* Fix auth_login logic (bpo-27820)
* Also fix a longstanding bug in the SimSMTPChannel.found_terminator() method that causes inability to test
SMTP AUTH with initial_response_ok=False.
Check to make sure stdout and stderr are not empty before selecting an item from them in Windows subprocess._communicate.

Add frozen modules to sys.stdlib_module_names. For example, add
"_frozen_importlib" and "_frozen_importlib_external" names.
Add "list_frozen" command to Programs/_testembed.
Added an invalidate_caches() method to the zipimport.zipimporter class based on the implementation of importlib.FileFinder.invalidate_caches(). This was done by adding a get_files() method and an _archive_mtime attribute to zipimport.zipimporter to check for updates or cache invalidation whenever the cache of files and toc entry information in the zipimporter is accessed.
We now buffer the CONNECT request + tunnel HTTP headers into a single
send call. This prevents the OS from generating multiple network
packets for connection setup when not necessary, improving efficiency.
This approach ensures the code matches the interpreter version.
Previously, PYTHON_FOR_REGEN was used to generate the code, which might
be wrong. The marshal format for code objects has changed with
bpo-42246, commit 877df851. Update the code and the expected code sizes
in ctypes test_frozentable.
We can receive signals (at the C level, in `trip_signal()` in signalmodule.c) while `signal.signal` is being called to modify the corresponding handler. Later when `PyErr_CheckSignals()` is called to handle the given signal, the handler may be a non-callable object and would raise a cryptic asynchronous exception.
This is friendlier to other in-process code that an extension module or
embedding use could pull in such as CGo where tiny stacks are the norm
and sigaltstack() has been used to provide for signal handlers.
Without this, signals received by a process using tiny stacks may lead
to stack overflow crashes.
* Unify behavior in ResourceReaderDefaultsTests and align with the behavior found in importlib_resources.
* Equip NamespaceLoader with a NamespaceReader.
* Apply changes from importlib_resources 5.0.4
The following changes are required:
* add a new platform win-arm64
* replace the emulated compiler executable paths
* bump the linker base addressed as ARM64 requires more memory
this change might not be needed (investigation required)
On Windows 10 ARM64, VS compiler paths look like this:
C:\Program Files (x86)\Microsoft Visual
Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\HostX86\ARM64\cl.exe
Note that the cl.exe for ARM64 is an x32 binary, which can run emulated
on Windows 10 ARM64 (it has builtin emulation for x32).
The rc.exe and mc.exe paths have to also be changed, as the initial
discovery has to be fixed.
Work in progress to remove the hardcoded bits and to change the path
query fixes to the proper location.

The case of tempfile.tempdir variable being bytes is now handled consistently.
The getters return the right type and no more error of mixing str and bytes unless explicitly caused by the user.
Adds a regression test.
Expands the documentation to clarify the behavior.

Previously, `datetime.strptime` would match `'z'` with the format string `'%z'` (for UTC offsets), throwing an `IndexError` by erroneously trying to parse `'z'` as a timestamp. As a special case, `'%z'` matches the string `'Z'` which is equivalent to the offset `'+00:00'`, however this behavior is not defined for lowercase `'z'`.
This change ensures a `ValueError` is thrown when encountering the original example, as follows:
```
>>> from datetime import datetime
>>> datetime.strptime('z', '%z')
ValueError: time data 'z' does not match format '%z'
```

Implement an enhanced variant of Crochemore and Perrin's Two-Way string searching algorithm, which reduces worst-case time from quadratic (the product of the string and pattern lengths) to linear. This applies to forward searches (like``find``, ``index``, ``replace``); the algorithm for reverse searches (like ``rfind``) is not changed.

Exit code is now 1 instead of 0. A message is printed to stderr instead of stdout. This is
the proper behaviour for a tool that can be used in scripts.
Printing to IDLE's Shell is often slower than printing to a system
terminal, but it can be made faster by pre-formatting a single
string before printing.
When very large data remains in TextIOWrapper, flush() may fail forever.
So prevent that data larger than chunk_size is remained in TextIOWrapper internal
buffer.

For some mysterious reason we have PySet_Check, PyFrozenSet_Check, PyAnySet_Check, PyAnySet_CheckExact and PyFrozenSet_CheckExact but no PySet_CheckExact.
The types.FunctionType constructor now inherits the current builtins
if the globals dictionary has no "__builtins__" key, rather than
using {"None": None} as builtins: same behavior as eval() and exec()
functions.
Defining a function with "def function(...): ..." in Python is not
affected, globals cannot be overriden with this syntax: it also
inherits the current builtins.
PyFrame_New(), PyEval_EvalCode(), PyEval_EvalCodeEx(),
PyFunction_New() and PyFunction_NewWithQualName() now inherits the
current builtins namespace if the globals dictionary has no
"__builtins__" key.
* Add _PyEval_GetBuiltins() function.
* _PyEval_BuiltinsFromGlobals() now uses _PyEval_GetBuiltins() if
builtins cannot be found in globals.
* Add tstate parameter to _PyEval_BuiltinsFromGlobals().
