| What's New in Python 3.7.0 alpha 1? | |
| =================================== | |
| *Release date: XXXX-XX-XX* | |
| Core and Builtins | |
| ----------------- | |
| - 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-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. | |
| - 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 | |
| - Issue #29319: Prevent RunMainFromImporter overwriting sys.path[0]. | |
| - Issue #29337: Fixed possible BytesWarning when compare the code objects. | |
| Warnings could be emitted at compile time. | |
| - Issue #29327: Fixed a crash when pass the iterable keyword argument to | |
| sorted(). | |
| - Issue #29034: Fix memory leak and use-after-free in os module (path_converter). | |
| - Issue #29159: Fix regression in bytes(x) when x.__index__() raises Exception. | |
| - Issue #29049: Call _PyObject_GC_TRACK() lazily when calling Python function. | |
| Calling function is up to 5% faster. | |
| - Issue #28927: bytes.fromhex() and bytearray.fromhex() now ignore all ASCII | |
| whitespace, not only spaces. Patch by Robert Xiao. | |
| - Issue #28932: Do not include <sys/random.h> if it does not exist. | |
| - Issue #25677: Correct the positioning of the syntax error caret for | |
| indented blocks. Based on patch by Michael Layzell. | |

| - Issue #18896: Python function can now have more than 255 parameters. | |
| collections.namedtuple() now supports tuples with more than 255 elements. | |
| - Issue #28596: The preferred encoding is UTF-8 on Android. Patch written by | |
| Chi Hsuan Yen. | |
| - Issue #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. | |
| - Issue #28991: functools.lru_cache() was susceptible to an obscure reentrancy | |
| bug triggerable by a monkey-patched len() function. | |
| - Issue #28147: Fix a memory leak in split-table dictionaries: setattr() | |
| must not convert combined table into split table. Patch written by INADA | |
| Naoki. | |
| - Issue #28739: f-string expressions are no longer accepted as docstrings and | |
| by ast.literal_eval() even if they do not include expressions. | |
| - Issue #28512: Fixed setting the offset attribute of SyntaxError by | |
| PyErr_SyntaxLocationEx() and PyErr_SyntaxLocationObject(). | |
| - Issue #28918: Fix the cross compilation of xxlimited when Python has been | |
| built with Py_DEBUG defined. | |
| - Issue #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()``. | |
| - Issue #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. | |
| - Issue #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. | |
| - Issue #12844: More than 255 arguments can now be passed to a function. | |
| - Issue #28782: Fix a bug in the implementation ``yield from`` when checking | |
| if the next instruction is YIELD_FROM. Regression introduced by WORDCODE | |
| (issue #26647). | |
| - Issue #28774: Fix error position of the unicode error in ASCII and Latin1 | |

| - Issue #28731: Optimize _PyDict_NewPresized() to create correct size dict. | |
| Improve speed of dict literal with constant keys up to 30%. | |
| - Issue #28532: Show sys.version when -V option is supplied twice. | |
| - Issue #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. | |
| - Issue #28746: Fix the set_inheritable() file descriptor method on platforms | |
| that do not have the ioctl FIOCLEX and FIONCLEX commands. | |

| 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. | |
| - Issue #27080: Implement formatting support for PEP 515. Initial patch | |
| 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. | |
| - Issue #25758: Prevents zipimport from unnecessarily encoding a filename | |
| (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. | |
| - Issue #27999: Make "global after use" a SyntaxError, and ditto for nonlocal. | |
| Patch by Ivan Levkivskyi. | |
| - Issue #28003: Implement PEP 525 -- Asynchronous Generators. | |
| - Issue #27985: Implement PEP 526 -- Syntax for Variable Annotations. | |
| Patch by Ivan Levkivskyi. | |
| - Issue #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. | |
| - Issue #27364: A backslash-character pair that is not a valid escape sequence | |
| now generates a DeprecationWarning. Patch by Emanuel Barry. | |
| - Issue #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.) | |
| - Issue #27911: Remove unnecessary error checks in | |
| ``exec_builtin_or_dynamic()``. | |
| - Issue #27078: Added BUILD_STRING opcode. Optimized f-strings evaluation. | |
| - Issue #17884: Python now requires systems with inttypes.h and stdint.h | |
| - 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. | |
| Thanks Oren Milman for analysis and patch. | |
| - Issue #27506: Support passing the bytes/bytearray.translate() "delete" | |
| argument by keyword. | |
| - Issue #27812: Properly clear out a generator's frame's backreference to the | |
| generator to prevent crashes in frame.clear(). | |
| - Issue #27811: Fix a crash when a coroutine that has not been awaited is | |
| finalized with warnings-as-errors enabled. | |
| - Issue #27587: Fix another issue found by PVS-Studio: Null pointer check | |
| after use of 'def' in _PyState_AddModule(). | |
| Initial patch by Christian Heimes. | |
| - Issue #27792: The modulo operation applied to ``bool`` and other | |
| ``int`` subclasses now always returns an ``int``. Previously | |
| the return type depended on the input values. Patch by Xiang Zhang. | |
| - Issue #26984: int() now always returns an instance of exact int. | |
| - Issue #25604: Fix a minor bug in integer true division; this bug could | |
| potentially have caused off-by-one-ulp results on platforms with | |
| 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 | |
| checking against ``Py_SIZE_MAX`` instead of the correct upper bound of | |
| ``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. | |
| - Issue #27487: Warn if a submodule argument to "python -m" or | |
| runpy.run_module() is found in sys.modules after parent packages are | |
| imported, but before the submodule is executed. | |
| - Issue #27157: Make only type() itself accept the one-argument form. | |
| Patch by Eryk Sun and Emanuel Barry. | |
| - Issue #27558: Fix a SystemError in the implementation of "raise" statement. | |
| In a brand new thread, raise a RuntimeError since there is no active | |
| exception to reraise. Patch written by Xiang Zhang. | |
| - Issue #28008: Implement PEP 530 -- asynchronous comprehensions. | |

| before DDL statements. | |
| - Issue #17941: Add a *module* parameter to collections.namedtuple(). | |
| - Issue #22493: Inline flags now should be used only at the start of the | |
| regular expression. Deprecation warning is emitted if uses them in the | |
| middle of the regular expression. | |
| - Issue #26885: xmlrpc now supports unmarshalling additional data types used | |
| by Apache XML-RPC implementation for numerics and None. | |

| deprecation include manual creation of SSLSocket and certfile/keyfile | |
| (or similar) in ftplib, httplib, imaplib, smtplib, poplib and urllib. | |
| - Issue #28043: SSLContext has improved default settings: OP_NO_SSLv2, | |
| OP_NO_SSLv3, OP_NO_COMPRESSION, OP_CIPHER_SERVER_PREFERENCE, | |
| OP_SINGLE_DH_USE, OP_SINGLE_ECDH_USE and HIGH ciphers without MD5. | |

| have been reorganized and rewritten to emphasize the new API. | |
| - Issue #22450: urllib now includes an ``Accept: */*`` header among the | |
| default headers. This makes the results of REST API requests more | |
| consistent and predictable especially when proxy servers are involved. | |

| (Previously, this mechanism existed only for __hash__, to make | |
| mutable classes unhashable.) Code contributed by Andrew Barnert and | |
| Ivan Levkivskyi. | |

| 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. | |
| - Issue #26243: Only the level argument to zlib.compress() is keyword argument | |
| now. The first argument is positional-only. | |

| encoded as an iterable of integers. Now only strings and byte-like objects | |
| are accepted. | |

| 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. | |
| - [Security] Issue #27278: Fix os.urandom() implementation using getrandom() on | |
| Linux. Truncate size to INT_MAX and loop until we collected enough random | |

| Library | |
| ------- | |
| - Comment out socket (SO_REUSEPORT) and posix (O_SHLOCK, O_EXLOCK) constants | |

| What's New in Python 3.6.0 alpha 1? | |
| =================================== | |
| 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 #27138: Fix the doc comment for FileFinder.find_spec(). | |
| - 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 #25961: Disallowed null characters in the type name. | |
| - 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 | |
| handlers: ``ignore``, ``replace``, ``surrogateescape``, ``surrogatepass``. | |
| Patch co-written with Serhiy Storchaka. | |
| - Issue #25280: Import trace messages emitted in verbose (-v) mode are no | |
| 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. | |

| - Issues #26289 and #26315: Optimize floor and modulo division for | |
| single-digit longs. Microbenchmarks show 2-2.5x improvement. Built-in | |
| 'divmod' function is now also ~10% faster. | |
| - Issue #25887: Raise a RuntimeError when a coroutine object is awaited | |
| more than once. | |
| Library | |
| ------- | |
| - Issue #27057: Fix os.set_inheritable() on Android, ioctl() is blocked by | |
| SELinux and fails with EACCESS. The function now falls back to fcntl(). | |

| a query string. Original fix by Ján Janech. | |
| - Issue #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. | |
| - Issue #27033: The default value of the decode_data parameter for | |
| smtpd.SMTPChannel and smtpd.SMTPServer constructors is changed to False. | |
| - Issue #27034: Removed deprecated class asynchat.fifo. | |

| being automatically added to the history list. Based on patch by Tyler | |
| Crompton. | |
| - Issue #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. | |

| Patch by Georg Brandl. | |
| - Issue #26873: xmlrpc now raises ResponseError on unsupported type tags | |
| instead of silently return incorrect result. | |
| - Issue #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. | |
| - Issue #26711: Fixed the comparison of plistlib.Data with other types. | |
| - Issue #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. | |
| - Issue #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. | |
| - Issue #24902: Print server URL on http.server startup. Initial patch by | |
| Felix Kaiser. | |
| - Issue #25788: fileinput.hook_encoded() now supports an "errors" argument | |
| for passing to open. Original patch by Joseph Hackman. | |

| Xiang Zhang. | |
| - Issue #26804: urllib.request will prefer lower_case proxy environment | |
| variables over UPPER_CASE or Mixed_Case ones. Patch contributed by Hans-Peter | |
| Jansen. | |
| - Issue #26837: assertSequenceEqual() now correctly outputs non-stringified | |
| differing items (like bytes in the -b mode). This affects assertListEqual() | |
| and assertTupleEqual(). | |

| :exc:`AttributeError` instead of :exc:`NameError`. Patch written by Emanuel | |
| Barry. | |
| - Issue #24838: tarfile's ustar and gnu formats now correctly calculate name | |
| and link field limits for multibyte character encodings like utf-8. | |
| - [Security] Issue #26657: Fix directory traversal vulnerability with | |
| http.server on Windows. This fixes a regression that was introduced in | |

| large" if there are too many header fields to parse, rather than killing | |
| the connection and raising an unhandled exception. Patch by Xiang Zhang. | |
| - Issue #26676: Added missing XMLPullParser to ElementTree.__all__. | |
| - Issue #22854: Change BufferedReader.writable() and | |
| BufferedWriter.readable() to always return False. | |
| - Issue #26492: Exhausted iterator of array.array now conforms with the behavior | |
| of iterators of other mutable sequences: it lefts exhausted even if iterated | |
| array is extended. | |
| - Issue #26641: doctest.DocFileTest and doctest.testfile() now support | |
| packages (module splitted into multiple directories) for the package | |
| parameter. | |

| 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 #23883: Added missing APIs to __all__ to match the documented APIs | |
| for the following modules: calendar, csv, enum, fileinput, ftplib, logging, | |
| optparse, tarfile, threading and wave. Also added a | |
| test.support.check__all__() helper. Patches by Jacek Kołodziej, Mauro | |
| S. M. Rodrigues and Joel Taddei. | |

| 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. | |
| - Issue #25313: Change the handling of new built-in text color themes to better | |

| 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. | |
| 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). | |

| What's New in Python 3.5.2 release candidate 1? | |
| =============================================== | |
| Release date: 2016-06-12 | |
| Core and Builtins | |
| ----------------- | |
| - Issue #27066: Fixed SystemError if a custom opener (for open()) returns a | |
| negative number without setting an exception. | |
| - 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. Patch by | |
| Joe Jevnik. | |
| - Issue #23640: int.from_bytes() no longer bypasses constructors for subclasses. | |
| - 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 #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 #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 #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 #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 #4806: Avoid masking the original TypeError exception when using star | |
| (``*``) unpacking in function calls. Based on patch by Hagen Fürstenau and | |
| Daniel Urban. | |
| - Issue #27138: Fix the doc comment for FileFinder.find_spec(). | |
| - 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 #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. | |
| - 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`` (``int``), even if ``1`` and ``1.0`` | |
| are equal. | |
| - Issue #22995: [UPDATE] Comment out the one of the pickleability tests in | |
| _PyObject_GetState() due to regressions observed in Cython-based projects. | |
| - Issue #25961: Disallowed null characters in the type name. | |
| - 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. | |

| cache. | |
| - Issue #27147: Mention PEP 420 in the importlib docs. | |

| __bytes__, __trunc__, and __float__ returning instances of subclasses of | |
| bytes, int, and float to subclasses of bytes, int, and float correspondingly. | |
| - Issue #26478: Fix semantic bugs when using binary operators with dictionary | |
| views and tuples. | |
| - Issue #26171: Fix possible integer overflow and heap corruption in | |
| zipimporter.get_data(). | |

| 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. | |

| - Issue #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. | |
| - Issue #26892: Honor debuglevel flag in urllib.request.HTTPHandler. Patch | |
| contributed by Chi Hsuan Yen. | |

| - Issue #19771: Also in runpy and the "-m" option, omit the irrelevant | |
| message ". . . is a package and cannot be directly executed" if the package | |
| could not even be initialized (e.g. due to a bad ``*.pyc`` file). | |

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

| ================================= | |
| Release date: 2015-12-06 | |
| 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 | |
| by wrapping a memoryview. This was a regression made in 3.5a1. Based | |
| on patch by Eryksun. | |

| 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 #25447: The lru_cache() wrapper objects now can be copied and pickled | |
| (by returning the original object unchanged). | |
| - Issue #25390: typing: Don't crash on Union[str, Pattern]. | |
| - Issue #25441: asyncio: Raise error from drain() when socket is closed. | |
| - Issue #25410: Cleaned up and fixed minor bugs in C implementation of | |
| OrderedDict. | |

| 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. | |
| - Issue #24483: C implementation of functools.lru_cache() now calculates key's | |

| 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 | |

| - 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 | |

| 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. | |

| of stdin (0), stdout (1) or stderr (2) is closed while Python is creating | |

| 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. | |

| Patch by Mark Roseman. | |
| - Issue #25313: Change the handling of new built-in text color themes to better | |

| 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 #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 Mark 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). | |

| language reference. Some of the details of comparing mixed types were | |
| incorrect or ambiguous. NotImplemented is only relevant at a lower level | |
| than the Expressions chapter. Added details of comparing range() objects, | |
| and default behaviour and consistency suggestions for user-defined classes. | |

| if Argument Clinic processes the same symbol multiple times, and it's emitted | |
| at the end of all processing rather than immediately after the first use. | |

| Original patch by Wolfgang Maier. | |
| - Issue #23252: Added support for writing ZIP files to unseekable streams. | |
| - Issue #23647: Increase impalib's MAXLINE to accommodate modern mailbox sizes. | |
| - Issue #23539: If body is None, http.client.HTTPConnection.request now sets | |
| Content-Length to 0 for PUT, POST, and PATCH headers to avoid 411 errors from | |
| some web servers. | |
| - Issue #22351: The nntplib.NNTP constructor no longer leaves the connection | |
| and socket open until the garbage collector cleans them up. Patch by | |
| Martin Panter. | |
| - Issue #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. | |
| - 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. | |
| - Issue #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. | |
| - Issue #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). | |
| - Issue #23136: _strptime now uniformly handles all days in week 0, including | |
| Dec 30 of previous year. Based on patch by Jim Carroll. | |
| - Issue #23700: Iterator of NamedTemporaryFile now keeps a reference to | |
| NamedTemporaryFile instance. Patch by Bohuslav Kabrda. | |
| - Issue #22903: The fake test case created by unittest.loader when it fails | |
| 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. | |
| 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. | |

| handle exceptions raised by an iterator. Patch by Alon Diamant and Davin | |
| Potts. | |
| - Issue #23581: Add matmul support to MagicMock. Patch by Håkan Lövdahl. | |
| - Issue #23566: enable(), register(), dump_traceback() and | |
| dump_traceback_later() functions of faulthandler now accept file | |
| descriptors. Patch by Wei Wu. | |
| - Issue #22928: Disabled HTTP header injections in http.client. | |
| Original patch by Demian Brecht. | |
| - Issue #23615: Modules bz2, tarfile and tokenize now can be reloaded with | |
| imp.reload(). Patch by Thomas Kluyver. | |
| - Issue #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. | |

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

| trash a bad pointer dereference could occur due to a subtle flaw in | |
| internal iteration logic. | |
| - Issue #21377: PyBytes_Concat() now tries to concatenate in-place when the | |

| - Issue #19655: The ASDL parser - used by the build process to generate code for | |
| managing the Python AST in C - was rewritten. The new parser is self contained | |
| and does not require to carry long the spark.py parser-generator library; | |
| spark.py was removed from the source base. | |

| - Issue #15759: "make suspicious", "make linkcheck" and "make doctest" in Doc/ | |
| now display special message when and only when there are failures. | |
| - Issue #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. | |
| - Issue #21037: Add a build option to enable AddressSanitizer support. | |
| - Issue #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. | |
| - Issue #21285: Refactor and fix curses configure check to always search | |
| in a ncursesw directory. | |
| - Issue #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. | |
| - Issue #17861: Tools/scripts/generate_opcode_h.py automatically regenerates | |
| Include/opcode.h from Lib/opcode.py if the latter gets any change. | |
| - Issue #20644: OS X installer build support for documentation build changes | |
| in 3.4.1: assume externally supplied sphinx-build is available in /usr/bin. | |
| - Issue #20022: Eliminate use of deprecated bundlebuilder in OS X builds. | |
| - Issue #15968: Incorporated Tcl, Tk, and Tix builds into the Windows build | |
| solution. | |
| - Issue #17095: Fix Modules/Setup *shared* support. | |
| - Issue #21811: Anticipated fixes to support OS X versions > 10.9. | |
| - Issue #21166: Prevent possible segfaults and other random failures of | |
| python --generate-posix-vars in pybuilddir.txt build target. | |
| - Issue #18096: Fix library order returned by python-config. | |
| - Issue #17219: Add library build dir for Python extension cross-builds. | |
| - Issue #22919: Windows build updated to support VC 14.0 (Visual Studio 2015), | |
| which will be used for the official release. | |
| - Issue #21236: Build _msi.pyd with cabinet.lib instead of fci.lib | |
| - Issue #17128: Use private version of OpenSSL for OS X 10.5+ installer. | |
| C API | |
| ----- | |
| - Issue #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. | |
| - 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 | |
| ------------- | |
| - Issue #19548: Update the codecs module documentation to better cover the | |
| distinction between text encodings and other codecs, together with other | |
| clarifications. Patch by Martin Panter. | |
| - Issue #22394: Doc/Makefile now supports ``make venv PYTHON=../python`` to | |
| create a venv for generating the documentation, e.g., | |
| ``make html PYTHON=venv/bin/python3``. | |
| - Issue #21514: The documentation of the json module now refers to new JSON RFC | |
| 7159 instead of obsoleted RFC 4627. | |
| - Issue #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. | |
| - Issue #6916: undocument deprecated asynchat.fifo class. | |
| - Issue #17386: Expanded functionality of the ``Doc/make.bat`` script to make | |
| it much more comparable to ``Doc/Makefile``. | |
| - Issue #21312: Update the thread_foobar.h template file to include newer | |
| threading APIs. Patch by Jack McCracken. | |
| - Issue #21043: Remove the recommendation for specific CA organizations and to | |
| mention the ability to load the OS certificates. | |
| - Issue #20765: Add missing documentation for PurePath.with_name() and | |
| PurePath.with_suffix(). | |
| - Issue #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. | |
| - Issue #19697: Document cases where __main__.__spec__ is None. | |
| Tests | |
| ----- | |

| loaded from test modules that don't define test_main(). | |
| - Issue #22111: Assorted cleanups in test_imaplib. Patch by Milan Oberkirch. | |
| - Issue #22002: Added ``load_package_tests`` function to test.support and used | |
| it to implement/augment test discovery in test_asyncio, test_email, | |
| test_importlib, test_json, and test_tools. | |
| - Issue #21976: Fix test_ssl to accept LibreSSL version strings. Thanks | |

| version to 1.2. Patch written by Lennart Regebro. | |
| - Issue #21605: Added tests for Tkinter images. | |
| - Issue #21493: Added test for ntpath.expanduser(). Original patch by | |
| Claudiu Popa. | |

| ----------- | |
| - Issue #22314: pydoc now works when the LINES environment variable is set. | |

| ------- | |
| - Issue #23260: Update Windows installer | |
| - The bundled version of Tcl/Tk has been updated to 8.6.3. The most visible | |
| result of this change is the addition of new native file dialogs when | |
