| What's New in Python 3.6.0 beta 1? |
| ================================== |
| |
| *Release date: 2016-09-12* |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #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. |
| |
| - Issue #25221: Fix corrupted result from PyLong_FromLong(0) when Python |
| is compiled with NSMALLPOSINTS = 0. |

| by Chris Angelico. |
| |
| - Issue #27199: In tarfile, expose copyfileobj bufsize to improve throughput. |
| Patch by Jason Fried. |
| |
| - Issue #27948: In f-strings, only allow backslashes inside the braces |
| (where 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'. |
| |
| - Issue #28046: Remove platform-specific directories from sys.path. |
| |
| - Issue #28071: Add early-out for differencing from an empty set. |

| (patch by Eryk Sun) |
| |
| - Issue #25856: The __module__ attribute of extension classes and functions |
| now is interned. This leads to more compact pickle data with protocol 4. |
| |
| - Issue #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. |
| |
| - Issue #26331: Implement tokenizing support for PEP 515. Patch by Georg Brandl. |
| |

| Patch by Ivan Levkivskyi. |
| |
| - Issue #28003: Implement PEP 525 -- Asynchronous Generators. |
| |

| at each dictionary creation and at each dictionary change. Implementation of |
| the PEP 509. |
| |
| - Issue #27364: A backslash-character pair that is not a valid escape sequence |
| now generates a DeprecationWarning. Patch by Emanuel Barry. |
| |

| |
| - Issue #27961: Require platforms to support ``long long``. Python hasn't |
| compiled without ``long long`` for years, so this is basically a formality. |
| |
| - Issue #27355: Removed support for Windows CE. It was never finished, |
| and Windows CE is no longer a relevant platform for Python. |
| |
| - Implement PEP 523. |
| |
| - Issue #27870: A left shift of zero by a large integer no longer attempts |
| to allocate large amounts of memory. |
| |
| - Issue #25402: In int-to-decimal-string conversion, improve the estimate |
| of the intermediate memory required, and remove an unnecessarily strict |
| overflow check. Patch by Serhiy Storchaka. |
| |
| - Issue #27214: In long_invert, be more careful about modifying object |
| returned by long_add, and remove an unnecessary check for small longs. |

| unreliable ldexp implementations. |
| |
| - Issue #24254: Make class definition namespace ordered by default. |
| |
| - Issue #27662: Fix an overflow check in ``List_New``: the original code was |

| ``Py_SSIZE_T_MAX``. Patch by Xiang Zhang. |
| |
| - Issue #27782: Multi-phase extension module import now correctly allows the |
| ``m_methods`` field to be used to add module level functions to instances |
| of non-module types returned from ``Py_create_mod``. Patch by Xiang Zhang. |
| |
| - Issue #27936: The round() function accepted a second None argument |
| for some types but not for others. Fixed the inconsistency by |
| accepting None for all numeric types. |

| Patch by Eryk Sun and Emanuel Barry. |
| |
| - Issue #27558: Fix a SystemError in the implementation of "raise" statement. |

| before DDL statements. |
| |
| - Issue #17941: Add a *module* parameter to collections.namedtuple(). |
| |

| an awaitable that resolves to an asynchronous iterator, the asynchronous |
| iterator should be returned directly. Doing the former will trigger a |
| PendingDeprecationWarning. |

| =================================== |
| |
| Release date: 2016-05-16 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #20041: Fixed TypeError when frame.f_trace is set to None. |
| Patch by Xavier de Gaye. |
| |
| - Issue #26168: Fixed possible refleaks in failing Py_BuildValue() with the "N" |
| format unit. |
| |
| - Issue #26991: Fix possible refleak when creating a function with annotations. |
| |
| - Issue #27039: Fixed bytearray.remove() for values greater than 127. Based on |
| patch by Joe Jevnik. |
| |
| - Issue #23640: int.from_bytes() no longer bypasses constructors for subclasses. |
| |
| - Issue #27005: Optimized the float.fromhex() class method for exact float. |
| It is now 2 times faster. |
| |
| - Issue #18531: Single var-keyword argument of dict subtype was passed |
| unscathed to the C-defined function. Now it is converted to exact dict. |
| |
| - Issue #26811: gc.get_objects() no longer contains a broken tuple with NULL |
| pointer. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #26659: Make the builtin slice type support cycle collection. |
| |
| - Issue #26718: super.__init__ no longer leaks memory if called multiple times. |
| NOTE: A direct call of super.__init__ is not endorsed! |
| |

| |
| - Issue #27147: Mention PEP 420 in the importlib docs. |
| |
| - Issue #25339: PYTHONIOENCODING now has priority over locale in setting the |
| error handler for stdin and stdout. |
| |
| - Issue #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. |
| |
| - Issue #26574: Optimize ``bytes.replace(b'', b'.')`` and |
| ``bytearray.replace(b'', b'.')``. Patch written by Josh Snider. |
| |
| - Issue #26581: If coding cookie is specified multiple times on a line in |
| Python source code file, only the first one is taken to account. |
| |
| - Issue #19711: Add tests for reloading namespace packages. |
| |
| - Issue #21099: Switch applicable importlib tests to use PEP 451 API. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #26558: The debug hooks on Python memory allocator |
| :c:func:`PyObject_Malloc` now detect when functions are called without |
| holding the GIL. |
| |
| - Issue #26516: Add :envvar:`PYTHONMALLOC` environment variable to set the |
| Python memory allocators and/or install debug hooks. |
| |
| - Issue #26516: The :c:func:`PyMem_SetupDebugHooks` function can now also be |
| used on Python compiled in release mode. |
| |
| - Issue #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. |
| |
| - Issue #26516: In debug mode, debug hooks are now also installed on Python |
| memory allocators when Python is configured without pymalloc. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #26302: Correct behavior to reject comma as a legal character for |
| cookie names. |
| |
| - Issue #26136: Upgrade the warning when a generator raises StopIteration |
| from PendingDeprecationWarning to DeprecationWarning. Patch by Anish |
| Shah. |
| |
| - Issue #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``. |
| |
| - Issue #4806: Avoid masking the original TypeError exception when using star |
| (*) unpacking in function calls. Based on patch by Hagen Fürstenau and |
| Daniel Urban. |
| |
| - Issue #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. |
| |
| - Issue #23601: Sped-up allocation of dict key objects by using Python's |
| small object allocator. (Contributed by Julian Taylor.) |
| |
| - Issue #18018: Import raises ImportError instead of SystemError if a relative |
| import is attempted without a known parent package. |
| |
| - Issue #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. |
| |
| - Issue #26107: The format of the ``co_lnotab`` attribute of code objects |
| changes to support negative line number delta. |
| |
| - Issue #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. |
| |
| - Issue #25791: If __package__ != __spec__.parent or if neither __package__ or |
| __spec__ are defined then ImportWarning is raised. |
| |
| - Issue #22995: [UPDATE] Comment out the one of the pickleability tests in |
| _PyObject_GetState() due to regressions observed in Cython-based projects. |

| |
| - Issue #25973: Fix segfault when an invalid nonlocal statement binds a name |
| starting with two underscores. |
| |
| - Issue #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. |
| |
| - Issue #20440: Massive replacing unsafe attribute setting code with special |
| macro Py_SETREF. |
| |
| - Issue #25766: Special method __bytes__() now works in str subclasses. |
| |
| - Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size. |
| This allows sys.getsize() to work correctly with their subclasses with |
| __slots__ defined. |
| |
| - Issue #25709: Fixed problem with in-place string concatenation and utf-8 |
| cache. |
| |
| - Issue #5319: New Py_FinalizeEx() API allowing Python to set an exit status |
| of 120 on failure to flush buffered streams. |
| |
| - Issue #25485: telnetlib.Telnet is now a context manager. |
| |
| - Issue #24097: Fixed crash in object.__reduce__() if slot name is freed inside |
| __getattr__. |
| |
| - Issue #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. |
| |
| - Issue #25630: Fix a possible segfault during argument parsing in functions |
| that accept filesystem paths. |
| |
| - Issue #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. |
| |
| - Issue #25388: Fixed tokenizer crash when processing undecodable source code |
| with a null byte. |
| |
| - Issue #25462: The hash of the key now is calculated only once in most |
| operations in C implementation of OrderedDict. |
| |
| - Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now |
| rejects builtin types with not defined __new__. |
| |
| - Issue #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. |
| |
| - Issue #25555: Fix parser and AST: fill lineno and col_offset of "arg" node |
| when compiling AST from Python objects. |
| |
| - Issue #24726: Fixed a crash and leaking NULL in repr() of OrderedDict that |
| was mutated by direct calls of dict methods. |
| |
| - Issue #25449: Iterating OrderedDict with keys with unstable hash now raises |
| KeyError in C implementations as well as in Python implementation. |
| |
| - Issue #25395: Fixed crash when highly nested OrderedDict structures were |
| garbage collected. |
| |
| - Issue #25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now |
| between 2x and 3.5x faster. |
| |
| - Issue #25399: Optimize bytearray % args using the new private _PyBytesWriter |
| API. Formatting is now between 2.5 and 5 times faster. |
| |
| - Issue #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. |
| |
| - Issue #24402: Fix input() to prompt to the redirected stdout when |
| sys.stdout.fileno() fails. |
| |
| - Issue #25349: Optimize bytes % args using the new private _PyBytesWriter API. |
| Formatting is now up to 2 times faster. |
| |
| - Issue #24806: Prevent builtin types that are not allowed to be subclassed from |
| being subclassed through multiple inheritance. |
| |
| - Issue #25301: The UTF-8 decoder is now up to 15 times as fast for error |
| handlers: ``ignore``, ``replace`` and ``surrogateescape``. |
| |
| - Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data. |
| |
| - Issue #25267: The UTF-8 encoder is now up to 75 times as fast for error |

| longer formatted twice. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #26478: Fix semantic bugs when using binary operators with dictionary |
| views and tuples. |

| IDLE |
| ---- |
| |
| - Issue #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. |
| |
| - Issue #25507: fix incorrect change in IOBinding that prevented printing. |
| Augment IOBinding htest to include all major IOBinding functions. |
| |
| - Issue #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'. |
| |
| - Issue #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. |
| |
| - Issue #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. |

| Patch by Mark Roseman. |
| |

| Consistently use the revised idleConf.CurrentTheme everywhere in idlelib. |
| |
| - Issue #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. |
| |
| - Issue #22726: Re-activate the config dialog help button with some content |
| about the other buttons and the new IDLE Dark theme. |
| |
| - Issue #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. |
| |
| - Issue #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'. |
| |
| - Issue #24820: Users can now set breakpoint colors in |
| Settings -> Custom Highlighting. Original patch by Mark Roseman. |
| |
| - Issue #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. |

| Patch by Mark Roseman. |
| |
| - Issue #25173: Associate tkinter messageboxes with a specific widget. |
| For Mac OSX, make them a 'sheet'. Patch by Mark Roseman. |
| |
| - Issue #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. |
| |
| - Issue #25225: Condense and rewrite Idle doc section on text colors. |
| |
| - Issue #21995: Explain some differences between IDLE and console Python. |
| |
| - Issue #22820: Explain need for *print* when running file from Idle editor. |
| |
| - Issue #25224: Doc: augment Idle feature list and no-subprocess section. |
| |
| - Issue #25219: Update doc for Idle command line options. |
| Some were missing and notes were not correct. |
| |
| - Issue #24861: Most of idlelib is private and subject to change. |
| Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__. |
| |
| - Issue #25199: Idle: add synchronization comments for future maintainers. |
| |
| - Issue #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. |
| |
| - Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6. |
| |
| - Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts). |
| |

| 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. |
| |
| - Issue #26194: Deque.insert() gave odd results for bounded deques that had |

| more than once. |
| |
| - Issue #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. |

| were concurrent. |
| |
| - Issue #25348: Added ``--pgo`` and ``--pgo-job`` arguments to |
| ``PCbuild\build.bat`` for building with Profile-Guided Optimization. The |

| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #25709: Fixed problem with in-place string concatenation and |
| utf-8 cache. |
| |
| Windows |
| ------- |
| |
| - Issue #25715: Python 3.5.1 installer shows wrong upgrade path and incorrect |
| logic for launcher detection. |
| |
| |
| What's New in Python 3.5.1 release candidate 1? |
| =============================================== |
| |
| Release date: 2015-11-22 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #25630: Fix a possible segfault during argument parsing in functions |
| that accept filesystem paths. |
| |
| - Issue #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. |
| |
| - Issue #25388: Fixed tokenizer crash when processing undecodable source code |
| with a null byte. |
| |
| - Issue #25462: The hash of the key now is calculated only once in most |
| operations in C implementation of OrderedDict. |
| |
| - Issue #22995: Default implementation of __reduce__ and __reduce_ex__ now |
| rejects builtin types with not defined __new__. |
| |
| - Issue #25555: Fix parser and AST: fill lineno and col_offset of "arg" node |
| when compiling AST from Python objects. |
| |
| - Issue #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. |
| |
| - Issue #24726: Fixed a crash and leaking NULL in repr() of OrderedDict that |
| was mutated by direct calls of dict methods. |
| |
| - Issue #25449: Iterating OrderedDict with keys with unstable hash now raises |
| KeyError in C implementations as well as in Python implementation. |
| |
| - Issue #25395: Fixed crash when highly nested OrderedDict structures were |
| garbage collected. |
| |
| - Issue #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. |
| |
| - Issue #24402: Fix input() to prompt to the redirected stdout when |
| sys.stdout.fileno() fails. |
| |
| - Issue #24806: Prevent builtin types that are not allowed to be subclassed from |
| being subclassed through multiple inheritance. |
| |
| - Issue #24848: Fixed a number of bugs in UTF-7 decoding of misformed data. |
| |
| - Issue #25280: Import trace messages emitted in verbose (-v) mode are no |
| longer formatted twice. |
| |
| - Issue #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. |
| |
| - Issue #25182: The stdprinter (used as sys.stderr before the io module is |
| imported at startup) now uses the backslashreplace error handler. |
| |
| - Issue #25131: Make the line number and column offset of set/dict literals and |
| comprehensions correspond to the opening brace. |
| |
| - Issue #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 incompatibilies. |
| |
| Library |
| ------- |
| |
| - Issue #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. |
| |
| - Issue #25583: Avoid incorrect errors raised by os.makedirs(exist_ok=True) |
| when the OS gives priority to errors such as EACCES over EEXIST. |
| |
| - Issue #25593: Change semantics of EventLoop.stop() in asyncio. |
| |
| - Issue #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. |
| |
| - Issue #25590: In the Readline completer, only call getattr() once per |
| attribute. |
| |
| - Issue #25498: Fix a crash when garbage-collecting ctypes objects created |

| at the end if the FileInput was opened with binary mode. |
| Patch by Ryosuke Ito. |
| |
| - Issue #25503: Fixed inspect.getdoc() for inherited docstrings of properties. |
| Original patch by John Mark Vandenberg. |
| |
| - Issue #25515: Always use os.urandom as a source of randomness in uuid.uuid4. |
| |
| - Issue #21827: Fixed textwrap.dedent() for the case when largest common |
| whitespace is a substring of smallest leading whitespace. |
| Based on patch by Robert Li. |
| |

| |
| - Issue #25441: asyncio: Raise error from drain() when socket is closed. |
| |

| the email package. Thanks to user simon04 for the patch. |
| |
| - Issue #25407: Remove mentions of the formatter module being removed in |
| Python 3.6. |
| |
| - Issue #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. |
| |
| - Issue #25364: zipfile now works in threads disabled builds. |
| |
| - Issue #25328: smtpd's SMTPChannel now correctly raises a ValueError if both |
| decode_data and enable_SMTPUTF8 are set to true. |
| |
| - Issue #25316: distutils raises OSError instead of DistutilsPlatformError |
| when MSVC is not installed. |
| |
| - Issue #25380: Fixed protocol for the STACK_GLOBAL opcode in |
| pickletools.opcodes. |
| |
| - Issue #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. |
| |
| - Issue #25304: Add asyncio.run_coroutine_threadsafe(). This lets you |
| submit a coroutine to a loop from another thread, returning a |
| concurrent.futures.Future. By Vincent Michel. |
| |
| - Issue #25232: Fix CGIRequestHandler to split the query from the URL at the |
| first question mark (?) rather than the last. Patch from Xiang Zhang. |
| |
| - Issue #24657: Prevent CGIRequestHandler from collapsing slashes in the |
| query part of the URL as if it were a path. Patch from Xiang Zhang. |
| |

| argument. |
| |
| - Issue #25111: Fixed comparison of traceback.FrameSummary. |
| |
| - Issue #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. |
| |
| - Issue #25034: Fix string.Formatter problem with auto-numbering and |
| nested format_specs. Patch by Anthon van der Neut. |
| |
| - Issue #25233: Rewrite the guts of asyncio.Queue and |
| asyncio.Semaphore to be more understandable and correct. |
| |
| - Issue #25203: Failed readline.set_completer_delims() no longer left the |
| module in inconsistent state. |
| |
| - Issue #23600: Default implementation of tzinfo.fromutc() was returning |
| wrong results in some cases. |
| |
| - Issue #23329: Allow the ssl module to be built with older versions of |
| LibreSSL. |
| |
| - Prevent overflow in _Unpickler_Read. |
| |
| - Issue #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. |
| |
| - Issue #25135: Make deque_clear() safer by emptying the deque before clearing. |
| This helps avoid possible reentrancy issues. |
| |
| - Issue #19143: platform module now reads Windows version from kernel32.dll to |
| avoid compatibility shims. |
| |
| - Issue #25092: Fix datetime.strftime() failure when errno was already set to |
| EINVAL. |
| |
| - Issue #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. |
| |
| - Issue #25155: Fix datetime.datetime.now() and datetime.datetime.utcnow() on |
| Windows to support date after year 2038. It was a regression introduced in |
| Python 3.5.0. |
| |
| - Issue #25108: Omitted internal frames in traceback functions print_stack(), |
| format_stack(), and extract_stack() called without arguments. |
| |
| - Issue #25118: Fix a regression of Python 3.5.0 in os.waitpid() on Windows. |
| |
| - Issue #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. |
| |
| - Issue #25060: Correctly compute stack usage of the BUILD_MAP opcode. |
| |
| - Issue #24857: Comparing call_args to a long sequence now correctly returns a |
| boolean result instead of raising an exception. Patch by A Kaptur. |
| |
| - Issue #23144: Make sure that HTMLParser.feed() returns all the data, even |
| when convert_charrefs is True. |
| |
| - Issue #24982: shutil.make_archive() with the "zip" format now adds entries |
| for directories (including empty directories) in ZIP file. |

| in an infinite loop. Patch by Xavier de Gaye. |
| |
| - Issue #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. |
| |
| - Issue #24992: Fix error handling and a race condition (related to garbage |
| collection) in collections.OrderedDict constructor. |
| |

| - Issue #25569: Fix memory leak in SSLSocket.getpeercert(). |
| |
| - Issue #25471: Sockets returned from accept() shouldn't appear to be |
| nonblocking. |
| |
| - Issue #25319: When threading.Event is reinitialized, the underlying condition |
| should use a regular lock rather than a recursive lock. |
| |
| - Issue #21112: Fix regression in unittest.expectedFailure on subclasses. |
| Patch from Berker Peksag. |

| IDLE |
| ---- |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #24750: Improve the appearance of the IDLE editor window status bar. |
| Patch by Mark Roseman. |
| |
| - Issue #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. |
| |
| - Issue #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. |
| |
| - Issue #22726: Re-activate the config dialog help button with some content |
| about the other buttons and the new IDLE Dark theme. |
| |
| - Issue #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. |
| |
| - Issue #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'. |
| |
| - Issue #24820: Users can now set breakpoint colors in |
| Settings -> Custom Highlighting. Original patch by Mark Roseman. |
| |
| - Issue #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. |
| |
| - Issue #24570: Idle: make calltip and completion boxes appear on Macs |
| affected by a tk regression. Initial patch by Mark Roseman. |
| |
| - Issue #24988: Idle ScrolledList context menus (used in debugger) |
| now work on Mac Aqua. Patch by Mark Roseman. |
| |
| - Issue #24801: Make right-click for context menu work on Mac Aqua. |
| Patch by Mark Roseman. |
| |
| - Issue #25173: Associate tkinter messageboxes with a specific widget. |
| For Mac OSX, make them a 'sheet'. Patch by Mark Roseman. |
| |
| - Issue #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. |
| |
| - Issue #25225: Condense and rewrite Idle doc section on text colors. |
| |
| - Issue #21995: Explain some differences between IDLE and console Python. |
| |
| - Issue #22820: Explain need for *print* when running file from Idle editor. |
| |
| - Issue #25224: Doc: augment Idle feature list and no-subprocess section. |
| |
| - Issue #25219: Update doc for Idle command line options. |
| Some were missing and notes were not correct. |
| |
| - Issue #24861: Most of idlelib is private and subject to change. |
| Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__. |
| |
| - Issue #25199: Idle: add synchronization comments for future maintainers. |
| |
| - Issue #16893: Replace help.txt with help.html for Idle doc display. |
| The new idlelib/help.html is rstripped Doc/build/html/library/idle.html. |

| |
| - Issue #21859: Added Python implementation of io.FileIO. |

| - Issue #14260: The groupindex attribute of regular expression pattern object |
| now is non-modifiable mapping. |
| |
| - Issue #23792: Ignore KeyboardInterrupt when the pydoc pager is active. |
| This mimics the behavior of the standard unix pagers, and prevents |

| and socket open until the garbage collector cleans them up. Patch by |
| Martin Panter. |

| insert(), and copy(). This allows deques to be registered as a |
| MutableSequence and it improves their substitutability for lists. |
| |
| - Issue #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. |

| importing a test module is now picklable. |
| |
| - Issue #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. |
| |
| - Issue #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. |

| imp.reload(). Patch by Thomas Kluyver. |
| |
| - Issue #23605: os.walk() now calls os.scandir() instead of os.listdir(). |

| 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. |
| |
| - Issue #21669: With the aid of heuristics in SyntaxError.__init__, the |

| engine friendly) error messages when "exec" and "print" are used as |
| statements. |
| |

| trash a bad pointer dereference could occur due to a subtle flaw in |
| internal iteration logic. |

| All functions now raise BufferError in that case. |
| |
| - Issue #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. |
| |
| - Issue #22079: PyType_Ready() now checks that statically allocated type has |
| no dynamically allocated bases. |
| |
| - Issue #22453: Removed non-documented macro PyObject_REPR(). |
| |
| - Issue #18395: Rename ``_Py_char2wchar()`` to :c:func:`Py_DecodeLocale`, |
| rename ``_Py_wchar2char()`` to :c:func:`Py_EncodeLocale`, and document |
| these functions. |
| |
| - Issue #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. |
| |
| - Issue #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 |
| ------------- |

| as legacy links from the distutils docs, as they still contain some |
| required reference material for tool developers that isn't recorded |
| anywhere else. |
| |
| - Issue #19697: Document cases where __main__.__spec__ is None. |
