42
R. David Murray27ef9372010-04-12 14:26:06 +000043- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

60
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000061- Issue #7301: Add environment variable $PYTHONWARNINGS.
62
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000063- Issue #8329: Don't return the same lists from select.select when no fds are
64 changed.

75
Eric Smithd44b2fc2010-04-02 12:30:56 +000076- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
77 is called with a non-empty format string. This is an effort to
78 future-proof user code. If a derived class does not currently
79 implement __format__ but later adds its own __format__, it would
80 most likely break user code that had supplied a format string. This
81 will be changed to a DeprecationWaring in Python 3.3 and it will be
82 an error in Python 3.4.
83
Antoine Pitroua57df2c2010-03-31 21:32:15 +000084- Issue #8268: Old-style classes (not just instances) now support weak

110 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
111 and `ssl.OPENSSL_VERSION_NUMBER`.
112
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000113- Issue #8310: Allow dis to examine new style classes.
114
Mark Dickinson8a950712010-04-03 15:47:46 +0000115- Issue #8257: The Decimal construct now accepts a float instance
116 directly, converting that float to a Decimal of equal value:

Raymond Hettinger34c35b22010-04-03 10:22:00 +0000121- collections.Counter() now supports a subtract() method.
122
Raymond Hettingera551f312010-04-04 18:34:45 +0000123- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000124 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000125
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000126- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000127 old-style comparison functions to new-style key-functions.

Mark Dickinsone096e822010-04-02 10:17:07 +0000132- Issue #7279: Comparisons involving a Decimal signaling NaN now
133 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000134 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
135 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000136
Mark Dickinson99d80962010-04-02 08:53:22 +0000137- Issue #2531: Comparison operations between floats and Decimal
138 instances now return a result based on the numeric values of the
139 operands; previously they returned an arbitrary result based on
140 the relative ordering of id(float) and id(Decimal).
141
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000142- Issue #8233: When run as a script, py_compile.py optionally takes a single
143 argument `-` which tells it to read files to compile from stdin. Each line
144 is read on demand and the named file is compiled immediately. (Original
145 patch by Piotr Ożarowski).
146
147- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
148 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000149
Florent Xicluna58b65662010-03-30 16:29:03 +0000150- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
151 form feed (0x0C) are now considered linebreaks, as specified in Unicode
152 Standard Annex #14. See issue #7643.

154
Mark Dickinson9588d992010-03-27 11:14:37 +0000155- Comparisons using one of <, <=, >, >= between a complex instance and
156 a Fractions instance now raise TypeError instead of returning
157 True/False. This makes Fraction <=> complex comparisons consistent with
158 int <=> complex, float <=> complex, and complex <=> complex comparisons.
159
Michael Foorde6410c52010-03-29 20:04:23 +0000160- Addition of ``WeakSet`` to the ``weakref`` module.

171 now silenced.
172
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000173- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

180 method to LoggerAdapter.
181
Vinay Sajip31e928e2010-03-22 13:02:28 +0000182- Issue #8201: logging: Handle situation of non-ASCII and Unicode
183 logger names existing at the same time, causing a Unicode error
184 when configuration code attempted to sort the existing loggers.
185
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000186- Issue #8200: logging: Handle errors when multiprocessing is not

Georg Brandlba83f822010-03-14 09:50:54 +0000214 for ``TimedRotatingFileHandler`` by using the modification time of an
215 existing log file to compute the next rollover time. If the log file does
216 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000217

Georg Brandlba83f822010-03-14 09:50:54 +0000226- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
227 a base64 transfer-encoded payload *after* decoding it; it no longer does.
228 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000255- Issue #8300: When passing a non-integer argument to struct.pack with any
256 integer format code, struct.pack first attempts to convert the non-integer
257 using its __index__ method. If that method is non-existent or raises
258 TypeError it goes on to try the __int__ method, as described below.
259
Georg Brandlba83f822010-03-14 09:50:54 +0000260- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
261 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
262 argument's __int__ method to convert to an integer before packing. It also
263 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
264 was inconsistent: __int__ was used for some integer codes but not for others,
265 and the set of integer codes for which it was used differed between native
266 packing and standard packing.)

565 position to the given argument, which goes against the tradition of

662Core and Builtins
663-----------------
664
Georg Brandlba83f822010-03-14 09:50:54 +0000665- The ``__complex__()`` method is now looked up on the class of instances to
666 make it consistent with other special methods.

670
Mark Dickinson1b34d252010-01-01 17:27:30 +0000671- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000672 DeprecationWarning when passed a float argument where an integer was expected.
673 These functions and methods now raise TypeError instead. The majority of the
674 effects of this change are in the extension modules, but some core functions
675 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
676 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000689- Issue #1811: Improve accuracy and cross-platform consistency for true division
690 of integers: the result of a/b is now correctly rounded for ints a and b (at
691 least on IEEE 754 platforms), and in particular does not depend on the
692 internal representation of a long.

700
Georg Brandlba83f822010-03-14 09:50:54 +0000701 These executables now work properly with the arch(1) command: ``arch -ppc
702 python`` will start a universal binary version of python in PPC mode (unlike

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000858
Georg Brandlba83f822010-03-14 09:50:54 +0000859- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
860 decimal string that's guaranteed to round back to x under correct rounding
861 (with round-half-to-even rounding mode). Previously it gave a string based on
862 rounding x to 17 decimal digits. repr(x) for a complex number behaves
863 similarly. On platforms where the correctly-rounded strtod and dtoa code is
864 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000865
Georg Brandlba83f822010-03-14 09:50:54 +0000866- Issue #7117: On almost all platforms: float-to-string and string-to-float
867 conversions within Python are now correctly rounded. Places these conversions
868 occur include: str for floats and complex numbers; the float and complex
869 constructors; old-style and new-style numeric formatting; serialization and
870 deserialization of floats and complex numbers using marshal, pickle and json;
871 parsing of float and imaginary literals in Python code; Decimal-to-float
872 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000873
Georg Brandlba83f822010-03-14 09:50:54 +0000874 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
875 providing correctly-rounded strtod and dtoa C functions. This code is
876 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
877 the C compiler. There may be a small number of platforms on which correct
878 operation of this code cannot be guaranteed, so the code is not used: notably,
879 this applies to platforms where the C double format is not IEEE 754 binary64,
880 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
881 and Python's configure script is unable to determine how to change the FPU
882 precision. On these platforms conversions use the platform strtod and dtoa,
883 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000885- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
886 uses the correctly-rounded string <-> float conversions described above (when
887 available), and so produces correctly rounded results that will display nicely
888 under the float repr. There are two related small changes: (1) round now
889 accepts any class with an ``__index__()`` method for its second argument (but
890 no longer accepts floats for the second argument), and (2) an excessively
891 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
892 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001034
Georg Brandlba83f822010-03-14 09:50:54 +00001035 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1036 (2) parsing of strings representing infinities and nans was locale aware; and
1037 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001039- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1040 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1041 but with at least one decimal point and with a default precision
1042 of 12. Previously, the behavior the same but with a default precision of 6.
1043 This more closely matches ``str()``, and reduces surprises when adding
1044 alignment flags to the empty presentation type. This also affects the new
1045 complex.__format__ in the same way.
1046
1047- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002472 - If x is not an int, long or float, then packing x will always result in
2473 struct.error. Previously an x with an __int__ method could be packed by
2474 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2475 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2476 neither __int__ nor __long__, TypeError used to be raised (with a
2477 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2478 struct.error in other cases.

2481 argument with an __int__ method can be packed, but use of this feature
2482 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00002531 leak-chasing test runs give sensible results. The previous method of reaping
2532 threads could return successfully while some Thread objects were still

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002654 AttributeError instead of RuntimeError, depending in which C API call
2655 exactly the recursion limit is exceeded. Consequently, both exception types

2672
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002673- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2674
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002675- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2676 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2677 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2678 ``printf`` function, whereas PyString_FromFormat has an independent
2679 implementation and uses "%zd" on all platforms for size_t values.
2680 This makes a difference on win64, where ``printf`` needs "%Id" to display
2681 64bit values.
2682
Benjamin Peterson97179b02008-09-09 20:55:01 +00002683- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2684 error.
2685
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002686- Issue #3777: long() applied to a float object now always return a long
2687 object; previously an int would be returned for small values. the __long__
2688 method is allowed to return either an int or a long, but the behaviour of
2689 float objects should not change to respect backward compatibility.
2690
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002691- Issue #3751: str.rpartition would perform a left-partition when called with
2692 a unicode argument.
2693
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002694- Issue #3683: Fix compilation when --without-threads is given.
2695
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002696- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002697 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002698 was correctly parsed but parsing of subsequent arguments failed.
2699
Vinay Sajip35e3b032008-09-01 14:33:59 +00002700- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002701 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2702 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2703 when given a tuple of classes as second argument, were looking up
2704 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2705 type object.
2706
Neal Norwitz18aa3882008-08-24 05:04:52 +00002707- Fix crashes on memory allocation failure found with failmalloc.
2708
2709- Fix memory leaks found with valgrind and update suppressions file.
2710
2711- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2712
2713- Fix problem using wrong name in decimal module reported by pychecker.
2714
Christian Heimes7d4c3172008-08-22 19:47:25 +00002715- Silenced another compiler warning about a used but not defined
2716 function 'stringlib_contains_obj'.
2717

Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002721- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2722 library targets in the Makefile.
2723
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002724- Issue #1204: The configure script now tests for additional libraries
2725 that may be required when linking against readline. This fixes issues
2726 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2748
Nick Coghland2e09382008-09-11 12:11:06 +00002749- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002750 return a list or None rather than a custom object.
2751
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002752- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2776 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2777 for catch_warnings() also led to an improvement in the raising of a
2778 DeprecationWarning related to warnings.warn_explicit().
2779
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002780- The deprecation warnings for the old camelCase threading API were removed.

2850-----------------
2851
Guido van Rossumf8402962008-08-20 15:01:50 +00002852- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2853 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2854 extensions do not automatically benefit from the class attribute
2855 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2856 to their tp_flags field if they care. This is a backwards
2857 compatibility feature; in 3.0, all types will use the cache by
2858 default.
2859
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002860- Keyword arguments can now follow starred arguments. (``f(a, *args,
2861 keyword=23)`` is now valid syntax.)
2862
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002863- ctypes function pointers that are COM methods have a boolean True
2864 value again.
2865
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002866- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2867 by denying s# to parse objects that have a releasebuffer procedure,
2868 and introducing s*.
2869
Georg Brandl1e13ea92008-08-11 09:07:59 +00002870- Issue #3537: Fix an assertion failure when an empty but presized dict
2871 object was stored in the freelist.
2872
Mark Dickinsonb6467572008-08-04 21:30:09 +00002873- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2874 ValueError consistently across platforms.
2875
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002876- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2877 (64bit Unix, for example), unichr() would truncate its argument and return
2878 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2879
Neal Norwitze7d8be82008-07-31 17:17:14 +00002880- Apply security patches from Apple.
2881
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002882- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2883 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2884
Antoine Pitrou92f82162008-07-25 22:22:08 +00002885- Issue #1819: function calls with several named parameters are now on
2886 average 35% faster (as measured by pybench).
2887
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002888- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2889 the python debugger steps into a class statement: the free variables (local
2890 variables defined in an outer scope) would be deleted from the outer scope.
2891
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002892- Issue #2620: Overflow checking when allocating or reallocating memory
2893 was not always being done properly in some python types and extension
2894 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2895 all been updated to perform better checks and places in the code that
2896 would previously leak memory on the error path when such an allocation
2897 failed have been fixed.

2901
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002902- Issue #3612: Added some missing basic types in ctypes.wintypes.
2903
Benjamin Petersone977ad42008-08-20 01:42:01 +00002904- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2905 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2906
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002907- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2908 version reported by these tools does not necessarily follow the python
2909 version numbering scheme, so the module is less strict when parsing it.
2910
Nick Coghlanf70385a2008-08-18 12:42:46 +00002911- Issue #2235: Added Py3k warnings for types which will become unhashable
2912 under the stricter __hash__ inheritance rules in 3.0. Several types
2913 which did not meet the rules for hash invariants and were already
2914 unhashable in 3.0 have now been explicitly flagged as unhashable in
2915 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2916 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2917
Brett Cannon88f801d2008-08-18 00:46:22 +00002918- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2919 imported into the module but exposed as part of the module's API.
2920
Brett Cannon7b96f072008-08-18 00:41:11 +00002921- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2922

3031
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003032- Issue #643841: The language reference now provides more detailed

3044-----------------
3045
Georg Brandl3e483f62008-07-16 22:57:41 +00003046- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3047 its methods now allow for items objects that can be converted to
3048 an integer using operator.index().
3049
Mark Dickinson64b7e502008-07-16 09:40:03 +00003050- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3051 produced a ValueError instead of giving the correct float.
3052
Eric Smitha5fa5a22008-07-16 00:11:49 +00003053- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3054 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3055
Mark Dickinson7103aa42008-07-15 19:08:33 +00003056- Issue #3008: the float type has a new instance method 'float.hex'
3057 and a new class method 'float.fromhex' to convert floating-point
3058 numbers to and from hexadecimal strings, respectively.
3059
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003060- Issue #2235: __hash__ is once again inherited by default. To allow
3061 collections.Hashable to remain meaningful in the presence of the
3062 default hash implementation (object.__hash__), it is now possible
3063 to explicit block inheritance of hash by setting __hash__=None at
3064 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3065 level.
3066
Nick Coghlanb028f502008-07-13 14:52:36 +00003067- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3068 the parent module cannot be found while performing an absolute import.
3069 This means that an incorrectly defined __package__ attribute will
3070 now only prevent relative imports in that module rather than causing
3071 all imports from that module to fail.
3072
Nick Coghlan14ff9942008-07-08 14:21:42 +00003073- Issue #2517: Allow unicode messages in Exceptions again by correctly

3083 another thread's dictionary.
3084
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003085- Issue #3004: Minor change to slice.indices(): the start and stop
3086 arguments are now treated identically, making the behaviour easier
3087 to describe and understand. For example, slice(None, -10,
3088 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3089 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3090 10, -1).
3091
Georg Brandl278fc502008-07-19 12:46:12 +00003092- Issue #3219: Calling a function with repeated keyword arguments,
3093 f(a=2, a=23), would not cause a syntax error. This was a regression
3094 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003096- Issue #2862: Make int and float freelist management consistent with
3097 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003132- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3133 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003134 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003135 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003151- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003542- On MacOS X it is now possible to install the framework in 64-bit
3543 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003544 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003545
3546 This is controlled by the configure argument ``--with-universal-archs``:
3547
3548 - ``--with-universal-archs=all``: install 4-way universal
3549
3550 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3551
3552 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3553
3554 This option should be used in combination with ``--enable-universalsdk=``.
3555
3556 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003606- Issue #1631171: Re-implement the 'warnings' module in C (the
3607 original Python code has been kept as backup). This will allow for
3608 using the 'warning's machinery in such places as the parser where
3609 use of pure Python code is not possible. Both the ``showarning()``
3610 and ``formatwarning()`` gain an optional 'line' argument which is
3611 not called by default for backwards-compatibility reasons. Setting
3612 ``warnings.showwarning()`` to an implementation that lacks support
3613 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Issue #2550: The approach used by client/server code for obtaining
3677 ports to listen on in network-oriented tests has been refined in an
3678 effort to facilitate running multiple instances of the entire
3679 regression test suite in parallel without issue.
3680 test_support.bind_port() has been fixed such that it will always
3681 return a unique port -- which wasn't always the case with the
3682 previous implementation, especially if socket options had been set
3683 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3684 new implementation of bind_port() will actually raise an exception
3685 if it is passed an AF_INET/SOCK_STREAM socket with either the
3686 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3687 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3688 the socket it's been passed. This currently only applies to
3689 Windows. This option prevents any other sockets from binding to the
3690 host/port we've bound to, thus removing the possibility of the
3691 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3692 when a second SOCK_STREAM socket binds and accepts to a host/port
3693 that's already been bound by another socket. The optional preferred
3694 port parameter to bind_port() has been removed. Under no
3695 circumstances should tests be hard coding ports!
3696
3697 test_support.find_unused_port() has also been introduced, which will
3698 pass a temporary socket object to bind_port() in order to obtain an
3699 unused port. The temporary socket object is then closed and
3700 deleted, and the port is returned. This method should only be used
3701 for obtaining an unused port in order to pass to an external program
3702 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3703 a parameter to a server-oriented class that doesn't give you direct
3704 access to the underlying socket used.
3705
3706 Finally, test_support.HOST has been introduced, which should be used
3707 for the host argument of any relevant socket calls (i.e. bind and
3708 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003709
3710 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003711 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003712 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3713 test_asynchat and test_socket_ssl.
3714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715 It is now possible for multiple instances of the regression test
3716 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003770- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003771 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3772 Plane. This affected raw unicode literals and the
3773 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3774 this case, like normal unicode literals and the 'unicode-escape'
3775 codec.

3983-----------------
3984
Fred Drakea8ee94b2008-03-01 02:45:07 +00003985- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003986 644. The mode is now inherited from the py file.

3989
3990- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003991
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003992- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003993 issue 215555 for a discussion.
3994
Eric Smitha73fbe72008-02-23 03:09:44 +00003995- Added the future_builtins module, which contains hex() and oct().
3996 These are the PEP 3127 version of these functions, designed to be
3997 compatible with the hex() and oct() builtins from Python 3.0. They
3998 differ slightly in their output formats from the existing, unchanged
3999 Python 2.6 builtins. The expected usage of the future_builtins
4000 module is:
4001 from future_builtins import hex, oct
4002
Eric Smith7ef40bf2008-02-20 23:34:22 +00004003- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4004 exponents for exponents with absolute value < 100. Follows C99
4005 standard. This is a change on Windows, which would use 3 digits.
4006 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4007 so that any alterations it does to the resulting string will be
4008 available in stringlib/formatter.h (for float.__format__).
4009
Eric Smith5a3c1352008-02-19 13:21:56 +00004010- Implemented PEP 3101, Advanced String Formatting. This adds a new
4011 builtin format(); a format() method for str and unicode; a
4012 __format__() method to object, str, unicode, int, long, float, and
4013 datetime; the class string.Formatter; and the C API
4014 PyObject_Format().
4015
Georg Brandl3ee81df2008-05-17 18:14:43 +00004016- Fixed several potential crashes, all caused by specially crafted
4017 __del__ methods exploiting objects in temporarily inconsistent
4018 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004019
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004020- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021 prevent a possible crash: an Abstract Base Class would try to access
4022 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004023
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Clear all free lists during a gc.collect() of the highest generation
4028 in order to allow pymalloc to free more arenas. Python may give back
4029 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Issue #2045: Fix an infinite recursion triggered when printing a
4032 subclass of collections.defaultdict, if its default_factory is set
4033 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004034
Christian Heimesf75dbef2008-02-08 00:11:31 +00004035- Fixed a minor memory leak in dictobject.c. The content of the free
4036 list was not freed on interpreter shutdown.
4037
Georg Brandl21e99f42010-03-07 15:23:59 +00004038- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004040
Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4042 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``

4044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4046 calls. Python expected the return type int but the fork familie
4047 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004048
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Patch #1473257: generator objects gain a gi_code attribute. This is
4062 the same object as the func_code attribute of the function that
4063 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Issue #1920: "while 0" statements were completely removed by the
4066 compiler, even in the presence of an "else" clause, which is
4067 supposed to be run when the condition is false. Now the compiler
4068 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004069
Guido van Rossumeead05f2008-01-24 18:21:02 +00004070- A few crashers fixed: weakref_in_del.py (issue #1377858);
4071 loosing_dict_ref.py (issue #1303614, test67.py);
4072 borrowed_ref_[34].py (not in tracker).
4073
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004074- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004075 suppressed while an extension is loaded by calling SetErrorMode in
4076 dynload_win.c. The error is still reported properly.
4077
Georg Brandl3ee81df2008-05-17 18:14:43 +00004078- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004079 several extension methods and modules do not work without unicode
4080 support.
4081
Georg Brandl26543b12008-01-21 18:36:51 +00004082- Issue #1882: when compiling code from a string, encoding cookies in the

4086
Georg Brandl6caad7d2008-01-26 14:19:22 +00004087- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004088 added.
4089
Christian Heimesc94e2b52008-01-14 04:13:37 +00004090- sys.float_info / PyFloat_GetInfo: The floating point information
4091 object was converted from a dict to a specialized structseq object.
4092
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093- Patch #1816: Added sys.flags structseq. It exposes the status of
4094 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004095
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096- Objects/structseq.c: Implemented new structseq representation. The
4097 patch makes structseqs (e.g. the return value of os.stat) more
4098 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Patch #1700288: added a type attribute cache that caches method
4101 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004102
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004103- Bug #1776: __import__() no longer accepts filenames on any platform.
4104 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004105
Georg Brandlaed6c662008-01-07 17:25:53 +00004106- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4107
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4109 envvar and sys.dont_write_bytecode attribute. All these can be set
4110 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Improve some exception messages when Windows fails to load an
4113 extension module. Now we get for example '%1 is not a valid Win32
4114 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004115

Christian Heimes0a8143f2007-12-18 23:22:54 +00004121- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004122 and INF. float("nan"), float("inf") and float("-inf") now work on
4123 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Compiler now generates simpler and faster code for dictionary
4126 literals. The oparg for BUILD_MAP now indicates an estimated
4127 dictionary size. There is a new opcode, STORE_MAP, for adding
4128 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004157- Patch #1739468: Directories and zipfiles containing a __main__.py
4158 file can now be directly executed by passing their name to the
4159 interpreter. The directory/zipfile is automatically inserted as the
4160 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- Issue #1265: Fix a problem with sys.settrace, if the tracing
4163 function uses a generator expression when at the same time the
4164 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004165
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004166- sets and frozensets now have an isdisjoint() method.
4167
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004168- optimize the performance of builtin.sum().

4171
Georg Brandl21e99f42010-03-07 15:23:59 +00004172- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004173 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4174 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004175
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Issue #1686386: Tuple's tp_repr did not take into account the
4177 possibility of having a self-referential tuple, which is possible
4178 from C code. Nor did object's tp_str consider that a type's tp_str
4179 could do something that could lead to an inifinite recursion.
4180 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4181 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- Issue #1164: It was possible to trigger deadlock when using the
4184 'print' statement to write to a file since the GIL was not released
4185 as needed. Now PyObject_Print() does the right thing along with
4186 various tp_print implementations of the built-in types and those in
4187 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00004195
Brett Cannon1e534b52007-09-07 04:18:30 +00004196- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197 PyObject_Call() never calling back out to Python code to trigger
4198 recursion depth updates/checks. Required the creation of a static
4199 RuntimeError instance in case normalizing an exception put the
4200 recursion check value past its limit. Fixes crashers
4201 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004202

Neal Norwitz0ac60192007-05-27 04:08:54 +00004216- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217 __*__ attributes. (Some already existed, e.g., __doc__ and
4218 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004219
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004220- Add -3 option to the interpreter to warn about features that are

4222
Georg Brandl2134e752007-05-21 20:34:16 +00004223- Patch #1686487: you can now pass any mapping after '**' in function
4224 calls.
4225
Collin Winter62903052007-05-18 23:11:24 +00004226- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004227 "except E as target:". This is to provide forwards compatibility
4228 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004232- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004233 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004234
Vinay Sajip8549ce32007-05-06 17:53:37 +00004235- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004236 setting a plain string, ie don't expand to single letter identifiers.
4237
Raymond Hettinger13936692007-04-11 18:40:58 +00004238- Request #1191699: Slices can now be pickled.
4239
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004240- Request #1193128: str.translate() now allows a None argument for
4241 translations that only remove characters without re-mapping the
4242 remaining characters.
4243
Georg Brandl5cb76c12007-03-21 09:00:39 +00004244- Patch #1682205: a TypeError while unpacking an iterable is no longer
4245 masked by a generic one with the message "unpack non-sequence".
4246

4248
Guido van Rossum143b5642007-03-23 04:58:42 +00004249- Bug #1683368: The object.__init__() and object.__new__() methods are
4250 now stricter in rejecting excess arguments. The only time when
4251 either allows excess arguments is when it is not overridden and the
4252 other one is. For backwards compatibility, when both are
4253 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004254 warning later). Also, type.__init__() insists on the same signature
4255 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004257- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4258 object to complex using its __complex__() method before falling back
4259 to the __float__() method. Therefore, the functions in the cmath
4260 module now can operate on objects that define a __complex__()
4261 method.

4281
Georg Brandl871f1bc2007-03-12 13:17:36 +00004282- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283 its argument, if it exists. If not, it will work like before. This
4284 allows customizing the output of dir() in the presence of a
4285 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004297- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298 makes the filenames the warning module prints much more sensible
4299 when a PYTHONSTARTUP file is used.

4313 sq_ass_slice instead of the sq_slice slot.
4314
Georg Brandl3ee81df2008-05-17 18:14:43 +00004315- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00004367- Bug #1545497: when given an explicit base, int() did ignore NULs
4368 embedded in the string to convert.
4369
Georg Brandl846f73a2006-10-08 07:11:54 +00004370- Bug #1569998: break inside a try statement (outside a loop) is now
4371 recognized and rejected.
4372

Armin Rigo7ccbca92006-10-04 12:17:45 +00004375- A number of places, including integer negation and absolute value,
4376 were fixed to not rely on undefined behaviour of the C compiler
4377 anymore.

Georg Brandl4e933132006-09-06 20:05:58 +00004400- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
4401 Also make sure that every exception class has __module__ set to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004418 generator expressions (x for x, in ... ) works again. Fixing this
4419 problem required changing the .pyc magic number. This means that
4420 .pyc files generated before 2.5c2 will be regenerated.

5225 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00005226
Georg Brandl3ee81df2008-05-17 18:14:43 +00005227- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5228 with RFC 3207 and forgets any knowledge obtained from the server not
5229 obtained from the TLS negotiation itself. Patch contributed by Bill
5230 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005231
Georg Brandl3ee81df2008-05-17 18:14:43 +00005232- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005233 that the SMTP.starttls() caller no longer needs to call ehlo()
5234 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235 does not claim to support starttls. Adds the
5236 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5237 Fenner.

5306 contents before adding elements from the iterable. This fix brings
5307 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005308
Georg Brandl3ee81df2008-05-17 18:14:43 +00005309- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00005316- Marshal.dumps() now expects exact type matches for int, long, float,
5317 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5318 silently miscode subclasses of those types. Now, it raises a
5319 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005320

Georg Brandl3ee81df2008-05-17 18:14:43 +00005335 time so that opening a database previously created with the DB_DUP
5336 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5337 opens. Specifically: dictionary assignment to a DB object will
5338 replace all values for a given key when the database allows
5339 duplicate values. DB users should use DB.put(k, v) when they want
5340 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005341

5347 characters with ASCII value less than 32. Also, it correctly quotes
5348 dots only if they occur on a single line, as opposed to the previous
5349 behavior of quoting dots if they are the second character of any
5350 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005351
