Possible to add `_start_tls_compatible` attribute to `TCPTransport`?

• uvloop version: 0.19.0
• Python version: 3.10.7
• Platform: Linux
• Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Yes
• Does uvloop behave differently from vanilla asyncio? How?: Yes

aiohttp (3.9.1) keeps warning (falsely) about ^1

RuntimeWarning: An HTTPS request is being sent through an HTTPS proxy. This support for TLS in TLS is known to be disabled in the stdlib asyncio (Python <3.11). This is why you'll probably see an error in the log below.

It throws this warning because it's not able to find _start_tls_compatible property on the TCPTransport object (https://github.com/aio-libs/aiohttp/blob/v3.9.1/aiohttp/connector.py#L1054). The same property is present when asyncio is used which provides SelectorSocketTransport as the underlying transport. Is it possible to provide the _start_tls_compatible attribute on the TCPTransport which can help us avoid this warning?

Commencez par comparer le TCPTransport de uvloop avec le SelectorSocketTransport d’asyncio, puis consultez la référence du connecteur aiohttp liée dans l’issue pour comprendre comment _start_tls_compatible est vérifié. Le travail est terminé lorsque TCPTransport expose l’attribut de compatibilité et qu’aiohttp n’émet plus le faux avertissement TLS-in-TLS.
