446 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +0100522- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
523 Distutils-based packages with C extension modules may fail because
524 Apple has removed gcc-4.2, the version used to build python.org
525 64-bit/32-bit Pythons. If the user does not explicitly override
526 the default C compiler by setting the CC environment variable,
527 Distutils will now attempt to compile extension modules with clang
528 if gcc-4.2 is required but not found. Also as a convenience, if
529 the user does explicitly set CC, substitute its value as the default
530 compiler in the Distutils LDSHARED configuration variable for OS X.
531 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
532 SDK, neither of which are available in Xcode 4. This change does not
533 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700806- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
807 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
808 interpreter process. This could cause failures in non-Distutils subprocesses
809 and was unreliable since tests or user programs could modify the interpreter
810 environment after Distutils set it. Instead, have Distutils set the the
811 deployment target only in the environment of each build subprocess. It is
812 still possible to globally override the default by setting
813 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
814 greater or equal to the default value, the value with which the interpreter
815 was built.

844 updating the check interval, so if the user decreases the check interval,
845 the ticker doesn't have to wind down to zero from the old starting point
846 before the new interval takes effect. And if the user increases the
847 interval, it makes sure the new limit takes effect right away rather have an
848 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001799- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1800 This prevents user-created self-referencing ordered dictionaries from
1801 becoming permanently uncollectable GC garbage. The downside is that
1802 removing __del__ means that the internal doubly-linked list has to wait for
1803 GC collection rather than freeing memory immediately when the refcnt drops
1804 to zero.

1834
R. David Murray7c4bf552010-08-25 01:45:57 +00001835- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1836 character years even if the message contains RFC822 two character years.

1868 case in Python 2.5 and earlier).
1869
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001870- Issue #9550: a BufferedReader could issue an additional read when the
1871 original read request had been satisfied, which could block indefinitely
1872 when the underlying raw IO channel was e.g. a socket. Report and original
1873 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002624 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2625 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2626 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2646Core and Builtins
2647-----------------
2648
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002649- Issue #7301: Add environment variable $PYTHONWARNINGS.
2650
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002651- Issue #8329: Don't return the same lists from select.select when no fds are
2652 changed.
2653
Georg Brandlfee0f442010-05-22 21:26:21 +00002654- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002655 on 64-bit machines. The shift count for either left or right shift is
2656 permitted to be up to sys.maxsize.
2657
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002658- Ensure that tokenization of identifiers is not affected by locale.
2659
Georg Brandlfee0f442010-05-22 21:26:21 +00002660- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002661
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002662- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2663
Georg Brandlfee0f442010-05-22 21:26:21 +00002664- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2665 with a non-empty format string. This is an effort to future-proof user
2666 code. If a derived class does not currently implement __format__ but later
2667 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002668 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002669 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002670
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002671- Issue #8268: Old-style classes (not just instances) now support weak

2683
Victor Stinner66644262010-03-10 22:30:19 +00002684- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002685 (SIGINT). If an error occurs while importing the site module, the error is
2686 printed and Python exits. Initialize the GIL before importing the site

2701
Georg Brandlfee0f442010-05-22 21:26:21 +00002702- Issue #8257: The Decimal construct now accepts a float instance directly,
2703 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002704
2705 >>> Decimal(1.1)
2706 Decimal('1.100000000000000088817841970012523233890533447265625')
2707
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002708- collections.Counter() now supports a subtract() method.
2709
Georg Brandlfee0f442010-05-22 21:26:21 +00002710- The functools module now has a total_ordering() class decorator to simplify
2711 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002712
Georg Brandlfee0f442010-05-22 21:26:21 +00002713- The functools module also adds cmp_to_key() as a tool to transition old-style
2714 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002715
Georg Brandlfee0f442010-05-22 21:26:21 +00002716- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2717 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00002719- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2720 InvalidOperation instead of returning False. (Comparisons involving a quiet
2721 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2722 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002723
Georg Brandlfee0f442010-05-22 21:26:21 +00002724- Issue #2531: Comparison operations between floats and Decimal instances now
2725 return a result based on the numeric values of the operands; previously they
2726 returned an arbitrary result based on the relative ordering of id(float) and
2727 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002728
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002729- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002730 argument `-` which tells it to read files to compile from stdin. Each line is
2731 read on demand and the named file is compiled immediately. (Original patch by
2732 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002737- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2738 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002739 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002740
Georg Brandlfee0f442010-05-22 21:26:21 +00002741- Comparisons using one of <, <=, >, >= between a complex instance and a
2742 Fractions instance now raise TypeError instead of returning True/False. This
2743 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2744 <=> complex, and complex <=> complex comparisons.

2849 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00002851 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2852 inconsistent: __int__ was used for some integer codes but not for others, and
2853 the set of integer codes for which it was used differed between native packing
2854 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003155 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003161- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003162 file position when calling `truncate()`. It would previously change the file
3163 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003164 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3165
Georg Brandlba83f822010-03-14 09:50:54 +00003166- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3167 class used to represent files stored inside an archive. The new
3168 implementation is significantly faster and can be wrapped in a
3169 ``io.BufferedReader`` object for more speedups. It also solves an issue
3170 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003181- Issue #7748: Since unicode values are supported for some metadata options in
3182 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3183 encoded string for them. This ensures that the upload and register commands
3184 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003455- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3456 decimal string that's guaranteed to round back to x under correct rounding
3457 (with round-half-to-even rounding mode). Previously it gave a string based on
3458 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3459 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3460 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003461
Georg Brandlba83f822010-03-14 09:50:54 +00003462- Issue #7117: On almost all platforms: float-to-string and string-to-float
3463 conversions within Python are now correctly rounded. Places these conversions
3464 occur include: str for floats and complex numbers; the float and complex
3465 constructors; old-style and new-style numeric formatting; serialization and
3466 deserialization of floats and complex numbers using marshal, pickle and json;
3467 parsing of float and imaginary literals in Python code; Decimal-to-float
3468 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003469
Georg Brandlba83f822010-03-14 09:50:54 +00003470 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3471 providing correctly-rounded strtod and dtoa C functions. This code is
3472 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3473 the C compiler. There may be a small number of platforms on which correct
3474 operation of this code cannot be guaranteed, so the code is not used: notably,
3475 this applies to platforms where the C double format is not IEEE 754 binary64,
3476 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3477 and Python's configure script is unable to determine how to change the FPU
3478 precision. On these platforms conversions use the platform strtod and dtoa,
3479 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003481- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3482 uses the correctly-rounded string <-> float conversions described above (when
3483 available), and so produces correctly rounded results that will display nicely
3484 under the float repr. There are two related small changes: (1) round now
3485 accepts any class with an ``__index__()`` method for its second argument (but
3486 no longer accepts floats for the second argument), and (2) an excessively
3487 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3488 raises an exception.

3637 but with at least one decimal point and with a default precision
3638 of 12. Previously, the behavior the same but with a default precision of 6.
3639 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00003865- On windows, ``os.chdir()`` given unicode was not working if

3867 this code path is really executed because I cannot move to such directory on
3868 win2k)

3894 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3895 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3896 of using the replace error handler in PyUnicode_DecodeUTF8().

Georg Brandlba83f822010-03-14 09:50:54 +00005111- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
5112 in the Lib/test directory, which might be read-only for the user running the
5113 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00005114
Georg Brandlba83f822010-03-14 09:50:54 +00005115- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
5116 of an option with no handler.

Georg Brandlba83f822010-03-14 09:50:54 +00005127 leak-chasing test runs give sensible results. The previous method of reaping
5128 threads could return successfully while some Thread objects were still
5129 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005130
Georg Brandlba83f822010-03-14 09:50:54 +00005131- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
5132 runs the risk of causing the worker thread to fail.

5136
R. David Murray14dcd432009-10-14 13:58:07 +00005137- Issue #7058: Added save/restore for things like sys.argv and cwd to
5138 runtest_inner in regrtest, with warnings if the called test modifies them,
5139 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005146- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5147 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005148 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5149 the tests if DISPLAY is defined but can't be used.

5152 regression tests in parallel, shortening the total runtime.

Georg Brandlba83f822010-03-14 09:50:54 +00005154- Issue #5354: New test support function import_fresh_module() makes it easy to
5155 import both normal and optimised versions of modules. test_heapq and
5156 test_warnings have been adjusted to use it, tests for other modules with both
5157 C and Python implementations in the stdlib can be adjusted to use it over
5158 time.

5165
Georg Brandlba83f822010-03-14 09:50:54 +00005166- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5167 should cause a test to be skipped are now done using import_module from test
5168 support, which does the conversion.

5270
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005271- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5272 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5273 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5274 ``printf`` function, whereas PyString_FromFormat has an independent
5275 implementation and uses "%zd" on all platforms for size_t values.
5276 This makes a difference on win64, where ``printf`` needs "%Id" to display
5277 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005279- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5283 object; previously an int would be returned for small values. the __long__
5284 method is allowed to return either an int or a long, but the behaviour of
5285 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005294 was correctly parsed but parsing of subsequent arguments failed.
5295
Vinay Sajip35e3b032008-09-01 14:33:59 +00005296- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005297 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5298 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5299 when given a tuple of classes as second argument, were looking up
5300 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5301 type object.

5395
Jesse Noller438195f2009-01-18 21:04:36 +00005396- Issue #4301: Patch the logging module to add processName support, remove
5397 _check_logger_class from multiprocessing.
5398
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005399- Issue #2975: When compiling several extension modules with Visual Studio 2008
5400 from the same python interpreter, some environment variables would grow
5401 without limit.
5402
Benjamin Peterson37346b22008-08-23 20:27:43 +00005403- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5404 exploitation of poor argument checking.
5405
Gerhard Häringef2276b2008-09-12 13:54:06 +00005406- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5407
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005408- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5409 remaining ones have "pysqlite_" prefix.
5410
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005411- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5419 wrapper for warnings.catch_warnings() that makes it easier to check
5420 that expected warning messages are being reported.
5421
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005422- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005440What's New in Python 2.6 beta 3?
5441================================
5442
Barry Warsaw07a4a382008-08-21 01:15:08 +00005443*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005444
5445Core and Builtins
5446-----------------
5447
Guido van Rossumf8402962008-08-20 15:01:50 +00005448- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5449 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5450 extensions do not automatically benefit from the class attribute
5451 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5452 to their tp_flags field if they care. This is a backwards
5453 compatibility feature; in 3.0, all types will use the cache by
5454 default.
5455
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005456- Keyword arguments can now follow starred arguments. (``f(a, *args,
5457 keyword=23)`` is now valid syntax.)
5458
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005459- ctypes function pointers that are COM methods have a boolean True
5460 value again.
5461
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005462- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5463 by denying s# to parse objects that have a releasebuffer procedure,
5464 and introducing s*.
5465
Georg Brandl1e13ea92008-08-11 09:07:59 +00005466- Issue #3537: Fix an assertion failure when an empty but presized dict
5467 object was stored in the freelist.
5468
Mark Dickinsonb6467572008-08-04 21:30:09 +00005469- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5470 ValueError consistently across platforms.
5471
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005472- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5473 (64bit Unix, for example), unichr() would truncate its argument and return
5474 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5475
Neal Norwitze7d8be82008-07-31 17:17:14 +00005476- Apply security patches from Apple.
5477
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005478- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5479 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5480
Antoine Pitrou92f82162008-07-25 22:22:08 +00005481- Issue #1819: function calls with several named parameters are now on
5482 average 35% faster (as measured by pybench).
5483
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005484- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5485 the python debugger steps into a class statement: the free variables (local
5486 variables defined in an outer scope) would be deleted from the outer scope.
5487
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005488- Issue #2620: Overflow checking when allocating or reallocating memory
5489 was not always being done properly in some python types and extension
5490 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5491 all been updated to perform better checks and places in the code that
5492 would previously leak memory on the error path when such an allocation
5493 failed have been fixed.
5494
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005495Library
5496-------
5497
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005498- Issue #3612: Added some missing basic types in ctypes.wintypes.
5499
Benjamin Petersone977ad42008-08-20 01:42:01 +00005500- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5501 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5502
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005503- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5504 version reported by these tools does not necessarily follow the python
5505 version numbering scheme, so the module is less strict when parsing it.
5506
Nick Coghlanf70385a2008-08-18 12:42:46 +00005507- Issue #2235: Added Py3k warnings for types which will become unhashable
5508 under the stricter __hash__ inheritance rules in 3.0. Several types
5509 which did not meet the rules for hash invariants and were already
5510 unhashable in 3.0 have now been explicitly flagged as unhashable in
5511 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5512 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5513
Brett Cannon88f801d2008-08-18 00:46:22 +00005514- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5515 imported into the module but exposed as part of the module's API.
5516
Brett Cannon7b96f072008-08-18 00:41:11 +00005517- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5518
Brett Cannon46225e72008-08-18 00:36:52 +00005519- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5520
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005521- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5522
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005523- Issue #3575: Incremental decoder's decode function now takes bytearray
5524 by using 's*' instead of 't#'.
5525
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005526- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005527 fails unicode conversion on 2nd parameter. (windows only)
5528
Georg Brandl222e2082010-08-01 22:27:39 +00005529- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005530 in a redirect.
5531
Brett Cannonabe423e2008-08-16 21:47:07 +00005532- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005533 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005534
Facundo Batistaeb90b782008-08-16 14:44:07 +00005535- Issue #2776: fixed small issue when handling an URL with double slash
5536 after a 302 response in the case of not going through a proxy.
5537
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005538- Issue #2676: in the email package, content-type parsing was hanging on
5539 pathological input because of quadratic or exponential behaviour of a
5540 regular expression.
5541
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005542- Issue #3476: binary buffered reading through the new "io" library is now
5543 thread-safe.
5544
Brett Cannonbf3157b2008-08-14 05:00:03 +00005545- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5546 since mimetools itself is deprecated. Because modules are cached, all
5547 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5548
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005549- Issue #3134: shutil referenced undefined WindowsError symbol.
5550
Robert Schuppenies14646332008-08-10 11:01:53 +00005551- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5552 menu entries were not deleted.
5553
Brett Cannon83e81842008-08-09 23:30:55 +00005554- Copied the implementation of reduce() to _functools.reduce() to have a
5555 version that did not raise a DeprecationWarning under -3.
5556
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005557- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5558 a MemoryError rather than silently stop the iteration.
5559
Guido van Rossum59ce9012008-08-09 14:55:34 +00005560- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5561 to _sre.compile() will now be rejected. This should not affect anybody
5562 since the re.compile() function never generates invalid re-bytecode.
5563
Skip Montanaroa032bf42008-08-08 22:52:51 +00005564- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5565 upon first access it can be automatically initialized from the csv file if
5566 it wasn't initialized during instantiation.
5567
Brett Cannon3aa2a492008-08-06 22:28:09 +00005568- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5569 the reload() built-in has been removed.
5570
Brett Cannon7e30b672008-08-04 21:52:25 +00005571- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005572 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005573 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5574 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5575 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5576 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5577 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005578
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005579- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5580 raised an AttributeError.
5581
Benjamin Peterson01a24322008-07-28 23:35:27 +00005582- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005583 asking for a specific length. This problem only affected files opened
5584 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005585
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005586- Issue #3449: Update decimal module to use most recent specification
5587 (v. 1.68) and tests (v. 2.58) from IBM.
5588
Georg Brandl222e2082010-08-01 22:27:39 +00005589- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005590

5593
Georg Brandlf9efabb2008-07-23 15:16:45 +00005594- Deprecate the "ast" parser function aliases.
5595
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005596- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5597
5598- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5599 invalid arguments.
5600
5601- Issue #3302: Fix several crashes when calling locale's gettext functions
5602 with None arguments.
5603
5604- Issue #3389: Allow resolving dotted names for handlers in logging
5605 configuration files.
5606

5608
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005609- Issue #3394: zipfile.writestr sets external attributes when passed a
5610 file name rather than a ZipInfo instance, so files are extracted with
5611 mode 0600 rather than 000 under Unix.
5612
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005613- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5614 argument in python 2.5, this broke code that subclassed Popen to include its
5615 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5624
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005625- Issue #2235: the C API function PyObject_HashNotImplemented and its
5626 interaction with the tp_hash slot (added in 2.6b2) are now documented
5627
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005628- Issue #643841: The language reference now provides more detailed
5629 coverage of the lookup process for special methods. The disclaimers
5630 regarding lack of coverage of new-style classes have also been
5631 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005634What's New in Python 2.6 beta 2?
5635================================
5636
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005637*Release date: 17-Jul-2008*
5638
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005639Core and Builtins
5640-----------------
5641
Georg Brandl3e483f62008-07-16 22:57:41 +00005642- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5643 its methods now allow for items objects that can be converted to
5644 an integer using operator.index().
5645
Mark Dickinson64b7e502008-07-16 09:40:03 +00005646- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5647 produced a ValueError instead of giving the correct float.
5648
Eric Smitha5fa5a22008-07-16 00:11:49 +00005649- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5650 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5651
Mark Dickinson7103aa42008-07-15 19:08:33 +00005652- Issue #3008: the float type has a new instance method 'float.hex'
5653 and a new class method 'float.fromhex' to convert floating-point
5654 numbers to and from hexadecimal strings, respectively.
5655
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005656- Issue #2235: __hash__ is once again inherited by default. To allow
5657 collections.Hashable to remain meaningful in the presence of the
5658 default hash implementation (object.__hash__), it is now possible
5659 to explicit block inheritance of hash by setting __hash__=None at
5660 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5661 level.
5662
Nick Coghlanb028f502008-07-13 14:52:36 +00005663- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5664 the parent module cannot be found while performing an absolute import.
5665 This means that an incorrectly defined __package__ attribute will
5666 now only prevent relative imports in that module rather than causing
5667 all imports from that module to fail.
5668
Nick Coghlan14ff9942008-07-08 14:21:42 +00005669- Issue #2517: Allow unicode messages in Exceptions again by correctly
5670 bypassing the instance dictionary when looking up __unicode__ on
5671 new-style classes.
5672
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005673- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5674 set to a custom object whose write() method happens to install
5675 another file in sys.stdout.
5676
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005677- Issue #3088: Corrected a race condition in classes derived from
5678 threading.local: the first member set by a thread could be saved in
5679 another thread's dictionary.
5680
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005681- Issue #3004: Minor change to slice.indices(): the start and stop
5682 arguments are now treated identically, making the behaviour easier
5683 to describe and understand. For example, slice(None, -10,
5684 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5685 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

6139 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006140 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006141
6142 This is controlled by the configure argument ``--with-universal-archs``:
6143
6144 - ``--with-universal-archs=all``: install 4-way universal
6145
6146 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6147
6148 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6149

6189 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006190
Christian Heimese74c8f22008-04-19 02:23:57 +00006191- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006202- Issue #1631171: Re-implement the 'warnings' module in C (the
6203 original Python code has been kept as backup). This will allow for
6204 using the 'warning's machinery in such places as the parser where
6205 use of pure Python code is not possible. Both the ``showarning()``
6206 and ``formatwarning()`` gain an optional 'line' argument which is
6207 not called by default for backwards-compatibility reasons. Setting
6208 ``warnings.showwarning()`` to an implementation that lacks support
6209 for the ``line`` argument will raise a DeprecationWarning.

6233
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006234- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Issue #2550: The approach used by client/server code for obtaining
6273 ports to listen on in network-oriented tests has been refined in an
6274 effort to facilitate running multiple instances of the entire
6275 regression test suite in parallel without issue.
6276 test_support.bind_port() has been fixed such that it will always
6277 return a unique port -- which wasn't always the case with the
6278 previous implementation, especially if socket options had been set
6279 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6280 new implementation of bind_port() will actually raise an exception
6281 if it is passed an AF_INET/SOCK_STREAM socket with either the
6282 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6283 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6284 the socket it's been passed. This currently only applies to
6285 Windows. This option prevents any other sockets from binding to the
6286 host/port we've bound to, thus removing the possibility of the
6287 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6288 when a second SOCK_STREAM socket binds and accepts to a host/port
6289 that's already been bound by another socket. The optional preferred
6290 port parameter to bind_port() has been removed. Under no
6291 circumstances should tests be hard coding ports!
6292
6293 test_support.find_unused_port() has also been introduced, which will
6294 pass a temporary socket object to bind_port() in order to obtain an
6295 unused port. The temporary socket object is then closed and
6296 deleted, and the port is returned. This method should only be used
6297 for obtaining an unused port in order to pass to an external program
6298 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6299 a parameter to a server-oriented class that doesn't give you direct
6300 access to the underlying socket used.
6301
6302 Finally, test_support.HOST has been introduced, which should be used
6303 for the host argument of any relevant socket calls (i.e. bind and
6304 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006305
6306 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006307 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006308 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6309 test_asynchat and test_socket_ssl.
6310
Georg Brandl3ee81df2008-05-17 18:14:43 +00006311 It is now possible for multiple instances of the regression test
6312 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006591- Added the future_builtins module, which contains hex() and oct().
6592 These are the PEP 3127 version of these functions, designed to be
6593 compatible with the hex() and oct() builtins from Python 3.0. They
6594 differ slightly in their output formats from the existing, unchanged
6595 Python 2.6 builtins. The expected usage of the future_builtins
6596 module is:
6597 from future_builtins import hex, oct
6598
Eric Smith7ef40bf2008-02-20 23:34:22 +00006599- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6600 exponents for exponents with absolute value < 100. Follows C99
6601 standard. This is a change on Windows, which would use 3 digits.
6602 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6603 so that any alterations it does to the resulting string will be
6604 available in stringlib/formatter.h (for float.__format__).
6605
Eric Smith5a3c1352008-02-19 13:21:56 +00006606- Implemented PEP 3101, Advanced String Formatting. This adds a new
6607 builtin format(); a format() method for str and unicode; a
6608 __format__() method to object, str, unicode, int, long, float, and
6609 datetime; the class string.Formatter; and the C API
6610 PyObject_Format().
6611
Georg Brandl3ee81df2008-05-17 18:14:43 +00006612- Fixed several potential crashes, all caused by specially crafted
6613 __del__ methods exploiting objects in temporarily inconsistent
6614 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006615
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006616- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617 prevent a possible crash: an Abstract Base Class would try to access
6618 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006619

Georg Brandl3ee81df2008-05-17 18:14:43 +00006623- Clear all free lists during a gc.collect() of the highest generation
6624 in order to allow pymalloc to free more arenas. Python may give back
6625 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006626
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627- Issue #2045: Fix an infinite recursion triggered when printing a
6628 subclass of collections.defaultdict, if its default_factory is set
6629 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006630
Christian Heimesf75dbef2008-02-08 00:11:31 +00006631- Fixed a minor memory leak in dictobject.c. The content of the free
6632 list was not freed on interpreter shutdown.
6633
Georg Brandl21e99f42010-03-07 15:23:59 +00006634- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006636
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6638 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006639 to compact the internal free lists of pre-allocted ints and floats.
6640
Georg Brandl3ee81df2008-05-17 18:14:43 +00006641- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6642 calls. Python expected the return type int but the fork familie
6643 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006644
Georg Brandl3ee81df2008-05-17 18:14:43 +00006645- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6646 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006647
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6649 with the collections.Sequence API.

6655 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006656
Georg Brandl3ee81df2008-05-17 18:14:43 +00006657- Patch #1473257: generator objects gain a gi_code attribute. This is
6658 the same object as the func_code attribute of the function that
6659 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006660
Georg Brandl3ee81df2008-05-17 18:14:43 +00006661- Issue #1920: "while 0" statements were completely removed by the
6662 compiler, even in the presence of an "else" clause, which is
6663 supposed to be run when the condition is false. Now the compiler
6664 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006665
Guido van Rossumeead05f2008-01-24 18:21:02 +00006666- A few crashers fixed: weakref_in_del.py (issue #1377858);
6667 loosing_dict_ref.py (issue #1303614, test67.py);
6668 borrowed_ref_[34].py (not in tracker).
6669
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006670- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006671 suppressed while an extension is loaded by calling SetErrorMode in
6672 dynload_win.c. The error is still reported properly.
6673
Georg Brandl3ee81df2008-05-17 18:14:43 +00006674- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006675 several extension methods and modules do not work without unicode
6676 support.
6677
Georg Brandl26543b12008-01-21 18:36:51 +00006678- Issue #1882: when compiling code from a string, encoding cookies in the
6679 second line of code were not always recognized correctly.
6680
Georg Brandl14404b62008-01-19 19:27:05 +00006681- Issue #1679: "0x" was taken as a valid integer literal.
6682
Georg Brandl6caad7d2008-01-26 14:19:22 +00006683- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006684 added.
6685
Christian Heimesc94e2b52008-01-14 04:13:37 +00006686- sys.float_info / PyFloat_GetInfo: The floating point information
6687 object was converted from a dict to a specialized structseq object.
6688
Georg Brandl3ee81df2008-05-17 18:14:43 +00006689- Patch #1816: Added sys.flags structseq. It exposes the status of
6690 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006691
Georg Brandl3ee81df2008-05-17 18:14:43 +00006692- Objects/structseq.c: Implemented new structseq representation. The
6693 patch makes structseqs (e.g. the return value of os.stat) more
6694 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006695
Georg Brandl3ee81df2008-05-17 18:14:43 +00006696- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006753- Patch #1739468: Directories and zipfiles containing a __main__.py
6754 file can now be directly executed by passing their name to the
6755 interpreter. The directory/zipfile is automatically inserted as the
6756 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006758- Issue #1265: Fix a problem with sys.settrace, if the tracing
6759 function uses a generator expression when at the same time the
6760 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006761
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006762- sets and frozensets now have an isdisjoint() method.

6767
Georg Brandl21e99f42010-03-07 15:23:59 +00006768- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006769 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6770 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006771
Georg Brandl3ee81df2008-05-17 18:14:43 +00006772- Issue #1686386: Tuple's tp_repr did not take into account the
6773 possibility of having a self-referential tuple, which is possible
6774 from C code. Nor did object's tp_str consider that a type's tp_str
6775 could do something that could lead to an inifinite recursion.
6776 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6777 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006778
Georg Brandl3ee81df2008-05-17 18:14:43 +00006779- Issue #1164: It was possible to trigger deadlock when using the
6780 'print' statement to write to a file since the GIL was not released
6781 as needed. Now PyObject_Print() does the right thing along with
6782 various tp_print implementations of the built-in types and those in
6783 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006784
Georg Brandl3ee81df2008-05-17 18:14:43 +00006785- Issue #1147: Exceptions were directly allowing string exceptions in

6787 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00006792- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793 PyObject_Call() never calling back out to Python code to trigger
6794 recursion depth updates/checks. Required the creation of a static
6795 RuntimeError instance in case normalizing an exception put the
6796 recursion check value past its limit. Fixes crashers
6797 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006812- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006813 __*__ attributes. (Some already existed, e.g., __doc__ and
6814 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006815
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006816- Add -3 option to the interpreter to warn about features that are
6817 deprecated and will be changed/removed in Python 3.0.
6818
Georg Brandl2134e752007-05-21 20:34:16 +00006819- Patch #1686487: you can now pass any mapping after '**' in function
6820 calls.
6821
Collin Winter62903052007-05-18 23:11:24 +00006822- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006823 "except E as target:". This is to provide forwards compatibility
6824 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006831- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006832 setting a plain string, ie don't expand to single letter identifiers.
6833
Raymond Hettinger13936692007-04-11 18:40:58 +00006834- Request #1191699: Slices can now be pickled.
6835
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006836- Request #1193128: str.translate() now allows a None argument for

6838 remaining characters.
6839
Georg Brandl5cb76c12007-03-21 09:00:39 +00006840- Patch #1682205: a TypeError while unpacking an iterable is no longer

6844
Guido van Rossum143b5642007-03-23 04:58:42 +00006845- Bug #1683368: The object.__init__() and object.__new__() methods are
6846 now stricter in rejecting excess arguments. The only time when
6847 either allows excess arguments is when it is not overridden and the
6848 other one is. For backwards compatibility, when both are
6849 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006850 warning later). Also, type.__init__() insists on the same signature
6851 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006852
Georg Brandl3ee81df2008-05-17 18:14:43 +00006853- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6854 object to complex using its __complex__() method before falling back
6855 to the __float__() method. Therefore, the functions in the cmath
6856 module now can operate on objects that define a __complex__()
6857 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006858
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859- Patch #1623563: allow __class__ assignment for classes with

6861 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006862

6868 its type.

6874
Georg Brandl7b9c5552007-03-12 14:30:05 +00006875- Bug #1678647: write a newline after printing an exception in any
6876 case, even when converting the value to a string failed.
6877
Georg Brandl871f1bc2007-03-12 13:17:36 +00006878- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006879 its argument, if it exists. If not, it will work like before. This
6880 allows customizing the output of dir() in the presence of a
6881 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006889- Patch #1491866: change the complex() constructor to allow
6890 parthensized forms. This means complex(repr(x)) now works instead of
6891 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006892
Georg Brandlaa2321b2007-03-07 00:40:28 +00006893- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006894 makes the filenames the warning module prints much more sensible
6895 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006908- Patch #1674228: when assigning a slice (old-style), check for the
6909 sq_ass_slice instead of the sq_slice slot.
6910
Georg Brandl3ee81df2008-05-17 18:14:43 +00006911- When printing an unraisable error, don't print exceptions. before
6912 the name. This duplicates the behavior whening normally printing
6913 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00007480- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007481 are set for invalid interpolation sequences that would lead to

7538 TestCase and TestSuite subclasses (not instances) are no longer
7539 accepted in TestSuite.addTest(). This should cause no
7540 incompatibility since it never made sense with ordinary subclasses
7541 -- the failure just occurred later, with a more cumbersome
7542 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7824 with RFC 3207 and forgets any knowledge obtained from the server not
7825 obtained from the TLS negotiation itself. Patch contributed by Bill
7826 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007827
Georg Brandl3ee81df2008-05-17 18:14:43 +00007828- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007829 that the SMTP.starttls() caller no longer needs to call ehlo()
7830 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007831 does not claim to support starttls. Adds the
7832 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007887- itertools.chain() now has an alternate constructor,

7913 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7914 silently miscode subclasses of those types. Now, it raises a
7915 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007916

Georg Brandl3ee81df2008-05-17 18:14:43 +00007931 time so that opening a database previously created with the DB_DUP
7932 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7933 opens. Specifically: dictionary assignment to a DB object will
7934 replace all values for a given key when the database allows
7935 duplicate values. DB users should use DB.put(k, v) when they want
7936 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007937

7943 characters with ASCII value less than 32. Also, it correctly quotes
7944 dots only if they occur on a single line, as opposed to the previous
7945 behavior of quoting dots if they are the second character of any
7946 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007947

Guido van Rossum7c862f82007-12-13 20:50:10 +00008209- Bug #1608: use -fwrapv when GCC supports it. This is important,
8210 newer GCC versions may optimize away overflow buffer overflow checks
8211 without this option!
8212
Martin v. Löwis63bf1492007-11-12 05:14:05 +00008213- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
8214
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008215- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008216 periodic threadstate and signal checking in tight loops. By
8217 default, this option is turned-off. It should only be enabled in
8218 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008219

8234 returned by python-config if Python was built with --enable-shared
8235 because that prevented the shared library from being used.
8236

8269-----
8270
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Unified naming convention for free lists and their limits. All free
8272 lists in Object/ are named ``free_list``, the counter ``numfree``
8273 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8274 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008275
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8277 to ``PyTuple_SetItem``, it can be used to populate a brand new
8278 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008279
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008280- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

8286- Patch #1720595: add T_BOOL to the range of structmember types.
8287
8288- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8289 ``PyFloat_GetInfo()`` to the float API.
8290
Georg Brandl3ee81df2008-05-17 18:14:43 +00008291- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8292 of w# format code incorrectly truncated the length to an int, even
8293 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8294 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008295
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8314- Fix some leftovers from the conversion from int to Py_ssize_t
8315 (relevant to strings and sequences of more than 2**31 items).
8316
8317- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8318 outside of pystate.c and should not be necessary.
8319
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8321 absolute imports. In earlier versions they might have used relative
8322 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008323
Georg Brandl3ee81df2008-05-17 18:14:43 +00008324- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8325 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008326
Georg Brandl3ee81df2008-05-17 18:14:43 +00008327- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008334- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8335 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8336 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8337 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008338

Georg Brandl3ee81df2008-05-17 18:14:43 +00008352- Removed the macfs module. It had been deprecated since Python 2.5.
8353 This lead to the deprecation of macostools.touched() as it relied
8354 solely on macfs and was a no-op under OS X.
