Module: TelegramBotEngine::Registry

Defined in:
lib/telegram_bot_engine/registry.rb

Overview

Resolves and caches a Telegram::Bot::Client per Bot record, keyed by bot id (docs/0001 §2 cap 2, §3.2). This fills telegram-bot’s gap: ‘Telegram.bots` is boot-memoized (`@bots ||=`) and not built for runtime hot-add or token rotation. We resolve a fresh `Telegram::Bot::Client.new(token)` per bot_id rather than leaning on `Telegram.reset_bots`, which is unsafe under concurrency (docs/0001 §9).

def client_for(bot)
  @mutex.synchronize do
    @clients[bot.id] ||= build_client(bot)
  end
end

.invalidate(bot) ⇒ Object

Drop a bot’s cached client so the next resolve rebuilds it. Called from Bot#after_save / #after_destroy so token rotation can never serve a stale client.

def invalidate(bot)
  @mutex.synchronize { @clients.delete(bot.id) }
end

.reset! ⇒ Object

Clear the whole cache (test isolation; also safe to call on reload).
