executables used to find the mac address, with /sbin and /usr/sbin as
fallbacks.
Issue #11508: Fixed uuid.getnode() and uuid.uuid1() on environment with
virtual interface. Original patch by Kent Frazier.
Issue #18784: The uuid module no more attempts to load libc via ctypes.CDLL,
if all necessary functions are already found in libuuid.
Patch by Evgeny Sologubov.
Issue #16102: Make uuid._netbios_getnode() work again on Python 3.
When running tests in subprocesses with the regrtest -j option, a bug
in Cocoa Tk can result in a Tcl segfault. Avoid the problem by forcing
Tk to fully initialize as an OS X gui process before destroying the
Tcl instance and creating another. (Original patch by Serhiy Storchaka)
Before, if a default was set on the parent parser, any default for that
variable set via set_defaults on a subparser would be ignored. Now
the subparser set_defaults is honored.
Patch by Jyrki Pullianinen.
It is unlikely anyone is using the fact that the dictionary returned
by the 'params' attribute was previously writable, but even if someone
is the API is provisional so this kind of change is acceptable (and
needed, to get the API "right" before it becomes official).
Patch by Stéphane Wirtel.

Since Python 3.5, socket.socketpair() is now also available on Windows.
Make csock blocking before calling the accept() method, and fix also a typo in
an error message.
Patch by Michel Albert. We don't normally do patches that just tweak
whitespace, but ipaddress is relatively new and the package maintainers
approved the patch.
* Don't call the garbage collector with an exception set: it causes an
assertion to fail in debug mode.
* Enhance also error handling if allocating an array for the executable list
failed.
* Add an unit test for 4 different errors in the _posixsubprocess module.
The test needs to be skipped if unicodedata is either part of the
main binary (a repackaging of cpython on Windows?) or has python
source (pypy?). PEP 3147 makes __file__ point to the .py source,
so we need to change the extension check from looking for the
old .pyc/.pyo to just looking for .py.
Note that this skip should never trigger on CPython itself, so
one could argue it should be dropped instead. But since it exists,
why risk breaking someone else's python.
Since EmailMessage is a provisional API we can fix API bugs in a
maintenance release, but I used a trick suggested by Serhiy to
maintain backward compatibility with 3.4.0/1.
There is a race condition in create_connection() used with wait_for() to have a
timeout. sock_connect() registers the file descriptor of the socket to be
notified of write event (if connect() raises BlockingIOError). When
create_connection() is cancelled with a TimeoutError, sock_connect() coroutine
gets the exception, but it doesn't unregister the file descriptor for write
event. create_connection() gets the TimeoutError and closes the socket.
If you call again create_connection(), the new socket will likely gets the same
file descriptor, which is still registered in the selector. When sock_connect()
calls add_writer(), it tries to modify the entry instead of creating a new one.
This issue was originally reported in the Trollius project, but the bug comes
from Tulip in fact (Trollius is based on Tulip):
https://bitbucket.org/enovance/trollius/issue/15/after-timeouterror-on-wait_for
This change fixes the race condition. It also makes sock_connect() more
reliable (and portable) is sock.connect() raises an InterruptedError.
Without this reset, starttls would fail if a connect/starttls was done after a
quit, because smtplib assumed the existing value of emspt_features was
accurate, but it gets reset when starttls completes (and the new value does
not contain the starttls capability, since tls is already started at that
point). (There may be additional places where this lack of reset was an
issue as well.)
Patch by Milan Oberkirch.
Don't raise a TimeoutError if we reached the timeout and the future completed
in the same iteration of the event loop. A side effect of the bug is that
Queue.get() looses items.
* PipeServer.close() now cancels the "accept pipe" future which cancels the
overlapped operation.
* Fix _SelectorTransport.__repr__() if the transport was closed
* Fix debug log in BaseEventLoop.create_connection(): get the socket object
from the transport because SSL transport closes the old socket and creates a
new SSL socket object. Remove also the _SelectorSslTransport._rawsock
attribute: it contained the closed socket (not very useful) and it was not
used.
* Issue #22063: socket operations (sock_recv, sock_sendall, sock_connect,
sock_accept) of the proactor event loop don't raise an exception in debug
mode if the socket are in blocking mode. Overlapped operations also work on
blocking sockets.
* Fix unit tests in debug mode: mock a non-blocking socket for socket
operations which now raise an exception if the socket is blocking.
* _fatal_error() method of _UnixReadPipeTransport and _UnixWritePipeTransport
now log all exceptions in debug mode
* Don't log expected errors in unit tests
* Tulip issue 200: _WaitHandleFuture._unregister_wait() now catchs and logs
exceptions.
* Tulip issue 200: Log errors in debug mode instead of simply ignoring them.
window is created for every test class.
Fixed Tkinter images copying operations in NoDefaultRoot mode.
Tcl command names generated for "after" callbacks now contains a name of
original function.
* _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
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).
terminal to not write the ANSI sequence "\033[1034h" into stdout. This sequence
is used on some terminal (ex: TERM=xterm-256color") to enable support of 8 bit
characters.
