| | | | | | | | | | | (GH-21964) Currently, if `asyncio.wait_for()` itself is cancelled it will always raise `CancelledError` regardless if the underlying task is still running.

* Fix asyncio.to_thread() documented return type (GH-20547)Miss Islington (bot)2020-05-311-1/+1
| | | | | | | | When I wrote the documentation for `asyncio.to_thread()`, I mistakenly assumed that `return await loop.run_in_executor(...)` within an async def function would return a Future. In reality, it returns a coroutine. This likely won't affect typical usage of `asyncio.to_thread()`, but it's important for the documentation to be correct here. In general, we also tend to avoid returning futures from high-level APIs in asyncio.

| | | | | | | | | | | | | | | (GH-20054) Currently, if asyncio.wait_for() timeout expires, it cancels inner future and then always raises TimeoutError. In case those future is task, it can handle cancelation mannually, and those process can lead to some other exception. Current implementation silently loses thoses exception. To resolve this, wait_for will check was the cancelation successfull or not. In case there was exception, wait_for will reraise it. Co-authored-by: Roman Skurikhin <roman.skurikhin@cruxlab.com>
