GH-119866: Spill the stack around escaping calls. (GH-124392)
* Spill the evaluation around escaping calls in the generated interpreter and JIT. 

* The code generator tracks live, cached values so they can be saved to memory when needed.

* Spills the stack pointer around escaping calls, so that the exact stack is visible to the cycle GC.

GH-120804: Remove SafeChildWatcher, FastChildWatcher and MultiLoopChildWatcher from asyncio (#120805)
Remove SafeChildWatcher, FastChildWatcher and MultiLoopChildWatcher from asyncio. These child watchers have been deprecated since Python 3.12. The tests are also removed and some more tests will be added after the rewrite of child watchers.

gh-117722: Fix Stream.readuntil with non-bytes buffer objects (#117723)
gh-16429 introduced support for an iterable of separators in
Stream.readuntil. Since bytes-like types are themselves iterable, this
can introduce ambiguities in deciding whether the argument is an
iterator of separators or a singleton separator. In gh-16429, only 'bytes'
was considered a singleton, but this will break code that passes other
buffer object types.

Fix it by only supporting tuples rather than arbitrary iterables.

Closes gh-117722.

gh-114914: Avoid keeping dead StreamWriter alive (#115661)
In some cases we might cause a StreamWriter to stay alive even when the
application has dropped all references to it. This prevents us from
doing automatical cleanup, and complaining that the StreamWriter wasn't
properly closed.

Fortunately, the extra reference was never actually used for anything so
we can just drop it.

gh-114099: Add test exclusions to support running the test suite on iOS (#114889)
Add test annotations required to run the test suite on iOS (PEP 730).

The majority of the change involve annotating tests that use subprocess,
but are skipped on Emscripten/WASI for other reasons, and including
iOS/tvOS/watchOS under the same umbrella as macOS/darwin checks.

`is_apple` and `is_apple_mobile` test helpers have been added to
identify *any* Apple platform, and "any Apple platform except macOS",
respectively.

gh-111644: Fix asyncio test_unhandled_exceptions() (#111713)
Fix test_unhandled_exceptions() of test_asyncio.test_streams: break
explicitly a reference cycle.

Fix also StreamTests.tearDown(): the loop must not be closed
explicitly, but using set_event_loop() which takes care of shutting
down the executor with executor.shutdown(wait=True).
BaseEventLoop.close() calls executor.shutdown(wait=False).

gh-93453: No longer create an event loop in get_event_loop() (#98440)
asyncio.get_event_loop() now always return either running event loop or
the result of get_event_loop_policy().get_event_loop() call. The latter
should now raise an RuntimeError if no current event loop was set
instead of creating and setting a new event loop.

It affects also a number of asyncio functions and constructors which
call get_event_loop() implicitly: ensure_future(), shield(), gather(),
etc.

DeprecationWarning is no longer emitted if there is no running event loop but
the current event loop was set.

GH-94597: Deprecate child watcher getters and setters (#98215)
This is the next step for deprecating child watchers.

Until we've removed the API completely we have to use it, so this PR is mostly suppressing a lot of warnings when using the API internally.

Once the child watcher API is totally removed, the two child watcher implementations we actually use and need (Pidfd and Thread) will be turned into internal helpers.

gh-97983: Revert "Lay the foundation for further work in asyncio.test_streams: port server cases to IsolatedAsyncioTestCase" (#98015)
This PR reverts gh-93369 and gh-97896 because they've made asyncio tests unstable. After these PRs were merged, random GitHub action jobs of random commits started to fail unrelated tests and test framework methods.

The reverting is necessary because such shrapnel failures are a symptom of some underlying bug that must be found and fixed first.

I had a hope that it's a server overload because we already have extremely rare disc access errors. However, one and a half day passed, and the failures continue to emerge both in PRs and commits.

Affected issue: gh-93357.
First reported in https://github.com/python/cpython/pull/97940#issuecomment-1270004134.

* Revert "gh-93357: Port test cases to IsolatedAsyncioTestCase, part 2 (#97896)"

This reverts commit 09aea94d29.

* Revert "gh-93357: Start porting asyncio server test cases to IsolatedAsyncioTestCase (#93369)"

This reverts commit ce8fc186ac.

gh-79156: Add start_tls() method to streams API (#91453)
The existing event loop `start_tls()` method is not sufficient for
connections using the streams API. The existing StreamReader works
because the new transport passes received data to the original protocol.
The StreamWriter must then write data to the new transport, and the
StreamReaderProtocol must be updated to close the new transport
correctly.

The new StreamWriter `start_tls()` updates itself and the reader
protocol to the new SSL transport.
