The IDNA codec decoder used on DNS hostnames by :mod:`socket` or
|
|
:mod:`asyncio` related name resolution functions no longer involves a
|
|
quadratic algorithm. This prevents a potential CPU denial of service if an
|
|
out-of-spec excessive length hostname involving bidirectional characters
|
|
were decoded. Some protocols such as :mod:`urllib` http ``3xx`` redirects
|
|
potentially allow for an attacker to supply such a name.
|
|
|
|
Individual labels within an IDNA encoded DNS name will now raise an error
|
|
early during IDNA decoding if they are longer than 1024 unicode characters
|
|
given that each decoded DNS label must be 63 or fewer characters and the
|
|
entire decoded DNS name is limited to 255. Only an application presenting a
|
|
hostname or label consisting primarily of :rfc:`3454` section 3.1 "Nothing"
|
|
characters to be removed would run into of this new limit. See also
|
|
:rfc:`5894` section 6 and :rfc:`3491`.

The docs clearly say that ``PyImport_Inittab``,
|
|
:c:func:`PyImport_AppendInittab`, and :c:func:`PyImport_ExtendInittab`
|
|
should not be used after :c:func:`Py_Initialize` has been called. We now
|
|
enforce this for the two functions. Additionally, the runtime now uses an
|
|
internal copy of ``PyImport_Inittab``, to guard against modification.

When calling into Python code from C code, through
|
|
:c:func:`PyEval_EvalFrameEx` or a related C-API function, a shim frame in
|
|
inserted into the call stack. This occurs in the
|
|
``_PyEval_EvalFrameDefault()`` function. The extra frame should be invisible
|
|
to all Python and most C extensions, but out-of-process profilers and
|
|
debuggers need to be aware of it. These shim frames can be detected by
|
|
checking ``frame->owner == FRAME_OWNED_BY_CSTACK``.
|
|
|
|
Extensions implementing their own interpreters using PEP 523 need to be
|
|
aware of this shim frame and the changes to the semantics of
|
|
:opcode:`RETURN_VALUE`, :opcode:`YIELD_VALUE`, and
|
|
:opcode:`RETURN_GENERATOR`, which now clear the frame.

Remove the ``distutils`` package. It was deprecated in Python 3.10 by
|
|
:pep:`632` "Deprecate distutils module". For projects still using
|
|
``distutils`` and cannot be updated to something else, the ``setuptools``
|
|
project can be installed: it still provides ``distutils``. Patch by Victor
|
|
Stinner.

Some configurable capabilities of sub-interpreters have changed. They always
|
|
allow subprocesses (:mod:`subprocess`) now, whereas before subprocesses
|
|
could be optionally disallowed for a sub-interpreter. Instead
|
|
:func:`os.exec` can now be disallowed. Disallowing daemon threads is now
|
|
supported. Disallowing all threads is still allowed, but is never done by
|
|
default. Note that the optional restrictions are only available through
|
|
``_Py_NewInterpreterFromConfig()``, which isn't a public API. They do not
|
|
affect the main interpreter, nor :c:func:`Py_NewInterpreter`.

A ``_PyInterpreterConfig`` has been added and ``_Py_NewInterpreter()`` has
|
|
been renamed to ``_Py_NewInterpreterFromConfig()``. The
|
|
"isolated_subinterpreters" argument is now a granular config that captures
|
|
the previous behavior. Note that this is all "private" API.

``Py_InitializeEx`` now correctly calls ``PyConfig_Clear`` after
|
|
initializing the interpreter (the omission didn't cause a memory leak only
|
|
because none of the dynamically allocated config fields are populated by the
|
|
wrapper function)

Add :c:func:`PyFrame_GetVar` and :c:func:`PyFrame_GetVarString` functions to
|
|
get a frame variable by its name. Patch by Victor Stinner.
