Patch by Milan Oberkirch, developed as part of his 2014 GSOC project.
Note that this also fixes a bug in mock_socket ('getpeername' was returning a
simple string instead of the tuple required for IPvX protocols), a bug in
DebugServer with respect to handling binary data (should have been fixed when
decode_data was introduced, but wasn't found until this patch was written),
and a long-standing bug in DebugServer (it was printing an extra blank line at
the end of the displayed message text).
`mkdir -p` and `os.makedirs()` functionality. When true, ignore
FileExistsErrors. Patch by Berker Peksag.
(With minor cleanups, additional tests, doc tweaks, etc. by Barry)
Also:
* Remove some unused imports in test_pathlib.py reported by pyflakes.
- Close#22063: socket operations (socket,recv, sock_sendall, sock_connect,
sock_accept) now raise an exception in debug mode if sockets are in blocking
mode.
- asyncio: Use the new os.set_blocking() function of Python 3.5 if available
* _WaitHandleFuture.cancel() now notify IocpProactor through the overlapped
object that the wait was cancelled.
* Optimize IocpProactor.wait_for_handle() gets the result if the wait is
signaled immediatly.
* Enhance representation of Future and Future subclasses
- Add "created at filename:lineno" in the representation
- Add Future._repr_info() method which can be more easily overriden than
Future.__repr__(). It should now be more easy to enhance Future
representation without having to modify each subclass. For example,
_OverlappedFuture and _WaitHandleFuture get the new "created at" information.
- Use reprlib to format Future result, and function arguments when formatting a
callback, to limit the length of the representation.
* Fix repr(_WaitHandleFuture)
* _WaitHandleFuture and _OverlappedFuture: hide frames of internal calls in the
source traceback.
* Cleanup ProactorIocp._poll(): set the timeout to 0 after the first call to
GetQueuedCompletionStatus()
* test_locks: close the temporary event loop and check the condition lock
* Remove workaround in test_futures, no more needed
* _WaitHandleFuture.cancel() now notify IocpProactor through the overlapped
object that the wait was cancelled.

Improve stability of the proactor event loop, especially operations on
overlapped objects:
* Tulip issue 195: Don't call UnregisterWait() twice if a _WaitHandleFuture is
cancelled twice to fix a crash.
* IocpProactor.close(): cancel futures to cancel overlapped operations, instead
of cancelling directly overlapped operations. Future objects may not call
ov.cancel() if the future was cancelled or if the overlapped was already
cancelled. The cancel() method of the future may also catch exceptions. Log
also errors on cancellation.
* tests: rename "f" to "fut"
* Add a __repr__() method to IocpProactor
* Add a destructor to IocpProactor which closes it
* _OverlappedFuture.cancel() doesn't cancel the overlapped anymore if it is
done: if it is already cancelled or completed. Log also an error if the
cancellation failed.
* Add the address of the overlapped object in repr(_OverlappedFuture)
* _OverlappedFuture truncates the source traceback to hide the call to the
parent constructor (useless in debug).

ignores BlockingIOError exceptions. Initial patch written by Xavier de Gaye.
Document also in asyncore documentation that recv() may raise BlockingIOError.

Adds `load_package_tests` function to test.support, uses it in test_asyncio,
test_email, test_json, test_tools, test_importlib and all test_importlib
sub-packages to implement test discovery.
* Issue #19811, #22022: test_pathlib uses support.rmtree() instead of
shutil.rmtree() to remove the temporary directory.
* Issue #19629: Fix support.rmtree(), use os.lstat() to check if the file is a
directory, not os.path.isdir()
- Use _testcapi.raise_signal() in test_signal
- close also os.pipe() file descriptors in some test_signal tests where they
were not closed properly
- Remove faulthandler._sigill() and faulthandler._sigbus(): reuse
_testcapi.raise_signal() in test_faulthandler
Since Python 3.3, the C signal handler writes the signal number into the wakeup
file descriptor and then schedules the Python call using Py_AddPendingCall().
asyncio uses the wakeup file descriptor to wake up the event loop, and relies
on Py_AddPendingCall() to schedule the final callback with call_soon().
If the C signal handler is called in a thread different than the thread of the
event loop, the loop is awaken but Py_AddPendingCall() was not called yet. In
this case, the event loop has nothing to do and go to sleep again.
Py_AddPendingCall() is called while the event loop is sleeping again and so the
final callback is not scheduled immediatly.
This patch changes how asyncio handles signals. Instead of relying on
Py_AddPendingCall() and the wakeup file descriptor, asyncio now only relies on
the wakeup file descriptor. asyncio reads signal numbers from the wakeup file
descriptor to call its signal handler.
