Comment:
'''3.7.2 Final'''
{{{
Library
bpo-31715: Associate .mjs file extension with application/javascript
MIME Type.
Build
bpo-35499: make profile-opt no longer replaces CFLAGS_NODIST with
CFLAGS. It now adds profile-guided optimization (PGO) flags to
CFLAGS_NODIST: existing CFLAGS_NODIST flags are kept.
bpo-35257: Avoid leaking the linker flags from Link Time Optimizations
(LTO) into distutils when compiling C extensions.
C API
bpo-35259: Conditionally declare Py_FinalizeEx() (new in 3.6) based on
Py_LIMITED_API. Patch by Arthur Neufeld.
}}}
'''3.7.2 RELEASE CANDIDATE'''
{{{
Python 3.7.2 release candidate 1
Release date: 2018-12-11
Security
bpo-34812: The -I command line option (run Python in isolated mode) is
now also copied by the multiprocessing and distutils modules when spawning
child processes. Previously, only -E and -s options (enabled by -I) were
copied.
bpo-34791: The xml.sax and xml.dom.domreg no longer use environment
variables to override parser implementations when
sys.flags.ignore_environment is set by -E or -I arguments.
Core and Builtins
bpo-35444: Fixed error handling in pickling methods when fail to look
up builtin “getattr”.
bpo-35436: Fix various issues with memory allocation error handling.
Patch by Zackery Spytz.
bpo-35357: Internal attributes’ names of unittest.mock._Call and
unittest.mock.MagicProxy (name, parent & from_kall) are now prefixed with
_mock_ in order to prevent clashes with widely used object attributes.
Fixed minor typo in test function name.
bpo-35372: Fixed the code page decoder for input longer than 2 GiB
containing undecodable bytes.
bpo-35336: Fix PYTHONCOERCECLOCALE=1 environment variable: only coerce
the C locale if the LC_CTYPE locale is “C”.
bpo-33954: For str.format(), float.__format__() and
complex.__format__() methods for non-ASCII decimal point when using the
“n” formatter.
bpo-35269: Fix a possible segfault involving a newly-created
coroutine. Patch by Zackery Spytz.
bpo-35214: Fixed an out of bounds memory access when parsing a
truncated unicode escape sequence at the end of a string such as '\N'. It
would read one byte beyond the end of the memory allocation.
bpo-35214: The interpreter and extension modules have had annotations
added so that they work properly under clang’s Memory Sanitizer. A new
configure flag –with-memory-sanitizer has been added to make test builds
of this nature easier to perform.
bpo-35193: Fix an off by one error in the bytecode peephole optimizer
where it could read bytes beyond the end of bounds of an array when
removing unreachable code. This bug was present in every release of Python
3.6 and 3.7 until now.
bpo-29341: Clarify in the docstrings of os methods that path-like
objects are also accepted as input parameters.
bpo-35050: socket: Fix off-by-one bug in length check for AF_ALG name
and type.
bpo-34974: bytes and bytearray constructors no longer convert
unexpected exceptions (e.g. MemoryError and KeyboardInterrupt) to
TypeError.
bpo-34973: Fixed crash in bytes() when the list argument is mutated
while it is iterated.
bpo-34824: Fix a possible null pointer dereference in Modules/_ssl.c.
Patch by Zackery Spytz.
bpo-1621: Do not assume signed integer overflow behavior (C undefined
behavior) when performing set hash table resizing.
Library
bpo-35052: Fix xml.dom.minidom cloneNode() on a document with an
entity: pass the correct arguments to the user data handler of an entity.
bpo-35330: When a Mock instance was used to wrap an object, if
side_effect is used in one of the mocks of it methods, don’t call the
original implementation and return the result of using the side effect the
same way that it is done with return_value.
bpo-34172: Revert the fix for this issue previously released in 3.7.1
pending further investigation: Fix a reference issue inside
multiprocessing.Pool that caused the pool to remain alive if it was
deleted without being closed or terminated explicitly.
bpo-10496: posixpath.expanduser() now returns the input path unchanged
if the HOME environment variable is not set and the current user has no
home directory (if the current user identifier doesn’t exist in the
password database). This change fix the site module if the current user
doesn’t exist in the password database (if the user has no home
directory).
bpo-35310: Fix a bug in select.select() where, in some cases, the file
descriptor sequences were returned unmodified after a signal interruption,
even though the file descriptors might not be ready yet. select.select()
will now always return empty lists if a timeout has occurred. Patch by
Oran Avraham.
bpo-35380: Enable TCP_NODELAY on Windows for proactor asyncio event
loop.
bpo-35341: Add generic version of collections.OrderedDict to the
typing module. Patch by Ismo Toijala.

OpenLinux. Patch by Ville Skyttä.
bpo-35308: Fix regression in webbrowser where default browsers may be
preferred over browsers in the BROWSER environment variable.
bpo-28604: locale.localeconv() now sets temporarily the LC_CTYPE
locale to the LC_MONETARY locale if the two locales are different and
monetary strings are non-ASCII. This temporary change affects other
threads.
bpo-35277: Update ensurepip to install pip 18.1 and setuptools 40.6.2.
bpo-35226: Recursively check arguments when testing for equality of
unittest.mock.call objects and add note that tracking of parameters used
to create ancestors of mocks in mock_calls is not possible.
bpo-29564: The warnings module now suggests to enable tracemalloc if
the source is specified, the tracemalloc module is available, but
tracemalloc is not tracing memory allocations.
bpo-35189: Modify the following fnctl function to retry if interrupted
by a signal (EINTR): flock, lockf, fnctl
bpo-35062: Fix incorrect parsing of _io.IncrementalNewlineDecoder’s
translate argument.
bpo-35079: Improve difflib.SequenceManager.get_matching_blocks doc by
adding ‘non-overlapping’ and changing ‘!=’ to ‘<’.
bpo-35017: socketserver.BaseServer.serve_forever() now exits
immediately if it’s shutdown() method is called while it is polling for
new events.
bpo-31047: Fix ntpath.abspath regression where it didn’t remove a
trailing separator on Windows. Patch by Tim Graham.
bpo-34794: Fixed a leak in Tkinter when pass the Python wrapper around

RecursionError.
bpo-16965: The 2to3 execfile fixer now opens the file with mode 'rb'.
Patch by Zackery Spytz.
bpo-34966: pydoc now supports aliases not only to methods defined in
the end class, but also to inherited methods. The docstring is not
duplicated for aliases.
bpo-34941: Methods find(), findtext() and findall() of the Element
class in the xml.etree.ElementTree module are now able to find children
which are instances of Element subclasses.
bpo-34936: Fix TclError in tkinter.Spinbox.selection_element(). Patch
by Juliette Monsel.
bpo-34866: Adding max_num_fields to cgi.FieldStorage to make DOS
attacks harder by limiting the number of MiniFieldStorage objects created
by FieldStorage.
bpo-34022: The SOURCE_DATE_EPOCH environment variable no longer
overrides the value of the invalidation_mode argument to
py_compile.compile(), and determines its default value instead.
bpo-34738: ZIP files created by distutils will now include entries for
directories.
bpo-31177: Fix bug that prevented using reset_mock on mock instances
with deleted attributes
bpo-34536: Enum._missing_: raise ValueError if None returned and
TypeError if non-member is returned.
bpo-34604: Fix possible mojibake in the error message of pwd.getpwnam
and grp.getgrnam using string representation because of invisible
characters or trailing whitespaces. Patch by William Grzybowski.

anymore. Patch by Sergey Fedoseev.
bpo-34052: sqlite3.Connection.create_aggregate(),
sqlite3.Connection.create_function(), sqlite3.Connection.set_authorizer(),
sqlite3.Connection.set_progress_handler() methods raises TypeError when
unhashable objects are passed as callable. These methods now don’t pass
such objects to SQLite API. Previous behavior could lead to segfaults.
Patch by Sergey Fedoseev.
bpo-29877: compileall: import ProcessPoolExecutor only when needed,
preventing hangs on low resource platforms
bpo-22005: Implemented unpickling instances of datetime, date and time
pickled by Python 2. encoding='latin1' should be used for successful
decoding.
Documentation
bpo-35089: Remove mention of typing.io and typing.re. Their types
should be imported from typing directly.
bpo-35038: Fix the documentation about an unexisting f_restricted
attribute in the frame object. Patch by Stéphane Wirtel

bpo-32613: Update the faq/windows.html to use the py command from PEP
397 instead of python.
Tests
bpo-33725: test_multiprocessing_fork may crash on recent versions of
macOS. Until the issue is resolved, skip the test on macOS.
bpo-35352: Modify test_asyncio to use the certificate set from the
test directory.

test_localtime_daylight_true_dst_true() and
test_localtime_daylight_false_dst_true() with a specific timezone.
bpo-21263: After several reports that test_gdb does not work properly
on macOS and since gdb is not shipped by default anymore, test_gdb is now
skipped on macOS when LLVM Clang has been used to compile Python. Patch by
Lysandros Nikolaou
bpo-34279: regrtest issue a warning when no tests have been executed
in a particular test file. Also, a new final result state is issued if no

Build
bpo-35296: The Windows installer (MSI) now also install internal
header files (Include/internal/ subdirectory).
bpo-35351: When building Python with clang and LTO, LTO flags are no
longer passed into CFLAGS to build third-party C extensions through
distutils.
bpo-35139: Fix a compiler error when statically linking pyexpat in
Modules/Setup.
bpo-35011: Restores the use of pyexpatns.h to isolate our embedded

instead.
bpo-34532: Fixes exit code of list version arguments for py.exe.
bpo-32890: Fix usage of GetLastError() instead of errno in os.execve()
and os.truncate().
macOS
bpo-35402: Update macOS installer to use Tcl/Tk 8.6.9.1. [NOTE: This
change was reverted for the released python.org 3.7.2 macOS installers due
to regressions found in Tk 8.6.9.1. For now, the installers provide Tcl/Tk
8.6.8.]
bpo-35401: Update macOS installer to use OpenSSL 1.1.0j.
bpo-35025: Properly guard the use of the CLOCK_GETTIME et al. macros

Dock “prefer tabs always” setting disables some IDLE features. Menus are a
bit different than as described for Windows and Linux.
bpo-35202: Remove unused imports from lib/idlelib

is renamed from “IDLE – console differences” is renamed “Running user
code”. It mostly covers the implications of using custom sys.stdxxx
objects.
bpo-35097: Add IDLE doc subsection explaining editor windows. Topics
include opening, title and status bar, .py* extension, and running.
bpo-35093: Document the IDLE document viewer in the IDLE doc. Add a
paragraph in “Help and preferences”, “Help sources” subsection.
bpo-35088: Update idlelib.help.copy_string docstring. We now use git
and backporting instead of hg and forward merging.
bpo-35087: Update idlelib help files for the current doc build. The
main change is the elimination of chapter-section numbers.
Tools/Demos
bpo-34989: python-gdb.py now handles errors on computing the line
number of a Python frame.
C API
bpo-35322: Fix memory leak in PyUnicode_EncodeLocale() and
PyUnicode_EncodeFSDefault() on error handling.
bpo-35296: make install now also installs the internal API:
Include/internal/*.h header files.
