* [3.12] GH-113214: Fix SSLProto exception handling in SSL-over-SSL scenarios ↵Miss Islington (bot)2023-12-211-7/+6
| | | | | | | | | | | (GH-113334) (#113339) 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).

* [3.12] gh-79033: Try to fix asyncio.Server.wait_closed() again (GH-111336) ↵Miss Islington (bot)2023-10-281-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#111424) gh-79033: Try to fix asyncio.Server.wait_closed() again (GH-111336) * Try to fix asyncio.Server.wait_closed() again I identified the condition that `wait_closed()` is intended to wait for: the server is closed *and* there are no more active connections. When this condition first becomes true, `_wakeup()` is called (either from `close()` or from `_detach()`) and it sets `_waiters` to `None`. So we just check for `self._waiters is None`; if it's not `None`, we know we have to wait, and do so. A problem was that the new test introduced in 3.12 explicitly tested that `wait_closed()` returns immediately when the server is *not* closed but there are currently no active connections. This was a mistake (probably a misunderstanding of the intended semantics). I've fixed the test, and added a separate test that checks exactly for this scenario. I also fixed an oddity where in `_wakeup()` the result of the waiter was set to the waiter itself. This result is not used anywhere and I changed this to `None`, to avoid a GC cycle. * Update Lib/asyncio/base_events.py --------- (cherry picked from commit 26553695592ad399f735d4dbaf32fd871d0bb1e1) Co-authored-by: Guido van Rossum <guido@python.org> Co-authored-by: Carol Willing <carolcode@willingconsulting.com>

| | | | | | | | | | (GH-110884) (#111412) - `ThreadedChildWatcher.close()` is now *officially* a no-op; `_join_threads()` never did anything. - Threads created by that class are now named `asyncio-waitpid-NNN`. - `test.test_asyncio.utils.TestCase.close_loop()` now waits for the child watcher's threads, but not forever; if a thread hangs, it raises `RuntimeError`.

They now remain in a consistent state after an exception is thrown, so subsequent operations can be performed correctly (if they are allowed).

Document it and adapt the test for that. Revert commit 282edd7b2a74c4dfe1bfe3c5b1d30f9c21d554d6. _child_watcher_callback() calls immediately _process_exited(): don't add an additional delay with call_soon(). The reverted change didn't make _process_exited() more determistic: it can still be called before pipe_connection_lost() for example.
