fix: market-sync 2h timeout 截断 + 加 daily-check 巡检
work #01 (2026-07-03):昨天 15:30 runall 中 kline_5min 全量 69min 把 2h 窗口吃满,share_snapshot / market_regime 被 systemd SIGTERM 截断; 今天又叠加 worker.py 未长驻,导致 10 个 task missed。 变更: - bin/systemd/market-sync.service: TimeoutStartSec 7200 → 14400 (4h) - bin/daily_sync_check.py: 新增每日巡检,读 PG dataset_registry, 对比 SCHEDULE 判定 ok/missed/failed/stuck/never_run,写 JSON 报告, 失败时 POST HMAC webhook - bin/systemd/market-sync-daily-check.{service,timer}: 23:00 daily 触发 daily_check(替代 session-only 的 /loop 方案) - config/daily_check_secrets.env.template: webhook 配置模板 - docs/works/2026-07-03-01-market-sync-timeout.md: 完整 work 记录 (根因 + 中期/长期改进建议) Co-Authored-By: Claude <noreply@anthropic.com>

# 2026-07-03 — work #01: market-sync.service 2h timeout 截断同步
|
||||
|
||||
## 发现
|
||||
|
||||
跑 `bin/daily_sync_check.py --report-only`(周五 10:31)→ 10 个 missed:
|
||||
|
||||
```
|
||||
❌ stock_basic / kline_daily / kline_index / kline_5min / tick_trade
|
||||
❌ moneyflow / industry_sector / sector_features / market_regime / longhubang
|
||||
✅ share_snapshot (今日 00:03:01 手动跑过)
|
||||
⏸ stock_node (周末专属任务,今天周五不期望)
|
||||
```
|
||||
|
||||
## 根因
|
||||
|
||||
不是今天调度出问题,是**昨天 2026-07-02 15:30 runall 没跑完**:
|
||||
|
||||
```
|
||||
15:30:01 启动 runall
|
||||
15:38:50 stock_basic 完成 (529s)
|
||||
15:38:58 kline_index 完成 (2s)
|
||||
15:56:54 kline_daily 完成 (1072s) warning
|
||||
17:06:09 kline_5min 完成 (4150s=69min) ← 单 task 吃掉一半窗口
|
||||
17:22:37 industry_sector 完成 (983s) warning (baostock timeout)
|
||||
17:24:27 sector_features 完成 (105s)
|
||||
17:24:32 >>> 开始 share_snapshot
|
||||
17:30:01 systemd SIGTERM 杀进程 ← TimeoutStartSec=7200 (2h) 到期
|
||||
✗ share_snapshot 没跑
|
||||
✗ market_regime 没跑
|
||||
```
|
||||
|
||||
后果链:
|
||||
1. 昨天 kline_5min 全量同步 5207 只耗时 69 min(4150s),单 task 吃掉 1/2 窗口
|
||||
2. industry_sector 又因 baostock connection timed out 浪费 16 min
|
||||
3. 17:30 systemd timeout 砍掉 share_snapshot + market_regime
|
||||
4. 今天 09:00 该跑的 stock_basic 没跑 —— 因为 worker.py 没长驻 + market-sync.timer 只在 15:30 触发
|
||||
5. tick/moneyflow/lhb 几个独立 timer 在 21:05/21:35/22:00 跑过但今天又没补
|
||||
|
||||
## 解决
|
||||
|
||||
### 短期(本次 commit)
|
||||
|
||||
- `bin/systemd/market-sync.service`: `TimeoutStartSec` 从 `7200` (2h) 提到 `14400` (4h)
|
||||
- 注释 `实际 ~80min` → 改成 `~80min + kline_5min 增量 70min, 总 ~2.5h, 留 buffer`
|
||||
- 加 `bin/systemd/market-sync-daily-check.timer` + `.service`
|
||||
- 每天 23:00 跑 `bin/daily_sync_check.py`,替代 `/loop` 方案的 session-only 限制
|
||||
|
||||
### 中期(不在本次 commit,记录备查)
|
||||
|
||||
- kline_5min 改成增量模式(当前是全量 5207 只每次),预计从 69min 降到 5min
|
||||
- 增量条件:`bar_time >= 上次同步时间 - 1 天`(含补漏)
|
||||
- worker.py 长驻 + 进程内 scheduler 接管盘后 task 调度,与 systemd timer 二选一([[dual-scheduler-overlap]])
|
||||
- 失败 task 自动 retry 一次(仅 failed,不 retry partial-success / warning)
|
||||
|
||||
### 长期(架构改进)
|
||||
|
||||
- runall 拆成 fast-path / slow-path 两个 service:
|
||||
- fast-path: stock_basic / kline_index / kline_daily / industry_sector / share_snapshot / market_regime(~30min)
|
||||
- slow-path: kline_5min 全量(独立 timer @ 周日凌晨,避免挤占交易日窗口)
|
||||
|
||||
## 关联
|
||||
|
||||
- [[background-watcher-pitfalls]]: "不要让 systemd TimeoutStartSec= 自动收尾"
|
||||
- 实际情况是 runall 卡在 kline_5min,wrapper 的 fast-poll 也没起到作用(runall 在 2h 内确实没退出,systemd 超时是对的)
|
||||
- [[dual-scheduler-overlap]]: worker.py 没运行 → 完全依赖 systemd timer
|
||||
- [[market-data-overview]]: 任务耗时分布
|
||||
|
||||
## 验收
|
||||
|
||||
commit 后验证:
|
||||
```bash
|
||||
sudo cp bin/systemd/market-sync.service /etc/systemd/system/
|
||||
sudo cp bin/systemd/market-sync-daily-check.{service,timer} /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl restart market-sync.timer
|
||||
systemctl status market-sync-daily-check.timer
|
||||
# 等今晚 23:00 看 daily_check 报告
|
||||
```
