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 +00001285- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1286 This prevents user-created self-referencing ordered dictionaries from
1287 becoming permanently uncollectable GC garbage. The downside is that
1288 removing __del__ means that the internal doubly-linked list has to wait for
1289 GC collection rather than freeing memory immediately when the refcnt drops
1290 to zero.
1291
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001292- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1295
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001296- Issue #9792: In case of connection failure, socket.create_connection()
1297 would swallow the exception and raise a new one, making it impossible
1298 to fetch the original errno, or to filter timeout errors. Now the
1299 original error is re-raised.

1320
R. David Murray7c4bf552010-08-25 01:45:57 +00001321- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1322 character years even if the message contains RFC822 two character years.
1323
Daniel Stutzbach91287322010-08-24 21:09:30 +00001324- Issue #8750: Fixed MutableSet's methods to correctly handle

1340
Benjamin Peterson52c36052010-08-21 03:03:22 +00001341- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001356- Issue #9550: a BufferedReader could issue an additional read when the
1357 original read request had been satisfied, which could block indefinitely
1358 when the underlying raw IO channel was e.g. a socket. Report and original
1359 patch by Jason V. Miller.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002135- Issue #7301: Add environment variable $PYTHONWARNINGS.
2136
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002137- Issue #8329: Don't return the same lists from select.select when no fds are
2138 changed.
2139
Georg Brandlfee0f442010-05-22 21:26:21 +00002140- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002141 on 64-bit machines. The shift count for either left or right shift is
2142 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002150- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2151 with a non-empty format string. This is an effort to future-proof user
2152 code. If a derived class does not currently implement __format__ but later
2153 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002154 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002155 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002188- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00002205- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2206 InvalidOperation instead of returning False. (Comparisons involving a quiet
2207 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2208 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002209
Georg Brandlfee0f442010-05-22 21:26:21 +00002210- Issue #2531: Comparison operations between floats and Decimal instances now
2211 return a result based on the numeric values of the operands; previously they
2212 returned an arbitrary result based on the relative ordering of id(float) and
2213 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002215- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002216 argument `-` which tells it to read files to compile from stdin. Each line is
2217 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00002227- Comparisons using one of <, <=, >, >= between a complex instance and a
2228 Fractions instance now raise TypeError instead of returning True/False. This
2229 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2230 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002587- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2588 and add the additional members returned in an OSVERSIONINFOEX structure. The
2589 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002592- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2593 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2594 returning NULL. The macro now returns a statically allocated empty string
2595 instead.

2605 strings,
2606 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2607 numeric strings corresponding to subnormal values,
2608 (3) a memory leak for some values large enough to cause overflow, and
2609 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002640- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002641 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002642 Also, raise ValueError rather than TypeError when an unknown TIPC address
2643 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002647- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002648 file position when calling `truncate()`. It would previously change the file
2649 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002650 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2651
Georg Brandlba83f822010-03-14 09:50:54 +00002652- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2653 class used to represent files stored inside an archive. The new
2654 implementation is significantly faster and can be wrapped in a
2655 ``io.BufferedReader`` object for more speedups. It also solves an issue
2656 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002667- Issue #7748: Since unicode values are supported for some metadata options in
2668 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2669 encoded string for them. This ensures that the upload and register commands
2670 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00002739What's New in Python 2.7 alpha 2?
2740=================================

2745-----------------
2746
Georg Brandlba83f822010-03-14 09:50:54 +00002747- The ``__complex__()`` method is now looked up on the class of instances to
2748 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002749
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002750- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2751 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2752
Mark Dickinson1b34d252010-01-01 17:27:30 +00002753- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002754 DeprecationWarning when passed a float argument where an integer was expected.
2755 These functions and methods now raise TypeError instead. The majority of the
2756 effects of this change are in the extension modules, but some core functions
2757 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2758 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002759

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002768- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2769 used to drop the time part of the result.
2770
Georg Brandlba83f822010-03-14 09:50:54 +00002771- Issue #1811: Improve accuracy and cross-platform consistency for true division
2772 of integers: the result of a/b is now correctly rounded for ints a and b (at
2773 least on IEEE 754 platforms), and in particular does not depend on the
2774 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002775
Georg Brandlba83f822010-03-14 09:50:54 +00002776- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2777 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2778 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002779

Ronald Oussoren92919a62009-12-24 13:30:58 +00002781 executables on OSX.
2782
Georg Brandlba83f822010-03-14 09:50:54 +00002783 These executables now work properly with the arch(1) command: ``arch -ppc
2784 python`` will start a universal binary version of python in PPC mode (unlike
2785 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002786
Georg Brandlba83f822010-03-14 09:50:54 +00002787- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2788 underlying error when the coercion fails for the left hand operand.

2800 allowing for a maximum number of tasks within the pool to be completed by the
2801 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00002807- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002808 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2809 alternative to cPickle if you care about performance. Patch by Florent

Gregory P. Smith79a3eb12010-01-03 01:29:44 +00002827
Georg Brandlba83f822010-03-14 09:50:54 +00002828- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00002829 Initial patch by Brian Curtin.
2830
Georg Brandlba83f822010-03-14 09:50:54 +00002831- Distutils now correctly identifies the build architecture as "x86_64" when
2832 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00002833

Georg Brandlba83f822010-03-14 09:50:54 +00002837- Issue #7552: Removed line feed in the base64 Authorization header in the
2838 Distutils upload command to avoid an error when PyPI reads it. This occurs on
2839 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +00002840

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002844- Issue #7349: Make methods of file objects in the io module accept None as an
2845 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2846 the same as passing no argument.
2847
Georg Brandlba83f822010-03-14 09:50:54 +00002848- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00002870- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2871 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2872 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2873 float arguments for integer format codes (other than 'L'): previously an

2875 TypeError. For the 'L' format code (which previously had no warning) there is
2876 now a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00002941- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2942 decimal string that's guaranteed to round back to x under correct rounding
2943 (with round-half-to-even rounding mode). Previously it gave a string based on
2944 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2945 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2946 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002947
Georg Brandlba83f822010-03-14 09:50:54 +00002948- Issue #7117: On almost all platforms: float-to-string and string-to-float
2949 conversions within Python are now correctly rounded. Places these conversions
2950 occur include: str for floats and complex numbers; the float and complex
2951 constructors; old-style and new-style numeric formatting; serialization and
2952 deserialization of floats and complex numbers using marshal, pickle and json;
2953 parsing of float and imaginary literals in Python code; Decimal-to-float
2954 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002955
Georg Brandlba83f822010-03-14 09:50:54 +00002956 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2957 providing correctly-rounded strtod and dtoa C functions. This code is
2958 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2959 the C compiler. There may be a small number of platforms on which correct
2960 operation of this code cannot be guaranteed, so the code is not used: notably,
2961 this applies to platforms where the C double format is not IEEE 754 binary64,
2962 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2963 and Python's configure script is unable to determine how to change the FPU
2964 precision. On these platforms conversions use the platform strtod and dtoa,
2965 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002966
Georg Brandlba83f822010-03-14 09:50:54 +00002967- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2968 uses the correctly-rounded string <-> float conversions described above (when
2969 available), and so produces correctly rounded results that will display nicely
2970 under the float repr. There are two related small changes: (1) round now
2971 accepts any class with an ``__index__()`` method for its second argument (but
2972 no longer accepts floats for the second argument), and (2) an excessively
2973 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2974 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003192 untrackable objects are not tracked by the garbage collector. This can reduce
3193 the size of collections and therefore the garbage collection overhead on
3194 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00003200- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
3201 internal representation of integers, for performance reasons. Base 2**30 is
3202 enabled by default on 64-bit machines. Add --enable-big-digits option to
3203 configure, which overrides the default. Add sys.long_info structseq to
3204 provide information about the internal format.

3235
Georg Brandl29c6a282009-04-05 20:23:13 +00003236- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003237 were suppressing all exceptions. These include list(), filter(), map(),

3239
Benjamin Peterson596d3062009-01-19 15:42:23 +00003240- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

3249 str, bytes and bytearray could be optimized away by the compiler, letting the
3250 interpreter segfault instead of raising an error.

3266
Georg Brandlba83f822010-03-14 09:50:54 +00003267- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3268 existing .py counterpart, override the co_filename attributes of all code
3269 objects if the original filename is obsolete (which can happen if the file has
3270 been renamed, moved, or if it is accessed through different paths). Patch by

3324
Georg Brandlba83f822010-03-14 09:50:54 +00003325- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3326 file objects with closefd=False. The file descriptor is still kept open but
3327 the file object behaves like a closed file. The ``FileIO`` object also got a
3328 new readonly attribute ``closefd``.

3347
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003348- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003351- On windows, ``os.chdir()`` given unicode was not working if
3352 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3353 this code path is really executed because I cannot move to such directory on
3354 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003356- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3357 element is temporarily replaced with an equivalent frozenset. But the
3358 eventual KeyError would always report the empty ``frozenset()`` as the missing
3359 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003379- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3380 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3381 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3382 of using the replace error handler in PyUnicode_DecodeUTF8().
3383
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003384- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003387- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3389 gives improved memory leak detection when running under Valgrind, while taking
3390 advantage of pymalloc at other times.

4556 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4557 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4558 neither __int__ nor __long__, TypeError used to be raised (with a
4559 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4560 struct.error in other cases.

4563 argument with an __int__ method can be packed, but use of this feature
4564 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004757- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4759 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4760 ``printf`` function, whereas PyString_FromFormat has an independent
4761 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004858 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4859 for catch_warnings() also led to an improvement in the raising of a
4860 DeprecationWarning related to warnings.warn_explicit().
4861

4884
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004885- Issue #2975: When compiling several extension modules with Visual Studio 2008

4887 without limit.
4888
Benjamin Peterson37346b22008-08-23 20:27:43 +00004889- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004926What's New in Python 2.6 beta 3?
4927================================
4928
Barry Warsaw07a4a382008-08-21 01:15:08 +00004929*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004930
4931Core and Builtins
4932-----------------
4933
Guido van Rossumf8402962008-08-20 15:01:50 +00004934- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4935 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4936 extensions do not automatically benefit from the class attribute
4937 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4938 to their tp_flags field if they care. This is a backwards
4939 compatibility feature; in 3.0, all types will use the cache by
4940 default.
4941
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004942- Keyword arguments can now follow starred arguments. (``f(a, *args,
4943 keyword=23)`` is now valid syntax.)
4944
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004945- ctypes function pointers that are COM methods have a boolean True
4946 value again.
4947
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004948- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4949 by denying s# to parse objects that have a releasebuffer procedure,
4950 and introducing s*.
4951
Georg Brandl1e13ea92008-08-11 09:07:59 +00004952- Issue #3537: Fix an assertion failure when an empty but presized dict
4953 object was stored in the freelist.
4954
Mark Dickinsonb6467572008-08-04 21:30:09 +00004955- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4956 ValueError consistently across platforms.
4957
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004958- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4959 (64bit Unix, for example), unichr() would truncate its argument and return
4960 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4961
Neal Norwitze7d8be82008-07-31 17:17:14 +00004962- Apply security patches from Apple.
4963
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004964- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4965 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4966
Antoine Pitrou92f82162008-07-25 22:22:08 +00004967- Issue #1819: function calls with several named parameters are now on
4968 average 35% faster (as measured by pybench).
4969
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004970- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4971 the python debugger steps into a class statement: the free variables (local
4972 variables defined in an outer scope) would be deleted from the outer scope.
4973
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004974- Issue #2620: Overflow checking when allocating or reallocating memory
4975 was not always being done properly in some python types and extension
4976 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4977 all been updated to perform better checks and places in the code that
4978 would previously leak memory on the error path when such an allocation
4979 failed have been fixed.

4982-------
4983

4985
Benjamin Petersone977ad42008-08-20 01:42:01 +00004986- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4987 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4988
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004989- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4990 version reported by these tools does not necessarily follow the python
4991 version numbering scheme, so the module is less strict when parsing it.
4992
Nick Coghlanf70385a2008-08-18 12:42:46 +00004993- Issue #2235: Added Py3k warnings for types which will become unhashable
4994 under the stricter __hash__ inheritance rules in 3.0. Several types
4995 which did not meet the rules for hash invariants and were already
4996 unhashable in 3.0 have now been explicitly flagged as unhashable in
4997 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4998 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4999
Brett Cannon88f801d2008-08-18 00:46:22 +00005000- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5008
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005009- Issue #3575: Incremental decoder's decode function now takes bytearray
5010 by using 's*' instead of 't#'.
5011
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005012- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005013 fails unicode conversion on 2nd parameter. (windows only)
5014
Georg Brandl222e2082010-08-01 22:27:39 +00005015- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005016 in a redirect.
5017

Brett Cannon721b1452008-08-16 22:00:27 +00005019 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005020
Facundo Batistaeb90b782008-08-16 14:44:07 +00005021- Issue #2776: fixed small issue when handling an URL with double slash
5022 after a 302 response in the case of not going through a proxy.
5023
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005024- Issue #2676: in the email package, content-type parsing was hanging on
5025 pathological input because of quadratic or exponential behaviour of a
5026 regular expression.
5027
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005028- Issue #3476: binary buffered reading through the new "io" library is now
5029 thread-safe.
5030
Brett Cannonbf3157b2008-08-14 05:00:03 +00005031- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5032 since mimetools itself is deprecated. Because modules are cached, all
5033 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5034
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005035- Issue #3134: shutil referenced undefined WindowsError symbol.
5036
Robert Schuppenies14646332008-08-10 11:01:53 +00005037- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5038 menu entries were not deleted.
5039
Brett Cannon83e81842008-08-09 23:30:55 +00005040- Copied the implementation of reduce() to _functools.reduce() to have a
5041 version that did not raise a DeprecationWarning under -3.
5042
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005043- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5044 a MemoryError rather than silently stop the iteration.
5045
Guido van Rossum59ce9012008-08-09 14:55:34 +00005046- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5047 to _sre.compile() will now be rejected. This should not affect anybody
5048 since the re.compile() function never generates invalid re-bytecode.
5049
Skip Montanaroa032bf42008-08-08 22:52:51 +00005050- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5051 upon first access it can be automatically initialized from the csv file if
5052 it wasn't initialized during instantiation.
5053
Brett Cannon3aa2a492008-08-06 22:28:09 +00005054- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5055 the reload() built-in has been removed.
5056
Brett Cannon7e30b672008-08-04 21:52:25 +00005057- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00005069 asking for a specific length. This problem only affected files opened
5070 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005071

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005120What's New in Python 2.6 beta 2?
5121================================
5122
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005123*Release date: 17-Jul-2008*
5124
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005125Core and Builtins
5126-----------------
5127
Georg Brandl3e483f62008-07-16 22:57:41 +00005128- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5129 its methods now allow for items objects that can be converted to
5130 an integer using operator.index().
5131
Mark Dickinson64b7e502008-07-16 09:40:03 +00005132- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5133 produced a ValueError instead of giving the correct float.
5134
Eric Smitha5fa5a22008-07-16 00:11:49 +00005135- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5136 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5137
Mark Dickinson7103aa42008-07-15 19:08:33 +00005138- Issue #3008: the float type has a new instance method 'float.hex'
5139 and a new class method 'float.fromhex' to convert floating-point
5140 numbers to and from hexadecimal strings, respectively.
5141
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005142- Issue #2235: __hash__ is once again inherited by default. To allow
5143 collections.Hashable to remain meaningful in the presence of the
5144 default hash implementation (object.__hash__), it is now possible
5145 to explicit block inheritance of hash by setting __hash__=None at
5146 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5147 level.
5148
Nick Coghlanb028f502008-07-13 14:52:36 +00005149- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5150 the parent module cannot be found while performing an absolute import.
5151 This means that an incorrectly defined __package__ attribute will
5152 now only prevent relative imports in that module rather than causing
5153 all imports from that module to fail.
5154
Nick Coghlan14ff9942008-07-08 14:21:42 +00005155- Issue #2517: Allow unicode messages in Exceptions again by correctly
5156 bypassing the instance dictionary when looking up __unicode__ on
5157 new-style classes.
5158
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005159- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5160 set to a custom object whose write() method happens to install
5161 another file in sys.stdout.
5162
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005163- Issue #3088: Corrected a race condition in classes derived from
5164 threading.local: the first member set by a thread could be saved in
5165 another thread's dictionary.
5166
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005167- Issue #3004: Minor change to slice.indices(): the start and stop
5168 arguments are now treated identically, making the behaviour easier
5169 to describe and understand. For example, slice(None, -10,
5170 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5171 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5172 10, -1).
5173
Georg Brandl278fc502008-07-19 12:46:12 +00005174- Issue #3219: Calling a function with repeated keyword arguments,
5175 f(a=2, a=23), would not cause a syntax error. This was a regression
5176 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005177
Georg Brandl278fc502008-07-19 12:46:12 +00005178- Issue #2862: Make int and float freelist management consistent with
5179 other freelists. Changes their CompactFreeList apis into
5180 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005181
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005182Library
5183-------
5184
Thomas Heller57adf222008-08-14 19:10:48 +00005185- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5186 api functions without holding the GIL, which could lead to a fatal
5187 error when they failed.
5188
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005189- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5190
Jesse Noller7fb96402008-07-17 21:01:05 +00005191- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

5196
Jesse Noller13e9d582008-07-16 14:32:36 +00005197- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5198 ForkingPickler.register() to resolve conflict with ctypes.
5199
Vinay Sajip51e65192008-07-18 09:01:10 +00005200- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005201
Thomas Heller880f5292008-07-15 19:39:38 +00005202- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5203 a valid dlerror() message.
5204
Thomas Heller2bad6572008-07-15 17:19:50 +00005205- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5206 incomplete structure was created.
5207
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005208- Issue #3339: dummy_thread.acquire() should not return None.
5209
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005210- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5211
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005212- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005213
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005214- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5215 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005216 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005217 content-length. The problem had been corrected in the 2.4 branch, but never
5218 merged into trunk.
5219
Georg Brandle78fbcc2008-07-05 10:13:36 +00005220- Issue #2663: add filtering capability to shutil.copytree().
5221

5223
5224- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5225
5226- Issue #1746: Correct handling of zipfile archive comments (previously
5227 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005228 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005229
Vinay Sajip51e65192008-07-18 09:01:10 +00005230- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005231 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005232
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005233- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5234 handling is now the same as that of other special attributes like __name__).
5235
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005236- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5237 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005688- Issue #1631171: Re-implement the 'warnings' module in C (the
5689 original Python code has been kept as backup). This will allow for
5690 using the 'warning's machinery in such places as the parser where
5691 use of pure Python code is not possible. Both the ``showarning()``
5692 and ``formatwarning()`` gain an optional 'line' argument which is
5693 not called by default for backwards-compatibility reasons. Setting
5694 ``warnings.showwarning()`` to an implementation that lacks support
5695 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005758- Issue #2550: The approach used by client/server code for obtaining
5759 ports to listen on in network-oriented tests has been refined in an
5760 effort to facilitate running multiple instances of the entire
5761 regression test suite in parallel without issue.
5762 test_support.bind_port() has been fixed such that it will always
5763 return a unique port -- which wasn't always the case with the
5764 previous implementation, especially if socket options had been set
5765 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5766 new implementation of bind_port() will actually raise an exception
5767 if it is passed an AF_INET/SOCK_STREAM socket with either the
5768 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5769 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5770 the socket it's been passed. This currently only applies to
5771 Windows. This option prevents any other sockets from binding to the
5772 host/port we've bound to, thus removing the possibility of the
5773 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5774 when a second SOCK_STREAM socket binds and accepts to a host/port
5775 that's already been bound by another socket. The optional preferred
5776 port parameter to bind_port() has been removed. Under no
5777 circumstances should tests be hard coding ports!
5778
5779 test_support.find_unused_port() has also been introduced, which will
5780 pass a temporary socket object to bind_port() in order to obtain an
5781 unused port. The temporary socket object is then closed and
5782 deleted, and the port is returned. This method should only be used
5783 for obtaining an unused port in order to pass to an external program
5784 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5785 a parameter to a server-oriented class that doesn't give you direct
5786 access to the underlying socket used.
5787
5788 Finally, test_support.HOST has been introduced, which should be used
5789 for the host argument of any relevant socket calls (i.e. bind and
5790 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005791
5792 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005793 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005794 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5795 test_asynchat and test_socket_ssl.
5796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797 It is now possible for multiple instances of the regression test
5798 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006077- Added the future_builtins module, which contains hex() and oct().
6078 These are the PEP 3127 version of these functions, designed to be
6079 compatible with the hex() and oct() builtins from Python 3.0. They
6080 differ slightly in their output formats from the existing, unchanged
6081 Python 2.6 builtins. The expected usage of the future_builtins
6082 module is:
6083 from future_builtins import hex, oct
6084
Eric Smith7ef40bf2008-02-20 23:34:22 +00006085- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6086 exponents for exponents with absolute value < 100. Follows C99
6087 standard. This is a change on Windows, which would use 3 digits.
6088 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6089 so that any alterations it does to the resulting string will be
6090 available in stringlib/formatter.h (for float.__format__).
6091
Eric Smith5a3c1352008-02-19 13:21:56 +00006092- Implemented PEP 3101, Advanced String Formatting. This adds a new
6093 builtin format(); a format() method for str and unicode; a
6094 __format__() method to object, str, unicode, int, long, float, and
6095 datetime; the class string.Formatter; and the C API
6096 PyObject_Format().
6097
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Fixed several potential crashes, all caused by specially crafted
6099 __del__ methods exploiting objects in temporarily inconsistent
6100 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006101
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006102- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006103 prevent a possible crash: an Abstract Base Class would try to access
6104 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006109- Clear all free lists during a gc.collect() of the highest generation
6110 in order to allow pymalloc to free more arenas. Python may give back
6111 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006112
Georg Brandl3ee81df2008-05-17 18:14:43 +00006113- Issue #2045: Fix an infinite recursion triggered when printing a
6114 subclass of collections.defaultdict, if its default_factory is set
6115 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006116
Christian Heimesf75dbef2008-02-08 00:11:31 +00006117- Fixed a minor memory leak in dictobject.c. The content of the free
6118 list was not freed on interpreter shutdown.
6119
Georg Brandl21e99f42010-03-07 15:23:59 +00006120- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006122
Georg Brandl3ee81df2008-05-17 18:14:43 +00006123- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6124 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006125 to compact the internal free lists of pre-allocted ints and floats.
6126
Georg Brandl3ee81df2008-05-17 18:14:43 +00006127- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6128 calls. Python expected the return type int but the fork familie
6129 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006130

Georg Brandl3ee81df2008-05-17 18:14:43 +00006143- Patch #1473257: generator objects gain a gi_code attribute. This is
6144 the same object as the func_code attribute of the function that
6145 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006146
Georg Brandl3ee81df2008-05-17 18:14:43 +00006147- Issue #1920: "while 0" statements were completely removed by the
6148 compiler, even in the presence of an "else" clause, which is
6149 supposed to be run when the condition is false. Now the compiler
6150 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006151
Guido van Rossumeead05f2008-01-24 18:21:02 +00006152- A few crashers fixed: weakref_in_del.py (issue #1377858);
6153 loosing_dict_ref.py (issue #1303614, test67.py);
6154 borrowed_ref_[34].py (not in tracker).
6155

6159
Georg Brandl3ee81df2008-05-17 18:14:43 +00006160- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006161 several extension methods and modules do not work without unicode
6162 support.
6163
Georg Brandl26543b12008-01-21 18:36:51 +00006164- Issue #1882: when compiling code from a string, encoding cookies in the

6166
Georg Brandl14404b62008-01-19 19:27:05 +00006167- Issue #1679: "0x" was taken as a valid integer literal.
6168
Georg Brandl6caad7d2008-01-26 14:19:22 +00006169- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006170 added.
6171
Christian Heimesc94e2b52008-01-14 04:13:37 +00006172- sys.float_info / PyFloat_GetInfo: The floating point information
6173 object was converted from a dict to a specialized structseq object.
6174
Georg Brandl3ee81df2008-05-17 18:14:43 +00006175- Patch #1816: Added sys.flags structseq. It exposes the status of
6176 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006177
Georg Brandl3ee81df2008-05-17 18:14:43 +00006178- Objects/structseq.c: Implemented new structseq representation. The

6189
Georg Brandl3ee81df2008-05-17 18:14:43 +00006190- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6191 envvar and sys.dont_write_bytecode attribute. All these can be set
6192 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006193
Georg Brandl3ee81df2008-05-17 18:14:43 +00006194- Improve some exception messages when Windows fails to load an
6195 extension module. Now we get for example '%1 is not a valid Win32
6196 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006203- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006204 and INF. float("nan"), float("inf") and float("-inf") now work on
6205 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006207- Compiler now generates simpler and faster code for dictionary
6208 literals. The oparg for BUILD_MAP now indicates an estimated
6209 dictionary size. There is a new opcode, STORE_MAP, for adding
6210 entries to the dictionary.

6240 file can now be directly executed by passing their name to the
6241 interpreter. The directory/zipfile is automatically inserted as the
6242 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006244- Issue #1265: Fix a problem with sys.settrace, if the tracing
6245 function uses a generator expression when at the same time the
6246 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006247
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006248- sets and frozensets now have an isdisjoint() method.

6253
Georg Brandl21e99f42010-03-07 15:23:59 +00006254- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006255 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6256 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006257
Georg Brandl3ee81df2008-05-17 18:14:43 +00006258- Issue #1686386: Tuple's tp_repr did not take into account the
6259 possibility of having a self-referential tuple, which is possible
6260 from C code. Nor did object's tp_str consider that a type's tp_str
6261 could do something that could lead to an inifinite recursion.
6262 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6263 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006264
Georg Brandl3ee81df2008-05-17 18:14:43 +00006265- Issue #1164: It was possible to trigger deadlock when using the
6266 'print' statement to write to a file since the GIL was not released
6267 as needed. Now PyObject_Print() does the right thing along with
6268 various tp_print implementations of the built-in types and those in
6269 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006270
Georg Brandl3ee81df2008-05-17 18:14:43 +00006271- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00006277
Brett Cannon1e534b52007-09-07 04:18:30 +00006278- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006279 PyObject_Call() never calling back out to Python code to trigger
6280 recursion depth updates/checks. Required the creation of a static
6281 RuntimeError instance in case normalizing an exception put the
6282 recursion check value past its limit. Fixes crashers
6283 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006284

Neal Norwitz0ac60192007-05-27 04:08:54 +00006298- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006299 __*__ attributes. (Some already existed, e.g., __doc__ and
6300 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006301
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006302- Add -3 option to the interpreter to warn about features that are
6303 deprecated and will be changed/removed in Python 3.0.
6304
Georg Brandl2134e752007-05-21 20:34:16 +00006305- Patch #1686487: you can now pass any mapping after '**' in function
6306 calls.
6307
Collin Winter62903052007-05-18 23:11:24 +00006308- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006309 "except E as target:". This is to provide forwards compatibility
6310 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006317- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006318 setting a plain string, ie don't expand to single letter identifiers.
6319
Raymond Hettinger13936692007-04-11 18:40:58 +00006320- Request #1191699: Slices can now be pickled.
6321
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006322- Request #1193128: str.translate() now allows a None argument for
6323 translations that only remove characters without re-mapping the
6324 remaining characters.
6325
Georg Brandl5cb76c12007-03-21 09:00:39 +00006326- Patch #1682205: a TypeError while unpacking an iterable is no longer

6330
Guido van Rossum143b5642007-03-23 04:58:42 +00006331- Bug #1683368: The object.__init__() and object.__new__() methods are
6332 now stricter in rejecting excess arguments. The only time when
6333 either allows excess arguments is when it is not overridden and the
6334 other one is. For backwards compatibility, when both are
6335 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006336 warning later). Also, type.__init__() insists on the same signature
6337 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6340 object to complex using its __complex__() method before falling back
6341 to the __float__() method. Therefore, the functions in the cmath
6342 module now can operate on objects that define a __complex__()
6343 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006344
Georg Brandl3ee81df2008-05-17 18:14:43 +00006345- Patch #1623563: allow __class__ assignment for classes with
6346 __slots__. The old and the new class are still required to have the
6347 same slot names.

6354 its type.

6360
Georg Brandl7b9c5552007-03-12 14:30:05 +00006361- Bug #1678647: write a newline after printing an exception in any
6362 case, even when converting the value to a string failed.
6363
Georg Brandl871f1bc2007-03-12 13:17:36 +00006364- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006365 its argument, if it exists. If not, it will work like before. This
6366 allows customizing the output of dir() in the presence of a
6367 __getattr__().

6371
Georg Brandl3ee81df2008-05-17 18:14:43 +00006372- Patch #1675981: remove unreachable code from ``type.__new__()``

6376 parthensized forms. This means complex(repr(x)) now works instead of
6377 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006378
Georg Brandlaa2321b2007-03-07 00:40:28 +00006379- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006380 makes the filenames the warning module prints much more sensible
6381 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006382

Georg Brandl0fca97a2007-03-05 22:28:08 +00006394- Patch #1674228: when assigning a slice (old-style), check for the
6395 sq_ass_slice instead of the sq_slice slot.
6396
Georg Brandl3ee81df2008-05-17 18:14:43 +00006397- When printing an unraisable error, don't print exceptions. before
6398 the name. This duplicates the behavior whening normally printing
6399 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006932 AttributeError instead of an IOError when the server's response
6933 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006934

Georg Brandl3ee81df2008-05-17 18:14:43 +00006950- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006967 are set for invalid interpolation sequences that would lead to
6968 errors on reading back those values.

7011 returned string up to the first NUL character.

7024 TestCase and TestSuite subclasses (not instances) are no longer
7025 accepted in TestSuite.addTest(). This should cause no
7026 incompatibility since it never made sense with ordinary subclasses
7027 -- the failure just occurred later, with a more cumbersome
7028 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007417 time so that opening a database previously created with the DB_DUP
7418 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7419 opens. Specifically: dictionary assignment to a DB object will
7420 replace all values for a given key when the database allows
7421 duplicate values. DB users should use DB.put(k, v) when they want
7422 to store duplicates; not DB[k] = v.

7431 behavior of quoting dots if they are the second character of any
7432 line.

7778 of w# format code incorrectly truncated the length to an int, even
7779 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7780 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007810- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7811 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
