29 the string "python" as the *ident*. openlog() arguments are all optional
30 and keywords.
31
Antoine Pitroua5c4b552010-04-22 23:33:02 +000032- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
33 a non-infinite timeout. Also make that method friendlier with applications
34 wanting to continue using the socket in clear-text mode, by disabling
35 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

109
Eric Smithd44b2fc2010-04-02 12:30:56 +0000110- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
111 is called with a non-empty format string. This is an effort to
112 future-proof user code. If a derived class does not currently
113 implement __format__ but later adds its own __format__, it would
114 most likely break user code that had supplied a format string. This
115 will be changed to a DeprecationWaring in Python 3.3 and it will be
116 an error in Python 3.4.
117
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000118- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000132 (SIGINT). If an error occurs while importing the site module, the error is
133 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000134 module.

144 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
145 and `ssl.OPENSSL_VERSION_NUMBER`.
146

156
Raymond Hettingera551f312010-04-04 18:34:45 +0000157- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000158 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000159

Mark Dickinsone096e822010-04-02 10:17:07 +0000166- Issue #7279: Comparisons involving a Decimal signaling NaN now
167 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000168 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
169 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000170

177 argument `-` which tells it to read files to compile from stdin. Each line
178 is read on demand and the named file is compiled immediately. (Original
179 patch by Piotr Ożarowski).
180
181- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
182 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000183

Mark Dickinson9588d992010-03-27 11:14:37 +0000189- Comparisons using one of <, <=, >, >= between a complex instance and
190 a Fractions instance now raise TypeError instead of returning
191 True/False. This makes Fraction <=> complex comparisons consistent with
192 int <=> complex, float <=> complex, and complex <=> complex comparisons.

297 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
298 was inconsistent: __int__ was used for some integer codes but not for others,
299 and the set of integer codes for which it was used differed between native
300 packing and standard packing.)

696Core and Builtins
697-----------------
698
Georg Brandlba83f822010-03-14 09:50:54 +0000699- The ``__complex__()`` method is now looked up on the class of instances to
700 make it consistent with other special methods.

704
Mark Dickinson1b34d252010-01-01 17:27:30 +0000705- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000706 DeprecationWarning when passed a float argument where an integer was expected.
707 These functions and methods now raise TypeError instead. The majority of the
708 effects of this change are in the extension modules, but some core functions
709 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
710 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000723- Issue #1811: Improve accuracy and cross-platform consistency for true division
724 of integers: the result of a/b is now correctly rounded for ints a and b (at
725 least on IEEE 754 platforms), and in particular does not depend on the
726 internal representation of a long.

734
Georg Brandlba83f822010-03-14 09:50:54 +0000735 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +0000893- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
894 decimal string that's guaranteed to round back to x under correct rounding
895 (with round-half-to-even rounding mode). Previously it gave a string based on
896 rounding x to 17 decimal digits. repr(x) for a complex number behaves
897 similarly. On platforms where the correctly-rounded strtod and dtoa code is
898 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000899
Georg Brandlba83f822010-03-14 09:50:54 +0000900- Issue #7117: On almost all platforms: float-to-string and string-to-float
901 conversions within Python are now correctly rounded. Places these conversions
902 occur include: str for floats and complex numbers; the float and complex
903 constructors; old-style and new-style numeric formatting; serialization and
904 deserialization of floats and complex numbers using marshal, pickle and json;
905 parsing of float and imaginary literals in Python code; Decimal-to-float
906 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000907
Georg Brandlba83f822010-03-14 09:50:54 +0000908 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
909 providing correctly-rounded strtod and dtoa C functions. This code is
910 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
911 the C compiler. There may be a small number of platforms on which correct
912 operation of this code cannot be guaranteed, so the code is not used: notably,
913 this applies to platforms where the C double format is not IEEE 754 binary64,
914 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
915 and Python's configure script is unable to determine how to change the FPU
916 precision. On these platforms conversions use the platform strtod and dtoa,
917 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000919- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
920 uses the correctly-rounded string <-> float conversions described above (when
921 available), and so produces correctly rounded results that will display nicely
922 under the float repr. There are two related small changes: (1) round now
923 accepts any class with an ``__index__()`` method for its second argument (but
924 no longer accepts floats for the second argument), and (2) an excessively
925 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
926 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001068
Georg Brandlba83f822010-03-14 09:50:54 +00001069 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1070 (2) parsing of strings representing infinities and nans was locale aware; and
1071 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001072
Georg Brandlba83f822010-03-14 09:50:54 +00001073- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1074 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1075 but with at least one decimal point and with a default precision
1076 of 12. Previously, the behavior the same but with a default precision of 6.
1077 This more closely matches ``str()``, and reduces surprises when adding
1078 alignment flags to the empty presentation type. This also affects the new
1079 complex.__format__ in the same way.
1080
1081- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1082 classtype's, even if it was None. property now inserts the __doc__ into the
1083 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00001144 untrackable objects are not tracked by the garbage collector. This can reduce

1153 internal representation of integers, for performance reasons. Base 2**30 is
1154 enabled by default on 64-bit machines. Add --enable-big-digits option to
1155 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00001262- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1263 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1264 instances. On a typical machine this saves 3 bytes of memory (on average) per
1265 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001267- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1268 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1269 instead of throwing a MemoryError.
1270
Georg Brandlba83f822010-03-14 09:50:54 +00001271- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00001274- Issue #4367: Python would segfault during compiling when the unicodedata

1276
Georg Brandlba83f822010-03-14 09:50:54 +00001277- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1278 file objects with closefd=False. The file descriptor is still kept open but
1279 the file object behaves like a closed file. The ``FileIO`` object also got a
1280 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001282- Issue #4348: Some bytearray methods returned that didn't cause any change to

1284

1299
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001300- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001301 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001303- On windows, ``os.chdir()`` given unicode was not working if
1304 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1305 this code path is really executed because I cannot move to such directory on
1306 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001307
Georg Brandlba83f822010-03-14 09:50:54 +00001308- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1309 element is temporarily replaced with an equivalent frozenset. But the
1310 eventual KeyError would always report the empty ``frozenset()`` as the missing
1311 key. Now it correctly refers to the initial element.

1329 returned them on 64bit platforms.
1330
Walter Dörwalded960ac2009-05-03 22:36:33 +00001331- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1332 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1333 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1334 of using the replace error handler in PyUnicode_DecodeUTF8().
1335
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001336- Issue #3739: The unicode-internal encoder now reports the number of characters
1337 consumed like any other encoder (instead of the number of bytes).
1338
Georg Brandlba83f822010-03-14 09:50:54 +00001339- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1340 allocator will be automatically disabled when running under Valgrind. This
1341 gives improved memory leak detection when running under Valgrind, while taking
1342 advantage of pymalloc at other times.

2507 struct.error. Previously an x with an __int__ method could be packed by
2508 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2509 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2510 neither __int__ nor __long__, TypeError used to be raised (with a
2511 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2512 struct.error in other cases.

2515 argument with an __int__ method can be packed, but use of this feature

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002707- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2708
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002709- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2710 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2711 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2712 ``printf`` function, whereas PyString_FromFormat has an independent
2713 implementation and uses "%zd" on all platforms for size_t values.
2714 This makes a difference on win64, where ``printf`` needs "%Id" to display
2715 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002717- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2721 object; previously an int would be returned for small values. the __long__
2722 method is allowed to return either an int or a long, but the behaviour of
2723 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002725- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002731 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002732 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002734- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002735 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2736 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2737 when given a tuple of classes as second argument, were looking up
2738 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2739 type object.

2884-----------------
2885
Guido van Rossumf8402962008-08-20 15:01:50 +00002886- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2887 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2888 extensions do not automatically benefit from the class attribute
2889 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2890 to their tp_flags field if they care. This is a backwards
2891 compatibility feature; in 3.0, all types will use the cache by
2892 default.
2893
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002894- Keyword arguments can now follow starred arguments. (``f(a, *args,

2896
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002897- ctypes function pointers that are COM methods have a boolean True

2909
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002910- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2911 (64bit Unix, for example), unichr() would truncate its argument and return
2912 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00002914- Apply security patches from Apple.

2924 variables defined in an outer scope) would be deleted from the outer scope.
2925
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002926- Issue #2620: Overflow checking when allocating or reallocating memory
2927 was not always being done properly in some python types and extension
2928 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2929 all been updated to perform better checks and places in the code that
2930 would previously leak memory on the error path when such an allocation
2931 failed have been fixed.

2940
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002941- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2942 version reported by these tools does not necessarily follow the python
2943 version numbering scheme, so the module is less strict when parsing it.
2944
Nick Coghlanf70385a2008-08-18 12:42:46 +00002945- Issue #2235: Added Py3k warnings for types which will become unhashable
2946 under the stricter __hash__ inheritance rules in 3.0. Several types
2947 which did not meet the rules for hash invariants and were already
2948 unhashable in 3.0 have now been explicitly flagged as unhashable in
2949 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2950 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2951
Brett Cannon88f801d2008-08-18 00:46:22 +00002952- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2975
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002976- Issue #2676: in the email package, content-type parsing was hanging on

2984 since mimetools itself is deprecated. Because modules are cached, all
2985 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2986

2993 version that did not raise a DeprecationWarning under -3.
2994

2999 to _sre.compile() will now be rejected. This should not affect anybody
3000 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00003002- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3003 upon first access it can be automatically initialized from the csv file if
3004 it wasn't initialized during instantiation.
3005
Brett Cannon3aa2a492008-08-06 22:28:09 +00003006- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3007 the reload() built-in has been removed.
3008
Brett Cannon7e30b672008-08-04 21:52:25 +00003009- Changed code in the following modules/packages to remove warnings raised

3018 raised an AttributeError.
3019
Benjamin Peterson01a24322008-07-28 23:35:27 +00003020- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003021 asking for a specific length. This problem only affected files opened
3022 using the new "io" module, not the built-in open() function.

3046
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003047- Issue #3394: zipfile.writestr sets external attributes when passed a
3048 file name rather than a ZipInfo instance, so files are extracted with
3049 mode 0600 rather than 000 under Unix.
3050
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003051- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3052 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003063- Issue #2235: the C API function PyObject_HashNotImplemented and its
3064 interaction with the tp_hash slot (added in 2.6b2) are now documented
3065
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003066- Issue #643841: The language reference now provides more detailed
3067 coverage of the lookup process for special methods. The disclaimers
3068 regarding lack of coverage of new-style classes have also been
3069 removed, since the coverage is now fairly reasonable.

3073================================
3074
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003075*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003077Core and Builtins
3078-----------------
3079
Georg Brandl3e483f62008-07-16 22:57:41 +00003080- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3081 its methods now allow for items objects that can be converted to
3082 an integer using operator.index().
3083
Mark Dickinson64b7e502008-07-16 09:40:03 +00003084- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3085 produced a ValueError instead of giving the correct float.
3086
Eric Smitha5fa5a22008-07-16 00:11:49 +00003087- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3088 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3089
Mark Dickinson7103aa42008-07-15 19:08:33 +00003090- Issue #3008: the float type has a new instance method 'float.hex'
3091 and a new class method 'float.fromhex' to convert floating-point
3092 numbers to and from hexadecimal strings, respectively.
3093
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003094- Issue #2235: __hash__ is once again inherited by default. To allow
3095 collections.Hashable to remain meaningful in the presence of the
3096 default hash implementation (object.__hash__), it is now possible
3097 to explicit block inheritance of hash by setting __hash__=None at
3098 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3099 level.
3100
Nick Coghlanb028f502008-07-13 14:52:36 +00003101- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3102 the parent module cannot be found while performing an absolute import.
3103 This means that an incorrectly defined __package__ attribute will
3104 now only prevent relative imports in that module rather than causing
3105 all imports from that module to fail.
3106
Nick Coghlan14ff9942008-07-08 14:21:42 +00003107- Issue #2517: Allow unicode messages in Exceptions again by correctly
3108 bypassing the instance dictionary when looking up __unicode__ on
3109 new-style classes.
3110
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003111- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3112 set to a custom object whose write() method happens to install
3113 another file in sys.stdout.
3114
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003115- Issue #3088: Corrected a race condition in classes derived from
3116 threading.local: the first member set by a thread could be saved in
3117 another thread's dictionary.
3118
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003119- Issue #3004: Minor change to slice.indices(): the start and stop
3120 arguments are now treated identically, making the behaviour easier
3121 to describe and understand. For example, slice(None, -10,
3122 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3123 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3124 10, -1).
3125
Georg Brandl278fc502008-07-19 12:46:12 +00003126- Issue #3219: Calling a function with repeated keyword arguments,
3127 f(a=2, a=23), would not cause a syntax error. This was a regression
3128 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003129
Georg Brandl278fc502008-07-19 12:46:12 +00003130- Issue #2862: Make int and float freelist management consistent with
3131 other freelists. Changes their CompactFreeList apis into
3132 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003137- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3138 api functions without holding the GIL, which could lead to a fatal
3139 error when they failed.
3140
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003141- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3150 ForkingPickler.register() to resolve conflict with ctypes.
3151
Vinay Sajip51e65192008-07-18 09:01:10 +00003152- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00003157- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3158 incomplete structure was created.
3159

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003166- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3167 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003168 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003169 content-length. The problem had been corrected in the 2.4 branch, but never
3170 merged into trunk.
3171
Georg Brandle78fbcc2008-07-05 10:13:36 +00003172- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003185- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3186 handling is now the same as that of other special attributes like __name__).
3187
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003188- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00003578 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003579
3580 This is controlled by the configure argument ``--with-universal-archs``:
3581
3582 - ``--with-universal-archs=all``: install 4-way universal
3583
3584 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3585
3586 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3587
3588 This option should be used in combination with ``--enable-universalsdk=``.
3589
3590 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 +00003640- Issue #1631171: Re-implement the 'warnings' module in C (the
3641 original Python code has been kept as backup). This will allow for
3642 using the 'warning's machinery in such places as the parser where
3643 use of pure Python code is not possible. Both the ``showarning()``
3644 and ``formatwarning()`` gain an optional 'line' argument which is
3645 not called by default for backwards-compatibility reasons. Setting
3646 ``warnings.showwarning()`` to an implementation that lacks support
3647 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Issue #2550: The approach used by client/server code for obtaining
3711 ports to listen on in network-oriented tests has been refined in an
3712 effort to facilitate running multiple instances of the entire
3713 regression test suite in parallel without issue.
3714 test_support.bind_port() has been fixed such that it will always
3715 return a unique port -- which wasn't always the case with the
3716 previous implementation, especially if socket options had been set
3717 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3718 new implementation of bind_port() will actually raise an exception
3719 if it is passed an AF_INET/SOCK_STREAM socket with either the
3720 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3721 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3722 the socket it's been passed. This currently only applies to
3723 Windows. This option prevents any other sockets from binding to the
3724 host/port we've bound to, thus removing the possibility of the
3725 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3726 when a second SOCK_STREAM socket binds and accepts to a host/port
3727 that's already been bound by another socket. The optional preferred
3728 port parameter to bind_port() has been removed. Under no
3729 circumstances should tests be hard coding ports!
3730
3731 test_support.find_unused_port() has also been introduced, which will
3732 pass a temporary socket object to bind_port() in order to obtain an
3733 unused port. The temporary socket object is then closed and
3734 deleted, and the port is returned. This method should only be used
3735 for obtaining an unused port in order to pass to an external program
3736 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3737 a parameter to a server-oriented class that doesn't give you direct
3738 access to the underlying socket used.
3739
3740 Finally, test_support.HOST has been introduced, which should be used
3741 for the host argument of any relevant socket calls (i.e. bind and
3742 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003743
3744 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003746 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3747 test_asynchat and test_socket_ssl.
3748
Georg Brandl3ee81df2008-05-17 18:14:43 +00003749 It is now possible for multiple instances of the regression test
3750 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004019- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004020 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004021
Georg Brandlad61bc82008-02-23 15:11:18 +00004022- Issue #2067: file.__exit__() now calls subclasses' close() method.
4023
4024- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004025
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004026- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004027 issue 215555 for a discussion.
4028
Eric Smitha73fbe72008-02-23 03:09:44 +00004029- Added the future_builtins module, which contains hex() and oct().
4030 These are the PEP 3127 version of these functions, designed to be
4031 compatible with the hex() and oct() builtins from Python 3.0. They
4032 differ slightly in their output formats from the existing, unchanged
4033 Python 2.6 builtins. The expected usage of the future_builtins
4034 module is:
4035 from future_builtins import hex, oct
4036
Eric Smith7ef40bf2008-02-20 23:34:22 +00004037- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4038 exponents for exponents with absolute value < 100. Follows C99
4039 standard. This is a change on Windows, which would use 3 digits.
4040 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4041 so that any alterations it does to the resulting string will be
4042 available in stringlib/formatter.h (for float.__format__).
4043
Eric Smith5a3c1352008-02-19 13:21:56 +00004044- Implemented PEP 3101, Advanced String Formatting. This adds a new
4045 builtin format(); a format() method for str and unicode; a
4046 __format__() method to object, str, unicode, int, long, float, and
4047 datetime; the class string.Formatter; and the C API
4048 PyObject_Format().
4049
Georg Brandl3ee81df2008-05-17 18:14:43 +00004050- Fixed several potential crashes, all caused by specially crafted
4051 __del__ methods exploiting objects in temporarily inconsistent
4052 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004053
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004054- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055 prevent a possible crash: an Abstract Base Class would try to access
4056 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004057
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Fixed repr() and str() of complex numbers with infinity or nan as
4059 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Clear all free lists during a gc.collect() of the highest generation
4062 in order to allow pymalloc to free more arenas. Python may give back
4063 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Issue #2045: Fix an infinite recursion triggered when printing a
4066 subclass of collections.defaultdict, if its default_factory is set
4067 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004068
Christian Heimesf75dbef2008-02-08 00:11:31 +00004069- Fixed a minor memory leak in dictobject.c. The content of the free
4070 list was not freed on interpreter shutdown.
4071
Georg Brandl21e99f42010-03-07 15:23:59 +00004072- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004073 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004074
Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4076 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004077 to compact the internal free lists of pre-allocted ints and floats.
4078
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4080 calls. Python expected the return type int but the fork familie
4081 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004082
Georg Brandl3ee81df2008-05-17 18:14:43 +00004083- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4084 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004085
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4087 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004088
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4090 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004091
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4093 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004094
Georg Brandl3ee81df2008-05-17 18:14:43 +00004095- Patch #1473257: generator objects gain a gi_code attribute. This is
4096 the same object as the func_code attribute of the function that
4097 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004098
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099- Issue #1920: "while 0" statements were completely removed by the
4100 compiler, even in the presence of an "else" clause, which is
4101 supposed to be run when the condition is false. Now the compiler
4102 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004103
Guido van Rossumeead05f2008-01-24 18:21:02 +00004104- A few crashers fixed: weakref_in_del.py (issue #1377858);
4105 loosing_dict_ref.py (issue #1303614, test67.py);
4106 borrowed_ref_[34].py (not in tracker).
4107
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004108- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004109 suppressed while an extension is loaded by calling SetErrorMode in
4110 dynload_win.c. The error is still reported properly.
4111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004113 several extension methods and modules do not work without unicode
4114 support.
4115
Georg Brandl26543b12008-01-21 18:36:51 +00004116- Issue #1882: when compiling code from a string, encoding cookies in the
4117 second line of code were not always recognized correctly.
4118
Georg Brandl14404b62008-01-19 19:27:05 +00004119- Issue #1679: "0x" was taken as a valid integer literal.
4120
Georg Brandl6caad7d2008-01-26 14:19:22 +00004121- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004122 added.
4123
Christian Heimesc94e2b52008-01-14 04:13:37 +00004124- sys.float_info / PyFloat_GetInfo: The floating point information
4125 object was converted from a dict to a specialized structseq object.
4126
Georg Brandl3ee81df2008-05-17 18:14:43 +00004127- Patch #1816: Added sys.flags structseq. It exposes the status of
4128 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Objects/structseq.c: Implemented new structseq representation. The
4131 patch makes structseqs (e.g. the return value of os.stat) more
4132 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Patch #1700288: added a type attribute cache that caches method
4135 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004136
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004137- Bug #1776: __import__() no longer accepts filenames on any platform.
4138 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004139

4141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4143 envvar and sys.dont_write_bytecode attribute. All these can be set
4144 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004145
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146- Improve some exception messages when Windows fails to load an
4147 extension module. Now we get for example '%1 is not a valid Win32
4148 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004149
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4153 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004154
Christian Heimes0a8143f2007-12-18 23:22:54 +00004155- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156 and INF. float("nan"), float("inf") and float("-inf") now work on
4157 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Compiler now generates simpler and faster code for dictionary
4160 literals. The oparg for BUILD_MAP now indicates an estimated
4161 dictionary size. There is a new opcode, STORE_MAP, for adding
4162 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004163
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Issue #1538: Avoid copying string in split/rsplit if the split char
4170 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004171
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004172- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004173 SystemError.
4174
Nick Coghlanef01d822007-12-03 12:55:17 +00004175- PEP 366: Allow explicit relative imports when executing modules

4192 file can now be directly executed by passing their name to the
4193 interpreter. The directory/zipfile is automatically inserted as the
4194 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Issue #1265: Fix a problem with sys.settrace, if the tracing
4197 function uses a generator expression when at the same time the
4198 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004199
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004200- sets and frozensets now have an isdisjoint() method.
4201
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004202- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004204- Fix warnings found by the new version of the Coverity checker.
4205
Georg Brandl21e99f42010-03-07 15:23:59 +00004206- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4208 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Issue #1686386: Tuple's tp_repr did not take into account the
4211 possibility of having a self-referential tuple, which is possible
4212 from C code. Nor did object's tp_str consider that a type's tp_str
4213 could do something that could lead to an inifinite recursion.
4214 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4215 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Issue #1164: It was possible to trigger deadlock when using the
4218 'print' statement to write to a file since the GIL was not released
4219 as needed. Now PyObject_Print() does the right thing along with
4220 various tp_print implementations of the built-in types and those in
4221 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Issue #1147: Exceptions were directly allowing string exceptions in
4224 their throw() method even though string exceptions no longer
4225 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004226
Georg Brandl3ee81df2008-05-17 18:14:43 +00004227- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00004230- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231 PyObject_Call() never calling back out to Python code to trigger
4232 recursion depth updates/checks. Required the creation of a static
4233 RuntimeError instance in case normalizing an exception put the
4234 recursion check value past its limit. Fixes crashers
4235 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004236
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004250- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004251 __*__ attributes. (Some already existed, e.g., __doc__ and
4252 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004253
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004254- Add -3 option to the interpreter to warn about features that are
4255 deprecated and will be changed/removed in Python 3.0.
4256
Georg Brandl2134e752007-05-21 20:34:16 +00004257- Patch #1686487: you can now pass any mapping after '**' in function
4258 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004261 "except E as target:". This is to provide forwards compatibility
4262 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00004283- Bug #1683368: The object.__init__() and object.__new__() methods are
4284 now stricter in rejecting excess arguments. The only time when
4285 either allows excess arguments is when it is not overridden and the
4286 other one is. For backwards compatibility, when both are
4287 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004288 warning later). Also, type.__init__() insists on the same signature
4289 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004291- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4292 object to complex using its __complex__() method before falling back
4293 to the __float__() method. Therefore, the functions in the cmath
4294 module now can operate on objects that define a __complex__()
4295 method.

4315
Georg Brandl871f1bc2007-03-12 13:17:36 +00004316- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317 its argument, if it exists. If not, it will work like before. This
4318 allows customizing the output of dir() in the presence of a

4329 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00004331- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004332 makes the filenames the warning module prints much more sensible
4333 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004884 AttributeError instead of an IOError when the server's response

4976 TestCase and TestSuite subclasses (not instances) are no longer

4979 -- the failure just occurred later, with a more cumbersome
4980 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005261- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5262 with RFC 3207 and forgets any knowledge obtained from the server not
5263 obtained from the TLS negotiation itself. Patch contributed by Bill
5264 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005265
Georg Brandl3ee81df2008-05-17 18:14:43 +00005266- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005267 that the SMTP.starttls() caller no longer needs to call ehlo()
5268 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269 does not claim to support starttls. Adds the
5270 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5351 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5352 silently miscode subclasses of those types. Now, it raises a
5353 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005354

Georg Brandl3ee81df2008-05-17 18:14:43 +00005369 time so that opening a database previously created with the DB_DUP
5370 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5371 opens. Specifically: dictionary assignment to a DB object will
5372 replace all values for a given key when the database allows
5373 duplicate values. DB users should use DB.put(k, v) when they want
5374 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005375

5381 characters with ASCII value less than 32. Also, it correctly quotes
5382 dots only if they occur on a single line, as opposed to the previous
5383 behavior of quoting dots if they are the second character of any
5384 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005385

Georg Brandl3ee81df2008-05-17 18:14:43 +00005729- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5730 of w# format code incorrectly truncated the length to an int, even
5731 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5732 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005734- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5735 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5742 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005743
5744- Patch #1733960: Allow T_LONGLONG to accept ints.
5745
5746- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

5751
5752- Fix some leftovers from the conversion from int to Py_ssize_t
5753 (relevant to strings and sequences of more than 2**31 items).
5754
5755- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5756 outside of pystate.c and should not be necessary.
5757
Georg Brandl3ee81df2008-05-17 18:14:43 +00005758- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5759 absolute imports. In earlier versions they might have used relative
5760 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005761
Georg Brandl3ee81df2008-05-17 18:14:43 +00005762- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5763 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005764
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005772- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5773 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5774 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5775 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005790- Removed the macfs module. It had been deprecated since Python 2.5.
5791 This lead to the deprecation of macostools.touched() as it relied
5792 solely on macfs and was a no-op under OS X.
