435 This prevents user-created self-referencing ordered dictionaries from
436 becoming permanently uncollectable GC garbage. The downside is that

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001258 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001283- Issue #7301: Add environment variable $PYTHONWARNINGS.
1284
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001285- Issue #8329: Don't return the same lists from select.select when no fds are
1286 changed.
1287
Georg Brandlfee0f442010-05-22 21:26:21 +00001288- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001289 on 64-bit machines. The shift count for either left or right shift is
1290 permitted to be up to sys.maxsize.
1291
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001292- Ensure that tokenization of identifiers is not affected by locale.

1297
Georg Brandlfee0f442010-05-22 21:26:21 +00001298- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1299 with a non-empty format string. This is an effort to future-proof user
1300 code. If a derived class does not currently implement __format__ but later
1301 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001302 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001303 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001336- Issue #8257: The Decimal construct now accepts a float instance directly,
1337 converting that float to a Decimal of equal value:

Georg Brandlfee0f442010-05-22 21:26:21 +00001353- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1354 InvalidOperation instead of returning False. (Comparisons involving a quiet
1355 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1356 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001357
Georg Brandlfee0f442010-05-22 21:26:21 +00001358- Issue #2531: Comparison operations between floats and Decimal instances now
1359 return a result based on the numeric values of the operands; previously they
1360 returned an arbitrary result based on the relative ordering of id(float) and
1361 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001363- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001364 argument `-` which tells it to read files to compile from stdin. Each line is
1365 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001375- Comparisons using one of <, <=, >, >= between a complex instance and a
1376 Fractions instance now raise TypeError instead of returning True/False. This
1377 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1378 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001735- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1736 and add the additional members returned in an OSVERSIONINFOEX structure. The
1737 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001740- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1741 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1742 returning NULL. The macro now returns a statically allocated empty string
1743 instead.

1753 strings,
1754 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1755 numeric strings corresponding to subnormal values,
1756 (3) a memory leak for some values large enough to cause overflow, and
1757 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001788- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001789 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001790 Also, raise ValueError rather than TypeError when an unknown TIPC address
1791 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001795- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001796 file position when calling `truncate()`. It would previously change the file
1797 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001798 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1799
Georg Brandlba83f822010-03-14 09:50:54 +00001800- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1801 class used to represent files stored inside an archive. The new
1802 implementation is significantly faster and can be wrapped in a
1803 ``io.BufferedReader`` object for more speedups. It also solves an issue
1804 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001815- Issue #7748: Since unicode values are supported for some metadata options in
1816 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1817 encoded string for them. This ensures that the upload and register commands
1818 send the correct values to PyPI without any error.

1893-----------------
1894
Georg Brandlba83f822010-03-14 09:50:54 +00001895- The ``__complex__()`` method is now looked up on the class of instances to
1896 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001897
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001898- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1899 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1900
Mark Dickinson1b34d252010-01-01 17:27:30 +00001901- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001902 DeprecationWarning when passed a float argument where an integer was expected.
1903 These functions and methods now raise TypeError instead. The majority of the
1904 effects of this change are in the extension modules, but some core functions
1905 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1906 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001916- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1917 used to drop the time part of the result.
1918
Georg Brandlba83f822010-03-14 09:50:54 +00001919- Issue #1811: Improve accuracy and cross-platform consistency for true division
1920 of integers: the result of a/b is now correctly rounded for ints a and b (at
1921 least on IEEE 754 platforms), and in particular does not depend on the
1922 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001923
Georg Brandlba83f822010-03-14 09:50:54 +00001924- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1925 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1926 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001927

Ronald Oussoren92919a62009-12-24 13:30:58 +00001929 executables on OSX.
1930
Georg Brandlba83f822010-03-14 09:50:54 +00001931 These executables now work properly with the arch(1) command: ``arch -ppc
1932 python`` will start a universal binary version of python in PPC mode (unlike
1933 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001934

Georg Brandlba83f822010-03-14 09:50:54 +00001956 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1957 alternative to cPickle if you care about performance. Patch by Florent

1993 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1994 the same as passing no argument.
1995
Georg Brandlba83f822010-03-14 09:50:54 +00001996- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

2020 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

Georg Brandlba83f822010-03-14 09:50:54 +00002089- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2090 decimal string that's guaranteed to round back to x under correct rounding
2091 (with round-half-to-even rounding mode). Previously it gave a string based on
2092 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2093 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2094 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002095
Georg Brandlba83f822010-03-14 09:50:54 +00002096- Issue #7117: On almost all platforms: float-to-string and string-to-float
2097 conversions within Python are now correctly rounded. Places these conversions
2098 occur include: str for floats and complex numbers; the float and complex
2099 constructors; old-style and new-style numeric formatting; serialization and
2100 deserialization of floats and complex numbers using marshal, pickle and json;
2101 parsing of float and imaginary literals in Python code; Decimal-to-float
2102 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002103
Georg Brandlba83f822010-03-14 09:50:54 +00002104 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2105 providing correctly-rounded strtod and dtoa C functions. This code is
2106 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2107 the C compiler. There may be a small number of platforms on which correct
2108 operation of this code cannot be guaranteed, so the code is not used: notably,
2109 this applies to platforms where the C double format is not IEEE 754 binary64,
2110 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2111 and Python's configure script is unable to determine how to change the FPU
2112 precision. On these platforms conversions use the platform strtod and dtoa,
2113 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002114
Georg Brandlba83f822010-03-14 09:50:54 +00002115- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2116 uses the correctly-rounded string <-> float conversions described above (when
2117 available), and so produces correctly rounded results that will display nicely
2118 under the float repr. There are two related small changes: (1) round now
2119 accepts any class with an ``__index__()`` method for its second argument (but
2120 no longer accepts floats for the second argument), and (2) an excessively
2121 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2122 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002340 untrackable objects are not tracked by the garbage collector. This can reduce
2341 the size of collections and therefore the garbage collection overhead on
2342 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002348- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2349 internal representation of integers, for performance reasons. Base 2**30 is
2350 enabled by default on 64-bit machines. Add --enable-big-digits option to
2351 configure, which overrides the default. Add sys.long_info structseq to
2352 provide information about the internal format.

2383
Georg Brandl29c6a282009-04-05 20:23:13 +00002384- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002385 were suppressing all exceptions. These include list(), filter(), map(),

2387
Benjamin Peterson596d3062009-01-19 15:42:23 +00002388- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002396- Issue #4935: The overflow checking code in the expandtabs() method common to
2397 str, bytes and bytearray could be optimized away by the compiler, letting the
2398 interpreter segfault instead of raising an error.

2414
Georg Brandlba83f822010-03-14 09:50:54 +00002415- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2416 existing .py counterpart, override the co_filename attributes of all code
2417 objects if the original filename is obsolete (which can happen if the file has
2418 been renamed, moved, or if it is accessed through different paths). Patch by

2459 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2460 instances. On a typical machine this saves 3 bytes of memory (on average) per

2472
Georg Brandlba83f822010-03-14 09:50:54 +00002473- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2474 file objects with closefd=False. The file descriptor is still kept open but
2475 the file object behaves like a closed file. The ``FileIO`` object also got a
2476 new readonly attribute ``closefd``.

2495
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002496- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002497 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002499- On windows, ``os.chdir()`` given unicode was not working if
2500 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2501 this code path is really executed because I cannot move to such directory on
2502 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002504- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2505 element is temporarily replaced with an equivalent frozenset. But the
2506 eventual KeyError would always report the empty ``frozenset()`` as the missing
2507 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002527- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2528 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2529 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2530 of using the replace error handler in PyUnicode_DecodeUTF8().
2531
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002532- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002535- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2537 gives improved memory leak detection when running under Valgrind, while taking
2538 advantage of pymalloc at other times.

3704 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3705 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3706 neither __int__ nor __long__, TypeError used to be raised (with a
3707 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3708 struct.error in other cases.

3711 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003905- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3906 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3907 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3908 ``printf`` function, whereas PyString_FromFormat has an independent
3909 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003931 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3932 mechanism. In the process, fix a bug where isinstance() and issubclass(),

3934 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3935 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004006 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4007 for catch_warnings() also led to an improvement in the raising of a
4008 DeprecationWarning related to warnings.warn_explicit().
4009
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004010- The deprecation warnings for the old camelCase threading API were removed.

4032
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004033- Issue #2975: When compiling several extension modules with Visual Studio 2008
4034 from the same python interpreter, some environment variables would grow
4035 without limit.
4036
Benjamin Peterson37346b22008-08-23 20:27:43 +00004037- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4038 exploitation of poor argument checking.
4039
Gerhard Häringef2276b2008-09-12 13:54:06 +00004040- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004074What's New in Python 2.6 beta 3?
4075================================
4076
Barry Warsaw07a4a382008-08-21 01:15:08 +00004077*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004078
4079Core and Builtins
4080-----------------
4081
Guido van Rossumf8402962008-08-20 15:01:50 +00004082- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4083 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4084 extensions do not automatically benefit from the class attribute
4085 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4086 to their tp_flags field if they care. This is a backwards
4087 compatibility feature; in 3.0, all types will use the cache by
4088 default.
4089
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004090- Keyword arguments can now follow starred arguments. (``f(a, *args,
4091 keyword=23)`` is now valid syntax.)
4092
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004093- ctypes function pointers that are COM methods have a boolean True
4094 value again.
4095
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004096- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4097 by denying s# to parse objects that have a releasebuffer procedure,
4098 and introducing s*.
4099
Georg Brandl1e13ea92008-08-11 09:07:59 +00004100- Issue #3537: Fix an assertion failure when an empty but presized dict
4101 object was stored in the freelist.
4102
Mark Dickinsonb6467572008-08-04 21:30:09 +00004103- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4104 ValueError consistently across platforms.
4105
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004106- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4107 (64bit Unix, for example), unichr() would truncate its argument and return
4108 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4109
Neal Norwitze7d8be82008-07-31 17:17:14 +00004110- Apply security patches from Apple.
4111
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004112- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4113 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4114
Antoine Pitrou92f82162008-07-25 22:22:08 +00004115- Issue #1819: function calls with several named parameters are now on
4116 average 35% faster (as measured by pybench).
4117
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004118- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4119 the python debugger steps into a class statement: the free variables (local
4120 variables defined in an outer scope) would be deleted from the outer scope.
4121
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004122- Issue #2620: Overflow checking when allocating or reallocating memory
4123 was not always being done properly in some python types and extension
4124 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4125 all been updated to perform better checks and places in the code that
4126 would previously leak memory on the error path when such an allocation
4127 failed have been fixed.
4128

4130-------
4131

4133
Benjamin Petersone977ad42008-08-20 01:42:01 +00004134- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4135 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4136
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004137- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4138 version reported by these tools does not necessarily follow the python
4139 version numbering scheme, so the module is less strict when parsing it.
4140
Nick Coghlanf70385a2008-08-18 12:42:46 +00004141- Issue #2235: Added Py3k warnings for types which will become unhashable
4142 under the stricter __hash__ inheritance rules in 3.0. Several types
4143 which did not meet the rules for hash invariants and were already
4144 unhashable in 3.0 have now been explicitly flagged as unhashable in
4145 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4146 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4147
Brett Cannon88f801d2008-08-18 00:46:22 +00004148- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4156
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004157- Issue #3575: Incremental decoder's decode function now takes bytearray
4158 by using 's*' instead of 't#'.
4159
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004160- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004161 fails unicode conversion on 2nd parameter. (windows only)
4162
Georg Brandl222e2082010-08-01 22:27:39 +00004163- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004164 in a redirect.
4165

Brett Cannon721b1452008-08-16 22:00:27 +00004167 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004168
Facundo Batistaeb90b782008-08-16 14:44:07 +00004169- Issue #2776: fixed small issue when handling an URL with double slash
4170 after a 302 response in the case of not going through a proxy.
4171
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004172- Issue #2676: in the email package, content-type parsing was hanging on
4173 pathological input because of quadratic or exponential behaviour of a
4174 regular expression.
4175
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004176- Issue #3476: binary buffered reading through the new "io" library is now
4177 thread-safe.
4178
Brett Cannonbf3157b2008-08-14 05:00:03 +00004179- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4180 since mimetools itself is deprecated. Because modules are cached, all
4181 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4182
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004183- Issue #3134: shutil referenced undefined WindowsError symbol.
4184
Robert Schuppenies14646332008-08-10 11:01:53 +00004185- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4186 menu entries were not deleted.
4187
Brett Cannon83e81842008-08-09 23:30:55 +00004188- Copied the implementation of reduce() to _functools.reduce() to have a
4189 version that did not raise a DeprecationWarning under -3.
4190
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004191- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4192 a MemoryError rather than silently stop the iteration.
4193
Guido van Rossum59ce9012008-08-09 14:55:34 +00004194- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4195 to _sre.compile() will now be rejected. This should not affect anybody
4196 since the re.compile() function never generates invalid re-bytecode.
4197
Skip Montanaroa032bf42008-08-08 22:52:51 +00004198- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4199 upon first access it can be automatically initialized from the csv file if
4200 it wasn't initialized during instantiation.
4201
Brett Cannon3aa2a492008-08-06 22:28:09 +00004202- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4203 the reload() built-in has been removed.
4204
Brett Cannon7e30b672008-08-04 21:52:25 +00004205- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004206 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004217 asking for a specific length. This problem only affected files opened
4218 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004219

4244 file name rather than a ZipInfo instance, so files are extracted with
4245 mode 0600 rather than 000 under Unix.
4246

4248 argument in python 2.5, this broke code that subclassed Popen to include its
4249 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4264 regarding lack of coverage of new-style classes have also been
4265 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004268What's New in Python 2.6 beta 2?
4269================================
4270
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004271*Release date: 17-Jul-2008*
4272
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004273Core and Builtins
4274-----------------
4275
Georg Brandl3e483f62008-07-16 22:57:41 +00004276- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4277 its methods now allow for items objects that can be converted to
4278 an integer using operator.index().
4279
Mark Dickinson64b7e502008-07-16 09:40:03 +00004280- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4281 produced a ValueError instead of giving the correct float.
4282
Eric Smitha5fa5a22008-07-16 00:11:49 +00004283- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4284 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4285
Mark Dickinson7103aa42008-07-15 19:08:33 +00004286- Issue #3008: the float type has a new instance method 'float.hex'
4287 and a new class method 'float.fromhex' to convert floating-point
4288 numbers to and from hexadecimal strings, respectively.
4289
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004290- Issue #2235: __hash__ is once again inherited by default. To allow
4291 collections.Hashable to remain meaningful in the presence of the
4292 default hash implementation (object.__hash__), it is now possible
4293 to explicit block inheritance of hash by setting __hash__=None at
4294 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4295 level.
4296
Nick Coghlanb028f502008-07-13 14:52:36 +00004297- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4298 the parent module cannot be found while performing an absolute import.
4299 This means that an incorrectly defined __package__ attribute will
4300 now only prevent relative imports in that module rather than causing
4301 all imports from that module to fail.
4302
Nick Coghlan14ff9942008-07-08 14:21:42 +00004303- Issue #2517: Allow unicode messages in Exceptions again by correctly
4304 bypassing the instance dictionary when looking up __unicode__ on
4305 new-style classes.
4306
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004307- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4308 set to a custom object whose write() method happens to install
4309 another file in sys.stdout.
4310
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004311- Issue #3088: Corrected a race condition in classes derived from
4312 threading.local: the first member set by a thread could be saved in
4313 another thread's dictionary.
4314
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004315- Issue #3004: Minor change to slice.indices(): the start and stop
4316 arguments are now treated identically, making the behaviour easier
4317 to describe and understand. For example, slice(None, -10,
4318 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4319 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4320 10, -1).
4321
Georg Brandl278fc502008-07-19 12:46:12 +00004322- Issue #3219: Calling a function with repeated keyword arguments,
4323 f(a=2, a=23), would not cause a syntax error. This was a regression
4324 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004325
Georg Brandl278fc502008-07-19 12:46:12 +00004326- Issue #2862: Make int and float freelist management consistent with
4327 other freelists. Changes their CompactFreeList apis into
4328 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004329
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004330Library
4331-------
4332
Thomas Heller57adf222008-08-14 19:10:48 +00004333- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4334 api functions without holding the GIL, which could lead to a fatal
4335 error when they failed.
4336
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004337- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4338
Jesse Noller7fb96402008-07-17 21:01:05 +00004339- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

4344
Jesse Noller13e9d582008-07-16 14:32:36 +00004345- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4346 ForkingPickler.register() to resolve conflict with ctypes.
4347
Vinay Sajip51e65192008-07-18 09:01:10 +00004348- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004349
Thomas Heller880f5292008-07-15 19:39:38 +00004350- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4351 a valid dlerror() message.
4352
Thomas Heller2bad6572008-07-15 17:19:50 +00004353- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4354 incomplete structure was created.
4355
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004356- Issue #3339: dummy_thread.acquire() should not return None.
4357
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004358- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4359
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004360- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004361
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004362- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4363 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004364 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004365 content-length. The problem had been corrected in the 2.4 branch, but never
4366 merged into trunk.
4367
Georg Brandle78fbcc2008-07-05 10:13:36 +00004368- Issue #2663: add filtering capability to shutil.copytree().
4369

4371
4372- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4373
4374- Issue #1746: Correct handling of zipfile archive comments (previously
4375 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004376 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004377
Vinay Sajip51e65192008-07-18 09:01:10 +00004378- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004379 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004380
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004381- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4382 handling is now the same as that of other special attributes like __name__).
4383
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004384- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4385 removal in Python 3.0 in favor of urllib2.urlopen().

4393
Gregory P. Smithc4691ec2008-07-07 05:09:12 +00004394- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
4395 redundant ":443" port number designation when the connection is using the

Georg Brandl3ee81df2008-05-17 18:14:43 +00004836- Issue #1631171: Re-implement the 'warnings' module in C (the
4837 original Python code has been kept as backup). This will allow for
4838 using the 'warning's machinery in such places as the parser where
4839 use of pure Python code is not possible. Both the ``showarning()``
4840 and ``formatwarning()`` gain an optional 'line' argument which is
4841 not called by default for backwards-compatibility reasons. Setting
4842 ``warnings.showwarning()`` to an implementation that lacks support
4843 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004906- Issue #2550: The approach used by client/server code for obtaining
4907 ports to listen on in network-oriented tests has been refined in an
4908 effort to facilitate running multiple instances of the entire
4909 regression test suite in parallel without issue.
4910 test_support.bind_port() has been fixed such that it will always
4911 return a unique port -- which wasn't always the case with the
4912 previous implementation, especially if socket options had been set
4913 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4914 new implementation of bind_port() will actually raise an exception
4915 if it is passed an AF_INET/SOCK_STREAM socket with either the
4916 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4917 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4918 the socket it's been passed. This currently only applies to
4919 Windows. This option prevents any other sockets from binding to the
4920 host/port we've bound to, thus removing the possibility of the
4921 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4922 when a second SOCK_STREAM socket binds and accepts to a host/port
4923 that's already been bound by another socket. The optional preferred
4924 port parameter to bind_port() has been removed. Under no
4925 circumstances should tests be hard coding ports!
4926
4927 test_support.find_unused_port() has also been introduced, which will
4928 pass a temporary socket object to bind_port() in order to obtain an
4929 unused port. The temporary socket object is then closed and
4930 deleted, and the port is returned. This method should only be used
4931 for obtaining an unused port in order to pass to an external program
4932 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4933 a parameter to a server-oriented class that doesn't give you direct
4934 access to the underlying socket used.
4935
4936 Finally, test_support.HOST has been introduced, which should be used
4937 for the host argument of any relevant socket calls (i.e. bind and
4938 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004939
4940 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004941 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004942 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4943 test_asynchat and test_socket_ssl.
4944
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945 It is now possible for multiple instances of the regression test
4946 suite to run in parallel without issue.

5102 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00005103 platform.machine() and platform.processor() will report this
5104 information as well.

5214
Fred Drakea8ee94b2008-03-01 02:45:07 +00005215- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005216 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00005225- Added the future_builtins module, which contains hex() and oct().
5226 These are the PEP 3127 version of these functions, designed to be
5227 compatible with the hex() and oct() builtins from Python 3.0. They
5228 differ slightly in their output formats from the existing, unchanged
5229 Python 2.6 builtins. The expected usage of the future_builtins
5230 module is:
5231 from future_builtins import hex, oct
5232
Eric Smith7ef40bf2008-02-20 23:34:22 +00005233- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5234 exponents for exponents with absolute value < 100. Follows C99
5235 standard. This is a change on Windows, which would use 3 digits.
5236 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5237 so that any alterations it does to the resulting string will be
5238 available in stringlib/formatter.h (for float.__format__).
5239
Eric Smith5a3c1352008-02-19 13:21:56 +00005240- Implemented PEP 3101, Advanced String Formatting. This adds a new
5241 builtin format(); a format() method for str and unicode; a
5242 __format__() method to object, str, unicode, int, long, float, and
5243 datetime; the class string.Formatter; and the C API
5244 PyObject_Format().
5245
Georg Brandl3ee81df2008-05-17 18:14:43 +00005246- Fixed several potential crashes, all caused by specially crafted
5247 __del__ methods exploiting objects in temporarily inconsistent
5248 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005249
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005250- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005251 prevent a possible crash: an Abstract Base Class would try to access
5252 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005253

Georg Brandl3ee81df2008-05-17 18:14:43 +00005257- Clear all free lists during a gc.collect() of the highest generation
5258 in order to allow pymalloc to free more arenas. Python may give back
5259 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005260
Georg Brandl3ee81df2008-05-17 18:14:43 +00005261- Issue #2045: Fix an infinite recursion triggered when printing a
5262 subclass of collections.defaultdict, if its default_factory is set
5263 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005264
Christian Heimesf75dbef2008-02-08 00:11:31 +00005265- Fixed a minor memory leak in dictobject.c. The content of the free
5266 list was not freed on interpreter shutdown.
5267
Georg Brandl21e99f42010-03-07 15:23:59 +00005268- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005270
Georg Brandl3ee81df2008-05-17 18:14:43 +00005271- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5272 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005273 to compact the internal free lists of pre-allocted ints and floats.
5274
Georg Brandl3ee81df2008-05-17 18:14:43 +00005275- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5276 calls. Python expected the return type int but the fork familie
5277 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005278
Georg Brandl3ee81df2008-05-17 18:14:43 +00005279- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005291- Patch #1473257: generator objects gain a gi_code attribute. This is
5292 the same object as the func_code attribute of the function that
5293 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005294
Georg Brandl3ee81df2008-05-17 18:14:43 +00005295- Issue #1920: "while 0" statements were completely removed by the
5296 compiler, even in the presence of an "else" clause, which is
5297 supposed to be run when the condition is false. Now the compiler
5298 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005299
Guido van Rossumeead05f2008-01-24 18:21:02 +00005300- A few crashers fixed: weakref_in_del.py (issue #1377858);
5301 loosing_dict_ref.py (issue #1303614, test67.py);
5302 borrowed_ref_[34].py (not in tracker).
5303
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005304- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005305 suppressed while an extension is loaded by calling SetErrorMode in

5307
Georg Brandl3ee81df2008-05-17 18:14:43 +00005308- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005309 several extension methods and modules do not work without unicode
5310 support.
5311
Georg Brandl26543b12008-01-21 18:36:51 +00005312- Issue #1882: when compiling code from a string, encoding cookies in the
5313 second line of code were not always recognized correctly.
5314
Georg Brandl14404b62008-01-19 19:27:05 +00005315- Issue #1679: "0x" was taken as a valid integer literal.
5316
Georg Brandl6caad7d2008-01-26 14:19:22 +00005317- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005318 added.
5319
Christian Heimesc94e2b52008-01-14 04:13:37 +00005320- sys.float_info / PyFloat_GetInfo: The floating point information
5321 object was converted from a dict to a specialized structseq object.
5322
Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- Patch #1816: Added sys.flags structseq. It exposes the status of
5324 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005325
Georg Brandl3ee81df2008-05-17 18:14:43 +00005326- Objects/structseq.c: Implemented new structseq representation. The
5327 patch makes structseqs (e.g. the return value of os.stat) more
5328 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005329
Georg Brandl3ee81df2008-05-17 18:14:43 +00005330- Patch #1700288: added a type attribute cache that caches method
5331 accesses, resulting in speedups in heavily object-oriented code.

5337
Georg Brandl3ee81df2008-05-17 18:14:43 +00005338- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5339 envvar and sys.dont_write_bytecode attribute. All these can be set
5340 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005341
Georg Brandl3ee81df2008-05-17 18:14:43 +00005342- Improve some exception messages when Windows fails to load an
5343 extension module. Now we get for example '%1 is not a valid Win32
5344 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005351- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352 and INF. float("nan"), float("inf") and float("-inf") now work on
5353 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005355- Compiler now generates simpler and faster code for dictionary
5356 literals. The oparg for BUILD_MAP now indicates an estimated
5357 dictionary size. There is a new opcode, STORE_MAP, for adding
5358 entries to the dictionary.

5388 file can now be directly executed by passing their name to the
5389 interpreter. The directory/zipfile is automatically inserted as the
5390 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005392- Issue #1265: Fix a problem with sys.settrace, if the tracing
5393 function uses a generator expression when at the same time the
5394 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005395
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005396- sets and frozensets now have an isdisjoint() method.

5401
Georg Brandl21e99f42010-03-07 15:23:59 +00005402- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005403 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5404 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005405
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Issue #1686386: Tuple's tp_repr did not take into account the
5407 possibility of having a self-referential tuple, which is possible
5408 from C code. Nor did object's tp_str consider that a type's tp_str
5409 could do something that could lead to an inifinite recursion.
5410 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5411 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005412
Georg Brandl3ee81df2008-05-17 18:14:43 +00005413- Issue #1164: It was possible to trigger deadlock when using the
5414 'print' statement to write to a file since the GIL was not released
5415 as needed. Now PyObject_Print() does the right thing along with
5416 various tp_print implementations of the built-in types and those in
5417 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005418
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00005425
Brett Cannon1e534b52007-09-07 04:18:30 +00005426- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005427 PyObject_Call() never calling back out to Python code to trigger
5428 recursion depth updates/checks. Required the creation of a static
5429 RuntimeError instance in case normalizing an exception put the
5430 recursion check value past its limit. Fixes crashers
5431 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005432

Neal Norwitz0ac60192007-05-27 04:08:54 +00005446- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005447 __*__ attributes. (Some already existed, e.g., __doc__ and
5448 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005449
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005450- Add -3 option to the interpreter to warn about features that are
5451 deprecated and will be changed/removed in Python 3.0.
5452
Georg Brandl2134e752007-05-21 20:34:16 +00005453- Patch #1686487: you can now pass any mapping after '**' in function
5454 calls.
5455
Collin Winter62903052007-05-18 23:11:24 +00005456- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457 "except E as target:". This is to provide forwards compatibility
5458 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005465- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005466 setting a plain string, ie don't expand to single letter identifiers.
5467
Raymond Hettinger13936692007-04-11 18:40:58 +00005468- Request #1191699: Slices can now be pickled.
5469
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005470- Request #1193128: str.translate() now allows a None argument for
5471 translations that only remove characters without re-mapping the
5472 remaining characters.
5473
Georg Brandl5cb76c12007-03-21 09:00:39 +00005474- Patch #1682205: a TypeError while unpacking an iterable is no longer

5478
Guido van Rossum143b5642007-03-23 04:58:42 +00005479- Bug #1683368: The object.__init__() and object.__new__() methods are
5480 now stricter in rejecting excess arguments. The only time when
5481 either allows excess arguments is when it is not overridden and the
5482 other one is. For backwards compatibility, when both are
5483 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005484 warning later). Also, type.__init__() insists on the same signature
5485 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005486
Georg Brandl3ee81df2008-05-17 18:14:43 +00005487- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5488 object to complex using its __complex__() method before falling back
5489 to the __float__() method. Therefore, the functions in the cmath
5490 module now can operate on objects that define a __complex__()
5491 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005492
Georg Brandl3ee81df2008-05-17 18:14:43 +00005493- Patch #1623563: allow __class__ assignment for classes with
5494 __slots__. The old and the new class are still required to have the
5495 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005496

5502 its type.

5508
Georg Brandl7b9c5552007-03-12 14:30:05 +00005509- Bug #1678647: write a newline after printing an exception in any
5510 case, even when converting the value to a string failed.
5511
Georg Brandl871f1bc2007-03-12 13:17:36 +00005512- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513 its argument, if it exists. If not, it will work like before. This
5514 allows customizing the output of dir() in the presence of a
5515 __getattr__().

5519
Georg Brandl3ee81df2008-05-17 18:14:43 +00005520- Patch #1675981: remove unreachable code from ``type.__new__()``

5524 parthensized forms. This means complex(repr(x)) now works instead of
5525 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005526
Georg Brandlaa2321b2007-03-07 00:40:28 +00005527- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005528 makes the filenames the warning module prints much more sensible
5529 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005530

Georg Brandl0fca97a2007-03-05 22:28:08 +00005542- Patch #1674228: when assigning a slice (old-style), check for the
5543 sq_ass_slice instead of the sq_slice slot.
5544
Georg Brandl3ee81df2008-05-17 18:14:43 +00005545- When printing an unraisable error, don't print exceptions. before
5546 the name. This duplicates the behavior whening normally printing
5547 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006080 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00006082

Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Patch #1530482: add pydoc.render_doc() which returns the

6113
Georg Brandl92a6bae2007-03-13 17:43:32 +00006114- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115 are set for invalid interpolation sequences that would lead to
6116 errors on reading back those values.

6172 TestCase and TestSuite subclasses (not instances) are no longer
6173 accepted in TestSuite.addTest(). This should cause no
6174 incompatibility since it never made sense with ordinary subclasses
6175 -- the failure just occurred later, with a more cumbersome
6176 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006565 time so that opening a database previously created with the DB_DUP
6566 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6567 opens. Specifically: dictionary assignment to a DB object will
6568 replace all values for a given key when the database allows
6569 duplicate values. DB users should use DB.put(k, v) when they want
6570 to store duplicates; not DB[k] = v.

6578 dots only if they occur on a single line, as opposed to the previous
6579 behavior of quoting dots if they are the second character of any
6580 line.

6926 of w# format code incorrectly truncated the length to an int, even
6927 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6928 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006958- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6959 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
