16
Mark Dickinsona8d26682010-05-04 16:18:25 +000017- Issue #1533: fix inconsistency in range function argument
18 processing: any non-float non-integer argument is now converted to
19 an integer (if possible) using its __int__ method. Previously, only
20 small arguments were treated this way; larger arguments (those whose
21 __int__ was outside the range of a C long) would produce a TypeError.
22
Nick Coghlanc5e44852010-04-28 14:51:08 +000023- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when

30 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
31 benefit compared to the dynamic memory allocation fallback. Patch by
32 Charles-François Natali.
33
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000034- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

65
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000066- Issue #8567: Fix precedence of signals in Decimal module: when a
67 Decimal operation raises multiple signals and more than one of those
68 signals is trapped, the specification determines the order in which
69 the signals should be handled. In many cases this order wasn't
70 being followed, leading to the wrong Python exception being raised.
71
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000072- Issue #7865: The close() method of :mod:`io` objects should not swallow

98 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +000099 location of the raised exception. Based on initial patch by Lennart
100 Regebro.

114 where the method could block indefinitely if called just before the
115 event loop started running. This also fixes the occasional freezes
116 witnessed in test_httpservers.
117
Antoine Pitroufc69af12010-04-24 20:04:58 +0000118- Issue #5103: SSL handshake would ignore the socket timeout and block
119 indefinitely if the other end didn't respond.
120
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000121- The do_handshake() method of SSL objects now adjusts the blocking mode of

130 socket. Initial patch by Péter Szabó.
131
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000132- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
133 the string "python" as the *ident*. openlog() arguments are all optional
134 and keywords.
135
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000136- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
137 a non-infinite timeout. Also make that method friendlier with applications
138 wanting to continue using the socket in clear-text mode, by disabling
139 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
140
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000141- Issue #8484: Load all ciphers and digest algorithms when initializing

206 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

250 is called with a non-empty format string. This is an effort to
251 future-proof user code. If a derived class does not currently
252 implement __format__ but later adds its own __format__, it would
253 most likely break user code that had supplied a format string. This
254 will be changed to a DeprecationWaring in Python 3.3 and it will be
255 an error in Python 3.4.
256
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000257- Issue #8268: Old-style classes (not just instances) now support weak

Mark Dickinson99d80962010-04-02 08:53:22 +0000310- Issue #2531: Comparison operations between floats and Decimal
311 instances now return a result based on the numeric values of the
312 operands; previously they returned an arbitrary result based on
313 the relative ordering of id(float) and id(Decimal).

317 is read on demand and the named file is compiled immediately. (Original
318 patch by Piotr Ożarowski).

330 True/False. This makes Fraction <=> complex comparisons consistent with
331 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000430- Issue #8300: When passing a non-integer argument to struct.pack with any
431 integer format code, struct.pack first attempts to convert the non-integer
432 using its __index__ method. If that method is non-existent or raises
433 TypeError it goes on to try the __int__ method, as described below.
434
Georg Brandlba83f822010-03-14 09:50:54 +0000435- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
436 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
437 argument's __int__ method to convert to an integer before packing. It also
438 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
439 was inconsistent: __int__ was used for some integer codes but not for others,
440 and the set of integer codes for which it was used differed between native
441 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000738- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000739 file position when calling `truncate()`. It would previously change the file
740 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000741 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000760- Issue #7748: Since unicode values are supported for some metadata options in

762 encoded string for them. This ensures that the upload and register commands
763 send the correct values to PyPI without any error.

837Core and Builtins
838-----------------
839
Georg Brandlba83f822010-03-14 09:50:54 +0000840- The ``__complex__()`` method is now looked up on the class of instances to
841 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000842
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000843- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
844 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
845
Mark Dickinson1b34d252010-01-01 17:27:30 +0000846- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000847 DeprecationWarning when passed a float argument where an integer was expected.
848 These functions and methods now raise TypeError instead. The majority of the
849 effects of this change are in the extension modules, but some core functions
850 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
851 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000852

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000861- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
862 used to drop the time part of the result.
863
Georg Brandlba83f822010-03-14 09:50:54 +0000864- Issue #1811: Improve accuracy and cross-platform consistency for true division
865 of integers: the result of a/b is now correctly rounded for ints a and b (at
866 least on IEEE 754 platforms), and in particular does not depend on the
867 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000868
Georg Brandlba83f822010-03-14 09:50:54 +0000869- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
870 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
871 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000872
Georg Brandlba83f822010-03-14 09:50:54 +0000873- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000874 executables on OSX.
875
Georg Brandlba83f822010-03-14 09:50:54 +0000876 These executables now work properly with the arch(1) command: ``arch -ppc
877 python`` will start a universal binary version of python in PPC mode (unlike
878 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000879
Georg Brandlba83f822010-03-14 09:50:54 +0000880- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

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

Georg Brandlba83f822010-03-14 09:50:54 +0000901 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

938 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
939 the same as passing no argument.
940
Georg Brandlba83f822010-03-14 09:50:54 +0000941- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00001034- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1035 decimal string that's guaranteed to round back to x under correct rounding
1036 (with round-half-to-even rounding mode). Previously it gave a string based on
1037 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1038 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1039 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001040
Georg Brandlba83f822010-03-14 09:50:54 +00001041- Issue #7117: On almost all platforms: float-to-string and string-to-float
1042 conversions within Python are now correctly rounded. Places these conversions
1043 occur include: str for floats and complex numbers; the float and complex
1044 constructors; old-style and new-style numeric formatting; serialization and
1045 deserialization of floats and complex numbers using marshal, pickle and json;
1046 parsing of float and imaginary literals in Python code; Decimal-to-float
1047 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001048
Georg Brandlba83f822010-03-14 09:50:54 +00001049 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1050 providing correctly-rounded strtod and dtoa C functions. This code is
1051 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1052 the C compiler. There may be a small number of platforms on which correct
1053 operation of this code cannot be guaranteed, so the code is not used: notably,
1054 this applies to platforms where the C double format is not IEEE 754 binary64,
1055 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1056 and Python's configure script is unable to determine how to change the FPU

Georg Brandlba83f822010-03-14 09:50:54 +00001060- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1061 uses the correctly-rounded string <-> float conversions described above (when
1062 available), and so produces correctly rounded results that will display nicely
1063 under the float repr. There are two related small changes: (1) round now
1064 accepts any class with an ``__index__()`` method for its second argument (but
1065 no longer accepts floats for the second argument), and (2) an excessively
1066 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1067 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001284- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001285 untrackable objects are not tracked by the garbage collector. This can reduce
1286 the size of collections and therefore the garbage collection overhead on
1287 long-running programs, depending on their particular use of datatypes.

1446 this code path is really executed because I cannot move to such directory on

1473 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002647 - If x is not an int, long or float, then packing x will always result in
2648 struct.error. Previously an x with an __int__ method could be packed by
2649 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2650 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2651 neither __int__ nor __long__, TypeError used to be raised (with a
2652 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2653 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00002655 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
2656 argument with an __int__ method can be packed, but use of this feature
2657 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002850- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2851 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2852 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2853 ``printf`` function, whereas PyString_FromFormat has an independent
2854 implementation and uses "%zd" on all platforms for size_t values.
2855 This makes a difference on win64, where ``printf`` needs "%Id" to display
2856 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002876 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2877 mechanism. In the process, fix a bug where isinstance() and issubclass(),

2879 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2880 type object.

2951 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2952 for catch_warnings() also led to an improvement in the raising of a
2953 DeprecationWarning related to warnings.warn_explicit().
2954

2977
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002978- Issue #2975: When compiling several extension modules with Visual Studio 2008
2979 from the same python interpreter, some environment variables would grow
2980 without limit.
2981
Benjamin Peterson37346b22008-08-23 20:27:43 +00002982- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003019What's New in Python 2.6 beta 3?
3020================================
3021
Barry Warsaw07a4a382008-08-21 01:15:08 +00003022*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003023
3024Core and Builtins
3025-----------------
3026
Guido van Rossumf8402962008-08-20 15:01:50 +00003027- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3028 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3029 extensions do not automatically benefit from the class attribute
3030 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3031 to their tp_flags field if they care. This is a backwards
3032 compatibility feature; in 3.0, all types will use the cache by
3033 default.
3034
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003035- Keyword arguments can now follow starred arguments. (``f(a, *args,
3036 keyword=23)`` is now valid syntax.)
3037
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003038- ctypes function pointers that are COM methods have a boolean True
3039 value again.
3040
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003041- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3042 by denying s# to parse objects that have a releasebuffer procedure,
3043 and introducing s*.
3044
Georg Brandl1e13ea92008-08-11 09:07:59 +00003045- Issue #3537: Fix an assertion failure when an empty but presized dict
3046 object was stored in the freelist.
3047
Mark Dickinsonb6467572008-08-04 21:30:09 +00003048- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3049 ValueError consistently across platforms.
3050
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003051- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3052 (64bit Unix, for example), unichr() would truncate its argument and return
3053 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3054
Neal Norwitze7d8be82008-07-31 17:17:14 +00003055- Apply security patches from Apple.
3056
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003057- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3058 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3059
Antoine Pitrou92f82162008-07-25 22:22:08 +00003060- Issue #1819: function calls with several named parameters are now on
3061 average 35% faster (as measured by pybench).
3062
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003063- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3064 the python debugger steps into a class statement: the free variables (local
3065 variables defined in an outer scope) would be deleted from the outer scope.
3066
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003067- Issue #2620: Overflow checking when allocating or reallocating memory
3068 was not always being done properly in some python types and extension
3069 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3070 all been updated to perform better checks and places in the code that
3071 would previously leak memory on the error path when such an allocation
3072 failed have been fixed.

3075-------
3076
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003077- Issue #3612: Added some missing basic types in ctypes.wintypes.
3078
Benjamin Petersone977ad42008-08-20 01:42:01 +00003079- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3080 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3081
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003082- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3083 version reported by these tools does not necessarily follow the python
3084 version numbering scheme, so the module is less strict when parsing it.
3085
Nick Coghlanf70385a2008-08-18 12:42:46 +00003086- Issue #2235: Added Py3k warnings for types which will become unhashable
3087 under the stricter __hash__ inheritance rules in 3.0. Several types
3088 which did not meet the rules for hash invariants and were already
3089 unhashable in 3.0 have now been explicitly flagged as unhashable in
3090 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3091 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3092
Brett Cannon88f801d2008-08-18 00:46:22 +00003093- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3101
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003102- Issue #3575: Incremental decoder's decode function now takes bytearray
3103 by using 's*' instead of 't#'.
3104
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003105- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003106 fails unicode conversion on 2nd parameter. (windows only)
3107
Facundo Batista94f243a2008-08-17 03:38:39 +00003108- Issue 2464. urllib2 now supports a malformation in the URL received
3109 in a redirect.
3110
Brett Cannonabe423e2008-08-16 21:47:07 +00003111- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003112 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003113
Facundo Batistaeb90b782008-08-16 14:44:07 +00003114- Issue #2776: fixed small issue when handling an URL with double slash
3115 after a 302 response in the case of not going through a proxy.
3116
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003117- Issue #2676: in the email package, content-type parsing was hanging on
3118 pathological input because of quadratic or exponential behaviour of a
3119 regular expression.
3120
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003121- Issue #3476: binary buffered reading through the new "io" library is now
3122 thread-safe.
3123
Brett Cannonbf3157b2008-08-14 05:00:03 +00003124- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3125 since mimetools itself is deprecated. Because modules are cached, all
3126 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3127
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003128- Issue #3134: shutil referenced undefined WindowsError symbol.
3129
Robert Schuppenies14646332008-08-10 11:01:53 +00003130- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3131 menu entries were not deleted.
3132
Brett Cannon83e81842008-08-09 23:30:55 +00003133- Copied the implementation of reduce() to _functools.reduce() to have a
3134 version that did not raise a DeprecationWarning under -3.
3135
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003136- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3137 a MemoryError rather than silently stop the iteration.
3138
Guido van Rossum59ce9012008-08-09 14:55:34 +00003139- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3140 to _sre.compile() will now be rejected. This should not affect anybody
3141 since the re.compile() function never generates invalid re-bytecode.
3142
Skip Montanaroa032bf42008-08-08 22:52:51 +00003143- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00003147- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3148 the reload() built-in has been removed.
3149
Brett Cannon7e30b672008-08-04 21:52:25 +00003150- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00003162 asking for a specific length. This problem only affected files opened
3163 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003164

3189 file name rather than a ZipInfo instance, so files are extracted with
3190 mode 0600 rather than 000 under Unix.
3191
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003192- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003213What's New in Python 2.6 beta 2?
3214================================
3215
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003216*Release date: 17-Jul-2008*
3217
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003218Core and Builtins
3219-----------------
3220
Georg Brandl3e483f62008-07-16 22:57:41 +00003221- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3222 its methods now allow for items objects that can be converted to
3223 an integer using operator.index().
3224
Mark Dickinson64b7e502008-07-16 09:40:03 +00003225- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3226 produced a ValueError instead of giving the correct float.
3227
Eric Smitha5fa5a22008-07-16 00:11:49 +00003228- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3229 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3230
Mark Dickinson7103aa42008-07-15 19:08:33 +00003231- Issue #3008: the float type has a new instance method 'float.hex'
3232 and a new class method 'float.fromhex' to convert floating-point
3233 numbers to and from hexadecimal strings, respectively.
3234
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003235- Issue #2235: __hash__ is once again inherited by default. To allow
3236 collections.Hashable to remain meaningful in the presence of the
3237 default hash implementation (object.__hash__), it is now possible
3238 to explicit block inheritance of hash by setting __hash__=None at
3239 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3240 level.
3241
Nick Coghlanb028f502008-07-13 14:52:36 +00003242- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3243 the parent module cannot be found while performing an absolute import.
3244 This means that an incorrectly defined __package__ attribute will
3245 now only prevent relative imports in that module rather than causing
3246 all imports from that module to fail.
3247
Nick Coghlan14ff9942008-07-08 14:21:42 +00003248- Issue #2517: Allow unicode messages in Exceptions again by correctly
3249 bypassing the instance dictionary when looking up __unicode__ on
3250 new-style classes.
3251
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003252- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3253 set to a custom object whose write() method happens to install
3254 another file in sys.stdout.
3255
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003256- Issue #3088: Corrected a race condition in classes derived from
3257 threading.local: the first member set by a thread could be saved in
3258 another thread's dictionary.
3259
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003260- Issue #3004: Minor change to slice.indices(): the start and stop
3261 arguments are now treated identically, making the behaviour easier
3262 to describe and understand. For example, slice(None, -10,
3263 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3264 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3265 10, -1).
3266
Georg Brandl278fc502008-07-19 12:46:12 +00003267- Issue #3219: Calling a function with repeated keyword arguments,
3268 f(a=2, a=23), would not cause a syntax error. This was a regression
3269 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003270
Georg Brandl278fc502008-07-19 12:46:12 +00003271- Issue #2862: Make int and float freelist management consistent with
3272 other freelists. Changes their CompactFreeList apis into
3273 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003274
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003275Library
3276-------
3277
Thomas Heller57adf222008-08-14 19:10:48 +00003278- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3279 api functions without holding the GIL, which could lead to a fatal
3280 error when they failed.
3281
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003282- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
3283
Jesse Noller7fb96402008-07-17 21:01:05 +00003284- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

3289
Jesse Noller13e9d582008-07-16 14:32:36 +00003290- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3291 ForkingPickler.register() to resolve conflict with ctypes.
3292
Vinay Sajip51e65192008-07-18 09:01:10 +00003293- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003294
Thomas Heller880f5292008-07-15 19:39:38 +00003295- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3296 a valid dlerror() message.
3297
Thomas Heller2bad6572008-07-15 17:19:50 +00003298- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3299 incomplete structure was created.
3300
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003301- Issue #3339: dummy_thread.acquire() should not return None.
3302
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003303- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3304
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003305- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003306
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003307- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3308 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003309 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003310 content-length. The problem had been corrected in the 2.4 branch, but never
3311 merged into trunk.
3312
Georg Brandle78fbcc2008-07-05 10:13:36 +00003313- Issue #2663: add filtering capability to shutil.copytree().

3316
3317- Issue #1526: Allow more than 64k files to be added to Zip64 file.
3318
3319- Issue #1746: Correct handling of zipfile archive comments (previously
3320 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003321 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003322
Vinay Sajip51e65192008-07-18 09:01:10 +00003323- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003324 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003325
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003326- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3327 handling is now the same as that of other special attributes like __name__).
3328
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003329- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3330 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003781- Issue #1631171: Re-implement the 'warnings' module in C (the
3782 original Python code has been kept as backup). This will allow for
3783 using the 'warning's machinery in such places as the parser where
3784 use of pure Python code is not possible. Both the ``showarning()``
3785 and ``formatwarning()`` gain an optional 'line' argument which is
3786 not called by default for backwards-compatibility reasons. Setting
3787 ``warnings.showwarning()`` to an implementation that lacks support
3788 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Issue #2550: The approach used by client/server code for obtaining
3852 ports to listen on in network-oriented tests has been refined in an
3853 effort to facilitate running multiple instances of the entire
3854 regression test suite in parallel without issue.
3855 test_support.bind_port() has been fixed such that it will always
3856 return a unique port -- which wasn't always the case with the
3857 previous implementation, especially if socket options had been set
3858 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3859 new implementation of bind_port() will actually raise an exception
3860 if it is passed an AF_INET/SOCK_STREAM socket with either the
3861 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3862 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3863 the socket it's been passed. This currently only applies to
3864 Windows. This option prevents any other sockets from binding to the
3865 host/port we've bound to, thus removing the possibility of the
3866 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3867 when a second SOCK_STREAM socket binds and accepts to a host/port
3868 that's already been bound by another socket. The optional preferred
3869 port parameter to bind_port() has been removed. Under no
3870 circumstances should tests be hard coding ports!
3871
3872 test_support.find_unused_port() has also been introduced, which will
3873 pass a temporary socket object to bind_port() in order to obtain an
3874 unused port. The temporary socket object is then closed and
3875 deleted, and the port is returned. This method should only be used
3876 for obtaining an unused port in order to pass to an external program
3877 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3878 a parameter to a server-oriented class that doesn't give you direct
3879 access to the underlying socket used.
3880
3881 Finally, test_support.HOST has been introduced, which should be used
3882 for the host argument of any relevant socket calls (i.e. bind and
3883 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003884
3885 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003887 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3888 test_asynchat and test_socket_ssl.
3889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890 It is now possible for multiple instances of the regression test
3891 suite to run in parallel without issue.

4047 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00004048 platform.machine() and platform.processor() will report this
4049 information as well.

4158-----------------
4159
Fred Drakea8ee94b2008-03-01 02:45:07 +00004160- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004161 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004162
Georg Brandlad61bc82008-02-23 15:11:18 +00004163- Issue #2067: file.__exit__() now calls subclasses' close() method.
4164
4165- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004166
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004167- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004168 issue 215555 for a discussion.
4169
Eric Smitha73fbe72008-02-23 03:09:44 +00004170- Added the future_builtins module, which contains hex() and oct().
4171 These are the PEP 3127 version of these functions, designed to be
4172 compatible with the hex() and oct() builtins from Python 3.0. They
4173 differ slightly in their output formats from the existing, unchanged
4174 Python 2.6 builtins. The expected usage of the future_builtins
4175 module is:
4176 from future_builtins import hex, oct
4177
Eric Smith7ef40bf2008-02-20 23:34:22 +00004178- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4179 exponents for exponents with absolute value < 100. Follows C99
4180 standard. This is a change on Windows, which would use 3 digits.
4181 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4182 so that any alterations it does to the resulting string will be
4183 available in stringlib/formatter.h (for float.__format__).
4184
Eric Smith5a3c1352008-02-19 13:21:56 +00004185- Implemented PEP 3101, Advanced String Formatting. This adds a new
4186 builtin format(); a format() method for str and unicode; a
4187 __format__() method to object, str, unicode, int, long, float, and
4188 datetime; the class string.Formatter; and the C API
4189 PyObject_Format().
4190
Georg Brandl3ee81df2008-05-17 18:14:43 +00004191- Fixed several potential crashes, all caused by specially crafted
4192 __del__ methods exploiting objects in temporarily inconsistent
4193 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004194
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004195- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196 prevent a possible crash: an Abstract Base Class would try to access
4197 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004198
Georg Brandl3ee81df2008-05-17 18:14:43 +00004199- Fixed repr() and str() of complex numbers with infinity or nan as
4200 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004202- Clear all free lists during a gc.collect() of the highest generation
4203 in order to allow pymalloc to free more arenas. Python may give back
4204 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004205
Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Issue #2045: Fix an infinite recursion triggered when printing a
4207 subclass of collections.defaultdict, if its default_factory is set
4208 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004209
Christian Heimesf75dbef2008-02-08 00:11:31 +00004210- Fixed a minor memory leak in dictobject.c. The content of the free
4211 list was not freed on interpreter shutdown.
4212
Georg Brandl21e99f42010-03-07 15:23:59 +00004213- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004215
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4217 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004218 to compact the internal free lists of pre-allocted ints and floats.
4219
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4221 calls. Python expected the return type int but the fork familie
4222 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4234 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Patch #1473257: generator objects gain a gi_code attribute. This is
4237 the same object as the func_code attribute of the function that
4238 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Issue #1920: "while 0" statements were completely removed by the
4241 compiler, even in the presence of an "else" clause, which is
4242 supposed to be run when the condition is false. Now the compiler
4243 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004244
Guido van Rossumeead05f2008-01-24 18:21:02 +00004245- A few crashers fixed: weakref_in_del.py (issue #1377858);
4246 loosing_dict_ref.py (issue #1303614, test67.py);
4247 borrowed_ref_[34].py (not in tracker).
4248
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004249- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004250 suppressed while an extension is loaded by calling SetErrorMode in
4251 dynload_win.c. The error is still reported properly.
4252
Georg Brandl3ee81df2008-05-17 18:14:43 +00004253- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004254 several extension methods and modules do not work without unicode
4255 support.
4256
Georg Brandl26543b12008-01-21 18:36:51 +00004257- Issue #1882: when compiling code from a string, encoding cookies in the
4258 second line of code were not always recognized correctly.
4259
Georg Brandl14404b62008-01-19 19:27:05 +00004260- Issue #1679: "0x" was taken as a valid integer literal.
4261
Georg Brandl6caad7d2008-01-26 14:19:22 +00004262- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004263 added.
4264
Christian Heimesc94e2b52008-01-14 04:13:37 +00004265- sys.float_info / PyFloat_GetInfo: The floating point information
4266 object was converted from a dict to a specialized structseq object.
4267
Georg Brandl3ee81df2008-05-17 18:14:43 +00004268- Patch #1816: Added sys.flags structseq. It exposes the status of
4269 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004270
Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Objects/structseq.c: Implemented new structseq representation. The
4272 patch makes structseqs (e.g. the return value of os.stat) more
4273 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004274

Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4284 envvar and sys.dont_write_bytecode attribute. All these can be set
4285 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004286
Georg Brandl3ee81df2008-05-17 18:14:43 +00004287- Improve some exception messages when Windows fails to load an
4288 extension module. Now we get for example '%1 is not a valid Win32
4289 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004296- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004297 and INF. float("nan"), float("inf") and float("-inf") now work on
4298 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Compiler now generates simpler and faster code for dictionary
4301 literals. The oparg for BUILD_MAP now indicates an estimated
4302 dictionary size. There is a new opcode, STORE_MAP, for adding
4303 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004332- Patch #1739468: Directories and zipfiles containing a __main__.py
4333 file can now be directly executed by passing their name to the
4334 interpreter. The directory/zipfile is automatically inserted as the
4335 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Issue #1265: Fix a problem with sys.settrace, if the tracing
4338 function uses a generator expression when at the same time the
4339 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004340
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004341- sets and frozensets now have an isdisjoint() method.

4346
Georg Brandl21e99f42010-03-07 15:23:59 +00004347- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4349 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004350
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Issue #1686386: Tuple's tp_repr did not take into account the
4352 possibility of having a self-referential tuple, which is possible
4353 from C code. Nor did object's tp_str consider that a type's tp_str
4354 could do something that could lead to an inifinite recursion.
4355 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4356 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004357
Georg Brandl3ee81df2008-05-17 18:14:43 +00004358- Issue #1164: It was possible to trigger deadlock when using the
4359 'print' statement to write to a file since the GIL was not released
4360 as needed. Now PyObject_Print() does the right thing along with
4361 various tp_print implementations of the built-in types and those in
4362 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Issue #1147: Exceptions were directly allowing string exceptions in
4365 their throw() method even though string exceptions no longer
4366 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004368- Issue #1096: Prevent a segfault from getting the repr of a very
4369 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004370
Brett Cannon1e534b52007-09-07 04:18:30 +00004371- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004372 PyObject_Call() never calling back out to Python code to trigger
4373 recursion depth updates/checks. Required the creation of a static
4374 RuntimeError instance in case normalizing an exception put the
4375 recursion check value past its limit. Fixes crashers
4376 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004377

Neal Norwitz0ac60192007-05-27 04:08:54 +00004391- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392 __*__ attributes. (Some already existed, e.g., __doc__ and
4393 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004394
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004395- Add -3 option to the interpreter to warn about features that are
4396 deprecated and will be changed/removed in Python 3.0.
4397
Georg Brandl2134e752007-05-21 20:34:16 +00004398- Patch #1686487: you can now pass any mapping after '**' in function
4399 calls.
4400
Collin Winter62903052007-05-18 23:11:24 +00004401- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004402 "except E as target:". This is to provide forwards compatibility
4403 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004405- Deprecate BaseException.message as per PEP 352.
4406
Georg Brandl3ee81df2008-05-17 18:14:43 +00004407- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004408 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004410- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004411 setting a plain string, ie don't expand to single letter identifiers.
4412
Raymond Hettinger13936692007-04-11 18:40:58 +00004413- Request #1191699: Slices can now be pickled.
4414
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004415- Request #1193128: str.translate() now allows a None argument for
4416 translations that only remove characters without re-mapping the
4417 remaining characters.
4418
Georg Brandl5cb76c12007-03-21 09:00:39 +00004419- Patch #1682205: a TypeError while unpacking an iterable is no longer
4420 masked by a generic one with the message "unpack non-sequence".
4421

4423
Guido van Rossum143b5642007-03-23 04:58:42 +00004424- Bug #1683368: The object.__init__() and object.__new__() methods are
4425 now stricter in rejecting excess arguments. The only time when
4426 either allows excess arguments is when it is not overridden and the
4427 other one is. For backwards compatibility, when both are
4428 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004429 warning later). Also, type.__init__() insists on the same signature
4430 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004431
Georg Brandl3ee81df2008-05-17 18:14:43 +00004432- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4433 object to complex using its __complex__() method before falling back
4434 to the __float__() method. Therefore, the functions in the cmath
4435 module now can operate on objects that define a __complex__()
4436 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004437
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438- Patch #1623563: allow __class__ assignment for classes with
4439 __slots__. The old and the new class are still required to have the
4440 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004441

4446 ``object.__reduce_ex__()`` is called with an object that is faking
4447 its type.

4453
Georg Brandl7b9c5552007-03-12 14:30:05 +00004454- Bug #1678647: write a newline after printing an exception in any
4455 case, even when converting the value to a string failed.
4456
Georg Brandl871f1bc2007-03-12 13:17:36 +00004457- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004458 its argument, if it exists. If not, it will work like before. This
4459 allows customizing the output of dir() in the presence of a
4460 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004462- Patch #922167: Python no longer segfaults when faced with infinitely
4463 self-recursive reload() calls (as reported by bug #742342).
4464
Georg Brandl3ee81df2008-05-17 18:14:43 +00004465- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- Patch #1491866: change the complex() constructor to allow
4469 parthensized forms. This means complex(repr(x)) now works instead of
4470 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004471
Georg Brandlaa2321b2007-03-07 00:40:28 +00004472- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004473 makes the filenames the warning module prints much more sensible
4474 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004475

4477 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478 variable is given, but break into the interactive interpreter just
4479 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004487- Patch #1674228: when assigning a slice (old-style), check for the
4488 sq_ass_slice instead of the sq_slice slot.
4489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- When printing an unraisable error, don't print exceptions. before
4491 the name. This duplicates the behavior whening normally printing
4492 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004634- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00005025 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00005027

Georg Brandl3ee81df2008-05-17 18:14:43 +00005043- Patch #1530482: add pydoc.render_doc() which returns the

5058
Georg Brandl92a6bae2007-03-13 17:43:32 +00005059- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005060 are set for invalid interpolation sequences that would lead to
5061 errors on reading back those values.

5117 TestCase and TestSuite subclasses (not instances) are no longer
5118 accepted in TestSuite.addTest(). This should cause no
5119 incompatibility since it never made sense with ordinary subclasses
5120 -- the failure just occurred later, with a more cumbersome
5121 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005510 time so that opening a database previously created with the DB_DUP
5511 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5512 opens. Specifically: dictionary assignment to a DB object will
5513 replace all values for a given key when the database allows
5514 duplicate values. DB users should use DB.put(k, v) when they want
5515 to store duplicates; not DB[k] = v.

5524 behavior of quoting dots if they are the second character of any
5525 line.

5871 of w# format code incorrectly truncated the length to an int, even
5872 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5873 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005903- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5904 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
