91 is called with a non-empty format string. This is an effort to
92 future-proof user code. If a derived class does not currently
93 implement __format__ but later adds its own __format__, it would
94 most likely break user code that had supplied a format string. This
95 will be changed to a DeprecationWaring in Python 3.3 and it will be
96 an error in Python 3.4.

124 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
125 and `ssl.OPENSSL_VERSION_NUMBER`.
126
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000127- Issue #8310: Allow dis to examine new style classes.
128
Mark Dickinson8a950712010-04-03 15:47:46 +0000129- Issue #8257: The Decimal construct now accepts a float instance

136
Raymond Hettingera551f312010-04-04 18:34:45 +0000137- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000138 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000139
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000140- The functools module also adds cmp_to_key() as a tool to transition

Mark Dickinsone096e822010-04-02 10:17:07 +0000146- Issue #7279: Comparisons involving a Decimal signaling NaN now
147 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000148 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
149 are now hashable; Decimal signaling NaNs remain unhashable.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000156- Issue #8233: When run as a script, py_compile.py optionally takes a single
157 argument `-` which tells it to read files to compile from stdin. Each line
158 is read on demand and the named file is compiled immediately. (Original
159 patch by Piotr Ożarowski).
160
161- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
162 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000163

Mark Dickinson9588d992010-03-27 11:14:37 +0000169- Comparisons using one of <, <=, >, >= between a complex instance and
170 a Fractions instance now raise TypeError instead of returning
171 True/False. This makes Fraction <=> complex comparisons consistent with
172 int <=> complex, float <=> complex, and complex <=> complex comparisons.
173
Michael Foorde6410c52010-03-29 20:04:23 +0000174- Addition of ``WeakSet`` to the ``weakref`` module.

185 now silenced.
186
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000187- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

194 method to LoggerAdapter.
195
Vinay Sajip31e928e2010-03-22 13:02:28 +0000196- Issue #8201: logging: Handle situation of non-ASCII and Unicode
197 logger names existing at the same time, causing a Unicode error
198 when configuration code attempted to sort the existing loggers.

Georg Brandlba83f822010-03-14 09:50:54 +0000228 for ``TimedRotatingFileHandler`` by using the modification time of an
229 existing log file to compute the next rollover time. If the log file does
230 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000231

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

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000269- Issue #8300: When passing a non-integer argument to struct.pack with any
270 integer format code, struct.pack first attempts to convert the non-integer
271 using its __index__ method. If that method is non-existent or raises
272 TypeError it goes on to try the __int__ method, as described below.
273
Georg Brandlba83f822010-03-14 09:50:54 +0000274- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
275 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
276 argument's __int__ method to convert to an integer before packing. It also
277 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
278 was inconsistent: __int__ was used for some integer codes but not for others,
279 and the set of integer codes for which it was used differed between native
280 packing and standard packing.)

676Core and Builtins
677-----------------
678
Georg Brandlba83f822010-03-14 09:50:54 +0000679- The ``__complex__()`` method is now looked up on the class of instances to
680 make it consistent with other special methods.

684
Mark Dickinson1b34d252010-01-01 17:27:30 +0000685- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000686 DeprecationWarning when passed a float argument where an integer was expected.
687 These functions and methods now raise TypeError instead. The majority of the
688 effects of this change are in the extension modules, but some core functions
689 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
690 and many unicode/str methods.

702
Georg Brandlba83f822010-03-14 09:50:54 +0000703- Issue #1811: Improve accuracy and cross-platform consistency for true division
704 of integers: the result of a/b is now correctly rounded for ints a and b (at
705 least on IEEE 754 platforms), and in particular does not depend on the
706 internal representation of a long.

714
Georg Brandlba83f822010-03-14 09:50:54 +0000715 These executables now work properly with the arch(1) command: ``arch -ppc
716 python`` will start a universal binary version of python in PPC mode (unlike
717 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000873- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
874 decimal string that's guaranteed to round back to x under correct rounding
875 (with round-half-to-even rounding mode). Previously it gave a string based on
876 rounding x to 17 decimal digits. repr(x) for a complex number behaves
877 similarly. On platforms where the correctly-rounded strtod and dtoa code is
878 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000879
Georg Brandlba83f822010-03-14 09:50:54 +0000880- Issue #7117: On almost all platforms: float-to-string and string-to-float
881 conversions within Python are now correctly rounded. Places these conversions
882 occur include: str for floats and complex numbers; the float and complex
883 constructors; old-style and new-style numeric formatting; serialization and
884 deserialization of floats and complex numbers using marshal, pickle and json;
885 parsing of float and imaginary literals in Python code; Decimal-to-float
886 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000887
Georg Brandlba83f822010-03-14 09:50:54 +0000888 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
889 providing correctly-rounded strtod and dtoa C functions. This code is
890 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
891 the C compiler. There may be a small number of platforms on which correct
892 operation of this code cannot be guaranteed, so the code is not used: notably,
893 this applies to platforms where the C double format is not IEEE 754 binary64,
894 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
895 and Python's configure script is unable to determine how to change the FPU
896 precision. On these platforms conversions use the platform strtod and dtoa,
897 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000899- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
900 uses the correctly-rounded string <-> float conversions described above (when
901 available), and so produces correctly rounded results that will display nicely
902 under the float repr. There are two related small changes: (1) round now
903 accepts any class with an ``__index__()`` method for its second argument (but
904 no longer accepts floats for the second argument), and (2) an excessively
905 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
906 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001049 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1050 (2) parsing of strings representing infinities and nans was locale aware; and
1051 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001053- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1054 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1055 but with at least one decimal point and with a default precision
1056 of 12. Previously, the behavior the same but with a default precision of 6.
1057 This more closely matches ``str()``, and reduces surprises when adding
1058 alignment flags to the empty presentation type. This also affects the new
1059 complex.__format__ in the same way.

1259 the file object behaves like a closed file. The ``FileIO`` object also got a

Walter Dörwalded960ac2009-05-03 22:36:33 +00001311- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1312 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1313 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1314 of using the replace error handler in PyUnicode_DecodeUTF8().

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001316- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001319- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1321 gives improved memory leak detection when running under Valgrind, while taking
1322 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002687- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2688
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002689- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2690 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2691 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2692 ``printf`` function, whereas PyString_FromFormat has an independent
2693 implementation and uses "%zd" on all platforms for size_t values.
2694 This makes a difference on win64, where ``printf`` needs "%Id" to display
2695 64bit values.
2696
Benjamin Peterson97179b02008-09-09 20:55:01 +00002697- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2698 error.
2699
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002700- Issue #3777: long() applied to a float object now always return a long
2701 object; previously an int would be returned for small values. the __long__
2702 method is allowed to return either an int or a long, but the behaviour of
2703 float objects should not change to respect backward compatibility.
2704
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002705- Issue #3751: str.rpartition would perform a left-partition when called with
2706 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002711 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002712 was correctly parsed but parsing of subsequent arguments failed.
2713
Vinay Sajip35e3b032008-09-01 14:33:59 +00002714- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002715 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2716 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2717 when given a tuple of classes as second argument, were looking up
2718 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2719 type object.
2720
Neal Norwitz18aa3882008-08-24 05:04:52 +00002721- Fix crashes on memory allocation failure found with failmalloc.

2790 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2791 for catch_warnings() also led to an improvement in the raising of a
2792 DeprecationWarning related to warnings.warn_explicit().

2864-----------------
2865
Guido van Rossumf8402962008-08-20 15:01:50 +00002866- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2867 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2868 extensions do not automatically benefit from the class attribute
2869 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2870 to their tp_flags field if they care. This is a backwards
2871 compatibility feature; in 3.0, all types will use the cache by
2872 default.
2873
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002874- Keyword arguments can now follow starred arguments. (``f(a, *args,
2875 keyword=23)`` is now valid syntax.)
2876
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002877- ctypes function pointers that are COM methods have a boolean True
2878 value again.
2879
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002880- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2881 by denying s# to parse objects that have a releasebuffer procedure,
2882 and introducing s*.
2883
Georg Brandl1e13ea92008-08-11 09:07:59 +00002884- Issue #3537: Fix an assertion failure when an empty but presized dict
2885 object was stored in the freelist.
2886
Mark Dickinsonb6467572008-08-04 21:30:09 +00002887- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2888 ValueError consistently across platforms.
2889
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002890- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2891 (64bit Unix, for example), unichr() would truncate its argument and return
2892 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2893
Neal Norwitze7d8be82008-07-31 17:17:14 +00002894- Apply security patches from Apple.
2895
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002896- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2897 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2898
Antoine Pitrou92f82162008-07-25 22:22:08 +00002899- Issue #1819: function calls with several named parameters are now on
2900 average 35% faster (as measured by pybench).
2901
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002902- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2903 the python debugger steps into a class statement: the free variables (local
2904 variables defined in an outer scope) would be deleted from the outer scope.
2905
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002906- Issue #2620: Overflow checking when allocating or reallocating memory
2907 was not always being done properly in some python types and extension
2908 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2909 all been updated to perform better checks and places in the code that
2910 would previously leak memory on the error path when such an allocation
2911 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002916- Issue #3612: Added some missing basic types in ctypes.wintypes.
2917
Benjamin Petersone977ad42008-08-20 01:42:01 +00002918- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2919 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2920
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002921- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2922 version reported by these tools does not necessarily follow the python
2923 version numbering scheme, so the module is less strict when parsing it.
2924
Nick Coghlanf70385a2008-08-18 12:42:46 +00002925- Issue #2235: Added Py3k warnings for types which will become unhashable
2926 under the stricter __hash__ inheritance rules in 3.0. Several types
2927 which did not meet the rules for hash invariants and were already
2928 unhashable in 3.0 have now been explicitly flagged as unhashable in
2929 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2930 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2931
Brett Cannon88f801d2008-08-18 00:46:22 +00002932- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2979 to _sre.compile() will now be rejected. This should not affect anybody
2980 since the re.compile() function never generates invalid re-bytecode.

2984 it wasn't initialized during instantiation.
2985
Brett Cannon3aa2a492008-08-06 22:28:09 +00002986- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2987 the reload() built-in has been removed.

2998 raised an AttributeError.
2999
Benjamin Peterson01a24322008-07-28 23:35:27 +00003000- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003001 asking for a specific length. This problem only affected files opened
3002 using the new "io" module, not the built-in open() function.

3028 file name rather than a ZipInfo instance, so files are extracted with
3029 mode 0600 rather than 000 under Unix.
3030
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003031- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3044 interaction with the tp_hash slot (added in 2.6b2) are now documented
3045
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003046- Issue #643841: The language reference now provides more detailed
3047 coverage of the lookup process for special methods. The disclaimers
3048 regarding lack of coverage of new-style classes have also been

3053================================
3054
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003055*Release date: 17-Jul-2008*
3056
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003057Core and Builtins
3058-----------------
3059
Georg Brandl3e483f62008-07-16 22:57:41 +00003060- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3061 its methods now allow for items objects that can be converted to
3062 an integer using operator.index().
3063
Mark Dickinson64b7e502008-07-16 09:40:03 +00003064- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3065 produced a ValueError instead of giving the correct float.
3066
Eric Smitha5fa5a22008-07-16 00:11:49 +00003067- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3068 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3069
Mark Dickinson7103aa42008-07-15 19:08:33 +00003070- Issue #3008: the float type has a new instance method 'float.hex'
3071 and a new class method 'float.fromhex' to convert floating-point
3072 numbers to and from hexadecimal strings, respectively.
3073
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003074- Issue #2235: __hash__ is once again inherited by default. To allow
3075 collections.Hashable to remain meaningful in the presence of the
3076 default hash implementation (object.__hash__), it is now possible
3077 to explicit block inheritance of hash by setting __hash__=None at
3078 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3079 level.
3080
Nick Coghlanb028f502008-07-13 14:52:36 +00003081- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3082 the parent module cannot be found while performing an absolute import.
3083 This means that an incorrectly defined __package__ attribute will
3084 now only prevent relative imports in that module rather than causing
3085 all imports from that module to fail.
3086
Nick Coghlan14ff9942008-07-08 14:21:42 +00003087- Issue #2517: Allow unicode messages in Exceptions again by correctly
3088 bypassing the instance dictionary when looking up __unicode__ on
3089 new-style classes.
3090
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003091- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3092 set to a custom object whose write() method happens to install
3093 another file in sys.stdout.
3094
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003095- Issue #3088: Corrected a race condition in classes derived from
3096 threading.local: the first member set by a thread could be saved in
3097 another thread's dictionary.
3098
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003099- Issue #3004: Minor change to slice.indices(): the start and stop
3100 arguments are now treated identically, making the behaviour easier
3101 to describe and understand. For example, slice(None, -10,
3102 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3103 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3104 10, -1).
3105
Georg Brandl278fc502008-07-19 12:46:12 +00003106- Issue #3219: Calling a function with repeated keyword arguments,
3107 f(a=2, a=23), would not cause a syntax error. This was a regression
3108 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003109
Georg Brandl278fc502008-07-19 12:46:12 +00003110- Issue #2862: Make int and float freelist management consistent with
3111 other freelists. Changes their CompactFreeList apis into
3112 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003117- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3118 api functions without holding the GIL, which could lead to a fatal
3119 error when they failed.
3120
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003121- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003146- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3147 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003148 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003149 content-length. The problem had been corrected in the 2.4 branch, but never
3150 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003165- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3166 handling is now the same as that of other special attributes like __name__).
3167
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003168- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3557 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003558 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003559
3560 This is controlled by the configure argument ``--with-universal-archs``:
3561
3562 - ``--with-universal-archs=all``: install 4-way universal
3563
3564 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3565
3566 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3567
3568 This option should be used in combination with ``--enable-universalsdk=``.
3569
3570 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 +00003620- Issue #1631171: Re-implement the 'warnings' module in C (the
3621 original Python code has been kept as backup). This will allow for
3622 using the 'warning's machinery in such places as the parser where
3623 use of pure Python code is not possible. Both the ``showarning()``
3624 and ``formatwarning()`` gain an optional 'line' argument which is
3625 not called by default for backwards-compatibility reasons. Setting
3626 ``warnings.showwarning()`` to an implementation that lacks support
3627 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Issue #2550: The approach used by client/server code for obtaining
3691 ports to listen on in network-oriented tests has been refined in an
3692 effort to facilitate running multiple instances of the entire
3693 regression test suite in parallel without issue.
3694 test_support.bind_port() has been fixed such that it will always
3695 return a unique port -- which wasn't always the case with the
3696 previous implementation, especially if socket options had been set
3697 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3698 new implementation of bind_port() will actually raise an exception
3699 if it is passed an AF_INET/SOCK_STREAM socket with either the
3700 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3701 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3702 the socket it's been passed. This currently only applies to
3703 Windows. This option prevents any other sockets from binding to the
3704 host/port we've bound to, thus removing the possibility of the
3705 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3706 when a second SOCK_STREAM socket binds and accepts to a host/port
3707 that's already been bound by another socket. The optional preferred
3708 port parameter to bind_port() has been removed. Under no
3709 circumstances should tests be hard coding ports!
3710
3711 test_support.find_unused_port() has also been introduced, which will
3712 pass a temporary socket object to bind_port() in order to obtain an
3713 unused port. The temporary socket object is then closed and
3714 deleted, and the port is returned. This method should only be used
3715 for obtaining an unused port in order to pass to an external program
3716 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3717 a parameter to a server-oriented class that doesn't give you direct
3718 access to the underlying socket used.
3719
3720 Finally, test_support.HOST has been introduced, which should be used
3721 for the host argument of any relevant socket calls (i.e. bind and
3722 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003723
3724 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003726 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3727 test_asynchat and test_socket_ssl.
3728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 It is now possible for multiple instances of the regression test
3730 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003784- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003785 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3786 Plane. This affected raw unicode literals and the
3787 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3788 this case, like normal unicode literals and the 'unicode-escape'
3789 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00004009- Added the future_builtins module, which contains hex() and oct().

4011 compatible with the hex() and oct() builtins from Python 3.0. They
4012 differ slightly in their output formats from the existing, unchanged
4013 Python 2.6 builtins. The expected usage of the future_builtins
4014 module is:
4015 from future_builtins import hex, oct

4018 exponents for exponents with absolute value < 100. Follows C99
4019 standard. This is a change on Windows, which would use 3 digits.
4020 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4021 so that any alterations it does to the resulting string will be
4022 available in stringlib/formatter.h (for float.__format__).
4023
Eric Smith5a3c1352008-02-19 13:21:56 +00004024- Implemented PEP 3101, Advanced String Formatting. This adds a new
4025 builtin format(); a format() method for str and unicode; a
4026 __format__() method to object, str, unicode, int, long, float, and
4027 datetime; the class string.Formatter; and the C API
4028 PyObject_Format().
4029
Georg Brandl3ee81df2008-05-17 18:14:43 +00004030- Fixed several potential crashes, all caused by specially crafted
4031 __del__ methods exploiting objects in temporarily inconsistent
4032 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Clear all free lists during a gc.collect() of the highest generation
4042 in order to allow pymalloc to free more arenas. Python may give back
4043 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Issue #2045: Fix an infinite recursion triggered when printing a
4046 subclass of collections.defaultdict, if its default_factory is set
4047 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00004049- Fixed a minor memory leak in dictobject.c. The content of the free
4050 list was not freed on interpreter shutdown.
4051
Georg Brandl21e99f42010-03-07 15:23:59 +00004052- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004054
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4056 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- Patch #1473257: generator objects gain a gi_code attribute. This is
4076 the same object as the func_code attribute of the function that
4077 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004078
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Issue #1920: "while 0" statements were completely removed by the
4080 compiler, even in the presence of an "else" clause, which is
4081 supposed to be run when the condition is false. Now the compiler
4082 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004083
Guido van Rossumeead05f2008-01-24 18:21:02 +00004084- A few crashers fixed: weakref_in_del.py (issue #1377858);

4086 borrowed_ref_[34].py (not in tracker).
4087
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004088- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004089 suppressed while an extension is loaded by calling SetErrorMode in

4091
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004093 several extension methods and modules do not work without unicode
4094 support.
4095
Georg Brandl26543b12008-01-21 18:36:51 +00004096- Issue #1882: when compiling code from a string, encoding cookies in the

4100
Georg Brandl6caad7d2008-01-26 14:19:22 +00004101- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004102 added.
4103
Christian Heimesc94e2b52008-01-14 04:13:37 +00004104- sys.float_info / PyFloat_GetInfo: The floating point information
4105 object was converted from a dict to a specialized structseq object.
4106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Patch #1816: Added sys.flags structseq. It exposes the status of
4108 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004109
Georg Brandl3ee81df2008-05-17 18:14:43 +00004110- Objects/structseq.c: Implemented new structseq representation. The
4111 patch makes structseqs (e.g. the return value of os.stat) more
4112 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Patch #1700288: added a type attribute cache that caches method
4115 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004116
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004117- Bug #1776: __import__() no longer accepts filenames on any platform.

4123 envvar and sys.dont_write_bytecode attribute. All these can be set
4124 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004125
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Improve some exception messages when Windows fails to load an
4127 extension module. Now we get for example '%1 is not a valid Win32
4128 application' instead of 'error code 193'.

4185
Georg Brandl21e99f42010-03-07 15:23:59 +00004186- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4188 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #1686386: Tuple's tp_repr did not take into account the
4191 possibility of having a self-referential tuple, which is possible
4192 from C code. Nor did object's tp_str consider that a type's tp_str
4193 could do something that could lead to an inifinite recursion.
4194 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4195 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Issue #1164: It was possible to trigger deadlock when using the
4198 'print' statement to write to a file since the GIL was not released
4199 as needed. Now PyObject_Print() does the right thing along with
4200 various tp_print implementations of the built-in types and those in
4201 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004211 PyObject_Call() never calling back out to Python code to trigger
4212 recursion depth updates/checks. Required the creation of a static

Georg Brandl5cb76c12007-03-21 09:00:39 +00004258- Patch #1682205: a TypeError while unpacking an iterable is no longer
4259 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00004263- Bug #1683368: The object.__init__() and object.__new__() methods are
4264 now stricter in rejecting excess arguments. The only time when
4265 either allows excess arguments is when it is not overridden and the
4266 other one is. For backwards compatibility, when both are
4267 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004268 warning later). Also, type.__init__() insists on the same signature
4269 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4272 object to complex using its __complex__() method before falling back
4273 to the __float__() method. Therefore, the functions in the cmath
4274 module now can operate on objects that define a __complex__()
4275 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004293- Bug #1678647: write a newline after printing an exception in any
4294 case, even when converting the value to a string failed.
4295
Georg Brandl871f1bc2007-03-12 13:17:36 +00004296- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004297 its argument, if it exists. If not, it will work like before. This
4298 allows customizing the output of dir() in the presence of a
4299 __getattr__().

4309 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004310
Georg Brandlaa2321b2007-03-07 00:40:28 +00004311- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312 makes the filenames the warning module prints much more sensible
4313 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004326- Patch #1674228: when assigning a slice (old-style), check for the
4327 sq_ass_slice instead of the sq_slice slot.
4328
Georg Brandl3ee81df2008-05-17 18:14:43 +00004329- When printing an unraisable error, don't print exceptions. before
4330 the name. This duplicates the behavior whening normally printing
4331 exceptions.

4340 created a weakref on itself during a __del__ call for new-style
4341 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00004381- Bug #1545497: when given an explicit base, int() did ignore NULs
4382 embedded in the string to convert.
4383
Georg Brandl846f73a2006-10-08 07:11:54 +00004384- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004432 generator expressions (x for x, in ... ) works again. Fixing this
4433 problem required changing the .pyc magic number. This means that
4434 .pyc files generated before 2.5c2 will be regenerated.

5235 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00005236
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237- The implementation of UnicodeError objects has been simplified
5238 (start and end attributes are now stored directly as Py_ssize_t
5239 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5242 with RFC 3207 and forgets any knowledge obtained from the server not
5243 obtained from the TLS negotiation itself. Patch contributed by Bill
5244 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005245
Georg Brandl3ee81df2008-05-17 18:14:43 +00005246- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005247 that the SMTP.starttls() caller no longer needs to call ehlo()
5248 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005249 does not claim to support starttls. Adds the
5250 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5251 Fenner.

5320 contents before adding elements from the iterable. This fix brings
5321 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005322
Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00005330- Marshal.dumps() now expects exact type matches for int, long, float,
5331 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5332 silently miscode subclasses of those types. Now, it raises a
5333 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005334

Georg Brandl3ee81df2008-05-17 18:14:43 +00005349 time so that opening a database previously created with the DB_DUP
5350 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5351 opens. Specifically: dictionary assignment to a DB object will
5352 replace all values for a given key when the database allows
5353 duplicate values. DB users should use DB.put(k, v) when they want
5354 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005355

5361 characters with ASCII value less than 32. Also, it correctly quotes
5362 dots only if they occur on a single line, as opposed to the previous
5363 behavior of quoting dots if they are the second character of any
5364 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005365

Georg Brandl3ee81df2008-05-17 18:14:43 +00005770- Removed the macfs module. It had been deprecated since Python 2.5.
5771 This lead to the deprecation of macostools.touched() as it relied
5772 solely on macfs and was a no-op under OS X.
