use sys.get_asyncgen_hooks().finalizer to sniff io

Fixes #20 #27

graingert

this works for trio curio and asyncio already. All twisted needs to do is implement set_asyncgen_hooks ```python def sniffio(_get_asyncgen_hooks=sys._get_asyncgen_hooks): hooks = _get_asyncgen_hooks() finalizer = hooks.finalizer if finalizer is not None:...

mis-detects curio as asyncio when running in curio in asyncio.to_thread (py3.9)

```python import curio import sniffio import asyncio async def current_framework(): return sniffio.current_async_library() async def amain(): sniffio.current_async_library() return await asyncio.to_thread(curio.run, current_framework) print(asyncio.run(amain())) # prints asyncio - should print curio ```

The same principle that exists in the asynchronous world, exists in the synchronous world as well. I've been bitten enough by gevent's monkey patching, that I think that if library...

While tracking down a `ResourceWarning` about an unclosed event loop, I discovered that `asyncio.Task.get_current()`, used by sniffio, calls `asyncio.get_event_loop()` which creates a new event loop. To avoid this, we should...

SniffIO doesn't detect asyncio when running sync callbacks in loop

4

As discussed in https://github.com/agronholm/anyio/discussions/501 SniffIO doesn't detect it's running in asyncio when executing a callback added with `loop.call_soon_threadsafe` since it relies on `asyncio.get_current_task` for detection. Using `asyncio.get_running_loop` should from my...

Clarify what counts as 'running'

1

As proposed in #38, this PR updates sniffio's documentation and `asyncio` detection to adopt a consistent stance on what counts as "currently running". Now, user code that is invoked by...
