- Issues #21936, #21163: Fix sporadic failures of
test_future_exception_never_retrieved()
- Handle.cancel() now clears references to callback and args
- In debug mode, repr(Handle) now contains the location where the Handle was
created.
- Tulip issue 185: Add a create_task() method to event loops. The create_task()
method can be overriden in custom event loop to implement their own task
class. For example, greenio and Pulsar projects use their own task class. The
create_task() method is now preferred over creating directly task using the
Task class.
- tests: fix a warning
- fix typo in the name of a test function
- Update AbstractEventLoop: add new event loop methods; update also the unit test
- 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()
Handle objects are created. Pass the traceback to call_exception_handler() in
the 'source_traceback' key.
The traceback is truncated to hide internal calls in asyncio, show only the
traceback from user code.
Add tests for the new source_traceback, and a test for the 'Future/Task
exception was never retrieved' log.
done: use the first line number of the code object instead of the current line
number of the generator frame.
The name of the coroutine is not enough because many coroutines may have the
same name. It's a common case in asyncio tests for example.
exception if the current loop is not None.

"The behavior that you can set the loop to None (and keep track of it
explicitly) is part of the spec, and this should still be supported even in
debug mode. The behavior that we raise an error if you are caught having
multiple active loops per thread is just a debugging heuristic, and it
shouldn't break code that follows the spec."
available bytes from the "self pipe", not only a single byte. This change
reduces the risk of having the pipe full and so getting the innocuous
"BlockingIOError: [Errno 11] Resource temporarily unavailable" message.
Python 3.5
- Drop __slots__ optimization of CoroWrapper to be able to set the __qualname__
attribute.
- Add tests on __name__, __qualname__ and __module__ of a coroutine function
and coroutine object.
- Fix test_tasks when run in debug mode (PYTHONASYNCIODEBUG env var set) on
Python 3.3 or 3.4
repr(Handle) is shorter for function: "foo" instead of "<function foo at
0x...>". It now also includes the source of the callback, filename and line
number where it was defined, if available.
repr(Task) now also includes the current position in the code, filename and
line number, if available. If the coroutine (generator) is done, the line
number is omitted and "done" is added.
Add BaseEventLoop._closed attribute and use it to check if the event loop was
closed or not, instead of checking different attributes in each subclass of
BaseEventLoop.
run_forever() and run_until_complete() methods now raise a RuntimeError('Event loop is
closed') exception if the event loop was closed.
BaseProactorEventLoop.close() now also cancels "accept futures".
Fix ResourceWarning: create_connection(), create_datagram_endpoint() and
create_unix_server() methods of event loop now close the newly created socket
on error.
loop in debug mode. Raise a RuntimeError if the event loop of the current
thread is different. The check should help to debug thread-safetly issue.

* Issue #159: Fix windows_utils.socketpair()
- Use "127.0.0.1" (IPv4) or "::1" (IPv6) host instead of "localhost", because
"localhost" may be a different IP address
- Reject also invalid arguments: only AF_INET/AF_INET6 with SOCK_STREAM (and
proto=0) are supported
* Reject add/remove reader/writer when event loop is closed.
* Fix ResourceWarning warnings
