bpo-34275: Make IDLE calltips always visible on Mac. (GH-8639)
Some MacOS-tk combinations need .update_idletasks().
The call is both unneeded and innocuous on Linux and Windows.

bpo-27910: Update documentation of traceback module (GH-6116)
In the documentation for the traceback module, the definitions of functions
extract_tb(), format_list() and classmethod StackSummary.from_list()
mention the old style 4-tuples that these functions used to return or accept.
Since Python 3.5, however, they return or accept a FrameSummary object
instead of a 4-tuple, or a StackSummary object instead of a list of 4-tuples.
[3.6] bpo-33871: Fix os.sendfile(), os.writev(), os.readv(), etc. (GH-7931) (GH-8584)
* Fix integer overflow in os.readv(), os.writev() and in os.sendfile()
with headers or trailers arguments (on BSD-based OSes and MacOS).
* Fix sending the part of the file in os.sendfile() on MacOS.
Using the trailers argument could cause sending more bytes from
the input file than was specified.
bpo-29710: Clarify documentation for Bitwise binary operation (GH-1691)
Mathematically, bitwise operations on integers behave as if there were an
infinite number of sign bits. Pragmatically, that gives the same answer as
using one extra sign bit for the bitwise logical operations.

[3.6] bpo-29097: Forego fold detection on windows for low timestamp values (GH-2385) (GH-8498)
On Windows, passing a negative value to local results in an OSError because localtime_s on Windows does not support negative timestamps. Unfortunately this means that fold detection for timestamps between 0 and max_fold_seconds will result in this OSError since we subtract max_fold_seconds from the timestamp to detect a fold. However, since we know there haven't been any folds in the interval [0, max_fold_seconds) in any timezone, we can hackily just forego fold detection for this time range on Windows..

bpo-12743: Delete comment from marshal.rst (GH-8457)
Also, update the list of exceptions that may raised by PyMarshal_*
functions. We usually don't document exceptions raised by a
function, but in this case most of them were already documented
in C API and standard library documentation.

bpo-32663 Make SMTPUTF8SimTests run (GH-5314) (#8470)
Enable and fix SMTPUTF8SimTests in test_smtplib.
The tests for SMTPUTF8SimTests in test_smtplib.py were not actually
being run because test_smtplib was still using the 'test_main' pattern,
and the class was never added to test_main.
Additionally, one of the tests needed to be moved to the non-UTF8 server
class because it relies on the server not being UTF-8 compatible (and it
had a bug in in).

bpo-25094: Fix test_tools.test_sundry() on Windows (GH-8406)
When Python is installed on Windows, python -m test test_tools failed
because it tried to run Tools\scripts\2to3.py which requires an
argument. Skip this script. On other platforms or on Windows but when
run from source code (not installed), the script is called "2to3"
instead of "2to.py" and so was already skipped.
Increase the timeout: give timeout x 4 instead of timeout x 2 to
threads to wait until the Event is set, but reduce the sleep from 500
ms to 250 ms. So the test should be more reliable and faster!

test_signal.test_socket(): On Windows, sometimes even if the C signal handler
succeed to write the signal number into the write end of the socketpair, the
test fails with a BlockingIOError on the non-blocking read.recv(1) because the

[3.6] bpo-34066: Disabled interruption before SETUP_WITH and BEFORE_ASYNC_WITH. (GH-8159) (GH-8198)

in "with open()".

[3.6] bpo-33899: Make tokenize module mirror end-of-file is end-of-line behavior (GH-7891) (GH-8134)
Most of the change involves fixing up the test suite, which previously made
the assumption that there wouldn't be a new line if the input didn't end in
one.
Result of function interpreter_requires_environment() depends on os.environ.
This was not covered by the tests, leading to fail when PYTHONHOME was set.

Fix test_forkserver_sigkill() of test_multiprocessing_forkserver:
give more time to the first child process to complete, double the
sleep in the parent process.
Reduce also the child process sleep from 1000 ms to 500 ms, to not change
the total duration of the test.

bpo-33735: Fix test_multiprocessing random failure (GH-8059)
When hunting memory leaks using -R 3:3, test_imap_unordered() of
test_multiprocessing leaks randomly a few memory blocks. It is a
false alarm: when testing using -R 3:20 for example, no leak is
detected.
Modify test_imap_unordered() to be closer to test_imap():
* Only test 10 numbers instead of 1000: it's a pool of 4 processes, so
10 is enough to test at least one number per process
* Use chunksize=100 instead of chunksize=53 to mimick test_imap()

[3.6] bpo-32568: make select.epoll() and its docs consistent (GH-7840) (GH-8025)
* `flags` is indeed deprecated, but there is a validation on its value for
backwards compatibility reasons. This adds mention of this in the docs.
* The docs say that `sizehint` is deprecated and ignored, but it is still
used when `epoll_create1()` is unavailable. This adds mention of this in
the docs.
* `sizehint=-1` is acceptable again, and is replaced with `FD_SETSIZE-1`.
This is needed to have a default value available at the Python level,
since `FD_SETSIZE` is not exposed to Python. (see: bpo-31938)
* Reject `sizehint=0` since it is invalid to pass on to `epoll_create()`.
