148 fix various SSLSocket methods to raise socket.error rather than an
149 unhelpful TypeError when called on an unconnected socket. Original patch
150 by Andrew Bennetts.
151
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000152- Issue #9826: OrderedDict.__repr__ can now handle self-referential

161 This prevents user-created self-referencing ordered dictionaries from
162 becoming permanently uncollectable GC garbage. The downside is that
163 removing __del__ means that the internal doubly-linked list has to wait for
164 GC collection rather than freeing memory immediately when the refcnt drops
165 to zero.
166
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000167- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000168 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000169 value.
170
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000171- Issue #9792: In case of connection failure, socket.create_connection()
172 would swallow the exception and raise a new one, making it impossible
173 to fetch the original errno, or to filter timeout errors. Now the
174 original error is re-raised.
175
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000176- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
177 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
178 be updated back after the system call. Original patch by Brian Brazil.
179
Antoine Pitroudca9de92010-09-04 17:52:26 +0000180- Issue #1100562: Fix deep-copying of objects derived from the list and
181 dict types. Patch by Michele Orrù and Björn Lindqvist.
182
Fred Drakea1e627d2010-09-03 03:55:50 +0000183- Issue #7005: Fixed output of None values for RawConfigParser.write and
184 ConfigParser.write.
185
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000186- Issue #808164: Fixed socket.close to avoid references to globals, to
187 avoid issues when socket.close is called from a __del__ method.
188
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000189- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
190 falling into recursion.
191
R. David Murray7c4bf552010-08-25 01:45:57 +0000192- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
193 character years even if the message contains RFC822 two character years.
194
Daniel Stutzbach91287322010-08-24 21:09:30 +0000195- Issue #8750: Fixed MutableSet's methods to correctly handle
196 reflexive operations, namely x -= x and x ^= x.
197
Victor Stinnercaafd772010-09-08 10:51:01 +0000198- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

207 module now correctly return a set. (Patch by Eli Bendersky.)
208
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000209- Issue #9617: Signals received during a low-level write operation aren't
210 ignored by the buffered IO layer anymore.
211
Benjamin Peterson52c36052010-08-21 03:03:22 +0000212- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
213 are not held onto after they are deleted elsewhere.
214
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000215- Issue #9626: the view methods for collections.OrderedDict() were returning
216 the unordered versions inherited from dict. Those methods are now
217 overridden to provide ordered views.
218
Éric Araujo0389ae62010-08-14 03:07:46 +0000219- Issue #8688: MANIFEST files created by distutils now include a magic
220 comment indicating they are generated. Manually maintained MANIFESTs
221 without this marker will not be overwritten or removed.
222
Antoine Pitroue1436d12010-08-12 15:25:51 +0000223- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

236 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
237
Antoine Pitrou99009162010-08-09 22:51:24 +0000238- Issue #3757: thread-local objects now support cyclic garbage collection.

618
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000619- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
620 start byte and the continuation byte(s) are now considered invalid, instead
621 of the number of bytes specified by the start byte.
622 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
623 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
624 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
625 Previous versions returned a single u'\ufffd'.
626
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000627- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000628 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
629 arises from the "Overriding __eq__ blocks inheritance ..." warning
630 when turned into an exception: in this case the exception simply
631 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000632
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000633- Issue #8748: Fix two issues with comparisons between complex and integer
634 objects. (1) The comparison could incorrectly return True in some cases
635 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
636 (2) The comparison raised an OverflowError for large integers, leading
637 to unpredictable exceptions when combining integers and complex objects
638 in sets or dicts.
639
Mark Dickinson81336372010-05-30 12:12:25 +0000640- Issue #5211: Implicit coercion for the complex type is now completely
641 removed. (Coercion for arithmetic operations was already removed in 2.7
642 alpha 4, but coercion for rich comparisons was accidentally left in.)
643
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000644- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
645 and error handler, instead of writing to the C stderr file in utf-8
646
Georg Brandlfee0f442010-05-22 21:26:21 +0000647- Issue #7902: When using explicit relative import syntax, don't try implicit
648 relative import semantics.

Georg Brandlfee0f442010-05-22 21:26:21 +0000659- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
660 of the interpreter to set sys.argv without also modifying sys.path. This
661 helps fix `CVE-2008-5983

686
R. David Murray52dcd452010-06-02 22:03:15 +0000687- Issue #1368247: set_charset (and therefore MIMEText) now automatically

Georg Brandlfee0f442010-05-22 21:26:21 +0000879- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
880 the method could block indefinitely if called just before the event loop
881 started running. This also fixes the occasional freezes witnessed in
882 test_httpservers.
Antoine Pitroua6240402010-04-25 21:40:32 +0000883
Antoine Pitroufc69af12010-04-24 20:04:58 +0000884- Issue #5103: SSL handshake would ignore the socket timeout and block
885 indefinitely if the other end didn't respond.
886
Georg Brandlfee0f442010-05-22 21:26:21 +0000887- The do_handshake() method of SSL objects now adjusts the blocking mode of the
888 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +0000933 filename and date, conforming to the 'standards' they were originally designed
934 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000980 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

1004
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001005- Issue #7301: Add environment variable $PYTHONWARNINGS.
1006
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001007- Issue #8329: Don't return the same lists from select.select when no fds are
1008 changed.
1009
Georg Brandlfee0f442010-05-22 21:26:21 +00001010- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001011 on 64-bit machines. The shift count for either left or right shift is
1012 permitted to be up to sys.maxsize.
1013
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001014- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00001020- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1021 with a non-empty format string. This is an effort to future-proof user
1022 code. If a derived class does not currently implement __format__ but later
1023 adds its own __format__, it would most likely break user code that had
1024 supplied a format string. This will be changed to a DeprecationWaring in
1025 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001026
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001027- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlfee0f442010-05-22 21:26:21 +00001058- Issue #8257: The Decimal construct now accepts a float instance directly,
1059 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001060

1063
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001064- collections.Counter() now supports a subtract() method.
1065
Georg Brandlfee0f442010-05-22 21:26:21 +00001066- The functools module now has a total_ordering() class decorator to simplify
1067 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001068
Georg Brandlfee0f442010-05-22 21:26:21 +00001069- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +00001075- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1076 InvalidOperation instead of returning False. (Comparisons involving a quiet
1077 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1078 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001079
Georg Brandlfee0f442010-05-22 21:26:21 +00001080- Issue #2531: Comparison operations between floats and Decimal instances now
1081 return a result based on the numeric values of the operands; previously they
1082 returned an arbitrary result based on the relative ordering of id(float) and
1083 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001084
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001085- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001086 argument `-` which tells it to read files to compile from stdin. Each line is
1087 read on demand and the named file is compiled immediately. (Original patch by

1094 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001095 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001097- Comparisons using one of <, <=, >, >= between a complex instance and a
1098 Fractions instance now raise TypeError instead of returning True/False. This
1099 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1100 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001514 file position when calling `truncate()`. It would previously change the file
1515 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001516 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1519 class used to represent files stored inside an archive. The new
1520 implementation is significantly faster and can be wrapped in a

1522 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1611-----------------
1612
Georg Brandlba83f822010-03-14 09:50:54 +00001613- The ``__complex__()`` method is now looked up on the class of instances to
1614 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001615
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001616- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1617 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1618
Mark Dickinson1b34d252010-01-01 17:27:30 +00001619- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001620 DeprecationWarning when passed a float argument where an integer was expected.
1621 These functions and methods now raise TypeError instead. The majority of the
1622 effects of this change are in the extension modules, but some core functions
1623 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1624 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001625

1635 used to drop the time part of the result.
1636
Georg Brandlba83f822010-03-14 09:50:54 +00001637- Issue #1811: Improve accuracy and cross-platform consistency for true division
1638 of integers: the result of a/b is now correctly rounded for ints a and b (at
1639 least on IEEE 754 platforms), and in particular does not depend on the
1640 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001641
Georg Brandlba83f822010-03-14 09:50:54 +00001642- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1643 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1644 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001647 executables on OSX.
1648
Georg Brandlba83f822010-03-14 09:50:54 +00001649 These executables now work properly with the arch(1) command: ``arch -ppc
1650 python`` will start a universal binary version of python in PPC mode (unlike
1651 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001674 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

1738 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

Georg Brandlba83f822010-03-14 09:50:54 +00001822 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1823 providing correctly-rounded strtod and dtoa C functions. This code is
1824 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1825 the C compiler. There may be a small number of platforms on which correct
1826 operation of this code cannot be guaranteed, so the code is not used: notably,
1827 this applies to platforms where the C double format is not IEEE 754 binary64,
1828 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1829 and Python's configure script is unable to determine how to change the FPU
1830 precision. On these platforms conversions use the platform strtod and dtoa,
1831 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001833- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1834 uses the correctly-rounded string <-> float conversions described above (when
1835 available), and so produces correctly rounded results that will display nicely
1836 under the float repr. There are two related small changes: (1) round now
1837 accepts any class with an ``__index__()`` method for its second argument (but
1838 no longer accepts floats for the second argument), and (2) an excessively
1839 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1840 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002057- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002058 untrackable objects are not tracked by the garbage collector. This can reduce
2059 the size of collections and therefore the garbage collection overhead on
2060 long-running programs, depending on their particular use of datatypes.

2101
Georg Brandl29c6a282009-04-05 20:23:13 +00002102- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002103 were suppressing all exceptions. These include list(), filter(), map(),

2132
Georg Brandlba83f822010-03-14 09:50:54 +00002133- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2134 existing .py counterpart, override the co_filename attributes of all code
2135 objects if the original filename is obsolete (which can happen if the file has
2136 been renamed, moved, or if it is accessed through different paths). Patch by

2190
Georg Brandlba83f822010-03-14 09:50:54 +00002191- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2192 file objects with closefd=False. The file descriptor is still kept open but
2193 the file object behaves like a closed file. The ``FileIO`` object also got a
2194 new readonly attribute ``closefd``.

2213
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002214- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002215 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002217- On windows, ``os.chdir()`` given unicode was not working if
2218 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2219 this code path is really executed because I cannot move to such directory on
2220 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002222- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2223 element is temporarily replaced with an equivalent frozenset. But the
2224 eventual KeyError would always report the empty ``frozenset()`` as the missing
2225 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002245- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2246 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2247 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2248 of using the replace error handler in PyUnicode_DecodeUTF8().
2249
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002250- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002253- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2255 gives improved memory leak detection when running under Valgrind, while taking
2256 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003417 - Packing a float now always gives a Deprecation Warning. Previously it
3418 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003419
Georg Brandlba83f822010-03-14 09:50:54 +00003420 - If x is not an int, long or float, then packing x will always result in
3421 struct.error. Previously an x with an __int__ method could be packed by
3422 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3423 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3424 neither __int__ nor __long__, TypeError used to be raised (with a
3425 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3426 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003427
Georg Brandlba83f822010-03-14 09:50:54 +00003428 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3429 argument with an __int__ method can be packed, but use of this feature
3430 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003623- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3624 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3625 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3626 ``printf`` function, whereas PyString_FromFormat has an independent
3627 implementation and uses "%zd" on all platforms for size_t values.
3628 This makes a difference on win64, where ``printf`` needs "%Id" to display
3629 64bit values.

Nick Coghland2e09382008-09-11 12:11:06 +00003697- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003698 return a list or None rather than a custom object.
3699
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003700- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003724 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3725 for catch_warnings() also led to an improvement in the raising of a
3726 DeprecationWarning related to warnings.warn_explicit().
3727
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003728- The deprecation warnings for the old camelCase threading API were removed.

3750
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003751- Issue #2975: When compiling several extension modules with Visual Studio 2008
3752 from the same python interpreter, some environment variables would grow
3753 without limit.
3754
Benjamin Peterson37346b22008-08-23 20:27:43 +00003755- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3756 exploitation of poor argument checking.
3757
Gerhard Häringef2276b2008-09-12 13:54:06 +00003758- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3759
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003760- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3761 remaining ones have "pysqlite_" prefix.
3762
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003763- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3771 wrapper for warnings.catch_warnings() that makes it easier to check
3772 that expected warning messages are being reported.
3773

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003792What's New in Python 2.6 beta 3?
3793================================
3794
Barry Warsaw07a4a382008-08-21 01:15:08 +00003795*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003796
3797Core and Builtins
3798-----------------
3799
Guido van Rossumf8402962008-08-20 15:01:50 +00003800- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3801 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3802 extensions do not automatically benefit from the class attribute
3803 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3804 to their tp_flags field if they care. This is a backwards
3805 compatibility feature; in 3.0, all types will use the cache by
3806 default.
3807
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003808- Keyword arguments can now follow starred arguments. (``f(a, *args,
3809 keyword=23)`` is now valid syntax.)
3810
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003811- ctypes function pointers that are COM methods have a boolean True
3812 value again.
3813
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003814- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3815 by denying s# to parse objects that have a releasebuffer procedure,
3816 and introducing s*.
3817
Georg Brandl1e13ea92008-08-11 09:07:59 +00003818- Issue #3537: Fix an assertion failure when an empty but presized dict
3819 object was stored in the freelist.
3820
Mark Dickinsonb6467572008-08-04 21:30:09 +00003821- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3822 ValueError consistently across platforms.
3823
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003824- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3825 (64bit Unix, for example), unichr() would truncate its argument and return
3826 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3827
Neal Norwitze7d8be82008-07-31 17:17:14 +00003828- Apply security patches from Apple.
3829
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003830- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3831 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3832
Antoine Pitrou92f82162008-07-25 22:22:08 +00003833- Issue #1819: function calls with several named parameters are now on
3834 average 35% faster (as measured by pybench).
3835
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003836- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3837 the python debugger steps into a class statement: the free variables (local
3838 variables defined in an outer scope) would be deleted from the outer scope.
3839
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003840- Issue #2620: Overflow checking when allocating or reallocating memory
3841 was not always being done properly in some python types and extension
3842 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3843 all been updated to perform better checks and places in the code that
3844 would previously leak memory on the error path when such an allocation
3845 failed have been fixed.
3846

3848-------
3849
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003850- Issue #3612: Added some missing basic types in ctypes.wintypes.
3851
Benjamin Petersone977ad42008-08-20 01:42:01 +00003852- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3853 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3854
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003855- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3856 version reported by these tools does not necessarily follow the python
3857 version numbering scheme, so the module is less strict when parsing it.
3858
Nick Coghlanf70385a2008-08-18 12:42:46 +00003859- Issue #2235: Added Py3k warnings for types which will become unhashable
3860 under the stricter __hash__ inheritance rules in 3.0. Several types
3861 which did not meet the rules for hash invariants and were already
3862 unhashable in 3.0 have now been explicitly flagged as unhashable in
3863 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3864 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3865
Brett Cannon88f801d2008-08-18 00:46:22 +00003866- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3867 imported into the module but exposed as part of the module's API.
3868
Brett Cannon7b96f072008-08-18 00:41:11 +00003869- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3870
Brett Cannon46225e72008-08-18 00:36:52 +00003871- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003873- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3874
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003875- Issue #3575: Incremental decoder's decode function now takes bytearray
3876 by using 's*' instead of 't#'.
3877
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003878- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003879 fails unicode conversion on 2nd parameter. (windows only)
3880
Georg Brandl222e2082010-08-01 22:27:39 +00003881- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003882 in a redirect.
3883
Brett Cannonabe423e2008-08-16 21:47:07 +00003884- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003885 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003886
Facundo Batistaeb90b782008-08-16 14:44:07 +00003887- Issue #2776: fixed small issue when handling an URL with double slash
3888 after a 302 response in the case of not going through a proxy.
3889
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003890- Issue #2676: in the email package, content-type parsing was hanging on
3891 pathological input because of quadratic or exponential behaviour of a
3892 regular expression.
3893
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003894- Issue #3476: binary buffered reading through the new "io" library is now
3895 thread-safe.
3896
Brett Cannonbf3157b2008-08-14 05:00:03 +00003897- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3898 since mimetools itself is deprecated. Because modules are cached, all
3899 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3900
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003901- Issue #3134: shutil referenced undefined WindowsError symbol.
3902
Robert Schuppenies14646332008-08-10 11:01:53 +00003903- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3904 menu entries were not deleted.
3905
Brett Cannon83e81842008-08-09 23:30:55 +00003906- Copied the implementation of reduce() to _functools.reduce() to have a
3907 version that did not raise a DeprecationWarning under -3.
3908
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003909- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3910 a MemoryError rather than silently stop the iteration.
3911
Guido van Rossum59ce9012008-08-09 14:55:34 +00003912- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3913 to _sre.compile() will now be rejected. This should not affect anybody
3914 since the re.compile() function never generates invalid re-bytecode.
3915
Skip Montanaroa032bf42008-08-08 22:52:51 +00003916- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3917 upon first access it can be automatically initialized from the csv file if
3918 it wasn't initialized during instantiation.
3919
Brett Cannon3aa2a492008-08-06 22:28:09 +00003920- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3921 the reload() built-in has been removed.
3922
Brett Cannon7e30b672008-08-04 21:52:25 +00003923- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003924 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003935 asking for a specific length. This problem only affected files opened
3936 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003937

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003961- Issue #3394: zipfile.writestr sets external attributes when passed a
3962 file name rather than a ZipInfo instance, so files are extracted with
3963 mode 0600 rather than 000 under Unix.
3964
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003965- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3966 argument in python 2.5, this broke code that subclassed Popen to include its

3978 interaction with the tp_hash slot (added in 2.6b2) are now documented
3979
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003980- Issue #643841: The language reference now provides more detailed
3981 coverage of the lookup process for special methods. The disclaimers
3982 regarding lack of coverage of new-style classes have also been
3983 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003986What's New in Python 2.6 beta 2?
3987================================
3988
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003989*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003991Core and Builtins
3992-----------------
3993
Georg Brandl3e483f62008-07-16 22:57:41 +00003994- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3995 its methods now allow for items objects that can be converted to
3996 an integer using operator.index().
3997
Mark Dickinson64b7e502008-07-16 09:40:03 +00003998- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3999 produced a ValueError instead of giving the correct float.
4000
Eric Smitha5fa5a22008-07-16 00:11:49 +00004001- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4002 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4003
Mark Dickinson7103aa42008-07-15 19:08:33 +00004004- Issue #3008: the float type has a new instance method 'float.hex'
4005 and a new class method 'float.fromhex' to convert floating-point
4006 numbers to and from hexadecimal strings, respectively.
4007
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004008- Issue #2235: __hash__ is once again inherited by default. To allow
4009 collections.Hashable to remain meaningful in the presence of the
4010 default hash implementation (object.__hash__), it is now possible
4011 to explicit block inheritance of hash by setting __hash__=None at
4012 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4013 level.
4014
Nick Coghlanb028f502008-07-13 14:52:36 +00004015- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4016 the parent module cannot be found while performing an absolute import.
4017 This means that an incorrectly defined __package__ attribute will
4018 now only prevent relative imports in that module rather than causing
4019 all imports from that module to fail.
4020
Nick Coghlan14ff9942008-07-08 14:21:42 +00004021- Issue #2517: Allow unicode messages in Exceptions again by correctly
4022 bypassing the instance dictionary when looking up __unicode__ on
4023 new-style classes.
4024
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004025- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4026 set to a custom object whose write() method happens to install
4027 another file in sys.stdout.
4028
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004029- Issue #3088: Corrected a race condition in classes derived from
4030 threading.local: the first member set by a thread could be saved in
4031 another thread's dictionary.
4032
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004033- Issue #3004: Minor change to slice.indices(): the start and stop
4034 arguments are now treated identically, making the behaviour easier
4035 to describe and understand. For example, slice(None, -10,
4036 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4037 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4038 10, -1).
4039
Georg Brandl278fc502008-07-19 12:46:12 +00004040- Issue #3219: Calling a function with repeated keyword arguments,
4041 f(a=2, a=23), would not cause a syntax error. This was a regression
4042 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004043
Georg Brandl278fc502008-07-19 12:46:12 +00004044- Issue #2862: Make int and float freelist management consistent with
4045 other freelists. Changes their CompactFreeList apis into
4046 ClearFreeList apis and calls them via gc.collect().

4050
Thomas Heller57adf222008-08-14 19:10:48 +00004051- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4052 api functions without holding the GIL, which could lead to a fatal
4053 error when they failed.
4054
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004055- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4064 ForkingPickler.register() to resolve conflict with ctypes.
4065
Vinay Sajip51e65192008-07-18 09:01:10 +00004066- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004067
Thomas Heller880f5292008-07-15 19:39:38 +00004068- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4069 a valid dlerror() message.

Thomas Heller2bad6572008-07-15 17:19:50 +00004071- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4072 incomplete structure was created.

4077
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004078- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004079
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004080- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4081 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004082 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004083 content-length. The problem had been corrected in the 2.4 branch, but never
4084 merged into trunk.
4085
Georg Brandle78fbcc2008-07-05 10:13:36 +00004086- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004097 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004098
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004099- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4100 handling is now the same as that of other special attributes like __name__).
4101
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004102- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4103 removal in Python 3.0 in favor of urllib2.urlopen().

4555 original Python code has been kept as backup). This will allow for
4556 using the 'warning's machinery in such places as the parser where
4557 use of pure Python code is not possible. Both the ``showarning()``
4558 and ``formatwarning()`` gain an optional 'line' argument which is
4559 not called by default for backwards-compatibility reasons. Setting
4560 ``warnings.showwarning()`` to an implementation that lacks support
4561 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004624- Issue #2550: The approach used by client/server code for obtaining
4625 ports to listen on in network-oriented tests has been refined in an
4626 effort to facilitate running multiple instances of the entire
4627 regression test suite in parallel without issue.
4628 test_support.bind_port() has been fixed such that it will always
4629 return a unique port -- which wasn't always the case with the
4630 previous implementation, especially if socket options had been set
4631 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4632 new implementation of bind_port() will actually raise an exception
4633 if it is passed an AF_INET/SOCK_STREAM socket with either the
4634 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4635 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4636 the socket it's been passed. This currently only applies to
4637 Windows. This option prevents any other sockets from binding to the
4638 host/port we've bound to, thus removing the possibility of the
4639 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4640 when a second SOCK_STREAM socket binds and accepts to a host/port
4641 that's already been bound by another socket. The optional preferred
4642 port parameter to bind_port() has been removed. Under no
4643 circumstances should tests be hard coding ports!
4644
4645 test_support.find_unused_port() has also been introduced, which will
4646 pass a temporary socket object to bind_port() in order to obtain an
4647 unused port. The temporary socket object is then closed and
4648 deleted, and the port is returned. This method should only be used
4649 for obtaining an unused port in order to pass to an external program
4650 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4651 a parameter to a server-oriented class that doesn't give you direct
4652 access to the underlying socket used.
4653
4654 Finally, test_support.HOST has been introduced, which should be used
4655 for the host argument of any relevant socket calls (i.e. bind and
4656 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004657
4658 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004660 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4661 test_asynchat and test_socket_ssl.
4662
Georg Brandl3ee81df2008-05-17 18:14:43 +00004663 It is now possible for multiple instances of the regression test
4664 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004943- Added the future_builtins module, which contains hex() and oct().
4944 These are the PEP 3127 version of these functions, designed to be
4945 compatible with the hex() and oct() builtins from Python 3.0. They
4946 differ slightly in their output formats from the existing, unchanged
4947 Python 2.6 builtins. The expected usage of the future_builtins
4948 module is:
4949 from future_builtins import hex, oct
4950
Eric Smith7ef40bf2008-02-20 23:34:22 +00004951- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4952 exponents for exponents with absolute value < 100. Follows C99
4953 standard. This is a change on Windows, which would use 3 digits.
4954 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4955 so that any alterations it does to the resulting string will be
4956 available in stringlib/formatter.h (for float.__format__).
4957
Eric Smith5a3c1352008-02-19 13:21:56 +00004958- Implemented PEP 3101, Advanced String Formatting. This adds a new
4959 builtin format(); a format() method for str and unicode; a
4960 __format__() method to object, str, unicode, int, long, float, and
4961 datetime; the class string.Formatter; and the C API
4962 PyObject_Format().
4963
Georg Brandl3ee81df2008-05-17 18:14:43 +00004964- Fixed several potential crashes, all caused by specially crafted
4965 __del__ methods exploiting objects in temporarily inconsistent
4966 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004967
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004968- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004969 prevent a possible crash: an Abstract Base Class would try to access
4970 a slot on a registered virtual subclass.

4976 in order to allow pymalloc to free more arenas. Python may give back
4977 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004978
Georg Brandl3ee81df2008-05-17 18:14:43 +00004979- Issue #2045: Fix an infinite recursion triggered when printing a
4980 subclass of collections.defaultdict, if its default_factory is set
4981 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004982
Christian Heimesf75dbef2008-02-08 00:11:31 +00004983- Fixed a minor memory leak in dictobject.c. The content of the free
4984 list was not freed on interpreter shutdown.
4985
Georg Brandl21e99f42010-03-07 15:23:59 +00004986- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00004988
Georg Brandl3ee81df2008-05-17 18:14:43 +00004989- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4990 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004991 to compact the internal free lists of pre-allocted ints and floats.
4992
Georg Brandl3ee81df2008-05-17 18:14:43 +00004993- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4994 calls. Python expected the return type int but the fork familie
4995 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004996

Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- Patch #1473257: generator objects gain a gi_code attribute. This is
5010 the same object as the func_code attribute of the function that
5011 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005012
Georg Brandl3ee81df2008-05-17 18:14:43 +00005013- Issue #1920: "while 0" statements were completely removed by the
5014 compiler, even in the presence of an "else" clause, which is
5015 supposed to be run when the condition is false. Now the compiler
5016 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005017
Guido van Rossumeead05f2008-01-24 18:21:02 +00005018- A few crashers fixed: weakref_in_del.py (issue #1377858);

5025
Georg Brandl3ee81df2008-05-17 18:14:43 +00005026- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005027 several extension methods and modules do not work without unicode
5028 support.
5029

5034
Georg Brandl6caad7d2008-01-26 14:19:22 +00005035- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005036 added.
5037
Christian Heimesc94e2b52008-01-14 04:13:37 +00005038- sys.float_info / PyFloat_GetInfo: The floating point information
5039 object was converted from a dict to a specialized structseq object.
5040
Georg Brandl3ee81df2008-05-17 18:14:43 +00005041- Patch #1816: Added sys.flags structseq. It exposes the status of
5042 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005043
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005048- Patch #1700288: added a type attribute cache that caches method
5049 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandlaed6c662008-01-07 17:25:53 +00005054- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5055
Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5057 envvar and sys.dont_write_bytecode attribute. All these can be set
5058 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005059
Georg Brandl3ee81df2008-05-17 18:14:43 +00005060- Improve some exception messages when Windows fails to load an
5061 extension module. Now we get for example '%1 is not a valid Win32
5062 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005069- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005070 and INF. float("nan"), float("inf") and float("-inf") now work on
5071 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Compiler now generates simpler and faster code for dictionary
5074 literals. The oparg for BUILD_MAP now indicates an estimated
5075 dictionary size. There is a new opcode, STORE_MAP, for adding
5076 entries to the dictionary.

5088
Nick Coghlanef01d822007-12-03 12:55:17 +00005089- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005105- Patch #1739468: Directories and zipfiles containing a __main__.py
5106 file can now be directly executed by passing their name to the
5107 interpreter. The directory/zipfile is automatically inserted as the
5108 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005109
Georg Brandl3ee81df2008-05-17 18:14:43 +00005110- Issue #1265: Fix a problem with sys.settrace, if the tracing
5111 function uses a generator expression when at the same time the
5112 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005113
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005114- sets and frozensets now have an isdisjoint() method.
5115

5119
Georg Brandl21e99f42010-03-07 15:23:59 +00005120- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005121 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5122 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Issue #1686386: Tuple's tp_repr did not take into account the
5125 possibility of having a self-referential tuple, which is possible
5126 from C code. Nor did object's tp_str consider that a type's tp_str
5127 could do something that could lead to an inifinite recursion.
5128 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5129 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005130
Georg Brandl3ee81df2008-05-17 18:14:43 +00005131- Issue #1164: It was possible to trigger deadlock when using the
5132 'print' statement to write to a file since the GIL was not released
5133 as needed. Now PyObject_Print() does the right thing along with
5134 various tp_print implementations of the built-in types and those in
5135 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- Issue #1147: Exceptions were directly allowing string exceptions in
5138 their throw() method even though string exceptions no longer
5139 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Issue #1096: Prevent a segfault from getting the repr of a very
5142 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005143
Brett Cannon1e534b52007-09-07 04:18:30 +00005144- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145 PyObject_Call() never calling back out to Python code to trigger
5146 recursion depth updates/checks. Required the creation of a static
5147 RuntimeError instance in case normalizing an exception put the
5148 recursion check value past its limit. Fixes crashers
5149 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005150
Georg Brandl3ee81df2008-05-17 18:14:43 +00005151- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005164- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165 __*__ attributes. (Some already existed, e.g., __doc__ and
5166 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005167
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005168- Add -3 option to the interpreter to warn about features that are
5169 deprecated and will be changed/removed in Python 3.0.
5170
Georg Brandl2134e752007-05-21 20:34:16 +00005171- Patch #1686487: you can now pass any mapping after '**' in function
5172 calls.
5173
Collin Winter62903052007-05-18 23:11:24 +00005174- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175 "except E as target:". This is to provide forwards compatibility
5176 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005177
Brett Cannon229cee22007-05-05 01:34:02 +00005178- Deprecate BaseException.message as per PEP 352.
5179
Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005181 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005182
Vinay Sajip8549ce32007-05-06 17:53:37 +00005183- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005184 setting a plain string, ie don't expand to single letter identifiers.
5185
Raymond Hettinger13936692007-04-11 18:40:58 +00005186- Request #1191699: Slices can now be pickled.
5187
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005188- Request #1193128: str.translate() now allows a None argument for
5189 translations that only remove characters without re-mapping the
5190 remaining characters.
5191
Georg Brandl5cb76c12007-03-21 09:00:39 +00005192- Patch #1682205: a TypeError while unpacking an iterable is no longer
5193 masked by a generic one with the message "unpack non-sequence".
5194
Neal Norwitzaa754b72007-03-21 06:39:48 +00005195- Remove unused file Python/fmod.c.
5196
Guido van Rossum143b5642007-03-23 04:58:42 +00005197- Bug #1683368: The object.__init__() and object.__new__() methods are
5198 now stricter in rejecting excess arguments. The only time when
5199 either allows excess arguments is when it is not overridden and the
5200 other one is. For backwards compatibility, when both are
5201 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005202 warning later). Also, type.__init__() insists on the same signature
5203 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005204
Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5206 object to complex using its __complex__() method before falling back
5207 to the __float__() method. Therefore, the functions in the cmath
5208 module now can operate on objects that define a __complex__()
5209 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005210
Georg Brandl3ee81df2008-05-17 18:14:43 +00005211- Patch #1623563: allow __class__ assignment for classes with
5212 __slots__. The old and the new class are still required to have the
5213 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005214
Georg Brandl3ee81df2008-05-17 18:14:43 +00005215- Patch #1642547: Fix an error/crash when encountering syntax errors

5219 ``object.__reduce_ex__()`` is called with an object that is faking
5220 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005221
Georg Brandl3ee81df2008-05-17 18:14:43 +00005222- Patch #1680015: Don't modify __slots__ tuple if it contains an

5226
Georg Brandl7b9c5552007-03-12 14:30:05 +00005227- Bug #1678647: write a newline after printing an exception in any
5228 case, even when converting the value to a string failed.
5229
Georg Brandl871f1bc2007-03-12 13:17:36 +00005230- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005231 its argument, if it exists. If not, it will work like before. This
5232 allows customizing the output of dir() in the presence of a
5233 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005234
Collin Winter276887b2007-03-12 16:11:39 +00005235- Patch #922167: Python no longer segfaults when faced with infinitely
5236 self-recursive reload() calls (as reported by bug #742342).
5237
Georg Brandl3ee81df2008-05-17 18:14:43 +00005238- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Patch #1491866: change the complex() constructor to allow
5242 parthensized forms. This means complex(repr(x)) now works instead of
5243 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005244
Georg Brandlaa2321b2007-03-07 00:40:28 +00005245- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005246 makes the filenames the warning module prints much more sensible
5247 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005248
Georg Brandl49aafc92007-03-07 00:34:46 +00005249- Variant of patch #697613: don't exit the interpreter on a SystemExit
5250 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005251 variable is given, but break into the interactive interpreter just
5252 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005260- Patch #1674228: when assigning a slice (old-style), check for the
5261 sq_ass_slice instead of the sq_slice slot.
5262
Georg Brandl3ee81df2008-05-17 18:14:43 +00005263- When printing an unraisable error, don't print exceptions. before
5264 the name. This duplicates the behavior whening normally printing
5265 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005798 AttributeError instead of an IOError when the server's response
5799 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005800

Georg Brandl3ee81df2008-05-17 18:14:43 +00005805- Patch #1429539: pdb now correctly initializes the __main__ module
5806 for the debugged script, which means that imports from __main__ work

5815
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Patch #1530482: add pydoc.render_doc() which returns the

5831
Georg Brandl92a6bae2007-03-13 17:43:32 +00005832- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005833 are set for invalid interpolation sequences that would lead to
5834 errors on reading back those values.

5877 returned string up to the first NUL character.

5888
Georg Brandl3ee81df2008-05-17 18:14:43 +00005889- unittest now verifies more of its assumptions. In particular,
5890 TestCase and TestSuite subclasses (not instances) are no longer
5891 accepted in TestSuite.addTest(). This should cause no
5892 incompatibility since it never made sense with ordinary subclasses
5893 -- the failure just occurred later, with a more cumbersome
5894 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006181 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- Marshal.dumps() now expects exact type matches for int, long, float,
6265 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6266 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006282- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006283 time so that opening a database previously created with the DB_DUP
6284 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6285 opens. Specifically: dictionary assignment to a DB object will
6286 replace all values for a given key when the database allows
6287 duplicate values. DB users should use DB.put(k, v) when they want
6288 to store duplicates; not DB[k] = v.

6295 characters with ASCII value less than 32. Also, it correctly quotes
6296 dots only if they occur on a single line, as opposed to the previous
6297 behavior of quoting dots if they are the second character of any
6298 line.

6644 of w# format code incorrectly truncated the length to an int, even
6645 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6646 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006676- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6677 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
