Root Cause

Calling lock.release() on an asyncio.Lock that is not currently held.

generic

中文

在未持有的asyncio.Lock上调用lock.release()。

Workarounds

  1. 100% success 
    async with lock: ...
  2. 95% success 
    await lock.acquire(); try: ... finally: lock.release()

Dead Ends

Common approaches that don't work:

  1. 90% fail

    acquire() is a coroutine; must be awaited.

  2. 70% fail

    It's a race condition; the lock may be released between check and release.
