The sys module uses the kernel32.dll version number, which can vary from the "actual" Windows version.
Since the best option for getting the version is WMI (which is expensive), we switch back to launching cmd.exe (which is also expensive, but a lot less code on our part).
sys.getwindowsversion() is not updated to avoid launching executables from that module.
Previously TestIntEnumConvert and TestStrEnumConvert would end up
converting the module level variables from their regular int form
to a `test.test_enum.X` instance after _convert would run. This
meant that after a single test ran, the next set of _convert
functions would be operating on the enum instances rather than
ints. This would cause some tests such as the one involving format
to fail when running under a mode that repeatedly runs test such
as the refleak finder.
Add pycore_moduleobject.h internal header file with static inline
functions to access module members:
* _PyModule_GetDict()
* _PyModule_GetDef()
* _PyModule_GetState()
These functions don't check at runtime if their argument has a valid
type and can be inlined even if Python is not built with LTO.
_PyType_GetModuleByDef() uses _PyModule_GetDef().
Replace PyModule_GetState() with _PyModule_GetState() in the
extension modules, considered as performance sensitive:
* _abc
* _functools
* _operator
* _pickle
* _queue
* _random
* _sre
* _struct
* _thread
* _winapi
* array
* posix
The following extensions are now built with the Py_BUILD_CORE_MODULE
macro defined, to be able to use the internal pycore_moduleobject.h
header: _abc, array, _operator, _queue, _sre, _struct.
PyType_Ready() now ensures that a type MRO cannot be empty.
_PyType_GetModuleByDef() no longer checks "i < PyTuple_GET_SIZE(mro)"
at the first loop iteration to optimize the most common case, when
the argument is the defining class.
_PyType_GetModuleByDef() no longer checks if types are heap types.
_PyType_GetModuleByDef() must only be called on a heap type created
by PyType_FromModuleAndSpec() or on its subclasses.
type_ready_mro() ensures that a static type cannot inherit from a
heap type.
add:
* `_simple_enum` decorator to transform a normal class into an enum
* `_test_simple_enum` function to compare
* `_old_convert_` to enable checking `_convert_` generated enums
`_simple_enum` takes a normal class and converts it into an enum:
@simple_enum(Enum)
class Color:
RED = 1
GREEN = 2
BLUE = 3
`_old_convert_` works much like` _convert_` does, using the original logic:
# in a test file
import socket, enum
CheckedAddressFamily = enum._old_convert_(
enum.IntEnum, 'AddressFamily', 'socket',
lambda C: C.isupper() and C.startswith('AF_'),
source=_socket,
)
`_test_simple_enum` takes a traditional enum and a simple enum and
compares the two:
# in the REPL or the same module as Color
class CheckedColor(Enum):
RED = 1
GREEN = 2
BLUE = 3
_test_simple_enum(CheckedColor, Color)
_test_simple_enum(CheckedAddressFamily, socket.AddressFamily)
Any important differences will raise a TypeError

The ssl module now uses ``SSL_read_ex`` and ``SSL_write_ex``
internally. The functions support reading and writing of data larger
than 2 GB. Writing zero-length data no longer fails with a protocol
violation error.

Many servers in the cloud environment require SNI to be used during the
SSL/TLS handshake, therefore it is not possible to fetch their certificates
using the ssl.get_server_certificate interface.
This change adds an additional optional hostname argument that can be used to
set the SNI. Note that it is intentionally a separate argument instead of
using the host part of the addr tuple, because one might want to explicitly
fetch the default certificate or fetch a certificate from a specific IP
address with the specified SNI hostname. A separate argument also works better
for backwards compatibility.

Commit 93d50a6a8d / GH-21855 changed the
order of variable definitions, which introduced a potential invalid free
bug. Py_buffer object is now initialized earlier and the result of
Keccak initialize is verified.

Since we can use now the sha3 and shake algorithms from OpenSSL, we shouldn't
skip the tests in case the builtin algorithm was not compiled or removed.
- Introduce sslmodule_slots
- Introduce sslmodulestate

Use a versionadded directive to generate the text "New in version
3.8." (to match with the documentation of other modules).

The multiprocessing Server class now explicitly catchs SystemExit and
closes the client connection in this case. It happens when the
Server.serve_client() method reachs the end of file (EOF).
