173Core and Builtins
174-----------------
175
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000176- Issue #7301: Add environment variable $PYTHONWARNINGS.
177
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000178- Issue #8329: Don't return the same lists from select.select when no fds are
179 changed.
180
Mark Dickinson82791672010-04-06 16:47:55 +0000181- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
182 on 64-bit machines. The shift count for either left or right shift is
183 permitted to be up to sys.maxsize.
184
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000185- Ensure that tokenization of identifiers is not affected by locale.

192 is called with a non-empty format string. This is an effort to
193 future-proof user code. If a derived class does not currently
194 implement __format__ but later adds its own __format__, it would
195 most likely break user code that had supplied a format string. This
196 will be changed to a DeprecationWaring in Python 3.3 and it will be
197 an error in Python 3.4.
198
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000199- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000213 (SIGINT). If an error occurs while importing the site module, the error is
214 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000215 module.
216
Collin Winter001a3952010-03-18 21:54:01 +0000217- Code objects now support weak references.

225 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
226 and `ssl.OPENSSL_VERSION_NUMBER`.
227
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000228- Issue #8310: Allow dis to examine new style classes.
229
Mark Dickinson8a950712010-04-03 15:47:46 +0000230- Issue #8257: The Decimal construct now accepts a float instance

Raymond Hettinger34c35b22010-04-03 10:22:00 +0000236- collections.Counter() now supports a subtract() method.
237
Raymond Hettingera551f312010-04-04 18:34:45 +0000238- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000239 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000240
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000241- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000242 old-style comparison functions to new-style key-functions.
243
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000244- Issue #8294: The Fraction constructor now accepts Decimal and float
245 instances directly.
246
Mark Dickinsone096e822010-04-02 10:17:07 +0000247- Issue #7279: Comparisons involving a Decimal signaling NaN now
248 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000249 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
250 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000251
Mark Dickinson99d80962010-04-02 08:53:22 +0000252- Issue #2531: Comparison operations between floats and Decimal

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000257- Issue #8233: When run as a script, py_compile.py optionally takes a single
258 argument `-` which tells it to read files to compile from stdin. Each line
259 is read on demand and the named file is compiled immediately. (Original
260 patch by Piotr Ożarowski).
261
262- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
263 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000264
Florent Xicluna58b65662010-03-30 16:29:03 +0000265- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
266 form feed (0x0C) are now considered linebreaks, as specified in Unicode
267 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000268 http://www.unicode.org/reports/tr14/
269
Mark Dickinson9588d992010-03-27 11:14:37 +0000270- Comparisons using one of <, <=, >, >= between a complex instance and
271 a Fractions instance now raise TypeError instead of returning
272 True/False. This makes Fraction <=> complex comparisons consistent with
273 int <=> complex, float <=> complex, and complex <=> complex comparisons.
274
Michael Foorde6410c52010-03-29 20:04:23 +0000275- Addition of ``WeakSet`` to the ``weakref`` module.

286 now silenced.
287
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000288- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
289 deprecated.

R. David Murrayc9d1a782010-03-22 15:55:09 +0000291- Issue #7860: platform.uname now reports the correct 'machine' type
292 when Python is running in WOW64 mode on 64 bit Windows.

379 argument's __int__ method to convert to an integer before packing. It also
380 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
381 was inconsistent: __int__ was used for some integer codes but not for others,
382 and the set of integer codes for which it was used differed between native
383 packing and standard packing.)

641 strings,
642 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
643 numeric strings corresponding to subnormal values,
644 (3) a memory leak for some values large enough to cause overflow, and
645 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000680- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000681 file position when calling `truncate()`. It would previously change the file
682 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000683 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
684
Benjamin Petersone06f7112010-01-28 02:15:02 +0000685- UserDict is now a new-style class.
686
Georg Brandlba83f822010-03-14 09:50:54 +0000687- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
688 class used to represent files stored inside an archive. The new
689 implementation is significantly faster and can be wrapped in a
690 ``io.BufferedReader`` object for more speedups. It also solves an issue
691 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
692 Patch by Nir Aides.

700 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000701
Georg Brandlba83f822010-03-14 09:50:54 +0000702- Issue #7748: Since unicode values are supported for some metadata options in
703 Distutils, the DistributionMetadata get_* methods will now return an utf-8
704 encoded string for them. This ensures that the upload and register commands
705 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000706
Georg Brandlba83f822010-03-14 09:50:54 +0000707- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000708 headers in multipart/signed MIME parts, which fixes one of the sources of

791 effects of this change are in the extension modules, but some core functions
792 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,

807 of integers: the result of a/b is now correctly rounded for ints a and b (at
808 least on IEEE 754 platforms), and in particular does not depend on the
809 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000976- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
977 decimal string that's guaranteed to round back to x under correct rounding
978 (with round-half-to-even rounding mode). Previously it gave a string based on
979 rounding x to 17 decimal digits. repr(x) for a complex number behaves
980 similarly. On platforms where the correctly-rounded strtod and dtoa code is
981 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000982
Georg Brandlba83f822010-03-14 09:50:54 +0000983- Issue #7117: On almost all platforms: float-to-string and string-to-float
984 conversions within Python are now correctly rounded. Places these conversions
985 occur include: str for floats and complex numbers; the float and complex
986 constructors; old-style and new-style numeric formatting; serialization and
987 deserialization of floats and complex numbers using marshal, pickle and json;
988 parsing of float and imaginary literals in Python code; Decimal-to-float
989 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000990
Georg Brandlba83f822010-03-14 09:50:54 +0000991 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
992 providing correctly-rounded strtod and dtoa C functions. This code is
993 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
994 the C compiler. There may be a small number of platforms on which correct
995 operation of this code cannot be guaranteed, so the code is not used: notably,
996 this applies to platforms where the C double format is not IEEE 754 binary64,
997 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
998 and Python's configure script is unable to determine how to change the FPU
999 precision. On these platforms conversions use the platform strtod and dtoa,
1000 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001002- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1003 uses the correctly-rounded string <-> float conversions described above (when
1004 available), and so produces correctly rounded results that will display nicely
1005 under the float repr. There are two related small changes: (1) round now
1006 accepts any class with an ``__index__()`` method for its second argument (but
1007 no longer accepts floats for the second argument), and (2) an excessively
1008 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1009 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001156- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1157 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1158 but with at least one decimal point and with a default precision
1159 of 12. Previously, the behavior the same but with a default precision of 6.
1160 This more closely matches ``str()``, and reduces surprises when adding
1161 alignment flags to the empty presentation type. This also affects the new
1162 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001302- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1303 existing .py counterpart, override the co_filename attributes of all code

1346 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1347 instances. On a typical machine this saves 3 bytes of memory (on average) per

1359
Georg Brandlba83f822010-03-14 09:50:54 +00001360- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1361 file objects with closefd=False. The file descriptor is still kept open but
1362 the file object behaves like a closed file. The ``FileIO`` object also got a
1363 new readonly attribute ``closefd``.

1382
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001383- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001386- On windows, ``os.chdir()`` given unicode was not working if
1387 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1388 this code path is really executed because I cannot move to such directory on
1389 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001391- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1392 element is temporarily replaced with an equivalent frozenset. But the
1393 eventual KeyError would always report the empty ``frozenset()`` as the missing
1394 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001414- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1415 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1416 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1417 of using the replace error handler in PyUnicode_DecodeUTF8().
1418
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001419- Issue #3739: The unicode-internal encoder now reports the number of characters

1421
Georg Brandlba83f822010-03-14 09:50:54 +00001422- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1423 allocator will be automatically disabled when running under Valgrind. This
1424 gives improved memory leak detection when running under Valgrind, while taking
1425 advantage of pymalloc at other times.

1958 added. addCleanup allows you to add cleanup functions that will be called
Michael Foord07ef4872009-05-02 22:43:34 +00001959 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
1960 allows for much simpler resource allocation and deallocation during tests.

Georg Brandlba83f822010-03-14 09:50:54 +00002232 for *nix machines for negative handles and large int handles. Without this
2233 check it is possible to segfault the interpreter.

Georg Brandlba83f822010-03-14 09:50:54 +00002252 the timestamp in the gzip stream. The default value remains the current time.

Georg Brandlba83f822010-03-14 09:50:54 +00002648 leak-chasing test runs give sensible results. The previous method of reaping
2649 threads could return successfully while some Thread objects were still
2650 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002667- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2668 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002669 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2670 the tests if DISPLAY is defined but can't be used.

2676 import both normal and optimised versions of modules. test_heapq and
2677 test_warnings have been adjusted to use it, tests for other modules with both
2678 C and Python implementations in the stdlib can be adjusted to use it over
2679 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002687- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2688 should cause a test to be skipped are now done using import_module from test
2689 support, which does the conversion.

2791
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002792- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2793 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2794 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2795 ``printf`` function, whereas PyString_FromFormat has an independent
2796 implementation and uses "%zd" on all platforms for size_t values.
2797 This makes a difference on win64, where ``printf`` needs "%Id" to display
2798 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002800- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2804 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002817- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002818 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2819 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2820 when given a tuple of classes as second argument, were looking up
2821 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2822 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002961What's New in Python 2.6 beta 3?
2962================================
2963
Barry Warsaw07a4a382008-08-21 01:15:08 +00002964*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002965
2966Core and Builtins
2967-----------------
2968
Guido van Rossumf8402962008-08-20 15:01:50 +00002969- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2970 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2971 extensions do not automatically benefit from the class attribute
2972 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2973 to their tp_flags field if they care. This is a backwards
2974 compatibility feature; in 3.0, all types will use the cache by
2975 default.
2976
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002977- Keyword arguments can now follow starred arguments. (``f(a, *args,
2978 keyword=23)`` is now valid syntax.)
2979
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002980- ctypes function pointers that are COM methods have a boolean True
2981 value again.
2982
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002983- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2984 by denying s# to parse objects that have a releasebuffer procedure,
2985 and introducing s*.
2986
Georg Brandl1e13ea92008-08-11 09:07:59 +00002987- Issue #3537: Fix an assertion failure when an empty but presized dict
2988 object was stored in the freelist.
2989
Mark Dickinsonb6467572008-08-04 21:30:09 +00002990- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2991 ValueError consistently across platforms.
2992
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002993- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2994 (64bit Unix, for example), unichr() would truncate its argument and return
2995 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2996
Neal Norwitze7d8be82008-07-31 17:17:14 +00002997- Apply security patches from Apple.
2998
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002999- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3000 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3001
Antoine Pitrou92f82162008-07-25 22:22:08 +00003002- Issue #1819: function calls with several named parameters are now on
3003 average 35% faster (as measured by pybench).
3004
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003005- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3006 the python debugger steps into a class statement: the free variables (local
3007 variables defined in an outer scope) would be deleted from the outer scope.
3008
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003009- Issue #2620: Overflow checking when allocating or reallocating memory
3010 was not always being done properly in some python types and extension
3011 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3012 all been updated to perform better checks and places in the code that
3013 would previously leak memory on the error path when such an allocation
3014 failed have been fixed.
3015
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003016Library
3017-------
3018
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003019- Issue #3612: Added some missing basic types in ctypes.wintypes.
3020
Benjamin Petersone977ad42008-08-20 01:42:01 +00003021- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3022 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3023
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003024- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3025 version reported by these tools does not necessarily follow the python
3026 version numbering scheme, so the module is less strict when parsing it.
3027
Nick Coghlanf70385a2008-08-18 12:42:46 +00003028- Issue #2235: Added Py3k warnings for types which will become unhashable
3029 under the stricter __hash__ inheritance rules in 3.0. Several types
3030 which did not meet the rules for hash invariants and were already
3031 unhashable in 3.0 have now been explicitly flagged as unhashable in
3032 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3033 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3034
Brett Cannon88f801d2008-08-18 00:46:22 +00003035- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3036 imported into the module but exposed as part of the module's API.
3037
Brett Cannon7b96f072008-08-18 00:41:11 +00003038- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3039
Brett Cannon46225e72008-08-18 00:36:52 +00003040- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3041
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003042- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3043
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003044- Issue #3575: Incremental decoder's decode function now takes bytearray
3045 by using 's*' instead of 't#'.
3046
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003047- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003048 fails unicode conversion on 2nd parameter. (windows only)
3049
Facundo Batista94f243a2008-08-17 03:38:39 +00003050- Issue 2464. urllib2 now supports a malformation in the URL received
3051 in a redirect.
3052
Brett Cannonabe423e2008-08-16 21:47:07 +00003053- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003054 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003055
Facundo Batistaeb90b782008-08-16 14:44:07 +00003056- Issue #2776: fixed small issue when handling an URL with double slash
3057 after a 302 response in the case of not going through a proxy.
3058
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003059- Issue #2676: in the email package, content-type parsing was hanging on
3060 pathological input because of quadratic or exponential behaviour of a
3061 regular expression.
3062
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003063- Issue #3476: binary buffered reading through the new "io" library is now
3064 thread-safe.
3065
Brett Cannonbf3157b2008-08-14 05:00:03 +00003066- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3067 since mimetools itself is deprecated. Because modules are cached, all
3068 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3069
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003070- Issue #3134: shutil referenced undefined WindowsError symbol.
3071
Robert Schuppenies14646332008-08-10 11:01:53 +00003072- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3073 menu entries were not deleted.
3074
Brett Cannon83e81842008-08-09 23:30:55 +00003075- Copied the implementation of reduce() to _functools.reduce() to have a
3076 version that did not raise a DeprecationWarning under -3.
3077
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003078- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3079 a MemoryError rather than silently stop the iteration.
3080
Guido van Rossum59ce9012008-08-09 14:55:34 +00003081- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3082 to _sre.compile() will now be rejected. This should not affect anybody
3083 since the re.compile() function never generates invalid re-bytecode.
3084
Skip Montanaroa032bf42008-08-08 22:52:51 +00003085- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3086 upon first access it can be automatically initialized from the csv file if
3087 it wasn't initialized during instantiation.
3088
Brett Cannon3aa2a492008-08-06 22:28:09 +00003089- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3090 the reload() built-in has been removed.
3091
Brett Cannon7e30b672008-08-04 21:52:25 +00003092- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003093 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003100- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3101 raised an AttributeError.
3102
Benjamin Peterson01a24322008-07-28 23:35:27 +00003103- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003104 asking for a specific length. This problem only affected files opened
3105 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003106
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003107- Issue #3449: Update decimal module to use most recent specification
3108 (v. 1.68) and tests (v. 2.58) from IBM.
3109
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003110- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3111

3118
3119- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3120 invalid arguments.
3121
3122- Issue #3302: Fix several crashes when calling locale's gettext functions
3123 with None arguments.
3124
3125- Issue #3389: Allow resolving dotted names for handlers in logging
3126 configuration files.
3127
3128- Deprecate the sunaudio module for removal in Python 3.0.
3129
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003130- Issue #3394: zipfile.writestr sets external attributes when passed a
3131 file name rather than a ZipInfo instance, so files are extracted with
3132 mode 0600 rather than 000 under Unix.
3133
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003134- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3135 argument in python 2.5, this broke code that subclassed Popen to include its
3136 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003146- Issue #2235: the C API function PyObject_HashNotImplemented and its
3147 interaction with the tp_hash slot (added in 2.6b2) are now documented
3148
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003149- Issue #643841: The language reference now provides more detailed
3150 coverage of the lookup process for special methods. The disclaimers
3151 regarding lack of coverage of new-style classes have also been
3152 removed, since the coverage is now fairly reasonable.

3156================================
3157
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003158*Release date: 17-Jul-2008*
3159
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003160Core and Builtins
3161-----------------
3162
Georg Brandl3e483f62008-07-16 22:57:41 +00003163- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3164 its methods now allow for items objects that can be converted to
3165 an integer using operator.index().
3166
Mark Dickinson64b7e502008-07-16 09:40:03 +00003167- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3168 produced a ValueError instead of giving the correct float.
3169
Eric Smitha5fa5a22008-07-16 00:11:49 +00003170- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3171 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3172
Mark Dickinson7103aa42008-07-15 19:08:33 +00003173- Issue #3008: the float type has a new instance method 'float.hex'
3174 and a new class method 'float.fromhex' to convert floating-point
3175 numbers to and from hexadecimal strings, respectively.
3176
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003177- Issue #2235: __hash__ is once again inherited by default. To allow
3178 collections.Hashable to remain meaningful in the presence of the
3179 default hash implementation (object.__hash__), it is now possible
3180 to explicit block inheritance of hash by setting __hash__=None at
3181 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3182 level.
3183
Nick Coghlanb028f502008-07-13 14:52:36 +00003184- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3185 the parent module cannot be found while performing an absolute import.
3186 This means that an incorrectly defined __package__ attribute will
3187 now only prevent relative imports in that module rather than causing
3188 all imports from that module to fail.
3189
Nick Coghlan14ff9942008-07-08 14:21:42 +00003190- Issue #2517: Allow unicode messages in Exceptions again by correctly
3191 bypassing the instance dictionary when looking up __unicode__ on
3192 new-style classes.
3193
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003194- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3195 set to a custom object whose write() method happens to install
3196 another file in sys.stdout.
3197
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003198- Issue #3088: Corrected a race condition in classes derived from

3200 another thread's dictionary.
3201
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003202- Issue #3004: Minor change to slice.indices(): the start and stop
3203 arguments are now treated identically, making the behaviour easier
3204 to describe and understand. For example, slice(None, -10,
3205 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3206 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3207 10, -1).
3208
Georg Brandl278fc502008-07-19 12:46:12 +00003209- Issue #3219: Calling a function with repeated keyword arguments,
3210 f(a=2, a=23), would not cause a syntax error. This was a regression
3211 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003661 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003662
3663 This is controlled by the configure argument ``--with-universal-archs``:
3664
3665 - ``--with-universal-archs=all``: install 4-way universal
3666
3667 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3668
3669 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3670

3710 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003723- Issue #1631171: Re-implement the 'warnings' module in C (the
3724 original Python code has been kept as backup). This will allow for
3725 using the 'warning's machinery in such places as the parser where
3726 use of pure Python code is not possible. Both the ``showarning()``
3727 and ``formatwarning()`` gain an optional 'line' argument which is
3728 not called by default for backwards-compatibility reasons. Setting
3729 ``warnings.showwarning()`` to an implementation that lacks support
3730 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003755- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Issue #2550: The approach used by client/server code for obtaining
3794 ports to listen on in network-oriented tests has been refined in an
3795 effort to facilitate running multiple instances of the entire
3796 regression test suite in parallel without issue.
3797 test_support.bind_port() has been fixed such that it will always
3798 return a unique port -- which wasn't always the case with the
3799 previous implementation, especially if socket options had been set
3800 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3801 new implementation of bind_port() will actually raise an exception
3802 if it is passed an AF_INET/SOCK_STREAM socket with either the
3803 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3804 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3805 the socket it's been passed. This currently only applies to
3806 Windows. This option prevents any other sockets from binding to the
3807 host/port we've bound to, thus removing the possibility of the
3808 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3809 when a second SOCK_STREAM socket binds and accepts to a host/port
3810 that's already been bound by another socket. The optional preferred
3811 port parameter to bind_port() has been removed. Under no
3812 circumstances should tests be hard coding ports!
3813
3814 test_support.find_unused_port() has also been introduced, which will
3815 pass a temporary socket object to bind_port() in order to obtain an
3816 unused port. The temporary socket object is then closed and
3817 deleted, and the port is returned. This method should only be used
3818 for obtaining an unused port in order to pass to an external program
3819 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3820 a parameter to a server-oriented class that doesn't give you direct
3821 access to the underlying socket used.
3822
3823 Finally, test_support.HOST has been introduced, which should be used
3824 for the host argument of any relevant socket calls (i.e. bind and
3825 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003826
3827 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003829 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3830 test_asynchat and test_socket_ssl.
3831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832 It is now possible for multiple instances of the regression test
3833 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004037- The bundled libffi copy is now in sync with the recently released
4038 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4040 files are used. On all linux systems the --with-system-ffi
4041 configure option defaults to "yes".

4100-----------------
4101
Fred Drakea8ee94b2008-03-01 02:45:07 +00004102- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004103 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004105- Issue #2067: file.__exit__() now calls subclasses' close() method.
4106
4107- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004108
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004109- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004110 issue 215555 for a discussion.
4111
Eric Smitha73fbe72008-02-23 03:09:44 +00004112- Added the future_builtins module, which contains hex() and oct().
4113 These are the PEP 3127 version of these functions, designed to be
4114 compatible with the hex() and oct() builtins from Python 3.0. They
4115 differ slightly in their output formats from the existing, unchanged
4116 Python 2.6 builtins. The expected usage of the future_builtins
4117 module is:
4118 from future_builtins import hex, oct
4119
Eric Smith7ef40bf2008-02-20 23:34:22 +00004120- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4121 exponents for exponents with absolute value < 100. Follows C99
4122 standard. This is a change on Windows, which would use 3 digits.
4123 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4124 so that any alterations it does to the resulting string will be
4125 available in stringlib/formatter.h (for float.__format__).
4126
Eric Smith5a3c1352008-02-19 13:21:56 +00004127- Implemented PEP 3101, Advanced String Formatting. This adds a new
4128 builtin format(); a format() method for str and unicode; a
4129 __format__() method to object, str, unicode, int, long, float, and
4130 datetime; the class string.Formatter; and the C API
4131 PyObject_Format().
4132
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133- Fixed several potential crashes, all caused by specially crafted
4134 __del__ methods exploiting objects in temporarily inconsistent
4135 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004136
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004137- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138 prevent a possible crash: an Abstract Base Class would try to access
4139 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Fixed repr() and str() of complex numbers with infinity or nan as
4142 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004143
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144- Clear all free lists during a gc.collect() of the highest generation
4145 in order to allow pymalloc to free more arenas. Python may give back
4146 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004147
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Issue #2045: Fix an infinite recursion triggered when printing a
4149 subclass of collections.defaultdict, if its default_factory is set
4150 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004151
Christian Heimesf75dbef2008-02-08 00:11:31 +00004152- Fixed a minor memory leak in dictobject.c. The content of the free
4153 list was not freed on interpreter shutdown.
4154
Georg Brandl21e99f42010-03-07 15:23:59 +00004155- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4159 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004160 to compact the internal free lists of pre-allocted ints and floats.
4161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4163 calls. Python expected the return type int but the fork familie
4164 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4167 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4170 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004171

Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4176 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #1473257: generator objects gain a gi_code attribute. This is
4179 the same object as the func_code attribute of the function that
4180 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Issue #1920: "while 0" statements were completely removed by the
4183 compiler, even in the presence of an "else" clause, which is
4184 supposed to be run when the condition is false. Now the compiler
4185 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004186
Guido van Rossumeead05f2008-01-24 18:21:02 +00004187- A few crashers fixed: weakref_in_del.py (issue #1377858);
4188 loosing_dict_ref.py (issue #1303614, test67.py);
4189 borrowed_ref_[34].py (not in tracker).
4190
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004191- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004192 suppressed while an extension is loaded by calling SetErrorMode in
4193 dynload_win.c. The error is still reported properly.
4194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004196 several extension methods and modules do not work without unicode
4197 support.
4198
Georg Brandl26543b12008-01-21 18:36:51 +00004199- Issue #1882: when compiling code from a string, encoding cookies in the
4200 second line of code were not always recognized correctly.
4201
Georg Brandl14404b62008-01-19 19:27:05 +00004202- Issue #1679: "0x" was taken as a valid integer literal.
4203
Georg Brandl6caad7d2008-01-26 14:19:22 +00004204- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004205 added.
4206
Christian Heimesc94e2b52008-01-14 04:13:37 +00004207- sys.float_info / PyFloat_GetInfo: The floating point information
4208 object was converted from a dict to a specialized structseq object.
4209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Patch #1816: Added sys.flags structseq. It exposes the status of
4211 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004212
Georg Brandl3ee81df2008-05-17 18:14:43 +00004213- Objects/structseq.c: Implemented new structseq representation. The
4214 patch makes structseqs (e.g. the return value of os.stat) more
4215 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Improve some exception messages when Windows fails to load an
4230 extension module. Now we get for example '%1 is not a valid Win32
4231 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004239 and INF. float("nan"), float("inf") and float("-inf") now work on
4240 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Compiler now generates simpler and faster code for dictionary
4243 literals. The oparg for BUILD_MAP now indicates an estimated
4244 dictionary size. There is a new opcode, STORE_MAP, for adding
4245 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Patch #1739468: Directories and zipfiles containing a __main__.py
4275 file can now be directly executed by passing their name to the
4276 interpreter. The directory/zipfile is automatically inserted as the
4277 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004279- Issue #1265: Fix a problem with sys.settrace, if the tracing
4280 function uses a generator expression when at the same time the
4281 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004282
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004283- sets and frozensets now have an isdisjoint() method.
4284

4286
Neal Norwitz44f326e2007-10-05 05:29:17 +00004287- Fix warnings found by the new version of the Coverity checker.
4288
Georg Brandl21e99f42010-03-07 15:23:59 +00004289- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004290 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4291 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004292
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Issue #1686386: Tuple's tp_repr did not take into account the
4294 possibility of having a self-referential tuple, which is possible
4295 from C code. Nor did object's tp_str consider that a type's tp_str
4296 could do something that could lead to an inifinite recursion.
4297 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4298 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004299
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1164: It was possible to trigger deadlock when using the
4301 'print' statement to write to a file since the GIL was not released
4302 as needed. Now PyObject_Print() does the right thing along with
4303 various tp_print implementations of the built-in types and those in
4304 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004305
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Issue #1147: Exceptions were directly allowing string exceptions in
4307 their throw() method even though string exceptions no longer
4308 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004309
Georg Brandl3ee81df2008-05-17 18:14:43 +00004310- Issue #1096: Prevent a segfault from getting the repr of a very
4311 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004312
Brett Cannon1e534b52007-09-07 04:18:30 +00004313- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314 PyObject_Call() never calling back out to Python code to trigger
4315 recursion depth updates/checks. Required the creation of a static
4316 RuntimeError instance in case normalizing an exception put the
4317 recursion check value past its limit. Fixes crashers
4318 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004333- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334 __*__ attributes. (Some already existed, e.g., __doc__ and
4335 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004336
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004337- Add -3 option to the interpreter to warn about features that are
4338 deprecated and will be changed/removed in Python 3.0.
4339
Georg Brandl2134e752007-05-21 20:34:16 +00004340- Patch #1686487: you can now pass any mapping after '**' in function
4341 calls.
4342
Collin Winter62903052007-05-18 23:11:24 +00004343- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344 "except E as target:". This is to provide forwards compatibility
4345 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004346
Brett Cannon229cee22007-05-05 01:34:02 +00004347- Deprecate BaseException.message as per PEP 352.
4348
Georg Brandl3ee81df2008-05-17 18:14:43 +00004349- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004350 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004351
Vinay Sajip8549ce32007-05-06 17:53:37 +00004352- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004353 setting a plain string, ie don't expand to single letter identifiers.
4354
Raymond Hettinger13936692007-04-11 18:40:58 +00004355- Request #1191699: Slices can now be pickled.
4356
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004357- Request #1193128: str.translate() now allows a None argument for
4358 translations that only remove characters without re-mapping the
4359 remaining characters.
4360
Georg Brandl5cb76c12007-03-21 09:00:39 +00004361- Patch #1682205: a TypeError while unpacking an iterable is no longer
4362 masked by a generic one with the message "unpack non-sequence".
4363
Neal Norwitzaa754b72007-03-21 06:39:48 +00004364- Remove unused file Python/fmod.c.
4365
Guido van Rossum143b5642007-03-23 04:58:42 +00004366- Bug #1683368: The object.__init__() and object.__new__() methods are
4367 now stricter in rejecting excess arguments. The only time when
4368 either allows excess arguments is when it is not overridden and the
4369 other one is. For backwards compatibility, when both are
4370 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004371 warning later). Also, type.__init__() insists on the same signature
4372 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004373
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4375 object to complex using its __complex__() method before falling back
4376 to the __float__() method. Therefore, the functions in the cmath
4377 module now can operate on objects that define a __complex__()
4378 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004379
Georg Brandl3ee81df2008-05-17 18:14:43 +00004380- Patch #1623563: allow __class__ assignment for classes with
4381 __slots__. The old and the new class are still required to have the
4382 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004383

4388 ``object.__reduce_ex__()`` is called with an object that is faking
4389 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004390
Georg Brandl3ee81df2008-05-17 18:14:43 +00004391- Patch #1680015: Don't modify __slots__ tuple if it contains an

4395
Georg Brandl7b9c5552007-03-12 14:30:05 +00004396- Bug #1678647: write a newline after printing an exception in any
4397 case, even when converting the value to a string failed.
4398
Georg Brandl871f1bc2007-03-12 13:17:36 +00004399- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004400 its argument, if it exists. If not, it will work like before. This
4401 allows customizing the output of dir() in the presence of a
4402 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004410- Patch #1491866: change the complex() constructor to allow
4411 parthensized forms. This means complex(repr(x)) now works instead of
4412 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004413
Georg Brandlaa2321b2007-03-07 00:40:28 +00004414- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004415 makes the filenames the warning module prints much more sensible
4416 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004417
Georg Brandl49aafc92007-03-07 00:34:46 +00004418- Variant of patch #697613: don't exit the interpreter on a SystemExit
4419 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004420 variable is given, but break into the interactive interpreter just
4421 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00004428
Georg Brandl0fca97a2007-03-05 22:28:08 +00004429- Patch #1674228: when assigning a slice (old-style), check for the
4430 sq_ass_slice instead of the sq_slice slot.
4431
Georg Brandl3ee81df2008-05-17 18:14:43 +00004432- When printing an unraisable error, don't print exceptions. before
4433 the name. This duplicates the behavior whening normally printing
4434 exceptions.

5063 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005344- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5345 with RFC 3207 and forgets any knowledge obtained from the server not
5346 obtained from the TLS negotiation itself. Patch contributed by Bill
5347 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005348
Georg Brandl3ee81df2008-05-17 18:14:43 +00005349- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005350 that the SMTP.starttls() caller no longer needs to call ehlo()
5351 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352 does not claim to support starttls. Adds the
5353 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5354 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005408- itertools.chain() now has an alternate constructor,

5434 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5435 silently miscode subclasses of those types. Now, it raises a
5436 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005437

Georg Brandl3ee81df2008-05-17 18:14:43 +00005452 time so that opening a database previously created with the DB_DUP
5453 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5454 opens. Specifically: dictionary assignment to a DB object will
5455 replace all values for a given key when the database allows
5456 duplicate values. DB users should use DB.put(k, v) when they want
5457 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005458

5464 characters with ASCII value less than 32. Also, it correctly quotes
5465 dots only if they occur on a single line, as opposed to the previous
5466 behavior of quoting dots if they are the second character of any
5467 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005468

5790-----
5791
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Unified naming convention for free lists and their limits. All free
5793 lists in Object/ are named ``free_list``, the counter ``numfree``

5795 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5798 to ``PyTuple_SetItem``, it can be used to populate a brand new

5811
Georg Brandl3ee81df2008-05-17 18:14:43 +00005812- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5813 of w# format code incorrectly truncated the length to an int, even
5814 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5815 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005816
Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5837
5838- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5839 outside of pystate.c and should not be necessary.
5840
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5842 absolute imports. In earlier versions they might have used relative
5843 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005844
Georg Brandl3ee81df2008-05-17 18:14:43 +00005845- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5846 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005847
Georg Brandl3ee81df2008-05-17 18:14:43 +00005848- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5858 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005859

Georg Brandl3ee81df2008-05-17 18:14:43 +00005873- Removed the macfs module. It had been deprecated since Python 2.5.
5874 This lead to the deprecation of macostools.touched() as it relied
5875 solely on macfs and was a no-op under OS X.
