- Update to 3.8.11
* Security
- bpo-44022 (boo#1189241): mod:http.client now avoids
infinitely reading potential HTTP headers after a 100
Continue status response from the server.
- bpo-43882: The presence of newline or tab characters in parts
of a URL could allow some forms of attacks.
Following the controlling specification for URLs defined by
WHATWG urllib.parse() now removes ASCII newlines and tabs
from URLs, preventing such attacks.
- bpo-42800: Audit hooks are now fired for frame.f_code,
traceback.tb_frame, and generator code/frame attribute
access.
* Core and Builtins
- bpo-44070: No longer eagerly makes import filenames absolute,
except for extension modules, which was introduced in 3.8.10.
* Library
- bpo-44061: Fix regression in previous release when calling
pkgutil.iter_modules() with a list of pathlib.Path objects

- Update to 3.8.10:
- Security
- bpo-43434: Creating a sqlite3.Connection object now also
produces a sqlite3.connect auditing event. Previously this
event was only produced by sqlite3.connect() calls. Patch
by Erlend E. Aasland.
- bpo-43472: Ensures interpreter-level audit hooks receive
the cpython.PyInterpreterState_New event when called
through the _xxsubinterpreters module.
- bpo-43075: Fix Regular Expression Denial of Service (ReDoS)
vulnerability in urllib.request.AbstractBasicAuthHandler.
The ReDoS-vulnerable regex has quadratic worst-case
complexity and it allows cause a denial of service when
identifying crafted invalid RFCs. This ReDoS issue is on
the client side and needs remote attackers to control the
HTTP server.
- Core and Builtins
- bpo-43105: Importlib now resolves relative paths when
creating module spec objects from file locations.
- bpo-42924: Fix bytearray repetition incorrectly copying
data from the start of the buffer, even if the data is
offset within the buffer (e.g. after reassigning a slice at
the start of the bytearray to a shorter byte string).
- Library
- bpo-43993: Update bundled pip to 21.1.1.
- bpo-43937: Fixed the turtle module working with non-default
root window.
- bpo-43930: Update bundled pip to 21.1 and setuptools to
56.0.0
- bpo-43920: OpenSSL 3.0.0: load_verify_locations() now
returns a consistent error message when cadata contains no
valid certificate.
- bpo-43607: urllib can now convert Windows paths with \\?\
prefixes into URL paths.
- bpo-43284: platform.win32_ver derives the windows version
from sys.getwindowsversion().platform_version which in turn
derives the version from kernel32.dll (which can be of
a different version than Windows itself). Therefore change
the platform.win32_ver to determine the version using the
platform module’s _syscmd_ver private function to return an
accurate version.
- bpo-42248: [Enum] ensure exceptions raised in _missing__
are released
- bpo-43799: OpenSSL 3.0.0: define OPENSSL_API_COMPAT 1.1.1
to suppress deprecation warnings. Python requires OpenSSL
1.1.1 APIs.
- bpo-43794: Add ssl.OP_IGNORE_UNEXPECTED_EOF constants
(OpenSSL 3.0.0)
- bpo-43789: OpenSSL 3.0.0: Don’t call the password callback
function a second time when first call has signaled an
error condition.
- bpo-43788: The header files for ssl error codes are now
OpenSSL version-specific. Exceptions will now show correct
reason and library codes. The make_ssl_data.py script has
been rewritten to use OpenSSL’s text file with error codes.
- bpo-43655: tkinter dialog windows are now recognized as
dialogs by window managers on macOS and X Window.
- bpo-43534: turtle.textinput() and turtle.numinput() create
now a transient window working on behalf of the canvas
window.
- bpo-43522: Fix problem with hostname_checks_common_name.
OpenSSL does not copy hostflags from struct SSL_CTX to
struct SSL.
- bpo-42967: Allow bytes separator argument in
urllib.parse.parse_qs and urllib.parse.parse_qsl when
parsing str query strings. Previously, this raised
a TypeError.
- bpo-43176: Fixed processing of a dataclass that inherits
from a frozen dataclass with no fields. It is now correctly
detected as an error.
- bpo-34463: Fixed discrepancy between traceback and the
interpreter in formatting of SyntaxError with lineno not
set (traceback was changed to match interpreter).
- bpo-41735: Fix thread locks in zlib module may go wrong in
rare case. Patch by Ma Lin.
- bpo-26053: Fixed bug where the pdb interactive run command
echoed the args from the shell command line, even if those
have been overridden at the pdb prompt.
- bpo-36470: Fix dataclasses with InitVars and replace().
Patch by Claudiu Popa.
- bpo-28577: The hosts method on 32-bit prefix length
IPv4Networks and 128-bit prefix IPv6Networks now returns
a list containing the single Address instead of an empty
list.
- bpo-32745: Fix a regression in the handling of ctypes’
ctypes.c_wchar_p type: embedded null characters would cause
a ValueError to be raised. Patch by Zackery Spytz.
- Documentation
- bpo-43959: The documentation on the PyContextVar C-API was
clarified.
- bpo-43938: Update dataclasses documentation to express that
FrozenInstanceError is derived from AttributeError.
- bpo-43739: Fixing the example code in
Doc/extending/extending.rst to declare and initialize the
pmodule variable to be of the right type.
- Tests
- bpo-43842: Fix a race condition in the SMTP test of
test_logging. Don’t close a file descriptor (socket) from
a different thread while asyncore.loop() is polling the
file descriptor. Patch by Victor Stinner.
- bpo-43811: Tests multiple OpenSSL versions on GitHub
Actions. Use ccache to speed up testing.
- bpo-43791: OpenSSL 3.0.0: Disable testing of legacy
protocols TLS 1.0 and 1.1. Tests are failing with
TLSV1_ALERT_INTERNAL_ERROR.
- IDLE
- bpo-43655: IDLE dialog windows are now recognized as
dialogs by window managers on macOS and X Window.
- C API
- bpo-43962: _PyInterpreterState_IDIncref() now calls
_PyInterpreterState_IDInitref() and always increments
id_refcount. Previously, calling
_xxsubinterpreters.get_current() could create an
id_refcount inconsistency when
a _xxsubinterpreters.InterpreterID object was deallocated.
Patch by Victor Stinner.
- Reapplied patches:
- CVE-2019-5010-null-defer-x509-cert-DOS.patch
- F00102-lib64.patch
- SUSE-FEDORA-multilib.patch
- bpo-31046_ensurepip_honours_prefix.patch
- python-3.3.0b1-fix_date_time_compiler.patch
- Make sure to close the import_failed.map file after the exception
has been raised in order to avoid ResourceWarnings when the
failing import is part of a try...except block.

- Update to 3.8.9:
- bpo#42988 (bsc#1183374) CVE-2021-3426: Remove the getfile
feature of the pydoc module which could be abused to read
arbitrary files on the disk (directory traversal
vulnerability). Moreover, even source code of Python modules
can contain sensitive data like passwords. Vulnerability
reported by David Schwörer.
- bpo-43285: ftplib no longer trusts the IP address value
returned from the server in response to the PASV command by
default. This prevents a malicious FTP server from using the
response to probe IPv4 address and port combinations on the
client network.
- Code that requires the former vulnerable behavior may set
a trust_server_pasv_ipv4_address attribute on their
ftplib.FTP instances to True to re-enable it.
- bpo-43439: Add audit hooks for gc.get_objects(),
gc.get_referrers() and gc.get_referents(). Patch by Pablo
Galindo.
- bpo-43660: Fix crash that happens when replacing sys.stderr
with a callable that can remove the object while an exception
is being printed. Patch by Pablo Galindo.
- bpo-35883: Python no longer fails at startup with a fatal
error if a command line argument contains an invalid Unicode
character. The Py_DecodeLocale() function now escapes byte
sequences which would be decoded as Unicode characters
outside the [U+0000; U+10ffff] range.
- bpo-43406: Fix a possible race condition where
PyErr_CheckSignals tries to execute a non-Python signal
handler.
- bpo-35930: Raising an exception raised in a “future” instance
will create reference cycles.
- bpo-43577: Fix deadlock when using ssl.SSLContext debug
callback with ssl.SSLContext.sni_callback().
- bpo-43423: subprocess.communicate() no longer raises an
IndexError when there is an empty stdout or stderr IO buffer
during a timeout on Windows.
- bpo-27820: Fixed long-standing bug of smtplib.SMTP where
doing AUTH LOGIN with initial_response_ok=False will fail.
The cause is that SMTP.auth_login _always_ returns a password
if provided with a challenge string, thus non-compliant with
the standard for AUTH LOGIN. Also fixes bug with the test for
smtpd.
- bpo-43399: Fix ElementTree.extend not working on iterators
when using the Python implementation
- bpo-43316: The python -m gzip command line application now
properly fails when detecting an unsupported extension. It
exits with a non-zero exit code and prints an error message
to stderr.
- bpo-43260: Fix TextIOWrapper can not flush internal buffer
forever after very large text is written.
- bpo-42782: Fail fast in shutil.move() to avoid creating
destination directories on failure.
- bpo-37193: Fixed memory leak in socketserver.ThreadingMixIn
introduced in Python 3.7.
- bpo-43199: Answer “Why is there no goto?” in the Design and
History FAQ.
- bpo-43407: Clarified that a result from time.monotonic(),
time.perf_counter(), time.process_time(), or
time.thread_time() can be compared with the result from any
following call to the same function - not just the next
immediate call.
- bpo-27646: Clarify that ‘yield from <expr>’ works with any
iterable, not just iterators.
- bpo-36346: Update some deprecated unicode APIs which are
documented as “will be removed in 4.0” to “3.12”. See PEP 623
for detail.
- bpo-37945: Fix test_getsetlocale_issue1813() of test_locale:
skip the test if setlocale() fails. Patch by Victor Stinner.
- bpo-41561: Add workaround for Ubuntu’s custom OpenSSL
security level policy.
- bpo-43631: Update macOS, Windows, and CI to OpenSSL 1.1.1k.
- bpo-43617: Improve configure.ac: Check for presence of
autoconf-archive package and remove our copies of M4 macros.
- bpo-41837: Update macOS installer build to use OpenSSL
1.1.1j.
- bpo-42225: Document that IDLE can fail on Unix either from
misconfigured IP masquerage rules or failure displaying
complex colored (non-ascii) characters.
- bpo-43283: Document why printing to IDLE’s Shell is often
slower than printing to a system terminal and that it can be
made faster by pre-formatting a single string before
printing.

Unnecessary dependency.
- Update to 3.8.7:
- bugfix release
- multiple patches realigned:
- F00102-lib64.patch
- SUSE-FEDORA-multilib.patch
- bpo-31046_ensurepip_honours_prefix.patch
- skip_random_failing_tests.patch
- Last try before this results in an editwar:
* remove importlib_resources and importlib-metadata
provides/obsoletes
* import importlib_resources is not the same as
import importlib.resources, same for metadata
* The backport packages from PyPI needed for older flavors are
specified as such for setuptools or in pyproject.toml. If a
package requires them they typically add them with a python
version qualifier and the packages have their own version
numbers.
- Add patch sphinx-update-removed-function.patch to no longer call
a now removed function and to make documentation build independent of
the Sphinx version (bsc#1179630, gh#python/cpython#13236).
- Add importlib_resources provide/obsolete as it is integral
part of the lang since 3.7 release
