- web/realtime_hub.py：RealtimeStreamHub——订阅集合变化按需启停 RealtimeDataFeed， 无人订阅完全停止轮询（对齐 QuoteStreamer 节能）；EventBus → 每连接队列 fan-out（丢最旧保最新）；去重标的上限 80；lifespan 挂载/关闭 - routers/realtime.py 重写：连接即订阅、断开退订、subscribe/unsubscribe 控制帧、 30s ping 心跳；单一写者泵模型（全部出站帧经队列串行，防并发 send 交错） - 修复 RealtimeDataFeed stop-before-start 竞态（_stop_requested 标志）， 补 2 个回归用例；hub 单测 10 例（并发订阅/退订竞态、跨标的串扰、背压、 TestClient 端到端） - 前端接入选文档方案（api_reference.md 协议+重连/心跳骨架；README 撤「未联动」）： SSE 已覆盖看板/自选实时刷新，WS 定位按需单标的 tick，双通道冗余无必要 - scripts/ws_smoke.py：手动冒烟（mock 模式实测 tick 帧与动态订阅确认可见）

"""ws_smoke — WebSocket 实时行情推送手动冒烟脚本（v1.28）。
|
||
|
||
连 ``/api/v1/ws/realtime/{symbol}``，打印收到的每一帧，验证
|
||
RealtimeDataFeed → EventBus → RealtimeStreamHub 的推送链路。
|
||
|
||
用法::
|
||
|
||
# 真实服务器（需 MAC 行情可达且在交易时段，或标的盘外有静止快照）
|
||
.venv/Scripts/python.exe scripts/ws_smoke.py --symbol SZ000001
|
||
|
||
# mock 模式（推荐本地冒烟：合成行情、不受交易时段限制）
|
||
# 终端 1：
|
||
EASY_TDX_E2E_MOCK=1 .venv/Scripts/python.exe -m easy_tdx serve --port 8000 --no-open-browser
|
||
# 终端 2：
|
||
.venv/Scripts/python.exe scripts/ws_smoke.py --url ws://127.0.0.1:8000/api/v1/ws/realtime/SZ000001
|
||
|
||
可选参数：--duration 秒数（默认 15）、--extra-symbol 运行中追加订阅的标的。
|
||
退出码：收到至少一帧 tick = 0，否则 1。
