Raymond Hettinger20397532010-09-12 02:11:45 +0000415- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
416 This prevents user-created self-referencing ordered dictionaries from
417 becoming permanently uncollectable GC garbage. The downside is that
418 removing __del__ means that the internal doubly-linked list has to wait for
419 GC collection rather than freeing memory immediately when the refcnt drops
420 to zero.

429 original error is re-raised.
430

452 character years even if the message contains RFC822 two character years.
453
Daniel Stutzbach91287322010-08-24 21:09:30 +0000454- Issue #8750: Fixed MutableSet's methods to correctly handle

469 ignored by the buffered IO layer anymore.
470
Benjamin Peterson52c36052010-08-21 03:03:22 +0000471- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

473
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000474- Issue #9626: the view methods for collections.OrderedDict() were returning

488 when the underlying raw IO channel was e.g. a socket. Report and original
489 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001239 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

1262-----------------
1263
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001264- Issue #7301: Add environment variable $PYTHONWARNINGS.
1265
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001266- Issue #8329: Don't return the same lists from select.select when no fds are
1267 changed.
1268
Georg Brandlfee0f442010-05-22 21:26:21 +00001269- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001270 on 64-bit machines. The shift count for either left or right shift is
1271 permitted to be up to sys.maxsize.
1272
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001273- Ensure that tokenization of identifiers is not affected by locale.

1278
Georg Brandlfee0f442010-05-22 21:26:21 +00001279- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1280 with a non-empty format string. This is an effort to future-proof user
1281 code. If a derived class does not currently implement __format__ but later
1282 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001283 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001284 Python 3.3 and it will be an error in Python 3.4.

1316
Georg Brandlfee0f442010-05-22 21:26:21 +00001317- Issue #8257: The Decimal construct now accepts a float instance directly,
1318 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001319
1320 >>> Decimal(1.1)
1321 Decimal('1.100000000000000088817841970012523233890533447265625')
1322
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001323- collections.Counter() now supports a subtract() method.
1324
Georg Brandlfee0f442010-05-22 21:26:21 +00001325- The functools module now has a total_ordering() class decorator to simplify
1326 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001334- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1335 InvalidOperation instead of returning False. (Comparisons involving a quiet
1336 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1337 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001338
Georg Brandlfee0f442010-05-22 21:26:21 +00001339- Issue #2531: Comparison operations between floats and Decimal instances now
1340 return a result based on the numeric values of the operands; previously they
1341 returned an arbitrary result based on the relative ordering of id(float) and
1342 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001343
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001344- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001345 argument `-` which tells it to read files to compile from stdin. Each line is
1346 read on demand and the named file is compiled immediately. (Original patch by
1347 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001352- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1353 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001354 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001355
Georg Brandlfee0f442010-05-22 21:26:21 +00001356- Comparisons using one of <, <=, >, >= between a complex instance and a
1357 Fractions instance now raise TypeError instead of returning True/False. This
1358 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1359 <=> complex, and complex <=> complex comparisons.

1722 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1723 returning NULL. The macro now returns a statically allocated empty string

Georg Brandlba83f822010-03-14 09:50:54 +00001777 file position when calling `truncate()`. It would previously change the file
1778 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001779 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1782 class used to represent files stored inside an archive. The new
1783 implementation is significantly faster and can be wrapped in a
1784 ``io.BufferedReader`` object for more speedups. It also solves an issue
1785 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001796- Issue #7748: Since unicode values are supported for some metadata options in
1797 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1798 encoded string for them. This ensures that the upload and register commands
1799 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001876- The ``__complex__()`` method is now looked up on the class of instances to
1877 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001879- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1880 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1881
Mark Dickinson1b34d252010-01-01 17:27:30 +00001882- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001883 DeprecationWarning when passed a float argument where an integer was expected.
1884 These functions and methods now raise TypeError instead. The majority of the
1885 effects of this change are in the extension modules, but some core functions
1886 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1887 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001897- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1898 used to drop the time part of the result.
1899
Georg Brandlba83f822010-03-14 09:50:54 +00001900- Issue #1811: Improve accuracy and cross-platform consistency for true division
1901 of integers: the result of a/b is now correctly rounded for ints a and b (at
1902 least on IEEE 754 platforms), and in particular does not depend on the
1903 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001904
Georg Brandlba83f822010-03-14 09:50:54 +00001905- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1906 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1907 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001908

Ronald Oussoren92919a62009-12-24 13:30:58 +00001910 executables on OSX.
1911
Georg Brandlba83f822010-03-14 09:50:54 +00001912 These executables now work properly with the arch(1) command: ``arch -ppc
1913 python`` will start a universal binary version of python in PPC mode (unlike
1914 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001915
Georg Brandlba83f822010-03-14 09:50:54 +00001916- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1917 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00001936- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001937 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1938 alternative to cPickle if you care about performance. Patch by Florent

1974 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1975 the same as passing no argument.
1976

Georg Brandlba83f822010-03-14 09:50:54 +00002070- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2071 decimal string that's guaranteed to round back to x under correct rounding
2072 (with round-half-to-even rounding mode). Previously it gave a string based on
2073 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2074 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2075 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002076
Georg Brandlba83f822010-03-14 09:50:54 +00002077- Issue #7117: On almost all platforms: float-to-string and string-to-float
2078 conversions within Python are now correctly rounded. Places these conversions
2079 occur include: str for floats and complex numbers; the float and complex
2080 constructors; old-style and new-style numeric formatting; serialization and
2081 deserialization of floats and complex numbers using marshal, pickle and json;
2082 parsing of float and imaginary literals in Python code; Decimal-to-float
2083 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002084
Georg Brandlba83f822010-03-14 09:50:54 +00002085 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2086 providing correctly-rounded strtod and dtoa C functions. This code is
2087 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2088 the C compiler. There may be a small number of platforms on which correct
2089 operation of this code cannot be guaranteed, so the code is not used: notably,
2090 this applies to platforms where the C double format is not IEEE 754 binary64,
2091 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2092 and Python's configure script is unable to determine how to change the FPU
2093 precision. On these platforms conversions use the platform strtod and dtoa,
2094 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002096- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2097 uses the correctly-rounded string <-> float conversions described above (when
2098 available), and so produces correctly rounded results that will display nicely
2099 under the float repr. There are two related small changes: (1) round now
2100 accepts any class with an ``__index__()`` method for its second argument (but
2101 no longer accepts floats for the second argument), and (2) an excessively
2102 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2103 raises an exception.

2106
Georg Brandlba83f822010-03-14 09:50:54 +00002107- Fix several issues with ``compile()``. The input can now contain Windows and

2453
Georg Brandlba83f822010-03-14 09:50:54 +00002454- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

Georg Brandlba83f822010-03-14 09:50:54 +00002480- On windows, ``os.chdir()`` given unicode was not working if
2481 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2482 this code path is really executed because I cannot move to such directory on
2483 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002485- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2486 element is temporarily replaced with an equivalent frozenset. But the
2487 eventual KeyError would always report the empty ``frozenset()`` as the missing

2509 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Walter Dörwald726ba8e2009-05-06 14:32:35 +00002513- Issue #3739: The unicode-internal encoder now reports the number of characters

3885
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003886- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3887 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3888 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3889 ``printf`` function, whereas PyString_FromFormat has an independent
3890 implementation and uses "%zd" on all platforms for size_t values.
3891 This makes a difference on win64, where ``printf`` needs "%Id" to display
3892 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003912 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3913 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3914 when given a tuple of classes as second argument, were looking up
3915 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3916 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003987 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3988 for catch_warnings() also led to an improvement in the raising of a
3989 DeprecationWarning related to warnings.warn_explicit().
3990
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003991- The deprecation warnings for the old camelCase threading API were removed.

4013
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004014- Issue #2975: When compiling several extension modules with Visual Studio 2008
4015 from the same python interpreter, some environment variables would grow
4016 without limit.
4017
Benjamin Peterson37346b22008-08-23 20:27:43 +00004018- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4019 exploitation of poor argument checking.
4020
Gerhard Häringef2276b2008-09-12 13:54:06 +00004021- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004055What's New in Python 2.6 beta 3?
4056================================
4057
Barry Warsaw07a4a382008-08-21 01:15:08 +00004058*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004059
4060Core and Builtins
4061-----------------
4062
Guido van Rossumf8402962008-08-20 15:01:50 +00004063- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4064 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4065 extensions do not automatically benefit from the class attribute
4066 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4067 to their tp_flags field if they care. This is a backwards
4068 compatibility feature; in 3.0, all types will use the cache by
4069 default.
4070
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004071- Keyword arguments can now follow starred arguments. (``f(a, *args,
4072 keyword=23)`` is now valid syntax.)
4073
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004074- ctypes function pointers that are COM methods have a boolean True
4075 value again.
4076
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004077- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4078 by denying s# to parse objects that have a releasebuffer procedure,
4079 and introducing s*.
4080
Georg Brandl1e13ea92008-08-11 09:07:59 +00004081- Issue #3537: Fix an assertion failure when an empty but presized dict
4082 object was stored in the freelist.
4083
Mark Dickinsonb6467572008-08-04 21:30:09 +00004084- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4085 ValueError consistently across platforms.
4086
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004087- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4088 (64bit Unix, for example), unichr() would truncate its argument and return
4089 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4090
Neal Norwitze7d8be82008-07-31 17:17:14 +00004091- Apply security patches from Apple.
4092
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004093- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4094 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4095
Antoine Pitrou92f82162008-07-25 22:22:08 +00004096- Issue #1819: function calls with several named parameters are now on
4097 average 35% faster (as measured by pybench).
4098
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004099- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4100 the python debugger steps into a class statement: the free variables (local
4101 variables defined in an outer scope) would be deleted from the outer scope.
4102
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004103- Issue #2620: Overflow checking when allocating or reallocating memory
4104 was not always being done properly in some python types and extension
4105 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4106 all been updated to perform better checks and places in the code that
4107 would previously leak memory on the error path when such an allocation
4108 failed have been fixed.
4109
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004110Library
4111-------
4112
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004113- Issue #3612: Added some missing basic types in ctypes.wintypes.
4114
Benjamin Petersone977ad42008-08-20 01:42:01 +00004115- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4116 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4117
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004118- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4119 version reported by these tools does not necessarily follow the python
4120 version numbering scheme, so the module is less strict when parsing it.
4121
Nick Coghlanf70385a2008-08-18 12:42:46 +00004122- Issue #2235: Added Py3k warnings for types which will become unhashable
4123 under the stricter __hash__ inheritance rules in 3.0. Several types
4124 which did not meet the rules for hash invariants and were already
4125 unhashable in 3.0 have now been explicitly flagged as unhashable in
4126 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4127 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4128
Brett Cannon88f801d2008-08-18 00:46:22 +00004129- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004136- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4137
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004138- Issue #3575: Incremental decoder's decode function now takes bytearray
4139 by using 's*' instead of 't#'.
4140
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004141- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004142 fails unicode conversion on 2nd parameter. (windows only)
4143
Georg Brandl222e2082010-08-01 22:27:39 +00004144- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004145 in a redirect.
4146
Brett Cannonabe423e2008-08-16 21:47:07 +00004147- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004148 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004149
Facundo Batistaeb90b782008-08-16 14:44:07 +00004150- Issue #2776: fixed small issue when handling an URL with double slash
4151 after a 302 response in the case of not going through a proxy.
4152
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004153- Issue #2676: in the email package, content-type parsing was hanging on
4154 pathological input because of quadratic or exponential behaviour of a
4155 regular expression.
4156
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004157- Issue #3476: binary buffered reading through the new "io" library is now
4158 thread-safe.
4159
Brett Cannonbf3157b2008-08-14 05:00:03 +00004160- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4161 since mimetools itself is deprecated. Because modules are cached, all
4162 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4163
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004164- Issue #3134: shutil referenced undefined WindowsError symbol.
4165
Robert Schuppenies14646332008-08-10 11:01:53 +00004166- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4167 menu entries were not deleted.
4168
Brett Cannon83e81842008-08-09 23:30:55 +00004169- Copied the implementation of reduce() to _functools.reduce() to have a
4170 version that did not raise a DeprecationWarning under -3.
4171
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004172- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4173 a MemoryError rather than silently stop the iteration.
4174
Guido van Rossum59ce9012008-08-09 14:55:34 +00004175- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4176 to _sre.compile() will now be rejected. This should not affect anybody
4177 since the re.compile() function never generates invalid re-bytecode.
4178
Skip Montanaroa032bf42008-08-08 22:52:51 +00004179- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4180 upon first access it can be automatically initialized from the csv file if
4181 it wasn't initialized during instantiation.
4182
Brett Cannon3aa2a492008-08-06 22:28:09 +00004183- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4184 the reload() built-in has been removed.
4185
Brett Cannon7e30b672008-08-04 21:52:25 +00004186- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004187 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004198 asking for a specific length. This problem only affected files opened
4199 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004200

4225 file name rather than a ZipInfo instance, so files are extracted with
4226 mode 0600 rather than 000 under Unix.
4227

4245 regarding lack of coverage of new-style classes have also been
4246 removed, since the coverage is now fairly reasonable.

Mark Dickinson64b7e502008-07-16 09:40:03 +00004261- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4262 produced a ValueError instead of giving the correct float.
4263
Eric Smitha5fa5a22008-07-16 00:11:49 +00004264- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4265 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4266
Mark Dickinson7103aa42008-07-15 19:08:33 +00004267- Issue #3008: the float type has a new instance method 'float.hex'
4268 and a new class method 'float.fromhex' to convert floating-point
4269 numbers to and from hexadecimal strings, respectively.
4270
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004271- Issue #2235: __hash__ is once again inherited by default. To allow
4272 collections.Hashable to remain meaningful in the presence of the
4273 default hash implementation (object.__hash__), it is now possible
4274 to explicit block inheritance of hash by setting __hash__=None at
4275 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4276 level.
4277
Nick Coghlanb028f502008-07-13 14:52:36 +00004278- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4279 the parent module cannot be found while performing an absolute import.
4280 This means that an incorrectly defined __package__ attribute will
4281 now only prevent relative imports in that module rather than causing
4282 all imports from that module to fail.
4283
Nick Coghlan14ff9942008-07-08 14:21:42 +00004284- Issue #2517: Allow unicode messages in Exceptions again by correctly

4294 another thread's dictionary.
4295
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004296- Issue #3004: Minor change to slice.indices(): the start and stop
4297 arguments are now treated identically, making the behaviour easier
4298 to describe and understand. For example, slice(None, -10,
4299 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4300 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4301 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00004303- Issue #3219: Calling a function with repeated keyword arguments,
4304 f(a=2, a=23), would not cause a syntax error. This was a regression
4305 from 2.4 caused by the switch to the new compiler.

4344 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004345 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00004817- Issue #1631171: Re-implement the 'warnings' module in C (the
4818 original Python code has been kept as backup). This will allow for
4819 using the 'warning's machinery in such places as the parser where
4820 use of pure Python code is not possible. Both the ``showarning()``
4821 and ``formatwarning()`` gain an optional 'line' argument which is
4822 not called by default for backwards-compatibility reasons. Setting
4823 ``warnings.showwarning()`` to an implementation that lacks support
4824 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Issue #2550: The approach used by client/server code for obtaining
4888 ports to listen on in network-oriented tests has been refined in an
4889 effort to facilitate running multiple instances of the entire
4890 regression test suite in parallel without issue.
4891 test_support.bind_port() has been fixed such that it will always
4892 return a unique port -- which wasn't always the case with the
4893 previous implementation, especially if socket options had been set
4894 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4895 new implementation of bind_port() will actually raise an exception
4896 if it is passed an AF_INET/SOCK_STREAM socket with either the
4897 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4898 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4899 the socket it's been passed. This currently only applies to
4900 Windows. This option prevents any other sockets from binding to the
4901 host/port we've bound to, thus removing the possibility of the
4902 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4903 when a second SOCK_STREAM socket binds and accepts to a host/port
4904 that's already been bound by another socket. The optional preferred
4905 port parameter to bind_port() has been removed. Under no
4906 circumstances should tests be hard coding ports!
4907
4908 test_support.find_unused_port() has also been introduced, which will
4909 pass a temporary socket object to bind_port() in order to obtain an
4910 unused port. The temporary socket object is then closed and
4911 deleted, and the port is returned. This method should only be used
4912 for obtaining an unused port in order to pass to an external program
4913 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4914 a parameter to a server-oriented class that doesn't give you direct
4915 access to the underlying socket used.
4916
4917 Finally, test_support.HOST has been introduced, which should be used
4918 for the host argument of any relevant socket calls (i.e. bind and
4919 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004920
4921 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004922 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004923 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4924 test_asynchat and test_socket_ssl.
4925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926 It is now possible for multiple instances of the regression test
4927 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005206- Added the future_builtins module, which contains hex() and oct().
5207 These are the PEP 3127 version of these functions, designed to be
5208 compatible with the hex() and oct() builtins from Python 3.0. They
5209 differ slightly in their output formats from the existing, unchanged
5210 Python 2.6 builtins. The expected usage of the future_builtins
5211 module is:
5212 from future_builtins import hex, oct
5213
Eric Smith7ef40bf2008-02-20 23:34:22 +00005214- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5215 exponents for exponents with absolute value < 100. Follows C99
5216 standard. This is a change on Windows, which would use 3 digits.
5217 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5218 so that any alterations it does to the resulting string will be
5219 available in stringlib/formatter.h (for float.__format__).
5220
Eric Smith5a3c1352008-02-19 13:21:56 +00005221- Implemented PEP 3101, Advanced String Formatting. This adds a new
5222 builtin format(); a format() method for str and unicode; a
5223 __format__() method to object, str, unicode, int, long, float, and
5224 datetime; the class string.Formatter; and the C API
5225 PyObject_Format().
5226
Georg Brandl3ee81df2008-05-17 18:14:43 +00005227- Fixed several potential crashes, all caused by specially crafted
5228 __del__ methods exploiting objects in temporarily inconsistent
5229 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005230
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005231- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005232 prevent a possible crash: an Abstract Base Class would try to access
5233 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005234
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235- Fixed repr() and str() of complex numbers with infinity or nan as
5236 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005238- Clear all free lists during a gc.collect() of the highest generation
5239 in order to allow pymalloc to free more arenas. Python may give back
5240 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005241
Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- Issue #2045: Fix an infinite recursion triggered when printing a
5243 subclass of collections.defaultdict, if its default_factory is set
5244 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005245
Christian Heimesf75dbef2008-02-08 00:11:31 +00005246- Fixed a minor memory leak in dictobject.c. The content of the free
5247 list was not freed on interpreter shutdown.
5248
Georg Brandl21e99f42010-03-07 15:23:59 +00005249- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005251
Georg Brandl3ee81df2008-05-17 18:14:43 +00005252- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5253 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005254 to compact the internal free lists of pre-allocted ints and floats.
5255
Georg Brandl3ee81df2008-05-17 18:14:43 +00005256- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5257 calls. Python expected the return type int but the fork familie
5258 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005259
Georg Brandl3ee81df2008-05-17 18:14:43 +00005260- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5261 appear in the same code unit.

5270 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005271
Georg Brandl3ee81df2008-05-17 18:14:43 +00005272- Patch #1473257: generator objects gain a gi_code attribute. This is
5273 the same object as the func_code attribute of the function that
5274 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005275
Georg Brandl3ee81df2008-05-17 18:14:43 +00005276- Issue #1920: "while 0" statements were completely removed by the
5277 compiler, even in the presence of an "else" clause, which is
5278 supposed to be run when the condition is false. Now the compiler
5279 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005280
Guido van Rossumeead05f2008-01-24 18:21:02 +00005281- A few crashers fixed: weakref_in_del.py (issue #1377858);
5282 loosing_dict_ref.py (issue #1303614, test67.py);
5283 borrowed_ref_[34].py (not in tracker).
5284
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005285- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005286 suppressed while an extension is loaded by calling SetErrorMode in
5287 dynload_win.c. The error is still reported properly.
5288
Georg Brandl3ee81df2008-05-17 18:14:43 +00005289- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005290 several extension methods and modules do not work without unicode
5291 support.
5292
Georg Brandl26543b12008-01-21 18:36:51 +00005293- Issue #1882: when compiling code from a string, encoding cookies in the
5294 second line of code were not always recognized correctly.
5295
Georg Brandl14404b62008-01-19 19:27:05 +00005296- Issue #1679: "0x" was taken as a valid integer literal.
5297
Georg Brandl6caad7d2008-01-26 14:19:22 +00005298- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005299 added.
5300
Christian Heimesc94e2b52008-01-14 04:13:37 +00005301- sys.float_info / PyFloat_GetInfo: The floating point information
5302 object was converted from a dict to a specialized structseq object.
5303
Georg Brandl3ee81df2008-05-17 18:14:43 +00005304- Patch #1816: Added sys.flags structseq. It exposes the status of
5305 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005306
Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Objects/structseq.c: Implemented new structseq representation. The
5308 patch makes structseqs (e.g. the return value of os.stat) more
5309 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005310
Georg Brandl3ee81df2008-05-17 18:14:43 +00005311- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005323- Improve some exception messages when Windows fails to load an
5324 extension module. Now we get for example '%1 is not a valid Win32
5325 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005332- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005333 and INF. float("nan"), float("inf") and float("-inf") now work on
5334 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005336- Compiler now generates simpler and faster code for dictionary
5337 literals. The oparg for BUILD_MAP now indicates an estimated
5338 dictionary size. There is a new opcode, STORE_MAP, for adding
5339 entries to the dictionary.

5369 file can now be directly executed by passing their name to the
5370 interpreter. The directory/zipfile is automatically inserted as the
5371 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005373- Issue #1265: Fix a problem with sys.settrace, if the tracing
5374 function uses a generator expression when at the same time the
5375 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005376

5382
Georg Brandl21e99f42010-03-07 15:23:59 +00005383- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005384 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5385 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005386
Georg Brandl3ee81df2008-05-17 18:14:43 +00005387- Issue #1686386: Tuple's tp_repr did not take into account the
5388 possibility of having a self-referential tuple, which is possible
5389 from C code. Nor did object's tp_str consider that a type's tp_str
5390 could do something that could lead to an inifinite recursion.
5391 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5392 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005393
Georg Brandl3ee81df2008-05-17 18:14:43 +00005394- Issue #1164: It was possible to trigger deadlock when using the
5395 'print' statement to write to a file since the GIL was not released
5396 as needed. Now PyObject_Print() does the right thing along with
5397 various tp_print implementations of the built-in types and those in
5398 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005399
Georg Brandl3ee81df2008-05-17 18:14:43 +00005400- Issue #1147: Exceptions were directly allowing string exceptions in
5401 their throw() method even though string exceptions no longer
5402 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005404- Issue #1096: Prevent a segfault from getting the repr of a very
5405 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005406
Brett Cannon1e534b52007-09-07 04:18:30 +00005407- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005408 PyObject_Call() never calling back out to Python code to trigger
5409 recursion depth updates/checks. Required the creation of a static
5410 RuntimeError instance in case normalizing an exception put the
5411 recursion check value past its limit. Fixes crashers
5412 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005413

Neal Norwitz0ac60192007-05-27 04:08:54 +00005427- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005428 __*__ attributes. (Some already existed, e.g., __doc__ and
5429 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005430
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005431- Add -3 option to the interpreter to warn about features that are
5432 deprecated and will be changed/removed in Python 3.0.
5433
Georg Brandl2134e752007-05-21 20:34:16 +00005434- Patch #1686487: you can now pass any mapping after '**' in function
5435 calls.
5436
Collin Winter62903052007-05-18 23:11:24 +00005437- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005438 "except E as target:". This is to provide forwards compatibility
5439 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005440
Brett Cannon229cee22007-05-05 01:34:02 +00005441- Deprecate BaseException.message as per PEP 352.
5442
Georg Brandl3ee81df2008-05-17 18:14:43 +00005443- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005444 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005445
Vinay Sajip8549ce32007-05-06 17:53:37 +00005446- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005447 setting a plain string, ie don't expand to single letter identifiers.
5448
Raymond Hettinger13936692007-04-11 18:40:58 +00005449- Request #1191699: Slices can now be pickled.
5450
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005451- Request #1193128: str.translate() now allows a None argument for
5452 translations that only remove characters without re-mapping the
5453 remaining characters.
5454
Georg Brandl5cb76c12007-03-21 09:00:39 +00005455- Patch #1682205: a TypeError while unpacking an iterable is no longer

5459
Guido van Rossum143b5642007-03-23 04:58:42 +00005460- Bug #1683368: The object.__init__() and object.__new__() methods are
5461 now stricter in rejecting excess arguments. The only time when
5462 either allows excess arguments is when it is not overridden and the
5463 other one is. For backwards compatibility, when both are
5464 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005465 warning later). Also, type.__init__() insists on the same signature
5466 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005467
Georg Brandl3ee81df2008-05-17 18:14:43 +00005468- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5469 object to complex using its __complex__() method before falling back
5470 to the __float__() method. Therefore, the functions in the cmath
5471 module now can operate on objects that define a __complex__()
5472 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005473
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Patch #1623563: allow __class__ assignment for classes with
5475 __slots__. The old and the new class are still required to have the
5476 same slot names.

5482 ``object.__reduce_ex__()`` is called with an object that is faking
5483 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005484
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- Patch #1680015: Don't modify __slots__ tuple if it contains an

5489
Georg Brandl7b9c5552007-03-12 14:30:05 +00005490- Bug #1678647: write a newline after printing an exception in any
5491 case, even when converting the value to a string failed.
5492
Georg Brandl871f1bc2007-03-12 13:17:36 +00005493- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494 its argument, if it exists. If not, it will work like before. This
5495 allows customizing the output of dir() in the presence of a
5496 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005497
Collin Winter276887b2007-03-12 16:11:39 +00005498- Patch #922167: Python no longer segfaults when faced with infinitely
5499 self-recursive reload() calls (as reported by bug #742342).
5500
Georg Brandl3ee81df2008-05-17 18:14:43 +00005501- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Patch #1491866: change the complex() constructor to allow
5505 parthensized forms. This means complex(repr(x)) now works instead of
5506 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005507
Georg Brandlaa2321b2007-03-07 00:40:28 +00005508- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509 makes the filenames the warning module prints much more sensible
5510 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005511

5513 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005514 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00005523- Patch #1674228: when assigning a slice (old-style), check for the
5524 sq_ass_slice instead of the sq_slice slot.
5525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- When printing an unraisable error, don't print exceptions. before
5527 the name. This duplicates the behavior whening normally printing
5528 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006079- Patch #1530482: add pydoc.render_doc() which returns the

6094
Georg Brandl92a6bae2007-03-13 17:43:32 +00006095- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006096 are set for invalid interpolation sequences that would lead to
6097 errors on reading back those values.

6153 TestCase and TestSuite subclasses (not instances) are no longer
6154 accepted in TestSuite.addTest(). This should cause no
6155 incompatibility since it never made sense with ordinary subclasses
6156 -- the failure just occurred later, with a more cumbersome
6157 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006444 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006545- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006546 time so that opening a database previously created with the DB_DUP
6547 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6548 opens. Specifically: dictionary assignment to a DB object will
6549 replace all values for a given key when the database allows
6550 duplicate values. DB users should use DB.put(k, v) when they want
6551 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006831 periodic threadstate and signal checking in tight loops. By
6832 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00006890
Georg Brandl3ee81df2008-05-17 18:14:43 +00006891- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6892 to ``PyTuple_SetItem``, it can be used to populate a brand new

6905
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6907 of w# format code incorrectly truncated the length to an int, even
6908 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6909 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006910

6933 outside of pystate.c and should not be necessary.
6934
Georg Brandl3ee81df2008-05-17 18:14:43 +00006935- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6936 absolute imports. In earlier versions they might have used relative
6937 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006938
Georg Brandl3ee81df2008-05-17 18:14:43 +00006939- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6940 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006941
Georg Brandl3ee81df2008-05-17 18:14:43 +00006942- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006967- Removed the macfs module. It had been deprecated since Python 2.5.
6968 This lead to the deprecation of macostools.touched() as it relied
6969 solely on macfs and was a no-op under OS X.
