Ned Deily0d0ea482012-02-10 12:59:06 +0100582- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
583 Distutils-based packages with C extension modules may fail because
584 Apple has removed gcc-4.2, the version used to build python.org
585 64-bit/32-bit Pythons. If the user does not explicitly override
586 the default C compiler by setting the CC environment variable,
587 Distutils will now attempt to compile extension modules with clang
588 if gcc-4.2 is required but not found. Also as a convenience, if
589 the user does explicitly set CC, substitute its value as the default
590 compiler in the Distutils LDSHARED configuration variable for OS X.
591 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
592 SDK, neither of which are available in Xcode 4. This change does not

Ned Deily87e82bb2011-06-28 19:52:59 -0700866- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
867 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
868 interpreter process. This could cause failures in non-Distutils subprocesses
869 and was unreliable since tests or user programs could modify the interpreter
870 environment after Distutils set it. Instead, have Distutils set the the
871 deployment target only in the environment of each build subprocess. It is
872 still possible to globally override the default by setting
873 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
874 greater or equal to the default value, the value with which the interpreter
875 was built.

905 the ticker doesn't have to wind down to zero from the old starting point

907 interval, it makes sure the new limit takes effect right away rather have an
908 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001859- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1860 This prevents user-created self-referencing ordered dictionaries from
1861 becoming permanently uncollectable GC garbage. The downside is that
1862 removing __del__ means that the internal doubly-linked list has to wait for
1863 GC collection rather than freeing memory immediately when the refcnt drops
1864 to zero.

1873 original error is re-raised.

1894
R. David Murray7c4bf552010-08-25 01:45:57 +00001895- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1896 character years even if the message contains RFC822 two character years.
1897
Daniel Stutzbach91287322010-08-24 21:09:30 +00001898- Issue #8750: Fixed MutableSet's methods to correctly handle

1933 patch by Jason V. Miller.

Georg Brandlfee0f442010-05-22 21:26:21 +00002583- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2584 the method could block indefinitely if called just before the event loop
2585 started running. This also fixes the occasional freezes witnessed in
2586 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00002588- Issue #5103: SSL handshake would ignore the socket timeout and block
2589 indefinitely if the other end didn't respond.
2590
Georg Brandlfee0f442010-05-22 21:26:21 +00002591- The do_handshake() method of SSL objects now adjusts the blocking mode of the
2592 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +00002602- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
2603 string "python" as the *ident*. openlog() arguments are all optional and
2604 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002684 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2707-----------------
2708
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002709- Issue #7301: Add environment variable $PYTHONWARNINGS.
2710
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002711- Issue #8329: Don't return the same lists from select.select when no fds are
2712 changed.
2713
Georg Brandlfee0f442010-05-22 21:26:21 +00002714- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002715 on 64-bit machines. The shift count for either left or right shift is
2716 permitted to be up to sys.maxsize.
2717
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002718- Ensure that tokenization of identifiers is not affected by locale.

2723
Georg Brandlfee0f442010-05-22 21:26:21 +00002724- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2725 with a non-empty format string. This is an effort to future-proof user
2726 code. If a derived class does not currently implement __format__ but later
2727 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002728 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002729 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002762- Issue #8257: The Decimal construct now accepts a float instance directly,
2763 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002764

2767
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002768- collections.Counter() now supports a subtract() method.
2769
Georg Brandlfee0f442010-05-22 21:26:21 +00002770- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00002779- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2780 InvalidOperation instead of returning False. (Comparisons involving a quiet
2781 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2782 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002783
Georg Brandlfee0f442010-05-22 21:26:21 +00002784- Issue #2531: Comparison operations between floats and Decimal instances now
2785 return a result based on the numeric values of the operands; previously they
2786 returned an arbitrary result based on the relative ordering of id(float) and
2787 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002789- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002790 argument `-` which tells it to read files to compile from stdin. Each line is
2791 read on demand and the named file is compiled immediately. (Original patch by

2798 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002799 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00002801- Comparisons using one of <, <=, >, >= between a complex instance and a
2802 Fractions instance now raise TypeError instead of returning True/False. This
2803 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2804 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003222 file position when calling `truncate()`. It would previously change the file
3223 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003224 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3227 class used to represent files stored inside an archive. The new
3228 implementation is significantly faster and can be wrapped in a
3229 ``io.BufferedReader`` object for more speedups. It also solves an issue
3230 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3319-----------------
3320
Georg Brandlba83f822010-03-14 09:50:54 +00003321- The ``__complex__()`` method is now looked up on the class of instances to
3322 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003323
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003324- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3325 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3326
Mark Dickinson1b34d252010-01-01 17:27:30 +00003327- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003328 DeprecationWarning when passed a float argument where an integer was expected.
3329 These functions and methods now raise TypeError instead. The majority of the
3330 effects of this change are in the extension modules, but some core functions
3331 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3332 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00003333

3343 used to drop the time part of the result.
3344
Georg Brandlba83f822010-03-14 09:50:54 +00003345- Issue #1811: Improve accuracy and cross-platform consistency for true division
3346 of integers: the result of a/b is now correctly rounded for ints a and b (at
3347 least on IEEE 754 platforms), and in particular does not depend on the
3348 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003349
Georg Brandlba83f822010-03-14 09:50:54 +00003350- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3351 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3352 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003355 executables on OSX.
3356
Georg Brandlba83f822010-03-14 09:50:54 +00003357 These executables now work properly with the arch(1) command: ``arch -ppc
3358 python`` will start a universal binary version of python in PPC mode (unlike
3359 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003382 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

3421
Georg Brandlba83f822010-03-14 09:50:54 +00003422- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

3516 decimal string that's guaranteed to round back to x under correct rounding
3517 (with round-half-to-even rounding mode). Previously it gave a string based on

3524 occur include: str for floats and complex numbers; the float and complex
3525 constructors; old-style and new-style numeric formatting; serialization and

3532 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3533 the C compiler. There may be a small number of platforms on which correct
3534 operation of this code cannot be guaranteed, so the code is not used: notably,
3535 this applies to platforms where the C double format is not IEEE 754 binary64,
3536 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3537 and Python's configure script is unable to determine how to change the FPU
3538 precision. On these platforms conversions use the platform strtod and dtoa,
3539 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003541- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3542 uses the correctly-rounded string <-> float conversions described above (when
3543 available), and so produces correctly rounded results that will display nicely
3544 under the float repr. There are two related small changes: (1) round now
3545 accepts any class with an ``__index__()`` method for its second argument (but
3546 no longer accepts floats for the second argument), and (2) an excessively
3547 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3548 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003765- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003766 untrackable objects are not tracked by the garbage collector. This can reduce
3767 the size of collections and therefore the garbage collection overhead on
3768 long-running programs, depending on their particular use of datatypes.

3809
Georg Brandl29c6a282009-04-05 20:23:13 +00003810- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003811 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00003841- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3842 existing .py counterpart, override the co_filename attributes of all code
3843 objects if the original filename is obsolete (which can happen if the file has
3844 been renamed, moved, or if it is accessed through different paths). Patch by

3898
Georg Brandlba83f822010-03-14 09:50:54 +00003899- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3900 file objects with closefd=False. The file descriptor is still kept open but
3901 the file object behaves like a closed file. The ``FileIO`` object also got a
3902 new readonly attribute ``closefd``.

3921
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003922- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003925- On windows, ``os.chdir()`` given unicode was not working if
3926 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3927 this code path is really executed because I cannot move to such directory on
3928 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003930- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3931 element is temporarily replaced with an equivalent frozenset. But the
3932 eventual KeyError would always report the empty ``frozenset()`` as the missing

3954 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3955 step. This avoids problems with counting UTF-8 bytes that ignores the effect

3957
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003958- Issue #3739: The unicode-internal encoder now reports the number of characters

3963 gives improved memory leak detection when running under Valgrind, while taking
3964 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005125 - Packing a float now always gives a Deprecation Warning. Previously it
5126 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005127
Georg Brandlba83f822010-03-14 09:50:54 +00005128 - If x is not an int, long or float, then packing x will always result in
5129 struct.error. Previously an x with an __int__ method could be packed by
5130 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5131 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5132 neither __int__ nor __long__, TypeError used to be raised (with a
5133 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5134 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005135
Georg Brandlba83f822010-03-14 09:50:54 +00005136 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
5137 argument with an __int__ method can be packed, but use of this feature
5138 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005331- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5332 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5333 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5334 ``printf`` function, whereas PyString_FromFormat has an independent
5335 implementation and uses "%zd" on all platforms for size_t values.
5336 This makes a difference on win64, where ``printf`` needs "%Id" to display

Nick Coghland2e09382008-09-11 12:11:06 +00005405- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00005406 return a list or None rather than a custom object.
5407
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005408- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005432 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5433 for catch_warnings() also led to an improvement in the raising of a
5434 DeprecationWarning related to warnings.warn_explicit().
5435
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005436- The deprecation warnings for the old camelCase threading API were removed.

5458
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005459- Issue #2975: When compiling several extension modules with Visual Studio 2008
5460 from the same python interpreter, some environment variables would grow
5461 without limit.
5462
Benjamin Peterson37346b22008-08-23 20:27:43 +00005463- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5464 exploitation of poor argument checking.
5465
Gerhard Häringef2276b2008-09-12 13:54:06 +00005466- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005500What's New in Python 2.6 beta 3?
5501================================
5502
Barry Warsaw07a4a382008-08-21 01:15:08 +00005503*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005504
5505Core and Builtins
5506-----------------
5507
Guido van Rossumf8402962008-08-20 15:01:50 +00005508- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5509 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5510 extensions do not automatically benefit from the class attribute
5511 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5512 to their tp_flags field if they care. This is a backwards
5513 compatibility feature; in 3.0, all types will use the cache by
5514 default.
5515
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005516- Keyword arguments can now follow starred arguments. (``f(a, *args,
5517 keyword=23)`` is now valid syntax.)
5518
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005519- ctypes function pointers that are COM methods have a boolean True
5520 value again.
5521
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005522- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5523 by denying s# to parse objects that have a releasebuffer procedure,
5524 and introducing s*.
5525
Georg Brandl1e13ea92008-08-11 09:07:59 +00005526- Issue #3537: Fix an assertion failure when an empty but presized dict
5527 object was stored in the freelist.
5528
Mark Dickinsonb6467572008-08-04 21:30:09 +00005529- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5530 ValueError consistently across platforms.
5531
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005532- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5533 (64bit Unix, for example), unichr() would truncate its argument and return
5534 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5535
Neal Norwitze7d8be82008-07-31 17:17:14 +00005536- Apply security patches from Apple.
5537
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005538- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5539 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5540
Antoine Pitrou92f82162008-07-25 22:22:08 +00005541- Issue #1819: function calls with several named parameters are now on
5542 average 35% faster (as measured by pybench).
5543
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005544- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5545 the python debugger steps into a class statement: the free variables (local
5546 variables defined in an outer scope) would be deleted from the outer scope.
5547
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005548- Issue #2620: Overflow checking when allocating or reallocating memory
5549 was not always being done properly in some python types and extension
5550 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5551 all been updated to perform better checks and places in the code that
5552 would previously leak memory on the error path when such an allocation
5553 failed have been fixed.
5554

5556-------
5557
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005558- Issue #3612: Added some missing basic types in ctypes.wintypes.
5559
Benjamin Petersone977ad42008-08-20 01:42:01 +00005560- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5561 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5562
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005563- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5564 version reported by these tools does not necessarily follow the python
5565 version numbering scheme, so the module is less strict when parsing it.
5566
Nick Coghlanf70385a2008-08-18 12:42:46 +00005567- Issue #2235: Added Py3k warnings for types which will become unhashable
5568 under the stricter __hash__ inheritance rules in 3.0. Several types
5569 which did not meet the rules for hash invariants and were already
5570 unhashable in 3.0 have now been explicitly flagged as unhashable in
5571 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5572 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5573
Brett Cannon88f801d2008-08-18 00:46:22 +00005574- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5582
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005583- Issue #3575: Incremental decoder's decode function now takes bytearray
5584 by using 's*' instead of 't#'.
5585
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005586- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005587 fails unicode conversion on 2nd parameter. (windows only)
5588
Georg Brandl222e2082010-08-01 22:27:39 +00005589- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005590 in a redirect.
5591
Brett Cannonabe423e2008-08-16 21:47:07 +00005592- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005593 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005594
Facundo Batistaeb90b782008-08-16 14:44:07 +00005595- Issue #2776: fixed small issue when handling an URL with double slash
5596 after a 302 response in the case of not going through a proxy.
5597
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005598- Issue #2676: in the email package, content-type parsing was hanging on
5599 pathological input because of quadratic or exponential behaviour of a
5600 regular expression.
5601
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005602- Issue #3476: binary buffered reading through the new "io" library is now
5603 thread-safe.
5604
Brett Cannonbf3157b2008-08-14 05:00:03 +00005605- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5606 since mimetools itself is deprecated. Because modules are cached, all
5607 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5608
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005609- Issue #3134: shutil referenced undefined WindowsError symbol.
5610
Robert Schuppenies14646332008-08-10 11:01:53 +00005611- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5612 menu entries were not deleted.
5613
Brett Cannon83e81842008-08-09 23:30:55 +00005614- Copied the implementation of reduce() to _functools.reduce() to have a
5615 version that did not raise a DeprecationWarning under -3.
5616
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005617- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5618 a MemoryError rather than silently stop the iteration.
5619
Guido van Rossum59ce9012008-08-09 14:55:34 +00005620- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5621 to _sre.compile() will now be rejected. This should not affect anybody
5622 since the re.compile() function never generates invalid re-bytecode.
5623
Skip Montanaroa032bf42008-08-08 22:52:51 +00005624- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5625 upon first access it can be automatically initialized from the csv file if
5626 it wasn't initialized during instantiation.
5627
Brett Cannon3aa2a492008-08-06 22:28:09 +00005628- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5629 the reload() built-in has been removed.
5630
Brett Cannon7e30b672008-08-04 21:52:25 +00005631- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005632 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005643 asking for a specific length. This problem only affected files opened
5644 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005645

5668
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005669- Issue #3394: zipfile.writestr sets external attributes when passed a
5670 file name rather than a ZipInfo instance, so files are extracted with
5671 mode 0600 rather than 000 under Unix.
5672
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005673- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5674 argument in python 2.5, this broke code that subclassed Popen to include its

5686 interaction with the tp_hash slot (added in 2.6b2) are now documented
5687
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005688- Issue #643841: The language reference now provides more detailed
5689 coverage of the lookup process for special methods. The disclaimers
5690 regarding lack of coverage of new-style classes have also been
5691 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005694What's New in Python 2.6 beta 2?
5695================================
5696
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005697*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005699Core and Builtins
5700-----------------
5701
Georg Brandl3e483f62008-07-16 22:57:41 +00005702- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5703 its methods now allow for items objects that can be converted to
5704 an integer using operator.index().
5705
Mark Dickinson64b7e502008-07-16 09:40:03 +00005706- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5707 produced a ValueError instead of giving the correct float.
5708
Eric Smitha5fa5a22008-07-16 00:11:49 +00005709- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5710 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5711
Mark Dickinson7103aa42008-07-15 19:08:33 +00005712- Issue #3008: the float type has a new instance method 'float.hex'
5713 and a new class method 'float.fromhex' to convert floating-point
5714 numbers to and from hexadecimal strings, respectively.
5715
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005716- Issue #2235: __hash__ is once again inherited by default. To allow
5717 collections.Hashable to remain meaningful in the presence of the
5718 default hash implementation (object.__hash__), it is now possible
5719 to explicit block inheritance of hash by setting __hash__=None at
5720 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5721 level.
5722
Nick Coghlanb028f502008-07-13 14:52:36 +00005723- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5724 the parent module cannot be found while performing an absolute import.
5725 This means that an incorrectly defined __package__ attribute will
5726 now only prevent relative imports in that module rather than causing
5727 all imports from that module to fail.
5728
Nick Coghlan14ff9942008-07-08 14:21:42 +00005729- Issue #2517: Allow unicode messages in Exceptions again by correctly
5730 bypassing the instance dictionary when looking up __unicode__ on
5731 new-style classes.
5732
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005733- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5734 set to a custom object whose write() method happens to install
5735 another file in sys.stdout.
5736
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005737- Issue #3088: Corrected a race condition in classes derived from
5738 threading.local: the first member set by a thread could be saved in
5739 another thread's dictionary.
5740
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005741- Issue #3004: Minor change to slice.indices(): the start and stop
5742 arguments are now treated identically, making the behaviour easier
5743 to describe and understand. For example, slice(None, -10,
5744 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5745 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5746 10, -1).
5747
Georg Brandl278fc502008-07-19 12:46:12 +00005748- Issue #3219: Calling a function with repeated keyword arguments,
5749 f(a=2, a=23), would not cause a syntax error. This was a regression
5750 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005751
Georg Brandl278fc502008-07-19 12:46:12 +00005752- Issue #2862: Make int and float freelist management consistent with
5753 other freelists. Changes their CompactFreeList apis into
5754 ClearFreeList apis and calls them via gc.collect().

5760 api functions without holding the GIL, which could lead to a fatal
5761 error when they failed.
5762
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005763- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5772 ForkingPickler.register() to resolve conflict with ctypes.
5773
Vinay Sajip51e65192008-07-18 09:01:10 +00005774- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005775
Thomas Heller880f5292008-07-15 19:39:38 +00005776- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5777 a valid dlerror() message.

5785
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005786- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005787
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005788- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5789 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005790 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005791 content-length. The problem had been corrected in the 2.4 branch, but never
5792 merged into trunk.
5793
Georg Brandle78fbcc2008-07-05 10:13:36 +00005794- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005805 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005806
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005807- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5808 handling is now the same as that of other special attributes like __name__).
5809
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005810- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5811 removal in Python 3.0 in favor of urllib2.urlopen().

6263 original Python code has been kept as backup). This will allow for
6264 using the 'warning's machinery in such places as the parser where
6265 use of pure Python code is not possible. Both the ``showarning()``
6266 and ``formatwarning()`` gain an optional 'line' argument which is
6267 not called by default for backwards-compatibility reasons. Setting
6268 ``warnings.showwarning()`` to an implementation that lacks support
6269 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006332- Issue #2550: The approach used by client/server code for obtaining
6333 ports to listen on in network-oriented tests has been refined in an
6334 effort to facilitate running multiple instances of the entire
6335 regression test suite in parallel without issue.
6336 test_support.bind_port() has been fixed such that it will always
6337 return a unique port -- which wasn't always the case with the
6338 previous implementation, especially if socket options had been set
6339 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6340 new implementation of bind_port() will actually raise an exception
6341 if it is passed an AF_INET/SOCK_STREAM socket with either the
6342 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6343 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6344 the socket it's been passed. This currently only applies to
6345 Windows. This option prevents any other sockets from binding to the
6346 host/port we've bound to, thus removing the possibility of the
6347 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6348 when a second SOCK_STREAM socket binds and accepts to a host/port
6349 that's already been bound by another socket. The optional preferred
6350 port parameter to bind_port() has been removed. Under no
6351 circumstances should tests be hard coding ports!
6352
6353 test_support.find_unused_port() has also been introduced, which will
6354 pass a temporary socket object to bind_port() in order to obtain an
6355 unused port. The temporary socket object is then closed and
6356 deleted, and the port is returned. This method should only be used
6357 for obtaining an unused port in order to pass to an external program
6358 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6359 a parameter to a server-oriented class that doesn't give you direct
6360 access to the underlying socket used.
6361
6362 Finally, test_support.HOST has been introduced, which should be used
6363 for the host argument of any relevant socket calls (i.e. bind and
6364 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006365
6366 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006367 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006368 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6369 test_asynchat and test_socket_ssl.
6370
Georg Brandl3ee81df2008-05-17 18:14:43 +00006371 It is now possible for multiple instances of the regression test
6372 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006651- Added the future_builtins module, which contains hex() and oct().
6652 These are the PEP 3127 version of these functions, designed to be
6653 compatible with the hex() and oct() builtins from Python 3.0. They
6654 differ slightly in their output formats from the existing, unchanged
6655 Python 2.6 builtins. The expected usage of the future_builtins
6656 module is:
6657 from future_builtins import hex, oct
6658
Eric Smith7ef40bf2008-02-20 23:34:22 +00006659- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6660 exponents for exponents with absolute value < 100. Follows C99
6661 standard. This is a change on Windows, which would use 3 digits.
6662 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6663 so that any alterations it does to the resulting string will be
6664 available in stringlib/formatter.h (for float.__format__).
6665
Eric Smith5a3c1352008-02-19 13:21:56 +00006666- Implemented PEP 3101, Advanced String Formatting. This adds a new
6667 builtin format(); a format() method for str and unicode; a
6668 __format__() method to object, str, unicode, int, long, float, and
6669 datetime; the class string.Formatter; and the C API
6670 PyObject_Format().
6671
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672- Fixed several potential crashes, all caused by specially crafted
6673 __del__ methods exploiting objects in temporarily inconsistent
6674 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006675
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006676- Issue #2115: Important speedup in setting __slot__ attributes. Also

Georg Brandl3ee81df2008-05-17 18:14:43 +00006683- Clear all free lists during a gc.collect() of the highest generation
6684 in order to allow pymalloc to free more arenas. Python may give back
6685 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006686
Georg Brandl3ee81df2008-05-17 18:14:43 +00006687- Issue #2045: Fix an infinite recursion triggered when printing a
6688 subclass of collections.defaultdict, if its default_factory is set
6689 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006690
Christian Heimesf75dbef2008-02-08 00:11:31 +00006691- Fixed a minor memory leak in dictobject.c. The content of the free
6692 list was not freed on interpreter shutdown.
6693
Georg Brandl21e99f42010-03-07 15:23:59 +00006694- Limit free list of method and built-in function objects to 256

6698 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006699 to compact the internal free lists of pre-allocted ints and floats.
6700
Georg Brandl3ee81df2008-05-17 18:14:43 +00006701- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6702 calls. Python expected the return type int but the fork familie
6703 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006717- Patch #1473257: generator objects gain a gi_code attribute. This is
6718 the same object as the func_code attribute of the function that
6719 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006720
Georg Brandl3ee81df2008-05-17 18:14:43 +00006721- Issue #1920: "while 0" statements were completely removed by the
6722 compiler, even in the presence of an "else" clause, which is
6723 supposed to be run when the condition is false. Now the compiler
6724 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006725
Guido van Rossumeead05f2008-01-24 18:21:02 +00006726- A few crashers fixed: weakref_in_del.py (issue #1377858);

6733
Georg Brandl3ee81df2008-05-17 18:14:43 +00006734- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006735 several extension methods and modules do not work without unicode
6736 support.
6737

6740
Georg Brandl14404b62008-01-19 19:27:05 +00006741- Issue #1679: "0x" was taken as a valid integer literal.
6742
Georg Brandl6caad7d2008-01-26 14:19:22 +00006743- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006744 added.
6745
Christian Heimesc94e2b52008-01-14 04:13:37 +00006746- sys.float_info / PyFloat_GetInfo: The floating point information
6747 object was converted from a dict to a specialized structseq object.
6748
Georg Brandl3ee81df2008-05-17 18:14:43 +00006749- Patch #1816: Added sys.flags structseq. It exposes the status of
6750 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006751
Georg Brandl3ee81df2008-05-17 18:14:43 +00006752- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006756- Patch #1700288: added a type attribute cache that caches method
6757 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006758
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006759- Bug #1776: __import__() no longer accepts filenames on any platform.
6760 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00006762- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6763
Georg Brandl3ee81df2008-05-17 18:14:43 +00006764- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6765 envvar and sys.dont_write_bytecode attribute. All these can be set
6766 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006767
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768- Improve some exception messages when Windows fails to load an
6769 extension module. Now we get for example '%1 is not a valid Win32
6770 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006777- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006778 and INF. float("nan"), float("inf") and float("-inf") now work on
6779 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006781- Compiler now generates simpler and faster code for dictionary
6782 literals. The oparg for BUILD_MAP now indicates an estimated
6783 dictionary size. There is a new opcode, STORE_MAP, for adding
6784 entries to the dictionary.

6796
Nick Coghlanef01d822007-12-03 12:55:17 +00006797- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00006813- Patch #1739468: Directories and zipfiles containing a __main__.py
6814 file can now be directly executed by passing their name to the
6815 interpreter. The directory/zipfile is automatically inserted as the
6816 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006817
Georg Brandl3ee81df2008-05-17 18:14:43 +00006818- Issue #1265: Fix a problem with sys.settrace, if the tracing
6819 function uses a generator expression when at the same time the
6820 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006821
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006822- sets and frozensets now have an isdisjoint() method.
6823
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006824- optimize the performance of builtin.sum().
6825

6827
Georg Brandl21e99f42010-03-07 15:23:59 +00006828- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006829 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6830 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006831
Georg Brandl3ee81df2008-05-17 18:14:43 +00006832- Issue #1686386: Tuple's tp_repr did not take into account the
6833 possibility of having a self-referential tuple, which is possible
6834 from C code. Nor did object's tp_str consider that a type's tp_str
6835 could do something that could lead to an inifinite recursion.
6836 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6837 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006838
Georg Brandl3ee81df2008-05-17 18:14:43 +00006839- Issue #1164: It was possible to trigger deadlock when using the
6840 'print' statement to write to a file since the GIL was not released
6841 as needed. Now PyObject_Print() does the right thing along with
6842 various tp_print implementations of the built-in types and those in
6843 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006844
Georg Brandl3ee81df2008-05-17 18:14:43 +00006845- Issue #1147: Exceptions were directly allowing string exceptions in
6846 their throw() method even though string exceptions no longer
6847 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Issue #1096: Prevent a segfault from getting the repr of a very
6850 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006851
Brett Cannon1e534b52007-09-07 04:18:30 +00006852- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006853 PyObject_Call() never calling back out to Python code to trigger
6854 recursion depth updates/checks. Required the creation of a static
6855 RuntimeError instance in case normalizing an exception put the
6856 recursion check value past its limit. Fixes crashers
6857 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006858
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006872- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006873 __*__ attributes. (Some already existed, e.g., __doc__ and
6874 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006875
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006876- Add -3 option to the interpreter to warn about features that are
6877 deprecated and will be changed/removed in Python 3.0.
6878
Georg Brandl2134e752007-05-21 20:34:16 +00006879- Patch #1686487: you can now pass any mapping after '**' in function
6880 calls.
6881
Collin Winter62903052007-05-18 23:11:24 +00006882- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006883 "except E as target:". This is to provide forwards compatibility
6884 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006885
Brett Cannon229cee22007-05-05 01:34:02 +00006886- Deprecate BaseException.message as per PEP 352.
6887
Georg Brandl3ee81df2008-05-17 18:14:43 +00006888- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006889 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006890
Vinay Sajip8549ce32007-05-06 17:53:37 +00006891- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006892 setting a plain string, ie don't expand to single letter identifiers.
6893
Raymond Hettinger13936692007-04-11 18:40:58 +00006894- Request #1191699: Slices can now be pickled.
6895
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006896- Request #1193128: str.translate() now allows a None argument for
6897 translations that only remove characters without re-mapping the
6898 remaining characters.
6899
Georg Brandl5cb76c12007-03-21 09:00:39 +00006900- Patch #1682205: a TypeError while unpacking an iterable is no longer
6901 masked by a generic one with the message "unpack non-sequence".
6902
Neal Norwitzaa754b72007-03-21 06:39:48 +00006903- Remove unused file Python/fmod.c.
6904
Guido van Rossum143b5642007-03-23 04:58:42 +00006905- Bug #1683368: The object.__init__() and object.__new__() methods are
6906 now stricter in rejecting excess arguments. The only time when
6907 either allows excess arguments is when it is not overridden and the
6908 other one is. For backwards compatibility, when both are
6909 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006910 warning later). Also, type.__init__() insists on the same signature
6911 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6914 object to complex using its __complex__() method before falling back
6915 to the __float__() method. Therefore, the functions in the cmath
6916 module now can operate on objects that define a __complex__()
6917 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006918
Georg Brandl3ee81df2008-05-17 18:14:43 +00006919- Patch #1623563: allow __class__ assignment for classes with
6920 __slots__. The old and the new class are still required to have the
6921 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006922
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923- Patch #1642547: Fix an error/crash when encountering syntax errors

6927 ``object.__reduce_ex__()`` is called with an object that is faking
6928 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006929
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930- Patch #1680015: Don't modify __slots__ tuple if it contains an

6934
Georg Brandl7b9c5552007-03-12 14:30:05 +00006935- Bug #1678647: write a newline after printing an exception in any
6936 case, even when converting the value to a string failed.
6937
Georg Brandl871f1bc2007-03-12 13:17:36 +00006938- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006939 its argument, if it exists. If not, it will work like before. This
6940 allows customizing the output of dir() in the presence of a
6941 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006942
Collin Winter276887b2007-03-12 16:11:39 +00006943- Patch #922167: Python no longer segfaults when faced with infinitely
6944 self-recursive reload() calls (as reported by bug #742342).
6945
Georg Brandl3ee81df2008-05-17 18:14:43 +00006946- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006949- Patch #1491866: change the complex() constructor to allow
6950 parthensized forms. This means complex(repr(x)) now works instead of
6951 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006952
Georg Brandlaa2321b2007-03-07 00:40:28 +00006953- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006954 makes the filenames the warning module prints much more sensible
6955 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006956
Georg Brandl49aafc92007-03-07 00:34:46 +00006957- Variant of patch #697613: don't exit the interpreter on a SystemExit
6958 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006959 variable is given, but break into the interactive interpreter just
6960 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006967
Georg Brandl0fca97a2007-03-05 22:28:08 +00006968- Patch #1674228: when assigning a slice (old-style), check for the
6969 sq_ass_slice instead of the sq_slice slot.
6970
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971- When printing an unraisable error, don't print exceptions. before
6972 the name. This duplicates the behavior whening normally printing
6973 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00006974
Georg Brandl3ee81df2008-05-17 18:14:43 +00006975- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00007506 AttributeError instead of an IOError when the server's response
7507 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007508

Georg Brandl3ee81df2008-05-17 18:14:43 +00007513- Patch #1429539: pdb now correctly initializes the __main__ module
7514 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007515 correctly now.
7516

7523
Georg Brandl3ee81df2008-05-17 18:14:43 +00007524- Patch #1530482: add pydoc.render_doc() which returns the

7539
Georg Brandl92a6bae2007-03-13 17:43:32 +00007540- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007541 are set for invalid interpolation sequences that would lead to
7542 errors on reading back those values.

7585 returned string up to the first NUL character.

7596
Georg Brandl3ee81df2008-05-17 18:14:43 +00007597- unittest now verifies more of its assumptions. In particular,
7598 TestCase and TestSuite subclasses (not instances) are no longer
7599 accepted in TestSuite.addTest(). This should cause no
7600 incompatibility since it never made sense with ordinary subclasses
7601 -- the failure just occurred later, with a more cumbersome
7602 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007889 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007990- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00007991 time so that opening a database previously created with the DB_DUP
7992 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7993 opens. Specifically: dictionary assignment to a DB object will
7994 replace all values for a given key when the database allows
7995 duplicate values. DB users should use DB.put(k, v) when they want
7996 to store duplicates; not DB[k] = v.

8005 behavior of quoting dots if they are the second character of any
8006 line.

8352 of w# format code incorrectly truncated the length to an int, even
8353 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8354 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008384- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8385 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
