580 Distutils-based packages with C extension modules may fail because
581 Apple has removed gcc-4.2, the version used to build python.org
582 64-bit/32-bit Pythons. If the user does not explicitly override
583 the default C compiler by setting the CC environment variable,
584 Distutils will now attempt to compile extension modules with clang
585 if gcc-4.2 is required but not found. Also as a convenience, if
586 the user does explicitly set CC, substitute its value as the default
587 compiler in the Distutils LDSHARED configuration variable for OS X.
588 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
589 SDK, neither of which are available in Xcode 4. This change does not
590 attempt to override settings to support their use with Xcode 4.)

864 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
865 interpreter process. This could cause failures in non-Distutils subprocesses
866 and was unreliable since tests or user programs could modify the interpreter
867 environment after Distutils set it. Instead, have Distutils set the the
868 deployment target only in the environment of each build subprocess. It is
869 still possible to globally override the default by setting
870 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
871 greater or equal to the default value, the value with which the interpreter
872 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400900- sys.setcheckinterval() now updates the current ticker count as well as

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

1855
Raymond Hettinger20397532010-09-12 02:11:45 +00001856- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1857 This prevents user-created self-referencing ordered dictionaries from
1858 becoming permanently uncollectable GC garbage. The downside is that
1859 removing __del__ means that the internal doubly-linked list has to wait for
1860 GC collection rather than freeing memory immediately when the refcnt drops
1861 to zero.
1862
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001863- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1866
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001867- Issue #9792: In case of connection failure, socket.create_connection()
1868 would swallow the exception and raise a new one, making it impossible
1869 to fetch the original errno, or to filter timeout errors. Now the
1870 original error is re-raised.
1871
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001872- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1873 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1874 be updated back after the system call. Original patch by Brian Brazil.

1881
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001882- Issue #808164: Fixed socket.close to avoid references to globals, to
1883 avoid issues when socket.close is called from a __del__ method.
1884

1886 can be set to False to turn off the previously undocumented 'popularity'
1887 heuristic. Patch by Terry Reedy and Eli Bendersky
1888

1890 falling into recursion.
1891
R. David Murray7c4bf552010-08-25 01:45:57 +00001892- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1893 character years even if the message contains RFC822 two character years.
1894
Daniel Stutzbach91287322010-08-24 21:09:30 +00001895- Issue #8750: Fixed MutableSet's methods to correctly handle

1908
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001909- Issue #9617: Signals received during a low-level write operation aren't
1910 ignored by the buffered IO layer anymore.
1911
Benjamin Peterson52c36052010-08-21 03:03:22 +00001912- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1913 are not held onto after they are deleted elsewhere.
1914
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001915- Issue #9626: the view methods for collections.OrderedDict() were returning

Éric Araujo0389ae62010-08-14 03:07:46 +00001919- Issue #8688: MANIFEST files created by distutils now include a magic
1920 comment indicating they are generated. Manually maintained MANIFESTs
1921 without this marker will not be overwritten or removed.
1922
Antoine Pitroue1436d12010-08-12 15:25:51 +00001923- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1924 and a BadZipfile error is raised if it doesn't match (as used to be the
1925 case in Python 2.5 and earlier).
1926
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001927- Issue #9550: a BufferedReader could issue an additional read when the
1928 original read request had been satisfied, which could block indefinitely
1929 when the underlying raw IO channel was e.g. a socket. Report and original
1930 patch by Jason V. Miller.
1931
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001932- Issue #9551: Don't raise TypeError when setting the value to None for

1951 This is how it is supposed to work, wget and curl do the same. Previous
1952 behavior was wrong.

1960 the option character for the added 'h/help' option if prefix_chars
1961 does not contain a '-', instead of raising an error.
1962

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002681 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002706- Issue #7301: Add environment variable $PYTHONWARNINGS.
2707
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002708- Issue #8329: Don't return the same lists from select.select when no fds are
2709 changed.
2710
Georg Brandlfee0f442010-05-22 21:26:21 +00002711- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002712 on 64-bit machines. The shift count for either left or right shift is
2713 permitted to be up to sys.maxsize.
2714
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002715- Ensure that tokenization of identifiers is not affected by locale.

2720
Georg Brandlfee0f442010-05-22 21:26:21 +00002721- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2722 with a non-empty format string. This is an effort to future-proof user
2723 code. If a derived class does not currently implement __format__ but later
2724 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002725 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002726 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002759- Issue #8257: The Decimal construct now accepts a float instance directly,
2760 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002761

2764
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002765- collections.Counter() now supports a subtract() method.
2766
Georg Brandlfee0f442010-05-22 21:26:21 +00002767- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00002776- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2777 InvalidOperation instead of returning False. (Comparisons involving a quiet
2778 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2779 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002780
Georg Brandlfee0f442010-05-22 21:26:21 +00002781- Issue #2531: Comparison operations between floats and Decimal instances now
2782 return a result based on the numeric values of the operands; previously they
2783 returned an arbitrary result based on the relative ordering of id(float) and
2784 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002785
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002786- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002787 argument `-` which tells it to read files to compile from stdin. Each line is
2788 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00002794- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2795 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002796 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00002798- Comparisons using one of <, <=, >, >= between a complex instance and a
2799 Fractions instance now raise TypeError instead of returning True/False. This
2800 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2801 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003158- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3159 and add the additional members returned in an OSVERSIONINFOEX structure. The
3160 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003163- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3164 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3165 returning NULL. The macro now returns a statically allocated empty string
3166 instead.

3176 strings,
3177 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3178 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00003211- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003212 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003218- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003219 file position when calling `truncate()`. It would previously change the file
3220 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003221 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3222
Georg Brandlba83f822010-03-14 09:50:54 +00003223- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3224 class used to represent files stored inside an archive. The new
3225 implementation is significantly faster and can be wrapped in a
3226 ``io.BufferedReader`` object for more speedups. It also solves an issue
3227 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003238- Issue #7748: Since unicode values are supported for some metadata options in
3239 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3240 encoded string for them. This ensures that the upload and register commands
3241 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00003310What's New in Python 2.7 alpha 2?
3311=================================
3312
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00003313*Release date: 2010-01-09*

3316-----------------
3317
Georg Brandlba83f822010-03-14 09:50:54 +00003318- The ``__complex__()`` method is now looked up on the class of instances to
3319 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003320
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003321- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3322 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3323
Mark Dickinson1b34d252010-01-01 17:27:30 +00003324- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003325 DeprecationWarning when passed a float argument where an integer was expected.
3326 These functions and methods now raise TypeError instead. The majority of the
3327 effects of this change are in the extension modules, but some core functions
3328 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3329 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00003330

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00003338
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003339- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3340 used to drop the time part of the result.
3341
Georg Brandlba83f822010-03-14 09:50:54 +00003342- Issue #1811: Improve accuracy and cross-platform consistency for true division
3343 of integers: the result of a/b is now correctly rounded for ints a and b (at
3344 least on IEEE 754 platforms), and in particular does not depend on the
3345 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003346
Georg Brandlba83f822010-03-14 09:50:54 +00003347- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3348 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3349 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00003350

Ronald Oussoren92919a62009-12-24 13:30:58 +00003352 executables on OSX.
3353
Georg Brandlba83f822010-03-14 09:50:54 +00003354 These executables now work properly with the arch(1) command: ``arch -ppc
3355 python`` will start a universal binary version of python in PPC mode (unlike
3356 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00003357
Georg Brandlba83f822010-03-14 09:50:54 +00003358- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
3359 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +00003370- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
3371 allowing for a maximum number of tasks within the pool to be completed by the
3372 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00003378- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00003379 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3380 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00003399- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00003400 Initial patch by Brian Curtin.
3401
Georg Brandlba83f822010-03-14 09:50:54 +00003402- Distutils now correctly identifies the build architecture as "x86_64" when
3403 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00003404

Georg Brandlba83f822010-03-14 09:50:54 +00003408- Issue #7552: Removed line feed in the base64 Authorization header in the
3409 Distutils upload command to avoid an error when PyPI reads it. This occurs on
3410 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +00003411

Benjamin Petersonddd392c2009-12-13 19:19:07 +00003415- Issue #7349: Make methods of file objects in the io module accept None as an
3416 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
3417 the same as passing no argument.
3418
Georg Brandlba83f822010-03-14 09:50:54 +00003419- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Mark Dickinsona36507c2010-01-30 10:08:33 +00003440
Georg Brandlba83f822010-03-14 09:50:54 +00003441- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
3442 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3443 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3444 float arguments for integer format codes (other than 'L'): previously an
3445 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3446 TypeError. For the 'L' format code (which previously had no warning) there is
3447 now a DeprecationWarning.

3496 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003497

Georg Brandlba83f822010-03-14 09:50:54 +00003512- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3513 decimal string that's guaranteed to round back to x under correct rounding
3514 (with round-half-to-even rounding mode). Previously it gave a string based on
3515 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3516 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3517 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003518
Georg Brandlba83f822010-03-14 09:50:54 +00003519- Issue #7117: On almost all platforms: float-to-string and string-to-float
3520 conversions within Python are now correctly rounded. Places these conversions
3521 occur include: str for floats and complex numbers; the float and complex
3522 constructors; old-style and new-style numeric formatting; serialization and
3523 deserialization of floats and complex numbers using marshal, pickle and json;
3524 parsing of float and imaginary literals in Python code; Decimal-to-float
3525 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003526
Georg Brandlba83f822010-03-14 09:50:54 +00003527 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3528 providing correctly-rounded strtod and dtoa C functions. This code is
3529 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3530 the C compiler. There may be a small number of platforms on which correct
3531 operation of this code cannot be guaranteed, so the code is not used: notably,
3532 this applies to platforms where the C double format is not IEEE 754 binary64,
3533 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3534 and Python's configure script is unable to determine how to change the FPU
3535 precision. On these platforms conversions use the platform strtod and dtoa,
3536 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003537
Georg Brandlba83f822010-03-14 09:50:54 +00003538- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3539 uses the correctly-rounded string <-> float conversions described above (when
3540 available), and so produces correctly rounded results that will display nicely
3541 under the float repr. There are two related small changes: (1) round now
3542 accepts any class with an ``__index__()`` method for its second argument (but
3543 no longer accepts floats for the second argument), and (2) an excessively
3544 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3545 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003763 untrackable objects are not tracked by the garbage collector. This can reduce
3764 the size of collections and therefore the garbage collection overhead on
3765 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00003771- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
3772 internal representation of integers, for performance reasons. Base 2**30 is
3773 enabled by default on 64-bit machines. Add --enable-big-digits option to
3774 configure, which overrides the default. Add sys.long_info structseq to
3775 provide information about the internal format.

Georg Brandl29c6a282009-04-05 20:23:13 +00003807- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003808 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00003838- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3839 existing .py counterpart, override the co_filename attributes of all code
3840 objects if the original filename is obsolete (which can happen if the file has

3895
Georg Brandlba83f822010-03-14 09:50:54 +00003896- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3897 file objects with closefd=False. The file descriptor is still kept open but
3898 the file object behaves like a closed file. The ``FileIO`` object also got a
3899 new readonly attribute ``closefd``.

3918
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003919- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003922- On windows, ``os.chdir()`` given unicode was not working if
3923 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3924 this code path is really executed because I cannot move to such directory on
3925 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003927- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3928 element is temporarily replaced with an equivalent frozenset. But the
3929 eventual KeyError would always report the empty ``frozenset()`` as the missing
3930 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003950- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3951 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3952 step. This avoids problems with counting UTF-8 bytes that ignores the effect

3954
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003955- Issue #3739: The unicode-internal encoder now reports the number of characters

5127 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5128 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5129 neither __int__ nor __long__, TypeError used to be raised (with a
5130 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5131 struct.error in other cases.

5134 argument with an __int__ method can be packed, but use of this feature
5135 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005328- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5330 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5331 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00005429 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5430 for catch_warnings() also led to an improvement in the raising of a
5431 DeprecationWarning related to warnings.warn_explicit().
5432

5455
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005456- Issue #2975: When compiling several extension modules with Visual Studio 2008
5457 from the same python interpreter, some environment variables would grow
5458 without limit.
5459
Benjamin Peterson37346b22008-08-23 20:27:43 +00005460- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005497What's New in Python 2.6 beta 3?
5498================================
5499
Barry Warsaw07a4a382008-08-21 01:15:08 +00005500*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005501
5502Core and Builtins
5503-----------------
5504
Guido van Rossumf8402962008-08-20 15:01:50 +00005505- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5506 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5507 extensions do not automatically benefit from the class attribute
5508 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5509 to their tp_flags field if they care. This is a backwards
5510 compatibility feature; in 3.0, all types will use the cache by
5511 default.
5512
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005513- Keyword arguments can now follow starred arguments. (``f(a, *args,
5514 keyword=23)`` is now valid syntax.)
5515
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005516- ctypes function pointers that are COM methods have a boolean True
5517 value again.
5518
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005519- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5520 by denying s# to parse objects that have a releasebuffer procedure,
5521 and introducing s*.
5522
Georg Brandl1e13ea92008-08-11 09:07:59 +00005523- Issue #3537: Fix an assertion failure when an empty but presized dict
5524 object was stored in the freelist.
5525
Mark Dickinsonb6467572008-08-04 21:30:09 +00005526- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5527 ValueError consistently across platforms.
5528
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005529- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5530 (64bit Unix, for example), unichr() would truncate its argument and return
5531 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5532
Neal Norwitze7d8be82008-07-31 17:17:14 +00005533- Apply security patches from Apple.
5534
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005535- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5536 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5537
Antoine Pitrou92f82162008-07-25 22:22:08 +00005538- Issue #1819: function calls with several named parameters are now on
5539 average 35% faster (as measured by pybench).
5540
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005541- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5542 the python debugger steps into a class statement: the free variables (local
5543 variables defined in an outer scope) would be deleted from the outer scope.
5544
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005545- Issue #2620: Overflow checking when allocating or reallocating memory
5546 was not always being done properly in some python types and extension
5547 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5548 all been updated to perform better checks and places in the code that
5549 would previously leak memory on the error path when such an allocation
5550 failed have been fixed.
5551

5553-------
5554

5556
Benjamin Petersone977ad42008-08-20 01:42:01 +00005557- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5558 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5559
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005560- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5561 version reported by these tools does not necessarily follow the python
5562 version numbering scheme, so the module is less strict when parsing it.
5563
Nick Coghlanf70385a2008-08-18 12:42:46 +00005564- Issue #2235: Added Py3k warnings for types which will become unhashable
5565 under the stricter __hash__ inheritance rules in 3.0. Several types
5566 which did not meet the rules for hash invariants and were already
5567 unhashable in 3.0 have now been explicitly flagged as unhashable in
5568 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5569 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5570
Brett Cannon88f801d2008-08-18 00:46:22 +00005571- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5579
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005580- Issue #3575: Incremental decoder's decode function now takes bytearray
5581 by using 's*' instead of 't#'.
5582
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005583- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005584 fails unicode conversion on 2nd parameter. (windows only)
5585
Georg Brandl222e2082010-08-01 22:27:39 +00005586- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005587 in a redirect.
5588

Brett Cannon721b1452008-08-16 22:00:27 +00005590 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005591
Facundo Batistaeb90b782008-08-16 14:44:07 +00005592- Issue #2776: fixed small issue when handling an URL with double slash
5593 after a 302 response in the case of not going through a proxy.
5594
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005595- Issue #2676: in the email package, content-type parsing was hanging on
5596 pathological input because of quadratic or exponential behaviour of a
5597 regular expression.
5598
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005599- Issue #3476: binary buffered reading through the new "io" library is now
5600 thread-safe.
5601
Brett Cannonbf3157b2008-08-14 05:00:03 +00005602- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5603 since mimetools itself is deprecated. Because modules are cached, all
5604 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5605
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005606- Issue #3134: shutil referenced undefined WindowsError symbol.
5607
Robert Schuppenies14646332008-08-10 11:01:53 +00005608- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5609 menu entries were not deleted.
5610
Brett Cannon83e81842008-08-09 23:30:55 +00005611- Copied the implementation of reduce() to _functools.reduce() to have a
5612 version that did not raise a DeprecationWarning under -3.
5613
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005614- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5615 a MemoryError rather than silently stop the iteration.
5616
Guido van Rossum59ce9012008-08-09 14:55:34 +00005617- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5618 to _sre.compile() will now be rejected. This should not affect anybody
5619 since the re.compile() function never generates invalid re-bytecode.
5620
Skip Montanaroa032bf42008-08-08 22:52:51 +00005621- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5622 upon first access it can be automatically initialized from the csv file if
5623 it wasn't initialized during instantiation.
5624
Brett Cannon3aa2a492008-08-06 22:28:09 +00005625- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5626 the reload() built-in has been removed.
5627
Brett Cannon7e30b672008-08-04 21:52:25 +00005628- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005629 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005640 asking for a specific length. This problem only affected files opened
5641 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005642

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005691What's New in Python 2.6 beta 2?
5692================================
5693
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005694*Release date: 17-Jul-2008*
5695
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005696Core and Builtins
5697-----------------
5698
Georg Brandl3e483f62008-07-16 22:57:41 +00005699- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5700 its methods now allow for items objects that can be converted to
5701 an integer using operator.index().
5702
Mark Dickinson64b7e502008-07-16 09:40:03 +00005703- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5704 produced a ValueError instead of giving the correct float.
5705
Eric Smitha5fa5a22008-07-16 00:11:49 +00005706- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5707 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5708
Mark Dickinson7103aa42008-07-15 19:08:33 +00005709- Issue #3008: the float type has a new instance method 'float.hex'
5710 and a new class method 'float.fromhex' to convert floating-point
5711 numbers to and from hexadecimal strings, respectively.
5712
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005713- Issue #2235: __hash__ is once again inherited by default. To allow
5714 collections.Hashable to remain meaningful in the presence of the
5715 default hash implementation (object.__hash__), it is now possible
5716 to explicit block inheritance of hash by setting __hash__=None at
5717 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5718 level.
5719
Nick Coghlanb028f502008-07-13 14:52:36 +00005720- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5721 the parent module cannot be found while performing an absolute import.
5722 This means that an incorrectly defined __package__ attribute will
5723 now only prevent relative imports in that module rather than causing
5724 all imports from that module to fail.
5725
Nick Coghlan14ff9942008-07-08 14:21:42 +00005726- Issue #2517: Allow unicode messages in Exceptions again by correctly
5727 bypassing the instance dictionary when looking up __unicode__ on
5728 new-style classes.
5729
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005730- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5731 set to a custom object whose write() method happens to install
5732 another file in sys.stdout.
5733
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005734- Issue #3088: Corrected a race condition in classes derived from
5735 threading.local: the first member set by a thread could be saved in
5736 another thread's dictionary.
5737
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005738- Issue #3004: Minor change to slice.indices(): the start and stop
5739 arguments are now treated identically, making the behaviour easier
5740 to describe and understand. For example, slice(None, -10,
5741 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5742 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5743 10, -1).
5744
Georg Brandl278fc502008-07-19 12:46:12 +00005745- Issue #3219: Calling a function with repeated keyword arguments,
5746 f(a=2, a=23), would not cause a syntax error. This was a regression
5747 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005748
Georg Brandl278fc502008-07-19 12:46:12 +00005749- Issue #2862: Make int and float freelist management consistent with
5750 other freelists. Changes their CompactFreeList apis into
5751 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005752
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005753Library
5754-------
5755
Thomas Heller57adf222008-08-14 19:10:48 +00005756- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5757 api functions without holding the GIL, which could lead to a fatal
5758 error when they failed.
5759
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005760- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5761

5767
Jesse Noller13e9d582008-07-16 14:32:36 +00005768- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5769 ForkingPickler.register() to resolve conflict with ctypes.
5770
Vinay Sajip51e65192008-07-18 09:01:10 +00005771- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005772
Thomas Heller880f5292008-07-15 19:39:38 +00005773- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5774 a valid dlerror() message.
5775
Thomas Heller2bad6572008-07-15 17:19:50 +00005776- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5777 incomplete structure was created.
5778

5780
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005781- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5782
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005783- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005784
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005785- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5786 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005787 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005788 content-length. The problem had been corrected in the 2.4 branch, but never
5789 merged into trunk.
5790
Georg Brandle78fbcc2008-07-05 10:13:36 +00005791- Issue #2663: add filtering capability to shutil.copytree().

5794
5795- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5796
5797- Issue #1746: Correct handling of zipfile archive comments (previously
5798 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005799 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005800
Vinay Sajip51e65192008-07-18 09:01:10 +00005801- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005802 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005803
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005804- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5805 handling is now the same as that of other special attributes like __name__).
5806
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005807- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5808 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006259- Issue #1631171: Re-implement the 'warnings' module in C (the
6260 original Python code has been kept as backup). This will allow for
6261 using the 'warning's machinery in such places as the parser where
6262 use of pure Python code is not possible. Both the ``showarning()``
6263 and ``formatwarning()`` gain an optional 'line' argument which is
6264 not called by default for backwards-compatibility reasons. Setting
6265 ``warnings.showwarning()`` to an implementation that lacks support
6266 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006329- Issue #2550: The approach used by client/server code for obtaining
6330 ports to listen on in network-oriented tests has been refined in an
6331 effort to facilitate running multiple instances of the entire
6332 regression test suite in parallel without issue.
6333 test_support.bind_port() has been fixed such that it will always
6334 return a unique port -- which wasn't always the case with the
6335 previous implementation, especially if socket options had been set
6336 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6337 new implementation of bind_port() will actually raise an exception
6338 if it is passed an AF_INET/SOCK_STREAM socket with either the
6339 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6340 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6341 the socket it's been passed. This currently only applies to
6342 Windows. This option prevents any other sockets from binding to the
6343 host/port we've bound to, thus removing the possibility of the
6344 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6345 when a second SOCK_STREAM socket binds and accepts to a host/port
6346 that's already been bound by another socket. The optional preferred
6347 port parameter to bind_port() has been removed. Under no
6348 circumstances should tests be hard coding ports!
6349
6350 test_support.find_unused_port() has also been introduced, which will
6351 pass a temporary socket object to bind_port() in order to obtain an
6352 unused port. The temporary socket object is then closed and
6353 deleted, and the port is returned. This method should only be used
6354 for obtaining an unused port in order to pass to an external program
6355 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6356 a parameter to a server-oriented class that doesn't give you direct
6357 access to the underlying socket used.
6358
6359 Finally, test_support.HOST has been introduced, which should be used
6360 for the host argument of any relevant socket calls (i.e. bind and
6361 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006362
6363 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006364 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006365 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6366 test_asynchat and test_socket_ssl.
6367
Georg Brandl3ee81df2008-05-17 18:14:43 +00006368 It is now possible for multiple instances of the regression test
6369 suite to run in parallel without issue.

6525 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00006526 platform.machine() and platform.processor() will report this
6527 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00006648- Added the future_builtins module, which contains hex() and oct().
6649 These are the PEP 3127 version of these functions, designed to be
6650 compatible with the hex() and oct() builtins from Python 3.0. They
6651 differ slightly in their output formats from the existing, unchanged
6652 Python 2.6 builtins. The expected usage of the future_builtins
6653 module is:
6654 from future_builtins import hex, oct
6655
Eric Smith7ef40bf2008-02-20 23:34:22 +00006656- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6657 exponents for exponents with absolute value < 100. Follows C99
6658 standard. This is a change on Windows, which would use 3 digits.
6659 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6660 so that any alterations it does to the resulting string will be
6661 available in stringlib/formatter.h (for float.__format__).
6662
Eric Smith5a3c1352008-02-19 13:21:56 +00006663- Implemented PEP 3101, Advanced String Formatting. This adds a new
6664 builtin format(); a format() method for str and unicode; a
6665 __format__() method to object, str, unicode, int, long, float, and
6666 datetime; the class string.Formatter; and the C API
6667 PyObject_Format().
6668
Georg Brandl3ee81df2008-05-17 18:14:43 +00006669- Fixed several potential crashes, all caused by specially crafted
6670 __del__ methods exploiting objects in temporarily inconsistent
6671 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006672
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006673- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006674 prevent a possible crash: an Abstract Base Class would try to access
6675 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006680- Clear all free lists during a gc.collect() of the highest generation
6681 in order to allow pymalloc to free more arenas. Python may give back
6682 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006683
Georg Brandl3ee81df2008-05-17 18:14:43 +00006684- Issue #2045: Fix an infinite recursion triggered when printing a
6685 subclass of collections.defaultdict, if its default_factory is set
6686 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006687
Christian Heimesf75dbef2008-02-08 00:11:31 +00006688- Fixed a minor memory leak in dictobject.c. The content of the free
6689 list was not freed on interpreter shutdown.
6690
Georg Brandl21e99f42010-03-07 15:23:59 +00006691- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006693
Georg Brandl3ee81df2008-05-17 18:14:43 +00006694- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6695 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006696 to compact the internal free lists of pre-allocted ints and floats.
6697
Georg Brandl3ee81df2008-05-17 18:14:43 +00006698- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6699 calls. Python expected the return type int but the fork familie
6700 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006701

Georg Brandl3ee81df2008-05-17 18:14:43 +00006714- Patch #1473257: generator objects gain a gi_code attribute. This is
6715 the same object as the func_code attribute of the function that
6716 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006717
Georg Brandl3ee81df2008-05-17 18:14:43 +00006718- Issue #1920: "while 0" statements were completely removed by the
6719 compiler, even in the presence of an "else" clause, which is
6720 supposed to be run when the condition is false. Now the compiler
6721 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006722
Guido van Rossumeead05f2008-01-24 18:21:02 +00006723- A few crashers fixed: weakref_in_del.py (issue #1377858);
6724 loosing_dict_ref.py (issue #1303614, test67.py);
6725 borrowed_ref_[34].py (not in tracker).
6726

6730
Georg Brandl3ee81df2008-05-17 18:14:43 +00006731- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006732 several extension methods and modules do not work without unicode
6733 support.
6734
Georg Brandl26543b12008-01-21 18:36:51 +00006735- Issue #1882: when compiling code from a string, encoding cookies in the
6736 second line of code were not always recognized correctly.
6737
Georg Brandl14404b62008-01-19 19:27:05 +00006738- Issue #1679: "0x" was taken as a valid integer literal.
6739
Georg Brandl6caad7d2008-01-26 14:19:22 +00006740- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006741 added.
6742
Christian Heimesc94e2b52008-01-14 04:13:37 +00006743- sys.float_info / PyFloat_GetInfo: The floating point information
6744 object was converted from a dict to a specialized structseq object.
6745
Georg Brandl3ee81df2008-05-17 18:14:43 +00006746- Patch #1816: Added sys.flags structseq. It exposes the status of
6747 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006748
Georg Brandl3ee81df2008-05-17 18:14:43 +00006749- Objects/structseq.c: Implemented new structseq representation. The

6760
Georg Brandl3ee81df2008-05-17 18:14:43 +00006761- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6762 envvar and sys.dont_write_bytecode attribute. All these can be set
6763 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006764
Georg Brandl3ee81df2008-05-17 18:14:43 +00006765- Improve some exception messages when Windows fails to load an
6766 extension module. Now we get for example '%1 is not a valid Win32
6767 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006774- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006775 and INF. float("nan"), float("inf") and float("-inf") now work on
6776 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006778- Compiler now generates simpler and faster code for dictionary
6779 literals. The oparg for BUILD_MAP now indicates an estimated
6780 dictionary size. There is a new opcode, STORE_MAP, for adding
6781 entries to the dictionary.

6811 file can now be directly executed by passing their name to the
6812 interpreter. The directory/zipfile is automatically inserted as the
6813 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006815- Issue #1265: Fix a problem with sys.settrace, if the tracing
6816 function uses a generator expression when at the same time the
6817 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006818

6824
Georg Brandl21e99f42010-03-07 15:23:59 +00006825- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006826 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6827 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006828
Georg Brandl3ee81df2008-05-17 18:14:43 +00006829- Issue #1686386: Tuple's tp_repr did not take into account the
6830 possibility of having a self-referential tuple, which is possible
6831 from C code. Nor did object's tp_str consider that a type's tp_str
6832 could do something that could lead to an inifinite recursion.
6833 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6834 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006835
Georg Brandl3ee81df2008-05-17 18:14:43 +00006836- Issue #1164: It was possible to trigger deadlock when using the
6837 'print' statement to write to a file since the GIL was not released
6838 as needed. Now PyObject_Print() does the right thing along with
6839 various tp_print implementations of the built-in types and those in
6840 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00006848
Brett Cannon1e534b52007-09-07 04:18:30 +00006849- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006850 PyObject_Call() never calling back out to Python code to trigger
6851 recursion depth updates/checks. Required the creation of a static
6852 RuntimeError instance in case normalizing an exception put the
6853 recursion check value past its limit. Fixes crashers
6854 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006855

Neal Norwitz0ac60192007-05-27 04:08:54 +00006869- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006870 __*__ attributes. (Some already existed, e.g., __doc__ and
6871 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006872
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006873- Add -3 option to the interpreter to warn about features that are
6874 deprecated and will be changed/removed in Python 3.0.
6875
Georg Brandl2134e752007-05-21 20:34:16 +00006876- Patch #1686487: you can now pass any mapping after '**' in function
6877 calls.
6878
Collin Winter62903052007-05-18 23:11:24 +00006879- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006880 "except E as target:". This is to provide forwards compatibility
6881 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006888- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006889 setting a plain string, ie don't expand to single letter identifiers.
6890
Raymond Hettinger13936692007-04-11 18:40:58 +00006891- Request #1191699: Slices can now be pickled.
6892
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006893- Request #1193128: str.translate() now allows a None argument for
6894 translations that only remove characters without re-mapping the
6895 remaining characters.
6896
Georg Brandl5cb76c12007-03-21 09:00:39 +00006897- Patch #1682205: a TypeError while unpacking an iterable is no longer

6901
Guido van Rossum143b5642007-03-23 04:58:42 +00006902- Bug #1683368: The object.__init__() and object.__new__() methods are
6903 now stricter in rejecting excess arguments. The only time when
6904 either allows excess arguments is when it is not overridden and the
6905 other one is. For backwards compatibility, when both are
6906 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006907 warning later). Also, type.__init__() insists on the same signature
6908 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006909
Georg Brandl3ee81df2008-05-17 18:14:43 +00006910- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6911 object to complex using its __complex__() method before falling back
6912 to the __float__() method. Therefore, the functions in the cmath
6913 module now can operate on objects that define a __complex__()
6914 method.

6918 same slot names.

6925 its type.

6931
Georg Brandl7b9c5552007-03-12 14:30:05 +00006932- Bug #1678647: write a newline after printing an exception in any
6933 case, even when converting the value to a string failed.
6934
Georg Brandl871f1bc2007-03-12 13:17:36 +00006935- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006936 its argument, if it exists. If not, it will work like before. This
6937 allows customizing the output of dir() in the presence of a
6938 __getattr__().

6942
Georg Brandl3ee81df2008-05-17 18:14:43 +00006943- Patch #1675981: remove unreachable code from ``type.__new__()``

6947 parthensized forms. This means complex(repr(x)) now works instead of
6948 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006949
Georg Brandlaa2321b2007-03-07 00:40:28 +00006950- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006951 makes the filenames the warning module prints much more sensible
6952 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006953

Georg Brandl0fca97a2007-03-05 22:28:08 +00006965- Patch #1674228: when assigning a slice (old-style), check for the
6966 sq_ass_slice instead of the sq_slice slot.
6967
Georg Brandl3ee81df2008-05-17 18:14:43 +00006968- When printing an unraisable error, don't print exceptions. before
6969 the name. This duplicates the behavior whening normally printing
6970 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007503 AttributeError instead of an IOError when the server's response
7504 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007505

Georg Brandl3ee81df2008-05-17 18:14:43 +00007521- Patch #1530482: add pydoc.render_doc() which returns the

7536
Georg Brandl92a6bae2007-03-13 17:43:32 +00007537- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007538 are set for invalid interpolation sequences that would lead to
7539 errors on reading back those values.

7595 TestCase and TestSuite subclasses (not instances) are no longer
7596 accepted in TestSuite.addTest(). This should cause no
7597 incompatibility since it never made sense with ordinary subclasses
7598 -- the failure just occurred later, with a more cumbersome
7599 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007988 time so that opening a database previously created with the DB_DUP
7989 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7990 opens. Specifically: dictionary assignment to a DB object will
7991 replace all values for a given key when the database allows
7992 duplicate values. DB users should use DB.put(k, v) when they want
7993 to store duplicates; not DB[k] = v.

8002 behavior of quoting dots if they are the second character of any
8003 line.

8349 of w# format code incorrectly truncated the length to an int, even
8350 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8351 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008381- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8382 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
