Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000728- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
729 start byte and the continuation byte(s) are now considered invalid, instead
730 of the number of bytes specified by the start byte.
731 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
732 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
733 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

743 objects. (1) The comparison could incorrectly return True in some cases
744 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001622- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001623 file position when calling `truncate()`. It would previously change the file
1624 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001625 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1626
Georg Brandlba83f822010-03-14 09:50:54 +00001627- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1628 class used to represent files stored inside an archive. The new
1629 implementation is significantly faster and can be wrapped in a
1630 ``io.BufferedReader`` object for more speedups. It also solves an issue
1631 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001642- Issue #7748: Since unicode values are supported for some metadata options in

1644 encoded string for them. This ensures that the upload and register commands
1645 send the correct values to PyPI without any error.

1720-----------------
1721
Georg Brandlba83f822010-03-14 09:50:54 +00001722- The ``__complex__()`` method is now looked up on the class of instances to
1723 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001725- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1726 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1727
Mark Dickinson1b34d252010-01-01 17:27:30 +00001728- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001729 DeprecationWarning when passed a float argument where an integer was expected.
1730 These functions and methods now raise TypeError instead. The majority of the
1731 effects of this change are in the extension modules, but some core functions
1732 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1733 and many unicode/str methods.

1747 of integers: the result of a/b is now correctly rounded for ints a and b (at
1748 least on IEEE 754 platforms), and in particular does not depend on the
1749 internal representation of a long.

1757
Georg Brandlba83f822010-03-14 09:50:54 +00001758 These executables now work properly with the arch(1) command: ``arch -ppc
1759 python`` will start a universal binary version of python in PPC mode (unlike

1846 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
1847 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
1848 float arguments for integer format codes (other than 'L'): previously an
1849 attempt to pass a float resulted in a DeprecationWarning; now it gives a
1850 TypeError. For the 'L' format code (which previously had no warning) there is
1851 now a DeprecationWarning.

1900 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001901
Georg Brandlba83f822010-03-14 09:50:54 +00001902- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1903 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001915
Georg Brandlba83f822010-03-14 09:50:54 +00001916- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1917 decimal string that's guaranteed to round back to x under correct rounding
1918 (with round-half-to-even rounding mode). Previously it gave a string based on
1919 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1920 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1921 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001922
Georg Brandlba83f822010-03-14 09:50:54 +00001923- Issue #7117: On almost all platforms: float-to-string and string-to-float
1924 conversions within Python are now correctly rounded. Places these conversions
1925 occur include: str for floats and complex numbers; the float and complex
1926 constructors; old-style and new-style numeric formatting; serialization and
1927 deserialization of floats and complex numbers using marshal, pickle and json;
1928 parsing of float and imaginary literals in Python code; Decimal-to-float
1929 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001930
Georg Brandlba83f822010-03-14 09:50:54 +00001931 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1932 providing correctly-rounded strtod and dtoa C functions. This code is
1933 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1934 the C compiler. There may be a small number of platforms on which correct
1935 operation of this code cannot be guaranteed, so the code is not used: notably,
1936 this applies to platforms where the C double format is not IEEE 754 binary64,
1937 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1938 and Python's configure script is unable to determine how to change the FPU
1939 precision. On these platforms conversions use the platform strtod and dtoa,
1940 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001941
Georg Brandlba83f822010-03-14 09:50:54 +00001942- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1943 uses the correctly-rounded string <-> float conversions described above (when
1944 available), and so produces correctly rounded results that will display nicely
1945 under the float repr. There are two related small changes: (1) round now
1946 accepts any class with an ``__index__()`` method for its second argument (but
1947 no longer accepts floats for the second argument), and (2) an excessively
1948 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1949 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002091
Georg Brandlba83f822010-03-14 09:50:54 +00002092 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2093 (2) parsing of strings representing infinities and nans was locale aware; and
2094 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002096- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2097 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2098 but with at least one decimal point and with a default precision
2099 of 12. Previously, the behavior the same but with a default precision of 6.
2100 This more closely matches ``str()``, and reduces surprises when adding
2101 alignment flags to the empty presentation type. This also affects the new
2102 complex.__format__ in the same way.
2103
2104- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

2328 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00002331- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2332 element is temporarily replaced with an equivalent frozenset. But the
2333 eventual KeyError would always report the empty ``frozenset()`` as the missing
2334 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002354- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2355 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2356 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2357 of using the replace error handler in PyUnicode_DecodeUTF8().
2358
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002359- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002362- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2364 gives improved memory leak detection when running under Valgrind, while taking
2365 advantage of pymalloc at other times.

3531 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3532 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3533 neither __int__ nor __long__, TypeError used to be raised (with a
3534 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3535 struct.error in other cases.

3538 argument with an __int__ method can be packed, but use of this feature
3539 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00003588 leak-chasing test runs give sensible results. The previous method of reaping
3589 threads could return successfully while some Thread objects were still

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003711 AttributeError instead of RuntimeError, depending in which C API call
3712 exactly the recursion limit is exceeded. Consequently, both exception types
3713 are caught and silenced.

3729
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003730- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3731
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003732- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3733 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3734 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3735 ``printf`` function, whereas PyString_FromFormat has an independent
3736 implementation and uses "%zd" on all platforms for size_t values.
3737 This makes a difference on win64, where ``printf`` needs "%Id" to display
3738 64bit values.
3739
Benjamin Peterson97179b02008-09-09 20:55:01 +00003740- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3741 error.
3742
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003743- Issue #3777: long() applied to a float object now always return a long
3744 object; previously an int would be returned for small values. the __long__
3745 method is allowed to return either an int or a long, but the behaviour of
3746 float objects should not change to respect backward compatibility.
3747
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003748- Issue #3751: str.rpartition would perform a left-partition when called with
3749 a unicode argument.
3750
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003751- Issue #3683: Fix compilation when --without-threads is given.
3752
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003753- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003754 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003755 was correctly parsed but parsing of subsequent arguments failed.
3756
Vinay Sajip35e3b032008-09-01 14:33:59 +00003757- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003758 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3759 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3760 when given a tuple of classes as second argument, were looking up
3761 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3762 type object.
3763
Neal Norwitz18aa3882008-08-24 05:04:52 +00003764- Fix crashes on memory allocation failure found with failmalloc.
3765
3766- Fix memory leaks found with valgrind and update suppressions file.
3767
3768- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3769
3770- Fix problem using wrong name in decimal module reported by pychecker.
3771
Christian Heimes7d4c3172008-08-22 19:47:25 +00003772- Silenced another compiler warning about a used but not defined
3773 function 'stringlib_contains_obj'.
3774
Benjamin Peterson712ee922008-08-24 18:10:20 +00003775- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3776 ``__delslice__``.
3777
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003778- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3779 library targets in the Makefile.
3780
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003781- Issue #1204: The configure script now tests for additional libraries
3782 that may be required when linking against readline. This fixes issues
3783 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00003806- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003807 return a list or None rather than a custom object.
3808
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003809- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3810
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003811- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Georg Brandl222e2082010-08-01 22:27:39 +00003832- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00003833 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3834 for catch_warnings() also led to an improvement in the raising of a
3835 DeprecationWarning related to warnings.warn_explicit().
3836
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003837- The deprecation warnings for the old camelCase threading API were removed.

3859
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003860- Issue #2975: When compiling several extension modules with Visual Studio 2008
3861 from the same python interpreter, some environment variables would grow
3862 without limit.
3863
Benjamin Peterson37346b22008-08-23 20:27:43 +00003864- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3865 exploitation of poor argument checking.

3880 wrapper for warnings.catch_warnings() that makes it easier to check
3881 that expected warning messages are being reported.
3882

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003901What's New in Python 2.6 beta 3?

3906Core and Builtins
3907-----------------
3908
Guido van Rossumf8402962008-08-20 15:01:50 +00003909- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3910 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3911 extensions do not automatically benefit from the class attribute
3912 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3913 to their tp_flags field if they care. This is a backwards
3914 compatibility feature; in 3.0, all types will use the cache by
3915 default.
3916
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003917- Keyword arguments can now follow starred arguments. (``f(a, *args,
3918 keyword=23)`` is now valid syntax.)
3919
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003920- ctypes function pointers that are COM methods have a boolean True
3921 value again.
3922
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003923- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3924 by denying s# to parse objects that have a releasebuffer procedure,
3925 and introducing s*.
3926
Georg Brandl1e13ea92008-08-11 09:07:59 +00003927- Issue #3537: Fix an assertion failure when an empty but presized dict
3928 object was stored in the freelist.
3929
Mark Dickinsonb6467572008-08-04 21:30:09 +00003930- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3931 ValueError consistently across platforms.
3932
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003933- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3934 (64bit Unix, for example), unichr() would truncate its argument and return
3935 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3936
Neal Norwitze7d8be82008-07-31 17:17:14 +00003937- Apply security patches from Apple.
3938
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003939- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3940 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3941
Antoine Pitrou92f82162008-07-25 22:22:08 +00003942- Issue #1819: function calls with several named parameters are now on
3943 average 35% faster (as measured by pybench).
3944
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003945- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3946 the python debugger steps into a class statement: the free variables (local
3947 variables defined in an outer scope) would be deleted from the outer scope.
3948
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003949- Issue #2620: Overflow checking when allocating or reallocating memory
3950 was not always being done properly in some python types and extension
3951 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3952 all been updated to perform better checks and places in the code that
3953 would previously leak memory on the error path when such an allocation
3954 failed have been fixed.

3958
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003959- Issue #3612: Added some missing basic types in ctypes.wintypes.
3960
Benjamin Petersone977ad42008-08-20 01:42:01 +00003961- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3962 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3963
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003964- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3965 version reported by these tools does not necessarily follow the python
3966 version numbering scheme, so the module is less strict when parsing it.
3967
Nick Coghlanf70385a2008-08-18 12:42:46 +00003968- Issue #2235: Added Py3k warnings for types which will become unhashable
3969 under the stricter __hash__ inheritance rules in 3.0. Several types
3970 which did not meet the rules for hash invariants and were already
3971 unhashable in 3.0 have now been explicitly flagged as unhashable in
3972 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3973 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3974
Brett Cannon88f801d2008-08-18 00:46:22 +00003975- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3976 imported into the module but exposed as part of the module's API.
3977
Brett Cannon7b96f072008-08-18 00:41:11 +00003978- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3979

4088
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004089- Issue #643841: The language reference now provides more detailed

4101-----------------
4102
Georg Brandl3e483f62008-07-16 22:57:41 +00004103- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4104 its methods now allow for items objects that can be converted to
4105 an integer using operator.index().
4106
Mark Dickinson64b7e502008-07-16 09:40:03 +00004107- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4108 produced a ValueError instead of giving the correct float.
4109
Eric Smitha5fa5a22008-07-16 00:11:49 +00004110- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4111 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4112
Mark Dickinson7103aa42008-07-15 19:08:33 +00004113- Issue #3008: the float type has a new instance method 'float.hex'
4114 and a new class method 'float.fromhex' to convert floating-point
4115 numbers to and from hexadecimal strings, respectively.
4116
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004117- Issue #2235: __hash__ is once again inherited by default. To allow
4118 collections.Hashable to remain meaningful in the presence of the
4119 default hash implementation (object.__hash__), it is now possible
4120 to explicit block inheritance of hash by setting __hash__=None at
4121 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4122 level.
4123
Nick Coghlanb028f502008-07-13 14:52:36 +00004124- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4125 the parent module cannot be found while performing an absolute import.
4126 This means that an incorrectly defined __package__ attribute will
4127 now only prevent relative imports in that module rather than causing
4128 all imports from that module to fail.
4129
Nick Coghlan14ff9942008-07-08 14:21:42 +00004130- Issue #2517: Allow unicode messages in Exceptions again by correctly
4131 bypassing the instance dictionary when looking up __unicode__ on
4132 new-style classes.

4135 set to a custom object whose write() method happens to install
4136 another file in sys.stdout.
4137
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004138- Issue #3088: Corrected a race condition in classes derived from
4139 threading.local: the first member set by a thread could be saved in
4140 another thread's dictionary.
4141
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004142- Issue #3004: Minor change to slice.indices(): the start and stop
4143 arguments are now treated identically, making the behaviour easier
4144 to describe and understand. For example, slice(None, -10,
4145 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4146 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4147 10, -1).
4148
Georg Brandl278fc502008-07-19 12:46:12 +00004149- Issue #3219: Calling a function with repeated keyword arguments,
4150 f(a=2, a=23), would not cause a syntax error. This was a regression
4151 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004152
Georg Brandl278fc502008-07-19 12:46:12 +00004153- Issue #2862: Make int and float freelist management consistent with
4154 other freelists. Changes their CompactFreeList apis into

4161 api functions without holding the GIL, which could lead to a fatal
4162 error when they failed.
4163
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004164- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004189- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4190 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004191 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004192 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004208- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004599- On MacOS X it is now possible to install the framework in 64-bit
4600 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004601 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004602
4603 This is controlled by the configure argument ``--with-universal-archs``:
4604
4605 - ``--with-universal-archs=all``: install 4-way universal
4606
4607 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4608
4609 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4610
4611 This option should be used in combination with ``--enable-universalsdk=``.
4612
4613 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 +00004663- Issue #1631171: Re-implement the 'warnings' module in C (the
4664 original Python code has been kept as backup). This will allow for
4665 using the 'warning's machinery in such places as the parser where
4666 use of pure Python code is not possible. Both the ``showarning()``
4667 and ``formatwarning()`` gain an optional 'line' argument which is
4668 not called by default for backwards-compatibility reasons. Setting
4669 ``warnings.showwarning()`` to an implementation that lacks support
4670 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004733- Issue #2550: The approach used by client/server code for obtaining
4734 ports to listen on in network-oriented tests has been refined in an
4735 effort to facilitate running multiple instances of the entire
4736 regression test suite in parallel without issue.
4737 test_support.bind_port() has been fixed such that it will always
4738 return a unique port -- which wasn't always the case with the
4739 previous implementation, especially if socket options had been set
4740 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4741 new implementation of bind_port() will actually raise an exception
4742 if it is passed an AF_INET/SOCK_STREAM socket with either the
4743 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4744 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4745 the socket it's been passed. This currently only applies to
4746 Windows. This option prevents any other sockets from binding to the
4747 host/port we've bound to, thus removing the possibility of the
4748 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4749 when a second SOCK_STREAM socket binds and accepts to a host/port
4750 that's already been bound by another socket. The optional preferred
4751 port parameter to bind_port() has been removed. Under no
4752 circumstances should tests be hard coding ports!
4753
4754 test_support.find_unused_port() has also been introduced, which will
4755 pass a temporary socket object to bind_port() in order to obtain an
4756 unused port. The temporary socket object is then closed and
4757 deleted, and the port is returned. This method should only be used
4758 for obtaining an unused port in order to pass to an external program
4759 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4760 a parameter to a server-oriented class that doesn't give you direct
4761 access to the underlying socket used.
4762
4763 Finally, test_support.HOST has been introduced, which should be used
4764 for the host argument of any relevant socket calls (i.e. bind and
4765 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004766
4767 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004768 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004769 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4770 test_asynchat and test_socket_ssl.
4771
Georg Brandl3ee81df2008-05-17 18:14:43 +00004772 It is now possible for multiple instances of the regression test
4773 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00004827- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00004828 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4829 Plane. This affected raw unicode literals and the
4830 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4831 this case, like normal unicode literals and the 'unicode-escape'
4832 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005052- Added the future_builtins module, which contains hex() and oct().
5053 These are the PEP 3127 version of these functions, designed to be
5054 compatible with the hex() and oct() builtins from Python 3.0. They
5055 differ slightly in their output formats from the existing, unchanged
5056 Python 2.6 builtins. The expected usage of the future_builtins
5057 module is:
5058 from future_builtins import hex, oct
5059
Eric Smith7ef40bf2008-02-20 23:34:22 +00005060- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5061 exponents for exponents with absolute value < 100. Follows C99
5062 standard. This is a change on Windows, which would use 3 digits.
5063 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5064 so that any alterations it does to the resulting string will be

5066
Eric Smith5a3c1352008-02-19 13:21:56 +00005067- Implemented PEP 3101, Advanced String Formatting. This adds a new
5068 builtin format(); a format() method for str and unicode; a
5069 __format__() method to object, str, unicode, int, long, float, and
5070 datetime; the class string.Formatter; and the C API
5071 PyObject_Format().
5072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Fixed several potential crashes, all caused by specially crafted
5074 __del__ methods exploiting objects in temporarily inconsistent
5075 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005118- Patch #1473257: generator objects gain a gi_code attribute. This is
5119 the same object as the func_code attribute of the function that
5120 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005121
Georg Brandl3ee81df2008-05-17 18:14:43 +00005122- Issue #1920: "while 0" statements were completely removed by the
5123 compiler, even in the presence of an "else" clause, which is
5124 supposed to be run when the condition is false. Now the compiler
5125 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005126

Christian Heimes288e89a2008-01-18 18:24:07 +00005145 added.
5146
Christian Heimesc94e2b52008-01-14 04:13:37 +00005147- sys.float_info / PyFloat_GetInfo: The floating point information
5148 object was converted from a dict to a specialized structseq object.
5149
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150- Patch #1816: Added sys.flags structseq. It exposes the status of
5151 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Objects/structseq.c: Implemented new structseq representation. The
5154 patch makes structseqs (e.g. the return value of os.stat) more
5155 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005156
Georg Brandl3ee81df2008-05-17 18:14:43 +00005157- Patch #1700288: added a type attribute cache that caches method
5158 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005159

5166 envvar and sys.dont_write_bytecode attribute. All these can be set
5167 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005168
Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Improve some exception messages when Windows fails to load an
5170 extension module. Now we get for example '%1 is not a valid Win32
5171 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005230 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5231 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005232
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233- Issue #1686386: Tuple's tp_repr did not take into account the
5234 possibility of having a self-referential tuple, which is possible
5235 from C code. Nor did object's tp_str consider that a type's tp_str
5236 could do something that could lead to an inifinite recursion.
5237 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5238 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005239

5241 'print' statement to write to a file since the GIL was not released
5242 as needed. Now PyObject_Print() does the right thing along with
5243 various tp_print implementations of the built-in types and those in
5244 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005245

Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 PyObject_Call() never calling back out to Python code to trigger
5255 recursion depth updates/checks. Required the creation of a static
5256 RuntimeError instance in case normalizing an exception put the
5257 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00005306- Bug #1683368: The object.__init__() and object.__new__() methods are
5307 now stricter in rejecting excess arguments. The only time when
5308 either allows excess arguments is when it is not overridden and the
5309 other one is. For backwards compatibility, when both are
5310 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005311 warning later). Also, type.__init__() insists on the same signature
5312 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005314- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5315 object to complex using its __complex__() method before falling back
5316 to the __float__() method. Therefore, the functions in the cmath
5317 module now can operate on objects that define a __complex__()
5318 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005336- Bug #1678647: write a newline after printing an exception in any
5337 case, even when converting the value to a string failed.
5338
Georg Brandl871f1bc2007-03-12 13:17:36 +00005339- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005340 its argument, if it exists. If not, it will work like before. This
5341 allows customizing the output of dir() in the presence of a
5342 __getattr__().

5352 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005354- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355 makes the filenames the warning module prints much more sensible
5356 when a PYTHONSTARTUP file is used.

5371
Georg Brandl3ee81df2008-05-17 18:14:43 +00005372- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00005424- Bug #1545497: when given an explicit base, int() did ignore NULs
5425 embedded in the string to convert.
5426
Georg Brandl846f73a2006-10-08 07:11:54 +00005427- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005475 generator expressions (x for x, in ... ) works again. Fixing this
5476 problem required changing the .pyc magic number. This means that

6278 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00006279
Georg Brandl3ee81df2008-05-17 18:14:43 +00006280- The implementation of UnicodeError objects has been simplified
6281 (start and end attributes are now stored directly as Py_ssize_t
6282 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00006283
Georg Brandl3ee81df2008-05-17 18:14:43 +00006284- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6285 with RFC 3207 and forgets any knowledge obtained from the server not
6286 obtained from the TLS negotiation itself. Patch contributed by Bill
6287 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006290 that the SMTP.starttls() caller no longer needs to call ehlo()
6291 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006292 does not claim to support starttls. Adds the
6293 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6294 Fenner.

6363 contents before adding elements from the iterable. This fix brings
6364 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00006365
Georg Brandl3ee81df2008-05-17 18:14:43 +00006366- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00006373- Marshal.dumps() now expects exact type matches for int, long, float,
6374 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6375 silently miscode subclasses of those types. Now, it raises a
6376 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006377

Georg Brandl3ee81df2008-05-17 18:14:43 +00006392 time so that opening a database previously created with the DB_DUP
6393 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6394 opens. Specifically: dictionary assignment to a DB object will
6395 replace all values for a given key when the database allows
6396 duplicate values. DB users should use DB.put(k, v) when they want
6397 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006398

6404 characters with ASCII value less than 32. Also, it correctly quotes
6405 dots only if they occur on a single line, as opposed to the previous
6406 behavior of quoting dots if they are the second character of any
6407 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006408

Georg Brandl3ee81df2008-05-17 18:14:43 +00006813- Removed the macfs module. It had been deprecated since Python 2.5.
6814 This lead to the deprecation of macostools.touched() as it relied
6815 solely on macfs and was a no-op under OS X.
