:cve:`2020-8492`: The :class:`~urllib.request.AbstractBasicAuthHandler` class

of the :mod:`urllib.request` module uses an inefficient regular expression

which can be exploited by an attacker to cause a denial of service. Fix the

regex to prevent the catastrophic backtracking. Vulnerability reported by

Switch to a new parser, based on PEG. For more details see PEP 617. To
|
||
temporarily switch back to the old parser, use ``-X oldparser`` or
|

``PYTHONOLDPARSER=1``. In Python 3.10 we will remove the old parser
|
||
completely, including the ``parser`` module (already deprecated) and
|

anything that depends on it.

Optimize the :mod:`subprocess` module on FreeBSD using ``closefrom()``. A
|
||
single ``close(fd)`` syscall is cheap, but when ``sysconf(_SC_OPEN_MAX)`` is
|
||
high, the loop calling ``close(fd)`` on each file descriptor can take
|
||
several milliseconds.
|
||
|
||
The workaround on FreeBSD to improve performance was to load and mount the
|
||
fdescfs kernel module, but this is not enabled by default.

Fix ``which.py`` script exit code: it now uses

:func:`os.waitstatus_to_exitcode` to convert :func:`os.system` exit status

Add the functions :c:func:`PyObject_GC_IsTracked` and

:c:func:`PyObject_GC_IsFinalized` to the public API to allow to query if

Python objects are being currently tracked or have been already finalized by

the garbage collector respectively. Patch by Pablo Galindo.

The :c:func:`!PyObject_NEW` macro becomes an alias to the
|

:c:func:`PyObject_New` macro, and the :c:func:`!PyObject_NEW_VAR` macro
|

becomes an alias to the :c:func:`PyObject_NewVar` macro, to hide
|

implementation details. They no longer access directly the

:c:member:`PyTypeObject.tp_basicsize` member.
