…ution (GH-136212) ContextDecorator and AsyncContextDecorator (and therefore @contextmanager and @asynccontextmanager used as decorators) now detect generator, coroutine, and asynchronous generator functions and emit a wrapper of the matching kind, so the context manager spans iteration or await rather than just the call that constructs the lazy object. Wrapped generators are explicitly closed when iteration ends. For asynchronous generator wrappers, values passed via asend() and exceptions via athrow() are not forwarded to the wrapped generator. AsyncContextDecorator now also accepts synchronous functions and generators, returning an asynchronous wrapper; ContextDecorator remains the recommended choice for those. inspect.isgeneratorfunction(), iscoroutinefunction(), and isasyncgenfunction() now return True for the decorated result when the input is of that kind. --------- Co-authored-by: Gregory P.

…king (GH-137196) Make _find_and_load() acquire the module locks for the full dotted-name chain (parent before child) when loading a nested module, so both threads contend on the same first lock and serialise instead of deadlocking. When acquiring a parent's lock would itself deadlock with another thread that is loading that parent (cross-package circular imports), the parent's lock is skipped and the partially-initialised parent is accepted -- the same policy _lock_unlock_module() already applies on the existing code path -- so concurrent circular imports that worked before continue to work.
