bpo-40091: Fix a hang at fork in the logging module (GH-19416)
Fix a hang at fork in the logging module: the new private
_at_fork_reinit() method is now used to reinitialize locks at fork in
the child process.

The createLock() method is no longer used at fork.

bpo-39481: fix test_genericalias on Android (GH-19469)
Android bionic does not implement shm_open/shm_unlink [1].
As a result _posixshmem extension does not exist and
multiprocessing.shared_memory cannot be imported.

bpo-40241: Add pycore_gc.h header file (GH-19494)
Move the PyGC_Head structure and the following private macros to the
internal C API:

* _PyGCHead_FINALIZED()
* _PyGCHead_NEXT()
* _PyGCHead_PREV()
* _PyGCHead_SET_FINALIZED()
* _PyGCHead_SET_NEXT()
* _PyGCHead_SET_PREV()
* _PyGC_FINALIZED()
* _PyGC_PREV_MASK
* _PyGC_PREV_MASK_COLLECTING
* _PyGC_PREV_MASK_FINALIZED
* _PyGC_PREV_SHIFT
* _PyGC_SET_FINALIZED()
* _PyObject_GC_IS_TRACKED()
* _PyObject_GC_MAY_BE_TRACKED()
* _Py_AS_GC(o)

Keep the private _PyGC_FINALIZED() macro in the public C API for
backward compatibility with Python 3.8: make it an alias to the new
PyObject_GC_IsFinalized() function.

Move the SIZEOF_PYGC_HEAD constant from _testcapi module to
_testinternalcapi module.

bpo-39011: Preserve line endings within ElementTree attributes (GH-18468)
* bpo-39011: Preserve line endings within attributes

Line endings within attributes were previously normalized to "\n" in Py3.7/3.8.
This patch removes that normalization, as line endings which were
replaced by entity numbers should be preserved in original form.

bpo-40089: Add _at_fork_reinit() method to locks (GH-19195)
Add a private _at_fork_reinit() method to _thread.Lock,
_thread.RLock, threading.RLock and threading.Condition classes:
reinitialize the lock after fork in the child process; reset the lock
to the unlocked state.

Rename also the private _reset_internal_locks() method of
threading.Event to _at_fork_reinit().

* Add _PyThread_at_fork_reinit() private function. It is excluded
  from the limited C API.
* threading.Thread._reset_internal_locks() now calls
  _at_fork_reinit() on self._tstate_lock rather than creating a new
  Python lock object.

Guido van Rossum 48b069a003
bpo-39481: Implementation for PEP 585 (#18239)
This implements things like `list[int]`,
which returns an object of type `types.GenericAlias`.
This object mostly acts as a proxy for `list`,
but has attributes `__origin__` and `__args__`
that allow recovering the parts (with values `list` and `(int,)`.

There is also an approximate notion of type variables;
e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`.
Type variables are objects of type `typing.TypeVar`.

bpo-40140: test_builtin.PtyTests registers SIGHUP handler (GH-19314)
test_builtin.PtyTests now registers an handler for SIGHUP signal.
Closing the PTY file descriptor can emit a SIGHUP signal: just ignore
it.

run_child() now also closes the PTY file descriptor before waiting
for the process completition, otherwise the test hangs on AIX.

lib2to3: Support named assignment expressions (GH-12702)
There are two copies of the grammar -- the one used by Python itself as
Grammar/Grammar, and the one used by lib2to3 which has necessarily diverged at
Lib/lib2to3/Grammar.txt because it needs to support older syntax an we want it
to be reasonable stable to avoid requiring fixer rewrites.

This brings suport for syntax like `if x:= foo():` to match what the live
Python grammar does.

This should've been added at the time of the walrus operator itself, but lib2to3 being
independent is often overlooked.  So we do consider this a bugfix rather than enhancement.

"CGI script exit code -11."

bpo-39503: CVE-2020-8492: Fix AbstractBasicAuthHandler (GH-18284)
The AbstractBasicAuthHandler class of the 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 Ben Caller
and Matt Schwager.

AbstractBasicAuthHandler of urllib.request now parses all
WWW-Authenticate HTTP headers and accepts multiple challenges per
header: use the realm of the first Basic challenge.
