LoadLibrary, GetProcAddress, FreeLibrary and GetModuleHandle acquire the system loader lock. Calling these while holding the GIL will cause a deadlock on the rare occasion that another thread is detaching and needs to destroy its thread state at the same time.

-For Python.3.7, python.org currently provides two installer variants for download: one that installs a 
-\i 64-bit-only 
-\i0 Python capable of running on 
-\i macOS 10.9 (Mavericks)
-\i0  or later; and one that installs a 
-\i 64-bit/32-bit Intel
-\i0  Python capable of running on 
-\i macOS 10.6 (Snow Leopard)
-\i0  or later.  (This ReadMe was installed with the 
-\i $MACOSX_DEPLOYMENT_TARGET
-\i0  variant.)  If you are running on macOS 10.9 or later and if you have no need for compatibility with older systems, use the 10.9 variant.  Use the 10.6 variant if you are running on macOS 10.6 through 10.8 or if you want to produce standalone applications that can run on systems from 10.6.  The Pythons installed by these installers are built with private copies of some third-party libraries not included with or newer than those in macOS itself.  The list of these libraries varies by installer variant and is included at the end of the License.rtf file.

summary:

bpo-35872 and bpo-35873: Clears __PYVENV_LAUNCHER__ variable (GH-11745)

After reading __PYVENV_LAUNCHER__ we now set sys._base_executable value for later use.
Make the same changes for macOS to avoid extra platform checks.

+Fix lru_cache() errors arising in recursive, reentrant, or multi-threaded
+code. These errors could result in orphan links and in the cache being
+trapped in a state with fewer than the specified maximum number of links.
+Fix handling of negative maxsize which should have been treated as zero. Fix
+errors in toggling the "full" status flag. Fix misordering of links when
+errors are encountered.  Sync-up the C code and pure Python code for the
+space saving path in functions with a single positional argument. In this
+common case, the space overhead of an lru cache entry is reduced by almost
+half.  Fix counting of cache misses. In error cases, the miss count was out
+of sync with the actual number of times the underlying user function was
+called.

+``_abc`` module is added.  It is a speedup module with C implementations for
+various functions and methods in ``abc``.  Creating an ABC subclass and
+calling ``isinstance`` or ``issubclass`` with an ABC subclass are up to 1.5x
+faster. In addition, this makes Python start-up up to 10% faster.
+
+Note that the new implementation hides internal registry and caches,
+previously accessible via private attributes ``_abc_registry``,
+``_abc_cache``, and ``_abc_negative_cache``.  There are three debugging
+helper methods that can be used instead ``_dump_registry``,
+``_abc_registry_clear``, and ``_abc_caches_clear``.

+``_abc`` module is added.  It is a speedup module with C implementations for
+various functions and methods in ``abc``.  Creating an ABC subclass and
+calling ``isinstance`` or ``issubclass`` with an ABC subclass are up to 1.5x
+faster. In addition, this makes Python start-up up to 10% faster.
+
+Note that the new implementation hides internal registry and caches,
+previously accessible via private attributes ``_abc_registry``,
+``_abc_cache``, and ``_abc_negative_cache``.  There are three debugging
+helper methods that can be used instead ``_dump_registry``,
+``_abc_registry_clear``, and ``_abc_caches_clear``.

bpo-35872 and bpo-35873: Clears __PYVENV_LAUNCHER__ variable (GH-11745)

After reading __PYVENV_LAUNCHER__ we now set sys._base_executable value for later use.
Make the same changes for macOS to avoid extra platform checks.

Subject: [Python-checkins] bpo-32417: Make timedelta arithmetic respect
 subclasses (#10902)
Message-ID: <mailman.22.1549309331.32200.python-checkins@python.org>

https://github.com/python/cpython/commit/89427cd0feae25bbc8693abdccfa6a8c81a2689c
commit: 89427cd0feae25bbc8693abdccfa6a8c81a2689c
branch: master
author: Paul Ganssle <pganssle at users.noreply.github.com>
committer: Alexander Belopolsky <abalkin at users.noreply.github.com>
date: 2019-02-04T14:42:04-05:00
summary:

bpo-32417: Make timedelta arithmetic respect subclasses (#10902)

* Make timedelta return subclass types

Previously timedelta would always return the `date` and `datetime`
types, regardless of what it is added to. This makes it return
an object of the type it was added to.

* Add tests for timedelta arithmetic on subclasses

* Make pure python timedelta return subclass types

* Add test for fromtimestamp with tz argument

* Add tests for subclass behavior in now

* Add news entry.

Fixes:
bpo-32417
bpo-35364

* More descriptive variable names in tests

Addresses Victor's comments

summary:

bpo-35321: Set the spec origin to frozen in frozen modules (#11732)

* bpo-35321: Set the spec origin to frozen in frozen modules

This fix correctly sets the spec origin to
"frozen" for the _frozen_importlib module. Note that the
origin was already correctly set in _frozen_importlib_external.

* ?? Added by blurb_it.

summary:

bpo-24209: In http.server script, rely on getaddrinfo to bind to preferred address based on the bind parameter. (#11767)

In http.server script, rely on getaddrinfo to bind to preferred address based on the bind parameter.

As a result, now IPv6 is used as the default (including IPv4 on dual-stack systems). Enhanced tests.

following methods:

- WeakValueDictionary.copy()
- WeakValueDictionary.__deepcopy__()
- WeakKeyDictionary.copy()
- WeakKeyDictionary.__deepcopy__()

summary:

bpo-35615: Fix crashes when copying a Weak{Key,Value}Dictionary. (GH-11384) (GH-11785)

Protect dict iterations by wrapping them with _IterationGuard in the
following methods:

- WeakValueDictionary.copy()
- WeakValueDictionary.__deepcopy__()
- WeakKeyDictionary.copy()
- WeakKeyDictionary.__deepcopy__()

bpo-35903: Use autoconfig to probe for shm_open() and shm_unlink(). (#11765)

Use autoconfig to probe for shm_open() and shm_unlink().  Set SHM_NEEDS_LIBRT if we must
link with librt to get the shm_* functions.  Change setup.py to use the autoconfig defines.  These
changes should make it more likely that _multiprocessing/posixshmem.c gets built correctly on
different platforms.

-    # Notes:
-    # - The hash of tuples is deterministic: if the test passes once on a given

-    #   test_hash functions below should be interpreted assuming that the
-    #   hashes are random.
-    # - Due to the structure in the testsuite inputs, collisions are not
-    #   independent. For example, if hash((a,b)) == hash((c,d)), then also
-    #   hash((a,b,x)) == hash((c,d,x)). But the quoted probabilities assume
-    #   independence anyway.
-    # - We limit the hash to 32 bits in the tests to have a good test on
-    #   64-bit systems too. Furthermore, this is also a sanity check that the
-    #   lower 32 bits of a 64-bit hash are sufficiently random too.

+# Notes on testing hash codes.  The primary thing is that Python doesn't
+# care about "random" hash codes.  To the contrary, we like them to be
+# very regular when possible, so that the low-order bits are as evenly
+# distributed as possible.  For integers this is easy: hash(i) == i for
+# all not-huge i except i==-1.
+#
+# For tuples of mixed type there's really no hope of that, so we want
+# "randomish" here instead.  But getting close to pseudo-random in all
+# bit positions is more expensive than we've been willing to pay for.
+#
+# We can tolerate large deviations from random - what we don't want is
+# catastrophic pileups on a relative handful of hash codes.  The dict
+# and set lookup routines remain effective provided that full-width hash
+# codes for not-equal objects are distinct.
+#
+# So we compute various statistics here based on what a "truly random"
+# hash would do, but don't automate "pass or fail" based on those
+# results.  Instead those are viewed as inputs to human judgment, and the
+# automated tests merely ensure we get the _same_ results across
+# platforms.  In fact, we normally don't bother to run them at all -
+# set RUN_ALL_HASH_TESTS to force it.
+#
+# When global JUST_SHOW_HASH_RESULTS is True, the tuple hash statistics
+# are just displayed to stdout.  A typical output line looks like:
+#
+# old tuple test; 32-bit upper hash codes; \
+#             pileup 49 mean 7.4 coll 52 z +16.4
+#
+# "old tuple test" is just a string name for the test being run.
+#
+# "32-bit upper hash codes" means this was run under a 64-bit build and
+# we've shifted away the lower 32 bits of the hash codes.
+#
+# "pileup" is 0 if there were no collisions across those hash codes.
+# It's 1 less than the maximum number of times any single hash code was
+# seen.  So in this case, there was (at least) one hash code that was
+# seen 50 times:  that hash code "piled up" 49 more times than ideal.
+#
+# "mean" is the number of collisions a perfectly random hash function
+# would have yielded, on average.
+#
+# "coll" is the number of collisions actually seen.
+#
+# "z" is "coll - mean" divided by the standard deviation of the number
+# of collisions a perfectly random hash function would suffer.  A
+# positive value is "worse than random", and negative value "better than
+# random".  Anything of magnitude greater than 3 would be highly suspect
+# for a hash function that claimed to be random.  It's essentially
+# impossible that a truly random function would deliver a result 16.4
+# sdevs "worse than random".
+#
+# But we don't care here!  That's why the test isn't coded to fail.
+# Knowing something about how the high-order hash code bits behave
+# provides insight, but is irrelevant to how the dict and set lookup
+# code performs.  The low-order bits are much more important to that,
+# and on the same test those did "just like random":
+#
+# old tuple test; 32-bit lower hash codes; \
+#            pileup 1 mean 7.4 coll 7 z -0.2
+#
+# So there are always tradeoffs to consider.  For another:
+#
+# 0..99 << 60 by 3; 32-bit hash codes; \
+#            pileup 0 mean 116.4 coll 0 z -10.8
+#
+# That was run under a 32-bit build, and is spectacularly "better than
+# random".  On a 64-bit build the wider hash codes are fine too:
+#
+# 0..99 << 60 by 3; 64-bit hash codes; \
+#             pileup 0 mean 0.0 coll 0 z -0.0
+#
+# but their lower 32 bits are poor:
+#
+# 0..99 << 60 by 3; 32-bit lower hash codes; \
+#             pileup 1 mean 116.4 coll 324 z +19.2
+#
+# In a statistical sense that's waaaaay too many collisions, but (a) 324
+# collisions out of a million hash codes isn't anywhere near being a
+# real problem; and, (b) the worst pileup on a single hash code is a measly
+# 1 extra.  It's a relatively poor case for the tuple hash, but still
+# fine for practical use.
+#
+# This isn't, which is what Python 3.7.1 produced for the hashes of
+# itertools.product([0, 0.5], repeat=18).  Even with a fat 64-bit
+# hashcode, the highest pileup was over 16,000 - making a dict/set
+# lookup on one of the colliding values thousands of times slower (on
+# average) than we expect.

+The ``repr`` function is used for interactive echo of expression
+values.  It returns an altered version of the input string in which
+control codes, some BMP codepoints, and all non-BMP codepoints are
+replaced with escape codes. As demonstrated above, it allows one to
+identify the characters in a string, regardless of how they are displayed.
 
 Normal and error output are generally kept separate (on separate lines)
 from code input and each other.  They each get different highlight colors.

summary:

bpo-35378: Fix multiprocessing.Pool references (GH-11627)

Changes in this commit:

1. Use a _strong_ reference between the Pool and associated iterators
2. Rework PR #8450 to eliminate a cycle in the Pool.

There is no test in this commit because any test that automatically tests this behaviour needs to eliminate the pool before joining the pool to check that the pool object is garbaged collected/does not hang. But doing this will potentially leak threads and processes (see https://bugs.python.org/issue35413).

+Fix a reference issue inside :class:`multiprocessing.Pool` that caused
+the pool to remain alive if it was deleted without being closed or

+iterators so the pool does not get destroyed if a pool iterator is

bpo-35961: Fix a crash in slice_richcompare() (GH-11830)

Fix a crash in slice_richcompare(): use strong references rather than
stolen references for the two temporary internal tuples.

The crash (or assertion error) occurred if a garbage collection
occurred during slice_richcompare(), especially while calling
PyObject_RichCompare(t1, t2, op).

bpo-35961: Fix a crash in slice_richcompare() (GH-11830)


Fix a crash in slice_richcompare(): use strong references rather than
stolen references for the two temporary internal tuples.

The crash (or assertion error) occurred if a garbage collection
occurred during slice_richcompare(), especially while calling
PyObject_RichCompare(t1, t2, op).
(cherry picked from commit dcb68f47f74b0cc8a1896d4a4c5a6b83c0bbeeae)

summary:

bpo-35976: Enable Windows projects to build with platform ARM32 (GH-11825)

This change adds the necessary items to the build projects to avoid erroring out right at the start. It does not add _support_ for targeting Windows on ARM32, but is a necessary prerequisite for adding it.

bpo-35633: test_lockf() fails with "PermissionError: [Errno 13] Permission denied" on AIX (GH-11424)



[bpo-35633](https://bugs.python.org/issue35633): Fix a test regression introduced with [bpo-35189](https://bugs.python.org/issue35189) (PEP 475: fnctl functions are not retried if interrupted (EINTR)).

Not only a blocking IO error needs to be ignored - permission errors also need to be ignored.

p.s. - iirc as a "test" only correction a NEWS item is not required. If this is not correct - just mention, and I'll add a NEWS blurb.

Subject: [Python-checkins] [2.7] bpo-28043: improved default settings for
 SSLContext (GH-10608)
Message-ID: <mailman.42.1550240660.2821.python-checkins@python.org>

https://github.com/python/cpython/commit/b8eaec697a2b5d9d2def2950a0aa50e8ffcf1059
commit: b8eaec697a2b5d9d2def2950a0aa50e8ffcf1059
branch: 2.7
author: stratakis <cstratak at redhat.com>
committer: Victor Stinner <vstinner at redhat.com>

summary:

[2.7] bpo-28043: improved default settings for SSLContext (GH-10608)

The options OP_NO_COMPRESSION, OP_CIPHER_SERVER_PREFERENCE,
OP_SINGLE_DH_USE, OP_SINGLE_ECDH_USE, OP_NO_SSLv2 (except
for PROTOCOL_SSLv2), and OP_NO_SSLv3 (except for PROTOCOL_SSLv3)
are set by default. The initial cipher suite list contains only
HIGH ciphers, no NULL ciphers and MD5 ciphers (except for PROTOCOL_SSLv2).

(cherry picked from commit 358cfd426ccc0fcd6a7940d306602138e76420ae)

[2.7] bpo-32947: Fixes for TLS 1.3 and OpenSSL 1.1.1 (GH-8761) (GH-11876)

Backport of TLS 1.3 related fixes from 3.7.

Misc fixes and workarounds for compatibility with OpenSSL 1.1.1 from git
master and TLS 1.3 support. With OpenSSL 1.1.1, Python negotiates TLS 1.3 by
default. Some test cases only apply to TLS 1.2.

OpenSSL 1.1.1 has added a new option OP_ENABLE_MIDDLEBOX_COMPAT for TLS
1.3. The feature is enabled by default for maximum compatibility with
broken middle boxes. Users should be able to disable the hack and CPython's test suite needs
it to verify default options

bpo-35931: Gracefully handle SyntaxError in pdb debug command (GH-11782)



Previously, `debug print(` would cause the interpreter to exit on a SyntaxError whereas `print(` would properly display the error and return to the pdb prompt.

This patch fixes this by pre-compiling the code before passing it to `Pdb.run`.

commit: 38f11cc3f62db11a4a24354bd06273322ac91afa

summary:

bpo-1054041: Exit properly after an uncaught ^C. (#11862)

* bpo-1054041: Exit properly by a signal after a ^C.

An uncaught KeyboardInterrupt exception means the user pressed ^C and
our code did not handle it.  Programs that install SIGINT handlers are
supposed to reraise the SIGINT signal to the SIG_DFL handler in order
to exit in a manner that their calling process can detect that they
died due to a Ctrl-C.  https://www.cons.org/cracauer/sigint.html

After this change on POSIX systems

 while true; do python -c 'import time; time.sleep(23)'; done

can be stopped via a simple Ctrl-C instead of the shell infinitely
restarting a new python process.

What to do on Windows, or if anything needs to be done there has not
yet been determined.  That belongs in its own PR.

TODO(gpshead): A unittest for this behavior is still needed.

* Do the unhandled ^C check after pymain_free.

* Return STATUS_CONTROL_C_EXIT on Windows.

* Fix ifdef around unistd.h include.

* ?? Added by blurb_it.

* Add STATUS_CTRL_C_EXIT to the os module on Windows

* Add unittests.

* Don't send CTRL_C_EVENT in the Windows test.

It was causing CI systems to bail out of the entire test suite.

See https://dev.azure.com/Python/cpython/_build/results?buildId=37980
for example.

* Correct posix test (fail on macOS?) check.

* STATUS_CONTROL_C_EXIT must be unsigned.

* Improve the error message.

* test typo :)

* Skip if the bash version is too old.

...and rename the windows test to reflect what it does.

* min bash version is 4.4, detect no bash.

* restore a blank line i didn't mean to delete.

* PyErr_Occurred() before the Py_DECREF(co);

* Don't add os.STATUS_CONTROL_C_EXIT as a constant.

* Update the Windows test comment.

* Refactor common logic into a run_eval_code_obj fn.

bpo-36013: delete fragile interactive shell SIGINT test (GH-11902)

It makes the existing smaller test more readable and robust at the same time.

The execution of a shell in interactive mode from CI and buildbot test automation wasn't working out.  What would work locally in our terminals would only work within a fraction of automation systems.  The integration test was a nice to have.  painful.  deleting. :)

bpo-34720: Fix test_importlib.test_bad_traverse for AIX (GH-9391)



Fix  Modules/_testmultiphase.c so that it exits with non-zero status on AIX just as other systems do (non zero exit status, e.g. as result of a segmentation fault) when a NULL pointer is accessed for data.

bpo-35992: Use PySequence_GetItem only if sq_item is not NULL (GH-11857)

Not using `__class_getitem__()` fallback if there is a non-subcriptable metaclass was caused by a certain asymmetry between how `PySequenceMethods` and `PyMappingMethods` are used in `PyObject_GetItem`. This PR removes this asymmetry. No tests failed, so I assume it was not intentional.

The error message emitted when returning invalid types from __fspath__ in interfaces that allow passing PathLike objects has been improved and now it does explain the origin of the error.

summary:

bpo-35798: Add test.support.check_syntax_warning(). (#11895)

It checks that a SyntaxWarning is raised when compile specified
statement, that it is raised only once, that it is converted to
a SyntaxError when raised as exception, and that both warning and
exception objects have corresponding attributes.

@@ -997,9 +997,27 @@ To convert, e.g., the number 144 to the string '144', use the built-in type
 constructor :func:`str`.  If you want a hexadecimal or octal representation, use
 the built-in functions :func:`hex` or :func:`oct`.  For fancy formatting, see
 the :ref:`formatstrings` section, e.g. ``"{:04d}".format(144)`` yields
-``'0144'`` and ``"{:.3f}".format(1/3)`` yields ``'0.333'``.  You may also use
-:ref:`the % operator <string-formatting>` on strings.  See the library reference
-manual for details.
+``'0144'`` and ``"{:.3f}".format(1.0/3.0)`` yields ``'0.333'``. In Python 2, the
+division (/) operator returns the floor of the mathematical result of division
+if the arguments are ints or longs, but it returns a reasonable approximation of
+the division result if the arguments are floats or complex::
+
+   >>> print('{:.3f}'.format(1/3))
+   0.000
+   >>> print('{:.3f}'.format(1.0/3))
+   0.333
+
+In Python 3, the default behaviour of the division operator (see :pep:`238`) has
+been changed but you can have the same behaviour in Python 2 if you import
+``division`` from :mod:`__future__`::
+
+   >>> from __future__ import division
+   >>> print('{:.3f}'.format(1/3))
+   0.333
+
+
+You may also use :ref:`the % operator <string-formatting>` on strings.  See the
+library reference manual for details.

bpo-31506: Clarify error messages for object.__new__ and object.__init__ (GH-11641)

`object.__new__` and `object.__init__` do take one argument each,
they just don't take extra user supplied arguments.

Patch by Sanyam Khurana.

bpo-31506: Clarify error messages for object.__new__ and object.__init__ (GH-11641)


`object.__new__` and `object.__init__` do take one argument each,
they just don't take extra user supplied arguments.

Patch by Sanyam Khurana.
(cherry picked from commit 5105483acb3aca318304bed056dcfd7e188fe4b5)

Re-init _Py_UnhandledKeyboardInterrupt before run. (GH-11963)

Explicitly reinitialize this every eval *just in case* someone is
calling into an embedded Python where they don't care about an uncaught
KeyboardInterrupt exception (why didn't they leave
`config.install_signal_handlers` set to `0`?!?) but then later call
`Py_Main()` itself (which *checks* this flag and dies with a signal after
its interpreter exits).  We don't want a previous embedded interpreter's
uncaught exception to trigger an unexplained signal exit from a future
`Py_Main()` based one.

+Ordered dictionaries are just like regular dictionaries but have some extra

+to remember insertion order (this new behavior became guaranteed in
+Python 3.7).
+
+Some differences from :class:`dict` still remain:
+
+* The regular :class:`dict` was designed to be very good at mapping
+  operations.  Tracking insertion order was secondary.
+
+* The :class:`OrderedDict` was designed to be good at reordering operations.
+  Space efficiency, iteration speed, and the performance of update
+  operations were secondary.
+
+* Algorithmically, :class:`OrderedDict` can handle frequent reordering
+  operations better than :class:`dict`.  This makes it suitable for tracking
+  recent accesses (for example in an `LRU cache
+  <https://medium.com/@krishankantsinghal/my-first-blog-on-medium-583159139237>`_).
+
+* The equality operation for :class:`OrderedDict` checks for matching order.
+
+* The :meth:`popitem` method of :class:`OrderedDict` has a different
+  signature.  It accepts an optional argument to specify which item is popped.
+
+* :class:`OrderedDict` has a :meth:`move_to_end` method to
+  efficiently reposition an element to an endpoint.
+
+* Until Python 3.8, :class:`dict` lacked a :meth:`__reversed__` method.

-the items are returned in the order their keys were first added.
+Ordered dictionaries are just like regular dictionaries but have some extra
+capabilities relating to ordering operations.  They have become less
+important now that the built-in :class:`dict` class gained the ability
+to remember insertion order (this new behavior became guaranteed in
+Python 3.7).
+
+Some differences from :class:`dict` still remain:
+
+* The regular :class:`dict` was designed to be very good at mapping
+  operations.  Tracking insertion order was secondary.
+
+* The :class:`OrderedDict` was designed to be good at reordering operations.
+  Space efficiency, iteration speed, and the performance of update
+  operations were secondary.
+
+* Algorithmically, :class:`OrderedDict` can handle frequent reordering
+  operations better than :class:`dict`.  This makes it suitable for tracking
+  recent accesses (for example in an `LRU cache
+  <https://medium.com/@krishankantsinghal/my-first-blog-on-medium-583159139237>`_).
+
+* The equality operation for :class:`OrderedDict` checks for matching order.
+
+* The :meth:`popitem` method of :class:`OrderedDict` has a different
+  signature.  It accepts an optional argument to specify which item is popped.
+
+* :class:`OrderedDict` has a :meth:`move_to_end` method to
+  efficiently reposition an element to an endpoint.
+
+* Until Python 3.8, :class:`dict` lacked a :meth:`__reversed__` method.

+  opaque ``PyInterpreterState`` is still available as part of the public
+  API (and stable ABI).  The docs indicate that none of the struct's
+  fields are public, so we hope no one has been using them.  However,
+  if you do rely on one or more of those private fields and have no
+  alternative then please open a BPO issue.  We'll work on helping
+  you adjust (possibly including adding accessor functions to the
+  public API).  (See :issue:`35886`.)

 * Asyncio tasks can now be named, either by passing the ``name`` keyword
   argument to :func:`asyncio.create_task` or
   the :meth:`~asyncio.loop.create_task` event loop method, or by

summary:

bpo-35724: Explicitly require the main interpreter for signal-handling. (GH-11530)

Ensure that the main interpreter is active (in the main thread) for signal-handling operations. This is increasingly relevant as people use subinterpreters more.

+
+:class:`NormalDist` objects
+===========================
+
+A :class:`NormalDist` is a a composite class that treats the mean and standard
+deviation of data measurements as a single entity.  It is a tool for creating
+and manipulating normal distributions of a random variable.
+
+Normal distributions arise from the `Central Limit Theorem
+<https://en.wikipedia.org/wiki/Central_limit_theorem>`_ and have a wide range
+of applications in statistics, including simulations and hypothesis testing.
+
+.. class:: NormalDist(mu=0.0, sigma=1.0)
+
+    Returns a new *NormalDist* object where *mu* represents the `arithmetic
+    mean <https://en.wikipedia.org/wiki/Arithmetic_mean>`_ of data and *sigma*
+    represents the `standard deviation
+    <https://en.wikipedia.org/wiki/Standard_deviation>`_ of the data.
+
+    If *sigma* is negative, raises :exc:`StatisticsError`.
+
+    .. attribute:: mu
+
+        The mean of a normal distribution.
+
+    .. attribute:: sigma
+
+        The standard deviation of a normal distribution.
+
+    .. attribute:: variance
+
+       A read-only property representing the `variance
+       <https://en.wikipedia.org/wiki/Variance>`_ of a normal
+       distribution. Equal to the square of the standard deviation.
+
+    .. classmethod:: NormalDist.from_samples(data)
+
+       Class method that makes a normal distribution instance
+       from sample data.  The *data* can be any :term:`iterable`
+       and should consist of values that can be converted to type
+       :class:`float`.
+
+       If *data* does not contain at least two elements, raises
+       :exc:`StatisticsError` because it takes at least one point to estimate
+       a central value and at least two points to estimate dispersion.
+
+    .. method:: NormalDist.samples(n, seed=None)
+
+       Generates *n* random samples for a given mean and standard deviation.
+       Returns a :class:`list` of :class:`float` values.
+
+       If *seed* is given, creates a new instance of the underlying random
+       number generator.  This is useful for creating reproducible results,
+       even in a multi-threading context.
+
+    .. method:: NormalDist.pdf(x)
+
+       Using a `probability density function (pdf)
+       <https://en.wikipedia.org/wiki/Probability_density_function>`_,
+       compute the relative likelihood that a random sample *X* will be near
+       the given value *x*.  Mathematically, it is the ratio ``P(x <= X <
+       x+dx) / dx``.
+
+       Note the relative likelihood of *x* can be greater than `1.0`.  The
+       probability for a specific point on a continuous distribution is `0.0`,
+       so the :func:`pdf` is used instead.  It gives the probability of a
+       sample occurring in a narrow range around *x* and then dividing that
+       probability by the width of the range (hence the word "density").
+
+    .. method:: NormalDist.cdf(x)
+
+       Using a `cumulative distribution function (cdf)
+       <https://en.wikipedia.org/wiki/Cumulative_distribution_function>`_,
+       compute the probability that a random sample *X* will be less than or
+       equal to *x*.  Mathematically, it is written ``P(X <= x)``.
+
+    Instances of :class:`NormalDist` support addition, subtraction,
+    multiplication and division by a constant.  These operations
+    are used for translation and scaling.  For example:
+
+    .. doctest::
+
+        >>> temperature_february = NormalDist(5, 2.5)             # Celsius
+        >>> temperature_february * (9/5) + 32                     # Fahrenheit
+        NormalDist(mu=41.0, sigma=4.5)
+
+    Dividing a constant by an instance of :class:`NormalDist` is not supported.
+
+    Since normal distributions arise from additive effects of independent
+    variables, it is possible to `add and subtract two normally distributed
+    random variables
+    <https://en.wikipedia.org/wiki/Sum_of_normally_distributed_random_variables>`_
+    represented as instances of :class:`NormalDist`.  For example:
+
+    .. doctest::
+
+        >>> birth_weights = NormalDist.from_samples([2.5, 3.1, 2.1, 2.4, 2.7, 3.5])
+        >>> drug_effects = NormalDist(0.4, 0.15)
+        >>> combined = birth_weights + drug_effects
+        >>> f'mu={combined.mu :.1f}   sigma={combined.sigma :.1f}'
+        'mu=3.1   sigma=0.5'
+
+    .. versionadded:: 3.8
+
+
+:class:`NormalDist` Examples and Recipes
+----------------------------------------
+
+A :class:`NormalDist` readily solves classic probability problems.
+
+For example, given `historical data for SAT exams
+<https://blog.prepscholar.com/sat-standard-deviation>`_ showing that scores
+are normally distributed with a mean of 1060 and standard deviation of 192,
+determine the percentage of students with scores between 1100 and 1200:
+
+.. doctest::
+
+    >>> sat = NormalDist(1060, 195)
+    >>> fraction = sat.cdf(1200) - sat.cdf(1100)
+    >>> f'{fraction * 100 :.1f}% score between 1100 and 1200'
+    '18.2% score between 1100 and 1200'
+
+To estimate the distribution for a model than isn't easy to solve
+analytically, :class:`NormalDist` can generate input samples for a `Monte
+Carlo simulation <https://en.wikipedia.org/wiki/Monte_Carlo_method>`_ of the
+model:
+
+.. doctest::
+
+    >>> n = 100_000
+    >>> X = NormalDist(350, 15).samples(n)
+    >>> Y = NormalDist(47, 17).samples(n)
+    >>> Z = NormalDist(62, 6).samples(n)
+    >>> model_simulation = [x * y / z for x, y, z in zip(X, Y, Z)]
+    >>> NormalDist.from_samples(model_simulation)           # doctest: +SKIP
+    NormalDist(mu=267.6516398754636, sigma=101.357284306067)
+
+Normal distributions commonly arise in machine learning problems.
+
+Wikipedia has a `nice example with a Naive Bayesian Classifier
+<https://en.wikipedia.org/wiki/Naive_Bayes_classifier>`_.  The challenge
+is to guess a person's gender from measurements of normally distributed
+features including height, weight, and foot size.
+
+The `prior probability <https://en.wikipedia.org/wiki/Prior_probability>`_ of
+being male or female is 50%:
+
+.. doctest::
+
+    >>> prior_male = 0.5
+    >>> prior_female = 0.5
+
+We also have a training dataset with measurements for eight people.  These
+measurements are assumed to be normally distributed, so we summarize the data
+with :class:`NormalDist`:
+
+.. doctest::
+
+    >>> height_male = NormalDist.from_samples([6, 5.92, 5.58, 5.92])
+    >>> height_female = NormalDist.from_samples([5, 5.5, 5.42, 5.75])
+    >>> weight_male = NormalDist.from_samples([180, 190, 170, 165])
+    >>> weight_female = NormalDist.from_samples([100, 150, 130, 150])
+    >>> foot_size_male = NormalDist.from_samples([12, 11, 12, 10])
+    >>> foot_size_female = NormalDist.from_samples([6, 8, 7, 9])
+
+We observe a new person whose feature measurements are known but whose gender
+is unknown:
+
+.. doctest::
+
+    >>> ht = 6.0        # height
+    >>> wt = 130        # weight
+    >>> fs = 8          # foot size
+
+The posterior is the product of the prior times each likelihood of a
+feature measurement given the gender:
+
+.. doctest::
+
+   >>> posterior_male = (prior_male * height_male.pdf(ht) *
+   ...                   weight_male.pdf(wt) * foot_size_male.pdf(fs))
+
+   >>> posterior_female = (prior_female * height_female.pdf(ht) *
+   ...                     weight_female.pdf(wt) * foot_size_female.pdf(fs))
+
+The final prediction is awarded to the largest posterior -- this is known as
+the `maximum a posteriori
+<https://en.wikipedia.org/wiki/Maximum_a_posteriori_estimation>`_ or MAP:
+
+.. doctest::
+
+  >>> 'male' if posterior_male > posterior_female else 'female'
+  'female'
+
+

summary:

bpo-35813: Tests and docs for shared_memory (#11816)

* Added tests for shared_memory submodule.

* Added tests for ShareableList.

* Fix bug in allocationn size during creation of empty ShareableList illuminated by existing test run on Linux.

* Initial set of docs for shared_memory module.

* Added docs for ShareableList, added doctree entry for shared_memory submodule, name refactoring for greater clarity.

* Added examples to SharedMemoryManager docs, for ease of documentation switched away from exclusively registered functions to some explicit methods on SharedMemoryManager.

* Wording tweaks to docs.

* Fix test failures on Windows.

* Added tests around SharedMemoryManager.

* Documentation tweaks.

* Fix inappropriate test on Windows.

* Further documentation tweaks.

* Fix bare exception.

* Removed __copyright__.

* Fixed typo in doc, removed comment.

* Updated SharedMemoryManager preliminary tests to reflect change of not supporting all registered functions on SyncManager.

* Added Sphinx doctest run controls.

* CloseHandle should be in a finally block in case MapViewOfFile fails.

* Missed opportunity to use with statement.

* Switch to self.addCleanup to spare long try/finally blocks and save one indentation, change to use decorator to skip test instead.

* Simplify the posixshmem extension module.

Provide shm_open() and shm_unlink() functions.  Move other
functionality into the shared_memory.py module.

* Added to doc around size parameter of SharedMemory.

* Changed PosixSharedMemory.size to use os.fstat.

* Change SharedMemory.buf to a read-only property as well as NamedSharedMemory.size.

* Marked as provisional per PEP411 in docstring.

* Changed SharedMemoryTracker to be private.

* Removed registered Proxy Objects from SharedMemoryManager.

* Removed shareable_wrap().

* Removed shareable_wrap() and dangling references to it.

* For consistency added __reduce__ to key classes.

* Fix for potential race condition on Windows for O_CREX.

* Remove unused imports.

* Update access to kernel32 on Windows per feedback from eryksun.

* Moved kernel32 calls to _winapi.

* Removed ShareableList.copy as redundant.

* Changes to _winapi use from eryksun feedback.

* Adopt simpler SharedMemory API, collapsing PosixSharedMemory and WindowsNamedSharedMemory into one.

* Fix missing docstring on class, add test for ignoring size when attaching.

* Moved SharedMemoryManager to managers module, tweak to fragile test.

* Tweak to exception in OpenFileMapping suggested by eryksun.

* Mark a few dangling bits as private as suggested by Giampaolo.

+:mod:`multiprocessing.shared_memory` ---  Provides shared memory for direct access across processes
+===================================================================================================
+
+.. module:: multiprocessing.shared_memory
+   :synopsis: Provides shared memory for direct access across processes.
+
+**Source code:** :source:`Lib/multiprocessing/shared_memory.py`
+
+.. versionadded:: 3.8
+
+.. index::
+   single: Shared Memory
+   single: POSIX Shared Memory
+   single: Named Shared Memory
+
+--------------
+
+This module provides a class, :class:`SharedMemory`, for the allocation
+and management of shared memory to be accessed by one or more processes
+on a multicore or symmetric multiprocessor (SMP) machine.  To assist with
+the life-cycle management of shared memory especially across distinct
+processes, a :class:`~multiprocessing.managers.BaseManager` subclass,
+:class:`SharedMemoryManager`, is also provided in the
+``multiprocessing.managers`` module.
+
+In this module, shared memory refers to "System V style" shared memory blocks
+(though is not necessarily implemented explicitly as such) and does not refer
+to "distributed shared memory".  This style of shared memory permits distinct
+processes to potentially read and write to a common (or shared) region of
+volatile memory.  Processes are conventionally limited to only have access to
+their own process memory space but shared memory permits the sharing
+of data between processes, avoiding the need to instead send messages between
+processes containing that data.  Sharing data directly via memory can provide
+significant performance benefits compared to sharing data via disk or socket
+or other communications requiring the serialization/deserialization and
+copying of data.
+
+
+.. class:: SharedMemory(name=None, create=False, size=0)
+
+   Creates a new shared memory block or attaches to an existing shared
+   memory block.  Each shared memory block is assigned a unique name.
+   In this way, one process can create a shared memory block with a
+   particular name and a different process can attach to that same shared
+   memory block using that same name.
+
+   As a resource for sharing data across processes, shared memory blocks
+   may outlive the original process that created them.  When one process
+   no longer needs access to a shared memory block that might still be
+   needed by other processes, the :meth:`close()` method should be called.
+   When a shared memory block is no longer needed by any process, the
+   :meth:`unlink()` method should be called to ensure proper cleanup.
+
+   *name* is the unique name for the requested shared memory, specified as
+   a string.  When creating a new shared memory block, if ``None`` (the
+   default) is supplied for the name, a novel name will be generated.
+
+   *create* controls whether a new shared memory block is created (``True``)
+   or an existing shared memory block is attached (``False``).
+
+   *size* specifies the requested number of bytes when creating a new shared
+   memory block.  Because some platforms choose to allocate chunks of memory
+   based upon that platform's memory page size, the exact size of the shared
+   memory block may be larger or equal to the size requested.  When attaching
+   to an existing shared memory block, the ``size`` parameter is ignored.
+
+   .. method:: close()
+
+      Closes access to the shared memory from this instance.  In order to
+      ensure proper cleanup of resources, all instances should call
+      ``close()`` once the instance is no longer needed.  Note that calling
+      ``close()`` does not cause the shared memory block itself to be
+      destroyed.
+
+   .. method:: unlink()
+
+      Requests that the underlying shared memory block be destroyed.  In
+      order to ensure proper cleanup of resources, ``unlink()`` should be
+      called once (and only once) across all processes which have need
+      for the shared memory block.  After requesting its destruction, a
+      shared memory block may or may not be immediately destroyed and
+      this behavior may differ across platforms.  Attempts to access data
+      inside the shared memory block after ``unlink()`` has been called may
+      result in memory access errors.  Note: the last process relinquishing
+      its hold on a shared memory block may call ``unlink()`` and
+      :meth:`close()` in either order.
+
+   .. attribute:: buf
+
+      A memoryview of contents of the shared memory block.
+
+   .. attribute:: name
+
+      Read-only access to the unique name of the shared memory block.
+
+   .. attribute:: size
+
+      Read-only access to size in bytes of the shared memory block.
+
+
+The following example demonstrates low-level use of :class:`SharedMemory`
+instances::
+
+   >>> from multiprocessing import shared_memory
+   >>> shm_a = shared_memory.SharedMemory(create=True, size=10)
+   >>> type(shm_a.buf)
+   <class 'memoryview'>
+   >>> buffer = shm_a.buf
+   >>> len(buffer)
+   10
+   >>> buffer[:4] = bytearray([22, 33, 44, 55])  # Modify multiple at once
+   >>> buffer[4] = 100                           # Modify single byte at a time
+   >>> # Attach to an existing shared memory block
+   >>> shm_b = shared_memory.SharedMemory(shm_a.name)
+   >>> import array
+   >>> array.array('b', shm_b.buf[:5])  # Copy the data into a new array.array
+   array('b', [22, 33, 44, 55, 100])
+   >>> shm_b.buf[:5] = b'howdy'  # Modify via shm_b using bytes
+   >>> bytes(shm_a.buf[:5])      # Access via shm_a
+   b'howdy'
+   >>> shm_b.close()   # Close each SharedMemory instance
+   >>> shm_a.close()
+   >>> shm_a.unlink()  # Call unlink only once to release the shared memory
+
+
+
+The following example demonstrates a practical use of the :class:`SharedMemory`
+class with `NumPy arrays <https://www.numpy.org/>`_, accessing the
+same ``numpy.ndarray`` from two distinct Python shells:
+
+.. doctest::
+   :options: +SKIP
+
+   >>> # In the first Python interactive shell
+   >>> import numpy as np
+   >>> a = np.array([1, 1, 2, 3, 5, 8])  # Start with an existing NumPy array
+   >>> from multiprocessing import shared_memory
+   >>> shm = shared_memory.SharedMemory(create=True, size=a.nbytes)
+   >>> # Now create a NumPy array backed by shared memory
+   >>> b = np.ndarray(a.shape, dtype=a.dtype, buffer=shm.buf)
+   >>> b[:] = a[:]  # Copy the original data into shared memory
+   >>> b
+   array([1, 1, 2, 3, 5, 8])
+   >>> type(b)
+   <class 'numpy.ndarray'>
+   >>> type(a)
+   <class 'numpy.ndarray'>
+   >>> shm.name  # We did not specify a name so one was chosen for us
+   'psm_21467_46075'
+
+   >>> # In either the same shell or a new Python shell on the same machine
+   >>> import numpy as np
+   >>> from multiprocessing import shared_memory
+   >>> # Attach to the existing shared memory block
+   >>> existing_shm = shared_memory.SharedMemory(name='psm_21467_46075')
+   >>> # Note that a.shape is (6,) and a.dtype is np.int64 in this example
+   >>> c = np.ndarray((6,), dtype=np.int64, buffer=existing_shm.buf)
+   >>> c
+   array([1, 1, 2, 3, 5, 8])
+   >>> c[-1] = 888
+   >>> c
+   array([  1,   1,   2,   3,   5, 888])
+
+   >>> # Back in the first Python interactive shell, b reflects this change
+   >>> b
+   array([  1,   1,   2,   3,   5, 888])
+
+   >>> # Clean up from within the second Python shell
+   >>> del c  # Unnecessary; merely emphasizing the array is no longer used
+   >>> existing_shm.close()
+
+   >>> # Clean up from within the first Python shell
+   >>> del b  # Unnecessary; merely emphasizing the array is no longer used
+   >>> shm.close()
+   >>> shm.unlink()  # Free and release the shared memory block at the very end
+
+
+.. class:: SharedMemoryManager([address[, authkey]])
+
+   A subclass of :class:`~multiprocessing.managers.BaseManager` which can be
+   used for the management of shared memory blocks across processes.
+
+   A call to :meth:`~multiprocessing.managers.BaseManager.start` on a
+   :class:`SharedMemoryManager` instance causes a new process to be started.
+   This new process's sole purpose is to manage the life cycle
+   of all shared memory blocks created through it.  To trigger the release
+   of all shared memory blocks managed by that process, call
+   :meth:`~multiprocessing.managers.BaseManager.shutdown()` on the instance.
+   This triggers a :meth:`SharedMemory.unlink()` call on all of the
+   :class:`SharedMemory` objects managed by that process and then
+   stops the process itself.  By creating ``SharedMemory`` instances
+   through a ``SharedMemoryManager``, we avoid the need to manually track
+   and trigger the freeing of shared memory resources.
+
+   This class provides methods for creating and returning :class:`SharedMemory`
+   instances and for creating a list-like object (:class:`ShareableList`)
+   backed by shared memory.
+
+   Refer to :class:`multiprocessing.managers.BaseManager` for a description
+   of the inherited *address* and *authkey* optional input arguments and how
+   they may be used to connect to an existing ``SharedMemoryManager`` service
+   from other processes.
+
+   .. method:: SharedMemory(size)
+
+      Create and return a new :class:`SharedMemory` object with the
+      specified ``size`` in bytes.
+
+   .. method:: ShareableList(sequence)
+
+      Create and return a new :class:`ShareableList` object, initialized
+      by the values from the input ``sequence``.
+
+
+The following example demonstrates the basic mechanisms of a
+:class:`SharedMemoryManager`:
+
+.. doctest::
+   :options: +SKIP
+
+   >>> from multiprocessing import shared_memory
+   >>> smm = shared_memory.SharedMemoryManager()
+   >>> smm.start()  # Start the process that manages the shared memory blocks
+   >>> sl = smm.ShareableList(range(4))
+   >>> sl
+   ShareableList([0, 1, 2, 3], name='psm_6572_7512')
+   >>> raw_shm = smm.SharedMemory(size=128)
+   >>> another_sl = smm.ShareableList('alpha')
+   >>> another_sl
+   ShareableList(['a', 'l', 'p', 'h', 'a'], name='psm_6572_12221')
+   >>> smm.shutdown()  # Calls unlink() on sl, raw_shm, and another_sl
+
+The following example depicts a potentially more convenient pattern for using
+:class:`SharedMemoryManager` objects via the :keyword:`with` statement to
+ensure that all shared memory blocks are released after they are no longer
+needed:
+
+.. doctest::
+   :options: +SKIP
+
+   >>> with shared_memory.SharedMemoryManager() as smm:
+   ...     sl = smm.ShareableList(range(2000))
+   ...     # Divide the work among two processes, storing partial results in sl
+   ...     p1 = Process(target=do_work, args=(sl, 0, 1000))
+   ...     p2 = Process(target=do_work, args=(sl, 1000, 2000))
+   ...     p1.start()
+   ...     p2.start()  # A multiprocessing.Pool might be more efficient
+   ...     p1.join()
+   ...     p2.join()   # Wait for all work to complete in both processes
+   ...     total_result = sum(sl)  # Consolidate the partial results now in sl
+
+When using a :class:`SharedMemoryManager` in a :keyword:`with` statement, the
+shared memory blocks created using that manager are all released when the
+:keyword:`with` statement's code block finishes execution.
+
+
+.. class:: ShareableList(sequence=None, *, name=None)
+
+   Provides a mutable list-like object where all values stored within are
+   stored in a shared memory block.  This constrains storable values to
+   only the ``int``, ``float``, ``bool``, ``str`` (less than 10M bytes each),
+   ``bytes`` (less than 10M bytes each), and ``None`` built-in data types.
+   It also notably differs from the built-in ``list`` type in that these
+   lists can not change their overall length (i.e. no append, insert, etc.)
+   and do not support the dynamic creation of new :class:`ShareableList`
+   instances via slicing.
+
+   *sequence* is used in populating a new ``ShareableList`` full of values.
+   Set to ``None`` to instead attach to an already existing
+   ``ShareableList`` by its unique shared memory name.
+
+   *name* is the unique name for the requested shared memory, as described
+   in the definition for :class:`SharedMemory`.  When attaching to an
+   existing ``ShareableList``, specify its shared memory block's unique
+   name while leaving ``sequence`` set to ``None``.
+
+   .. method:: count(value)
+
+      Returns the number of occurrences of ``value``.
+
+   .. method:: index(value)
+
+      Returns first index position of ``value``.  Raises :exc:`ValueError` if
+      ``value`` is not present.
+
+   .. attribute:: format
+
+      Read-only attribute containing the :mod:`struct` packing format used by
+      all currently stored values.
+
+   .. attribute:: shm
+
+      The :class:`SharedMemory` instance where the values are stored.
+
+
+The following example demonstrates basic use of a :class:`ShareableList`
+instance:
+
+   >>> from multiprocessing import shared_memory
+   >>> a = shared_memory.ShareableList(['howdy', b'HoWdY', -273.154, 100, None, True, 42])
+   >>> [ type(entry) for entry in a ]
+   [<class 'str'>, <class 'bytes'>, <class 'float'>, <class 'int'>, <class 'NoneType'>, <class 'bool'>, <class 'int'>]
+   >>> a[2]
+   -273.154
+   >>> a[2] = -78.5
+   >>> a[2]
+   -78.5
+   >>> a[2] = 'dry ice'  # Changing data types is supported as well
+   >>> a[2]
+   'dry ice'
+   >>> a[2] = 'larger than previously allocated storage space'
+   Traceback (most recent call last):
+     ...
+   ValueError: exceeds available storage for existing str
+   >>> a[2]
+   'dry ice'
+   >>> len(a)
+   7
+   >>> a.index(42)
+   6
+   >>> a.count(b'howdy')
+   0
+   >>> a.count(b'HoWdY')
+   1
+   >>> a.shm.close()
+   >>> a.shm.unlink()
+   >>> del a  # Use of a ShareableList after call to unlink() is unsupported
+
+The following example depicts how one, two, or many processes may access the
+same :class:`ShareableList` by supplying the name of the shared memory block
+behind it:
+
+   >>> b = shared_memory.ShareableList(range(5))         # In a first process
+   >>> c = shared_memory.ShareableList(name=b.shm.name)  # In a second process
+   >>> c
+   ShareableList([0, 1, 2, 3, 4], name='...')
+   >>> c[-1] = -999
+   >>> b[-1]
+   -999
+   >>> b.shm.close()
+   >>> c.shm.close()
+   >>> c.shm.unlink()

summary:

bpo-36018: Add properties for mean and stdev (GH-12022)



Responding to suggestions on the tracker and some off-line suggestions.

Davin suggested that english named accessors instead of greek letters would result in more intelligible user code. Steven suggested that the parameters still need to be *mu* and *theta* which are used elsewhere (and I noted those parameter names are used in linked-to resources). 

Michael suggested proving-out the API by seeing whether it generalized to *Lognormal*.  I did so and found that Lognormal distribution parameters *mu* and *sigma*  do not represent the mean and standard deviation of the lognormal distribution (instead, they are for the underlying regular normal distribution).

Putting these ideas together, we have NormalDist parameterized by *mu* and *sigma* but offering English named properties for accessors.  That gives lets us match other API that access mu and sigma, it matches the external resources on the topic, gives us clear english names in user code. The API extends nicely to LogNormal where the parameters and the summary statistic accessors are not the same.

+We added a new internal _Py_AddPendingCall() that operates relative to the
+provided interpreter.  This allows us to use the existing implementation to
+ask another interpreter to do work that cannot be done in the current
+interpreter, like decref an object the other interpreter owns.  The existing
+Py_AddPendingCall() only operates relative to the main interpreter.

bpo-35746: Fix segfault in ssl's cert parser (GH-11569) (#11867)

Fix a NULL pointer deref in ssl module. The cert parser did not handle CRL
distribution points with empty DP or URI correctly. A malicious or buggy
certificate can result into segfault.

Vulnerability (TALOS-2018-0758) reported by Colin Read and Nicolas
Edet of Cisco.

closes bpo-13497: Fix `broken nice` configure test. (GH-12041)

Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.

Fixing the test will prevent false positives with pedantic compilers like clang.

bpo-36123: Fix test_socket.testWithTimeoutTriggeredSend() race condition (GH-12053)

Use longer timeout for accept() in the server and block on accept in the client.
The client now only sets the timeout once the socket is connected.

bpo-28441: Ensure `.exe` suffix in `sys.executable` on MinGW and Cygwin (GH-4348)

This is needed to even the run the test suite on buildbots for affected platforms; e.g.:

```
./python.exe  ./Tools/scripts/run_tests.py -j 1 -u all -W --slowest --fail-env-changed --timeout=11700 -j2
/home/embray/src/python/test-worker/3.x.test-worker/build/python -u -W default -bb -E -W error::BytesWarning -m test -r -w -j 1 -u all -W --slowest --fail-env-changed --timeout=11700 -j2
Traceback (most recent call last):
  File "./Tools/scripts/run_tests.py", line 56, in <module>
    main(sys.argv[1:])
  File "./Tools/scripts/run_tests.py", line 52, in main
    os.execv(sys.executable, args)
PermissionError: [Errno 13] Permission denied
make: *** [Makefile:1073: buildbottest] Error 1
```

bpo-29571: Fix test_re.test_locale_flag() (GH-12099)

Use locale.getpreferredencoding() rather than locale.getlocale() to
get the locale encoding. With some locales, locale.getlocale()
returns the wrong encoding.

For example, on Fedora 29, locale.getlocale() returns ISO-8859-1
encoding for the "en_IN" locale, whereas
locale.getpreferredencoding() reports the correct encoding: UTF-8.

bpo-36142: Exclude coreconfig.h from Py_LIMITED_API (GH-12111)

The whole coreconfig.h header is now excluded from Py_LIMITED_API.
Move functions definitions into a new internal pycore_coreconfig.h
header.

* Move Include/coreconfig.h to Include/cpython/coreconfig.h
* coreconfig.h header is now excluded from Py_LIMITED_API
* Move functions to pycore_coreconfig.h
