Change behavior of ``sys.monitoring.events.LINE`` events in

``sys.monitoring``: Line events now occur when a new line is reached

dynamically, instead of using a static approximation, as before. This makes

the behavior very similar to that of "line" events in ``sys.settrace``. This

should ease porting of tools from 3.11 to 3.12.

meaning. Also introduce a new macro ``Py_INFINITY`` matching C99's

``INFINITY`` macros instead of hard-coding bit patterns for infinities and

NaNs. Thanks Sebastian Berg.

Multi-phase init extension modules may now indicate that they support
|
|
running in subinterpreters that have their own GIL. This is done by using
|
|
``Py_MOD_PER_INTERPRETER_GIL_SUPPORTED`` as the value for the
|
|
``Py_mod_multiple_interpreters`` module def slot. Otherwise the module, by
|
|
default, cannot be imported in such subinterpreters. (This does not affect
|
|
the main interpreter or subinterpreters that do not have their own GIL.) In
|
|
addition to the isolation that multi-phase init already normally requires,
|
|
support for per-interpreter GIL involves one additional constraint:
|
|
thread-safety. If the module has external (linked) dependencies and those
|
|
libraries have any state that isn't thread-safe then the module must do the
|
|
additional work to add thread-safety. This should be an uncommon case.

The GIL is now (optionally) per-interpreter. This is the fundamental change
|
|
for PEP 684. This is all made possible by virtue of the isolated state of
|
|
each interpreter in the process. The behavior of the main interpreter
|
|
remains unchanged. Likewise, interpreters created using
|
|
``Py_NewInterpreter()`` are not affected. To get an interpreter with its
|
|
own GIL, call ``Py_NewInterpreterFromConfig()``.

Multi-phase init extension modules may now indicate whether or not they
|
|
actually support multiple interpreters. By default such modules are
|
|
expected to support use in multiple interpreters. In the uncommon case that
|
|
one does not, it may use the new ``Py_mod_multiple_interpreters`` module def
|
|
slot. A value of ``0`` means the module does not support them. ``1`` means
|
|
it does. The default is ``1``.

Implement :pep:`695`, adding syntactic support for generic classes, generic
|
|
functions, and type aliases.
|
|
|
|
A new ``type X = ...`` syntax is added for type aliases, which resolves at
|
|
runtime to an instance of the new class ``typing.TypeAliasType``. The value
|
|
is lazily evaluated and is accessible through the ``.__value__`` attribute.
|
|
This is implemented as a new AST node ``ast.TypeAlias``.
|
|
|
|
New syntax (``class X[T]: ...``, ``def func[T](): ...``) is added for
|
|
defining generic functions and classes. This is implemented as a new
|
|
``type_params`` attribute on the AST nodes for classes and functions. This
|
|
node holds instances of the new AST classes ``ast.TypeVar``,
|
|
``ast.ParamSpec``, and ``ast.TypeVarTuple``.
|
|
|
|
``typing.TypeVar``, ``typing.ParamSpec``, ``typing.ParamSpecArgs``,
|
|
``typing.ParamSpecKwargs``, ``typing.TypeVarTuple``, and ``typing.Generic``
|
|
are now implemented in C rather than Python.
|
|
|
|
There are new bytecode instructions ``LOAD_LOCALS``,
|
|
``LOAD_CLASSDICT_OR_GLOBAL``, and ``LOAD_CLASSDICT_OR_DEREF`` to support
|
|
correct resolution of names in class namespaces.

Updated ``importlib.metadata`` with changes from ``importlib_metadata`` 5.2

|
through 6.5.0, including: Support ``installed-files.txt`` for
|
|
``Distribution.files`` when present. ``PackageMetadata`` now stipulates an
|
|
additional ``get`` method allowing for easy querying of metadata keys that
|
|
may not be present. ``packages_distributions`` now honors packages and
|
|
modules with Python modules that not ``.py`` sources (e.g. ``.pyc``,
|
|
``.so``). Expand protocol for ``PackageMetadata.get_all`` to match the
|
|
upstream implementation of ``email.message.Message.get_all`` in
|
|
python/typeshed#9620. Deprecated use of ``Distribution`` without defining
|
|
abstract methods. Deprecated expectation that
|
|
``PackageMetadata.__getitem__`` will return ``None`` for missing keys. In
|
|
the future, it will raise a ``KeyError``.

Implemented an eager task factory in asyncio. When used as a task factory on
|
|
an event loop, it performs eager execution of coroutines. Coroutines that
|
|
are able to complete synchronously (e.g. return or raise without blocking)
|
|
are returned immediately as a finished task, and the task is never scheduled
|
|
to the event loop. If the coroutine blocks, the (pending) task is scheduled
|
|
and returned.

We've added ``Py_NewInterpreterFromConfig()`` and ``PyInterpreterConfig`` to
|
|
the public C-API (but not the stable ABI; not yet at least). The new
|
|
function may be used to create a new interpreter with various features
|
|
configured. The function was added to support PEP 684 (per-interpreter
|
|
GIL).

:c:func:`PyType_FromSpec` and its variants now allow creating classes whose

metaclass overrides :c:member:`~PyTypeObject.tp_new`. The ``tp_new`` is

ignored. This behavior is deprecated and will be disallowed in 3.14+. The
|
|
new :c:func:`PyType_FromMetaclass` already disallows it.

Introduced :c:func:`PyUnstable_WritePerfMapEntry`,
|
|
:c:func:`PyUnstable_PerfMapState_Init` and
|
|
:c:func:`PyUnstable_PerfMapState_Fini`. These allow extension modules (JIT
|
|
compilers in particular) to write to perf-map files in a thread safe manner.
|
|
The :doc:`../howto/perf_profiling` also uses these APIs to write entries in
|
|
the perf-map file.

:c:member:`PyType_Spec.basicsize` can now be zero or negative,

:c:func:`PyObject_GetTypeData` can be used to get subclass-specific data,

and :c:macro:`Py_TPFLAGS_ITEMS_AT_END` can be used to safely extend
|
|
variable-size objects. See :pep:`697` for details.
