- bpo-34812: The :option:`-I` command line option (run Python in isolated
|
|
|
mode) is now also copied by the :mod:`multiprocessing` and
|
|
|

|
|
|
|
|
- bpo-35214: The interpreter and extension modules have had annotations
|
|

|
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
|

|
|
|
mutated while it is iterated.

Documentation
|
|
|
-------------
|
|
|
|
|
|
- bpo-34790: Document how passing coroutines to asyncio.wait() can be
|
|
|
confusing.
|
|
|
|
|
|

|
|
|
support membership tests.

|
|
|
compiled with Python 3.6 or earlier.
|
|
|
|
|
|
- bpo-34587: test_socket: Remove RDSTest.testCongestion(). The test tries to
|
|
|
fill the receiver's socket buffer and expects an error. But the RDS
|
|
|
protocol doesn't require that. Moreover, the Linux implementation of RDS
|
|
|
expects that the producer of the messages reduces its rate, it's not the
|
|
|
role of the receiver to trigger an error. The test fails on Fedora 28 by
|
|
|
design, so just remove it.
|
|
|
|
|
|
- bpo-34661: Fix test_shutil if unzip doesn't support -t.
|
|
|
|
|
|

|
|
|
contents between test cases.
|
|
|
|
|
|
- bpo-34594: Fix usage of hardcoded ``errno`` values in the tests.

|
|
|
|

|
|
|
provide 'sockname', so skip calls to transport.get_extra_info('sockname')
|
|
|
|
|
|
- bpo-34391: Fix ftplib test for TLS 1.3 by reading from data socket.
|
|

|
|
|

|
|

|
|
|
--huntrleaks/-R was used. Exit with error in case that invalid parameters
|
|
|
are specified to --huntrleaks/-R (at least one warmup run and one
|
|
|
repetition must be used).
|
|
|
|
|
|
- bpo-32663: Making sure the `SMTPUTF8SimTests` class of tests gets run in
|
|
|
test_smtplib.py.

- bpo-34225: Ensure INCLUDE and LIB directories do not end with a backslash.
|
|
|
|
|
|
- bpo-34006: Revert line length limit for Windows help docs. The line-length
|
|
|
limit is not needed because the pages appear in a separate app rather than
|
|
|
on a browser tab. It can also interact badly with the DPI setting.
|
|
|
|
|
|
- bpo-31546: Restore running PyOS_InputHook while waiting for user input at
|
|
|
the prompt. The restores integration of interactive GUI windows (such as

|
|
|
- bpo-34370: Have macOS 10.9+ installer builds for 3.7.1rc and 3.6.7rc use a
|
|
|
development snapshot of Tk 8.6 (post-8.6.8) to mitigate certain scroller
|
|
|
issues seen with IDLE and tkinter apps.
|
|
|
|
|
|
- bpo-34405: Update to OpenSSL 1.1.0i for macOS installer builds.
|
|
|
|
|
|
- bpo-33635: In macOS stat on some file descriptors (/dev/fd/3 f.e) will
|
|
|
result in bad file descriptor OSError. Guard against this exception was
|
|
|
added in is_dir, is_file and similar methods. DirEntry.is_dir can also
|
|
|
throw this exception so _RecursiveWildcardSelector._iterate_directories
|
|
|
was also extended with the same error ignoring pattern.
|
|
|
|
|
|
- bpo-31903: In :mod:`_scproxy`, drop the GIL when calling into

|
performance degradation and to clean up the history without losing it.
|
|
|
Squeezed outputs may be copied, viewed in a separate window, and
|
|
|
"unsqueezed".
|
|
|
|
|
|
- bpo-34047: Fixed mousewheel scrolling direction on macOS.
|
|
|
|
|
|
- bpo-34275: Make IDLE calltips always visible on Mac. Some MacOS-tk
|
|
|
combinations need .update_idletasks(). Patch by Kevin Walzer.
|
|
|
|
|
|
- bpo-34120: Fix unresponsiveness after closing certain windows and dialogs.
|
|
|
|
|
|
- bpo-33975: Avoid small type when running htests. Since part of the purpose
|
|
|
of human-viewed tests is to determine that widgets look right, it is
|
|
|
important that they look the same for testing as when running IDLE.
|
|
|
|
|
|
- bpo-33905: Add test for idlelib.stackview.StackBrowser.
|
|
|
|

- bpo-33906: Rename idlelib.windows as window Match Window on the main menu
|
|
|
and remove last plural module name.
|
|
|
|
|
|
- bpo-33917: Fix and document idlelib/idle_test/template.py. The revised
|
|
|
file compiles, runs, and tests OK. idle_test/README.txt explains how to
|
|
|
use it to create new IDLE test files.
|
|
|
|
|
|
- bpo-33904: IDLE: In rstrip, rename class RstripExtension as Rstrip
|
|
|
|
|
|
- bpo-33907: For consistency and clarity, rename an IDLE module and classes.
|
|
|
Module calltips and its class CallTips are now calltip and Calltip. In
|
|
|
module calltip_w, class CallTip is now CalltipWindow.

|
|
|
|
|
- bpo-33839: IDLE: refactor ToolTip and CallTip and add documentation and
|
|
|
tests
|
|
|
|

|
|
|
|
|
- bpo-23927: Fixed :exc:`SystemError` in
|
|
|
:c:func:`PyArg_ParseTupleAndKeywords` when the ``w*`` format unit is used
|
|
|
for optional parameter.
|
|
|
|
|

|
-----
|
|
|
|
|
|
- bpo-5755: Move ``-Wstrict-prototypes`` option to ``CFLAGS_NODIST`` from
|
|
|
``OPT``. This option emitted annoying warnings when building extension
|
|
|
modules written in C++.
|

|
|
Windows
|
|
|
-------
|
|
|

|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-33656: On Windows, add API call saying that tk scales for DPI. On
|
|
|
Windows 8.1+ or 10, with DPI compatibility properties of the Python binary
|
|

unchanged, and a monitor resolution greater than 96 DPI, this should make
|
|

partial lines at the top of the editor box. The change also applies to
|
|
|
the shell and grep output windows, but not to read-only text views.
|
|
|
|
|
|
- bpo-33679: Enable theme-specific color configuration for Code Context. Use
|
|
|
the Highlights tab to see the setting for built-in themes or add settings
|
|
|
to custom themes.
|
|
|
|
|
|
- bpo-33642: Display up to maxlines non-blank lines for Code Context. If
|

|
|
instead.

- bpo-32684: Fix gather to propagate cancellation of itself even with
|
|
|
return_exceptions.
|
|

- bpo-33654: Support protocol type switching in SSLTransport.set_protocol().
|
|
|
|
|
|
- bpo-33674: Pause the transport as early as possible to further reduce the
|
|

risk of data_received() being called before connection_made().
|
|
|
|
|
|
- bpo-33674: Fix a race condition in SSLProtocol.connection_made() of
|
|
|
asyncio.sslproto: start immediately the handshake instead of using
|
|
|
call_soon(). Previously, data_received() could be called before the
|
|
|
handshake started, causing the handshake to hang or fail.
|
|
|
|
|
|
- bpo-31647: Fixed bug where calling write_eof() on a
|
|
|
_SelectorSocketTransport after it's already closed raises AttributeError.

|
|
|

|
|
|
- bpo-33570: Change TLS 1.3 cipher suite settings for compatibility with

|
|
enabled by default.
|
|
|

|
|
- bpo-28556: Do not simplify arguments to `typing.Union`. Now

|
|
|
Such simplification previously caused several bugs and limited
|
|
|
possibilities for introspection.
|
|
|
|
|
|
- bpo-33540: Add a new ``block_on_close`` class attribute to
|
|
|
``ForkingMixIn`` and ``ThreadingMixIn`` classes of :mod:`socketserver`.

Brown.
|
|
|
|
|
|
- bpo-33495: Change dataclasses.Fields repr to use the repr of each of its
|
|

|
actually represents. This is especially true for the 'type' member.
|
|
|
|
|
|
- bpo-33453: Fix dataclasses to work if using literal string type
|
|
|
annotations or if using PEP 563 "Postponed Evaluation of Annotations".

switch. (The regression was introduced in 3.7.0b3 by the resolution of
|
|
|
:issue:`33053`)
|
|
|
|
|
|
This fix also changed pydoc to add ``os.getcwd()`` to :data:`sys.path`

|
|

|
|
|
__set_name__ special method on the class, not the instance, of the default

|
|
value.
|
|
|
|
|
|
- bpo-33097: Raise RuntimeError when ``executor.submit`` is called during
|

|
interpreter shutdown.

*Release date: 2018-03-29*
|
|
|
|
|
|
Security
|
|
|
--------
|
|
|
|
|
|
- bpo-33136: Harden ssl module against LibreSSL CVE-2018-8970.
|
|
|
X509_VERIFY_PARAM_set1_host() is called with an explicit namelen. A new
|
|
|
test ensures that NULL bytes are not allowed.
|
|
|
|
|
|

|
|
|
|
|
|

backtracking. These regexes formed potential DOS vectors (REDOS). They
|
|
|
have been refactored. This resolves CVE-2018-1060 and CVE-2018-1061. Patch
|
|
|
by Jamie Davis.
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-33053: When using the -m switch, sys.path[0] is now explicitly
|
|
|
expanded as the *starting* working directory, rather than being left as
|
|
|
the empty path (which allows imports from the current working directory at
|
|
|
the time of the import)
|
|
|
|
|
|
- bpo-33018: Improve consistency of errors raised by ``issubclass()`` when
|
|
|
called with a non-class and an abstract base class as the first and second
|
|
|
arguments, respectively. Patch by Josh Bronson.
|
|
|
|
|
|
- bpo-33041: Fixed jumping when the function contains an ``async for`` loop.
|
|
|
|
|
|
- bpo-33026: Fixed jumping out of "with" block by setting f_lineno.
|
|
|
|
|
|
- bpo-33005: Fix a crash on fork when using a custom memory allocator (ex:
|
|
|
using PYTHONMALLOC env var). _PyGILState_Reinit() and
|
|
|
_PyInterpreterState_Enable() now use the default RAW memory allocator to
|
|
|
allocate a new interpreters mutex on fork.
|
|
|
|
|
|
- bpo-17288: Prevent jumps from 'return' and 'exception' trace events.

Library
|
|
|
-------
|
|
|
|
|
|
- bpo-33141: Have Field objects pass through __set_name__ to their default
|
|
|
values, if they have their own __set_name__.
|
|
|
|
|
|
- bpo-33096: Allow ttk.Treeview.insert to insert iid that has a false
|
|
|
boolean value. Note iid=0 and iid=False would be same. Patch by Garvit
|
|
|
Khatri.
|
|
|
|
|
|
- bpo-32873: Treat type variables and special typing forms as immutable by
|
|
|
copy and pickle. This fixes several minor issues and inconsistencies, and
|
|
|
improves backwards compatibility with Python 3.6.
|
|
|
|
|
|
- bpo-33134: When computing dataclass's __hash__, use the lookup table to
|
|
|
contain the function which returns the __hash__ value. This is an
|
|
|
improvement over looking up a string, and then testing that string to see
|
|
|
what to do.
|
|
|
|
|
|
- bpo-33127: The ssl module now compiles with LibreSSL 2.7.1.
|
|
|
|
|
|
- bpo-32505: Raise TypeError if a member variable of a dataclass is of type
|
|
|
Field, but doesn't have a type annotation.
|
|
|
|
|
|
- bpo-33078: Fix the failure on OSX caused by the tests relying on
|
|
|
sem_getvalue
|
|
|
|
|
|
- bpo-33116: Add 'Field' to dataclasses.__all__.
|
|
|
|
|
|
- bpo-32896: Fix an error where subclassing a dataclass with a field that
|
|
|
uses a default_factory would generate an incorrect class.
|
|
|
|
|
|
- bpo-33100: Dataclasses: If a field has a default value that's a
|
|
|
MemberDescriptorType, then it's from that field being in __slots__, not an
|
|
|
actual default value.
|
|
|
|
|
|
- bpo-32953: If a non-dataclass inherits from a frozen dataclass, allow
|
|
|
attributes to be added to the derived class. Only attributes from the
|
|
|
frozen dataclass cannot be assigned to. Require all dataclasses in a
|
|
|
hierarchy to be either all frozen or all non-frozen.
|
|
|
|
|
|
- bpo-33061: Add missing ``NoReturn`` to ``__all__`` in typing.py
|
|
|
|
|
|
- bpo-33078: Fix the size handling in multiprocessing.Queue when a pickling
|
|
|
error occurs.
|
|
|
|
|
|
- bpo-33064: lib2to3 now properly supports trailing commas after ``*args``
|
|
|
and ``**kwargs`` in function signatures.
|
|
|
|
|
|
- bpo-33056: FIX properly close leaking fds in
|
|
|
concurrent.futures.ProcessPoolExecutor.
|
|
|
|
|
|
- bpo-33021: Release the GIL during fstat() calls, avoiding hang of all
|
|
|
threads when calling mmap.mmap(), os.urandom(), and random.seed(). Patch
|
|
|
by Nir Soffer.
|
|
|
|
|
|
- bpo-31804: Avoid failing in multiprocessing.Process if the standard
|
|
|
streams are closed or None at exit.
|
|
|
|
|
|
- bpo-33037: Skip sending/receiving data after SSL transport closing.
|
|
|
|
|
|
- bpo-27683: Fix a regression in :mod:`ipaddress` that result of
|
|
|
:meth:`hosts` is empty when the network is constructed by a tuple
|
|
|
containing an integer mask and only 1 bit left for addresses.
|
|
|
|
|
|
- bpo-32999: Fix C implementation of ``ABC.__subclasscheck__(cls,
|
|
|
subclass)`` crashed when ``subclass`` is not a type object.
|
|
|
|
|
|
- bpo-33009: Fix inspect.signature() for single-parameter partialmethods.
|
|
|
|
|
|
- bpo-32969: Expose several missing constants in zlib and fix corresponding
|
|
|
documentation.
|
|
|
|
|
|
- bpo-32056: Improved exceptions raised for invalid number of channels and
|
|
|
sample width when read an audio file in modules :mod:`aifc`, :mod:`wave`
|
|
|
and :mod:`sunau`.
|
|
|
|
|
|
- bpo-32844: Fix wrong redirection of a low descriptor (0 or 1) to stderr in
|
|
|
subprocess if another low descriptor is closed.
|
|
|
|
|
|
- bpo-32857: In :mod:`tkinter`, ``after_cancel(None)`` now raises a
|
|
|
:exc:`ValueError` instead of canceling the first scheduled function.
|
|
|
Patch by Cheryl Sabella.
|
|
|
|
|
|
- bpo-31639: http.server now exposes a ThreadedHTTPServer class and uses it
|
|
|
when the module is run with ``-m`` to cope with web browsers pre-opening
|
|
|
sockets.
|
|
|
|
|
|
- bpo-27645: :class:`sqlite3.Connection` now exposes a
|
|
|
:class:`~sqlite3.Connection.backup` method, if the underlying SQLite
|
|
|
library is at version 3.6.11 or higher. Patch by Lele Gaifax.
|
|
|
|
|
|
Documentation
|
|
|
-------------
|
|
|
|
|
|
- bpo-33126: Document PyBuffer_ToContiguous().
|
|
|
|
|
|
- bpo-27212: Modify documentation for the :func:`islice` recipe to consume
|
|
|
initial values up to the start index.
|
|
|
|
|
|
- bpo-28247: Update :mod:`zipapp` documentation to describe how to make
|
|
|
standalone applications.
|
|
|
|
|
|
- bpo-18802: Documentation changes for ipaddress. Patch by Jon Foster and
|
|
|
Berker Peksag.
|
|
|
|
|
|
- bpo-27428: Update documentation to clarify that ``WindowsRegistryFinder``
|
|
|
implements ``MetaPathFinder``. (Patch by Himanshu Lakhara)
|
|
|
|
|
|
Tests
|
|
|
-----
|
|
|
|
|
|
- bpo-32872: Avoid regrtest compatibility issue with namespace packages.
|
|
|
|
|
|
- bpo-32517: Fix failing ``test_asyncio`` on macOS 10.12.2+ due to transport
|
|
|
of ``KqueueSelector`` loop was not being closed.
|
|
|
|
|
|
- bpo-19417: Add test_bdb.py.
|
|
|
|
|
|
Build
|
|
|
-----
|
|
|
|
|
|
- bpo-33163: Upgrade pip to 9.0.3 and setuptools to v39.0.1.
|
|
|
|
|
|
Windows
|
|
|
-------
|
|
|
|
|
|
- bpo-33016: Fix potential use of uninitialized memory in
|
|
|
nt._getfinalpathname
|
|
|
|
|
|
- bpo-32903: Fix a memory leak in os.chdir() on Windows if the current
|
|
|
directory is set to a UNC path.
|
|
|
|
|
|
macOS
|
|
|
-----
|
|
|
|
|
|
- bpo-32726: Build and link with private copy of Tcl/Tk 8.6 for the macOS
|
|
|
10.6+ installer. The 10.9+ installer variant already does this. This
|
|
|
means that the Python 3.7 provided by the python.org macOS installers no
|
|
|
longer need or use any external versions of Tcl/Tk, either system-provided
|
|
|
or user-installed, such as ActiveTcl.
|
|
|
|
|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-32984: Set ``__file__`` while running a startup file. Like Python,
|
|
|
IDLE optionally runs one startup file in the Shell window before
|
|
|
presenting the first interactive input prompt. For IDLE, ``-s`` runs a
|
|
|
file named in environmental variable :envvar:`IDLESTARTUP` or
|
|
|
:envvar:`PYTHONSTARTUP`; ``-r file`` runs ``file``. Python sets
|
|
|
``__file__`` to the startup file name before running the file and unsets
|
|
|
it before the first prompt. IDLE now does the same when run normally,
|
|
|
without the ``-n`` option.
|
|
|
|
|
|
- bpo-32940: Simplify and rename StringTranslatePseudoMapping in pyparse.
|
|
|
|
|
|
Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-32885: Add an ``-n`` flag for ``Tools/scripts/pathfix.py`` to disable
|
|
|
automatic backup creation (files with ``~`` suffix).
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-33042: Embedding applications may once again call
|
|
|
PySys_ResetWarnOptions, PySys_AddWarnOption, and PySys_AddXOption prior to
|
|
|
calling Py_Initialize.
|
|
|
|
|
|
- bpo-32374: Document that m_traverse for multi-phase initialized modules
|
|
|
can be called with m_state=NULL, and add a sanity check
|
|
|
|
|
|
|
|
|

|
|
|
|
*Release date: 2018-02-27*
|
|
|
|
|
|
Security
|
|
|
--------
|
|
|
|
|
|
- bpo-28414: The ssl module now allows users to perform their own IDN
|
|
|
en/decoding when using SNI.
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-32889: Update Valgrind suppression list to account for the rename of
|
|
|
``Py_ADDRESS_IN_RANG`` to ``address_in_range``.
|
|
|
|
|
|
- bpo-31356: Remove the new API added in bpo-31356 (gc.ensure_disabled()
|
|
|
context manager).
|
|
|
|
|
|
- bpo-32305: For namespace packages, ensure that both ``__file__`` and
|
|
|
``__spec__.origin`` are set to None.
|
|
|
|
|
|
- bpo-32303: Make sure ``__spec__.loader`` matches ``__loader__`` for
|
|
|
namespace packages.
|
|
|
|
|
|
- bpo-32711: Fix the warning messages for Python/ast_unparse.c. Patch by
|
|
|
Stéphane Wirtel
|
|
|
|
|
|
- bpo-32583: Fix possible crashing in builtin Unicode decoders caused by
|
|
|
write out-of-bound errors when using customized decode error handlers.
|
|
|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-32960: For dataclasses, disallow inheriting frozen from non-frozen
|
|
|
classes, and also disallow inheriting non-frozen from frozen classes. This
|
|
|
restriction will be relaxed at a future date.
|
|
|
|
|
|
- bpo-32713: Fixed tarfile.itn handling of out-of-bounds float values. Patch
|
|
|
by Joffrey Fuhrer.
|
|
|
|
|
|
- bpo-32951: Direct instantiation of SSLSocket and SSLObject objects is now
|
|
|
prohibited. The constructors were never documented, tested, or designed as
|
|
|
public constructors. Users were suppose to use ssl.wrap_socket() or
|
|
|
SSLContext.
|
|
|
|
|
|
- bpo-32929: Remove the tri-state parameter "hash", and add the boolean
|
|
|
"unsafe_hash". If unsafe_hash is True, add a __hash__ function, but if a
|
|
|
__hash__ exists, raise TypeError. If unsafe_hash is False, add a __hash__
|
|
|
based on the values of eq= and frozen=. The unsafe_hash=False behavior is
|
|
|
the same as the old hash=None behavior. unsafe_hash=False is the default,
|
|
|
just as hash=None used to be.
|
|
|
|
|
|
- bpo-32947: Add OP_ENABLE_MIDDLEBOX_COMPAT and test workaround for TLSv1.3
|
|
|
for future compatibility with OpenSSL 1.1.1.
|
|
|
|
|
|
- bpo-30622: The ssl module now detects missing NPN support in LibreSSL.
|
|
|
|
|
|
- bpo-32922: dbm.open() now encodes filename with the filesystem encoding
|
|
|
rather than default encoding.
|
|
|
|
|
|
- bpo-32859: In ``os.dup2``, don't check every call whether the ``dup3``
|
|
|
syscall exists or not.
|
|
|
|
|
|
- bpo-32556: nt._getfinalpathname, nt._getvolumepathname and
|
|
|
nt._getdiskusage now correctly convert from bytes.
|
|
|
|
|
|
- bpo-25988: Emit a :exc:`DeprecationWarning` when using or importing an ABC
|
|
|
directly from :mod:`collections` rather than from :mod:`collections.abc`.
|
|
|
|
|
|
- bpo-21060: Rewrite confusing message from setup.py upload from "No dist
|
|
|
file created in earlier command" to the more helpful "Must create and
|
|
|
upload files in one command".
|
|
|
|
|
|
- bpo-32852: Make sure sys.argv remains as a list when running trace.
|
|
|
|
|
|
- bpo-31333: ``_abc`` module is added. It is a speedup module with C
|
|
|
implementations for various functions and methods in ``abc``. Creating an
|
|
|
ABC subclass and calling ``isinstance`` or ``issubclass`` with an ABC
|
|
|
subclass are up to 1.5x faster. In addition, this makes Python start-up up
|
|
|
to 10% faster.
|
|
|
|
|
|
Note that the new implementation hides internal registry and caches,
|
|
|
previously accessible via private attributes ``_abc_registry``,
|
|
|
``_abc_cache``, and ``_abc_negative_cache``. There are three debugging
|
|
|
helper methods that can be used instead ``_dump_registry``,
|
|
|
``_abc_registry_clear``, and ``_abc_caches_clear``.
|
|
|
|
|
|
- bpo-32841: Fixed `asyncio.Condition` issue which silently ignored
|
|
|
cancellation after notifying and cancelling a conditional lock. Patch by
|
|
|
Bar Harel.
|
|
|
|
|
|
- bpo-32819: ssl.match_hostname() has been simplified and no longer depends
|
|
|
on re and ipaddress module for wildcard and IP addresses. Error reporting
|
|
|
for invalid wildcards has been improved.
|
|
|
|
|
|
- bpo-32394: socket: Remove
|
|
|
TCP_FASTOPEN,TCP_KEEPCNT,TCP_KEEPIDLE,TCP_KEEPINTVL flags on older version
|
|
|
Windows during run-time.
|
|
|
|
|
|
- bpo-31787: Fixed refleaks of ``__init__()`` methods in various modules.
|
|
|
(Contributed by Oren Milman)
|
|
|
|
|
|
- bpo-30157: Fixed guessing quote and delimiter in csv.Sniffer.sniff() when
|
|
|
only the last field is quoted. Patch by Jake Davis.
|
|
|
|
|
|
- bpo-32792: collections.ChainMap() preserves the order of the underlying
|
|
|
mappings.
|
|
|
|
|
|
- bpo-32775: :func:`fnmatch.translate()` no longer produces patterns which
|
|
|
contain set operations. Sets starting with '[' or containing '--', '&&',
|
|
|
'~~' or '||' will be interpreted differently in regular expressions in
|
|
|
future versions. Currently they emit warnings. fnmatch.translate() now
|
|
|
avoids producing patterns containing such sets by accident.
|
|
|
|
|
|
- bpo-32622: Implement native fast sendfile for Windows proactor event loop.
|
|
|
|
|
|
- bpo-32777: Fix a rare but potential pre-exec child process deadlock in
|
|
|
subprocess on POSIX systems when marking file descriptors inheritable on
|
|
|
exec in the child process. This bug appears to have been introduced in
|
|
|
3.4.
|
|
|
|
|
|
- bpo-32647: The ctypes module used to depend on indirect linking for
|
|
|
dlopen. The shared extension is now explicitly linked against libdl on
|
|
|
platforms with dl.
|
|
|
|
|
|
- bpo-32741: Implement ``asyncio.TimerHandle.when()`` method.
|
|
|
|
|
|
- bpo-32691: Use mod_spec.parent when running modules with pdb
|
|
|
|
|
|
- bpo-32734: Fixed ``asyncio.Lock()`` safety issue which allowed acquiring
|
|
|
and locking the same lock multiple times, without it being free. Patch by
|
|
|
Bar Harel.
|
|
|
|
|
|
- bpo-32727: Do not include name field in SMTP envelope from address. Patch
|
|
|
by Stéphane Wirtel
|
|
|
|
|
|
- bpo-31453: Add TLSVersion constants and SSLContext.maximum_version /
|
|
|
minimum_version attributes. The new API wraps OpenSSL 1.1
|
|
|
https://www.openssl.org/docs/man1.1.0/ssl/SSL_CTX_set_min_proto_version.html
|
|
|
feature.
|
|
|
|
|
|
- bpo-24334: Internal implementation details of ssl module were cleaned up.
|
|
|
The SSLSocket has one less layer of indirection. Owner and session
|
|
|
information are now handled by the SSLSocket and SSLObject constructor.
|
|
|
Channel binding implementation has been simplified.
|
|
|
|
|
|
- bpo-31848: Fix the error handling in Aifc_read.initfp() when the SSND
|
|
|
chunk is not found. Patch by Zackery Spytz.
|
|
|
|
|
|
- bpo-32585: Add Ttk spinbox widget to :mod:`tkinter.ttk`. Patch by Alan D
|
|
|
Moore.
|
|
|
|
|
|
- bpo-32221: Various functions returning tuple containing IPv6 addresses now
|
|
|
omit ``%scope`` part since the same information is already encoded in
|
|
|
*scopeid* tuple item. Especially this speeds up :func:`socket.recvfrom`
|
|
|
when it receives multicast packet since useless resolving of network
|
|
|
interface name is omitted.
|
|
|
|
|
|
- bpo-30693: The TarFile class now recurses directories in a reproducible
|
|
|
way.
|
|
|
|
|
|
- bpo-30693: The ZipFile class now recurses directories in a reproducible
|
|
|
way.
|

|
|
|
|
|
|
- bpo-32905: Remove unused code in pyparse module.
|
|
|
|
|
|
- bpo-32874: Add tests for pyparse.
|
|
|
|
|
|
- bpo-32837: Using the system and place-dependent default encoding for
|
|
|
open() is a bad idea for IDLE's system and location-independent files.
|
|
|
|
|
|
- bpo-32826: Add "encoding=utf-8" to open() in IDLE's test_help_about. GUI
|
|
|
test test_file_buttons() only looks at initial ascii-only lines, but
|
|
|
failed on systems where open() defaults to 'ascii' because readline()
|
|
|
internally reads and decodes far enough ahead to encounter a non-ascii
|
|
|
character in CREDITS.txt.
|
|
|
|
|
|
- bpo-32765: Update configdialog General tab docstring to add new widgets to
|
|
|
the widget list.
|
|
|
|
|

|
|
|
- bpo-32222: Fix pygettext not extracting docstrings for functions with type
|

What's New in Python 3.7.0 beta 1?
|
|
|
==================================
|
|
|
|
|
|
*Release date: 2018-01-30*
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-32703: Fix coroutine's ResourceWarning when there's an active error
|
|
|
set when it's being finalized.
|
|
|
|
|
|
- bpo-32650: Pdb and other debuggers dependent on bdb.py will correctly step
|
|
|
over (next command) native coroutines. Patch by Pablo Galindo.
|
|
|
|
|
|
- bpo-28685: Optimize list.sort() and sorted() by using type specialized
|
|
|
comparisons when possible.
|
|
|
|
|
|
- bpo-32685: Improve suggestion when the Python 2 form of print statement is
|
|
|
either present on the same line as the header of a compound statement or
|
|
|
else terminated by a semi-colon instead of a newline. Patch by Nitish
|
|
|
Chandra.
|
|
|
|
|
|
- bpo-32697: Python now explicitly preserves the definition order of
|
|
|
keyword-only parameters. It's always preserved their order, but this
|
|
|
behavior was never guaranteed before; this behavior is now guaranteed and
|
|
|
tested.
|
|
|
|
|
|
- bpo-32690: The locals() dictionary now displays in the lexical order that
|
|
|
variables were defined. Previously, the order was reversed.
|
|
|
|
|
|
- bpo-32677: Add ``.isascii()`` method to ``str``, ``bytes`` and
|
|
|
``bytearray``. It can be used to test that string contains only ASCII
|
|
|
characters.
|
|
|
|
|
|
- bpo-32670: Enforce :pep:`479` for all code.
|
|
|
|
|
|
This means that manually raising a StopIteration exception from a
|
|
|
generator is prohibited for all code, regardless of whether 'from
|
|
|
__future__ import generator_stop' was used or not.
|
|
|
|
|
|
- bpo-32591: Added built-in support for tracking the origin of coroutine
|
|
|
objects; see sys.set_coroutine_origin_tracking_depth and
|
|
|
CoroutineType.cr_origin. This replaces the asyncio debug mode's use of
|
|
|
coroutine wrapping for native coroutine objects.
|
|
|
|
|
|
- bpo-31368: Expose preadv and pwritev system calls in the os module. Patch
|
|
|
by Pablo Galindo
|
|
|
|
|
|
- bpo-32544: ``hasattr(obj, name)`` and ``getattr(obj, name, default)`` are
|
|
|
about 4 times faster than before when ``name`` is not found and ``obj``
|
|
|
doesn't override ``__getattr__`` or ``__getattribute__``.
|
|
|
|
|
|
- bpo-26163: Improved frozenset() hash to create more distinct hash values
|
|
|
when faced with datasets containing many similar values.
|
|
|
|
|
|
- bpo-32550: Remove the STORE_ANNOTATION bytecode.
|
|
|
|
|
|
- bpo-20104: Expose posix_spawn as a low level API in the os module.
|
|
|
(removed before 3.7.0rc1)
|
|
|
|
|
|
- bpo-24340: Fixed estimation of the code stack size.
|
|
|
|
|
|
- bpo-32436: Implement :pep:`567` Context Variables.
|
|
|
|
|
|
- bpo-18533: ``repr()`` on a dict containing its own ``values()`` or
|
|
|
``items()`` no longer raises ``RecursionError``; OrderedDict similarly.
|
|
|
Instead, use ``...``, as for other recursive structures. Patch by Ben
|
|
|
North.
|
|
|
|
|
|
- bpo-20891: Py_Initialize() now creates the GIL. The GIL is no longer
|
|
|
created "on demand" to fix a race condition when PyGILState_Ensure() is
|
|
|
called in a non-Python thread.
|
|
|
|
|
|
- bpo-32028: Leading whitespace is now correctly ignored when generating
|
|
|
suggestions for converting Py2 print statements to Py3 builtin print
|
|
|
function calls. Patch by Sanyam Khurana.
|
|
|
|
|
|
- bpo-31179: Make dict.copy() up to 5.5 times faster.
|
|
|
|
|
|
- bpo-31113: Get rid of recursion in the compiler for normal control flow.
|
|
|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-25988: Deprecate exposing the contents of collections.abc in the
|
|
|
regular collections module.
|
|
|
|
|
|
- bpo-31429: The default cipher suite selection of the ssl module now uses a
|
|
|
blacklist approach rather than a hard-coded whitelist. Python no longer
|
|
|
re-enables ciphers that have been blocked by OpenSSL security update.
|
|
|
Default cipher suite selection can be configured on compile time.
|
|
|
|
|
|
- bpo-30306: contextlib.contextmanager now releases the arguments passed to
|
|
|
the underlying generator as soon as the context manager is entered.
|
|
|
Previously it would keep them alive for as long as the context manager was
|
|
|
alive, even when not being used as a function decorator. Patch by Martin
|
|
|
Teichmann.
|
|
|
|
|
|
- bpo-21417: Added support for setting the compression level for
|
|
|
zipfile.ZipFile.
|
|
|
|
|
|
- bpo-32251: Implement asyncio.BufferedProtocol (provisional API).
|
|
|
|
|
|
- bpo-32513: In dataclasses, allow easier overriding of dunder methods
|
|
|
without specifying decorator parameters.
|
|
|
|
|
|
- bpo-32660: :mod:`termios` makes available ``FIONREAD``, ``FIONCLEX``,
|
|
|
``FIOCLEX``, ``FIOASYNC`` and ``FIONBIO`` also under Solaris/derivatives.
|
|
|
|
|
|
- bpo-27931: Fix email address header parsing error when the username is an
|
|
|
empty quoted string. Patch by Xiang Zhang.
|
|
|
|
|
|
- bpo-32659: Under Solaris and derivatives, :class:`os.stat_result` provides
|
|
|
a st_fstype attribute.
|
|
|
|
|
|
- bpo-32662: Implement Server.start_serving(), Server.serve_forever(), and
|
|
|
Server.is_serving() methods. Add 'start_serving' keyword parameter to
|
|
|
loop.create_server() and loop.create_unix_server().
|
|
|
|
|
|
- bpo-32391: Implement :meth:`asyncio.StreamWriter.wait_closed` and
|
|
|
:meth:`asyncio.StreamWriter.is_closing` methods
|
|
|
|
|
|
- bpo-32643: Make Task._step, Task._wakeup and Future._schedule_callbacks
|
|
|
methods private.
|
|
|
|
|
|
- bpo-32630: Refactor decimal module to use contextvars to store decimal
|
|
|
context.
|
|
|
|
|
|
- bpo-32622: Add :meth:`asyncio.AbstractEventLoop.sendfile` method.
|
|
|
|
|
|
- bpo-32304: distutils' upload command no longer corrupts tar files ending
|
|
|
with a CR byte, and no longer tries to convert CR to CRLF in any of the
|
|
|
upload text fields.
|
|
|
|
|
|
- bpo-32502: uuid.uuid1 no longer raises an exception if a 64-bit hardware
|
|
|
address is encountered.
|
|
|
|
|
|
- bpo-32596: ``concurrent.futures`` imports ``ThreadPoolExecutor`` and
|
|
|
``ProcessPoolExecutor`` lazily (using :pep:`562`). It makes ``import
|
|
|
asyncio`` about 15% faster because asyncio uses only
|
|
|
``ThreadPoolExecutor`` by default.
|
|
|
|
|
|
- bpo-31801: Add ``_ignore_`` to ``Enum`` so temporary variables can be used
|
|
|
during class construction without being turned into members.
|
|
|
|
|
|
- bpo-32576: Use queue.SimpleQueue() in places where it can be invoked from
|
|
|
a weakref callback.
|
|
|
|
|
|
- bpo-32574: Fix memory leak in asyncio.Queue, when the queue has limited
|
|
|
size and it is full, the cancelation of queue.put() can cause a memory
|
|
|
leak. Patch by: José Melero.
|
|
|
|
|
|
- bpo-32521: The nis module is now compatible with new libnsl and headers
|
|
|
location.
|
|
|
|
|
|
- bpo-32467: collections.abc.ValuesView now inherits from
|
|
|
collections.abc.Collection.
|
|
|
|
|
|
- bpo-32473: Improve ABCMeta._dump_registry() output readability
|
|
|
|
|
|
- bpo-32102: New argument ``capture_output`` for subprocess.run
|
|
|
|
|
|
- bpo-32521: glibc has removed Sun RPC. Use replacement libtirpc headers and
|
|
|
library in nis module.
|
|
|
|
|
|
- bpo-32493: UUID module fixes build for FreeBSD/OpenBSD
|
|
|
|
|
|
- bpo-32503: Pickling with protocol 4 no longer creates too small frames.
|
|
|
|
|
|
- bpo-29237: Create enum for pstats sorting options
|
|
|
|
|
|
- bpo-32454: Add close(fd) function to the socket module.
|
|
|
|
|
|
- bpo-25942: The subprocess module is now more graceful when handling a
|
|
|
Ctrl-C KeyboardInterrupt during subprocess.call, subprocess.run, or a
|
|
|
Popen context manager. It now waits a short amount of time for the child
|
|
|
(presumed to have also gotten the SIGINT) to exit, before continuing the
|
|
|
KeyboardInterrupt exception handling. This still includes a SIGKILL in
|
|
|
the call() and run() APIs, but at least the child had a chance first.
|
|
|
|
|
|
- bpo-32433: The hmac module now has hmac.digest(), which provides an
|
|
|
optimized HMAC digest.
|
|
|
|
|
|
- bpo-28134: Sockets now auto-detect family, type and protocol from file
|
|
|
descriptor by default.
|
|
|
|
|
|
- bpo-32404: Fix bug where :meth:`datetime.datetime.fromtimestamp` did not
|
|
|
call __new__ in :class:`datetime.datetime` subclasses.
|
|
|
|
|
|
- bpo-32403: Improved speed of :class:`datetime.date` and
|
|
|
:class:`datetime.datetime` alternate constructors.
|
|
|
|
|
|
- bpo-32228: Ensure that ``truncate()`` preserves the file position (as
|
|
|
reported by ``tell()``) after writes longer than the buffer size.
|
|
|
|
|
|
- bpo-32410: Implement ``loop.sock_sendfile`` for asyncio event loop.
|
|
|
|
|
|
- bpo-22908: Added seek and tell to the ZipExtFile class. This only works if
|
|
|
the file object used to open the zipfile is seekable.
|
|
|
|
|
|
- bpo-32373: Add socket.getblocking() method.
|
|
|
|
|
|
- bpo-32248: Add :mod:`importlib.resources` and
|
|
|
:class:`importlib.abc.ResourceReader` as the unified API for reading
|
|
|
resources contained within packages. Loaders wishing to support resource
|
|
|
reading must implement the :meth:`get_resource_reader()` method.
|
|
|
File-based and zipimport-based loaders both implement these APIs.
|
|
|
:class:`importlib.abc.ResourceLoader` is deprecated in favor of these new
|
|
|
APIs.
|
|
|
|
|
|
- bpo-32320: collections.namedtuple() now supports default values.
|
|
|
|
|
|
- bpo-29302: Add contextlib.AsyncExitStack. Patch by Alexander Mohr and Ilya
|
|
|
Kulakov.
|
|
|
|
|
|
- bpo-31961: *Removed in Python 3.7.0b2.* The *args* argument of
|
|
|
subprocess.Popen can now be a :term:`path-like object`. If *args* is given
|
|
|
as a sequence, it's first element can now be a :term:`path-like object` as
|
|
|
well.
|
|
|
|
|
|
- bpo-31900: The :func:`locale.localeconv` function now sets temporarily the
|
|
|
``LC_CTYPE`` locale to the ``LC_NUMERIC`` locale to decode
|
|
|
``decimal_point`` and ``thousands_sep`` byte strings if they are non-ASCII
|
|
|
or longer than 1 byte, and the ``LC_NUMERIC`` locale is different than the
|
|
|
``LC_CTYPE`` locale. This temporary change affects other threads.
|
|
|
|
|
|
Same change for the :meth:`str.format` method when formatting a number
|
|
|
(:class:`int`, :class:`float`, :class:`float` and subclasses) with the
|
|
|
``n`` type (ex: ``'{:n}'.format(1234)``).
|
|
|
|
|
|
- bpo-31853: Use super().method instead of socket.method in SSLSocket. They
|
|
|
were there most likely for legacy reasons.
|
|
|
|
|
|
- bpo-31399: The ssl module now uses OpenSSL's X509_VERIFY_PARAM_set1_host()
|
|
|
and X509_VERIFY_PARAM_set1_ip() API to verify hostname and IP addresses.
|
|
|
Subject common name fallback can be disabled with
|
|
|
SSLContext.hostname_checks_common_name.
|
|
|
|
|
|
- bpo-14976: Add a queue.SimpleQueue class, an unbounded FIFO queue with a
|
|
|
reentrant C implementation of put().
|
|
|
|
|
|
Documentation
|
|
|
-------------
|
|
|
|
|
|
- bpo-32724: Add references to some commands in the documentation of Pdb.
|
|
|
Patch by Stéphane Wirtel
|
|
|
|
|
|
- bpo-32649: Complete the C API documentation, profiling and tracing part
|
|
|
with the newly added per-opcode events.
|
|
|
|
|
|
- bpo-17799: Explain real behaviour of sys.settrace and sys.setprofile and
|
|
|
their C-API counterparts regarding which type of events are received in
|
|
|
each function. Patch by Pablo Galindo Salgado.
|
|
|
|
|
|
Tests
|
|
|
-----
|
|
|
|
|
|
- bpo-32721: Fix test_hashlib to not fail if the _md5 module is not built.
|
|
|
|
|
|
- bpo-28414: Add test cases for IDNA 2003 and 2008 host names. IDNA 2003
|
|
|
internationalized host names are working since bpo-31399 has landed. IDNA
|
|
|
2008 are still broken.
|
|
|
|
|
|
- bpo-32604: Add a new "_xxsubinterpreters" extension module that exposes
|
|
|
the existing subinterpreter C-API and a new cross-interpreter data sharing
|
|
|
mechanism. The module is primarily intended for more thorough testing of
|
|
|
the existing subinterpreter support.
|
|
|
|
|
|
Note that the _xxsubinterpreters module has been removed in 3.7.0rc1.
|
|
|
|
|
|
- bpo-32602: Add test certs and test for ECDSA cert and EC/RSA dual mode.
|
|
|
|
|
|
- bpo-32549: On Travis CI, Python now Compiles and uses a local copy of
|
|
|
OpenSSL 1.1.0g for testing.
|
|
|
|
|
|
Build
|
|
|
-----
|
|
|
|
|
|
- bpo-32635: Fix segfault of the crypt module when libxcrypt is provided
|
|
|
instead of libcrypt at the system.
|
|
|
|
|
|
- bpo-32598: Use autoconf to detect OpenSSL libs, headers and supported
|
|
|
features. The ax_check_openssl M4 macro uses pkg-config to locate OpenSSL
|
|
|
and falls back to manual search.
|
|
|
|
|
|
- bpo-32593: Drop support of FreeBSD 9 and older.
|
|
|
|
|
|
- bpo-29708: If the :envvar:`SOURCE_DATE_EPOCH` environment variable is set,
|
|
|
:mod:`py_compile` will always create hash-based ``.pyc`` files.
|
|
|
|
|
|
Windows
|
|
|
-------
|
|
|
|
|
|
- bpo-32588: Create standalone _distutils_findvs module and add missing
|
|
|
_queue module to installer.
|
|
|
|
|
|
- bpo-29911: Ensure separate Modify and Uninstall buttons are displayed.
|
|
|
|
|
|
- bpo-32507: Use app-local UCRT install rather than the proper update for
|
|
|
old versions of Windows.
|
|
|
|
|
|
macOS
|
|
|
-----
|
|
|
|
|
|
- bpo-32726: Provide an additional, more modern macOS installer variant that
|
|
|
supports macOS 10.9+ systems in 64-bit mode only. Upgrade the supplied
|
|
|
third-party libraries to OpenSSL 1.1.0g and to SQLite 3.22.0. The 10.9+
|
|
|
installer now links with and supplies its own copy of Tcl/Tk 8.6.
|
|
|
|
|
|
- bpo-28440: No longer add /Library/Python/3.x/site-packages to sys.path for
|
|
|
macOS framework builds to avoid future conflicts.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-32681: Fix uninitialized variable 'res' in the C implementation of
|
|
|
os.dup2. Patch by Stéphane Wirtel
|
|
|
|
|
|
- bpo-10381: Add C API access to the ``datetime.timezone`` constructor and
|
|
|
``datetime.timzone.UTC`` singleton.
|
|

|
What's New in Python 3.7.0 alpha 4?
|
|
|
===================================
|
|
|
|
|
|
*Release date: 2018-01-08*
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-31975: The default warning filter list now starts with a
|
|
|
"default::DeprecationWarning:__main__" entry, so deprecation warnings are
|
|
|
once again shown by default in single-file scripts and at the interactive
|
|
|
prompt.
|
|
|
|
|
|
- bpo-32226: ``__class_getitem__`` is now an automatic class method.
|
|
|
|
|
|
- bpo-32399: Add AIX uuid library support for RFC4122 using uuid_create() in
|
|
|
libc.a
|
|
|
|
|
|
- bpo-32390: Fix the compilation failure on AIX after the f_fsid field has
|
|
|
been added to the object returned by os.statvfs() (issue #32143). Original
|
|
|
patch by Michael Felt.
|
|
|
|
|
|
- bpo-32379: Make MRO computation faster when a class inherits from a single
|
|
|
base.
|
|
|
|
|
|
- bpo-32259: The error message of a TypeError raised when unpack
|
|
|
non-iterable is now more specific.
|
|
|
|
|
|
- bpo-27169: The ``__debug__`` constant is now optimized out at compile
|
|
|
time. This fixes also bpo-22091.
|
|
|
|
|
|
- bpo-32329: The :option:`-R` option now turns on hash randomization when
|
|
|
the :envvar:`PYTHONHASHSEED` environment variable is set to ``0``.
|
|
|
Previously, the option was ignored. Moreover,
|
|
|
``sys.flags.hash_randomization`` is now properly set to 0 when hash
|
|
|
randomization is turned off by ``PYTHONHASHSEED=0``.
|
|
|
|
|
|
- bpo-30416: The optimizer is now protected from spending much time doing
|
|
|
complex calculations and consuming much memory for creating large
|
|
|
constants in constant folding. Increased limits for constants that can be
|
|
|
produced in constant folding.
|
|
|
|
|
|
- bpo-32282: Fix an unnecessary ifdef in the include of VersionHelpers.h in
|
|
|
socketmodule on Windows.
|
|
|
|
|
|
- bpo-30579: Implement TracebackType.__new__ to allow Python-level creation
|
|
|
of traceback objects, and make TracebackType.tb_next mutable.
|
|
|
|
|
|
- bpo-32260: Don't byte swap the input keys to the SipHash algorithm on
|
|
|
big-endian platforms. This should ensure siphash gives consistent results
|
|
|
across platforms.
|
|
|
|
|
|
- bpo-31506: Improve the error message logic for object.__new__ and
|
|
|
object.__init__. Patch by Sanyam Khurana.
|
|
|
|
|
|
- bpo-20361: ``-b`` and ``-bb`` now inject ``'default::BytesWarning'`` and
|
|
|
``error::BytesWarning`` entries into ``sys.warnoptions``, ensuring that
|
|
|
they take precedence over any other warning filters configured via the
|
|
|
``-W`` option or the ``PYTHONWARNINGS`` environment variable.
|
|
|
|
|
|
- bpo-32230: `-X dev` now injects a ``'default'`` entry into
|
|
|
sys.warnoptions, ensuring that it behaves identically to actually passing
|
|
|
``-Wdefault`` at the command line.
|
|
|
|
|
|
- bpo-29240: Add a new UTF-8 mode: implementation of the :pep:`540`.
|
|
|
|
|
|
- bpo-32226: :pep:`560`: Add support for ``__mro_entries__`` and
|
|
|
``__class_getitem__``. Implemented by Ivan Levkivskyi.
|
|
|
|
|
|
- bpo-32225: :pep:`562`: Add support for module ``__getattr__`` and
|
|
|
``__dir__``. Implemented by Ivan Levkivskyi.
|
|
|
|
|
|
- bpo-31901: The `atexit` module now has its callback stored per
|
|
|
interpreter.
|
|
|
|
|
|
- bpo-31650: Implement :pep:`552` (Deterministic pycs). Python now supports
|
|
|
invalidating bytecode cache files bashed on a source content hash rather
|
|
|
than source last-modified time.
|
|
|
|
|
|
- bpo-29469: Move constant folding from bytecode layer to AST layer.
|
|
|
Original patch by Eugene Toder.

Library
|
|
|
-------
|
|
|
|
|
|
- bpo-32506: Now that dict is defined as keeping insertion order, drop
|
|
|
OrderedDict and just use plain dict.
|
|
|
|
|
|
- bpo-32279: Add params to dataclasses.make_dataclasses(): init, repr, eq,
|
|
|
order, hash, and frozen. Pass them through to dataclass().
|
|
|
|
|
|
- bpo-32278: Make type information optional on dataclasses.make_dataclass().
|
|
|
If omitted, the string 'typing.Any' is used.
|
|
|
|
|
|
- bpo-32499: Add dataclasses.is_dataclass(obj), which returns True if obj is
|
|
|
a dataclass or an instance of one.
|
|
|
|
|
|
- bpo-32468: Improve frame repr() to mention filename, code name and current
|
|
|
line number.
|
|
|
|
|
|
- bpo-23749: asyncio: Implement loop.start_tls()
|
|
|
|
|
|
- bpo-32441: Return the new file descriptor (i.e., the second argument) from
|
|
|
``os.dup2``. Previously, ``None`` was always returned.
|
|
|
|
|
|
- bpo-32422: ``functools.lru_cache`` uses less memory (3 words for each
|
|
|
cached key) and takes about 1/3 time for cyclic GC.
|
|
|
|
|
|
- bpo-31721: Prevent Python crash from happening when Future._log_traceback
|
|
|
is set to True manually. Now it can only be set to False, or a ValueError
|
|
|
is raised.
|
|
|
|
|
|
- bpo-32415: asyncio: Add Task.get_loop() and Future.get_loop()
|
|
|
|
|
|
- bpo-26133: Don't unsubscribe signals in asyncio UNIX event loop on
|
|
|
interpreter shutdown.
|
|
|
|
|
|
- bpo-32363: Make asyncio.Task.set_exception() and set_result() raise
|
|
|
NotImplementedError. Task._step() and Future.__await__() raise proper
|
|
|
exceptions when they are in an invalid state, instead of raising an
|
|
|
AssertionError.
|
|
|
|
|
|
- bpo-32357: Optimize asyncio.iscoroutine() and loop.create_task() for
|
|
|
non-native coroutines (e.g. async/await compiled with Cython).
|
|
|
|
|
|
'loop.create_task(python_coroutine)' used to be 20% faster than
|
|
|
'loop.create_task(cython_coroutine)'. Now, the latter is as fast.
|
|
|
|
|
|
- bpo-32356: asyncio.transport.resume_reading() and pause_reading() are now
|
|
|
idempotent. New transport.is_reading() method is added.
|
|
|
|
|
|
- bpo-32355: Optimize asyncio.gather(); now up to 15% faster.
|
|
|
|
|
|
- bpo-32351: Use fastpath in asyncio.sleep if delay<0 (2x boost)
|
|
|
|
|
|
- bpo-32348: Optimize asyncio.Future schedule/add/remove callback. The
|
|
|
optimization shows 3-6% performance improvements of async/await code.
|
|
|
|
|
|
- bpo-32331: Fix socket.settimeout() and socket.setblocking() to keep
|
|
|
socket.type as is. Fix socket.socket() constructor to reset any bit flags
|
|
|
applied to socket's type. This change only affects OSes that have
|
|
|
SOCK_NONBLOCK and/or SOCK_CLOEXEC.
|
|
|
|
|
|
- bpo-32248: Add :class:`importlib.abc.ResourceReader` as an ABC for loaders
|
|
|
to provide a unified API for reading resources contained within packages.
|
|
|
Also add :mod:`importlib.resources` as the port of
|
|
|
``importlib_resources``.
|
|
|
|
|
|
- bpo-32311: Implement asyncio.create_task(coro) shortcut
|
|
|
|
|
|
- bpo-32327: Convert asyncio functions that were documented as coroutines to
|
|
|
coroutines. Affected functions: loop.sock_sendall, loop.sock_recv,
|
|
|
loop.sock_accept, loop.getaddrinfo, loop.getnameinfo.
|
|
|
|
|
|
- bpo-32323: :func:`urllib.parse.urlsplit()` does not convert zone-id
|
|
|
(scope) to lower case for scoped IPv6 addresses in hostnames now.
|
|
|
|
|
|
- bpo-32302: Fix bdist_wininst of distutils for CRT v142: it binary
|
|
|
compatible with CRT v140.
|
|
|
|
|
|
- bpo-29711: Fix ``stop_serving`` in asyncio proactor loop kill all
|
|
|
listening servers
|
|
|
|
|
|
- bpo-32308: :func:`re.sub()` now replaces empty matches adjacent to a
|
|
|
previous non-empty match.
|
|
|
|
|
|
- bpo-29970: Abort asyncio SSLProtocol connection if handshake not complete
|
|
|
within 10s
|
|
|
|
|
|
- bpo-32314: Implement asyncio.run().
|
|
|
|
|
|
- bpo-17852: Revert incorrect fix based on misunderstanding of
|
|
|
_Py_PyAtExit() semantics.
|
|
|
|
|
|
- bpo-32296: Implement asyncio._get_running_loop() and get_event_loop() in
|
|
|
C. This makes them 4x faster.
|
|
|
|
|
|
- bpo-32250: Implement ``asyncio.current_task()`` and
|
|
|
``asyncio.all_tasks()``. Add helpers intended to be used by alternative
|
|
|
task implementations: ``asyncio._register_task``, ``asyncio._enter_task``,
|
|
|
``asyncio._leave_task`` and ``asyncio._unregister_task``. Deprecate
|
|
|
``asyncio.Task.current_task()`` and ``asyncio.Task.all_tasks()``.
|
|
|
|
|
|
- bpo-32255: A single empty field is now always quoted when written into a
|
|
|
CSV file. This allows to distinguish an empty row from a row consisting of
|
|
|
a single empty field. Patch by Licht Takeuchi.
|
|
|
|
|
|
- bpo-32277: Raise ``NotImplementedError`` instead of ``SystemError`` on
|
|
|
platforms where ``chmod(..., follow_symlinks=False)`` is not supported.
|
|
|
Patch by Anthony Sottile.
|
|
|
|
|
|
- bpo-30050: New argument warn_on_full_buffer to signal.set_wakeup_fd lets
|
|
|
you control whether Python prints a warning on stderr when the wakeup fd
|
|
|
buffer overflows.
|
|
|
|
|
|
- bpo-29137: The ``fpectl`` library has been removed. It was never enabled
|
|
|
by default, never worked correctly on x86-64, and it changed the Python
|
|
|
ABI in ways that caused unexpected breakage of C extensions.
|
|
|
|
|
|
- bpo-32273: Move asyncio.test_utils to test.test_asyncio.
|
|
|
|
|
|

|
|
|
|
|
|
- bpo-32269: Add asyncio.get_running_loop() function.
|
|
|
|
|
|
- bpo-32265: All class and static methods of builtin types now are correctly
|
|
|
classified by inspect.classify_class_attrs() and grouped in pydoc ouput.
|
|
|
Added types.ClassMethodDescriptorType for unbound class methods of builtin
|
|
|
types.
|
|
|
|
|
|
- bpo-32253: Deprecate ``yield from lock``, ``await lock``, ``with (yield
|
|
|
from lock)`` and ``with await lock`` for asyncio synchronization
|
|
|
primitives.
|
|
|
|
|
|
- bpo-22589: Changed MIME type of .bmp from 'image/x-ms-bmp' to 'image/bmp'
|
|
|
|
|
|
- bpo-32193: Convert asyncio to use *async/await* syntax. Old styled ``yield
|
|
|
from`` is still supported too.
|
|
|
|
|
|
- bpo-32206: Add support to run modules with pdb
|
|
|
|
|
|
- bpo-32227: ``functools.singledispatch`` now supports registering
|
|
|
implementations using type annotations.
|
|
|
|
|
|
- bpo-15873: Added new alternate constructors
|
|
|
:meth:`datetime.datetime.fromisoformat`,
|
|
|
:meth:`datetime.time.fromisoformat` and
|
|
|
:meth:`datetime.date.fromisoformat` as the inverse operation of each
|
|
|
classes's respective ``isoformat`` methods.
|
|
|
|
|
|
- bpo-32199: The getnode() ip getter now uses 'ip link' instead of 'ip link
|
|
|
list'.
|
|
|
|
|
|
- bpo-32143: os.statvfs() includes the f_fsid field from statvfs(2)
|
|
|
|
|
|
- bpo-26439: Fix ctypes.util.find_library() for AIX by implementing
|
|
|
ctypes._aix.find_library() Patch by: Michael Felt
|
|
|
|
|
|
- bpo-31993: The pickler now uses less memory when serializing large bytes
|
|
|
and str objects into a file. Pickles created with protocol 4 will require
|
|
|
less memory for unpickling large bytes and str objects.
|
|
|
|
|
|
- bpo-27456: Ensure TCP_NODELAY is set on Linux. Tests by Victor Stinner.
|
|
|
|
|
|
- bpo-31778: ast.literal_eval() is now more strict. Addition and subtraction
|
|
|
of arbitrary numbers no longer allowed.
|
|
|
|
|
|
- bpo-31802: Importing native path module (``posixpath``, ``ntpath``) now
|
|
|
works even if the ``os`` module still is not imported.
|
|
|
|
|
|
- bpo-30241: Add contextlib.AbstractAsyncContextManager. Patch by Jelle
|
|
|
Zijlstra.
|
|
|
|
|
|
- bpo-31699: Fix deadlocks in
|
|
|
:class:`concurrent.futures.ProcessPoolExecutor` when task arguments or
|
|
|
results cause pickling or unpickling errors. This should make sure that
|
|
|
calls to the :class:`ProcessPoolExecutor` API always eventually return.
|
|
|
|
|
|
- bpo-15216: ``TextIOWrapper.reconfigure()`` supports changing *encoding*,
|
|
|
*errors*, and *newline*.

-----
|
|
|
|
|
|
- bpo-32252: Fix faulthandler_suppress_crash_report() used to prevent core

- bpo-24960: 2to3 and lib2to3 can now read pickled grammar files using
|
|
|
pkgutil.get_data() rather than probing the filesystem. This lets 2to3 and
|
|
|
lib2to3 work when run from a zipfile.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-32030: Py_Initialize() doesn't reset the memory allocators to default
|
|
|
if the ``PYTHONMALLOC`` environment variable is not set.
|
|
|
|
|
|
- bpo-29084: Undocumented C API for OrderedDict has been excluded from the
|
|
|
limited C API. It was added by mistake and actually never worked in the
|
|
|
limited C API.
|
|
|
|
|
|
- bpo-32264: Moved the pygetopt.h header into internal/, since it has no
|
|
|
public APIs.
|
|
|
|
|

What's New in Python 3.7.0 alpha 3?
|
|
|
===================================
|
|
|
|
|
|
*Release date: 2017-12-05*
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-32176: co_flags.CO_NOFREE is now always set correctly by the code
|
|
|
object constructor based on freevars and cellvars, rather than needing to
|
|
|
be set correctly by the caller. This ensures it will be cleared
|
|
|
automatically when additional cell references are injected into a modified
|
|
|
code object and function.
|
|
|
|
|
|
- bpo-10544: Yield expressions are now deprecated in comprehensions and
|
|
|
generator expressions. They are still permitted in the definition of the
|
|
|
outermost iterable, as that is evaluated directly in the enclosing scope.
|
|
|
|
|
|
- bpo-32137: The repr of deeply nested dict now raises a RecursionError
|
|
|
instead of crashing due to a stack overflow.
|
|
|
|
|
|
- bpo-32096: Revert memory allocator changes in the C API: move structures
|
|
|
back from _PyRuntime to Objects/obmalloc.c. The memory allocators are once
|
|
|
again initialized statically, and so PyMem_RawMalloc() and
|
|
|
Py_DecodeLocale() can be called before _PyRuntime_Initialize().
|
|
|
|
|
|
- bpo-32043: Add a new "developer mode": new "-X dev" command line option to
|
|
|
enable debug checks at runtime.
|
|
|
|
|
|
- bpo-32023: SyntaxError is now correctly raised when a generator expression
|
|
|
without parenthesis is used instead of an inheritance list in a class
|
|
|
definition. The duplication of the parentheses can be omitted only on
|
|
|
calls.
|
|
|
|
|
|
- bpo-32012: SyntaxError is now correctly raised when a generator expression
|
|
|
without parenthesis is passed as an argument, but followed by a trailing
|
|
|
comma. A generator expression always needs to be directly inside a set of
|
|
|
parentheses and cannot have a comma on either side.
|
|
|
|
|
|
- bpo-28180: A new internal ``_Py_SetLocaleFromEnv(category)`` helper
|
|
|
function has been added in order to improve the consistency of behaviour
|
|
|
across different ``libc`` implementations (e.g. Android doesn't support
|
|
|
setting the locale from the environment by default).
|
|
|
|
|
|
- bpo-31949: Fixed several issues in printing tracebacks
|
|
|
(PyTraceBack_Print()).
|
|
|
|
|
|
* Setting sys.tracebacklimit to 0 or less now suppresses printing tracebacks.
|
|
|
* Setting sys.tracebacklimit to None now causes using the default limit.
|
|
|
* Setting sys.tracebacklimit to an integer larger than LONG_MAX now means using
|
|
|
the limit LONG_MAX rather than the default limit.
|
|
|
* Fixed integer overflows in the case of more than 2**31 traceback items on
|
|
|
Windows.
|
|
|
* Fixed output errors handling.
|
|
|
|
|
|
- bpo-30696: Fix the interactive interpreter looping endlessly when no
|
|
|
memory.
|
|
|
|
|
|
- bpo-20047: Bytearray methods partition() and rpartition() now accept only
|
|
|
bytes-like objects as separator, as documented. In particular they now
|
|
|
raise TypeError rather of returning a bogus result when an integer is
|
|
|
passed as a separator.
|
|
|
|
|
|
- bpo-21720: BytesWarning no longer emitted when the *fromlist* argument of
|
|
|
``__import__()`` or the ``__all__`` attribute of the module contain bytes
|
|
|
instances.
|
|
|
|
|
|
- bpo-31845: Environment variables are once more read correctly at
|
|
|
interpreter startup.
|
|
|
|
|
|
- bpo-28936: Ensure that lexically first syntax error involving a parameter
|
|
|
and ``global`` or ``nonlocal`` is detected first at a given scope. Patch
|
|
|
by Ivan Levkivskyi.
|
|
|
|
|
|
- bpo-31825: Fixed OverflowError in the 'unicode-escape' codec and in
|
|
|
codecs.escape_decode() when decode an escaped non-ascii byte.
|
|
|
|
|
|
- bpo-31618: The per-frame tracing logic added in 3.7a1 has been altered so
|
|
|
that ``frame->f_lineno`` is updated before either ``"line"`` or
|
|
|
``"opcode"`` events are emitted. Previously, opcode events were emitted
|
|
|
first, and therefore would occasionally see stale line numbers on the
|
|
|
frame. The behavior of this feature has changed slightly as a result: when
|
|
|
both ``f_trace_lines`` and ``f_trace_opcodes`` are enabled, line events
|
|
|
now occur first.
|
|
|
|
|
|
- bpo-28603: Print the full context/cause chain of exceptions on interpreter
|
|
|
exit, even if an exception in the chain is unhashable or compares equal to
|
|
|
later ones. Patch by Zane Bitter.
|
|
|
|
|
|
- bpo-31786: Fix timeout rounding in the select module to round correctly
|
|
|
negative timeouts between -1.0 and 0.0. The functions now block waiting
|
|
|
for events as expected. Previously, the call was incorrectly non-blocking.
|
|
|
Patch by Pablo Galindo.
|
|
|
|
|
|
- bpo-31781: Prevent crashes when calling methods of an uninitialized
|
|
|
``zipimport.zipimporter`` object. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-30399: Standard repr() of BaseException with a single argument no
|
|
|
longer contains redundant trailing comma.
|
|
|
|
|
|
- bpo-31626: Fixed a bug in debug memory allocator. There was a write to
|
|
|
freed memory after shrinking a memory block.
|
|
|
|
|
|
- bpo-30817: `PyErr_PrintEx()` clears now the ignored exception that may be
|
|
|
raised by `_PySys_SetObjectId()`, for example when no memory.
|
|
|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-28556: Two minor fixes for ``typing`` module: allow shallow copying
|
|
|
instances of generic classes, improve interaction of ``__init_subclass__``
|
|
|
with generics. Original PRs by Ivan Levkivskyi.
|
|
|
|
|
|
- bpo-32214: PEP 557, Data Classes. Provides a decorator which adds
|
|
|
boilerplate methods to classes which use type annotations so specify
|
|
|
fields.
|
|
|
|
|
|
- bpo-27240: The header folding algorithm for the new email policies has
|
|
|
been rewritten, which also fixes bpo-30788, bpo-31831, and bpo-32182. In
|
|
|
particular, RFC2231 folding is now done correctly.
|
|
|
|
|
|
- bpo-32186: io.FileIO.readall() and io.FileIO.read() now release the GIL
|
|
|
when getting the file size. Fixed hang of all threads with inaccessible
|
|
|
NFS server. Patch by Nir Soffer.

|
|
|
- bpo-321010: Add :attr:`sys.flags.dev_mode` flag
|
|
|
|
|
|
- bpo-32154: The ``asyncio.windows_utils.socketpair()`` function has been
|
|
|
removed: use directly :func:`socket.socketpair` which is available on all
|
|
|
platforms since Python 3.5 (before, it wasn't available on Windows).
|
|
|
``asyncio.windows_utils.socketpair()`` was just an alias to
|
|
|
``socket.socketpair`` on Python 3.5 and newer.
|
|
|
|
|
|
- bpo-32089: warnings: In development (-X dev) and debug mode (pydebug
|
|
|
build), use the "default" action for ResourceWarning, rather than the
|
|
|
"always" action, in the default warnings filters.
|
|
|
|
|
|
- bpo-32107: ``uuid.getnode()`` now preferentially returns universally
|
|
|
administered MAC addresses if available, over locally administered MAC
|
|
|
addresses. This makes a better guarantee for global uniqueness of UUIDs
|
|
|
returned from ``uuid.uuid1()``. If only locally administered MAC
|
|
|
addresses are available, the first such one found is returned.
|
|
|
|
|
|
- bpo-23033: Wildcard is now supported in hostname when it is one and only
|
|
|
character in the left most segment of hostname in second argument of
|
|
|
:meth:`ssl.match_hostname`. Patch by Mandeep Singh.
|
|
|
|
|
|
- bpo-12239: Make :meth:`msilib.SummaryInformation.GetProperty` return
|
|
|
``None`` when the value of property is ``VT_EMPTY``. Initial patch by
|
|
|
Mark Mc Mahon.
|
|
|
|
|
|
- bpo-28334: Use :func:`os.path.expanduser` to find the ``~/.netrc`` file in
|
|
|
:class:`netrc.netrc`. If it does not exist, :exc:`FileNotFoundError` is
|
|
|
raised. Patch by Dimitri Merejkowsky.
|
|
|
|
|
|
- bpo-32121: Made ``tracemalloc.Traceback`` behave more like the traceback
|
|
|
module, sorting the frames from oldest to most recent.
|
|
|
``Traceback.format()`` now accepts negative *limit*, truncating the result
|
|
|
to the ``abs(limit)`` oldest frames. To get the old behaviour, one can use
|
|
|
the new *most_recent_first* argument to ``Traceback.format()``. (Patch by
|
|
|
Jesse Bakker.)
|
|
|
|
|
|
- bpo-31325: Fix wrong usage of :func:`collections.namedtuple` in the
|
|
|
:meth:`RobotFileParser.parse() <urllib.robotparser.RobotFileParser.parse>`
|
|
|
method.
|
|
|
|
|
|
Initial patch by Robin Wellner.
|
|
|
|
|
|
- bpo-12382: :func:`msilib.OpenDatabase` now raises a better exception
|
|
|
message when it couldn't open or create an MSI file. Initial patch by
|
|
|
William Tisäter.
|
|
|
|
|
|
- bpo-19610: ``setup()`` now warns about invalid types for some fields.
|
|
|
|
|
|
The ``distutils.dist.Distribution`` class now warns when ``classifiers``,
|
|
|
``keywords`` and ``platforms`` fields are not specified as a list or a
|
|
|
string.
|
|
|
|
|
|
- bpo-32071: Added the ``-k`` command-line option to ``python -m unittest``
|
|
|
to run only tests that match the given pattern(s).
|
|
|
|
|
|
- bpo-10049: Added *nullcontext* no-op context manager to contextlib. This
|
|
|
provides a simpler and faster alternative to ExitStack() when handling
|
|
|
optional context managers.
|
|
|
|
|
|
- bpo-28684: The new test.support.skip_unless_bind_unix_socket() decorator
|
|
|
is used here to skip asyncio tests that fail because the platform lacks a
|
|
|
functional bind() function for unix domain sockets (as it is the case for
|
|
|
non root users on the recent Android versions that run now SELinux in
|
|
|
enforcing mode).
|
|
|
|
|
|
- bpo-32110: ``codecs.StreamReader.read(n)`` now returns not more than *n*
|
|
|
characters/bytes for non-negative *n*. This makes it compatible with
|
|
|
``read()`` methods of other file-like objects.
|
|
|
|
|
|
- bpo-27535: The warnings module doesn't leak memory anymore in the hidden
|
|
|
warnings registry for the "ignore" action of warnings filters.
|
|
|
warn_explicit() function doesn't add the warning key to the registry
|
|
|
anymore for the "ignore" action.
|
|
|
|
|
|
- bpo-32088: warnings: When Python is build is debug mode (``Py_DEBUG``),
|
|
|
:exc:`DeprecationWarning`, :exc:`PendingDeprecationWarning` and
|
|
|
:exc:`ImportWarning` warnings are now displayed by default.
|
|
|
|
|
|
- bpo-1647489: Fixed searching regular expression patterns that could match
|
|
|
an empty string. Non-empty string can now be correctly found after
|
|
|
matching an empty string.
|
|
|
|
|
|
- bpo-25054: Added support of splitting on a pattern that could match an
|
|
|
empty string.
|
|
|
|
|
|
- bpo-32072: Fixed issues with binary plists:
|
|
|
|
|
|
* Fixed saving bytearrays.
|
|
|
* Identical objects will be saved only once.
|
|
|
* Equal references will be load as identical objects.
|
|
|
* Added support for saving and loading recursive data structures.
|
|
|
|
|
|
- bpo-32069: Drop legacy SSL transport from asyncio, ssl.MemoryBIO is always
|
|
|
used anyway.
|
|
|
|
|
|
- bpo-32066: asyncio: Support pathlib.Path in create_unix_connection; sock
|
|
|
arg should be optional
|
|
|
|
|
|
- bpo-32046: Updates 2to3 to convert from operator.isCallable(obj) to
|
|
|
callable(obj). Patch by Dong-hee Na.
|
|
|
|
|
|
- bpo-32018: inspect.signature should follow PEP 8, if the parameter has an
|
|
|
annotation and a default value. Patch by Dong-hee Na.
|
|
|
|
|
|
- bpo-32025: Add time.thread_time() and time.thread_time_ns()
|
|
|
|
|
|
- bpo-32037: Integers that fit in a signed 32-bit integer will be now
|
|
|
pickled with protocol 0 using the INT opcode. This will decrease the size
|
|
|
of a pickle, speed up pickling and unpickling, and make these integers be
|
|
|
unpickled as int instances in Python 2.
|
|
|
|
|
|
- bpo-32034: Make asyncio.IncompleteReadError and LimitOverrunError
|
|
|
pickleable.
|
|
|
|
|
|
- bpo-32015: Fixed the looping of asyncio in the case of reconnection the
|
|
|
socket during waiting async read/write from/to the socket.
|
|
|
|
|
|
- bpo-32011: Restored support of loading marshal files with the TYPE_INT64
|
|
|
code. These files can be produced in Python 2.7.
|
|
|
|
|
|
- bpo-28369: Enhance add_reader/writer check that socket is not used by some
|
|
|
transport. Before, only cases when add_reader/writer were called with an
|
|
|
int FD were supported. Now the check is implemented correctly for all
|
|
|
file-like objects.
|
|
|
|
|
|
- bpo-31976: Fix race condition when flushing a file is slow, which can
|
|
|
cause a segfault if closing the file from another thread.
|
|
|
|
|
|
- bpo-31985: Formally deprecated aifc.openfp, sunau.openfp, and wave.openfp.
|
|
|
Since change 7bc817d5ba917528e8bd07ec461c635291e7b06a in 1993, openfp in
|
|
|
each of the three modules had been pointing to that module's open function
|
|
|
as a matter of backwards compatibility, though it had been both untested
|
|
|
and undocumented.
|
|
|
|
|
|
- bpo-21862: cProfile command line now accepts `-m module_name` as an
|
|
|
alternative to script path. Patch by Sanyam Khurana.
|
|
|
|
|
|
- bpo-31970: Reduce performance overhead of asyncio debug mode.
|
|
|
|
|
|
- bpo-31843: *database* argument of sqlite3.connect() now accepts a
|
|
|
:term:`path-like object`, instead of just a string.
|
|
|
|
|
|
- bpo-31945: Add Configurable *blocksize* to ``HTTPConnection`` and
|
|
|
``HTTPSConnection`` for improved upload throughput. Patch by Nir Soffer.
|
|
|
|
|
|
- bpo-31943: Add a ``cancelled()`` method to :class:`asyncio.Handle`. Patch
|
|
|
by Marat Sharafutdinov.
|
|
|
|
|
|
- bpo-9678: Fixed determining the MAC address in the uuid module:
|
|
|
|
|
|
* Using ifconfig on NetBSD and OpenBSD.
|
|
|
* Using arp on Linux, FreeBSD, NetBSD and OpenBSD.
|
|

|
|
address on NetBSD and DragonFly BSD.
|
|
|
|
|
|
- bpo-27666: Fixed stack corruption in curses.box() and curses.ungetmouse()
|
|
|
when the size of types chtype or mmask_t is less than the size of C long.
|
|
|
curses.box() now accepts characters as arguments. Based on patch by Steve
|
|
|
Fink.
|
|
|
|
|
|
- bpo-31917: Add 3 new clock identifiers: :data:`time.CLOCK_BOOTTIME`,
|
|
|
:data:`time.CLOCK_PROF` and :data:`time.CLOCK_UPTIME`.
|
|
|
|
|
|
- bpo-31897: plistlib now catches more errors when read binary plists and
|
|
|
raises InvalidFileException instead of unexpected exceptions.
|
|
|
|
|
|
- bpo-25720: Fix the method for checking pad state of curses WINDOW. Patch
|
|
|
by Masayuki Yamamoto.

- bpo-31702: crypt.mksalt() now allows to specify the number of rounds for
|
|
|
SHA-256 and SHA-512 hashing.
|
|
|
|
|
|
- bpo-30639: :func:`inspect.getfile` no longer computes the repr of unknown
|
|
|
objects to display in an error message, to protect against badly behaved
|
|
|
custom reprs.
|
|
|
|
|
|
- bpo-30768: Fix the pthread+semaphore implementation of
|
|
|
PyThread_acquire_lock_timed() when called with timeout > 0 and
|
|
|
intr_flag=0: recompute the timeout if sem_timedwait() is interrupted by a
|
|
|
signal (EINTR). See also the :pep:`475`.
|
|
|
|
|
|
- bpo-31854: Add ``mmap.ACCESS_DEFAULT`` constant.
|
|
|
|
|
|
- bpo-31834: Use optimized code for BLAKE2 only with SSSE3+. The pure SSE2
|
|
|
implementation is slower than the pure C reference implementation.
|
|
|
|
|
|
- bpo-28292: Calendar.itermonthdates() will now consistently raise an
|
|
|
exception when a date falls outside of the 0001-01-01 through 9999-12-31
|
|
|
range. To support applications that cannot tolerate such exceptions, the
|
|
|
new methods itermonthdays3() and itermonthdays4() are added. The new
|
|
|
methods return tuples and are not restricted by the range supported by
|
|
|
datetime.date.
|
|
|
|
|
|
- bpo-28564: The shutil.rmtree() function has been sped up to 20--40%. This
|
|
|
was done using the os.scandir() function.
|
|
|
|
|
|
- bpo-28416: Instances of pickle.Pickler subclass with the persistent_id()
|
|
|
method and pickle.Unpickler subclass with the persistent_load() method no
|
|
|
longer create reference cycles.
|
|
|
|
|
|

|
|
|
or None.
|

|
|
- bpo-20825: Add `subnet_of` and `superset_of` containment tests to
|
|
|
:class:`ipaddress.IPv6Network` and :class:`ipaddress.IPv4Network`. Patch
|
|
|
by Michel Albert and Cheryl Sabella.
|
|
|
|
|
|
- bpo-31827: Remove the os.stat_float_times() function. It was introduced in
|
|
|
Python 2.3 for backward compatibility with Python 2.2, and was deprecated
|
|
|
since Python 3.1.
|
|
|
|
|
|
- bpo-31756: Add a ``subprocess.Popen(text=False)`` keyword argument to
|
|
|
`subprocess` functions to be more explicit about when the library should
|
|
|
attempt to decode outputs into text. Patch by Andrew Clegg.
|
|
|
|
|
|
- bpo-31819: Add AbstractEventLoop.sock_recv_into().

|
|
|
properly settable.
|
|
|
|
|
|

|
|
|
and socket.socket.settimeout() to round correctly negative timeouts
|
|
|
between -1.0 and 0.0. The functions now block waiting for events as
|
|
|
expected. Previously, the call was incorrectly non-blocking. Patch by
|
|
|
Pablo Galindo.
|
|
|
|
|
|
- bpo-31803: time.clock() and time.get_clock_info('clock') now emit a
|
|
|
DeprecationWarning warning.
|
|
|
|
|
|
- bpo-31800: Extended support for parsing UTC offsets. strptime '%z' can now
|
|
|
parse the output generated by datetime.isoformat, including seconds and
|
|
|
microseconds.
|
|
|
|
|
|
- bpo-28603: traceback: Fix a TypeError that occurred during printing of
|
|
|
exception tracebacks when either the current exception or an exception in
|
|
|
its context/cause chain is unhashable. Patch by Zane Bitter.
|

:func:`~time.clock_gettime_ns`, :func:`~time.clock_settime_ns`,
|
|
|
:func:`~time.monotonic_ns`, :func:`~time.perf_counter_ns`,
|
|
|
:func:`~time.process_time_ns`, :func:`~time.time_ns`.

|
from collections.abc rather than collections.
|
|
|
|

|
|
|
as group flags for regular expressions.
|
|
|
|
|
|
- bpo-30349: FutureWarning is now emitted if a regular expression contains
|
|
|
character set constructs that will change semantically in the future
|
|
|
(nested sets and set operations).
|
|
|
|
|
|
- bpo-31664: Added support for the Blowfish hashing in the crypt module.
|
|
|
|
|
|
- bpo-31632: Fix method set_protocol() of class _SSLProtocolTransport in

|
|
arbitrary negative timeouts on all OSes where it can only be a
|
|
|
non-negative integer or -1. Patch by Riccardo Coccioli.

|
|
|
- bpo-31705: Skip test_socket.test_sha256() on Linux kernel older than 4.5.
|
|
|
The test fails with ENOKEY on kernel 3.10 (on ppc64le). A fix was merged
|
|
|
into the kernel 4.5.
|
|
|
|
|
|
- bpo-32138: Skip on Android test_faulthandler tests that raise SIGSEGV and

|
|
|
|
|
- bpo-32136: The runtime embedding tests have been split out from
|
|
|
``Lib/test/test_capi.py`` into a new ``Lib/test/test_embed.py`` file.
|
|
|
|
|
|
- bpo-28668: test.support.requires_multiprocessing_queue is removed. Skip
|
|
|
tests with test.support.import_module('multiprocessing.synchronize')
|
|
|
instead when the semaphore implementation is broken or missing.
|
|
|
|
|
|
- bpo-32126: Skip test_get_event_loop_new_process in
|
|
|
test.test_asyncio.test_events when sem_open() is not functional.
|
|
|
|
|
|
- bpo-31174: Fix test_tools.test_unparse: DirectoryTestCase now stores the
|
|
|
names sample to always test the same files. It prevents false alarms when
|
|
|
hunting reference leaks.
|
|
|
|
|
|

|
|
|
|
|
|

|
|
|
there was more than one function and/or method in a .c file with the same
|
|
|
name.
|
|
|
|
|
|

|
|
|
|
|
|
- bpo-28791: Update OS X installer to use SQLite 3.21.0.
|
|
|
|
|
|
- bpo-28643: Record profile-opt build progress with stamp files.
|
|
|
|
|
|
- bpo-31866: Finish removing support for AtheOS.
|
|
|
|
|
|
Windows
|
|
|
-------
|
|
|
|
|
|
- bpo-1102: Return ``None`` when ``View.Fetch()`` returns
|
|
|
``ERROR_NO_MORE_ITEMS`` instead of raising ``MSIError``.
|
|
|
|
|
|
Initial patch by Anthony Tuininga.
|
|
|
|
|
|
- bpo-31944: Fixes Modify button in Apps and Features dialog.
|
|
|
|
|
|
- bpo-20486: Implement the ``Database.Close()`` method to help closing MSI
|
|
|
database objects.
|
|
|
|
|
|
- bpo-31857: Make the behavior of USE_STACKCHECK deterministic in a
|
|
|
multi-threaded environment.
|
|
|
|
|
|
macOS
|
|
|
-----
|
|
|
|
|
|
- bpo-31392: Update macOS installer to use OpenSSL 1.0.2m
|
|
|
|
|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-32207: Improve tk event exception tracebacks in IDLE. When tk event
|
|
|
handling is driven by IDLE's run loop, a confusing and distracting
|
|
|
queue.EMPTY traceback context is no longer added to tk event exception
|
|
|
tracebacks. The traceback is now the same as when event handling is
|
|
|
driven by user code. Patch based on a suggestion by Serhiy Storchaka.
|
|
|
|
|
|
- bpo-32164: Delete unused file idlelib/tabbedpages.py. Use of TabbedPageSet
|
|
|
in configdialog was replaced by ttk.Notebook.
|
|
|
|
|
|
- bpo-32100: IDLE: Fix old and new bugs in pathbrowser; improve tests. Patch
|
|
|
mostly by Cheryl Sabella.
|
|
|
|
|
|
- bpo-31858: IDLE -- Restrict shell prompt manipulation to the shell. Editor
|
|
|
and output windows only see an empty last prompt line. This simplifies
|
|
|
the code and fixes a minor bug when newline is inserted. Sys.ps1, if
|
|
|
present, is read on Shell start-up, but is not set or changed.
|
|
|
|
|
|
- bpo-31860: The font sample in the IDLE configuration dialog is now
|
|
|
editable. Changes persist while IDLE remains open
|
|
|
|
|
|
- bpo-31836: Test_code_module now passes if run after test_idle, which sets
|
|
|
ps1.
|
|
|
|
|
|
The code module uses sys.ps1 if present or sets it to '>>> ' if not.
|
|
|
Test_code_module now properly tests both behaviors. Ditto for ps2.
|
|
|
|
|
|
- bpo-28603: Fix a TypeError that caused a shell restart when printing a
|
|
|
traceback that includes an exception that is unhashable. Patch by Zane
|
|
|
Bitter.
|
|
|
|
|
|
- bpo-13802: Use non-Latin characters in the IDLE's Font settings sample.
|
|
|
Even if one selects a font that defines a limited subset of the unicode
|
|
|
Basic Multilingual Plane, tcl/tk will use other fonts that define a
|
|
|
character. The expanded example give users of non-Latin characters a
|
|
|
better idea of what they might see in IDLE's shell and editors.
|
|
|
|
|
|
To make room for the expanded sample, frames on the Font tab are
|
|
|
re-arranged. The Font/Tabs help explains a bit about the additions.
|
|
|
|
|
|
Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-32159: Remove CVS and Subversion tools: remove svneol.py and
|
|
|
treesync.py scripts. CPython migrated from CVS to Subversion, to
|
|
|
Mercurial, and then to Git. CVS and Subversion are no longer used to
|
|
|
develop CPython.
|
|
|
|
|
|
- bpo-30722: Make redemo work with Python 3.6 and newer versions.
|
|
|
|
|
|
Also, remove the ``LOCALE`` option since it doesn't work with string
|
|
|
patterns in Python 3.
|
|
|
|
|
|
Patch by Christoph Sarnowski.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-20891: Fix PyGILState_Ensure(). When PyGILState_Ensure() is called in
|
|
|
a non-Python thread before PyEval_InitThreads(), only call
|
|
|
PyEval_InitThreads() after calling PyThreadState_New() to fix a crash.
|
|
|
|
|
|
- bpo-32125: The ``Py_UseClassExceptionsFlag`` flag has been removed. It was
|
|
|
deprecated and wasn't used anymore since Python 2.0.
|
|
|
|
|
|
- bpo-25612: Move the current exception state from the frame object to the
|
|
|
co-routine. This simplifies the interpreter and fixes a couple of obscure
|
|
|
bugs caused by having swap exception state when entering or exiting a
|
|
|
generator.
|
|
|
|
|
|
- bpo-23699: Add Py_RETURN_RICHCOMPARE macro to reduce boilerplate code in
|
|
|
rich comparison functions.
|
|
|
|
|
|
- bpo-30697: The `PyExc_RecursionErrorInst` singleton is removed and
|
|
|
`PyErr_NormalizeException()` does not use it anymore. This singleton is
|
|
|
persistent and its members being never cleared may cause a segfault during
|
|
|
finalization of the interpreter. See also issue #22898.

What's New in Python 3.7.0 alpha 2?
|
|
|
===================================
|
|
|
|
|
|
*Release date: 2017-10-16*
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-31558: ``gc.freeze()`` is a new API that allows for moving all objects
|
|
|
currently tracked by the garbage collector to a permanent generation,
|
|
|
effectively removing them from future collection events. This can be used
|
|
|
to protect those objects from having their PyGC_Head mutated. In effect,
|
|
|
this enables great copy-on-write stability at fork().
|
|
|
|
|
|
- bpo-31642: Restored blocking "from package import module" by setting
|
|
|
sys.modules["package.module"] to None.
|
|
|
|
|
|
- bpo-31708: Allow use of asynchronous generator expressions in synchronous
|
|
|
functions.
|
|
|
|
|
|
- bpo-31709: Drop support of asynchronous __aiter__.
|
|
|
|
|
|
- bpo-30404: The -u option now makes the stdout and stderr streams
|
|
|
unbuffered rather than line-buffered.
|
|
|
|
|
|
- bpo-31619: Fixed a ValueError when convert a string with large number of
|
|
|
underscores to integer with binary base.
|
|
|
|
|
|
- bpo-31602: Fix an assertion failure in `zipimporter.get_source()` in case
|
|
|
of a bad `zlib.decompress()`. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31592: Fixed an assertion failure in Python parser in case of a bad
|
|
|
`unicodedata.normalize()`. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31588: Raise a `TypeError` with a helpful error message when class
|
|
|
creation fails due to a metaclass with a bad ``__prepare__()`` method.
|
|
|
Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31574: Importlib was instrumented with two dtrace probes to profile
|
|
|
import timing.
|
|
|
|
|
|
- bpo-31566: Fix an assertion failure in `_warnings.warn()` in case of a bad
|
|
|
``__name__`` global. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31506: Improved the error message logic for object.__new__ and
|
|
|
object.__init__.
|
|
|
|
|
|
- bpo-31505: Fix an assertion failure in `json`, in case
|
|
|
`_json.make_encoder()` received a bad `encoder()` argument. Patch by Oren
|
|
|
Milman.
|
|
|
|
|
|
- bpo-31492: Fix assertion failures in case of failing to import from a
|
|
|
module with a bad ``__name__`` attribute, and in case of failing to access
|
|
|
an attribute of such a module. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31478: Fix an assertion failure in `_random.Random.seed()` in case the
|
|
|
argument has a bad ``__abs__()`` method. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31336: Speed up class creation by 10-20% by reducing the overhead in
|
|
|
the necessary special method lookups. Patch by Stefan Behnel.
|
|
|
|
|
|
- bpo-31415: Add ``-X importtime`` option to show how long each import
|
|
|
takes. It can be used to optimize application's startup time. Support the
|
|
|
:envvar:`PYTHONPROFILEIMPORTTIME` as an equivalent way to enable this.
|
|
|
|
|
|
- bpo-31410: Optimized calling wrapper and classmethod descriptors.
|
|
|
|
|
|
- bpo-31353: :pep:`553` - Add a new built-in called ``breakpoint()`` which
|
|
|
calls ``sys.breakpointhook()``. By default this imports ``pdb`` and calls
|
|
|
``pdb.set_trace()``, but users may override ``sys.breakpointhook()`` to
|
|
|
call whatever debugger they want. The original value of the hook is saved
|
|
|
in ``sys.__breakpointhook__``.
|
|
|
|
|
|
- bpo-17852: Maintain a list of open buffered files, flush them before
|
|
|
exiting the interpreter. Based on a patch from Armin Rigo.
|
|
|
|
|
|
- bpo-31315: Fix an assertion failure in imp.create_dynamic(), when
|
|
|
spec.name is not a string. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31311: Fix a crash in the ``__setstate__()`` method of
|
|
|
`ctypes._CData`, in case of a bad ``__dict__``. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31293: Fix crashes in true division and multiplication of a timedelta
|
|
|
object by a float with a bad as_integer_ratio() method. Patch by Oren
|
|
|
Milman.
|
|
|
|
|
|
- bpo-31285: Fix an assertion failure in `warnings.warn_explicit`, when the
|
|
|
return value of the received loader's get_source() has a bad splitlines()
|
|
|
method. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-30406: Make ``async`` and ``await`` proper keywords, as specified in
|
|
|
PEP 492.
|
|
|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-30058: Fixed buffer overflow in select.kqueue.control().
|
|
|
|
|
|
- bpo-31672: ``idpattern`` in ``string.Template`` matched some non-ASCII
|
|
|
characters. Now it uses ``-i`` regular expression local flag to avoid
|
|
|
non-ASCII characters.
|
|
|
|
|
|
- bpo-31701: On Windows, faulthandler.enable() now ignores MSC and COM
|
|
|
exceptions.
|
|
|
|
|
|
- bpo-31728: Prevent crashes in `_elementtree` due to unsafe cleanup of
|
|
|
`Element.text` and `Element.tail`. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31671: Now ``re.compile()`` converts passed RegexFlag to normal int
|
|
|
object before compiling. bm_regex_compile benchmark shows 14% performance
|
|
|
improvements.
|
|
|
|
|
|
- bpo-30397: The types of compiled regular objects and match objects are now
|
|
|
exposed as `re.Pattern` and `re.Match`. This adds information in pydoc
|
|
|
output for the re module.
|
|
|
|
|
|
- bpo-31675: Fixed memory leaks in Tkinter's methods splitlist() and split()
|
|
|
when pass a string larger than 2 GiB.
|
|
|
|
|
|
- bpo-31673: Fixed typo in the name of Tkinter's method adderrorinfo().
|
|
|
|
|
|
- bpo-31648: Improvements to path predicates in ElementTree:
|
|
|
|
|
|
* Allow whitespace around predicate parts, i.e. "[a = 'text']" instead of requiring the less readable "[a='text']".
|
|
|
* Add support for text comparison of the current node, like "[.='text']".
|
|
|
|
|
|
Patch by Stefan Behnel.
|
|
|
|
|
|
- bpo-30806: Fix the string representation of a netrc object.
|
|
|
|
|
|
- bpo-31638: Add optional argument ``compressed`` to
|
|
|
``zipapp.create_archive``, and add option ``--compress`` to the command
|
|
|
line interface of ``zipapp``.
|
|
|
|
|
|
- bpo-25351: Avoid venv activate failures with undefined variables
|
|
|
|
|
|
- bpo-20519: Avoid ctypes use (if possible) and improve import time for
|
|
|
uuid.
|
|
|
|
|
|
- bpo-28293: The regular expression cache is no longer completely dumped
|
|
|
when it is full.
|
|
|
|
|
|
- bpo-31596: Added pthread_getcpuclockid() to the time module
|
|
|
|
|
|
- bpo-27494: Make 2to3 accept a trailing comma in generator expressions. For
|
|
|
example, ``set(x for x in [],)`` is now allowed.
|
|
|
|
|
|
- bpo-30347: Stop crashes when concurrently iterate over itertools.groupby()
|
|
|
iterators.
|
|
|
|
|
|
- bpo-30346: An iterator produced by itertools.groupby() iterator now
|
|
|
becomes exhausted after advancing the groupby iterator.
|
|
|
|
|
|
- bpo-31556: Cancel asyncio.wait_for future faster if timeout <= 0
|
|
|
|
|
|
- bpo-31540: Allow passing a context object in
|
|
|
:class:`concurrent.futures.ProcessPoolExecutor` constructor. Also, free
|
|
|
job resources in :class:`concurrent.futures.ProcessPoolExecutor` earlier
|
|
|
to improve memory usage when a worker waits for new jobs.
|
|
|
|
|
|
- bpo-31516: ``threading.current_thread()`` should not return a dummy thread
|
|
|
at shutdown.
|
|
|
|
|
|
- bpo-31525: In the sqlite module, require the sqlite3_prepare_v2 API. Thus,
|
|
|
the sqlite module now requires sqlite version at least 3.3.9.
|
|
|
|
|
|
- bpo-26510: argparse subparsers are now required by default. This matches
|
|
|
behaviour in Python 2. For optional subparsers, use the new parameter
|
|
|
``add_subparsers(required=False)``. Patch by Anthony Sottile. (As of
|
|
|
3.7.0rc1, the default was changed to not required as had been the case
|
|
|
since Python 3.3.)
|
|
|
|
|
|
- bpo-27541: Reprs of subclasses of some collection and iterator classes
|
|
|
(`bytearray`, `array.array`, `collections.deque`,
|
|
|
`collections.defaultdict`, `itertools.count`, `itertools.repeat`) now
|
|
|
contain actual type name insteads of hardcoded name of the base class.
|
|
|
|
|
|
- bpo-31351: python -m ensurepip now exits with non-zero exit code if pip
|
|
|
bootstrapping has failed.
|
|
|
|
|
|
- bpo-31389: ``pdb.set_trace()`` now takes an optional keyword-only argument
|
|
|
``header``. If given, this is printed to the console just before debugging
|
|
|
begins.
|
|
|
|
|
|
Documentation
|
|
|
-------------
|
|
|
|
|
|
- bpo-31537: Fix incorrect usage of ``get_history_length`` in readline
|
|
|
documentation example code. Patch by Brad Smith.
|
|
|
|
|
|
- bpo-30085: The operator functions without double underscores are preferred
|
|
|
for clarity. The one with underscores are only kept for
|
|
|
back-compatibility.
|
|
|
|
|
|
Build
|
|
|
-----
|
|
|
|
|
|
- bpo-31696: Improve compiler version information in :data:`sys.version`
|
|
|
when Python is built with Clang.
|
|
|
|
|
|
- bpo-31625: Stop using ranlib on static libraries. Instead, we assume ar
|
|
|
supports the 's' flag.
|
|
|
|
|
|
- bpo-31624: Remove support for BSD/OS.
|
|
|
|
|
|
- bpo-22140: Prevent double substitution of prefix in python-config.sh.
|
|
|
|
|
|
- bpo-31569: Correct PCBuild/ case to PCbuild/ in build scripts and
|
|
|
documentation.
|
|
|
|
|
|
- bpo-31536: Avoid wholesale rebuild after `make regen-all` if nothing
|
|
|
changed.
|
|
|
|
|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-31460: Simplify the API of IDLE's Module Browser.
|
|
|
|
|
|
Passing a widget instead of an flist with a root widget opens the option
|
|
|
of creating a browser frame that is only part of a window. Passing a full
|
|
|
file name instead of pieces assumed to come from a .py file opens the
|
|
|
possibility of browsing python files that do not end in .py.
|
|
|
|
|
|
- bpo-31649: IDLE - Make _htest, _utest parameters keyword only.
|
|
|
|
|
|
- bpo-31559: Remove test order dependence in idle_test.test_browser.
|
|
|
|
|
|
- bpo-31459: Rename IDLE's module browser from Class Browser to Module
|
|
|
Browser. The original module-level class and method browser became a
|
|
|
module browser, with the addition of module-level functions, years ago.
|
|
|
Nested classes and functions were added yesterday. For
|
|
|
back-compatibility, the virtual event <<open-class-browser>>, which
|
|
|
appears on the Keys tab of the Settings dialog, is not changed. Patch by
|
|
|
Cheryl Sabella.
|
|
|
|
|
|
- bpo-31500: Default fonts now are scaled on HiDPI displays.
|
|
|
|
|
|
- bpo-1612262: IDLE module browser now shows nested classes and functions.
|
|
|
Original patches for code and tests by Guilherme Polo and Cheryl Sabella,
|
|
|
respectively.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-28280: Make `PyMapping_Keys()`, `PyMapping_Values()` and
|
|
|
`PyMapping_Items()` always return a `list` (rather than a `list` or a
|
|
|
`tuple`). Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31532: Fix memory corruption due to allocator mix in getpath.c between
|
|
|
Py_GetPath() and Py_SetPath()
|
|
|
|
|
|
- bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API: it is
|
|
|
a new Thread Local Storage (TLS) API to CPython which would supersede use
|
|
|
of the existing TLS API within the CPython interpreter, while deprecating
|
|
|
the existing API. PEP written by Erik M. Bray, patch by Masayuki Yamamoto.

|
|
|
|
*Release date: 2017-09-19*
|
|
|
|
|
|
Security
|
|
|
--------
|

|
|
|
over BIO has not been performed yet.
|
|
|
|
|
|
- bpo-29505: Add fuzz tests for float(str), int(str), unicode(str); for
|
|
|
oss-fuzz.
|
|
|
|
|
|
- bpo-30947: Upgrade libexpat embedded copy from version 2.2.1 to 2.2.3 to
|
|
|
get security fixes.
|
|
|
|
|
|
- bpo-30730: Prevent environment variables injection in subprocess on
|
|
|
Windows. Prevent passing other environment variables and command
|
|
|
arguments.
|
|
|
|
|
|
- bpo-30694: Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes of multiple
|

Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-31490: Fix an assertion failure in `ctypes` class definition, in case
|
|
|
the class has an attribute whose name is specified in ``_anonymous_`` but
|
|
|
not in ``_fields_``. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31471: Fix an assertion failure in `subprocess.Popen()` on Windows, in
|
|
|
case the env argument has a bad keys() method. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31418: Fix an assertion failure in `PyErr_WriteUnraisable()` in case
|
|
|
of an exception with a bad ``__module__`` attribute. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31416: Fix assertion failures in case of a bad warnings.filters or
|
|
|
warnings.defaultaction. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-28411: Change direct usage of PyInterpreterState.modules to
|
|
|
PyImport_GetModuleDict(). Also introduce more uniformity in other code
|
|
|
that deals with sys.modules. This helps reduce complications when working
|
|
|
on sys.modules.
|
|
|
|
|
|
- bpo-28411: Switch to the abstract API when dealing with
|
|
|
``PyInterpreterState.modules``. This allows later support for all dict
|
|
|
subclasses and other Mapping implementations. Also add a
|
|
|
``PyImport_GetModule()`` function to reduce a bunch of duplicated code.
|
|
|
|
|
|
- bpo-31411: Raise a TypeError instead of SystemError in case
|
|
|
warnings.onceregistry is not a dictionary. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31344: For finer control of tracing behaviour when testing the
|
|
|
interpreter, two new frame attributes have been added to control the
|
|
|
emission of particular trace events: ``f_trace_lines`` (``True`` by
|
|
|
default) to turn off per-line trace events; and ``f_trace_opcodes``
|
|
|
(``False`` by default) to turn on per-opcode trace events.
|
|
|
|
|
|
- bpo-31373: Fix several possible instances of undefined behavior due to
|
|
|
floating-point demotions.
|
|
|
|
|
|
- bpo-30465: Location information (``lineno`` and ``col_offset``) in
|
|
|
f-strings is now (mostly) correct. This fixes tools like flake8 from
|
|
|
showing warnings on the wrong line (typically the first line of the file).
|
|
|
|
|
|
- bpo-30860: Consolidate CPython's global runtime state under a single
|
|
|
struct. This improves discoverability of the runtime state.
|
|
|
|
|
|
- bpo-31347: Fix possible undefined behavior in _PyObject_FastCall_Prepend.
|
|
|
|
|
|
- bpo-31343: Include sys/sysmacros.h for major(), minor(), and makedev().
|
|
|
GNU C libray plans to remove the functions from sys/types.h.
|
|
|
|
|
|
- bpo-31291: Fix an assertion failure in `zipimport.zipimporter.get_data` on
|
|
|
Windows, when the return value of ``pathname.replace('/','\\')`` isn't a
|
|
|
string. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31271: Fix an assertion failure in the write() method of
|
|
|
`io.TextIOWrapper`, when the encoder doesn't return a bytes object. Patch
|
|
|
by Oren Milman.
|
|
|
|
|
|
- bpo-31243: Fix a crash in some methods of `io.TextIOWrapper`, when the
|
|
|
decoder's state is invalid. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-30721: ``print`` now shows correct usage hint for using Python 2
|
|
|
redirection syntax. Patch by Sanyam Khurana.
|
|
|
|
|
|
- bpo-31070: Fix a race condition in importlib _get_module_lock().
|
|
|
|
|
|
- bpo-30747: Add a non-dummy implementation of _Py_atomic_store and
|
|
|
_Py_atomic_load on MSVC.
|
|
|
|
|
|
- bpo-31095: Fix potential crash during GC caused by ``tp_dealloc`` which
|
|
|
doesn't call ``PyObject_GC_UnTrack()``.
|
|
|
|
|
|
- bpo-31071: Avoid masking original TypeError in call with * unpacking when
|
|
|
other arguments are passed.
|
|
|
|
|
|
- bpo-30978: str.format_map() now passes key lookup exceptions through.
|
|
|
Previously any exception was replaced with a KeyError exception.
|
|
|
|
|
|
- bpo-30808: Use _Py_atomic API for concurrency-sensitive signal state.
|
|
|
|
|
|
- bpo-30876: Relative import from unloaded package now reimports the package
|
|
|
instead of failing with SystemError. Relative import from non-package now
|
|
|
fails with ImportError rather than SystemError.
|
|
|
|
|
|
- bpo-30703: Improve signal delivery.
|
|
|
|
|
|
Avoid using Py_AddPendingCall from signal handler, to avoid calling
|
|
|
signal-unsafe functions. The tests I'm adding here fail without the rest
|
|
|
of the patch, on Linux and OS X. This means our signal delivery logic had
|
|
|
defects (some signals could be lost).
|
|
|
|
|
|
- bpo-30765: Avoid blocking in pthread_mutex_lock() when
|
|
|
PyThread_acquire_lock() is asked not to block.
|
|
|
|
|
|
- bpo-31161: Make sure the 'Missing parentheses' syntax error message is
|
|
|
only applied to SyntaxError, not to subclasses. Patch by Martijn Pieters.
|
|
|
|
|
|
- bpo-30814: Fixed a race condition when import a submodule from a package.
|
|
|
|
|
|
- bpo-30736: The internal unicodedata database has been upgraded to Unicode
|
|
|
10.0.
|
|
|
|
|
|
- bpo-30604: Move co_extra_freefuncs from per-thread to per-interpreter to
|
|
|
avoid crashes.
|
|
|
|
|
|
- bpo-30597: ``print`` now shows expected input in custom error message when
|
|
|
used as a Python 2 statement. Patch by Sanyam Khurana.
|
|
|
|
|
|
- bpo-30682: Removed a too-strict assertion that failed for certain
|
|
|
f-strings, such as eval("f'\\\n'") and eval("f'\\\r'").
|
|
|
|
|
|
- bpo-30501: The compiler now produces more optimal code for complex
|
|
|
condition expressions in the "if", "while" and "assert" statement, the
|
|
|
"if" expression, and generator expressions and comprehensions.
|
|
|
|
|
|
- bpo-28180: Implement PEP 538 (legacy C locale coercion). This means that
|
|
|
when a suitable coercion target locale is available, both the core
|
|
|
interpreter and locale-aware C extensions will assume the use of UTF-8 as
|
|
|
the default text encoding, rather than ASCII.
|
|
|
|
|
|
- bpo-30486: Allows setting cell values for __closure__. Patch by Lisa
|
|
|
Roach.
|
|
|
|
|
|
- bpo-30537: itertools.islice now accepts integer-like objects (having an
|
|
|
__index__ method) as start, stop, and slice arguments
|
|
|
|
|
|
- bpo-25324: Tokens needed for parsing in Python moved to C. ``COMMENT``,
|
|
|
``NL`` and ``ENCODING``. This way the tokens and tok_names in the token
|
|
|
module don't get changed when you import the tokenize module.
|
|
|
|
|
|
- bpo-29104: Fixed parsing backslashes in f-strings.
|
|
|
|
|
|
- bpo-27945: Fixed various segfaults with dict when input collections are
|
|
|
mutated during searching, inserting or comparing. Based on patches by
|
|
|
Duane Griffin and Tim Mitchell.
|
|
|
|
|
|
- bpo-25794: Fixed type.__setattr__() and type.__delattr__() for
|
|
|
non-interned attribute names. Based on patch by Eryk Sun.
|
|
|
|
|
|
- bpo-30039: If a KeyboardInterrupt happens when the interpreter is in the
|
|
|
middle of resuming a chain of nested 'yield from' or 'await' calls, it's
|
|
|
now correctly delivered to the innermost frame.
|
|
|
|
|
|
- bpo-28974: ``object.__format__(x, '')`` is now equivalent to ``str(x)``
|
|
|
rather than ``format(str(self), '')``.
|
|
|
|
|
|
- bpo-30024: Circular imports involving absolute imports with binding a
|
|
|
submodule to a name are now supported.
|
|
|
|
|
|
- bpo-12414: sys.getsizeof() on a code object now returns the sizes which
|
|
|
includes the code struct and sizes of objects which it references. Patch
|
|
|
by Dong-hee Na.
|
|
|
|
|
|
- bpo-29839: len() now raises ValueError rather than OverflowError if
|
|
|
__len__() returned a large negative integer.
|
|
|
|
|
|
- bpo-11913: README.rst is now included in the list of distutils standard
|
|
|
READMEs and therefore included in source distributions.
|
|
|
|
|
|
- bpo-29914: Fixed default implementations of __reduce__ and
|
|
|
__reduce_ex__(). object.__reduce__() no longer takes arguments,
|
|
|
object.__reduce_ex__() now requires one argument.
|
|
|
|
|
|
- bpo-29949: Fix memory usage regression of set and frozenset object.
|
|
|
|
|
|
- bpo-29935: Fixed error messages in the index() method of tuple, list and
|
|
|
deque when pass indices of wrong type.
|
|
|
|
|
|
- bpo-29816: Shift operation now has less opportunity to raise
|
|
|
OverflowError. ValueError always is raised rather than OverflowError for
|
|
|
negative counts. Shifting zero with non-negative count always returns
|
|
|
zero.
|
|
|
|
|
|
- bpo-24821: Fixed the slowing down to 25 times in the searching of some
|
|
|
unlucky Unicode characters.
|
|
|
|
|
|
- bpo-29102: Add a unique ID to PyInterpreterState. This makes it easier to
|
|
|
identify each subinterpreter.
|
|
|
|
|
|
- bpo-29894: The deprecation warning is emitted if __complex__ returns an
|
|
|
instance of a strict subclass of complex. In a future versions of Python
|
|
|
this can be an error.
|
|
|
|
|
|
- bpo-29859: Show correct error messages when any of the pthread_* calls in
|
|
|
thread_pthread.h fails.
|
|
|
|
|
|
- bpo-29849: Fix a memory leak when an ImportError is raised during from
|
|
|
import.
|
|
|
|
|
|
- bpo-28856: Fix an oversight that %b format for bytes should support
|
|
|
objects follow the buffer protocol.
|
|
|
|
|
|
- bpo-29723: The ``sys.path[0]`` initialization change for bpo-29139 caused
|
|
|
a regression by revealing an inconsistency in how sys.path is initialized
|
|
|
when executing ``__main__`` from a zipfile, directory, or other import
|
|
|
location. The interpreter now consistently avoids ever adding the import
|
|
|
location's parent directory to ``sys.path``, and ensures no other
|
|
|
``sys.path`` entries are inadvertently modified when inserting the import
|
|
|
location named on the command line.
|
|
|
|
|
|
- bpo-29568: Escaped percent "%%" in the format string for classic string
|
|
|
formatting no longer allows any characters between two percents.
|
|
|
|
|
|
- bpo-29714: Fix a regression that bytes format may fail when containing
|
|
|
zero bytes inside.
|
|
|
|
|
|
- bpo-29695: bool(), float(), list() and tuple() no longer take keyword
|
|
|
arguments. The first argument of int() can now be passes only as
|
|
|
positional argument.
|
|
|
|
|
|
- bpo-28893: Set correct __cause__ for errors about invalid awaitables
|
|
|
returned from __aiter__ and __anext__.
|
|
|
|
|
|
- bpo-28876: ``bool(range)`` works even if ``len(range)`` raises
|
|
|
:exc:`OverflowError`.
|
|
|
|
|
|
- bpo-29683: Fixes to memory allocation in _PyCode_SetExtra. Patch by Brian
|
|
|
Coleman.
|
|
|
|
|
|
- bpo-29684: Fix minor regression of PyEval_CallObjectWithKeywords. It
|
|
|
should raise TypeError when kwargs is not a dict. But it might cause segv
|
|
|
when args=NULL and kwargs is not a dict.
|
|
|
|
|
|
- bpo-28598: Support __rmod__ for subclasses of str being called before
|
|
|
str.__mod__. Patch by Martijn Pieters.
|
|
|
|
|
|
- bpo-29607: Fix stack_effect computation for CALL_FUNCTION_EX. Patch by
|
|
|
Matthieu Dartiailh.
|
|
|
|
|
|
- bpo-29602: Fix incorrect handling of signed zeros in complex constructor
|
|
|
for complex subclasses and for inputs having a __complex__ method. Patch
|
|
|
by Serhiy Storchaka.
|
|
|
|
|
|
- bpo-29347: Fixed possibly dereferencing undefined pointers when creating
|
|
|
weakref objects.
|
|
|
|
|
|
- bpo-29463: Add ``docstring`` field to Module, ClassDef, FunctionDef, and
|
|
|
AsyncFunctionDef ast nodes. docstring is not first stmt in their body
|
|
|
anymore. It affects ``co_firstlineno`` and ``co_lnotab`` of code object
|
|
|
for module and class. (Reverted in :issue:`32911`.)
|
|
|
|
|
|
- bpo-29438: Fixed use-after-free problem in key sharing dict.
|
|
|
|
|
|
- bpo-29546: Set the 'path' and 'name' attribute on ImportError for ``from
|
|
|
... import ...``.
|
|
|
|
|
|
- bpo-29546: Improve from-import error message with location
|
|
|
|
|
|
- bpo-29478: If max_line_length=None is specified while using the Compat32
|
|
|
policy, it is no longer ignored. Patch by Mircea Cosbuc.
|
|
|
|
|
|
- bpo-29319: Prevent RunMainFromImporter overwriting sys.path[0].
|
|
|
|
|
|
- bpo-29337: Fixed possible BytesWarning when compare the code objects.
|
|
|
Warnings could be emitted at compile time.
|
|
|
|
|
|
- bpo-29327: Fixed a crash when pass the iterable keyword argument to
|
|
|
sorted().
|
|
|
|
|
|
- bpo-29034: Fix memory leak and use-after-free in os module
|
|
|
(path_converter).
|
|
|
|
|
|
- bpo-29159: Fix regression in bytes(x) when x.__index__() raises Exception.
|
|
|
|
|
|
- bpo-29049: Call _PyObject_GC_TRACK() lazily when calling Python function.
|
|
|
Calling function is up to 5% faster.
|
|
|
|
|
|
- bpo-28927: bytes.fromhex() and bytearray.fromhex() now ignore all ASCII
|
|
|
whitespace, not only spaces. Patch by Robert Xiao.
|
|
|
|
|
|
- bpo-28932: Do not include <sys/random.h> if it does not exist.
|
|
|
|
|
|
- bpo-25677: Correct the positioning of the syntax error caret for indented
|
|
|
blocks. Based on patch by Michael Layzell.
|
|
|

|
|
- bpo-29000: Fixed bytes formatting of octals with zero padding in alternate
|
|
|
form.
|
|
|
|
|
|
- bpo-18896: Python function can now have more than 255 parameters.
|
|
|
collections.namedtuple() now supports tuples with more than 255 elements.
|
|
|
|
|
|
- bpo-28596: The preferred encoding is UTF-8 on Android. Patch written by
|
|
|
Chi Hsuan Yen.
|
|
|
|
|
|
- bpo-22257: Clean up interpreter startup (see PEP 432).
|
|
|
|
|
|
- bpo-26919: On Android, operating system data is now always encoded/decoded
|
|
|
to/from UTF-8, instead of the locale encoding to avoid inconsistencies
|
|
|
with os.fsencode() and os.fsdecode() which are already using UTF-8.
|
|
|
|
|
|
- bpo-28991: functools.lru_cache() was susceptible to an obscure reentrancy
|
|
|
bug triggerable by a monkey-patched len() function.
|
|
|
|
|
|
- bpo-28147: Fix a memory leak in split-table dictionaries: setattr() must
|
|
|
not convert combined table into split table. Patch written by INADA Naoki.
|
|
|
|
|
|
- bpo-28739: f-string expressions are no longer accepted as docstrings and
|
|
|
by ast.literal_eval() even if they do not include expressions.
|
|
|
|
|
|
- bpo-28512: Fixed setting the offset attribute of SyntaxError by
|
|
|
PyErr_SyntaxLocationEx() and PyErr_SyntaxLocationObject().
|
|
|
|
|
|
- bpo-28918: Fix the cross compilation of xxlimited when Python has been
|
|
|
built with Py_DEBUG defined.
|
|
|
|
|
|
- bpo-23722: Rather than silently producing a class that doesn't support
|
|
|
zero-argument ``super()`` in methods, failing to pass the new
|
|
|
``__classcell__`` namespace entry up to ``type.__new__`` now results in a
|
|
|
``DeprecationWarning`` and a class that supports zero-argument
|
|
|
``super()``.
|
|
|
|
|
|
- bpo-28797: Modifying the class __dict__ inside the __set_name__ method of
|
|
|
a descriptor that is used inside that class no longer prevents calling the
|
|
|
__set_name__ method of other descriptors.
|
|
|
|
|
|
- bpo-28799: Remove the ``PyEval_GetCallStats()`` function and deprecate the
|
|
|
untested and undocumented ``sys.callstats()`` function. Remove the
|
|
|
``CALL_PROFILE`` special build: use the :func:`sys.setprofile` function,
|
|
|
:mod:`cProfile` or :mod:`profile` to profile function calls.
|
|
|
|
|
|
- bpo-12844: More than 255 arguments can now be passed to a function.
|
|
|
|
|
|
- bpo-28782: Fix a bug in the implementation ``yield from`` when checking if
|
|
|
the next instruction is YIELD_FROM. Regression introduced by WORDCODE
|
|
|
(issue #26647).
|
|
|
|
|
|
- bpo-28774: Fix error position of the unicode error in ASCII and Latin1
|
|
|
encoders when a string returned by the error handler contains multiple
|
|
|
non-encodable characters (non-ASCII for the ASCII codec, characters out of
|
|
|
the U+0000-U+00FF range for Latin1).
|
|
|
|
|
|
- bpo-28731: Optimize _PyDict_NewPresized() to create correct size dict.
|
|
|
Improve speed of dict literal with constant keys up to 30%.
|
|
|
|
|
|
- bpo-28532: Show sys.version when -V option is supplied twice.
|
|
|
|
|
|
- bpo-27100: The with-statement now checks for __enter__ before it checks
|
|
|
for __exit__. This gives less confusing error messages when both methods
|
|
|
are missing. Patch by Jonathan Ellington.
|
|
|
|
|
|
- bpo-28746: Fix the set_inheritable() file descriptor method on platforms
|
|
|
that do not have the ioctl FIOCLEX and FIONCLEX commands.
|
|
|
|
|
|
- bpo-26920: Fix not getting the locale's charset upon initializing the

|
interpreter, on platforms that do not have langinfo.
|
|
|
|
|
|
- bpo-28648: Fixed crash in Py_DecodeLocale() in debug build on Mac OS X
|
|
|
when decode astral characters. Patch by Xiang Zhang.
|
|
|
|
|
|
- bpo-28665: Improve speed of the STORE_DEREF opcode by 40%.
|
|
|
|
|
|
- bpo-19398: Extra slash no longer added to sys.path components in case of
|
|
|
empty compile-time PYTHONPATH components.
|
|
|
|

|
|
- bpo-28638: Changed the implementation strategy for
|
|
|
collections.namedtuple() to substantially reduce the use of exec() in
|
|
|
favor of precomputed methods. As a result, the *verbose* parameter and
|
|
|
*_source* attribute are no longer supported. The benefits include 1)
|
|
|
having a smaller memory footprint for applications using multiple named
|
|
|
tuples, 2) faster creation of the named tuple class (approx 4x to 6x
|
|
|
depending on how it is measured), and 3) minor speed-ups for instance
|
|
|
creation using __new__, _make, and _replace. (The primary patch
|
|

contributor is Jelle Zijlstra with further improvements by INADA Naoki,
|

information about the error.
|
|
|
|
|

``idpattern``.
|
|
|
|
|
|
- bpo-31326: concurrent.futures.ProcessPoolExecutor.shutdown() now

|
|
|
|
|
|
- bpo-31249: concurrent.futures: WorkItem.run() used by ThreadPoolExecutor

now breaks a reference cycle between an exception object and the WorkItem
|
|
|
object.
|
|
|
|
|
|

|
|
|
- bpo-23835: configparser: reading defaults in the ``ConfigParser()``
|
|
|
constructor is now using ``read_dict()``, making its behavior consistent
|
|
|
with the rest of the parser. Non-string keys and values in the defaults
|
|
|
dictionary are now being implicitly converted to strings. Patch by James
|
|
|
Tocknell.
|
|
|
|
|
|
- bpo-31238: pydoc: the stop() method of the private ServerThread class now
|
|

|
|
sets its docserver attribute to None to break a reference cycle.
|
|
|
|
|

|
|
|
|
|
- bpo-31109: Convert zipimport to use Argument Clinic.
|
|
|
|
|
|
- bpo-30102: The ssl and hashlib modules now call
|
|
|
OPENSSL_add_all_algorithms_noconf() on OpenSSL < 1.1.0. The function
|
|
|
detects CPU features and enables optimizations on some CPU architectures
|
|
|
such as POWER8. Patch is based on research from Gustavo Serra Scalet.
|
|
|
|
|
|
- bpo-18966: Non-daemonic threads created by a multiprocessing.Process are

- bpo-31183: `dis` now works with asynchronous generator and coroutine
|
|
|
objects. Patch by George Collins based on diagnosis by Luciano Ramalho.
|
|
|
|
|
|
- bpo-5001: There are a number of uninformative asserts in the
|
|
|
`multiprocessing` module, as noted in issue 5001. This change fixes two of
|
|
|
the most potentially problematic ones, since they are in error-reporting
|
|
|
code, in the `multiprocessing.managers.convert_to_error` function. (It
|
|
|
also makes more informative a ValueError message.) The only potentially
|
|
|
problematic change is that the AssertionError is now a TypeError; however,
|
|
|
this should also help distinguish it from an AssertionError being
|
|
|
*reported* by the function/its caller (such as in issue 31169). - Patch by
|
|
|
Allen W. Smith (drallensmith on github).

|
- bpo-31185: Fixed miscellaneous errors in asyncio speedup module.
|
|

|
|
|
faster when comparing arrays holding values of the same integer type.
|
|
|
|
|
|
- bpo-31135: ttk: fix the destroy() method of LabeledScale and OptionMenu
|
|
|
classes. Call the parent destroy() method even if the used attribute
|
|
|
doesn't exist. The LabeledScale.destroy() method now also explicitly
|
|
|
clears label and scale attributes to help the garbage collector to destroy
|
|
|
all widgets.
|
|
|
|
|
|
- bpo-31107: Fix `copyreg._slotnames()` mangled attribute calculation for
|
|
|
classes whose name begins with an underscore. Patch by Shane Harvey.

|
|
|
|
- bpo-31080: Allow `logging.config.fileConfig` to accept kwargs and/or args.
|
|
|
|
|
|
- bpo-30897: ``pathlib.Path`` objects now include an ``is_mount()`` method
|
|
|
(only implemented on POSIX). This is similar to ``os.path.ismount(p)``.
|
|
|
Patch by Cooper Ry Lees.
|
|
|
|
|
|
- bpo-31061: Fixed a crash when using asyncio and threads.

|
|
Heimes.

|
|

|
|
|
- bpo-30919: Fix shared memory performance regression in multiprocessing in
|
|
|
3.x.
|
|
|
|
|
|
Shared memory used anonymous memory mappings in 2.x, while 3.x mmaps
|
|
|
actual files. Try to be careful to do as little disk I/O as possible.
|
|
|
|
|
|
- bpo-26732: Fix too many fds in processes started with the "forkserver"
|
|
|
method.
|
|
|
|
|
|
A child process would inherit as many fds as the number of still-running
|

|
children.

|
|
|
readline is older than 2.1 or where select() is not available.
|
|
|
|
|
|
- bpo-25684: Change ``ttk.OptionMenu`` radiobuttons to be unique across
|
|
|
instances of ``OptionMenu``.
|
|
|
|
|
|
- bpo-30886: Fix multiprocessing.Queue.join_thread(): it now waits until the
|
|
|
thread completes, even if the thread was started by the same process which
|
|
|
created the queue.
|
|
|
|
|
|

- bpo-30302: Use keywords in the ``repr`` of ``datetime.timedelta``.
|
|
|
|
|
|
- bpo-30807: signal.setitimer() may disable the timer when passed a tiny
|
|
|
value.
|
|
|
|
|
|
Tiny values (such as 1e-6) are valid non-zero values for setitimer(),
|
|
|
which is specified as taking microsecond-resolution intervals. However, on
|
|
|
some platform, our conversion routine could convert 1e-6 into a zero
|
|
|
interval, therefore disabling the timer instead of (re-)scheduling it.
|
|
|
|
|
|
- bpo-30441: Fix bug when modifying os.environ while iterating over it
|
|
|
|
|
|
- bpo-29585: Avoid importing ``sysconfig`` from ``site`` to improve startup
|
|

speed. Python startup is about 5% faster on Linux and 30% faster on macOS.
|
|
|
|
|
|
- bpo-29293: Add missing parameter "n" on
|
|
|
multiprocessing.Condition.notify().
|
|
|
|
|
|
The doc claims multiprocessing.Condition behaves like threading.Condition,
|
|
|
but its notify() method lacked the optional "n" argument (to specify the
|
|
|
number of sleepers to wake up) that threading.Condition.notify() accepts.

- bpo-29212: Fix concurrent.futures.thread.ThreadPoolExecutor threads to
|
|
|
have a non repr() based thread name by default when no thread_name_prefix

is supplied. They will now identify themselves as
|

|
- bpo-30176: Add missing attribute related constants in curses
|
|
|
documentation.
|
|
|
|
|
|
- bpo-30052: the link targets for :func:`bytes` and :func:`bytearray` are
|
|
|
now their respective type definitions, rather than the corresponding
|
|
|
builtin function entries. Use :ref:`bytes <func-bytes>` and
|
|
|
:ref:`bytearray <func-bytearray>` to reference the latter.
|
|
|
|
|
|
In order to ensure this and future cross-reference updates are applied
|
|
|
automatically, the daily documentation builds now disable the default
|
|
|
output caching features in Sphinx.

Tests
|
|
|
-----
|
|
|
|
|
|
- bpo-29639: test.support.HOST is now "localhost", a new HOSTv4 constant has
|
|
|
been added for your ``127.0.0.1`` needs, similar to the existing HOSTv6
|
|
|
constant.
|
|
|
|
|
|
- bpo-31320: Silence traceback in test_ssl
|
|
|
|
|
|
- bpo-31346: Prefer PROTOCOL_TLS_CLIENT and PROTOCOL_TLS_SERVER protocols
|
|
|
for SSLContext.
|
|
|
|
|
|
- bpo-25674: Remove sha256.tbs-internet.com ssl test
|
|
|
|
|
|
- bpo-30715: Address ALPN callback changes for OpenSSL 1.1.0f. The latest
|
|
|
version behaves like OpenSSL 1.0.2 and no longer aborts handshake.
|
|
|
|
|
|
- bpo-30822: regrtest: Exclude tzdata from regrtest --all. When running the
|
|
|
test suite using --use=all / -u all, exclude tzdata since it makes
|
|
|
test_datetime too slow (15-20 min on some buildbots) which then times out
|
|
|
on some buildbots. Fix also regrtest command line parser to allow passing
|
|
|
-u extralargefile to run test_zipfile64.
|
|
|
|
|
|
- bpo-30695: Add the `set_nomemory(start, stop)` and `remove_mem_hooks()`
|
|
|
functions to the _testcapi module.
|
|
|
|
|
|
- bpo-30357: test_thread: setUp() now uses support.threading_setup() and
|
|
|
support.threading_cleanup() to wait until threads complete to avoid random
|
|
|
side effects on following tests. Initial patch written by Grzegorz
|
|
|
Grzywacz.
|
|
|
|
|
|
- bpo-30197: Enhanced functions swap_attr() and swap_item() in the
|
|
|
test.support module. They now work when delete replaced attribute or item
|
|
|
inside the with statement. The old value of the attribute or item (or
|
|
|
None if it doesn't exist) now will be assigned to the target of the "as"
|
|
|
clause, if there is one.
|
|
|
|
|
|
- bpo-24932: Use proper command line parsing in _testembed
|
|
|
|
|
|
- bpo-28950: Disallow -j0 to be combined with -T/-l in regrtest command line
|
|
|
arguments.
|
|
|
|
|
|
- bpo-28683: Fix the tests that bind() a unix socket and raise
|
|
|
PermissionError on Android for a non-root user.
|
|
|
|
|
|
- bpo-26936: Fix the test_socket failures on Android - getservbyname(),
|
|
|
getservbyport() and getaddrinfo() are broken on some Android API levels.
|
|
|
|
|
|
- bpo-28666: Now test.support.rmtree is able to remove unwritable or
|
|
|
unreadable directories.
|
|
|
|
|
|
- bpo-23839: Various caches now are cleared before running every test file.
|
|
|
|
|
|
- bpo-26944: Fix test_posix for Android where 'id -G' is entirely wrong or
|
|
|
missing the effective gid.
|
|
|
|
|
|
- bpo-28409: regrtest: fix the parser of command line arguments.
|
|
|
|
|
|
- bpo-28217: Adds _testconsole module to test console input.
|
|
|
|
|
|
- bpo-26939: Add the support.setswitchinterval() function to fix
|
|
|
test_functools hanging on the Android armv7 qemu emulator.
|
|
|
|
|
|
Build
|
|
|
-----
|
|
|
|
|
|
- bpo-31354: Allow --with-lto to be used on all builds, not just `make
|
|
|
profile-opt`.
|
|
|
|
|
|
- bpo-31370: Remove support for building --without-threads.
|
|
|
|
|
|
This option is not really useful anymore in the 21st century. Removing
|
|
|
lots of conditional paths allows us to simplify the code base, including
|
|
|
in difficult to maintain low-level internal code.
|
|
|
|

|
|
|
|
|
|
- bpo-29941: Add ``--with-assertions`` configure flag to explicitly enable C
|
|
|
``assert()`` checks. Defaults to off. ``--with-pydebug`` implies
|
|
|
``--with-assertions``.
|
|
|
|
|

|
``--enable-optimizations``.
|
|
|
|
|
|
- bpo-23404: Don't regenerate generated files based on file modification
|
|
|
time anymore: the action is now explicit. Replace ``make touch`` with
|
|
|
``make regen-all``.
|
|
|
|
|
|
- bpo-29643: Fix ``--enable-optimization`` didn't work.
|
|
|
|
|
|
- bpo-27593: sys.version and the platform module python_build(),
|
|
|
python_branch(), and python_revision() functions now use git information
|
|
|
rather than hg when building from a repo.
|
|
|
|
|
|
- bpo-29572: Update Windows build and OS X installers to use OpenSSL 1.0.2k.
|
|
|
|
|
|
- bpo-27659: Prohibit implicit C function declarations: use
|
|
|
``-Werror=implicit-function-declaration`` when possible (GCC and Clang,
|
|
|
but it depends on the compiler version). Patch written by Chi Hsuan Yen.
|
|
|
|
|
|
- bpo-29384: Remove old Be OS helper scripts.
|
|
|
|
|

|
defined.
|
|
|

Segev Finer.
|
|
|
|
|
|
- bpo-30450: The build process on Windows no longer depends on Subversion,
|
|
|
instead pulling external code from GitHub via a Python script. If Python

IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-31493: IDLE code context -- fix code update and font update timers.
|
|
|
|
|
|
Canceling timers prevents a warning message when test_idle completes.
|
|
|
|
|
|
- bpo-31488: IDLE - Update non-key options in former extension classes. When
|
|
|
applying configdialog changes, call .reload for each feature class. Change
|
|
|
ParenMatch so updated options affect existing instances attached to
|
|
|
existing editor windows.
|
|
|
|
|
|
- bpo-31477: IDLE - Improve rstrip entry in doc. Strip trailing whitespace
|
|
|
strips more than blank spaces. Multiline string literals are not skipped.
|
|
|
|
|
|
- bpo-31480: IDLE - make tests pass with zzdummy extension disabled by
|
|
|
default.
|
|
|
|
|
|
- bpo-31421: Document how IDLE runs tkinter programs. IDLE calls tcl/tk
|
|
|
update in the background in order to make live
|
|
|
|
|
|
interaction and experimentation with tkinter applications much easier.
|
|
|
|
|
|
- bpo-31414: IDLE -- fix tk entry box tests by deleting first. Adding to an
|
|
|
int entry is not the same as deleting and inserting because int('') will
|
|
|
fail.
|
|
|
|
|
|
- bpo-31051: Rearrange IDLE configdialog GenPage into Window, Editor, and
|
|
|
Help sections.
|
|
|
|
|
|
- bpo-30617: IDLE - Add docstrings and tests for outwin subclass of editor.
|
|
|
|
|
|
Move some data and functions from the class to module level. Patch by
|
|
|
Cheryl Sabella.
|
|
|
|
|
|
- bpo-31287: IDLE - Do not modify tkinter.message in test_configdialog.
|
|
|
|
|
|
- bpo-27099: Convert IDLE's built-in 'extensions' to regular features.
|
|
|
|
|
|
About 10 IDLE features were implemented as supposedly optional extensions.
|
|
|
Their different behavior could be confusing or worse for users and not
|
|
|
good for maintenance. Hence the conversion.
|
|
|
|
|
|
The main difference for users is that user configurable key bindings for
|
|
|
builtin features are now handled uniformly. Now, editing a binding in a
|
|
|
keyset only affects its value in the keyset. All bindings are defined
|
|
|
together in the system-specific default keysets in config-extensions.def.
|
|
|
All custom keysets are saved as a whole in config-extension.cfg. All take
|
|
|
effect as soon as one clicks Apply or Ok.
|
|
|
|
|
|
The affected events are '<<force-open-completions>>', '<<expand-word>>',
|
|
|
'<<force-open-calltip>>', '<<flash-paren>>', '<<format-paragraph>>',
|
|
|
'<<run-module>>', '<<check-module>>', and '<<zoom-height>>'. Any (global)
|
|
|
customizations made before 3.6.3 will not affect their keyset-specific
|
|
|
customization after 3.6.3. and vice versa.

|
|
|
|
|

(idea from Cheryl Sabella). Move related functions to positions after the
|
|
|
create widgets function.
|
|
|
|
|
|
In test_configdialog: Fix test_font_set so not order dependent. Fix
|
|
|
renamed test_indent_scale so it tests the widget. Adjust tests for
|
|
|
movement of set_samples call. Add tests for load functions. Put all font
|
|
|
tests in one class and tab indent tests in another. Except for two lines,
|
|
|
these tests completely cover the related functions.

Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-30983: gdb integration commands (py-bt, etc.) work on optimized shared
|
|
|
builds now, too. PEP 523 introduced _PyEval_EvalFrameDefault which
|
|
|
inlines PyEval_EvalFrameEx on non-debug shared builds. This broke the
|
|
|
ability to use py-bt, py-up, and a few other Python-specific gdb
|
|
|
integrations. The problem is fixed by only looking for
|
|
|
_PyEval_EvalFrameDefault frames in python-gdb.py. Original patch by Bruno
|
|
|
"Polaco" Penteado.
|
|
|
|
|
|
- bpo-29748: Added the slice index converter in Argument Clinic.
|
|
|
|
|
|
- bpo-24037: Argument Clinic now uses the converter `bool(accept={int})`
|
|
|
rather than `int` for semantical booleans. This avoids repeating the
|
|
|
default value for Python and C and will help in converting to `bool` in
|
|
|
future.
|
|
|
|
|
|
- bpo-29367: python-gdb.py now supports also ``method-wrapper``
|
|
|
(``wrapperobject``) objects.
|
|
|
|
|
|
- bpo-28023: Fix python-gdb.py didn't support new dict implementation.
|
|
|
|
|
|
- bpo-15369: The pybench and pystone microbenchmark have been removed from
|
|
|
Tools. Please use the new Python benchmark suite
|
|
|
https://github.com/python/performance which is more reliable and includes
|
|
|
a portable version of pybench working on Python 2 and Python 3.
|
|
|
|
|
|
- bpo-28102: The zipfile module CLI now prints usage to stderr. Patch by
|
|

Stephen J. Turnbull.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-31338: Added the ``Py_UNREACHABLE()`` macro for code paths which are
|
|
|
never expected to be reached. This and a few other useful macros are now
|
|
|
documented in the C API manual.
|
|
|
|
|
|
- bpo-30832: Remove own implementation for thread-local storage.
|
|
|
|
|
|
CPython has provided the own implementation for thread-local storage (TLS)
|
|
|
on Python/thread.c, it's used in the case which a platform has not
|
|
|
supplied native TLS. However, currently all supported platforms (Windows
|
|
|
and pthreads) have provided native TLS and defined the Py_HAVE_NATIVE_TLS
|
|
|
macro with unconditional in any case.
|
|
|
|
|
|
- bpo-30708: PyUnicode_AsWideCharString() now raises a ValueError if the
|
|
|
second argument is NULL and the wchar_t\* string contains null characters.
|
|
|
|
|
|
- bpo-16500: Deprecate PyOS_AfterFork() and add PyOS_BeforeFork(),
|
|
|
PyOS_AfterFork_Parent() and PyOS_AfterFork_Child().
|
|
|
|
|
|
- bpo-6532: The type of results of PyThread_start_new_thread() and
|
|
|
PyThread_get_thread_ident(), and the id parameter of
|
|
|
PyThreadState_SetAsyncExc() changed from "long" to "unsigned long".
|
|
|
|
|
|
- bpo-27867: Function PySlice_GetIndicesEx() is deprecated and replaced with
|
|
|
a macro if Py_LIMITED_API is not set or set to the value between
|
|
|
0x03050400 and 0x03060000 (not including) or 0x03060100 or higher. Added
|
|
|
functions PySlice_Unpack() and PySlice_AdjustIndices().
|
|
|
|
|
|
- bpo-29083: Fixed the declaration of some public API functions.
|
|
|
PyArg_VaParse() and PyArg_VaParseTupleAndKeywords() were not available in
|
|
|
limited API. PyArg_ValidateKeywordArguments(), PyArg_UnpackTuple() and
|
|
|
Py_BuildValue() were not available in limited API of version < 3.3 when
|
|
|
PY_SSIZE_T_CLEAN is defined.
|
|
|
|
|
|
- bpo-28769: The result of PyUnicode_AsUTF8AndSize() and PyUnicode_AsUTF8()
|
|
|
is now of type ``const char *`` rather of ``char *``.
|
|
|
|
|
|
- bpo-29058: All stable API extensions added after Python 3.2 are now
|
|
|
available only when Py_LIMITED_API is set to the PY_VERSION_HEX value of
|
|
|
the minimum Python version supporting this API.
|
|
|
|
|
|
- bpo-28822: The index parameters *start* and *end* of PyUnicode_FindChar()
|
|
|
are now adjusted to behave like ``str[start:end]``.
|
|
|
|
|
|
- bpo-28808: PyUnicode_CompareWithASCIIString() now never raises exceptions.
|
|
|
|
|
|
- bpo-28761: The fields name and doc of structures PyMemberDef, PyGetSetDef,
|
|
|
PyStructSequence_Field, PyStructSequence_Desc, and wrapperbase are now of
|
|
|
type ``const char *`` rather of ``char *``.
|
|
|
|
|
|
- bpo-28748: Private variable _Py_PackageContext is now of type ``const char
|
|
|
*`` rather of ``char *``.
|
|
|
|
|
|
- bpo-19569: Compiler warnings are now emitted if use most of deprecated
|
|
|
functions.
|
|
|
|

|
|
|
PyUnicode_AsDecodedObject(), PyUnicode_AsDecodedUnicode() and
|

Build
|
|
|
-----
|
|
|
|
|
|
- bpo-5755: Move ``-Wstrict-prototypes`` option to ``CFLAGS_NODIST`` from
|
|
|
``OPT``. This option emitted annoying warnings when building extension
|
|
|
modules written in C++.
|
|
|
|
|
|
- bpo-33614: Ensures module definition files for the stable ABI on Windows
|

|
are correctly regenerated.
|
|
|
|
|
|
- bpo-33522: Enable CI builds on Visual Studio Team Services at

https://python.visualstudio.com/cpython
|
|

|
|
|
|
|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-33656: On Windows, add API call saying that tk scales for DPI. On
|
|
|
Windows 8.1+ or 10, with DPI compatibility properties of the Python binary
|
|
|
unchanged, and a monitor resolution greater than 96 DPI, this should make
|
|
|
text and lines sharper. It should otherwise have no effect.
|
|
|
|
|
|
- bpo-33768: Clicking on a context line moves that line to the top of the
|
|
|
editor window.
|
|
|
|
|
|
- bpo-33763: IDLE: Use read-only text widget for code context instead of
|
|
|
label widget.
|
|
|
|
|
|
- bpo-33664: Scroll IDLE editor text by lines. Previously, the mouse wheel
|
|
|
and scrollbar slider moved text by a fixed number of pixels, resulting in
|
|
|
partial lines at the top of the editor box. The change also applies to
|
|
|
the shell and grep output windows, but not to read-only text views.
|
|
|
|
|
|
- bpo-33679: Enable theme-specific color configuration for Code Context. Use
|
|
|
the Highlights tab to see the setting for built-in themes or add settings
|
|
|
to custom themes.
|
|
|
|
|
|
- bpo-33642: Display up to maxlines non-blank lines for Code Context. If
|
|
|
there is no current context, show a single blank line.
|
|
|
|
|
|
- bpo-33628: IDLE: Cleanup codecontext.py and its test.
|
|
|
|
|
|
- bpo-33564: IDLE's code context now recognizes async as a block opener.
|
|
|
|
|
|
- bpo-29706: IDLE now colors async and await as keywords in 3.6. They become
|
|
|
full keywords in 3.7.
|
|
|
|
|
|
- bpo-21474: Update word/identifier definition from ascii to unicode. In
|
|
|
text and entry boxes, this affects selection by double-click, movement
|
|
|
left/right by control-left/right, and deletion left/right by
|
|
|
control-BACKSPACE/DEL.
|
|
|
|
|
|
- bpo-33204: IDLE: consistently color invalid string prefixes. A 'u' string
|
|
|
prefix cannot be paired with either 'r' or 'f'. Consistently color as much
|
|
|
of the prefix, starting at the right, as is valid. Revise and extend
|
|
|
colorizer test.
|
|
|
|
|
|
- bpo-32831: Add docstrings and tests for codecontext.
|
|
|
|
|
|
Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-33189: :program:`pygettext.py` now recognizes only literal strings as
|
|
|
docstrings and translatable strings, and rejects bytes literals and
|
|
|
f-string expressions.
|
|
|
|
|
|
- bpo-31920: Fixed handling directories as arguments in the ``pygettext``
|
|
|
script. Based on patch by Oleg Krasnikov.
|
|
|
|
|
|
- bpo-29673: Fix pystackv and pystack gdbinit macros.
|
|
|
|
|
|
- bpo-32885: Add an ``-n`` flag for ``Tools/scripts/pathfix.py`` to disable
|
|
|
automatic backup creation (files with ``~`` suffix).
|
|
|
|
|
|
- bpo-31583: Fix 2to3 for using with --add-suffix option but without
|
|
|
--output-dir option for relative path to files in current directory.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-32374: Document that m_traverse for multi-phase initialized modules
|
|
|
can be called with m_state=NULL, and add a sanity check
|
|
|

|
|
|
|
|
- bpo-32028: Leading whitespace is now correctly ignored when generating

- bpo-32457: Improves handling of denormalized executable path when
|
|
|
launching Python.
|
|
|
|
|
|
- bpo-32370: Use the correct encoding for ipconfig output in the uuid
|
|
|
module. Patch by Segev Finer.
|
|
|
|
|
|
- bpo-29248: Fix :func:`os.readlink` on Windows, which was mistakenly
|
|
|
treating the ``PrintNameOffset`` field of the reparse data buffer as a
|
|
|
number of characters instead of bytes. Patch by Craig Holmquist and SSE4.
|
|
|
|
|
|
- bpo-32588: Create standalone _distutils_findvs module.
|
|
|
|
|
|
macOS
|
|
|
-----
|
|
|
|
|
|
- bpo-32726: Provide an additional, more modern macOS installer variant that
|
|
|
supports macOS 10.9+ systems in 64-bit mode only. Upgrade the supplied
|
|
|
third-party libraries to OpenSSL 1.0.2n, XZ 5.2.3, and SQLite 3.22.0. The
|
|
|
10.9+ installer now links with and supplies its own copy of Tcl/Tk 8.6.8.
|
|
|
|
|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-32984: Set ``__file__`` while running a startup file. Like Python,
|
|
|
IDLE optionally runs one startup file in the Shell window before
|
|
|
presenting the first interactive input prompt. For IDLE, ``-s`` runs a
|
|
|
file named in environmental variable :envvar:`IDLESTARTUP` or
|
|
|
:envvar:`PYTHONSTARTUP`; ``-r file`` runs ``file``. Python sets
|
|
|
``__file__`` to the startup file name before running the file and unsets
|
|
|
it before the first prompt. IDLE now does the same when run normally,
|
|
|
without the ``-n`` option.
|
|
|
|
|
|
- bpo-32940: Simplify and rename StringTranslatePseudoMapping in pyparse.
|
|
|
|
|
|
- bpo-32916: Change ``str`` to ``code`` in pyparse.
|
|
|
|
|
|
- bpo-32905: Remove unused code in pyparse module.
|
|
|
|
|
|
- bpo-32874: Add tests for pyparse.
|
|
|
|
|
|
- bpo-32837: Using the system and place-dependent default encoding for
|
|
|
open() is a bad idea for IDLE's system and location-independent files.
|
|
|
|
|
|
- bpo-32826: Add "encoding=utf-8" to open() in IDLE's test_help_about. GUI
|
|
|
test test_file_buttons() only looks at initial ascii-only lines, but
|
|
|
failed on systems where open() defaults to 'ascii' because readline()
|
|
|
internally reads and decodes far enough ahead to encounter a non-ascii
|
|
|
character in CREDITS.txt.
|
|
|
|
|
|
- bpo-32765: Update configdialog General tab docstring to add new widgets to
|
|
|
the widget list.
|
|
|
|
|
|
Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-24960: 2to3 and lib2to3 can now read pickled grammar files using
|
|
|
pkgutil.get_data() rather than probing the filesystem. This lets 2to3 and
|
|
|
lib2to3 work when run from a zipfile.
|
|
|
|
|
|
- bpo-32222: Fix pygettext not extracting docstrings for functions with type
|
|
|
annotated arguments. Patch by Toby Harradine.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-29084: Undocumented C API for OrderedDict has been excluded from the
|
|
|
limited C API. It was added by mistake and actually never worked in the
|
|
|
limited C API.

|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-32176: co_flags.CO_NOFREE is now always set correctly by the code
|
|
|
object constructor based on freevars and cellvars, rather than needing to
|
|
|
be set correctly by the caller. This ensures it will be cleared
|
|
|
automatically when additional cell references are injected into a modified
|
|
|
code object and function.
|
|
|
|
|
|
- bpo-31949: Fixed several issues in printing tracebacks
|
|
|
(PyTraceBack_Print()).
|
|
|
|
|
|
* Setting sys.tracebacklimit to 0 or less now suppresses printing tracebacks.
|
|
|
* Setting sys.tracebacklimit to None now causes using the default limit.
|
|
|
* Setting sys.tracebacklimit to an integer larger than LONG_MAX now means using
|
|
|
the limit LONG_MAX rather than the default limit.
|
|
|
* Fixed integer overflows in the case of more than 2**31 traceback items on
|
|
|
Windows.
|
|
|
* Fixed output errors handling.
|
|
|
|
|
|
- bpo-30696: Fix the interactive interpreter looping endlessly when no
|
|
|
memory.
|
|
|
|
|
|
- bpo-20047: Bytearray methods partition() and rpartition() now accept only
|
|
|
bytes-like objects as separator, as documented. In particular they now
|
|
|
raise TypeError rather of returning a bogus result when an integer is
|
|
|
passed as a separator.
|
|
|
|
|
|
- bpo-31852: Fix a segmentation fault caused by a combination of the async
|
|
|
soft keyword and continuation lines.
|
|
|
|
|
|
- bpo-21720: BytesWarning no longer emitted when the *fromlist* argument of
|
|
|
``__import__()`` or the ``__all__`` attribute of the module contain bytes
|
|
|
instances.

|
|
|
- bpo-31825: Fixed OverflowError in the 'unicode-escape' codec and in
|
|
|
codecs.escape_decode() when decode an escaped non-ascii byte.
|
|
|
|
|
|
- bpo-28603: Print the full context/cause chain of exceptions on interpreter
|
|
|
exit, even if an exception in the chain is unhashable or compares equal to
|
|
|
later ones. Patch by Zane Bitter.
|
|
|
|
|
|
- bpo-31786: Fix timeout rounding in the select module to round correctly
|
|
|
negative timeouts between -1.0 and 0.0. The functions now block waiting
|
|
|
for events as expected. Previously, the call was incorrectly non-blocking.
|
|
|
Patch by Pablo Galindo.
|
|
|
|
|
|
- bpo-31642: Restored blocking "from package import module" by setting
|
|
|
sys.modules["package.module"] to None.

|
- bpo-31492: Fix assertion failures in case of failing to import from a
|
|

- bpo-31926: Fixed Argument Clinic sometimes causing compilation errors when
|
|
|
there was more than one function and/or method in a .c file with the same
|
|
|
name.
|
|
|
|
|
|
- bpo-28791: Update Windows builds to use SQLite 3.21.0.
|
|

|
|
|
- bpo-28791: Update OS X installer to use SQLite 3.21.0.

|
|
|
|
|
|
- bpo-31536: Avoid wholesale rebuild after `make regen-all` if nothing
|
|
|
changed.
|
|
|
|
|
|
Windows
|
|
|
-------
|
|
|
|
|
|
- bpo-1102: Return ``None`` when ``View.Fetch()`` returns
|
|
|
``ERROR_NO_MORE_ITEMS`` instead of raising ``MSIError``.
|
|
|
|
|
|
Initial patch by Anthony Tuininga.
|
|
|
|
|
|
- bpo-31944: Fixes Modify button in Apps and Features dialog.
|
|

|
|
macOS

|
|
|
|
|
|
- bpo-31392: Update macOS installer to use OpenSSL 1.0.2m
|
|
|
|
|
|
IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-32207: Improve tk event exception tracebacks in IDLE. When tk event
|
|
|
handling is driven by IDLE's run loop, a confusing and distracting
|
|
|
queue.EMPTY traceback context is no longer added to tk event exception
|
|
|
tracebacks. The traceback is now the same as when event handling is
|
|
|
driven by user code. Patch based on a suggestion by Serhiy Storchaka.
|
|
|
|
|
|
- bpo-32164: Delete unused file idlelib/tabbedpages.py. Use of TabbedPageSet
|
|
|
in configdialog was replaced by ttk.Notebook.
|
|
|
|
|
|
- bpo-32100: IDLE: Fix old and new bugs in pathbrowser; improve tests. Patch
|
|
|
mostly by Cheryl Sabella.
|
|
|
|
|
|
- bpo-31858: IDLE -- Restrict shell prompt manipulation to the shell. Editor
|
|
|
and output windows only see an empty last prompt line. This simplifies
|
|
|
the code and fixes a minor bug when newline is inserted. Sys.ps1, if
|
|
|
present, is read on Shell start-up, but is not set or changed.
|
|
|
|
|
|
- bpo-31860: The font sample in the IDLE configuration dialog is now
|
|
|
editable. Changes persist while IDLE remains open
|
|
|
|
|
|
- bpo-31836: Test_code_module now passes if run after test_idle, which sets
|
|
|
ps1.
|
|
|
|
|
|
The code module uses sys.ps1 if present or sets it to '>>> ' if not.
|
|
|
Test_code_module now properly tests both behaviors. Ditto for ps2.
|
|
|
|
|
|
- bpo-28603: Fix a TypeError that caused a shell restart when printing a
|
|
|
traceback that includes an exception that is unhashable. Patch by Zane
|
|
|
Bitter.
|
|
|
|
|
|
- bpo-13802: Use non-Latin characters in the IDLE's Font settings sample.
|
|
|
Even if one selects a font that defines a limited subset of the unicode
|
|
|
Basic Multilingual Plane, tcl/tk will use other fonts that define a
|
|
|
character. The expanded example give users of non-Latin characters a
|
|
|
better idea of what they might see in IDLE's shell and editors. To make
|
|
|
room for the expanded sample, frames on the Font tab are re-arranged. The
|
|
|
Font/Tabs help explains a bit about the additions.
|
|
|
|
|
|
- bpo-31460: Simplify the API of IDLE's Module Browser.
|
|
|
|
|
|
Passing a widget instead of an flist with a root widget opens the option
|
|
|
of creating a browser frame that is only part of a window. Passing a full
|
|
|
file name instead of pieces assumed to come from a .py file opens the
|
|
|
possibility of browsing python files that do not end in .py.
|
|
|
|
|
|
- bpo-31649: IDLE - Make _htest, _utest parameters keyword only.
|
|
|
|
|
|
- bpo-31559: Remove test order dependence in idle_test.test_browser.
|
|
|
|
|
|
- bpo-31459: Rename IDLE's module browser from Class Browser to Module
|
|
|
Browser. The original module-level class and method browser became a
|
|
|
module browser, with the addition of module-level functions, years ago.
|
|
|
Nested classes and functions were added yesterday. For
|
|
|
back-compatibility, the virtual event <<open-class-browser>>, which
|
|
|
appears on the Keys tab of the Settings dialog, is not changed. Patch by
|
|
|
Cheryl Sabella.
|
|
|
|
|
|
- bpo-31500: Default fonts now are scaled on HiDPI displays.
|
|
|
|
|
|
- bpo-1612262: IDLE module browser now shows nested classes and functions.
|
|
|
Original patches for code and tests by Guilherme Polo and Cheryl Sabella,
|
|
|
respectively.
|
|
|
|
|
|
Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-30722: Make redemo work with Python 3.6 and newer versions.
|
|
|
|
|
|
Also, remove the ``LOCALE`` option since it doesn't work with string
|
|
|
patterns in Python 3.
|
|
|
|
|
|
Patch by Christoph Sarnowski.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-20891: Fix PyGILState_Ensure(). When PyGILState_Ensure() is called in
|
|
|
a non-Python thread before PyEval_InitThreads(), only call
|
|
|
PyEval_InitThreads() after calling PyThreadState_New() to fix a crash.
|
|
|
|
|
|
- bpo-31532: Fix memory corruption due to allocator mix in getpath.c between
|
|
|
Py_GetPath() and Py_SetPath()
|
|
|
|
|
|
- bpo-30697: The `PyExc_RecursionErrorInst` singleton is removed and
|
|
|
`PyErr_NormalizeException()` does not use it anymore. This singleton is
|
|
|
persistent and its members being never cleared may cause a segfault during
|
|
|
finalization of the interpreter. See also issue #22898.

Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-31471: Fix an assertion failure in `subprocess.Popen()` on Windows, in
|
|
|
case the env argument has a bad keys() method. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31418: Fix an assertion failure in `PyErr_WriteUnraisable()` in case
|
|
|
of an exception with a bad ``__module__`` attribute. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31416: Fix assertion failures in case of a bad warnings.filters or
|
|
|
warnings.defaultaction. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31411: Raise a TypeError instead of SystemError in case
|
|
|
warnings.onceregistry is not a dictionary. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31373: Fix several possible instances of undefined behavior due to
|
|
|
floating-point demotions.
|
|
|
|
|
|
- bpo-30465: Location information (``lineno`` and ``col_offset``) in
|
|
|
f-strings is now (mostly) correct. This fixes tools like flake8 from
|
|
|
showing warnings on the wrong line (typically the first line of the file).
|
|
|
|
|
|
- bpo-31343: Include sys/sysmacros.h for major(), minor(), and makedev().
|
|
|
GNU C libray plans to remove the functions from sys/types.h.
|
|
|
|
|
|
- bpo-31291: Fix an assertion failure in `zipimport.zipimporter.get_data` on
|
|
|
Windows, when the return value of ``pathname.replace('/','\\')`` isn't a
|
|
|
string. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-31271: Fix an assertion failure in the write() method of
|
|
|
`io.TextIOWrapper`, when the encoder doesn't return a bytes object. Patch
|
|
|
by Oren Milman.
|
|
|
|
|
|
- bpo-31243: Fix a crash in some methods of `io.TextIOWrapper`, when the
|
|
|
decoder's state is invalid. Patch by Oren Milman.
|
|
|
|
|
|
- bpo-30721: ``print`` now shows correct usage hint for using Python 2
|
|
|
redirection syntax. Patch by Sanyam Khurana.
|
|
|
|
|
|
- bpo-31070: Fix a race condition in importlib _get_module_lock().
|
|
|
|
|
|
- bpo-31095: Fix potential crash during GC caused by ``tp_dealloc`` which
|
|
|
doesn't call ``PyObject_GC_UnTrack()``.
|
|
|
|
|
|
- bpo-31071: Avoid masking original TypeError in call with * unpacking when
|
|
|
other arguments are passed.
|
|
|
|
|
|
- bpo-30978: str.format_map() now passes key lookup exceptions through.
|
|
|
Previously any exception was replaced with a KeyError exception.
|
|
|
|
|
|
- bpo-30808: Use _Py_atomic API for concurrency-sensitive signal state.
|
|
|
|
|
|
- bpo-30876: Relative import from unloaded package now reimports the package
|
|
|
instead of failing with SystemError. Relative import from non-package now
|
|
|
fails with ImportError rather than SystemError.
|
|
|
|
|
|
- bpo-30703: Improve signal delivery.
|
|
|
|
|
|
Avoid using Py_AddPendingCall from signal handler, to avoid calling
|
|
|
signal-unsafe functions. The tests I'm adding here fail without the rest
|
|
|
of the patch, on Linux and OS X. This means our signal delivery logic had
|
|
|
defects (some signals could be lost).
|
|
|
|
|
|
- bpo-30765: Avoid blocking in pthread_mutex_lock() when
|
|
|
PyThread_acquire_lock() is asked not to block.
|
|
|
|
|
|
- bpo-31161: Make sure the 'Missing parentheses' syntax error message is
|
|
|
only applied to SyntaxError, not to subclasses. Patch by Martijn Pieters.
|
|
|
|
|
|
- bpo-30814: Fixed a race condition when import a submodule from a package.
|
|
|
|
|
|
- bpo-30597: ``print`` now shows expected input in custom error message when
|
|
|
used as a Python 2 statement. Patch by Sanyam Khurana.
|
|
|
|
|
|

|
|
|
cycle: clear the variable storing the last exception on success.

|
|
|
|
|
- bpo-31457: LoggerAdapter objects can now be nested.
|
|

|
|
|
- bpo-31400: Improves SSL error handling to avoid losing error numbers.
|
|
|
|
|
|
- bpo-28958: ssl.SSLContext() now uses OpenSSL error information when a
|
|
|
context cannot be instantiated.
|
|
|
|
|
|
- bpo-27340: SSLSocket.sendall() now uses memoryview to create slices of
|
|
|
data. This fixes support for all bytes-like object. It is also more
|
|
|
efficient and avoids costly copies.
|
|
|
|
|
|
- bpo-31178: Fix string concatenation bug in rare error path in the
|
|
|
subprocess module
|
|
|
|
|

- bpo-31350: Micro-optimize :func:`asyncio._get_running_loop` to become up
|
|
|
to 10% faster.

|
|
|
partial characters for UTF-8 input (libexpat bug 115):
|
|
|
https://github.com/libexpat/libexpat/issues/115
|

|
- bpo-29136: Add TLS 1.3 cipher suites and OP_NO_TLSv1_3.
|
|
|
|
|
|
- bpo-29212: Fix concurrent.futures.thread.ThreadPoolExecutor threads to
|
|
|
have a non repr() based thread name by default when no thread_name_prefix
|
|
|
is supplied. They will now identify themselves as
|
|
|
"ThreadPoolExecutor-y_n".
|
|
|
|
|
|
- bpo-9146: Fix a segmentation fault in _hashopenssl when standard hash
|
|
|
functions such as md5 are not available in the linked OpenSSL library. As
|
|
|
in some special FIPS-140 build environments.
|
|
|
|
|
|
- bpo-27144: The ``map()`` and ``as_completed()`` iterators in
|
|
|
``concurrent.futures`` now avoid keeping a reference to yielded objects.
|
|
|
|
|
|
- bpo-10746: Fix ctypes producing wrong PEP 3118 type codes for integer
|
|
|
types.
|
|
|
|
|
|
- bpo-22536: The subprocess module now sets the filename when
|
|
|
FileNotFoundError is raised on POSIX systems due to the executable or cwd
|
|
|
not being found.
|
|
|
|
|
|
- bpo-31249: concurrent.futures: WorkItem.run() used by ThreadPoolExecutor
|
|
|
now breaks a reference cycle between an exception object and the WorkItem
|
|
|
object.
|
|
|
|
|
|
- bpo-31247: xmlrpc.server now explicitly breaks reference cycles when using
|
|
|
sys.exc_info() in code handling exceptions.
|
|
|
|
|
|
- bpo-30102: The ssl and hashlib modules now call
|
|
|
OPENSSL_add_all_algorithms_noconf() on OpenSSL < 1.1.0. The function
|
|
|
detects CPU features and enables optimizations on some CPU architectures
|
|
|
such as POWER8. Patch is based on research from Gustavo Serra Scalet.
|
|
|
|
|
|
- bpo-31185: Fixed miscellaneous errors in asyncio speedup module.
|
|
|
|
|
|
- bpo-31135: ttk: fix the destroy() method of LabeledScale and OptionMenu
|
|
|
classes. Call the parent destroy() method even if the used attribute
|
|
|
doesn't exist. The LabeledScale.destroy() method now also explicitly
|
|
|
clears label and scale attributes to help the garbage collector to destroy
|
|
|
all widgets.
|
|
|
|
|
|
- bpo-31107: Fix `copyreg._slotnames()` mangled attribute calculation for
|
|
|
classes whose name begins with an underscore. Patch by Shane Harvey.

|
|
|
Heimes.
|
|
|
|
|
|
- bpo-30119: ftplib.FTP.putline() now throws ValueError on commands that
|
|
|
contains CR or LF. Patch by Dong-hee Na.
|
|
|
|
|
|
- bpo-30595: multiprocessing.Queue.get() with a timeout now polls its reader
|
|
|
in non-blocking mode if it succeeded to acquire the lock but the acquire
|
|
|
took longer than the timeout.
|
|
|
|
|
|
- bpo-29403: Fix ``unittest.mock``'s autospec to not fail on method-bound
|
|
|
builtin functions. Patch by Aaron Gallagher.
|
|
|
|
|
|
- bpo-30961: Fix decrementing a borrowed reference in tracemalloc.
|
|
|
|
|
|
- bpo-25684: Change ``ttk.OptionMenu`` radiobuttons to be unique across
|
|
|
instances of ``OptionMenu``.
|
|
|
|
|
|
- bpo-30886: Fix multiprocessing.Queue.join_thread(): it now waits until the
|
|
|
thread completes, even if the thread was started by the same process which
|
|
|
created the queue.
|
|
|
|
|
|
- bpo-29854: Fix segfault in readline when using readline's history-size
|
|
|
option. Patch by Nir Soffer.
|
|
|
|
|
|
- bpo-30319: socket.close() now ignores ECONNRESET error.
|
|
|
|
|
|
- bpo-30828: Fix out of bounds write in
|
|
|
`asyncio.CFuture.remove_done_callback()`.
|
|
|
|
|
|
- bpo-30807: signal.setitimer() may disable the timer when passed a tiny
|
|
|
value.
|
|
|
|
|
|
Tiny values (such as 1e-6) are valid non-zero values for setitimer(),
|
|
|
which is specified as taking microsecond-resolution intervals. However, on
|
|
|
some platform, our conversion routine could convert 1e-6 into a zero
|
|
|
interval, therefore disabling the timer instead of (re-)scheduling it.
|
|
|
|
|
|
- bpo-30441: Fix bug when modifying os.environ while iterating over it
|
|
|
|
|
|
- bpo-30532: Fix email header value parser dropping folding white space in
|
|
|
certain cases.
|
|
|
|
|
|
- bpo-30879: os.listdir() and os.scandir() now emit bytes names when called
|
|
|
with bytes-like argument.
|
|
|
|
|
|
- bpo-30746: Prohibited the '=' character in environment variable names in
|
|
|
``os.putenv()`` and ``os.spawn*()``.
|
|
|
|
|
|
- bpo-29755: Fixed the lgettext() family of functions in the gettext module.
|
|
|
They now always return bytes.

|
|
version behaves like OpenSSL 1.0.2 and no longer aborts handshake.
|
|
|
|
|
|
- bpo-30822: regrtest: Exclude tzdata from regrtest --all. When running the
|
|
|
test suite using --use=all / -u all, exclude tzdata since it makes
|
|
|
test_datetime too slow (15-20 min on some buildbots) which then times out
|
|
|
on some buildbots. Fix also regrtest command line parser to allow passing

- bpo-31493: IDLE code context -- fix code update and font update timers.
|
|
|
|
|
|
Canceling timers prevents a warning message when test_idle completes.
|
|
|
|
|
|
- bpo-31488: IDLE - Update non-key options in former extension classes. When
|
|
|
applying configdialog changes, call .reload for each feature class. Change
|
|
|
ParenMatch so updated options affect existing instances attached to
|
|
|
existing editor windows.
|
|
|
|
|
|
- bpo-31477: IDLE - Improve rstrip entry in doc. Strip trailing whitespace
|

|
|
|
|
interaction and experimentation with tkinter applications much easier.

|
|
|

|
|
|
Help sections.

Cheryl Sabella.
|

|
|
|
- bpo-31287: IDLE - Do not modify tkinter.message in test_configdialog.
|
|
|
|
|
|
- bpo-27099: Convert IDLE's built-in 'extensions' to regular features.
|
|
|
|
|
|
About 10 IDLE features were implemented as supposedly optional extensions.
|
|
|
Their different behavior could be confusing or worse for users and not
|
|
|
good for maintenance. Hence the conversion.
|
|
|
|
|
|
The main difference for users is that user configurable key bindings for
|
|
|
builtin features are now handled uniformly. Now, editing a binding in a
|
|
|
keyset only affects its value in the keyset. All bindings are defined
|
|
|
together in the system-specific default keysets in config-extensions.def.
|
|
|
All custom keysets are saved as a whole in config-extension.cfg. All take
|
|
|
effect as soon as one clicks Apply or Ok.
|
|
|
|
|
|
The affected events are '<<force-open-completions>>', '<<expand-word>>',
|
|
|
'<<force-open-calltip>>', '<<flash-paren>>', '<<format-paragraph>>',
|
|
|
'<<run-module>>', '<<check-module>>', and '<<zoom-height>>'. Any (global)
|
|
|
customizations made before 3.6.3 will not affect their keyset-specific
|
|
|
customization after 3.6.3. and vice versa.

|
|
|
- bpo-30853: IDLE -- Factor a VarTrace class out of ConfigDialog.
|
|
|
|
|
|
Instance tracers manages pairs consisting of a tk variable and a callback
|
|
|
function. When tracing is turned on, setting the variable calls the
|
|
|
function. Test coverage for the new class is 100%.

|
|
|
|
- bpo-31003: IDLE: Add more tests for General tab.

- bpo-30993: IDLE - Improve configdialog font page and tests.
|
|
|

|
|
In configdialog: Document causal pathways in create_font_tab docstring.
|
|
|
Simplify some attribute names. Move set_samples calls to var_changed_font
|
|
|
(idea from Cheryl Sabella). Move related functions to positions after the
|
|
|
create widgets function.
|
|
|
|
|
|
In test_configdialog: Fix test_font_set so not order dependent. Fix
|
|
|
renamed test_indent_scale so it tests the widget. Adjust tests for
|
|
|
movement of set_samples call. Add tests for load functions. Put all font
|
|
|
tests in one class and tab indent tests in another. Except for two lines,
|
|
|
these tests completely cover the related functions.

Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-30983: gdb integration commands (py-bt, etc.) work on optimized shared
|
|
|
builds now, too. PEP 523 introduced _PyEval_EvalFrameDefault which
|
|
|
inlines PyEval_EvalFrameEx on non-debug shared builds. This broke the
|
|
|
ability to use py-bt, py-up, and a few other Python-specific gdb
|
|
|
integrations. The problem is fixed by only looking for
|
|
|
_PyEval_EvalFrameDefault frames in python-gdb.py. Original patch by Bruno
|
|
|
"Polaco" Penteado.

Security
|
|
|
--------
|

|
|
|
|
- bpo-30730: Prevent environment variables injection in subprocess on
|
|
|
Windows. Prevent passing other environment variables and command
|
|
|
arguments.
|
|

|
|
|
- bpo-30694: Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes of multiple
|
|
|
security vulnerabilities including: CVE-2017-9233 (External entity
|
|
|
infinite loop DoS), CVE-2016-9063 (Integer overflow, re-fix),
|
|
|
CVE-2016-0718 (Fix regression bugs from 2.2.0's fix to CVE-2016-0718) and
|
|
|
CVE-2012-0876 (Counter hash flooding with SipHash). Note: the
|
|
|
CVE-2016-5300 (Use os-specific entropy sources like getrandom) doesn't
|
|
|
impact Python, since Python already gets entropy from the OS to set the
|
|
|
expat secret using ``XML_SetHashSalt()``.

- bpo-30500: Fix urllib.parse.splithost() to correctly parse fragments. For
|
|
|
example, ``splithost('//127.0.0.1#@evil.com/')`` now correctly returns the

|
|
``127.0.0.1`` host, instead of treating ``@evil.com`` as the host in an

Build
|
|
|
-----
|
|
|
|
|
|
- bpo-29941: Add ``--with-assertions`` configure flag to explicitly enable C
|
|
|
``assert()`` checks. Defaults to off. ``--with-pydebug`` implies
|
|
|
``--with-assertions``.
|
|
|
|
|
|
- bpo-28787: Fix out-of-tree builds of Python when configured with
|
|
|
``--with--dtrace``.
|
|
|
|
|
|
- bpo-29243: Prevent unnecessary rebuilding of Python during ``make test``,
|
|
|
``make install`` and some other make targets when configured with
|
|
|
``--enable-optimizations``.
|
|
|
|
|
|
- bpo-23404: Don't regenerate generated files based on file modification
|
|
|
time anymore: the action is now explicit. Replace ``make touch`` with

|
Documentation
|
|
|
-------------
|
|
|
|
|
|
- bpo-30176: Add missing attribute related constants in curses
|
|
|
documentation.
|
|
|
|
|
|
- bpo-30052: the link targets for :func:`bytes` and :func:`bytearray` are
|
|
|
now their respective type definitions, rather than the corresponding
|
|
|
builtin function entries. Use :ref:`bytes <func-bytes>` and
|
|
|
:ref:`bytearray <func-bytearray>` to reference the latter.
|
|
|
|
|
|
In order to ensure this and future cross-reference updates are applied
|
|
|
automatically, the daily documentation builds now disable the default
|
|
|
output caching features in Sphinx.
|
|
|
|
|
|
- bpo-26985: Add missing info of code object in inspect documentation.
|
|
|
|
|
|
Tools/Demos
|
|
|
-----------
|
|
|
|
|
|
- bpo-29367: python-gdb.py now supports also ``method-wrapper``
|
|
|
(``wrapperobject``) objects.
|
|
|
|
|
|
Tests
|
|
|
-----
|
|
|
|
|
|
- bpo-30357: test_thread: setUp() now uses support.threading_setup() and
|
|
|
support.threading_cleanup() to wait until threads complete to avoid random
|
|
|
side effects on following tests. Initial patch written by Grzegorz
|
|
|
Grzywacz.
|
|
|
|
|
|
- bpo-30197: Enhanced functions swap_attr() and swap_item() in the
|
|
|
test.support module. They now work when delete replaced attribute or item
|
|
|
inside the with statement. The old value of the attribute or item (or
|
|
|
None if it doesn't exist) now will be assigned to the target of the "as"
|
|
|
clause, if there is one.
|
|
|
|
|
|
Windows
|
|
|
-------
|
|
|
|
|
|
- bpo-30687: Locate msbuild.exe on Windows when building rather than
|
|
|
vcvarsall.bat
|
|
|
|
|
|
- bpo-30450: The build process on Windows no longer depends on Subversion,
|
|
|
instead pulling external code from GitHub via a Python script. If Python
|
|
|
3.6 is not found on the system (via ``py -3.6``), NuGet is used to
|
|
|
download a copy of 32-bit Python.

What's New in Python 3.6.1 final?

=================================

*Release date: 2017-03-21*

|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-29723: The ``sys.path[0]`` initialization change for bpo-29139 caused
|
|
|
a regression by revealing an inconsistency in how sys.path is initialized
|
|
|
when executing ``__main__`` from a zipfile, directory, or other import
|
|
|
location. The interpreter now consistently avoids ever adding the import
|
|
|
location's parent directory to ``sys.path``, and ensures no other
|
|
|
``sys.path`` entries are inadvertently modified when inserting the import
|
|
|
location named on the command line.
|
|
|
|

with os.fsencode() and os.fsdecode() which are already using UTF-8.
|

|
|
|
|
- bpo-28991: functools.lru_cache() was susceptible to an obscure reentrancy

What's New in Python 3.6.0 beta 1?
|
|
|
==================================
|
|
|
|
|
|
*Release date: 2016-09-12*
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-23722: The __class__ cell used by zero-argument super() is now
|
|
|
initialized from type.__new__ rather than __build_class__, so class
|
|
|
methods relying on that will now work correctly when called from metaclass
|
|
|
methods during class creation. Patch by Martin Teichmann.
|
|
|
|
|
|
- bpo-25221: Fix corrupted result from PyLong_FromLong(0) when Python is
|
|
|

Patch by Jason Fried.
|
|
|
|

|
|
|
the expressions are). This is a breaking change from the 3.6 alpha
|
|
|
releases, where backslashes are allowed anywhere in an f-string. Also,
|
|
|
require that expressions inside f-strings be enclosed within literal
|
|
|
braces, and not escapes like ``f'\x7b"hi"\x7d'``.
|
|
|
|
|
|
- bpo-28046: Remove platform-specific directories from sys.path.
|
|
|

|
|
|
|
|
|

|
|
|
is interned. This leads to more compact pickle data with protocol 4.
|
|
|
|
|
|
- bpo-27213: Rework CALL_FUNCTION* opcodes to produce shorter and more
|
|
|
efficient bytecode. Patch by Demur Rumed, design by Serhiy Storchaka,
|
|
|
reviewed by Serhiy Storchaka and Victor Stinner.
|
|
|
|
|

|
|

|
|
|
- bpo-27985: Implement PEP 526 -- Syntax for Variable Annotations. Patch by
|
|
|
Ivan Levkivskyi.
|
|
|
|
|
|
- bpo-26058: Add a new private version to the builtin dict type, incremented
|
|
|
at each dictionary creation and at each dictionary change. Implementation
|
|
|
of the PEP 509.
|
|
|
|
|
|
- bpo-27364: A backslash-character pair that is not a valid escape sequence
|
|
|
now generates a DeprecationWarning. Patch by Emanuel Barry.
|
|
|
|
|
|
- bpo-27350: `dict` implementation is changed like PyPy. It is more compact
|
|
|
and preserves insertion order. (Concept developed by Raymond Hettinger and
|
|
|
patch by Inada Naoki.)
|
|
|
|
|
|
- bpo-27911: Remove unnecessary error checks in
|
|
|
``exec_builtin_or_dynamic()``.
|
|
|
|
|
|
- bpo-27078: Added BUILD_STRING opcode. Optimized f-strings evaluation.
|
|
|
|
|
|
- bpo-17884: Python now requires systems with inttypes.h and stdint.h
|
|
|
|
|
|
- bpo-27961: Require platforms to support ``long long``. Python hasn't
|
|
|
compiled without ``long long`` for years, so this is basically a
|
|
|
formality.
|
|
|
|
|
|
- bpo-27355: Removed support for Windows CE. It was never finished, and
|

|
|
|
if the method is not defined at all. (Previously, this mechanism existed

Core and Builtins
|
|
|
-----------------
|
|
|
|
|

|
|
|
- bpo-23034: The output of a special Python build with defined COUNT_ALLOCS,
|
|
|
SHOW_ALLOC_COUNT or SHOW_TRACK_COUNT macros is now off by default. It
|
|
|
can be re-enabled using the "-X showalloccount" option. It now outputs to
|
|
|
stderr instead of stdout.
|
|
|
|
|
|
- bpo-27443: __length_hint__() of bytearray iterators no longer return a
|
|
|
negative integer for a resized bytearray.
|
|
|
|
|

|
- bpo-21708: Deprecated dbm.dumb behavior that differs from common dbm
|

|
tkinter.Variable class. They replace old methods trace_variable, trace,
|
|
|
trace_vdelete and trace_vinfo that use obsolete Tcl commands and might not
|
|
|
work in future versions of Tcl. Fixed old tracing methods:
|
|
|
trace_vdelete() with wrong mode no longer break tracing, trace_vinfo() now
|
|
|
always returns a list of pairs of strings, tracing in the "u" mode now
|
|
|
works.
|
|
|
|
|
|
- bpo-26243: Only the level argument to zlib.compress() is keyword argument

|
|
|
loads() functions and JSONEncoder and JSONDecoder class constructors in
|
|
|
the json module are now keyword-only.
|
|
|
|
|
|
- bpo-27319: Methods selection_set(), selection_add(), selection_remove()
|
|
|
and selection_toggle() of ttk.TreeView now allow passing multiple items as
|
|
|
multiple arguments instead of passing them as a tuple. Deprecated
|
|
|
undocumented ability of calling the selection() method with arguments.

|
|
|
as group indices. Based on patches by Jeroen Demeyer and Xiang Zhang.
|
|
|
|
|
|
- bpo-26754: Some functions (compile() etc) accepted a filename argument
|
|
|
encoded as an iterable of integers. Now only strings and byte-like objects
|
|
|
are accepted.

|
|
|
|

|
|

|
|
|
variables contain non-ASCII characters
|
|
|
|
|
|
- bpo-27330: Fixed possible leaks in the ctypes module.
|
|
|
|
|
|
- bpo-27238: Got rid of bare excepts in the turtle module. Original patch
|
|
|
by Jelle Zijlstra.
|
|
|
|
|
|
- bpo-27122: When an exception is raised within the context being managed by
|
|
|
a contextlib.ExitStack() and one of the exit stack generators catches and
|
|
|
raises it in a chain, do not re-raise the original exception when exiting,
|
|
|
let the new chained one through. This avoids the PEP 479 bug described in
|
|
|
issue25782.

|
|
|
by Dave Sawyer.
|
|
|
|
|
|
- bpo-27286: Fixed compiling BUILD_MAP_UNPACK_WITH_CALL opcode. Calling
|
|
|
function with generalized unpacking (PEP 448) and conflicting keyword
|
|
|
names could cause undefined behavior.
|
|
|
|
|
|
- bpo-27140: Added BUILD_CONST_KEY_MAP opcode.
|
|
|
|
|
|
- bpo-27186: Add support for os.PathLike objects to open() (part of PEP

|
519).

|
|

- bpo-27066: Fixed SystemError if a custom opener (for open()) returns a
|
|
|
negative number without setting an exception.
|
|
|
|
|
|
- bpo-26983: float() now always return an instance of exact float. The
|
|
|
deprecation warning is emitted if __float__ returns an instance of a
|
|
|
strict subclass of float. In a future versions of Python this can be an
|
|
|
error.
|
|
|
|
|
|
- bpo-27097: Python interpreter is now about 7% faster due to optimized
|
|
|
instruction decoding. Based on patch by Demur Rumed.

|
- bpo-27243: Update the __aiter__ protocol: instead of returning an
|
|
|
awaitable that resolves to an asynchronous iterator, the asynchronous
|
|
|
iterator should be returned directly. Doing the former will trigger a
|
|
|
PendingDeprecationWarning.
|
|
|
|
|
|

|
|
|
consistent name for values having multiple names. Ex: signal.Signals(6)

|
- bpo-27039: Fixed bytearray.remove() for values greater than 127. Based on
|
|
|
patch by Joe Jevnik.
|
|
|
|
|
|
- bpo-23640: int.from_bytes() no longer bypasses constructors for
|
|
|
subclasses.
|
|
|
|
|
|
- bpo-27005: Optimized the float.fromhex() class method for exact float. It
|
|
|
is now 2 times faster.
|
|
|
|
|
|
- bpo-18531: Single var-keyword argument of dict subtype was passed
|
|
|
unscathed to the C-defined function. Now it is converted to exact dict.
|
|
|
|
|
|
- bpo-26811: gc.get_objects() no longer contains a broken tuple with NULL
|
|
|
pointer.
|
|
|
|
|
|
- bpo-20120: Use RawConfigParser for .pypirc parsing, removing support for
|
|
|
interpolation unintentionally added with move to Python 3. Behavior no
|
|
|
longer does any interpolation in .pypirc files, matching behavior in
|
|
|
Python 2.7 and Setuptools 19.0.
|
|
|
|
|
|
- bpo-26249: Memory functions of the :c:func:`PyMem_Malloc` domain
|
|
|
(:c:data:`PYMEM_DOMAIN_MEM`) now use the :ref:`pymalloc allocator
|
|
|
<pymalloc>` rather than system :c:func:`malloc`. Applications calling
|
|
|
:c:func:`PyMem_Malloc` without holding the GIL can now crash: use
|
|
|
``PYTHONMALLOC=debug`` environment variable to validate the usage of
|
|
|
memory allocators in your application.
|
|
|
|
|
|
- bpo-26802: Optimize function calls only using unpacking like
|
|
|
``func(*tuple)`` (no other positional argument, no keyword): avoid copying
|
|
|
the tuple. Patch written by Joe Jevnik.
|
|
|
|
|
|
- bpo-26659: Make the builtin slice type support cycle collection.
|
|
|
|
|
|
- bpo-26718: super.__init__ no longer leaks memory if called multiple times.
|
|
|
NOTE: A direct call of super.__init__ is not endorsed!
|
|
|
|
|
|
- bpo-27138: Fix the doc comment for FileFinder.find_spec().
|
|
|
|
|
|
- bpo-27147: Mention PEP 420 in the importlib docs.
|
|
|
|
|
|
- bpo-25339: PYTHONIOENCODING now has priority over locale in setting the
|
|
|
error handler for stdin and stdout.
|
|
|
|
|
|
- bpo-26494: Fixed crash on iterating exhausting iterators. Affected classes
|
|
|
are generic sequence iterators, iterators of str, bytes, bytearray, list,
|
|
|
tuple, set, frozenset, dict, OrderedDict, corresponding views and
|
|
|
os.scandir() iterator.
|
|
|
|
|
|
- bpo-26574: Optimize ``bytes.replace(b'', b'.')`` and
|
|
|
``bytearray.replace(b'', b'.')``. Patch written by Josh Snider.
|
|
|
|
|
|
- bpo-26581: If coding cookie is specified multiple times on a line in
|
|
|
Python source code file, only the first one is taken to account.
|
|
|
|
|
|
- bpo-19711: Add tests for reloading namespace packages.
|
|
|
|
|
|
- bpo-21099: Switch applicable importlib tests to use PEP 451 API.
|
|
|
|
|
|
- bpo-26563: Debug hooks on Python memory allocators now raise a fatal error
|
|
|
if functions of the :c:func:`PyMem_Malloc` family are called without
|
|
|
holding the GIL.
|
|
|
|
|
|
- bpo-26564: On error, the debug hooks on Python memory allocators now use
|
|
|
the :mod:`tracemalloc` module to get the traceback where a memory block
|
|
|
was allocated.
|
|
|
|
|
|
- bpo-26558: The debug hooks on Python memory allocator
|
|
|
:c:func:`PyObject_Malloc` now detect when functions are called without
|
|
|
holding the GIL.
|
|
|
|
|
|
- bpo-26516: Add :envvar:`PYTHONMALLOC` environment variable to set the
|
|
|
Python memory allocators and/or install debug hooks.
|
|
|
|
|
|
- bpo-26516: The :c:func:`PyMem_SetupDebugHooks` function can now also be
|
|
|
used on Python compiled in release mode.
|
|
|
|
|
|
- bpo-26516: The :envvar:`PYTHONMALLOCSTATS` environment variable can now
|
|
|
also be used on Python compiled in release mode. It now has no effect if
|
|
|
set to an empty string.
|
|
|
|
|
|
- bpo-26516: In debug mode, debug hooks are now also installed on Python
|
|
|
memory allocators when Python is configured without pymalloc.
|
|
|
|
|
|
- bpo-26464: Fix str.translate() when string is ASCII and first replacements
|
|
|
removes character, but next replacement uses a non-ASCII character or a
|
|
|
string longer than 1 character. Regression introduced in Python 3.5.0.
|
|
|
|
|
|
- bpo-22836: Ensure exception reports from PyErr_Display() and
|
|
|
PyErr_WriteUnraisable() are sensible even when formatting them produces
|
|
|
secondary errors. This affects the reports produced by
|
|
|
sys.__excepthook__() and when __del__() raises an exception.
|
|
|
|
|
|
- bpo-26302: Correct behavior to reject comma as a legal character for
|
|
|
cookie names.
|
|
|
|
|
|
- bpo-26136: Upgrade the warning when a generator raises StopIteration from
|
|
|
PendingDeprecationWarning to DeprecationWarning. Patch by Anish Shah.
|
|
|
|
|
|
- bpo-26204: The compiler now ignores all constant statements: bytes, str,
|
|
|
int, float, complex, name constants (None, False, True), Ellipsis and
|
|
|
ast.Constant; not only str and int. For example, ``1.0`` is now ignored in
|
|
|
``def f(): 1.0``.
|
|
|
|
|
|
- bpo-4806: Avoid masking the original TypeError exception when using star
|
|
|
(``*``) unpacking in function calls. Based on patch by Hagen Fürstenau
|
|
|
and Daniel Urban.
|
|
|
|
|
|
- bpo-26146: Add a new kind of AST node: ``ast.Constant``. It can be used by
|
|
|
external AST optimizers, but the compiler does not emit directly such
|
|
|
node.
|
|
|
|
|
|
- bpo-23601: Sped-up allocation of dict key objects by using Python's small
|
|
|
object allocator. (Contributed by Julian Taylor.)
|
|
|
|
|
|
- bpo-18018: Import raises ImportError instead of SystemError if a relative
|
|
|
import is attempted without a known parent package.
|
|
|
|
|
|
- bpo-25843: When compiling code, don't merge constants if they are equal
|
|
|
but have a different types. For example, ``f1, f2 = lambda: 1, lambda:
|
|
|
1.0`` is now correctly compiled to two different functions: ``f1()``
|
|
|
returns ``1`` (``int``) and ``f2()`` returns ``1.0`` (``float``), even if
|
|
|
``1`` and ``1.0`` are equal.
|
|
|
|
|
|
- bpo-26107: The format of the ``co_lnotab`` attribute of code objects
|
|
|
changes to support negative line number delta.
|
|
|
|
|
|
- bpo-26154: Add a new private _PyThreadState_UncheckedGet() function to get
|
|
|
the current Python thread state, but don't issue a fatal error if it is
|
|
|
NULL. This new function must be used instead of accessing directly the
|
|
|
_PyThreadState_Current variable. The variable is no more exposed since
|
|
|
Python 3.5.1 to hide the exact implementation of atomic C types, to avoid
|
|
|
compiler issues.
|
|
|
|
|
|
- bpo-25791: If __package__ != __spec__.parent or if neither __package__ or
|
|
|
__spec__ are defined then ImportWarning is raised.
|
|
|
|
|
|
- bpo-22995: [UPDATE] Comment out the one of the pickleability tests in
|
|
|
_PyObject_GetState() due to regressions observed in Cython-based projects.
|
|
|
|
|
|
- bpo-25961: Disallowed null characters in the type name.
|
|
|
|
|
|
- bpo-25973: Fix segfault when an invalid nonlocal statement binds a name
|
|
|
starting with two underscores.
|
|
|
|
|
|
- bpo-22995: Instances of extension types with a state that aren't
|
|
|
subclasses of list or dict and haven't implemented any pickle-related
|
|
|
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__, or
|
|
|
__getstate__), can no longer be pickled. Including memoryview.
|
|
|
|
|
|
- bpo-20440: Massive replacing unsafe attribute setting code with special
|
|
|
macro Py_SETREF.
|
|
|
|
|
|
- bpo-25766: Special method __bytes__() now works in str subclasses.
|
|
|
|
|
|
- bpo-25421: __sizeof__ methods of builtin types now use dynamic basic size.
|
|
|
This allows sys.getsize() to work correctly with their subclasses with
|
|
|
__slots__ defined.
|
|
|
|
|
|
- bpo-25709: Fixed problem with in-place string concatenation and utf-8
|
|
|
cache.
|
|
|
|
|
|
- bpo-5319: New Py_FinalizeEx() API allowing Python to set an exit status of
|
|
|
120 on failure to flush buffered streams.
|
|
|
|
|
|
- bpo-25485: telnetlib.Telnet is now a context manager.
|
|
|
|
|
|

|
|
|
__getattr__.
|
|
|
|
|
|
- bpo-24731: Fixed crash on converting objects with special methods
|
|
|
__bytes__, __trunc__, and __float__ returning instances of subclasses of
|
|
|
bytes, int, and float to subclasses of bytes, int, and float
|
|
|
correspondingly.
|
|
|
|
|
|
- bpo-25630: Fix a possible segfault during argument parsing in functions
|
|
|
that accept filesystem paths.
|
|
|
|
|
|
- bpo-23564: Fixed a partially broken sanity check in the _posixsubprocess
|
|
|
internals regarding how fds_to_pass were passed to the child. The bug had
|
|
|
no actual impact as subprocess.py already avoided it.
|
|
|
|
|
|
- bpo-25388: Fixed tokenizer crash when processing undecodable source code
|
|
|
with a null byte.
|
|
|
|
|
|
- bpo-25462: The hash of the key now is calculated only once in most
|
|
|
operations in C implementation of OrderedDict.
|
|
|
|
|
|
- bpo-22995: Default implementation of __reduce__ and __reduce_ex__ now
|
|
|
rejects builtin types with not defined __new__.
|
|
|
|
|
|
- bpo-24802: Avoid buffer overreads when int(), float(), compile(), exec()
|
|
|
and eval() are passed bytes-like objects. These objects are not
|
|
|
necessarily terminated by a null byte, but the functions assumed they
|
|
|
were.
|
|
|
|
|
|
- bpo-25555: Fix parser and AST: fill lineno and col_offset of "arg" node
|
|
|
when compiling AST from Python objects.
|
|
|
|
|
|
- bpo-24726: Fixed a crash and leaking NULL in repr() of OrderedDict that
|
|
|
was mutated by direct calls of dict methods.
|
|
|
|
|
|
- bpo-25449: Iterating OrderedDict with keys with unstable hash now raises
|
|
|
KeyError in C implementations as well as in Python implementation.
|
|
|
|
|
|
- bpo-25395: Fixed crash when highly nested OrderedDict structures were
|
|
|
garbage collected.
|
|
|
|
|
|
- bpo-25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now
|
|
|
between 2x and 3.5x faster.
|
|
|
|
|
|
- bpo-25399: Optimize bytearray % args using the new private _PyBytesWriter
|
|
|
API. Formatting is now between 2.5 and 5 times faster.
|
|
|
|
|
|
- bpo-25274: sys.setrecursionlimit() now raises a RecursionError if the new
|
|
|
recursion limit is too low depending at the current recursion depth.
|
|
|
Modify also the "lower-water mark" formula to make it monotonic. This mark
|
|
|
is used to decide when the overflowed flag of the thread state is reset.
|
|
|
|
|
|
- bpo-24402: Fix input() to prompt to the redirected stdout when
|
|
|
sys.stdout.fileno() fails.
|
|
|
|
|
|
- bpo-25349: Optimize bytes % args using the new private _PyBytesWriter API.
|
|
|
Formatting is now up to 2 times faster.
|
|
|
|
|
|
- bpo-24806: Prevent builtin types that are not allowed to be subclassed
|
|
|
from being subclassed through multiple inheritance.
|
|
|
|
|
|
- bpo-25301: The UTF-8 decoder is now up to 15 times as fast for error
|
|
|
handlers: ``ignore``, ``replace`` and ``surrogateescape``.

|
|
|
|
- bpo-24848: Fixed a number of bugs in UTF-7 decoding of misformed data.
|
|
|
|
|
|
- bpo-25267: The UTF-8 encoder is now up to 75 times as fast for error
|
|
|
handlers: ``ignore``, ``replace``, ``surrogateescape``, ``surrogatepass``.
|
|
|
Patch co-written with Serhiy Storchaka.
|
|
|
|
|
|
- bpo-25280: Import trace messages emitted in verbose (-v) mode are no
|
|
|
longer formatted twice.
|
|
|
|
|
|
- bpo-25227: Optimize ASCII and latin1 encoders with the ``surrogateescape``
|
|
|
error handler: the encoders are now up to 3 times as fast. Initial patch
|
|
|
written by Serhiy Storchaka.
|
|
|
|
|
|
- bpo-25003: On Solaris 11.3 or newer, os.urandom() now uses the getrandom()
|
|
|
function instead of the getentropy() function. The getentropy() function
|
|
|
is blocking to generate very good quality entropy, os.urandom() doesn't
|
|
|
need such high-quality entropy.
|
|
|
|
|
|
- bpo-9232: Modify Python's grammar to allow trailing commas in the argument
|
|
|
list of a function declaration. For example, "def f(\*, a = 3,): pass" is
|
|
|
now legal. Patch from Mark Dickinson.
|
|
|
|
|
|
- bpo-24965: Implement PEP 498 "Literal String Interpolation". This allows
|
|
|
you to embed expressions inside f-strings, which are converted to normal
|
|
|
strings at run time. Given x=3, then f'value={x}' == 'value=3'. Patch by
|
|
|
Eric V. Smith.
|
|
|
|
|
|
- bpo-26478: Fix semantic bugs when using binary operators with dictionary
|
|
|
views and tuples.
|
|
|
|
|
|
- bpo-26171: Fix possible integer overflow and heap corruption in
|
|
|
zipimporter.get_data().
|
|
|
|
|
|
- bpo-25660: Fix TAB key behaviour in REPL with readline.
|
|
|
|
|
|
- bpo-26288: Optimize PyLong_AsDouble.
|
|
|
|
|
|
- bpo-26289: Optimize floor and modulo division for single-digit longs.
|
|
|
Microbenchmarks show 2-2.5x improvement. Built-in 'divmod' function is
|
|
|
now also ~10% faster. (See also: bpo-26315)
|
|
|
|
|
|
- bpo-25887: Raise a RuntimeError when a coroutine object is awaited more
|
|
|
than once.
|
|
|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-27057: Fix os.set_inheritable() on Android, ioctl() is blocked by
|
|
|
SELinux and fails with EACCESS. The function now falls back to fcntl().
|
|
|
Patch written by Michał Bednarski.

|
|
|
|
|
|
- bpo-27031: Removed dummy methods in Tkinter widget classes: tk_menuBar()
|

|
and tk_bindForTraversal().
|
|
|
|
|
|
- bpo-14132: Fix urllib.request redirect handling when the target only has a
|
|
|
query string. Original fix by Ján Janech.
|
|
|
|
|
|
- bpo-17214: The "urllib.request" module now percent-encodes non-ASCII bytes
|
|
|
found in redirect target URLs. Some servers send Location header fields
|
|
|
with non-ASCII bytes, but "http.client" requires the request target to be
|
|
|
ASCII-encodable, otherwise a UnicodeEncodeError is raised. Based on patch
|
|
|
by Christian Heimes.
|
|
|
|
|
|
- bpo-27033: The default value of the decode_data parameter for
|
|
|
smtpd.SMTPChannel and smtpd.SMTPServer constructors is changed to False.
|
|
|
|
|
|
- bpo-27034: Removed deprecated class asynchat.fifo.
|
|
|
|
|
|
- bpo-26870: Added readline.set_auto_history(), which can stop entries being
|
|
|
automatically added to the history list. Based on patch by Tyler
|
|
|
Crompton.
|
|
|
|
|
|
- bpo-26039: zipfile.ZipFile.open() can now be used to write data into a ZIP
|
|
|
file, as well as for extracting data. Patch by Thomas Kluyver.
|
|
|
|
|
|
- bpo-26892: Honor debuglevel flag in urllib.request.HTTPHandler. Patch
|
|
|
contributed by Chi Hsuan Yen.
|
|
|
|
|
|
- bpo-22274: In the subprocess module, allow stderr to be redirected to
|
|
|
stdout even when stdout is not redirected. Patch by Akira Li.
|
|
|
|
|
|
- bpo-26807: mock_open 'files' no longer error on readline at end of file.
|
|
|
Patch from Yolanda Robla.

|
|
|
- bpo-25745: Fixed leaking a userptr in curses panel destructor.
|

|
|
|
in statistics.pvariance.
|
|
|
|
|
|
- bpo-26002: Use bisect in statistics.median instead of a linear search.
|
|
|
Patch by Upendra Kuma.
|
|
|
|
|
|
- bpo-25974: Make use of new Decimal.as_integer_ratio() method in statistics
|
|
|
module. Patch by Stefan Krah.
|
|

|
|
|
Patch by Georg Brandl.
|
|
|
|
|
|
- bpo-26873: xmlrpc now raises ResponseError on unsupported type tags
|
|
|
instead of silently return incorrect result.
|
|
|
|
|
|
- bpo-26915: The __contains__ methods in the collections ABCs now check for
|
|
|
identity before checking equality. This better matches the behavior of
|
|
|
the concrete classes, allows sensible handling of NaNs, and makes it
|
|
|
easier to reason about container invariants.
|
|
|
|
|
|
- bpo-26711: Fixed the comparison of plistlib.Data with other types.
|
|
|
|
|
|
- bpo-24114: Fix an uninitialized variable in `ctypes.util`.
|
|
|
|
|
|
The bug only occurs on SunOS when the ctypes implementation searches for
|
|
|
the `crle` program. Patch by Xiang Zhang. Tested on SunOS by Kees Bos.
|
|
|
|
|
|
- bpo-26864: In urllib.request, change the proxy bypass host checking
|
|
|
against no_proxy to be case-insensitive, and to not match unrelated host
|
|
|
names that happen to have a bypassed hostname as a suffix. Patch by Xiang
|
|
|
Zhang.

- bpo-25788: fileinput.hook_encoded() now supports an "errors" argument for
|
|
|
passing to open. Original patch by Joseph Hackman.
|
|
|
|
|
|
- bpo-26634: recursive_repr() now sets __qualname__ of wrapper. Patch by
|
|
|
Xiang Zhang.
|
|
|
|
|
|
- bpo-26804: urllib.request will prefer lower_case proxy environment
|
|
|
variables over UPPER_CASE or Mixed_Case ones. Patch contributed by
|
|
|
Hans-Peter Jansen.
|
|
|
|
|
|
- bpo-26837: assertSequenceEqual() now correctly outputs non-stringified
|
|
|
differing items (like bytes in the -b mode). This affects
|
|
|
assertListEqual() and assertTupleEqual().
|
|
|
|
|
|
- bpo-26041: Remove "will be removed in Python 3.7" from deprecation
|

|
|
|
2 or 4 GiB. The change affects the zlib.Decompress.decompress()
|
|
|
max_length parameter, the zlib.decompress() bufsize parameter, and the
|
|
|
zlib.Decompress.flush() length parameter.

|
|
|
could potentially signal a different process.
|
|
|
|
|
|

|
|
|
the following modules: calendar, csv, enum, fileinput, ftplib, logging,

M. Rodrigues and Joel Taddei.
|

|
|
|
|
|

|
|
|
the end if the FileInput was opened with binary mode. Patch by Ryosuke
|

|
Ito.

|
|
|
platform is Cygwin). Patch by Chris Laws.
|
|
|
|
|
|
- bpo-25304: Add asyncio.run_coroutine_threadsafe(). This lets you submit a

|
|
|
|
|

|
- bpo-24657: Prevent CGIRequestHandler from collapsing slashes in the query
|
|
|
part of the URL as if it were a path. Patch from Xiang Zhang.
|
|
|
|
|
|
- bpo-25287: Don't add crypt.METHOD_CRYPT to crypt.methods if it's not

|
|
for example.
|
|

|
|
|
datetime.datetime now round microseconds to nearest with ties going to
|
|
|
nearest even integer (ROUND_HALF_EVEN), as round(float), instead of
|
|
|
rounding towards -Infinity (ROUND_FLOOR).
|
|
|

|
|
|
|
|
|

|
|
|
|

IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-20640: Add tests for idlelib.configHelpSourceEdit. Patch by Saimadhav
|
|
|
Heblikar.
|
|
|
|
|
|
- In the 'IDLE-console differences' section of the IDLE doc, clarify how
|
|
|
running with IDLE affects sys.modules and the standard streams.
|
|
|
|
|
|
- bpo-25507: fix incorrect change in IOBinding that prevented printing.
|
|
|
Augment IOBinding htest to include all major IOBinding functions.
|
|
|
|
|
|
- bpo-25905: Revert unwanted conversion of ' to ’ RIGHT SINGLE QUOTATION
|
|
|
MARK in README.txt and open this and NEWS.txt with 'ascii'. Re-encode
|
|
|
CREDITS.txt to utf-8 and open it with 'utf-8'.
|
|
|
|
|
|
- bpo-15348: Stop the debugger engine (normally in a user process) before
|
|
|
closing the debugger window (running in the IDLE process). This prevents
|
|
|
the RuntimeErrors that were being caught and ignored.
|
|
|
|
|
|
- bpo-24455: Prevent IDLE from hanging when a) closing the shell while the
|
|
|
debugger is active (15347); b) closing the debugger with the [X] button
|
|
|
(15348); and c) activating the debugger when already active (24455). The
|
|
|
patch by Mark Roseman does this by making two changes. 1. Suspend and
|
|
|
resume the gui.interaction method with the tcl vwait mechanism intended
|
|
|
for this purpose (instead of root.mainloop & .quit). 2. In gui.run, allow
|
|
|
any existing interaction to terminate first.
|
|
|
|
|
|
- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
|
|
|
to make it clearer that the program referred to is the currently running
|
|
|
user program, not IDLE itself.
|
|
|
|
|
|
- bpo-24750: Improve the appearance of the IDLE editor window status bar.
|
|
|
Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-25313: Change the handling of new built-in text color themes to better
|
|
|
address the compatibility problem introduced by the addition of IDLE Dark.
|
|
|
Consistently use the revised idleConf.CurrentTheme everywhere in idlelib.
|
|
|
|
|
|
- bpo-24782: Extension configuration is now a tab in the IDLE Preferences
|
|
|
dialog rather than a separate dialog. The former tabs are now a sorted
|
|
|
list. Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-22726: Re-activate the config dialog help button with some content
|
|
|
about the other buttons and the new IDLE Dark theme.
|
|
|
|
|
|
- bpo-24820: IDLE now has an 'IDLE Dark' built-in text color theme. It is
|
|
|
more or less IDLE Classic inverted, with a cobalt blue background.
|
|
|
Strings, comments, keywords, ... are still green, red, orange, ... . To
|
|
|
use it with IDLEs released before November 2015, hit the 'Save as New
|
|
|
Custom Theme' button and enter a new name, such as 'Custom Dark'. The
|
|
|
custom theme will work with any IDLE release, and can be modified.
|
|
|
|
|
|
- bpo-25224: README.txt is now an idlelib index for IDLE developers and
|
|
|
curious users. The previous user content is now in the IDLE doc chapter.
|
|
|
'IDLE' now means 'Integrated Development and Learning Environment'.
|
|
|
|
|
|
- bpo-24820: Users can now set breakpoint colors in Settings -> Custom
|
|
|
Highlighting. Original patch by Mark Roseman.
|
|
|
|
|
|
- bpo-24972: Inactive selection background now matches active selection
|
|
|
background, as configured by users, on all systems. Found items are now
|
|
|
always highlighted on Windows. Initial patch by Mark Roseman.
|
|
|
|
|
|
- bpo-24570: Idle: make calltip and completion boxes appear on Macs affected
|
|
|
by a tk regression. Initial patch by Mark Roseman.
|
|
|
|
|
|
- bpo-24988: Idle ScrolledList context menus (used in debugger) now work on
|
|
|
Mac Aqua. Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-24801: Make right-click for context menu work on Mac Aqua. Patch by
|
|
|
Mark Roseman.
|
|
|
|
|
|
- bpo-25173: Associate tkinter messageboxes with a specific widget. For Mac
|
|
|
OSX, make them a 'sheet'. Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-25198: Enhance the initial html viewer now used for Idle Help.
|
|
|
Properly indent fixed-pitch text (patch by Mark Roseman). Give code
|
|
|
snippet a very Sphinx-like light blueish-gray background. Re-use initial
|
|
|
width and height set by users for shell and editor. When the Table of
|
|
|
Contents (TOC) menu is used, put the section header at the top of the
|
|
|
screen.
|
|
|
|
|
|
- bpo-25225: Condense and rewrite Idle doc section on text colors.
|
|
|
|
|
|
- bpo-21995: Explain some differences between IDLE and console Python.
|
|
|
|
|
|
- bpo-22820: Explain need for *print* when running file from Idle editor.
|
|
|
|

|
- bpo-25224: Doc: augment Idle feature list and no-subprocess section.
|
|
|
|
|
|
- bpo-25219: Update doc for Idle command line options. Some were missing and
|
|
|
notes were not correct.
|
|
|
|
|
|
- bpo-24861: Most of idlelib is private and subject to change. Use
|
|
|
idleib.idle.* to start Idle. See idlelib.__init__.__doc__.
|
|
|
|
|
|
- bpo-25199: Idle: add synchronization comments for future maintainers.
|
|
|
|
|
|
- bpo-16893: Replace help.txt with help.html for Idle doc display. The new
|
|
|
idlelib/help.html is rstripped Doc/build/html/library/idle.html. It looks
|
|
|
better than help.txt and will better document Idle as released. The
|
|
|
tkinter html viewer that works for this file was written by Rose Roseman.
|
|
|
The now unused EditorWindow.HelpDialog class and helt.txt file are
|
|
|
deprecated.
|
|
|
|
|
|
- bpo-24199: Deprecate unused idlelib.idlever with possible removal in 3.6.
|
|
|
|
|

|
|
|
|
|

|
|
|
|
|

|
|
|
avoids relying on svn.python.org, which recently changed root certificate.
|
|
|
|
|
|
- bpo-25616: Tests for OrderedDict are extracted from test_collections into
|
|
|
separate file test_ordered_dict.

|
|
|
|
|
|

|
of ignored directories.
|
|
|
|

link time optimizations at build time during a make profile-opt. Some
|
|
|
compilers and toolchains are known to not produce stable code when using
|
|

|
|
|
were concurrent.
|
|
|
|
|
|
- bpo-26465: Update OS X 10.5+ 32-bit-only installer to build and link with

Security
|
|
|
--------
|
|
|
|
|
|
- bpo-32551: The ``sys.path[0]`` initialization change for bpo-29139 caused
|
|
|
a regression by revealing an inconsistency in how sys.path is initialized
|
|
|
when executing ``__main__`` from a zipfile, directory, or other import
|
|
|
location. This is considered a potential security issue, as it may lead to
|
|
|
privileged processes unexpectedly loading code from user controlled
|
|
|
directories in situations where that was not previously the case.
|
|
|
|
|
|
The interpreter now consistently avoids ever adding the import location's
|
|
|
parent directory to ``sys.path``, and ensures no other ``sys.path``
|
|
|
entries are inadvertently modified when inserting the import location
|
|
|
named on the command line. (Originally reported as bpo-29723 against
|
|
|
Python 3.6rc1, but it was missed at the time that the then upcoming Python
|
|
|
3.5.4 release would also be affected)
|
|
|
|
|
|
- bpo-30657: Fixed possible integer overflow in PyBytes_DecodeEscape,
|
|
|
CVE-2017-1000158. Original patch by Jay Bosamiya; rebased to Python 3 by
|
|
|
Miro Hrončok.
|
|
|
|
|
|

|
|

|
|
Library
|
|
|
-------
|
|
|

|
* Fixed saving bytearrays.
|
|
|
* Identical objects will be saved only once.
|
|
|
* Equal references will be load as identical objects.
|
|
|
* Added support for saving and loading recursive data structures.
|
|
|
|
|
|

Security
|
|
|
--------
|
|
|
|
|
|
- bpo-30730: Prevent environment variables injection in subprocess on
|
|
|
Windows. Prevent passing other environment variables and command
|
|
|
arguments.
|
|
|
|
|
|
- bpo-30694: Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes of multiple
|
|
|
security vulnerabilities including: CVE-2017-9233 (External entity
|
|
|
infinite loop DoS), CVE-2016-9063 (Integer overflow, re-fix),
|
|
|
CVE-2016-0718 (Fix regression bugs from 2.2.0's fix to CVE-2016-0718) and
|
|
|
CVE-2012-0876 (Counter hash flooding with SipHash). Note: the
|
|
|
CVE-2016-5300 (Use os-specific entropy sources like getrandom) doesn't
|
|
|
impact Python, since Python already gets entropy from the OS to set the
|
|
|
expat secret using ``XML_SetHashSalt()``.
|
|
|
|
|
|
- bpo-30500: Fix urllib.parse.splithost() to correctly parse fragments. For
|
|
|
example, ``splithost('//127.0.0.1#@evil.com/')`` now correctly returns the
|
|
|
``127.0.0.1`` host, instead of treating ``@evil.com`` as the host in an
|
|
|
authentication (``login@host``).
|
|
|
|
|
|
- bpo-29591: Update expat copy from 2.1.1 to 2.2.0 to get fixes of
|
|
|
CVE-2016-0718 and CVE-2016-4472. See

|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-30876: Relative import from unloaded package now reimports the package
|
|
|
instead of failing with SystemError. Relative import from non-package now
|
|
|
fails with ImportError rather than SystemError.
|
|
|
|
|
|
- bpo-30765: Avoid blocking in pthread_mutex_lock() when
|
|
|
PyThread_acquire_lock() is asked not to block.
|
|
|
|
|
|

|
|
|
deque when pass indices of wrong type.
|
|
|
|
|
|
- bpo-28876: ``bool(range)`` works even if ``len(range)`` raises
|
|
|
:exc:`OverflowError`.
|
|
|
|
|
|
- bpo-29600: Fix wrapping coroutine return values in StopIteration.
|
|
|
|
|
|
- bpo-29537: Restore runtime compatibility with bytecode files generated by
|
|
|
CPython 3.5.0 to 3.5.2, and adjust the eval loop to avoid the problems
|
|
|
that could be caused by the malformed variant of the
|
|
|
BUILD_MAP_UNPACK_WITH_CALL opcode that they may contain. Patch by Petr
|
|
|
Viktorin, Serhiy Storchaka, and Nick Coghlan.
|
|
|
|
|
|
- bpo-28598: Support __rmod__ for subclasses of str being called before
|
|
|
str.__mod__. Patch by Martijn Pieters.

|
|
Warnings could be emitted at compile time.
|
|
|
|
|
|
- bpo-29478: If max_line_length=None is specified while using the Compat32
|
|
|
policy, it is no longer ignored. Patch by Mircea Cosbuc.
|

|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-29403: Fix ``unittest.mock``'s autospec to not fail on method-bound
|
|
|
builtin functions. Patch by Aaron Gallagher.
|
|
|
|
|
|

thread completes, even if the thread was started by the same process which
|
|
|
created the queue.
|

|
|
|
- bpo-29854: Fix segfault in readline when using readline's history-size
|
|
|
option. Patch by Nir Soffer.
|
|
|
|
|
|
- bpo-30807: signal.setitimer() may disable the timer when passed a tiny
|
|
|
value.
|
|
|
|
|
|
Tiny values (such as 1e-6) are valid non-zero values for setitimer(),
|
|
|
which is specified as taking microsecond-resolution intervals. However, on
|
|
|
some platform, our conversion routine could convert 1e-6 into a zero
|
|
|
interval, therefore disabling the timer instead of (re-)scheduling it.
|
|
|

|
|
|
They now always return bytes.
|

|
|
|
when a package is only shipped with bytecodes. Patch by Alexandru
|
|
|
Ardelean.
|
|
|
|
|
|
- bpo-23890: unittest.TestCase.assertRaises() now manually breaks a
|
|
|
reference cycle to not keep objects alive longer than expected.
|
|
|
|

|
|
|
variable-argument parameters wrapped with partialmethod. Patch by Dong-hee
|
|

|
|
|
run them), --list-cases (list test identifiers, don't run them,
|
|
|
:issue:`30523`), --matchfile (load a list of test filters from a text
|
|
|
file, :issue:`30540`), --slowest (alias to --slow).
|
|
|
|
|
|

|
|
"Tests result: xxx" summary with total duration, etc.
|
|
|
|
|
|

|
|
None if it doesn't exist) now will be assigned to the target of the "as"
|
|
|
clause, if there is one.
|
|
|
|
|
|
- bpo-29571: to match the behaviour of the ``re.LOCALE`` flag,
|
|
|
test_re.test_locale_flag now uses ``locale.getpreferredencoding(False)``
|
|
|
to determine the candidate encoding for the test regex (allowing it to
|
|
|
correctly skip the test when the default locale encoding is a multi-byte

|
|
|
subclasses.
|
|
|
|
|
|
- bpo-26811: gc.get_objects() no longer contains a broken tuple with NULL
|
|
|
pointer.
|
|
|
|
|
|
- bpo-20120: Use RawConfigParser for .pypirc parsing, removing support for
|
|
|
interpolation unintentionally added with move to Python 3. Behavior no
|
|
|
longer does any interpolation in .pypirc files, matching behavior in
|
|
|
Python 2.7 and Setuptools 19.0.
|
|
|
|
|
|
- bpo-26659: Make the builtin slice type support cycle collection.
|
|
|
|
|
|
- bpo-26718: super.__init__ no longer leaks memory if called multiple times.
|
|
|
NOTE: A direct call of super.__init__ is not endorsed!
|
|
|
|
|
|
- bpo-25339: PYTHONIOENCODING now has priority over locale in setting the
|
|
|
error handler for stdin and stdout.
|
|
|
|
|
|
- bpo-26494: Fixed crash on iterating exhausting iterators. Affected classes
|
|
|
are generic sequence iterators, iterators of str, bytes, bytearray, list,
|
|
|
tuple, set, frozenset, dict, OrderedDict, corresponding views and
|
|
|
os.scandir() iterator.
|
|
|
|
|
|
- bpo-26581: If coding cookie is specified multiple times on a line in
|
|
|
Python source code file, only the first one is taken to account.
|
|
|
|
|
|
- bpo-26464: Fix str.translate() when string is ASCII and first replacements
|
|
|
removes character, but next replacement uses a non-ASCII character or a
|
|
|
string longer than 1 character. Regression introduced in Python 3.5.0.
|
|
|
|
|
|
- bpo-22836: Ensure exception reports from PyErr_Display() and
|
|
|
PyErr_WriteUnraisable() are sensible even when formatting them produces
|
|
|
secondary errors. This affects the reports produced by
|
|
|
sys.__excepthook__() and when __del__() raises an exception.
|
|
|
|
|
|
- bpo-26302: Correct behavior to reject comma as a legal character for
|
|
|
cookie names.
|
|
|
|
|
|

|
|
|

|
|
|
and Daniel Urban.
|
|
|
|
|
|
- bpo-27138: Fix the doc comment for FileFinder.find_spec().
|
|
|
|
|
|
- bpo-26154: Add a new private _PyThreadState_UncheckedGet() function to get
|
|
|
the current Python thread state, but don't issue a fatal error if it is
|
|
|
NULL. This new function must be used instead of accessing directly the
|
|
|
_PyThreadState_Current variable. The variable is no more exposed since
|
|
|
Python 3.5.1 to hide the exact implementation of atomic C types, to avoid
|
|
|
compiler issues.
|
|
|
|
|
|
- bpo-26194: Deque.insert() gave odd results for bounded deques that had
|
|
|
reached their maximum size. Now an IndexError will be raised when
|
|
|
attempting to insert into a full deque.
|
|
|
|
|
|
- bpo-25843: When compiling code, don't merge constants if they are equal
|
|
|
but have a different types. For example, ``f1, f2 = lambda: 1, lambda:
|
|
|
1.0`` is now correctly compiled to two different functions: ``f1()``
|
|
|
returns ``1`` (``int``) and ``f2()`` returns ``1.0`` (``int``), even if
|
|
|
``1`` and ``1.0`` are equal.
|
|
|
|
|
|
- bpo-22995: [UPDATE] Comment out the one of the pickleability tests in
|
|
|
_PyObject_GetState() due to regressions observed in Cython-based projects.
|
|
|
|
|
|
- bpo-25961: Disallowed null characters in the type name.
|
|
|
|
|
|
- bpo-25973: Fix segfault when an invalid nonlocal statement binds a name
|
|
|
starting with two underscores.
|
|
|
|
|
|
- bpo-22995: Instances of extension types with a state that aren't
|
|
|
subclasses of list or dict and haven't implemented any pickle-related
|
|
|
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__, or
|
|
|
__getstate__), can no longer be pickled. Including memoryview.
|
|
|
|
|
|
- bpo-20440: Massive replacing unsafe attribute setting code with special
|
|
|
macro Py_SETREF.
|

|
|
- bpo-25766: Special method __bytes__() now works in str subclasses.
|
|
|
|
|
|
- bpo-25421: __sizeof__ methods of builtin types now use dynamic basic size.
|
|
|
This allows sys.getsize() to work correctly with their subclasses with
|
|
|
__slots__ defined.
|
|
|
|
|
|
- bpo-25709: Fixed problem with in-place string concatenation and utf-8
|
|
|
cache.
|
|
|
|
|
|
- bpo-27147: Mention PEP 420 in the importlib docs.
|
|
|
|
|
|
- bpo-24097: Fixed crash in object.__reduce__() if slot name is freed inside
|
|
|
__getattr__.
|
|
|
|
|
|
- bpo-24731: Fixed crash on converting objects with special methods
|
|
|
__bytes__, __trunc__, and __float__ returning instances of subclasses of
|
|
|
bytes, int, and float to subclasses of bytes, int, and float
|
|
|
correspondingly.
|
|
|
|
|
|
- bpo-26478: Fix semantic bugs when using binary operators with dictionary
|
|
|
views and tuples.
|
|
|
|
|
|
- bpo-26171: Fix possible integer overflow and heap corruption in
|
|
|
zipimporter.get_data().
|
|
|
|
|
|
- bpo-25660: Fix TAB key behaviour in REPL with readline.
|
|
|
|
|
|
- bpo-25887: Raise a RuntimeError when a coroutine object is awaited more
|
|
|
than once.
|
|
|
|
|
|
- bpo-27243: Update the __aiter__ protocol: instead of returning an
|
|
|
awaitable that resolves to an asynchronous iterator, the asynchronous
|
|
|
iterator should be returned directly. Doing the former will trigger a
|
|
|
PendingDeprecationWarning.
|
|
|
|
|

@overload outside stubs, Reversible, DefaultDict, Text, ContextManager,
|
|
|
Type[], NewType(), TYPE_CHECKING, and numerous bug fixes (note that some
|
|
|
of the new features are not yet implemented in mypy or other static
|
|
|
analyzers). Also classes for PEP 492 (Awaitable, AsyncIterable,
|
|

AsyncIterator) have been added (in fact they made it into 3.5.1 but were
|
|
|
never mentioned).

|
|
|
|
|

names that happen to have a bypassed hostname as a suffix. Patch by Xiang
|
|
|
Zhang.
|
|
|
|
|
|
- bpo-26634: recursive_repr() now sets __qualname__ of wrapper. Patch by
|

|
Xiang Zhang.

|
|
|
separate file test_ordered_dict.
|
|
|

|
|
- bpo-26884: Fix linking extension modules for cross builds. Patch by Xavier
|
|
|
de Gaye.
|
|
|
|
|
|
- bpo-22359: Disable the rules for running _freeze_importlib and pgen when
|
|
|
cross-compiling. The output of these programs is normally saved with the
|
|
|
source code anyway, and is still regenerated when doing a native build.
|
|
|
Patch by Xavier de Gaye.
|
|
|
|
|
|
- bpo-27229: Fix the cross-compiling pgen rule for in-tree builds. Patch by
|
|
|
Xavier de Gaye.
|
|
|
|
|
|
- bpo-21668: Link audioop, _datetime, _ctypes_test modules to libm, except
|
|
|
on Mac OS X. Patch written by Xavier de Gaye.
|
|
|
|
|
|
- bpo-25702: A --with-lto configure option has been added that will enable
|
|
|
link time optimizations at build time during a make profile-opt. Some
|
|
|
compilers and toolchains are known to not produce stable code when using
|
|
|
LTO, be sure to test things thoroughly before relying on it. It can
|
|
|
provide a few % speed up over profile-opt alone.
|
|
|

|
|
|
Previously it could fail to compile properly if the math and cmath builds
|
|
|
were concurrent.
|
|
|
|
|
|
- bpo-25348: Added ``--pgo`` and ``--pgo-job`` arguments to
|
|
|
``PCbuild\build.bat`` for building with Profile-Guided Optimization. The
|
|
|
old ``PCbuild\build_pgo.bat`` script is now deprecated, and simply calls
|
|
|
``PCbuild\build.bat --pgo %*``.
|
|
|

|
|
|
that don't include the contents of the include directory (that is, 1.0.2e
|
|
|
and later).

|
|
*Release date: 2015-11-22*
|
|
|
|
|
|
Core and Builtins
|
|
|
-----------------
|
|
|
|
|
|
- bpo-25630: Fix a possible segfault during argument parsing in functions
|
|
|
that accept filesystem paths.
|
|
|
|
|
|
- bpo-23564: Fixed a partially broken sanity check in the _posixsubprocess
|
|
|
internals regarding how fds_to_pass were passed to the child. The bug had
|
|
|
no actual impact as subprocess.py already avoided it.
|
|
|
|
|
|
- bpo-25388: Fixed tokenizer crash when processing undecodable source code
|
|
|
with a null byte.
|
|
|
|
|
|
- bpo-25462: The hash of the key now is calculated only once in most
|
|
|
operations in C implementation of OrderedDict.
|
|
|
|
|
|
- bpo-22995: Default implementation of __reduce__ and __reduce_ex__ now
|
|
|
rejects builtin types with not defined __new__.
|
|
|
|
|
|
- bpo-25555: Fix parser and AST: fill lineno and col_offset of "arg" node
|
|
|
when compiling AST from Python objects.
|
|
|
|
|
|
- bpo-24802: Avoid buffer overreads when int(), float(), compile(), exec()
|
|
|
and eval() are passed bytes-like objects. These objects are not
|
|
|
necessarily terminated by a null byte, but the functions assumed they
|
|
|
were.
|
|
|
|
|
|
- bpo-24726: Fixed a crash and leaking NULL in repr() of OrderedDict that
|
|
|
was mutated by direct calls of dict methods.
|
|
|
|
|
|
- bpo-25449: Iterating OrderedDict with keys with unstable hash now raises
|
|
|
KeyError in C implementations as well as in Python implementation.
|
|
|
|
|
|
- bpo-25395: Fixed crash when highly nested OrderedDict structures were
|
|
|
garbage collected.
|
|
|
|
|
|
- bpo-25274: sys.setrecursionlimit() now raises a RecursionError if the new
|
|
|
recursion limit is too low depending at the current recursion depth.
|
|
|
Modify also the "lower-water mark" formula to make it monotonic. This mark
|
|
|
is used to decide when the overflowed flag of the thread state is reset.
|
|
|
|
|
|
- bpo-24402: Fix input() to prompt to the redirected stdout when
|
|
|
sys.stdout.fileno() fails.
|
|
|
|
|
|
- bpo-24806: Prevent builtin types that are not allowed to be subclassed
|
|
|
from being subclassed through multiple inheritance.
|
|
|
|
|
|
- bpo-24848: Fixed a number of bugs in UTF-7 decoding of misformed data.
|
|
|
|
|
|
- bpo-25280: Import trace messages emitted in verbose (-v) mode are no
|
|
|
longer formatted twice.
|
|
|
|
|
|
- bpo-25003: On Solaris 11.3 or newer, os.urandom() now uses the getrandom()
|
|
|
function instead of the getentropy() function. The getentropy() function
|
|
|
is blocking to generate very good quality entropy, os.urandom() doesn't
|
|
|
need such high-quality entropy.
|
|
|
|
|
|
- bpo-25182: The stdprinter (used as sys.stderr before the io module is
|
|
|
imported at startup) now uses the backslashreplace error handler.
|
|
|
|
|
|
- bpo-25131: Make the line number and column offset of set/dict literals and
|
|
|
comprehensions correspond to the opening brace.
|
|
|
|
|
|
- bpo-25150: Hide the private _Py_atomic_xxx symbols from the public
|
|
|
Python.h header to fix a compilation error with OpenMP.
|
|
|
PyThreadState_GET() becomes an alias to PyThreadState_Get() to avoid ABI
|
|
|
incompatibilities.
|
|
|
|
|
|
Library
|
|
|
-------
|
|
|
|
|
|
- bpo-25626: Change three zlib functions to accept sizes that fit in
|
|
|
Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a
|
|
|
regression in 3.5 where GzipFile.read() failed to read chunks larger than
|
|
|
2 or 4 GiB. The change affects the zlib.Decompress.decompress()
|
|
|
max_length parameter, the zlib.decompress() bufsize parameter, and the
|
|
|
zlib.Decompress.flush() length parameter.
|
|
|
|
|
|
- bpo-25583: Avoid incorrect errors raised by os.makedirs(exist_ok=True)
|
|
|
when the OS gives priority to errors such as EACCES over EEXIST.
|
|
|
|
|
|
- bpo-25593: Change semantics of EventLoop.stop() in asyncio.
|
|
|
|
|
|
- bpo-6973: When we know a subprocess.Popen process has died, do not allow
|
|
|
the send_signal(), terminate(), or kill() methods to do anything as they
|
|
|
could potentially signal a different process.
|
|
|
|
|
|
- bpo-25590: In the Readline completer, only call getattr() once per
|
|
|
attribute.
|
|
|
|
|
|
- bpo-25498: Fix a crash when garbage-collecting ctypes objects created by
|
|
|
wrapping a memoryview. This was a regression made in 3.5a1. Based on
|
|
|
patch by Eryksun.
|
|
|
|
|
|
- bpo-25584: Added "escape" to the __all__ list in the glob module.
|
|
|
|
|
|
- bpo-25584: Fixed recursive glob() with patterns starting with ``**``.
|
|
|
|
|
|

|
|
|
exceptions from importing packages.
|
|
|
|
|
|
- bpo-25554: Got rid of circular references in regular expression parsing.
|
|
|
|
|
|
- bpo-25510: fileinput.FileInput.readline() now returns b'' instead of '' at
|
|
|
the end if the FileInput was opened with binary mode. Patch by Ryosuke
|
|
|
Ito.
|
|
|
|
|
|
- bpo-25503: Fixed inspect.getdoc() for inherited docstrings of properties.
|
|
|
Original patch by John Mark Vandenberg.
|
|
|
|
|
|
- bpo-25515: Always use os.urandom as a source of randomness in uuid.uuid4.
|
|
|
|
|
|
- bpo-21827: Fixed textwrap.dedent() for the case when largest common
|
|
|
whitespace is a substring of smallest leading whitespace. Based on patch
|
|
|
by Robert Li.
|
|
|
|
|
|
- bpo-25447: The lru_cache() wrapper objects now can be copied and pickled
|
|
|
(by returning the original object unchanged).
|
|
|
|
|
|
- bpo-25390: typing: Don't crash on Union[str, Pattern].
|
|
|
|

|
|
|
- bpo-25407: Remove mentions of the formatter module being removed in Python
|
|
|
3.6.
|
|
|
|
|
|
- bpo-25406: Fixed a bug in C implementation of OrderedDict.move_to_end()
|
|
|
that caused segmentation fault or hang in iterating after moving several
|
|
|
items to the start of ordered dict.
|
|
|
|
|
|
- bpo-25364: zipfile now works in threads disabled builds.
|
|
|
|
|
|
- bpo-25328: smtpd's SMTPChannel now correctly raises a ValueError if both
|
|
|
decode_data and enable_SMTPUTF8 are set to true.
|
|
|
|
|
|
- bpo-25316: distutils raises OSError instead of DistutilsPlatformError when
|
|
|
MSVC is not installed.
|
|
|
|
|
|
- bpo-25380: Fixed protocol for the STACK_GLOBAL opcode in
|
|
|
pickletools.opcodes.
|
|
|
|
|
|
- bpo-23972: Updates asyncio datagram create method allowing reuseport and
|
|
|
reuseaddr socket options to be set prior to binding the socket. Mirroring
|
|
|
the existing asyncio create_server method the reuseaddr option for
|
|
|
datagram sockets defaults to True if the O/S is 'posix' (except if the
|
|
|
platform is Cygwin). Patch by Chris Laws.
|
|
|
|
|
|
- bpo-25304: Add asyncio.run_coroutine_threadsafe(). This lets you submit a
|

|
|
|
concurrent.futures.Future. By Vincent Michel.

|
|
|
first question mark (?) rather than the last. Patch from Xiang Zhang.
|
|
|

|
|
- bpo-24657: Prevent CGIRequestHandler from collapsing slashes in the query
|
|
|
part of the URL as if it were a path. Patch from Xiang Zhang.
|
|
|
|
|
|
- bpo-24483: C implementation of functools.lru_cache() now calculates key's
|
|
|
hash only once.
|
|
|
|
|
|
- bpo-22958: Constructor and update method of weakref.WeakValueDictionary
|
|
|
now accept the self and the dict keyword arguments.
|
|
|
|
|
|
- bpo-22609: Constructor of collections.UserDict now accepts the self
|
|
|
keyword argument.
|
|
|
|
|
|
- bpo-25111: Fixed comparison of traceback.FrameSummary.
|
|
|
|
|
|
- bpo-25262: Added support for BINBYTES8 opcode in Python implementation of
|
|
|
unpickler. Highest 32 bits of 64-bit size for BINUNICODE8 and BINBYTES8
|
|
|
opcodes no longer silently ignored on 32-bit platforms in C
|
|
|
implementation.
|
|
|
|
|
|
- bpo-25034: Fix string.Formatter problem with auto-numbering and nested
|
|
|
format_specs. Patch by Anthon van der Neut.

|
|
|
more understandable and correct.
|
|
|
|
|
|
- bpo-25203: Failed readline.set_completer_delims() no longer left the
|
|
|
module in inconsistent state.
|
|
|
|
|
|
- bpo-23600: Default implementation of tzinfo.fromutc() was returning wrong
|
|
|
results in some cases.
|
|
|
|
|
|
- bpo-23329: Allow the ssl module to be built with older versions of
|
|
|
LibreSSL.
|
|
|
|
|
|
- Prevent overflow in _Unpickler_Read.
|
|
|
|
|
|
- bpo-25047: The XML encoding declaration written by Element Tree now
|
|
|
respects the letter case given by the user. This restores the ability to
|
|
|
write encoding names in uppercase like "UTF-8", which worked in Python 2.
|
|
|
|
|
|
- bpo-25135: Make deque_clear() safer by emptying the deque before clearing.
|
|
|
This helps avoid possible reentrancy issues.
|
|
|
|
|
|
- bpo-19143: platform module now reads Windows version from kernel32.dll to

|
|
|
EINVAL.
|
|
|
|
|
|
- bpo-23517: Fix rounding in fromtimestamp() and utcfromtimestamp() methods
|
|
|
of datetime.datetime: microseconds are now rounded to nearest with ties
|
|
|
going to nearest even integer (ROUND_HALF_EVEN), instead of being rounding
|
|
|
towards minus infinity (ROUND_FLOOR). It's important that these methods
|
|
|
use the same rounding mode than datetime.timedelta to keep the property:
|
|
|
(datetime(1970,1,1) + timedelta(seconds=t)) ==
|
|
|
datetime.utcfromtimestamp(t). It also the rounding mode used by
|
|
|
round(float) for example.
|
|
|
|
|
|
- bpo-25155: Fix datetime.datetime.now() and datetime.datetime.utcnow() on

|
|
|
Python 3.5.0.
|
|
|
|
|
|
- bpo-25108: Omitted internal frames in traceback functions print_stack(),

|
format_stack(), and extract_stack() called without arguments.
|
|
|
|
|
|
- bpo-25118: Fix a regression of Python 3.5.0 in os.waitpid() on Windows.
|
|
|
|
|
|
- bpo-24684: socket.socket.getaddrinfo() now calls
|
|
|
PyUnicode_AsEncodedString() instead of calling the encode() method of the
|
|
|
host, to handle correctly custom string with an encode() method which
|
|
|
doesn't return a byte string. The encoder of the IDNA codec is now called
|
|
|
directly instead of calling the encode() method of the string.
|
|
|
|
|
|
- bpo-25060: Correctly compute stack usage of the BUILD_MAP opcode.
|
|
|
|
|
|
- bpo-24857: Comparing call_args to a long sequence now correctly returns a
|
|
|
boolean result instead of raising an exception. Patch by A Kaptur.
|
|
|
|
|
|
- bpo-23144: Make sure that HTMLParser.feed() returns all the data, even
|
|
|
when convert_charrefs is True.
|
|
|
|
|
|
- bpo-24982: shutil.make_archive() with the "zip" format now adds entries
|
|
|
for directories (including empty directories) in ZIP file.

|
|
|
Based on patch by John Leitch.
|
|
|
|
|
|
- bpo-16180: Exit pdb if file has syntax error, instead of trapping user in
|
|
|
an infinite loop. Patch by Xavier de Gaye.
|
|
|
|
|
|
- bpo-24891: Fix a race condition at Python startup if the file descriptor
|
|
|
of stdin (0), stdout (1) or stderr (2) is closed while Python is creating
|
|
|
sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set
|
|
|
to None if the creation of the object failed, instead of raising an
|
|
|
OSError exception. Initial patch written by Marco Paolini.
|
|
|
|
|
|
- bpo-24992: Fix error handling and a race condition (related to garbage
|
|
|
collection) in collections.OrderedDict constructor.
|
|
|
|
|
|
- bpo-24881: Fixed setting binary mode in Python implementation of FileIO on
|
|
|
Windows and Cygwin. Patch from Akira Li.

|
|
|
ssl.SSLContext.

|
|
|

IDLE
|
|
|
----
|
|
|
|
|
|
- bpo-15348: Stop the debugger engine (normally in a user process) before
|
|
|
closing the debugger window (running in the IDLE process). This prevents
|
|
|
the RuntimeErrors that were being caught and ignored.
|
|
|
|
|
|
- bpo-24455: Prevent IDLE from hanging when a) closing the shell while the
|
|
|
debugger is active (15347); b) closing the debugger with the [X] button
|
|
|
(15348); and c) activating the debugger when already active (24455). The
|
|
|
patch by Mark Roseman does this by making two changes. 1. Suspend and
|
|
|
resume the gui.interaction method with the tcl vwait mechanism intended
|
|
|
for this purpose (instead of root.mainloop & .quit). 2. In gui.run, allow
|
|
|
any existing interaction to terminate first.
|
|
|
|
|
|
- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
|
|
|
to make it clearer that the program referred to is the currently running
|
|
|
user program, not IDLE itself.
|
|
|
|
|
|
- bpo-24750: Improve the appearance of the IDLE editor window status bar.
|
|
|
Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-25313: Change the handling of new built-in text color themes to better
|
|
|
address the compatibility problem introduced by the addition of IDLE Dark.
|
|
|
Consistently use the revised idleConf.CurrentTheme everywhere in idlelib.
|
|
|
|
|
|
- bpo-24782: Extension configuration is now a tab in the IDLE Preferences
|
|
|
dialog rather than a separate dialog. The former tabs are now a sorted
|
|
|
list. Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-22726: Re-activate the config dialog help button with some content
|
|
|
about the other buttons and the new IDLE Dark theme.
|
|
|
|
|
|
- bpo-24820: IDLE now has an 'IDLE Dark' built-in text color theme. It is
|
|
|
more or less IDLE Classic inverted, with a cobalt blue background.
|
|
|
Strings, comments, keywords, ... are still green, red, orange, ... . To
|
|
|
use it with IDLEs released before November 2015, hit the 'Save as New
|
|
|
Custom Theme' button and enter a new name, such as 'Custom Dark'. The
|
|
|
custom theme will work with any IDLE release, and can be modified.
|
|
|
|
|
|
- bpo-25224: README.txt is now an idlelib index for IDLE developers and
|
|
|
curious users. The previous user content is now in the IDLE doc chapter.
|
|
|
'IDLE' now means 'Integrated Development and Learning Environment'.
|
|
|
|
|
|
- bpo-24820: Users can now set breakpoint colors in Settings -> Custom
|
|
|
Highlighting. Original patch by Mark Roseman.
|
|
|
|
|
|
- bpo-24972: Inactive selection background now matches active selection
|
|
|
background, as configured by users, on all systems. Found items are now
|
|
|
always highlighted on Windows. Initial patch by Mark Roseman.
|
|
|
|
|
|
- bpo-24570: Idle: make calltip and completion boxes appear on Macs affected
|
|
|
by a tk regression. Initial patch by Mark Roseman.
|
|
|
|
|
|

|
|
|
Mac Aqua. Patch by Mark Roseman.

|
|
|
Mark Roseman.

|
|
|
OSX, make them a 'sheet'. Patch by Mark Roseman.
|
|
|
|
|
|
- bpo-25198: Enhance the initial html viewer now used for Idle Help.
|
|
|
Properly indent fixed-pitch text (patch by Mark Roseman). Give code
|
|
|
snippet a very Sphinx-like light blueish-gray background. Re-use initial
|
|
|
width and height set by users for shell and editor. When the Table of
|
|
|
Contents (TOC) menu is used, put the section header at the top of the
|
|
|
screen.
|
|
|
|
|
|
- bpo-25225: Condense and rewrite Idle doc section on text colors.
|
|
|
|
|
|
- bpo-21995: Explain some differences between IDLE and console Python.
|
|
|
|
|
|
- bpo-22820: Explain need for *print* when running file from Idle editor.

|
- bpo-25224: Doc: augment Idle feature list and no-subprocess section.
|
|
|
|
|
|
- bpo-25219: Update doc for Idle command line options. Some were missing and
|
|
|
notes were not correct.
|
|
|
|
|
|
- bpo-24861: Most of idlelib is private and subject to change. Use
|
|
|
idleib.idle.* to start Idle. See idlelib.__init__.__doc__.
|
|
|
|
|
|
- bpo-25199: Idle: add synchronization comments for future maintainers.
|
|
|
|
|
|
- bpo-16893: Replace help.txt with help.html for Idle doc display. The new
|
|
|
idlelib/help.html is rstripped Doc/build/html/library/idle.html. It looks
|
|
|
better than help.txt and will better document Idle as released. The
|
|
|
tkinter html viewer that works for this file was written by Mark Roseman.
|
|
|
The now unused EditorWindow.HelpDialog class and helt.txt file are
|
|
|
deprecated.
|
|
|
|
|
|
- bpo-24199: Deprecate unused idlelib.idlever with possible removal in 3.6.

|
|
|
|
|
|
- bpo-12067: Rewrite Comparisons section in the Expressions chapter of the

|
|
|
|
|
|
- bpo-22980: Under Linux, GNU/KFreeBSD and the Hurd, C extensions now
|
|
|
include the architecture triplet in the extension name, to make it easy to
|
|
|
test builds for different ABIs in the same working tree. Under OS X, the
|
|
|
extension name now includes PEP 3149-style information.
|
|
|
|
|
|
- bpo-22631: Added Linux-specific socket constant CAN_RAW_FD_FRAMES. Patch
|
|
|
courtesy of Joe Jevnik.

|
- bpo-23309: Avoid a deadlock at shutdown if a daemon thread is aborted
|
|
|
while it is holding a lock to a buffered I/O object, and the main thread

|
|
|
error is emitted instead.

|
|
|
|
|
|
- bpo-23853: :meth:`socket.socket.sendall` does no more reset the socket
|
|
|
timeout each time data is sent successfully. The socket timeout is now the
|
|
|
maximum total duration to send all data.
|
|
|
|
|
|

|
|
|
result of sendto() instead of the C int type.
|
|
|
|
|
|
- bpo-23618: :meth:`socket.socket.connect` now waits until the connection
|
|
|
completes instead of raising :exc:`InterruptedError` if the connection is
|
|
|
interrupted by signals, signal handlers don't raise an exception and the
|
|
|
socket is blocking or has a timeout. :meth:`socket.socket.connect` still

no longer applied to modules already mapped with full name mapping.
|
|
|
|
|
|
- bpo-23485: select.select() is now retried automatically with the
|
|
|
recomputed timeout when interrupted by a signal, except if the signal

|
|

|
|
|
|

|
|
|
|
|
|

|
keyword-only arguments.
|
|
|
|
|
|
- bpo-23491: Added a zipapp module to support creating executable zip file
|
|
|
archives of Python code. Registered ".pyz" and ".pyzw" extensions on
|
|
|
Windows for these archives (PEP 441).

|
|
|
|
|

|
|
|
pathlib.Path objects as arguments.
|
|
|
|
|
|
- bpo-23688: Added support of arbitrary bytes-like objects and avoided
|
|

from some web servers.
|
|
|
|
|
|
- bpo-22351: The nntplib.NNTP constructor no longer leaves the connection
|
|
|
and socket open until the garbage collector cleans them up. Patch by
|
|
|
Martin Panter.
|
|
|
|
|
|
- bpo-23704: collections.deque() objects now support methods for index(),
|
|
|
insert(), and copy(). This allows deques to be registered as a
|
|
|
MutableSequence and it improves their substitutability for lists.
|
|
|
|
|
|
- bpo-23715: :func:`signal.sigwaitinfo` and :func:`signal.sigtimedwait` are
|
|
|
now retried when interrupted by a signal not in the *sigset* parameter, if
|
|
|
the signal handler does not raise an exception. signal.sigtimedwait()
|
|
|
recomputes the timeout with a monotonic clock when it is retried.
|
|
|
|
|
|
- bpo-23001: Few functions in modules mmap, ossaudiodev, socket, ssl, and
|
|
|
codecs, that accepted only read-only bytes-like object now accept writable
|
|
|
bytes-like object too.
|
|
|
|
|
|
- bpo-23646: If time.sleep() is interrupted by a signal, the sleep is now
|
|
|
retried with the recomputed delay, except if the signal handler raises an
|
|
|
exception (PEP 475).
|
|
|
|
|
|
- bpo-23136: _strptime now uniformly handles all days in week 0, including
|
|
|
Dec 30 of previous year. Based on patch by Jim Carroll.
|
|
|
|
|
|
- bpo-23700: Iterator of NamedTemporaryFile now keeps a reference to
|
|
|
NamedTemporaryFile instance. Patch by Bohuslav Kabrda.
|
|
|
|
|
|
- bpo-22903: The fake test case created by unittest.loader when it fails
|
|
|
importing a test module is now picklable.
|
|
|
|
|
|
- bpo-22181: On Linux, os.urandom() now uses the new getrandom() syscall if
|
|
|
available, syscall introduced in the Linux kernel 3.17. It is more
|
|
|
reliable and more secure, because it avoids the need of a file descriptor
|
|
|
and waits until the kernel has enough entropy.
|
|
|
|
|
|
- bpo-2211: Updated the implementation of the http.cookies.Morsel class.
|
|
|
Setting attributes key, value and coded_value directly now is deprecated.
|
|
|
update() and setdefault() now transform and check keys. Comparing for
|
|
|
equality now takes into account attributes key, value and coded_value.
|
|
|
copy() now returns a Morsel, not a dict. repr() now contains all
|
|
|
attributes. Optimized checking keys and quoting values. Added new tests.
|
|
|
Original patch by Demian Brecht.
|
|
|
|
|
|
- bpo-18983: Allow selection of output units in timeit. Patch by Julian
|
|
|
Gindi.
|
|
|
|
|
|
- bpo-23631: Fix traceback.format_list when a traceback has been mutated.
|
|
|
|
|
|
- bpo-23568: Add rdivmod support to MagicMock() objects. Patch by Håkan
|
|
|
Lövdahl.
|
|
|
|
|
|
- bpo-2052: Add charset parameter to HtmlDiff.make_file().
|
|
|
|
|
|
- bpo-23668: Support os.truncate and os.ftruncate on Windows.
|
|
|
|
|
|
- bpo-23138: Fixed parsing cookies with absent keys or values in cookiejar.
|
|
|
Patch by Demian Brecht.
|
|
|
|
|
|
- bpo-23051: multiprocessing.Pool methods imap() and imap_unordered() now
|
|
|
handle exceptions raised by an iterator. Patch by Alon Diamant and Davin
|
|
|
Potts.
|
|
|
|
|
|
- bpo-23581: Add matmul support to MagicMock. Patch by Håkan Lövdahl.
|
|
|
|
|
|
- bpo-23566: enable(), register(), dump_traceback() and
|
|
|
dump_traceback_later() functions of faulthandler now accept file
|
|
|
descriptors. Patch by Wei Wu.
|
|
|
|
|
|
- bpo-22928: Disabled HTTP header injections in http.client. Original patch
|
|
|
by Demian Brecht.
|
|
|
|
|
|
- bpo-23615: Modules bz2, tarfile and tokenize now can be reloaded with
|
|
|
imp.reload(). Patch by Thomas Kluyver.
|
|
|
|
|
|
- bpo-23605: os.walk() now calls os.scandir() instead of os.listdir(). The
|
|
|
usage of os.scandir() reduces the number of calls to os.stat(). Initial
|
|
|
patch written by Ben Hoyt.
|
|
|
|
|
|

|
|
|
platform exposes the function ``ioctl(FIOCLEX)``, but calling it fails
|
|
|
with errno is ENOTTY: "Inappropriate ioctl for device". set_inheritable()
|
|
|
now falls back to the slower ``fcntl()`` (``F_GETFD`` and then
|
|
|
``F_SETFD``).
|
|
|
|
|
|
- bpo-21389: Displaying the __qualname__ of the underlying function in the
|
|
|
repr of a bound method.
|
|
|
|
|
|
- bpo-22206: Using pthread, PyThread_create_key() now sets errno to ENOMEM

|
|

when frame.clear() has been called.
|
|
|
|
|
|
- bpo-21205: Add a new ``__qualname__`` attribute to generator, the
|
|
|
qualified name, and use it in the representation of a generator
|
|
|
(``repr(gen)``). The default name of the generator (``__name__``
|
|
|
attribute) is now get from the function instead of the code. Use
|
|
|
``gen.gi_code.co_name`` to get the name of the code.
|
|
|
|
|
|
- bpo-21669: With the aid of heuristics in SyntaxError.__init__, the parser
|
|
|
now attempts to generate more meaningful (or at least more search engine
|
|
|
friendly) error messages when "exec" and "print" are used as statements.
|
|
|
|
|
|
- bpo-21642: In the conditional if-else expression, allow an integer written
|
|
|
with no space between itself and the ``else`` keyword (e.g. ``True if
|
|
|
42else False``) to be valid syntax.
|
|
|
|
|
|
- bpo-21523: Fix over-pessimistic computation of the stack effect of some
|
|
|
opcodes in the compiler. This also fixes a quadratic compilation time
|
|
|
issue noticeable when compiling code with a large number of "and" and "or"
|
|
|

- bpo-19977: When the ``LC_TYPE`` locale is the POSIX locale (``C`` locale),
|
|
|
:py:data:`sys.stdin` and :py:data:`sys.stdout` are now using the

|
to not waste memory if these modules are not used.
|

|
|
|
ipaddress.

|
the environment variable DISTUTILS_DEBUG is set.
|
|
|
|
|
|
- bpo-4931: distutils should not produce unhelpful "error: None" messages

positional-or-keyword arguments passed as keyword arguments become
|
|
|
keyword-only.
|
|
|
|
|
|
- bpo-20334: inspect.Signature and inspect.Parameter are now hashable.
|
|
|
Thanks to Antony Lee for bug reports and suggestions.

|
instead of raising ValueError if it finds no tests
|
|
|
|
|
|
- bpo-21209: Fix asyncio.tasks.CoroWrapper to workaround a bug in yield-from

|
|
|
|
|
|
- bpo-16233: A module browser (File : Class Browser, Alt+C) requires an
|
|
|
editor window with a filename. When Class Browser is requested otherwise,
|
|
|
from a shell, output window, or 'Untitled' editor, Idle no longer displays
|
|
|
an error box. It now pops up an Open Module box (Alt+M). If a valid name
|
|
|
is entered and a module is opened, a corresponding browser is also opened.
|
|
|
|
|
|
- bpo-4832: Save As to type Python files automatically adds .py to the name
|
|
|
you enter (even if your system does not display it). Some systems
|
|
|
automatically add .txt when type is Text files.
|
|
|
|
|
|
- bpo-21986: Code objects are not normally pickled by the pickle module. To

|
|
|
Saimadhav Heblikar
|
|
|
|
|
|
- bpo-18104: Add idlelib/idle_test/htest.py with a few sample tests to begin
|
|
|
consolidating and improving human-validated tests of Idle. Change other
|
|
|
files as needed to work with htest. Running the module as __main__ runs
|
|
|
all tests.
|
|
|
|
|
|
- bpo-21139: Change default paragraph width to 72, the PEP 8 recommendation.

Build
|
|
|
-----
|
|
|
|
|
|
- bpo-15506: Use standard PKG_PROG_PKG_CONFIG autoconf macro in the
|
|
|
configure script.
|
|
|
|
|
|
- bpo-22935: Allow the ssl module to be compiled if openssl doesn't support
|
|
|
SSL 3.
|
|
|
|
|
|
- bpo-22592: Drop support of the Borland C compiler to build Python. The
|
|
|
distutils module still supports it to build extensions.
|
|
|
|
|
|
- bpo-22591: Drop support of MS-DOS, especially of the DJGPP compiler
|
|
|
(MS-DOS port of GCC).
|
|
|
|
|
|
- bpo-16537: Check whether self.extensions is empty in setup.py. Patch by
|
|
|
Jonathan Hosmer.
|
|
|
|
|
|
- bpo-22359: Remove incorrect uses of recursive make. Patch by Jonas
|
|
|
Wagner.
|
|
|
|
|
|
- bpo-21958: Define HAVE_ROUND when building with Visual Studio 2013 and
|
|
|
above. Patch by Zachary Turner.
|
|
|
|
|
|
- bpo-18093: the programs that embed the CPython runtime are now in a
|
|
|
separate "Programs" directory, rather than being kept in the Modules
|
|
|
directory.
|
|
|
|
|
|
- bpo-15759: "make suspicious", "make linkcheck" and "make doctest" in Doc/
|
|
|
now display special message when and only when there are failures.
|
|
|
|
|
|
- bpo-21141: The Windows build process no longer attempts to find Perl,
|
|
|
instead relying on OpenSSL source being configured and ready to build.
|
|
|
The ``PCbuild\build_ssl.py`` script has been re-written and re-named to
|
|
|
``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
|
|
|
for both 32 and 64 bit platforms. OpenSSL sources obtained from
|
|
|
svn.python.org will always be pre-configured and ready to build.
|
|
|
|
|
|
- bpo-21037: Add a build option to enable AddressSanitizer support.
|
|
|
|
|
|
- bpo-19962: The Windows build process now creates "python.bat" in the root
|
|
|
of the source tree, which passes all arguments through to the most
|
|
|
recently built interpreter.
|
|
|
|
|
|
- bpo-21285: Refactor and fix curses configure check to always search in a
|
|
|
ncursesw directory.
|
|
|
|
|
|
- bpo-15234: For BerkelyDB and Sqlite, only add the found library and
|
|
|
include directories if they aren't already being searched. This avoids an
|
|
|
explicit runtime library dependency.
|
|
|
|
|
|
- bpo-17861: Tools/scripts/generate_opcode_h.py automatically regenerates
|
|
|
Include/opcode.h from Lib/opcode.py if the latter gets any change.
|
|
|
|
|
|
- bpo-20644: OS X installer build support for documentation build changes in
|
|
|
3.4.1: assume externally supplied sphinx-build is available in /usr/bin.
|
|
|
|
|
|
- bpo-20022: Eliminate use of deprecated bundlebuilder in OS X builds.
|
|
|

|
|
|

|
|
|
|

|
|
|
--generate-posix-vars in pybuilddir.txt build target.

|
|
|
|
|
|

|
|
|
|
|
|
- bpo-22919: Windows build updated to support VC 14.0 (Visual Studio 2015),
|
|
|
which will be used for the official release.
|
|
|
|
|
|
- bpo-21236: Build _msi.pyd with cabinet.lib instead of fci.lib
|
|
|
|
|
|
- bpo-17128: Use private version of OpenSSL for OS X 10.5+ installer.
|
|
|
|
|
|
C API
|
|
|
-----
|
|
|
|
|
|
- bpo-14203: Remove obsolete support for view==NULL in PyBuffer_FillInfo(),
|
|
|
bytearray_getbuffer(), bytesiobuf_getbuffer() and array_buffer_getbuf().
|
|
|
All functions now raise BufferError in that case.
|
|
|
|
|
|
- bpo-22445: PyBuffer_IsContiguous() now implements precise contiguity
|
|
|
tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
|
|
|
flag. Previously the function reported false negatives for corner cases.
|
|
|
|
|
|
- bpo-22079: PyType_Ready() now checks that statically allocated type has no
|
|
|
dynamically allocated bases.
|
|
|
|
|
|

|
|
|
|
|
|
- bpo-18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`,
|
|
|
rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document
|
|
|
these functions.
|
|
|
|
|
|
- bpo-21233: Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
|
|
|
PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) is now using
|
|
|
``calloc()`` instead of ``malloc()`` for large objects which is faster and
|
|
|
use less memory.
|
|
|
|
|
|
- bpo-20942: PyImport_ImportFrozenModuleObject() no longer sets __file__ to
|
|
|
match what importlib does; this affects _frozen_importlib as well as any
|
|
|
module loaded using imp.init_frozen().
|
|
|
|
|
|
Documentation
|
|
|
-------------
|
|
|
|
|

|
|
|
clarifications. Patch by Martin Panter.
|
|
|
|
|
|
- bpo-22394: Doc/Makefile now supports ``make venv PYTHON=../python`` to
|
|

|
|
|
PYTHON=venv/bin/python3``.
|
|
|
|
|
|
- bpo-21514: The documentation of the json module now refers to new JSON RFC
|
|
|
7159 instead of obsoleted RFC 4627.
|
|
|
|
|
|
- bpo-21777: The binary sequence methods on bytes and bytearray are now
|
|
|
documented explicitly, rather than assuming users will be able to derive
|
|
|
the expected behaviour from the behaviour of the corresponding str
|
|
|
methods.
|
|
|
|
|
|
- bpo-6916: undocument deprecated asynchat.fifo class.
|
|
|
|
|
|
- bpo-17386: Expanded functionality of the ``Doc/make.bat`` script to make
|

|
- bpo-19407: New package installation and distribution guides based on the
|
|
|
Python Packaging Authority tools. Existing guides have been retained as
|
|
|
legacy links from the distutils docs, as they still contain some required
|
|
|
reference material for tool developers that isn't recorded anywhere else.
|
|
|
|
|
|
- bpo-19697: Document cases where __main__.__spec__ is None.

|
|
|
|
|
|
- bpo-22104: regrtest.py no longer holds a reference to the suite of tests

|
|
|
separate test files for each tested script.

|
|
|
Denver Coneybeare and Radu Voicilas.
|
|
|
|
|
|
- bpo-20155: Changed HTTP method names in failing tests in test_httpservers
|
|
|
so that packet filtering software (specifically Windows Base Filtering
|
|

|
|
tests.
|
|
|
|
|
|
- bpo-19493: Refactored the ctypes test package to skip tests explicitly
|
|
|
