1017 32-bit-only installer Pythons on systems with Xcode 4 (currently
1018 OS X 10.8, 10.7, and optionally 10.6).
1019 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1020 * Since Xcode 4 removes ppc support, extension module builds now
1021 check for ppc compiler support and by default remove ppc and
1022 ppc64 archs when they are not available.
1023 * Extension module builds now revert to using system installed
1024 headers and libs (/usr and /System/Library) if the SDK used
1025 to build the interpreter is not installed or has moved.
1026 * Try to avoid building extension modules with deprecated
1027 and problematic Apple llvm-gcc compiler. If original compiler
1028 is not available, use clang instead by default.

1460 Distutils-based packages with C extension modules may fail because
1461 Apple has removed gcc-4.2, the version used to build python.org
1462 64-bit/32-bit Pythons. If the user does not explicitly override
1463 the default C compiler by setting the CC environment variable,
1464 Distutils will now attempt to compile extension modules with clang
1465 if gcc-4.2 is required but not found. Also as a convenience, if
1466 the user does explicitly set CC, substitute its value as the default
1467 compiler in the Distutils LDSHARED configuration variable for OS X.
1468 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1469 SDK, neither of which are available in Xcode 4. This change does not
1470 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001720- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1721 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1722 interpreter process. This could cause failures in non-Distutils subprocesses
1723 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001724 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001725 deployment target only in the environment of each build subprocess. It is
1726 still possible to globally override the default by setting
1727 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1728 greater or equal to the default value, the value with which the interpreter
1729 was built.

1759 the ticker doesn't have to wind down to zero from the old starting point
1760 before the new interval takes effect. And if the user increases the
1761 interval, it makes sure the new limit takes effect right away rather have an

Raymond Hettinger20397532010-09-12 02:11:45 +00002742- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2743 This prevents user-created self-referencing ordered dictionaries from
2744 becoming permanently uncollectable GC garbage. The downside is that
2745 removing __del__ means that the internal doubly-linked list has to wait for
2746 GC collection rather than freeing memory immediately when the refcnt drops
2747 to zero.
2748
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002749- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2752
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002753- Issue #9792: In case of connection failure, socket.create_connection()
2754 would swallow the exception and raise a new one, making it impossible
2755 to fetch the original errno, or to filter timeout errors. Now the
2756 original error is re-raised.
2757
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002758- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2760 be updated back after the system call. Original patch by Brian Brazil.

2777
R. David Murray7c4bf552010-08-25 01:45:57 +00002778- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2779 character years even if the message contains RFC822 two character years.
2780
Daniel Stutzbach91287322010-08-24 21:09:30 +00002781- Issue #8750: Fixed MutableSet's methods to correctly handle

2794
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002795- Issue #9617: Signals received during a low-level write operation aren't
2796 ignored by the buffered IO layer anymore.
2797
Benjamin Peterson52c36052010-08-21 03:03:22 +00002798- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2800
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002801- Issue #9626: the view methods for collections.OrderedDict() were returning

2810 and a BadZipfile error is raised if it doesn't match (as used to be the
2811 case in Python 2.5 and earlier).
2812
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002813- Issue #9550: a BufferedReader could issue an additional read when the
2814 original read request had been satisfied, which could block indefinitely
2815 when the underlying raw IO channel was e.g. a socket. Report and original
2816 patch by Jason V. Miller.
2817
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002818- Issue #9551: Don't raise TypeError when setting the value to None for

2837 This is how it is supposed to work, wget and curl do the same. Previous
2838 behavior was wrong.

2847 does not contain a '-', instead of raising an error.
2848

3595 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00003607- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3608 with a non-empty format string. This is an effort to future-proof user
3609 code. If a derived class does not currently implement __format__ but later
3610 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003611 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003612 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003653- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00003662- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3663 InvalidOperation instead of returning False. (Comparisons involving a quiet
3664 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3665 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003666
Georg Brandlfee0f442010-05-22 21:26:21 +00003667- Issue #2531: Comparison operations between floats and Decimal instances now
3668 return a result based on the numeric values of the operands; previously they
3669 returned an arbitrary result based on the relative ordering of id(float) and
3670 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003671
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003672- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003673 argument `-` which tells it to read files to compile from stdin. Each line is
3674 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003684- Comparisons using one of <, <=, >, >= between a complex instance and a
3685 Fractions instance now raise TypeError instead of returning True/False. This
3686 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3687 <=> complex, and complex <=> complex comparisons.

4050 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4051 returning NULL. The macro now returns a statically allocated empty string
4052 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00004097- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004098 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004104- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004105 file position when calling `truncate()`. It would previously change the file
4106 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004107 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4108
Georg Brandlba83f822010-03-14 09:50:54 +00004109- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4110 class used to represent files stored inside an archive. The new
4111 implementation is significantly faster and can be wrapped in a
4112 ``io.BufferedReader`` object for more speedups. It also solves an issue
4113 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004124- Issue #7748: Since unicode values are supported for some metadata options in
4125 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4126 encoded string for them. This ensures that the upload and register commands
4127 send the correct values to PyPI without any error.

4202-----------------
4203
Georg Brandlba83f822010-03-14 09:50:54 +00004204- The ``__complex__()`` method is now looked up on the class of instances to
4205 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004206
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004207- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4208 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4209
Mark Dickinson1b34d252010-01-01 17:27:30 +00004210- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004211 DeprecationWarning when passed a float argument where an integer was expected.
4212 These functions and methods now raise TypeError instead. The majority of the
4213 effects of this change are in the extension modules, but some core functions
4214 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4215 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00004216
Benjamin Peterson0f02d392009-12-30 19:34:10 +00004217- Issue #7604: Deleting an unset slotted attribute did not raise an

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004225- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4226 used to drop the time part of the result.
4227
Georg Brandlba83f822010-03-14 09:50:54 +00004228- Issue #1811: Improve accuracy and cross-platform consistency for true division
4229 of integers: the result of a/b is now correctly rounded for ints a and b (at
4230 least on IEEE 754 platforms), and in particular does not depend on the
4231 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004232
Georg Brandlba83f822010-03-14 09:50:54 +00004233- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4234 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4235 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004236

Ronald Oussoren92919a62009-12-24 13:30:58 +00004238 executables on OSX.
4239
Georg Brandlba83f822010-03-14 09:50:54 +00004240 These executables now work properly with the arch(1) command: ``arch -ppc
4241 python`` will start a universal binary version of python in PPC mode (unlike
4242 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004243
Georg Brandlba83f822010-03-14 09:50:54 +00004244- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
4245 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +00004256- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
4257 allowing for a maximum number of tasks within the pool to be completed by the
4258 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00004264- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004265 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4266 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00004285- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00004286 Initial patch by Brian Curtin.
4287
Georg Brandlba83f822010-03-14 09:50:54 +00004288- Distutils now correctly identifies the build architecture as "x86_64" when
4289 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00004290

Benjamin Petersonddd392c2009-12-13 19:19:07 +00004301- Issue #7349: Make methods of file objects in the io module accept None as an
4302 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
4303 the same as passing no argument.
4304
Georg Brandlba83f822010-03-14 09:50:54 +00004305- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00004327- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4328 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4329 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4330 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00004398- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4399 decimal string that's guaranteed to round back to x under correct rounding
4400 (with round-half-to-even rounding mode). Previously it gave a string based on
4401 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4402 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4403 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004404
Georg Brandlba83f822010-03-14 09:50:54 +00004405- Issue #7117: On almost all platforms: float-to-string and string-to-float
4406 conversions within Python are now correctly rounded. Places these conversions
4407 occur include: str for floats and complex numbers; the float and complex
4408 constructors; old-style and new-style numeric formatting; serialization and
4409 deserialization of floats and complex numbers using marshal, pickle and json;
4410 parsing of float and imaginary literals in Python code; Decimal-to-float
4411 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004412
Georg Brandlba83f822010-03-14 09:50:54 +00004413 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4414 providing correctly-rounded strtod and dtoa C functions. This code is
4415 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4416 the C compiler. There may be a small number of platforms on which correct
4417 operation of this code cannot be guaranteed, so the code is not used: notably,
4418 this applies to platforms where the C double format is not IEEE 754 binary64,
4419 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4420 and Python's configure script is unable to determine how to change the FPU
4421 precision. On these platforms conversions use the platform strtod and dtoa,
4422 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004423
Georg Brandlba83f822010-03-14 09:50:54 +00004424- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4425 uses the correctly-rounded string <-> float conversions described above (when
4426 available), and so produces correctly rounded results that will display nicely
4427 under the float repr. There are two related small changes: (1) round now
4428 accepts any class with an ``__index__()`` method for its second argument (but
4429 no longer accepts floats for the second argument), and (2) an excessively
4430 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4431 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004649 untrackable objects are not tracked by the garbage collector. This can reduce
4650 the size of collections and therefore the garbage collection overhead on
4651 long-running programs, depending on their particular use of datatypes.

4658 internal representation of integers, for performance reasons. Base 2**30 is
4659 enabled by default on 64-bit machines. Add --enable-big-digits option to
4660 configure, which overrides the default. Add sys.long_info structseq to
4661 provide information about the internal format.

4692
Georg Brandl29c6a282009-04-05 20:23:13 +00004693- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00004694 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00004724- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4725 existing .py counterpart, override the co_filename attributes of all code
4726 objects if the original filename is obsolete (which can happen if the file has

4781
Georg Brandlba83f822010-03-14 09:50:54 +00004782- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4783 file objects with closefd=False. The file descriptor is still kept open but
4784 the file object behaves like a closed file. The ``FileIO`` object also got a
4785 new readonly attribute ``closefd``.

4804
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004805- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004808- On windows, ``os.chdir()`` given unicode was not working if
4809 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4810 this code path is really executed because I cannot move to such directory on
4811 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004813- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4814 element is temporarily replaced with an equivalent frozenset. But the
4815 eventual KeyError would always report the empty ``frozenset()`` as the missing
4816 key. Now it correctly refers to the initial element.

4837 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4838 step. This avoids problems with counting UTF-8 bytes that ignores the effect

4840
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004841- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00006014 - If x is not an int, long or float, then packing x will always result in
6015 struct.error. Previously an x with an __int__ method could be packed by
6016 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6017 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6018 neither __int__ nor __long__, TypeError used to be raised (with a
6019 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6020 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00006021
Georg Brandlba83f822010-03-14 09:50:54 +00006022 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
6023 argument with an __int__ method can be packed, but use of this feature
6024 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006217- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6218 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6219 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6220 ``printf`` function, whereas PyString_FromFormat has an independent
6221 implementation and uses "%zd" on all platforms for size_t values.
6222 This makes a difference on win64, where ``printf`` needs "%Id" to display

Brett Cannon1eaf0742008-09-02 01:25:16 +00006318 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6319 for catch_warnings() also led to an improvement in the raising of a
6320 DeprecationWarning related to warnings.warn_explicit().
6321
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006322- The deprecation warnings for the old camelCase threading API were removed.

6344
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006345- Issue #2975: When compiling several extension modules with Visual Studio 2008
6346 from the same python interpreter, some environment variables would grow
6347 without limit.
6348
Benjamin Peterson37346b22008-08-23 20:27:43 +00006349- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006386What's New in Python 2.6 beta 3?
6387================================
6388
Barry Warsaw07a4a382008-08-21 01:15:08 +00006389*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006390
6391Core and Builtins
6392-----------------
6393
Guido van Rossumf8402962008-08-20 15:01:50 +00006394- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6395 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6396 extensions do not automatically benefit from the class attribute
6397 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6398 to their tp_flags field if they care. This is a backwards
6399 compatibility feature; in 3.0, all types will use the cache by
6400 default.
6401
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006402- Keyword arguments can now follow starred arguments. (``f(a, *args,
6403 keyword=23)`` is now valid syntax.)
6404
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006405- ctypes function pointers that are COM methods have a boolean True
6406 value again.
6407
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006408- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6409 by denying s# to parse objects that have a releasebuffer procedure,
6410 and introducing s*.
6411
Georg Brandl1e13ea92008-08-11 09:07:59 +00006412- Issue #3537: Fix an assertion failure when an empty but presized dict
6413 object was stored in the freelist.
6414
Mark Dickinsonb6467572008-08-04 21:30:09 +00006415- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6416 ValueError consistently across platforms.
6417
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006418- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6419 (64bit Unix, for example), unichr() would truncate its argument and return
6420 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6421
Neal Norwitze7d8be82008-07-31 17:17:14 +00006422- Apply security patches from Apple.
6423
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006424- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6425 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6426
Antoine Pitrou92f82162008-07-25 22:22:08 +00006427- Issue #1819: function calls with several named parameters are now on
6428 average 35% faster (as measured by pybench).
6429
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006430- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6431 the python debugger steps into a class statement: the free variables (local
6432 variables defined in an outer scope) would be deleted from the outer scope.
6433
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006434- Issue #2620: Overflow checking when allocating or reallocating memory
6435 was not always being done properly in some python types and extension
6436 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6437 all been updated to perform better checks and places in the code that
6438 would previously leak memory on the error path when such an allocation
6439 failed have been fixed.

6442-------
6443
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006444- Issue #3612: Added some missing basic types in ctypes.wintypes.
6445
Benjamin Petersone977ad42008-08-20 01:42:01 +00006446- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6447 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6448
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006449- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6450 version reported by these tools does not necessarily follow the python
6451 version numbering scheme, so the module is less strict when parsing it.
6452
Nick Coghlanf70385a2008-08-18 12:42:46 +00006453- Issue #2235: Added Py3k warnings for types which will become unhashable
6454 under the stricter __hash__ inheritance rules in 3.0. Several types
6455 which did not meet the rules for hash invariants and were already
6456 unhashable in 3.0 have now been explicitly flagged as unhashable in
6457 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6458 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6459
Brett Cannon88f801d2008-08-18 00:46:22 +00006460- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6461 imported into the module but exposed as part of the module's API.
6462
Brett Cannon7b96f072008-08-18 00:41:11 +00006463- Remove an unneeded import of abc.ABCMeta from 'inspect'.

6468
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006469- Issue #3575: Incremental decoder's decode function now takes bytearray
6470 by using 's*' instead of 't#'.
6471
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006472- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006473 fails unicode conversion on 2nd parameter. (windows only)
6474
Georg Brandl222e2082010-08-01 22:27:39 +00006475- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006476 in a redirect.
6477
Brett Cannonabe423e2008-08-16 21:47:07 +00006478- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006479 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006480
Facundo Batistaeb90b782008-08-16 14:44:07 +00006481- Issue #2776: fixed small issue when handling an URL with double slash
6482 after a 302 response in the case of not going through a proxy.
6483
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006484- Issue #2676: in the email package, content-type parsing was hanging on
6485 pathological input because of quadratic or exponential behaviour of a
6486 regular expression.
6487
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006488- Issue #3476: binary buffered reading through the new "io" library is now
6489 thread-safe.
6490
Brett Cannonbf3157b2008-08-14 05:00:03 +00006491- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6492 since mimetools itself is deprecated. Because modules are cached, all
6493 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6494
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006495- Issue #3134: shutil referenced undefined WindowsError symbol.
6496
Robert Schuppenies14646332008-08-10 11:01:53 +00006497- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6498 menu entries were not deleted.
6499
Brett Cannon83e81842008-08-09 23:30:55 +00006500- Copied the implementation of reduce() to _functools.reduce() to have a
6501 version that did not raise a DeprecationWarning under -3.
6502
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006503- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6504 a MemoryError rather than silently stop the iteration.
6505
Guido van Rossum59ce9012008-08-09 14:55:34 +00006506- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6507 to _sre.compile() will now be rejected. This should not affect anybody
6508 since the re.compile() function never generates invalid re-bytecode.
6509
Skip Montanaroa032bf42008-08-08 22:52:51 +00006510- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6511 upon first access it can be automatically initialized from the csv file if
6512 it wasn't initialized during instantiation.
6513
Brett Cannon3aa2a492008-08-06 22:28:09 +00006514- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6515 the reload() built-in has been removed.
6516
Brett Cannon7e30b672008-08-04 21:52:25 +00006517- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006518 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006529 asking for a specific length. This problem only affected files opened
6530 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006531

6556 file name rather than a ZipInfo instance, so files are extracted with
6557 mode 0600 rather than 000 under Unix.
6558

6572 interaction with the tp_hash slot (added in 2.6b2) are now documented
6573
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006574- Issue #643841: The language reference now provides more detailed
6575 coverage of the lookup process for special methods. The disclaimers
6576 regarding lack of coverage of new-style classes have also been
6577 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006580What's New in Python 2.6 beta 2?
6581================================
6582
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006583*Release date: 17-Jul-2008*
6584
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006585Core and Builtins
6586-----------------
6587
Georg Brandl3e483f62008-07-16 22:57:41 +00006588- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6589 its methods now allow for items objects that can be converted to
6590 an integer using operator.index().
6591
Mark Dickinson64b7e502008-07-16 09:40:03 +00006592- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6593 produced a ValueError instead of giving the correct float.
6594
Eric Smitha5fa5a22008-07-16 00:11:49 +00006595- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6596 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6597
Mark Dickinson7103aa42008-07-15 19:08:33 +00006598- Issue #3008: the float type has a new instance method 'float.hex'
6599 and a new class method 'float.fromhex' to convert floating-point
6600 numbers to and from hexadecimal strings, respectively.
6601
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006602- Issue #2235: __hash__ is once again inherited by default. To allow
6603 collections.Hashable to remain meaningful in the presence of the
6604 default hash implementation (object.__hash__), it is now possible
6605 to explicit block inheritance of hash by setting __hash__=None at
6606 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6607 level.
6608
Nick Coghlanb028f502008-07-13 14:52:36 +00006609- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6610 the parent module cannot be found while performing an absolute import.
6611 This means that an incorrectly defined __package__ attribute will
6612 now only prevent relative imports in that module rather than causing
6613 all imports from that module to fail.
6614
Nick Coghlan14ff9942008-07-08 14:21:42 +00006615- Issue #2517: Allow unicode messages in Exceptions again by correctly
6616 bypassing the instance dictionary when looking up __unicode__ on
6617 new-style classes.
6618
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006619- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6620 set to a custom object whose write() method happens to install
6621 another file in sys.stdout.
6622
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006623- Issue #3088: Corrected a race condition in classes derived from
6624 threading.local: the first member set by a thread could be saved in
6625 another thread's dictionary.
6626
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006627- Issue #3004: Minor change to slice.indices(): the start and stop
6628 arguments are now treated identically, making the behaviour easier
6629 to describe and understand. For example, slice(None, -10,
6630 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6631 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6632 10, -1).
6633
Georg Brandl278fc502008-07-19 12:46:12 +00006634- Issue #3219: Calling a function with repeated keyword arguments,
6635 f(a=2, a=23), would not cause a syntax error. This was a regression
6636 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006637
Georg Brandl278fc502008-07-19 12:46:12 +00006638- Issue #2862: Make int and float freelist management consistent with
6639 other freelists. Changes their CompactFreeList apis into
6640 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006641

6643-------
6644
Thomas Heller57adf222008-08-14 19:10:48 +00006645- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6646 api functions without holding the GIL, which could lead to a fatal
6647 error when they failed.
6648
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006649- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006657- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6658 ForkingPickler.register() to resolve conflict with ctypes.
6659
Vinay Sajip51e65192008-07-18 09:01:10 +00006660- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006661
Thomas Heller880f5292008-07-15 19:39:38 +00006662- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6663 a valid dlerror() message.
6664
Thomas Heller2bad6572008-07-15 17:19:50 +00006665- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6666 incomplete structure was created.
6667
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006668- Issue #3339: dummy_thread.acquire() should not return None.
6669
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006670- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6671
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006672- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006673
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006674- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6675 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006676 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006677 content-length. The problem had been corrected in the 2.4 branch, but never
6678 merged into trunk.
6679
Georg Brandle78fbcc2008-07-05 10:13:36 +00006680- Issue #2663: add filtering capability to shutil.copytree().

6685
6686- Issue #1746: Correct handling of zipfile archive comments (previously
6687 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006688 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006689
Vinay Sajip51e65192008-07-18 09:01:10 +00006690- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006691 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006692
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006693- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6694 handling is now the same as that of other special attributes like __name__).
6695
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006696- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6697 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007148- Issue #1631171: Re-implement the 'warnings' module in C (the
7149 original Python code has been kept as backup). This will allow for
7150 using the 'warning's machinery in such places as the parser where
7151 use of pure Python code is not possible. Both the ``showarning()``
7152 and ``formatwarning()`` gain an optional 'line' argument which is
7153 not called by default for backwards-compatibility reasons. Setting
7154 ``warnings.showwarning()`` to an implementation that lacks support
7155 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007218- Issue #2550: The approach used by client/server code for obtaining
7219 ports to listen on in network-oriented tests has been refined in an
7220 effort to facilitate running multiple instances of the entire
7221 regression test suite in parallel without issue.
7222 test_support.bind_port() has been fixed such that it will always
7223 return a unique port -- which wasn't always the case with the
7224 previous implementation, especially if socket options had been set
7225 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7226 new implementation of bind_port() will actually raise an exception
7227 if it is passed an AF_INET/SOCK_STREAM socket with either the
7228 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7229 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7230 the socket it's been passed. This currently only applies to
7231 Windows. This option prevents any other sockets from binding to the
7232 host/port we've bound to, thus removing the possibility of the
7233 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7234 when a second SOCK_STREAM socket binds and accepts to a host/port
7235 that's already been bound by another socket. The optional preferred
7236 port parameter to bind_port() has been removed. Under no
7237 circumstances should tests be hard coding ports!
7238
7239 test_support.find_unused_port() has also been introduced, which will
7240 pass a temporary socket object to bind_port() in order to obtain an
7241 unused port. The temporary socket object is then closed and
7242 deleted, and the port is returned. This method should only be used
7243 for obtaining an unused port in order to pass to an external program
7244 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7245 a parameter to a server-oriented class that doesn't give you direct
7246 access to the underlying socket used.
7247
7248 Finally, test_support.HOST has been introduced, which should be used
7249 for the host argument of any relevant socket calls (i.e. bind and
7250 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007251
7252 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007253 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007254 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7255 test_asynchat and test_socket_ssl.
7256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007257 It is now possible for multiple instances of the regression test
7258 suite to run in parallel without issue.

7526
Fred Drakea8ee94b2008-03-01 02:45:07 +00007527- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007528 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00007537- Added the future_builtins module, which contains hex() and oct().
7538 These are the PEP 3127 version of these functions, designed to be
7539 compatible with the hex() and oct() builtins from Python 3.0. They
7540 differ slightly in their output formats from the existing, unchanged
7541 Python 2.6 builtins. The expected usage of the future_builtins
7542 module is:
7543 from future_builtins import hex, oct
7544
Eric Smith7ef40bf2008-02-20 23:34:22 +00007545- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7546 exponents for exponents with absolute value < 100. Follows C99
7547 standard. This is a change on Windows, which would use 3 digits.
7548 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7549 so that any alterations it does to the resulting string will be
7550 available in stringlib/formatter.h (for float.__format__).
7551
Eric Smith5a3c1352008-02-19 13:21:56 +00007552- Implemented PEP 3101, Advanced String Formatting. This adds a new
7553 builtin format(); a format() method for str and unicode; a
7554 __format__() method to object, str, unicode, int, long, float, and
7555 datetime; the class string.Formatter; and the C API
7556 PyObject_Format().
7557
Georg Brandl3ee81df2008-05-17 18:14:43 +00007558- Fixed several potential crashes, all caused by specially crafted
7559 __del__ methods exploiting objects in temporarily inconsistent
7560 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007561
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007562- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007563 prevent a possible crash: an Abstract Base Class would try to access
7564 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007565

Georg Brandl3ee81df2008-05-17 18:14:43 +00007569- Clear all free lists during a gc.collect() of the highest generation
7570 in order to allow pymalloc to free more arenas. Python may give back
7571 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007572
Georg Brandl3ee81df2008-05-17 18:14:43 +00007573- Issue #2045: Fix an infinite recursion triggered when printing a
7574 subclass of collections.defaultdict, if its default_factory is set
7575 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007576
Christian Heimesf75dbef2008-02-08 00:11:31 +00007577- Fixed a minor memory leak in dictobject.c. The content of the free
7578 list was not freed on interpreter shutdown.
7579
Georg Brandl21e99f42010-03-07 15:23:59 +00007580- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007581 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007582
Georg Brandl3ee81df2008-05-17 18:14:43 +00007583- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7584 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007585 to compact the internal free lists of pre-allocted ints and floats.
7586
Georg Brandl3ee81df2008-05-17 18:14:43 +00007587- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7588 calls. Python expected the return type int but the fork familie
7589 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007590
Georg Brandl3ee81df2008-05-17 18:14:43 +00007591- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7592 appear in the same code unit.

7601 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007602
Georg Brandl3ee81df2008-05-17 18:14:43 +00007603- Patch #1473257: generator objects gain a gi_code attribute. This is
7604 the same object as the func_code attribute of the function that
7605 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007606
Georg Brandl3ee81df2008-05-17 18:14:43 +00007607- Issue #1920: "while 0" statements were completely removed by the
7608 compiler, even in the presence of an "else" clause, which is
7609 supposed to be run when the condition is false. Now the compiler
7610 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007611
Guido van Rossumeead05f2008-01-24 18:21:02 +00007612- A few crashers fixed: weakref_in_del.py (issue #1377858);
7613 loosing_dict_ref.py (issue #1303614, test67.py);
7614 borrowed_ref_[34].py (not in tracker).
7615

7619
Georg Brandl3ee81df2008-05-17 18:14:43 +00007620- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007621 several extension methods and modules do not work without unicode
7622 support.
7623
Georg Brandl26543b12008-01-21 18:36:51 +00007624- Issue #1882: when compiling code from a string, encoding cookies in the

7626
Georg Brandl14404b62008-01-19 19:27:05 +00007627- Issue #1679: "0x" was taken as a valid integer literal.
7628
Georg Brandl6caad7d2008-01-26 14:19:22 +00007629- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007630 added.
7631
Christian Heimesc94e2b52008-01-14 04:13:37 +00007632- sys.float_info / PyFloat_GetInfo: The floating point information
7633 object was converted from a dict to a specialized structseq object.
7634
Georg Brandl3ee81df2008-05-17 18:14:43 +00007635- Patch #1816: Added sys.flags structseq. It exposes the status of
7636 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007637
Georg Brandl3ee81df2008-05-17 18:14:43 +00007638- Objects/structseq.c: Implemented new structseq representation. The
7639 patch makes structseqs (e.g. the return value of os.stat) more
7640 readable.

7649
Georg Brandl3ee81df2008-05-17 18:14:43 +00007650- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7651 envvar and sys.dont_write_bytecode attribute. All these can be set
7652 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007654- Improve some exception messages when Windows fails to load an
7655 extension module. Now we get for example '%1 is not a valid Win32
7656 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007664 and INF. float("nan"), float("inf") and float("-inf") now work on
7665 every platform with IEEE 754 semantics.

7669 dictionary size. There is a new opcode, STORE_MAP, for adding
7670 entries to the dictionary.

7700 file can now be directly executed by passing their name to the
7701 interpreter. The directory/zipfile is automatically inserted as the
7702 first entry in sys.path.

7713
Georg Brandl21e99f42010-03-07 15:23:59 +00007714- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7716 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007717
Georg Brandl3ee81df2008-05-17 18:14:43 +00007718- Issue #1686386: Tuple's tp_repr did not take into account the
7719 possibility of having a self-referential tuple, which is possible
7720 from C code. Nor did object's tp_str consider that a type's tp_str
7721 could do something that could lead to an inifinite recursion.
7722 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7723 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007724
Georg Brandl3ee81df2008-05-17 18:14:43 +00007725- Issue #1164: It was possible to trigger deadlock when using the
7726 'print' statement to write to a file since the GIL was not released
7727 as needed. Now PyObject_Print() does the right thing along with
7728 various tp_print implementations of the built-in types and those in
7729 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007730
Georg Brandl3ee81df2008-05-17 18:14:43 +00007731- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007738- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007739 PyObject_Call() never calling back out to Python code to trigger
7740 recursion depth updates/checks. Required the creation of a static
7741 RuntimeError instance in case normalizing an exception put the
7742 recursion check value past its limit. Fixes crashers
7743 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007758- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007759 __*__ attributes. (Some already existed, e.g., __doc__ and
7760 __name__.)

7764
Georg Brandl2134e752007-05-21 20:34:16 +00007765- Patch #1686487: you can now pass any mapping after '**' in function
7766 calls.
7767
Collin Winter62903052007-05-18 23:11:24 +00007768- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769 "except E as target:". This is to provide forwards compatibility
7770 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007777- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007778 setting a plain string, ie don't expand to single letter identifiers.
7779
Raymond Hettinger13936692007-04-11 18:40:58 +00007780- Request #1191699: Slices can now be pickled.
7781
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007782- Request #1193128: str.translate() now allows a None argument for
7783 translations that only remove characters without re-mapping the
7784 remaining characters.
7785
Georg Brandl5cb76c12007-03-21 09:00:39 +00007786- Patch #1682205: a TypeError while unpacking an iterable is no longer

7790
Guido van Rossum143b5642007-03-23 04:58:42 +00007791- Bug #1683368: The object.__init__() and object.__new__() methods are
7792 now stricter in rejecting excess arguments. The only time when
7793 either allows excess arguments is when it is not overridden and the
7794 other one is. For backwards compatibility, when both are
7795 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007796 warning later). Also, type.__init__() insists on the same signature
7797 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007799- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7800 object to complex using its __complex__() method before falling back
7801 to the __float__() method. Therefore, the functions in the cmath
7802 module now can operate on objects that define a __complex__()
7803 method.

7820
Georg Brandl7b9c5552007-03-12 14:30:05 +00007821- Bug #1678647: write a newline after printing an exception in any
7822 case, even when converting the value to a string failed.
7823
Georg Brandl871f1bc2007-03-12 13:17:36 +00007824- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007825 its argument, if it exists. If not, it will work like before. This
7826 allows customizing the output of dir() in the presence of a
7827 __getattr__().

7836 parthensized forms. This means complex(repr(x)) now works instead of
7837 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007838
Georg Brandlaa2321b2007-03-07 00:40:28 +00007839- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007840 makes the filenames the warning module prints much more sensible
7841 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007854- Patch #1674228: when assigning a slice (old-style), check for the
7855 sq_ass_slice instead of the sq_slice slot.
7856
Georg Brandl3ee81df2008-05-17 18:14:43 +00007857- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008392 AttributeError instead of an IOError when the server's response
8393 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008394

8409
Georg Brandl3ee81df2008-05-17 18:14:43 +00008410- Patch #1530482: add pydoc.render_doc() which returns the

8425
Georg Brandl92a6bae2007-03-13 17:43:32 +00008426- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008427 are set for invalid interpolation sequences that would lead to
8428 errors on reading back those values.

8471 returned string up to the first NUL character.

8482
Georg Brandl3ee81df2008-05-17 18:14:43 +00008483- unittest now verifies more of its assumptions. In particular,
8484 TestCase and TestSuite subclasses (not instances) are no longer
8485 accepted in TestSuite.addTest(). This should cause no
8486 incompatibility since it never made sense with ordinary subclasses
8487 -- the failure just occurred later, with a more cumbersome
8488 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008852- Marshal.dumps() now expects exact type matches for int, long, float,
8853 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8854 silently miscode subclasses of those types. Now, it raises a
8855 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008870- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008871 time so that opening a database previously created with the DB_DUP
8872 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8873 opens. Specifically: dictionary assignment to a DB object will
8874 replace all values for a given key when the database allows
8875 duplicate values. DB users should use DB.put(k, v) when they want
8876 to store duplicates; not DB[k] = v.

8883 characters with ASCII value less than 32. Also, it correctly quotes
8884 dots only if they occur on a single line, as opposed to the previous
8885 behavior of quoting dots if they are the second character of any
8886 line.

9241 of w# format code incorrectly truncated the length to an int, even
9242 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9243 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009273- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9274 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
