"""飞书渠道插件生命周期钩子处理。
|
||
|
||
实现 ``LifecycleHookHandler`` Protocol,管理插件级资源(httpx 连接池),
|
||
响应宿主生命周期状态变迁。
|
||
|
||
设计要点:
|
||
- LifecycleHandler 为单实例(非 per-account),可持有 mutable 状态用于
|
||
资源管理(与适配器的 INV-5 无 mutable 状态约束不同)。
|
||
- httpx 连接池在 ``onInit`` 创建,``onUnload`` 关闭。
|
||
- WebSocket 长连接由 ``StreamWorker`` 通过 ``FeishuStreamConnectorAdapter``
|
||
统一管理,``LifecycleHandler`` 不再持有 WS 客户端句柄。
|
||
- ``onReconfigure`` 从配置 schema 派生不可热更新键列表
|
||
(``hot_reloadable=False``),变更时抛 ``ConfigRestartRequiredError``。
|
||
- ``onFail`` 不抛异常,不阻断降级流程;logger 不可用时回退 ``stderr``。
|
||
|
||
依赖方向:仅 import ``yuxi.channels.contract.*`` + 标准库 + httpx,
|
||
不污染框架层。
