Some built-in coroutine-like objects might not have __name__ or
__qualname__. A good example of such are 'asend', 'aclose' and
'athrow' coroutine methods of asynchronous generators.
- CoroWrapper.__del__() now reuses repr(CoroWrapper) to log the "... was never
yielded from" warning
- Improve CoroWrapper: copy also the qualified name on Python 3.4, not only on
Python 3.5+
- repr(Task) and repr(CoroWrapper) now also includes where these objects were
created. If the coroutine is not a generator (don't use "yield from"), use
the location of the function, not the location of the coro() wrapper.
- Fix create_task(): truncate the traceback to hide the call to create_task().
- Tulip issue #181: Faster create_connection(). Call directly
waiter.set_result() in the constructor of _ProactorBasePipeTransport and
_SelectorSocketTransport, instead of using of delaying the call with
call_soon().
- Cleanup iscoroutine()
* _UnixSubprocessTransport: fix file mode of stdin. Open stdin in write mode,
not in read mode
* Examples: close the event loop at exit
* More reliable CoroWrapper.__del__. If the constructor is interrupted by
KeyboardInterrupt or the coroutine objet is destroyed lately, some the
_source_traceback attribute doesn't exist anymore.
* repr(Task): include also the future the task is waiting for
- Sort imports
- Simplify/optimize iscoroutine(). Inline inspect.isgenerator(obj): replace it
with isinstance(obj, types.GeneratorType)
- CoroWrapper: check at runtime if Python has the yield-from bug #21209. If
Python has the bug, check if CoroWrapper.send() was called by yield-from to
decide if parameters must be unpacked or not.
- Fix "Task was destroyed but it is pending!" warning in
test_task_source_traceback()
