104
Antoine Pitrou2c7d6852010-09-23 19:55:24 +0000105- Issue #9928: Properly initialize the types exported by the bz2 module.
106
Antoine Pitrou6391b342010-09-14 18:48:19 +0000107- Issue #9854: The default read() implementation in io.RawIOBase now
108 handles non-blocking readinto() returning None correctly.
109
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000110- Issue #9729: Fix the signature of SSLSocket.recvfrom() and

112 fix various SSLSocket methods to raise socket.error rather than an
113 unhelpful TypeError when called on an unconnected socket. Original patch
114 by Andrew Bennetts.
115
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000116- Issue #9826: OrderedDict.__repr__ can now handle self-referential

125 This prevents user-created self-referencing ordered dictionaries from
126 becoming permanently uncollectable GC garbage. The downside is that
127 removing __del__ means that the internal doubly-linked list has to wait for
128 GC collection rather than freeing memory immediately when the refcnt drops
129 to zero.
130
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000131- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

136 would swallow the exception and raise a new one, making it impossible
137 to fetch the original errno, or to filter timeout errors. Now the
138 original error is re-raised.
139
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000140- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
141 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
142 be updated back after the system call. Original patch by Brian Brazil.
143
Antoine Pitroudca9de92010-09-04 17:52:26 +0000144- Issue #1100562: Fix deep-copying of objects derived from the list and
145 dict types. Patch by Michele Orrù and Björn Lindqvist.
146
Fred Drakea1e627d2010-09-03 03:55:50 +0000147- Issue #7005: Fixed output of None values for RawConfigParser.write and
148 ConfigParser.write.
149
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000150- Issue #808164: Fixed socket.close to avoid references to globals, to
151 avoid issues when socket.close is called from a __del__ method.
152
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000153- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

157 character years even if the message contains RFC822 two character years.
158
Daniel Stutzbach91287322010-08-24 21:09:30 +0000159- Issue #8750: Fixed MutableSet's methods to correctly handle
160 reflexive operations, namely x -= x and x ^= x.
161
Victor Stinnercaafd772010-09-08 10:51:01 +0000162- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000163 error handling when accepting a new connection.

171 module now correctly return a set. (Patch by Eli Bendersky.)
172
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000173- Issue #9617: Signals received during a low-level write operation aren't
174 ignored by the buffered IO layer anymore.
175
Benjamin Peterson52c36052010-08-21 03:03:22 +0000176- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
177 are not held onto after they are deleted elsewhere.
178
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000179- Issue #9626: the view methods for collections.OrderedDict() were returning
180 the unordered versions inherited from dict. Those methods are now
181 overridden to provide ordered views.
182
Éric Araujo0389ae62010-08-14 03:07:46 +0000183- Issue #8688: MANIFEST files created by distutils now include a magic

215 This is how it is supposed to work, wget and curl do the same. Previous
216 behavior was wrong.

580 of the number of bytes specified by the start byte.
581 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000939 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

962-----------------
963
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000964- Issue #7301: Add environment variable $PYTHONWARNINGS.
965
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000966- Issue #8329: Don't return the same lists from select.select when no fds are
967 changed.
968
Georg Brandlfee0f442010-05-22 21:26:21 +0000969- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000970 on 64-bit machines. The shift count for either left or right shift is
971 permitted to be up to sys.maxsize.
972
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000973- Ensure that tokenization of identifiers is not affected by locale.

978
Georg Brandlfee0f442010-05-22 21:26:21 +0000979- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
980 with a non-empty format string. This is an effort to future-proof user
981 code. If a derived class does not currently implement __format__ but later
982 adds its own __format__, it would most likely break user code that had
983 supplied a format string. This will be changed to a DeprecationWaring in
984 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000985
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000986- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +00001011- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001012 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

1016
Georg Brandlfee0f442010-05-22 21:26:21 +00001017- Issue #8257: The Decimal construct now accepts a float instance directly,
1018 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001019
1020 >>> Decimal(1.1)

1022
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001023- collections.Counter() now supports a subtract() method.
1024
Georg Brandlfee0f442010-05-22 21:26:21 +00001025- The functools module now has a total_ordering() class decorator to simplify
1026 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001027
Georg Brandlfee0f442010-05-22 21:26:21 +00001028- The functools module also adds cmp_to_key() as a tool to transition old-style
1029 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001030

Georg Brandlfee0f442010-05-22 21:26:21 +00001034- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1035 InvalidOperation instead of returning False. (Comparisons involving a quiet
1036 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1037 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001038
Georg Brandlfee0f442010-05-22 21:26:21 +00001039- Issue #2531: Comparison operations between floats and Decimal instances now
1040 return a result based on the numeric values of the operands; previously they
1041 returned an arbitrary result based on the relative ordering of id(float) and
1042 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001043
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001044- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001045 argument `-` which tells it to read files to compile from stdin. Each line is
1046 read on demand and the named file is compiled immediately. (Original patch by
1047 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001052- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1053 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001054 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001055
Georg Brandlfee0f442010-05-22 21:26:21 +00001056- Comparisons using one of <, <=, >, >= between a complex instance and a
1057 Fractions instance now raise TypeError instead of returning True/False. This
1058 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1059 <=> complex, and complex <=> complex comparisons.

1169 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001466 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001473 file position when calling `truncate()`. It would previously change the file
1474 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001475 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1476

1478 class used to represent files stored inside an archive. The new
1479 implementation is significantly faster and can be wrapped in a
1480 ``io.BufferedReader`` object for more speedups. It also solves an issue
1481 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1482 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001492- Issue #7748: Since unicode values are supported for some metadata options in
1493 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1494 encoded string for them. This ensures that the upload and register commands
1495 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001766- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1767 decimal string that's guaranteed to round back to x under correct rounding
1768 (with round-half-to-even rounding mode). Previously it gave a string based on
1769 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1770 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1771 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001772
Georg Brandlba83f822010-03-14 09:50:54 +00001773- Issue #7117: On almost all platforms: float-to-string and string-to-float
1774 conversions within Python are now correctly rounded. Places these conversions
1775 occur include: str for floats and complex numbers; the float and complex
1776 constructors; old-style and new-style numeric formatting; serialization and
1777 deserialization of floats and complex numbers using marshal, pickle and json;
1778 parsing of float and imaginary literals in Python code; Decimal-to-float
1779 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001780
Georg Brandlba83f822010-03-14 09:50:54 +00001781 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1782 providing correctly-rounded strtod and dtoa C functions. This code is
1783 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1784 the C compiler. There may be a small number of platforms on which correct
1785 operation of this code cannot be guaranteed, so the code is not used: notably,
1786 this applies to platforms where the C double format is not IEEE 754 binary64,
1787 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1788 and Python's configure script is unable to determine how to change the FPU
1789 precision. On these platforms conversions use the platform strtod and dtoa,
1790 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001792- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1793 uses the correctly-rounded string <-> float conversions described above (when
1794 available), and so produces correctly rounded results that will display nicely
1795 under the float repr. There are two related small changes: (1) round now
1796 accepts any class with an ``__index__()`` method for its second argument (but
1797 no longer accepts floats for the second argument), and (2) an excessively
1798 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1799 raises an exception.

1943 (2) parsing of strings representing infinities and nans was locale aware; and
1944 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001946- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1947 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1948 but with at least one decimal point and with a default precision
1949 of 12. Previously, the behavior the same but with a default precision of 6.
1950 This more closely matches ``str()``, and reduces surprises when adding
1951 alignment flags to the empty presentation type. This also affects the new
1952 complex.__format__ in the same way.
1953
1954- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandl29c6a282009-04-05 20:23:13 +00002061- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002062 were suppressing all exceptions. These include list(), filter(), map(),

2064
Benjamin Peterson596d3062009-01-19 15:42:23 +00002065- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002092- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2093 existing .py counterpart, override the co_filename attributes of all code
2094 objects if the original filename is obsolete (which can happen if the file has

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002140- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2143
Georg Brandlba83f822010-03-14 09:50:54 +00002144- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2149
Georg Brandlba83f822010-03-14 09:50:54 +00002150- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2151 file objects with closefd=False. The file descriptor is still kept open but
2152 the file object behaves like a closed file. The ``FileIO`` object also got a
2153 new readonly attribute ``closefd``.

2172
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002173- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002176- On windows, ``os.chdir()`` given unicode was not working if
2177 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2178 this code path is really executed because I cannot move to such directory on
2179 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002181- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2182 element is temporarily replaced with an equivalent frozenset. But the
2183 eventual KeyError would always report the empty ``frozenset()`` as the missing
2184 key. Now it correctly refers to the initial element.

2203
Walter Dörwalded960ac2009-05-03 22:36:33 +00002204- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2205 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2206 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2207 of using the replace error handler in PyUnicode_DecodeUTF8().
2208
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002209- Issue #3739: The unicode-internal encoder now reports the number of characters

2211
Georg Brandlba83f822010-03-14 09:50:54 +00002212- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2213 allocator will be automatically disabled when running under Valgrind. This
2214 gives improved memory leak detection when running under Valgrind, while taking
2215 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00002287 __main__.py file. This allows applications that run other Python scripts to
2288 support the same flexibility as the CPython command line itself.

3581
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003582- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3583 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3584 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3585 ``printf`` function, whereas PyString_FromFormat has an independent
3586 implementation and uses "%zd" on all platforms for size_t values.
3587 This makes a difference on win64, where ``printf`` needs "%Id" to display
3588 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003590- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3594 object; previously an int would be returned for small values. the __long__
3595 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00003607- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003608 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3609 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3610 when given a tuple of classes as second argument, were looking up
3611 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3612 type object.

3709
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003710- Issue #2975: When compiling several extension modules with Visual Studio 2008
3711 from the same python interpreter, some environment variables would grow
3712 without limit.
3713
Benjamin Peterson37346b22008-08-23 20:27:43 +00003714- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003751What's New in Python 2.6 beta 3?
3752================================
3753
Barry Warsaw07a4a382008-08-21 01:15:08 +00003754*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003755
3756Core and Builtins
3757-----------------
3758
Guido van Rossumf8402962008-08-20 15:01:50 +00003759- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3760 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3761 extensions do not automatically benefit from the class attribute
3762 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3763 to their tp_flags field if they care. This is a backwards
3764 compatibility feature; in 3.0, all types will use the cache by
3765 default.
3766
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003767- Keyword arguments can now follow starred arguments. (``f(a, *args,
3768 keyword=23)`` is now valid syntax.)
3769
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003770- ctypes function pointers that are COM methods have a boolean True
3771 value again.
3772
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003773- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3774 by denying s# to parse objects that have a releasebuffer procedure,
3775 and introducing s*.
3776
Georg Brandl1e13ea92008-08-11 09:07:59 +00003777- Issue #3537: Fix an assertion failure when an empty but presized dict
3778 object was stored in the freelist.
3779
Mark Dickinsonb6467572008-08-04 21:30:09 +00003780- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3781 ValueError consistently across platforms.
3782
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003783- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3784 (64bit Unix, for example), unichr() would truncate its argument and return
3785 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3786
Neal Norwitze7d8be82008-07-31 17:17:14 +00003787- Apply security patches from Apple.
3788
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003789- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3790 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3791
Antoine Pitrou92f82162008-07-25 22:22:08 +00003792- Issue #1819: function calls with several named parameters are now on
3793 average 35% faster (as measured by pybench).
3794
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003795- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3796 the python debugger steps into a class statement: the free variables (local
3797 variables defined in an outer scope) would be deleted from the outer scope.
3798
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003799- Issue #2620: Overflow checking when allocating or reallocating memory
3800 was not always being done properly in some python types and extension
3801 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3802 all been updated to perform better checks and places in the code that
3803 would previously leak memory on the error path when such an allocation
3804 failed have been fixed.
3805
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003806Library
3807-------
3808
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003809- Issue #3612: Added some missing basic types in ctypes.wintypes.
3810
Benjamin Petersone977ad42008-08-20 01:42:01 +00003811- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3812 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3813
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003814- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3815 version reported by these tools does not necessarily follow the python
3816 version numbering scheme, so the module is less strict when parsing it.
3817
Nick Coghlanf70385a2008-08-18 12:42:46 +00003818- Issue #2235: Added Py3k warnings for types which will become unhashable
3819 under the stricter __hash__ inheritance rules in 3.0. Several types
3820 which did not meet the rules for hash invariants and were already
3821 unhashable in 3.0 have now been explicitly flagged as unhashable in
3822 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3823 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3824
Brett Cannon88f801d2008-08-18 00:46:22 +00003825- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3826 imported into the module but exposed as part of the module's API.
3827
Brett Cannon7b96f072008-08-18 00:41:11 +00003828- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3829
Brett Cannon46225e72008-08-18 00:36:52 +00003830- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003832- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3833
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003834- Issue #3575: Incremental decoder's decode function now takes bytearray
3835 by using 's*' instead of 't#'.
3836
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003837- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003838 fails unicode conversion on 2nd parameter. (windows only)
3839
Georg Brandl222e2082010-08-01 22:27:39 +00003840- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003841 in a redirect.
3842
Brett Cannonabe423e2008-08-16 21:47:07 +00003843- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003844 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003845
Facundo Batistaeb90b782008-08-16 14:44:07 +00003846- Issue #2776: fixed small issue when handling an URL with double slash
3847 after a 302 response in the case of not going through a proxy.
3848
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003849- Issue #2676: in the email package, content-type parsing was hanging on
3850 pathological input because of quadratic or exponential behaviour of a
3851 regular expression.
3852
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003853- Issue #3476: binary buffered reading through the new "io" library is now
3854 thread-safe.
3855
Brett Cannonbf3157b2008-08-14 05:00:03 +00003856- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3857 since mimetools itself is deprecated. Because modules are cached, all
3858 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3859
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003860- Issue #3134: shutil referenced undefined WindowsError symbol.
3861
Robert Schuppenies14646332008-08-10 11:01:53 +00003862- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3863 menu entries were not deleted.
3864
Brett Cannon83e81842008-08-09 23:30:55 +00003865- Copied the implementation of reduce() to _functools.reduce() to have a
3866 version that did not raise a DeprecationWarning under -3.
3867
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003868- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3869 a MemoryError rather than silently stop the iteration.
3870
Guido van Rossum59ce9012008-08-09 14:55:34 +00003871- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3872 to _sre.compile() will now be rejected. This should not affect anybody
3873 since the re.compile() function never generates invalid re-bytecode.
3874
Skip Montanaroa032bf42008-08-08 22:52:51 +00003875- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3876 upon first access it can be automatically initialized from the csv file if
3877 it wasn't initialized during instantiation.
3878
Brett Cannon3aa2a492008-08-06 22:28:09 +00003879- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3880 the reload() built-in has been removed.
3881
Brett Cannon7e30b672008-08-04 21:52:25 +00003882- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003883 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3891 raised an AttributeError.
3892
Benjamin Peterson01a24322008-07-28 23:35:27 +00003893- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003894 asking for a specific length. This problem only affected files opened
3895 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003896
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003897- Issue #3449: Update decimal module to use most recent specification
3898 (v. 1.68) and tests (v. 2.58) from IBM.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003920- Issue #3394: zipfile.writestr sets external attributes when passed a
3921 file name rather than a ZipInfo instance, so files are extracted with
3922 mode 0600 rather than 000 under Unix.
3923
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003924- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3925 argument in python 2.5, this broke code that subclassed Popen to include its
3926 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3937 interaction with the tp_hash slot (added in 2.6b2) are now documented
3938
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003939- Issue #643841: The language reference now provides more detailed
3940 coverage of the lookup process for special methods. The disclaimers
3941 regarding lack of coverage of new-style classes have also been
3942 removed, since the coverage is now fairly reasonable.

3947
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003948*Release date: 17-Jul-2008*
3949
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003950Core and Builtins
3951-----------------
3952
Georg Brandl3e483f62008-07-16 22:57:41 +00003953- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3954 its methods now allow for items objects that can be converted to
3955 an integer using operator.index().
3956
Mark Dickinson64b7e502008-07-16 09:40:03 +00003957- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3958 produced a ValueError instead of giving the correct float.
3959
Eric Smitha5fa5a22008-07-16 00:11:49 +00003960- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3961 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3962
Mark Dickinson7103aa42008-07-15 19:08:33 +00003963- Issue #3008: the float type has a new instance method 'float.hex'
3964 and a new class method 'float.fromhex' to convert floating-point
3965 numbers to and from hexadecimal strings, respectively.
3966
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003967- Issue #2235: __hash__ is once again inherited by default. To allow
3968 collections.Hashable to remain meaningful in the presence of the
3969 default hash implementation (object.__hash__), it is now possible
3970 to explicit block inheritance of hash by setting __hash__=None at
3971 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3972 level.
3973
Nick Coghlanb028f502008-07-13 14:52:36 +00003974- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3975 the parent module cannot be found while performing an absolute import.
3976 This means that an incorrectly defined __package__ attribute will
3977 now only prevent relative imports in that module rather than causing

Georg Brandl5cc774e2008-06-11 20:28:06 +00004451 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004452
4453 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00004513- Issue #1631171: Re-implement the 'warnings' module in C (the
4514 original Python code has been kept as backup). This will allow for
4515 using the 'warning's machinery in such places as the parser where
4516 use of pure Python code is not possible. Both the ``showarning()``
4517 and ``formatwarning()`` gain an optional 'line' argument which is
4518 not called by default for backwards-compatibility reasons. Setting
4519 ``warnings.showwarning()`` to an implementation that lacks support
4520 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004583- Issue #2550: The approach used by client/server code for obtaining
4584 ports to listen on in network-oriented tests has been refined in an
4585 effort to facilitate running multiple instances of the entire
4586 regression test suite in parallel without issue.
4587 test_support.bind_port() has been fixed such that it will always
4588 return a unique port -- which wasn't always the case with the
4589 previous implementation, especially if socket options had been set
4590 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4591 new implementation of bind_port() will actually raise an exception
4592 if it is passed an AF_INET/SOCK_STREAM socket with either the
4593 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4594 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4595 the socket it's been passed. This currently only applies to
4596 Windows. This option prevents any other sockets from binding to the
4597 host/port we've bound to, thus removing the possibility of the
4598 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4599 when a second SOCK_STREAM socket binds and accepts to a host/port
4600 that's already been bound by another socket. The optional preferred
4601 port parameter to bind_port() has been removed. Under no
4602 circumstances should tests be hard coding ports!
4603
4604 test_support.find_unused_port() has also been introduced, which will
4605 pass a temporary socket object to bind_port() in order to obtain an
4606 unused port. The temporary socket object is then closed and
4607 deleted, and the port is returned. This method should only be used
4608 for obtaining an unused port in order to pass to an external program
4609 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4610 a parameter to a server-oriented class that doesn't give you direct
4611 access to the underlying socket used.
4612
4613 Finally, test_support.HOST has been introduced, which should be used
4614 for the host argument of any relevant socket calls (i.e. bind and
4615 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004616
4617 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004618 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004619 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4620 test_asynchat and test_socket_ssl.
4621
Georg Brandl3ee81df2008-05-17 18:14:43 +00004622 It is now possible for multiple instances of the regression test
4623 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004902- Added the future_builtins module, which contains hex() and oct().
4903 These are the PEP 3127 version of these functions, designed to be
4904 compatible with the hex() and oct() builtins from Python 3.0. They
4905 differ slightly in their output formats from the existing, unchanged
4906 Python 2.6 builtins. The expected usage of the future_builtins
4907 module is:
4908 from future_builtins import hex, oct
4909
Eric Smith7ef40bf2008-02-20 23:34:22 +00004910- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4911 exponents for exponents with absolute value < 100. Follows C99
4912 standard. This is a change on Windows, which would use 3 digits.
4913 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4914 so that any alterations it does to the resulting string will be
4915 available in stringlib/formatter.h (for float.__format__).
4916
Eric Smith5a3c1352008-02-19 13:21:56 +00004917- Implemented PEP 3101, Advanced String Formatting. This adds a new
4918 builtin format(); a format() method for str and unicode; a
4919 __format__() method to object, str, unicode, int, long, float, and
4920 datetime; the class string.Formatter; and the C API
4921 PyObject_Format().
4922
Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- Fixed several potential crashes, all caused by specially crafted
4924 __del__ methods exploiting objects in temporarily inconsistent
4925 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004926
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004927- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928 prevent a possible crash: an Abstract Base Class would try to access
4929 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004930

Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Clear all free lists during a gc.collect() of the highest generation
4935 in order to allow pymalloc to free more arenas. Python may give back
4936 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Issue #2045: Fix an infinite recursion triggered when printing a
4939 subclass of collections.defaultdict, if its default_factory is set
4940 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004941
Christian Heimesf75dbef2008-02-08 00:11:31 +00004942- Fixed a minor memory leak in dictobject.c. The content of the free
4943 list was not freed on interpreter shutdown.
4944
Georg Brandl21e99f42010-03-07 15:23:59 +00004945- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004946 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004947
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4949 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004950 to compact the internal free lists of pre-allocted ints and floats.
4951
Georg Brandl3ee81df2008-05-17 18:14:43 +00004952- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4953 calls. Python expected the return type int but the fork familie
4954 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004955
Georg Brandl3ee81df2008-05-17 18:14:43 +00004956- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4957 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004965- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4966 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004967
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968- Patch #1473257: generator objects gain a gi_code attribute. This is
4969 the same object as the func_code attribute of the function that
4970 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004971
Georg Brandl3ee81df2008-05-17 18:14:43 +00004972- Issue #1920: "while 0" statements were completely removed by the
4973 compiler, even in the presence of an "else" clause, which is
4974 supposed to be run when the condition is false. Now the compiler
4975 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004976
Guido van Rossumeead05f2008-01-24 18:21:02 +00004977- A few crashers fixed: weakref_in_del.py (issue #1377858);
4978 loosing_dict_ref.py (issue #1303614, test67.py);
4979 borrowed_ref_[34].py (not in tracker).
4980
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004981- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004982 suppressed while an extension is loaded by calling SetErrorMode in

4984
Georg Brandl3ee81df2008-05-17 18:14:43 +00004985- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004986 several extension methods and modules do not work without unicode
4987 support.
4988
Georg Brandl26543b12008-01-21 18:36:51 +00004989- Issue #1882: when compiling code from a string, encoding cookies in the
4990 second line of code were not always recognized correctly.
4991
Georg Brandl14404b62008-01-19 19:27:05 +00004992- Issue #1679: "0x" was taken as a valid integer literal.
4993
Georg Brandl6caad7d2008-01-26 14:19:22 +00004994- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004995 added.
4996
Christian Heimesc94e2b52008-01-14 04:13:37 +00004997- sys.float_info / PyFloat_GetInfo: The floating point information
4998 object was converted from a dict to a specialized structseq object.
4999
Georg Brandl3ee81df2008-05-17 18:14:43 +00005000- Patch #1816: Added sys.flags structseq. It exposes the status of
5001 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005002
Georg Brandl3ee81df2008-05-17 18:14:43 +00005003- Objects/structseq.c: Implemented new structseq representation. The
5004 patch makes structseqs (e.g. the return value of os.stat) more
5005 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005006
Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005019- Improve some exception messages when Windows fails to load an
5020 extension module. Now we get for example '%1 is not a valid Win32
5021 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005029 and INF. float("nan"), float("inf") and float("-inf") now work on
5030 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005031
Georg Brandl3ee81df2008-05-17 18:14:43 +00005032- Compiler now generates simpler and faster code for dictionary
5033 literals. The oparg for BUILD_MAP now indicates an estimated
5034 dictionary size. There is a new opcode, STORE_MAP, for adding
5035 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005080 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5081 automatically shifts from ints to longs.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005083- Issue #1686386: Tuple's tp_repr did not take into account the
5084 possibility of having a self-referential tuple, which is possible
5085 from C code. Nor did object's tp_str consider that a type's tp_str
5086 could do something that could lead to an inifinite recursion.
5087 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5088 issues.

5091 'print' statement to write to a file since the GIL was not released
5092 as needed. Now PyObject_Print() does the right thing along with
5093 various tp_print implementations of the built-in types and those in
5094 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005104 PyObject_Call() never calling back out to Python code to trigger
5105 recursion depth updates/checks. Required the creation of a static

5155
Guido van Rossum143b5642007-03-23 04:58:42 +00005156- Bug #1683368: The object.__init__() and object.__new__() methods are
5157 now stricter in rejecting excess arguments. The only time when
5158 either allows excess arguments is when it is not overridden and the
5159 other one is. For backwards compatibility, when both are
5160 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005161 warning later). Also, type.__init__() insists on the same signature
5162 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005164- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5165 object to complex using its __complex__() method before falling back
5166 to the __float__() method. Therefore, the functions in the cmath
5167 module now can operate on objects that define a __complex__()
5168 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005186- Bug #1678647: write a newline after printing an exception in any
5187 case, even when converting the value to a string failed.
5188
Georg Brandl871f1bc2007-03-12 13:17:36 +00005189- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005190 its argument, if it exists. If not, it will work like before. This
5191 allows customizing the output of dir() in the presence of a
5192 __getattr__().

5202 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005203
Georg Brandlaa2321b2007-03-07 00:40:28 +00005204- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005205 makes the filenames the warning module prints much more sensible
5206 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005219- Patch #1674228: when assigning a slice (old-style), check for the
5220 sq_ass_slice instead of the sq_slice slot.
5221
Georg Brandl3ee81df2008-05-17 18:14:43 +00005222- When printing an unraisable error, don't print exceptions. before

Georg Brandl92a6bae2007-03-13 17:43:32 +00005791- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792 are set for invalid interpolation sequences that would lead to

Georg Brandl3ee81df2008-05-17 18:14:43 +00006134- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6135 with RFC 3207 and forgets any knowledge obtained from the server not
6136 obtained from the TLS negotiation itself. Patch contributed by Bill
6137 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006138
Georg Brandl3ee81df2008-05-17 18:14:43 +00006139- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006140 that the SMTP.starttls() caller no longer needs to call ehlo()
6141 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006142 does not claim to support starttls. Adds the
6143 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00006227

Georg Brandl3ee81df2008-05-17 18:14:43 +00006242 time so that opening a database previously created with the DB_DUP
6243 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6244 opens. Specifically: dictionary assignment to a DB object will
6245 replace all values for a given key when the database allows
6246 duplicate values. DB users should use DB.put(k, v) when they want
6247 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006248

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006526- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006527 periodic threadstate and signal checking in tight loops. By
6528 default, this option is turned-off. It should only be enabled in
6529 debugged, performance critical applications.

6580-----
6581
Georg Brandl3ee81df2008-05-17 18:14:43 +00006582- Unified naming convention for free lists and their limits. All free
6583 lists in Object/ are named ``free_list``, the counter ``numfree``
6584 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6585 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006586
Georg Brandl3ee81df2008-05-17 18:14:43 +00006587- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6588 to ``PyTuple_SetItem``, it can be used to populate a brand new
6589 frozenset; but it does not steal a reference to the added item.

6601
Georg Brandl3ee81df2008-05-17 18:14:43 +00006602- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6603 of w# format code incorrectly truncated the length to an int, even
6604 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6605 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006606
Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6627
6628- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6629 outside of pystate.c and should not be necessary.
6630
Georg Brandl3ee81df2008-05-17 18:14:43 +00006631- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6632 absolute imports. In earlier versions they might have used relative
6633 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006634
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6636 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006637
Georg Brandl3ee81df2008-05-17 18:14:43 +00006638- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006663- Removed the macfs module. It had been deprecated since Python 2.5.
6664 This lead to the deprecation of macostools.touched() as it relied
