- Add CVE-2015-20107-mailcap-unsafe-filenames.patch to avoid
CVE-2015-20107 (bsc#1198511, gh#python/cpython#68966), the
command injection in the mailcap module.
- Fix building of documentation and the universal configuration of the
%primary_interpreter.
- (bsc#1196784, CVE-2022-25236) Rename patch:
support-expat-245.patch to support-expat-CVE-2022-25236-patched.patch
and update the patch to detect expat >= 2.4.4 instead of >= 2.4.5
as it was fully patched against CVE-2022-25236.

- Update to 3.9.13:
- Core and Builtins
- gh-92311: Fixed a bug where setting frame.f_lineno to jump
over a list comprehension could misbehave or crash.
- gh-92112: Fix crash triggered by an evil custom mro() on
a metaclass.
- gh-92036: Fix a crash in subinterpreters related to the
garbage collector. When a subinterpreter is deleted,
untrack all objects tracked by its GC. To prevent a crash
in deallocator functions expecting objects to be tracked by
the GC, leak a strong reference to these objects on
purpose, so they are never deleted and their deallocator
functions are not called. Patch by Victor Stinner.
- gh-91421: Fix a potential integer overflow in
_Py_DecodeUTF8Ex.
- bpo-46775: Some Windows system error codes(>= 10000) are
now mapped into the correct errno and may now raise
a subclass of OSError. Patch by Dong-hee Na.
- bpo-46962: Classes and functions that unconditionally
declared their docstrings ignoring the
--without-doc-strings compilation flag no longer do so.
- The classes affected are pickle.PickleBuffer,
testcapi.RecursingInfinitelyError, and types.GenericAlias.
- The functions affected are 24 methods in ctypes.
- Patch by Oleg Iarygin.
- bpo-36819: Fix crashes in built-in encoders with error
handlers that return position less or equal than the
starting position of non-encodable characters.
- Library
- gh-91581: utcfromtimestamp() no longer attempts to resolve
fold in the pure Python implementation, since the fold is
never 1 in UTC. In addition to being slightly faster in the
common case, this also prevents some errors when the
timestamp is close to datetime.min. Patch by Paul Ganssle.
- gh-92530: Fix an issue that occurred after interrupting
threading.Condition.notify().
- gh-92049: Forbid pickling constants re._constants.SUCCESS
etc. Previously, pickling did not fail, but the result
could not be unpickled.
- bpo-47029: Always close the read end of the pipe used by
multiprocessing.Queue after the last write of buffered data
to the write end of the pipe to avoid BrokenPipeError at
garbage collection and at multiprocessing.Queue.close()
calls. Patch by Géry Ogam.
- gh-91910: Add missing f prefix to f-strings in error
messages from the multiprocessing and asyncio modules.
- gh-91810: ElementTree method write() and function
tostring() now use the text file’s encoding (“UTF-8” if not
available) instead of locale encoding in XML declaration
when encoding="unicode" is specified.
- gh-91832: Add required attribute to argparse.Action repr
output.
- gh-91734: Fix OSS audio support on Solaris.
- gh-91700: Compilation of regular expression containing
a conditional expression (?(group)...) now raises an
appropriate re.error if the group number refers to not
defined group. Previously an internal RuntimeError was
raised.
- gh-91676: Fix unittest.IsolatedAsyncioTestCase to shutdown
the per test event loop executor before returning from its
run method so that a not yet stopped or garbage collected
executor state does not persist beyond the test.
- gh-90568: Parsing \N escapes of Unicode Named Character
Sequences in a regular expression raises now re.error
instead of TypeError.
- gh-91595: Fix the comparison of character and integer
inside Tools.gdb.libpython.write_repr(). Patch by Yu Liu.
- gh-90622: Worker processes for
concurrent.futures.ProcessPoolExecutor are no longer
spawned on demand (a feature added in 3.9) when the
multiprocessing context start method is "fork" as that can
lead to deadlocks in the child processes due to a fork
happening while threads are running.
- gh-91575: Update case-insensitive matching in the re module
to the latest Unicode version.
- gh-91581: Remove an unhandled error case in the
C implementation of calls to datetime.fromtimestamp with no
time zone (i.e. getting a local time from an epoch
timestamp). This should have no user-facing effect other
than giving a possibly more accurate error message when
called with timestamps that fall on 10000-01-01 in the
local time. Patch by Paul Ganssle.
- bpo-34480: Fix a bug where _markupbase raised an
UnboundLocalError when an invalid keyword was found in
marked section. Patch by Marek Suscak.
- bpo-27929: Fix asyncio.loop.sock_connect() to only resolve
names for socket.AF_INET or socket.AF_INET6 families.
Resolution may not make sense for other families, like
socket.AF_BLUETOOTH and socket.AF_UNIX.
- bpo-43323: Fix errors in the email module if the charset
itself contains undecodable/unencodable characters.
- bpo-46787: Fix concurrent.futures.ProcessPoolExecutor
exception memory leak
- bpo-46415: Fix ipaddress.ip_{address,interface,network}
raising TypeError instead of ValueError if given invalid
tuple as address parameter.
- bpo-44911: IsolatedAsyncioTestCase will no longer throw an
exception while cancelling leaked tasks. Patch by Bar
Harel.
- bpo-44493: Add missing terminated NUL in sockaddr_un’s
length
- This was potentially observable when using non-abstract
AF_UNIX datagram sockets to processes written in another
programming language.
- bpo-42627: Fix incorrect parsing of Windows registry proxy
settings
- bpo-36073: Raise ProgrammingError instead of segfaulting on
recursive usage of cursors in sqlite3 converters. Patch by
Sergey Fedoseev.

GitHub issues.

the function shutil.unpack_archive()
- gh-91547: Remove “Undocumented modules” page.
- bpo-44347: Clarify the meaning of dirs_exist_ok, a kwarg of

os.path to remove warnings that became irrelevant after the
implementations of PEP 383 and PEP 529.
- bpo-47138: Pin Jinja to a version compatible with Sphinx
version 2.4.4.
- bpo-46962: All docstrings in code snippets are now wrapped
into PyDoc_STR() to follow the guideline of PEP 7’s
Documentation Strings paragraph. Patch by Oleg Iarygin.
- bpo-26792: Improve the docstrings of runpy.run_module() and
runpy.run_path(). Original patch by Andrew Brezovsky.
- bpo-45790: Adjust inaccurate phrasing in Defining Extension
Types: Tutorial about the ob_base field and the macros used
to access its contents.
- bpo-42340: Document that in some circumstances
KeyboardInterrupt may cause the code to enter an
inconsistent state. Provided a sample workaround to avoid
it if needed.
- bpo-41233: Link the errnos referenced in
Doc/library/exceptions.rst to their respective section in
Doc/library/errno.rst, and vice versa. Previously this was
only done for EINTR and InterruptedError. Patch by Yan
“yyyyyyyan” Orestes.
- bpo-38056: Overhaul the Error Handlers documentation in
codecs.
- bpo-13553: Document tkinter.Tk args.
- Tests
- gh-91607: Fix test_concurrent_futures to test the correct
multiprocessing start method context in several cases where
the test logic mixed this up.
- bpo-47205: Skip test for sched_getaffinity() and
sched_setaffinity() error case on FreeBSD.
- bpo-29890: Add tests for ipaddress.IPv4Interface and
ipaddress.IPv6Interface construction with tuple arguments.
Original patch and tests by louisom.

- bpo-47103: Windows PGInstrument builds now copy a required
DLL into the output directory, making it easier to run the
profile stage of a PGO build.

CVE-2018-25032.

where this header doesn’t exist. Patch by Pablo Galindo

- Replaced usage of tempfile.mktemp() with TemporaryDirectory
to avoid a potential race condition.
- Add auditing events to the marshal module, and stop raising
code.__init__ events for every unmarshalled code object.
Directly instantiated code objects will continue to raise
an event, and audit event handlers should inspect or
collect the raw marshal data. This reduces a significant
performance overhead when loading from .pyc files.
- Made the internal putcmd function in smtplib sanitize input
for presence of \r and \n characters to avoid (unlikely)
command injection.

WeakSet when two threads attempt to commit the last pending

loss in asyncio.run where shutdown_asyncgens is not run
