Frozen modules must be added to several files in order to work properly. Before this change this had to be done manually. Here we add a tool to generate the relevant lines in those files instead. This helps us avoid mistakes and omissions.
https://bugs.python.org/issue45019
* Functions registered with addModuleCleanup() were not called unless
the user defines tearDownModule() in their test module.
* Functions registered with addClassCleanup() were not called if
tearDownClass is set to None.
* Buffering in TestResult did not work with functions registered
with addClassCleanup() and addModuleCleanup().
* Errors in functions registered with addClassCleanup() and
addModuleCleanup() were not handled correctly in buffered and
debug modes.
* Errors in setUpModule() and functions registered with
addModuleCleanup() were reported in wrong order.
* And several lesser bugs.
Previously it returned None if the test class or method was
decorated with a skipping decorator.

Previously, when built on older macOS systems, `find_library` was not able to find macOS system libraries when running on Big Sur due to changes in how system libraries are stored.
Update the vendored copy of libexpat to 2.4.1 (from 2.2.8) to get the
fix for the CVE-2013-0340 "Billion Laughs" vulnerability. This copy
is most used on Windows and macOS.

Various date parsing utilities in the email module, such as
email.utils.parsedate(), are supposed to gracefully handle invalid
input, typically by raising an appropriate exception or by returning
None.
The internal email._parseaddr._parsedate_tz() helper used by some of
these date parsing routines tries to be robust against malformed input,
but unfortunately it can still crash ungracefully when a non-empty but
whitespace-only input is passed. This manifests as an unexpected
IndexError.
In practice, this can happen when parsing an email with only a newline
inside a ‘Date:’ header, which unfortunately happens occasionally in the
real world.
Here's a minimal example:
$ python
Python 3.9.6 (default, Jun 30 2021, 10:22:16)
[GCC 11.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import email.utils
>>> email.utils.parsedate('foo')
>>> email.utils.parsedate(' ')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.9/email/_parseaddr.py", line 176, in parsedate
t = parsedate_tz(data)
File "/usr/lib/python3.9/email/_parseaddr.py", line 50, in parsedate_tz
res = _parsedate_tz(data)
File "/usr/lib/python3.9/email/_parseaddr.py", line 72, in _parsedate_tz
if data[0].endswith(',') or data[0].lower() in _daynames:
IndexError: list index out of range
The fix is rather straight-forward: guard against empty lists, after
splitting on whitespace, but before accessing the first element.
* Fix typo in __repr__ code
* Add more tests for global int flag reprs
* use last module if multi-module string
- when an enum's `__module__` contains several module names, only
use the last one

* Use binascii.a2b_base64 to validate b64decode input.
This change leads to exception messages changes (mostly).
* Added more information to docstring of b64decode
* Added a reference to binascii.a2b_base64 in the docs
* Use "X | Y" instead of "Union" where it makes sense.
* Mention that "X | Y" is equivalent to "Union[X, Y]" in Union section.
* Remove "Optional[X]" as shorthand for "Union[X, None]" as the new
shorthand is now "X | None".
* Mention that "Optional[X]" can be written as "X | None" in section
about "Optional".

Method stopTestRun() is now always called in pair with method startTestRun()
for TestResult objects implicitly created in TestCase.run().
Previously it was not called for test methods and classes decorated with
a skipping decorator.
Implements a two steps check in `importlib._bootstrap._find_and_load()` to avoid locking when the module has been already imported and it's ready.
---
Using `importlib.__import__()`, after this, does show a big difference:
Before:
```
$ ./python -c 'import timeit; print(timeit.timeit("__import__(\"timeit\")", setup="from importlib import __import__"))'
15.92248619502061
```
After:
```
$ ./python -c 'import timeit; print(timeit.timeit("__import__(\"timeit\")", setup="from importlib import __import__"))'
1.206068897008663
```
---
On non-Linux POSIX platforms, like FreeBSD or macOS,
the FD used to read a forked PTY may signal its exit not
by raising an error but by sending empty data to the read
syscall. This case wasn't handled, leading to hanging
`pty.spawn` calls.

MemoryError raised in user-defined functions will now preserve
its type. OverflowError will now be converted to DataError.
Previously both were converted to OperationalError.
Fix the os.set_inheritable() function on FreeBSD 14 for file
descriptor opened with the O_PATH flag: ignore the EBADF error on
ioctl(), fallback on the fcntl() implementation.
* When trying to allocate very large regions on macOS, malloc does not fail silently. It sends a noisy error out to STDERR
* This provides a helper function to warn the user, and provides the warning for test_decimal, which consistently generates these warnings on macOS.

The threading debug (PYTHONTHREADDEBUG environment variable) is
deprecated in Python 3.10 and will be removed in Python 3.12. This
feature requires a debug build of Python.
* Unify the C and Python implementations of OrderedDict.popitem().
The C implementation no longer calls ``__getitem__`` and ``__delitem__``
methods of the OrderedDict subclasses.
* Change popitem() and pop() methods of collections.OrderedDict
For consistency with dict both implementations (pure Python and C)
of these methods in OrderedDict no longer call __getitem__ and
__delitem__ methods of the OrderedDict subclasses.
Previously only the Python implementation of popitem() did not
call them.
For example Callable[P, T][[int], str, float] will now raise an error.
Use also term "arguments" instead of "parameters" in error
message for too few/many arguments.
When sys.stdout.encoding is None compile_file will fall back to
sys.getdefaultencoding to encode/decode error messages.

* rlcompleter was calling these methods to identify whether to add
parenthesis to the completion, based on if the attribute is callable.
* for property objects, completion with parenthesis are never desirable.
* property methods with print statements behaved very strangely, which
was especially unfriendly to language newcomers. <tab> could suddenly
produce output unexpectedly.
`pathlib.PureWindowsPath.is_reserved()` now identifies as reserved
filenames with trailing spaces or colons.

This fixes TypedDict to work with get_type_hints and postponed evaluation of annotations across modules.
This is done by adding the module name to ForwardRef at the time the object is created and using that to resolve the globals during the evaluation.

Patch by Erik Welch.
bpo-19072 (#8405) allows `classmethod` to wrap other descriptors, but this does
not work when the wrapped descriptor mimics classmethod. The current PR fixes
this.
In Python 3.8 and before, one could create a callable descriptor such that this
works as expected (see Lib/test/test_decorators.py for examples):
```python
class A:
@myclassmethod
def f1(cls):
return cls
@classmethod
@myclassmethod
def f2(cls):
return cls
```
In Python 3.8 and before, `A.f2()` return `A`. Currently in Python 3.9, it
returns `type(A)`. This PR make `A.f2()` return `A` again.
As of #8405, classmethod calls `obj.__get__(type)` if `obj` has `__get__`.
This allows one to chain `@classmethod` and `@property` together. When
using classmethod-like descriptors, it's the second argument to `__get__`--the
owner or the type--that is important, but this argument is currently missing.
Since it is None, the "owner" argument is assumed to be the type of the first
argument, which, in this case, is wrong (we want `A`, not `type(A)`).
This PR updates classmethod to call `obj.__get__(type, type)` if `obj` has
`__get__`.

* Fix issubclass() for None.
E.g. issubclass(type(None), int | None) returns now True.
* Fix issubclass() for virtual subclasses.
E.g. issubclass(dict, int | collections.abc.Mapping) returns now True.
* Fix crash in isinstance() if the check for one of items raises exception.
Heap types with the Py_TPFLAGS_IMMUTABLETYPE flag can now inherit the
PEP 590 vectorcall protocol. Previously, this was only possible for static types.
