689 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100690 compiler optimizing the check away. Also fix similar overflow checks
691 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +0100767- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
768 Distutils-based packages with C extension modules may fail because
769 Apple has removed gcc-4.2, the version used to build python.org
770 64-bit/32-bit Pythons. If the user does not explicitly override
771 the default C compiler by setting the CC environment variable,
772 Distutils will now attempt to compile extension modules with clang
773 if gcc-4.2 is required but not found. Also as a convenience, if
774 the user does explicitly set CC, substitute its value as the default
775 compiler in the Distutils LDSHARED configuration variable for OS X.
776 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
777 SDK, neither of which are available in Xcode 4. This change does not
778 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001051- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1052 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1053 interpreter process. This could cause failures in non-Distutils subprocesses
1054 and was unreliable since tests or user programs could modify the interpreter
1055 environment after Distutils set it. Instead, have Distutils set the the
1056 deployment target only in the environment of each build subprocess. It is
1057 still possible to globally override the default by setting
1058 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1059 greater or equal to the default value, the value with which the interpreter
1060 was built.

1089 updating the check interval, so if the user decreases the check interval,
1090 the ticker doesn't have to wind down to zero from the old starting point
1091 before the new interval takes effect. And if the user increases the
1092 interval, it makes sure the new limit takes effect right away rather have an
1093 early task switch before recognizing the new interval.

2043
Raymond Hettinger20397532010-09-12 02:11:45 +00002044- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2045 This prevents user-created self-referencing ordered dictionaries from
2046 becoming permanently uncollectable GC garbage. The downside is that
2047 removing __del__ means that the internal doubly-linked list has to wait for
2048 GC collection rather than freeing memory immediately when the refcnt drops
2049 to zero.

2102
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002103- Issue #9626: the view methods for collections.OrderedDict() were returning

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002508- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2509 start byte and the continuation byte(s) are now considered invalid, instead
2510 of the number of bytes specified by the start byte.
2511 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2512 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2513 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2523 objects. (1) The comparison could incorrectly return True in some cases
2524 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2525 (2) The comparison raised an OverflowError for large integers, leading

2667 non-float non-integer argument is now converted to an integer (if possible)
2668 using its __int__ method. Previously, only small arguments were treated this
2669 way; larger arguments (those whose __int__ was outside the range of a C long)

2721 operation raises multiple signals and more than one of those signals is
2722 trapped, the specification determines the order in which the signals should be

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002869 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2870 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

2891Core and Builtins
2892-----------------
2893
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002894- Issue #7301: Add environment variable $PYTHONWARNINGS.
2895
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002896- Issue #8329: Don't return the same lists from select.select when no fds are
2897 changed.
2898
Georg Brandlfee0f442010-05-22 21:26:21 +00002899- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002900 on 64-bit machines. The shift count for either left or right shift is
2901 permitted to be up to sys.maxsize.
2902
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002903- Ensure that tokenization of identifiers is not affected by locale.
2904
Georg Brandlfee0f442010-05-22 21:26:21 +00002905- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002907- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2908
Georg Brandlfee0f442010-05-22 21:26:21 +00002909- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2910 with a non-empty format string. This is an effort to future-proof user
2911 code. If a derived class does not currently implement __format__ but later
2912 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002913 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002914 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002915
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002916- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002929- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002930 (SIGINT). If an error occurs while importing the site module, the error is

2946
Georg Brandlfee0f442010-05-22 21:26:21 +00002947- Issue #8257: The Decimal construct now accepts a float instance directly,
2948 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002949
2950 >>> Decimal(1.1)
2951 Decimal('1.100000000000000088817841970012523233890533447265625')
2952
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002953- collections.Counter() now supports a subtract() method.
2954
Georg Brandlfee0f442010-05-22 21:26:21 +00002955- The functools module now has a total_ordering() class decorator to simplify
2956 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002958- The functools module also adds cmp_to_key() as a tool to transition old-style
2959 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002960
Georg Brandlfee0f442010-05-22 21:26:21 +00002961- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2962 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002963
Georg Brandlfee0f442010-05-22 21:26:21 +00002964- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2965 InvalidOperation instead of returning False. (Comparisons involving a quiet
2966 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2967 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002968
Georg Brandlfee0f442010-05-22 21:26:21 +00002969- Issue #2531: Comparison operations between floats and Decimal instances now
2970 return a result based on the numeric values of the operands; previously they
2971 returned an arbitrary result based on the relative ordering of id(float) and
2972 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002973
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002974- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002975 argument `-` which tells it to read files to compile from stdin. Each line is
2976 read on demand and the named file is compiled immediately. (Original patch by
2977 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002982- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2983 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002984 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00002986- Comparisons using one of <, <=, >, >= between a complex instance and a
2987 Fractions instance now raise TypeError instead of returning True/False. This
2988 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2989 <=> complex, and complex <=> complex comparisons.

3094 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3095 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003096 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3097 inconsistent: __int__ was used for some integer codes but not for others, and
3098 the set of integer codes for which it was used differed between native packing
3099 and standard packing.)

3313 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3314 Xicluna who helped with the patch.

3352 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3353 returning NULL. The macro now returns a statically allocated empty string

Georg Brandlba83f822010-03-14 09:50:54 +00003407 file position when calling `truncate()`. It would previously change the file
3408 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003409 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3410

3412 class used to represent files stored inside an archive. The new
3413 implementation is significantly faster and can be wrapped in a
3414 ``io.BufferedReader`` object for more speedups. It also solves an issue
3415 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3416 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003426- Issue #7748: Since unicode values are supported for some metadata options in
3427 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3428 encoded string for them. This ensures that the upload and register commands
3429 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003542 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003700- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3701 decimal string that's guaranteed to round back to x under correct rounding
3702 (with round-half-to-even rounding mode). Previously it gave a string based on
3703 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3704 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3705 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003706
Georg Brandlba83f822010-03-14 09:50:54 +00003707- Issue #7117: On almost all platforms: float-to-string and string-to-float
3708 conversions within Python are now correctly rounded. Places these conversions
3709 occur include: str for floats and complex numbers; the float and complex
3710 constructors; old-style and new-style numeric formatting; serialization and
3711 deserialization of floats and complex numbers using marshal, pickle and json;
3712 parsing of float and imaginary literals in Python code; Decimal-to-float
3713 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003714
Georg Brandlba83f822010-03-14 09:50:54 +00003715 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3716 providing correctly-rounded strtod and dtoa C functions. This code is
3717 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3718 the C compiler. There may be a small number of platforms on which correct
3719 operation of this code cannot be guaranteed, so the code is not used: notably,
3720 this applies to platforms where the C double format is not IEEE 754 binary64,
3721 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3722 and Python's configure script is unable to determine how to change the FPU
3723 precision. On these platforms conversions use the platform strtod and dtoa,
3724 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003726- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3727 uses the correctly-rounded string <-> float conversions described above (when
3728 available), and so produces correctly rounded results that will display nicely
3729 under the float repr. There are two related small changes: (1) round now
3730 accepts any class with an ``__index__()`` method for its second argument (but
3731 no longer accepts floats for the second argument), and (2) an excessively
3732 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3733 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003876 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3877 (2) parsing of strings representing infinities and nans was locale aware; and
3878 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003880- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3881 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3882 but with at least one decimal point and with a default precision
3883 of 12. Previously, the behavior the same but with a default precision of 6.
3884 This more closely matches ``str()``, and reduces surprises when adding
3885 alignment flags to the empty presentation type. This also affects the new
3886 complex.__format__ in the same way.
3887
3888- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4019 collecting the oldest generation) so that allocating lots of objects without
4020 destroying them does not show quadratic performance. Based on a proposal by

4025
Georg Brandlba83f822010-03-14 09:50:54 +00004026- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4027 existing .py counterpart, override the co_filename attributes of all code
4028 objects if the original filename is obsolete (which can happen if the file has
4029 been renamed, moved, or if it is accessed through different paths). Patch by
4030 Ziga Seilnacht and Jean-Paul Calderone.

4048
Georg Brandl6425a2f2008-12-28 11:54:53 +00004049- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004050 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Skip Montanarof205c132008-12-23 03:30:15 +00004052- Added test case to ensure attempts to read from a file opened for writing
4053 fail.

Georg Brandlba83f822010-03-14 09:50:54 +00004069- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4070 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4071 instances. On a typical machine this saves 3 bytes of memory (on average) per
4072 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004074- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4075 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4076 instead of throwing a MemoryError.
4077
Georg Brandlba83f822010-03-14 09:50:54 +00004078- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4079 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00004081- Issue #4367: Python would segfault during compiling when the unicodedata

4083
Georg Brandlba83f822010-03-14 09:50:54 +00004084- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4085 file objects with closefd=False. The file descriptor is still kept open but
4086 the file object behaves like a closed file. The ``FileIO`` object also got a
4087 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004089- Issue #4348: Some bytearray methods returned that didn't cause any change to
4090 the bytearray, returned the same bytearray instead of a copy.
4091
Georg Brandlba83f822010-03-14 09:50:54 +00004092- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00004104- Issue #4209: Enabling unicode_literals and the print_function in the same
4105 __future__ import didn't work.
4106
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004107- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004108 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00004110- On windows, ``os.chdir()`` given unicode was not working if
4111 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4112 this code path is really executed because I cannot move to such directory on
4113 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004114
Georg Brandlba83f822010-03-14 09:50:54 +00004115- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4116 element is temporarily replaced with an equivalent frozenset. But the
4117 eventual KeyError would always report the empty ``frozenset()`` as the missing
4118 key. Now it correctly refers to the initial element.

4136 returned them on 64bit platforms.
4137
Walter Dörwalded960ac2009-05-03 22:36:33 +00004138- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4139 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4140 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4141 of using the replace error handler in PyUnicode_DecodeUTF8().
4142
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004143- Issue #3739: The unicode-internal encoder now reports the number of characters
4144 consumed like any other encoder (instead of the number of bytes).
4145
Georg Brandlba83f822010-03-14 09:50:54 +00004146- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4147 allocator will be automatically disabled when running under Valgrind. This
4148 gives improved memory leak detection when running under Valgrind, while taking
4149 advantage of pymalloc at other times.

5380 __all__ attribute, rather than using a hardcoded and incomplete list.
5381
R. David Murray14dcd432009-10-14 13:58:07 +00005382- Issue #7058: Added save/restore for things like sys.argv and cwd to
5383 runtest_inner in regrtest, with warnings if the called test modifies them,
5384 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005391- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5392 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005393 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5394 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00005396- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5397 regression tests in parallel, shortening the total runtime.
5398
Georg Brandlba83f822010-03-14 09:50:54 +00005399- Issue #5354: New test support function import_fresh_module() makes it easy to
5400 import both normal and optimised versions of modules. test_heapq and
5401 test_warnings have been adjusted to use it, tests for other modules with both
5402 C and Python implementations in the stdlib can be adjusted to use it over
5403 time.

5410
Georg Brandlba83f822010-03-14 09:50:54 +00005411- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5412 should cause a test to be skipped are now done using import_module from test
5413 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005514- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5515
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005516- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5517 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5518 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5519 ``printf`` function, whereas PyString_FromFormat has an independent
5520 implementation and uses "%zd" on all platforms for size_t values.
5521 This makes a difference on win64, where ``printf`` needs "%Id" to display
5522 64bit values.
5523
Benjamin Peterson97179b02008-09-09 20:55:01 +00005524- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5528 object; previously an int would be returned for small values. the __long__
5529 method is allowed to return either an int or a long, but the behaviour of
5530 float objects should not change to respect backward compatibility.
5531
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005532- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005538 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005539 was correctly parsed but parsing of subsequent arguments failed.
5540
Vinay Sajip35e3b032008-09-01 14:33:59 +00005541- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005542 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5543 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5544 when given a tuple of classes as second argument, were looking up
5545 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5546 type object.
5547
Neal Norwitz18aa3882008-08-24 05:04:52 +00005548- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005685What's New in Python 2.6 beta 3?
5686================================
5687
Barry Warsaw07a4a382008-08-21 01:15:08 +00005688*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005689
5690Core and Builtins
5691-----------------
5692
Guido van Rossumf8402962008-08-20 15:01:50 +00005693- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5694 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5695 extensions do not automatically benefit from the class attribute
5696 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5697 to their tp_flags field if they care. This is a backwards
5698 compatibility feature; in 3.0, all types will use the cache by
5699 default.
5700
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005701- Keyword arguments can now follow starred arguments. (``f(a, *args,
5702 keyword=23)`` is now valid syntax.)
5703
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005704- ctypes function pointers that are COM methods have a boolean True
5705 value again.
5706
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005707- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5708 by denying s# to parse objects that have a releasebuffer procedure,
5709 and introducing s*.
5710
Georg Brandl1e13ea92008-08-11 09:07:59 +00005711- Issue #3537: Fix an assertion failure when an empty but presized dict
5712 object was stored in the freelist.
5713
Mark Dickinsonb6467572008-08-04 21:30:09 +00005714- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5715 ValueError consistently across platforms.
5716
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005717- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5718 (64bit Unix, for example), unichr() would truncate its argument and return
5719 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5720
Neal Norwitze7d8be82008-07-31 17:17:14 +00005721- Apply security patches from Apple.
5722
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005723- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5724 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5725
Antoine Pitrou92f82162008-07-25 22:22:08 +00005726- Issue #1819: function calls with several named parameters are now on
5727 average 35% faster (as measured by pybench).
5728
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005729- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5730 the python debugger steps into a class statement: the free variables (local
5731 variables defined in an outer scope) would be deleted from the outer scope.
5732
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005733- Issue #2620: Overflow checking when allocating or reallocating memory
5734 was not always being done properly in some python types and extension
5735 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5736 all been updated to perform better checks and places in the code that
5737 would previously leak memory on the error path when such an allocation
5738 failed have been fixed.

5742
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005743- Issue #3612: Added some missing basic types in ctypes.wintypes.
5744
Benjamin Petersone977ad42008-08-20 01:42:01 +00005745- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5746 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5747
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005748- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5749 version reported by these tools does not necessarily follow the python
5750 version numbering scheme, so the module is less strict when parsing it.
5751
Nick Coghlanf70385a2008-08-18 12:42:46 +00005752- Issue #2235: Added Py3k warnings for types which will become unhashable
5753 under the stricter __hash__ inheritance rules in 3.0. Several types
5754 which did not meet the rules for hash invariants and were already
5755 unhashable in 3.0 have now been explicitly flagged as unhashable in
5756 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5757 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5758
Brett Cannon88f801d2008-08-18 00:46:22 +00005759- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5760 imported into the module but exposed as part of the module's API.
5761
Brett Cannon7b96f072008-08-18 00:41:11 +00005762- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5763
Brett Cannon46225e72008-08-18 00:36:52 +00005764- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5765
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005766- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5767
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005768- Issue #3575: Incremental decoder's decode function now takes bytearray
5769 by using 's*' instead of 't#'.
5770
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005771- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005772 fails unicode conversion on 2nd parameter. (windows only)
5773
Georg Brandl222e2082010-08-01 22:27:39 +00005774- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005775 in a redirect.
5776
Brett Cannonabe423e2008-08-16 21:47:07 +00005777- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005778 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005779
Facundo Batistaeb90b782008-08-16 14:44:07 +00005780- Issue #2776: fixed small issue when handling an URL with double slash
5781 after a 302 response in the case of not going through a proxy.
5782
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005783- Issue #2676: in the email package, content-type parsing was hanging on
5784 pathological input because of quadratic or exponential behaviour of a
5785 regular expression.
5786
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005787- Issue #3476: binary buffered reading through the new "io" library is now
5788 thread-safe.
5789
Brett Cannonbf3157b2008-08-14 05:00:03 +00005790- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5791 since mimetools itself is deprecated. Because modules are cached, all
5792 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5793
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005794- Issue #3134: shutil referenced undefined WindowsError symbol.
5795
Robert Schuppenies14646332008-08-10 11:01:53 +00005796- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5797 menu entries were not deleted.
5798
Brett Cannon83e81842008-08-09 23:30:55 +00005799- Copied the implementation of reduce() to _functools.reduce() to have a
5800 version that did not raise a DeprecationWarning under -3.
5801
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005802- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5803 a MemoryError rather than silently stop the iteration.
5804
Guido van Rossum59ce9012008-08-09 14:55:34 +00005805- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5806 to _sre.compile() will now be rejected. This should not affect anybody
5807 since the re.compile() function never generates invalid re-bytecode.
5808
Skip Montanaroa032bf42008-08-08 22:52:51 +00005809- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5810 upon first access it can be automatically initialized from the csv file if
5811 it wasn't initialized during instantiation.
5812
Brett Cannon3aa2a492008-08-06 22:28:09 +00005813- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5814 the reload() built-in has been removed.
5815
Brett Cannon7e30b672008-08-04 21:52:25 +00005816- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005817 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5825 raised an AttributeError.
5826
Benjamin Peterson01a24322008-07-28 23:35:27 +00005827- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005828 asking for a specific length. This problem only affected files opened
5829 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005830
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005831- Issue #3449: Update decimal module to use most recent specification
5832 (v. 1.68) and tests (v. 2.58) from IBM.
5833
Georg Brandl222e2082010-08-01 22:27:39 +00005834- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5842
5843- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5844 invalid arguments.
5845
5846- Issue #3302: Fix several crashes when calling locale's gettext functions
5847 with None arguments.
5848
5849- Issue #3389: Allow resolving dotted names for handlers in logging
5850 configuration files.
5851
5852- Deprecate the sunaudio module for removal in Python 3.0.
5853
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005854- Issue #3394: zipfile.writestr sets external attributes when passed a
5855 file name rather than a ZipInfo instance, so files are extracted with
5856 mode 0600 rather than 000 under Unix.
5857
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005858- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5859 argument in python 2.5, this broke code that subclassed Popen to include its
5860 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005870- Issue #2235: the C API function PyObject_HashNotImplemented and its
5871 interaction with the tp_hash slot (added in 2.6b2) are now documented
5872
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005873- Issue #643841: The language reference now provides more detailed
5874 coverage of the lookup process for special methods. The disclaimers
5875 regarding lack of coverage of new-style classes have also been
5876 removed, since the coverage is now fairly reasonable.

5885-----------------
5886
Georg Brandl3e483f62008-07-16 22:57:41 +00005887- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5888 its methods now allow for items objects that can be converted to
5889 an integer using operator.index().
5890
Mark Dickinson64b7e502008-07-16 09:40:03 +00005891- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5892 produced a ValueError instead of giving the correct float.
5893
Eric Smitha5fa5a22008-07-16 00:11:49 +00005894- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5895 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5896
Mark Dickinson7103aa42008-07-15 19:08:33 +00005897- Issue #3008: the float type has a new instance method 'float.hex'
5898 and a new class method 'float.fromhex' to convert floating-point
5899 numbers to and from hexadecimal strings, respectively.
5900
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005901- Issue #2235: __hash__ is once again inherited by default. To allow
5902 collections.Hashable to remain meaningful in the presence of the
5903 default hash implementation (object.__hash__), it is now possible
5904 to explicit block inheritance of hash by setting __hash__=None at
5905 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5906 level.
5907
Nick Coghlanb028f502008-07-13 14:52:36 +00005908- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5909 the parent module cannot be found while performing an absolute import.
5910 This means that an incorrectly defined __package__ attribute will
5911 now only prevent relative imports in that module rather than causing
5912 all imports from that module to fail.
5913
Nick Coghlan14ff9942008-07-08 14:21:42 +00005914- Issue #2517: Allow unicode messages in Exceptions again by correctly
5915 bypassing the instance dictionary when looking up __unicode__ on
5916 new-style classes.

5924 another thread's dictionary.
5925
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005926- Issue #3004: Minor change to slice.indices(): the start and stop
5927 arguments are now treated identically, making the behaviour easier
5928 to describe and understand. For example, slice(None, -10,
5929 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5930 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5931 10, -1).
5932
Georg Brandl278fc502008-07-19 12:46:12 +00005933- Issue #3219: Calling a function with repeated keyword arguments,

5935 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006385 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006386
6387 This is controlled by the configure argument ``--with-universal-archs``:
6388
6389 - ``--with-universal-archs=all``: install 4-way universal
6390
6391 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6392
6393 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6394
6395 This option should be used in combination with ``--enable-universalsdk=``.
6396
6397 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

6434 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006435
Christian Heimese74c8f22008-04-19 02:23:57 +00006436- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006447- Issue #1631171: Re-implement the 'warnings' module in C (the
6448 original Python code has been kept as backup). This will allow for
6449 using the 'warning's machinery in such places as the parser where
6450 use of pure Python code is not possible. Both the ``showarning()``
6451 and ``formatwarning()`` gain an optional 'line' argument which is
6452 not called by default for backwards-compatibility reasons. Setting
6453 ``warnings.showwarning()`` to an implementation that lacks support
6454 for the ``line`` argument will raise a DeprecationWarning.

6478
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006479- The getpass module has been improved on Unix. It now uses /dev/tty
6480 by default and uses stderr instead of stdout. A GetPassWarning is
6481 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006496- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006497 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006509- Issue #2385: distutils.core.run_script() makes __file__ available,
6510 so the controlled environment will more closely mirror the typical
6511 script environment. This supports setup.py scripts that refer to
6512 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006517- Issue #2550: The approach used by client/server code for obtaining
6518 ports to listen on in network-oriented tests has been refined in an
6519 effort to facilitate running multiple instances of the entire
6520 regression test suite in parallel without issue.
6521 test_support.bind_port() has been fixed such that it will always
6522 return a unique port -- which wasn't always the case with the
6523 previous implementation, especially if socket options had been set
6524 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6525 new implementation of bind_port() will actually raise an exception
6526 if it is passed an AF_INET/SOCK_STREAM socket with either the
6527 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6528 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6529 the socket it's been passed. This currently only applies to
6530 Windows. This option prevents any other sockets from binding to the
6531 host/port we've bound to, thus removing the possibility of the
6532 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6533 when a second SOCK_STREAM socket binds and accepts to a host/port
6534 that's already been bound by another socket. The optional preferred
6535 port parameter to bind_port() has been removed. Under no
6536 circumstances should tests be hard coding ports!
6537
6538 test_support.find_unused_port() has also been introduced, which will
6539 pass a temporary socket object to bind_port() in order to obtain an
6540 unused port. The temporary socket object is then closed and
6541 deleted, and the port is returned. This method should only be used
6542 for obtaining an unused port in order to pass to an external program
6543 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6544 a parameter to a server-oriented class that doesn't give you direct
6545 access to the underlying socket used.
6546
6547 Finally, test_support.HOST has been introduced, which should be used
6548 for the host argument of any relevant socket calls (i.e. bind and
6549 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006550
6551 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006552 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006553 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6554 test_asynchat and test_socket_ssl.
6555
Georg Brandl3ee81df2008-05-17 18:14:43 +00006556 It is now possible for multiple instances of the regression test
6557 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006836- Added the future_builtins module, which contains hex() and oct().
6837 These are the PEP 3127 version of these functions, designed to be
6838 compatible with the hex() and oct() builtins from Python 3.0. They
6839 differ slightly in their output formats from the existing, unchanged
6840 Python 2.6 builtins. The expected usage of the future_builtins
6841 module is:
6842 from future_builtins import hex, oct
6843
Eric Smith7ef40bf2008-02-20 23:34:22 +00006844- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6845 exponents for exponents with absolute value < 100. Follows C99
6846 standard. This is a change on Windows, which would use 3 digits.
6847 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6848 so that any alterations it does to the resulting string will be
6849 available in stringlib/formatter.h (for float.__format__).
6850
Eric Smith5a3c1352008-02-19 13:21:56 +00006851- Implemented PEP 3101, Advanced String Formatting. This adds a new
6852 builtin format(); a format() method for str and unicode; a
6853 __format__() method to object, str, unicode, int, long, float, and
6854 datetime; the class string.Formatter; and the C API
6855 PyObject_Format().
6856
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857- Fixed several potential crashes, all caused by specially crafted
6858 __del__ methods exploiting objects in temporarily inconsistent
6859 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006860
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006861- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006862 prevent a possible crash: an Abstract Base Class would try to access
6863 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006864
Georg Brandl3ee81df2008-05-17 18:14:43 +00006865- Fixed repr() and str() of complex numbers with infinity or nan as
6866 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006868- Clear all free lists during a gc.collect() of the highest generation
6869 in order to allow pymalloc to free more arenas. Python may give back
6870 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006871
Georg Brandl3ee81df2008-05-17 18:14:43 +00006872- Issue #2045: Fix an infinite recursion triggered when printing a
6873 subclass of collections.defaultdict, if its default_factory is set
6874 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006875
Christian Heimesf75dbef2008-02-08 00:11:31 +00006876- Fixed a minor memory leak in dictobject.c. The content of the free
6877 list was not freed on interpreter shutdown.
6878
Georg Brandl21e99f42010-03-07 15:23:59 +00006879- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006880 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006881
Georg Brandl3ee81df2008-05-17 18:14:43 +00006882- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6883 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006884 to compact the internal free lists of pre-allocted ints and floats.
6885
Georg Brandl3ee81df2008-05-17 18:14:43 +00006886- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6887 calls. Python expected the return type int but the fork familie
6888 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006889
Georg Brandl3ee81df2008-05-17 18:14:43 +00006890- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006902- Patch #1473257: generator objects gain a gi_code attribute. This is
6903 the same object as the func_code attribute of the function that
6904 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006905
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906- Issue #1920: "while 0" statements were completely removed by the
6907 compiler, even in the presence of an "else" clause, which is
6908 supposed to be run when the condition is false. Now the compiler
6909 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006910
Guido van Rossumeead05f2008-01-24 18:21:02 +00006911- A few crashers fixed: weakref_in_del.py (issue #1377858);
6912 loosing_dict_ref.py (issue #1303614, test67.py);
6913 borrowed_ref_[34].py (not in tracker).
6914
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006915- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006916 suppressed while an extension is loaded by calling SetErrorMode in
6917 dynload_win.c. The error is still reported properly.
6918
Georg Brandl3ee81df2008-05-17 18:14:43 +00006919- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006920 several extension methods and modules do not work without unicode
6921 support.
6922
Georg Brandl26543b12008-01-21 18:36:51 +00006923- Issue #1882: when compiling code from a string, encoding cookies in the
6924 second line of code were not always recognized correctly.
6925
Georg Brandl14404b62008-01-19 19:27:05 +00006926- Issue #1679: "0x" was taken as a valid integer literal.
6927
Georg Brandl6caad7d2008-01-26 14:19:22 +00006928- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006929 added.
6930
Christian Heimesc94e2b52008-01-14 04:13:37 +00006931- sys.float_info / PyFloat_GetInfo: The floating point information
6932 object was converted from a dict to a specialized structseq object.
6933
Georg Brandl3ee81df2008-05-17 18:14:43 +00006934- Patch #1816: Added sys.flags structseq. It exposes the status of
6935 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006936
Georg Brandl3ee81df2008-05-17 18:14:43 +00006937- Objects/structseq.c: Implemented new structseq representation. The
6938 patch makes structseqs (e.g. the return value of os.stat) more
6939 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006940
Georg Brandl3ee81df2008-05-17 18:14:43 +00006941- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006963 and INF. float("nan"), float("inf") and float("-inf") now work on
6964 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006965
Georg Brandl3ee81df2008-05-17 18:14:43 +00006966- Compiler now generates simpler and faster code for dictionary
6967 literals. The oparg for BUILD_MAP now indicates an estimated
6968 dictionary size. There is a new opcode, STORE_MAP, for adding
6969 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00007013- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007014 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7015 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007016
Georg Brandl3ee81df2008-05-17 18:14:43 +00007017- Issue #1686386: Tuple's tp_repr did not take into account the
7018 possibility of having a self-referential tuple, which is possible
7019 from C code. Nor did object's tp_str consider that a type's tp_str
7020 could do something that could lead to an inifinite recursion.
7021 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7022 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007023
Georg Brandl3ee81df2008-05-17 18:14:43 +00007024- Issue #1164: It was possible to trigger deadlock when using the
7025 'print' statement to write to a file since the GIL was not released
7026 as needed. Now PyObject_Print() does the right thing along with
7027 various tp_print implementations of the built-in types and those in
7028 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007029
Georg Brandl3ee81df2008-05-17 18:14:43 +00007030- Issue #1147: Exceptions were directly allowing string exceptions in
7031 their throw() method even though string exceptions no longer
7032 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007033
Georg Brandl3ee81df2008-05-17 18:14:43 +00007034- Issue #1096: Prevent a segfault from getting the repr of a very
7035 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007036
Brett Cannon1e534b52007-09-07 04:18:30 +00007037- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007038 PyObject_Call() never calling back out to Python code to trigger
7039 recursion depth updates/checks. Required the creation of a static
7040 RuntimeError instance in case normalizing an exception put the
7041 recursion check value past its limit. Fixes crashers
7042 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007043

Neal Norwitz0ac60192007-05-27 04:08:54 +00007057- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007058 __*__ attributes. (Some already existed, e.g., __doc__ and
7059 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007060
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007061- Add -3 option to the interpreter to warn about features that are
7062 deprecated and will be changed/removed in Python 3.0.
7063
Georg Brandl2134e752007-05-21 20:34:16 +00007064- Patch #1686487: you can now pass any mapping after '**' in function
7065 calls.
7066
Collin Winter62903052007-05-18 23:11:24 +00007067- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007068 "except E as target:". This is to provide forwards compatibility
7069 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007076- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007077 setting a plain string, ie don't expand to single letter identifiers.
7078
Raymond Hettinger13936692007-04-11 18:40:58 +00007079- Request #1191699: Slices can now be pickled.
7080
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007081- Request #1193128: str.translate() now allows a None argument for
7082 translations that only remove characters without re-mapping the
7083 remaining characters.
7084
Georg Brandl5cb76c12007-03-21 09:00:39 +00007085- Patch #1682205: a TypeError while unpacking an iterable is no longer

7089
Guido van Rossum143b5642007-03-23 04:58:42 +00007090- Bug #1683368: The object.__init__() and object.__new__() methods are
7091 now stricter in rejecting excess arguments. The only time when
7092 either allows excess arguments is when it is not overridden and the
7093 other one is. For backwards compatibility, when both are
7094 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007095 warning later). Also, type.__init__() insists on the same signature
7096 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007097
Georg Brandl3ee81df2008-05-17 18:14:43 +00007098- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7099 object to complex using its __complex__() method before falling back
7100 to the __float__() method. Therefore, the functions in the cmath
7101 module now can operate on objects that define a __complex__()
7102 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007103
Georg Brandl3ee81df2008-05-17 18:14:43 +00007104- Patch #1623563: allow __class__ assignment for classes with

7113 its type.

7119
Georg Brandl7b9c5552007-03-12 14:30:05 +00007120- Bug #1678647: write a newline after printing an exception in any
7121 case, even when converting the value to a string failed.
7122
Georg Brandl871f1bc2007-03-12 13:17:36 +00007123- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007124 its argument, if it exists. If not, it will work like before. This
7125 allows customizing the output of dir() in the presence of a
7126 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007134- Patch #1491866: change the complex() constructor to allow
7135 parthensized forms. This means complex(repr(x)) now works instead of
7136 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007137
Georg Brandlaa2321b2007-03-07 00:40:28 +00007138- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007139 makes the filenames the warning module prints much more sensible
7140 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007141

Georg Brandl0fca97a2007-03-05 22:28:08 +00007153- Patch #1674228: when assigning a slice (old-style), check for the
7154 sq_ass_slice instead of the sq_slice slot.
7155
Georg Brandl3ee81df2008-05-17 18:14:43 +00007156- When printing an unraisable error, don't print exceptions. before
7157 the name. This duplicates the behavior whening normally printing
7158 exceptions.

7786 -- the failure just occurred later, with a more cumbersome
7787 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008068- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8069 with RFC 3207 and forgets any knowledge obtained from the server not
8070 obtained from the TLS negotiation itself. Patch contributed by Bill
8071 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008072
Georg Brandl3ee81df2008-05-17 18:14:43 +00008073- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008074 that the SMTP.starttls() caller no longer needs to call ehlo()
8075 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008076 does not claim to support starttls. Adds the
8077 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8158 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8159 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008176 time so that opening a database previously created with the DB_DUP
8177 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8178 opens. Specifically: dictionary assignment to a DB object will
8179 replace all values for a given key when the database allows
8180 duplicate values. DB users should use DB.put(k, v) when they want
8181 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008182

8188 characters with ASCII value less than 32. Also, it correctly quotes
8189 dots only if they occur on a single line, as opposed to the previous
8190 behavior of quoting dots if they are the second character of any
8191 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008192

8514-----
8515
Georg Brandl3ee81df2008-05-17 18:14:43 +00008516- Unified naming convention for free lists and their limits. All free
8517 lists in Object/ are named ``free_list``, the counter ``numfree``
8518 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8519 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008520
Georg Brandl3ee81df2008-05-17 18:14:43 +00008521- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8522 to ``PyTuple_SetItem``, it can be used to populate a brand new
8523 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008524
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008525- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

8528 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8529 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008530
8531- Patch #1720595: add T_BOOL to the range of structmember types.
8532
8533- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8534 ``PyFloat_GetInfo()`` to the float API.
8535
Georg Brandl3ee81df2008-05-17 18:14:43 +00008536- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8537 of w# format code incorrectly truncated the length to an int, even
8538 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8539 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008540
Georg Brandl3ee81df2008-05-17 18:14:43 +00008541- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8542 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008543
Georg Brandl3ee81df2008-05-17 18:14:43 +00008544- PEP 3123: Provide forward compatibility with Python 3.0, while
8545 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8546 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008547
Georg Brandl3ee81df2008-05-17 18:14:43 +00008548- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8549 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008550
8551- Patch #1733960: Allow T_LONGLONG to accept ints.

8558
8559- Fix some leftovers from the conversion from int to Py_ssize_t
8560 (relevant to strings and sequences of more than 2**31 items).
8561
8562- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8563 outside of pystate.c and should not be necessary.
8564
Georg Brandl3ee81df2008-05-17 18:14:43 +00008565- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8566 absolute imports. In earlier versions they might have used relative
8567 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008568
Georg Brandl3ee81df2008-05-17 18:14:43 +00008569- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8570 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008571
Georg Brandl3ee81df2008-05-17 18:14:43 +00008572- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8573 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008579- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8580 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8581 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8582 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008583

Georg Brandl3ee81df2008-05-17 18:14:43 +00008597- Removed the macfs module. It had been deprecated since Python 2.5.
8598 This lead to the deprecation of macostools.touched() as it relied
8599 solely on macfs and was a no-op under OS X.
