35
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000036- Issue #8567: Fix precedence of signals in Decimal module: when a
37 Decimal operation raises multiple signals and more than one of those
38 signals is trapped, the specification determines the order in which
39 the signals should be handled. In many cases this order wasn't
40 being followed, leading to the wrong Python exception being raised.

87
Antoine Pitroufc69af12010-04-24 20:04:58 +000088- Issue #5103: SSL handshake would ignore the socket timeout and block

90
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000091- The do_handshake() method of SSL objects now adjusts the blocking mode of
92 the SSL structure if necessary (as other methods already do).
93
Georg Brandl4341e542010-04-24 09:08:10 +000094- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

110
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000111- Issue #8484: Load all ciphers and digest algorithms when initializing
112 the _ssl extension, such that verification of some SSL certificates
113 doesn't fail because of an "unknown algorithm".
114

139
R. David Murray27ef9372010-04-12 14:26:06 +0000140- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

187Core and Builtins
188-----------------
189
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000190- Issue #7301: Add environment variable $PYTHONWARNINGS.
191
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000192- Issue #8329: Don't return the same lists from select.select when no fds are
193 changed.
194
Mark Dickinson82791672010-04-06 16:47:55 +0000195- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
196 on 64-bit machines. The shift count for either left or right shift is
197 permitted to be up to sys.maxsize.
198
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000199- Ensure that tokenization of identifiers is not affected by locale.
200
Tarek Ziadé00002952010-04-03 08:37:59 +0000201- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Eric Smithd44b2fc2010-04-02 12:30:56 +0000205- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
206 is called with a non-empty format string. This is an effort to
207 future-proof user code. If a derived class does not currently
208 implement __format__ but later adds its own __format__, it would
209 most likely break user code that had supplied a format string. This
210 will be changed to a DeprecationWaring in Python 3.3 and it will be
211 an error in Python 3.4.
212
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000213- Issue #8268: Old-style classes (not just instances) now support weak
214 references.

Georg Brandlba83f822010-03-14 09:50:54 +0000227 (SIGINT). If an error occurs while importing the site module, the error is
228 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000229 module.
230
Collin Winter001a3952010-03-18 21:54:01 +0000231- Code objects now support weak references.

237
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000238- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
239 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
240 and `ssl.OPENSSL_VERSION_NUMBER`.
241
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000242- Issue #8310: Allow dis to examine new style classes.
243
Mark Dickinson8a950712010-04-03 15:47:46 +0000244- Issue #8257: The Decimal construct now accepts a float instance
245 directly, converting that float to a Decimal of equal value:
246
247 >>> Decimal(1.1)

249
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000250- collections.Counter() now supports a subtract() method.
251
Raymond Hettingera551f312010-04-04 18:34:45 +0000252- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000253 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000254
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000255- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000256 old-style comparison functions to new-style key-functions.
257
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000258- Issue #8294: The Fraction constructor now accepts Decimal and float
259 instances directly.
260
Mark Dickinsone096e822010-04-02 10:17:07 +0000261- Issue #7279: Comparisons involving a Decimal signaling NaN now
262 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000263 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
264 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000265
Mark Dickinson99d80962010-04-02 08:53:22 +0000266- Issue #2531: Comparison operations between floats and Decimal

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000271- Issue #8233: When run as a script, py_compile.py optionally takes a single
272 argument `-` which tells it to read files to compile from stdin. Each line
273 is read on demand and the named file is compiled immediately. (Original
274 patch by Piotr Ożarowski).
275
276- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
277 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000278
Florent Xicluna58b65662010-03-30 16:29:03 +0000279- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
280 form feed (0x0C) are now considered linebreaks, as specified in Unicode
281 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000282 http://www.unicode.org/reports/tr14/

Mark Dickinson9588d992010-03-27 11:14:37 +0000284- Comparisons using one of <, <=, >, >= between a complex instance and
285 a Fractions instance now raise TypeError instead of returning
286 True/False. This makes Fraction <=> complex comparisons consistent with
287 int <=> complex, float <=> complex, and complex <=> complex comparisons.
288
Michael Foorde6410c52010-03-29 20:04:23 +0000289- Addition of ``WeakSet`` to the ``weakref`` module.

300 now silenced.
301
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000302- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
303 deprecated.
304
R. David Murrayc9d1a782010-03-22 15:55:09 +0000305- Issue #7860: platform.uname now reports the correct 'machine' type

389 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000391- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
392 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
393 argument's __int__ method to convert to an integer before packing. It also
394 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
395 was inconsistent: __int__ was used for some integer codes but not for others,
396 and the set of integer codes for which it was used differed between native
397 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000695 file position when calling `truncate()`. It would previously change the file
696 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000697 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

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

801
Mark Dickinson1b34d252010-01-01 17:27:30 +0000802- Issue #5080: A number of functions and methods previously produced a

804 These functions and methods now raise TypeError instead. The majority of the
805 effects of this change are in the extension modules, but some core functions
806 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,

Georg Brandlba83f822010-03-14 09:50:54 +0000990- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
991 decimal string that's guaranteed to round back to x under correct rounding
992 (with round-half-to-even rounding mode). Previously it gave a string based on
993 rounding x to 17 decimal digits. repr(x) for a complex number behaves
994 similarly. On platforms where the correctly-rounded strtod and dtoa code is
995 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000996
Georg Brandlba83f822010-03-14 09:50:54 +0000997- Issue #7117: On almost all platforms: float-to-string and string-to-float
998 conversions within Python are now correctly rounded. Places these conversions
999 occur include: str for floats and complex numbers; the float and complex
1000 constructors; old-style and new-style numeric formatting; serialization and
1001 deserialization of floats and complex numbers using marshal, pickle and json;
1002 parsing of float and imaginary literals in Python code; Decimal-to-float
1003 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001004
Georg Brandlba83f822010-03-14 09:50:54 +00001005 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1006 providing correctly-rounded strtod and dtoa C functions. This code is
1007 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1008 the C compiler. There may be a small number of platforms on which correct
1009 operation of this code cannot be guaranteed, so the code is not used: notably,
1010 this applies to platforms where the C double format is not IEEE 754 binary64,
1011 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1012 and Python's configure script is unable to determine how to change the FPU
1013 precision. On these platforms conversions use the platform strtod and dtoa,
1014 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001016- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1017 uses the correctly-rounded string <-> float conversions described above (when
1018 available), and so produces correctly rounded results that will display nicely
1019 under the float repr. There are two related small changes: (1) round now
1020 accepts any class with an ``__index__()`` method for its second argument (but
1021 no longer accepts floats for the second argument), and (2) an excessively
1022 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1023 raises an exception.

1172 but with at least one decimal point and with a default precision
1173 of 12. Previously, the behavior the same but with a default precision of 6.
1174 This more closely matches ``str()``, and reduces surprises when adding

1373
Georg Brandlba83f822010-03-14 09:50:54 +00001374- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

1402 this code path is really executed because I cannot move to such directory on
1403 win2k)

1429 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1430 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001433- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001508- Issue #6816: runpy now provides a run_path function that allows Python code to
1509 execute file paths that refer to source or compiled Python files as well as
1510 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00001511 __main__.py file. This allows applications that run other Python scripts to
1512 support the same flexibility as the CPython command line itself.

1537 from stdin so that existing input does not confuse it and lead to incorrect
1538 entry or an IOError. It also properly flushes it afterwards to avoid the
1539 terminal echoing the input afterwards on OSes such as Solaris.

2805
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002806- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2807 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2808 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2809 ``printf`` function, whereas PyString_FromFormat has an independent
2810 implementation and uses "%zd" on all platforms for size_t values.
2811 This makes a difference on win64, where ``printf`` needs "%Id" to display
2812 64bit values.

2818 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002831- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002832 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2833 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2834 when given a tuple of classes as second argument, were looking up
2835 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2836 type object.

Jesse Noller438195f2009-01-18 21:04:36 +00002931- Issue #4301: Patch the logging module to add processName support, remove
2932 _check_logger_class from multiprocessing.
2933
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002934- Issue #2975: When compiling several extension modules with Visual Studio 2008
2935 from the same python interpreter, some environment variables would grow
2936 without limit.
2937
Benjamin Peterson37346b22008-08-23 20:27:43 +00002938- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2939 exploitation of poor argument checking.

2944 remaining ones have "pysqlite_" prefix.
2945
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002946- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2954 wrapper for warnings.catch_warnings() that makes it easier to check
2955 that expected warning messages are being reported.
2956
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002957- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002975What's New in Python 2.6 beta 3?
2976================================
2977
Barry Warsaw07a4a382008-08-21 01:15:08 +00002978*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002979
2980Core and Builtins
2981-----------------
2982
Guido van Rossumf8402962008-08-20 15:01:50 +00002983- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2984 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2985 extensions do not automatically benefit from the class attribute
2986 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2987 to their tp_flags field if they care. This is a backwards
2988 compatibility feature; in 3.0, all types will use the cache by
2989 default.
2990
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002991- Keyword arguments can now follow starred arguments. (``f(a, *args,
2992 keyword=23)`` is now valid syntax.)
2993
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002994- ctypes function pointers that are COM methods have a boolean True
2995 value again.
2996
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002997- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2998 by denying s# to parse objects that have a releasebuffer procedure,
2999 and introducing s*.
3000
Georg Brandl1e13ea92008-08-11 09:07:59 +00003001- Issue #3537: Fix an assertion failure when an empty but presized dict
3002 object was stored in the freelist.
3003
Mark Dickinsonb6467572008-08-04 21:30:09 +00003004- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3005 ValueError consistently across platforms.
3006
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003007- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3008 (64bit Unix, for example), unichr() would truncate its argument and return
3009 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3010
Neal Norwitze7d8be82008-07-31 17:17:14 +00003011- Apply security patches from Apple.
3012
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003013- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3014 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3015
Antoine Pitrou92f82162008-07-25 22:22:08 +00003016- Issue #1819: function calls with several named parameters are now on
3017 average 35% faster (as measured by pybench).
3018
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003019- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3020 the python debugger steps into a class statement: the free variables (local
3021 variables defined in an outer scope) would be deleted from the outer scope.
3022
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003023- Issue #2620: Overflow checking when allocating or reallocating memory
3024 was not always being done properly in some python types and extension
3025 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3026 all been updated to perform better checks and places in the code that
3027 would previously leak memory on the error path when such an allocation
3028 failed have been fixed.
3029
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003030Library
3031-------
3032
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003033- Issue #3612: Added some missing basic types in ctypes.wintypes.
3034
Benjamin Petersone977ad42008-08-20 01:42:01 +00003035- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3036 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3037
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003038- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3039 version reported by these tools does not necessarily follow the python
3040 version numbering scheme, so the module is less strict when parsing it.
3041
Nick Coghlanf70385a2008-08-18 12:42:46 +00003042- Issue #2235: Added Py3k warnings for types which will become unhashable
3043 under the stricter __hash__ inheritance rules in 3.0. Several types
3044 which did not meet the rules for hash invariants and were already
3045 unhashable in 3.0 have now been explicitly flagged as unhashable in
3046 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3047 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3048
Brett Cannon88f801d2008-08-18 00:46:22 +00003049- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3050 imported into the module but exposed as part of the module's API.
3051
Brett Cannon7b96f072008-08-18 00:41:11 +00003052- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3053
Brett Cannon46225e72008-08-18 00:36:52 +00003054- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003056- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3057
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003058- Issue #3575: Incremental decoder's decode function now takes bytearray
3059 by using 's*' instead of 't#'.
3060
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003061- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003062 fails unicode conversion on 2nd parameter. (windows only)
3063
Facundo Batista94f243a2008-08-17 03:38:39 +00003064- Issue 2464. urllib2 now supports a malformation in the URL received
3065 in a redirect.
3066
Brett Cannonabe423e2008-08-16 21:47:07 +00003067- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003068 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003069
Facundo Batistaeb90b782008-08-16 14:44:07 +00003070- Issue #2776: fixed small issue when handling an URL with double slash
3071 after a 302 response in the case of not going through a proxy.
3072
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003073- Issue #2676: in the email package, content-type parsing was hanging on
3074 pathological input because of quadratic or exponential behaviour of a
3075 regular expression.
3076
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003077- Issue #3476: binary buffered reading through the new "io" library is now
3078 thread-safe.
3079
Brett Cannonbf3157b2008-08-14 05:00:03 +00003080- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3081 since mimetools itself is deprecated. Because modules are cached, all
3082 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3083
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003084- Issue #3134: shutil referenced undefined WindowsError symbol.
3085
Robert Schuppenies14646332008-08-10 11:01:53 +00003086- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3087 menu entries were not deleted.
3088
Brett Cannon83e81842008-08-09 23:30:55 +00003089- Copied the implementation of reduce() to _functools.reduce() to have a
3090 version that did not raise a DeprecationWarning under -3.
3091
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003092- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3093 a MemoryError rather than silently stop the iteration.
3094
Guido van Rossum59ce9012008-08-09 14:55:34 +00003095- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3096 to _sre.compile() will now be rejected. This should not affect anybody
3097 since the re.compile() function never generates invalid re-bytecode.
3098
Skip Montanaroa032bf42008-08-08 22:52:51 +00003099- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3100 upon first access it can be automatically initialized from the csv file if
3101 it wasn't initialized during instantiation.
3102
Brett Cannon3aa2a492008-08-06 22:28:09 +00003103- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3104 the reload() built-in has been removed.
3105
Brett Cannon7e30b672008-08-04 21:52:25 +00003106- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003107 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3115 raised an AttributeError.
3116
Benjamin Peterson01a24322008-07-28 23:35:27 +00003117- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003118 asking for a specific length. This problem only affected files opened
3119 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003120
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003121- Issue #3449: Update decimal module to use most recent specification
3122 (v. 1.68) and tests (v. 2.58) from IBM.
3123
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003124- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3125

3132
3133- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3134 invalid arguments.
3135
3136- Issue #3302: Fix several crashes when calling locale's gettext functions
3137 with None arguments.
3138
3139- Issue #3389: Allow resolving dotted names for handlers in logging
3140 configuration files.
3141
3142- Deprecate the sunaudio module for removal in Python 3.0.
3143
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003144- Issue #3394: zipfile.writestr sets external attributes when passed a
3145 file name rather than a ZipInfo instance, so files are extracted with
3146 mode 0600 rather than 000 under Unix.
3147
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003148- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3149 argument in python 2.5, this broke code that subclassed Popen to include its
3150 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3159
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003160- Issue #2235: the C API function PyObject_HashNotImplemented and its
3161 interaction with the tp_hash slot (added in 2.6b2) are now documented
3162
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003163- Issue #643841: The language reference now provides more detailed
3164 coverage of the lookup process for special methods. The disclaimers
3165 regarding lack of coverage of new-style classes have also been
3166 removed, since the coverage is now fairly reasonable.

3171
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003172*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003174Core and Builtins
3175-----------------
3176
Georg Brandl3e483f62008-07-16 22:57:41 +00003177- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3178 its methods now allow for items objects that can be converted to
3179 an integer using operator.index().
3180
Mark Dickinson64b7e502008-07-16 09:40:03 +00003181- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3182 produced a ValueError instead of giving the correct float.
3183
Eric Smitha5fa5a22008-07-16 00:11:49 +00003184- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3185 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3186
Mark Dickinson7103aa42008-07-15 19:08:33 +00003187- Issue #3008: the float type has a new instance method 'float.hex'
3188 and a new class method 'float.fromhex' to convert floating-point
3189 numbers to and from hexadecimal strings, respectively.
3190
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003191- Issue #2235: __hash__ is once again inherited by default. To allow
3192 collections.Hashable to remain meaningful in the presence of the
3193 default hash implementation (object.__hash__), it is now possible
3194 to explicit block inheritance of hash by setting __hash__=None at
3195 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3196 level.
3197
Nick Coghlanb028f502008-07-13 14:52:36 +00003198- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3199 the parent module cannot be found while performing an absolute import.
3200 This means that an incorrectly defined __package__ attribute will
3201 now only prevent relative imports in that module rather than causing
3202 all imports from that module to fail.
3203
Nick Coghlan14ff9942008-07-08 14:21:42 +00003204- Issue #2517: Allow unicode messages in Exceptions again by correctly
3205 bypassing the instance dictionary when looking up __unicode__ on
3206 new-style classes.
3207
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003208- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3209 set to a custom object whose write() method happens to install
3210 another file in sys.stdout.

3214 another thread's dictionary.
3215
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003216- Issue #3004: Minor change to slice.indices(): the start and stop
3217 arguments are now treated identically, making the behaviour easier

Georg Brandl5cc774e2008-06-11 20:28:06 +00003675 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003676
3677 This is controlled by the configure argument ``--with-universal-archs``:
3678

3680
3681 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3682
3683 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3684
3685 This option should be used in combination with ``--enable-universalsdk=``.

3724 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Issue #1631171: Re-implement the 'warnings' module in C (the
3738 original Python code has been kept as backup). This will allow for
3739 using the 'warning's machinery in such places as the parser where
3740 use of pure Python code is not possible. Both the ``showarning()``
3741 and ``formatwarning()`` gain an optional 'line' argument which is
3742 not called by default for backwards-compatibility reasons. Setting
3743 ``warnings.showwarning()`` to an implementation that lacks support
3744 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Issue #2550: The approach used by client/server code for obtaining
3808 ports to listen on in network-oriented tests has been refined in an
3809 effort to facilitate running multiple instances of the entire
3810 regression test suite in parallel without issue.
3811 test_support.bind_port() has been fixed such that it will always
3812 return a unique port -- which wasn't always the case with the
3813 previous implementation, especially if socket options had been set
3814 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3815 new implementation of bind_port() will actually raise an exception
3816 if it is passed an AF_INET/SOCK_STREAM socket with either the
3817 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3818 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3819 the socket it's been passed. This currently only applies to
3820 Windows. This option prevents any other sockets from binding to the
3821 host/port we've bound to, thus removing the possibility of the
3822 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3823 when a second SOCK_STREAM socket binds and accepts to a host/port
3824 that's already been bound by another socket. The optional preferred
3825 port parameter to bind_port() has been removed. Under no
3826 circumstances should tests be hard coding ports!
3827
3828 test_support.find_unused_port() has also been introduced, which will
3829 pass a temporary socket object to bind_port() in order to obtain an
3830 unused port. The temporary socket object is then closed and
3831 deleted, and the port is returned. This method should only be used
3832 for obtaining an unused port in order to pass to an external program
3833 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3834 a parameter to a server-oriented class that doesn't give you direct
3835 access to the underlying socket used.
3836
3837 Finally, test_support.HOST has been introduced, which should be used
3838 for the host argument of any relevant socket calls (i.e. bind and
3839 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003840
3841 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003842 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003843 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3844 test_asynchat and test_socket_ssl.
3845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846 It is now possible for multiple instances of the regression test
3847 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004116- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004117 644. The mode is now inherited from the py file.

4121- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004122
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004123- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004124 issue 215555 for a discussion.
4125
Eric Smitha73fbe72008-02-23 03:09:44 +00004126- Added the future_builtins module, which contains hex() and oct().
4127 These are the PEP 3127 version of these functions, designed to be
4128 compatible with the hex() and oct() builtins from Python 3.0. They
4129 differ slightly in their output formats from the existing, unchanged
4130 Python 2.6 builtins. The expected usage of the future_builtins
4131 module is:
4132 from future_builtins import hex, oct
4133
Eric Smith7ef40bf2008-02-20 23:34:22 +00004134- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4135 exponents for exponents with absolute value < 100. Follows C99
4136 standard. This is a change on Windows, which would use 3 digits.
4137 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4138 so that any alterations it does to the resulting string will be
4139 available in stringlib/formatter.h (for float.__format__).
4140
Eric Smith5a3c1352008-02-19 13:21:56 +00004141- Implemented PEP 3101, Advanced String Formatting. This adds a new
4142 builtin format(); a format() method for str and unicode; a
4143 __format__() method to object, str, unicode, int, long, float, and
4144 datetime; the class string.Formatter; and the C API
4145 PyObject_Format().
4146
Georg Brandl3ee81df2008-05-17 18:14:43 +00004147- Fixed several potential crashes, all caused by specially crafted
4148 __del__ methods exploiting objects in temporarily inconsistent
4149 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004150
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004151- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152 prevent a possible crash: an Abstract Base Class would try to access
4153 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Clear all free lists during a gc.collect() of the highest generation
4159 in order to allow pymalloc to free more arenas. Python may give back
4160 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- Issue #2045: Fix an infinite recursion triggered when printing a
4163 subclass of collections.defaultdict, if its default_factory is set
4164 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004165
Christian Heimesf75dbef2008-02-08 00:11:31 +00004166- Fixed a minor memory leak in dictobject.c. The content of the free
4167 list was not freed on interpreter shutdown.
4168
Georg Brandl21e99f42010-03-07 15:23:59 +00004169- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4173 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004174 to compact the internal free lists of pre-allocted ints and floats.
4175
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4177 calls. Python expected the return type int but the fork familie
4178 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Issue #1678380: Fix a bug that identifies 0j and -0j when they

4190 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Patch #1473257: generator objects gain a gi_code attribute. This is
4193 the same object as the func_code attribute of the function that
4194 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Issue #1920: "while 0" statements were completely removed by the
4197 compiler, even in the presence of an "else" clause, which is
4198 supposed to be run when the condition is false. Now the compiler
4199 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004200
Guido van Rossumeead05f2008-01-24 18:21:02 +00004201- A few crashers fixed: weakref_in_del.py (issue #1377858);
4202 loosing_dict_ref.py (issue #1303614, test67.py);
4203 borrowed_ref_[34].py (not in tracker).
4204
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004205- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004206 suppressed while an extension is loaded by calling SetErrorMode in
4207 dynload_win.c. The error is still reported properly.
4208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004210 several extension methods and modules do not work without unicode
4211 support.
4212
Georg Brandl26543b12008-01-21 18:36:51 +00004213- Issue #1882: when compiling code from a string, encoding cookies in the
4214 second line of code were not always recognized correctly.
4215
Georg Brandl14404b62008-01-19 19:27:05 +00004216- Issue #1679: "0x" was taken as a valid integer literal.
4217
Georg Brandl6caad7d2008-01-26 14:19:22 +00004218- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004219 added.
4220
Christian Heimesc94e2b52008-01-14 04:13:37 +00004221- sys.float_info / PyFloat_GetInfo: The floating point information
4222 object was converted from a dict to a specialized structseq object.
4223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Patch #1816: Added sys.flags structseq. It exposes the status of
4225 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004226
Georg Brandl3ee81df2008-05-17 18:14:43 +00004227- Objects/structseq.c: Implemented new structseq representation. The
4228 patch makes structseqs (e.g. the return value of os.stat) more
4229 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004230
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004243- Improve some exception messages when Windows fails to load an
4244 extension module. Now we get for example '%1 is not a valid Win32
4245 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004253 and INF. float("nan"), float("inf") and float("-inf") now work on
4254 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004255
Georg Brandl3ee81df2008-05-17 18:14:43 +00004256- Compiler now generates simpler and faster code for dictionary
4257 literals. The oparg for BUILD_MAP now indicates an estimated
4258 dictionary size. There is a new opcode, STORE_MAP, for adding
4259 entries to the dictionary.

4284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- Issue #1460: The utf-7 incremental decoder did not accept truncated
4286 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004287
Georg Brandl3ee81df2008-05-17 18:14:43 +00004288- Patch #1739468: Directories and zipfiles containing a __main__.py
4289 file can now be directly executed by passing their name to the
4290 interpreter. The directory/zipfile is automatically inserted as the
4291 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004292
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Issue #1265: Fix a problem with sys.settrace, if the tracing
4294 function uses a generator expression when at the same time the
4295 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004296
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004297- sets and frozensets now have an isdisjoint() method.
4298
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004299- optimize the performance of builtin.sum().
4300
Neal Norwitz44f326e2007-10-05 05:29:17 +00004301- Fix warnings found by the new version of the Coverity checker.
4302
Georg Brandl21e99f42010-03-07 15:23:59 +00004303- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4305 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004306
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307- Issue #1686386: Tuple's tp_repr did not take into account the
4308 possibility of having a self-referential tuple, which is possible
4309 from C code. Nor did object's tp_str consider that a type's tp_str
4310 could do something that could lead to an inifinite recursion.
4311 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4312 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004313
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Issue #1164: It was possible to trigger deadlock when using the
4315 'print' statement to write to a file since the GIL was not released
4316 as needed. Now PyObject_Print() does the right thing along with
4317 various tp_print implementations of the built-in types and those in
4318 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Issue #1147: Exceptions were directly allowing string exceptions in
4321 their throw() method even though string exceptions no longer
4322 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004323
Georg Brandl3ee81df2008-05-17 18:14:43 +00004324- Issue #1096: Prevent a segfault from getting the repr of a very
4325 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004326
Brett Cannon1e534b52007-09-07 04:18:30 +00004327- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004328 PyObject_Call() never calling back out to Python code to trigger
4329 recursion depth updates/checks. Required the creation of a static
4330 RuntimeError instance in case normalizing an exception put the
4331 recursion check value past its limit. Fixes crashers
4332 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004333
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004347- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348 __*__ attributes. (Some already existed, e.g., __doc__ and
4349 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004350
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004351- Add -3 option to the interpreter to warn about features that are
4352 deprecated and will be changed/removed in Python 3.0.
4353
Georg Brandl2134e752007-05-21 20:34:16 +00004354- Patch #1686487: you can now pass any mapping after '**' in function
4355 calls.
4356
Collin Winter62903052007-05-18 23:11:24 +00004357- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004358 "except E as target:". This is to provide forwards compatibility
4359 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004360
Brett Cannon229cee22007-05-05 01:34:02 +00004361- Deprecate BaseException.message as per PEP 352.
4362
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004364 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004365
Vinay Sajip8549ce32007-05-06 17:53:37 +00004366- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004367 setting a plain string, ie don't expand to single letter identifiers.
4368
Raymond Hettinger13936692007-04-11 18:40:58 +00004369- Request #1191699: Slices can now be pickled.
4370
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004371- Request #1193128: str.translate() now allows a None argument for
4372 translations that only remove characters without re-mapping the
4373 remaining characters.
4374
Georg Brandl5cb76c12007-03-21 09:00:39 +00004375- Patch #1682205: a TypeError while unpacking an iterable is no longer
4376 masked by a generic one with the message "unpack non-sequence".
4377
Neal Norwitzaa754b72007-03-21 06:39:48 +00004378- Remove unused file Python/fmod.c.
4379
Guido van Rossum143b5642007-03-23 04:58:42 +00004380- Bug #1683368: The object.__init__() and object.__new__() methods are
4381 now stricter in rejecting excess arguments. The only time when
4382 either allows excess arguments is when it is not overridden and the
4383 other one is. For backwards compatibility, when both are
4384 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004385 warning later). Also, type.__init__() insists on the same signature
4386 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004387
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4389 object to complex using its __complex__() method before falling back
4390 to the __float__() method. Therefore, the functions in the cmath
4391 module now can operate on objects that define a __complex__()
4392 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004393
Georg Brandl3ee81df2008-05-17 18:14:43 +00004394- Patch #1623563: allow __class__ assignment for classes with
4395 __slots__. The old and the new class are still required to have the
4396 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004397
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004401- Patch #1462488: Python no longer segfaults when
4402 ``object.__reduce_ex__()`` is called with an object that is faking
4403 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004404
Georg Brandl3ee81df2008-05-17 18:14:43 +00004405- Patch #1680015: Don't modify __slots__ tuple if it contains an

4409
Georg Brandl7b9c5552007-03-12 14:30:05 +00004410- Bug #1678647: write a newline after printing an exception in any
4411 case, even when converting the value to a string failed.
4412
Georg Brandl871f1bc2007-03-12 13:17:36 +00004413- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004414 its argument, if it exists. If not, it will work like before. This
4415 allows customizing the output of dir() in the presence of a
4416 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004417
Collin Winter276887b2007-03-12 16:11:39 +00004418- Patch #922167: Python no longer segfaults when faced with infinitely
4419 self-recursive reload() calls (as reported by bug #742342).
4420
Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- Patch #1675981: remove unreachable code from ``type.__new__()``
4422 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004424- Patch #1491866: change the complex() constructor to allow
4425 parthensized forms. This means complex(repr(x)) now works instead of
4426 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004427
Georg Brandlaa2321b2007-03-07 00:40:28 +00004428- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004429 makes the filenames the warning module prints much more sensible
4430 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004431
Georg Brandl49aafc92007-03-07 00:34:46 +00004432- Variant of patch #697613: don't exit the interpreter on a SystemExit
4433 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004434 variable is given, but break into the interactive interpreter just
4435 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004440- Bug #1674503: close the file opened by execfile() in an error
4441 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004442
Georg Brandl0fca97a2007-03-05 22:28:08 +00004443- Patch #1674228: when assigning a slice (old-style), check for the
4444 sq_ass_slice instead of the sq_slice slot.
4445
Georg Brandl3ee81df2008-05-17 18:14:43 +00004446- When printing an unraisable error, don't print exceptions. before
4447 the name. This duplicates the behavior whening normally printing
4448 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004449
Georg Brandl3ee81df2008-05-17 18:14:43 +00004450- Bug #1653736: Properly discard third argument to

4457 created a weakref on itself during a __del__ call for new-style
4458 classes (classic classes still have the bug).

4505
Armin Rigo7ccbca92006-10-04 12:17:45 +00004506- A number of places, including integer negation and absolute value,

5014
Georg Brandl92a6bae2007-03-13 17:43:32 +00005015- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005016 are set for invalid interpolation sequences that would lead to

5073 TestCase and TestSuite subclasses (not instances) are no longer
5074 accepted in TestSuite.addTest(). This should cause no
5075 incompatibility since it never made sense with ordinary subclasses
5076 -- the failure just occurred later, with a more cumbersome
5077 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005358- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5359 with RFC 3207 and forgets any knowledge obtained from the server not
5360 obtained from the TLS negotiation itself. Patch contributed by Bill
5361 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005362
Georg Brandl3ee81df2008-05-17 18:14:43 +00005363- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005364 that the SMTP.starttls() caller no longer needs to call ehlo()
5365 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005366 does not claim to support starttls. Adds the
5367 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- itertools.chain() now has an alternate constructor,

5448 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5449 silently miscode subclasses of those types. Now, it raises a
5450 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005451

Georg Brandl3ee81df2008-05-17 18:14:43 +00005466 time so that opening a database previously created with the DB_DUP
5467 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5468 opens. Specifically: dictionary assignment to a DB object will
5469 replace all values for a given key when the database allows
5470 duplicate values. DB users should use DB.put(k, v) when they want
5471 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005472

5478 characters with ASCII value less than 32. Also, it correctly quotes
5479 dots only if they occur on a single line, as opposed to the previous
5480 behavior of quoting dots if they are the second character of any
5481 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005482

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005750- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005751 periodic threadstate and signal checking in tight loops. By
5752 default, this option is turned-off. It should only be enabled in
5753 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005810
Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5812 to ``PyTuple_SetItem``, it can be used to populate a brand new

5825
Georg Brandl3ee81df2008-05-17 18:14:43 +00005826- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5827 of w# format code incorrectly truncated the length to an int, even
5828 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5829 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005830
Georg Brandl3ee81df2008-05-17 18:14:43 +00005831- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5853 outside of pystate.c and should not be necessary.
5854
Georg Brandl3ee81df2008-05-17 18:14:43 +00005855- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5856 absolute imports. In earlier versions they might have used relative
5857 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005859- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5860 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005861
Georg Brandl3ee81df2008-05-17 18:14:43 +00005862- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5872 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005873

Georg Brandl3ee81df2008-05-17 18:14:43 +00005887- Removed the macfs module. It had been deprecated since Python 2.5.
5888 This lead to the deprecation of macostools.touched() as it relied
5889 solely on macfs and was a no-op under OS X.
