bpo-45383: Get metaclass from bases in PyType_From* (GH-28748)
This checks the bases of of a type created using the FromSpec
API to inherit the bases metaclasses.  The metaclass's alloc
function will be called as is done in `tp_new` for classes
created in Python.

bpo-40514: Drop EXPERIMENTAL_ISOLATED_SUBINTERPRETERS (gh-93185)
This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing:

* the configure option
* the macro
* the code enabled by the macro

gh-60074: add new stable API function PyType_FromMetaclass (GH-93012)
Added a new stable API function ``PyType_FromMetaclass``, which mirrors
the behavior of ``PyType_FromModuleAndSpec`` except that it takes an
additional metaclass argument. This is, e.g., useful for language
binding tools that need to store additional information in the type
object.

gh-93202: Always use %zd printf formatter (#93201)
Python now always use the ``%zu`` and ``%zd`` printf formats to
format a size_t or Py_ssize_t number. Building Python 3.12 requires a
C11 compiler, so these printf formats are now always supported.

* PyObject_Print() and _PyObject_Dump() now use the printf %zd format
  to display an object reference count.
* Update PY_FORMAT_SIZE_T comment.
* Remove outdated notes about the %zd format in PyBytes_FromFormat()
  and PyUnicode_FromFormat() documentations.
* configure no longer checks for the %zd format and no longer defines
  PY_FORMAT_SIZE_T macro in pyconfig.h.
* pymacconfig.h no longer undefines PY_FORMAT_SIZE_T: macOS 10.4 is
  no longer supported. Python 3.12 now requires macOS 10.6 (Snow
  Leopard) or newer.

regular C API and for the limited C API version 3.11 and older to
prevent introducing new compiler warnings.

Check result of utc_to_seconds and skip fold probe in pure Python (#91582)
The `utc_to_seconds` call can fail, here's a minimal reproducer on
Linux:

TZ=UTC python -c "from datetime import *; datetime.fromtimestamp(253402300799 + 1)"

The old behavior still raised an error in a similar way, but only
because subsequent calculations happened to fail as well. Better to fail
fast.

This also refactors the tests to split out the `fromtimestamp` and
`utcfromtimestamp` tests, and to get us closer to the actual desired
limits of the functions. As part of this, we also changed the way we
detect platforms where the same limits don't necessarily apply (e.g.
Windows).

As part of refactoring the tests to hit this condition explicitly (even
though the user-facing behvior doesn't change in any way we plan to
guarantee), I noticed that there was a difference in the places that
`datetime.utcfromtimestamp` fails in the C and pure Python versions, which
was fixed by skipping the "probe for fold" logic for UTC specifically —
since UTC doesn't have any folds or gaps, we were never going to find a
fold value anyway. This should prevent some failures in the pure python
`utcfromtimestamp` method on timestamps close to 0001-01-01.

There are two separate news entries for this because one is a
potentially user-facing change, the other is an internal code
correctness change that, if anything, changes some error messages. The
two happen to be coupled because of the test refactoring, but they are
probably best thought of as independent changes.

Fixes GH-91581

Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related.

gh-92345: Import rlcompleter before sys.path is extended (#92346)
``pymain_run_python()`` now imports ``readline`` and ``rlcompleter``
before sys.path is extended to include the current working directory of
an interactive interpreter. Non-interactive interpreters are not
affected.

Also move imports of ``re`` and ``keyword`` module to top level so they
are materialized early, too. The ``keyword`` module is trivial and the
``re`` is already imported via ``inspect`` -> ``linecache``.

gh-92301: subprocess: Prefer close_range() to procfs-based fd closing (#92303)
#92301: subprocess: Prefer `close_range()` to procfs-based fd closing.

`close_range()` is much faster for large number of file descriptors, e.g.
4 times faster for 1000 descriptors in a Linux 5.16-based environment.

We prefer close_range() only if it's known to be async-signal-safe.

gh-89022: Improve sqlite3 exceptions related to binding params and API misuse (#91572)
* Map SQLITE_MISUSE to sqlite3.InterfaceError

SQLITE_MISUSE implies misuse of the SQLite C API, which, if it happens,
is _not_ a user error; it is an sqlite3 extension module error.

* Raise better errors when binding parameters fail.

Instead of always raising InterfaceError, guessing what went wrong,
raise accurate exceptions with more accurate error messages.

Use static inline function Py_EnterRecursiveCall() (#91988)
Currently, calling Py_EnterRecursiveCall() and

function call, depending if the internal pycore_ceval.h header file

function to ensure that the static inline function is always used in
Python internals for best performance. Similar approach than
PyThreadState_GET() (function call) and _PyThreadState_GET() (static
inline function).
