The argument order of `link_to()` is reversed compared to what one may expect, so:
a.link_to(b)
Might be expected to create *a* as a link to *b*, in fact it creates *b* as a link to *a*, making it function more like a "link from". This doesn't match `symlink_to()` nor the documentation and doesn't seem to be the original author's intent.
This PR deprecates `link_to()` and introduces `hardlink_to()`, which has the same argument order as `symlink_to()`.
To improve the user experience understanding what part of the error messages associated with SyntaxErrors is wrong, we can highlight the whole error range and not only place the caret at the first character. In this way:
>>> foo(x, z for z in range(10), t, w)
File "<stdin>", line 1
foo(x, z for z in range(10), t, w)
^
SyntaxError: Generator expression must be parenthesized
becomes
>>> foo(x, z for z in range(10), t, w)
File "<stdin>", line 1
foo(x, z for z in range(10), t, w)
^^^^^^^^^^^^^^^^^^^^
SyntaxError: Generator expression must be parenthesized
The inclusion of PyOS_ReadlineFunctionPointer in python3dll.c was a mistake.
According to PEP 384:

- `_Py_EncodeLocaleRaw`, which is private by name, undocumented,
and wasn't exported in `python3.dll`, is moved to a private header.
- `_Py_HashSecret_Initialized`, again private by name, undocumented,
and not exported in `python3.dll`, is excluded with `Py_LIMITED_API`.
- `PyMarshal_*` and `PyMember_*One` functions, declared in private headers and
not exported in `python3.dll`, are removed from `Doc/data/stable_abi.dat`.
- `PyMem_Calloc` which *was* exported in `python3dll.c`, is moved to public
headers where it joins its other `PyMem_*` friends.
Only the last change is documented in the blurb; others are not user-visible.
(Nothing uses `Doc/data/stable_abi.dat` yet.)

This change:
* merges `distutils.sysconfig` into `sysconfig` while keeping the original functionality and
* marks `distutils.sysconfig` as deprecated
https://bugs.python.org/issue41282
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.
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.
