python39 py39-html-docs: updated to 3.9.16

Python 3.9.16 final

gh-100001: python -m http.server no longer allows terminal control characters sent within a garbage request to be printed to the stderr server log.

This is done by changing the http.server BaseHTTPRequestHandler .log_message method to replace control characters with a \xHH hex escape before printing.
gh-87604: Avoid publishing list of active per-interpreter audit hooks via the gc module
gh-98433: The IDNA codec decoder used on DNS hostnames by socket or 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 urllib http 3xx redirects potentially allow for an attacker to supply such a name.
gh-98739: Update bundled libexpat to 2.5.0
gh-98517: Port XKCP fix for the buffer overflows in SHA-3 (CVE-2022-37454).
gh-97514: On Linux the multiprocessing module returns to using filesystem backed unix domain sockets for communication with the forkserver process instead of the Linux abstract socket namespace. Only code that chooses to use the orkserverstart method is affected.

Abstract sockets have no permissions and could allow any user on the system in the same network namespace (often the whole system) to inject code into the multiprocessing forkserver process. This was a potential privilege escalation. Filesystem based socket permissions restrict this to the forkserver process user as was the default in Python 3.8 and earlier.

This prevents Linux CVE-2022-42919.
gh-68966: The deprecated mailcap module now refuses to inject unsafe text (filenames, MIME types, parameters) into shell commands. Instead of using such text, it will warn and act as if a match was not found (or for test commands, as if the test failed).

Python 3.9.15


gh-97616: Fix multiplying a list by an integer (list *= int): detect the integer overflow when the new allocated length is close to the maximum size. Issue reported by Jordan Limor. Patch by Victor Stinner.
gh-97612: Fix a shell code injection vulnerability in the example script. The script no longer uses a shell to run openssl commands. Issue reported and initial fix by Caleb Shortt. Patch by Victor Stinner.
Core and Builtins
gh-96848: Fix command line parsing: reject -X int_max_str_digits option with no value (invalid) when the PYTHONINTMAXSTRDIGITS environment variable is set to a valid limit. Patch by Victor Stinner.
gh-95778: When ValueError is raised if an integer is larger than the limit, mention the sys.set_int_max_str_digits() function in the error message. Patch by Victor Stinner.


gh-97005: Update bundled libexpat to 2.4.9


gh-96577: Fixes a potential buffer overrun in msilib.


gh-97897: The macOS 13 SDK includes support for the mkfifoat and mknodat system calls. Using the dir_fd option with either os.mkfifo() or os.mknod() could result in a segfault if cpython is built with the macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding runtime support for detection of these system calls (eaklinking as is done for other newer syscalls on macOS.

python39 py39-html-docs: updated to 3.9.14

Python 3.9.14

gh-95778: Converting between int and str in bases other than 2 (binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now raises a ValueError if the number of digits in string form is above a limit to avoid potential denial of service attacks due to the algorithmic complexity. This is a mitigation for CVE-2020-10735.

This new limit can be configured or disabled by environment variable, command line flag, or sys APIs. See the integer string conversion length limitation documentation. The default limit is 4300 digits in string form.

Patch by Gregory P. Smith [Google] and Christian Heimes [Red Hat] with feedback from Victor Stinner, Thomas Wouters, Steve Dower, Ned Deily, and Mark Dickinson.
gh-87389: http.server: Fix an open redirection vulnerability in the HTTP server when an URI path starts with //. Vulnerability discovered, and initial fix proposed, by Hamza Avvan.

Core and Builtins
gh-93065: Fix contextvars HAMT implementation to handle iteration over deep trees.

The bug was discovered and fixed by Eli Libman. See MagicStack/immutables#84 for more details.

gh-94821: Fix binding of unix socket to empty address on Linux to use an available address from the abstract namespace, instead of 
gh-91810: Suppress writing an XML declaration in open files in ElementTree.write() with encoding='unicode' and xml_declaration=None.
bpo-45393: Fix the formatting for await x and not x in the operator precedence table when using the help() system.
bpo-46197: Fix ensurepip environment isolation for subprocess running pip.

gh-95280: Fix problem with test_ssl test_get_ciphers on systems that require perfect forward secrecy (PFS) ciphers.
gh-94208: test_ssl is now checking for supported TLS version and protocols in more tests.
bpo-47016: Create a GitHub Actions workflow for verifying bundled pip and setuptools. Patch by Illia Volochii and Adam Turner.

Python 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.


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 encoding (׶TF-8if 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-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 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 yyyyyyanOrestes.
bpo-38056: Overhaul the Error Handlers documentation in codecs.
bpo-13553: Document tkinter.Tk args.


gh-91607: Fix test_concurrent_futures to test the correct multiprocessing start method context in several cases where the test logic mixed this up.

Python 3.9.10 final

Core and Builtins

bpo-46070: Py_EndInterpreter() now explicitly untracks all objects currently tracked by the GC. Previously, if an object was used later by another interpreter, calling PyObject_GC_UnTrack() on the object crashed if the previous or the next object of the PyGC_Head structure became a dangling pointer. Patch by Victor Stinner.

Previously, when built on older macOS systems, find_library was not able to find macOS system libraries when running on Big Sur due to changes in how system libraries are stored.


bpo-44756: In the Makefile for documentation (Doc/Makefile), the build rule is dependent on the venv rule. Therefore, html, latex, and other build-dependent rules are also now dependent on venv. The venv rule only performs an action if $(VENVDIR) does not exist. Doc/README.rst was updated; most users now only need to type make html.

python39: updated to 3.9.6

Python 3.9.6 final


bpo-44022: mod:http.client now avoids infinitely reading potential HTTP headers after a 100 Continue status response from the server.
Core and Builtins
bpo-44409: Fix error location information for tokenizer errors raised on initialization of the tokenizer. Patch by Pablo Galindo.
bpo-43667: Improve Unicode support in non-UTF locales on Oracle Solaris. This issue does not affect other Solaris systems.
bpo-44168: Fix error message in the parser involving keyword arguments with invalid expressions. Patch by Pablo Galindo
bpo-44114: Fix incorrect dictkeys_reversed and dictitems_reversed function signatures in C code, which broke webassembly builds.
bpo-44070: No longer eagerly makes import filenames absolute, except for extension modules, which was introduced in 3.9.5.
bpo-28146: Fix a confusing error message in str.format().
bpo-11105: When compiling ast.AST objects with recursive references through compile(), the interpreter doesn crash anymore instead it raises a RecursionError.


bpo-44516: Update vendored pip to 21.1.3
bpo-44482: Fix very unlikely resource leak in glob in alternate Python implementations.
bpo-44439: Fix in bz2.BZ2File.write() / lzma.LZMAFile.write() methods, when the input data is an object that supports the buffer protocol, the file length may be wrong.
bpo-44434: _thread.start_new_thread() no longer calls PyThread_exit_thread() explicitly at the thread exit, the call was redundant. On Linux with the glibc, pthread_exit() aborts the whole process if dlopen() fails to open file (ex: EMFILE error). Patch by Victor Stinner.
bpo-44422: The threading.enumerate() function now uses a reentrant lock to prevent a hang on reentrant call. Patch by Victor Stinner.
bpo-44395: Fix as_string() to pass unixfrom properly. Patch by Dong-hee Na.
bpo-44342: [Enum] Be more robust in searching for pickle support before making an enum class unpicklable.
bpo-44356: [Enum] Allow multiple data-type mixins if they are all the same.
bpo-44254: On Mac, give turtledemo button text a color that works on both light or dark background. Programmers cannot control the latter.
bpo-44145: hmac computations were not releasing the GIL while calling the OpenSSL HMAC_Update C API (a new feature in 3.9). This unintentionally prevented parallel computation as other hashlib algorithms support.
bpo-37788: Fix a reference leak when a Thread object is never joined.
bpo-44061: Fix regression in previous release when calling pkgutil.iter_modules() with a list of pathlib.Path objects

bpo-44018: random.seed() no longer mutates bytearray inputs.
bpo-38352: Add IO, BinaryIO, TextIO, Match, and Pattern to typing.__all__. Patch by Jelle Zijlstra.
bpo-43972: When http.server.SimpleHTTPRequestHandler sends a 301 (Moved Permanently) for a directory path not ending with /, add a Content-Length: 0 header. This improves the behavior for certain clients.
bpo-28528: Fix a bug in pdb where checkline() raises AttributeError if it is called after reset().
bpo-43776: When subprocess.Popen args are provided as a string or as pathlib.Path, the Popen instance repr now shows the right thing.
bpo-43666: AIX: Lib/_aix_support.get_platform() may fail in an AIX WPAR. The fileset bos.rte appears to have a builddate in both LPAR and WPAR so this fileset is queried rather than bos.mp64. To prevent a similiar situation (no builddate in ODM) a value (9988) sufficient for completing a build is provided. Patch by M Felt.
bpo-43650: Fix MemoryError in shutil.unpack_archive() which fails inside shutil._unpack_zipfile() on large files. Patch by Igor Bolshakov.
bpo-43318: Fix a bug where pdb does not always echo cleared breakpoints.
bpo-43295: datetime.datetime.strptime() now raises ValueError instead of IndexError when matching 'z' with the %z format specifier.
bpo-37022: pdb now displays exceptions from repr() with its p and pp commands.
bpo-40620: Convert examples in tutorial controlflow.rst section 4.3 to be interpreter-demo style.
bpo-13814: In the Design FAQ, answer ׸hy don generators support the with statement?bpo-44392: Added a new section in the C API documentation for types used in type hinting. Documented Py_GenericAlias and Py_GenericAliasType.
bpo-38291: Mark and as deprecated since Python 3.8 in the documentation. They were never properly supported by type checkers.
bpo-44322: Document that SyntaxError args have a details tuple and that details are adjusted for errors in f-string field replacement expressions.
bpo-44195: Corrected references to TraversableResources in docs. There is no TraversableReader.
bpo-41963: Document that ConfigParser strips off comments when reading configuration files.
bpo-44072: Correct where in the numeric ABC hierarchy ** support is added, i.e., in numbers.Complex, not numbers.Integral.
bpo-43558: Add the remark to dataclasses documentation that the __init__() of any base class has to be called in __post_init__(), along with a code example.
bpo-41621: Document that collections.defaultdict parameter default_factory defaults to None and is positional-only.


bpo-44287: Fix asyncio test_popen() of test_windows_utils by using a longer timeout. Use military grade battle-tested timeout rather than a hardcoded timeout of 10 seconds: it 30 seconds by default, but it is made longer on slow buildbots. Patch by Victor Stinner.
bpo-44363: Account for address sanitizer in test_capi. test_capi now passes when run GCC address sanitizer.


bpo-44381: The Windows build now accepts EnableControlFlowGuard set to guard to enable CFG.
bpo-41299: Fix 16ms jitter when using timeouts in threading, such as with threading.Lock.acquire() or threading.Condition.wait().


bpo-43568: Relax unnecessarily restrictive MACOSX_DEPLOYMENT_TARGET check when building extension modules for macOS. Patch by Joshua Root.
bpo-43109: Allow ith-lto configure option to work with Apple-supplied Xcode or Command Line Tools.


bpo-40128: Mostly fix completions on macOS when not using tcl/tk 8.6.11 (as with 3.9). The added update_idletask call should be harmless and possibly helpful otherwise.
bpo-33962: Move the indent space setting from the Font tab to the new Windows tab. Patch by Mark Roseman and Terry Jan Reedy.
bpo-40468: Split the settings dialog General tab into Windows and Shell/ED tabs. Move help sources, which extend the Help menu, to the Extensions tab. Make space for new options and shorten the dialog. The latter makes the dialog better fit small screens.
bpo-41611: Avoid uncaught exceptions in AutoCompleteWindow.winconfig_event().
bpo-41611: Fix IDLE sometimes freezing upon tab-completion on macOS.


bpo-44074: Make patchcheck automatically detect the correct base branch name (previously it was hardcoded to aster


bpo-44441: Py_RunMain() now resets PyImport_Inittab to its initial value at exit. It must be possible to call PyImport_AppendInittab() or PyImport_ExtendInittab() at each Python initialization. Patch by Victor Stinner.
bpo-42083: Fix crash in PyStructSequence_NewType() when passed NULL in the documentation string slot.

python39: updated to 3.9.5

Python 3.9.5 final

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-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-43472: Ensures interpreter-level audit hooks receive the cpython.PyInterpreterState_New event when called through the _xxsubinterpreters module.
bpo-36384: ipaddress module no longer accepts any leading zeros in IPv4 address strings. Leading zeros are ambiguous and interpreted as octal notation by some libraries. For example the legacy function socket.inet_aton() treats leading zeros as octal notatation. glibc implementation of modern inet_pton() does not accept any leading zeros. For a while the ipaddress module used to accept ambiguous leading zeros.
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.
bpo-42800: Audit hooks are now fired for frame.f_code, traceback.tb_frame, and generator code/frame attribute access.

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).

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 _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 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 script has been rewritten to use OpenSSL 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-41735: Fix thread locks in zlib module may go wrong in rare case. Patch by Ma Lin.
bpo-36470: Fix dataclasses with InitVars and replace(). Patch by Claudiu Popa.
bpo-32745: Fix a regression in the handling of ctypesctypes.c_wchar_p type: embedded null characters would cause a ValueError to be raised. Patch by Zackery Spytz.

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-43755: Update documentation to reflect that unparenthesized lambda expressions can no longer be the expression part in an if clause in comprehensions and generator expressions since Python 3.9.
bpo-43739: Fixing the example code in Doc/extending/extending.rst to declare and initialize the pmodule variable to be of the right type.

bpo-43961: Fix test_logging.test_namer_rotator_inheritance() on Windows: use os.replace() rather than os.rename(). Patch by Victor Stinner.
bpo-43842: Fix a race condition in the SMTP test of test_logging. Don 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.

bpo-35306: Avoid raising errors from pathlib.Path.exists() when passed an invalid filename.
bpo-38822: Fixed os.stat() failing on inaccessible directories with a trailing slash, rather than falling back to the parent directory metadata. This implicitly affected os.path.exists() and os.path.isdir().
bpo-26227: Fixed decoding of host names in socket.gethostbyaddr() and socket.gethostbyname_ex().
bpo-40432: Updated pegen regeneration script on Windows to find and use Python 3.8 or higher. Prior to this, pegen regeneration already required 3.8 or higher, but the script may have used lower versions of Python.
bpo-43745: Actually updates Windows release to OpenSSL 1.1.1k. Earlier releases were mislabelled and actually included 1.1.1i again.
bpo-43492: Upgrade Windows installer to use SQLite 3.35.5.

bpo-42119: Fix check for macOS SDK paths when building Python. Narrow search to match contents of SDKs, namely only files in /System/Library, /System/IOSSupport, and /usr other than /usr/local. Previously, anything under /System was assumed to be in an SDK which causes problems with the new file system layout in 10.15+ where user file systems may appear to be mounted under /System. Paths in /Library were also incorrectly treated as SDK locations.
bpo-44009: Provide ython3.x-intel64executable to allow reliably forcing macOS universal2 framework builds to run under Rosetta 2 Intel-64 emulation on Apple Silicon Macs. This can be useful for testing or when universal2 wheels are not yet available.
bpo-43492: Update macOS installer to use SQLite 3.35.4.

bpo-43655: IDLE dialog windows are now recognized as dialogs by window managers on macOS and X Window.

python39: updated to 3.9.3

Python 3.9.3 final

bpo-42988: 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.

Core and Builtins
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-43555: Report the column offset for SyntaxError for invalid line continuation characters. Patch by Pablo Galindo.
bpo-43517: Fix misdetection of circular imports when using from pkg.mod import attr, which caused false positives in non-trivial multi-threaded code.
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-42500: Improve handling of exceptions near recursion limit. Converts a number of Fatal Errors in RecursionErrors.

bpo-43433: xmlrpc.client.ServerProxy no longer ignores query and fragment in the URL of the server.
bpo-35930: Raising an exception raised in a utureinstance will create reference cycles.
bpo-43577: Fix deadlock when using ssl.SSLContext debug callback with ssl.SSLContext.sni_callback().
bpo-43521: ast.unparse can now render NaNs and empty sets.
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-43332: Improves the networking efficiency of http.client when using a proxy via set_tunnel(). Fewer small send calls are made during connection setup.
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 ׸hy 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 ield from <expr>works with any iterable, not just iterators.
bpo-36346: Update some deprecated unicode APIs which are documented as ill be removed in 4.0to .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 custom OpenSSL security level policy.
bpo-43288: Fix test_importlib to correctly skip Unicode file tests if the fileystem does not support them.

bpo-43631: Update macOS, Windows, and CI to OpenSSL 1.1.1k.
bpo-43617: Improve 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 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.

bpo-43155: PyCMethod_New() is now present in python3.lib.
Python 3.9.2 release candidate 1
Release date: 2021-02-16

bpo-42967: Fix web cache poisoning vulnerability by defaulting the query args separator to &, and allowing the user to choose a custom separator.
bpo-42938: Avoid static buffers when computing the repr of ctypes.c_double and ctypes.c_longdouble values.

Core and Builtins
bpo-42819: readline: Explicitly disable bracketed paste in the interactive interpreter, even if it set in the inputrc, is enabled by default (eg GNU Readline 8.1), or a user calls readline.read_init_file(). The Python REPL has not implemented bracketed paste support. Also, bracketed mode writes the "\x1b[?2004h" escape sequence into stdout which causes test failures in applications that don support it. It can still be explicitly enabled by calling readline.parse_and_bind("set enable-bracketed-paste on"). Patch by Dustin Rodrigues.
bpo-42806: Fix the column offsets for f-strings ast nodes surrounded by parentheses and for nodes that spawn multiple lines. Patch by Pablo Galindo.
bpo-40631: Fix regression where a single parenthesized starred expression was a valid assignment target.
bpo-32381: Fix encoding name when running a .pyc file on Windows: PyRun_SimpleFileExFlags() now uses the correct encoding to decode the filename.
bpo-42536: Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:

Previously, they could have become untracked by a prior garbage collection. Patch by Brandt Bucher.
bpo-42195: The __args__ of the parameterized generics for typing.Callable and are now consistent. The __args__ for are now flattened while typing.Callable have not changed. To allow this change, types.GenericAlias can now be subclassed and __class_getitem__ will now return a subclass of types.GenericAlias. Tests for typing were also updated to not subclass things like Callable[..., T] as that is not a valid base class. Finally, both types no longer validate their argtypes, in Callable[[argtypes], resulttype] to prepare for PEP 612. Patch by Ken Jin.

bpo-43102: The namedtuple __new__ method had its __builtins__ set to None instead of an actual dictionary. This created problems for introspection tools.
bpo-43108: Fixed a reference leak in the curses module. Patch by Pablo Galindo
bpo-42944: Fix random.Random.sample when counts argument is not None.
bpo-42931: Add randbytes() to random.__all__.
bpo-42780: Fix os.set_inheritable() for O_PATH file descriptors on Linux.
bpo-42851: remove __init_subclass__ support for Enum members
bpo-41748: Fix HTMLParser parsing rules for element attributes containing commas with spaces. Patch by Karl Dubost.
bpo-42759: Fixed equality comparison of tkinter.Variable and tkinter.font.Font. Objects which belong to different Tcl interpreters are now always different, even if they have the same name.
bpo-42756: Configure LMTP Unix-domain socket to use socket global default timeout when a timeout is not explicitly provided.
bpo-23328: Allow / character in username, password fields on _PROXY envars.
bpo-42655: subprocess extra_groups is now correctly passed into setgroups() system call.
bpo-42727: EnumMeta.__prepare__ now accepts **kwds to properly support __init_subclass__
bpo-42681: Fixed range checks for color and pair numbers in curses.
bpo-37961: Fix crash in tracemalloc.Traceback.__repr__() (regressed in Python 3.9).
bpo-42630: tkinter functions and constructors which need a default root window raise now RuntimeError with descriptive message instead of obscure AttributeError or NameError if it is not created yet or cannot be created automatically.
bpo-42644: logging.disable will now validate the types and value of its parameter. It also now accepts strings representing the levels (as does loging.setLevel) instead of only the numerical values.
bpo-36541: Fixed lib2to3.pgen2 to be able to parse PEP-570 positional only argument syntax.
bpo-42517: Enum: private names will raise a DeprecationWarning; in 3.10 they will become normal attributes
bpo-42678: Enum: call __init_subclass__ after members have been added
bpo-42532: Remove unexpected call of __bool__ when passing a spec_arg argument to a Mock.
bpo-42388: Fix subprocess.check_output( input=None) behavior when text=True to be consistent with that of the documentation and universal_newlines=True.
bpo-34463: Fixed discrepancy between traceback and the interpreter in formatting of SyntaxError with lineno not set (traceback was changed to match interpreter).
bpo-42375: subprocess module update for DragonFlyBSD support.
bpo-42384: Make pdb populate sys.path[0] exactly the same as regular python execution.
bpo-42383: Fix pdb: previously pdb would fail to restart the debugging target if it was specified using a relative path and the current directory changed.
bpo-42318: Fixed support of non-BMP characters in tkinter on macOS.
bpo-42163: Restore compatibility for uname_result around deepcopy and _replace.
bpo-39825: Windows: Change sysconfig.get_config_var('EXT_SUFFIX') to the expected full platform_tag.extension format. Previously it was hard-coded to .pyd, now it is compatible with distutils.sysconfig and will result in something like .cp38-win_amd64.pyd. This brings windows into conformance with the other platforms.
bpo-42059: typing.TypedDict types created using the alternative call-style syntax now correctly respect the total keyword argument when setting their __required_keys__ and __optional_keys__ class attributes.
bpo-39101: Fixed tests using IsolatedAsyncioTestCase from hanging on BaseExceptions.
bpo-42005: Fix CLI of cProfile and profile to catch BrokenPipeError.
bpo-41907: fix format() behavior for IntFlag
bpo-41889: Enum: fix regression involving inheriting a multiply-inherited enum
bpo-41891: Ensure asyncio.wait_for waits for task completion

bpo-40304: Fix doc for type(name, bases, dict). Patch by Boris Verkhovskiy and ric Araujo.
bpo-42811: Updated importlib.utils.resolve_name() doc to use __spec__.parent instead of __package__. (Thanks Yair Frid.)
bpo-17140: Add documentation for the multiprocessing.pool.ThreadPool class.

python39: updated to 3.9.1

Python 3.9.1 final

Core and Builtins

bpo-42576: types.GenericAlias will now raise a TypeError when attempting to initialize with a keyword argument. Previously, this would cause the interpreter to crash if the interpreter was compiled with debug symbols. This does not affect interpreters compiled for release. Patch by Ken Jin.


bpo-5054: CGIHTTPRequestHandler.run_cgi() HTTP_ACCEPT improperly parsed. Replace the special purpose getallmatchingheaders with generic get_all method and add relevant tests.
bpo-17735: inspect.findsource() now raises OSError instead of IndexError when co_lineno of a code object is greater than the file length. This can happen, for example, when a file is edited after it was imported.
bpo-42116: Fix handling of trailing comments by inspect.getsource().
bpo-42487: ChainMap.__iter__ no longer calls __getitem__ on underlying maps
bpo-42482: TracebackException no longer holds a reference to the exception traceback object. Consequently, instances of TracebackException for equivalent but non-equal exceptions now compare as equal.
bpo-42406: We fixed an issue in pickle.whichmodule in which importing multiprocessing could change the how pickle identifies which module an object belongs to, potentially breaking the unpickling of those objects.
bpo-34215: Clarify the error message for asyncio.IncompleteReadError when expected is None.
bpo-12800: Extracting a symlink from a tarball should succeed and overwrite the symlink if it already exists. The fix is to remove the existing file or symlink before extraction. Based on patch by Chris AtLee, Jeffrey Kintscher, and Senthil Kumaran.


bpo-41473: Reenable test_gdb on gdb 9.2 and newer: bug is fixed in gdb 10.1.
bpo-42553: Fix test_asyncio.test_call_later() race condition: don measure asyncio performance in the call_later() unit test. The test failed randomly on the CI.


bpo-41116: If no explicit macOS SDK was specified, should check for Tcl and TK frameworks in /Library/Frameworks; the previous commit inadvertently broke that test.
bpo-42504: Fix build on macOS Big Sur when MACOSX_DEPLOYMENT_TARGET=11


bpo-42508: Keep IDLE running on macOS. Remove obsolete workaround that prevented running files with shortcuts when using new universal2 installers built on macOS 11.
