ms，随后重试成功
|
||||
* TC-TS-013 socket 连续失败 -> 5 次后返回 -1（5 条 ERROR，5×500ms 退避）
|
||||
* TC-TS-014 第 3 次重试成功并返回新描述符
|
||||
* TC-TS-015 每次重试前 + 每片延时各喂一次心跳，且心跳位恒为 TIMESYNC
|
||||
* —— time_sync_handle_conn（时间包重组状态机）——
|
||||
* TC-TS-020 8 字节一次收齐 -> 大端解析 epoch + 更新墙钟 + 关连接
|
||||
* TC-TS-021 分段送达（4+4）-> 累积后解析；第二次只请求剩余 12 字节
|
||||
* TC-TS-022 一次到达 16 字节 -> 只取前 8 字节
|
||||
* TC-TS-023 前缀非 "TIME" -> 不更新墙钟，但仍关连接
|
||||
* TC-TS-024 对端关闭（n==0）-> 立即退出、不解析
|
||||
* TC-TS-025 真错误（n==-1）-> 立即退出、不解析
|
||||
* TC-TS-026 只收到 4 字节后 EOF -> 不足 8 字节不解析
|
||||
* TC-TS-027 30s 预算耗尽 -> 留痕 "no TIME packet in 30s, drop conn"
|
||||
* TC-TS-028 剩余预算不足一片 -> 末片按剩余（20ms）切分
|
||||
* TC-TS-029 32 位 tick 回绕 -> 预算计算仍正确
|
||||
* —— time_sync_task（任务主循环）——
|
||||
* TC-TS-040 sys_evtHandle==NULL：跳过就绪屏障；accept 轮询->成功->处理->收尾
|
||||
* TC-TS-041 就绪屏障：100ms 分片等待 NET_READY（osFlagsNoClear 不消费就绪位）
|
||||
* TC-TS-042 屏障未就绪期间持续喂心跳（2026-10-02 台架根因的回归防线）
|
||||
* TC-TS-043 网络代次变化 -> 关闭旧监听并重监听
|
||||
* TC-TS-044 监听建立失败 -> 5 次重试后放弃并退避 2000ms
|
||||
*
|
||||
* 通过：全部 TC PASS（main 返回 0）。
|
||||
* 入口：int main(void)，返回 0=PASS / 1=FAIL（由 run 脚本判读）。
|
||||
*
|
||||
* 创建日期：2026-10-10
