Use _PyArg_CheckPositional() and inlined code instead of
PyArg_UnpackTuple() and _PyArg_UnpackStack() if all parameters
are positional and use the "object" converter.
Fix memory leaks in asyncio ProactorEventLoop on overlapped operation
failures.
Changes:
* Implement the tp_traverse slot in the _overlapped.Overlapped type
to help to break reference cycles and identify referrers in the
garbage collector.
* Always clear overlapped on failure: not only set type to
TYPE_NOT_STARTED, but release also resources.
As in title, expose C `raise` function as `raise_function` in `signal` module. Also drop existing `raise_signal` in `_testcapi` module and replace all usages with new function.

Add Clang Memory Sanitizer build instrumentation to work around
false positives from the socket and time modules as well as skipping
a couple test_faulthandler tests.
Use crypt_r() when available instead of crypt() in the crypt module.
As a nice side effect: This also avoids a memory sanitizer flake as clang msan doesn't know about crypt's internal libc allocated buffer.
* bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path
* Add News entry
* fixup! bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path
* Check for tuple in the __get__ of the new descriptor and don't cache the descriptor itself
* Don't inherit from property. Implement GC methods to handle __doc__
* Add a test for the docstring substitution in descriptors
* Update NEWS entry to reflect time against 3.7 branch
* Simplify implementation with argument clinic, better error messages, only __new__
* Use positional-only parameters for the __new__
* Use PyTuple_GET_SIZE and PyTuple_GET_ITEM to tighter the implementation of tuplegetterdescr_get
* Implement __set__ to make tuplegetter a data descriptor
* Use Py_INCREF now that we inline PyTuple_GetItem
* Apply the valid_index() function, saving one test
* Move Py_None test out of the critical path.
* Fix test_mktime on AIX by adding code to get mktime to behave the
same way as it does on other *nix systems
* Fix test_pthread_getcpuclickid in AIX by adjusting the test case
expectations when running on AIX in 32-bit mode
Patch by Michael Felt.
This test case needs "signed short" bitfields, but the
IBM XLC compiler (on AIX) does not support this.
Skip the code and test when AIX and XLC are used.
Use __xlc__ as identifier to detect the XLC compiler.
Include <pyconfig.h> ealier in Modules/expat/xmltok.c to define
properly _POSIX_C_SOURCE. Python defines _POSIX_C_SOURCE as 200809L,
whereas <features.h> (included indirectly by <string.h>) defines
_POSIX_C_SOURCE as 199506L.
The length check for AF_ALG salg_name and salg_type had a off-by-one
error. The code assumed that both values are not necessarily NULL
terminated. However the Kernel code for alg_bind() ensures that the last
byte of both strings are NULL terminated.

In _localemodule.c and selectmodule.c, remove dead code that would
cause double decrefs if run.
In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases
where a new list is populated and there is no possibility of an error.
In addition, check if the list changed size in the loop in array_array_fromlist().
select() calls are retried on EINTR (per PEP 475). However, if a
timeout was provided and the deadline has passed after running the
signal handlers, rlist, wlist and xlist should be cleared since select(2)
left them unmodified.
* bpo-31572: Get rid of PyObject_HasAttrString() in ctypes.
* Fix error handling for _pack_.
* Don't silence errors when look up in a dict.
* Use _PyObject_LookupAttrId().
* More changes.
* PyInit_time() now returns NULL if an exception is raised.
* Rename PyInit_timezone() to init_timezone(). "PyInit_" prefix is
a special prefix for function initializing a module.
init_timezone() doesn't initialize a module and the function is not
exported.
get_gmtoff() now returns time_t instead of int to fix the following
Visual Studio warning:
Modules\timemodule.c(1183): warning C4244: 'return':
conversion from 'time_t' to 'int', possible loss of data
