96
Ned Deily87e82bb2011-06-28 19:52:59 -070097- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
98 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
99 interpreter process. This could cause failures in non-Distutils subprocesses
100 and was unreliable since tests or user programs could modify the interpreter
101 environment after Distutils set it. Instead, have Distutils set the the
102 deployment target only in the environment of each build subprocess. It is
103 still possible to globally override the default by setting
104 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
105 greater or equal to the default value, the value with which the interpreter
106 was built.
107
Raymond Hettinger2c316a32011-06-25 17:14:53 +0200108- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

112 Kitada.

115 times without error, and _ProxyFile now closes the wrapped file.
116
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200117- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
118 connection if its getresponse() method fails with a socket error. Patch
119 written by Ezio Melotti.
120
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500121- Issue #9284: Allow inspect.findsource() to find the source of doctest
122 functions.
123

133
Barry Warsawc5643282011-07-19 17:06:30 -0400134- sys.setcheckinterval() now updates the current ticker count as well as
135 updating the check interval, so if the user decreases the check interval,
136 the ticker doesn't have to wind down to zero from the old starting point
137 before the new interval takes effect. And if the user increases the
138 interval, it makes sure the new limit takes effect right away rather have an
139 early task switch before recognizing the new interval.

Victor Stinner776e69b2011-06-01 01:03:00 +0200141- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

995 This prevents user-created self-referencing ordered dictionaries from
996 becoming permanently uncollectable GC garbage. The downside is that
997 removing __del__ means that the internal doubly-linked list has to wait for
998 GC collection rather than freeing memory immediately when the refcnt drops
999 to zero.

1460 of the number of bytes specified by the start byte.
1461 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1462 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1474 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001844- Issue #7301: Add environment variable $PYTHONWARNINGS.
1845
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001846- Issue #8329: Don't return the same lists from select.select when no fds are
1847 changed.
1848
Georg Brandlfee0f442010-05-22 21:26:21 +00001849- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001850 on 64-bit machines. The shift count for either left or right shift is
1851 permitted to be up to sys.maxsize.

1858
Georg Brandlfee0f442010-05-22 21:26:21 +00001859- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1860 with a non-empty format string. This is an effort to future-proof user
1861 code. If a derived class does not currently implement __format__ but later
1862 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001863 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001864 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001897- Issue #8257: The Decimal construct now accepts a float instance directly,
1898 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001899

1902
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001903- collections.Counter() now supports a subtract() method.
1904
Georg Brandlfee0f442010-05-22 21:26:21 +00001905- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001914- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1915 InvalidOperation instead of returning False. (Comparisons involving a quiet
1916 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1917 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001918
Georg Brandlfee0f442010-05-22 21:26:21 +00001919- Issue #2531: Comparison operations between floats and Decimal instances now
1920 return a result based on the numeric values of the operands; previously they
1921 returned an arbitrary result based on the relative ordering of id(float) and
1922 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001923
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001924- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001925 argument `-` which tells it to read files to compile from stdin. Each line is
1926 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00001932- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1933 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001934 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001936- Comparisons using one of <, <=, >, >= between a complex instance and a
1937 Fractions instance now raise TypeError instead of returning True/False. This
1938 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1939 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002301- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2302 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2303 returning NULL. The macro now returns a statically allocated empty string
2304 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00002349- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002350 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002351 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002356- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002357 file position when calling `truncate()`. It would previously change the file
2358 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002359 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2360
Georg Brandlba83f822010-03-14 09:50:54 +00002361- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2362 class used to represent files stored inside an archive. The new
2363 implementation is significantly faster and can be wrapped in a
2364 ``io.BufferedReader`` object for more speedups. It also solves an issue
2365 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002376- Issue #7748: Since unicode values are supported for some metadata options in
2377 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2378 encoded string for them. This ensures that the upload and register commands
2379 send the correct values to PyPI without any error.

2454-----------------
2455
Georg Brandlba83f822010-03-14 09:50:54 +00002456- The ``__complex__()`` method is now looked up on the class of instances to
2457 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002458
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002459- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2460 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2461
Mark Dickinson1b34d252010-01-01 17:27:30 +00002462- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002463 DeprecationWarning when passed a float argument where an integer was expected.
2464 These functions and methods now raise TypeError instead. The majority of the
2465 effects of this change are in the extension modules, but some core functions
2466 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2467 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002468

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002477- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2478 used to drop the time part of the result.
2479
Georg Brandlba83f822010-03-14 09:50:54 +00002480- Issue #1811: Improve accuracy and cross-platform consistency for true division
2481 of integers: the result of a/b is now correctly rounded for ints a and b (at
2482 least on IEEE 754 platforms), and in particular does not depend on the
2483 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002484
Georg Brandlba83f822010-03-14 09:50:54 +00002485- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2486 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2487 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002488

Ronald Oussoren92919a62009-12-24 13:30:58 +00002490 executables on OSX.
2491
Georg Brandlba83f822010-03-14 09:50:54 +00002492 These executables now work properly with the arch(1) command: ``arch -ppc
2493 python`` will start a universal binary version of python in PPC mode (unlike
2494 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002495
Georg Brandlba83f822010-03-14 09:50:54 +00002496- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2497 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00002516- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002517 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2518 alternative to cPickle if you care about performance. Patch by Florent

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002553- Issue #7349: Make methods of file objects in the io module accept None as an
2554 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2555 the same as passing no argument.
2556
Georg Brandlba83f822010-03-14 09:50:54 +00002557- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00002579- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2580 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2581 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2582 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00002650- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2651 decimal string that's guaranteed to round back to x under correct rounding
2652 (with round-half-to-even rounding mode). Previously it gave a string based on
2653 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2654 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2655 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002656
Georg Brandlba83f822010-03-14 09:50:54 +00002657- Issue #7117: On almost all platforms: float-to-string and string-to-float
2658 conversions within Python are now correctly rounded. Places these conversions
2659 occur include: str for floats and complex numbers; the float and complex
2660 constructors; old-style and new-style numeric formatting; serialization and
2661 deserialization of floats and complex numbers using marshal, pickle and json;
2662 parsing of float and imaginary literals in Python code; Decimal-to-float
2663 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002664
Georg Brandlba83f822010-03-14 09:50:54 +00002665 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2666 providing correctly-rounded strtod and dtoa C functions. This code is
2667 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2668 the C compiler. There may be a small number of platforms on which correct
2669 operation of this code cannot be guaranteed, so the code is not used: notably,
2670 this applies to platforms where the C double format is not IEEE 754 binary64,
2671 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2672 and Python's configure script is unable to determine how to change the FPU
2673 precision. On these platforms conversions use the platform strtod and dtoa,
2674 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002675
Georg Brandlba83f822010-03-14 09:50:54 +00002676- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2677 uses the correctly-rounded string <-> float conversions described above (when
2678 available), and so produces correctly rounded results that will display nicely
2679 under the float repr. There are two related small changes: (1) round now
2680 accepts any class with an ``__index__()`` method for its second argument (but
2681 no longer accepts floats for the second argument), and (2) an excessively
2682 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2683 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002901 untrackable objects are not tracked by the garbage collector. This can reduce
2902 the size of collections and therefore the garbage collection overhead on
2903 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002909- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2910 internal representation of integers, for performance reasons. Base 2**30 is
2911 enabled by default on 64-bit machines. Add --enable-big-digits option to
2912 configure, which overrides the default. Add sys.long_info structseq to
2913 provide information about the internal format.

2944
Georg Brandl29c6a282009-04-05 20:23:13 +00002945- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002946 were suppressing all exceptions. These include list(), filter(), map(),

2948
Benjamin Peterson596d3062009-01-19 15:42:23 +00002949- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002957- Issue #4935: The overflow checking code in the expandtabs() method common to
2958 str, bytes and bytearray could be optimized away by the compiler, letting the
2959 interpreter segfault instead of raising an error.

2969 collecting the oldest generation) so that allocating lots of objects without
2970 destroying them does not show quadratic performance. Based on a proposal by

2975
Georg Brandlba83f822010-03-14 09:50:54 +00002976- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2977 existing .py counterpart, override the co_filename attributes of all code
2978 objects if the original filename is obsolete (which can happen if the file has
2979 been renamed, moved, or if it is accessed through different paths). Patch by

3020 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3021 instances. On a typical machine this saves 3 bytes of memory (on average) per

3033
Georg Brandlba83f822010-03-14 09:50:54 +00003034- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3035 file objects with closefd=False. The file descriptor is still kept open but
3036 the file object behaves like a closed file. The ``FileIO`` object also got a
3037 new readonly attribute ``closefd``.

3056
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003057- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003058 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003060- On windows, ``os.chdir()`` given unicode was not working if
3061 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3062 this code path is really executed because I cannot move to such directory on
3063 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003064
Georg Brandlba83f822010-03-14 09:50:54 +00003065- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3066 element is temporarily replaced with an equivalent frozenset. But the
3067 eventual KeyError would always report the empty ``frozenset()`` as the missing
3068 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003088- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3089 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3090 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3091 of using the replace error handler in PyUnicode_DecodeUTF8().
3092
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003093- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003096- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3098 gives improved memory leak detection when running under Valgrind, while taking
3099 advantage of pymalloc at other times.

4265 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4266 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4267 neither __int__ nor __long__, TypeError used to be raised (with a
4268 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4269 struct.error in other cases.

4272 argument with an __int__ method can be packed, but use of this feature
4273 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004466- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4468 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4469 ``printf`` function, whereas PyString_FromFormat has an independent
4470 implementation and uses "%zd" on all platforms for size_t values.

4495 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4496 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004567 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4568 for catch_warnings() also led to an improvement in the raising of a
4569 DeprecationWarning related to warnings.warn_explicit().
4570

4593
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004594- Issue #2975: When compiling several extension modules with Visual Studio 2008
4595 from the same python interpreter, some environment variables would grow
4596 without limit.
4597
Benjamin Peterson37346b22008-08-23 20:27:43 +00004598- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004635What's New in Python 2.6 beta 3?
4636================================
4637
Barry Warsaw07a4a382008-08-21 01:15:08 +00004638*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004639
4640Core and Builtins
4641-----------------
4642
Guido van Rossumf8402962008-08-20 15:01:50 +00004643- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4644 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4645 extensions do not automatically benefit from the class attribute
4646 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4647 to their tp_flags field if they care. This is a backwards
4648 compatibility feature; in 3.0, all types will use the cache by
4649 default.
4650
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004651- Keyword arguments can now follow starred arguments. (``f(a, *args,
4652 keyword=23)`` is now valid syntax.)
4653
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004654- ctypes function pointers that are COM methods have a boolean True
4655 value again.
4656
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004657- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4658 by denying s# to parse objects that have a releasebuffer procedure,
4659 and introducing s*.
4660
Georg Brandl1e13ea92008-08-11 09:07:59 +00004661- Issue #3537: Fix an assertion failure when an empty but presized dict
4662 object was stored in the freelist.
4663
Mark Dickinsonb6467572008-08-04 21:30:09 +00004664- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4665 ValueError consistently across platforms.
4666
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004667- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4668 (64bit Unix, for example), unichr() would truncate its argument and return
4669 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4670
Neal Norwitze7d8be82008-07-31 17:17:14 +00004671- Apply security patches from Apple.
4672
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004673- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4674 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4675
Antoine Pitrou92f82162008-07-25 22:22:08 +00004676- Issue #1819: function calls with several named parameters are now on
4677 average 35% faster (as measured by pybench).
4678
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004679- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4680 the python debugger steps into a class statement: the free variables (local
4681 variables defined in an outer scope) would be deleted from the outer scope.
4682
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004683- Issue #2620: Overflow checking when allocating or reallocating memory
4684 was not always being done properly in some python types and extension
4685 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4686 all been updated to perform better checks and places in the code that
4687 would previously leak memory on the error path when such an allocation
4688 failed have been fixed.

4694
Benjamin Petersone977ad42008-08-20 01:42:01 +00004695- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4696 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4697
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004698- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4699 version reported by these tools does not necessarily follow the python
4700 version numbering scheme, so the module is less strict when parsing it.
4701
Nick Coghlanf70385a2008-08-18 12:42:46 +00004702- Issue #2235: Added Py3k warnings for types which will become unhashable
4703 under the stricter __hash__ inheritance rules in 3.0. Several types
4704 which did not meet the rules for hash invariants and were already
4705 unhashable in 3.0 have now been explicitly flagged as unhashable in
4706 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4707 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4708
Brett Cannon88f801d2008-08-18 00:46:22 +00004709- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4717
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004718- Issue #3575: Incremental decoder's decode function now takes bytearray
4719 by using 's*' instead of 't#'.
4720
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004721- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004722 fails unicode conversion on 2nd parameter. (windows only)
4723
Georg Brandl222e2082010-08-01 22:27:39 +00004724- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004725 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00004728 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004729
Facundo Batistaeb90b782008-08-16 14:44:07 +00004730- Issue #2776: fixed small issue when handling an URL with double slash
4731 after a 302 response in the case of not going through a proxy.
4732
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004733- Issue #2676: in the email package, content-type parsing was hanging on
4734 pathological input because of quadratic or exponential behaviour of a
4735 regular expression.
4736
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004737- Issue #3476: binary buffered reading through the new "io" library is now
4738 thread-safe.
4739
Brett Cannonbf3157b2008-08-14 05:00:03 +00004740- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4741 since mimetools itself is deprecated. Because modules are cached, all
4742 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4743
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004744- Issue #3134: shutil referenced undefined WindowsError symbol.
4745
Robert Schuppenies14646332008-08-10 11:01:53 +00004746- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4747 menu entries were not deleted.
4748
Brett Cannon83e81842008-08-09 23:30:55 +00004749- Copied the implementation of reduce() to _functools.reduce() to have a
4750 version that did not raise a DeprecationWarning under -3.
4751
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004752- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4753 a MemoryError rather than silently stop the iteration.
4754
Guido van Rossum59ce9012008-08-09 14:55:34 +00004755- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4756 to _sre.compile() will now be rejected. This should not affect anybody
4757 since the re.compile() function never generates invalid re-bytecode.
4758
Skip Montanaroa032bf42008-08-08 22:52:51 +00004759- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

4761 it wasn't initialized during instantiation.
4762
Brett Cannon3aa2a492008-08-06 22:28:09 +00004763- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4764 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00004778 asking for a specific length. This problem only affected files opened
4779 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004780

4825 regarding lack of coverage of new-style classes have also been
4826 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004829What's New in Python 2.6 beta 2?
4830================================
4831
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004832*Release date: 17-Jul-2008*
4833
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004834Core and Builtins
4835-----------------
4836
Georg Brandl3e483f62008-07-16 22:57:41 +00004837- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4838 its methods now allow for items objects that can be converted to
4839 an integer using operator.index().
4840
Mark Dickinson64b7e502008-07-16 09:40:03 +00004841- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4842 produced a ValueError instead of giving the correct float.
4843
Eric Smitha5fa5a22008-07-16 00:11:49 +00004844- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4845 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4846
Mark Dickinson7103aa42008-07-15 19:08:33 +00004847- Issue #3008: the float type has a new instance method 'float.hex'
4848 and a new class method 'float.fromhex' to convert floating-point
4849 numbers to and from hexadecimal strings, respectively.
4850
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004851- Issue #2235: __hash__ is once again inherited by default. To allow
4852 collections.Hashable to remain meaningful in the presence of the
4853 default hash implementation (object.__hash__), it is now possible
4854 to explicit block inheritance of hash by setting __hash__=None at
4855 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4856 level.
4857
Nick Coghlanb028f502008-07-13 14:52:36 +00004858- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4859 the parent module cannot be found while performing an absolute import.
4860 This means that an incorrectly defined __package__ attribute will
4861 now only prevent relative imports in that module rather than causing
4862 all imports from that module to fail.
4863
Nick Coghlan14ff9942008-07-08 14:21:42 +00004864- Issue #2517: Allow unicode messages in Exceptions again by correctly
4865 bypassing the instance dictionary when looking up __unicode__ on
4866 new-style classes.
4867
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004868- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4869 set to a custom object whose write() method happens to install
4870 another file in sys.stdout.
4871
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004872- Issue #3088: Corrected a race condition in classes derived from
4873 threading.local: the first member set by a thread could be saved in
4874 another thread's dictionary.
4875
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004876- Issue #3004: Minor change to slice.indices(): the start and stop
4877 arguments are now treated identically, making the behaviour easier
4878 to describe and understand. For example, slice(None, -10,
4879 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4880 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4881 10, -1).
4882
Georg Brandl278fc502008-07-19 12:46:12 +00004883- Issue #3219: Calling a function with repeated keyword arguments,
4884 f(a=2, a=23), would not cause a syntax error. This was a regression
4885 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004886
Georg Brandl278fc502008-07-19 12:46:12 +00004887- Issue #2862: Make int and float freelist management consistent with
4888 other freelists. Changes their CompactFreeList apis into
4889 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004890
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004891Library
4892-------
4893
Thomas Heller57adf222008-08-14 19:10:48 +00004894- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4895 api functions without holding the GIL, which could lead to a fatal
4896 error when they failed.
4897
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004898- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4899

4905
Jesse Noller13e9d582008-07-16 14:32:36 +00004906- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4907 ForkingPickler.register() to resolve conflict with ctypes.
4908
Vinay Sajip51e65192008-07-18 09:01:10 +00004909- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004910
Thomas Heller880f5292008-07-15 19:39:38 +00004911- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4912 a valid dlerror() message.
4913
Thomas Heller2bad6572008-07-15 17:19:50 +00004914- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4915 incomplete structure was created.
4916
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004917- Issue #3339: dummy_thread.acquire() should not return None.
4918
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004919- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4920
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004921- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004922
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004923- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4924 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004925 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004926 content-length. The problem had been corrected in the 2.4 branch, but never
4927 merged into trunk.
4928
Georg Brandle78fbcc2008-07-05 10:13:36 +00004929- Issue #2663: add filtering capability to shutil.copytree().
4930

4932
4933- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4934
4935- Issue #1746: Correct handling of zipfile archive comments (previously
4936 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004937 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004938
Vinay Sajip51e65192008-07-18 09:01:10 +00004939- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004940 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004941
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004942- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4943 handling is now the same as that of other special attributes like __name__).
4944
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004945- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4946 removal in Python 3.0 in favor of urllib2.urlopen().

4954
Gregory P. Smithc4691ec2008-07-07 05:09:12 +00004955- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
4956 redundant ":443" port number designation when the connection is using the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005397- Issue #1631171: Re-implement the 'warnings' module in C (the
5398 original Python code has been kept as backup). This will allow for
5399 using the 'warning's machinery in such places as the parser where
5400 use of pure Python code is not possible. Both the ``showarning()``
5401 and ``formatwarning()`` gain an optional 'line' argument which is
5402 not called by default for backwards-compatibility reasons. Setting
5403 ``warnings.showwarning()`` to an implementation that lacks support
5404 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005467- Issue #2550: The approach used by client/server code for obtaining
5468 ports to listen on in network-oriented tests has been refined in an
5469 effort to facilitate running multiple instances of the entire
5470 regression test suite in parallel without issue.
5471 test_support.bind_port() has been fixed such that it will always
5472 return a unique port -- which wasn't always the case with the
5473 previous implementation, especially if socket options had been set
5474 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5475 new implementation of bind_port() will actually raise an exception
5476 if it is passed an AF_INET/SOCK_STREAM socket with either the
5477 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5478 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5479 the socket it's been passed. This currently only applies to
5480 Windows. This option prevents any other sockets from binding to the
5481 host/port we've bound to, thus removing the possibility of the
5482 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5483 when a second SOCK_STREAM socket binds and accepts to a host/port
5484 that's already been bound by another socket. The optional preferred
5485 port parameter to bind_port() has been removed. Under no
5486 circumstances should tests be hard coding ports!
5487
5488 test_support.find_unused_port() has also been introduced, which will
5489 pass a temporary socket object to bind_port() in order to obtain an
5490 unused port. The temporary socket object is then closed and
5491 deleted, and the port is returned. This method should only be used
5492 for obtaining an unused port in order to pass to an external program
5493 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5494 a parameter to a server-oriented class that doesn't give you direct
5495 access to the underlying socket used.
5496
5497 Finally, test_support.HOST has been introduced, which should be used
5498 for the host argument of any relevant socket calls (i.e. bind and
5499 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005500
5501 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005502 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

5663 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00005664 platform.machine() and platform.processor() will report this
5665 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00005786- Added the future_builtins module, which contains hex() and oct().
5787 These are the PEP 3127 version of these functions, designed to be
5788 compatible with the hex() and oct() builtins from Python 3.0. They
5789 differ slightly in their output formats from the existing, unchanged
5790 Python 2.6 builtins. The expected usage of the future_builtins
5791 module is:
5792 from future_builtins import hex, oct
5793
Eric Smith7ef40bf2008-02-20 23:34:22 +00005794- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5795 exponents for exponents with absolute value < 100. Follows C99
5796 standard. This is a change on Windows, which would use 3 digits.
5797 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5798 so that any alterations it does to the resulting string will be
5799 available in stringlib/formatter.h (for float.__format__).
5800
Eric Smith5a3c1352008-02-19 13:21:56 +00005801- Implemented PEP 3101, Advanced String Formatting. This adds a new
5802 builtin format(); a format() method for str and unicode; a
5803 __format__() method to object, str, unicode, int, long, float, and
5804 datetime; the class string.Formatter; and the C API
5805 PyObject_Format().
5806
Georg Brandl3ee81df2008-05-17 18:14:43 +00005807- Fixed several potential crashes, all caused by specially crafted
5808 __del__ methods exploiting objects in temporarily inconsistent
5809 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005810
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005811- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005812 prevent a possible crash: an Abstract Base Class would try to access
5813 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005814

Georg Brandl3ee81df2008-05-17 18:14:43 +00005818- Clear all free lists during a gc.collect() of the highest generation
5819 in order to allow pymalloc to free more arenas. Python may give back
5820 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005821
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- Issue #2045: Fix an infinite recursion triggered when printing a
5823 subclass of collections.defaultdict, if its default_factory is set
5824 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005825
Christian Heimesf75dbef2008-02-08 00:11:31 +00005826- Fixed a minor memory leak in dictobject.c. The content of the free
5827 list was not freed on interpreter shutdown.
5828
Georg Brandl21e99f42010-03-07 15:23:59 +00005829- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005831
Georg Brandl3ee81df2008-05-17 18:14:43 +00005832- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5833 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005834 to compact the internal free lists of pre-allocted ints and floats.
5835
Georg Brandl3ee81df2008-05-17 18:14:43 +00005836- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5837 calls. Python expected the return type int but the fork familie
5838 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005839
Georg Brandl3ee81df2008-05-17 18:14:43 +00005840- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005852- Patch #1473257: generator objects gain a gi_code attribute. This is
5853 the same object as the func_code attribute of the function that
5854 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005855
Georg Brandl3ee81df2008-05-17 18:14:43 +00005856- Issue #1920: "while 0" statements were completely removed by the
5857 compiler, even in the presence of an "else" clause, which is
5858 supposed to be run when the condition is false. Now the compiler
5859 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005860
Guido van Rossumeead05f2008-01-24 18:21:02 +00005861- A few crashers fixed: weakref_in_del.py (issue #1377858);
5862 loosing_dict_ref.py (issue #1303614, test67.py);
5863 borrowed_ref_[34].py (not in tracker).
5864

5868
Georg Brandl3ee81df2008-05-17 18:14:43 +00005869- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005870 several extension methods and modules do not work without unicode
5871 support.
5872
Georg Brandl26543b12008-01-21 18:36:51 +00005873- Issue #1882: when compiling code from a string, encoding cookies in the
5874 second line of code were not always recognized correctly.
5875
Georg Brandl14404b62008-01-19 19:27:05 +00005876- Issue #1679: "0x" was taken as a valid integer literal.
5877
Georg Brandl6caad7d2008-01-26 14:19:22 +00005878- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005879 added.
5880
Christian Heimesc94e2b52008-01-14 04:13:37 +00005881- sys.float_info / PyFloat_GetInfo: The floating point information
5882 object was converted from a dict to a specialized structseq object.
5883
Georg Brandl3ee81df2008-05-17 18:14:43 +00005884- Patch #1816: Added sys.flags structseq. It exposes the status of
5885 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005886
Georg Brandl3ee81df2008-05-17 18:14:43 +00005887- Objects/structseq.c: Implemented new structseq representation. The

5898
Georg Brandl3ee81df2008-05-17 18:14:43 +00005899- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5900 envvar and sys.dont_write_bytecode attribute. All these can be set
5901 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005902
Georg Brandl3ee81df2008-05-17 18:14:43 +00005903- Improve some exception messages when Windows fails to load an
5904 extension module. Now we get for example '%1 is not a valid Win32
5905 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005912- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005913 and INF. float("nan"), float("inf") and float("-inf") now work on
5914 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005916- Compiler now generates simpler and faster code for dictionary
5917 literals. The oparg for BUILD_MAP now indicates an estimated
5918 dictionary size. There is a new opcode, STORE_MAP, for adding
5919 entries to the dictionary.

5949 file can now be directly executed by passing their name to the
5950 interpreter. The directory/zipfile is automatically inserted as the
5951 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005953- Issue #1265: Fix a problem with sys.settrace, if the tracing
5954 function uses a generator expression when at the same time the
5955 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005956
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005957- sets and frozensets now have an isdisjoint() method.

5962
Georg Brandl21e99f42010-03-07 15:23:59 +00005963- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005964 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5965 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005966
Georg Brandl3ee81df2008-05-17 18:14:43 +00005967- Issue #1686386: Tuple's tp_repr did not take into account the
5968 possibility of having a self-referential tuple, which is possible
5969 from C code. Nor did object's tp_str consider that a type's tp_str
5970 could do something that could lead to an inifinite recursion.
5971 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5972 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005973
Georg Brandl3ee81df2008-05-17 18:14:43 +00005974- Issue #1164: It was possible to trigger deadlock when using the
5975 'print' statement to write to a file since the GIL was not released
5976 as needed. Now PyObject_Print() does the right thing along with
5977 various tp_print implementations of the built-in types and those in
5978 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005979
Georg Brandl3ee81df2008-05-17 18:14:43 +00005980- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00005986
Brett Cannon1e534b52007-09-07 04:18:30 +00005987- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005988 PyObject_Call() never calling back out to Python code to trigger
5989 recursion depth updates/checks. Required the creation of a static
5990 RuntimeError instance in case normalizing an exception put the
5991 recursion check value past its limit. Fixes crashers
5992 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005993

Neal Norwitz0ac60192007-05-27 04:08:54 +00006007- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006008 __*__ attributes. (Some already existed, e.g., __doc__ and
6009 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006010
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006011- Add -3 option to the interpreter to warn about features that are
6012 deprecated and will be changed/removed in Python 3.0.
6013
Georg Brandl2134e752007-05-21 20:34:16 +00006014- Patch #1686487: you can now pass any mapping after '**' in function
6015 calls.
6016
Collin Winter62903052007-05-18 23:11:24 +00006017- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006018 "except E as target:". This is to provide forwards compatibility
6019 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006026- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006027 setting a plain string, ie don't expand to single letter identifiers.
6028
Raymond Hettinger13936692007-04-11 18:40:58 +00006029- Request #1191699: Slices can now be pickled.
6030
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006031- Request #1193128: str.translate() now allows a None argument for
6032 translations that only remove characters without re-mapping the
6033 remaining characters.
6034
Georg Brandl5cb76c12007-03-21 09:00:39 +00006035- Patch #1682205: a TypeError while unpacking an iterable is no longer

6039
Guido van Rossum143b5642007-03-23 04:58:42 +00006040- Bug #1683368: The object.__init__() and object.__new__() methods are
6041 now stricter in rejecting excess arguments. The only time when
6042 either allows excess arguments is when it is not overridden and the
6043 other one is. For backwards compatibility, when both are
6044 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006045 warning later). Also, type.__init__() insists on the same signature
6046 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006047
Georg Brandl3ee81df2008-05-17 18:14:43 +00006048- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6049 object to complex using its __complex__() method before falling back
6050 to the __float__() method. Therefore, the functions in the cmath
6051 module now can operate on objects that define a __complex__()
6052 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006053
Georg Brandl3ee81df2008-05-17 18:14:43 +00006054- Patch #1623563: allow __class__ assignment for classes with

6056 same slot names.

6063 its type.

6069
Georg Brandl7b9c5552007-03-12 14:30:05 +00006070- Bug #1678647: write a newline after printing an exception in any
6071 case, even when converting the value to a string failed.
6072
Georg Brandl871f1bc2007-03-12 13:17:36 +00006073- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006074 its argument, if it exists. If not, it will work like before. This
6075 allows customizing the output of dir() in the presence of a
6076 __getattr__().

6080
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081- Patch #1675981: remove unreachable code from ``type.__new__()``

6085 parthensized forms. This means complex(repr(x)) now works instead of
6086 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006087
Georg Brandlaa2321b2007-03-07 00:40:28 +00006088- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006089 makes the filenames the warning module prints much more sensible
6090 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006103- Patch #1674228: when assigning a slice (old-style), check for the
6104 sq_ass_slice instead of the sq_slice slot.
6105
Georg Brandl3ee81df2008-05-17 18:14:43 +00006106- When printing an unraisable error, don't print exceptions. before
6107 the name. This duplicates the behavior whening normally printing
6108 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006641 AttributeError instead of an IOError when the server's response
6642 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006643

Georg Brandl3ee81df2008-05-17 18:14:43 +00006659- Patch #1530482: add pydoc.render_doc() which returns the

6674
Georg Brandl92a6bae2007-03-13 17:43:32 +00006675- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006676 are set for invalid interpolation sequences that would lead to
6677 errors on reading back those values.

6720 returned string up to the first NUL character.

6731
Georg Brandl3ee81df2008-05-17 18:14:43 +00006732- unittest now verifies more of its assumptions. In particular,
6733 TestCase and TestSuite subclasses (not instances) are no longer
6734 accepted in TestSuite.addTest(). This should cause no
6735 incompatibility since it never made sense with ordinary subclasses
6736 -- the failure just occurred later, with a more cumbersome
6737 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007126 time so that opening a database previously created with the DB_DUP
7127 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7128 opens. Specifically: dictionary assignment to a DB object will
7129 replace all values for a given key when the database allows
7130 duplicate values. DB users should use DB.put(k, v) when they want
7131 to store duplicates; not DB[k] = v.

7138 characters with ASCII value less than 32. Also, it correctly quotes
7139 dots only if they occur on a single line, as opposed to the previous
7140 behavior of quoting dots if they are the second character of any
7141 line.

7487 of w# format code incorrectly truncated the length to an int, even
7488 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7489 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007519- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7520 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
