127 by Andrew Bennetts.

Raymond Hettinger20397532010-09-12 02:11:45 +0000137- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
138 This prevents user-created self-referencing ordered dictionaries from
139 becoming permanently uncollectable GC garbage. The downside is that
140 removing __del__ means that the internal doubly-linked list has to wait for
141 GC collection rather than freeing memory immediately when the refcnt drops
142 to zero.
143
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000144- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000145 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000146 value.
147
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000148- Issue #9792: In case of connection failure, socket.create_connection()
149 would swallow the exception and raise a new one, making it impossible
150 to fetch the original errno, or to filter timeout errors. Now the
151 original error is re-raised.
152
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000153- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
154 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
155 be updated back after the system call. Original patch by Brian Brazil.
156
Antoine Pitroudca9de92010-09-04 17:52:26 +0000157- Issue #1100562: Fix deep-copying of objects derived from the list and
158 dict types. Patch by Michele Orrù and Björn Lindqvist.

161 ConfigParser.write.
162
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000163- Issue #808164: Fixed socket.close to avoid references to globals, to
164 avoid issues when socket.close is called from a __del__ method.
165
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000166- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

170 character years even if the message contains RFC822 two character years.
171
Daniel Stutzbach91287322010-08-24 21:09:30 +0000172- Issue #8750: Fixed MutableSet's methods to correctly handle
173 reflexive operations, namely x -= x and x ^= x.
174
Victor Stinnercaafd772010-09-08 10:51:01 +0000175- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000176 error handling when accepting a new connection.
177
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000178- Issue #658749: asyncore's connect() method now correctly interprets winsock

184 module now correctly return a set. (Patch by Eli Bendersky.)
185
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000186- Issue #9617: Signals received during a low-level write operation aren't
187 ignored by the buffered IO layer anymore.
188
Benjamin Peterson52c36052010-08-21 03:03:22 +0000189- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
190 are not held onto after they are deleted elsewhere.
191
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000192- Issue #9626: the view methods for collections.OrderedDict() were returning
193 the unordered versions inherited from dict. Those methods are now
194 overridden to provide ordered views.
195
Éric Araujo0389ae62010-08-14 03:07:46 +0000196- Issue #8688: MANIFEST files created by distutils now include a magic
197 comment indicating they are generated. Manually maintained MANIFESTs
198 without this marker will not be overwritten or removed.
199
Antoine Pitroue1436d12010-08-12 15:25:51 +0000200- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

213 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
214

Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000982- Issue #7301: Add environment variable $PYTHONWARNINGS.
983
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000984- Issue #8329: Don't return the same lists from select.select when no fds are
985 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +0000997- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
998 with a non-empty format string. This is an effort to future-proof user
999 code. If a derived class does not currently implement __format__ but later
1000 adds its own __format__, it would most likely break user code that had
1001 supplied a format string. This will be changed to a DeprecationWaring in
1002 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001003

Georg Brandlfee0f442010-05-22 21:26:21 +00001035- Issue #8257: The Decimal construct now accepts a float instance directly,
1036 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001037

Raymond Hettinger34c35b22010-04-03 10:22:00 +00001041- collections.Counter() now supports a subtract() method.
1042
Georg Brandlfee0f442010-05-22 21:26:21 +00001043- The functools module now has a total_ordering() class decorator to simplify
1044 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001052- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1053 InvalidOperation instead of returning False. (Comparisons involving a quiet
1054 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1055 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001056
Georg Brandlfee0f442010-05-22 21:26:21 +00001057- Issue #2531: Comparison operations between floats and Decimal instances now
1058 return a result based on the numeric values of the operands; previously they
1059 returned an arbitrary result based on the relative ordering of id(float) and
1060 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001061
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001062- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001063 argument `-` which tells it to read files to compile from stdin. Each line is
1064 read on demand and the named file is compiled immediately. (Original patch by
1065 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001074- Comparisons using one of <, <=, >, >= between a complex instance and a
1075 Fractions instance now raise TypeError instead of returning True/False. This
1076 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1077 <=> complex, and complex <=> complex comparisons.

1186 the set of integer codes for which it was used differed between native packing
1187 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001435- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1436 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1437 returning NULL. The macro now returns a statically allocated empty string
1438 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001484 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001491 file position when calling `truncate()`. It would previously change the file
1492 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001493 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1494

1496 class used to represent files stored inside an archive. The new
1497 implementation is significantly faster and can be wrapped in a
1498 ``io.BufferedReader`` object for more speedups. It also solves an issue
1499 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001510- Issue #7748: Since unicode values are supported for some metadata options in
1511 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1512 encoded string for them. This ensures that the upload and register commands
1513 send the correct values to PyPI without any error.

1589
Georg Brandlba83f822010-03-14 09:50:54 +00001590- The ``__complex__()`` method is now looked up on the class of instances to
1591 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001593- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1594 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1595
Mark Dickinson1b34d252010-01-01 17:27:30 +00001596- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001597 DeprecationWarning when passed a float argument where an integer was expected.
1598 These functions and methods now raise TypeError instead. The majority of the
1599 effects of this change are in the extension modules, but some core functions
1600 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1601 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001611- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1612 used to drop the time part of the result.
1613
Georg Brandlba83f822010-03-14 09:50:54 +00001614- Issue #1811: Improve accuracy and cross-platform consistency for true division
1615 of integers: the result of a/b is now correctly rounded for ints a and b (at
1616 least on IEEE 754 platforms), and in particular does not depend on the
1617 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001618
Georg Brandlba83f822010-03-14 09:50:54 +00001619- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1620 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1621 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001622

Ronald Oussoren92919a62009-12-24 13:30:58 +00001624 executables on OSX.
1625
Georg Brandlba83f822010-03-14 09:50:54 +00001626 These executables now work properly with the arch(1) command: ``arch -ppc
1627 python`` will start a universal binary version of python in PPC mode (unlike
1628 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001629
Georg Brandlba83f822010-03-14 09:50:54 +00001630- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1631 underlying error when the coercion fails for the left hand operand.

1643 allowing for a maximum number of tasks within the pool to be completed by the
1644 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00001650- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001651 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1652 alternative to cPickle if you care about performance. Patch by Florent

1688 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1689 the same as passing no argument.
1690
Georg Brandlba83f822010-03-14 09:50:54 +00001691- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00001784- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1785 decimal string that's guaranteed to round back to x under correct rounding
1786 (with round-half-to-even rounding mode). Previously it gave a string based on
1787 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1788 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1789 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001790
Georg Brandlba83f822010-03-14 09:50:54 +00001791- Issue #7117: On almost all platforms: float-to-string and string-to-float
1792 conversions within Python are now correctly rounded. Places these conversions
1793 occur include: str for floats and complex numbers; the float and complex
1794 constructors; old-style and new-style numeric formatting; serialization and
1795 deserialization of floats and complex numbers using marshal, pickle and json;
1796 parsing of float and imaginary literals in Python code; Decimal-to-float
1797 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001798
Georg Brandlba83f822010-03-14 09:50:54 +00001799 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1800 providing correctly-rounded strtod and dtoa C functions. This code is
1801 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1802 the C compiler. There may be a small number of platforms on which correct
1803 operation of this code cannot be guaranteed, so the code is not used: notably,
1804 this applies to platforms where the C double format is not IEEE 754 binary64,
1805 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1806 and Python's configure script is unable to determine how to change the FPU
1807 precision. On these platforms conversions use the platform strtod and dtoa,
1808 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001810- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1811 uses the correctly-rounded string <-> float conversions described above (when
1812 available), and so produces correctly rounded results that will display nicely
1813 under the float repr. There are two related small changes: (1) round now
1814 accepts any class with an ``__index__()`` method for its second argument (but
1815 no longer accepts floats for the second argument), and (2) an excessively
1816 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1817 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001821- Fix several issues with ``compile()``. The input can now contain Windows and

2196 this code path is really executed because I cannot move to such directory on
2197 win2k)

2223 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003600- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3601 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3602 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3603 ``printf`` function, whereas PyString_FromFormat has an independent
3604 implementation and uses "%zd" on all platforms for size_t values.
3605 This makes a difference on win64, where ``printf`` needs "%Id" to display
3606 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003626 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00003701 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3702 for catch_warnings() also led to an improvement in the raising of a
3703 DeprecationWarning related to warnings.warn_explicit().
3704
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003705- The deprecation warnings for the old camelCase threading API were removed.

3727
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003728- Issue #2975: When compiling several extension modules with Visual Studio 2008
3729 from the same python interpreter, some environment variables would grow
3730 without limit.
3731
Benjamin Peterson37346b22008-08-23 20:27:43 +00003732- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3733 exploitation of poor argument checking.
3734
Gerhard Häringef2276b2008-09-12 13:54:06 +00003735- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003769What's New in Python 2.6 beta 3?
3770================================
3771
Barry Warsaw07a4a382008-08-21 01:15:08 +00003772*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003773
3774Core and Builtins
3775-----------------
3776
Guido van Rossumf8402962008-08-20 15:01:50 +00003777- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3778 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3779 extensions do not automatically benefit from the class attribute
3780 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3781 to their tp_flags field if they care. This is a backwards
3782 compatibility feature; in 3.0, all types will use the cache by
3783 default.
3784
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003785- Keyword arguments can now follow starred arguments. (``f(a, *args,
3786 keyword=23)`` is now valid syntax.)
3787
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003788- ctypes function pointers that are COM methods have a boolean True
3789 value again.
3790
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003791- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3792 by denying s# to parse objects that have a releasebuffer procedure,
3793 and introducing s*.
3794
Georg Brandl1e13ea92008-08-11 09:07:59 +00003795- Issue #3537: Fix an assertion failure when an empty but presized dict
3796 object was stored in the freelist.
3797
Mark Dickinsonb6467572008-08-04 21:30:09 +00003798- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3799 ValueError consistently across platforms.
3800
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003801- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3802 (64bit Unix, for example), unichr() would truncate its argument and return
3803 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3804
Neal Norwitze7d8be82008-07-31 17:17:14 +00003805- Apply security patches from Apple.
3806
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003807- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3808 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3809
Antoine Pitrou92f82162008-07-25 22:22:08 +00003810- Issue #1819: function calls with several named parameters are now on
3811 average 35% faster (as measured by pybench).
3812
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003813- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3814 the python debugger steps into a class statement: the free variables (local
3815 variables defined in an outer scope) would be deleted from the outer scope.
3816
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003817- Issue #2620: Overflow checking when allocating or reallocating memory
3818 was not always being done properly in some python types and extension
3819 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3820 all been updated to perform better checks and places in the code that
3821 would previously leak memory on the error path when such an allocation
3822 failed have been fixed.
3823
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003824Library
3825-------
3826
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003827- Issue #3612: Added some missing basic types in ctypes.wintypes.
3828
Benjamin Petersone977ad42008-08-20 01:42:01 +00003829- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3830 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3831
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003832- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3833 version reported by these tools does not necessarily follow the python
3834 version numbering scheme, so the module is less strict when parsing it.
3835
Nick Coghlanf70385a2008-08-18 12:42:46 +00003836- Issue #2235: Added Py3k warnings for types which will become unhashable
3837 under the stricter __hash__ inheritance rules in 3.0. Several types
3838 which did not meet the rules for hash invariants and were already
3839 unhashable in 3.0 have now been explicitly flagged as unhashable in
3840 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3841 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3842
Brett Cannon88f801d2008-08-18 00:46:22 +00003843- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3844 imported into the module but exposed as part of the module's API.
3845
Brett Cannon7b96f072008-08-18 00:41:11 +00003846- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3847
Brett Cannon46225e72008-08-18 00:36:52 +00003848- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003850- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3851
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003852- Issue #3575: Incremental decoder's decode function now takes bytearray
3853 by using 's*' instead of 't#'.
3854
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003855- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003856 fails unicode conversion on 2nd parameter. (windows only)
3857
Georg Brandl222e2082010-08-01 22:27:39 +00003858- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003859 in a redirect.
3860
Brett Cannonabe423e2008-08-16 21:47:07 +00003861- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003862 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003863
Facundo Batistaeb90b782008-08-16 14:44:07 +00003864- Issue #2776: fixed small issue when handling an URL with double slash
3865 after a 302 response in the case of not going through a proxy.
3866
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003867- Issue #2676: in the email package, content-type parsing was hanging on
3868 pathological input because of quadratic or exponential behaviour of a
3869 regular expression.
3870
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003871- Issue #3476: binary buffered reading through the new "io" library is now
3872 thread-safe.
3873
Brett Cannonbf3157b2008-08-14 05:00:03 +00003874- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3875 since mimetools itself is deprecated. Because modules are cached, all
3876 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3877
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003878- Issue #3134: shutil referenced undefined WindowsError symbol.
3879
Robert Schuppenies14646332008-08-10 11:01:53 +00003880- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3881 menu entries were not deleted.
3882
Brett Cannon83e81842008-08-09 23:30:55 +00003883- Copied the implementation of reduce() to _functools.reduce() to have a
3884 version that did not raise a DeprecationWarning under -3.
3885
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003886- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3887 a MemoryError rather than silently stop the iteration.
3888
Guido van Rossum59ce9012008-08-09 14:55:34 +00003889- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3890 to _sre.compile() will now be rejected. This should not affect anybody
3891 since the re.compile() function never generates invalid re-bytecode.
3892
Skip Montanaroa032bf42008-08-08 22:52:51 +00003893- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3894 upon first access it can be automatically initialized from the csv file if
3895 it wasn't initialized during instantiation.
3896
Brett Cannon3aa2a492008-08-06 22:28:09 +00003897- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3898 the reload() built-in has been removed.
3899
Brett Cannon7e30b672008-08-04 21:52:25 +00003900- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003901 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003912 asking for a specific length. This problem only affected files opened
3913 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003914

3939 file name rather than a ZipInfo instance, so files are extracted with
3940 mode 0600 rather than 000 under Unix.
3941

3959 regarding lack of coverage of new-style classes have also been
3960 removed, since the coverage is now fairly reasonable.

3976 produced a ValueError instead of giving the correct float.
3977
Eric Smitha5fa5a22008-07-16 00:11:49 +00003978- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Mark Dickinson7103aa42008-07-15 19:08:33 +00003981- Issue #3008: the float type has a new instance method 'float.hex'
3982 and a new class method 'float.fromhex' to convert floating-point
3983 numbers to and from hexadecimal strings, respectively.
3984
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003985- Issue #2235: __hash__ is once again inherited by default. To allow
3986 collections.Hashable to remain meaningful in the presence of the
3987 default hash implementation (object.__hash__), it is now possible
3988 to explicit block inheritance of hash by setting __hash__=None at
3989 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3990 level.
3991
Nick Coghlanb028f502008-07-13 14:52:36 +00003992- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3993 the parent module cannot be found while performing an absolute import.
3994 This means that an incorrectly defined __package__ attribute will
3995 now only prevent relative imports in that module rather than causing
3996 all imports from that module to fail.
3997
Nick Coghlan14ff9942008-07-08 14:21:42 +00003998- Issue #2517: Allow unicode messages in Exceptions again by correctly

4009
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004010- Issue #3004: Minor change to slice.indices(): the start and stop
4011 arguments are now treated identically, making the behaviour easier
4012 to describe and understand. For example, slice(None, -10,
4013 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4014 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4015 10, -1).

4058 both unnecessary (HTTP allows text content to be sent in several forms) and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004531- Issue #1631171: Re-implement the 'warnings' module in C (the
4532 original Python code has been kept as backup). This will allow for
4533 using the 'warning's machinery in such places as the parser where
4534 use of pure Python code is not possible. Both the ``showarning()``
4535 and ``formatwarning()`` gain an optional 'line' argument which is
4536 not called by default for backwards-compatibility reasons. Setting
4537 ``warnings.showwarning()`` to an implementation that lacks support
4538 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004601- Issue #2550: The approach used by client/server code for obtaining
4602 ports to listen on in network-oriented tests has been refined in an
4603 effort to facilitate running multiple instances of the entire
4604 regression test suite in parallel without issue.
4605 test_support.bind_port() has been fixed such that it will always
4606 return a unique port -- which wasn't always the case with the
4607 previous implementation, especially if socket options had been set
4608 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4609 new implementation of bind_port() will actually raise an exception
4610 if it is passed an AF_INET/SOCK_STREAM socket with either the
4611 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4612 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4613 the socket it's been passed. This currently only applies to
4614 Windows. This option prevents any other sockets from binding to the
4615 host/port we've bound to, thus removing the possibility of the
4616 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4617 when a second SOCK_STREAM socket binds and accepts to a host/port
4618 that's already been bound by another socket. The optional preferred
4619 port parameter to bind_port() has been removed. Under no
4620 circumstances should tests be hard coding ports!
4621
4622 test_support.find_unused_port() has also been introduced, which will
4623 pass a temporary socket object to bind_port() in order to obtain an
4624 unused port. The temporary socket object is then closed and
4625 deleted, and the port is returned. This method should only be used
4626 for obtaining an unused port in order to pass to an external program
4627 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4628 a parameter to a server-oriented class that doesn't give you direct
4629 access to the underlying socket used.
4630
4631 Finally, test_support.HOST has been introduced, which should be used
4632 for the host argument of any relevant socket calls (i.e. bind and
4633 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004634
4635 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004637 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4638 test_asynchat and test_socket_ssl.
4639
Georg Brandl3ee81df2008-05-17 18:14:43 +00004640 It is now possible for multiple instances of the regression test
4641 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004920- Added the future_builtins module, which contains hex() and oct().
4921 These are the PEP 3127 version of these functions, designed to be
4922 compatible with the hex() and oct() builtins from Python 3.0. They
4923 differ slightly in their output formats from the existing, unchanged
4924 Python 2.6 builtins. The expected usage of the future_builtins
4925 module is:
4926 from future_builtins import hex, oct
4927
Eric Smith7ef40bf2008-02-20 23:34:22 +00004928- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4929 exponents for exponents with absolute value < 100. Follows C99
4930 standard. This is a change on Windows, which would use 3 digits.
4931 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4932 so that any alterations it does to the resulting string will be
4933 available in stringlib/formatter.h (for float.__format__).
4934
Eric Smith5a3c1352008-02-19 13:21:56 +00004935- Implemented PEP 3101, Advanced String Formatting. This adds a new
4936 builtin format(); a format() method for str and unicode; a
4937 __format__() method to object, str, unicode, int, long, float, and
4938 datetime; the class string.Formatter; and the C API
4939 PyObject_Format().
4940
Georg Brandl3ee81df2008-05-17 18:14:43 +00004941- Fixed several potential crashes, all caused by specially crafted
4942 __del__ methods exploiting objects in temporarily inconsistent
4943 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004944
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004945- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004946 prevent a possible crash: an Abstract Base Class would try to access
4947 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004948
Georg Brandl3ee81df2008-05-17 18:14:43 +00004949- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00004952- Clear all free lists during a gc.collect() of the highest generation
4953 in order to allow pymalloc to free more arenas. Python may give back
4954 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004955
Georg Brandl3ee81df2008-05-17 18:14:43 +00004956- Issue #2045: Fix an infinite recursion triggered when printing a
4957 subclass of collections.defaultdict, if its default_factory is set
4958 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004959
Christian Heimesf75dbef2008-02-08 00:11:31 +00004960- Fixed a minor memory leak in dictobject.c. The content of the free
4961 list was not freed on interpreter shutdown.
4962
Georg Brandl21e99f42010-03-07 15:23:59 +00004963- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004964 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004965
Georg Brandl3ee81df2008-05-17 18:14:43 +00004966- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4967 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004968 to compact the internal free lists of pre-allocted ints and floats.
4969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4971 calls. Python expected the return type int but the fork familie
4972 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004973
Georg Brandl3ee81df2008-05-17 18:14:43 +00004974- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004986- Patch #1473257: generator objects gain a gi_code attribute. This is
4987 the same object as the func_code attribute of the function that
4988 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004989
Georg Brandl3ee81df2008-05-17 18:14:43 +00004990- Issue #1920: "while 0" statements were completely removed by the
4991 compiler, even in the presence of an "else" clause, which is
4992 supposed to be run when the condition is false. Now the compiler
4993 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004994
Guido van Rossumeead05f2008-01-24 18:21:02 +00004995- A few crashers fixed: weakref_in_del.py (issue #1377858);
4996 loosing_dict_ref.py (issue #1303614, test67.py);
4997 borrowed_ref_[34].py (not in tracker).
4998
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004999- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005000 suppressed while an extension is loaded by calling SetErrorMode in

5002
Georg Brandl3ee81df2008-05-17 18:14:43 +00005003- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005004 several extension methods and modules do not work without unicode
5005 support.
5006
Georg Brandl26543b12008-01-21 18:36:51 +00005007- Issue #1882: when compiling code from a string, encoding cookies in the
5008 second line of code were not always recognized correctly.
5009
Georg Brandl14404b62008-01-19 19:27:05 +00005010- Issue #1679: "0x" was taken as a valid integer literal.
5011
Georg Brandl6caad7d2008-01-26 14:19:22 +00005012- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005013 added.
5014
Christian Heimesc94e2b52008-01-14 04:13:37 +00005015- sys.float_info / PyFloat_GetInfo: The floating point information
5016 object was converted from a dict to a specialized structseq object.
5017
Georg Brandl3ee81df2008-05-17 18:14:43 +00005018- Patch #1816: Added sys.flags structseq. It exposes the status of
5019 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005020
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- Objects/structseq.c: Implemented new structseq representation. The
5022 patch makes structseqs (e.g. the return value of os.stat) more
5023 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005024
Georg Brandl3ee81df2008-05-17 18:14:43 +00005025- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005037- Improve some exception messages when Windows fails to load an
5038 extension module. Now we get for example '%1 is not a valid Win32
5039 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005046- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047 and INF. float("nan"), float("inf") and float("-inf") now work on
5048 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Compiler now generates simpler and faster code for dictionary
5051 literals. The oparg for BUILD_MAP now indicates an estimated
5052 dictionary size. There is a new opcode, STORE_MAP, for adding
5053 entries to the dictionary.

5083 file can now be directly executed by passing their name to the
5084 interpreter. The directory/zipfile is automatically inserted as the
5085 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005087- Issue #1265: Fix a problem with sys.settrace, if the tracing
5088 function uses a generator expression when at the same time the
5089 executed code is closing a paused generator.

5096
Georg Brandl21e99f42010-03-07 15:23:59 +00005097- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005098 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5099 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005100
Georg Brandl3ee81df2008-05-17 18:14:43 +00005101- Issue #1686386: Tuple's tp_repr did not take into account the
5102 possibility of having a self-referential tuple, which is possible
5103 from C code. Nor did object's tp_str consider that a type's tp_str
5104 could do something that could lead to an inifinite recursion.
5105 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5106 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005107
Georg Brandl3ee81df2008-05-17 18:14:43 +00005108- Issue #1164: It was possible to trigger deadlock when using the
5109 'print' statement to write to a file since the GIL was not released
5110 as needed. Now PyObject_Print() does the right thing along with
5111 various tp_print implementations of the built-in types and those in
5112 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005113
Georg Brandl3ee81df2008-05-17 18:14:43 +00005114- Issue #1147: Exceptions were directly allowing string exceptions in
5115 their throw() method even though string exceptions no longer
5116 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005118- Issue #1096: Prevent a segfault from getting the repr of a very
5119 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005120
Brett Cannon1e534b52007-09-07 04:18:30 +00005121- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005122 PyObject_Call() never calling back out to Python code to trigger
5123 recursion depth updates/checks. Required the creation of a static
5124 RuntimeError instance in case normalizing an exception put the
5125 recursion check value past its limit. Fixes crashers
5126 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005127

Neal Norwitz0ac60192007-05-27 04:08:54 +00005141- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142 __*__ attributes. (Some already existed, e.g., __doc__ and
5143 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005144
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005145- Add -3 option to the interpreter to warn about features that are
5146 deprecated and will be changed/removed in Python 3.0.
5147
Georg Brandl2134e752007-05-21 20:34:16 +00005148- Patch #1686487: you can now pass any mapping after '**' in function
5149 calls.
5150
Collin Winter62903052007-05-18 23:11:24 +00005151- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005152 "except E as target:". This is to provide forwards compatibility
5153 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00005155- Deprecate BaseException.message as per PEP 352.
5156
Georg Brandl3ee81df2008-05-17 18:14:43 +00005157- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005158 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005159
Vinay Sajip8549ce32007-05-06 17:53:37 +00005160- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005161 setting a plain string, ie don't expand to single letter identifiers.
5162
Raymond Hettinger13936692007-04-11 18:40:58 +00005163- Request #1191699: Slices can now be pickled.
5164
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005165- Request #1193128: str.translate() now allows a None argument for
5166 translations that only remove characters without re-mapping the
5167 remaining characters.
5168
Georg Brandl5cb76c12007-03-21 09:00:39 +00005169- Patch #1682205: a TypeError while unpacking an iterable is no longer

5173
Guido van Rossum143b5642007-03-23 04:58:42 +00005174- Bug #1683368: The object.__init__() and object.__new__() methods are
5175 now stricter in rejecting excess arguments. The only time when
5176 either allows excess arguments is when it is not overridden and the
5177 other one is. For backwards compatibility, when both are
5178 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005179 warning later). Also, type.__init__() insists on the same signature
5180 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005181
Georg Brandl3ee81df2008-05-17 18:14:43 +00005182- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5183 object to complex using its __complex__() method before falling back
5184 to the __float__() method. Therefore, the functions in the cmath
5185 module now can operate on objects that define a __complex__()
5186 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005187
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Patch #1623563: allow __class__ assignment for classes with
5189 __slots__. The old and the new class are still required to have the
5190 same slot names.

5196 ``object.__reduce_ex__()`` is called with an object that is faking
5197 its type.

5203
Georg Brandl7b9c5552007-03-12 14:30:05 +00005204- Bug #1678647: write a newline after printing an exception in any
5205 case, even when converting the value to a string failed.
5206
Georg Brandl871f1bc2007-03-12 13:17:36 +00005207- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208 its argument, if it exists. If not, it will work like before. This
5209 allows customizing the output of dir() in the presence of a
5210 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005211
Collin Winter276887b2007-03-12 16:11:39 +00005212- Patch #922167: Python no longer segfaults when faced with infinitely
5213 self-recursive reload() calls (as reported by bug #742342).
5214
Georg Brandl3ee81df2008-05-17 18:14:43 +00005215- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Patch #1491866: change the complex() constructor to allow
5219 parthensized forms. This means complex(repr(x)) now works instead of
5220 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005221
Georg Brandlaa2321b2007-03-07 00:40:28 +00005222- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005223 makes the filenames the warning module prints much more sensible
5224 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005225

Georg Brandl0fca97a2007-03-05 22:28:08 +00005237- Patch #1674228: when assigning a slice (old-style), check for the
5238 sq_ass_slice instead of the sq_slice slot.
5239
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240- When printing an unraisable error, don't print exceptions. before
5241 the name. This duplicates the behavior whening normally printing
5242 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005793- Patch #1530482: add pydoc.render_doc() which returns the

5808
Georg Brandl92a6bae2007-03-13 17:43:32 +00005809- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005810 are set for invalid interpolation sequences that would lead to
5811 errors on reading back those values.

5867 TestCase and TestSuite subclasses (not instances) are no longer
5868 accepted in TestSuite.addTest(). This should cause no
5869 incompatibility since it never made sense with ordinary subclasses
5870 -- the failure just occurred later, with a more cumbersome
5871 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006158 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006259- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006260 time so that opening a database previously created with the DB_DUP
6261 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6262 opens. Specifically: dictionary assignment to a DB object will
6263 replace all values for a given key when the database allows
6264 duplicate values. DB users should use DB.put(k, v) when they want
6265 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006544- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006545 periodic threadstate and signal checking in tight loops. By
6546 default, this option is turned-off. It should only be enabled in

6598-----
6599
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600- Unified naming convention for free lists and their limits. All free
6601 lists in Object/ are named ``free_list``, the counter ``numfree``

6603 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006604
Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6606 to ``PyTuple_SetItem``, it can be used to populate a brand new

6619
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6621 of w# format code incorrectly truncated the length to an int, even
6622 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6623 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006624
Georg Brandl3ee81df2008-05-17 18:14:43 +00006625- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6646- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6647 outside of pystate.c and should not be necessary.
6648
Georg Brandl3ee81df2008-05-17 18:14:43 +00006649- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6650 absolute imports. In earlier versions they might have used relative
6651 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006652
Georg Brandl3ee81df2008-05-17 18:14:43 +00006653- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6654 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006655
Georg Brandl3ee81df2008-05-17 18:14:43 +00006656- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

6666 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006667

Georg Brandl3ee81df2008-05-17 18:14:43 +00006681- Removed the macfs module. It had been deprecated since Python 2.5.
6682 This lead to the deprecation of macostools.touched() as it relied
6683 solely on macfs and was a no-op under OS X.
