16
Mark Dickinsona8d26682010-05-04 16:18:25 +000017- Issue #1533: fix inconsistency in range function argument
18 processing: any non-float non-integer argument is now converted to
19 an integer (if possible) using its __int__ method. Previously, only
20 small arguments were treated this way; larger arguments (those whose
21 __int__ was outside the range of a C long) would produce a TypeError.

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

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

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

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

125
Antoine Pitroub558f172010-04-23 23:25:45 +0000126- Issue #5238: Calling makefile() on an SSL object would prevent the
127 underlying socket from being closed until all objects get truely destroyed.
128
Antoine Pitroudfb299b2010-04-23 22:54:59 +0000129- Issue #7943: Fix circular reference created when instantiating an SSL
130 socket. Initial patch by Péter Szabó.
131
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000132- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
133 the string "python" as the *ident*. openlog() arguments are all optional
134 and keywords.
135
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000136- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
137 a non-infinite timeout. Also make that method friendlier with applications

167 filename and date, conforming to the 'standards' they were originally
168 designed to follow. This improves compatibility with patch tools.
169
R. David Murray27ef9372010-04-12 14:26:06 +0000170- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

230
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000231- Issue #8329: Don't return the same lists from select.select when no fds are
232 changed.
233
Mark Dickinson82791672010-04-06 16:47:55 +0000234- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
235 on 64-bit machines. The shift count for either left or right shift is

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

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000277- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
278 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
279 and `ssl.OPENSSL_VERSION_NUMBER`.
280

Raymond Hettingera551f312010-04-04 18:34:45 +0000291- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000292 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000293
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000294- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000295 old-style comparison functions to new-style key-functions.

301 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000302 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000310- Issue #8233: When run as a script, py_compile.py optionally takes a single

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

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000425- Issue #8300: When passing a non-integer argument to struct.pack with any
426 integer format code, struct.pack first attempts to convert the non-integer
427 using its __index__ method. If that method is non-existent or raises
428 TypeError it goes on to try the __int__ method, as described below.
429
Georg Brandlba83f822010-03-14 09:50:54 +0000430- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
431 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
432 argument's __int__ method to convert to an integer before packing. It also
433 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
434 was inconsistent: __int__ was used for some integer codes but not for others,
435 and the set of integer codes for which it was used differed between native
436 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000734 file position when calling `truncate()`. It would previously change the file
735 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000736 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

832Core and Builtins
833-----------------
834
Georg Brandlba83f822010-03-14 09:50:54 +0000835- The ``__complex__()`` method is now looked up on the class of instances to
836 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000837
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000838- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
839 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
840
Mark Dickinson1b34d252010-01-01 17:27:30 +0000841- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000842 DeprecationWarning when passed a float argument where an integer was expected.
843 These functions and methods now raise TypeError instead. The majority of the
844 effects of this change are in the extension modules, but some core functions
845 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
846 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000847

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000856- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
857 used to drop the time part of the result.
858
Georg Brandlba83f822010-03-14 09:50:54 +0000859- Issue #1811: Improve accuracy and cross-platform consistency for true division
860 of integers: the result of a/b is now correctly rounded for ints a and b (at
861 least on IEEE 754 platforms), and in particular does not depend on the
862 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000863
Georg Brandlba83f822010-03-14 09:50:54 +0000864- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
865 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
866 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000867
Georg Brandlba83f822010-03-14 09:50:54 +0000868- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000869 executables on OSX.
870
Georg Brandlba83f822010-03-14 09:50:54 +0000871 These executables now work properly with the arch(1) command: ``arch -ppc
872 python`` will start a universal binary version of python in PPC mode (unlike
873 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000874
Georg Brandlba83f822010-03-14 09:50:54 +0000875- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
876 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +0000887- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
888 allowing for a maximum number of tasks within the pool to be completed by the
889 worker before that worker is terminated, and a new one created to replace it.

933 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
934 the same as passing no argument.
935
Georg Brandlba83f822010-03-14 09:50:54 +0000936- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

960 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
961 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00001008- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1009 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001010
Georg Brandlba83f822010-03-14 09:50:54 +00001011- Issue #3382: 'F' formatting for float and complex now convert the result to
1012 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1013 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001014
Georg Brandlba83f822010-03-14 09:50:54 +00001015- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1016 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001017
Georg Brandlba83f822010-03-14 09:50:54 +00001018- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1019 1e-100 used to raise OverflowError, but now gives the requested 120
1020 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001028
Georg Brandlba83f822010-03-14 09:50:54 +00001029- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1030 decimal string that's guaranteed to round back to x under correct rounding
1031 (with round-half-to-even rounding mode). Previously it gave a string based on
1032 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1033 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1034 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001035
Georg Brandlba83f822010-03-14 09:50:54 +00001036- Issue #7117: On almost all platforms: float-to-string and string-to-float
1037 conversions within Python are now correctly rounded. Places these conversions
1038 occur include: str for floats and complex numbers; the float and complex
1039 constructors; old-style and new-style numeric formatting; serialization and
1040 deserialization of floats and complex numbers using marshal, pickle and json;
1041 parsing of float and imaginary literals in Python code; Decimal-to-float
1042 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001043
Georg Brandlba83f822010-03-14 09:50:54 +00001044 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1045 providing correctly-rounded strtod and dtoa C functions. This code is
1046 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1047 the C compiler. There may be a small number of platforms on which correct
1048 operation of this code cannot be guaranteed, so the code is not used: notably,
1049 this applies to platforms where the C double format is not IEEE 754 binary64,
1050 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1051 and Python's configure script is unable to determine how to change the FPU
1052 precision. On these platforms conversions use the platform strtod and dtoa,
1053 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001054
Georg Brandlba83f822010-03-14 09:50:54 +00001055- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1056 uses the correctly-rounded string <-> float conversions described above (when
1057 available), and so produces correctly rounded results that will display nicely
1058 under the float repr. There are two related small changes: (1) round now
1059 accepts any class with an ``__index__()`` method for its second argument (but
1060 no longer accepts floats for the second argument), and (2) an excessively

1441 this code path is really executed because I cannot move to such directory on

1468 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2844
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002845- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2846 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2847 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2848 ``printf`` function, whereas PyString_FromFormat has an independent
2849 implementation and uses "%zd" on all platforms for size_t values.
2850 This makes a difference on win64, where ``printf`` needs "%Id" to display
2851 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002871 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2872 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2873 when given a tuple of classes as second argument, were looking up
2874 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2875 type object.

2946 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2947 for catch_warnings() also led to an improvement in the raising of a
2948 DeprecationWarning related to warnings.warn_explicit().
2949

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003014What's New in Python 2.6 beta 3?
3015================================
3016
Barry Warsaw07a4a382008-08-21 01:15:08 +00003017*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003018
3019Core and Builtins
3020-----------------
3021
Guido van Rossumf8402962008-08-20 15:01:50 +00003022- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3023 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3024 extensions do not automatically benefit from the class attribute
3025 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3026 to their tp_flags field if they care. This is a backwards
3027 compatibility feature; in 3.0, all types will use the cache by
3028 default.
3029
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003030- Keyword arguments can now follow starred arguments. (``f(a, *args,
3031 keyword=23)`` is now valid syntax.)
3032
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003033- ctypes function pointers that are COM methods have a boolean True
3034 value again.
3035
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003036- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3037 by denying s# to parse objects that have a releasebuffer procedure,
3038 and introducing s*.
3039
Georg Brandl1e13ea92008-08-11 09:07:59 +00003040- Issue #3537: Fix an assertion failure when an empty but presized dict
3041 object was stored in the freelist.
3042
Mark Dickinsonb6467572008-08-04 21:30:09 +00003043- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3044 ValueError consistently across platforms.
3045
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003046- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3047 (64bit Unix, for example), unichr() would truncate its argument and return
3048 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3049
Neal Norwitze7d8be82008-07-31 17:17:14 +00003050- Apply security patches from Apple.
3051
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003052- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3053 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3054
Antoine Pitrou92f82162008-07-25 22:22:08 +00003055- Issue #1819: function calls with several named parameters are now on
3056 average 35% faster (as measured by pybench).
3057
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003058- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3059 the python debugger steps into a class statement: the free variables (local
3060 variables defined in an outer scope) would be deleted from the outer scope.
3061
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003062- Issue #2620: Overflow checking when allocating or reallocating memory
3063 was not always being done properly in some python types and extension
3064 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3065 all been updated to perform better checks and places in the code that
3066 would previously leak memory on the error path when such an allocation
3067 failed have been fixed.
3068
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003069Library
3070-------
3071
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003072- Issue #3612: Added some missing basic types in ctypes.wintypes.
3073
Benjamin Petersone977ad42008-08-20 01:42:01 +00003074- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3075 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3076
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003077- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3078 version reported by these tools does not necessarily follow the python
3079 version numbering scheme, so the module is less strict when parsing it.
3080
Nick Coghlanf70385a2008-08-18 12:42:46 +00003081- Issue #2235: Added Py3k warnings for types which will become unhashable
3082 under the stricter __hash__ inheritance rules in 3.0. Several types
3083 which did not meet the rules for hash invariants and were already
3084 unhashable in 3.0 have now been explicitly flagged as unhashable in
3085 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3086 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3087
Brett Cannon88f801d2008-08-18 00:46:22 +00003088- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3092
Brett Cannon46225e72008-08-18 00:36:52 +00003093- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003095- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3096
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003097- Issue #3575: Incremental decoder's decode function now takes bytearray
3098 by using 's*' instead of 't#'.
3099
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003100- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003101 fails unicode conversion on 2nd parameter. (windows only)
3102
Facundo Batista94f243a2008-08-17 03:38:39 +00003103- Issue 2464. urllib2 now supports a malformation in the URL received
3104 in a redirect.
3105
Brett Cannonabe423e2008-08-16 21:47:07 +00003106- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003107 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003108
Facundo Batistaeb90b782008-08-16 14:44:07 +00003109- Issue #2776: fixed small issue when handling an URL with double slash
3110 after a 302 response in the case of not going through a proxy.
3111
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003112- Issue #2676: in the email package, content-type parsing was hanging on
3113 pathological input because of quadratic or exponential behaviour of a
3114 regular expression.
3115
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003116- Issue #3476: binary buffered reading through the new "io" library is now
3117 thread-safe.
3118
Brett Cannonbf3157b2008-08-14 05:00:03 +00003119- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3120 since mimetools itself is deprecated. Because modules are cached, all
3121 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3122
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003123- Issue #3134: shutil referenced undefined WindowsError symbol.
3124
Robert Schuppenies14646332008-08-10 11:01:53 +00003125- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3126 menu entries were not deleted.
3127
Brett Cannon83e81842008-08-09 23:30:55 +00003128- Copied the implementation of reduce() to _functools.reduce() to have a
3129 version that did not raise a DeprecationWarning under -3.
3130
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003131- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3132 a MemoryError rather than silently stop the iteration.
3133
Guido van Rossum59ce9012008-08-09 14:55:34 +00003134- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3135 to _sre.compile() will now be rejected. This should not affect anybody
3136 since the re.compile() function never generates invalid re-bytecode.
3137
Skip Montanaroa032bf42008-08-08 22:52:51 +00003138- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00003157 asking for a specific length. This problem only affected files opened
3158 using the new "io" module, not the built-in open() function.

3185 mode 0600 rather than 000 under Unix.
3186
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003187- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Mark Dickinson64b7e502008-07-16 09:40:03 +00003220- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3221 produced a ValueError instead of giving the correct float.
3222
Eric Smitha5fa5a22008-07-16 00:11:49 +00003223- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3224 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3225
Mark Dickinson7103aa42008-07-15 19:08:33 +00003226- Issue #3008: the float type has a new instance method 'float.hex'
3227 and a new class method 'float.fromhex' to convert floating-point
3228 numbers to and from hexadecimal strings, respectively.
3229
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003230- Issue #2235: __hash__ is once again inherited by default. To allow
3231 collections.Hashable to remain meaningful in the presence of the
3232 default hash implementation (object.__hash__), it is now possible
3233 to explicit block inheritance of hash by setting __hash__=None at
3234 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3235 level.
3236
Nick Coghlanb028f502008-07-13 14:52:36 +00003237- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3238 the parent module cannot be found while performing an absolute import.
3239 This means that an incorrectly defined __package__ attribute will
3240 now only prevent relative imports in that module rather than causing
3241 all imports from that module to fail.
3242
Nick Coghlan14ff9942008-07-08 14:21:42 +00003243- Issue #2517: Allow unicode messages in Exceptions again by correctly

3254
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003255- Issue #3004: Minor change to slice.indices(): the start and stop
3256 arguments are now treated identically, making the behaviour easier
3257 to describe and understand. For example, slice(None, -10,
3258 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3259 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3260 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003262- Issue #3219: Calling a function with repeated keyword arguments,
3263 f(a=2, a=23), would not cause a syntax error. This was a regression
3264 from 2.4 caused by the switch to the new compiler.

3303 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003304 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Issue #1631171: Re-implement the 'warnings' module in C (the
3777 original Python code has been kept as backup). This will allow for
3778 using the 'warning's machinery in such places as the parser where
3779 use of pure Python code is not possible. Both the ``showarning()``
3780 and ``formatwarning()`` gain an optional 'line' argument which is
3781 not called by default for backwards-compatibility reasons. Setting
3782 ``warnings.showwarning()`` to an implementation that lacks support
3783 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- Issue #2550: The approach used by client/server code for obtaining
3847 ports to listen on in network-oriented tests has been refined in an
3848 effort to facilitate running multiple instances of the entire
3849 regression test suite in parallel without issue.
3850 test_support.bind_port() has been fixed such that it will always
3851 return a unique port -- which wasn't always the case with the
3852 previous implementation, especially if socket options had been set
3853 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3854 new implementation of bind_port() will actually raise an exception
3855 if it is passed an AF_INET/SOCK_STREAM socket with either the
3856 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3857 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3858 the socket it's been passed. This currently only applies to
3859 Windows. This option prevents any other sockets from binding to the
3860 host/port we've bound to, thus removing the possibility of the
3861 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3862 when a second SOCK_STREAM socket binds and accepts to a host/port
3863 that's already been bound by another socket. The optional preferred
3864 port parameter to bind_port() has been removed. Under no
3865 circumstances should tests be hard coding ports!
3866
3867 test_support.find_unused_port() has also been introduced, which will
3868 pass a temporary socket object to bind_port() in order to obtain an
3869 unused port. The temporary socket object is then closed and
3870 deleted, and the port is returned. This method should only be used
3871 for obtaining an unused port in order to pass to an external program
3872 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3873 a parameter to a server-oriented class that doesn't give you direct
3874 access to the underlying socket used.
3875
3876 Finally, test_support.HOST has been introduced, which should be used
3877 for the host argument of any relevant socket calls (i.e. bind and
3878 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003879
3880 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003881 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003882 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3883 test_asynchat and test_socket_ssl.
3884
Georg Brandl3ee81df2008-05-17 18:14:43 +00003885 It is now possible for multiple instances of the regression test
3886 suite to run in parallel without issue.

4153-----------------
4154
Fred Drakea8ee94b2008-03-01 02:45:07 +00004155- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004156 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004157
Georg Brandlad61bc82008-02-23 15:11:18 +00004158- Issue #2067: file.__exit__() now calls subclasses' close() method.
4159
4160- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004161
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004162- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004163 issue 215555 for a discussion.
4164
Eric Smitha73fbe72008-02-23 03:09:44 +00004165- Added the future_builtins module, which contains hex() and oct().
4166 These are the PEP 3127 version of these functions, designed to be
4167 compatible with the hex() and oct() builtins from Python 3.0. They
4168 differ slightly in their output formats from the existing, unchanged
4169 Python 2.6 builtins. The expected usage of the future_builtins
4170 module is:
4171 from future_builtins import hex, oct
4172
Eric Smith7ef40bf2008-02-20 23:34:22 +00004173- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4174 exponents for exponents with absolute value < 100. Follows C99
4175 standard. This is a change on Windows, which would use 3 digits.
4176 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4177 so that any alterations it does to the resulting string will be
4178 available in stringlib/formatter.h (for float.__format__).
4179
Eric Smith5a3c1352008-02-19 13:21:56 +00004180- Implemented PEP 3101, Advanced String Formatting. This adds a new
4181 builtin format(); a format() method for str and unicode; a
4182 __format__() method to object, str, unicode, int, long, float, and
4183 datetime; the class string.Formatter; and the C API
4184 PyObject_Format().
4185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Fixed several potential crashes, all caused by specially crafted
4187 __del__ methods exploiting objects in temporarily inconsistent
4188 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004189
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004190- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004191 prevent a possible crash: an Abstract Base Class would try to access
4192 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004193
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Fixed repr() and str() of complex numbers with infinity or nan as
4195 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Clear all free lists during a gc.collect() of the highest generation
4198 in order to allow pymalloc to free more arenas. Python may give back
4199 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004200
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Issue #2045: Fix an infinite recursion triggered when printing a
4202 subclass of collections.defaultdict, if its default_factory is set
4203 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004204
Christian Heimesf75dbef2008-02-08 00:11:31 +00004205- Fixed a minor memory leak in dictobject.c. The content of the free
4206 list was not freed on interpreter shutdown.
4207
Georg Brandl21e99f42010-03-07 15:23:59 +00004208- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4212 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004213 to compact the internal free lists of pre-allocted ints and floats.
4214
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4216 calls. Python expected the return type int but the fork familie
4217 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004218
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4220 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004221
Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4223 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4226 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4229 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004230
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Patch #1473257: generator objects gain a gi_code attribute. This is
4232 the same object as the func_code attribute of the function that
4233 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004234
Georg Brandl3ee81df2008-05-17 18:14:43 +00004235- Issue #1920: "while 0" statements were completely removed by the
4236 compiler, even in the presence of an "else" clause, which is
4237 supposed to be run when the condition is false. Now the compiler
4238 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004239
Guido van Rossumeead05f2008-01-24 18:21:02 +00004240- A few crashers fixed: weakref_in_del.py (issue #1377858);
4241 loosing_dict_ref.py (issue #1303614, test67.py);
4242 borrowed_ref_[34].py (not in tracker).
4243
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004244- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004245 suppressed while an extension is loaded by calling SetErrorMode in
4246 dynload_win.c. The error is still reported properly.
4247
Georg Brandl3ee81df2008-05-17 18:14:43 +00004248- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004249 several extension methods and modules do not work without unicode
4250 support.
4251
Georg Brandl26543b12008-01-21 18:36:51 +00004252- Issue #1882: when compiling code from a string, encoding cookies in the
4253 second line of code were not always recognized correctly.
4254
Georg Brandl14404b62008-01-19 19:27:05 +00004255- Issue #1679: "0x" was taken as a valid integer literal.
4256
Georg Brandl6caad7d2008-01-26 14:19:22 +00004257- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004258 added.
4259
Christian Heimesc94e2b52008-01-14 04:13:37 +00004260- sys.float_info / PyFloat_GetInfo: The floating point information
4261 object was converted from a dict to a specialized structseq object.
4262
Georg Brandl3ee81df2008-05-17 18:14:43 +00004263- Patch #1816: Added sys.flags structseq. It exposes the status of
4264 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004265
Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Objects/structseq.c: Implemented new structseq representation. The
4267 patch makes structseqs (e.g. the return value of os.stat) more
4268 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004269
Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Patch #1700288: added a type attribute cache that caches method
4271 accesses, resulting in speedups in heavily object-oriented code.

4279 envvar and sys.dont_write_bytecode attribute. All these can be set
4280 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004281
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282- Improve some exception messages when Windows fails to load an
4283 extension module. Now we get for example '%1 is not a valid Win32
4284 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004285

Georg Brandl3ee81df2008-05-17 18:14:43 +00004292 and INF. float("nan"), float("inf") and float("-inf") now work on
4293 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004295- Compiler now generates simpler and faster code for dictionary
4296 literals. The oparg for BUILD_MAP now indicates an estimated
4297 dictionary size. There is a new opcode, STORE_MAP, for adding
4298 entries to the dictionary.

4328 file can now be directly executed by passing their name to the
4329 interpreter. The directory/zipfile is automatically inserted as the
4330 first entry in sys.path.

4341
Georg Brandl21e99f42010-03-07 15:23:59 +00004342- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4344 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004345
Georg Brandl3ee81df2008-05-17 18:14:43 +00004346- Issue #1686386: Tuple's tp_repr did not take into account the
4347 possibility of having a self-referential tuple, which is possible
4348 from C code. Nor did object's tp_str consider that a type's tp_str
4349 could do something that could lead to an inifinite recursion.
4350 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4351 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004352
Georg Brandl3ee81df2008-05-17 18:14:43 +00004353- Issue #1164: It was possible to trigger deadlock when using the
4354 'print' statement to write to a file since the GIL was not released
4355 as needed. Now PyObject_Print() does the right thing along with
4356 various tp_print implementations of the built-in types and those in
4357 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004366- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367 PyObject_Call() never calling back out to Python code to trigger
4368 recursion depth updates/checks. Required the creation of a static
4369 RuntimeError instance in case normalizing an exception put the
4370 recursion check value past its limit. Fixes crashers
4371 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004386- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004387 __*__ attributes. (Some already existed, e.g., __doc__ and
4388 __name__.)

4394 calls.
4395
Collin Winter62903052007-05-18 23:11:24 +00004396- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004397 "except E as target:". This is to provide forwards compatibility
4398 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004405- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004406 setting a plain string, ie don't expand to single letter identifiers.
4407
Raymond Hettinger13936692007-04-11 18:40:58 +00004408- Request #1191699: Slices can now be pickled.
4409
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004410- Request #1193128: str.translate() now allows a None argument for
4411 translations that only remove characters without re-mapping the
4412 remaining characters.
4413
Georg Brandl5cb76c12007-03-21 09:00:39 +00004414- Patch #1682205: a TypeError while unpacking an iterable is no longer

4418
Guido van Rossum143b5642007-03-23 04:58:42 +00004419- Bug #1683368: The object.__init__() and object.__new__() methods are
4420 now stricter in rejecting excess arguments. The only time when
4421 either allows excess arguments is when it is not overridden and the
4422 other one is. For backwards compatibility, when both are
4423 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004424 warning later). Also, type.__init__() insists on the same signature
4425 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4428 object to complex using its __complex__() method before falling back
4429 to the __float__() method. Therefore, the functions in the cmath
4430 module now can operate on objects that define a __complex__()
4431 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004432
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433- Patch #1623563: allow __class__ assignment for classes with
4434 __slots__. The old and the new class are still required to have the
4435 same slot names.

4442 its type.

4448
Georg Brandl7b9c5552007-03-12 14:30:05 +00004449- Bug #1678647: write a newline after printing an exception in any
4450 case, even when converting the value to a string failed.
4451
Georg Brandl871f1bc2007-03-12 13:17:36 +00004452- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453 its argument, if it exists. If not, it will work like before. This
4454 allows customizing the output of dir() in the presence of a
4455 __getattr__().

4459
Georg Brandl3ee81df2008-05-17 18:14:43 +00004460- Patch #1675981: remove unreachable code from ``type.__new__()``

4464 parthensized forms. This means complex(repr(x)) now works instead of
4465 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004466
Georg Brandlaa2321b2007-03-07 00:40:28 +00004467- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468 makes the filenames the warning module prints much more sensible
4469 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004470

Georg Brandl0fca97a2007-03-05 22:28:08 +00004482- Patch #1674228: when assigning a slice (old-style), check for the
4483 sq_ass_slice instead of the sq_slice slot.
4484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- When printing an unraisable error, don't print exceptions. before
4486 the name. This duplicates the behavior whening normally printing
4487 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005055 are set for invalid interpolation sequences that would lead to

5112 TestCase and TestSuite subclasses (not instances) are no longer
5113 accepted in TestSuite.addTest(). This should cause no
5114 incompatibility since it never made sense with ordinary subclasses
5115 -- the failure just occurred later, with a more cumbersome
5116 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005403 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005504- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005505 time so that opening a database previously created with the DB_DUP
5506 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5507 opens. Specifically: dictionary assignment to a DB object will
5508 replace all values for a given key when the database allows
5509 duplicate values. DB users should use DB.put(k, v) when they want
5510 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005790 periodic threadstate and signal checking in tight loops. By
5791 default, this option is turned-off. It should only be enabled in

5864
Georg Brandl3ee81df2008-05-17 18:14:43 +00005865- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5866 of w# format code incorrectly truncated the length to an int, even
5867 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5868 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005898- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5899 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005926- Removed the macfs module. It had been deprecated since Python 2.5.
5927 This lead to the deprecation of macostools.touched() as it relied
