246 This prevents user-created self-referencing ordered dictionaries from
247 becoming permanently uncollectable GC garbage. The downside is that
248 removing __del__ means that the internal doubly-linked list has to wait for
249 GC collection rather than freeing memory immediately when the refcnt drops
250 to zero.

259 original error is re-raised.
260
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000261- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

263 be updated back after the system call. Original patch by Brian Brazil.
264
Antoine Pitroudca9de92010-09-04 17:52:26 +0000265- Issue #1100562: Fix deep-copying of objects derived from the list and
266 dict types. Patch by Michele Orrù and Björn Lindqvist.

269 ConfigParser.write.
270
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000271- Issue #808164: Fixed socket.close to avoid references to globals, to
272 avoid issues when socket.close is called from a __del__ method.
273
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000274- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

276 heuristic. Patch by Terry Reedy and Eli Bendersky

279 falling into recursion.
280
R. David Murray7c4bf552010-08-25 01:45:57 +0000281- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
282 character years even if the message contains RFC822 two character years.
283
Daniel Stutzbach91287322010-08-24 21:09:30 +0000284- Issue #8750: Fixed MutableSet's methods to correctly handle
285 reflexive operations, namely x -= x and x ^= x.
286

303
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000304- Issue #9626: the view methods for collections.OrderedDict() were returning

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000708- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
709 start byte and the continuation byte(s) are now considered invalid, instead
710 of the number of bytes specified by the start byte.
711 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
712 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
713 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

723 objects. (1) The comparison could incorrectly return True in some cases
724 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1110 with a non-empty format string. This is an effort to future-proof user
1111 code. If a derived class does not currently implement __format__ but later
1112 adds its own __format__, it would most likely break user code that had
1113 supplied a format string. This will be changed to a DeprecationWaring in

Georg Brandlfee0f442010-05-22 21:26:21 +00001147- Issue #8257: The Decimal construct now accepts a float instance directly,
1148 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001149
1150 >>> Decimal(1.1)
1151 Decimal('1.100000000000000088817841970012523233890533447265625')
1152

Georg Brandlfee0f442010-05-22 21:26:21 +00001164- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1165 InvalidOperation instead of returning False. (Comparisons involving a quiet
1166 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1167 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001168
Georg Brandlfee0f442010-05-22 21:26:21 +00001169- Issue #2531: Comparison operations between floats and Decimal instances now
1170 return a result based on the numeric values of the operands; previously they
1171 returned an arbitrary result based on the relative ordering of id(float) and
1172 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001173
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001174- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001175 argument `-` which tells it to read files to compile from stdin. Each line is
1176 read on demand and the named file is compiled immediately. (Original patch by
1177 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001186- Comparisons using one of <, <=, >, >= between a complex instance and a
1187 Fractions instance now raise TypeError instead of returning True/False. This
1188 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1189 <=> complex, and complex <=> complex comparisons.

1258 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1259 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001288- Issue #8300: When passing a non-integer argument to struct.pack with any
1289 integer format code, struct.pack first attempts to convert the non-integer

1291 TypeError it goes on to try the __int__ method, as described below.
1292
Georg Brandlba83f822010-03-14 09:50:54 +00001293- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1294 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1295 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001296 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1297 inconsistent: __int__ was used for some integer codes but not for others, and
1298 the set of integer codes for which it was used differed between native packing
1299 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001603 file position when calling `truncate()`. It would previously change the file
1604 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001605 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00001607- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1608 class used to represent files stored inside an archive. The new
1609 implementation is significantly faster and can be wrapped in a
1610 ``io.BufferedReader`` object for more speedups. It also solves an issue
1611 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1624 encoded string for them. This ensures that the upload and register commands
1625 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001702- The ``__complex__()`` method is now looked up on the class of instances to
1703 make it consistent with other special methods.

1707
Mark Dickinson1b34d252010-01-01 17:27:30 +00001708- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001709 DeprecationWarning when passed a float argument where an integer was expected.
1710 These functions and methods now raise TypeError instead. The majority of the
1711 effects of this change are in the extension modules, but some core functions
1712 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1713 and many unicode/str methods.

1727 of integers: the result of a/b is now correctly rounded for ints a and b (at
1728 least on IEEE 754 platforms), and in particular does not depend on the
1729 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001878- Issue #3382: 'F' formatting for float and complex now convert the result to
1879 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1880 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001881
Georg Brandlba83f822010-03-14 09:50:54 +00001882- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1883 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001884
Georg Brandlba83f822010-03-14 09:50:54 +00001885- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1886 1e-100 used to raise OverflowError, but now gives the requested 120
1887 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001888

1894 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001895
Georg Brandlba83f822010-03-14 09:50:54 +00001896- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1897 decimal string that's guaranteed to round back to x under correct rounding
1898 (with round-half-to-even rounding mode). Previously it gave a string based on
1899 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1900 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1901 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001902
Georg Brandlba83f822010-03-14 09:50:54 +00001903- Issue #7117: On almost all platforms: float-to-string and string-to-float
1904 conversions within Python are now correctly rounded. Places these conversions
1905 occur include: str for floats and complex numbers; the float and complex
1906 constructors; old-style and new-style numeric formatting; serialization and
1907 deserialization of floats and complex numbers using marshal, pickle and json;
1908 parsing of float and imaginary literals in Python code; Decimal-to-float
1909 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001910
Georg Brandlba83f822010-03-14 09:50:54 +00001911 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1912 providing correctly-rounded strtod and dtoa C functions. This code is
1913 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1914 the C compiler. There may be a small number of platforms on which correct
1915 operation of this code cannot be guaranteed, so the code is not used: notably,
1916 this applies to platforms where the C double format is not IEEE 754 binary64,
1917 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1918 and Python's configure script is unable to determine how to change the FPU
1919 precision. On these platforms conversions use the platform strtod and dtoa,
1920 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001921
Georg Brandlba83f822010-03-14 09:50:54 +00001922- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1923 uses the correctly-rounded string <-> float conversions described above (when
1924 available), and so produces correctly rounded results that will display nicely
1925 under the float repr. There are two related small changes: (1) round now
1926 accepts any class with an ``__index__()`` method for its second argument (but
1927 no longer accepts floats for the second argument), and (2) an excessively
1928 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1929 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002076- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2077 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2078 but with at least one decimal point and with a default precision
2079 of 12. Previously, the behavior the same but with a default precision of 6.
2080 This more closely matches ``str()``, and reduces surprises when adding
2081 alignment flags to the empty presentation type. This also affects the new
2082 complex.__format__ in the same way.
2083
2084- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2085 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00002306- On windows, ``os.chdir()`` given unicode was not working if
2307 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2308 this code path is really executed because I cannot move to such directory on
2309 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002311- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2312 element is temporarily replaced with an equivalent frozenset. But the
2313 eventual KeyError would always report the empty ``frozenset()`` as the missing
2314 key. Now it correctly refers to the initial element.

3692 exactly the recursion limit is exceeded. Consequently, both exception types
3693 are caught and silenced.

3709
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003710- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3711
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003712- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3713 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3714 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3715 ``printf`` function, whereas PyString_FromFormat has an independent
3716 implementation and uses "%zd" on all platforms for size_t values.
3717 This makes a difference on win64, where ``printf`` needs "%Id" to display
3718 64bit values.
3719
Benjamin Peterson97179b02008-09-09 20:55:01 +00003720- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3721 error.
3722
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003723- Issue #3777: long() applied to a float object now always return a long
3724 object; previously an int would be returned for small values. the __long__
3725 method is allowed to return either an int or a long, but the behaviour of
3726 float objects should not change to respect backward compatibility.
3727
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003728- Issue #3751: str.rpartition would perform a left-partition when called with
3729 a unicode argument.
3730
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003731- Issue #3683: Fix compilation when --without-threads is given.
3732
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003733- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003734 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003735 was correctly parsed but parsing of subsequent arguments failed.
3736
Vinay Sajip35e3b032008-09-01 14:33:59 +00003737- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003738 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3739 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3740 when given a tuple of classes as second argument, were looking up
3741 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3742 type object.
3743
Neal Norwitz18aa3882008-08-24 05:04:52 +00003744- Fix crashes on memory allocation failure found with failmalloc.
3745
3746- Fix memory leaks found with valgrind and update suppressions file.
3747
3748- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3749
3750- Fix problem using wrong name in decimal module reported by pychecker.
3751
Christian Heimes7d4c3172008-08-22 19:47:25 +00003752- Silenced another compiler warning about a used but not defined
3753 function 'stringlib_contains_obj'.
3754
Benjamin Peterson712ee922008-08-24 18:10:20 +00003755- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3756 ``__delslice__``.
3757
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003758- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3759 library targets in the Makefile.
3760
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003761- Issue #1204: The configure script now tests for additional libraries
3762 that may be required when linking against readline. This fixes issues
3763 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00003787 return a list or None rather than a custom object.
3788
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003789- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003813 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3814 for catch_warnings() also led to an improvement in the raising of a
3815 DeprecationWarning related to warnings.warn_explicit().
3816
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003817- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003840- Issue #2975: When compiling several extension modules with Visual Studio 2008
3841 from the same python interpreter, some environment variables would grow
3842 without limit.
3843
Benjamin Peterson37346b22008-08-23 20:27:43 +00003844- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003881What's New in Python 2.6 beta 3?
3882================================
3883
Barry Warsaw07a4a382008-08-21 01:15:08 +00003884*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003885
3886Core and Builtins
3887-----------------
3888
Guido van Rossumf8402962008-08-20 15:01:50 +00003889- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3890 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3891 extensions do not automatically benefit from the class attribute
3892 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3893 to their tp_flags field if they care. This is a backwards
3894 compatibility feature; in 3.0, all types will use the cache by
3895 default.
3896
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003897- Keyword arguments can now follow starred arguments. (``f(a, *args,
3898 keyword=23)`` is now valid syntax.)
3899
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003900- ctypes function pointers that are COM methods have a boolean True
3901 value again.
3902
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003903- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3904 by denying s# to parse objects that have a releasebuffer procedure,
3905 and introducing s*.
3906
Georg Brandl1e13ea92008-08-11 09:07:59 +00003907- Issue #3537: Fix an assertion failure when an empty but presized dict
3908 object was stored in the freelist.
3909
Mark Dickinsonb6467572008-08-04 21:30:09 +00003910- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3911 ValueError consistently across platforms.
3912
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003913- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3914 (64bit Unix, for example), unichr() would truncate its argument and return
3915 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3916
Neal Norwitze7d8be82008-07-31 17:17:14 +00003917- Apply security patches from Apple.
3918
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003919- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3920 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3921
Antoine Pitrou92f82162008-07-25 22:22:08 +00003922- Issue #1819: function calls with several named parameters are now on
3923 average 35% faster (as measured by pybench).
3924
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003925- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3926 the python debugger steps into a class statement: the free variables (local
3927 variables defined in an outer scope) would be deleted from the outer scope.
3928
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003929- Issue #2620: Overflow checking when allocating or reallocating memory
3930 was not always being done properly in some python types and extension
3931 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3932 all been updated to perform better checks and places in the code that
3933 would previously leak memory on the error path when such an allocation
3934 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00003941- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3942 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3943
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003944- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3945 version reported by these tools does not necessarily follow the python
3946 version numbering scheme, so the module is less strict when parsing it.
3947
Nick Coghlanf70385a2008-08-18 12:42:46 +00003948- Issue #2235: Added Py3k warnings for types which will become unhashable
3949 under the stricter __hash__ inheritance rules in 3.0. Several types
3950 which did not meet the rules for hash invariants and were already
3951 unhashable in 3.0 have now been explicitly flagged as unhashable in
3952 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3953 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3954
Brett Cannon88f801d2008-08-18 00:46:22 +00003955- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3956 imported into the module but exposed as part of the module's API.
3957

3963
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003964- Issue #3575: Incremental decoder's decode function now takes bytearray
3965 by using 's*' instead of 't#'.
3966
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003967- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003968 fails unicode conversion on 2nd parameter. (windows only)
3969
Georg Brandl222e2082010-08-01 22:27:39 +00003970- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003971 in a redirect.
3972

Antoine Pitroude781a42008-08-09 12:43:23 +00004024 asking for a specific length. This problem only affected files opened
4025 using the new "io" module, not the built-in open() function.

4051 file name rather than a ZipInfo instance, so files are extracted with
4052 mode 0600 rather than 000 under Unix.
4053
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004054- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4067 interaction with the tp_hash slot (added in 2.6b2) are now documented
4068
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004069- Issue #643841: The language reference now provides more detailed

4081-----------------
4082
Georg Brandl3e483f62008-07-16 22:57:41 +00004083- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4084 its methods now allow for items objects that can be converted to
4085 an integer using operator.index().
4086
Mark Dickinson64b7e502008-07-16 09:40:03 +00004087- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4088 produced a ValueError instead of giving the correct float.
4089
Eric Smitha5fa5a22008-07-16 00:11:49 +00004090- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4091 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4092
Mark Dickinson7103aa42008-07-15 19:08:33 +00004093- Issue #3008: the float type has a new instance method 'float.hex'
4094 and a new class method 'float.fromhex' to convert floating-point
4095 numbers to and from hexadecimal strings, respectively.
4096
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004097- Issue #2235: __hash__ is once again inherited by default. To allow
4098 collections.Hashable to remain meaningful in the presence of the
4099 default hash implementation (object.__hash__), it is now possible
4100 to explicit block inheritance of hash by setting __hash__=None at
4101 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4102 level.
4103
Nick Coghlanb028f502008-07-13 14:52:36 +00004104- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4105 the parent module cannot be found while performing an absolute import.
4106 This means that an incorrectly defined __package__ attribute will
4107 now only prevent relative imports in that module rather than causing
4108 all imports from that module to fail.
4109
Nick Coghlan14ff9942008-07-08 14:21:42 +00004110- Issue #2517: Allow unicode messages in Exceptions again by correctly

4120 another thread's dictionary.
4121
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004122- Issue #3004: Minor change to slice.indices(): the start and stop
4123 arguments are now treated identically, making the behaviour easier
4124 to describe and understand. For example, slice(None, -10,
4125 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4126 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4127 10, -1).
4128
Georg Brandl278fc502008-07-19 12:46:12 +00004129- Issue #3219: Calling a function with repeated keyword arguments,
4130 f(a=2, a=23), would not cause a syntax error. This was a regression
4131 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004133- Issue #2862: Make int and float freelist management consistent with
4134 other freelists. Changes their CompactFreeList apis into

4141 api functions without holding the GIL, which could lead to a fatal
4142 error when they failed.
4143
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004144- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004169- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4170 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004171 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004172 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004188- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4578
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004579- On MacOS X it is now possible to install the framework in 64-bit
4580 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004581 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004582
4583 This is controlled by the configure argument ``--with-universal-archs``:
4584
4585 - ``--with-universal-archs=all``: install 4-way universal
4586
4587 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4588
4589 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4590
4591 This option should be used in combination with ``--enable-universalsdk=``.
4592
4593 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 +00004643- Issue #1631171: Re-implement the 'warnings' module in C (the
4644 original Python code has been kept as backup). This will allow for
4645 using the 'warning's machinery in such places as the parser where
4646 use of pure Python code is not possible. Both the ``showarning()``
4647 and ``formatwarning()`` gain an optional 'line' argument which is
4648 not called by default for backwards-compatibility reasons. Setting
4649 ``warnings.showwarning()`` to an implementation that lacks support
4650 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004675- The getpass module has been improved on Unix. It now uses /dev/tty
4676 by default and uses stderr instead of stdout. A GetPassWarning is
4677 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004692- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004693 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Issue #2550: The approach used by client/server code for obtaining
4714 ports to listen on in network-oriented tests has been refined in an
4715 effort to facilitate running multiple instances of the entire
4716 regression test suite in parallel without issue.
4717 test_support.bind_port() has been fixed such that it will always
4718 return a unique port -- which wasn't always the case with the
4719 previous implementation, especially if socket options had been set
4720 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4721 new implementation of bind_port() will actually raise an exception
4722 if it is passed an AF_INET/SOCK_STREAM socket with either the
4723 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4724 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4725 the socket it's been passed. This currently only applies to
4726 Windows. This option prevents any other sockets from binding to the
4727 host/port we've bound to, thus removing the possibility of the
4728 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4729 when a second SOCK_STREAM socket binds and accepts to a host/port
4730 that's already been bound by another socket. The optional preferred
4731 port parameter to bind_port() has been removed. Under no
4732 circumstances should tests be hard coding ports!
4733
4734 test_support.find_unused_port() has also been introduced, which will
4735 pass a temporary socket object to bind_port() in order to obtain an
4736 unused port. The temporary socket object is then closed and
4737 deleted, and the port is returned. This method should only be used
4738 for obtaining an unused port in order to pass to an external program
4739 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4740 a parameter to a server-oriented class that doesn't give you direct
4741 access to the underlying socket used.
4742
4743 Finally, test_support.HOST has been introduced, which should be used
4744 for the host argument of any relevant socket calls (i.e. bind and
4745 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004746
4747 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004748 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004749 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4750 test_asynchat and test_socket_ssl.
4751
Georg Brandl3ee81df2008-05-17 18:14:43 +00004752 It is now possible for multiple instances of the regression test
4753 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005032- Added the future_builtins module, which contains hex() and oct().
5033 These are the PEP 3127 version of these functions, designed to be
5034 compatible with the hex() and oct() builtins from Python 3.0. They
5035 differ slightly in their output formats from the existing, unchanged
5036 Python 2.6 builtins. The expected usage of the future_builtins
5037 module is:
5038 from future_builtins import hex, oct
5039
Eric Smith7ef40bf2008-02-20 23:34:22 +00005040- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5041 exponents for exponents with absolute value < 100. Follows C99
5042 standard. This is a change on Windows, which would use 3 digits.
5043 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5044 so that any alterations it does to the resulting string will be
5045 available in stringlib/formatter.h (for float.__format__).
5046
Eric Smith5a3c1352008-02-19 13:21:56 +00005047- Implemented PEP 3101, Advanced String Formatting. This adds a new
5048 builtin format(); a format() method for str and unicode; a
5049 __format__() method to object, str, unicode, int, long, float, and
5050 datetime; the class string.Formatter; and the C API
5051 PyObject_Format().
5052
Georg Brandl3ee81df2008-05-17 18:14:43 +00005053- Fixed several potential crashes, all caused by specially crafted
5054 __del__ methods exploiting objects in temporarily inconsistent
5055 state.

5059 a slot on a registered virtual subclass.

5062 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005063
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064- Clear all free lists during a gc.collect() of the highest generation
5065 in order to allow pymalloc to free more arenas. Python may give back
5066 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005067
Georg Brandl3ee81df2008-05-17 18:14:43 +00005068- Issue #2045: Fix an infinite recursion triggered when printing a
5069 subclass of collections.defaultdict, if its default_factory is set
5070 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005071
Christian Heimesf75dbef2008-02-08 00:11:31 +00005072- Fixed a minor memory leak in dictobject.c. The content of the free
5073 list was not freed on interpreter shutdown.
5074
Georg Brandl21e99f42010-03-07 15:23:59 +00005075- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005076 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005077
Georg Brandl3ee81df2008-05-17 18:14:43 +00005078- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5079 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005080 to compact the internal free lists of pre-allocted ints and floats.
5081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5083 calls. Python expected the return type int but the fork familie
5084 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005085
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5087 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005088
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5090 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005091
Georg Brandl3ee81df2008-05-17 18:14:43 +00005092- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005095- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5096 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005097
Georg Brandl3ee81df2008-05-17 18:14:43 +00005098- Patch #1473257: generator objects gain a gi_code attribute. This is
5099 the same object as the func_code attribute of the function that
5100 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005101
Georg Brandl3ee81df2008-05-17 18:14:43 +00005102- Issue #1920: "while 0" statements were completely removed by the
5103 compiler, even in the presence of an "else" clause, which is
5104 supposed to be run when the condition is false. Now the compiler
5105 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005106
Guido van Rossumeead05f2008-01-24 18:21:02 +00005107- A few crashers fixed: weakref_in_del.py (issue #1377858);
5108 loosing_dict_ref.py (issue #1303614, test67.py);
5109 borrowed_ref_[34].py (not in tracker).
5110
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005111- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005112 suppressed while an extension is loaded by calling SetErrorMode in
5113 dynload_win.c. The error is still reported properly.
5114
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005116 several extension methods and modules do not work without unicode
5117 support.
5118
Georg Brandl26543b12008-01-21 18:36:51 +00005119- Issue #1882: when compiling code from a string, encoding cookies in the
5120 second line of code were not always recognized correctly.
5121
Georg Brandl14404b62008-01-19 19:27:05 +00005122- Issue #1679: "0x" was taken as a valid integer literal.
5123
Georg Brandl6caad7d2008-01-26 14:19:22 +00005124- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005125 added.
5126
Christian Heimesc94e2b52008-01-14 04:13:37 +00005127- sys.float_info / PyFloat_GetInfo: The floating point information
5128 object was converted from a dict to a specialized structseq object.
5129
Georg Brandl3ee81df2008-05-17 18:14:43 +00005130- Patch #1816: Added sys.flags structseq. It exposes the status of
5131 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005132
Georg Brandl3ee81df2008-05-17 18:14:43 +00005133- Objects/structseq.c: Implemented new structseq representation. The
5134 patch makes structseqs (e.g. the return value of os.stat) more
5135 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- Patch #1700288: added a type attribute cache that caches method
5138 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005139
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005140- Bug #1776: __import__() no longer accepts filenames on any platform.
5141 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005142
Georg Brandlaed6c662008-01-07 17:25:53 +00005143- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5146 envvar and sys.dont_write_bytecode attribute. All these can be set
5147 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Improve some exception messages when Windows fails to load an
5150 extension module. Now we get for example '%1 is not a valid Win32
5151 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005152

5156 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005157
Christian Heimes0a8143f2007-12-18 23:22:54 +00005158- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159 and INF. float("nan"), float("inf") and float("-inf") now work on
5160 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005161
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- Compiler now generates simpler and faster code for dictionary
5163 literals. The oparg for BUILD_MAP now indicates an estimated
5164 dictionary size. There is a new opcode, STORE_MAP, for adding
5165 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- Patch #1739468: Directories and zipfiles containing a __main__.py
5195 file can now be directly executed by passing their name to the
5196 interpreter. The directory/zipfile is automatically inserted as the
5197 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005198
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199- Issue #1265: Fix a problem with sys.settrace, if the tracing
5200 function uses a generator expression when at the same time the
5201 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005202
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005203- sets and frozensets now have an isdisjoint() method.
5204
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005205- optimize the performance of builtin.sum().
5206
Neal Norwitz44f326e2007-10-05 05:29:17 +00005207- Fix warnings found by the new version of the Coverity checker.
5208
Georg Brandl21e99f42010-03-07 15:23:59 +00005209- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005210 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5211 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005212
Georg Brandl3ee81df2008-05-17 18:14:43 +00005213- Issue #1686386: Tuple's tp_repr did not take into account the
5214 possibility of having a self-referential tuple, which is possible
5215 from C code. Nor did object's tp_str consider that a type's tp_str
5216 could do something that could lead to an inifinite recursion.
5217 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5218 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005219
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220- Issue #1164: It was possible to trigger deadlock when using the
5221 'print' statement to write to a file since the GIL was not released
5222 as needed. Now PyObject_Print() does the right thing along with
5223 various tp_print implementations of the built-in types and those in
5224 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005225
Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Issue #1147: Exceptions were directly allowing string exceptions in
5227 their throw() method even though string exceptions no longer
5228 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005229
Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Issue #1096: Prevent a segfault from getting the repr of a very
5231 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005232
Brett Cannon1e534b52007-09-07 04:18:30 +00005233- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005234 PyObject_Call() never calling back out to Python code to trigger
5235 recursion depth updates/checks. Required the creation of a static
5236 RuntimeError instance in case normalizing an exception put the
5237 recursion check value past its limit. Fixes crashers
5238 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005239

Neal Norwitz0ac60192007-05-27 04:08:54 +00005253- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 __*__ attributes. (Some already existed, e.g., __doc__ and
5255 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005256
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005257- Add -3 option to the interpreter to warn about features that are
5258 deprecated and will be changed/removed in Python 3.0.
5259
Georg Brandl2134e752007-05-21 20:34:16 +00005260- Patch #1686487: you can now pass any mapping after '**' in function
5261 calls.
5262
Collin Winter62903052007-05-18 23:11:24 +00005263- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005264 "except E as target:". This is to provide forwards compatibility
5265 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00005267- Deprecate BaseException.message as per PEP 352.
5268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005270 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005272- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005273 setting a plain string, ie don't expand to single letter identifiers.
5274
Raymond Hettinger13936692007-04-11 18:40:58 +00005275- Request #1191699: Slices can now be pickled.
5276
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005277- Request #1193128: str.translate() now allows a None argument for
5278 translations that only remove characters without re-mapping the
5279 remaining characters.
5280
Georg Brandl5cb76c12007-03-21 09:00:39 +00005281- Patch #1682205: a TypeError while unpacking an iterable is no longer
5282 masked by a generic one with the message "unpack non-sequence".
5283
Neal Norwitzaa754b72007-03-21 06:39:48 +00005284- Remove unused file Python/fmod.c.
5285
Guido van Rossum143b5642007-03-23 04:58:42 +00005286- Bug #1683368: The object.__init__() and object.__new__() methods are
5287 now stricter in rejecting excess arguments. The only time when
5288 either allows excess arguments is when it is not overridden and the
5289 other one is. For backwards compatibility, when both are
5290 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005291 warning later). Also, type.__init__() insists on the same signature
5292 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005294- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5295 object to complex using its __complex__() method before falling back
5296 to the __float__() method. Therefore, the functions in the cmath
5297 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006270 that the SMTP.starttls() caller no longer needs to call ehlo()
6271 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272 does not claim to support starttls. Adds the
6273 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6274 Fenner.

6354 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6355 silently miscode subclasses of those types. Now, it raises a
6356 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006357

Georg Brandl3ee81df2008-05-17 18:14:43 +00006372 time so that opening a database previously created with the DB_DUP
6373 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6374 opens. Specifically: dictionary assignment to a DB object will
6375 replace all values for a given key when the database allows
6376 duplicate values. DB users should use DB.put(k, v) when they want
6377 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006378

6384 characters with ASCII value less than 32. Also, it correctly quotes
6385 dots only if they occur on a single line, as opposed to the previous
6386 behavior of quoting dots if they are the second character of any
6387 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006388
