126
Georg Brandlba83f822010-03-14 09:50:54 +0000127- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
128 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
129 argument's __int__ method to convert to an integer before packing. It also
130 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
131 was inconsistent: __int__ was used for some integer codes but not for others,
132 and the set of integer codes for which it was used differed between native
133 packing and standard packing.)

346 and add the additional members returned in an OSVERSIONINFOEX structure. The
347 new members are service_pack_major, service_pack_minor, suite_mask, and
348 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000403 file position when calling `truncate()`. It would previously change the file
404 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000405 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

410 class used to represent files stored inside an archive. The new
411 implementation is significantly faster and can be wrapped in a
412 ``io.BufferedReader`` object for more speedups. It also solves an issue
413 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
414 Patch by Nir Aides.

422 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000423
Georg Brandlba83f822010-03-14 09:50:54 +0000424- Issue #7748: Since unicode values are supported for some metadata options in
425 Distutils, the DistributionMetadata get_* methods will now return an utf-8
426 encoded string for them. This ensures that the upload and register commands
427 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000511 DeprecationWarning when passed a float argument where an integer was expected.
512 These functions and methods now raise TypeError instead. The majority of the
513 effects of this change are in the extension modules, but some core functions
514 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
515 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000698- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
699 decimal string that's guaranteed to round back to x under correct rounding
700 (with round-half-to-even rounding mode). Previously it gave a string based on
701 rounding x to 17 decimal digits. repr(x) for a complex number behaves
702 similarly. On platforms where the correctly-rounded strtod and dtoa code is
703 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000705- Issue #7117: On almost all platforms: float-to-string and string-to-float
706 conversions within Python are now correctly rounded. Places these conversions
707 occur include: str for floats and complex numbers; the float and complex
708 constructors; old-style and new-style numeric formatting; serialization and
709 deserialization of floats and complex numbers using marshal, pickle and json;
710 parsing of float and imaginary literals in Python code; Decimal-to-float
711 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000712
Georg Brandlba83f822010-03-14 09:50:54 +0000713 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
714 providing correctly-rounded strtod and dtoa C functions. This code is
715 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
716 the C compiler. There may be a small number of platforms on which correct
717 operation of this code cannot be guaranteed, so the code is not used: notably,
718 this applies to platforms where the C double format is not IEEE 754 binary64,
719 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
720 and Python's configure script is unable to determine how to change the FPU
721 precision. On these platforms conversions use the platform strtod and dtoa,
722 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000724- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
725 uses the correctly-rounded string <-> float conversions described above (when
726 available), and so produces correctly rounded results that will display nicely
727 under the float repr. There are two related small changes: (1) round now
728 accepts any class with an ``__index__()`` method for its second argument (but
729 no longer accepts floats for the second argument), and (2) an excessively
730 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
731 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000874 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
875 (2) parsing of strings representing infinities and nans was locale aware; and

Georg Brandlba83f822010-03-14 09:50:54 +0000878- Issue #5920: For ``float.__format__()``, change the behavior with the empty
879 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
880 but with at least one decimal point and with a default precision
881 of 12. Previously, the behavior the same but with a default precision of 6.
882 This more closely matches ``str()``, and reduces surprises when adding
883 alignment flags to the empty presentation type. This also affects the new
884 complex.__format__ in the same way.
885

1081
Georg Brandlba83f822010-03-14 09:50:54 +00001082- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1083 file objects with closefd=False. The file descriptor is still kept open but
1084 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001108- On windows, ``os.chdir()`` given unicode was not working if

1110 this code path is really executed because I cannot move to such directory on
1111 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001113- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1114 element is temporarily replaced with an equivalent frozenset. But the
1115 eventual KeyError would always report the empty ``frozenset()`` as the missing

1137 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1138 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1139 of using the replace error handler in PyUnicode_DecodeUTF8().

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001141- Issue #3739: The unicode-internal encoder now reports the number of characters

2513
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002514- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2515 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2516 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2517 ``printf`` function, whereas PyString_FromFormat has an independent
2518 implementation and uses "%zd" on all platforms for size_t values.
2519 This makes a difference on win64, where ``printf`` needs "%Id" to display
2520 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002522- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2526 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002537 was correctly parsed but parsing of subsequent arguments failed.
2538
Vinay Sajip35e3b032008-09-01 14:33:59 +00002539- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002540 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2541 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2542 when given a tuple of classes as second argument, were looking up
2543 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2544 type object.

2638
Jesse Noller438195f2009-01-18 21:04:36 +00002639- Issue #4301: Patch the logging module to add processName support, remove
2640 _check_logger_class from multiprocessing.
2641
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002642- Issue #2975: When compiling several extension modules with Visual Studio 2008
2643 from the same python interpreter, some environment variables would grow
2644 without limit.
2645
Benjamin Peterson37346b22008-08-23 20:27:43 +00002646- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2647 exploitation of poor argument checking.

2652 remaining ones have "pysqlite_" prefix.
2653
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002654- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2662 wrapper for warnings.catch_warnings() that makes it easier to check
2663 that expected warning messages are being reported.
2664
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002665- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002683What's New in Python 2.6 beta 3?
2684================================
2685
Barry Warsaw07a4a382008-08-21 01:15:08 +00002686*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002687
2688Core and Builtins
2689-----------------
2690
Guido van Rossumf8402962008-08-20 15:01:50 +00002691- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2692 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2693 extensions do not automatically benefit from the class attribute
2694 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2695 to their tp_flags field if they care. This is a backwards
2696 compatibility feature; in 3.0, all types will use the cache by
2697 default.
2698
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002699- Keyword arguments can now follow starred arguments. (``f(a, *args,
2700 keyword=23)`` is now valid syntax.)
2701
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002702- ctypes function pointers that are COM methods have a boolean True
2703 value again.
2704
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002705- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2706 by denying s# to parse objects that have a releasebuffer procedure,
2707 and introducing s*.
2708
Georg Brandl1e13ea92008-08-11 09:07:59 +00002709- Issue #3537: Fix an assertion failure when an empty but presized dict
2710 object was stored in the freelist.
2711
Mark Dickinsonb6467572008-08-04 21:30:09 +00002712- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2713 ValueError consistently across platforms.
2714
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002715- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2716 (64bit Unix, for example), unichr() would truncate its argument and return
2717 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2718
Neal Norwitze7d8be82008-07-31 17:17:14 +00002719- Apply security patches from Apple.
2720
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002721- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2722 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2723
Antoine Pitrou92f82162008-07-25 22:22:08 +00002724- Issue #1819: function calls with several named parameters are now on
2725 average 35% faster (as measured by pybench).
2726
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002727- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2728 the python debugger steps into a class statement: the free variables (local
2729 variables defined in an outer scope) would be deleted from the outer scope.
2730
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002731- Issue #2620: Overflow checking when allocating or reallocating memory
2732 was not always being done properly in some python types and extension
2733 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2734 all been updated to perform better checks and places in the code that
2735 would previously leak memory on the error path when such an allocation
2736 failed have been fixed.
2737
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002738Library
2739-------
2740
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002741- Issue #3612: Added some missing basic types in ctypes.wintypes.
2742
Benjamin Petersone977ad42008-08-20 01:42:01 +00002743- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2744 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2745
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002746- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2747 version reported by these tools does not necessarily follow the python
2748 version numbering scheme, so the module is less strict when parsing it.
2749
Nick Coghlanf70385a2008-08-18 12:42:46 +00002750- Issue #2235: Added Py3k warnings for types which will become unhashable
2751 under the stricter __hash__ inheritance rules in 3.0. Several types
2752 which did not meet the rules for hash invariants and were already
2753 unhashable in 3.0 have now been explicitly flagged as unhashable in
2754 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2755 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2756
Brett Cannon88f801d2008-08-18 00:46:22 +00002757- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2758 imported into the module but exposed as part of the module's API.
2759
Brett Cannon7b96f072008-08-18 00:41:11 +00002760- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2761
Brett Cannon46225e72008-08-18 00:36:52 +00002762- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2763
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002764- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2765
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002766- Issue #3575: Incremental decoder's decode function now takes bytearray
2767 by using 's*' instead of 't#'.
2768
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002769- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002770 fails unicode conversion on 2nd parameter. (windows only)
2771
Facundo Batista94f243a2008-08-17 03:38:39 +00002772- Issue 2464. urllib2 now supports a malformation in the URL received
2773 in a redirect.
2774
Brett Cannonabe423e2008-08-16 21:47:07 +00002775- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002776 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002777
Facundo Batistaeb90b782008-08-16 14:44:07 +00002778- Issue #2776: fixed small issue when handling an URL with double slash
2779 after a 302 response in the case of not going through a proxy.
2780
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002781- Issue #2676: in the email package, content-type parsing was hanging on
2782 pathological input because of quadratic or exponential behaviour of a
2783 regular expression.
2784
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002785- Issue #3476: binary buffered reading through the new "io" library is now
2786 thread-safe.
2787
Brett Cannonbf3157b2008-08-14 05:00:03 +00002788- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2789 since mimetools itself is deprecated. Because modules are cached, all
2790 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2791
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002792- Issue #3134: shutil referenced undefined WindowsError symbol.
2793
Robert Schuppenies14646332008-08-10 11:01:53 +00002794- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2795 menu entries were not deleted.
2796
Brett Cannon83e81842008-08-09 23:30:55 +00002797- Copied the implementation of reduce() to _functools.reduce() to have a
2798 version that did not raise a DeprecationWarning under -3.
2799
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002800- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2801 a MemoryError rather than silently stop the iteration.
2802
Guido van Rossum59ce9012008-08-09 14:55:34 +00002803- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2804 to _sre.compile() will now be rejected. This should not affect anybody
2805 since the re.compile() function never generates invalid re-bytecode.
2806
Skip Montanaroa032bf42008-08-08 22:52:51 +00002807- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2808 upon first access it can be automatically initialized from the csv file if
2809 it wasn't initialized during instantiation.
2810
Brett Cannon3aa2a492008-08-06 22:28:09 +00002811- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2812 the reload() built-in has been removed.
2813
Brett Cannon7e30b672008-08-04 21:52:25 +00002814- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002815 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2817 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2818 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2819 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2820 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002821
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002822- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2823 raised an AttributeError.
2824
Benjamin Peterson01a24322008-07-28 23:35:27 +00002825- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002826 asking for a specific length. This problem only affected files opened
2827 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002828
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002829- Issue #3449: Update decimal module to use most recent specification
2830 (v. 1.68) and tests (v. 2.58) from IBM.
2831
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002832- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2833

2838
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002839- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2840
2841- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2842 invalid arguments.
2843
2844- Issue #3302: Fix several crashes when calling locale's gettext functions
2845 with None arguments.
2846
2847- Issue #3389: Allow resolving dotted names for handlers in logging
2848 configuration files.
2849
2850- Deprecate the sunaudio module for removal in Python 3.0.
2851
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002852- Issue #3394: zipfile.writestr sets external attributes when passed a
2853 file name rather than a ZipInfo instance, so files are extracted with
2854 mode 0600 rather than 000 under Unix.
2855
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002856- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2857 argument in python 2.5, this broke code that subclassed Popen to include its
2858 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2866-------------
2867
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002868- Issue #2235: the C API function PyObject_HashNotImplemented and its
2869 interaction with the tp_hash slot (added in 2.6b2) are now documented
2870
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002871- Issue #643841: The language reference now provides more detailed
2872 coverage of the lookup process for special methods. The disclaimers
2873 regarding lack of coverage of new-style classes have also been
2874 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002877What's New in Python 2.6 beta 2?
2878================================
2879
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002880*Release date: 17-Jul-2008*
2881
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002882Core and Builtins
2883-----------------
2884
Georg Brandl3e483f62008-07-16 22:57:41 +00002885- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2886 its methods now allow for items objects that can be converted to
2887 an integer using operator.index().
2888
Mark Dickinson64b7e502008-07-16 09:40:03 +00002889- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2890 produced a ValueError instead of giving the correct float.
2891
Eric Smitha5fa5a22008-07-16 00:11:49 +00002892- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2893 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2894
Mark Dickinson7103aa42008-07-15 19:08:33 +00002895- Issue #3008: the float type has a new instance method 'float.hex'
2896 and a new class method 'float.fromhex' to convert floating-point
2897 numbers to and from hexadecimal strings, respectively.
2898
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002899- Issue #2235: __hash__ is once again inherited by default. To allow
2900 collections.Hashable to remain meaningful in the presence of the
2901 default hash implementation (object.__hash__), it is now possible
2902 to explicit block inheritance of hash by setting __hash__=None at
2903 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2904 level.
2905
Nick Coghlanb028f502008-07-13 14:52:36 +00002906- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2907 the parent module cannot be found while performing an absolute import.
2908 This means that an incorrectly defined __package__ attribute will
2909 now only prevent relative imports in that module rather than causing
2910 all imports from that module to fail.
2911
Nick Coghlan14ff9942008-07-08 14:21:42 +00002912- Issue #2517: Allow unicode messages in Exceptions again by correctly
2913 bypassing the instance dictionary when looking up __unicode__ on
2914 new-style classes.
2915
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002916- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2917 set to a custom object whose write() method happens to install
2918 another file in sys.stdout.
2919
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002920- Issue #3088: Corrected a race condition in classes derived from

2922 another thread's dictionary.
2923
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002924- Issue #3004: Minor change to slice.indices(): the start and stop
2925 arguments are now treated identically, making the behaviour easier
2926 to describe and understand. For example, slice(None, -10,
2927 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2928 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

3382 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003383 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003384
3385 This is controlled by the configure argument ``--with-universal-archs``:
3386
3387 - ``--with-universal-archs=all``: install 4-way universal
3388
3389 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3390
3391 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3392
3393 This option should be used in combination with ``--enable-universalsdk=``.

3432 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Issue #1631171: Re-implement the 'warnings' module in C (the
3446 original Python code has been kept as backup). This will allow for
3447 using the 'warning's machinery in such places as the parser where
3448 use of pure Python code is not possible. Both the ``showarning()``
3449 and ``formatwarning()`` gain an optional 'line' argument which is
3450 not called by default for backwards-compatibility reasons. Setting
3451 ``warnings.showwarning()`` to an implementation that lacks support
3452 for the ``line`` argument will raise a DeprecationWarning.

3476
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003477- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- Issue #2550: The approach used by client/server code for obtaining
3516 ports to listen on in network-oriented tests has been refined in an
3517 effort to facilitate running multiple instances of the entire
3518 regression test suite in parallel without issue.
3519 test_support.bind_port() has been fixed such that it will always
3520 return a unique port -- which wasn't always the case with the
3521 previous implementation, especially if socket options had been set
3522 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3523 new implementation of bind_port() will actually raise an exception
3524 if it is passed an AF_INET/SOCK_STREAM socket with either the
3525 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3526 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3527 the socket it's been passed. This currently only applies to
3528 Windows. This option prevents any other sockets from binding to the
3529 host/port we've bound to, thus removing the possibility of the
3530 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3531 when a second SOCK_STREAM socket binds and accepts to a host/port
3532 that's already been bound by another socket. The optional preferred
3533 port parameter to bind_port() has been removed. Under no
3534 circumstances should tests be hard coding ports!
3535
3536 test_support.find_unused_port() has also been introduced, which will
3537 pass a temporary socket object to bind_port() in order to obtain an
3538 unused port. The temporary socket object is then closed and
3539 deleted, and the port is returned. This method should only be used
3540 for obtaining an unused port in order to pass to an external program
3541 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3542 a parameter to a server-oriented class that doesn't give you direct
3543 access to the underlying socket used.
3544
3545 Finally, test_support.HOST has been introduced, which should be used
3546 for the host argument of any relevant socket calls (i.e. bind and
3547 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003548
3549 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003551 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3552 test_asynchat and test_socket_ssl.
3553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554 It is now possible for multiple instances of the regression test
3555 suite to run in parallel without issue.

3823
Fred Drakea8ee94b2008-03-01 02:45:07 +00003824- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003825 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003827- Issue #2067: file.__exit__() now calls subclasses' close() method.
3828
3829- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003830
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003831- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003832 issue 215555 for a discussion.
3833
Eric Smitha73fbe72008-02-23 03:09:44 +00003834- Added the future_builtins module, which contains hex() and oct().
3835 These are the PEP 3127 version of these functions, designed to be
3836 compatible with the hex() and oct() builtins from Python 3.0. They
3837 differ slightly in their output formats from the existing, unchanged
3838 Python 2.6 builtins. The expected usage of the future_builtins
3839 module is:
3840 from future_builtins import hex, oct
3841
Eric Smith7ef40bf2008-02-20 23:34:22 +00003842- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3843 exponents for exponents with absolute value < 100. Follows C99
3844 standard. This is a change on Windows, which would use 3 digits.
3845 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3846 so that any alterations it does to the resulting string will be
3847 available in stringlib/formatter.h (for float.__format__).
3848
Eric Smith5a3c1352008-02-19 13:21:56 +00003849- Implemented PEP 3101, Advanced String Formatting. This adds a new
3850 builtin format(); a format() method for str and unicode; a
3851 __format__() method to object, str, unicode, int, long, float, and
3852 datetime; the class string.Formatter; and the C API
3853 PyObject_Format().
3854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Fixed several potential crashes, all caused by specially crafted
3856 __del__ methods exploiting objects in temporarily inconsistent
3857 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003858
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003859- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860 prevent a possible crash: an Abstract Base Class would try to access
3861 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Fixed repr() and str() of complex numbers with infinity or nan as
3864 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Clear all free lists during a gc.collect() of the highest generation
3867 in order to allow pymalloc to free more arenas. Python may give back
3868 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Issue #2045: Fix an infinite recursion triggered when printing a
3871 subclass of collections.defaultdict, if its default_factory is set
3872 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003873
Christian Heimesf75dbef2008-02-08 00:11:31 +00003874- Fixed a minor memory leak in dictobject.c. The content of the free
3875 list was not freed on interpreter shutdown.
3876
Georg Brandl21e99f42010-03-07 15:23:59 +00003877- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003879
Georg Brandl3ee81df2008-05-17 18:14:43 +00003880- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3881 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003882 to compact the internal free lists of pre-allocted ints and floats.
3883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3885 calls. Python expected the return type int but the fork familie
3886 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003887
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3889 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003890
Georg Brandl3ee81df2008-05-17 18:14:43 +00003891- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3892 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3895 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3898 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003899
Georg Brandl3ee81df2008-05-17 18:14:43 +00003900- Patch #1473257: generator objects gain a gi_code attribute. This is
3901 the same object as the func_code attribute of the function that
3902 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003903
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904- Issue #1920: "while 0" statements were completely removed by the
3905 compiler, even in the presence of an "else" clause, which is
3906 supposed to be run when the condition is false. Now the compiler
3907 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003908
Guido van Rossumeead05f2008-01-24 18:21:02 +00003909- A few crashers fixed: weakref_in_del.py (issue #1377858);
3910 loosing_dict_ref.py (issue #1303614, test67.py);
3911 borrowed_ref_[34].py (not in tracker).
3912
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003913- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003914 suppressed while an extension is loaded by calling SetErrorMode in
3915 dynload_win.c. The error is still reported properly.
3916
Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003918 several extension methods and modules do not work without unicode
3919 support.
3920
Georg Brandl26543b12008-01-21 18:36:51 +00003921- Issue #1882: when compiling code from a string, encoding cookies in the
3922 second line of code were not always recognized correctly.
3923
Georg Brandl14404b62008-01-19 19:27:05 +00003924- Issue #1679: "0x" was taken as a valid integer literal.
3925
Georg Brandl6caad7d2008-01-26 14:19:22 +00003926- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003927 added.
3928
Christian Heimesc94e2b52008-01-14 04:13:37 +00003929- sys.float_info / PyFloat_GetInfo: The floating point information
3930 object was converted from a dict to a specialized structseq object.
3931
Georg Brandl3ee81df2008-05-17 18:14:43 +00003932- Patch #1816: Added sys.flags structseq. It exposes the status of
3933 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003934
Georg Brandl3ee81df2008-05-17 18:14:43 +00003935- Objects/structseq.c: Implemented new structseq representation. The
3936 patch makes structseqs (e.g. the return value of os.stat) more
3937 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003938
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939- Patch #1700288: added a type attribute cache that caches method

3948 envvar and sys.dont_write_bytecode attribute. All these can be set
3949 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003950
Georg Brandl3ee81df2008-05-17 18:14:43 +00003951- Improve some exception messages when Windows fails to load an
3952 extension module. Now we get for example '%1 is not a valid Win32
3953 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003960- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961 and INF. float("nan"), float("inf") and float("-inf") now work on
3962 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- Compiler now generates simpler and faster code for dictionary
3965 literals. The oparg for BUILD_MAP now indicates an estimated
3966 dictionary size. There is a new opcode, STORE_MAP, for adding
3967 entries to the dictionary.

3992
Georg Brandl3ee81df2008-05-17 18:14:43 +00003993- Issue #1460: The utf-7 incremental decoder did not accept truncated
3994 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003995
Georg Brandl3ee81df2008-05-17 18:14:43 +00003996- Patch #1739468: Directories and zipfiles containing a __main__.py
3997 file can now be directly executed by passing their name to the
3998 interpreter. The directory/zipfile is automatically inserted as the
3999 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Issue #1265: Fix a problem with sys.settrace, if the tracing
4002 function uses a generator expression when at the same time the
4003 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004004
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004005- sets and frozensets now have an isdisjoint() method.
4006

4008
Neal Norwitz44f326e2007-10-05 05:29:17 +00004009- Fix warnings found by the new version of the Coverity checker.
4010
Georg Brandl21e99f42010-03-07 15:23:59 +00004011- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004012 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4013 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004014
Georg Brandl3ee81df2008-05-17 18:14:43 +00004015- Issue #1686386: Tuple's tp_repr did not take into account the
4016 possibility of having a self-referential tuple, which is possible
4017 from C code. Nor did object's tp_str consider that a type's tp_str
4018 could do something that could lead to an inifinite recursion.
4019 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4020 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004021
Georg Brandl3ee81df2008-05-17 18:14:43 +00004022- Issue #1164: It was possible to trigger deadlock when using the
4023 'print' statement to write to a file since the GIL was not released
4024 as needed. Now PyObject_Print() does the right thing along with
4025 various tp_print implementations of the built-in types and those in
4026 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004027
Georg Brandl3ee81df2008-05-17 18:14:43 +00004028- Issue #1147: Exceptions were directly allowing string exceptions in
4029 their throw() method even though string exceptions no longer
4030 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004031
Georg Brandl3ee81df2008-05-17 18:14:43 +00004032- Issue #1096: Prevent a segfault from getting the repr of a very
4033 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004034
Brett Cannon1e534b52007-09-07 04:18:30 +00004035- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004036 PyObject_Call() never calling back out to Python code to trigger
4037 recursion depth updates/checks. Required the creation of a static
4038 RuntimeError instance in case normalizing an exception put the
4039 recursion check value past its limit. Fixes crashers
4040 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004041
Georg Brandl3ee81df2008-05-17 18:14:43 +00004042- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004055- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004056 __*__ attributes. (Some already existed, e.g., __doc__ and
4057 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004058
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004059- Add -3 option to the interpreter to warn about features that are
4060 deprecated and will be changed/removed in Python 3.0.
4061
Georg Brandl2134e752007-05-21 20:34:16 +00004062- Patch #1686487: you can now pass any mapping after '**' in function
4063 calls.
4064
Collin Winter62903052007-05-18 23:11:24 +00004065- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004066 "except E as target:". This is to provide forwards compatibility
4067 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004068
Brett Cannon229cee22007-05-05 01:34:02 +00004069- Deprecate BaseException.message as per PEP 352.
4070
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004072 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004073
Vinay Sajip8549ce32007-05-06 17:53:37 +00004074- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004075 setting a plain string, ie don't expand to single letter identifiers.
4076
Raymond Hettinger13936692007-04-11 18:40:58 +00004077- Request #1191699: Slices can now be pickled.
4078
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004079- Request #1193128: str.translate() now allows a None argument for
4080 translations that only remove characters without re-mapping the
4081 remaining characters.
4082
Georg Brandl5cb76c12007-03-21 09:00:39 +00004083- Patch #1682205: a TypeError while unpacking an iterable is no longer
4084 masked by a generic one with the message "unpack non-sequence".
4085
Neal Norwitzaa754b72007-03-21 06:39:48 +00004086- Remove unused file Python/fmod.c.
4087
Guido van Rossum143b5642007-03-23 04:58:42 +00004088- Bug #1683368: The object.__init__() and object.__new__() methods are
4089 now stricter in rejecting excess arguments. The only time when
4090 either allows excess arguments is when it is not overridden and the
4091 other one is. For backwards compatibility, when both are
4092 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004093 warning later). Also, type.__init__() insists on the same signature
4094 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004095
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4097 object to complex using its __complex__() method before falling back
4098 to the __float__() method. Therefore, the functions in the cmath
4099 module now can operate on objects that define a __complex__()
4100 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Patch #1623563: allow __class__ assignment for classes with
4103 __slots__. The old and the new class are still required to have the
4104 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004109- Patch #1462488: Python no longer segfaults when
4110 ``object.__reduce_ex__()`` is called with an object that is faking
4111 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004112
Georg Brandl3ee81df2008-05-17 18:14:43 +00004113- Patch #1680015: Don't modify __slots__ tuple if it contains an

4117
Georg Brandl7b9c5552007-03-12 14:30:05 +00004118- Bug #1678647: write a newline after printing an exception in any
4119 case, even when converting the value to a string failed.
4120
Georg Brandl871f1bc2007-03-12 13:17:36 +00004121- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004122 its argument, if it exists. If not, it will work like before. This
4123 allows customizing the output of dir() in the presence of a
4124 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004125
Collin Winter276887b2007-03-12 16:11:39 +00004126- Patch #922167: Python no longer segfaults when faced with infinitely
4127 self-recursive reload() calls (as reported by bug #742342).
4128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Patch #1675981: remove unreachable code from ``type.__new__()``
4130 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Patch #1491866: change the complex() constructor to allow
4133 parthensized forms. This means complex(repr(x)) now works instead of
4134 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004135
Georg Brandlaa2321b2007-03-07 00:40:28 +00004136- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137 makes the filenames the warning module prints much more sensible
4138 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004139
Georg Brandl49aafc92007-03-07 00:34:46 +00004140- Variant of patch #697613: don't exit the interpreter on a SystemExit
4141 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142 variable is given, but break into the interactive interpreter just
4143 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Bug #1674503: close the file opened by execfile() in an error
4149 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004150
Georg Brandl0fca97a2007-03-05 22:28:08 +00004151- Patch #1674228: when assigning a slice (old-style), check for the
4152 sq_ass_slice instead of the sq_slice slot.
4153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- When printing an unraisable error, don't print exceptions. before
4155 the name. This duplicates the behavior whening normally printing
4156 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Bug #1653736: Properly discard third argument to

4165 created a weakref on itself during a __del__ call for new-style
4166 classes (classic classes still have the bug).

4213
Armin Rigo7ccbca92006-10-04 12:17:45 +00004214- A number of places, including integer negation and absolute value,

4722
Georg Brandl92a6bae2007-03-13 17:43:32 +00004723- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004724 are set for invalid interpolation sequences that would lead to

4781 TestCase and TestSuite subclasses (not instances) are no longer
4782 accepted in TestSuite.addTest(). This should cause no
4783 incompatibility since it never made sense with ordinary subclasses
4784 -- the failure just occurred later, with a more cumbersome
4785 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5067 with RFC 3207 and forgets any knowledge obtained from the server not
5068 obtained from the TLS negotiation itself. Patch contributed by Bill
5069 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005070
Georg Brandl3ee81df2008-05-17 18:14:43 +00005071- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005072 that the SMTP.starttls() caller no longer needs to call ehlo()
5073 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005074 does not claim to support starttls. Adds the
5075 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005130- itertools.chain() now has an alternate constructor,

5156 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5157 silently miscode subclasses of those types. Now, it raises a
5158 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005159

Georg Brandl3ee81df2008-05-17 18:14:43 +00005174 time so that opening a database previously created with the DB_DUP
5175 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5176 opens. Specifically: dictionary assignment to a DB object will
5177 replace all values for a given key when the database allows
5178 duplicate values. DB users should use DB.put(k, v) when they want
5179 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005180

5186 characters with ASCII value less than 32. Also, it correctly quotes
5187 dots only if they occur on a single line, as opposed to the previous
5188 behavior of quoting dots if they are the second character of any
5189 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005190

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005458- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459 periodic threadstate and signal checking in tight loops. By
5460 default, this option is turned-off. It should only be enabled in
5461 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5520 to ``PyTuple_SetItem``, it can be used to populate a brand new

5533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5535 of w# format code incorrectly truncated the length to an int, even
5536 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5537 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005538
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5561 outside of pystate.c and should not be necessary.
5562
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00005567- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5568 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005569
Georg Brandl3ee81df2008-05-17 18:14:43 +00005570- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5580 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005581

Georg Brandl3ee81df2008-05-17 18:14:43 +00005595- Removed the macfs module. It had been deprecated since Python 2.5.
5596 This lead to the deprecation of macostools.touched() as it relied
5597 solely on macfs and was a no-op under OS X.
