Ned Deily18fae3f2013-01-31 01:24:55 -0800769- Issue #13590: OS X Xcode 4 - improve support for universal extension modules

771 32-bit-only installer Pythons on systems with Xcode 4 (currently
772 OS X 10.8, 10.7, and optionally 10.6).
773 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
774 * Since Xcode 4 removes ppc support, extension module builds now
775 check for ppc compiler support and by default remove ppc and
776 ppc64 archs when they are not available.
777 * Extension module builds now revert to using system installed
778 headers and libs (/usr and /System/Library) if the SDK used
779 to build the interpreter is not installed or has moved.
780 * Try to avoid building extension modules with deprecated
781 and problematic Apple llvm-gcc compiler. If original compiler
782 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01001107- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1108 Distutils-based packages with C extension modules may fail because
1109 Apple has removed gcc-4.2, the version used to build python.org
1110 64-bit/32-bit Pythons. If the user does not explicitly override
1111 the default C compiler by setting the CC environment variable,
1112 Distutils will now attempt to compile extension modules with clang
1113 if gcc-4.2 is required but not found. Also as a convenience, if
1114 the user does explicitly set CC, substitute its value as the default
1115 compiler in the Distutils LDSHARED configuration variable for OS X.
1116 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1117 SDK, neither of which are available in Xcode 4. This change does not
1118 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001391- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1392 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1393 interpreter process. This could cause failures in non-Distutils subprocesses
1394 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001395 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001396 deployment target only in the environment of each build subprocess. It is
1397 still possible to globally override the default by setting
1398 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1399 greater or equal to the default value, the value with which the interpreter
1400 was built.

1430 the ticker doesn't have to wind down to zero from the old starting point
1431 before the new interval takes effect. And if the user increases the
1432 interval, it makes sure the new limit takes effect right away rather have an
1433 early task switch before recognizing the new interval.

2385 This prevents user-created self-referencing ordered dictionaries from
2386 becoming permanently uncollectable GC garbage. The downside is that
2387 removing __del__ means that the internal doubly-linked list has to wait for
2388 GC collection rather than freeing memory immediately when the refcnt drops
2389 to zero.

2850 of the number of bytes specified by the start byte.
2851 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003234- Issue #7301: Add environment variable $PYTHONWARNINGS.
3235
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003236- Issue #8329: Don't return the same lists from select.select when no fds are
3237 changed.
3238
Georg Brandlfee0f442010-05-22 21:26:21 +00003239- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003240 on 64-bit machines. The shift count for either left or right shift is
3241 permitted to be up to sys.maxsize.

3248
Georg Brandlfee0f442010-05-22 21:26:21 +00003249- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3250 with a non-empty format string. This is an effort to future-proof user
3251 code. If a derived class does not currently implement __format__ but later
3252 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003253 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003254 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003287- Issue #8257: The Decimal construct now accepts a float instance directly,
3288 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003289

3292
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003293- collections.Counter() now supports a subtract() method.
3294
Georg Brandlfee0f442010-05-22 21:26:21 +00003295- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00003304- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3305 InvalidOperation instead of returning False. (Comparisons involving a quiet
3306 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3307 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003308
Georg Brandlfee0f442010-05-22 21:26:21 +00003309- Issue #2531: Comparison operations between floats and Decimal instances now
3310 return a result based on the numeric values of the operands; previously they
3311 returned an arbitrary result based on the relative ordering of id(float) and
3312 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003313
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003314- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003315 argument `-` which tells it to read files to compile from stdin. Each line is
3316 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00003322- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3323 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003324 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00003326- Comparisons using one of <, <=, >, >= between a complex instance and a
3327 Fractions instance now raise TypeError instead of returning True/False. This
3328 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3329 <=> complex, and complex <=> complex comparisons.

3687 and add the additional members returned in an OSVERSIONINFOEX structure. The
3688 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003691- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3692 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3693 returning NULL. The macro now returns a statically allocated empty string
3694 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00003739- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003740 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003746- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003747 file position when calling `truncate()`. It would previously change the file
3748 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003749 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3750
Georg Brandlba83f822010-03-14 09:50:54 +00003751- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3752 class used to represent files stored inside an archive. The new
3753 implementation is significantly faster and can be wrapped in a
3754 ``io.BufferedReader`` object for more speedups. It also solves an issue
3755 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003766- Issue #7748: Since unicode values are supported for some metadata options in
3767 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3768 encoded string for them. This ensures that the upload and register commands
3769 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00003838What's New in Python 2.7 alpha 2?
3839=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00003841*Release date: 2010-01-09*

3844-----------------
3845
Georg Brandlba83f822010-03-14 09:50:54 +00003846- The ``__complex__()`` method is now looked up on the class of instances to
3847 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003848
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003849- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3850 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3851
Mark Dickinson1b34d252010-01-01 17:27:30 +00003852- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003853 DeprecationWarning when passed a float argument where an integer was expected.
3854 These functions and methods now raise TypeError instead. The majority of the
3855 effects of this change are in the extension modules, but some core functions
3856 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3857 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00003858

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003867- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3868 used to drop the time part of the result.
3869
Georg Brandlba83f822010-03-14 09:50:54 +00003870- Issue #1811: Improve accuracy and cross-platform consistency for true division
3871 of integers: the result of a/b is now correctly rounded for ints a and b (at
3872 least on IEEE 754 platforms), and in particular does not depend on the
3873 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003874
Georg Brandlba83f822010-03-14 09:50:54 +00003875- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3876 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3877 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00003878

Ronald Oussoren92919a62009-12-24 13:30:58 +00003880 executables on OSX.
3881
Georg Brandlba83f822010-03-14 09:50:54 +00003882 These executables now work properly with the arch(1) command: ``arch -ppc
3883 python`` will start a universal binary version of python in PPC mode (unlike
3884 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00003885
Georg Brandlba83f822010-03-14 09:50:54 +00003886- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
3887 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00003888

Georg Brandlba83f822010-03-14 09:50:54 +00003898- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
3899 allowing for a maximum number of tasks within the pool to be completed by the
3900 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00003906- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00003907 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3908 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00003928 Initial patch by Brian Curtin.
3929
Georg Brandlba83f822010-03-14 09:50:54 +00003930- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +00003943- Issue #7349: Make methods of file objects in the io module accept None as an
3944 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
3945 the same as passing no argument.
3946
Georg Brandlba83f822010-03-14 09:50:54 +00003947- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
3948 argument like other file objects.

Mark Dickinsona36507c2010-01-30 10:08:33 +00003968
Georg Brandlba83f822010-03-14 09:50:54 +00003969- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
3970 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3971 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3972 float arguments for integer format codes (other than 'L'): previously an
3973 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3974 TypeError. For the 'L' format code (which previously had no warning) there is
3975 now a DeprecationWarning.

4024 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004025

Georg Brandlba83f822010-03-14 09:50:54 +00004040- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4041 decimal string that's guaranteed to round back to x under correct rounding
4042 (with round-half-to-even rounding mode). Previously it gave a string based on
4043 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4044 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4045 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004046
Georg Brandlba83f822010-03-14 09:50:54 +00004047- Issue #7117: On almost all platforms: float-to-string and string-to-float
4048 conversions within Python are now correctly rounded. Places these conversions
4049 occur include: str for floats and complex numbers; the float and complex
4050 constructors; old-style and new-style numeric formatting; serialization and
4051 deserialization of floats and complex numbers using marshal, pickle and json;
4052 parsing of float and imaginary literals in Python code; Decimal-to-float
4053 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004054
Georg Brandlba83f822010-03-14 09:50:54 +00004055 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4056 providing correctly-rounded strtod and dtoa C functions. This code is
4057 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4058 the C compiler. There may be a small number of platforms on which correct
4059 operation of this code cannot be guaranteed, so the code is not used: notably,
4060 this applies to platforms where the C double format is not IEEE 754 binary64,
4061 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4062 and Python's configure script is unable to determine how to change the FPU
4063 precision. On these platforms conversions use the platform strtod and dtoa,
4064 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004065
Georg Brandlba83f822010-03-14 09:50:54 +00004066- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4067 uses the correctly-rounded string <-> float conversions described above (when
4068 available), and so produces correctly rounded results that will display nicely
4069 under the float repr. There are two related small changes: (1) round now
4070 accepts any class with an ``__index__()`` method for its second argument (but
4071 no longer accepts floats for the second argument), and (2) an excessively
4072 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

4300 internal representation of integers, for performance reasons. Base 2**30 is
4301 enabled by default on 64-bit machines. Add --enable-big-digits option to
4302 configure, which overrides the default. Add sys.long_info structseq to
4303 provide information about the internal format.

4423
Georg Brandlba83f822010-03-14 09:50:54 +00004424- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4425 file objects with closefd=False. The file descriptor is still kept open but
4426 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00004450- On windows, ``os.chdir()`` given unicode was not working if
4451 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4452 this code path is really executed because I cannot move to such directory on
4453 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004455- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4456 element is temporarily replaced with an equivalent frozenset. But the
4457 eventual KeyError would always report the empty ``frozenset()`` as the missing

4479 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005856- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5857 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5858 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5859 ``printf`` function, whereas PyString_FromFormat has an independent
5860 implementation and uses "%zd" on all platforms for size_t values.
5861 This makes a difference on win64, where ``printf`` needs "%Id" to display
5862 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005882 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5883 mechanism. In the process, fix a bug where isinstance() and issubclass(),

5885 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5886 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005957 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5958 for catch_warnings() also led to an improvement in the raising of a
5959 DeprecationWarning related to warnings.warn_explicit().
5960
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005961- The deprecation warnings for the old camelCase threading API were removed.

5983
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005984- Issue #2975: When compiling several extension modules with Visual Studio 2008
5985 from the same python interpreter, some environment variables would grow
5986 without limit.
5987
Benjamin Peterson37346b22008-08-23 20:27:43 +00005988- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5989 exploitation of poor argument checking.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006025What's New in Python 2.6 beta 3?
6026================================
6027
Barry Warsaw07a4a382008-08-21 01:15:08 +00006028*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006029
6030Core and Builtins
6031-----------------
6032
Guido van Rossumf8402962008-08-20 15:01:50 +00006033- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6034 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6035 extensions do not automatically benefit from the class attribute
6036 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6037 to their tp_flags field if they care. This is a backwards
6038 compatibility feature; in 3.0, all types will use the cache by
6039 default.
6040
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006041- Keyword arguments can now follow starred arguments. (``f(a, *args,
6042 keyword=23)`` is now valid syntax.)
6043
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006044- ctypes function pointers that are COM methods have a boolean True
6045 value again.
6046
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006047- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6048 by denying s# to parse objects that have a releasebuffer procedure,
6049 and introducing s*.
6050
Georg Brandl1e13ea92008-08-11 09:07:59 +00006051- Issue #3537: Fix an assertion failure when an empty but presized dict
6052 object was stored in the freelist.
6053
Mark Dickinsonb6467572008-08-04 21:30:09 +00006054- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6055 ValueError consistently across platforms.
6056
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006057- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6058 (64bit Unix, for example), unichr() would truncate its argument and return
6059 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6060
Neal Norwitze7d8be82008-07-31 17:17:14 +00006061- Apply security patches from Apple.
6062
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006063- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6064 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6065
Antoine Pitrou92f82162008-07-25 22:22:08 +00006066- Issue #1819: function calls with several named parameters are now on
6067 average 35% faster (as measured by pybench).
6068
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006069- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6070 the python debugger steps into a class statement: the free variables (local
6071 variables defined in an outer scope) would be deleted from the outer scope.
6072
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006073- Issue #2620: Overflow checking when allocating or reallocating memory
6074 was not always being done properly in some python types and extension
6075 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6076 all been updated to perform better checks and places in the code that
6077 would previously leak memory on the error path when such an allocation
6078 failed have been fixed.

6084
Benjamin Petersone977ad42008-08-20 01:42:01 +00006085- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6086 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6087
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006088- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6089 version reported by these tools does not necessarily follow the python
6090 version numbering scheme, so the module is less strict when parsing it.
6091
Nick Coghlanf70385a2008-08-18 12:42:46 +00006092- Issue #2235: Added Py3k warnings for types which will become unhashable
6093 under the stricter __hash__ inheritance rules in 3.0. Several types
6094 which did not meet the rules for hash invariants and were already
6095 unhashable in 3.0 have now been explicitly flagged as unhashable in
6096 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6097 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6098
Brett Cannon88f801d2008-08-18 00:46:22 +00006099- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6107
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006108- Issue #3575: Incremental decoder's decode function now takes bytearray
6109 by using 's*' instead of 't#'.
6110
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006111- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006112 fails unicode conversion on 2nd parameter. (windows only)
6113
Georg Brandl222e2082010-08-01 22:27:39 +00006114- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006115 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00006118 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006119
Facundo Batistaeb90b782008-08-16 14:44:07 +00006120- Issue #2776: fixed small issue when handling an URL with double slash
6121 after a 302 response in the case of not going through a proxy.
6122
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006123- Issue #2676: in the email package, content-type parsing was hanging on
6124 pathological input because of quadratic or exponential behaviour of a
6125 regular expression.
6126
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006127- Issue #3476: binary buffered reading through the new "io" library is now
6128 thread-safe.
6129
Brett Cannonbf3157b2008-08-14 05:00:03 +00006130- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6131 since mimetools itself is deprecated. Because modules are cached, all
6132 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6133
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006134- Issue #3134: shutil referenced undefined WindowsError symbol.
6135
Robert Schuppenies14646332008-08-10 11:01:53 +00006136- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6137 menu entries were not deleted.
6138
Brett Cannon83e81842008-08-09 23:30:55 +00006139- Copied the implementation of reduce() to _functools.reduce() to have a
6140 version that did not raise a DeprecationWarning under -3.
6141
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006142- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6143 a MemoryError rather than silently stop the iteration.
6144
Guido van Rossum59ce9012008-08-09 14:55:34 +00006145- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6146 to _sre.compile() will now be rejected. This should not affect anybody
6147 since the re.compile() function never generates invalid re-bytecode.
6148
Skip Montanaroa032bf42008-08-08 22:52:51 +00006149- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6150 upon first access it can be automatically initialized from the csv file if
6151 it wasn't initialized during instantiation.
6152
Brett Cannon3aa2a492008-08-06 22:28:09 +00006153- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6154 the reload() built-in has been removed.
6155

Antoine Pitroude781a42008-08-09 12:43:23 +00006168 asking for a specific length. This problem only affected files opened
6169 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006170

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006219What's New in Python 2.6 beta 2?
6220================================
6221
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006222*Release date: 17-Jul-2008*
6223
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006224Core and Builtins
6225-----------------
6226
Georg Brandl3e483f62008-07-16 22:57:41 +00006227- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6228 its methods now allow for items objects that can be converted to
6229 an integer using operator.index().
6230
Mark Dickinson64b7e502008-07-16 09:40:03 +00006231- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6232 produced a ValueError instead of giving the correct float.
6233
Eric Smitha5fa5a22008-07-16 00:11:49 +00006234- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6235 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6236
Mark Dickinson7103aa42008-07-15 19:08:33 +00006237- Issue #3008: the float type has a new instance method 'float.hex'
6238 and a new class method 'float.fromhex' to convert floating-point
6239 numbers to and from hexadecimal strings, respectively.
6240
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006241- Issue #2235: __hash__ is once again inherited by default. To allow
6242 collections.Hashable to remain meaningful in the presence of the
6243 default hash implementation (object.__hash__), it is now possible
6244 to explicit block inheritance of hash by setting __hash__=None at
6245 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6246 level.
6247
Nick Coghlanb028f502008-07-13 14:52:36 +00006248- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6249 the parent module cannot be found while performing an absolute import.
6250 This means that an incorrectly defined __package__ attribute will
6251 now only prevent relative imports in that module rather than causing
6252 all imports from that module to fail.
6253
Nick Coghlan14ff9942008-07-08 14:21:42 +00006254- Issue #2517: Allow unicode messages in Exceptions again by correctly
6255 bypassing the instance dictionary when looking up __unicode__ on
6256 new-style classes.
6257
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006258- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6259 set to a custom object whose write() method happens to install
6260 another file in sys.stdout.
6261
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006262- Issue #3088: Corrected a race condition in classes derived from
6263 threading.local: the first member set by a thread could be saved in
6264 another thread's dictionary.
6265
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006266- Issue #3004: Minor change to slice.indices(): the start and stop
6267 arguments are now treated identically, making the behaviour easier
6268 to describe and understand. For example, slice(None, -10,
6269 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6270 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6271 10, -1).
6272
Georg Brandl278fc502008-07-19 12:46:12 +00006273- Issue #3219: Calling a function with repeated keyword arguments,
6274 f(a=2, a=23), would not cause a syntax error. This was a regression
6275 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006276
Georg Brandl278fc502008-07-19 12:46:12 +00006277- Issue #2862: Make int and float freelist management consistent with
6278 other freelists. Changes their CompactFreeList apis into
6279 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006280
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006281Library
6282-------
6283
Thomas Heller57adf222008-08-14 19:10:48 +00006284- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6285 api functions without holding the GIL, which could lead to a fatal
6286 error when they failed.
6287
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006288- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
6289

6295
Jesse Noller13e9d582008-07-16 14:32:36 +00006296- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6297 ForkingPickler.register() to resolve conflict with ctypes.
6298
Vinay Sajip51e65192008-07-18 09:01:10 +00006299- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006300
Thomas Heller880f5292008-07-15 19:39:38 +00006301- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6302 a valid dlerror() message.
6303
Thomas Heller2bad6572008-07-15 17:19:50 +00006304- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6305 incomplete structure was created.
6306
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006307- Issue #3339: dummy_thread.acquire() should not return None.
6308
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006309- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6310
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006311- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006312
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006313- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6314 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006315 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006316 content-length. The problem had been corrected in the 2.4 branch, but never
6317 merged into trunk.
6318
Georg Brandle78fbcc2008-07-05 10:13:36 +00006319- Issue #2663: add filtering capability to shutil.copytree().

6322
6323- Issue #1526: Allow more than 64k files to be added to Zip64 file.
6324
6325- Issue #1746: Correct handling of zipfile archive comments (previously
6326 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006327 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006328
Vinay Sajip51e65192008-07-18 09:01:10 +00006329- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006330 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006331
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006332- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6333 handling is now the same as that of other special attributes like __name__).
6334
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006335- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6336 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006787- Issue #1631171: Re-implement the 'warnings' module in C (the
6788 original Python code has been kept as backup). This will allow for
6789 using the 'warning's machinery in such places as the parser where
6790 use of pure Python code is not possible. Both the ``showarning()``
6791 and ``formatwarning()`` gain an optional 'line' argument which is
6792 not called by default for backwards-compatibility reasons. Setting
6793 ``warnings.showwarning()`` to an implementation that lacks support
6794 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006857- Issue #2550: The approach used by client/server code for obtaining
6858 ports to listen on in network-oriented tests has been refined in an
6859 effort to facilitate running multiple instances of the entire
6860 regression test suite in parallel without issue.
6861 test_support.bind_port() has been fixed such that it will always
6862 return a unique port -- which wasn't always the case with the
6863 previous implementation, especially if socket options had been set
6864 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6865 new implementation of bind_port() will actually raise an exception
6866 if it is passed an AF_INET/SOCK_STREAM socket with either the
6867 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6868 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6869 the socket it's been passed. This currently only applies to
6870 Windows. This option prevents any other sockets from binding to the
6871 host/port we've bound to, thus removing the possibility of the
6872 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6873 when a second SOCK_STREAM socket binds and accepts to a host/port
6874 that's already been bound by another socket. The optional preferred
6875 port parameter to bind_port() has been removed. Under no
6876 circumstances should tests be hard coding ports!
6877
6878 test_support.find_unused_port() has also been introduced, which will
6879 pass a temporary socket object to bind_port() in order to obtain an
6880 unused port. The temporary socket object is then closed and
6881 deleted, and the port is returned. This method should only be used
6882 for obtaining an unused port in order to pass to an external program
6883 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6884 a parameter to a server-oriented class that doesn't give you direct
6885 access to the underlying socket used.
6886
6887 Finally, test_support.HOST has been introduced, which should be used
6888 for the host argument of any relevant socket calls (i.e. bind and
6889 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006890
6891 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006892 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006893 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6894 test_asynchat and test_socket_ssl.
6895
Georg Brandl3ee81df2008-05-17 18:14:43 +00006896 It is now possible for multiple instances of the regression test
6897 suite to run in parallel without issue.

7053 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00007054 platform.machine() and platform.processor() will report this
7055 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00007176- Added the future_builtins module, which contains hex() and oct().
7177 These are the PEP 3127 version of these functions, designed to be
7178 compatible with the hex() and oct() builtins from Python 3.0. They
7179 differ slightly in their output formats from the existing, unchanged
7180 Python 2.6 builtins. The expected usage of the future_builtins
7181 module is:
7182 from future_builtins import hex, oct
7183
Eric Smith7ef40bf2008-02-20 23:34:22 +00007184- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7185 exponents for exponents with absolute value < 100. Follows C99
7186 standard. This is a change on Windows, which would use 3 digits.
7187 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7188 so that any alterations it does to the resulting string will be
7189 available in stringlib/formatter.h (for float.__format__).
7190
Eric Smith5a3c1352008-02-19 13:21:56 +00007191- Implemented PEP 3101, Advanced String Formatting. This adds a new
7192 builtin format(); a format() method for str and unicode; a
7193 __format__() method to object, str, unicode, int, long, float, and
7194 datetime; the class string.Formatter; and the C API
7195 PyObject_Format().
7196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Fixed several potential crashes, all caused by specially crafted
7198 __del__ methods exploiting objects in temporarily inconsistent
7199 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007200
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007201- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007202 prevent a possible crash: an Abstract Base Class would try to access
7203 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007208- Clear all free lists during a gc.collect() of the highest generation
7209 in order to allow pymalloc to free more arenas. Python may give back
7210 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007211
Georg Brandl3ee81df2008-05-17 18:14:43 +00007212- Issue #2045: Fix an infinite recursion triggered when printing a
7213 subclass of collections.defaultdict, if its default_factory is set
7214 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007215
Christian Heimesf75dbef2008-02-08 00:11:31 +00007216- Fixed a minor memory leak in dictobject.c. The content of the free
7217 list was not freed on interpreter shutdown.
7218
Georg Brandl21e99f42010-03-07 15:23:59 +00007219- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00007221
Georg Brandl3ee81df2008-05-17 18:14:43 +00007222- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7223 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007224 to compact the internal free lists of pre-allocted ints and floats.
7225
Georg Brandl3ee81df2008-05-17 18:14:43 +00007226- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7227 calls. Python expected the return type int but the fork familie
7228 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007229
Georg Brandl3ee81df2008-05-17 18:14:43 +00007230- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00007242- Patch #1473257: generator objects gain a gi_code attribute. This is
7243 the same object as the func_code attribute of the function that
7244 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007245
Georg Brandl3ee81df2008-05-17 18:14:43 +00007246- Issue #1920: "while 0" statements were completely removed by the
7247 compiler, even in the presence of an "else" clause, which is
7248 supposed to be run when the condition is false. Now the compiler
7249 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007250
Guido van Rossumeead05f2008-01-24 18:21:02 +00007251- A few crashers fixed: weakref_in_del.py (issue #1377858);
7252 loosing_dict_ref.py (issue #1303614, test67.py);
7253 borrowed_ref_[34].py (not in tracker).
7254

7258
Georg Brandl3ee81df2008-05-17 18:14:43 +00007259- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007260 several extension methods and modules do not work without unicode
7261 support.
7262
Georg Brandl26543b12008-01-21 18:36:51 +00007263- Issue #1882: when compiling code from a string, encoding cookies in the

7265
Georg Brandl14404b62008-01-19 19:27:05 +00007266- Issue #1679: "0x" was taken as a valid integer literal.
7267
Georg Brandl6caad7d2008-01-26 14:19:22 +00007268- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007269 added.
7270
Christian Heimesc94e2b52008-01-14 04:13:37 +00007271- sys.float_info / PyFloat_GetInfo: The floating point information
7272 object was converted from a dict to a specialized structseq object.
7273
Georg Brandl3ee81df2008-05-17 18:14:43 +00007274- Patch #1816: Added sys.flags structseq. It exposes the status of
7275 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007276
Georg Brandl3ee81df2008-05-17 18:14:43 +00007277- Objects/structseq.c: Implemented new structseq representation. The

7288
Georg Brandl3ee81df2008-05-17 18:14:43 +00007289- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7290 envvar and sys.dont_write_bytecode attribute. All these can be set
7291 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007292
Georg Brandl3ee81df2008-05-17 18:14:43 +00007293- Improve some exception messages when Windows fails to load an
7294 extension module. Now we get for example '%1 is not a valid Win32
7295 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007302- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007303 and INF. float("nan"), float("inf") and float("-inf") now work on
7304 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007306- Compiler now generates simpler and faster code for dictionary
7307 literals. The oparg for BUILD_MAP now indicates an estimated
7308 dictionary size. There is a new opcode, STORE_MAP, for adding
7309 entries to the dictionary.

7339 file can now be directly executed by passing their name to the
7340 interpreter. The directory/zipfile is automatically inserted as the
7341 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007343- Issue #1265: Fix a problem with sys.settrace, if the tracing
7344 function uses a generator expression when at the same time the
7345 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007346
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007347- sets and frozensets now have an isdisjoint() method.

7352
Georg Brandl21e99f42010-03-07 15:23:59 +00007353- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007354 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7355 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007356
Georg Brandl3ee81df2008-05-17 18:14:43 +00007357- Issue #1686386: Tuple's tp_repr did not take into account the
7358 possibility of having a self-referential tuple, which is possible
7359 from C code. Nor did object's tp_str consider that a type's tp_str
7360 could do something that could lead to an inifinite recursion.
7361 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7362 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007363
Georg Brandl3ee81df2008-05-17 18:14:43 +00007364- Issue #1164: It was possible to trigger deadlock when using the
7365 'print' statement to write to a file since the GIL was not released
7366 as needed. Now PyObject_Print() does the right thing along with
7367 various tp_print implementations of the built-in types and those in
7368 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007369
Georg Brandl3ee81df2008-05-17 18:14:43 +00007370- Issue #1147: Exceptions were directly allowing string exceptions in
7371 their throw() method even though string exceptions no longer
7372 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007374- Issue #1096: Prevent a segfault from getting the repr of a very
7375 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007376
Brett Cannon1e534b52007-09-07 04:18:30 +00007377- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007378 PyObject_Call() never calling back out to Python code to trigger
7379 recursion depth updates/checks. Required the creation of a static
7380 RuntimeError instance in case normalizing an exception put the
7381 recursion check value past its limit. Fixes crashers
7382 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007383

Neal Norwitz0ac60192007-05-27 04:08:54 +00007397- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007398 __*__ attributes. (Some already existed, e.g., __doc__ and
7399 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007400
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007401- Add -3 option to the interpreter to warn about features that are
7402 deprecated and will be changed/removed in Python 3.0.
7403
Georg Brandl2134e752007-05-21 20:34:16 +00007404- Patch #1686487: you can now pass any mapping after '**' in function
7405 calls.
7406
Collin Winter62903052007-05-18 23:11:24 +00007407- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408 "except E as target:". This is to provide forwards compatibility
7409 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007416- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007417 setting a plain string, ie don't expand to single letter identifiers.
7418
Raymond Hettinger13936692007-04-11 18:40:58 +00007419- Request #1191699: Slices can now be pickled.
7420
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007421- Request #1193128: str.translate() now allows a None argument for
7422 translations that only remove characters without re-mapping the
7423 remaining characters.
7424
Georg Brandl5cb76c12007-03-21 09:00:39 +00007425- Patch #1682205: a TypeError while unpacking an iterable is no longer

7429
Guido van Rossum143b5642007-03-23 04:58:42 +00007430- Bug #1683368: The object.__init__() and object.__new__() methods are
7431 now stricter in rejecting excess arguments. The only time when
7432 either allows excess arguments is when it is not overridden and the
7433 other one is. For backwards compatibility, when both are
7434 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007435 warning later). Also, type.__init__() insists on the same signature
7436 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007437
Georg Brandl3ee81df2008-05-17 18:14:43 +00007438- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7439 object to complex using its __complex__() method before falling back
7440 to the __float__() method. Therefore, the functions in the cmath
7441 module now can operate on objects that define a __complex__()
7442 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007443
Georg Brandl3ee81df2008-05-17 18:14:43 +00007444- Patch #1623563: allow __class__ assignment for classes with
7445 __slots__. The old and the new class are still required to have the
7446 same slot names.

7453 its type.

7459
Georg Brandl7b9c5552007-03-12 14:30:05 +00007460- Bug #1678647: write a newline after printing an exception in any
7461 case, even when converting the value to a string failed.
7462
Georg Brandl871f1bc2007-03-12 13:17:36 +00007463- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464 its argument, if it exists. If not, it will work like before. This
7465 allows customizing the output of dir() in the presence of a
7466 __getattr__().

7470
Georg Brandl3ee81df2008-05-17 18:14:43 +00007471- Patch #1675981: remove unreachable code from ``type.__new__()``

7475 parthensized forms. This means complex(repr(x)) now works instead of
7476 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007477
Georg Brandlaa2321b2007-03-07 00:40:28 +00007478- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007479 makes the filenames the warning module prints much more sensible
7480 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007481

Georg Brandl0fca97a2007-03-05 22:28:08 +00007493- Patch #1674228: when assigning a slice (old-style), check for the
7494 sq_ass_slice instead of the sq_slice slot.
7495
Georg Brandl3ee81df2008-05-17 18:14:43 +00007496- When printing an unraisable error, don't print exceptions. before
7497 the name. This duplicates the behavior whening normally printing
7498 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008031 AttributeError instead of an IOError when the server's response
8032 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008033

Georg Brandl3ee81df2008-05-17 18:14:43 +00008049- Patch #1530482: add pydoc.render_doc() which returns the

8064
Georg Brandl92a6bae2007-03-13 17:43:32 +00008065- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008066 are set for invalid interpolation sequences that would lead to
8067 errors on reading back those values.

8123 TestCase and TestSuite subclasses (not instances) are no longer
8124 accepted in TestSuite.addTest(). This should cause no
8125 incompatibility since it never made sense with ordinary subclasses
8126 -- the failure just occurred later, with a more cumbersome
8127 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008516 time so that opening a database previously created with the DB_DUP
8517 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8518 opens. Specifically: dictionary assignment to a DB object will
8519 replace all values for a given key when the database allows
8520 duplicate values. DB users should use DB.put(k, v) when they want
8521 to store duplicates; not DB[k] = v.

8530 behavior of quoting dots if they are the second character of any
8531 line.

8877 of w# format code incorrectly truncated the length to an int, even
8878 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8879 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008909- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8910 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
