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

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

33
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000034- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

57 error messages when accessing undefined class attributes because of the cheap
58 inheritance with the underlying socket object.
59 The cheap inheritance has been deprecated.

71
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000072- Issue #8567: Fix precedence of signals in Decimal module: when a
73 Decimal operation raises multiple signals and more than one of those
74 signals is trapped, the specification determines the order in which
75 the signals should be handled. In many cases this order wasn't

Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000078- Issue #7865: The close() method of :mod:`io` objects should not swallow

106 Regebro.

122 witnessed in test_httpservers.
123
Antoine Pitroufc69af12010-04-24 20:04:58 +0000124- Issue #5103: SSL handshake would ignore the socket timeout and block

Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000127- The do_handshake() method of SSL objects now adjusts the blocking mode of
128 the SSL structure if necessary (as other methods already do).

140 and keywords.
141
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000142- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
143 a non-infinite timeout. Also make that method friendlier with applications
144 wanting to continue using the socket in clear-text mode, by disabling
145 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
146
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000147- Issue #8484: Load all ciphers and digest algorithms when initializing

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

256 is called with a non-empty format string. This is an effort to
257 future-proof user code. If a derived class does not currently
258 implement __format__ but later adds its own __format__, it would
259 most likely break user code that had supplied a format string. This
260 will be changed to a DeprecationWaring in Python 3.3 and it will be
261 an error in Python 3.4.

Mark Dickinsone096e822010-04-02 10:17:07 +0000311- Issue #7279: Comparisons involving a Decimal signaling NaN now
312 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000313 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
314 are now hashable; Decimal signaling NaNs remain unhashable.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000436- Issue #8300: When passing a non-integer argument to struct.pack with any
437 integer format code, struct.pack first attempts to convert the non-integer
438 using its __index__ method. If that method is non-existent or raises
439 TypeError it goes on to try the __int__ method, as described below.
440
Georg Brandlba83f822010-03-14 09:50:54 +0000441- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
442 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
443 argument's __int__ method to convert to an integer before packing. It also
444 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
445 was inconsistent: __int__ was used for some integer codes but not for others,
446 and the set of integer codes for which it was used differed between native
447 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000745 file position when calling `truncate()`. It would previously change the file
746 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000747 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

843Core and Builtins
844-----------------
845
Georg Brandlba83f822010-03-14 09:50:54 +0000846- The ``__complex__()`` method is now looked up on the class of instances to
847 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000848
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000849- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
850 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
851
Mark Dickinson1b34d252010-01-01 17:27:30 +0000852- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000853 DeprecationWarning when passed a float argument where an integer was expected.
854 These functions and methods now raise TypeError instead. The majority of the
855 effects of this change are in the extension modules, but some core functions
856 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
857 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000858

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000867- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
868 used to drop the time part of the result.
869
Georg Brandlba83f822010-03-14 09:50:54 +0000870- Issue #1811: Improve accuracy and cross-platform consistency for true division
871 of integers: the result of a/b is now correctly rounded for ints a and b (at
872 least on IEEE 754 platforms), and in particular does not depend on the
873 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000874
Georg Brandlba83f822010-03-14 09:50:54 +0000875- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
876 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
877 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000878
Georg Brandlba83f822010-03-14 09:50:54 +0000879- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000880 executables on OSX.
881
Georg Brandlba83f822010-03-14 09:50:54 +0000882 These executables now work properly with the arch(1) command: ``arch -ppc
883 python`` will start a universal binary version of python in PPC mode (unlike
884 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000885
Georg Brandlba83f822010-03-14 09:50:54 +0000886- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000898- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
899 allowing for a maximum number of tasks within the pool to be completed by the
900 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +0000907 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
908 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +0000909 Xicluna.

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000943- Issue #7349: Make methods of file objects in the io module accept None as an
944 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
945 the same as passing no argument.
946
Georg Brandlba83f822010-03-14 09:50:54 +0000947- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00001022- Issue #3382: 'F' formatting for float and complex now convert the result to
1023 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1024 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001025
Georg Brandlba83f822010-03-14 09:50:54 +00001026- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1027 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001028

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001039
Georg Brandlba83f822010-03-14 09:50:54 +00001040- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1041 decimal string that's guaranteed to round back to x under correct rounding
1042 (with round-half-to-even rounding mode). Previously it gave a string based on
1043 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1044 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1045 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001046
Georg Brandlba83f822010-03-14 09:50:54 +00001047- Issue #7117: On almost all platforms: float-to-string and string-to-float
1048 conversions within Python are now correctly rounded. Places these conversions
1049 occur include: str for floats and complex numbers; the float and complex
1050 constructors; old-style and new-style numeric formatting; serialization and
1051 deserialization of floats and complex numbers using marshal, pickle and json;
1052 parsing of float and imaginary literals in Python code; Decimal-to-float
1053 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001054
Georg Brandlba83f822010-03-14 09:50:54 +00001055 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1056 providing correctly-rounded strtod and dtoa C functions. This code is
1057 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1058 the C compiler. There may be a small number of platforms on which correct
1059 operation of this code cannot be guaranteed, so the code is not used: notably,
1060 this applies to platforms where the C double format is not IEEE 754 binary64,
1061 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1062 and Python's configure script is unable to determine how to change the FPU

Georg Brandlba83f822010-03-14 09:50:54 +00001066- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1067 uses the correctly-rounded string <-> float conversions described above (when
1068 available), and so produces correctly rounded results that will display nicely
1069 under the float repr. There are two related small changes: (1) round now
1070 accepts any class with an ``__index__()`` method for its second argument (but
1071 no longer accepts floats for the second argument), and (2) an excessively
1072 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1073 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001290- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001291 untrackable objects are not tracked by the garbage collector. This can reduce
1292 the size of collections and therefore the garbage collection overhead on
1293 long-running programs, depending on their particular use of datatypes.

1452 this code path is really executed because I cannot move to such directory on

1479 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002653 - If x is not an int, long or float, then packing x will always result in
2654 struct.error. Previously an x with an __int__ method could be packed by
2655 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2656 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2657 neither __int__ nor __long__, TypeError used to be raised (with a
2658 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2659 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00002661 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
2662 argument with an __int__ method can be packed, but use of this feature
2663 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002856- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2857 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2858 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2859 ``printf`` function, whereas PyString_FromFormat has an independent
2860 implementation and uses "%zd" on all platforms for size_t values.

2957 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2958 for catch_warnings() also led to an improvement in the raising of a
2959 DeprecationWarning related to warnings.warn_explicit().

2983
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002984- Issue #2975: When compiling several extension modules with Visual Studio 2008
2985 from the same python interpreter, some environment variables would grow
2986 without limit.
2987

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003025What's New in Python 2.6 beta 3?
3026================================
3027
Barry Warsaw07a4a382008-08-21 01:15:08 +00003028*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003029
3030Core and Builtins
3031-----------------
3032
Guido van Rossumf8402962008-08-20 15:01:50 +00003033- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3034 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3035 extensions do not automatically benefit from the class attribute
3036 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3037 to their tp_flags field if they care. This is a backwards
3038 compatibility feature; in 3.0, all types will use the cache by
3039 default.
3040
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003041- Keyword arguments can now follow starred arguments. (``f(a, *args,
3042 keyword=23)`` is now valid syntax.)
3043
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003044- ctypes function pointers that are COM methods have a boolean True
3045 value again.
3046
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003047- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3048 by denying s# to parse objects that have a releasebuffer procedure,
3049 and introducing s*.
3050
Georg Brandl1e13ea92008-08-11 09:07:59 +00003051- Issue #3537: Fix an assertion failure when an empty but presized dict
3052 object was stored in the freelist.
3053
Mark Dickinsonb6467572008-08-04 21:30:09 +00003054- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3055 ValueError consistently across platforms.
3056
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003057- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3058 (64bit Unix, for example), unichr() would truncate its argument and return
3059 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3060
Neal Norwitze7d8be82008-07-31 17:17:14 +00003061- Apply security patches from Apple.
3062
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003063- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3064 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3065
Antoine Pitrou92f82162008-07-25 22:22:08 +00003066- Issue #1819: function calls with several named parameters are now on
3067 average 35% faster (as measured by pybench).
3068
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003069- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3070 the python debugger steps into a class statement: the free variables (local
3071 variables defined in an outer scope) would be deleted from the outer scope.
3072
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003073- Issue #2620: Overflow checking when allocating or reallocating memory
3074 was not always being done properly in some python types and extension
3075 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3076 all been updated to perform better checks and places in the code that
3077 would previously leak memory on the error path when such an allocation
3078 failed have been fixed.

3084
Benjamin Petersone977ad42008-08-20 01:42:01 +00003085- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3086 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3087
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003088- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3089 version reported by these tools does not necessarily follow the python
3090 version numbering scheme, so the module is less strict when parsing it.
3091
Nick Coghlanf70385a2008-08-18 12:42:46 +00003092- Issue #2235: Added Py3k warnings for types which will become unhashable
3093 under the stricter __hash__ inheritance rules in 3.0. Several types
3094 which did not meet the rules for hash invariants and were already
3095 unhashable in 3.0 have now been explicitly flagged as unhashable in
3096 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3097 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3098
Brett Cannon88f801d2008-08-18 00:46:22 +00003099- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3107
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003108- Issue #3575: Incremental decoder's decode function now takes bytearray
3109 by using 's*' instead of 't#'.
3110
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003111- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003112 fails unicode conversion on 2nd parameter. (windows only)
3113
Facundo Batista94f243a2008-08-17 03:38:39 +00003114- Issue 2464. urllib2 now supports a malformation in the URL received
3115 in a redirect.
3116
Brett Cannonabe423e2008-08-16 21:47:07 +00003117- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +00003119
Facundo Batistaeb90b782008-08-16 14:44:07 +00003120- Issue #2776: fixed small issue when handling an URL with double slash
3121 after a 302 response in the case of not going through a proxy.
3122
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003123- Issue #2676: in the email package, content-type parsing was hanging on
3124 pathological input because of quadratic or exponential behaviour of a
3125 regular expression.
3126
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003127- Issue #3476: binary buffered reading through the new "io" library is now
3128 thread-safe.
3129
Brett Cannonbf3157b2008-08-14 05:00:03 +00003130- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3131 since mimetools itself is deprecated. Because modules are cached, all
3132 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3133
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003134- Issue #3134: shutil referenced undefined WindowsError symbol.
3135
Robert Schuppenies14646332008-08-10 11:01:53 +00003136- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3137 menu entries were not deleted.
3138
Brett Cannon83e81842008-08-09 23:30:55 +00003139- Copied the implementation of reduce() to _functools.reduce() to have a
3140 version that did not raise a DeprecationWarning under -3.
3141
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003142- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3143 a MemoryError rather than silently stop the iteration.
3144
Guido van Rossum59ce9012008-08-09 14:55:34 +00003145- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3146 to _sre.compile() will now be rejected. This should not affect anybody
3147 since the re.compile() function never generates invalid re-bytecode.
3148
Skip Montanaroa032bf42008-08-08 22:52:51 +00003149- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00003168 asking for a specific length. This problem only affected files opened
3169 using the new "io" module, not the built-in open() function.

3195 file name rather than a ZipInfo instance, so files are extracted with
3196 mode 0600 rather than 000 under Unix.
3197
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003198- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003219What's New in Python 2.6 beta 2?
3220================================
3221
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003222*Release date: 17-Jul-2008*
3223
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003224Core and Builtins
3225-----------------
3226
Georg Brandl3e483f62008-07-16 22:57:41 +00003227- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3228 its methods now allow for items objects that can be converted to
3229 an integer using operator.index().
3230
Mark Dickinson64b7e502008-07-16 09:40:03 +00003231- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3232 produced a ValueError instead of giving the correct float.
3233
Eric Smitha5fa5a22008-07-16 00:11:49 +00003234- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3235 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3236
Mark Dickinson7103aa42008-07-15 19:08:33 +00003237- Issue #3008: the float type has a new instance method 'float.hex'
3238 and a new class method 'float.fromhex' to convert floating-point
3239 numbers to and from hexadecimal strings, respectively.
3240
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003241- Issue #2235: __hash__ is once again inherited by default. To allow
3242 collections.Hashable to remain meaningful in the presence of the
3243 default hash implementation (object.__hash__), it is now possible
3244 to explicit block inheritance of hash by setting __hash__=None at
3245 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3246 level.
3247
Nick Coghlanb028f502008-07-13 14:52:36 +00003248- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3249 the parent module cannot be found while performing an absolute import.
3250 This means that an incorrectly defined __package__ attribute will
3251 now only prevent relative imports in that module rather than causing
3252 all imports from that module to fail.
3253
Nick Coghlan14ff9942008-07-08 14:21:42 +00003254- Issue #2517: Allow unicode messages in Exceptions again by correctly
3255 bypassing the instance dictionary when looking up __unicode__ on
3256 new-style classes.
3257
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003258- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3259 set to a custom object whose write() method happens to install
3260 another file in sys.stdout.
3261
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003262- Issue #3088: Corrected a race condition in classes derived from
3263 threading.local: the first member set by a thread could be saved in
3264 another thread's dictionary.
3265
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003266- Issue #3004: Minor change to slice.indices(): the start and stop
3267 arguments are now treated identically, making the behaviour easier
3268 to describe and understand. For example, slice(None, -10,
3269 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3270 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3271 10, -1).
3272
Georg Brandl278fc502008-07-19 12:46:12 +00003273- Issue #3219: Calling a function with repeated keyword arguments,
3274 f(a=2, a=23), would not cause a syntax error. This was a regression
3275 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003276
Georg Brandl278fc502008-07-19 12:46:12 +00003277- Issue #2862: Make int and float freelist management consistent with
3278 other freelists. Changes their CompactFreeList apis into
3279 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003280
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003281Library
3282-------
3283
Thomas Heller57adf222008-08-14 19:10:48 +00003284- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3285 api functions without holding the GIL, which could lead to a fatal
3286 error when they failed.
3287
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003288- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
3289

3295
Jesse Noller13e9d582008-07-16 14:32:36 +00003296- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3297 ForkingPickler.register() to resolve conflict with ctypes.
3298
Vinay Sajip51e65192008-07-18 09:01:10 +00003299- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003300
Thomas Heller880f5292008-07-15 19:39:38 +00003301- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3302 a valid dlerror() message.
3303
Thomas Heller2bad6572008-07-15 17:19:50 +00003304- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3305 incomplete structure was created.
3306
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003307- Issue #3339: dummy_thread.acquire() should not return None.
3308
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003309- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3310
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003311- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003312
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003313- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3314 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003315 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003316 content-length. The problem had been corrected in the 2.4 branch, but never
3317 merged into trunk.
3318
Georg Brandle78fbcc2008-07-05 10:13:36 +00003319- Issue #2663: add filtering capability to shutil.copytree().

3322
3323- Issue #1526: Allow more than 64k files to be added to Zip64 file.
3324
3325- Issue #1746: Correct handling of zipfile archive comments (previously
3326 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003327 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003328
Vinay Sajip51e65192008-07-18 09:01:10 +00003329- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003330 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003331
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003332- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3333 handling is now the same as that of other special attributes like __name__).
3334
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003335- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3336 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003787- Issue #1631171: Re-implement the 'warnings' module in C (the
3788 original Python code has been kept as backup). This will allow for
3789 using the 'warning's machinery in such places as the parser where
3790 use of pure Python code is not possible. Both the ``showarning()``
3791 and ``formatwarning()`` gain an optional 'line' argument which is
3792 not called by default for backwards-compatibility reasons. Setting
3793 ``warnings.showwarning()`` to an implementation that lacks support
3794 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Issue #2550: The approach used by client/server code for obtaining
3858 ports to listen on in network-oriented tests has been refined in an
3859 effort to facilitate running multiple instances of the entire
3860 regression test suite in parallel without issue.
3861 test_support.bind_port() has been fixed such that it will always
3862 return a unique port -- which wasn't always the case with the
3863 previous implementation, especially if socket options had been set
3864 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3865 new implementation of bind_port() will actually raise an exception
3866 if it is passed an AF_INET/SOCK_STREAM socket with either the
3867 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3868 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3869 the socket it's been passed. This currently only applies to
3870 Windows. This option prevents any other sockets from binding to the
3871 host/port we've bound to, thus removing the possibility of the
3872 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3873 when a second SOCK_STREAM socket binds and accepts to a host/port
3874 that's already been bound by another socket. The optional preferred
3875 port parameter to bind_port() has been removed. Under no
3876 circumstances should tests be hard coding ports!
3877
3878 test_support.find_unused_port() has also been introduced, which will
3879 pass a temporary socket object to bind_port() in order to obtain an
3880 unused port. The temporary socket object is then closed and
3881 deleted, and the port is returned. This method should only be used
3882 for obtaining an unused port in order to pass to an external program
3883 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3884 a parameter to a server-oriented class that doesn't give you direct
3885 access to the underlying socket used.
3886
3887 Finally, test_support.HOST has been introduced, which should be used
3888 for the host argument of any relevant socket calls (i.e. bind and
3889 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003890
3891 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003893 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3894 test_asynchat and test_socket_ssl.
3895
Georg Brandl3ee81df2008-05-17 18:14:43 +00003896 It is now possible for multiple instances of the regression test
3897 suite to run in parallel without issue.

4053 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00004054 platform.machine() and platform.processor() will report this
4055 information as well.

4164-----------------
4165
Fred Drakea8ee94b2008-03-01 02:45:07 +00004166- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004167 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004168
Georg Brandlad61bc82008-02-23 15:11:18 +00004169- Issue #2067: file.__exit__() now calls subclasses' close() method.
4170
4171- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004172
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004173- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004174 issue 215555 for a discussion.
4175
Eric Smitha73fbe72008-02-23 03:09:44 +00004176- Added the future_builtins module, which contains hex() and oct().
4177 These are the PEP 3127 version of these functions, designed to be
4178 compatible with the hex() and oct() builtins from Python 3.0. They
4179 differ slightly in their output formats from the existing, unchanged
4180 Python 2.6 builtins. The expected usage of the future_builtins
4181 module is:
4182 from future_builtins import hex, oct
4183
Eric Smith7ef40bf2008-02-20 23:34:22 +00004184- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4185 exponents for exponents with absolute value < 100. Follows C99
4186 standard. This is a change on Windows, which would use 3 digits.
4187 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4188 so that any alterations it does to the resulting string will be
4189 available in stringlib/formatter.h (for float.__format__).
4190
Eric Smith5a3c1352008-02-19 13:21:56 +00004191- Implemented PEP 3101, Advanced String Formatting. This adds a new
4192 builtin format(); a format() method for str and unicode; a
4193 __format__() method to object, str, unicode, int, long, float, and
4194 datetime; the class string.Formatter; and the C API
4195 PyObject_Format().
4196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Fixed several potential crashes, all caused by specially crafted
4198 __del__ methods exploiting objects in temporarily inconsistent
4199 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004200
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004201- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202 prevent a possible crash: an Abstract Base Class would try to access
4203 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004204

Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Clear all free lists during a gc.collect() of the highest generation
4209 in order to allow pymalloc to free more arenas. Python may give back
4210 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Issue #2045: Fix an infinite recursion triggered when printing a
4213 subclass of collections.defaultdict, if its default_factory is set
4214 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004215
Christian Heimesf75dbef2008-02-08 00:11:31 +00004216- Fixed a minor memory leak in dictobject.c. The content of the free
4217 list was not freed on interpreter shutdown.
4218
Georg Brandl21e99f42010-03-07 15:23:59 +00004219- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004221
Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4223 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004224 to compact the internal free lists of pre-allocted ints and floats.
4225
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4227 calls. Python expected the return type int but the fork familie
4228 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- Issue #1678380: Fix a bug that identifies 0j and -0j when they

4240 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Patch #1473257: generator objects gain a gi_code attribute. This is
4243 the same object as the func_code attribute of the function that
4244 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004245
Georg Brandl3ee81df2008-05-17 18:14:43 +00004246- Issue #1920: "while 0" statements were completely removed by the
4247 compiler, even in the presence of an "else" clause, which is
4248 supposed to be run when the condition is false. Now the compiler
4249 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004250
Guido van Rossumeead05f2008-01-24 18:21:02 +00004251- A few crashers fixed: weakref_in_del.py (issue #1377858);
4252 loosing_dict_ref.py (issue #1303614, test67.py);
4253 borrowed_ref_[34].py (not in tracker).
4254
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004255- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004256 suppressed while an extension is loaded by calling SetErrorMode in
4257 dynload_win.c. The error is still reported properly.
4258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004260 several extension methods and modules do not work without unicode
4261 support.
4262
Georg Brandl26543b12008-01-21 18:36:51 +00004263- Issue #1882: when compiling code from a string, encoding cookies in the
4264 second line of code were not always recognized correctly.
4265
Georg Brandl14404b62008-01-19 19:27:05 +00004266- Issue #1679: "0x" was taken as a valid integer literal.
4267
Georg Brandl6caad7d2008-01-26 14:19:22 +00004268- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004269 added.
4270
Christian Heimesc94e2b52008-01-14 04:13:37 +00004271- sys.float_info / PyFloat_GetInfo: The floating point information
4272 object was converted from a dict to a specialized structseq object.
4273
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Patch #1816: Added sys.flags structseq. It exposes the status of
4275 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004276
Georg Brandl3ee81df2008-05-17 18:14:43 +00004277- Objects/structseq.c: Implemented new structseq representation. The
4278 patch makes structseqs (e.g. the return value of os.stat) more
4279 readable.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004289- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4290 envvar and sys.dont_write_bytecode attribute. All these can be set
4291 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004292
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Improve some exception messages when Windows fails to load an
4294 extension module. Now we get for example '%1 is not a valid Win32
4295 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004302- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303 and INF. float("nan"), float("inf") and float("-inf") now work on
4304 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Compiler now generates simpler and faster code for dictionary
4307 literals. The oparg for BUILD_MAP now indicates an estimated
4308 dictionary size. There is a new opcode, STORE_MAP, for adding
4309 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004338- Patch #1739468: Directories and zipfiles containing a __main__.py
4339 file can now be directly executed by passing their name to the
4340 interpreter. The directory/zipfile is automatically inserted as the
4341 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Issue #1265: Fix a problem with sys.settrace, if the tracing
4344 function uses a generator expression when at the same time the
4345 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004346
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004347- sets and frozensets now have an isdisjoint() method.

4352
Georg Brandl21e99f42010-03-07 15:23:59 +00004353- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4355 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1686386: Tuple's tp_repr did not take into account the
4358 possibility of having a self-referential tuple, which is possible
4359 from C code. Nor did object's tp_str consider that a type's tp_str
4360 could do something that could lead to an inifinite recursion.
4361 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4362 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Issue #1164: It was possible to trigger deadlock when using the
4365 'print' statement to write to a file since the GIL was not released
4366 as needed. Now PyObject_Print() does the right thing along with
4367 various tp_print implementations of the built-in types and those in
4368 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004369
Georg Brandl3ee81df2008-05-17 18:14:43 +00004370- Issue #1147: Exceptions were directly allowing string exceptions in
4371 their throw() method even though string exceptions no longer
4372 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004374- Issue #1096: Prevent a segfault from getting the repr of a very
4375 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004376
Brett Cannon1e534b52007-09-07 04:18:30 +00004377- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004378 PyObject_Call() never calling back out to Python code to trigger
4379 recursion depth updates/checks. Required the creation of a static
4380 RuntimeError instance in case normalizing an exception put the
4381 recursion check value past its limit. Fixes crashers
4382 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004383

Neal Norwitz0ac60192007-05-27 04:08:54 +00004397- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398 __*__ attributes. (Some already existed, e.g., __doc__ and
4399 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004400
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004401- Add -3 option to the interpreter to warn about features that are
4402 deprecated and will be changed/removed in Python 3.0.
4403
Georg Brandl2134e752007-05-21 20:34:16 +00004404- Patch #1686487: you can now pass any mapping after '**' in function
4405 calls.
4406
Collin Winter62903052007-05-18 23:11:24 +00004407- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004408 "except E as target:". This is to provide forwards compatibility
4409 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004410
Brett Cannon229cee22007-05-05 01:34:02 +00004411- Deprecate BaseException.message as per PEP 352.
4412
Georg Brandl3ee81df2008-05-17 18:14:43 +00004413- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004414 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004416- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004417 setting a plain string, ie don't expand to single letter identifiers.
4418
Raymond Hettinger13936692007-04-11 18:40:58 +00004419- Request #1191699: Slices can now be pickled.
4420
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004421- Request #1193128: str.translate() now allows a None argument for
4422 translations that only remove characters without re-mapping the
4423 remaining characters.
4424
Georg Brandl5cb76c12007-03-21 09:00:39 +00004425- Patch #1682205: a TypeError while unpacking an iterable is no longer
4426 masked by a generic one with the message "unpack non-sequence".
4427

4429
Guido van Rossum143b5642007-03-23 04:58:42 +00004430- Bug #1683368: The object.__init__() and object.__new__() methods are
4431 now stricter in rejecting excess arguments. The only time when
4432 either allows excess arguments is when it is not overridden and the
4433 other one is. For backwards compatibility, when both are
4434 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004435 warning later). Also, type.__init__() insists on the same signature
4436 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004437
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4439 object to complex using its __complex__() method before falling back
4440 to the __float__() method. Therefore, the functions in the cmath
4441 module now can operate on objects that define a __complex__()
4442 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- Patch #1623563: allow __class__ assignment for classes with
4445 __slots__. The old and the new class are still required to have the
4446 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004447

4452 ``object.__reduce_ex__()`` is called with an object that is faking
4453 its type.

4459
Georg Brandl7b9c5552007-03-12 14:30:05 +00004460- Bug #1678647: write a newline after printing an exception in any
4461 case, even when converting the value to a string failed.
4462
Georg Brandl871f1bc2007-03-12 13:17:36 +00004463- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004464 its argument, if it exists. If not, it will work like before. This
4465 allows customizing the output of dir() in the presence of a
4466 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004468- Patch #922167: Python no longer segfaults when faced with infinitely
4469 self-recursive reload() calls (as reported by bug #742342).
4470
Georg Brandl3ee81df2008-05-17 18:14:43 +00004471- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004474- Patch #1491866: change the complex() constructor to allow
4475 parthensized forms. This means complex(repr(x)) now works instead of
4476 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004477
Georg Brandlaa2321b2007-03-07 00:40:28 +00004478- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479 makes the filenames the warning module prints much more sensible
4480 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004481

4483 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004484 variable is given, but break into the interactive interpreter just
4485 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004493- Patch #1674228: when assigning a slice (old-style), check for the
4494 sq_ass_slice instead of the sq_slice slot.
4495
Georg Brandl3ee81df2008-05-17 18:14:43 +00004496- When printing an unraisable error, don't print exceptions. before
4497 the name. This duplicates the behavior whening normally printing
4498 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004640- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00005031 AttributeError instead of an IOError when the server's response
5032 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005033

Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Patch #1530482: add pydoc.render_doc() which returns the

5064
Georg Brandl92a6bae2007-03-13 17:43:32 +00005065- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005066 are set for invalid interpolation sequences that would lead to
5067 errors on reading back those values.

5110 returned string up to the first NUL character.

5123 TestCase and TestSuite subclasses (not instances) are no longer
5124 accepted in TestSuite.addTest(). This should cause no
5125 incompatibility since it never made sense with ordinary subclasses
5126 -- the failure just occurred later, with a more cumbersome
5127 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005516 time so that opening a database previously created with the DB_DUP
5517 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5518 opens. Specifically: dictionary assignment to a DB object will
5519 replace all values for a given key when the database allows
5520 duplicate values. DB users should use DB.put(k, v) when they want
5521 to store duplicates; not DB[k] = v.

5530 behavior of quoting dots if they are the second character of any
5531 line.

5877 of w# format code incorrectly truncated the length to an int, even
5878 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5879 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005909- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5910 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
