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

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000233 value.
234
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000235- Issue #9792: In case of connection failure, socket.create_connection()
236 would swallow the exception and raise a new one, making it impossible
237 to fetch the original errno, or to filter timeout errors. Now the
238 original error is re-raised.
239
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000240- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
241 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
242 be updated back after the system call. Original patch by Brian Brazil.
243
Antoine Pitroudca9de92010-09-04 17:52:26 +0000244- Issue #1100562: Fix deep-copying of objects derived from the list and

248 ConfigParser.write.
249
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000250- Issue #808164: Fixed socket.close to avoid references to globals, to
251 avoid issues when socket.close is called from a __del__ method.
252
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000253- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

255 heuristic. Patch by Terry Reedy and Eli Bendersky

259
R. David Murray7c4bf552010-08-25 01:45:57 +0000260- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
261 character years even if the message contains RFC822 two character years.
262
Daniel Stutzbach91287322010-08-24 21:09:30 +0000263- Issue #8750: Fixed MutableSet's methods to correctly handle
264 reflexive operations, namely x -= x and x ^= x.
265
Victor Stinnercaafd772010-09-08 10:51:01 +0000266- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

278 ignored by the buffered IO layer anymore.
279
Benjamin Peterson52c36052010-08-21 03:03:22 +0000280- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
281 are not held onto after they are deleted elsewhere.
282
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000283- Issue #9626: the view methods for collections.OrderedDict() were returning
284 the unordered versions inherited from dict. Those methods are now
285 overridden to provide ordered views.

686
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000687- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
688 start byte and the continuation byte(s) are now considered invalid, instead
689 of the number of bytes specified by the start byte.
690 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
691 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
692 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
693 Previous versions returned a single u'\ufffd'.
694
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000695- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000696 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
697 arises from the "Overriding __eq__ blocks inheritance ..." warning
698 when turned into an exception: in this case the exception simply
699 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000701- Issue #8748: Fix two issues with comparisons between complex and integer
702 objects. (1) The comparison could incorrectly return True in some cases
703 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
704 (2) The comparison raised an OverflowError for large integers, leading
705 to unpredictable exceptions when combining integers and complex objects
706 in sets or dicts.
707
Mark Dickinson81336372010-05-30 12:12:25 +0000708- Issue #5211: Implicit coercion for the complex type is now completely
709 removed. (Coercion for arithmetic operations was already removed in 2.7
710 alpha 4, but coercion for rich comparisons was accidentally left in.)
711
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000712- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
713 and error handler, instead of writing to the C stderr file in utf-8
714
Georg Brandlfee0f442010-05-22 21:26:21 +0000715- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +0000899- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
900 operation raises multiple signals and more than one of those signals is
901 trapped, the specification determines the order in which the signals should be
902 handled. In many cases this order wasn't being followed, leading to the wrong
903 Python exception being raised.

1089 with a non-empty format string. This is an effort to future-proof user
1090 code. If a derived class does not currently implement __format__ but later
1091 adds its own __format__, it would most likely break user code that had
1092 supplied a format string. This will be changed to a DeprecationWaring in

Georg Brandlfee0f442010-05-22 21:26:21 +00001143- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1144 InvalidOperation instead of returning False. (Comparisons involving a quiet
1145 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1146 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001148- Issue #2531: Comparison operations between floats and Decimal instances now
1149 return a result based on the numeric values of the operands; previously they
1150 returned an arbitrary result based on the relative ordering of id(float) and
1151 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001153- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001154 argument `-` which tells it to read files to compile from stdin. Each line is
1155 read on demand and the named file is compiled immediately. (Original patch by
1156 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001165- Comparisons using one of <, <=, >, >= between a complex instance and a
1166 Fractions instance now raise TypeError instead of returning True/False. This
1167 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1168 <=> complex, and complex <=> complex comparisons.

1271
Georg Brandlba83f822010-03-14 09:50:54 +00001272- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1273 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001275 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1276 inconsistent: __int__ was used for some integer codes but not for others, and
1277 the set of integer codes for which it was used differed between native packing
1278 and standard packing.)

1583 position to the given argument, which goes against the tradition of

1603 encoded string for them. This ensures that the upload and register commands
1604 send the correct values to PyPI without any error.

1680
Georg Brandlba83f822010-03-14 09:50:54 +00001681- The ``__complex__()`` method is now looked up on the class of instances to
1682 make it consistent with other special methods.

1686
Mark Dickinson1b34d252010-01-01 17:27:30 +00001687- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001688 DeprecationWarning when passed a float argument where an integer was expected.
1689 These functions and methods now raise TypeError instead. The majority of the
1690 effects of this change are in the extension modules, but some core functions
1691 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1692 and many unicode/str methods.

1706 of integers: the result of a/b is now correctly rounded for ints a and b (at
1707 least on IEEE 754 platforms), and in particular does not depend on the
1708 internal representation of a long.

1716
Georg Brandlba83f822010-03-14 09:50:54 +00001717 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001854- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1855 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001856
Georg Brandlba83f822010-03-14 09:50:54 +00001857- Issue #3382: 'F' formatting for float and complex now convert the result to
1858 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1859 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001860
Georg Brandlba83f822010-03-14 09:50:54 +00001861- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1862 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001863
Georg Brandlba83f822010-03-14 09:50:54 +00001864- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1865 1e-100 used to raise OverflowError, but now gives the requested 120
1866 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001867
Georg Brandlba83f822010-03-14 09:50:54 +00001868- Add Py3k warnings for parameter names in parentheses.

Georg Brandlba83f822010-03-14 09:50:54 +00001870- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001871
Georg Brandlba83f822010-03-14 09:50:54 +00001872- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1873 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001874
Georg Brandlba83f822010-03-14 09:50:54 +00001875- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1876 decimal string that's guaranteed to round back to x under correct rounding
1877 (with round-half-to-even rounding mode). Previously it gave a string based on
1878 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1879 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1880 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001881
Georg Brandlba83f822010-03-14 09:50:54 +00001882- Issue #7117: On almost all platforms: float-to-string and string-to-float
1883 conversions within Python are now correctly rounded. Places these conversions
1884 occur include: str for floats and complex numbers; the float and complex
1885 constructors; old-style and new-style numeric formatting; serialization and
1886 deserialization of floats and complex numbers using marshal, pickle and json;
1887 parsing of float and imaginary literals in Python code; Decimal-to-float
1888 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001889
Georg Brandlba83f822010-03-14 09:50:54 +00001890 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1891 providing correctly-rounded strtod and dtoa C functions. This code is
1892 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1893 the C compiler. There may be a small number of platforms on which correct
1894 operation of this code cannot be guaranteed, so the code is not used: notably,
1895 this applies to platforms where the C double format is not IEEE 754 binary64,
1896 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1897 and Python's configure script is unable to determine how to change the FPU
1898 precision. On these platforms conversions use the platform strtod and dtoa,
1899 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001900
Georg Brandlba83f822010-03-14 09:50:54 +00001901- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1902 uses the correctly-rounded string <-> float conversions described above (when
1903 available), and so produces correctly rounded results that will display nicely
1904 under the float repr. There are two related small changes: (1) round now
1905 accepts any class with an ``__index__()`` method for its second argument (but
1906 no longer accepts floats for the second argument), and (2) an excessively
1907 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1908 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00001910- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1911
Georg Brandlba83f822010-03-14 09:50:54 +00001912- Fix several issues with ``compile()``. The input can now contain Windows and
1913 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001914
Georg Brandlba83f822010-03-14 09:50:54 +00001915- Remove length limitation when constructing a complex number from a unicode

1944 The tables for code points representing numeric values, white spaces or line
1945 breaks are now generated from the official Unicode Character Database files,
1946 and include information from the Unihan.txt file.

2057 but with at least one decimal point and with a default precision
2058 of 12. Previously, the behavior the same but with a default precision of 6.
2059 This more closely matches ``str()``, and reduces surprises when adding

3694 ``printf`` function, whereas PyString_FromFormat has an independent
3695 implementation and uses "%zd" on all platforms for size_t values.
3696 This makes a difference on win64, where ``printf`` needs "%Id" to display
3697 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003699- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3700 error.
3701
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003702- Issue #3777: long() applied to a float object now always return a long
3703 object; previously an int would be returned for small values. the __long__
3704 method is allowed to return either an int or a long, but the behaviour of
3705 float objects should not change to respect backward compatibility.
3706
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003707- Issue #3751: str.rpartition would perform a left-partition when called with
3708 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003712- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003713 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003714 was correctly parsed but parsing of subsequent arguments failed.
3715
Vinay Sajip35e3b032008-09-01 14:33:59 +00003716- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003717 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3718 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3719 when given a tuple of classes as second argument, were looking up
3720 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3721 type object.
3722
Neal Norwitz18aa3882008-08-24 05:04:52 +00003723- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003792 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3793 for catch_warnings() also led to an improvement in the raising of a
3794 DeprecationWarning related to warnings.warn_explicit().
3795

3822
Benjamin Peterson37346b22008-08-23 20:27:43 +00003823- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003860What's New in Python 2.6 beta 3?
3861================================
3862
Barry Warsaw07a4a382008-08-21 01:15:08 +00003863*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003864
3865Core and Builtins
3866-----------------
3867
Guido van Rossumf8402962008-08-20 15:01:50 +00003868- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3869 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3870 extensions do not automatically benefit from the class attribute
3871 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3872 to their tp_flags field if they care. This is a backwards
3873 compatibility feature; in 3.0, all types will use the cache by
3874 default.
3875
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003876- Keyword arguments can now follow starred arguments. (``f(a, *args,
3877 keyword=23)`` is now valid syntax.)
3878
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003879- ctypes function pointers that are COM methods have a boolean True
3880 value again.
3881
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003882- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3883 by denying s# to parse objects that have a releasebuffer procedure,
3884 and introducing s*.
3885
Georg Brandl1e13ea92008-08-11 09:07:59 +00003886- Issue #3537: Fix an assertion failure when an empty but presized dict
3887 object was stored in the freelist.
3888
Mark Dickinsonb6467572008-08-04 21:30:09 +00003889- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3890 ValueError consistently across platforms.
3891
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003892- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3893 (64bit Unix, for example), unichr() would truncate its argument and return
3894 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3895
Neal Norwitze7d8be82008-07-31 17:17:14 +00003896- Apply security patches from Apple.
3897
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003898- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3899 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3900
Antoine Pitrou92f82162008-07-25 22:22:08 +00003901- Issue #1819: function calls with several named parameters are now on
3902 average 35% faster (as measured by pybench).
3903
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003904- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3905 the python debugger steps into a class statement: the free variables (local
3906 variables defined in an outer scope) would be deleted from the outer scope.
3907
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003908- Issue #2620: Overflow checking when allocating or reallocating memory
3909 was not always being done properly in some python types and extension
3910 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3911 all been updated to perform better checks and places in the code that
3912 would previously leak memory on the error path when such an allocation
3913 failed have been fixed.

3919
Benjamin Petersone977ad42008-08-20 01:42:01 +00003920- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3921 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3922
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003923- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3924 version reported by these tools does not necessarily follow the python
3925 version numbering scheme, so the module is less strict when parsing it.
3926
Nick Coghlanf70385a2008-08-18 12:42:46 +00003927- Issue #2235: Added Py3k warnings for types which will become unhashable
3928 under the stricter __hash__ inheritance rules in 3.0. Several types
3929 which did not meet the rules for hash invariants and were already
3930 unhashable in 3.0 have now been explicitly flagged as unhashable in
3931 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3932 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3933
Brett Cannon88f801d2008-08-18 00:46:22 +00003934- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3935 imported into the module but exposed as part of the module's API.
3936
Brett Cannon7b96f072008-08-18 00:41:11 +00003937- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3938
Brett Cannon46225e72008-08-18 00:36:52 +00003939- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3942
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003943- Issue #3575: Incremental decoder's decode function now takes bytearray
3944 by using 's*' instead of 't#'.
3945
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003946- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003947 fails unicode conversion on 2nd parameter. (windows only)
3948
Georg Brandl222e2082010-08-01 22:27:39 +00003949- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003950 in a redirect.
3951

Brett Cannon721b1452008-08-16 22:00:27 +00003953 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003954
Facundo Batistaeb90b782008-08-16 14:44:07 +00003955- Issue #2776: fixed small issue when handling an URL with double slash
3956 after a 302 response in the case of not going through a proxy.
3957
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003958- Issue #2676: in the email package, content-type parsing was hanging on
3959 pathological input because of quadratic or exponential behaviour of a
3960 regular expression.
3961
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003962- Issue #3476: binary buffered reading through the new "io" library is now
3963 thread-safe.
3964
Brett Cannonbf3157b2008-08-14 05:00:03 +00003965- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3966 since mimetools itself is deprecated. Because modules are cached, all
3967 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3968
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003969- Issue #3134: shutil referenced undefined WindowsError symbol.
3970
Robert Schuppenies14646332008-08-10 11:01:53 +00003971- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3972 menu entries were not deleted.
3973
Brett Cannon83e81842008-08-09 23:30:55 +00003974- Copied the implementation of reduce() to _functools.reduce() to have a
3975 version that did not raise a DeprecationWarning under -3.
3976
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003977- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3978 a MemoryError rather than silently stop the iteration.

Guido van Rossum59ce9012008-08-09 14:55:34 +00003980- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3981 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00004003 asking for a specific length. This problem only affected files opened

4047
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004048- Issue #643841: The language reference now provides more detailed

4060-----------------
4061
Georg Brandl3e483f62008-07-16 22:57:41 +00004062- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4063 its methods now allow for items objects that can be converted to
4064 an integer using operator.index().
4065
Mark Dickinson64b7e502008-07-16 09:40:03 +00004066- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4067 produced a ValueError instead of giving the correct float.
4068
Eric Smitha5fa5a22008-07-16 00:11:49 +00004069- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4070 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4071
Mark Dickinson7103aa42008-07-15 19:08:33 +00004072- Issue #3008: the float type has a new instance method 'float.hex'
4073 and a new class method 'float.fromhex' to convert floating-point
4074 numbers to and from hexadecimal strings, respectively.
4075
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004076- Issue #2235: __hash__ is once again inherited by default. To allow
4077 collections.Hashable to remain meaningful in the presence of the
4078 default hash implementation (object.__hash__), it is now possible
4079 to explicit block inheritance of hash by setting __hash__=None at
4080 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4081 level.
4082
Nick Coghlanb028f502008-07-13 14:52:36 +00004083- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4084 the parent module cannot be found while performing an absolute import.
4085 This means that an incorrectly defined __package__ attribute will
4086 now only prevent relative imports in that module rather than causing
4087 all imports from that module to fail.
4088
Nick Coghlan14ff9942008-07-08 14:21:42 +00004089- Issue #2517: Allow unicode messages in Exceptions again by correctly

4099 another thread's dictionary.
4100
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004101- Issue #3004: Minor change to slice.indices(): the start and stop
4102 arguments are now treated identically, making the behaviour easier
4103 to describe and understand. For example, slice(None, -10,
4104 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4105 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4106 10, -1).
4107
Georg Brandl278fc502008-07-19 12:46:12 +00004108- Issue #3219: Calling a function with repeated keyword arguments,
4109 f(a=2, a=23), would not cause a syntax error. This was a regression
4110 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004112- Issue #2862: Make int and float freelist management consistent with
4113 other freelists. Changes their CompactFreeList apis into

4120 api functions without holding the GIL, which could lead to a fatal
4121 error when they failed.
4122
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004123- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004148- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4149 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004150 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004151 content-length. The problem had been corrected in the 2.4 branch, but never
4152 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004167- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4555
Brett Cannonb61d8012008-05-11 23:39:04 +00004556- ``Lib/lib-old`` is now added to sys.path.
4557
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004558- On MacOS X it is now possible to install the framework in 64-bit
4559 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004560 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004561
4562 This is controlled by the configure argument ``--with-universal-archs``:
4563
4564 - ``--with-universal-archs=all``: install 4-way universal
4565
4566 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4567
4568 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4569
4570 This option should be used in combination with ``--enable-universalsdk=``.
4571
4572 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004581
4582- The PyString functions have been renamed to PyBytes. A batch of
4583 defines were added so that the linker still sees the original
4584 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004622- Issue #1631171: Re-implement the 'warnings' module in C (the
4623 original Python code has been kept as backup). This will allow for
4624 using the 'warning's machinery in such places as the parser where
4625 use of pure Python code is not possible. Both the ``showarning()``
4626 and ``formatwarning()`` gain an optional 'line' argument which is
4627 not called by default for backwards-compatibility reasons. Setting
4628 ``warnings.showwarning()`` to an implementation that lacks support
4629 for the ``line`` argument will raise a DeprecationWarning.

4653
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004654- The getpass module has been improved on Unix. It now uses /dev/tty
4655 by default and uses stderr instead of stdout. A GetPassWarning is
4656 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004657

4669 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00004670
Georg Brandl3ee81df2008-05-17 18:14:43 +00004671- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004672 extension modules between 32 and 64 bit platforms. See the distutls

4676 threads at once without fear of crashing the Python interpreter. If
4677 file.close() is called while an object is in use by another thread
4678 an IOError exception will be raised and the file will not be closed.
4679
Thomas Hellerf7906482008-04-04 19:43:25 +00004680- The bundled libffi copy is now in sync with the recently released

4685 so the controlled environment will more closely mirror the typical
4686 script environment. This supports setup.py scripts that refer to
4687 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004692- Issue #2550: The approach used by client/server code for obtaining
4693 ports to listen on in network-oriented tests has been refined in an
4694 effort to facilitate running multiple instances of the entire
4695 regression test suite in parallel without issue.
4696 test_support.bind_port() has been fixed such that it will always
4697 return a unique port -- which wasn't always the case with the
4698 previous implementation, especially if socket options had been set
4699 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4700 new implementation of bind_port() will actually raise an exception
4701 if it is passed an AF_INET/SOCK_STREAM socket with either the
4702 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4703 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4704 the socket it's been passed. This currently only applies to
4705 Windows. This option prevents any other sockets from binding to the
4706 host/port we've bound to, thus removing the possibility of the
4707 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4708 when a second SOCK_STREAM socket binds and accepts to a host/port
4709 that's already been bound by another socket. The optional preferred
4710 port parameter to bind_port() has been removed. Under no
4711 circumstances should tests be hard coding ports!
4712
4713 test_support.find_unused_port() has also been introduced, which will
4714 pass a temporary socket object to bind_port() in order to obtain an
4715 unused port. The temporary socket object is then closed and
4716 deleted, and the port is returned. This method should only be used
4717 for obtaining an unused port in order to pass to an external program
4718 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4719 a parameter to a server-oriented class that doesn't give you direct
4720 access to the underlying socket used.
4721
4722 Finally, test_support.HOST has been introduced, which should be used
4723 for the host argument of any relevant socket calls (i.e. bind and
4724 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004725
4726 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004727 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004728 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4729 test_asynchat and test_socket_ssl.
4730
Georg Brandl3ee81df2008-05-17 18:14:43 +00004731 It is now possible for multiple instances of the regression test
4732 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005011- Added the future_builtins module, which contains hex() and oct().
5012 These are the PEP 3127 version of these functions, designed to be
5013 compatible with the hex() and oct() builtins from Python 3.0. They
5014 differ slightly in their output formats from the existing, unchanged
5015 Python 2.6 builtins. The expected usage of the future_builtins
5016 module is:
5017 from future_builtins import hex, oct
5018
Eric Smith7ef40bf2008-02-20 23:34:22 +00005019- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5020 exponents for exponents with absolute value < 100. Follows C99
5021 standard. This is a change on Windows, which would use 3 digits.
5022 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5023 so that any alterations it does to the resulting string will be
5024 available in stringlib/formatter.h (for float.__format__).
5025
Eric Smith5a3c1352008-02-19 13:21:56 +00005026- Implemented PEP 3101, Advanced String Formatting. This adds a new
5027 builtin format(); a format() method for str and unicode; a
5028 __format__() method to object, str, unicode, int, long, float, and
5029 datetime; the class string.Formatter; and the C API
5030 PyObject_Format().
5031
Georg Brandl3ee81df2008-05-17 18:14:43 +00005032- Fixed several potential crashes, all caused by specially crafted
5033 __del__ methods exploiting objects in temporarily inconsistent
5034 state.

5045 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005046
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047- Issue #2045: Fix an infinite recursion triggered when printing a
5048 subclass of collections.defaultdict, if its default_factory is set
5049 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005050
Christian Heimesf75dbef2008-02-08 00:11:31 +00005051- Fixed a minor memory leak in dictobject.c. The content of the free
5052 list was not freed on interpreter shutdown.
5053
Georg Brandl21e99f42010-03-07 15:23:59 +00005054- Limit free list of method and built-in function objects to 256

5058 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005059 to compact the internal free lists of pre-allocted ints and floats.
5060
Georg Brandl3ee81df2008-05-17 18:14:43 +00005061- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5062 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00005074- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5075 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005076
Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Patch #1473257: generator objects gain a gi_code attribute. This is
5078 the same object as the func_code attribute of the function that
5079 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005080
Georg Brandl3ee81df2008-05-17 18:14:43 +00005081- Issue #1920: "while 0" statements were completely removed by the
5082 compiler, even in the presence of an "else" clause, which is
5083 supposed to be run when the condition is false. Now the compiler
5084 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005085
Guido van Rossumeead05f2008-01-24 18:21:02 +00005086- A few crashers fixed: weakref_in_del.py (issue #1377858);
5087 loosing_dict_ref.py (issue #1303614, test67.py);
5088 borrowed_ref_[34].py (not in tracker).
5089
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005090- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005091 suppressed while an extension is loaded by calling SetErrorMode in
5092 dynload_win.c. The error is still reported properly.
5093
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005095 several extension methods and modules do not work without unicode
5096 support.
5097
Georg Brandl26543b12008-01-21 18:36:51 +00005098- Issue #1882: when compiling code from a string, encoding cookies in the
5099 second line of code were not always recognized correctly.
5100
Georg Brandl14404b62008-01-19 19:27:05 +00005101- Issue #1679: "0x" was taken as a valid integer literal.
5102
Georg Brandl6caad7d2008-01-26 14:19:22 +00005103- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005104 added.
5105
Christian Heimesc94e2b52008-01-14 04:13:37 +00005106- sys.float_info / PyFloat_GetInfo: The floating point information
5107 object was converted from a dict to a specialized structseq object.
5108
Georg Brandl3ee81df2008-05-17 18:14:43 +00005109- Patch #1816: Added sys.flags structseq. It exposes the status of
5110 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005111
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112- Objects/structseq.c: Implemented new structseq representation. The
5113 patch makes structseqs (e.g. the return value of os.stat) more
5114 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- Patch #1700288: added a type attribute cache that caches method
5117 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005118
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005119- Bug #1776: __import__() no longer accepts filenames on any platform.
5120 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005121
Georg Brandlaed6c662008-01-07 17:25:53 +00005122- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5125 envvar and sys.dont_write_bytecode attribute. All these can be set
5126 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Improve some exception messages when Windows fails to load an
5129 extension module. Now we get for example '%1 is not a valid Win32
5130 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005137- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005138 and INF. float("nan"), float("inf") and float("-inf") now work on
5139 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Compiler now generates simpler and faster code for dictionary
5142 literals. The oparg for BUILD_MAP now indicates an estimated
5143 dictionary size. There is a new opcode, STORE_MAP, for adding
5144 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Patch #1739468: Directories and zipfiles containing a __main__.py
5174 file can now be directly executed by passing their name to the
5175 interpreter. The directory/zipfile is automatically inserted as the
5176 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005177
Georg Brandl3ee81df2008-05-17 18:14:43 +00005178- Issue #1265: Fix a problem with sys.settrace, if the tracing
5179 function uses a generator expression when at the same time the
5180 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005181
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005182- sets and frozensets now have an isdisjoint() method.
5183
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005184- optimize the performance of builtin.sum().
5185
Neal Norwitz44f326e2007-10-05 05:29:17 +00005186- Fix warnings found by the new version of the Coverity checker.
5187
Georg Brandl21e99f42010-03-07 15:23:59 +00005188- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5190 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- Issue #1686386: Tuple's tp_repr did not take into account the
5193 possibility of having a self-referential tuple, which is possible
5194 from C code. Nor did object's tp_str consider that a type's tp_str
5195 could do something that could lead to an inifinite recursion.
5196 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5197 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005198
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199- Issue #1164: It was possible to trigger deadlock when using the
5200 'print' statement to write to a file since the GIL was not released
5201 as needed. Now PyObject_Print() does the right thing along with
5202 various tp_print implementations of the built-in types and those in
5203 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005204
Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Issue #1147: Exceptions were directly allowing string exceptions in
5206 their throw() method even though string exceptions no longer
5207 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005208
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209- Issue #1096: Prevent a segfault from getting the repr of a very
5210 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005211
Brett Cannon1e534b52007-09-07 04:18:30 +00005212- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005213 PyObject_Call() never calling back out to Python code to trigger
5214 recursion depth updates/checks. Required the creation of a static
5215 RuntimeError instance in case normalizing an exception put the
5216 recursion check value past its limit. Fixes crashers
5217 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005218
Georg Brandl3ee81df2008-05-17 18:14:43 +00005219- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005232- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233 __*__ attributes. (Some already existed, e.g., __doc__ and
5234 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005235
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005236- Add -3 option to the interpreter to warn about features that are
5237 deprecated and will be changed/removed in Python 3.0.
5238
Georg Brandl2134e752007-05-21 20:34:16 +00005239- Patch #1686487: you can now pass any mapping after '**' in function
5240 calls.
5241
Collin Winter62903052007-05-18 23:11:24 +00005242- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005243 "except E as target:". This is to provide forwards compatibility
5244 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005245
Brett Cannon229cee22007-05-05 01:34:02 +00005246- Deprecate BaseException.message as per PEP 352.
5247
Georg Brandl3ee81df2008-05-17 18:14:43 +00005248- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005249 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005250
Vinay Sajip8549ce32007-05-06 17:53:37 +00005251- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005252 setting a plain string, ie don't expand to single letter identifiers.
5253
Raymond Hettinger13936692007-04-11 18:40:58 +00005254- Request #1191699: Slices can now be pickled.
5255
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005256- Request #1193128: str.translate() now allows a None argument for
5257 translations that only remove characters without re-mapping the
5258 remaining characters.
5259
Georg Brandl5cb76c12007-03-21 09:00:39 +00005260- Patch #1682205: a TypeError while unpacking an iterable is no longer
5261 masked by a generic one with the message "unpack non-sequence".
5262
Neal Norwitzaa754b72007-03-21 06:39:48 +00005263- Remove unused file Python/fmod.c.
5264
Guido van Rossum143b5642007-03-23 04:58:42 +00005265- Bug #1683368: The object.__init__() and object.__new__() methods are
5266 now stricter in rejecting excess arguments. The only time when
5267 either allows excess arguments is when it is not overridden and the
5268 other one is. For backwards compatibility, when both are
5269 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005270 warning later). Also, type.__init__() insists on the same signature
5271 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005272
Georg Brandl3ee81df2008-05-17 18:14:43 +00005273- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5274 object to complex using its __complex__() method before falling back
5275 to the __float__() method. Therefore, the functions in the cmath
5276 module now can operate on objects that define a __complex__()
5277 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005279- Patch #1623563: allow __class__ assignment for classes with
5280 __slots__. The old and the new class are still required to have the
5281 same slot names.

5287 ``object.__reduce_ex__()`` is called with an object that is faking
5288 its type.

5294
Georg Brandl7b9c5552007-03-12 14:30:05 +00005295- Bug #1678647: write a newline after printing an exception in any
5296 case, even when converting the value to a string failed.
5297
Georg Brandl871f1bc2007-03-12 13:17:36 +00005298- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005299 its argument, if it exists. If not, it will work like before. This
5300 allows customizing the output of dir() in the presence of a
5301 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00005416- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005434 generator expressions (x for x, in ... ) works again. Fixing this
5435 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00005475- Removed uses of dict.has_key() from distutils, and uses of

Facundo Batistad918a652007-04-24 13:54:38 +00005824- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005866 AttributeError instead of an IOError when the server's response
5867 didn't contain a valid HTTP status line.

5958 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006351 time so that opening a database previously created with the DB_DUP
6352 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6353 opens. Specifically: dictionary assignment to a DB object will
6354 replace all values for a given key when the database allows
6355 duplicate values. DB users should use DB.put(k, v) when they want
6356 to store duplicates; not DB[k] = v.

6365 behavior of quoting dots if they are the second character of any
6366 line.
