Cython will, in the right circumstances, offer a MethodType instance
where im_func is a builtin function. Any instance of MethodType is
automatically assumed to be a Python-defined function (more
specifically, a function that has an inspectable signature), but
_set_signature was still conservative in its assumptions. As a result
_set_signature would return early with None instead of a mock since
the im_func had no inspectable signature. This causes problems
deeper inside mock, as _set_signature is assumed to _always_
return a mock, and nothing checked its return value.
In similar corner cases, autospec will simply not check the spec of the
function, so _set_signature is amended to now return early with the
original, not-wrapped mock object.

(cherry picked from commit 856cbcc12f)
Use sys.modules.get() in the "with _ModuleLockManager(name):" block
to protect the dictionary key with the module lock and use an atomic
get to prevent race condition.
Remove also _bootstrap._POPULATE since it was unused
(_bootstrap_external now has its own _POPULATE object), add a new
_SENTINEL object instead.
(cherry picked from commit e72b1359f8)
When running the test suite using --use=all / -u all, exclude tzdata
since it makes test_datetime too slow (15-20 min on some buildbots)
which then times out on some buildbots.
-u tzdata must now be enabled explicitly, -u tzdata or -u all,tzdata,
to run all test_datetime tests.
Fix also regrtest command line parser to allow passing -u
extralargefile to run test_zipfile64.
Travis CI: remove -tzdata. Replace -u all,-tzdata,-cpu with -u all,-cpu since tzdata is now excluded from -u all.

instead of failing with SystemError.
Relative import from non-package now fails with ImportError rather than
SystemError.

The will help writing dialog improvements and splitting the class into multiple classes.

(cherry picked from commit 36329a4)
* 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.

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.
* [3.6] bpo-30703: Improve signal delivery (GH-2415)
* Improve signal delivery
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
* Add second stress test
* Add NEWS blurb
* Address comments @haypo.
(cherry picked from commit c08177a1cc)
* 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.

bpo-11798, bpo-16662, bpo-16935, bpo-30813: Skip
test_discover_with_module_that_raises_SkipTest_on_import() and
test_discover_with_init_module_that_raises_SkipTest_on_import() of
test_unittest when hunting reference leaks using regrtest.

Split TextViewer class into ViewWindow, ViewFrame, and TextFrame classes so that instances
of the latter two can be placed with other widgets within a multiframe window.

(cherry picked from commit 42bc8be)
* Clear potential ref cycle between Process and Process target
Besides Process.join() not being called, this was an indirect cause of bpo-30775.
The threading module already does this.
* Add issue reference.
(cherry picked from commit 79d37ae979)
Based on patch by Victor Stinner.
Add private C API function _PyUnicode_AsUnicode() which is similar to
PyUnicode_AsUnicode(), but checks for null characters..
(cherry picked from commit f7eae0adfc)
* Add 'parens' style to highlight both opener and closer.
* Make 'default' style, which is not default, a synonym for 'opener'.
* Make time-delay work the same with all styles.
* Add help for config dialog extensions tab, including parenmatch.
* Add new tests.
Original patch by Charles Wohlganger.
(cherry picked from commit fae2c35)
* bpo-30523: regrtest --list-cases --match (#2401)
* regrtest --list-cases now supports --match and --match-file options.
Example: ./python -m test --list-cases -m FileTests test_os
* --list-cases now also sets support.verbose to False to prevent
messages to stdout when loading test modules.
* Add support._match_test() private function.
(cherry picked from commit ace56d5836)
* bpo-30764: regrtest: add --fail-env-changed option (#2402)
* bpo-30764: regrtest: change exit code on failure
* Exit code 2 if failed tests ("bad")
* Exit code 3 if interrupted
* bpo-30764: regrtest: add --fail-env-changed option
If the option is set, mark a test as failed if it alters the
environment, for example if it creates a file without removing it.
(cherry picked from commit 63f54c6893)
* bpo-30776: reduce regrtest -R false positives (#2422)
* Change the regrtest --huntrleaks checker to decide if a test file
leaks or not. Require that each run leaks at least 1 reference.
* Warmup runs are now completely ignored: ignored in the checker test
and not used anymore to compute the sum.
* Add an unit test for a reference leak.
Example of reference differences previously considered a failure
(leak) and now considered as success (success, no leak):
[3, 0, 0]
[0, 1, 0]
[8, -8, 1]
