 # Config Manager
-## Description
-This package was created to run my applications.
-The ConfigManager class implements the entry point for the program and provides the actual application configuration. It also simplifies logging setup.
+## Описание
+Пакет предназначен для запуска приложений с периодическим выполнением логики, перезагрузкой конфига и управлением по HTTP API.
 
-## Installation
+**Контракт:** приложение наследует **ConfigManagerV2**, переопределяет **execute()** (периодическая работа). Управление (старт/стоп, health) — через каналы, которые создаются снаружи и передаются в конструктор в **control_channels** (в т.ч. HttpControlChannel для API).
+
+## ConfigManager: устройство и взаимосвязи
+
+**ConfigManager** (класс ConfigManagerV2) — точка входа приложения. Он наследует внутреннюю логику от **\_RuntimeController** (циклы воркера и обновления конфига, запуск/остановка каналов управления).
+
+**Ядро (core):**
+- **ConfigLoader** — читает конфиг из файла (YAML/JSON), считает хеш и отдаёт конфиг только при изменении; при ошибке парсинга возвращает последний валидный конфиг.
+- **WorkerLoop** — в отдельном потоке циклически вызывает ваш метод `execute()` с паузой между вызовами; реагирует на событие остановки и колбэки успеха/ошибки.
+- **LogManager** — применяет секцию `log` из конфига к логированию (dictConfig).
+- **HealthAggregator** — собирает состояние: жизненный цикл (idle/starting/running/…), время последнего успешного `execute()` и таймаут здоровья; формирует единый ответ для health (ok/unhealthy).
+- **ControlChannelBridge** — один мост для всех каналов: обработчики on_start/on_stop/on_status (сброс/установка halt, текст статуса).
+
+**Каналы управления (control):**
+- **ControlChannel** — абстрактный контракт: `start(on_start, on_stop, on_status)`, `stop()`.
+- **HttpControlChannel** — HTTP API (`/health`, `/actions/start`, `/actions/stop`, `/actions/status`); использует **UvicornServerRunner**; для `/health` вызывает **HealthAggregator.collect()**, для действий — переданные обработчики из **ControlChannelBridge**.
+- **TelegramControlChannel** — реализация через long polling Telegram; команды `/start`, `/stop`, `/status` вызывают переданные обработчики.
+
+**Поток работы:** при `start()` менеджер поднимает каналы из **control_channels** (заданные снаружи), затем запускает два цикла: **WorkerLoop** и периодическое обновление конфига через **ConfigLoader**. Управление по API: `/health`, `/actions/start`, `/actions/stop` — если в control_channels передан **HttpControlChannel**. Остановка по halt завершает оба цикла; в конце останавливаются все каналы.
+
+## Запуск приложения с ConfigManagerV2 и HttpControlChannel
+
+1. **Наследуйте ConfigManagerV2** и реализуйте метод `execute()` (в нём — ваша периодическая работа). При необходимости переопределите `get_health_status()` для кастомного ответа `/health`.
+
+2. **Создайте каналы снаружи и передайте в конструктор.** Для HTTP API создайте **HttpControlChannel**; для health нужен колбэк менеджера — передайте **control_channels** как фабрику (lambda, получающую менеджер):
+   ```python
+   from config_manager.v2.control import HttpControlChannel
+
+   app = MyApp(
+       str(path_to_config),
+       control_channels=lambda m: [
+           HttpControlChannel(
+               host="0.0.0.0",
+               port=8000,
+               timeout=3,
+               health_provider=m.get_health_provider(),
+           )
+       ],
+   )
+   ```
+   Либо передайте готовый список каналов: `control_channels=[channel1, channel2]`.
+
+3. **Запустите из async-контекста:** `await app.start()` или `asyncio.create_task(app.start())` для фона. Остановка: `await app.stop()` или запрос `/actions/stop` по HTTP.
+
+**Минимальный пример с HTTP API:**
+
+```python
+import asyncio
+import logging
+from pathlib import Path
+
+from config_manager import ConfigManager
+from config_manager.v2.control import HttpControlChannel
+
+class MyApp(ConfigManager):
+    def execute(self) -> None:
+        pass  # ваша периодическая работа
+
+async def main() -> None:
+    app = MyApp(
+        str(Path(__file__).parent / "config.yaml"),
+        control_channels=lambda m: [
+            HttpControlChannel(
+                host="0.0.0.0", port=8000, timeout=3,
+                health_provider=m.get_health_provider(),
+            )
+        ],
+    )
+    asyncio.create_task(app.start())
+    await asyncio.sleep(3600)
+
+if __name__ == "__main__":
+    logging.basicConfig(level=logging.INFO)
+    asyncio.run(main())
+```
+
+Готовый пример: `tests/test_app.py`.

+
+## Логирование
+Логирование настраивается из конфигурационного файла только если в нём есть секция **`log`** в формате [dictConfig](https://docs.python.org/3/library/logging.config.html#logging.config.dictConfig). Если секции `log` нет, менеджер пишет предупреждение в лог, а уровень Python по умолчанию (WARNING) сохраняется — сообщения INFO/DEBUG могут не отображаться.
+
+**Как проверить, что конфигурация логирования применилась:**
+- Убедитесь, что путь к файлу конфига верный и файл загружается при старте (в логах нет ошибки чтения конфига).
+- Убедитесь, что в конфиге есть ключ `log` с `version: 1`, `handlers` и `loggers` (пример — `tests/config.yaml`).
+- После старта в логе должно появиться сообщение уровня INFO: `"Logging configuration applied"` (из `config_manager.v2.core.log_manager`). Если его нет, либо секция `log` отсутствует (будет предупреждение), либо уровень root/пакета выше INFO.
