1091
1092- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1093 and later systems as is currently done for Python 3.x installers.
1094 For 2.7.7 only, we will provide three installers:
1095 the legacy deprecated 10.3+ 32-bit-only format;
1096 the newer 10.5+ 32-bit-only format;
1097 and the unchanged 10.6+ 64-/32-bit format.
1098 Although binary installers will no longer be available from
1099 python.org as of 2.7.8, it will still be possible to build from
1100 source on 10.3.9 and 10.4 systems if necessary.
1101 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08002481- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2482 In particular, fix extension module build failures when trying to use
2483 32-bit-only installer Pythons on systems with Xcode 4 (currently
2484 OS X 10.8, 10.7, and optionally 10.6).
2485 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2486 * Since Xcode 4 removes ppc support, extension module builds now
2487 check for ppc compiler support and by default remove ppc and
2488 ppc64 archs when they are not available.
2489 * Extension module builds now revert to using system installed
2490 headers and libs (/usr and /System/Library) if the SDK used
2491 to build the interpreter is not installed or has moved.
2492 * Try to avoid building extension modules with deprecated
2493 and problematic Apple llvm-gcc compiler. If original compiler
2494 is not available, use clang instead by default.

2862 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002938- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2939 Distutils-based packages with C extension modules may fail because
2940 Apple has removed gcc-4.2, the version used to build python.org
2941 64-bit/32-bit Pythons. If the user does not explicitly override
2942 the default C compiler by setting the CC environment variable,
2943 Distutils will now attempt to compile extension modules with clang
2944 if gcc-4.2 is required but not found. Also as a convenience, if
2945 the user does explicitly set CC, substitute its value as the default
2946 compiler in the Distutils LDSHARED configuration variable for OS X.
2947 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2948 SDK, neither of which are available in Xcode 4. This change does not
2949 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003199- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3200 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3201 interpreter process. This could cause failures in non-Distutils subprocesses
3202 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003203 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003204 deployment target only in the environment of each build subprocess. It is
3205 still possible to globally override the default by setting
3206 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3207 greater or equal to the default value, the value with which the interpreter
3208 was built.

3238 the ticker doesn't have to wind down to zero from the old starting point
3239 before the new interval takes effect. And if the user increases the
3240 interval, it makes sure the new limit takes effect right away rather have an
3241 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00004238- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4239 This prevents user-created self-referencing ordered dictionaries from
4240 becoming permanently uncollectable GC garbage. The downside is that
4241 removing __del__ means that the internal doubly-linked list has to wait for
4242 GC collection rather than freeing memory immediately when the refcnt drops
4243 to zero.

4704 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005087- Issue #7301: Add environment variable $PYTHONWARNINGS.
5088
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005089- Issue #8329: Don't return the same lists from select.select when no fds are
5090 changed.
5091
Georg Brandlfee0f442010-05-22 21:26:21 +00005092- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005093 on 64-bit machines. The shift count for either left or right shift is
5094 permitted to be up to sys.maxsize.

5101
Georg Brandlfee0f442010-05-22 21:26:21 +00005102- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5103 with a non-empty format string. This is an effort to future-proof user
5104 code. If a derived class does not currently implement __format__ but later
5105 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005106 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005107 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005140- Issue #8257: The Decimal construct now accepts a float instance directly,
5141 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005142

5145
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005146- collections.Counter() now supports a subtract() method.
5147
Georg Brandlfee0f442010-05-22 21:26:21 +00005148- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00005157- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5158 InvalidOperation instead of returning False. (Comparisons involving a quiet
5159 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5160 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005161
Georg Brandlfee0f442010-05-22 21:26:21 +00005162- Issue #2531: Comparison operations between floats and Decimal instances now
5163 return a result based on the numeric values of the operands; previously they
5164 returned an arbitrary result based on the relative ordering of id(float) and
5165 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005166
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005167- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005168 argument `-` which tells it to read files to compile from stdin. Each line is
5169 read on demand and the named file is compiled immediately. (Original patch by
5170 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00005175- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5176 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005177 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00005179- Comparisons using one of <, <=, >, >= between a complex instance and a
5180 Fractions instance now raise TypeError instead of returning True/False. This
5181 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5182 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00005539- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5540 and add the additional members returned in an OSVERSIONINFOEX structure. The
5541 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00005544- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5545 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5546 returning NULL. The macro now returns a statically allocated empty string
5547 instead.

5557 strings,
5558 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5559 numeric strings corresponding to subnormal values,
5560 (3) a memory leak for some values large enough to cause overflow, and
5561 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00005593 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005599- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005600 file position when calling `truncate()`. It would previously change the file
5601 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005602 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5603

5605 class used to represent files stored inside an archive. The new
5606 implementation is significantly faster and can be wrapped in a
5607 ``io.BufferedReader`` object for more speedups. It also solves an issue
5608 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5621 encoded string for them. This ensures that the upload and register commands
5622 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00005691What's New in Python 2.7 alpha 2?
5692=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00005694*Release date: 2010-01-09*

5697-----------------
5698
Georg Brandlba83f822010-03-14 09:50:54 +00005699- The ``__complex__()`` method is now looked up on the class of instances to
5700 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005701
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005702- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5703 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5704
Mark Dickinson1b34d252010-01-01 17:27:30 +00005705- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005706 DeprecationWarning when passed a float argument where an integer was expected.
5707 These functions and methods now raise TypeError instead. The majority of the
5708 effects of this change are in the extension modules, but some core functions
5709 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5710 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00005711
Benjamin Peterson0f02d392009-12-30 19:34:10 +00005712- Issue #7604: Deleting an unset slotted attribute did not raise an

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00005720- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
5721 used to drop the time part of the result.
5722
Georg Brandlba83f822010-03-14 09:50:54 +00005723- Issue #1811: Improve accuracy and cross-platform consistency for true division
5724 of integers: the result of a/b is now correctly rounded for ints a and b (at
5725 least on IEEE 754 platforms), and in particular does not depend on the
5726 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005727
Georg Brandlba83f822010-03-14 09:50:54 +00005728- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
5729 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
5730 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00005731

Ronald Oussoren92919a62009-12-24 13:30:58 +00005733 executables on OSX.
5734
Georg Brandlba83f822010-03-14 09:50:54 +00005735 These executables now work properly with the arch(1) command: ``arch -ppc
5736 python`` will start a universal binary version of python in PPC mode (unlike
5737 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005738
Georg Brandlba83f822010-03-14 09:50:54 +00005739- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
5740 underlying error when the coercion fails for the left hand operand.

5751 allowing for a maximum number of tasks within the pool to be completed by the
5752 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00005758- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00005759 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
5760 alternative to cPickle if you care about performance. Patch by Florent

5797 the same as passing no argument.
5798
Georg Brandlba83f822010-03-14 09:50:54 +00005799- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00005892- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5893 decimal string that's guaranteed to round back to x under correct rounding
5894 (with round-half-to-even rounding mode). Previously it gave a string based on
5895 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5896 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5897 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005898
Georg Brandlba83f822010-03-14 09:50:54 +00005899- Issue #7117: On almost all platforms: float-to-string and string-to-float
5900 conversions within Python are now correctly rounded. Places these conversions
5901 occur include: str for floats and complex numbers; the float and complex
5902 constructors; old-style and new-style numeric formatting; serialization and
5903 deserialization of floats and complex numbers using marshal, pickle and json;
5904 parsing of float and imaginary literals in Python code; Decimal-to-float
5905 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005906
Georg Brandlba83f822010-03-14 09:50:54 +00005907 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5908 providing correctly-rounded strtod and dtoa C functions. This code is
5909 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5910 the C compiler. There may be a small number of platforms on which correct
5911 operation of this code cannot be guaranteed, so the code is not used: notably,
5912 this applies to platforms where the C double format is not IEEE 754 binary64,
5913 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5914 and Python's configure script is unable to determine how to change the FPU
5915 precision. On these platforms conversions use the platform strtod and dtoa,
5916 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005917
Georg Brandlba83f822010-03-14 09:50:54 +00005918- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5919 uses the correctly-rounded string <-> float conversions described above (when
5920 available), and so produces correctly rounded results that will display nicely
5921 under the float repr. There are two related small changes: (1) round now
5922 accepts any class with an ``__index__()`` method for its second argument (but
5923 no longer accepts floats for the second argument), and (2) an excessively
5924 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

6152 internal representation of integers, for performance reasons. Base 2**30 is
6153 enabled by default on 64-bit machines. Add --enable-big-digits option to
6154 configure, which overrides the default. Add sys.long_info structseq to
6155 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006218- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
6219 existing .py counterpart, override the co_filename attributes of all code
6220 objects if the original filename is obsolete (which can happen if the file has

6275
Georg Brandlba83f822010-03-14 09:50:54 +00006276- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6277 file objects with closefd=False. The file descriptor is still kept open but
6278 the file object behaves like a closed file. The ``FileIO`` object also got a
6279 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00006302- On windows, ``os.chdir()`` given unicode was not working if
6303 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6304 this code path is really executed because I cannot move to such directory on
6305 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006307- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6308 element is temporarily replaced with an equivalent frozenset. But the
6309 eventual KeyError would always report the empty ``frozenset()`` as the missing

6331 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6332 step. This avoids problems with counting UTF-8 bytes that ignores the effect

6334
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006335- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00007522- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Georg Brandlba83f822010-03-14 09:50:54 +00007526 - Packing a float now always gives a Deprecation Warning. Previously it
7527 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00007529 - If x is not an int, long or float, then packing x will always result in
7530 struct.error. Previously an x with an __int__ method could be packed by
7531 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
7532 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7533 neither __int__ nor __long__, TypeError used to be raised (with a
7534 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7535 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00007537 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
7538 argument with an __int__ method can be packed, but use of this feature
7539 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007732- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7734 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Brett Cannon672237d2008-09-09 00:49:16 +00007807 return a list or None rather than a custom object.
7808

Brett Cannon1eaf0742008-09-02 01:25:16 +00007833 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7834 for catch_warnings() also led to an improvement in the raising of a
7835 DeprecationWarning related to warnings.warn_explicit().
7836
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007837- The deprecation warnings for the old camelCase threading API were removed.

7859
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007860- Issue #2975: When compiling several extension modules with Visual Studio 2008
7861 from the same python interpreter, some environment variables would grow
7862 without limit.
7863
Benjamin Peterson37346b22008-08-23 20:27:43 +00007864- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7865 exploitation of poor argument checking.
7866

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007901What's New in Python 2.6 beta 3?
7902================================
7903
Barry Warsaw07a4a382008-08-21 01:15:08 +00007904*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007905
7906Core and Builtins
7907-----------------
7908
Guido van Rossumf8402962008-08-20 15:01:50 +00007909- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7910 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7911 extensions do not automatically benefit from the class attribute
7912 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7913 to their tp_flags field if they care. This is a backwards
7914 compatibility feature; in 3.0, all types will use the cache by
7915 default.
7916
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007917- Keyword arguments can now follow starred arguments. (``f(a, *args,
7918 keyword=23)`` is now valid syntax.)
7919
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007920- ctypes function pointers that are COM methods have a boolean True
7921 value again.
7922
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007923- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7924 by denying s# to parse objects that have a releasebuffer procedure,
7925 and introducing s*.
7926
Georg Brandl1e13ea92008-08-11 09:07:59 +00007927- Issue #3537: Fix an assertion failure when an empty but presized dict
7928 object was stored in the freelist.
7929
Mark Dickinsonb6467572008-08-04 21:30:09 +00007930- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7931 ValueError consistently across platforms.
7932
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007933- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7934 (64bit Unix, for example), unichr() would truncate its argument and return
7935 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7936
Neal Norwitze7d8be82008-07-31 17:17:14 +00007937- Apply security patches from Apple.
7938
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007939- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7940 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7941
Antoine Pitrou92f82162008-07-25 22:22:08 +00007942- Issue #1819: function calls with several named parameters are now on
7943 average 35% faster (as measured by pybench).
7944
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007945- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7946 the python debugger steps into a class statement: the free variables (local
7947 variables defined in an outer scope) would be deleted from the outer scope.
7948
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007949- Issue #2620: Overflow checking when allocating or reallocating memory
7950 was not always being done properly in some python types and extension
7951 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7952 all been updated to perform better checks and places in the code that
7953 would previously leak memory on the error path when such an allocation
7954 failed have been fixed.
7955

7957-------
7958
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007959- Issue #3612: Added some missing basic types in ctypes.wintypes.
7960
Benjamin Petersone977ad42008-08-20 01:42:01 +00007961- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7962 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7963
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007964- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7965 version reported by these tools does not necessarily follow the python
7966 version numbering scheme, so the module is less strict when parsing it.
7967
Nick Coghlanf70385a2008-08-18 12:42:46 +00007968- Issue #2235: Added Py3k warnings for types which will become unhashable
7969 under the stricter __hash__ inheritance rules in 3.0. Several types
7970 which did not meet the rules for hash invariants and were already
7971 unhashable in 3.0 have now been explicitly flagged as unhashable in
7972 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7973 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7974
Brett Cannon88f801d2008-08-18 00:46:22 +00007975- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7977
Brett Cannon7b96f072008-08-18 00:41:11 +00007978- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7979
Brett Cannon46225e72008-08-18 00:36:52 +00007980- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007982- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7983
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007984- Issue #3575: Incremental decoder's decode function now takes bytearray
7985 by using 's*' instead of 't#'.
7986
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007987- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007988 fails unicode conversion on 2nd parameter. (windows only)
7989
Georg Brandl222e2082010-08-01 22:27:39 +00007990- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007991 in a redirect.
7992
Brett Cannonabe423e2008-08-16 21:47:07 +00007993- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007994 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007995
Facundo Batistaeb90b782008-08-16 14:44:07 +00007996- Issue #2776: fixed small issue when handling an URL with double slash
7997 after a 302 response in the case of not going through a proxy.
7998
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007999- Issue #2676: in the email package, content-type parsing was hanging on
8000 pathological input because of quadratic or exponential behaviour of a
8001 regular expression.
8002
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008003- Issue #3476: binary buffered reading through the new "io" library is now
8004 thread-safe.
8005
Brett Cannonbf3157b2008-08-14 05:00:03 +00008006- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8007 since mimetools itself is deprecated. Because modules are cached, all
8008 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8009
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008010- Issue #3134: shutil referenced undefined WindowsError symbol.
8011
Robert Schuppenies14646332008-08-10 11:01:53 +00008012- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8013 menu entries were not deleted.
8014
Brett Cannon83e81842008-08-09 23:30:55 +00008015- Copied the implementation of reduce() to _functools.reduce() to have a
8016 version that did not raise a DeprecationWarning under -3.
8017
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008018- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8019 a MemoryError rather than silently stop the iteration.
8020
Guido van Rossum59ce9012008-08-09 14:55:34 +00008021- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8022 to _sre.compile() will now be rejected. This should not affect anybody
8023 since the re.compile() function never generates invalid re-bytecode.
8024
Skip Montanaroa032bf42008-08-08 22:52:51 +00008025- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8026 upon first access it can be automatically initialized from the csv file if
8027 it wasn't initialized during instantiation.
8028
Brett Cannon3aa2a492008-08-06 22:28:09 +00008029- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8030 the reload() built-in has been removed.
8031
Brett Cannon7e30b672008-08-04 21:52:25 +00008032- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008033 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00008044 asking for a specific length. This problem only affected files opened
8045 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008046
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00008047- Issue #3449: Update decimal module to use most recent specification
8048 (v. 1.68) and tests (v. 2.58) from IBM.
8049

8054
Georg Brandlf9efabb2008-07-23 15:16:45 +00008055- Deprecate the "ast" parser function aliases.

8069
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008070- Issue #3394: zipfile.writestr sets external attributes when passed a
8071 file name rather than a ZipInfo instance, so files are extracted with
8072 mode 0600 rather than 000 under Unix.
8073
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008074- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8075 argument in python 2.5, this broke code that subclassed Popen to include its
8076 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008089- Issue #643841: The language reference now provides more detailed
8090 coverage of the lookup process for special methods. The disclaimers
8091 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008095What's New in Python 2.6 beta 2?
8096================================
8097
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008098*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008100Core and Builtins
8101-----------------
8102
Georg Brandl3e483f62008-07-16 22:57:41 +00008103- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8104 its methods now allow for items objects that can be converted to
8105 an integer using operator.index().
8106
Mark Dickinson64b7e502008-07-16 09:40:03 +00008107- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8108 produced a ValueError instead of giving the correct float.
8109
Eric Smitha5fa5a22008-07-16 00:11:49 +00008110- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8111 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8112
Mark Dickinson7103aa42008-07-15 19:08:33 +00008113- Issue #3008: the float type has a new instance method 'float.hex'
8114 and a new class method 'float.fromhex' to convert floating-point
8115 numbers to and from hexadecimal strings, respectively.
8116
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008117- Issue #2235: __hash__ is once again inherited by default. To allow
8118 collections.Hashable to remain meaningful in the presence of the
8119 default hash implementation (object.__hash__), it is now possible
8120 to explicit block inheritance of hash by setting __hash__=None at
8121 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8122 level.
8123
Nick Coghlanb028f502008-07-13 14:52:36 +00008124- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8125 the parent module cannot be found while performing an absolute import.
8126 This means that an incorrectly defined __package__ attribute will
8127 now only prevent relative imports in that module rather than causing
8128 all imports from that module to fail.
8129
Nick Coghlan14ff9942008-07-08 14:21:42 +00008130- Issue #2517: Allow unicode messages in Exceptions again by correctly
8131 bypassing the instance dictionary when looking up __unicode__ on
8132 new-style classes.

8135 set to a custom object whose write() method happens to install
8136 another file in sys.stdout.
8137
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008138- Issue #3088: Corrected a race condition in classes derived from
8139 threading.local: the first member set by a thread could be saved in
8140 another thread's dictionary.
8141
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008142- Issue #3004: Minor change to slice.indices(): the start and stop
8143 arguments are now treated identically, making the behaviour easier
8144 to describe and understand. For example, slice(None, -10,
8145 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8146 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8147 10, -1).
8148
Georg Brandl278fc502008-07-19 12:46:12 +00008149- Issue #3219: Calling a function with repeated keyword arguments,
8150 f(a=2, a=23), would not cause a syntax error. This was a regression
8151 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008152
Georg Brandl278fc502008-07-19 12:46:12 +00008153- Issue #2862: Make int and float freelist management consistent with
8154 other freelists. Changes their CompactFreeList apis into
8155 ClearFreeList apis and calls them via gc.collect().

8161 api functions without holding the GIL, which could lead to a fatal
8162 error when they failed.
8163
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008164- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00008175- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008176

8186
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008187- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008188
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008189- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8190 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008191 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008192 content-length. The problem had been corrected in the 2.4 branch, but never
8193 merged into trunk.
8194
Georg Brandle78fbcc2008-07-05 10:13:36 +00008195- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00008207
Nick Coghlanc060b0e2008-07-02 13:09:19 +00008208- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8209 handling is now the same as that of other special attributes like __name__).
8210
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008211- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

8661 original Python code has been kept as backup). This will allow for
8662 using the 'warning's machinery in such places as the parser where
8663 use of pure Python code is not possible. Both the ``showarning()``
8664 and ``formatwarning()`` gain an optional 'line' argument which is
8665 not called by default for backwards-compatibility reasons. Setting
8666 ``warnings.showwarning()`` to an implementation that lacks support
8667 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008730- Issue #2550: The approach used by client/server code for obtaining
8731 ports to listen on in network-oriented tests has been refined in an
8732 effort to facilitate running multiple instances of the entire
8733 regression test suite in parallel without issue.
8734 test_support.bind_port() has been fixed such that it will always
8735 return a unique port -- which wasn't always the case with the
8736 previous implementation, especially if socket options had been set
8737 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8738 new implementation of bind_port() will actually raise an exception
8739 if it is passed an AF_INET/SOCK_STREAM socket with either the
8740 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8741 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8742 the socket it's been passed. This currently only applies to
8743 Windows. This option prevents any other sockets from binding to the
8744 host/port we've bound to, thus removing the possibility of the
8745 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8746 when a second SOCK_STREAM socket binds and accepts to a host/port
8747 that's already been bound by another socket. The optional preferred
8748 port parameter to bind_port() has been removed. Under no
8749 circumstances should tests be hard coding ports!
8750
8751 test_support.find_unused_port() has also been introduced, which will
8752 pass a temporary socket object to bind_port() in order to obtain an
8753 unused port. The temporary socket object is then closed and
8754 deleted, and the port is returned. This method should only be used
8755 for obtaining an unused port in order to pass to an external program
8756 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8757 a parameter to a server-oriented class that doesn't give you direct
8758 access to the underlying socket used.
8759
8760 Finally, test_support.HOST has been introduced, which should be used
8761 for the host argument of any relevant socket calls (i.e. bind and
8762 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008763
8764 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008765 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008766 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8767 test_asynchat and test_socket_ssl.
8768
Georg Brandl3ee81df2008-05-17 18:14:43 +00008769 It is now possible for multiple instances of the regression test
8770 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009049- Added the future_builtins module, which contains hex() and oct().
9050 These are the PEP 3127 version of these functions, designed to be
9051 compatible with the hex() and oct() builtins from Python 3.0. They
9052 differ slightly in their output formats from the existing, unchanged
9053 Python 2.6 builtins. The expected usage of the future_builtins
9054 module is:
9055 from future_builtins import hex, oct
9056
Eric Smith7ef40bf2008-02-20 23:34:22 +00009057- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9058 exponents for exponents with absolute value < 100. Follows C99
9059 standard. This is a change on Windows, which would use 3 digits.
9060 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9061 so that any alterations it does to the resulting string will be
9062 available in stringlib/formatter.h (for float.__format__).
9063
Eric Smith5a3c1352008-02-19 13:21:56 +00009064- Implemented PEP 3101, Advanced String Formatting. This adds a new
9065 builtin format(); a format() method for str and unicode; a
9066 __format__() method to object, str, unicode, int, long, float, and
9067 datetime; the class string.Formatter; and the C API
9068 PyObject_Format().
9069
Georg Brandl3ee81df2008-05-17 18:14:43 +00009070- Fixed several potential crashes, all caused by specially crafted
9071 __del__ methods exploiting objects in temporarily inconsistent
9072 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009073
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009074- Issue #2115: Important speedup in setting __slot__ attributes. Also

9082 in order to allow pymalloc to free more arenas. Python may give back
9083 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009084
Georg Brandl3ee81df2008-05-17 18:14:43 +00009085- Issue #2045: Fix an infinite recursion triggered when printing a
9086 subclass of collections.defaultdict, if its default_factory is set
9087 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009088
Christian Heimesf75dbef2008-02-08 00:11:31 +00009089- Fixed a minor memory leak in dictobject.c. The content of the free

9096 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009097 to compact the internal free lists of pre-allocted ints and floats.
9098
Georg Brandl3ee81df2008-05-17 18:14:43 +00009099- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9100 calls. Python expected the return type int but the fork familie
9101 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009115- Patch #1473257: generator objects gain a gi_code attribute. This is
9116 the same object as the func_code attribute of the function that
9117 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009118
Georg Brandl3ee81df2008-05-17 18:14:43 +00009119- Issue #1920: "while 0" statements were completely removed by the
9120 compiler, even in the presence of an "else" clause, which is
9121 supposed to be run when the condition is false. Now the compiler
9122 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009123
Guido van Rossumeead05f2008-01-24 18:21:02 +00009124- A few crashers fixed: weakref_in_del.py (issue #1377858);

9131
Georg Brandl3ee81df2008-05-17 18:14:43 +00009132- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009133 several extension methods and modules do not work without unicode
9134 support.
9135

9140
Georg Brandl6caad7d2008-01-26 14:19:22 +00009141- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009142 added.
9143
Christian Heimesc94e2b52008-01-14 04:13:37 +00009144- sys.float_info / PyFloat_GetInfo: The floating point information
9145 object was converted from a dict to a specialized structseq object.
9146
Georg Brandl3ee81df2008-05-17 18:14:43 +00009147- Patch #1816: Added sys.flags structseq. It exposes the status of
9148 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009149
Georg Brandl3ee81df2008-05-17 18:14:43 +00009150- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- Patch #1700288: added a type attribute cache that caches method
9155 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009156
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009157- Bug #1776: __import__() no longer accepts filenames on any platform.
9158 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00009160- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9161
Georg Brandl3ee81df2008-05-17 18:14:43 +00009162- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9163 envvar and sys.dont_write_bytecode attribute. All these can be set
9164 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009165
Georg Brandl3ee81df2008-05-17 18:14:43 +00009166- Improve some exception messages when Windows fails to load an
9167 extension module. Now we get for example '%1 is not a valid Win32
9168 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009175- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009176 and INF. float("nan"), float("inf") and float("-inf") now work on
9177 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009178
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179- Compiler now generates simpler and faster code for dictionary
9180 literals. The oparg for BUILD_MAP now indicates an estimated
9181 dictionary size. There is a new opcode, STORE_MAP, for adding
9182 entries to the dictionary.

9194
Nick Coghlanef01d822007-12-03 12:55:17 +00009195- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Patch #1739468: Directories and zipfiles containing a __main__.py
9212 file can now be directly executed by passing their name to the
9213 interpreter. The directory/zipfile is automatically inserted as the
9214 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009215
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216- Issue #1265: Fix a problem with sys.settrace, if the tracing
9217 function uses a generator expression when at the same time the
9218 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009219
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009220- sets and frozensets now have an isdisjoint() method.
9221
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009222- optimize the performance of builtin.sum().
9223
Neal Norwitz44f326e2007-10-05 05:29:17 +00009224- Fix warnings found by the new version of the Coverity checker.
9225
Georg Brandl21e99f42010-03-07 15:23:59 +00009226- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009227 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9228 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009229
Georg Brandl3ee81df2008-05-17 18:14:43 +00009230- Issue #1686386: Tuple's tp_repr did not take into account the
9231 possibility of having a self-referential tuple, which is possible
9232 from C code. Nor did object's tp_str consider that a type's tp_str
9233 could do something that could lead to an inifinite recursion.
9234 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9235 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009236
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237- Issue #1164: It was possible to trigger deadlock when using the
9238 'print' statement to write to a file since the GIL was not released
9239 as needed. Now PyObject_Print() does the right thing along with
9240 various tp_print implementations of the built-in types and those in
9241 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009242
Georg Brandl3ee81df2008-05-17 18:14:43 +00009243- Issue #1147: Exceptions were directly allowing string exceptions in
9244 their throw() method even though string exceptions no longer
9245 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009246
Georg Brandl3ee81df2008-05-17 18:14:43 +00009247- Issue #1096: Prevent a segfault from getting the repr of a very
9248 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009249
Brett Cannon1e534b52007-09-07 04:18:30 +00009250- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009251 PyObject_Call() never calling back out to Python code to trigger
9252 recursion depth updates/checks. Required the creation of a static
9253 RuntimeError instance in case normalizing an exception put the
9254 recursion check value past its limit. Fixes crashers
9255 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009257- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009270- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009271 __*__ attributes. (Some already existed, e.g., __doc__ and
9272 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009273
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009274- Add -3 option to the interpreter to warn about features that are
9275 deprecated and will be changed/removed in Python 3.0.
9276
Georg Brandl2134e752007-05-21 20:34:16 +00009277- Patch #1686487: you can now pass any mapping after '**' in function
9278 calls.
9279
Collin Winter62903052007-05-18 23:11:24 +00009280- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009281 "except E as target:". This is to provide forwards compatibility
9282 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009283
Brett Cannon229cee22007-05-05 01:34:02 +00009284- Deprecate BaseException.message as per PEP 352.
9285
Georg Brandl3ee81df2008-05-17 18:14:43 +00009286- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009287 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009288
Vinay Sajip8549ce32007-05-06 17:53:37 +00009289- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009290 setting a plain string, ie don't expand to single letter identifiers.
9291
Raymond Hettinger13936692007-04-11 18:40:58 +00009292- Request #1191699: Slices can now be pickled.
9293
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009294- Request #1193128: str.translate() now allows a None argument for
9295 translations that only remove characters without re-mapping the
9296 remaining characters.
9297
Georg Brandl5cb76c12007-03-21 09:00:39 +00009298- Patch #1682205: a TypeError while unpacking an iterable is no longer
9299 masked by a generic one with the message "unpack non-sequence".
9300
Neal Norwitzaa754b72007-03-21 06:39:48 +00009301- Remove unused file Python/fmod.c.
9302
Guido van Rossum143b5642007-03-23 04:58:42 +00009303- Bug #1683368: The object.__init__() and object.__new__() methods are
9304 now stricter in rejecting excess arguments. The only time when
9305 either allows excess arguments is when it is not overridden and the
9306 other one is. For backwards compatibility, when both are
9307 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009308 warning later). Also, type.__init__() insists on the same signature
9309 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009310
Georg Brandl3ee81df2008-05-17 18:14:43 +00009311- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9312 object to complex using its __complex__() method before falling back
9313 to the __float__() method. Therefore, the functions in the cmath
9314 module now can operate on objects that define a __complex__()
9315 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009316
Georg Brandl3ee81df2008-05-17 18:14:43 +00009317- Patch #1623563: allow __class__ assignment for classes with
9318 __slots__. The old and the new class are still required to have the
9319 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009320
Georg Brandl3ee81df2008-05-17 18:14:43 +00009321- Patch #1642547: Fix an error/crash when encountering syntax errors

9325 ``object.__reduce_ex__()`` is called with an object that is faking
9326 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009327
Georg Brandl3ee81df2008-05-17 18:14:43 +00009328- Patch #1680015: Don't modify __slots__ tuple if it contains an

9332
Georg Brandl7b9c5552007-03-12 14:30:05 +00009333- Bug #1678647: write a newline after printing an exception in any
9334 case, even when converting the value to a string failed.
9335
Georg Brandl871f1bc2007-03-12 13:17:36 +00009336- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009337 its argument, if it exists. If not, it will work like before. This
9338 allows customizing the output of dir() in the presence of a
9339 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009340
Collin Winter276887b2007-03-12 16:11:39 +00009341- Patch #922167: Python no longer segfaults when faced with infinitely
9342 self-recursive reload() calls (as reported by bug #742342).
9343
Georg Brandl3ee81df2008-05-17 18:14:43 +00009344- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009347- Patch #1491866: change the complex() constructor to allow
9348 parthensized forms. This means complex(repr(x)) now works instead of
9349 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009350
Georg Brandlaa2321b2007-03-07 00:40:28 +00009351- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009352 makes the filenames the warning module prints much more sensible
9353 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009354
Georg Brandl49aafc92007-03-07 00:34:46 +00009355- Variant of patch #697613: don't exit the interpreter on a SystemExit
9356 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009357 variable is given, but break into the interactive interpreter just
9358 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00009365
Georg Brandl0fca97a2007-03-05 22:28:08 +00009366- Patch #1674228: when assigning a slice (old-style), check for the
9367 sq_ass_slice instead of the sq_slice slot.
9368
Georg Brandl3ee81df2008-05-17 18:14:43 +00009369- When printing an unraisable error, don't print exceptions. before
9370 the name. This duplicates the behavior whening normally printing
9371 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00009937- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009938 are set for invalid interpolation sequences that would lead to
9939 errors on reading back those values.

9993
Georg Brandl3ee81df2008-05-17 18:14:43 +00009994- unittest now verifies more of its assumptions. In particular,
9995 TestCase and TestSuite subclasses (not instances) are no longer
9996 accepted in TestSuite.addTest(). This should cause no

9998 -- the failure just occurred later, with a more cumbersome
9999 exception.

10364 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10365 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010381- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010382 time so that opening a database previously created with the DB_DUP
10383 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10384 opens. Specifically: dictionary assignment to a DB object will
10385 replace all values for a given key when the database allows
10386 duplicate values. DB users should use DB.put(k, v) when they want
10387 to store duplicates; not DB[k] = v.

10396 behavior of quoting dots if they are the second character of any
10397 line.
