Ned Deily657b2de2011-06-28 19:51:30 -0700671- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
672 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
673 interpreter process. This could cause failures in non-Distutils subprocesses
674 and was unreliable since tests or user programs could modify the interpreter
675 environment after Distutils set it. Instead, have Distutils set the the
676 deployment target only in the environment of each build subprocess. It is
677 still possible to globally override the default by setting
678 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
679 greater or equal to the default value, the value with which the interpreter
680 was built.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001520- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001521 continuation line in the formatted value has no leading white space and looks
1522 like a header. Since Generator uses Header to format all headers, this check
1523 is made for all headers in any serialized message at serialization time. This
1524 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00001534 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001535
Éric Araujof0ab5d62011-05-29 03:43:59 +02001536- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001537 rfc2047-encoding header values with embedded newlines, leaving them without
1538 folding whitespace. It now uses the continuation_ws, as it does for
1539 continuation lines that it creates itself.

1542 time.asctime(), time.ctime() and time.strftime() functions will now format

1544 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1545 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1546 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002523- Issue #10068: Global objects which have reference cycles with their module's
2524 dict are now cleared again. This causes issue #7140 to appear again.
2525
Victor Stinner257d38f2010-10-09 10:12:11 +00002526- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002527 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002528
Georg Brandl27a28582010-10-10 09:49:21 +00002529- ast.literal_eval() can now handle negative numbers. It is also a little more
2530 liberal in what it accepts without compromising the safety of the evaluation.
2531 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002532
Benjamin Peterson970d1882010-10-02 17:55:47 +00002533- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2534 result metaclasses can now be ABCs (see #9533).
2535
Victor Stinneraef57e32010-10-02 11:50:49 +00002536- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2537
Victor Stinner5593d8a2010-10-02 11:11:27 +00002538- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002539 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2540 32 bits wchar_t (eg. Linux in narrow build).

2549
Georg Brandl27a28582010-10-10 09:49:21 +00002550- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2551 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002553- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002554 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002556- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2557
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002558- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2559 threads are still running. Instead, reinitialize the GIL on a second call to
2560 Py_Initialize().
2561
Georg Brandl27a28582010-10-10 09:49:21 +00002562- All SyntaxErrors now have a column offset and therefore a caret when the error
2563 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002564
Brett Cannonbc2eff32010-09-19 21:39:02 +00002565- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2566 module that was imported, but instead gets the module from sys.modules.
2567
Nick Coghlan37ee8502010-12-03 14:26:13 +00002568- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002569 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002570
Georg Brandl27a28582010-10-10 09:49:21 +00002571- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2572 with a non-empty format string. This is an effort to future-proof user
2573 code. If a derived class does not currently implement __format__ but later
2574 adds its own __format__, it would most likely break user code that had
2575 supplied a format string. This will be changed to a DeprecationWaring in
2576 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002577
Antoine Pitrou1df15362010-09-13 14:16:46 +00002578- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2579 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2580 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2581
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002582- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2583 functions from the libc caused the methods .upper() and lower() to become
2584 locale aware and created subtly wrong results.
2585
Georg Brandl27a28582010-10-10 09:49:21 +00002586- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2587 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002588
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002589- Issue #4617: Previously it was illegal to delete a name from the local
2590 namespace if it occurs as a free variable in a nested block. This limitation
2591 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2592
Georg Brandl27a28582010-10-10 09:49:21 +00002593- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2594 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2595 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2596 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002597
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002598- Issue #9757: memoryview objects get a release() method to release the
2599 underlying buffer (previously this was only done when deallocating the
2600 memoryview), and gain support for the context management protocol.
2601
Antoine Pitrou079ce542010-09-08 12:37:10 +00002602- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2603 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002619- Issue #4661: email can now parse bytes input and generate either converted

2621
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002622- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2627
Éric Araujo6108bf52010-10-04 23:52:37 +00002628- Issue #9042: Fix interaction of custom translation classes and caching in
2629 gettext.
2630
Éric Araujoef777bd2010-10-05 00:04:20 +00002631- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002632 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002633 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002634 replacement for old handle_accept() and avoids the user to call accept()
2635 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002637- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002658- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002659 retry the select() loop instead of bailing out. This is because select() can
2660 incorrectly report a socket as ready for reading (for example, if it received
2661 some data with an invalid checksum).

Antoine Pitrou98b46702010-09-18 22:59:00 +00002707- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002708 non-blocking mode: they return None when an operation would block (instead of
2709 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002710
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002711- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Georg Brandl27a28582010-10-10 09:49:21 +00002721- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2722 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002741- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002742 it possible for the user to create self-referencing ordered dictionaries which
2743 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002744 approach of using weakref proxies so that reference cycles never get created
2745 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002750
Georg Brandl27a28582010-10-10 09:49:21 +00002751- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2752 environment variable to set the filesystem encoding at Python startup.
2753 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2754 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002755
Georg Brandl27a28582010-10-10 09:49:21 +00002756- Issue #9410: Various optimizations to the pickle module, leading to speedups

2764 multiprocessing.
2765
Georg Brandl27a28582010-10-10 09:49:21 +00002766- Issue #9707: Rewritten reference implementation of threading.local which is
2767 friendlier towards reference cycles. This change is not normally visible
2768 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002769
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002770- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2771 still return the id of the parent process after it has exited. This process
2772 id may even have been reused by another unrelated process.
2773
Georg Brandl27a28582010-10-10 09:49:21 +00002774- Issue #9792: In case of connection failure, socket.create_connection() would
2775 swallow the exception and raise a new one, making it impossible to fetch the
2776 original errno, or to filter timeout errors. Now the original error is
2777 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002779- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2780 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2781 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002782
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002783- Updates to the random module:
2784
Georg Brandl27a28582010-10-10 09:49:21 +00002785 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002788 * Update the seed() method to use all of the bits in a string instead of just
2789 the hash value. This makes better use of the seed value and assures the
2790 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002792 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2793 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2794 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002795
2796 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002815- hashlib has two new constant attributes: algorithms_guaranteed and
2816 algorithms_avaiable that respectively list the names of hash algorithms
2817 guaranteed to exist in all Python implementations and the names of hash
2818 algorithms available in the current process.

Ezio Melotti57221d02010-07-01 07:32:02 +00003330- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003331 start byte and the continuation byte(s) are now considered invalid, instead of
3332 the number of bytes specified by the start byte. E.g.:
3333 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3334 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3335 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3336 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003366- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003367 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003379- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3380 TypeError instead of giving a DeprecationWarning when a float is parsed using
3381 the 'L' code (for long long). (All other integer codes already raise
3382 TypeError in this case.)

3386 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3387
Georg Brandl62069d32010-07-31 08:56:11 +00003388- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Georg Brandl62069d32010-07-31 08:56:11 +00003392 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003393 like bytearray.
3394
Georg Brandl62069d32010-07-31 08:56:11 +00003395- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

3409 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003410 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3411 (2) The comparison raised an OverflowError for large integers, leading to
3412 unpredictable exceptions when combining integers and complex objects in sets
3413 or dicts.

3436
Victor Stinner0964ee12010-04-30 16:48:45 +00003437- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

Georg Brandl62069d32010-07-31 08:56:11 +00003543 where the right hand operand is a set of constants, by turning the set into a
3544 frozenset and pre-building it as a constant. The comparison operation is made
3545 against the constant instead of building a new set each time it is executed (a
3546 similar optimization already existed which turned a list of constants into a
3547 pre-built tuple). Patch and additional tests by Dave Malcolm.

3714
Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003715- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3716 variable argument list. `Py_VA_COPY` is equivalent to C99
3717 `va_copy`, but available on all python platforms.
3718
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003719- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3720 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3721 "step = -step" when reversing a slice.
3722
Georg Brandl62069d32010-07-31 08:56:11 +00003723- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

3729 strings in an efficient manner.
3730
Antoine Pitrou8689a102010-04-01 16:53:15 +00003731- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003732 function declaration, which was kept for backwards compatibility reasons, is
3733 now removed (the macro was introduced in 1997!).
Antoine Pitrou8689a102010-04-01 16:53:15 +00003734
Georg Brandl62069d32010-07-31 08:56:11 +00003735- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to

Georg Brandl62069d32010-07-31 08:56:11 +00003742 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
3743 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3744 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003745 to match the behaviour of the other integer format codes.
3746
Georg Brandl62069d32010-07-31 08:56:11 +00003747- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00003755- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3756 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3757 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00003758

3770 ``const char *`` as the string is stored beyond the call.
3771
Georg Brandl62069d32010-07-31 08:56:11 +00003772- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3773 allocator will be automatically disabled when running under Valgrind. This
3774 gives improved memory leak detection when running under Valgrind, while taking
3775 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003850 simply clearing the entire cache on overflow to forgetting the least recently
3851 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003852 applications that use a lot of regular expressions and limits the impact of
3853 the performance hit anytime the cache is exceeded.

3866 module is renamed to `_datetime` and if available, overrides all classes
3867 defined in datetime with fast C impementation. Python implementation is based
3868 on the original python prototype for the datetime module by Tim Peters with
3869 minor modifications by the PyPy project. The test suite now tests `datetime`
3870 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004107- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4108 operation raises multiple signals and more than one of those signals is
4109 trapped, the specification determines the order in which the signals should be
4110 handled. In many cases this order wasn't being followed, leading to the wrong
4111 Python exception being raised.

4151 socket wasn't retained (instead, a socket with a positive timeout would be
4152 turned into a non-blocking SSL socket).

Georg Brandl62069d32010-07-31 08:56:11 +00004267- Issue #2531: Comparison operations between floats and Decimal instances now
4268 return a result based on the numeric values of the operands; previously they
4269 returned an arbitrary result based on the relative ordering of id(float) and
4270 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4271 comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004276 argument `-` which tells it to read files to compile from stdin. Each line is

4286 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4287 <=> complex, and complex <=> complex comparisons.

4331 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4332 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004334- subprocess.Popen now has restore_signals and start_new_session features. The
4335 default of restore_signals=True is a new behavior compared to earlier Python
4336 versions. This means that signals such as SIGPIPE are not ignored by default
4337 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004830- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004831 compared to other unix systems. In particular, os.getgroups() does not reflect
4832 any changes made using os.setgroups() but basicly always returns the same
4833 information as the id command. os.getgroups() can now return more than 16
4834 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004859- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4860 Prior to this change, timezone adjustment in utctimetuple() could produce
4861 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4862 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004864- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4865 directive. When the ``%z`` directive is present in the format string, an
4866 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4867 ``datetime.timezone`` instance constructed from the parsed offset. If both
4868 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4869 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004870
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004871- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004872 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4873 ``datetime.timezone``, return fixed name and UTC offset from their
4874 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4875 returns ``None``. A class attribute, ``utc`` contains an instance
4876 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004892- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4893 with an improved 'binary-split' algorithm that uses fewer multiplications and
4894 allows many of the multiplications to be performed using plain C integer
4895 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4896 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004901- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4902 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004903 the result is now always correctly rounded, and is equivalent to ``td /
4904 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00004912- Issue #8300: When passing a non-integer argument to struct.pack with any
4913 integer format code, struct.pack first attempts to convert the non-integer
4914 using its __index__ method. If that method is non-existent or raises
4915 TypeError it goes on to try the __int__ method, as described below.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005364- Issue #5829: complex("1e500") no longer raises OverflowError. This
5365 makes it consistent with float("1e500") and interpretation of real
5366 and imaginary literals.
5367
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005368- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

5373 (1) inf and nan strings with trailing whitespace were incorrectly
5374 rejected; (2) parsing of strings representing infinities and nans
5375 was locale aware; and (3) the interpretation of fromhex('-nan')

5393
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005394- In unittest, using a skipping decorator on a class is now equivalent to

5396
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005397- Issue #6050: Don't fail extracting a directory from a zipfile if

5399
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005400- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5401 than an int, which makes some operations possible under 64-bit Linux (e.g.
5402 DN_MULTISHOT with F_NOTIFY).
5403
Antoine Pitrou716c4442009-05-23 19:04:03 +00005404- Issue #5761: Add the name of the underlying file to the repr() of various

5425
Antoine Pitroue4501852009-05-14 18:55:55 +00005426- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5427 library. This means, for example, that opening an UTF-16 text file in
5428 append mode doesn't add a BOM at the end of the file if the file isn't
5429 empty.

Georg Brandl5f90d792010-08-01 22:31:05 +00005435- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005436 now it does. This also means getfp method now returns the real fp.

5481
Mark Dickinson865e01a2009-05-07 16:37:01 +00005482- Issue #5914: Add new C API function PyOS_string_to_double, and
5483 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5484
Eric Smith741191f2009-05-06 13:08:15 +00005485- Issue #3382: float.__format__, complex.__format__, and %-formatting
5486 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5487 affects nan -> NAN and inf -> INF.
5488
Mark Hammond5a607a32009-05-06 08:04:54 +00005489- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5490 in all operations, including splitdrive, split, etc. splitunc() now issues
5491 a PendingDeprecation warning.
5492
Eric Smith63376222009-05-05 14:04:18 +00005493- Issue #5920: For float.__format__, change the behavior with the
5494 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5495 to be like 'g' but with at least one decimal point and with a
5496 default precision of 12. Previously, the behavior the same but with
5497 a default precision of 6. This more closely matches str(), and
5498 reduces surprises when adding alignment flags to the empty
5499 presentation type. This also affects the new complex.__format__ in
5500 the same way.
5501
Martin v. Löwis011e8422009-05-05 04:43:17 +00005502- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5503
R. David Murrayb18500d2009-05-04 22:59:07 +00005504- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5505 shadowed by classtype's, even if it was None. property now
5506 inserts the __doc__ into the subclass instance __dict__.
5507
Antoine Pitrou244651a2009-05-04 18:56:13 +00005508- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5509 sequences. Patch by Nick Barnes and Victor Stinner.
5510
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005511- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005512
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005513- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5514 received a new method, detach(). detach() disconnects the underlying stream
5515 from the buffer or text IO and returns it.
5516
Mark Dickinson33841c32009-05-01 15:37:04 +00005517- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5518 floats with absolute value over 1e50. Also remove length
5519 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5520 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005521
Eric Smith741191f2009-05-06 13:08:15 +00005522- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005523 format(complex(1, 2./3), '.5') now produces a sensible result.
5524
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005525- Issue #5864: Fix empty format code formatting for floats so that it
5526 never gives more than the requested number of significant digits.
5527
Eric Smith6dc46f52009-04-27 20:39:49 +00005528- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5529 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5530
Eric Smithcc32a112009-04-26 21:35:14 +00005531- Issue #5835: Deprecate PyOS_ascii_formatd.
5532
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005533- Issue #4971: Fix titlecase for characters that are their own
5534 titlecase, but not their own uppercase.
5535
Benjamin Peterson193152c2009-04-25 01:08:45 +00005536- Issue #5283: Setting __class__ in __del__ caused a segfault.
5537
Mark Dickinsonad476da2009-04-23 19:14:16 +00005538- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5539 z involves nans, infs or negative zeros.
5540
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005541- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005542
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005543- Issue #1869 (and many duplicates): make round(x, n) correctly
5544 rounded for a float x, by using the decimal <-> binary conversions
5545 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5546 consistently agrees with format(x, '.2f').
5547
Benjamin Petersonae937c02009-04-18 20:54:08 +00005548- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5549 some builtin types.
5550
Eric Smith0923d1d2009-04-16 20:16:10 +00005551- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5552
Eric Smith35e84722009-04-16 20:21:28 +00005553- Issue #5515: str.format() type 'n' combined with commas and leading
5554 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005555
5556- Implement PEP 378, Format Specifier for Thousands Separator, for
5557 floats.
5558
Mark Dickinson3370cce2009-04-17 22:40:53 +00005559- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005560 1e11, not 1e12. This avoids printing 13 significant digits in
5561 situations where only 12 of them are correct. Example problem
5562 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5563 long time.)

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005565- Issue #1580: On most platforms, use a 'short' float repr: for a
5566 finite float x, repr(x) now outputs a string based on the shortest
5567 sequence of decimal digits that rounds to x. Previous behaviour was
5568 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005569 Another minor difference is that the new repr switches to
5570 exponential notation at 1e16 instead of the previous 1e17; this
5571 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005572
5573 There's a new sys attribute sys.float_repr_style, which takes
5574 the value 'short' to indicate that we're using short float repr,
5575 and 'legacy' if the short float repr isn't available for one
5576 reason or another.
5577
5578 The float repr change involves incorporating David Gay's 'perfect
5579 rounding' code into the Python core (it's in Python/dtoa.c). As a
5580 secondary consequence, all string-to-float and float-to-string
5581 conversions (including all float formatting operations) will be
5582 correctly rounded on these platforms.
5583
Georg Brandl5f90d792010-08-01 22:31:05 +00005584 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005585 this change does not apply.

5588
Georg Brandlabc38772009-04-12 15:51:51 +00005589- The string.maketrans() function is deprecated; there is a new static method
5590 maketrans() on the bytes and bytearray classes. This removes confusion about
5591 the types string.maketrans() is supposed to work with, and mirrors the
5592 methods available on the str class.

5882
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005883- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5884 rotating the object pointer by 4 bits to the right.
5885
Mark Dickinson87ec0852009-02-09 17:15:59 +00005886- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5887 it now forces its argument to double before testing for infinity.
5888
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005889- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

5897 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005898
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005899- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005900 were suppressing all exceptions. These include list() and bytearray().
5901
Mark Dickinson1124e712009-01-28 21:25:58 +00005902- Issue #4707: round(x, n) now returns an integer if x is an integer.

5904
Antoine Pitroub52ec782009-01-25 16:34:23 +00005905- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5906 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5907 evaluation loop is compiled with a new dispatch mechanism which gives
5908 speedups of up to 20%, depending on the system, on various benchmarks.
5909
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005910- Issue #4874: Most builtin decoders now reject unicode input.

5916
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005917- Issue #4838: When a module is deallocated, free the memory backing the
5918 optional module state data.
5919
Mark Dickinson8055afd2009-01-17 10:04:45 +00005920- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005921 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005922
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005923- Issue #4935: The overflow checking code in the expandtabs() method common
5924 to str, bytes and bytearray could be optimized away by the compiler, letting
5925 the interpreter segfault instead of raising an error.
5926
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005927- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5928 __next__ method.
5929
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005930- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5931 function no longer attempt to call the __long__ slot to convert an object
5932 to an integer. Only the __int__ and __trunc__ slots are examined.
5933
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005934- Issue #4893: Use NT threading on CE.
5935

5937
Antoine Pitrouab868312009-01-10 15:40:25 +00005938- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5939 common cases are optimized thanks to a dedicated fast path and a moderate
5940 amount of loop unrolling.
5941
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005942- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5943 collecting the oldest generation) so that allocating lots of objects without
5944 destroying them does not show quadratic performance. Based on a proposal by
5945 Martin von Löwis at
5946 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5947
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005948- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005949 having been closed (for instance, a read() call could return some
5950 previously buffered data). Patch by Dmitry Vasiliev.
5951
Antoine Pitrou05608432009-01-09 18:53:14 +00005952- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5953 flag to work properly. Furthermore, when specifying -u, the text stdout
5954 and stderr streams have line-by-line buffering enabled (the default being
5955 to buffer arbitrary chunks of data).
5956
Raymond Hettinger35631532009-01-09 03:58:09 +00005957- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5958 instead of ints (reducing its size from 4 to 8 times thereby reducing
5959 Python's overall memory).
5960
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005961- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5962 an existing .py counterpart, override the co_filename attributes of all
5963 code objects if the original filename is obsolete (which can happen if the
5964 file has been renamed, moved, or if it is accessed through different paths).
5965 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5966
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005967- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5968 one byte. Also fixes the meaning of len() so that it returns the number of
5969 items, rather than the size in bytes.
5970
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005971- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5972
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005973- Issue #4747: When the terminal does not use utf-8, executing a script with
5974 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5975
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005976- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5977 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005978
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005979- Issue #3680: Reference cycles created through a dict, set or deque iterator
5980 did not get collected.
5981
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005982- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5983 where the tp_hash and tp_dict slots are both NULL.
5984
Georg Brandlccc47b62008-12-28 11:44:14 +00005985- Issue #4759: None is now allowed as the first argument of
5986 bytearray.translate(). It was always allowed for bytes.translate().
5987
Skip Montanaro80072cb2008-12-23 03:51:14 +00005988- Added test case to ensure attempts to read from a file opened for writing
5989 fail.
5990
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005991- Issue #3106: Speedup some comparisons (str/str and int/int).

5995
Antoine Pitrou621601a2008-12-17 23:18:19 +00005996- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5997 print elapsed times, not only when some objects are uncollectable /
5998 unreachable. Original patch by Neil Schemenauer.
5999
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006000- Issue #3439: Add a bit_length method to int.
6001
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006002- Issue #2173: When getting device encoding, check that return value of
6003 nl_langinfo is not the empty string. This was causing silent build
6004 failures on OS X.
6005
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006006- Issue #4597: Fixed several opcodes that weren't always propagating
6007 exceptions.
6008
6009- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006010 context manager returns a value that cannot be converted to a bool.
6011
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006012- Issue #4445: Replace "sizeof(PyBytesObject)" with
6013 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6014 bytes instances. On a typical machine this saves 3 bytes of memory
6015 (on average) per allocation of a bytes instance.
6016
Christian Heimesa872de52008-12-05 08:26:55 +00006017- Issue #4533: File read operation was dreadfully slow due to a slowly
6018 growing read buffer. Fixed by using the same growth rate algorithm as
6019 Python 2.x.
6020
Antoine Pitrou5504e892008-12-06 21:27:53 +00006021- Issue #4509: Various issues surrounding resize of bytearray objects to
6022 which there are buffer exports (e.g. memoryview instances).
6023
Georg Brandlf9734072008-12-07 15:30:06 +00006024- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6025 method on file objects with closefd=False. The file descriptor is still
6026 kept open but the file object behaves like a closed file. The ``FileIO``
6027 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006028
Antoine Pitroubc420402008-12-07 20:14:49 +00006029- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6030 larger than 1.
6031

6035
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006036- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6037 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6038 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6039 of using the replace error handler in PyUnicode_DecodeUTF8().
