106 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
107 argument's __int__ method to convert to an integer before packing. It also
108 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
109 was inconsistent: __int__ was used for some integer codes but not for others,
110 and the set of integer codes for which it was used differed between native
111 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000371- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000372 file position when calling `truncate()`. It would previously change the file
373 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000374 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

377
Georg Brandlba83f822010-03-14 09:50:54 +0000378- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
379 class used to represent files stored inside an archive. The new
380 implementation is significantly faster and can be wrapped in a
381 ``io.BufferedReader`` object for more speedups. It also solves an issue
382 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
383 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +0000393- Issue #7748: Since unicode values are supported for some metadata options in
394 Distutils, the DistributionMetadata get_* methods will now return an utf-8
395 encoded string for them. This ensures that the upload and register commands
396 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000473- The ``__complex__()`` method is now looked up on the class of instances to
474 make it consistent with other special methods.

478
Mark Dickinson1b34d252010-01-01 17:27:30 +0000479- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000480 DeprecationWarning when passed a float argument where an integer was expected.
481 These functions and methods now raise TypeError instead. The majority of the
482 effects of this change are in the extension modules, but some core functions
483 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
484 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000667- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
668 decimal string that's guaranteed to round back to x under correct rounding
669 (with round-half-to-even rounding mode). Previously it gave a string based on
670 rounding x to 17 decimal digits. repr(x) for a complex number behaves
671 similarly. On platforms where the correctly-rounded strtod and dtoa code is
672 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000673
Georg Brandlba83f822010-03-14 09:50:54 +0000674- Issue #7117: On almost all platforms: float-to-string and string-to-float
675 conversions within Python are now correctly rounded. Places these conversions
676 occur include: str for floats and complex numbers; the float and complex
677 constructors; old-style and new-style numeric formatting; serialization and
678 deserialization of floats and complex numbers using marshal, pickle and json;
679 parsing of float and imaginary literals in Python code; Decimal-to-float
680 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000681
Georg Brandlba83f822010-03-14 09:50:54 +0000682 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
683 providing correctly-rounded strtod and dtoa C functions. This code is
684 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
685 the C compiler. There may be a small number of platforms on which correct
686 operation of this code cannot be guaranteed, so the code is not used: notably,
687 this applies to platforms where the C double format is not IEEE 754 binary64,
688 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
689 and Python's configure script is unable to determine how to change the FPU
690 precision. On these platforms conversions use the platform strtod and dtoa,
691 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000692
Georg Brandlba83f822010-03-14 09:50:54 +0000693- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
694 uses the correctly-rounded string <-> float conversions described above (when
695 available), and so produces correctly rounded results that will display nicely
696 under the float repr. There are two related small changes: (1) round now
697 accepts any class with an ``__index__()`` method for its second argument (but
698 no longer accepts floats for the second argument), and (2) an excessively
699 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
700 raises an exception.

849 but with at least one decimal point and with a default precision
850 of 12. Previously, the behavior the same but with a default precision of 6.
851 This more closely matches ``str()``, and reduces surprises when adding
852 alignment flags to the empty presentation type. This also affects the new
853 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +0000993- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
994 existing .py counterpart, override the co_filename attributes of all code

1050
Georg Brandlba83f822010-03-14 09:50:54 +00001051- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1052 file objects with closefd=False. The file descriptor is still kept open but
1053 the file object behaves like a closed file. The ``FileIO`` object also got a
1054 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001074- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001077- On windows, ``os.chdir()`` given unicode was not working if

1079 this code path is really executed because I cannot move to such directory on
1080 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001082- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1083 element is temporarily replaced with an equivalent frozenset. But the
1084 eventual KeyError would always report the empty ``frozenset()`` as the missing
1085 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001105- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1106 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1107 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1108 of using the replace error handler in PyUnicode_DecodeUTF8().
1109
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001110- Issue #3739: The unicode-internal encoder now reports the number of characters

1112
Georg Brandlba83f822010-03-14 09:50:54 +00001113- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1115 gives improved memory leak detection when running under Valgrind, while taking
1116 advantage of pymalloc at other times.

2347 __all__ attribute, rather than using a hardcoded and incomplete list.
2348
R. David Murray14dcd432009-10-14 13:58:07 +00002349- Issue #7058: Added save/restore for things like sys.argv and cwd to
2350 runtest_inner in regrtest, with warnings if the called test modifies them,
2351 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002358- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2359 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002360 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2361 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00002363- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2364 regression tests in parallel, shortening the total runtime.
2365
Georg Brandlba83f822010-03-14 09:50:54 +00002366- Issue #5354: New test support function import_fresh_module() makes it easy to
2367 import both normal and optimised versions of modules. test_heapq and
2368 test_warnings have been adjusted to use it, tests for other modules with both
2369 C and Python implementations in the stdlib can be adjusted to use it over
2370 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002378- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2379 should cause a test to be skipped are now done using import_module from test
2380 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002481- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2482
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002483- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2484 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2485 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2486 ``printf`` function, whereas PyString_FromFormat has an independent
2487 implementation and uses "%zd" on all platforms for size_t values.
2488 This makes a difference on win64, where ``printf`` needs "%Id" to display
2489 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002491- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2495 object; previously an int would be returned for small values. the __long__
2496 method is allowed to return either an int or a long, but the behaviour of
2497 float objects should not change to respect backward compatibility.
2498
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002499- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002505 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002506 was correctly parsed but parsing of subsequent arguments failed.
2507
Vinay Sajip35e3b032008-09-01 14:33:59 +00002508- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002509 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2510 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2511 when given a tuple of classes as second argument, were looking up
2512 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2513 type object.
2514
Neal Norwitz18aa3882008-08-24 05:04:52 +00002515- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00002641- Issue #3833: Use a different upgrade code for Win64 installers.
2642
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00002643- Issue #2271: Set SecureCustomProperties so that installation will properly
2644 use the TARGETDIR even for unprivileged users.
2645
Martin v. Löwis67543a92008-09-08 12:02:45 +00002646- Allow passing the MSI file name to merge.py.
2647
Vinay Sajip844f7412008-09-09 13:42:08 +00002648- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002649 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002652What's New in Python 2.6 beta 3?
2653================================
2654
Barry Warsaw07a4a382008-08-21 01:15:08 +00002655*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002656
2657Core and Builtins
2658-----------------
2659
Guido van Rossumf8402962008-08-20 15:01:50 +00002660- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2661 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2662 extensions do not automatically benefit from the class attribute
2663 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2664 to their tp_flags field if they care. This is a backwards
2665 compatibility feature; in 3.0, all types will use the cache by
2666 default.
2667
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002668- Keyword arguments can now follow starred arguments. (``f(a, *args,
2669 keyword=23)`` is now valid syntax.)
2670
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002671- ctypes function pointers that are COM methods have a boolean True
2672 value again.
2673
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002674- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2675 by denying s# to parse objects that have a releasebuffer procedure,
2676 and introducing s*.
2677
Georg Brandl1e13ea92008-08-11 09:07:59 +00002678- Issue #3537: Fix an assertion failure when an empty but presized dict
2679 object was stored in the freelist.
2680
Mark Dickinsonb6467572008-08-04 21:30:09 +00002681- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2682 ValueError consistently across platforms.
2683
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002684- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2685 (64bit Unix, for example), unichr() would truncate its argument and return
2686 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2687
Neal Norwitze7d8be82008-07-31 17:17:14 +00002688- Apply security patches from Apple.
2689
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002690- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2691 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2692
Antoine Pitrou92f82162008-07-25 22:22:08 +00002693- Issue #1819: function calls with several named parameters are now on
2694 average 35% faster (as measured by pybench).
2695
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002696- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2697 the python debugger steps into a class statement: the free variables (local
2698 variables defined in an outer scope) would be deleted from the outer scope.
2699
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002700- Issue #2620: Overflow checking when allocating or reallocating memory
2701 was not always being done properly in some python types and extension
2702 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2703 all been updated to perform better checks and places in the code that
2704 would previously leak memory on the error path when such an allocation
2705 failed have been fixed.
2706
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002707Library
2708-------
2709
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002710- Issue #3612: Added some missing basic types in ctypes.wintypes.
2711
Benjamin Petersone977ad42008-08-20 01:42:01 +00002712- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2713 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2714
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002715- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2716 version reported by these tools does not necessarily follow the python
2717 version numbering scheme, so the module is less strict when parsing it.
2718
Nick Coghlanf70385a2008-08-18 12:42:46 +00002719- Issue #2235: Added Py3k warnings for types which will become unhashable
2720 under the stricter __hash__ inheritance rules in 3.0. Several types
2721 which did not meet the rules for hash invariants and were already
2722 unhashable in 3.0 have now been explicitly flagged as unhashable in
2723 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2724 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2725
Brett Cannon88f801d2008-08-18 00:46:22 +00002726- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2727 imported into the module but exposed as part of the module's API.
2728
Brett Cannon7b96f072008-08-18 00:41:11 +00002729- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2730
Brett Cannon46225e72008-08-18 00:36:52 +00002731- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2732
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002733- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2734
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002735- Issue #3575: Incremental decoder's decode function now takes bytearray
2736 by using 's*' instead of 't#'.
2737
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002738- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002739 fails unicode conversion on 2nd parameter. (windows only)
2740
Facundo Batista94f243a2008-08-17 03:38:39 +00002741- Issue 2464. urllib2 now supports a malformation in the URL received
2742 in a redirect.
2743
Brett Cannonabe423e2008-08-16 21:47:07 +00002744- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002745 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002746
Facundo Batistaeb90b782008-08-16 14:44:07 +00002747- Issue #2776: fixed small issue when handling an URL with double slash
2748 after a 302 response in the case of not going through a proxy.
2749
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002750- Issue #2676: in the email package, content-type parsing was hanging on
2751 pathological input because of quadratic or exponential behaviour of a
2752 regular expression.
2753
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002754- Issue #3476: binary buffered reading through the new "io" library is now
2755 thread-safe.
2756
Brett Cannonbf3157b2008-08-14 05:00:03 +00002757- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2758 since mimetools itself is deprecated. Because modules are cached, all
2759 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2760
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002761- Issue #3134: shutil referenced undefined WindowsError symbol.
2762
Robert Schuppenies14646332008-08-10 11:01:53 +00002763- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2764 menu entries were not deleted.
2765
Brett Cannon83e81842008-08-09 23:30:55 +00002766- Copied the implementation of reduce() to _functools.reduce() to have a
2767 version that did not raise a DeprecationWarning under -3.
2768
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002769- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2770 a MemoryError rather than silently stop the iteration.
2771
Guido van Rossum59ce9012008-08-09 14:55:34 +00002772- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2773 to _sre.compile() will now be rejected. This should not affect anybody
2774 since the re.compile() function never generates invalid re-bytecode.
2775
Skip Montanaroa032bf42008-08-08 22:52:51 +00002776- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2777 upon first access it can be automatically initialized from the csv file if
2778 it wasn't initialized during instantiation.
2779
Brett Cannon3aa2a492008-08-06 22:28:09 +00002780- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2781 the reload() built-in has been removed.
2782
Brett Cannon7e30b672008-08-04 21:52:25 +00002783- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002784 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002785 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2786 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2787 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2788 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2789 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002790
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002791- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2792 raised an AttributeError.
2793
Benjamin Peterson01a24322008-07-28 23:35:27 +00002794- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002795 asking for a specific length. This problem only affected files opened
2796 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002797
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002798- Issue #3449: Update decimal module to use most recent specification
2799 (v. 1.68) and tests (v. 2.58) from IBM.
2800
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002801- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2809
2810- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2811 invalid arguments.
2812
2813- Issue #3302: Fix several crashes when calling locale's gettext functions
2814 with None arguments.
2815
2816- Issue #3389: Allow resolving dotted names for handlers in logging
2817 configuration files.
2818
2819- Deprecate the sunaudio module for removal in Python 3.0.
2820
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002821- Issue #3394: zipfile.writestr sets external attributes when passed a
2822 file name rather than a ZipInfo instance, so files are extracted with
2823 mode 0600 rather than 000 under Unix.
2824
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002825- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2826 argument in python 2.5, this broke code that subclassed Popen to include its
2827 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2835-------------
2836
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002837- Issue #2235: the C API function PyObject_HashNotImplemented and its
2838 interaction with the tp_hash slot (added in 2.6b2) are now documented
2839
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002840- Issue #643841: The language reference now provides more detailed
2841 coverage of the lookup process for special methods. The disclaimers
2842 regarding lack of coverage of new-style classes have also been
2843 removed, since the coverage is now fairly reasonable.

2848
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002849*Release date: 17-Jul-2008*

2852-----------------
2853
Georg Brandl3e483f62008-07-16 22:57:41 +00002854- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2855 its methods now allow for items objects that can be converted to
2856 an integer using operator.index().
2857
Mark Dickinson64b7e502008-07-16 09:40:03 +00002858- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2859 produced a ValueError instead of giving the correct float.
2860
Eric Smitha5fa5a22008-07-16 00:11:49 +00002861- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2862 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2863
Mark Dickinson7103aa42008-07-15 19:08:33 +00002864- Issue #3008: the float type has a new instance method 'float.hex'
2865 and a new class method 'float.fromhex' to convert floating-point
2866 numbers to and from hexadecimal strings, respectively.
2867
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002868- Issue #2235: __hash__ is once again inherited by default. To allow
2869 collections.Hashable to remain meaningful in the presence of the
2870 default hash implementation (object.__hash__), it is now possible
2871 to explicit block inheritance of hash by setting __hash__=None at
2872 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2873 level.
2874
Nick Coghlanb028f502008-07-13 14:52:36 +00002875- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2876 the parent module cannot be found while performing an absolute import.
2877 This means that an incorrectly defined __package__ attribute will
2878 now only prevent relative imports in that module rather than causing
2879 all imports from that module to fail.
2880
Nick Coghlan14ff9942008-07-08 14:21:42 +00002881- Issue #2517: Allow unicode messages in Exceptions again by correctly
2882 bypassing the instance dictionary when looking up __unicode__ on
2883 new-style classes.
2884
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002885- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2886 set to a custom object whose write() method happens to install
2887 another file in sys.stdout.
2888
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002889- Issue #3088: Corrected a race condition in classes derived from
2890 threading.local: the first member set by a thread could be saved in
2891 another thread's dictionary.
2892
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002893- Issue #3004: Minor change to slice.indices(): the start and stop
2894 arguments are now treated identically, making the behaviour easier
2895 to describe and understand. For example, slice(None, -10,
2896 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2897 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2898 10, -1).
2899
Georg Brandl278fc502008-07-19 12:46:12 +00002900- Issue #3219: Calling a function with repeated keyword arguments,
2901 f(a=2, a=23), would not cause a syntax error. This was a regression
2902 from 2.4 caused by the switch to the new compiler.

2912 api functions without holding the GIL, which could lead to a fatal
2913 error when they failed.
2914
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002915- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3349
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003350- On MacOS X it is now possible to install the framework in 64-bit
3351 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003352 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003353
3354 This is controlled by the configure argument ``--with-universal-archs``:
3355
3356 - ``--with-universal-archs=all``: install 4-way universal
3357
3358 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3359
3360 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3361
3362 This option should be used in combination with ``--enable-universalsdk=``.
3363
3364 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003400- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
3401 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003402
Christian Heimese74c8f22008-04-19 02:23:57 +00003403- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3404

3406 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003407

Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Issue #1631171: Re-implement the 'warnings' module in C (the
3415 original Python code has been kept as backup). This will allow for
3416 using the 'warning's machinery in such places as the parser where
3417 use of pure Python code is not possible. Both the ``showarning()``
3418 and ``formatwarning()`` gain an optional 'line' argument which is
3419 not called by default for backwards-compatibility reasons. Setting
3420 ``warnings.showwarning()`` to an implementation that lacks support
3421 for the ``line`` argument will raise a DeprecationWarning.

3445
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003446- The getpass module has been improved on Unix. It now uses /dev/tty
3447 by default and uses stderr instead of stdout. A GetPassWarning is
3448 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003449

Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003464 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Issue #2550: The approach used by client/server code for obtaining
3485 ports to listen on in network-oriented tests has been refined in an
3486 effort to facilitate running multiple instances of the entire
3487 regression test suite in parallel without issue.
3488 test_support.bind_port() has been fixed such that it will always
3489 return a unique port -- which wasn't always the case with the
3490 previous implementation, especially if socket options had been set
3491 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3492 new implementation of bind_port() will actually raise an exception
3493 if it is passed an AF_INET/SOCK_STREAM socket with either the
3494 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3495 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3496 the socket it's been passed. This currently only applies to
3497 Windows. This option prevents any other sockets from binding to the
3498 host/port we've bound to, thus removing the possibility of the
3499 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3500 when a second SOCK_STREAM socket binds and accepts to a host/port
3501 that's already been bound by another socket. The optional preferred
3502 port parameter to bind_port() has been removed. Under no
3503 circumstances should tests be hard coding ports!
3504
3505 test_support.find_unused_port() has also been introduced, which will
3506 pass a temporary socket object to bind_port() in order to obtain an
3507 unused port. The temporary socket object is then closed and
3508 deleted, and the port is returned. This method should only be used
3509 for obtaining an unused port in order to pass to an external program
3510 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3511 a parameter to a server-oriented class that doesn't give you direct
3512 access to the underlying socket used.
3513
3514 Finally, test_support.HOST has been introduced, which should be used
3515 for the host argument of any relevant socket calls (i.e. bind and
3516 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003517
3518 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003519 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003520 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3521 test_asynchat and test_socket_ssl.
3522
Georg Brandl3ee81df2008-05-17 18:14:43 +00003523 It is now possible for multiple instances of the regression test
3524 suite to run in parallel without issue.

3791-----------------
3792
Fred Drakea8ee94b2008-03-01 02:45:07 +00003793- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003794 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003795
Georg Brandlad61bc82008-02-23 15:11:18 +00003796- Issue #2067: file.__exit__() now calls subclasses' close() method.
3797
3798- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003799
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003800- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003801 issue 215555 for a discussion.
3802
Eric Smitha73fbe72008-02-23 03:09:44 +00003803- Added the future_builtins module, which contains hex() and oct().
3804 These are the PEP 3127 version of these functions, designed to be
3805 compatible with the hex() and oct() builtins from Python 3.0. They
3806 differ slightly in their output formats from the existing, unchanged
3807 Python 2.6 builtins. The expected usage of the future_builtins
3808 module is:
3809 from future_builtins import hex, oct
3810
Eric Smith7ef40bf2008-02-20 23:34:22 +00003811- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3812 exponents for exponents with absolute value < 100. Follows C99
3813 standard. This is a change on Windows, which would use 3 digits.
3814 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3815 so that any alterations it does to the resulting string will be
3816 available in stringlib/formatter.h (for float.__format__).
3817
Eric Smith5a3c1352008-02-19 13:21:56 +00003818- Implemented PEP 3101, Advanced String Formatting. This adds a new
3819 builtin format(); a format() method for str and unicode; a
3820 __format__() method to object, str, unicode, int, long, float, and
3821 datetime; the class string.Formatter; and the C API
3822 PyObject_Format().
3823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Fixed several potential crashes, all caused by specially crafted
3825 __del__ methods exploiting objects in temporarily inconsistent
3826 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003827
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003828- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003829 prevent a possible crash: an Abstract Base Class would try to access
3830 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Fixed repr() and str() of complex numbers with infinity or nan as
3833 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003834
Georg Brandl3ee81df2008-05-17 18:14:43 +00003835- Clear all free lists during a gc.collect() of the highest generation
3836 in order to allow pymalloc to free more arenas. Python may give back
3837 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003838
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839- Issue #2045: Fix an infinite recursion triggered when printing a
3840 subclass of collections.defaultdict, if its default_factory is set
3841 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003842
Christian Heimesf75dbef2008-02-08 00:11:31 +00003843- Fixed a minor memory leak in dictobject.c. The content of the free
3844 list was not freed on interpreter shutdown.
3845
Georg Brandl21e99f42010-03-07 15:23:59 +00003846- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3850 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003851 to compact the internal free lists of pre-allocted ints and floats.
3852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3854 calls. Python expected the return type int but the fork familie
3855 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3858 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3861 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3864 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3867 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003868
Georg Brandl3ee81df2008-05-17 18:14:43 +00003869- Patch #1473257: generator objects gain a gi_code attribute. This is
3870 the same object as the func_code attribute of the function that
3871 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Issue #1920: "while 0" statements were completely removed by the
3874 compiler, even in the presence of an "else" clause, which is
3875 supposed to be run when the condition is false. Now the compiler
3876 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003877
Guido van Rossumeead05f2008-01-24 18:21:02 +00003878- A few crashers fixed: weakref_in_del.py (issue #1377858);
3879 loosing_dict_ref.py (issue #1303614, test67.py);
3880 borrowed_ref_[34].py (not in tracker).
3881
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003882- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003883 suppressed while an extension is loaded by calling SetErrorMode in
3884 dynload_win.c. The error is still reported properly.
3885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003887 several extension methods and modules do not work without unicode
3888 support.
3889
Georg Brandl26543b12008-01-21 18:36:51 +00003890- Issue #1882: when compiling code from a string, encoding cookies in the
3891 second line of code were not always recognized correctly.
3892
Georg Brandl14404b62008-01-19 19:27:05 +00003893- Issue #1679: "0x" was taken as a valid integer literal.
3894
Georg Brandl6caad7d2008-01-26 14:19:22 +00003895- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003896 added.
3897
Christian Heimesc94e2b52008-01-14 04:13:37 +00003898- sys.float_info / PyFloat_GetInfo: The floating point information
3899 object was converted from a dict to a specialized structseq object.
3900
Georg Brandl3ee81df2008-05-17 18:14:43 +00003901- Patch #1816: Added sys.flags structseq. It exposes the status of
3902 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003903
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904- Objects/structseq.c: Implemented new structseq representation. The
3905 patch makes structseqs (e.g. the return value of os.stat) more
3906 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003907
Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Patch #1700288: added a type attribute cache that caches method
3909 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003910
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003911- Bug #1776: __import__() no longer accepts filenames on any platform.

3915
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3917 envvar and sys.dont_write_bytecode attribute. All these can be set
3918 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Improve some exception messages when Windows fails to load an
3921 extension module. Now we get for example '%1 is not a valid Win32
3922 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003923

3927 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003928
Christian Heimes0a8143f2007-12-18 23:22:54 +00003929- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003930 and INF. float("nan"), float("inf") and float("-inf") now work on
3931 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003932
Georg Brandl3ee81df2008-05-17 18:14:43 +00003933- Compiler now generates simpler and faster code for dictionary
3934 literals. The oparg for BUILD_MAP now indicates an estimated
3935 dictionary size. There is a new opcode, STORE_MAP, for adding
3936 entries to the dictionary.

3968 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003969
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970- Issue #1265: Fix a problem with sys.settrace, if the tracing
3971 function uses a generator expression when at the same time the
3972 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003973
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003974- sets and frozensets now have an isdisjoint() method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003981 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3982 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003983
Georg Brandl3ee81df2008-05-17 18:14:43 +00003984- Issue #1686386: Tuple's tp_repr did not take into account the
3985 possibility of having a self-referential tuple, which is possible
3986 from C code. Nor did object's tp_str consider that a type's tp_str
3987 could do something that could lead to an inifinite recursion.
3988 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3989 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003991- Issue #1164: It was possible to trigger deadlock when using the
3992 'print' statement to write to a file since the GIL was not released
3993 as needed. Now PyObject_Print() does the right thing along with
3994 various tp_print implementations of the built-in types and those in
3995 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003996
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997- Issue #1147: Exceptions were directly allowing string exceptions in
3998 their throw() method even though string exceptions no longer
3999 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004000
Georg Brandl3ee81df2008-05-17 18:14:43 +00004001- Issue #1096: Prevent a segfault from getting the repr of a very
4002 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004003
Brett Cannon1e534b52007-09-07 04:18:30 +00004004- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005 PyObject_Call() never calling back out to Python code to trigger
4006 recursion depth updates/checks. Required the creation of a static
4007 RuntimeError instance in case normalizing an exception put the
4008 recursion check value past its limit. Fixes crashers
4009 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Patch #1031213: Decode source line in SyntaxErrors back to its

4015 with %G.
4016
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00004024- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004025 __*__ attributes. (Some already existed, e.g., __doc__ and
4026 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004027
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004028- Add -3 option to the interpreter to warn about features that are
4029 deprecated and will be changed/removed in Python 3.0.
4030
Georg Brandl2134e752007-05-21 20:34:16 +00004031- Patch #1686487: you can now pass any mapping after '**' in function
4032 calls.
4033
Collin Winter62903052007-05-18 23:11:24 +00004034- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035 "except E as target:". This is to provide forwards compatibility
4036 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004037
Brett Cannon229cee22007-05-05 01:34:02 +00004038- Deprecate BaseException.message as per PEP 352.
4039
Georg Brandl3ee81df2008-05-17 18:14:43 +00004040- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004041 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004043- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004044 setting a plain string, ie don't expand to single letter identifiers.
4045
Raymond Hettinger13936692007-04-11 18:40:58 +00004046- Request #1191699: Slices can now be pickled.
4047
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004048- Request #1193128: str.translate() now allows a None argument for
4049 translations that only remove characters without re-mapping the
4050 remaining characters.
4051
Georg Brandl5cb76c12007-03-21 09:00:39 +00004052- Patch #1682205: a TypeError while unpacking an iterable is no longer
4053 masked by a generic one with the message "unpack non-sequence".
4054
Neal Norwitzaa754b72007-03-21 06:39:48 +00004055- Remove unused file Python/fmod.c.
4056
Guido van Rossum143b5642007-03-23 04:58:42 +00004057- Bug #1683368: The object.__init__() and object.__new__() methods are
4058 now stricter in rejecting excess arguments. The only time when
4059 either allows excess arguments is when it is not overridden and the
4060 other one is. For backwards compatibility, when both are
4061 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004062 warning later). Also, type.__init__() insists on the same signature
4063 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4066 object to complex using its __complex__() method before falling back
4067 to the __float__() method. Therefore, the functions in the cmath
4068 module now can operate on objects that define a __complex__()
4069 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004070
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071- Patch #1623563: allow __class__ assignment for classes with
4072 __slots__. The old and the new class are still required to have the
4073 same slot names.

4079 ``object.__reduce_ex__()`` is called with an object that is faking
4080 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004081
Georg Brandl3ee81df2008-05-17 18:14:43 +00004082- Patch #1680015: Don't modify __slots__ tuple if it contains an

4086
Georg Brandl7b9c5552007-03-12 14:30:05 +00004087- Bug #1678647: write a newline after printing an exception in any
4088 case, even when converting the value to a string failed.
4089
Georg Brandl871f1bc2007-03-12 13:17:36 +00004090- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091 its argument, if it exists. If not, it will work like before. This
4092 allows customizing the output of dir() in the presence of a
4093 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004094
Collin Winter276887b2007-03-12 16:11:39 +00004095- Patch #922167: Python no longer segfaults when faced with infinitely
4096 self-recursive reload() calls (as reported by bug #742342).

4102 parthensized forms. This means complex(repr(x)) now works instead of
4103 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004104
Georg Brandlaa2321b2007-03-07 00:40:28 +00004105- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106 makes the filenames the warning module prints much more sensible
4107 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004108
Georg Brandl49aafc92007-03-07 00:34:46 +00004109- Variant of patch #697613: don't exit the interpreter on a SystemExit
4110 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111 variable is given, but break into the interactive interpreter just
4112 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00004119
Georg Brandl0fca97a2007-03-05 22:28:08 +00004120- Patch #1674228: when assigning a slice (old-style), check for the
4121 sq_ass_slice instead of the sq_slice slot.
4122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- When printing an unraisable error, don't print exceptions. before
4124 the name. This duplicates the behavior whening normally printing
4125 exceptions.

4134 created a weakref on itself during a __del__ call for new-style
4135 classes (classic classes still have the bug).

4228 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00004229

4734 Python would crash instead of raising an error.

4753 -- the failure just occurred later, with a more cumbersome
4754 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005035- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5036 with RFC 3207 and forgets any knowledge obtained from the server not
5037 obtained from the TLS negotiation itself. Patch contributed by Bill
5038 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005039
Georg Brandl3ee81df2008-05-17 18:14:43 +00005040- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005041 that the SMTP.starttls() caller no longer needs to call ehlo()
5042 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005043 does not claim to support starttls. Adds the
5044 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5125 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5126 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005143 time so that opening a database previously created with the DB_DUP
5144 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5145 opens. Specifically: dictionary assignment to a DB object will
5146 replace all values for a given key when the database allows
5147 duplicate values. DB users should use DB.put(k, v) when they want
5148 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005149

5155 characters with ASCII value less than 32. Also, it correctly quotes
5156 dots only if they occur on a single line, as opposed to the previous
5157 behavior of quoting dots if they are the second character of any
5158 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005159

5481-----
5482
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Unified naming convention for free lists and their limits. All free
5484 lists in Object/ are named ``free_list``, the counter ``numfree``
5485 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5486 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005487
Georg Brandl3ee81df2008-05-17 18:14:43 +00005488- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5489 to ``PyTuple_SetItem``, it can be used to populate a brand new
5490 frozenset; but it does not steal a reference to the added item.

5495 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5496 PyLong_FromSsize_t public functions.

5498- Patch #1720595: add T_BOOL to the range of structmember types.
5499
5500- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5501 ``PyFloat_GetInfo()`` to the float API.
5502
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5504 of w# format code incorrectly truncated the length to an int, even
5505 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5506 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005507
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5509 Py_TYPE and Py_REFCNT.

5526- Fix some leftovers from the conversion from int to Py_ssize_t
5527 (relevant to strings and sequences of more than 2**31 items).
5528
5529- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5530 outside of pystate.c and should not be necessary.
5531
Georg Brandl3ee81df2008-05-17 18:14:43 +00005532- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5533 absolute imports. In earlier versions they might have used relative
5534 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005535
Georg Brandl3ee81df2008-05-17 18:14:43 +00005536- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5537 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005538
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005546- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5547 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5548 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5549 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005550

Georg Brandl3ee81df2008-05-17 18:14:43 +00005564- Removed the macfs module. It had been deprecated since Python 2.5.
5565 This lead to the deprecation of macostools.touched() as it relied
5566 solely on macfs and was a no-op under OS X.
