In conclusion, attaching an asyncio event loop to a different loop allows us to integrate asyncio with other libraries or frameworks that provide their own event loops. By using theset_event_loopandget_event_loopfunctions provided by the asyncio library, we can run asyncio tasks concurrently with...

When I execute the test I get an exception with the message "attached to a different loop". Digging into that matter I found that pytest-asyncio creates a new event_loop for each test case (right?). The Elasticsearch client however, takes the default loop on instantiation and sticks with ...
RuntimeError: ... attached to a different loop 为什么只移动了锁定义,就会发生这种情况呢?这是 asyncio 库的一个令人困惑的地方,而且这种现象也不是锁特有的,asyncio 中的大多数对象都提供一个可选的 loop 参数,允许你指定要运行的特定事件循环。当未提供此参数时,asyncio 尝试获取当前正在运行的事件循环,如果...
asyncio.BaseEventLoop就是事件循环基类了,子类常用的是_UnixSelectorEventLoop,但核心调度逻辑都在基类中,其中最主要的是run_forever函数用来启动事件循环;另一个主要的函数是create_task,用来创建一个Task对象并放到事件循环中,准备在下一次循环时执行。

2、got Future attached to a different loop 这个报错的逻辑是什么? 我们要限制一个协程的并发数的时候,可以在调用协程之前,先初始化一个Semaphore对象。然后把这个对象传到需要限制并发的协程里面,在协程里面,使用异步上下文管理器包住你的正式代码。 报错的逻辑就是你初始化了但没有传到协程里面。导致不在同一个...
