Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000072- Issue #8329: Don't return the same lists from select.select when no fds are
73 changed.

86 is called with a non-empty format string. This is an effort to
87 future-proof user code. If a derived class does not currently
88 implement __format__ but later adds its own __format__, it would
89 most likely break user code that had supplied a format string. This
90 will be changed to a DeprecationWaring in Python 3.3 and it will be
91 an error in Python 3.4.
92
Antoine Pitroua57df2c2010-03-31 21:32:15 +000093- Issue #8268: Old-style classes (not just instances) now support weak

119 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
120 and `ssl.OPENSSL_VERSION_NUMBER`.
121

131
Raymond Hettingera551f312010-04-04 18:34:45 +0000132- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000133 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000134
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000135- The functools module also adds cmp_to_key() as a tool to transition

Mark Dickinsone096e822010-04-02 10:17:07 +0000141- Issue #7279: Comparisons involving a Decimal signaling NaN now
142 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000143 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
144 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000145
Mark Dickinson99d80962010-04-02 08:53:22 +0000146- Issue #2531: Comparison operations between floats and Decimal
147 instances now return a result based on the numeric values of the
148 operands; previously they returned an arbitrary result based on
149 the relative ordering of id(float) and id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000151- Issue #8233: When run as a script, py_compile.py optionally takes a single
152 argument `-` which tells it to read files to compile from stdin. Each line
153 is read on demand and the named file is compiled immediately. (Original
154 patch by Piotr Ożarowski).
155
156- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
157 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000158
Florent Xicluna58b65662010-03-30 16:29:03 +0000159- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
160 form feed (0x0C) are now considered linebreaks, as specified in Unicode
161 Standard Annex #14. See issue #7643.

Mark Dickinson9588d992010-03-27 11:14:37 +0000164- Comparisons using one of <, <=, >, >= between a complex instance and
165 a Fractions instance now raise TypeError instead of returning
166 True/False. This makes Fraction <=> complex comparisons consistent with
167 int <=> complex, float <=> complex, and complex <=> complex comparisons.
168
Michael Foorde6410c52010-03-29 20:04:23 +0000169- Addition of ``WeakSet`` to the ``weakref`` module.

189 method to LoggerAdapter.
190
Vinay Sajip31e928e2010-03-22 13:02:28 +0000191- Issue #8201: logging: Handle situation of non-ASCII and Unicode

Georg Brandlba83f822010-03-14 09:50:54 +0000223 for ``TimedRotatingFileHandler`` by using the modification time of an
224 existing log file to compute the next rollover time. If the log file does
225 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000226

236 a base64 transfer-encoded payload *after* decoding it; it no longer does.
237 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000264- Issue #8300: When passing a non-integer argument to struct.pack with any
265 integer format code, struct.pack first attempts to convert the non-integer
266 using its __index__ method. If that method is non-existent or raises
267 TypeError it goes on to try the __int__ method, as described below.
268
Georg Brandlba83f822010-03-14 09:50:54 +0000269- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
270 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
271 argument's __int__ method to convert to an integer before packing. It also
272 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
273 was inconsistent: __int__ was used for some integer codes but not for others,
274 and the set of integer codes for which it was used differed between native
275 packing and standard packing.)

530 including:
Mark Dickinson8efef5c2010-01-12 22:23:56 +0000531
Georg Brandlba83f822010-03-14 09:50:54 +0000532 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
533 strings,
534 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
535 numeric strings corresponding to subnormal values,
536 (3) a memory leak for some values large enough to cause overflow, and
537 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +0000573 file position when calling `truncate()`. It would previously change the file
574 position to the given argument, which goes against the tradition of

671Core and Builtins
672-----------------
673
Georg Brandlba83f822010-03-14 09:50:54 +0000674- The ``__complex__()`` method is now looked up on the class of instances to
675 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000677- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
678 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
679
Mark Dickinson1b34d252010-01-01 17:27:30 +0000680- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000681 DeprecationWarning when passed a float argument where an integer was expected.
682 These functions and methods now raise TypeError instead. The majority of the
683 effects of this change are in the extension modules, but some core functions
684 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
685 and many unicode/str methods.

697
Georg Brandlba83f822010-03-14 09:50:54 +0000698- Issue #1811: Improve accuracy and cross-platform consistency for true division
699 of integers: the result of a/b is now correctly rounded for ints a and b (at
700 least on IEEE 754 platforms), and in particular does not depend on the
701 internal representation of a long.

709
Georg Brandlba83f822010-03-14 09:50:54 +0000710 These executables now work properly with the arch(1) command: ``arch -ppc
711 python`` will start a universal binary version of python in PPC mode (unlike
712 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000868- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
869 decimal string that's guaranteed to round back to x under correct rounding
870 (with round-half-to-even rounding mode). Previously it gave a string based on
871 rounding x to 17 decimal digits. repr(x) for a complex number behaves
872 similarly. On platforms where the correctly-rounded strtod and dtoa code is
873 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000874
Georg Brandlba83f822010-03-14 09:50:54 +0000875- Issue #7117: On almost all platforms: float-to-string and string-to-float
876 conversions within Python are now correctly rounded. Places these conversions
877 occur include: str for floats and complex numbers; the float and complex
878 constructors; old-style and new-style numeric formatting; serialization and
879 deserialization of floats and complex numbers using marshal, pickle and json;
880 parsing of float and imaginary literals in Python code; Decimal-to-float
881 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000882
Georg Brandlba83f822010-03-14 09:50:54 +0000883 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
884 providing correctly-rounded strtod and dtoa C functions. This code is
885 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
886 the C compiler. There may be a small number of platforms on which correct
887 operation of this code cannot be guaranteed, so the code is not used: notably,
888 this applies to platforms where the C double format is not IEEE 754 binary64,
889 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
890 and Python's configure script is unable to determine how to change the FPU
891 precision. On these platforms conversions use the platform strtod and dtoa,
892 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000894- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
895 uses the correctly-rounded string <-> float conversions described above (when
896 available), and so produces correctly rounded results that will display nicely
897 under the float repr. There are two related small changes: (1) round now
898 accepts any class with an ``__index__()`` method for its second argument (but
899 no longer accepts floats for the second argument), and (2) an excessively
900 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
901 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001043
Georg Brandlba83f822010-03-14 09:50:54 +00001044 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1045 (2) parsing of strings representing infinities and nans was locale aware; and
1046 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001048- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1049 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1050 but with at least one decimal point and with a default precision
1051 of 12. Previously, the behavior the same but with a default precision of 6.
1052 This more closely matches ``str()``, and reduces surprises when adding
1053 alignment flags to the empty presentation type. This also affects the new
1054 complex.__format__ in the same way.
1055
1056- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1057 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001119 untrackable objects are not tracked by the garbage collector. This can reduce

1128 internal representation of integers, for performance reasons. Base 2**30 is
1129 enabled by default on 64-bit machines. Add --enable-big-digits option to

1254 the file object behaves like a closed file. The ``FileIO`` object also got a

Walter Dörwalded960ac2009-05-03 22:36:33 +00001306- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1307 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1308 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1309 of using the replace error handler in PyUnicode_DecodeUTF8().
1310
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001311- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001314- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1316 gives improved memory leak detection when running under Valgrind, while taking
1317 advantage of pymalloc at other times.

2681
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002682- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2683
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002684- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2685 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2686 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2687 ``printf`` function, whereas PyString_FromFormat has an independent
2688 implementation and uses "%zd" on all platforms for size_t values.
2689 This makes a difference on win64, where ``printf`` needs "%Id" to display
2690 64bit values.
2691
Benjamin Peterson97179b02008-09-09 20:55:01 +00002692- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2693 error.
2694
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002695- Issue #3777: long() applied to a float object now always return a long
2696 object; previously an int would be returned for small values. the __long__
2697 method is allowed to return either an int or a long, but the behaviour of
2698 float objects should not change to respect backward compatibility.
2699
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002700- Issue #3751: str.rpartition would perform a left-partition when called with
2701 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002706 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002707 was correctly parsed but parsing of subsequent arguments failed.
2708
Vinay Sajip35e3b032008-09-01 14:33:59 +00002709- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002710 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2711 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2712 when given a tuple of classes as second argument, were looking up
2713 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2714 type object.
2715
Neal Norwitz18aa3882008-08-24 05:04:52 +00002716- Fix crashes on memory allocation failure found with failmalloc.

2785 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2786 for catch_warnings() also led to an improvement in the raising of a
2787 DeprecationWarning related to warnings.warn_explicit().

2859-----------------
2860
Guido van Rossumf8402962008-08-20 15:01:50 +00002861- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2862 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2863 extensions do not automatically benefit from the class attribute
2864 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2865 to their tp_flags field if they care. This is a backwards
2866 compatibility feature; in 3.0, all types will use the cache by
2867 default.
2868
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002869- Keyword arguments can now follow starred arguments. (``f(a, *args,
2870 keyword=23)`` is now valid syntax.)
2871
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002872- ctypes function pointers that are COM methods have a boolean True
2873 value again.
2874
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002875- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2876 by denying s# to parse objects that have a releasebuffer procedure,
2877 and introducing s*.
2878
Georg Brandl1e13ea92008-08-11 09:07:59 +00002879- Issue #3537: Fix an assertion failure when an empty but presized dict
2880 object was stored in the freelist.
2881
Mark Dickinsonb6467572008-08-04 21:30:09 +00002882- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2883 ValueError consistently across platforms.
2884
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002885- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2886 (64bit Unix, for example), unichr() would truncate its argument and return
2887 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2888
Neal Norwitze7d8be82008-07-31 17:17:14 +00002889- Apply security patches from Apple.
2890
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002891- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2892 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2893
Antoine Pitrou92f82162008-07-25 22:22:08 +00002894- Issue #1819: function calls with several named parameters are now on
2895 average 35% faster (as measured by pybench).
2896
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002897- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2898 the python debugger steps into a class statement: the free variables (local
2899 variables defined in an outer scope) would be deleted from the outer scope.
2900
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002901- Issue #2620: Overflow checking when allocating or reallocating memory
2902 was not always being done properly in some python types and extension
2903 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2904 all been updated to perform better checks and places in the code that
2905 would previously leak memory on the error path when such an allocation
2906 failed have been fixed.

2912
Benjamin Petersone977ad42008-08-20 01:42:01 +00002913- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2914 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2915
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002916- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2917 version reported by these tools does not necessarily follow the python
2918 version numbering scheme, so the module is less strict when parsing it.
2919
Nick Coghlanf70385a2008-08-18 12:42:46 +00002920- Issue #2235: Added Py3k warnings for types which will become unhashable
2921 under the stricter __hash__ inheritance rules in 3.0. Several types
2922 which did not meet the rules for hash invariants and were already
2923 unhashable in 3.0 have now been explicitly flagged as unhashable in
2924 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2925 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2926
Brett Cannon88f801d2008-08-18 00:46:22 +00002927- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2974 to _sre.compile() will now be rejected. This should not affect anybody
2975 since the re.compile() function never generates invalid re-bytecode.

2979 it wasn't initialized during instantiation.
2980
Brett Cannon3aa2a492008-08-06 22:28:09 +00002981- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2982 the reload() built-in has been removed.

2993 raised an AttributeError.
2994
Benjamin Peterson01a24322008-07-28 23:35:27 +00002995- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002996 asking for a specific length. This problem only affected files opened
2997 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002998

3039 interaction with the tp_hash slot (added in 2.6b2) are now documented
3040
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003041- Issue #643841: The language reference now provides more detailed
3042 coverage of the lookup process for special methods. The disclaimers
3043 regarding lack of coverage of new-style classes have also been

3048================================
3049
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003050*Release date: 17-Jul-2008*
3051
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003052Core and Builtins
3053-----------------
3054
Georg Brandl3e483f62008-07-16 22:57:41 +00003055- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3056 its methods now allow for items objects that can be converted to
3057 an integer using operator.index().
3058
Mark Dickinson64b7e502008-07-16 09:40:03 +00003059- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3060 produced a ValueError instead of giving the correct float.
3061
Eric Smitha5fa5a22008-07-16 00:11:49 +00003062- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3063 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3064
Mark Dickinson7103aa42008-07-15 19:08:33 +00003065- Issue #3008: the float type has a new instance method 'float.hex'
3066 and a new class method 'float.fromhex' to convert floating-point
3067 numbers to and from hexadecimal strings, respectively.
3068
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003069- Issue #2235: __hash__ is once again inherited by default. To allow
3070 collections.Hashable to remain meaningful in the presence of the
3071 default hash implementation (object.__hash__), it is now possible
3072 to explicit block inheritance of hash by setting __hash__=None at
3073 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3074 level.
3075
Nick Coghlanb028f502008-07-13 14:52:36 +00003076- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3077 the parent module cannot be found while performing an absolute import.
3078 This means that an incorrectly defined __package__ attribute will
3079 now only prevent relative imports in that module rather than causing
3080 all imports from that module to fail.
3081
Nick Coghlan14ff9942008-07-08 14:21:42 +00003082- Issue #2517: Allow unicode messages in Exceptions again by correctly
3083 bypassing the instance dictionary when looking up __unicode__ on
3084 new-style classes.
3085
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003086- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3087 set to a custom object whose write() method happens to install
3088 another file in sys.stdout.
3089
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003090- Issue #3088: Corrected a race condition in classes derived from
3091 threading.local: the first member set by a thread could be saved in
3092 another thread's dictionary.
3093
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003094- Issue #3004: Minor change to slice.indices(): the start and stop
3095 arguments are now treated identically, making the behaviour easier
3096 to describe and understand. For example, slice(None, -10,
3097 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3098 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3099 10, -1).
3100
Georg Brandl278fc502008-07-19 12:46:12 +00003101- Issue #3219: Calling a function with repeated keyword arguments,
3102 f(a=2, a=23), would not cause a syntax error. This was a regression
3103 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003104
Georg Brandl278fc502008-07-19 12:46:12 +00003105- Issue #2862: Make int and float freelist management consistent with
3106 other freelists. Changes their CompactFreeList apis into
3107 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003112- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3113 api functions without holding the GIL, which could lead to a fatal
3114 error when they failed.
3115
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003116- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003141- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3142 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003143 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003144 content-length. The problem had been corrected in the 2.4 branch, but never
3145 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003160- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3161 handling is now the same as that of other special attributes like __name__).
3162
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003163- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3552 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003553 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003554
3555 This is controlled by the configure argument ``--with-universal-archs``:
3556
3557 - ``--with-universal-archs=all``: install 4-way universal
3558
3559 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3560
3561 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3562
3563 This option should be used in combination with ``--enable-universalsdk=``.
3564
3565 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 +00003615- Issue #1631171: Re-implement the 'warnings' module in C (the
3616 original Python code has been kept as backup). This will allow for
3617 using the 'warning's machinery in such places as the parser where
3618 use of pure Python code is not possible. Both the ``showarning()``
3619 and ``formatwarning()`` gain an optional 'line' argument which is
3620 not called by default for backwards-compatibility reasons. Setting
3621 ``warnings.showwarning()`` to an implementation that lacks support
3622 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003685- Issue #2550: The approach used by client/server code for obtaining
3686 ports to listen on in network-oriented tests has been refined in an
3687 effort to facilitate running multiple instances of the entire
3688 regression test suite in parallel without issue.
3689 test_support.bind_port() has been fixed such that it will always
3690 return a unique port -- which wasn't always the case with the
3691 previous implementation, especially if socket options had been set
3692 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3693 new implementation of bind_port() will actually raise an exception
3694 if it is passed an AF_INET/SOCK_STREAM socket with either the
3695 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3696 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3697 the socket it's been passed. This currently only applies to
3698 Windows. This option prevents any other sockets from binding to the
3699 host/port we've bound to, thus removing the possibility of the
3700 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3701 when a second SOCK_STREAM socket binds and accepts to a host/port
3702 that's already been bound by another socket. The optional preferred
3703 port parameter to bind_port() has been removed. Under no
3704 circumstances should tests be hard coding ports!
3705
3706 test_support.find_unused_port() has also been introduced, which will
3707 pass a temporary socket object to bind_port() in order to obtain an
3708 unused port. The temporary socket object is then closed and
3709 deleted, and the port is returned. This method should only be used
3710 for obtaining an unused port in order to pass to an external program
3711 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3712 a parameter to a server-oriented class that doesn't give you direct
3713 access to the underlying socket used.
3714
3715 Finally, test_support.HOST has been introduced, which should be used
3716 for the host argument of any relevant socket calls (i.e. bind and
3717 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003718
3719 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003720 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003721 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3722 test_asynchat and test_socket_ssl.
3723
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724 It is now possible for multiple instances of the regression test
3725 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003779- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003780 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3781 Plane. This affected raw unicode literals and the
3782 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3783 this case, like normal unicode literals and the 'unicode-escape'
3784 codec.

4003
Eric Smitha73fbe72008-02-23 03:09:44 +00004004- Added the future_builtins module, which contains hex() and oct().

4006 compatible with the hex() and oct() builtins from Python 3.0. They
4007 differ slightly in their output formats from the existing, unchanged
4008 Python 2.6 builtins. The expected usage of the future_builtins
4009 module is:
4010 from future_builtins import hex, oct

4013 exponents for exponents with absolute value < 100. Follows C99
4014 standard. This is a change on Windows, which would use 3 digits.
4015 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4016 so that any alterations it does to the resulting string will be
4017 available in stringlib/formatter.h (for float.__format__).
4018
Eric Smith5a3c1352008-02-19 13:21:56 +00004019- Implemented PEP 3101, Advanced String Formatting. This adds a new
4020 builtin format(); a format() method for str and unicode; a
4021 __format__() method to object, str, unicode, int, long, float, and
4022 datetime; the class string.Formatter; and the C API
4023 PyObject_Format().
4024
Georg Brandl3ee81df2008-05-17 18:14:43 +00004025- Fixed several potential crashes, all caused by specially crafted
4026 __del__ methods exploiting objects in temporarily inconsistent
4027 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004036- Clear all free lists during a gc.collect() of the highest generation
4037 in order to allow pymalloc to free more arenas. Python may give back
4038 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004039
Georg Brandl3ee81df2008-05-17 18:14:43 +00004040- Issue #2045: Fix an infinite recursion triggered when printing a
4041 subclass of collections.defaultdict, if its default_factory is set
4042 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004043
Christian Heimesf75dbef2008-02-08 00:11:31 +00004044- Fixed a minor memory leak in dictobject.c. The content of the free
4045 list was not freed on interpreter shutdown.
4046
Georg Brandl21e99f42010-03-07 15:23:59 +00004047- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004048 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004049
Georg Brandl3ee81df2008-05-17 18:14:43 +00004050- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4051 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004052 to compact the internal free lists of pre-allocted ints and floats.
4053

Georg Brandl3ee81df2008-05-17 18:14:43 +00004070- Patch #1473257: generator objects gain a gi_code attribute. This is
4071 the same object as the func_code attribute of the function that
4072 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004073
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- Issue #1920: "while 0" statements were completely removed by the
4075 compiler, even in the presence of an "else" clause, which is
4076 supposed to be run when the condition is false. Now the compiler
4077 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004078
Guido van Rossumeead05f2008-01-24 18:21:02 +00004079- A few crashers fixed: weakref_in_del.py (issue #1377858);
4080 loosing_dict_ref.py (issue #1303614, test67.py);
4081 borrowed_ref_[34].py (not in tracker).
4082
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004083- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004084 suppressed while an extension is loaded by calling SetErrorMode in

4086
Georg Brandl3ee81df2008-05-17 18:14:43 +00004087- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004088 several extension methods and modules do not work without unicode
4089 support.
4090
Georg Brandl26543b12008-01-21 18:36:51 +00004091- Issue #1882: when compiling code from a string, encoding cookies in the

4095
Georg Brandl6caad7d2008-01-26 14:19:22 +00004096- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004097 added.
4098
Christian Heimesc94e2b52008-01-14 04:13:37 +00004099- sys.float_info / PyFloat_GetInfo: The floating point information
4100 object was converted from a dict to a specialized structseq object.
4101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Patch #1816: Added sys.flags structseq. It exposes the status of
4103 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004104
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- Objects/structseq.c: Implemented new structseq representation. The
4106 patch makes structseqs (e.g. the return value of os.stat) more
4107 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004108
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109- Patch #1700288: added a type attribute cache that caches method
4110 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004111
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004112- Bug #1776: __import__() no longer accepts filenames on any platform.

4118 envvar and sys.dont_write_bytecode attribute. All these can be set
4119 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Improve some exception messages when Windows fails to load an
4122 extension module. Now we get for example '%1 is not a valid Win32
4123 application' instead of 'error code 193'.

4180
Georg Brandl21e99f42010-03-07 15:23:59 +00004181- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4183 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Issue #1686386: Tuple's tp_repr did not take into account the
4186 possibility of having a self-referential tuple, which is possible
4187 from C code. Nor did object's tp_str consider that a type's tp_str
4188 could do something that could lead to an inifinite recursion.
4189 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4190 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Issue #1164: It was possible to trigger deadlock when using the
4193 'print' statement to write to a file since the GIL was not released
4194 as needed. Now PyObject_Print() does the right thing along with
4195 various tp_print implementations of the built-in types and those in
4196 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004206 PyObject_Call() never calling back out to Python code to trigger
4207 recursion depth updates/checks. Required the creation of a static
4208 RuntimeError instance in case normalizing an exception put the
4209 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00004253- Patch #1682205: a TypeError while unpacking an iterable is no longer
4254 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00004258- Bug #1683368: The object.__init__() and object.__new__() methods are
4259 now stricter in rejecting excess arguments. The only time when
4260 either allows excess arguments is when it is not overridden and the
4261 other one is. For backwards compatibility, when both are
4262 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004263 warning later). Also, type.__init__() insists on the same signature
4264 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4267 object to complex using its __complex__() method before falling back
4268 to the __float__() method. Therefore, the functions in the cmath
4269 module now can operate on objects that define a __complex__()
4270 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004288- Bug #1678647: write a newline after printing an exception in any
4289 case, even when converting the value to a string failed.
4290
Georg Brandl871f1bc2007-03-12 13:17:36 +00004291- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004292 its argument, if it exists. If not, it will work like before. This
4293 allows customizing the output of dir() in the presence of a
4294 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004306- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307 makes the filenames the warning module prints much more sensible
4308 when a PYTHONSTARTUP file is used.

4322 sq_ass_slice instead of the sq_slice slot.
4323
Georg Brandl3ee81df2008-05-17 18:14:43 +00004324- When printing an unraisable error, don't print exceptions. before

4335 created a weakref on itself during a __del__ call for new-style
4336 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00004376- Bug #1545497: when given an explicit base, int() did ignore NULs
4377 embedded in the string to convert.
4378
Georg Brandl846f73a2006-10-08 07:11:54 +00004379- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004427 generator expressions (x for x, in ... ) works again. Fixing this
4428 problem required changing the .pyc magic number. This means that
4429 .pyc files generated before 2.5c2 will be regenerated.

5230 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00005231
Georg Brandl3ee81df2008-05-17 18:14:43 +00005232- The implementation of UnicodeError objects has been simplified
5233 (start and end attributes are now stored directly as Py_ssize_t
5234 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00005235
Georg Brandl3ee81df2008-05-17 18:14:43 +00005236- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5237 with RFC 3207 and forgets any knowledge obtained from the server not
5238 obtained from the TLS negotiation itself. Patch contributed by Bill
5239 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005240
Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005242 that the SMTP.starttls() caller no longer needs to call ehlo()
5243 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005244 does not claim to support starttls. Adds the
5245 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5246 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005288- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00005289 works as expected. ``mmap.find`` also takes an optional ``end``
5290 parameter.

5315 contents before adding elements from the iterable. This fix brings
5316 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005317
Georg Brandl3ee81df2008-05-17 18:14:43 +00005318- Added wide char functions to msvcrt module: getwch, getwche, putwch

5324
Georg Brandl3ee81df2008-05-17 18:14:43 +00005325- Marshal.dumps() now expects exact type matches for int, long, float,
5326 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5327 silently miscode subclasses of those types. Now, it raises a
5328 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005329

Georg Brandl3ee81df2008-05-17 18:14:43 +00005344 time so that opening a database previously created with the DB_DUP
5345 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5346 opens. Specifically: dictionary assignment to a DB object will
5347 replace all values for a given key when the database allows
5348 duplicate values. DB users should use DB.put(k, v) when they want
5349 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005350

5356 characters with ASCII value less than 32. Also, it correctly quotes
5357 dots only if they occur on a single line, as opposed to the previous
5358 behavior of quoting dots if they are the second character of any
5359 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005360

Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- Removed the macfs module. It had been deprecated since Python 2.5.
5766 This lead to the deprecation of macostools.touched() as it relied
5767 solely on macfs and was a no-op under OS X.
