Mark Dickinsona8d26682010-05-04 16:18:25 +000029- Issue #1533: fix inconsistency in range function argument
30 processing: any non-float non-integer argument is now converted to

32 small arguments were treated this way; larger arguments (those whose
33 __int__ was outside the range of a C long) would produce a TypeError.
34
Nick Coghlanc5e44852010-04-28 14:51:08 +000035- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when

69 error messages when accessing undefined class attributes because of the cheap
70 inheritance with the underlying socket object.
71 The cheap inheritance has been deprecated.
72
Tarek Ziadé38f81222010-05-05 22:15:31 +000073- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.

83
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000084- Issue #8567: Fix precedence of signals in Decimal module: when a
85 Decimal operation raises multiple signals and more than one of those
86 signals is trapped, the specification determines the order in which
87 the signals should be handled. In many cases this order wasn't

138
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000139- The do_handshake() method of SSL objects now adjusts the blocking mode of
140 the SSL structure if necessary (as other methods already do).
141

149
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000150- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
151 the string "python" as the *ident*. openlog() arguments are all optional
152 and keywords.
153
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000154- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
155 a non-infinite timeout. Also make that method friendlier with applications

185 filename and date, conforming to the 'standards' they were originally
186 designed to follow. This improves compatibility with patch tools.
187
R. David Murray27ef9372010-04-12 14:26:06 +0000188- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

265 is called with a non-empty format string. This is an effort to

267 implement __format__ but later adds its own __format__, it would
268 most likely break user code that had supplied a format string. This
269 will be changed to a DeprecationWaring in Python 3.3 and it will be

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000317- Issue #8294: The Fraction constructor now accepts Decimal and float
318 instances directly.
319
Mark Dickinsone096e822010-04-02 10:17:07 +0000320- Issue #7279: Comparisons involving a Decimal signaling NaN now
321 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000322 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
323 are now hashable; Decimal signaling NaNs remain unhashable.

Mark Dickinson99d80962010-04-02 08:53:22 +0000325- Issue #2531: Comparison operations between floats and Decimal
326 instances now return a result based on the numeric values of the
327 operands; previously they returned an arbitrary result based on
328 the relative ordering of id(float) and id(Decimal).
329
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000330- Issue #8233: When run as a script, py_compile.py optionally takes a single
331 argument `-` which tells it to read files to compile from stdin. Each line
332 is read on demand and the named file is compiled immediately. (Original
333 patch by Piotr Ożarowski).

Mark Dickinson9588d992010-03-27 11:14:37 +0000343- Comparisons using one of <, <=, >, >= between a complex instance and
344 a Fractions instance now raise TypeError instead of returning
345 True/False. This makes Fraction <=> complex comparisons consistent with
346 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000445- Issue #8300: When passing a non-integer argument to struct.pack with any
446 integer format code, struct.pack first attempts to convert the non-integer
447 using its __index__ method. If that method is non-existent or raises
448 TypeError it goes on to try the __int__ method, as described below.
449
Georg Brandlba83f822010-03-14 09:50:54 +0000450- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
451 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
452 argument's __int__ method to convert to an integer before packing. It also
453 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
454 was inconsistent: __int__ was used for some integer codes but not for others,
455 and the set of integer codes for which it was used differed between native
456 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000754 file position when calling `truncate()`. It would previously change the file
755 position to the given argument, which goes against the tradition of

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

852Core and Builtins
853-----------------
854
Georg Brandlba83f822010-03-14 09:50:54 +0000855- The ``__complex__()`` method is now looked up on the class of instances to
856 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000857
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000858- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
859 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
860
Mark Dickinson1b34d252010-01-01 17:27:30 +0000861- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000862 DeprecationWarning when passed a float argument where an integer was expected.
863 These functions and methods now raise TypeError instead. The majority of the
864 effects of this change are in the extension modules, but some core functions
865 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
866 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000874- Issue #7579: The msvcrt module now has docstrings for all its functions.
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000875
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000876- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
877 used to drop the time part of the result.
878
Georg Brandlba83f822010-03-14 09:50:54 +0000879- Issue #1811: Improve accuracy and cross-platform consistency for true division
880 of integers: the result of a/b is now correctly rounded for ints a and b (at
881 least on IEEE 754 platforms), and in particular does not depend on the
882 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000883
Georg Brandlba83f822010-03-14 09:50:54 +0000884- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
885 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
886 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000887
Georg Brandlba83f822010-03-14 09:50:54 +0000888- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000889 executables on OSX.
890
Georg Brandlba83f822010-03-14 09:50:54 +0000891 These executables now work properly with the arch(1) command: ``arch -ppc
892 python`` will start a universal binary version of python in PPC mode (unlike
893 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000894
Georg Brandlba83f822010-03-14 09:50:54 +0000895- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
896 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +0000907- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
908 allowing for a maximum number of tasks within the pool to be completed by the
909 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +0000916 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

953 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
954 the same as passing no argument.
955
Georg Brandlba83f822010-03-14 09:50:54 +0000956- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Mark Dickinsona36507c2010-01-30 10:08:33 +0000977
Georg Brandlba83f822010-03-14 09:50:54 +0000978- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
979 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
980 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
981 float arguments for integer format codes (other than 'L'): previously an

1033 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001034
Georg Brandlba83f822010-03-14 09:50:54 +00001035- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1036 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00001049- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1050 decimal string that's guaranteed to round back to x under correct rounding
1051 (with round-half-to-even rounding mode). Previously it gave a string based on
1052 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1053 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1054 not supported (see below), repr is unchanged.

1057 conversions within Python are now correctly rounded. Places these conversions
1058 occur include: str for floats and complex numbers; the float and complex
1059 constructors; old-style and new-style numeric formatting; serialization and
1060 deserialization of floats and complex numbers using marshal, pickle and json;
1061 parsing of float and imaginary literals in Python code; Decimal-to-float
1062 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001063
Georg Brandlba83f822010-03-14 09:50:54 +00001064 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1065 providing correctly-rounded strtod and dtoa C functions. This code is
1066 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1067 the C compiler. There may be a small number of platforms on which correct
1068 operation of this code cannot be guaranteed, so the code is not used: notably,
1069 this applies to platforms where the C double format is not IEEE 754 binary64,
1070 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1071 and Python's configure script is unable to determine how to change the FPU
1072 precision. On these platforms conversions use the platform strtod and dtoa,
1073 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001075- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1076 uses the correctly-rounded string <-> float conversions described above (when
1077 available), and so produces correctly rounded results that will display nicely
1078 under the float repr. There are two related small changes: (1) round now
1079 accepts any class with an ``__index__()`` method for its second argument (but
1080 no longer accepts floats for the second argument), and (2) an excessively
1081 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1082 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001300 untrackable objects are not tracked by the garbage collector. This can reduce
1301 the size of collections and therefore the garbage collection overhead on

1461 this code path is really executed because I cannot move to such directory on
1462 win2k)

1488 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002659 - Packing a float now always gives a Deprecation Warning. Previously it
2660 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00002662 - If x is not an int, long or float, then packing x will always result in
2663 struct.error. Previously an x with an __int__ method could be packed by
2664 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2665 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2666 neither __int__ nor __long__, TypeError used to be raised (with a
2667 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2668 struct.error in other cases.

2671 argument with an __int__ method can be packed, but use of this feature
2672 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002865- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2867 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2868 ``printf`` function, whereas PyString_FromFormat has an independent

2966 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2967 for catch_warnings() also led to an improvement in the raising of a
2968 DeprecationWarning related to warnings.warn_explicit().

2992
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002993- Issue #2975: When compiling several extension modules with Visual Studio 2008

2995 without limit.
2996
Benjamin Peterson37346b22008-08-23 20:27:43 +00002997- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003034What's New in Python 2.6 beta 3?
3035================================
3036
Barry Warsaw07a4a382008-08-21 01:15:08 +00003037*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003038
3039Core and Builtins
3040-----------------
3041
Guido van Rossumf8402962008-08-20 15:01:50 +00003042- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3043 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3044 extensions do not automatically benefit from the class attribute
3045 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3046 to their tp_flags field if they care. This is a backwards
3047 compatibility feature; in 3.0, all types will use the cache by
3048 default.
3049
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003050- Keyword arguments can now follow starred arguments. (``f(a, *args,
3051 keyword=23)`` is now valid syntax.)
3052
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003053- ctypes function pointers that are COM methods have a boolean True
3054 value again.
3055
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003056- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3057 by denying s# to parse objects that have a releasebuffer procedure,
3058 and introducing s*.
3059
Georg Brandl1e13ea92008-08-11 09:07:59 +00003060- Issue #3537: Fix an assertion failure when an empty but presized dict
3061 object was stored in the freelist.
3062
Mark Dickinsonb6467572008-08-04 21:30:09 +00003063- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3064 ValueError consistently across platforms.
3065
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003066- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3067 (64bit Unix, for example), unichr() would truncate its argument and return
3068 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3069
Neal Norwitze7d8be82008-07-31 17:17:14 +00003070- Apply security patches from Apple.
3071
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003072- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3073 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3074
Antoine Pitrou92f82162008-07-25 22:22:08 +00003075- Issue #1819: function calls with several named parameters are now on
3076 average 35% faster (as measured by pybench).
3077
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003078- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3079 the python debugger steps into a class statement: the free variables (local
3080 variables defined in an outer scope) would be deleted from the outer scope.
3081
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003082- Issue #2620: Overflow checking when allocating or reallocating memory
3083 was not always being done properly in some python types and extension
3084 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3085 all been updated to perform better checks and places in the code that
3086 would previously leak memory on the error path when such an allocation
3087 failed have been fixed.
3088

3090-------
3091

3093
Benjamin Petersone977ad42008-08-20 01:42:01 +00003094- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3095 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3096
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003097- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3098 version reported by these tools does not necessarily follow the python
3099 version numbering scheme, so the module is less strict when parsing it.
3100
Nick Coghlanf70385a2008-08-18 12:42:46 +00003101- Issue #2235: Added Py3k warnings for types which will become unhashable
3102 under the stricter __hash__ inheritance rules in 3.0. Several types
3103 which did not meet the rules for hash invariants and were already
3104 unhashable in 3.0 have now been explicitly flagged as unhashable in
3105 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3106 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3107
Brett Cannon88f801d2008-08-18 00:46:22 +00003108- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3116
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003117- Issue #3575: Incremental decoder's decode function now takes bytearray
3118 by using 's*' instead of 't#'.
3119
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003120- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003121 fails unicode conversion on 2nd parameter. (windows only)
3122
Facundo Batista94f243a2008-08-17 03:38:39 +00003123- Issue 2464. urllib2 now supports a malformation in the URL received
3124 in a redirect.
3125
Brett Cannonabe423e2008-08-16 21:47:07 +00003126- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003127 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003128
Facundo Batistaeb90b782008-08-16 14:44:07 +00003129- Issue #2776: fixed small issue when handling an URL with double slash
3130 after a 302 response in the case of not going through a proxy.
3131
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003132- Issue #2676: in the email package, content-type parsing was hanging on
3133 pathological input because of quadratic or exponential behaviour of a
3134 regular expression.
3135
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003136- Issue #3476: binary buffered reading through the new "io" library is now
3137 thread-safe.
3138
Brett Cannonbf3157b2008-08-14 05:00:03 +00003139- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3140 since mimetools itself is deprecated. Because modules are cached, all
3141 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3142
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003143- Issue #3134: shutil referenced undefined WindowsError symbol.
3144
Robert Schuppenies14646332008-08-10 11:01:53 +00003145- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3146 menu entries were not deleted.
3147
Brett Cannon83e81842008-08-09 23:30:55 +00003148- Copied the implementation of reduce() to _functools.reduce() to have a
3149 version that did not raise a DeprecationWarning under -3.
3150
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003151- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3152 a MemoryError rather than silently stop the iteration.
3153
Guido van Rossum59ce9012008-08-09 14:55:34 +00003154- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3155 to _sre.compile() will now be rejected. This should not affect anybody
3156 since the re.compile() function never generates invalid re-bytecode.
3157
Skip Montanaroa032bf42008-08-08 22:52:51 +00003158- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00003177 asking for a specific length. This problem only affected files opened
3178 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003179

3204 file name rather than a ZipInfo instance, so files are extracted with
3205 mode 0600 rather than 000 under Unix.
3206
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003207- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3224 regarding lack of coverage of new-style classes have also been
3225 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003228What's New in Python 2.6 beta 2?
3229================================
3230
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003231*Release date: 17-Jul-2008*
3232
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003233Core and Builtins
3234-----------------
3235
Georg Brandl3e483f62008-07-16 22:57:41 +00003236- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3237 its methods now allow for items objects that can be converted to
3238 an integer using operator.index().
3239
Mark Dickinson64b7e502008-07-16 09:40:03 +00003240- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3241 produced a ValueError instead of giving the correct float.
3242
Eric Smitha5fa5a22008-07-16 00:11:49 +00003243- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3244 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3245
Mark Dickinson7103aa42008-07-15 19:08:33 +00003246- Issue #3008: the float type has a new instance method 'float.hex'
3247 and a new class method 'float.fromhex' to convert floating-point
3248 numbers to and from hexadecimal strings, respectively.
3249
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003250- Issue #2235: __hash__ is once again inherited by default. To allow
3251 collections.Hashable to remain meaningful in the presence of the
3252 default hash implementation (object.__hash__), it is now possible
3253 to explicit block inheritance of hash by setting __hash__=None at
3254 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3255 level.
3256
Nick Coghlanb028f502008-07-13 14:52:36 +00003257- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3258 the parent module cannot be found while performing an absolute import.
3259 This means that an incorrectly defined __package__ attribute will
3260 now only prevent relative imports in that module rather than causing
3261 all imports from that module to fail.
3262
Nick Coghlan14ff9942008-07-08 14:21:42 +00003263- Issue #2517: Allow unicode messages in Exceptions again by correctly
3264 bypassing the instance dictionary when looking up __unicode__ on
3265 new-style classes.
3266
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003267- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3268 set to a custom object whose write() method happens to install
3269 another file in sys.stdout.
3270
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003271- Issue #3088: Corrected a race condition in classes derived from
3272 threading.local: the first member set by a thread could be saved in
3273 another thread's dictionary.
3274
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003275- Issue #3004: Minor change to slice.indices(): the start and stop
3276 arguments are now treated identically, making the behaviour easier
3277 to describe and understand. For example, slice(None, -10,
3278 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3279 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3280 10, -1).
3281
Georg Brandl278fc502008-07-19 12:46:12 +00003282- Issue #3219: Calling a function with repeated keyword arguments,
3283 f(a=2, a=23), would not cause a syntax error. This was a regression
3284 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003285
Georg Brandl278fc502008-07-19 12:46:12 +00003286- Issue #2862: Make int and float freelist management consistent with
3287 other freelists. Changes their CompactFreeList apis into
3288 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003289
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003290Library
3291-------
3292
Thomas Heller57adf222008-08-14 19:10:48 +00003293- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3294 api functions without holding the GIL, which could lead to a fatal
3295 error when they failed.
3296
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003297- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
3298
Jesse Noller7fb96402008-07-17 21:01:05 +00003299- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

3304
Jesse Noller13e9d582008-07-16 14:32:36 +00003305- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3306 ForkingPickler.register() to resolve conflict with ctypes.
3307
Vinay Sajip51e65192008-07-18 09:01:10 +00003308- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003309
Thomas Heller880f5292008-07-15 19:39:38 +00003310- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3311 a valid dlerror() message.
3312
Thomas Heller2bad6572008-07-15 17:19:50 +00003313- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3314 incomplete structure was created.
3315
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003316- Issue #3339: dummy_thread.acquire() should not return None.
3317
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003318- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3319
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003320- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003321
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003322- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3323 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003324 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003325 content-length. The problem had been corrected in the 2.4 branch, but never
3326 merged into trunk.
3327
Georg Brandle78fbcc2008-07-05 10:13:36 +00003328- Issue #2663: add filtering capability to shutil.copytree().
3329

3331
3332- Issue #1526: Allow more than 64k files to be added to Zip64 file.
3333
3334- Issue #1746: Correct handling of zipfile archive comments (previously
3335 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003336 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003337
Vinay Sajip51e65192008-07-18 09:01:10 +00003338- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003339 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003340
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003341- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3342 handling is now the same as that of other special attributes like __name__).
3343
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003344- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3345 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #1631171: Re-implement the 'warnings' module in C (the
3797 original Python code has been kept as backup). This will allow for
3798 using the 'warning's machinery in such places as the parser where
3799 use of pure Python code is not possible. Both the ``showarning()``
3800 and ``formatwarning()`` gain an optional 'line' argument which is
3801 not called by default for backwards-compatibility reasons. Setting
3802 ``warnings.showwarning()`` to an implementation that lacks support
3803 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Issue #2550: The approach used by client/server code for obtaining
3867 ports to listen on in network-oriented tests has been refined in an
3868 effort to facilitate running multiple instances of the entire
3869 regression test suite in parallel without issue.
3870 test_support.bind_port() has been fixed such that it will always
3871 return a unique port -- which wasn't always the case with the
3872 previous implementation, especially if socket options had been set
3873 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3874 new implementation of bind_port() will actually raise an exception
3875 if it is passed an AF_INET/SOCK_STREAM socket with either the
3876 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3877 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3878 the socket it's been passed. This currently only applies to
3879 Windows. This option prevents any other sockets from binding to the
3880 host/port we've bound to, thus removing the possibility of the
3881 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3882 when a second SOCK_STREAM socket binds and accepts to a host/port
3883 that's already been bound by another socket. The optional preferred
3884 port parameter to bind_port() has been removed. Under no
3885 circumstances should tests be hard coding ports!
3886
3887 test_support.find_unused_port() has also been introduced, which will
3888 pass a temporary socket object to bind_port() in order to obtain an
3889 unused port. The temporary socket object is then closed and
3890 deleted, and the port is returned. This method should only be used
3891 for obtaining an unused port in order to pass to an external program
3892 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3893 a parameter to a server-oriented class that doesn't give you direct
3894 access to the underlying socket used.
3895
3896 Finally, test_support.HOST has been introduced, which should be used
3897 for the host argument of any relevant socket calls (i.e. bind and
3898 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003899
3900 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003901 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3903 test_asynchat and test_socket_ssl.
3904
Georg Brandl3ee81df2008-05-17 18:14:43 +00003905 It is now possible for multiple instances of the regression test
3906 suite to run in parallel without issue.

4062 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00004063 platform.machine() and platform.processor() will report this
4064 information as well.

4173-----------------
4174
Fred Drakea8ee94b2008-03-01 02:45:07 +00004175- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004176 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004178- Issue #2067: file.__exit__() now calls subclasses' close() method.
4179
4180- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004181
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004182- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004183 issue 215555 for a discussion.
4184
Eric Smitha73fbe72008-02-23 03:09:44 +00004185- Added the future_builtins module, which contains hex() and oct().
4186 These are the PEP 3127 version of these functions, designed to be
4187 compatible with the hex() and oct() builtins from Python 3.0. They
4188 differ slightly in their output formats from the existing, unchanged
4189 Python 2.6 builtins. The expected usage of the future_builtins
4190 module is:
4191 from future_builtins import hex, oct
4192
Eric Smith7ef40bf2008-02-20 23:34:22 +00004193- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4194 exponents for exponents with absolute value < 100. Follows C99
4195 standard. This is a change on Windows, which would use 3 digits.
4196 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4197 so that any alterations it does to the resulting string will be
4198 available in stringlib/formatter.h (for float.__format__).
4199
Eric Smith5a3c1352008-02-19 13:21:56 +00004200- Implemented PEP 3101, Advanced String Formatting. This adds a new
4201 builtin format(); a format() method for str and unicode; a
4202 __format__() method to object, str, unicode, int, long, float, and
4203 datetime; the class string.Formatter; and the C API
4204 PyObject_Format().
4205
Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Fixed several potential crashes, all caused by specially crafted
4207 __del__ methods exploiting objects in temporarily inconsistent
4208 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004209
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004210- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211 prevent a possible crash: an Abstract Base Class would try to access
4212 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004213
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214- Fixed repr() and str() of complex numbers with infinity or nan as
4215 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Clear all free lists during a gc.collect() of the highest generation
4218 in order to allow pymalloc to free more arenas. Python may give back
4219 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Issue #2045: Fix an infinite recursion triggered when printing a
4222 subclass of collections.defaultdict, if its default_factory is set
4223 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004224
Christian Heimesf75dbef2008-02-08 00:11:31 +00004225- Fixed a minor memory leak in dictobject.c. The content of the free
4226 list was not freed on interpreter shutdown.
4227
Georg Brandl21e99f42010-03-07 15:23:59 +00004228- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004230
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4232 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004233 to compact the internal free lists of pre-allocted ints and floats.
4234
Georg Brandl3ee81df2008-05-17 18:14:43 +00004235- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4236 calls. Python expected the return type int but the fork familie
4237 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004238
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004248- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4249 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004250
Georg Brandl3ee81df2008-05-17 18:14:43 +00004251- Patch #1473257: generator objects gain a gi_code attribute. This is
4252 the same object as the func_code attribute of the function that
4253 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004254
Georg Brandl3ee81df2008-05-17 18:14:43 +00004255- Issue #1920: "while 0" statements were completely removed by the
4256 compiler, even in the presence of an "else" clause, which is
4257 supposed to be run when the condition is false. Now the compiler
4258 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004259
Guido van Rossumeead05f2008-01-24 18:21:02 +00004260- A few crashers fixed: weakref_in_del.py (issue #1377858);
4261 loosing_dict_ref.py (issue #1303614, test67.py);
4262 borrowed_ref_[34].py (not in tracker).
4263
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004264- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004265 suppressed while an extension is loaded by calling SetErrorMode in
4266 dynload_win.c. The error is still reported properly.
4267
Georg Brandl3ee81df2008-05-17 18:14:43 +00004268- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004269 several extension methods and modules do not work without unicode
4270 support.
4271
Georg Brandl26543b12008-01-21 18:36:51 +00004272- Issue #1882: when compiling code from a string, encoding cookies in the
4273 second line of code were not always recognized correctly.
4274
Georg Brandl14404b62008-01-19 19:27:05 +00004275- Issue #1679: "0x" was taken as a valid integer literal.
4276
Georg Brandl6caad7d2008-01-26 14:19:22 +00004277- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004278 added.
4279
Christian Heimesc94e2b52008-01-14 04:13:37 +00004280- sys.float_info / PyFloat_GetInfo: The floating point information
4281 object was converted from a dict to a specialized structseq object.
4282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Patch #1816: Added sys.flags structseq. It exposes the status of
4284 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004285
Georg Brandl3ee81df2008-05-17 18:14:43 +00004286- Objects/structseq.c: Implemented new structseq representation. The
4287 patch makes structseqs (e.g. the return value of os.stat) more
4288 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004289

Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4299 envvar and sys.dont_write_bytecode attribute. All these can be set
4300 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004301
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302- Improve some exception messages when Windows fails to load an
4303 extension module. Now we get for example '%1 is not a valid Win32
4304 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004305

Christian Heimes0a8143f2007-12-18 23:22:54 +00004311- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312 and INF. float("nan"), float("inf") and float("-inf") now work on
4313 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004314
Georg Brandl3ee81df2008-05-17 18:14:43 +00004315- Compiler now generates simpler and faster code for dictionary
4316 literals. The oparg for BUILD_MAP now indicates an estimated
4317 dictionary size. There is a new opcode, STORE_MAP, for adding
4318 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Patch #1739468: Directories and zipfiles containing a __main__.py
4348 file can now be directly executed by passing their name to the
4349 interpreter. The directory/zipfile is automatically inserted as the
4350 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004351
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Issue #1265: Fix a problem with sys.settrace, if the tracing
4353 function uses a generator expression when at the same time the
4354 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004355
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004356- sets and frozensets now have an isdisjoint() method.

4361
Georg Brandl21e99f42010-03-07 15:23:59 +00004362- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4364 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004365
Georg Brandl3ee81df2008-05-17 18:14:43 +00004366- Issue #1686386: Tuple's tp_repr did not take into account the
4367 possibility of having a self-referential tuple, which is possible
4368 from C code. Nor did object's tp_str consider that a type's tp_str
4369 could do something that could lead to an inifinite recursion.
4370 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4371 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004372
Georg Brandl3ee81df2008-05-17 18:14:43 +00004373- Issue #1164: It was possible to trigger deadlock when using the
4374 'print' statement to write to a file since the GIL was not released
4375 as needed. Now PyObject_Print() does the right thing along with
4376 various tp_print implementations of the built-in types and those in
4377 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004378
Georg Brandl3ee81df2008-05-17 18:14:43 +00004379- Issue #1147: Exceptions were directly allowing string exceptions in
4380 their throw() method even though string exceptions no longer
4381 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004382
Georg Brandl3ee81df2008-05-17 18:14:43 +00004383- Issue #1096: Prevent a segfault from getting the repr of a very
4384 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004385
Brett Cannon1e534b52007-09-07 04:18:30 +00004386- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004387 PyObject_Call() never calling back out to Python code to trigger
4388 recursion depth updates/checks. Required the creation of a static
4389 RuntimeError instance in case normalizing an exception put the
4390 recursion check value past its limit. Fixes crashers
4391 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004392
Georg Brandl3ee81df2008-05-17 18:14:43 +00004393- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004406- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004407 __*__ attributes. (Some already existed, e.g., __doc__ and
4408 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004409
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004410- Add -3 option to the interpreter to warn about features that are
4411 deprecated and will be changed/removed in Python 3.0.
4412
Georg Brandl2134e752007-05-21 20:34:16 +00004413- Patch #1686487: you can now pass any mapping after '**' in function
4414 calls.
4415
Collin Winter62903052007-05-18 23:11:24 +00004416- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004417 "except E as target:". This is to provide forwards compatibility
4418 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004419
Brett Cannon229cee22007-05-05 01:34:02 +00004420- Deprecate BaseException.message as per PEP 352.
4421
Georg Brandl3ee81df2008-05-17 18:14:43 +00004422- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004423 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004425- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004426 setting a plain string, ie don't expand to single letter identifiers.
4427
Raymond Hettinger13936692007-04-11 18:40:58 +00004428- Request #1191699: Slices can now be pickled.
4429
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004430- Request #1193128: str.translate() now allows a None argument for
4431 translations that only remove characters without re-mapping the
4432 remaining characters.
4433
Georg Brandl5cb76c12007-03-21 09:00:39 +00004434- Patch #1682205: a TypeError while unpacking an iterable is no longer
4435 masked by a generic one with the message "unpack non-sequence".
4436
Neal Norwitzaa754b72007-03-21 06:39:48 +00004437- Remove unused file Python/fmod.c.
4438
Guido van Rossum143b5642007-03-23 04:58:42 +00004439- Bug #1683368: The object.__init__() and object.__new__() methods are
4440 now stricter in rejecting excess arguments. The only time when
4441 either allows excess arguments is when it is not overridden and the
4442 other one is. For backwards compatibility, when both are
4443 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004444 warning later). Also, type.__init__() insists on the same signature
4445 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004446
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4448 object to complex using its __complex__() method before falling back
4449 to the __float__() method. Therefore, the functions in the cmath
4450 module now can operate on objects that define a __complex__()
4451 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004452
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453- Patch #1623563: allow __class__ assignment for classes with
4454 __slots__. The old and the new class are still required to have the
4455 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004456
Georg Brandl3ee81df2008-05-17 18:14:43 +00004457- Patch #1642547: Fix an error/crash when encountering syntax errors

4461 ``object.__reduce_ex__()`` is called with an object that is faking
4462 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004463
Georg Brandl3ee81df2008-05-17 18:14:43 +00004464- Patch #1680015: Don't modify __slots__ tuple if it contains an

4468
Georg Brandl7b9c5552007-03-12 14:30:05 +00004469- Bug #1678647: write a newline after printing an exception in any
4470 case, even when converting the value to a string failed.
4471
Georg Brandl871f1bc2007-03-12 13:17:36 +00004472- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004473 its argument, if it exists. If not, it will work like before. This
4474 allows customizing the output of dir() in the presence of a
4475 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004476
Collin Winter276887b2007-03-12 16:11:39 +00004477- Patch #922167: Python no longer segfaults when faced with infinitely
4478 self-recursive reload() calls (as reported by bug #742342).
4479
Georg Brandl3ee81df2008-05-17 18:14:43 +00004480- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Patch #1491866: change the complex() constructor to allow
4484 parthensized forms. This means complex(repr(x)) now works instead of
4485 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004486
Georg Brandlaa2321b2007-03-07 00:40:28 +00004487- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488 makes the filenames the warning module prints much more sensible
4489 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004490
Georg Brandl49aafc92007-03-07 00:34:46 +00004491- Variant of patch #697613: don't exit the interpreter on a SystemExit
4492 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004493 variable is given, but break into the interactive interpreter just
4494 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004502- Patch #1674228: when assigning a slice (old-style), check for the
4503 sq_ass_slice instead of the sq_slice slot.
4504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- When printing an unraisable error, don't print exceptions. before
4506 the name. This duplicates the behavior whening normally printing
4507 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005040 AttributeError instead of an IOError when the server's response
5041 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005042

Georg Brandl3ee81df2008-05-17 18:14:43 +00005058- Patch #1530482: add pydoc.render_doc() which returns the

5073
Georg Brandl92a6bae2007-03-13 17:43:32 +00005074- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005075 are set for invalid interpolation sequences that would lead to
5076 errors on reading back those values.

5132 TestCase and TestSuite subclasses (not instances) are no longer
5133 accepted in TestSuite.addTest(). This should cause no
5134 incompatibility since it never made sense with ordinary subclasses
5135 -- the failure just occurred later, with a more cumbersome
5136 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005525 time so that opening a database previously created with the DB_DUP
5526 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5527 opens. Specifically: dictionary assignment to a DB object will
5528 replace all values for a given key when the database allows
5529 duplicate values. DB users should use DB.put(k, v) when they want
5530 to store duplicates; not DB[k] = v.

5539 behavior of quoting dots if they are the second character of any
5540 line.

5886 of w# format code incorrectly truncated the length to an int, even
5887 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5888 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005918- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5919 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
