139 fix various SSLSocket methods to raise socket.error rather than an

141 by Andrew Bennetts.

Raymond Hettinger20397532010-09-12 02:11:45 +0000151- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
152 This prevents user-created self-referencing ordered dictionaries from
153 becoming permanently uncollectable GC garbage. The downside is that
154 removing __del__ means that the internal doubly-linked list has to wait for
155 GC collection rather than freeing memory immediately when the refcnt drops
156 to zero.
157
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000158- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000160 value.
161
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000162- Issue #9792: In case of connection failure, socket.create_connection()
163 would swallow the exception and raise a new one, making it impossible
164 to fetch the original errno, or to filter timeout errors. Now the
165 original error is re-raised.
166
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000167- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
168 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
169 be updated back after the system call. Original patch by Brian Brazil.
170
Antoine Pitroudca9de92010-09-04 17:52:26 +0000171- Issue #1100562: Fix deep-copying of objects derived from the list and
172 dict types. Patch by Michele Orrù and Björn Lindqvist.
173
Fred Drakea1e627d2010-09-03 03:55:50 +0000174- Issue #7005: Fixed output of None values for RawConfigParser.write and
175 ConfigParser.write.
176
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000177- Issue #808164: Fixed socket.close to avoid references to globals, to
178 avoid issues when socket.close is called from a __del__ method.
179
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000180- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

182
R. David Murray7c4bf552010-08-25 01:45:57 +0000183- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
184 character years even if the message contains RFC822 two character years.
185
Daniel Stutzbach91287322010-08-24 21:09:30 +0000186- Issue #8750: Fixed MutableSet's methods to correctly handle
187 reflexive operations, namely x -= x and x ^= x.
188
Victor Stinnercaafd772010-09-08 10:51:01 +0000189- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000190 error handling when accepting a new connection.

199
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000200- Issue #9617: Signals received during a low-level write operation aren't
201 ignored by the buffered IO layer anymore.
202
Benjamin Peterson52c36052010-08-21 03:03:22 +0000203- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
204 are not held onto after they are deleted elsewhere.
205
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000206- Issue #9626: the view methods for collections.OrderedDict() were returning
207 the unordered versions inherited from dict. Those methods are now
208 overridden to provide ordered views.
209
Éric Araujo0389ae62010-08-14 03:07:46 +0000210- Issue #8688: MANIFEST files created by distutils now include a magic

227 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
228
Antoine Pitrou99009162010-08-09 22:51:24 +0000229- Issue #3757: thread-local objects now support cyclic garbage collection.

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

625 objects. (1) The comparison could incorrectly return True in some cases
626 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
627 (2) The comparison raised an OverflowError for large integers, leading
628 to unpredictable exceptions when combining integers and complex objects
629 in sets or dicts.

Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000998- Issue #8329: Don't return the same lists from select.select when no fds are
999 changed.

1003 permitted to be up to sys.maxsize.
1004
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001005- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00001011- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1012 with a non-empty format string. This is an effort to future-proof user
1013 code. If a derived class does not currently implement __format__ but later
1014 adds its own __format__, it would most likely break user code that had
1015 supplied a format string. This will be changed to a DeprecationWaring in
1016 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001049- Issue #8257: The Decimal construct now accepts a float instance directly,
1050 converting that float to a Decimal of equal value:

1054
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001055- collections.Counter() now supports a subtract() method.
1056
Georg Brandlfee0f442010-05-22 21:26:21 +00001057- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001066- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1067 InvalidOperation instead of returning False. (Comparisons involving a quiet
1068 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1069 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001071- Issue #2531: Comparison operations between floats and Decimal instances now
1072 return a result based on the numeric values of the operands; previously they
1073 returned an arbitrary result based on the relative ordering of id(float) and
1074 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001076- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001077 argument `-` which tells it to read files to compile from stdin. Each line is
1078 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001088- Comparisons using one of <, <=, >, >= between a complex instance and a
1089 Fractions instance now raise TypeError instead of returning True/False. This
1090 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1091 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001444- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1445 and add the additional members returned in an OSVERSIONINFOEX structure. The
1446 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001449- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1450 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1451 returning NULL. The macro now returns a statically allocated empty string
1452 instead.

1462 strings,
1463 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1464 numeric strings corresponding to subnormal values,
1465 (3) a memory leak for some values large enough to cause overflow, and
1466 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001497- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001498 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001499 Also, raise ValueError rather than TypeError when an unknown TIPC address
1500 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001504- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001505 file position when calling `truncate()`. It would previously change the file
1506 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001507 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1508
Georg Brandlba83f822010-03-14 09:50:54 +00001509- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1510 class used to represent files stored inside an archive. The new
1511 implementation is significantly faster and can be wrapped in a
1512 ``io.BufferedReader`` object for more speedups. It also solves an issue
1513 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001524- Issue #7748: Since unicode values are supported for some metadata options in
1525 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1526 encoded string for them. This ensures that the upload and register commands
1527 send the correct values to PyPI without any error.

1602-----------------
1603
Georg Brandlba83f822010-03-14 09:50:54 +00001604- The ``__complex__()`` method is now looked up on the class of instances to
1605 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001606
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001607- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1608 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1609
Mark Dickinson1b34d252010-01-01 17:27:30 +00001610- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001611 DeprecationWarning when passed a float argument where an integer was expected.
1612 These functions and methods now raise TypeError instead. The majority of the
1613 effects of this change are in the extension modules, but some core functions
1614 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1615 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001616
Benjamin Peterson0f02d392009-12-30 19:34:10 +00001617- Issue #7604: Deleting an unset slotted attribute did not raise an
1618 AttributeError.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001625- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1626 used to drop the time part of the result.
1627
Georg Brandlba83f822010-03-14 09:50:54 +00001628- Issue #1811: Improve accuracy and cross-platform consistency for true division
1629 of integers: the result of a/b is now correctly rounded for ints a and b (at
1630 least on IEEE 754 platforms), and in particular does not depend on the
1631 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001632
Georg Brandlba83f822010-03-14 09:50:54 +00001633- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1634 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1635 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001636

Ronald Oussoren92919a62009-12-24 13:30:58 +00001638 executables on OSX.
1639
Georg Brandlba83f822010-03-14 09:50:54 +00001640 These executables now work properly with the arch(1) command: ``arch -ppc
1641 python`` will start a universal binary version of python in PPC mode (unlike
1642 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001643
Georg Brandlba83f822010-03-14 09:50:54 +00001644- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1645 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +00001656- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
1657 allowing for a maximum number of tasks within the pool to be completed by the
1658 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00001664- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001665 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1666 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00001685- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00001686 Initial patch by Brian Curtin.
1687
Georg Brandlba83f822010-03-14 09:50:54 +00001688- Distutils now correctly identifies the build architecture as "x86_64" when
1689 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00001690

Benjamin Petersonddd392c2009-12-13 19:19:07 +00001701- Issue #7349: Make methods of file objects in the io module accept None as an
1702 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1703 the same as passing no argument.
1704
Georg Brandlba83f822010-03-14 09:50:54 +00001705- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00001727- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
1728 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
1729 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
1730 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00001798- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1799 decimal string that's guaranteed to round back to x under correct rounding
1800 (with round-half-to-even rounding mode). Previously it gave a string based on
1801 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1802 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1803 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001804
Georg Brandlba83f822010-03-14 09:50:54 +00001805- Issue #7117: On almost all platforms: float-to-string and string-to-float
1806 conversions within Python are now correctly rounded. Places these conversions
1807 occur include: str for floats and complex numbers; the float and complex
1808 constructors; old-style and new-style numeric formatting; serialization and
1809 deserialization of floats and complex numbers using marshal, pickle and json;
1810 parsing of float and imaginary literals in Python code; Decimal-to-float
1811 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001812
Georg Brandlba83f822010-03-14 09:50:54 +00001813 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1814 providing correctly-rounded strtod and dtoa C functions. This code is
1815 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1816 the C compiler. There may be a small number of platforms on which correct
1817 operation of this code cannot be guaranteed, so the code is not used: notably,
1818 this applies to platforms where the C double format is not IEEE 754 binary64,
1819 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1820 and Python's configure script is unable to determine how to change the FPU
1821 precision. On these platforms conversions use the platform strtod and dtoa,
1822 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001823
Georg Brandlba83f822010-03-14 09:50:54 +00001824- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1825 uses the correctly-rounded string <-> float conversions described above (when
1826 available), and so produces correctly rounded results that will display nicely
1827 under the float repr. There are two related small changes: (1) round now
1828 accepts any class with an ``__index__()`` method for its second argument (but
1829 no longer accepts floats for the second argument), and (2) an excessively
1830 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1831 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002049 untrackable objects are not tracked by the garbage collector. This can reduce
2050 the size of collections and therefore the garbage collection overhead on
2051 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002057- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2058 internal representation of integers, for performance reasons. Base 2**30 is
2059 enabled by default on 64-bit machines. Add --enable-big-digits option to
2060 configure, which overrides the default. Add sys.long_info structseq to
2061 provide information about the internal format.

2092
Georg Brandl29c6a282009-04-05 20:23:13 +00002093- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002094 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00002124- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2125 existing .py counterpart, override the co_filename attributes of all code
2126 objects if the original filename is obsolete (which can happen if the file has

2181
Georg Brandlba83f822010-03-14 09:50:54 +00002182- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2183 file objects with closefd=False. The file descriptor is still kept open but
2184 the file object behaves like a closed file. The ``FileIO`` object also got a
2185 new readonly attribute ``closefd``.

2204
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002205- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002206 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002208- On windows, ``os.chdir()`` given unicode was not working if
2209 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2210 this code path is really executed because I cannot move to such directory on
2211 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002213- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2214 element is temporarily replaced with an equivalent frozenset. But the
2215 eventual KeyError would always report the empty ``frozenset()`` as the missing
2216 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002236- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2237 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2238 step. This avoids problems with counting UTF-8 bytes that ignores the effect

2240
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002241- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002244- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3413 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3414 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3415 neither __int__ nor __long__, TypeError used to be raised (with a
3416 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3417 struct.error in other cases.

3420 argument with an __int__ method can be packed, but use of this feature
3421 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003614- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3616 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3617 ``printf`` function, whereas PyString_FromFormat has an independent
3618 implementation and uses "%zd" on all platforms for size_t values.
3619 This makes a difference on win64, where ``printf`` needs "%Id" to display
3620 64bit values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003715 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3716 for catch_warnings() also led to an improvement in the raising of a
3717 DeprecationWarning related to warnings.warn_explicit().
3718

3741
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003742- Issue #2975: When compiling several extension modules with Visual Studio 2008
3743 from the same python interpreter, some environment variables would grow
3744 without limit.
3745
Benjamin Peterson37346b22008-08-23 20:27:43 +00003746- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003783What's New in Python 2.6 beta 3?
3784================================
3785
Barry Warsaw07a4a382008-08-21 01:15:08 +00003786*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003787
3788Core and Builtins
3789-----------------
3790
Guido van Rossumf8402962008-08-20 15:01:50 +00003791- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3792 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3793 extensions do not automatically benefit from the class attribute
3794 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3795 to their tp_flags field if they care. This is a backwards
3796 compatibility feature; in 3.0, all types will use the cache by
3797 default.
3798
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003799- Keyword arguments can now follow starred arguments. (``f(a, *args,
3800 keyword=23)`` is now valid syntax.)
3801
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003802- ctypes function pointers that are COM methods have a boolean True
3803 value again.
3804
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003805- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3806 by denying s# to parse objects that have a releasebuffer procedure,
3807 and introducing s*.
3808
Georg Brandl1e13ea92008-08-11 09:07:59 +00003809- Issue #3537: Fix an assertion failure when an empty but presized dict
3810 object was stored in the freelist.
3811
Mark Dickinsonb6467572008-08-04 21:30:09 +00003812- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3813 ValueError consistently across platforms.
3814
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003815- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3816 (64bit Unix, for example), unichr() would truncate its argument and return
3817 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3818
Neal Norwitze7d8be82008-07-31 17:17:14 +00003819- Apply security patches from Apple.
3820
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003821- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3822 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3823
Antoine Pitrou92f82162008-07-25 22:22:08 +00003824- Issue #1819: function calls with several named parameters are now on
3825 average 35% faster (as measured by pybench).
3826
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003827- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3828 the python debugger steps into a class statement: the free variables (local
3829 variables defined in an outer scope) would be deleted from the outer scope.
3830
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003831- Issue #2620: Overflow checking when allocating or reallocating memory
3832 was not always being done properly in some python types and extension
3833 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3834 all been updated to perform better checks and places in the code that
3835 would previously leak memory on the error path when such an allocation
3836 failed have been fixed.
3837

3839-------
3840

3842
Benjamin Petersone977ad42008-08-20 01:42:01 +00003843- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3844 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3845
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003846- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3847 version reported by these tools does not necessarily follow the python
3848 version numbering scheme, so the module is less strict when parsing it.
3849
Nick Coghlanf70385a2008-08-18 12:42:46 +00003850- Issue #2235: Added Py3k warnings for types which will become unhashable
3851 under the stricter __hash__ inheritance rules in 3.0. Several types
3852 which did not meet the rules for hash invariants and were already
3853 unhashable in 3.0 have now been explicitly flagged as unhashable in
3854 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3855 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3856
Brett Cannon88f801d2008-08-18 00:46:22 +00003857- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3865
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003866- Issue #3575: Incremental decoder's decode function now takes bytearray
3867 by using 's*' instead of 't#'.
3868
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003869- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003870 fails unicode conversion on 2nd parameter. (windows only)
3871
Georg Brandl222e2082010-08-01 22:27:39 +00003872- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003873 in a redirect.
3874

Brett Cannon721b1452008-08-16 22:00:27 +00003876 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003877
Facundo Batistaeb90b782008-08-16 14:44:07 +00003878- Issue #2776: fixed small issue when handling an URL with double slash
3879 after a 302 response in the case of not going through a proxy.
3880
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003881- Issue #2676: in the email package, content-type parsing was hanging on
3882 pathological input because of quadratic or exponential behaviour of a
3883 regular expression.
3884
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003885- Issue #3476: binary buffered reading through the new "io" library is now
3886 thread-safe.
3887
Brett Cannonbf3157b2008-08-14 05:00:03 +00003888- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3889 since mimetools itself is deprecated. Because modules are cached, all
3890 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3891
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003892- Issue #3134: shutil referenced undefined WindowsError symbol.
3893
Robert Schuppenies14646332008-08-10 11:01:53 +00003894- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3895 menu entries were not deleted.
3896
Brett Cannon83e81842008-08-09 23:30:55 +00003897- Copied the implementation of reduce() to _functools.reduce() to have a
3898 version that did not raise a DeprecationWarning under -3.
3899
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003900- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3901 a MemoryError rather than silently stop the iteration.
3902
Guido van Rossum59ce9012008-08-09 14:55:34 +00003903- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3904 to _sre.compile() will now be rejected. This should not affect anybody
3905 since the re.compile() function never generates invalid re-bytecode.
3906
Skip Montanaroa032bf42008-08-08 22:52:51 +00003907- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3908 upon first access it can be automatically initialized from the csv file if
3909 it wasn't initialized during instantiation.
3910
Brett Cannon3aa2a492008-08-06 22:28:09 +00003911- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3912 the reload() built-in has been removed.
3913
Brett Cannon7e30b672008-08-04 21:52:25 +00003914- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003915 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003926 asking for a specific length. This problem only affected files opened
3927 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003928

3973 regarding lack of coverage of new-style classes have also been
3974 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003977What's New in Python 2.6 beta 2?
3978================================
3979
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003980*Release date: 17-Jul-2008*
3981
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003982Core and Builtins
3983-----------------
3984
Georg Brandl3e483f62008-07-16 22:57:41 +00003985- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3986 its methods now allow for items objects that can be converted to
3987 an integer using operator.index().
3988
Mark Dickinson64b7e502008-07-16 09:40:03 +00003989- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3990 produced a ValueError instead of giving the correct float.
3991
Eric Smitha5fa5a22008-07-16 00:11:49 +00003992- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3993 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3994
Mark Dickinson7103aa42008-07-15 19:08:33 +00003995- Issue #3008: the float type has a new instance method 'float.hex'
3996 and a new class method 'float.fromhex' to convert floating-point
3997 numbers to and from hexadecimal strings, respectively.
3998
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003999- Issue #2235: __hash__ is once again inherited by default. To allow
4000 collections.Hashable to remain meaningful in the presence of the
4001 default hash implementation (object.__hash__), it is now possible
4002 to explicit block inheritance of hash by setting __hash__=None at
4003 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4004 level.
4005
Nick Coghlanb028f502008-07-13 14:52:36 +00004006- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4007 the parent module cannot be found while performing an absolute import.
4008 This means that an incorrectly defined __package__ attribute will
4009 now only prevent relative imports in that module rather than causing
4010 all imports from that module to fail.
4011
Nick Coghlan14ff9942008-07-08 14:21:42 +00004012- Issue #2517: Allow unicode messages in Exceptions again by correctly
4013 bypassing the instance dictionary when looking up __unicode__ on
4014 new-style classes.
4015
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004016- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4017 set to a custom object whose write() method happens to install
4018 another file in sys.stdout.
4019
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004020- Issue #3088: Corrected a race condition in classes derived from
4021 threading.local: the first member set by a thread could be saved in
4022 another thread's dictionary.
4023
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004024- Issue #3004: Minor change to slice.indices(): the start and stop
4025 arguments are now treated identically, making the behaviour easier
4026 to describe and understand. For example, slice(None, -10,
4027 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4028 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4029 10, -1).
4030
Georg Brandl278fc502008-07-19 12:46:12 +00004031- Issue #3219: Calling a function with repeated keyword arguments,
4032 f(a=2, a=23), would not cause a syntax error. This was a regression
4033 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004034
Georg Brandl278fc502008-07-19 12:46:12 +00004035- Issue #2862: Make int and float freelist management consistent with
4036 other freelists. Changes their CompactFreeList apis into
4037 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004038
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004039Library
4040-------
4041
Thomas Heller57adf222008-08-14 19:10:48 +00004042- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4043 api functions without holding the GIL, which could lead to a fatal
4044 error when they failed.
4045
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004046- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4047

4053
Jesse Noller13e9d582008-07-16 14:32:36 +00004054- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4055 ForkingPickler.register() to resolve conflict with ctypes.
4056
Vinay Sajip51e65192008-07-18 09:01:10 +00004057- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004058
Thomas Heller880f5292008-07-15 19:39:38 +00004059- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4060 a valid dlerror() message.
4061
Thomas Heller2bad6572008-07-15 17:19:50 +00004062- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4063 incomplete structure was created.
4064
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004065- Issue #3339: dummy_thread.acquire() should not return None.
4066
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004067- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4068
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004069- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004070
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004071- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4072 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004073 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004074 content-length. The problem had been corrected in the 2.4 branch, but never
4075 merged into trunk.
4076
Georg Brandle78fbcc2008-07-05 10:13:36 +00004077- Issue #2663: add filtering capability to shutil.copytree().
4078

4080
4081- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4082
4083- Issue #1746: Correct handling of zipfile archive comments (previously
4084 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004085 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004086
Vinay Sajip51e65192008-07-18 09:01:10 +00004087- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004088 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004089
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004090- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4091 handling is now the same as that of other special attributes like __name__).
4092
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004093- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4094 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- Issue #1631171: Re-implement the 'warnings' module in C (the
4546 original Python code has been kept as backup). This will allow for
4547 using the 'warning's machinery in such places as the parser where
4548 use of pure Python code is not possible. Both the ``showarning()``
4549 and ``formatwarning()`` gain an optional 'line' argument which is
4550 not called by default for backwards-compatibility reasons. Setting
4551 ``warnings.showwarning()`` to an implementation that lacks support
4552 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Issue #2550: The approach used by client/server code for obtaining
4616 ports to listen on in network-oriented tests has been refined in an
4617 effort to facilitate running multiple instances of the entire
4618 regression test suite in parallel without issue.
4619 test_support.bind_port() has been fixed such that it will always
4620 return a unique port -- which wasn't always the case with the
4621 previous implementation, especially if socket options had been set
4622 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4623 new implementation of bind_port() will actually raise an exception
4624 if it is passed an AF_INET/SOCK_STREAM socket with either the
4625 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4626 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4627 the socket it's been passed. This currently only applies to
4628 Windows. This option prevents any other sockets from binding to the
4629 host/port we've bound to, thus removing the possibility of the
4630 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4631 when a second SOCK_STREAM socket binds and accepts to a host/port
4632 that's already been bound by another socket. The optional preferred
4633 port parameter to bind_port() has been removed. Under no
4634 circumstances should tests be hard coding ports!
4635
4636 test_support.find_unused_port() has also been introduced, which will
4637 pass a temporary socket object to bind_port() in order to obtain an
4638 unused port. The temporary socket object is then closed and
4639 deleted, and the port is returned. This method should only be used
4640 for obtaining an unused port in order to pass to an external program
4641 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4642 a parameter to a server-oriented class that doesn't give you direct
4643 access to the underlying socket used.
4644
4645 Finally, test_support.HOST has been introduced, which should be used
4646 for the host argument of any relevant socket calls (i.e. bind and
4647 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004648
4649 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004650 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004651 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4652 test_asynchat and test_socket_ssl.
4653
Georg Brandl3ee81df2008-05-17 18:14:43 +00004654 It is now possible for multiple instances of the regression test
4655 suite to run in parallel without issue.

4811 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00004812 platform.machine() and platform.processor() will report this
4813 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00004934- Added the future_builtins module, which contains hex() and oct().
4935 These are the PEP 3127 version of these functions, designed to be
4936 compatible with the hex() and oct() builtins from Python 3.0. They
4937 differ slightly in their output formats from the existing, unchanged
4938 Python 2.6 builtins. The expected usage of the future_builtins
4939 module is:
4940 from future_builtins import hex, oct
4941
Eric Smith7ef40bf2008-02-20 23:34:22 +00004942- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4943 exponents for exponents with absolute value < 100. Follows C99
4944 standard. This is a change on Windows, which would use 3 digits.
4945 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4946 so that any alterations it does to the resulting string will be
4947 available in stringlib/formatter.h (for float.__format__).
4948
Eric Smith5a3c1352008-02-19 13:21:56 +00004949- Implemented PEP 3101, Advanced String Formatting. This adds a new
4950 builtin format(); a format() method for str and unicode; a
4951 __format__() method to object, str, unicode, int, long, float, and
4952 datetime; the class string.Formatter; and the C API
4953 PyObject_Format().
4954
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Fixed several potential crashes, all caused by specially crafted
4956 __del__ methods exploiting objects in temporarily inconsistent
4957 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004958
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004959- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004960 prevent a possible crash: an Abstract Base Class would try to access
4961 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004966- Clear all free lists during a gc.collect() of the highest generation
4967 in order to allow pymalloc to free more arenas. Python may give back
4968 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Issue #2045: Fix an infinite recursion triggered when printing a
4971 subclass of collections.defaultdict, if its default_factory is set
4972 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004973
Christian Heimesf75dbef2008-02-08 00:11:31 +00004974- Fixed a minor memory leak in dictobject.c. The content of the free
4975 list was not freed on interpreter shutdown.
4976
Georg Brandl21e99f42010-03-07 15:23:59 +00004977- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004979
Georg Brandl3ee81df2008-05-17 18:14:43 +00004980- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4981 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004982 to compact the internal free lists of pre-allocted ints and floats.
4983
Georg Brandl3ee81df2008-05-17 18:14:43 +00004984- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4985 calls. Python expected the return type int but the fork familie
4986 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005000- Patch #1473257: generator objects gain a gi_code attribute. This is
5001 the same object as the func_code attribute of the function that
5002 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005003
Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- Issue #1920: "while 0" statements were completely removed by the
5005 compiler, even in the presence of an "else" clause, which is
5006 supposed to be run when the condition is false. Now the compiler
5007 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005008
Guido van Rossumeead05f2008-01-24 18:21:02 +00005009- A few crashers fixed: weakref_in_del.py (issue #1377858);
5010 loosing_dict_ref.py (issue #1303614, test67.py);
5011 borrowed_ref_[34].py (not in tracker).
5012

5016
Georg Brandl3ee81df2008-05-17 18:14:43 +00005017- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005018 several extension methods and modules do not work without unicode
5019 support.
5020
Georg Brandl26543b12008-01-21 18:36:51 +00005021- Issue #1882: when compiling code from a string, encoding cookies in the

5023
Georg Brandl14404b62008-01-19 19:27:05 +00005024- Issue #1679: "0x" was taken as a valid integer literal.
5025
Georg Brandl6caad7d2008-01-26 14:19:22 +00005026- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005027 added.
5028
Christian Heimesc94e2b52008-01-14 04:13:37 +00005029- sys.float_info / PyFloat_GetInfo: The floating point information
5030 object was converted from a dict to a specialized structseq object.
5031
Georg Brandl3ee81df2008-05-17 18:14:43 +00005032- Patch #1816: Added sys.flags structseq. It exposes the status of
5033 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005034
Georg Brandl3ee81df2008-05-17 18:14:43 +00005035- Objects/structseq.c: Implemented new structseq representation. The
5036 patch makes structseqs (e.g. the return value of os.stat) more
5037 readable.

5046
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5048 envvar and sys.dont_write_bytecode attribute. All these can be set
5049 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005050
Georg Brandl3ee81df2008-05-17 18:14:43 +00005051- Improve some exception messages when Windows fails to load an
5052 extension module. Now we get for example '%1 is not a valid Win32
5053 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005060- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005061 and INF. float("nan"), float("inf") and float("-inf") now work on
5062 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005064- Compiler now generates simpler and faster code for dictionary
5065 literals. The oparg for BUILD_MAP now indicates an estimated
5066 dictionary size. There is a new opcode, STORE_MAP, for adding
5067 entries to the dictionary.

5097 file can now be directly executed by passing their name to the
5098 interpreter. The directory/zipfile is automatically inserted as the
5099 first entry in sys.path.

5102 function uses a generator expression when at the same time the
5103 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005104

5110
Georg Brandl21e99f42010-03-07 15:23:59 +00005111- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5113 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005114
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115- Issue #1686386: Tuple's tp_repr did not take into account the
5116 possibility of having a self-referential tuple, which is possible
5117 from C code. Nor did object's tp_str consider that a type's tp_str
5118 could do something that could lead to an inifinite recursion.
5119 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5120 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005121
Georg Brandl3ee81df2008-05-17 18:14:43 +00005122- Issue #1164: It was possible to trigger deadlock when using the
5123 'print' statement to write to a file since the GIL was not released
5124 as needed. Now PyObject_Print() does the right thing along with
5125 various tp_print implementations of the built-in types and those in
5126 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00005134
Brett Cannon1e534b52007-09-07 04:18:30 +00005135- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005136 PyObject_Call() never calling back out to Python code to trigger
5137 recursion depth updates/checks. Required the creation of a static
5138 RuntimeError instance in case normalizing an exception put the
5139 recursion check value past its limit. Fixes crashers
5140 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005141

Neal Norwitz0ac60192007-05-27 04:08:54 +00005155- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005156 __*__ attributes. (Some already existed, e.g., __doc__ and
5157 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005158
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005159- Add -3 option to the interpreter to warn about features that are

5161
Georg Brandl2134e752007-05-21 20:34:16 +00005162- Patch #1686487: you can now pass any mapping after '**' in function
5163 calls.
5164
Collin Winter62903052007-05-18 23:11:24 +00005165- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166 "except E as target:". This is to provide forwards compatibility
5167 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005174- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005175 setting a plain string, ie don't expand to single letter identifiers.
5176
Raymond Hettinger13936692007-04-11 18:40:58 +00005177- Request #1191699: Slices can now be pickled.
5178
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005179- Request #1193128: str.translate() now allows a None argument for
5180 translations that only remove characters without re-mapping the
5181 remaining characters.
5182
Georg Brandl5cb76c12007-03-21 09:00:39 +00005183- Patch #1682205: a TypeError while unpacking an iterable is no longer

5187
Guido van Rossum143b5642007-03-23 04:58:42 +00005188- Bug #1683368: The object.__init__() and object.__new__() methods are
5189 now stricter in rejecting excess arguments. The only time when
5190 either allows excess arguments is when it is not overridden and the
5191 other one is. For backwards compatibility, when both are
5192 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005193 warning later). Also, type.__init__() insists on the same signature
5194 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5197 object to complex using its __complex__() method before falling back
5198 to the __float__() method. Therefore, the functions in the cmath
5199 module now can operate on objects that define a __complex__()
5200 method.

5217
Georg Brandl7b9c5552007-03-12 14:30:05 +00005218- Bug #1678647: write a newline after printing an exception in any
5219 case, even when converting the value to a string failed.
5220
Georg Brandl871f1bc2007-03-12 13:17:36 +00005221- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005222 its argument, if it exists. If not, it will work like before. This
5223 allows customizing the output of dir() in the presence of a
5224 __getattr__().

5233 parthensized forms. This means complex(repr(x)) now works instead of
5234 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005235
Georg Brandlaa2321b2007-03-07 00:40:28 +00005236- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237 makes the filenames the warning module prints much more sensible
5238 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005251- Patch #1674228: when assigning a slice (old-style), check for the
5252 sq_ass_slice instead of the sq_slice slot.
5253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005789 AttributeError instead of an IOError when the server's response
5790 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005791

Georg Brandl3ee81df2008-05-17 18:14:43 +00005807- Patch #1530482: add pydoc.render_doc() which returns the

5822
Georg Brandl92a6bae2007-03-13 17:43:32 +00005823- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005824 are set for invalid interpolation sequences that would lead to
5825 errors on reading back those values.

5879
Georg Brandl3ee81df2008-05-17 18:14:43 +00005880- unittest now verifies more of its assumptions. In particular,
5881 TestCase and TestSuite subclasses (not instances) are no longer
5882 accepted in TestSuite.addTest(). This should cause no
5883 incompatibility since it never made sense with ordinary subclasses
5884 -- the failure just occurred later, with a more cumbersome
5885 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006274 time so that opening a database previously created with the DB_DUP
6275 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6276 opens. Specifically: dictionary assignment to a DB object will
6277 replace all values for a given key when the database allows
6278 duplicate values. DB users should use DB.put(k, v) when they want
6279 to store duplicates; not DB[k] = v.

6286 characters with ASCII value less than 32. Also, it correctly quotes
6287 dots only if they occur on a single line, as opposed to the previous
6288 behavior of quoting dots if they are the second character of any
6289 line.

6635 of w# format code incorrectly truncated the length to an int, even
6636 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6637 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006667- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6668 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
