1275 In particular, fix extension module build failures when trying to use
1276 32-bit-only installer Pythons on systems with Xcode 4 (currently
1277 OS X 10.8, 10.7, and optionally 10.6).
1278 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1279 * Since Xcode 4 removes ppc support, extension module builds now
1280 check for ppc compiler support and by default remove ppc and
1281 ppc64 archs when they are not available.
1282 * Extension module builds now revert to using system installed
1283 headers and libs (/usr and /System/Library) if the SDK used
1284 to build the interpreter is not installed or has moved.
1285 * Try to avoid building extension modules with deprecated
1286 and problematic Apple llvm-gcc compiler. If original compiler
1287 is not available, use clang instead by default.

1642 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1719 Distutils-based packages with C extension modules may fail because
1720 Apple has removed gcc-4.2, the version used to build python.org
1721 64-bit/32-bit Pythons. If the user does not explicitly override
1722 the default C compiler by setting the CC environment variable,
1723 Distutils will now attempt to compile extension modules with clang
1724 if gcc-4.2 is required but not found. Also as a convenience, if
1725 the user does explicitly set CC, substitute its value as the default
1726 compiler in the Distutils LDSHARED configuration variable for OS X.
1727 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1728 SDK, neither of which are available in Xcode 4. This change does not
1729 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001979- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1980 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1981 interpreter process. This could cause failures in non-Distutils subprocesses
1982 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001983 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001984 deployment target only in the environment of each build subprocess. It is
1985 still possible to globally override the default by setting
1986 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1987 greater or equal to the default value, the value with which the interpreter
1988 was built.

2018 the ticker doesn't have to wind down to zero from the old starting point
2019 before the new interval takes effect. And if the user increases the
2020 interval, it makes sure the new limit takes effect right away rather have an

2991 by Andrew Bennetts.

Raymond Hettinger20397532010-09-12 02:11:45 +00003001- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3002 This prevents user-created self-referencing ordered dictionaries from
3003 becoming permanently uncollectable GC garbage. The downside is that
3004 removing __del__ means that the internal doubly-linked list has to wait for
3005 GC collection rather than freeing memory immediately when the refcnt drops
3006 to zero.
3007
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003008- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3013 would swallow the exception and raise a new one, making it impossible
3014 to fetch the original errno, or to filter timeout errors. Now the
3015 original error is re-raised.
3016
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003017- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

3036
R. David Murray7c4bf552010-08-25 01:45:57 +00003037- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3038 character years even if the message contains RFC822 two character years.
3039

3053
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003054- Issue #9617: Signals received during a low-level write operation aren't
3055 ignored by the buffered IO layer anymore.
3056
Benjamin Peterson52c36052010-08-21 03:03:22 +00003057- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003072- Issue #9550: a BufferedReader could issue an additional read when the
3073 original read request had been satisfied, which could block indefinitely
3074 when the underlying raw IO channel was e.g. a socket. Report and original
3075 patch by Jason V. Miller.
3076
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003077- Issue #9551: Don't raise TypeError when setting the value to None for

3854 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00003866- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3867 with a non-empty format string. This is an effort to future-proof user
3868 code. If a derived class does not currently implement __format__ but later
3869 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003870 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003871 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003921- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3922 InvalidOperation instead of returning False. (Comparisons involving a quiet
3923 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3924 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003925
Georg Brandlfee0f442010-05-22 21:26:21 +00003926- Issue #2531: Comparison operations between floats and Decimal instances now
3927 return a result based on the numeric values of the operands; previously they
3928 returned an arbitrary result based on the relative ordering of id(float) and
3929 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003931- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003932 argument `-` which tells it to read files to compile from stdin. Each line is
3933 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003943- Comparisons using one of <, <=, >, >= between a complex instance and a
3944 Fractions instance now raise TypeError instead of returning True/False. This
3945 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3946 <=> complex, and complex <=> complex comparisons.

4309 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4310 returning NULL. The macro now returns a statically allocated empty string

Georg Brandlba83f822010-03-14 09:50:54 +00004357 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004363- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004364 file position when calling `truncate()`. It would previously change the file
4365 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004366 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4367

4369 class used to represent files stored inside an archive. The new
4370 implementation is significantly faster and can be wrapped in a
4371 ``io.BufferedReader`` object for more speedups. It also solves an issue
4372 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004383- Issue #7748: Since unicode values are supported for some metadata options in
4384 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4385 encoded string for them. This ensures that the upload and register commands
4386 send the correct values to PyPI without any error.

4461-----------------
4462
Georg Brandlba83f822010-03-14 09:50:54 +00004463- The ``__complex__()`` method is now looked up on the class of instances to
4464 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004465
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004466- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4467 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4468
Mark Dickinson1b34d252010-01-01 17:27:30 +00004469- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004470 DeprecationWarning when passed a float argument where an integer was expected.
4471 These functions and methods now raise TypeError instead. The majority of the
4472 effects of this change are in the extension modules, but some core functions
4473 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4474 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00004475

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004484- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4485 used to drop the time part of the result.
4486
Georg Brandlba83f822010-03-14 09:50:54 +00004487- Issue #1811: Improve accuracy and cross-platform consistency for true division
4488 of integers: the result of a/b is now correctly rounded for ints a and b (at
4489 least on IEEE 754 platforms), and in particular does not depend on the
4490 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004491
Georg Brandlba83f822010-03-14 09:50:54 +00004492- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4493 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4494 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004495

Ronald Oussoren92919a62009-12-24 13:30:58 +00004497 executables on OSX.
4498
Georg Brandlba83f822010-03-14 09:50:54 +00004499 These executables now work properly with the arch(1) command: ``arch -ppc
4500 python`` will start a universal binary version of python in PPC mode (unlike
4501 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004502
Georg Brandlba83f822010-03-14 09:50:54 +00004503- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
4504 underlying error when the coercion fails for the left hand operand.

4516 allowing for a maximum number of tasks within the pool to be completed by the
4517 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00004523- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004524 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4525 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00004545 Initial patch by Brian Curtin.
4546
Georg Brandlba83f822010-03-14 09:50:54 +00004547- Distutils now correctly identifies the build architecture as "x86_64" when
4548 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00004549

Benjamin Petersonddd392c2009-12-13 19:19:07 +00004560- Issue #7349: Make methods of file objects in the io module accept None as an
4561 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
4562 the same as passing no argument.
4563
Georg Brandlba83f822010-03-14 09:50:54 +00004564- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00004586- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4587 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4588 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4589 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00004657- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4658 decimal string that's guaranteed to round back to x under correct rounding
4659 (with round-half-to-even rounding mode). Previously it gave a string based on
4660 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4661 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4662 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004663
Georg Brandlba83f822010-03-14 09:50:54 +00004664- Issue #7117: On almost all platforms: float-to-string and string-to-float
4665 conversions within Python are now correctly rounded. Places these conversions
4666 occur include: str for floats and complex numbers; the float and complex
4667 constructors; old-style and new-style numeric formatting; serialization and
4668 deserialization of floats and complex numbers using marshal, pickle and json;
4669 parsing of float and imaginary literals in Python code; Decimal-to-float
4670 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004671
Georg Brandlba83f822010-03-14 09:50:54 +00004672 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4673 providing correctly-rounded strtod and dtoa C functions. This code is
4674 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4675 the C compiler. There may be a small number of platforms on which correct
4676 operation of this code cannot be guaranteed, so the code is not used: notably,
4677 this applies to platforms where the C double format is not IEEE 754 binary64,
4678 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4679 and Python's configure script is unable to determine how to change the FPU
4680 precision. On these platforms conversions use the platform strtod and dtoa,
4681 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004682
Georg Brandlba83f822010-03-14 09:50:54 +00004683- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4684 uses the correctly-rounded string <-> float conversions described above (when
4685 available), and so produces correctly rounded results that will display nicely
4686 under the float repr. There are two related small changes: (1) round now
4687 accepts any class with an ``__index__()`` method for its second argument (but
4688 no longer accepts floats for the second argument), and (2) an excessively
4689 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4690 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004908 untrackable objects are not tracked by the garbage collector. This can reduce
4909 the size of collections and therefore the garbage collection overhead on
4910 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00004916- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
4917 internal representation of integers, for performance reasons. Base 2**30 is
4918 enabled by default on 64-bit machines. Add --enable-big-digits option to
4919 configure, which overrides the default. Add sys.long_info structseq to
4920 provide information about the internal format.

4951
Georg Brandl29c6a282009-04-05 20:23:13 +00004952- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00004953 were suppressing all exceptions. These include list(), filter(), map(),

4955
Benjamin Peterson596d3062009-01-19 15:42:23 +00004956- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00004964- Issue #4935: The overflow checking code in the expandtabs() method common to
4965 str, bytes and bytearray could be optimized away by the compiler, letting the
4966 interpreter segfault instead of raising an error.

4976 collecting the oldest generation) so that allocating lots of objects without
4977 destroying them does not show quadratic performance. Based on a proposal by

4982
Georg Brandlba83f822010-03-14 09:50:54 +00004983- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4984 existing .py counterpart, override the co_filename attributes of all code
4985 objects if the original filename is obsolete (which can happen if the file has
4986 been renamed, moved, or if it is accessed through different paths). Patch by

5027 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5028 instances. On a typical machine this saves 3 bytes of memory (on average) per

5040
Georg Brandlba83f822010-03-14 09:50:54 +00005041- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5042 file objects with closefd=False. The file descriptor is still kept open but
5043 the file object behaves like a closed file. The ``FileIO`` object also got a
5044 new readonly attribute ``closefd``.

5063
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005064- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005067- On windows, ``os.chdir()`` given unicode was not working if
5068 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5069 this code path is really executed because I cannot move to such directory on
5070 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005072- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5073 element is temporarily replaced with an equivalent frozenset. But the
5074 eventual KeyError would always report the empty ``frozenset()`` as the missing
5075 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005095- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5096 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5097 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5098 of using the replace error handler in PyUnicode_DecodeUTF8().
5099
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005100- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005103- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5105 gives improved memory leak detection when running under Valgrind, while taking
5106 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006273 - If x is not an int, long or float, then packing x will always result in
6274 struct.error. Previously an x with an __int__ method could be packed by
6275 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6276 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6277 neither __int__ nor __long__, TypeError used to be raised (with a
6278 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6279 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00006281 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
6282 argument with an __int__ method can be packed, but use of this feature
6283 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006476- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6478 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Brett Cannon1eaf0742008-09-02 01:25:16 +00006577 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6578 for catch_warnings() also led to an improvement in the raising of a
6579 DeprecationWarning related to warnings.warn_explicit().
6580

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006645What's New in Python 2.6 beta 3?
6646================================
6647
Barry Warsaw07a4a382008-08-21 01:15:08 +00006648*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006649
6650Core and Builtins
6651-----------------
6652
Guido van Rossumf8402962008-08-20 15:01:50 +00006653- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6654 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6655 extensions do not automatically benefit from the class attribute
6656 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6657 to their tp_flags field if they care. This is a backwards
6658 compatibility feature; in 3.0, all types will use the cache by
6659 default.
6660
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006661- Keyword arguments can now follow starred arguments. (``f(a, *args,
6662 keyword=23)`` is now valid syntax.)
6663
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006664- ctypes function pointers that are COM methods have a boolean True
6665 value again.
6666
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006667- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6668 by denying s# to parse objects that have a releasebuffer procedure,
6669 and introducing s*.
6670
Georg Brandl1e13ea92008-08-11 09:07:59 +00006671- Issue #3537: Fix an assertion failure when an empty but presized dict
6672 object was stored in the freelist.
6673
Mark Dickinsonb6467572008-08-04 21:30:09 +00006674- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6675 ValueError consistently across platforms.
6676
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006677- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6678 (64bit Unix, for example), unichr() would truncate its argument and return
6679 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6680
Neal Norwitze7d8be82008-07-31 17:17:14 +00006681- Apply security patches from Apple.
6682
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006683- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6684 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6685
Antoine Pitrou92f82162008-07-25 22:22:08 +00006686- Issue #1819: function calls with several named parameters are now on
6687 average 35% faster (as measured by pybench).
6688
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006689- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6690 the python debugger steps into a class statement: the free variables (local
6691 variables defined in an outer scope) would be deleted from the outer scope.
6692
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006693- Issue #2620: Overflow checking when allocating or reallocating memory
6694 was not always being done properly in some python types and extension
6695 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6696 all been updated to perform better checks and places in the code that
6697 would previously leak memory on the error path when such an allocation
6698 failed have been fixed.

6704
Benjamin Petersone977ad42008-08-20 01:42:01 +00006705- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6706 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6707
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006708- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6709 version reported by these tools does not necessarily follow the python
6710 version numbering scheme, so the module is less strict when parsing it.
6711
Nick Coghlanf70385a2008-08-18 12:42:46 +00006712- Issue #2235: Added Py3k warnings for types which will become unhashable
6713 under the stricter __hash__ inheritance rules in 3.0. Several types
6714 which did not meet the rules for hash invariants and were already
6715 unhashable in 3.0 have now been explicitly flagged as unhashable in
6716 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6717 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6718
Brett Cannon88f801d2008-08-18 00:46:22 +00006719- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6727
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006728- Issue #3575: Incremental decoder's decode function now takes bytearray
6729 by using 's*' instead of 't#'.
6730
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006731- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006732 fails unicode conversion on 2nd parameter. (windows only)
6733
Georg Brandl222e2082010-08-01 22:27:39 +00006734- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006735 in a redirect.
6736

Brett Cannon721b1452008-08-16 22:00:27 +00006738 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006739
Facundo Batistaeb90b782008-08-16 14:44:07 +00006740- Issue #2776: fixed small issue when handling an URL with double slash
6741 after a 302 response in the case of not going through a proxy.
6742
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006743- Issue #2676: in the email package, content-type parsing was hanging on
6744 pathological input because of quadratic or exponential behaviour of a
6745 regular expression.
6746
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006747- Issue #3476: binary buffered reading through the new "io" library is now
6748 thread-safe.
6749
Brett Cannonbf3157b2008-08-14 05:00:03 +00006750- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6751 since mimetools itself is deprecated. Because modules are cached, all
6752 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6753
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006754- Issue #3134: shutil referenced undefined WindowsError symbol.
6755
Robert Schuppenies14646332008-08-10 11:01:53 +00006756- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6757 menu entries were not deleted.
6758
Brett Cannon83e81842008-08-09 23:30:55 +00006759- Copied the implementation of reduce() to _functools.reduce() to have a
6760 version that did not raise a DeprecationWarning under -3.
6761
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006762- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6763 a MemoryError rather than silently stop the iteration.
6764
Guido van Rossum59ce9012008-08-09 14:55:34 +00006765- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6766 to _sre.compile() will now be rejected. This should not affect anybody
6767 since the re.compile() function never generates invalid re-bytecode.
6768
Skip Montanaroa032bf42008-08-08 22:52:51 +00006769- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6770 upon first access it can be automatically initialized from the csv file if
6771 it wasn't initialized during instantiation.
6772
Brett Cannon3aa2a492008-08-06 22:28:09 +00006773- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6774 the reload() built-in has been removed.
6775
Brett Cannon7e30b672008-08-04 21:52:25 +00006776- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006777 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006788 asking for a specific length. This problem only affected files opened
6789 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006790

6831 interaction with the tp_hash slot (added in 2.6b2) are now documented
6832
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006833- Issue #643841: The language reference now provides more detailed
6834 coverage of the lookup process for special methods. The disclaimers
6835 regarding lack of coverage of new-style classes have also been
6836 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006839What's New in Python 2.6 beta 2?
6840================================
6841
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006842*Release date: 17-Jul-2008*
6843
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006844Core and Builtins
6845-----------------
6846
Georg Brandl3e483f62008-07-16 22:57:41 +00006847- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6848 its methods now allow for items objects that can be converted to
6849 an integer using operator.index().
6850
Mark Dickinson64b7e502008-07-16 09:40:03 +00006851- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6852 produced a ValueError instead of giving the correct float.
6853
Eric Smitha5fa5a22008-07-16 00:11:49 +00006854- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6855 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6856
Mark Dickinson7103aa42008-07-15 19:08:33 +00006857- Issue #3008: the float type has a new instance method 'float.hex'
6858 and a new class method 'float.fromhex' to convert floating-point
6859 numbers to and from hexadecimal strings, respectively.
6860
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006861- Issue #2235: __hash__ is once again inherited by default. To allow
6862 collections.Hashable to remain meaningful in the presence of the
6863 default hash implementation (object.__hash__), it is now possible
6864 to explicit block inheritance of hash by setting __hash__=None at
6865 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6866 level.
6867
Nick Coghlanb028f502008-07-13 14:52:36 +00006868- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6869 the parent module cannot be found while performing an absolute import.
6870 This means that an incorrectly defined __package__ attribute will
6871 now only prevent relative imports in that module rather than causing
6872 all imports from that module to fail.
6873
Nick Coghlan14ff9942008-07-08 14:21:42 +00006874- Issue #2517: Allow unicode messages in Exceptions again by correctly
6875 bypassing the instance dictionary when looking up __unicode__ on
6876 new-style classes.
6877
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006878- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6879 set to a custom object whose write() method happens to install
6880 another file in sys.stdout.
6881
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006882- Issue #3088: Corrected a race condition in classes derived from
6883 threading.local: the first member set by a thread could be saved in
6884 another thread's dictionary.
6885
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006886- Issue #3004: Minor change to slice.indices(): the start and stop
6887 arguments are now treated identically, making the behaviour easier
6888 to describe and understand. For example, slice(None, -10,
6889 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6890 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6891 10, -1).
6892
Georg Brandl278fc502008-07-19 12:46:12 +00006893- Issue #3219: Calling a function with repeated keyword arguments,
6894 f(a=2, a=23), would not cause a syntax error. This was a regression
6895 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006896
Georg Brandl278fc502008-07-19 12:46:12 +00006897- Issue #2862: Make int and float freelist management consistent with
6898 other freelists. Changes their CompactFreeList apis into
6899 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006900

6902-------
6903
Thomas Heller57adf222008-08-14 19:10:48 +00006904- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6905 api functions without holding the GIL, which could lead to a fatal
6906 error when they failed.
6907
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006908- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006916- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6917 ForkingPickler.register() to resolve conflict with ctypes.
6918
Vinay Sajip51e65192008-07-18 09:01:10 +00006919- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006920
Thomas Heller880f5292008-07-15 19:39:38 +00006921- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6922 a valid dlerror() message.
6923
Thomas Heller2bad6572008-07-15 17:19:50 +00006924- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6925 incomplete structure was created.
6926
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006927- Issue #3339: dummy_thread.acquire() should not return None.
6928
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006929- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6930
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006931- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006932
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006933- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6934 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006935 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006936 content-length. The problem had been corrected in the 2.4 branch, but never
6937 merged into trunk.
6938
Georg Brandle78fbcc2008-07-05 10:13:36 +00006939- Issue #2663: add filtering capability to shutil.copytree().
6940

6944
6945- Issue #1746: Correct handling of zipfile archive comments (previously
6946 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006947 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006948
Vinay Sajip51e65192008-07-18 09:01:10 +00006949- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006950 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006951
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006952- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6953 handling is now the same as that of other special attributes like __name__).
6954
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006955- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6956 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007407- Issue #1631171: Re-implement the 'warnings' module in C (the
7408 original Python code has been kept as backup). This will allow for
7409 using the 'warning's machinery in such places as the parser where
7410 use of pure Python code is not possible. Both the ``showarning()``
7411 and ``formatwarning()`` gain an optional 'line' argument which is
7412 not called by default for backwards-compatibility reasons. Setting
7413 ``warnings.showwarning()`` to an implementation that lacks support
7414 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007477- Issue #2550: The approach used by client/server code for obtaining
7478 ports to listen on in network-oriented tests has been refined in an
7479 effort to facilitate running multiple instances of the entire
7480 regression test suite in parallel without issue.
7481 test_support.bind_port() has been fixed such that it will always
7482 return a unique port -- which wasn't always the case with the
7483 previous implementation, especially if socket options had been set
7484 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7485 new implementation of bind_port() will actually raise an exception
7486 if it is passed an AF_INET/SOCK_STREAM socket with either the
7487 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7488 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7489 the socket it's been passed. This currently only applies to
7490 Windows. This option prevents any other sockets from binding to the
7491 host/port we've bound to, thus removing the possibility of the
7492 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7493 when a second SOCK_STREAM socket binds and accepts to a host/port
7494 that's already been bound by another socket. The optional preferred
7495 port parameter to bind_port() has been removed. Under no
7496 circumstances should tests be hard coding ports!
7497
7498 test_support.find_unused_port() has also been introduced, which will
7499 pass a temporary socket object to bind_port() in order to obtain an
7500 unused port. The temporary socket object is then closed and
7501 deleted, and the port is returned. This method should only be used
7502 for obtaining an unused port in order to pass to an external program
7503 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7504 a parameter to a server-oriented class that doesn't give you direct
7505 access to the underlying socket used.
7506
7507 Finally, test_support.HOST has been introduced, which should be used
7508 for the host argument of any relevant socket calls (i.e. bind and
7509 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007510
7511 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007512 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007513 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7514 test_asynchat and test_socket_ssl.
7515
Georg Brandl3ee81df2008-05-17 18:14:43 +00007516 It is now possible for multiple instances of the regression test
7517 suite to run in parallel without issue.

Facundo Batistafc2d0102008-02-23 12:01:13 +00007795
Eric Smitha73fbe72008-02-23 03:09:44 +00007796- Added the future_builtins module, which contains hex() and oct().
7797 These are the PEP 3127 version of these functions, designed to be
7798 compatible with the hex() and oct() builtins from Python 3.0. They
7799 differ slightly in their output formats from the existing, unchanged
7800 Python 2.6 builtins. The expected usage of the future_builtins
7801 module is:
7802 from future_builtins import hex, oct
7803
Eric Smith7ef40bf2008-02-20 23:34:22 +00007804- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7805 exponents for exponents with absolute value < 100. Follows C99
7806 standard. This is a change on Windows, which would use 3 digits.
7807 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7808 so that any alterations it does to the resulting string will be
7809 available in stringlib/formatter.h (for float.__format__).
7810
Eric Smith5a3c1352008-02-19 13:21:56 +00007811- Implemented PEP 3101, Advanced String Formatting. This adds a new
7812 builtin format(); a format() method for str and unicode; a
7813 __format__() method to object, str, unicode, int, long, float, and
7814 datetime; the class string.Formatter; and the C API
7815 PyObject_Format().
7816
Georg Brandl3ee81df2008-05-17 18:14:43 +00007817- Fixed several potential crashes, all caused by specially crafted
7818 __del__ methods exploiting objects in temporarily inconsistent
7819 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007820
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007821- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007822 prevent a possible crash: an Abstract Base Class would try to access
7823 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007824
Georg Brandl3ee81df2008-05-17 18:14:43 +00007825- Fixed repr() and str() of complex numbers with infinity or nan as
7826 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007828- Clear all free lists during a gc.collect() of the highest generation
7829 in order to allow pymalloc to free more arenas. Python may give back
7830 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007831
Georg Brandl3ee81df2008-05-17 18:14:43 +00007832- Issue #2045: Fix an infinite recursion triggered when printing a
7833 subclass of collections.defaultdict, if its default_factory is set
7834 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007835
Christian Heimesf75dbef2008-02-08 00:11:31 +00007836- Fixed a minor memory leak in dictobject.c. The content of the free
7837 list was not freed on interpreter shutdown.
7838
Georg Brandl21e99f42010-03-07 15:23:59 +00007839- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007840 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007841
Georg Brandl3ee81df2008-05-17 18:14:43 +00007842- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7843 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007844 to compact the internal free lists of pre-allocted ints and floats.
7845
Georg Brandl3ee81df2008-05-17 18:14:43 +00007846- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7847 calls. Python expected the return type int but the fork familie
7848 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007849
Georg Brandl3ee81df2008-05-17 18:14:43 +00007850- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7851 appear in the same code unit.

7860 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007861
Georg Brandl3ee81df2008-05-17 18:14:43 +00007862- Patch #1473257: generator objects gain a gi_code attribute. This is
7863 the same object as the func_code attribute of the function that
7864 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007865
Georg Brandl3ee81df2008-05-17 18:14:43 +00007866- Issue #1920: "while 0" statements were completely removed by the
7867 compiler, even in the presence of an "else" clause, which is
7868 supposed to be run when the condition is false. Now the compiler
7869 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007870
Guido van Rossumeead05f2008-01-24 18:21:02 +00007871- A few crashers fixed: weakref_in_del.py (issue #1377858);
7872 loosing_dict_ref.py (issue #1303614, test67.py);
7873 borrowed_ref_[34].py (not in tracker).

7878
Georg Brandl3ee81df2008-05-17 18:14:43 +00007879- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007880 several extension methods and modules do not work without unicode
7881 support.
7882
Georg Brandl26543b12008-01-21 18:36:51 +00007883- Issue #1882: when compiling code from a string, encoding cookies in the

7885
Georg Brandl14404b62008-01-19 19:27:05 +00007886- Issue #1679: "0x" was taken as a valid integer literal.
7887
Georg Brandl6caad7d2008-01-26 14:19:22 +00007888- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007889 added.
7890
Christian Heimesc94e2b52008-01-14 04:13:37 +00007891- sys.float_info / PyFloat_GetInfo: The floating point information
7892 object was converted from a dict to a specialized structseq object.
7893
Georg Brandl3ee81df2008-05-17 18:14:43 +00007894- Patch #1816: Added sys.flags structseq. It exposes the status of
7895 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007896
Georg Brandl3ee81df2008-05-17 18:14:43 +00007897- Objects/structseq.c: Implemented new structseq representation. The
7898 patch makes structseqs (e.g. the return value of os.stat) more
7899 readable.

Georg Brandlaed6c662008-01-07 17:25:53 +00007907- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7908
Georg Brandl3ee81df2008-05-17 18:14:43 +00007909- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7910 envvar and sys.dont_write_bytecode attribute. All these can be set
7911 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007912
Georg Brandl3ee81df2008-05-17 18:14:43 +00007913- Improve some exception messages when Windows fails to load an
7914 extension module. Now we get for example '%1 is not a valid Win32
7915 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007922- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007923 and INF. float("nan"), float("inf") and float("-inf") now work on
7924 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007926- Compiler now generates simpler and faster code for dictionary
7927 literals. The oparg for BUILD_MAP now indicates an estimated
7928 dictionary size. There is a new opcode, STORE_MAP, for adding
7929 entries to the dictionary.

7959 file can now be directly executed by passing their name to the
7960 interpreter. The directory/zipfile is automatically inserted as the
7961 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007963- Issue #1265: Fix a problem with sys.settrace, if the tracing
7964 function uses a generator expression when at the same time the
7965 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007966
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007967- sets and frozensets now have an isdisjoint() method.

7972
Georg Brandl21e99f42010-03-07 15:23:59 +00007973- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007974 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7975 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007976
Georg Brandl3ee81df2008-05-17 18:14:43 +00007977- Issue #1686386: Tuple's tp_repr did not take into account the
7978 possibility of having a self-referential tuple, which is possible
7979 from C code. Nor did object's tp_str consider that a type's tp_str
7980 could do something that could lead to an inifinite recursion.
7981 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7982 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007983
Georg Brandl3ee81df2008-05-17 18:14:43 +00007984- Issue #1164: It was possible to trigger deadlock when using the
7985 'print' statement to write to a file since the GIL was not released
7986 as needed. Now PyObject_Print() does the right thing along with
7987 various tp_print implementations of the built-in types and those in
7988 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00007996
Brett Cannon1e534b52007-09-07 04:18:30 +00007997- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998 PyObject_Call() never calling back out to Python code to trigger
7999 recursion depth updates/checks. Required the creation of a static
8000 RuntimeError instance in case normalizing an exception put the
8001 recursion check value past its limit. Fixes crashers
8002 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008003

Neal Norwitz0ac60192007-05-27 04:08:54 +00008017- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008018 __*__ attributes. (Some already existed, e.g., __doc__ and
8019 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008020
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008021- Add -3 option to the interpreter to warn about features that are
8022 deprecated and will be changed/removed in Python 3.0.
8023
Georg Brandl2134e752007-05-21 20:34:16 +00008024- Patch #1686487: you can now pass any mapping after '**' in function
8025 calls.
8026
Collin Winter62903052007-05-18 23:11:24 +00008027- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008028 "except E as target:". This is to provide forwards compatibility
8029 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008036- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008037 setting a plain string, ie don't expand to single letter identifiers.
8038
Raymond Hettinger13936692007-04-11 18:40:58 +00008039- Request #1191699: Slices can now be pickled.
8040
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008041- Request #1193128: str.translate() now allows a None argument for
8042 translations that only remove characters without re-mapping the
8043 remaining characters.
8044
Georg Brandl5cb76c12007-03-21 09:00:39 +00008045- Patch #1682205: a TypeError while unpacking an iterable is no longer

8049
Guido van Rossum143b5642007-03-23 04:58:42 +00008050- Bug #1683368: The object.__init__() and object.__new__() methods are
8051 now stricter in rejecting excess arguments. The only time when
8052 either allows excess arguments is when it is not overridden and the
8053 other one is. For backwards compatibility, when both are
8054 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008055 warning later). Also, type.__init__() insists on the same signature
8056 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8059 object to complex using its __complex__() method before falling back
8060 to the __float__() method. Therefore, the functions in the cmath
8061 module now can operate on objects that define a __complex__()
8062 method.

8079
Georg Brandl7b9c5552007-03-12 14:30:05 +00008080- Bug #1678647: write a newline after printing an exception in any
8081 case, even when converting the value to a string failed.
8082
Georg Brandl871f1bc2007-03-12 13:17:36 +00008083- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008084 its argument, if it exists. If not, it will work like before. This
8085 allows customizing the output of dir() in the presence of a
8086 __getattr__().

8095 parthensized forms. This means complex(repr(x)) now works instead of
8096 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008097
Georg Brandlaa2321b2007-03-07 00:40:28 +00008098- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099 makes the filenames the warning module prints much more sensible
8100 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008113- Patch #1674228: when assigning a slice (old-style), check for the
8114 sq_ass_slice instead of the sq_slice slot.
8115
Georg Brandl3ee81df2008-05-17 18:14:43 +00008116- When printing an unraisable error, don't print exceptions. before
8117 the name. This duplicates the behavior whening normally printing
8118 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008651 AttributeError instead of an IOError when the server's response
8652 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008653

8668
Georg Brandl3ee81df2008-05-17 18:14:43 +00008669- Patch #1530482: add pydoc.render_doc() which returns the

8684
Georg Brandl92a6bae2007-03-13 17:43:32 +00008685- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008686 are set for invalid interpolation sequences that would lead to
8687 errors on reading back those values.

8728

8730 returned string up to the first NUL character.

8741
Georg Brandl3ee81df2008-05-17 18:14:43 +00008742- unittest now verifies more of its assumptions. In particular,
8743 TestCase and TestSuite subclasses (not instances) are no longer
8744 accepted in TestSuite.addTest(). This should cause no
8745 incompatibility since it never made sense with ordinary subclasses
8746 -- the failure just occurred later, with a more cumbersome
8747 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009111- Marshal.dumps() now expects exact type matches for int, long, float,
9112 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9113 silently miscode subclasses of those types. Now, it raises a
9114 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009129- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009130 time so that opening a database previously created with the DB_DUP
9131 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9132 opens. Specifically: dictionary assignment to a DB object will
9133 replace all values for a given key when the database allows
9134 duplicate values. DB users should use DB.put(k, v) when they want
9135 to store duplicates; not DB[k] = v.

9144 behavior of quoting dots if they are the second character of any
9145 line.

9500 of w# format code incorrectly truncated the length to an int, even
9501 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9502 incorrect results with huge strings.
