The PyObject_INIT() and PyObject_INIT_VAR() macros become aliases to,
respectively, PyObject_Init() and PyObject_InitVar() functions.
Rename _PyObject_INIT() and _PyObject_INIT_VAR() static inline
functions to, respectively, _PyObject_Init() and _PyObject_InitVar(),
and move them to pycore_object.h. Remove their return value:
their return type becomes void.
The _datetime module is now built with the Py_BUILD_CORE_MODULE macro
defined.
Remove an outdated comment on _Py_tracemalloc_config.
This commit removes the old parser, the deprecated parser module, the old parser compatibility flags and environment variables and all associated support code and documentation.
This reverts commit 0da5466650.
The commit is causing make failures on a FreeBSD buildbot.
Due to the imminent 3.9.0b1 cutoff, revert this commit for
now pending further investigation.
Add support to the configure script for OBJC and OBJCXX command line options so that the macOS builds can use the clang compiler for the macOS-specific Objective C source files. This allows third-party compilers, like GNU gcc, to be used to build the rest of the project since some of the Objective C system header files are not compilable by GNU gcc.

_tkinter now builds and links with non-system Tcl and Tk frameworks if they
are installed in /Library/Frameworks as had been the case on older releases
of macOS. If a macOS SDK is explicitly configured, by using ./configure
--enable-universalsdk= or -isysroot, only a Library/Frameworks directory in
the SDK itself is searched. The default behavior can still be overridden with
configure --with-tcltk-includes and --with-tcltk-libs.
When an asyncio.Task is cancelled, the exception traceback now
starts with where the task was first interrupted. Previously,
the traceback only had "depth one."
This is the initial implementation of PEP 615, the zoneinfo module,
ported from the standalone reference implementation (see
https://www.python.org/dev/peps/pep-0615/#reference-implementation for a
link, which has a more detailed commit history).
This includes (hopefully) all functional elements described in the PEP,
but documentation is found in a separate PR. This includes:
1. A pure python implementation of the ZoneInfo class
2. A C accelerated implementation of the ZoneInfo class
3. Tests with 100% branch coverage for the Python code (though C code
coverage is less than 100%).
4. A compile-time configuration option on Linux (though not on Windows)
Differences from the reference implementation:
- The module is arranged slightly differently: the accelerated module is
`_zoneinfo` rather than `zoneinfo._czoneinfo`, which also necessitates
some changes in the test support function. (Suggested by Victor
Stinner and Steve Dower.)
- The tests are arranged slightly differently and do not include the
property tests. The tests live at test/test_zoneinfo/test_zoneinfo.py
rather than test/test_zoneinfo.py or test/test_zoneinfo/__init__.py
because we may do some refactoring in the future that would likely
require this separation anyway; we may:
- include the property tests
- automatically run all the tests against both pure Python and C,
rather than manually constructing C and Python test classes (similar
to the way this works with test_datetime.py, which generates C
and Python test cases from datetimetester.py).
- This includes a compile-time configuration option on Linux (though not
on Windows); added with much help from Thomas Wouters.
- Integration into the CPython build system is obviously different from
building a standalone zoneinfo module wheel.
- This includes configuration to install the tzdata package as part of
CI, though only on the coverage jobs. Introducing a PyPI dependency as
part of the CI build was controversial, and this is seen as less of a
major change, since the coverage jobs already depend on pip and PyPI.
Additional changes that were introduced as part of this PR, most / all of
which were backported to the reference implementation:
- Fixed reference and memory leaks
With much debugging help from Pablo Galindo
- Added smoke tests ensuring that the C and Python modules are built
The import machinery can be somewhat fragile, and the "seamlessly falls
back to pure Python" nature of this module makes it so that a problem
building the C extension or a failure to import the pure Python version
might easily go unnoticed.
- Adjustments to zoneinfo.__dir__
Suggested by Petr Viktorin.
- Slight refactorings as suggested by Steve Dower.
- Removed unnecessary if check on std_abbr
Discovered this because of a missing line in branch coverage.
It is possible to use either '-isysroot /some/path' (with a space) or
'-isysroot/some/path' (no space in between). Support both forms in
places where special handling of -isysroot is done, rather than just
the first form.

Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.
Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().
Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.
The _random module is now built with Py_BUILD_CORE_MODULE defined.
Add a new internal pycore_byteswap.h header file with the following
functions:
* _Py_bswap16()
* _Py_bswap32()
* _Py_bswap64()
Use these functions in _ctypes, sha256 and sha512 modules,
and also use in the UTF-32 encoder.
sha256, sha512 and _ctypes modules are now built with the internal
C API.
Add os.waitstatus_to_exitcode() function to convert a wait status to an
exitcode.
Suggest waitstatus_to_exitcode() usage in the documentation when
appropriate.
Use waitstatus_to_exitcode() in:
* multiprocessing, os, subprocess and _bootsubprocess modules;
* test.support.wait_process();
* setup.py: run_command();
* and many tests.
Add _bootsubprocess module to bootstrap Python: subprocess
implementation which only uses the os module.
On AIX, distutils.util uses _aix_support which calls
subprocess.check_output(), before the _posixsubprocess module is
built. Implement check_output() with os.system() in _bootsubprocess.
Reimplement distutils.spawn.spawn() function with the subprocess
module.
setup.py now uses a basic implementation of the subprocess module if
the subprocess module is not available: before required C extension
modules are built.
Move the dtoa.h header file to the internal C API as pycore_dtoa.h:
it only contains private functions (prefixed by "_Py").
The math and cmath modules must now be compiled with the
Py_BUILD_CORE macro defined.
* Switch to officially supported curses from 3rd-party ASIS supported ncurses
* stop saying optional modules osaudiodev and spwd are missing on AIX
Patch by M.Felt
The ssl module now can dump key material to a keylog file and trace TLS
protocol messages with a tracing callback. The default and stdlib
contexts also support SSLKEYLOGFILE env var.
The msg_callback and related enums are private members. The feature
is designed for internal debugging and not for end users.

Add a new _testinternalcapi module to test the internal C API.
Move _Py_GetConfigsAsDict() function to the internal C API:
_testembed now uses _testinternalcapi to access the function.
Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros
of pyport.h when Py_BUILD_CORE_MODULE is defined.
The Py_BUILD_CORE_MODULE define must be now be used to build a C
extension as a dynamic library accessing Python internals: export the
PyInit_xxx() function in DLL exports on Windows.
Changes:
* Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply
Py_BUILD_CORE directy in pyport.h.
* ceval.c compilation now fails with an error if Py_BUILD_CORE is not
defined, just to ensure that Python is build with the correct
defines.
* setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define.
* setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather
than Py_BUILD_CORE_BUILTIN define
* PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.
[bpo-36146](https://bugs.python.org/issue36146) introduced another regression. In case of missing OpenSSL
libraries or headers, setup.py no longer reported _hashlib and _ssl to
be missing.

Add TEST_EXTENSIONS constant to setup.py to allow to not build test
extensions like _testcapi.
Changes:
* Add add_ldflags_cppflags() subfunction
* Rename add_compiler_directories() to configure_compiler().
* Remove unused COMPILED_WITH_PYDEBUG constant.
* Use self.add() rather than accessing directly self.extensions.
* Remove module_enabled() function: check differently if curses
extension is built or not.
* Move set_compiler_flags() calls and concurrent.future hack from
module top-level to main()
* Remove unused variables 'macros' and 'libraries' from
detect_multiprocessing().
* Move SUMMARY and CLASSIFIERS constants at the top, move
set_compiler_flags() function below these constants.
* Add some empty new lines to respect PEP 8.
* Split PyBuildExt.detect_modules() huge function into subfunctions.
* Move curses, hashlib and some other code to reorganize the code.
* detect_tkinter() now returns False if the extension is missing.
* Add PyBuildExt.config_h_vars attribute
* Add PyBuildExt.srcdir atribute in setup.py: the source directory is
now always absolute.
* Add PyBuildExt.inc_dirs and PyBuildExt.lib_dirs attributes:
replace 'inc_dirs' and 'lib_dirs' local variables of
detect_modules().
* Replace "from distutils.errors import *"
with "from distutils.errors import CCompilerError, DistutilsError"
to be able to use static analyzers like pyflakes
* Reorder imports.
* Add PyBuildExt.add() which adds the extension directly to
self.extensions, rather than using a temporary 'exts' local
variable in detect_modules() and then add 'exts' to self.extensions
* Convert 'missing' local variable from detect_modules()
into PyBuildExt.missing attribute
* _detect_openssl(), _decimal_ext() and _detect_nis() now call
directly self.add(), rather than returning an extension
(or None if not found).
* Rename _decimal_ext() to _detect_decimal() for consistency with
other methods.
* Rename globals to upper case to better distinguish if a variable is
global or local:
* Rename cross_compiling to CROSS_COMPILING
* Rename host_platform to HOST_PLATFORM
* Rename disabled_module_list to DISABLED_MODULE_LIST
* Add MS_WINDOWS, CYGWIN and MACOS constants.
* Use booleans: replace "return 0" with "return False"
and replace "return 1" with "return True"
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.
