438 This prevents user-created self-referencing ordered dictionaries from
439 becoming permanently uncollectable GC garbage. The downside is that

915 objects. (1) The comparison could incorrectly return True in some cases
916 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
917 (2) The comparison raised an OverflowError for large integers, leading
918 to unpredictable exceptions when combining integers and complex objects
919 in sets or dicts.

Antoine Pitroufc69af12010-04-24 20:04:58 +00001165- Issue #5103: SSL handshake would ignore the socket timeout and block
1166 indefinitely if the other end didn't respond.
1167
Georg Brandlfee0f442010-05-22 21:26:21 +00001168- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001261 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001286- Issue #7301: Add environment variable $PYTHONWARNINGS.
1287
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001288- Issue #8329: Don't return the same lists from select.select when no fds are
1289 changed.
1290
Georg Brandlfee0f442010-05-22 21:26:21 +00001291- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001292 on 64-bit machines. The shift count for either left or right shift is
1293 permitted to be up to sys.maxsize.
1294
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001295- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00001301- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1302 with a non-empty format string. This is an effort to future-proof user
1303 code. If a derived class does not currently implement __format__ but later
1304 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001305 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001306 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001339- Issue #8257: The Decimal construct now accepts a float instance directly,
1340 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001341

Raymond Hettinger34c35b22010-04-03 10:22:00 +00001345- collections.Counter() now supports a subtract() method.
1346
Georg Brandlfee0f442010-05-22 21:26:21 +00001347- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001356- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1357 InvalidOperation instead of returning False. (Comparisons involving a quiet
1358 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1359 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001360
Georg Brandlfee0f442010-05-22 21:26:21 +00001361- Issue #2531: Comparison operations between floats and Decimal instances now
1362 return a result based on the numeric values of the operands; previously they
1363 returned an arbitrary result based on the relative ordering of id(float) and
1364 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001367 argument `-` which tells it to read files to compile from stdin. Each line is
1368 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001378- Comparisons using one of <, <=, >, >= between a complex instance and a
1379 Fractions instance now raise TypeError instead of returning True/False. This
1380 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1381 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001738- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1739 and add the additional members returned in an OSVERSIONINFOEX structure. The
1740 new members are service_pack_major, service_pack_minor, suite_mask, and

1744 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1745 returning NULL. The macro now returns a statically allocated empty string
1746 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00001791- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001792 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001793 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001798- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001799 file position when calling `truncate()`. It would previously change the file
1800 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001801 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1802

1804 class used to represent files stored inside an archive. The new
1805 implementation is significantly faster and can be wrapped in a
1806 ``io.BufferedReader`` object for more speedups. It also solves an issue
1807 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001818- Issue #7748: Since unicode values are supported for some metadata options in
1819 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1820 encoded string for them. This ensures that the upload and register commands
1821 send the correct values to PyPI without any error.

1897
Georg Brandlba83f822010-03-14 09:50:54 +00001898- The ``__complex__()`` method is now looked up on the class of instances to
1899 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001901- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1902 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1903
Mark Dickinson1b34d252010-01-01 17:27:30 +00001904- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001905 DeprecationWarning when passed a float argument where an integer was expected.
1906 These functions and methods now raise TypeError instead. The majority of the
1907 effects of this change are in the extension modules, but some core functions
1908 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1909 and many unicode/str methods.

1920 used to drop the time part of the result.
1921
Georg Brandlba83f822010-03-14 09:50:54 +00001922- Issue #1811: Improve accuracy and cross-platform consistency for true division
1923 of integers: the result of a/b is now correctly rounded for ints a and b (at
1924 least on IEEE 754 platforms), and in particular does not depend on the
1925 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001926
Georg Brandlba83f822010-03-14 09:50:54 +00001927- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1928 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1929 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001932 executables on OSX.
1933
Georg Brandlba83f822010-03-14 09:50:54 +00001934 These executables now work properly with the arch(1) command: ``arch -ppc
1935 python`` will start a universal binary version of python in PPC mode (unlike
1936 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001959 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002092- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2093 decimal string that's guaranteed to round back to x under correct rounding
2094 (with round-half-to-even rounding mode). Previously it gave a string based on

2096 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2097 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002099- Issue #7117: On almost all platforms: float-to-string and string-to-float
2100 conversions within Python are now correctly rounded. Places these conversions
2101 occur include: str for floats and complex numbers; the float and complex
2102 constructors; old-style and new-style numeric formatting; serialization and
2103 deserialization of floats and complex numbers using marshal, pickle and json;
2104 parsing of float and imaginary literals in Python code; Decimal-to-float
2105 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002106
Georg Brandlba83f822010-03-14 09:50:54 +00002107 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2108 providing correctly-rounded strtod and dtoa C functions. This code is
2109 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2110 the C compiler. There may be a small number of platforms on which correct
2111 operation of this code cannot be guaranteed, so the code is not used: notably,
2112 this applies to platforms where the C double format is not IEEE 754 binary64,
2113 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2114 and Python's configure script is unable to determine how to change the FPU
2115 precision. On these platforms conversions use the platform strtod and dtoa,
2116 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002118- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2119 uses the correctly-rounded string <-> float conversions described above (when
2120 available), and so produces correctly rounded results that will display nicely
2121 under the float repr. There are two related small changes: (1) round now
2122 accepts any class with an ``__index__()`` method for its second argument (but
2123 no longer accepts floats for the second argument), and (2) an excessively
2124 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2125 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002342- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002343 untrackable objects are not tracked by the garbage collector. This can reduce
2344 the size of collections and therefore the garbage collection overhead on
2345 long-running programs, depending on their particular use of datatypes.

2504 this code path is really executed because I cannot move to such directory on
2505 win2k)

2531 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00003348 for *nix machines for negative handles and large int handles. Without this
3349 check it is possible to segfault the interpreter.

Georg Brandlba83f822010-03-14 09:50:54 +00003368 the timestamp in the gzip stream. The default value remains the current time.

3703 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00003705 - If x is not an int, long or float, then packing x will always result in
3706 struct.error. Previously an x with an __int__ method could be packed by
3707 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3708 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3709 neither __int__ nor __long__, TypeError used to be raised (with a
3710 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3711 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00003713 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3714 argument with an __int__ method can be packed, but use of this feature
3715 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003908- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3910 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3911 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00004009 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4010 for catch_warnings() also led to an improvement in the raising of a
4011 DeprecationWarning related to warnings.warn_explicit().
4012

4038 without limit.
4039
Benjamin Peterson37346b22008-08-23 20:27:43 +00004040- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004077What's New in Python 2.6 beta 3?
4078================================
4079
Barry Warsaw07a4a382008-08-21 01:15:08 +00004080*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004081
4082Core and Builtins
4083-----------------
4084
Guido van Rossumf8402962008-08-20 15:01:50 +00004085- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4086 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4087 extensions do not automatically benefit from the class attribute
4088 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4089 to their tp_flags field if they care. This is a backwards
4090 compatibility feature; in 3.0, all types will use the cache by
4091 default.
4092
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004093- Keyword arguments can now follow starred arguments. (``f(a, *args,
4094 keyword=23)`` is now valid syntax.)
4095
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004096- ctypes function pointers that are COM methods have a boolean True
4097 value again.
4098
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004099- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4100 by denying s# to parse objects that have a releasebuffer procedure,
4101 and introducing s*.
4102
Georg Brandl1e13ea92008-08-11 09:07:59 +00004103- Issue #3537: Fix an assertion failure when an empty but presized dict
4104 object was stored in the freelist.
4105
Mark Dickinsonb6467572008-08-04 21:30:09 +00004106- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4107 ValueError consistently across platforms.
4108
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004109- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4110 (64bit Unix, for example), unichr() would truncate its argument and return
4111 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4112
Neal Norwitze7d8be82008-07-31 17:17:14 +00004113- Apply security patches from Apple.
4114
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004115- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4116 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4117
Antoine Pitrou92f82162008-07-25 22:22:08 +00004118- Issue #1819: function calls with several named parameters are now on
4119 average 35% faster (as measured by pybench).
4120
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004121- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4122 the python debugger steps into a class statement: the free variables (local
4123 variables defined in an outer scope) would be deleted from the outer scope.
4124
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004125- Issue #2620: Overflow checking when allocating or reallocating memory
4126 was not always being done properly in some python types and extension
4127 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4128 all been updated to perform better checks and places in the code that
4129 would previously leak memory on the error path when such an allocation
4130 failed have been fixed.
4131
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004132Library
4133-------
4134
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004135- Issue #3612: Added some missing basic types in ctypes.wintypes.
4136
Benjamin Petersone977ad42008-08-20 01:42:01 +00004137- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4138 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4139
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004140- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4141 version reported by these tools does not necessarily follow the python
4142 version numbering scheme, so the module is less strict when parsing it.
4143
Nick Coghlanf70385a2008-08-18 12:42:46 +00004144- Issue #2235: Added Py3k warnings for types which will become unhashable
4145 under the stricter __hash__ inheritance rules in 3.0. Several types
4146 which did not meet the rules for hash invariants and were already
4147 unhashable in 3.0 have now been explicitly flagged as unhashable in
4148 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4149 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4150
Brett Cannon88f801d2008-08-18 00:46:22 +00004151- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4159
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004160- Issue #3575: Incremental decoder's decode function now takes bytearray
4161 by using 's*' instead of 't#'.
4162
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004163- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004164 fails unicode conversion on 2nd parameter. (windows only)
4165
Georg Brandl222e2082010-08-01 22:27:39 +00004166- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004167 in a redirect.
4168

Brett Cannon721b1452008-08-16 22:00:27 +00004170 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004171
Facundo Batistaeb90b782008-08-16 14:44:07 +00004172- Issue #2776: fixed small issue when handling an URL with double slash
4173 after a 302 response in the case of not going through a proxy.
4174
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004175- Issue #2676: in the email package, content-type parsing was hanging on
4176 pathological input because of quadratic or exponential behaviour of a
4177 regular expression.
4178
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004179- Issue #3476: binary buffered reading through the new "io" library is now
4180 thread-safe.
4181
Brett Cannonbf3157b2008-08-14 05:00:03 +00004182- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4183 since mimetools itself is deprecated. Because modules are cached, all
4184 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4185
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004186- Issue #3134: shutil referenced undefined WindowsError symbol.
4187
Robert Schuppenies14646332008-08-10 11:01:53 +00004188- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4189 menu entries were not deleted.
4190
Brett Cannon83e81842008-08-09 23:30:55 +00004191- Copied the implementation of reduce() to _functools.reduce() to have a
4192 version that did not raise a DeprecationWarning under -3.
4193
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004194- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4195 a MemoryError rather than silently stop the iteration.
4196
Guido van Rossum59ce9012008-08-09 14:55:34 +00004197- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4198 to _sre.compile() will now be rejected. This should not affect anybody
4199 since the re.compile() function never generates invalid re-bytecode.
4200
Skip Montanaroa032bf42008-08-08 22:52:51 +00004201- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4202 upon first access it can be automatically initialized from the csv file if
4203 it wasn't initialized during instantiation.
4204
Brett Cannon3aa2a492008-08-06 22:28:09 +00004205- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4206 the reload() built-in has been removed.
4207
Brett Cannon7e30b672008-08-04 21:52:25 +00004208- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004209 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004220 asking for a specific length. This problem only affected files opened
4221 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004222

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004262- Issue #2235: the C API function PyObject_HashNotImplemented and its
4263 interaction with the tp_hash slot (added in 2.6b2) are now documented
4264
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004265- Issue #643841: The language reference now provides more detailed
4266 coverage of the lookup process for special methods. The disclaimers
4267 regarding lack of coverage of new-style classes have also been
4268 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004271What's New in Python 2.6 beta 2?
4272================================
4273
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004274*Release date: 17-Jul-2008*
4275
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004276Core and Builtins
4277-----------------
4278
Georg Brandl3e483f62008-07-16 22:57:41 +00004279- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4280 its methods now allow for items objects that can be converted to
4281 an integer using operator.index().
4282
Mark Dickinson64b7e502008-07-16 09:40:03 +00004283- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4284 produced a ValueError instead of giving the correct float.
4285
Eric Smitha5fa5a22008-07-16 00:11:49 +00004286- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4287 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4288
Mark Dickinson7103aa42008-07-15 19:08:33 +00004289- Issue #3008: the float type has a new instance method 'float.hex'
4290 and a new class method 'float.fromhex' to convert floating-point
4291 numbers to and from hexadecimal strings, respectively.
4292
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004293- Issue #2235: __hash__ is once again inherited by default. To allow
4294 collections.Hashable to remain meaningful in the presence of the
4295 default hash implementation (object.__hash__), it is now possible
4296 to explicit block inheritance of hash by setting __hash__=None at
4297 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4298 level.
4299
Nick Coghlanb028f502008-07-13 14:52:36 +00004300- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4301 the parent module cannot be found while performing an absolute import.
4302 This means that an incorrectly defined __package__ attribute will
4303 now only prevent relative imports in that module rather than causing
4304 all imports from that module to fail.
4305
Nick Coghlan14ff9942008-07-08 14:21:42 +00004306- Issue #2517: Allow unicode messages in Exceptions again by correctly
4307 bypassing the instance dictionary when looking up __unicode__ on
4308 new-style classes.
4309
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004310- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4311 set to a custom object whose write() method happens to install
4312 another file in sys.stdout.
4313
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004314- Issue #3088: Corrected a race condition in classes derived from
4315 threading.local: the first member set by a thread could be saved in
4316 another thread's dictionary.
4317
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004318- Issue #3004: Minor change to slice.indices(): the start and stop
4319 arguments are now treated identically, making the behaviour easier
4320 to describe and understand. For example, slice(None, -10,
4321 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4322 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4323 10, -1).
4324
Georg Brandl278fc502008-07-19 12:46:12 +00004325- Issue #3219: Calling a function with repeated keyword arguments,
4326 f(a=2, a=23), would not cause a syntax error. This was a regression
4327 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004328
Georg Brandl278fc502008-07-19 12:46:12 +00004329- Issue #2862: Make int and float freelist management consistent with
4330 other freelists. Changes their CompactFreeList apis into
4331 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004332

4334-------
4335
Thomas Heller57adf222008-08-14 19:10:48 +00004336- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4337 api functions without holding the GIL, which could lead to a fatal
4338 error when they failed.
4339
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004340- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4347
Jesse Noller13e9d582008-07-16 14:32:36 +00004348- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4349 ForkingPickler.register() to resolve conflict with ctypes.
4350
Vinay Sajip51e65192008-07-18 09:01:10 +00004351- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004352
Thomas Heller880f5292008-07-15 19:39:38 +00004353- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4354 a valid dlerror() message.
4355
Thomas Heller2bad6572008-07-15 17:19:50 +00004356- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4357 incomplete structure was created.
4358
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004359- Issue #3339: dummy_thread.acquire() should not return None.
4360
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004361- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4362
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004363- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004364
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004365- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4366 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004367 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004368 content-length. The problem had been corrected in the 2.4 branch, but never
4369 merged into trunk.
4370
Georg Brandle78fbcc2008-07-05 10:13:36 +00004371- Issue #2663: add filtering capability to shutil.copytree().
4372

4376
4377- Issue #1746: Correct handling of zipfile archive comments (previously
4378 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004379 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004380
Vinay Sajip51e65192008-07-18 09:01:10 +00004381- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004382 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004383
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004384- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4385 handling is now the same as that of other special attributes like __name__).
4386
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004387- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4388 removal in Python 3.0 in favor of urllib2.urlopen().

4400
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00004401- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00004839- Issue #1631171: Re-implement the 'warnings' module in C (the
4840 original Python code has been kept as backup). This will allow for
4841 using the 'warning's machinery in such places as the parser where
4842 use of pure Python code is not possible. Both the ``showarning()``
4843 and ``formatwarning()`` gain an optional 'line' argument which is
4844 not called by default for backwards-compatibility reasons. Setting
4845 ``warnings.showwarning()`` to an implementation that lacks support
4846 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004909- Issue #2550: The approach used by client/server code for obtaining
4910 ports to listen on in network-oriented tests has been refined in an
4911 effort to facilitate running multiple instances of the entire
4912 regression test suite in parallel without issue.
4913 test_support.bind_port() has been fixed such that it will always
4914 return a unique port -- which wasn't always the case with the
4915 previous implementation, especially if socket options had been set
4916 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4917 new implementation of bind_port() will actually raise an exception
4918 if it is passed an AF_INET/SOCK_STREAM socket with either the
4919 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4920 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4921 the socket it's been passed. This currently only applies to
4922 Windows. This option prevents any other sockets from binding to the
4923 host/port we've bound to, thus removing the possibility of the
4924 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4925 when a second SOCK_STREAM socket binds and accepts to a host/port
4926 that's already been bound by another socket. The optional preferred
4927 port parameter to bind_port() has been removed. Under no
4928 circumstances should tests be hard coding ports!
4929
4930 test_support.find_unused_port() has also been introduced, which will
4931 pass a temporary socket object to bind_port() in order to obtain an
4932 unused port. The temporary socket object is then closed and
4933 deleted, and the port is returned. This method should only be used
4934 for obtaining an unused port in order to pass to an external program
4935 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4936 a parameter to a server-oriented class that doesn't give you direct
4937 access to the underlying socket used.
4938
4939 Finally, test_support.HOST has been introduced, which should be used
4940 for the host argument of any relevant socket calls (i.e. bind and
4941 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004942
4943 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004945 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4946 test_asynchat and test_socket_ssl.
4947
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948 It is now possible for multiple instances of the regression test
4949 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005228- Added the future_builtins module, which contains hex() and oct().
5229 These are the PEP 3127 version of these functions, designed to be
5230 compatible with the hex() and oct() builtins from Python 3.0. They
5231 differ slightly in their output formats from the existing, unchanged
5232 Python 2.6 builtins. The expected usage of the future_builtins
5233 module is:
5234 from future_builtins import hex, oct
5235
Eric Smith7ef40bf2008-02-20 23:34:22 +00005236- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5237 exponents for exponents with absolute value < 100. Follows C99
5238 standard. This is a change on Windows, which would use 3 digits.
5239 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5240 so that any alterations it does to the resulting string will be
5241 available in stringlib/formatter.h (for float.__format__).
5242
Eric Smith5a3c1352008-02-19 13:21:56 +00005243- Implemented PEP 3101, Advanced String Formatting. This adds a new
5244 builtin format(); a format() method for str and unicode; a
5245 __format__() method to object, str, unicode, int, long, float, and
5246 datetime; the class string.Formatter; and the C API
5247 PyObject_Format().
5248
Georg Brandl3ee81df2008-05-17 18:14:43 +00005249- Fixed several potential crashes, all caused by specially crafted
5250 __del__ methods exploiting objects in temporarily inconsistent
5251 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005252
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005253- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 prevent a possible crash: an Abstract Base Class would try to access
5255 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005256

Georg Brandl3ee81df2008-05-17 18:14:43 +00005260- Clear all free lists during a gc.collect() of the highest generation
5261 in order to allow pymalloc to free more arenas. Python may give back
5262 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005263
Georg Brandl3ee81df2008-05-17 18:14:43 +00005264- Issue #2045: Fix an infinite recursion triggered when printing a
5265 subclass of collections.defaultdict, if its default_factory is set
5266 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005267
Christian Heimesf75dbef2008-02-08 00:11:31 +00005268- Fixed a minor memory leak in dictobject.c. The content of the free
5269 list was not freed on interpreter shutdown.
5270
Georg Brandl21e99f42010-03-07 15:23:59 +00005271- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005272 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005273
Georg Brandl3ee81df2008-05-17 18:14:43 +00005274- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5275 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005276 to compact the internal free lists of pre-allocted ints and floats.
5277
Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5279 calls. Python expected the return type int but the fork familie
5280 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005281
Georg Brandl3ee81df2008-05-17 18:14:43 +00005282- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5283 appear in the same code unit.

5292 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005293
Georg Brandl3ee81df2008-05-17 18:14:43 +00005294- Patch #1473257: generator objects gain a gi_code attribute. This is
5295 the same object as the func_code attribute of the function that
5296 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005297
Georg Brandl3ee81df2008-05-17 18:14:43 +00005298- Issue #1920: "while 0" statements were completely removed by the
5299 compiler, even in the presence of an "else" clause, which is
5300 supposed to be run when the condition is false. Now the compiler
5301 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005302
Guido van Rossumeead05f2008-01-24 18:21:02 +00005303- A few crashers fixed: weakref_in_del.py (issue #1377858);
5304 loosing_dict_ref.py (issue #1303614, test67.py);
5305 borrowed_ref_[34].py (not in tracker).

5310
Georg Brandl3ee81df2008-05-17 18:14:43 +00005311- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005312 several extension methods and modules do not work without unicode
5313 support.
5314
Georg Brandl26543b12008-01-21 18:36:51 +00005315- Issue #1882: when compiling code from a string, encoding cookies in the

5317
Georg Brandl14404b62008-01-19 19:27:05 +00005318- Issue #1679: "0x" was taken as a valid integer literal.
5319
Georg Brandl6caad7d2008-01-26 14:19:22 +00005320- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005321 added.
5322
Christian Heimesc94e2b52008-01-14 04:13:37 +00005323- sys.float_info / PyFloat_GetInfo: The floating point information
5324 object was converted from a dict to a specialized structseq object.
5325
Georg Brandl3ee81df2008-05-17 18:14:43 +00005326- Patch #1816: Added sys.flags structseq. It exposes the status of
5327 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005328
Georg Brandl3ee81df2008-05-17 18:14:43 +00005329- Objects/structseq.c: Implemented new structseq representation. The
5330 patch makes structseqs (e.g. the return value of os.stat) more
5331 readable.

Georg Brandlaed6c662008-01-07 17:25:53 +00005339- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5340
Georg Brandl3ee81df2008-05-17 18:14:43 +00005341- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5342 envvar and sys.dont_write_bytecode attribute. All these can be set
5343 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005345- Improve some exception messages when Windows fails to load an
5346 extension module. Now we get for example '%1 is not a valid Win32
5347 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005354- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355 and INF. float("nan"), float("inf") and float("-inf") now work on
5356 every platform with IEEE 754 semantics.

5360 dictionary size. There is a new opcode, STORE_MAP, for adding
5361 entries to the dictionary.

5391 file can now be directly executed by passing their name to the
5392 interpreter. The directory/zipfile is automatically inserted as the
5393 first entry in sys.path.

5404
Georg Brandl21e99f42010-03-07 15:23:59 +00005405- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5407 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005408
Georg Brandl3ee81df2008-05-17 18:14:43 +00005409- Issue #1686386: Tuple's tp_repr did not take into account the
5410 possibility of having a self-referential tuple, which is possible
5411 from C code. Nor did object's tp_str consider that a type's tp_str
5412 could do something that could lead to an inifinite recursion.
5413 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5414 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Issue #1164: It was possible to trigger deadlock when using the
5417 'print' statement to write to a file since the GIL was not released
5418 as needed. Now PyObject_Print() does the right thing along with
5419 various tp_print implementations of the built-in types and those in
5420 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005421
Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005429- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005430 PyObject_Call() never calling back out to Python code to trigger
5431 recursion depth updates/checks. Required the creation of a static
5432 RuntimeError instance in case normalizing an exception put the
5433 recursion check value past its limit. Fixes crashers
5434 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005449- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450 __*__ attributes. (Some already existed, e.g., __doc__ and
5451 __name__.)

5455
Georg Brandl2134e752007-05-21 20:34:16 +00005456- Patch #1686487: you can now pass any mapping after '**' in function
5457 calls.
5458
Collin Winter62903052007-05-18 23:11:24 +00005459- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005460 "except E as target:". This is to provide forwards compatibility
5461 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005468- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005469 setting a plain string, ie don't expand to single letter identifiers.
5470
Raymond Hettinger13936692007-04-11 18:40:58 +00005471- Request #1191699: Slices can now be pickled.
5472
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005473- Request #1193128: str.translate() now allows a None argument for
5474 translations that only remove characters without re-mapping the
5475 remaining characters.
5476
Georg Brandl5cb76c12007-03-21 09:00:39 +00005477- Patch #1682205: a TypeError while unpacking an iterable is no longer

5481
Guido van Rossum143b5642007-03-23 04:58:42 +00005482- Bug #1683368: The object.__init__() and object.__new__() methods are
5483 now stricter in rejecting excess arguments. The only time when
5484 either allows excess arguments is when it is not overridden and the
5485 other one is. For backwards compatibility, when both are
5486 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005487 warning later). Also, type.__init__() insists on the same signature
5488 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005490- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5491 object to complex using its __complex__() method before falling back
5492 to the __float__() method. Therefore, the functions in the cmath
5493 module now can operate on objects that define a __complex__()
5494 method.

5511
Georg Brandl7b9c5552007-03-12 14:30:05 +00005512- Bug #1678647: write a newline after printing an exception in any
5513 case, even when converting the value to a string failed.
5514
Georg Brandl871f1bc2007-03-12 13:17:36 +00005515- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005516 its argument, if it exists. If not, it will work like before. This
5517 allows customizing the output of dir() in the presence of a
5518 __getattr__().

5527 parthensized forms. This means complex(repr(x)) now works instead of
5528 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005529
Georg Brandlaa2321b2007-03-07 00:40:28 +00005530- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531 makes the filenames the warning module prints much more sensible
5532 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005545- Patch #1674228: when assigning a slice (old-style), check for the
5546 sq_ass_slice instead of the sq_slice slot.
5547
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548- When printing an unraisable error, don't print exceptions. before
5549 the name. This duplicates the behavior whening normally printing
5550 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006083 AttributeError instead of an IOError when the server's response
6084 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006085

6100
Georg Brandl3ee81df2008-05-17 18:14:43 +00006101- Patch #1530482: add pydoc.render_doc() which returns the

6116
Georg Brandl92a6bae2007-03-13 17:43:32 +00006117- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006118 are set for invalid interpolation sequences that would lead to
6119 errors on reading back those values.

6173
Georg Brandl3ee81df2008-05-17 18:14:43 +00006174- unittest now verifies more of its assumptions. In particular,
6175 TestCase and TestSuite subclasses (not instances) are no longer
6176 accepted in TestSuite.addTest(). This should cause no
6177 incompatibility since it never made sense with ordinary subclasses
6178 -- the failure just occurred later, with a more cumbersome
6179 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006567- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568 time so that opening a database previously created with the DB_DUP
6569 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6570 opens. Specifically: dictionary assignment to a DB object will
6571 replace all values for a given key when the database allows
6572 duplicate values. DB users should use DB.put(k, v) when they want
6573 to store duplicates; not DB[k] = v.

6580 characters with ASCII value less than 32. Also, it correctly quotes
6581 dots only if they occur on a single line, as opposed to the previous
6582 behavior of quoting dots if they are the second character of any
6583 line.
