Summary of discussion at

* `asyncio.Stream.write()` will start throwing a `DeprecationWarning` asking people to add an `await` if they didn't;

* `asyncio.Stream.close()` will start throwing a `DeprecationWarning` asking people to add an `await` if they didn't;

* `asyncio.Stream.drain()` & `asyncio.Stream.wait_closed()` will start throwing a `DeprecationWarning` telling about a scheduled removal (in Python 3.12) when used on `Process.std*` streams;

* `asyncio.Stream.drain()` & `asyncio.Stream.wait_closed()` will not work at all on Streams created via new 3.8 APIs: `connect()` & `StreamServer`.

This should no longer be a release blocker for 3.8 with the reversion of the new asyncio streaming API in GH-16455.
msg353542 - (view) Author: Kyle Stanley (aeros) * (Python committer) Date: 2019-09-30 05:35
Closed by the new asyncio stream API reversion in GH-16485 and GH-16482.
