153 by Andrew Bennetts.
154
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000155- Issue #9826: OrderedDict.__repr__ can now handle self-referential

164 This prevents user-created self-referencing ordered dictionaries from
165 becoming permanently uncollectable GC garbage. The downside is that
166 removing __del__ means that the internal doubly-linked list has to wait for
167 GC collection rather than freeing memory immediately when the refcnt drops
168 to zero.
169
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000170- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000171 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000172 value.
173
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000174- Issue #9792: In case of connection failure, socket.create_connection()
175 would swallow the exception and raise a new one, making it impossible
176 to fetch the original errno, or to filter timeout errors. Now the
177 original error is re-raised.
178
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000179- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
180 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
181 be updated back after the system call. Original patch by Brian Brazil.
182
Antoine Pitroudca9de92010-09-04 17:52:26 +0000183- Issue #1100562: Fix deep-copying of objects derived from the list and
184 dict types. Patch by Michele Orrù and Björn Lindqvist.
185
Fred Drakea1e627d2010-09-03 03:55:50 +0000186- Issue #7005: Fixed output of None values for RawConfigParser.write and
187 ConfigParser.write.
188
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000189- Issue #808164: Fixed socket.close to avoid references to globals, to
190 avoid issues when socket.close is called from a __del__ method.
191
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000192- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

194
R. David Murray7c4bf552010-08-25 01:45:57 +0000195- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
196 character years even if the message contains RFC822 two character years.
197
Daniel Stutzbach91287322010-08-24 21:09:30 +0000198- Issue #8750: Fixed MutableSet's methods to correctly handle
199 reflexive operations, namely x -= x and x ^= x.
200
Victor Stinnercaafd772010-09-08 10:51:01 +0000201- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000202 error handling when accepting a new connection.

210 module now correctly return a set. (Patch by Eli Bendersky.)
211
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000212- Issue #9617: Signals received during a low-level write operation aren't
213 ignored by the buffered IO layer anymore.
214
Benjamin Peterson52c36052010-08-21 03:03:22 +0000215- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
216 are not held onto after they are deleted elsewhere.
217
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000218- Issue #9626: the view methods for collections.OrderedDict() were returning
219 the unordered versions inherited from dict. Those methods are now
220 overridden to provide ordered views.
221
Éric Araujo0389ae62010-08-14 03:07:46 +0000222- Issue #8688: MANIFEST files created by distutils now include a magic
223 comment indicating they are generated. Manually maintained MANIFESTs
224 without this marker will not be overwritten or removed.
225
Antoine Pitroue1436d12010-08-12 15:25:51 +0000226- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

239 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
240
Antoine Pitrou99009162010-08-09 22:51:24 +0000241- Issue #3757: thread-local objects now support cyclic garbage collection.

619Core and Builtins
620-----------------
621
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000622- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
623 start byte and the continuation byte(s) are now considered invalid, instead
624 of the number of bytes specified by the start byte.
625 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
626 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
627 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
628 Previous versions returned a single u'\ufffd'.
629
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000630- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000631 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
632 arises from the "Overriding __eq__ blocks inheritance ..." warning
633 when turned into an exception: in this case the exception simply
634 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000635
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000636- Issue #8748: Fix two issues with comparisons between complex and integer
637 objects. (1) The comparison could incorrectly return True in some cases
638 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
639 (2) The comparison raised an OverflowError for large integers, leading
640 to unpredictable exceptions when combining integers and complex objects
641 in sets or dicts.
642
Mark Dickinson81336372010-05-30 12:12:25 +0000643- Issue #5211: Implicit coercion for the complex type is now completely
644 removed. (Coercion for arithmetic operations was already removed in 2.7
645 alpha 4, but coercion for rich comparisons was accidentally left in.)
646
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000647- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
648 and error handler, instead of writing to the C stderr file in utf-8
649
Georg Brandlfee0f442010-05-22 21:26:21 +0000650- Issue #7902: When using explicit relative import syntax, don't try implicit
651 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +0000652
Georg Brandlfee0f442010-05-22 21:26:21 +0000653- Issue #7079: Fix a possible crash when closing a file object while using it
654 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +0000655
Victor Stinnerb65bd2e2010-06-11 19:22:28 +0000656- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +0000657 Window Server again in a framework build on MacOSX 10.5 or earlier.

660-----
661
Georg Brandlfee0f442010-05-22 21:26:21 +0000662- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
663 of the interpreter to set sys.argv without also modifying sys.path. This
664 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +0000665 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

689
R. David Murray52dcd452010-06-02 22:03:15 +0000690- Issue #1368247: set_charset (and therefore MIMEText) now automatically

692
Alexander Belopolsky9292ee02010-05-27 20:55:27 +0000693- Issue #7150: Raise OverflowError if the result of adding or subtracting

781 non-float non-integer argument is now converted to an integer (if possible)
782 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +0000792 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable

883 the method could block indefinitely if called just before the event loop
884 started running. This also fixes the occasional freezes witnessed in
885 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +0000887- Issue #5103: SSL handshake would ignore the socket timeout and block
888 indefinitely if the other end didn't respond.
889
Georg Brandlfee0f442010-05-22 21:26:21 +0000890- The do_handshake() method of SSL objects now adjusts the blocking mode of the
891 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +0000901- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
902 string "python" as the *ident*. openlog() arguments are all optional and
903 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000983 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
984 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

1006-----------------
1007
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001008- Issue #7301: Add environment variable $PYTHONWARNINGS.
1009
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001010- Issue #8329: Don't return the same lists from select.select when no fds are
1011 changed.
1012
Georg Brandlfee0f442010-05-22 21:26:21 +00001013- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001014 on 64-bit machines. The shift count for either left or right shift is
1015 permitted to be up to sys.maxsize.
1016
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001017- Ensure that tokenization of identifiers is not affected by locale.

1022
Georg Brandlfee0f442010-05-22 21:26:21 +00001023- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1024 with a non-empty format string. This is an effort to future-proof user
1025 code. If a derived class does not currently implement __format__ but later
1026 adds its own __format__, it would most likely break user code that had
1027 supplied a format string. This will be changed to a DeprecationWaring in
1028 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001029
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001030- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +00001055- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001056 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

1060
Georg Brandlfee0f442010-05-22 21:26:21 +00001061- Issue #8257: The Decimal construct now accepts a float instance directly,
1062 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001063
1064 >>> Decimal(1.1)

1066
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001067- collections.Counter() now supports a subtract() method.
1068
Georg Brandlfee0f442010-05-22 21:26:21 +00001069- The functools module now has a total_ordering() class decorator to simplify
1070 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001071
Georg Brandlfee0f442010-05-22 21:26:21 +00001072- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +00001078- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1079 InvalidOperation instead of returning False. (Comparisons involving a quiet
1080 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1081 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001082
Georg Brandlfee0f442010-05-22 21:26:21 +00001083- Issue #2531: Comparison operations between floats and Decimal instances now
1084 return a result based on the numeric values of the operands; previously they
1085 returned an arbitrary result based on the relative ordering of id(float) and
1086 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001087
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001088- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001089 argument `-` which tells it to read files to compile from stdin. Each line is
1090 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00001096- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1097 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001098 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001100- Comparisons using one of <, <=, >, >= between a complex instance and a
1101 Fractions instance now raise TypeError instead of returning True/False. This
1102 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1103 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001104

Georg Brandlba83f822010-03-14 09:50:54 +00001517 file position when calling `truncate()`. It would previously change the file
1518 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001519 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1522 class used to represent files stored inside an archive. The new
1523 implementation is significantly faster and can be wrapped in a

1525 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1614-----------------
1615
Georg Brandlba83f822010-03-14 09:50:54 +00001616- The ``__complex__()`` method is now looked up on the class of instances to
1617 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001618
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001619- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1620 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1621
Mark Dickinson1b34d252010-01-01 17:27:30 +00001622- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001623 DeprecationWarning when passed a float argument where an integer was expected.
1624 These functions and methods now raise TypeError instead. The majority of the
1625 effects of this change are in the extension modules, but some core functions
1626 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1627 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001628

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001637- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1638 used to drop the time part of the result.
1639
Georg Brandlba83f822010-03-14 09:50:54 +00001640- Issue #1811: Improve accuracy and cross-platform consistency for true division
1641 of integers: the result of a/b is now correctly rounded for ints a and b (at
1642 least on IEEE 754 platforms), and in particular does not depend on the
1643 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001644
Georg Brandlba83f822010-03-14 09:50:54 +00001645- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1646 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1647 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001650 executables on OSX.
1651
Georg Brandlba83f822010-03-14 09:50:54 +00001652 These executables now work properly with the arch(1) command: ``arch -ppc
1653 python`` will start a universal binary version of python in PPC mode (unlike
1654 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001677 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1678 alternative to cPickle if you care about performance. Patch by Florent

1714 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1715 the same as passing no argument.
1716
Georg Brandlba83f822010-03-14 09:50:54 +00001717- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

1741 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

1811 decimal string that's guaranteed to round back to x under correct rounding
1812 (with round-half-to-even rounding mode). Previously it gave a string based on

1814 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1815 not supported (see below), repr is unchanged.

1818 conversions within Python are now correctly rounded. Places these conversions
1819 occur include: str for floats and complex numbers; the float and complex
1820 constructors; old-style and new-style numeric formatting; serialization and

Georg Brandlba83f822010-03-14 09:50:54 +00001825 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1826 providing correctly-rounded strtod and dtoa C functions. This code is
1827 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1828 the C compiler. There may be a small number of platforms on which correct
1829 operation of this code cannot be guaranteed, so the code is not used: notably,
1830 this applies to platforms where the C double format is not IEEE 754 binary64,
1831 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1832 and Python's configure script is unable to determine how to change the FPU
1833 precision. On these platforms conversions use the platform strtod and dtoa,
1834 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001836- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1837 uses the correctly-rounded string <-> float conversions described above (when
1838 available), and so produces correctly rounded results that will display nicely
1839 under the float repr. There are two related small changes: (1) round now
1840 accepts any class with an ``__index__()`` method for its second argument (but
1841 no longer accepts floats for the second argument), and (2) an excessively
1842 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1843 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002060- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002061 untrackable objects are not tracked by the garbage collector. This can reduce
2062 the size of collections and therefore the garbage collection overhead on
2063 long-running programs, depending on their particular use of datatypes.

2104
Georg Brandl29c6a282009-04-05 20:23:13 +00002105- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002106 were suppressing all exceptions. These include list(), filter(), map(),

2135
Georg Brandlba83f822010-03-14 09:50:54 +00002136- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2137 existing .py counterpart, override the co_filename attributes of all code
2138 objects if the original filename is obsolete (which can happen if the file has
2139 been renamed, moved, or if it is accessed through different paths). Patch by

2193
Georg Brandlba83f822010-03-14 09:50:54 +00002194- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2195 file objects with closefd=False. The file descriptor is still kept open but
2196 the file object behaves like a closed file. The ``FileIO`` object also got a
2197 new readonly attribute ``closefd``.

2216
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002217- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002220- On windows, ``os.chdir()`` given unicode was not working if
2221 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2222 this code path is really executed because I cannot move to such directory on
2223 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002225- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2226 element is temporarily replaced with an equivalent frozenset. But the
2227 eventual KeyError would always report the empty ``frozenset()`` as the missing
2228 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002248- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2249 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2250 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2251 of using the replace error handler in PyUnicode_DecodeUTF8().
2252
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002253- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002256- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2258 gives improved memory leak detection when running under Valgrind, while taking
2259 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003420 - Packing a float now always gives a Deprecation Warning. Previously it
3421 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003422
Georg Brandlba83f822010-03-14 09:50:54 +00003423 - If x is not an int, long or float, then packing x will always result in
3424 struct.error. Previously an x with an __int__ method could be packed by
3425 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3426 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3427 neither __int__ nor __long__, TypeError used to be raised (with a
3428 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3429 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003430
Georg Brandlba83f822010-03-14 09:50:54 +00003431 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3432 argument with an __int__ method can be packed, but use of this feature
3433 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003626- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3627 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3628 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3629 ``printf`` function, whereas PyString_FromFormat has an independent
3630 implementation and uses "%zd" on all platforms for size_t values.
3631 This makes a difference on win64, where ``printf`` needs "%Id" to display

Brett Cannon672237d2008-09-09 00:49:16 +00003701 return a list or None rather than a custom object.
3702
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003703- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003727 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3728 for catch_warnings() also led to an improvement in the raising of a
3729 DeprecationWarning related to warnings.warn_explicit().
3730
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003731- The deprecation warnings for the old camelCase threading API were removed.

3753
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003754- Issue #2975: When compiling several extension modules with Visual Studio 2008
3755 from the same python interpreter, some environment variables would grow
3756 without limit.
3757
Benjamin Peterson37346b22008-08-23 20:27:43 +00003758- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3759 exploitation of poor argument checking.
3760
Gerhard Häringef2276b2008-09-12 13:54:06 +00003761- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3762
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003763- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003795What's New in Python 2.6 beta 3?
3796================================
3797
Barry Warsaw07a4a382008-08-21 01:15:08 +00003798*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003799
3800Core and Builtins
3801-----------------
3802
Guido van Rossumf8402962008-08-20 15:01:50 +00003803- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3804 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3805 extensions do not automatically benefit from the class attribute
3806 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3807 to their tp_flags field if they care. This is a backwards
3808 compatibility feature; in 3.0, all types will use the cache by
3809 default.
3810
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003811- Keyword arguments can now follow starred arguments. (``f(a, *args,
3812 keyword=23)`` is now valid syntax.)
3813
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003814- ctypes function pointers that are COM methods have a boolean True
3815 value again.
3816
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003817- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3818 by denying s# to parse objects that have a releasebuffer procedure,
3819 and introducing s*.
3820
Georg Brandl1e13ea92008-08-11 09:07:59 +00003821- Issue #3537: Fix an assertion failure when an empty but presized dict
3822 object was stored in the freelist.
3823
Mark Dickinsonb6467572008-08-04 21:30:09 +00003824- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3825 ValueError consistently across platforms.
3826
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003827- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3828 (64bit Unix, for example), unichr() would truncate its argument and return
3829 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3830
Neal Norwitze7d8be82008-07-31 17:17:14 +00003831- Apply security patches from Apple.
3832
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003833- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3834 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3835
Antoine Pitrou92f82162008-07-25 22:22:08 +00003836- Issue #1819: function calls with several named parameters are now on
3837 average 35% faster (as measured by pybench).
3838
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003839- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3840 the python debugger steps into a class statement: the free variables (local
3841 variables defined in an outer scope) would be deleted from the outer scope.
3842
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003843- Issue #2620: Overflow checking when allocating or reallocating memory
3844 was not always being done properly in some python types and extension
3845 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3846 all been updated to perform better checks and places in the code that
3847 would previously leak memory on the error path when such an allocation
3848 failed have been fixed.
3849

3851-------
3852
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003853- Issue #3612: Added some missing basic types in ctypes.wintypes.
3854
Benjamin Petersone977ad42008-08-20 01:42:01 +00003855- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3856 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3857
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003858- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3859 version reported by these tools does not necessarily follow the python
3860 version numbering scheme, so the module is less strict when parsing it.
3861
Nick Coghlanf70385a2008-08-18 12:42:46 +00003862- Issue #2235: Added Py3k warnings for types which will become unhashable
3863 under the stricter __hash__ inheritance rules in 3.0. Several types
3864 which did not meet the rules for hash invariants and were already
3865 unhashable in 3.0 have now been explicitly flagged as unhashable in
3866 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3867 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3868
Brett Cannon88f801d2008-08-18 00:46:22 +00003869- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3877
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003878- Issue #3575: Incremental decoder's decode function now takes bytearray
3879 by using 's*' instead of 't#'.
3880
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003881- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003882 fails unicode conversion on 2nd parameter. (windows only)
3883
Georg Brandl222e2082010-08-01 22:27:39 +00003884- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003885 in a redirect.
3886
Brett Cannonabe423e2008-08-16 21:47:07 +00003887- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003888 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003889
Facundo Batistaeb90b782008-08-16 14:44:07 +00003890- Issue #2776: fixed small issue when handling an URL with double slash
3891 after a 302 response in the case of not going through a proxy.
3892
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003893- Issue #2676: in the email package, content-type parsing was hanging on
3894 pathological input because of quadratic or exponential behaviour of a
3895 regular expression.
3896
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003897- Issue #3476: binary buffered reading through the new "io" library is now
3898 thread-safe.
3899
Brett Cannonbf3157b2008-08-14 05:00:03 +00003900- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3901 since mimetools itself is deprecated. Because modules are cached, all
3902 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3903
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003904- Issue #3134: shutil referenced undefined WindowsError symbol.
3905
Robert Schuppenies14646332008-08-10 11:01:53 +00003906- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3907 menu entries were not deleted.
3908
Brett Cannon83e81842008-08-09 23:30:55 +00003909- Copied the implementation of reduce() to _functools.reduce() to have a
3910 version that did not raise a DeprecationWarning under -3.
3911
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003912- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3913 a MemoryError rather than silently stop the iteration.
3914
Guido van Rossum59ce9012008-08-09 14:55:34 +00003915- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3916 to _sre.compile() will now be rejected. This should not affect anybody
3917 since the re.compile() function never generates invalid re-bytecode.
3918
Skip Montanaroa032bf42008-08-08 22:52:51 +00003919- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3920 upon first access it can be automatically initialized from the csv file if
3921 it wasn't initialized during instantiation.
3922
Brett Cannon3aa2a492008-08-06 22:28:09 +00003923- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3924 the reload() built-in has been removed.
3925
Brett Cannon7e30b672008-08-04 21:52:25 +00003926- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003927 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003938 asking for a specific length. This problem only affected files opened
3939 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003940

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003964- Issue #3394: zipfile.writestr sets external attributes when passed a
3965 file name rather than a ZipInfo instance, so files are extracted with
3966 mode 0600 rather than 000 under Unix.
3967
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003968- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3969 argument in python 2.5, this broke code that subclassed Popen to include its

3981 interaction with the tp_hash slot (added in 2.6b2) are now documented
3982
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003983- Issue #643841: The language reference now provides more detailed
3984 coverage of the lookup process for special methods. The disclaimers
3985 regarding lack of coverage of new-style classes have also been
3986 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003989What's New in Python 2.6 beta 2?
3990================================
3991
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003992*Release date: 17-Jul-2008*
3993
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003994Core and Builtins
3995-----------------
3996
Georg Brandl3e483f62008-07-16 22:57:41 +00003997- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3998 its methods now allow for items objects that can be converted to
3999 an integer using operator.index().
4000
Mark Dickinson64b7e502008-07-16 09:40:03 +00004001- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4002 produced a ValueError instead of giving the correct float.
4003
Eric Smitha5fa5a22008-07-16 00:11:49 +00004004- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4005 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4006
Mark Dickinson7103aa42008-07-15 19:08:33 +00004007- Issue #3008: the float type has a new instance method 'float.hex'
4008 and a new class method 'float.fromhex' to convert floating-point
4009 numbers to and from hexadecimal strings, respectively.
4010
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004011- Issue #2235: __hash__ is once again inherited by default. To allow
4012 collections.Hashable to remain meaningful in the presence of the
4013 default hash implementation (object.__hash__), it is now possible
4014 to explicit block inheritance of hash by setting __hash__=None at
4015 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4016 level.
4017
Nick Coghlanb028f502008-07-13 14:52:36 +00004018- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4019 the parent module cannot be found while performing an absolute import.
4020 This means that an incorrectly defined __package__ attribute will
4021 now only prevent relative imports in that module rather than causing
4022 all imports from that module to fail.
4023
Nick Coghlan14ff9942008-07-08 14:21:42 +00004024- Issue #2517: Allow unicode messages in Exceptions again by correctly
4025 bypassing the instance dictionary when looking up __unicode__ on
4026 new-style classes.
4027
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004028- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4029 set to a custom object whose write() method happens to install
4030 another file in sys.stdout.
4031
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004032- Issue #3088: Corrected a race condition in classes derived from
4033 threading.local: the first member set by a thread could be saved in
4034 another thread's dictionary.
4035
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004036- Issue #3004: Minor change to slice.indices(): the start and stop
4037 arguments are now treated identically, making the behaviour easier
4038 to describe and understand. For example, slice(None, -10,
4039 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4040 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4041 10, -1).
4042
Georg Brandl278fc502008-07-19 12:46:12 +00004043- Issue #3219: Calling a function with repeated keyword arguments,
4044 f(a=2, a=23), would not cause a syntax error. This was a regression
4045 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004046
Georg Brandl278fc502008-07-19 12:46:12 +00004047- Issue #2862: Make int and float freelist management consistent with
4048 other freelists. Changes their CompactFreeList apis into
4049 ClearFreeList apis and calls them via gc.collect().

4053
Thomas Heller57adf222008-08-14 19:10:48 +00004054- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4055 api functions without holding the GIL, which could lead to a fatal
4056 error when they failed.
4057
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004058- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4067 ForkingPickler.register() to resolve conflict with ctypes.
4068
Vinay Sajip51e65192008-07-18 09:01:10 +00004069- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004070

4072 a valid dlerror() message.
4073
Thomas Heller2bad6572008-07-15 17:19:50 +00004074- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4075 incomplete structure was created.

4080
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004081- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004082
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004083- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4084 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004085 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004086 content-length. The problem had been corrected in the 2.4 branch, but never
4087 merged into trunk.
4088
Georg Brandle78fbcc2008-07-05 10:13:36 +00004089- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00004101
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004102- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4103 handling is now the same as that of other special attributes like __name__).
4104
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004105- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4106 removal in Python 3.0 in favor of urllib2.urlopen().

4558 original Python code has been kept as backup). This will allow for
4559 using the 'warning's machinery in such places as the parser where
4560 use of pure Python code is not possible. Both the ``showarning()``
4561 and ``formatwarning()`` gain an optional 'line' argument which is
4562 not called by default for backwards-compatibility reasons. Setting
4563 ``warnings.showwarning()`` to an implementation that lacks support
4564 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- Issue #2550: The approach used by client/server code for obtaining
4628 ports to listen on in network-oriented tests has been refined in an
4629 effort to facilitate running multiple instances of the entire
4630 regression test suite in parallel without issue.
4631 test_support.bind_port() has been fixed such that it will always
4632 return a unique port -- which wasn't always the case with the
4633 previous implementation, especially if socket options had been set
4634 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4635 new implementation of bind_port() will actually raise an exception
4636 if it is passed an AF_INET/SOCK_STREAM socket with either the
4637 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4638 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4639 the socket it's been passed. This currently only applies to
4640 Windows. This option prevents any other sockets from binding to the
4641 host/port we've bound to, thus removing the possibility of the
4642 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4643 when a second SOCK_STREAM socket binds and accepts to a host/port
4644 that's already been bound by another socket. The optional preferred
4645 port parameter to bind_port() has been removed. Under no
4646 circumstances should tests be hard coding ports!
4647
4648 test_support.find_unused_port() has also been introduced, which will
4649 pass a temporary socket object to bind_port() in order to obtain an
4650 unused port. The temporary socket object is then closed and
4651 deleted, and the port is returned. This method should only be used
4652 for obtaining an unused port in order to pass to an external program
4653 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4654 a parameter to a server-oriented class that doesn't give you direct
4655 access to the underlying socket used.
4656
4657 Finally, test_support.HOST has been introduced, which should be used
4658 for the host argument of any relevant socket calls (i.e. bind and
4659 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004660
4661 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004662 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004663 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4664 test_asynchat and test_socket_ssl.
4665
Georg Brandl3ee81df2008-05-17 18:14:43 +00004666 It is now possible for multiple instances of the regression test
4667 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004936- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004937 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00004946- Added the future_builtins module, which contains hex() and oct().
4947 These are the PEP 3127 version of these functions, designed to be
4948 compatible with the hex() and oct() builtins from Python 3.0. They
4949 differ slightly in their output formats from the existing, unchanged
4950 Python 2.6 builtins. The expected usage of the future_builtins
4951 module is:
4952 from future_builtins import hex, oct
4953
Eric Smith7ef40bf2008-02-20 23:34:22 +00004954- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4955 exponents for exponents with absolute value < 100. Follows C99
4956 standard. This is a change on Windows, which would use 3 digits.
4957 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4958 so that any alterations it does to the resulting string will be
4959 available in stringlib/formatter.h (for float.__format__).
4960
Eric Smith5a3c1352008-02-19 13:21:56 +00004961- Implemented PEP 3101, Advanced String Formatting. This adds a new
4962 builtin format(); a format() method for str and unicode; a
4963 __format__() method to object, str, unicode, int, long, float, and
4964 datetime; the class string.Formatter; and the C API
4965 PyObject_Format().
4966
Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Fixed several potential crashes, all caused by specially crafted
4968 __del__ methods exploiting objects in temporarily inconsistent
4969 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004970
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004971- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004972 prevent a possible crash: an Abstract Base Class would try to access
4973 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Clear all free lists during a gc.collect() of the highest generation
4979 in order to allow pymalloc to free more arenas. Python may give back
4980 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004981
Georg Brandl3ee81df2008-05-17 18:14:43 +00004982- Issue #2045: Fix an infinite recursion triggered when printing a
4983 subclass of collections.defaultdict, if its default_factory is set
4984 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004985
Christian Heimesf75dbef2008-02-08 00:11:31 +00004986- Fixed a minor memory leak in dictobject.c. The content of the free
4987 list was not freed on interpreter shutdown.
4988
Georg Brandl21e99f42010-03-07 15:23:59 +00004989- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4993 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004994 to compact the internal free lists of pre-allocted ints and floats.
4995
Georg Brandl3ee81df2008-05-17 18:14:43 +00004996- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4997 calls. Python expected the return type int but the fork familie
4998 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004999

Georg Brandl3ee81df2008-05-17 18:14:43 +00005012- Patch #1473257: generator objects gain a gi_code attribute. This is
5013 the same object as the func_code attribute of the function that
5014 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005015
Georg Brandl3ee81df2008-05-17 18:14:43 +00005016- Issue #1920: "while 0" statements were completely removed by the
5017 compiler, even in the presence of an "else" clause, which is
5018 supposed to be run when the condition is false. Now the compiler
5019 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005020
Guido van Rossumeead05f2008-01-24 18:21:02 +00005021- A few crashers fixed: weakref_in_del.py (issue #1377858);

5028
Georg Brandl3ee81df2008-05-17 18:14:43 +00005029- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005030 several extension methods and modules do not work without unicode
5031 support.
5032

5037
Georg Brandl6caad7d2008-01-26 14:19:22 +00005038- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005039 added.
5040
Christian Heimesc94e2b52008-01-14 04:13:37 +00005041- sys.float_info / PyFloat_GetInfo: The floating point information
5042 object was converted from a dict to a specialized structseq object.
5043
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044- Patch #1816: Added sys.flags structseq. It exposes the status of
5045 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005046
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005051- Patch #1700288: added a type attribute cache that caches method
5052 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005053
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005054- Bug #1776: __import__() no longer accepts filenames on any platform.
5055 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005057- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5058
Georg Brandl3ee81df2008-05-17 18:14:43 +00005059- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5060 envvar and sys.dont_write_bytecode attribute. All these can be set
5061 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005062
Georg Brandl3ee81df2008-05-17 18:14:43 +00005063- Improve some exception messages when Windows fails to load an
5064 extension module. Now we get for example '%1 is not a valid Win32
5065 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005072- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073 and INF. float("nan"), float("inf") and float("-inf") now work on
5074 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005076- Compiler now generates simpler and faster code for dictionary
5077 literals. The oparg for BUILD_MAP now indicates an estimated
5078 dictionary size. There is a new opcode, STORE_MAP, for adding
5079 entries to the dictionary.

5091
Nick Coghlanef01d822007-12-03 12:55:17 +00005092- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005108- Patch #1739468: Directories and zipfiles containing a __main__.py
5109 file can now be directly executed by passing their name to the
5110 interpreter. The directory/zipfile is automatically inserted as the
5111 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005112
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113- Issue #1265: Fix a problem with sys.settrace, if the tracing
5114 function uses a generator expression when at the same time the
5115 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005116
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005117- sets and frozensets now have an isdisjoint() method.
5118

5122
Georg Brandl21e99f42010-03-07 15:23:59 +00005123- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5125 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005126
Georg Brandl3ee81df2008-05-17 18:14:43 +00005127- Issue #1686386: Tuple's tp_repr did not take into account the
5128 possibility of having a self-referential tuple, which is possible
5129 from C code. Nor did object's tp_str consider that a type's tp_str
5130 could do something that could lead to an inifinite recursion.
5131 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5132 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- Issue #1164: It was possible to trigger deadlock when using the
5135 'print' statement to write to a file since the GIL was not released
5136 as needed. Now PyObject_Print() does the right thing along with
5137 various tp_print implementations of the built-in types and those in
5138 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005139
Georg Brandl3ee81df2008-05-17 18:14:43 +00005140- Issue #1147: Exceptions were directly allowing string exceptions in
5141 their throw() method even though string exceptions no longer
5142 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005143
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- Issue #1096: Prevent a segfault from getting the repr of a very
5145 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005146
Brett Cannon1e534b52007-09-07 04:18:30 +00005147- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148 PyObject_Call() never calling back out to Python code to trigger
5149 recursion depth updates/checks. Required the creation of a static
5150 RuntimeError instance in case normalizing an exception put the
5151 recursion check value past its limit. Fixes crashers
5152 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005153

Neal Norwitz0ac60192007-05-27 04:08:54 +00005167- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005168 __*__ attributes. (Some already existed, e.g., __doc__ and
5169 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005170
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005171- Add -3 option to the interpreter to warn about features that are
5172 deprecated and will be changed/removed in Python 3.0.
5173
Georg Brandl2134e752007-05-21 20:34:16 +00005174- Patch #1686487: you can now pass any mapping after '**' in function
5175 calls.
5176
Collin Winter62903052007-05-18 23:11:24 +00005177- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005178 "except E as target:". This is to provide forwards compatibility
5179 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005180
Brett Cannon229cee22007-05-05 01:34:02 +00005181- Deprecate BaseException.message as per PEP 352.
5182
Georg Brandl3ee81df2008-05-17 18:14:43 +00005183- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005184 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005185
Vinay Sajip8549ce32007-05-06 17:53:37 +00005186- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005187 setting a plain string, ie don't expand to single letter identifiers.
5188
Raymond Hettinger13936692007-04-11 18:40:58 +00005189- Request #1191699: Slices can now be pickled.
5190
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005191- Request #1193128: str.translate() now allows a None argument for
5192 translations that only remove characters without re-mapping the
5193 remaining characters.
5194
Georg Brandl5cb76c12007-03-21 09:00:39 +00005195- Patch #1682205: a TypeError while unpacking an iterable is no longer
5196 masked by a generic one with the message "unpack non-sequence".
5197
Neal Norwitzaa754b72007-03-21 06:39:48 +00005198- Remove unused file Python/fmod.c.
5199
Guido van Rossum143b5642007-03-23 04:58:42 +00005200- Bug #1683368: The object.__init__() and object.__new__() methods are
5201 now stricter in rejecting excess arguments. The only time when
5202 either allows excess arguments is when it is not overridden and the
5203 other one is. For backwards compatibility, when both are
5204 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005205 warning later). Also, type.__init__() insists on the same signature
5206 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005207
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5209 object to complex using its __complex__() method before falling back
5210 to the __float__() method. Therefore, the functions in the cmath
5211 module now can operate on objects that define a __complex__()
5212 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- Patch #1623563: allow __class__ assignment for classes with
5215 __slots__. The old and the new class are still required to have the
5216 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005217
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Patch #1642547: Fix an error/crash when encountering syntax errors

5222 ``object.__reduce_ex__()`` is called with an object that is faking
5223 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Patch #1680015: Don't modify __slots__ tuple if it contains an

5229
Georg Brandl7b9c5552007-03-12 14:30:05 +00005230- Bug #1678647: write a newline after printing an exception in any
5231 case, even when converting the value to a string failed.
5232
Georg Brandl871f1bc2007-03-12 13:17:36 +00005233- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005234 its argument, if it exists. If not, it will work like before. This
5235 allows customizing the output of dir() in the presence of a
5236 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005237
Collin Winter276887b2007-03-12 16:11:39 +00005238- Patch #922167: Python no longer segfaults when faced with infinitely
5239 self-recursive reload() calls (as reported by bug #742342).
5240
Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005244- Patch #1491866: change the complex() constructor to allow
5245 parthensized forms. This means complex(repr(x)) now works instead of
5246 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005247
Georg Brandlaa2321b2007-03-07 00:40:28 +00005248- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005249 makes the filenames the warning module prints much more sensible
5250 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005251

5253 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 variable is given, but break into the interactive interpreter just
5255 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005263- Patch #1674228: when assigning a slice (old-style), check for the
5264 sq_ass_slice instead of the sq_slice slot.
5265
Georg Brandl3ee81df2008-05-17 18:14:43 +00005266- When printing an unraisable error, don't print exceptions. before
5267 the name. This duplicates the behavior whening normally printing
5268 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005801 AttributeError instead of an IOError when the server's response
5802 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005803

Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- Patch #1429539: pdb now correctly initializes the __main__ module
5809 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005810 correctly now.
5811

5818
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Patch #1530482: add pydoc.render_doc() which returns the

5834
Georg Brandl92a6bae2007-03-13 17:43:32 +00005835- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005836 are set for invalid interpolation sequences that would lead to
5837 errors on reading back those values.

5880 returned string up to the first NUL character.

5891
Georg Brandl3ee81df2008-05-17 18:14:43 +00005892- unittest now verifies more of its assumptions. In particular,
5893 TestCase and TestSuite subclasses (not instances) are no longer
5894 accepted in TestSuite.addTest(). This should cause no
5895 incompatibility since it never made sense with ordinary subclasses
5896 -- the failure just occurred later, with a more cumbersome
5897 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006184 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006267- Marshal.dumps() now expects exact type matches for int, long, float,
6268 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6269 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006285- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006286 time so that opening a database previously created with the DB_DUP
6287 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6288 opens. Specifically: dictionary assignment to a DB object will
6289 replace all values for a given key when the database allows
6290 duplicate values. DB users should use DB.put(k, v) when they want
6291 to store duplicates; not DB[k] = v.

6298 characters with ASCII value less than 32. Also, it correctly quotes
6299 dots only if they occur on a single line, as opposed to the previous
6300 behavior of quoting dots if they are the second character of any
6301 line.

6647 of w# format code incorrectly truncated the length to an int, even
6648 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6649 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006679- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6680 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
