259 This prevents user-created self-referencing ordered dictionaries from
260 becoming permanently uncollectable GC garbage. The downside is that

272 original error is re-raised.

295 character years even if the message contains RFC822 two character years.
296
Daniel Stutzbach91287322010-08-24 21:09:30 +0000297- Issue #8750: Fixed MutableSet's methods to correctly handle

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000721- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
722 start byte and the continuation byte(s) are now considered invalid, instead
723 of the number of bytes specified by the start byte.
724 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
725 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
726 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
727 Previous versions returned a single u'\ufffd'.

736 objects. (1) The comparison could incorrectly return True in some cases
737 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
738 (2) The comparison raised an OverflowError for large integers, leading

1126 supplied a format string. This will be changed to a DeprecationWaring in

1178 InvalidOperation instead of returning False. (Comparisons involving a quiet
1179 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1180 signaling NaNs remain unhashable.

1200 Fractions instance now raise TypeError instead of returning True/False. This
1201 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1202 <=> complex, and complex <=> complex comparisons.

Antoine Pitroud840e512010-02-04 20:20:18 +00001608- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001615- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001616 file position when calling `truncate()`. It would previously change the file
1617 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001618 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00001620- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1621 class used to represent files stored inside an archive. The new
1622 implementation is significantly faster and can be wrapped in a
1623 ``io.BufferedReader`` object for more speedups. It also solves an issue
1624 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1713-----------------
1714
Georg Brandlba83f822010-03-14 09:50:54 +00001715- The ``__complex__()`` method is now looked up on the class of instances to
1716 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001718- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1719 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1720
Mark Dickinson1b34d252010-01-01 17:27:30 +00001721- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001722 DeprecationWarning when passed a float argument where an integer was expected.
1723 These functions and methods now raise TypeError instead. The majority of the
1724 effects of this change are in the extension modules, but some core functions
1725 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1726 and many unicode/str methods.

1740 of integers: the result of a/b is now correctly rounded for ints a and b (at
1741 least on IEEE 754 platforms), and in particular does not depend on the
1742 internal representation of a long.

1750
Georg Brandlba83f822010-03-14 09:50:54 +00001751 These executables now work properly with the arch(1) command: ``arch -ppc
1752 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001891- Issue #3382: 'F' formatting for float and complex now convert the result to
1892 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1893 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001894
Georg Brandlba83f822010-03-14 09:50:54 +00001895- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1896 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001897
Georg Brandlba83f822010-03-14 09:50:54 +00001898- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1899 1e-100 used to raise OverflowError, but now gives the requested 120
1900 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001908
Georg Brandlba83f822010-03-14 09:50:54 +00001909- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1910 decimal string that's guaranteed to round back to x under correct rounding
1911 (with round-half-to-even rounding mode). Previously it gave a string based on
1912 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1913 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1914 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001915
Georg Brandlba83f822010-03-14 09:50:54 +00001916- Issue #7117: On almost all platforms: float-to-string and string-to-float
1917 conversions within Python are now correctly rounded. Places these conversions
1918 occur include: str for floats and complex numbers; the float and complex
1919 constructors; old-style and new-style numeric formatting; serialization and
1920 deserialization of floats and complex numbers using marshal, pickle and json;
1921 parsing of float and imaginary literals in Python code; Decimal-to-float
1922 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001923
Georg Brandlba83f822010-03-14 09:50:54 +00001924 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1925 providing correctly-rounded strtod and dtoa C functions. This code is
1926 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1927 the C compiler. There may be a small number of platforms on which correct
1928 operation of this code cannot be guaranteed, so the code is not used: notably,
1929 this applies to platforms where the C double format is not IEEE 754 binary64,
1930 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1931 and Python's configure script is unable to determine how to change the FPU
1932 precision. On these platforms conversions use the platform strtod and dtoa,
1933 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001934
Georg Brandlba83f822010-03-14 09:50:54 +00001935- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1936 uses the correctly-rounded string <-> float conversions described above (when
1937 available), and so produces correctly rounded results that will display nicely
1938 under the float repr. There are two related small changes: (1) round now
1939 accepts any class with an ``__index__()`` method for its second argument (but
1940 no longer accepts floats for the second argument), and (2) an excessively
1941 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1942 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002084
Georg Brandlba83f822010-03-14 09:50:54 +00002085 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2086 (2) parsing of strings representing infinities and nans was locale aware; and
2087 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002089- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2090 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2091 but with at least one decimal point and with a default precision
2092 of 12. Previously, the behavior the same but with a default precision of 6.
2093 This more closely matches ``str()``, and reduces surprises when adding
2094 alignment flags to the empty presentation type. This also affects the new
2095 complex.__format__ in the same way.
2096
2097- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003581 leak-chasing test runs give sensible results. The previous method of reaping
3582 threads could return successfully while some Thread objects were still
3583 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00003703- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003704 AttributeError instead of RuntimeError, depending in which C API call
3705 exactly the recursion limit is exceeded. Consequently, both exception types
3706 are caught and silenced.

3722
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003723- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3724
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003725- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3726 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3727 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3728 ``printf`` function, whereas PyString_FromFormat has an independent
3729 implementation and uses "%zd" on all platforms for size_t values.
3730 This makes a difference on win64, where ``printf`` needs "%Id" to display
3731 64bit values.
3732
Benjamin Peterson97179b02008-09-09 20:55:01 +00003733- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3734 error.
3735
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003736- Issue #3777: long() applied to a float object now always return a long
3737 object; previously an int would be returned for small values. the __long__
3738 method is allowed to return either an int or a long, but the behaviour of
3739 float objects should not change to respect backward compatibility.
3740
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003741- Issue #3751: str.rpartition would perform a left-partition when called with
3742 a unicode argument.
3743
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003744- Issue #3683: Fix compilation when --without-threads is given.
3745
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003746- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003747 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003748 was correctly parsed but parsing of subsequent arguments failed.
3749
Vinay Sajip35e3b032008-09-01 14:33:59 +00003750- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003751 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3752 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3753 when given a tuple of classes as second argument, were looking up
3754 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3755 type object.
3756
Neal Norwitz18aa3882008-08-24 05:04:52 +00003757- Fix crashes on memory allocation failure found with failmalloc.
3758
3759- Fix memory leaks found with valgrind and update suppressions file.
3760
3761- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3762
3763- Fix problem using wrong name in decimal module reported by pychecker.
3764
Christian Heimes7d4c3172008-08-22 19:47:25 +00003765- Silenced another compiler warning about a used but not defined
3766 function 'stringlib_contains_obj'.
3767
Benjamin Peterson712ee922008-08-24 18:10:20 +00003768- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3769 ``__delslice__``.
3770
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003771- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3772 library targets in the Makefile.
3773
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003774- Issue #1204: The configure script now tests for additional libraries
3775 that may be required when linking against readline. This fixes issues
3776 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

3787 stack usage in the case of deeply nested objects.
3788

Nick Coghland2e09382008-09-11 12:11:06 +00003799- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003800 return a list or None rather than a custom object.
3801
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003802- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003826 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3827 for catch_warnings() also led to an improvement in the raising of a
3828 DeprecationWarning related to warnings.warn_explicit().
3829
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003830- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003853- Issue #2975: When compiling several extension modules with Visual Studio 2008
3854 from the same python interpreter, some environment variables would grow
3855 without limit.
3856
Benjamin Peterson37346b22008-08-23 20:27:43 +00003857- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3858 exploitation of poor argument checking.

3900-----------------
3901
Guido van Rossumf8402962008-08-20 15:01:50 +00003902- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3903 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3904 extensions do not automatically benefit from the class attribute
3905 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3906 to their tp_flags field if they care. This is a backwards
3907 compatibility feature; in 3.0, all types will use the cache by
3908 default.
3909
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003910- Keyword arguments can now follow starred arguments. (``f(a, *args,
3911 keyword=23)`` is now valid syntax.)
3912
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003913- ctypes function pointers that are COM methods have a boolean True
3914 value again.
3915
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003916- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3917 by denying s# to parse objects that have a releasebuffer procedure,
3918 and introducing s*.
3919
Georg Brandl1e13ea92008-08-11 09:07:59 +00003920- Issue #3537: Fix an assertion failure when an empty but presized dict
3921 object was stored in the freelist.
3922
Mark Dickinsonb6467572008-08-04 21:30:09 +00003923- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3924 ValueError consistently across platforms.
3925
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003926- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3927 (64bit Unix, for example), unichr() would truncate its argument and return
3928 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3929
Neal Norwitze7d8be82008-07-31 17:17:14 +00003930- Apply security patches from Apple.
3931
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003932- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3933 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3934
Antoine Pitrou92f82162008-07-25 22:22:08 +00003935- Issue #1819: function calls with several named parameters are now on
3936 average 35% faster (as measured by pybench).
3937
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003938- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3939 the python debugger steps into a class statement: the free variables (local
3940 variables defined in an outer scope) would be deleted from the outer scope.
3941
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003942- Issue #2620: Overflow checking when allocating or reallocating memory
3943 was not always being done properly in some python types and extension
3944 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3945 all been updated to perform better checks and places in the code that
3946 would previously leak memory on the error path when such an allocation
3947 failed have been fixed.

3951
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003952- Issue #3612: Added some missing basic types in ctypes.wintypes.
3953
Benjamin Petersone977ad42008-08-20 01:42:01 +00003954- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3955 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3956
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003957- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3958 version reported by these tools does not necessarily follow the python
3959 version numbering scheme, so the module is less strict when parsing it.
3960
Nick Coghlanf70385a2008-08-18 12:42:46 +00003961- Issue #2235: Added Py3k warnings for types which will become unhashable
3962 under the stricter __hash__ inheritance rules in 3.0. Several types
3963 which did not meet the rules for hash invariants and were already
3964 unhashable in 3.0 have now been explicitly flagged as unhashable in
3965 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3966 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3967
Brett Cannon88f801d2008-08-18 00:46:22 +00003968- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3969 imported into the module but exposed as part of the module's API.
3970
Brett Cannon7b96f072008-08-18 00:41:11 +00003971- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3972
Brett Cannon46225e72008-08-18 00:36:52 +00003973- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003975- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3976
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003977- Issue #3575: Incremental decoder's decode function now takes bytearray
3978 by using 's*' instead of 't#'.

4081
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004082- Issue #643841: The language reference now provides more detailed

4095
Georg Brandl3e483f62008-07-16 22:57:41 +00004096- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4097 its methods now allow for items objects that can be converted to
4098 an integer using operator.index().
4099
Mark Dickinson64b7e502008-07-16 09:40:03 +00004100- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4101 produced a ValueError instead of giving the correct float.
4102
Eric Smitha5fa5a22008-07-16 00:11:49 +00004103- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4104 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4105
Mark Dickinson7103aa42008-07-15 19:08:33 +00004106- Issue #3008: the float type has a new instance method 'float.hex'
4107 and a new class method 'float.fromhex' to convert floating-point
4108 numbers to and from hexadecimal strings, respectively.
4109
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004110- Issue #2235: __hash__ is once again inherited by default. To allow
4111 collections.Hashable to remain meaningful in the presence of the
4112 default hash implementation (object.__hash__), it is now possible
4113 to explicit block inheritance of hash by setting __hash__=None at
4114 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4115 level.
4116
Nick Coghlanb028f502008-07-13 14:52:36 +00004117- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4118 the parent module cannot be found while performing an absolute import.
4119 This means that an incorrectly defined __package__ attribute will
4120 now only prevent relative imports in that module rather than causing
4121 all imports from that module to fail.
4122
Nick Coghlan14ff9942008-07-08 14:21:42 +00004123- Issue #2517: Allow unicode messages in Exceptions again by correctly

4133 another thread's dictionary.
4134
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004135- Issue #3004: Minor change to slice.indices(): the start and stop
4136 arguments are now treated identically, making the behaviour easier
4137 to describe and understand. For example, slice(None, -10,
4138 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4139 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4140 10, -1).
4141
Georg Brandl278fc502008-07-19 12:46:12 +00004142- Issue #3219: Calling a function with repeated keyword arguments,
4143 f(a=2, a=23), would not cause a syntax error. This was a regression
4144 from 2.4 caused by the switch to the new compiler.

4183 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004184 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004185 content-length. The problem had been corrected in the 2.4 branch, but never

4545 suitable sign) if n is large and negative; previously, it raised
4546 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004592- On MacOS X it is now possible to install the framework in 64-bit
4593 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004594 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004595
4596 This is controlled by the configure argument ``--with-universal-archs``:
4597
4598 - ``--with-universal-archs=all``: install 4-way universal
4599
4600 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4601
4602 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4603
4604 This option should be used in combination with ``--enable-universalsdk=``.
4605
4606 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 +00004656- Issue #1631171: Re-implement the 'warnings' module in C (the
4657 original Python code has been kept as backup). This will allow for
4658 using the 'warning's machinery in such places as the parser where
4659 use of pure Python code is not possible. Both the ``showarning()``
4660 and ``formatwarning()`` gain an optional 'line' argument which is
4661 not called by default for backwards-compatibility reasons. Setting
4662 ``warnings.showwarning()`` to an implementation that lacks support
4663 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004726- Issue #2550: The approach used by client/server code for obtaining
4727 ports to listen on in network-oriented tests has been refined in an
4728 effort to facilitate running multiple instances of the entire
4729 regression test suite in parallel without issue.
4730 test_support.bind_port() has been fixed such that it will always
4731 return a unique port -- which wasn't always the case with the
4732 previous implementation, especially if socket options had been set
4733 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4734 new implementation of bind_port() will actually raise an exception
4735 if it is passed an AF_INET/SOCK_STREAM socket with either the
4736 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4737 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4738 the socket it's been passed. This currently only applies to
4739 Windows. This option prevents any other sockets from binding to the
4740 host/port we've bound to, thus removing the possibility of the
4741 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4742 when a second SOCK_STREAM socket binds and accepts to a host/port
4743 that's already been bound by another socket. The optional preferred
4744 port parameter to bind_port() has been removed. Under no
4745 circumstances should tests be hard coding ports!
4746
4747 test_support.find_unused_port() has also been introduced, which will
4748 pass a temporary socket object to bind_port() in order to obtain an
4749 unused port. The temporary socket object is then closed and
4750 deleted, and the port is returned. This method should only be used
4751 for obtaining an unused port in order to pass to an external program
4752 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4753 a parameter to a server-oriented class that doesn't give you direct
4754 access to the underlying socket used.
4755
4756 Finally, test_support.HOST has been introduced, which should be used
4757 for the host argument of any relevant socket calls (i.e. bind and
4758 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004759
4760 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004761 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004762 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4763 test_asynchat and test_socket_ssl.
4764
Georg Brandl3ee81df2008-05-17 18:14:43 +00004765 It is now possible for multiple instances of the regression test
4766 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00004820- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4822 Plane. This affected raw unicode literals and the
4823 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4824 this case, like normal unicode literals and the 'unicode-escape'
4825 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005045- Added the future_builtins module, which contains hex() and oct().
5046 These are the PEP 3127 version of these functions, designed to be
5047 compatible with the hex() and oct() builtins from Python 3.0. They
5048 differ slightly in their output formats from the existing, unchanged
5049 Python 2.6 builtins. The expected usage of the future_builtins
5050 module is:
5051 from future_builtins import hex, oct
5052
Eric Smith7ef40bf2008-02-20 23:34:22 +00005053- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5054 exponents for exponents with absolute value < 100. Follows C99
5055 standard. This is a change on Windows, which would use 3 digits.
5056 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5057 so that any alterations it does to the resulting string will be
5058 available in stringlib/formatter.h (for float.__format__).
5059
Eric Smith5a3c1352008-02-19 13:21:56 +00005060- Implemented PEP 3101, Advanced String Formatting. This adds a new
5061 builtin format(); a format() method for str and unicode; a
5062 __format__() method to object, str, unicode, int, long, float, and
5063 datetime; the class string.Formatter; and the C API
5064 PyObject_Format().
5065
Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- Fixed several potential crashes, all caused by specially crafted
5067 __del__ methods exploiting objects in temporarily inconsistent
5068 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005069
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005070- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005071 prevent a possible crash: an Abstract Base Class would try to access
5072 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005073

Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Clear all free lists during a gc.collect() of the highest generation
5078 in order to allow pymalloc to free more arenas. Python may give back
5079 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005080
Georg Brandl3ee81df2008-05-17 18:14:43 +00005081- Issue #2045: Fix an infinite recursion triggered when printing a
5082 subclass of collections.defaultdict, if its default_factory is set
5083 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005084
Christian Heimesf75dbef2008-02-08 00:11:31 +00005085- Fixed a minor memory leak in dictobject.c. The content of the free
5086 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005088- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005090
Georg Brandl3ee81df2008-05-17 18:14:43 +00005091- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5092 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005093 to compact the internal free lists of pre-allocted ints and floats.
5094
Georg Brandl3ee81df2008-05-17 18:14:43 +00005095- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5096 calls. Python expected the return type int but the fork familie
5097 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Patch #1473257: generator objects gain a gi_code attribute. This is
5112 the same object as the func_code attribute of the function that
5113 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005114
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115- Issue #1920: "while 0" statements were completely removed by the
5116 compiler, even in the presence of an "else" clause, which is
5117 supposed to be run when the condition is false. Now the compiler
5118 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005119
Guido van Rossumeead05f2008-01-24 18:21:02 +00005120- A few crashers fixed: weakref_in_del.py (issue #1377858);
5121 loosing_dict_ref.py (issue #1303614, test67.py);
5122 borrowed_ref_[34].py (not in tracker).
5123
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005124- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005125 suppressed while an extension is loaded by calling SetErrorMode in
5126 dynload_win.c. The error is still reported properly.
5127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005129 several extension methods and modules do not work without unicode
5130 support.
5131
Georg Brandl26543b12008-01-21 18:36:51 +00005132- Issue #1882: when compiling code from a string, encoding cookies in the

5136
Georg Brandl6caad7d2008-01-26 14:19:22 +00005137- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005138 added.
5139
Christian Heimesc94e2b52008-01-14 04:13:37 +00005140- sys.float_info / PyFloat_GetInfo: The floating point information
5141 object was converted from a dict to a specialized structseq object.
5142
Georg Brandl3ee81df2008-05-17 18:14:43 +00005143- Patch #1816: Added sys.flags structseq. It exposes the status of
5144 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005145
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Objects/structseq.c: Implemented new structseq representation. The
5147 patch makes structseqs (e.g. the return value of os.stat) more
5148 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005149
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150- Patch #1700288: added a type attribute cache that caches method
5151 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005152
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005153- Bug #1776: __import__() no longer accepts filenames on any platform.

5159 envvar and sys.dont_write_bytecode attribute. All these can be set
5160 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005161
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- Improve some exception messages when Windows fails to load an
5163 extension module. Now we get for example '%1 is not a valid Win32
5164 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005165

Christian Heimes0a8143f2007-12-18 23:22:54 +00005171- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005172 and INF. float("nan"), float("inf") and float("-inf") now work on
5173 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005174
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175- Compiler now generates simpler and faster code for dictionary
5176 literals. The oparg for BUILD_MAP now indicates an estimated
5177 dictionary size. There is a new opcode, STORE_MAP, for adding
5178 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Patch #1739468: Directories and zipfiles containing a __main__.py
5208 file can now be directly executed by passing their name to the
5209 interpreter. The directory/zipfile is automatically inserted as the
5210 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005211
Georg Brandl3ee81df2008-05-17 18:14:43 +00005212- Issue #1265: Fix a problem with sys.settrace, if the tracing
5213 function uses a generator expression when at the same time the
5214 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005215
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005216- sets and frozensets now have an isdisjoint() method.
5217
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005218- optimize the performance of builtin.sum().

5221
Georg Brandl21e99f42010-03-07 15:23:59 +00005222- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005223 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5224 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005225
Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Issue #1686386: Tuple's tp_repr did not take into account the
5227 possibility of having a self-referential tuple, which is possible
5228 from C code. Nor did object's tp_str consider that a type's tp_str
5229 could do something that could lead to an inifinite recursion.
5230 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5231 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005232
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233- Issue #1164: It was possible to trigger deadlock when using the
5234 'print' statement to write to a file since the GIL was not released
5235 as needed. Now PyObject_Print() does the right thing along with
5236 various tp_print implementations of the built-in types and those in
5237 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005238
Georg Brandl3ee81df2008-05-17 18:14:43 +00005239- Issue #1147: Exceptions were directly allowing string exceptions in
5240 their throw() method even though string exceptions no longer
5241 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005242
Georg Brandl3ee81df2008-05-17 18:14:43 +00005243- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00005245
Brett Cannon1e534b52007-09-07 04:18:30 +00005246- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005247 PyObject_Call() never calling back out to Python code to trigger
5248 recursion depth updates/checks. Required the creation of a static
5249 RuntimeError instance in case normalizing an exception put the
5250 recursion check value past its limit. Fixes crashers
5251 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005252

Neal Norwitz0ac60192007-05-27 04:08:54 +00005266- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005267 __*__ attributes. (Some already existed, e.g., __doc__ and
5268 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005269
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005270- Add -3 option to the interpreter to warn about features that are

5272
Georg Brandl2134e752007-05-21 20:34:16 +00005273- Patch #1686487: you can now pass any mapping after '**' in function
5274 calls.
5275
Collin Winter62903052007-05-18 23:11:24 +00005276- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005277 "except E as target:". This is to provide forwards compatibility
5278 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005282- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005283 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005284
Vinay Sajip8549ce32007-05-06 17:53:37 +00005285- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005286 setting a plain string, ie don't expand to single letter identifiers.
5287
Raymond Hettinger13936692007-04-11 18:40:58 +00005288- Request #1191699: Slices can now be pickled.
5289
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005290- Request #1193128: str.translate() now allows a None argument for
5291 translations that only remove characters without re-mapping the
5292 remaining characters.
5293
Georg Brandl5cb76c12007-03-21 09:00:39 +00005294- Patch #1682205: a TypeError while unpacking an iterable is no longer

5298
Guido van Rossum143b5642007-03-23 04:58:42 +00005299- Bug #1683368: The object.__init__() and object.__new__() methods are
5300 now stricter in rejecting excess arguments. The only time when
5301 either allows excess arguments is when it is not overridden and the
5302 other one is. For backwards compatibility, when both are
5303 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005304 warning later). Also, type.__init__() insists on the same signature
5305 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5308 object to complex using its __complex__() method before falling back
5309 to the __float__() method. Therefore, the functions in the cmath
5310 module now can operate on objects that define a __complex__()
5311 method.

5331
Georg Brandl871f1bc2007-03-12 13:17:36 +00005332- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005333 its argument, if it exists. If not, it will work like before. This
5334 allows customizing the output of dir() in the presence of a
5335 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005347- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005348 makes the filenames the warning module prints much more sensible
5349 when a PYTHONSTARTUP file is used.

5363 sq_ass_slice instead of the sq_slice slot.
5364
Georg Brandl3ee81df2008-05-17 18:14:43 +00005365- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00005417- Bug #1545497: when given an explicit base, int() did ignore NULs
5418 embedded in the string to convert.
5419
Georg Brandl846f73a2006-10-08 07:11:54 +00005420- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005468 generator expressions (x for x, in ... ) works again. Fixing this
5469 problem required changing the .pyc magic number. This means that
5470 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006273- The implementation of UnicodeError objects has been simplified
6274 (start and end attributes are now stored directly as Py_ssize_t
6275 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00006276
Georg Brandl3ee81df2008-05-17 18:14:43 +00006277- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6278 with RFC 3207 and forgets any knowledge obtained from the server not
6279 obtained from the TLS negotiation itself. Patch contributed by Bill
6280 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006283 that the SMTP.starttls() caller no longer needs to call ehlo()
6284 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006285 does not claim to support starttls. Adds the
6286 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6287 Fenner.

6356 contents before adding elements from the iterable. This fix brings
6357 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00006358
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359- Added wide char functions to msvcrt module: getwch, getwche, putwch

6367 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6368 silently miscode subclasses of those types. Now, it raises a
6369 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006370

Georg Brandl3ee81df2008-05-17 18:14:43 +00006385 time so that opening a database previously created with the DB_DUP
6386 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6387 opens. Specifically: dictionary assignment to a DB object will
6388 replace all values for a given key when the database allows
6389 duplicate values. DB users should use DB.put(k, v) when they want
6390 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006391

6397 characters with ASCII value less than 32. Also, it correctly quotes
6398 dots only if they occur on a single line, as opposed to the previous
6399 behavior of quoting dots if they are the second character of any
6400 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006401
