* [3.11] GH-113214: Fix SSLProto exception handling in SSL-over-SSL scenarios ↵Miss Islington (bot)2023-12-211-1/+14
| | | | | | | | | | | (GH-113334) (#113340) When wrapped, `_SSLProtocolTransport._force_close(exc)` is called just like in the unwrapped scenario `_SelectorTransport._force_close(exc)` or `_ProactorBasePipeTransport._force_close(exc)` would be called, except here the exception needs to be passed through the `SSLProtocol._abort()` method, which didn't accept an exception object. This commit ensures that this path works, in the same way that the uvloop implementation of SSLProto passes on the exception (on which the current implementation of SSLProto is based).

* GH-95704: Don't suppress errors from tasks when TG is cancelled (GH-95761)Miss Islington (bot)2022-08-171-24/+30
| | | | | | | | | | | | | | | | When a task catches CancelledError and raises some other error, the other error should not silently be suppressed. Any scenario where a task crashes in cleanup upon cancellation will now result in an ExceptionGroup wrapping the crash(es) instead of propagating CancelledError and ignoring the side errors. NOTE: This represents a change in behavior (hence the need to change several tests). But it is only an edge case.
