39 longer include a "manifest" to prevent them failing at import time in some
40 embedded situations.

Mark Dickinsondbbed042011-09-19 16:38:08 +010051- Issue #12973: Fix overflow checks that invoked undefined behaviour in
52 int.__pow__. These overflow checks were causing int.__pow__ to produce
53 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010054 compiler optimizing the check away. Also fix similar overflow checks
55 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
56 bugs caused test failures with recent versions of Clang.

68 cleared by the garbage collector. This fixes a segfault when an instance
69 and its type get caught in a reference cycle, and the instance's
70 deallocator calls one of the methods on the type (e.g. when subclassing

81 raw_input() interrupted by CTRL+c.
82
Łukasz Langa7a153902011-10-18 17:16:00 +020083- Issue #10860: httplib now correctly handles an empty port after port
84 delimiter in URLs.

Ned Deily87e82bb2011-06-28 19:52:59 -0700326- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
327 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
328 interpreter process. This could cause failures in non-Distutils subprocesses
329 and was unreliable since tests or user programs could modify the interpreter
330 environment after Distutils set it. Instead, have Distutils set the the
331 deployment target only in the environment of each build subprocess. It is
332 still possible to globally override the default by setting
333 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
334 greater or equal to the default value, the value with which the interpreter
335 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001282- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1283 This prevents user-created self-referencing ordered dictionaries from
1284 becoming permanently uncollectable GC garbage. The downside is that
1285 removing __del__ means that the internal doubly-linked list has to wait for
1286 GC collection rather than freeing memory immediately when the refcnt drops
1287 to zero.
1288

1294 would swallow the exception and raise a new one, making it impossible
1295 to fetch the original errno, or to filter timeout errors. Now the
1296 original error is re-raised.

1317
R. David Murray7c4bf552010-08-25 01:45:57 +00001318- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1319 character years even if the message contains RFC822 two character years.

1337
Benjamin Peterson52c36052010-08-21 03:03:22 +00001338- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001353- Issue #9550: a BufferedReader could issue an additional read when the
1354 original read request had been satisfied, which could block indefinitely
1355 when the underlying raw IO channel was e.g. a socket. Report and original
1356 patch by Jason V. Miller.
1357
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001358- Issue #9551: Don't raise TypeError when setting the value to None for

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002132- Issue #7301: Add environment variable $PYTHONWARNINGS.
2133
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002134- Issue #8329: Don't return the same lists from select.select when no fds are
2135 changed.
2136
Georg Brandlfee0f442010-05-22 21:26:21 +00002137- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00002147- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2148 with a non-empty format string. This is an effort to future-proof user
2149 code. If a derived class does not currently implement __format__ but later
2150 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002151 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002152 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002185- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00002202- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2203 InvalidOperation instead of returning False. (Comparisons involving a quiet
2204 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2205 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002206
Georg Brandlfee0f442010-05-22 21:26:21 +00002207- Issue #2531: Comparison operations between floats and Decimal instances now
2208 return a result based on the numeric values of the operands; previously they
2209 returned an arbitrary result based on the relative ordering of id(float) and
2210 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002211
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002212- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002213 argument `-` which tells it to read files to compile from stdin. Each line is
2214 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00002224- Comparisons using one of <, <=, >, >= between a complex instance and a
2225 Fractions instance now raise TypeError instead of returning True/False. This
2226 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2227 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002584- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2585 and add the additional members returned in an OSVERSIONINFOEX structure. The
2586 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002589- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2590 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2591 returning NULL. The macro now returns a statically allocated empty string
2592 instead.

2602 strings,
2603 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2604 numeric strings corresponding to subnormal values,
2605 (3) a memory leak for some values large enough to cause overflow, and
2606 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002637- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002638 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002639 Also, raise ValueError rather than TypeError when an unknown TIPC address
2640 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002644- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002645 file position when calling `truncate()`. It would previously change the file
2646 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002647 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2648
Georg Brandlba83f822010-03-14 09:50:54 +00002649- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2650 class used to represent files stored inside an archive. The new
2651 implementation is significantly faster and can be wrapped in a
2652 ``io.BufferedReader`` object for more speedups. It also solves an issue
2653 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002664- Issue #7748: Since unicode values are supported for some metadata options in
2665 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2666 encoded string for them. This ensures that the upload and register commands
2667 send the correct values to PyPI without any error.

2742-----------------
2743
Georg Brandlba83f822010-03-14 09:50:54 +00002744- The ``__complex__()`` method is now looked up on the class of instances to
2745 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002746
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002747- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2748 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2749
Mark Dickinson1b34d252010-01-01 17:27:30 +00002750- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002751 DeprecationWarning when passed a float argument where an integer was expected.
2752 These functions and methods now raise TypeError instead. The majority of the
2753 effects of this change are in the extension modules, but some core functions
2754 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2755 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002756

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002765- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2766 used to drop the time part of the result.
2767
Georg Brandlba83f822010-03-14 09:50:54 +00002768- Issue #1811: Improve accuracy and cross-platform consistency for true division
2769 of integers: the result of a/b is now correctly rounded for ints a and b (at
2770 least on IEEE 754 platforms), and in particular does not depend on the
2771 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002772
Georg Brandlba83f822010-03-14 09:50:54 +00002773- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2774 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2775 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002776

Ronald Oussoren92919a62009-12-24 13:30:58 +00002778 executables on OSX.
2779
Georg Brandlba83f822010-03-14 09:50:54 +00002780 These executables now work properly with the arch(1) command: ``arch -ppc
2781 python`` will start a universal binary version of python in PPC mode (unlike
2782 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002783
Georg Brandlba83f822010-03-14 09:50:54 +00002784- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2785 underlying error when the coercion fails for the left hand operand.

2797 allowing for a maximum number of tasks within the pool to be completed by the
2798 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00002804- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002805 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2806 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00002826 Initial patch by Brian Curtin.
2827
Georg Brandlba83f822010-03-14 09:50:54 +00002828- Distutils now correctly identifies the build architecture as "x86_64" when
2829 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00002830

2835 Distutils upload command to avoid an error when PyPI reads it. This occurs on
2836 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +00002837

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002841- Issue #7349: Make methods of file objects in the io module accept None as an
2842 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2843 the same as passing no argument.
2844
Georg Brandlba83f822010-03-14 09:50:54 +00002845- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00002867- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2868 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2869 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2870 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00002938- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2939 decimal string that's guaranteed to round back to x under correct rounding
2940 (with round-half-to-even rounding mode). Previously it gave a string based on
2941 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2942 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2943 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002944
Georg Brandlba83f822010-03-14 09:50:54 +00002945- Issue #7117: On almost all platforms: float-to-string and string-to-float
2946 conversions within Python are now correctly rounded. Places these conversions
2947 occur include: str for floats and complex numbers; the float and complex
2948 constructors; old-style and new-style numeric formatting; serialization and
2949 deserialization of floats and complex numbers using marshal, pickle and json;
2950 parsing of float and imaginary literals in Python code; Decimal-to-float
2951 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002952
Georg Brandlba83f822010-03-14 09:50:54 +00002953 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2954 providing correctly-rounded strtod and dtoa C functions. This code is
2955 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2956 the C compiler. There may be a small number of platforms on which correct
2957 operation of this code cannot be guaranteed, so the code is not used: notably,
2958 this applies to platforms where the C double format is not IEEE 754 binary64,
2959 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2960 and Python's configure script is unable to determine how to change the FPU
2961 precision. On these platforms conversions use the platform strtod and dtoa,
2962 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002963
Georg Brandlba83f822010-03-14 09:50:54 +00002964- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2965 uses the correctly-rounded string <-> float conversions described above (when
2966 available), and so produces correctly rounded results that will display nicely
2967 under the float repr. There are two related small changes: (1) round now
2968 accepts any class with an ``__index__()`` method for its second argument (but
2969 no longer accepts floats for the second argument), and (2) an excessively
2970 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2971 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003189 untrackable objects are not tracked by the garbage collector. This can reduce
3190 the size of collections and therefore the garbage collection overhead on
3191 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00003197- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
3198 internal representation of integers, for performance reasons. Base 2**30 is
3199 enabled by default on 64-bit machines. Add --enable-big-digits option to
3200 configure, which overrides the default. Add sys.long_info structseq to
3201 provide information about the internal format.

3232
Georg Brandl29c6a282009-04-05 20:23:13 +00003233- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003234 were suppressing all exceptions. These include list(), filter(), map(),

3236
Benjamin Peterson596d3062009-01-19 15:42:23 +00003237- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00003245- Issue #4935: The overflow checking code in the expandtabs() method common to
3246 str, bytes and bytearray could be optimized away by the compiler, letting the
3247 interpreter segfault instead of raising an error.

3257 collecting the oldest generation) so that allocating lots of objects without
3258 destroying them does not show quadratic performance. Based on a proposal by

3263
Georg Brandlba83f822010-03-14 09:50:54 +00003264- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3265 existing .py counterpart, override the co_filename attributes of all code
3266 objects if the original filename is obsolete (which can happen if the file has
3267 been renamed, moved, or if it is accessed through different paths). Patch by

3308 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3309 instances. On a typical machine this saves 3 bytes of memory (on average) per

3321
Georg Brandlba83f822010-03-14 09:50:54 +00003322- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3323 file objects with closefd=False. The file descriptor is still kept open but
3324 the file object behaves like a closed file. The ``FileIO`` object also got a
3325 new readonly attribute ``closefd``.

3344
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003345- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003346 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003348- On windows, ``os.chdir()`` given unicode was not working if
3349 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3350 this code path is really executed because I cannot move to such directory on
3351 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003353- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3354 element is temporarily replaced with an equivalent frozenset. But the
3355 eventual KeyError would always report the empty ``frozenset()`` as the missing
3356 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003376- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3377 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3378 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3379 of using the replace error handler in PyUnicode_DecodeUTF8().
3380
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003381- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003384- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3386 gives improved memory leak detection when running under Valgrind, while taking
3387 advantage of pymalloc at other times.

4553 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4554 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4555 neither __int__ nor __long__, TypeError used to be raised (with a
4556 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4557 struct.error in other cases.

4560 argument with an __int__ method can be packed, but use of this feature
4561 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004754- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4756 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4757 ``printf`` function, whereas PyString_FromFormat has an independent
4758 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004855 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4856 for catch_warnings() also led to an improvement in the raising of a
4857 DeprecationWarning related to warnings.warn_explicit().
4858

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004923What's New in Python 2.6 beta 3?
4924================================
4925
Barry Warsaw07a4a382008-08-21 01:15:08 +00004926*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004927
4928Core and Builtins
4929-----------------
4930
Guido van Rossumf8402962008-08-20 15:01:50 +00004931- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4932 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4933 extensions do not automatically benefit from the class attribute
4934 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4935 to their tp_flags field if they care. This is a backwards
4936 compatibility feature; in 3.0, all types will use the cache by
4937 default.
4938
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004939- Keyword arguments can now follow starred arguments. (``f(a, *args,
4940 keyword=23)`` is now valid syntax.)
4941
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004942- ctypes function pointers that are COM methods have a boolean True
4943 value again.
4944
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004945- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4946 by denying s# to parse objects that have a releasebuffer procedure,
4947 and introducing s*.
4948
Georg Brandl1e13ea92008-08-11 09:07:59 +00004949- Issue #3537: Fix an assertion failure when an empty but presized dict
4950 object was stored in the freelist.
4951
Mark Dickinsonb6467572008-08-04 21:30:09 +00004952- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4953 ValueError consistently across platforms.
4954
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004955- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4956 (64bit Unix, for example), unichr() would truncate its argument and return
4957 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4958
Neal Norwitze7d8be82008-07-31 17:17:14 +00004959- Apply security patches from Apple.
4960
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004961- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4962 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4963
Antoine Pitrou92f82162008-07-25 22:22:08 +00004964- Issue #1819: function calls with several named parameters are now on
4965 average 35% faster (as measured by pybench).
4966
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004967- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4968 the python debugger steps into a class statement: the free variables (local
4969 variables defined in an outer scope) would be deleted from the outer scope.
4970
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004971- Issue #2620: Overflow checking when allocating or reallocating memory
4972 was not always being done properly in some python types and extension
4973 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4974 all been updated to perform better checks and places in the code that
4975 would previously leak memory on the error path when such an allocation
4976 failed have been fixed.

4979-------
4980

4982
Benjamin Petersone977ad42008-08-20 01:42:01 +00004983- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4984 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4985
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004986- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4987 version reported by these tools does not necessarily follow the python
4988 version numbering scheme, so the module is less strict when parsing it.
4989
Nick Coghlanf70385a2008-08-18 12:42:46 +00004990- Issue #2235: Added Py3k warnings for types which will become unhashable
4991 under the stricter __hash__ inheritance rules in 3.0. Several types
4992 which did not meet the rules for hash invariants and were already
4993 unhashable in 3.0 have now been explicitly flagged as unhashable in
4994 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4995 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4996
Brett Cannon88f801d2008-08-18 00:46:22 +00004997- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5005
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005006- Issue #3575: Incremental decoder's decode function now takes bytearray
5007 by using 's*' instead of 't#'.
5008
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005009- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005010 fails unicode conversion on 2nd parameter. (windows only)
5011
Georg Brandl222e2082010-08-01 22:27:39 +00005012- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005013 in a redirect.
5014

Brett Cannon721b1452008-08-16 22:00:27 +00005016 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005017
Facundo Batistaeb90b782008-08-16 14:44:07 +00005018- Issue #2776: fixed small issue when handling an URL with double slash
5019 after a 302 response in the case of not going through a proxy.
5020
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005021- Issue #2676: in the email package, content-type parsing was hanging on
5022 pathological input because of quadratic or exponential behaviour of a
5023 regular expression.
5024
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005025- Issue #3476: binary buffered reading through the new "io" library is now
5026 thread-safe.
5027
Brett Cannonbf3157b2008-08-14 05:00:03 +00005028- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5029 since mimetools itself is deprecated. Because modules are cached, all
5030 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5031
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005032- Issue #3134: shutil referenced undefined WindowsError symbol.
5033
Robert Schuppenies14646332008-08-10 11:01:53 +00005034- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5035 menu entries were not deleted.
5036
Brett Cannon83e81842008-08-09 23:30:55 +00005037- Copied the implementation of reduce() to _functools.reduce() to have a
5038 version that did not raise a DeprecationWarning under -3.
5039
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005040- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5041 a MemoryError rather than silently stop the iteration.
5042
Guido van Rossum59ce9012008-08-09 14:55:34 +00005043- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5044 to _sre.compile() will now be rejected. This should not affect anybody
5045 since the re.compile() function never generates invalid re-bytecode.
5046
Skip Montanaroa032bf42008-08-08 22:52:51 +00005047- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5048 upon first access it can be automatically initialized from the csv file if
5049 it wasn't initialized during instantiation.
5050
Brett Cannon3aa2a492008-08-06 22:28:09 +00005051- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5052 the reload() built-in has been removed.
5053

Antoine Pitroude781a42008-08-09 12:43:23 +00005066 asking for a specific length. This problem only affected files opened
5067 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005068

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005117What's New in Python 2.6 beta 2?
5118================================
5119
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005120*Release date: 17-Jul-2008*
5121
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005122Core and Builtins
5123-----------------
5124
Georg Brandl3e483f62008-07-16 22:57:41 +00005125- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5126 its methods now allow for items objects that can be converted to
5127 an integer using operator.index().
5128
Mark Dickinson64b7e502008-07-16 09:40:03 +00005129- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5130 produced a ValueError instead of giving the correct float.
5131
Eric Smitha5fa5a22008-07-16 00:11:49 +00005132- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5133 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5134
Mark Dickinson7103aa42008-07-15 19:08:33 +00005135- Issue #3008: the float type has a new instance method 'float.hex'
5136 and a new class method 'float.fromhex' to convert floating-point
5137 numbers to and from hexadecimal strings, respectively.
5138
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005139- Issue #2235: __hash__ is once again inherited by default. To allow
5140 collections.Hashable to remain meaningful in the presence of the
5141 default hash implementation (object.__hash__), it is now possible
5142 to explicit block inheritance of hash by setting __hash__=None at
5143 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5144 level.
5145
Nick Coghlanb028f502008-07-13 14:52:36 +00005146- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5147 the parent module cannot be found while performing an absolute import.
5148 This means that an incorrectly defined __package__ attribute will
5149 now only prevent relative imports in that module rather than causing
5150 all imports from that module to fail.
5151
Nick Coghlan14ff9942008-07-08 14:21:42 +00005152- Issue #2517: Allow unicode messages in Exceptions again by correctly
5153 bypassing the instance dictionary when looking up __unicode__ on
5154 new-style classes.
5155
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005156- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5157 set to a custom object whose write() method happens to install
5158 another file in sys.stdout.
5159
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005160- Issue #3088: Corrected a race condition in classes derived from
5161 threading.local: the first member set by a thread could be saved in
5162 another thread's dictionary.
5163
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005164- Issue #3004: Minor change to slice.indices(): the start and stop
5165 arguments are now treated identically, making the behaviour easier
5166 to describe and understand. For example, slice(None, -10,
5167 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5168 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5169 10, -1).
5170
Georg Brandl278fc502008-07-19 12:46:12 +00005171- Issue #3219: Calling a function with repeated keyword arguments,
5172 f(a=2, a=23), would not cause a syntax error. This was a regression
5173 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005174
Georg Brandl278fc502008-07-19 12:46:12 +00005175- Issue #2862: Make int and float freelist management consistent with
5176 other freelists. Changes their CompactFreeList apis into
5177 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005178
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005179Library
5180-------
5181
Thomas Heller57adf222008-08-14 19:10:48 +00005182- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5183 api functions without holding the GIL, which could lead to a fatal
5184 error when they failed.
5185
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005186- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5187
Jesse Noller7fb96402008-07-17 21:01:05 +00005188- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

5193
Jesse Noller13e9d582008-07-16 14:32:36 +00005194- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5195 ForkingPickler.register() to resolve conflict with ctypes.
5196
Vinay Sajip51e65192008-07-18 09:01:10 +00005197- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005198
Thomas Heller880f5292008-07-15 19:39:38 +00005199- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5200 a valid dlerror() message.
5201
Thomas Heller2bad6572008-07-15 17:19:50 +00005202- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5203 incomplete structure was created.
5204
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005205- Issue #3339: dummy_thread.acquire() should not return None.
5206
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005207- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5208
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005209- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005210
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005211- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5212 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005213 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005214 content-length. The problem had been corrected in the 2.4 branch, but never
5215 merged into trunk.
5216
Georg Brandle78fbcc2008-07-05 10:13:36 +00005217- Issue #2663: add filtering capability to shutil.copytree().
5218

5220
5221- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5222
5223- Issue #1746: Correct handling of zipfile archive comments (previously
5224 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005225 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005226
Vinay Sajip51e65192008-07-18 09:01:10 +00005227- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005228 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005229
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005230- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5231 handling is now the same as that of other special attributes like __name__).
5232
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005233- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5234 removal in Python 3.0 in favor of urllib2.urlopen().

5241 Prevents a deadlock.
5242
Gregory P. Smithc4691ec2008-07-07 05:09:12 +00005243- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
5244 redundant ":443" port number designation when the connection is using the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005685- Issue #1631171: Re-implement the 'warnings' module in C (the
5686 original Python code has been kept as backup). This will allow for
5687 using the 'warning's machinery in such places as the parser where
5688 use of pure Python code is not possible. Both the ``showarning()``
5689 and ``formatwarning()`` gain an optional 'line' argument which is
5690 not called by default for backwards-compatibility reasons. Setting
5691 ``warnings.showwarning()`` to an implementation that lacks support
5692 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005755- Issue #2550: The approach used by client/server code for obtaining
5756 ports to listen on in network-oriented tests has been refined in an
5757 effort to facilitate running multiple instances of the entire
5758 regression test suite in parallel without issue.
5759 test_support.bind_port() has been fixed such that it will always
5760 return a unique port -- which wasn't always the case with the
5761 previous implementation, especially if socket options had been set
5762 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5763 new implementation of bind_port() will actually raise an exception
5764 if it is passed an AF_INET/SOCK_STREAM socket with either the
5765 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5766 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5767 the socket it's been passed. This currently only applies to
5768 Windows. This option prevents any other sockets from binding to the
5769 host/port we've bound to, thus removing the possibility of the
5770 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5771 when a second SOCK_STREAM socket binds and accepts to a host/port
5772 that's already been bound by another socket. The optional preferred
5773 port parameter to bind_port() has been removed. Under no
5774 circumstances should tests be hard coding ports!
5775
5776 test_support.find_unused_port() has also been introduced, which will
5777 pass a temporary socket object to bind_port() in order to obtain an
5778 unused port. The temporary socket object is then closed and
5779 deleted, and the port is returned. This method should only be used
5780 for obtaining an unused port in order to pass to an external program
5781 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5782 a parameter to a server-oriented class that doesn't give you direct
5783 access to the underlying socket used.
5784
5785 Finally, test_support.HOST has been introduced, which should be used
5786 for the host argument of any relevant socket calls (i.e. bind and
5787 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005788
5789 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005791 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5792 test_asynchat and test_socket_ssl.
5793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794 It is now possible for multiple instances of the regression test
5795 suite to run in parallel without issue.

5951 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00005952 platform.machine() and platform.processor() will report this
5953 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00006074- Added the future_builtins module, which contains hex() and oct().
6075 These are the PEP 3127 version of these functions, designed to be
6076 compatible with the hex() and oct() builtins from Python 3.0. They
6077 differ slightly in their output formats from the existing, unchanged
6078 Python 2.6 builtins. The expected usage of the future_builtins
6079 module is:
6080 from future_builtins import hex, oct
6081
Eric Smith7ef40bf2008-02-20 23:34:22 +00006082- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6083 exponents for exponents with absolute value < 100. Follows C99
6084 standard. This is a change on Windows, which would use 3 digits.
6085 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6086 so that any alterations it does to the resulting string will be
6087 available in stringlib/formatter.h (for float.__format__).
6088
Eric Smith5a3c1352008-02-19 13:21:56 +00006089- Implemented PEP 3101, Advanced String Formatting. This adds a new
6090 builtin format(); a format() method for str and unicode; a
6091 __format__() method to object, str, unicode, int, long, float, and
6092 datetime; the class string.Formatter; and the C API
6093 PyObject_Format().
6094
Georg Brandl3ee81df2008-05-17 18:14:43 +00006095- Fixed several potential crashes, all caused by specially crafted
6096 __del__ methods exploiting objects in temporarily inconsistent
6097 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006098
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006099- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006100 prevent a possible crash: an Abstract Base Class would try to access
6101 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006106- Clear all free lists during a gc.collect() of the highest generation
6107 in order to allow pymalloc to free more arenas. Python may give back
6108 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006109
Georg Brandl3ee81df2008-05-17 18:14:43 +00006110- Issue #2045: Fix an infinite recursion triggered when printing a
6111 subclass of collections.defaultdict, if its default_factory is set
6112 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006113
Christian Heimesf75dbef2008-02-08 00:11:31 +00006114- Fixed a minor memory leak in dictobject.c. The content of the free
6115 list was not freed on interpreter shutdown.
6116
Georg Brandl21e99f42010-03-07 15:23:59 +00006117- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006119
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6121 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006122 to compact the internal free lists of pre-allocted ints and floats.
6123
Georg Brandl3ee81df2008-05-17 18:14:43 +00006124- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6125 calls. Python expected the return type int but the fork familie
6126 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006127

Georg Brandl3ee81df2008-05-17 18:14:43 +00006140- Patch #1473257: generator objects gain a gi_code attribute. This is
6141 the same object as the func_code attribute of the function that
6142 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006143
Georg Brandl3ee81df2008-05-17 18:14:43 +00006144- Issue #1920: "while 0" statements were completely removed by the
6145 compiler, even in the presence of an "else" clause, which is
6146 supposed to be run when the condition is false. Now the compiler
6147 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006148
Guido van Rossumeead05f2008-01-24 18:21:02 +00006149- A few crashers fixed: weakref_in_del.py (issue #1377858);
6150 loosing_dict_ref.py (issue #1303614, test67.py);
6151 borrowed_ref_[34].py (not in tracker).
6152

6156
Georg Brandl3ee81df2008-05-17 18:14:43 +00006157- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006158 several extension methods and modules do not work without unicode
6159 support.
6160
Georg Brandl26543b12008-01-21 18:36:51 +00006161- Issue #1882: when compiling code from a string, encoding cookies in the

6163
Georg Brandl14404b62008-01-19 19:27:05 +00006164- Issue #1679: "0x" was taken as a valid integer literal.
6165
Georg Brandl6caad7d2008-01-26 14:19:22 +00006166- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006167 added.
6168
Christian Heimesc94e2b52008-01-14 04:13:37 +00006169- sys.float_info / PyFloat_GetInfo: The floating point information
6170 object was converted from a dict to a specialized structseq object.
6171
Georg Brandl3ee81df2008-05-17 18:14:43 +00006172- Patch #1816: Added sys.flags structseq. It exposes the status of
6173 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006174
Georg Brandl3ee81df2008-05-17 18:14:43 +00006175- Objects/structseq.c: Implemented new structseq representation. The

6186
Georg Brandl3ee81df2008-05-17 18:14:43 +00006187- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6188 envvar and sys.dont_write_bytecode attribute. All these can be set
6189 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006190
Georg Brandl3ee81df2008-05-17 18:14:43 +00006191- Improve some exception messages when Windows fails to load an
6192 extension module. Now we get for example '%1 is not a valid Win32
6193 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006200- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006201 and INF. float("nan"), float("inf") and float("-inf") now work on
6202 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006204- Compiler now generates simpler and faster code for dictionary
6205 literals. The oparg for BUILD_MAP now indicates an estimated
6206 dictionary size. There is a new opcode, STORE_MAP, for adding
6207 entries to the dictionary.

6237 file can now be directly executed by passing their name to the
6238 interpreter. The directory/zipfile is automatically inserted as the
6239 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006241- Issue #1265: Fix a problem with sys.settrace, if the tracing
6242 function uses a generator expression when at the same time the
6243 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006244
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006245- sets and frozensets now have an isdisjoint() method.

6250
Georg Brandl21e99f42010-03-07 15:23:59 +00006251- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006252 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6253 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006254
Georg Brandl3ee81df2008-05-17 18:14:43 +00006255- Issue #1686386: Tuple's tp_repr did not take into account the
6256 possibility of having a self-referential tuple, which is possible
6257 from C code. Nor did object's tp_str consider that a type's tp_str
6258 could do something that could lead to an inifinite recursion.
6259 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6260 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006261
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262- Issue #1164: It was possible to trigger deadlock when using the
6263 'print' statement to write to a file since the GIL was not released
6264 as needed. Now PyObject_Print() does the right thing along with
6265 various tp_print implementations of the built-in types and those in
6266 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006267
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00006274
Brett Cannon1e534b52007-09-07 04:18:30 +00006275- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006276 PyObject_Call() never calling back out to Python code to trigger
6277 recursion depth updates/checks. Required the creation of a static
6278 RuntimeError instance in case normalizing an exception put the
6279 recursion check value past its limit. Fixes crashers
6280 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006281

Neal Norwitz0ac60192007-05-27 04:08:54 +00006295- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006296 __*__ attributes. (Some already existed, e.g., __doc__ and
6297 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006298
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006299- Add -3 option to the interpreter to warn about features that are
6300 deprecated and will be changed/removed in Python 3.0.
6301
Georg Brandl2134e752007-05-21 20:34:16 +00006302- Patch #1686487: you can now pass any mapping after '**' in function
6303 calls.
6304
Collin Winter62903052007-05-18 23:11:24 +00006305- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006306 "except E as target:". This is to provide forwards compatibility
6307 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006314- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006315 setting a plain string, ie don't expand to single letter identifiers.
6316
Raymond Hettinger13936692007-04-11 18:40:58 +00006317- Request #1191699: Slices can now be pickled.
6318
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006319- Request #1193128: str.translate() now allows a None argument for
6320 translations that only remove characters without re-mapping the
6321 remaining characters.
6322
Georg Brandl5cb76c12007-03-21 09:00:39 +00006323- Patch #1682205: a TypeError while unpacking an iterable is no longer

6327
Guido van Rossum143b5642007-03-23 04:58:42 +00006328- Bug #1683368: The object.__init__() and object.__new__() methods are
6329 now stricter in rejecting excess arguments. The only time when
6330 either allows excess arguments is when it is not overridden and the
6331 other one is. For backwards compatibility, when both are
6332 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006333 warning later). Also, type.__init__() insists on the same signature
6334 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006335
Georg Brandl3ee81df2008-05-17 18:14:43 +00006336- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6337 object to complex using its __complex__() method before falling back
6338 to the __float__() method. Therefore, the functions in the cmath
6339 module now can operate on objects that define a __complex__()
6340 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006342- Patch #1623563: allow __class__ assignment for classes with
6343 __slots__. The old and the new class are still required to have the
6344 same slot names.

6351 its type.

6357
Georg Brandl7b9c5552007-03-12 14:30:05 +00006358- Bug #1678647: write a newline after printing an exception in any
6359 case, even when converting the value to a string failed.
6360
Georg Brandl871f1bc2007-03-12 13:17:36 +00006361- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006362 its argument, if it exists. If not, it will work like before. This
6363 allows customizing the output of dir() in the presence of a
6364 __getattr__().

6373 parthensized forms. This means complex(repr(x)) now works instead of
6374 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006375
Georg Brandlaa2321b2007-03-07 00:40:28 +00006376- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006377 makes the filenames the warning module prints much more sensible
6378 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006379

Georg Brandl0fca97a2007-03-05 22:28:08 +00006391- Patch #1674228: when assigning a slice (old-style), check for the
6392 sq_ass_slice instead of the sq_slice slot.
6393
Georg Brandl3ee81df2008-05-17 18:14:43 +00006394- When printing an unraisable error, don't print exceptions. before
6395 the name. This duplicates the behavior whening normally printing
6396 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006929 AttributeError instead of an IOError when the server's response
6930 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006931

Georg Brandl3ee81df2008-05-17 18:14:43 +00006947- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl92a6bae2007-03-13 17:43:32 +00006963- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006964 are set for invalid interpolation sequences that would lead to
6965 errors on reading back those values.

7008 returned string up to the first NUL character.

7021 TestCase and TestSuite subclasses (not instances) are no longer
7022 accepted in TestSuite.addTest(). This should cause no
7023 incompatibility since it never made sense with ordinary subclasses
7024 -- the failure just occurred later, with a more cumbersome
7025 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007414 time so that opening a database previously created with the DB_DUP
7415 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7416 opens. Specifically: dictionary assignment to a DB object will
7417 replace all values for a given key when the database allows
7418 duplicate values. DB users should use DB.put(k, v) when they want
7419 to store duplicates; not DB[k] = v.

7428 behavior of quoting dots if they are the second character of any
7429 line.

7775 of w# format code incorrectly truncated the length to an int, even
7776 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7777 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007807- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7808 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
