148

153 SSLSocket.sendto() to match the corresponding socket methods. Also,
154 fix various SSLSocket methods to raise socket.error rather than an

156 by Andrew Bennetts.
157
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000158- Issue #9826: OrderedDict.__repr__ can now handle self-referential

Raymond Hettinger20397532010-09-12 02:11:45 +0000166- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
167 This prevents user-created self-referencing ordered dictionaries from
168 becoming permanently uncollectable GC garbage. The downside is that
169 removing __del__ means that the internal doubly-linked list has to wait for
170 GC collection rather than freeing memory immediately when the refcnt drops
171 to zero.
172
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000173- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000174 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000175 value.
176
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000177- Issue #9792: In case of connection failure, socket.create_connection()
178 would swallow the exception and raise a new one, making it impossible
179 to fetch the original errno, or to filter timeout errors. Now the
180 original error is re-raised.
181
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000182- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
183 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
184 be updated back after the system call. Original patch by Brian Brazil.
185
Antoine Pitroudca9de92010-09-04 17:52:26 +0000186- Issue #1100562: Fix deep-copying of objects derived from the list and
187 dict types. Patch by Michele Orrù and Björn Lindqvist.
188
Fred Drakea1e627d2010-09-03 03:55:50 +0000189- Issue #7005: Fixed output of None values for RawConfigParser.write and
190 ConfigParser.write.
191
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000192- Issue #808164: Fixed socket.close to avoid references to globals, to
193 avoid issues when socket.close is called from a __del__ method.
194
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000195- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

197
R. David Murray7c4bf552010-08-25 01:45:57 +0000198- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
199 character years even if the message contains RFC822 two character years.
200
Daniel Stutzbach91287322010-08-24 21:09:30 +0000201- Issue #8750: Fixed MutableSet's methods to correctly handle
202 reflexive operations, namely x -= x and x ^= x.
203
Victor Stinnercaafd772010-09-08 10:51:01 +0000204- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000205 error handling when accepting a new connection.
206

213 module now correctly return a set. (Patch by Eli Bendersky.)
214
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000215- Issue #9617: Signals received during a low-level write operation aren't
216 ignored by the buffered IO layer anymore.
217
Benjamin Peterson52c36052010-08-21 03:03:22 +0000218- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
219 are not held onto after they are deleted elsewhere.
220
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000221- Issue #9626: the view methods for collections.OrderedDict() were returning
222 the unordered versions inherited from dict. Those methods are now
223 overridden to provide ordered views.
224
Éric Araujo0389ae62010-08-14 03:07:46 +0000225- Issue #8688: MANIFEST files created by distutils now include a magic
226 comment indicating they are generated. Manually maintained MANIFESTs
227 without this marker will not be overwritten or removed.
228
Antoine Pitroue1436d12010-08-12 15:25:51 +0000229- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000233- Issue #9550: a BufferedReader could issue an additional read when the

Fred Drake0a1fa0e2010-08-10 13:09:54 +0000238- Issue #9551: Don't raise TypeError when setting the value to None for

242 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
243
Antoine Pitrou99009162010-08-09 22:51:24 +0000244- Issue #3757: thread-local objects now support cyclic garbage collection.

267 does not contain a '-', instead of raising an error.

622Core and Builtins
623-----------------
624
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000625- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
626 start byte and the continuation byte(s) are now considered invalid, instead
627 of the number of bytes specified by the start byte.
628 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
629 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
630 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
631 Previous versions returned a single u'\ufffd'.
632
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000633- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000634 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
635 arises from the "Overriding __eq__ blocks inheritance ..." warning
636 when turned into an exception: in this case the exception simply
637 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000638
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000639- Issue #8748: Fix two issues with comparisons between complex and integer
640 objects. (1) The comparison could incorrectly return True in some cases
641 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
642 (2) The comparison raised an OverflowError for large integers, leading
643 to unpredictable exceptions when combining integers and complex objects
644 in sets or dicts.
645
Mark Dickinson81336372010-05-30 12:12:25 +0000646- Issue #5211: Implicit coercion for the complex type is now completely
647 removed. (Coercion for arithmetic operations was already removed in 2.7
648 alpha 4, but coercion for rich comparisons was accidentally left in.)
649
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000650- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
651 and error handler, instead of writing to the C stderr file in utf-8
652
Georg Brandlfee0f442010-05-22 21:26:21 +0000653- Issue #7902: When using explicit relative import syntax, don't try implicit
654 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +0000655
Georg Brandlfee0f442010-05-22 21:26:21 +0000656- Issue #7079: Fix a possible crash when closing a file object while using it
657 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +0000658
Victor Stinnerb65bd2e2010-06-11 19:22:28 +0000659- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +0000660 Window Server again in a framework build on MacOSX 10.5 or earlier.

663-----
664
Georg Brandlfee0f442010-05-22 21:26:21 +0000665- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
666 of the interpreter to set sys.argv without also modifying sys.path. This
667 helps fix `CVE-2008-5983

692
R. David Murray52dcd452010-06-02 22:03:15 +0000693- Issue #1368247: set_charset (and therefore MIMEText) now automatically

695
Alexander Belopolsky9292ee02010-05-27 20:55:27 +0000696- Issue #7150: Raise OverflowError if the result of adding or subtracting

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

886 the method could block indefinitely if called just before the event loop
887 started running. This also fixes the occasional freezes witnessed in
888 test_httpservers.
Antoine Pitroua6240402010-04-25 21:40:32 +0000889
Antoine Pitroufc69af12010-04-24 20:04:58 +0000890- Issue #5103: SSL handshake would ignore the socket timeout and block
891 indefinitely if the other end didn't respond.
892
Georg Brandlfee0f442010-05-22 21:26:21 +0000893- The do_handshake() method of SSL objects now adjusts the blocking mode of the
894 SSL structure if necessary (as other methods already do).

1010
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001011- Issue #7301: Add environment variable $PYTHONWARNINGS.
1012
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001013- Issue #8329: Don't return the same lists from select.select when no fds are
1014 changed.
1015
Georg Brandlfee0f442010-05-22 21:26:21 +00001016- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001017 on 64-bit machines. The shift count for either left or right shift is
1018 permitted to be up to sys.maxsize.
1019
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001020- Ensure that tokenization of identifiers is not affected by locale.

1025
Georg Brandlfee0f442010-05-22 21:26:21 +00001026- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1027 with a non-empty format string. This is an effort to future-proof user
1028 code. If a derived class does not currently implement __format__ but later
1029 adds its own __format__, it would most likely break user code that had
1030 supplied a format string. This will be changed to a DeprecationWaring in
1031 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001064- Issue #8257: The Decimal construct now accepts a float instance directly,
1065 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001066

Raymond Hettinger34c35b22010-04-03 10:22:00 +00001070- collections.Counter() now supports a subtract() method.
1071
Georg Brandlfee0f442010-05-22 21:26:21 +00001072- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001081- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1082 InvalidOperation instead of returning False. (Comparisons involving a quiet
1083 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1084 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001085
Georg Brandlfee0f442010-05-22 21:26:21 +00001086- Issue #2531: Comparison operations between floats and Decimal instances now
1087 return a result based on the numeric values of the operands; previously they
1088 returned an arbitrary result based on the relative ordering of id(float) and
1089 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001090
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001091- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001092 argument `-` which tells it to read files to compile from stdin. Each line is
1093 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001103- Comparisons using one of <, <=, >, >= between a complex instance and a
1104 Fractions instance now raise TypeError instead of returning True/False. This
1105 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1106 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001520 file position when calling `truncate()`. It would previously change the file
1521 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001522 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1525 class used to represent files stored inside an archive. The new
1526 implementation is significantly faster and can be wrapped in a

1528 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1617-----------------
1618
Georg Brandlba83f822010-03-14 09:50:54 +00001619- The ``__complex__()`` method is now looked up on the class of instances to
1620 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001621
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001622- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1623 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1624
Mark Dickinson1b34d252010-01-01 17:27:30 +00001625- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001626 DeprecationWarning when passed a float argument where an integer was expected.
1627 These functions and methods now raise TypeError instead. The majority of the
1628 effects of this change are in the extension modules, but some core functions
1629 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1630 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001631

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001640- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1641 used to drop the time part of the result.
1642
Georg Brandlba83f822010-03-14 09:50:54 +00001643- Issue #1811: Improve accuracy and cross-platform consistency for true division
1644 of integers: the result of a/b is now correctly rounded for ints a and b (at
1645 least on IEEE 754 platforms), and in particular does not depend on the
1646 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001647
Georg Brandlba83f822010-03-14 09:50:54 +00001648- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1649 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1650 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001653 executables on OSX.
1654
Georg Brandlba83f822010-03-14 09:50:54 +00001655 These executables now work properly with the arch(1) command: ``arch -ppc
1656 python`` will start a universal binary version of python in PPC mode (unlike
1657 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001671- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
1672 allowing for a maximum number of tasks within the pool to be completed by the
1673 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00001679- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001680 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1681 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +00001682 Xicluna.

1718 the same as passing no argument.
1719
Georg Brandlba83f822010-03-14 09:50:54 +00001720- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00001742- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
1743 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
1744 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
1745 float arguments for integer format codes (other than 'L'): previously an
1746 attempt to pass a float resulted in a DeprecationWarning; now it gives a

Georg Brandlba83f822010-03-14 09:50:54 +00001828 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1829 providing correctly-rounded strtod and dtoa C functions. This code is
1830 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1831 the C compiler. There may be a small number of platforms on which correct
1832 operation of this code cannot be guaranteed, so the code is not used: notably,
1833 this applies to platforms where the C double format is not IEEE 754 binary64,
1834 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1835 and Python's configure script is unable to determine how to change the FPU
1836 precision. On these platforms conversions use the platform strtod and dtoa,
1837 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001839- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1840 uses the correctly-rounded string <-> float conversions described above (when
1841 available), and so produces correctly rounded results that will display nicely
1842 under the float repr. There are two related small changes: (1) round now
1843 accepts any class with an ``__index__()`` method for its second argument (but
1844 no longer accepts floats for the second argument), and (2) an excessively
1845 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1846 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002064 untrackable objects are not tracked by the garbage collector. This can reduce
2065 the size of collections and therefore the garbage collection overhead on
2066 long-running programs, depending on their particular use of datatypes.

2196
Georg Brandlba83f822010-03-14 09:50:54 +00002197- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2198 file objects with closefd=False. The file descriptor is still kept open but
2199 the file object behaves like a closed file. The ``FileIO`` object also got a
2200 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00002223- On windows, ``os.chdir()`` given unicode was not working if
2224 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2225 this code path is really executed because I cannot move to such directory on
2226 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002228- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2229 element is temporarily replaced with an equivalent frozenset. But the
2230 eventual KeyError would always report the empty ``frozenset()`` as the missing

2252 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2253 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2254 of using the replace error handler in PyUnicode_DecodeUTF8().
2255
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002256- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003423 - Packing a float now always gives a Deprecation Warning. Previously it
3424 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003425
Georg Brandlba83f822010-03-14 09:50:54 +00003426 - If x is not an int, long or float, then packing x will always result in
3427 struct.error. Previously an x with an __int__ method could be packed by
3428 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3429 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3430 neither __int__ nor __long__, TypeError used to be raised (with a
3431 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3432 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003433
Georg Brandlba83f822010-03-14 09:50:54 +00003434 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3435 argument with an __int__ method can be packed, but use of this feature
3436 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003629- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3630 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3631 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3632 ``printf`` function, whereas PyString_FromFormat has an independent
3633 implementation and uses "%zd" on all platforms for size_t values.
3634 This makes a difference on win64, where ``printf`` needs "%Id" to display

Nick Coghland2e09382008-09-11 12:11:06 +00003703- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003704 return a list or None rather than a custom object.
3705
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003706- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003730 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3731 for catch_warnings() also led to an improvement in the raising of a
3732 DeprecationWarning related to warnings.warn_explicit().
3733
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003734- The deprecation warnings for the old camelCase threading API were removed.

3756
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003757- Issue #2975: When compiling several extension modules with Visual Studio 2008
3758 from the same python interpreter, some environment variables would grow
3759 without limit.
3760
Benjamin Peterson37346b22008-08-23 20:27:43 +00003761- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3762 exploitation of poor argument checking.
3763
Gerhard Häringef2276b2008-09-12 13:54:06 +00003764- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3765
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003766- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3767 remaining ones have "pysqlite_" prefix.

3777 wrapper for warnings.catch_warnings() that makes it easier to check
3778 that expected warning messages are being reported.
3779

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003798What's New in Python 2.6 beta 3?
3799================================
3800
Barry Warsaw07a4a382008-08-21 01:15:08 +00003801*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003802
3803Core and Builtins
3804-----------------
3805
Guido van Rossumf8402962008-08-20 15:01:50 +00003806- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3807 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3808 extensions do not automatically benefit from the class attribute
3809 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3810 to their tp_flags field if they care. This is a backwards
3811 compatibility feature; in 3.0, all types will use the cache by
3812 default.
3813
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003814- Keyword arguments can now follow starred arguments. (``f(a, *args,
3815 keyword=23)`` is now valid syntax.)
3816
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003817- ctypes function pointers that are COM methods have a boolean True
3818 value again.
3819
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003820- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3821 by denying s# to parse objects that have a releasebuffer procedure,
3822 and introducing s*.
3823
Georg Brandl1e13ea92008-08-11 09:07:59 +00003824- Issue #3537: Fix an assertion failure when an empty but presized dict
3825 object was stored in the freelist.
3826
Mark Dickinsonb6467572008-08-04 21:30:09 +00003827- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3828 ValueError consistently across platforms.
3829
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003830- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3831 (64bit Unix, for example), unichr() would truncate its argument and return
3832 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3833
Neal Norwitze7d8be82008-07-31 17:17:14 +00003834- Apply security patches from Apple.
3835
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003836- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3837 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3838
Antoine Pitrou92f82162008-07-25 22:22:08 +00003839- Issue #1819: function calls with several named parameters are now on
3840 average 35% faster (as measured by pybench).
3841
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003842- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3843 the python debugger steps into a class statement: the free variables (local
3844 variables defined in an outer scope) would be deleted from the outer scope.
3845
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003846- Issue #2620: Overflow checking when allocating or reallocating memory
3847 was not always being done properly in some python types and extension
3848 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3849 all been updated to perform better checks and places in the code that
3850 would previously leak memory on the error path when such an allocation
3851 failed have been fixed.
3852
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003853Library
3854-------
3855
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003856- Issue #3612: Added some missing basic types in ctypes.wintypes.
3857
Benjamin Petersone977ad42008-08-20 01:42:01 +00003858- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3859 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3860
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003861- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3862 version reported by these tools does not necessarily follow the python
3863 version numbering scheme, so the module is less strict when parsing it.
3864
Nick Coghlanf70385a2008-08-18 12:42:46 +00003865- Issue #2235: Added Py3k warnings for types which will become unhashable
3866 under the stricter __hash__ inheritance rules in 3.0. Several types
3867 which did not meet the rules for hash invariants and were already
3868 unhashable in 3.0 have now been explicitly flagged as unhashable in
3869 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3870 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3871
Brett Cannon88f801d2008-08-18 00:46:22 +00003872- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3873 imported into the module but exposed as part of the module's API.
3874
Brett Cannon7b96f072008-08-18 00:41:11 +00003875- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3876
Brett Cannon46225e72008-08-18 00:36:52 +00003877- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3880
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003881- Issue #3575: Incremental decoder's decode function now takes bytearray
3882 by using 's*' instead of 't#'.
3883
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003884- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003885 fails unicode conversion on 2nd parameter. (windows only)
3886
Georg Brandl222e2082010-08-01 22:27:39 +00003887- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003888 in a redirect.
3889
Brett Cannonabe423e2008-08-16 21:47:07 +00003890- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003891 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003892
Facundo Batistaeb90b782008-08-16 14:44:07 +00003893- Issue #2776: fixed small issue when handling an URL with double slash
3894 after a 302 response in the case of not going through a proxy.
3895
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003896- Issue #2676: in the email package, content-type parsing was hanging on
3897 pathological input because of quadratic or exponential behaviour of a
3898 regular expression.
3899
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003900- Issue #3476: binary buffered reading through the new "io" library is now
3901 thread-safe.
3902
Brett Cannonbf3157b2008-08-14 05:00:03 +00003903- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3904 since mimetools itself is deprecated. Because modules are cached, all
3905 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3906
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003907- Issue #3134: shutil referenced undefined WindowsError symbol.
3908
Robert Schuppenies14646332008-08-10 11:01:53 +00003909- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3910 menu entries were not deleted.
3911
Brett Cannon83e81842008-08-09 23:30:55 +00003912- Copied the implementation of reduce() to _functools.reduce() to have a
3913 version that did not raise a DeprecationWarning under -3.
3914
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003915- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3916 a MemoryError rather than silently stop the iteration.
3917
Guido van Rossum59ce9012008-08-09 14:55:34 +00003918- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3919 to _sre.compile() will now be rejected. This should not affect anybody
3920 since the re.compile() function never generates invalid re-bytecode.
3921
Skip Montanaroa032bf42008-08-08 22:52:51 +00003922- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3923 upon first access it can be automatically initialized from the csv file if
3924 it wasn't initialized during instantiation.
3925
Brett Cannon3aa2a492008-08-06 22:28:09 +00003926- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3927 the reload() built-in has been removed.
3928
Brett Cannon7e30b672008-08-04 21:52:25 +00003929- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003930 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003941 asking for a specific length. This problem only affected files opened
3942 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003943

3951
Georg Brandlf9efabb2008-07-23 15:16:45 +00003952- Deprecate the "ast" parser function aliases.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003967- Issue #3394: zipfile.writestr sets external attributes when passed a
3968 file name rather than a ZipInfo instance, so files are extracted with
3969 mode 0600 rather than 000 under Unix.
3970
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003971- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3972 argument in python 2.5, this broke code that subclassed Popen to include its

3984 interaction with the tp_hash slot (added in 2.6b2) are now documented
3985
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003986- Issue #643841: The language reference now provides more detailed
3987 coverage of the lookup process for special methods. The disclaimers
3988 regarding lack of coverage of new-style classes have also been
3989 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003992What's New in Python 2.6 beta 2?
3993================================
3994
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003995*Release date: 17-Jul-2008*
3996
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003997Core and Builtins
3998-----------------
3999
Georg Brandl3e483f62008-07-16 22:57:41 +00004000- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4001 its methods now allow for items objects that can be converted to
4002 an integer using operator.index().
4003
Mark Dickinson64b7e502008-07-16 09:40:03 +00004004- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4005 produced a ValueError instead of giving the correct float.
4006
Eric Smitha5fa5a22008-07-16 00:11:49 +00004007- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4008 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4009
Mark Dickinson7103aa42008-07-15 19:08:33 +00004010- Issue #3008: the float type has a new instance method 'float.hex'
4011 and a new class method 'float.fromhex' to convert floating-point
4012 numbers to and from hexadecimal strings, respectively.
4013
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004014- Issue #2235: __hash__ is once again inherited by default. To allow
4015 collections.Hashable to remain meaningful in the presence of the
4016 default hash implementation (object.__hash__), it is now possible
4017 to explicit block inheritance of hash by setting __hash__=None at
4018 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4019 level.
4020
Nick Coghlanb028f502008-07-13 14:52:36 +00004021- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4022 the parent module cannot be found while performing an absolute import.
4023 This means that an incorrectly defined __package__ attribute will
4024 now only prevent relative imports in that module rather than causing
4025 all imports from that module to fail.
4026
Nick Coghlan14ff9942008-07-08 14:21:42 +00004027- Issue #2517: Allow unicode messages in Exceptions again by correctly
4028 bypassing the instance dictionary when looking up __unicode__ on
4029 new-style classes.
4030
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004031- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4032 set to a custom object whose write() method happens to install
4033 another file in sys.stdout.
4034
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004035- Issue #3088: Corrected a race condition in classes derived from
4036 threading.local: the first member set by a thread could be saved in
4037 another thread's dictionary.
4038
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004039- Issue #3004: Minor change to slice.indices(): the start and stop
4040 arguments are now treated identically, making the behaviour easier
4041 to describe and understand. For example, slice(None, -10,
4042 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4043 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4044 10, -1).
4045
Georg Brandl278fc502008-07-19 12:46:12 +00004046- Issue #3219: Calling a function with repeated keyword arguments,
4047 f(a=2, a=23), would not cause a syntax error. This was a regression
4048 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004049
Georg Brandl278fc502008-07-19 12:46:12 +00004050- Issue #2862: Make int and float freelist management consistent with
4051 other freelists. Changes their CompactFreeList apis into
4052 ClearFreeList apis and calls them via gc.collect().

4056
Thomas Heller57adf222008-08-14 19:10:48 +00004057- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4058 api functions without holding the GIL, which could lead to a fatal
4059 error when they failed.
4060
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004061- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4070 ForkingPickler.register() to resolve conflict with ctypes.
4071
Vinay Sajip51e65192008-07-18 09:01:10 +00004072- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004073
Thomas Heller880f5292008-07-15 19:39:38 +00004074- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4075 a valid dlerror() message.
4076
Thomas Heller2bad6572008-07-15 17:19:50 +00004077- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4078 incomplete structure was created.

4083
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004084- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004085
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004086- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4087 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004088 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004089 content-length. The problem had been corrected in the 2.4 branch, but never
4090 merged into trunk.
4091
Georg Brandle78fbcc2008-07-05 10:13:36 +00004092- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00004104
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004105- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4106 handling is now the same as that of other special attributes like __name__).
4107
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004108- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4109 removal in Python 3.0 in favor of urllib2.urlopen().

4561 original Python code has been kept as backup). This will allow for
4562 using the 'warning's machinery in such places as the parser where
4563 use of pure Python code is not possible. Both the ``showarning()``
4564 and ``formatwarning()`` gain an optional 'line' argument which is
4565 not called by default for backwards-compatibility reasons. Setting
4566 ``warnings.showwarning()`` to an implementation that lacks support
4567 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004630- Issue #2550: The approach used by client/server code for obtaining
4631 ports to listen on in network-oriented tests has been refined in an
4632 effort to facilitate running multiple instances of the entire
4633 regression test suite in parallel without issue.
4634 test_support.bind_port() has been fixed such that it will always
4635 return a unique port -- which wasn't always the case with the
4636 previous implementation, especially if socket options had been set
4637 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4638 new implementation of bind_port() will actually raise an exception
4639 if it is passed an AF_INET/SOCK_STREAM socket with either the
4640 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4641 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4642 the socket it's been passed. This currently only applies to
4643 Windows. This option prevents any other sockets from binding to the
4644 host/port we've bound to, thus removing the possibility of the
4645 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4646 when a second SOCK_STREAM socket binds and accepts to a host/port
4647 that's already been bound by another socket. The optional preferred
4648 port parameter to bind_port() has been removed. Under no
4649 circumstances should tests be hard coding ports!
4650
4651 test_support.find_unused_port() has also been introduced, which will
4652 pass a temporary socket object to bind_port() in order to obtain an
4653 unused port. The temporary socket object is then closed and
4654 deleted, and the port is returned. This method should only be used
4655 for obtaining an unused port in order to pass to an external program
4656 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4657 a parameter to a server-oriented class that doesn't give you direct
4658 access to the underlying socket used.
4659
4660 Finally, test_support.HOST has been introduced, which should be used
4661 for the host argument of any relevant socket calls (i.e. bind and
4662 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004663
4664 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004665 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004666 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4667 test_asynchat and test_socket_ssl.
4668
Georg Brandl3ee81df2008-05-17 18:14:43 +00004669 It is now possible for multiple instances of the regression test
4670 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004949- Added the future_builtins module, which contains hex() and oct().
4950 These are the PEP 3127 version of these functions, designed to be
4951 compatible with the hex() and oct() builtins from Python 3.0. They
4952 differ slightly in their output formats from the existing, unchanged
4953 Python 2.6 builtins. The expected usage of the future_builtins
4954 module is:
4955 from future_builtins import hex, oct
4956
Eric Smith7ef40bf2008-02-20 23:34:22 +00004957- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4958 exponents for exponents with absolute value < 100. Follows C99
4959 standard. This is a change on Windows, which would use 3 digits.
4960 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4961 so that any alterations it does to the resulting string will be
4962 available in stringlib/formatter.h (for float.__format__).
4963
Eric Smith5a3c1352008-02-19 13:21:56 +00004964- Implemented PEP 3101, Advanced String Formatting. This adds a new
4965 builtin format(); a format() method for str and unicode; a
4966 __format__() method to object, str, unicode, int, long, float, and
4967 datetime; the class string.Formatter; and the C API
4968 PyObject_Format().
4969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Fixed several potential crashes, all caused by specially crafted
4971 __del__ methods exploiting objects in temporarily inconsistent
4972 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004973
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004974- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975 prevent a possible crash: an Abstract Base Class would try to access
4976 a slot on a registered virtual subclass.

4982 in order to allow pymalloc to free more arenas. Python may give back
4983 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004984
Georg Brandl3ee81df2008-05-17 18:14:43 +00004985- Issue #2045: Fix an infinite recursion triggered when printing a
4986 subclass of collections.defaultdict, if its default_factory is set
4987 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004988
Christian Heimesf75dbef2008-02-08 00:11:31 +00004989- Fixed a minor memory leak in dictobject.c. The content of the free
4990 list was not freed on interpreter shutdown.
4991
Georg Brandl21e99f42010-03-07 15:23:59 +00004992- Limit free list of method and built-in function objects to 256

4996 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004997 to compact the internal free lists of pre-allocted ints and floats.
4998
Georg Brandl3ee81df2008-05-17 18:14:43 +00004999- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5000 calls. Python expected the return type int but the fork familie
5001 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005015- Patch #1473257: generator objects gain a gi_code attribute. This is
5016 the same object as the func_code attribute of the function that
5017 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005018
Georg Brandl3ee81df2008-05-17 18:14:43 +00005019- Issue #1920: "while 0" statements were completely removed by the
5020 compiler, even in the presence of an "else" clause, which is
5021 supposed to be run when the condition is false. Now the compiler
5022 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005023
Guido van Rossumeead05f2008-01-24 18:21:02 +00005024- A few crashers fixed: weakref_in_del.py (issue #1377858);

5031
Georg Brandl3ee81df2008-05-17 18:14:43 +00005032- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005033 several extension methods and modules do not work without unicode
5034 support.
5035

5040
Georg Brandl6caad7d2008-01-26 14:19:22 +00005041- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005042 added.
5043
Christian Heimesc94e2b52008-01-14 04:13:37 +00005044- sys.float_info / PyFloat_GetInfo: The floating point information
5045 object was converted from a dict to a specialized structseq object.
5046
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047- Patch #1816: Added sys.flags structseq. It exposes the status of
5048 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005049
Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Patch #1700288: added a type attribute cache that caches method
5055 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005056
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005057- Bug #1776: __import__() no longer accepts filenames on any platform.
5058 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005060- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5061
Georg Brandl3ee81df2008-05-17 18:14:43 +00005062- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5063 envvar and sys.dont_write_bytecode attribute. All these can be set
5064 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005065
Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- Improve some exception messages when Windows fails to load an
5067 extension module. Now we get for example '%1 is not a valid Win32
5068 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005075- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005076 and INF. float("nan"), float("inf") and float("-inf") now work on
5077 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005079- Compiler now generates simpler and faster code for dictionary
5080 literals. The oparg for BUILD_MAP now indicates an estimated
5081 dictionary size. There is a new opcode, STORE_MAP, for adding
5082 entries to the dictionary.

5094
Nick Coghlanef01d822007-12-03 12:55:17 +00005095- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Patch #1739468: Directories and zipfiles containing a __main__.py
5112 file can now be directly executed by passing their name to the
5113 interpreter. The directory/zipfile is automatically inserted as the
5114 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- Issue #1265: Fix a problem with sys.settrace, if the tracing
5117 function uses a generator expression when at the same time the
5118 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005119
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005120- sets and frozensets now have an isdisjoint() method.
5121

5125
Georg Brandl21e99f42010-03-07 15:23:59 +00005126- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005127 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5128 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005129
Georg Brandl3ee81df2008-05-17 18:14:43 +00005130- Issue #1686386: Tuple's tp_repr did not take into account the
5131 possibility of having a self-referential tuple, which is possible
5132 from C code. Nor did object's tp_str consider that a type's tp_str
5133 could do something that could lead to an inifinite recursion.
5134 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5135 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- Issue #1164: It was possible to trigger deadlock when using the
5138 'print' statement to write to a file since the GIL was not released
5139 as needed. Now PyObject_Print() does the right thing along with
5140 various tp_print implementations of the built-in types and those in
5141 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005142
Georg Brandl3ee81df2008-05-17 18:14:43 +00005143- Issue #1147: Exceptions were directly allowing string exceptions in
5144 their throw() method even though string exceptions no longer
5145 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005146
Georg Brandl3ee81df2008-05-17 18:14:43 +00005147- Issue #1096: Prevent a segfault from getting the repr of a very
5148 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005149
Brett Cannon1e534b52007-09-07 04:18:30 +00005150- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005151 PyObject_Call() never calling back out to Python code to trigger
5152 recursion depth updates/checks. Required the creation of a static
5153 RuntimeError instance in case normalizing an exception put the
5154 recursion check value past its limit. Fixes crashers
5155 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005156
Georg Brandl3ee81df2008-05-17 18:14:43 +00005157- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005170- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005171 __*__ attributes. (Some already existed, e.g., __doc__ and
5172 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005173
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005174- Add -3 option to the interpreter to warn about features that are
5175 deprecated and will be changed/removed in Python 3.0.
5176
Georg Brandl2134e752007-05-21 20:34:16 +00005177- Patch #1686487: you can now pass any mapping after '**' in function
5178 calls.
5179
Collin Winter62903052007-05-18 23:11:24 +00005180- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005181 "except E as target:". This is to provide forwards compatibility
5182 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005183
Brett Cannon229cee22007-05-05 01:34:02 +00005184- Deprecate BaseException.message as per PEP 352.
5185
Georg Brandl3ee81df2008-05-17 18:14:43 +00005186- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005187 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005188
Vinay Sajip8549ce32007-05-06 17:53:37 +00005189- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005190 setting a plain string, ie don't expand to single letter identifiers.
5191
Raymond Hettinger13936692007-04-11 18:40:58 +00005192- Request #1191699: Slices can now be pickled.
5193
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005194- Request #1193128: str.translate() now allows a None argument for
5195 translations that only remove characters without re-mapping the
5196 remaining characters.
5197
Georg Brandl5cb76c12007-03-21 09:00:39 +00005198- Patch #1682205: a TypeError while unpacking an iterable is no longer
5199 masked by a generic one with the message "unpack non-sequence".
5200
Neal Norwitzaa754b72007-03-21 06:39:48 +00005201- Remove unused file Python/fmod.c.
5202
Guido van Rossum143b5642007-03-23 04:58:42 +00005203- Bug #1683368: The object.__init__() and object.__new__() methods are
5204 now stricter in rejecting excess arguments. The only time when
5205 either allows excess arguments is when it is not overridden and the
5206 other one is. For backwards compatibility, when both are
5207 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005208 warning later). Also, type.__init__() insists on the same signature
5209 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005210
Georg Brandl3ee81df2008-05-17 18:14:43 +00005211- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5212 object to complex using its __complex__() method before falling back
5213 to the __float__() method. Therefore, the functions in the cmath
5214 module now can operate on objects that define a __complex__()
5215 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005216
Georg Brandl3ee81df2008-05-17 18:14:43 +00005217- Patch #1623563: allow __class__ assignment for classes with
5218 __slots__. The old and the new class are still required to have the
5219 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005220
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221- Patch #1642547: Fix an error/crash when encountering syntax errors

5225 ``object.__reduce_ex__()`` is called with an object that is faking
5226 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005227
Georg Brandl3ee81df2008-05-17 18:14:43 +00005228- Patch #1680015: Don't modify __slots__ tuple if it contains an

5232
Georg Brandl7b9c5552007-03-12 14:30:05 +00005233- Bug #1678647: write a newline after printing an exception in any
5234 case, even when converting the value to a string failed.
5235
Georg Brandl871f1bc2007-03-12 13:17:36 +00005236- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237 its argument, if it exists. If not, it will work like before. This
5238 allows customizing the output of dir() in the presence of a
5239 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005240
Collin Winter276887b2007-03-12 16:11:39 +00005241- Patch #922167: Python no longer segfaults when faced with infinitely
5242 self-recursive reload() calls (as reported by bug #742342).
5243
Georg Brandl3ee81df2008-05-17 18:14:43 +00005244- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Patch #1491866: change the complex() constructor to allow
5248 parthensized forms. This means complex(repr(x)) now works instead of
5249 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005250
Georg Brandlaa2321b2007-03-07 00:40:28 +00005251- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005252 makes the filenames the warning module prints much more sensible
5253 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005254
Georg Brandl49aafc92007-03-07 00:34:46 +00005255- Variant of patch #697613: don't exit the interpreter on a SystemExit
5256 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005257 variable is given, but break into the interactive interpreter just
5258 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005266- Patch #1674228: when assigning a slice (old-style), check for the
5267 sq_ass_slice instead of the sq_slice slot.
5268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- When printing an unraisable error, don't print exceptions. before
5270 the name. This duplicates the behavior whening normally printing
5271 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005804 AttributeError instead of an IOError when the server's response
5805 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005806

Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Patch #1429539: pdb now correctly initializes the __main__ module
5812 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005813 correctly now.
5814

5821
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- Patch #1530482: add pydoc.render_doc() which returns the

5837
Georg Brandl92a6bae2007-03-13 17:43:32 +00005838- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005839 are set for invalid interpolation sequences that would lead to
5840 errors on reading back those values.

5881

5883 returned string up to the first NUL character.

5894
Georg Brandl3ee81df2008-05-17 18:14:43 +00005895- unittest now verifies more of its assumptions. In particular,
5896 TestCase and TestSuite subclasses (not instances) are no longer
5897 accepted in TestSuite.addTest(). This should cause no
5898 incompatibility since it never made sense with ordinary subclasses
5899 -- the failure just occurred later, with a more cumbersome
5900 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006187 that the SMTP.starttls() caller no longer needs to call ehlo()

6271 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006288- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289 time so that opening a database previously created with the DB_DUP
6290 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6291 opens. Specifically: dictionary assignment to a DB object will
6292 replace all values for a given key when the database allows
6293 duplicate values. DB users should use DB.put(k, v) when they want
6294 to store duplicates; not DB[k] = v.

6301 characters with ASCII value less than 32. Also, it correctly quotes
6302 dots only if they occur on a single line, as opposed to the previous
6303 behavior of quoting dots if they are the second character of any
6304 line.

6650 of w# format code incorrectly truncated the length to an int, even
6651 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6652 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006682- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6683 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
