* Rewrite importlib _get_module_lock(): it is now responsible to hold
the imp lock directly.
* _find_and_load() now holds the module lock to check if name is in
sys.modules to prevent a race condition
(cherry picked from commit 4f9a446f3f)
multiprocessing.Queue.join_thread() now waits until the thread
completes, even if the thread was started by the same process which
created the queue.
Fix the following warning which occurs randomly when running
test_handle_called_with_mp_queue of test_logging.QueueListenerTest:
Warning -- threading_cleanup() failed to cleanup -1 threads after 4 sec (count: 0, dangling: 1)
(cherry picked from commit 3b69d911c5)
If history-length is set in .inputrc, and the history file is double the
history size (or more), history_get(N) returns NULL, and python
segfaults. Fix that by checking for NULL return value.
It seems that the root cause is incorrect handling of bigger history in
readline, but Python should not segfault even if readline returns
unexpected value.
This issue affects only GNU readline. When using libedit emulation
system history size option does not work.
* In config, put dump test code in a function; run it and unittest in 'if __name__ == '__main__'.
* Add class config.ConfigChanges based on changes_class_v4.py on bpo issue.
* Add class test_config.ChangesTest, partly based on configdialog_tests_v1.py on bpo issue.
* Revise configdialog to use ConfigChanges, mostly as specified in tracker msg297804.
* Revise test_configdialog to match configdialog changes. All tests pass in both files.
* Remove configdialog functions unused or moved to ConfigChanges.

* bpo-30726: PCbuild _elementtree: remove duplicate defines (#2348)
bpo-30726, bpo-29591: libexpat 2.2.1 of Modules/expat/ now uses
a winconfig.h configuration file which already defines:
* XML_NS
* XML_DTD
* BYTEORDER=1234
* XML_CONTEXT_BYTES=1024
* HAVE_MEMMOVE
Remove these defines from PCbuild/_elementtree.vcxproj to prevent
compiler warnings.

* bpo-30726: Fix elementtree warnings on Windows due to expat upgrade (#2319)
* bpo-30726: Fix elementtree warnings on Windows
Caused by usage of `getenv` which should be safe. And a few integer
truncations which should also be ok.
* bpo-30726: Don't ignore libexpat warnings which haypo intends to fix upstream

(cherry picked from commit d32a059531)
The current regex based splitting produces a wrong result. For example::
http://abc#@def
Web browsers parse that URL as ``http://abc/#@def``, that is, the host
is ``abc``, the path is ``/``, and the fragment is ``#@def``.

* Fixes build scripts to find msbuild.exe and stop relying on vcvarsall.bat
Also fixes bdist_wininst.vcxproj to use correct version in generated name.

Leading whitespace was incorrectly dropped during folding of certain lines in the _header_value_parser's folding algorithm. This makes the whitespace handling code consistent.
FXpy doesn't have a Python 3 port and it only
supports Python 2.2 and older versions.

Avoid using Py_AddPendingCall from signal handler, to avoid calling signal-unsafe functions.
* Remove unused function
* Improve comments
* Add stress test
* Adapt for --without-threads

* bpo-30796: Fix failures in signal delivery stress test (#2488)
* bpo-30796: Fix failures in signal delivery stress test
setitimer() can have a poor minimum resolution on some machines,
this would make the test reach its deadline (and a stray signal
could then kill a subsequent test).
* Make sure to clear the itimer after the test
* bpo-29512: Add test.bisect, bisect failing tests (#2452)
Add a new "python3 -m test.bisect" tool to bisect failing tests.
It can be used to find which test method(s) leak references, leak
files, etc.
(cherry picked from commit 84d9d14a1f)
* bpo-30776: regrtest: reduce memleak false positive (#2484)
Only report a leak if each run leaks at least one memory block.
(cherry picked from commit beeca6e1e5)
* bpo-30280: asyncio now cleans up threads
asyncio base TestCase now uses threading_setup() and
threading_cleanup() of test.support to cleanup threads.
* asyncio: Fix TestBaseSelectorEventLoop cleanup
bpo-30280: TestBaseSelectorEventLoop of
test.test_asyncio.test_selector_events now correctly closes the event
loop: cleanup its executor to not leak threads.
Don't override the close() method of the event loop, only override
the_close_self_pipe() method.

test_unittest when hunting reference leaks using regrtest.
