bpo-40280: Skip socket, fork, subprocess tests on Emscripten (GH-31986)
...
- Add requires_fork and requires_subprocess to more tests
- Skip extension import tests if dlopen is not available
- Don't assume that _testcapi is a shared extension
- Skip a lot of socket tests that don't work on Emscripten
- Skip mmap tests, mmap emulation is incomplete
- venv does not work yet
- Cannot get libc from executable
The "entire" test suite is now passing on Emscripten with EMSDK from git head (91 suites are skipped).

bpo-44594: fix (Async)ExitStack handling of __context__ (gh-27089)
...
* bpo-44594: fix (Async)ExitStack handling of __context__
Make enter_context(foo()) / enter_async_context(foo()) equivalent to
`[async] with foo()` regarding __context__ when an exception is raised.
Previously exceptions would be caught and re-raised with the wrong
context when explicitly overriding __context__ with None.

bpo-41229: Update docs for explicit aclose()-required cases and add contextlib.aclosing() method (GH-21545)
...
This is a PR to:
* Add `contextlib.aclosing` which ia analogous to `contextlib.closing` but for async-generators with an explicit test case for [bpo-41229]()
* Update the docs to describe when we need explicit `aclose()` invocation.
which are motivated by the following issues, articles, and examples:
* [bpo-41229]()
* https://github.com/njsmith/async_generator
* https://vorpus.org/blog/some-thoughts-on-asynchronous-api-design-in-a-post-asyncawait-world/#cleanup-in-generators-and-async-generators
* https://www.python.org/dev/peps/pep-0533/
* https://github.com/achimnol/aiotools/blob/ef7bf0cea7af/src/aiotools/context.py#L152
Particuarly regarding [PEP-533](https://www.python.org/dev/peps/pep-0533/ ), its acceptance (`__aiterclose__()`) would make this little addition of `contextlib.aclosing()` unnecessary for most use cases, but until then this could serve as a good counterpart and analogy to `contextlib.closing()`. The same applies for `contextlib.closing` with `__iterclose__()`.
Also, still there are other use cases, e.g., when working with non-generator objects with `aclose()` methods.

Deprecated passing the following arguments as keyword arguments:
- "func" in functools.partialmethod(), weakref.finalize(),
profile.Profile.runcall(), cProfile.Profile.runcall(),
bdb.Bdb.runcall(), trace.Trace.runfunc() and
curses.wrapper().
- "function" in unittest.addModuleCleanup() and
unittest.TestCase.addCleanup().
- "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor
and concurrent.futures.ProcessPoolExecutor.
- "callback" in contextlib.ExitStack.callback(),
contextlib.AsyncExitStack.callback() and
contextlib.AsyncExitStack.push_async_callback().
- "c" and "typeid" in the create() method of multiprocessing.managers.Server
and multiprocessing.managers.SharedMemoryServer.
- "obj" in weakref.finalize().
Also allowed to pass arbitrary keyword arguments (even "self" and "func")
if the above arguments are passed as positional argument.
