| What's New in Python 3.5.2 release candidate 1? |
| =============================================== |
| |
| Release date: tba |
| |
| Core and Builtins |
| ----------------- |
| |
| - 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 #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 #25731: Fix set and deleting __new__ on a class. |
| |
| - 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 #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 #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(). |
| |
| - Issue #25660: Fix TAB key behaviour in REPL with readline. |
| |
| - Issue #25887: Raise a RuntimeError when a coroutine object is awaited |
| more than once. |
| |

| |
| - Issue #22854: Change BufferedReader.writable() and |
| BufferedWriter.readable() to always return False. |
| |
| - Issue #25195: Fix a regression in mock.MagicMock. _Call is a subclass of |
| tuple (changeset 3603bae63c13 only works for classes) so we need to |
| implement __ne__ ourselves. Patch by Andrew Plummer. |
| |
| - Issue #26644: Raise ValueError rather than SystemError when a negative |

| option if it is safe to do so. |
| |
| - Issue #22570: Add 'path' attribute to pathlib.Path objects, |
| returning the same as str(), to make it more similar to DirEntry. |
| Library code can now write getattr(p, 'path', p) to get the path as |

| essentially a small one-off protocol. |
| |
| - Issue #26012: Don't traverse into symlinks for ** pattern in |

| |
| - Issue #25860: os.fwalk() no longer skips remaining directories when error |

| |
| - Issue #25902: Fixed various refcount issues in ElementTree iteration. |
| |
| - Issue #25717: Restore the previous behaviour of tolerating most fstat() |
| errors when opening files. This was a regression in 3.5a1, and stopped |
| anonymous temporary files from working in special cases. |
| |
| - Issue #24903: Fix regression in number of arguments compileall accepts when |
| '-d' is specified. The check on the number of arguments has been dropped |
| completely as it never worked correctly anyway. |
| |
| - Issue #25764: In the subprocess module, preserve any exception caused by |
| fork() failure when preexec_fn is used. |
| |
| - Issue #6478: _strptime's regexp cache now is reset after changing timezone |
| with time.tzset(). |
| |
| - Issue #14285: When executing a package with the "python -m package" option, |
| and package initialization fails, a proper traceback is now reported. The |
| "runpy" module now lets exceptions from package initialization pass back to |
| the caller, rather than raising ImportError. |
| |
| - 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). |
| |
| - Issue #25177: Fixed problem with the mean of very small and very large |
| numbers. As a side effect, statistics.mean and statistics.variance should |
| be significantly faster. |
| |
| - Issue #25718: Fixed copying object with state with boolean value is false. |
| |
| - Issue #10131: Fixed deep copying of minidom documents. Based on patch |
| by Marian Ganisin. |

| invalid data including tuple instructions. |
| |
| - Issue #25663: In the Readline completer, avoid listing duplicate global |
| names, and search the global namespace before searching builtins. |

| |
| |
| 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. |
| |
| - Issue #25584: Added "escape" to the __all__ list in the glob module. |
| |
| - Issue #25584: Fixed recursive glob() with patterns starting with '\*\*'. |
| |
| - Issue #25446: Fix regression in smtplib's AUTH LOGIN support. |
| |
| - Issue #18010: Fix the pydoc web server's module search function to handle |
| exceptions from importing packages. |
| |
| - Issue #25554: Got rid of circular references in regular expression parsing. |
| |
| - Issue #25510: fileinput.FileInput.readline() now returns b'' instead of '' |
| 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. |
| |
| - Issue #25411: Improved Unicode support in SMTPHandler through better use of |
| the email package. Thanks to user simon04 for the patch. |
| |
| - Issue #25407: Remove mentions of the formatter module being removed in |
| Python 3.6. |
| |

| 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 |

| 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 |

| Patch by Mark Roseman. |

| 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 |

| * 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). |
| |

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

| |
| - Issue #23629: Fix the default __sizeof__ implementation for variable-sized |
| objects. |
| |
| Library |
| ------- |
| |
| - 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 |
| pipepager from shutting down while the pager itself is still running. |
| |
| - Issue #23775: pprint() of OrderedDict now outputs the same representation |
| as repr(). |
| |
| - Issue #23765: Removed IsBadStringPtr calls in ctypes |

| and ASCII letter now raise a deprecation warning and will be forbidden in |
| Python 3.6. |
| |

| |
| - Issue #17530: pprint now wraps long bytes objects and bytearrays. |

| supports copying of instances of classes whose __new__ method takes |
| keyword-only arguments. |
| |
| - Issue #23491: Added a zipapp module to support creating executable zip |
| file archives of Python code. Registered ".pyz" and ".pyzw" extensions |
| on Windows for these archives (PEP 441). |
| |
| - Issue #23657: Avoid explicit checks for str in zipapp, adding support |
| for pathlib.Path objects as arguments. |
| |
| - Issue #23688: Added support of arbitrary bytes-like objects and avoided |
| unnecessary copying of memoryview in gzip.GzipFile.write(). |
| Original patch by Wolfgang Maier. |

| 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 substitutablity 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. |

| codecs, that accepted only read-only bytes-like object now accept writable |
| bytes-like object too. |

| 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. |
| |

| |
| - 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. |

| 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 |

| editor window with a filename. When Class Browser is requested otherwise, |
| from a shell, output window, or 'Untitled' editor, Idle no longer displays |

| is entered and a module is opened, a corresponding browser is also opened. |
| |
| - Issue #4832: Save As to type Python files automatically adds .py to the |

| script. |
| |
| - Issue #22935: Allow the ssl module to be compiled if openssl doesn't support |
| SSL 3. |
| |
| - Issue #22592: Drop support of the Borland C compiler to build Python. The |
| distutils module still supports it to build extensions. |
| |
| - Issue #22591: Drop support of MS-DOS, especially of the DJGPP compiler |
| (MS-DOS port of GCC). |
| |
| - Issue #16537: Check whether self.extensions is empty in setup.py. Patch by |

| 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 later gets any change. |
| |

| 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 |

| |
| - Issue #19407: New package installation and distribution guides based on |

| 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. |
| |

| - Issue #18492: All resources are now allowed when tests are not run by |
| regrtest.py. |
| |
| - Issue #21634: Fix pystone micro-benchmark: use floor division instead of true |

| WriteTransport.set_write_buffer_size() calls _maybe_pause_protocol() |
| to consider pausing receiving if the watermark limits have changed; |
| fix _check_resolved_address() for IPv6 address; and other minor |
| improvements, along with multiple documentation updates. |
| |
| - Issue #20684: Fix inspect.getfullargspec() to not to follow __wrapped__ |
| chains. Make its behaviour consistent with bound methods first argument. |
| Patch by Nick Coghlan and Yury Selivanov. |
| |
| - Issue #20681: Add new error handling API in asyncio. New APIs: |
| loop.set_exception_handler(), loop.default_exception_handler(), and |
| loop.call_exception_handler(). |
| |
| - Issue #20673: Implement support for UNIX Domain Sockets in asyncio. |
| New APIs: loop.create_unix_connection(), loop.create_unix_server(), |
| streams.open_unix_connection(), and streams.start_unix_server(). |
| |
| - Issue #20616: Add a format() method to tracemalloc.Traceback. |
| |
| - Issue #19744: the ensurepip installation step now just prints a warning to |
| stderr rather than failing outright if SSL/TLS is unavailable. This allows |
| local installation of POSIX builds without SSL/TLS support. |
| |
| - Issue #20594: Avoid name clash with the libc function posix_close. |
| |
| Build |
| ----- |
| |
| - Issue #20641: Run MSI custom actions (pip installation, pyc compilation) |
| with the NoImpersonate flag, to support elevated execution (UAC). |
| |
| - Issue #20221: Removed conflicting (or circular) hypot definition when |
| compiled with VS 2010 or above. Initial patch by Tabrez Mohammed. |
| |
| - Issue #20609: Restored the ability to build 64-bit Windows binaries on |
| 32-bit Windows, which was broken by the change in issue #19788. |

| What's New in Python 3.4.0 release candidate 1? |
| =============================================== |
| |
| Release date: 2014-02-10 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #19255: The builtins module is restored to initial value before |
| cleaning other modules. The sys and builtins modules are cleaned last. |
| |
| - Issue #20588: Make Python-ast.c C89 compliant. |
| |
| - Issue #20437: Fixed 22 potential bugs when deleting objects references. |
| |
| - Issue #20500: Displaying an exception at interpreter shutdown no longer |
| risks triggering an assertion failure in PyObject_Str. |
| |
| - Issue #20538: UTF-7 incremental decoder produced inconsistent string when |
| input was truncated in BASE64 section. |
| |
| - Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the |
| internal codec marking system added for issue #19619 to throw LookupError |
| for known non-text encodings at stream construction time. The existing |
| output type checks remain in place to deal with unmarked third party |
| codecs. |
| |
| - Issue #17162: Add PyType_GetSlot. |
| |
| - Issue #20162: Fix an alignment issue in the siphash24() hash function which |
| caused a crash on PowerPC 64-bit (ppc64). |
| |
| Library |
| ------- |
| |
| - Issue #20530: The signatures for slot builtins have been updated |
| to reflect the fact that they only accept positional-only arguments. |
| |
| - Issue #20517: Functions in the os module that accept two filenames |
| now register both filenames in the exception on failure. |
| |
| - Issue #20563: The ipaddress module API is now considered stable. |
| |
| - Issue #14983: email.generator now always adds a line end after each MIME |
| boundary marker, instead of doing so only when there is an epilogue. This |
| fixes an RFC compliance bug and solves an issue with signed MIME parts. |
| |
| - Issue #20540: Fix a performance regression (vs. Python 3.2) when layering |
| a multiprocessing Connection over a TCP socket. For small payloads, Nagle's |
| algorithm would introduce idle delays before the entire transmission of a |
| message. |
| |
| - Issue #16983: the new email header parsing code will now decode encoded words |
| that are (incorrectly) surrounded by quotes, and register a defect. |
| |
| - Issue #19772: email.generator no longer mutates the message object when |
| doing a down-transform from 8bit to 7bit CTEs. |
| |
| - Issue #20536: the statistics module now correctly handle Decimal instances |
| with positive exponents |
| |
| - Issue #18805: the netmask/hostmask parsing in ipaddress now more reliably |
| filters out illegal values and correctly allows any valid prefix length. |
| |
| - Issue #20481: For at least Python 3.4, the statistics module will require |
| that all inputs for a single operation be of a single consistent type, or |
| else a mixed of ints and a single other consistent type. This avoids |
| some interoperability issues that arose with the previous approach of |
| coercing to a suitable common type. |
| |
| - Issue #20478: the statistics module now treats collections.Counter inputs |
| like any other iterable. |
| |
| - Issue #17369: get_filename was raising an exception if the filename |
| parameter's RFC2231 encoding was broken in certain ways. This was |
| a regression relative to python2. |
| |
| - Issue #20013: Some imap servers disconnect if the current mailbox is |
| deleted, and imaplib did not handle that case gracefully. Now it |
| handles the 'bye' correctly. |
| |
| - Issue #20531: Revert 3.4 version of fix for #19063, and apply the 3.3 |
| version. That is, do *not* raise an error if unicode is passed to |
| email.message.Message.set_payload. |
| |
| - Issue #20476: If a non-compat32 policy is used with any of the email parsers, |
| EmailMessage is now used as the factory class. The factory class should |
| really come from the policy; that will get fixed in 3.5. |
| |
| - Issue #19920: TarFile.list() no longer fails when outputs a listing |
| containing non-encodable characters. Based on patch by Vajrasky Kok. |
| |
| - Issue #20515: Fix NULL pointer dereference introduced by issue #20368. |
| |
| - Issue #19186: Restore namespacing of expat symbols inside the pyexpat module. |
| |
| - Issue #20053: ensurepip (and hence venv) are no longer affected by the |
| settings in the default pip configuration file. |
| |
| - Issue #20426: When passing the re.DEBUG flag, re.compile() displays the |
| debug output every time it is called, regardless of the compilation cache. |
| |
| - Issue #20368: The null character now correctly passed from Tcl to Python. |
| Improved error handling in variables-related commands. |
| |
| - Issue #20435: Fix _pyio.StringIO.getvalue() to take into account newline |
| translation settings. |
| |
| - tracemalloc: Fix slicing traces and fix slicing a traceback. |
| |
| - Issue #20354: Fix an alignment issue in the tracemalloc module on 64-bit |
| platforms. Bug seen on 64-bit Linux when using "make profile-opt". |
| |
| - Issue #17159: inspect.signature now accepts duck types of functions, |
| which adds support for Cython functions. Initial patch by Stefan Behnel. |
| |
| - Issue #18801: Fix inspect.classify_class_attrs to correctly classify |
| object.__new__ and object.__init__. |
| |
| - Fixed cmath.isinf's name in its argument parsing code. |
| |
| - Issue #20311, #20452: poll and epoll now round the timeout away from zero, |
| instead of rounding towards zero, in select and selectors modules: |
| select.epoll.poll(), selectors.PollSelector.poll() and |
| selectors.EpollSelector.poll(). For example, a timeout of one microsecond |
| (1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to |
| zero. However, the granularity property and asyncio's resolution feature |
| were removed again. |
| |
| - asyncio: Some refactoring; various fixes; add write flow control to |
| unix pipes; Future.set_exception() instantiates the exception |
| argument if it is a class; improved proactor pipe transport; support |
| wait_for(f, None); don't log broken/disconnected pipes; use |
| ValueError instead of assert for forbidden subprocess_{shell,exec} |
| arguments; added a convenience API for subprocess management; added |
| StreamReader.at_eof(); properly handle duplicate coroutines/futures |
| in gather(), wait(), as_completed(); use a bytearray for buffering |
| in StreamReader; and more. |
| |
| - Issue #20288: fix handling of invalid numeric charrefs in HTMLParser. |
| |
| - Issue #20424: Python implementation of io.StringIO now supports lone surrogates. |
| |
| - Issue #20308: inspect.signature now works on classes without user-defined |
| __init__ or __new__ methods. |
| |
| - Issue #20372: inspect.getfile (and a bunch of other inspect functions that |
| use it) doesn't crash with unexpected AttributeError on classes defined in C |
| without __module__. |
| |
| - Issue #20356: inspect.signature formatting uses '/' to separate |
| positional-only parameters from others. |
| |
| - Issue #20223: inspect.signature now supports methods defined with |
| functools.partialmethods. |
| |
| - Issue #19456: ntpath.join() now joins relative paths correctly when a drive |
| is present. |
| |
| - Issue #19077: tempfile.TemporaryDirectory cleanup no longer fails when |
| called during shutdown. Emitting resource warning in __del__ no longer fails. |
| Original patch by Antoine Pitrou. |
| |
| - Issue #20394: Silence Coverity warning in audioop module. |
| |
| - Issue #20367: Fix behavior of concurrent.futures.as_completed() for |
| duplicate arguments. Patch by Glenn Langford. |
| |
| - Issue #8260: The read(), readline() and readlines() methods of |
| codecs.StreamReader returned incomplete data when were called after |
| readline() or read(size). Based on patch by Amaury Forgeot d'Arc. |
| |
| - Issue #20105: the codec exception chaining now correctly sets the |
| traceback of the original exception as its __traceback__ attribute. |
| |
| - Issue #17481: inspect.getfullargspec() now uses inspect.signature() API. |
| |
| - Issue #15304: concurrent.futures.wait() can block forever even if |
| Futures have completed. Patch by Glenn Langford. |
| |
| - Issue #14455: plistlib: fix serializing integers in the range |
| of an unsigned long long but outside of the range of signed long long for |
| binary plist files. |
| |
| IDLE |
| ---- |
| |
| - Issue #20406: Use Python application icons for Idle window title bars. |
| Patch mostly by Serhiy Storchaka. |
| |
| - Update the python.gif icon for the Idle classbrowser and pathbowser |
| from the old green snake to the new blue and yellow snakes. |
| |
| - Issue #17721: Remove non-functional configuration dialog help button until we |
| make it actually gives some help when clicked. Patch by Guilherme Simões. |
| |
| Tests |
| ----- |
| |
| - Issue #20532: Tests which use _testcapi now are marked as CPython only. |
| |
| - Issue #19920: Added tests for TarFile.list(). Based on patch by Vajrasky Kok. |
| |
| - Issue #19990: Added tests for the imghdr module. Based on patch by |
| Claudiu Popa. |
| |
| - Issue #20474: Fix test_socket "unexpected success" failures on OS X 10.7+. |
| |
| Tools/Demos |
| ----------- |
| |
| - Issue #20530: Argument Clinic's signature format has been revised again. |
| The new syntax is highly human readable while still preventing false |
| positives. The syntax also extends Python syntax to denote "self" and |
| positional-only parameters, allowing inspect.Signature objects to be |
| totally accurate for all supported builtins in Python 3.4. |
| |
| - Issue #20456: Argument Clinic now observes the C preprocessor conditional |
| compilation statements of the C files it parses. When a Clinic block is |
| inside a conditional code, it adjusts its output to match, including |
| automatically generating an empty methoddef macro. |
| |
| - Issue #20456: Cloned functions in Argument Clinic now use the correct |
| name, not the name of the function they were cloned from, for text |
| strings inside generated code. |
| |
| - Issue #20456: Fixed Argument Clinic's test suite and "--converters" feature. |
| |
| - Issue #20456: Argument Clinic now allows specifying different names |
| for a parameter in Python and C, using "as" on the parameter line. |
| |
| - Issue #20326: Argument Clinic now uses a simple, unique signature to |
| annotate text signatures in docstrings, resulting in fewer false |
| positives. "self" parameters are also explicitly marked, allowing |
| inspect.Signature() to authoritatively detect (and skip) said parameters. |
| |
| - Issue #20326: Argument Clinic now generates separate checksums for the |
| input and output sections of the block, allowing external tools to verify |
| that the input has not changed (and thus the output is not out-of-date). |
| |
| Build |
| ----- |
| |
| - Issue #20465: Update SQLite shipped with OS X installer to 3.8.3. |
| |
| C-API |
| ----- |
| |
| - Issue #20517: Added new functions allowing OSError exceptions to reference |
| two filenames instead of one: PyErr_SetFromErrnoWithFilenameObjects() and |
| PyErr_SetExcFromWindowsErrWithFilenameObjects(). |
| |
| Documentation |
| ------------- |
| |
| - Issue #20488: Change wording to say importlib is *the* implementation of |
| import instead of just *an* implementation. |
| |
| - Issue #6386: Clarify in the tutorial that specifying a symlink to execute |
| means the directory containing the executed script and not the symlink is |
| added to sys.path. |
| |
| |
| What's New in Python 3.4.0 Beta 3? |
| ================================== |
| |
| Release date: 2014-01-26 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #20189: Four additional builtin types (PyTypeObject, |
| PyMethodDescr_Type, _PyMethodWrapper_Type, and PyWrapperDescr_Type) |
| have been modified to provide introspection information for builtins. |
| |
| - Issue #17825: Cursor "^" is correctly positioned for SyntaxError and |
| IndentationError. |
| |
| - Issue #2382: SyntaxError cursor "^" is now written at correct position in most |
| cases when multibyte characters are in line (before "^"). This still not |
| works correctly with wide East Asian characters. |
| |
| - Issue #18960: The first line of Python script could be executed twice when |
| the source encoding was specified on the second line. Now the source encoding |
| declaration on the second line isn't effective if the first line contains |
| anything except a comment. 'python -x' works now again with files with the |
| source encoding declarations, and can be used to make Python batch files |
| on Windows. |
| |
| Library |
| ------- |
| |
| - asyncio: Various improvements and small changes not all covered by |
| issues listed below. E.g. wait_for() now cancels the inner task if |
| the timeout occcurs; tweaked the set of exported symbols; renamed |
| Empty/Full to QueueEmpty/QueueFull; "with (yield from lock)" now |
| uses a separate context manager; readexactly() raises if not enough |
| data was read; PTY support tweaks. |
| |
| - Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum |
| between the resolution of the BaseEventLoop.time() method and the resolution |
| of the selector. The granuarility is used in the scheduler to round time and |
| deadline. |
| |
| - Issue #20311: selectors: Add a resolution attribute to BaseSelector. |
| |
| - Issue #20189: unittest.mock now no longer assumes that any object for |
| which it could get an inspect.Signature is a callable written in Python. |
| Fix courtesy of Michael Foord. |
| |
| - Issue #20317: ExitStack.__exit__ could create a self-referential loop if an |
| exception raised by a cleanup operation already had its context set |
| correctly (for example, by the @contextmanager decorator). The infinite |
| loop this caused is now avoided by checking if the expected context is |
| already set before trying to fix it. |
| |
| - Issue #20374: Fix build with GNU readline >= 6.3. |
| |
| - Issue #20262: Warnings are raised now when duplicate names are added in the |
| ZIP file or too long ZIP file comment is truncated. |

| empty mode. |
| |
| - Issue #20242: Fixed basicConfig() format strings for the alternative |
| formatting styles. Thanks to kespindler for the bug report and patch. |
| |
| - Issue #20246: Fix buffer overflow in socket.recvfrom_into. |
| |
| - Issues #20206 and #5803: Fix edge case in email.quoprimime.encode where it |
| truncated lines ending in a character needing encoding but no newline by |
| using a more efficient algorithm that doesn't have the bug. |
| |
| - Issue #19082: Working xmlrpc.server and xmlrpc.client examples. Both in |
| modules and in documentation. Initial patch contributed by Vajrasky Kok. |
| |
| - Issue #20138: The wsgiref.application_uri() and wsgiref.request_uri() |
| functions now conform to PEP 3333 when handle non-ASCII URLs. |
| |

| on the second line if the first line contains anything except a comment. |
| |
| - Issue #20078: Reading malformed zipfiles no longer hangs with 100% CPU |
| consumption. |
| |
| - Issue #20113: os.readv() and os.writev() now raise an OSError exception on |
| error instead of returning -1. |
| |
| - Issue #19719: Make importlib.abc.MetaPathFinder.find_module(), |
| PathEntryFinder.find_loader(), and Loader.load_module() use PEP 451 APIs to |
| help with backwards-compatibility. |
| |
| - Issue #20144: inspect.Signature now supports parsing simple symbolic |
| constants as parameter default values in __text_signature__. |
| |
| - Issue #20072: Fixed multiple errors in tkinter with wantobjects is False. |
| |
| - Issue #20229: Avoid plistlib deprecation warning in platform.mac_ver(). |
| |
| - Issue #14455: Fix some problems with the new binary plist support in plistlib. |
| |
| IDLE |
| ---- |
| |
| - Issue #17390: Add Python version to Idle editor window title bar. |
| Original patches by Edmond Burnett and Kent Johnson. |

| - Issue #18960: IDLE now ignores the source encoding declaration on the second |
| line if the first line contains anything except a comment. |
| |
| Tests |

| no longer specify min{row,col} > max{row,col}. |
| |
| - Issue #19804: The test_find_mac test in test_uuid is now skipped if the |
| ifconfig executable is not available. |
| |
| - Issue #19886: Use better estimated memory requirements for bigmem tests. |
| |

| "{dirname}/clinic/{basename}.h". |
| |
| - Issue #20390: Argument Clinic's "class" directive syntax has been extended |
| with two new required arguments: "typedef" and "type_object". |
| |
| - Issue #20390: Argument Clinic: If __new__ or __init__ functions didn't use |
| kwargs (or args), the PyArg_NoKeywords (or PyArg_NoPositional) calls |
| generated are only run when the type object is an exact match. |
| |
| - Issue #20390: Argument Clinic now fails if you have required parameters after |
| optional parameters. |
| |
| - Issue #20390: Argument Clinic converters now have a new template they can |
| inject code into: "modifiers". Code put there is run in the parsing |
| function after argument parsing but before the call to the impl. |
| |
| - Issue #20376: Argument Clinic now escapes backslashes in docstrings. |
| |
| - Issue #20381: Argument Clinic now sanity checks the default argument when |
| c_default is also specified, providing a nice failure message for |
| disallowed values. |
| |
| - Issue #20189: Argument Clinic now ensures that parser functions for |
| __new__ are always of type newfunc, the type of the tp_new slot. |
| Similarly, parser functions for __init__ are now always of type initproc, |
| the type of tp_init. |
| |
| - Issue #20189: Argument Clinic now suppresses the docstring for __new__ |
| and __init__ functions if no docstring is provided in the input. |
| |
| - Issue #20189: Argument Clinic now suppresses the "self" parameter in the |
| impl for @staticmethod functions. |
| |

| - Issue #20299: Argument Clinic custom converters may now change the default |
| value of c_default and py_default with a class member. |
| |
| - Issue #20287: Argument Clinic's output is now configurable, allowing |
| delaying its output or even redirecting it to a separate file. |
| |
| - Issue #20226: Argument Clinic now permits simple expressions |
| (e.g. "sys.maxsize - 1") as default values for parameters. |
| |
| - Issue #19936: Added executable bits or shebang lines to Python scripts which |
| requires them. Disable executable bits and shebang lines in test and |
| benchmark files in order to prevent using a random system python, and in |
| source files of modules which don't provide command line interface. Fixed |

| format unit. |
| |
| - Issue #20144: Argument Clinic now supports simple symbolic constants |
| as parameter default values. |
| |
| - Issue #20143: The line numbers reported in Argument Clinic errors are |
| now more accurate. |

| |
| What's New in Python 3.4.0 Beta 2? |
| ================================== |
| |
| Release date: 2014-01-05 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Issue #17432: Drop UCS2 from names of Unicode functions in python3.def. |
| |
| - Issue #19526: Exclude all new API from the stable ABI. Exceptions can be |
| made if a need is demonstrated. |
| |
| - Issue #19969: PyBytes_FromFormatV() now raises an OverflowError if "%c" |
| argument is not in range [0; 255]. |
| |
| - Issue #19995: %c, %o, %x, and %X now issue a DeprecationWarning on non-integer |
| input; reworded docs to clarify that an integer type should define both __int__ |
| and __index__. |
| |
| - Issue #19787: PyThread_set_key_value() now always set the value. In Python |
| 3.3, the function did nothing if the key already exists (if the current value |
| is a non-NULL pointer). |
| |
| - Issue #14432: Remove the thread state field from the frame structure. Fix a |
| crash when a generator is created in a C thread that is destroyed while the |
| generator is still used. The issue was that a generator contains a frame, and |
| the frame kept a reference to the Python state of the destroyed C thread. The |
| crash occurs when a trace function is setup. |
| |
| - Issue #19576: PyGILState_Ensure() now initializes threads. At startup, Python |
| has no concrete GIL. If PyGILState_Ensure() is called from a new thread for |
| the first time and PyEval_InitThreads() was not called yet, a GIL needs to be |
| created. |
| |
| - Issue #17576: Deprecation warning emitted now when __int__() or __index__() |
| return not int instance. |
| |
| - Issue #19932: Fix typo in import.h, missing whitespaces in function prototypes. |
| |
| - Issue #19736: Add module-level statvfs constants defined for GNU/glibc |
| based systems. |
| |
| - Issue #20097: Fix bad use of "self" in importlib's WindowsRegistryFinder. |

| odd behaviour based on user configuration settings |
| |

| without suffixes and submodules that use explicit relative imports or |
| otherwise rely on parent modules being correctly imported prior to |
| execution. |
| |
| - Issue #19921: When Path.mkdir() is called with parents=True, any missing |
| parent is created with the default permissions, ignoring the mode argument |

| was 7bit, and produce garbage output for the content. This now works. |
| A couple of other set_payload mishandlings of non-ASCII are also fixed. |
| In addition, calling set_payload with a string argument without |
| specifying a charset now raises an error (this is a new error in 3.4). |
| |
| - Issue #15475: Add __sizeof__ implementations for itertools objects. |
| |
| - Issue #19944: Fix importlib.find_spec() so it imports parents as needed |

| both using ~50% less cpu time this way. |
| |
| - Issue #19506: Use a memoryview to avoid a data copy when piping data |
| to stdin within subprocess.Popen.communicate. 5-10% less cpu usage. |

| What's New in Python 3.4.0 Beta 1? |
| ================================== |
| |
| Release date: 2013-11-24 |
| |
| Core and Builtins |
| ----------------- |
| |
| - Use the repr of a module name in more places in import, especially |
| exceptions. |
| |
| - Issue #19619: str.encode, bytes.decode and bytearray.decode now use an |
| internal API to throw LookupError for known non-text encodings, rather |
| than attempting the encoding or decoding operation and then throwing a |
| TypeError for an unexpected output type. (The latter mechanism remains |
| in place for third party non-text encodings) |
| |
| - Issue #19183: Implement PEP 456 'secure and interchangeable hash algorithm'. |
| Python now uses SipHash24 on all major platforms. |
| |
| - Issue #12892: The utf-16* and utf-32* encoders no longer allow surrogate code |
| points (U+D800-U+DFFF) to be encoded. The utf-32* decoders no longer decode |
| byte sequences that correspond to surrogate code points. The surrogatepass |
| error handler now works with the utf-16* and utf-32* codecs. Based on |
| patches by Victor Stinner and Kang-Hao (Kenny) Lu. |
| |
| - Issue #17806: Added keyword-argument support for "tabsize" to |
| str/bytes.expandtabs(). |
| |
| - Issue #17828: Output type errors in str.encode(), bytes.decode() and |
| bytearray.decode() now direct users to codecs.encode() or codecs.decode() |
| as appropriate. |
| |
| - Issue #17828: The interpreter now attempts to chain errors that occur in |
| codec processing with a replacement exception of the same type that |
| includes the codec name in the error message. It ensures it only does this |
| when the creation of the replacement exception won't lose any information. |
| |
| - Issue #19466: Clear the frames of daemon threads earlier during the |
| Python shutdown to call objects destructors. So "unclosed file" resource |
| warnings are now corretly emitted for daemon threads. |
| |
| - Issue #19514: Deduplicate some _Py_IDENTIFIER declarations. |
| Patch by Andrei Dorian Duma. |
| |
| - Issue #17936: Fix O(n**2) behaviour when adding or removing many subclasses |
| of a given type. |
| |
| - Issue #19428: zipimport now handles errors when reading truncated or invalid |
| ZIP archive. |
| |
| - Issue #18408: Add a new PyFrame_FastToLocalsWithError() function to handle |
| exceptions when merging fast locals into f_locals of a frame. |
| PyEval_GetLocals() now raises an exception and return NULL on failure. |
| |
| - Issue #19369: Optimized the usage of __length_hint__(). |
| |
| - Issue #18603: Ensure that PyOS_mystricmp and PyOS_mystrnicmp are in the |
| Python executable and not removed by the linker's optimizer. |
| |
| - Issue #19306: Add extra hints to the faulthandler module's stack |
| dumps that these are "upside down". |
| |
| Library |
| ------- |
| |

| written in C. |
| |
| - Issue #13477: Added command line interface to the tarfile module. |
| Original patch by Berker Peksag. |
| |
| - Issue #19674: inspect.signature() now produces a correct signature |
| for some builtins. |
| |
| - Issue #19722: Added opcode.stack_effect(), which |
| computes the stack effect of bytecode instructions. |
| |
| - Issue #19735: Implement private function ssl._create_stdlib_context() to |
| create SSLContext objects in Python's stdlib module. It provides a single |
| configuration point and makes use of SSLContext.load_default_certs(). |
| |
| - Issue #16203: Add re.fullmatch() function and regex.fullmatch() method, |
| which anchor the pattern at both ends of the string to match. |
| Original patch by Matthew Barnett. |
| |
| - Issue #13592: Improved the repr for regular expression pattern objects. |
| Based on patch by Hugo Lopes Tavares. |
| |
| - Issue #19641: Added the audioop.byteswap() function to convert big-endian |
| samples to little-endian and vice versa. |
| |
| - Issue #15204: Deprecated the 'U' mode in file-like objects. |

| |
| - Issue #19689: Add ssl.create_default_context() factory function. It creates |
| a new SSLContext object with secure default settings. |
| |
| - Issue #19727: os.utime(..., None) is now potentially more precise |
| under Windows. |
| |
| - Issue #17201: ZIP64 extensions now are enabled by default. Patch by |
| William Mallard. |
| |
| - Issue #19292: Add SSLContext.load_default_certs() to load default root CA |
| certificates from default stores or system stores. By default the method |
| loads CA certs for authentication of server certs. |
| |
| - Issue #19673: Add pathlib to the stdlib as a provisional module (PEP 428). |
| |
| - Issue #16596: pdb in a generator now properly skips over yield and |
| yield from rather than stepping out of the generator into its |
| caller. (This is essential for stepping through asyncio coroutines.) |
| |
| - Issue #17916: Added dis.Bytecode.from_traceback() and |
| dis.Bytecode.current_offset to easily display "current instruction" |
| markers in the new disassembly API (Patch by Claudiu Popa). |
| |
| - Issue #19552: venv now supports bootstrapping pip into virtual environments |
| |
| - Issue #17134: Finalize interface to Windows' certificate store. Cert and |
| CRL enumeration are now two functions. enum_certificates() also returns |
| purpose flags as set of OIDs. |
| |
| - Issue #19555: Restore sysconfig.get_config_var('SO'), (and the distutils |
| equivalent) with a DeprecationWarning pointing people at $EXT_SUFFIX. |
| |
| - Issue #8813: Add SSLContext.verify_flags to change the verification flags |
| of the context in order to enable certification revocation list (CRL) |
| checks or strict X509 rules. |
| |
| - Issue #18294: Fix the zlib module to make it 64-bit safe. |

| |
| - Issue #19633: Fixed writing not compressed 16- and 32-bit wave files on |
| big-endian platforms. |
| |
| - Issue #18379: SSLSocket.getpeercert() returns CA issuer AIA fields, OCSP |
| and CRL distribution points. |
| |
| - Issue #18138: Implement cadata argument of SSLContext.load_verify_location() |
| to load CA certificates and CRL from memory. It supports PEM and DER |
| encoded strings. |
| |
| - Issue #18775: Add name and block_size attribute to HMAC object. They now |
| provide the same API elements as non-keyed cryptographic hash functions. |
| |
| - Issue #17276: MD5 as default digestmod for HMAC is deprecated. The HMAC |
| module supports digestmod names, e.g. hmac.HMAC('sha1'). |
| |
| - Issue #19449: in csv's writerow, handle non-string keys when generating the |
| error message that certain keys are not in the 'fieldnames' list. |
| |
| - Issue #13633: Added a new convert_charrefs keyword arg to HTMLParser that, |
| when True, automatically converts all character references. |

| |
| - Issue #19634: time.strftime("%y") now raises a ValueError on AIX when given a |
| year before 1900. |
| |
| - Fix test.support.bind_port() to not cause an error when Python was compiled |
| on a system with SO_REUSEPORT defined in the headers but run on a system |
| with an OS kernel that does not support that reasonably new socket option. |
| |
| - Fix compilation error under gcc of the ctypes module bundled libffi for arm. |
| |
| - Issue #19448: Add private API to SSL module to lookup ASN.1 objects by OID, |
| NID, short name and long name. |
| |
| - Issue #19282: dbm.open now supports the context management protocol. (Inital |
| patch by Claudiu Popa) |

| sunau, and wave modules. |
| |
| - Issue #5202: Added support for unseekable files in the wave module. |
| |

| a year before 1900 and a format of %y. |
| |
| - Issue #19406: implementation of the ensurepip module (part of PEP 453). |
| Patch by Donald Stufft and Nick Coghlan. |
| |
| - Issue #19544 and Issue #6286: Restore use of urllib over http allowing use |
| of http_proxy for Distutils upload command, a feature accidentally lost |
| in the rollback of distutils2. |
| |
| - Issue #19544 and Issue #7457: Restore the read_pkg_file method to |
| distutils.dist.DistributionMetadata accidentally removed in the undo of |
| distutils2. |
| |
| - Issue #16685: Added support for any bytes-like objects in the audioop module. |
| Removed support for strings. |
| |
| - Issue #7171: Add Windows implementation of ``inet_ntop`` and ``inet_pton`` |
| to socket module. Patch by Atsuo Ishimoto. |

| printing output. |
| |
| - Issue #19378: the "line_offset" parameter in the new "dis.get_instructions" |
| API has been renamed to "first_line" (and the default value and usage |
| changed accordingly). This should reduce confusion with the more common use |
| of "offset" in the dis docs to refer to bytecode offsets. |
| |
| - Issue #18678: Corrected spwd struct member names in spwd module: |
| sp_nam->sp_namp, and sp_pwd->sp_pwdp. The old names are kept as extra |
| structseq members, for backward compatibility. |

| |
| Release date: 2013-10-20 |
| |

| global qualname. |
| |
| - Issue #19279: UTF-7 decoder no longer produces illegal strings. |
| |
| - Issue #16612: Add "Argument Clinic", a compile-time preprocessor for |
| C files to generate argument parsing code. (See PEP 436.) |
| |
| - Issue #18810: Shift stat calls in importlib.machinery.FileFinder such that |
| the code is optimistic that if something exists in a directory named exactly |
| like the possible package being searched for that it's in actuality a |
| directory. |
| |
| - Issue #18416: importlib.machinery.PathFinder now treats '' as the cwd and |
| importlib.machinery.FileFinder no longer special-cases '' to '.'. This leads |
| to modules imported from cwd to now possess an absolute file path for |
| __file__ (this does not affect modules specified by path on the CLI but it |
| does affect -m/runpy). It also allows FileFinder to be more consistent by not |
| having an edge case. |
| |
| - Issue #4555: All exported C symbols are now prefixed with either |
| "Py" or "_Py". |
| |
| - Issue #19219: Speed up marshal.loads(), and make pyc files slightly |
| (5% to 10%) smaller. |

| PyMem_Realloc(). |
| |

| - Fix a reference count leak in _sre. |
| |
| - Issue #19262: Initial check in of the 'asyncio' package (a.k.a. Tulip, |
| a.k.a. PEP 3156). There are no docs yet, and the PEP is slightly |
| out of date with the code. This module will have *provisional* status |
| in Python 3.4. |
| |
| - Issue #19276: Fixed the wave module on 64-bit big-endian platforms. |
| |
| - Issue #19266: Rename the new-in-3.4 ``contextlib.ignore`` context manager |
| to ``contextlib.suppress`` in order to be more consistent with existing |
| descriptions of that operation elsewhere in the language and standard |
| library documentation (Patch by Zero Piraeus). |
| |
| - Issue #18891: Completed the new email package (provisional) API additions |

| - Issue #19131: The aifc module now correctly reads and writes sampwidth of |
| compressed streams. |
| |
| - Issue #19209: Remove import of copyreg from the os module to speed up |
| interpreter startup. stat_result and statvfs_result are now hard-coded to |
| reside in the os module. |
| |
| - Issue #19205: Don't import the 're' module in site and sysconfig module to |
| speed up interpreter start. |
| |
| - Issue #9548: Add a minimal "_bootlocale" module that is imported by the |

| |
| - Issue #17839: base64.decodebytes and base64.encodebytes now accept any |

| when necessary. Patch by Oscar Benjamin. |
| |

| 2. ppc arch detection in configure did not work on OS X 10.4 |
| 3. -sysroot and -arch flags were unnecessarily duplicated |
| 4. there was no obvious way to configure an intel-32 only build. |
| |
| - Issue #19019: Change the OS X installer build script to use CFLAGS instead |
| of OPT for special build options. By setting OPT, some compiler-specific |
| options like -fwrapv were overridden and thus not used, which could result |
| in broken interpreters when building with clang. |

| Patch by Claudiu Popa. |
| |
| - Issue #18756: os.urandom() now uses a lazily-opened persistent file |
| descriptor, so as to avoid using many file descriptors when run in |
| parallel from multiple threads. |
| |

| strings for ``rfc822Name`` (email), ``dNSName`` (DNS) and |
| ``uniformResourceIdentifier`` (URI). |
| |

| |
| - Issue #16799: Switched from getopt to argparse style in regrtest's argument |
| parsing. Added more tests for regrtest's argument parsing. |
| |

| shipped in OS X 10.6 and later releases. |
| |
| Tools/Demos |

| |
| - Issue #16290: A float return value from the __complex__ special method is no |
| longer accepted in the complex() constructor. |
| |
| - Issue #16416: On Mac OS X, operating system data are now always |
| encoded/decoded to/from UTF-8/surrogateescape, instead of the locale encoding |
| (which may be ASCII if no locale environment variable is set), to avoid |
| inconsistencies with os.fsencode() and os.fsdecode() functions which are |
| already using UTF-8/surrogateescape. |
| |
| - Issue #16453: Fix equality testing of dead weakref objects. |
| |
