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.

TemporaryDirectory.cleanup() failed when non-writeable or non-searchable
files or directories were created inside a temporary directory.

Escape ``\r``, ``\0`` and ``\x1a`` (end-of-file on Windows) in Unicode strings.

It seems to be the only widget label not capitalized.

Automatically replace
tp_print -> tp_vectorcall_offset
tp_compare -> tp_as_async
tp_reserved -> tp_as_async

This is an old feature request that appears from time to time. After a year of experimenting with various introspection capabilities in `typing_inspect` on PyPI, I propose to add these two most commonly used functions: `get_origin()` and `get_args()`. These are essentially thin public wrappers around private APIs: `__origin__` and `__args__`.

As discussed in the issue and on the typing tracker, exposing some public helpers instead of `__origin__` and `__args__` directly will give us more flexibility if we will decide to update the internal representation, while still maintaining backwards compatibility.

The implementation is very simple an is essentially a copy from `typing_inspect` with one exception: `ClassVar` was special-cased in `typing_inspect`, but I think this special-casing doesn't really help and only makes things more complicated.

Bump the removal to 3.9, indicate collections.abc available since 3.3,
replace version-changed directive to deprecated-removed.

As per the PEP and the [audit event raised](https://github.com/python/cpython/blob/13d4e6a4a090031f8214e058ed3c8fd47767e05f/Lib/urllib/request.py#L524) in urllib.request this should be `urllib.Request`

There is no need to clear these immutable objects during shutdown.

From 3.8 async functions used with mock.patch return an `AsyncMock`. `_accept_connection2` is an async function where create_task is also mocked. Don't mock `create_task` so that tasks are created out of coroutine returned by `AsyncMock` and the tasks are completed.

In e895de3e, the
deprecated function PyErr_SetFromWindowsErrWithUnicodeFilename() was
added in two functions in Modules/_winapi.c. This function was
deprecated in 3.3.

bpo-37007: Implement socket.if_nametoindex(), if_indextoname() and if_nameindex() on Windows (GH-13522)

As it changes the way functions are called, the PEP 590 implementation
skipped the functions that the GDB integration is looking for
(by name) to find function calls.

Looking for the new helper `cfunction_call_varargs` hopefully fixes the
tests, and thus buildbots.

The changed frame nuber in test_gdb is due to there being fewer
C calls when calling a built-in method.

It is now allowed to add new fields at the end of the PyTypeObject struct without having to allocate a dedicated compatibility flag in tp_flags.

This will reduce the risk of running out of bits in the 32-bit tp_flags value.

* bpo-22385: Support output separators in hex methods.

Also in binascii.hexlify aka b2a_hex.

The underlying implementation behind all hex generation in CPython uses the
same pystrhex.c implementation.  This adds support to bytes, bytearray,
and memoryview objects.

The binascii module functions exist rather than being slated for deprecation
because they return bytes rather than requiring an intermediate step through a
str object.

This change was inspired by MicroPython which supports sep in its binascii
implementation (and does not yet support the .hex methods).
