released shortly after the first developer preview of macOS 11 (Big Sur); there \ 
are other known issues with building and running on the developer preview. Big \ 
Sur is expected to be fully supported in a future bugfix release of Python 3.8.x \ 
and with 3.9.0.

Python 3.7.8 release candidate 1

Security
bpo-39073: Disallow CR or LF in email.headerregistry.Address arguments to guard \ 
against header injection attacks.
bpo-38576: Disallow control characters in hostnames in http.client, addressing \ 
CVE-2019-18348. Such potentially malicious header injection URLs now cause a \ 
InvalidURL to be raised.
bpo-39503: CVE-2020-8492: 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.

Core and Builtins
bpo-40663: Correctly generate annotations where parentheses are omitted but \ 
required (e.g: Type[(str, int, *other))].
bpo-40417: Fix imp module deprecation warning when PyImport_ReloadModule is \ 
called. Patch by Robert Rouhani.
bpo-20526: Fix PyThreadState_Clear(). PyThreadState.frame is a borrowed \ 
reference, not a strong reference: PyThreadState_Clear() must not call \ 
Py_CLEAR(tstate->frame).
bpo-38894: Fix a bug that was causing incomplete results when calling \ 
pathlib.Path.glob in the presence of symlinks that point to files where the user \ 
does not have read access. Patch by Pablo Galindo and Matt Wozniski.
bpo-39871: Fix a possible SystemError in math.{atan2,copysign,remainder}() when \ 
the first argument cannot be converted to a float. Patch by Zachary Spytz.

interpreter session on macOS.

Library
bpo-40448: ensurepip now disables the use of pip cache when installing the \ 
bundled versions of pip and setuptools. Patch by Krzysztof Konopko.
bpo-40807: Stop codeop._maybe_compile, used by code.InteractiveInterpreter (and \ 
IDLE). from from emitting each warning three times.
bpo-38488: Update ensurepip to install pip 20.1.1 and setuptools 47.1.0.
bpo-40767: webbrowser now properly finds the default browser in pure Wayland \ 
systems by checking the WAYLAND_DISPLAY environment variable. Patch contributed \ 
by Jérémy Attali.
bpo-30008: Fix ssl code to be compatible with OpenSSL 1.1.x builds that use \ 
no-deprecated and --api=1.1.0.
bpo-25872: linecache could crash with a KeyError when accessed from multiple \ 
threads. Fix by Michael Graczyk.
bpo-40515: The ssl and hashlib modules now actively check that OpenSSL is build \ 
with thread support. Python 3.7.0 made thread support mandatory and no longer \ 
works safely with a no-thread builds.
bpo-13097: ctypes now raises an ArgumentError when a callback is invoked with \ 
more than 1024 arguments.
bpo-40559: Fix possible memory leak in the C implementation of asyncio.Task.
bpo-40457: The ssl module now support OpenSSL builds without TLS 1.0 and 1.1 methods.
bpo-40459: platform.win32_ver() now produces correct ptype strings instead of \ 
empty strings.
bpo-40138: Fix the Windows implementation of os.waitpid() for exit code larger \ 
than INT_MAX >> 8. The exit status is now interpreted as an unsigned \ 
number.
bpo-39942: Set “__main__” as the default module name when “__name__” is \ 
missing in typing.TypeVar. Patch by Weipeng Hong.
bpo-40287: Fixed SpooledTemporaryFile.seek() to return the position.
bpo-40196: Fix a bug in the symtable module that was causing incorrectly report \ 
global variables as local. Patch by Pablo Galindo.
bpo-40126: Fixed reverting multiple patches in unittest.mock. Patcher’s \ 
__exit__() is now never called if its __enter__() is failed. Returning true from \ 
__exit__() silences now the exception.
bpo-40089: Fix threading._after_fork(): if fork was not called by a thread \ 
spawned by threading.Thread, threading._after_fork() now creates a _MainThread \ 
instance for _main_thread, instead of a _DummyThread instance.
bpo-39503: 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.
bpo-40014: Fix os.getgrouplist(): if getgrouplist() function fails because the \ 
group list is too small, retry with a larger group list. On failure, the glibc \ 
implementation of getgrouplist() sets ngroups to the total number of groups. For \ 
other implementations, double the group list size.
bpo-40025: Raise TypeError when _generate_next_value_ is defined after members. \ 
Patch by Ethan Onstott.
bpo-40016: In re docstring, clarify the relationship between inline and argument \ 
compile flags.
bpo-39652: The column name found in sqlite3.Cursor.description is now truncated \ 
on the first ‘[‘ only if the PARSE_COLNAMES option is set.
bpo-38662: The ensurepip module now invokes pip via the runpy module. Hence it \ 
is no longer tightly coupled with the internal API of the bundled pip version, \ 
allowing easier updates to a newer pip version both internally and for \ 
distributors.
bpo-39916: More reliable use of os.scandir() in Path.glob(). It no longer emits \ 
a ResourceWarning when interrupted.
bpo-39850: multiprocessing now supports abstract socket addresses (if abstract \ 
sockets are supported in the running platform). Patch by Pablo Galindo.

bpo-39040: Fix parsing of invalid mime headers parameters by collapsing \ 
whitespace between encoded words in a bare-quote-string.
bpo-35714: struct.error is now raised if there is a null character in a struct \ 
format string.
bpo-36541: lib2to3 now recognizes named assignment expressions (the walrus \ 
operator, :=)
bpo-29620: assertWarns() no longer raises a RuntimeException when accessing a \ 
module’s __warningregistry__ causes importation of a new module, or when a new \ 
module is imported in another thread. Patch by Kernc.

bpo-38387: Document PyDoc_STRVAR macro in the C-API reference.

Tests
bpo-40964: Disable remote imaplib tests, host cyrus.andrew.cmu.edu is blocking \ 
incoming connections.
bpo-40055: distutils.tests now saves/restores warnings filters to leave them \ 
unchanged. Importing tests imports docutils which imports pkg_resources which \ 
adds a warnings filter.
bpo-40436: test_gdb and test.pythoninfo now check gdb command exit code.
bpo-39932: Fix multiprocessing test_heap(): a new Heap object is now created for \ 
each test run.
bpo-40162: Update Travis CI configuration to OpenSSL 1.1.1f.
bpo-40146: Update OpenSSL to 1.1.1f in Azure Pipelines.
bpo-40019: test_gdb now skips tests if it detects that gdb failed to read debug \ 
information because the Python binary is optimized.
bpo-27807: test_site.test_startup_imports() is now skipped if a path of sys.path \ 
contains a .pth file.
bpo-39793: Use the same domain when testing make_msgid. Patch by Batuhan Taskaya.
bpo-1812: Fix newline handling in doctest.testfile when loading from a package \ 
whose loader has a get_data method. Patch by Peter Donis.
bpo-37957: test.regrtest now can receive a list of test patterns to ignore \ 
(using the -i/–ignore argument) or a file with a list of patterns to ignore \ 
(using the –ignore-file argument). Patch by Pablo Galindo.
bpo-38502: test.regrtest now uses process groups in the multiprocessing mode \ 
(-jN command line option) if process groups are available: if os.setsid() and \ 
os.killpg() functions are available.
bpo-37421: multiprocessing tests now stop the ForkServer instance if it’s \ 
running: close the “alive” file descriptor to ask the server to stop and \ 
then remove its UNIX address.
bpo-37421: multiprocessing tests now explicitly call _run_finalizers() to \ 
immediately remove temporary directories created by tests.

Build
bpo-40653: Move _dirnameW out of HAVE_SYMLINK to fix a potential compiling issue.
bpo-38360: Support single-argument form of macOS -isysroot flag.
bpo-40204: Pin Sphinx version to 2.3.1 in Doc/Makefile.
bpo-40158: Fix CPython MSBuild Properties in NuGet Package \ 
(build/native/python.props)

Windows
bpo-40164: Updates Windows OpenSSL to 1.1.1g
bpo-39631: Changes the registered MIME type for .py files on Windows to \ 
text/x-python instead of text/plain.

macOS
bpo-39580: Avoid opening Finder window if running installer from the command line.
bpo-40400: Update the macOS installer build scripts to build with Python 3.x and \ 
to build correctly on newer macOS systems with SIP.
bpo-40741: Update macOS installer to use SQLite 3.32.2.
bpo-38329: python.org macOS installers now update the Current version symlink of \ 
/Library/Frameworks/Python.framework/Versions for 3.9 installs. Previously, \ 
Current was only updated for Python 2.x installs. This should make it easier to \ 
embed Python 3 into other macOS applications.
bpo-40164: Update macOS installer builds to use OpenSSL 1.1.1g.

IDLE
bpo-39885: Make context menu Cut and Copy work again when right-clicking within \ 
a selection.
bpo-40723: Make test_idle pass when run after import.
bpo-27115: For ‘Go to Line’, use a Query box subclass with IDLE standard \ 
behavior and improved error checking.
bpo-39885: Since clicking to get an IDLE context menu moves the cursor, any text \ 
selection should be and now is cleared.
bpo-39852: Edit “Go to line” now clears any selection, preventing accidental \ 
deletion. It also updates Ln and Col on the status bar.
bpo-38439: Add a 256×256 pixel IDLE icon to support more modern environments. \ 
Created by Andrew Clover. Delete the unused macOS idle.icns icon file.
bpo-38689: IDLE will no longer freeze when inspect.signature fails when fetching \ 
a calltip.

Tools/Demos
bpo-40479: Update multissltest helper to test with latest OpenSSL 1.0.2, 1.1.0, \ 
1.1.1, and 3.0.0-alpha.
bpo-40179: Fixed translation of #elif in Argument Clinic.
bpo-40163: Fix multissltest tool. OpenSSL has changed download URL for old \ 
releases. The multissltest tool now tries to download from current and old \ 
download URLs.
bpo-36184: Port python-gdb.py to FreeBSD. python-gdb.py now checks for \ 
“take_gil” function name to check if a frame tries to acquire the GIL, \ 
instead of checking for “pthread_cond_timedwait” which is specific to Linux \ 
and can be a different condition than the GIL.
bpo-39889: Fixed unparse.py for extended slices containing a single element \ 
(e.g. a[i:j,]). Remove redundant tuples when index with a tuple (e.g. a[i, j]).
C API
bpo-39884: _PyMethodDef_RawFastCallDict() and _PyMethodDef_RawFastCallKeywords() \ 
now include the method name in the SystemError “bad call flags” error \ 
message to ease debug.
bpo-38643: PyNumber_ToBase() now raises a SystemError instead of crashing when \ 
called with invalid base.

Log message:
python37: updated to 3.7.7

Python 3.7.7 final

Library
bpo-13487: Avoid a possible “RuntimeError: dictionary changed size during \ 
iteration” from inspect.getmodule() when it tried to loop through sys.modules.
Documentation
bpo-17422: The language reference no longer restricts default class namespaces \ 
to dicts only.

Python 3.7.7 release candidate 1

Security
bpo-39401: Avoid unsafe load of api-ms-win-core-path-l1-1-0.dll at startup on \ 
Windows 7.
Core and Builtins
bpo-39776: Fix race condition where threads created by PyGILState_Ensure() could \ 
get a duplicate id.

This affects consumers of tstate->id like the contextvar caching machinery, \ 
which could return invalid cached objects under heavy thread load (observed in \ 
embedded scenarios).
bpo-39778: Fixed a crash due to incorrect handling of weak references in \ 
collections.OrderedDict classes. Patch by Pablo Galindo.
bpo-39382: Fix a use-after-free in the single inheritance path of issubclass(), \ 
when the __bases__ of an object has a single reference, and so does its first \ 
item. Patch by Yonatan Goldschmidt.
bpo-39606: Fix regression caused by fix for bpo-39386, that prevented calling \ 
aclose on an async generator that had already been closed or exhausted.
bpo-39510: Fix segfault in readinto() method on closed BufferedReader.
bpo-39453: Fixed a possible crash in list.__contains__() when a list is changed \ 
during comparing items. Patch by Dong-hee Na.
bpo-39427: Document all possibilities for the -X options in the command line \ 
help section. Patch by Pablo Galindo.
bpo-39421: Fix possible crashes when operating with the functions in the heapq \ 
module and custom comparison operators.
bpo-39386: Prevent double awaiting of async iterator.
bpo-38588: Fix possible crashes in dict and list when calling \ 
PyObject_RichCompareBool().
bpo-39031: When parsing an “elif” node, lineno and col_offset of the node \ 
now point to the “elif” keyword and not to its condition, making it \ 
consistent with the “if” node. Patch by Lysandros Nikolaou.
bpo-38610: Fix possible crashes in several list methods by holding strong \ 
references to list elements when calling PyObject_RichCompareBool().
Library
bpo-39794: Add –without-decimal-contextvar build option. This enables a \ 
thread-local rather than a coroutine local context.
bpo-39769: The compileall.compile_dir() function’s ddir parameter and the \ 
compileall command line flag -d no longer write the wrong pathname to the \ 
generated pyc file for submodules beneath the root of the directory tree being \ 
compiled. This fixes a regression introduced with Python 3.5.
bpo-30566: Fix IndexError when trying to decode an invalid string with punycode \ 
codec.
bpo-39649: Remove obsolete check for __args__ in bdb.Bdb.format_stack_entry.
bpo-27657: The original fix for bpo-27657, “Fix urlparse() with numeric \ 
paths” (GH-16839) included in 3.7.6, inadvertently introduced a behavior \ 
change that broke several third-party packages relying on the original undefined \ 
parsing behavior. The change is reverted in 3.7.7, restoring the behavior of \ 
3.7.5 and earlier releases.
bpo-21016: The pydoc and trace modules now use the sysconfig module to get the \ 
path to the Python standard library, to support uncommon installation path like \ 
/usr/lib64/python3.9/ on Fedora. Patch by Jan Matějek.
bpo-39548: Fix handling of header in urllib.request.AbstractDigestAuthHandler \ 
when the optional qop parameter is not present.
bpo-39450: Striped whitespace from docstring before returning it from \ 
unittest.case.shortDescription().
bpo-39493: Mark typing.IO.closed as a property
bpo-39485: Fix a bug in unittest.mock.create_autospec() that would complain \ 
about the wrong number of arguments for custom descriptors defined in an \ 
extension module returning functions.
bpo-39430: Fixed race condition in lazy imports in tarfile.
bpo-39389: Write accurate compression level metadata in gzip archives, rather \ 
than always signaling maximum compression.
bpo-39274: bool(fraction.Fraction) now returns a boolean even if (numerator != \ 
0) does not return a boolean (ex: numpy number).
bpo-39242: Updated the Gmane domain from news.gmane.org to news.gmane.io which \ 
is used for examples of NNTP news reader server and nntplib tests.
bpo-39152: Fix ttk.Scale.configure([name]) to return configuration tuple for \ 
name or all options. Giovanni Lombardo contributed part of the patch.
bpo-39198: If an exception were to be thrown in Logger.isEnabledFor (say, by \ 
asyncio timeouts or stopit) , the logging global lock may not be released \ 
appropriately, resulting in deadlock. This change wraps that block of code with \ 
try...finally to ensure the lock is released.
bpo-39191: Perform a check for running loop before starting a new task in \ 
loop.run_until_complete() to fail fast; it prevents the side effect of new task \ 
spawning before exception raising.
bpo-38871: Correctly parenthesize filter-based statements that contain lambda \ 
expressions in mod:lib2to3. Patch by Dong-hee Na.
bpo-39142: A change was made to logging.config.dictConfig to avoid converting \ 
instances of named tuples to ConvertingTuple. It’s assumed that named tuples \ 
are too specialised to be treated like ordinary tuples; if a user of named \ 
tuples requires ConvertingTuple functionality, they will have to implement that \ 
themselves in their named tuple class.
bpo-38971: Open issue in the BPO indicated a desire to make the implementation \ 
of codecs.open() at parity with io.open(), which implements a try/except to \ 
assure file stream gets closed before an exception is raised.
bpo-39057: urllib.request.proxy_bypass_environment() now ignores leading dots \ 
and no longer ignores a trailing newline.
bpo-39056: Fixed handling invalid warning category in the -W option. No longer \ 
import the re module if it is not needed.
bpo-39055: base64.b64decode() with validate=True raises now a binascii.Error if \ 
the input ends with a single \n.
bpo-38878: Fixed __subclasshook__ of os.PathLike to return a correct result upon \ 
inheritence. Patch by Bar Harel.
bpo-35182: Fixed Popen.communicate() subsequent call crash when the child \ 
process has already closed any piped standard stream, but still continues to be \ 
running. Patch by Andriy Maletsky.
bpo-38473: Use signature from inner mock for autospecced methods attached with \ 
unittest.mock.attach_mock(). Patch by Karthikeyan Singaravelan.
bpo-38293: Add copy.copy() and copy.deepcopy() support to property() objects.
bpo-37953: In typing, improved the __hash__ and __eq__ methods for ForwardReferences.
bpo-36406: Handle namespace packages in doctest. Patch by Karthikeyan Singaravelan.
Documentation
bpo-13790: Change ‘string’ to ‘specification’ in format doc.
bpo-39530: Fix misleading documentation about mixed-type numeric comparisons.
bpo-17422: The language reference now specifies restrictions on class \ 
namespaces. Adapted from a patch by Ethan Furman.
bpo-39654: In pyclbr doc, update ‘class’ to ‘module’ where appropriate \ 
and add readmodule comment. Patch by Hakan Çelik.
bpo-39392: Explain that when filling with turtle, overlap regions may be left \ 
unfilled.
bpo-39381: Mention in docs that asyncio.get_event_loop() implicitly creates new \ 
event loop only if called from the main thread.
bpo-38918: Add an entry for __module__ in the “function” & “method” \ 
sections of the inspect docs types and members table
bpo-3530: In the ast module documentation, fix a misleading NodeTransformer \ 
example and add advice on when to use the fix_missing_locations function.
Tests
bpo-38546: Fix test_ressources_gced_in_workers() of test_concurrent_futures: \ 
explicitly stop the manager to prevent leaking a child process running in the \ 
background after the test completes.
Build
bpo-39144: The ctags and etags build targets both include Modules/_ctypes and \ 
Python standard library source files.
Windows
bpo-38597: distutils will no longer statically link vcruntime140.dll when a \ 
redistributable version is unavailable. All future releases of CPython will \ 
include a copy of this DLL to ensure distributed extensions can continue to \ 
load.
bpo-38380: Update Windows builds to use SQLite 3.31.1
bpo-39439: Reduce overhead when using multiprocessing in a Windows virtual \ 
environment
bpo-39185: The build.bat script has additional options for very-quiet output \ 
(-q) and very-verbose output (-vv)
macOS
bpo-38380: Update macOS builds to use SQLite 3.31.1
IDLE
bpo-39781: Selecting code context lines no longer causes a jump.
bpo-39663: Add tests for pyparse find_good_parse_start().
bpo-39600: In the font configuration window, remove duplicated font names.
bpo-30780: Add remaining configdialog tests for buttons and highlights and keys tabs.
bpo-39388: IDLE Settings Cancel button now cancels pending changes
bpo-39050: Make IDLE Settings dialog Help button work again.
bpo-34118: Tag memoryview, range, and tuple as classes, the same as list, \ 
etcetera, in the library manual built-in functions list.
bpo-38792: Close an IDLE shell calltip if a KeyboardInterrupt or shell restart \ 
occurs. Patch by Zackery Spytz.
bpo-32989: Add tests for editor newline_and_indent_event method. Remove dead \ 
code from pyparse find_good_parse_start method.

default context or if a cert_file is passed to HTTPSConnection.
bpo-37437: Update vendorized expat version to 2.2.7.
bpo-37428: SSLContext.post_handshake_auth = True no longer sets \ 
SSL_VERIFY_POST_HANDSHAKE verify flag for client connections. Although the \ 
option is documented as ignored for clients, OpenSSL implicitly enables cert \ 
chain validation when the flag is set.

resource.setrlimit to increase the process stack size limit at runtime. The \ 
runtime change is no longer needed since the interpreter is being built with a \ 
larger default stack size.
