181Core and Builtins
182-----------------
183
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000184- Issue #7301: Add environment variable $PYTHONWARNINGS.
185
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000186- Issue #8329: Don't return the same lists from select.select when no fds are
187 changed.
188
Mark Dickinson82791672010-04-06 16:47:55 +0000189- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
190 on 64-bit machines. The shift count for either left or right shift is
191 permitted to be up to sys.maxsize.
192
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000193- Ensure that tokenization of identifiers is not affected by locale.

200 is called with a non-empty format string. This is an effort to
201 future-proof user code. If a derived class does not currently
202 implement __format__ but later adds its own __format__, it would
203 most likely break user code that had supplied a format string. This
204 will be changed to a DeprecationWaring in Python 3.3 and it will be
205 an error in Python 3.4.
206
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000207- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000221 (SIGINT). If an error occurs while importing the site module, the error is
222 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000223 module.
224

233 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
234 and `ssl.OPENSSL_VERSION_NUMBER`.
235
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000236- Issue #8310: Allow dis to examine new style classes.
237
Mark Dickinson8a950712010-04-03 15:47:46 +0000238- Issue #8257: The Decimal construct now accepts a float instance

Raymond Hettinger34c35b22010-04-03 10:22:00 +0000244- collections.Counter() now supports a subtract() method.
245
Raymond Hettingera551f312010-04-04 18:34:45 +0000246- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000247 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000248
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000249- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000250 old-style comparison functions to new-style key-functions.
251
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000252- Issue #8294: The Fraction constructor now accepts Decimal and float
253 instances directly.
254
Mark Dickinsone096e822010-04-02 10:17:07 +0000255- Issue #7279: Comparisons involving a Decimal signaling NaN now
256 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000257 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
258 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000259
Mark Dickinson99d80962010-04-02 08:53:22 +0000260- Issue #2531: Comparison operations between floats and Decimal

266 argument `-` which tells it to read files to compile from stdin. Each line
267 is read on demand and the named file is compiled immediately. (Original
268 patch by Piotr Ożarowski).
269
270- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
271 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000272
Florent Xicluna58b65662010-03-30 16:29:03 +0000273- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
274 form feed (0x0C) are now considered linebreaks, as specified in Unicode
275 Standard Annex #14. See issue #7643.

279 a Fractions instance now raise TypeError instead of returning
280 True/False. This makes Fraction <=> complex comparisons consistent with
281 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000385- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
386 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
387 argument's __int__ method to convert to an integer before packing. It also
388 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
389 was inconsistent: __int__ was used for some integer codes but not for others,
390 and the set of integer codes for which it was used differed between native
391 packing and standard packing.)

Florent Xicluna985478d2010-03-06 18:52:52 +0000584- The four path modules (genericpath, macpath, ntpath, posixpath) share a
585 common TestCase for some tests: test_genericpath.CommonTest.
586
Georg Brandlba83f822010-03-14 09:50:54 +0000587- Print platform information when running the whole test suite, or using the
588 ``--verbose`` flag.

Georg Brandlba83f822010-03-14 09:50:54 +0000593- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +0000594 is run with the -OO flag. Tests requiring docstrings are skipped.
595
Georg Brandlba83f822010-03-14 09:50:54 +0000596- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
597 now also used by regrtest to run all the tests in a temporary directory. The
598 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
599 Xicluna who helped with the patch.

616 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000617 library would return a bogus result; on Solaris, it was possible to crash the
618 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000631- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
632 and add the additional members returned in an OSVERSIONINFOEX structure. The
633 new members are service_pack_major, service_pack_minor, suite_mask, and
634 product_type.
Eric Smithee931b72010-01-27 00:28:29 +0000635
Georg Brandlba83f822010-03-14 09:50:54 +0000636- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
637 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
638 returning NULL. The macro now returns a statically allocated empty string
639 instead.

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000681- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000682 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000683 Also, raise ValueError rather than TypeError when an unknown TIPC address
684 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000688- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000689 file position when calling `truncate()`. It would previously change the file
690 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000691 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
692
Benjamin Petersone06f7112010-01-28 02:15:02 +0000693- UserDict is now a new-style class.
694
Georg Brandlba83f822010-03-14 09:50:54 +0000695- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
696 class used to represent files stored inside an archive. The new
697 implementation is significantly faster and can be wrapped in a
698 ``io.BufferedReader`` object for more speedups. It also solves an issue
699 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Petersona43f34c2010-01-25 03:31:13 +0000709
Georg Brandlba83f822010-03-14 09:50:54 +0000710- Issue #7748: Since unicode values are supported for some metadata options in
711 Distutils, the DistributionMetadata get_* methods will now return an utf-8
712 encoded string for them. This ensures that the upload and register commands
713 send the correct values to PyPI without any error.

795
Mark Dickinson1b34d252010-01-01 17:27:30 +0000796- Issue #5080: A number of functions and methods previously produced a

798 These functions and methods now raise TypeError instead. The majority of the
799 effects of this change are in the extension modules, but some core functions
800 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
801 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000984- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
985 decimal string that's guaranteed to round back to x under correct rounding
986 (with round-half-to-even rounding mode). Previously it gave a string based on
987 rounding x to 17 decimal digits. repr(x) for a complex number behaves
988 similarly. On platforms where the correctly-rounded strtod and dtoa code is
989 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000990
Georg Brandlba83f822010-03-14 09:50:54 +0000991- Issue #7117: On almost all platforms: float-to-string and string-to-float
992 conversions within Python are now correctly rounded. Places these conversions
993 occur include: str for floats and complex numbers; the float and complex
994 constructors; old-style and new-style numeric formatting; serialization and
995 deserialization of floats and complex numbers using marshal, pickle and json;
996 parsing of float and imaginary literals in Python code; Decimal-to-float
997 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000998
Georg Brandlba83f822010-03-14 09:50:54 +0000999 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1000 providing correctly-rounded strtod and dtoa C functions. This code is
1001 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1002 the C compiler. There may be a small number of platforms on which correct
1003 operation of this code cannot be guaranteed, so the code is not used: notably,
1004 this applies to platforms where the C double format is not IEEE 754 binary64,
1005 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1006 and Python's configure script is unable to determine how to change the FPU
1007 precision. On these platforms conversions use the platform strtod and dtoa,
1008 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001009
Georg Brandlba83f822010-03-14 09:50:54 +00001010- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1011 uses the correctly-rounded string <-> float conversions described above (when
1012 available), and so produces correctly rounded results that will display nicely
1013 under the float repr. There are two related small changes: (1) round now
1014 accepts any class with an ``__index__()`` method for its second argument (but
1015 no longer accepts floats for the second argument), and (2) an excessively
1016 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1017 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001164- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1165 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1166 but with at least one decimal point and with a default precision
1167 of 12. Previously, the behavior the same but with a default precision of 6.
1168 This more closely matches ``str()``, and reduces surprises when adding
1169 alignment flags to the empty presentation type. This also affects the new
1170 complex.__format__ in the same way.
1171

1367
Georg Brandlba83f822010-03-14 09:50:54 +00001368- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1369 file objects with closefd=False. The file descriptor is still kept open but
1370 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001394- On windows, ``os.chdir()`` given unicode was not working if

1396 this code path is really executed because I cannot move to such directory on
1397 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001399- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1400 element is temporarily replaced with an equivalent frozenset. But the
1401 eventual KeyError would always report the empty ``frozenset()`` as the missing

1423 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1424 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1425 of using the replace error handler in PyUnicode_DecodeUTF8().
1426
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001427- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001430- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2799
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002800- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2801 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2802 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2803 ``printf`` function, whereas PyString_FromFormat has an independent
2804 implementation and uses "%zd" on all platforms for size_t values.
2805 This makes a difference on win64, where ``printf`` needs "%Id" to display
2806 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002808- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2812 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002825- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002826 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2827 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2828 when given a tuple of classes as second argument, were looking up
2829 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2830 type object.

Jesse Noller438195f2009-01-18 21:04:36 +00002925- Issue #4301: Patch the logging module to add processName support, remove
2926 _check_logger_class from multiprocessing.
2927
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002928- Issue #2975: When compiling several extension modules with Visual Studio 2008
2929 from the same python interpreter, some environment variables would grow
2930 without limit.
2931
Benjamin Peterson37346b22008-08-23 20:27:43 +00002932- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

2948 wrapper for warnings.catch_warnings() that makes it easier to check
2949 that expected warning messages are being reported.
2950

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002969What's New in Python 2.6 beta 3?
2970================================
2971
Barry Warsaw07a4a382008-08-21 01:15:08 +00002972*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002973
2974Core and Builtins
2975-----------------
2976
Guido van Rossumf8402962008-08-20 15:01:50 +00002977- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2978 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2979 extensions do not automatically benefit from the class attribute
2980 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2981 to their tp_flags field if they care. This is a backwards
2982 compatibility feature; in 3.0, all types will use the cache by
2983 default.
2984
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002985- Keyword arguments can now follow starred arguments. (``f(a, *args,
2986 keyword=23)`` is now valid syntax.)
2987
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002988- ctypes function pointers that are COM methods have a boolean True
2989 value again.
2990
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002991- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2992 by denying s# to parse objects that have a releasebuffer procedure,
2993 and introducing s*.
2994
Georg Brandl1e13ea92008-08-11 09:07:59 +00002995- Issue #3537: Fix an assertion failure when an empty but presized dict
2996 object was stored in the freelist.
2997
Mark Dickinsonb6467572008-08-04 21:30:09 +00002998- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2999 ValueError consistently across platforms.
3000
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003001- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3002 (64bit Unix, for example), unichr() would truncate its argument and return
3003 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3004
Neal Norwitze7d8be82008-07-31 17:17:14 +00003005- Apply security patches from Apple.
3006
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003007- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3008 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3009
Antoine Pitrou92f82162008-07-25 22:22:08 +00003010- Issue #1819: function calls with several named parameters are now on
3011 average 35% faster (as measured by pybench).
3012
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003013- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3014 the python debugger steps into a class statement: the free variables (local
3015 variables defined in an outer scope) would be deleted from the outer scope.
3016
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003017- Issue #2620: Overflow checking when allocating or reallocating memory
3018 was not always being done properly in some python types and extension
3019 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3020 all been updated to perform better checks and places in the code that
3021 would previously leak memory on the error path when such an allocation
3022 failed have been fixed.
3023
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003024Library
3025-------
3026
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003027- Issue #3612: Added some missing basic types in ctypes.wintypes.
3028
Benjamin Petersone977ad42008-08-20 01:42:01 +00003029- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3030 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3031
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003032- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3033 version reported by these tools does not necessarily follow the python
3034 version numbering scheme, so the module is less strict when parsing it.
3035
Nick Coghlanf70385a2008-08-18 12:42:46 +00003036- Issue #2235: Added Py3k warnings for types which will become unhashable
3037 under the stricter __hash__ inheritance rules in 3.0. Several types
3038 which did not meet the rules for hash invariants and were already
3039 unhashable in 3.0 have now been explicitly flagged as unhashable in
3040 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3041 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3042
Brett Cannon88f801d2008-08-18 00:46:22 +00003043- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3044 imported into the module but exposed as part of the module's API.
3045
Brett Cannon7b96f072008-08-18 00:41:11 +00003046- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3047
Brett Cannon46225e72008-08-18 00:36:52 +00003048- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003050- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3051
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003052- Issue #3575: Incremental decoder's decode function now takes bytearray
3053 by using 's*' instead of 't#'.
3054
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003055- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003056 fails unicode conversion on 2nd parameter. (windows only)
3057
Facundo Batista94f243a2008-08-17 03:38:39 +00003058- Issue 2464. urllib2 now supports a malformation in the URL received
3059 in a redirect.
3060
Brett Cannonabe423e2008-08-16 21:47:07 +00003061- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003062 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003063
Facundo Batistaeb90b782008-08-16 14:44:07 +00003064- Issue #2776: fixed small issue when handling an URL with double slash
3065 after a 302 response in the case of not going through a proxy.
3066
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003067- Issue #2676: in the email package, content-type parsing was hanging on
3068 pathological input because of quadratic or exponential behaviour of a
3069 regular expression.
3070
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003071- Issue #3476: binary buffered reading through the new "io" library is now
3072 thread-safe.
3073
Brett Cannonbf3157b2008-08-14 05:00:03 +00003074- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3075 since mimetools itself is deprecated. Because modules are cached, all
3076 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3077
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003078- Issue #3134: shutil referenced undefined WindowsError symbol.
3079
Robert Schuppenies14646332008-08-10 11:01:53 +00003080- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3081 menu entries were not deleted.
3082
Brett Cannon83e81842008-08-09 23:30:55 +00003083- Copied the implementation of reduce() to _functools.reduce() to have a
3084 version that did not raise a DeprecationWarning under -3.
3085
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003086- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3087 a MemoryError rather than silently stop the iteration.
3088
Guido van Rossum59ce9012008-08-09 14:55:34 +00003089- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3090 to _sre.compile() will now be rejected. This should not affect anybody
3091 since the re.compile() function never generates invalid re-bytecode.
3092
Skip Montanaroa032bf42008-08-08 22:52:51 +00003093- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3094 upon first access it can be automatically initialized from the csv file if
3095 it wasn't initialized during instantiation.
3096
Brett Cannon3aa2a492008-08-06 22:28:09 +00003097- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3098 the reload() built-in has been removed.
3099
Brett Cannon7e30b672008-08-04 21:52:25 +00003100- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003101 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3104 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3105 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3106 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003107
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003108- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3109 raised an AttributeError.
3110
Benjamin Peterson01a24322008-07-28 23:35:27 +00003111- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003112 asking for a specific length. This problem only affected files opened
3113 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003114
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003115- Issue #3449: Update decimal module to use most recent specification
3116 (v. 1.68) and tests (v. 2.58) from IBM.
3117
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003118- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

3126
3127- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3128 invalid arguments.
3129
3130- Issue #3302: Fix several crashes when calling locale's gettext functions
3131 with None arguments.
3132
3133- Issue #3389: Allow resolving dotted names for handlers in logging
3134 configuration files.
3135
3136- Deprecate the sunaudio module for removal in Python 3.0.
3137
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003138- Issue #3394: zipfile.writestr sets external attributes when passed a
3139 file name rather than a ZipInfo instance, so files are extracted with
3140 mode 0600 rather than 000 under Unix.
3141
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003142- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3143 argument in python 2.5, this broke code that subclassed Popen to include its
3144 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3152-------------
3153
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003154- Issue #2235: the C API function PyObject_HashNotImplemented and its
3155 interaction with the tp_hash slot (added in 2.6b2) are now documented
3156
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003157- Issue #643841: The language reference now provides more detailed
3158 coverage of the lookup process for special methods. The disclaimers
3159 regarding lack of coverage of new-style classes have also been
3160 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003163What's New in Python 2.6 beta 2?
3164================================
3165
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003166*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003168Core and Builtins
3169-----------------
3170
Georg Brandl3e483f62008-07-16 22:57:41 +00003171- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3172 its methods now allow for items objects that can be converted to
3173 an integer using operator.index().
3174
Mark Dickinson64b7e502008-07-16 09:40:03 +00003175- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3176 produced a ValueError instead of giving the correct float.
3177
Eric Smitha5fa5a22008-07-16 00:11:49 +00003178- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3179 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3180
Mark Dickinson7103aa42008-07-15 19:08:33 +00003181- Issue #3008: the float type has a new instance method 'float.hex'
3182 and a new class method 'float.fromhex' to convert floating-point
3183 numbers to and from hexadecimal strings, respectively.
3184
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003185- Issue #2235: __hash__ is once again inherited by default. To allow
3186 collections.Hashable to remain meaningful in the presence of the
3187 default hash implementation (object.__hash__), it is now possible
3188 to explicit block inheritance of hash by setting __hash__=None at
3189 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3190 level.
3191
Nick Coghlanb028f502008-07-13 14:52:36 +00003192- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3193 the parent module cannot be found while performing an absolute import.
3194 This means that an incorrectly defined __package__ attribute will
3195 now only prevent relative imports in that module rather than causing
3196 all imports from that module to fail.
3197
Nick Coghlan14ff9942008-07-08 14:21:42 +00003198- Issue #2517: Allow unicode messages in Exceptions again by correctly
3199 bypassing the instance dictionary when looking up __unicode__ on
3200 new-style classes.
3201
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003202- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3203 set to a custom object whose write() method happens to install
3204 another file in sys.stdout.
3205
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003206- Issue #3088: Corrected a race condition in classes derived from

3208 another thread's dictionary.
3209
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003210- Issue #3004: Minor change to slice.indices(): the start and stop
3211 arguments are now treated identically, making the behaviour easier
3212 to describe and understand. For example, slice(None, -10,
3213 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3214 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

3668 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003669 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003670
3671 This is controlled by the configure argument ``--with-universal-archs``:
3672
3673 - ``--with-universal-archs=all``: install 4-way universal
3674
3675 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3676
3677 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3678

3718 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Issue #1631171: Re-implement the 'warnings' module in C (the
3732 original Python code has been kept as backup). This will allow for
3733 using the 'warning's machinery in such places as the parser where
3734 use of pure Python code is not possible. Both the ``showarning()``
3735 and ``formatwarning()`` gain an optional 'line' argument which is
3736 not called by default for backwards-compatibility reasons. Setting
3737 ``warnings.showwarning()`` to an implementation that lacks support
3738 for the ``line`` argument will raise a DeprecationWarning.

3762
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003763- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Issue #2550: The approach used by client/server code for obtaining
3802 ports to listen on in network-oriented tests has been refined in an
3803 effort to facilitate running multiple instances of the entire
3804 regression test suite in parallel without issue.
3805 test_support.bind_port() has been fixed such that it will always
3806 return a unique port -- which wasn't always the case with the
3807 previous implementation, especially if socket options had been set
3808 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3809 new implementation of bind_port() will actually raise an exception
3810 if it is passed an AF_INET/SOCK_STREAM socket with either the
3811 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3812 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3813 the socket it's been passed. This currently only applies to
3814 Windows. This option prevents any other sockets from binding to the
3815 host/port we've bound to, thus removing the possibility of the
3816 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3817 when a second SOCK_STREAM socket binds and accepts to a host/port
3818 that's already been bound by another socket. The optional preferred
3819 port parameter to bind_port() has been removed. Under no
3820 circumstances should tests be hard coding ports!
3821
3822 test_support.find_unused_port() has also been introduced, which will
3823 pass a temporary socket object to bind_port() in order to obtain an
3824 unused port. The temporary socket object is then closed and
3825 deleted, and the port is returned. This method should only be used
3826 for obtaining an unused port in order to pass to an external program
3827 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3828 a parameter to a server-oriented class that doesn't give you direct
3829 access to the underlying socket used.
3830
3831 Finally, test_support.HOST has been introduced, which should be used
3832 for the host argument of any relevant socket calls (i.e. bind and
3833 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003834
3835 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003836 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003837 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3838 test_asynchat and test_socket_ssl.
3839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840 It is now possible for multiple instances of the regression test
3841 suite to run in parallel without issue.

4109
Fred Drakea8ee94b2008-03-01 02:45:07 +00004110- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004111 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004113- Issue #2067: file.__exit__() now calls subclasses' close() method.
4114
4115- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004116
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004117- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004118 issue 215555 for a discussion.
4119
Eric Smitha73fbe72008-02-23 03:09:44 +00004120- Added the future_builtins module, which contains hex() and oct().
4121 These are the PEP 3127 version of these functions, designed to be
4122 compatible with the hex() and oct() builtins from Python 3.0. They
4123 differ slightly in their output formats from the existing, unchanged
4124 Python 2.6 builtins. The expected usage of the future_builtins
4125 module is:
4126 from future_builtins import hex, oct
4127
Eric Smith7ef40bf2008-02-20 23:34:22 +00004128- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4129 exponents for exponents with absolute value < 100. Follows C99
4130 standard. This is a change on Windows, which would use 3 digits.
4131 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4132 so that any alterations it does to the resulting string will be
4133 available in stringlib/formatter.h (for float.__format__).
4134
Eric Smith5a3c1352008-02-19 13:21:56 +00004135- Implemented PEP 3101, Advanced String Formatting. This adds a new
4136 builtin format(); a format() method for str and unicode; a
4137 __format__() method to object, str, unicode, int, long, float, and
4138 datetime; the class string.Formatter; and the C API
4139 PyObject_Format().
4140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Fixed several potential crashes, all caused by specially crafted
4142 __del__ methods exploiting objects in temporarily inconsistent
4143 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004144
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004145- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146 prevent a possible crash: an Abstract Base Class would try to access
4147 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004148
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149- Fixed repr() and str() of complex numbers with infinity or nan as
4150 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Clear all free lists during a gc.collect() of the highest generation
4153 in order to allow pymalloc to free more arenas. Python may give back
4154 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004155
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156- Issue #2045: Fix an infinite recursion triggered when printing a
4157 subclass of collections.defaultdict, if its default_factory is set
4158 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004159
Christian Heimesf75dbef2008-02-08 00:11:31 +00004160- Fixed a minor memory leak in dictobject.c. The content of the free
4161 list was not freed on interpreter shutdown.
4162
Georg Brandl21e99f42010-03-07 15:23:59 +00004163- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4167 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004168 to compact the internal free lists of pre-allocted ints and floats.
4169
Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4171 calls. Python expected the return type int but the fork familie
4172 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004173
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4175 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004176
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4178 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4181 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4184 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Patch #1473257: generator objects gain a gi_code attribute. This is
4187 the same object as the func_code attribute of the function that
4188 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #1920: "while 0" statements were completely removed by the
4191 compiler, even in the presence of an "else" clause, which is
4192 supposed to be run when the condition is false. Now the compiler
4193 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004194
Guido van Rossumeead05f2008-01-24 18:21:02 +00004195- A few crashers fixed: weakref_in_del.py (issue #1377858);
4196 loosing_dict_ref.py (issue #1303614, test67.py);
4197 borrowed_ref_[34].py (not in tracker).
4198
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004199- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004200 suppressed while an extension is loaded by calling SetErrorMode in
4201 dynload_win.c. The error is still reported properly.
4202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004204 several extension methods and modules do not work without unicode
4205 support.
4206
Georg Brandl26543b12008-01-21 18:36:51 +00004207- Issue #1882: when compiling code from a string, encoding cookies in the
4208 second line of code were not always recognized correctly.
4209
Georg Brandl14404b62008-01-19 19:27:05 +00004210- Issue #1679: "0x" was taken as a valid integer literal.
4211
Georg Brandl6caad7d2008-01-26 14:19:22 +00004212- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004213 added.
4214
Christian Heimesc94e2b52008-01-14 04:13:37 +00004215- sys.float_info / PyFloat_GetInfo: The floating point information
4216 object was converted from a dict to a specialized structseq object.
4217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Patch #1816: Added sys.flags structseq. It exposes the status of
4219 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Objects/structseq.c: Implemented new structseq representation. The
4222 patch makes structseqs (e.g. the return value of os.stat) more
4223 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Patch #1700288: added a type attribute cache that caches method
4226 accesses, resulting in speedups in heavily object-oriented code.

4234 envvar and sys.dont_write_bytecode attribute. All these can be set
4235 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004236
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237- Improve some exception messages when Windows fails to load an
4238 extension module. Now we get for example '%1 is not a valid Win32
4239 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004246- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004247 and INF. float("nan"), float("inf") and float("-inf") now work on
4248 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004249
Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Compiler now generates simpler and faster code for dictionary
4251 literals. The oparg for BUILD_MAP now indicates an estimated
4252 dictionary size. There is a new opcode, STORE_MAP, for adding
4253 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004282- Patch #1739468: Directories and zipfiles containing a __main__.py
4283 file can now be directly executed by passing their name to the
4284 interpreter. The directory/zipfile is automatically inserted as the
4285 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004286
Georg Brandl3ee81df2008-05-17 18:14:43 +00004287- Issue #1265: Fix a problem with sys.settrace, if the tracing
4288 function uses a generator expression when at the same time the
4289 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004290
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004291- sets and frozensets now have an isdisjoint() method.
4292

4294
Neal Norwitz44f326e2007-10-05 05:29:17 +00004295- Fix warnings found by the new version of the Coverity checker.
4296
Georg Brandl21e99f42010-03-07 15:23:59 +00004297- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4299 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004300
Georg Brandl3ee81df2008-05-17 18:14:43 +00004301- Issue #1686386: Tuple's tp_repr did not take into account the
4302 possibility of having a self-referential tuple, which is possible
4303 from C code. Nor did object's tp_str consider that a type's tp_str
4304 could do something that could lead to an inifinite recursion.
4305 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4306 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004307
Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- Issue #1164: It was possible to trigger deadlock when using the
4309 'print' statement to write to a file since the GIL was not released
4310 as needed. Now PyObject_Print() does the right thing along with
4311 various tp_print implementations of the built-in types and those in
4312 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004313
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Issue #1147: Exceptions were directly allowing string exceptions in
4315 their throw() method even though string exceptions no longer
4316 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004317
Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Issue #1096: Prevent a segfault from getting the repr of a very
4319 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004320
Brett Cannon1e534b52007-09-07 04:18:30 +00004321- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004322 PyObject_Call() never calling back out to Python code to trigger
4323 recursion depth updates/checks. Required the creation of a static
4324 RuntimeError instance in case normalizing an exception put the
4325 recursion check value past its limit. Fixes crashers
4326 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004327

Neal Norwitz0ac60192007-05-27 04:08:54 +00004341- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342 __*__ attributes. (Some already existed, e.g., __doc__ and
4343 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004344
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004345- Add -3 option to the interpreter to warn about features that are
4346 deprecated and will be changed/removed in Python 3.0.
4347
Georg Brandl2134e752007-05-21 20:34:16 +00004348- Patch #1686487: you can now pass any mapping after '**' in function
4349 calls.
4350
Collin Winter62903052007-05-18 23:11:24 +00004351- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352 "except E as target:". This is to provide forwards compatibility
4353 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004354
Brett Cannon229cee22007-05-05 01:34:02 +00004355- Deprecate BaseException.message as per PEP 352.
4356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004358 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004359
Vinay Sajip8549ce32007-05-06 17:53:37 +00004360- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004361 setting a plain string, ie don't expand to single letter identifiers.
4362
Raymond Hettinger13936692007-04-11 18:40:58 +00004363- Request #1191699: Slices can now be pickled.
4364
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004365- Request #1193128: str.translate() now allows a None argument for
4366 translations that only remove characters without re-mapping the
4367 remaining characters.
4368
Georg Brandl5cb76c12007-03-21 09:00:39 +00004369- Patch #1682205: a TypeError while unpacking an iterable is no longer
4370 masked by a generic one with the message "unpack non-sequence".
4371
Neal Norwitzaa754b72007-03-21 06:39:48 +00004372- Remove unused file Python/fmod.c.
4373
Guido van Rossum143b5642007-03-23 04:58:42 +00004374- Bug #1683368: The object.__init__() and object.__new__() methods are
4375 now stricter in rejecting excess arguments. The only time when
4376 either allows excess arguments is when it is not overridden and the
4377 other one is. For backwards compatibility, when both are
4378 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004379 warning later). Also, type.__init__() insists on the same signature
4380 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004381
Georg Brandl3ee81df2008-05-17 18:14:43 +00004382- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4383 object to complex using its __complex__() method before falling back
4384 to the __float__() method. Therefore, the functions in the cmath
4385 module now can operate on objects that define a __complex__()
4386 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004387
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388- Patch #1623563: allow __class__ assignment for classes with
4389 __slots__. The old and the new class are still required to have the
4390 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004391
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004395- Patch #1462488: Python no longer segfaults when
4396 ``object.__reduce_ex__()`` is called with an object that is faking
4397 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004398
Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Patch #1680015: Don't modify __slots__ tuple if it contains an

4403
Georg Brandl7b9c5552007-03-12 14:30:05 +00004404- Bug #1678647: write a newline after printing an exception in any
4405 case, even when converting the value to a string failed.
4406
Georg Brandl871f1bc2007-03-12 13:17:36 +00004407- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004408 its argument, if it exists. If not, it will work like before. This
4409 allows customizing the output of dir() in the presence of a
4410 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004411
Collin Winter276887b2007-03-12 16:11:39 +00004412- Patch #922167: Python no longer segfaults when faced with infinitely
4413 self-recursive reload() calls (as reported by bug #742342).
4414
Georg Brandl3ee81df2008-05-17 18:14:43 +00004415- Patch #1675981: remove unreachable code from ``type.__new__()``
4416 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004418- Patch #1491866: change the complex() constructor to allow
4419 parthensized forms. This means complex(repr(x)) now works instead of
4420 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004421
Georg Brandlaa2321b2007-03-07 00:40:28 +00004422- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004423 makes the filenames the warning module prints much more sensible
4424 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004425
Georg Brandl49aafc92007-03-07 00:34:46 +00004426- Variant of patch #697613: don't exit the interpreter on a SystemExit
4427 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004428 variable is given, but break into the interactive interpreter just
4429 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004434- Bug #1674503: close the file opened by execfile() in an error
4435 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004436
Georg Brandl0fca97a2007-03-05 22:28:08 +00004437- Patch #1674228: when assigning a slice (old-style), check for the
4438 sq_ass_slice instead of the sq_slice slot.
4439
Georg Brandl3ee81df2008-05-17 18:14:43 +00004440- When printing an unraisable error, don't print exceptions. before
4441 the name. This duplicates the behavior whening normally printing
4442 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- Bug #1653736: Properly discard third argument to

4451 created a weakref on itself during a __del__ call for new-style
4452 classes (classic classes still have the bug).

4499
Armin Rigo7ccbca92006-10-04 12:17:45 +00004500- A number of places, including integer negation and absolute value,

5008
Georg Brandl92a6bae2007-03-13 17:43:32 +00005009- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005010 are set for invalid interpolation sequences that would lead to

5067 TestCase and TestSuite subclasses (not instances) are no longer
5068 accepted in TestSuite.addTest(). This should cause no
5069 incompatibility since it never made sense with ordinary subclasses
5070 -- the failure just occurred later, with a more cumbersome
5071 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005352- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5353 with RFC 3207 and forgets any knowledge obtained from the server not
5354 obtained from the TLS negotiation itself. Patch contributed by Bill
5355 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005356
Georg Brandl3ee81df2008-05-17 18:14:43 +00005357- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005358 that the SMTP.starttls() caller no longer needs to call ehlo()
5359 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005360 does not claim to support starttls. Adds the
5361 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5442 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5443 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00005445

Georg Brandl3ee81df2008-05-17 18:14:43 +00005460 time so that opening a database previously created with the DB_DUP
5461 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5462 opens. Specifically: dictionary assignment to a DB object will
5463 replace all values for a given key when the database allows
5464 duplicate values. DB users should use DB.put(k, v) when they want
5465 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005466

5472 characters with ASCII value less than 32. Also, it correctly quotes
5473 dots only if they occur on a single line, as opposed to the previous
5474 behavior of quoting dots if they are the second character of any
5475 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005476

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005744- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005745 periodic threadstate and signal checking in tight loops. By
5746 default, this option is turned-off. It should only be enabled in
5747 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005804
Georg Brandl3ee81df2008-05-17 18:14:43 +00005805- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5806 to ``PyTuple_SetItem``, it can be used to populate a brand new

5819
Georg Brandl3ee81df2008-05-17 18:14:43 +00005820- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5821 of w# format code incorrectly truncated the length to an int, even
5822 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5823 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005824
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5847 outside of pystate.c and should not be necessary.
5848
Georg Brandl3ee81df2008-05-17 18:14:43 +00005849- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5850 absolute imports. In earlier versions they might have used relative
5851 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005852
Georg Brandl3ee81df2008-05-17 18:14:43 +00005853- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5854 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005855
Georg Brandl3ee81df2008-05-17 18:14:43 +00005856- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5866 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005867

Georg Brandl3ee81df2008-05-17 18:14:43 +00005881- Removed the macfs module. It had been deprecated since Python 2.5.
5882 This lead to the deprecation of macostools.touched() as it relied
5883 solely on macfs and was a no-op under OS X.
