Antoine Pitrou2c7d6852010-09-23 19:55:24 +000096- Issue #9928: Properly initialize the types exported by the bz2 module.
97
Antoine Pitrou6391b342010-09-14 18:48:19 +000098- Issue #9854: The default read() implementation in io.RawIOBase now
99 handles non-blocking readinto() returning None correctly.
100
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000101- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
102 SSLSocket.sendto() to match the corresponding socket methods. Also,
103 fix various SSLSocket methods to raise socket.error rather than an
104 unhelpful TypeError when called on an unconnected socket. Original patch
105 by Andrew Bennetts.
106
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000107- Issue #9826: OrderedDict.__repr__ can now handle self-referential

Raymond Hettinger20397532010-09-12 02:11:45 +0000115- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
116 This prevents user-created self-referencing ordered dictionaries from
117 becoming permanently uncollectable GC garbage. The downside is that
118 removing __del__ means that the internal doubly-linked list has to wait for
119 GC collection rather than freeing memory immediately when the refcnt drops
120 to zero.
121
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000122- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000123 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000124 value.
125
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000126- Issue #9792: In case of connection failure, socket.create_connection()
127 would swallow the exception and raise a new one, making it impossible
128 to fetch the original errno, or to filter timeout errors. Now the
129 original error is re-raised.
130
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000131- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
132 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
133 be updated back after the system call. Original patch by Brian Brazil.
134
Antoine Pitroudca9de92010-09-04 17:52:26 +0000135- Issue #1100562: Fix deep-copying of objects derived from the list and
136 dict types. Patch by Michele Orrù and Björn Lindqvist.
137

139 ConfigParser.write.
140
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000141- Issue #808164: Fixed socket.close to avoid references to globals, to
142 avoid issues when socket.close is called from a __del__ method.
143
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000144- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

148 character years even if the message contains RFC822 two character years.
149
Daniel Stutzbach91287322010-08-24 21:09:30 +0000150- Issue #8750: Fixed MutableSet's methods to correctly handle
151 reflexive operations, namely x -= x and x ^= x.
152
Victor Stinnercaafd772010-09-08 10:51:01 +0000153- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000154 error handling when accepting a new connection.
155

162 module now correctly return a set. (Patch by Eli Bendersky.)
163
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000164- Issue #9617: Signals received during a low-level write operation aren't
165 ignored by the buffered IO layer anymore.
166
Benjamin Peterson52c36052010-08-21 03:03:22 +0000167- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
168 are not held onto after they are deleted elsewhere.
169
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000170- Issue #9626: the view methods for collections.OrderedDict() were returning
171 the unordered versions inherited from dict. Those methods are now
172 overridden to provide ordered views.
173
Éric Araujo0389ae62010-08-14 03:07:46 +0000174- Issue #8688: MANIFEST files created by distutils now include a magic

568 start byte and the continuation byte(s) are now considered invalid, instead
569 of the number of bytes specified by the start byte.
570 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000928 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
929 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
930 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

950Core and Builtins
951-----------------
952
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000953- Issue #7301: Add environment variable $PYTHONWARNINGS.
954
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000955- Issue #8329: Don't return the same lists from select.select when no fds are
956 changed.
957
Georg Brandlfee0f442010-05-22 21:26:21 +0000958- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000959 on 64-bit machines. The shift count for either left or right shift is
960 permitted to be up to sys.maxsize.
961
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000962- Ensure that tokenization of identifiers is not affected by locale.

967
Georg Brandlfee0f442010-05-22 21:26:21 +0000968- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
969 with a non-empty format string. This is an effort to future-proof user
970 code. If a derived class does not currently implement __format__ but later
971 adds its own __format__, it would most likely break user code that had
972 supplied a format string. This will be changed to a DeprecationWaring in
973 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000974
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000975- Issue #8268: Old-style classes (not just instances) now support weak

999
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001000- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001001 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

1005
Georg Brandlfee0f442010-05-22 21:26:21 +00001006- Issue #8257: The Decimal construct now accepts a float instance directly,
1007 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001008
1009 >>> Decimal(1.1)
1010 Decimal('1.100000000000000088817841970012523233890533447265625')
1011
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001012- collections.Counter() now supports a subtract() method.
1013
Georg Brandlfee0f442010-05-22 21:26:21 +00001014- The functools module now has a total_ordering() class decorator to simplify
1015 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001016
Georg Brandlfee0f442010-05-22 21:26:21 +00001017- The functools module also adds cmp_to_key() as a tool to transition old-style
1018 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001019
Georg Brandlfee0f442010-05-22 21:26:21 +00001020- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1021 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001022
Georg Brandlfee0f442010-05-22 21:26:21 +00001023- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1024 InvalidOperation instead of returning False. (Comparisons involving a quiet
1025 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1026 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001027
Georg Brandlfee0f442010-05-22 21:26:21 +00001028- Issue #2531: Comparison operations between floats and Decimal instances now
1029 return a result based on the numeric values of the operands; previously they
1030 returned an arbitrary result based on the relative ordering of id(float) and
1031 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001032
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001033- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001034 argument `-` which tells it to read files to compile from stdin. Each line is
1035 read on demand and the named file is compiled immediately. (Original patch by
1036 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001037
Georg Brandlfee0f442010-05-22 21:26:21 +00001038- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001041- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1042 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001043 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001044
Georg Brandlfee0f442010-05-22 21:26:21 +00001045- Comparisons using one of <, <=, >, >= between a complex instance and a
1046 Fractions instance now raise TypeError instead of returning True/False. This
1047 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1048 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001049

Georg Brandlfee0f442010-05-22 21:26:21 +00001155 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1156 inconsistent: __int__ was used for some integer codes but not for others, and
1157 the set of integer codes for which it was used differed between native packing
1158 and standard packing.)

1402 and add the additional members returned in an OSVERSIONINFOEX structure. The
1403 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001406- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1407 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1408 returning NULL. The macro now returns a statically allocated empty string
1409 instead.

1419 strings,
1420 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1421 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00001454- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001455 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001456 Also, raise ValueError rather than TypeError when an unknown TIPC address
1457 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001461- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001462 file position when calling `truncate()`. It would previously change the file
1463 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001464 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1465
Georg Brandlba83f822010-03-14 09:50:54 +00001466- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1467 class used to represent files stored inside an archive. The new
1468 implementation is significantly faster and can be wrapped in a
1469 ``io.BufferedReader`` object for more speedups. It also solves an issue
1470 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1471 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001481- Issue #7748: Since unicode values are supported for some metadata options in
1482 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1483 encoded string for them. This ensures that the upload and register commands
1484 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001755- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1756 decimal string that's guaranteed to round back to x under correct rounding
1757 (with round-half-to-even rounding mode). Previously it gave a string based on
1758 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1759 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1760 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001761
Georg Brandlba83f822010-03-14 09:50:54 +00001762- Issue #7117: On almost all platforms: float-to-string and string-to-float
1763 conversions within Python are now correctly rounded. Places these conversions
1764 occur include: str for floats and complex numbers; the float and complex
1765 constructors; old-style and new-style numeric formatting; serialization and
1766 deserialization of floats and complex numbers using marshal, pickle and json;
1767 parsing of float and imaginary literals in Python code; Decimal-to-float
1768 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001769
Georg Brandlba83f822010-03-14 09:50:54 +00001770 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1771 providing correctly-rounded strtod and dtoa C functions. This code is
1772 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1773 the C compiler. There may be a small number of platforms on which correct
1774 operation of this code cannot be guaranteed, so the code is not used: notably,
1775 this applies to platforms where the C double format is not IEEE 754 binary64,
1776 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1777 and Python's configure script is unable to determine how to change the FPU
1778 precision. On these platforms conversions use the platform strtod and dtoa,
1779 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001781- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1782 uses the correctly-rounded string <-> float conversions described above (when
1783 available), and so produces correctly rounded results that will display nicely
1784 under the float repr. There are two related small changes: (1) round now
1785 accepts any class with an ``__index__()`` method for its second argument (but
1786 no longer accepts floats for the second argument), and (2) an excessively
1787 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1788 raises an exception.

1937 but with at least one decimal point and with a default precision
1938 of 12. Previously, the behavior the same but with a default precision of 6.
1939 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00002050- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002051 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00002081- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2082 existing .py counterpart, override the co_filename attributes of all code
2083 objects if the original filename is obsolete (which can happen if the file has

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002129- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2131 instead of throwing a MemoryError.
2132
Georg Brandlba83f822010-03-14 09:50:54 +00002133- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2138
Georg Brandlba83f822010-03-14 09:50:54 +00002139- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2140 file objects with closefd=False. The file descriptor is still kept open but
2141 the file object behaves like a closed file. The ``FileIO`` object also got a
2142 new readonly attribute ``closefd``.

2161
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002162- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002163 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002165- On windows, ``os.chdir()`` given unicode was not working if
2166 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2167 this code path is really executed because I cannot move to such directory on
2168 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002169
Georg Brandlba83f822010-03-14 09:50:54 +00002170- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2171 element is temporarily replaced with an equivalent frozenset. But the
2172 eventual KeyError would always report the empty ``frozenset()`` as the missing
2173 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002193- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2194 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2195 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2196 of using the replace error handler in PyUnicode_DecodeUTF8().
2197
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002198- Issue #3739: The unicode-internal encoder now reports the number of characters

2200
Georg Brandlba83f822010-03-14 09:50:54 +00002201- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2202 allocator will be automatically disabled when running under Valgrind. This
2203 gives improved memory leak detection when running under Valgrind, while taking
2204 advantage of pymalloc at other times.

2275 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00002276 __main__.py file. This allows applications that run other Python scripts to
2277 support the same flexibility as the CPython command line itself.

3570
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003571- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3572 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3573 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3574 ``printf`` function, whereas PyString_FromFormat has an independent
3575 implementation and uses "%zd" on all platforms for size_t values.
3576 This makes a difference on win64, where ``printf`` needs "%Id" to display
3577 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003579- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3583 object; previously an int would be returned for small values. the __long__
3584 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003594 was correctly parsed but parsing of subsequent arguments failed.
3595
Vinay Sajip35e3b032008-09-01 14:33:59 +00003596- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003597 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3598 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3599 when given a tuple of classes as second argument, were looking up
3600 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3601 type object.

3698
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003699- Issue #2975: When compiling several extension modules with Visual Studio 2008
3700 from the same python interpreter, some environment variables would grow
3701 without limit.
3702
Benjamin Peterson37346b22008-08-23 20:27:43 +00003703- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

3719 wrapper for warnings.catch_warnings() that makes it easier to check
3720 that expected warning messages are being reported.
3721

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003740What's New in Python 2.6 beta 3?
3741================================
3742
Barry Warsaw07a4a382008-08-21 01:15:08 +00003743*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003744
3745Core and Builtins
3746-----------------
3747
Guido van Rossumf8402962008-08-20 15:01:50 +00003748- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3749 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3750 extensions do not automatically benefit from the class attribute
3751 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3752 to their tp_flags field if they care. This is a backwards
3753 compatibility feature; in 3.0, all types will use the cache by
3754 default.
3755
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003756- Keyword arguments can now follow starred arguments. (``f(a, *args,
3757 keyword=23)`` is now valid syntax.)
3758
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003759- ctypes function pointers that are COM methods have a boolean True
3760 value again.
3761
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003762- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3763 by denying s# to parse objects that have a releasebuffer procedure,
3764 and introducing s*.
3765
Georg Brandl1e13ea92008-08-11 09:07:59 +00003766- Issue #3537: Fix an assertion failure when an empty but presized dict
3767 object was stored in the freelist.
3768
Mark Dickinsonb6467572008-08-04 21:30:09 +00003769- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3770 ValueError consistently across platforms.
3771
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003772- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3773 (64bit Unix, for example), unichr() would truncate its argument and return
3774 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3775
Neal Norwitze7d8be82008-07-31 17:17:14 +00003776- Apply security patches from Apple.
3777
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003778- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3779 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3780
Antoine Pitrou92f82162008-07-25 22:22:08 +00003781- Issue #1819: function calls with several named parameters are now on
3782 average 35% faster (as measured by pybench).
3783
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003784- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3785 the python debugger steps into a class statement: the free variables (local
3786 variables defined in an outer scope) would be deleted from the outer scope.
3787
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003788- Issue #2620: Overflow checking when allocating or reallocating memory
3789 was not always being done properly in some python types and extension
3790 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3791 all been updated to perform better checks and places in the code that
3792 would previously leak memory on the error path when such an allocation
3793 failed have been fixed.
3794
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003795Library
3796-------
3797
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003798- Issue #3612: Added some missing basic types in ctypes.wintypes.
3799
Benjamin Petersone977ad42008-08-20 01:42:01 +00003800- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3801 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3802
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003803- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3804 version reported by these tools does not necessarily follow the python
3805 version numbering scheme, so the module is less strict when parsing it.
3806
Nick Coghlanf70385a2008-08-18 12:42:46 +00003807- Issue #2235: Added Py3k warnings for types which will become unhashable
3808 under the stricter __hash__ inheritance rules in 3.0. Several types
3809 which did not meet the rules for hash invariants and were already
3810 unhashable in 3.0 have now been explicitly flagged as unhashable in
3811 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3812 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3813
Brett Cannon88f801d2008-08-18 00:46:22 +00003814- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3815 imported into the module but exposed as part of the module's API.
3816
Brett Cannon7b96f072008-08-18 00:41:11 +00003817- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3818
Brett Cannon46225e72008-08-18 00:36:52 +00003819- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3820
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003821- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3822
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003823- Issue #3575: Incremental decoder's decode function now takes bytearray
3824 by using 's*' instead of 't#'.
3825
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003826- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003827 fails unicode conversion on 2nd parameter. (windows only)
3828
Georg Brandl222e2082010-08-01 22:27:39 +00003829- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003830 in a redirect.
3831
Brett Cannonabe423e2008-08-16 21:47:07 +00003832- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003833 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003834
Facundo Batistaeb90b782008-08-16 14:44:07 +00003835- Issue #2776: fixed small issue when handling an URL with double slash
3836 after a 302 response in the case of not going through a proxy.
3837
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003838- Issue #2676: in the email package, content-type parsing was hanging on
3839 pathological input because of quadratic or exponential behaviour of a
3840 regular expression.
3841
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003842- Issue #3476: binary buffered reading through the new "io" library is now
3843 thread-safe.
3844
Brett Cannonbf3157b2008-08-14 05:00:03 +00003845- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3846 since mimetools itself is deprecated. Because modules are cached, all
3847 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3848
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003849- Issue #3134: shutil referenced undefined WindowsError symbol.
3850
Robert Schuppenies14646332008-08-10 11:01:53 +00003851- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3852 menu entries were not deleted.
3853
Brett Cannon83e81842008-08-09 23:30:55 +00003854- Copied the implementation of reduce() to _functools.reduce() to have a
3855 version that did not raise a DeprecationWarning under -3.
3856
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003857- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3858 a MemoryError rather than silently stop the iteration.
3859
Guido van Rossum59ce9012008-08-09 14:55:34 +00003860- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3861 to _sre.compile() will now be rejected. This should not affect anybody
3862 since the re.compile() function never generates invalid re-bytecode.
3863
Skip Montanaroa032bf42008-08-08 22:52:51 +00003864- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3865 upon first access it can be automatically initialized from the csv file if
3866 it wasn't initialized during instantiation.
3867
Brett Cannon3aa2a492008-08-06 22:28:09 +00003868- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3869 the reload() built-in has been removed.
3870
Brett Cannon7e30b672008-08-04 21:52:25 +00003871- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003872 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3880 raised an AttributeError.
3881
Benjamin Peterson01a24322008-07-28 23:35:27 +00003882- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003883 asking for a specific length. This problem only affected files opened
3884 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003885
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003886- Issue #3449: Update decimal module to use most recent specification
3887 (v. 1.68) and tests (v. 2.58) from IBM.
3888
Georg Brandl222e2082010-08-01 22:27:39 +00003889- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

3908
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003909- Issue #3394: zipfile.writestr sets external attributes when passed a
3910 file name rather than a ZipInfo instance, so files are extracted with
3911 mode 0600 rather than 000 under Unix.
3912
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003913- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3914 argument in python 2.5, this broke code that subclassed Popen to include its
3915 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003925- Issue #2235: the C API function PyObject_HashNotImplemented and its
3926 interaction with the tp_hash slot (added in 2.6b2) are now documented
3927
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003928- Issue #643841: The language reference now provides more detailed
3929 coverage of the lookup process for special methods. The disclaimers
3930 regarding lack of coverage of new-style classes have also been
3931 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003939Core and Builtins
3940-----------------
3941
Georg Brandl3e483f62008-07-16 22:57:41 +00003942- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3943 its methods now allow for items objects that can be converted to
3944 an integer using operator.index().
3945
Mark Dickinson64b7e502008-07-16 09:40:03 +00003946- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3947 produced a ValueError instead of giving the correct float.
3948
Eric Smitha5fa5a22008-07-16 00:11:49 +00003949- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3950 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3951
Mark Dickinson7103aa42008-07-15 19:08:33 +00003952- Issue #3008: the float type has a new instance method 'float.hex'
3953 and a new class method 'float.fromhex' to convert floating-point
3954 numbers to and from hexadecimal strings, respectively.
3955
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003956- Issue #2235: __hash__ is once again inherited by default. To allow
3957 collections.Hashable to remain meaningful in the presence of the
3958 default hash implementation (object.__hash__), it is now possible
3959 to explicit block inheritance of hash by setting __hash__=None at
3960 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3961 level.
3962
Nick Coghlanb028f502008-07-13 14:52:36 +00003963- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3964 the parent module cannot be found while performing an absolute import.
3965 This means that an incorrectly defined __package__ attribute will
3966 now only prevent relative imports in that module rather than causing
3967 all imports from that module to fail.
3968
Nick Coghlan14ff9942008-07-08 14:21:42 +00003969- Issue #2517: Allow unicode messages in Exceptions again by correctly
3970 bypassing the instance dictionary when looking up __unicode__ on
3971 new-style classes.

3985 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00004440 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004441
4442 This is controlled by the configure argument ``--with-universal-archs``:
4443

4445
4446 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4447
4448 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4449

4489 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- Issue #1631171: Re-implement the 'warnings' module in C (the
4503 original Python code has been kept as backup). This will allow for
4504 using the 'warning's machinery in such places as the parser where
4505 use of pure Python code is not possible. Both the ``showarning()``
4506 and ``formatwarning()`` gain an optional 'line' argument which is
4507 not called by default for backwards-compatibility reasons. Setting
4508 ``warnings.showwarning()`` to an implementation that lacks support
4509 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Issue #2550: The approach used by client/server code for obtaining
4573 ports to listen on in network-oriented tests has been refined in an
4574 effort to facilitate running multiple instances of the entire
4575 regression test suite in parallel without issue.
4576 test_support.bind_port() has been fixed such that it will always
4577 return a unique port -- which wasn't always the case with the
4578 previous implementation, especially if socket options had been set
4579 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4580 new implementation of bind_port() will actually raise an exception
4581 if it is passed an AF_INET/SOCK_STREAM socket with either the
4582 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4583 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4584 the socket it's been passed. This currently only applies to
4585 Windows. This option prevents any other sockets from binding to the
4586 host/port we've bound to, thus removing the possibility of the
4587 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4588 when a second SOCK_STREAM socket binds and accepts to a host/port
4589 that's already been bound by another socket. The optional preferred
4590 port parameter to bind_port() has been removed. Under no
4591 circumstances should tests be hard coding ports!
4592
4593 test_support.find_unused_port() has also been introduced, which will
4594 pass a temporary socket object to bind_port() in order to obtain an
4595 unused port. The temporary socket object is then closed and
4596 deleted, and the port is returned. This method should only be used
4597 for obtaining an unused port in order to pass to an external program
4598 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4599 a parameter to a server-oriented class that doesn't give you direct
4600 access to the underlying socket used.
4601
4602 Finally, test_support.HOST has been introduced, which should be used
4603 for the host argument of any relevant socket calls (i.e. bind and
4604 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004605
4606 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004607 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004608 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4609 test_asynchat and test_socket_ssl.
4610
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611 It is now possible for multiple instances of the regression test
4612 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00004795- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00004796 optional: it defaults to the traceback of the exception that is
4797 currently being handled (is mandatory to be in the middle of an
4798 exception, otherwise it raises ValueError).

4815
Thomas Heller78b8f442008-03-05 14:53:39 +00004816- The bundled libffi copy is now in sync with the recently released
4817 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004818 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4819 files are used. On all linux systems the --with-system-ffi
4820 configure option defaults to "yes".

Facundo Batistafc2d0102008-02-23 12:01:13 +00004890
Eric Smitha73fbe72008-02-23 03:09:44 +00004891- Added the future_builtins module, which contains hex() and oct().
4892 These are the PEP 3127 version of these functions, designed to be
4893 compatible with the hex() and oct() builtins from Python 3.0. They
4894 differ slightly in their output formats from the existing, unchanged
4895 Python 2.6 builtins. The expected usage of the future_builtins
4896 module is:
4897 from future_builtins import hex, oct
4898
Eric Smith7ef40bf2008-02-20 23:34:22 +00004899- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4900 exponents for exponents with absolute value < 100. Follows C99
4901 standard. This is a change on Windows, which would use 3 digits.
4902 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4903 so that any alterations it does to the resulting string will be
4904 available in stringlib/formatter.h (for float.__format__).
4905
Eric Smith5a3c1352008-02-19 13:21:56 +00004906- Implemented PEP 3101, Advanced String Formatting. This adds a new
4907 builtin format(); a format() method for str and unicode; a
4908 __format__() method to object, str, unicode, int, long, float, and
4909 datetime; the class string.Formatter; and the C API
4910 PyObject_Format().
4911
Georg Brandl3ee81df2008-05-17 18:14:43 +00004912- Fixed several potential crashes, all caused by specially crafted
4913 __del__ methods exploiting objects in temporarily inconsistent
4914 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004915
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004916- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917 prevent a possible crash: an Abstract Base Class would try to access
4918 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004919
Georg Brandl3ee81df2008-05-17 18:14:43 +00004920- Fixed repr() and str() of complex numbers with infinity or nan as
4921 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- Clear all free lists during a gc.collect() of the highest generation
4924 in order to allow pymalloc to free more arenas. Python may give back
4925 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #2045: Fix an infinite recursion triggered when printing a
4928 subclass of collections.defaultdict, if its default_factory is set
4929 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004930
Christian Heimesf75dbef2008-02-08 00:11:31 +00004931- Fixed a minor memory leak in dictobject.c. The content of the free
4932 list was not freed on interpreter shutdown.
4933
Georg Brandl21e99f42010-03-07 15:23:59 +00004934- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004935 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004936
Georg Brandl3ee81df2008-05-17 18:14:43 +00004937- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4938 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004939 to compact the internal free lists of pre-allocted ints and floats.
4940
Georg Brandl3ee81df2008-05-17 18:14:43 +00004941- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4942 calls. Python expected the return type int but the fork familie
4943 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004944
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4946 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004947
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4949 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004954- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4955 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004956
Georg Brandl3ee81df2008-05-17 18:14:43 +00004957- Patch #1473257: generator objects gain a gi_code attribute. This is
4958 the same object as the func_code attribute of the function that
4959 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004960
Georg Brandl3ee81df2008-05-17 18:14:43 +00004961- Issue #1920: "while 0" statements were completely removed by the
4962 compiler, even in the presence of an "else" clause, which is
4963 supposed to be run when the condition is false. Now the compiler
4964 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004965
Guido van Rossumeead05f2008-01-24 18:21:02 +00004966- A few crashers fixed: weakref_in_del.py (issue #1377858);
4967 loosing_dict_ref.py (issue #1303614, test67.py);
4968 borrowed_ref_[34].py (not in tracker).
4969
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004970- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004971 suppressed while an extension is loaded by calling SetErrorMode in
4972 dynload_win.c. The error is still reported properly.
4973
Georg Brandl3ee81df2008-05-17 18:14:43 +00004974- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004975 several extension methods and modules do not work without unicode
4976 support.
4977
Georg Brandl26543b12008-01-21 18:36:51 +00004978- Issue #1882: when compiling code from a string, encoding cookies in the
4979 second line of code were not always recognized correctly.
4980
Georg Brandl14404b62008-01-19 19:27:05 +00004981- Issue #1679: "0x" was taken as a valid integer literal.
4982
Georg Brandl6caad7d2008-01-26 14:19:22 +00004983- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004984 added.
4985
Christian Heimesc94e2b52008-01-14 04:13:37 +00004986- sys.float_info / PyFloat_GetInfo: The floating point information
4987 object was converted from a dict to a specialized structseq object.
4988
Georg Brandl3ee81df2008-05-17 18:14:43 +00004989- Patch #1816: Added sys.flags structseq. It exposes the status of
4990 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Objects/structseq.c: Implemented new structseq representation. The
4993 patch makes structseqs (e.g. the return value of os.stat) more
4994 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004995
Georg Brandl3ee81df2008-05-17 18:14:43 +00004996- Patch #1700288: added a type attribute cache that caches method

5005 envvar and sys.dont_write_bytecode attribute. All these can be set
5006 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005007
Georg Brandl3ee81df2008-05-17 18:14:43 +00005008- Improve some exception messages when Windows fails to load an
5009 extension module. Now we get for example '%1 is not a valid Win32
5010 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005018 and INF. float("nan"), float("inf") and float("-inf") now work on
5019 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005020
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- Compiler now generates simpler and faster code for dictionary
5022 literals. The oparg for BUILD_MAP now indicates an estimated
5023 dictionary size. There is a new opcode, STORE_MAP, for adding
5024 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005053- Patch #1739468: Directories and zipfiles containing a __main__.py
5054 file can now be directly executed by passing their name to the
5055 interpreter. The directory/zipfile is automatically inserted as the
5056 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005057
Georg Brandl3ee81df2008-05-17 18:14:43 +00005058- Issue #1265: Fix a problem with sys.settrace, if the tracing
5059 function uses a generator expression when at the same time the
5060 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005061
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005062- sets and frozensets now have an isdisjoint() method.
5063

5067
Georg Brandl21e99f42010-03-07 15:23:59 +00005068- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5070 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005071
Georg Brandl3ee81df2008-05-17 18:14:43 +00005072- Issue #1686386: Tuple's tp_repr did not take into account the
5073 possibility of having a self-referential tuple, which is possible
5074 from C code. Nor did object's tp_str consider that a type's tp_str
5075 could do something that could lead to an inifinite recursion.
5076 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5077 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005078
Georg Brandl3ee81df2008-05-17 18:14:43 +00005079- Issue #1164: It was possible to trigger deadlock when using the
5080 'print' statement to write to a file since the GIL was not released
5081 as needed. Now PyObject_Print() does the right thing along with
5082 various tp_print implementations of the built-in types and those in
5083 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005084
Georg Brandl3ee81df2008-05-17 18:14:43 +00005085- Issue #1147: Exceptions were directly allowing string exceptions in
5086 their throw() method even though string exceptions no longer
5087 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005088
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089- Issue #1096: Prevent a segfault from getting the repr of a very
5090 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005091
Brett Cannon1e534b52007-09-07 04:18:30 +00005092- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005093 PyObject_Call() never calling back out to Python code to trigger
5094 recursion depth updates/checks. Required the creation of a static
5095 RuntimeError instance in case normalizing an exception put the
5096 recursion check value past its limit. Fixes crashers
5097 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005112- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113 __*__ attributes. (Some already existed, e.g., __doc__ and
5114 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005115
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005116- Add -3 option to the interpreter to warn about features that are
5117 deprecated and will be changed/removed in Python 3.0.
5118
Georg Brandl2134e752007-05-21 20:34:16 +00005119- Patch #1686487: you can now pass any mapping after '**' in function
5120 calls.
5121
Collin Winter62903052007-05-18 23:11:24 +00005122- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005123 "except E as target:". This is to provide forwards compatibility
5124 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005125
Brett Cannon229cee22007-05-05 01:34:02 +00005126- Deprecate BaseException.message as per PEP 352.
5127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005129 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005130
Vinay Sajip8549ce32007-05-06 17:53:37 +00005131- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005132 setting a plain string, ie don't expand to single letter identifiers.
5133
Raymond Hettinger13936692007-04-11 18:40:58 +00005134- Request #1191699: Slices can now be pickled.
5135
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005136- Request #1193128: str.translate() now allows a None argument for
5137 translations that only remove characters without re-mapping the
5138 remaining characters.
5139
Georg Brandl5cb76c12007-03-21 09:00:39 +00005140- Patch #1682205: a TypeError while unpacking an iterable is no longer
5141 masked by a generic one with the message "unpack non-sequence".
5142
Neal Norwitzaa754b72007-03-21 06:39:48 +00005143- Remove unused file Python/fmod.c.
5144
Guido van Rossum143b5642007-03-23 04:58:42 +00005145- Bug #1683368: The object.__init__() and object.__new__() methods are
5146 now stricter in rejecting excess arguments. The only time when
5147 either allows excess arguments is when it is not overridden and the
5148 other one is. For backwards compatibility, when both are
5149 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005150 warning later). Also, type.__init__() insists on the same signature
5151 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5154 object to complex using its __complex__() method before falling back
5155 to the __float__() method. Therefore, the functions in the cmath
5156 module now can operate on objects that define a __complex__()
5157 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005158
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159- Patch #1623563: allow __class__ assignment for classes with
5160 __slots__. The old and the new class are still required to have the
5161 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005162
Georg Brandl3ee81df2008-05-17 18:14:43 +00005163- Patch #1642547: Fix an error/crash when encountering syntax errors

5167 ``object.__reduce_ex__()`` is called with an object that is faking
5168 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- Patch #1680015: Don't modify __slots__ tuple if it contains an

5174
Georg Brandl7b9c5552007-03-12 14:30:05 +00005175- Bug #1678647: write a newline after printing an exception in any
5176 case, even when converting the value to a string failed.
5177
Georg Brandl871f1bc2007-03-12 13:17:36 +00005178- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005179 its argument, if it exists. If not, it will work like before. This
5180 allows customizing the output of dir() in the presence of a
5181 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005182
Collin Winter276887b2007-03-12 16:11:39 +00005183- Patch #922167: Python no longer segfaults when faced with infinitely
5184 self-recursive reload() calls (as reported by bug #742342).
5185
Georg Brandl3ee81df2008-05-17 18:14:43 +00005186- Patch #1675981: remove unreachable code from ``type.__new__()``
5187 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005189- Patch #1491866: change the complex() constructor to allow
5190 parthensized forms. This means complex(repr(x)) now works instead of
5191 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005192
Georg Brandlaa2321b2007-03-07 00:40:28 +00005193- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194 makes the filenames the warning module prints much more sensible
5195 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005196
Georg Brandl49aafc92007-03-07 00:34:46 +00005197- Variant of patch #697613: don't exit the interpreter on a SystemExit
5198 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199 variable is given, but break into the interactive interpreter just
5200 like on other exceptions or normal program exit.

5206 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005207
Georg Brandl0fca97a2007-03-05 22:28:08 +00005208- Patch #1674228: when assigning a slice (old-style), check for the
5209 sq_ass_slice instead of the sq_slice slot.
5210
Georg Brandl3ee81df2008-05-17 18:14:43 +00005211- When printing an unraisable error, don't print exceptions. before
5212 the name. This duplicates the behavior whening normally printing
5213 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005215- Bug #1653736: Properly discard third argument to

Guido van Rossum8bc09652008-02-21 18:18:37 +00005355- Removed uses of dict.has_key() from distutils, and uses of

5779
Georg Brandl92a6bae2007-03-13 17:43:32 +00005780- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781 are set for invalid interpolation sequences that would lead to

5838 TestCase and TestSuite subclasses (not instances) are no longer
5839 accepted in TestSuite.addTest(). This should cause no
5840 incompatibility since it never made sense with ordinary subclasses
5841 -- the failure just occurred later, with a more cumbersome
5842 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006123- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6124 with RFC 3207 and forgets any knowledge obtained from the server not
6125 obtained from the TLS negotiation itself. Patch contributed by Bill
6126 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006127
Georg Brandl3ee81df2008-05-17 18:14:43 +00006128- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006129 that the SMTP.starttls() caller no longer needs to call ehlo()
6130 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006131 does not claim to support starttls. Adds the
6132 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00006176 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006187- itertools.chain() now has an alternate constructor,

6213 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6214 silently miscode subclasses of those types. Now, it raises a
6215 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006216

Georg Brandl3ee81df2008-05-17 18:14:43 +00006231 time so that opening a database previously created with the DB_DUP
6232 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6233 opens. Specifically: dictionary assignment to a DB object will
6234 replace all values for a given key when the database allows
6235 duplicate values. DB users should use DB.put(k, v) when they want
6236 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006237

6241
Georg Brandl3ee81df2008-05-17 18:14:43 +00006242- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
6243 characters with ASCII value less than 32. Also, it correctly quotes
6244 dots only if they occur on a single line, as opposed to the previous

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006515- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516 periodic threadstate and signal checking in tight loops. By
6517 default, this option is turned-off. It should only be enabled in
6518 debugged, performance critical applications.

6569-----
6570
Georg Brandl3ee81df2008-05-17 18:14:43 +00006571- Unified naming convention for free lists and their limits. All free
6572 lists in Object/ are named ``free_list``, the counter ``numfree``
6573 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6574 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006575
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6577 to ``PyTuple_SetItem``, it can be used to populate a brand new
6578 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00006579

6590
Georg Brandl3ee81df2008-05-17 18:14:43 +00006591- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6592 of w# format code incorrectly truncated the length to an int, even
6593 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6594 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006595
Georg Brandl3ee81df2008-05-17 18:14:43 +00006596- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6614- Fix some leftovers from the conversion from int to Py_ssize_t
6615 (relevant to strings and sequences of more than 2**31 items).
6616
6617- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6618 outside of pystate.c and should not be necessary.
6619
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6621 absolute imports. In earlier versions they might have used relative
6622 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006623
Georg Brandl3ee81df2008-05-17 18:14:43 +00006624- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6625 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006626
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006652- Removed the macfs module. It had been deprecated since Python 2.5.
6653 This lead to the deprecation of macostools.touched() as it relied
6654 solely on macfs and was a no-op under OS X.
