644
Ned Deily657b2de2011-06-28 19:51:30 -0700645- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
646 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
647 interpreter process. This could cause failures in non-Distutils subprocesses
648 and was unreliable since tests or user programs could modify the interpreter
649 environment after Distutils set it. Instead, have Distutils set the the
650 deployment target only in the environment of each build subprocess. It is
651 still possible to globally override the default by setting
652 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
653 greater or equal to the default value, the value with which the interpreter
654 was built.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002152 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002497- Issue #10068: Global objects which have reference cycles with their module's
2498 dict are now cleared again. This causes issue #7140 to appear again.
2499
Victor Stinner257d38f2010-10-09 10:12:11 +00002500- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002501 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002502
Georg Brandl27a28582010-10-10 09:49:21 +00002503- ast.literal_eval() can now handle negative numbers. It is also a little more
2504 liberal in what it accepts without compromising the safety of the evaluation.
2505 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002506
Benjamin Peterson970d1882010-10-02 17:55:47 +00002507- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2508 result metaclasses can now be ABCs (see #9533).
2509
Victor Stinneraef57e32010-10-02 11:50:49 +00002510- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2511
Victor Stinner5593d8a2010-10-02 11:11:27 +00002512- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002513 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2514 32 bits wchar_t (eg. Linux in narrow build).

Brett Cannon5305a992010-09-27 21:08:38 +00002521- Issue #7397: Mention that importlib.import_module() is probably what someone
2522 really wants to be using in __import__'s docstring.
2523
Georg Brandl27a28582010-10-10 09:49:21 +00002524- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2525 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002526
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002527- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002528 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002529
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002530- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2531
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002532- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2533 threads are still running. Instead, reinitialize the GIL on a second call to
2534 Py_Initialize().
2535
Georg Brandl27a28582010-10-10 09:49:21 +00002536- All SyntaxErrors now have a column offset and therefore a caret when the error
2537 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002538
Brett Cannonbc2eff32010-09-19 21:39:02 +00002539- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2540 module that was imported, but instead gets the module from sys.modules.
2541
Nick Coghlan37ee8502010-12-03 14:26:13 +00002542- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002543 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002544
Georg Brandl27a28582010-10-10 09:49:21 +00002545- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2546 with a non-empty format string. This is an effort to future-proof user
2547 code. If a derived class does not currently implement __format__ but later
2548 adds its own __format__, it would most likely break user code that had
2549 supplied a format string. This will be changed to a DeprecationWaring in
2550 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002551
Antoine Pitrou1df15362010-09-13 14:16:46 +00002552- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2553 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2554 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2555
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002556- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2557 functions from the libc caused the methods .upper() and lower() to become
2558 locale aware and created subtly wrong results.
2559
Georg Brandl27a28582010-10-10 09:49:21 +00002560- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2561 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002562
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002563- Issue #4617: Previously it was illegal to delete a name from the local
2564 namespace if it occurs as a free variable in a nested block. This limitation
2565 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2566
Georg Brandl27a28582010-10-10 09:49:21 +00002567- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2568 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2569 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2570 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002571
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002572- Issue #9757: memoryview objects get a release() method to release the
2573 underlying buffer (previously this was only done when deallocating the
2574 memoryview), and gain support for the context management protocol.
2575
Antoine Pitrou079ce542010-09-08 12:37:10 +00002576- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2577 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002593- Issue #4661: email can now parse bytes input and generate either converted

2595
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002596- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2601
Éric Araujo6108bf52010-10-04 23:52:37 +00002602- Issue #9042: Fix interaction of custom translation classes and caching in
2603 gettext.
2604
Éric Araujoef777bd2010-10-05 00:04:20 +00002605- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002606 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002607 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002608 replacement for old handle_accept() and avoids the user to call accept()
2609 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002632- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002633 retry the select() loop instead of bailing out. This is because select() can
2634 incorrectly report a socket as ready for reading (for example, if it received
2635 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002692- Issue #9854: The default read() implementation in io.RawIOBase now handles
2693 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002694
Georg Brandl27a28582010-10-10 09:49:21 +00002695- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2696 supporting the whole socket API (rather than the "raw" _socket.socket
2697 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002698
Georg Brandl27a28582010-10-10 09:49:21 +00002699- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
2700 to match the corresponding socket methods.

Éric Araujod8c73c62011-03-21 03:15:22 +01002702- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
Georg Brandl27a28582010-10-10 09:49:21 +00002703 them handle recursive calls within the same thread.

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002709- Issue #9837: The read() method of ZipExtFile objects (as returned by
2710 ZipFile.open()) could return more bytes than requested.
2711
Georg Brandl27a28582010-10-10 09:49:21 +00002712- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2713 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002714
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002715- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002716 it possible for the user to create self-referencing ordered dictionaries which
2717 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002718 approach of using weakref proxies so that reference cycles never get created
2719 in the first place.
2720
Victor Stinnercb043522010-09-10 23:49:04 +00002721- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2722 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002723 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002724
Georg Brandl27a28582010-10-10 09:49:21 +00002725- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2726 environment variable to set the filesystem encoding at Python startup.
2727 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2728 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002729
Georg Brandl27a28582010-10-10 09:49:21 +00002730- Issue #9410: Various optimizations to the pickle module, leading to speedups
2731 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2732 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002733
Georg Brandl27a28582010-10-10 09:49:21 +00002734- The pprint module now supports printing OrderedDicts in their given order
2735 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002737- Logging: Added QueueHandler class to facilitate logging usage with
2738 multiprocessing.
2739
Georg Brandl27a28582010-10-10 09:49:21 +00002740- Issue #9707: Rewritten reference implementation of threading.local which is
2741 friendlier towards reference cycles. This change is not normally visible
2742 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002743
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002744- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2745 still return the id of the parent process after it has exited. This process
2746 id may even have been reused by another unrelated process.
2747
Georg Brandl27a28582010-10-10 09:49:21 +00002748- Issue #9792: In case of connection failure, socket.create_connection() would
2749 swallow the exception and raise a new one, making it impossible to fetch the
2750 original errno, or to filter timeout errors. Now the original error is
2751 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002753- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2754 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2755 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002756
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002757- Updates to the random module:
2758
Georg Brandl27a28582010-10-10 09:49:21 +00002759 * Document which parts of the module are guaranteed to stay the same across
2760 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002761
Georg Brandl27a28582010-10-10 09:49:21 +00002762 * Update the seed() method to use all of the bits in a string instead of just
2763 the hash value. This makes better use of the seed value and assures the
2764 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002765
Georg Brandl27a28582010-10-10 09:49:21 +00002766 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2767 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2768 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002769
2770 * Improved documentation of arguments to randrange(). Issue #9379.

2776 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2777 given warning type was triggered by the code under test.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002785- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002786 unsupported operation is attempted (for example, writing to a file open only
2787 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002789- hashlib has two new constant attributes: algorithms_guaranteed and
2790 algorithms_avaiable that respectively list the names of hash algorithms
2791 guaranteed to exist in all Python implementations and the names of hash
2792 algorithms available in the current process.
2793
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002794- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002884- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2885 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2886 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00002897- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2898 now removed, since their effect was inexistent in 3.x (the default encoding is
2899 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002900
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002901- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2903
Georg Brandl649971e2010-09-05 17:06:50 +00002904- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2905 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002906

2921 return characters from the full Unicode range, even on narrow unicode builds
2922 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2923 in Python is that unicodedata.numeric() now returns the correct value for
2924 large code points, and repr() may consider more characters as printable.
2925
Victor Stinner6c00c142010-08-17 23:37:11 +00002926- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2927 as a unicode object, instead of a byte string. Function needed to support
2928 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2929 function.
2930
Victor Stinner6961bd62010-08-17 22:26:51 +00002931- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().

Ezio Melotti57221d02010-07-01 07:32:02 +00003304- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003305 start byte and the continuation byte(s) are now considered invalid, instead of
3306 the number of bytes specified by the start byte. E.g.:
3307 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3308 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3309 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3310 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003340- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003341 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003353- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3354 TypeError instead of giving a DeprecationWarning when a float is parsed using
3355 the 'L' code (for long long). (All other integer codes already raise
3356 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003357
Victor Stinner600d3be2010-06-10 12:00:55 +00003358- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3360 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3361
Georg Brandl62069d32010-07-31 08:56:11 +00003362- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3363 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003364
3365- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003366 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003367 like bytearray.
3368
Georg Brandl62069d32010-07-31 08:56:11 +00003369- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003370 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00003377- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3378 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3379 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3380 equal value.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003382- Issue #8748: Fix two issues with comparisons between complex and integer
3383 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003384 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3385 (2) The comparison raised an OverflowError for large integers, leading to
3386 unpredictable exceptions when combining integers and complex objects in sets
3387 or dicts.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003689- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3690 variable argument list. `Py_VA_COPY` is equivalent to C99
3691 `va_copy`, but available on all python platforms.
3692
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003693- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3694 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3695 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003705- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003706 function declaration, which was kept for backwards compatibility reasons, is
3707 now removed (the macro was introduced in 1997!).

3717 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3718 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003719 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003729- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3730 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3731 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3748 gives improved memory leak detection when running under Valgrind, while taking
3749 advantage of pymalloc at other times.

3825 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003826 applications that use a lot of regular expressions and limits the impact of
3827 the performance hit anytime the cache is exceeded.

3840 module is renamed to `_datetime` and if available, overrides all classes
3841 defined in datetime with fast C impementation. Python implementation is based
3842 on the original python prototype for the datetime module by Tim Peters with
3843 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004081- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4082 operation raises multiple signals and more than one of those signals is
4083 trapped, the specification determines the order in which the signals should be
4084 handled. In many cases this order wasn't being followed, leading to the wrong
4085 Python exception being raised.

4242 return a result based on the numeric values of the operands; previously they

4306 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004308- subprocess.Popen now has restore_signals and start_new_session features. The
4309 default of restore_signals=True is a new behavior compared to earlier Python
4310 versions. This means that signals such as SIGPIPE are not ignored by default
4311 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004804- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004805 compared to other unix systems. In particular, os.getgroups() does not reflect
4806 any changes made using os.setgroups() but basicly always returns the same
4807 information as the id command. os.getgroups() can now return more than 16
4808 groups on MacOSX.

4834 Prior to this change, timezone adjustment in utctimetuple() could produce
4835 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00004838- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4839 directive. When the ``%z`` directive is present in the format string, an
4840 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4841 ``datetime.timezone`` instance constructed from the parsed offset. If both
4842 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4843 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004845- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004846 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4847 ``datetime.timezone``, return fixed name and UTC offset from their
4848 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4849 returns ``None``. A class attribute, ``utc`` contains an instance
4850 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004866- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4867 with an improved 'binary-split' algorithm that uses fewer multiplications and
4868 allows many of the multiplications to be performed using plain C integer
4869 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4870 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004875- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4876 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004877 the result is now always correctly rounded, and is equivalent to ``td /
4878 timedelta(seconds=1)``.

4887 integer format code, struct.pack first attempts to convert the non-integer
4888 using its __index__ method. If that method is non-existent or raises
4889 TypeError it goes on to try the __int__ method, as described below.

5271
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005272- Issue #6137: The pickle module now translates module names when loading
5273 or dumping pickles with a 2.x-compatible protocol, in order to make data
5274 sharing and migration easier. This behaviour can be disabled using the
5275 new `fix_imports` optional argument.

5328
Eric Smith41669ca2009-05-23 14:23:22 +00005329- Issue #6089: Fixed str.format with certain invalid field specifiers
5330 that would raise SystemError.
5331
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005332- Issue #5982: staticmethod and classmethod now expose the wrapped
5333 function with __func__.
5334
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005335- Added support for multiple context managers in the same with-statement.
5336 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005338- Issue #5829: complex("1e500") no longer raises OverflowError. This
5339 makes it consistent with float("1e500") and interpretation of real
5340 and imaginary literals.
5341
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005342- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

5345
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005346- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5347 (1) inf and nan strings with trailing whitespace were incorrectly
5348 rejected; (2) parsing of strings representing infinities and nans
5349 was locale aware; and (3) the interpretation of fromhex('-nan')
5350 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00005355- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
5356
R. David Murrayfb123912009-05-28 18:19:00 +00005357- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
5358
R. David Murray1f1b9d32009-05-27 20:56:59 +00005359- Issue #6121: pydoc now ignores leading and trailing spaces in the

5361
Georg Brandlfaf41492009-05-26 18:31:11 +00005362- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
5363 arguments for strings with a space in them.
5364
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00005365- collections.namedtuple() was not working with the following field
5366 names: cls, self, tuple, itemgetter, and property.
5367
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005368- In unittest, using a skipping decorator on a class is now equivalent to
5369 skipping every test on the class. The ClassTestSuite class has been removed.
5370
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005371- Issue #6050: Don't fail extracting a directory from a zipfile if
5372 the directory already exists.
5373
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005374- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5375 than an int, which makes some operations possible under 64-bit Linux (e.g.
5376 DN_MULTISHOT with F_NOTIFY).
5377
Antoine Pitrou716c4442009-05-23 19:04:03 +00005378- Issue #5761: Add the name of the underlying file to the repr() of various
5379 IO objects.
5380
R. David Murraycaa27b72009-05-23 18:49:56 +00005381- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5382 by Musashi Tamura, tests by Marcin Bachry.
5383
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005384- Issue #1983: Fix functions taking or returning a process identifier to use
5385 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5386 a process identifier type wider than the standard C integer type.
5387
R. David Murray87e20742009-05-23 01:30:26 +00005388- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5399
Antoine Pitroue4501852009-05-14 18:55:55 +00005400- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5401 library. This means, for example, that opening an UTF-16 text file in
5402 append mode doesn't add a BOM at the end of the file if the file isn't
5403 empty.
5404
R. David Murray74b89242009-05-13 17:33:03 +00005405- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5406 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5407 corrects a pydoc regression.
5408
Georg Brandl5f90d792010-08-01 22:31:05 +00005409- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005410 now it does. This also means getfp method now returns the real fp.

5413------------
5414
5415- Issue #6047: fullinstall has been removed because Python 3's executable will
5416 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00005417
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00005418- Lib/smtpd.py is no longer installed as a script.

Georg Brandl5f90d792010-08-01 22:31:05 +00005442- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005443 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005448What's New in Python 3.1 beta 1?
5449================================
5450
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005451*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005452
5453Core and Builtins
5454-----------------
5455
Mark Dickinson865e01a2009-05-07 16:37:01 +00005456- Issue #5914: Add new C API function PyOS_string_to_double, and
5457 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5458
Eric Smith741191f2009-05-06 13:08:15 +00005459- Issue #3382: float.__format__, complex.__format__, and %-formatting
5460 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5461 affects nan -> NAN and inf -> INF.
5462
Mark Hammond5a607a32009-05-06 08:04:54 +00005463- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5464 in all operations, including splitdrive, split, etc. splitunc() now issues
5465 a PendingDeprecation warning.
5466
Eric Smith63376222009-05-05 14:04:18 +00005467- Issue #5920: For float.__format__, change the behavior with the
5468 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5469 to be like 'g' but with at least one decimal point and with a
5470 default precision of 12. Previously, the behavior the same but with
5471 a default precision of 6. This more closely matches str(), and
5472 reduces surprises when adding alignment flags to the empty
5473 presentation type. This also affects the new complex.__format__ in
5474 the same way.
5475
Martin v. Löwis011e8422009-05-05 04:43:17 +00005476- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5477
R. David Murrayb18500d2009-05-04 22:59:07 +00005478- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5479 shadowed by classtype's, even if it was None. property now
5480 inserts the __doc__ into the subclass instance __dict__.
5481
Antoine Pitrou244651a2009-05-04 18:56:13 +00005482- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5483 sequences. Patch by Nick Barnes and Victor Stinner.
5484
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005485- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005486
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005487- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5488 received a new method, detach(). detach() disconnects the underlying stream
5489 from the buffer or text IO and returns it.
5490
Mark Dickinson33841c32009-05-01 15:37:04 +00005491- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5492 floats with absolute value over 1e50. Also remove length
5493 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5494 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005495
Eric Smith741191f2009-05-06 13:08:15 +00005496- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005497 format(complex(1, 2./3), '.5') now produces a sensible result.
5498
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005499- Issue #5864: Fix empty format code formatting for floats so that it
5500 never gives more than the requested number of significant digits.
5501
Eric Smith6dc46f52009-04-27 20:39:49 +00005502- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5503 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5504
Eric Smithcc32a112009-04-26 21:35:14 +00005505- Issue #5835: Deprecate PyOS_ascii_formatd.
5506
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005507- Issue #4971: Fix titlecase for characters that are their own
5508 titlecase, but not their own uppercase.
5509
Benjamin Peterson193152c2009-04-25 01:08:45 +00005510- Issue #5283: Setting __class__ in __del__ caused a segfault.
5511
Mark Dickinsonad476da2009-04-23 19:14:16 +00005512- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5513 z involves nans, infs or negative zeros.
5514
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005515- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005516
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005517- Issue #1869 (and many duplicates): make round(x, n) correctly
5518 rounded for a float x, by using the decimal <-> binary conversions
5519 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5520 consistently agrees with format(x, '.2f').
5521
Benjamin Petersonae937c02009-04-18 20:54:08 +00005522- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5523 some builtin types.
5524
Eric Smith0923d1d2009-04-16 20:16:10 +00005525- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5526
Eric Smith35e84722009-04-16 20:21:28 +00005527- Issue #5515: str.format() type 'n' combined with commas and leading
5528 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005529
5530- Implement PEP 378, Format Specifier for Thousands Separator, for
5531 floats.
5532
Mark Dickinson3370cce2009-04-17 22:40:53 +00005533- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005534 1e11, not 1e12. This avoids printing 13 significant digits in
5535 situations where only 12 of them are correct. Example problem
5536 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5537 long time.)
5538
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005539- Issue #1580: On most platforms, use a 'short' float repr: for a
5540 finite float x, repr(x) now outputs a string based on the shortest
5541 sequence of decimal digits that rounds to x. Previous behaviour was
5542 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005543 Another minor difference is that the new repr switches to
5544 exponential notation at 1e16 instead of the previous 1e17; this
5545 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005546
5547 There's a new sys attribute sys.float_repr_style, which takes
5548 the value 'short' to indicate that we're using short float repr,
5549 and 'legacy' if the short float repr isn't available for one
5550 reason or another.

5552 The float repr change involves incorporating David Gay's 'perfect
5553 rounding' code into the Python core (it's in Python/dtoa.c). As a
5554 secondary consequence, all string-to-float and float-to-string
5555 conversions (including all float formatting operations) will be
5556 correctly rounded on these platforms.

5562
Georg Brandlabc38772009-04-12 15:51:51 +00005563- The string.maketrans() function is deprecated; there is a new static method
5564 maketrans() on the bytes and bytearray classes. This removes confusion about
5565 the types string.maketrans() is supposed to work with, and mirrors the
5566 methods available on the str class.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005860- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5861 it now forces its argument to double before testing for infinity.
5862
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005863- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005873- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005874 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00005876- Issue #4707: round(x, n) now returns an integer if x is an integer.
5877 Previously it returned a float.
5878
Antoine Pitroub52ec782009-01-25 16:34:23 +00005879- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5880 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5881 evaluation loop is compiled with a new dispatch mechanism which gives
5882 speedups of up to 20%, depending on the system, on various benchmarks.

Mark Dickinson8055afd2009-01-17 10:04:45 +00005894- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005895 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005896
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005897- Issue #4935: The overflow checking code in the expandtabs() method common
5898 to str, bytes and bytearray could be optimized away by the compiler, letting
5899 the interpreter segfault instead of raising an error.
5900
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005901- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5902 __next__ method.
5903
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005904- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

5911
Antoine Pitrouab868312009-01-10 15:40:25 +00005912- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5913 common cases are optimized thanks to a dedicated fast path and a moderate
5914 amount of loop unrolling.
5915
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005916- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5917 collecting the oldest generation) so that allocating lots of objects without
5918 destroying them does not show quadratic performance. Based on a proposal by
5919 Martin von Löwis at
5920 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5921
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005922- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005923 having been closed (for instance, a read() call could return some
5924 previously buffered data). Patch by Dmitry Vasiliev.
5925
Antoine Pitrou05608432009-01-09 18:53:14 +00005926- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5927 flag to work properly. Furthermore, when specifying -u, the text stdout
5928 and stderr streams have line-by-line buffering enabled (the default being
5929 to buffer arbitrary chunks of data).
5930
Raymond Hettinger35631532009-01-09 03:58:09 +00005931- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5932 instead of ints (reducing its size from 4 to 8 times thereby reducing
5933 Python's overall memory).
5934
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005935- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5936 an existing .py counterpart, override the co_filename attributes of all
5937 code objects if the original filename is obsolete (which can happen if the
5938 file has been renamed, moved, or if it is accessed through different paths).
5939 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5940
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005941- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5942 one byte. Also fixes the meaning of len() so that it returns the number of
5943 items, rather than the size in bytes.
5944
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005945- Issue #4075: Use OutputDebugStringW in Py_FatalError.

5949
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005950- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5958
Georg Brandlccc47b62008-12-28 11:44:14 +00005959- Issue #4759: None is now allowed as the first argument of

5961
Skip Montanaro80072cb2008-12-23 03:51:14 +00005962- Added test case to ensure attempts to read from a file opened for writing
5963 fail.

5978 failures on OS X.
5979
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005980- Issue #4597: Fixed several opcodes that weren't always propagating
5981 exceptions.
5982
5983- Issue #4589: Fixed exception handling when the __exit__ function of a

5985
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005986- Issue #4445: Replace "sizeof(PyBytesObject)" with
5987 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5988 bytes instances. On a typical machine this saves 3 bytes of memory
5989 (on average) per allocation of a bytes instance.
5990
Christian Heimesa872de52008-12-05 08:26:55 +00005991- Issue #4533: File read operation was dreadfully slow due to a slowly
5992 growing read buffer. Fixed by using the same growth rate algorithm as
5993 Python 2.x.
5994
Antoine Pitrou5504e892008-12-06 21:27:53 +00005995- Issue #4509: Various issues surrounding resize of bytearray objects to

5997
Georg Brandlf9734072008-12-07 15:30:06 +00005998- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5999 method on file objects with closefd=False. The file descriptor is still
6000 kept open but the file object behaves like a closed file. The ``FileIO``
6001 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00006010- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6011 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6012 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6013 of using the replace error handler in PyUnicode_DecodeUTF8().
